[0002] The power battery cover plate, as an important component of the battery pack, not only bears the functions of sealing and protection, but also has an explosion-proof valve structure built-in, which is used to release pressure when the internal pressure of the battery abnormally rises to prevent the battery from exploding.

[0003] During the manufacturing process of the power battery cover plate, due to factors such as material, process or operation, the explosion-proof valve may have depression and other adverse phenomena. These depressions not only affect the appearance quality of the cover plate, but more importantly, they may affect the normal opening function of the explosion-proof valve, thereby threatening the safety performance of the battery.

[0004] For the problem of depression of the explosion-proof valve, the existing repair methods mainly rely on manual repair or the use of conventional repair tools for repair. However, these methods have encountered many challenges in actual application. In particular, on the finished cover plate after assembly with the stop frame, due to the space limitation and the particularity of the position of the explosion-proof valve, the conventional repair tools and repair methods often cannot fully contact the explosion-proof valve, resulting in poor repair effect. In addition, these repair methods may also cause scratches, marks and other appearance defects on the surface of the explosion-proof valve, further affecting the overall quality and aesthetics of the cover plate.

[0005] In summary, the existing power battery cover plate explosion-proof valve depression repair method has many deficiencies, and there is an urgent need for a more efficient, safe and non-destructive repair solution to solve this problem. UTILITY MODEL CONTENTS

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0026] The present embodiment provides a power battery cover plate explosion-proof valve recess repair device for repairing the recess of the explosion-proof valve 9 on the power battery cover plate 3, wherein the explosion-proof valve 9 is built in one end of the power battery cover plate 3, and the upper surface of the explosion-proof valve 9 is provided with a blue film 8, which is installed on the power battery cover plate 3 to protect the explosion-proof valve 9 and prevent external pollution.

[0027] As shown in Figures 1-4 A power battery cover plate explosion-proof valve recess repair device includes an upper cover 1, a lower cover 2, a sealing ring 5, an air outlet hole 7 and an air inlet hole 6. The upper cover 1 and the lower cover 2 are rotatably connected by a hinge 4. A rectangular slot is formed in the center of the upper cover 1, which not only avoids interference with the protrusions on the upper surface of the power battery cover plate 3 when the upper cover 1 is closed, but also facilitates observation of the state of the explosion-proof valve 9. A sunken table is formed on the upper surface of the lower cover 2. The sealing ring 5 is placed on the sunken table of the lower cover 2 and tightly fits the inner wall of the sunken table to ensure the sealing property. The height of the sealing ring 5 is equal to that of the sunken table, and the inner ring thereof tightly contacts the power battery cover plate 3 to further ensure the sealing effect. An air inlet hole 6 is formed on one side of the lower cover 2 for the inlet of compressed air. An air outlet hole 7 is formed on the sunken table. The air inlet hole 6 communicates with the air outlet hole 7. The air outlet hole 7 is located at the bottom of the explosion-proof valve 9 and is aligned with the circular hole at the bottom of the power battery cover plate 3. The air flow enters from the air inlet hole 6, flows out from the air outlet hole 7 and flows into the power battery cover plate 3 to repair the recess of the explosion-proof valve 9 built in the power battery cover plate 3.

[0028] The use principle of the present embodiment is as follows.

[0029] First, open the upper cover 1, put the power battery cover plate 3 with the recess problem of the explosion-proof valve 9 into the device, ensure that the recess of the explosion-proof valve 9 is aligned with the air outlet hole 7, then close the upper cover 1, and make the sealing ring 5 tightly contact the power battery cover plate 3 to form a sealed space.

[0030] Through the air inlet hole 6 into the device into compressed air, due to the tight cooperation between the sealing ring 5 and the power battery cover plate 3, a closed air pressure environment is formed, with the gradual increase of air pressure, the compressed air in the device forms a certain pressure.

[0031] Under the action of air pressure, the explosion-proof valve 9 with soft material and thin thickness begins to deform and gradually returns to its original state, and the concave problem on the power battery cover plate 3 is effectively solved.

[0032] Since the whole repair process is a non-contact operation based on air pressure, the appearance defects such as scratches and marks caused by the direct contact of the repair tool with the explosion-proof valve 9 are avoided. At the same time, since the air pressure acts quickly and uniformly, the repair efficiency is significantly improved.

[0033] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
