Description

A silence motor for cervical vertebra massager

Technical Field

The invention relates to a health-care massage device, in particular to a mute motor for a cervical vertebra massager.

Background

With the increase of working pressure and the decrease of movement, people suffering from cerebrovascular diseases have more and more. Through the massage of the neck, the neck artery, the vein and the nerve are effectively stimulated, the fatigue of the head and the neck can be effectively relieved, and the cerebral blood vessel is protected. The cervical vertebra massager is the most commonly used neck massager for people. The cervical vertebra massager drives the massage ball to rotate through the motor, thereby realizing the massage of the neck. The alternating magnetic field in the motor inevitably contains high-frequency noise, so that the motor can generate high-frequency vibration and noise during operation, and discomfort can be caused to a user when the motor is used for neck massage.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a mute motor for a cervical vertebra massager, which can solve the defects of the prior art, improve the mute effect of the motor and improve the use comfort.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows.

The utility model provides a silence motor for cervical vertebra massager, includes the casing, and the casing internal fixation has the stator, and the output shaft is installed through the bearing at casing both ends, installs the rotor on the output shaft, be provided with the cavity in the output shaft, the annular range has three rubber post in the cavity, the both ends of rubber post respectively with the top and the bottom fixed connection of cavity, through the annular spring body coupling between the three rubber post, the rotor inside wall is through first connecting rod and rubber post fixed connection, the junction of first connecting rod and output shaft is provided with the rubber sleeve.

Preferably, four shock absorbers are uniformly arranged between the bearing and the shell; the bumper shock absorber includes two respectively with bearing and casing fixed connection's sheet rubber, mutual overlap joint between two sheet rubbers, through first spring body coupling between bearing and the casing, two sheet rubbers are run through in first spring body coupling, and the outside parcel of bumper shock absorber has rubber bellows.

Preferably, the contact part of the two rubber sheets is provided with a hole, and the hole is filled with foaming sponge.

Preferably, the bearing comprises an inner sleeve and an outer sleeve which are buckled together, a support frame is arranged between the inner sleeve and the outer sleeve, a plurality of mounting holes are uniformly formed in the support frame, and balls are clamped in the mounting holes; the inner sleeve is fixedly connected with the rubber column through a second connecting rod.

Preferably, the edge of the support frame is provided with rollers which are in sliding contact with the inner sleeve and the outer sleeve respectively, the edge of the mounting hole is provided with a Teflon outer sleeve, and the Teflon outer sleeve is in interference fit with the ball bearings.

Preferably, a groove is formed in the contact surface of the Teflon outer sleeve and the ball, and a sponge layer is arranged in the groove.

Preferably, the side surface of the support frame is uniformly provided with a plurality of through grooves, and reinforcing ribs are fixed on diagonal lines of the through grooves.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: according to the invention, the three-level vibration and noise reduction mechanism is designed on the output shaft, the bearing and the shell according to the source of the vibration noise of the motor, so that the vibration and the noise of the motor during operation are reduced to the maximum extent, and the comfort level of a user is improved. Because the output shaft is the part of direct and rotor connection, the high-frequency vibration that appears when the rotor rotates can directly transmit to the output shaft on, through the rubber post of installing three mutual flexible coupling, cushions the absorption to the high-frequency vibration that the rotor produced, reduces the vibration and outwards transmits. The output shaft is connected with the shell through a bearing. In the bearing, the inner sleeve is fixedly connected with the rubber column through the second connecting rod, and vibration can be buffered and absorbed by the rubber column. When the bearing operates, the friction between the balls and the inner sleeve and the outer sleeve is the main reason of noise generation of the bearing, and the balls can be elastically buffered by arranging the Teflon outer sleeve and the balls in interference fit, so that the friction noise is reduced; in addition, because the massage balls periodically apply pressing force, the bearing is stressed unevenly, and the Teflon outer sleeve can effectively protect the balls and reduce the abrasion of the balls. The groove on the Teflon outer sleeve is used for collecting impurities in the lubricating grease, so that the running smoothness of the whole bearing is improved. The through groove can accelerate the circulation efficiency of the lubricating grease in the bearing, and the reinforcing ribs in the through groove can improve the torsional strength of the support frame and keep the stability of the whole bearing when the bearing receives asymmetric force application. The bearing is connected with the machine shell through the shock absorber, and the shock absorber performs secondary buffering on vibration which is not absorbed by buffering. The buffer of the shock absorber is realized by two-stage elastic deformation of the rubber sheet and the first spring body. The residual vibration of the shock absorber can be effectively reduced. The holes with the foaming sponge can effectively absorb noise generated when the rubber sheets rub against each other.
