Description

Technical Field

[0001] The present application relates to the technical field of passenger vehicle switch devices, and in particular to an anti-tripping passenger vehicle trunk lid switch and a method of using the same. Background Art

[0002] Passenger cars are vehicles for people to ride in. In terms of design and technical characteristics, they are mainly used to carry passengers and carry-on luggage or temporary items. According to national standards, passenger cars can be divided into sedans, multi-purpose vehicles, sports utility vehicles, special passenger cars and crossover passenger cars. Special passenger cars generally refer to passenger cars with professional purposes such as ambulances and funeral cars.

[0003] The passenger car trunk lid switch, also known as the tailgate lock, is a device installed on the trunk lid that can lock the car trunk and open it through its internal structure. It is a very important car body accessory with a safety protection function. It must ensure that the door is reliably locked during normal use and prevent accidental opening, and ensure that the door can be opened smoothly when it needs to be opened.

[0004] In view of the above-mentioned related technologies, in the prior art, the tailgate lock fixes the lock buckle by engaging a single ratchet with a hook, and uses a spring to energize the hook and the ratchet. When the hook is disengaged from the ratchet, the ratchet releases the lock buckle to unlock the tailgate lock. However, the hook of this method is prone to disengagement, making it difficult for the ratchet to engage with the hook, which in turn makes it difficult to lock the lock buckle, resulting in the trunk lid being unable to be closed smoothly, and even the possibility of accidentally opening the trunk lid while driving. Summary of the invention

[0006] Furthermore, the pawl assembly includes a guide block located inside the switch housing, the guide block is rotatably connected to the switch housing, a hook is provided at one end of the guide block near the ratchet, an extension rod is provided at one end of the guide block near the hook, one end of the extension rod extends to the position of the fixed plate, and a side top plate is provided at the end of the extension rod extending to the fixed plate, and the side top plate abuts against the lower end of the wrench.

[0007] Furthermore, an electric drive assembly with a built-in telescopic rod is provided on the outer side of the switch housing, and the electric drive assembly is fixedly mounted on a fixed plate and close to a side top plate, and the side top plate is located within the travel range of the telescopic rod of the electric drive assembly.

[0008] Furthermore, a limiting slot is provided on the first rotating rod near the side top plate, and a driving motor is provided on the outer side of the first rotating rod near the limiting slot. The driving motor is fixedly installed inside the switch housing, and the output end of the driving motor is plugged into the limiting slot.

[0009] Furthermore, a first limit block is provided on the inner wall of the slide slot, and the first limit block is located at the corner of the slide slot. A second limit block is provided on the inner wall of the push rod and close to the first limit block. The first limit block is rotatably connected to the push rod, and a return torsion spring is provided between the first limit block and the push rod. The second limit block is also rotatably connected to the push rod, and another return torsion spring is provided between the second limit block and the push rod.

[0010] A method for using the above-mentioned anti-tripping passenger car trunk lid switch comprises the following steps: S1. Locking, so that the lock ring and the ratchet wheel are close to each other, the lock ring drives the ratchet wheel to rotate, and the ratchet wheel drives the guide block and the stop block to rotate. When the ratchet wheel can engage with the hook and the stop block, the guide block rotates under the action of the ratchet torsion spring, and the stop block rotates under the action of the second tension spring. The hook and the stop block engage with the slot on the ratchet wheel at the same time, and the ratchet wheel is doubly locked; S2. Open the single lock anti-drop buckle, and after the ratchet and the stopper are engaged and connected, press the pull rod downward to allow the slider to slide freely in the slide groove, so that the second rotating rod is separated from the fixed connection with the push rod. The rotation of the wrench and the first rotating rod cannot drive the second rotating rod to rotate, and thus cannot control the rotation of the stopper, thus achieving the locking operation of the ratchet by the stopper; S3. Unlocking. When the single lock anti-disconnection is closed, the first rotating rod can be driven to rotate by driving the motor, the electric drive assembly and the manual rotating wrench. The lower end of the first rotating rod pushes the wrench to rotate, and then pushes the side top plate to rotate the guide block, and the hook moves away from the ratchet to disengage the ratchet. At the same time, the upper end of the first rotating rod pushes the push rod to rotate the second rotating rod, and then moves the stop block away from the ratchet to disengage the ratchet. The hook and the stop block are disengaged at the same time, the ratchet rotates, and the locking ring is unlocked.

[0011] Compared with the known prior art, the technical solution provided by this application has the following beneficial effects: 1. The present application sets an anti-tripping component, sets a stopper on the outside of the ratchet, and uses the stopper to cooperate with the hook to double-lock the ratchet, which effectively reduces the possibility that the ratchet rotates and the lock ring is difficult to lock after the hook is accidentally tripped, effectively improves the stability of the trunk lid switch, and sets a push rod with a slide groove. By switching the connection relationship between the slider and the slide groove, the stopper is independent of the transmission mechanism, so that the ratchet cannot be unlocked by any means in the mechanism, and reduces the possibility that the wrench is accidentally touched when the hook is in a tripped state, causing the ratchet to rotate and the lock buckle to disengage, further improving the locking stability of the locking mechanism and ensuring the use effect of the switch; 2. The present application sets a first limit block, sets a first limit block and a second limit block with a reset torsion spring inside the slide groove, and divides the slide groove on the push rod into two parts by using the first limit block and the second limit block, thereby reducing the possibility of the slider entering a locked state when it is in a sliding state in the slide groove, and at the same time reducing the possibility of the slider entering a sliding state when it is engaged with the slide groove, thereby improving the working stability of the push rod and further improving the use effect of the anti-tripping component.

DETAILED DESCRIPTION

[0014] In order to better understand the above technical solution, Figure 1-10 And specific implementation methods are used to describe the above technical solutions in detail.

[0015] refer to Figures 1 to 3 The present application discloses an anti-tripping passenger car trunk lid switch, comprising a switch housing 1, a fixed plate, a locking mechanism 3, an electric drive assembly 4, an anti-tripping assembly 5 and a locking ring 6. The fixed plate is fixedly mounted on the outer side wall of the switch housing 1, the locking mechanism 3 is mounted on the fixed plate 2, the electric drive assembly 4 is fixedly mounted on a side surface of the fixed plate 2 away from the locking mechanism 3, and the locking ring 6 is mounted on one end of the switch housing 1 away from the fixed plate 2.

[0016] The fixing plate 2 is used to fix the locking mechanism 3, the electric drive assembly 4 and the anti-tripping assembly 5. The locking mechanism 3 is used in conjunction with the lock ring 6 to lock the lock ring 6. The anti-tripping hook assembly is used in conjunction with the locking mechanism 3 to lock the locking mechanism 3 for a second time, thereby achieving double locking of the lock ring 6 and reducing the possibility of accidental tripping and unlocking of the lock ring 6.

[0017] refer to Figures 2 to 4The locking mechanism 3 includes a ratchet 31, a pawl assembly 32, a pawl torsion spring 33, a first tension spring 34 and a wrench 35. The pawl assembly 32 includes a guide block 321, a hook pawl 322, an extension rod 323 and a side top plate 324. The ratchet 31 is rotatably mounted inside the switch housing 1, and the ratchet 31 is rotatably connected to the switch housing 1 through a torsion spring. The pawl assembly 32 is mounted inside the switch housing 1 and close to the ratchet 31. The pawl assembly 32 includes a guide block 321, a hook pawl 322, an extension rod 323 and a side top plate 324. The guide block 321 is rotatably mounted inside the switch housing 1 and close to the ratchet 31, the hook pawl 322 is fixedly mounted on the outside of the guide block 321 and close to the ratchet 31, and the hook pawl 322 can be engaged with the ratchet 31. The extension rod 323 is fixedly mounted on one end of the guide block 321, and the side top plate 324 is fixedly mounted on one end of the extension rod 323 away from the guide block 321. The ratchet torsion spring 33 is installed inside the switch housing 1 and close to the guide block 321, and the ratchet torsion spring 33 is used to reset the ratchet assembly 32. The first tension spring 34 is fixedly installed on a side surface of the fixed plate 2. The wrench 35 is rotatably installed on the fixed plate 2 and close to the side top plate 324. One end of the first tension spring 34 is fixedly connected to the fixed plate 2, and the other end of the first tension spring 34 is fixedly connected to the lower end of the wrench 35. The side top plate 324 is located within the range of motion of the wrench 35, and the rotation of the wrench 35 can push the side top plate 324 to move, thereby controlling the rotation of the guide block 321 through the extension rod 323.

[0018] When locking is required, the notch of the ratchet 31 that can engage with the lock ring 6 faces the outside of the switch housing 1, and the lock ring 6 can be embedded into the inside of the switch housing 1 from the outside of the switch housing 1. When the lock ring 6 moves toward the inside of the switch housing 1, the lock ring 6 abuts against the surface of the ratchet 31, and the lock ring 6 pushes the ratchet 31 to rotate. During the rotation process, the ratchet 31 abuts against the guide block 321. The outer wall of the ratchet 31 pushes the guide block 321, so that the guide block 321 drives the hook 322 to rotate, so that the ratchet 31 can pass over the hook 322. Under the action of the ratchet torsion spring 33, the guide block 321 and the hook 322 can return to their original positions, and the hook 322 can engage with the slot on the ratchet after rotation. After the hook 322 engages with the ratchet 31, the lock ring 6 is fixed inside the ratchet 31, completing the locking of the switch; When unlocking is needed, the electric drive component 4 is started and the electric telescopic rod of the electric drive component 4 is used to push the side top plate 324, or the wrench 35 on the fixed plate 2 is pulled and the side top plate 324 is pushed by the wrench 35 to make the side top plate 324 move away from the fixed plate 2. During the movement of the side top plate 324, the guide block 321 rotates inside the switch housing 1, and the hook pawl 322 gradually moves away from the ratchet 31, and the hook pawl 322 disengages from the engagement with the ratchet 31. When the ratchet 31 is disengaged, the ratchet 31 rotates under the action of the torsion spring and pushes the locking ring 6 outward, so that the locking ring 6 is disengaged from the engagement connection with the ratchet 31, thereby completing the unlocking of the switch, and then the first tension spring 34 pulls the wrench 35 back to its original position.

[0019] refer to Figures 5 to 10The anti-trip assembly 5 includes a traction rod 51, a first rotating rod 52, a push rod 53, a pull rod 531, a first limit block 533, a second limit block 534, a reset torsion spring 535, a second rotating rod 54, a slider 541, a stop block 55, a second tension spring 56 and a driving motor 57. The traction rod 51 is mounted at the lower end of the wrench 35, and the traction rod 51 is rotatably connected to the wrench 35. The first rotating rod 52 is rotatably mounted at the end of the traction rod 51 away from the wrench 35, and the first rotating rod 52 is rotatably connected to the traction rod 51. The first rotating rod 52 is rotatably mounted on the fixed plate 2, and a limit slot 521 is provided on the surface of the first rotating rod 52. The driving motor 57 is mounted inside the switch housing 1 and close to the limit slot 521, and the output end of the driving motor 57 is plugged into the inside of the limit slot 521, and the output end of the driving motor 57 passes through the limit slot 521 and is rotatably connected to the fixed plate 2. The output end of the driving motor 57 rotates to drive the first rotating rod 52 to rotate. The push rod 53 is rotatably mounted on the upper end of the first rotating rod 52, and the push rod 53 is rotatably connected to the first rotating rod 52. A U-shaped slide groove 532 is provided on the surface of the push rod 53. The pull rod 531 is fixedly mounted on the upper end of the push rod 53 and away from the first rotating rod 52. The first limit block 533 is rotatably mounted inside the push rod 53 and close to the slide groove 532. A return torsion spring 535 is installed between the first limit block 533 and the push rod 53 to assist the rotation of the first limit block 533 after rotation. The second limit block 534 is rotatably mounted inside the push rod 53 and close to the first limit block 533. Another return torsion spring 535 is installed between the second limit block 534 and the push rod 53 to assist the rotation of the second limit block 534 after rotation. The second rotating rod 54 is mounted on the fixed plate 2 and close to the push rod 53. The slider 541 is fixedly mounted on the upper end of the second rotating rod 54 and close to the push rod 53. The slider 541 is inserted into the slide groove 532 on the push rod 53. The slider 541 moves in the slide groove 532. The lower end of the second rotating rod 54 is inserted into the fixed plate 2, and the lower end of the second rotating rod 54 is rotatably connected to the fixed plate 2. The stopper 55 is fixedly mounted on one end of the second rotating rod 54 that passes through the fixed plate 2 and close to the ratchet 31. The second tension spring 56 is fixedly mounted on the fixed plate 2 and close to the stopper 55. One end of the second tension spring 56 is fixedly connected to the fixed plate 2, and the other end of the second tension spring 56 is fixedly connected to the stopper 55.

[0020] During operation, when the ratchet 31 rotates, it pushes the hook 322 on the guide block 321 and the stop block 55 at the lower end of the second rotating rod 54 at the same time. When the slot of the ratchet 31 passes over the hook 322 and the stop block 55, the hook 322 and the stop block 55 return to their positions at the same time, and the ratchet 31 is clamped and fixed at different positions. When the ratchet torsion spring 33 of the hook 322 drives the hook 322 to rotate and causes the hook 322 to be accidentally disengaged, the stop block 55 abuts against the outer wall of the ratchet 31 to prevent the ratchet 31 from rotating. Similarly, when the second tension spring 56 of the stop block 55 is disconnected and causes the stop block 55 to be accidentally disengaged, the hook 322 abuts against the outer wall of the ratchet 31 to prevent the ratchet 31 from rotating. Double locking of the switch is achieved.

[0021] After being locked, the anti-tripping assembly 5 has two working states: double locking and single locking anti-tripping.

[0022] Double locking state: the slider 541 at the upper end of the second rotating rod 54 is located inside the slide groove 532 of the push rod 53 and abuts against the outer side walls of the first limit block 533 and the second limit block 534 , and the slider 541 is fixed inside the push rod 53 .

[0023] In this state, the hook 322 and the stopper 55 simultaneously engage and fix the ratchet 31, thereby improving the locking stability of the ratchet 31. The rotation of the side top plate 324 and the hook 322 does not interfere with the stopper 55, and the rotation of the side top plate 324 and the hook 322 cannot drive the stopper 55 and the second rotating rod 54 to rotate. Therefore, the accidental release of the hook 322 cannot directly unlock the switch. When unlocking is required, the wrench 35 is rotated or the electric drive assembly 4 is turned on, so that the electric drive assembly 4 pushes the wrench 35 to rotate, and the rotation of the wrench 35 drives the traction rod 51 to move. After the traction rod 51 is displaced, the traction rod 51 drives the lower end of the first rotating rod 52 to rotate, thereby rotating the first rotating rod 52, and rotating the upper end of the first rotating rod 52 toward the direction of the second rotating rod 54. Since the slider 541 is fixedly connected to the push rod 53 in this state, when the first rotating rod 52 rotates, the push rod 53 will push the second rotating rod 54 to rotate, thereby rotating the stop block 55 away from the ratchet 31, so that the stop block 55 is separated from the contact with the ratchet 31. At the same time, the rotation of the wrench 35 will push the side top plate 324 to displace, thereby driving the guide block 321 to rotate, and the hook pawl 322 moves away from the ratchet 31, so that the hook pawl 322 is separated from the contact with the ratchet 31, and the double lock on the ratchet 31 is unlocked, and the ratchet 31 can rotate freely. The ratchet 31 rotates back to its original position under the action of the torsion spring, and the lock ring 6 is released. In this state, the rotation of the guide block 321 and the hook 322 does not interfere with the stop block 55. Simply rotating the guide block 321 and the hook 322 cannot release the locking state of the anti-tripping assembly 5 on the ratchet 31, thereby achieving the anti-tripping effect of the anti-tripping assembly 5. However, when the wrench 35 is driven manually or electrically, the stop block 55 can release the engagement connection with the ratchet 31 at the same time as the hook 322, thereby completing the unlocking of the switch. When the electric drive assembly 4 fails and it is difficult to push the wrench 35, the drive motor 57 can drive the first rotating rod 52 to rotate, thereby driving the wrench 35 and the second rotating rod 54 to rotate, thereby completing the unlocking.

[0024] Single lock anti-tripping state: the slider 541 at the upper end of the second rotating rod 54 slides freely in the sliding groove 532 of the push rod 53.

[0025] In this state, the stopper 55 abuts against the outer wall of the ratchet 31 under the action of the second tension spring 56. When the first rotating rod 52 rotates, the displacement of the push rod 53 cannot push the slider 541 to move, and further cannot drive the second rotating rod 54 to rotate. Therefore, the rotation of the first rotating rod 52 cannot drive the stopper 55 to rotate. Therefore, the rotation of the wrench 35 cannot drive the second rotating rod 54 to rotate, and the driving motor 57 cannot drive the second rotating rod 54 to rotate through the rotation of the first rotating rod 52. The stopper 55 will always abut against the outer wall of the ratchet 31. When and only when the slider 541 is again engaged in the slide groove 532 on the push rod 53, the rotation of the first rotating rod 52 can drive the second rotating rod 54 to rotate, and then the stopper 55 can rotate to unlock the ratchet 31.

[0026] A method for using a passenger car trunk lid switch based on anti-tripping comprises the following steps: S1. Locking, so that the lock ring 6 and the ratchet 31 are close to each other, the lock ring 6 pushes the ratchet 31 to rotate, and the ratchet 31 pushes the guide block 321 and the stop block 55 to rotate. When the ratchet 31 can be engaged with the hook pawl 322 and the stop block 55, the guide block 321 rotates under the action of the ratchet pawl torsion spring 33, and the stop block 55 rotates under the action of the second tension spring 56. The hook pawl 322 and the stop block 55 are engaged with the slot on the ratchet 31 at the same time, and the ratchet 31 is doubly locked; S2. After the single lock anti-dropping buckle is turned on and the ratchet 31 is engaged with the stopper 55, the pull rod 531 is pressed down so that the slider 541 can slide freely in the slide groove 532, so that the second rotating rod 54 is separated from the fixed connection with the push rod 53. The rotation of the wrench 35 and the first rotating rod 52 cannot drive the second rotating rod 54 to rotate, and thus cannot control the rotation of the stopper 55, so that the stopper 55 can lock the ratchet 31; S3. Unlocking. When the single lock anti-tripping is closed, the first rotating rod 52 can be driven to rotate by driving the motor 57, the electric drive assembly 4 and the manually rotating wrench 35. The lower end of the first rotating rod 52 pushes the wrench 35 to rotate, and then pushes the side top plate 324 to rotate the guide block 321, and the hook pawl 322 moves away from the ratchet 31 to disengage the ratchet 31. At the same time, the upper end of the first rotating rod 52 pushes the push rod 53 to rotate the second rotating rod 54, and then moves the stop block 55 away from the ratchet 31 to disengage the ratchet 31. The hook pawl 322 and the stop block 55 are disengaged at the same time, the ratchet 31 rotates, and the locking ring 6 is unlocked.

[0027] The working principle of the embodiment of this application: When locking, the lock ring 6 and the ratchet 31 move closer to each other, and the lock ring 6 pushes the ratchet 31 to rotate. The rotation of the ratchet 31 pushes the guide block 321, the hook 322 and the stop block 55 to rotate. When the ratchet 31 passes over the hook 322, the hook 322 rotates and engages with the slot on the ratchet 31 under the action of the ratchet torsion spring 33. Under the action of the second tension spring 56, the stop block 55 rotates and engages with another slot on the ratchet 31, locking the ratchet 31 inside the switch housing 1, and locking the lock ring 6 with the ratchet 31. After the lock ring 6 is locked, the pull rod 531 is pressed down to move the slider 541 to the upper end of the slide groove 532, and the slider 541 can slide freely in the slide groove 532. In this state, the ratchet 31 is locked by the block 55, and the rotation of the wrench 35 and the first rotating rod 52 cannot drive the second rotating rod 54 to rotate, and then the second rotating rod 54 cannot be used to drive the block 55 to rotate. The accidental disengagement of the hook 322 and the accidental rotation of the wrench 35 and the first rotating rod 52 cannot unlock the ratchet 31, and the locking ring 6 is completely locked.

[0028] When the ratchet 31 needs to be unlocked, the pull rod 531 is pulled upward so that the slider 541 is again engaged in the slide groove 532 for fixing. In this state, the electric drive assembly 4, the drive motor 57 and the wrench 35 can drive the first rotating rod 52 to rotate, thereby controlling the rotation of the stop block 55 to unlock the ratchet 31. The rotation of the first rotating rod 52 can drive the second rotating rod 54 to rotate, thereby rotating the stop block 55, and the ratchet 31 can be disengaged from the engagement with the stop block 55. Then, by rotating the wrench 35, the hook 322 and the stop block 55 are driven to rotate, thereby unlocking the ratchet 31, and completing the unlocking operation of the lock ring 6.

[0029] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.

A second limit block (534) is provided on the inner side wall of the push rod (53) and close to the first limit block (533). The first limit block (533) is rotatably connected to the push rod (53), and a return torsion spring (535) is provided between the first limit block (533) and the push rod (53). The second limit block (534) is also rotatably connected to the push rod (53), and another return torsion spring (535) is provided between the second limit block (534) and the push rod (53).

6. A method for using the anti-tripping passenger car trunk lid switch according to claim 5, characterized in that: The following steps are included: S1. Locking, so that the lock ring (6) and the ratchet (31) are close to each other, the lock ring (6) drives the ratchet (31) to rotate, and the ratchet (31) drives the guide block (321) and the stop block (55) to rotate. When the ratchet (31) can engage with the hook (322) and the stop block (55), the guide block (321) rotates under the action of the ratchet torsion spring (33), and the stop block (55) rotates under the action of the second tension spring (56). The hook (322) and the stop block (55) are simultaneously engaged with the slot on the ratchet (31), and the ratchet (31) is doubly locked; S2. After the single lock anti-dropping buckle is opened and the ratchet (31) is engaged with the stopper (55), the pull rod (531) is pressed downward to allow the slider (541) to slide freely in the slide groove (532), so that the second rotating rod (54) is separated from the fixed connection with the push rod (53). The rotation of the wrench (35) and the first rotating rod (52) cannot drive the second rotating rod (54) to rotate, and thus cannot control the rotation of the stopper (55), thereby achieving the locking operation of the stopper (55) on the ratchet (31); S3. Unlocking. When the single lock anti-tripping is closed, the first rotating rod (52) can be driven to rotate by driving the motor (57), the electric drive assembly (4) and the manually rotating spanner (35). The lower end of the first rotating rod (52) pushes the spanner (35) to rotate, thereby pushing the side top plate (324), causing the guide block (321) to rotate, and the hook (322) to move in a direction away from the ratchet (31), so that the ratchet (31) is disengaged. At the same time, the upper end of the first rotating rod (52) pushes the push rod (53), causing the second rotating rod (54) to rotate, thereby causing the stop block (55) to move in a direction away from the ratchet (31), so that the ratchet (31) is disengaged, the hook (322) and the stop block (55) are disengaged at the same time, the ratchet (31) rotates, and the lock ring (6) is unlocked.
