[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Example 1, as Figures 1-2 As shown, a power battery testing device includes a housing 1. A support frame 2 for receiving products is movably disposed in the cavity of the housing 1. The support frame 2 can move longitudinally relative to the housing 1. The housing 1 is provided with a lower cavity 102 and an upper cavity 101. The lower cavity 102 contains liquid, and the upper cavity 101 is longitudinally connected to the lower cavity 102.

[0023] The top of the aforementioned housing 1 is provided with a connecting frame 3 that connects to the support frame 2, and the outer side of the housing 1 is provided with a drive unit 4 for driving the connecting frame 3 to move up and down. For example... Figure 4 , Figure 7 , Figure 9 and Figure 10 As shown, the aforementioned connecting frame 3 includes a support frame 303, a first connecting rod 301 connected to the support frame 303 and passing through the housing 1 and connecting to the support frame 2, and a second connecting rod 302 connected to the support frame 303 and connected to the drive unit 4. That is, one end of the first connecting rod 301 is connected to the support frame 303, and the other end of the first connecting rod 301 is movably inserted into the housing 1 and connected to the support frame 2 inside the housing 1; one end of the second connecting rod 302 is connected to the support frame 303, and the other end of the second connecting rod 302 is connected to the drive unit 4.

[0024] The drive unit 4 drives the support frame 2 to move up and down within the housing 1 via the connecting frame 3, enabling multi-environment switching testing of the product and improving the efficiency of product testing. Furthermore, in this embodiment, both the support frame 303 and the connecting frame 3 are welded from stainless steel square tubing. Stainless steel square tubing offers high connection strength and structural stability, meeting the structural rigidity requirements of the device; it also possesses excellent corrosion resistance. The drive unit 4 can handle testing products weighing tons, improving the stability of the testing device. When testing in liquids, the support frame 2 and connecting frame 3 are corrosion-resistant and suitable for different liquids, improving the applicability and service life of the device.

[0025] Furthermore, such as Figure 10As shown, a bakelite board 201 is provided on the side of the support frame 2 opposite to the lower cavity 102, and the bakelite board 201 is provided with a plurality of through holes 202. Specifically, the through holes 202 are spaced apart to allow the support frame 2 to drain liquid quickly, improve structural stability and device safety, and prevent product leakage during the testing process, which could cause injury to the staff.

[0026] In addition, such as Figure 8 As shown, the lower end of the first connecting rod 301 passes through the support frame 2 and is equipped with a guide wheel 12 at its end. The inner wall of the housing 1 is provided with a guide rail 13 corresponding to the guide wheel 12, which ensures the stability of the support frame 2 during lifting and lowering and improves the accuracy of product testing. Specifically, during testing, the support frame 2 moves up and down, driving the guide wheel 12 to roll within the guide rail 13, thereby improving the stability of the support frame 2 during up and down movement.

[0027] Example 2: This example provides a power battery testing device. This example is an optimization based on Example 1 to improve the technical effect and refine the technical solution. For details not described in this example, please refer to Example 1. This example describes the specific structure of the drive unit 4.

[0028] like Figures 1-2 As shown, drive units 4 are symmetrically arranged on both sides of the housing 1. The two drive units 4 are synchronously driven by a motor 5 located on the outside of the housing 1. The drive units 4 are located in the side boxes on both sides of the housing 1.

[0029] like Figures 4-6 As shown, the drive unit 4 includes a first sprocket 401, a chain 402, and a second sprocket 403. The first sprocket 401 is connected to the housing 1, and the first sprocket 401 is connected to the second sprocket 403 via the chain 402. The second sprocket 403 is driven by a motor 5. The chain 402 is connected to a support rod 7 via a fixed base 6, and a second connecting rod 302 is connected to the support rod 7. The first sprocket 401 is connected to the side housing via the first connecting rod 301. The first sprocket 401 is configured with... The protrusion on the first sprocket 401 engages with the groove on the first connecting rod 301, thereby fixing it to the first connecting rod 301. During the lifting process, the first connecting rod 301 rotates relative to the side box. The second sprocket 403 engages with the groove on the second connecting rod 302 through the protrusion on the second sprocket 403, thereby fixing it to the second connecting rod 302. The second connecting rod 302 passes through the side box and connects to the right-angle steering gear, which is connected to the output shaft of the motor 5.

[0030] Specifically, motor 5 drives the second sprocket 403 to rotate, and the second sprocket 403 drives the first sprocket 401 to rotate through the chain 402. The supporting rod 7 on the chain 402 moves up and down, thereby controlling the second connecting rod 302, so that the support frame 2 can move up and down within the housing 1 and improve the stability of the support frame 2's movement. Motor 5 is a high-inertia servo motor with a reducer, which can meet the requirements for testing products weighing tons.

[0031] Furthermore, the receiving rod 7 is equipped with a slider 701, which is slidably connected to the slide rail 702 on the housing 1, as detailed below. Figure 3 As shown, sliders 701 are provided at both ends of the receiving rod 7; this can improve the stability of the receiving rod 7 as it moves up and down with the chain 402.

[0032] Example 3: This example provides a power battery testing device. This example is an optimization based on Example 2 to improve the technical effect and refine the technical solution. For details not described in this example, please refer to Example 2. In order to make the receiving rod 7 and the chain 402 stably connected and improve the stability during the indirect process, a fixing seat 6 is provided between the receiving rod 7 and the chain 402. This example describes the specific structure of the fixing seat 6.

[0033] like Figures 11-12 As shown, the fixing base 6 includes a body 601 connected to the receiving rod 7 and a fixing post 602 provided on the body 601. The fixing post 602 passes through the gap between two links of the chain 402.

[0034] Specifically, the fixing post 602 is located in the gap between the two links of the chain 402, which ensures that it will not fall off when the chain 402 moves, thus ensuring the stability of the drive unit 4.

[0035] Example 4: This example provides a power battery testing device. This example is an optimization based on Example 1 to improve the technical effect and refine the technical solution. For details not described in this example, please refer to Example 1. This example describes how the housing 1 controls the ambient temperature and liquid temperature. like Figure 4 and Figure 7 As shown, the upper cavity 101 is a temperature-controlled environment chamber. A second motor 8 is installed on the outside of the temperature-controlled environment chamber, and a ventilation plate 9 is installed on the inner wall of the chamber. A heating module connected to the second motor 8 is installed in the cavity formed by the ventilation plate 9 and the inner wall of the temperature-controlled environment chamber. The heating module in this embodiment uses a product from the prior art; the specific product model will not be described in detail here, as long as it can basically achieve the desired function in this embodiment.

[0036] The lower cavity 102 is a temperature-controlled liquid tank. A pipe 10 is installed inside the temperature-controlled liquid tank, and the pipe 10 is connected to a chiller 11 used to regulate the temperature of the liquid inside the temperature-controlled liquid tank.

[0037] Specifically, the temperature-controlled environment chamber and the temperature-controlled liquid chamber are composed of a stainless steel square tube welded support frame and a stainless steel plate welded chamber body. By placing the temperature-controlled environment chamber on the temperature-controlled liquid chamber, and connecting the temperature-controlled liquid chamber to the chiller 11 that controls the liquid temperature, the temperature-controlled environment chamber controls the ambient temperature. This allows the product to freely choose the testing scenario within the two chambers 1, saving product testing steps and improving product testing efficiency.

[0038] Furthermore, such as Figure 4 As shown, the bottom of the temperature-controlled liquid tank is provided with a drain pipe 105, which is connected to an overflow pipe 106, and the overflow pipe 106 is connected to the top of the temperature-controlled liquid tank.

[0039] Specifically, when the temperature control liquid tank needs to be drained, the drain pipe 105 can help the temperature control liquid tank drain the liquid inside the temperature control liquid tank to the outside of the temperature control liquid tank. When the liquid inside the temperature control liquid tank is too full, the excess liquid inside the temperature control liquid tank can be guided to the drain pipe 105 through the overflow pipe 106 and then discharged through the drain pipe 105.

[0040] Example 5: This example provides a power battery testing device. This example is an optimization based on Example 1 to improve the technical effect and refine the technical solution. For details not described in this example, please refer to Example 1. In order to enable product testing for a long time, this example provides thermal insulation material 104 on the housing 1.

[0041] like Figure 9 As shown, a steel plate 103 for sealing is provided on the outside of the box 1, and a thermal insulation material 104 is provided between the steel plate 103 and the box 1. Specifically, in this embodiment, the thermal insulation material 104 is polyurethane foam and rock wool, and the thermal insulation material 104 covers the steel plate 103 on the outside to achieve the effect of thermal insulation.

[0042] Example 6: Based on any of Examples 1 to 5, the enclosure 1 further includes an operating support frame 2, an operating platform for product testing, a ladder, a door lock, and an observation window. The operating platform is equipped with a monitor, a touch screen, and a control cabinet. The ladder, door lock, and observation window are for the convenience of staff to observe the testing process and prevent unexpected events. In this example, the monitor, touch screen, and control cabinet use existing products; specific product models will not be detailed here, as long as they can basically achieve the functions required in this example. The control connections between the monitor, touch screen, and control cabinet also use conventional connection methods from the prior art; specific connection circuits will not be detailed here, as long as they can basically achieve the functions required in this example.

[0043] Working principle: The product to be tested is placed on the support frame 2. The operator operates the operating platform and sets the lifting height of the support frame 2 as needed. The liquid temperature in the temperature-controlled liquid tank and the ambient temperature in the temperature-controlled environment chamber are adjusted to the required temperature. The product testing begins. At this time, the motor 5 rotates, which drives the second connecting rod 302 to rotate through the right-angle steering gear. This drives the second sprocket 403 and the first sprocket 401 to rotate. The chain 402 drives the support frame 2 to move up and down to test the product.

[0044] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
