The following describes the implementation of the present invention based on its overall structure.

[0027] Reference Figure 1 As shown, the embodiment of the present application provides a headrest structure, comprising:

[0028] Main body 1;

[0029] A backrest 2 is mounted on one end of the main body 1, and a bracket 3 is mounted on the side of the backrest 2 away from the main body 1;

[0030] A plurality of first support rods 4 are connected between the bracket 3 and the backrest 2, and both ends of the first support rods 4 are hinged to the bracket 3 and the backrest 2 respectively;

[0031] The bracket 3 is fixedly connected to a connecting portion 5, which includes a first crossbar 51 close to the backrest 2. Both ends of the first crossbar 51 are fixedly connected to vertical rods 52. The two vertical rods 52 pass through the side of the bracket 3 close to the backrest 2 and are fixedly connected.

[0032] A push rod 53 is hingedly connected to the middle of the first crossbar 51 , and a second crossbar 54 is hingedly connected to the end of the push rod 53 away from the first crossbar 51 . Both ends of the second crossbar 54 are connected to second support rods 55 .

[0033] The ends of the two second support rods 55 pass through the first cross bar 51 and are hinged to the backrest 2 , and the push rod 53 enables the two second support rods 55 to slide relative to the first cross bar 51 .

[0034] In the prior art, the bed headrest structure may experience obvious problems such as jamming during adjustment. In the above structure, the first support rod 4 and the second support rod 55 can be used for control to solve the above problems.

[0035] Specifically, the main body 1 can be connected to the backrest 2. Those skilled in the art can connect the main body 1 and the backrest 2 through the bracket 3 and the connecting part 5.

[0036] A bracket 3 is installed on the side of the backrest portion 2 away from the main body portion 1 . It is understandable that the bracket 3 and the backrest portion 2 may not be directly connected.

[0037] In a further configuration, a first support rod 4 is provided on the bracket 3. One end of the first support rod 4 is hinged to the bracket 3, and the other end is hinged to the backrest 2.

[0038] By means of the above structure, the backrest portion 2 and the bracket 3 can be connected via the first support rod 4. That is, the backrest portion 2 and the bracket 3 are connected so as to be relatively movable.

[0039] Furthermore, a connecting portion 5 is provided on the bracket 3. The connecting portion 5 includes a first crossbar 51 and two vertical bars 52 connected to the ends of the first crossbar 51. The two vertical bars 52 extend toward the bracket 3 and pass through the bracket 3. It is worth noting that the two vertical bars 52 are fixedly connected to the bracket 3.

[0040] According to the above structure, a push rod 53 is hinged at the middle position of the first cross bar 51. The push rod 53 extends in a direction away from the first cross bar 51, and the extension direction of the push rod 53 is the same as that of the two vertical rods 52. That is, the push rod 53 extends through the middle position of the bracket. The end of the push rod 53 away from the first cross bar is hinged to a second cross bar 54, and both ends of the second cross bar 54 are fixedly connected to second support rods 55. The two second support rods 55 both extend in the direction of the first cross bar 51 and pass through the first cross bar. According to Figure 1 The extended ends of the two second support rods 55 are hinged to the backrest.

[0041] It is worth noting that in the above arrangement, the first support rod 4 and the two second support rods 55 are hinged to the backrest, wherein the two second support rods 55 and the first crossbar can move relative to each other. Those skilled in the art can drive the two second support rods 55 to move synchronously by moving the push rod.

[0042] During the above process, the push rod can move up and down along the height of the bracket. This movement of the push rod causes the two second support rods 55 to move. The ends of the second support rods 55 hinged to the backrest rotate, driving the backrest to move. During the movement of the backrest, the hinged ends of the first support rod 4 can rotate, thereby supporting the backrest and allowing the backrest to move to a certain position.

[0043] According to the above process, those skilled in the art can adjust the position of the backrest by arranging the first support rod 4 and the second support rod 55. Specifically, the entire backrest can be moved simply by moving the push rod, thereby simplifying the operation of the backrest. In addition, in the above structure, the first support rod 4 and the second support rod 55 are separated from each other and independently connected, thereby making the movement of the backrest smoother.

[0044] In one embodiment, the backrest portion 2 preferably has a working side 21 facing the main body portion 1 and a connecting side 22 opposite the working side 21, and the first support rod 4 and the second support rod 55 are both hingedly connected to the connecting side 22. In other words, those skilled in the art can further configure the backrest portion 2 such that the first support rod 4 and the second support rod 55 are both hingedly connected to the connecting side 22.

[0045] according to Figure 1 The connection side 22 of the backrest 2 faces the bracket 3, while the working side 21 faces the main body 1. This allows both the first support rod 4 and the second support rod 55 to be positioned away from the main body 1 and shielded by the backrest 2. This arrangement of the first and second support rods 4, 55 at the connection side 22 optimizes the spatial arrangement of the headrest structure, ensuring that the operating elements do not interfere with normal use.

[0046] In further setting of the connecting side 22, preferably, the connecting side 22 has a first edge 221 close to the main body 1 and a second edge 222 away from the main body 1, multiple first support rods 4 are hinged between the first edge 221 and the second edge 222, and two second support rods 55 are hinged on the first edge 221.

[0047] With the above structure, the movement of the backrest 2 can be stably restricted by hingedly connecting the first support rod 4 between the first side portion 221 and the second side portion 222. Furthermore, by hingedly connecting the two second support rods 55 to the first side portion 221, the backrest can be accurately controlled during the movement of the second support rods 55.

[0048] In the above embodiment, the two second support rods 55 can move relative to the first crossbar 51. Preferably, linear bearings are provided at the connection between the two second support rods 55 and the first crossbar 51. The provision of the linear bearings can make the relative movement between the two second support rods 55 and the first crossbar 51 smoother. In other words, the provision of the linear bearings can prevent the two second support rods 55 from getting stuck during movement.

[0049] In an optional embodiment, a motor is preferably connected to the end of the push rod 53 near the first cross bar 51. The motor can drive the push rod to move, and the movement of the push rod can drive the movement of the two second support rods 55. In a specific implementation, the motor can cause the push rod to extend or move up and down, thereby enabling the push rod to drive the movement of the second support rods.

[0050] The above structure enables automatic adjustment of the relative position of the backrest 2. Those skilled in the art can configure the motor's startup and operating status to be controlled by a button or remote control. This allows for one-touch adjustment of the backrest 2, or precise remote control of the backrest 2.

[0051] according to Figure 1 Preferably, a fixing rod 6 is connected between the ends of the two second supports 55 hinged on the first side portion 221. The ends of the fixing rod 6 are respectively connected to the two second support rods 55, thereby maintaining a fixed distance between the two second support rods 55. This makes the structure of the two second support rods 55 on the backrest 2 more stable and prevents asynchronous rotation of the hinged portion of the two second support rods 55.

[0052] Furthermore, in this embodiment, a person skilled in the art may provide multiple first support rods 4. Preferably, the multiple first support rods 4 are respectively connected to the two ends and the middle position of the side wall of the bracket 3 facing the backrest. In a specific implementation, a person skilled in the art may provide three first support rods 4, wherein the three first support rods 4 are respectively hinged to the two ends and the middle position of the side wall of the bracket 3 facing the backrest. The aforementioned arrangement can make the connection between the bracket 3 and the backrest more stable, and also make the backrest more stable during movement.

[0053] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0054] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
