The main frame 111 comprises a front frame 1111, a middle frame 1112 and a rear frame 1113 which are sequentially distributed from front to rear and integrally formed. The electric drive assembly 17 is installed on the rear frame 1113, and at least part of the power battery 17 is located below the sub-frame 112.

[0035] As shown in the figure, Figures 3 to 5 For the purpose of clearly illustrating the technical solutions of the present application, the vehicle body cover 12 is sequentially divided into a front cover 121, a middle cover 122 and a rear cover 123. As an implementation manner, the front cover 121 is used for covering at least part of the front frame 1111, the middle cover 122 is used for covering at least part of the middle frame 1112, and the rear cover 123 is used for covering at least part of the rear frame 1113. The front cover 121 comprises a battery upper cover 1211, which is located in front of the seat 14 and cooperates with the seat 14 to cover the sub-frame 112 in the height direction of the vehicle frame.

[0036] As an implementation manner, the cargo box 15 comprises a middle cargo box 151 which is installed on the sub-frame 112 and located below the seat 14, the middle cargo box 151 forms a cargo box inner space, the front part of the middle cargo box 151 comprises a front panel 1512, and the front panel 1512 of the middle cargo box 151 has a gap extending in the height direction between the seat 14, the space in front of the middle cargo box 151 is defined as a cargo box front space 1511, the cargo box front space 1511 is covered by the seat 14 and the battery upper cover 1211 in the height direction, and the cargo box front space 1511 is in communication with the cargo box inner space through the gap. The vehicle body cover 12 comprises an interface fixing structure 124 which is directly or indirectly installed on the sub-frame 112 and arranged in the cargo box front space 1511. The electric all-terrain vehicle 100 further comprises an electrical system 19 which comprises a low-voltage electrical apparatus 191 and a high-voltage electrical apparatus 193, wherein the low-voltage electrical apparatus 191 comprises a controller 1911 and a device interface 1918 which can be connected with a mobile terminal, and the high-voltage electrical apparatus 193 comprises a voltage conversion module 1931.

[0037] In the embodiment of the present application, the device interface 1918 is installed on the interface fixing structure 124, when the mobile terminal is connected with the device interface 1918 through a signal line, the signal line can extend from the cargo box inner space to the cargo box front space 1511 through the gap and be connected to the device interface 1918.

[0038] When the seat 14 is in the open state, the in-trunk space is in communication with the outside space, and at this time, the article can be put into or taken out from the middle trunk 151. When the seat 14 is in the closed state, the seat 14 covers the in-trunk space, and at this time, the trunk front space 1511 is in communication with the in-trunk space through the gap. The mobile terminal can be placed in the in-trunk space, and in the case that the seat 14 is in the closed state, the signal line passes through the gap and extends to the trunk front space 1511, so that the signal line can be connected with the device interface 1918. Based on the above arrangement, in the case that the driver drives the electric all-terrain vehicle 100, the vehicle can charge the mobile terminal stored in the in-trunk space or make the mobile terminal realize data transmission with the vehicle.

[0039] Further, the sub-frame 112 includes a seat fixing member 1123 for fixing the seat 14 and a pair of sub-frame tubes 1124 extending in the length direction, and the seat fixing member 1123 is arranged between the pair of sub-frame tubes 1124 and in front of the middle trunk 151. When the seat 14 is installed on the sub-frame 112, at least part of the seat 14 is arranged on the seat fixing member 1123, and the seat 14 is limited in the length direction by the seat fixing member 1123 on the front side. In order to realize the installation of the device interface 1918 and avoid the exposure of the device interface 1918 when the seat 14 is opened, the interface fixing structure 124 is installed on the seat fixing member 1123, and since the interface fixing structure 124 is arranged in front of the seat fixing member 1123, when the device interface 1918 is arranged on the interface fixing structure 124, the device interface 1918 can be covered by the battery upper cover 1211, thereby improving the protection effect of the device interface 1918.

[0040] As an implementation manner, the seat 14 includes a front seat cushion 141 and a rear seat cushion 142 distributed in the length direction, the front seat cushion 141 extends to the front upper side of the electric all-terrain vehicle 100, the rear seat cushion 142 extends substantially in the horizontal direction, and the front seat cushion 141 and the rear seat cushion 142 are integrally formed. From the height direction, the middle trunk 151 overlaps at least part of the front seat cushion 141, so that the gap is formed between the front panel 1512 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 14 is in the closed state, the rear seat cushion 142 covers part of the opening of the middle trunk 151, and the trunk front space 1511 can be in communication with the opening of the middle trunk 151 through the gap below the front seat cushion 141, and then in communication with the in-trunk space.

[0042] Exemplarily, the front panel 1512 is located below the front seat cushion 141, and since the front seat cushion 141 extends forwardly and upwardly, there is a gap between the front cargo box panel and the front seat cushion 141 in the height direction, which can be used for the data line to pass through to connect the device interface 1918 with the mobile terminal.

[0043] As an optional implementation, the seat 14 comprises a front seat cushion 141 and a rear seat cushion 142 distributed along the length direction, the front seat cushion 141 is located in front of the rear seat cushion 142, the front seat cushion 141 extends forwardly and upwardly of the electric all-terrain vehicle 100, and the rear seat cushion 142 extends substantially horizontally, and from the height direction, the middle cargo box 151 completely overlaps the rear seat cushion 142, and the upper edge of the front panel 1512 is provided with an upwardly facing notch, which forms a gap with the rear seat cushion 142

[0044] Specifically, the front seat cushion 141 is located in front of the rear seat cushion 142, and when the seat 14 is in the closed state, the rear seat cushion 142 completely covers the upper part of the cargo box inner space, and the upper part of the cargo box inner space is in a closed state, and the cargo box front space 1511 can be communicated with the opening of the middle cargo box 151 through the notch, and then communicated with the cargo box inner space.

[0045] In the embodiments of the present application, the device interface 1918 includes but is not limited to a charging interface, a data interface, and a cigarette lighter. The charging interface is used to provide an interface for charging the mobile terminal of the driver or passenger, such as a mobile phone, a tablet computer, etc., and the data interface is used to transmit data between the mobile terminal and the electric all-terrain vehicle 100. Exemplarily, the charging interface and the data interface are integrated on the same USB interface, which can charge the device while transmitting data. The cigarette lighter obtains energy from the storage battery 192 to heat components such as metal heating sheets or metal heating wires to provide a fire source for the lighter.

[0046] The interface fixing structure 124 has mounting holes penetrating through opposite two end faces thereof, and at least part of the device interface 1918 passes through the mounting holes. Exemplarily, the charging interface, the data interface, and the cigarette lighter pass through the mounting holes, and one end of the charging interface, the data interface, and the cigarette lighter away from the front seat cushion 141 is electrically connected to the storage battery 192 through a wire harness.

[0047] As an implementation, the controller 1911 includes a key controller 1911c, which is arranged in front of the mid-box 151. The key controller 1911c is part of the PEPS (Passive Entry Passive Start) system, and when the driver carrying the key approaches the electric all-terrain vehicle 100, the vehicle receives a signal to complete the unlocking or starting. At least part of the key controller 1911c is above the sub-frame 112 when viewed in the width direction. The transformer module 1931 is arranged behind the mid-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, and the high voltage of the power battery 18 is converted into low voltage through the transformer module 1931, which can charge the battery 192. Alternatively, the power battery 18 is connected to the electric drive assembly 17 through the transformer module 1931, and the output voltage of the power battery 18 is converted into the drive voltage acting on the electric drive assembly 17 through the transformer module 1931. Alternatively, the transformer module 1931 is connected to the power battery 18, and the transformer module 1931 converts alternating current into direct current to charge the power battery 18. It can be seen that the transformer module 1931 is a high-voltage electrical appliance, which is arranged behind the mid-box 151 to increase the distance between the transformer module 1931 and the key controller 1911c.

[0049] Through the above arrangement, on the one hand, the signal interference of the frame 11 on the key controller 1911c can be avoided; on the other hand, the radiation signal generated by the transformer module 1931 when working can also avoid interfering with the normal work of the key controller 1911c, and the electronic key also improves the convenience of starting.

[0050] According to the foregoing, a seat fixing member 1123 is arranged between a pair of sub-frame pipes 1124, and an interface fixing structure 124 for mounting the equipment interface 1918 is arranged in front of the seat fixing member 1123. In the embodiment of the application, the key controller 1911c is arranged on the upper surface of the interface fixing structure 124, and at least part of the key controller 1911c is above the sub-frame 112 when viewed in the width direction. The arrangement height of the key controller 1911c is further raised by the interface fixing structure 124, so as to avoid the signal interference of the frame on the key controller 1911c.

[0051] As 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 14 (see Figure 1211). Figure 4) and the battery upper cover 1211 is used to fit the seat 14 to cover the sub-frame 112 in the height direction. The electric appliance system 19 further comprises an NFC (Near Field Communication) card reader 196 installed on the battery upper cover 1211, at least part of the NFC card reader 196 passes through the battery upper cover 1211 and extends to the space below the battery upper cover 1211. The NFC card reader 196 is equipped with an NFC key, and the NFC key is inserted into the NFC card reader 196 to cooperate with the NFC card reader 196 and the NFC key to control the start of the electric all-terrain vehicle 100.

[0055] The NFC card reader 196 is set as a card insertion type card reader, the NFC card reader 196 is installed on the battery upper cover 1211, and the NFC key is inserted into the card insertion type card reader to control the start of the electric all-terrain vehicle 100. Through the above setting, the distance between the NFC key and the NFC card reader 196 is reduced, the card reading sensitivity of the NFC card reader 196 is increased, the convenience of the driver using the NFC key is improved, and the risk of losing the key is reduced.

[0056] Specifically, at least part of the battery upper cover 1211 is recessed towards the sub-frame 112 to form a slope towards the upper rear, at least part of the NFC card reader 196 passes through the slope, and the battery upper cover 1211 has a drain hole 1211a passing through the opposite two surfaces thereof, the drain hole 1211a is arranged below the slope. Exemplarily, when it rains, rainwater enters the NFC card reader 196, the rainwater can move to the drain hole 1211a along the slope and be drained through the drain hole 1211a. Through the above setting, the waterproofness of the NFC card reader 196 is increased, and the durability of the NFC card reader 196 is further increased.

[0057] As shown in FIG. 1, Figure 8 As an optional implementation, the NFC card reader 196 comprises a shell 1961 and a rubber piece 1962, the shell 1961 surrounds a card reading space, and the rubber piece 1962 is arranged on the inner wall of the shell 1961 and surrounds at least part of the card reading space. Among them, the card reading space is used for at least part of the NFC key to stay inside the NFC card reader 196, and the rubber piece 1962 is used to reduce the risk of damage caused by the collision between the NFC key and the shell 1961 due to bumps during the driving of the electric all-terrain vehicle 100.

[0058] Specifically, the NFC card reader 196 further comprises a PCB board 1963 (Printed Circuit Board) on which an NFC key comprises an NFC chip. An NFC antenna is arranged on the PCB board 1963, and is used to detect the NFC key inserted into the NFC card 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 card reader 196 is fixed, and the PCB board 1963 is subjected to potting treatment to improve the dustproof and waterproof performance of the PCB board 1963 and the stability of NFC key detection.

[0059] Further, a notch is formed on the shell 1961 to communicate the card reading space and the front space 1511 of the cargo compartment, and the NFC card reader 196 further comprises an elastic member 1964 arranged at the notch. The elastic member 1964 is connected to the shell 1961 by fasteners. When the NFC key adapted to the NFC card reader 196 is inserted into the card reading space, the elastic member 1964 abuts against the NFC key in a direction perpendicular to the insertion direction of the NFC key to limit the movement of the NFC key in the card reading space in the direction perpendicular to the insertion direction of the NFC key. The size of the notch is approximately equal to the size of a human finger, so as to facilitate the driver to take the NFC key.

[0060] Exemplarily, the elastic member 1964 is a spring sheet, and the side of the spring sheet away from the notch is connected to the shell 1961 by two screws. When the spring sheet needs to be replaced, only two screws need to be disassembled to achieve replacement.

[0061] The above-mentioned elastic member 1964 is easy to replace, so as to limit the NFC key in the card reading space in the direction perpendicular to the insertion direction of the NFC key and reduce the risk of the NFC key being separated from the NFC card reader 196 in the case that the NFC key is not taken out by the rider.

[0062] As an optional implementation manner, the elastic member 1964 comprises an anti-wear plastic member installed at the end of the elastic member 1964 abutting against the NFC key. The anti-wear plastic member is used to prevent metal friction between the NFC key and the elastic member 1964 after the NFC key is inserted into the card reading space, so as to protect the appearance of the NFC key and improve the durability of the NFC card reader 196 and the NFC key.

[0063] It should be noted that the NFC chip can be learned by other mobile terminals, and the driver can use the mobile terminal learning the NFC chip to start the vehicle instead of using the NFC key, so as to start the vehicle more simply.

[0064] Exemplarily, when the driver needs to start the electric all-terrain vehicle 100, the NFC key is inserted into the NFC card reader 196 through the gap on the shell 1961, so that the NFC key abuts against the wear-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. And during the driving of the electric all-terrain vehicle 100, the elastic part 1964 keeps the NFC key in the card reading space at all times, reducing the risk of dropping the NFC key.

[0065] As shown in Figure 9 As an implementation form, the electric appliance system 19 further includes a lighting assembly 1919, and the lighting assembly 1919 includes a headlamp 1919a installed on the front fender 1212. The front fender 1212 has a first storage groove 1212b recessed downward of the electric all-terrain vehicle 100, and the front shelf cover 1213 has a front shelf storage opening 1213b penetrating through opposite surfaces thereof, and the opening of the first storage groove 1212b coincides with the front shelf storage opening 1213b in the height direction. Thus, the front shelf cover 1213 has a deeper storage space, improves the storage capacity of the front shelf cover 1213, and further increases the storage space of the electric all-terrain vehicle 100.

[0066] As an implementation form, a reference plane 104 perpendicular to the height direction is defined, the orthographic projection of the front shelf storage opening 1213b on the reference plane 104 is defined as a storage groove projection, and the orthographic projection of the front shelf cover 1213 on the reference plane 104 is defined as a shelf projection. The ratio of the storage groove projection to the shelf projection ranges from 0.2 to 0.3. Further, the ratio of the storage groove projection to the shelf projection ranges from 0.23 to 0.27. More preferably, the ratio of the storage groove projection to the shelf projection is 0.25. It should be noted that if the ratio of the storage groove projection to the shelf projection is too small, the first storage groove 1212b has less internal space to place objects, and objects with large sizes cannot be placed in the first storage groove 1212b. If the ratio of the storage groove projection to the shelf projection is too large, the first storage groove 1212b will affect the arrangement of other components.

[0067] As an implementation form, the first storage groove 1212b overlaps the headlamp 1919a from the height direction, and the first storage groove 1212b is located above the headlamp 1919a.

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

[0069] AsFigure 10 As an implementation form, the depth range D8 of the front storage space extending in the height direction is 100mm to 140mm, as shown in the figure, the front storage space is composed of the first storage groove 1212b and the front shelf storage opening 1213b. 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 storage effect of the front storage space is poor, and the storage demand of the driver and passenger cannot be met. If the depth range D8 is too large, the bottom of the first storage groove 1212b will contact the headlamp 1919a, affecting the arrangement of the headlamp 1919a.

[0070] As an implementation form, the ratio of the depth D9 of the first storage groove 1212b to the depth D10 of the front shelf storage opening 1213b is 1.1 to 1.7. Further, the ratio range is 1.21 to 1.53. More preferably, the ratio is 1.43. Through the above setting, in the case of determining the depth of the front storage space, the depth of the first storage groove 1212b and the depth of the front shelf storage opening 1213b are more reasonably distributed, and the storage capacity of the first storage groove 1212b is improved.

[0071] Further, the front shelf cover 1213 is provided with a plurality of fixing parts distributed around the outer edge of the front shelf storage opening 1213b, and the plurality of fixing parts are used to fix the storage accessory, so that the front shelf storage opening 1213b can be covered by the storage accessory.

[0072] For example, the storage accessory is set as a storage cover plate or a mesh bag, and the storage cover plate or the mesh bag is detachably connected with the front shelf cover 1213 through a buckle structure.

[0073] As an implementation form, at least part of the rear frame 1113 is arranged behind the subframe 112. The rear fender 1231 has a second storage groove 1231b (see Figure 9 ) recessed downward of the electric all-terrain vehicle 100. The rear cover 123 further includes a rear shelf cover 1232, which is arranged on the rear fender 1231, and the rear shelf cover 1232 has a rear shelf storage opening 1232b penetrating through the opposite two surfaces thereof, and the opening of the second storage groove 1231b coincides with the rear shelf storage opening 1232b in the height direction, thereby improving the storage capacity of the rear shelf cover 1232.

[0074] The lighting assembly 1919 further includes a tail lamp 1919b mounted on the rear fender 1231. In the height direction, the second storage groove 1231b overlaps the tail lamp 1919b, and the second storage groove 1231b is located above the tail lamp 1919b.

[0075] The rear shelf cover 1232 has a plurality of fixing portions distributed around the outer edge of the rear shelf storage opening 1232b, and the fixing portions are used to connect the storage accessory matched with the rear shelf cover 1232, and the rear shelf storage opening 1232b can be covered by the storage accessory.

[0076] Exemplarily, the storage accessory is provided as a cover net, the cover net is bound to the plurality of fixing portions distributed around the outer edge of the rear shelf storage opening 1232b, and the cover net is at least partially located below the rear shelf storage opening 1232b when viewed in the length direction, so as to prevent the articles in the second storage tank 1231b from jumping out of the second storage tank 1231b due to bumping during the driving of the electric all-terrain vehicle 100.

[0077] As shown in Figure 11 and Figure 12 As an implementation manner, the front cover 121 includes a front apron 1217, the front apron 1217 is connected with the front fender 1212 and is arranged between the front fender 1212 and the seat 14, and the front apron 1217 is distributed on the left and right sides of the seat 14; the front apron 1217 has an opening penetrating through the opposite two end faces, and the front apron 1217 is provided with an interface cover plate 1217a for closing the opening of the front apron 1217, and the interface cover plate 1217a has two states of opening and closing. The front cover 121 further includes an inner fender 1218, the inner fender 1218 is connected with the front fender 1212 and / or the inner fender 1218 is connected with the front apron 1217, and the inner fender 1218 is located between the front wheel and the front apron 1217, so that the interface mounting space 105 is formed between the inner fender 1218 and the front apron 1217, and the interface mounting space 105 is communicated with the outside through the opening of the front apron 1217. The electric system 19 further includes a battery charging interface 197 for connecting a charging gun, the battery charging interface 197 is electrically connected with the power battery 18, and the battery charging interface 197 is arranged in the interface mounting space 105.

[0078] Exemplarily, when the driver needs to use the battery charging interface 197, the battery charging interface 197 hidden in the interface mounting space 105 can be exposed for the driver to use by opening the interface cover plate 1217a located on the front apron 1217.

[0079] In the embodiment of the present application, the front fender 1217 and the inner fender 1218 are arranged between the front fender 1212 and the seat 14, so that the front fender 1217 and the inner fender 1218 form an interface mounting space 105, and the battery charging interface 197 is arranged in the interface mounting space 105, so as to avoid the battery charging interface 197 from being exposed. Meanwhile, the front fender 1217 has an opening and is provided with an interface cover plate 1217a for closing the opening of the front fender 1217. When the driver uses the battery charging interface 197, the interface cover plate 1217a is opened, and the battery charging interface 197 can be directly used. Through the above arrangement, the durability of the battery charging interface 197 is improved, the risk of water entering the battery charging interface 197 is reduced, and the convenience of charging is increased.

[0080] As shown in Figure 12 As an implementation manner, at least part of the front fender 1217 extends to the lower rear of the electric all-terrain vehicle 100. When the battery charging interface 197 is arranged in the interface mounting space 105, the interface direction of the battery charging interface 197 is substantially perpendicular to the extension direction of the front fender 1217, so that the interface direction of the battery charging interface 197 and the reference plane 104 have an inclination angle θ. A reference straight line 106 is defined, and the direction of the reference straight line 106 is parallel to the interface direction of the battery charging interface 197. The angle between the reference straight line 106 and the horizontal plane reference plane 104 is the inclination angle θ described above. The range of the inclination angle θ is 30° to 50°. Further, the range of the inclination angle θ between the interface direction of the battery charging interface 197 and the reference plane 104 is 32° to 48°. More preferably, the range of the inclination angle θ between the interface direction of the battery charging interface 197 and the reference plane 104 is 35° to 45°. It should be noted that if the inclination 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 to insert a charging cable such as a data cable into the battery charging interface 197 when using the battery charging interface 197, and the comfort of human-computer interaction of the electric all-terrain vehicle 100 is reduced.

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

By pressing the interface cover plate 1217a, the locking mechanism can lock the interface cover plate 1217a to close the opening of the front baffle 1217, or release the locking mechanism and pop the interface cover plate 1217a open, so that the interface cover plate 1217a can rotate relative to the front baffle 1217 along the circumference of the rotating shaft to open the opening of the front baffle 1217.

[0086] By the above arrangement, the battery charging interface 197 is fixed to the interface fixing panel 1219 installed on the front baffle 1217, so that the battery charging interface 197 is fixed in the interface installation space 105, avoiding the battery charging interface 197 from shaking in the interface installation space 105, and unable to insert the charging harness into the battery charging interface 197, resulting in difficulty in using the battery charging interface 197. At the same time, the interface cover plate 1217a is connected to the front baffle 1217 or the interface fixing panel 1219 through a rotating shaft, so as to control the opening or closing of the opening of the front baffle 1217 by opening or closing the interface cover plate 1217a, thereby enhancing the protection of the battery charging interface 197 and improving the convenience of using the battery charging interface 197.
