[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an easily detachable automotive accessory, including a headrest 1. Insert rods 2 are fixedly connected to both ends of the bottom of the headrest 1. Multiple limiting holes 16 are provided at the rear bottom of the insert rods 2. The insert rods 2 are connected to a seat back 3 via an insertion port 4. A sleeve 5 is fixedly connected to the top side of the inner wall of the seat back 3. Multiple limiting holes 15 corresponding to the limiting holes 16 are provided at the rear bottom of the sleeve 5. A through hole 7 is provided at the top front of the seat back 3. A cavity 8 is installed inside the seat back 3. Limiting grooves 11 are provided at the rear ends of both sides of the cavity 8. A sliding groove 9 is provided on the front side of the cavity 8. A slider 10 is slidably connected to the inner wall of the sliding groove 9. Extension blocks 12 are fixedly connected to the rear ends of both sides of the slider 10. The extension blocks 12 are slidably connected to the limiting grooves 11. Limiting pins 13 are fixedly connected to the outer front ends of the extension blocks 12. A spring 14 is fixedly connected to the rear side of the slider 10. The bottom insertion rod 2 of the headrest 1 is convenient to be inserted into the insertion port 4 of the backrest 3 and cooperate with the sleeve 5. Multiple limiting holes 16 at the bottom rear side of the insertion rod 2 cooperate with the limiting hole 15 of the sleeve 5 and the locking assembly composed of the slider 10, extension blocks 12, limiting pins 13 and springs 14. When the spring 14 pushes the slider 10 to insert the limiting pins 13 into the limiting holes 16 and 15, the insertion rod 2 can be accurately positioned in the sleeve 5. The design ensures the firmness and stability of the connection between the headrest 1 and the chair back 3, preventing the headrest 1 from shaking or falling off. It also allows for the application of force to the slider 10 to overcome the spring force of the spring 14, causing the slider 10 to slide along the slide groove 9. This drives the extension block 12 to move within the limiting groove 11, allowing the limiting pin 13 to exit from the second limiting hole 16 and the first limiting hole 15. This allows the insertion rod 2 to smoothly disengage from the sleeve 5, enabling convenient disassembly of the headrest 1 and improving its flexibility and convenience. Furthermore, the stable connection ensures seating comfort and safety during normal use. The sleeve 5 is fixed to the top side of the inner wall of the chair back 3, providing insertion space for the insertion rod 2 and limiting its movement. The positioning hole 15 engages with the insertion rod 2 to achieve locking, ensuring the stability of the headrest 1's position, and serves as a channel for the insertion rod 2 to be pulled out during disassembly; the through hole 7 provides a path for the limiting pin 13 to pass through to lock the insertion rod 2 and the sleeve 5, ensuring reliable connection, and provides space for the limiting pin 13 to exit during disassembly; the cavity 8 accommodates related components, and its limiting groove 11 engages with the extension block 12 of the slider 10 to limit the movement range of the slider 10, so that the limiting pin 13 can be accurately inserted and withdrawn, ensuring that the connection and disassembly of the headrest 1 and the chair back 3 can be carried out normally; the slide groove 9 provides a sliding track for the slider 10, so that the slider 10 can move in a predetermined direction to drive the limiting pin 13 to move.

[0027] Reference Figures 2-4A washer 18 is fixedly connected to the top outer side of the insert rod 2. The top of the washer 18 fits against the bottom of the headrest 1. The washer 18 can buffer the pressure between the headrest 1 and the insert rod 2, avoid local wear, and make the connection tighter. The insert rod 2 is slidably connected to the sleeve 5. Sealing rings 17 are fixedly connected to the top left and right ends of the chair back 3. The inner side of the sealing ring 17 fits against the outer side of the insert rod 2. The sealing ring 17 can effectively prevent dust and other impurities from entering the connection between the insert rod 2 and the sleeve 5, extend the service life of the components, and enhance the connection stability. The width of the through hole 7 is the same as that of the slider 10. The slider 10 and the through hole 7 are slidably connected. A soft pad is fixedly connected to the front side of the slider 10. The width of the through hole 7 is the same as that of the slider 10 and is slidably connected, providing precise guidance for the movement of the slider 10. When the spring 14 on the rear side of the slider 10 pushes the slider 10, its left side... The right-side rear extension blocks 12 slide smoothly within the left and right rear limit grooves 11 of the cavity 8, thereby driving the front-side fixed limit pins 13 to accurately insert or withdraw from the limit hole 2 16 at the rear bottom of the insert rod 2 and the limit hole 15 at the rear bottom of the sleeve 5, realizing the locking or unlocking of the headrest 1 and the chair back 3. The soft pad fixed to the front of the slider 10 facilitates operation and has a certain buffering effect. The outer bottom of the sleeve 5 is fixedly connected to the fixing rod 6, which is connected to the left and right sides of the inner wall of the chair back 3, enhancing the stability of the sleeve 5 in the chair back 3 and ensuring the reliability of the connection between the insert rod 2 and the sleeve 5. The front of the cavity 8 fits against the front of the inner wall of the chair back 3, providing a stable installation space for the internal slider 10 and other components, ensuring the smooth operation of the components and making the connection and disassembly mechanism of the headrest 1 and the chair back 3 operate stably.

[0028] Working principle: First, by applying a backward pushing force to the slider 10, the slider 10 moves backward along the slide groove 9. The left and right rear extension blocks 12 slide within the left and right rear limiting grooves 11 of the cavity 8. Then, the bottom insertion rod 2 of the headrest 1 is aligned with the insertion port 4 of the chair back 3 and inserted. As the insertion rod 2 slides into the sleeve 5, the pushing force on the slider 10 is released, and the spring 14 pushes the slider 10 forward with a forward elastic force. This causes the limiting pin 13, which is fixedly connected at the front, to pass through the through hole 7 and insert into the limiting hole 16 at the rear bottom of the insertion rod 2 and the limiting hole 15 at the rear bottom of the sleeve 5. This precisely positions the insertion rod 2 within the sleeve 5, completing the stable connection between the headrest 1 and the chair back 3. When it is necessary to disassemble the headrest 1, the slider 10... The soft pad on the front side applies a backward pushing force to overcome the elastic force of the spring 14, causing the slider 10 to slide backward along the slide groove 9. The extension block 12 moves backward in the limiting groove 11 accordingly, driving the limiting pin 13 to exit from the limiting hole 2 16 and the limiting hole 15. At this time, the insertion rod 2 can be pulled out from the sleeve 5 to realize the disassembly of the headrest 1. During the entire use, the washer 18 at the top of the outer side of the insertion rod 2 buffers the pressure between the headrest 1 and the insertion rod 2, making the connection tight. The sealing rings 17 at the top left and right ends of the chair back 3 prevent dust and other impurities from entering the connection between the insertion rod 2 and the sleeve 5. The fixing rod 6 at the bottom of the outer side of the sleeve 5 enhances the stability of the sleeve 5 in the chair back 3. The front side of the cavity 8 fits against the front side of the inner wall of the chair back 3 to ensure smooth cooperation of all components.
