Description

A multifunctional massage movement with interchangeable three motors and two motors Technical Field

[0001] The invention belongs to the technical field of massagers, and in particular relates to a multifunctional massage core with three interchangeable double motors. Background Art

[0002] The movement of a massager is a key component of the massager. Usually, the functions of a massager are mainly determined by the movement of the massager.

[0003] Chinese Utility Model Patent 200720008837.6 discloses a massager mechanism with kneading, percussion, and travel functions. These three functions are independent of each other, with the kneading, percussion, and travel mechanisms each performing their own function. If a user only wants two of these functions or requires different massage techniques, the product must be redesigned and re-molded to produce a single product with only two of these functions or different massage techniques. This requires designing two production lines and creating two molds, which is costly.

[0004] Chinese utility model patent 201820447992.6 discloses a walking and tapping massage mechanism that utilizes a single motor for both tapping and walking massage. This mechanism features a compact and rationally designed structure, a small and thin size, and reduced weight of the massage mechanism. However, this massage technique is limited. To achieve a wider range of massage combinations, adding a motor would require redesigning and re-molding. This would require designing two production lines and re-molding two times to produce two products, resulting in high costs. Technical issues

[0005] The technical problem to be solved by the present invention is to provide a multifunctional massage movement with three interchangeable double motors, which has low cost and convenient switching. Technical Solutions

[0006] The present invention is achieved in that:

[0007] The advantages of the present invention are:

[0008] 1. While three motors can be used to achieve kneading, tapping, and walking functions, the kneading, tapping, and walking functions can also be achieved by removing the walking motor. Switching between these functions can be achieved on the same product, eliminating the need for redesign or remolding, thus reducing costs. Without a one-way bearing, dual motors cannot achieve independent walking (back push or acupressure) massage techniques. They can only achieve small, localized, and simultaneous tapping and walking, or tapping, kneading, and walking, massage techniques that cannot be achieved independently. The dual-motor solution primarily caters to customers who prioritize cost reduction and can tolerate minor functional deficiencies.

[0009] 2. The solution of dual motors equipped with one-way bearings can realize separate kneading massage and separate walking (back push or acupressure) massage techniques in a single direction. The electronic control program can be used to control the walking massage in a small area to make up for the lack of fixed-point massage.

[0010] 3. A variety of massage techniques can be freely combined.

[0021] DETAILED DESCRIPTION

[0022] First embodiment (dual motors without one-way bearings):

[0023] As shown in Figures 1 to 4, a multifunctional massage movement with three interchangeable motors includes: a pair of massage head assemblies, a kneading device, a percussion walking device, an upper cover 2 and a base 1;

[0024] A pair of massage head assemblies, a kneading device and a percussion walking device are installed on the base 1, and the upper cover 2 is buckled thereon, and the pair of massage head assemblies extend outside through the upper cover 2;

[0025] Each massage head assembly includes: two massage heads 101, a fork 102, and a rocker arm 103; the two ends of the fork 102 are respectively connected to a massage head 101, and the lower part of the fork 102 is connected to the rocker arm 103;

[0026] The kneading device includes: a kneading motor 201, a kneading worm wheel 202, a kneading worm 203, a first kneading gear 204, a second kneading gear 205, a kneading shaft 206, and two kneading eccentric sleeves 207; the first kneading gear 204 is arranged on the kneading worm 203, the second kneading gear 205 is arranged on the kneading shaft 206, and the first kneading gear 204 and the second kneading gear 205 are meshed with each other; the two kneading eccentric sleeves 207 are respectively sleeved on both ends of the kneading shaft 206, and an output end of the kneading motor 201 drives the kneading worm wheel 202 and the kneading worm 205 to knead the kneading worm. The rod 203 rotates, the kneading worm 203 drives the first kneading gear 204 to rotate, the first kneading gear 204 drives the second kneading gear 205 to rotate, the second kneading gear 205 drives the kneading shaft 206 to rotate, and the kneading shaft 206 rotates to drive the kneading eccentric sleeve 207 to rotate; the inner ring of the rocker arm 103 is sleeved on the outer ring of the kneading eccentric sleeve 207. When the kneading eccentric sleeve 207 rotates, it drives the rocker arm 103 to reciprocate, the rocker arm 103 drives the fork 102 to move, and the fork 102 drives the two massage heads 104 to move, thereby realizing the kneading function;

[0027] The knocking travel device includes: a knocking motor, a first knocking pulley 302, a second knocking pulley 303, a knocking shaft 304, two knocking eccentric bushings 305, two ball-end connecting rods 306, a travel worm gear 401, a travel gear 402, a travel track gear 403, and a travel shaft 404; the travel worm gear, the travel gear, and the travel track gear are all arranged on the travel shaft;

[0028] In this embodiment, the knocking motor is a double-headed motor 301, and a first knocking pulley 302 is provided on the first output end of the knocking motor (double-headed motor) 301, and a second knocking pulley 303 is provided on the knocking shaft 304, and two knocking eccentric shaft sleeves 305 are respectively sleeved on the two ends of the knocking shaft 304, and each knocking eccentric shaft sleeve 305 is connected to the kneading eccentric shaft sleeve 207 through a ball head connecting rod 306; the first output end of the knocking motor 301 drives the first knocking pulley 302 to rotate, and the first knocking pulley 302 drives the second knocking pulley 303 to rotate through a belt (not shown in the figure), and the second knocking pulley 303 drives the knocking shaft 304 to rotate, and when the knocking shaft 304 rotates, it drives the two knocking eccentric shafts The sleeve 305 rotates, and the knocking eccentric sleeve 305 rotates to drive the kneading eccentric sleeve 207 to reciprocate through the ball head connecting rod 306. When the kneading eccentric sleeve 207 reciprocates, it drives the rocker arm 103 to reciprocate, the rocker arm 103 drives the fork 102 to move, and the fork 102 drives the two massage heads 101 to move, thereby realizing the knocking function; the second output end of the knocking motor 301 drives the traveling worm gear 401 to rotate, the traveling worm gear 401 drives the traveling gear 402 to rotate, the traveling gear 402 drives the traveling shaft 404 to rotate, the traveling shaft 404 drives the traveling track gear 403 to rotate, and the traveling track gear 403 drives the rack (not shown) installed in the massager assembly to move to realize the walking function.

[0029] The base 1 is also provided with a accommodating space 5 for a walking motor. The position of the accommodating space 5 is such that after the walking motor is installed, the walking worm gear 401 is located between the knocking motor 301 and the walking motor. The output worm shaft of the walking motor or the other end of the knocking motor can drive the walking worm gear 401 to rotate, thereby realizing the interchangeability of three and two motors and also achieving the purpose of driving walking.

[0030] Second embodiment (dual motors equipped with one-way bearings):

[0031] As shown in Figure 5, the difference from the first embodiment is that a one-way bearing 309 is installed inside the second knocking pulley 303, and the one-way bearing 309 is sleeved on the knocking shaft 304, so that when the knocking motor 301 rotates in the forward direction, its first output end drives the second knocking pulley 303 to rotate, thereby realizing the knocking function, and the second output end drives the walking worm gear 401 to realize the walking function. When rotating in the reverse direction, the first output end idles, and the second output end drives the walking worm gear to rotate, thereby realizing the walking massage (back pushing or acupressure) function only.

[0032] The third embodiment (three-motor solution):

[0033] As shown in FIG. 6 to FIG. 8 , the difference from the first embodiment is that the striking motor is a single-head motor 308 , and a travel motor 405 is installed in the accommodating space 5 .

[0034] The output end of the single-head motor 308 drives the first knocking pulley 302 to rotate. The first knocking pulley 302 drives the second knocking pulley 303 to rotate via a belt (not shown). The second knocking pulley 303 drives the knocking shaft 304 to rotate. When the knocking shaft 304 rotates, it drives the two knocking eccentric sleeves 305 to rotate. The rotation of the knocking eccentric sleeves 305 drives the kneading eccentric sleeves 207 to reciprocate through the ball joint 306. When the kneading eccentric sleeves 207 reciprocate, the rocker arm 103 is driven to reciprocate. The rocker arm 103 drives the fork 102 to move. The fork 102 drives the two massage heads 101 to move, thereby realizing the knocking function.

[0035] The output worm shaft of the travel motor 405 drives the travel worm gear 401 to rotate, the travel worm gear 401 drives the travel gear 402 to rotate, the travel gear 402 drives the travel shaft 404 to rotate, the travel shaft 404 drives the travel track gear 403 to rotate, and the travel track gear 403 drives the rack (not shown) installed in the massager assembly to move to realize the walking function.

[0036] The present invention can achieve kneading, tapping, and walking functions using three motors, or it can achieve kneading, tapping, and walking functions by removing one of the walking motors. Switching between these functions can be achieved within the same product, eliminating the need for redesign and remolding, resulting in low cost. Without one-way bearings, dual motors lack independent walking massage techniques and can only achieve localized, fixed-point massage. Furthermore, tapping and walking are performed simultaneously, or tapping, kneading, and walking are synchronized, preventing independent walking massage techniques. Without one-way bearings, dual motors lack independent walking (back-pushing or acupressure) massage techniques and can only achieve localized, fixed-point massage. Furthermore, tapping and walking are performed simultaneously, or tapping, kneading, and walking are synchronized, preventing independent walking massage techniques. The dual motor solution with one-way bearings can achieve both independent kneading and independent walking (back-pushing or acupressure) massage techniques in a single direction. Walking massage can be controlled by an electronic control program to target a specific area, compensating for the lack of fixed-point massage. This allows for the flexible combination of multiple massage techniques.

[0037] The above embodiments and drawings do not limit the form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
