[0046] Nowadays, many car owners set parking locks on their parking spaces to prevent others from occupying the parking spaces. In the related art, when the parking lock is in the blocking state, the blocking component of the parking lock is knocked down or flipped under the action of external force. At this time, in order to restore the blocking state, the blocking component needs to be driven by the power of the battery to drive the drive device to start and restore the blocking state.

[0048] An embodiment of a first aspect of the present application provides a control device for a vehicle blocking member, comprising a rotating shaft 100 , a deflection device 200 , a transmission device 300 and a power source 400 .

[0049] The rotating shaft 100 can be rotatably arranged around a pivot axis;

[0050] The deflection device 200 includes a spring 210 and a deflection mechanism 220. The deflection mechanism 220 has two springs 210 and is spaced apart from each other and is rotatably connected to the rotation shaft 100. The spring 210 is sleeved on the rotation shaft 100, and opposite ends of the spring 210 are respectively connected to the deflection mechanism 220.

[0051] The transmission device 300 includes a worm wheel 320 and a worm 310. The worm wheel 320 is sleeved on the spring 210. The worm wheel 320 is fixed to the two deflection mechanisms 220 respectively. The worm 310 is in transmission connection with the worm wheel 320.

[0052] The power source 400 is connected to the worm 310 to drive the worm 310 to rotate forward and reverse.

[0053] like Figure 1 As shown, under normal use, that is, the owner unlocks or locks the parking lock through remote control, the power source 400 drives the worm 310 to rotate forward and reverse, so that the worm 310 is connected to the turbine transmission, and the turbine also rotates, causing the deflection mechanism 220 to rotate. Under the action of the deflection mechanism 220, the rotation of the shaft 100 is realized.

[0054] In an abnormal state, that is, when the blocking member is hit, an unconventional flip occurs. Since the blocking member rotates synchronously with the rotating shaft 100, the rotating shaft 100 starts to rotate with the blocking member, and then the rotating shaft 100 drives the deflection mechanism 220 to rotate together under the restriction of the deflection mechanism 220. At this time, the deflection mechanism 220 compresses the spring 210, so that the spring 210 generates a force on the deflection mechanism 220, and the direction of the force is along the length direction of the rotating shaft 100. When the blocking member is free from interference or disturbance, the force generated by the spring 210 on the deflection mechanism 220 is released, so that the deflection mechanism 220 drives the rotating shaft 100 to rotate, so that the blocking member returns to the blocking position. In this way, the power consumption of the battery can be effectively reduced, thereby slowing down the frequency of battery replacement or charging, so that the owner does not need to frequently replace or charge the battery, which brings convenience to the owner. And it can be matched through a purely mechanical structure, with a compact structure and no manual operation required.

[0055] like Figure 1 As shown, the length direction of the worm 310 is perpendicular to the pivot axis of the rotating shaft 100. The pivot axis of the turbine is coaxial with the pivot axis of the rotating shaft 100. For example, when the turbine rotates, the two deflection mechanisms 220 are synchronously driven to rotate.

[0056] In some examples, the deflection mechanism 220 includes a top block 221, a reed tube 222 and a stop pin 223. The reed tube 222 is sleeved on the spring 210, and the top block 221 is slidably disposed on the reed tube 222. The top block 221 abuts against the spring 210. A ring-shaped cam structure 224 is disposed on the surface of the top block 221 facing away from the spring 210. The stop pin 223 is inserted into the rotating shaft 100, and the opposite ends of the stop pin 223 extend out of the rotating shaft 100. The opposite ends of the stop pin 223 are slidably connected to the ring-shaped cam structure 224.

[0057] like Figures 3 to 6 As shown, the two deflection mechanisms 220 are connected through the turbine, so that the rotating shaft 100 and the spring 210 can pass through.

[0058] The top block 221 has a main body in the shape of a rectangular parallelepiped, and the outer corner position is set as a rounded corner. The reed tube 222 has a main body in the shape of a rectangular parallelepiped, and its outer corner position is set as a rounded corner, so that it is conducive to the sliding of the top block 221 in the reed tube 222, reducing the friction between the two, and making the top block 221 slide more smoothly. The size of the top block 221 is slightly smaller than the size of the reed tube 222, so that the top block 221 can slide in the reed tube 222, but will not rotate in the reed tube 222. In this way, when the reed tube 222 rotates, the top block 221 will also rotate with the reed tube 222.

[0059] An annular cam structure 224 is provided on the surface of the top block 221 facing away from the spring 210 . The annular cam structure 224 can slide in the spring tube 222 through sliding cooperation with the stop pin 223 , thereby further compressing the spring 210 .

[0060] For example, when the top block 221 slides in the spring tube 222, the top block 221 slides along the length direction of the spring tube 222, and then compresses the spring 210 in the length direction of the spring 210, so that the spring 210 gives the top block 221 a force in the length direction of the spring 210. When the blocking member is separated from the collision source or interference source, the rotating shaft 100 can rotate. At this time, the compressed spring 210 stretches and pushes the top block 221. The annular cam structure 224 of the top block 221 and the stop pin 223 slide in cooperation, driving the rotating shaft 100 to rotate.

[0061] In some examples, the stop pin 223 is perpendicular to the pivot axis of the shaft 100 .

[0062] like Figures 1 to 6 As shown, the stop pin 223 is perpendicular to the pivot axis of the rotating shaft 100 , which is beneficial for both opposite ends of the stop pin 223 to cooperate with the annular cam structure 224 , so that both opposite ends of the stop pin 223 can cooperate with the annular cam structure 224 .

[0063] In some examples, the annular cam structure 224 includes two protruding members 2241 disposed on the surface of the top block 221 facing away from the spring 210, the two protruding members 2241 are connected end to end to form a rotationally symmetrical structure, and a receiving recess 2242 is formed at the connection of the two protruding members 2241;

[0064] The two opposite ends of the stop pin 223 are slidably connected to the two protruding components 2241 , so that the top block 221 and the stop pin 223 are inclined to cooperate with each other, so that the top block 221 slides relative to the spring tube 222 , thereby compressing the spring 210 .

[0065] like Figure 7 and Figure 8 As shown, the middle position of the protruding member 2241 is protruding and is the highest position, and both ends of the protruding member 2241 gradually tilt downward. The accommodating recess 2242 is located at the lowest position of the protruding member 2241.

[0066] For example, when the rotating shaft 100 or the deflection mechanism 220 does not rotate, the stop pin 223 stops on the accommodating recess 2242. At this time, the top block 221 will not slide toward the spring tube 222, and the spring 210 is also in the initial state.

[0067] For another example, when the rotating shaft 100 rotates relative to the deflection mechanism 220, the stop pin 223 will slide on the protruding member 2241, that is, gradually slide from the accommodating recess 2242 toward the middle position of the protruding member 2241. Since the protruding member 2241 protrudes from the surface of the top block 221, the stop pin 223 cooperates with the protruding member 2241 to drive the top block 221 to slide toward the spring tube 222, thereby compressing the spring 210.

[0068] In some examples, the protruding member 2241 has a first curved surface 2241a, a transition plane 2241b, a contact surface 2241c, and a second curved surface 2241d connected in sequence, the transition plane 2241b is perpendicular to the contact surface 2241c, the slope of the first curved surface 2241a is greater than the slope of the second curved surface 2241d, and the arc length of the first curved surface 2241a is greater than the arc length of the second curved surface 2241d;

[0069] When the deflection device 200 rotates around the first rotation direction, one end of the stop pin 223 slides along the first curved surface 2241a, the transition plane 2241b, and the second curved surface 2241d;

[0070] When the deflection device 200 rotates around the second rotation direction, one end of the stop pin 223 slides along the second curved surface 2241d and finally abuts against the abutting surface 2241c.

[0071] like Figures 7 to 10 As shown, the slope of the first curved surface 2241a is greater than the slope of the second curved surface 2241d, and the arc length of the first curved surface 2241a is greater than the arc length of the second curved surface 2241d. In this way, the time spent by the stop pin 223 on the first curved surface 2241a is longer than the time spent by the stop pin 223 on the second curved surface 2241d, so that the stop pin 223 slides slowly on the first curved surface 2241a, thereby slowing down the rotation rate of the rotating shaft 100 and preventing the vehicle blocking component from flipping too fast.

[0072] like Figure 7 , Figure 8 and Fig. 9 As shown, the first rotation direction is Fig. 9The stop pin 223 slides along the first curved surface 2241a, the transition plane 2241b, and the second curved surface 2241d. When the stop pin 223 slides on the first curved surface 2241a and the transition plane 2241b, it drives the top block 221 to slide toward the spring tube 222, thereby compressing the spring 210. Then, the stop pin 223 falls from the transition plane 2241b into the second curved surface 2241d, and quickly slides along the second curved surface 2241d to the accommodating recess 2242. In this process, the force of the spring 210 on the top block 221 causes the top block 221 to quickly slide back to the spring tube 222. In this way, the stop pin 223 realizes the rotation of the rotating shaft 100 by continuously cooperating with the cam member.

[0073] like Figure 7 , Figure 8 and Fig.10 As shown, the second rotation direction is Fig.10 The clockwise direction of the angle shown in . One end of the stop pin 223 slides along the second curved surface 2241d and abuts against the abutting surface 2241c. In this way, the stop pin 223 drives the top block 221 to slide toward the spring tube 222. After the spring 210 is compressed, the cam component will limit the stop pin 223 from continuing to rotate, thereby limiting the rotation of the shaft 100. This is beneficial to protecting the power source 400, so that the power source 400 will not be rotated under external forces and cause internal damage. The above state mostly occurs when the parking lock is not in normal use. When the parking lock's blocking component is separated from the interference or collision source, the force of the spring 210 on the top block 221 causes the top block 221 to slide back to the spring tube 222, thereby rotating the stop pin 223 and driving the shaft 100 to rotate, so that the blocking component returns to the blocking position.

[0074] In addition, during abnormal use, when the car blocking component is forcibly pulled down, the parking lock can be prevented from being damaged and the entire product will not fail.

[0075] In some examples, the diameter of the stop pin 223 is smaller than the height of the abutment surface 2241c. This configuration can prevent the stop pin 223 from turning over the abutment surface 2241c from the second curved surface 2241d.

[0076] In some examples, a receiving groove 2211 is provided at one end of the top block 221 close to the spring 210, the bottom wall of the receiving groove 2211 is provided with an arc-shaped narrowing groove 2212, and the four side walls of the receiving groove 2211 are provided with a fitting groove 2213, and there is an arc transition between the fitting groove 2213 and the arc-shaped narrowing groove 2212, and the fitting groove 2213 is extended along the length direction of the top block 221.

[0077] like Figures 11 to 13As shown, the receiving groove 2211 is used to receive the spring 210. The arc-shaped narrowing groove 2212 is used to increase the friction between the spring 210 and the top block 221, and fix the position of the spring 210 in the top block 221. The fitting groove 2213 is used to abut against the outer peripheral surface of the spring 210, so as to increase the friction between the side wall of the top block 221 and the outer peripheral surface of the spring 210, which is beneficial to the transmission of the deflection mechanism 220 and the rotating shaft 100.

[0078] In some examples, the distance between the two oppositely disposed fitting grooves 2213 gradually decreases from the opening of the receiving groove 2211 toward the arc-shaped narrowing groove 2212. Figures 11 to 13 As shown, the side wall of the top block 221 abuts against the outer peripheral surface of the spring 210, thereby increasing the friction between the two, which is beneficial to the transmission between the deflection mechanism 220 and the rotating shaft 100.

[0079] In some examples, the power source 400 includes a protection box and a motor. The protection box is disposed on one side of the rotating shaft 100 , and the motor is disposed in the protection box. The motor is connected to the worm 310 through a gear transmission mechanism.

[0080] like Figure 1 and Figure 2 As shown, the output shaft of the motor is connected to the worm 310 through a gear transmission mechanism, so as to drive the worm 310. The protection box can effectively protect the motor and play a waterproof role, and the control panel for receiving remote control commands is also arranged in the protection box.

[0081] In addition, a buzzer is provided on the protection box, and the buzzer is electrically connected to the control panel. When the parking lock is in an abnormal use state, the buzzer will emit a warning sound.

[0084] The control device of the embodiment of the first aspect of the present application, the control device is arranged on the base;
