[0002] The search announcement number is CN214894073U. Through the mutual cooperation of the cylinder, the base frame and the auxiliary rod, when the cylinder pushes the base frame to lift up, the auxiliary rod connected to the bearing can rotate in the base frame, so that the rolling element of the inner ring of the bearing can be in a simulated high slope tilt state.

The rotating part of the lifting motor 11 is used to drive the screw 12 to rotate, and the screw 12 drives the lifting frame 13 to move up and down, so as to adjust the positions of the two sets of laser levels 14 according to the height of the tricycle.

[0033] In this embodiment: the support mechanism 2 includes two flip arms 21, and the two flip arms 21 are rotatably connected to the detection platform 5. The two flip arms 21 are close to each other and fixed with a flip net bag 22 at one end, and the two flip arms 21 are rotatably connected to the flip hydraulic rod 23 at one end away from each other. The fixed part of the flip hydraulic rod 23 is rotatably connected to the frame 4. The detection platform 5 is located at the position of the flip arm 21 and has two flip openings, and the flip openings are fixed with pins for supporting the flip arms 21. The flip hydraulic rod 23 telescopic part is used to push the flip arm 21 to flip around the pin in the flip opening. Then the two flip arms 21 are flipped at the same time to lift the front wheel of the tricycle to be tested through the flip net bag 22, so that the front wheel of the tricycle can be quickly suspended to facilitate testing.

[0034] The adjustment mechanism 3 includes a two-way hydraulic rod 33, the fixing part of the two-way hydraulic rod 33 is arranged in the middle position of the bottom side of the frame 4, the two telescopic ends of the two-way hydraulic rod 33 are respectively fixed with sliding seats 34, the upper side of the sliding seat 34 is rotatably connected with a rotating wheel 35, the rotating wheel 35 is located at the bottom side of the lifting frame 31, the ends of the two lifting frames 31 away from each other are respectively slidably connected to the front and rear sides of the frame 4, the lifting frame 31 is rotatably connected with two symmetrical rotating rollers 32, the bottom of the lifting frame 31 is located between the two rotating rollers 32 and is provided with an inclined surface that fits the rotating wheel 35, and the detection platform 5 is located at the position of the lifting frame 31 and is provided with a groove for facilitating its upward lifting. The lifting frame 31 is provided with a T-shaped seat at one end close to the frame 4, and the frame 4 is provided with a T-shaped slot at the T-shaped seat for facilitating its up and down sliding. The telescopic part of the two-way hydraulic rod 33 is used to simultaneously drive the two sliding seats 34 to move forward or backward along the sliding rail, and then the inclined surface at the bottom of the lifting frame 31 is pushed by the rotating wheel 35 on the sliding seat 34, and then the lifting frame 31 on either side can move upward or downward, and then the detection of the two rear wheels in different height environments during the entire tricycle detection is completed.

[0035] Working principle: When in use, the tricycle to be tested is sent to the testing platform 5, at which time the rear wheel of the tricycle is located between the two rotating rollers 32, and then the front wheel of the tricycle is located on the flip net bag 22. At this time, the telescopic part of the flip hydraulic rod 23 is used to push the flip arm 21 to flip around the pin shaft in the flip opening, and then the two flip arms 21 are flipped at the same time to lift the front wheel of the tricycle to be tested through the flip net bag 22, and then the suspended support state of the front wheel of the tricycle can be completed;

[0036] At this time, the screw rod 12 is driven to rotate by the rotating part of the lifting motor 11, and then the screw rod 12 is used to drive the lifting frame 13 to move up and down, so that the positions of the two sets of laser level gauges 14 can be adjusted according to the height of the tricycle. At this time, the body balance of the tricycle can be detected by the laser level gauge 14. In addition, the two telescopic parts of the two-way hydraulic rod 33 can be moved backward at the same time, thereby driving the two sliding seats 34 and the rotating wheel 35 to move backward along the slide rail. At this time, the rear lifting frame 31 is pushed by the sliding seat 34 and the rotating wheel 35 at the rear end of the two-way hydraulic rod 33, and then the rear lifting frame 31 begins to slowly lift upward to facilitate the simulation of roads of different heights or slopes. The above steps are reversed to lift the front lifting frame 31 upward, and the rear lifting frame 31 falls back to its initial position, thereby simulating the balance detection of the tricycle under different road conditions.

[0037] In addition, by controlling the forward or backward extension distance of the bidirectional hydraulic rod 33, the positions of the two sliding seats 34 and the rotating wheels 35 on the lifting frame 31 can be adjusted, and then the lifting height of the lifting frame 31 can be accurately adjusted.
