Description

Technical Field

[0001] The utility model relates to the technical field of massage cores, in particular to a massage core and a massage device with adjustable massage strength. Background Art

[0002] With the improvement of people's quality of life, the demand for personal care and relaxation is increasing. Massage devices, as effective tools for relieving fatigue, improving blood circulation, and relaxing the body and mind, have occupied a significant position in the market. However, the massage mechanisms in traditional massage devices often have a single function, unable to precisely adjust the intensity and location of the massage, making it difficult to meet the diverse needs of users. The stability of the massage device, especially during the massage process, is directly related to the comfort and effectiveness of the massage. Therefore, ensuring the stability of the massage device during rotation and movement has become a pressing technical challenge.

[0003] Existing massage mechanisms often employ simple mechanical structures to achieve the rotation and movement of the massage device, but these structures often struggle to ensure both stability and flexibility. For example, some massage mechanisms utilize sliding fits or pin connections to transmit power. However, these methods are prone to loosening and wear after prolonged use, causing the massage device's rotation axis to shift, thereby affecting the massage effect. Furthermore, since massage mechanisms typically include multiple massage devices, when the threaded sleeve intersects with the upper limit and enables the massage head to rotate with the threaded column to massage the massage area, without the support and connection of a connecting rod, a single massage device may experience rotational axis shift due to uneven force. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cable organizer that can be used as a bracket for electronic equipment.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A massage mechanism with adjustable massage intensity comprises a housing, a drive device, and two massage devices spaced apart from each other, each of the massage devices comprising a massage head, a threaded post fixed to the massage head, and a threaded sleeve sleeved on the threaded post. The two massage heads or the two threaded posts are connected as a whole by a connecting rod so that the two massage heads can move up and down synchronously. The threaded posts have an upper limit portion for limiting the upper limit position of relative movement of the threaded sleeve and the threaded post, and a lower limit portion for limiting the lower limit position of relative movement of the threaded sleeve and the threaded post.

[0007] In which, the driving device is connected to the threaded sleeve in a transmission manner to drive the threaded sleeve to rotate. When the massage head contacts the massage area, the threaded column and the threaded sleeve can move relative to each other along the axial direction of the threaded column to change the massage intensity by changing the height of the massage head. When the threaded sleeve conflicts with the upper limit portion or the lower limit portion, the massage head rotates with the threaded column to perform a massage action on the massage area.

[0008] Furthermore, the threaded sleeve is configured to rotate only around a set axis, and the threaded column cooperates with the threaded sleeve so that the threaded column rotates around the set axis or moves along the set axis.

[0009] Furthermore, the threaded column includes a mounting portion for fixedly connecting the massage head and a threaded portion threadably matched with the threaded sleeve, and the connecting rod is configured on the mounting portion.

[0010] Furthermore, the mating portion between the threaded portion and the threaded sleeve accounts for 1 / 3-2 / 3 of the thread length thereof, so as to increase the strength of the threaded mating between the threaded column and the threaded sleeve.

[0011] Furthermore, when the driving device drives the threaded sleeve and the threaded column to move relative to each other along a first direction, the massage head can be adjusted to a first massage depth; when the driving device drives the threaded sleeve and the threaded column to move relative to each other along a second direction, the massage head can be adjusted to a second massage depth.

[0012] Furthermore, the lower limit portion has a limit block, which is arranged at one axial end of the threaded column. When the massage head moves to the first position corresponding to the first massage depth, the limit block can abut against one end of the threaded sleeve to limit the threaded sleeve from continuing axial movement along the threaded column, thereby enabling the threaded sleeve to drive the massage head to rotate.

[0013] Furthermore, the upper limit portion is a radially protruding shoulder provided at one end of the threaded column away from the limit block. When the threaded column and the threaded sleeve move relative to each other to a second position corresponding to the second massage depth, the shoulder can abut against the other end of the threaded sleeve to axially limit the threaded sleeve, thereby enabling the threaded sleeve to drive the massage head to rotate.

[0014] Furthermore, the shell has an installation cavity, and the massage movement is configured in the installation cavity.

[0015] Furthermore, the driving device also includes a motor, and a transmission gear set is arranged between the motor and the threaded sleeve.

[0016] A massage device comprises the above-mentioned massage movement with adjustable massage intensity.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] 1. This utility model integrates two massage devices (including massage heads and threaded studs) through a connecting rod, enabling the two massage heads to move up and down synchronously. This design not only simplifies the mechanical structure but also ensures balanced and consistent massage force on both sides during the massage process. The connecting rod also effectively prevents individual massage devices from shifting or tilting due to uneven force, thereby ensuring the accuracy and stability of the massage action.

[0019] 2. In this utility model, when the threaded sleeve contacts the upper limit and the massage head rotates with the threaded column to massage the massage area, without the support and connection of the connecting rod, the rotation axis of a single massage device may shift due to uneven force. However, the connecting rod in this patent connects the two massage devices to form a stable structural framework, effectively preventing this shift. Even during high-intensity massage, the rotation axis of the massage device remains stable, thereby increasing the strength and durability of the massage device in the high-position state.

[0020] 3. By combining lifting and rotating modes, this patented massage head can simulate the effects of a human hand massage, providing a more comfortable and natural massage experience. Users can freely switch massage modes according to their personal preferences and needs, enjoying a personalized massage service. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0039] See also Figure 1-Figure 3The present utility model discloses a massage mechanism, which is primarily used in massage devices such as massage pillows, seat cushions, or massage chairs. In this embodiment, the massage mechanism comprises a housing 100, a drive device 300, and two massage devices 200. Each massage device 200 includes a massage head 230, a threaded post 220 secured to the massage head, and a threaded sleeve mounted on the threaded post 220 and capable of outputting rotational power. The housing 100 defines a mounting cavity 110, within which the massage mechanism is disposed. The drive device 300 includes a motor 310, with a transmission gear set 500 disposed between the motor 310 and the threaded sleeve. In this embodiment, the threaded sleeve is a drive gear 210. The drive gear 210 is configured to rotate only about a set axis. The massage devices 300 are threadedly engaged with the drive gear 210 to rotate about or move along the set axis. The two massage heads 230 or the two threaded posts 220 are connected as one body via a connecting rod 400, allowing the two massage heads to move up and down synchronously. The threaded posts 220 have an upper limit portion 221 for limiting the upper limit of relative movement between the threaded sleeve and the threaded post 220, and a lower limit portion 222 for limiting the lower limit of relative movement between the threaded sleeve and the threaded post. Specifically, the drive device 300 is in transmission connection with the drive gear 210 to drive the drive gear 210 to rotate. When the massage heads 230 contact the massage area, the threaded posts 220 and the drive gear 210 can move relative to each other along the axial direction of the threaded posts 220, thereby changing the massage intensity by changing the height of the massage heads 230. When the drive gear 210 contacts the upper limit portion 221 or the lower limit portion 222, the massage heads 230 rotate with the threaded posts 220 to massage the massage area.

[0040] It's important to note that since massage mechanisms typically feature multiple massage devices, when the threaded sleeve contacts the upper limit, allowing the massage head to rotate with the threaded column to massage the massage area, without the support and connection of a connecting rod, a single massage device could experience uneven force distribution and shift in its rotational axis. The connecting rod in this patent, by connecting the two massage devices, forms a stable structural framework, effectively preventing this shift. Even during high-intensity massages, the massage component's rotational axis remains stable, thereby increasing its strength and durability in high-speed settings.

[0041] In some embodiments, the massage device is a massage pillow, which can be a neck massage pillow, a waist massage pillow, or a back massage pillow. Specifically, the massage device also includes a pillow body, on which a massage mechanism is disposed. When a user's desired massage area (e.g., the neck, waist, back, etc.) is pressed against the pillow body, a massage head of the massage mechanism is configured to massage the desired massage area against the user's desired massage area. For example, the massage head can provide a massage effect on the desired massage area by rotating and / or adjusting its depth.

[0042] See also Figure 4-Figure 5 In this embodiment, the threaded column 220 includes a mounting portion 223 for fixedly connecting the massage head and a threaded portion 224 that is threadedly engaged with the drive gear. The connecting rod 400 is disposed on the mounting portion 223. In this embodiment, the threaded portion 224 is an external thread located on the outer wall of the threaded column 220. In more detail, the threaded column 220 includes a rod body, on the outer circumference of which an external thread is provided. The external thread can be a triangular thread or a trapezoidal thread, etc. The threaded column 220 is in transmission connection with the drive device 200 and can rotate under the drive of the drive device 200. Specifically, the drive gear 210 is a cylindrical sleeve, and an internal thread is provided on the inner side wall of the sleeve. The internal thread is adapted to the external thread of the threaded portion 224. Accordingly, the internal thread can be a triangular thread or a trapezoidal thread, etc. The drive gear 210 is nested outside the threaded post 220, with the internal threads meshing with the external threads. It can be understood that when the threaded post 220 rotates relative to the drive gear 210, the threaded post 220 moves along its axial direction. The massage head 310 is fixedly connected to the threaded post 220 and moves with it. Furthermore, to further strengthen the threaded fit between the threaded post 220 and the threaded sleeve, the mating portion of the threaded portion 224 and the threaded sleeve accounts for 1 / 3 to 2 / 3 of the thread length.

[0043] See also Figure 6-Figure 7The limiting structure includes an upper limiting portion 221 and a lower limiting portion 222. The limiting structure is disposed on the threaded post 220. When the threaded sleeve and the limiting structure are separated, the threaded post 220 moves axially along the drive gear 210 to move the limiting structure closer to and farther from the drive gear 210. The limiting structure cooperates with the drive gear 210 to restrict the drive gear 210 from further axial movement along the threaded post 220 when the drive gear 210 cooperates with the limiting structure. The drive device 200 drives the threaded post 220 to rotate. When the massage head 230 contacts the massage area to be massaged, the threaded post 220 can move axially to adjust the massage depth of the massage head 230. When the limiting structure interferes with the drive gear 210, the drive gear 210 drives the threaded post 220 to rotate, and the massage head 230 rotates with the threaded post 220 to massage the massage area to be massaged. Specifically, the lower limiting portion 222 includes a limiting block 2221 disposed at one axial end of the threaded column 220. When the massage head 230 moves to a first position corresponding to the first massage depth, the limiting block 2221 can abut against one end of the drive gear 210 to limit further axial movement of the drive gear 210 along the threaded column 220, thereby enabling the drive gear 210 to drive the massage head 230 to rotate. The upper limiting portion 221 includes a radially raised shoulder 2211 disposed at one end of the threaded column 220 away from the limiting block 2221. When the threaded column 220 and the drive gear 210 move relative to each other to a second position corresponding to the second massage depth, the shoulder 2211 can abut against the other end of the drive gear 210 to axially limit the drive gear 210, thereby enabling the threaded sleeve to drive the massage head to rotate.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
