[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation modes of the present invention.

[0027] like Figures 1 to 4 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a body cover 12, a travel assembly 13, a power assembly 14, a power battery 15, a transmission assembly 16, a seat assembly 17 and a cargo box assembly 18. The frame 11 is used as the basic framework of the all-terrain vehicle 100 to carry the body cover 12, the travel assembly 13, the power assembly 14, the power battery 15, the transmission assembly 16, the seat assembly 17 and the cargo box assembly 18. Among them, the body cover 12 is at least partially arranged on the frame 11, and the body cover 12 and the frame 11 are connected to form a protective frame for protecting the internal parts of the all-terrain vehicle 100. The travel assembly 13 is at least partially arranged under the frame 11, and the travel assembly 13 includes a front wheel 131 and a rear wheel 132. The power assembly 14 is supported by the frame 11, and the power assembly 14 is connected to at least one of the front wheel 131 and the rear wheel 132 through the transmission assembly 16, so that the power assembly 14 can drive the all-terrain vehicle 100 to move. The power battery 15 is at least partially disposed on the frame 11, and the power battery 15 can also provide energy for the power assembly 14. The seat assembly 17 is at least partially disposed on the frame 11, and is used to provide support for the driver and the passenger. The cargo box assembly 18 is at least partially disposed on the rear side of the frame 11, and the cargo box assembly 18 is used to carry cargo on the all-terrain vehicle 100. Specifically, the frame 11 includes a rear frame 111 disposed at the rear of the frame 11, and the rear frame 111 is surrounded by a receiving space 1111, and the power assembly 14 is at least partially disposed in the receiving space 1111. In order to clearly illustrate the technical solution of the present invention, the following is also defined. Figure 1In the present application, the front-to-back direction of the all-terrain vehicle 100 refers to the length direction of the all-terrain vehicle 100, the left-to-right direction of the all-terrain vehicle 100 refers to the width direction of the all-terrain vehicle 100, and the up-down direction of the all-terrain vehicle 100 refers to the height direction of the all-terrain vehicle 100.

[0028] As an implementation method, the power assembly 14 includes a drive motor 141 and a range extender 142. The range extender 142 provides energy for the drive motor 141, and the drive motor 141 is used to drive the travel assembly 13. The power battery 15 is electrically connected to the range extender 142 so that the range extender 142 can charge the power battery 15; the power battery 15 is also electrically connected to the drive motor 141 so that the power battery 15 can provide energy for the drive motor 141.

[0029] like Figure 5 and Figure 6 As shown, as an implementation, the seat assembly 17 includes a rear seat 172 disposed near the power assembly 14, and the rear seat 172 is at least partially disposed on the frame 11 to provide support for passengers. The rear seat 172 includes a backrest 1721 and a seat cushion 1722 at least partially connected to the backrest 1721, and the backrest 1721 includes an upper backrest 1721a, an upper frame 1721c, and a lower backrest 1721b. Specifically, the lower backrest 1721b is connected to the seat cushion 1722, and the seat cushion 1722 is detachably connected to the frame 11. More specifically, the lower backrest 1721b can be integrally formed with the seat cushion 1722, so that the lower backrest 1721b can be detachably connected to the frame 11 through the seat cushion 1722. The upper backrest 1721a is rotatably connected to the frame 11. More specifically, the upper frame 1721c is disposed on the upper backrest 1721a, and the upper backrest 1721a is rotatably connected to the frame 11 via the upper frame 1721c.

[0030] As another implementation, the backrest 1721 may also include a lower frame 1721d fixedly connected to the frame 11, and the lower frame 1721d is arranged on the lower backrest 1721b. In this case, the lower backrest 1721b and the seat cushion 1722 are independently arranged, specifically, the lower backrest 1721b and the lower frame 1721d are detachably connected, and the seat cushion 1722 and the frame 11 are detachably connected. Among them, the upper backrest 1721a and the lower frame 1721d are rotatably connected, that is, the upper backrest 1721a is not rotatably connected to the frame 11. More specifically, the upper backrest 1721a is rotatably connected to the lower frame 1721d through the upper frame 1721c arranged on the upper backrest 1721a.

[0031] Through the above two arrangements, the lower backrest 1721b and the seat cushion 1722 can be easily disassembled or installed. At the same time, after the lower backrest 1721b and the seat cushion 1722 are disassembled, an inspection port 1721e can be formed, so that the parts of the all-terrain vehicle 100 located at the rear side of the lower backrest 1721b and at the lower side of the seat cushion 1722 can be inspected through the inspection port 1721e, thereby reducing the maintenance cost of the all-terrain vehicle 100 and improving the maintainability of the all-terrain vehicle 100. Specifically, the lower backrest 1721b is covered on the inspection port 1721e along the length direction of the all-terrain vehicle 100, and the related parts behind the lower backrest 1721b can be inspected through the inspection port 1721e, wherein, when viewed along the length direction of the all-terrain vehicle 100, the inspection port 1721e and the lower backrest 1721b are substantially overlapped.

[0032] Among them, the frame 11 is provided with a first connector 114 and a first clip connector 115, and the bottom of the seat cushion 1722 is provided with a second connector (not shown) and a second clip connector (not shown). The first connector 114 and the second connector are plugged into each other, and the first clip connector 115 and the second clip connector are clipped into each other to realize a detachable connection between the frame 11 and the seat cushion 1722, thereby improving the disassembly and assembly efficiency of the seat cushion 1722, thereby facilitating the maintenance of components such as the generator controller 224 on the lower side of the seat cushion 1722.

[0033] Furthermore, the rearmost end of the seat cushion 1722 is embedded in the first clamping member 115. Optionally, the first clamping member 115 surrounds to form a slot for the seat cushion 1722 to be embedded, and the first clamping member 115 at least partially extends along the width direction of the all-terrain vehicle 100. When the seat cushion 1722 is embedded in the slot, the seat cushion 1722 can rotate around the first clamping member 115.

[0034] Furthermore, the first connector 114 is a pin extending basically in the height direction, and the bottom surface of the seat cushion 1722 has a socket that can cooperate with the first connector 114, that is, the second connector can be set as a socket, and when the seat cushion 1722 is connected to the mid-frame 112, the pin is at least partially set in the socket.

[0035] Through the above arrangement, the convenience of disassembling the seat cushion 1722 is improved, thereby reducing the difficulty of repairing and replacing the generator controller 224.

[0036] A transverse plane 103 (see Figure 1), the projection of the lower backrest 1721b on the transverse plane 103 along the length direction of the all-terrain vehicle 100 is a first projection surface, the projection of the backrest 1721 on the transverse plane 103 along the length direction of the all-terrain vehicle 100 is a second projection surface, and the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 0.29 and less than or equal to 0.56. Specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 0.36 and less than or equal to 0.49. More specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface can also be 0.43. Through the above-mentioned arrangement, it is possible to avoid the operating space of the inspection opening 1721e formed after the lower backrest 1721b is disassembled being too small, thereby facilitating the inspection of the all-terrain vehicle 100 components located at the rear side of the lower backrest 1721b and at the lower side of the seat cushion 1722, thereby reducing the maintenance cost of the all-terrain vehicle 100; it is also possible to avoid the operating space of the inspection opening 1721e formed after the lower backrest 1721b is disassembled being too large and occupying additional layout space, thereby improving the space utilization of the all-terrain vehicle 100 and improving the structural compactness of the rear seat 172.

[0037] In this embodiment, the range extender 142 is arranged behind the lower backrest 1721b, and when viewed along the length direction of the all-terrain vehicle 100, the lower backrest 1721b and the range extender 142 at least partially overlap. Further, a transverse plane 103 perpendicular to the length direction of the all-terrain vehicle 100 is defined, and the projection of the lower backrest 1721b along the length direction of the all-terrain vehicle 100 on the transverse plane 103 is defined as a first projection, and the projection of the range extender 142 along the length direction of the all-terrain vehicle 100 on the transverse plane 103 is defined as a second projection, wherein the first projection and the second projection at least partially overlap. The area of ​​the overlapping portion of the first projection and the second projection is set to be greater than or equal to 627cm 2 And less than or equal to 941cm 2 Furthermore, the area of ​​the overlapped portion of the first projection and the second projection is set to be greater than or equal to 705 cm 2 And less than or equal to 863cm 2 More preferably, the area of ​​the overlap between the first projection and the second projection is set to 784 cm 2 It should be noted that if the area of ​​the overlapped portion of the first projection and the second projection is too small, when the height of the rear seat 172 remains unchanged, the lower backrest 1721b will be disassembled, resulting in the inspection port 1721e being too small for operation, which is not conducive to the inspection and maintenance of the range extender 142. The above arrangement improves the maintenance convenience of the all-terrain vehicle 100.

[0038] In this embodiment, the all-terrain vehicle 100 further includes an air intake assembly 19, which includes an air filter mechanism 191 disposed on the power assembly 14, and the air filter mechanism 191 is disposed on the rear side of the rear seat 172, and is used to deliver air to the power assembly 14. Specifically, the air filter mechanism 191 is at least partially disposed on the front side of the range extender 142, and the air filter mechanism 191 is also close to the position of the lower backrest 1721b, and the air filter mechanism 191 is connected to the range extender 142. Among them, when viewed from the length direction of the all-terrain vehicle 100, the air filter mechanism 191 and the lower backrest 1721b at least partially overlap. Specifically, the lower frame 1721d is provided with an inspection port 1721e, and when viewed from the length direction of the all-terrain vehicle 100, the inspection port 1721e and the air filter mechanism 191 at least partially overlap. Since the air filter mechanism 191 needs to filter the air entering the range extender 142, dust is easily accumulated to cause blockage, thereby affecting the normal operation of the air filter mechanism 191, so it is necessary to inspect and maintain the air filter mechanism 191. Through the above arrangement, the air filter mechanism 191 located at the rear side of the lower backrest 1721b can be inspected through the inspection port 1721e, thereby reducing the maintenance cost of the all-terrain vehicle 100.

[0039] Optionally, in order to realize the loading and unloading between the lower backrest 1721b and the lower frame 1721d, and to facilitate the inspection and maintenance of the range extender 142 and the air filter mechanism 191, a clamping piece is provided on the lower backrest 1721b, and the clamping piece is provided on the rear end surface of the lower backrest 1721b, and the clamping piece is used to connect the lower frame 1721d. The connection between the clamping piece and the lower frame 1721d can be through interlocking and rotation, etc., so as to facilitate the rapid disassembly or installation between the lower backrest 1721b and the lower frame 1721d. Through the above arrangement, the inspection and maintenance of the range extender 142 and the air filter mechanism 191 are facilitated, and the maintenance convenience of the all-terrain vehicle 100 is improved.

[0040] As an implementation method, the height of the upper backrest 1721a extending in the height direction of the all-terrain vehicle 100 is defined as a first height H4, and the height of the lower backrest 1721b extending in the height direction of the all-terrain vehicle 100 is defined as a second height H5. The ratio between the first height H4 and the second height H5 is greater than or equal to 1.8 and less than or equal to 2.6. Furthermore, the ratio between the first height H4 and the second height H5 is greater than or equal to 2 and less than or equal to 2.4. More preferably, the ratio between the first height H4 and the second height H5 can also be 2.2. If the ratio between the first height H4 and the second height H5 is too large, the height of the lower backrest 1721b is too small. After the lower backrest 1721b is disassembled, the space of the inspection port 1721e is small, which is not conducive to maintenance personnel to maintain the air filter mechanism 191 or the range extender 142 through the inspection port 1721e. If the ratio between the first height H4 and the second height H5 is too small, the height of the lower backrest 1721b is too large, and when the upper backrest 1721a is rotated to the second state, the cargo carrying capacity of the all-terrain vehicle 100 cannot be improved. Through the above arrangement, the maintenance convenience of the all-terrain vehicle 100 is improved while ensuring the cargo carrying capacity of the cargo box assembly 18.

[0041] Optionally, the seat cushion 1722 is arranged below the lower backrest 1721b, and the seat cushion 1722 and the frame 11 are arranged to be detachably connected. Optionally, the seat cushion 1722 can be arranged to be fixedly connected or integrally formed with the lower backrest 1721b. The all-terrain vehicle 100 also includes a power battery 15 and a generator controller 224, wherein the power battery 15 is connected to the generator controller 224, wherein the generator controller 224 is arranged below the seat cushion 1722, and the generator controller 224 is arranged between the power battery 15 and the range extender 142. When observed along the height direction of the all-terrain vehicle 100, the seat cushion 1722 and the generator controller 224 at least partially overlap. Through the above arrangement, when the seat cushion 1722 is disassembled, the generator controller 224 can be inspected and repaired, thereby improving the maintenance convenience of the all-terrain vehicle 100.

[0042] Furthermore, the lower backrest 1721b and the upper backrest 1721a are arranged to be in surface contact, and form a contact surface that basically extends toward the upper front of the all-terrain vehicle 100. A reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, and the angle Ω between the contact surface and the reference plane 101 is set to be greater than or equal to 0° and less than or equal to 90°. Specifically, the angle Ω between the contact surface and the reference plane 101 is set to be greater than or equal to 10° and less than or equal to 80°. Preferably, the angle Ω between the contact surface and the reference plane 101 is set to be greater than or equal to 20° and less than or equal to 70°. Through the above arrangement, during the loading and unloading process of the lower backrest 1721b, interference between the lower backrest 1721b and the upper backrest 1721a can be avoided, thereby improving the assemblability of the lower backrest 1721b.

[0043] like Figure 7 , Figure 8 and Fig. 9 As shown, as an implementation, the upper backrest 1721a includes a first state for seating and a second state for loading cargo. When the upper backrest 1721a is in the first state, the rear side surface of the upper backrest 1721a and the rear side surface of the lower backrest 1721b extend in substantially the same direction, so that the upper backrest 1721a and the lower backrest 1721b cooperate to support the back of the passenger, thereby improving the comfort of the rear seat 172. When the upper backrest 1721a is in the second state, the rear side surface of the upper backrest 1721a and the cargo surface of the cargo box assembly 18 are substantially parallel, so that the upper backrest 1721a can cooperate with the cargo surface of the cargo box assembly 18 in the second state to lengthen the cargo length of the cargo box assembly 18, thereby increasing the cargo space of the all-terrain vehicle 100. Through the above configuration, the upper backrest 1721a can be used in two ways, so that the upper backrest 1721a integrates cargo carrying and supporting functions, which is conducive to improving the functional diversity of the upper backrest 1721a, and further improving the practicality of the all-terrain vehicle 100. In addition, through the two different usage modes of the upper backrest 1721a, different usage requirements of the all-terrain vehicle 100 can be met under different working conditions, so that without adding additional parts, the riding requirements of the seat assembly 17 and the cargo carrying requirements of the all-terrain vehicle 100 are met at the same time, thereby improving the compactness of the structure of the all-terrain vehicle 100 and increasing the cargo carrying space of the all-terrain vehicle 100 to meet different cargo carrying requirements. Among them, when the upper backrest 1721a is in the second state, the rear side surface of the upper backrest 1721a and the cargo surface of the cargo box assembly 18 are basically at the same height along the height direction of the all-terrain vehicle 100, that is, along the height direction of the all-terrain vehicle 100, the cargo surface of the cargo box assembly 18 is higher than the uppermost end of the lower backrest 1721b, which is conducive to the rear side surface of the upper backrest 1721a and the cargo surface of the cargo box assembly 18 to cooperate to form a cargo space for loading cargo.

[0044] When the upper frame 1721c and the lower frame 1721d are rotatably connected, that is, the seat cushion 1722 and the lower backrest 1721b are independently arranged, the rear seat 172 further includes a pivot shaft 1723, and the upper frame 1721c and the lower frame 1721d are rotatably connected through the pivot shaft 1723, and the minimum distance D4 between the axis of the pivot shaft 1723 and the cargo surface of the cargo box assembly 18 is set to be greater than or equal to 66 mm and less than or equal to 125 mm. Specifically, the minimum distance D4 between the axis of the pivot shaft 1723 and the cargo surface of the cargo box assembly 18 is set to be greater than or equal to 81 mm and less than or equal to 110 mm. More specifically, the minimum distance D4 between the axis of the pivot shaft 1723 and the cargo surface of the cargo box assembly 18 can also be set to 95.2 mm. Through the above arrangement, the upper backrest 1721a can be prevented from interfering with the cargo box assembly 18 during the rotation process around the pivot shaft 1723, so as to improve the working stability of the cargo box assembly 18 and the upper backrest 1721a. In this embodiment, the rear seat 172 also includes a connecting plate 1724, which is rotatably connected to the upper frame 1721c or the upper backrest 1721a. A preset plane 1724a is defined, and the connecting plate 1724 basically extends along the preset plane 1724a. Among them, the connecting plate 1724 includes a storage state and a working state. When the connecting plate 1724 is in the storage state, the extension direction of the preset plane 1724a and the rear side of the lower backrest 1721b is basically consistent. When the connecting plate 1724 is in the working state, the preset plane 1724a and the cargo surface of the cargo box assembly 18 are basically parallel. At this time, one end of the connecting plate 1724 is rotatably connected to the upper frame 1721c or the upper backrest 1721a, and the other end of the connecting plate 1724 overlaps the cargo surface of the cargo box assembly 18, so that the connecting plate 1724 can fill the gap between the pivot shaft 1723 and the cargo surface of the cargo box assembly 18 when in the working state, preventing the cargo from falling from the gap between the pivot shaft 1723 and the cargo surface of the cargo box assembly 18, thereby improving the cargo loading safety of the all-terrain vehicle 100.

[0045] Specifically, the rotation direction of the upper frame 1721c relative to the lower frame 1721d is the first rotation direction, that is, the rotation direction of the upper backrest 1721a from the first state to the second state is the first rotation direction. The rotation direction of the connecting plate 1724 relative to the upper frame 1721c or the upper backrest 1721a is the second rotation direction, that is, the rotation direction of the connecting plate 1724 from the storage state to the working state is the second rotation direction. The first rotation direction and the second rotation direction are opposite.

[0046] It should be noted that when the upper frame 1721c and the vehicle frame 11 are rotatably connected, that is, when the seat cushion 1722 and the lower backrest 1721b are connected, the cargo box assembly 18 extends toward the rear seat 172 and forms a cargo extension surface 181. When the upper backrest 1721a is in the second state, the cargo extension surface 181 and the rear side surface of the upper backrest 1721a are substantially in contact, so that the structure of the connecting plate 1724 can be omitted, so as to simplify the structure of the rear seat 172, thereby improving the compactness of the rear seat 172 and reducing the production cost of the rear seat 172.

[0047] like Fig. 9 and Fig.10 As shown, as an implementation, the rear seat 172 further includes a connecting structure 1725, and the connecting structure 1725 is arranged on the upper backrest 1721a. The upper backrest 1721a includes a preset position for cooperating with the cargo box assembly 18 to carry cargo. When the upper backrest 1721a is in the preset position, that is, when the upper backrest 1721a is in the second state, the upper backrest 1721a is fixed to the frame 11 through the connecting structure 1725. Specifically, when the upper backrest 1721a rotates to the preset position, the upper backrest 1721a can be connected to the frame 11 through the connecting structure 1725, so that the upper backrest 1721a is always in the preset position, so as to avoid the upper backrest 1721a from carrying too much weight and causing the upper backrest 1721a to continue to rotate, thereby preventing the cargo on the upper backrest 1721a from detaching from the cargo box assembly 18, so as to further improve the working stability of the upper backrest 1721a. Through the above configuration, the cargo space of the cargo box assembly 18 can be expanded, the cargo capacity of the all-terrain vehicle 100 can be improved, and the matching stability of the upper backrest 1721a and the cargo box assembly 18 can be improved. As an optional implementation, the connection structure 1725 can be set as a detachable structure such as a webbing, a hook, a lock, etc.

[0048] More specifically, a storage groove 1721f for accommodating the connection structure 1725 is formed on the rear side of the upper backrest 1721a. When the connection structure 1725 is in a non-working state, the connection structure 1725 is at least partially disposed in the storage groove 1721f, thereby preventing the connection structure 1725 from interfering with other components of the seat assembly 17 and improving the protection of the connection structure 1725, thereby improving the service life of the connection structure 1725. In addition, through the above arrangement, the space utilization and structural compactness of the rear backrest 1721 can also be improved.

[0049] It should be noted that when the upper frame 1721c or the upper backrest 1721a is provided with a connecting plate 1724, when the connecting plate 1724 is in a storage state and the connecting structure 1725 is in a non-working state, the connecting plate 1724 at least partially covers the connecting structure 1725 to keep the connecting structure 1725 fixed.

[0050] In this embodiment, the vehicle frame 11 includes an armrest frame 113 disposed at the front side of the rear seat 172, and when the upper backrest 1721a is in a preset position, the upper backrest 1721a is fixed to the armrest frame 113 through a connecting structure 1725. Specifically, when the upper backrest 1721a is in the preset position, one end of the connecting structure 1725 is connected to the upper backrest 1721a, and the other end of the connecting structure 1725 is provided with a connecting piece 1725a, and the armrest frame 113 is provided with a fixing piece 1131 that cooperates with the connecting piece 1725a and is fixed, so that the connecting structure 1725 can be prevented from sliding on the armrest frame 113, thereby improving the connection stability between the connecting structure 1725 and the armrest frame 113.

[0051] Furthermore, an anti-slip structure 1132 is also provided on the handrail frame 113. When the fixing member 1131 and the connecting member 1725a are fixed together, the anti-slip structure 1132 at least partially surrounds the connecting member 1725a, thereby preventing the connecting member 1725a from falling off from the fixing member 1131, thereby improving the connection strength between the connecting structure 1725 and the handrail frame 113.

[0052] As an implementation, the rear seat 172 includes a single rear seat 1726 and a multi-person rear seat 1727, which are arranged in a distributed manner along the width direction of the all-terrain vehicle 100. The single rear seat 1726 can be used by a single person, and the multi-person rear seat 1727 can be used by at least two people. Specifically, the single rear seat 1726 and the multi-person rear seat 1727 both include the backrest 1721 and the cushion 1722 to meet different cargo and passenger requirements, thereby improving the functional diversity of the rear seat 172. More specifically, the width of the multi-person seat 1727 extending along the width direction of the all-terrain vehicle 100 is defined as a first width W5, and the width of the single seat 1726 extending along the width direction of the all-terrain vehicle 100 is defined as a second width W6, wherein the first width W5 is set to be greater than the second width W6. The air filter mechanism 191 is arranged behind the multi-person seat 1727. When viewed along the length direction of the all-terrain vehicle 100, the multi-person seat 1727 and the air filter mechanism 191 at least partially overlap. Through the above arrangement, the air filter mechanism 191 can be inspected and repaired through the multi-person seat 1727. In addition, since the width of the multi-person seat 1727 is greater than the width of the single seat 1726, a larger maintenance space can be provided during the inspection and maintenance of the air filter mechanism 191, which is convenient for the inspection and maintenance of the air filter mechanism 191, thereby improving the maintenance convenience of the all-terrain vehicle 100.
