Description

Technical Field

[0001] This utility model belongs to the field of vibration motor technology, specifically referring to a low-temperature vibration motor. Background Technology

[0002] A vibratory motor has an adjustable eccentric wheel installed at each end of the rotor shaft. It uses the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain the excitation force. Vibratory motors have a wide vibration frequency range, and traditional vibratory motors can basically meet people's needs.

[0003] However, existing vibration motors generate more heat as the frequency increases, resulting in high internal heat, which affects service life and can easily lead to circuit burnout. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes a low-temperature vibration motor, which effectively solves the problem that the heat generated by the vibration motor increases with the increase of frequency, resulting in high internal heat of the vibration motor, affecting its service life and making it prone to circuit burnout.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a low-temperature vibration motor, including a fixed base and a low-temperature vibration structure. The low-temperature vibration structure is disposed on the fixed base and includes a motor housing, an air inlet, a clamp, a permanent magnet, a rotating shaft, a coil, a connecting seat, a side cover, a vent, a protective shell, a first fixing bolt, an exhaust port, an exhaust fan, a round seat, an eccentric block, and a second fixing bolt. The motor housing is welded to the top of the fixed base. The air inlet penetrates the motor housing. The clamp is fixedly disposed inside the motor housing. The permanent magnet is fixedly disposed on the clamp. The rotating shaft passes through the rotation center of the motor housing and is rotatably disposed thereon. The coil is wound around the outside of the rotating shaft. The connecting seat is fixed at both ends of the motor housing. The side cover is detached and located outside the connecting seat, and the side cover rotates through the rotating shaft. The vent hole is located through the side cover. The protective shell is detached and located outside the side cover, and the rear ends of the two sets of protective shells cover the left and right ends of the rotating shaft respectively. One fixing bolt is fixed through the connecting seat, the side cover, and the protective shell. The exhaust hole is located through one end of the protective shell. The exhaust fan is fixed at the left and right ends of the rotating shaft. The round seat is sleeved on the rotating shaft. The eccentric block is located outside the round seat. Two fixing bolts are threaded on the round seat and press the rotating shaft to fix it.

[0006] Preferably, the eccentric block is configured in a fan-shaped structure.

[0007] To achieve better cooling, several sets of air inlets are provided on the outside of the motor housing.

[0008] To achieve rotation more quickly, three sets of clamps are arranged at 120-degree intervals inside the motor housing.

[0009] Furthermore, the exhaust fans are arranged in two sets on the left and right sides, and the blades of the exhaust fans are tilted in opposite directions.

[0010] To achieve the effect of low temperature, the air inlet penetrates the motor housing and forms a circulation channel with the vent and exhaust ports.

[0011] The beneficial effects of this utility model using the above structure are as follows: The low-temperature vibration motor proposed in this solution discharges internal heat with airflow through exhaust fans at both ends. At this time, external cold airflow enters the motor housing through the air inlet, absorbing and carrying away the heat generated by the coil, thereby keeping the motor in a low-temperature state.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model proposes a low-temperature vibration motor, including a fixed base 1 and a low-temperature vibration structure 2. The low-temperature vibration structure 2 is mounted on the fixed base 1 and includes a motor housing 3, an air inlet 4, a clamp 5, a permanent magnet 6, a rotating shaft 7, a coil 8, a connecting seat 9, a side cover 10, a vent 11, a protective shell 12, a first fixing bolt 13, an exhaust port 14, an exhaust fan 15, a round seat 16, an eccentric block 17, and a second fixing bolt 18. The motor housing 3 is welded to the top of the fixed base 1. The air inlet 4 penetrates the motor housing 3 and is arranged in several groups on the outside of the motor housing 3. The clamp 5 is fixed inside the motor housing 3 and is arranged in three groups at 120-degree intervals inside the motor housing 3. The permanent magnet 6 is fixed on the clamp 5. The rotating shaft 7 penetrates the center of rotation of the motor housing 3 and is rotatably mounted. The coil 8 is wound around the outside of the rotating shaft 7. The connecting seat 9 is fixed to the motor housing 3. At both ends of the motor housing 3, the side cover 10 is detached and installed outside the connecting seat 9, and the side cover 10 is rotatably installed through the rotating shaft 7. The vent hole 11 is installed through the side cover 10. The protective shell 12 is detached and installed outside the side cover 10, and the rear ends of the two sets of protective shells 12 respectively cover the left and right ends of the rotating shaft 7. The fixing bolt 13 is fixed through the connecting seat 9, the side cover 10 and the protective shell 12. The exhaust hole 14 is installed through one end of the protective shell 12. The air inlet 4 is installed through the motor housing 3 and forms a circulation channel with the vent hole 11 and the exhaust hole 14. The exhaust fan 15 is fixed at the left and right ends of the rotating shaft 7. Two sets of exhaust fans 15 are arranged on the left and right sides, and the blades of the exhaust fan 15 are tilted in opposite directions. The round seat 16 is sleeved on the rotating shaft 7. The eccentric block 17 is installed outside the round seat 16. The eccentric block 17 is arranged in a fan shape. The fixing bolt 18 is threaded on the round seat 16 and presses the rotating shaft 7 to fix it.

[0020] In practical use, when the power is turned on, the current flows through the coil 8. The coil 8 rotates under the action of the permanent magnet 6. As the current increases, the rotation frequency increases, and the heat generated also increases. At this time, the exhaust fan 15 fixed on the rotating shaft 7 rotates to expel air outward. The airflow drives the heat inside the motor housing 3 to be discharged through the exhaust port 14. At this time, a negative pressure is formed inside the motor housing 3. At this time, external air enters the motor housing 3 through the air inlet 4, thereby continuing to carry away heat, thus keeping the vibration motor at a low temperature and improving its service life. The above is the entire process of using the low-temperature vibration motor.
