Description
Technical Field
[0001] This application relates to the technical field of headrests, in particular to a manually six-way adjustable sleep headrest. Background Art
[0002] A six-way adjustable headrest is a design of a car seat headrest that allows the headrest to be adjusted in six directions to meet the head and neck needs of different users and provide a more comfortable and personalized riding experience. This design usually includes height adjustment, angle adjustment, and possibly lateral adjustment of the headrest to ensure that the occupant can obtain the best comfort and support during long drives or naps in the car.
[0003] However, the existing six-way headrest has a complex structure during adjustment. Especially during front-back adjustment, due to the relatively small internal space of the headrest, the operation is relatively complicated. Therefore, this application proposes a manually six-way adjustable sleep headrest that is convenient for front-back adjustment. Utility Model Content
[0004] The purpose of this application is to propose a manually six-way adjustable sleep headrest.
[0005] To achieve the above purpose, the technical solution adopted in this application is: a manually six-way adjustable sleep headrest, including a first adjustment structure and a locking component. The first adjustment structure includes a front-back slider and a front-back adjustment block. The front-back adjustment block and the locking component are guided by an inclined plane. In the natural state, the front-back adjustment block cooperates with the front-back slider to lock. When the locking component is pressed, the front-back adjustment block moves directionally to release the lock of the front-back slider. The front-back adjustment block is provided with a first elastic reset member, and the first elastic reset member makes the front-back adjustment block cooperate with the front-back slider to lock in the initial state.
[0006] Preferably, the locking component includes an unlocking slider. A first inclined plane is provided in the middle section of the unlocking slider, and a second inclined plane is provided on the front-back adjustment block. When the locking component moves in the pressing direction, the first inclined plane acts on the second inclined plane to make the front-back adjustment block descend, and then release the lock with the front-back slider. A multi-gear clamping groove is provided at the bottom of the front-back slider, and the top of the front-back adjustment block is a clamping portion. When the locking component is pressed, the front-back adjustment block descends to compress the first elastic reset member, and the corresponding clamping portion and the clamping groove are disengaged.
[0007] As a preference, this manual six-way adjustable sleep headrest further includes a front cover, an intermediate baffle, and a rear shell. A metal clip and a clamping portion are provided between the intermediate baffle and the rear shell for clamping connection; the front cover and the rear shell are locked by screws; the locking assembly further includes an adjustment button assembly, the adjustment button assembly is slidably arranged on the rear shell, the adjustment button assembly includes a button spring and an unlocking button, and the button spring elastically holds the unlocking button in the initial position.
[0008] As a preference, a second elastic reset member is provided between the unlocking slider and the intermediate baffle, and the second elastic reset member makes the unlocking slider abut against the unlocking button in the initial state; when the unlocking button is pressed, the second elastic reset member deforms accordingly, and at the same time, the first inclined surface and the second inclined surface interact to release the locking state of the front and rear adjustment blocks. At this time, front and rear adjustment can be performed. After adjustment, the unlocking button is released, and the second elastic reset member resets to make the unlocking slider return to its original position. At this time, the first inclined surface and the second inclined surface return to the initial state, and correspondingly, the first elastic reset member acts to lock the front and rear adjustment blocks against the front and rear sliders.
[0009] As a preference, it further includes a wing flip structure and side pads. The wing flip structure includes a fixing plate in the middle and wing covers hinged and installed on both sides through rotation shafts; the side pads are angle-adjusted as the wing covers rotate; the rotation shafts are provided with damping structures; the side pads include a foamed inner plate and an outer face cover. The foamed inner plate is provided with indentations corresponding to the connection positions of the fixing plate and the wing covers on both sides, and the outer face cover forms wings on both sides.
[0010] As a preference, the first adjustment structure further includes a headrest guide rod and a headrest guide sleeve for restricting the up and down movement of the headrest guide rod. In the initial state, the first elastic reset member makes the unlocking slider closely abut against the side of the intermediate baffle close to the button, so as to form a concave-convex fit between the headrest guide rod and the unlocking slider. When the unlocking button is pressed to move the unlocking slider, the cooperation between the headrest guide rod and the unlocking slider is cancelled.
[0011] As a preference, the headrest guide sleeve includes a limiting portion protruding outward, the intermediate baffle includes a limiting groove, the width of the limiting groove is greater than that of the limiting portion, and the bottom of the limiting portion abuts against the inner bottom surface of the limiting groove.
[0012] As a preference, the headrest guide rod is formed with a concave surface, and the unlocking slider is formed with a convex surface. In the initial state, the first elastic reset member makes the convex surface of the unlocking slider closely adhere to the concave surface to form a fit.
[0013] As an optimization, the adjustment width of the clamping groove is 20 - 60 millimeters.
[0014] As an optimization, the adjustment height of the headrest guide rod is 40 - 80 millimeters.
[0015] Compared with the prior art, the beneficial effects of this application are as follows:
[0016] In this application, when the locking component is pressed, the front and rear adjustment blocks move in a guiding manner to release the locking of the front and rear sliders. At this time, the front and rear sliders are unlocked, so front and rear adjustment can be performed. After the adjustment, the button is released, and the front and rear adjustment blocks are reset by the first elastic reset member to restore the locking of the front and rear sliders, thereby completing the adjustment. The front and rear adjustment method is simple, and stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment:
[0031] Referring to Figures 1 to 7 , this embodiment provides a manually six-way adjustable sleep headrest, including a first adjustment structure and a locking component. The first adjustment structure includes a front-back slider 8 and a front-back adjustment block 11. The front-back adjustment block 11 and the locking component are guided by an inclined plane. The front-back adjustment block 11 is provided with a first elastic reset member 10. In the initial state, the first elastic reset member 10 makes the front-back adjustment block 11 cooperate with the front-back slider 8 to lock. When the locking component is pressed, the front-back adjustment block 11 moves in a guided manner to release the locking of the front-back slider 8. At this time, the front-back slider 8 is unlocked, so front-back adjustment can be performed. After the adjustment, the button is released, and the front-back adjustment block 11 is reset by the first elastic reset member 10 to restore the locking of the front-back slider 8, thereby completing the adjustment.
[0032] As shown in the figure, the locking assembly includes an unlocking slider 6. A first inclined surface 14 is provided in the middle section of the unlocking slider 6, and a second inclined surface 14 is provided on the front and rear adjusting block 11. When the locking assembly moves in the pressing direction, the first inclined surface 14 acts on the second inclined surface 14 to cause the front and rear adjusting block 11 to descend, thereby unlocking it from the front and rear sliders 8. Multiple-gear clamping grooves are provided at the bottom of the front and rear sliders 8, and the top of the front and rear adjusting block 11 is a clamping portion. When the locking assembly is pressed, the front and rear adjusting block 11 descends to compress the first elastic reset member 10, and the corresponding clamping portion and the clamping groove are disengaged. Through the interaction between the first inclined surface 14 and the second inclined surface 14, when the unlocking slider 6 is pressed to the right as shown in the figure, the front and rear adjusting block 11 is guided to move downward accordingly, so as to unlock from the front and rear sliders 8. At this time, front and rear adjustment can be performed. After the adjustment, when released, the first elastic reset member 10 resets to cause the front and rear adjusting block 11 to move upward and form a lock with the front and rear sliders 8, thus completing the adjustment. It can be seen that even if the unlocking slider 6 does not separately provide the second elastic reset member 9, the reset function of the first elastic reset member 10 can also ensure the locking function.
[0033] Referring to Figure 1 , Figure 2 and Figure 6 , this manual six-way adjustable sleeping headrest further includes a front cover, an intermediate baffle 5 and a rear shell 2. A metal clip 7 and a clamping portion are provided between the intermediate baffle 5 and the rear shell 2 for clamping; the front cover and the rear shell 2 are locked by screws. The front cover is the outer face sleeve 1 and its internal foamed inner plate and the wing flipping structure; the locking assembly further includes an adjustment button assembly. The adjustment button assembly is slidably arranged on the rear shell 2. The adjustment button assembly includes a button spring and an unlocking button 3. The button spring elastically holds the unlocking button 3 in the initial position. The unlocking button 3 can be pressed towards the unlocking slider 6 side. The unlocking button 3 itself is provided with a button spring and remains in the initial state when not pressed.
[0034] Installing the unlocking button 3 on the rear shell 2 facilitates the operation of the unlocking button and also avoids the soft fit between the unlocking button 3 and the foamed inner plate and the outer face sleeve 1, making the appearance of the headrest assembly full and coordinated.
[0035] Referring to Figure 3 , a second elastic reset member 9 is provided between the unlocking slider 6 and the intermediate baffle 5. The second elastic reset member 9 makes the unlocking slider 6 abut against the unlocking button 3 in the initial state; when the unlocking button 3 is pressed, the second elastic reset member 9 deforms accordingly. At the same time, the first inclined surface 14 and the second inclined surface 14 interact to release the locked state of the front and rear adjusting block 11. At this time, front and rear adjustment can be performed. After the adjustment, when the unlocking button 3 is released, the second elastic reset member 9 resets to cause the unlocking slider 6 to return to its original position. At this time, the first inclined surface 14 and the second inclined surface 14 return to the initial state, and correspondingly, the first elastic reset member 10 acts to cause the front and rear adjusting block 11 to form a lock with the front and rear sliders 8.
[0036] Both the first elastic reset member 10 and the second elastic reset member 9 can be set as springs.
[0037] Referring to Figure 6 , this sleep headrest further includes a wing flip structure and a side cushion. The wing flip structure includes a fixed plate 16 in the middle and wing cover plates 17 hinged on both sides through a rotating shaft 18; the side cushion adjusts its angle as the wing cover plate 17 rotates; the rotating shaft 18 is provided with a damping structure; the side cushion includes a foamed inner plate and an outer face cover 1. The foamed inner plate is provided with indentations corresponding to the joints of the fixed plate 16 and the wing cover plates 17 on both sides, and the outer face cover 1 forms wings on both sides. The angles of the two wing cover plates 17 can be adjusted through the wing flip structure, so that the outer face cover 1 deforms to adapt to the user's head. The second adjustment structure in this embodiment is jointly composed of the wing flip structure and the corresponding foamed inner plate and outer face cover 1. When the passenger flips the wings on both sides of the headrest, the comfortable angle position required for the flipping of the two wings can be achieved.
[0038] Referring to Figure 4 , Figure 5 and Figure 8 , the first adjustment structure further includes a headrest guide rod 4 and a headrest guide sleeve 19 for restricting the up and down movement of the headrest guide rod 4. In the initial state, the first elastic reset member makes the unlocking slider 6 close to the side of the middle baffle 5 near the button, so that an uneven fit is formed between the headrest guide rod 4 and the unlocking slider 6. When the unlocking button 3 is pressed to move the unlocking slider 6, the cooperation between the headrest guide rod 4 and the unlocking slider 6 is cancelled. Thus, six-way adjustment can be achieved through the settings of the first adjustment structure and the second adjustment structure. Of course, what is given in this embodiment is only an optional embodiment, and existing other similar functional solutions may also be directly applied to this solution to form a new solution.
[0039] To facilitate the fixation of the headrest guide sleeve 19, referring to Figure 3 as shown, the headrest guide sleeve 19 includes a limiting portion 12 protruding outward. The middle baffle 5 includes a limiting groove. The width of the limiting groove is greater than that of the limiting portion 12, and the bottom of the limiting portion 12 abuts against the inner bottom surface of the limiting groove. Figure 3 It can be seen that the width of the limiting groove where the limiting portion 12 is located is relatively large, so the headrest guide sleeve itself does not interfere with the unlocking slider 6 when the unlocking slider 6 moves.
[0040] To facilitate the formation of a locking fit between the headrest guide rod 4 and the unlocking slider 6, as Figure 8 shown, the headrest guide rod 4 is formed with a concave surface 13, and the unlocking slider 6 is formed with a convex surface 20. In the initial state, the convex surface 20 of the unlocking slider 6 tightly abuts against the concave surface 13 of the headrest guide rod 4 under the action of the first elastic reset member 10 to form a fit.
[0041] Among them, the adjustable width of the clamping groove is 20 to 60 millimeters, and the adjustable height of the headrest guide rod 4 is 40 to 80 millimeters. If the adjustable range is too small, it has little practical significance. If the adjustable range is too large, it will occupy too much space and thus is not practical.
[0042] The basic principle, main features and advantages of the present application have been described above. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
