Description

Technical Field

[0001] This invention relates to the field of vibration motor technology, and in particular to a highly sensitive and high-vibration-sensitivity flat vibration motor. Background Technology

[0002] A vibratory motor is an excitation source that integrates a power source and a vibration source. It consists of adjustable eccentric blocks installed at both ends of the rotor shaft. The excitation force is generated by the centrifugal force produced by the high-speed rotation of the shaft and eccentric blocks. Vibratory motors offer high excitation force utilization, low energy consumption, low noise, and long service life. The excitation force of a vibratory motor is steplessly adjustable, making it easy to use. It can be applied to general vibrating machinery and is widely used in hydropower construction, thermal power generation, construction, building materials, chemical industry, mining, coal, metallurgy, light industry, and other industrial sectors.

[0007] Preferably, the lower seat and the upper cover are provided with permanent magnets. The permanent magnets are rectangular in shape and located between the two mating seats. Rectangular grooves are provided on both outer walls of the permanent magnets. An auxiliary seat is fixedly connected to the inner wall of the rectangular groove.

[0009] Preferably, each end of the permanent magnet is fixedly connected to a clamping block, and each clamping block is fixedly connected to two symmetrical push seats on one side of its outer wall. Each push seat is fixedly connected to a push rod on one side of its outer wall, and the other end of the push rod is fixedly connected to a pressure seat.

[0010] Preferably, a central partition ring is fixedly connected to the outside of the push rod, the central partition ring is located between the push seat and the pressure seat, and a return spring is sleeved on the outside of the push rod.

[0012] Preferably, the inner walls of the lower seat and the upper cover are provided with rectangular grooves. The two rectangular grooves are symmetrically distributed on the upper and lower sides of the permanent magnet. The inner walls of the two rectangular grooves are fixedly connected with insulating plates, and multiple coils are fixedly connected to the outer wall of the insulating plate on the side closest to the permanent magnet. The multiple coils are equidistantly distributed.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention, through the design of a lower seat, upper cover, fitting seat, suction cup, airflow control valve, air supply pipe, and air nozzle, allows for precise installation. During installation, the lower seat presses against the mounting surface, and the external suction pipe is inserted into the air nozzle for suction. The suction cup then adheres more deeply to the mounting surface, removing any accumulated air until the fitting seat is fully in contact with the inner wall of the lower seat. The device is then bolted in place. The movable fitting seat and suction cup enhance the contact between the lower outer wall of the lower seat and the mounting surface, ensuring a tight fit after installation and preventing gaps caused by incomplete fixation. During the overall vibration of the motor, high-frequency contact and collision between the outer wall of the device and the mounting surface reduces vibration noise and improves vibration performance.

[0015] 2. This invention, through the setting of a limiting rod, screw head, threaded groove, pressure plate, and gasket, allows the device to be placed on a designated mounting surface. The bottom end of the limiting rod is inserted into the mounting threaded hole, and the screw head is rotated with a screwdriver to screw the threaded groove at the bottom of the limiting rod into the mounting hole. During this process, the pressure plate descends and applies pressure to the bonding seat. With the assistance of an air extraction operation, the bonding seat descends until it is in complete contact with the inner wall of the lower seat. The rubber gasket protects the internal components of the device, preventing damage or deformation caused by the contact and compression between the bonding seat and the outer wall of the lower seat.

[0016] 3. The present invention, through the setting of permanent magnet, auxiliary seat, wheel block, auxiliary roller, side plate and limiting auxiliary rail, when energized, the permanent magnet is subjected to the magnetic field force and moves laterally, and the auxiliary roller rolls within the limiting auxiliary rail; the auxiliary roller and limiting auxiliary rail can reduce the contact effect between the permanent magnet and the two side plates during the movement, thereby further reducing the friction between the two, improving the movement effect of the permanent magnet and enhancing its sensitivity.

[0017] 4. This invention, through the arrangement of clamping blocks, push seats, push rods, pressure seats, intermediate partition rings, return springs, stop seats, and limiting springs, ensures that when the permanent magnet moves laterally, the push seat drives the push rod and pressure seat to move towards the stop seat. The return spring undergoes elastic deformation, and simultaneously, the stop seat moves under force, causing the limiting spring to elastically deform. The two springs, after deformation, provide opposing forces, causing the permanent magnet to move in the opposite direction again. This process repeats, resulting in the permanent magnet performing high-frequency reciprocating motion within the device, causing the device to vibrate. By utilizing the simultaneous cooperation of the return spring and the limiting spring, which provide opposing forces after elastic deformation to drive the permanent magnet to move in the opposite direction, the high-frequency reciprocating motion of the permanent magnet within the device is ensured, achieving the vibration effect.

[0018] 5. The present invention uses an insulating plate and a coil. The insulating plate can maintain the magnetic field inside the device while providing insulation, thereby improving the magnetic induction effect of the permanent magnet. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] A highly sensitive, high-vibration-sensitivity flat vibration motor, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a lower seat 1 and an upper cover 2. The lower seat 1 is located below the upper cover 2 and is connected to the upper cover 2 by bolts. The lower seat 1 and the upper cover 2 have two symmetrical grooves inside. The inner walls of the two sides of the grooves are slidably connected to a fitting seat 3. Multiple suction cups 4 are provided below the fitting seat 3. A rectangular groove is provided on the upper outer wall of the fitting seat 3. An airflow control valve 5 is connected to the inner wall of the rectangular groove by bolts. The multiple suction cups 4 are connected to the airflow control valve 5 on the same side by pipes. An air supply pipe 6 is connected to the upper port of the airflow control valve 5 by bolts. The air supply pipe 6 is slidably connected to the inner wall of the upper cover 2. The upper cover 2 has two symmetrical circular grooves located in the middle of the upper cover 2. The inner walls of the two circular grooves are connected to air nozzles 7 by bolts. The air nozzles 7 are located above the air supply pipes 6.

[0028] Furthermore, such as Figure 2 As shown, two symmetrical limiting rods 8 are provided on both sides of the air nozzle 7. The limiting rods 8 are slidably connected to the inner walls of the lower seat 1 and the upper cover 2. The top of the limiting rod 8 is connected to a screw head 9 by bolts. The screw head 9 has a plum blossom groove. The lower outer wall of the limiting rod 8 has a threaded groove 10. The outer wall of the limiting rod 8 is connected to a pressure plate 11 by bolts. The pressure plate 11 has an isosceles trapezoidal cross-section. The pressure plate 11 is located between the upper cover 2 and the fitting seat 3. A gasket 12 is sleeved on the outside of the limiting rod 8. The gasket 12 is made of rubber. The gasket 12 is located between the lower seat 1 and the fitting seat 3. The gasket 12 is bonded to the bottom inner wall of the lower seat 1. The rubber gasket 12 can protect the internal components of the device and prevent damage and deformation caused by the contact and squeezing of the fitting seat 3 and the outer wall of the lower seat 1.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, a permanent magnet 13 is installed inside the lower seat 1 and the upper cover 2. The permanent magnet 13 is rectangular in shape and is located between two mating seats 3. Rectangular grooves are formed on both outer walls of the permanent magnet 13. An auxiliary seat 14 is bolted to the inner wall of the rectangular groove. Multiple equidistant wheel blocks 15 are bolted to one outer wall of the auxiliary seat 14. Each wheel block 15 has a groove. An auxiliary roller 16 is rotatably connected between the inner walls of the grooves via bearings. Side plates 17 are provided on both sides of the permanent magnet 13. One outer wall of the side plate 17 is connected to the inner walls of the lower seat 1 and the upper cover 2 by bolts, and the other outer wall of the side plate 17 is provided with a limiting auxiliary rail 18. The auxiliary roller 16 is located inside the limiting auxiliary rail 18. The auxiliary roller 16 is in rolling connection with the inner wall of the limiting auxiliary rail 18. The auxiliary roller 16 and the limiting auxiliary rail 18 can reduce the contact effect between the permanent magnet 13 and the two side plates 17 during the movement, thereby further reducing the friction between them, improving the movement effect of the permanent magnet 13, and enhancing its sensitivity.

[0030] Furthermore, such as Figure 4 and Figure 5 As shown, both ends of the permanent magnet 13 are bolted to clamping blocks 19. Two symmetrical push seats 20 are bolted to one side of each clamping block 19. A push rod 21 is bolted to one side of each push seat 20, and a pressure seat 22 is bolted to the other end of each push rod 21. The pressure seat 22 is slidably connected to the inner walls of the lower seat 1 and the upper cover 2. A central partition ring 23 is bolted to the outside of the push rod 21, located between the push seat 20 and the pressure seat 22. A return spring 24 is sleeved on the outside of each push rod 21, with both ends of the return spring 24 connected to one side of the central partition ring 23 and the pressure seat 22. The lower seat 1 is bolted to one side of the inner wall of the upper cover 2; the outer wall of the pressure seat 22 is bolted to a stop 25, the outer wall of the stop 25 is slidably connected to the inner wall of the lower seat 1 and the upper cover 2, and the other side of the outer wall of the stop 25 is bolted to a limit spring 26, the other end of the limit spring 26 is bolted to the inner wall of the lower seat 1 and the upper cover 2. By using the simultaneous cooperation of the return spring 24 and the limit spring 26, after elastic deformation, a reverse force is provided to drive the permanent magnet 13 to move in the opposite direction, thereby ensuring the high-frequency reciprocating motion of the permanent magnet 13 in the device and realizing the vibration effect.

[0031] Furthermore, such as Figure 1 and Figure 6 As shown, rectangular grooves are provided on the inner walls of both the lower seat 1 and the upper cover 2. The two rectangular grooves are symmetrically distributed on the upper and lower sides of the permanent magnet 13. The inner walls of the two rectangular grooves are connected to insulating plates 27 by bolts. The outer wall of the insulating plate 27 near the permanent magnet 13 is connected to multiple coils 28 by bolts. The multiple coils 28 are equidistantly distributed. The insulating plate 27 can maintain the magnetic field inside the device while insulating, thereby improving the magnetic induction effect of the permanent magnet 13.

[0032] Working principle: After the device is placed on the designated mounting surface, the bottom end of the limiting rod 8 is inserted into the mounting threaded hole. The screw head 9 is turned with a screwdriver to screw the threaded groove 10 at the bottom of the limiting rod 8 into the mounting hole. During this process, the pressure plate 11 will descend and apply pressure to the bonding seat 3. After the lower seat 1 contacts the mounting surface, it is squeezed and bonded. The external air suction pipe is inserted into the air nozzle 7 to perform air suction. The suction cup 4 is bonded to the mounting surface more deeply and the air accumulated in the suction cup 4 is extracted. The bonding seat 3 descends until it is in complete contact with the inner wall of the lower seat 1.

[0033] After being powered on, the permanent magnet 13 moves laterally under the influence of the magnetic field. The auxiliary roller 16 rolls within the limiting auxiliary rail 18. When the permanent magnet 13 moves laterally, the push seat 20 drives the push rod 21 and the pressure seat 22 to move towards the stop seat 25. The reset spring 24 undergoes elastic deformation. At the same time, the stop seat 25 moves after being subjected to force, and the limiting spring 26 undergoes elastic deformation. After the two springs deform, they provide opposite forces, and the permanent magnet 13 moves in the opposite direction again under the force. This process is repeated, and the permanent magnet 13 performs high-frequency reciprocating motion inside the device, causing the device to vibrate.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
