Description

Lifting point structure, battery pack and vehicle Technical Field The application relates to the technical field of new energy, in particular to a lifting point structure, a battery pack and a vehicle. Background With the development of science and technology and the continuous rising of energy demands, the battery pack is increasingly widely used. The battery pack is increasingly charged and the weight of the battery pack is also increasing, and the battery pack is typically connected to the vehicle chassis via a suspension point structure. In order to increase the mode of the battery pack and enhance the column collision resistance of the battery pack, a hanging point structure is generally arranged in the middle of the battery pack and assembled with the battery pack as a whole. However, the lifting point structure is sealed with the whole vehicle through the sealing ring, but the sealing ring is easy to fall off in the transportation process. Disclosure of utility model The embodiment of the application provides a hanging point structure, a battery pack and a vehicle, which are used for achieving the effect of reducing the falling-off of a first sealing element. In a first aspect, an embodiment of the present application provides a hanging point structure, including: A body having a first end; The protective cover is detachably connected with the first end of the body; When the protective cover is in a first use state, the protective cover is arranged at the first end of the body and covers the end face of the first end of the body, and when the protective cover is in a second use state, the protective cover is separated from the first end of the body. In some possible embodiments, the shield cap is interference fit with the first end of the body when the shield cap is in the first use state. In some possible embodiments, the protective cover is formed by a dipping process or an injection molding process; and/or, the protective cover is made of polyvinyl chloride. In some possible embodiments, the end face of the first end of the body is provided with an annular groove; The hanging point structure further includes a first seal disposed within the annular groove and located between the shield cap and the body. In some possible embodiments, the area of the shield cap opposite the annular groove is convex in a direction away from the first end of the body. In some possible embodiments, the body includes a connector; The connecting piece is provided with a first through hole, and the first end of the connecting piece forms the first end of the body; the protective cover also covers the first through hole. In some possible embodiments, the connecting member includes a first segment, a second segment, and a third segment sequentially connected along an extension direction of the first through hole; The outer peripheral surface of the second section protrudes from the outer peripheral surface of the first section and protrudes from the outer peripheral surface of the third section; The protective cover covers a portion of the surface of the first through hole, a surface of the first segment facing away from the second segment, an outer peripheral surface of the first segment, a surface of the second segment facing away from the third segment, and at least a portion of the outer peripheral surface of the second segment. In some possible embodiments, the first segment is hexagonal; And/or the second segment is circular or elliptical; And/or, the body further comprises: a first sleeve connected to the second end of the connector; The second sleeve is connected with one end of the first sleeve, which is far away from the connecting piece, and one end of the second sleeve, which is far away from the first sleeve, is also provided with a limiting part. In a second aspect, embodiments of the present application provide a battery pack including a case, and a hanging point structure as described above disposed on the case. In a third aspect, embodiments of the present application provide a vehicle comprising a battery pack as described above. In the hanging point structure, the battery pack and the vehicle provided by the embodiment of the application, the body is provided with the first end, the protective cover is detachably connected with the first end of the body, when the protective cover is in a first use state, the protective cover is arranged at the first end of the body and covers the end face of the first end of the body, and when the protective cover is in a second use state, the protective cover is separated from the first end of the body.
