Description

Technical Field

[0001] This utility model relates to the field of automotive component testing technology, specifically a placement rack for low-temperature testing of automotive batteries. Background Technology

[0002] Low temperatures increase the viscosity of the electrolyte in a battery and slow down ion conduction, leading to increased internal resistance and capacity decay. This severely impacts the cold-start performance of vehicles and the stability of electronic equipment power supply. To gain a deeper understanding of the performance changes of automotive batteries at low temperatures, and thus optimize battery performance and improve the vehicle's adaptability to low-temperature environments, low-temperature testing is essential. During transport, batteries on the mounting rack are prone to shaking and displacement, interfering with test results. Mounting racks made of ordinary materials experience a decline in mechanical properties at low temperatures, becoming brittle and deformed, leading to structural instability. Furthermore, their lack of insulation means that if a battery is damaged during testing and leaks current, it can easily affect other batteries. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a placement rack for low-temperature testing of automotive batteries, comprising a primary base and a secondary base.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-5 This utility model provides a placement rack for low-temperature testing of automotive batteries, including a primary base 1 and a secondary base 6. Each of the four corners of the bottom of the primary base 1 is fixedly equipped with a caster wheel 2. A handle 3 is fixedly installed on one side of the primary base 1. Vertical support rods 4 are fixedly installed at the four corners of the top of the primary base 1 and the four corners of the top of the secondary base 6. A support frame 5 is fixedly installed at the top between the four vertical support rods 4. A rotating groove 11 is opened in the middle of the two opposing vertical support rods 4. A limiting device is threaded into the inner cavity of the rotating groove 11. The limiting device includes a rotating wheel 12. A bidirectional lead screw 13 is fixedly connected to one end of the rotating wheel 12. A limiting ring 14 is fixedly installed at one end of the bidirectional lead screw 13. Two limiting plates 15 are threadedly connected to the outer ring of the middle of the bidirectional lead screw 13. A sliding rod 20 is provided at the other end between the limiting plates 15. The vertical support rods 4 and the support frame 5 are both made of aluminum alloy, and the insulating protective layer 9 is made of polytetrafluoroethylene.

[0019] In this embodiment of the application, the integrity of the insulating protective layer 9, the vertical support rod 4, and the support frame 5 is first checked. Then, the limiting frame 10 is placed into the first snap-fit ​​groove 8 on the primary base 1. Then, the car battery body 7 is placed on top of the insulating protective layer 9 and the secondary base 6 is placed in place, so that the snap-fit ​​rod 16 is snapped into the primary base 1, and the snap-fit ​​plate 19 is snapped into the fixing cavity 17 inside the support frame 5, so that the secondary base 6 is snapped and fixed. Then, the car battery body 7 is placed on top of the secondary base 6. After the placement is completed, the limiting device is rotated to limit and fix the car battery body 7.

[0020] Aluminum alloys possess high strength and hardness, capable of supporting the weight of automotive batteries. They maintain a stable structure even in low-temperature environments, resisting deformation and ensuring the safety and accuracy of the testing process. Their excellent thermal conductivity allows for rapid dissipation of heat generated by the battery during low-temperature testing, preventing localized overheating that could affect test results and contributing to maintaining uniform temperature around the battery. Polytetrafluoroethylene (PTFE) exhibits extremely high insulation resistance, effectively preventing battery leakage and avoiding short circuits and other safety accidents during testing. It also reduces the impact of external electromagnetic interference on test data. Furthermore, it maintains good physical properties even in low-temperature environments, preventing brittleness or cracking and providing stable support and protection for the battery. Its extremely low coefficient of friction reduces wear between the battery and the mounting bracket, preventing scratches on the battery surface.

[0021] Please see Figure 1-5 Furthermore, three first snap-fit ​​slots 8 are provided in the middle of the primary base 1 and the middle of the secondary base 6. Each of the three first snap-fit ​​slots 8 has a limiting bracket 10 in its inner cavity. An insulating protective layer 9 is fixedly provided in the middle of the first snap-fit ​​slot 8. The car battery body 7 is snapped into the inner cavity of the limiting bracket 10. A snap-fit ​​plate 19 is fixedly installed in the middle of the bottom of the secondary base 6. Snap-fit ​​rods 16 are fixedly installed at the four corners of the bottom of the secondary base 6. Second snap-fit ​​slots 18 are provided at the four corners of the top of the support frame 5. A fixing cavity 17 is provided in the inner cavity of the support frame 5. The snap-fit ​​rods 16 are correspondingly set with the second snap-fit ​​slots 18, and the snap-fit ​​plate 19 is correspondingly set with the fixing cavity 17.

[0022] In this embodiment of the application, after the secondary base 6 is installed, the rotating wheel 12 is rotated so that the rotating wheel 12 drives the bidirectional lead screw 13 to rotate in the rotating groove 11. At the same time, the rotation is limited by the limiting ring 14. The rotation of the bidirectional lead screw 13 drives the two limiting plates 15 to move inward synchronously until they contact the secondary base 6, limit the secondary base 6, and then stop rotating.

[0023] In practical use: When preparing for low-temperature testing of automotive batteries, the initial inspection and assembly process of the placement rack is crucial. Carefully examine the insulating protective layer 9; its surface should be smooth and flawless, without any scratches, holes, or peeling. The vertical support rod 4 and support frame 5 need to be checked from all angles for deformation or cracks. Gently shake them to confirm their stability, as their stability directly affects the overall load-bearing capacity of the placement rack. After completing the inspection, align the limiting bracket 10 with the first locking slot 8 on the primary base 1, and steadily lift the automotive battery body 7 with both hands, gently placing it on top of the insulating protective layer 9. Then, insert the locking rod 16 on the secondary base 6 into the second locking slot 18 on the support frame 5 on the primary base 1. Meanwhile, the snap-fit ​​plate 19 is accurately slid into the fixing cavity 17 inside the support frame 5. Then, the car battery body 7 is placed on the secondary base 6 again to complete the initial placement. To ensure the battery is stable, a limiting operation is required. Hold the rotating wheel 12 and rotate it at a constant speed. The rotating wheel 12 will drive the bidirectional lead screw 13 to rotate smoothly in the rotating groove 11. During the rotation, the axial transmission of the limiting ring 14 lead screw and the rotation of the bidirectional lead screw 13 will drive the two limiting plates 15 to move inward synchronously until the limiting plates 15 are connected to the groove of the battery to complete the limiting and fixing. Finally, the tester holds the handle 3 and pushes the placement rack. The battery placement rack loaded with the moving wheel 2 is pushed to the low temperature test site.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
