Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive door lock cover. Background Technology
[0002] Car door locks can be structurally divided into three layers: the first layer is the cover plate, the second layer is the claw support component (plastic body component), and the third layer is the base plate component (lock body component). The cover plate and claw support constitute the locking mechanism of the lock body to achieve the locking function. The base plate is used to achieve the inward and outward opening functions and the inward and outward locking / unlocking functions. During assembly, the base plate of the door lock is assembled first, then assembled with the claw support component. Finally, the cover plate is assembled on the claw support and connected to the third base plate component with screws. The stop claw and the locking plate need to be riveted to the cover plate first, and then assembled together with the cover plate onto the claw support.
[0003] However, the aforementioned documents and existing cover plates lack a sealing structure between the cover plate and the lock body. During long-term use, moisture or dust can easily enter the interior through the gap between the cover plate and the lock body, thus affecting the user's normal experience. In addition, the cover plate lacks a positioning structure, which means that during assembly, the staff must manually align the cover plate with the lock body and tighten the screws to complete the installation. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an automotive door lock cover that can improve the sealing performance between the cover plate and the lock body, addressing the shortcomings of the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a car door lock cover plate, comprising a cover plate body, characterized in that: a sealing groove is formed on the lower end face of the cover plate body near its edge, a sealing strip is embedded in the sealing groove, a plurality of embedded grooves are provided along the bottom of the sealing groove, and an embedded block adapted to the embedded groove is provided at the lower end of the sealing strip.
[0006] The above technical solution, compared with the prior art which lacks a sealing structure between the cover plate body and the lock body, provides a sealing groove on the lower end face of the cover plate body, with a sealing strip embedded in the groove. When the cover plate body is installed on the lock body, the sealing strip is located between the cover plate body and the lock body, providing a sealing structure to prevent moisture, dust, and other foreign objects from entering the lock body through edge gaps. At the same time, the embedded groove and embedded block ensure that the embedded block is installed into the embedded groove when the sealing strip is assembled, which can improve the installation firmness of the sealing strip, prevent the sealing strip from shifting position, and reduce the sealing effect.
[0007] A further feature of this invention is that the cover plate body has at least two downwardly extending positioning blocks along its edge, and the upper end of the positioning blocks is connected to the cover plate body through an arc surface.
[0008] The above technical solution is adopted: by setting the positioning block, the cover plate body inserts the positioning block into the corresponding positioning groove on the lock body during assembly, which can play a positioning role and make it easier for workers to tighten the screws.
[0009] A further feature of this invention is that the cover plate body has two through-holes and several through-holes.
[0010] The above technical solution facilitates the riveting of the stop pawl and the locking plate by setting the riveting hole, while the threaded hole is used for screw insertion, so that the cover plate body can be installed on the lock body.
[0011] A further feature of this invention is that the lower end face of the cover plate body extends downward from the rivet hole and is provided with a protrusion formed by stamping, and the upper end face of the cover plate body is provided with a groove formed by stamping.
[0012] The above technical solution avoids stress concentration areas caused by splicing or welding by forming protrusions and grooves through stamping, resulting in better fatigue and impact resistance. At the same time, the protrusions can fit more closely with the lock body components, reducing the gap between them.
[0013] A further feature of this invention is that a rubber sleeve is fitted over the protrusion, and the protrusion has a plurality of mounting protrusions along its outer wall, with each mounting protrusion evenly distributed on the outer wall of the protrusion.
[0014] The above technical solution addresses the following: In the prior art, when the stop claw and the clamping plate are riveted, the stop claw and the clamping plate will directly collide with the protrusion. Since all three are made of metal, if the riveting force is too great, the collision between the metals will cause deformation between them. By setting up the rubber sleeve, a certain buffering effect can be achieved to avoid direct collision between the metals. At the same time, by setting up the convex strip, the friction between the protrusion and the rubber sleeve is increased, thereby improving the firmness between the two.
[0015] A further feature of this invention is that the rubber sleeve has a through hole corresponding to the riveting hole.
[0016] The above technical solution is adopted: the installation of the stop claw and the clamping plate is ensured by setting the rivet holes on the rubber sleeve.
[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
