DETAILED DESCRIPTION

[0027] The following will be combined with the drawings of the utility model specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In a specific embodiment of the present invention, Figure 1-7 As shown, a hidden lock structure of an automobile inner top inspection door comprises an automobile inner top body 1, an inspection door 2 and a lock assembly 3. The inspection door 2 is arranged in the automobile inner top body 1, and one side of the inspection door 2 is rotatably connected to the automobile inner top body 1, and a plurality of inspection holes 21 are opened on the inner wall of the other side. Specifically, in this embodiment, there are three inspection holes 21 arranged in the same straight line;

[0029] like Figure 2-5As shown, the lock assembly 3 includes a lock 31, a fixed cover 32, a shock absorbing block 33 and a pad 34. The lock 31 is a three-corner / four-corner lock. The lock 31 has several locks and is installed in each inspection hole 21 from the outside of the inspection door one by one. The aperture of the inspection hole 21 is larger than the outer diameter of the lock hole 311 of the lock 31 by 1 mm. The lock core 313 of the lock 31 is located in the inspection hole 21. The fixed cover 32 is sleeved on the lock 31 and pressed against the inner wall of the inspection door 2. The fixed cover 32 and the inspection door 2 are fixed by glue. The shock absorbing block 33 is sleeved on the lock tongue 312 of the lock 31 and fixed therebetween. The pad 34 is fixedly arranged on the inner wall of the inner top body 1 of the automobile and is located below the shock absorbing block 33. The structure has good concealment.

[0030] In the present embodiment, the glue is a single-component structural glue, specifically, Sika glue 221 can be selected. When the lock is damaged, there is no need to destroy the inspection door. By adopting high-temperature baking above 80°C, the glue can be peeled off to quickly separate the fixed cover from the inspection door, making it easy to replace the three / four-corner lock and improving the speed of lock replacement.

[0031] In this embodiment, a locking nut 4 is provided on the lock 31 , and the locking nut 4 is arranged on the outside of the fixing cover 32 , which can strengthen the contact between the lock and the fixing cover and reduce abnormal noise during the driving of the car.

[0032] In this embodiment, the shock absorbing block 33 and the pad 34 are made of rubber, which can prevent the lock from making abnormal noises due to bumps when the car is in a locked state, thereby reducing noise and improving protection for the lock tongue.

[0033] like Figure 6 As shown, in this embodiment, the shock absorbing block 33 includes an arc segment 331, a rectangular segment 332 and a cylindrical segment 333 integrally formed from top to bottom, a mounting groove 334 is provided between the arc segment 331 and the rectangular segment 332, the lock tongue 312 extends into the mounting groove 334 and is fixed by glue, a plurality of through holes 3321 are provided in the rectangular segment 332, and the cylindrical segment 333 has at least two through holes and the bottom surface is an arc surface. Through the design of the mounting groove, the lock tongue and the shock absorbing block can be quickly installed, and the design of the through hole here is not only for exhaust in the shock absorbing block production process, but also can play a buffering role in the downward compression process of the shock absorbing block; in addition, the design of the cylindrical segment and the bottom arc surface here can reduce the friction between the shock absorbing block and the pad, and increase the service life of the shock absorbing block.

[0034] In this embodiment, the materials of the car's inner top body 1, the inspection door 2 and the fixed cover 32 are all fiberglass. This design meets the light-proof design requirements of the vehicle industry. This light-proof design eliminates the possibility of passengers throwing debris in, causing the lock to be damaged and causing inconvenience in inspection.

[0035] The installation process of this embodiment is as follows:

[0036] The lock 31 is passed through the fixing cover 32, and glue is applied to the side where the fixing cover 32 and the inspection door 2 are in contact. Then, the fixing cover 32 is pressed down and the unlocking end of the lock 31 is pressed against the inner wall of the inspection door 2 at the same time. Then, the locking nut 4 is locked on the outer side of the fixing cover 32, and the lock tongue 312 is installed through the nut. Then, glue is applied to the upper and lower sides of the lock tongue 312 and then extended into the installation groove 334. After the glue is cured, the fixation of the lock tongue 312 and the shock absorbing block 33 can be completed. Then, glue is applied to one side of the pad 34 and bonded to the inner wall of the inner top body 1 of the automobile. In this way, the entire hidden lock structure is installed. The utility model has good concealment, improves the overall aesthetics of the inner top body and the inspection door of the automobile, makes the overall appearance consistent, and prevents passengers from putting debris into the keyhole, causing the lock to be damaged and causing inconvenience in maintenance.

[0037] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
