[0006] A seat table board with an embedded unlocking mechanism, including an inner table board, a support plate, and an outer table board, and further including an unlocking mechanism. The unlocking mechanism includes an unlocking button housing, an unlocking button, a locking tongue, and a return spring. The unlocking button housing is connected to the outer table board. The unlocking button is arranged inside the unlocking button housing. The locking tongue is slidably arranged on the support plate. Two ends of the return spring are respectively connected to the locking tongue and the inner table board. The unlocking button contacts the locking tongue and can unlock the locking tongue.

[0007] As a preference of the utility model, a sliding bar is arranged on the locking tongue, and a sliding groove is arranged on the support plate, and the sliding bar moves in the sliding groove.

[0008] As a preference of the utility model, an inclined unlocking slideway is arranged on the locking tongue.

[0009] As a preference of the utility model, an unlocking block is arranged at one end of the unlocking button, and an inclined surface is formed on the unlocking block, and the inclined surface is connected to the unlocking slideway.

[0010] As a preference of the utility model, a table board lock hole arranged on the seat back plate is further included.

[0011] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effect of the utility model is:

[0012] 1. A seat table board with an embedded unlocking mechanism according to the present utility model transfers the unlocking mechanism from the seat backrest to the inside of the table board while maintaining the original thickness of the table board, solving the problem that the seat backrest cannot increase the table board and the control screen simultaneously due to insufficient space position.

[0013] 2. A seat table board with an embedded unlocking mechanism according to the present utility model has a small unlocking switch volume. The unlocking mechanism cancels the unlocking cover bracket compared with the traditional structure, reducing the volume of the unlocking mechanism to 1 / 2 of the original, saving the installation space and leaving more space for the seat backrest to add other functional accessories.

[0026] The following further describes the present utility model in detail through specific embodiments in conjunction with the drawings.

[0027] Refer to Figures 1 to 7 , Figure 1 , Figure 2 is a perspective view of the present utility model, Figure 3 is an exploded view of the present utility model, Figure 4 is a perspective view of the table board lock hole of the present utility model, Figure 5 is a perspective view of the unlocking button and the lock tongue of the present utility model, Figure 6 is a perspective view of the lock tongue of the present utility model, Figure 7 is a perspective view of the present utility model applied to the back of a seat. A seat table board with an embedded unlocking mechanism provided by the present utility model includes an inner table board 1, a support board 2, an outer table board 3, an unlocking mechanism 4, and a table board lock hole 5. The inner table board 1, the support board 2, and the outer table board 3 are connected to form a small table board main body and are connected to the seat back through mechanisms such as connecting rods. The support board 2 is arranged between the inner table board 1 and the outer table board 3. The unlocking mechanism 4 is arranged between the inner table board 1 and the outer table board 3 and is connected to the support board 2. The table board lock hole 5 is arranged on the seat back panel. The unlocking mechanism 4 cooperates with the table board lock hole 5 to realize the unlocking and locking of the seat table board.

[0028] The unlocking mechanism 4 includes an unlocking button housing 41, an unlocking button 42, a locking tongue 43, and a return spring 44. The unlocking button housing 41 penetrates through the outer table board 3. The unlocking button housing 41 is preferably snap-connected to the outer table board 3 to ensure stability. The unlocking button 42 is arranged inside the unlocking button housing 41 and can move relying on the unlocking button housing 41. The locking tongue 43 is slidably arranged on the support plate 2. In one embodiment, a slide bar 431 is provided on the locking tongue 43, and a sliding groove 21 is provided on the support plate 2. The slide bar 431 moves in the sliding groove 21. The two ends of the return spring 44 are respectively connected to the locking tongue 43 and the inner table board 1. The unlocking button 42 contacts the locking tongue 43 and can unlock the locking tongue 43, so that the seat table board is unlocked and locked. In one embodiment, an inclined unlocking slideway 432 is provided on the locking tongue 43, and an unlocking block 421 is provided at one end of the unlocking button 42. An inclined surface 4211 is formed on the unlocking block 421. The inclined surface 4211 is connected and contacts the unlocking slideway 432. After pressing the unlocking button 42, the unlocking block 421 moves downward, and the inclined surface 4211 pushes the unlocking slideway 432 to move backward, and the locking tongue 43 disengages from the table board lock hole 5, unlocking the seat table board. After releasing the unlocking button 42, the elastic force of the return spring 44 pushes the locking tongue 43 out, which can be inserted into the table board lock hole 5 to lock the seat table board.

[0029] The working principle of the present utility model will be described below with reference to Figures 1 to 7 this.

[0030] Press the unlocking button 42, and the locking tongue 43 disengages from the table board lock hole 5, unlocking the seat table board. After releasing the unlocking button 42, the locking tongue 43 pops out relying on the elastic force of the return spring 44 and is inserted into the table board lock hole 5 to lock the seat table board. On the basis of retaining the original thickness of the table board, the present utility model transfers the unlocking mechanism from the seat backrest to the inside of the table board, solving the problem that the seat backrest cannot increase the table board and the control screen at the same time due to insufficient space position. At the same time, the unlocking mechanism 4 is small in volume. The unlocking mechanism 4 cancels the unlocking cover bracket compared with the traditional structure, reducing the volume of the unlocking mechanism 4 to 1 / 2 of the original, saving the installation space and leaving more space for the seat backrest to add other functional accessories.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
