Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and specifically relates to a battery pack with a compressive structure. Background Art

[0002] A battery refers to a part of a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate current, and is a device that can convert chemical energy into electrical energy. As an essential item for modern people's work and life, battery packs are widely used in industries such as new energy vehicles.

[0003] For example, in the utility model: "A battery pack with a compressive structure", the publication number is: "CN221379613U". The cross-section of the protective shell of this patent is an arc-shaped structure, so the protective shell can evenly disperse the pressure from above to the bearing box. The fixing plate can provide a certain lateral support force for the protective shell, thereby preventing the protective shell from deforming due to excessive pressure. However, during the implementation of this patent, the contact area between the protective shell and the bearing box is small. When the pressure is transmitted to the bearing box, the local pressure on the bearing box is still large, which is likely to cause local deformation or damage to the bearing box. Therefore, the present utility model provides a battery pack with a compressive structure to solve the above problems. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a battery pack with a compressive structure to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A battery pack with a compressive structure includes a battery pack protective shell, a battery cell protection cover plate, semi-circular compressive support plates, and a battery pack bearing top cover. The top of the battery pack protective shell is equipped with a battery cell protection cover plate, and the top of the battery cell protection cover plate is equipped with a battery pack bearing top cover. Installation slots are provided at both ends of the top of the battery pack protective shell, and a battery pack battery cell is installed inside the battery pack protective shell. Semi-circular compressive support plates are evenly installed on the top inside the battery pack bearing top cover.

[0006] Preferably, guide force columns are evenly installed at both ends of the top of the semi-circular compressive support plates, and the ends of the guide force columns away from the semi-circular compressive support plates are all connected to the battery pack bearing top cover.

[0007] Preferably, force dividing columns are evenly installed at the bottom of the semi-circular compressive support plates.

[0008] Preferably, installation plug plates are installed at both ends of the bottom of the battery pack bearing top cover, and first fixing screw holes are provided on the outer sides of the installation plug plates.

[0009] Preferably, second fixing screw holes are provided at the tops of both ends of the battery pack protective housing, the second fixing screw holes are all communicated with the installation slots, and fixing bolts are threadedly installed inside the second fixing screw holes.

[0010] Preferably, installation sockets are provided at both ends of the top of the battery cell protection cover plate.

[0011] Preferably, an anti-rust layer is provided on the outer sides of the fixing bolts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The battery pack with a compressive structure is equipped with a battery pack protective housing and a battery pack battery cell. When in use, the battery cell protection cover plate is installed above the battery pack protective housing, and the pressure received by the battery pack bearing top cover is directly transmitted to the battery cell protection cover plate. The battery pack protective housing and the battery pack battery cell can be protected through the battery cell protection cover plate, avoiding damage to the battery pack protective housing and the battery pack battery cell due to stress.

[0014] 2. The battery pack with a compressive structure is equipped with a semi-circular compressive support plate, a force guiding pillar and a force dividing pillar. The pressure received by the battery pack bearing top cover is transmitted to the semi-circular compressive support plate through the force guiding pillar. Due to the arc structure of the semi-circular compressive support plate, the semi-circular compressive support plate evenly transmits the pressure to different positions of the battery cell protection cover plate through multiple force dividing pillars, which can increase the stress area of the battery cell protection cover plate, make the stress at different positions of the battery cell protection cover plate uniform, and thus avoid the battery cell protection cover plate from breaking due to excessive local stress, effectively improving the compressive effect.

[0015] 3. The battery pack with a compressive structure is equipped with an installation plug board and a fixing bolt. During installation, the installation plug board can be passed through the installation socket, inserted into the installation slot, and then the fixing bolt is screwed into the second fixing screw hole and the first fixing screw hole, so as to firmly install the battery pack protective housing, the battery cell protection cover plate and the battery pack bearing top cover.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model: A battery pack with a compressive structure, including a battery pack protective housing 1, a battery cell protection cover plate 4, a semi-circular compressive support plate 5 and a battery pack carrying top cover 9. The top of the battery pack protective housing 1 is provided with a battery cell protection cover plate 4, and the top of the battery cell protection cover plate 4 is provided with a battery pack carrying top cover 9. Both ends of the top of the battery pack protective housing 1 are provided with installation slots 3, and a battery pack battery cell 2 is installed inside the battery pack protective housing 1. Semi-circular compressive support plates 5 are uniformly installed on the top inside the battery pack carrying top cover 9.

[0024] As Figures 1 - 5 shown, force guiding pillars 6 are uniformly installed at both ends of the top of the semi-circular compressive support plate 5, and the ends of the force guiding pillars 6 far from the semi-circular compressive support plate 5 are all connected to the battery pack carrying top cover 9. Force dividing pillars 7 are uniformly installed at the bottom of the semi-circular compressive support plate 5. The pressure received by the battery pack carrying top cover 9 is transmitted to the semi-circular compressive support plate 5 through the force guiding pillars 6. Through the arc structure of the semi-circular compressive support plate 5, the semi-circular compressive support plate 5 evenly transmits the pressure to different positions of the battery cell protection cover plate 4 through multiple force dividing pillars 7, which can increase the stress area of the battery cell protection cover plate 4, make the stress at different positions of the battery cell protection cover plate 4 uniform, thereby avoiding the fracture of the battery cell protection cover plate 4 due to large local stress, and effectively improving the compressive effect.

[0025] As Figures 1 - 4As shown in the figure, installation inserts 8 are installed at both ends of the bottom of the battery pack carrying top cover 9, and first fixing screw holes 10 are provided on the outer sides of the installation inserts 8. Second fixing screw holes 11 are provided at the tops of both ends of the battery pack protective housing 1. The second fixing screw holes 11 are all communicated with the installation slots 3, and fixing bolts 12 are threadedly installed inside the second fixing screw holes 11. Antirust layers are provided on the outer sides of the fixing bolts 12. Installation sockets 13 are provided at both ends of the top of the cell protection cover plate 4. During installation, the cell protection cover plate 4 is placed on the top of the battery pack protective housing 1, and the battery pack carrying top cover 9 is placed on the top of the cell protection cover plate 4, so that the installation inserts 8 pass through the installation sockets 13 and are inserted into the installation slots 3. The first fixing screw holes 10 on the installation inserts 8 move to positions directly opposite the second fixing screw holes 11. Workers can screw the fixing bolts 12 into the first fixing screw holes 10 and the second fixing screw holes 11 at the same time to fix the installation inserts 8, thereby fixing the battery pack protective housing 1, the cell protection cover plate 4 and the battery pack carrying top cover 9 to complete the installation process.

[0026] Working principle:

[0027] During installation, the cell protection cover plate 4 is placed on the top of the battery pack protective housing 1, and the battery pack carrying top cover 9 is placed on the top of the cell protection cover plate 4, so that the installation inserts 8 pass through the installation sockets 13 and are inserted into the installation slots 3;

[0028] At this time, the first fixing screw holes 10 on the installation inserts 8 move to positions directly opposite the second fixing screw holes 11. Workers can screw the fixing bolts 12 into the first fixing screw holes 10 and the second fixing screw holes 11 at the same time to fix the installation inserts 8, thereby fixing the battery pack protective housing 1, the cell protection cover plate 4 and the battery pack carrying top cover 9 to complete the installation process;

[0029] During use, when pressure is applied to the top of the battery pack carrying top cover 9, the pressure received by the battery pack carrying top cover 9 is transmitted to the semi-circular compressive support plate 5 through the force guiding strut 6. Due to the arc structure of the semi-circular compressive support plate 5, the semi-circular compressive support plate 5 evenly transmits the pressure to different positions of the cell protection cover plate 4 through multiple component force struts 7, which can increase the force-bearing area of the cell protection cover plate 4 and make the forces at different positions of the cell protection cover plate 4 uniform, thereby preventing the cell protection cover plate 4 from breaking due to excessive local stress;

[0030] Moreover, the cell protection cover plate 4 can protect the battery pack protective housing 1 and the battery pack cell 2 to prevent the battery pack protective housing 1 and the battery pack cell 2 from being damaged by force.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
