Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 4, a headrest includes a headrest body 100, a first flexible support 110, a supporter 120, and a first adjustment unit; the first flexible support 110 is disposed inside the headrest body 100; the supporting member 120 is disposed inside the first flexible supporting member 110, an end of the supporting member 120 abuts against an inner wall of the first flexible supporting member 110, and the supporting member 120 is rotatable relative to the first flexible supporting member 110; the softness of the side of the first flexible support 110 abutting against the support 120 is lower than the softness of the side of the first flexible support 110 not abutting against the support 120; the first adjusting unit is used for adjusting the supporting member 120 so as to rotate the supporting member 120 relative to the first flexible supporting body 110.
In some embodiments, the first flexible supporting body 110 may be made of plastic, and the first flexible supporting body 110 can restore its shape after being deformed, and the first flexible supporting body 110 may be made of plastic to reduce the weight of the headrest body 100, so that the weight of the headrest body 100 is light.
In use, if a user needs a softer headrest body 100, referring to fig. 1 and 2, the first adjustment unit is operated to rotate the support member 120, when the support member 120 rotates to a direction parallel to the head of the human body, the extrusion force of the first flexible support member 110 in a direction perpendicular to the head of the human body disappears, and the foaming space of the headrest body 100 is released, thereby improving the softness of the headrest body 100; if the user needs the headrest body 100 to be hard, referring to fig. 2 and 4 of fig. 1, the first adjustment unit is operated such that the support member 120 rotates, and when the support member 120 rotates to a direction perpendicular to the head of the human body, the support member 120 abuts against the first flexible support member 110, and the first flexible support member 110 presses the sponge of the headrest body 100 close to the head of the human body, thereby increasing the hardness of the headrest body 100.
In the above operation process, the softness and hardness of the headrest body 100 in different directions of the first flexible support 110 are changed by changing the position of the support 120 in the first flexible support 110, so that the requirements of different consumers on the softness and hardness of the headrest body 100 in different scenes are met. For example, when driving, the head of a human body can be protected by making the headrest body 100 hard, and when resting, the spine of the human body can be protected by making the headrest body 100 soft, so that the adaptability is strong.
Based on the above headrest softness and hardness adjusting device, the present application provides the following examples of specific embodiments, which can be arbitrarily combined to form a new headrest body 100 without conflicting with each other. It should be understood that any combination of the examples to form the headrest body 100 is within the scope of the present application.

Therefore, in this embodiment, no matter which direction the first flexible support 110 is subjected to, the relative position between the support 120 and the first flexible support 110 is not changed, and the softness of the headrest body 100 is not affected by external pressure (the softness of the headrest body 100 refers to the softness of the headrest body 100 relative to the head of the human body), so as to improve the stability of the headrest body 100 after the softness adjustment.
For example, referring to fig. 3 and 4, the supporting member 120 includes a transverse shaft, the first flexible supporting member 110 may be an annular first flexible ring, the one-way teeth 111 are circumferentially disposed on an inner wall of the first flexible ring, both ends of the transverse shaft are engaged with the one-way teeth 111 on the inner wall of the first flexible ring, and the first flexible ring is deformed into an oval shape under an interference supporting action of the transverse shaft.
In this embodiment, in order to minimize the hardness of the head of the person when the head rests on the headrest body 100, the support 120 may be a horizontal shaft, and the horizontal shaft may occupy a smaller space of the first flexible support 110, so that the first flexible support 110 is deformed more and the headrest body 100 is more flexible under the action of external force.

And in order to improve the rotational stability of the first rotating rod 130, the first rotating rod 130 is rotatably disposed at both ends or one end of the door bracket 140.
Or, for example, referring to fig. 6, the first flexible supporting body 110 may also be a flexible cylinder with a hollow interior, and the flexible cylinder is surrounded by two bottom surfaces 110-1 parallel to each other and a curved surface 110-2 connecting the two bottom surfaces 110-1; referring to fig. 7, the one-way teeth 111 are circumferentially disposed on the inner wall of the curved surface 110-2, both ends of the transverse shaft are engaged with the one-way teeth 111 on the curved surface 110-2, and the bottom surface 110-1 is deformed into an oval shape under the interference support of the transverse shaft.
When the horizontal shaft rotates, the shape of the cross section of the whole curved surface 110-2 in all directions is changed, and then the sponge in the headrest body 100 is extruded, so that the softness and hardness of the headrest body 100 are changed. In this process, the two bottom surfaces 110-1 correspond to the cross-section of the curved surface 110-2.
In addition, the first adjusting unit includes a first rotating rod 130, one end of the first rotating rod 130 is vertically connected with the middle of the transverse shaft, and the other end of the first rotating rod 130 penetrates through the bottom surface 110-1 and extends to the outside of the headrest body 100.
Referring to fig. 8, a headrest includes a headrest body 100, a second flexible support 210, and a second adjustment unit; the second flexible supports 210 are arranged inside the headrest body 100, different sides of the second flexible supports 210 have different degrees of flexibility, and the second flexible supports 210 can rotate relative to the headrest body 100; the second adjustment unit is used to adjust the second flexible support 210 so that the second flexible support 210 rotates relative to the headrest body 100.
