[0040] Figure 1 and Figure 2 It is a schematic structural diagram of a self-priming main push rod according to an embodiment of the present disclosure.

[0041] like Figure 1 and Figure 2 As shown, the present disclosure provides a self-priming main push rod 100, which can cooperate with the suction pull wire 200 when in use, that is, the suction pull wire 200 can be connected to the self-priming main push rod 100, wherein the suction pull wire 200 includes a steel wire rope 210 and a column head arranged at one end of the steel wire rope 210, and accordingly, the other end of the steel wire rope 210 is connected to a winding component driven by a motor, and at least a portion of the steel wire rope 210 can be wound around the winding component. More preferably, the column head can be a zinc column head.

[0042] The self-priming main push rod 100 may include components such as a plate body 110 , a guide portion 120 , and a mounting portion 130 .

[0043] In the present disclosure, the plate body 110 includes a first end 111, a second end 112 and a corner 113; wherein, the connection line between the first end 111 and the corner 113 and the connection between the second end 112 and the corner 113 are at a preset angle. In a preferred embodiment, the angle can be an angle slightly larger than 90°. More preferably, the distance between the first end 111 and the corner 113 is greater than the distance between the second end 112 and the corner 113, and the self-priming main push rod 100 can rotate around an axis in the corner 113, whereby, when the self-priming main push rod 100 is pulled by the suction pull wire 200, it has a larger lever arm and can save more effort.

[0044] The guide portion 120 is located at the first end portion 111 of the plate body 110 ; thus, the guide portion 120 can be away from the corner portion 113 , and the position setting of the guide portion 120 enables the suction pull wire 200 to have a larger force arm.

[0045] In one embodiment, the guide portion 120 has an axis. Preferably, the outer surface of the guide portion 120 is formed as an annular surface. At this time, one end of the guide portion 120 in the axial direction is arranged on the plate body 110, and the other end of the guide portion 120 in the axial direction is away from the plate body 110 by a preset distance, so that in the axial direction, the guide portion 120 has a predetermined size.

[0046] More preferably, the axis of the guide portion 120 is perpendicular or approximately perpendicular to the plate body portion 110; moreover, at least a portion of the surface of the guide portion 120 is formed as a recessed portion, and a portion of the steel wire rope 210 is located in the recessed portion. Thus, through the provision of the recessed portion, the suction pull wire 200 can move closely against the recessed portion, thereby effectively preventing the suction pull wire 200 from detaching from the guide portion 120 during movement, causing a malfunction of the door lock.

[0047] In the present disclosure, when the outer surface of the guide portion 120 is formed as an annular surface, the recessed portion is formed as an annular groove. In the present disclosure, along the axial direction of the guide portion 120, the recessed portion is approximately in the middle of the guide portion 120, thereby increasing the difficulty of the pull wire 200 to be disengaged.

[0048] The mounting portion 130 is disposed on the plate body 110 , and the column head 220 is disposed on the mounting portion 130 , and enables the steel wire rope 210 to contact at least a portion of the outer surface of the guide portion 120 , so as to guide the steel wire rope 210 through the guide portion 120 .

[0049] Specifically, Figure 1As shown, the side wall of the plate body 110 is provided with a first opening, and the circumference of the mounting portion 130 is provided with a second opening, and the first opening and the second opening are arranged correspondingly along the axis of the mounting portion 130. That is, the first opening and the second opening have substantially the same size and are larger than the diameter of the wire rope, and the first opening and the second opening are arranged aligned in the axial direction.

[0050] There is a gap between at least part of the mounting portion 130 and the plate body 110, and the gap is configured to allow the steel wire rope 210 to pass therethrough. In actual use, the column head 220 of the suction pull wire 200 can be inserted into the central hole of the mounting portion 130 along the axial direction, at which time the steel wire rope 210 can move freely in the first opening and / or the second opening. When the column head 220 moves to a suitable position, the steel wire rope 210 is moved to the gap between the mounting portion 130 and the plate body 110, at which time the column head 220 will rotate to a preset angle, and the fixing of the column head 220 is completed. More preferably, the gap is configured so that when the suction pull wire 200 is operated, the steel wire rope 210 of the suction pull wire 200 will not touch the side wall of the gap.

[0051] In the present disclosure, the first opening and the second opening are both facing the outside of the plate body 110, thereby facilitating the installation of the suction wire. Moreover, the sizes of the first opening and the second opening are both smaller than the size of the column head 220. Preferably, the sizes of the first opening and the second opening are both smaller than the diameter of the column head 220, thereby preventing the column head 220 from falling out of the first opening and the second opening.

[0052] In one embodiment, the center hole of the mounting portion 130 and the column head 220 have substantially the same diameter. Preferably, the diameter of the center hole of the mounting portion 130 is slightly larger than the diameter of the column head 220 , thereby enabling the column head 220 to be conveniently installed in the mounting portion 130 .

[0053] At the same time, the plate body 110 also has a receiving portion, and the first opening is the opening of the receiving portion. Similarly, the receiving portion can be formed into a roughly circular shape, and the receiving portion can have roughly the same size as the center hole of the mounting portion 130, so that when the column head 220 is installed, the column head 220 will not shake.

[0054] In a specific embodiment, the plate body 110 further includes a corner 113, and the mounting portion 130 is located between the corner 113 and the second end 112. More preferably, the region between the corner 113 and the first end 111 of the plate body 110 has a first side wall and a second side wall, wherein the first side wall is a side wall away from the second end 112, and the second side wall is a side wall close to the second end 112. In this case, the mounting portion 130 is disposed near the second side wall, and accordingly, the first opening is an opening formed on the second side wall.

[0055] Therefore, when the self-priming main push rod 100 disclosed in the present invention is in use, the self-priming main push rod 100 is grasped and reset by tightening and relaxing the suction wire 200, and at the same time, the relative movement between the self-priming main push rod 100 and the column head 220 of the suction wire 200 is avoided, so that no friction is generated between the column head 220 and the self-priming main push rod 100, and the zinc column head will not be worn or the wear is very small, which further reduces the risk of failure of the door lock function.

[0056] That is to say, through the structural design of the self-priming main push rod 100 disclosed in the present invention, the wear problem between the self-priming main push rod of the side door suction lock and the column head 220 of the suction pull wire is solved, the risk of failure of the suction and locking function is reduced, and the reliability of the side door suction and locking function is enhanced.

[0057] In the present disclosure, the plate body portion 110 , the guide portion 120 and the mounting portion 130 can be integrally stamped and formed, thereby reducing the manufacturing cost of the self-priming main push rod 100 of the present disclosure.

[0058] Figure 3 It is a schematic structural diagram of a vehicle door lock according to an embodiment of the present disclosure.

[0059] According to another aspect of the present disclosure, Figure 3 As shown, the present disclosure provides a vehicle door lock, which can be a side door suction lock, and the side door suction lock includes the above-mentioned self-priming main push rod 100.

[0060] More specifically, a through hole is opened at the corner of the self-priming main push rod 100, and the door lock includes a base plate, on which a shaft is arranged, and the shaft is inserted into the through hole, so that the self-priming main push rod 100 can rotate relative to the base plate, thereby realizing the suction and locking operation, etc.
