[0002] In modern technological products, vibration motors serve as crucial actuators, widely applied across various fields. In consumer electronics, such as smartphones, tablets, and wearable devices, vibration motors provide users with interactive experiences through vibration, including call alerts, message notifications, and game feedback. In industrial settings, vibration motors are used in vibrating screening equipment and material handling equipment, enabling efficient material processing through vibration. In healthcare products, massage devices and similar devices rely on vibration motors to generate vibrations of specific frequencies and intensities to achieve therapeutic or relaxation functions.

[0003] For example, Chinese patent CN217216259U discloses a high-vibration-volume micro vibration motor. Its technical solution includes a micro motor and an eccentric wheel. The output end of the micro motor is fixedly connected to a rotating shaft. The eccentric wheel has a first eccentric hole. The right end of the rotating shaft is splinedly connected to the wall of the first eccentric hole. The eccentric wheel is connected to the right end of the rotating shaft via a fixing component. It also includes a weight-increasing mechanism. The eccentric wheel also has a second eccentric hole, located above the first eccentric hole. The weight-increasing mechanism includes a weight-increasing component and a mounting component. The weight-increasing component is fixedly connected to the bottom of the eccentric wheel via the mounting component. The beneficial effects of this invention are: it can increase the vibration force by increasing the eccentricity and weight of the eccentric wheel. Furthermore, both the eccentricity and the weight of the eccentric wheel are easily adjustable by staff, allowing for flexible adjustment of the vibration force according to the different user needs of different customers.

[0004] However, the aforementioned high-vibration-volume vibration motors have a complex weight-adding structure, resulting in low assembly efficiency that affects usage, and the increase in vibration volume is limited. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a novel vibration motor structure with high vibration volume.

[0006] The specific technical solution is as follows:

[0007] A novel vibration motor structure with high vibration amplitude includes: a vibration component for increasing the vibration amplitude of a micro motor; a drive shaft is fixedly connected to the output end of the micro motor; a mounting hole is provided inside one end of the drive shaft; sliding holes are provided on both the upper and lower surfaces inside the mounting hole; the vibration component is slidably installed in the sliding holes; a baffle is detachably installed at one end of the sliding holes; and silicone blocks are bonded to both the baffle and one end of the inner wall of the sliding holes.

[0008] As a preferred embodiment of this utility model, one end of the inner wall of the mounting hole is provided with a reserved threaded hole, both ends of the baffle are engaged in the sliding hole, and both sides of the baffle are fixedly installed with fitting arc blocks. The fitting arc blocks fit into the mounting hole, one end of the fitting arc block is provided with a through hole, and the through hole is aligned with the reserved threaded hole. The through hole and the reserved threaded hole are internally threaded with a fixing bolt, and the surface of the fixing bolt is coated with thread adhesive.

[0009] As a preferred embodiment of this utility model, the sliding hole is coated with a polytetrafluoroethylene wear-resistant coating.

[0010] As a preferred embodiment of this utility model, the vibration component includes a first T-shaped slider, which is slidably installed in a sliding hole. A second T-shaped slider is detachably installed at one end of the first T-shaped slider. Both the first T-shaped slider and the second T-shaped slider have the same threaded connection hole at one end. A connecting bolt is threaded into the threaded connection hole.

[0012] As a preferred embodiment of this utility model, a counterweight is inserted into the slot, and a metal buckle is installed at one end of the counterweight. The counterweight can be fixed in the slot by being snapped into the buckle groove by the metal buckle. The counterweight is made of tungsten alloy, and the metal buckle is made of nickel-titanium shape memory alloy.

[0013] This utility model has the following beneficial effects:

[0014] 1. The novel high-vibration motor structure provided by this utility model, through the design of the drive shaft, mounting hole, vibration component, and baffle, allows the drive shaft at the output end of the micro motor to start rotating after the micro motor is started. Since the vibration component is slidably installed in the sliding hole within the mounting hole, as the drive shaft rotates, the vibration component will perform centrifugal sliding motion within the sliding hole under the action of centrifugal force, thereby generating vibration and increasing the vibration amount of the motor, multiplying the vibration amplitude to meet the demand for high vibration. Furthermore, the baffle is installed at one end of the sliding hole by fixing bolts to prevent the vibration component from sliding out of the sliding hole. A silicone block is bonded to one end of the baffle and the inner wall of the sliding hole. When the vibration component slides to the end within the sliding hole, the silicone block can act as a buffer, reducing the rigid collision between the vibration component and the baffle and the end of the sliding hole. The polytetrafluoroethylene wear-resistant coating applied inside the sliding hole can reduce the friction between the vibration component and the sliding hole, extending its service life.

[0015] 2. The novel high-vibration motor structure provided by this utility model, through the design of a first T-shaped slider, a second T-shaped slider, connecting bolts, and a counterweight, allows the first and second T-shaped sliders to be connected by the connecting bolts. The upper surfaces of the first and second T-shaped sliders are provided with slots, which can effectively adjust the vibration range by adding or removing tungsten alloy counterweights in the slots or by disassembling the first and second T-shaped sliders. The counterweights are easy to disassemble and use, and the operation is simple with high adjustment accuracy. The vibration range of the vibration motor can be accurately adjusted to a suitable range according to different work requirements. The metal buckle installed at one end of the counterweight makes it easier for workers to add or remove the counterweights. Attached Figure Description

[0029] Example 1

[0030] The novel vibration motor structure with high vibration amplitude provided in this embodiment, such as Figures 1-5 As shown, the device includes: a vibration assembly 3 for increasing the vibration of a micro motor 1; a drive shaft 101 is fixedly connected to the output end of the micro motor 1; a mounting hole 2 is provided inside one end of the drive shaft 101; sliding holes 205 are provided on both the upper and lower surfaces inside the mounting hole 2; the vibration assembly 3 is slidably installed in the sliding hole 205; a baffle 201 is detachably installed at one end of the sliding hole 205; silicone blocks 202 are bonded to one end of both the baffle 201 and the inner wall of the sliding hole 205; a pre-drilled threaded hole 206 is provided at one end of the inner wall of the mounting hole 2; both ends of the baffle 201 are engaged in the sliding hole 205; fitting arc blocks 203 are fixedly installed on both sides of the baffle 201; the fitting arc blocks 203 fit into the mounting hole 2; a through hole is provided at one end of the fitting arc block 203, and the through hole is aligned with the pre-drilled threaded hole 206; a fixing bolt 204 is threadedly connected to the through hole and the pre-drilled threaded hole 206; the surface of the fixing bolt 204 is coated with thread-locking adhesive. The sliding hole 205 is coated with a wear-resistant polytetrafluoroethylene coating.

[0031] Through the design of the drive shaft 101, mounting hole 2, vibration component 3, and baffle 201, after the micro motor 1 is started, the drive shaft 101 at its output end begins to rotate. Since the vibration component 3 is slidably installed in the sliding hole 205 within the mounting hole 2, as the drive shaft 101 rotates, the vibration component 3 will perform centrifugal sliding motion within the sliding hole 205 under the action of centrifugal force, thereby generating vibration to increase the vibration amount of the motor and multiply the vibration amplitude to meet the demand for high vibration. Furthermore, the baffle 201 is secured by fixing bolts 204. Installed at one end of the sliding hole 205, it is used to prevent the vibration component 3 from sliding out of the sliding hole 205. The silicone block 202 is bonded to one end of the baffle 201 and the inner wall of the sliding hole 205. When the vibration component 3 slides to the end in the sliding hole 205, the silicone block 202 can play a buffering role, reducing the rigid collision between the vibration component 3 and the baffle 201 and the end of the sliding hole 205. The polytetrafluoroethylene wear-resistant coating applied inside the sliding hole 205 can reduce the friction between the vibration component 3 and the sliding hole 205 and extend its service life.

[0032] Example 2

[0033] The novel vibration motor structure with high vibration amplitude provided in this embodiment, such as Figures 4-5 As shown, the vibration assembly 3 includes a first T-shaped slider 301, which is slidably installed in a sliding hole 205. A second T-shaped slider 306 is detachably installed at one end of the first T-shaped slider 301. Both the first T-shaped slider 301 and the second T-shaped slider 306 have the same threaded connection hole 307 at one end. A connecting bolt 302 is threaded into the threaded connection hole 307. The connecting bolt 302 is made of titanium alloy and coated with molybdenum disulfide. Both the first T-shaped slider 301 and the second T-shaped slider 306 have a slot 304 at one end of their upper surfaces. A snap-fit ​​groove 305 is provided at one end of the slot 304. A counterweight 303 is inserted into the slot 304. A metal snap-fit ​​308 is installed at one end of the counterweight 303. The counterweight 303 can be snapped into the snap-fit ​​groove 305 and fixed in the slot 304 by the metal snap-fit ​​308. The counterweight 303 is made of tungsten alloy, and the metal snap-fit ​​308 is made of nickel-titanium shape memory alloy.

[0034] Through the design of the first T-shaped slider 301, the second T-shaped slider 306, the connecting bolt 302, and the counterweight 303, the first T-shaped slider 301 and the second T-shaped slider 306 can be connected by the connecting bolt 302. The upper surfaces of the first T-shaped slider 301 and the second T-shaped slider 306 are provided with slots 304, which can effectively adjust the vibration range by adding or removing the tungsten alloy counterweight 303 in the slots 304 or by disassembling and assembling the first T-shaped slider 301 and the second T-shaped slider 306. The counterweight 303 is easy to disassemble and use, and the operation is simple and the adjustment accuracy is high. It can accurately adjust the vibration range of the vibration motor to a suitable range according to different work requirements. The metal buckle 308 installed at one end of the counterweight 303 makes it more convenient for the operator to add or remove the counterweight 303.

[0035] In summary, the novel vibration motor structure with high vibration volume provided in this embodiment has the following advantages: the overall structure is relatively simple, which is convenient for workers to use and avoids the impact on usage efficiency due to disassembly and assembly. Moreover, the vibration component 3 can effectively increase the vibration volume, so as to effectively meet the usage requirements.

[0036] In use, after the micro motor 1 is started, the drive shaft 101 at its output end begins to rotate. Since the first T-shaped slider 301 and the second T-shaped slider 306 are slidably installed in the sliding hole 205 within the mounting hole 2, as the drive shaft 101 rotates, the first T-shaped slider 301 and the second T-shaped slider 306 are connected as a whole by the connecting bolt 302 and move within the sliding hole 205. The counterweight 303 is inserted into the slot 304 and fixed in the buckle slot 305 by the metal buckle 308. 3 can increase the mass of the first T-shaped slider 301 and the second T-shaped slider 306, which can generate a greater centrifugal force when rotating, thereby increasing the amount of vibration. The baffle 201 is installed at one end of the sliding hole 205 by the fixing bolt 204 to prevent the vibration component 3 from sliding out of the sliding hole 205. The silicone block 202 is bonded to one end of the baffle 201 and the inner wall of the sliding hole 205. When the vibration component 3 slides to the end in the sliding hole 205, the silicone block 202 can play a buffering role. The overall structure is convenient to disassemble and use.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
