[0002] With the development of the economy, new energy sources such as electricity are increasingly valued, and their importance is self-evident. Therefore, safety tests must be carried out on various parts of the battery module to ensure that they meet safety standards when leaving the factory. Among the various tests on the battery module, tensile testing of the welding performance of the battery side panels is an indispensable test. However, the existing tensile testing device can only test battery side panels of fixed sizes, and the battery side panels are prone to sliding during the tensile test. When the tensile force is too large, the welding parts of the battery side panels are prone to breakage, and debris is splashed, leading to safety accidents. Therefore, a limiting structure for a battery side panel tensile testing device is required.

[0003] The existing limiting structure of a battery side panel tensile testing device cannot detect battery side panels of different sizes during operation, has poor fixing effect, and cannot provide protection. Therefore, a limiting structure of a battery side panel tensile testing device is urgently needed. Utility Model Content

The top outer wall of the device base is mounted with the rotating shaft, the outer wall of the rotating shaft is mounted with the baffle, and the outer wall of the baffle is mounted with the magnetic block.

[0013] Preferably, the baffle is symmetrically arranged with the central axis of the device base as the center, and the baffle forms a rotating structure with the device base through a rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model has a limiting mechanism, in which the limiting clamping plate and the adjusting rod are movably connected, and the adjusting rod and the adjusting sleeve are threadedly connected.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] The present application provides a battery side panel tensile testing device for performing a tensile test on the welding performance of the battery side panel. Specifically, the two sides of the battery side panel are fixed, and the battery side panel is pulled by applying pressure to test the tensile strength of the battery side panel to meet the safety requirements of battery module assembly. When the battery side panel is fixed, an adjustment device can be used to meet the test requirements of battery side panels of different sizes, thereby improving the applicability of the device.

[0027] See also Figures 1 to 3 , Figure 3A schematic diagram of the limiting mechanism 8 of the present application is shown, which includes a limiting splint 801, an adjusting rod 802 and an adjusting sleeve 803. The adjusting rod 802 and the adjusting sleeve 803 are threadedly connected, and the limiting splint 801 and the adjusting rod 802 are movably connected. In subsequent processes, it is necessary to tighten the threads by rotating the adjusting sleeve 803 and the adjusting rod 802, and push the limiting splint 801 to slide inward through the displacement of the adjusting sleeve 803, so that the limiting splint 801 is tightly fitted with the side wall of the battery side plate 10, thereby squeezing and fixing the battery side plate 10 that needs to be tensile tested to prevent the battery side plate 10 from loosening, and the setting of the limiting splint 801 is adjusted in position through the adjusting sleeve 803, which can meet the fixing requirements of battery side plates 10 of different sizes.

[0028] See also Figure 4 , Figure 4 The schematic diagram of the anti-skid protection mechanism 9 of the present application is shown, and the anti-skid protection mechanism 9 includes a fixing plate 901, anti-skid particles 902 and a positioning rod 903. The fixing plate 901 is threadedly connected to the limiting clamp 801 through the positioning rod 903. Before the limiting clamp 801 clamps and fixes the battery side plate 10, the fixing plate 901 needs to be passed through the interior through the positioning rod 903 and threadedly fixed to the limiting clamp 801, and the surface of the fixing plate 901 is provided with anti-skid particles 902. The setting of the fixing plate 901 is to avoid excessive pushing pressure of the limiting clamp 801, which causes surface wear of the battery side plate 10 and plays a role of buffering protection. The setting of the anti-skid particles 902 is to increase the friction between the contact surface of the fixing plate 901 and the battery side plate 10, so as to avoid the battery side plate 10 sliding off due to low friction during the tensile test, thereby affecting the test effect.

[0029] See also Figure 5 , Figure 5 A schematic diagram of the protective mechanism 11 of the present application is shown. The protective mechanism 11 includes a rotating shaft 1101, a baffle 1102 and a magnetic block 1103. The baffle 1102 is fixed by adsorption through the magnetic block 1103. The baffle 1102 forms a rotating structure with the device base 1 through the rotating shaft 1101. Due to the different tensile strengths of different battery side panels 10, when the battery side panels 10 are subjected to a tensile test, the battery side panels 10 are pulled by excessive pressure and are prone to breakage, fragments flying, and safety accidents. The baffle 1102 is set to rotate and open and close with the rotating shaft 1101 as the end point. When the baffle 1102 rotates to the appropriate position, the baffle 1102 is adsorbed and fixed by the magnetic block 1103, so that the baffle 1102 is in a closed state, thereby shielding and protecting the internal battery side panels 10, avoiding the breakage of the battery side panels 10 and causing fragments to splash, thereby increasing the safety of the device.

[0030] Working principle: When in use, first move the device to the desired position, and then place the battery side plate 10 in the fixed plate 901, and the anti-skid particles 902 are tightly fitted with the outer wall of the battery side plate 10, and the anti-skid particles 902 are epoxy resin particles. When using the device, the setting of the anti-skid particles 902 increases the friction between the fixed plate 901 and the battery side plate 10, preventing the battery side plate 10 and the fixed plate 901 from sliding off during the tensile test, affecting the accuracy of the test data, and the fixed plate 901 is prone to wear due to long-term use. The threaded connection method of the positioning rod 903 is used to facilitate the replacement of the fixed plate 901, increase the stability of the device and the convenience of installation, and then tighten the thread by rotating the adjustment sleeve 803 and the adjustment rod 802 to push The position of the limit clamp 801 is adjusted to control the distance between the limit clamps 801, so that the device can clamp and fix battery side panels 10 of different sizes, and then perform stretching testing to increase the applicability of the device. Then, by starting the transmission motor 5, the transmission gear 6 is driven to engage with the transmission tooth plate 2 to make the stretching platforms 4 on both sides drive the battery side panels 10 to perform stretching testing. Finally, the baffle 1102 is rotated and closed around the rotating shaft 1101, and then adsorbed and fixed by the magnetic block 1103 to avoid the battery side panel 10 from breaking due to the large stretching force during the stretching test, and the debris splashing to cause harm to the staff, thereby increasing the safety of the device. In this way, the use process of the device is completed.
