[0040] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0041] The following is for reference. Figures 1-11 The present invention describes a headrest 100 for a vehicle according to an embodiment of the present invention, which can be applied to a vehicle.

[0042] Combination Figures 1-6 As shown, the headrest 100 of a vehicle according to an embodiment of the present utility model may mainly include: an outer cover 10, an adjustment component 20, and a connecting rod 30. The adjustment component 20 includes a frame component 21, a main body component 22, a locking component 23, and an unlocking component 24. The frame component 21, the main body component 22, the locking component 23, and the unlocking component 24 are all disposed inside the outer cover 10. The outer cover 10 is suitable for direct contact with the head, so that the headrest 100 can be adjusted while ensuring the comfort of the headrest 100.

[0043] Furthermore, the frame member 21 is an important structure of the adjustment component 20, which can provide support for the locking member 23, the main body member 22 and the unlocking member 24. The locking member 23 is disposed on the frame member 21, the main body member 22 passes through the frame member 21 in the front-rear direction and can move relative to the frame member 21 in the front-rear direction, and the unlocking member 24 is movably disposed on the frame member 21. The unlocking member 24 is located at the lower part of the frame member 21. This makes the structure of the adjustment component 20 compact, which is conducive to reducing the space occupied by the adjustment component 20. This not only reduces the space occupied by the headrest 100 in the vehicle, but also makes the adjustment component 20 in this embodiment of the present invention applicable to headrests 100 with different styles.

[0044] Furthermore, the main body 22 is connected to the outer cover 10, the upper end of the connecting rod 30 passes through the outer cover 10 and the unlocking member 24 located below the frame member 21, and extends into the frame member 21 and is connected to the frame member 21. The lower end of the connecting rod 30 is connected to the seat back of the vehicle, so that the headrest 100 can be fixed to the upper end of the seat back of the vehicle, so that the headrest 100 is suitable for contacting the head and providing support for the head.

[0045] Furthermore, the main body 22 and the locking member 23 are selectively locked. When the main body 22 and the locking member 23 are locked, the position of the main body 22 relative to the frame member 21 in the front-back direction remains unchanged, thus keeping the headrest 100 in its current position to support the head. When the main body 22 and the locking member 23 are disengaged, the main body 22 can move relative to the frame member 21 in the front-back direction to change the position of the headrest 100 in the front-back direction.

[0046] Furthermore, the frame member 21 can move in the vertical direction relative to the connecting rod 30, that is, the frame member 21 can drive the main body member 22, and then drive the outer cover member 10 to move in the vertical direction relative to the connecting rod 30. This allows the headrest 100 to move in the vertical direction relative to the seat back of the vehicle, so as to realize the vertical adjustment of the headrest 100.

[0047] Furthermore, the unlocking component 24 and the connecting rod 30 are selectively locked. When the unlocking component 24 and the connecting rod 30 are locked, the position of the frame component 21 relative to the connecting rod 30 in the vertical direction remains unchanged, so that the frame component 21 is fixed at the current height position, thereby allowing the headrest 100 to support the head at the current height. When the unlocking component 24 and the connecting rod 30 are unlocked, the frame component 21 can move in the vertical direction relative to the connecting rod 30, thereby allowing the frame component 21 to drive the main body component 22 and the outer cover component 10 to move vertically relative to the connecting rod 30, thus realizing the adjustment of the vertical height of the headrest 100.

[0048] Furthermore, when the unlocking member 24 is disengaged from the connecting rod 30, the unlocking member 24 drives the locking member 23 to disengage from the main body member 22. Thus, when the unlocking member 24 is disengaged from the connecting rod 30, not only can the frame member 21 move up and down relative to the connecting rod 30, but the main body member 22 can also move back and forth relative to the frame member 21. This configuration allows for simultaneous adjustment of the headrest 100 in both the back-and-forth and up-and-down directions, making the adjustment of the headrest 100 more convenient.

[0049] Combination Figure 2 , Figure 4 and Figure 5 As shown, the locking member 23 is movably mounted on the frame member 21. The main body member 22 is provided with a first locking groove 221. The locking member 23 is provided with a locking block 231. The locking block 231 is located below the first locking groove 221 and selectively locks with the first locking groove 221. When the unlocking member 24 and the connecting rod 30 are disengaged, the unlocking member 24 drives the locking block 231 to move downward so that the locking block 231 is disengaged from the first locking groove 221.

[0050] Specifically, while the locking member 23 is disposed on the frame member 21, the locking member 23 can move up and down relative to the frame member 21. A locking block 231 is disposed on the lower side of the locking member 23, and a first locking groove 221 is disposed on the bottom of the main body member 22, and the locking block 231 is located on the lower side of the first locking groove 221.

[0051] When the locking member 23 moves upward, the locking block 231 moves upward into the interior of the first locking groove 221, and the locking block 231 locks into the first locking groove 221, so that the locking member 23 restricts the main body member 22 from moving in the front-back direction, thereby preventing the main body member 22 from moving relative to the skeleton member 21 in the front-back direction.

[0052] When the locking member 23 moves down, the locking block 231 moves down to disengage from the first locking groove 221. In this way, the movement of the main body 22 in the front-back direction is unrestricted, thereby enabling the main body 22 to move back and forth relative to the frame member 21. This allows the main body 22 to drive the outer cover 10 to move back and forth together, thereby adjusting the front-back position of the headrest 100.

[0053] Furthermore, while the unlocking member 24 is disengaged from the connecting rod 30, the unlocking member 24 can drive the locking block 231 on the locking member 23 to move downward, so that the locking block 231 on the locking member 23 is disengaged from the first locking groove 221 on the main body 22. In this way, the front and rear positions of the headrest 100 can be adjusted when the unlocking member 24 is disengaged from the connecting rod 30.

[0054] Combination Figures 4-6 As shown, the locking block 231 is provided with a first pressing block portion 233, and the unlocking member 24 is provided with a second pressing block portion 241. The unlocking member 24 can move in the left and right direction relative to the frame member 21, so that the second pressing block portion 241 selectively presses down on the first pressing block portion 233. Specifically, in the embodiment of this utility model, the part of the second pressing block portion 241 on the unlocking member 24 that cooperates with the first pressing block portion 233 on the locking block 231 is an inclined slope 2411, and the inclined surface 2411 on the second pressing block portion 241 is a downward inclined surface 2411 from right to left.

[0055] During the left-right movement of the unlocking member 24 relative to the frame member 21, when the second pressing block 241 moves to the left, the contact position between the inclined surface 2411 on the second pressing block 241 and the first pressing block 233 gradually moves downward on the inclined surface 2411. This allows the second pressing block 241 to press the first pressing block 233 downward, thereby driving the locking block 231 to move downward. This allows the locking block 231 to disengage from the first locking block, so that the main body 22 is disengaged from the locking member 23. This allows the main body 22 to move relative to the frame member 21 in the front-back direction, thereby adjusting the front-back position of the headrest 100.

[0056] When the second pressing block 241 moves to the right, the contact position between the inclined surface 2411 on the second pressing block 241 and the first pressing block 233 gradually moves upward on the inclined surface 2411. This allows the first pressing block 233 to reset upward, so that the locking block 231 can re-lock into the first locking groove 221. This can fix the front and rear position of the main body 22 relative to the frame 21, ensuring the reliability of the headrest 100's support for the head.

[0057] Combination Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the locking block 231 has a first pressing block 233 on both sides in the front and rear directions. The unlocking member 24 has two second pressing blocks 241 spaced apart in the front and rear directions on the corresponding parts of each locking block 231. The two first pressing blocks 233 and the two second pressing blocks 241 correspond one-to-one. This arrangement ensures the force balance between the unlocking member 24 and the locking block 231 in the front and rear directions when the unlocking member 24 presses down on the locking block 231. This also ensures the stability of the locking member 23 in the vertical direction. This arrangement ensures the stability of the locking block and the first locking groove 221 in locking and unlocking operation, thereby helping to avoid jamming during the operation of the adjusting component 20.

[0058] Combination Figure 2 , Figure 3 and Figure 4 As shown, the skeleton member 21 is provided with a limiting groove 211, and the unlocking member 24 is provided with a limiting piece 242. The limiting piece 242 extends into the limiting groove 211 and can move in the left and right directions relative to the limiting groove 211. Specifically, in the embodiment of this utility model, the unlocking member 24 is located below the skeleton member 21. The front end of the skeleton member 21 is provided with a limiting groove 211 near the unlocking member 24, and the front end of the unlocking member 24 is provided with a limiting piece 242. The limiting groove 211 extends in the left and right directions, and the dimension of the limiting groove 211 in the left and right directions is larger than the dimension of the limiting piece 242 in the left and right directions.

[0059] With this configuration, when the limiting piece 242 extends into the limiting groove 211, the rear side of the skeleton member 21 and the front side of the unlocking member 24 are engaged in a limiting fit in the front-back direction. This ensures the structural stability of the unlocking member 24 relative to the skeleton member 21 in the front-back direction. The limiting piece 242 can move left and right in the limiting groove 211, thereby enabling the unlocking member 24 to move left and right relative to the skeleton member 21. This allows the unlocking member 24 to selectively disengage from the connecting rod 30 and enables the unlocking member 24 to drive the locking member 23 to selectively disengage from the main body member 22.

[0060] Combination Figure 4 and Figure 6 As shown, the headrest 100 of the vehicle also includes a first reset elastic element 40, which is disposed between the unlocking member 24 and the frame member 21, so as to drive the unlocking member 24 to reset after the external force on the unlocking member 24 is removed. Specifically, the first reset elastic element 40 has a certain elastic deformation capability, can be compressed, and reset through its own elastic potential energy after being compressed.

[0061] Furthermore, one end of the first reset elastic member 40 is connected to the unlocking member 24, and the other end is connected to the frame member 21. Thus, when the unlocking member 24 moves to the right relative to the frame member 21, the first reset elastic member 40 is compressed, and its internal elastic potential energy increases. When the external force on the unlocking member 24 is removed, the first reset elastic member 40 pushes the unlocking member 24 to the left under the action of its own elastic potential energy, so as to drive the second pressing block 241 to the left. This not only releases the downward pressure exerted by the second pressing block 241 on the first pressing block 233, so that the locking block 231 can be reset upward, but also resets the unlocking member 24, so that the unlocking member 24 can be pushed to the right during the next adjustment of the headrest 100.

[0062] In the embodiments of this utility model, combined with Figure 6 and Figure 7 As shown, the unlocking member 24 is provided with a first cross rib 244. One end of the first reset elastic member 40 is fitted on the outside of the first cross rib 244, and the other end abuts against the skeleton member 21. This arrangement can ensure the reliability of the setting of the first reset elastic member 40 between the skeleton member 21 and the unlocking member 24, and can prevent the first reset elastic member 40 from jumping out of the set position when compressed.

[0063] Combination Figure 2 and Figure 8 As shown, the locking member 23 includes a frame 232 and a locking block 231. The frame 232 is movably mounted on the skeleton member 21, and the locking block 231 is located at the lower end of the frame 232.

[0064] Specifically, a limit frame 213 is provided on the skeleton component 21, and a positioning clip 214 is provided on the left and right sides of the limit frame 213. The frame 232 of the locking component 23 is movably set in the limit frame 213, and the positioning clip 214 and the frame 232 are engaged in the upper limit in the front-back direction. This can ensure that the position of the locking component 23 is fixed in the front-back direction, and can ensure the smoothness of the up-down movement of the locking component 23, thereby preventing the adjustment component 20 from getting stuck.

[0065] Furthermore, the upper end of the frame 232 selectively engages with the upper end of the limiting frame 213, and the lower end of the frame 232 of the locking member 23 selectively engages with the lower end of the limiting frame 213. In this way, when the frame 232 moves up and down relative to the limiting frame 213, the limiting frame 213 can limit the movement of the frame 232 in the vertical direction. This not only enables the selective locking engagement between the locking block 231 and the first locking groove 221, but also ensures the stability of the locking member 23 in the skeleton member 21, thereby ensuring the structural stability and operational reliability of the adjustment component 20.

[0066] Furthermore, a second reset elastic member 50 is provided between the frame 232 and the skeleton member 21. When the unlocking member 24 moves to the right, so that the second pressing block 241 presses down the first pressing block 233, the second reset elastic member 50 is stretched, and its internal elastic potential energy increases. When the external force on the unlocking member 24 is removed, that is, after the second pressing block 241 on the unlocking member 24 removes the downward pressure on the first pressing block 233 on the locking block 231, the second reset elastic member 50 pushes the locking member 23 upward under the action of its elastic potential energy, so as to drive the locking member 23 to reset. In this way, the locking block 231 can be locked again with the first locking groove 221 on the main body member 22, thereby fixing the position of the headrest 100 in the front-back direction, so as to fix the position of the headrest 100. In the embodiments of this utility model, the locking member 23 is provided with second cross ribs 234 on the left and right sides, and there are two second reset elastic members 50. One end of the second reset elastic member 50 is sleeved on the outside of the second cross rib 234, and the other end abuts against the skeleton member 21. This arrangement can ensure the reliability of the second reset elastic member 50 between the skeleton member 21 and the locking member 23, and can prevent the second reset elastic member 50 from jumping out of the set position when compressed.

[0067] Combination Figure 2 and Figure 9 As shown, there are multiple first locking grooves 221, which are arranged sequentially in the front-rear direction of the main body 22. The locking block 231 selectively locks with one of the multiple first locking grooves 221. With this configuration, when the main body 22 moves back and forth relative to the frame 21, one of the multiple first locking grooves 221 can correspond to the locking block 231 on the locking member 23. In this way, after the headrest 100 is adjusted to the appropriate position, the locking reliability between the locking member 23 and the main body 22 can be guaranteed, thereby ensuring the reliability of the headrest 100 in the current position. With this configuration, this embodiment of the utility model can not only realize the adjustment of the front-rear position of the headrest 100, but also ensure the reliability of the headrest 100 in supporting the head.

[0068] Combination Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the unlocking member 24 is provided with a first through hole 243, and a locking piece 2431 is provided on one side of the first through hole 243. The connecting rod 30 is provided with a second locking groove 31. The connecting rod 30 passes through the first through hole 243, and the locking piece 2431 and the second locking groove 31 selectively lock. Specifically, in the embodiment of this utility model, at least two connecting rods 30 are connected between the frame member 21 and the seat back of the vehicle. The two connecting rods 30 are spaced apart from each other. The unlocking member 24 is provided with two first through holes 243 spaced apart from each other from the left and right, so that the two connecting rods 30 can pass through the outer cover member 10 and the unlocking member 24 and are both connected to the frame member 21.

[0069] Furthermore, the diameter of the first through hole 243 is larger than the radial dimension of the connecting rod 30, and a locking piece 2431 is provided in the first through hole 243. The locking piece 2431 can selectively lock into the second locking groove 31 on the connecting rod 30. With this configuration, when the unlocking member 24 is disengaged from the connecting rod 30, the frame member 21 can move vertically relative to the connecting rod 30 to adjust the vertical position of the headrest 100. After the vertical height of the headrest 100 is adjusted, the unlocking member 24 locks into the connecting rod 30 to fix the headrest 100 in the current position. The locking configuration of the locking piece 2431 and the second locking groove 31 ensures the reliability of the vertical position of the headrest 100.

[0070] Combination Figure 5 and Figure 6 As shown, there are multiple second locking grooves 31, which are arranged sequentially in the vertical direction of the connecting rod 30. The locking piece 2431 selectively locks with one of the multiple second locking grooves 31. With this configuration, when the headrest 100 moves up and down relative to the connecting rod 30, the locking piece 2431 in the first through hole 243 can correspond to one of the multiple second locking grooves 31 on the connecting rod 30. After the headrest 100 is adjusted to a suitable position, the external force on the unlocking member 24 can be removed. The unlocking member 24 is reset under the action of the first reset elastic member 40, so that the locking piece 2431 locks with the second locking groove 31 on the connecting rod 30 when the headrest 100 is in its current position. This can fix the headrest 100 in its current position to ensure the reliability of the headrest 100 after the vertical position adjustment.

[0071] Combination Figure 11 As shown, the outer cover 10 is provided with a second through hole 124, through which the connecting rod 30 passes. The second through hole 124 extends in the front-back direction to avoid the connecting rod 30 when the outer cover 10 moves back and forth with the main body 22. Specifically, the outer cover 10 and the main body 22 are connected to form a whole. When the main body 22 moves back and forth relative to the frame 21, the outer cover 10 also needs to move synchronously in the front-back direction with the main body 22 to adjust the front-back position of the headrest 100 relative to the connecting rod 30.

[0072] Furthermore, the second perforation 124 extends in the front-back direction, which allows the outer cover 10 to have a certain amount of movement space relative to the connecting rod 30 in the front-back direction, while avoiding the connecting rod 30. In this way, the reliability of the headrest 100's front-back square movement can be guaranteed.

[0073] In the embodiments of this utility model, combined with Figure 10 and Figure 11 As shown, the outer cover 10 includes a front cover 11 and a rear cover 12. The front cover 11 includes a first faceplate 111, a foam component 112, and a foam support plate 113. The first faceplate 111 has snap-fit ​​fasteners sewn around its perimeter. During assembly, the fasteners are simply snapped onto the snaps around the perimeter of the foam support plate 113. The back of the foam support plate 113 has multiple threaded holes, and the front end of the main body 22 has multiple screw mounting holes 223. The multiple threaded structures correspond one-to-one with the multiple screw mounting holes 223, so that the front cover 11 can be connected to the main body 22 with screws.

[0074] Furthermore, the rear cover 12 consists of a cover body 121, a second cover 122, and a metal clip 123. The second cover 122 is attached to the cover body 121. The metal clip 123 is installed at the bottom inside the cover body 121 to connect the main body 22. With this arrangement, the front cover 11, the main body 22, and the rear cover 12 form a whole.

[0075] Furthermore, the rear cover 12 is provided with an unlocking button 125, which corresponds to one end of the unlocking member 24 in the left and right directions. This way, by pressing the unlocking button 125, the unlocking member 24 can be pushed to move left and right, thereby allowing the unlocking member 24 to disengage from the connecting rod 30 and drive the locking member 23 to disengage from the main body 22.

[0076] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the main body 22 is provided with a guide protrusion 222, and the skeleton 21 is provided with a guide groove 212. The guide protrusion 222 extends into the guide groove 212, and the inner wall of the guide groove 212 is provided with a guide rib 2121. The guide rib 2121 and the guide protrusion 222 guide and cooperate with each other in the front and rear directions.

[0077] Specifically, the main body 22 and the skeleton 21 are installed together by the cooperation of the guide protrusion 222 and the guide groove 212, and the guide protrusion 222 extends into the guide groove 212. The cooperation of the guide protrusion 222 and the guide groove 212 can ensure the installation accuracy of the main body 22 and the skeleton 21, and can avoid the incorrect installation direction of the main body 22 on the skeleton 21. This can improve the installation efficiency of the adjustment component 20 and help improve the assembly efficiency of the vehicle.

[0078] Furthermore, the guide groove 212 has guide ribs extending in the front-to-back direction. The guide ribs and guide protrusions 222 guide and cooperate in the front-to-back direction. This ensures the smooth movement of the main body 22 when it moves relative to the skeleton 21 in the front-to-back direction. On the other hand, after the first locking groove 221 and the locking block 231 lock together, it can prevent the main body 22 and the skeleton 21 from having a wobbling gap due to the draft angle. Thus, the structural stability of the adjustment assembly 20 can be guaranteed.

[0079] Combination Figure 2 and Figure 6 As shown, a bushing 60 is fitted onto the upper end of the connecting rod 30, and a groove for the bushing 60 is provided inside the skeleton member 21. The bushing 60 is installed in the groove of the bushing 60, and the upper end of the connecting rod 30 extends into the skeleton member 21. The bushing 60 and the skeleton member 21 are buffered together. This can prevent the upper end of the connecting rod 30 from shaking due to the draft angle after it extends into the skeleton member 21. With this setting, when the unlocking member 24 drives the skeleton member 21 to move up and down relative to the connecting rod 30, and when the locking piece 2431 locks into the second locking groove 31, the stability of the headrest 100 on the connecting rod 30 can be improved.

[0080] According to an embodiment of the present invention, a vehicle may include a headrest 100. When the headrest 100 of the present invention is unlocked by the unlocking member 24 and the connecting rod 30, the unlocking member 24 can drive the locking member 23 to disengage from the main body member 22. This not only allows the main body member 22 to move back and forth relative to the frame member 21, but also allows the frame member 21 to move up and down relative to the connecting rod 30. This allows the headrest 100 to be adjusted in both the back-and-forth and up-and-down directions at the same time, thereby making the adjustment of the headrest 100 position in the vehicle more convenient.
