Preferred embodiments of the disclosed embodiments are described in detail below, however, other implementations of the disclosed embodiments are possible in addition to these detailed descriptions.

As shown in fig. 1 to 3, the embodiment of the present disclosure provides a case structure 100 of a battery, the case structure 100 including: the rear wall 110, the side wall 120 and the plurality of heat dissipating ribs 150, wherein the rear wall 110 includes a first surface 111 and a second surface 112 located on opposite sides of the rear wall 110, and at least a partial area of the first surface 111 is a non-planar structure 140; the side wall 120 extends from the rear wall 110 toward the second surface 112, and the rear wall 110 and the side wall 120 together define a battery compartment 130 having an opening, the battery compartment 130 for receiving a battery pack 200 within the battery; a plurality of heat sinks 150 are located on the second surface 112 and are in contact with at least the non-planar structure 140.

In the embodiment of the disclosure, the non-planar structure 140 can increase the heat dissipation area of the first surface 111 of the rear wall 110, so as to improve the heat dissipation effect of the heat generated by the battery pack 200. As shown in fig. 1 to 3, the heat dissipating ribs 150 are in contact with the non-planar structure 140, so that a larger heat dissipating area can be obtained at the non-planar structure 140, and further, the heat dissipating effect on the heat generated by the battery pack 200 is further improved.

The non-planar structure 140 may be a surface structure with surface irregularities.

Illustratively, the non-planar structure 140 includes: a cambered surface. As shown in fig. 2 and 3, the non-planar structure 140 is sequentially connected by a plurality of cambered surfaces, which are corrugated in a section perpendicular to the rear wall direction.

Furthermore, as shown in fig. 4, the non-planar structure 140 may further include: serrated surfaces, or, as shown in fig. 5, a combination of serrated surfaces and cambered surfaces.

Fig. 1-3 exemplarily illustrate that a partial region of the second surface 112 has a non-planar structure 140, and another partial region does not have a non-planar structure 140.

It is understood that the first surface 111 may be entirely non-planar structures 140.

The second surface 112 is an inner surface located in the battery compartment 130, and the first surface 111 is an outer surface exposed to the external environment. The rear wall 110 is generally the wall of the housing structure 100 that has the largest contact area with the battery pack 200, namely: the contact area of the rear wall 110 with the battery pack 200 is larger than the contact area of the side wall 120 with the battery pack 200. The non-planar structure 140 and the heat dissipating ribs 150 are added to the first surface 111 of the rear wall 110, so that heat in the battery compartment 130 can be more efficiently dissipated to the external environment, and the heat dissipation efficiency is further improved.

The opening of the battery compartment 130 is at least used for taking and placing the battery pack 200, and facilitates the installation and the disassembly of the battery pack 200.

The heat dissipating ribs 150 not only increase the heat dissipating area of the first surface 111, but also are beneficial to strengthen the housing structure 100.

As shown in fig. 1-3, according to some alternative embodiments, the first surface 111 has a recess 114a, and the non-planar structure 140 is located within the recess 114 a; a plurality of heat sinks 150 are at least partially located within recess 114 a.

The heat dissipation area of the second surface 112 can be further increased by using the inner wall of the groove 114a, and the non-planar structure 140 is disposed in the groove 114a, so that the protruding degree of the non-planar structure 140 on the first surface 111 can be reduced, which is beneficial to improving the flatness of the first surface 111.

The heat dissipating rib 150 contacts the non-planar structure 140 in such a manner as to increase the width of a portion of the heat dissipating rib 150 located in the groove 114a, so that a portion 151 of the heat dissipating rib may extend into the groove 114a, thereby further increasing the heat dissipating area of the first surface 111.

Illustratively, as shown in fig. 1 and 2, the first surface 111 includes: a planar portion 113 and a non-planar portion 114, the non-planar portion 114 having a recess 114a, a portion of the plurality of heat sinks 150 being located on the planar portion 113 and another portion of the plurality of heat sinks 150 being located within the recess 114 a.

According to some alternative embodiments, the height of the non-planar structure 140 is less than or equal to the depth of the groove 114 a. As shown in fig. 3, the non-planar structure 140 may be entirely located within the groove 114a, i.e., the highest point of the non-planar structure 140 does not exceed the height of the planar portion 113, which may reduce the unevenness of the first surface 111.

Illustratively, as shown in fig. 3, the plurality of heat dissipating ribs 150 are flush with the planar portion 113, which may further improve the flatness of the first surface 111 and enhance the use experience of the housing structure 100.

As shown in fig. 6, according to some alternative embodiments, the housing structure 100 further includes: the heat dissipation wall 160, the heat dissipation wall 160 is located in the battery compartment 130 and is attached to the second surface 112, the heat dissipation wall 160 has at least one limit groove 161, and an inner wall of the limit groove 161 is attached to the battery pack 200.

As shown in connection with fig. 6 and 8, the heat dissipation wall 160 is positioned in the battery compartment 130 and can be attached to the battery pack 200 to conduct heat generated from the battery pack 200 to the rear wall 110. The limit groove 161 can better fit with the outer surface of the battery pack 200, increase the contact area with the battery pack 200, and further improve the heat dissipation effect on the battery pack 200.

The heat dissipation wall 160 may be an integral part integrally formed with the rear wall 110, or the heat dissipation wall 160 may be two parts independent of the rear wall 110, and in this case, the heat dissipation wall 160 may be fixed to the rear wall 110 by adhesion, screw connection, or the like.

Alternatively, the inner wall of the limit groove 161 is an arc-shaped inner wall 161a, and the arc-shaped inner wall 161a is matched with the outer wall of the battery pack 200. For example: the shape of the arc inner wall 161a of the limit groove 161 is the same as that of the arc outer wall of the battery pack 200, and the arc inner wall 161a of the arc groove can be completely attached to the outer wall of the battery pack 200.

According to some alternative embodiments, the housing structure 100 further comprises: and the heat conducting gel is positioned in the limit groove 161 and between the heat radiating wall 160 and the battery pack 200.

The heat conducting gel can better conduct the heat generated by the battery pack 200 to the heat dissipation wall 160, reduce the resistance in the heat transfer process, and improve the heat dissipation effect.

As shown in fig. 7, according to some alternative embodiments, the housing structure 100 further includes: and a cover 170, the cover 170 being coupled to the sidewall 120 to seal the opening of the battery compartment 130.

The cover 170 can seal the battery compartment 130, so that water, dust and the like in the external environment are reduced from entering the battery compartment 130 to affect the battery pack 200, and the battery pack 200 is protected.

Illustratively, as shown in fig. 7, the cover 170 further has a plugging slot 171, and the plugging slot 171 is used for matching with a plugging column on the host, so that the plugging column is plugged into the plugging slot 171, and the installation of the housing structure 100 and the host is realized. The host refers to a functional component capable of providing a reciprocating pressing force.

The number of the insertion grooves 171 may be one, or may be two or more. Fig. 7 shows, by way of example, 3 plug grooves 171.

As shown in fig. 7 and 8, the embodiment of the present disclosure further provides a battery including: the above-mentioned battery case structure 100, and the battery pack 200, the battery pack 200 is located in the battery compartment 130.

The battery pack is a rechargeable battery pack, and may be a disposable non-rechargeable battery pack.

The battery pack may be a lithium ion battery pack or a lead acid battery pack, but is not limited thereto.

The battery pack includes one single cell, or the battery pack includes at least two single cells. Fig. 8 exemplarily shows that the battery pack has a plurality of unit cells.

Embodiments of the present disclosure also provide a cardiopulmonary resuscitation device including: the battery comprises a host machine and the battery, wherein the host machine is used for providing reciprocating pressing force; a battery is connected to the main body to provide a driving force for the reciprocating pressing force.

For example, the cardiopulmonary resuscitation device may be a chest compression machine.
