[0028] The present utility model will be further described in detail below through specific embodiments in conjunction with the drawings.

[0029] Refer to Figures 1 to 4 , Figure 1 is a perspective view of the present utility model, Figure 2 is an exploded view of the present utility model, Figure 3 is a front view of a part of the structure of the present utility model, Figure 4 is a front view of the unlocking mechanism of the present utility model. A button-unlocking type rear-folding headrest provided by the present utility model includes a housing 1, a guide sleeve 2, an unlocking mechanism 3, a headrest rod 4, a headrest 5, and a folding mechanism 6. The housing 1 includes a front housing 13 and a rear housing 14. The guide sleeve 2 and the unlocking mechanism 3 are arranged inside the housing 1. The unlocking mechanism 3 is used to connect to the seat. The headrest rod 4 is connected to the guide sleeve 2. The headrest 5 is connected to the headrest rod 4. The folding mechanism 6 is arranged at the lower part of the housing 1 and is connected to the seat. The folding mechanism 6 is used to fold the housing 1. In one embodiment, the folding mechanism 6 is provided with a damping (not shown) so that the housing 1 rotates and folds slowly. In another embodiment, the folding mechanism 6 is provided with an angle adjuster (not shown) so that the housing 1 can rotate and fold by a certain angle; when the unlocking mechanism 3 is fixedly connected to the seat, the headrest is in a normal working state. When the unlocking mechanism 3 is disconnected from the seat, the housing 1 with the headrest 5 rotates towards the back of the seat by relying on the folding mechanism 6.

[0030] In one embodiment, the unlocking mechanism 3 includes an unlocking button 31, a locking tongue 32, a locking tongue shield 33, and a spring 34. The spring 34 is used for the reset of the unlocking button 31 and the locking tongue 32. The spring 34 for resetting the locking tongue is preferably arranged inside the locking tongue shield 33. The two ends of the spring 34 are respectively connected to the locking tongue shield 33 and the locking tongue. The two ends of the spring 34 for resetting the unlocking button 31 are respectively connected to the unlocking button 31 and a fulcrum of the housing. Further, the locking tongue 32 includes a first locking tongue 321 and a second locking tongue 322 which are oppositely arranged. Both the first locking tongue 321 and the second locking tongue 322 are provided with inclined portions 323 for facilitating unlocking. The unlocking button 31 is symmetrically provided with unlocking blocks 311. An unlocking inclined surface 3111 is formed on the unlocking block 311. The unlocking inclined surface 3111 is connected to the inclined portion 323. When unlocking, the unlocking button 31 is pressed. The unlocking blocks 311 apply force to the first locking tongue 321 and the second locking tongue 322. The unlocking inclined surface 3111 pushes the inclined portion 323 to move. Then, the first locking tongue 321 and the second locking tongue 322 move in opposite directions, so that the first locking tongue 321 and the second locking tongue 322 release the locking hook (not shown) fixed on the seat, realizing unlocking.

[0031] In one embodiment, the folding mechanism 6 includes a rotating shaft seat 61, a rotating shaft 62, and a rotating shaft spring 63. The rotating shaft seats 61 are symmetrically arranged on both sides below the housing 1. The rotating shaft 62 is arranged on the rotating shaft seat 61. The rotating shaft spring 63 is arranged inside the rotating shaft seat 61 and connected to the rotating shaft 62, that is, one end of the rotating shaft spring 63 abuts inside the rotating shaft seat 61, and the other end is connected to one end of the rotating shaft 62, so as to provide an elastic force for the rotating shaft 62 to extend outwards, enabling a part of the structure of the rotating shaft 62 to be connected to the seat. Finally, the housing 1 can be folded and rotated depending on the rotating shaft 62.

[0032] In one embodiment, a bracket 11 is arranged inside the housing 1. A round tube 12 for installing the guide sleeve 2 is arranged on the bracket 11. At the same time, the unlocking mechanism 3 can also be arranged on the bracket 11.

[0033] The following will refer to Figures 1 to 4 to illustrate the working principle of the present utility model.

[0034] Press the unlocking button 31, the locking tongue 32 pops open, releasing the locking hook arranged on the seat back. The housing 1 rotates depending on the folding mechanism 6, driving the headrest 5 to rotate and fold to the back of the seat. This unique rear folding form can make more reasonable use of the space on the back of the seat, realizing the seat into a bed mode, which can be applied to more shaped seats and is suitable for the current trend of new energy vehicles requiring more comfort, more portability, and more intelligence.

[0035] The above are only the specific embodiments 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 conceive 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 shall be subject to the protection scope of the claims.
