Description

Technical Field

[0001] This utility model relates to a vehicle-mounted weighing structure. Background Technology

[0002] Currently, weighing goods on trucks is an essential part of the transportation industry, involving not only regulatory compliance and economic interests but also traffic safety. However, most existing trucks cannot directly weigh the goods on board; instead, they require a truck scale to weigh the entire truck and then subtract the truck's own weight to obtain the cargo weight. For example, Chinese patent CN221898598U discloses an electronic truck scale weighing device. However, this method of weighing the entire truck and then subtracting its own weight to obtain the cargo weight is inefficient and inconvenient in practice. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a vehicle-mounted weighing structure that can directly weigh the weight of goods on a truck, thereby improving the efficiency and convenience of weighing the weight of goods on a truck.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a vehicle-mounted weighing structure, including a frame, an axle device, a controller, at least two front weighing components and at least two rear weighing components;

[0005] The front weighing assembly includes a front leaf spring, a front tilt sensor, and a front connecting arm;

[0006] The middle part of the front leaf spring is connected to the axle assembly, one end of the front leaf spring is hinged to the frame, the other end of the front leaf spring is hinged to one end of the front connecting arm, and the other end of the front connecting arm is hinged to the frame.

[0011] The controller is connected to the front tilt sensor and the rear tilt sensor respectively and is used to obtain the weight of the cargo loaded on the frame based on the tilt angle changes detected by the front tilt sensor and the rear tilt sensor.

[0012] Furthermore, there are two front weighing components arranged side by side on the left and right, and two rear weighing components arranged side by side on the left and right.

[0013] Further, a specific structure of the axle device is provided, the axle device including a front axle and a rear axle, the middle part of the front leaf spring is connected to the front axle, and the middle part of the rear leaf spring is connected to the rear axle.

[0014] Furthermore, each of the front leaf springs is connected to a yaw angle sensor, which is connected to the end of the corresponding front leaf spring that is hinged to the front connecting arm.

[0020] Furthermore, the controller is a weighing controller.

[0021] After adopting the above technical solution, the frame is located above the front leaf spring and the rear leaf spring. When the frame is not loaded with goods, both the front and rear leaf springs are in their initial state. When goods are loaded onto the frame, the weight of the goods is transferred to the front and rear leaf springs, causing them to straighten under stress. At this time, the tilt sensor can detect the tilt angle change at the part of the front leaf spring connected to the sensor, and the tilt sensor can detect the tilt angle change at the part of the rear leaf spring connected to the sensor. The controller can then obtain the weight of the goods loaded on the frame based on the tilt angle changes detected by the tilt sensors and the rear tilt sensor, and then control the display screen to display the weight. The vehicle-mounted weighing structure of this embodiment can directly weigh the weight of goods loaded on the truck frame, greatly improving the efficiency and convenience of weighing goods on trucks.

When goods are loaded onto the frame 1, the weight of the goods is transferred to the front leaf spring 4 and the rear leaf spring 7, causing them to straighten under stress. At this time, the tilt angle sensor 5 can detect the tilt angle change at the part of the front leaf spring 4 connected to the tilt angle sensor 5, and the tilt angle sensor 8 can detect the tilt angle change at the part of the rear leaf spring 7 connected to the tilt angle sensor 8. Then, the controller can obtain the weight of the goods loaded on the frame 1 based on the tilt angle changes detected by the tilt angle sensor 5 and the tilt angle sensor 8, and then control the display screen to display the weight. The vehicle-mounted weighing structure of this embodiment can directly weigh the weight of goods loaded on the frame 1 of the truck, greatly improving the efficiency and convenience of weighing the goods on the truck. The specific structures of the forward tilt sensor 5 and the backward tilt sensor 8 are both existing technologies.

[0045] In summary, the frame 1 is located above the front leaf spring 4 and the rear leaf spring 7. When the frame 1 is not loaded with goods, both the front leaf spring 4 and the rear leaf spring 7 are in their initial state. When goods are loaded onto the frame 1, the weight of the goods is transferred to the front leaf spring 4 and the rear leaf spring 7. At this time, both the front leaf spring 4 and the rear leaf spring 7 will straighten under force. The tilt angle sensor 5 can detect the tilt angle change of the part of the front leaf spring 4 connected to the tilt angle sensor 5, and the tilt angle sensor 8 can detect the tilt angle change of the part of the rear leaf spring 7 connected to the tilt angle sensor 8.
