For example, the terms such as "upper", "lower", "front", "rear", etc. indicating orientation or positional relationship are only based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present utility model.

[0056] Unless otherwise specified, the terms "set", "connected", and "connected" in the present utility model should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium.

[0057] 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 to perform garden operations.

[0058] The multi-functional garden vehicle in this embodiment further includes a headlight assembly 3 disposed on the vehicle frame 1, and the headlight assembly 3 is used to emit light in front of the vehicle. Further, the headlight assembly 3 includes a headlight base 31 and a headlight cover 32. The headlight base 31 and the headlight cover 32 are hermetically connected to form a sealed space, and a lighting lamp is disposed in the sealed space. The lighting lamp is used to illuminate in front of the vehicle.

[0059] Refer to the appendix Figure 1 In some embodiments of the present invention, the multi-functional garden vehicle further includes an outer lamp cover 2 disposed on the vehicle frame 1, and the headlight assembly 3 is disposed in the outer lamp cover 2, and the outer lamp cover 2 provides a certain protection effect for the headlight assembly 3.

[0060] The sealed space in this embodiment 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 protection characteristics; the IP protection level is composed of two digits. The first digit represents the level of dust protection and prevention of foreign objects from entering the electrical appliance. The second digit represents the degree of tightness of the electrical appliance against moisture and water ingress. 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 headlight assembly 3 can work normally in rainy weather without abnormal conditions such as water entering the lamp cover.

[0061] Furthermore, in another alternative embodiment, the above-mentioned sealed space meets the IPX6 waterproof level. Here, the second digit is 6, indicating that the sealed space meets the requirement of withstanding a powerful water column and can withstand a powerful 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 works in rainy weather.

[0062] Furthermore, in another alternative embodiment, the above-mentioned sealed space meets the IPX7 waterproof level. Here, the second digit is 7, indicating that the sealed space meets the requirement of withstanding temporary immersion and can withstand immersion underwater for a specified time and pressure. 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 works in rainy weather.

[0063] 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. 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.

[0064] Further, in some alternative embodiments, referring to Appendix Figure 4 , Appendix Figure 5 , Appendix Figure 6 , the first fastener is configured to be fixed to the protrusion 311 of the front lamp base 31, and the second fastener is configured to be fixed to the buckle 321 of the front lamp cover 32. The buckle 321 has a receiving space for accommodating the protrusion 311, and the protrusion 311 is accommodated in the receiving space when the front lamp cover 32 and the front lamp base 31 are fitted together.

[0065] 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 strip. It should be particularly noted that the above are only the processes by which the two can achieve sealing, and should not be limited to the understanding that the two are only connected by 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 the relative position of the two needs to be fixed by a connecting member such as a buckle 321 or a bolt, and then the gap between the two is caulked, that is, the gap is filled with sealant to keep the two in a sealed connection.

[0066] In some alternative embodiments, referring to Appendix Figure 2 , Appendix Figure 3 , Appendix Figure 4 , in the figure, the contour line of the contact surface between the front lamp base 31 and the front lamp cover 32 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 injecting hot melt sealant along the contact surface of the front lamp cover 32 and the front lamp base 31 is slightly reduced, thereby reducing production costs.

[0067] 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 strip can be selected for sealing.

[0068] In some alternative embodiments, the front lamp base 31 is provided with a waterproof and breathable device 313 for balancing the pressure inside and outside the sealed space, so as to prevent the sealing effect from being damaged due to a significant increase in pressure caused by the rise in temperature inside the sealed space. Refer to the appendix Figure 4 , the waterproof and breathable device 313 faces the rear of the vehicle, that is, the waterproof and breathable device 313 faces the above-mentioned outer lamp cover 2, reducing the possibility of external rainwater flowing to the waterproof and breathable device 313.

[0069] In some alternative embodiments, refer to the appendix Figure 5 , appendix Figure 5 is a partial enlarged schematic diagram of appendix Figure 4 . The waterproof and breathable device 313 includes a ventilation hole 3131 configured with a breathable membrane 3132. The breathable membrane 3132 has a waterproof and breathable effect, that is, air can pass through the breathable membrane 3132, but water molecules cannot pass through the breathable membrane 3132. Thus, it is possible to prevent external water vapor from entering the sealed space and affecting the lighting component, while also taking into account the ventilation effect. For the convenience of understanding, Figure 5 the breathable membrane 3132 at the ventilation hole 3131 in the figure is in a state of being separated from the ventilation hole 3131. In fact, the breathable membrane 3132 should be attached to the ventilation hole 3131.

[0070] Refer to the appendix Figure 5 , the figure shows that the front lamp base 31 is also provided with a wire 312 passing through it, and the vehicle body supplies power to the front lamp assembly 3 through the wire 312.

[0071] In some alternative embodiments, the porosity of the breathable membrane 3132 is 20% - 90%. In this embodiment, the heat generated by the lighting component is not too large, nor will it cause the air in the sealed space to expand too significantly. Therefore, the requirement for the porosity of the breathable membrane 3132 is not high. Generally, a breathable membrane 3132 with a porosity greater than 20% can meet the use 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 membrane 3132 with a porosity not higher than 90% can be selected.

[0072] The unilateral area of the breathable membrane 3132 at a single ventilation hole 3131 is 20mm 2 ~400mm 2; As described above, the heat generated by the lighting component will not be excessive and will not cause significant expansion of the air inside the enclosed space. However, the long-term operation of the lighting component will still cause a certain temperature difference between the inside and outside of the enclosed space. Therefore, when selecting the air-permeable membrane 3132 with a smaller porosity, a larger area of the air-permeable membrane 3132 is generally required. Conversely, when selecting the air-permeable membrane 3132 with a larger porosity, a slightly smaller area of the air-permeable membrane 3132 can generally meet the air permeability requirements. Generally speaking, for the air-permeable membrane 3132 with a porosity of 20% - 90%, the air-permeable membrane 3132 with a unilateral area of 20mm 2 ~400mm 2 can be selected in this embodiment. At the same time, the area of a single air-permeable membrane 3132 can be appropriately reduced by configuring multiple air-permeable membranes 3132 and air holes 3131.

[0073] It should be noted specifically that: generally, the air-permeable membrane 3132 is installed by gluing, that is, glue is applied to the edge of the air-permeable membrane 3132 to paste it on the edge of the air hole 3131. However, the part of the air-permeable membrane 3132 coated with glue cannot maintain the air permeability effect, that is, the effective air permeability area of the air-permeable membrane 3132 is smaller than its unilateral area.

[0074] In some alternative embodiments, referring to Attachment Figure 3 and Attachment Figure 4 , the illuminating lamp includes a left illuminating lamp 34 and a right illuminating lamp 33, and the air holes 3131 include a left air hole 3131 and a right air hole 3131 respectively located behind the left illuminating lamp 34 and the right illuminating lamp 33. In some other alternative embodiments, the illuminating lamp further includes a daytime running lamp 35 disposed inside the enclosed space and between the left illuminating lamp 34 and the right illuminating lamp 33, and the air holes 3131 further include a middle air hole 3131 located behind the daytime running lamp 35.

[0075] In some alternative embodiments, the left illuminating lamp 34 and the right illuminating lamp 33 include illuminating lamp beads that emit light when powered on, and the daytime running lamp 35 includes a first lamp bead 352 that emits light when powered on; the illuminating lamp beads are mainly used to produce an illuminating effect in front of the vehicle. When the ambient light is poor, the left illuminating lamp 34 and the right illuminating lamp 33 are turned on so that the user can better observe the ground in front of the vehicle to perform garden operations better. 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 operation vehicle that may have safety risks here and will not continue to approach, thereby improving the operation safety performance of the vehicle.

[0076] In some alternative embodiments, the power of the first lamp bead 352 is less than the power of the illuminating lamp beads, and the power here is the rated power of the corresponding lamp beads.

[0077] In some alternative embodiments, the illuminating lamp of the headlamp assembly 3 includes a light condensing portion and illuminating lamp beads that emit light when powered on. The light emitted by the illuminating lamp beads is affected by the light condensing effect of the light condensing portion, so that 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 some other alternative embodiments, the light intensity generated by the lighting assembly at a distance of 10 meters in front of the multi-functional garden vehicle is 20 lux to 40 lux. In some other alternative embodiments, the light intensity generated by the lighting assembly at a distance of 10 meters in front of the multi-functional garden vehicle is 25 lux to 35 lux. It is used to meet the lighting within 10 meters in front, so as to facilitate the user to timely obtain the ground conditions within 10 meters in front of the vehicle. More specifically, in one embodiment, the integrated headlamp assembly generates a light intensity of 30 lux at a distance of 10 meters in front of the multi-functional operation vehicle.

[0078] Refer to the attached Figure 11 , the figure shows a schematic diagram of the headlamp assembly 3 emitting light towards the front of the vehicle. The light rays of the left illuminating lamp 34 and the right illuminating lamp 33 in the figure coincide at a distance X in the front, so that the left illuminating lamp 34 and the right illuminating lamp 33 jointly achieve sufficient illumination of the coincident position. In some specific embodiments, the above X is 10 meters, and the headlamp generates a light intensity of 30 lux at the light coincidence position at this 10-meter distance.

[0079] In some alternative embodiments, the light condensing portion is configured as a lens and / or a reflector tile, and the illuminating lamp beads emit light towards the light condensing portion. In some alternative embodiments, the light condensing portion selects a convex lens facing the front of the vehicle, which has the effect of concentrating the divergently irradiated light to only irradiate forward. In some other alternative embodiments, the light condensing portion selects a reflector tile. A coating is arranged on the side of the reflector tile close to the illuminating 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 rays emitted by the illuminating lamp beads are reflected by the concave surface to form light rays that are nearly parallel and irradiate forward, so as to be able to produce a stronger lighting effect on a farther distance in front of the vehicle.

[0080] In some alternative embodiments, in order to simplify the assembly, the illuminating lamp includes a light emitting plate, and the illuminating lamp beads are arranged on the light emitting plate. Specifically, refer to the attached Figure 8 , the right illuminating lamp 33 includes a right light emitting plate 331 and a right reflector tile 332 as the light condensing portion, and the left illuminating lamp 34 includes a left light emitting plate 341 and a left reflector tile 342 as the light condensing portion.

[0081] In some alternative embodiments, refer to the attached Figure 9, the left light-emitting plate 341 is not parallel to the right light-emitting plate 331. In some 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 illumination, so that the light has a tilt angle towards the middle, facilitating the overlapping of the lights of the two lighting lamps in front of the vehicle to achieve a stronger lighting effect.

[0082] 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°.

[0083] In one specific embodiment, referring to the attached Figure 10 , that is, β in the figure is greater than 0° and less than or equal to 20°. That is, the reflective tile is located above or below the lighting lamp beads and emits light towards the reflective tile. Since the lighting lamp beads do not occupy the size of the reflective tile in the front-rear direction of the vehicle, a reflective tile with a greater depth can be configured within the limited accommodation space for the lighting lamps, thereby enabling the reflective tile to have a stronger light-gathering effect; conversely, for the same light-gathering effect, the technical solution where the lighting lamp beads do not occupy the front-rear dimension also facilitates reducing the size of the accommodation space for the lighting lamps in the front-rear direction, thus facilitating reducing the total space of the front lamp assembly 3 and also facilitating the spatial layout of the entire vehicle.

[0084] In some alternative embodiments, the lighting lamp beads are located on the upper wall of the light-emitting plate, and the lighting lamp beads emit light towards the reflective tile above it. The reflective tile is located above the lighting lamp beads, and the reflective tile reflects and gathers the light and shoots it towards the front of the vehicle.

[0085] In some other alternative embodiments, referring to the attached Figure 8 and the attached Figure 9 , the lighting lamp beads are located on the lower wall of the light-emitting plate, and the lighting lamp beads emit light towards the reflective tile below it. The reflective tile is located below the lighting lamp beads, and the reflective tile reflects and gathers the light and shoots it towards the front 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, lower than the user's head, it is impossible for the user to observe the lighting lamp beads when standing normally, and only the reflective tile can be observed, and the overall appearance can be better.

[0086] In some alternative embodiments, to achieve 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, in some of the embodiments, the rated luminous power of a single lighting bead is 2W. It should be additionally noted that the above description of 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 falls within the above range, combinations of lighting beads with different powers should also be included in the scope of protection of the above embodiments.

[0087] 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 towards the middle position in the left-right direction, that is, the light-emitting plates are biased towards the middle position for illumination, so that the light has a slight inclination angle towards the middle. This facilitates the overlapping of the lights of the two lighting lamps in front of the vehicle to achieve a stronger lighting effect.

[0088] In some alternative embodiments, the angle between the light-emitting plate and the ground is 0 to 20°. This relatively small angle does not cause it to occupy a large amount of space in the up-down direction, and its inclined angle has the technical effect described above: the light is inclined towards the middle so that the lights of the left and right lighting lamps 33 can overlap in the front to enhance the lighting effect. In some alternative embodiments, the angle between the light-emitting plate and the ground is 2° to 6°. This smaller angle better achieves the above technical effect, and it occupies less space in the up-down direction, making it more convenient for spatial arrangement.

[0089] In some alternative embodiments, the daytime running lamp 35 includes a first row of beads 352 arranged in an array, and the number of the first row of beads 352 is 20 to 500. Preferably, the first row of beads 352 is selected as LED beads, and the individual LED beads are arranged in a rectangular array, and the number of beads in a single row is 18 to 30, and the number of rows is 2 to 5.

[0090] In some alternative embodiments, the luminous power of the first lamp bead 352 is 0.01W - 0.5W. In some of these embodiments, if the luminous power of the first lamp bead 352 is 0.01W, the number of the first lamp beads 352 should be between 200 and 500. When it works, a relatively prominent brightness can be generated, thus achieving the effect of improving the vehicle's recognizability. In some other embodiments, if the luminous power of the first lamp bead 352 is 0.2W, the number of the first lamp beads 352 should be between 20 and 50, and a relatively prominent brightness can also be generated when it works, thus achieving the effect of improving the vehicle's recognizability. In some other embodiments, if the luminous power of the first lamp bead 352 is 0.5W, the number of the first lamp beads 352 should be between 10 and 30, and a relatively prominent brightness can also be generated when it works, thus achieving the effect of improving the vehicle's recognizability.

[0091] In some alternative embodiments, in order to make the daytime running lamp 35 have a relatively high brightness and effectively improve the vehicle's recognizability, the range of its rated luminous power should be 5W - 15W.

[0092] Furthermore, the above power is the rated power of the first lamp bead 352. When the total rated power of the daytime running lamp 35 is relatively high and the lighting lamp is in the lit state, the vehicle can control the first lamp bead 352 of the daytime running lamp 35 to work at a reduced power to avoid unnecessary energy waste caused by its too high brightness.

[0093] Furthermore, the main function of the daytime running lamp 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 the power of the daytime running lamp 35 is reduced when the left and right lighting lamps 33 are turned on, that is, the brightness of the daytime running lamp 35 is reduced, thereby reducing the heat generation of the daytime running lamp 35.

[0094] Furthermore, in some alternative embodiments, the daytime running lamp 35 remains in the off state when the left and right lighting lamps 33 of the vehicle are turned on, because there is no need for the daytime running lamp 35 to be lit to improve the vehicle's recognizability at this time.

[0095] As described above, when the left and right lighting lamps 33 are lit, the daytime running lamp 35 does not need to work 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 work at their rated powers, and the daytime running lamp 35 works at a reduced power. The above actual luminous power is 14W - 30W.

[0096] 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 light beads 352, and a vehicle controller (not shown in the figure) coupled to the headlight controller is configured on the vehicle frame 1. The vehicle controller controls the operating states of the respective light beads of the headlight assembly 3 through the headlight controller.

[0097] In some alternative embodiments, as described above: The daytime running light 35 includes a middle light board 35, and the first light beads 352 are arranged in an array on the middle light board 35. The middle light board 35 is vertically placed so that the first light beads 352 face the front of the vehicle, and the headlight controller is configured on the rear wall of the middle light board 35. Since the power of the daytime running light 35 is less than that of the illumination light, when all the light beads of the headlight assembly 3 are operating, the temperature of the middle light board 35 will be lower than the light-emitting boards of the left and right illumination lights 33. Especially when the left and right illumination lights 33 and the daytime running light 35 are both turned on, the reduced brightness of the daytime running light 35 can make its heat generation smaller. And the headlight controller includes an MCU (microcontroller) that is relatively sensitive to temperature. Configuring it on the middle light board 35 can reduce the probability of its failure caused by the high temperature of the illumination light board.

[0098] Further, in some alternative embodiments, the first light beads 352 of the daytime running light 35 can be controlled by the user or the vehicle controller to produce various lighting effects, such as flashing at a set frequency or the first light beads 352 flashing alternately to achieve a running light effect, etc.

[0099] Further, in some alternative embodiments, it remains lit when the left and right illumination lights 33 of the vehicle are turned on, and the illumination light beads of the left and right illumination lights 33 participate in the flashing pattern of the first light beads 352 of the daytime running light 35 to achieve a better visual lighting effect.

[0100] In some alternative embodiments, the daytime running light 35 further includes a second light bead located within the left illumination light 34 and / or the right illumination light 33, that is, the daytime running light 35 further includes a second light bead, and the physical position of this second light bead is within the space of the left illumination light 34 and / or the right illumination light 33. The second light bead is used to cooperate with the first light beads 352 to display various lighting effects. Specifically, the lighting effects that can be displayed include the first light beads 352 and the second light beads flashing alternately at a defined power, etc.

[0101] In some alternative embodiments, the distance between the reflector tile of the left illumination light 34 or the right illumination light 33 and the nearest first light bead 352 in the second direction is 10 mm to 100 mm. That is Figure 12The size of L 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 illumination lamp is emitted forward from the reflector; the light of the DRL 35 is emitted forward from the first lamp bead 352 of the DRL 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-mentioned distance of 10 mm to 100 mm can achieve the effect of continuous lighting. Further, in some optional embodiments, the distance between the reflector and the nearest first lamp bead 352 in the second direction is 10 mm to 40 mm. Its smaller distance makes the visual continuity effect stronger and the through-type lighting effect better.

[0108] Further explanation: 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 a first specification battery pack and a 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.

[0109] In some alternative embodiments, the difference between the first specification battery pack and the second specification battery pack lies in different battery pack capacities. The capacity of the first specification battery pack is greater than the capacity of the second specification battery pack. The second specification battery pack is configured to provide power for handheld garden tools. For example, the second specification battery pack can supply power to garden tools such as a grass trimmer, a pruning shear, a blower, and a chain saw. In addition, the second specification battery pack can also supply power to torque output tools such as an electric drill and a hammer drill; supply power to sawing tools such as a circular saw, a jigsaw, and a reciprocating saw, or supply power to grinding tools such as an angle grinder and a sander.

[0110] 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 may respectively select lithium iron phosphate battery cells and ternary lithium battery cells. Multiple battery units in the power system may also select nickel-chromium battery cells, lead-acid battery cells, graphene battery cells, etc.

[0111] Multiple battery units of the power system select at least one of the first specification battery pack and the second specification battery pack. This way enables the multi-functional vehicle to be compatible with different specifications of battery packs, meeting the high-power working requirements and being able to adapt to handheld electric gardening tools at the same time, making the working mode of gardening staff more flexible.

[0112] In one of the alternative embodiments, the power 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.

[0113] In one of the alternative embodiments, the battery compartment 6 and / or the battery management system is configured on the vehicle frame 1, and the battery pack is detachably configured in the battery compartment 6, which is used to realize the detachable and replaceable of the battery pack, and the removed battery pack can be used for the above other electric gardening tools; and the design of the detachable battery pack enables the vehicle to quickly return to the working state by simply replacing the battery pack without waiting for a long charging time when the battery power of the vehicle is low or exhausted.

[0114] 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.

[0115] In another alternative embodiment, the gardening operation component is implemented as a cutting table 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 choice; at the same time, in some embodiments, the above gardening operation component can also be a component replaced by the user according to actual needs, such as removing the cutting table 4 for mowing and replacing it with a sweeping disc for sweeping, then changing the lawn mower to a sweeper. In summary: replacing the gardening operation component with any functional component according to the user's needs should not be understood as breaking through the protection scope of this embodiment.

[0116] As described above, the work vehicle configured with a power supply system is a charging-type work vehicle. Compared with traditional fuel-powered work vehicles, the charging-type work 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 work 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 straight running, reversing, turning, and zero turning, reducing the structural complexity of the whole vehicle and making the control of the whole vehicle more flexible.

[0117] Similarly, the gardening vehicle configured with a power supply system is a charging-type gardening vehicle and also has the above beneficial effects.

[0118] Refer to the attached Figure 13 , in the figure, the work vehicle shown is configured with a steering lever. The user manipulates the steering lever to change the rotational speed of the drive wheels, thereby controlling the driving of 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.

[0119] 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 explicitly listed, or elements inherent to such process, method, commodity or device.
