Abstract

This utility model discloses a miniaturized kneading and clamping massage mechanism, including a housing and a drive unit disposed within the housing. The output shaft of the drive unit is connected to a transmission assembly. The transmission assembly includes eccentric wheels symmetrically arranged on both sides of the output shaft. Each eccentric wheel has a helical gear on its circumference that meshes with the output shaft. The eccentric wheels are connected to a first massage assembly and a second massage assembly. The output shaft drives the helical gear to rotate, thereby causing the eccentric wheels to reciprocate and drive the first and second massage assemblies to move synchronously. This miniaturized kneading and clamping massage mechanism reduces the transmission structure between the motor and the eccentric wheels, and narrows the distance between the eccentric wheels, thus reducing the overall size of the device, occupying less space, and providing ample design space for the massage heads.

Description

Technical Field

[0001] This utility model relates to the field of massage device technology, specifically to a massage mechanism, and more particularly to a miniaturized kneading and clamping massage mechanism. Background Technology

[0002] As people's work intensity increases, many white-collar workers in cities need to work at their desks for long periods of time, leading to neck and shoulder pain, which can even cause frozen shoulder in severe cases. Therefore, in order to massage the neck and shoulders after work, people have designed various neck and shoulder massagers. These types of massagers can relieve users' fatigue and reduce their soreness to a certain extent.

[0003] CN202410218401.8 discloses a neck massager in which a motor drives an eccentric wheel to rotate through a gear set, thereby driving the first and second massage heads to move and massage the user's neck.

[0004] In existing neck massagers, a multi-stage gear transmission is required between the motor and the eccentric wheel to ensure its proper operation. Since gears occupy internal space, this results in a large gap between the eccentric wheels, leading to a large overall size, complex structure, and high production costs. Furthermore, it restricts the placement of the massage heads due to space constraints. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to solve the technical problem of complex structure and large size of massage core in the prior art, this utility model provides a miniaturized kneading and clamping massage core, which reduces the transmission structure between the drive part and the eccentric wheel, and reduces the distance between the eccentric wheels, thereby reducing the overall size of the machine, occupying less space, and providing sufficient design space for the massage head.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a miniaturized kneading and clamping massage mechanism, including a housing and a drive unit disposed in the housing. The output shaft of the drive unit is connected to a transmission assembly. The transmission assembly includes eccentric wheels symmetrically disposed on both sides of the output shaft. The eccentric wheels have helical gears in their circumferential direction that mesh with the output shaft. The eccentric wheels are connected to a first massage assembly and a second massage assembly. The output shaft drives the helical gears to rotate, thereby causing the eccentric wheels to reciprocate to drive the first massage assembly and the second massage assembly to move synchronously.

[0007] This utility model features a miniaturized kneading and clamping massage mechanism. By reducing the number of gears, the distance between the eccentric wheels can be reduced, making the internal structure of the mechanism more compact and reducing the space required for the mechanism.

[0008] Furthermore, in order to enable the first massage component and the second massage component to move synchronously, the lower end of the eccentric wheel has an eccentric column, which is slidably disposed in the groove of the slider. The first massage component is connected to the eccentric wheel, and the second massage component is rotatably connected to the slider. The reciprocating rotation of the eccentric wheel causes the first massage component to swing left and right, and synchronously drives the slider to slide back and forth to drive the second massage component to swing back and forth.

[0009] Furthermore, in order to enable the first massage component to perform left-right rocking massage, the first massage component includes a massage bracket, the swash plate of the massage bracket is connected to an eccentric wheel and cooperates with the inclined surface of the eccentric wheel, and a fixing block is connected to the eccentric wheel.

[0010] Furthermore, in order to prevent the first massage component from swaying back and forth, the housing is provided with a top cover, the top cover has a groove, the massage bracket extends out of the groove and swings back and forth in the groove, the inner side of the top cover is provided with a guide groove, the massage bracket is provided with a guide post, and the guide post is movably fitted in the guide groove.

[0011] Furthermore, in order to achieve head massage, a neck massage head is connected to the upper end of the massage bracket.

[0012] Furthermore, in order to assemble the drive unit and the eccentric wheel, the drive unit and the eccentric wheel are mounted on a mounting block, which is connected to the housing.

[0013] Furthermore, in order to achieve shoulder massage, the second massage component includes a swing arm rotatably connected to a slider, and a shoulder massage head is connected to the swing arm.

[0014] Furthermore, in order to ensure the position of the shoulder massage head is limited to its forward and backward movement, the bottom of the housing is provided with a limiting groove, and the two sides of the slider slide within the limiting groove.

[0015] Furthermore, to ensure stable transmission, the teeth of the helical gear are inclined downwards in the vertical direction.

[0016] Furthermore, to reduce assembly difficulty, the helical gear and the eccentric wheel are integrally formed.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model of a miniaturized kneading and clamping massage mechanism integrates a helical gear and an eccentric wheel into a single structure. The eccentric wheel is directly driven by the drive unit, eliminating the need for a complex multi-stage gear transmission structure. This reduces the distance between the eccentric wheels, making the internal structure of the mechanism more compact, reducing the space occupied, and lowering costs. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0035] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Example 1, as Figure 1 and Figure 2 As shown, a miniaturized kneading and clamping massage mechanism includes a housing 1 and a drive unit 2 disposed within the housing 1. Specifically, the drive unit 2 is a motor. The output shaft of the drive unit 2 is connected to a transmission assembly.

[0038] Specifically, the transmission assembly includes eccentric wheels 3 symmetrically arranged on both sides of the output shaft. The drive unit 2 and the eccentric wheels 3 are mounted on a mounting block 8, which is connected to the housing 1. The eccentric wheels 3 have helical gears 31 on their circumference that mesh with the output shaft. Because the eccentric wheels 3 have helical gears 31, the motor's output shaft can directly drive the eccentric wheels 3 to rotate, eliminating the need for a complex gear transmission structure and shortening the distance between the two eccentric wheels 3. In this embodiment, the distance between the eccentric wheels 3 is 33mm, while in the prior art CN202410218401.8, the distance is 95.8mm. Without affecting transmission efficiency, this significantly reduces the size of the mechanism, providing more installation position options for the massage head.

[0039] Preferably, in order to reduce noise and improve transmission efficiency, the teeth of the helical gear 31 are inclined downward in the vertical direction.

[0040] Specifically, the eccentric wheel 3 is connected to the first massage component 4 and the second massage component 5. The output shaft drives the helical gear 31 to rotate, thereby causing the eccentric wheel 3 to reciprocate and drive the first massage component 4 and the second massage component 5 to move synchronously.

[0041] Preferably, the lower end of the eccentric wheel 3 has an eccentric column 32, which is slidably disposed within the groove 61 of the slider 6. The first massage component 4 is connected to the eccentric wheel 3, and the second massage component 5 is rotatably connected to the slider 6. The reciprocating rotation of the eccentric wheel 3 causes the first massage component 4 to swing left and right, and simultaneously drives the slider 6 to slide back and forth, thereby driving the second massage component 5 to swing back and forth. The rotation angle of the eccentric wheel 3 is 180°. When the eccentric wheel 3 rotates, the eccentric column of the eccentric wheel 3 moves within the groove 61, simultaneously pushing the slider 6 to move in the back and forth direction. As the slider 6 moves back and forth, it drives the second massage component 5 to swing back and forth for massage.

[0042] Preferably, the bottom of the housing 1 is provided with a limiting groove 11, and the two sides of the slider 6 slide within the limiting groove 11. The limiting groove 11 can limit and guide the forward and backward displacement of the slider 6 to prevent the massage component from shifting during movement.

[0043] Example 2, based on Example 1, such as Figure 3 and Figure 5 As shown, specifically, the second massage component 5 includes a swing rod 51 rotatably connected to the slider 6, and a shoulder massage head 52 is connected to the swing rod 51. The end of the slider 6 is rotatably connected to the swing rod 51 via a connecting shaft. When the slider 6 moves back and forth, it drives the swing rod 51 to swing back and forth, thereby driving the shoulder massage head 52 to swing back and forth synchronously, thus achieving a massage for the user's shoulders.

[0044] Specifically, the slider 6 has a U-shaped structure, and the groove 61 is set close to the middle of the slider 6. The two ends of the groove 61 extend forward and are connected to the swing rod 51.

[0045] Because the distance between the eccentric wheels 3 is reduced, the distance between the two slide grooves 61 can be reduced synchronously. While ensuring the relative distance between the two shoulder massage heads 52, the size of the slider 6 is reduced, the structure of the slider 6 is simplified, and the production cost is reduced.

[0046] Specifically, the first massage component 4 includes a massage bracket 41, the swash plate of the massage bracket 41 is connected to the eccentric wheel 3 and cooperates with the inclined surface of the eccentric wheel 3, and a fixing block 33 is connected to the eccentric wheel 3. When the eccentric wheel 3 rotates, the inclined surface of the eccentric wheel 3 pushes the swash plate, and as the eccentric wheel 3 reciprocates, the first massage component 4 swings left and right.

[0047] Preferably, the upper end of the massage bracket 41 is connected to a neck massage head 42, which massages the user's neck by swinging along with the massage bracket 41.

[0048] Example 3, based on Example 2, such as Figure 4 As shown, specifically, the housing 1 has an upper cover 7, and the upper cover 7 has a groove. The massage bracket 41 extends out of the groove and swings back and forth within the groove. The inner side of the upper cover 7 has a guide groove 71. The massage bracket 41 has a guide post 43, which is movably fitted within the guide groove 71. During the left and right swinging of the massage bracket 41, the guide post 43 also moves synchronously. Because the guide groove 71 has a limiting and guiding effect on the guide post 43, the massage bracket 41 will not wobble in the front and back direction during the swinging process, thereby ensuring the massage trajectory of the neck massage head 42.

[0049] The working principle of this miniaturized kneading and pinching massage mechanism is as follows: When the motor starts, its drive shaft rotates two eccentric wheels 3 in opposite directions. The first massage component 4 swings left and right under the influence of the eccentric wheels 3, and the shoulder massage head 52 massages the user's neck. The second massage component 5 swings back and forth under the influence of the eccentric wheels 3, and the shoulder massage head 52 massages the user's shoulders. The first massage component 4 and the second massage component 5 work synchronously to achieve the kneading and pinching technique.

[0050] In summary, this utility model of a miniaturized kneading and clamping massage mechanism reduces the transmission structure between the drive unit and the eccentric wheel, and narrows the distance between the eccentric wheels, thereby reducing the overall size of the machine, occupying less space, and providing ample design space for the massage head.

[0051] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
