The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0031] The following description refers to the accompanying drawings, wherein Figures 1-3A headrest assembly 100 according to a first embodiment of the present application is described.

[0032] As shown in the drawings, the headrest assembly 100 according to the first embodiment of the present application comprises a headrest 10, a support rod 20, a mounting member 30, a locking member 40, an unlocking member 50 and a reset member 60. Figures 1-3 Specifically, the headrest 10 is connected with the support rod 20, the support rod 20 extends along a first direction, a plurality of fixing holes 21 are formed on the support rod 20 and are arranged at intervals in the first direction, the mounting member 30 is used for being connected with a seat body, the support rod 20 is movably arranged on the mounting member 30 along the first direction, the locking member 40 is arranged on the mounting member 30 and is movable between a first position and a second position, in the first position, the locking member 40 extends into the fixing hole 21 so as to lock the support rod 20 on the mounting member 30, in the second position, the locking member 40 is out of the fixing hole 21 so as to unlock the support rod 20, the unlocking member 50 and the reset member 60 are both arranged on the mounting member 30, the unlocking member 50 is suitable for driving the locking member 40 to move from the first position to the second position, and the reset member 60 is configured to apply a force to the locking member 40 in a direction from the second position to the first position.

[0033] After the headrest assembly 100 is installed on the seat, the mounting member 30 is connected with the seat body, and the first direction is an up-down direction. In the process of use by a user, when the user needs to adjust the height of the headrest 10, the locking member 40 is driven by the unlocking member 50 to move from the first position to the second position, and then the position of the support rod 20 relative to the mounting member 30 is adjusted up and down, so that the headrest 10 is adjusted to a suitable height, and then the driving of the locking member 40 by the unlocking member 50 is released, and under the action of the force of the reset member 60, the locking member 40 moves from the second position to the first position and extends into the fixing hole 21, so that the locking member 40 can abut against the inner wall of the fixing hole 21, and the displacement of the support rod 20 in the up-down direction is prevented, so that the headrest 10 is locked in the adjusted position, thereby realizing the adjustment of the height of the headrest 10.

[0034] It can be understood that the reset member 60 applies the force to the locking member 40 in the direction from the second position to the first position, when the locking member 40 is located at the first position, the reset member 60 can fix the locking member 40 in the fixing hole 21, and the contact area between the locking member 40 and the inner wall of the fixing hole 21 is relatively large, so that the locking member 40 is not easy to be out of the fixing hole 21, and thus the reliability of the locking of the support rod 20 on the seat is relatively high, thereby the reliability of the locking of the headrest 10 on the seat can be improved.

[0035]

[0036] ​The locking member 40 has low precision requirement for matching with the fixing hole 21, and the locking member 40 is more easily extended into the fixing hole 21 during the process of adjusting the height of the headrest 10, so that the difficulty of adjusting the height of the headrest 10 can be reduced. In addition, during the adjustment, the user can operate the unlocking member 50 to unlock the support rod 20, and the reset member 60 can drive the locking member 40 to automatically lock by applying a force to the locking member 40, so that the difficulty of adjusting the height of the headrest 10 can be further reduced.

[0037] According to the headrest assembly 100 in the first aspect of the present application, the height of the headrest 10 on the seat can be adjusted, and the reliability of the locking of the headrest 10 on the seat is high.

[0038] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The mounting member 30 is formed with a limiting hole 31 penetrating through the mounting member 30 along the first direction, and the support rod 20 is arranged in the limiting hole 31.

[0039] When the support rod 20 is mounted on the mounting member 30, the limiting hole 31 can quickly position the support rod 20, so as to reduce the assembly difficulty of the headrest assembly 100. During the process of adjusting the height of the headrest 10, the limiting hole 31 can guide and limit the movement of the support rod 20 along the up-down direction, so as to reduce the difficulty of adjusting the height of the headrest 10. After the support rod 20 is locked on the mounting member 30, the inner wall of the limiting hole 31 can provide support for the support rod 20, so as to further improve the reliability of the locking of the headrest 10 on the seat and improve the stability of the headrest 10 on the seat.

[0040] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The mounting member 30 is further formed with a locking cavity 32, the mounting member 30 is formed with an avoiding hole 321 communicating with the locking cavity 32, the inner wall of the locking cavity 32 is formed with a communicating hole 322 communicating with the limiting hole 31, the locking member 40 and the unlocking member 50 are arranged in the locking cavity 32, the locking member 40 is adapted to extend into the fixing hole 21 through the communicating hole 322, and the unlocking member 50 extends out of the locking cavity 32 through the avoiding hole 321.

[0041] Therefore, the integration degree of the mounting member 30, the locking member 40 and the unlocking member 50 can be improved, the space occupation of the mounting member 30, the locking member 40 and the unlocking member 50 can be reduced, so as to reduce the interference of the mounting member 30, the locking member 40 and the unlocking member 50 on the user during use, and further improve the user experience.

[0042] The inner wall of the locking cavity 32 can limit and guide the locking member 40 and the unlocking member 50, which can improve the probability of successfully achieving unlocking and locking, and further reduce the operation difficulty of the operator.

[0043] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The unlocking member 50 is arranged on the side of the locking member 40 facing the avoiding opening 321, and the unlocking member 50 is movably arranged in the locking cavity 32 along the first direction. The locking member 40 is provided with a first matching surface 41, and the end of the unlocking member 50 facing the locking member 40 is provided with a second matching surface 51. In the direction of the unlocking member 50 facing the locking member 40, the first matching surface 41 and the second matching surface 51 both extend obliquely towards the communicating opening 322. The unlocking member 50 is adapted to contact the first matching surface 41 through the second matching surface 51 to push the locking member 40 to move from the first position to the second position.

[0044] In the process of use of the user, when it is needed to unlock the supporting rod 20 from the mounting member 30, the part of the unlocking member 50 extending out of the avoiding opening 321 is pressed to move the unlocking member 50 towards the locking member 40 and make the second matching surface 51 contact the first matching surface 41. Thus, in the process of the unlocking member 50 moving towards the locking member 40, the force applied by the second matching surface 51 to the first matching surface 41 has a component in the direction away from the communicating opening 322, which makes the locking member 40 gradually come out of the fixing hole 21. Therefore, the unlocking of the supporting rod 20 on the seat can be achieved.

[0045] In the process of use of the user, when it is needed to unlock the supporting rod 20 from the mounting member 30, the part of the unlocking member 50 extending out of the avoiding opening 321 is pressed to move the unlocking member 50 towards the locking member 40 and make the second matching surface 51 contact the first matching surface 41. Thus, in the process of the unlocking member 50 moving towards the locking member 40, the force applied by the second matching surface 51 to the first matching surface 41 has a component in the direction away from the communicating opening 322, which makes the locking member 40 gradually come out of the fixing hole 21. Therefore, the unlocking of the supporting rod 20 on the seat can be achieved.

[0046] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The locking member 40 comprises a locking block 42 and a locking pin 43. The locking pin 43 is connected to the side of the locking block 42 facing the communicating opening 322. The first matching surface 41 is formed on the end of the locking block 42 connected to the locking pin 43. The locking pin 43 is adapted to extend into the fixing hole 21.

[0047] The locking pin 43 is easier to extend into the fixing hole 21, the locking block 42 has a larger size, the area of the first matching surface 41 is easier to meet the use requirement, and the structure of the locking member 40 is simpler, so that the production difficulty and product design difficulty are reduced.

[0048] Preferably, the second matching surface 51 is formed with a avoiding space for avoiding the locking pin 43, and the locking pin 43 is located in the avoiding space during the movement of the unlocking member 50 along the first direction, so that the contact area of the first matching surface 41 and the second matching surface 51 is increased.

[0049] During the product design, the size of the locking block 42, the size of the locking pin 43 or the connecting position of the locking pin 43 on the locking block 42 can be adjusted, so that more product design requirements are met.

[0050] In some embodiments of the utility model, as shown in Figure 2 As shown in the drawings, the unlocking member 50 is further formed with a limiting protrusion 52 protruding in a perpendicular direction towards the first direction, the inner wall of the locking cavity 32 is formed with a limiting groove 323 extending along the first direction, and the limiting protrusion 52 is matched in the limiting groove 323. Thus, on the one hand, the limiting protrusion 52 and the limiting groove 323 are matched to limit the movement path of the unlocking member 50 during the movement of the unlocking member 50, and on the other hand, the limiting groove 323 can be matched with the limiting protrusion 52 to prevent the unlocking member 50 from being pulled out of the locking cavity 32.

[0051] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 As shown in the drawings, the reset member 60 is a reset spring, and the reset spring is abutted between the end of the locking member 40 away from the communication port 322 and the inner wall of the locking cavity 32.

[0052] During the unlocking of the support rod 20 by the user, the unlocking member 50 pushes the locking member 40 to gradually pull out of the fixing hole 21 and move to the second position through the contact of the second matching surface 51 and the first matching surface 41, and at the same time, the locking member 40 gradually compresses the reset spring, the reset spring applies an action force to the locking member 40 towards the fixing hole 21, after the height of the headrest 10 is adjusted to the position, the user releases the pressure on the unlocking member 50, the locking member 40 moves to the first position under the action of the action force of the reset spring, the locking member 40 extends into the fixing hole 21, and the action force of the reset spring on the locking member 40 can fix the locking member 40 in the fixing hole 21, so that the user adjusts the height of the headrest 10.

[0053] The return spring is relatively easy to arrange, which can reduce the difficulty of production and design. Preferably, a positioning pin is formed at the end of the locking member 40 away from the fixing hole 21, and one end of the return spring is sleeved on the positioning pin. This can improve the reliability of the return spring between the locking member 40 and the inner wall of the locking cavity 32.

[0054] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the mounting member 30 also has a mounting opening 324 communicating with the locking cavity 32. The mounting opening 324 is located on the side of the mounting member 30 facing away from the clearance opening 321 in the first direction. The headrest assembly 100 also includes a mounting cover plate 70, which covers the mounting opening 324. During assembly, the locking member 40, the resetting member 60, and the unlocking member 50 are installed into the locking cavity 32 through the mounting opening 324, and then the mounting opening 324 is sealed by the mounting cover plate 70. Thus, the assembly of the locking member 40, the resetting member 60, and the unlocking member 50 on the mounting member 30 can be realized. Preferably, the mounting cover plate 70 is bolted to the mounting member 30.

[0055] In some embodiments of this invention, the headrest 10 is angle-adjustably mounted on the support rod 20. During use, the angle of the headrest 10 can be adjusted to meet various user needs and further enhance the user experience.

[0056] In some embodiments of this utility model, such as Figures 1-3 As shown, a first mounting hole 22 is formed on the support rod 20, and a second mounting hole 11 is formed on the headrest 10. The headrest assembly 100 also includes a fastener, which passes through the first mounting hole 22 and the second mounting hole 11 in sequence to connect the headrest 10 and the support rod 20.

[0057] When the angle of the headrest 10 needs to be adjusted, release the fastener, rotate the headrest 10 to the set angle, and then tighten the fastener. In this way, the angle of the headrest 10 on the support rod 20 can be adjusted.

[0058] Preferably, the fastener is a fastening bolt.
