As shown, the appliance control device 110 of the vehicle testing device 100 is supported on a mounting device 120, and the mounting device 120 is adapted to be mounted on a track of a vehicle seat to stabilize the appliance control device 110. One side of the electric control device 110 is connected to an accelerator pedal and a brake pedal 140 through a link 130. The illustrated accelerator and brake pedals 140 lock the vehicle's accelerator and brake, respectively. The pushing and retrieving of the link 130 is controlled by the electric control device 110 to apply a certain pressure to the accelerator pedal or the brake pedal 140 during the vehicle test process, to complete the designated actions such as the vehicle advancing, accelerating, decelerating, braking, etc., during which various performances of the vehicle are detected. The appliance control device 110 further includes a link control device disposed therein.
Fig. 2 shows a schematic structural diagram of an embodiment of the present application. Fig. 3 shows a schematic structural diagram of an embodiment of the present application. Fig. 4 is a left side structural schematic diagram of fig. 3. As shown in the drawing, the link control device 200 is disposed in the electric control device 110 of the vehicle testing device 100, and the link control device 200 mainly includes a fixing base 210, a motor assembly 220, a first gear 230, a second gear 240, a linkage shaft 250, a first rotating arm 260, a second rotating arm 270, a first rotating disc 280, and a second rotating disc 290.
Wherein, the motor assembly 220 is disposed on the fixing base 210. The output shaft 221 of the motor assembly 220 serves as a driving shaft of the first gear 230 and the first rotary arm 260 to drive the first gear 230 and the first rotary arm 260 to rotate. The first gear 230 is meshed with the second gear 240, and the output shaft 221 of the motor assembly 220 rotates to drive the first gear 230 to act, so as to drive the second gear 240 to rotate, and the rotation directions of the second gear 240 and the first gear 230 are opposite.
The coupling shaft 250 is disposed on the fixing base 210. One end of the linkage shaft 250 is connected to the second gear 240, for example, one end of the linkage shaft 250 may be directly fixed at the central axis of the second gear 240, and the rotation of the second gear 240 can drive the rotation of the linkage shaft 250. A second rotating arm 270 is provided at the other end of the linkage shaft 250, and rotation of the linkage shaft 250 drives the second rotating arm 270 to rotate.
The first rotating arm 260 is rotated in the opposite direction to the second rotating arm 270. The first rotating arm 260 can drive the first rotating disk 280 to rotate, and the second rotating arm 270 can drive the second rotating disk 290 to rotate. In one embodiment, the first turntable 280 is movably fixed to the output shaft 221 of the motor assembly 220, and can rotate around the output shaft 221 under the driving of the first rotating arm 260. In another embodiment, the second turntable 290 is movably fixed on the linkage shaft 250, and can rotate around the linkage shaft 250 under the driving of the second rotating arm 270.
Referring to fig. 2, a linkage control device 200 is described having only one motor assembly 220. When the motor assembly 220 is operated, the output shaft 221 of the motor assembly rotates clockwise in the direction indicated by the arrow at the illustrated position, and the transmission shafts of the first gear 230 and the first rotating arm 260 can drive the first gear 230 and the first rotating arm 260 to rotate clockwise. The first rotating arm 260 gradually approaches the first rotating disc 280 and finally is tangential to the first rotating disc 280 and transmits torque to the first rotating disc 280, and the first rotating disc 280 is supported by the first rotating arm 260 to rotate around the output shaft 221 of the motor assembly 220. The push rod 130 shown in fig. 1 is connected to the first turntable 280, and when the first turntable 280 rotates clockwise, the push rod 130 extends to the accelerator pedal or the brake pedal, and it is assumed here that the push rod 130 on the first turntable 280 is connected to the accelerator pedal, i.e., the first turntable 280 rotates clockwise, an operation for supplying the accelerator is performed.
At the same time, the output shaft 221 of the motor assembly 220 drives the first gear 230 to rotate clockwise, the second gear 240 correspondingly rotates counterclockwise, the second gear 240 drives the linkage shaft 250 to rotate counterclockwise, and the linkage shaft 250 drives the second rotating arm 270 to rotate counterclockwise. The second rotary table 290 maintains its initial state unchanged, the second rotary arm 270 rotates counterclockwise, gradually away from the second rotary table 290, the push rod 130 is also connected to the second rotary table 290, the push rod 130 extends to the accelerator pedal or the brake pedal, here, it is assumed that the push rod 130 on the second rotary table 290 is connected to the brake pedal, the second rotary arm 270 rotates counterclockwise, and the second rotary table 290 does not act. In effect, when the motor assembly 220 is operated and the output shaft 221 thereof is rotated clockwise, the first rotating arm 260 is rotated clockwise to press the accelerator pedal, and the second rotating arm 270 is rotated counterclockwise, and the brake pedal is not operated.
When the brake pedal is required to be operated, the output shaft of the motor assembly 220 rotates counterclockwise at the illustrated position and drives the first gear 230 and the first rotating arm 260 to rotate counterclockwise. The free end of the first rotating arm 260 descends, and the accelerator pedal connected with the push rod 130 of the first rotating disc 280 generates torque by the spring restoring force of the accelerator pedal and the self weight of the first rotating disc 280, so that the first rotating disc 280 rotates anticlockwise against the first rotating arm 260 to return to the initial position shown in the figure, namely, the accelerator pedal is released.
At the same time, the output shaft of the motor assembly 220 drives the first gear 230 to rotate counterclockwise, the second gear 240 correspondingly rotates clockwise, the second gear 240 drives the linkage shaft 250 to rotate clockwise, and the linkage shaft 250 drives the second rotating arm 270 to rotate clockwise. The second swivel arm 270 gradually approaches the second swivel plate 290 and finally is tangent to the second swivel plate 290 and transmits torque to the second swivel plate 290, and the second swivel plate 290 is rotated around the coupling shaft 250 by the second swivel arm 270. The link 130 connected to the second turntable 290 extends to the brake pedal, i.e., the second turntable 290 performs a braking operation when rotated clockwise. It will be readily appreciated that when the motor assembly 220 is operated and the output shaft 221 thereof is rotated counterclockwise, the first arm 260 is rotated counterclockwise to release the accelerator pedal and the second arm 270 is rotated clockwise to depress the brake pedal.
Therefore, since the connecting rod control device 200 provided by the application has only one motor assembly 220, the first and second rotating arms 260 and 270 are driven to rotate in opposite directions by the cooperation of the first and second gears 230 and 240 and the linkage shaft 250, and further drive the brake pedal or the accelerator pedal respectively, so that the condition that the accelerator pedal and the brake pedal work simultaneously is effectively avoided. The method is equivalent to manual control of the vehicle, the right foot is used for controlling the accelerator pedal and the brake pedal, and only the brake pedal or the accelerator pedal can be stepped on at the same time. In addition, the single motor assembly 220 is adopted, so that the overall structure of the connecting rod control device 200 is simple, the overall size is reduced, the cost is reduced, and the control is more convenient.
Preferably, the link control device 200 further includes a first limit and a second limit. The first limit is for supporting the first turntable 280 to remain in its initial position and the second limit is for supporting the second turntable 290 to remain in its initial position. The first and second stoppers may be provided on the fixing base 210 such that the first and second turntables 280 and 290 are always in a state where the gravity-generated torque pulls back the link 130 connected thereto. Thus, when the accelerator pedal or the brake pedal is returned, the pull rod 130 is quickly and smoothly pulled back to the starting (zero) point position by the torque generated by the spring force of the accelerator pedal or the brake pedal and the weight of the first rotary disk 280 and the second rotary disk 290.
Preferably, the first rotating disc 280 has a first rotating bar 281, a return device 300 is disposed at an end of the first rotating bar 281, and the first rotating arm 260 drives the first rotating disc 280 to rotate through the return device 300.
Preferably, the second rotary table 290 has a second rotating bar 291, a third limit 292 is disposed on the second rotating bar 291, and the second rotary arm 270 drives the second rotary table 290 to rotate through the third limit 292.
Preferably, the axis of the linkage shaft 250 and the axis of the output shaft 221 of the motor assembly 220 are parallel to each other and lie in the same vertical plane.
Preferably, the second gear 240 is located above the first gear 230.
Preferably, the rotation angle of the first and second rotary discs 280 and 290 is less than 90 degrees. So that the center of gravity of the first rotary plate 280 is always maintained at one side of the output shaft 221 of the motor assembly 220, and once the first rotary arm 260 rotates counterclockwise, the first rotary plate 280 rotates counterclockwise against the first rotary arm 260 by gravity, pulling back the link 130 connected thereto. Likewise, the center of gravity of the second rotary plate 290 is always maintained at one side of the linkage shaft 250, and once the second rotary arm 270 rotates counterclockwise, the second rotary plate 290 rotates counterclockwise against the second rotary arm 270 under the action of gravity, pulling back the link 130 connected thereto.
Preferably, the first rotating disc 280 further has a third rotating bar 282 integrally formed with the first rotating bar 281, and an end of the third rotating bar 282 is connected to the link 130. When the first rotary arm 260 rotates clockwise, the first rotary disc 280 is driven to rotate, and the third rotary bar 282 pushes the connecting rod 130 to extend forwards to press the accelerator pedal. Similarly, the second turntable 290 further has a fourth rotation bar 293 integrally formed with the second rotation bar 291, and an end of the fourth rotation bar 293 is connected to the link 130. When the second rotary arm 270 rotates clockwise, the second rotary plate 290 is driven to rotate, and the fourth rotary bar 293 pushes the connecting rod 130 to extend forwards to press the brake pedal. More preferably, the first rotation bar 281 forms a 90 degree angle with the third rotation bar 282, and the second rotation bar 291 forms a 90 degree angle with the fourth rotation bar 293.
Fig. 5 shows a schematic structural view of a return device according to an embodiment of the present application. Fig. 6 shows a front view of a return device according to an embodiment of the application. Fig. 7 is a cross-sectional view taken along A-A of fig. 6. As shown, the return device 300 includes a base 310, an electromagnetic chuck 320, and a transfer shaft 330. The electromagnetic chuck 320 is disposed at one side of the base 310, the end of the first rotation bar 281 is fixed to the base 310, and the transfer shaft 330 is disposed at the other side of the base 310. When the electromagnetic chuck 320 is powered on, the return device 300 can enter a locked state, and one side of the transmission shaft 330 can be attached to the electromagnetic chuck 320 under the action of magnetic force. When the electromagnetic chuck 320 is powered off, the return device 300 is released, the electromagnetic chuck 320 loses magnetic force, and one side of the transmission shaft 330 is far away from the electromagnetic chuck 320. In other words, the transmission shaft 330 can be switched between two states of magnetic attraction to the electromagnetic chuck 320 and separation from the electromagnetic chuck 320 corresponding to the locked and released states of the return device 300. Referring to fig. 2, when the link control device 200 is operated, the electromagnetic chuck 320 is powered on, one side of the transmission shaft 330 is magnetically attracted to the electromagnetic chuck 320, the return device 300 is in a locked state, the output shaft 221 of the motor assembly 220 rotates clockwise in the direction indicated by the arrow at the position shown in fig. 2, the first rotating arm 260 gradually approaches one side of the transmission shaft 330 of the return device 300, and finally, the first rotating arm 260 is tangent to the transmission shaft 330 and transmits torque to the return device 300 through the transmission shaft 330, so as to drive the first rotating bar 281 of the first rotating disc 280 to rotate. The push rod 130 shown in fig. 1 is connected to the first dial 280, and when the first dial 280 rotates clockwise, the push rod 130 extends to the accelerator pedal to perform an operation for applying the accelerator. When the link control apparatus 200 encounters a power failure, the electromagnetic chuck 320 instantaneously loses magnetic force, and one side of the transfer shaft 330 rapidly moves away from the electromagnetic chuck 320, so that a gap is formed between the electromagnetic chuck 320 and one side of the transfer shaft 330, and the return apparatus 300 enters a released state, through which the first rotating arm 260 can pass. In the process that the first rotating arm 260 drives the first rotating disc 280 to rotate, once the electromagnetic chuck 320 is powered off, the first rotating arm 260 cannot support the transmission shaft 330, the accelerator pedal connected with the push rod 130 of the first rotating disc 280 is subjected to the spring restoring force of the accelerator pedal and the self weight of the first rotating disc 280 to generate torque, the first rotating arm 260 passes through the restoring device 300 in the releasing state, and the first rotating disc 280 is instantly lowered to the initial position, which is equivalent to instantly releasing the accelerator pedal when the power is lost.
The link control device 200 forms a power-off protection function through the first rotating arm 260, the first rotating disc 280 and the return device 300 arranged at the end part of the first rotating bar 281 of the first rotating disc 280, and is used for preventing potential safety hazards from possibly existing when the vehicle test device 100 is suddenly powered off and cannot work normally when the vehicle road condition simulation test is carried out, and the push rod 130 connected with the throttle is required to retract automatically and does not accelerate the vehicle any more. It will be readily appreciated that in the event of a power failure, the push rod 130 to which the brake is attached may be retracted from the way that braking action is no longer performed.
Preferably, a chamber structure 311 is disposed on the other side of the base 310, and the base 310 further includes an end cap 312. The end of the first rotation bar 281 and the end caps 312 are disposed on both sides of the chamber structure 311. The transfer shaft 330 includes a head 331 and a shaft body 332 connected to the head 331. The head 331 of the transfer shaft 330 can be magnetically attracted to the electromagnetic chuck 320. The shaft body 332 passes through the end of the first rotation bar 281, the chamber structure 311 and the end cap 312 in sequence. More preferably, the transmission shaft 330 moves in a horizontal direction, and a boss 333 is provided on the shaft body 332 in a radial direction, and the boss 333 is located in the chamber structure 311. The return device 300 further comprises a compression spring 340, wherein the compression spring 340 is sleeved on the shaft body 332, one end of the compression spring 340 abuts against the boss 333, and the other end abuts against the end of the first rotating bar 281. In the locked state of the return device 300, the head 331 of the transmission shaft 330 can be attached to the electromagnetic chuck 320 by magnetic force, and the compression spring 340 is compressed between the boss 333 and the end of the first rotation bar 281. When the electromagnetic chuck 320 is powered off, the electromagnetic chuck 320 loses magnetic force, the transmission shaft 330 rapidly moves towards the end cover 312 under the action of the restoring force of the pressure spring 340, that is, the head 331 of the transmission shaft 330 is far away from the electromagnetic chuck 320, the gap between the head 331 and the electromagnetic chuck 320 is larger than the thickness of the first rotating arm 260, and the return device 300 enters a release state. In one embodiment, the contact surfaces of the first rotating arm 260 and the head 331 of the transfer shaft 330 are both high hardness, high finish surfaces. When the electromagnetic chuck 320 loses the magnetic force, the compression spring 340 can generate a rapid horizontal displacement of the transmission shaft 330 with a small restoring force.
In the released state of the return device 300, the shaft body 332 of the transmission shaft 330 passes through the end cap 312 to form a protruding portion. When the vehicle testing device 100 is powered on again, the link control device 200 is powered on, the electromagnetic chuck 320 generates suction force, and at this time, the head 331 of the transmission shaft 330 is attracted to the electromagnetic chuck 320 by manually pressing the protruding portion, and the return device 300 returns to the locked state. In addition, before the return device 300 returns to the locked state, the first rotating arm 260 is returned to the original position, and after the return device 300 is locked, the subsequent test can be performed.
It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present application without departing from the spirit and scope of the application. Therefore, it is intended that the present application cover the modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.
