Description

Technical Field

[0001] This invention relates to the field of battery testing technology, and more specifically to a quick-connection device for battery pack aging testing. Background Technology

[0002] In the production and quality inspection of battery packs, aging testing is a crucial step in evaluating their performance, consistency, and reliability. During testing, the positive and negative terminals of the aging test equipment (aging cabinet) must be reliably connected to the positive and negative terminals of the battery pack to form a closed circuit. Currently, there are two main common wiring methods: Alligator clip direct clamping: This method has a small contact area, high and unstable contact resistance, and is prone to overheating during high current testing, posing a safety hazard. It is only suitable for low current applications.

[0003] Bolt and nut locking method: This method requires overlapping of wire terminals, inserting screws and tightening with nuts. The operation is cumbersome and inefficient. In addition, it often requires wrapping with insulating tape, which consumes manpower and materials.

[0004] Existing technologies cannot guarantee the reliability of high-current connections, nor can they achieve fast and simple clamping operations or ensure safety, resulting in low testing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a quick wiring device for battery pack aging tests that is compact, easy to operate, reliable in connection, and possesses good insulation and versatility. This device is designed to enable rapid clamping and disassembly of the battery pack terminals, significantly improving testing efficiency and safety.

[0006] To address the above problems, the present invention provides the following technical solution: A quick-connection device for battery pack aging testing includes: an insulating base, and at least one conductive module disposed on the insulating base; The conductive module includes: A conductive block is fixed on the insulating base. The conductive block has a first electrical connection portion and a second electrical connection portion that are electrically connected to each other and spatially oriented in different directions. A quick-pressing mechanism is installed on the insulating base, with its pressure head facing the first electrical connection part, for pressing and fixing the battery pack's wire terminals to the first electrical connection part; The second electrical connection part is used to electrically connect the wire terminals of the test equipment.

[0007] In some embodiments, the conductive block includes a first clamping portion, a connecting portion, and a second clamping portion connected sequentially from top to bottom; the upper end surface of the first clamping portion constitutes the first electrical connection portion, and the side surface of the connecting block facing the second clamping portion constitutes the second electrical connection portion.

[0008] In some embodiments, the conductive block is a one-piece molded structure.

[0009] In some embodiments, the quick clamping mechanism is a toggle-type quick clamp or a spiral downward clamp.

[0010] In some embodiments, the pressure head of the rapid clamping mechanism is detachably connected to an extension adapter block.

[0011] In some embodiments, the extension adapter block and the pressure head are both provided with a first screw hole and a second screw hole in the coaxial direction, and the extension adapter block and the pressure head are threadedly connected.

[0012] In some embodiments, the extension adapter block is made of insulating material.

[0013] In some embodiments, the insulating base includes a base plate and a support plate disposed on the base plate, and a support block disposed on the support plate; the second electrical connection portion of the conductive block is disposed on the support block, and the support plate is provided with a through hole.

[0014] In some embodiments, the support plate, the support block, and the base plate are all made of any one of tin oxide, zinc oxide, and epoxy resin.

[0015] In some embodiments, the number of conductive modules is two, serving as a positive conductive module and a negative conductive module respectively, and symmetrically arranged on the insulating base.

[0016] The beneficial effects of this invention are: by providing a first electrical connection part and a second electrical connection part in the conductive block, the battery pack's wire terminals are pressed and fixed onto the first electrical connection part by a quick pressing mechanism, thereby connecting the battery pack's wire terminal circuit, simplifying the operation, shortening the single wiring time, improving testing efficiency, and meeting the requirements of high current and rapid clamping aging tests.

Detailed Implementation

[0019] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0022] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, this embodiment provides a quick-connection device for battery pack aging testing, which includes an insulating base 1 and at least one conductive module disposed on the insulating base 1; the conductive module includes: a conductive block 2, fixed on the insulating base 1, the conductive block 2 having a first electrical connection portion 21 and a second electrical connection portion 22 that are electrically connected to each other and spatially oriented differently; a quick-pressing mechanism 3, installed on the insulating base 1, with its pressing head 31 facing the first electrical connection portion 21, for pressing and fixing the battery pack wire terminals 4 to the first electrical connection portion 21; wherein, the second electrical connection portion 22 is used to electrically connect the wire terminals 5 of the testing equipment.

[0023] It should be noted that terminal 5 of the test equipment is the positive and negative terminal of the aging cabinet.

[0024] Analysis of the above structure reveals that the insulating base 1 and the extension adapter block 8 of the quick-clamping mechanism 3 are both made of high-strength insulating material, used to support, isolate, and clamp the conductive module, completely eliminating the risk of short circuits caused by inadequate or damaged insulating tape in traditional methods. The conductive block 2 is made of copper, and the quick-clamping mechanism 3 is a toggle-type quick clamp. By using copper blocks as the conductive medium and combining the clamping force generated by the toggle-type quick clamp, the wire terminals 5 of the test equipment do not need to be wrapped with insulating tape, saving manpower and materials, improving the clamping efficiency of positive and negative wires, and providing more reliable electrical contact.

[0025] The first electrical connection part 21 and the second electrical connection part 22 provided in the conductive block 2 are electrically connected but have different spatial orientations. The battery pack's wire terminals 4 are pressed and fixed onto the first electrical connection part 21 by the quick pressing mechanism 3, so that the battery pack's wire terminals 4 are connected in circuit. This simplifies the operation, shortens the single wiring time, improves the testing efficiency, and meets the requirements of high current and rapid clamping aging test.

[0026] like Figures 4-5 As shown, in this embodiment, the conductive block 2 includes a first clamping part 23, a connecting part 24, and a second clamping part 25 connected sequentially from top to bottom; the upper end surface of the first clamping part 23 constitutes the first electrical connection part 21, and the side of the connecting block facing the second clamping part 25 constitutes the second electrical connection part 22.

[0027] Analyzing the above structure, the first clamping part 23 has a raised cylindrical part on top and a semi-circular base on the bottom, which are connected by an arc-shaped sheet metal. The connecting part 24 is cylindrical. The second clamping part 25 has the same shape as the first clamping part 23, but the raised cylindrical part of the second clamping part 25 faces downward. The raised cylindrical part of the first clamping part 23 has a hollow center for clamping the battery pack's wire terminals 4. The raised cylindrical part of the second clamping part 25 has a hollow center for clamping the positive and negative wire terminals of the aging cabinet. When the battery pack's terminal 4 passes through one end of the first clamping part 23 and is positioned above the semi-circular base (first electrical connection part 21), the terminal is pressed firmly onto the semi-circular base by the pressing quick-clamping mechanism 3. Since the positive and negative terminals of the aging chamber (the battery pack's terminal 5) pass through the second clamping part 25 and their ends contact the connecting part 24 (second electrical connection part 22), the positive and negative terminals of the aging chamber (the battery pack's terminal 5) are electrically connected to the battery pack's terminal 4, and the test begins. When the quick-clamping mechanism 3 is pulled upwards, the battery pack's terminal 4 leaves the semi-circular base (first electrical connection part 21), and the test ends.

[0028] like Figure 7 As shown, in an optional embodiment, a plastic spring 26 is provided on the first electrical connection portion 21. When the test ends, when the quick-clamping mechanism 3 is pulled up, the plastic spring 26 will spring back the battery pack terminal 4, causing the battery pack terminal 4 to move away from the first electrical connection portion 21. Since the plastic spring 26 is not conductive, the battery pack terminal 4 is not conductive, which facilitates rapid circuit breaking and increases the safety of the test process.

[0029] like Figures 8-11As shown, in another optional embodiment, the support plate 11 is provided with a T-slot 91, and a fifth screw hole 95 is provided in the T-slot 91. The mounting surface of the quick-clamping mechanism 3 is provided with a T-shaped protrusion 92, and the quick-clamping mechanism 3 is provided with a third screw hole 93. The T-shaped protrusion 92 is provided with a fourth screw hole 95. The T-shaped protrusion 92 is slidably adapted in the T-slot 91. The third screw hole 93, the fourth screw hole 94, and the fifth screw hole 95 have the same cross-sectional radius and are all on the same axis. This facilitates the quick-clamping mechanism 3 to be quickly installed and fixed on the support plate 11. Through sliding fit, the screw holes are aligned and limited, and then manually aligned and installed with screws, making the testing process more efficient.

[0030] The hollow portion inside the first clamping part 23 can clamp the battery pack terminals 4, which have a radius larger than the hollow portion. When the battery pack terminals 4 enter the first clamping part 23, the first clamping part 23 will undergo slight expansion deformation due to the elasticity of the metal, thereby forming a clamping function. This eliminates the need for a large number of consumables such as bolts, nuts, and insulating tape, reducing tool preparation and material management steps, and lowering long-term operating costs.

[0031] like Figure 4 As shown, in this embodiment, the conductive block 2 is a one-piece molded structure.

[0032] Based on the analysis of the above structure, in this embodiment, the one-piece molding structure is beneficial to the stability of the structure.

[0033] like Figures 1-6 As shown, in this embodiment, the quick clamping mechanism 3 is a toggle-type quick clamp or a spiral downward clamp.

[0034] Based on the analysis of the above structure, the preferred quick clamping mechanism 3 is a toggle-type quick clamp.

[0035] like Figure 6 As shown, in this embodiment, an extension adapter block 8 is detachably connected to the pressure head 31 of the quick-pressing mechanism 3.

[0036] By analyzing the above structure, the extension adapter 8 is detachably connected to the pressure head 31 of the quick clamping mechanism 3. Using extension adapters 8 of different heights according to the wire terminals 4 of battery packs with different radii is beneficial to ensuring that the clamping pressure is the same.

[0037] With the design of replaceable extension adapter block 8, one set of tooling can flexibly cope with the battery pack terminals of different product models, reducing equipment investment costs.

[0038] like Figure 6 As shown, in this embodiment, the extension adapter block 8 and the pressure head 31 are respectively provided with a first screw hole 6 and a second screw hole 7 in the coaxial direction, and the extension adapter block 8 and the pressure head 31 are threadedly connected.

[0039] In this embodiment, the extension adapter block 8 is made of insulating material.

[0040] like Figures 1-3 As shown, in this embodiment, the insulating base 1 includes a base plate 14 and a support plate 11 disposed on the base plate 14, and a support block 12 disposed on the support plate 11; the second electrical connection part 22 of the conductive block 2 is disposed on the support block 12, and the support plate 11 is provided with a through hole 13.

[0041] By analyzing the above structure, the positive and negative terminals of the aging cabinet (the terminals 5 of the test equipment) are passed through the through hole 13 on the back of the support plate 11 and clamped by the second clamping part 25. When power is applied, the support plate 11 is used to prevent the current in the positive and negative terminals of the aging cabinet (the terminals 5 of the test equipment) from being too large and flowing.

[0042] like Figure 1 As shown, in this embodiment, the support plate 11, the support block 12, and the base plate 14 are all made of any one of tin oxide, zinc oxide, and epoxy resin board.

[0043] Based on the analysis of the above structure, preferably, the support plate 11, the support block 12 and the base plate 14 are made of epoxy resin board.

[0044] like Figure 1 As shown, in this embodiment, there are two conductive modules, which serve as the positive conductive module and the negative conductive module, respectively, and are symmetrically arranged on the insulating base 1.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
