The battery support 10 may at least partially surround the battery, for example, the battery support 10 surrounds the battery for one revolution. The shape of the battery holder 10 matches the shape of the battery, for example, when the battery is of a rectangular parallelepiped or approximately rectangular parallelepiped structure, the battery holder 10 is a rectangular frame.

Taking the battery support 10 as a rectangular support for example, the frame body comprises two first frame bodies which are oppositely arranged and two second frame bodies which are oppositely arranged, so as to form a rectangular frame body, wherein the first frame body and the second frame body are of split type structures. As shown in fig. 3, the battery holder 10 may include a first frame plate 101 (first frame 11), a second frame plate 102 (second frame 12), a third frame plate 103 (first frame 11), and a fourth frame plate 104 (second frame 12), with the first frame plate 101, the second frame plate 102, the third frame plate 103, and the fourth frame plate 104 being connected end to end in this order. In the battery bracket mounting process, each frame body is respectively mounted on the peripheral side surface of the battery from the direction perpendicular to the battery side surface, namely, four frame plates are respectively mounted on the battery surface from four directions perpendicularly.

Each frame body is respectively arranged on the peripheral side face of the battery from the direction perpendicular to the side face of the battery, so that the problem that the frame body possibly scratches an insulating layer of the outer wall of the battery when the battery is arranged in the frame body due to too small gap between the frame body and the outer wall of the battery caused by machining tolerance is avoided, and the yield of the battery device is improved.

In a possible embodiment of the present disclosure, the first frame 11 and the second frame 12 are two adjacent frame plates of the first frame plate 101, the second frame plate 102, the third frame plate 103, and the fourth frame plate 104. For example, the first frame 11 is a first frame plate 101, and the second frame 12 is a second frame plate 102. The first frame 11 may be a short side of the battery holder 10, and the second frame 12 may be a long side of the battery holder 10. Or the first frame 11 may be a long side of the battery holder 10 and the second frame 12 may be a short side of the battery holder 10.

In another possible embodiment of the present disclosure, the first side frame plate 101 and the second side frame plate 102 are integrally formed, the third side frame plate 103 and the fourth side frame plate 104 are integrally formed, the first frame 11 includes the first side frame plate 101 and the second side frame plate 102, and the second frame 12 includes the third side frame plate 103 and the fourth side frame plate 104.

When the frame body is a rectangular frame, the first frame body 11 at least covers a first edge of the frame body, the second frame body 12 at least covers a second edge of the frame body, the first edge and the second edge of the frame body are adjacent, and an end portion of the first frame body 11, which is close to the second frame body 12, is abutted against the second frame body 12. The first side of the frame may be a long side, the second side may be a short side, or the first side of the frame may be a short side, and the second side may be a long side.

The first frame 11 covers the first side, the second frame 12 covers the second side, and the end part of the first frame 11 close to the second frame 12 is abutted to the second frame 12, so that the battery bracket 10 on the first side of the frame, namely the first side of the battery, is only provided with a connecting gap at the end part, and the insulating performance and the appearance consistency of the battery bracket 10 are improved.

The first frame body 11 is provided with a connecting hole 13, the second frame body 12 is provided with an elastic buckle 14, the elastic buckle 14 is connected to the connecting hole 13, and the elastic buckle 14 is abutted with the first frame body 11. The elastic buckle 14 has an initial state and a compressed state, and when the elastic buckle 14 is disposed in the connection hole 13, the elastic buckle 14 is switched from the initial state to the compressed state, and the elastic buckle 14 applies a preset force to the second frame 12.

After the elastic buckle 14 is switched from the initial state to the compressed state, the elastic buckle 14 is compressed, and the compressed elastic buckle 14 applies a reaction force to the hole wall of the connecting hole 13, so that a preset pretightening force is provided between the first frame 11 and the second frame 12, and the connection stability of the battery bracket 10 is improved.

The first frame 11 includes a main body section 111 and a connection section 112, the connection section 112 is disposed at an end of the main body section 111, and the extension direction of the connection section 112 is different from the extension direction of the main body section 111, and the connection hole 13 is disposed at the connection section 112; the second frame 12 is at least partially covered on the outer side of the connecting section 112, and the side of the connecting section 112 away from the battery is the outer side.

The main body section 111 and the connection section 112 may be vertically disposed, and the connection section 112 is disposed at an end of the main body section 111, and the connection hole 13 on the connection section 112 is a through hole. The connection hole 13 may be positioned adjacent to the body section 111, or a gap may be provided between the connection hole 13 and the body section 111.

The second frame 12 and the main section 111 of the first frame 11 are arranged vertically, that is, the second frame 12 and the connecting section 112 are arranged in parallel. The elastic buckle 14 is arranged on the inner side of the second frame body 12, and the orthographic projection of the elastic buckle 14 on the connecting section 112 is at least partially overlapped with the connecting hole 13.

In a possible embodiment of the present disclosure, as shown in fig. 4, the elastic buckle 14 may include a first elastic arm 141 and a second elastic arm 142, where the first elastic arm 141 and the second frame 12 are connected; the second elastic arm 142 is connected to the first elastic arm 141, and the second elastic arm 142 is not connected to the second frame 12 (the second elastic arm 142 is suspended). The first elastic arm 141 and the second elastic arm 142 are respectively inserted into the connecting hole 13, and the first elastic arm 141 and the second elastic arm 142 are respectively abutted against the hole wall of the connecting hole 13.

When the first elastic arm 141 and the second elastic arm 142 are inserted into the connecting hole 13, at least one of the first elastic arm 141 and the second elastic arm 142 is elastically deformed, so that a pretightening force is applied to the hole wall of the connecting hole 13, so that no relative displacement occurs between the first frame 11 and the second frame 12, and abrasion of the outer wall of the battery during vibration is avoided. For example, the first elastic arms 141 and the second elastic arms 142 are aligned in the first direction (the longitudinal direction of the second frame 12). The second elastic arm 142 may be disposed at a side of the first elastic arm 141 remote from the first frame 11. Alternatively, as shown in fig. 5, the second elastic arm 142 may be provided at a side of the first elastic arm 141 near the first frame 11.

In the initial state, at a position corresponding to the connection hole 13, a distance between a face of the first elastic arm 141 away from the second elastic arm 142 and a face of the second elastic arm 142 away from the first elastic arm 141 is greater than a dimension of the connection hole 13 in the first direction.

One end of the first elastic arm 141, which is far from the second frame 12, is connected to one end of the second elastic arm 142, which is far from the second frame 12. For example, the first elastic arm 141 and the second elastic arm 142 are directly connected to form a V-shaped elastic buckle 14; or the first elastic arm 141 and the second elastic arm 142 are connected through the transition portion 143 to form the U-shaped or W-shaped elastic buckle 14. When the elastic buckle 14 is in a U shape, the transition part 143 is in a circular arc shape, and when the elastic buckle 14 is in a W shape, the transition part 143 is in an inverted V structure.

The first elastic arm 141 is connected to the second frame 12, and the second elastic arm 142 is suspended relative to the second frame 12. When the elastic buckle 14 extends into the connecting hole 13, the first elastic arm 141 and the second elastic arm 142 elastically abut against the wall of the connecting hole 13. When the connecting hole 13 is arranged next to the main body, the surface of the main body is flush with the wall of the connecting hole 13, the second elastic arm 142 can be elastically abutted against the surface of the main body, the abutting area of the second elastic arm 142 is increased, and the connection stability of the battery bracket 10 is improved.

In another possible embodiment of the present disclosure, as shown in fig. 6, the elastic buckle 14 includes a first elastic arm 141 and a second elastic arm 142, and the first elastic arm 141 and the second frame 12 are connected; the second elastic arm 142 is connected to the second frame 12, the first elastic arm 141 and the second elastic arm 142 are disposed at intervals, and the first elastic arm 141 and the second elastic arm 142 are not connected. The first elastic arm 141 and the second elastic arm 142 are respectively inserted into the connecting hole 13, and the first elastic arm 141 and the second elastic arm 142 are respectively abutted against the hole wall of the connecting hole 13.

The first elastic arm 141 and the second elastic arm 142 may be arranged along the first direction (the length direction of the second frame 12), and in the initial state, a distance between a surface of the first elastic arm 141 away from the second elastic arm 142 and a surface of the second elastic arm 142 away from the first elastic arm 141 is greater than a dimension of the connection hole 13 along the first direction. When the first elastic arm 141 and the second elastic arm 142 extend into the connection hole 13, at least one of the first elastic arm 141 and the second elastic arm 142 is elastically deformed, so that the first elastic arm 141 and the second elastic arm 142 provide a pre-tightening force to the first frame 11.

It will be appreciated that, as shown in fig. 7, the elastic buckle 14 may also include only one elastic arm, so as to implement elastic engagement and limitation. At this time, the elastic arm extends into the connection hole 13, and the elastic arm elastically abuts against the wall of the connection hole 13.

Further, the frame provided in the embodiments of the present disclosure may further include a limiting member 15, where the limiting member 15 is connected to the elastic buckle 14, and a gap is formed between the limiting member 15 and the second frame 12, and the first frame 11 is at least partially clamped in the gap. The elastic buckle 14 is fixed on the first frame 11 through the limiting piece 15, so that the connection stability of the first frame 11 and the second frame 12 is further improved.

Wherein, the limiting piece 15 can be a protruding part on the elastic buckle 14. When the elastic buckle 14 includes the first elastic arm 141 and the second elastic arm 142, the stoppers 15 may be provided at the first elastic arm 141 and the second elastic arm 142, respectively. For example, a limiting protrusion is disposed on a surface of the first elastic arm 141 away from the second elastic arm 142, and a limiting protrusion is disposed on a surface of the second elastic arm 142 away from the first elastic arm 141.

The gap between the stopper 15 and the second frame body 12 may be the same as the thickness of the connection section 112 of the first frame body 11, or the gap between the stopper 15 and the second frame body 12 may be slightly larger than the thickness of the connection section 112 of the first frame body 11. The connecting section 112 is clamped in the gap between the second frame 12 and the limiting member 15 to block the relative movement between the first frame 11 and the second frame 12.

One end of the limiting piece 15, which is far away from the second frame body 12, is provided with a guiding part, and the guiding part is used for guiding when the first frame body 11 is clamped with the second frame body 12. For example, the guide portion may be an inclined surface provided at an end of the stopper 15 remote from the second frame 12. When the first frame 11 and the second frame 12 are buckled, the elastic buckle 14 stretches into the connecting hole 13, when the limiting piece 15 stretches into the connecting hole 13, the limiting piece 15 is pressed into the connecting hole 13 by using an inclined guide surface, and the limiting piece 15 is clamped on the surface, far away from the second frame 12, of the connecting section 112 after passing through the connecting hole 13.
