Position detection device and vehicle

Abstract

A position detection device relates to the technical field of on-vehicle weighing machinery, and comprises an angle sensing device, a rotating arm and a pre-tightening device; the rotating arm is rotatably connected to the angle sensing device, one end of the pre-tightening device is connected to the rotating arm or connected to a common foundation together with the rotating arm, and the other endof the pre-tightening device is connected to the angle sensing device or connected to the common foundation together with the angle sensing device. The vehicle adopts the position detection device. The pre-tightening device is additionally arranged, so that the position detection device has a stable detection reference, and the detection results of each time are more accurate; in addition, the rotating arm and the position detection device can be prevented from being pulled apart when the distance between the two parts is increased, and the position detection device can be suitable for detecting the position relation of the two parts with the large relative movement range or the unstable position relation; according to the invention, the position detection device cannot be damaged due tothe change of the distance between an axle and a frame.

Description

technical field [0001] The invention relates to the technical field of on-vehicle weighing machinery, in particular to a position detection device and a vehicle. Background technique [0002] In the prior art, an angle sensing device can be used to detect the relative positional relationship (such as angle relationship and distance relationship) of two relatively moving parts (such as the first part and the second part), for example, the angle sensor device is installed on the first part , the rotating arm that rotates relative to the angle sensing device is hinged on the second part, and when the second part moves relative to the first part, the rotating arm is driven to rotate, and the angle sensing device is used to detect the rotation angle of the rotating arm relative to the angle sensing device. The specific positional relationship (angular relationship or distance relationship in a specific direction) between a component and a second component has a one-to-one corresp...

Problems solved by technology

[0006] Based on this, some vehicle load detection equipment came into being, such as the weighbridge, which determines the load weight by weighing the weight of the vehicle before and after loading. However, the weighbridge is expensive and the installation location is fixed, and the vehicle needs to be driven to the weighbridge. Weighing is inconvenient to use, and it is also not conducive to real-time monitoring of vehicle load capacity

[0007] In order to solve the above problems, in the prior art, a rotating arm is connected between the axle and the frame, and the distance change between the axle and the frame is converted into the angle change of the rotating arm relative to the axle (or frame) , and then use the angle sensing device to detect the angle of the pivot arm relative to the axle (or frame) to detect the way the vehicle is loaded; however, the driving and use conditions of the vehicle (especially the truck) are often complicated, and the vehicle is in poor road conditions. When driving on a rough road, the distance between the axle and the frame will vary depending on the potholes on the road surface; Pulling on the arm, causing damage to the arm and angle sensing device
