Description

Technical Field

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

[0002] All-terrain vehicles, as outdoor vehicles that combine practicality, entertainment and sports functions, are increasingly popular among consumers. They can travel on various complex road conditions such as beaches, grasslands, and mountain roads.

[0003] All-terrain vehicles (ATVs) include gasoline-powered ATVs and electric ATVs. Electric ATVs are equipped with a charging connector, allowing users to insert a charging gun connected to AC power or a power source into the connector to charge the vehicle. The charging connector typically also features an electronic charging lock, which includes a locking mechanism and an unlocking mechanism. The locking mechanism secures the charging gun during charging to prevent accidental removal, while the unlocking mechanism releases the locking mechanism upon receiving an unlocking command, allowing the charging gun to be removed.

[0004] In related technologies, when a vehicle malfunctions or loses power during charging, the charging electronic lock remains locked, meaning the charging gun is locked and cannot be easily pulled out. In this case, maintenance personnel usually need to remove the side panels and other structures of the vehicle body to complete the mechanical unlocking, which is cumbersome and inconvenient.

For example, combined with numerical description, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0031] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figure 1 and Figure 2 One embodiment of this application provides an electric all-terrain vehicle 100, including a frame 11, a body panel 12, a running system 13, a power system 15, a power battery 16, and a charging system 18. The body panel 12 at least partially covers the frame 11. The running system 13 is at least partially located below the frame 11. The power battery 16 is supported by the frame 11 and electrically connected to the power system 15, providing power to the power system 15. The power system 15 is supported by the frame 11 and is drive-connected to the running system 13. The charging system 18 is used to receive external power and deliver power to the power battery 16.

[0034] In this application, the electric all-terrain vehicle 100 is an electric UTV (Utility Vehicle). The electric all-terrain vehicle 100 also includes a cargo bed 17, which can be used to carry goods. The chassis 11 and the body cover 12 together form the cabin 14, and the cabin 14 is equipped with a seat 141.

[0035] For ease of description, this application defines the directions of front, rear, left, right, up, and down. The front-rear direction refers to the length of the frame 11 of the electric all-terrain vehicle 100, the left-right direction refers to the width of the frame 11, and the up-down direction refers to the height of the frame 11. In this embodiment, the directions of front, rear, left, right, up, and down are based on the state of the electric all-terrain vehicle 100 traveling on a level surface, not on a sloping surface.

[0036] Please see Figure 2 and Figure 3 In one implementation, the frame 11 includes a front frame 111 and a rear frame 112, which are arranged along the length of the frame 11. The front frame 111 is essentially the front of the vehicle, and the rear frame 112 is essentially the body and rear of the vehicle. The passenger compartment 14 is supported by the rear frame 112. Along the length of the frame 11, the power battery 16 is located above the rear frame 112 and is supported by the rear frame 112.

[0037] Please see Figure 2 and Figure 3 In one implementation, the seat 141 is connected to the rear frame 112. Along the height direction of the frame 11, the front part of the power battery 16 is located below the seat 141. This arrangement makes reasonable use of space, helps to reduce the space occupied by the power battery 16, and improves integration and space utilization. The seat 141 includes a seat cushion 1411 and a backrest 1412. The power system 15 is located behind the power battery 16 and below the cargo bed 17, which is located behind the seat 141.

[0038] In one implementation, the charging system 18 includes a charging connector 181 and a charging controller 182. The charging connector 181 is installed on the vehicle body panel 12, specifically on the left or right side panel of the vehicle. The charging connector 181 is electrically connected to the power battery 16 and communicatively connected to the charging controller 182. The charging controller 182 can be a three-in-one controller, which consists of a DC-DC converter, an on-board charger, and a power distribution unit. The on-board charger converts AC to DC power to charge the vehicle. The DC-DC converter converts high-voltage DC power to low-voltage DC power; for example, a DC / DC converter can be used. The power distribution unit is responsible for distributing and managing the high-voltage power.

[0039] Users can charge the power battery 16 via an external charger 183. Specifically, the external charger 183 includes a charging gun 1831, which can be plugged into a charging connector 181 and delivers external power to the power battery 16 through the charging connector 181. The charging controller 182 can control the power delivery to the power battery 16, and performs functions such as high-voltage to low-voltage conversion.

[0040] Please see Figure 4 and Figure 5 As one implementation method, the charging connector 181 is provided with a socket 1814, and the charging gun 1831 (see...) Figure 3 The charging connector 181 includes a housing 1811, a locking member 1812, and an unlocking device 1813. Both the locking member 1812 and the unlocking device 1813 are at least partially located within the housing 1811. The locking member 1812 locks the charging gun 1831, and the unlocking device 1813 is controllable by the charging controller 182 to unlock the locking member 1812. Specifically, the housing 1811 has a locking hole 1811a, and the locking member 1812 can at least partially extend from the locking hole 1811a into the connector 1814 to lock the charging gun 1831. The locking member 1812 may be in the form of a pin. The unlocking device 1813 is controllable by the charging controller 182 to at least retract the locking member 1812 to release the locking of the charging gun 1831. The unlocking device 1813 may be a motor, electric cylinder, or relay with a push rod 1813a. The end of the locking member 1812 is provided with a guide surface 1812a, and the push rod 1813a of the unlocker 1813 can abut against the guide surface 1812a, pushing the locking member 1812 to extend or retract relative to the lock hole 1811a during extension and retraction.

[0041] The charging connector 181 also includes an unlocking switch 1815, part of which is located inside the housing 1811 and part of which is located outside the housing 1811. The unlocking switch 1815 is kinetically connected to the locking member 1812 and can be operated to unlock the locking member 1812. Specifically, since the unlocking switch 1815 is physically connected to the locking member 1812, when the vehicle is powered off or the unlocker 1813 fails, the user can unlock the locking member 1812 by operating the unlocking switch 1815.

[0042] The unlocking switch 1815 is rotatably connected to the housing 1811. The unlocking switch 1815 can, by rotating, at least retract the locking member 1812 to release the locking of the charging gun 1831. In one specific embodiment, the unlocking switch 1815 includes a rotating shaft 1815a, a lever 1815b, and a force-applying member 1815d. The lever 1815b is fixed to one end of the rotating shaft 1815a, and the force-applying member 1815d is fixed to the other end of the rotating shaft 1815a. The force-applying member 1815d can be a cam. The peripheral wall of the locking member 1812 has a mating inclined surface, which can be pushed by the cam to achieve sliding of the locking member 1812. When the rotating shaft 1815a rotates, it can drive the force-applying member 1815d to rotate, and cause the locking member 1812 to extend and retract relative to the lock hole 1811a. In another specific embodiment, the unlocking switch 1815 further includes a pull cord 1815c, or the lever 1815b is replaced by a pull cord 1815c. One end of the pull cord 1815c is connected to one end of the rotating shaft 1815a. By pulling the pull cord 1815c, the rotating shaft 1815a can be rotated.

[0043] In addition, the charging connector 181 is provided with an elastic reset member 1816, which can be a spring. The elastic reset member 1816 is used to drive the locking member 1812 to extend out of the locking hole 1811a to lock the charging gun 1831.

[0044] Please see Figure 6 As one implementation, the electric all-terrain vehicle 100 also includes a housing 19, which has a housing cavity 191. An unlocking switch 1815 is at least partially located within the housing cavity 191. Specifically, both the lever 1815b and the pull rope 1815c are at least partially located within the housing cavity 191. Maintenance personnel can operate the lever 1815b or the pull rope 1815c within the housing cavity 191 to control the unlocking switch 1815 and unlock the vehicle. The housing 19 is partially located behind the seat 141 and in front of the cargo bed 17. The shape of the housing 19 can be approximately L-shaped, with a portion of the housing 19 located below the cargo bed 17.

[0045] Please see Figures 6-8 The accommodating member 19 has at least one opening 192 communicating with the accommodating cavity 191, and a cover plate 193 is used to seal the opening 192. In one embodiment (see...) Figure 7 The opening 192 faces the seat 141, and the seat 141 can be operated to expose the opening 192. Specifically, the opening 192 faces forward, and the opening 192 can be directly behind the backrest 1412 or diagonally behind the backrest 1412. In another embodiment (see...) Figure 8 The opening 192 is positioned facing the hopper 17, and the hopper 17 can be operated to expose the opening 192. Specifically, the opening 192 faces upward and is located below the hopper 17. The opening 192 can be exposed when the hopper 17 is flipped upward.

[0046] Please see Figure 6 The accommodating cavity 191 is provided with a mounting plate 194, which divides the accommodating cavity 191 into two cavities arranged vertically. Optionally, each cavity has a corresponding opening 192. The mounting plate 194 is inclined relative to the horizontal plane, and its front edge is lower than its rear edge.

[0047] Please see Figure 9 and Figure 10 The accommodating cavity 191 is provided with a positioning structure 195. The accommodating cavity 191 is at least used to accommodate the charging gun 1831, and the positioning structure 195 is used to position the charging gun 1831. The positioning structure 195 is fixed to the upper surface of the mounting plate 194. With the above arrangement, the accommodating cavity 192 can be used to accommodate the unlocking switch 1815, the charging gun 1831, and further, an external charger 183. The inclined mounting plate 194 helps the user to retrieve objects from the accommodating cavity 192.

[0048] The positioning structure 195 includes multiple sets of retaining parts 1951, each set of retaining parts 1951 including two spaced-apart retaining parts 1951a, with a slot 1951b formed between the two spaced-apart retaining parts 1951a for at least retaining the charging gun 1831. The external charger 183 also includes a cable 1832 and a charging adapter unit 1833, the cable 1832 connecting the charging gun 1831 and the charging adapter unit 1833. The retaining parts 1951a are not only used for retaining the charging gun 1831, but also for positioning the cable 1832 and the charging adapter unit 1833.

[0049] Please see Figure 9 The portion of the pull cord 1815c located within the accommodating cavity 192 is connected to the side wall of the accommodating cavity 192 along the width direction of the frame 11. This arrangement fully utilizes the space within the accommodating cavity 192, in other words, it facilitates the selection of the pull cord 1815c by maintenance personnel. In another embodiment (not shown), the lever 1815b is at least partially connected to the side wall of the accommodating cavity 192 along the width direction of the frame 11.

[0050] In one embodiment (not shown), the end of the pull rope 1815c away from the pivot 1815a is located below the seat 141. This arrangement also makes it easier for maintenance personnel to find the pull rope 1815c.

[0051] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
