Description

Technical Field

[0001] The invention relates to the technical field of physical therapy and massage, in particular to a reciprocating massage device. Background Art

[0002] As a common health care device, human body massagers are widely used in the fields of home and personal care. With the improvement of people's health awareness and the pursuit of quality of life, there are many types of massagers on the market with different functions. Among them, massagers that use mechanical vibration as the main working mode account for a large market share. This type of massager generates periodic force on specific parts of the human body to achieve the effects of promoting blood circulation, relieving muscle tension and fatigue, etc.

[0003] Traditional human massagers usually use an electric motor to drive an eccentric wheel or other similar mechanisms to achieve the vibration effect, thereby causing the skin and muscles of the massaged area to vibrate. The core of this massage method is to adjust the vibration amplitude and frequency parameters to change the user's massage experience. Specifically, a smaller amplitude combined with a lower frequency can often only provide slight stimulation, and the effect on deep muscle relaxation is limited; when the amplitude is increased and the frequency is increased, the massage feeling can be significantly enhanced, making the massage stimulation more in-depth. However, in actual applications, it is found that although excessive vibration intensity can bring a strong massage feeling in a short period of time, it is also easy to cause discomfort or even numbness in the massaged area, thereby affecting the overall comfort and safety of the massage.

Detailed implementation manners

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are only used to describe the difference in names, and cannot be understood as indicating or implying relative importance. The physical quantities in the formula, if not separately marked, should be understood as basic quantities of the basic units of the International System of Units, or derived quantities derived from the basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1 As shown, the reciprocating massage device provided by the embodiment of the present invention includes: a housing 100, a driving member 200, an elastic frame 300 and a massage head 400; the driving member 200 and the elastic frame 300 are respectively installed on the housing 100, the driving member 200 is transmission-connected with the elastic frame 300, and makes the movable part 301 of the elastic frame 300 reciprocate; the massage head 400 is transmission-connected with the movable part 301.

[0040] When a human body part is subjected to mechanical vibration massage, the skin and muscles are driven to form tremors. If the vibration range is concentrated, it is easy to cause excessive local vibration sensation, resulting in numbness. In addition, when the mechanical vibration lacks restraint, as the vibration intensity increases, the vibration direction and amplitude are prone to disorderly changes, which will lead to too chaotic tremor amplitude and direction of the skin and muscles at the massaged part, thus affecting the massage comfort. In this embodiment, the movable part 301 has degrees of freedom to drive the massage head 400 to reciprocate, thereby forming mechanical vibration massage. The movement range of the massage head 400 increases, and the range of the massage vibration sensation is wider, avoiding numbness caused by overly concentrated vibration sensation range. In addition, the elastic frame 300 can restrain the movable part 301, thereby reducing the disorderly changes in the vibration direction and amplitude of the movable part 301, which can limit the excessive vibration of the massage head 400 and relieve the numb discomfort at the massaged part.

[0041] It is worth adding that the movable part 301 reciprocates under the driving action of the driving part 200. When approaching the limit position of the movement stroke, the elastic force of the elastic frame 300 increases, so that the movable part 301 can move in the reverse direction more smoothly, reducing the vibration of the housing 100 caused by the reciprocating movement of the movable part 301 and reducing the vibration sensation when holding the housing 100.

[0042] As Figure 1 、 Figure 2 and Figure 5 shown, in the embodiment of the present invention, the movable part 301 has degrees of freedom to reciprocate along the x direction; the elastic frame 300 and the massage head 400 are arranged along the z direction, where the x direction is perpendicular to the z direction.

[0043] During massage, the massage head 400 abuts against the skin of the massaged part along the z direction, and the movable part 301 drives the massage head 400 to perform linear reciprocating motion along the x direction, avoiding the hammering action of the massage head 400 on the human body along the z direction during massage. The massage head 400 contacts and drives the massaged part to linearly reciprocate along the skin surface, thereby driving the skin and muscles to tremble, achieving the effects of relaxing muscles and promoting blood circulation, etc., avoiding massage discomfort caused by disorderly changes in the vibration direction, and increasing the range of skin and muscle tremors, which can avoid a relatively small concentrated vibration sensation range, so that numbness at the massaged part can be avoided.

[0044] It should be noted that the movable part 301 can have degrees of freedom to reciprocate along the x direction through the elastic structure of the elastic frame 300 itself, or by providing a slide rail or chute extending along the x direction on the housing 100, and the movable part 301 is matched with the slide rail or chute, so that the movable part 301 can reciprocate along the x direction.

[0045] As Figure 1 、 Figure 2 、Figure 4 , Figure 5 and Figure 6 As shown in ,

[0046] , one end of the movable part 301 is connected to the first elastic support part 302, and the other end is connected to the second elastic support part 303. Among them, the x direction points from the first elastic support part 302 to the second elastic support part 303; the first elastic support part 302 and the second elastic support part 303 are respectively connected to the housing 100.

[0046] In an alternative embodiment, the first elastic support part 302 and the second elastic support part 303 are both configured as springs that can elastically expand and contract in the x direction. The movable part 301 is supported by the first elastic support part 302 and the second elastic support part 303 together, so that the movable part 301 can reciprocate in the x direction.

[0047] In this embodiment, the first elastic support part 302 and the second elastic support part 303 are both configured as metal shrapnel. The movable part 301 is supported between the two metal shrapnels. The two metal shrapnels can extend in the z direction and can reciprocally elastically tilt in the x direction, so that the movable part 301 reciprocates in the x direction. In addition, when the movable part 301 reciprocates in the x direction to the stroke limit position, the extension dimension of the two tilted metal shrapnels in the z direction decreases. It can be understood that: as the movable part 301 moves towards the stroke end, it will also shrink slightly in the z direction. When massaging, as the massage head 400 reciprocates, at the stroke limit position, as the movable part 301 contracts in the z direction, the pressing force of the massage head 400 on the skin weakens, so that the pressure on the skin at the tremor limit position weakens, reducing massage discomfort and improving massage comfort.

[0048] See Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the first elastic support part 302 includes: a first longitudinal arm 321, a first bending part 322 and a first spring arm 323. The first longitudinal arm 321 and the first spring arm 323 are spaced apart and extend along the z direction respectively. The top end of the first longitudinal arm 321 is connected to the movable part 301, and the bottom end of the first longitudinal arm 321 is connected to the bottom end of the first spring arm 323 through the first bending part 322; the second elastic support part 303 includes: a second longitudinal arm 331, a second bending part 332 and a second spring arm 333. The second longitudinal arm 331 and the second spring arm 333 are spaced apart and extend along the z direction respectively. The top end of the second longitudinal arm 331 is connected to the movable part 301, and the bottom end of the second longitudinal arm 331 is connected to the bottom end of the second spring arm 333 through the second bending part 332; the top ends of the first spring arm 323 and the second spring arm 333 are respectively connected to the housing 100.

[0049] Wherein, hook portions are respectively provided at the tops of the first spring arm 323 and the second spring arm 333, and the first spring arm 323 and the second spring arm 333 are respectively connected to the housing 100 through the hook portions. An activity gap is formed between the first longitudinal arm 321 and the first spring arm 323 at an interval, and an activity gap is formed between the second longitudinal arm 331 and the second spring arm 333 at an interval. The first spring arm 323 and the second spring arm 333 are elastically deformed and tilted, so as to realize the reciprocating movement of the movable portion 301 along the x direction.

[0050] Furthermore, the first elastic support portion 302 and the second elastic support portion 303 are respectively formed by bending a sheet-like structure; the thickness dimension of the first spring arm 323 is smaller than the thickness dimension of the first longitudinal arm 321, and the thickness dimension of the second spring arm 333 is smaller than the thickness dimension of the second longitudinal arm 331. By reducing the thickness dimensions of the first spring arm 323 and the second spring arm 333, the first spring arm 323 and the second spring arm 333 can be more easily bent and deformed, thereby reducing the elastic resistance required to drive the movement of the movable portion 301, making the driving member 200 drive the movable portion 301 to act more smoothly and with higher transmission efficiency.

[0051] In addition, when the sheet-like structure is elastically deformed, it is mainly the change in the degree of bending, and it is not easy to generate torsional deformation. Furthermore, it can ensure that the degree of freedom of the movable portion 301 is mainly reflected in the reciprocating movement in the x direction, the vibration massage action direction generated by the massage head 400 driven by the movable portion 301 is more orderly, the massage comfort is higher, and it can also avoid the offset of the movable portion 301 during the reciprocating movement, thereby preventing the movable portion 301 from rubbing or bumping against the inner wall of the housing 100 due to skewing, reducing the equipment operation noise, and prolonging the service life of the equipment.

[0052] In this embodiment, the movable portion 301, the first elastic support portion 302 and the second elastic support portion 303 are configured as an integral structure. The movable portion 301, the first elastic support portion 302 and the second elastic support portion 303 can be formed into an integral structure by stamping or bending a metal material, and their structural performance can also be improved through heat treatment, with better elasticity and flexibility, and being easy to process and having lower production costs.

[0053] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the driving member 200 includes: a motor 210 and an eccentric wheel 220; the eccentric wheel 220 is in transmission connection with the motor 210, an eccentric shaft 221 is connected to the eccentric wheel 220, and the axis of the eccentric shaft 221 is spaced and parallel to the axis of the eccentric wheel 220; the eccentric shaft 221 is in transmission connection with the movable portion 301.

[0054] Among them, the axes of the eccentric wheel 220 and the eccentric shaft 221 both extend in the z direction. The motor 210 drives the eccentric wheel 220 to rotate around its own axis, thereby driving the eccentric shaft 221 to rotate around the axis of the eccentric wheel 220. The movable part 301 can be drivingly connected through the eccentric shaft 221, so as to drive the movable part 301 to perform periodic motion in a plane perpendicular to the eccentric shaft 221. The stroke range of the movable part 301 is relatively large, which can make the vibration range of the massage head 400 much larger than the vibration range formed by a conventional vibration motor, and the shaking effect around the massaged part is better, and the massage comfort is higher.

[0055] In an alternative embodiment, the driving member 200 further includes a connecting rod 230. One end of the connecting rod 230 is hinged to the eccentric wheel 220 through the eccentric shaft 221, and the other end of the connecting rod 230 is hinged to the movable part 301.

[0056] When the eccentric wheel 220 drives the eccentric shaft 221 to rotate around the axis of the eccentric wheel 220, the eccentric shaft 221 drives the connecting rod 230. The connecting rod 230 is hinged to the movable part 301 through the shaft portion 305 connected to the movable part 301, so as to push and pull the movable part 301, and further drive the movable part 301 to reciprocate in the x direction.

[0057] In addition, in other alternative embodiments, the driving member 200 can also adopt an electromagnetic driving mechanism, which uses the magnetic force generated by an electromagnet and realizes the reciprocating change of the magnetic force, so as to directly drive the magnet to reciprocate, and the movable part 301 can be driven to reciprocate in the x direction through the magnet.

[0058] Such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in another alternative embodiment, the movable part 301 is connected with a shock absorber 500, and the eccentric wheel 220 is drivingly connected with the shock absorber 500 to drive the movable part 301.

[0059] Among them, the eccentric wheel 220 can be directly in contact with the shock absorber 500 through the eccentric shaft 221 to realize transmission, or the eccentric wheel 220 can be hinged to one end of a rod through the eccentric shaft 221, and the other end of the rod is hinged to the shock absorber 500. The shock absorber 500 is pushed and pulled through the rod, and then the movable part 301 is driven to reciprocate. The shock absorber 500 can reduce the mechanical impact of the transmission from the driving member 200 to the movable part 301, reduce the vibration noise, and improve the quietness during the massage process.

[0060] In an alternative embodiment, a groove 311 can be provided on the movable part 301, and the shock absorber 500 is inserted into the groove 311.

[0061] Among them, the movable part 301 is processed to form a groove 311 by stamping or machining, etc. The shock-absorbing member 500 is embedded in the groove 311, so as to realize the tight connection between the movable part 301 and the shock-absorbing member 500, and the structure is compact. In addition, a shaft part 305 is connected to the movable part 301, and the shock-absorbing member 500 is provided with a hole position that fits the shaft part 305. The shock-absorbing member 500 is installed in the groove 311, and the shaft part 305 is inserted into the hole position on the shock-absorbing member 500, so that the connection between the shock-absorbing member 500 and the movable part 301 is more stable. Moreover, the shock-absorbing member 500 can be in interference fit in the groove 311, or the shock-absorbing member 500 can be bonded to the movable part 301 and the shaft part 305, thereby improving the connection stability.

[0062] As Figure 3 、 Figure 5 and Figure 6 shown, in an alternative embodiment, the shock-absorbing member 500 is provided with a sliding groove 501 extending in the y direction, and the eccentric shaft 221 extends in the z direction, where the x direction, y direction, and z direction are perpendicular to each other in pairs; the eccentric shaft 221 is slidably fitted in the sliding groove 501.

[0063] When the eccentric wheel 220 rotates, the eccentric shaft 221 can slide along the sliding groove 501, and further drive the shock-absorbing member 500 to reciprocate in the x direction, and the shock-absorbing member 500 and the movable part 301 can synchronously reciprocate in the x direction.

[0064] It should be noted that when the elastic frame 300 is in a natural state, or the elastic forces of the first elastic support part 302 and the second elastic support part 303 cancel each other out, so that the movable part 301 is at the stroke center position in the x direction. At this time, the plane where the axis of the eccentric shaft 221 and the axis of the eccentric wheel 220 are located is parallel to the yz plane. As the eccentric wheel 220 is driven to rotate, the eccentric shaft 221 drives the movable part 301 to reciprocate in the x direction. As the movable part 301 moves away from the stroke center position, the elastic resistance received by the movable part 301 gradually increases, and the speed in the x direction gradually decreases. The direction change is smoother during the round-trip process, and the vibration noise is smaller.

[0065] In addition, since the movable part 301 drives the massage head 400, and the massage head 400 contacts the skin and reciprocates in the x direction. As the movable part 301 gradually decelerates and reverses at both ends of the stroke in the x direction, the pulling effect of the massage head 400 on the skin at the extreme position of the stroke in the x direction is weakened, and the tremors of the skin and muscles are more soothing, and the massage comfort is higher.

[0066] As Figure 1 and Figure 2As shown, the driving member 200 can be powered by a rechargeable battery installed in the housing 100 or by a removable dry battery. To avoid the trouble of repeatedly replacing the battery, a rechargeable battery is used and is paired with a power display screen or indicator light, making the massager more convenient to use.

[0067] As Figure 1 , Figure 4 and Figure 6 shown, the movable part 301 is connected to a support part 304. The support part 304 is inserted into the massage head 400. The movable part 301 can drive the support part 304 to reciprocate in the x direction, and drive the massage head 400 to achieve reciprocating vibration massage through the support part 304.

[0068] In an alternative embodiment, the support part 304 can be a rigid support body. The rigid support body can be supported inside the soft massage head 400, thus preventing the massage head 400 from deforming excessively due to softness, and further preventing the massage strength from weakening due to the excessive softness of the massage head 400. Through such a design, both the soft touch of the massage head 400 is retained and its ability to provide a stable and effective massage intensity during operation is ensured.

[0069] In another alternative embodiment, the support part 304 can be a soft rubber support body. The soft rubber support body can drive the massage head 400 to reciprocate, and the soft rubber support body can undergo elastic deformation, thereby achieving flexible transmission. This can not only reduce the transmission impact but also improve the massage comfort, making it suitable for people who are sensitive to massage strength. Moreover, when the massage head 400 is made of a soft material, the soft massage head 400 is sleeved with the soft rubber support body, and the nesting of the two makes the overall structure softer and the skin feel more comfortable.

[0070] In an alternative embodiment, the support part 304 can also be detachably connected to the movable part 301 by means of threaded fit or snap connection, etc., so that the support part 304 with different hardness levels and elastic coefficients can be replaced.

[0071] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 shown, the massage head 400 includes a soft rubber head 420. The soft rubber head 420 is in transmission connection with the movable part 301, and the massage comfort is improved by contacting the skin with the soft rubber head 420.

[0072] Furthermore, the massage head 400 further includes a mounting bracket 410. The soft rubber head 420 is connected to the mounting bracket 410, and the mounting bracket 410 is detachably connected to the housing 100.

[0073] Multiple massage heads 400 with soft rubber heads 420 of different shapes and hardness can be configured, and the user can replace the massage heads 400 according to their preferences during massage.

[0074] It should be noted that the soft rubber head 420 is in interference fit or sealed and bonded with the mounting bracket 410, and then the mounting bracket 410 is tightly connected to the housing 100. The driving member 200 and the elastic bracket 300 can be sealed inside by the housing 100 and the massage head 400 together.

[0075] In addition, the massage head 400 can also be made of a soft material formed integrally, such as silicone, latex or foam material. These different materials may vary in touch and durability, thus providing different user experiences. Multiple independent small massage units can also be installed on the mounting bracket 410, and each unit can be made of different soft materials. Such a design can allow the user to obtain a richer massage experience.
