Figure 4 As shown, the upper protrusion 51 at the end of the pawl link 5 is blocked by the outer lower contour of the lock hook 2 , and at the same time, the second pawl 4 cooperates with the protrusion 23 on the lock hook 2 .

[0034] In a specific embodiment of the present invention, a limiting groove 52 is formed on the pawl link 5 to cooperate with the second pawl 4. In the semi-locked state, one end of the second pawl 4 is engaged in the limiting groove 52. Figure 6 As shown, the limiting groove 52 can just accommodate one end of the second pawl 4.

[0035] In a specific embodiment of the utility model, the automobile hood lock with electric opening, electric suction and manual release functions of the utility model also includes a suction assembly 6, the suction assembly 6 includes a suction execution bracket 61, a suction execution rod 62, a suction active rod 63 and a suction driven rod 64, the suction execution bracket 61 is rotatably assembled on the lock body, the suction execution rod 62 is rotatably assembled on the lock body, and is coaxial with the suction execution bracket 61, and the suction active rod 63 is hinged on the suction execution bracket 61. The suction driven rod 64 is hinged on the locking hook 2 and is subjected to the counterclockwise torsion spring force. After the suction executing rod 62 is pulled, the suction executing rod 62 and the suction executing bracket 61 rotate clockwise, and the suction active rod 63 follows the suction executing rod 62 and the suction executing bracket 61 to rotate clockwise. At the same time, it rotates counterclockwise around its own fixed axis under the action of the torsion spring force and fits with the suction driven rod 64 and pushes the suction driven rod 64 to rotate the locking hook 2 counterclockwise to the fully locked state.

[0036] Specifically, the zipper is installed on the suction actuator rod 62. When the zipper is pulled, the suction actuator rod 62 and the suction actuator bracket 61 rotate clockwise together, and the suction active rod 63 follows the suction actuator rod 62 bracket to rotate clockwise, and at the same time, it rotates counterclockwise around its own fixed axis under the action of the torsion spring force and fits with the suction driven rod 64. The zipper is continuously pulled, and the suction active rod 63 pushes the suction driven rod 64 and the lock hook 2 to rotate counterclockwise to the fully locked position. After the zipper is released, the suction actuator rod 62 is reset under the action of the torsion spring force.

[0037] In a specific embodiment of the utility model, the automobile hood lock with electric opening, electric suction and manual release functions of the utility model also includes a suction interruption component 7, the suction interruption component 7 includes a manual release rod 71 and a suction interruption rod 72, the manual release rod 71 is rotatably assembled on the lock body, one end of the manual release rod 71 drives the suction interruption rod 72 through a cable, and the suction interruption rod 72 is rotatably assembled on the lock body. When the manual release rod 71 is manually controlled to rotate counterclockwise, the first pawl 3 is pushed to rotate clockwise. When the manual release rod 71 rotates counterclockwise, the suction interruption rod 72 is pulled to rotate clockwise, and the suction active rod 63 is pushed away through the outer contour of the suction interruption rod 72 to ensure that the suction active rod 63 will not block the clockwise rotation path of the lock hook 2.

[0038] The automobile hood lock with electric opening, electric closing and manual release functions of the utility model has a manual release rod 71 and a pawl that are no longer coaxial, thereby reducing the overall thickness and making the design structure more compact, and the closing and breaking rod 72 is thicker and stronger.

[0039] Furthermore, a one-way limiting feature 711 is formed on the manual release lever 71 to push the first pawl 3 to rotate clockwise when the manual release lever 71 rotates counterclockwise.

[0040] Specifically, by pulling the zipper, the manual release lever 71 rotates counterclockwise, and the unidirectional limit block pushes the first pawl 3 to rotate clockwise, and the state from fully locked, half locked to fully opened can be completed by pulling twice. When the manual release lever 71 rotates counterclockwise, the zipper of the suction breaking lever 72 pulls the suction breaking lever 72 to rotate clockwise, and presses the suction active lever 63 downward through the outer contour to ensure that it will not block the clockwise rotation path of the lock hook 2.

[0041] It should be noted that the torsion spring force exerted on each component of the utility model is realized by the torsion spring arranged on the component.

[0042] In summary, the automobile hood lock with electric opening, electric closing and manual release functions of the utility model can realize electric opening and electric closing functions, and the manual release function can realize unlocking under all working conditions; the overall structure is compact and the volume is small; there is only one step from full lock to half lock, the noise of opening and closing is small, and the time domain of the noise is narrower; the actuator and the lock body are separated, and the layout of the whole vehicle is more flexible; one lock hook 2 realizes the safe locking position and the fully open locking position, and there is no safety lock hook 2, the lock body can be arranged in the trim panel, and the hood is more beautiful after opening.

[0043] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention.
