[0023] Working principle:

[0024] The modular explosion-proof cylindrical battery test fixture mainly comprises a shell 1, a clamping assembly 2 and a replacement assembly 3, the shell 1 serves as the basic framework of the whole test fixture and provides mounting space and external protection for other components, so that the internal components can work in a relatively stable and safe environment, the clamping assembly 2 is fixedly connected to the inner wall of the shell 1 and is an important part for realizing the stable positioning of the cylindrical battery in the fixture, and through a specific sliding clamping mode, appropriate clamping force is applied to the cylindrical battery to keep it in a fixed position, so that the test can be carried out smoothly, and the replacement assembly 3 is closely connected with the clamping assembly 2 and is fixedly connected to the outer wall of the clamping assembly 2, which is mainly used for cylindrical batteries of different sizes and can be adjusted to adapt to cylindrical batteries of various specifications by virtue of its structural characteristics, thereby enhancing the universality and adaptability of the fixture.

[0025] The replacement assembly 3 comprises a main clamping plate 31, an inclined insertion plate 32, a positive electrode insertion block 33, a sliding column 34, an auxiliary clamping plate 35 and a negative electrode insertion plate 36, and each component cooperates with each other to realize the adaptation function of cylindrical batteries of different sizes.

[0026] The main clamping plate 31 is a key basic component of the replacement assembly 3, and the bottom thereof is in sliding connection with the inner wall of the shell 1, which enables the main clamping plate 31 to slide in the shell 1, laying a foundation for subsequent adjustment of the position according to the size of the battery. The positive electrode plug 33 is in sliding connection with the inner wall of the main clamping plate 31 through the slide column 34, which not only plays a connecting role but also provides a guide for the sliding of the positive electrode plug 33. The oblique plug plate 32 also slides on the inner wall of the main clamping plate 31 and is in contact with the outer wall of the slide column 34, so that the position of the slide column 34 is limited by the oblique plug plate 32.

[0027] The auxiliary clamping plate 35 is arranged on the outer wall of the main clamping plate 31 and is in sliding connection with the inner wall of the shell 1, so that it can also slide along the inner wall of the shell 1. The auxiliary clamping plate 35 cooperates with the main clamping plate 31 to clamp and position the cylindrical battery. The negative electrode plug plate 36 slides on the inner wall of the auxiliary clamping plate 35.

[0028] When it is necessary to adapt to cylindrical batteries of different sizes, the oblique plug plate 32 on the main clamping plate 31 and the auxiliary clamping plate 35 is slid out, and then the positive electrode plug 33 and the negative electrode plug plate 36 are slid out of the main clamping plate 31 and the auxiliary clamping plate 35. After the positive electrode plug 33 and the negative electrode plug plate 36 are slid out, the positive electrode plug 33 and the negative electrode plug plate 36 corresponding to the type of the cylindrical battery are replaced, and the positive electrode plug 33 and the negative electrode plug plate 36 are respectively slid into the corresponding main clamping plate 31 and auxiliary clamping plate 35. After the slide column 34 on the positive electrode plug 33 and the negative electrode plug plate 36 is slid into the main clamping plate 31 and the auxiliary clamping plate 35, the oblique plug plate 32 is slid into the main clamping plate 31 and the auxiliary clamping plate 35. The slide column 34 is provided with a plug slot corresponding to the oblique plug plate 32, so that the position of the slide column 34 is limited by the oblique plug plate 32, and the position of the positive electrode plug 33 and the negative electrode plug plate 36 is limited, so that cylindrical batteries of different sizes can be adapted.

[0029] The clamping assembly 2 is mainly composed of a limiting column 21, a sliding plate 23, a tension spring 22, a conductive plate 24, a positive electrode tube 25, a negative electrode tube 26, and a conductive block 27, and each component cooperates to realize the clamping and electrode connection functions of the cylindrical battery.

[0030] The limiting column 21 is linearly arrayed along the outer wall of the shell 1, and the outer wall thereof is in sliding connection with the sliding plate 23, thereby providing a guide and limiting effect for the sliding of the sliding plate 23, so that the sliding plate 23 can only move in the direction defined by the limiting column 21. One end of the tension spring 22 is fixedly connected to the outer wall of the sliding plate 23, and the other end is fixed to another group of sliding plates 23. The tension spring 22 uses its elastic force to pull the two groups of sliding plates 23 close to each other, thereby driving the main clamping plate 31 and the auxiliary clamping plate 35 close to each other, and clamping the position of the cylindrical battery.

[0031] The conductive plate 24 is fixedly connected to the top of the shell 1, which plays a role in conducting current and providing support and connection basis for related electrode components during testing. The conductive block 27 is slidingly connected to the inner wall of the top of the conductive plate 24, which can move to a certain extent in the conductive plate 24, and the top of the conductive block 27 is fixedly connected to the bottom of the main clamping plate 31. Thus, when the main clamping plate 31 is adjusted in position due to the size of the battery and other reasons, the conductive block 27 will move synchronously, ensuring the continuity of the electrode connection.

[0032] The positive electrode tube 25 is fixedly connected to the outer wall of the conductive plate 24, which is in turn fixedly connected to the outer wall of the top of the shell 1, and is used to transmit current during testing to ensure that the current can be conducted from the external test circuit to the positive electrode of the cylindrical battery according to the predetermined path. The negative electrode tube 26 is also fixedly connected to the shell 1, and the outer wall thereof is slidingly connected to the bottom of the auxiliary clamping plate 35 through the electrode plate, realizing electrical connection with the negative electrode of the cylindrical battery.

[0033] When the cylindrical battery is placed in the clamp, the battery will generate a horizontal force on the main clamping plate 31 and the auxiliary clamping plate 35, and the tension of the tension spring 22 will force the two sets of sliding plates 23 to move closer to each other along the limiting column 21. As the sliding plates 23 slide, the distance between the main clamping plate 31 and the auxiliary clamping plate 35 will gradually decrease, thereby tightly clamping the cylindrical battery and fixing it in the clamp. At the same time, the electrode connection components such as the conductive block 27, the positive electrode tube 25 and the negative electrode tube 26 will also accurately contact the positive and negative electrodes of the battery, thereby constructing a complete test circuit, allowing the external test equipment to test various performance indicators of the cylindrical battery through the clamp.

[0034] In actual use, the main components of the shell 1, the clamping assembly 2 and the replacement assembly 3 work closely together to ensure the normal operation of the test clamp and the smooth development of the cylindrical battery test.

[0035] The shell 1 provides a stable mounting base and external protection for the clamping assembly 2 and the replacement assembly 3. The internal space structure is adapted to the movement and installation requirements of the sliding plates 23, limiting columns 21 and other components of the clamping assembly 2, and the inner wall provides support and guidance for the sliding of the main clamping plate 31, auxiliary clamping plate 35 and other components of the replacement assembly 3.

[0036] The clamping assembly 2 realizes the clamping and fixing of the cylindrical battery and the electrode connection function through the cooperation of the components. It works with the replacement assembly 3 to transmit the contact condition of the positive and negative electrodes of the battery after adjustment by the replacement assembly 3 to the external test circuit through the conductive block 27 and other components. The movement and stress state of the sliding plates 23, tension spring 22 and other structures of the clamping assembly 2 are coordinated with the adjustment operation of the replacement assembly 3 according to the size of the battery.

[0037] The replacement assembly 3 is flexibly adapted to cylindrical batteries of different sizes by means of the adjustable characteristics of its components, and its connection relationship with the clamping assembly 2 and the position adjustment in the shell 1 are consistent with the clamping operation of the clamping assembly 2 and the testing function requirements of the whole fixture, so as to ensure that no matter what size of the cylindrical battery is placed in the fixture, stable fixation, accurate electrode connection and subsequent reliable testing process can be realized through the cooperation of the components, and the actual testing requirements of different cylindrical batteries can be met.

[0038] Through the cooperation of the shell 1, the clamping assembly 2 and the replacement assembly 3, the modular explosion-proof cylindrical battery testing fixture can provide a relatively stable, easy-to-operate and adaptable testing environment for testing work of multiple battery specifications during the cylindrical battery testing process, which is helpful to obtain testing data and ensure the orderly progress of the cylindrical battery testing work, and has certain practical value in the field of cylindrical battery testing.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the scope of protection of the present application.
