Description

Technical Field

[0001] This utility model relates to the field of vibrator technology, and in particular to a bidirectional micro linear vibrator. Background Technology

[0002] Linear vibrators are miniature actuators based on the principle of electromagnetic drive. Through the Lorentz force acting on the voice coil in the magnetic field of a permanent magnet, they drive a mass block to reciprocate in a fixed direction. They are characterized by fast response, high energy efficiency, and controllable vibration direction.

[0003] Linear vibrators are used in scenarios such as haptic feedback in smart devices and medical physiotherapy. Due to the limitation of unidirectional vibration function and the significant need for miniaturization of devices, bidirectional vibration output is required to simulate multidimensional tactile sensation and reduce the size to fit portable devices. Bidirectional micro linear vibrators utilize symmetrical magnetic circuits and dual drive coil designs to achieve independent or composite vibration in orthogonal directions, thereby improving the accuracy of interactive experience and meeting the integration requirements of ultra-thin devices.

[0004] However, existing bidirectional miniature linear vibrators have the following shortcomings:

[0005] In the existing technology, bidirectional micro linear vibrators often adopt an integral structure to maintain sealing reliability. However, when internal components fail or deteriorate, the outer shell needs to be cut to carry out repairs or component replacements. In scenarios such as industrial automated production lines and medical high-frequency physiotherapy equipment, vibrators need to vibrate at high frequencies for a long time, which can easily cause spring fatigue or voice coil wear. Regular disassembly and maintenance are required. However, the existing integral shell lacks a detachable design, which leads to complicated maintenance operations and extended equipment downtime.

[0006] Therefore, we propose a bidirectional micro linear vibrator to address the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a bidirectional miniature linear vibrator that utilizes the rapid fixing characteristics of the elastic fixing component to quickly disassemble the linear vibrator. Through the elastic limiting mechanical structure, the locking state of the upper and lower shells can be quickly released, thereby allowing for rapid inspection or replacement of internal components such as springs and voice coils, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a bidirectional micro linear vibrator, comprising a base plate, two fixing plates fixedly connected to the outer wall of the base plate, an embedding groove formed on the top of the base plate, an embedding block movably inserted into the inner wall of the embedding groove, a limiting groove formed on one side of the outer wall of the embedding block, a limiting block movably inserted into the inner wall of the limiting groove, and the outer wall of the limiting block movably inserted inside the base plate, two first springs fixedly connected to the outer wall of the limiting block, and the inner wall of the base plate and the outer walls of the two first springs... The wall is fixedly connected, and the top of the embedded block is fixedly connected to the lower shell. The top of the lower shell has two slots, and the inner surface of each slot is movably fitted with a locking block. The top of the two locking blocks is fixedly connected to the upper shell. The outer surface of the lower shell is fixedly connected to two mounting plates. The inner surface of each mounting plate is fixedly connected to two sets of second springs. The outer surface of each of the four sets of second springs is fixedly connected to a connecting plate. The outer surface of each of the four connecting plates is fixedly connected to a movable frame. The outer surface of each of the four movable frames is fixedly connected to an inclined block.

[0009] Preferably, the top of both mounting plates is provided with a sliding groove, and the inner surface of both sliding grooves is slidably embedded with a slider.

[0010] Preferably, a push plate is fixedly connected to the top of each of the two sliders, and two wedge blocks are fixedly connected to the outer wall of each of the two push plates.

[0011] Preferably, thermally conductive silicone pads are adhered to the top of the two upper shells, and a heat-conducting plate is fixedly connected to the top of the thermally conductive silicone pads.

[0012] Preferably, a heat dissipation fin is fixedly connected to the top of the heat-conducting plate, and a protective box is fixedly connected to the top of the upper shell.

[0013] Preferably, the outer wall of the protective box has multiple sets of ventilation holes on one side.

[0014] Preferably, two miniature cooling fans are fixedly installed on one side of the outer wall of the protective box.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the linear vibrator can be quickly disassembled by utilizing the rapid fixing characteristics of the elastic fixing component. At the same time, through the elastic limiting mechanical structure, the locking state of the upper shell and the lower shell can be quickly released, thereby quickly inspecting or replacing internal components such as springs and voice coils. In this way, the linear vibrator can be quickly disassembled and the outer shell can be separated without damage, making the maintenance and component replacement of the vibrator more convenient and efficient. The disassembly and assembly operations are simple and easy to perform, significantly shortening the maintenance operation time and reducing equipment downtime.

[0017] 2. In this utility model, through the interaction of the various components of the device, efficient heat dissipation of the linear vibrator is achieved, ensuring that the linear vibrator can effectively dissipate the heat generated by the energization of the voice coil and mechanical friction during long-term high-frequency vibration, thereby maintaining the safe operating temperature of the internal components and avoiding performance degradation or failure risk caused by temperature rise.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: a bidirectional micro linear vibrator, including a base plate 1, two fixing plates 2 fixedly connected to the outer wall of the base plate 1, an embedding groove 3 opened on the top of the base plate 1, an embedding block 4 movably inserted into the inner wall of the embedding groove 3, a limiting groove 5 opened on one side of the outer wall of the embedding block 4, a limiting block 6 movably inserted into the inner wall of the limiting groove 5, and the outer wall of the limiting block 6 movably inserted into the interior of the base plate 1, two first springs 7 fixedly connected to the outer wall of the limiting block 6, and the inner wall of the base plate 1 fixedly connected to the outer walls of the two first springs 7, a lower shell 8 fixedly connected to the top of the embedding block 4, two slots 9 opened on the top of the lower shell 8, and the inner walls of the two slots 9 are movable. A locking block 10 is inserted, and an upper shell 11 is fixedly connected between the tops of two locking blocks 10. Two mounting plates 12 are fixedly connected to the outer wall of the lower shell 8. Two sets of second springs 13 are fixedly connected to the inner wall of each of the two mounting plates 12. Connecting plates 14 are fixedly connected between the outer walls of the four sets of second springs 13. A movable frame 15 is fixedly connected to one side of the outer wall of each of the four connecting plates 14. An inclined block 16 is fixedly connected to the outer wall of each of the four movable frames 15. A sliding groove 17 is opened on the top of each of the two mounting plates 12. A slider 18 is slidably embedded in the inner wall of each of the two sliding grooves 17. A push plate 19 is fixedly connected to the top of each of the two sliders 18. Two wedge blocks 20 are fixedly connected to the outer wall of each of the two push plates 19.

[0026] The effect achieved by the entire embodiment 1 is as follows: During use, when it is necessary to disassemble the linear vibrator for maintenance and replacement of internal components such as springs and voice coils, first pull the limiting block 6 to disengage it from the limiting groove 5, release the fixed constraint of the embedded block 4 and the vibrator, and the vibrator can be taken out. At this time, the operator presses the two push plates 19, and the two push plates 19 drive the four wedge blocks 20 to move synchronously. After the inclined surfaces of the four wedge blocks 20 contact the inclined surfaces of the four inclined blocks 16, the inclined blocks 16 are pushed outward by the horizontal force, and drive the four moving frames 15 to move outward synchronously, so that the protrusions on the top of the four moving frames 15 disengage from the limiting of the upper shell 11, thereby quickly disassembling the upper shell 11 and inspecting or replacing the internal components. In this way, the maintenance operation is made convenient and the maintenance efficiency is significantly improved.

[0027] Example 2, as Figure 2-4 As shown, thermal conductive silicone pads 21 are attached to the top of the two upper shells 11, and thermal conductive plates 22 are fixedly connected to the top of the thermal conductive silicone pads 21. Heat dissipation fins 23 are fixedly connected to the top of the heat dissipation plates 22. A protective box 24 is fixedly connected to the top of the upper shells 11. Multiple sets of ventilation holes 25 are opened on one side of the outer wall of the protective box 24. Two miniature cooling fans 26 are fixedly installed on one side of the outer wall of the protective box 24.

[0028] The overall effect of Embodiment 2 is as follows: During the long-term use of the linear vibrator, a large amount of heat is generated due to the electromagnetic loss of the voice coil and the friction of mechanical parts. At this time, the heat is conducted outward through the outer shell 11. The thermally conductive silicone pad 21 can fill the contact gap and improve the heat conduction efficiency. The heat-conducting plate 22 further collects the heat and conducts it evenly to the heat dissipation area. The heat dissipation fins 23 on one side of the outer wall of the heat-conducting plate 22 can further expand the heat dissipation surface area. By starting two micro cooling fans 26, the fans generate suction force, which creates a negative pressure environment inside the protective box 24. Cold air from the outside enters the protective box 24 through multiple sets of vents 25, thereby causing the airflow to force convection cooling of the heat dissipation fins 23, thus causing the temperature to drop rapidly. Through this airflow organization that combines heat conduction and air intake, the heat is efficiently discharged to the external environment, thereby ensuring that the linear vibrator maintains a stable operating temperature and long-term reliable performance.

[0029] The working principle of the entire device is as follows: In use, firstly, the two fixing plates 2 and the base plate 1 are fixed to the target structure surface where vibration is required using screws, thus fixing the vibrator in the preset installation position. When the linear vibrator needs to be disassembled for internal maintenance, first pull the limiting block 6 to disengage it from the limiting groove 5, releasing the fixing constraint of the embedded block 4 and the vibrator, allowing the vibrator body to be removed. At this time, the operator presses the two push plates 19, which drive the four wedge blocks 20 to move synchronously. After the inclined surface of the wedge block 20 contacts the inclined surface of the four inclined blocks 16, the inclined blocks 16 are pushed outward by lateral force, driving the four moving frames 15 to move outward synchronously, causing the protrusions of the moving frames 15 to disengage from the limiting lock on the upper shell 11, thereby quickly disassembling the upper shell. Shell 11 is used to inspect or replace core components such as internal springs and voice coils. During the long-term operation of the linear vibrator, a large amount of heat will accumulate due to the Joule heat generated by the energized voice coil and the frictional wear of mechanical parts. The heat is slowly dissipated outward through the shell 11. Thermal conductive silicone pads 21 can fill the gaps between components and improve the heat conduction efficiency. Heat-conducting plates 22 further gather heat and evenly conduct it to the heat dissipation area. The heat dissipation fins 23 on its outer wall can significantly expand the heat exchange surface area. After the two micro cooling fans 26 are activated, a strong suction airflow is generated, which creates a negative pressure state inside the protective box 24. Cold air from the outside flows in quickly through multiple sets of vents 25. The airflow forces the heat dissipation fins 23 to cool down, effectively reducing the overall temperature.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
