[0002] A vibratory motor has a set of adjustable eccentric blocks installed at both ends of the rotor shaft. The vibration force is obtained by using the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks.

[0003] Existing vibratory motors have the following drawbacks during use: Adjusting the amplitude of the vibratory motor is cumbersome, requiring disassembly of the outer casing and subsequent removal of the eccentric wheel with a wrench, which is time-consuming and labor-intensive. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is: a waterproof vibration motor, including: a main body mechanism and an eccentric mechanism, wherein the main body mechanism includes a vibration motor body, a first rotating shaft installed in the inner cavity of the vibration motor body and extending out of the vibration motor, and a first eccentric block fixed on the first rotating shaft.

[0006] The eccentric mechanism includes end caps fixed on both sides of the vibratory motor body, bearings fixed on the inner wall of the end caps, a second rotating shaft fixed on the inner ring of the bearing, a second eccentric block fixed on the second rotating shaft, a connector movably fitted into the inner cavity of the second rotating shaft with one end extending out of the end cap and the other end fitted into the first rotating shaft, and a sealing cap installed on one side of the end cap by a threaded connection.

[0007] The end cap has multiple trapezoidal annular grooves on its side, and a sealing ring is provided inside the trapezoidal annular groove, with a portion of the sealing ring extending outward from the trapezoidal annular groove.

[0008] In a preferred embodiment, the present invention can be further configured such that: the end of the first rotating shaft has a first spline groove, and the end of the second rotating shaft has a second spline groove.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the connecting member includes a spline shaft movably fitted in the second spline groove, a cross connecting rod with one end fixed to the spline shaft and the other end extending out of the second rotating shaft, a circular plate fixed to the end of the cross connecting rod, and a spring with one end connected to the spline shaft and the other end fixedly connected to the bottom wall of the second spline groove. One end of the spline shaft is fitted in the second spline groove, and the other end is fitted in the first spline groove.

[0010] In a preferred embodiment, the present invention can be further configured such that: a ring-shaped scale is fixed on one side of the end cap, and a pointer is fixed on the end of the second rotating shaft extending out of the end cap, with the pointer located on one side of the ring-shaped scale.

[0011] In a preferred embodiment, the present invention can be further configured such that: threaded holes are arranged in a ring array on both sides of the vibratory motor body, and bolts are arranged in a ring array on one side of the end cover, with the bolts passing through the periphery of the end cover and engaging in the threaded holes.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, a first eccentric block is installed at the end of the shaft of the vibratory motor, and a first spline groove is formed at the end of the shaft. A bearing is fixed on the inner wall of the end cover, and a second shaft extending out of the end cover is fixed on the inner ring of the bearing. The second eccentric block is fixed on the second shaft. A connecting piece extending into the first spline groove is movably arranged in the inner cavity of the rotating seat. With the above arrangement, when it is necessary to adjust the amplitude of the vibratory motor, simply pull the connecting piece outward to disconnect the connection between the first and second shafts. Rotating the connecting piece will then drive the second shaft to rotate. The rotation of the two shafts drives the second eccentric block to rotate, thereby adjusting the angle between the first and second eccentric blocks. The larger the angle, the larger the amplitude; the smaller the angle, the smaller the amplitude. After adjustment, the connecting piece is loosened to connect the first and second shafts. There is no need to disassemble the end cover of the vibration motor, and the eccentric block can be adjusted directly, which effectively increases the convenience of using the vibration motor. In addition, a pointer is provided at the end of the shaft, and a ring scale is provided on the outer surface of the end cover, which allows for accurate observation of the adjustment angle when adjusting the second eccentric block.

[0014] 2. In this utility model, two trapezoidal annular grooves are opened at the end of the end, and a sealing ring is set inside the trapezoidal annular groove. This setting effectively increases the sealing between the end cover and the vibrating motor body and improves the waterproof performance of the vibrating motor. In addition, a sealing cover is installed in the middle of the end cover by threaded connection to prevent water from entering the inner cavity of the end cover through the gap between the second rotating shaft and the end cover.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0025] Combination Figure 1-5 As shown, this embodiment provides a waterproof vibration motor, including: a main body mechanism 100 and an eccentric mechanism 200.

[0026] The main body 100 includes a vibration motor body 110, a first rotating shaft 120 installed in the inner cavity of the vibration motor body 110 and extending out of the vibration motor, and a first eccentric block 130 fixed on the first rotating shaft 120.

[0027] The vibratory motor body 110 is used to mount the first rotating shaft 120 and drive the first rotating shaft 120 to rotate. The first rotating shaft 120 passes through the rotor of the vibratory motor body 110 and is fixed thereto, so that the rotor can drive the first rotating shaft 120 to rotate. The first eccentric block 130 is fixed on the end of the first rotating shaft 120, so that when the first rotating shaft 120 rotates, the centrifugal force generated by the high-speed rotation of the first eccentric block 130 can be used to obtain the excitation force, thereby generating vibration.

[0028] The eccentric mechanism 200 includes end caps 210 fixed on both sides of the vibratory motor body 110, bearings 220 fixed on the inner wall of the end caps 210, a second rotating shaft 230 fixed on the inner ring of the bearings 220, a second eccentric block 240 fixed on the second rotating shaft 230, a connector 250 movably fitted into the inner cavity of the second rotating shaft 230 with one end extending out of the end caps 210 and the other end fitted into the first rotating shaft 120, and a sealing cap 260 installed on one side of the end caps 210 by a threaded connection.

[0029] The end cap 210 is used to protect the first eccentric block 130 and the second eccentric block 240 from interference from the external environment when they rotate. Threaded holes 111 are arranged in a ring array on both sides of the vibratory motor body 110, and bolts 213 are arranged in a ring array on one side of the end cap 210. The bolts 213 pass through the periphery of the end cap 210 and engage in the threaded holes 111 to fix the end cap 210 to the vibratory motor body 110.

[0030] In addition, multiple trapezoidal annular grooves 211 are opened on the side of the end cover 210. A sealing ring 212 is provided inside the trapezoidal annular groove 211. A part of the sealing ring 212 extends outward from the trapezoidal annular groove 211. When the end cover 210 and the vibration motor are fixedly connected by bolts 213, the sealing ring 212 is located between the two to ensure the sealing between them and effectively improve the waterproof performance of the vibration motor.

[0031] A tube body is fixed on the inner side of the end cap 210. The outer ring of the bearing 220 is fixed on the inner wall of the tube body. The inner ring of the bearing 220 is fixed with a second rotating shaft 230 to ensure that the second rotating shaft 230 can rotate stably. The second eccentric block 240 is fixed on the second rotating shaft 230 and has the same function as the first eccentric block 130.

[0032] A first spline groove 121 is formed at the end of the first rotating shaft 120, and a second spline groove 231 is formed at the end of the second rotating shaft 230. The connecting member 250 includes a spline shaft 251 that is movably fitted into the second spline groove 231, a cross connecting rod 252 with one end fixed to the spline shaft 251 and the other end extending out of the second rotating shaft 230, a circular plate 253 fixed to the end of the cross connecting rod 252, and a spring 254 with one end connected to the spline shaft 251 and the other end fixedly connected to the bottom wall of the second spline groove 231. One end of the spline shaft 251 is fitted into the second spline groove. Inside 231, the other end is fitted into the first spline groove 121, so that when the first rotating shaft 120 rotates, it drives the second rotating shaft 230 to rotate synchronously through the spline shaft 251, thereby driving the first eccentric block 130 and the second eccentric block 240 to rotate synchronously. The cross connecting rod 252 connects the spline shaft 251 and the circular plate 253. The circular plate 253 allows the user to easily pull the spline shaft 251 from the outside of the end cover 210 to move it. The spring 254 can ensure that the end of the spline shaft 251 is fitted into the first spline groove 121 on the first rotating shaft 120.

[0033] In addition, an annular scale 214 is fixed on one side of the end cover 210, and a pointer 232 is fixed on the end of the second rotating shaft 230 that extends out of the end cover 210. The pointer 232 is located on one side of the annular scale 214. With this setting, the user can observe the rotation angle of the second rotating shaft 230, that is, the adjustment angle of the second eccentric block 240.

[0034] The sealing cap 260 is installed on one side of the end cap 210 by a threaded connection, which can seal the part of the second rotating shaft 230 that extends out of the end cap 210 and prevent water from entering the end cap 210.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the amplitude of the vibration motor body, unscrew the sealing cover 260 and pull the circular plate 253 outward. The movement of the circular plate 253 drives the spline shaft 251 outward through the cross connecting rod 252, causing the end of the spline shaft 251 to disengage from the first spline groove 121 on the first rotating shaft 120, thus disconnecting the connection between the first rotating shaft 120 and the second rotating shaft 230. At this time, rotating the circular plate 253 causes the cross connecting rod 252 and the spline shaft 251 to rotate, which in turn drives the second rotating shaft 230 to rotate. Rotating the first eccentric wheel 30 causes the second eccentric wheel to rotate, adjusting the angle between the first and second eccentric wheels. The larger the angle, the larger the amplitude; the smaller the angle, the smaller the amplitude. The angle adjustment is monitored by the rotation of the pointer 232 on the annular scale 214. After adjustment, the circular plate 253 is released. Under the action of the spring 254, the spline shaft 251 extends out from the second spline groove 231 inside the second rotating shaft 230 and fits into the first spline groove 121 at the end of the first rotating shaft 120, completing the connection between the first rotating shaft 120 and the second rotating shaft 230. Then, the sealing cover 260 is screwed on.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
