[0022] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0023] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0024] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0025] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0026] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0027] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation.

[0031] This utility model provides a battery testing fixture, such as Figures 1 to 3 As shown, the battery testing fixture includes a fixture body 1, a cover plate 2, and a telescopic rod 3.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the aforementioned components of the battery test fixture and their connection relationships are described in detail.

[0033] like Figures 1 to 3As shown in the embodiment, the clamp body 1 can be provided with multiple battery mounting slots 10, which are used to hold hexagonal batteries. Multiple cover plates 2 can be provided, and each cover plate 2 can be positioned above a multiple battery mounting slot 10. A telescopic rod 3 connects the cover plate 2 to the clamp body 1. The telescopic rod 3 can extend and retract vertically. When the telescopic rod 3 extends, the operator can place the hexagonal battery into the battery mounting slot 10 below the cover plate 2 for quick installation. When the telescopic rod 3 retracts, the cover plate 2 can press the hexagonal battery firmly into the battery mounting slot 10 to accommodate individual battery cells of different sizes. This avoids spending a lot of time installing hexagonal batteries and eliminates the need to develop multiple clamps for different individual battery cell sizes.

[0034] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the clamp body 1 can be formed as a strip. Preferably, the clamp body 1 can be a rectangular plate, and the battery mounting slot 10 can be formed on the upper surface of the clamp body 1. There are multiple battery mounting slots 10; specifically, as described in this embodiment, there can be five. The multiple battery mounting slots 10 can be spaced apart along the length of the clamp body 1. More preferably, the distance between adjacent battery mounting slots 10 can be equal. Furthermore, the clamp body 1 can be made of PC / ABS plastic material (a thermoplastic plastic made of polycarbonate and polyacrylonitrile alloy) with good insulation properties and flame retardancy.

[0035] Furthermore, preferably, such as Figures 1 to 3 As shown, in this embodiment, the battery mounting groove 10 can be a strip-shaped groove. The length direction of the battery mounting groove 10 can be perpendicular to the length direction of the clamp body 1. The battery mounting groove 10 connects the two ends in the width direction of the clamp body 1. Preferably, the cross-section of the battery mounting groove 10 can be trapezoidal. Specifically, as shown... Figure 3 As shown, the width of the bottom of the battery mounting slot 10 can be smaller than the width of the opening. This design makes it easier to place a hexagonal battery into the battery mounting slot 10, and the trapezoidal shape of the battery mounting slot 10 is more suitable for the shape of the hexagonal battery, allowing the hexagonal battery to be installed more securely in the battery mounting slot 10.

[0036] Preferred, such as Figures 1 to 3As shown, in this embodiment, the cover plate 2 can be a rectangular plate. The length direction of the cover plate 2 can be parallel to the length direction of the battery mounting groove 10, and the cover plate 2 can be positioned directly above the battery mounting groove 10 to better fix the hexagonal battery. Preferably, the cover plate 2 can be positioned parallel to the bottom surface of the battery mounting groove 10, the width of the cover plate 2 can be smaller than the width of the battery mounting groove 10, and the length of the cover plate 2 can be smaller than the length of the battery mounting groove 10.

[0037] Further optimized, such as Figures 1 to 3 As shown, in this embodiment, the cover plate 2 may have side plates 21 on both sides in the width direction. The side plates 21 can be rectangular plates. Preferably, the side plates 21 can be inclined. Specifically, the side plates 21 can be inclined from top to bottom away from the cover plate 2, so that the two side plates 21 and the cover plate 2 form a trapezoidal space to match the shape of the battery mounting slot 10. This allows the cover plate 2 and side plates 21 to effectively fix the upper part of the hexagonal battery after it is installed in the battery mounting slot 10.

[0038] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the side plates 21 disposed on both sides of the same cover plate 2 can be connected by a horizontal plate 22. Specifically, the horizontal plate 22 can be a rectangular plate, and its length can be equal to the width of the cover plate 2. The horizontal plate 22 can be disposed in the middle of the cover plate 2 along its width direction, and the horizontal plate 22 can be fixed to the cover plate 2 by snap-fit ​​or welding. The upper ends of the two side plates 21 can be connected to the two ends of the horizontal plate 22 along its length direction, respectively. Preferably, the two side plates 21 can be integrally formed with the horizontal plate 22, and the included angles between the two side plates 21 and the horizontal plate 22 can be equal.

[0039] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the bottom end of the telescopic rod 3 can be fixed to the clamp body 1. Specifically, the clamp body 1 can be provided with a threaded hole with internal threads, and the bottom end of the telescopic rod 3 can be provided with external threads, so that the telescopic rod 3 can be threadedly connected to the clamp body 1. The top end of the telescopic rod 3 can be connected to the bottom end of the side plate 21 (either by snap-fit ​​or by threaded connection). Preferably, each side plate 21 can be provided with two telescopic rods 3 at its bottom end. The two telescopic rods 3 can be spaced apart in the width direction of the clamp body 1. The telescopic rod 3 can be a multi-layered rod (similar to a suitcase handle), and a snap-fit ​​structure can be provided inside the telescopic rod 3, so that the telescopic rod 3 can be snapped and fixed after extending to a preset length to fix the cover plate 2, thereby making it easier for the operator to put the hexagonal battery into the lower part of the cover plate 2.

[0040] In a further preferred embodiment, a magnetic element may be embedded at the bottom of the cover plate 2, and a corresponding magnetic element may be embedded in the battery mounting slot 10. The magnetic element at the bottom of the cover plate 2 may be positioned corresponding to the magnetic element in the battery mounting slot 10, causing the cover plate 2 to tend to move downwards under the influence of magnetic force. When an operator places a hexagonal battery into the battery mounting slot 10, the cover plate 2, under the influence of magnetic force, can press the hexagonal battery downwards to prevent the hexagonal battery from shifting.

[0041] In addition, preferred, such as Figures 1 to 3 As shown, in this embodiment, pivotable baffles 23 can be provided at both ends of the cover plate 2 along its length. The baffles 23 can be rectangular plates. The long side of the baffle 23 can be hinged to the end of the cover plate 2 along its length, allowing the operator to lift or lower the baffle 23. Preferably, a snap-fit ​​structure can also be provided at the bottom of the cover plate 2. When the baffle 23 is pivoted downwards to be perpendicular to the cover plate 2, the baffle 23 snaps into the cover plate 2, allowing the two baffles 23 to fix the hexagonal battery to the lower part of the cover plate 2.

[0042] Further optimized, such as Figures 1 to 3 As shown, in this embodiment, the baffle 23 can be a metal plate to facilitate electrical conductivity. A connecting nut 231 can be welded to the center of the baffle 23, such as... Figure 1 As shown, the connecting nut 231 can be positioned on the side of the baffle 23 away from the hexagonal battery. When the baffle 23 is pivoted to be perpendicular to the cover plate 2, the baffle 23 can contact the positive or negative terminal of the hexagonal battery, making the connecting nut 231 electrically connected to the hexagonal battery. At this time, the operator can connect the positive and negative wires to the connecting nut 231 to test the hexagonal battery.

[0043] During use, the operator can place the battery testing fixture into the test environment chamber. First, place the fixture body 1 flat on the surface of the test environment chamber and fix it in place. Then, pull up the cover plate 2 to extend the telescopic rod 3. After flipping the baffle 23 upward, place the hexagonal battery into the battery mounting slot 10 and adjust its position. Then, lower the cover plate 2 so that it presses down on the upper part of the hexagonal battery, and flip the baffle 23 downward until it is fixed. Finally, connect the positive and negative wires to the two connecting nuts 231 respectively to begin the test.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
