The massage instrument is used as a health care physiotherapy equipment in daily life of people, has the effects of relaxing tendons and activating collaterals and promoting blood circulation, and can be used for auxiliary treatment and prevention of lumbar vertebra diseases, cervical spondylosis, scapulohumeral periarthritis, muscle strain and other diseases.

The massage device is generally of a rigid structure, the distance between the massage heads of the massage device cannot be adjusted, and of course, in order to adapt to the requirements of different crowds such as high, low, fat, thin, etc., the massage device of a flexible structure capable of adjusting the distance between the massage heads is also available in the related art.

However, in the related art, a plurality of motors capable of moving independently are generally required to implement linkage between the massage heads, which increases the number of materials and the cost of materials, and further complicates the assembly structure inside the massage apparatus.

Referring to fig. 1 to 8, the present utility model discloses a massage apparatus, which may include: the massage head assembly comprises a movable frame 100, a massage head assembly 200, a tensioning mechanism 300, a spacing adjusting mechanism 400 and a first motor 500.

The massage head assembly 200 is used for massaging a human body, and the massage head assembly 200 interacts with the skin surface of the human body in a self-rotating manner, so that the massage purpose is achieved, so that the massage head assembly 200 is generally rotatably disposed on the movable frame 100, and different numbers of massage head assemblies 200 can be disposed on the movable frame 100 according to the user's requirement, for example, 1, 2, 4 or more massage head assemblies 200 are disposed on the movable frame 100. It is understood that when the movable frame 100 is configured with a plurality of massage head assemblies 200, a corresponding transmission structure is required to achieve the linkage of the plurality of massage head assemblies 200 on the movable frame 100, and the related transmission structure will be described in detail later.

To achieve more arrangement of the massage head assembly 200 and adjustment of the interval, a plurality of movable frames 100 may be provided, and a plurality of movable frames 100 may be sequentially arranged, for example, two movable frames 100 may be arranged side by side, or more movable frames 100 may be arranged. In the present utility model, the adjustment of the interval between the massage head assemblies 200 is achieved by the movement of the movable frame 100, which will be described in detail later.

The tensioning mechanism 300 can be arranged between the adjacent movable frames 100, the massage head assemblies 200 on the adjacent movable frames 100 are connected through the transmission of the tensioning mechanism 300, the tensioning mechanism 300 can be used as a power transmission medium between the movable frames 100, and can enable the interval between the movable frames 100 to keep continuous and stable power transmission in the changing process through the tensioning effect of the tensioning mechanism, so that linkage between the massage head assemblies 200 on each movable frame 100 is realized, and the tensioning principle is described in detail below.

The spacing adjustment mechanism 400 may be drivingly connected between adjacent movable frames 100 to drive the movable frames 100 to move to achieve spacing adjustment.

The first motor 500 is used as a power source for the operation of the massage apparatus, and is connected to one of the massage head assemblies 200 in a driving manner, that is, the massage apparatus of the present utility model can realize the linkage of all the massage head assemblies 200 by only using a single motor drive while realizing the adjustment of the distance between the movable frames 100.

The pitch adjustment mode of the device is as follows:

when the first motor 500 is started, the connected massage head assembly 200 can be driven to rotate, and the rest massage head assemblies 200 are driven to rotate in a following way through the tensioning mechanism 300. Specifically, when only one massage head assembly 200 is provided on the movable frame 100, the power of the first motor 500 is firstly transmitted to the connected massage head assemblies 200, and then transmitted to the rest massage head assemblies 200 through the tensioning mechanism 300, so as to realize linkage between the massage head assemblies 200. When the movable frame 100 is provided with a plurality of massage head assemblies 200, the adjacent massage head assemblies 200 are in transmission connection, the power of the first motor 500 is firstly transmitted to the connected massage head assemblies 200, then transmitted to the rest massage head assemblies 200 on the movable frame 100, then transmitted to the massage head assemblies 200 on the adjacent movable frame 100 through the tensioning mechanism 300, and so on, so as to realize the linkage between the massage head assemblies 200. For example, the tensioning mechanism 300 is an elastic belt to connect the massage head assemblies 200 on different movable frames 100 in a driving manner.

The distance adjusting mechanism 400 may drive the movable frames 100 to move to adjust the distance between the adjacent movable frames 100, for example, the distance adjusting mechanism 400 is a telescopic push rod, and the distance between the adjacent movable frames 100 is changed by self-expansion and contraction, as shown in fig. 1, 6 and 8.

In the case of adjusting the space between adjacent movable frames 100, the tensioning mechanism 300 may adjust the posture according to the space between the movable frames 100, as shown in fig. 4 and 5. Such as the tensioning mechanism 300 as an elastic band, will elastically deform itself with the adjustment of the spacing between the movable frames 100 to accommodate the change in spacing between the movable frames 100, thereby always maintaining a driving connection with the massage head assembly 200. It is understood that when the tensioning mechanism 300 is an elastic band, the above-mentioned posture is adjusted to the elastic deformation of the elastic band.

It can be seen that the tensioning mechanism 300 is provided not only as a power transmission medium between the movable frames 100, but also can perform self-adaptive posture adjustment according to the interval adjustment between the movable frames 100 to maintain stable power transmission between the movable frames 100.

Thus, the massage device can realize the linkage of the multi-massage head assembly 200 only by using a single motor to drive while realizing the interval adjustment, thereby reducing the quantity of materials, lowering the cost of materials, and simplifying the internal assembly structure of the massage device by reducing the design of the motor.

Alternatively, when the tensioning mechanism 300 is the elastic band, the elastic band itself is limited in deformation, so that the movable frame 100 cannot be adjusted in a wide range of distance. To this end, the present utility model, as shown in fig. 4 and 5, may provide a tensioning mechanism 300 including: a first conveyor belt 310 and a telescoping mechanism 320.

The first conveyor belt 310 is wound around the massage head assemblies 200, and the massage head assemblies 200 on adjacent movable frames 100 are connected by transmission of the first conveyor belt 310, for example, the first conveyor belt 310 is a belt, a V-belt, or the like.

The first conveyor belt 310 may surround the telescopic mechanism 320. And the telescopic direction of the telescopic mechanism 320 intersects, for example, is perpendicular to, the direction of the interval adjustment of the movable frame 100.

The telescoping mechanism 320 may abut the first conveyor belt 310 to place the first conveyor belt 310 in tension. Abutment here can be understood as: the first conveyor belt 310 and the telescopic mechanism 320 remain in close proximity and are pressed against each other. The tensioning state can be understood here as: since the telescopic mechanism 320 always maintains the pressing force on the first conveyor belt 310, the first conveyor belt 310 always maintains a tight tension so as to have a sufficient tension on itself to always keep close contact with and press against the wound massage head assembly 200.

It will be appreciated that, since the first conveyor belt 310 and the massage head assembly 200 are kept in close contact with each other, there will be a sufficient amount of friction therebetween, so that when the massage head assembly 200 rotates, rolling friction will be performed between the first conveyor belt 310 and the massage head assembly 200, and thus the first conveyor belt 310 can stably transmit power to the massage head assembly 200 on the adjacent movable frame 100, whereas if the first conveyor belt 310 is not in a tensioned state, the first conveyor belt 310 will be loose and unable to be in close contact with the massage head assembly 200, the first conveyor belt 310 will not have a sufficient friction with the massage head assembly 200, and when the massage head assembly 200 rotates, sliding friction will be performed between the first conveyor belt 310, i.e., a phenomenon of "slipping" will occur, and thus no effective power transmission will be achieved, and no effective linkage will occur between the massage head assemblies 200.

The posture adjustment of the tensioning mechanism 300 is specifically: the telescopic distance of the telescopic mechanism 320 can be adjusted along with the adjustment of the distance between the movable frames 100, so as to realize the posture adjustment of the tensioning mechanism 300 along with the adjustment of the distance between the movable frames 100.

Specifically, when the interval between adjacent movable frames 100 is reduced, the telescopic mechanism 320 is extended to support the first conveyor belt 310 to maintain a sufficient tension, thereby maintaining the tensioned state of the first conveyor belt 310 and preventing the first conveyor belt 310 from being loosened, as shown in fig. 4; and when the interval between the adjacent movable frames 100 increases, the telescopic mechanism 320 is reduced to keep close contact with the first conveyor belt 310, and prevent the first conveyor belt 310 from being excessively tightened to break, as shown in fig. 5.

It can be seen that the amount of adjustment of the spacing between the movable frames 100 will translate into the amount of telescoping of the telescoping mechanism 320. In this way, compared with the simple design of setting the tensioning mechanism 300 as the elastic band, the telescopic mechanism 320 and the first conveyor belt 310 are mutually matched due to the larger telescopic amount of the telescopic mechanism 320, so that the movable frame 100 can have a larger adjustment range, thereby expanding the application range of the massager of the utility model and being suitable for wider crowds.

Alternatively, the telescopic mechanism 320 may be any mechanism that can perform telescopic operation, such as a piston mechanism, an electric push rod, etc., and in order to reduce material cost and improve operability, the telescopic mechanism 320 may be provided as shown in fig. 4 and 5, and includes: the movable block 321, the fixed seat 322 and the elastic piece 323.

The movable block 321 may be slidably engaged with the first conveyor belt 310, that is, the first conveyor belt 310 may maintain sliding contact with each other and generate relative motion during the transmission process, so that the first conveyor belt 310 slides over the movable block 321. The fixed base 322 is used as a mounting base of the telescopic mechanism 320, and can be arranged at intervals with the movable block 321 in the telescopic direction. The elastic piece 323 can be elastically connected between the movable block 321 and the fixed seat 322; the elastic piece 323 is used for driving the movable block 321 to abut against the first conveyor belt 310.

The posture adjustment of the tensioning mechanism 300 is specifically: the distance between the fixed seat 322 and the movable block 321 can be adjusted along with the adjustment of the distance between the movable frames 100; the elastic member 323 can elastically deform along with the adjustment of the distance between the fixed base 322 and the movable block 321.

It can be seen that the elastic deformation of the elastic member 323 has a self-adapting characteristic, specifically, along with the change of the distance between the movable frame 100, the elastic member 323 can follow the response and drive the movable block 321 to move, so as to adaptively adjust the distance between the movable block 321 and the fixed seat 322, and the whole process does not need to be operated and controlled by an operator, compared with the structure that the telescopic mechanism 320 is arranged as an electric push rod, a piston mechanism or the like, the massage apparatus of the utility model is simpler and more convenient for the user to operate.

Alternatively, as shown in fig. 4 and 5, two movable blocks 321 may be provided. The two movable blocks 321 are oppositely arranged towards the telescopic direction, and the fixed seat 322 is arranged between the two movable blocks 321. Thus, more elastic members 323 are needed, and more elastic members 323 can provide a larger driving force to the first conveyor belt 310, so that the first conveyor belt 310 can obtain a larger tension, and the first conveyor belt 310 can have a higher fit degree and a larger extrusion force with the connected massage head assembly 200, so that the first conveyor belt 310 can more effectively exert a transmission function.

Alternatively, as shown in fig. 4 and 5, the number of the elastic members 323 may be an even number so as to correspond to the movable block 321, such as providing two elastic members 323. For example, four elastic members 323 are provided, and two movable blocks 321 are connected to the fixed base 322 through one elastic member 323, and another movable block 321 is connected to the fixed base 322 through another elastic member 323, so that the telescopic mechanism 320 gives a larger driving force to the first conveyor belt 310, so that the first conveyor belt 310 obtains a larger tension to maintain a tensioned state.

Alternatively, as shown in fig. 4 and 5, the telescopic mechanism 320 may further include a first guide shaft 324, where the first guide shaft 324 is connected to the fixed seat 322, the axial direction of the first guide shaft 324 is consistent with the telescopic direction, and the elastic member 323 is sleeved on the first guide shaft 324, for example, the elastic member 323 is an elastic sleeve, a spring, or the like. The movable block 321 is provided with a via hole, the via hole is sleeved on the first guide shaft 324, and the movable block 321 is in guide fit with the first guide shaft 324 towards the telescopic direction.

In this way, during the telescoping process of the telescoping mechanism 320, the movement of the movable block 321 and the deformation of the elastic member 323 will not deviate from the telescoping direction due to the guiding action of the first guiding shaft 324, so as to improve the operability of the massager of the present utility model.

Alternatively, as shown in fig. 4 and 5, the tensioning mechanism 300 may further include a tensioning wheel 330, where the tensioning wheel 330 is disposed between the movable frame 100 and the massaging head assembly 200 and the movable block 321. The tensioning wheel 330 is in sliding engagement with the first conveyor belt 310, i.e. the first conveyor belt 310 can maintain sliding contact and relative movement between the two during the drive process, so that the first conveyor belt 310 slides over the tensioning wheel 330. And the tensioning wheel 330 can be abutted against the first conveyor belt 310, so that a pressing force is generated on the first conveyor belt 310, so that the first conveyor belt 310 generates a larger tension, and the tensioning state can be maintained more effectively, so that the transmission function is realized.

Alternatively, the tensioning wheel 330 may be provided in plural, such as four, to tension the first conveyor belt 310 from plural positions, so that the first conveyor belt 310 is stressed uniformly, and the tensioning is more effective.

Alternatively, the tensioning wheel 330 may be disposed outside the first conveyor belt 310, and the telescopic mechanism 320, the massage head assembly 200, etc. are surrounded on the inside of the first conveyor belt 310, such that the telescopic mechanism 320 generates a tensioning force from the inside to the outside, and the tensioning wheel 330 generates a tensioning force from the outside to the inside to act on the first conveyor belt 310 together, thereby enabling the first conveyor belt 310 to obtain a greater tension to maintain the tensioned state.

Optionally, the tensioning mechanism 300 may further include a second rotating shaft 331, the second rotating shaft 331 is disposed on the movable frame 100, and the tensioning wheel 330 is sleeved on the second rotating shaft 331 and can rotate around an axial direction of the second rotating shaft 331, so that the first conveying belt 310 can more smoothly realize relative movement with the tensioning wheel 330 in a transmission process, and avoid occurrence of abnormal situations such as jamming.

Optionally, the tensioning wheel 330 is provided with a second chute, the movable block 321 is provided with a first chute, and the first chute and the second chute are both clamped to the first conveyor belt 310, so that the tensioning wheel 330 and the movable block 321 are separated in the transmission process of the first conveyor belt 310, and the transmission reliability is further ensured.

Alternatively, as described above, the spacing adjustment mechanism 400 may be any mechanism that can implement spacing adjustment, such as an electric push rod, a piston mechanism, or the like, for example, where the electric push rod is disposed between two adjacent movable frames 100, and the electric push rod can push the movable frames 100 to move during the extension and retraction process, so as to implement spacing adjustment. The present utility model provides a pitch adjustment mechanism 400 comprising: a second motor 410, an adjusting screw 420 and a screw sleeve 430.

The second motor 410 is a power source of the space adjusting mechanism 400, and the second motor 410 is connected to the adjusting screw 420 in a driving manner, for example, a worm gear mechanism, a gear mechanism, etc. are disposed between the second motor 410 and the adjusting screw 420 to drive the adjusting screw 420 to rotate, and an axial direction of the adjusting screw 420 is consistent with a space adjusting direction of the movable frame 100.

The screw sleeve 430 is disposed on the movable frame 100 and is screwed to the adjusting screw 420. The second motor 410 can drive the threaded sleeve 430 to move along with the adjusting screw 420 in the direction of adjusting the distance between the movable frames 100 to adjust the distance between the adjacent movable frames 100, specifically, when the second motor 410 is started, the adjusting screw 420 is driven to rotate, and the rotational movement of the adjusting screw 420 is converted into the linear movement of the threaded sleeve 430 in the axial direction of the adjusting screw 420 through the threaded connection with the threaded sleeve 430, so as to drive the movable frames 100 to move to adjust the distance.

It can be seen that the second motor 410, the adjusting screw 420 and the screw sleeve 430 form a screw transmission mechanism, and the screw transmission mechanism has large torque and stable transmission, and is particularly suitable for adjusting the space between small-sized devices such as a massager and the like.

Alternatively, as described above, only one massage head assembly 200 may be provided on the movable frame 100, and a plurality of massage head assemblies 200 may be provided on the movable frame 100 of the present utility model, and adjacent massage head assemblies 200 on the movable frame 100 are in transmission connection with each other. Thus, when the first motor 500 is started, the plurality of massage head assemblies 200 can be rotated simultaneously, so as to provide a larger massage area for the user and improve the user experience.

Alternatively, for a specific manner of driving connection between the adjacent massage head assemblies 200 on the movable frame 100, gears may be disposed on the massage head assemblies 200, so that the driving connection between the massage head assemblies 200 is achieved by means of gear engagement.
