Detailed Implementation

[0016] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figure 1 , Figure 2 , Figure 18-19As shown, a car headrest with side pillows includes a headrest 1, an internal connecting bracket 11 extending outwards to opposite sides to form connecting portions 12, a fixing cavity at the rear center of the connecting bracket 11, and connecting portions 12 located on opposite left and right sides of the headrest 1. The headrest 1 also contains flexible filling material, such as sponge, located in front of the connecting portions 12 to provide flexible support for the head. The headrest 1 supports the head. At least two oppositely arranged side pillow assemblies 2 are detachably and rotatably connected to the connecting portions 12 of the headrest 1, providing support for both sides of the head. A fixing mechanism 3 is also included. The headrest 1 and side pillow assembly 2 are detachably or fixedly connected to the headrest 1. The fixing mechanism 3 is used to fix the headrest 1 and side pillow assembly 2 to the car seat. The fixing mechanism 3 includes a housing, a left clamping arm 31 and a right clamping arm 31 slidably disposed on opposite sides of the housing, and a hook 33 rotatably connected to the rear end of the housing. The hook 33 can be rotated and folded for storage. When unfolded, it can provide a hook function for rear passengers, which is very convenient. The front end of the fixing mechanism 3 is connected to the fixing cavity on the connecting bracket 11. The left and right sides of the housing of the fixing mechanism 3 have sliding grooves of a certain depth. The left clamping arm 31 and the right clamping arm 31 are inserted into the corresponding sliding grooves and are detachably connected. The left clamping arm 31 and the right clamping arm 31 have the same structure. Both are J-shaped structures, with the left and right clamping arms 31 arranged horizontally. A fifth tooth 311 of a certain length is provided on the left and right clamping arms 31 along their length. The fixing mechanism 3 also includes a third button body 32 and a sixth elastic body located below the third button body 32. The sixth elastic body is a spring. The top of the third button body 32 penetrates the corresponding housing and extends beyond it. A sixth tooth 321 is provided on the upper surface of the third button body 32 at a position corresponding to the fifth tooth 311. The fifth tooth 311 and the sixth tooth 321 mesh. When the corresponding third button body 32 is pressed, the sixth elastic body compresses and deforms, and the sixth tooth 321 on the third button body 32 disengages from the fifth tooth 311. The left clamping arm 31 or... The right clamping arm 31 is in the unlocked state. At this time, the clamping distance between the two clamping arms can be adjusted, and the left clamping arm 31 or the right clamping arm 31 can be removed. When the user releases the third button body 32, the sixth elastic body resets to form an elastic support for the third button body 32. At this time, the left clamping arm 31 or the right clamping arm 31 cannot be moved left or right. During installation, first move the left clamping arm 31 or the right clamping arm 31 to a suitable position so that there is enough installation space between them. Then, align the hook-shaped structure at the front end of the left clamping arm 31 and the right clamping arm 31 with the two metal connecting rods of the car seat headrest, close the left clamping arm 31 and the right clamping arm 31 until the hook-shaped structure of the two clamping arms is firmly locked on the two metal connecting rods of the car seat headrest, and complete the installation and fixation of the headrest 1. In this way, by setting two side pillow components 2 on the headrest 1, the user's head is supported in both the left and right directions and the back, which is more comfortable and effectively enhances the user experience.

[0018] like Figure 1-8 As shown, the side pillow assembly 2 includes a side pillow 22, a first connecting mechanism 21, and a second connecting mechanism 23 disposed on the side pillow 22. The side pillow 22 is rotatably connected to the second connecting mechanism 23, and the side pillow 22 is slidably connected to the first connecting mechanism 21 through the second connecting mechanism 23. The first connecting mechanism 21 includes a connecting rod 211, which is generally L-shaped. A track hole 212 is provided on the connecting rod 211 along its length. The track hole 212 penetrates the connecting rod 211 and is a rectangular or elliptical hole. A limiting platform 213 is provided in the track hole 212, and first teeth 214 are provided on opposite sides of the limiting platform 213. The first connecting mechanism 21 also includes a component rotatably connected to the connecting rod 211. The plug-in portion 215 is used to mate with the connecting portion 12. The plug-in portion 215 contains a first elastic body 216 and a first button body 217 positioned above the first elastic body 216. A button mounting cavity 210 is formed on the plug-in portion 215, within which both the first button body 217 and the first elastic body 216 are located. The first elastic body 216 is used for pressing and resetting the first button body 217, and is configured as a spring. The first button body 217 penetrates the corresponding housing of the plug-in portion 215 and is protruding. The first button body 217 is pressed and connected to the plug-in portion 215. A positioning boss 218 is laterally provided on the surface of the plug-in portion 215. The connecting portion 12 has a tubular structure, and its interior is a plug-in cavity 120. The insertion cavity 120 has a circular, polygonal, or irregularly shaped cavity of a certain depth. A locking hole 121 is provided on the connecting part 12 at a position corresponding to the first button body 217. The inner wall of the locking hole 121 is provided with a positioning groove 122 that matches the positioning boss 218. Through the cooperation of the first button body 217 and the locking hole 121, the side pillow assembly 2 can be quickly installed and removed. When installing the side pillow assembly 2, firstly, align the front end of the insertion part 215 with the insertion cavity 120, where the positioning boss 218 is aligned with the positioning groove 122, and then push the connecting rod 2. 11. Until the first button body 217 is inserted into the locking hole 121, the first button body 217 protrudes from the locking hole 121, forming the installation and locking state of the side pillow assembly 2. When the user needs to remove the side pillow assembly 2 for cleaning or storage, simply press the first button body 217. The first button body 217 is pressed down, the first elastic body 216 is compressed and deformed by force, and the first button body 217 is released from the locking hole 121. At this time, the side pillow assembly 2 is in the unlocked state. The user pulls the side pillow assembly 2 outward, and the plug part 215 is released from the plug cavity 120 on the connecting part 12, completing the quick disassembly. In this way, by setting the first button body 217 to match the card hole 121, the side pillow assembly can be quickly disassembled and installed.

[0019] Example 2 like Figures 1-8 and Figure 17 As shown, a car headrest with side pillows includes a first damping mechanism 10 in the insertion part 215. The first damping mechanism 10 generates a damping effect when the first connecting mechanism 21 rotates. The first damping mechanism 10 includes an arc-shaped member 101 disposed inside the insertion part 215 and a second elastic body 102. An insertion cavity 2111 is provided at the position where the connecting rod 211 connects to the insertion part 215. The rear end of the insertion part 215 is inserted into the insertion cavity 2111. The insertion part 215 is rotatably connected to the connecting rod 211 via a rotating shaft, thus forming a rotating state of the connecting rod 211. A plurality of damping grooves 123 are provided in the inner ring of the insertion cavity 2111. The top of the arc-shaped member 101 has a damping platform 1011 extending into the damping grooves 123. The second elastic body 102 is disposed below the bow-shaped member 101. In this embodiment, the bow-shaped member 101 and the second elastic body 102 are located at the tail end of the insertion part 215. There are two bow-shaped members 101 and two elastic bodies 102. Two springs are located between the two bow-shaped members 101. The two bow-shaped members 101 are arranged vertically opposite each other. The damping platform 1011 passes through the housing of the corresponding insertion part 215. The damping groove 123 is arranged correspondingly to the damping platform 1011. The damping platforms 1011 on the two bow-shaped members 101 are facing the corresponding damping groove 123, forming an elastic support for the bow-shaped member 101. When the damping platform 1011 of the bow-shaped member 101 is inserted into the damping groove 123, it is the locked state of the rotation position of the side pillow assembly 2.

[0020] Thus, by setting the first damping mechanism 10, the connecting rod 211 has a certain damping force when it rotates, so as to prevent the connecting rod 211 from rotating arbitrarily. By setting the connecting rod 211 and the rotatable connector 215, the side pillow 22 can be adjusted back and forth in the circumferential direction to provide the best support for both sides of the user's face and improve the fit with both sides of the head during use.

[0021] Example 3 like Figure 7-13As shown, a car headrest with side pillows includes a second connecting mechanism 23 comprising a base 231, a rotating disk 232, and a second damping mechanism 20. The base 231 is embedded in the side pillow 22 and has a rotating cavity 233 inside. The base 231 includes an upper shell 2311 and a lower shell 2312. The rotating cavity 233 is located on the lower shell 2312, and the rotating disk 232 is rotatably connected within the rotating cavity 233. The second damping mechanism 20 generates a damping effect when the rotating disk 232 rotates. As a result, the top of the rotating disk 232 extends upward through the track hole 212 on the connecting rod 211. The top of the rotating disk 232 is provided with a cover plate 234, a second button body 235, and a third elastic body 236. The third elastic body 236 is a spring, located below the second button body 235, and is used for pressing and resetting the second button body 235. The top of the second button body 235 penetrates the cover plate 234, which is located in the track hole 212. The cover plate 234 is fixedly connected to the rotating disk 232, which is located inside the track hole 212. The two form a clamping state on the limiting platform 213. When the side pillow 22 moves up and down or left and right, the top of the cover plate 234 and the rotating disk 232 slide up and down or left and right in the track hole 212. A fourth tooth 237 is provided on the second button body 235 at the position opposite to the first tooth 214. The fourth tooth 237 is provided on the second button body 235. On the upper surface of 5, the first tooth 214 engages with the fourth tooth 237. When the second button body 235 is pressed, the fourth tooth 237 on the second button body 235 moves away from the first tooth 214. At this time, the second connecting mechanism 23 is in the sliding unlocked state. When the second button body 235 is released, under the reset force of the third elastic body 236, the second button body 235 resets, and the first tooth 214 engages with the fourth tooth 237, forming a locked state for the second connecting mechanism 23. In this way, by setting the second connecting mechanism 23 and the track hole 212, the side pillow 22 connected to the second connecting mechanism 23 can move back and forth to adjust the support height of the side pillow 22 to adapt to users of different heights and meet different needs.

[0022] Example 4 like Figure 14-15As shown, a car headrest with side pillows includes a second damping mechanism 20 comprising a second tooth 201 annularly disposed at the bottom of the rotating cavity 233 and a third tooth 202 disposed on the rotating disk 232. The third tooth 202 is opposite to and meshes with the second tooth 201. A groove is formed at the center of the rotating disk 232, and a rotating shaft 240 is disposed in the groove. A fifth elastic body 241, which is a spring, is sleeved on the rotating shaft 240. The rotating shaft 240 extends through the groove into the rotating cavity 233, and the front end of the rotating shaft 240 is an outer... The rotating cavity 233 has a threaded opening with an internal thread. The rotating shaft 240 is connected to the base 231 via an external thread. When the third tooth 202 on the rotating disk 232 meshes with the second tooth 201, the fifth elastic body 241 provides elastic contact with the rotating disk. When the third tooth 202 on the rotating disk 232 disengages from the meshing second tooth 201, the fifth elastic body 241 compresses and deforms, giving the rotating disk 232 a certain damping force when rotating, and also locking the rotation position of the side pillow 22.

[0023] Example 4 like Figure 10-13 As shown, a car headrest with side pillows includes a second damping mechanism 20 comprising a plurality of limiting grooves 203 arranged around the bottom of the rotating cavity 233, as well as limiting posts 204 and a fourth elastic body 205. In this embodiment, there are multiple limiting grooves 203, and four limiting posts 204 and four fourth elastic bodies 205 are provided. The front end of the limiting post 204 is a spherical structure. The limiting post 204 is embedded in the rotating disk 232. The fourth elastic body 205 is located below the limiting post 204, forming an elastic support for the limiting post 204. The bottom of the rotating disk 232 is provided with four mounting slots 200. The four limiting posts 204 and the fourth elastic bodies 205 are respectively arranged in the four mounting slots 200. The front end of the limiting post 204 abuts against the limiting groove 203. When the front end of the limiting post 204 is engaged in the limiting groove 203, the rotation position of the rotating disk 232 is locked.

[0024] In summary, compared with the prior art, this application provides greater comfort and effectively enhances the user experience by setting two side pillow components 2 on the headrest 1, which simultaneously provides support for the user's head in the left and right directions and the back. Furthermore, by setting the first damping mechanism 10, the connecting rod 211 has a certain damping force when it rotates, preventing the connecting rod 211 from rotating arbitrarily. By setting the connecting rod 211 and the rotatable connecting part 215, the side pillow 22 can be adjusted back and forth in the circumferential direction to form the best support effect on both sides of the user's face and improve the fit with both sides of the human head during use. By setting the second connecting mechanism 23 and the track hole 212, the side pillow 22 connected to the second connecting mechanism 23 can move back and forth to adjust the support height of the side pillow 22 to adapt to users of different heights and meet different needs. Since the side pillow assembly 2 is mounted on the headrest 1, the headrest 1 and the side pillow 22 can be installed and fixed using only one fixing mechanism 3, which is very convenient. The above is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
