Description

Power supply system and electric vehicle Technical Field

[0001] The present application relates to the field of electric vehicles, and more specifically, to a power supply system and an electric vehicle. Background Art

[0002] Electric vehicles are widely used in the field of garden tools. They typically consist of a power unit that propels them and functional components for performing specific tasks. Depending on the specific product design, the power unit and functional components can use the same or different power sources. The tasks that functional components can perform typically include mowing, fertilizing, and snow removal.

[0003] With the increasing adoption of environmental protection requirements, the widespread use of green energy, and advancements in lithium battery technology, more and more electric vehicles are adopting lithium batteries as their energy source. These vehicles are typically used outdoors in harsh environments, such as riding lawn mowers and sit-on lawn mowers. These vehicles, for example, are used in the wild, where the terrain is dense and complex, often with dense vegetation. This can lead to unexpected situations, such as the vehicle running out of power and being unable to return; the vehicle losing power in the wild, forcing the user to wait; and the need for additional power to operate other tools carried in the wild.

[0004] Existing electric vehicles, especially riding lawn mowing equipment, are difficult to solve the above problems.

[0084] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0085] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0086] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0087] The meaning of "and / or" in this application means that both situations where each exists alone or both exist at the same time are included.

[0088] The meaning of "inside" and "outside" in this application refers to the direction from the signal line to the inside of the working area relative to the signal line itself, that is, the direction from the signal line to the inside of the working area is inside, and the opposite is outside; it is not a specific limitation on the device mechanism of this application.

[0089] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0090] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0091] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0092] Furthermore, unless otherwise specified, the technical solutions of the following embodiments of the present application can be combined with each other.

[0093] Example 1

[0094] As shown in Figure 1, a power supply system and an electric vehicle are shown. The electric vehicle may be, but is not limited to, a sit-on lawn mower. This embodiment uses a sit-on lawn mower as an example for further explanation. In this embodiment, the sit-on lawn mower includes a body 100 and a power supply, drive components, steering components, control components, functional components, input components, and output components, all of which are mounted on the body 100.

[0095] In this embodiment, it should be noted that the power source can be a battery, for example, a lithium battery, the drive component can be an electric motor, and the functional component can be a mowing disc driven by the motor. Both the input component and the output component 200 are mounted on the exterior of the vehicle body. The input component is configured to connect to an external energy source and charge the lithium battery of the sit-on lawn mower. The output component 200 is provided with a socket configured to electrically connect to an external device, thereby providing power to the external device. For example, the external device can be a tablet, a mobile phone, or a power bank.

[0096] As shown in FIG2 , the number of output components 200 can be one or more. For example, in this embodiment, there are three output components 200, which can be arranged at different locations on the exterior of the sit-on lawn mower. Specifically, the three output components 200 are arranged at the rear, side, and top of the rear seat of the mower. Output component 200b is located at the rear of the mower, output component 200c is located at the side of the mower, and output component 200a is located at the top of the rear seat of the mower. It should be understood that locations not shown in FIG2 , such as under the seat, on the pedal surface, or on the armrests next to the seat, could also be used to arrange output components 200. This embodiment uses output component 200b located at the rear of the vehicle body 100 as an example for further explanation.

[0097] As shown in Figure 3, it is a schematic diagram of the power supply system and the control system of the electric vehicle. The battery of the lawn mower is electrically connected to the AC input, AC output, DC input, DC output, other inputs, other outputs and functional modules at the same time. It should be noted that other inputs may include photovoltaic panel input and other inputs, other outputs may include outputs of wireless charging devices, and functional modules may include electronic components on the lawn mower that require electrical energy, such as drive modules and cutting modules.

[0098] The framework diagram shown in Figure 4 illustrates the power system within an electric vehicle. The power system within a lawn mower includes a battery, an inverter, and a control module. The battery is electrically connected to the inverter, which is electrically connected to an AC input. The AC input can be a socket configured to connect to an AC charger. The control module is electrically connected to the inverter and is also electrically connected to both the AC output and the DC output to output electrical energy. The battery itself can be directly connected to the DC output, with necessary electronic components interposed to adjust output parameters, though this is not described in detail in this embodiment. In actual implementation, the battery is electrically connected to the control module, which can obtain battery parameters, display battery usage status, and control the battery and other functional units. Both the battery and the control module can be electrically connected to the DC input, which charges the battery via a DC charger. Other components within the lawn mower that require electrical energy can obtain this energy by directly connecting to the battery or to the control module. These other components include, but are not limited to, the drive motor, light source, audio equipment, and speakers.

[0099] In this embodiment, optionally, the photovoltaic panel installed on the vehicle body can charge the battery. The inverter part inside the lawn mower is connected to the MPPT, and the MPPT is connected to the input port set on the lawn mower. After the external photovoltaic panel is connected to the input port, the battery of the lawn mower can be charged. In this way, solar energy is reasonably utilized, energy utilization efficiency is improved, and operating costs are reduced.

[0100] In this embodiment, the output component 200 is optionally disposed at the rear of the vehicle body 100. As shown in Figure 5, the output component 200 includes an output panel 201 and a cover disposed outside the output panel 201. The cover can cover the output panel 201 to provide protection. In actual use, the cover can be a single independent cover or a combination of multiple covers. In this embodiment, the output panel 201 is equipped with two covers, namely an upper cover 202 and a lower cover 203. The two covers are arranged in an upper and lower position relative to the rear of the vehicle, with the upper cover 202 located above the lower cover 203. The two covers can be opened independently in opposite directions. For example, the side of the upper cover 202 away from the lower cover 203 is rotatably connected to the rear of the vehicle, and the side of the lower cover 203 away from the upper cover is rotatably connected to the rear of the vehicle. When the upper cover 202 and the lower cover 203 are both in the position of closing the output panel 201, the side of the upper cover 202 close to the lower cover 203 is docked with the side of the lower cover 203 close to the upper cover 202, and the two cooperate to protect the output panel 201.

[0101] Optionally, in order to facilitate the operation of the upper cover 202 and the lower cover 203, a groove can be set in the middle position of the side of the upper cover 202 close to the lower cover 203, and a groove can also be set in the middle position of the side of the lower cover 203 close to the upper cover 202. The operator's fingers can hold the groove, which is not easy to slip during the process of opening and closing the upper cover 202 or the lower cover 203, and the operation is convenient and quick.

[0102] As shown in Figure 6, it shows a state where only the upper cover 202 is open. In this state, the upper area of ​​the output panel 201 is exposed. This area is the AC output area 204. AC output sockets can be arranged in this area. The AC output sockets can include 110V output sockets, 120V output sockets, and 220V output sockets, etc.

[0103] As shown in Figures 7 and 8, it shows the state where only the lower cover 203 is open. In this state, the lower area of ​​the output panel 201 is exposed. This area is the DC output area 205, and a DC output socket can be arranged in this area. The DC output socket can include a USB socket, a Type-C socket, a DC5521 socket and a cigarette lighter socket 208, etc.

[0104] As shown in FIG9 , the output panel 201 is further provided with a display element 206 and a switch button 207. The display element 206 is configured to display the battery usage status, and the switch button 207 is configured to control the opening and closing of the output component 200. Specifically, the switch button 207 can be configured to control the opening and closing of the display element 206 and / or the output socket. It should be understood that the switch button 207 can be a touch key, a button, or a knob.

[0105] As shown in Figure 10, the multiple sockets on the output panel 201 are described. The AC output area 204 of the output panel 201 is equipped with a 120V socket 209 and a 125V socket 210. The 125V socket 210 can output 30A current and is configured to power an RV. The DC output area 205 of the output panel 201 is equipped with a Type-A socket 211, a Type-C socket 212, a DC5521 socket, and a cigarette lighter socket 208.

[0106] It should be noted that the display element 206 and the switch button 207 are disposed on the output panel 201 in an area corresponding to the area covered by the lower cover 203 .

[0107] In this embodiment, the output panel 201 optionally includes a recessed groove, with the AC power output jack, DC power output jack, display element 206, and switch button 207 positioned on the bottom wall of the recessed groove. This reduces the length of the electric vehicle when the upper and lower covers 202 and 203 are closed. Furthermore, the AC power output jack, DC power output jack, display element 206, and switch button 207 are concealed within the recessed groove, making them less susceptible to collision and damage.

[0108] As shown in Figures 11 and 12, the specific display content of display element 206 is shown. The display area of ​​display element 206 includes a battery status display area 2061, an other status display area 2062, and an output status display area 2063. The battery status display area 2061 is located in the center of the display area and is configured to display parameters such as battery charge and usable time. The battery status display area 2061 can also display input power, output power, and whether the input power and output power are overloaded. The other status display area 2062 and the output status display area 2063 are located above and below the battery status display area 2061, respectively. The output status display area 2063 displays the operating status of the output socket, including whether it is faulty and in use. Each type of socket can be indicated by a separate icon. The other status display area 2062 is configured to display additional information in addition to the information displayed in the battery status display area 2061 and the output status display area 2063. Specifically, it can include information such as battery temperature, ambient temperature, radiator status, audio device volume, charging time, Bluetooth connection status, and wireless connection status.

[0109] As shown in Figure 13, the specific structure of the input component on the vehicle body 100 is shown. The input component is arranged on the outer shell of the vehicle body 100 and includes a cover 301. The cover 301 is flexibly connected to the outer shell so that it can be switched between an open state and a closed state. For example, the cover 301 can be arranged to be rotatably connected to the shell. When the cover is rotated open, the AC input socket and the DC input socket are exposed. Similarly, when the cover is rotated closed, the AC input socket and the DC input socket are blocked. In this embodiment, optionally, the number of AC input sockets is set to one, and the number of DC input sockets is set to multiple. The multiple DC input sockets are arranged around the AC input socket, that is, the multiple DC inputs are arranged around the AC input socket and spaced apart. Among them, the DC input socket includes a socket connected to the photovoltaic panel.

[0110] As shown in Figure 14, during use, the photovoltaic panel can be connected to the vehicle body 100 through the DC input socket, and the photovoltaic panel can be used to charge the battery. The photovoltaic panel can be placed in the storage space of the vehicle body 100 or fixedly set on the shell of the vehicle body 100 exposed to the outside, such as in the space above the rear of the vehicle body 100. When the photovoltaic panel is set to a storage form, a foldable photovoltaic panel can also be used. When the vehicle body 100 is out of power in the wild, the photovoltaic panel can be used to charge the battery of the vehicle body 100, so that the user can escape.

[0111] Example 2

[0112] This embodiment also provides a power supply system and an electric vehicle. This embodiment further improves upon the technical solutions of the first embodiment. To avoid repetition, the technical solutions already disclosed in the first embodiment will not be detailed in this embodiment. In this embodiment, an upper cover 202 and a lower cover 203 are also provided on the exterior of the output panel 201. As shown in Figures 15 and 16, a wireless charging element 213 is also provided on the interior of the lower cover 203, configured to wirelessly charge an electronic device. A light source component 214 is provided on the interior of the upper cover 202, configured to provide illumination. The light source component 214 may be a light-emitting element such as an LED lamp. Both the upper cover 202 and the lower cover 203 are hollow in design, with the wireless charging element 213 and the light source component 214 disposed within the internal cavities of the upper and lower covers 202 and 203, respectively. Wiring can be routed through hinges at the connection between the upper cover 202 and the output panel 201, and through hinges at the connection between the lower cover 203 and the output panel 201. This type of hinge connection and wiring arrangement is common in electronic devices and will not be described in detail in this embodiment. The lower cover 203 may also include a pull rod or other components at the connection point to enhance stability after opening. That is, when the lower cover 203 is opened, it can be at a zero-degree angle to the horizontal plane, that is, the lower cover 203 is essentially parallel to the horizontal plane. At this time, the inner surface of the lower cover 203 faces upward and is arranged horizontally, allowing electronic devices such as mobile phones to be placed on the inner surface of the lower cover 203 for charging. The electronic device is placed horizontally, which is stable with the lower cover 203, making it difficult to fall, and safe and reliable. It should be understood that a positioning groove can also be provided on the inner surface of the lower cover 203, and the wireless charging component 213 is placed in the positioning groove. The charging electronic device can also be placed in the positioning groove and positioned by the positioning groove to prevent it from sliding off the inner surface of the lower cover 203. It should be understood that in other embodiments, a limiting post can also be provided on the inner surface of the lower cover 203. The electronic device to be charged is placed on the inner surface and contacts the limiting post. The limiting post can serve to limit the position of the electronic device and prevent it from sliding. The number of limiting posts can be multiple and arranged in a ring, with the electronic device to be charged positioned within the area enclosed by the multiple limiting posts. Optionally, the limiting posts can be configured as elastic posts, which form elastic contact with the electronic device to be charged, resulting in minimal wear and scratching, making the device safe and reliable to use. Furthermore, because the limiting posts are elastic, they can deform to accommodate the clamping and positioning of electronic devices of varying sizes, providing a wide range of applications and excellent limiting effects.

[0113] In this embodiment, the opening and closing angles of the upper cover 202 and the lower cover 203 are optionally limited. The opening and closing angle of the lower cover 203 does not exceed 180 degrees. More preferably, when the lower cover 203 is in its maximum opening and closing state, the inner surface of the lower cover 203 remains horizontal with the forward direction of the vehicle body 100. The maximum opening and closing angle of the upper cover 202 does not exceed 270 degrees. More preferably, the opening and closing angle of the upper cover 202 does not exceed 180 degrees, or the upper cover 202 can be fixed in place when opened and closed to the vertical position by a retaining structure. Possible retaining structures include positioning buckles on the hinge connecting the upper cover 202 to the vehicle body 100, or additional brackets that can be used to maintain the upper cover 202 in place when it is rotated upward to the vertical position.

[0114] It should be understood that when the lower cover 203 is rotated to the maximum opening and closing state, it can also be positioned by positioning buckles or brackets to improve stability.

[0115] In this embodiment, both the upper cover 202 and the lower cover 203 are optionally rotatably connected to the vehicle frame 101 using damping hinges. This design allows for locking at any angle during rotation. Furthermore, in this embodiment, the output panel 201 is vertically positioned, with the upper cover 202 having a maximum opening and closing angle of 180 degrees and the lower cover 203 having a maximum opening and closing angle of 90 degrees. When the upper cover 202 is closed, it is vertically positioned, and when the lower cover 203 is closed, it is vertically positioned.

[0116] In this embodiment, optionally, separate opening buttons / switches may be provided on the inner sides of the upper cover 202 and the lower cover 203 for the light source component 214 and the wireless charging element 213. In another embodiment, a sensor may be provided inside the upper cover 202 and / or the lower cover 203, the sensor being configured to detect the opening status of the upper cover 202 and / or the lower cover 203. When the upper cover 202 and / or the lower cover 203 are opened, the light source component 214 on the upper cover 202 and / or the wireless charging element 213 on the lower cover 203 may be automatically turned on. The specific sensor may be an angle sensor or a Hall sensor. When an angle sensor is used, the tilt angle of the upper cover 202 and / or the lower cover 203 may be detected to determine the opening status of the upper cover 202 and / or the lower cover 203. When using a Hall sensor, a Hall sensor and a magnetic material can be set on the upper cover 202 and the output panel 201 respectively. By detecting the parameters of the Hall sensor, it can be determined whether the upper cover 202 is separated from the output panel 201, thereby determining the open state of the upper cover 202. The lower cover 203 can be implemented in the same way.

[0117] That is, in some embodiments, a sensor can be provided on the upper cover 202, configured to be linked to the activation switch of the light source component 214. That is, when the sensor on the upper cover 202 detects that the upper cover 202 is opened to a preset angle, the light source component 214 is directly turned on. Similarly, in some embodiments, a sensor can be provided on the lower cover 203, configured to be linked to the activation switch of the wireless charging component 213. That is, when the sensor on the lower cover 203 detects that the lower cover 203 is opened to a preset angle, the wireless charging component 213 is directly turned on. Optionally, in some embodiments, sensors can be provided on both the upper cover 202 and the lower cover 203 to respectively detect the opening angles of the upper cover 202 and the lower cover 203, thereby controlling the electronic components.

[0118] As shown in Figure 16, a locking component can also be set between the cover body and the output panel 201 to position the cover body. In this embodiment, a first adsorption component 215 and a second adsorption component 216 are respectively provided on the upper cover 202 and the output panel 201. The two are magnetically adsorbed. When the upper cover 202 is closed, it is adsorbed and fixed by the first adsorption component 215 and the second adsorption component 216. It should be noted that a magnetic adsorption structure can be used between the lower cover 203 and the output panel 201 to achieve locking of the lower cover 203 when it is in the closed position.

[0119] It should be understood that both the first adsorption member 215 and the second adsorption member 216 can be configured as strong magnets. Furthermore, the number of the first adsorption member 215 and the second adsorption member 216 can be multiple, thereby improving the adsorption effect. For example, in this embodiment, the number of the first adsorption member 215 and the second adsorption member 216 are both two, and the first adsorption member 215 is located on the side of the upper cover 202 close to the lower cover 203.

[0120] As shown in FIG17 , the lower cover 203 is further provided with a perspective element 217 and an auxiliary switch 218 . The perspective element 217 is made of a transparent material. When the lower cover 203 is closed, the information displayed on the display element 206 can be viewed through the perspective element 217 . Simultaneously, the auxiliary switch 218 is configured to control the opening and closing of the output component 200 . Specifically, the auxiliary switch 218 can be configured to control the opening and closing of the display element 206 and / or the output socket. In actual operation, the auxiliary switch 218 can be an independent electronic switch. In another embodiment, the auxiliary switch 218 can also be a component that can slide relative to the lower cover 203 . When the lower cover 203 is closed, the auxiliary switch 218 is pressed, and the auxiliary switch 218 slides relative to the lower cover 203 until the end contacts the switch button 207 on the output panel 201 , thereby controlling the switch button 207 .

[0121] For ease of use, a voice module can also be provided in the lawn mower. The voice module is configured to receive external sound information. The voice module can also process the received external sound information and generate control instructions after processing to control the display element 206 and control the opening and closing of the AC output interface and the DC output interface.

[0122] Example 3

[0123] This embodiment also provides a power supply system and an electric vehicle. This embodiment is a further improvement based on the technical solutions of the first and second embodiments. To avoid redundant description, the technical solutions already disclosed in the first and second embodiments will not be described in detail in this embodiment. In this embodiment, the connection structure between the upper cover and the lower cover and the output panel is mainly described. As shown in Figures 18 and 19, the output panel 201 at the rear of the vehicle body 100 is movably connected to the upper cover 202 and the lower cover 203. As shown in Figure 20, it shows an exploded schematic diagram of the connection structure between the upper cover 202 and the output panel 201 and the lower cover 203 and the output panel 201. The upper cover 202 and the lower cover 203 are both movably connected to the output panel 201 through the covering member 219, the rotating member 220 and the fixing member 221. In other words, the connection structure between the upper cover 202 and the lower cover 203 and the output panel 201 is the same.

[0124] As shown in Figure 21, the output panel 201 is provided with mounting windows 222 and mounting seats 223 at positions corresponding to the upper cover 202 and the lower cover 203. That is, the upper side of the output panel 201 is provided with mounting windows 222 and mounting seats 223 corresponding to the mounting position of the upper cover 202, and the lower side of the output panel 201 is provided with mounting windows 222 and mounting seats 223 corresponding to the mounting position of the lower cover 203. There are two mounting seats 223, one at each end of the corresponding mounting window 222. The mounting window 222 is a strip-shaped slot that runs through the output panel 201.

[0125] As shown in Figures 22 and 23, Figure 22 shows an exploded view of the connection structure of the lower cover 203, and Figure 23 shows an exploded view of the connection structure of the upper cover 202. The connection structure for mounting the upper cover 202 and the lower cover 203 is configured to be identical. To avoid redundant description, this embodiment uses one connection structure as an example. The connection structure includes a covering member 219, a rotating member 220, and a fixed member 221. As shown in Figures 24 and 25, the mounting base 223 includes a rotating mounting base 2231 and a fixed mounting base 2232, wherein the rotating mounting base 2231 is located adjacent to the mounting window 222.

[0126] As shown in FIG. 26 , the specific structure of the fixing member 221 is shown. The fixing member 221 is provided with a fixing seat 2211 which is configured to be connected to the fixing mounting seat 2232 .

[0127] As shown in Figure 27, the specific structure of the rotating member 220 is shown. The rotating member 220 includes a first rotating portion 2201 and a second rotating portion 2202. The first rotating portion 2201 and the second rotating portion 2202 are movably connected to each other, allowing the first rotating portion 2201 and the second rotating portion 2202 to rotate relative to each other about the same rotation axis. The first rotating portion 2201 and the second rotating portion 2202 are both provided with mounting holes, which are configured to be fixedly connected to the connecting seat 224 and the rotating mounting seat 2231, respectively.

[0128] As shown in Figures 28 and 29, Figure 28 shows a cross-sectional view of the connection between the lower cover 203 and the output panel 201, and Figure 29 shows an enlarged schematic view of the structure of Figure 28. It should be understood that the connection method of the upper cover 202 is basically the same as that of the lower cover 203. To avoid repetition, the connection of the lower cover 203 in this embodiment is described as an example.

[0129] During installation, the mounting holes on the first rotating portion 2201 mate with the holes on the connecting seat 224 in the lower cover 203 and are secured together using bolts, screws, or rivets. The mounting holes on the second rotating portion 2202 mate with the holes on the rotating mounting seat 2231 in the output panel 201 and are secured together using bolts, screws, or rivets. The fixing seat 2211 on the fixing member 221 mates with the fixing mounting seat 2232 in the output panel 201 and is secured together using bolts, screws, or rivets. For ease of installation, the bolts, screws, rivets, or other fixings securing the second rotating portion 2202 are installed in the opposite direction to those securing the fixing member 221. The lower cover 203 and the covering member 219 are connected using snaps or bolts to form a cavity that encloses the rotating portion 220. In this embodiment, the lower cover 203 and the covering member 219 are secured together using snaps. As shown in Figure 30, after the covering member 219 is installed, it also covers the space of the installation window 222.

[0130] As shown in Figures 31 and 32 , both the cover 219 and the lower cover 203 are provided with wiring openings 230 for routing wiring. Wiring harnesses required to connect the electronic components within the lower cover 203 are introduced into the vehicle body 100 through wiring openings 230 and connected to the relevant electronic components. Similarly, wiring openings 230 are also provided on the upper cover 202 for routing wiring, reducing wiring harness length and facilitating wiring.

[0131] As shown in Figure 33, an auxiliary switch 218 is provided on the lower cover 203. The lower cover 203 includes a housing 2031 and a base plate 2032. The auxiliary switch 218 is movably connected to the lower cover 203. An elastic member is disposed between the housing 2031 and the base plate 2032 to provide potential energy for the auxiliary switch 218 to move outward from the housing 2031. In other words, the elastic member is always in a compressed state, which enables the auxiliary switch 218 to move from the base plate 2032 toward the housing 2031. It should be noted that the elastic member may be a spring 225. When the lower cover 203 is closed, pressing the auxiliary switch 218 causes the auxiliary switch 218 to move toward the output panel 201, contacting the switch button 207 on the output panel 201 and controlling the switch button 207. When the auxiliary switch 218 is released, the elastic member resets the auxiliary switch 218 and separates the auxiliary switch 218 from the switch button 207 on the output panel 201.

[0132] It should be noted that a limiting protrusion is provided on the shell 2031, and correspondingly, an abutting protrusion is provided on the auxiliary switch 218, which abuts against the side of the limiting protrusion close to the bottom plate 2032. In this way, under the elastic force of the elastic member, the auxiliary switch 218 will not fall out of the shell 2032.

[0133] As shown in Figures 34 and 35 , the vehicle body 100 has a cavity inside that can accommodate the battery pack and other related electronic components, such as the inverter and MPPT assembly. The vehicle body 100 comprises a supporting frame 101. A vertical rear bracket 102 is mounted at the rear end of the frame 101, on which a rear cover 103 is mounted. The output panel 201 is positioned on the rear cover 103. Furthermore, an auxiliary bracket 228 is also located at the rear end of the frame 101. The bottom end of the auxiliary bracket 228 is fixedly connected to the frame 101. The auxiliary bracket 228 is a closed ring-shaped structure, its contour closely matching the outer contour of the output panel 201. Multiple connection points are evenly spaced around the outer contour of the auxiliary bracket 228, which is simultaneously fixedly connected to the rear cover 103. Adjacent connection points are spaced no more than 20 cm apart. The structural arrangement of the auxiliary bracket 228 enhances the overall strength of the output panel 201 and reduces deformation during use. The interfaces and electronic components related to the output panel 201 are integrated on the PCB board 227, and the PCB board 227 is fixedly connected to the inner side of the parking space cover 103. The PCB board 227 is located within the inner circle closed by the auxiliary bracket 228. A heat dissipation element 226 is also provided in the cavity of the vehicle body 100, and the heat dissipation element 226 is configured to dissipate heat from the PCB board 227. In this embodiment, optionally, the heat dissipation element 226 can be a heat dissipation fan. In order to avoid excessive temperature of electronic components in the vehicle body, the distance between the PCB board 227 and the edge of the battery assembly 104 is not less than 5 cm. For example, in this embodiment, the distance between the PCB board 227 and the edge of the battery assembly 104 is set to 10 cm. At the same time, when the heat dissipation element 226 is a heat dissipation fan, the heat dissipation element 226 and the heat dissipation fan in the battery assembly 104 are staggered.
