Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle lift testing, and in particular to a load-bearing testing device for an electric vehicle lift. Background Art

[0002] Electric vehicle lifts are an indispensable key equipment in the field of automobile maintenance. They are designed specifically for lifting cars safely and efficiently during automobile repair, maintenance and inspection operations. In actual applications, maintenance personnel will drive the electric car to be repaired smoothly to the designated work station of the lift, and then manually and precisely operate the lift's control system, using its built-in hydraulic or electric drive system to lift the car smoothly and steadily to a predetermined height, thereby creating a spacious and convenient operating space for maintenance personnel, facilitating a series of maintenance operations such as chassis inspection, parts replacement, and troubleshooting. In view of the important safety responsibilities of electric vehicle lifts in the automobile maintenance industry, the stability and reliability of their load-bearing performance are directly related to the personal safety of maintenance personnel and the smooth progress of maintenance operations. Therefore, in the production and manufacturing process of electric vehicle lifts, an electric vehicle lift load-bearing test device is needed.

[0003] As for the existing electric vehicle lift load-bearing test devices, traditional devices usually adopt a single, fixed fixing structure, which is difficult to adapt to electric vehicle lifts of different specifications and sizes; when faced with different models of lifts, it often takes a lot of time and energy to make complex adjustments, and it may not even be possible to achieve stable and reliable fixation, resulting in the lift offset, shaking and other phenomena during the load-bearing test, seriously affecting the accuracy and reliability of the test results; when operators are disassembling and assembling the lift, they usually need to stand in dangerous areas such as the bottom of the hydraulic telescopic rod. This operation method increases the difficulty of operation and greatly increases the risk of safety accidents; and during the load-bearing test, the lift may suffer structural damage due to excessive pressure, resulting in collapsed debris, which causes the operator to face the safety hazard of being injured by the debris. Summary of the Invention

[0004] An embodiment of the present invention relates to a load-bearing test device for an electric vehicle lift, which uses a dual-axis motor to drive a first double-headed screw to rotate, causing two sets of fixed plates to move inward at the same time, and cooperates with an adjustable limit plate to facilitate the positioning and fixation of lifts of different specifications; the mounting frame is linked with the test seat, and when the test seat moves, the mounting frame is automatically driven inward or outward through a gear rack transmission, thereby improving operational safety; after the mounting frame moves to the test position, the movable frame is pushed by the iterative block, and then the protective plate is automatically moved downward through the linkage plate, thereby enhancing the protective effect and preventing debris from affecting the safety of the operator.

Similarly, after the device test is completed, the test seat moves up and the mounting frame is automatically driven outward by the rotating shaft, so that the device has better linkage. The operator is placed at the outer end of the test frame to disassemble and assemble the lift, avoiding the need for the operator to stand at the bottom of the hydraulic telescopic rod for disassembly and assembly, which is easy to cause safety accidents, and effectively improves the safety of the device.

The second gear 1052 at the inner end of the rotating shaft 105 is in meshing transmission connection with the second rack 601 at the bottom of the test seat 6. When the test seat 6 moves downward from the uppermost position, the second rack 601 drives the rotating shaft 105 to rotate, so as to drive the mounting frame 4 to move inward automatically. When the test seat 6 moves to a position where the second rack 601 is not meshed with the second gear 1052, at this time, the mounting frame 4 moves to the middle position in the test frame 1 for a load-bearing test. Similarly, after the device test is completed, the test seat 6 moves upward, driving the mounting frame 4 to move outward automatically through the rotating shaft 105, making the device have better linkage. The operator disassembles and installs the lift 5 at the outer end of the test frame 1, avoiding the problem that the operator needs to stand at the bottom of the hydraulic telescopic rod 101 for disassembly and installation, which is likely to cause safety accidents, effectively improving the safety of the device; when the mounting frame 4 moves to the test position, the mounting frame 4 automatically pushes the moving frame 3 outward through the inclined block 302. The sliding hole of the connecting plate 201 at the outer end of the protective plate 2 is slidably installed on the support rod 102 at the left end of the test frame 1. The linkage plate 202 has a structure that is wider at the bottom and narrower at the top, that is, the moving frame 3 pushes the linkage plate 202 and the protective plate 2 to move downward automatically through the push block 301, so that the protective plate 2 can automatically move downward after the mounting frame 4 moves to the test position, effectively improving the protection effect of the device and avoiding the problem that the broken debris affects the safety of the operator when the device conducts a load-bearing test.
