Description

Technical Field

[0001] This utility model relates to the field of massage technology, specifically to a waist massage device, and more particularly to a rotating and lifting massage waist support mechanism. Background Technology

[0002] With the development and advancement of technology, and the widespread use of electronic products and electronic office work, the number of people in a sub-healthy state is gradually increasing. Prolonged sitting puts significant pressure on the lumbar spine, which can eventually lead to damage and even disease. Incorrect posture, such as crossing one's legs, can cause pelvic tilt, uneven pressure on the lumbar spine, and uneven stress on the intervertebral discs, potentially leading to lumbar disc herniation.

[0003] As more and more people suffer from lumbar spine problems, various lumbar massage pillows have appeared on the market. Currently, most massage devices mainly achieve local massage of the body through the rotation of the massage head or vibration massage.

[0004] CN202322564776.3 discloses a massager that uses a rotating massage head for massage. However, the massage head of this massager cannot be adjusted in height, thus failing to meet massage needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to solve the technical problem that the massage head of the lumbar massage mechanism in the prior art cannot be raised or lowered, this utility model provides a rotating and raising massage lumbar support mechanism, which can control the raising and lowering of the massage head while the massage head is rotating, thereby improving the massage effect and making the massage more comfortable.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a rotating and lifting massage waist support core, comprising: a rotating motor, the output end of which is connected to a rotating gear, the rotating gear being connected to a massage head to drive the massage head to rotate; a lifting motor, the output end of which is connected to a lifting gear, the inner side of which is engaged with a lifting block, the lifting gear driving the lifting block to rotate, thereby causing the lifting block to push the massage head to rise and fall axially; and a massage head, which is circumferentially connected to the rotating gear for power transmission and axially slidably connected to the rotating gear, so that the massage head can rise and fall simultaneously while rotating.

[0007] This utility model relates to a rotary lifting massage waist support mechanism, which uses a rotary motor to control the rotation of the massage head for massage. At the same time, the lifting motor can drive the massage head to rise and fall axially while it is rotating, thus achieving the effect of lifting the massage head for massage.

[0008] Furthermore, in order to enable the lifting block to move up and down, the inner ring of the lifting gear and the outer wall of the lifting block have toothed structures, so that the lifting gear meshes with the lifting block.

[0009] Furthermore, in order to prevent the lifting block from disengaging from the lifting gear, the inner ring of the lifting gear and the outer edge of the bottom of the lifting block partially overlap in the axial direction.

[0010] Furthermore, in order for the lifting block to push the massage head up and down, the upper end of the lifting block has a support ring extending upward along the axial direction, the support ring abutting against the massage head, and the support ring being rotatable relative to the massage head.

[0011] Furthermore, in order to connect the lifting block and the massage head, the lower inner side of the lifting block has a stepped structure, and the bottom of the massage head has a T-shaped head, with the stepped structure abutting against the T-shaped head.

[0012] Furthermore, in order to support the lifting gear, a support base is fixedly connected to the lower part of the lifting gear, the bottom of the support base is disposed inside the rotating gear, and the bottom of the support base has an annular protrusion that contacts the first support base.

[0013] Furthermore, in order for the massage head to be rotatable and have a degree of freedom of axial movement, the rotating gear has a drive shaft, the massage head is fixedly connected to the drive shaft in the circumferential direction, and the massage head is slidably connected to the drive shaft in the axial direction.

[0014] Furthermore, in order to provide a support base, the rotating gear also has a groove, and the bottom of the support base is located in the groove.

[0015] Furthermore, in order to symmetrically arrange the massage heads for massage, the massage heads are arranged symmetrically from left to right, the output end of the rotary motor is connected to the rotary gear through the first transmission gear, and the output end of the lifting motor is connected to the lifting gear through the second transmission gear.

[0016] Furthermore, in order to save space, both the rotary motor and the lifting motor are dual-axis output motors, and the rotary motor and the lifting motor are arranged in parallel.

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

[0018] 1. The rotating and lifting massage waist support mechanism of this utility model uses a rotating motor and a rotating gear to drive the massage head to rotate and massage. During the rotation massage, the massage head is lifted and lowered axially through the lifting motor, lifting gear and lifting block, thereby achieving the lifting massage effect and making the massage more comfortable.

[0019] 2. The rotating and lifting massage waist support mechanism of this utility model has independent and non-interfering rotation and lifting of the massage head, which can achieve a variety of massage effects. At the same time, the whole machine has a compact structure and occupies little space. Attached Figure Description

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Example 1, such as Figures 1 to 3As shown, a rotating and lifting massage lumbar support mechanism includes: a rotating motor 1 and a lifting motor 2.

[0029] Specifically, the output end of the rotary motor 1 is connected to the rotary gear 4 via the first transmission gear 3. The rotary gear 4 is connected to the massage head 5 to drive the massage head 5 to rotate.

[0030] Specifically, the massage head 5 is connected to the rotating gear 4 for power transmission in the circumferential direction and is slidably connected to the rotating gear 4 in the axial direction.

[0031] Preferably, the rotating gear 4 has a drive shaft. The massage head 5 is fixedly connected to the drive shaft in the circumferential direction, and the massage head 5 is slidably connected to the drive shaft in the axial direction. The massage head 5 and the drive shaft can be connected by a spline, which allows the drive shaft to drive the massage head 5 to rotate, while the massage head 5 can slide relative to the drive shaft in the axial direction, ensuring the lifting function.

[0032] Specifically, the output end of the lifting motor 2 is connected to the lifting gear 7 via the second transmission gear 6. The inner side of the lifting gear 7 meshes with a lifting block 10. The lifting gear 7 drives the lifting block 10 to rotate, thereby causing the lifting block 10 to push the massage head 5 to rise and fall axially. The lifting motor 2 drives the lifting gear 7 to rotate via the second transmission gear 6. The rotation of the lifting gear 7 causes the lifting block 10 to rise, and the lifting block 10 pushes the massage head 5 to rise synchronously, thus realizing the lifting and falling movement of the massage head 5.

[0033] In actual operation, the massage head 5 rotates and massages according to the above process. While rotating and massaging, the massage head 5 can also lift and massage. The rotation and lifting massages are independent of each other. They can be performed simultaneously or independently, providing more massage methods and improving massage comfort.

[0034] In Example 2, based on Example 1, the inner ring of the lifting gear 7 and the outer wall of the lifting block 10 have toothed structures, so that the lifting gear 7 meshes with the lifting block 10. The gear meshing structure can ensure that the lifting block 10 can be lifted and lowered smoothly. Moreover, the structure is simple and the cost is low.

[0035] Preferably, the inner ring of the lifting gear 7 and the outer edge of the bottom of the lifting block 10 partially overlap in the axial direction. This can prevent the lifting gear 7 from rotating too many times, which would cause the lifting block 10 to detach from the lifting gear 7 and effectively prevent the lifting structure from failing.

[0036] Preferably, the upper end of the lifting block 10 has a support ring 8 extending upward along the axial direction. The support ring 8 abuts against the massage head 5, and the support ring 8 can rotate relative to the massage head 5. The lower inner side of the lifting block 10 has a stepped structure, and the bottom of the massage head 5 has a T-shaped head, with the stepped structure abutting against the T-shaped head. The lifting block 10, the support ring 8, and the massage head 5 are interlocked to form an integral structure, allowing the lifting block 10 to push the massage head 5 through the support ring 8, thereby achieving synchronous lifting and lowering of the massage head 5.

[0037] Preferably, since the support ring 8 and the massage head 5 do not rotate synchronously, a bearing can be installed between them to avoid wear caused by mutual friction.

[0038] In Example 3, based on Example 2, a support base 9 is fixedly connected to the lower part of the lifting gear 7. The bottom of the support base 9 is disposed inside the rotating gear 4, and the bottom of the support base 9 has an annular protrusion that contacts the support base 9. The rotating gear 4 also has a groove, and the bottom of the support base 9 is disposed in the groove. The support base 9 is supported by the groove of the rotating gear 4, thereby ensuring the axial position of the rotating gear 4.

[0039] In Example 4, based on Example 3, the massage heads 5 are arranged symmetrically from left to right. Both the rotary motor 1 and the lifting motor 2 are dual-axis output motors, and they are arranged in parallel. Arranging the rotary motor 1 and the lifting motor 2 in parallel optimizes the installation space, reduces the overall space occupied, and makes the massage head 5 smaller.

[0040] In summary, the rotating and lifting massage waist support mechanism of this utility model can control the lifting and lowering of the massage head while it rotates, thereby improving the massage effect and making the massage more comfortable.

[0041] 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.
