DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0022] First embodiment

[0023] Please refer to Figure 1and Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of a self-priming actuator provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the structure inside the shell is shown. The self-priming actuator comprises:

[0024] A housing 1, wherein a plurality of mounting posts 2 are disposed inside the housing 1, an interface 3 is disposed inside the housing 1, a connection module 11 is disposed inside the housing 1, and a micro switch 12 is disposed inside the housing 1;

[0025] The motor 5 is arranged inside the housing 1, and the output end of the motor 5 is connected to a worm 6 through a coupling, the surface of the worm 6 is meshed with a worm wheel 61, the inside of the worm wheel 61 is fixedly connected with a rotating rod 62, the surface of the rotating rod 62 is fixedly connected with a first bevel gear 7, the surface of the first bevel gear 7 is meshed with a second bevel gear 8, the inside of the second bevel gear 8 is fixedly connected with a screw rod 9, the surface of the screw rod 9 is threadedly connected with a slider 10, and a pull wire 4 is fixedly installed on one side of the slider 10.

[0026] according to Figure 2 It can be seen that the connection module 11 is connected to the motor 5 and the micro switch 12 , so as to supply power to the motor 5 and the micro switch 12 .

[0027] according to Figure 1 It can be seen that the housing 1 has a protruding rectangular box adapted to the slider 10, and the slider 10 is slidably connected to the inside of the rectangular box. When the screw rod 9 rotates to one side, the slider 10 moves to one side on the surface of the screw rod 9 and moves to one side inside the rectangular box.

[0028] The connection module 11 is an EKT, which is used to connect with the EKT after the plug is inserted into the interface 3. The EKT receives current and outputs it to the motor 5. The motor 5 rotates to drive the worm 6 to mesh with the worm wheel 61 to rotate to one side, thereby driving the rotating rod 62 connected to the first bevel gear 7 to rotate to one side, and the first bevel gear 7 and the second bevel gear 8 are meshed, so when the first bevel gear 7 rotates to one side, it drives the second bevel gear 8 connected to the lead screw to rotate to one side, so that the slider 10 moves linearly to one side on the surface of the lead screw 9 to drive the pull wire 4, and the pull wire 4 acts on the ratchet of the lock body to lock the car door. When the slider moves to a specific position, it triggers the micro switch 12, and feeds back a signal to the body BCM, stops supplying current to the motor 5, and the motor 5 stops working.

[0029] Both ends of the rotating rod 62 are rotatably mounted inside the housing 1 , and the surface of the rotating rod 62 is fixedly connected with the worm gear 61 and the first bevel gear 7 .

[0030] The pull wire 4 is slidably connected to the inside of the housing 1 .

[0031] The working principle of the self-priming actuator provided by the present invention is as follows:

[0032] When in use, after the connection module 11 receives current, it outputs it to the motor 5. The motor 5 rotates to drive the worm 6 to engage with the worm wheel 61 to rotate to one side, thereby driving the rotating rod 62 connected to the first bevel gear 7 to rotate to one side, and the first bevel gear 7 and the second bevel gear 8 are engaged, so when the first bevel gear 7 rotates to one side, it drives the second bevel gear 8 connected to the screw rod to rotate to one side, so that the slider 10 moves linearly to one side on the surface of the screw rod 9 to drive the pull wire 4. The pull wire 4 acts on the ratchet of the lock body to lock the car door. When the slider moves to a specific position, it will trigger the micro switch 12, and feedback the signal to the vehicle body BCM, stop supplying current to the motor 5, and the motor 5 stops working.

[0033] Compared with the related art, the self-priming actuator provided by the present invention has the following beneficial effects:

[0034] The present invention provides a self-priming actuator, which enables a slider 10 to move on the surface of the screw 9 and trigger a micro switch 12 by cooperating with a motor 5, a worm 6, a worm wheel 61, a rotating rod 62, a first bevel gear 7, a second bevel gear 8 and a screw 9. Thus, by replacing a large motor with a small motor, a complex transmission chain is simplified into a screw transmission, which saves internal space, greatly reduces the volume and weight of the product, reduces the number of parts, reduces costs, improves production efficiency, makes the transmission structure more reliable, and improves the overall performance of the product.

[0035] Second embodiment

[0036] Please refer to Figure 3 Based on the self-priming actuator provided by the first embodiment of the present application, the second embodiment of the present application proposes another self-priming actuator. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0037] Specifically, the difference of the self-priming actuator provided in the second embodiment of the present application is that, in the self-priming actuator, two fixing grooves 13 are provided inside the interface 3, two fixing blocks 14 are slidably connected inside the two fixing grooves 13, and two fixing springs 15 are provided inside the two fixing grooves 13.

[0038] Four fixing springs 15 are disposed at one end of the four fixing blocks 14 and are respectively located inside the two fixing grooves 13 .

[0039] The four fixing springs 15 are used to push the four fixing blocks 14 to move toward the middle inside the two fixing grooves 13 respectively, so that the four moving rods 16 drive the two limiting rods 17 to be stuck on the surface of the plug inserted into the interface.

[0040] One side of the four fixed blocks 14 is fixedly connected with a moving rod 16 , and one side of the four moving rods 16 is provided with two limiting rods 17 .

[0041] Two ends of the two limiting rods 17 are fixedly connected to one side of the four moving rods 16 respectively.

[0042] The limiting rod 17 is a U-shaped rod, which is used to limit the two limiting rods after they are stuck on the insertion surface inserted into the interface, thereby increasing the stability of the connection.

[0043] The working principle of the self-priming actuator provided by the present invention is as follows:

[0044] When in use, the two limiting rods 17 are moved upward and downward respectively, thereby driving the multiple moving rods 16 connected to the multiple fixing blocks 14 to move upward and downward in the multiple fixing grooves 13 respectively, and at the same time, the multiple fixing springs 15 are squeezed respectively.

[0045] When the plug is inserted into the interface 3, by loosening the two limit rods 17, the multiple fixing springs 15 push the multiple fixing blocks 14 to move toward the middle inside the two fixing grooves 13, thereby driving the multiple moving rods 16 connected to the multiple limit rods 17 to move to the middle to a suitable position, and then the two limit rods 17 can be clamped on the plug.

[0046] Compared with the related art, the self-priming actuator provided by the present invention has the following beneficial effects:

[0047] The present invention provides a self-priming actuator, which cooperates with multiple fixing blocks 14, multiple fixing springs 15 and multiple moving rods 16 through two fixing grooves 13, so that two limit rods 17 can be stuck on the surface of the plug inserted into the interface 3, thereby increasing stability during operation.
