Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0031] Example: Figures 1-4 As shown, an actuator for unlocking a car door upon collision includes a housing 1. The housing 1 has a first mounting cavity 101 and a second mounting cavity 102. The first mounting cavity 101 and the second mounting cavity 102 are vertically distributed and are connected in a detachable manner (such as by snap-fit).

[0032] An unlocking push rod 2 is installed inside the first mounting cavity 101. The unlocking push rod 2 is movably inserted into the first mounting cavity 101. One end of the unlocking push rod 2 is connected to a first elastic element 3. One end of the first elastic element 3 abuts against the inner wall of the first elastic element 3, and the other end abuts against the end of the unlocking push rod 2. The other end of the unlocking push rod 2 can extend out of the first mounting cavity 101 to the outside. The first elastic element 3 is used to push the unlocking push rod 2 out of the first mounting cavity 101. The first elastic element 3 can be a spring.

[0033] The swing lever 4 is installed in the second installation cavity 102 and is suspended in the second installation cavity 102. The lower end of the swing lever 4 can swing in multiple directions, and the outer side of the swing lever 4 is provided with multiple elastic supporting members 6. In this embodiment, the upper end of the swing lever 4 is provided with a movable connecting member 5, the movable connecting member 5 is installed in the second installation cavity 102 through a first rotating shaft 501, the upper end of the swing lever 4 is installed on the movable connecting member 5 through a second rotating shaft 502, the axis of the first rotating shaft 501 is perpendicular to the axis of the second rotating shaft 502, so that the swing lever 4 swings in four directions of front, back, left and right. The four elastic supporting members 6 support the swing lever 4 in the four directions of front, back, left and right. The elastic supporting member 6 is a spring, one end of the spring is fixed on the inner wall of the second installation cavity 102, and the other end of the spring abuts against the swing lever 4.

[0034] A locking mechanism is arranged between the swing lever 4 and the unlocking push rod 2, and the unlocking push rod 2 is locked in the first installation cavity 101 in the vertical state of the swing lever 4 through the locking mechanism.

[0035] The locking mechanism includes a swing arm 7, one end of the swing arm 7 is hinged in the first installation cavity 101, the other end of the swing arm 7 abuts against the unlocking push rod 2 and is clamped with the unlocking push rod 2, and the lower end of the swing lever 4 is clamped with the swing arm 7.

[0036] The end of the swing arm 7 is provided with a protruding clamping block 701, and the unlocking push rod 2 is provided with a clamping groove 201 matched with the clamping block 701. The clamping block 701 is an arc-shaped block, and the clamping groove 201 is a matching arc-shaped groove.

[0037] A second elastic member 8 is arranged in the first installation cavity 101, the second elastic member 8 is a spring, one end of the spring is fixed on the inner wall of the first installation cavity 101, and the other end of the spring abuts against the swing arm 7. The second elastic member 8 drives the swing arm 7 to abut against the unlocking push rod 2, and the elastic force of the first elastic member 3 is greater than the elastic force of the second elastic member 8. When the clamping block 701 is clamped into the clamping groove 201, the first elastic member 3 can push the unlocking push rod 2 to move axially, so that the groove wall of the clamping groove 201 extrudes the clamping block 701, the swing arm 7 swings upward, and the clamping block 701 slides out of the clamping groove 201.

[0038] As shown in FIG. 1, Figure 4 The middle part of the swing arm 7 is provided with a positioning column 702, the positioning column 702 extends upward below the swing lever 4, the upper end of the positioning column 702 is provided with a positioning groove 703, and the lower end of the swing lever 4 is provided with a positioning rod 401 inserted into the positioning groove 703. The positioning groove 703 is shallow and arc-shaped.

[0039] A sliding groove 103 communicating with the first installation cavity 101 is arranged on the side wall of the shell 1, and a push rod 202 is arranged in the sliding groove 103. The push rod 202 is fixedly connected to the unlocking push rod 2, so as to facilitate the movement of the unlocking push rod 2 to reset.

[0040] As shown in FIG. 1, Figure 6As shown, the actuator is used in cooperation with the lock, the actuator is installed on one side of the lock 9, the unlocking push rod 2 is used to push the swing arm 901 of the lock 9 to swing, so that the lock 9 is unlocked.

[0041] As shown in the normal state, the positioning rod 401 at the lower end of the swing rod 4 is inserted into the positioning groove 703, and the clamping block 701 is clamped into the clamping groove 201, so that the swing arm 7 cannot swing upward, and the first elastic member 3 cannot push the unlocking push rod 2 to move axially. Figure 3

[0042] As shown in the normal state, the positioning rod 401 at the lower end of the swing rod 4 is inserted into the positioning groove 703, and the clamping block 701 is clamped into the clamping groove 201, so that the swing arm 7 cannot swing upward, and the first elastic member 3 cannot push the unlocking push rod 2 to move axially. Figure 5 As shown, after the collision, the swing rod 4 swings under the action of inertia, the lower end of the swing rod 4 overcomes the elastic force of the elastic support member 6 in a certain direction, and the lower end of the positioning rod 401 extrudes the groove wall of the positioning groove 703 to make the swing arm 7 swing slightly downward, so that the positioning rod 401 slides out of the positioning groove 703; because the swing arm 7 loses the restriction of the swing rod 4, the clamping effect of the clamping block 701 and the clamping groove 201 cannot restrict the movement of the unlocking push rod 2, so that the first elastic member 3 pushes the unlocking push rod 2 to move, so that the end of the unlocking push rod 2 extends, the unlocking push rod 2 pushes the swing arm 901 of the lock 9 to swing, so that the lock 9 is unlocked, so that the door can be opened.​
