Description

Technical Field

[0001] This utility model relates to the technical field of car seat tray tables, specifically to an unlocking structure for a car seat tray table. Background Technology

[0002] A car seat tray table is a component installed behind the front seats of a car. It can be used to place food, laptops, etc., and can be folded away for storage when not in use. Most existing tray tables consist of a front panel and a back panel assembled together, hinged to the seat back using a linkage. Furthermore, traditional tray tables have their locking assembly and unlocking button integrated into the seat back; the locking assembly locks the tray table in place, and pressing the unlocking button releases the lock.

[0003] With the improvement of living standards, there is a need to install components such as displays on the back of seats, which conflict with the space required for unlocking buttons. To address this issue, existing applications (application number 202421846897.5) describe a table structure and car seat with an unlocking mechanism. When the small table assembly needs to be unlocked, the user pulls the unlocking lever, which rotates relative to the unlocking base. This rotation compresses a return torsion spring (the lever automatically returns to its original position when released). The lever's rotation also moves an unlocking push rod within the latch slot, pushing the latch out (compressing the latch return spring when the latch moves away from the slot, allowing the latch to return to its original position), thus unlocking the small table assembly. However, the convenience of lever-based unlocking is inferior to that of traditional button-based unlocking. Summary of the Invention

[0024] 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.

[0025] like Figure 1-8 As shown, an unlocking structure for a small table on a seat is provided. The small table 7 is hinged to the back of the seat and locked to the back of the seat by a locking assembly 8. The locking assembly 8 is fixedly connected to the back of the seat. The unlocking structure includes an unlocking base 1 fixedly housed within the small table 7, an unlocking slider 2 slidably disposed on the unlocking base 1, an unlocking latch 3 hinged to the top of the unlocking slider 2, an unlocking button 4 pressable on the back of the small table 7 and extending into the unlocking base 1, a guide shaft 5 fixed to the unlocking slider 2, passing through the unlocking button 4 and extending out of the unlocking base 1, and a first reset elastic member 6 sandwiched between the unlocking button 4 and the unlocking base 1. The top of the small table 7 has a locking opening 9 for locking with the locking assembly 8, and the unlocking latch 3 extends into the locking opening 9.

[0026] This unlocking mechanism is separated from the traditional latch assembly. The latch assembly 8 is fixedly connected to the back of the seat, and the unlocking mechanism is installed on the small table 7. When the unlocking button 4 is pressed to unlock, the unlocking button 4, the guide shaft 5, and the unlocking slider 2 sequentially drive the unlocking tongue 3 to push the latch assembly 8 out of the lock opening 9, thereby releasing the latch assembly 8 from the lock opening 9. This provides greater convenience and better meets user needs.

[0027] Furthermore, the unlocking base 1 has a longitudinal guide hole 10 on its side wall and a clearance groove 11 in the middle of its center. The unlocking button 4 extends into the clearance groove 11 with a guide plate 12. The guide plate 12 has an oblique guide hole 13 that is inclined from bottom to top along the end face near the unlocking button 4 and communicates with the longitudinal guide hole 10. The guide shaft 5 passes through the oblique guide hole 13 and the longitudinal guide hole 10 in sequence. When the unlocking button 4 is pressed to unlock, the unlocking button 4 moves toward the unlocking base 1. The unlocking button 4 drives the guide shaft 5 to move from below the oblique guide hole 13 to above the oblique guide hole 13 and from below the longitudinal guide hole 10 to above the longitudinal guide hole 10. The guide shaft 5 drives the unlocking slider 2 to move upward. The unlocking slider 2 drives the unlocking latch 3 to push the latch assembly 8 out of the lock opening 9. When the unlock button 4 is released, the first reset elastic element 6 resets the unlock button 4. At the same time, under the cooperation of the guide shaft 5, the oblique guide hole 13 and the longitudinal guide hole 10, the unlock slider 2 and the unlocking latch 3 are reset, and the unlock button 4 is prevented from detaching from the unlock base 1 from the small table 7.

[0028] Furthermore, the unlocking base 1 is provided with a longitudinal groove 14, and the unlocking slider 2 is slidably disposed in the longitudinal groove 14.

[0029] Furthermore, the lock opening 9 is inclined, and the top of the unlocking slider 2 is provided with a horizontal guide hole 15. The unlocking bolt 3 is hinged to the unlocking slider 2 through the horizontal guide hole 15 so that the unlocking bolt 3 can push the latch assembly 8 in the inclined lock opening 9.

[0030] Furthermore, the small table 7 includes a back panel 71, a panel 72 covering the back panel 71, a reinforcing frame 73 sandwiched between the back panel 71 and the panel 72 and fixedly connected to the panel 72, and an encapsulation strip 74 sandwiched between the edge of the back panel 71 and the edge of the panel 72, wherein the locking slot 9 is opened at the top of the encapsulation strip 74.

[0031] Furthermore, a first limiting boss 16 protrudes from the bottom of the end of the lock opening 9 away from the unlocking base 1, and a second limiting boss 17 protrudes from the bottom of the end of the unlocking bolt 3 near the unlocking slider 2. The first limiting boss 16 and the second limiting boss 17 work together to limit the unlocking bolt 3, preventing the unlocking bolt 3 from protruding from the lock opening 9 when it pushes out of the latch assembly 8.

[0032] Furthermore, the back plate 71 has a recess 18 for exposing the end face of the unlock button 4 to the back plate 71, so that the user can press the unlock button 4 on the back plate 71.

[0033] Furthermore, the locking assembly 8 includes a lock seat 81 fixedly connected to the back of the seat, a lock tongue 82 slidably disposed on the lock seat 81, and a second reset elastic member 83 sandwiched between the lock tongue 82 and the lock seat 81. When the locking assembly 8 locks the small table 7, the bottom end of the lock tongue 82 engages with the lock opening 9. Preferably, both the first reset elastic member 6 and the second reset elastic member 83 are compression springs.

[0034] Furthermore, a limiting groove 19 is provided on one side of the latch tongue 82, and a limiting hook 20 is provided on one side of the lock seat 81 that is bent toward the limiting groove 19. The limiting hook 20 cooperates with the limiting groove 19 to limit the latch tongue 82, so as to prevent the second reset elastic member 83 from pushing the latch tongue 82 out and disengaging from the lock seat 81.

[0035] 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.
