Description

Technical Field

[0001] The utility model relates to the technical field of massage devices, and particularly relates to a kneading and knocking massage movement Background Art

[0002] With the development of society, the working and living rhythms of people are accelerating continuously. People from all walks of life are busy for a better life and have little time for physical exercise. As a result, the physical health index of people is deteriorating. Among them, the situation of office workers who sit in front of computers for a long time, drivers who sit in the driver's cab for a long time, etc. is particularly serious. Due to the need for long-term desk work or staring at the computer, the muscles of the neck, shoulders and waist are severely strained, the qi and blood are not smooth, and diseases such as cervical spondylosis and lumbar disc herniation are easily caused. Therefore, neck and shoulder massagers for massaging the neck and shoulders have emerged on the market. Although they can give a certain degree of massage effect to the human body, although the above-mentioned massage devices can achieve neck massage, shoulder massage, or simultaneous massage of the neck and shoulders, generally, they massage by straight pushing and rotating.

[0003] The utility model patent with the application number of 201510697646.4 discloses a kneading and knocking massage device, which includes a swing arm and a housing. The swing arm includes a left swing arm and a right swing arm; a first group of power sources and a second group of power sources are arranged in the housing; a first group of power sources and a second group of power sources are arranged on the bottom shell of the movement. Both groups of power sources can be motors, and the motors can be respectively combined into one or more groups of transmission devices; this device can achieve the purpose of comprehensively kneading and knocking the back and even the neck and shoulder parts of the human body, and through eccentric connecting rod transmission, it has high stability and can achieve the massage and health care effect on the legs or soles of the feet; the ball head with a simple structure and a short knocking area adopted by this device not only participates in the generation of knocking but also participates in the implementation of the kneading action, and the massage area is significantly increased, and the user feels that the comfort of kneading and knocking is more prominent; this device covers kneading and pinching massage and rubbing and knocking massage, mainly focusing on rubbing and knocking massage, which is different from the usual up and down knocking method, and the massage technique is novel and the comfort is better.

[0004] However, although this patent has achieved rubbing and knocking massage, some people still need up and down knocking massage or a massage method that combines rubbing and knocking with up and down knocking. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a kneading and knocking massage movement with a simple structure that can simultaneously achieve kneading and pinching, rubbing and knocking, and up and down knocking massage methods in view of the above-mentioned deficiencies of the prior art.

[0006] To achieve the above object, the following technical solution is adopted. A kneading and knocking massage mechanism includes a housing. Inside the housing, there are a dual-head motor, a kneading and clamping transmission assembly, and a rubbing and knocking transmission assembly. The output shafts at both ends of the dual-head motor drive the kneading and clamping transmission assembly and the rubbing and knocking transmission assembly to work. It is characterized in that the kneading and clamping transmission assembly includes an eccentric seat driven by the output shaft at one end of the dual-head motor. A kneading and clamping seat is eccentrically driven on the first surface of the eccentric seat, and kneading and clamping heads are installed on the kneading and clamping seat. The rubbing and knocking transmission assembly includes a transmission shaft driven by the other end of the dual-head motor. Eccentric heads with the same or opposite eccentric directions are provided at both ends of the transmission shaft. A knocking arm is sleeved on the eccentric head. A knocking head is installed at the first end of the knocking arm. The eccentric head drives the knocking head on the knocking arm to perform synchronous or misaligned rubbing and knocking actions. The second end of the knocking arm is linked with a knocking transmission assembly on the second surface of the eccentric seat. The knocking transmission assembly includes a swing rod eccentrically sleeved on the second surface of the eccentric seat and a transmission rod rotatably arranged at the second end of the knocking arm. The swing rod and the transmission rod are linked through a spherical center structure. The eccentric seat simultaneously drives the kneading and clamping heads on the kneading and clamping seat to knead and clamp and drives the knocking heads on the knocking arm to knock up and down through the knocking transmission assembly.

[0007] Adopting the above technical solution, the driving shafts at both ends of the dual-head motor are worm gears. One end of the driving shaft drives the kneading and clamping transmission assembly to drive the eccentric seat through a reduction gear set. One end of the driving shaft drives the rubbing and knocking transmission assembly through a transmission helical gear. The helical gear rotates synchronously with the pulley and drives the driven pulley on the transmission shaft through a belt to drive the transmission shaft to rotate. Eccentric heads are eccentrically arranged at both ends of the transmission shaft, so that the knocking arms sleeved on the eccentric heads perform eccentric rubbing and knocking massage. When the eccentric directions of the eccentric heads are the same, that is, the knocking arms on both sides perform synchronous up and down rubbing and knocking. When the eccentric directions of the eccentric heads are opposite, that is, the positions of the eccentric heads on the transmission shaft are one high and one low. At this time, when one knocking arm rises, the other knocking arm falls, thus forming a cyclic misaligned rubbing and knocking massage, and the massage effect is better. When only eccentric rubbing and knocking is performed through the eccentric head, the rising and falling amplitude of the knocking arm is not large, only playing the massage effect of rubbing and knocking. When driving through the knocking transmission assembly, it can increase the knocking amplitude of the knocking arm, so that it can not only knock up and down but also rub and knock, and the massage method is more variable, so that the human body receives a more comfortable massage.

[0008] A kneading and knocking massage mechanism can be further set as: a rotating groove is provided at the second end of the knocking arm, and a rotating head rotatably arranged in the rotating groove is provided at one end of the transmission rod. The rotating head and the rotating groove are rotationally matched through a pin shaft.

[0009] By adopting the above technical solution, the rotating head and the rotating groove can be connected by rotation. When the swing arm is driven by the eccentric seat to swing eccentrically, the swing arm can also be connected with the rotating head to increase the striking height of the striking arm, thereby realizing the massage technique of up and down knocking. The pin shaft can prevent the rotating head from escaping from the rotating groove during rotation, thereby increasing the reliability of use.

[0010] A kneading and percussion massage movement can be further configured as follows: the ball center structure includes a first ball head arranged at the end of the transmission rod away from the rotating head, and a mounting seat is detachably provided at the end of the transmission rod away from the eccentric seat, and a first spherical groove is provided in the mounting seat to rotatably cooperate with the first ball head.

[0011] By adopting the above technical scheme, the swinging motion of the rocker arm is converted into the up and down knocking motion of the knocking arm through the cooperation of the first ball head and the first spherical groove, and at the same time, it will not interfere with the rubbing motion of the knocking arm. The first ball head rotates more smoothly and has a larger range of rotation in the first spherical groove. At the same time, it is not easy to cause transmission obstruction of the transmission rod due to the high rotation speed of the rocker arm. Through the ball center structure, the up and down rubbing massage action is increased to the up and down knocking massage action, so that it can adapt to the different needs of different people and has high versatility.

[0012] A kneading and knocking massage movement can be further configured as follows: a knocking groove for the knocking arm to knock up and down and limit the up and down moving distance of the knocking arm is opened on the shell.

[0013] By adopting the above technical solution, the knocking groove can provide the knocking arm with eccentric rubbing and knocking massage as well as up and down knocking massage. The knocking groove is used to limit the up and down moving distance of the knocking arm. The knocking arm is not limited by the shell, but is rubbed and knocked up and down by being sleeved on the two ends of the transmission shaft and the transmission head of the transmission rod. The knocking groove can provide the knocking arm with multiple massage actions at the same time without hindering the knocking arm.

[0014] A kneading and percussion massage movement can be further configured as follows: the mounting seat includes a base fixedly connected to a transmission rod and a cover plate detachably arranged on the base, the cover plate is provided with a limiting protrusion on a side facing the transmission rod, the transmission rod is provided with a limiting groove for the limiting protrusion to extend into and abut against, and a first spherical groove is formed on the inner wall when the base and the cover plate are assembled.

[0015] The above technical solution is adopted to fix the base on the transmission rod so that when installing the first ball head of the transmission rod, the first ball head can be embedded in the base first to achieve the effect of positioning and installation, and then the limiting protrusion of the cover plate is inserted into the limiting groove at an angle, and finally the cover is covered on the base and fixedly connected by bolts. The inner walls of the bottom plate and the cover plate are both hemispherical grooves, and the combination of the two forms a first spherical groove, which is more convenient for installation or disassembly and can be used to position the first ball head during installation.

[0016] A kneading and knocking massage movement can be further configured as follows: the kneading and clamping seat includes a mounting portion, a kneading and clamping arm for mounting a kneading and clamping head, and a spherical rotating portion located between the mounting portion and the kneading and clamping arm; the spherical rotating portion is rotatably arranged on a shell or a component fixed to the shell; a rotating cavity is provided on the shell or a component fixed to the shell; the inner wall of the rotating cavity abuts and limits the outer peripheral surface of the spherical rotating portion; limit guide blocks are symmetrically provided on both sides of the spherical rotating portion; guide grooves that cooperate with the limit guide blocks are symmetrically provided on the rotating cavity; a second ball head is eccentrically provided on the first side surface of the eccentric seat; a second spherical groove for the second ball head to extend into and rotate is provided in the mounting portion; the second ball head cooperates with the first spherical groove to make the limit guide block swing up and down in the guide groove and constitute the oscillating motion of the kneading and clamping arm.

[0017] By adopting the above technical scheme, the transmission component is driven to rotate through the more common reduction gear set on the market and the worm gear, the outer peripheral surface of the eccentric seat is rotated through gear meshing, and the eccentric seat eccentrically drives the neck massage component and the shoulder massage component to work at the same time, and the kneading and clamping seat is driven by the eccentric seat to swing through the mounting part, and the kneading and clamping arm extends out of the shell and performs eccentric clamping and massage on the human neck with the movement of the kneading and clamping seat, the front shape of the guide groove is adapted to the limit guide block, the depth of the guide groove is greater than the side width of the limit guide block, and because the limit guide block is symmetrically arranged, when one end is lifted, the other end is lowered, and the spherical rotating part also rotates in the rotating cavity to realize the limited rotation of the middle part of the kneading and clamping seat, so that the kneading and clamping seat can rotate up and down while the limit guide blocks at both ends can move up and down alternately in the guide groove to realize the swing.

[0018] A kneading and percussion massage movement can be further configured as follows: the shell includes a panel fixedly connected thereto, a limit seat is arranged inside the panel, and the limit seat abuts against the panel to form the rotating cavity and the guide groove.

[0019] By adopting the above technical scheme, the kneading and clamping arm can be first installed in the limit seat, and the four corners of the limit seat form a clamping connection through the protrusions of the fixing bolts, and then the panel is covered and fixed to the shell, so that the spherical rotating part and the limit guide block of the kneading and clamping arm are limited in the rotating cavity and the guide groove to rotate up and down and drive the kneading and clamping arm to swing. The swing arc surface can also provide the second ball head with resistance when it swings. Since the eccentric seat has a higher rotation speed when it is driven, when the mounting part swings, the swing of the mounting part is smoother by setting the contact surface to an arc surface. At the same time, the edge of the second spherical groove can resist the depression of the second ball head, thereby achieving a limiting effect without restricting its rotation.

[0020] A kneading and percussion massage movement can be further configured as follows: the limit guide blocks are symmetrically arranged on both sides of the spherical rotating part in a horizontal or vertical manner, and the guide grooves are symmetrically arranged on the rotating cavity in a horizontal or vertical manner and cooperate with the limit guide blocks.

[0021] With the above technical solution, the limiting guide blocks can be horizontally arranged at both ends of the spherical rotating part or vertically arranged at both ends of the spherical rotating part. The rotation trajectories of the two arrangement methods are the same, both realizing a large arc swing.

Eccentric heads 412 with opposite eccentric directions are provided at both ends of the transmission shaft 411. A knocking arm 413 is sleeved on the eccentric head 412. A knocking head 414 is installed at the first end of the knocking arm 413.
