Detailed implementation manners

[0023] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0025] As Figures 1 - 4 shown, a test workbench includes:

[0026] The energized fixture 100, and the number of the energized fixtures 100 is at least one;

[0027] The placement plate 200, the upper surface of the placement plate 200 is provided with a plurality of linearly arranged placement planes 201, the placement planes 201 can provide support for the energized fixture 100, and along the arrangement direction of the placement planes 201, the plurality of placement planes 201 present a gradually increasing gradient change in the vertical direction.

[0028] In this embodiment, the placement plate 200 is designed to have a plurality of linearly arranged placement planes 201, and these placement planes 201 are respectively used to support the corresponding energized fixtures 100 to ensure that each energized fixture 100 can obtain stable support; it should be noted that these placement planes 201 present a gradually increasing gradient change in the vertical direction. In this application, the batteries can be respectively placed on different placement planes 201, so that each battery has an independent operation space. Due to the height difference design of the placement planes 201, the operator can more easily access each battery and its corresponding energized fixture 100 without removing the equipment on other placement planes 201, greatly improving the work efficiency.

[0029] It should be noted that the existence of the placement planes 201 arranged in a stepped manner also helps to improve the air flow distribution in the test environment chamber, promotes the temperature to act on each battery more uniformly, and thus improves the reliability and repeatability of the test results.

[0030] Further preferably, multiple levels of gradually increasing steps are integrally provided on the placement plate 200, and the placement plane 201 is the step surface of each level of step.

[0031] In this embodiment, the formation of the placement plane 201 can have various forms. As an alternative solution, multiple elevation plates are provided on the placement plate 200, and the elevation plates are connected to the placement plate 200 through support columns with gradually increasing heights to achieve multiple levels of gradually increasing placement planes 201 on the placement plate 200; in this application, as Figure 2 shown, as an alternative solution, multiple levels of gradually increasing steps are integrally provided on the placement plate 200 to form placement planes 201 at different heights, thereby reducing the design requirements for additional components such as support columns and simplifying the structure of the entire device; moreover, the steps and the placement plate 200 form a whole, providing a more stable foundation than the support columns and reducing the risks that may be brought by the loosening or instability of the support columns.

[0032] Further preferably, the placement plate 200 is located on the workbench surface, and the placement plate 200 can slide linearly relative to the workbench surface.

[0033] In this embodiment, the placement plate 200 is designed to be able to slide linearly relative to the workbench surface. By moving the test workbench, the battery to be operated and its power-on fixture 100 can be easily moved out of the test environment chamber, greatly improving the work convenience and efficiency of the operator.

[0034] It is worth mentioning that the placement plane 201 changes in height along the linear sliding direction of the placement plate 200. When the test workbench slides out of the test environment chamber, the battery and its power-on fixture 100 will appear in front of the operator in the order of increasing height from low to high. This layout enables the operator to approach each battery more intuitively and orderly, avoiding the visual or operation blind spots caused by all the batteries being on the same plane and improving the convenience of disassembly, assembly and maintenance.

[0035] Preferably, a first connection slider 202 is provided on one of the workbench surface and the placement plate 200, and a first connection chute is provided on the other of the workbench surface and the placement plate 200, and the first connection slider 202 is slidably engaged with the first connection chute.

[0036] In this embodiment, as an alternative solution, a first connection slider 202 is provided at the bottom of the placement plate 200, and a first connection chute is provided on the workbench surface. The first connection slider 202 is slidably engaged with the first connection chute to achieve the sliding of the placement plate 200. Specifically, the first connection slider 202 is in a "convex" shape, which can effectively prevent the slider from slipping out of the chute.

[0037] Preferably, the energized fixture 100 includes two fixed clamps 101, and at least one fixed clamp 101 can slide relative to the placement plane 201, so that the distance between the two fixed clamps 101 is adjustable.

[0038] Specifically, a second connection slider 102 is provided on one of the placement plane 201 and the fixed clamp 101, and a second connection chute 203 is provided on the other of the placement plane 201 and the fixed clamp 101. The second connection slider 102 is slidably engaged with the second connection chute 203.

[0039] In this embodiment, as Figure 1 shown, as an alternative solution, the energized fixture 100 includes two fixed clamps 101 that can slide relative to the placement plane 201, so that the distance between the two fixed clamps 101 is adjustable, and the sliding manner of the placement plane 201 and the fixed clamp 101 is the same as the sliding manner of the placement plate 200 and the workbench surface.

[0040] It is worth mentioning that the second connection chute 203 on the placement plane 201 has openings at both ends, and the fixed clamp 101 can slide to the opening at the end of the second connection chute 203 and move out of the placement plane 201.

[0041] Preferably, the fixed clamp 101 includes a support plate 103 and a pressing plate 104. The support plate 103 is arranged on the placement plane 201, and the pressing plate 104 can move linearly in the vertical direction, so that the gap between the support plate 103 and the pressing plate 104 is adjustable; an energized end 108 is provided on the support plate 103.

[0042] In this embodiment, the support plate 103 is arranged on the placement plane 201 to provide a stable foundation, and an energized end 108 is provided on the support plate 103 to ensure connection with an external power supply device; the pressing plate 104 can move linearly in the vertical direction to adjust the gap between the support plate 103 and the pressing plate 104, which can adapt to batteries of different thicknesses and ensure that each battery can be firmly fixed; moreover, the pressing plate 104 and the support plate 103 can have a sufficient contact area with the tab, which can reduce the problems caused by a relatively small contact area with the tab, reduce the contact resistance, and lower the risk of local overheating, thereby improving the accuracy and reliability of the test data.

[0043] It is worth mentioning that the support plate 103 and the pressing plate 104 can be made of electrically conductive metals such as copper and aluminum, and the second connecting slider 102 is located at the bottom of the support plate 103.

[0044] Specifically, it further includes a connecting plate 105 fixedly arranged with the support plate 103. A regulating screw 106 extending along the vertical direction is screwed on the connecting plate 105. The first end of the regulating screw 106 is connected to the pressing plate 104, and the second end of the regulating screw 106 is an operating end.

[0045] In this embodiment, the first end of the regulating screw 106 is directly or indirectly connected to the pressing plate 104. By rotating the regulating screw 106, the height position of the pressing plate 104 can be changed; while the second end is the operating end, providing space for the operator to perform manual adjustment, and usually equipped with a design convenient for holding or rotating (such as a knob, a handwheel, etc.) to facilitate precise adjustment.

[0046] Further preferably, a limiting plate 107 perpendicular to the support plate 103 is fixedly arranged on the support plate 103. One end of the pressing plate 104 is in contact connection with the limiting plate 107, and the pressing plate 104 can slide relative to the limiting plate 107. The first end of the regulating screw 106 is rotatably connected to the pressing plate 104.

[0047] In this embodiment, the contact connection between the limiting plate 107 and the pressing plate 104 provides a clear and restricted movement path for the pressing plate 104, ensuring that it can only move in the vertical direction, which greatly reduces the possibility of any lateral offset or swing, making the entire clamping process more stable; and the operator only needs to focus on rotating the regulating screw 106 without worrying about whether the pressing plate 104 will deviate from the predetermined track, thus improving work efficiency.

[0048] It is worth mentioning that the limiting plate 107 also serves as a connecting piece to fixedly connect the support plate 103 and the connecting plate 105.

[0049] A test environment chamber includes the above-mentioned test workbench.
