DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figures 1 to 8 As shown, a four-way headrest 1 of the utility model comprises: a headrest support rod 2, which is inserted into the headrest 1, and a plurality of first card slots 3 are arranged at intervals on the headrest support rod 2; a front cover assembly 4, which is arranged in the headrest 1, and the front cover assembly 4 has a plurality of second card slots 5 arranged at intervals; a rear cover assembly 6, which is arranged in the headrest 1 and is arranged opposite to the front cover assembly 4, and the rear cover assembly 6 has a sliding rod 7 and a first clamping member 8 and a second clamping member 9 both of which are movably abutted against the sliding rod 7, and the first clamping member 8 and the second clamping member 9 are respectively provided. The first clamping slot 3 is movably clamped, the second clamping member 9 is movably clamped with the second clamping slot 5, and the sliding rod 7 is used to drive the first clamping member 8 to disengage from the first clamping slot 3 and the second clamping member 9 to disengage from the second clamping slot 5; the front cover assembly 4 and the rear cover assembly 6 can move in the vertical direction relative to the headrest support rod 2 because the first clamping member 8 is disengaged from the first clamping slot 3; the front cover assembly 4 can move in the horizontal direction relative to the rear cover assembly 6 because the second clamping member 9 is disengaged from the second clamping slot 5.

[0040] When the sliding rod 7 is pushed, the first clamping member 8 and the second clamping member 9 will be disengaged from the first slot 3 and the second slot 5 respectively. Specifically, the disengagement of the first clamping member 8 from the first slot 3 allows the front cover assembly 4 and the rear cover assembly 6 to move as a whole in the vertical direction relative to the headrest support rod 2, thereby unlocking the vertical adjustment of the headrest 1 on the car seat. At the same time, the disengagement of the second clamping member 9 from the second slot 5 enables the front cover assembly 4 to move in the horizontal direction relative to the rear cover assembly 6, thereby realizing the front and rear direction adjustment unlocking of the headrest 1 on the car seat. Through this design, the adjustment and unlocking of the headrest 1 becomes simple and intuitive. The position of the headrest 1 can be easily unlocked and adjusted by pushing the sliding rod 7 to adapt to personal needs and improve riding comfort.

[0041] Specifically, the rear cover assembly 6 also includes: a rear shell 10, on which a first cavity 11 and a second cavity 12 located above the first cavity 11 are arranged, the first cavity 11 is connected to the second cavity 12, the sliding rod 7 is movably arranged in the first cavity 11, and one side of the second clamping member 9 is movably arranged at the connection point between the first cavity 11 and the second cavity 12; a torsion spring 13, whose sleeve is arranged on the rear shell 10, one pin of the torsion spring 13 is arranged on the rear shell 10, and the other pin abuts against the sliding rod 7; a first elastic member 14, one end of which abuts against the inner wall of the second cavity 12, and the other end abuts against the second clamping member 9, and the first elastic member 14 is preferably a spring.

[0042] When the sliding rod 7 is pushed to move in the first cavity 11, the torsion spring 13 and a pin against which the sliding rod 7 abuts are compressed and deformed, and at the same time, the second clamping member 9 is driven to disengage from the second clamping slot 5. At this time, the first elastic member 14 is compressed and deformed due to the movement of the second clamping member 9. Once the force pushing the sliding rod 7 is removed, the torsion spring 13 releases its stored energy and drives the sliding rod 7 to reset in the first cavity 11. At the same time, the sliding rod 7 no longer applies force to the second clamping member 9. The second clamping member 9 is reset under the action of the restoring force of the first elastic member 14 and is re-connected with the corresponding second clamping slot 5.

[0043] In order to allow the second clamping member 9 to movably abut against the sliding rod 7, an inclined block 15 is provided on one side of the second clamping member 9, and an inclined groove 16 is provided on one side of the sliding rod 7. One end of the inclined block 15 is inserted into the connection between the first cavity 11 and the second cavity 12 and movably abuts against the inclined groove 16. The inclined block 15 moves along the inclined surface of the inclined groove 16 according to the movement of the sliding rod 7. When the sliding rod 7 is pushed to move in the first cavity 11, the inclined block 15 moves along the bottom of the inclined groove 16 to the end of the inclined groove 16. This process will drive the second clamping member 9 to move upward, so that it is disengaged from the second clamping groove 5. At the same time, the first elastic member 14 is compressed and elastically deformed.

[0044] Specifically, first clamping members 8 are disposed on both sides of the rear housing 10 . The first clamping members 8 are made of steel wire and have a first portion 17 fixed to the rear housing 10 and a second portion 18 movably clamped to the first clamping slot 3 .

[0045] Specifically, through holes 19 are provided on both sides of the rear shell 10, and headrest support rods 2 are inserted in the through holes 19. The second parts 18 on the first clamping members 8 on both sides are respectively inserted in the through holes 19 and movably engaged with the first clamping grooves 3 on the headrest support rods 2. When there is no external force, the engagement of the second part 18 with the first clamping grooves 3 maintains the stability of the relative position of the rear shell 10 and the headrest support rod 2, thereby maintaining the stability of the relative position of the headrest 1 and the car seat. When the position of the headrest 1 needs to be adjusted, the sliding rod 7 is pushed to move in the first cavity 11, thereby driving the first clamping member 8 to move, so that the second part 18 is disengaged from the first clamping groove 3, and then the rear shell 10 can be moved in the vertical direction relative to the headrest support rod 2, thereby realizing the adjustment and unlocking of the headrest 1 relative to the car seat in the vertical direction.

[0046] In order to ensure that the first clip 8 can respond to the movement of the sliding rod 7, first perforations 20 are provided on both sides of the sliding rod 7. One end of the second part 18 on the first clip 8 made of steel wire on both sides passes through the through holes 19 and is movably inserted into the corresponding first perforations 20 and movably abuts against the inner side walls of the first perforations 20. When the sliding rod 7 is pushed to move along the first cavity 11, the inner side walls of the first perforations 20 will contact and exert force with the second part 18, causing the second part 18 to undergo elastic deformation and disengage from the first slot 3 on the headrest support rod 2. When the force pushing the sliding rod 7 disappears, the inner side walls of the first perforations 20 separate from the second part 18, the first clip 8 restores its elastic deformation, and the second part 18 returns to its initial position and re-engages with the corresponding first slot 3. This design ensures that the first clip 8 can move synchronously with the sliding rod 7 to achieve adjustment and unlocking of the headrest 1 in the vertical direction.

[0047] Specifically, the front cover assembly 4 includes: a front shell 21, which is arranged in the headrest 1 and is arranged opposite to the rear shell 10; a guide column 22, a plurality of guide columns 22 are arranged on the front shell 21, and a plurality of guide holes 23 are arranged on the rear shell 10, the guide columns 22 are respectively movably inserted in the guide holes 23, and the guide columns 22 can move relative to the guide holes 23 due to the horizontal movement of the front shell 21 relative to the rear shell 10; a moving rod 24, which is arranged on the front shell 21, and a second through hole 25 is arranged on the rear shell 10, which is located in the middle position of the first cavity 11, the moving rod 24 is inserted in the second through hole 25, and the second card slots 5 are arranged on the moving rod 24 at intervals.

[0048] The engagement of the second clamping member 9 with the second clamping slot 5 ensures the stability of the relative position between the front shell 21 and the rear shell 10. When the sliding rod 7 drives the second clamping member 9 to disengage from the second clamping slot 5, the front shell 21 can move horizontally relative to the rear shell 10, thereby unlocking the headrest 1 for front and rear adjustment relative to the car seat. When adjusting the headrest 1 front and rear, the guide column 22 on the front shell 21 moves along the guide hole 23 on the rear shell 10, ensuring smooth and accurate adjustment. The force pushing the sliding rod 7 is removed, and the sliding rod 7 returns to its initial position in the first cavity 11 driven by the first elastic member 14. At the same time, the second clamping member 9 is re-engaged with the corresponding second clamping slot 5 under the action of the restoring force of the first elastic member 14, ensuring a stable connection between the front shell 21 and the rear shell 10.

[0049] In order to realize the movable snap connection between the second clamping member 9 and the second clamping slot 5, the second cavity 12 is connected with the second through hole 25, and the end of the second clamping member 9 away from the first elastic member 14 passes through the connection between the second cavity 12 and the second through hole 25 and forms an movable snap connection with the second clamping slot 5.

[0050] In order to push the sliding rod 7 , a manual button 26 is further provided on one side of the headrest 1 . The manual button 26 abuts against one end of the sliding rod 7 . Pressing the manual button 26 pushes the sliding rod 7 to move horizontally in the first cavity 11 .

[0051] Specifically, the manual button 26 includes: a fixing seat 27, which is inserted into the side of the headrest 1; a push block 28, which is movably arranged on the fixing seat 27; a second elastic member 29, one end of which is sleeved on the push block 28, and the other end is against the sliding rod 7, ensuring that when the push block 28 is pressed, the second elastic member 29 can effectively transmit force to the sliding rod 7 to push it to move horizontally. The stroke of the push block 28 pushing the sliding rod 7 to move is carefully designed to ensure that the sliding rod 7 drives the first clamping members 8 on both sides of the rear housing 10 and the headrest support rod 2 The first card slot 3 on the seat is just disengaged from the card connection, and the second card connector 9 is disengaged from the second card slot 5, so that the front cover assembly 4 and the rear cover assembly 6 can not only move in the vertical direction relative to the headrest support rod 2 to unlock the vertical adjustment of the headrest 1 on the car seat, but the front cover assembly 4 can also move in the horizontal direction relative to the rear cover assembly 6 to achieve the front and rear direction adjustment unlocking of the headrest 1 on the car seat. This design cleverly combines the vertical and horizontal adjustment unlocking functions, which can be completed by operating a single manual button 26, and the second elastic member 29 is preferably a spring.
