[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0049] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0050] As mentioned in the background section, in order to solve the technical problem that welding the electrode connection bar in the battery test experiment in the prior art leads to the scrapping of the battery after the experiment, this application provides a welding-free test fixture device that is compatible with various battery sizes. It can achieve the technical effect of using the probe 4 to press the battery electrode instead of welding the electrode, thereby avoiding battery damage after the experiment.

[0051] This application provides a solderless test fixture device adaptable to various battery sizes, comprising:

[0052] Adjustable bracket 1, which is used to provide and adjust the space for placing the battery 6 to be tested;

[0053] Fixing component 2, two fixing components 2 are distributed along the first direction and inserted into the adjustable bracket 1 along the second direction. The fixing components 2 are symmetrically provided with hooks 3 on both sides along the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0054] Probe 4 is mounted on the fixed component 2 along the second direction, and the terminals of probe 4 are used to connect to the test circuit.

[0055] The quick clips 5 are respectively located on the adjustable bracket 1 and correspond to the hooks 3. The quick clips 5 are used to fasten and fix with the hooks 3 so that the spring end of the probe 4 is pressed against the electrode of the battery 6 under test in the accommodating space and electrically connected to the battery 6 under test.

[0056] like Figure 1-4As shown, the device provided in this embodiment is applied to lithium titanate and lithium iron phosphate batteries with a cuboid structure. The first direction is the length direction of the battery 6 to be tested, the second direction is the height direction of the battery 6 to be tested, and the third direction is the width direction of the battery 6 to be tested. The adjustable bracket 1 is approximately a frame structure, on which a receiving space for setting the battery 6 to be tested is formed. Two fixing components 2 are inserted into the top of the adjustable bracket 1, located above the receiving space. The probe 4 is fixed on the fixing component 2. The wiring end of the probe 4 passes through the fixing component 2 along the second direction and is connected to the test circuit through the lead wire. The spring end below the probe 4 contacts the electrode of the battery 6 to be tested in the receiving space, so that the battery 6 to be tested is electrically connected to the test circuit. Hook There are four hooks 3 and four quick clips 5. The four hooks 3 are divided into two groups of two. The two hooks 3 in each group are threadedly connected to the two sides of the fixing component 2 along the third direction by fixing bolts. The four quick clips 5 correspond one-to-one with the hooks 3. The quick clip 5 includes a base, which is fixed on the adjustable bracket 1. The base is threaded with a ring. Rotating the ring can adjust its relative position with the base so that the ring can better cooperate with the hook. By pressing the handle on the base, the ring can be engaged with the hook 3, thereby causing the two fixing components 2 to abut against the adjustable bracket 1. The two probes 4 press the positive electrode and negative electrode of the battery to be tested 6 respectively, so as to realize the electrical connection of the battery to be tested 6 to the test circuit in a non-welding manner.

[0057] An adjustable bracket 1 is used to accommodate the battery 6 to be tested. Two fixing components 2 are inserted into the adjustable bracket 1. The probes 4 on the fixing components 2 can abut against the electrodes of the battery 6 to make the battery 6 to be tested electrically connected to the test circuit. This replaces the method of welding the connection bar to the electrodes of the battery 6 to conduct the experiment. No professional personnel are required to operate welding equipment to perform additional welding work, saving manpower, material resources and time costs. Moreover, the connection method of the probes 4 will not damage the appearance of the battery 6 to be tested. After the experiment, the batteries that pass all performance tests can be downgraded to B-grade batteries or used for pack trial production verification and other tiered batteries for reuse, saving battery costs and being more environmentally friendly. At the same time, the adjustable bracket 1 and the fixing components 2 are fixed by the quick clamp 5 and the hook 3 to ensure that the spring end of the probe 4 is pressed tightly against the electrode of the battery 6 to be tested, avoiding poor contact between the electrode and the probe 4 during the experiment. The quick clamp 5 fixing method can be completed by a single person, which is convenient and quick, and greatly improves the assembly efficiency.

[0058] In a preferred embodiment, the adjustable support 1 includes:

[0059] The first adjusting block 11, two first adjusting blocks 11 are distributed along the first direction and are connected together by the guide rod 14;

[0060] The adjustment components are divided into two groups of four, with two components in each group. The two groups of adjustment components are respectively located on the two first adjustment blocks 11, and each adjustment component is fixed with a quick clamp 5.

[0061] like Figure 1 As shown, the first adjustment block 11 is approximately a cuboid block structure and extends along a third direction. Two first adjustment blocks 11 are arranged along a first direction. There are two guide rods 14, which pass through the two first adjustment blocks 11 in sequence, allowing the two first adjustment blocks 11 to slide relative to the guide rods 14, thereby changing the relative distance between the two first adjustment blocks 11. The first adjustment blocks 11 are used to support the battery 6 to be tested. By sliding the two first adjustment blocks 11, the relative distance between them is changed, so that the adjustable bracket 1 can support batteries 6 of different lengths to be tested. Each first adjustment block 11 is provided with a set of adjustment components. Each set of two adjustment components is arranged on the first adjustment block 11 along a third direction, which are used to clamp the battery 6 to be tested on both sides of the width direction of the battery 6 to be tested, so as to prevent the battery 6 to be tested from shaking during the experiment and affecting the test results.

[0062] In a preferred embodiment, the adjustment component includes:

[0063] The second adjusting block 12 is disposed on the first adjusting block 11. The second adjusting block 12 has a first through groove 121 extending along the second direction and a second strip hole 122. The second strip hole 122 communicates with the first through groove 121.

[0064] The third adjusting block 13 is slidably disposed in the first through groove 121. The third adjusting block 13 has a plurality of first threaded holes 131 opened along the second direction. After the first bolt passes through the second strip hole 122, it is threadedly connected to one of the first threaded holes 131 so that the third adjusting block 13 is relatively fixed to the second adjusting block 12.

[0065] like Figure 1 , Figure 6 and Figure 7As shown, there are four second adjusting blocks 12 and four third adjusting blocks 13. The two first adjusting blocks 11, the four second adjusting blocks 12, and the four third adjusting blocks 13 together form the aforementioned accommodating space. The two second adjusting blocks 12 are disposed on the first adjusting blocks 11 along the third direction, located on both sides of the width direction of the battery 6 to be tested. The first through groove 121 is opened on the side of the second adjusting block 12 near the battery 6 to be tested. The third adjusting block 13 is also approximately a cuboid block structure. The inner contour of the first through groove 121 matches the outer contour of the third adjusting block 13. The third adjusting block 13 can be embedded in the first through groove 121 and slide along the first through groove 121. The two ends of the fixing component 2 along the third direction are respectively inserted into the same first... The tops of the two third adjustment blocks 13 on the adjustment block 11 are equipped with quick clamps 5 and corresponding hooks 3. The third adjustment block 13 can be slid along the first through groove 121 to accommodate batteries 6 of different heights to be tested. The second strip hole 122 is opened on one side of the second adjustment block 12 along the first direction. Multiple first threaded holes 131 are opened corresponding to the second strip hole 122. When the third adjustment block 13 slides in the first through groove 121, at least one first threaded hole 131 is connected to the second strip hole 122. After the first bolt passes through the second strip hole 122, it is threaded to the corresponding first threaded hole 131, so that the second adjustment block 12 and the third adjustment block 13 can be fixed relative to each other.

[0066] In a preferred embodiment, the fixing component 2 includes:

[0067] Fixing block 21, on which probe 4 is fixed;

[0068] Positioning blocks 22, two positioning blocks 22 are respectively located on both sides of the fixing block 21 along the third direction, and hooks 3 are fixed on the positioning blocks 22;

[0069] Slide rod 23 passes through fixed block 21 and two positioning blocks 22 in a third direction;

[0070] The positioning block 22 is inserted into the corresponding adjustment component, and the adjustment component is slidably connected to the first adjustment block 11 along the third direction.

[0071] like Figure 8 and Figure 9As shown, both the fixing block 21 and the positioning block 22 are cuboid structures. The fixing block 21 has a first mounting hole. The probe 4 passes through the first mounting hole and is threaded to the fixing block 21 through a set screw. The two positioning blocks 22 are located on both sides of the fixing block 21 along a third direction. Hooks 3 are provided on the side of the two positioning blocks 22 that are far apart from each other. The hooks 3 are also threaded to the positioning blocks 22 through fixing bolts. There are four sliding rods 23. Each fixing component 2 includes two sliding rods 23. The sliding rods 23 pass through one positioning block 22, the fixing block 21 and the other positioning block 22 in sequence along a third direction, so that the two positioning blocks 22 can slide relative to the fixing block 21 along a third direction. The positioning block 22 has a first positioning hole 221 with an internal thread. The top of the third adjusting block 13 is aligned with the first positioning hole 221. The first positioning hole 221 is provided with a second positioning hole 133, and a positioning post is also provided. The upper half of the positioning post is threaded and the lower half is hollow. By passing the positioning post through the first positioning hole 221 and the second positioning hole 133 in sequence, the upper half of the positioning post is threaded into the first positioning hole 221 and the lower half is inserted into the second positioning hole 133. This allows the positioning block 22 and the third adjusting block 13 to be fixed relative to each other in the first and third directions. Since the second adjusting block 12 can slide on the first adjusting block 11 along the third direction, the adjustable bracket 1 can accommodate batteries 6 of different widths to be tested. During this process, the positioning block 22 inserted into the third adjusting block 13 can move with the third adjusting block 13, while the fixing block 21 can be kept in the initial position so that the probe 4 is pressed against the electrode of the battery 6 to be tested.

[0072] In a preferred embodiment,

[0073] The first adjusting block 11 has at least two first strip holes 111 extending in a third direction;

[0074] The adjustment assembly has at least one second through hole 123. At least one third bolt 101 passes through the first strip hole 111 and the second through hole 123 in sequence and is threaded to the nut 102 so that the first adjustment block 11 is fixed relative to the adjustment assembly.

[0075] like Figure 1 , Figure 5 and Figure 6As shown, each first adjusting block 11 has four first strip holes 111. The four first strip holes 111 are divided into two groups, with two first strip holes 111 in each group. Each group of first strip holes 111 is used to connect a second adjusting block 12. Each second adjusting block 12 has two second through holes 123 at its bottom. The second through holes 123 correspond to the first strip holes 111. The third bolt 101 passes through the first strip holes 111 and the second through holes 123 in sequence, so that the second adjusting block 12 can slide on the first adjusting block 11 in a third direction, thereby realizing the width adjustment of the adjustable bracket 1. By tightening the nut 102 on the third bolt 101, the first adjusting block 11 and the third adjusting block 13 can be fixed relative to each other.

[0076] In a preferred embodiment, the fixing block 21 is fixed to the middle of the slide bar 23.

[0077] like Figure 9 As shown, the fixing block 21 has second mounting holes on both sides of the first mounting hole along the first direction, and the slide rod 23 has a third threaded hole in the middle. The fixing block 21 is fixed in the middle position of the two slide rods 23 by threading the nut screw through the first mounting hole and connecting it to the third threaded hole. This prevents the fixing block 21 from shifting position when the width of the adjustable bracket 1 is adjusted, as the positioning block 22, which moves with the third adjusting block 13, slides on the slide rod 23, causing the probe 4 to be inaccurately positioned or deviate from its position.

[0078] In a preferred embodiment,

[0079] At least one first through hole 112 is provided on the first adjusting block 11, and a linear bearing 15 is provided in the first through hole 112;

[0080] At least one guide rod 14 passes through two linear bearings 15 in sequence and is slidably connected to the linear bearings 15.

[0081] like Figure 1 As shown, there are four linear bearings 15. Each first adjusting block 11 has two first through holes 112. The four linear bearings 15 are respectively embedded in the first through holes 112. The guide rod 14 passes through the two first adjusting blocks 11 sequentially from the linear bearings 15. By setting the linear bearings 15 that cooperate with the guide rod 14 on the first adjusting block 11, the first adjusting block 11 can move linearly in the first direction stably, preventing the first adjusting block 11 from deviating or shaking during sliding. At the same time, it greatly reduces the frictional resistance between the first adjusting block 11 and the guide rod 14 when sliding, making it more convenient to adjust the length of the adjustable bracket 1.

[0082] In a preferred embodiment,

[0083] The second adjusting block 12 has a groove 124 extending in the second direction;

[0084] The third adjusting block 13 has multiple second threaded holes 132 along the second direction. The second bolt passes through the quick clamp 5 and the groove 124 in sequence and is threaded to one of the second threaded holes 132 so that the quick clamp 5 is fixed relative to the third adjusting block 13.

[0085] like Figure 6 and Figure 7 As shown, the second threaded hole 132 is used to install the quick clamp 5. After the second bolt passes through the base of the quick clamp 5, it is threaded into the second threaded hole 132, which can fix the quick clamp 5 on the third adjusting block 13. Multiple second threaded holes 132 are provided to adjust the specific installation position of the quick clamp 5 on the third adjusting block 13 when installing the quick clamp 5, so that it can better cooperate with the hook 3 on the positioning block 22. The groove 124 extends upward from the second adjusting block 12 along the second direction and passes through the top of the second adjusting block 12 to prevent the connection structure between the third adjusting block 13 and the quick clamp 5 from interfering with the second adjusting block 12 when adjusting the height of the adjustable bracket 1.

[0086] In a preferred embodiment, the two ends of the guide rod 14 are respectively fixed with a first limiting bolt 141, and the two ends of the slide rod 23 are respectively fixed with a second limiting bolt 231.

[0087] like Figure 1 and Figure 8 As shown, there are four first limiting bolts 141, with two first limiting bolts 141 on each guide rod 14. During installation, the first limiting bolt 141 at one end of the guide rod 14 is removed, and this end of the guide rod 14 is passed sequentially through the linear bearings 15 on the two first adjusting blocks 11. Then, the first limiting bolts 141 are reinstalled. The two first limiting bolts 141 are used to limit the first adjusting blocks 11 when they slide relative to the guide rod 14 in the first direction, preventing the first adjusting blocks 11 from dislodging from the guide rod 14 during the sliding process. There are eight second limiting bolts 231. Each slide rod 23 is provided with two first limiting bolts 141. During installation, the second limiting bolt 231 at one end of the slide rod 23 is removed, and the slide rod 23 is passed through one of the positioning blocks 22, the fixing block 21 and the other positioning block 22 in sequence. Then, the second limiting bolt 231 is reinstalled. The two second limiting bolts 231 are used to limit the positioning blocks 22 when the two positioning blocks 22 slide relative to the slide rod 23 in a third direction, so as to prevent the positioning blocks 22 from falling off the slide rod 23 during the sliding process.

[0088] In a preferred embodiment, both the first adjusting block 11 and the third adjusting block 13 are made of rubber, and the fixing component 2 is provided with a rubber pad.

[0089] like Figure 5 , Figure 7 and Figure 8 As shown, two first adjusting blocks 11 are used to support the battery 6 to be tested, and four third adjusting blocks 13 are divided into two groups. The two third adjusting blocks 13 in each group are clamped by the battery 6 to be tested along the third direction on both sides. By using fluororubber material to make the first adjusting blocks 11 and the third adjusting blocks 13, the structures that are in contact with the battery 6 to be tested between the adjustable blocks have insulation properties, which meets the insulation requirements of the test fixture for the battery 6 to be tested. The rubber pads include first rubber pads 24 and second rubber pads 25. There are two first rubber pads 24 and four second rubber pads 25. The first rubber pads 24 have a third through hole in the middle and are attached to the top of the fixing block 21. The third through hole is used for the probe 4 to pass through and connect to the test circuit. The second rubber pads 25 are attached to the top of the positioning block 22.

[0090] Working principle: In use, the battery to be tested 6 is placed on two first adjusting blocks 11, and positioned between the two adjusting components on each first adjusting block 11. According to the length of the battery to be tested 6, the two first adjusting blocks 11 are slid along the first direction to adapt their relative positions to the length of the battery to be tested 6. According to the width of the battery to be tested 6, the four second adjusting blocks 12 are slid along the third direction to allow the four third adjusting blocks 13 to abut against both sides of the width of the battery to be tested 6. The nuts 102 on the third bolt 101 are tightened to fix the relative positions of the second adjusting blocks 12 and the first adjusting blocks 11. According to the height of the battery to be tested 6, the four third adjusting blocks 13 are slid along the second direction to align the top of the third adjusting blocks 13 with the height of the battery to be tested 6.
