[0002] Automotive door interior panels are panel-type components that cover the inside of car doors. They mainly serve to decorate and protect the internal structure of the door, and may also contain functional components such as window switches.

[0003] Chinese Patent No. CN223370766U discloses an easy-to-install automotive door interior panel, including an interior panel. A clamping mechanism is fixedly connected to the front of the mounting assembly. Several transmission mechanisms are threadedly connected at intervals on the upper and lower sides of the bearing mechanism away from the clamping mechanism. Several locking mechanisms are slidably connected at intervals on the upper and lower sides of the bearing mechanism near the clamping mechanism. Spring-back mechanisms are symmetrically fixedly connected to the left and right sides of the locking mechanisms.

[0004] The clips, which are the core connecting components, are mostly made of plastic. When repeatedly disassembled or improperly operated, the internal stress concentration structures (such as barbs and claws) are prone to breakage or plastic deformation. This directly leads to loosening of the connection point and induces abnormal noise when the vehicle is bumpy. Moreover, the entire clip assembly needs to be replaced during maintenance, which increases maintenance costs. In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Please see Figure 1-5 As shown, this embodiment provides an easily detachable automotive door interior panel, comprising: Decorative panel body 1; Multiple snap-fit ​​posts 2, each snap-fit ​​post 2 includes a base 21, with a mounting stud 22 on one side of the base 21. The base 21 is screwed onto the main body 1 of the decorative panel by the mounting stud 22. One end of the base 21 is threaded with a threaded sleeve 27. Two spring pieces 28 are provided on one side of the threaded sleeve 27. A rotating shaft 23 is elastically fitted inside the base 21. A traction cable 5 is wound around the outside of the rotating shaft 23. A clamping stud 25 is fixedly installed at one end of the rotating shaft 23. The clamping stud 25 is rotatably fitted with the base 21. A top seat 26 is threaded on the outside of the clamping stud 25. The top seat 26 is fitted with one side of the spring piece 28. The winding seat 3, one end of the traction cable 5 is wound up inside the winding seat 3; The guide rail 4, the traction cable 5, and the guide rail 4 are in sliding fit.

[0021] Working principle: During installation, the base 21 is screwed into the decorative panel body 1 using the mounting stud 22, and the spring piece 28 is installed on the base 21 through the screw sleeve 27. One end of the traction cable 5 is wound into the rotating shaft 23, and the other end is installed and wound into the winding seat 3. At the same time, the traction cable 5 slides along the inner side of the guide rail 4. During operation, the winding seat 3 is rotated to wind up the traction cable 5, which pulls the rotating shaft 23 to rotate, thereby driving the clamping stud 25 to rotate. The clamping stud 25 pushes the top seat 26 to move through the threaded transmission, so that the top seat 26 pushes open the spring piece 28 and locks it onto the door. During disassembly, the retractor 3 is rotated in the opposite direction to release the traction cable 5. The spring force drives the rotating shaft 23 to reverse, thereby rewinding the traction cable 5. At the same time, the rotating shaft 23 drives the clamping stud 25 to reverse, causing the top seat 26 to reset. The spring piece 28 returns to its original position under its own elastic force, and can then be removed from the door. If the spring piece 28 is damaged, the damaged spring piece 28 can be replaced simply by unscrewing the screw sleeve 27, without having to replace the entire locking post 2, thus reducing costs. When disassembling and assembling the locking post 2, it is only necessary to unscrew the locking post 2 by installing the stud 22, making the disassembly and assembly process simple and quick.

[0022] In this embodiment, the surface of the decorative panel body 1 is provided with a switch opening 11, and a storage cavity 12 is provided on one side of the decorative panel body 1. The winding seat 3 is installed inside the storage cavity 12. One side of the top seat 26 is set with an arc-shaped structure, and two positioning posts 24 are fixedly installed on the other side of the top seat 26. Both positioning posts 24 are slidably engaged with the base 21. The screw sleeve 27 is set with an annular structure, and two spring pieces 28 are symmetrically installed on one side of the screw sleeve 27.

[0023] During installation, the top seat 26 moves axially along the clamping stud 25 under the guidance of the positioning pin 24. The arc-shaped structure at its top smoothly pushes open the spring clip 28, reliably locking it onto the door. When the spring clip 28 needs to be replaced, simply unscrew the threaded sleeve 27 to remove and replace the damaged spring clip.

[0024] The winding holder 3 in this embodiment includes a winding box body 31, which is fixed inside the storage cavity 12. One end of the traction cable 5 is elastically fitted onto the inner side of the winding box body 31 and a winding shaft 33. A knob 34 is fixedly installed on one end of the winding shaft 33. An inlet and outlet 32 ​​is provided on one side of the winding box body 31. A ratchet 35 is fixedly installed on one end of the winding shaft 33. A pawl 36 is engaged on one side of the ratchet 35. The pawl 36 is elastically fitted with the winding box body 31. A sliding sleeve 37 is slidably fitted on one side of the pawl 36. A pull rod 38 is rotatably fitted on one side of the sliding sleeve 37. The pull rod 38 is slidably fitted with the winding box body 31.

[0025] Locking process: Rotate knob 34 to drive take-up shaft 33 to rotate and take up traction cable 5. The cable then drives top seat 26 to push open spring piece 28, making it stably locked onto the door. At this time, pawl 36 engages with ratchet 35 under the action of locking mechanism to prevent take-up shaft 33 from reversing and ensure stable locking state; Release process: Pull the lever 38, which causes the sliding sleeve 37 to push the pawl 36 off the ratchet 35. After the lock is released, under the action of the spring force, the winding shaft 33 rotates in the opposite direction to release the traction cable 5. At the same time, the top seat 26 resets, and the spring piece 28 also retracts under its own elastic force, completing the unlocking.

[0026] The guide rail 4 in this embodiment includes a mounting tube 41, which is fixedly installed on one side of the decorative panel body 1. Multiple mounting slots 42 are opened on one side of the mounting tube 41, and the snap-on post 2 cooperates with the mounting slot 42. Multiple protective posts 43 and multiple guide posts 44 are fixedly installed on the inner side of the mounting tube 41. The positions of the protective posts 43 correspond to the positions of the mounting slots 42, and the multiple guide posts 44 are symmetrically installed in pairs on the inner side of the mounting tube 41.

[0027] The traction cable 5 is slidably installed in the installation tube 41 by the guide post 44, and the position of the buckle post 2 is guided by the protective post 43 to guide the traction cable 5, reducing the phenomenon of the traction cable 5 pressing on the buckle post 2 when it slides, and ensuring that the traction cable 5 slides stably when passing the buckle post 2.

[0028] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
