Description

Technical Field

[0001] This utility model relates to the field of automotive door parts technology, and in particular to an automotive sliding door opening conversion mechanism. Background Technology

[0002] The sliding door lock system is installed on the car door and mainly consists of an electronic control unit, a switching mechanism, a front lock, a rear lock, and a full unlock. The switching mechanism mainly controls the unlocking actions of the front lock, rear lock, and full unlock. The core of the sliding door system lies in its complex motion coordination mechanism—the door needs to disengage from the body locking structure before sliding laterally to open, and then be fixed at its maximum opening position after opening. This action relies heavily on the precise control of the conversion mechanism, which coordinates the interlocking relationships between the outer handle, inner handle, front lock, rear lock, full unlock, and child lock: ① When closing the door, pulling the inner / outer handle triggers the door closing microswitch and simultaneously opens the full unlock via the cable; once the door is closed and the front and rear locks are fully engaged, the safety button can be manually or electrically pushed into the locking state to ensure the door cannot be opened; ② When opening the door, pulling the inner / outer handle opens the front and rear locks via the cable; when the door is opened to its maximum limit, the full unlock will lock the door to prevent it from sliding; ③ When the child lock is engaged, the inner handle cannot open the front and rear locks, only the outer handle can open them; once the child lock is unlocked and the conversion mechanism safety is engaged, both the inner and outer handles can open the front and rear locks; when the conversion mechanism safety is engaged, neither the inner nor outer handles can open the front and rear locks. The existing conversion mechanisms have the following problems: ① Most existing conversion mechanisms are open structures, which easily accumulate dust and affect the flexibility of the mechanism; ② The child lock handle of the existing conversion mechanism is located on the side of the car door, making it impossible to open or close the child lock while driving; ③ The existing conversion mechanism does not have an anti-accidental touch function, and the car door can be opened directly after the handle is turned, which can easily cause accidents while driving. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes an automotive sliding door opening conversion mechanism. This mechanism includes a housing and, through an electric drive structure and a double-pull mechanism, enables the opening and closing of the child lock and the double-pull anti-accidental activation functions during driving.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model discloses a sliding door opening mechanism for automobiles, comprising: a base, a top cover, a child lock rotating arm, an inward opening handle, a first motor, a first opening rotating arm, a second opening rotating arm, and a third opening rotating arm.

The child lock swing arm is rotatably mounted on the base, with one end extending outward from the base and the other end slidably connected to one end of the child lock pin. The first motor is mounted on the base, and a first worm gear is provided on the shaft of the first motor. A transmission block matching the first worm gear is provided in the middle of the child lock swing arm, and the child lock swing arm is connected to the first worm gear via the first transmission block.

[0006] Furthermore, the base is provided with a safety rotating arm and a second motor. The second motor is fixedly installed on the base, and a second worm gear is provided on the output shaft of the second motor. The middle part of the safety rotating arm is rotatably connected to the base, one end of the safety rotating arm is slidably connected to the lower part of the safety pin shaft, and the other end of the safety rotating arm is provided with a transmission tooth. The second worm gear is connected to the transmission tooth on the safety rotating arm through a transmission gear.

[0007] Furthermore, a first protrusion is provided on one side of the third opening rotating arm, and the third opening rotating arm rests against one side of the safety rotating arm through the first protrusion.

[0008] Furthermore, the third opening rotating arm is provided with a double pull rotating arm, which is rotatably mounted on the third opening rotating arm. A return spring is provided between the double pull rotating arm and the third opening rotating arm. The third opening rotating arm is provided with a second protrusion.

If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0026] like Figures 1 to 8As shown, an embodiment of this utility model provides a car sliding door opening conversion mechanism, including: a base 1, a top cover 2, a child lock rotating arm 3, an inward opening handle 4, a first motor 5, a first opening rotating arm 6, a second opening rotating arm 7, and a third opening rotating arm 8. The base 1 and the top cover 2 are connected to each other. A first rotating shaft 9 is provided on the base 1. The first opening rotating arm 6, the second opening rotating arm 7, and the third opening rotating arm 8 are all mounted on the first rotating shaft 9. A child lock pin 10 is slidably mounted on the third opening rotating arm 8. A safety pin 11 is slidably mounted on the second opening rotating arm 7. The first opening rotating arm 6 is connected to the third opening rotating arm 8 through the child lock pin 10. The third opening rotating arm 8 is connected to the child lock pin 10 through... The safety pin 11 is connected to the second opening rotating arm 7, which is connected to the front and rear door locks via a cable. The inner opening handle 4 is mounted on the base 1 and is connected to the first opening rotating arm 6 via the first connecting rod 12. The child lock rotating arm 3 is rotatably mounted on the base 1, with one end extending outward from the base 1 and the other end slidably connected to one end of the child lock pin 10. The first motor 5 is mounted on the base 1, and the first worm gear 13 is provided on the shaft of the first motor 5. The child lock rotating arm 3 is provided with a transmission block 14 that matches the first worm gear 13 in the middle, and the child lock rotating arm 3 is connected to the first worm gear 13 via the first transmission block 14.

[0027] The conversion mechanism is installed on the car door, and the inner opening handle 4 is installed on the inside of the car door. The inner opening handle 4 can be moved to both sides on the base 1. When the direction of the inner opening handle 4 is the same as the opening direction of the car door, the first time it is moved, the inner opening handle 4 drives the first opening rotating arm 6 through the first connecting rod 12. The first opening rotating arm 6 drives the third opening rotating arm 8 to rotate synchronously through the child lock pin 10. In the locked state, the safety rotating arm 15 will drive the safety pin 11 to move upward. In this state, after the third opening rotating arm 8 rotates, because the safety pin 11 moves upward, the double pull rotating arm 19 cannot be pressed against the safety pin 11, and the third opening rotating arm 8 continues to rotate. After the rotation continues, the first protrusion 18 presses against the safety pin 11, causing the safety pin 11 to rotate and move downwards. Then, when the inward handle 4 is pulled in the opening direction for the second time, since the safety pin 11 has already moved downwards, the third opening arm 8 rotates and can press against the safety pin 11 through the double pull arm 19. The safety pin 11 drives the second opening arm 7 to rotate. After the second opening arm 7 rotates, it pulls the front lock and rear lock on the door through the cable, unlocking and opening the door. When the door is opened to the maximum position, the full unlock lock of the door will be connected to the vehicle, fixing the door in the maximum opening position.

[0028] When the car door needs to be closed, the inward handle 4 is pulled in the direction of closing the door. At this time, the inward handle 4 drives the fully open arm 22 to rotate through the second link 23. The fully open arm 22 pulls the fully open lock of the car door through the cable, so that the car door can slide freely after unlocking, thereby closing the car door. After the car door is closed, the second motor 16 drives the safety arm 15 through manual or program control, which moves the safety pin 11 upward, so that the inward handle 4 needs to be pulled twice to open the car door, realizing double pull unlocking and achieving the function of preventing accidental contact.

[0029] When there is a child in the vehicle, even with a double-pull anti-accidental-touch mechanism, the child can still unlock the door. In this case, the child lock function needs to be activated, meaning the door can only be opened via the outer door handle. The door can be opened by swinging the child lock arm 3. When the door is closed, the controller can control the first motor 5 to rotate, which in turn drives the child lock arm 3 to rotate via the first worm gear 13 and transmission block 14. After the child lock arm 3 rotates, it drives the child lock pin 10 to slide to the upper end of the groove of the third opening arm 8. At this time, the inner opening handle 4 drives the first opening arm 6 to rotate. Since the first opening arm 6 cannot be linked with the third opening arm 8 via the child lock pin 10, the inner opening handle 4 cannot open the door, thus realizing the child lock function. To deactivate the child lock function, the button controls the first motor 5 to reverse, causing the child lock arm 3 to move upward and slide the child lock pin 10 to the lower end of the groove of the third opening arm 8. At this time, the first opening arm 6 rotates and can be linked with the third opening arm 8 via the child lock pin 10, thus unlocking the door smoothly.

[0030] Specifically, such as Figure 2 , Figure 3 As shown, a safety rotating arm 15 and a second motor 16 are provided on the base 1. The second motor 16 is fixedly mounted on the base 1, and a second worm gear 17 is provided on the output shaft of the second motor 16. The middle part of the safety rotating arm 15 is rotatably connected to the base 1, one end of the safety rotating arm 15 is slidably connected to the lower part of the safety pin 11, and the other end of the safety rotating arm 15 is provided with a transmission gear. The second worm gear 17 is connected to the transmission gear on the safety rotating arm 15 through a transmission gear. The second motor 16 can drive the safety rotating arm 15 to swing, thereby controlling the position of the safety pin 11.

[0031] In a specific embodiment, such as Figure 6 As shown, a first protrusion 18 is provided on one side of the third opening rotating arm 8, and the third opening rotating arm 8 rests against one side of the safety rotating arm 15 through the first protrusion 18. This allows the safety rotating arm 15 to rotate together with the third opening rotating arm 8 through the first protrusion 18, causing the safety pin 11 to move downward.

[0032] In a specific embodiment, such as Figure 4 , Figure 5 , Figure 6As shown, the third opening rotating arm 8 is provided with a double pull rotating arm 19. The double pull rotating arm 19 is rotatably mounted on the third opening rotating arm 8, and a return spring 20 is provided between the double pull rotating arm 19 and the third opening rotating arm 8. The third opening rotating arm 8 is provided with a second protrusion 21. The double pull rotating arm 19 is locked on one side of the second protrusion 21 by the return spring 20, and the third opening rotating arm 8 is pushed against one side of the safety pin 11 by the double pull rotating arm 19. Both the second opening arm 7 and the safety arm 15 are provided with grooves, and the safety pin 11 can slide on the grooves. After the second motor 16 rotates, it can drive the safety arm 15 to rotate through the transmission gear, thereby pushing the safety pin 11 to move in the groove of the second opening arm 7. When the safety pin 11 is located at the upper part of the groove of the second opening arm 7, the third opening arm 8 cannot contact the safety pin 11 through the double pull arm 19 after rotating. The third opening arm 8 can only continue to rotate. After rotating, the first protrusion 18 contacts the safety arm 15 and pushes the safety arm 15 to rotate, so that the safety pin 11 slides to the lower part of the groove of the second opening arm 7. After releasing the inner opening handle 4 and pulling the inner opening handle 4 again, the third opening arm 8 can push the safety pin 11 through the double pull arm 19, causing the second opening arm 7 to swing, thereby unlocking the front and rear locks of the door through the cable.

[0033] Preferably, the transmission teeth on the second worm gear 17 and the safety arm 15 are helical teeth, so that after the safety arm 15 is pushed by the third opening arm 8, it can drive the transmission gear and the second worm gear 17 to rotate, avoiding the self-locking phenomenon of the worm gear. The first worm gear 13 and the transmission block 14 also adopt the same design, so that when the child lock arm 3 is manually turned, the first worm gear 13 can also be driven.

[0034] Specifically, such as Figure 7 As shown, a fully openable rotating arm 22 is provided on the first rotating shaft 9. The middle part of the fully openable rotating arm 22 is rotatably connected to the first rotating shaft 9. One end of the fully openable rotating arm 22 is connected to the inner opening handle 4 through the second connecting rod 23, and the other end of the fully openable rotating arm 22 is connected to the fully unlocked lock on the car door through the cable. The fully openable rotating arm 22 is used to release the fully unlocked lock when the car door is closed. The fully openable rotating arm 22 is provided with a sliding groove. When the inner opening handle 4 is turned in the same direction as the car door opening direction, the second connecting rod 23 only slides in the sliding groove, and the fully openable rotating arm 22 does not rotate. Only when the inner opening handle 4 is turned in the same direction as the car door closing direction can the second connecting rod 23 drive the fully openable rotating arm 22 to rotate, thereby unlocking the fully unlocked lock on the car door and allowing the car door to rotate freely.

[0035] In a preferred embodiment, such as Figure 7 , Figure 8As shown, the first pivot 9 is rotatably mounted with an emergency pivot 25 and an outward-opening pivot 26. The emergency pivot 25 is connected to the third opening pivot 8 via a third protrusion 27, and the outward-opening pivot 26 is connected to the fully opening pivot 22 via a fourth protrusion 28. The outward-opening pivot 26 is also connected to the second opening pivot 7 via a safety pin 11. The emergency unlocking handle is connected to the emergency pivot 25 via a cable. After pulling the emergency unlocking handle, the emergency pivot 25 can drive the third opening pivot 8 to rotate, achieving double-pull unlocking. The outward-opening pivot 26 is connected to the opening handle on the outside of the door. After pulling the outward-opening pivot 26 via the external opening handle, if the safety pin 11 is located at the upper part of the slide groove of the second connecting rod 23, the outward-opening pivot 26 cannot drive the second opening pivot 7. Only when the safety pin 11 is located at the lower part of the slide groove of the second connecting rod 23 can the outward-opening pivot 26 rotate to drive the second opening pivot 7 and the fully opening pivot 22 to rotate, thus unlocking the door.

[0036] In one specific embodiment, the base 1 is provided with multiple signal switches 29 so that the controller can obtain the status of the child lock rotating arm 3, the safety rotating arm 15, the first opening rotating arm 6, and the fully opening rotating arm 22, so as to facilitate monitoring the status of the car door.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
