Protection structure of battery case top cover exhaust valve

Abstract

The utility model discloses a protective structure of a battery case top cover exhaust valve, which comprises a protective cylinder with an upper end and a lower end opened, the protective cylinder is detachably sleeved outside the exhaust valve, and the top end of the protective cylinder is higher than the top end of the exhaust valve. According to the protection structure of the exhaust valve of the top cover of the battery shell, the protection cylinder is additionally arranged on the exhaust valve, the exhaust valve structure cannot be damaged when slight collision occurs due to errors of battery stacking positions, and exhaust cannot be damaged due to the fact that the exhaust valve structure is wrapped by the protection cylinder.

Description

Technical Field

[0001] The utility model relates to a protective structure for an exhaust valve of a battery shell top cover. Background Art

[0002] The exhaust valve on the top cover of the aqueous sodium ion electronic shell is a raised thin-walled structure, and the circle of plastic on the top of the exhaust valve structure is relatively thin and has no special supporting structure, which is easy to deform when encountering a collision.

[0003] During the production process, the battery needs to be injected with liquid. During the injection, the battery needs to be left still. In order to improve the utilization rate of the site, the batteries will be stacked together. If they are not stacked together, 5-10 times the floor space will be required. The injection will be divided into several steps, and the battery will be moved back and forth several times. During the movement process, if there is an error in positioning, it is easy for the exhaust valve of the lower battery to interfere with the base of the upper battery. When interfering, the exhaust valve structure will be deformed, and eventually lead to the production of defective products. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a protective structure for the exhaust valve of the top cover of a battery shell. A protective cylinder is installed on the exhaust valve. When there is an error in the position of the stacked batteries and a slight collision occurs, the exhaust valve structure will not be damaged because the exhaust valve structure is wrapped by the protective cylinder and the exhaust will not be damaged.

[0005] The technical solution to achieve the above purpose is: a protective structure for the exhaust valve of the top cover of a battery shell, comprising a protective cylinder with openings at the upper and lower ends, the protective cylinder being detachably mounted outside the exhaust valve, and the top end of the protective cylinder being higher than the top end of the exhaust valve.

[0006] In the above-mentioned protective structure for the exhaust valve of the top cover of the battery shell, the inner diameter of the protective cylinder is matched with the outer diameter of the exhaust valve.

[0007] The protective structure of the exhaust valve on the top cover of the battery shell of the utility model is equipped with a protective tube on the exhaust valve. When there is an error in the position of the stacked batteries and a slight collision occurs, the exhaust valve structure will not be damaged because the exhaust valve structure is wrapped by the protective tube and the exhaust will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a diagram of the use state of the protective structure of the battery shell top cover exhaust valve of the utility model;

[0009] Figure 2 It is a schematic diagram of the installation of the protective structure of the exhaust valve of the battery shell top cover of the utility model. DETAILED DESCRIPTION

[0010] In order to enable those skilled in the art to better understand the technical solution of the utility model, the specific implementation method thereof is described in detail below in conjunction with the accompanying drawings:

[0011] See also Figure 1 and Figure 2 The best embodiment of the utility model is a protective structure for the exhaust valve of the top cover of a battery shell, comprising a protective cylinder 1 with openings at the upper and lower ends, the protective cylinder 1 being detachably sleeved outside the exhaust valve 2, and the top of the protective cylinder 1 being higher than the top of the exhaust valve 2. The inner diameter of the protective cylinder 1 is adapted to the outer diameter of the exhaust valve 2.

[0012] In the protective structure of the exhaust valve of the battery shell top cover of the utility model, during the battery processing, the protective cylinder 1 protects the exhaust valve 2. When there is a positioning error or a slight collision occurs, the exhaust valve 2 structure will not be damaged because the exhaust valve 2 structure is wrapped by the protective cylinder 1, and the exhaust function of the exhaust valve 2 will not be damaged. When the battery is finally shipped, the protective cylinder 1 can be removed for recycling, so that the protective cylinder 1 can be reused.

[0013] In summary, the protective structure of the exhaust valve on the top cover of the battery shell of the utility model is equipped with a protective tube on the exhaust valve. When there is an error in the position of the stacked batteries and a slight collision occurs, the exhaust valve structure will not be damaged because the exhaust valve structure is wrapped by the protective tube and the exhaust will not be damaged.

[0014] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
