Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The central control door lock actuator is arranged at the position of the automobile door lock. After the central control door lock actuator receives the unlocking signal, the central control door lock actuator drives the unlocking component to swing through the driving motor, so that the unlocking of the vehicle door is realized, and the wireless control unlocking of the vehicle door is further realized. That is, when the unlocking member is swung to a specific position, the door is unlocked, and when the unlocking member is swung to another position, the door is locked. The existing central control door lock actuator has a complex structure and low processing efficiency.
In the existing central control door lock actuator, unlocking is realized by utilizing the swinging of an unlocking device, gear teeth arranged in an arc shape are arranged at one end of the unlocking device, the unlocking device is driven to swing by driving a gear mechanism through a motor, and the gear mechanism is meshed with the gear teeth on the unlocking device. The structure in the prior art drives the unlocking period to swing forwards and backwards through the forward and reverse rotation of the motor. In order to match the swing stroke of the unlocking device, in the prior art, when the unlocking device is installed, the gear teeth on the unlocking device and the gear teeth in the gear mechanism need to be aligned, if the unlocking device can only swing by a small arc, the unlocking position cannot be reached, or the unlocking device swings to the unlocking position, the driving motor still rotates, and the assembly process of the unlocking device is troublesome.
In view of this, as shown in fig. 1 to 4, the present application provides a central control door lock actuator, which includes a housing 600, a driving motor 500, and a transmission assembly including a worm 100, a worm wheel 200, a transmission rod 300 (i.e. the unlocking device in the foregoing) and an elastic member (not shown in the drawings), wherein the worm 100 is connected to a rotating shaft of the driving motor 500. The worm 100 in combination with the drive motor 500 forms a drive assembly. The worm wheel 200 is engaged with the worm 100. The abutting portion is connected to the worm wheel 200, is configured to rotate following the worm wheel 200, and is a cam 400, and the rotation axis of the cam 400 coincides with the rotation axis of the worm wheel 200. The middle portion of the transmission rod 300 is hinged to the housing 600, and the transmission rod 300 is configured to rotate from a first operating position to a second operating position (i.e., the transmission rod 300 can lock the vehicle door when in the first operating position and unlock the vehicle door when in the second operating position). The elastic member connects the housing 600 and the transmission lever 300 and is configured to generate an elastic force for rotating the transmission lever 300 from the second operating position to the first operating position. After the transmission rod rotates to the second working position, the elastic member pulls the transmission rod 300 back to the first working position. Wherein the worm 100 can drive the worm wheel 200 in a first rotation direction, and the abutting portion is configured to push the transmission rod 300 to rotate from the first working position to the second working position in a rotation stroke following the rotation of the worm wheel 200 in the first rotation direction.
When the central control door lock actuator receives an unlocking signal, the driving motor 500 drives the worm 100 in the application to rotate, and further drives the worm wheel 200 to rotate, so as to complete the speed reduction step. The worm gear 200 drives the abutting part connected with the worm gear to rotate, and the driving rod 300 is pushed to rotate to the second working position in the rotating process of the abutting part (it can be understood that the vehicle door can be locked when the driving rod 300 rotates to the first working position, and the vehicle door can be unlocked when the driving rod 300 rotates to the second working position), so that the vehicle door can be unlocked.
Technical scheme in this application, because adopt the structure of cam 400 butt transfer line 300 and then promote transfer line 300 and rotate to the second operating position by first operating position, for the technical scheme who adopts both gear engagement among the prior art, need not accurate alignment both outer teeth at the in-process of assembly for the assembly process becomes more convenient. And the structure using the cam 400 allows the swing process of the driving lever 300 to be more linear.
According to some embodiments, the abutment is configured to urge the drive rod 300 to rotate from the first operative position to the second operative position upon rotation of the worm gear 200 in the first rotational direction within the first rotational range, and to disengage from the drive rod 300 upon rotation in the first rotational direction beyond the first rotational range. That is to say, in this application, because of having the elastic component, when making the butt portion not butt the transfer line 300, the transfer line 300 can reset by oneself, so driving motor 500 in this application can also realize the swing of two directions of transfer line 300 without just reversing, after the butt portion butt transfer line 300 reaches the second working position, continues to rotate along the present direction of rotation again, after the butt portion breaks away from with transfer line 300, transfer line 300 just resets to first working position because of the elasticity of elastic component.
Of course, in another embodiment, the worm 100 is configured to drive the worm gear 200 in a second rotational direction, which is opposite to the first rotational direction. That is, the driving motor 500 can control the transmission lever 300 by forward and reverse rotation.
According to some embodiments, the drive rod includes a drive end for abutting against the abutment and a drive end for outputting power outwardly.
The elastic member may be a spring or a leaf spring, and the elastic member may be connected to the driving end of the driving rod 300, or may be connected to the driving end of the driving rod 300, according to some embodiments, the elastic member is connected to the driving end.
In a preferred embodiment, the elastic member is a torsion spring, and the torsion spring is connected to the rotation center of the driving lever 300.
In the above embodiment, the abutting portion is the cam 400, and in order to improve the transmission efficiency, the abutting portion may include a plurality of cams 400, and the plurality of cams 400 are arranged in a circular array, so that the worm wheel 200 rotates once to perform the unlocking operation a plurality of times.
In one embodiment, the abutting portion can be an abutting rod 710, one end of the abutting rod 710 is connected to the rotation center of the worm gear 200, and the other end is used for abutting the transmission rod 300. The structure of the abutting rod 710 is simpler and less costly than the cam 400.
In order to reduce the friction between the abutting rod 710 and the transmission rod 300, an abutting wheel 720 may be further provided at the end of the abutting rod 710 facing away from the worm wheel 200, and the abutting wheel 720 is rotatably connected with the abutting rod 710. Thus, the contact roller 720 and the transmission rod 300 do not have rolling friction, so that the process of pushing the transmission rod 300 can be smoother, and the abrasion can be reduced.
Likewise, in order to improve the transmission efficiency, the abutment may further include a plurality of transmission rods 300, and specifically, the abutment includes four transmission rods 300, one ends of the four transmission rods 300 are simultaneously connected together and connected to the rotation center of the worm wheel 200, and the ends of the four transmission rods 300 may be respectively connected to the abutment wheels 720, so that one rotation of the worm wheel 200 enables four unlocking operations. In particular, four transmission rods 300 can also be arranged along a circular array of centers of rotation, forming a cross.
