Description

TECHNICAL FIELD

[0001] The application relates to the technical field of passenger car switch devices, in particular to a passenger car trunk lid switch capable of preventing tripping and a use method thereof. BACKGROUND

[0002] A passenger car is an automobile for people to ride, and is mainly used for carrying passengers and their luggage or temporary articles in terms of design and technical characteristics. According to the national standard, passenger cars can be divided into sedans, multipurpose vehicles, sport utility vehicles, special passenger cars and cross-type passenger cars. Special passenger cars generally refer to ambulances, funeral cars and other passenger cars with professional purposes.

[0003] A passenger car trunk lid switch, namely an automobile tail door lock, is a device installed on a trunk lid and capable of locking the trunk of the automobile and opening the trunk through the internal structure of the device. The device is a very important vehicle body accessory and has a safety protection function. The device needs to ensure reliable locking of the door during normal use and prevent accidental opening, and needs to ensure smooth opening of the door when the door needs to be opened.

[0004] In the prior art, the tail door lock is connected to the lock catch through the clamping connection of a single ratchet and a hook, and the spring is used to energize the hook and the ratchet. When the hook and the ratchet are disengaged, the ratchet releases the lock catch, and the unlocking of the tail door lock is completed. However, the hook of this mode is prone to tripping, which makes it difficult for the ratchet to be clamped with the hook, and thus the lock catch is difficult to be locked, resulting in that the trunk lid cannot be smoothly closed, and even the trunk lid may be accidentally opened during driving. SUMMARY

[0035] Reference Figures 5 to 10The anti-dropping-off assembly 5 comprises a traction rod 51, a first rotating rod 52, a push rod 53, a pull rod 531, a first limiting block 533, a second limiting block 534, a reset torsional spring 535, a second rotating rod 54, a sliding block 541, an abutting block 55, a second pull spring 56 and a driving motor 57. The traction rod 51 is installed at the lower end of the wrench 35, and the traction rod 51 is rotationally connected with the wrench 35. The first rotating rod 52 is rotationally installed at the end of the traction rod 51 away from the wrench 35, and the first rotating rod 52 is rotationally connected with the traction rod 51. The first rotating rod 52 is rotationally installed on the fixed plate 2, and a limiting slot 521 is formed in the surface of the first rotating rod 52. The driving motor 57 is installed inside the switch housing 1 and close to the limiting slot 521, the output end of the driving motor 57 is inserted into the inside of the limiting slot 521, and the output end of the driving motor 57 is rotationally connected with the fixed plate 2 after penetrating through the limiting slot 521. The output end of the driving motor 57 can drive the first rotating rod 52 to rotate. The push rod 53 is rotationally installed at the upper end of the first rotating rod 52, and the push rod 53 is rotationally connected with the first rotating rod 52. A U-shaped sliding groove 532 is formed in the surface of the push rod 53. The pull rod 531 is fixedly installed at the upper end of the push rod 53 and away from the first rotating rod 52. The first limiting block 533 is rotationally installed inside the push rod 53 and close to the sliding groove 532, and the reset torsional spring 535 is installed between the first limiting block 533 and the push rod 53 to assist the rotation of the first limiting block 533. The second limiting block 534 is rotationally installed inside the push rod 53 and close to the first limiting block 533, and another reset torsional spring 535 is installed between the second limiting block 534 and the push rod 53 to assist the rotation of the second limiting block 534. The second rotating rod 54 is installed on the fixed plate 2 and close to the push rod 53, the sliding block 541 is fixedly installed at the upper end of the second rotating rod 54 and close to the push rod 53, and the sliding block 541 is inserted into the sliding groove 532 on the push rod 53 and moves in the sliding groove 532. The lower end of the second rotating rod 54 is inserted into the fixed plate 2 and rotationally connected with the fixed plate 2, and the abutting block 55 is fixedly installed at the end of the second rotating rod 54 penetrating through the fixed plate 2 and close to the ratchet wheel 31. The second pull spring 56 is fixedly installed on the fixed plate 2 and close to the abutting block 55, and one end of the second pull spring 56 is fixedly connected with the fixed plate 2, and the other end of the second pull spring 56 is fixedly connected with the abutting block 55.

[0036] In the work, the ratchet 31 rotates, while pushing the pawl 322 on the guide block 321 and the block 55 at the lower end of the second rotating rod 54, when the ratchet 31 passes the pawl 322 and the block 55, the pawl 322 and the block 55 are reset at the same time, and the ratchet 31 is clamped and fixed at different positions. When the pawl 322 is rotated by the pawl torsion spring 33 and the pawl 322 is accidentally tripped, the block 55 abuts against the outer side wall of the ratchet 31, preventing the rotation of the ratchet 31. Similarly, when the second tension spring 56 of the block 55 is disconnected and the block 55 is accidentally tripped, the pawl 322 abuts against the outer side wall of the ratchet 31, preventing the rotation of the ratchet 31. The double locking of the switch is realized.

[0037] The anti-tripping assembly 5 has two working states of double locking and single locking after being locked.

[0038] Double locking state: the sliding block 541 at the upper end of the second rotating rod 54 is located inside the sliding groove 532 of the push rod 53, and abuts against the outer side wall of the first limiting block 533 and the second limiting block 534, and the sliding block 541 is fixed inside the push rod 53.

[0039] In this state, the hook 322 and the block 55 are simultaneously clamped and fixed to the ratchet 31, improving the stability of the ratchet 31 locking. The rotation of the side top plate 324 and the hook 322 does not interfere with the block 55, and the rotation of the side top plate 324 and the hook 322 cannot drive the block 55 and the second rotating rod 54 to rotate, so that the accidental release of the hook 322 cannot directly unlock the switch. When unlocking is needed, the electric drive assembly 4 is started to drive the wrench 35 to rotate, and the rotation of the wrench 35 drives the displacement of the traction rod 51. After the displacement of the traction rod 51, the lower end of the first rotating rod 52 is driven to rotate by the traction rod 51, and then the first rotating rod 52 is rotated, so that the upper end of the first rotating rod 52 is rotated towards 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 drives the second rotating rod 54 to rotate, and then the block 55 is rotated away from the ratchet 31, so that the block 55 is separated from the ratchet 31. At the same time, the rotation of the wrench 35 drives the displacement of the side top plate 324, and then drives the guide block 321 to rotate, so that the hook 322 moves away from the ratchet 31, and the hook 322 is separated from the ratchet 31. The double lock of the ratchet 31 is unlocked, and the ratchet 31 can freely rotate. The ratchet 31 is returned to the original position under the action of the torsional 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 block 55, and the rotation of the guide block 321 and the hook 322 cannot release the locking state of the anti-dropping assembly 5 to the ratchet 31, thereby achieving the anti-dropping effect of the anti-dropping assembly 5. However, when the wrench 35 is manually or electrically driven, the block 55 can simultaneously release the clamping connection to the ratchet 31 with the hook 322, and the unlocking of the switch is completed. When the electric drive assembly 4 fails to drive the wrench 35, the driving motor 57 can drive the first rotating rod 52 to rotate, and then drive the wrench 35 and the second rotating rod 54 to rotate, thereby completing the unlocking.

[0040] Single-lock anti-dropping state: the slider 541 on the upper end of the second rotating rod 54 freely slides in the sliding groove 532 of the push rod 53.

[0041] In this state, the block 55 is in abutment with the outer side 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 drive the slider 541 to move, and then the second rotating rod 54 cannot be driven to rotate, so that the rotation of the first rotating rod 52 cannot drive the block 55 to rotate. Therefore, the rotation of the wrench 35 cannot drive the second rotating rod 54 to rotate, and the driving motor 57 also cannot drive the second rotating rod 54 to rotate through the rotation of the first rotating rod 52. The block 55 will always be in abutment with the outer side wall of the ratchet 31. Only when the slider 541 is again clamped in the sliding groove 532 on the push rod 53, the rotation of the first rotating rod 52 can drive the rotation of the second rotating rod 54, and then the block 55 is rotated to unlock the ratchet 31.

Locking, the lock ring 6 and the ratchet wheel 31 are close to each other, the lock ring 6 pushes the ratchet wheel 31 to rotate, the ratchet wheel 31 pushes the guide block 321 and the block 55 to rotate, when the ratchet wheel 31 can be engaged with the hook 322 and the block 55, the guide block 321 rotates under the action of the ratchet pawl torsional spring 33, the block 55 rotates under the action of the second tension spring 56, the hook 322 and the block 55 are engaged with the clamping groove on the ratchet wheel 31 at the same time, and the ratchet wheel 31 is double-locked;

[0045] S3. Unlocking, in the state of single-lock anti-tripping, the first rotating rod 52 can be driven to rotate through the driving motor 57, the electric drive assembly 4 and the manual rotation of the 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 rotates, the hook 322 moves away from the ratchet wheel 31, the upper end of the first rotating rod 52 pushes the push rod 53, the second rotating rod 54 rotates, and then the block 55 moves away from the ratchet wheel 31, the ratchet wheel 31 is tripped, the hook 322 and the block 55 are tripped at the same time, the ratchet wheel 31 rotates, and the lock ring 6 is unlocked.

After the lock ring 6 is locked, the pull rod 531 is pressed down, the sliding block 541 moves to the upper end of the sliding groove 532, and the sliding block 541 can slide freely in the sliding groove 532.
