Description

Technical Field

[0001] This application relates to the field of vehicle engineering technology, and in particular to an electric all-terrain vehicle. Background Technology

[0002] An Electric All-Terrain Vehicle (E-ATV) is a multi-functional vehicle powered by electricity, capable of traversing complex terrains such as deserts, mud, snow, and mountains. It combines the off-road capabilities of traditional electric ATVs with the environmentally friendly and efficient characteristics of electrification technology, and is gradually becoming an important tool in outdoor sports, agriculture, rescue, and military fields.

[0003] However, due to the compact space of electric all-terrain vehicles, to avoid the risk of damage caused by exposed charging ports, the charging ports are generally located under the seats for concealment and protection. However, this results in inconvenience each time the charging is performed, and the wiring harness connected to the charging gun can obstruct the seat from closing when the charging gun is connected to the charging port. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an electric all-terrain vehicle with a battery charging interface that is more secure and easier to use.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An electric all-terrain vehicle includes a frame, a running gear, a body panel, a power battery, and a battery charging port. The running gear includes a front wheel. The body panel forms a side space for placing the legs of a driver or passenger. The body panel includes a front fender disposed between the side space and the front wheel. The power battery is supported by the frame, and the battery charging port is connected to the power battery and used to connect a charging gun. The front fender has an opening that extends through it, and an interface cover that can close the opening is provided at the opening. The body panel also includes an inner mudguard disposed between the front fender and the front wheel and connected to the front fender. The inner mudguard is recessed on one side of the front wheel, forming an interface mounting space between the inner mudguard and the front fender. The battery charging port is disposed in the interface mounting space. The interface cover has two states: open and closed. When the interface cover is open, the interface mounting space communicates with the side space through the opening. When the interface cover is closed, the interface mounting space is closed by the interface cover.

[0007] Furthermore, at least a portion of the front fender extends towards the rear and lower part of the electric all-terrain vehicle. When the battery charging port is arranged in the port mounting space, the port direction of the battery charging port is substantially perpendicular to the extension direction of the front fender, defining a reference plane perpendicular to the height direction of the frame. The port direction of the battery charging port has an inclination angle with the reference plane, the inclination angle ranging from 30° to 50°.

[0008] Furthermore, the tilt angle ranges from 35° to 45°.

[0009] Furthermore, the body panel also includes an interface fixing panel arranged in the interface mounting space, the interface fixing panel is mounted on the front baffle, and the battery charging interface is fixed to the interface fixing panel.

[0010] Furthermore, the interface cover is connected to the interface fixing panel via a pivot, allowing the interface cover to rotate relative to the interface fixing panel circumferentially along the pivot to open or close the opening.

[0011] Furthermore, the interface cover is rotatably connected to the front baffle via a pivot, allowing the interface cover to rotate relative to the front baffle along the circumference of the pivot to open or close the opening.

[0012] Furthermore, the electric all-terrain vehicle also includes a seat assembly with an interface cover lower than the upper surface of the seat assembly.

[0013] Furthermore, the body panel also includes a foot pedal for the driver and passengers to step on. The foot pedal is located below the side space and connected to the front panel. A foot pedal protective strip is provided on the outer edge of the foot pedal, and the foot pedal protective strip is detachably connected to the foot pedal.

[0014] Furthermore, the frame includes a main frame, the electrical system includes a transformer module, at least a portion of which is located behind the seat assembly, and the power battery has a high-voltage interface connected to a battery charging interface or the transformer module. The transformer module, the battery charging interface, and the high-voltage interface are all oriented on the same side of the main frame.

[0015] Furthermore, the frame also includes a subframe, which is detachably mounted on the main frame and located above the main frame. At least a portion of the body panel in front of the seat assembly surrounds the subframe to form a cargo box front space. At least a portion of the power battery is arranged in the cargo box front space, which is connected to the interface mounting space.

[0016] With the above configuration, the front fender has an opening that extends through it, and an interface cover is provided on the front fender to close the opening. The interface cover has two states: open and closed. The inner fender is connected to the front fender and is positioned between the front fender and the seat assembly. The inner fender is located between the front wheel and the front fender, forming an interface mounting space between the inner fender and the front fender. This interface mounting space communicates with the outside through the opening, and the battery charging interface is located within this interface mounting space. This design avoids exposing the battery charging interface, making it safer and easier to use. Attached Figure Description

[0032] like Figure 1 As shown, this application provides an electric all-terrain vehicle 100, which includes a frame 11, a body panel 12, a suspension system 13, a running system, a seat assembly 14, a cargo box 15, and a steering system 16. The frame 11 forms the basic framework of the electric all-terrain vehicle 100. The body panel 12 is at least partially mounted on the frame 11. The running system is at least partially located below the frame 11. The suspension system 13 connects the frame 11 and the running system, and is used to transmit forces and torques between the running system and the frame 11. At least a portion of the seat assembly 14 is mounted on the frame 11, and the seat assembly 14 is available for a rider. At least a portion of the cargo box 15 is located below the seat assembly 14. The steering system 16 is fixed to the frame and is connected to the running system to control the direction of travel of the electric all-terrain vehicle 100. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The electric all-terrain vehicle 100 is shown in the front, rear, left, right, up, and down directions.

[0033] It should be noted that in the following description of the technical solution of this application, the length direction of the frame 11 is parallel to the front-rear direction of the electric all-terrain vehicle 100, the width direction of the frame 11 is parallel to the left-right direction of the electric all-terrain vehicle 100, and the height direction of the frame 11 is parallel to the up-down direction of the electric all-terrain vehicle 100.

[0034] like Figure 2 As shown, in one implementation, the frame 11 includes a main frame 111, a subframe 112 (front cargo box support, not shown), and a rear cargo box support 113. The subframe 112 is located above the main frame 111 and is detachably connected to the main frame 111. The subframe 112 supports the seat assembly 14. The main frame 111 includes a front frame 1111, a middle frame 1112, and a rear frame 1113, which are sequentially distributed from front to rear. The front frame 1111, the middle frame 1112, and the rear frame 1113 are integrally formed. The drive assembly 17 is mounted on the rear frame 1113, and at least a portion of the power battery 17 is located below the subframe 112.

[0035] like Figures 3 to 5 As shown, to clearly illustrate the technical solution of this application, the vehicle body panel 12 is sequentially divided into a front panel 121, a middle panel 122, and a rear panel 123. In one implementation, the front panel 121 covers at least a portion of the front frame 1111, the middle panel 122 covers at least a portion of the middle frame 1112, and the rear panel 123 covers at least a portion of the rear frame 1113. The front panel 121 includes a battery cover 1211, which is located in front of the seat assembly 14 and cooperates with the seat assembly 14 to cover the subframe 112 in the height direction of the vehicle frame.

[0036] In one implementation, the cargo box 15 includes a centrally located cargo box 151 mounted on the subframe 112 and located below the seat assembly 14. A gap extending in the height direction exists between the front panel of the centrally located cargo box 151 and the seat assembly 14. The space in front of the centrally located cargo box 151 is defined as the front cargo box space 1511. The front cargo box space 1511 is covered in the height direction by the seat assembly 14 and the battery cover 1211. The front cargo box space 1511 communicates with the internal space of the centrally located cargo box 151 through the gap. The body panel 12 includes an interface fixing structure 124, which is disposed in the front cargo box space 1511 and connected to the subframe 112. The electric all-terrain vehicle 100 also includes an electrical system 19. The electrical system 19 includes a device interface 1918 capable of connecting to a mobile terminal, low-voltage electrical appliances 191 such as a controller 1911, and high-voltage electrical appliances 193 such as a transformer module 1931. The device interface 1918 is mounted on the interface fixing structure 124.

[0037] When the seat assembly 14 is in the open position, the interior space of the center cargo box 151 is connected to the exterior space, allowing items to be placed in or removed from the center cargo box 151. When the seat assembly 14 is in the closed position, the seat assembly 14 and the battery cover 1211 cover the front cargo box space 1511 and the interior space of the center cargo box 151, with the front cargo box space 1511 connected to the interior space of the center cargo box 151 through a gap.

[0038] For example, the mobile terminal can be placed inside the central cargo box 151 and connected to the device structure via a data cable / charging cable, which passes through the gap when the seat assembly 14 is closed. When the driver / passenger is driving the electric all-terrain vehicle 100, the mobile terminal stored inside the central cargo box 151 can be charged, or a data connection can be established between the mobile terminal and the electric all-terrain vehicle 100.

[0039] Furthermore, the subframe 112 includes a seat fastener 1123 for securing the seat assembly 14 and a pair of subframe tubes 1124 extending along the length direction. The seat fastener 1123 is disposed between the pair of subframe tubes 1124 and located in front of the central cargo box 151. When the seat assembly 14 is installed on the subframe 112, at least a portion of the seat assembly 14 is disposed on the seat fastener 1123, and the seat assembly 14 is limited in the length direction by the front seat fastener 1123. To facilitate the installation of the device interface 1918 and prevent the device interface 1918 from being exposed when the seat assembly 14 is open, an interface fixing structure 124 is installed on the seat fastener 1123. Since the interface fixing structure 124 is located in front of the seat fastener 1123, when the device interface 1918 is disposed on the interface fixing structure 124, the device interface 1918 can be covered by the battery cover 1211, improving the protection of the device interface 1918.

[0040] In one implementation, the seat assembly 14 includes a front seat cushion 141 and a rear seat cushion 142 distributed along its length. The front seat cushion 141 extends forward and upward toward the electric all-terrain vehicle 100, and the rear seat cushion 142 extends substantially horizontally. The front seat cushion 141 and the rear seat cushion 142 are integrally formed. Viewed from the height direction, the central cargo box 151 overlaps with at least a portion of the front seat cushion 141, creating a gap between the front panel and the front seat cushion 141.

[0041] Specifically, the front seat cushion 141 is located in front of the rear seat cushion 142. When the seat assembly 14 is closed, the rear seat cushion 142 covers part of the opening of the central cargo box 151, and the front space 1511 of the cargo box can communicate with the opening of the central cargo box 151 through the gap under the front seat cushion 141, thereby connecting the interior space of the central cargo box 151.

[0042] For example, the front panel is located below the front seat cushion 141. Since the front seat cushion 141 extends forward and upward, there is a gap in the height direction between the front cargo box panel and the front seat cushion 141, which allows a data cable to pass through so that the device interface 1918 can be connected to the mobile terminal.

[0043] As an alternative implementation, the seat assembly 14 includes a front seat cushion 141 and a rear seat cushion 142 distributed along its length. The front seat cushion 141 is located in front of the rear seat cushion 142 and extends upward and forward of the electric all-terrain vehicle 100. The rear seat cushion 142 extends substantially horizontally. Viewed from the height direction, the central cargo box 151 completely overlaps with the rear seat cushion 142. An upward-facing notch is provided on the upper edge of the front panel, forming a gap between the notch and the rear seat cushion 142.

[0044] Specifically, the front seat cushion 141 is located in front of the rear seat cushion 142. When the seat assembly 14 is closed, the rear seat cushion 142 completely covers the upper part of the interior space of the center cargo box 151, and the upper part of the interior space of the center cargo box 151 is closed. The front space 1511 of the cargo box can communicate with the opening of the center cargo box 151 through the notch, thereby connecting the interior space of the center cargo box 151.

[0045] In embodiments of this application, the device interface 1918 includes, but is not limited to, a charging interface, a data interface, and a cigarette lighter. The charging interface provides a way to charge the occupant's mobile terminal, such as a mobile phone or tablet. The data interface facilitates data transfer between the mobile terminal and the electric all-terrain vehicle 100. Exemplarily, the charging interface and data interface are integrated into the same USB interface, enabling device charging while data is being transmitted. The cigarette lighter draws energy from the battery 192 to heat components such as a metal heating element or a metal heating wire, providing a fire source for lighting cigarettes.

[0046] The interface mounting structure 124 has a mounting hole extending through it, through which at least a portion of the device interface 1918 passes. Exemplarily, the charging interface, data interface, and cigarette lighter pass through the mounting hole, and the ends of the charging interface, data interface, and cigarette lighter opposite the front seat 141 are electrically connected to the battery 192 via a wiring harness.

[0047] In one implementation, the controller 1911 includes a key controller 1911c, which is positioned in front of the central cargo box 151. As part of the PEPS (Passive Entry Passive Start) system, the key controller 1911c signals the electric all-terrain vehicle 100 to unlock or start when the occupant approaches with the key. Viewed in the width direction, at least a portion of the key controller 1911c is located above the subframe 112. A transformer module 1931 is positioned behind the central cargo box 151 and fixed to the rear frame 1113.

[0048] It should be noted that the transformer module 1931 is used for voltage conversion. For example, the battery 192 is connected to the power battery 18 through the transformer module 1931, which converts the high voltage of the power battery 18 into a low voltage that can charge the battery 192. Alternatively, the power battery 18 is connected to the drive assembly 17 through the transformer module 1931, which converts the output voltage of the power battery 18 into a drive voltage that acts on the drive assembly 17. Or, the transformer module 1931 is connected to the power battery 18, which converts AC power into DC power to charge the power battery 18. Therefore, the transformer module 1931, as a high-voltage electrical appliance, is positioned behind the centrally located cargo box 151 to increase the distance between the transformer module 1931 and the key controller 1911c.

[0049] With the above settings, on the one hand, signal interference from the frame 11 to the key controller 1911c can be avoided; on the other hand, the radiation signal generated by the transformer module 1931 during operation can be avoided from interfering with the normal operation of the key controller 1911c. At the same time, the electronic key also improves the convenience of starting.

[0050] As described above, a seat fastener 1123 is provided between a pair of subframe tubes 1124, and an interface fixing structure 124 for mounting the equipment interface 1918 is provided in front of the seat fastener 1123. In the embodiment of this application, the key controller 1911c is disposed on the upper surface of the interface fixing structure 124, such that at least a portion of the key controller 1911c is located above the subframe 112 when viewed from the width direction. The interface fixing structure 124 further raises the arrangement height of the key controller 1911c, avoiding signal interference from the frame to the key controller 1911c.

[0051] like Figure 5 and Figure 6As shown, in one implementation, the distance between the key controller 1911c and the transformer module 1931 along the length direction is defined as a first length D4, and the length of the frame extending along the length direction is defined as a second length D5. In one implementation, the ratio between the first length D4 and the second length D5 ranges from 0.5 to 0.7. Further, the ratio ranges from 0.55 to 0.65. More preferably, the ratio is 0.6. It should be noted that, given a fixed frame length, if the ratio is too small, the distance between the key controller 1911c and the transformer module 1931 will be too small, and the radiation signal generated by the transformer module 1931 may affect the key controller 1911c. If the ratio is too large, the distance between the key controller 1911c and the transformer module 1931 will be too large, and the key controller 1911c will be positioned too close to the front frame 1111. If the electronic key is located behind the electric all-terrain vehicle 100, the key controller 1911c may be unable to receive signals transmitted by the transformer module 1931. Through the above settings, the signal reception effect of the key controller 1911c in all directions is improved while avoiding signal interference from the transformer module 1931.

[0052] Furthermore, a longitudinal plane 103 perpendicular to the width direction is defined, which substantially bisects the vehicle frame. The key controller 1911c is symmetrically distributed about the longitudinal plane 103. Because the interface fixing structure 124 is symmetrically distributed about the longitudinal plane 103, if a key paired with the key controller 1911c is close to the vehicle, the key controller 1911c will maintain a basically consistent reception effect of the signal generated by the key in the width direction.

[0053] like Figure 7 As shown, in one implementation, with the rotation axis of the front wheel parallel to the width direction, the distance between the key controller 1911c and the rotation axis of the front wheel is defined as a first distance D6, and the distance between the key controller 1911c and the rotation axis of the rear wheel is defined as a second distance D7. The ratio between the first distance D6 and the second distance D7 ranges from 0.35 to 0.53. Further, the ratio ranges from 0.38 to 0.47. More preferably, the ratio is 0.43. With the above settings, the key controller 1911c is positioned relatively close to the front wheel in the length direction, improving the sensing sensitivity of the key controller 1911c when the driver or passenger uses the electric all-terrain vehicle 100.

[0054] like Figure 8 As shown, in one implementation, the front cover 121 also includes a battery cover 1211 disposed in front of the seat assembly 14 (see Figure 1211). Figure 4The battery cover 1211 is used in conjunction with the seat assembly 14 to cover the subframe 112 in the height direction. The electrical system 19 also includes an NFC (Near Field Communication) reader 196 mounted on the battery cover 1211, at least a portion of which passes through the battery cover 1211 and extends into the space beneath it. The NFC reader 196 is equipped with an NFC key; inserting the NFC key into the NFC reader 196 enables its use in conjunction with the NFC key to control the start of the electric all-terrain vehicle 100.

[0055] The NFC reader 196 is configured as a card reader and is installed on the battery cover 1211. The NFC key is inserted into the card reader to control the start of the electric all-terrain vehicle 100. This configuration reduces the distance between the NFC key and the NFC reader 196, increases the reading sensitivity of the NFC reader 196, improves the convenience of using the NFC key for drivers and passengers, and reduces the risk of key loss.

[0056] Specifically, at least a portion of the battery cover 1211 is recessed towards the subframe 112 to form a rearward and upward sloping surface. At least a portion of the NFC reader 196 passes through this sloping surface. The battery cover 1211 has a drainage hole 1211a extending through it, located below the sloping surface. For example, when it rains, rainwater enters the NFC reader 196 and can move down the sloping surface to the drainage hole 1211a, where it is drained. This design increases the water resistance of the NFC reader 196, thereby increasing its durability.

[0057] like Figure 8 As shown, as an optional implementation, the NFC reader 196 includes a housing 1961 and a rubber component 1962. The housing 1961 forms a reading space, and the rubber component 1962 is disposed on the inner wall of the housing 1961 and arranged around at least a portion of the reading space. The reading space is used to allow at least a portion of the NFC key to remain inside the NFC reader 196, and the rubber component 1962 is used to reduce the risk of damage to the NFC key due to collisions with the housing 1961 caused by bumps during the operation of the electric all-terrain vehicle 100.

[0058] Specifically, the NFC reader 196 also includes a PCB board 1963 (Printed Circuit Board), and the NFC key includes an NFC chip. An NFC antenna is arranged on the PCB board 1963. The NFC antenna is used to detect the NFC key inserted into the NFC reader 196 and exchange data with the NFC chip in the NFC key. The distance between the PCB board 1963 and the NFC key inserted into the NFC reader 196 is fixed, and the PCB board 1963 is potted to improve its dust and water resistance and the stability of NFC key detection.

[0059] Furthermore, a notch is formed on the housing 1961 connecting the card reader space and the front cargo space 1511. The NFC card reader 196 also includes an elastic member 1964 disposed at the notch. The elastic member 1964 is connected to the housing 1961 by fasteners. When an NFC key adapted to the NFC card reader 196 is inserted into the card reader space, the elastic member 1964 abuts against the NFC key in a direction perpendicular to the insertion direction of the NFC key, thereby restricting the movement of the NFC key in the card reader space perpendicular to the insertion direction of the NFC key. The size of the notch is approximately the size of a human finger, making it convenient for drivers and passengers to pick up the NFC key.

[0060] For example, the elastic element 1964 is configured as a spring sheet, and the side of the spring sheet facing away from the notch is connected to the housing 1961 by two screws. When the spring sheet needs to be replaced, it can be replaced simply by removing the two screws.

[0061] By setting the easily replaceable elastic element 1964 as described above, the insertion direction of the NFC key in the card reader space is limited to be perpendicular to the NFC key, and the risk of the NFC key being removed from the NFC card reader 196 when not pulled out by the rider is reduced.

[0062] As an optional implementation, the elastic element 1964 includes an abrasion-resistant plastic part, which is mounted on the end of the elastic element 1964 that abuts against the NFC key. The abrasion-resistant plastic part is used to prevent metal-to-metal friction between the NFC key and the elastic element 1964 after the NFC key is inserted into the card reader space, thereby protecting the appearance of the NFC key and improving the durability of the NFC card reader 196 and the NFC key.

[0063] It should be noted that NFC chips can be learned by other mobile terminals, allowing drivers and passengers to use mobile terminals that have learned NFC chips instead of NFC keys, thus making it easier to start the vehicle.

[0064] For example, when a driver or passenger needs to start the electric all-terrain vehicle 100, the NFC key is inserted into the NFC reader 196 through the notch on the housing 1961, causing the NFC key to contact the abrasion-resistant plastic part. The NFC antenna on the PCB board 1963 detects the inserted NFC key and exchanges data with the NFC chip in the key to start the electric all-terrain vehicle 100. Furthermore, while the electric all-terrain vehicle 100 is in motion, the elastic element 1964 keeps the NFC key within the reader space, reducing the risk of the NFC key falling out.

[0065] like Figure 9 As shown, in one implementation, the electrical system 19 also includes a lighting assembly 1919, which includes a headlight 1919a ​​mounted on the front fender 1212. The front fender 1212 has a first storage compartment 1212b recessed downwards towards the electric all-terrain vehicle 100, and the front rack cover 1213 has a front rack storage opening 1213b extending through it. The opening of the first storage compartment 1212b coincides with the front rack storage opening 1213b in the height direction. This results in a deeper storage space for the front rack cover 1213, increasing its storage capacity and thus increasing the storage space of the electric all-terrain vehicle 100.

[0066] As one implementation, a reference plane 104 perpendicular to the height direction is defined. The orthographic projection of the front shelf storage opening 1213b onto the reference plane 104 is defined as the storage slot projection, and the orthographic projection of the front shelf cover 1213 onto the reference plane 104 is defined as the shelf projection. The ratio of the storage slot projection to the shelf projection ranges from 0.2 to 0.3. Further, the ratio ranges from 0.23 to 0.27. More preferably, the ratio is 0.25. It should be noted that if the ratio of the storage slot projection to the shelf projection is too small, the internal space of the first storage slot 1212b will be limited, and larger items will not be able to fit into the first storage slot 1212b. If the ratio of the storage slot projection to the shelf projection is too large, the first storage slot 1212b will affect the arrangement of other components.

[0067] As one implementation, when viewed from the height direction, the first storage compartment 1212b overlaps with the headlight 1919a, and the first storage compartment 1212b is located above the headlight 1919a.

[0068] Specifically, the number of first storage compartments 1212b is set to two, and a longitudinal plane 103 perpendicular to the width direction is defined. The longitudinal plane 103 basically bisects the frame, and the two first storage compartments 1212b are basically symmetrically distributed about the longitudinal plane 103.

[0069] like Figure 10 As shown, in one implementation, the front storage space, consisting of the first storage compartment 1212b and the front shelf storage opening 1213b, has a depth range D8 extending along the height direction of 100mm to 140mm. Further, the depth range D8 is 106mm to 132mm. More preferably, the depth range D8 is 112mm to 125mm. It should be noted that if the depth range D8 is too small, the front storage space will have poor capacity and will not meet the storage needs of the driver and passengers. If the depth range D8 is too large, the bottom of the first storage compartment 1212b will contact the headlight 1919a, affecting the arrangement of the headlight 1919a.

[0070] As one implementation, the ratio of the depth D9 of the first storage compartment 1212b to the depth D10 of the front shelf storage opening 1213b ranges from 1.1 to 1.7. Further, the ratio ranges from 1.21 to 1.53. More preferably, the ratio is 1.43. Through the above arrangement, given a fixed depth of the front storage space, the depth distribution between the first storage compartment 1212b and the front shelf storage opening 1213b is made more reasonable, and the storage capacity of the first storage compartment 1212b is improved.

[0071] Furthermore, the front shelf cover 1213 is provided with several fixing parts distributed around the outer edge of the front shelf storage opening 1213b. The fixing parts are used to fix the storage accessories so that the front shelf storage opening 1213b can be covered by the storage accessories.

[0072] For example, the storage accessory is configured as a storage cover or a mesh bag, which is detachably connected to the front shelf cover 1213 via a snap-fit ​​structure.

[0073] As one implementation, at least a portion of the rear frame 1113 is positioned behind the subframe 112. The rear fender 1231 has a second storage compartment 1231b recessed downwards from the electric all-terrain vehicle 100 (see...). Figure 9 The rear cover 123 also includes a rear shelf cover 1232, which covers the rear mudguard 1231. The rear shelf cover 1232 has a rear shelf storage opening 1232b that extends through it. The rear shelf storage opening 1232b coincides with the opening of the second storage slot 1231b in the height direction, thereby improving the storage capacity of the rear shelf cover 1232.

[0074] The lighting assembly 1919 also includes a taillight 1919b mounted on the rear fender 1231. When viewed in the height direction, the second storage compartment 1231b overlaps with the taillight 1919b and is located above the taillight 1919b.

[0075] The rear shelf cover 1232 has several fixing parts distributed around the outer edge of the rear shelf storage opening 1232b. The fixing parts are used to connect storage accessories that cooperate with the rear shelf cover 1232, and the rear shelf storage opening 1232b can be covered by the storage accessories.

[0076] For example, the storage accessory is configured as a covering mesh, which is attached to a plurality of fixed parts distributed around the outer edge of the rear shelf storage opening 1232b, and when viewed in the longitudinal direction, the covering mesh is at least partially located below the rear shelf storage opening 1232b, so as to prevent items in the second storage compartment 1231b from jumping out of the second storage compartment 1231b due to bumps during the driving of the electric all-terrain vehicle 100.

[0077] like Figure 11 and Figure 12 As shown, in one implementation, the body panel 12 forms a side space 102 for placing the legs of the driver and passengers. The front panel 121 includes a front fender 1217, which is connected to the front fender 1212 and arranged between the side space 102 and the front wheel. The front fender 1217 has an opening that extends through it, and an interface cover 1217a is provided at the opening to close it. The front panel 121 also includes an inner fender 1218, which is connected to the front fender 1217 and located between the front wheel and the front fender 1217. The inner fender 1218 is recessed on the front wheel side, forming an interface mounting space 105 between the inner fender 1218 and the front fender 1217. The interface mounting space 105 can communicate with the outside through the opening in the front fender 1217. The electrical system 19 also includes a battery charging interface 197 for connecting a charging gun. The battery charging interface 197 is electrically connected to the power battery 18 and is arranged in the interface installation space 105.

[0078] The interface cover 1217a has two states: open and closed. When the interface cover 1217a is open, the interface mounting space 105 is connected to the side space 102 through the opening, and the charging gun can pass through the opening to connect to the battery charging interface 197. When the interface cover 1217a is closed, the interface mounting space 105 is closed by the interface cover 1217a.

[0079] In this embodiment, a front fender 1217 and an inner fender 1218 are provided between the front fender 1212 and the seat assembly 14, forming an interface mounting space 105. The battery charging port 197 is arranged within this space, preventing it from being exposed. The front fender 1217 has an opening and is fitted with an interface cover 1217a to close it. When the driver or passenger uses the battery charging port 197, they can simply open the cover 1217a to directly access the port. This design improves the durability of the battery charging port 197, reduces the risk of water ingress, and increases charging convenience.

[0080] like Figure 12 As shown, in one implementation, at least a portion of the front baffle 1217 extends rearward and downward toward the electric all-terrain vehicle 100. When the battery charging port 197 is arranged in the port mounting space 105, the port direction of the battery charging port 197 is substantially perpendicular to the extension direction of the front baffle 1217, creating an angle θ between the port direction of the battery charging port 197 and the reference plane 104. A reference line 106 is defined, parallel to the port direction of the battery charging port 197. The angle between the reference line 106 and the horizontal reference plane 104 is the aforementioned angle θ, which ranges from 30° to 50°. Further, the angle θ between the port direction of the battery charging port 197 and the reference plane 104 ranges from 32° to 48°. More preferably, the angle θ between the port direction of the battery charging port 197 and the reference plane 104 ranges from 35° to 45°. It should be noted that if the tilt angle θ between the interface direction of the battery charging interface 197 and the reference plane 104 is outside the above range, it will be inconvenient for the driver and passengers to insert charging cables such as data cables into the battery charging interface 197 when using the battery charging interface 197, thus reducing the comfort of the human-machine interaction of the electric all-terrain vehicle 100.

[0081] As one implementation, the front cover 121 also includes an interface fixing panel 1219 arranged in the interface mounting space 105. The interface fixing panel 1219 is mounted on the front baffle 1217, and the battery charging interface 197 is fixed to the interface fixing panel 1219.

[0082] Specifically, the interface cover 1217a is connected to the interface fixing panel 1219 via a pivot, so that the interface cover 1217a can rotate relative to the interface fixing structure 124 in the circumferential direction along the pivot to open or close the opening of the front baffle 1217.

[0083] Optionally, the interface cover 1217a is rotatably connected to the front baffle 1217 via a pivot, so that the interface cover 1217a can rotate relative to the front baffle 1217 in the circumferential direction of the pivot to open or close the opening of the front baffle 1217.

[0084] This application does not specifically limit the installation position of the interface cover 1217a (such as the interface fixing structure 124 and the front baffle 1217 mentioned above), and any installation form that can realize the opening and closing of the interface cover 1217a, such as a buckle, hinge, or locking hook, is within the scope of protection claimed in this application.

[0085] For example, the interface cover 1217a is rotatably connected to the front baffle 1217 via a pivot. The interface cover 1217a is configured as a press-type self-locking cover, which includes a locking mechanism. By pressing the interface cover 1217a, the locking mechanism locks the interface cover 1217a to close the opening of the front baffle 1217, or releases the locking mechanism and springs the interface cover 1217a open, allowing the interface cover 1217a to rotate relative to the front baffle 1217 in the circumferential direction along the pivot, thereby opening the opening of the front baffle 1217.

[0086] With the above configuration, the battery charging interface 197 is fixed to the interface fixing panel 1219 installed on the front baffle 1217, thus securing the battery charging interface 197 within the interface mounting space 105. This prevents the battery charging interface 197 from wobbling within the interface mounting space 105, which would prevent the charging cable from being inserted into the battery charging interface 197 and thus make it difficult to use the battery charging interface 197. Simultaneously, the interface cover 1217a is connected to the front baffle 1217 or the interface fixing panel 1219 via a pivot, allowing the opening or closing of the opening in the front baffle 1217 to be controlled by opening or closing the interface cover 1217a. This enhances the protection of the battery charging interface 197 while improving the convenience of using it.

[0087] In one implementation, the electrical system 19 includes a transformer module 1931, at least a portion of which is located behind the seat assembly 14. The power battery 18 has a high-voltage interface (not shown) connected to either the battery charging interface 197 or the transformer module 1931. The transformer module 1931, the battery charging interface 197, and the high-voltage interface are all oriented on the same side of the main frame 111.

[0088] In this embodiment, the transformer module 1931 is arranged on the left side of the main frame 111, the battery charging interface 197 is covered by the front baffle 1217 on the left side of the seat assembly 14, and the power battery 18 has a high-voltage interface connected to the battery charging interface 197 or the transformer module 1931. The high-voltage interface faces the left side of the electric all-terrain vehicle 100, so that the high-voltage wiring harness 1942 connecting the transformer module 1931, the battery charging interface 197 and / or the power battery 18 is arranged on the left side of the main frame 111.

[0089] Specifically, the transformer module 1931 and the battery charging interface 197 are arranged on the left side of the electric all-terrain vehicle 100, and the high-voltage interface on the power battery 18 is also arranged on the left side of the electric all-terrain vehicle 100. This makes the high-voltage interface connecting the transformer module 1931, the battery charging interface 197, and the power battery 18, as well as the high-voltage wiring harness 1942, all located on the left side of the vehicle frame, reducing the difficulty of arranging the high-voltage wiring harness 1942 and making the wiring harness arrangement of the entire vehicle more reasonable.

[0090] Furthermore, the interface cover 1217a is lower than the upper surface of the seat assembly 14, or in other words, the battery charging interface 197 covered by the interface cover 1217a is lower than the upper surface of the seat assembly 14, thereby facilitating the connection of the charging gun to the battery charging interface 197.

[0091] At least a portion of the body panel 12 in front of the seat assembly 14 forms a cargo box front space 1511 around the subframe 112. At least a portion of the power battery 18 is arranged in the cargo box front space 1511. The cargo box front space 1511 communicates with the interface mounting space 105 to facilitate the wiring harness arrangement between the battery charging interface 197 and the power battery 18.

[0092] As one implementation, the central cover 122 also includes a foot pedal 1221 for the driver and passengers to step on. The foot pedal 1221 is located below the front baffle 1217 and connected to the front baffle 1217. A foot pedal protective strip 1221a is provided on the outer edge of the foot pedal 1221, and the foot pedal protective strip 1221a is detachably connected to the foot pedal 1221.

[0093] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
