Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cervical vertebrae health, more particularly to a neck traction device. BACKGROUND

[0002] In recent years, more and more attention has been paid to cervical vertebrae health. At present, there are various ways and devices for maintaining cervical vertebrae, for example, some cervical vertebrae physiotherapy devices stretch or relax the muscle groups of cervical vertebrae by pressing, rubbing, pinching, pushing, and pulling the cervical vertebrae to achieve the purpose of maintaining cervical vertebrae.

[0003] However, the existing cervical vertebrae physiotherapy devices mainly achieve the maintenance of cervical vertebrae by moving their local structures relative to the human body. Accordingly, many cervical vertebrae physiotherapy devices are provided with movable parts that move relative to the human body by rotating, lifting, translating, reciprocating, and vibrating. For example, the existing cervical vertebrae physiotherapy devices are usually provided with movable parts that can move upward and push the neck during the vertical upward movement of the movable parts. In order to achieve the preset movement mode of the movable part, the structural design of the cervical vertebrae physiotherapy device is relatively complex, which not only increases the manufacturing cost and difficulty, but also brings challenges to space utilization and control stability.

[0004] Some cervical vertebrae physiotherapy devices are designed with multiple movement modes, which are more complex in structure and manufacturing difficulty. For example, in order to achieve the movement of the movable part in different directions, some cervical vertebrae physiotherapy devices are provided with multiple drivers, multiple mounting tables, and multiple movement adjustment components. In order to achieve the coordination stability of different activities in different directions, the accuracy of each component itself and the structural coordination between each component are required to be high.

[0005] The applicant has been continuously researching and updating the cervical vertebrae health device. On January 12, 2024, the applicant submitted an invention patent application for a cervical vertebrae traction care device (application number: CN202410052387.9). On this basis, the applicant continues to research related products to improve product performance and make the cervical vertebrae health device more meet the needs of consumers and the market.

[0033] like Figures 1 to 4 As shown, a neck traction device according to a preferred embodiment of the present invention is illustrated. The neck traction device includes a headrest 10 and a base pad 20, wherein the base pad 20 is adapted to be placed on a surface of an object, wherein the headrest 10 is mounted on the base pad 20, and wherein the headrest 10 can be driven to rotate about a rotation axis L.

[0034] According to this preferred embodiment of the present invention, the base pad 20 has a built-in airbag, thereby driving the headrest to flip by inflating and deflating the airbag. Specifically, the neck traction device further includes a headrest flipping assembly 30, wherein the headrest flipping assembly 30 drives the headrest 10 to flip as a whole. The headrest flipping assembly 30 is placed at the bottom of the headrest 10 to drive the headrest 10 to flip.

[0035] Driven by the headrest tilting assembly 30, the headrest 10 tilts around the tilting axis L, wherein a fixed end 1001 of the headrest 10 is fixed relative to the bottom cushion 20 during the tilting of the headrest 10 around the tilting axis L. A neck traction end 1002 of the headrest 10 provides traction to the human neck supported thereon as the headrest 10 tilts, thereby generating traction to the human neck. During the resetting of the headrest 10 around the tilting axis L, the neck traction end 1002 of the headrest 10 gradually releases the traction to the human neck as the headrest 10 tilts back, thereby gradually releasing the traction to the human neck, in this way, the headrest 10 reciprocates, thereby providing traction health care to the human neck. The user can also choose to keep the tilting angle of the headrest 10 unchanged at a suitable traction force, so as to generate a preset intensity of continuous traction force.

[0036] According to the preferred embodiment of the present application, the headrest tilting assembly 30 is built-in the bottom cushion 20, wherein the bottom cushion 20 has a receiving cavity 201, and the headrest tilting assembly 30 is arranged in the receiving cavity 201.

[0037] The headrest tilting assembly 30 comprises a tilting air bag 31, wherein the tilting air bag 31 drives the headrest 10 to tilt when inflated and expanded, and drives the headrest 10 to reset when deflated and expanded.

[0038] When the neck traction device is placed on a support surface, the human body lies in a supine position, and the human head and neck are supported on the headrest 10, wherein the tilting air bag 31 is located on the lower side of the headrest 10, so that when the tilting air bag 31 is inflated and deformed, it further generates driving support force to the headrest 10, and drives the headrest 10 to tilt around the tilting axis L.

[0039] More specifically, the bottom cushion 20 is at least partially made of elastic material, so that when the air bag 31 is inflated and expanded, the corresponding part of the bottom cushion 20 is deformed, thereby enabling the expansion of the air bag 31 to drive the headrest 10 to tilt.

[0040] According to the preferred embodiment of the present application, the tilting air bag 31 expands towards the headrest 10 after being inflated, thereby driving the headrest 10 to tilt, and the position of the tilting air bag 31 away from the headrest 10 remains unchanged, thereby having higher efficiency of expansion and tilting driving. Specifically, the air bag 31 is supported on the surface of a hard object, so that the expansion and deformation is towards the headrest 10 under the support of the hard object.

[0041] According to the preferred embodiment of the utility model, the headrest overturning assembly 30 further comprises a support plate 32, wherein the support plate 32 is supported by hard material, so that the preset support degree can be provided for the overturning air bag 31, and the protection effect can be provided for the air bag.

The fixed end 311 is fixed to the support plate 32. The expansion body 312 is supported on the support plate 32, wherein the extension direction of the fixed end 311 is parallel to the overturning shaft L.

[0043] The bottom pad 20 comprises a pillow pad 21 and a shoulder pad 22, wherein the accommodating cavity 201 is formed in the pillow pad 21, and the shoulder pad 22 and the pillow pad 21 are fixed together. According to the preferred embodiment of the utility model, the pillow pad 21 and the shoulder pad 22 are integrally formed. When the user lies in a supine position, the head and neck of the user are supported on the headrest 10, wherein the shoulder of the user is placed on the shoulder pad 22 to generate pressure on the shoulder pad 22, preventing the shoulder pad 22 from moving, wherein the overturning air bag 31 placed in the accommodating cavity 201 formed in the pillow pad 21 is located at the lower side of the headrest 10, so that the overturning air bag 31 is deformed and expanded when inflated, and further generates driving support force on the headrest 10, and drives the headrest 10 to overturn around the overturning shaft L. At the same time, the shoulder pad 22 generates a certain positioning effect on the shoulder of the user, preventing the shoulder from moving with the overturning of the headrest 10, thereby ensuring the neck traction effect.

[0044] According to the preferred embodiment of the utility model, the neck traction device further comprises at least one support body 40 protruding from the surface of the bottom pad 20, the support body 40 extending between the bottom pad 20 and the headrest 10, for preventing the headrest 10 from moving a large position during movement.
