[0002] As the most critical component when parking a vehicle, the two-wheeled vehicle owner's stand bears a large part of the vehicle's weight when parked, and is subjected to a strong instantaneous impact every time the vehicle is parked. Therefore, its ease of use and durability are important reference indicators.

[0003] In order to effectively verify the durability and reliability of the main stand for parking two-wheeled vehicles during the product development phase, the current method is to manually simulate the use of the main stand for parking. However, it is very challenging to complete the durability test task in a short period of time. Ordinary users use the main stand for parking about 6 times a day, and the entire vehicle life cycle requires about 20,000 parking times. The frequency of food delivery users is even higher. Completing the test in a short period of time causes great damage to the upper and lower limbs of the testers, which reduces the reliability of the process, makes the test process uncontrollable, and reduces the validity of the test results.

DETAILED DESCRIPTION

[0033] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the two-wheeled vehicle main support durability testing device of this embodiment includes a base frame 15 for limiting the vehicle movement path, and the base frame 15 is provided with a parking component, a trolley component, and a control cabinet 1 for controlling the parking component and the trolley component.

[0037] The pressure cylinder 4 is located at the base frame 15 near the rear of the vehicle and is used to provide the force to press the vehicle main support 8 and the foot 6.

[0038] The cart assembly includes,

[0039] The front pulling cylinder 12 is located on the base frame 15 near the front of the vehicle and is used to provide traction.

[0040] The limiting block group is located on the base frame 15 and contacts the forward side of the vehicle main support 8.

[0041] The rear handrail tension cylinder 3 and pressure cylinder 4 are both tilted.

[0042] The tilt angle of the rear armrest tension cylinder 3 is consistent with the movement path of the rear end of the vehicle when parking;

[0043] The inclination angle of the pressure cylinder 4 is consistent with the downward pressing path of the vehicle main support 8 and the stepping foot 6.

[0044] The rear armrest tension cylinder 3 is located above the vehicle to be tested, and the pressure cylinder 4 is located above the footrest 6 of the main support 8 of the vehicle to be tested.

[0045] The vertical height of the base frame 15 near the rear of the vehicle is greater than the height of the vehicle to be tested, forming a three-dimensional support frame. The control cabinet 1 is installed on the top of the support frame, and the rear armrest tension cylinder 3 and pressure cylinder 4 are installed on the wall of the support frame away from the control cabinet 1.

[0046] The limit block group includes a first stopper 7 and a second stopper 9 located on the support frame. The first stopper 7 and the second stopper 9 are respectively located at the front and rear sides of the main support 8 of the vehicle to be tested in the moving direction.

[0047] The base frame 15 is provided with:

[0048] The rear wheel limiting groove 5 is located at the base frame 15 near the rear of the vehicle.

[0049] The fixed frame rail 14 is located on the base frame 15 near the front of the vehicle.

[0050] The front wheel fixing frame 11 is slidably connected to the fixing frame slide rail 14 and is fixedly connected to the front wheel axle 10 of the vehicle to be tested. The front tension cylinder 12 drags the front wheel fixing frame 11 to slide back and forth.

[0051] The front wheel fixing frame 11 is clamped and connected to both ends of the front wheel axle 10 of the vehicle to be tested, and the force point of the front tension cylinder 12 is located at the midpoint of the front wheel fixing frame 11 .

[0052] The front pulling cylinder 12 is equipped with a cylinder positioning seat 13 with a fixed relative position, and the cylinder positioning seat 13 and the rear wheel limiting groove 5 are arranged in a collinear manner.

[0053] The specific structure and working process of the utility model are as follows:

[0054] The utility model mainly utilizes the base frame 15 to support the limited vehicle, and on the basis of the base frame 15, additional pressure and tension power sources for parking and a tension power source for pushing the vehicle are provided to simulate manual parking and pushing.

[0055] When parking, the pressure cylinder 4 is used to provide the pressure for stepping on the vehicle's main bracket 8 and the foot 6, and the rear armrest tension cylinder 3 is used to provide the pulling force for lifting the vehicle's rear armrest, simulating the pressure of stepping on the main bracket 8 and the foot 6 and the pulling force of lifting the rear armrest when manually parking.

[0056] When pushing the car, the second block 9 blocks the side of the vehicle main bracket 8 in the forward direction, and the front tension cylinder 12 pulls the front wheel fixing frame 11 at the front of the car to pull the entire car forward, completing the pushing action and the vehicle main bracket 8 is folded up.

[0057] The entire set of parking and pushing actions is a cycle. The actions of the rear armrest pulling cylinder 3, the pressure cylinder 4 and the front pulling cylinder 12 are all automatically controlled by the control cabinet 1, and a counting display is installed on the control cabinet 1 to display the number of tests.

[0058] The specific operation of parking is as follows:

[0059] The vehicle has been placed on the base frame 15 in advance. When parking is required, the upper end of the pressure cylinder 4 takes in air and the lower end exhausts air. The piston rod of the pressure cylinder 4 is connected to the footrest of the vehicle main support 8. When the piston rod extends, it presses the footrest of the vehicle main support 8 downward, simulating the rider's right foot stepping down. The rear armrest tension cylinder 3 takes in air at the lower end and exhausts air at the upper end. The output shaft of the rear armrest tension cylinder 3 is connected to a fabric plate belt, which pulls the vehicle's rear armrest, simulating the action of a person's right hand pulling the rear end of the vehicle upward.

[0060] Under the control of the electrical system of the control cabinet 1, the pressure cylinder 4 and the rear armrest tension cylinder 3 work simultaneously to complete a parking operation. At this time, the front tension cylinder 12 is in a naturally exhausted state and does not provide any pulling or pushing force. It is restricted to both sides of the main bracket 8 by the first block 7 and the second block 9, ensuring that the front and rear positions of the vehicle are within the specified range after parking. At the same time, the first block 7 and the second block 9 can also appropriately play the role of resisting the main bracket 8 of the vehicle and providing a reaction force when parking and pushing the vehicle. In addition, the rear wheel limit slot 5 ensures that the left and right positions of the rear end of the vehicle are within the specified range. The front wheel fixing frame 11 cooperates with the fixing frame slide rail 14 to ensure that the front of the vehicle moves within the specified range.

[0061] When pushing a cart, the front tension cylinder 12 takes in air at the front end and exhausts air at the rear end, pulling the front wheel bracket 11. The front wheel bracket 11 moves on the bracket slide rail 14, pulling the front wheel axle 10, providing a forward pulling force on the vehicle, simulating the thrust applied to a two-wheeled vehicle when a person pushes a cart. At this time, the second block 9 blocks the front end of the vehicle main frame 8, simulating the force of a person's feet blocking the vehicle main frame 8 when pushing a cart. At this time, the pressure cylinder 4 and the rear armrest tension cylinder 3 are in a natural exhaust state and do not provide any pulling or pushing force. The pressure cylinder 4 is passively retracted, and the piston rod retracts; the vehicle main frame 8 is then retracted, and the rear armrest tension cylinder 3 lowers the fabric plate belt, and the entire vehicle falls accordingly, entering the push cart ready for riding.

[0062] One parking maneuver and one push constitute a cycle. The movements of the rear armrest tension cylinder 3, pressure cylinder 4, and front tension cylinder 12 are all controlled by control cabinet 1, and the number of times is recorded by a counter. Different vehicle weights correspond to different downward pressures from pressure cylinder 4, upward pulls from rear armrest tension cylinder 3, and traction forces from front tension cylinder 12. These values are collected through manual simulation and then adjusted using control cabinet 1 based on actual operating conditions to ensure the test device's performance matches the user's actual parking state.

[0063] The advantage of the utility model is that it adopts an automatic parking and pushing structure to replace manual testing, and can control the size of the pushing and pulling forces, is applicable to vehicles of various specifications, and improves the accuracy of the test results.

[0064] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
