[0027] Specific implementation examples:
[0028] As shown in Figures 1-4, this application provides a car seat slide rail with an anti-accidental-touch locking structure, including a control lever 1. Slide rail assemblies 2 are provided at both ends of the control lever 1. Each slide rail assembly 2 includes a guide rail 21 and a sliding rail 22 movably disposed within the guide rail 21. A locking assembly 3 and a linkage reset assembly 4 for connecting to the end of the control lever 1 are provided between the guide rail 21 and the sliding rail 22. The locking assembly 3 engages with the sliding rail 22 and the guide rail 21. The locking assembly 3 can disengage from the guide rail 21 through the cooperation of the control lever 1 and the linkage reset assembly 4. An anti-accidental-touch component 5 is provided on the sliding rail 22 to prevent accidental-touch of the locking assembly 3. Under normal conditions, the locking assembly 3 and the sliding rail... 22. The guide rail 21 engages, allowing the sliding rail 22 to be stably fixed in a specific position within the guide rail 21, preventing the seat from sliding arbitrarily. When the seat position needs to be adjusted, the control lever 1 is operated. The end of the control lever 1 cooperates with the linkage reset component 4, causing the locking component 3 to disengage from the guide rail 21. At this time, the sliding rail 22 can slide freely within the guide rail 21, thereby realizing the adjustment of the seat position. The anti-accidental contact component 5 prevents the locking component 3 from accidentally disengaging from the guide rail 21 when the seat position is adjusted without human intervention by operating the control lever 1. This avoids the seat from suddenly sliding due to accidental contact, ensuring the stability and safety of the seat during normal use.
[0029] As shown in Figure 2-4, the locking assembly 3 includes a locking seat 31, a locking pin 32, a locking member 33, and a spring 34. The locking seat 31 has a limiting through hole 311. The lower end of the locking pin 32 passes through the limiting through hole 311 and is connected to the locking member 33. The locking pin 32 has a first annular limiting part 321 located inside the limiting through hole 311. The inner bottom of the limiting through hole 311 has a second annular limiting part 312. The spring 34 is sleeved on the locking pin 32 and located on the first annular limiting part. Between 321 and the second annular limiting part 312, the sliding rail 22 is provided with a locking hole 221. The upper end of the locking pin 32 can pass through the locking hole 221. Under normal circumstances, the spring 34 is in a compressed state, and the elastic force generated by it pushes the first annular limiting part 321, thereby causing the locking pin 32 to move upward. Since the lower end of the locking pin 32 is connected to the engaging part 33, it can prevent the locking pin 32 from disengaging from the limiting through hole 311. In the initial state, the upper end of the locking pin 32 is inserted into the locking hole 221.
[0030] As shown in Figures 1-4, the anti-accidental contact component 5 includes a protective member 51 and two locking screws 52. The two locking screws 52 allow the protective member 51 to be installed on the locking seat 31, positioning it above the sliding rail 22. The protective member 51 has a clearance portion 511 for the upper end of the locking pin 32. Under normal conditions, the upper end of the locking pin 32 is within this clearance portion 511. Due to the obstruction of the protective member 51, accidental contact with the locking pin 32 is prevented, thus avoiding accidental downward movement of the locking pin 32 and preventing the locking component 3 from unlocking. This ensures that the sliding rail 22 is stably locked within the guide rail 21, and unlocking is only possible when the control lever is manually operated. When the linkage reset component 4 is driven, the locking pin 32 moves downward and disengages from the relief part 511, the sliding rail 22 will be unlocked. This effectively prevents the sliding rail 22 from moving accidentally due to accidental contact, thus preventing the seat from sliding unexpectedly. Specifically, the locking seat 31 is provided with a threaded hole 7 that matches the locking screw 52. Both the protective part 51 and the sliding rail 22 are provided with mounting holes 8 corresponding to the threaded hole 7. By passing the locking screw 52 through the mounting hole 8 on the protective part 51 and the mounting hole 8 on the sliding rail 22 in sequence, and then screwing it into the threaded hole 7, the protective part 51 can be fixed to the upper part of the sliding rail 22 and the locking seat 31 can be fixed to the lower part of the sliding rail 22.
[0031] As shown in Figures 2 and 4, the locking seat 31 is provided with a positioning post 313, and both the protective component 51 and the sliding rail 22 are provided with positioning holes 6 that are adapted to the positioning post 313. The positioning post 313 is located in the positioning hole 6. During the installation process, the positioning post 313 can be accurately inserted into the positioning hole 6, providing precise guidance for the installation of the protective component 51 and the sliding rail 22, and ensuring that the protective component 51 and the locking seat 31 are accurately positioned on the sliding rail 22.
[0032] As shown in Figures 3 and 4, the engaging component 33 is provided with engaging teeth 331, the sliding rail 22 is provided with engaging holes 222 that are adapted to the engaging teeth 331, and the guide rail 21 is provided with a plurality of engaging grooves 211 that are adapted to the engaging teeth 331 evenly along the guiding direction. The engaging teeth 331 penetrate the engaging holes 222 and the engaging grooves 211. In the initial state, the engaging teeth 331 on the engaging component 33 are tightly engaged with the engaging holes 222 on the sliding rail 22 and the engaging grooves 211 on the guide rail 21. When the seat position needs to be adjusted, the operating control lever 1 drives the linkage reset component 4, which in turn acts on the locking component 3. The action of the locking component 3 will cause the engaging component 33 to shift, and the engaging teeth 331 will disengage from the currently embedded engaging groove 211 and move downward away from the engaging holes 222 of the sliding rail 22, while the engaging teeth 331 remain in the engaging holes 222.
[0033] As shown in Figures 2 and 4, the linkage reset assembly 4 includes a linkage member 41 and a torsion spring 42. One end of the linkage member 41 is connected to the end of the control lever 1, and the other end of the linkage member 41 is provided with a linkage part 411. The linkage part 411 abuts against the top of the engaging member 33 and is slidably connected to the locking seat 31. The linkage member 41 is connected to the sliding rail 22 through the torsion spring 42. Specifically, the sliding rail 22 is provided with a connecting ear 9 for connecting with a car seat, the linkage member 41 is provided with a connecting hole 10, and a fitting adapted to the connecting hole 10 is fixed on the sliding rail 22. The connecting post (not shown in the figure) is movably disposed within the connecting hole 10. The linkage 41 is rotatably connected to the slide rail 22 through the cooperation between the connecting hole 10 and the connecting post. The torsion spring 42 is disposed between the linkage 41 and the slide rail 22. When the seat is in the locked position, the torsion spring 42 maintains the relative position between the linkage 41 and the slide rail 22. When the seat position needs to be adjusted and the control lever 1 is operated, the control lever 1 is pulled upward. The end of the control lever 1 drives the linkage 41 to rotate around its connection point with the slide rail 22. Due to the linkage 411 and The top of the engaging member 33 abuts against and slides with the locking seat 31. Rotation of the linkage member 41 causes the linkage part 411 to push the engaging member 33 downwards. As the engaging member 33 moves downwards, the engaging teeth 331 gradually disengage from the engaging groove 211 of the guide rail 21. During this process, the torsion spring 42 and the spring 34 deform and store elastic potential energy. At this time, the sliding rail 22 can slide freely within the guide rail 21, thereby adjusting the seat position. When the seat is adjusted to the appropriate position, the control lever 1 is released. At this time, the torsion spring 42 begins to release the stored elastic potential energy. The elastic potential energy and the elastic force of the torsion spring 42 act on the linkage 41, causing the linkage 41 to rotate in the opposite direction around the connection point. The reverse rotation of the linkage 41 drives the linkage part 411 to move upward. At the same time, the spring 34 begins to release the stored elastic potential energy. The elastic force of the spring 34 acts on the first annular limiting part 321, which in turn pushes the locking pin 32 to move upward. The locking pin 32 drives the engaging part 33 to move upward, so that the engaging teeth 331 on the engaging part 33 find and engage in the corresponding engaging groove 211 on the guide rail 21, thus completing the locking of the seat in the new position.
[0034] As shown in Figures 2 and 4, the linkage 41 is provided with a receiving groove 412, and the torsion spring 42 is located in the receiving groove 412. The design of the receiving groove 412 cleverly utilizes the structural space of the linkage 41 itself, eliminating the need to open up additional space in the seat slide rail system to install the torsion spring 42, making the structure of the entire seat slide rail more compact.
[0035] Working principle:
[0036] Initial locking state: In the locking assembly 3, the spring 34 pushes the locking pin 32 upward, so that the engaging teeth 331 on the engaging member 33 are embedded in the engaging groove 211 of the guide rail 21. At the same time, the upper end of the locking pin 32 is inserted into the locking hole 221 of the sliding rail 22, fixing the sliding rail 22 in the guide rail 21. The seat cannot move. The protective member 51 of the anti-accidental contact assembly 5 prevents external objects from contacting the locking pin 32. The torsion spring 42 of the linkage reset assembly 4 maintains the relative position of the linkage member 41 and the sliding rail 22, ensuring the stability of the overall structure.
[0037] Unlocking process: Pull the control lever 1 upwards. The end of the control lever 1 drives the linkage 41 to rotate around the connection point with the sliding rail 22. The linkage 411 pushes the engaging part 33 downwards, causing the engaging teeth 331 to disengage from the engaging groove 211. At the same time, the locking pin 32 moves downwards and disengages from the locking hole 221. The sliding rail 22 is unlocked and can slide freely in the guide rail 21. During this process, the torsion spring 42 and the spring 34 deform and store elastic potential energy.
[0038] Seat adjustment: The sliding rail 22 slides within the guide rail 21 to adjust the seat position.
[0039] Relocking process: After the seat is adjusted to the correct position, release the control lever 1. The torsion spring 42 releases its elastic potential energy, causing the linkage 41 to rotate in the opposite direction. The linkage part 411 moves upward. At the same time, the spring 34 releases its elastic potential energy to push the locking pin 32 upward, causing the engaging part 33 to move upward. The engaging teeth 331 re-engage with the corresponding engaging groove 211 of the guide rail 21, thus completing the locking of the seat in the new position.
[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
