[0004] However, during the operation of the above device, due to the heavy weight of the car engine, multiple people are required to lift the car engine or use lifting tools to lift the engine, and then move the car engine between the two circular clamps, and then rotate the rotating wheel to make the two circular clamps clamp the car engine to a limited position. However, since human power cannot apply a large torque to the rotating wheel, the clamping of the car engine by the circular clamp is not very stable, resulting in the car engine being very easy to fall during the process of rotating and displaying the car engine, which not only affects the teaching progress, but also poses a safety hazard.

[0024] See also Figure 4 The positioning structure 4 includes a movable rod 401 installed on the edge of the tray 2, and the movable rod 401 is rotatably connected to the tray 2 through a positioning shaft 402. The movable rod 401 is connected to the edge of the tray 2 in a movable abutment manner. Two symmetrically distributed coil springs 403 are fixedly sleeved on the outer side of the positioning shaft 402, and the outer end of the coil spring 403 is fixedly connected to the tray 2. The coil spring 403 can drive the movable rod 401 to rotate.

[0025] See also Figure 4 A ball 404 is movably embedded on the outer side of the movable rod 401 near its lower end, and the connection between the ball 404 and the inner wall of the display seat 1 is rolling contact. The ball 404 can reduce the friction between the movable rod 401 and the display seat 1. A pressing rod 405 penetrates the outer side of the movable rod 401 near its upper end, and a pressing block 406 is fixedly connected to the end of the pressing rod 405 away from the movable rod 401.

[0026] See also Figure 2 The support structure 5 includes a support rod 501 fixedly embedded in the lower end of the support plate 3, and the lower end of the support rod 501 is fixedly connected with a piston 502, the piston 502 is made of rubber, and the outer side of the piston 502 is movably sleeved with a sleeve 503, and the connection between the support rod 501 and the sleeve 503 is a plug-in connection, and the lower end of the sleeve 503 is fixedly sleeved with a base 504.

[0027] See also Figure 2 The base 504 is fixedly connected to the display stand 1, and the outer sides of the support rod 501 and the sleeve 503 are movably sleeved with a spring 2 505, which can drive the support plate 3 to move upward, and the two ends of the spring 2 505 are movably abutted against the support plate 3 and the base 504 respectively.

[0028] The working principle of the stable display of the new energy automobile engine: after the engine is placed on the tray 2, the tray 2 will move downward under the gravity of the engine. During the downward movement of the plurality of positioning structures 4 driven by the tray 2, the movable rod 401 will rotate against the inner wall of the display seat 1 until it rotates to a vertical state. At this time, the pressing block 406 at the end of the pressing rod 405 will press on the outer side of the automobile engine, so as to position the automobile engine and prevent the engine from moving or tilting during the rotation display of the automobile engine, thereby effectively improving the stability of the automobile engine during the display process;

[0029] When the car engine is moved upward, the tray 2 will move upward under the drive of the spring 2 505. After the movable rod 401 moves upward to a certain height, it will rotate under the drive of the coil spring 403, so that the pressing block 406 is separated from the car engine.

[0030] Embodiment 2

[0031] See also Figure 3 This embodiment further illustrates Example 1. The valve assembly 6 includes a cylindrical tube 601 fixedly embedded in the outer side of the sleeve 503 and interconnected with the sleeve 503. The cylindrical tube 601 is fixedly embedded in the inside of the base 504. One end of the cylindrical tube 601 away from the sleeve 503 is fixedly connected to the conical tube 602. A positioning frame 603 is fixedly installed inside the cylindrical tube 601.

[0032] See also Figure 3 A limiting rod 604 is fixedly embedded at the center of one side of the positioning frame 603 close to the conical tube 602, and a blocking ball 605 is movably sleeved on the outer side of the limiting rod 604. The limiting rod 604 can limit the moving trajectory of the blocking ball 605. The diameter of the blocking ball 605 is larger than the minimum diameter of the conical tube 602, and a plurality of exhaust holes 606 are opened on the blocking ball 605 and are evenly distributed around the circumference.

[0033] In this embodiment: in the process of moving the tray 2 and the piston 502 downward, the piston 502 squeezes the gas inside the sleeve 503, and the blocking ball 605 moves outside the limit rod 604 under the gas drive to block the smaller end of the tapered tube 602. At this time, the gas inside the sleeve 503 is slowly discharged through the exhaust hole 606 on the blocking ball 605, which is conducive to slowing down the speed of the tray 2 moving downward and the rotation speed of the movable rod 401, so as to facilitate the adjustment of the position of the automobile engine on the tray 2;

[0034] When the automobile engine moves upward, the piston 502 will move upward driven by the second spring 505. At this time, the gas will drive the blocking ball 605 to move toward the positioning frame 603, which is beneficial to the normal air intake of the sleeve 503, and the tray 2 will move upward at a faster speed.

[0035] Embodiment 3

[0036] See also Figure 4 This embodiment further illustrates the first embodiment. The outer side of the pressing rod 405 is movably sleeved with a spring 407, and the two ends of the spring 407 are movably abutted against the movable rod 401 and the pressing block 406 respectively.

[0037] In this embodiment, when the movable rod 401 drives the pressing rod 405 to rotate, the pressing rod 405 is squeezed and can move inside the movable rod 401. Under the action of the spring 407, the positioning structure 4 can adapt to the irregular shape of the automobile engine.
