Description
Technical Field
[0001] The utility model belongs to the field of rolling door motors, and more specifically, relates to a vibration-damping and noise-reducing device for rolling door motors. Background Art
[0002] The rolling door motor is a key component that drives the rolling door to open and close. The motor transmits power to the roller of the rolling door through the drive transmission device. In order to prevent the rolling door from exceeding the predetermined position during the lifting process, it is equipped with a limit switch or sensor for limit control.
[0003] However, the inertial vibration generated by the rolling door motor during operation will cause noise in the installation parts it contacts, and the chain connected to the motor will also shake, which can easily cause problems such as falling off. Utility Model Content
[0004] In order to solve the above technical problems, the purpose and effect of the utility model of a vibration reduction and silencer device for a rolling door motor are achieved by the following specific technical means:
[0005] Its structure includes a connecting belt, a turntable, a mounting plate, a limiting seat, a fixed grid, a shock-absorbing frame, and a motor. The connecting belt connects the motor and the turntable. The limiting seat is fixed to the surface of the mounting plate to support the connecting belt. The shock-absorbing frame is installed at the bottom of the motor. The fixed grid is welded to the outer surface of the mounting plate.
[0006] The shock-absorbing frame passes through the inside of the mounting plate to support the motor. The end of the shock-absorbing frame away from the motor is fixed on the inner side of the fixed grid. The limiting seat is provided with two to support both sides of the connecting belt. There are four shock-absorbing frames in total, all of which are supported at the lower end of the motor. The shock-absorbing frame evenly supports the bottom of the motor and plays a role in force buffering.
[0007] As a further improvement of the present invention, the shock absorber frame includes a connecting body, a main rod, a fixing ring, a support rod, a support ring, and an airbag. The connecting body is sleeved on the upper end of the main rod, the fixing ring is fixed to the outer ring surface of the main rod, the support ring is fixed to the surface of the mounting plate, the support rod is supported between the fixing ring and the support ring, the airbag is located at the bottom of the main rod, and the support rod is made of a spring plate material, which can play the role of bending buffer support when subjected to force.
[0008] As a further improvement of the present invention, the airbag includes a bag core, a pressure block, an elastic layer, and a spring body. The bag core and the elastic layer are an integrated structure. The spring body is supported at the inner middle end of the elastic layer. The pressure block is fixed at the upper and lower ends of the elastic layer. The pressure block is connected to the main rod. The spring body supports external forces through its own elasticity.
[0009] As a further improvement of the present invention, the limiting seat includes a fixed seat, a limiting plate, a side plate, and a protective layer. The limiting plate and the side plate are an integrated structure. The protective layer is attached to the surface of the side plate. The limiting plate is fixed to the upper end of the fixed seat. The side plate and the limiting plate form a concave structure to limit the connecting belt.
[0010] As a further improvement of the present invention, the connecting body is fixed to the bottom of the motor, the inner ring of the support ring has a certain spatial distance from the main rod, a group of six support rods are evenly distributed in a circle, and the fixed ring moves with the main rod.
[0011] As a further improvement of the present invention, the fixing ring, the support rod and the support ring form a trapezoidal structure. The support rod can rebound and buffer in time when bent under force. The two groups of support rods are one structure and are mirrored, with a total of four groups, which enhances the supporting effect.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The vibration force generated by the motor's own inertia during operation will be supported and transmitted through the main rod of the shock absorber frame. The support rod supports the fixed ring and the support ring to play a buffering support role. The support ring is fixed to the surface of the mounting plate, giving the support rod a fixed support force. When the support rod is subjected to force, it is properly buffered by its own elasticity, and the fixed ring and the main rod are promptly bounced back to their original position to maintain the support role. It can consolidate the support role when the motor is stationary. When the motor generates inertial vibration, the support part will form an elastic buffering role to reduce vibration so that the motor will not directly contact the mounting plate to generate noise.
[0014] 2. When the motor drives the turntable to rotate through the connecting belt, the vibration generated by the motor during operation will affect the connecting belt. One end of the connecting belt is fixed to the turntable in a stable state, and the other end is in contact with the motor and is prone to falling off. When the connecting belt shakes with the motor, it will be limited by the side plate and the limit plate to prevent the connecting belt from shaking excessively, generating inertia and falling off the motor.

[0022] As attached Figure 1 To the attached Figure 5 As shown:
[0023] The utility model provides a shock-absorbing and silencing device for a rolling door motor, the structure of which includes a connecting belt 1, a turntable 2, a mounting plate 3, a limiting seat 4, a fixed grid 5, a shock-absorbing frame 6, and a motor 7. The connecting belt 1 is connected between the motor 7 and the turntable 2, the limiting seat 4 is fixed to the surface of the mounting plate 3 to support the connecting belt 1, the shock-absorbing frame 6 is installed at the bottom of the motor 7, and the fixed grid 5 is welded to the outer surface of the mounting plate 3;
[0024] The shock-absorbing frame 6 passes through the inside of the mounting plate 3 to support the motor 7. The end of the shock-absorbing frame 6 away from the motor 7 is fixed to the inside of the fixed grid 5. The limiting seat 4 is provided with two to support both sides of the connecting belt 1. There are four shock-absorbing frames 6 in total, all of which are supported on the lower end of the motor 7. The shock-absorbing frame 6 evenly supports the bottom of the motor 7 and plays a role in force buffering. The limiting seat 4 plays a role in maximum limiting when preventing the connecting belt 1 from shaking.
[0025] Among them, the shock absorber frame 6 includes a connecting body 61, a main rod 62, a fixing ring 63, a support rod 64, a support ring 65, and an airbag 66. The connecting body 61 is sleeved on the upper end of the main rod 62, the fixing ring 63 is fixed to the outer ring surface of the main rod 62, the support ring 65 is fixed to the surface of the mounting plate 3, the support rod 64 is supported between the fixing ring 63 and the support ring 65, and the airbag 66 is located at the bottom of the main rod 62. The support rod 64 is made of a spring plate material and can play a role of bending buffer support when subjected to force. The airbag 66 supports the main rod 62 to assist it in buffering the force.
[0026] Among them, the airbag 66 includes a bag core 51, a pressure block 52, an elastic layer 53, and a spring body 54. The bag core 51 and the elastic layer 53 are an integrated structure. The spring body 54 is supported on the inner middle end of the elastic layer 53. The pressure block 52 is fixed on the upper and lower ends of the elastic layer 53. The pressure block 52 is connected to the main rod 62. The spring body 54 supports external forces through its own elasticity. The elastic layer 53 is a variable outer layer, which assists in deformation when subjected to force and plays a role in buffering the return.
[0027] Among them, the limiting seat 4 includes a fixed seat 41, a limiting plate 42, a side plate 43, and a protective layer 44. The limiting plate 42 and the side plate 43 are an integrated structure. The protective layer 44 is attached to the surface of the side plate 43. The limiting plate 42 is fixed to the upper end of the fixed seat 41. The side plate 43 and the limiting plate 42 form a concave structure to limit the connecting belt 1. The protective layer 44 plays a certain protective role during the movement of the connecting belt 1.
[0028] Among them, the connecting body 61 is fixed to the bottom of the motor 7, the inner circle of the support ring 65 has a certain spatial distance from the main rod 62, and a group of six support rods 64 are evenly distributed in a circle. The fixed ring 63 moves together with the main rod 62, and the support ring 65 is in a fixed state to support its support rod 64 so that it has a fixed force point.
[0029] Among them, the fixing ring 63 and the support rod 64 and the support ring 65 form a trapezoidal structure. The support rod 64 can rebound and buffer in time when it is bent under force. The two groups of support rods 64 are one structure and are mirrored in a total of four groups to enhance the supporting effect. The all-round support of the shock absorber frame 6 can provide sufficient supporting force for the main rod 62 when it is static.
[0030] The specific usage and function of this embodiment are as follows:
[0031] In the present invention, the motor 7 starts to run and drives the turntable 2 to rotate together through the connecting belt 1. The vibration force generated by the inertia of the motor 7 during operation will be supported and transmitted through the main rod 62 of the shock-absorbing frame 6, and the fixing ring 63 fixed to the surface of the main rod 62 will vibrate along with the main rod 62. Its support rod 64 is supported between the fixing ring 63 and the support ring 65 to play the role of buffer support. The support ring 65 is fixed to the surface of the mounting plate 3 to give the support rod 64 a fixed support force. The support ring 65 has no direct contact with the main rod 62, so that the main rod 62 is supported and relieved by the support rod 64 when vibrating. After the support rod 64 is properly buffered by its own elasticity when subjected to force, its fixing ring 63 and the main rod 62 are timely connected. It rebounds to its original position and maintains its supporting effect. When the main rod 62 is subjected to force, it is not only supported by the support rod 64, but also by the air bag 66 at the bottom. When the main rod 62 is subjected to force to press the pressure block 52, the elastic body 54 inside it will be deformed to squeeze the bag core 51, and the shape of its elastic layer 53 will change to provide buffering. After buffering, the auxiliary air bag 66 can rebound in time to support the main rod 62 back to its position. When the motor 7 generates inertial vibration, the connected connecting belt 1 will shake, and the side plate 43 supported by the fixed seat 41 and the limit plate 42 limit the connecting belt 1. The connecting belt 1 is protected by the protective layer 44 on the side plate 43 during movement to prevent one end of the connecting belt 1 from being fixed and the other end from moving, thereby causing it to fall off.
[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
