Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an installation latch device for vehicle door modules. Background Technology
[0002] In today's automotive industry, lightweighting and integration of the entire vehicle are key focuses for all car manufacturers. Consequently, the lightweighting and integration of numerous components have become major challenges in the industry. Major components within a car door include window regulators, door locks, speakers, and more. Many current models integrate these into the door module, optimizing the interior space layout and effectively reducing the door's weight. While the installation methods for door modules and door panels vary, many suffer from drawbacks such as difficulty in installation, improper installation, time-consuming processes, and susceptibility to damage. Summary of the Invention
[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses an installation locking device for vehicle door modules.
[0004] Technical solution: The mounting latch device for vehicle door modules disclosed in this utility model includes: the mounting latch device includes a latch body, a washer, and a latch mounting plate;
[0005] The latch body includes an outer latch disc, an inner latch disc on the inner ring of the upper surface of the outer latch disc, and a washer setting position on the outer ring of the inner latch disc on the upper surface of the outer latch disc. The middle of the inner latch disc extends upward to form a locking shaft, and the outer end of the locking shaft forms a rectangular lock head. The lock head has grooves on both sides in the width direction, and outward-facing claws are provided in the grooves. The height of the claws is lower than that of the lock head.
[0006] The buckle mounting plate includes a buckle plate body, which has a rectangular lock hole through which the lock head passes. The lock hole has U-shaped slots with corresponding claws on both sides in the width direction. When the lock head passes through the lock hole and presses the washer onto the buckle mounting plate, the claws are axially locked in the U-shaped slots, realizing the pre-installation of the buckle. The outer edge of the U-shaped slot has an arc corner structure. By rotating the buckle body, the lock head and the lock hole are misaligned, realizing the buckle locking.
[0007] A rectangular mounting hole is made in the vehicle door panel corresponding to the lock head. The buckle mounting plate is fixed to the door module, and the vehicle door panel and door module are locked by the buckle body.
[0008] Furthermore, the claw is an elastic claw for pre-installation and fixation, formed by extending obliquely outward from the inner surface of the latch.
[0009] Furthermore, the bottom of the washer is provided with washer bosses at intervals, and the washer setting position on the outer plate of the lock is provided with a boss groove through the washer boss.
[0010] Furthermore, the bottom of the buckle plate is provided with a cylindrical limiting body, the washer is pressed into the inner ring of the cylindrical limiting body, there is an irregular structure in the boss groove forming an indicator, and the outer ring of the cylindrical limiting body is provided with an indicator structure. The degree of rotation of the lock head is judged by the angle change between the indicator structure and the irregular structure in the boss groove.
[0011] Furthermore, a drive column is provided at the bottom of the outer disc of the latch, and the inner ring and outer wall of the drive column are provided with a multi-angle drive structure, so that the latch body is rotated by applying force through the drive column.
[0012] Furthermore, the inner surface of the latch is provided with a protrusion, and the bottom of the latch mounting plate is provided with a recess. After the latch body rotates 90°, the protrusion falls into the recess, and the bottom of the latch mounting plate is provided with a sliding groove corresponding to the movement trajectory of the protrusion.
[0013] Furthermore, the two ends of the lock shaft in the length direction are limiting surface structures. When the lock is in the locked state, the limiting surface structures at both ends fit into the lock hole, restricting its over-rotation.
[0014] Furthermore, the door module is fixed to the vehicle door panel by multiple sets of mounting latches arranged at intervals.
[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are: the door module is installed on the inner door panel of the car door through the installation latch device designed in this invention, realizing the lightweighting of the car door; the structure of the installation latch device enables efficient installation of the door module, which is quick and not easily damaged.

The middle of the inner latch surface 101 extends upward to form a locking shaft 103, and the outer end of the locking shaft 103 forms a rectangular lock head 104. The lock head 104 has grooves 105 on both sides in the width direction, and outwardly facing claws 106 are provided in the grooves 105 respectively. The height of the claws 106 is lower than that of the lock head 104.
[0028] The specific structural form of the chuck 106 is not limited. This embodiment discloses two possible chuck forms:
[0029] One is as follows Figure 8 The first example shows a resilient latch formed by the inner surface 102 of the latch extending obliquely outward for pre-installation and fixation; the second example is as follows: Figure 9 The shown is a convex claw with an arc transition at the upper corner, which is set in the groove 105.
[0030] The latch mounting plate 3 includes a latch plate body 301. The latch plate body 301 has a rectangular lock hole 302 through which the lock head 104 passes. The lock hole 302 has U-shaped grooves 303 on both sides in the width direction corresponding to the claws 106. When the lock head 104 passes through the lock hole 302 and presses the washer 2 against the latch mounting plate 3, ... Figure 2 As shown, the claw 106 is axially locked in the U-shaped slot 303 to achieve pre-installation of the latch. The outer edge of the U-shaped slot 303 is an arc-shaped structure. By rotating the latch body 1, the lock head 104 and the lock hole 302 are misaligned to achieve latch locking.
[0031] The bottom of the washer 2 is provided with washer bosses 201 spaced apart. The washer positions on the outer surface 101 of the latch correspond to the washer bosses 201, with boss grooves 107 extending through them. The bottom of the latch plate 301 is provided with a cylindrical limiting body 304. The washer 2 is pressed against the inner ring of the cylindrical limiting body 304. The boss groove 107 contains a shaped structure forming an indicator. The outer ring of the cylindrical limiting body 304 is provided with an indicator structure 305. The degree of rotation of the lock head 104 is determined by the angle change between the indicator structure 305 and the shaped structure in the boss groove 107. Figure 3 and 4 As shown.
[0032] The bottom of the outer disc 101 of the latch is provided with a drive post 108. The inner ring and outer wall of the drive post 108 are provided with a multi-angle drive structure. The latch body 1 is rotated by applying force through the drive post 108.
[0033] like Figure 5 As shown, the upper surface of the inner disc 102 of the latch is provided with a protrusion 109, and the bottom of the latch mounting plate 3 is provided with a recess 306. After the latch body 1 rotates 90°, the protrusion 109 falls into the recess 306. The bottom of the latch mounting plate 3 is provided with a sliding groove 307 corresponding to the movement trajectory of the protrusion 109.
[0034] The two ends of the locking shaft 103 in the length direction are limiting surface structures 110. When the lock is in the locked state, the limiting surface structures 110 at both ends fit with the lock hole 302, restricting its over-rotation.
[0035] like Figure 6 As shown, a rectangular door panel mounting hole 401 is opened through the door panel 4 corresponding to the lock head 104. The buckle mounting plate 3 is fixed on the door module. The door panel 4 and the door module are locked by the buckle body 1. The door module is fixed to the door panel 4 by multiple sets of mounting buckle devices arranged at intervals.
