Problems solved by technology

Since the push rod needs to move in a straight line in the front and back direction, a linear drive mechanism is required. Generally, a hydraulic cylinder is used as this linear drive mechanism, but the linear drive mechanism such as a hydraulic cylinder responds slowly, and there is a serious hysteresis phenomenon, which leads to deviation correction. poor control

[0011] Such as figure 1 It is a three-dimensional schematic diagram of the first embodiment of the vehicle deviation correcting device of the present invention. figure 2 is a sectional view of the installation structure of the first embodiment of the vehicle deviation correcting device of the present invention; image 3 It is a wiring diagram of the first embodiment of the vehicle deviation correcting device of the present invention. Such as Figure 1-3 As shown, the vehicle deviation correction device includes a humanoid actuator 1 , a detection device 2 and a controller 3 .

[0012] Such as figure 1 and figure 2 As shown, the humanoid actuator 1 includes a motor 101, a mounting plate 102 and a fixed rod 103, the mounting plate 102 is disc-shaped, and three connecting arms 104 protruding outward are arranged around it, and the three connecting arms 104 are evenly distributed around the mounting plate 102 . The three connecting arms 104 of the mounting plate 102 are co...

[0022] The second embodiment is basically the same as the first embodiment, except that the telescopic sliding structure of the fixing rod 103 of the second embodiment is different from that of the first embodiment.

[0023] Such as Figure 4 As shown, the fixed tube 103 a and the telescopic tube 103 b of the fixed rod 103 are connected together through a sliding sleeve 205 . Specifically, the protruding end of the telescopic tube 103b is engaged in the inner wall of one end of the sliding sleeve, and the fixed tube 103a is slidably inserted into the sliding sleeve 205 from the other end of the sliding sleeve. Therefore, the telescopic tube 103b can telescopically slide relative to the fixed tube 103a, so as to prevent the jamming phenomenon caused by the shaft of the motor 101 not concentric with the steering wheel 4 .

Abstract

The invention discloses a vehicle deviation correction device, comprising: a humanoid actuator for turning the steering wheel, the humanoid actuator includes a motor, a mounting plate and a fixing rod, the mounting plate is detachably connected to the steering wheel, the motor shaft and the mounting The plate is detachably connected so as to drive the mounting plate and the steering wheel to rotate together, and the fixed rod fixes the motor to the vehicle body, and the fixed rod can slide telescopically to prevent jamming caused by the misalignment of the motor shaft and the steering wheel; the detection device, the The detection device is used to detect vehicle deviation status information; and a controller, the controller controls the rotation of the motor according to the deviation status information of the detection device. The humanoid actuator of the present invention can be easily installed on the steering wheel, so the direction of the vehicle can be arbitrarily adjusted as required by human hands. Simultaneously, since the fixed rod of the present invention can slide telescopically, there will be no stuck phenomenon when the motor shaft is not concentric with the steering wheel.

Description

technical field [0001] The invention relates to a vehicle deviation correcting device. Background technique [0002] In some cases, the vehicle cannot be driven by a human, but needs to be driven autonomously, for example, when customs are conducting security checks on container vehicles. However, it is easy for the vehicle to deviate when driving autonomously, so the vehicle needs to have a deviation correction device. In order to solve this technical problem, in the prior art, a special vehicle with a deviation correction device is generally used. This special vehicle adopts a push rod type deviation correction device. When the vehicle deviates, the push rod is pushed back and forth within a range of 90 degrees to adjust Wheel bearing angle. Since the push rod needs to move in a straight line in the front and back direction, a linear drive mechanism is required. Generally, a hydraulic cylinder is used as this linear drive mechanism, but the linear drive mechanism such as...
