Description

Technical Field

[0001] The utility model relates to the field of battery cap structures, in particular to a battery cap structure for a steel shell aqueous zinc ion battery. Background Art

[0002] Steel-cased aqueous zinc-ion batteries are secondary batteries that use an aqueous solution as the electrolyte. Their operating principle is based on the reversible migration of zinc ions between the positive and negative electrodes. The battery cap structure of steel-cased aqueous zinc-ion batteries is a crucial component of the battery, significantly impacting its safety, sealing, and service life.

[0003] The battery cap structure of the existing steel-shell aqueous zinc-ion battery consists of a cap body and a contact protrusion. The contact protrusion is fixedly integrated with the cap body. During use, the contact protrusion cannot be elastically deformed, and it is easy for the contact to be too tight or too loose. If the contact is too tight, it will affect the rapid disassembly and assembly of the battery. If the contact is too loose, it will cause poor battery installation stability, poor contact, etc. The effect of use is average. When the battery is used in a relatively humid environment, the contact protrusion is prone to rust and damage, and the contact protrusion cannot be replaced, which will affect the normal power supply use. The effect of use is average. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1-4 As shown, a battery cap structure for a steel-shell aqueous zinc-ion battery includes a cap body 1, a protective pad 2 is provided on the cap body 1, a circular groove 3 is provided on the cap body 1, an abutment assembly 4 is installed on the cap body 1, and an elastic contact assembly 5 is provided at the middle position of the lower surface of the cap body 1. The cap body 1 is fixedly connected to the protective pad 2, and an outer rim 6 is provided on the cap body 1. An internal positioning ring 7 is installed on the lower surface of the cap body 1, and an annular groove 8 is provided between the internal positioning ring 7 and the outer rim 6. The elastic contact assembly 5 includes an elastic contact block 501 and a deformation cavity 502. The deformation cavity 502 is opened on the elastic contact block 501, and the elastic contact block 501 is fixed to the cap body 1.

[0020] The cap body 1 is provided with an outer edge 6 and an internal positioning ring 7, which can play a positioning role and ensure the welding effect. The elastic contact component 5 is used to ensure that the cap part and the pole can be in close contact, ensuring the use effect of the cap part.

[0021] When installing the battery cap structure, the cap body 1 is positioned by the annular groove 8 between the outer edge 6 and the internal positioning ring 7, and the cap body 1 is accurately set on the battery steel shell body. At this time, the elastic contact block 501 in the elastic contact component 5 contacts the pole inside the steel shell. After pressing the entire cap, the cap body 1 is in close contact with the end of the steel shell. The elastic contact block 501 is elastically deformed by the force through the deformation cavity 502, so that the elastic contact block 501 is in close contact with the pole. Then the cap body 1 is welded to ensure that the entire cap is fixedly connected to the steel shell, thus completing the installation of the battery cap. When the battery is used, the battery is installed on the relevant device. During this process, the abutment component 4 can undergo elastic deformation to give way, ensuring the rapid installation of the battery. After the installation is completed, the abutment component 4 can provide a stable support effect, ensuring the stable use of the battery.

[0022] Through the above implementation scheme, the abutment component 4 includes an elastic connecting frame 401, a contact base plate 402 and an abutment plate 404. The elastic connecting frame 401 is installed on the cap body 1, and the contact base plate 402 and the abutment plate 404 are installed on the elastic connecting frame 401. The abutment component 4 also includes a connecting block 403, a rubber support frame 405, a snap-in groove 406 and a snap-in column 407. The elastic connecting frame 401 is composed of six elastic sheets. The upper end of the elastic sheet is integrally arranged, and the lower end of the elastic sheet is connected to the cap body 1. The contact base plate 402 and the abutment plate 404 are snap-connected to the elastic connecting frame 401. The connecting block 403 is fixed on the lower surface of the contact base plate 402, the rubber support frame 405 is located in the circular groove 3 on the cap body 1, and the upper end of the rubber support frame 405 is sleeved on the connecting block 403, the clamping groove 406 is opened on the contact base plate 402, the clamping column 407 is fixed on the abutment plate 404, and the clamping column 407 is clamped in the clamping groove 406.

[0023] During battery installation, the contact plate 404 in the contact assembly 4, upon receiving force, applies a force to the contact base plate 402 and the elastic connecting frame 401, causing the elastic connecting frame 401 to elastically deform. Simultaneously, the contact base plate 402 applies a force to the rubber support frame 405 at the connection block 403, causing the rubber support frame 405 to deform and form a buffer, causing the contact assembly 4 to elastically deform and yield, ensuring rapid installation. After battery installation, the elastic connecting frame 401 and the rubber support frame 405 work together to ensure that the contact plate 404 closely contacts the contact components within the battery compartment of the device, thereby ensuring stable contact after battery installation and ensuring normal battery power supply. When the battery is used in a humid environment for a long time, the abutment plate 404 is prone to moisture, rust and damage. The staff can remove the abutment plate 404 for replacement. After the disassembly is completed, the new abutment plate 404 is set to the contact bottom plate 402, so that the clamping column 407 is connected to the clamping groove 406. It has a simple structure, convenient and quick operation, and high flexibility and adaptability in use.

[0024] It should be noted that an abutment assembly 4 is provided on the cap body 1, and an elastic connecting frame 401 is used to install the contact base plate 402 and the abutment plate 404. A rubber support frame 405 is installed on the contact base plate 402 through a connecting block 403, so that the battery is installed and used in an elastic contact manner to prevent the abutment from being too tight or too loose, which is convenient for the disassembly and assembly of the battery and can ensure the stability of the battery. The abutment plate 404 and the contact base plate 402 are installed in a snap-fit ​​manner, which is convenient for disassembly and replacement, thereby ensuring the use effect of the battery and having high flexibility and adaptability.
