DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments (or, the implementation manners) of the present application will be clearly and completely described below with reference to the drawings. When the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise indicated.

[0048] If the application embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings); if the certain posture changes, the directional indications or positional relationships also change accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0049] As Figure 1 and Figure 2As shown, the headrest of the present application comprises a headrest body 1, an avoiding assembly 2 and a locking mechanism 3. The headrest body 1 is provided with a hair accommodating hole 11, which is recessed from the front side of the headrest body 1 along the thickness direction of the headrest, and is used to accommodate people's hair, i.e. the hair accommodating hole 11 is used to accommodate the hair bump generated when people coil their hair, such as the bump generated by a ponytail, a bun and other hairstyles. The avoiding assembly 2 is movably arranged in the headrest body 1 and can move relative to the headrest body 1. The locking mechanism 3 is connected to the headrest body 1 and can be used to lock the avoiding assembly 2.

[0050] The headrest also comprises a first state and a second state. Specifically, when the headrest is in the first state, the avoiding assembly 2 moves to the hair accommodating hole 11 to fill the hair accommodating hole 11. In this state, the front side of the avoiding assembly 2 is flush with the front side of the headrest body 1, i.e. there is no obvious difference between the front side of the avoiding assembly 2 and the front side of the headrest body 1, and they are generally smooth. When the headrest is in the second state, the avoiding assembly 2 moves away from the hair accommodating hole 11 and is locked to the locking mechanism 3. In this state, the hair accommodating hole 11 can accommodate the bump generated by a ponytail, a bun and other hairstyles.

[0051] In this way, the headrest can not only support the head with a smooth hairstyle at the back, but also accommodate the bump generated after coiling the hair through the hair accommodating hole 11, improve the fit of the headrest with the coiled hair, and thus improve the comfort and safety of the headrest in supporting the head. At the same time, it can also increase the versatility of the headrest and improve the user's experience.

[0052] Further combining Figures 3 to 6 As shown, in some embodiments, the headrest body 1 comprises a shell 12, a support 13 and a foaming piece 14. The support 13 is fixed in the shell 12, and the avoiding assembly 2 is slidably arranged in the shell 12 and is in sliding connection with the support 13. The shell 12 can comprise a front shell 121 and a rear shell 122 which are detachably connected, the support 13 is fixed to the front shell 121 and / or the rear shell 122, and the avoiding assembly 2 is arranged in the front shell 121. Along the front-rear direction of the headrest, the cavity of the front shell 121 accommodating the avoiding assembly 2 is in communication with the hair accommodating hole 11 and is located behind the hair accommodating hole 11.

[0053] Based on the above design, the support 13 is preferably fixed to the rear shell 122, and the support 13 comprises a guide cylinder 131 and a support plate 132 fixed to the rear shell 122. The guide cylinder 131 is fixed to the side of the support plate 132 away from the hair accommodating hole 11, i.e. the guide cylinder 131 is located at the rear side of the support plate 132, and the guide cylinder 131 is used to accommodate part of the avoiding assembly 2. Specifically, the avoiding assembly 2 comprises a sliding piece 21 and a foaming block group 22 connected to the sliding piece 21. Along the thickness direction of the headrest, the sliding piece 21 is arranged in the shell 12 and is in sliding connection with the support 13, and the sliding piece 21 can drive the foaming block group 22 to fill or move away from the hair accommodating hole 11.

[0054] Further, the sliding member 21 is arranged in the front shell 121 and the support plate 132, and is slidably connected in the guide cylinder 131, so that the foaming block group 22 is filled in or moved out of the hair accommodating hole 11. When the headrest is in the second state, in order to make the space of the headrest body 1 for accommodating the hair bump larger, the foaming block group 22 can be moved to the inside of the front shell 121 along with the sliding member 21.

[0055] In order to make the sliding member 21 more stable when moving in the guide cylinder 131, one end of the guide cylinder 131 located behind the support plate 132 abuts against the inner side of the rear shell 122. In order to make the guiding effect of the sliding member 21 in the guide cylinder 131 better, the guide cylinder 131 is located on the opposite sides of the support plate 132, and the cavity of the guide cylinder 131 for accommodating the sliding member 21 penetrates through the support plate 132.

[0056] Further combining Figures 7 to 9 As shown, the inner circumferential side of the guide cylinder 131 includes a second connecting part 1311 and a third connecting part 1312, and the sliding member 21 includes a first connecting part 210 and a fourth connecting part 212. The second connecting part 1311 cooperates with the first connecting part 210 to limit the rotation and disengagement of the sliding member 21 from the guide cylinder 131.

[0057] Specifically, the first connecting part 210 is a claw structure, and is located at one end of the sliding member 21 away from the foaming block group 22, and along the radial direction of the sliding member 21, the edge of the first connecting part 210 protrudes from the circumferential side of the sliding member 21. The second connecting part 1311 is a groove arranged in the inner circumferential side of the guide cylinder 131, and the claw structure of the first connecting part 210 is engaged in the groove structure of the second connecting part 1311. In order to improve the engagement stability between the guide cylinder 131 and the sliding member 21, the second connecting part 1311 and the first connecting part 210 are each provided with at least two. Among them, along the radial direction of the guide cylinder 131, the second connecting part 1311 can penetrate through one side of the guide cylinder 131. Since the claw is engaged in the groove, the rotation and disengagement of the sliding member 21 from the guide cylinder 131 can be limited during the sliding process of the sliding member 21.

[0058] In other embodiments, the first connecting part 210 can also be a groove structure arranged in the outer circumferential side of the sliding member 21, and the second connecting part 1311 is a claw structure.

[0059] In some embodiments, the third clamping portion 1312 cooperates with the fourth clamping portion 212 to guide the sliding member 21 and further prevent the sliding member 21 from rotating in the guide cylinder 131. Specifically, the third clamping portion 1312 is a guide groove recessed from the inner circumferential side of the guide cylinder 131, and the fourth clamping portion 212 is a guide rail protruding from the outer circumferential side of the sliding member 21, which is arranged in the guide groove to guide the movement of the sliding member 21 and prevent the sliding member 21 from rotating. Of course, the third clamping portion 1312 can also be a guide rail protruding from the inner circumferential side of the guide cylinder 131, and the fourth clamping portion 212 can be a guide groove recessed from the outer circumferential side of the sliding member 21.

[0060] The inner circumferential side of the guide cylinder 131 is further provided with a plurality of damping protrusions 1313. Along the circumference of the guide cylinder 131, the damping protrusions 1313 are arranged at intervals on the inner circumferential side of the guide cylinder 131 and fit the outer circumferential side of the sliding member 21. In this way, the guide cylinder 131 fits the sliding member 21 at multiple angles through the plurality of damping protrusions 1313, thereby improving the stability and damping feeling of the sliding member 21 sliding in the guide cylinder 131.

[0061] Further combining Figure 10 and Figure 11 To improve the convenience and firmness of the connection between the support member 13 and the rear shell 122, the rear shell 122 includes a middle connecting plate 1221 and a positioning ring 1222. The middle connecting plate 1221 is located behind the support plate 132, and the support plate 132 is fixed to the middle connecting plate 1221. The guide cylinder 131 penetrates the middle connecting plate 1221, and one end of the guide cylinder 131 located behind the support plate 132 is clamped to the positioning ring 1222.

[0062] The foaming member 14 covers the shell 12, and the hair containing hole 11 is located in the foaming member 14. When the headrest is in the first state, the foaming block group 22 is located in the hair containing hole 11, and the surface of the foaming block group 22 is flush with the surface of the foaming member 14. When the headrest is in the second state, the foaming block group 22 moves towards the inside of the shell 12 away from the hair containing hole 11. It is worth noting that due to the material, workmanship error and installation error of the headrest, when the headrest is in the first state, the surface of the foaming block group 22 is approximately flush with the surface of the foaming member 14. However, due to the particularity of the shape of the headrest, if the front surface of the headrest is recessed or protruding in an arc shape, the surface of the foaming block group 22 and the surface of the foaming member 14 have no obvious difference, and tend to be smooth.

[0063] Combining Figure 9 , Figure 11 and Figure 12As shown, in some embodiments, the foaming block set 22 comprises a foaming body 221 and a detachable plate 222, and the sliding member 21 is provided with an engaging plate 213 at the end thereof adjacent to the foaming block set 22. The detachable plate 222 is detachably connected to the engaging plate 213, and the foaming body 221 is fixed to the side of the detachable plate 222 away from the engaging plate 213. In this way, the efficiency of disassembling and assembling the avoiding assembly 2 is improved.

[0064] The avoiding assembly 2 can further comprise a first elastic member 23, which is located in the guide cylinder 131 and abuts against the sliding member 21 at one end and the rear side of the shell 12 at the other end. When the headrest is in the second state, the first elastic member 23 is compressed. In this way, the avoiding assembly 2 can be converted from the second state to the first state of the headrest under the elastic force of the first elastic member 23, i.e., the first elastic member 23 can push the foaming block set 22 to move into the hair accommodating hole 11 to fill the hair accommodating hole 11.

[0065] To improve the stability of the first elastic member 23 during compression and rebound, the rear shell 122 comprises a first positioning column 1223 located in the positioning ring 1222, and the end of the sliding member 21 away from the foaming block set 22 is provided with a second positioning column 214, and the two ends of the first elastic member 23 are respectively sleeved on the first positioning column 1223 and the second positioning column 214. It is worth noting that the sliding member 21 is provided with an end cavity 215, which is concave from the end of the sliding member 21 away from the foaming block set 22, the second positioning column 214 is located in the end cavity 215, and part of the first elastic member 23 is also located in the end cavity 215.

[0066] To ensure that the first elastic member 23 has sufficient elastic force to assist the movement of the avoiding assembly 2, the first elastic member 23 can be provided with multiple and arranged at intervals along the circumference of the guide cylinder 131.

[0067] In other embodiments, the first elastic member 23 is located on the circumferential side of the sliding member 21, and one end of the first elastic member 23 abuts against the end of the sliding member 21 away from the support plate 132, i.e., one end of the first elastic member 23 abuts against the engaging plate 213, and the other end of the first elastic member 23 abuts against the support plate 132. In this embodiment, the first elastic member 23 can be provided with multiple and arranged at intervals along the circumference of the sliding member 21.

The button 31 is connected to the shell 12 and connected with the locking piece 30, the button 31 can drive the locking piece 30 to move, thereby locking and releasing the sliding piece 21. Specifically, the outer circumferential side of the sliding piece 21 is provided with a clamping groove 211, when the headrest is in the second state, the locking piece 30 is clamped in the clamping groove 211 to lock the sliding piece 21. When the headrest needs to be converted to the first state, the button 31 drives the locking piece 30 to move to release the clamping groove 211.

[0069] The clamping groove 211 is provided with a plurality of clamping grooves 211, which are arranged in the thickness direction of the headrest, wherein the plurality of clamping grooves 211 at least comprises a first clamping groove 2111 and a second clamping groove 2112 adjacent to the opposite ends of the sliding piece 21, when the headrest is in the first state, the locking piece 30 is clamped in the first clamping groove 2111, when the headrest is in the second state, the locking piece 30 is clamped in the second clamping groove 2112. In addition, a plurality of third clamping grooves (not shown) can be arranged between the first clamping groove 2111 and the second clamping groove 2112, and the locking piece 30 can be clamped in the third clamping groove. In this way, the avoiding assembly 2 can be adjusted in multiple stages relative to the headrest body 1, thereby enriching the selection of the headrest and improving the use experience.

[0070] Further combined Figures 14 to 17 As shown, the sliding piece 21 penetrates the locking piece 30, specifically, the locking piece 30 is provided with a through hole 301, the locking piece 30 is connected to the support piece 13 by sliding, and the sliding piece 21 penetrates the through hole 301. The locking mechanism 3 can also comprise a second elastic piece 32, the second elastic piece 32 abuts the locking piece 30 and the support piece 13 respectively. When the locking piece 30 is released from the clamping groove 211, the second elastic piece 32 is compressed. In this way, the button 31 can be reset, and the locking piece 30 can be automatically clamped in the clamping groove 211 and tightly abutted on the clamping groove 211.

[0071] In order to improve the stability of the locking piece 30 when sliding on the support piece 13, the support piece 13 comprises a support plate 132 and a sliding cavity 133 arranged on the support plate 132, the locking piece 30 and the second elastic piece 32 are located in the sliding cavity 133, and one end of the second elastic piece 32 abuts the locking piece 30 and the other end abuts the inner side of the sliding cavity 133. Specifically, the sliding cavity 133 is provided with an abutting block 1331 and a spring containing cavity 1332 arranged in the end of the abutting block 1331, the spring containing cavity 1332 is communicated with the sliding cavity 133, and the second elastic piece 32 is located in the spring containing cavity 1332. In order to improve the smoothness of the locking piece 30 when sliding, the second elastic piece 32 and the spring containing cavity 1332 correspondingly are provided with two, and the two second elastic pieces 32 are located on the opposite sides of the locking piece 30.

[0072] The locking member 30 comprises a locking plate 302 and a locking tongue 303. A through hole 301 is formed in the locking plate 302, and the button 31 is connected to the locking plate 302.
