Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, specifically to an adjustable neck massage mechanism. Background Technology

[0002] With rapid economic development, people's work and life pace is getting faster and faster, and work pressure is also increasing, leading to a continuous rise in the incidence of cervical spondylosis. Currently, massage is the most common method of treating cervical spondylosis in China, resulting in the emergence of various neck massagers on the market.

[0003] A common type of neck massager includes a shell, a massage mechanism, a motor to drive the massage mechanism, and massage heads mounted on the massage mechanism. There are two sets of massage heads. The massage mechanism is mounted on the shell. When in use, the shell is worn around the neck, allowing the massage heads to contact the neck. The neck is positioned between the two sets of massage heads. The motor drives the massage mechanism to rotate, which in turn causes the massage heads to swing and perform kneading motions, achieving a relaxing effect on the neck.

[0004] Regarding the aforementioned technical conditions, there is also the issue that, due to the different neck widths of each person, a single-width massage head is no longer suitable for different groups of people.

[0005] Based on this, the present invention designs an adjustable neck massage mechanism to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable neck massage mechanism, comprising a housing, a massage mechanism mounted on the housing, and a motor for driving the mechanism. The massage mechanism includes a drive gear, a rotating shaft, and a moving block. The moving block has a moving groove with an internal thread. The rotating shaft has a thread that matches the moving groove. A connecting ring is fixedly mounted on the moving block and is inclined. A swing ring is mounted on the rotating shaft and is sleeved on the connecting ring. An anti-detachment ring is rotatably mounted on the rotating shaft and is fixedly connected to the connecting ring. The massage head is fixedly mounted on the swing ring. A limit block is fixedly mounted on the swing ring. A limit groove is formed on the housing, and the limit block is located in the limit groove. A damper is fixedly mounted in the swing ring and abuts against the connecting ring. A first stop is fixedly mounted on one end of the rotating shaft, and a second stop is mounted on the other end. When the moving block contacts the first stop, the connecting ring rotates relative to the damper.

[0007] By adopting the above technical solution, when adjusting the width, the drive motor drives the drive gear to rotate. At this time, the rotating shaft rotates, and under the damping, the connecting ring does not rotate. Simultaneously, the moving slot is threaded onto the rotating shaft, thereby driving the moving block to move outward. When the anti-detachment ring contacts the second stop, the movement of the moving block is restricted, and the connecting ring rotates relative to the damping. When adjusting the narrowness, the drive motor drives the drive gear to rotate. Under the damping, the moving block moves inward. When the moving block contacts the first stop, the movement of the moving block is restricted, and the connecting ring rotates relative to the damping, thus achieving the effect of adjusting the width of the massage head.

[0008] Preferably, the movable block is provided with an eccentric block, the eccentric block is fitted with an installation ring, the installation ring is fixedly provided with a connecting plate, the outer shell is fixedly provided with a guide rod, the connecting plate is provided with a guide groove, the guide rod is located in the guide groove, and the connecting plate is fixedly provided with a massage block.

[0009] By adopting the above technical solution, when the moving block rotates, it drives the eccentric block to rotate, thereby driving the mounting ring to swing, which in turn drives the massage block to swing and massage, thereby increasing the massage area and improving the massage effect.

[0010] Preferably, a contact block is fixedly provided in the movable groove, and the side wall of the first stop block abuts against the contact block.

[0011] By adopting the above technical solution, the first stop block abuts against the moving block and the contact block at the same time, further restricting the movement of the moving block, while more fully driving the moving block to rotate.

[0012] Preferably, a hemispherical block is fixedly provided on the limiting block.

[0013] By adopting the above technical solution, when the limiting block moves, the hemispherical block reduces the contact area with the limiting groove, thereby reducing friction.

[0014] Preferably, the massage head includes a protrusion and a recess, with two protrusions and the recess located between the two protrusions, and the protrusions being spherical.

[0015] By adopting the above technical solution, the two protrusions increase the contact area with the neck during massage, thereby improving the massage effect.

[0016] Preferably, the massage block is a spherical block.

[0017] By adopting the above technical solution, the spherical massage blocks can avoid the appearance of protruding edges during massage, thus improving massage comfort.

[0018] Preferably, the massage block is made of silicone.

[0019] By adopting the above technical solutions, the cushioning during massage is improved and hard contact is reduced, thereby enhancing massage comfort.

[0020] In summary, this application has the following beneficial technical effects: When adjusting the width, the drive motor drives the drive gear to rotate, and the rotating shaft rotates. Under the damping, the connecting ring does not rotate, and the moving slot is threaded onto the rotating shaft, thereby driving the moving block to move outward. When the anti-detachment ring contacts the second stop, the movement of the moving block is restricted, and the connecting ring rotates relative to the damping. When adjusting the narrowness, the drive motor drives the drive gear to rotate, and under the damping, the moving block moves inward. When the moving block contacts the first stop, the movement of the moving block is restricted, and the connecting ring rotates relative to the damping, thus achieving the effect of adjusting the width of the massage head.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] Reference Figures 1-7 An adjustable neck massage mechanism includes a housing 1, a massage mechanism mounted on the housing 1, and a motor 2 for driving the mechanism. The motor 2 is a servo motor. The massage mechanism includes a drive gear 3, a rotating shaft 4, and a moving block 5. A connecting shaft 6 is rotatably mounted on the housing 1. A connecting transmission gear 8 and a connecting gear 7 are coaxially fixed on the connecting shaft 6. A worm gear 9 is coaxially fixed on the rotating shaft of the drive motor 2. The worm gear 9 meshes with the transmission gear 8, and the connecting gear 7 meshes with the drive gear 3. One end of the rotating shaft 4 is rotatably mounted on the housing 1, and the other end is coaxially fixed to the drive gear 3. The drive motor 2 and the worm gear 9 drive the transmission gear 8 to rotate, and the connecting gear 7 follows the rotation of the transmission gear 8, thereby driving the drive gear 3 to rotate.

[0027] Reference Figures 1-7The movable block 5 has a movable groove 10 with an internal thread. The rotating shaft 4 has a thread that matches the movable groove 10. A connecting ring 11 is fixedly mounted on the movable block 5 and is inclined. A swing ring 12 is mounted on the rotating shaft 4 and is sleeved on the connecting ring 11. An anti-detachment ring 13 is rotatably mounted on the rotating shaft 4 and is fixedly connected to the connecting ring 11. The massage head is fixedly mounted on the swing ring 12. A limit block 14 is fixedly mounted on the swing ring 12. A limit groove 15 is provided on the outer shell 1, and the limit block 14 is located in the limit groove 15. A damper 16 is fixedly mounted in the swing ring 12. In this embodiment, the damper 16 is ring-shaped and is sleeved on the connecting ring 11. The damper 16 abuts against the connecting ring 11. The anti-detachment ring 13 blocks the swing ring 12 to prevent it from detaching from the connecting ring 11. Reference Figures 1-7 A first stop 17 is fixedly installed on one end of the rotating shaft 4, close to the motor 2. A second stop 18 is installed on the other end of the rotating shaft 4. During width adjustment, the drive motor 2 drives the drive gear 3 to rotate. At this time, the rotating shaft 4 rotates. Because the limiting groove 15 blocks the limiting block 14, it prevents the swing ring 12 from rotating. Under the pressure of the damping 16, the connecting ring 11 cannot rotate. The moving groove 10 is threadedly connected to the rotating shaft 4. As the rotating shaft 4 rotates continuously, it drives... The moving block 5 moves away from the first stop 17 away from the motor 2; when the anti-detachment ring 13 contacts the second stop 18, the second stop 18 restricts the movement of the moving block 5. Since the friction of the damper 16 reaches its upper limit, it can no longer fix the connecting ring 11, allowing the connecting ring 11 to rotate relative to the damper 16, thus allowing the entire moving block 5 to rotate; since the connecting ring 11 is tilted, the connecting ring 11 rotates eccentrically on the rotating shaft 4, contacting the swing ring 12 to swing, allowing the massage head to swing and massage. Reference Figures 1-7 When the width is adjusted, the drive motor 2 drives the drive gear 3 to rotate in the opposite direction. Under the pressure of the damper 16, the moving block 5 moves towards the first stop 17. When the moving block 5 contacts the first stop 17, the movement of the moving block 5 is restricted. The connecting ring 11 rotates relative to the damper 16, allowing the moving block 5 to rotate with the rotating shaft 4, thereby achieving the effect of adjusting the width of the massage head.

[0028] An eccentric block 19 is provided on the movable block 5, and an installation ring 20 is fitted on the eccentric block 19. A connecting plate 21 is fixedly installed on the installation ring 20, and a guide rod 22 is fixedly installed on the outer shell 1. A guide groove 23 is opened on the connecting plate 21, and the guide rod 22 is located in the guide groove 23. A massage block 24 is fixedly installed on the connecting plate 21. When the movable block 5 rotates, it drives the eccentric block 19 to rotate, thereby driving the installation ring 20 to swing. The guide rod 22 is located in the guide groove 23, which guides the swing direction of the connecting plate 21, driving the massage block 24 to swing and massage, increasing the massage area, and thus improving the massage effect.

[0029] Reference Figures 1-7 A contact block 25 is fixedly provided in the moving groove 10. When the first stop block 17 abuts against the moving block 5, the side wall of the first stop block 17 abuts against the contact block 25 at the same time as the first stop block 17 abuts against the moving block 5, further restricting the movement of the moving block 5, and at the same time driving the moving block 5 to rotate more fully.

[0030] Reference Figures 1-7 The massage head includes a raised portion 26 and a recessed portion 27. There are two raised portions 26, and the recessed portion 27 is located between the two raised portions 26. The raised portions 26 are spherical. During massage, the two raised portions 26 increase the contact area with the neck and improve the massage effect. At the same time, the spherical raised portions 26 improve the comfort of the massage.

[0031] Reference Figures 1-7 In this embodiment, the massage block 24 is a spherical block made of silicone. During massage, the spherical massage block 24 can avoid the appearance of protrusions, thus improving massage comfort. At the same time, the silicone massage block 24 improves the cushioning during massage, reduces hard contact, and further enhances the massage comfort effect.

[0032] Reference Figures 1-7 A hemispherical block 28 is fixedly provided on the limiting block 14. When the moving block 5 moves and drives the limiting block 14 to move, the hemispherical block 28 reduces the contact area with the limiting groove 15, thereby reducing friction.

[0033] The implementation principle of this embodiment is as follows: When adjusting the width, the drive motor 2 causes the moving block 5 to move away from the first stop block 17. When adjusting the narrowness, the drive motor 2 drives the drive gear 3 to rotate in the opposite direction. Under the pressure of the damping 16, the moving block 5 moves towards the first stop block 17. When the moving block 5 contacts the first stop block 17, the movement of the moving block 5 is restricted. The connecting ring 11 rotates relative to the damping 16, allowing the moving block 5 to rotate with the rotating shaft 4, thereby achieving the effect of adjusting the width of the massage head.
