[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 and Figure 2 , the battery compartment assembly 100 of the embodiment of the present invention is applied to an electric motorcycle or an electric bicycle, and includes a housing 10, a rotating member 50, and a locking device 70. The housing 10 is a hollow structure with an opening 11 at one end, and a receiving cavity 30 is formed in the hollow part. The receiving cavity 30 is used to receive the battery 101 of the electric motorcycle or the electric bicycle. One end of the rotating member 50 is rotatably installed on the housing 10, and the other end is installed on the electric motorcycle or the electric bicycle. The battery compartment assembly 100 can rotate around the rotating member 50, so that the opening 11 of the housing 10 faces the first direction (as shown by the arrow A in Figure 2 ), which is convenient for replacing the battery. The locking device 70 includes a first locking member 71 and a second locking member 73. The first locking member 71 is arranged on the housing 10, and the second locking member 73 is arranged on the electric motorcycle or the electric bicycle. When the first locking member 71 and the second locking member 73 are locked, the battery compartment assembly 100 can be prevented from rotating. After the locking device 70 is opened, the battery compartment assembly 100 can rotate around the rotating member 50.

[0025] In the battery compartment assembly 100 of the present invention, the rotating member 50 is arranged on the housing 10, and the housing 10 is rotatably installed on the rotating member 50. After the locking device 70 is opened, the housing 10 rotates around the rotating member 50, so that the opening 11 faces the first direction (upward), which is convenient for the user to replace the battery 101 and shortens the time for replacing the battery 101.

[0026] Please refer to Figure 2 and Figure 3 , in some embodiments, the rotating member 50 is a rotating shaft. One end of the rotating shaft is rotatably installed on the housing 10, and the other end is installed on the electric motorcycle or the electric bicycle. After the locking device 70 is opened, the battery compartment assembly 100 rotates around the rotating shaft, so that the opening 11 of the receiving cavity 30 faces upward, which is convenient for replacing the battery 101. For the rotation direction of the battery compartment assembly 100, please refer to Figure 2In the direction of arrow B. In some embodiments, the distance from the rotating member 50 to the opening 11 is less than the distance from the rotating member 50 to the surface of the housing 10 opposite to the opening 11. In this way, when the locking device 70 is opened, due to the action of gravity, the battery compartment assembly 100 automatically rotates around the rotation axis, with the opening 11 facing the first direction, making it more convenient to use. In other embodiments, the rotating member 50 can also be a device that can drive the battery compartment assembly 100 to rotate after the other locking device 70 is unlocked. More specifically, the distance from the rotating member 50 to the opening 11 is half to two-thirds of the distance from the rotating member 50 to the surface of the housing 10 opposite to the opening 11, which is more convenient for the disassembly and assembly of the battery 101.

[0027] In some embodiments, the locking device 70 can be a snap structure, with a part of the snap structure mounted on the housing 10 and the other part mounted on the electric motorcycle or electric bicycle. Specifically, the first locking member 71 can be a hook or a clamping portion, and the second locking member 73 can be a clamping portion or a hook. When the first locking member 71 is a hook, the second locking member 73 is a clamping portion, and the hook and the clamping portion are buckled with each other to form a snap structure. On the contrary, when the first locking member 71 is a clamping portion, the second locking member 73 is a hook.

[0028] Please refer to Figure 1 , in another embodiment, the locking device 70 can also be a lock, with a part of the lock fixed on the electric motorcycle or electric bicycle and the other part fixed on the housing 10, and the two parts are locked to lock the battery compartment assembly 100. When the locking device 70 is a lock, the lock can be an electronic lock or a mechanical lock, and the present invention does not make specific limitations on this.

[0029] Please refer to Figure 1 , the battery compartment assembly 100 of the embodiment of the present invention further includes a deceleration device 90, and the deceleration device 90 is mounted on the rotating member 50 and is used to slow down the rotation speed of the battery compartment assembly 100 around the rotating member 50 when the locking device 70 is opened, so as to prevent the battery compartment assembly 100 from rotating too fast under the action of gravity, hitting the body of the electric motorcycle or electric bicycle, making a loud noise, or even damaging the body of the electric motorcycle or electric bicycle after a long time.

[0030] Please refer to Figure 4, in some embodiments, the deceleration device 90 is a damper. More specifically, the deceleration device 90 is a rotary damper, which can be a unidirectional rotary damper or a bidirectional rotary damper. The present invention does not make specific limitations thereto. In some embodiments, the deceleration device 90 is provided with a mounting hole 93 and a positioning hole 95. The mounting hole 93 is used to rotatably sleeved the deceleration device 90 on the rotating shaft of the rotating member 50. The positioning hole 95 is used to cooperate with a positioning member to fix the deceleration device 90 on an electric motorcycle or an electric bicycle. Specifically, the positioning member can be a screw or a screw and nut. In some embodiments, the positioning hole 95 can be 1, 2, 3, 4 or more. When there are at least two mounting holes 95, the deceleration device 90 can be better fixed.

[0031] Please refer to Figure 5 and Figure 6 , the present invention provides an electric vehicle 200, which is an electric motorcycle or an electric bicycle, and includes an electric vehicle body 210 and the battery compartment assembly 100 of the above embodiments of the present invention. The battery compartment assembly 100 is rotatably mounted at the footrest position of the electric vehicle body 210. Figure 5 is a schematic structural diagram of the battery compartment assembly 100 locked on the electric vehicle body 210, Figure 6 is a schematic structural diagram with the opening 11 facing upward after the battery compartment assembly 100 is unlocked and rotated around the rotating member 50.

[0032] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
