DETAILED DESCRIPTION
[0023] Referring to Figures 1-4 The lock body plastic shell 1 includes a connecting portion 10, a thin wall 11 and a movable cover plate 12, and the lock body plastic shell 1 is integrally formed, specifically, the connecting portion 10, the thin wall 11 and the movable cover plate 12 are integrally formed.
[0024] The connecting part 10 is a plastic plate structure and is mounted on the pull cable housing 2 by screws. Further, the connecting part 10 and the pull cable housing 2 are both provided with screw mounting holes.
[0025] The connecting part 10 is connected to the movable cover plate 12 at a thin wall 11. The thickness of the thin wall 11 is 0.3-0.5 mm. The movable cover plate 12 is below the thin wall 11. Further, the movable cover plate 12 is located at the bottom of the door lock body mounting position. Further, the movable cover plate 12 is arranged at the door lock opening pull cable hole 20 position on the pull cable housing 2 and is used to block or open the door lock opening pull cable hole 20.
[0026] In this embodiment, the thin wall 11 structure utilizes the flexibility of plastic. The movable cover plate 12 rotates around the thin wall 11. The rotating state can be divided into an open state or a blocked state of the door lock opening pull cable hole 20.
[0027] Further, when the movable cover plate 12 is buckled at the opening of the door lock opening pull cable hole 20, the movable cover plate 12 blocks the door lock opening pull cable hole 20. The door lock opening pull cable hole 20 is in a blocked state. In this state, the outer surface of the movable cover plate 12 and the outer surface of the connecting part 10 are in the same plane. This does not increase the space of the lock body and does not affect the matching space of the customer. At this time, the opening pull cable is inside the lock body. The movable cover plate 12 fills the gap of the assembly space, i.e., fills the door lock opening pull cable hole 20. This can prevent water and dust from entering the inside of the lock body and protect the service life and performance of the internal moving mechanism.
[0028] When the movable cover plate 12 is separated from the opening of the door lock opening pull cable hole 20, the movable cover plate 12 opens the door lock opening pull cable hole 20. The door lock opening pull cable hole 20 is in an open state. In this state, the door lock opening pull cable is used for detection and installation of the door lock function. In this state, an installation space of not less than a° can be provided. The definition of a° is the angle of deflection of the movable cover plate 12 relative to the connecting part 10. Preferably, the value of a is 70° or more.
[0029] In some embodiments, referring to Figure 1 The connecting part 10 is provided with a limiting connecting rib 100. The end of the limiting connecting rib 100 away from the connecting part 10 is located within the width range of the thin wall 11. The movable cover plate 12 is bent and rotated around the end of the limiting connecting rib 100 away from the connecting part 10.
[0030] Further, the position of the end of the limiting connecting rib 100 away from the connecting part 10 can be changed to change the bending and rotating position of the movable cover plate 12 on the thin wall 11.
[0031] The movable cover plate 12 of the structure is provided with two or more sets of clamping structures 3, which are used for clamping between the movable cover plate 12 and the pull wire shell 2 in the closed state of the door lock opening pull wire opening hole 20. The forms include but are not limited to the recess 30 on the movable cover plate 12, and the corresponding protrusion 31 on the pull wire shell 2; or the protrusion 30 on the movable cover plate 12, and the corresponding recess 31 on the pull wire shell 2.
[0032] Referring to Figure 3 The recess 30 is a clamping structure, and the opening of the clamping structure is provided with an outwardly convex mounting portion, which is in a U shape. In addition, the protrusion 31 is in a wedge shape. When the inclined surface of the wedge-shaped protrusion 31 abuts against the horizontal end of the U-shaped mounting portion, the wedge-shaped protrusion 31 passes through the mounting portion through the deformation of the mounting portion, and the wedge-shaped protrusion 31 is located in the clamping structure, and the horizontal end of the wedge-shaped protrusion 31 is mounted on the horizontal end of the U-shaped mounting portion.
[0033] In some embodiments, the clamping structures 3 are arranged in parallel on the outer edge of the movable cover plate 12, away from the thin wall 11. The clamping structures 3 prevent the movable cover plate 12 from being pulled out of the pull wire shell 2.
[0034] An edge end is arranged on the movable cover plate 12, and preferably, the edge end is located between the clamping structures 3. Further, the pull wire shell 2 is provided with a limiting protrusion 21, which prevents the movable cover plate 12 from continuing to move towards the pull wire shell 2 under external force, limits the movable cover plate 12 to a fixed position, and avoids problems such as position deviation, knocking noise, and the movable cover plate 12 being pulled out. Preferably, the edge 103 is located between the two sets of clamping structures 101.
[0035] The lock body plastic shell 1 of the structure is provided with a drain port 13. Specifically, the drain port 13 and the pull wire shell 2 maintain a sufficient gap, which is to timely drain the water or other liquid substances entering the inside of the lock body under abnormal conditions.
[0036] Preferably, the drain port 13 is arranged at the installation position of the door lock, and is closer to the rear of the vehicle. The purpose is to keep the drain port 13 at the lowest position of the semi-closed space of the lock body, facilitate complete drainage of water, especially in the case that the installation angle of the rear door of the passenger vehicle is relatively large.
[0037] Finally, the setting position of the drain port 13 on the lock body plastic shell 1 is preferably on the connecting portion 10, and is located on one side of the movable cover plate 12.
[0038] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
