Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a small, manually adjustable, two-way neck pillow. Background Technology

[0002] With continuous industrial development and a significant improvement in people's living standards, automobiles have become increasingly integrated into people's daily lives and work. Due to the natural curves of the human body, when the head rests on a headrest, the neck is often unsupported, which can easily lead to neck stiffness and other discomfort over time. To effectively protect and support the neck, a neck pillow is usually installed on the headrest bar between the headrest and the backrest.

[0003] Most neck pillows on the market today are made of memory foam, shaped to conform to the curve of the neck, covered with a cover, and finally secured to the headrest rod with straps. Although existing neck pillows can provide some support for the neck, they have obvious shortcomings. On the one hand, their materials are too soft and lack support; on the other hand, they cannot be adjusted in height or back and forth relative to the headrest, so they cannot conform well to the neck when meeting the needs of different people. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned problems by providing a small, manually adjustable, two-way neck pillow. This neck pillow has an internal neck pillow frame assembly that provides strong support. The frame assembly also includes an unlocking mechanism; pressing the unlock button separates the mechanism from the slot, allowing for three adjustable positions in the forward and backward direction. Furthermore, a support plate and a pin secure the neck pillow to the headrest rod, allowing the pillow to adjust up and down along with the headrest. This not only improves the neck pillow's support but also allows for adjustments to suit different users' needs, ensuring a better fit to the neck.

[0005] To achieve the above objectives, this utility model provides a small, manually adjustable, two-way neck pillow, including a guide rod, a neck pillow housing assembly, a support plate, an unlocking structure, and an unlocking button. The head of the guide rod has an outwardly protruding boss, and the guide rod is provided with multiple slots that cooperate with the unlocking structure for gear adjustment. The tail of the guide rod passes through the neck pillow housing assembly and is connected to the support plate. The neck pillow housing assembly is provided with an unlocking structure that cooperates with the slots. An unlocking button is provided on one side of the neck pillow housing assembly that allows the unlocking structure to move. When the unlocking structure is separated from the slots, the neck pillow housing assembly can move back and forth relative to the guide rod.

[0026] like Figure 11 and 12 As shown, this application employs an innovative structural design. When the headrest 9 is in its lowest position, an adjustable neck pillow is cleverly designed within the narrow space between the headrest 9 and the seat back 10. For support, the neck pillow has a neck pillow frame assembly inside the neck pillow housing assembly 2, with an aluminum alloy support plate 3 behind it. The combination of the neck pillow frame assembly and the support plate 3 provides reliable support for the neck pillow, ensuring its stability under the pressure of the passenger's head and preventing deformation or breakage. For adjustment, the user simply presses the unlock button 4 to move the unlocking mechanism inside the neck pillow housing assembly 2. When the unlocking mechanism separates from the guide rod, the neck pillow can be adjusted to three positions (forward and backward). Furthermore, the entire neck pillow is securely connected to the headrest rod 11 via the support plate 3 and the second pin 8. This connection allows the neck pillow to adjust up and down along with the headrest 9. Through this design, the neck pillow can be precisely adjusted to meet the needs of different users, ensuring a better fit to the neck and effectively improving seating comfort and neck support.

[0027] like Figures 1-2 As shown, a small, manually adjustable, two-way neck pillow includes a guide rod 1, a neck pillow housing assembly 2, a support plate 3, an unlocking structure 4, and an unlocking button 5. Figure 10As shown, the head of the guide rod 1 has an outwardly protruding boss 101. The boss 101 is used to cooperate with the first limiting arm 2119 and the second limiting arm 21113 on the neck pillow housing assembly 2 to limit the maximum distance that the neck pillow housing assembly 2 and its internal structure can move forward relative to the guide rod 1. The guide rod 1 is provided with three slots 102 that cooperate with the unlocking structure 4 for gear adjustment. The tail of the guide rod 1 passes through the neck pillow housing assembly 2 and is connected to the support plate 3. The entire neck pillow is connected to the headrest rod through the support plate 3. The neck pillow housing assembly 2 is provided with an unlocking structure 4 that cooperates with the slots 102. The neck pillow housing assembly 2 on one side of the unlocking structure 4 is provided with an unlocking button 5 that can move the unlocking structure 4 left and right. When the unlocking button 5 is pressed to separate the unlocking structure 4 from the slots 102, the neck pillow housing assembly 2 is moved to adjust the unlocking structure 4 to engage in different slots 102, so as to adjust the forward and backward movement of the neck pillow in three gears.

[0028] like Figure 2 and Figure 6 As shown, the neck pillow shell assembly 2 includes a neck pillow frame assembly 201, foam 202, and a cover 203. The neck pillow frame assembly 201 consists of a frame 211, an upper cover plate 212, and a lower cover plate 213. The front side of the frame 211 is a contoured curved surface 2111 designed according to the curve of the human neck. The middle of the contoured curved surface 2111 has a connecting plate 2112 perpendicularly connected to it. An unlocking structure 4 is installed on the connecting plate 2112. The top of the frame 211 is snapped with the upper cover plate 212 designed according to the curve of the lower part of the headrest, and the bottom of the frame 211 is snapped with the lower cover plate 213 designed according to the curve of the top of the seat back. The upper cover plate 212 and the lower cover plate 213 are snapped with the frame 211 to form a... The inner cavity for installing the unlocking structure 4 allows the neck pillow to fit better in the narrow space between the headrest and the seat back when the headrest is in its lowest position, thanks to the curved surfaces of the upper cover plate 212 and the lower cover plate 213. An unlocking button 5 is snapped onto the frame 211 on one side of the unlocking structure 4. Pressing the unlocking button 5 can move the unlocking structure 4 left and right on the connecting plate 2112. An aluminum alloy support plate 3 is provided on the rear side of the frame 211, which can provide X-axis support for the neck pillow frame assembly 201. The frame 211 is covered with foam 202. The frame 211 covered with foam 202, the upper cover plate 212 and the lower cover plate 213 snapped onto the frame 211 are all covered with a skin 203.

[0029] like Figure 7As shown, the frame 211 includes a contoured curved surface 2111 that conforms to the neck. The top, left and right sides, and bottom of the contoured curved surface 2111 all have inwardly extending first flanges 2113 that follow the shape of the upper and lower cover plates. The rear side of the connecting plate 2112 has a second flange 2114 extending upward and downward. The first flange 2113 and the second flange 2114 are integrally connected to form mounting holes 2115 for installing the upper and lower cover plates. The left side of the first flange 2113 has a button mounting hole 2116. The contoured curved surface 2111... The second flange 2114, opposite to the guide rod, has a first guide rod mounting hole 2117 at a position relative to the guide rod. The connecting plate 2112 has a first clearance hole 2118 at a position relative to the first guide rod mounting hole 2117. The guide rod passes through the first guide rod mounting hole 2117 and the first clearance hole 2118 and is connected to the support plate by a second pin. The middle part of the connecting plate 2112 has, from left to right, two upwardly extending first limiting arms 2119, a downwardly recessed first clearance lifting groove 21110, and two upwardly extending middle limiting arms.

[0030] 21111, a downwardly recessed second clearance lifting groove 21112 and two upwardly extending second limiting arms 21113, the two first limiting arms 2119 and the two second limiting arms 21113 have the same structure and are all located at the top of the first clearance hole 2118. The boss at the head of the guide rod cooperates with the first limiting arm 2119 and the second limiting arm 21113 to limit the maximum distance that the neck pillow frame assembly 201 can move forward relative to the guide rod. The first clearance lifting groove 21110 and the second clearance lifting groove 21112 have the same structure, such as... Figure 4 and Figure 7 As shown, one side of the bottom of the groove is a clearance opening 21114 for the unlocking structure 4. The middle part of the bottom of the groove has upward-extending baffles 21115 on both sides. The bottom between the two baffles 21115 has an upward-inclined lifting surface 21116. The other side of the bottom of the groove is provided with an upward-extending first claw 21117. The steel wire in the unlocking structure 4 can be restricted in the X and Z directions by the baffles 21115 on both sides, the bottom of the groove and the first claw 21117. The lifting surface 21116 can also lift and lower the steel wire 401 when it moves left and right in the Y direction. There is a second clearance hole between the two middle limiting arms 21111. The connecting plate 2112 has positioning holes 21118 and locking holes 21119 around its perimeter to position with the upper cover plate and the lower cover plate.

[0031] like Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, the unlocking structure 4 includes a steel wire 401 and a tension spring 402 for resetting the steel wire 401. The steel wire 401 has a downwardly bent unlocking section 411 on one side opposite the unlocking button 5, which cooperates with the unlocking button 5. The other side of the unlocking section 411 consists of a first locking section 412, a first lifting section 413, a limiting section 414, a second lifting section 415, and a second locking section 416, in sequence. The first locking section 412 and the second locking section 416 of the steel wire 401 are respectively locked onto two... Between a limiting arm 2119 and two second limiting arms 21113, the steel wire 401 is limited in the X direction. Simultaneously, the steel wire 401 is engaged with the slot 102 on the guide rod 1 via a first engaging section 412 and a second engaging section 416. The first lifting section 413 and the second lifting section 415 of the steel wire 401 are formed by bending the steel wire downwards and then lifting it upwards, respectively engaging in the first clearance lifting groove 21110 and the second clearance lifting groove 21112. The first lifting section... 413 and the second lifting section 415 limit the X-direction of the steel wire 401 by avoiding the baffles 21115 on both sides of the lifting groove, and limit the Z-direction of the steel wire 401 by avoiding the bottom of the lifting groove and the first claw 21117. Through the cooperation of the lifting surface 21116 and the lifting section, the steel wire 401 moves in the Y-direction and is lifted in the Z-direction, so that the first limiting arm 2119 and the second limiting arm 21113 on the steel wire 401 separate from the claw 102 on the guide rod 1, thereby releasing the wire. The locking mechanism includes a U-shaped limiting section 414 of the steel wire 401 formed by bending the steel wire downwards. The limiting section 414 passes through the second clearance hole and is engaged between the two central limiting arms 21111 to prevent the steel wire 401 from flipping or rotating during lateral movement. The first lifting section 413 and the second lifting section 415 of the steel wire 401 are respectively connected to one end of two tension springs 402. The other end of the tension springs 402 is connected to the lower cover plate 213. The tension springs 402 are used to quickly reset the steel wire 401.

[0032] like Figure 6 As shown, the upper cover plate 212 includes an upper cover plate body 2121, which is a curved surface similar to the lower curve of the headrest. The bottom of the cover plate body 2121 has a first positioning post 2122 and a second claw 2123 that engages with the frame 211. The lower cover plate 213 includes a lower cover plate body 2131, which is a curved surface similar to the top curve of the seat back. The top of the lower cover plate body 2131 has a second positioning post 2132, a hook part 2133 connected to the tension spring 402, and a third claw 2134 that engages with the frame 211.

[0033] As a further optimization, a metal clip 6 is provided in the slot of the frame 211. The second claw 2123 on the upper cover plate 212 and the third claw 2134 on the lower cover plate 213 are engaged with the slot of the frame 211 by the metal clip 6. The metal clip 6 can prevent the upper cover plate 212 and the lower cover plate 213 from being directly engaged with the frame 211 and causing breakage.

[0034] like Figure 5 and Figure 9 As shown, the support plate 3 is made of aluminum alloy to prevent deformation or breakage when the neck of the human body applies pressure to the neck pillow. The support plate 3 has a second guide rod mounting hole 31 on the side near the neck pillow housing assembly. The inner wall of the second guide rod mounting hole 31 has a plurality of first limiting ribs 311 that cooperate with the guide rod. The first limiting ribs 311 limit the radial direction of the guide rod. At the same time, when the guide rod is assembled with the second guide rod mounting hole 31, the tolerance of the second guide rod mounting hole 31 can be improved by the collapse of the plurality of first limiting ribs 311, which facilitates the installation of the guide rod. The support plate 3 has a first pin connecting hole 32 that is perpendicular to the second guide rod mounting hole 31 at the position relative to the second guide rod mounting hole 31. After the guide rod passes through the first guide rod mounting hole, the first clearance hole on the frame and the second guide rod mounting hole 31 on the support plate 3, the neck pillow housing assembly is connected to the support plate 3 by inserting the first pin 7 into the first pin connecting hole 32. The support plate 3 has a headrest rod mounting hole 33 on one side opposite the headrest rod, which mates with the headrest rod. The arc-shaped sidewall of the headrest rod mounting hole 33 near the neck pillow housing assembly has multiple second limiting ribs 331 that abut against the headrest rod. The support plates 3 on both sides of the headrest rod mounting hole 33 have second pin connection holes 34 that connect to the headrest rod. The second pin 8 passes through the second pin connection hole 34 and the through hole on the headrest rod, allowing the entire neck pillow to be connected to the headrest rod via the support plate 3. When the entire neck pillow moves up and down with the headrest rod, because the second limiting ribs 331 abut against the headrest rod, the entire neck pillow is not affected by gravity and rotates downwards around the second pin 8, only adjusting up and down with the headrest rod. When you want to remove the neck pillow, simply pull out the second pin 8 to remove the entire neck pillow from the headrest rod.

[0035] Adjusting the working process

[0036] The neck pillow in this application can be adjusted to three positions (forward and backward) and to different heights. When adjusting forward and backward, the unlocking button 5 needs to be pressed to move the steel wire 401 in the unlocking structure 4. During the movement, the steel wire 401 cooperates with the lifting surface on the frame through the lifting section, so that the steel wire 401 is lifted in the Z direction during the lateral movement, so that the locking sections at both ends of the steel wire 401 are separated from the locking groove 102 in the guide rod 1, thereby achieving the purpose of unlocking. At this time, the neck pillow housing assembly 2 can be moved forward and backward relative to the guide rod 1 and the support plate 3 according to the needs of the driver and passenger. When adjusting the height, only the height of the headrest rod needs to be adjusted, so that the entire neck pillow can move with the headrest rod.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
