[0002] Currently, car seat tray table unlocking typically employs a complex mechanical structure with a hidden lever, which presents several problems. On the one hand, the complex mechanical components are prone to wear or jamming due to long-term use, leading to unsmooth unlocking or even failure. On the other hand, some unlocking devices are hidden in location, making it difficult for passengers to quickly find the unlocking position, especially in emergencies or in low light. In addition, existing unlocking devices lack effective protection for components, making them susceptible to corrosion from dust and debris inside the car, shortening their service life and affecting the normal function of the seat tray table. Utility Model Content

[0003] The purpose of this invention is to provide a button lock for unlocking car seats to solve the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a button latch for unlocking a car seat, comprising a button base, an unlocking component, and a reset component;

[0005] Wherein: the button base has an internal mounting cavity, and the button base has a through hole starting from the middle of its surface, the through hole communicating with the mounting cavity;

[0006] The unlocking component includes a button bracket and a button latch. The button bracket is installed inside the mounting cavity, and the button latch is installed inside the mounting cavity and located in the middle of the button bracket. One end of the button latch passes through a through hole and extends to the outside of the button base. The bottom of the button bracket has a beveled design, and contact bosses are connected to both sides of the button latch. The contact bosses have corresponding beveled designs, and the bottom of the button bracket is in contact with the contact bosses.

[0007] The reset assembly includes limiting holes that extend through both sides of the bottom of the mounting cavity. Limiting posts are connected to both sides of the button bracket. The limiting posts are slidably installed inside the limiting holes. Unlocking reset springs are sleeved on the surface of the limiting posts. Locking tongue reset springs are installed inside the button locking tongue.

[0008] As a preferred embodiment of this utility model: the edge of the button base is fixedly mounted with a support foot, and the surface of the support foot is provided with a mounting hole.

[0009] As a preferred embodiment of this utility model, a fixing screw is installed at the bottom of the limiting post.

[0010] As a preferred embodiment of this utility model: a button trim strip is installed on the top of the button base, and the button trim strip is arranged around the outer ring of the button bracket.

[0011] As a preferred embodiment of this utility model: the button trim is connected to the surrounding area with connecting pieces, the surface of the connecting pieces is provided with positioning holes, and the edges of the button base are equipped with claws, which engage inside the positioning holes.

[0012] As a preferred embodiment of this utility model, the top edge of the button base is surrounded by reinforcing ribs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When it is necessary to unlock the car seat tray, press the button bracket to move it into the mounting cavity. The button bracket moves and contacts the contact bosses on both sides of the button latch through the beveled surface at the bottom. Since the contact surfaces of the button bracket and the contact bosses are designed with corresponding beveled surfaces, the button bracket drives the button latch to retract into the mounting cavity inside the button base through the contact bosses, thereby separating the button latch from the fixed bracket under the tray and completing the unlocking. This unlocking structure is simple and has fewer components, reducing the failure points caused by complex mechanical structures, reducing the risk of damage, and improving the reliability of unlocking. The button is installed in a conspicuous position on the side of the tray, which passengers can easily find and operate without having to fumble in the dark or spend too much time looking for the unlocking device, greatly improving the convenience of use.

[0015] (2) Through the provided reset component, limit holes are opened through both sides of the bottom of the mounting cavity. The limit pins connected to both sides of the button bracket slide through the limit holes. When the button bracket is pressed down to unlock, the limit pin slides inside the limit hole and compresses the unlocking reset spring. At the same time, when the button bracket drives the button lock tongue to retract, it compresses the lock tongue reset spring. When the button bracket is released, the unlocking reset spring restores its deformation and pushes the button bracket to reset. At the same time, the lock tongue reset spring pushes the button lock tongue to extend outward from the through hole and hook onto the fixed bracket to achieve locking. No additional operation is required, and the operation process is simple and convenient. Attached Figure Description

[0026] In practical use: Limiting holes 51 are provided on both sides of the bottom of the mounting cavity 2. Limiting posts 52 connected to both sides of the button bracket 41 slide through the limiting holes 51. When the button bracket 41 is pressed down to unlock, the limiting posts 52 slide inside the limiting holes 51 and compress the unlocking reset spring 53. At the same time, when the button bracket 41 drives the button latch 42 to retract, it compresses the latch reset spring 54. When the button bracket 41 is released, the unlocking reset spring 53 restores its deformation and pushes the button bracket 41 to reset. At the same time, the latch reset spring 54 pushes the button latch 42 to extend outward from the through hole 3 and hook onto the fixed bracket to achieve locking. No additional operation is required, and the operation process is simple and convenient.

[0027] Please see Figure 1 , Figure 2 The edge of the button base 1 is fixedly mounted with a support leg 6, and the surface of the support leg 6 is provided with a mounting hole 7.

Connecting pieces 10 are connected around the button trim 9. Positioning holes 11 are opened on the surface of the connecting pieces 10. When the button trim 9 is installed on the top of the button base 1, the claws 12 engage with the positioning holes 11, so that the button trim 9 is installed on the top of the button base 1.

[0033] Please see Figure 2 The top edge of the button base 1 is surrounded by reinforcing ribs 13.

[0034] In practical use: The reinforcing ribs 13 on the top edge of the button base 1 improve the structural strength of the button base 1. All the components of the unlock button are exposed to the outside, which facilitates daily cleaning and maintenance, effectively avoids the accumulation of dust and debris affecting normal use, and further improves the service life and reliability of the seat table.

[0035] When the car seat tray needs to be unlocked, the button bracket 41 is pressed and moved into the mounting cavity 2. The button bracket 41 moves and contacts the contact protrusions 43 on both sides of the button latch 42 through the beveled surface at the bottom. Since the contact surfaces of the button bracket 41 and the contact protrusions 43 are designed with corresponding beveled surfaces, the button bracket 41 drives the button latch 42 to retract into the mounting cavity 2 inside the button base 1 through the contact protrusions 43. This causes the button latch 42 to separate from the fixed bracket under the tray table, completing the unlocking. This unlocking structure is simple and has fewer components, reducing the failure points caused by complex mechanical structures, lowering the risk of damage, and improving the reliability of unlocking. The button is installed in a conspicuous position on the side of the tray table, which passengers can easily find and operate without having to fumble in the dark or spend too much time looking for the unlocking device, greatly improving the convenience of use.
