[0031] Among them, the pole of the battery and the bar plate are welded and fixed, the test fixture clamps the bar plate to complete the torque strength bottom-up test of the pole by pulling the bar plate. It should be noted that the test fixture is an existing torque test fixture, such as a tension machine.

[0032] The battery in the present embodiment is a square battery, specifically a square aluminum shell battery, that is, the shell of the battery is a cuboid structure as a whole.

[0033] As shown in Figures 1 to 5 The battery test fixture includes a base 30, a positioning assembly 10 and an adjusting assembly 20. The positioning assembly 10 is arranged on the base 30. The positioning assembly 10 includes a positioning shell 110 having a receiving cavity with a top opening for accommodating the battery. The side wall of the positioning shell 110 has a hole structure 1121. One of the bar plates of the battery is exposed outside the receiving cavity through the top opening, and the other bar plate partially penetrates the hole structure 1121 and extends out of the receiving cavity. The adjusting assembly 20 is movably arranged on the positioning shell 110. At least a part of the adjusting assembly 20 extends into the receiving cavity and abuts against the battery. The adjusting assembly 20 is used to provide driving force for the bar plate to penetrate the hole structure 1121.

[0034] The battery test fixture of the application adopts the positioning shell 110 to accommodate the battery, and the battery is limited by adjusting the adjusting assembly 20, which is conducive to flexible positioning of the battery. The battery test fixture of the application has the characteristics of being applicable to clamping batteries of different sizes, improves the application range and is conducive to improving the stability of the limited battery, and avoids the phenomenon of battery deviation.

[0035] The application sets the hole structure 1121 on the side wall of the positioning shell 110 to facilitate the battery's bar piece to extend out of the accommodating cavity through the hole structure 1121, thereby avoiding the interference between the battery's bar piece and the positioning shell 110, resulting in the phenomenon that the positioning shell 110 cannot accommodate the battery. And by setting the hole structure 1121, not only can the interference problem with the battery's bar piece be avoided, but also in the torque strength test of the battery's pole, it is conducive to improving the stability of the test and the accuracy of the test results.

[0036] The application sets the hole structure 1121 on the side wall of the positioning shell 110, which has the effect of facilitating the pre-installation of the battery when placing the battery inside the accommodating cavity, which is conducive to facilitating the positioning and placement of the battery, thereby improving the installation efficiency.

[0037] The positioning assembly 10 in the embodiment also includes a positioning top plate 120 connected with the positioning shell 110 and spaced apart along the height direction of the positioning shell 110. The positioning top plate 120 abuts against the top surface of the part of the battery exposed outside the accommodating cavity, and one of the battery's bar pieces is located in the area between the positioning top plate 120 and the positioning shell 110, to facilitate the torque strength test of the bar piece.

[0038] Specifically, the battery test fixture of the application adopts the positioning shell 110 to accommodate the battery, provides installation for the placement of the battery, and abuts against the top of the battery by the positioning top plate 120. The positioning top plate 120 and the positioning shell 110 cooperate to limit the battery in the height direction. By adjusting the position of the adjusting assembly 20, the battery is limited in the length direction and the width direction of the positioning shell 110, thereby realizing multi-directional positioning of the battery, which is conducive to improving the stability of the limited battery and avoiding the phenomenon of battery deviation.

[0039] The length direction of the base 30 is the X direction as shown, Figure 2 The width direction of the base 30 is the Y direction as shown, Figure 2 The height direction of the base 30 is the Z direction as shown, Figure 2

[0040] ​In the embodiment, the positioning top plate 120 is fixedly connected with the positioning shell 110 through bolts. Specifically, the positioning shell 110 has threaded holes matched with the bolts, and the distance between the positioning top plate 120 and the positioning shell 110 is controlled by controlling the depth of the bolts screwed into the threaded holes. The top surface of the positioning top plate 120 abuts against the battery, so the height of the positioning top plate 120 can be adjusted to be suitable for positioning batteries of different heights. The length direction and the width direction of the adjusting assembly 20 are used to limit the battery, and then the adjusting assembly 20 can be controlled to be suitable for batteries of different sizes. The battery test fixture has the characteristics of being suitable for clamping batteries of different sizes, and the application range is improved.

[0041] The positioning shell 110 and the positioning top plate 120 are independently arranged in the application, so that the pole piece fixed to the pole can be exposed, which facilitates the torque test of the pole in the later stage, and the overall structure is simple and convenient to operate.

[0042] In the embodiment, one pole piece of the battery is exposed outside the accommodating cavity for cooperating with the external test fixture to perform the torque strength test, and the other pole piece is arranged inside the positioning shell 110.

[0043] As shown in Figures 2 to 4 The positioning shell 110 includes a bottom plate 111 and a plurality of side plates 112. The bottom plate 111 is arranged on the base 30 and is used to support the battery. The plurality of side plates 112 are arranged on the bottom plate 111 and are sequentially connected in a head-to-tail manner along the circumference of the bottom plate 111. The bottom plate 111 and the plurality of side plates 112 surround to form an accommodating cavity. The positioning top plate 120 is detachably connected with the side plates 112. The adjusting assembly 20 is movably arranged on the side plates 112. At least one set of oppositely arranged side plates 112 has oppositely arranged hole structures 1121.

[0044] The bottom plate 111 is used to support the battery located inside the accommodating cavity. The plurality of side plates 112 are sequentially connected in a head-to-tail manner. The bottom plate 111 and the side plates 112 cooperate to form the positioning shell 110 with an open top. The top plate is detachably connected with the top surface of the side plate 112 through bolts. The top surface of the side plate 112 has a threaded hole. The bolt is rotationally connected through the threaded hole, so as to adjust the distance between the positioning top plate 120 and the positioning shell 110 along the height direction by rotating the bolt.

[0045] In the embodiment, the adjusting assembly 20 is arranged on the side plate 112, which facilitates the operation of the adjusting assembly 20. The structure of the plurality of side plates 112 provides a plurality of mounting positions for the installation of the adjusting assembly 20, so as to facilitate the realization of limiting the battery along the length direction and the width direction of the positioning shell 110.

[0046] The side panels 112 and the side panels 112 as well as the side panels 112 and the bottom panel 111 are detachably connected by fasteners to facilitate assembly and disassembly, wherein the fasteners are structural members such as bolts.

[0047] The present application adopts a method of setting a hole structure 1121 on at least one group of side panels 112, so that when the battery is installed in any direction, the side panels 112 have a matching hole structure 1121, which is suitable for installing batteries in various directions and sizes, and is conducive to improving the scope of use of the battery testing fixture of the present application.

[0048] In this embodiment, four side panels 112 are provided, and the bottom panel 111 and the side panels 112 cooperate to form a cubic accommodating cavity. The four side panels 112 include two groups of side panels 112, wherein one group of side panels 112 is relatively arranged along the length direction of the positioning shell 110, and the other group of side panels 112 is relatively arranged along the width direction of the positioning shell 110, and at least one of the side panels 112 in each group of side panels 112 is provided with an adjustment component 20.

[0049] Two side panels 112 are disposed opposite to each other along the length direction, and another two side panels 112 are disposed opposite to each other along the width direction. The four side panels 112 form a cubic space.

[0050] It is understandable that the two sets of side panels 112 are both provided with adjustment components 20 , and the adjustment components 20 fix the battery along the length direction and the width direction of the positioning shell 110 by pushing the battery.

[0051] In one of the specific implementations of this embodiment, an adjustment component 20 is provided on one of the two side panels 112 of each group, and the battery is pushed up by the adjustment component 20, so that one side of the battery abuts against the adjustment component 20, and the other side of the battery abuts against the side wall of the positioning shell 110, thereby fixing the battery.

[0052] Specifically, along the length direction of the positioning housing 110 , one end of the tab provided on the battery abuts against the inner surface of the positioning housing 110 , and the adjustment assembly 20 abuts against the other end of the battery.

[0053] Among them, the structure in which the inner wall surface of the positioning shell 110 is in surface-to-surface contact with the battery is beneficial to improving the stability of battery positioning. It should be noted that the position of the hole structure 1121 set on the side plate 112 is close to the position where the two side plates 112 are connected to facilitate the battery tab to extend out of the accommodating cavity.

[0054] Specifically, along the width direction of the positioning shell 110, the battery tab passes through one of the two side plates 112 and extends out of the accommodating cavity, the adjustment component 20 passes through the other side plate 112 and abuts against the battery, and the side of the battery facing away from the adjustment component 20 abuts against the inner wall surface of the positioning shell 110.

[0055] Among them, the structure in which the inner wall surface of the positioning shell 110 is in surface-to-surface contact with the battery is beneficial to improving the stability of battery positioning. It should be noted that the position of the hole structure 1121 set on the side plate 112 is close to the position where the two side plates 112 are connected to facilitate the battery tab to extend out of the accommodating cavity.

[0056] In another specific implementation of this embodiment, an adjustment assembly 20 is provided on each of the two side panels 112 of each group, and the two adjustment assemblies 20 press against both sides of the battery to fix the battery. At this time, the battery can be spaced apart from the side wall of the positioning shell 110.

[0057] In this embodiment, the battery tabs extend along the width of the positioning housing 110. Two side panels 112, positioned opposite each other along the width, are provided with hole structures 1121. Along the height of the positioning housing 110, the height of the hole structures 1121 is shorter than the height of the side panels 112. This shorter height of the hole structures 1121 improves the strength of the side panels 112.

[0058] like Figure 5 As shown, the adjustment assembly 20 includes a detachable adjustment rod 210 and a butt joint 220. The adjustment rod 210 is rotatably arranged on the positioning shell 110, and the butt joint 220 is arranged inside the accommodating cavity. The butt joint 220 is arranged at the end of the adjustment rod 210 for abutting with the battery. The adjustment rod 210 drives the butt joint 220 to move toward or away from the battery by rotation.

[0059] Among them, the movement of the abutment joint 220 is driven by adjusting the adjusting rod 210. The abutment joint 220 has an abutment surface. The abutment joint 220 abuts against the battery surface through the abutment surface. The area of ​​the abutment surface is larger than the cross-sectional area of ​​the adjusting rod 210. The abutment surface provides a larger contact surface, which is conducive to avoidance.

[0060] The present application adopts the setting of two components of the adjustment rod 210 and the abutment head 220, so as to facilitate the removal of the adjustment rod 210 and the abutment head 220 after disassembly.

[0061] In this embodiment, a threaded hole is provided on the side plate 112 of the positioning housing 110 , and an external thread is provided on the adjusting rod 210 . The adjusting rod 210 is rotatably connected to the threaded hole to adjust the extension length.

[0062] like Figure 3 and Figure 4As shown, the base 30 comprises a connecting rod 310, a mounting cylinder 320 and a positioning pin 330, the first end of the connecting rod 310 is connected with the positioning shell 110, the second end of the connecting rod 310 extends into the inside of the mounting cylinder 320, and the positioning pin 330 penetrates the mounting cylinder 320 and the connecting rod 310 and is used for positioning the mounting cylinder 320 and the connecting rod 310.

[0063] The connecting rod 310 is fixedly connected with the bottom plate 111 of the positioning shell 110, and can be connected through a structure such as a bolt.

[0064] Specifically, the structure of the base 30 of the application can be suitable for adaptive connection with positioning shells 110 of different sizes, which is beneficial to improve the application range and thus improve the experience of use.

[0065] In the embodiment, the second end of the connecting rod 310 has a first hole structure, the mounting cylinder 320 has a second hole structure, when the second end of the connecting rod 310 extends into the inside of the mounting cylinder 320, the first hole structure and the second hole structure are communicated to form a channel, the positioning pin 330 is inserted into the inside of the channel to axially and circumferentially limit the connecting rod 310 and the mounting cylinder 320, thereby realizing the stability of the overall connection and avoiding the phenomenon of misplacement and shaking.

[0066] From the above description, it can be seen that the above-mentioned embodiments of the application achieve the following technical effects:

[0067] The battery test fixture of the application accommodates the battery by using the positioning shell 110, and limits the battery by adjusting the adjusting assembly 20, which is beneficial to realize flexible positioning of the battery. The battery test fixture of the application has the characteristics of being applicable to clamping batteries of different sizes, improves the application range and is beneficial to improve the stability of the limited battery and avoid the phenomenon of battery deviation.

[0068] The application sets the hole structure 1121 on the side wall of the positioning shell 110 to facilitate the battery tab to penetrate the hole structure 1121 and extend out of the accommodation cavity, thereby avoiding the interference between the battery tab and the positioning shell 110, which causes the phenomenon that the positioning shell 110 cannot accommodate the battery. Moreover, the application sets the hole structure 1121, which not only avoids the interference problem with the battery tab, but also is beneficial to improve the stability of the test and the accuracy of the test result in the torque strength test of the battery pole.

[0069] The application sets the hole structure 1121 on the side wall of the positioning shell 110, which has the effect of facilitating the pre-installation of the battery when the battery is placed in the inside of the accommodation cavity, which is beneficial to facilitate the positioning and placement of the battery and thus improve the installation efficiency.
