[0017] A self-suction integrated lock, such as Figures 1-3 As shown, including the shell 1 and set in the shell 1 drive assembly 2, self-suction disc 3, connecting rod assembly 4, hook 5, pawl 6 and drive arm 7, hook 5 and pawl 6 are respectively rotatably connected with the shell 1, through the cooperation of hook 5 and pawl 6, realize the lock and unlock. Self-suction disc 3 is rotatably connected with the shell 1 through shaft 8, that is, self-suction disc 3 rotates around shaft 8. Self-suction disc 3 is connected with hook 5 through connecting rod assembly 4, and then drives hook 5 to move through connecting rod assembly 4. Drive arm 7 is installed on pawl 6 and extends to the front of self-suction disc 3, the front and back of self-suction disc 3 are respectively provided with first driving part 31 and second driving part 32, first driving part 31 provides power for drive arm 7, and second driving part 32 provides power for connecting rod assembly 4; drive assembly 2 provides rotating power for self-suction disc 3 to control the forward rotation or inversion of self-suction disc 3, rotates self-suction disc 3 to make first driving part 31 push drive arm 7 to drive pawl 6 to rotate, and then make the lock to be unlocked, or second driving part 32 pushes connecting rod assembly 4 to drive hook 5 to rotate from the unlocked state to the locked state, or the first driving part 31 and the second driving part 32 are in the default position; That is, first driving part 31 and second driving part 32 are not in contact with connecting rod assembly 4 and drive arm 7.
[0018] In an embodiment, as shown in Figures 1-3 Connecting rod assembly 4 includes first connecting rod 41, second connecting rod 42, third connecting rod 43, fourth connecting rod 44 and guide block 45, guide block 45 is fixed in the shell 1, third connecting rod 43 is slidably connected with guide block 45, two ends of first connecting rod 41 are respectively hinged with shaft 8 and one end of second connecting rod 42, the other end of second connecting rod 42 is hinged with third connecting rod 43, and two ends of fourth connecting rod 44 are respectively hinged with third connecting rod 43 and hook 5. In use, drive assembly 2 drives self-suction disc 3 to rotate, so that second driving part 32 approaches first connecting rod 41, because first connecting rod 41 is rotatably connected with shaft 8, second driving part 32 pushes first connecting rod 41 to rotate around shaft 8 after contacting with first connecting rod 41, the other end of first connecting rod 41 pushes second connecting rod 42 to make third connecting rod 43 move along the guide direction of guide block 45, and then fourth connecting rod 44 pushes hook 5 to rotate.
[0019] In an embodiment, as shown in Figures 1-3 Guide groove 451 is recessed on guide block 45, and guide part 431 is provided on third connecting rod 43. Among them, guide part 431 is a sheet-shaped structure extending from third connecting rod 43. At the same time, guide groove 451 plays a limiting role.
[0020] In an embodiment, as shown in Figures 1-3 Limiting part 452 is protruded on guide block 45. Limiting part 452 is used to block the movement range of second connecting rod 42, further protect the lock, and prevent the overdrive of connecting rod assembly 4.
[0021] In an embodiment, asFigures 1-3 As shown in the figure, the driving assembly 2 comprises a motor 21, a worm 22 and a main gear 23, the main gear 23 is coaxially provided with a first tooth set 231 and a second tooth set 232, the worm 22 is connected with the motor 21, the worm 22 is engaged with the first tooth set 231; the second tooth set 232 is engaged with the self-suction disc 3.
[0022] In an embodiment, as Figures 1-3 As shown in the figure, the shell 1 is provided with a through hole 11, the driving arm 7 is provided with a hand lever 71, the hand lever 71 is placed in the through hole 11 and protrudes from the through hole 11, so that the hand lever 71 can be driven outside the shell 1 to drive the pawl 6 to move.
[0023] The utility model discloses in using, as Figures 1-3 As shown in the figure, the use scene is set as a car tail door, and the self-suction disc 3 is in the default position; the tail door is closed, the lock catch on the car is placed in the ratchet hook 5, the worm 22 is driven to rotate by the motor 21 to drive the main gear 23 to rotate, and then drives the self-suction disc 3 to rotate, so that the second driving part 32 pushes the first connecting rod 41 to drive the mechanism 5 to rotate through the connecting rod assembly 4 and hooks the lock catch; at the same time, the torsional spring between the pawl 6 and the shell 1 makes it always close to the ratchet hook 5, and the ratchet hook 5 cannot be reversely rotated through the mutual cooperation and engagement of the pawl 6 and the ratchet hook 5, so that the lock is realized; the self-suction disc 3 is restored to the default position through the driving assembly 2. When unlocking through the driving assembly 2, the worm 22 is driven to rotate by the motor 21 to drive the main gear 23 to rotate, and then drives the self-suction disc 3 to rotate, so that the first driving part 31 moves to the driving arm 7, and the pawl 6 is driven to rotate by the driving arm 7 to move away from the ratchet hook 5, at this time, the ratchet hook 5 is not locked, the tail door is opened, the ratchet hook 5 is reversely rotated and separated from the lock catch, the unlocking is completed, and then the driving assembly 2 is reversely moved so that the self-suction disc 3 rotates to the default position.
[0024] The above is to realize the locking and unlocking of the lock through the driving assembly 2. When the self-suction disc 3 is in the default position, at this time, the ratchet hook 5 and the pawl 6 can be independently driven, the tail door is closed, the tail door is pressed, the ratchet hook 5 is driven to rotate through the lock catch on the car to realize the manual locking. The pawl 6 is driven to rotate through the lever 71, the ratchet hook 5 and the pawl 6 are disengaged, and the unlocking is realized. Further, the manual locking and unlocking are realized.
[0025] The above is only a preferred embodiment of the utility model, and is not used to limit the implementation range of the utility model; if the utility model is modified or replaced equivalently without departing from the spirit and range of the utility model, all should be covered in the protection range of the utility model claim.
