[Technical Field]

[0003] This invention relates to the field of vehicle engineering technology, and in particular to a multi-functional work vehicle and a multi-functional garden vehicle. [Background Technology]

[0004] Garden vehicles generally refer to vehicles used for outdoor gardening operations, mainly including vehicles used for garden cutting and maintenance.

[0005] Take lawnmowers as an example: Among garden vehicles, lawnmowers are one of the fastest-growing garden operation vehicles in recent years. They are equipped with a cutting platform for cutting and maintaining grass.

[0006] In the current technology, most garden vehicles are equipped with lights only at the front of the vehicle, mainly for illuminating the ground. In actual use, these lights are only turned on at night or when lighting conditions are poor, that is, they are not turned on during the day when lighting conditions are good. When the lights are not turned on, the vehicle is not easy to see, especially by people around who may not be able to see whether the vehicle is in motion, which may pose certain safety hazards.

[0007] All existing garden vehicles suffer from the aforementioned technical problems. Therefore, it is of great importance to propose a multi-functional work vehicle that can solve these problems. [Summary of the Invention]

[0513] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0514] Unless otherwise specified, the terms "set," "connected," and "linked" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. The term "fixed connection" in this invention should also be broadly understood to mean integrally formed, welded, or connected by other fasteners.

[0515] This embodiment discloses a multi-functional work vehicle. Referring to Figure 1, it includes a frame 1 and an outdoor work component. The frame 1 extends along a first direction, which is also the front-rear direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work.

[0516] The multi-functional work vehicle in this embodiment also includes a headlight 3 located at the front of the vehicle and capable of being electrically powered and emitting light.

[0517] In this embodiment, the headlight 3 includes a lighting component that is directly or indirectly disposed on the vehicle frame 1. The lighting component is mainly used to produce a lighting effect on the front of the vehicle.

[0518] Referring to Figures 1 and 2, in some optional embodiments, the multi-functional work vehicle further includes an outer lamp cover 2 fixed to the frame 1, with the lighting assembly disposed on the outer lamp cover 2. Further, the outer lamp cover 2 is fitted to the frame 1 using bolts or other fasteners, thereby achieving the purpose of assembling the lighting assembly to the frame 1.

[0519] Referring again to Figure 1, the figure shows a ride-on lawnmower, which includes a frame 1, a cutter head 4 and other components. The frame 1 is equipped with an outer lamp cover 2, and the outer lamp cover 2 is equipped with a headlight 3.

[0520] Referring to Figure 2, the headlight 3 in this embodiment also includes a daytime running light 318. The daytime running light 318 is disposed on the front center of the frame 1 and faces the front of the vehicle to improve the vehicle's visibility. It is worth noting that the daytime running light 318 being located on the front side of the frame 1 only means that it is located near the front of the frame 1, and does not mean that it is located in front of the frame 1. That is, in the longitudinal direction of the frame 1, a part of the daytime running light 318 may overlap with the frame 1.

[0521] Referring to Figure 2, the lighting assembly in this embodiment includes a left headlight 317 and a right headlight 316. The left headlight 317, daytime running lights 318, and right headlight 316 are arranged sequentially along a second direction, which is the width direction of the vehicle. It is worth noting that although the daytime running lights 318 can emit light and have a certain lighting effect, their main function here is to improve the vehicle's visibility; that is, during the day, the daytime running lights 318 are illuminated and more easily observed. The lighting function is primarily undertaken by the lighting assembly including the left headlight 317 and the right headlight 316. In other embodiments, the daytime running lights 318 participating in and undertaking certain lighting functions should not be construed as exceeding the scope of protection of this embodiment.

[0522] In some optional embodiments, the daytime running light 318 is at least partially located between the left headlight 317 and the right headlight 316; that is, the daytime running light 318 may be partially located between the left headlight 317 and the right headlight 316, or the daytime running light 318 may be completely located between the left headlight 317 and the right headlight 316. It is worth noting that in some embodiments, there is no obvious gap between the left headlight 317 and the right headlight 316. In this embodiment, the daytime running light 318 should be vertically offset from the left headlight 317 and the right headlight 316.

[0523] Furthermore, in some embodiments, the daytime running light 318 is spaced relatively close to the left headlight 317 and the right headlight 316 in the second direction, or there is partial overlap, which makes the light of the daytime running light 318 appear continuous with the light of the left headlight 317 and the right headlight 316, resulting in a better visual effect.

[0524] In some optional embodiments, the daytime running light 318 includes an array of first LED beads 31811, the number of which is 20 to 500. This embodiment uses a relatively large number of LED beads, allowing various lighting effects, such as flowing water effects, to be displayed by controlling the first LED beads 31811 at different positions to flash (light up or turn off) according to a set pattern. In some embodiments, the first LED beads 31811 are LED beads.

[0525] Referring to Figure 3, in some optional embodiments, the daytime running light 318 includes an array of first LED beads 3181, the number of which is 20 to 500. More preferably, the first LED beads 3181 are selected as LED beads, each LED bead arranged in a rectangular array, with 18 to 30 beads per row and 2 to 5 rows. Further, to simplify the configuration of the first LED beads 31811, the daytime running light 318 also includes a central light plate 3181, in which the first LED beads 31811 are integrated. Referring to Figure 3, in one specific embodiment, the daytime running light 318 includes two rows of first LED beads 31811 integrated into the central light plate 3181.

[0526] In some optional embodiments, the luminous power of the first LED 31811 is 0.01W to 0.5W. In one embodiment, the luminous power of the first LED 31811 is 0.01W, and the number of first LEDs 31811 should be 200 to 500. When operating, it can produce relatively conspicuous brightness, thereby improving vehicle visibility. In another embodiment, the luminous power of the first LED 31811 is 0.2W, and the number of first LEDs 31811 should be 20 to 50. This also produces relatively conspicuous brightness when operating, thereby improving vehicle visibility. In yet another embodiment, the luminous power of the first LED 31811 is 0.5W, and the number of first LEDs 31811 should be 10 to 30. This also produces relatively conspicuous brightness when operating, thereby improving vehicle visibility.

[0527] In some optional embodiments, in order to enable the daytime running light 318 to have relatively high brightness and effectively improve the vehicle's visibility, its rated luminous power should be in the range of 5W to 15W.

[0528] Furthermore, the aforementioned power is the rated power of the first lamp bead 31811. If the total rated power of the daytime running light 318 is relatively high and the headlights are on, the vehicle can reduce the power of the first lamp bead 31811 of the daytime running light 318 to avoid excessive brightness and unnecessary energy waste.

[0529] Furthermore, the main function of the daytime running lights 318 is to improve the visibility of the vehicle, especially during the day when ambient light is good. When the vehicle is operating at night, the left and right headlights are turned on to produce a better lighting effect. Since the left and right headlights will inevitably increase the visibility of the vehicle, the power of the daytime running lights 318 is generally reduced when the left and right headlights are on, that is, the brightness of the daytime running lights 318 is reduced, thereby reducing the heat generated by the daytime running lights 318.

[0530] Furthermore, in some optional embodiments, the daytime running lights 318 remain off when the vehicle's left and right headlights are on, because there is no need for the daytime running lights 318 to be illuminated to improve the vehicle's visibility at this time.

[0531] As described above, when the left and right daylight lamps are lit, the daytime running light 318 does not need to operate at its rated power. That is, the actual luminous power of the left and right daylight lamps 317, 318, and 316 when lit simultaneously is not equal to the sum of their rated power. In some optional embodiments, when the left and right daylight lamps 317, 318, and 316 are lit simultaneously, the left and right daylight lamps operate at their rated power, while the daytime running light 318 operates at reduced power. The actual luminous power is 14W to 30W.

[0532] In some optional embodiments, the headlight unit 3 further includes a headlight controller for controlling at least the operation of the first lamp bead 31811, and a vehicle controller coupled to the headlight controller is disposed on the frame 1. The vehicle controller controls the operating state of each lamp bead in the headlight assembly through the headlight controller. It should be noted that the vehicle controller being disposed on the frame 1 as described in this specification does not limit the direct or indirect cooperation between the vehicle controller and the frame, nor does it limit the specific location of the vehicle controller. In some more specific embodiments, the vehicle controller is disposed in the middle of the vehicle, in which case the distance between the vehicle controller and the front and rear of the vehicle is approximately equal. In another optional embodiment, the vehicle controller is disposed approximately in the front part of the vehicle, in which case the vehicle controller is closer to the headlight unit, i.e., signal transmission with the headlight is more convenient. In another optional embodiment, the vehicle controller is disposed approximately in the rear part of the vehicle, and the power system (battery pack, BMS, etc.) of the gardening vehicle or outdoor work vehicle is located in the rear position of the vehicle, in which case signal transmission between the vehicle controller and the power system is more convenient.

[0533] Referring to Figure 3, in one of the optional embodiments, the daytime running light 318 includes a center lamp plate 3181, with the first LED beads 31811 arranged in an array on the center lamp plate 3181. The center lamp plate 3181 is placed vertically so that the first LED beads 31811 face the front of the vehicle. The headlight controller is disposed on the rear wall of the center lamp plate 3181. Because the power of the daytime running light 318 is less than that of the headlights, when all the LED beads of the headlight section 3 are working, the temperature of the center lamp plate 3181 will be lower than that of the light-emitting panels of the left and right headlights 316. Especially when the left and right headlights and the daytime running light 318 are all on, the reduced brightness of the daytime running light 318 can reduce its heat generation. The headlight controller includes a temperature-sensitive MCU (microcontroller), and its placement on the center lamp plate 3181 can reduce the probability of failure caused by the high temperature of the headlight panels.

[0534] It is worth noting that, due to the physical structure of the LED beads, the minimum number of first LED beads 31811 that can be lit at one time is one. Therefore, the more first LED beads 31811 there are, the higher the control precision of the lighting effect when they flash.

[0535] In some embodiments, the number of first LED beads 31811 is approximately 20. To achieve relatively high brightness during operation, LED beads with a luminous power of 0.4W to 0.5W are generally selected. In this embodiment, a relatively preferred arrangement is a single-row linear distribution of the first LED beads 31811, which facilitates a better lighting effect.

[0536] In some embodiments, referring to Figure 3, the number of first LED beads 31811 is approximately 40. In order to make it have relatively high brightness when working, but not so high brightness that it will generate too much heat, LED beads with a luminous power of approximately 0.2W are generally selected. In this embodiment, the first LED beads 31811 are relatively preferably arranged in a double row linear distribution in order to show a better lighting effect.

[0537] In some embodiments, the number of first LED beads 31811 is significantly greater than 40 and less than or equal to 500. In this case, the relatively large number of first LED beads 31811 necessitates a lower luminous power to avoid excessive heat generation. Generally, LED beads with a luminous power of 0.01W to 0.2W are selected. In this embodiment, it is relatively preferred that the first LED beads 31811 are configured in multiple rows, with a sufficiently small spacing between each pair of adjacent LED beads to achieve a better lighting effect. Because the change observed by the naked eye is smaller when two closely spaced LED beads alternately light up, it is easier to display a smoother flowing light effect.

[0538] In summary: for different numbers of the first LED 31811, LEDs with different luminous power should be selected, with the luminous power ranging from 0.01W to 0.5W.

[0539] In some optional embodiments, the daytime running light 318 further includes a second LED (not shown) located within the left headlight 317 and / or the right headlight 316. This second LED works in conjunction with the first LED 31811 to display various lighting effects. Specific displayable lighting effects include the first LED 31811 and the second LED flashing alternately at a defined power and / or frequency. It is worth noting that the LEDs configured for illumination within the left and right headlights are distinct from the first LED 31811 and the second LED. While the second LED is physically located within the left headlight 317 and the right headlight 316, it participates in the lighting effects of the daytime running light 318, such as alternately illuminating to create a flowing light effect under the control of the user or vehicle control system. Because the second LED is located within the left headlight 317 and the right headlight 316, the coverage area of ​​the flowing light effect is increased, resulting in a better visual effect.

[0540] Referring to Figure 3, in one of the optional embodiments, the daytime running light 318 further includes a central light plate 3181, on which the first LED beads 31811 are arranged in an array. Since the first LED beads 31811 are integrated into the central light plate 3181, the assembly of the first LED beads 31811 can be simplified. Correspondingly, the lighting beads in this embodiment are also LED beads. To further simplify the assembly of the lighting beads, the left lighting lamp 317 and the right lighting lamp 316 also include lighting plates, on which the lighting beads are disposed.

[0541] In some optional embodiments, a headlight controller (not shown) for controlling the daytime running lights 318 and the lighting components is disposed on the center lamp panel 3181, and a vehicle controller (not shown) coupled to the headlight controller is disposed on the frame 1. In this application, the left headlight 317 and right headlight 316 are responsible for illumination, while the daytime running lights 318 are responsible for improving vehicle visibility. Therefore, the luminous power of the left headlight 317 and right headlight 316 should be greater than that of the daytime running lights 318. When the headlights and daytime running lights 318 are working normally, the heat generated by the headlights will also be greater than that of the daytime running lights 318, resulting in the temperature of the headlight panel being higher than that of the center lamp panel 3181. As the headlight controller is a relatively temperature-sensitive device, placing it on the center lamp panel 3181 can reduce the probability of failure caused by the high temperature of the headlight panel.

[0542] Furthermore, as mentioned above, the daytime running light 318 is positioned between the left headlight 317 and the right headlight 316, and the headlight controller is also necessarily located between the left and right headlights. The headlight controller is connected to the left headlight 317 and the right headlight 316 via wires, so that the distance between the headlight controller and the left headlight 317 and the right headlight 316 is approximately equal, and the signal transmission delay is also almost the same, reducing the impact of signal delay on the synchronization of the left headlight 317 and the right headlight 316.

[0543] As mentioned earlier, the first LED 31811 and the second LED of the daytime running light 318 can be lit and extinguished in a specific sequence to produce various lighting effects such as flowing light effects. In reality, the realization of these lighting effects relies on the controller sending control signals to the LEDs in real time. In the embodiments of this specification, the control information for various lighting effects is stored in the headlight controller. When various lighting effects need to be displayed, the vehicle controller only needs to send a simple lighting effect command to the headlight controller, which can then retrieve the corresponding control signal and send it to the LED of the daytime running light 318. During this process, the control signals with larger data volumes are sent only from the headlight controller to the LEDs, rather than directly from the vehicle controller, avoiding signal congestion due to excessive data volume. Especially when the number of LEDs in the daytime running light 318 is large or when complex lighting effects are achieved, the physical spacing between these data sent from the headlight controller to the LEDs of the daytime running light 318 is significantly smaller, resulting in higher overall communication efficiency.

[0544] In some optional embodiments, the first LED 31811 of the daytime running light 318 and the headlight controller are located on two surfaces of the center light board 3181, respectively. That is, the communication between the headlight controller and the first LED 31811 is intra-board communication, which not only has the technical effect of high communication efficiency mentioned above, but also has the advantages of high speed, low latency and low power consumption. Especially when the number of first LEDs 31811 is significantly large, the technical feature of this intra-board communication can effectively ensure that the first LEDs 31811 can display more complex lighting effects.

[0545] Correspondingly, since the vehicle controller does not need to send specific lighting effect control signals to the LEDs, the computing power burden on the vehicle controller is reduced, and the burden on the communication lines connected to the vehicle controller is reduced. Thus, the cost of the vehicle controller and communication lines can be appropriately reduced while ensuring normal functionality.

[0546] In some optional embodiments, the vehicle controller connects to the headlight controller via a control protocol to send control signals to the headlight controller.

[0547] Specifically, in some optional embodiments, the control protocol includes one or more of the following: TCP / IP, RS-232, RS-422, RS-485, MOD BUS, and CAN. Free control of the vehicle lights can be achieved based on any one or more of these protocols.

[0548] Furthermore, the main function of the daytime running lights 318 is to improve the vehicle's visibility, especially during the day when ambient light is good. When the vehicle is operating at night, the left headlights 317 and right headlights 316 are turned on to produce a better lighting effect. Since the illumination of the left headlights 317 and right headlights 316 will inevitably increase the vehicle's visibility, the power of the daytime running lights 318 is generally reduced when the left headlights 317 and right headlights 316 are on, that is, the brightness of the daytime running lights 318 is reduced, thereby reducing the heat generated by the daytime running lights 318. Therefore, when the headlight controller controls the left headlights 317, right headlights 316, and daytime running lights 318 to work simultaneously, the heat generated by the daytime running lights 318 will be significantly lower and will not affect the headlight controller.

[0549] In some optional embodiments, the headlight controller is disposed on one surface of the center lamp panel 3181, and the daytime running light 318 LEDs are disposed on the other surface of the center lamp panel 3181. That is, the center lamp panel 3181 serves as a control board to support the controller, while the LED units of the daytime running light 318 are disposed on the other surface of the control board, thereby maximizing the utilization of the internal space of the headlight section.

[0550] Referring to Figure 3, in one of the optional embodiments, the daytime running light 318 includes a center lamp plate 3181 and an array of first LED beads 31811 disposed on the center lamp plate 3181. The headlight controller is disposed on the center lamp plate 3181, and the headlight controller and the first LED beads 31811 are disposed on different surfaces of the center lamp plate 3181. Specifically, in one optional embodiment, the first LED beads 31811 are located on the front surface of the center lamp plate 3181, and the headlight controller is located on the rear surface of the center lamp plate 3181. The first LED beads 31811 of the daytime running light 318 are coupled to the headlight controller, that is, the on / off state and brightness of the daytime running light 318 are controlled by the headlight controller.

[0551] In one optional embodiment, the center lamp board 3181 is a single, complete board. In another optional embodiment, the center lamp board 3181 includes at least two spaced-apart sub-boards; that is, the center lamp board 3181 is not a single, complete board. The sub-boards are connected by wires. At least one of the sub-boards is equipped with a matrix arrangement of first LED beads 31811, and at least one of the sub-boards is equipped with a headlight controller. The split-type center lamp sub-boards facilitate space configuration: because the headlight controller needs to control the lighting, extinguishing, and flashing frequency of each first LED bead 31811 and the illumination LED beads, it not only has an MCU (microcontroller) but also includes various electrical components such as MOSFETs, resistors, and capacitors. When the space on one sub-board is insufficient to fully accommodate these components, they can be placed on the other sub-board. The other sub-board can then be configured in other locations around it, or even the two sub-boards can be arranged in layers, significantly reducing the overall space occupied by the center lamp board 3181, hence the aforementioned space-efficient configuration.

[0552] In embodiments where the central lamp board 3181 is not a complete board, communication between the various central lamp sub-boards is inter-board communication. Its communication efficiency is slightly lower than that of intra-board communication, but for the needs of achieving lighting control, which does not involve a large amount of data, its communication efficiency is sufficient to achieve various lighting effects.

[0553] In another optional embodiment, at least two center lamp dividers are provided with first lamp beads 31811, but the spacing between adjacent center lamp dividers is small and does not affect the spacing between the first lamp beads 31811 on the two center lamp dividers. From the perspective of external visual effect, the two center lamp dividers in this embodiment are no different from a whole center lamp plate 3181.

[0554] In one of the optional embodiments, as mentioned above, the first lamp bead 31811 at the center lamp plate 3181 is an LED lamp bead. The center lamp plate 3181 is connected to a center lamp cover 3182 with a light transmittance greater than 60%. Referring to Figures 4 and 5, the inner wall and / or outer wall of the center lamp cover 3182 are arranged with concave and convex structures. The concave and convex structures refract and reflect the light emitted by the first lamp bead 31811, thereby causing the light emitted by the first lamp bead 31811 to be scattered due to reflection or refraction. This allows the light of the daytime running light 318 to be emitted in all directions under the above-mentioned scattering effect, increasing the observable area of ​​the daytime running light 318. That is, the daytime running light 318 can be observed from various places in front of the vehicle, effectively improving the vehicle's visibility.

[0555] Furthermore, in one of the optional embodiments, referring to Figure 6, which is a partial enlarged view of Figure 4, the outer wall of the central lampshade 3182 is configured as an array of curved surfaces 31821, with each curved surface 31821 adjacent to each other so that the outer wall of the central lampshade 3182 does not have a completely flat surface, thus preventing the light at the corresponding position from shining outward directly and reducing its light diffusion range.

[0556] Furthermore, in one of the optional embodiments, referring to Figure 7, which is a partial enlarged view of Figure 5, the inner wall of the lampshade 3182 is configured as an array of distributed ring structures 31822. Each ring structure 31822 is composed of multiple concentric rings. Correspondingly, the position of each ring is also curved to produce a more obvious refraction effect and prevent the light at the corresponding position from shining outward directly, thereby reducing its light diffusion range.

[0557] In some optional embodiments, the shortest distances of the daytime running light 318 from the left headlight 317 and the right headlight 316 are equal, meaning the daytime running light 318 is centered in the left-right direction relative to the left and right headlights 317 and 316. Furthermore, this left-right centering serves to make the daytime running light 318 appear symmetrical. In this embodiment, the components affecting its apparent symmetry are the first LED 31811 and the central lampshade 3182, especially the portion of the central lampshade 3182 that is observable from the outside; it should maintain a symmetrical appearance. An asymmetrical portion of the central lampshade 3182 that is not directly observable from the outside should not be considered a breach of the protection scope of this embodiment.

[0558] In some optional embodiments, the ratio of the daytime running light 318 to the frame 1 in the second direction is 0.2 to 1. In this embodiment, the daytime running light 318 serves to improve vehicle visibility; its relatively large size does not negatively impact illumination or other effects. When the daytime running light 318 is equal to or approximately equal to the frame 1 in the second direction, the left headlight 317 and right headlight 316 should at least partially overlap with the daytime running light 318 in the left-right direction (vehicle width direction).

[0559] In some optional embodiments, referring to Figure 3, the left headlight 317 and right headlight 316 are equipped with a focusing section and lighting bulbs. That is, the left headlight 317 and right headlight 316 are configured as focusing lamps capable of reflecting LED light into parallel (or nearly parallel) light. The light from the lighting bulbs, after being focused by the focusing section, illuminates the front of the vehicle. In a more specific embodiment, the light emitted by the lighting bulbs, due to the focusing effect of the focusing section, results in an illuminance of 10 lux to 60 lux at a distance of 10 meters in front of the vehicle. This illuminance range meets basic lighting needs. In another optional embodiment, the lighting assembly produces a light intensity of 20 lux to 40 lux at a distance of 10 meters in front of the multi-functional work vehicle. In yet another optional embodiment, the lighting assembly produces a light intensity of 25 lux to 35 lux at a distance of 10 meters in front of the multi-functional work vehicle. This is used to provide illumination within 10 meters in front, allowing the user to promptly obtain information about the ground conditions within 10 meters in front of the vehicle.

[0560] In some optional embodiments, referring to Figure 8, which shows a schematic diagram of the headlight 3 emitting light in the direction of the vehicle's front, the light from the left headlight 317 and the right headlight 316 overlaps at a distance X in front, so that the left headlight 317 and the right headlight 316 together achieve sufficient illumination of the overlapping position. In some specific embodiments, X is 10 meters, and the headlight produces a light intensity of at least 30 lux at the overlapping position of the lights at this 10-meter distance.

[0561] In some optional embodiments, at least one of the LED lamp units has a power efficiency of 50 lm / W to 150 lm / W. In some more specific embodiments, at least one of the LED lamp units has a power efficiency of 75 lm / W to 125 lm / W. More specifically, in one embodiment, the LED lamp unit has a power efficiency of 100 lm / W. This relatively high power efficiency results in high energy utilization and relatively low power consumption for the integrated headlight unit 3.

[0562] In some optional embodiments, to achieve a high illumination effect 10 meters in front of the vehicle, the sum of the rated luminous power of each of the lighting beads is 12W to 20W. More specifically, in some optional embodiments, the rated luminous power of a single lighting bead is 0.5W to 5W. To meet the above illuminance requirements, an appropriate number of lighting beads can be selected. In some optional embodiments, the rated luminous power of a single lighting bead is 1W to 3W; more specifically, in some embodiments, the rated luminous power of a single lighting bead is 2W. It should be further noted that the above description of power does not mean that the rated power of each lighting bead must be the same. That is, as long as the range of the sum of the above rated luminous power is met, the combination of lighting beads with different power should also be included in the protection scope of the above embodiments.

[0563] In some optional embodiments, the LED light unit has a color rendering index (CRI) of 50%–98% and a color temperature of 5000K–6500K. In some specific embodiments, the LED light unit has a CRI of 50%–80%, which meets the lighting needs of most tasks such as lawn mowing. In another optional embodiment, LEDs with a higher CRI are selected to better reproduce the colors of objects. This is especially beneficial when users need illumination to observe certain details, allowing them to quickly and effectively distinguish details. For example, the light from the illumination unit can be used for nighttime maintenance of lawnmowers or other equipment. The 5000K–6500K color temperature also helps to better reproduce the original colors of objects.

[0564] In some optional embodiments, the multi-functional work vehicle includes a headlight base 31 and a headlight cover 32 connected to the frame 1 and cooperating with each other to form a closed space. The lighting components and daytime running lights 318 are disposed in the closed space. The headlight cover 32 is at least partially configured as a transparent part, and light in the closed space can be irradiated to the outside through the transparent part.

[0565] In some optional embodiments, referring to Figure 1, a ride-on lawnmower is disclosed, which is equipped with an integrated headlight assembly. The ride-on lawnmower in the figure includes multiple components such as a frame 1 and a cutter head 4, wherein an outer lamp cover 2 is disposed on the frame 1, and the headlight assembly is disposed inside the outer lamp cover 2. In some more specific embodiments, the headlight assembly is also the aforementioned headlight section 3.

[0566] In some optional embodiments, the headlight unit 3 of the multi-functional work vehicle includes a cover and a lamp body connector 33, that is, the headlight assembly includes a cover and a lamp body connector 33, wherein the cover includes a front cover and a rear cover distributed in the front-rear direction. In this embodiment, the front cover and the rear cover together form the aforementioned enclosed space, and the front cover and the rear cover in this embodiment correspond to the aforementioned headlight cover 31 and headlight socket 32, respectively.

[0567] Referring to Figure 11, in one of the optional embodiments, the lighting body connector 33 is connected to a first lighting assembly, a second lighting assembly, and a third lighting assembly located between the first lighting assembly and the second lighting assembly; wherein the first lighting assembly and the second lighting assembly are located on the left and right sides of the ride-on lawnmower, respectively, to illuminate the general front area of ​​the ride-on lawnmower.

[0568] The third lighting assembly is disposed between the first lighting assembly and the second lighting assembly to increase the function of the headlight unit 3. For example, the third lighting assembly may be configured as an enhanced lighting assembly to increase the maximum illumination brightness of the headlights, or as a lighting assembly with product identification, or other lighting assembly that enhances the personalization of the product.

[0569] In some optional embodiments, the first lighting assembly, the second lighting assembly, and the third lighting assembly correspond to the aforementioned right lighting 316, left lighting 317, and daytime running light 318, respectively.

[0570] Referring to Figure 11, the headlight body connector 33 is a component distinct from the headlight socket 32 ​​and the headlight cover 31. Since the headlight portion 3 in this embodiment is relatively large, the headlight body connector 33, as a component located within a confined space and connecting the left headlight 317, right headlight 316, and daytime running light 318, effectively assists in the positioning of these components. Especially during assembly, where the left headlight 317, daytime running light 318, and right headlight 316 are arranged sequentially along the vehicle's width, the presence of the headlight body connector 33 simplifies the assembly and positioning of these components.

[0571] In an embodiment described in part of this specification, the above-mentioned lamp body connector is configured, and the first lamp assembly, the second lamp assembly, and the third lamp assembly are all disposed on the lamp body connector. This integrates the three originally independent lamp assemblies into a single headlight assembly. This assembly should be manufactured before vehicle assembly. During vehicle assembly, the headlight assembly is assembled as a whole into the vehicle. Compared with the prior art where two or more lamps are assembled separately into the vehicle, this significantly improves vehicle assembly efficiency and reduces production costs.

[0572] For example, in some optional embodiments, the left headlight 317 and right headlight 316 are directly connected to the front lamp holder 32 via bolts or other fasteners, and the daytime running light 318 is connected to the headlight body connector 33 via bolts or other fasteners. The headlight body connector 33 is then connected to the front lamp holder 32 via fasteners. The headlight body connector 33 is not directly connected to the left headlight 317 and right headlight 316 via fasteners, but it is indirectly connected to the left headlight 317 and right headlight 316 via the front lamp holder 32. It should be noted that the connection of the daytime running light 318 to the headlight socket 32 ​​via the headlight body connector 33 is not merely for assembly purposes. Because the left headlight 317 and right headlight 316 require reflectors or lenses to create a focused light effect, along with other auxiliary structures for their installation, the actual space occupied by the left and right headlights is inevitably larger than the visually illuminated portion. This encroaches on the left-right space of the headlight socket 32's enclosed area, making it difficult to directly assemble the daytime running light 318 to the headlight socket 32, especially when the headlight assembly is in operation and there is no significant left-right separation between the daytime running light 318 and the left and right headlights 317 and 316. The main body connector 33 of the lighting fixture is significantly larger and extends to the edges of the left lighting fixture 317 and the right lighting fixture 316. This means that the presence of the main body connector 33 makes the visual effect of the left lighting fixture 317, the right lighting fixture 316, and the daytime running lights 318 more coherent in the left-right direction. As an intermediate structural component for assembling the daytime running lights 318 to the headlight housing 32 and / or the headlight cover 31, the main body connector 33 assists in the assembly of the daytime running lights 318, thus simplifying the assembly process.

[0573] In another optional embodiment, the left headlight 317 and right headlight 316 are connected to the headlight body connector 33 by bolts or other fasteners, and the daytime running light 318 is connected to the headlight socket 32 ​​by bolts or other fasteners. The left headlight 317, right headlight 316, and daytime running light 318 are then assembled into the headlight unit 3 by fitting the headlight body connector 33 into the headlight socket 32. Similarly, in this embodiment, the headlight body connector 33 directly connects to the left headlight 317 and right headlight 316, and indirectly connects to the daytime running light 318.

[0574] In some optional embodiments, the left headlight 317 and the right headlight 316 are directly mounted to the front lamp holder 32, and the daytime running light 318 is directly mounted to the headlight body connector 33. The headlight body connector 33 is mounted to the front lamp holder 32 and then connected to the left headlight 317 and the right headlight 316. In this embodiment, the left headlight 317 and the right headlight 316 are not only directly connected to the front lamp holder 32, but also directly connected to the headlight body connector 33, making the connection between the left headlight 317 and the right headlight 316 more stable. Especially under conditions such as severe vehicle vibration, its more stable structure makes its position and orientation more stable, and there will be no situation such as the lighting direction being deviated.

[0575] The first lighting assembly (i.e., the right lighting lamp 316) includes multiple LED lamp units and reflector units; the second lighting assembly (i.e., the left lighting lamp 317) also includes multiple LED lamp units and reflector units. The LED lamp units serve as light sources, and the reflector units reflect the light from the LED lamp units, thus changing the direction of the light path. This means that the LED lamp units do not need to directly face the front of the vehicle; the reflector units effectively direct the light towards the front of the vehicle. This also facilitates the planning of the lighting assembly's position and allows for more personalized lighting shapes by adjusting the position and shape of the reflectors.

[0576] In some optional embodiments, a plurality of LED units of the first lighting assembly and / or the second lighting assembly are disposed in the upper region of the lighting body support 33, that is, at least one of the LED units of the first lighting assembly and the second lighting assembly is disposed in the upper region of the lighting body support 33 and the support faces downward to emit light; the emitted light is reflected forward by the reflector unit to produce an illumination effect.

[0577] For multi-functional work vehicles used for gardening operations, such as ride-on lawnmowers, the integrated headlights (front light units) are often positioned relatively low off the ground, meaning they are generally significantly lower than the user's height. The downward-facing LED light units cannot emit light directly into the user's eyes; therefore, the user cannot directly see the LED light units, and what the user sees is only the light reflected by the reflector units.

[0578] Specifically, in one particular embodiment, referring to Figure 9, which is a structural schematic diagram of the left light lamp 317 and the right light lamp 316. As shown in the figure, the left light lamp 317 includes a left light-emitting plate 3171 and a left reflector unit, and the right light lamp 316 includes a right light-emitting plate 3161 and a right reflector unit. Multiple LED light units of the left light lamp 317 are disposed on the lower wall of the left light-emitting plate 3171, and multiple LED light units of the right light lamp 316 are disposed on the lower wall of the right light-emitting plate 3161. That is, the LED light units emit light towards the reflector units at corresponding positions, and the reflector units reflect the light and illuminate the front of the vehicle to achieve the lighting effect.

[0579] In some optional embodiments, the left headlight 317 and / or the right headlight 316 are implemented as spotlights, daytime running lights, or turn signals. Further, in some specific optional embodiments, the left headlight 317 and / or the right headlight 316 are implemented as spotlights, meaning they are capable of focusing light into nearly parallel beams and emitting them outwards to increase the illumination brightness of the illuminated area. Referring to Figures 3 and 9, the left reflector unit and the right reflector unit are configured as reflective tiles, specifically, the left reflector unit is configured as a left reflective tile 3172, and the right reflector unit is configured as a right reflective tile 3162. The reflective tiles reflect light and create a focusing effect, thus achieving a focusing effect and increasing the illumination brightness in front of the vehicle.

[0580] In some specific alternative embodiments, the left headlight 317 and / or the right headlight 316 are implemented as daytime running lights, i.e., they emit light to the outside world to improve the vehicle's visibility in well-lit environments. In some specific alternative embodiments, the left headlight 317 and / or the right headlight 316 are implemented as turn signals, with the corresponding headlight assembly activating when the vehicle is turning to inform surrounding road users that it is currently turning, thereby improving safety.

[0581] In some optional embodiments, the third lighting assembly includes a plurality of LED light units disposed at the center of the lighting body connector 33 along the second direction. This central position makes the headlights symmetrical in the left-right direction, providing a stronger visual experience. Choosing LEDs as its light source allows the third lighting assembly to possess the advantages of LEDs, such as energy saving and long lifespan.

[0582] Referring to Figure 10, which is a front view of the first, second, and third lighting assemblies, in some optional embodiments, the third lighting assembly is implemented as a daytime running light (daytime running light 318), meaning it emits light to improve vehicle visibility in well-lit environments. This allows personnel around the lawnmower to more quickly identify this potentially dangerous machine, thereby improving safety during operation.

[0583] Referring to Figures 2, 3, and 4, in some optional embodiments, the third lighting assembly further includes a light-diffusing element fixedly disposed on the lighting body connector 33. The light-diffusing element is used to diffuse the light from the third lighting assembly outwards. As mentioned above, the function of the third lighting assembly is to improve the visibility of the vehicle. Its diffused light emission effect allows for a larger illumination area, meaning that a wider range of personnel can spot the working vehicle through the light emitted by the third lighting assembly.

[0584] In one of the specific optional embodiments, the third lighting assembly is configured as a daytime running light 318, and the daytime running light 318 is configured with a first LED bead 31811, and the first LED bead 31811 is an LED lamp unit. The diffuser is configured as a central lamp cover 3182 covering the LED lamp unit of the third lighting assembly. Referring to Figures 4, 5, 6, and 7, the inner wall and / or outer wall of the central lamp cover are arranged with an array of concave and convex structures. The concave and convex structures refract and reflect the light emitted by the first LED bead 31811, thereby causing the light emitted by the first LED bead 31811 to be scattered due to reflection or refraction. This allows the light of the daytime running light 318 to be emitted in all directions under the above-mentioned scattering effect, increasing the observable area of ​​the daytime running light 318, that is, the daytime running light 318 can be observed from various places in front of the vehicle, effectively improving the vehicle's visibility.

[0585] In some optional embodiments, the transmittance represents the ability of light from the first LED 31811 in the daytime running light 318 to pass through the central lampshade 3182. In order to maintain the daytime running light 318 to produce relatively suitable brightness and power, in some optional embodiments, the transmittance of the central lampshade 3182 should not be less than 60%, but due to cost and material performance limitations, the transmittance is generally not higher than 95%.

[0586] In some optional embodiments, both the first lighting assembly and the second lighting assembly reflect light from the LED unit via a reflector unit. Further, the reflector unit includes a one-piece injection-molded reflector body and a coating formed on the surface of the reflector body. The one-piece injection-molded reflector body surface is configured to be relatively smooth, without seams that would occur when two or more separate parts are joined, thus preventing light from being reflected in an undesirable direction due to surface roughness such as seams. The purpose of the coating is to increase its reflectivity and improve light utilization.

[0587] In some optional embodiments, the visible light reflectance of the coating is greater than 75%. In some specific embodiments, the coating is selected as aluminum plating, processed using a vapor aluminum process, which generally achieves a reflectance of 90% to 95%. In particular, the reflectance of the coating can be increased to 98% by changing other processes; the specific processes are existing technologies and will not be described in detail here.

[0588] In some optional embodiments, the reflector unit is configured as a component with a light-focusing effect, that is, the reflector unit is implemented as the aforementioned light-focusing part, and the light emitted by the lighting lamp beads is focused by the light-focusing part to produce a stronger lighting effect.

[0589] In some optional embodiments, the focusing element is configured as a lens and / or a reflector, and the illumination bulbs emit light toward the focusing element. In another optional embodiment, the focusing element is a convex lens facing forward of the vehicle, which has the effect of focusing the diffused light into a beam that illuminates only forward.

[0590] Referring to Figures 2, 3, and 9, in another optional embodiment, the focusing part is a reflective tile. In the figures, the left lamp 317 is equipped with a left reflective tile 3172, and the right lamp 316 is equipped with a right reflective tile 3162. The reflective tile has a coating on the side near the lamp bead, which has a strong reflective effect. At the same time, the reflective tile has a bowl-shaped concave surface. The light emitted by the lamp bead is reflected by the concave surface to form a nearly parallel light beam that shines forward, thereby producing a stronger lighting effect for a longer distance in front of the vehicle.

[0591] In some optional embodiments, by configuring a focusing part in the headlight assembly to focus the light emitted by the lighting bulb, the light from the lighting bulb shines forward as parallel or nearly parallel light, thereby providing sufficient illumination for operation up to 10 meters in front of the vehicle.

[0592] In some optional embodiments, the outer contour of the reflector unit of the first and / or second lighting assembly is approximately polygonal, and further, the polygonal number of sides of the outer contour of the reflector is 4 to 11. Referring to Figures 9 and 10, in this embodiment, the outer contour of the reflector (left reflector 3172, right reflector 3162) is approximately hexagonal. As described above, the embodiments of this application include a first lighting assembly and a second lighting assembly, which are located on both sides of the front of the vehicle, resembling human eyes when viewed from the front. The reflector in the lighting assembly is used to reflect light outward, that is, when looking at the vehicle from the front, the light is emitted outward from the reflector. In this application, the reflector is configured as a polygon, which makes the lighting assembly look like sharper eyes, resulting in a stronger visual effect.

[0593] In one more specific embodiment, the polygon of the reflector unit has exactly two vertices located at the leftmost and rightmost edges, respectively. That is, one vertex is located at the leftmost edge and the other vertex is located at the rightmost edge, with the vertex being the intersection of the two edges. This makes the reflector look more like a relatively sharp human eye.

[0594] In some optional embodiments, the outer contour of the diffuser is generally a long, narrow polygonal structure. Further, the polygonal shape of the diffuser's outer contour has 4 to 11 sides; referring to Figures 4 and 10, in this embodiment, the outer contour of the diffuser is generally a long, narrow isosceles trapezoid.

[0595] To further clarify: the outer contour of the aforementioned reflector and diffuser specifically refers to the contour that faces the front of the vehicle and is seen by the user; in some embodiments, the reflector and diffuser are set to other shapes, but if the aforementioned contour is displayed in front of the vehicle but is blocked by other obstructions, it should also be included in the protection scope of the above embodiments.

[0596] As described above, the third lighting assembly of this application is located between the first lighting assembly and the second lighting assembly. The LED light assembly in the third lighting assembly emits light towards the diffuser, which refracts the light and directs it toward the front of the vehicle. That is, when viewed from the front, the light from the third lighting assembly is emitted outward through the diffuser, and its polygonal shape also makes it more angular and improves the visual effect.

[0597] In some optional embodiments, the first and second lighting assemblies are mirror-symmetrical with respect to a plane of symmetry that is perpendicular to the ground and extends forward of the lawnmower, with a first direction parallel to the plane of symmetry, which is perpendicular to both the left-right and vertical directions of the vehicle. This mirror-symmetry characteristic enhances their aesthetic appeal.

[0598] In some optional embodiments, the third lighting assembly is located in front of the first lighting assembly and the second lighting assembly. In particular, the first lighting assembly and the second lighting assembly have reflectors with recessed portions that make them look more like deep human eyes. Especially when only the third lighting assembly is lit, while the first lighting assembly and the second lighting assembly are not lit, its deep visual effect makes it more aesthetically pleasing, thus providing a lamp body structure that makes the light more profound.

[0599] In one of the optional embodiments, referring to Figures 11 and 12, the front cover and rear cover form a first region 34, a second region 35, and a third region 36 that are interconnected. The first lighting assembly (right lighting 316), the second lighting assembly (left lighting 317), and the third lighting assembly (daytime running light 318) are respectively arranged sequentially in the first region 34, the second region 35, and the third region 36. The maximum depth of the third region 36 along the front-to-back direction of the lawnmower is less than the maximum depth of the first region 34 and the second region 35. Further, the first region 34 and the second region 35 are located on both sides of the third region 36. The greater depth of the first region 34 and the second region 35 is used to configure reflectors with recesses, and the greater depth allows them to be configured as reflectors with stronger light-gathering effects; conversely, the third region 36 does not need to be configured with reflectors for light gathering, so its depth is smaller.

[0600] In some optional embodiments, as previously mentioned, referring to Figure 12, which is a structural schematic diagram of the headlight housing 31, the maximum depth of the third region 36 along the front-rear direction of the lawnmower is 30mm to 90mm. The maximum depth of the first and / or second lighting assemblies along the front-rear direction of the lawnmower is 70mm to 150mm. Especially when the depth of the first and second regions 34 and 35 is large, resulting in a large external profile at the corresponding positions that is difficult to grip, the relatively small depth of the third region 36 directly results in a smaller external dimension of the integrated headlight assembly at the third region 36, thus facilitating grip. That is, during assembly and maintenance, the user can easily pick up the integrated headlight assembly with one hand.

[0601] In some optional embodiments, at least a portion of the front cover (front lamp cover 32) is configured as a transparent portion, through which light emitted by the first, second, and third lighting assemblies can be transmitted to the outside to produce an illumination effect. It should be noted that the transparent portion is not necessarily colorless and transparent; it may have a certain color, such as white, to soften the light.

[0602] In some optional embodiments, the transparent portion is configured to be colorless and transparent, which can better emit light outward and avoid the temperature rise in the enclosed space due to the absorption of too much emitted light.

[0603] In some optional embodiments, the projections of the first lighting assembly and the second lighting assembly in the vehicle's longitudinal direction coincide with the projection of the transparent portion in the same direction. That is, the transparent portion is at least partially located directly in front of the first lighting assembly and the second lighting assembly, in order to ensure that the lighting can effectively produce a lighting effect directly forward.

[0604] In particular, the transparent portion is located at least partially in front of the third lighting assembly to ensure that the third lighting assembly can effectively emit light forward, thereby improving the vehicle's visibility.

[0605] In some optional embodiments, the front cover and the rear cover are connected to form a sealed space, within which the first lighting assembly, the second lighting assembly, and the third lighting assembly are located. That is, the aforementioned first region 34, second region 35, and third region 36 all belong to the sealed space, preventing external moisture from entering and thus preventing short circuits and other problems for the internal LED units, thereby improving the product's lifespan.

[0606] In some optional embodiments, the assembly process of the front cover and the rear cover is one or more of ultrasonic welding or fasteners combined with elastic strips or sealant, thereby achieving a seal between the front and rear covers. When the surfaces of the front and rear covers that meet each other are relatively complex, the cost of elastic strips (i.e., sealant strips) and ultrasonic welding is relatively high. In this case, sealant is generally used for sealing, that is, fastening is done with fasteners such as bolts and clips, and sealant is applied to the connection. Once the sealant has cured, an effective seal can be achieved.

[0607] In some optional embodiments, the multi-functional work vehicle includes a headlight base 31 and a headlight cover 32 connected to the frame 1 and cooperating with each other to form a closed space. The lighting components and daytime running lights 318 are disposed in the closed space. The headlight cover 32 is at least partially configured as a transparent part, and light in the closed space can be irradiated to the outside through the transparent part.

[0608] Furthermore, in one of the optional embodiments, referring to Figure 2, the aforementioned enclosed space includes a left accommodating space 312 and a right accommodating space 311 that are interconnected, with a left lighting lamp 317 disposed in the left accommodating space 312 and a right lighting lamp 316 located in the right accommodating space 311.

[0609] As described above, the headlight cover 32 and the headlight socket 31 are sealed together. In some optional embodiments, the headlight cover 32 and the headlight socket 31 are sealed using one or more of ultrasonic welding, friction welding, sealant, and elastic strips. It should be noted that the above are only the processes for achieving a seal between the two, and should not be limited to the connection achieved through these processes. For example, in a more specific embodiment, the headlight cover 32 and the headlight socket 31 are sealed with sealant, but their relative positions need to be fixed using fasteners or bolts. Then, the gap between them is filled with sealant to maintain a sealed connection. Referring to Figures 2, 3, and 18, the headlight socket 31 is provided with a protrusion 314, and the headlight cover 32 can be provided with a fastener 321 that mates with the protrusion 314. The fastener 321 and the protrusion 314 cooperate to achieve the initial positioning of the headlight socket 31 and the headlight cover 32.

[0610] Referring to Figure 19, the headlight assembly 3 includes a headlight base 31 and a headlight cover 32. Referring to Figure 2, which is a schematic diagram of the headlight assembly 3 shown in Figure 19 without the headlight cover 32, the headlight base 31 is provided with a vent hole 3131. Referring to Figures 16 and 17, in some optional embodiments, the headlight base 31 includes a venting device 313, which includes a vent hole 3131. The vent hole 3131 can balance the pressure inside and outside the sealed space, preventing the pressure from increasing significantly due to the temperature rise inside the sealed space, thus avoiding damage to the sealing effect. Referring to Figure 17, which is a partially enlarged schematic diagram of Figure 16, the headlight base 31 is provided with a wire 315 for supplying power to the headlight base 31, and the wire 315 is sealed with sealant.

[0611] In one of the optional embodiments, a breathable membrane 3132 is provided at the vent 3131. The breathable membrane 3132 has a waterproof and breathable effect, preventing external moisture from entering the enclosed space and affecting the lighting components, while also ensuring breathability.

[0612] In one of the optional embodiments, referring to Figures 11 and 16, the front lamp 3 includes a left lamp 317 and a right lamp 316, and the vent 3131 includes a left vent and a right vent located behind the left lamp 317 and the right lamp 316, respectively.

[0613] In some optional embodiments, referring to Figure 16, the headlight unit 3 further includes a daytime running light 318 disposed in a sealed space and located between the left headlight 317 and the right headlight 316, and the vent 3131 further includes a central vent located behind the daytime running light 35.

[0614] In order to maintain a good airtightness in the sealed space of the headlight assembly, waterproof and breathable devices 313 are provided at the left vent, right vent, and middle vent.

[0615] In some optional embodiments, the porosity of the breathable membrane 3132 is 20% to 90%. In this embodiment, the heat generated by the lighting component will not be excessive, nor will it cause the air in the enclosed space to expand too significantly. Therefore, the porosity requirement for the breathable membrane 3132 is not high; generally, a breathable membrane 3132 with a porosity greater than 20% is sufficient to meet the requirements. However, a higher porosity will inevitably allow for faster air exchange, and thus is also within the range of options in this embodiment. Generally, a breathable membrane 3132 with a porosity not exceeding 90% is selected.

[0616] The area of ​​one side of the breathable membrane 3132 at a single vent 3131 is 20 mm². 2 ~400mm 2 As mentioned above, the heat generated by the lighting components will not be excessive, nor will it cause significant expansion of the air in the enclosed space. However, prolonged operation of the lighting components will still create a certain temperature difference between the inside and outside of the enclosed space. Therefore, when selecting a breathable membrane 3132 with low porosity, a larger area of ​​breathable membrane 3132 is generally required; conversely, when selecting a breathable membrane 3132 with high porosity, a slightly smaller area of ​​breathable membrane 3132 is generally sufficient to meet the ventilation requirements. Overall, for breathable membranes 3132 with porosity of 20% to 90%, this embodiment can select a single-sided area of ​​20 mm². 2 ~400mm 2 A breathable membrane 3132 is sufficient. Alternatively, the area of ​​a single breathable membrane 3132 can be appropriately reduced by configuring multiple breathable membranes 3132 and breathable holes 3131.

[0617] It should be noted that the breathable membrane 3132 is generally installed by gluing, that is, glue is applied to the edge of the breathable membrane 3132 to stick it to the edge of the vent 3131. However, the part of the breathable membrane 3132 covered with glue cannot maintain the breathability effect, that is, the effective breathable area of ​​the breathable membrane 3132 is smaller than its single-sided area.

[0618] In some optional embodiments, the area ratio of at least one of the breathable membranes 3132 to the area of ​​the corresponding vent 3131 is 2 to 8. As mentioned above, since the portion of the breathable membrane 3132 coated with adhesive cannot maintain breathability, and considering that the waterproof breathable membrane 3132 needs to have good breathability and be relatively firmly adhered to the vent 3131, the area ratio of the waterproof breathable membrane 3132 to the vent 3131 generally meets a ratio of 1.5 to 10. For example, in one specific embodiment, the waterproof breathable membrane 3132 is a circular sheet with a radius of 4 mm, and the vent 3131 is a circular hole with a diameter of 2 mm, then the area ratio of the two is 4. In another specific embodiment, the waterproof breathable membrane 3132 is a circular sheet with a radius of 6 mm, and the vent 3131 is a circular hole with a diameter of 4 mm, then the area ratio of the two is 2.25. In another specific embodiment, the waterproof and breathable membrane 3132 is a circular sheet with a radius of 8 mm, and the vent 3131 is a circular hole with a diameter of 3 mm. Therefore, the area ratio of the two is approximately 7.1. In summary, the area ratio of the two roughly conforms to the range of 2 to 8 mentioned above.

[0619] In one of the optional embodiments, referring to Figure 17, a mounting groove is provided on the rear lamp cover 73, and the vent 3131 and the breathable membrane 3132 are both disposed within the mounting groove, with the outer edge of the breathable membrane 3132 not exceeding the groove wall. This prevents displacement of the breathable membrane 3132 due to contact with the side wall when external wind forces or objects slide along the outer wall of the rear lamp cover 73, and further ensures the stability of the breathable membrane 3132's position, thus guaranteeing its good waterproof and breathable effect.

[0620] Referring to Figures 16 and 17, in some optional embodiments, since the lighting lamp and the headlight controller are components that generate a significant amount of heat in a confined space, the positions of the lamp holder 31 corresponding to the left lighting lamp 317, the right lighting lamp 316, and the headlight controller are all provided with ventilation holes 3131. Each ventilation hole 3131 is provided with one or more ventilation membranes 3132. The specific pore diameter of the ventilation hole 3131, the size of the ventilation membrane 3132, and the porosity of the ventilation membrane 3132 can be selected with reference to the above-disclosed information.

[0621] In some optional embodiments, the sealed space formed by the aforementioned front cover, thick cover, and waterproof and breathable device 313 meets at least an IPX5 waterproof rating. It should be further noted that the IP (Ingress Protection) rating system is used to classify electrical appliances according to their dustproof and moisture-proof characteristics; the IP protection rating consists of two numbers. The first number indicates the level of dustproof protection and prevention of foreign object intrusion. The second number indicates the degree of moisture and water immersion protection; the higher the number, the higher the protection level. In this embodiment, the IPX5 waterproof rating means that it can withstand low-pressure water jets and a 6.3mm inner diameter water jet from the nozzle. Meeting this waterproof rating ensures that the headlight assembly can operate normally in rainy weather without water ingress into the lampshade or other abnormal operating conditions.

[0622] Furthermore, in another optional embodiment, the aforementioned sealed space meets an IPX6 waterproof rating. The second digit, 6, indicates that the sealed space is capable of withstanding a powerful water jet with an inner diameter of 12.5mm ejected from the nozzle. This further prevents water from entering the lamp cover and affecting the lifespan of the lighting fixture when the garden vehicle is operating in rainy weather.

[0623] Furthermore, in another optional embodiment, the aforementioned enclosed space meets an IPX7 waterproof rating. The second digit, 7, indicates that the enclosed space provides protection against temporary immersion and can withstand submersion in water for a specified time and pressure. This further prevents water from entering the lampshade of garden vehicles during rainy weather, thus reducing the lifespan of the lighting fixtures.

[0624] In one of the optional embodiments, referring to Figure 17, the rear cover has a cable outlet. The first and / or second and / or third lighting components are coupled to the ride-on lawnmower via a wire 315 passing through the cable outlet. The connection between the cable outlet and the wire 315 is sealed by filling with sealant. Further, a hot-melt sealant is selected. During manufacturing, applying hot-melt sealant along the contact surfaces of the headlight cover and headlight holder is less difficult and reduces production costs.

[0625] In some optional embodiments, the front cover and the rear cover are respectively provided with a first fastener and a second fastener, at least one of the first fastener and the second fastener being elastic. The first fastener and the second fastener cooperate to fix the front cover to the rear cover. The combination of the first fastener and the second fastener is used for initial positioning of the front cover and the rear cover, wherein the first fastener and / or the second fastener are elastic to facilitate installation, and after installation, the two fasteners elastically abut against each other to produce a certain sealing effect.

[0626] Furthermore, in some optional embodiments, referring to Figures 16, 17, 18, and 19, the first fastener is configured as a protrusion 314 fixed to the rear cover, and the second fastener is configured as a latch 321 fixed to the front cover. The latch 321 has a latching space for accommodating the protrusion 314, and the protrusion is accommodated within the latching space when the front and rear covers are engaged. The front and rear covers engage to form the structure shown in Figure 19.

[0627] Furthermore, in some optional embodiments, after the first, second, and third lighting components are electrically connected to each other, one of the lighting components is connected to the vehicle controller via a wire 315 passing through the outlet, facilitating control of the headlights. In this embodiment, only one outlet is required. In other optional embodiments, the first, second, and third lighting components are each connected to the vehicle controller (not shown in the figure) via wires 315 passing through the outlets. In this embodiment, one, two, or three outlets can be configured; correspondingly, each outlet needs to be filled with sealant to achieve a seal.

[0628] In some embodiments described herein, by configuring a vent hole and a waterproof and breathable device on the headlight mount, the lighting lamp is placed in a waterproof and breathable sealed space, preventing external moisture from entering the sealed space and affecting the lifespan of the lighting lamp, while also ensuring breathability.

[0629] In some optional embodiments, referring to Figure 2, the left headlight 317, right headlight 316, and daytime running light 318 all belong to the front lamp unit 3. Further, the front lamp unit 3 includes a headlight cover 32 and a headlight base 31 that cooperate to form an accommodating space, and the left headlight 317, right headlight 316, and daytime running light 318 are all located within this accommodating space. As described above, this accommodating space is a closed space, and the closed space includes a left accommodating space 312 and a right accommodating space 311 that are interconnected. The left headlight 317 is disposed in the left accommodating space 312, and the right headlight 316 is disposed in the right accommodating space 311.

[0630] In some optional embodiments, the enclosed space further includes a central accommodating space located between the left accommodating space 312 and the right accommodating space 311. The central lamp panel 3181 is disposed in the central accommodating space, which connects to the left accommodating space 312 and the right accommodating space 311. As mentioned above, the interconnection of the three accommodating spaces allows the daytime running light 318 to be closer to the left illumination light 317 and the right illumination light 316. When the second LED in the left illumination light 317 and / or the right illumination light 316 works in conjunction with the first LED 31811 to achieve the lighting effect, the closer distance allows the user to experience a more continuous lighting effect and a better sensory experience.

[0631] In some optional embodiments, the integrated headlight assembly further includes a headlight controller that controls at least one of the first, second, and third lighting components. This headlight controller is connected to the vehicle controller of the ride-on lawnmower via a signal connection based on a control protocol. Each lighting component in the integrated headlight assembly should be controlled by the vehicle controller, such as individually controlling the brightness and circuit switching of the LED units of some lighting components, thus achieving more flexible control over the vehicle lights.

[0632] In one of the optional embodiments, a headlight controller (not shown) for controlling the operation of the lighting components is arranged in the enclosed space, and a vehicle controller (not shown) coupled to the headlight controller is arranged in the frame 1. The headlight controller can control the lighting components, specifically such as controlling the opening and closing, brightness, etc. of each light-emitting unit in the left headlight 317 and / or the right headlight 316.

[0633] The vehicle controller is connected to the vehicle's power supply and can control the overall power supply of the headlight assembly; it can also send control signals to the headlight controller to convey the user / vehicle control system's expectations for the lighting assembly's performance. In some optional embodiments, the multi-functional work vehicle includes a battery compartment 6 located at the rear of the vehicle, and the power supply includes at least a battery located within the battery compartment 6.

[0634] In some optional embodiments, referring to Figures 2, 3, and 13, viewed from the front-rear direction, neither the left headlight 317 nor the right headlight 316 overlaps with the daytime running lights 318. Furthermore, the distance between the reflector of the left headlight 317 or the right headlight 316 and the nearest first LED 31811 along the second direction is 10mm to 100mm, which corresponds to the dimension L1 of 10mm to 100mm in Figure 13. Looking at the headlights from the front, the visual effect is that the headlight light is emitted forward from the reflector; the daytime running lights 318 emit light forward from the first LED 31811. The closer distance between the first LED 31811 and the reflector makes the light appear more continuous, exhibiting a continuous light effect with a strong visual impact. The aforementioned spacing of 10mm to 100mm is sufficient to achieve this continuous light effect. Furthermore, in some optional embodiments, the distance between the reflective tile and the nearest first LED chip 31811 along the second direction is 10mm to 40mm. This smaller spacing results in a stronger visual continuity effect and better through-type lighting.

[0635] Referring to Figures 9 and 14, in some optional embodiments, to simplify assembly, the left light 317 and / or the right light 316 include light-emitting panels. Specifically, the left light 317 includes a left light-emitting panel 3171, and the right light 316 includes a right light-emitting panel 3161, with the lighting bulbs disposed on the light-emitting panels. Referring to Figure 14, the left light-emitting panel 3171 is not parallel to the right light-emitting panel 3161. In some optional embodiments, both light-emitting panels are tilted towards the center in the left-right direction, i.e., the light-emitting panels are tilted to illuminate the center, resulting in a slight tilt angle that concentrates the light towards the center. This facilitates the overlap of the light from the two lights in front of the vehicle for a stronger lighting effect.

[0636] In some optional embodiments, the illumination beads are located on the upper or lower wall of the corresponding light-emitting plate. Referring to Figure 15, the angle between the light-emitting plate and the ground is 0° to 20°, that is, β in the figure is greater than 0° and less than or equal to 20°. In other words, the reflector is located above or below the illumination beads, and the illumination beads emit light towards the reflector. Because the illumination beads do not occupy the dimensions of the reflector in the vehicle's longitudinal direction, a deeper reflector can be configured within the limited space for the lighting fixture, thus giving the reflector a stronger light-focusing effect. Conversely, for the same light-focusing effect, the technical solution where the illumination beads do not occupy the longitudinal direction also facilitates reducing the longitudinal dimension of the lighting fixture's space, thereby reducing the total space of the headlights and facilitating the overall spatial arrangement of the vehicle.

[0637] In one of the optional embodiments, the lighting beads are located on the upper wall of the light-emitting panel, and the lighting beads emit light toward the reflector above them. The reflector is located above the lighting beads, and the light-emitting panel reflects the light to create a focusing effect and direct it toward the front of the vehicle.

[0638] Referring to Figure 9, in another optional embodiment, the illumination bulbs are located on the lower wall of the light-emitting panel, emitting light towards the reflector below them. The reflector is located below the illumination bulbs, and the reflection from the reflector focuses the light towards the front of the vehicle. Furthermore, because the light-emitting panel emits light downwards, and the headlights are positioned closer to the vehicle frame 1 vertically (below the user's head), the illumination bulbs are not visible to the user when standing normally; only the reflector is visible, resulting in a better overall visual experience.

[0639] In some optional embodiments, the angle β between the light-emitting panel and the ground is 0° to 20°. This small angle does not result in it occupying a large vertical space, and its tilt angle has the technical effect described above: the light is tilted towards the center so that the lights of the left lighting lamp 317 and the right lighting lamp 316 can overlap in front, thereby enhancing the lighting effect. In some optional embodiments, the angle between the light-emitting panel and the ground is 2° to 6°, that is, β is greater than 2° and less than or equal to 6°. This smaller angle can achieve the above-mentioned technical effect, and it occupies less vertical space, making it easier to arrange in space. Furthermore, in one embodiment, the angle between the light-emitting panel and the ground is 4°.

[0640] As mentioned earlier, at least a portion of the headlight cover 32 is configured as a transparent portion. It should be noted that the transparent portion is not necessarily colorless and transparent; some parts of it may have a certain color, such as white, to make the light softer.

[0641] In some optional embodiments, the transparent portion is configured to be colorless and transparent, which can better emit light outward and avoid the temperature rise in the enclosed space due to the absorption of too much emitted light.

[0642] In some optional embodiments, the projections of the left lamp 317 and the right lamp 316 in the first direction coincide with the projection of the transparent portion in the first direction. That is, the transparent portion is at least partially located directly in front of the left lamp 317 and the right lamp 316, in order to ensure that the lamps can effectively produce a lighting effect in front.

[0643] Specifically, the transparent portion is located at least partially in front of the daytime running light 318 to ensure that the daytime running light 318 can effectively emit light forward to improve the vehicle's visibility.

[0644] In some optional embodiments, in order to ensure that the light emitted by the lighting components is not blocked by the front lamp cover 32, the projections of the left lamp 317 and the right lamp 316 in the first direction are located within the projection of the transparent portion in the first direction. That is, in this embodiment, the front of the left lamp 317 and the right lamp 316 must be the transparent portion of the front lamp cover 32, so as to reduce the obstruction of the lighting light by the front lamp cover 32.

[0645] In some optional embodiments, the left headlight 317 and right headlight 316 do not only emit light directly forward, but also have a certain extended illumination angle. That is, the left headlight 317 and right headlight 316 have a certain beam angle, so that the vehicle can not only illuminate the area directly in front of the headlights, but also illuminate the area slightly to the side in front of the vehicle. In this embodiment, the headlights have a beam angle of 120°, that is, angle α in Figure 8 is 120°. It should be further explained that this beam angle does not contradict the aforementioned strong light intensity at 10 meters in front. This beam angle indicates that the headlights can provide certain illumination within the range of this beam angle, and it does not have a strong light effect near the edge of the beam angle.

[0646] In some optional embodiments, the lighting lamp has a beam angle of 160°, i.e., the α angle shown in Figure 8 is 160°.

[0647] In some optional embodiments, the entire headlight cover 32 is configured as a colorless transparent portion, manufactured using a one-piece injection molding process, which completely does not obstruct the light emitted by the headlight. When the user is in front of the vehicle, the completely transparent material of the headlight cover 32 provides better visibility.

[0648] In some optional embodiments, the headlight cover 32 is not configured as a colorless transparent part as a whole. Its edges or other parts that do not block the light of the headlight are made of a material that is similar to or gradually changes color with the body, which can also produce a similar lighting effect.

[0649] The projection of the daytime running light 318 in the first direction is located within the projection of the transparent portion in the first direction, in order to reduce the obstruction of the lighting light by the headlight cover 32.

[0650] In some optional embodiments, the ratio of the dimensions of the daytime running light 318 to the transparent portion in the second direction is 0.2 to 1. As mentioned above, the ratio of the dimensions of the daytime running light 318 to the dimensions of the vehicle frame 1 in the second direction is 0.2 to 1. In embodiments where the headlight cover 32 is entirely configured as a transparent portion, the width of the headlight cover 32 and the width of the vehicle frame 1 can be approximately equal, therefore the ratio of the dimensions of the daytime running light 318 to the transparent portion can be approximately equal to the ratio of the dimensions of the daytime running light 318 to the dimensions of the vehicle frame 1. That is, the ratio of the dimensions of the daytime running light 318 to the transparent portion in the second direction is 0.2 to 1.

[0651] In some optional embodiments, the ratio of the transparent portion of the headlight cover 32 to the dimension of the frame 1 in the second direction is 0.2 to 1.5.

[0652] For vehicles used in outdoor operations, the width of the frame 1 is not uniform. The width of the frame 1 is generally 500mm to 2000mm. For the headlights that provide illumination at the front of the vehicle, especially the headlights in this application where the left headlight 317 and the right headlight 316 are configured together in a closed space, the relatively preferred width range of the headlights is not significantly wider than the frame 1.

[0653] For work vehicles with a slightly wider frame (1), although the body panels will occupy a certain width, the body will not be significantly wider than the frame (1) in proportion, as the frame (1) itself is also relatively wide. Otherwise, it would affect the vehicle's passability in the width direction. However, it should not be too narrow in the width direction either, otherwise it would not meet the requirement of simultaneously equipping left and right headlights. That is, the headlights can be slightly wider or slightly narrower than the frame (1). This type of vehicle is generally a work vehicle that can carry two or more people laterally.

[0654] However, for some outdoor work vehicles that are relatively narrow, the total width of the vehicle body will be significantly wider than the frame 1 due to the presence of the side panels. In this case, the headlights being slightly wider than the body will not significantly affect the vehicle's passability in the width direction.

[0655] Example optional frame 1, headlight width as follows:

[0656] The frame 1 is 2000mm wide, and the headlight is 600mm, 1600mm, or 2200mm wide. The corresponding ratios of the headlight to the frame 1 in the second direction (i.e., the width ratio) are 0.3, 0.8, and 1.1, respectively.

[0657] The frame 1 is 1600mm wide, and the headlight is 700mm, 1100mm, or 1600mm wide. The corresponding ratios of the headlight to the frame 1 in the second direction (i.e., the width ratio) are 0.4, 0.7, and 1.0, respectively.

[0658] The frame 1 is 1200mm wide, and the headlight is 800mm, 1200mm, or 1400mm wide. The corresponding ratios of the headlight to the frame 1 in the second direction (i.e., the width ratio) are 0.7, 1.0, and 1.2, respectively.

[0659] The frame 1 is 800mm wide, and the headlight is 500mm, 800mm, or 1100mm wide. The corresponding ratios of the headlight to the frame 1 in the second direction (i.e., the width ratio) are 0.6, 1.0, and 1.4, respectively.

[0660] The frame 1 is 500mm wide. Due to the presence of the left and right cover parts, the width of the vehicle body is approximately 650-750mm. The headlight can be 350mm, 500mm, or 750mm wide, which correspond to the ratio of the headlight to the frame 1 in the second direction (i.e., the width ratio) as follows: 0.7, 1.0, and 1.5, respectively.

[0661] All the above ratios are rounded to one decimal place.

[0662] In some optional embodiments, the headlight cover 32 and the headlight socket 31 together form the headlight (i.e., headlight portion 3) at the front of the vehicle. The width of the headlight cover 32 is not significantly different from the width of the headlight. For embodiments where the headlight cover 32 is entirely made of transparent material, the ratio of the dimensions of the headlight to the frame 1 in the second direction (i.e., the width ratio) is also the ratio of the headlight cover 32 to the frame 1. For embodiments where a portion of the headlight cover 32 is made of transparent material, the ratio of the dimensions of the headlight cover 32 to the frame 1 in the second direction should be slightly smaller than the above ratio, but should not have a large difference. Overall, a ratio of the dimensions of the transparent portion to the frame 1 in the second direction of 0.2 to 1.5 can cover most embodiments applicable to this method.

[0663] In one embodiment, referring to Figures 20 and 21, B in Figure 20 represents the width of the frame 1, and A in Figure 21 represents the width of the transparent portion. That is, the ratio of A to B ranges from 0.2 to 1.5.

[0664] In some optional embodiments, the outdoor work component is configured to be connected to a cutter 4 on the frame 1, the cutter 4 being used to perform grass-cutting actions, and the outdoor work vehicle is a garden work vehicle with grass-cutting function, especially a grass-cutting vehicle.

[0665] In the existing technology, the cutting width of the mainstream cutting platform 4 ranges from 30 inches to 72 inches. Common cutting platforms 4 include 30 inches, 42 inches, 50 inches, 54 inches, 60 inches, and 72 inches. The width of the cutting platform 4 itself is slightly larger than the cutting width, but the difference is not significant. That is, the approximate width range of the cutting platform 4 is 760mm to 1830mm. A frame 1 of the same width can be configured with various sizes of cutting platforms 4, but generally, the width of the cutting platform 4 will not be significantly larger than the width of the frame 1, otherwise the lateral stability of the vehicle may be affected. In other words, generally, a cutting platform 4 with a width smaller than the vehicle body width or a width slightly larger than the vehicle body width is selected.

[0666] Examples of choices are as follows:

[0667] The frame 1 is 2000mm wide, the headlight is 600mm, 1800mm, or 2200mm wide, and the cutter 4 is 1270mm, 1520mm, or 1830mm wide. The ratio of the headlight to the cutter 4 in the second direction (i.e., the width ratio) is approximately 0.3 to 1.7.

[0668] The frame 1 is 1600mm wide, the headlight is 700mm, 1100mm, or 1600mm wide, and the cutter 4 is 1010mm, 1520mm, or 1830mm wide. The corresponding ratios of the headlight and the cutter 4 in the second direction (i.e., the width ratio) are 0.4 to 1.6, respectively.

[0669] The frame 1 is 1200mm wide, the headlight is 800mm, 1200mm, or 1400mm wide, and the cutter 4 is 760mm, 1010mm, or 1370mm wide. The ratio of the headlight to the cutter 4 in the second direction (i.e., the width ratio) is 0.6 to 1.8, respectively.

[0670] The frame 1 is 800mm wide, the headlight is 600mm, 800mm, or 1100mm wide, and the cutter 4 is 760mm, 1010mm, or 1270mm wide. The ratio of the headlight to the cutter 4 in the second direction (i.e., the width ratio) is 0.5 to 1.4, respectively.

[0671] The frame 1 is 500mm wide. Due to the presence of the left and right cover parts, the width of the vehicle body is approximately 650-750mm. The headlight can be 350mm, 650mm, or 800mm wide. The cutter 4 is 760mm, 1010mm, or 1270mm wide. The ratio of the headlight to the cutter 4 in the second direction (i.e., the width ratio) is 0.3 to 1.1, respectively.

[0672] All the above ratios are rounded to one decimal place.

[0673] In summary, for the embodiment using the headlight described in this application, the ratio of the headlight's dimensions to the cutter 4 in the second direction is approximately 0.3 to 1.8. The width of the headlight cover 32 is not significantly different from the width of the headlight, meaning the ratio of the width of the headlight cover 32 to the width of the cutter 4 in the second direction is also approximately 0.3 to 1.8. This is particularly true for embodiments where the headlight cover 32 is entirely transparent; in these embodiments, the ratio of the width of the transparent portion to the width of the cutter 4 in the second direction is approximately 0.3 to 1.8.

[0674] In one embodiment, referring to Figures 20 and 21, D in Figure 20 represents the width of the cutting platform 4, and A in Figure 21 represents the width of the transparent portion. That is, the range of A / B is 0.3 to 1.8.

[0675] Referring to Figures 1, 22, 23, and 24, in some optional embodiments, the multi-functional work vehicle further includes a taillight 7 disposed at the rear of the vehicle, the taillight 7 being configured in a strip shape. At least a portion of the taillight 7 can emit red light, making it easier for personnel located behind to clearly observe the presence of the work vehicle.

[0676] Furthermore, referring to Figures 22, 23, 24, 25, and 26, the taillight 7 further includes a rear lamp holder 71, a rear lamp cover 73, and a rear lamp strip 72. The rear lamp strip 72 has taillight beads 721 arranged in an array, which can emit light under controlled conditions. The rear lamp holder 71 and the rear lamp cover 73 together form a sealed rear receiving space, and the rear lamp strip 72 is disposed in the rear receiving space. The sealed rear receiving space can prevent external water droplets from entering and affecting the operation of the rear lamp strip 72.

[0677] Furthermore, referring to Figure 24, in one of the alternative embodiments, the taillight 7 is disposed within the housing of the battery compartment 6.

[0678] In some optional embodiments, the rear light cover 73 is unobstructed in the direction of the taillight 7's illumination, meaning the rear light cover 73 is not obstructed and therefore does not create a segmented display effect. The overall lighting effect of the taillights presents a continuous strip shape, making it more eye-catching.

[0679] In one optional embodiment, referring to Figure 25, the rear light strip 72 is configured as a plurality of strips, at least two of which face different directions. The rear light strip 72 illuminates not only the area directly behind the vehicle, but also at least one side rear. In another optional embodiment, the rear light strip 72 is configured as three strip segments connected end-to-end, with two strip segments facing the two side rear respectively, and the middle strip segment illuminating the area directly behind. This ensures that when personnel are located directly behind or to the side rear of the vehicle, the presence of the working vehicle can be clearly identified by the taillights 7.

[0680] The taillight 7 is positioned at the rear of the vehicle. In some optional embodiments, a rear cover fixed to the frame 1 is generally provided at the rear of the vehicle, and the taillight 7 is positioned on the surface of the rear cover. In this case, the rear cover is slightly larger than the frame 1 in the second direction, and the taillight 7 is also necessarily larger than the frame 1 in the second direction.

[0681] In some specific optional embodiments, the frame 1 is 500mm wide, the rear cover is 650mm wide, and the taillight 7 is 680mm wide. In this case, the ratio of the taillight 7 to the frame 1 in the second direction is 1.4. Clearly, in this embodiment, the size of the taillight 7 can be reduced by decreasing the size of the rear cover. Therefore, in embodiments where the taillight 7 is positioned on the rear cover covering the frame 1, the ratio of the taillight 7 to the frame 1 in the second direction is 1 to 1.4.

[0682] In another optional embodiment, the rear of the vehicle is provided with a frame cover that only covers the frame 1. A box-shaped structure is also provided on the frame 1. In order to reduce the probability of the box-shaped structure being directly hit by the outside world, the size of the box-shaped structure is slightly smaller than the frame 1. The taillight 7 is disposed on the surface of the box-shaped structure.

[0683] In some specific optional embodiments, the frame 1 is 500mm wide, the rear cover is 650mm wide, and the battery compartment 6 is 400mm wide. That is, in the second direction, a 50mm gap is reserved on both sides of the battery compartment 6 to prevent it from being impacted. In this embodiment, the taillight 7 can be embedded in the outer wall of the battery compartment 6 so that it does not protrude significantly from the battery compartment 6. In this case, the taillight 7 is approximately 400mm wide, and the ratio of the taillight 7 to the frame 1 in the second direction is 0.8. Obviously, the size of the battery compartment 6 in this embodiment can be appropriately enlarged because there is a buffer gap between the battery inside the battery compartment 6 and the outer wall of the battery compartment 6. Therefore, the width of the taillight 7 can be configured to be equal to or slightly greater than the width of the frame 1. Thus, in the above embodiment where the battery compartment 6 is narrower than the frame 1 and the taillight 7 is disposed on the outer wall of the battery compartment 6, the ratio of the taillight 7 to the frame 1 in the second direction is 0.8 to 1.

[0684] In one specific alternative embodiment, the box-like structure at the rear of the vehicle is a battery compartment 6, which houses a battery for supplying power to the vehicle. As mentioned above, in order to reduce the probability of battery damage due to collision, the outer wall of the battery compartment 6 does not extend beyond the frame 1 in the lateral direction. In this embodiment, the taillight 7 disposed on the outer wall of the battery compartment 6 is not larger than the frame 1 in the second direction, or only the taillight 7 protrudes from the frame 1.

[0685] In another optional embodiment, the upper part of the battery compartment 6 is smaller. In this case, the taillight 7 is placed on the battery compartment 6, resulting in the taillight 7 being smaller in the second direction. It is worth further explaining that the taillight 7 is relatively narrow at this time, but it can still present the aforementioned strip shape and partial orientation to the left and right sides.

[0686] Examples of choices are as follows:

[0687] The frame 1 is 2000mm wide, and the taillight 7 is 400mm, 700mm, or 1200mm wide. At this time, the ratio of the taillight 7 to the frame 1 in the second direction is 0.2 to 0.6.

[0688] The frame 1 is 1200mm wide, and the taillight 7 is 400mm, 600mm, or 800mm wide. At this time, the ratio of the taillight 7 to the frame 1 in the second direction is 0.3 to 0.7.

[0689] The frame 1 is 500mm wide, and the taillight 7 is 150mm, 250mm, or 300mm wide. At this time, the ratio of the taillight 7 to the frame 1 in the second direction is 0.3 to 0.6.

[0690] In summary, it can be seen that the range of options for taillight 7 is relatively wider. For different technical solutions, the ratio of the dimensions of taillight 7 to the frame 1 in the second direction varies greatly, but is roughly in the range of 0.2 to 1.4.

[0691] In one embodiment, referring to Figures 20, 22, and 23, B in Figure 20 represents the width of the frame 1, and C in Figure 23 represents the width of the taillight 7. That is, the range of C / B is 0.2 to 1.4.

[0692] The ratio of the dimensions of the headlight to the taillight 7 in the second direction, and the ratio of the dimensions of the taillight 7 to the cutter 4 in the second direction, can be obtained by referring to the above calculation method:

[0693] Examples of choices are as follows:

[0694] The frame 1 is 2000mm wide, the headlight is 600mm, 1800mm, or 2200mm wide, the taillight 7 is 400mm, 1200mm, or 2200mm wide, the cutter 4 is 1270mm, 1520mm, or 1830mm wide, the ratio of the headlight to the taillight 7 in the second direction is approximately 0.3 to 5.5, and the ratio of the taillight 7 to the cutter 4 in the second direction is approximately 0.2 to 1.7.

[0695] The frame 1 is 1600mm wide, the headlight is 700mm, 1100mm, or 1600mm wide, the taillight 7 is 600mm, 1100mm, or 1650mm wide, the cutter 4 is 1010mm, 1520mm, or 1830mm wide, the ratio of the headlight to the taillight 7 in the second direction is approximately 0.4 to 2.7, and the ratio of the taillight 7 to the cutter 4 in the second direction is approximately 0.3 to 1.6.

[0696] The frame 1 is 1200mm wide, the headlight is 800mm, 1200mm, or 1400mm wide, the taillight 7 is 500mm, 850mm, or 1250mm wide, the cutter 4 is 760mm, 1010mm, or 1370mm wide, the ratio of the headlight to the taillight 7 in the second direction is approximately 0.5 to 2.8, and the ratio of the taillight 7 to the cutter 4 in the second direction is approximately 0.4 to 1.6.

[0697] The frame 1 is 800mm wide, the headlight is 600mm, 800mm, or 1100mm wide, the taillight 7 is 350mm, 600mm, or 900mm wide, the cutter 4 is 760mm, 1010mm, or 1270mm wide, the ratio of the headlight to the taillight 7 in the second direction is approximately 0.5 to 3.0, and the ratio of the taillight 7 to the cutter 4 in the second direction is approximately 0.3 to 1.2.

[0698] The frame 1 is 500mm wide. Due to the presence of the left and right cover panels, the width of the vehicle body is approximately 650-750mm. The width of the headlight can be selected as 350mm, 650mm, or 800mm. The width of the taillight 7 is 200mm, 400mm, or 730mm. The width of the cutter 4 is 760mm, 1010mm, or 1270mm. The ratio of the dimensions of the headlight to the taillight 7 in the second direction is approximately 0.2 to 4. The ratio of the dimensions of the taillight 7 to the cutter 4 in the second direction is approximately 0.2 to 1.0.

[0699] All the above ratios are rounded to one decimal place.

[0700] As mentioned earlier, the headlight cover 32 is configured as an integral transparent part, meaning that the size of the transparent part in the second direction is equal to that of the headlight cover 32, and approximately equal to the approximate size of the headlight. Therefore, in summary, the approximate range of the ratio of the size of the transparent part to that of the taillight 7 in the second direction is 0.2 to 5.5; and the approximate range of the ratio of the size of the taillight 7 to that of the cutter 4 in the second direction is 0.2 to 1.7.

[0701] In one embodiment, referring to Figures 20, 21, 22, and 23, D in Figure 20 represents the width of the cutter 4, A in Figure 21 represents the width of the transparent portion, and C in Figure 23 represents the width of the taillight 7. That is, the range of A / C is 0.2 to 5.5; and the range of C / D is 0.2 to 1.7.

[0702] Referring to Figures 27 and 28, in some optional embodiments, the dimensions of the headlights in the vertical direction vary at different points along the second direction; that is, the dimensions of the headlights in the vertical direction are not uniform. The outer contour of the headlights in the vertical direction is approximately equal to that of the headlight cover 32. However, the taillights 7 are strips with relatively uniform dimensions in the vertical direction. Defined as 'a' for the maximum vertical dimension of the headlight cover 32 and 'd' for the maximum vertical dimension of the taillights 7, then a:d = 1 to 10. That is, in some optional embodiments, the width of the taillights 7 in the vertical direction is larger and equal to that of the headlight cover 32. In another optional embodiment, the width of the taillights 7 in the vertical direction is smaller and is one-tenth the width of the headlight cover 32. In yet another optional embodiment, the width of the taillights 7 in the vertical direction is moderate, greater than one-tenth the maximum dimension of the headlight cover 32 but less than the maximum vertical width of the headlight cover 32.

[0703] As mentioned above, the dimensions of the headlights in the vertical direction are not necessarily uniform, but the taillights 7 are strip-shaped with relatively uniform dimensions in the vertical direction. Here, we define the minimum dimension (b) of the portion of the headlight cover 32 used to house the display unit in the vertical direction as the taillight's maximum dimension (d), where b:d = 0.5–10. That is, in some optional embodiments, the taillight 7 has a larger vertical width, which is twice the minimum dimension of the headlight cover 32. In another optional embodiment, the taillight 7 has a smaller vertical width, which is one-tenth the minimum dimension of the headlight cover 32. In yet another optional embodiment, the taillight 7 has a moderate vertical width, greater than one-tenth the minimum dimension of the headlight cover 32 but less than twice the minimum vertical width of the headlight cover 32.

[0704] To further clarify: the preceding text did not abandon the protection scope of uniform vertical dimensions of all parts of the headlights. If the vertical dimensions of all parts of the headlights are uniform, then a = b in the preceding text.

[0705] In some optional embodiments, the length of the rear lamp cover 73 is greater than the length of the light-emitting strip, and the light-emitting strip is necessarily located inside the rear lamp cover 73. Therefore, there is no overlapping area between the light-emitting strips, which avoids one light-emitting strip blocking the light emitted by another light-emitting strip.

[0706] As previously stated, in some embodiments of the present invention, a daytime running light 318 is disposed within the headlight cover 32. In some optional embodiments, the ratio of the size of the daytime running light 318 to the size of the transparent portion in the second direction is 0.2 to 0.6. That is, the ratio of the sum of the sizes of the left headlight 317 and the right headlight 316 located on both sides of the daytime running light in the second direction to the size of the transparent portion in the second direction does not exceed 0.8. Since the daytime running light 318, the left headlight 317, and the right headlight 316 do not necessarily completely occupy the entire space of the transparent portion along the second direction, the minimum size occupied by the left headlight 317 and the right headlight 316 along the second direction should not be limited, and those skilled in the art can freely adjust it according to their needs.

[0707] In some optional embodiments, the daytime running light 318 includes an array of first LED beads 31811, the number of which is 20 to 500. More preferably, the first LED beads 31811 are selected as LED beads, each LED bead arranged in a rectangular array, with 18 to 30 beads per row and 2 to 5 rows. Further, to simplify the configuration of the first LED beads 31811, the daytime running light 318 also includes a central light plate 3181, in which the first LED beads 31811 are integrated.

[0708] Furthermore, to enable the rear light strip 72 to also display a rhythmic lighting effect, in some optional embodiments, the rear light strip 72 includes rear LED beads. The multi-functional work vehicle includes a rear light controller (not shown in the figure) for controlling the opening and closing of the rear LED beads in the rear light strip 72. The minimum number of rear LED beads that the rear light controller can illuminate at a time is two. That is, under the control of the rear light controller, at least two rear LED beads are simultaneously opened and closed. The at least two rear LED beads that are simultaneously opened and closed under the control of the rear light controller are defined as a rear rhythmic unit. The rear light controller can control each rhythmic unit to rhythmically move according to a set pattern, that is, to be lit or turned off according to a set pattern.

[0709] This embodiment discloses a multi-functional work vehicle. Referring to Figure 1, it includes a frame 1 and an outdoor work component. The frame 1 extends along a first direction, which is also the front-rear direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work.

[0710] The multi-functional work vehicle in this embodiment also includes a display component, which is disposed in the middle of the front side of the frame 1 and emits light towards the front of the vehicle; specifically, the display component includes a display unit, which is lit or turned off in a predetermined order when the vehicle is in different states, so as to improve the vehicle's visibility or display vehicle status information to the outside world.

[0711] In some optional embodiments, referring to Figures 2 and 3, the display element is configured as a plate.

[0712] In one of the optional embodiments, referring to Figures 1 and 2, the multi-functional work vehicle includes an outer lamp cover 2 disposed on the frame 1, and a headlight assembly (i.e., a headlight portion 3) is disposed within the outer lamp cover 2. Referring to Figure 4, the headlight assembly includes a headlight base 31 and a headlight cover 32, the headlight base 31 and the headlight cover 32 cooperating to form a receiving space for at least accommodating a display element, and the headlight cover 32 is configured as a transparent material at least directly in front of the display element.

[0713] In one specific optional embodiment, the display units of the display are arranged in an array along a second direction, and the multi-functional work vehicle further includes a left light 317 and a right light 316 located on both sides of the display along the second direction. Illumination bulbs are disposed within the left light 317 and right light 316, where the second direction is the width direction of the vehicle. When the display is turned on or off in a predetermined sequence, the illumination bulbs within the left light 317 and / or right light 316 are turned on or off in a predetermined sequence along with the display units of the display, thereby enhancing visibility or improving the effect of displaying vehicle status information.

[0714] In some optional embodiments, referring to Figures 4 and 5, the left light 317 and right light 316 are also arranged in the receiving space of the headlight assembly and are close to the display.

[0715] In one specific optional embodiment, the multi-functional work vehicle further includes a headlight controller for controlling the operation of the display units, and several adjacent display units form a group of rhythmic units; when the headlight controller controls the display units to operate, the operating status of the display units in the group of rhythmic units changes synchronously. Furthermore, when the multi-functional work vehicle is under manual control or its operating status changes, the headlight controller controls the display units to produce changes in lighting effects.

[0716] In one alternative embodiment, each group of rhythm units occupies approximately equal space in the display, so that when the lighting effect switches, the visual effect of the two rhythm units alternately lighting up is closer to the movement of a single rhythm unit.

[0717] In one specific alternative embodiment, referring to Figures 3, 29, and 30, the display element is configured as a daytime running light 318, and the corresponding display unit is a first LED bead 31811. The first LED beads 31811 are arranged in two rows along the second direction. The upper row includes 22 first LED beads 31811, and the lower row includes 24 first LED beads 31811. In this embodiment, two adjacent rows of first LED beads 31811 along the second direction belong to a group of rhythmic units. As shown in Figure 30, the first LED beads 31811 are divided into 6 rhythmic units L1, L2, L3, L4, L5, L6 on the left and 6 rhythmic units R1, R2, R3, R4, R5, R6 on the right. Each rhythmic unit occupies an equal width (distance along the second direction). Furthermore, each of the 10 rhythmic units from L5 to R5 in the figure includes 4 first LED beads 31811, while L6 and R6 each include 3 first LED beads 31811.

[0718] In another specific alternative embodiment, the first LED beads 31811 of the display element are divided into multiple groups of rhythmic units according to other rules. For example, they are grouped according to the number of first LED beads 31811; referring again to Figure 30, from the middle to both sides of the display element, four first LED beads 31811 form a group of rhythmic units, and fewer than four first LED beads 31811 are also counted as a group of rhythmic units. In this case, the display element in the figure is divided into 12 groups according to the number of first LED beads 31811, including 6 rhythmic units located in the left half of the display element: L1, L2, L3, L4, L5, L6 and 6 rhythmic units located in the right half: R1, R2, R3, R4, R5, R6.

[0719] The purpose of grouping the first LED beads 31811 of the display unit is to simplify the control of the display unit by the headlight controller. For the grouped display unit, the headlight controller only needs to send one control signal to one group of rhythm units. That is, the headlight controller only needs to send one control signal to complete the control of the four first LED beads 31811. Compared with the headlight controller controlling each first LED bead 31811 individually, the load on the headlight controller is greatly reduced.

[0720] In one specific alternative embodiment, when the display is controlled by the headlight controller, it operates at least partially at one of the following lighting effects:

[0721] (1) Unidirectional flowing light effect: at least some of the rhythm units are lit or extinguished sequentially along the second direction.

[0722] (2) Diffuse flowing light effect: The rhythmic unit of the display component lights up or turns off sequentially from the middle to both sides.

[0723] (3) Converging flowing light effect: The rhythmic units of the display component light up or turn off sequentially from both sides toward the middle.

[0724] Specifically, unidirectional flowing light effects include partial unidirectional flowing light and overall unidirectional flowing light.

[0725] The partial unidirectional lighting effect refers to the sequential lighting or extinguishing of certain rhythmic units of the display element along a second direction. Referring to Figure 31 as an example: In some specific embodiments, the partial unidirectional lighting effect involves the six rhythmic units in the left half of the display element lighting or extinguishing sequentially from left to right or from right to left. Figure 31 shows the states of the six rhythmic units in the left half of the display element at six different times. The first LED 31811, which has outwardly radiating ring segments, is indicated as being lit; the others are in an off state. The black arrows in the figure indicate the order of these states. That is, in this embodiment, the six rhythmic units: L1, L2, L3, L4, L5, and L6 are lit sequentially, and when one is lit, the other rhythmic units are off.

[0726] Accordingly, in another optional embodiment, the six rhythmic units on the left half of the above-mentioned display can also be lit sequentially from right to left, that is, each rhythmic unit changes state in the opposite direction to the direction shown by the black arrow in Figure 31.

[0727] Furthermore, in another optional embodiment, the six rhythmic units on the right half of the display can also display a local unidirectional flow state in the manner described above, where they are lit sequentially from right to left or from left to right.

[0728] In another optional embodiment, all the rhythmic units of the display are sequentially lit or turned off along the second direction. That is, during a certain period of time, the 12 rhythmic units of the display are lit sequentially from left to right, that is, the 12 rhythmic units: L6, L5, L4, L3, L2, L1, R1, R2, R3, R4, R5, R6 are lit in sequence, and when one rhythmic unit is lit, the other rhythmic units are in an off state.

[0729] In another optional embodiment, during a certain period of time, the 12 rhythm units of the display are lit sequentially from right to left, that is, the 12 rhythm units are lit in the order of R6, R5, R4, R3, R2, R1, L1, L2, L3, L4, L5, L6, and when one rhythm unit is lit, the other rhythm units are in an off state.

[0730] As described above, the rhythmic unit of the display is turned on or off according to a predetermined pattern. Here, the time period from the start to the end of a lighting effect is defined as a cycle.

[0731] In some optional embodiments, the cycles of the two lighting effects executed by the display do not overlap, that is, the display starts executing the other lighting effect only after completing one lighting effect.

[0732] In another optional embodiment, the cycles of at least two lighting effects executed by the display device at least partially overlap, meaning that the other lighting effect begins to execute before the display device completes one lighting effect. Referring to Figure 32, the figure shows another embodiment in which the left half of the display device executes two unidirectional flowing light effects simultaneously. Specifically: when the first unidirectional flowing light effect executes until L4 is lit and L3 is off, L1 is lit; subsequently, when L5 is lit and L4 is off, L2 is lit and L1 is off; when L6 is lit and L5 is off, L3 is lit and L2 is off. This means that the two unidirectional flowing light effects executed by the left half partially overlap.

[0733] In another optional embodiment, only the rhythmic units near the edge of the display element perform a unidirectional sequential lighting effect. This portion is defined as the turn signal display area, and when the turn signal display area performs the unidirectional sequential lighting effect, it presents the sequential turn signal effect of the vehicle. Specifically, the sequential turn signal effect is that the rhythmic units near the center of the display element in the turn signal display area are lit first, and then adjacent rhythmic units are lit in sequence until the rhythmic unit closest to the edge of the display element is lit, and the above sequential turn signal effect is repeated, which is the lighting effect when the vehicle turns.

[0734] The diffused flowing light effect is characterized by at least some of the rhythmic units of the display components lighting up or turning off sequentially from the center to both sides. The convergent flowing light effect is characterized by at least some of the rhythmic units of the display components lighting up or turning off sequentially from both sides to the center.

[0735] That is, when performing a diffused or converged flowing light effect, the rhythm units of the left and right halves of the display simultaneously execute a unidirectional flowing light state in opposite directions.

[0736] In some optional embodiments, all the rhythmic units of the display participate in either a diffused or converged flowing light effect. Specifically, in one embodiment, when the display performs a diffused flowing light effect, the rhythmic units on the left half of the display turn on or off sequentially from right to left, and the rhythmic units on the right half of the display turn on or off sequentially from left to right. In another embodiment, when the display performs a converged flowing light effect, the rhythmic units on the left half of the display turn on or off sequentially from left to right, and the rhythmic units on the right half of the display turn on or off sequentially from right to left.

[0737] It should be noted that the above-mentioned diffused flowing light effect and converged flowing light effect can be regarded as the display device simultaneously executing two unidirectional flowing light effects, that is, the cycles of the two unidirectional flowing light effects executed by the display device as described above completely overlap.

[0738] In the above embodiments, all rhythm units of the display device participate in the lighting effect. In another optional embodiment, some rhythm units of the display device participate in at least one of the above lighting effects. That is, the execution of one of the above lighting effects by some rhythm units of the display device should not be construed as exceeding the protection scope of the above embodiments.

[0739] In some optional embodiments, when the display device performs a unidirectional flowing light effect, a diffused flowing light effect, or a converged flowing light effect, at least two adjacent rhythmic units are lit or turned off at intervals of a first duration, the first duration being 50ms to 300ms. In one specific embodiment, when the left half of the display device performs a unidirectional flowing light effect, the initial state is defined as all rhythmic units being off. The image in the initial state is defined as the first frame, L1 being lit as the second frame, L2 being lit and L1 being off as the third frame, ..., L6 being lit and L5 being off as the seventh frame. There are six first durations between the first and seventh frames. As mentioned above, the first duration is 50ms to 300ms, which means that one cycle of the left half performing the unidirectional flowing light effect is 300ms to 1800ms. Specifically, the cycle of the left half performing the unidirectional flowing light effect is set to 1000ms, meaning the first duration is approximately 166.7ms.

[0740] In one of the optional embodiments, two adjacent rhythmic units constitute a rhythmic group; when the display performs a unidirectional flowing light effect, a diffused flowing light effect, or a converged flowing light effect, the two rhythmic units in the rhythmic group are lit or turned off at a second interval of a second duration. The second duration is different for different rhythmic groups, ranging from 50ms to 300ms.

[0741] For example: the three consecutive rhythmic units in the display constitute two rhythmic groups: a first rhythmic group and a second rhythmic group; the first rhythmic group consists of a first rhythmic unit and a second rhythmic unit, and the second rhythmic group consists of a second rhythmic unit and a third rhythmic unit. The time period from when the first rhythmic unit is lit to when the third rhythmic unit is lit includes two second durations, and the two second durations are not equal; in some embodiments, the second durations of multiple adjacent rhythmic groups gradually increase or decrease, and the actual lighting effect is the decrease or increase of the rhythmic frequency of the rhythmic units.

[0742] In one of the optional embodiments, one of the rhythmic units in one of the rhythmic groups turns off after a third duration following being illuminated, the third duration being greater than or equal to the second duration of one of the rhythmic groups. That is, one rhythmic unit turns off only after two adjacent rhythmic units are both illuminated, resulting in a lighting effect that appears to transmit light more effectively.

[0743] In some optional embodiments, the unidirectional flowing light effect, the diffused flowing light effect, or the converging flowing light effect each have a standard unidirectional duration, a standard diffused duration, and a standard converging duration for running one cycle at a standard speed.

[0744] The one-way standard duration is 0.6s to 1.8s;

[0745] The diffusion standard duration is 0.8s to 2.0s;

[0746] The standard duration for gathering is 0.5s to 2.0s.

[0747] In some optional embodiments, the unidirectional flowing light effect, the diffused flowing light effect, or the converging flowing light effect further includes a unidirectional double speed duration, a diffused double speed duration, and a converging double speed duration that move at a specific multiple of the standard speed for one cycle.

[0748] The unidirectional speed-up duration = unidirectional standard duration / specific multiple;

[0749] The diffusion rate multiplication time = standard diffusion time / specific multiplication factor;

[0750] The acceleration time = standard acceleration time / specific multiple;

[0751] The specific multiple is a positive real number greater than 0.5 and less than or equal to 2.

[0752] That is:

[0753] The duration of the unidirectional speed-doubling is 0.3s to 3.6s;

[0754] The diffusion rate doubling time is 0.4 s to 4.0 s;

[0755] The aggregation speed-up duration is 0.25s to 4.0s.

[0756] In one of the optional embodiments, when the multi-functional work vehicle is powered on and the headlight controller is powered on, the display device performs a power-on lighting effect, which includes at least one diffused flowing light effect.

[0757] Furthermore, in some optional embodiments, at at least one moment when the display device performs the power-on lighting effect, the display device is in a state where two diffused flowing lighting effects are being performed simultaneously. That is, the power-on lighting effect of the display device includes two diffused flowing lighting effects performed sequentially, and the second flowing lighting effect begins to perform before the first lighting effect has ended.

[0758] Furthermore, in some optional embodiments, when the display starts to perform the power-on lighting effect, it first performs a diffused flowing light effect: the rhythm unit located in the center of the display lights up and then lights up the rhythm units on both sides in sequence, and the rhythm unit turns off when the adjacent rhythm unit lights up;

[0759] During the fourth duration of the power-on lighting effect, the display device executes the diffused flowing light effect again: the rhythm unit located in the middle position lights up and the rhythm units on both sides light up in sequence, and the rhythm unit turns off when the adjacent rhythm unit lights up;

[0760] The fourth duration is longer than the second duration, and the fourth duration is shorter than one cycle duration of the diffused flowing light effect.

[0761] In some optional embodiments, when the display is simultaneously executing two diffusion flow units, the two illuminated rhythmic units are spaced at least one rhythmic unit apart in position. This is to avoid treating two adjacent rhythmic units as a single rhythmic unit while they are operating synchronously.

[0762] In some optional embodiments, the display includes N rhythm units:

[0763] When N is an even number, the middle rhythm unit consists of two rhythm units; that is, the rightmost rhythm unit on the left half of the display and the leftmost rhythm unit on the right half of the display are not the same rhythm unit.

[0764] When N is an odd number, the middle rhythm unit is a single rhythm unit; that is, the rightmost rhythm unit on the left half of the display and the leftmost rhythm unit on the right half of the display are the same rhythm unit.

[0765] In some optional embodiments, when the display begins to execute a unidirectional flowing light effect, the rhythmic units located at one edge of the display are illuminated, and the rhythmic units are sequentially illuminated along a second direction until the rhythmic units at the other edge of the display are illuminated. That is, all rhythmic units of the display participate in the unidirectional flowing light effect. Further, in a more specific embodiment, at least one illuminated rhythmic unit is extinguished when its adjacent rhythmic unit is illuminated. That is, during the unidirectional flowing light effect, only one rhythmic unit is illuminated at any given time.

[0766] In some optional embodiments, after the display element performs a unidirectional flowing light effect and the rhythmic unit on the other edge is lit, the rhythmic units are sequentially lit in the opposite direction of the second direction until all the rhythmic units of the display element are simultaneously lit. That is, in some embodiments, after the display element completes one unidirectional flowing light effect, all the rhythmic units are gradually lit.

[0767] Furthermore, in some embodiments, the entire rhythmic unit of the display device, after being simultaneously lit, alternates between turning off and on at fifth time intervals. That is, the entire display device is in a flashing state.

[0768] In one of the optional embodiments, when the display starts to execute the converging flowing light effect, the rhythm units located on both sides of the display are lit up, and the adjacent rhythm units of the lit rhythm units are lit up in sequence until the middle rhythm unit is lit up.

[0769] In one of the optional embodiments, the converging flowing light effect is achieved by sequentially lighting up the rhythmic units of the display from both sides towards the center, and during the process of the converging flowing light effect, the already lit rhythmic units do not turn off until all the rhythmic units are lit up at the same time.

[0770] In some optional embodiments, the converging flowing light effect is achieved by the rhythmic units of the display element lighting up sequentially from both sides towards the center. Specifically, the display element includes N rhythmic units, and the converging flowing light effect includes n sequentially executed converging phases.

[0771] Here The sign for rounding up means that when N is odd, n = (N+1) / 2, and when N is even, n = N / 2.

[0772] At the start of the first convergence phase, the rhythmic units located at both edges of the display are illuminated; at the end of the first convergence phase, the rhythmic unit located in the center is illuminated; during the process of the first convergence phase, the rhythmic units are illuminated sequentially along the direction closest to the center until the end of the first convergence phase is reached; during the process of the first convergence phase, when a rhythmic unit is illuminated, the adjacent rhythmic unit that was illuminated in the first convergence phase is extinguished.

[0773] The second convergence phase begins at the end of the first convergence phase, at which time the rhythmic units located at both edges of the display are illuminated; at the end of the second convergence phase, the rhythmic units adjacent to the rhythmic units illuminated at the end of the first convergence phase remain illuminated; during the process of the second convergence phase, when the rhythmic units are illuminated, the rhythmic units adjacent to them that were illuminated in the second convergence phase are extinguished.

[0774] The (n-1)th gathering phase begins at the end of the (n-2)th gathering phase, at which time the rhythmic units located at both edges of the display element are illuminated; at the end of the (n-1)th gathering phase, only the rhythmic units at both edges of the display element are in an off state; during the process of the (n-1)th gathering phase, when the rhythmic unit is illuminated, the adjacent rhythmic unit illuminated in the (n-1)th gathering phase is extinguished;

[0775] The nth gathering stage involves illuminating the rhythmic units on both sides of the display element. At this point, all rhythmic units of the display element are illuminated, completing the gathering flowing light effect of this embodiment.

[0776] In one of the optional embodiments, the display device performs a diffused flowing light effect after completing the converged flowing light effect; all the rhythm units of the display device are lit up when the converged flowing light effect is completed; the diffused flowing light effect performed by the display device after completing the converged flowing light effect is: the rhythm units of the display device turn off sequentially from the middle to both sides until all the rhythm units of the display device are turned off.

[0777] In some optional embodiments, the dimensions of each rhythmic unit along the second direction are equal, the power ratio of two adjacent rhythmic units is greater than or equal to 50%, and the power of a rhythmic unit is equal to the sum of the power of its display units. This avoids excessive brightness differences between adjacent rhythmic units due to large power disparities, which could affect the visual continuity of the light. In some more specific embodiments, referring to Figure 30, the rhythmic units at the two edges of the display include three display units, while the other rhythmic units each include four display units. In this embodiment, the power ratio of two adjacent rhythmic units is not less than 75%, and their brightness differences are not significant and will not affect the visual continuity when illuminated.

[0778] In some optional embodiments, the headlight controller controls the brightness of the display to decrease when the left headlight 317 and / or the right headlight 316 is illuminated. When the left headlight 317 and right headlight 316 are off, the display can function as a daytime running light, i.e., to improve vehicle visibility, especially in well-lit environments. The illuminated display makes the vehicle easily visible to people around it, facilitating identification of the multi-functional work vehicle and reducing the probability of risk due to failure to recognize the vehicle. Therefore, when the left headlight 317 and right headlight 316 are illuminated, the display's function as a daytime running light 318 to improve visibility is unnecessary; hence, the headlight controller controls the power of the display to decrease, i.e., to reduce the brightness of the display. In some optional embodiments, the headlight controller controls the brightness of the display to decrease by 50% when the left headlight 317 and / or right headlight 316 are illuminated; in other embodiments, the brightness of the display may be reduced by 40% or 30%.

[0779] In some embodiments of this specification, daytime running lights are arranged in front of the vehicle and illuminated when the vehicle is in operation to improve the vehicle's visibility, making it easier for people around to spot the vehicle. In particular, during the daytime or when lighting conditions are good, the vehicle's working parts are not in operation and do not produce noise that is easily perceived by people. The vehicle's daytime running lights are illuminated or flashed to improve the vehicle's visibility.

[0780] In one of the optional embodiments, referring to Figures 1 and 24, the multi-functional work vehicle further includes a taillight 7 disposed on the rear side of the frame 1 and emitting red light towards the rear of the vehicle. The taillight 7 is illuminated to facilitate identification by personnel or vehicles located behind the vehicle.

[0781] In one of the optional embodiments, referring to Figures 25 and 26, the taillight 7 includes a rear light strip 72 that is powered to emit light and a rear light cover that covers the rear light strip 72. The rear light strip 72 is provided with a tail light bead 721, and the light emitted by the light bead passes through the rear light cover and is emitted rearward.

[0782] As described above, the taillight 7 emits red light. In one optional embodiment, the rear light strip 72 emits red light when energized. In this embodiment, the rear light cover 73 can be configured to be colorless or red to increase the outward transmission rate of red light. In another optional embodiment, the rear light cover 73 is made of red semi-transparent material. In this embodiment, the taillight bulb 721 can be configured to emit white or red light so that the light emitted by the taillight 7 is red.

[0783] In some optional embodiments, the rear lamp cover 73 does not obstruct the light direction of the taillight 7. That is, there are no components such as a baffle behind the rear lamp cover 73 that would block the light from the taillight 7, thereby maximizing the effective amount of light emitted rearward by the taillight 7.

[0784] In some optional embodiments, a portion of the rear light strip 72 is tilted towards the rear side of the vehicle. That is, a portion of the taillight 7 emits light diagonally rearward. Therefore, even vehicles located diagonally behind the vehicle can clearly see the taillight 7 of this embodiment, thus quickly identifying the presence of the multi-functional work vehicle.

[0785] In some optional embodiments, the multi-functional work vehicle further includes a rear light controller and a taillight 7 disposed on the rear side of the frame 1 and facing the rear of the vehicle. The taillight 7 includes an array of rear light units (i.e., tail light beads 721), and several adjacent rear light units are configured as a group of rhythmic units. When the rear light controller controls the taillight 7 to work, the working state of the rear light units in the group of rhythmic units changes synchronously.

[0786] In one alternative embodiment, each group of rhythmic units occupies approximately equal space in the taillight 7, so that when the lighting effect switches, the visual effect is closer to the movement of a single rhythmic unit as the two rhythmic units alternately light up.

[0787] In one specific alternative embodiment, referring to Figure 25, the taillight 7 includes three rear light strips 72. The rear light units and the first LED bead 31811 mentioned above are both LED beads. The rear light strip 72 located in the middle of the figure is equipped with 20 rear light units, and the rear light strips 72 on both sides are equipped with 8 rear light units, and all the rear light units are located at the same height.

[0788] Referring to Figure 25, a total of 36 rear light units are configured in this embodiment, with 4 rear light units configured as one rhythm unit, for a total of 9 rhythm units.

[0789] The purpose of grouping the taillight units of taillight 7 is to simplify the control of taillight 7 by the taillight controller. For the grouped taillight 7, the taillight controller only needs to send one control signal to one group of rhythm units. That is, the rhythm unit only needs to send one control signal to complete the control of four taillight units. Compared with the taillight controller controlling each taillight unit individually, this significantly reduces the load on the taillight controller.

[0790] In one specific alternative embodiment, the taillight 7, when controlled by the rear light controller, operates at least partially at one of the following lighting effects:

[0791] (1) One-way flowing light effect: at least some of the rhythm units of the taillights 7 are lit or turned off sequentially along the second direction.

[0792] (2) Diffuse flowing light effect: The rhythmic unit of the taillight 7 lights up or turns off sequentially from the middle to both sides.

[0793] (3) Converging flowing light effect: The rhythmic unit of the taillight 7 lights up or turns off sequentially from both sides toward the middle.

[0794] Specifically, unidirectional flowing light effects include partial unidirectional flowing light and overall unidirectional flowing light.

[0795] The partial unidirectional flowing light effect involves some rhythmic units of the taillight 7 sequentially lighting up or turning off in the second direction. Especially when displaying turn signal effects, some rhythmic units located on the left or right side of the taillight 7 execute the unidirectional flowing light effect.

[0796] In another optional embodiment, all the rhythmic units of the taillight 7 are sequentially lit or turned off along the second direction. That is, during a certain period of time, the nine rhythmic units of the taillight 7 are lit sequentially from left to right, and when one rhythmic unit is lit, the other rhythmic units are in an off state.

[0797] In another optional embodiment, during certain periods of time, the nine rhythmic units of the taillight 7 are lit sequentially from right to left, and when one rhythmic unit is lit, the other rhythmic units are off.

[0798] As described above, the rhythm unit of the taillight 7 is turned on or off according to a predetermined pattern. Here, a period of time from the start to the end of a lighting effect is defined as a cycle.

[0799] In some optional embodiments, the cycles of the two lighting effects performed by the taillight 7 do not overlap, that is, the taillight 7 starts performing the other lighting effect only after completing one lighting effect.

[0800] In another optional embodiment, the cycles of at least two lighting effects performed by the taillight 7 overlap at least partially, that is, when the taillight 7 has not completed one lighting effect, the other lighting effect has already begun to be performed.

[0801] In another optional embodiment, only the rhythmic units near the edge of the taillight 7 perform a one-way sequential lighting effect. This portion is defined as the turn signal display area, and when the turn signal display area performs a one-way sequential lighting effect, it presents the vehicle's sequential turn signal effect. Specifically, the sequential turn signal effect is that the rhythmic unit near the center of the taillight 7 in the turn signal display area is lit first, and then adjacent rhythmic units are lit sequentially until the rhythmic unit closest to the edge of the taillight 7 is lit, and the above sequential turn signal effect is repeated, which is the lighting effect when the vehicle turns.

[0802] The diffused flowing light effect is that at least some of the rhythmic units of the taillights 7 light up or turn off sequentially from the center to both sides. The converging flowing light effect is that at least some of the rhythmic units of the taillights 7 light up or turn off sequentially from both sides to the center.

[0803] That is, when performing a diffused or converged flowing light effect, the rhythm units of the left and right halves of the taillight 7 simultaneously execute a unidirectional flowing state in opposite directions.

[0804] In some optional embodiments, all the rhythmic units of the taillight 7 participate in either a diffused or converged flowing light effect. Specifically, in one embodiment, when the taillight 7 performs a diffused flowing light effect, the rhythmic units of the left half of the taillight 7 light up or turn off sequentially from right to left, and the rhythmic units of the right half of the taillight 7 light up or turn off sequentially from left to right. In another embodiment, when the taillight 7 performs a converged flowing light effect, the rhythmic units of the left half of the taillight 7 light up or turn off sequentially from left to right, and the rhythmic units of the right half of the taillight 7 light up or turn off sequentially from right to left.

[0805] It should be noted that the above-mentioned diffused flowing light effect and converged flowing light effect can be regarded as the taillight 7 performing two unidirectional flowing light effects at the same time, that is, the cycles of the taillight 7 performing two unidirectional flowing light effects as described above completely overlap.

[0806] In the above embodiments, all rhythmic units of the taillight 7 participate in the lighting effect. In another optional embodiment, some rhythmic units of the taillight 7 participate in at least one of the above lighting effects. That is, the fact that some rhythmic units of the taillight 7 perform one of the above lighting effects should not be construed as exceeding the protection scope of the above embodiments.

[0807] In some optional embodiments, when the taillight 7 performs a unidirectional flowing light effect, a diffused flowing light effect, or a converged flowing light effect, at least two adjacent rhythmic units are lit or turned off at intervals of a first duration, the first duration being 50ms to 300ms.

[0808] In one of the optional embodiments, two adjacent rhythmic units constitute a rhythmic group; when the taillight 7 performs a unidirectional flowing light effect, a diffused flowing light effect, or a converged flowing light effect, the two rhythmic units in the rhythmic group are lit or turned off at a second interval of a second duration. The second duration is different for different rhythmic groups, ranging from 50ms to 300ms.

[0809] For example: the three consecutive rhythmic units in the taillight 7 constitute two rhythmic groups: a first rhythmic group and a second rhythmic group; the first rhythmic group consists of a first rhythmic unit and a second rhythmic unit, and the second rhythmic group consists of a second rhythmic unit and a third rhythmic unit. The time period from when the first rhythmic unit is lit to when the third rhythmic unit is lit includes two second durations, and the two second durations are not equal; in some embodiments, the second durations of multiple adjacent rhythmic groups gradually increase or decrease, and the actual lighting effect is that the rhythmic frequency of the rhythmic units decreases or increases.

[0810] In one of the optional embodiments, one of the rhythmic units in one of the rhythmic groups turns off after a third duration following being illuminated, the third duration being greater than or equal to the second duration of one of the rhythmic groups. That is, one rhythmic unit turns off only after two adjacent rhythmic units are both illuminated, resulting in a lighting effect that appears to transmit light more effectively.

[0811] In some optional embodiments, the unidirectional flowing light effect, the diffused flowing light effect, or the converging flowing light effect each have a standard unidirectional duration, a standard diffused duration, and a standard converging duration for running one cycle at a standard speed.

[0812] The one-way standard duration is 0.6s to 1.8s;

[0813] The diffusion standard duration is 0.8s to 2.0s;

[0814] The standard duration for gathering is 0.5s to 2.0s.

[0815] In some optional embodiments, the unidirectional flowing light effect, the diffused flowing light effect, or the converging flowing light effect further includes a unidirectional double speed duration, a diffused double speed duration, and a converging double speed duration that move at a specific multiple of the standard speed for one cycle.

[0816] The unidirectional speed-up duration = unidirectional standard duration / specific multiple;

[0817] The diffusion rate multiplication time = standard diffusion time / specific multiplication factor;

[0818] The acceleration time = standard acceleration time / specific multiple;

[0819] The specific multiple is a positive real number greater than 0.5 and less than or equal to 2.

[0820] That is:

[0821] The duration of the unidirectional speed-doubling is 0.3s to 3.6s;

[0822] The diffusion rate doubling time is 0.4 s to 4.0 s;

[0823] The aggregation speed-up duration is 0.25s to 4.0s.

[0824] In one of the optional embodiments, when the multi-functional work vehicle is turned on and powers on the rear light controller, the taillight 7 performs a power-on lighting effect, which includes at least one diffused flowing light effect.

[0825] Furthermore, in some optional embodiments, at least at one moment when the taillight 7 performs the power-on lighting effect, the taillight 7 is in a state where two diffused flowing lighting effects are being performed simultaneously. That is, the power-on lighting effect of the taillight 7 includes two diffused flowing lighting effects performed sequentially, and the second flowing lighting effect begins to perform before the first lighting effect has ended.

[0826] Furthermore, in some optional embodiments, when the taillight 7 starts to perform the power-on lighting effect, it first performs a diffused flowing light effect: the rhythm unit located in the middle of the taillight 7 lights up and then lights up the rhythm units on both sides in sequence, and the rhythm unit turns off when the adjacent rhythm unit lights up;

[0827] During the fourth duration of the power-on lighting effect of the taillight 7, the taillight 7 again performs a diffused flowing light effect: the rhythm unit located in the middle position lights up and the rhythm units on both sides light up in sequence, and the rhythm unit turns off when the adjacent rhythm unit lights up;

[0828] The fourth duration is longer than the second duration, and the fourth duration is shorter than one cycle duration of the diffused flowing light effect.

[0829] In some optional embodiments, when the taillight 7 is simultaneously executing two diffusion flow units, the two illuminated rhythmic units are spaced at least one rhythmic unit apart in position. This is to avoid treating two adjacent rhythmic units as a single rhythmic unit due to synchronous operation.

[0830] In some optional embodiments, the display includes N rhythm units:

[0831] When N is an even number, the middle rhythm unit consists of two rhythm units; that is, the rightmost rhythm unit on the left half of the display and the leftmost rhythm unit on the right half of the display are not the same rhythm unit.

[0832] When N is an odd number, the middle rhythm unit is a single rhythm unit; that is, the rightmost rhythm unit on the left half of the display and the leftmost rhythm unit on the right half of the display are the same rhythm unit.

[0833] In some optional embodiments, when the taillight 7 begins to execute the one-way flowing light effect, the rhythmic unit located at one edge of the taillight 7 is illuminated, and the rhythmic units are illuminated sequentially along the second direction until the rhythmic unit at the other edge of the taillight 7 is illuminated. That is, all rhythmic units of the taillight 7 participate in the one-way flowing light effect. Further, in a more specific embodiment, at least one illuminated rhythmic unit is extinguished when its adjacent rhythmic unit is illuminated. That is, during the one-way flowing light effect, only one rhythmic unit is illuminated at any given time.

[0834] In some optional embodiments, after the taillight 7 performs a one-way flowing light effect and the rhythmic unit on the other edge is illuminated, the rhythmic units are sequentially illuminated in the opposite direction of the second direction until all the rhythmic units of the taillight 7 are simultaneously illuminated. That is, in some embodiments, after the taillight 7 completes one one-way flowing light effect, all the rhythmic units are gradually illuminated.

[0835] Furthermore, in some embodiments, the entire rhythmic unit of the taillight 7, after being simultaneously illuminated, alternates between extinguishing and illuminating at intervals of five time periods. That is, the entire display element is in a flashing state.

[0836] In one of the optional embodiments, when the taillight 7 begins to perform the converging flowing light effect, the rhythmic units located on both sides of the taillight 7 are lit up, and the adjacent rhythmic units of the lit rhythmic units are lit up in sequence until the middle rhythmic unit is lit up.

[0837] In one of the optional embodiments, the converging flowing light effect is that the rhythmic units of the taillight 7 are lit sequentially from both sides to the middle, and during the process of the converging flowing light effect, the already lit rhythmic units do not turn off until all the rhythmic units are lit at the same time.

[0838] In one of the optional embodiments, the converging flowing light effect is achieved by the rhythmic units of the taillights 7 lighting up sequentially from both sides towards the center. Specifically, the taillights 7 include N rhythmic units, and the converging flowing light effect includes n sequentially executed converging phases.

[0839] Here The sign for rounding up means that when N is odd, n = (N+1) / 2, and when N is even, n = N / 2.

[0840] At the start of the first convergence phase, the rhythmic units located on both sides of the taillight 7 are illuminated; at the end of the first convergence phase, the rhythmic unit located in the center is illuminated; during the process of the first convergence phase, the rhythmic units are illuminated sequentially along the direction closest to the center until the end of the first convergence phase is reached; during the process of the first convergence phase, when a rhythmic unit is illuminated, the rhythmic unit adjacent to it that was illuminated in the first convergence phase is extinguished.

[0841] The second convergence phase begins at the end of the first convergence phase, at which time the rhythmic units located on both sides of the taillight 7 are illuminated; at the end of the second convergence phase, the rhythmic units adjacent to the rhythmic units illuminated at the end of the first convergence phase remain illuminated; during the process of the second convergence phase, when the rhythmic units are illuminated, the rhythmic units adjacent to them that were illuminated in the second convergence phase are extinguished.

[0842] The (n-1)th gathering phase begins at the end of the (n-2)th gathering phase, at which time the rhythmic units located on both sides of the taillight 7 are illuminated; at the end of the (n-1)th gathering phase, only the rhythmic units on both sides of the taillight 7 are in an off state; during the process of the (n-1)th gathering phase, when the rhythmic unit is illuminated, the adjacent rhythmic unit illuminated in the (n-1)th gathering phase is extinguished.

[0843] The nth gathering stage involves illuminating the rhythmic units on both sides of the taillight 7. At this point, all rhythmic units of the taillight 7 are illuminated, completing the gathering flowing light effect of this embodiment.

[0844] In one of the optional embodiments, the taillight 7 performs a diffused flowing light effect after completing the converging flowing light effect; all the rhythmic units of the taillight 7 are lit when the converging flowing light effect is completed; the diffused flowing light effect performed by the taillight 7 after completing the converging flowing light effect is: the rhythmic units of the taillight 7 turn off sequentially from the middle to both sides until all the rhythmic units of the taillight 7 are turned off.

[0845] In some optional embodiments, each of the rhythmic units has the same size along the second direction, the power ratio of two adjacent rhythmic units is greater than or equal to 50%, and the power of a rhythmic unit is equal to the sum of the power of the display units of that rhythmic unit. This avoids excessive brightness differences between adjacent rhythmic units due to excessive power differences, which could affect the visual continuity of the light.

[0846] Referring to Figure 67, a connection diagram of the vehicle lighting system is shown. The vehicle's power system is connected to the vehicle controller, which in turn connects to the headlight assembly and taillight assembly. Specifically, the battery system includes a battery and a BMS (Battery Management System). The headlight assembly includes the aforementioned headlight controller, left headlight, daytime running light, and right headlight. The taillight assembly includes the aforementioned taillight controller and taillight. Electrical energy is output from the battery and supplied to the vehicle controller via the BMS. The vehicle controller then transmits the electrical energy to the headlight controller and taillight controller. The headlight controller distributes the electrical energy to the left headlight, daytime running light, and right headlight, while the taillight controller distributes the electrical energy to the taillight. This completes the power supply to the left headlight, daytime running light, right headlight, and taillight.

[0847] In some optional embodiments, the lighting system is part of the vehicle's low-voltage system, so the left headlight, daytime running light, right headlight, and taillight can be directly powered by the controller.

[0848] In some optional embodiments, the vehicle controller sends lighting control signals to the front light controller and the rear light controller to control the left headlight, daytime running lights, right headlight, and taillight.

[0849] This embodiment discloses a multi-functional work vehicle. Referring to Figure 1, it includes a frame 1 and an outdoor work component. The frame 1 extends along a first direction, which is also the front-rear direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work.

[0850] The multi-functional work vehicle in this embodiment also includes a headlight assembly. Further, the headlight assembly includes a light-emitting part and a lamp cover, wherein the light-emitting part is used to emit light towards the front of the vehicle, and the lamp cover is used to house the light-emitting part. As described above, the light-emitting part includes the aforementioned left headlight 317, right headlight 316, and daytime running light 318. Further, the lamp cover includes at least two light-transmitting holes 38 located at the front and at least one baffle 37 for separating each light-transmitting hole. The light from the light-emitting part is emitted towards the front of the vehicle through the light-transmitting holes 38.

[0851] In one optional embodiment, referring to Figure 33, the lamp cover includes an inner lamp cover and an outer lamp cover 2. The inner lamp cover is housed within the outer lamp cover. The light-emitting part is disposed inside the inner lamp cover and emits light forward. The outer lamp cover 2 has an external light-transmitting hole facing forward of the vehicle, and the inner lamp cover has an internal light-transmitting hole facing forward of the vehicle. The outer wall of the external light-transmitting hole is slightly larger than the internal light-transmitting hole, meaning that the sidewall of the external light-transmitting hole does not obstruct the light transmitted through the internal light-transmitting hole, thus preventing the outer lamp cover 2 from affecting the light-emitting part's forward illumination effect.

[0852] In one of the optional embodiments, referring to Figures 33 and 34, the baffle 37 is disposed on the front wall of the inner lampshade. Specifically, the figures show that the inner lampshade is provided with two baffles 37: a first baffle 371 and a second baffle 372, thereby dividing the inner light-transmitting hole into a first light-transmitting hole 381, a second light-transmitting hole 382, ​​and a third light-transmitting hole 383.

[0853] In some optional embodiments, as previously described, the inner lamp cover includes a front lamp holder 31 and a front lamp cover 32, which together form a space for accommodating the light-emitting portion.

[0854] In one of the optional embodiments, referring to Figure 35, the baffle 37 is disposed on the front wall of the outer lamp cover 2. Specifically, the figure shows that the outer lamp cover 2 is provided with two baffles 37: a third baffle 373 and a fourth baffle 374, thereby dividing the inner light-transmitting hole into a fourth light-transmitting hole 384, a fifth light-transmitting hole 385, and a sixth light-transmitting hole 386.

[0855] In some optional embodiments, referring to Figure 36, a light-emitting portion located inside the inner lamp housing is shown, which is energized and emits light forward toward the vehicle. As previously described, the light-emitting portion includes at least a left headlight 317, a right headlight 316, and a daytime running light 318.

[0856] Furthermore, referring to Figures 33, 34, and 36, a portion of the inner lampshade is positioned directly in front of the light-emitting part. To ensure that the inner lampshade does not obstruct the light emitted by the light-emitting part, the portion of the inner lampshade in front of the light-emitting part should be made of a transparent material. Even further, in some embodiments, the entire inner lampshade is made of a transparent material.

[0857] The sum of the projected areas of each of the light-transmitting holes 34 along the first direction is S1, and the projected area of ​​the at least one baffle 37 along the first direction is S2. The ratio of S2 to S1 is less than 0.1. Because the area of ​​the baffle 37 is small and much smaller than the area of ​​the light-transmitting holes 38, the light-transmitting holes 38 appear to be almost completely connected.

[0858] Referring to Figure 34, S1 is the sum of the projected areas of the first light-transmitting hole 381, the second light-transmitting hole 382, ​​and the third light-transmitting hole 383 in the first direction, and S2 is the sum of the projected areas of the first baffle 371 and the second baffle 372 in the first direction.

[0859] Referring to Figure 35, S1 is the sum of the projected areas of the fourth light-transmitting hole 384, the fifth light-transmitting hole 385, and the sixth light-transmitting hole 386 in the first direction, and S2 is the sum of the projected areas of the third barrier strip 373 and the fourth barrier strip 374 in the first direction.

[0860] In some optional embodiments, the sum of the areas of at least two of the light-transmitting holes 38 projected along the first direction is 100 cm². 2 ~600cm 2 Furthermore, in one more specific embodiment, the sum of the areas projected along the first direction by at least two of the light-transmitting holes 38 is 350 cm². 2 ~450cm 2 As mentioned earlier, since the baffle 37 in front of the lamp cover is small, it does not substantially obstruct the light emitted by the light-emitting part, and the light-transmitting hole 38 can reach the aforementioned area, providing the space conditions for the headlight to emit sufficiently intense light to the outside. For relatively stable lighting needs, it can reduce the light intensity required per unit space inside the headlight. Since the light emitted by the lamp is proportional to the heat generated, it can also reduce the heat generated per unit space inside the headlight, indirectly improving the lifespan of the headlight.

[0861] In one of the optional embodiments, the projected area of ​​the light-transmitting aperture 38 in the first direction is 400 cm². 2 Then the projected area of ​​the corresponding retaining strip 37 in the first direction is no greater than 40cm². 2 That is, it can be configured as two units with an area not exceeding 20cm². 2 The baffle strip 37, for example, can be configured as a structure with a length of 10cm and a width of 2cm. It does not significantly block light relative to the light-transmitting hole 38, thus achieving the above-mentioned technical problem of indirectly improving the service life of the vehicle lamp.

[0862] Furthermore, since the aforementioned light-transmitting hole 38 has a large light-transmitting area and the baffle 37 is small and cannot produce a substantial light-blocking effect, users also have a good visual experience when viewing the vehicle lights.

[0863] In some optional embodiments, the lampshade is mirror-symmetrical with respect to a plane of symmetry. A symmetrical lampshade can reduce the difficulty of manufacturing, and its symmetrical structure can also improve the visual experience. The plane of symmetry is perpendicular to the ground, and the aforementioned first direction and vertical direction are both parallel to the plane of symmetry, i.e., the direction perpendicular to the ground.

[0864] In some optional embodiments, the number of the baffles 37 is greater than or equal to two, and the number of the light-transmitting holes 38 is the number of baffles 37 plus one. Specifically, in one optional embodiment, the number of baffles 37 is two, then the number of light-transmitting holes 38 is three, that is, two baffles 37 divide a complete large light-transmitting hole 38 into three relatively smaller light-transmitting holes 38; and the two baffles 37 are mirror-symmetrical with respect to the aforementioned plane of symmetry.

[0865] In another alternative embodiment, if the number of baffles 37 is an odd number greater than two, then at least one baffle 37 is located in the middle of the light-transmitting hole 34, that is, half of the baffle 37 located in the middle is mirror-symmetrical to the other half.

[0866] As mentioned earlier, the baffle 37 is small and cannot provide a significant light-blocking effect, meaning it only provides a small amount of light blocking. To further address the technical problem of the baffle 37 causing a decrease in visual effect or a reduction in the headlight's illumination effect due to light blocking, in one of the optional embodiments, the baffle 37 is at least partially provided with a reflective film. The reflective film has a visible light reflectivity greater than 60%, meaning the baffle 37 has a strong reflective effect. A significant amount of light illuminating the baffle 37 can be reflected back to the outside, reducing the phenomenon of weakened vehicle headlights due to the presence of the baffle 37. Furthermore, when looking at the headlights from the front of the vehicle, the reflective film at the baffle 37 can improve the continuity of the headlight's illumination, enhancing the overall visual experience.

[0867] It should be noted that the purpose of the baffle 37 is to enhance the structural stability of the lampshade; otherwise, the lampshade may have reduced strength and a shorter lifespan due to the large light-transmitting holes 34.

[0868] In one of the optional embodiments, the vehicle includes a lampshade with a light-emitting part housed inside. The lampshade includes a baffle and a light-transmitting hole for the light-emitting part to emit light forward. The ratio of the projected area of ​​the baffle to the light-transmitting hole in the front-rear direction is less than 0.1. Because the area of ​​the baffle is small and much smaller than the area of ​​the light-transmitting hole, the various light-transmitting holes appear to be almost completely connected. That is, when looking at the vehicle from the front, the visual effect is that the light-transmitting holes in the left and right directions are interconnected, and the light from left to right is close to a through-type effect, resulting in a better visual effect.

[0869] In some optional embodiments, the lampshade is at least partially made of ABS plastic, PC engineering plastic, or PMMA. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S); PC engineering plastic is a polycarbonate resin polymerized from propionol and diphenyl carbonate; and PMMA is an acrylic plastic. All of these materials possess high strength and are relatively corrosion-resistant and high-temperature resistant, therefore they are suitable as materials for the lampshade in this embodiment.

[0870] In some optional embodiments, the outer wall of the lamp cover is provided with a marking portion 27 facing the front of the vehicle. The marking portion 27 is configured with pattern information for displaying vehicle information. In some specific embodiments, referring to Figure 37, the marking portion 27 faces directly forward of the vehicle, that is, the marking portion 27 is disposed in the inner lamp cover; in other specific embodiments, the marking portion 27 is tilted forward, more specifically, in some embodiments the marking portion 27 is tilted towards the upper front of the vehicle, that is, the marking portion 27 is disposed in the outer lamp cover 2, referring to Figures 34 and 35. The aforementioned marking portion 27 is mainly used to display vehicle identification, making it easy for users to quickly identify the vehicle's brand or model, etc.

[0871] As described above, in some optional embodiments, the lampshade is configured with a marker 27 tilted upwards towards the front of the vehicle, the marker 27 being used to display vehicle identification information. Because the height of the lampshade is often lower than the head of an adult human, and the orientation of the marker 27 tilted upwards towards the front of the vehicle is closer to human eyes, it makes it easier for people near the vehicle to identify the vehicle's identification information.

[0872] In some optional embodiments, the sign surface is configured with a sign pattern. Specifically, the sign pattern can be configured as a sticker, block, or other component attached to the sign surface. To facilitate the arrangement of the sign pattern, the sign surface is generally configured as a plane or a nearly flat surface. To make the sign pattern more conspicuously visible to the user, at least one normal of the sign surface forms an angle of 15° to 75° with the ground. In a more specific embodiment, at least one normal of the sign surface forms an angle of 55° to 75° with the ground. Referring to Figure 38, which is a cross-sectional schematic diagram of the headlight assembly, line e in Figure 38 is a normal of the sign surface, line f is a line parallel to the ground, and γ is the angle between line e and line f, i.e., γ is 55° to 75°. More specifically, in one optional embodiment, the angle between the normal of the sign surface and the ground is 65°, i.e., γ = 65°.

[0873] Furthermore, in one embodiment, the marking section 27 is configured as a transparent section capable of displaying vehicle identification information. The light-emitting section disposed within the lampshade emits light towards the transparent section. That is, in this embodiment, the transparent section serves as the main component on the marking surface used to display vehicle identification information. At least a portion of the light emitted by the light-emitting section illuminates the transparent section, making it more conspicuous and better displaying the vehicle identification information. Moreover, the light transmitted through the marking section 27 also improves the vehicle's recognizability. Referring to Figure 38, the outer lampshade 2 in the figure is equipped with marking LED beads 37 that emit light towards the transparent section.

[0874] In some optional embodiments, the vehicle's headlight assembly has a marking surface with markings displaying information such as the vehicle model and brand, making it easily noticeable and memorable to the user when they see the vehicle. Furthermore, in this disclosure, the marking surface is angled upwards, meaning it faces the user's eyes directly, making it even easier to observe and notice.

[0875] In another optional embodiment, this specification also discloses a multi-functional garden vehicle, which includes a frame 1, an outdoor working component, a light-emitting unit 35, and a lampshade as described above; wherein the frame 1 extends generally along a first direction; the outdoor working component is configured as a garden working component, more specifically, the garden working component is configured as a mower 4 mounted to the frame 1 for performing lawn mowing operations. The multi-functional garden vehicle also includes a user platform, which is configured on the frame 1 and used to carry a user; specifically, in one more specific embodiment, the user platform is a seat 5 for the user to sit on and operate the lawnmower. In another more specific embodiment, the user platform is a standing platform for the user to stand on and operate the lawnmower.

[0876] The lamp cover is mounted on the frame 1 and is used to house the light-emitting part. The lamp cover includes at least two light-transmitting holes 38 located at the front and at least one baffle 37 for separating each light-transmitting hole 38. The light from the light-emitting part is projected onto the front of the vehicle through the light-transmitting holes 38. The sum of the areas of each light-transmitting hole 38 projected along a first direction is S1, and the area of ​​the at least one baffle 37 projected along the first direction is S2. The ratio of S2 to S1 is less than 0.1.

[0877] In another alternative embodiment, this specification also discloses a ride-on lawnmower, which includes a frame 1, a gardening component, a user platform, a light source, and a lampshade as described above. The gardening component is configured as a cutter head 4 mounted to the frame 1 for performing lawnmowing operations. The user platform is a seat 5 for a user to sit on and operate the lawnmower.

[0878] The lamp cover is mounted on the frame 1 and is used to house the light-emitting part. The lamp cover includes at least two light-transmitting holes 38 located at the front and at least one baffle 37 for separating each light-transmitting hole 38. The light from the light-emitting part is projected onto the front of the vehicle through the light-transmitting holes 38. The sum of the areas of each light-transmitting hole 38 projected along a first direction is S1, and the area of ​​the at least one baffle 37 projected along the first direction is S2. The ratio of S2 to S1 is less than 0.1.

[0879] This embodiment discloses a multi-functional work vehicle. Referring to Figure 1, it includes a frame 1 and an outdoor work component. The frame 1 extends along a first direction, which is also the front-rear direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work.

[0880] The multi-functional work vehicle in this embodiment also includes a headlight assembly configured on the frame 1 and used to emit light in front of the vehicle. Further, the headlight assembly includes an illumination element and a light-transmitting part, and the light emitted by the illumination element is projected in front of the vehicle through the light-transmitting part.

[0881] The area of ​​the light-transmitting portion projected along the first direction is 100 cm². 2 ~600cm 2 .

[0882] The headlight assembly emits light outward through the light-transmitting part within the projected area, which allows the headlight assembly to have a relatively better visual experience, especially when viewed from directly in front of the vehicle, where the light-transmitting part occupies most of the headlight assembly area, resulting in a better visual experience.

[0883] In some optional embodiments, the headlight assembly includes an illuminant that emits light, the illuminant including a light source and a headlight cover 32 that is at least partially transparent, the light from the light source being directed toward the front of the vehicle through the transparent portion of the headlight cover 32, the transparent portion of the headlight cover 32 having a projected area of ​​100 cm² along a first direction. 2 ~600cm 2 .

[0884] In some optional embodiments, the lighting element includes a light source, a front lamp cover 32, and a front lamp holder 31, wherein the front lamp holder 31 and the front lamp cover 32 together form a sealed space for accommodating the light source.

[0885] Referring to Figures 19 and 11, in one of the optional embodiments, the headlight assembly includes an outer lamp cover 2 and an illumination element. The light source of the illumination element includes a left lamp 317, a right lamp 316, and a daytime running light 318. That is, the light emitted by the left lamp 317, the right lamp 316, and the daytime running light 318 when they are powered on is directed toward the front of the vehicle through the headlight cover 32.

[0886] In some specific embodiments, the headlight cover 32 is configured to be partially transparent, meaning that the headlight cover 32 includes a non-transparent portion. In this embodiment, the area of ​​the headlight cover 32 as a whole projected in the first direction is larger than the area of ​​the transparent portion projected in the first direction; that is, the area of ​​the transparent portion, which is part of the headlight cover 32, projected along the first direction is 100 cm². 2 ~600cm 2 .

[0887] In another specific embodiment, referring to Figure 39, the headlight cover 32 is configured to be entirely transparent, meaning the headlight cover 32 does not include any non-transparent portions. In this embodiment, the area of ​​the entire headlight cover 32 projected in the first direction is equal to the area of ​​the transparent portion projected in the first direction; that is, the area of ​​the headlight cover 32 projected along the first direction is 100 cm². 2 ~600cm 2 Figure 39 is a front view of the headlight cover 32. The shaded area in the figure is the projection of the transparent part in the first direction in this embodiment, that is, the shaded area is the projected area of ​​the transparent part in the first direction. As shown in the figure, the shaded area occupies most of the front area of ​​the headlight assembly, that is, the headlight assembly emits light from the entire transparent part outward, thus having a better visual effect.

[0888] In one embodiment of this specification, the headlight assembly includes an illumination element and a light-transmitting portion, and the light-transmitting portion has a depth of at least 100 cm. 2 The area of ​​the headlight assembly is designed to provide a good visual experience, effectively enhancing the vehicle's frontal visual appeal. Especially for elongated light-transmitting sections, those of this size create a continuous light effect from left to right, resulting in an even better visual experience.

[0889] In some optional embodiments, the headlight cover 32 includes only one transparent portion, that is, the number of transparent portions of the headlight cover 32 is one. In this embodiment, the area of ​​the transparent portion of the headlight cover 32 projected along the first direction is 200 cm². 2 ~500cm 2 Furthermore, in one specific embodiment, the area of ​​the transparent portion of the headlight cover 32 projected along the first direction is 350 cm². 2 ~450cm 2 Referring again to Figure 39, the transparent portion extends from left to right, giving it a visual effect that runs from left to right.

[0890] In one of the optional embodiments, referring to Figure 37, the headlight cover 32 includes only two or more transparent portions. Specifically, each pair of adjacent transparent portions is separated by a non-transparent strip 37, and the strip 37 should be small and not significantly affect the actual light emission effect of the headlight assembly. Furthermore, the strip 37 should be provided with a coating, which should have a visible light reflectance of at least 60%, so as to avoid a significant splitting of the light emitted by the headlight assembly when viewed from the front, that is, to maintain the through-type visual effect of the headlight assembly due to the large transparent portion.

[0891] In some optional embodiments, the headlight assembly includes an outer lamp cover 2 that at least partially houses a lighting lamp. In this embodiment, the outer lamp cover 2 is fixedly mounted on the vehicle frame 1, and the lighting lamp is fixedly mounted on the outer lamp cover 2. The outer lamp cover 2 includes a light-transmitting aperture for light to pass through. The area of ​​the light-transmitting aperture projected along a first direction is greater than or equal to the area of ​​the transparent portion of the headlight cover 32 projected along the first direction. That is, the area of ​​the outer contour of the outer lamp cover 2 projected along the first direction is greater than or equal to the area of ​​the transparent portion of the headlight cover 32 projected along the first direction.

[0892] In some optional embodiments, the number of light-transmitting holes is one, that is, the light-transmitting holes are a single, relatively continuous structure that does not obstruct the transparent portion. Based on this part of the embodiments, one specific embodiment is that the number of transparent portions of the headlight cover 32 is one; another specific embodiment is that the number of headlight covers 32 is greater than or equal to two.

[0893] In another optional embodiment, the number of light-transmitting holes is greater than or equal to two. That is, to ensure the structural stability of the light-transmitting holes and prevent deformation during long-term vehicle use, a support member is provided on the outer lamp cover 2 to divide the light-transmitting holes into multiple parts and provide support for them. Referring to Figure 35, the support member in the figure is configured as a third baffle 373 and a fourth baffle 374 disposed on the outer lamp cover 2. As mentioned above, these support members should have a coating, similar to the aforementioned baffle 37, so as not to affect the through-type visual effect of the headlight assembly.

[0894] In some optional embodiments, the lighting includes a left lighting lamp 317 and a right lighting lamp 316, both of which illuminate the front of the vehicle through the transparent portion of the front lamp cover 32.

[0895] This embodiment discloses a multi-functional work vehicle. Referring to Figure 1, it includes a frame 1, an outdoor work component, and a headlight assembly (i.e., a headlight 3). The frame 1 extends along a first direction, which is also the front-rear direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The headlight assembly is disposed on the front side of the frame 1 and is used to emit light in front of the vehicle.

[0896] In some optional embodiments, the headlight assembly includes a left lamp section and a right lamp section connected to each other. The left lamp section houses a left illumination lamp 317, and the right lamp section houses a right illumination lamp 316. The headlight assembly as a whole has a dumbbell-shaped structure, smaller in the middle and larger at both ends. In this embodiment, the left and right lamp sections are connected to form a single unit, and its dumbbell shape facilitates gripping: users can relatively easily grip the smaller middle section of the headlight assembly. Especially during production and assembly, the slightly larger left and right lamp sections at both ends are not easy to hold with one hand, while the smaller middle section simplifies assembly, thereby improving assembly efficiency and reducing production costs.

[0897] Referring to Figures 1 and 2, in one of the optional embodiments, the multi-functional work vehicle further includes an outer lamp cover 2 disposed on the frame 1, and the headlight assembly is fitted with the outer lamp cover 2.

[0898] Furthermore, the dumbbell-shaped structure of the headlight assembly, which is larger on both sides and smaller in the middle, makes its shape more similar to the structure of human eyes. The left headlight 317 and right headlight 316 resemble human eyes, while the smaller section in the middle of the headlight assembly resembles the space between human eyes, making the headlight assembly more aesthetically pleasing. In particular, the headlight assembly provides a better visual experience when illuminated.

[0899] In some optional embodiments, the headlight housing 31 is connected to a decorative frame (i.e., the aforementioned headlight main body connector 33) located within a sealed space. The decorative frame includes lamp holes through which light from the left headlight 317 and right headlight 316 passes. Specifically, the decorative frame is at least partially coated with a coating that has a high reflectivity, enabling it to better reflect light emitted onto the decorative frame outwards. Inevitably, some light from the left headlight 317 and right headlight 316 will shine onto the edges of the lamp holes, and the edges of the lamp holes will also reflect the light outwards. When viewed from the front of the vehicle, the headlight assembly appears to emit light outwards from the decorative frame. In other words, both the headlights and the decorative frame of the headlight assembly appear to emit light outwards, giving the impression that the headlight assembly has a large luminous area and improving its visual effect.

[0900] Referring to Figure 40, a decorative frame is shown in one embodiment. The decorative frame includes a left decorative hole 331 and a right decorative hole 332. The light from the left lamp 317 shines towards the front of the vehicle through the left decorative hole 331, and the light from the right lamp 316 shines towards the front of the vehicle through the right decorative hole 332.

[0901] Referring to Figures 40 and 40A, in one of the optional embodiments, the two lamp holes of the decorative frame are symmetrical, that is, the left decorative hole 331 and the right decorative hole 332 in Figure 8 are symmetrically arranged; and the side of the inner wall of the two lamp holes that is close to each other includes a first hole surface 334 and a second hole surface 335, the intersection line of the first hole surface 334 and the second hole surface 335 of one of the lamp holes is an inner convergence line, and the closest point of one of the lamp holes to the other lamp hole is located on the inner convergence line.

[0902] In one of the optional embodiments, the side of the two lamp holes that is far apart from each other includes a third hole surface 336 that is not perpendicular to the ground. The lamp holes also include an upper hole surface 337 and a lower hole surface 338. The first hole surface 334, the second hole surface 335, the upper hole surface 337, the third hole surface 336, and the lower hole surface 338 are connected end to end in sequence to form a non-circular annular space.

[0903] In some optional embodiments, the intersection line of the third hole surface 336 with the upper hole surface 337 or the lower hole surface 338 is an outer converging line, and the farthest point of one of the lamp holes from the other lamp hole is located on the outer converging line.

[0904] As mentioned earlier, the two headlights have a visual effect similar to that of the human eye. The closest point of the two light holes resembles the inner corner of the human eye, while the farthest point resembles the outer corner. This makes the headlight assembly visually more like human eyes. Furthermore, the light holes are composed of multiple surface-mounted, non-circular annular spaces, further enhancing the sharp visual effect and providing a better visual experience.

[0905] In some optional embodiments, the headlight assembly further includes a daytime running light 318 located between the left headlight 317 and the right headlight 316. Since the headlight assembly is dumbbell-shaped, the daytime running light 318 located in the middle has a smaller dimension in the vertical direction of the vehicle than the left headlight 317 and the right headlight 316.

[0906] In some optional embodiments, the decorative bracket 36 further includes a central decorative hole 333 through which the light from the daytime running lights 318 passes. The side wall of the central decorative hole 333 is inclined near one of the light holes, resulting in unequal lengths of the upper and lower walls of the central decorative hole 333. Further, in one specific embodiment, the dimension of the upper wall of the central decorative hole 333 along the vehicle width direction is smaller than the dimension of the lower wall of the central decorative hole 333 along the vehicle width direction, meaning the central decorative hole 333 has a structure that is smaller at the top and larger at the bottom. Correspondingly, the left and right edges of the central decorative hole 333 are located below the aforementioned inner converging line, thereby reducing the distance between the central decorative hole 333 and the left and right side light holes, and thus reducing the distance between the daytime running lights 318 and the left and right headlights 317 and 316. When the daytime running lights 318, left headlight 317, and right headlight 316 of the headlight assembly are all lit, the visual effect is that the spacing between the daytime running lights 318, left headlight 317, and right headlight 316 is closer, and the light of the entire headlight assembly is closer to a continuous light effect. In other words, the visual effect of the headlight assembly when it is lit is very continuous from left to right, and there is no obvious area where the light is broken in the left and right directions.

[0907] In some optional embodiments, the aforementioned lighting main body connector 33 is configured as a decorative frame, that is, the lighting main body connector 33 not only has the aforementioned technical effect of connecting the left light, right light and daytime running light, but also has the technical effect of improving the visual experience.

[0908] In some optional embodiments, the lighting fixture includes a light-emitting panel and a reflective tile, the light-emitting panel being configured with lighting lamps that emit light toward the reflective tile; the angle between the light-emitting panel and the ground is 0–20°. In a more specific embodiment, the angle between the light-emitting panel and the ground is 0–10°, that is, the lighting lamps disposed on the surface of the light-emitting panel emit light upwards or downwards.

[0909] It should be further noted that the lighting in this application is applied to a vehicle, which needs to illuminate a certain width of area in front during operation. This means the light emitted by the lighting is not perfectly parallel. The reflector should uniformly reflect the light from the lighting bulbs to a certain width of area in front of the vehicle. Based on optical principles, to achieve a noticeable focusing effect, the reflector needs a certain width in the lateral direction and depth in the front-rear direction. In this application, the light-emitting panel is configured at a near-horizontal angle (i.e., the angle between the reflector and the horizontal is small), allowing the reflector to be positioned above or below the light-emitting panel. This means the light-emitting panel does not occupy the front-rear space of the reflector. In a vehicle where the total space occupied by the lighting is relatively limited, this configuration improves the focusing effect of the reflector under the existing conditions. In other words, compared to existing technologies, it reduces the size of the lighting while maintaining the original lighting effect, thus controlling the overall vehicle size. In summary, the garden vehicle in this application has better lighting performance, allowing for effective observation of the surrounding environment at night, facilitating effective nighttime operations.

[0910] In some specific embodiments, the illumination beads are disposed on the lower wall of the light-emitting panel and emit light at an angle downwards. The reflector is disposed below the light-emitting panel and reflects the light from the illumination beads, thus focusing the light emitted by the beads onto the front of the vehicle to achieve the purpose of illuminating the front of the vehicle. Because the lights are disposed on the vehicle frame 1, and the height of the vehicle frame 1 is relatively low, significantly below the user's head, when the user stands in front of the vehicle and looks at the headlights, the user, being at a higher position, cannot see the illumination beads; instead, the user sees only the highly consistent reflector. Conversely, if the illumination beads were disposed behind or below the reflector, they would be directly visible to the user, resulting in a poorer visual effect as the user would see both the reflector and the illumination beads.

[0911] In some specific embodiments, the upper part of the reflective tile has a light-entry hole, and the lighting bulb corresponds vertically to the light-entry hole. The light from the lighting bulb shines onto the reflective tile through the light-entry hole. Specifically, the upper part of the reflective tile is provided with an upper plate, the light-entry hole is opened on the upper plate, and the light-emitting plate is disposed above the upper plate. The lower wall of the upper plate is also provided with a coating with a strong reflective effect. The coating on the upper plate can reflect the light reflected to the upper plate downwards to the concave surface of the reflective tile, thereby reducing light consumption inside the lighting bulb and improving the brightness of the lighting bulb.

[0912] Referring to Figure 41, the upper parts of the left reflective tile 3172 and the right reflective tile 3162 include an upper left plate 31721 and an upper right plate 31621, respectively. Furthermore, the upper left plate 31721 and the upper right plate 31621 are respectively provided with a left light inlet hole 31722 and a right light inlet hole 31622. The left illumination lamp at the left light-emitting plate 3171 shines on the left reflective tile 31722 through the left light inlet hole 31722, and the right illumination lamp at the right light-emitting plate 3161 shines on the right reflective tile 3162 through the right light inlet hole 31622.

[0913] In some specific embodiments, the upper surface of the upper plate is not parallel to the lower surface of the light-emitting plate. Referring to Figure 42, there is a gap between the lower surface of the right light-emitting plate 3161 and the upper plate (upper right plate 31621) of the right reflective tile 3162. That is, the lower surface of the light-emitting plate is not attached to the upper surface of the upper plate, creating a gap between them. This gap allows the air heated by the lighting beads on the lower surface of the light-emitting plate to flow to other parts of the lighting lamp through the gap, facilitating the rapid conduction of heat from the lighting beads to the outside and preventing the lifespan of the lighting lamp from being affected by excessively high temperatures.

[0914] In one specific embodiment, the lighting lamp is equipped with at least two lighting beads, and the inner wall of the reflector is provided with a forward-protruding partition 3163. The partition 3163 is located between two adjacent lighting beads, and the partition 3163 has a blocking effect on the light from the two adjacent lamp beads. Referring to Figures 9 and 41, the reflector in the figures is equipped with three partitions 3163, and four lighting beads are arranged on the light-emitting plate. The three partitions 3163 divide the reflector into approximately four parts. The light from the four lighting beads is mainly reflected outward through the four parts of the reflector, thereby making the light reflected outward from the reflector relatively uniform, that is, the light shining in front of the vehicle is uniform, and the brightness of the area illuminated by the vehicle is relatively uniform.

[0915] In one of the optional embodiments, the multi-functional work vehicle includes a frame 1, an outdoor work component, and a headlight assembly; the frame 1 extends along a first direction, which is also the front-rear direction of the vehicle, wherein the outdoor work component is disposed on the frame 1 and is used to perform outdoor work, and the headlight assembly is disposed on the front side of the frame 1 and is used to emit light in front of the vehicle.

[0916] The headlight assembly of the multi-functional work vehicle in this embodiment includes a headlight and a daytime running light 318. The headlight is disposed on the front side of the frame 1 and is used to illuminate the front of the vehicle. The daytime running light 318 is disposed on the front side of the frame 1 and is used to improve the visibility of the vehicle.

[0917] The number of daytime running lights and / or illumination lights is greater than one, and the daytime running lights and illumination lights are arranged in at least one of the following two positional relationships:

[0918] Positional relationship one is: the number of daytime running lights is greater than one, and at least one of the lighting lights is located between two of the daytime running lights;

[0919] Positional relationship two is: the number of the lighting lamps is greater than one, and at least one of the daytime running lights is located between two of the lighting lamps.

[0920] In some optional embodiments, the headlight assembly is mirror-symmetrical with respect to a plane of symmetry that is perpendicular to both the ground and a second direction. As described above, the daytime running lights 318 and the headlight assembly together form the headlight assembly (i.e., headlight section 3), meaning that the daytime running lights 318 and the headlight assembly are generally symmetrical.

[0921] In some optional embodiments, the multi-functional work vehicle includes two headlights and at least one daytime running light 318: a left headlight 317 and a right headlight 316, with the at least one daytime running light 318 located between the left headlight 317 and the right headlight 316. Further, in some more specific embodiments, a daytime running light 318 is disposed between the left headlight 317 and the right headlight 316, and this daytime running light 318 is mirror-symmetrical with respect to the aforementioned plane of symmetry, i.e., the plane of symmetry is located at the center of the daytime running light 318, and the left headlight 317 and the right headlight 316 are also mirror-symmetrical with respect to the aforementioned plane of symmetry. In another more specific embodiment, two daytime running lights 318 are disposed between the left headlight 317 and the right headlight 316, and these two daytime running lights 318 are mirror-symmetrical with respect to the aforementioned plane of symmetry, and the left headlight 317 and the right headlight 316 are also mirror-symmetrical with respect to the aforementioned plane of symmetry.

[0922] In some optional embodiments, referring to Figures 2, 18, and 19, the headlight assembly further includes a headlight base 31 and a headlight cover 32, wherein the headlight cover 32 and the headlight base 31 cooperate to form an accommodating space for accommodating the headlight and daytime running lights 318.

[0923] In summary, the alternating configuration of daytime running lights 318 and headlights in the headlight assembly of the multi-functional work vehicle disclosed in this manual provides a better visual effect.

[0924] In some optional embodiments, the ratio of the sum of the dimensions of the daytime running lights 318 and the headlights in the second direction to the dimension of the frame 1 in the second direction is 0.5 to 1.5. Specifically, referring to Figure 43, this is g / (h+i) = 0.5 to 1.5. In some specific embodiments, the daytime running lights 318 and the headlights do not overlap in the second direction; in other specific embodiments, the daytime running lights 318 and the headlights overlap in the second direction; however, the overlapping portion in the second direction should conform to a staggered vertical position to avoid the light from the daytime running lights 318 or the headlights being blocked by the other. Referring to Figure 43, the daytime running lights 318 in the figure have a small overlap in the second direction.

[0925] Furthermore, the portion where the sum of the dimensions of the daytime running lights 318 and the headlights in the second direction is 1 to 1.5 of the dimension of the frame 1 in the second direction necessarily means that the daytime running lights 318 and the headlights overlap in the second direction.

[0926] In one of the optional embodiments, referring to Figure 3, the light-emitting element includes two headlights and at least one daytime running light 318, the at least one daytime running light 318 being located between the two headlights. At least two headlights are located on the left and right sides of the vehicle to illuminate the front of the vehicle from both sides, resulting in better lighting effect. Smaller objects cannot simultaneously block both headlights, thus ensuring good lighting performance.

[0927] In some optional embodiments, the daytime running light 318 includes a first lamp 31811, and the lighting lamp includes a focusing part and lighting lamps that emit light toward the focusing part. The focusing part is used to refract or reflect the light from the lighting lamps so that the light is closer to parallel light, thereby producing a stronger lighting effect at a greater distance in front of the vehicle.

[0928] In some optional embodiments, the distance between the focusing part and the nearest first LED bead 31811 along the second direction is 0-80mm, referring to Figure 44, i.e., L1 in the figure is 0-80mm. Looking at the headlights from the front of the vehicle, the visual effect is that the light from the headlights is emitted forward from the reflector; the light from the daytime running lights 318 is emitted forward from the first LED bead 31811. The closer distance between the first LED bead 31811 and the reflector makes the light appear more continuous, exhibiting a through-type light effect with a stronger visual impact. A distance of less than 80mm is sufficient to achieve this continuous light effect. Further, in some optional embodiments, the distance between the reflector and the nearest first LED bead 31811 along the second direction is 10mm-40mm. This smaller distance further enhances the visual continuity and improves the through-type light effect.

[0929] In one of the optional embodiments, referring to Figure 44, the illumination bulb is configured to emit light generally downwards, that is, the illumination bulb is located above the reflector. Since the height of the headlight assembly is generally lower than the height of an adult human, when a user stands in front of the vehicle, they cannot see the inner upper wall of the headlight assembly; that is, the user cannot directly see the illumination bulb, but can only see the nearly parallel light emitted after reflection by the reflector. Conversely, if the user could directly see the illumination bulb, the light seen by the user would necessarily include the light directly emitted by the illumination bulb and the light reflected by the reflector, resulting in poor uniformity of the light seen at various points, that is, a slightly worse visual effect.

[0930] In one of the optional embodiments, the distance between one of the illumination beads and the nearest first lamp bead 31811 along the second direction is 0 to 100 mm. Referring again to Figure 44, L2 in the figure is 0 to 100 mm. Since the illumination beads do not need to be positioned at the outermost edge of the reflector, the distance between the illumination bead near the daytime running light 318 and the nearest first lamp bead 31811 is greater than the distance between the reflector and the nearest first lamp bead 31811.

[0931] In some optional embodiments, the multi-functional work vehicle further includes a headlight cover 32 and a headlight base 31 that are combined to form a sealed space, with the light-emitting element disposed within the sealed space. That is, the daytime running lights 318 and the headlights are both located in the same sealed space, and there is no physical structure separating the daytime running lights 318 and the headlights in space. In other words, there is no problem affecting the continuous effect of the light beams of the daytime running lights 318 and the headlights, ensuring that the headlight assembly has a good through-type visual effect.

[0932] In some optional embodiments, the headlight assembly (headlight section 3) of the multi-functional work vehicle, which houses the luminous lamps and daytime running lights, is collectively referred to as light-emitting elements. In this embodiment, the headlight assembly includes at least two light-emitting elements, which are disposed on the front side of the frame 1 and used to emit light forward toward the vehicle. Further, the minimum distance between any two adjacent light-emitting elements along a second direction is 0-50 mm, where the second direction is the width direction of the vehicle. Due to the small distance between each adjacent light-emitting element, the headlight assembly as a whole appears closer to a relatively continuous component. Especially when all light-emitting elements are emitting light, the continuous light gives it a through-type lighting effect, resulting in a better visual effect.

[0933] In some optional embodiments, the at least two light-emitting elements include a headlight and a daytime running light 318. The headlight illuminates the area in front of the vehicle, and the daytime running light 318 illuminates the area in front of the vehicle and enhances its visibility. That is, the headlight and the daytime running light 318 primarily serve different functions: illuminating the area and enhancing vehicle visibility, respectively.

[0934] Furthermore, in one of the optional embodiments, referring to Figure 11, as shown, the at least two light-emitting elements include a left illumination lamp 317, a daytime running lamp 318, and a right illumination lamp 316 arranged sequentially in a second manner.

[0935] In some optional embodiments, the headlight assembly includes electrically emitting LEDs, meaning that both the headlight and daytime running lights 318 are equipped with electrically emitting LEDs, and the distance between the two furthest LEDs along the second direction is 250mm to 1100mm. This means the headlight assembly has a relatively wide outward emitting area in the left-right direction, and the wider and more continuous light makes it appear to have a more continuous lighting effect, resulting in a better visual effect.

[0936] In some optional embodiments, the light-emitting element includes two headlights and at least one daytime running light 318, the at least one daytime running light 318 being located between the two headlights. The at least two headlights are located on the left and right sides of the vehicle, at least approximately symmetrically, illuminating the front of the vehicle from both sides, resulting in better lighting effect. Smaller objects cannot simultaneously block both headlights, thus ensuring good lighting performance.

[0937] In some optional embodiments, the daytime running light 318 includes a first lamp 31811, and the lighting lamp includes a focusing part and lighting lamps that emit light toward the focusing part. The focusing part is used to refract or reflect the light from the lighting lamps so that the light is closer to parallel light, thereby producing a stronger lighting effect at a greater distance in front of the vehicle.

[0938] In one of the more specific embodiments, referring to Figure 45, the right light 316 includes a right light bulb 31611, the left light 317 includes a right light bulb 31711, and the daytime running light 318 includes a first light bulb 31811. L3 in the figure is the distance between the leftmost right light bulb 31611 and the rightmost right light bulb 31711. In this embodiment, it is also the distance between the two farthest light bulbs along the second direction, which is L3, which is 250mm to 1100mm.

[0939] Referring again to Figures 3 and 4, the daytime running light 318 in the figures includes a central lamp plate 3181 and a central lamp cover 3182. The first lamp bead 31811 array is disposed on the central lamp plate 3181, and the central lamp cover 3182 is disposed on the central lamp plate 3181.

[0940] Referring to Figure 45, in one embodiment, the focusing part is configured as a reflective tile as shown in the figure. Specifically, the left light lamp 317 includes a left reflective tile 3172, and the right light lamp 316 includes a right reflective tile 3162. The reflective tile has a coating on the side near the light bulb, which has a strong reflective effect. At the same time, the reflective tile has a bowl-shaped concave surface. The light emitted by the light bulb is reflected by the concave surface to form a nearly parallel light beam that shines forward, thereby producing a stronger lighting effect for a longer distance in front of the vehicle.

[0941] In some optional embodiments, the distance between the focusing part and the nearest first LED bead 31811 along the second direction is 0-80mm. Looking at the headlights from the front of the vehicle, the visual effect is that the light from the headlights is emitted forward from the reflector; the light from the daytime running lights 318 is emitted forward from the first LED bead 31811. The closer distance between the first LED bead 31811 and the reflector makes the light appear more continuous, thus exhibiting a through-type light effect with a stronger visual impact. A distance of less than 80mm is sufficient to achieve this continuous light effect. Further, in some optional embodiments, the distance between the reflector and the nearest first LED bead 31811 along the second direction is 10mm-40mm. This smaller distance further enhances the visual continuity and improves the through-type light effect.

[0942] Referring to Figure 44, the distance L1 between the rightmost first LED 31811 and the right reflector 3162 is shown. As mentioned above, L1 is 0–80 mm. In particular, in some embodiments, L1 is 10 mm–40 mm.

[0943] Referring to Figure 45, the right LED 31611 of the right illuminator 316 is shown.

[0944] In some optional embodiments, the illumination bulb is configured to emit light generally downwards, meaning the bulb is located above the reflector. Since the headlight assembly is generally shorter than an adult human, when a user stands in front of the vehicle, they cannot see the inner upper wall of the headlight assembly; that is, the user cannot directly see the illumination bulb, but only the nearly parallel light emitted after reflection from the reflector. Conversely, if the user could directly see the illumination bulb, the light they see would necessarily include both the light directly emitted by the bulb and the light reflected by the reflector, resulting in poor uniformity of the light seen at different points, and thus a slightly inferior visual effect.

[0945] In one of the optional embodiments, the distance between one of the lighting beads and the nearest first lamp bead 31811 along the second direction is 0 to 100 mm. Since the lighting beads do not need to be arranged at the outermost edge of the reflector, the distance between the lighting beads near the daytime running light 318 and the nearest first lamp bead 31811 is greater than the distance between the reflector and the nearest first lamp bead 31811.

[0946] Referring to Figure 44, the distance between the rightmost first LED 31811 and the nearest right LED 31611 is L2, as described above, L2 is 0 to 100 mm.

[0947] In some optional embodiments, the multi-functional work vehicle further includes a headlight cover 32 and a headlight base 31 that are combined to form a sealed space, with the light-emitting element disposed within the sealed space. That is, the daytime running light 318 and the two headlights are all located in the same sealed space, and there is no physical structure separating the daytime running light 318 and the headlights in space. In other words, there is no problem affecting the continuous effect of the light beams of the daytime running light 318 and the headlights, further ensuring that the headlight assembly has a good through-type visual effect.

[0948] In some optional embodiments, the headlight cover 32 is at least partially configured as a transparent portion, through which the daytime running lights 318 and the headlights are emitted outward. The projection of the light-emitting element in a first direction is located within the projection of the transparent portion in the first direction. That is, the non-transparent portion of the headlight cover 32 is avoided as much as possible from blocking the light from any light-emitting element, thereby improving the utilization rate of light.

[0949] Furthermore, the daytime running light 318 serves to improve vehicle visibility; therefore, it needs to emit light in all directions as much as possible. This means that a focusing part should not be positioned in front of the daytime running light 318 to create a converging effect on the light. Conversely, the headlights have a focusing part so that their light beams are mostly parallel and emitted forward. In other words, when viewed from the front of the vehicle, the edge of the transparent part, close to the edge of the headlight, will not obstruct the headlight's light. Furthermore, the daytime running light 318 is positioned between the two headlights, and its light emitted to both sides can be projected outwards through the transparent part in front of the headlights. This positioning of the daytime running light 318 between the two headlights ensures that its light is not obstructed by the non-transparent part of the headlight cover 32 to the greatest extent possible.

[0950] In one embodiment, referring to Figure 1, the multi-functional work vehicle includes a frame 1 and an outdoor work component; the frame 1 extends along a first direction, which is also the vehicle's forward direction, and the outdoor work component is disposed on the frame 1 and used to perform outdoor work. Further, referring to Figures 48 and 49, the frame 1 includes two longitudinal beams 11 extending generally along the first direction and a crossbeam 12 connecting the two longitudinal beams 11, the crossbeam 12 connecting the longitudinal beams 11 to make the overall structure of the frame 1 relatively stable.

[0951] The multi-functional work vehicle in this embodiment also includes a headlight assembly disposed on the frame 1, the headlight assembly being used to emit light forward of the vehicle. Further, referring to Figures 1, 46, and 47, the multi-functional work vehicle also includes an outer lamp cover 2 disposed on the frame 1, the headlight assembly being disposed within the outer lamp cover 2.

[0952] In some optional embodiments, the outer lamp cover 2 forms an outer cover space in which the headlight assembly is completely contained, that is, no part of the headlight assembly protrudes outward beyond the outer cover space.

[0953] In some optional embodiments, the outer lamp cover 2 forms an outer cover space, and a portion of the headlight assembly extends beyond the outer cover space, i.e., the outer cover space has an opening on at least one side, through which a portion of the headlight assembly extends to the outside.

[0954] In some optional embodiments, both the outer lamp cover 2 and the crossbeam 12 have a first threaded hole facing the front of the vehicle. The multi-functional work vehicle also includes a first bolt that passes through the first threaded hole from rear to front, through the outer lamp cover 2, and connects to the crossbeam 12 to fix the positional relationship between the outer lamp cover 2 and the frame 1. Furthermore, the first threaded hole and the first bolt do not extend to the side of the frame 1 closest to the front of the vehicle, so that when looking at the frame 1 from the front of the vehicle, the bolt or threaded hole exposed at the front of the vehicle is not visible, thereby improving the flatness of the visible surface of the vehicle and thus providing a better visual effect at that location.

[0955] In one optional embodiment, at least a portion of the crossbeam 12 is implemented as a square tube, and the first threaded hole of the crossbeam 12 is formed in one side wall of the square tube; the first threaded hole here is the crossbeam hole 121 in Figure 50. Further, the first threaded hole is formed in one side wall of the square tube near the rear of the vehicle, and the other side wall of the square tube obstructs the first threaded hole behind it, meaning the first threaded hole cannot be directly observed from the front, thus achieving the technical objective of preventing the first threaded hole or the first bolt from being exposed at the front of the vehicle.

[0956] In one alternative embodiment, the internal thread for threaded engagement with the first bolt is disposed on the inner wall of the first threaded hole of the crossbeam 12. In another alternative embodiment, a nut with internal threads may also be welded onto the crossbeam 12.

[0957] In one alternative embodiment, the first threaded hole in the crossbeam 12 is implemented as a nut with internal threads and fixed to the surface of the crossbeam 12. This embodiment does not require drilling holes in the crossbeam 12, and even if the crossbeam 12 is configured as a single-layer structure, the method of welding the nut will not cause the first bolt to be exposed in front of the crossbeam 12.

[0958] In one optional embodiment, the outer lamp cover 2 includes a lower edge 221 that covers at least part of the front of the crossbeam 12. That is, the outer lamp cover 2 includes a lower edge 221 that is located at least in front of part of the crossbeam 12. When a user views the vehicle from the front, the outer lamp cover 2 obscures the crossbeam 12, preventing the complete crossbeam 12 from being directly observed and improving the user's visual experience of the front of the vehicle.

[0959] Furthermore, in some optional embodiments, the projection of the first bolt along the first direction is located within the projection of the outer lamp cover 2 along the first direction. Even if the first bolt is misaligned, it will not be observed from the front of the vehicle. Referring to Figure 1, the position of the first bolt of the crossbeam 12 in the figure is blocked by the lower edge 221, thereby avoiding the technical problem of poor visual effect due to installation error.

[0960] In one of the optional embodiments, referring to Figure 52, the outer lamp cover 2 includes a front cover 22 and a rear cover 21, which together form a receiving space for accommodating the headlight assembly. The front cover 22 is located in front of the rear cover 21, and the front cover 22 has a light-transmitting hole for light emitted from the headlight assembly to pass through.

[0961] In some optional embodiments, the outer front cover 22 and the outer rear cover 21 are detachably fixedly connected, with the outer rear cover 21 connected to the frame 1 at least by the aforementioned first bolt. Specifically, referring to Figures 52 and 53, the first threaded hole of the outer lamp cover 2 is disposed on the outer rear cover 21.

[0962] In one of the alternative embodiments, referring to Figure 52, the lower edge 221 of the portion used to shield the crossbeam 12 is implemented as a portion of the outer front cover 22.

[0963] As described above: When the outer rear cover 21 is engaged with the frame 1 by the first bolt, it abuts against the crossbeam 12. In some optional embodiments, the outer front cover 22 also includes a downwardly extending engaging portion. The engaging portion and the portion of the outer rear cover 21 that abuts against the crossbeam 12 are located on the front and rear sides of the crossbeam 12 respectively and abut against each other, thereby achieving the initial positioning of the outer lamp cover 2 and the frame 1. The engaging portion here and the outer rear cover 21 together form a engaging portion that engages with the crossbeam 12.

[0964] In one of the optional embodiments, referring to Figures 52 and 53, the outer rear cover 21 is provided with a downwardly protruding connecting ear 211, and the connecting ear 211 has an ear hole 2111, which is the first bolt hole provided on the outer rear cover 21.

[0965] Furthermore, in some optional embodiments, the connecting ear 211 and the outer front cover 22 respectively abut against the front and rear sides of the crossbeam 12 to achieve initial positioning of the outer lamp cover 2 and the frame 1.

[0966] In some optional embodiments, the aforementioned engaging portion is the aforementioned lower edge 221, that is, the lower edge 221 of the outer front cover 22 and the outer rear cover 21 together abut against the crossbeam 12 of the frame 1 to achieve the initial positioning of the outer lamp cover 2 and the crossbeam 12.

[0967] After the initial positioning described above, the outer lamp cover 2 can be placed relatively stably on the frame 1. However, the initial positioning alone does not achieve the fixation of the outer lamp cover 2. Therefore, at least the first bolt mentioned above is required to fix the outer lamp cover 2 to the frame 1.

[0968] The above embodiment discloses that the outer front cover 22 and the outer rear cover 21 of the outer lamp cover 2 respectively form two parts of the snap-fit ​​part, which are snapped into the crossbeam 12 of the frame 1 to achieve the limiting effect. In another optional embodiment, the two parts that form the snap-fit ​​part (that is, the two parts located in front of and behind the crossbeam 12 respectively) are both located in the outer front cover 22 or the outer rear cover 21.

[0969] In some optional embodiments, the crossbeam 12 is a single-segment structure, that is, the entire crossbeam 12 is a single structure that is always perpendicular to the first direction.

[0970] In another optional embodiment, referring to Figures 48, 49, and 51, the crossbeam 12 is a multi-segment structure. That is, the crossbeam 12 is not a single structure completely perpendicular to the first direction, but is composed of multiple connected transverse beams, some of which are not perpendicular to the first direction. Referring to Figure 51, the crossbeam 12 in the figure is composed of a first beam 122, a second beam 124, and a third beam 123 connected end to end. In another optional embodiment, at least a portion of the transverse beams has an arc-shaped profile.

[0971] It should be further noted that the crossbeam 12 is composed of multiple connected horizontal beams, but this does not limit the multiple horizontal beams to being separable structures. That is, in some embodiments, the multiple horizontal beams of the crossbeam 12 are formed by bending a straight structure. In another optional embodiment, the crossbeam 12 is formed by connecting multiple separate horizontal beams through welding or other methods.

[0972] In some optional embodiments, the aforementioned snap-fit ​​portion engages with the transverse beam.

[0973] In another optional embodiment, the snap-fit ​​portion does not snap onto the crossbeam 12 of the frame 1, but rather snaps onto the longitudinal beam 11 of the frame 1. Further, the snap-fit ​​portion snaps onto one or two longitudinal beams 11 to limit the position of the outer lamp cover 2 relative to the frame 1.

[0974] In some optional embodiments, the longitudinal beam 11 or the transverse beam 12 is mainly made of square tubing, that is, the part of the frame 1 that mates with the aforementioned snap-fit ​​part is made of square tubing. Square tubing is a rectangular tube, and its relatively light weight and high strength make it a preferred material for the frame 1. It also has a significant width in the horizontal direction, which facilitates the snap-fit ​​part engaging with it.

[0975] In some optional embodiments, at least one cross-section of the latching portion is a downward-opening U-shape. That is, when the latching portion mates with the frame 1, the installation direction is from top to bottom, which is more in line with common assembly habits. Referring to Figures 55 and 56, Figure 56 is a cross-sectional view along direction E of Figure 55, where it can be clearly seen that the lower edge 221 and the connecting ear 211 together form a U-shaped structure. In other embodiments, the latching portion may also be configured as a U-shape with at least one cross-section opening facing forward, backward, left, right, or upward directions.

[0976] Further, in some optional embodiments, the snap-fit ​​portion includes three abutting surfaces that abut against the frame 1: a first abutting surface 222, a second abutting surface 223, and a third abutting surface 212. The second abutting surface 223 is located between the first abutting surface 222 and the third abutting surface 212. The first abutting surface 222 and the third abutting surface 212 abut against two opposite surfaces of the longitudinal beam 11 or the crossbeam 12, respectively, and the second abutting surface 223 abuts against the other surface of the longitudinal beam 11 or the crossbeam 12, thereby fixing the outer lamp cover 2 to the frame 1 in at least two directions. Referring to Figure 56, in this embodiment, the first abutting surface 222 and the third abutting surface 212 abut against the front and rear surfaces of the crossbeam 12, respectively, and the second abutting surface 223 abuts against the upper surface of the crossbeam 12, thereby fixing the frame 1 to the outer lamp cover 2 in the front-rear direction and the vertical direction.

[0977] In one of the optional embodiments, referring to Figure 56, as previously described, the snap-fit ​​portion is composed of an outer front cover 22 and an outer rear cover 21, and the first abutting surface 222 and the third abutting surface 212 are located on the outer front cover 22 and the outer rear cover 21, respectively.

[0978] In some optional embodiments, the outer front cover 22 and / or outer rear cover 21 are connected to the frame 1 by a first bolt. The first bolt is arranged in a first direction, that is, the first bolt is fixed in the front-rear direction. The above-mentioned snap-fit ​​portion realizes the initial positioning of the frame 1 and the outer lamp cover 2. However, the effect of this initial positioning and fixing cannot keep the vehicle from shifting during driving. Therefore, the above-mentioned first bolt is configured to form a stable connection between the outer lamp cover 2 and the frame 1.

[0979] The foregoing disclosed that the first bolt connects the outer rear cover 21 and the frame 1. In another embodiment, the first bolt connects the outer front cover...
