[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5A support plate for testing the chassis of a new energy vehicle includes a support plate 1, a moving mechanism, and a positioning mechanism. The moving mechanism includes a motor 2, a bidirectional lead screw 3, a sliding frame 4, and rollers 5. The motor 2 is fixedly installed inside the support plate 1. The bidirectional lead screw 3 is installed in the support plate and is rotatably connected to the support plate and fixedly connected to the output end of the motor 2. The sliding frame 4 is installed on the support plate and is slidably connected to the support plate and cooperates with the bidirectional lead screw 3. The rollers 5 are installed at the bottom of the sliding frame 4 and are rotatably connected to the sliding frame 4 and slidably connected to the support plate. The positioning mechanism includes a mounting plate 6, a spring 7, a locking block 8, and a cooperating component. The mounting plate 6 is installed on the sliding frame 4 and is slidably connected to the sliding frame 4. The spring 7 is fixedly installed in the mounting plate 6, and its other end is fixedly connected to the locking block 8. The locking block 8 is installed in the mounting plate 6 and is slidably connected to the mounting plate 6 and cooperates with the sliding frame 4.

[0031] In this embodiment, the moving mechanism includes a motor 2, a bidirectional lead screw 3, a sliding frame 4, and rollers 5. In use, the motor 2, which is fixedly mounted on the support plate 1, directly drives the bidirectional lead screw 3 to rotate, so that the bidirectional lead screw 3 can rotate in the support plate 1. The sliding frame 4, which is connected to the bidirectional lead screw 3, can slide in the sliding groove 12 of the support plate 1 under the action of the first threaded hole 14. The rollers 5 at the bottom of the sliding frame 4 slide in the running groove 13, so that the sliding frame 4 can slide stably on the support plate 1.

[0032] In this embodiment, the positioning mechanism includes a mounting plate 6, a spring 7, a locking block 8, and a mating assembly. During use, due to different vehicle models, the required support positions for the chassis vary. The mounting plate 6 can be installed onto the sliding frame 4. During installation, the mating groove 16 on the mounting plate 6 is slidably connected to the mating plate 17 in the sliding frame 4. Simultaneously, the locking block 8 is pressed directly, allowing it to slide on the positioning rod 18 of the mounting plate 6 and compress the spring 7, causing the locking block 8 to retract into the mounting plate 6. When the mounting plate 6 is fully installed onto the sliding frame 4, the locking block 8 engages with the locking hole 15, completing the fixation of the mounting plate 6. Furthermore, the position of the contact piece 9 that contacts the vehicle chassis can be adjusted by rotating the bolts. 10, so that bolt 10 can be rotatably connected to fixing plate 11, and the rotating bolt 10 is engaged with the second threaded hole 24 on contact member 9, so that fixing block 22 on fixing plate 11 can disengage from fixing hole 19 on mounting plate 6, thereby adjusting position. When adjusting position, limiting block 21 on contact member 9 slides in limiting groove 20 on mounting plate 6. When the position is appropriate, bolt 10 is rotated in the opposite direction, so that fixing block 22 on fixing plate 11 is engaged with fixing hole 19, thereby fixing the position of contact member 9. Support plate 1 is fixedly connected to lift. When contact member 9 contacts chassis, rubber pad 23 is engaged with chassis, thereby protecting chassis and supporting it.

[0033] Example 2:

[0034] In summary, during use, the motor 2, fixedly mounted on the support plate 1, directly drives the rotation of the double-acting screw 3, allowing the double-acting screw 3 to rotate within the support plate 1. The sliding frame 4, connected to the double-acting screw 3, slides in the sliding groove 12 of the support plate 1 under the action of the first threaded hole 14. The roller 5 at the bottom of the sliding frame 4 slides in the running groove 13, ensuring stable sliding of the sliding frame 4 on the support plate 1. Furthermore, due to different vehicle models and varying chassis support positions, the mounting plate 6 can be installed onto the sliding frame 4. During installation, the mating groove 16 on the mounting plate 6 is slidably connected to the mating plate 17 in the sliding frame 4. Simultaneously, the locking block 8 is pressed, allowing it to slide on the positioning rod 18 of the mounting plate 6 and compress the spring 7, causing the locking block 8 to retract into the mounting plate 6. When the mounting plate 6 is fully installed on the sliding frame 4, the locking block... Block 8 engages with the locking hole 15 to fix the mounting plate 6. Additionally, the position of the contact piece 9, which contacts the car chassis, can be adjusted. This is achieved by rotating bolt 10, allowing it to rotatably connect with the fixing plate 11. The rotating bolt 10 engages with the second threaded hole 24 on the contact piece 9, allowing the fixing block 22 on the fixing plate 11 to disengage from the fixing hole 19 on the mounting plate 6, thus adjusting its position. During this adjustment, the limiting block 21 on the contact piece 9 slides within the limiting groove 20 on the mounting plate 6. Once the position is correct, the bolt 10 is rotated in the opposite direction, causing the fixing block 22 on the fixing plate 11 to engage with the fixing hole 19, thereby fixing the position of the contact piece 9. The support plate 1 is then fixedly connected to the lift. When the contact piece 9 contacts the chassis, the rubber pad 23 engages with the chassis, protecting and supporting the chassis.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
