Description

Technical Field

[0001] This utility model relates to the field of driving and riding products technology, and in particular to a detachable and adjustable neck support device. Background Technology

[0002] With the increasing popularity of cars, people mostly travel by car, which significantly increases the time users spend in their vehicles, especially on long journeys. Therefore, the demand for comfortable seating and health protection is also rising. Ordinary seats cannot fully conform to the curves of the human body, easily leading to fatigue problems such as neck stiffness and lower back pain over time, and even affecting health. To better support the user's head when sitting, users often add a backrest at the headrest support. This backrest closely conforms to the head and neck, relieving spinal pressure and maintaining correct posture.

[0003] Currently, most car seat headrest devices on the market have design flaws. Their neck pillow components are tightly connected to the device, lacking a convenient disassembly mechanism. This forces users to remove the entire device from the car seat to clean the neck pillow, which is not only time-consuming and laborious but also quite cumbersome. Secondly, it greatly limits users' personalized choices, preventing them from changing to different styles and materials of neck pillows according to their personal preferences. Furthermore, for manufacturers, the difficulty in disassembly and assembly necessitates packaging the entire device, increasing packaging costs.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0019] As a further embodiment of this utility model: a rotation adjustment mechanism is provided between the mounting column and the neck pillow, and the neck pillow can be adjusted at multiple angles through the rotation adjustment mechanism;

[0020] The rotating adjustment mechanism includes a rotating sleeve rotatably mounted at one end of the mounting column and a locking member mounted on the rotating sleeve and the mounting column. The rotating sleeve is connected to the neck pillow, and the locking member is used to lock the rotating sleeve.

[0021] As a further embodiment of this utility model: the rotary adjustment mechanism further includes a first ring and a second ring disposed at one end of the mounting column, and the rotary sleeve is disposed between the first ring and the second ring. The inner wall of the first ring is uniformly provided with first teeth in a circumferential manner, and the inner wall of the rotary sleeve is uniformly provided with second teeth in a circumferential manner.

[0022] The locking component includes an adjusting gear, which is disposed in the first ring and the rotating sleeve. The adjusting gear meshes with the first tooth and the second tooth simultaneously. The adjusting gear can be pressed into the rotating sleeve so that it disengages from the first ring and fully enters the rotating sleeve. At this time, the rotating sleeve and the adjusting gear can rotate synchronously.

[0023] A third elastic element is provided between one end of the adjusting gear and the rotating sleeve. The third elastic element can push the adjusting gear to move by elastic force, so that the adjusting gear meshes with the first tooth.

[0026] One side of the frustum abuts against the baffle.

[0027] The baffle and the side end of the rotating sleeve form a concave platform structure. When the adjusting gear drives the truncated platform to reset, the two ends of the truncated platform are respectively fitted into the second ring and the concave platform structure.

[0028] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0029] 1. By moving the pusher, the movable block is displaced, allowing the lock to disengage from the lock groove, thus removing the neck pillow from the main body. When the mounting post is reinserted into the main body, the first elastic member can push the lock to engage with the lock groove, fixing the mounting post in the main body and completing the installation of the neck pillow. The mounting post has multiple lock grooves, allowing for multi-level adjustment of the neck pillow's front and back position.

[0030] The push head is cleverly designed into a cone shape, which then abuts against the inclined surface on the movable block to form a sliding fit. When the push rod is pushed, the push head and the inclined surface generate an interaction force. The lateral thrust of the push head on the inclined surface can be converted into the thrust of pressing down on the movable block, so that the locking block can be disengaged from the locking groove. This allows the push rod to be placed horizontally on the main body, and a button is set on the side of the main body instead of on the top of the main body. The side setting provides more operating space after the main body and the neck pillow are installed on the seat headrest, making it convenient for users to adjust the position of the neck pillow forward and backward, or to remove and install it.

[0031] Not only can the neck pillow be quickly assembled and disassembled, making it convenient for users to change the style of the neck pillow, but it also reduces the packaging volume and packaging costs. At the same time, it can realize multi-level adjustment of the front and back position of the neck pillow, so that the neck pillow can fit the neck of different users more closely and make the user experience more comfortable.

[0032] 2. The neck pillow connects to a rotating sleeve, allowing users to flexibly adjust its angle according to their posture, height, and neck curve. Once adjusted to a suitable angle, the rotating sleeve is fixed by a locking mechanism, ensuring a consistent neck pillow angle. This provides better support for the head and neck, enhancing user experience and comfort, reducing neck fatigue and pressure during long drives, and thus meeting the diverse needs of users with different body types and driving habits, offering greater adaptability.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-8 A detachable and adjustable neck support device includes a main body 1, a neck pillow 2, and a mounting column 3;

[0047] Mounting column 3 is slidably mounted on the main body 1.

[0048] The main body 1 is equipped with a locking adjustment mechanism 4;

[0049] The mounting post 3 has a locking groove 31, and the locking adjustment mechanism 4 includes a locking element 41 that is movably disposed in the main body 1, and the locking element 41 is engaged with the locking groove 31.

[0050] The locking adjustment mechanism 4 also includes a first elastic element 42 and a pushing element 5. The pushing element 5 is used to displace the movable block 411 and disengage the locking element 41 from the locking groove 31. The first elastic element 42 is used to push the locking element 41 to reset and engage with the locking groove 31.

[0051] Specifically, when the neck pillow 2 needs to be removed from the main body 1, the movement of the pusher 5 causes the movable block 411 to shift, thereby displacing the lock 41 from the locking groove 31 on the mounting post 3. At this point, the neck pillow 2 can be removed from the main body 1. As the lock 41 moves downward, it will also press against the first elastic member 42 at the lower end. When the mounting post 3 is reinserted into the main body 1, the first elastic member 42 can push the lock 41 upward, allowing the lock 41 to engage with the locking groove 31, thus securing the mounting post 3. The neck pillow 2 is fixed inside the main body 1, and the mounting post 3 is provided with multiple locking slots 31. When the locking member 41 is moved down by the pushing member 5 and the locking member 41 is disengaged from the currently engaged locking slot 31, the neck pillow 2 can be moved back and forth, allowing the mounting post 3 to slide back and forth inside the main body 1. After the front and back position of the neck pillow 2 is adjusted to a suitable position, the control of the pushing member 5 is released, and the first elastic member 42 pushes the locking member 41 up and engages with the corresponding locking slot 31, thus fixing the front and back position of the neck pillow 2.

[0052] Preferred, such as Figure 1 As shown, the main body 1 is provided with a clamping plate and fixing bolts. The clamping plate is fixedly connected to the main body by the fixing bolts and forms a clamping groove after being assembled with the main body. When the main body 1 is installed on the seat headrest, the main body and the clamping plate are assembled from the front and back of the seat headrest. The clamping groove formed after assembly clamps the support of the seat headrest. By tightening the fixing bolts, the clamping groove is fixed to the seat support, thereby fixing the main body. The clamping groove is also provided with anti-slip texture to prevent slippage.

[0053] Preferably, the locking element 41 includes a movable block 411 and a locking block 412;

[0054] The main body 1 is provided with an installation channel 11, and the movable block 411 is slidably disposed in the installation channel 11. The first elastic element 42 is disposed between the movable block 411 and the inner wall of the installation channel 11.

[0055] Specifically, such as Figure 1-5 As shown, an installation channel 11 is provided on the main body 1 for the mounting column 3 to slide back and forth. At the same time, a guide rail should be provided in the installation channel 11, and a corresponding guide groove is provided on the mounting column 3 so that the mounting column 3 can slide back and forth along the correct trajectory. The movable block 411 is slidably arranged in the installation channel 11, and a locking block 412 is formed at the upper end for engaging with the locking groove 31. The first elastic element 42 is arranged between the movable block 411 and the inner wall of the installation channel 11.

[0056] Preferably, the pusher 5 includes a push rod 51 disposed inside the main body 1. One end of the push rod 51 protrudes outside the main body 1, and the other end is provided with a push head 52. When the push rod 51 is pushed toward the movable block 411, the push head 52 will push the movable block 411 to move downward.

[0057] Specifically, such as Figure 1-5 As shown, during the disassembly and assembly of the neck pillow 2, the push rod 51 is pushed to move towards the movable block 411. During the movement of the push rod 51, the push head 52 pushes the movable block 411 downward, causing the locking block 412 to disengage from the locking groove 31. By pulling the push rod 51 outward, the push head 52 can be reset to release the restriction on the movable block 411, allowing the first elastic member 42 to push the movable block 411 upward, so that the locking block 412 can be re-engaged and fixed with the locking groove 31, thereby fixing the mounting post 3 and the neck pillow 2 in place.

[0058] Preferably, the push rod 51 is placed horizontally, the movable block 411 is provided with an inclined surface 413, and the push head 52 has a conical structure and abuts against the inclined surface 413 to form a positional fit relationship.

[0059] Specifically, such as Figure 1-5 As shown, the push head 52 is cleverly designed into a cone shape, and then it forms an abutment with the inclined surface 413 on the movable block 411 to form a sliding fit relationship. When the push rod 51 is pushed, the push head 52 and the inclined surface 413 generate an interaction force. When the push head 52 moves laterally, the lateral thrust on the inclined surface 413 can be converted into downward pressing force, so that the movable block 411 can move down in the installation channel 11, so that the locking block 412 can be disengaged from the locking groove 31. This allows the push rod 51 to be placed laterally on the main body 1, and a button 55 is set through the side end of the main body 1 instead of being set at the top of the main body 1. The side end setting can provide a larger operating space after the main body 1 and the neck pillow 2 are installed on the seat backrest, making it convenient for the user to adjust the front and back position of the neck pillow 2, or to disassemble it.

[0060] Preferably, the pusher 5 further includes a second elastic member 53 disposed within the main body 1, which can push the push rod 51 to move away from the movable block 411.

[0061] Specifically, such as Figure 1-5 As shown, the addition of a second elastic element 53 provides a thrust for the push rod 51 to move away from the movable block 411, so that when the button 55 is released, the push rod 51 and the push head 52 can automatically reset, further improving the ease of operation.

[0062] Preferably, the main body 1 has a sliding position 6 for placing the push rod 51 and a limiting groove 7. The second elastic member 53 is disposed in the limiting groove 7. The push rod 51 is provided with a limiting plate 54 located in the limiting groove 7. The second elastic member 53 can apply a force away from the movable block 411 to the limiting plate 54, so that the limiting plate 54 abuts against the groove wall of the limiting groove 7.

[0063] Specifically, such as Figure 1-5As shown, the sliding position 6 can restrict the movement of the push rod 51 to prevent it from tilting. The limiting groove 7 is connected to the sliding position 6. The limiting plate 54 set on the push rod 51 extends into the limiting groove 7. When the push rod 51 moves towards the movable block 411, causing the movable block 411 to move down, and then the mounting column 3 is removed or adjusted to the required position, the button 55 is released. The second elastic element 53 will push the limiting plate 54 to move in the opposite direction until the limiting plate 54 abuts against the groove wall of the limiting groove 7. At this time, the push head 52 will release the pushing force on the inclined surface 413, allowing the movable block 411 to move up and reset.

[0064] Preferably, the installation channel 11 is provided with a placement slot 111, the movable block 411 is placed in the placement slot 111, the placement slot 111 is provided with guide strips 112 on both sides inside, the movable block 411 is provided with guide grooves 414 on both sides, and the guide grooves 414 and guide strips 112 slide in cooperation.

[0065] The slot 111 has a through hole on one side that corresponds to the inclined surface 413, through which the pusher 52 passes.

[0066] Specifically, such as Figure 1-5 As shown, the width of the placement slot 111 should be consistent with that of the movable block 411. The movable block 411 is guided by the guide groove 414 on the side and the guide strip 112 in the placement slot 111 to achieve the guiding effect of moving up and down. This allows the force conversion between the push head 52 and the inclined plane 413 to be smoother and avoids the shaking of the movable block 411 during the movement.

[0067] In some embodiments, a rotation adjustment mechanism 8 is provided between the mounting column 3 and the neck pillow 2, and the neck pillow 2 can be adjusted at multiple angles through the rotation adjustment mechanism 8;

[0068] The rotary adjustment mechanism 8 includes a rotary sleeve 81 rotatably disposed at one end of the mounting post 3 and a locking member 82 disposed on the rotary sleeve 81 and the mounting post 3. The rotary sleeve 81 is connected to the neck pillow 2, and the locking member 82 is used to lock the rotary sleeve 81.

[0069] Specifically, such as Figure 1 and Figures 6-8 As shown, the neck pillow 2 is connected to the rotating sleeve 81, allowing users to flexibly adjust the angle of the neck pillow 2 according to their own sitting posture, height, neck curve and other needs. After adjusting to a suitable angle, the rotating sleeve 81 is fixed by the locking piece 82, so that the angle of the neck pillow 2 is fixed, which can provide more close support for the head and neck, improve the user's experience and comfort, reduce neck fatigue and pressure during long-term driving, and thus meet the differentiated needs of users with different body types and driving habits, with better adaptability.

[0070] Preferably, the rotary adjustment mechanism 8 further includes a first ring 83 and a second ring 84 disposed at one end of the mounting column 3, and a rotary sleeve 81 disposed between the first ring 83 and the second ring 84. The inner wall of the first ring 83 is uniformly provided with first teeth 85 around the circumference, and the inner wall of the rotary sleeve 81 is uniformly provided with second teeth 86 around the circumference.

[0071] The locking component 82 includes an adjusting gear 821, which is disposed in the first ring 83 and the rotating sleeve 81. The adjusting gear 821 simultaneously meshes with the first tooth 85 and the second tooth 86. The adjusting gear 821 can be pressed into the rotating sleeve 81, so that the adjusting gear 821 disengages from the first ring 83 and fully enters the rotating sleeve 81. At this time, the rotating sleeve 81 and the adjusting gear 821 can rotate synchronously.

[0072] A pressing element 823 is provided on one side of the adjusting gear 821, and the pressing element 823 protrudes out from the outside of the first ring 83;

[0073] A third elastic element 87 is provided between one end of the adjusting gear 821 and the rotating sleeve 81. The third elastic element 87 can push the adjusting gear 821 to move by elastic force, so that the adjusting gear 821 meshes with the first tooth 85.

[0074] Specifically, such as Figure 1 and Figures 6-8 As shown, the driver or passenger presses the adjusting gear 821 via the pressing element 823, causing the adjusting gear 821 to disengage from the first tooth 85 on the inner wall of the first ring 83 and fully engage with the second tooth 86 inside the rotating sleeve 81. At this time, the rotating sleeve 81 and the adjusting gear 821 can rotate synchronously. The rotating sleeve 81 is connected to the neck pillow 2, so its angle can be adjusted by rotating the neck pillow 2. After adjusting to a suitable angle, the pressure on the adjusting gear 821 is released, and the elastic restoring force of the third elastic element 87 is utilized. The adjusting gear 821 is pushed to move into the first ring 83, and the adjusting gear 821 returns to the state of simultaneously meshing with the first tooth 85 and the second tooth 86, thereby fixing the rotating sleeve 81 to the first ring 83, so that the position of the rotating sleeve 81 and the neck pillow 2 is fixed, preventing the angle of the neck pillow 2 from changing during use. In this utility model, the angle adjustment method of the neck pillow 2 has the effects of simple operation and quick adjustment. The user only needs to press and rotate to complete the adjustment of the angle of the neck pillow 2.

[0075] Preferably, a baffle 811 is provided inside the rotating sleeve 81 on the side near the second ring 84. The baffle 811 has a through hole, and the third elastic element 87 is provided between the adjusting gear 821 and the baffle 811.

[0076] A frustum 88 is provided inside the second ring 84, and a connecting rod 822 is provided on one side of the adjusting gear 821. The connecting rod 822 passes through the through hole on the baffle 811 and is fixedly connected to the frustum 88.

[0077] One side of the truncated cone 88 abuts against the baffle 811.

[0078] Specifically, such as Figure 1 and Figures 6-8 As shown, when the adjusting gear 821 is pressed, during the process of the adjusting gear 821 engaging with the second tooth 86 on the inner wall of the rotating sleeve 81, it not only compresses the third elastic element 87 between itself and the baffle 811, but also pushes the frustum 88 located in the second ring 84 through the connecting rod 822. When the neck pillow 2 is rotated, the rotating sleeve 81, the adjusting gear 821, the connecting rod 822, and the frustum 88 rotate synchronously and coaxially. When the pressing of the adjusting gear 821 is released, the third elastic element 87 pushes the adjusting gear 821 to reset. The adjusting gear 821 drives the frustum 88 on the other side to move through the connecting rod 822. When the frustum 88 abuts against the baffle 811 in the rotating sleeve 81, the adjusting gear 821 is in a state of simultaneously engaging with the first tooth 85 and the second tooth 86.

[0079] During assembly, the rotating sleeve 81 can be placed between the first ring 83 and the second ring 84, and then the frustum 88 can be placed inside the second ring 84. At this time, the adjusting gear 821 is pushed into the first ring 83, and the connecting rod 822 is fixed to the frustum 88 after passing through the through hole on the baffle 811. The frustum 88 plays a limiting role, which not only does not hinder the rotation of the adjusting gear 821 and the rotating sleeve 81, but also allows the baffle 811 to limit the adjustment gear 821 during the reset process, preventing the adjusting gear 821 from disengaging from the first ring 83 and the rotating sleeve 81. Furthermore, the connection of the frustum 88 on the other side makes the two ends more stable and balanced during rotation, thus making the rotation process smoother.

[0080] The baffle 811 and the side end of the rotating sleeve 81 form a recessed platform structure 812. When the adjusting gear 821 drives the truncated cone 88 to reset, the two ends of the truncated cone 88 are respectively fitted into the second ring 84 and the recessed platform structure 812, which can increase the stability of the rotating sleeve 81.

[0081] The third elastic element 87 is sleeved on the outside of the connecting rod 822. The third elastic element 87 is a spring. During assembly, the third elastic element 87 is first sleeved on the connecting rod 822, and then the connecting rod 822 is passed through the through hole on the baffle 811. The third elastic element 87 will be blocked by the baffle 811 and cannot pass through the through hole. During operation, the position of the rotating sleeve 81 is restricted by the first ring 83 and the second ring and is in a fixed state. Only the adjusting gear 821 moves laterally. Therefore, when the force of pressing the adjusting gear 821 is released, the third elastic element 87 will exert force on the other side with the baffle 811 as the fixed point, so that the thrust applied by the third elastic element 87 to the adjusting gear 821 is more concentrated, thereby making the reset movement of the adjusting gear 821 smoother.

[0082] Preferably, the first elastic element 42, the second elastic element 53, and the third elastic element 87 are all springs.

[0083] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
