[0069] Figure 1 A schematic diagram showing the structure of a vehicle sunroof control button actuation system according to an embodiment of the present invention Figure 1 .

[0070] Figure 2 A schematic diagram showing the structure of a vehicle sunroof control button actuation system according to an embodiment of the present invention Figure 2 . Figure 3 yes Figure 2 Vertical cross-sectional view. Figure 4 yes Figure 2 As shown in the figure, a vehicle sunroof control button actuation system 100 includes a cylinder body 101, a first cylinder 102, a second cylinder 103, a gear 104 and a connecting assembly 105.

[0071] The first cylinder 102 and the second cylinder 103 are formed on the cylinder body 101. The first cylinder 102 has a first piston rod 106 running through it, and a first rack 107 is fixedly arranged at one end of the first piston rod 106. When the first cylinder 102 is working, the first piston rod 106 can drive the first rack 107 to move forward and backward in the length direction of the first piston rod 106. The second cylinder 103 has a second piston rod 108 running through it, and a second rack 109 is fixedly arranged at one end of the second piston rod 108. When the second cylinder 103 is working, the second piston rod 108 can drive the second rack 109 to move forward and backward in the length direction of the second piston rod 108. The structures of the first cylinder 102 and the second cylinder 103 are basically the same, and both can work independently.

[0072] The gear 104 is fixed to the cylinder body 101 by rotational cooperation through the gear 104 shaft. When the first cylinder 102 is actuated, the first piston rod 106 extends outward, and the first rack 107 is connected and cooperated with the gear 104 and drives the gear 104 to rotate from the initial position to the first direction. When the first piston rod 106 is retracted, the first rack 107 drives the gear 104 to rotate in the second direction so that the gear 104 returns to the initial position, and the first rack 107 continues to be retracted and disengaged from the gear 104. Similarly, when the second cylinder 103 is actuated, the second piston rod 108 extends outward, and the second rack 109 is connected and cooperated with the gear 104 and drives the gear 104 to rotate from the initial position to the second direction. When the second piston rod 108 is retracted, the second rack 109 drives the gear 104 to rotate in the first direction so that the gear 104 returns to the initial position, and the second rack 109 continues to be retracted and disengaged from the gear 104. It is easy to understand that the first direction and the second direction are opposite directions to each other. Figure 4The first rack 107 extends outward (to the right), driving the gear 104 to rotate in the clockwise direction of the paper, where the clockwise direction is the first direction. When the second piston rod 108 is retracted, it drives the gear 104 to rotate in the counterclockwise direction of the paper, where the counterclockwise direction is the second direction. In this embodiment, the first cylinder 102 and the second cylinder 103 work separately. When the first cylinder 102 is working, the second cylinder 103 is not working. The first cylinder 102 drives the gear 104 to rotate from the initial position to the first position along the first direction, and then returns from the first position to the initial position, which is equivalent to the first gear 104 rotating a set angle in the first direction, and then rotating the same angle in the second direction, and then the gear 104 returns to the initial position. Similarly, when the second cylinder 103 is working, the first cylinder 102 is not working, and the second cylinder 103 drives the gear 104 to rotate from the initial position to the second position along the second direction, and then returns from the second position to the initial position, which is equivalent to the gear 104 rotating a set angle in the second direction, and then rotating the same angle in the first direction, and then the gear 104 returns to the initial position. The first cylinder 102 and the second cylinder 103 complete the position switching of the gear 104 between the first position, the initial position and the second position.

[0073] refer to Figure 3 and Figure 4, the connecting assembly 105 includes a connecting plate 111 and a rotating hoop 112. The connecting plate 111 is fixed on the gear 104, and the rotation of the gear 104 drives the connecting plate 111 to rotate synchronously. The top of the rotating hoop 112 can be fixed with the car sunroof control button, and the bottom of the rotating hoop 112 is fixed with the connecting plate 111, and the rotation axis of the gear 104 coincides with the rotation axis of the rotating hoop 112. In this way, the rotation of the connecting plate 111 is transmitted to the car sunroof control button through the rotating hoop 112. Therefore, a linkage is formed between the gear 104, the connecting plate 111, the rotating hoop 112 and the car sunroof control button. The first cylinder 102 and the second cylinder 103 respectively drive the first rack 107 and the second rack 109 to move, thereby driving the gear 104 to rotate, and the gear 104 drives the car sunroof control button to rotate through the connecting plate 111 and the rotating hoop 112. Since the first cylinder 102 can drive the gear 104 through the first rack 107 to complete the position switching among the initial position → the first position → the initial position, accordingly, the gear 104 can drive the car sunroof control button to synchronously complete the position switching among the initial position → the first position → the initial position. When the car sunroof control button reaches the first position, it can trigger the car sunroof to work, such as opening the car sunroof. Similarly, the second cylinder 103 can drive the gear 104 through the second rack 109 to complete the position switching among the initial position → the second position → the initial position, accordingly, the gear 104 can drive the car sunroof control button to synchronously complete the position switching among the initial position → the second position → the initial position. When the car sunroof control button reaches the second position, it can trigger the car sunroof to work, such as closing the car sunroof.

[0074] The pneumatic structure in the automobile sunroof control button actuation system 100 provided by the present invention controls the automobile sunroof control button to switch between the first position, the initial position and the second position through the first cylinder 102 and the second cylinder 103, thereby completing the opening and closing of the automobile sunroof, which can effectively improve the test effect.

[0075] Preferably, the first piston rod 106 and the second piston rod 108 are arranged in parallel. The teeth of the first rack 107 and the second rack 109 are arranged opposite to each other, and the first rack 107 and the second rack 109 are arranged on both sides of the radial direction of the gear 104, and can be engaged or disengaged with the gear 104 respectively to drive the gear 104 to rotate in the first direction or the second direction.

[0076] Preferably, one end of the first piston rod 106 has an external thread, a corresponding threaded hole is formed on the first rack 107, and the first piston rod 106 is threadedly fixed to the first rack 107. Similarly, one end of the second piston rod 108 has an external thread, a corresponding threaded hole is formed on the second rack 109, and the second piston rod 108 is threadedly fixed to the second rack 109. The first rack 107 and the second rack 109 are fixed to one end of the first piston rod 106 and the second piston rod 108, respectively, and are fixed by fixing nuts.

[0077] Preferably, the automobile sunroof control button actuation system 100 further includes a first adjusting nut 113 for limiting the maximum travel of the first rack 107. The first adjusting nut 113 is threadedly matched and fixed with the other end of the first piston rod 106. Figure 4 When the first piston rod 106 moves from left to right, the first rack 107 moves rightward from its initial position, the first adjusting nut 113 moves rightward, and finally abuts against the outer side of the first cylinder 102, and the first piston rod 106 stops moving. At this time, the first rack 107 reaches its farthest travel position, and the first rack 107 can drive the gear 104 to reach its first position. Therefore, the position of the first adjusting nut 113 on the first piston rod 106 can be adjusted according to the first position to be reached by the gear 104. In the initial state, the first rack 107 does not extend. If the distance between the first adjusting nut 113 and the outer side of the first cylinder 102 is larger, the first rack 107 reaches its farthest travel position relatively far away, and the rotation angle of the gear 104 to reach the first position is larger. If the distance between the first adjusting nut 113 and the outer side of the first cylinder 102 is closer, the first rack 107 reaches its farthest travel position relatively close, and the rotation angle of the gear 104 to reach the first position is smaller. Specifically, the distance between the first adjusting nut 113 and the outer side of the first cylinder 102 needs to be set according to the rotation angle of the automobile sunroof control button to trigger the opening action, that is, the farthest distance reached by the first rack 107 is determined by the rotation angle, and the specific position of the first adjusting nut 113 is set according to the farthest distance. Therefore, the automobile sunroof control button actuation system 100 is applicable to various automobile sunroof control buttons that trigger the opening action at different rotation angles.

[0078] Preferably, the automobile sunroof control button actuation system 100 further includes a second adjusting nut 114. The second adjusting nut 114 is disposed on the first piston rod 106 and is located between the first cylinder 102 and the first rack 107. The distance between the second adjusting nut 114 and the first rack 107 is adjusted to limit the shortest stroke of the first rack 107. The second adjusting nut 114 is threadedly matched and fixed to the first piston rod 106. Figure 4When the gear 104 returns to the initial position from the first position, the first piston rod 106 moves from right to left, the first rack 107 moves to the left from the farthest position, and the second adjusting nut 114 moves to the left, and finally abuts against the other side of the outside of the first cylinder 102, so that the first piston rod 106 stops moving. At this time, the first rack 107 just disengages from the gear 104, so that the gear 104 returns to its initial position.

[0079] Preferably, the automobile sunroof control button actuation system 100 further includes a third adjustment nut 115, which operates in the same manner as the first adjustment nut 113, so as to limit the farthest stroke of the second rack 109. The automobile sunroof control button actuation system 100 further includes a fourth adjustment nut 116, which operates in the same manner as the second adjustment nut 114, so as to limit the closest stroke of the second rack 109. It should be noted that the first, second, third, and fourth stroke adjustment nuts generally include an adjustment nut and a fixing nut. During the adjustment process, the fixing nut can be loosened first, and after adjusting the left and right positions of the adjustment nut, the fixing nut can be rotated to fix the positions of the respective adjustment nuts.

[0080] Preferably, the automobile sunroof control button actuation system 100 further includes a screw 117. Figure 3 The connecting plate 111 is fixed to the gear 104 by screws 117, and the rotation of the gear 104 can drive the connecting plate 111 to rotate. The rotation axis of the connecting plate 111 coincides with the rotation axis of the rotating hoop 112.

[0081] Preferably, the automobile sunroof control button actuation system 100 further includes a pin 118. Figure 1 and Figure 4 A waist-shaped groove 119 is provided on the connecting plate 111, and a mounting hole is provided on the rotating clamp 112. The pin 118 passes through the mounting hole and falls into the waist-shaped groove 119. The pin 118 is used to fix the relative position of the connecting plate 111 and the rotating clamp 112. The rotating clamp 112 with different structures is selected to adapt to different car sunroof control buttons.

[0082] Figure 5A The present invention shows a structural schematic diagram of a car sunroof control button in the prior art. Figure 5B A schematic diagram of the structure of the cooperation between the rotating clamp and the car sunroof control button is shown. Figure 5C A schematic diagram showing the cooperation between the rotating clamp and the car sunroof control button from a top view angle is shown. Figure 5D yes Figure 5C BB section view. Figure 3As shown, the car sunroof control button 120 has a long strip protrusion 121 protruding downward. It is easy to understand that the opening shape of the corresponding rotating clamp 112 matches the outer shape of the long strip protrusion 121. The conventional embedded clamp is formed by the left and right half pieces 122 being matched and connected. The rotating clamp 112 here can also be understood as the left and right half pieces 122 in a semicircular shape. Figure 5C The tail ends of the two half pieces 122 are connected, and the head of the two half pieces 122 each forms a mounting ear 123 for mounting the corresponding screw. When the long strip convex block 121 falls into the opening formed by the two half pieces 122, the screw is tightened, and the two half pieces 122 are tightened close to the opening, so that the periphery of the convex block is matched and fixed with the opening. Figure 4 As shown, because the pin 118 cooperates with the waist-shaped groove 119, the connecting plate 111 is inserted into the pin 118 and fixed through its waist-shaped groove 119. In this embodiment, four pins 118 and four corresponding waist-shaped grooves 119 are provided, and the rotation centers of the four pins 118 are coaxial with the center of the rotating hoop 112, so that the gear 104, the connecting plate 111 and the rotating hoop 112 are all coaxial, and in the process of the gear 104 rotating to drive the automobile sunroof control button 120, the rotating hoop 112 will not fail or get stuck due to the center offset.

[0083] Fig. 6A The present invention shows a structural schematic diagram of a car sunroof control button in the prior art. Figure 6B A schematic diagram of the structure of the cooperation between the rotating clamp and the car sunroof control button is shown. Figure 6C A schematic diagram showing the cooperation between the rotating clamp and the car sunroof control button from a top view angle is shown. Fig.6D yes Figure 6C CC section view. Combined Figure 3 As shown, another automobile sunroof control button 120' has a truncated cone 124 protruding downward. It is easy to understand that the top surface of the corresponding rotating hoop 112 forms a notch that matches the outer shape of the truncated cone 124. When the boss falls into the notch, tighten the screws, and the two half pieces 122 are tightened close to the notch so that the notch and the outer periphery of the truncated cone 124 are matched and fixed. During the tightening process of the rotating hoop 112', the pin 118 cooperates with the waist-shaped groove 119. In this embodiment, four pins 118 and corresponding four waist-shaped grooves 119 are provided, and the rotation center of the four pins 118 is coaxial with the center of the rotating hoop 112', so that the gear 104, the connecting plate 111 and the rotating hoop 112' are all coaxial, and in the process of the gear 104 rotating to drive the automobile sunroof control button 120', the rotating hoop 112' will not fail or get stuck due to center offset.

[0084] In addition to the above-mentioned rotating control buttons, there are also toggle control buttons on the market, and the automobile sunroof control button actuation system 100 provided by the present invention is still applicable.

Figure 8B yes Fig. 8A A partial cross-sectional view of . Preferably, the automobile sunroof control button actuation system 100 also includes a first lever 125 and a second lever 126. A first long groove 127 and a second long groove 128 are provided on the bottom surface of the cylinder body 101. Among them, one end of the first lever 125 passes through the first long groove 127 and is fixed to the first rack 107, and one end of the second lever 126 passes through the second long groove 128 and is fixed to the second rack 109. The other end of the first lever 125 and the other end of the second lever 126 are arranged relatively spaced apart. The first piston rod 106 drives the first lever 125 to move through the first rack 107, and the second piston rod 108 drives the second lever 126 to move through the second rack 109. The other end of the first lever 125 and the other end of the second lever 126 are used to control a toggle-type button. Reference Fig. 7A The automobile sunroof control button 120" has a short strip protrusion 129 protruding downward, and the other end of the first lever 125 and the other end of the second lever 126 are respectively arranged on both sides of the short strip protrusion 129. The first cylinder 102 and the second cylinder 103 respectively drive the first lever 125 or the second lever 126 to move, so as to push the short strip protrusion 129 to move leftward or rightward to realize opening or closing of the sunroof.

[0085] For further reference, Figure 8B, one end of the first rack 107 is connected to the adjusting stud 130, and the adjusting stud 130 is provided with a fifth adjusting nut 131. In the initial state, the first rack 107 moves to the rightmost end, and the fifth adjusting nut 131 protrudes outside the cylinder body 101. The first lever 125 and the second lever 126 are arranged on both sides of the short strip protrusion 129. In the working state, the first rack 107 moves to the left, and the fifth adjusting nut 131 moves closer to one side of the cylinder body 101. When it is attached to the cylinder body 101, the first lever 125 pushes the short strip protrusion 129 from the initial position to the starting position, and the sunroof opens. When the first rack 107 moves to the right, the short strip protrusion 129 loses thrust and automatically returns to the initial position. Similarly, in the initial state, the second rack 109 moves to the leftmost end. In the working state, the second rack 109 moves to the right, and the third adjusting nut 115 moves closer to the side of the cylinder body 101. When it is close to the cylinder body 101, the second lever 126 pushes the short strip protrusion 129 from the initial position to the closed position, and the sunroof is closed. When the second rack 109 moves to the left, the short strip protrusion 129 loses its thrust and automatically returns to the initial position. Since the stroke of the toggle type control button is shorter than that of the rotation type, a stroke adjustment sleeve can be set at the other end of the second rack 109 as needed, which is equivalent to shortening the stroke of the third adjusting nut 115.

[0086] Return to Figure 4 An air inlet hole 132 is provided at the end of the first cylinder 102 and the second cylinder 103. The first cylinder 102 and the second cylinder 103 are bidirectionally controlled through the air inlet hole 132 to control the initial stroke position and reciprocating motion of the first piston rod 106 and the second piston rod 108. The first cylinder 102 and the second cylinder 103 work independently without interfering with each other.

Preferably, the automobile sunroof control button actuation system 100 also includes a fixing mechanism 133. The fixing mechanism 133 includes an adjustable connecting rod 134, a fixing plate 135 and a suction cup 136. The fixing plate 135 is arranged at one end of the adjustable connecting rod 134, and the fixing plate 135 can be fixedly connected to the cylinder by a screw 117. The suction cup 136 is arranged at the other end of the adjustable connecting rod 134, and the suction cup 136 is used to be adsorbed on the windshield. The two ends of the adjustable connecting rod 134 are universally connected to the fixing plate 135 and the suction cup 136 respectively. In this way, the automobile sunroof control button actuation system 100 can be conveniently fixed in the working position, thereby improving its working efficiency.
