[0054] This embodiment discloses a multi-functional garden vehicle. Refer to the attached Figure 1 , including a frame 1 and garden operation components; wherein the frame 1 extends along a first direction, which is also the forward direction of the vehicle, and the outdoor operation components are arranged on the frame 1 and are used for performing garden operations.

[0055] The multifunctional garden vehicle in this embodiment further includes a headlight assembly 3 disposed on the frame 1, and the headlight assembly 3 is used to emit light to the front of the vehicle. Figure 1 In the figure, an outer lampshade 2 is arranged on the frame 1, and the headlight assembly 3 is arranged on the outer lampshade 2, that is, the outer lampshade 2 is mainly used to connect the headlight assembly 3 and the frame 1, and the outer lampshade 2 does not have a shielding effect on the front of the headlight assembly 3, so as to avoid affecting the luminous effect of the headlight assembly 3 on the front.

[0056] Further, see Attachment Figure 2 The headlight assembly 3 includes a headlight holder 31 and a headlight cover 32. Figure 3 , attached Figure 3 For attachment Figure 2 The headlight assembly 3 shown in the figure hides the headlight cover 32, and the headlight base 31 is provided with a vent hole 3131; Figure 4 The air hole 3131 is provided with a waterproof breathable device 313, and the headlight holder 31, the headlight cover 32, and the waterproof breathable device 313 together form a closed space, and a lighting lamp is arranged in the closed space, and the lighting lamp is used to illuminate the front of the vehicle.

[0057] In some of the optional embodiments, at least a portion of the headlight cover 32 is configured as a transparent structure, which facilitates the lighting lamp in the enclosed space to radiate light outward, thereby achieving a technical lighting effect.

[0058] In some optional embodiments, refer to the attached Figure 2 , Attachment Figure 3 The lighting lamp includes a left lighting lamp 34 and a right lighting lamp 33, and the air vent 3131 includes a left air vent 3131 and a right air vent 3131 respectively located behind the left lighting lamp 34 and the right lighting lamp 33.

[0059] In some optional embodiments, refer to the attached Figure 2 The headlight assembly 3 also includes a daytime running light 35 disposed in the enclosed space and located between the left lighting lamp 34 and the right lighting lamp 33 , and the air vent 3131 also includes a middle air vent 3131 located behind the daytime running light 35 .

[0060] In order to keep the enclosed space of the headlight assembly 3 in a well-enclosed state, a waterproof vent 313 is disposed at the left vent hole 3131 , the right vent hole 3131 , and the middle vent hole 3131 .

[0061] In some optional embodiments, the waterproof breathable device 313 includes a waterproof breathable membrane disposed at the breathable hole 3131. This prevents external water vapor from entering the enclosed space and affecting the service life of the lighting lamp, while also taking into account the breathable effect. Figure 5 ,Figure 5 is an enlarged schematic view of a partial area. For ease of understanding, in the appended Figure 4 figure, the breathable film is shown as a device separated from the ventilation holes 3131. In fact, the breathable film should be attached to the ventilation holes 3131. Figure 5 In the figure, the breathable film is shown as a device separated from the ventilation holes 3131. In fact, the breathable film should be attached to the ventilation holes 3131.

[0062] Refer to the appended Figure 5 figure, in which it is shown that the front lamp socket 31 is also provided with a wire 312 passing through it, and the vehicle body supplies power to the headlamp assembly 3 through the wire 312.

[0063] In some alternative embodiments, the porosity of the breathable film is 20% - 90%. In this embodiment, the heat generated by the lighting lamp will not be too large, nor will it cause the air in the enclosed space to expand too significantly. Therefore, the requirement for the porosity of the breathable film is not high. Generally, a breathable film with a porosity greater than 20% can meet the usage requirements; however, a higher porosity will surely enable faster air exchange. Therefore, it is also within the scope of alternatives in this embodiment. Generally, a breathable film with a porosity not higher than 90% can be selected.

[0064] The unilateral area of the breathable film at a single ventilation hole 3131 is 20mm 2 - 400mm 2 ; as described above, the heat generated by the lighting lamp will not be too large, nor will it cause the air in the enclosed space to expand significantly. However, the long-term operation of the lighting lamp will still cause a certain temperature difference between the inside and outside of the enclosed space. Therefore, when selecting a breathable film with a smaller porosity, generally a larger area of the breathable film needs to be selected; conversely, when selecting a breathable film with a larger porosity, generally a slightly smaller area of the breathable film can be selected to meet the ventilation requirements. Generally speaking, for a breathable film with a porosity of 20% - 90%, in this embodiment, a breathable film with a unilateral area of 20mm 2 - 400mm 2 can be selected. At the same time, the area of a single breathable film can also be appropriately reduced by configuring multiple breathable films and ventilation holes 3131.

[0065] It should be specifically noted that: generally, the installation method of the breathable film is gluing, that is, applying glue at the edge of the breathable film to paste it on the edge of the ventilation hole 3131. However, the part of the breathable film coated with glue cannot maintain the ventilation effect, that is, the effective ventilation area of the waterproof breathable film is smaller than its unilateral area.

[0066] In some alternative embodiments, the ratio of the area of at least one of the waterproof and breathable membranes to the area of the corresponding air vent 3131 is 2 to 8. As described above, since the part of the breathable membrane coated with glue cannot maintain the breathable effect, and considering that the waterproof and breathable membrane needs to have a good breathable effect and can be relatively firmly adhered to the air vent 3131, the area ratio of the waterproof and breathable membrane to the air vent 3131 generally satisfies 1.5 to 10. Exemplarily, in one specific embodiment, the waterproof and breathable membrane is a circular piece with a radius of 4 mm, and the air 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 and breathable membrane is a circular piece with a radius of 6 mm, and the air 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 is a circular piece with a radius of 8 mm, and the air vent 3131 is a circular hole with a diameter of 3 mm, then the area ratio of the two is approximately 7.1. In summary, the area ratio of the two generally conforms to the above range of 2 to 8.

[0067] In some alternative embodiments, an installation groove is formed in the front lamp base, the air vent 3131 and the waterproof and breathable membrane are both arranged in the installation groove, and the outer edge of the waterproof and breathable membrane does not exceed the groove wall of the installation groove. This can prevent the waterproof and breathable membrane from being displaced when the external wind or an object slides along the outer wall of the front lamp base, and further ensure the stable position of the waterproof and breathable membrane, that is, ensure its good waterproof and breathable effect.

[0068] In some alternative embodiments, the closed space jointly formed by the above-mentioned front lamp base 31, front lamp cover 32, and waterproof and breathable device 313 at least meets the IPX5 waterproof level. It should be noted that the IP (Ingress Protection) protection level system is used to classify electrical appliances according to their dust and moisture-proof characteristics; the IP protection level is composed of two numbers. The first number represents the level of dust protection and prevention of foreign objects from entering the electrical appliance. The second number represents the degree of tightness of the electrical appliance against moisture and water ingress, and the larger the number, the higher the protection level. The IPX5 waterproof level in this embodiment means that it can withstand a low-pressure water column and can withstand a water column with an inner diameter of 6.3 mm ejected from a nozzle. Meeting this waterproof level can ensure that the front lamp assembly 3 can work normally in rainy weather without abnormal conditions such as water entering the lamp cover.

[0069] Furthermore, in another alternative embodiment, the closed space meets the IPX6 waterproof level. Here, the second number is 6, indicating that the closed space meets the requirement of withstanding a strong water column and can withstand a strong water column with an inner diameter of 12.5 mm ejected from a nozzle. This can further prevent the problem of water entering the lamp cover and affecting the service life of the lighting lamp when the garden vehicle is working in rainy weather.

[0070] Further, in another alternative embodiment, the above-mentioned enclosed space meets the IPX7 waterproof level. The second digit here is 7, indicating that the enclosed space meets the requirement of being protected against temporary immersion and can withstand immersion underwater at a specified time and pressure. This can further prevent the problem that water enters the lamp housing during rainy weather when the gardening vehicle is in operation, which may affect the lifespan of the lighting lamp.

[0071] In some alternative embodiments, the front lamp base 31 and the front lamp cover 32 are respectively provided with a first fastener and an elastic second fastener. The first fastener and the second fastener cooperate to fix the front lamp cover 32 to the front lamp base 31. The combination of the first fastener and the second fastener is used for the preliminary positioning of the front lamp base 31 and the front lamp cover 32. Among them, the first fastener and / or the second fastener is elastic to facilitate installation, and after installation, the two fasteners are elastically abutted against each other to produce a certain sealing effect.

[0072] Further, in some alternative embodiments, the first fastener is configured as a protrusion 311 fixed to the front lamp base 31, and the second fastener is configured as a buckle 321 fixed to the front lamp cover 32. The buckle 321 has a clamping space that can accommodate the protrusion 311, and the protrusion 311 is accommodated in the above-mentioned clamping space when the front lamp cover 32 and the front lamp base 31 are fitted.

[0073] In some alternative embodiments, the assembly process of the front lamp base 31 and the front lamp cover 32 includes one or more of ultrasonic welding, friction welding, sealant, and elastic rubber strips. It should be particularly noted that the above are only the processes for achieving sealing between the two, and should not be limited to the understanding that the two are only connected through the above processes. For example: in one more specific embodiment, the front lamp cover 32 and the front lamp base 31 are sealed by sealant, but need to be relatively fixed in position through connectors such as buckles or bolts, and then sealant is applied to the gap between the two, that is, the gap is filled with sealant to keep the two in a sealed connection.

[0074] In some alternative embodiments, referring to Appendix Figure 2 、Appendix Figure 6 , the contour line of the contact surface between the front lamp base 31 and the front lamp cover 32 in the figure includes a relatively complex plurality of curves, rather than a relatively straight contour line. Therefore, the front lamp base 31 and the front lamp cover 32 are sealed by sealant. Further, the selected sealant is hot melt sealant. During production and manufacturing, the operation difficulty of pouring hot melt sealant along the contact surface of the front lamp cover 32 and the front lamp base 31 is slightly lower, thereby reducing the production cost.

[0075] In another part of the alternative embodiments, the contour line of the contact surface between the front lamp base 31 and the front lamp cover 32 is a regular straight line. At this time, processes such as ultrasonic welding, friction welding, and sealant strips can be selected for sealing.

[0076] In some alternative embodiments, the front lamp base 31 is provided with air vents 3131 for balancing the pressure inside and outside the sealed space, so as to avoid damaging the sealing effect due to a significant increase in pressure caused by the rise in temperature inside the sealed space. The air vents 3131 face the rear of the vehicle, reducing the possibility of external rainwater flowing to the air vents 3131.

[0077] In some alternative embodiments, referring to the appendix Figure 7 , the left lighting lamp 34 and the right lighting lamp 33 include lighting beads that emit light when energized (not shown in the figure), and the daytime running lamp 35 includes a first lighting bead 352 that emits light when energized; the lighting beads therein are mainly used to produce a lighting effect in front of the vehicle. When the ambient light is poor, the left and right lighting lamps 33 are turned on so that the user can better observe the ground conditions in front of the vehicle for better gardening operations. The daytime running lamp 35 is mainly used to improve the recognizability of the vehicle. When the vehicle is operating during the day with good lighting conditions, it is lit up to make it easily recognizable from the outside, that is, the recognizability is improved. It is convenient for people outside to quickly notice the operating vehicle that may have safety risks here and not continue to approach, thereby improving the operating safety performance of the vehicle.

[0078] In some alternative embodiments, the power of the first lighting bead 352 is less than the power of the lighting beads, and the power here is the rated power of the corresponding lighting beads.

[0079] In some alternative embodiments, the lighting lamp of the front lamp assembly 3 includes a light condensing portion and lighting beads that emit light when energized. The light emitted by the lighting beads is affected by the light condensing effect of the light condensing portion, and the illuminance at a distance of 10 meters in front of the vehicle is 10 lux to 60 lux. Within this illuminance range, the basic lighting requirements can be met; in another part of the alternative embodiments, the light intensity generated by the lighting assembly at a distance of 10 meters in front of the multi-functional gardening vehicle is 20 lux to 40 lux. In another part of the alternative embodiments, the light intensity generated by the lighting assembly at a distance of 10 meters in front of the multi-functional gardening vehicle is 25 lux to 35 lux. It is used to meet the lighting within 10 meters in front, facilitating the user to timely obtain the ground conditions within 10 meters in front of the vehicle. More specifically, in one of the embodiments, the light intensity generated by the integrated front headlamp assembly at a distance of 10 meters in front of the multi-functional operation vehicle is 30 lux.

[0080] Referring to the appendix Figure 11 , the figure shows a schematic diagram of the front lamp assembly 3 emitting light towards the front of the vehicle. The lights of the left lighting lamp 34 and the right lighting lamp 33 in the figure coincide at a distance of X in the front, so that the left lighting lamp 34 and the right lighting lamp 33 jointly achieve sufficient lighting of the coincident position. In some specific embodiments, X is 10 meters, and the front headlamp generates a light intensity of 30 lux at the light coincidence position at this 10-meter distance.

[0081] In some alternative embodiments, the light condensing part is configured as a lens and / or a reflector tile, and the lighting lamp beads emit light towards the light condensing part. In some of these alternative embodiments, a convex lens facing the front of the vehicle is selected as the light condensing part, which has the effect of gathering the divergently irradiated light to irradiate only forward. In some other alternative embodiments, a reflector tile is selected as the light condensing part. A coating is arranged on one side of the reflector tile close to the lighting lamp beads. The coating has a strong light reflection effect. At the same time, the reflector tile has a bowl-shaped concave surface. The light emitted by the lighting lamp beads is reflected by the concave surface to form light that is nearly parallel and irradiates forward, so as to be able to produce a stronger lighting effect on a relatively far distance in front of the vehicle.

[0082] In some alternative embodiments, in order to simplify the assembly, the lighting lamp includes a light emitting plate, and the lighting lamp beads are arranged on the light emitting plate. Specifically, referring to the appendix Figure 8 , the right lighting lamp 33 includes a right light emitting plate 331 and a right reflector tile 332 as the light condensing part, and the left lighting lamp 34 includes a left light emitting plate 341 and a left reflector 342 as the light condensing part.

[0083] In some of these alternative embodiments, referring to the appendix Figure 9 , the left light emitting plate 341 is not parallel to the right light emitting plate 331. In some of these alternative embodiments, both light emitting plates are inclined towards the middle position in the left-right direction, that is, the light emitting plates are biased towards the middle position for lighting, so that the light has a slightly inclined angle of gathering towards the middle. This is convenient for the lights of the two lighting lamps to overlap in front of the vehicle to achieve a stronger lighting effect.

[0084] Specifically, in some more specific embodiments, the lighting lamp beads are located on the upper wall or the lower wall of the corresponding light emitting plate, and the included angle between the light emitting plate and the ground is 0 to 20°.

[0085] In one specific embodiment, referring to the appendix Figure 10 , that is, β in the figure is greater than 0° and less than or equal to 20°. That is, the reflector tile is located above or below the lighting lamp beads of the lighting lamp and emits light towards the reflector tile. Since the lighting lamp beads do not occupy the size of the reflector tile in the front-rear direction of the vehicle, a reflector tile with a greater depth can be arranged in the limited accommodation space of the lighting lamp, so that the reflector tile has a stronger light condensing effect; conversely, for the same light condensing effect, the technical solution in which the lighting lamp beads do not occupy the front-rear direction size is also convenient for reducing the size of the accommodation space of the lighting lamp in the front-rear direction, so as to be convenient for reducing the total space of the front lamp assembly 3 and also convenient for the space layout of the overall vehicle.

[0086] In some alternative embodiments, the lighting beads are located on the upper wall of the light-emitting plate, and the lighting beads emit light toward the reflecting tile above them. The reflecting tile is located above the lighting beads, and the reflecting tile reflects the light to produce a focusing effect and shoots it forward of the vehicle.

[0087] In some other alternative embodiments, refer to Appendix Figure 8 and Appendix Figure 9 , the lighting beads are located on the lower wall of the light-emitting plate, and the lighting beads emit light toward the reflecting tile below them. The reflecting tile is located below the lighting beads, and the reflecting tile reflects the light to produce a focusing effect and shoots it forward of the vehicle. Further, since the light-emitting plate emits light downward, and the position of the front lamp assembly 3 is closer to the vehicle frame 1 in the up-down direction, that is, below the user's head, it is impossible for the user to observe the lighting beads when standing normally, and only the reflecting tile can be observed, and the overall appearance can be better.

[0088] In some alternative embodiments, in order to have a high lighting effect at a distance of 10 meters in front of the vehicle, the sum of the rated luminous powers of the lighting beads is 12W to 20W. More specifically, in some alternative embodiments, the rated luminous power of a single lighting bead is 0.5W to 5W. To meet the above requirements for illuminance, an appropriate number of lighting beads can be selected. In some alternative embodiments, the rated luminous power of a single lighting bead is 1 to 3W; more specifically, the rated luminous power of a single lighting bead in some embodiments is 2W. It should be additionally noted that the above description of the power does not mean that the rated powers of the individual lighting beads need to be the same, that is, as long as the sum of the rated luminous powers is within the above range, the combination of lighting beads with different powers should also be included in the protection scope of the above embodiments.

[0089] In some alternative embodiments, the light-emitting plate of the left lighting lamp 34 is not parallel to the light-emitting plate of the right lighting lamp 33. In some alternative embodiments, both light-emitting plates are inclined toward the middle position in the left-right direction, that is, the light-emitting plates are biased toward the middle position for lighting, so that the light has a tilting angle that slightly converges toward the middle. It is convenient to make the lights of the two lighting lamps coincide in front of the vehicle to achieve a stronger lighting effect.

[0090] In some alternative embodiments, the included angle between the light-emitting plate and the ground is 0 to 20°, and its small included angle does not cause it to occupy a large space in the up-down direction, and its inclined angle has the technical effects described above: the light is inclined toward the middle so that the lights of the left and right lighting lamps 33 can coincide in the front to enhance the lighting effect. In some alternative embodiments, the included angle between the light-emitting plate and the ground is 2° to 6°, and its smaller included angle better achieves the above technical effects, and the space it occupies in the up-down direction is smaller, which is more convenient for spatial layout.

[0091] In some alternative embodiments, the daytime running light 35 includes first lamp beads 352 arranged in an array, and the number of the first lamp beads 352 is 20 to 500. Preferably, the first lamp beads 352 are selected as LED lamp beads, and the LED lamp beads are arranged in a rectangular array, and the number of each single row is 18 to 30, and the number of rows is 2 to 5 rows.

[0092] In some alternative embodiments, the luminous power of the first lamp beads 352 is 0.01W to 0.5W. In some of these embodiments, when the luminous power of the first lamp beads 352 is 0.01W, the number of the first lamp beads 352 should be 200 to 500. When it works, a relatively prominent brightness can be generated, so as to achieve the effect of improving the vehicle's recognizability. In some other embodiments, the luminous power of the first lamp beads 352 is 0.2W, and the number of the first lamp beads 352 should be 20 to 50. A relatively prominent brightness can also be generated when it works, so as to achieve the effect of improving the vehicle's recognizability. In some other embodiments, the luminous power of the first lamp beads 352 is 0.5W, and the number of the first lamp beads 352 should be 10 to 30. A relatively prominent brightness can also be generated when it works, so as to achieve the effect of improving the vehicle's recognizability.

[0093] In some alternative embodiments, in order to enable the daytime running light 35 to have a relatively high brightness and effectively improve the vehicle's recognizability, the range of its rated luminous power should be 5W to 15W.

[0094] Further, the above power is the rated power of the first lamp beads 352. When the total rated power of the daytime running light 35 is relatively high and the lighting lamp is in the lit state, the vehicle can control the first lamp beads 352 of the daytime running light 35 to work at a reduced power to avoid unnecessary energy waste caused by excessive brightness.

[0095] Further, the main function of the daytime running light 35 is to improve the vehicle's recognizability, especially when used during the day with good ambient light. When the vehicle works at night, in order to produce a good lighting effect, the left and right lighting lamps 33 are turned on. Since the left and right lighting lamps 33 being lit will surely improve the vehicle's recognizability, generally, when the left and right lighting lamps 33 are turned on, the power of the daytime running light 35 is reduced, that is, the brightness of the daytime running light 35 is reduced, so as to reduce the heat generation of the daytime running light 35.

[0096] Further, in some alternative embodiments, the daytime running light 35 remains off when the left and right lighting lamps 33 of the vehicle are turned on, because at this time, there is no need for the daytime running light 35 to be lit to improve the vehicle's recognizability.

[0097] As described above, when the left and right lighting lamps 33 are lit, the daytime running lamp 35 does not need to operate at its rated power, that is, the actual luminous power when the left lighting lamp 34, the daytime running lamp 35, and the right lighting lamp 33 are lit simultaneously is not equal to the sum of their rated powers. In some alternative embodiments, when the left lighting lamp 34, the daytime running lamp 35, and the right lighting lamp 33 are lit simultaneously, the left and right lighting lamps 33 operate at their rated powers, and the daytime running lamp 35 operates at a reduced power, and the above actual luminous power is 14W to 30W.

[0098] In some alternative embodiments, the headlight assembly 3 further includes a headlight controller (not shown in the figure) for at least controlling the operation of the first lamp beads 352, and a vehicle controller (not shown in the figure) coupled to the headlight controller is disposed on the vehicle frame 1. The vehicle controller controls the operating states of the respective lamp beads of the headlight assembly 3 through the headlight controller.

[0099] In some alternative embodiments, the daytime running lamp 35 includes a middle lamp board, the first lamp beads 352 are arranged in an array on the middle lamp board, the middle lamp board is vertically placed so that the first lamp beads 352 face the front of the vehicle, and the headlight controller is disposed on the rear wall of the middle lamp board. Since the power of the daytime running lamp 35 is less than that of the lighting lamp, when all the lamp beads of the headlight assembly 3 are operating, the temperature of the middle lamp board will be lower than that of the light-emitting boards of the left and right lighting lamps 33. Especially when the left and right lighting lamps 33 and the daytime running lamp 35 are both turned on, the reduced brightness of the daytime running lamp 35 can make its heat generation smaller. And the headlight controller includes an MCU (microcontroller) that is relatively sensitive to temperature. Disposing it on the middle lamp board can reduce the probability of its failure caused by the high temperature of the lighting lamp board.

[0100] Further, in some alternative embodiments, the first lamp beads 352 of the daytime running lamp 35 can be controlled by the user or the vehicle controller to produce various lighting effects, such as flashing at a set frequency or alternately flashing of each first lamp bead 352 to achieve a running light effect, etc.

[0101] Further, in some alternative embodiments, when the left and right lighting lamps 33 of the vehicle are turned on, they remain lit, and the lighting lamp beads of the left and right lighting lamps 33 participate in the flashing pattern of the first lamp beads 352 of the daytime running lamp 35 to achieve a better visual lighting effect.

[0102] In some alternative embodiments, the daytime running lamp 35 further includes second lamp beads located in the left lighting lamp 34 and / or the right lighting lamp 33, that is, the daytime running lamp 35 further includes second lamp beads, and the physical position of the second lamp beads is in the space of the left lighting lamp 34 and / or the right lighting lamp 33. The second lamp beads are used to cooperate with the first lamp beads 352 to display various lighting effects. Specifically, the lighting effects that can be displayed include the first lamp beads 352 and the second lamp beads alternately flashing at a defined power, etc.

[0103] In some alternative embodiments, the distance between the reflector of the left lighting lamp 34 or the right lighting lamp 33 and the first lamp bead 352 closest thereto in the second direction is 10 mm to 100 mm. That is, in Figure 12 the size of L in the attachment is 10 mm to 100 mm. Looking at the headlight assembly 3 from the front of the headlight assembly 3, the visual effect is as follows: the light of the lighting lamp is emitted forward from the reflector; the light of the daytime running lamp 35 is emitted forward from the first lamp bead 352 of the daytime running lamp 35. The relatively close distance between the first lamp bead 352 and the reflector can make the light look more continuous, that is, show the effect of through-type lighting, and the visual effect is stronger. The above spacing of 10 mm to 100 mm can achieve the effect of continuous lighting. Further, in some alternative embodiments, the distance between the reflector and the first lamp bead 352 closest thereto in the second direction is 10 mm to 40 mm. The smaller spacing makes the visual continuity effect stronger and the through-type lighting effect better.

[0110] Further explanation is as follows: The above power system is detachably connected to the frame 1. The power system includes a plurality of battery units. The plurality of battery units can select at least one of the first specification battery pack and the second specification battery pack. The specification differences between the first specification battery pack and the second specification battery pack include, but are not limited to, differences in battery pack capacity, voltage, battery internal resistance, weight, size, energy density, cell type, charge information, battery health status information, etc.

[0111] In some alternative embodiments, the difference between the first specification battery pack and the second specification battery pack lies in the different battery pack capacities. The capacity of the first specification battery pack is greater than that of the second specification battery pack. The second specification battery pack is configured to provide power for handheld gardening tools. For example, the second specification battery pack can supply power to garden tools such as lawn trimmers, pruning shears, leaf blowers, and chain saws. In addition, the second specification battery pack can also supply power to torque output tools such as electric drills and jackhammers; supply power to sawing tools such as circular saws, jigsaws, and reciprocating saws, or supply power to grinding tools such as angle grinders and sanders.

[0112] In some alternative embodiments, the difference between the first specification battery pack and the second specification battery pack lies in the different types of battery cells selected. For example, the first specification battery pack and the second specification battery pack can select lithium iron phosphate battery cells and ternary lithium battery cells respectively. Multiple battery units in the power supply system can also select nickel-chromium battery cells, lead-acid battery cells, graphene battery cells, etc.

[0113] Multiple battery units of the power supply system select at least one of the first specification battery pack and the second specification battery pack. In this way, the multi-functional vehicle can be compatible with battery packs of different specifications, meeting the high-power work requirements and being able to adapt to handheld electric gardening tools at the same time, making the working mode of garden workers more flexible.

[0114] In one of the alternative embodiments, the power supply system further includes a battery compartment 6, a battery management system, etc. The battery compartment 6 is used to accommodate the battery pack, and the battery management system is used to manage the power supply of the battery pack to each component of the vehicle.

[0115] In one of the alternative embodiments, the battery compartment 6 and / or the battery management system are configured on the vehicle frame 1. The battery pack is detachably configured in the battery compartment 6 to achieve detachable and replaceable of the battery pack, and the removed battery pack can be used for the above-mentioned other electric gardening tools; and the design of the detachable battery pack enables the vehicle to quickly resume the working state by simply replacing the battery pack without waiting for a long charging time when the vehicle's power is low or exhausted.

[0116] In one of the alternative embodiments, the battery compartment 6 is detachably configured on the vehicle frame 1, and the battery pack is accommodated in the battery compartment 6, that is, the battery compartment 6 can be separated or combined with the vehicle frame 1 as a whole.

[0117] In another alternative embodiment, the gardening operation component is implemented as a cutter bar 4, and the gardening operation vehicle in this embodiment is a lawn mower; in addition, if the gardening operation component is a snow sweeping component, then the multi-functional gardening vehicle is a snow sweeper; that is, the gardening operation component, as the main functional component of the multi-functional gardening vehicle, can be changed according to the user's selection; at the same time, in some embodiments, the above-mentioned gardening operation component can also be a component that the user replaces according to actual needs. For example, if the cutter bar 4 for mowing is removed and replaced with a sweeping disc for sweeping the floor, then the lawn mower is changed to a floor sweeper. To sum up: No matter what functional component the gardening operation component is replaced with according to the user's needs, it should not be understood as breaking through the protection scope of this embodiment.

[0118] As mentioned above, the operation vehicle configured with a power system is a charging-type operation vehicle. Compared with the traditional fuel-powered operation vehicle, the charging-type operation vehicle has the advantages of all-weather zero emissions, zero fuel consumption, low noise, and simple maintenance (no gasoline, no engine oil, no air filter, no spark plug, no fuel storage, etc.). The power system of the charging-type operation vehicle uses an electric motor instead of a fuel engine, and the electric motors of the drive wheels can be controlled separately to achieve motion control of the whole vehicle, such as going straight, reversing, turning, and zero turning, reducing the structural complexity of the whole vehicle and making the control of the whole vehicle more flexible.

[0119] Similarly, the gardening vehicle configured with a power system is a charging-type gardening vehicle, and it also has the above-mentioned beneficial effects.

[0120] Refer to the appendix Figure 13 , the operation vehicle shown in the figure is configured with a steering lever. The user manipulates the steering lever to change the rotational speed of the drive wheels, thereby driving and controlling the vehicle; in other embodiments, the steering lever can also be changed to a steering wheel structure, that is, the control method of vehicle steering should not be understood as breaking through the protection scope of this embodiment.

[0121] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, commodity or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, commodity or device including the said element.

[0122] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0123] The present utility model is not limited to the above specific embodiments. Those of ordinary skill in the art can easily understand that there are many alternative solutions for the lawn mower and the control handle of the present utility model without departing from the principle and scope of the present utility model.
