Description

Technical Field

[0001] The utility model relates to the technical field of massage equipment, in particular to a neck massager movement with high transmission efficiency. Background Art

[0002] A neck massager is a massage device that simulates manual massage on the neck through a massage head. It can relax the neck muscles and prevent cervical diseases. Specifically, the neck massager drives the massage head to swing along a set trajectory through a motor to achieve the function of rubbing and kneading the human neck. The massage head needs to provide a large torque from the motor when kneading to ensure that the neck massager has better massage strength and massage effect.

[0003] In order to avoid uneven weight distribution on both sides of the neck massager, which causes uneven force on both sides of the neck and affects the massage effect. At the same time, the horizontally arranged motor is subject to the size limit and power requirement of the neck massager, and the motor needs to maintain a large radial size, which makes the size of the neck massager larger. The increase in size will lead to an increase in the weight of the neck massager, which further affects the massage effect of the neck massager. Therefore, the motor is generally installed vertically, and then a multi-stage transmission is used to provide power for the massager.

[0004] In the prior art, a three-stage gear transmission structure is used, which uses a worm gear to drive a parallel shaft spur gear, and finally uses a bevel gear to drive the eccentric wheel. With the three-stage transmission structure, the size of the gear box is large, and there is less rubber filling between the outer casing and the gear box, resulting in a harder exterior, which can easily make the user feel uncomfortable. In addition, the above-mentioned transmission method has a complex structure, and the parts are difficult to process, which makes assembly difficult, and the transmission efficiency of the bevel gear is low.

[0005] In view of this, a neck massager movement with high transmission efficiency is urgently needed to solve the above problems. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A neck massager movement with high transmission efficiency comprises: a mounting shell, a rotating shaft and a motor, wherein the rotating shaft is rotatably arranged in the mounting shell, the motor is installed in the mounting shell, and the axial direction of the output shaft of the motor is perpendicular to the axial direction of the rotating shaft;

[0009] A first double gear is rotatably arranged in the mounting shell, a worm is coaxially arranged on the output shaft of the motor, a transmission gear is sleeved on the rotating shaft, one end of the first double gear is meshed with the worm, and the other end of the first double gear is meshed with the transmission gear;

[0010] Both ends of the rotating shaft are provided with eccentric components.

[0011] Its further characteristic is that

[0012] One end of the large-diameter gear of the first duplex gear is meshed with the worm, and one end of the small-diameter gear of the first duplex gear is meshed with the transmission gear.

[0013] The eccentric assembly comprises an eccentric wheel and a swing sleeve. The eccentric wheel is sleeved on the end of the rotating shaft. The axial direction of the eccentric wheel is different from the axial direction of the rotating shaft. The swing sleeve is sleeved on the eccentric wheel.

[0014] The swing sleeve comprises a collar and a swing arm arranged on the collar surface, and the collar is sleeved on the eccentric wheel.

[0015] The mounting shell is provided with guide seats on both sides of the end of the rotating shaft, and waist-shaped holes are opened on the guide seats. Two guide rods are arranged opposite to each other on the annular surface of the sleeve ring, and the guide rods are movably arranged in the corresponding waist-shaped holes.

[0016] The two collars are provided with an eccentric cover for fixing the collars on the eccentric wheel on the sides away from each other. The eccentric cover is fixed on the eccentric wheel by bolts.

[0017] Both ends of the rotating shaft are provided with E-shaped clamping springs.

[0018] The axial direction of the first double gear is the same as the axial direction of the rotating shaft.

[0019] Two supporting seats are arranged in the installation shell, and the rotating shaft is placed on the two supporting seats.

[0020] The motor is a brushless motor.

[0021] The above structure of the utility model can achieve the following beneficial effects:

[0022] The power of the motor is transmitted to the rotating shaft through the first double gear and the worm, so that the eccentric components located at both ends of the rotating shaft move. Firstly, only two-stage transmission is adopted. Due to the fewer structures, the size of the gear box is smaller, and more rubber cotton can be filled between the gear box and the outer shell, making the massager softer and bringing a better experience to the user. Secondly, the transmission efficiency of the two-stage transmission of the present application is higher than that of the bevel gear transmission efficiency, and the double gear has the advantages of low processing and manufacturing difficulty, low cost and easy installation compared with the double bevel gear.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] like Figure 1-3As shown, a neck massager movement with high transmission efficiency includes: a mounting shell 1, a rotating shaft 2 and a motor 3, the rotating shaft 2 is rotatably arranged in the mounting shell 1, the motor 3 is installed in the mounting shell 1, and the axial direction of the output shaft of the motor 3 is perpendicular to the axial direction of the rotating shaft 2; a first double gear 4 is rotatably arranged in the mounting shell 1, a worm 5 is coaxially arranged on the output shaft of the motor 3, a transmission gear 6 is sleeved on the rotating shaft 2, one end of the first double gear 4 is meshed with the worm 5, and the other end of the first double gear 4 is meshed with the transmission gear 6; both ends of the rotating shaft 2 are provided with eccentric components, so that The power of the motor 3 is transmitted to the rotating shaft 2 through the first double gear 4 and the worm 5, so that the eccentric components located at both ends of the rotating shaft 2 move. First, only two-stage transmission is adopted. Due to the small number of structures, the gear box is smaller in size, and more rubber cotton can be filled between the gear box and the shell, making the massager softer and bringing a better experience to the user. Secondly, the transmission efficiency of the two-stage transmission of the present application is higher than that of the bevel gear transmission, and the double gear (helical gear plus spur gear) has the advantages of low processing and manufacturing difficulty, low cost and easy installation compared to the double bevel gear.

[0033] Among them, Figure 2-3 As shown, one end of the large diameter gear (helical gear) of the first double gear 4 is meshed with the worm 5, and one end of the small diameter gear (spur gear) of the first double gear 4 is meshed with the transmission gear 6. The axial direction of the first double gear 4 is the same as the axial direction of the rotating shaft 2. In this way, the motor power is transmitted to the rotating shaft 2, and the speed reduction effect can be achieved.

[0034] Among them, Figure 2-5 As shown, the eccentric assembly includes an eccentric wheel 7 and a swing sleeve. The eccentric wheel 7 is sleeved on the end of the rotating shaft 2. The axial direction of the eccentric wheel 7 is different from the axial direction of the rotating shaft 2. The swing sleeve is sleeved on the eccentric wheel 7. The swing sleeve includes a collar 8 and a swing arm 9 arranged on the annular surface of the collar 8. The collar 8 is sleeved on the eccentric wheel 7. The mounting shell 1 is provided with guide seats 11 on both sides of the end of the rotating shaft 2. The guide seats 11 are provided with waist-shaped holes. Two guide rods 81 are relatively arranged on the annular surface of the collar 8. The guide rods 81 are movably arranged in the corresponding waist-shaped holes. In this way, by setting the eccentric wheel 7 with an axial direction different from that of the rotating shaft 2, the swing sleeve is driven to move under the restriction of the waist-shaped hole, thereby driving the massage head installed on the swing sleeve to move.

[0035] Among them, Figure 2-3 As shown, the two sides of the two collars 8 that are away from each other are each provided with an eccentric cover 71 for fixing the collar 8 on the eccentric wheel 7. The eccentric cover 71 is fixed to the eccentric wheel 7 by bolts, and both ends of the rotating shaft 2 are provided with E-type retaining springs 21. In this way, the swing sleeve is fixed to the eccentric wheel 7 by bolts and the eccentric cover 71, and the eccentric assembly is fixed to the rotating shaft 2 by the E-type retaining spring 21, which makes assembly easier.

[0036] Among them, Figure 2As shown, two support seats 12 are arranged in the mounting shell 1, and the rotating shaft 2 is placed on the two support seats 12. In this way, the support seats 12 are arranged to support the rotating shaft 2 for rotation.

[0037] It is further optimized that the motor 3 is a brushless motor.

[0038] In summary, the power of the motor 3 is transmitted to the rotating shaft 2 through the first double gear 4 and the worm 5, so that the eccentric components located at both ends of the rotating shaft 2 move. First of all, only two-stage transmission is adopted. Due to the small structure, the gear box is smaller in size, and more rubber cotton can be filled between the gear box and the outer shell to make the massager softer and bring a better experience to the user. Secondly, the transmission efficiency of the two-stage transmission of the present application is higher than that of the bevel gear transmission, and the double gear (helical gear plus spur gear) has the advantages of low processing and manufacturing difficulty, low cost and easy installation compared to the double bevel gear.

[0039] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
