Description

Technical Field

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

[0002] A vibrator is a device that converts electrical energy, mechanical energy, or other forms of energy into vibrational energy. It generates periodic mechanical vibrations to meet the needs of various industrial, engineering, daily life, and medical fields.

[0003] Electronic linear vibrators mainly rely on the electromagnetic force between the magnet and the coil to generate linear motion to achieve vibration. They lack dedicated components for dissipating vibration energy and reducing the amplitude of the object. When the vibrator is started, the vibration energy is difficult to dissipate quickly, resulting in the vibration not being eliminated in a short time. Long-term exposure to vibration will accelerate the wear of internal components. This wear will not only shorten the service life of the equipment but may also cause equipment failure, preventing the equipment from working properly and thus affecting the efficiency of the entire system. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the above-mentioned equipment cannot quickly eliminate vibration during use, which affects the normal operation and lifespan of the equipment, and thus proposes an electronic linear vibrator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electronic linear vibrator, including a housing;

[0006] Multiple cylinders are used to store the relevant structures;

[0007] Multiple electromagnets are installed on one side of the inner wall of the cylinder to drive the displacement of related structures;

[0008] Multiple permanent magnets are inserted inside the cylinder and work together with the electromagnet to form a primary shock absorption mechanism.

[0009] Multiple dampers are fixedly installed on one side of the outer wall of the permanent magnet II, which effectively weakens the vibration of the vibrator when vibration reduction is required. Spring II is fixedly installed between the inner walls of the multiple dampers, which cooperate with the dampers to achieve two-stage vibration reduction.

[0010] When the user needs to dampen the vibrator, they can energize the electromagnet. At this time, the electromagnet generates a magnetic pole opposite to that of the second permanent magnet. Under the repulsive force of like poles, the second permanent magnet and the damper fixed on one side of the outer wall are pushed out of the cylinder. The electromagnet and the second permanent magnet form a primary magnetic damping structure. The damper and the second internal spring form a secondary damping structure. When the moving block moves left and right and comes into contact with the damper, it will push the damper to contract and squeeze the second internal spring, causing it to absorb the kinetic energy of the moving block. At the same time, the damper as a whole will also move, pushing the second permanent magnet closer to the electromagnet. The mutual repulsion of the magnetic forces between the two also has a good damping effect. This device can effectively reduce the vibration of the vibrator when needed. By reducing vibration stress, it reduces the wear of the internal equipment caused by excessive vibration, thus extending the equipment's lifespan. In scenarios where rapid start and stop of vibration is required, the damping mechanism can suppress residual vibration and improve the clarity of related tactile feedback.

[0011] Preferably, two springs are fixedly installed on the inner wall of the outer shell, and a movable block is fixedly installed between the outer walls of the two springs. A permanent magnet is fixedly inserted inside the movable block. Two mounting pieces are adhered to the inner wall of the outer shell, and a set of coils is adhered to one side of the outer wall of each of the two mounting pieces. The two sets of coils are alternately energized, and the positive and negative poles generated guide the permanent magnet to move back and forth continuously, thereby driving the movable block to move rapidly and generate vibration.

[0012] Preferably, baffles are fixedly inserted into the inner walls of the plurality of cylinders, and the inner walls of the plurality of baffles are movably inserted into the outer walls of the permanent magnet II. Two mounting seats are fixedly installed on the outer walls of the outer shell, and threaded holes are opened on the top of the two mounting seats. The mounting seats are located on both sides of the outer shell and are used to fix the position of the outer shell.

[0013] Preferably, the inner walls of the four threaded holes are all threaded with fixing bolts, and the tops of the two mounting seats are all fixedly installed with positioning seats. After the fixing bolts are screwed into the threaded holes, the outer shell can be quickly and stably fixed.

[0014] Preferably, each of the four fixing bolts has a set of mounting grooves on its outer wall, and a spring is fixedly installed on one side of the inner wall of each of the four sets of mounting grooves. The mounting grooves can accommodate the corresponding structures, and the springs can reposition the relevant structures by compression and contraction.

[0015] Preferably, each of the four sets of springs has a locking block fixedly installed on one side of its outer wall. The inner surface of each of the four sets of mounting grooves is movably inserted into the outer surface of the locking block. When the fixing bolt rotates and descends, people can first squeeze the locking block to make it squeeze the spring three back into the mounting groove. As the fixing bolt is fully screwed in, the locking block begins to release its restraint, and the spring three will drive the locking block to insert into the positioning seat, preventing the fixing bolt from falling off due to vibration, which would cause the vibrator to be unstable.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the device guides a permanent magnet to reciprocate through two sets of coils alternately energized, causing a moving block to vibrate. When vibration damping is required, an electromagnet can be energized. The electromagnet and the permanent magnet move away from each other to form a primary magnetic damping structure. The damper and the internal spring form a secondary damping structure. When the moving block contacts the damper, the spring absorbs kinetic energy, and the magnetic repulsion also plays a damping role. This effectively reduces the vibration of the vibrator and lowers the vibration stress. The two systems respond in tandem, which can reduce a large amount of vibration stress during equipment operation, effectively reduce component wear and extend equipment life. It can quickly suppress residual vibration during start-up and shutdown. At the same time, the intelligent start-up and shutdown of the damping system is realized through the on / off control of the electromagnet, taking into account both vibration efficiency and equipment protection requirements.

[0029] Multiple permanent magnets 10 are inserted inside the cylinder 7 and cooperate with the electromagnet 8 to form a primary shock absorption mechanism;

[0030] Multiple dampers 11 are fixedly installed on one side of the outer wall of permanent magnet 10, which effectively weakens the vibration of the vibrator when vibration reduction is required. Springs 12 are fixedly installed between the inner walls of multiple dampers 11, which cooperate with the dampers 11 to achieve two-stage vibration reduction.

[0031] When the user needs to dampen the vibrator, the electromagnet 8 can be energized. At this time, the electromagnet 8 generates a magnetic pole opposite to that of the permanent magnet 10. Under the repulsive force of like poles, the permanent magnet 10 and the damper 11 fixed on one side of the outer wall are pushed out of the cylinder 7. The electromagnet 8 and the permanent magnet 10 form a primary magnetic damping structure. The damper 11 and the internal spring 12 form a secondary damping structure. When the left-right moving block 3 contacts the damper 11, it will push the damper 11 to contract and squeeze the internal spring 12, so that it absorbs the kinetic energy of the moving block 3. At the same time, the damper 11 will also move as a whole, pushing the permanent magnet 10 closer to the electromagnet 8. The mutual repulsion of the magnetic forces between the two also has a good damping effect. This device can effectively reduce the vibration of the vibrator when needed. By reducing vibration stress, it reduces the wear of the internal equipment caused by excessive vibration, thus extending the equipment life. In scenarios where rapid start and stop of vibration is required, the damping mechanism can suppress residual vibration and improve the clarity of related tactile feedback.

A permanent magnet 4 is fixedly inserted inside the movable block 3. Two mounting pieces 5 are adhered to the inner wall of the outer shell 1. A set of coils 6 is adhered to one side of the outer wall of each of the two mounting pieces 5. The two sets of coils 6 are alternately energized. Through the positive and negative poles generated, the permanent magnet 4 is guided to move back and forth continuously, thereby driving the movable block 3 to move rapidly and generate vibration.

[0033] like Figures 1-2 As shown, baffles 9 are fixedly inserted into the inner walls of multiple cylinders 7, and the inner walls of multiple baffles 9 are movably inserted into the outer walls of permanent magnet 10. Two mounting seats 13 are fixedly installed on the outer walls of the outer shell 1. Threaded holes 14 are opened on the top of the two mounting seats 13. The mounting seats 13 are located on both sides of the outer shell 1 and are used to fix the position of the outer shell 1.

[0034] like Figures 1-4 As shown, the inner walls of the four threaded holes 14 are all threaded with fixing bolts 15, and the tops of the two mounting seats 13 are all fixedly installed with positioning seats 16. After the fixing bolts 15 are screwed into the threaded holes 14, the outer shell 1 can be quickly and stably fixed.

[0035] like Figure 1 as well as Figure 4 As shown, each of the four fixing bolts 15 has a set of mounting grooves 17 on its outer wall. Each of the four sets of mounting grooves 17 has a spring 18 fixedly installed on one side of its inner wall. The mounting grooves 17 can accommodate the corresponding structures, and the springs 18 can reposition the relevant structures by compression and contraction.

[0036] like Figure 4 As shown, each of the four sets of springs 18 has a locking block 19 fixedly installed on one side of its outer wall. The inner surface of each of the four sets of mounting grooves 17 is movably inserted into the outer surface of the locking block 19. When the fixing bolt 15 rotates down, people can first squeeze the locking block 19 to make it squeeze the spring 18 back into the mounting groove 17. As the fixing bolt 15 is fully screwed in, the locking block 19 begins to release its restraint, and the spring 18 will drive the locking block 19 to insert into the positioning seat 16, preventing the fixing bolt 15 from falling off due to vibration, which would cause the vibrator to be unstable.
