Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

The present application will now be described in further detail with reference to the accompanying drawings and specific examples. In the description of the present application, the "top" and "bottom" orientations and positional relationships are orientations and positional relationships based on a state in which a battery or an electric vehicle is normally used, such as the orientations and positional relationships in fig. 1 and 5, it is to be understood that these orientation terms are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1 to 5, in an embodiment of the present application, a power battery 100 includes a housing 10 and a handle assembly 20. The housing 10 includes a top surface 10a and an end surface 10b adjacent to the top surface 10 a. The handle assembly 20 is connected to the housing 10. The handle assembly 20 is configured to be lifted on one side of the top surface 10a and one side of the end surface 10 b.

The handle assembly 20 can be lifted on one side of the top surface 10a, that is, the handle assembly 20 can be forced on one side of the top surface 10a so that the power cell 100 can move in a direction away from or toward the top surface 10 a. The handle assembly 20 can be lifted on one side of the end face 10b, that is, the handle assembly 20 can be forced on one side of the end face 10b so that the power cell 100 can be moved in a direction away from or toward the end face 10 b. The technical problem that in the prior art, only the lifting handle is arranged on the top surface of the power battery and the power battery can be lifted on the top surface is solved. Since the top surface 10a is adjacent to the end surface 10b, the handle assembly 20 can be pulled in two intersecting directions, thereby facilitating the power cell 100 to be moved in the two intersecting directions.

Referring to fig. 5, the electric vehicle generally includes a receiving cavity 200 for receiving the power battery 100, which is open at one end. The power battery 100 is placed in the accommodating cavity 200. There is a cover plate 300 at the opening of the receiving cavity 200. The cover plate 300 is used for covering the power battery 100. The cover plate 300 is generally not movable relative to the accommodating cavity 200, and therefore, when the power battery 100 needs to be taken out from the accommodating cavity 200, the power battery 100 needs to be moved a distance away from the end face 10b, avoid the cover plate 300, and then move away from the top face 10a, so that the power battery 100 can be removed from the accommodating cavity 200. The power battery 100 provided by the embodiment of the application can apply force to the handle assembly 20 on one side of the end surface 10b, so that the power battery 100 moves along the direction departing from the end surface 10b, and therefore, the power battery 100 can be moved for a certain distance in the direction departing from the end surface 10 b. Then, a force is applied to the handle assembly 20 on one side of the top surface 10a to allow the power cell 100 to move away from the top surface 10a, so that the power cell 100 can be removed from the receiving cavity 200. Therefore, the power cell 100 is easily removed from the receiving cavity 200 through the handle assembly 20. As such, the power battery 100 provided in the embodiment of the present application is particularly suitable for a scenario where two power batteries 100 are placed in the accommodating cavity 200.
