Description
Technical Field
[0001] The utility model relates to the field of generators, in particular to a shock-absorbing base of a silent unit. Background Art
[0002] The motor includes a motor base and a motor body mounted on the motor base. During the use of the motor, the running motor has a certain vibration. Under this vibration, the motor has a large hard impact force, the mounting bolts are easy to loosen, the motor has poor running stability, and is easy to be damaged. In addition, under strong vibration, it is usually accompanied by huge noise, which is extremely unfavorable for the setting of the motor, especially the setting of a silent unit with high noise requirements. The formation of noise is determined by the sound source and the propagation path. In the existing silent units, most of them add a silent box to the motor to block the external transmission of noise on the sound propagation path, thereby achieving the effect of reducing noise, but the noise problem is not fundamentally solved at the sound source. Although a few silent units have added a shock absorbing mechanism on the motor base, and the shock absorbing effect of the shock absorbing mechanism is used to minimize the generation of the sound source, the shock absorbing mechanism on the existing motor base is mostly a rubber pad or spring structure. Under the rubber pad or spring structure, the rubber pad and the spring are easy to be damaged, and the elasticity of the rubber pad and the spring at each position is easy to be unbalanced. After the imbalance, not only the shock absorbing effect of the shock absorbing mechanism is greatly reduced, but on the contrary, due to the different supporting forces at each position, the coaxiality of the motor is also affected. Utility Model Content
[0003] The utility model aims to provide a shock-absorbing machine base for a silent machine set.
[0004] The technical solution to achieve the purpose of the utility model is: a shock-absorbing base of a silent unit, including a fixed base and a movable base, the fixed base includes a bottom plate and a wall body fixedly installed on the bottom plate, two horizontally arranged sliders are arranged in the fixed base, a linear track is arranged on the bottom plate, the bottoms of the two sliders are slidably or rollingly installed on the linear track of the bottom plate, a first shock-absorbing mechanism is arranged between the two sliders and the adjacent wall body, the first shock-absorbing mechanism includes two relatively arranged arc-shaped steel plates, one end of the arc-shaped steel plate is hinged to the adjacent wall body, and the The other end of the arc-shaped steel plate is hinged to the adjacent slider, and the upper surfaces of the two sliders each have an inclined surface, and the two inclined surfaces are arranged opposite to each other in an inverted eight-shaped shape, and the cross-section of the inclined surface is a concave arc; the movable seat is located above the fixed seat, and a second shock-absorbing mechanism is provided on the bottom surface of the movable seat, and the second shock-absorbing mechanism includes an arched steel plate and two groups of rollers, the top of the arched steel plate is fixedly installed on the bottom surface of the movable seat, and the two groups of rollers are rotatably installed on the two ends of the arched steel plate, and the two groups of rollers are respectively located on the two inclined surfaces.
[0005] Furthermore, the first shock absorbing mechanism further includes a first damper, one end of which is connected to the adjacent wall body, and the other end of which is connected to the adjacent slider. The first damper has a shock absorbing effect. Specifically, the first damper pulls the slider, and the first damper limits the movement of the slider through its own deformation, thereby shock absorbing the movable seat. Under the dual action of the first damper and the arc-shaped steel plate, the shock absorbing effect of the first shock absorbing mechanism is better.
[0006] Furthermore, the first damper is any one of a spring damper, a cylinder damper, and a hydraulic damper.
[0007] Furthermore, several second dampers are evenly distributed between the movable seat and the wall body. The second dampers are vertically arranged, one end of the second damper is connected to the wall body, and the other end of the second damper is connected to the bottom surface of the movable seat. The second damper is used to reduce the shock of the movable seat. When the second damper plays a shock absorbing role, specifically, the second damper pulls the movable seat, and the second damper reduces the vibration of the movable seat through its own deformation. The second damper can not only buffer the downward movement of the movable seat, but also restrain the upward movement of the movable seat. The second damper directly reduces the vibration of the movable seat. Since the second damper can restrain the upward and downward movement of the movable seat, the second damper is involved in the entire process of the movable seat, and the second damper has an obvious shock absorbing effect.
[0008] Furthermore, the second damper is any one of a spring damper, a cylinder damper, and a hydraulic damper.
[0009] Furthermore, the movable seat is a cover structure, and the movable seat has a downward cover edge, and the cover edge is located outside the wall. The setting of the cover edge can further limit the horizontal position of the fixed seat and the movable seat, and can also encapsulate the fixed seat to prevent dust and debris from entering the fixed seat and affecting the shock absorption effect.
[0010] The shock-absorbing base of the silent unit of the utility model, on the one hand, by fixing the arched steel plate on the bottom surface of the movable seat, the arched steel plate of the second shock-absorbing mechanism directly absorbs the vibration of the movable seat; on the other hand, the coordinated arrangement of the arched steel plate and the two sliding blocks allows the force of the arched steel plate on the two sliding blocks to be partially converted into horizontal movement of the sliding blocks, and then the sliding blocks are buffered by the first shock-absorbing mechanism to achieve shock absorption of the movable seat. During the shock absorption process of the first shock-absorbing mechanism, the two ends of the arched steel plate are pressed against the two sliding blocks through rollers. In addition to the horizontal force on the two sliding blocks, the arched steel plate also has a vertical force. Conversely, the two sliding blocks also have a vertical force on the second shock-absorbing mechanism. The vertical force supports the second shock-absorbing mechanism and the movable seat thereon, so that the movable seat has sufficient supporting force.
[0011] The shock-absorbing base of the silent unit of the utility model, the dual setting of the second shock-absorbing mechanism and the first shock-absorbing mechanism, provides a good shock-absorbing effect for the movable seat and the motor thereon; and in the shock-absorbing structure of the first shock-absorbing mechanism, the arched steel plate and the two sliding blocks also provide reliable support for the movable seat.
[0012] In addition, in the shock-absorbing base of the silent unit of the utility model, no rubber pads or spring structures are used in the second shock-absorbing mechanism and the first shock-absorbing mechanism. The arched steel plate of the second shock-absorbing mechanism and the arc-shaped steel plate of the first shock-absorbing mechanism have high structural strength, strong deformation resistance and deformation recovery capabilities, are not easy to damage, and have a long service life. In particular, the arched steel plate not only provides reliable support for the movable seat, but also has a good shock-absorbing effect, which can greatly improve the silent effect of the silent unit.

[0015] The following is a detailed description of the preferred implementation of the shock-absorbing base of the utility model silent unit in conjunction with the accompanying drawings:
[0016] The technical solution to achieve the purpose of the utility model is: a shock-absorbing machine base of a silent unit, including a fixed base 1 and a movable base 2, the fixed base 1 including a bottom plate 11 and a wall body 12 fixedly mounted on the bottom plate 11, two horizontally arranged sliders 3 are arranged in the fixed base 1, a linear track 111 is arranged on the bottom plate 11, the bottoms of the two sliders 3 are slidably or rollingly mounted on the linear track 111 of the bottom plate 11, a first shock-absorbing mechanism 4 is arranged between the two sliders 3 and the adjacent wall body 12, the first shock-absorbing mechanism 4 includes two oppositely arranged arc-shaped steel plates 41, one end of the arc-shaped steel plate 41 is hinged to the adjacent wall body 12, The other end of the arc-shaped steel plate 41 is hinged to the adjacent slider 3, and the upper surfaces of the two sliders 3 each have an inclined surface 31, and the two inclined surfaces 31 are arranged opposite to each other in an inverted eight-shaped shape, and the cross-section of the inclined surface 31 is a concave arc; the movable seat 2 is located above the fixed seat 1, and a second shock-absorbing mechanism 5 is provided on the bottom surface of the movable seat 2, and the second shock-absorbing mechanism 5 includes an arched steel plate 51 and two groups of rollers 52, the top of the arched steel plate 51 is fixedly installed on the bottom surface of the movable seat 2, and the two groups of rollers 52 are rotatably installed at the two ends of the arched steel plate 51, and the two groups of rollers 52 are respectively located on the two inclined surfaces 31.
[0017] In the shock-absorbing base of the silent unit of the utility model, in the second shock-absorbing mechanism 5, the arched steel plate 51 is used to absorb the up and down vibration of the movable seat 2, and also to transition the force of the movable seat 2 so that it is transmitted to the slider 3; the roller 52 plays a rolling role to reduce the friction between the second shock-absorbing mechanism 5 and the slider 3. The bottom of the slider 3 is installed on the linear track 111, and can move linearly along the linear track 111; the slider 3 is used to carry the motor on the one hand, and to provide power for the linear movement of the slider 3 on the other hand. The first shock-absorbing mechanism 4 is horizontally arranged with the two sliders 3, and the first shock-absorbing mechanism 4 is located on the outside of the two sliders 3, and is used to buffer the horizontal linear movement of the slider 3.
[0018] The shock-absorbing machine base of the silent unit of the utility model, when working, the motor is installed on the movable base 2, and the movable base 2 vibrates up and down with the vibration of the motor. During the up and down vibration of the movable base 2, the second shock-absorbing mechanism 5 and the first shock-absorbing mechanism 4 work together to buffer and dampen the movable base 2.
[0019] The shock-absorbing base of the silent unit of the utility model, when the second shock-absorbing mechanism 5 plays a shock-absorbing role, specifically, as the movable seat 2 vibrates up and down, during the downward movement of the movable seat 2, the movable seat 2 generates a force on the arched steel plate 51 of the second shock-absorbing mechanism 5, and a part of the force is converted into the deformation of the arched steel plate 51, thereby realizing the buffering and shock-absorbing effect of the second shock-absorbing mechanism 5; during the upward movement of the movable seat 2, the arched steel plate 51 of the second shock-absorbing mechanism 5 recovers its deformation.
[0020] In the damping base of the silent unit of the utility model, during the deformation of the arched steel plate 51, the two groups of rollers 52 of the second damping mechanism 5 roll along the two inclined surfaces 31, and the friction between the rollers 52 and the inclined surfaces 31 is small. In addition, the cross section of the inclined surface 31 is an inwardly concave arc, and the arc structure can limit the rollers 52 to prevent the rollers 52 from rolling out of the two inclined surfaces 31.
[0021] The shock absorbing base of the silent unit of the utility model, when the first shock absorbing mechanism 4 plays a shock absorbing role, specifically, during the downward movement of the movable seat 2, after the movable seat 2 generates a force on the arched steel plate 51, a part of it is converted into the deformation of the arched steel plate 51 of the second shock absorbing mechanism 5, and the other part is tilted downwardly transferred to the slider 3. After the force transferred to the slider 3 is decomposed, a part of it is a vertical force, which directly acts on the slider 3 and is supported by the slider 3, and the other part is a horizontal force. The horizontal force acts on the two sliders 3, so that the two sliders 3 move away from each other along the linear track 111, squeezing the first shock absorbing mechanism 4, and the arc steel plate 41 of the first shock absorbing mechanism 4 eliminates the force of the slider 3 on it through its own deformation, thereby achieving the effect of buffering and shock absorbing; during the upward movement of the movable seat 2, the arc steel plate 41 of the first shock absorbing mechanism 4 recovers its deformation, and the arc steel plate 41 of the first shock absorbing mechanism 4 that recovers its deformation presses the slider 3, so that the two sliders 3 are close to each other. That is to say, the cooperation between the arched steel plate 51 and the two sliders 3 converts the force transmitted from the movable seat 2 to the slider 3 through the arched steel plate 51 into horizontal movement of the slider 3, and then the first shock absorbing mechanism 4 buffers the slider 3, thereby achieving the effect of shock absorbing the movable seat 2.
[0022] The shock-absorbing base of the silent unit of the utility model, on the one hand, by fixing the arched steel plate 51 on the bottom surface of the movable seat 2, the arched steel plate 51 of the second shock-absorbing mechanism 5 directly absorbs the vibration of the movable seat 2; on the other hand, the matching arrangement of the arched steel plate 51 and the two sliding blocks 3 enables the force of the arched steel plate 51 on the two sliding blocks 3 to be partially converted into the horizontal movement of the sliding blocks 3, and then the sliding blocks 3 are buffered by the first shock-absorbing mechanism 4 to achieve the shock absorption of the movable seat 2. During the shock absorption process of the first shock-absorbing mechanism 4, the two ends of the arched steel plate 51 are pressed on the two sliding blocks 3 through rollers 52. In addition to the horizontal force on the two sliding blocks 3, the arched steel plate 51 also has a vertical force. Conversely, that is, the two sliding blocks 3 also have a vertical force on the second shock-absorbing mechanism 5. The vertical force supports the second shock-absorbing mechanism 5 and the movable seat 2 thereon, so that the movable seat 2 has sufficient supporting force.
[0023] The shock-absorbing base of the silent unit of the utility model, the dual setting of the second shock-absorbing mechanism 5 and the first shock-absorbing mechanism 4, provides a good shock-absorbing effect for the movable seat 2 and the motor thereon; and in the shock-absorbing structure of the first shock-absorbing mechanism 4, the arched steel plate 51 and the two sliding blocks 3 also provide reliable support for the movable seat 2.
[0024] In addition, in the shock-absorbing base of the silent unit of the utility model, no rubber pads or spring structures are used in the second shock-absorbing mechanism 5 and the first shock-absorbing mechanism 4. The arched steel plate 51 of the second shock-absorbing mechanism 5 and the arc-shaped steel plate 41 of the first shock-absorbing mechanism 4 have high structural strength, strong deformation resistance and deformation recovery capabilities, are not easy to damage, and have a long service life. In particular, the arched steel plate 51 not only provides reliable support for the movable seat 2, but also has a good shock-absorbing effect.
[0025] In the shock-absorbing base of the silent unit of the utility model, the slider 3 is installed on the fixed bottom plate 11, and the operation of the slider 3 is stable; and the overall strength of the arched steel plate 51 of the second shock-absorbing mechanism 5 is large, and when the slider 3 and the second shock-absorbing mechanism 5 work together, the movement is more stable.
[0026] The shock-absorbing base of the silent unit of the utility model, preferably, the first shock-absorbing mechanism 4 also includes a first damper 42, one end of the first damper 42 is connected to the adjacent wall 12, and the other end of the first damper 42 is connected to the adjacent slider 3. The first damper 42 is parallel to the linear track 111, and the first damper 42 plays a shock-absorbing role. Specifically, the first damper 42 pulls the slider 3, and the first damper 42 limits the movement of the slider 3 through its own deformation, thereby shock-absorbing the movable seat 2. Under the dual action of the first damper 42 and the arc-shaped steel plate 41, the shock-absorbing effect of the first shock-absorbing mechanism 4 is better.
[0027] In the shock-absorbing base of the silent unit of the utility model, preferably, the first damper 42 is any one of a spring damper, a cylinder damper and a hydraulic damper.
[0028] The damping machine base of the silent machine set of the utility model is preferably evenly distributed with a plurality of second dampers 6 between the movable seat 2 and the wall 12. The second dampers 6 are vertically arranged, one end of the second damper 6 is connected to the wall 12, and the other end of the second damper 6 is connected to the bottom surface of the movable seat 2. The second damper 6 is used to dampen the vibration of the movable seat 2. When the second damper 6 plays a damping role, specifically, the second damper 6 pulls the movable seat 2, and the second damper 6 dampens the vibration of the movable seat 2 through its own deformation. The second damper 6 can not only buffer the downward movement of the movable seat 2, but also restrain the upward movement of the movable seat 2. The second damper 6 directly dampens the vibration of the movable seat 2. Since the second damper 6 can restrain the upward and downward movement of the movable seat 2, the second damper 6 is involved in the entire process of the movable seat 2, and the second damper 6 has an obvious damping effect.
[0029] In the shock absorbing base of the silent unit of the utility model, preferably, the second damper 6 is any one of a spring damper, a cylinder damper and a hydraulic damper.
