AI Technical Summary
Existing vibration motors suffer from problems such as high noise, significant wear, and uncomfortable vibration frequencies during operation.
Multiple inclined cutting surfaces are provided on the fan-shaped eccentric block of the vibratory motor, including a first inclined cutting surface and a second inclined cutting surface. The first inclined cutting surface cuts from the rotation axis to the outer circle edge from the inside to the outside and from high to low. The second inclined cutting surface intersects the cutting direction with the first inclined cutting surface, and the side of the second inclined cutting surface that is close to the rotation axis is a smooth arc-shaped inclined surface.
It reduces wind resistance, makes the motor rotate faster and more smoothly, reduces noise, and improves user comfort through spiral vibration waves.

Description
TECHNICAL FIELD
[0001] The utility model relates to a new type of vibration motor belongs to motor class. BACKGROUND
[0002] With people's increasing demand for medical care equipment, various health physiotherapy equipment are more and more welcomed, such as vibration physiotherapy bed, vibration massage chair and the like, vibration physiotherapy bed mainly utilizes the vibration of vibration motor installed in it to reach certain medical care purposes, the structure of vibration motor is internally installed eccentric block and the like device, how to make vibration motor rotation more stable, low noise, small abrasion, vibration frequency produced more comfortable is the problem that each merchant wants to solve. SUMMARY
[0003] The utility model discloses an improved prior art's insufficient place, provide a novel structure, feel comfortable new type of vibration motor.
[0004] The utility model discloses a technical scheme is: a new type of vibration motor, including the casing, be equipped with the fan -shaped eccentric block in the casing, be equipped with first bevel and second bevel on the fan -shaped eccentric block, first bevel is located at one end of the fan -shaped eccentric block, and first bevel is from the rotation axis of the fan -shaped eccentric block to the outer circle edge and is cut from high to low from inside to outside, and second bevel is located on first bevel, and the cutting direction of second bevel and the cutting direction of first bevel cross, and second bevel is from one side edge to the other side edge from high to low and is cut, and the side edge of second bevel and the rotation axis close to forms the bevel from high to low.
[0005] Further, the bevel from high to low of the side edge of second bevel is the smooth arc bevel.
[0006] Compared with prior art, the utility model discloses the improvement to vibration motor inside, sets up multiple oblique cutting bevel on the fan -shaped eccentric block of vibration motor, and the bevel can reduce the resistance of wind, makes motor rotation faster and more stable, high -efficient and reliable, and the working frequency of motor can be made far from the natural frequency of structure by cutting the eccentric block properly, avoids the excessive vibration of resonance, reduces noise.

[0010] EXPLANATION OF REFERENCE NUMERALS:
[0011] 1 machine shell, 2 fan eccentric block, 201 first chamfer, 202 second chamfer, 203 rotation axis, 204 chamfer.
[0012] The utility model will be described in detail below in combination with the drawings and examples. DETAILED DESCRIPTION
[0013] Referring to Figure 1 、 Figure 2 、 Figure 3 A new type of vibration motor, comprising a machine shell 1, the machine shell 1 is internally provided with a fan eccentric block 2, the fan eccentric block 2 is provided with a first chamfer 201 and a second chamfer 202, the first chamfer 201 is located at one end of the fan eccentric block 2, the first chamfer 201 is chamfered from the rotation axis 203 of the fan eccentric block 2 to the outer circular edge from high to low, the second chamfer 202 is located on the first chamfer 201, the cutting direction of the second chamfer 202 is perpendicular to the cutting direction of the first chamfer 201, as shown in the figure, the second chamfer 202 is chamfered from one side to the other side from high to low, the second chamfer 202 and the side edge close to the rotation axis 203 form a chamfer 204 from high to low, and the chamfer 204 is a smooth arc chamfer.
[0014] The fan eccentric block is provided with multiple chamfers, so that the air resistance can be reduced during operation, the motor can rotate faster and more stably, and the noise is low; in addition, the side edge of the second chamfer 202 and the side edge of the rotation axis 203 form a smooth arc chamfer 204 from high to low, the smooth arc chamfer can make the wind direction spiral upward, can make the motor produce regular spiral vibration waves, the spiral vibration waves have strong penetration, and if the vibration motor is used on a health care instrument such as a physiotherapy bed or a massage chair, the fatigue of the human body can be more eliminated, and the user feels more comfortable.
