[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figure 1-4 As shown, an unlocking structure for a car seat table includes a mounting base 1, an unlocking button 2 that is slidably connected to the front of the mounting base 1 in a Y-direction, a locking hook 3 that is slidably connected to the front of the mounting base 1 in a Z-direction and obliquely slidably engaged with the unlocking button 2, a Y-direction return spring 4 sandwiched between the mounting base 1 and the unlocking button 2, and a Z-direction return spring 5 sandwiched between the mounting base 1 and the locking hook 3. The top of the mounting base 1 is recessed with a limiting groove 6, and the top of the mounting base 1 has a clearance through hole 7 adjacent to the limiting groove 6. The front of the mounting base 1 has a Z-guide rail 8 that protrudes along the bottom of the front of the mounting base 1, passes through the clearance through hole 7, and extends to the top of the front of the mounting base 1. The back of the locking hook 3 has a Z-guide groove 9 that slidably engages with the Z-guide rail 8. The locking hook 3 is used to lock the car seat table. When the unlocking button 2 is pressed, the locking hook 3 moves upward along the Z-guide rail 8 and passes through the clearance through hole 7.

[0019] The unlocking structure of this car seat table is applied to the back of the car seat and locks the table installed on the back of the car seat. When the unlocking button 2 is pressed, the locking hook 3 moves up along the Z-guide rail 8 and passes through the clearance through hole 7, providing more Z-direction movement space for the locking hook 3, avoiding the locking hook 3 from colliding with the mounting base 1 and restricting the unlocking of the locking hook 3, and at the same time avoiding the risk of the locking hook 3 cracking and failing due to the collision.

[0020] Furthermore, the bottom wall of the limiting groove 6 is provided with a first locking hole 10, and the locking hook 3 extends with a first long arm buckle 11. The first long arm buckle 11 moves through the first locking hole 10 and is limited and engaged with the first locking hole 10, so as to ensure that the locking hook 3 moves along the Z guide rail 8 while preventing the locking hook 3 from falling off the mounting base 1.

[0021] Furthermore, the locking hook 3 includes a guide sliding part 31, a guide inclined support part 32, and a locking tongue part 33 connected in sequence. The Z-guide groove 9 is opened on the back of the guide sliding part 31. The first long arm buckle 11 extends between the guide sliding part 31 and the guide inclined support part 32. An avoidance step 12 for avoiding the unlocking button 2 is opened between the guide inclined support part 32 and the locking tongue part 33. An avoidance groove 13 for cooperating with the avoidance step 12 to avoid collision between the bottom of the unlocking button 2 and the locking hook 3 when the locking hook 3 moves upward along the Z-guide rail 8 after the unlocking button 2 is pressed.

[0022] Furthermore, hollow triangular guide platforms 14 protrude from both sides of the guide sliding part 31. The side of the hollow triangular guide platform 14 near the locking tongue part 33 is inclined backward. Two push feet 15 protrude from the back of the unlocking button 2. The ends of the push feet 15 are inclined backward. The side of the hollow triangular guide platform 14 near the locking tongue part 33 slides against the end face of the push feet 15. The use of hollow triangular guide platforms 14 is more conducive to avoiding empty space during injection molding, which can easily lead to breakage during use. In addition, the hollow triangular guide platform 14 and the push feet 15 have a surface-to-surface contact, with a larger contact area, which is more conducive to improving the stable guiding effect.

[0023] Furthermore, the end corner of the push foot 15 is rounded to provide more clearance and prevent the end of the push foot 15 from colliding with the mounting base 1 and breaking easily when the unlock button 2 is pressed.

[0024] Furthermore, the guide inclined support 32 has a first reinforcing rib 16 in the middle, which helps to improve the support strength of the guide inclined support 32 and prevent the guide inclined support 32 from breaking easily during use.

[0025] Furthermore, the guide sliding part 31 is provided with a first spring positioning post 17, and the bottom of the limiting groove 6 is provided with a second spring positioning post 18. The first spring positioning post 17 and the second spring positioning post 18 are respectively inserted into the two ends of the Z-direction reset spring 5, which facilitates the assembly and positioning of the Z-direction reset spring 5 and prevents the Z-direction reset spring 5 from easily becoming displaced during use.

[0026] Furthermore, the front of the mounting base 1 is recessed with a button limiting groove 19, and the two inner sides of the button limiting groove 19 are provided with snap-fit ​​guide grooves 20. The mounting base 1 is provided with a second snap hole 21 communicating with the snap-fit ​​guide grooves 20. The back of the unlock button 2 extends with a second long-arm snap 22, which moves along the snap-fit ​​guide groove 20 through the second snap hole 21 and is limited and engaged with the second snap hole 21. This ensures that the unlock button 2 moves along the snap-fit ​​guide groove 20 while preventing the unlock button 2 from detaching from the mounting base 1.

[0027] Furthermore, the front of the mounting base 1 is provided with a third spring positioning post 23, and the back of the unlock button 2 is provided with a fourth spring positioning post 24. The third spring positioning post 23 and the fourth spring positioning post 24 are respectively inserted into the two ends of the Y-direction reset spring 4, which facilitates the assembly and positioning of the Y-direction reset spring 4 and prevents the Y-direction reset spring 4 from easily becoming displaced during use.

[0028] Furthermore, the back of the mounting base 1 has multiple intersecting second reinforcing ribs 25, which helps to improve the support strength of the mounting base 1.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
