As shown in FIG. 1, a resilient spacer 170 is disposed in the gap between the tub 120 and the body 110. When a weight is placed in the tub 120, the tub 120 is relatively opposed to the body due to the gravity of the object loaded thereon. The displacement is generated to compress the resilient spacer 170 to deform the resilient spacer 170. In a specific case In the middle, the elastic spacer 170 is disposed between the beam of the body 110 and the bracket of the tub 120, and the elastic spacer 170 may be a combination of one or both of the wood chip and the rubber sheet. Among them, the wood piece has the function of damping, and the rubber piece has the function of stopping slip, and the wood piece and the rubber piece itself have elasticity, so the use of the wood piece with the rubber piece can achieve the effect of shock absorption and anti-slip. In the embodiment, the sensing device 151 generates a corresponding sensing signal according to the deformation amount of the elastic spacer 170, and transmits the sensing signal to the processing unit 152.

In an embodiment, the database 155 stores information such as weight information of the relevant bucket body and vehicle speed control reference materials. In a specific example, the system builder may first record the initial position of the barrel 120 in the empty bucket state, and then load the objects of different weights in the bucket 120 and record the deformation amount of the elastic spacer 170. A linear graph of the relationship between the shape variable and the weight is established, thereby providing the processing unit 152 to generate a corresponding weight message according to the shape variable sensing signals of the different elastic spacers 170.

One end of the movable member 151d is connected to the first fitting 151a. When the first assembly 151a moves relative to the second assembly 151b, the movable movable member 151d is displaced relative to the signal generating unit 151e, thereby causing the signal generating unit 151e to generate a sensing signal. In this embodiment, the movable member 151d is a thimble, and the signal generating unit 151e is a resistive sensing unit. When the movable member 151d moves relative to the signal generating unit 151e, the signal generating unit 151e generates a resistance change, and the resistance change can be used as a sense. Test signal. In some examples, the signal generating unit 151e may be an element such as a metal piece, a spring or a pressure sensing piece that can sense a displacement change of the movable member 151d.

After the processing unit 152 receives the sensing signal, the sensing signal can be converted into a weight message, and then the determination result is further generated according to the weight information. In an example, the processing unit 152 can convert the sensing signal into a weight message according to a linear graph of the relationship between the shape variable and the weight of the elastic spacer 170 stored in the database 155. In an embodiment, the processing unit 152 determines whether the load of the tub 120 exceeds a preset safety value according to the weight information, thereby generating a determination result. For example, when the load of the tub 120 has exceeded the load weight of the entire truck 100, the judgment result is "alert"; when the load of the tub 120 has not exceeded the load of the entire truck 100, but has arrived at a pre-load When the threshold is set, the judgment result is "attention"; when the barrel 120 is When the load does not reach the preset threshold, the judgment result is "safe".

When the vehicle controller 140 receives the weight message and the judgment result, the driving device 130 can be controlled according to the judgment result, so as to appropriately control the moving speed. In some examples, when the determination result is "alert", the vehicle controller 140 may control the driving device 130 to reduce the motor speed of the truck 100 to limit driving to only a certain safe speed to travel or turn. When the judgment result is "Attention", the vehicle controller 140 can issue a notification to the driving through the display device 160, thereby reminding the driver to pay attention to driving safety. When the judgment result is "safe", the vehicle controller 140 operates normally according to the operation of the driving, and the vehicle controller 140 can display the current load state to the driving reference through the display device 160.
