Description

Technical Field

[0001] This utility model relates to the field of neck pillow technology, specifically to a height-adjustable neck pillow. Background Technology

[0002] Neck pillows are widely used travel, office, and rest products. Their main function is to provide support for the user's neck, relieve neck muscle fatigue, and improve comfort, especially in scenarios such as long-distance travel and office lunch breaks. An ideal neck pillow should effectively conform to the physiological curve of the neck and the contour of the shoulders of different users, providing stable and even support.

[0003] Currently, most mainstream neck pillows on the market, regardless of whether they use memory foam, air filling, granular filling, or other materials and structures, generally suffer from a significant technical flaw: fixed size. This fixed size limits their adaptability to different usage scenarios. For example, when a user's sitting posture (upright, slightly reclining) and backrest angle are different, the required support angle and height for the neck may also need to be slightly adjusted, and a fixed-size neck pillow cannot meet this dynamic need. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the height of neck supports cannot be adjusted in the existing technology by providing a height-adjustable neck pillow.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a height-adjustable neck pillow, comprising:

[0006] Slow rebound braces are made of elastically deformable materials; (when compressed, they slowly conform to the cervical spine and slowly return to their original shape when the pressure is removed).

[0007] A height-adjustable support component is disposed inside the slow-rebound support body and is used to adjust the support height of the slow-rebound support body for the neck;

[0008] An elastic fabric is wrapped around the outside of the slow rebound support to constrain the deformation of the slow rebound support and provide a contact surface.

[0009] Furthermore, the slow rebound support body is provided with an installation slot in the middle that is adapted to the height-adjustable support assembly.

[0010] Furthermore, the height-adjustable support assembly includes a support portion and an adjustment drive portion; the adjustment drive portion acts on the support portion, causing the support portion to move relative to the slow-rebound support body, thereby causing the slow-rebound support body to undergo controllable deformation to adjust its support height for the neck.

[0011] Furthermore, the support portion includes:

[0012] pallet;

[0013] Two sliding sleeves are fixedly installed on opposite sides of the tray, respectively;

[0014] A threaded sleeve is fixedly installed in the middle area of ​​the tray.

[0015] Furthermore, the adjustment drive unit includes:

[0016] Base;

[0017] The mounting plate is fixedly installed on one side of the base.

[0018] A knob is rotatably mounted within the mounting plate;

[0019] One end of the screw is fixedly connected to the knob, and the other end passes through the base and is threaded into the threaded sleeve.

[0020] Two sliding rods are fixedly installed on opposite sides of the base and slide in cooperation with the sliding sleeve.

[0021] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0022] The height-adjustable support assembly enables precise and controllable mechanical height adjustment. Simply rotate the knob to drive the screw, causing the support plate to rise and fall smoothly. The design of the slide rod and sleeve ensures a stable, smooth, and non-deviation-prone adjustment process. Once adjusted to the correct position, the threaded self-locking feature provides a stable support height that will not change unexpectedly due to pressure during use. Users can adjust the support height in real time and precisely according to the current usage scenario and their personal comfort preferences to obtain truly personalized neck support.

[0023] When a user tries to look down at a phone or book, this neck brace provides upward support, physically supporting the chin or jawbone area, significantly increasing resistance to looking down and actively intervening to effectively prevent cervical spine damage caused by poor posture such as looking down at a phone or book for a long time.

[0031] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a height-adjustable neck pillow, which includes:

[0032] The slow rebound support 1 is made of an elastically deformable material, and has a mounting slot 11 in the middle that is adapted to the height-adjustable support component 2. In this embodiment, the slow rebound support 1 is memory foam. When the slow rebound support 1 is compressed, it will slowly conform to the cervical spine, and when the pressure is removed, it will slowly return to its original shape.

[0033] A height-adjustable support assembly 2 is disposed inside the slow-rebound support body 1 and is used to adjust the support height of the slow-rebound support body 1 for the neck. The height-adjustable support assembly 2 includes a support part 21 and an adjustment drive part 22. The adjustment drive part 22 acts on the support part 21, causing the support part 21 to move relative to the slow-rebound support body 1, thereby causing the slow-rebound support body 1 to undergo controllable deformation to adjust its support height for the neck.

[0034] Elastic fabric 3 covers the exterior of the slow rebound support 1, constraining its deformation and providing a contact surface. It not only provides a skin-friendly and breathable contact surface but also effectively constrains the deformation range of the slow rebound support 1, ensuring it maintains its ideal shape during adjustment and support, preventing excessive expansion or collapse.

[0035] The specific support part 21 includes:

[0036] Pallet 211;

[0037] Two sliding sleeves 212 are respectively fixedly disposed on opposite sides of the support plate 211;

[0038] The threaded sleeve 213 is fixedly installed in the middle area of ​​the support plate 211.

[0039] The specific adjustment drive unit 22 includes:

[0040] Base plate 221;

[0041] Mounting plate 222 is fixedly mounted on one side of the base 221;

[0042] The knob 223 is rotatably mounted within the mounting plate 222;

[0043] The screw 224 has one end fixedly connected to the knob 223, and the other end passes through the base 221 and is threadedly engaged with the threaded sleeve 213.

[0044] Two sliding rods 225 are fixedly installed on opposite sides of the base 221 and slide in cooperation with the sliding sleeve 212.

[0045] The working principle of this utility model:

[0046] 1. Initial state:

[0047] When the neck pillow is in an unadjusted state, the slow rebound support 1 maintains its original shape and height.

[0048] The height-adjustable support assembly 2 is integrated into the slow-rebound support body 1. The base 221 and mounting plate 222 of the adjustment drive unit 22 are fixed, the knob 223 is in the initial position, the screw 224 is fully screwed into the threaded sleeve 213, the support plate 211 is positioned rearward and close to the base 221, and the sliding sleeve 212 is located at the end of the sliding rod 225 close to the base 221.

[0049] 2. Adjust the height (to increase support):

[0050] When users need to increase the neck support height of the neck pillow, rotate knob 223 clockwise.

[0051] The knob 223 drives the screw 224, which is fixedly connected to it, to rotate synchronously.

[0052] The screw 224 and the threaded sleeve 213 fixed on the support plate 211 form a threaded pair. The rotational motion of the screw 224 is converted into the linear motion of the support plate 211 through the threaded sleeve 213.

[0053] The tray 211 moves away from the base tray 221 and the mounting plate 222 in the direction of linear motion.

[0054] The sliding sleeves 212 fixed on both sides of the tray 211 slide along the sliding rods 225 fixed on both sides of the base 221 to ensure that the movement trajectory of the tray 211 is straight and stable, and to prevent it from rotating or deviating.

[0055] The support plate 211, which moves forward (away from the base 221, usually toward the neck), begins to push against the material of the slow-rebound support 1 in front of it.

[0056] The material of the slow-rebound support 1 is subjected to the pushing force of the support plate 211, resulting in a controlled and slow deformation. The material is squeezed and bulges upward.

[0057] This deformation causes the surface of the elastic fabric 3 covering the slow-rebound support 1 to bulge, increasing the height and support of the contact area between the neck pillow and the neck.

[0058] The user continues to rotate knob 223 until the desired support height is achieved. The slow-rebound material's properties allow it to gradually conform to the shape formed by the push of the support plate 211 during deformation.

[0059] 3. Adjust the height (lower the support):

[0060] When the user needs to lower the neck pillow height, rotate knob 223 counterclockwise.

[0061] Knob 223 drives screw 224 to rotate in the opposite direction.

[0062] The threaded engagement between the screw 224 and the threaded sleeve 213 converts the rotational motion of the screw 224 into the linear motion of the support plate 211 (and the entire support part 21) toward the base support 221.

[0063] The pallet 211 moves back closer to the base plate 221.

[0064] The sliding sleeve 212 slides along the sliding rod 225 toward the bottom support 221, continuing to guide the support plate 211 to move smoothly in a straight line.

[0065] As the pallet 211 moves backward, its pushing force on the material of the forward slow-rebound support 1 decreases or is released.

[0066] The slow-rebound support material, due to its inherent elasticity and slow-rebound properties, begins to slowly recover from the compressed and bulged shape to its original state or a lower height shape.

[0067] The elastic fabric 3 wrapped around it also slowly shrinks back, reducing the height of the neck pillow's contact surface and its support strength.

[0068] The user continues to rotate knob 223 in the opposite direction until the desired lower support height is reached or the device is fully restored to its initial state.

[0069] 4. Usage status:

[0070] After adjustment, knob 223 stops rotating, and the self-locking action of screw 224 and threaded sleeve 213 (usually designed with self-locking threads, such as ordinary triangular threads) firmly locks the support plate 211 in the current position.

[0071] The cooperation between the slide bar 225 and the slide sleeve 212 further stabilizes the position of the support plate 211, preventing it from shaking or moving accidentally.

[0072] The slow-rebound support 1, pushed to a specific shape by the support plate 211, maintains the adjusted height and shape under its own elasticity and fabric constraint, providing stable support for the neck.

[0073] The user's neck rests on the slow-rebound support 1 covered by elastic fabric 3. The slow-rebound material undergoes further slow micro-deformation according to the pressure applied to the neck (this is a characteristic of its material) to distribute the pressure more evenly, conform to the curve of the cervical spine, and provide comfortable support. When the head is lifted (pressure removed), the slow-rebound material slowly returns to the adjusted shape supported by the support plate 211.

[0074] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
