The mounting plate is used to be installed and fixed with the vehicle body, and screw holes are provided on the mounting plate, which are fixed with the vehicle body bolts through the screw holes. The reinforcing plate is provided to prevent the connection between the support frame and the mounting plate from breaking and deforming.
[0007] The wheel bracket is provided with limit plates on both sides. The limit plates are slidably connected with the support frame, and a gap is left between the top of the limit plates and the support frame.
[0008] A horizontal plate is provided on the top of one of the limit plates, a sleeve is fixed on the wheel bracket, a touch rod is sleeved in the sleeve, a restoring spring is provided at the bottom of the touch rod, one end of the restoring spring is fixed to the bottom of the sleeve, the top of the touch rod passes through the horizontal plate and is arranged above the horizontal plate, and a pressure-sensitive sensor is provided at the top of the touch rod. The pressure-sensitive sensor is connected to the controller on the vehicle body. When the pressure-sensitive sensor touches the support frame, the signal is transmitted to the controller. The contact time between the pressure-sensitive sensor and the support frame is set. If the timeout occurs, it means that the heavy object is overweight. The controller sends an alarm to the monitoring end or the alarm to remind the staff. Therefore, the purpose of setting the pressure-sensitive sensor is to avoid the vehicle body being overloaded with heavy objects and to ensure that a compression gap is left between the limit plate and the support frame. The setting of the restoring spring allows the touch rod to slide in the sleeve to avoid affecting the movement of the limit plate.
[0009] The beneficial effects of the utility model are as follows:
[0010] The driving stability of the AGV smart vehicle is ensured by setting a shock-absorbing spring to ensure the safety of the cargo. A reinforcement plate is set to prevent the connection between the support frame and the mounting plate from breaking and deforming. The purpose of setting a pressure-sensitive sensor is to prevent the vehicle from being overloaded with heavy objects and to ensure that a compression gap is left between the limit plate and the support frame.
