Abstract

The utility model provides a bidirectional driving massaging mechanism for a massage chair. The front side of a hosuing forms two longitudinal axle apertures which are coaxial and independently spaced, and two driving axles are arranged in the axle apertures by being matched with an upper and a lower groups of positioning bearings. The two driving axles in an independent driving state are respectively sheathed with a helical gear and a worm gear and are meshed with corresponding driven gears of transverse axle rods. The ends of the two driving axles extending outside the housing are respectively provided with belt pulleys, and the two belt pulleys are respectively controlled by an electric motor in individual transmission in a positive and an inverse rotating directions. Both ends of a through spindle of the electric motor are respectively sheathed with a positive and a negative single direction bearings. In this way, the whole driving mechanism can be greatly compacted and can increase transmission efficiency and movement accuracy.

Description

The two-way transmission massage mechanism of massage armchair

This utility model relates to a kind of electrically driven (operated) massage apparatus of using, particularly a kind of massage mechanism.

The modern makes the people feel that smart tired power is tired owing to be busy with one's work, labour worker especially, and more normal generation muscular soreness of whole body, mat massage this moment blood circulation promoting, Shujin bone then are the allaying tiredness best approaches, thereby have various masseurs to come out.

Traditional massage apparatus, it is the single dynamic formula massage of doing, use for a long time with after the same action massage, not only fail to alleviate muscle, easily cause discomfort on the contrary, have a strong impact on massage effect, thereby have the massage armchair massage mechanism of multi-functional transmission to come out, can select best use pattern for user massage functions such as to beat, rub.

But with regard to the actuating device of traditional massage mechanism, mainly be different transmission configurations with single shaft assembly massage part, its default unilateral bearing of mat is just cooperating motor, reverse to, transmission massage part is made the massage functions of different configuration respectively, under this situation, cause its structure very complicated, it is many to form member, the assembling difficulty is time-consuming, thereby the cost height that yields poorly, require each member no-float can transmission smooth and easy simultaneously,, even member is damaged if assembling has careless mistake promptly easily to cause massaging action to have some setbacks slightly, especially under the motor deceleration transmission condition, its excessive torsion will very easily cause thrust bearing to damage and forfeiture separates the effect of action really, influence the smoothness of massaging action, even derive and sell and problem such as maintenance in the future.

The purpose of this utility model is to provide a kind of massage armchair two-way transmission massage mechanism, and it can simplify the assembling of massage mechanism, improves the efficient and the accuracy of action of transmission.

Utility model be achieved in that the housing front side form coaxial independent zones every two vertical axis holes and cooperate upper and lower two groups of location bearings to be installed with two power transmission shafts, two power transmission shafts are the separate transmission kenel, two power transmission shafts respectively a sheathed helical gear, a worm gear and separately with the driven gear engagement of the transverse shaft of correspondence, each rank is established a belt pulley in two ends of power transmission shaft projection outside housing, two belt pulleys are controlled to separate transmission by the just reverse of a motor respectively, just respectively are being arranged with at the two ends of motor penetration type axle, reverse unilateral bearing.Utilize motor just, reverse respectively that power transmission shaft cooperates the different transmission kenels of helical gear or worm gear, and then realize difference in functionality action control to the massage part.

Good effect of the present utility model is:

1, mat dual transmission makes the transmission component of different massage functions can separate assembly, economizes and removes unilateral bearing and thrust bearing, all can significantly simplify at member and fit on, helps improving output, and easy to maintenance;

2, its different massage patterns by motor just, reverse to separate transmission, and the unlikely phase mutual interference of the action of its two power transmission shaft, except that simplifying the transmission component, more can make directly its actuating device of transmission effectively of motor, avoid unnecessary kinetic equation loss, and it moves unlikely interfering with each other, thereby improves the accuracy of transmission efficiency and action.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the two-way transmission massage mechanism of a this utility model massage armchair axonometric exploded view.

Fig. 2 is the two-way transmission massage mechanism combination of a this utility model massage armchair axonometric exploded view.

Fig. 3 is a structural relation sketch map among Fig. 1.

With reference to Fig. 1,2,3, the two-way transmission massage mechanism of massage armchair mainly be with and organize sandwich type element 11,12 hold actuating device, at housing 11,12 front sides form coaxial independent zones every vertical axis hole 13,14 also cooperate, following two groups of location bearings 15,16 are installed with two power transmission shafts 21,22, at two power transmission shafts 21, the sheathed helical gear 23 of 22 difference, one worm gear 24, and at two power transmission shafts 21,22 projections are at housing 11,12 outer each rank of end are established a belt 25,26, housing 11, on 12 rear sides, upper/lower positions respectively is provided with horizontal axis hole 17,18 for two transverse shaft 31,32 wear, two transverse shaft 31,32 respectively the rank be located at the massage part 41,42 two Slave Blocks 43,44 and be suitable eccentric state, in two transverse shaft 31,32 corresponding its power transmission shafts 21,22 position respectively is arranged with driven gear 33,34, use and power transmission shaft 21,22 sheathed helical gears 23 and worm gear 24 mesh respectively and are continuous action relation, at two power transmission shafts 21, the belt pulley 25 that 22 ranks are established, the 26 axle two ends transmissions that are subjected to a motor 27 to provide formula are respectively controlled, and just be with respectively at motor 27 axle two ends, reverse unilateral bearing 28,29, thereby constitute the massage mechanism of two-way actuating device, just utilize motor 27, reverse is to cooperating unilateral bearing 28,29 restriction drives power transmission shaft 21 respectively, 22 and must control the massage part 41, massaging action is beaten or is rubbed in 42 formation, reaches the function of expection.

During use, the reverse of motor 27 drives power transmission shaft 21, the driven gear 33 of the helical gear 23 engaged transmission one sides of power transmission shaft 21, make its interlock transverse shaft 31 establish kenel and following Slave Block 44 is formed the drawing effect according to itself and the off-centre rank of massaging Slave Block 43 on the part 41,42, cause down the massage wheels 45 of Slave Block 44 ends to be action up and down, thereby form the transmission mode of beating massaging action; And below motor 27 is just changeing transmission during power transmission shaft 22, the driven gear 34 of the worm gear 24 engaged transmission one sides of mat power transmission shaft 22, the off-centre rank that makes its interlock transverse shaft 32 comply with 41,42 times Slave Blocks 44 of itself and massage part is established kenel and is rotated about causing its terminal massage wheels 45 to be thereupon, thereby forms the transmission mode of rubbing massaging action.
