Description

Technical Field

Background

A relay is an electronic control device that is commonly used in automatic control circuits. The relay comprises a control system and a controlled system, wherein the control system is used as an input loop, the controlled system is used as an output loop, and actually, a small current is used for controlling a large current to realize the function of 'automatic switching'.

The high-voltage direct-current relay is used as a special relay and mainly applied to electric automobiles to carry out on-off control on charging and discharging of batteries. In the actual use process, the relay is in a state that the contact and the iron core are completely closed before being disconnected, the large spring is compressed to overtravel for providing contact pressure, and the small spring is also compressed for providing contact disconnection force. At this point, both springs are compressed, storing the potential energy of the springs. If the relay coil drive end receives a power-off command, the energy stored by the spring is converted into the kinetic energy of the whole moving assembly, so that the relay contacts are separated, and the whole movement is not terminated until the driving rod assembly impacts the yoke plate. The impact of the drive rod assembly with the yoke plate is very strong due to the high energy, resulting in a very loud relay noise during this process. However, the general automobile needs to consider the driving low-noise experience of passengers, and the sound of the switching action of the relay is required to be small enough, and the noise is lower than 60dB, so as not to bring the noise experience to the user.

Most of relays in the prior art are not provided with noise reduction facilities, or are only provided with soft pads such as rubber at the stop positions of the driving rod assembly, so that the impact of the driving rod assembly on the yoke iron plate is buffered when the driving rod assembly is released, and the noise is reduced. Because the cushion is easy to deform, the noise reduction effect is not obvious, and because the relay is frequently switched on and off, the mechanical life of dozens of thousands of times is needed, the cushion is easy to generate fatigue failure, and foreign matters are generated.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a detailed description thereof will be omitted.

The present embodiment provides a relay, as shown in fig. 1, the relay includes a yoke plate 300, an insulating cover, a movable spring 500, a driving rod assembly 200, a stationary contact terminal 400, and an electromagnet unit 600, where the electromagnet unit 600 includes a coil and an iron core assembly, the iron core assembly includes a movable iron core, and the movable iron core is movably disposed with respect to the coil; the driving lever assembly 200 is inserted through the yoke plate 300 and coupled to the movable iron core configured to drive the movable spring 500 to move toward or away from the stationary contact terminal 400, so that the movable spring 500 is selectively brought into and out of contact with the stationary contact terminal 400.

In the relay provided by the embodiment, the driving rod assembly 200 is inserted into the yoke plate 300, and the movable iron core drives the movable spring 500 to move towards the direction close to or far away from the stationary contact leading-out terminal 400, so that the movable spring 500 is selectively contacted with and separated from the stationary contact leading-out terminal 400, and when the movable spring 500 is contacted with the stationary contact at the bottom of the stationary contact leading-out terminal 400, the load is communicated. If there is a pair of stationary contact terminals 400, the current flows in from one stationary contact terminal 400 and flows out from the other stationary contact terminal 400 after passing through movable spring 500.

Wherein, the insulating cover is arranged in yoke iron plate 300, stationary contact leading-out terminal 400 wears to locate the insulating cover and at least part stretches into in the insulating cover, and movable contact reed 500 sets up in the insulating cover. Set up on yoke iron plate 300 through the insulating boot, in stationary contact terminal 400 wears to locate the insulating boot and at least part stretches into the insulating boot, the insulating boot provides fixed position for stationary contact terminal 400, and the insulating boot provides insulating environment for stationary contact terminal 400, movable contact spring 500 and actuating lever subassembly 200.

If separation between the stationary contact terminal 400 and the movable spring 500 is required, the driving lever assembly 200 drives the movable spring 500 to move in the first direction away from the stationary contact terminal 400, there may be a large impact between the driving lever assembly 200 and the yoke plate 300, resulting in generation of large noise.

To solve this problem, the present embodiment provides a noise reduction shim 100, as shown in fig. 1-2, with the noise reduction shim 100 positioned between the drive rod assembly 200 and the yoke plate 300.

Through being provided with between actuating lever subassembly 200 and yoke board 300 and fall the gasket 100 of making an uproar, fall the gasket 100 of making an uproar and play the isolated effect between actuating lever subassembly 200 and the yoke board 300, actuating lever subassembly 200 does not directly contact with yoke board 300, but falls the gasket 100 direct contact of making an uproar, falls the gasket 100 of making an uproar and play the effect of buffering and making an uproar, realizes the effect that reduces the production of noise and the propagation of suppression noise.

If the noise reduction gasket 100 is made of materials with soft textures such as rubber, the noise reduction and buffering can be realized by utilizing the deformation of the noise reduction gasket, but the relay needs to be frequently switched on and off, the materials with soft textures such as rubber have high fatigue resistance, are easy to lose efficacy, and can generate foreign matters such as fragments, so that the use performance is influenced.

In order to solve the problem, as shown in fig. 3-5, an embodiment of the present invention provides a noise reduction pad 100 including a bearing portion 1, a supporting portion 2 and a flexible deformation portion 3, wherein the bearing portion 1 is disposed in an accommodating groove 302 of a yoke plate 300, the supporting portion 2 is connected to the bearing portion 1, and the supporting portion 2 is located above the bearing portion 1 along a first direction. The driving lever assembly 200 is configured to penetrate the supporting portion 2 along the first direction and selectively abut against the supporting portion 2; the flexible deformation part 3 is arranged between the bearing part 1 and the support part 2 and is used for buffering and reducing noise between the support part 2 and the bearing part 1; wherein the noise reduction gasket 100 is made at least partially of a rigid material.

The noise reduction gasket 100 provided by the embodiment is made of rigid materials at least in part through the noise reduction gasket 100, so that the noise reduction gasket 100 is high in self strength, difficult to deform and good in fatigue resistance, and is difficult to generate foreign matters, and long in service life. The bearing part 1 is arranged in the accommodating groove 302 of the yoke iron plate 300, and the bearing part 1 is equivalent to a lower supporting surface, so that the bearing part 1 plays a role of integral support and provides a supporting position for the noise reduction gasket 100 to be placed on the yoke iron plate 300. The driving rod assembly 200 is configured to penetrate through the supporting portion 2 along the first direction, the supporting portion 2 provides an avoiding space for the movement of the driving rod assembly 200, and the driving rod assembly 200 selectively abuts against the supporting portion 2, so that the supporting portion 2 provides a stressed supporting position for the driving rod assembly 200 relative to an upper supporting surface.

When the existing driving rod assembly 200 is released, the yoke plate 300 is directly impacted, the driving rod assembly 200 is impacted on the supporting portion 2, the bearing portion 1 contacts the yoke plate 300, impact point transfer is realized, the flexible deformation portion 3 is arranged between the bearing portion 1 and the supporting portion 2, the flexible deformation portion 3 plays a role in connecting the bearing portion 1 and the supporting portion 2, when the driving rod assembly 200 impacts the supporting portion 2, the flexible deformation portion 3 can generate flexible deformation, and the impact on the driving rod assembly 200 is buffered. For the noise transmitted from the supporting part 2 to the bearing part 1, the noise reduction effect is achieved to a certain extent under the flexible deformation effect of the flexible deformation part 3, and a good noise reduction effect is ensured. Meanwhile, the flexible deformation portion 3 increases a noise propagation path, which is equivalent to increase energy loss and reduce noise transmitted to the yoke plate 300.

Through yoke iron plate 300 is provided with storage tank 302, storage tank 302 is used for holding at least part of the gasket 100 of making an uproar that falls, and storage tank 302 is when the space that provides of the gasket 100 of making an uproar falls, and the lateral wall of storage tank 302 still plays the spacing effect of the gasket 100 of making an uproar that falls.

The inner wall of the receiving groove 302 and the noise reduction gasket 100 may be separated from each other and may be connected to each other by brazing, laser welding, resistance welding, or the like.

It is understood that the rigid material specifically refers to elastic fatigue-resistant materials such as metal stainless steel, beryllium copper, and the like, and specifically may be metals such as aluminum, copper, and the like, or carbon fiber, or hard plastics, and the like. The kind of the rigid material is not limited in this embodiment, and may be adjusted according to actual production needs, as long as the rubber cushion does not have large deformation, and the material with large structural strength and rigidity is within the protection scope of this embodiment.

It should be noted that, because the noise reduction pad 100 is made of a rigid material at least partially, the flexible deformation portion 3 is provided to achieve buffering and noise reduction on the basis that the noise reduction pad 100 is rigid, in other words, the flexible deformation portion 3 functions on the premise that the flexible deformation portion itself is rigid, and then the flexible noise reduction and buffering functions are achieved.

It is understood that the first direction specifically refers to the moving direction of the driving rod assembly 200, and may specifically be a vertical direction.

In one embodiment, either one of the support part 2 and the carrier part 1 is provided with a through hole 21, the through hole 21 being used for the penetration of the driving rod assembly 200. The through hole 21 provides an avoidance space for the movement of the driving rod assembly 200 along the first direction, so that the driving rod assembly 200 can move freely, and the flexibility of switching on and off of the relay is ensured. The through hole 21 may be a closed hole structure such as a circular hole, so as to prevent the driving rod assembly 200 from being separated from the through hole 21.

In one embodiment, as shown in fig. 3-5, the noise reduction spacer 100 further comprises a suspended portion 4, the suspended portion 4 being disposed between the carrier portion 1 and the support portion 2 in the first direction.

Through being provided with free space 4 between carrier part 1 and support part 2, support part 2 has certain suspension space for carrier part 1 promptly, when drive rod subassembly 200 impacted support part 2, can follow the first direction trace to a certain extent after support part 2 receives the impact and move down, and free space 4 provides the removal space for support part 2's removal to reach the striking that plays drive rod subassembly 200 cushioning effect.

It can be understood that the suspension portion 4 remains suspended after the relay releasing action is completed and the collision buffer is performed, that is, the suspension portion 4 actually starts the buffer function, and does not directly transmit the impact to the yoke plate 300.

Specifically, the bottom surface of the support part 2 is higher than the bottom surface of the carrier part 1 in the first direction, so that a suspended part 4 is formed between the support part 2 and the carrier part 1.

It is understood that if the difference in height of the top surface of the support portion 2 with respect to the yoke plate 300 is just equal to the material thickness of the material of the blank of the noise reducing shim 100. The thickness of the green material is specifically the thickness of the above rigid material. At this time, when the driving lever assembly 200 generates an impact force to the supporting portion 2, since the supporting portion 2 is stacked on the bearing portion 1, and the supporting portion 2 and the bearing portion 1 are in contact with each other, the impact force is transmitted to the yoke plate 300 through the supporting portion 2 and the bearing portion 1, and the noise reduction and buffering effects are poor.

The bottom surface of the support part 2 is higher than the bottom surface of the carrier part 1, i.e. the support part 2 is not simply stacked on the carrier part 1, and the carrier part 1 and the support part 2 are not in the same plane. In other words, in the first direction, the height of the top face of the support portion 2 with respect to the yoke plate 300 is greater than the material thickness of the material blank of the noise reduction shim 100. At this moment, when the drive rod assembly 200 produced the impact force to supporting part 2, because supporting part 2 has certain unsettled for carrier 1, supporting part 2 and carrier 1 both do not have large tracts of land direct contact each other, utilize suspension 4 to realize the buffering behind the impact supporting part 2 that the impact force supports, and on the large tracts of land transmitted to yoke plate 300 board through carrier 1, the improvement was fallen and is made an uproar and cushioning effect.

It can be understood that the bottom surface of the supporting portion 2 may be higher than the top surface of the carrying portion 1, and the bottom surface of the supporting portion 2 may also be lower than the top surface of the carrying portion 1, as long as the bottom surface of the supporting portion 2 is suspended in the air. However, when the bottom surface of the support portion 2 is flush with the top surface of the carrier portion 1, it is necessary that the bottom surface of the support portion 2 and the carrier portion 1 are not in direct contact with each other, and they need to be offset by a certain distance to provide a required accommodation space for the flexible deformation portion 3.

In one embodiment, as shown in fig. 3-5, the projection of the bearing part 1 on the yoke plate 300 and the projection of the support part 2 on the yoke plate 300 are not coincident.

By arranging the projection of the bearing part 1 on the yoke iron plate 300 and the projection of the support part 2 on the yoke iron plate 300 to be misaligned, the support part 2 and the bearing part 1 are misaligned structures, that is, the outer shapes of the support part 2 and the bearing part 1 enclose a cylindrical structure, but the bearing part 1 and the support part 2 are staggered with each other, so as to provide a receiving space for the flexible deformation part 3 between the bearing part 1 and the support part 2.

In one embodiment, the supporting portion 2, the flexible deformation portion 3 and the carrying portion 1 are sleeved with each other along the circumferential direction of the first direction.

In other words, the supporting portion 2, the bearing portion 1 and the flexible deformation portion 3 are similar to annular structures in shape, the supporting portion 2, the bearing portion 1 and the flexible deformation portion 3 are all annularly arranged around the driving rod assembly 200, and the impact force generated after the driving rod assembly 200 impacts the supporting portion 2 is uniformly and uniformly dispersed around the supporting portion 2 and then uniformly dispersed around the bearing portion 1 through the flexible deformation portion 3, so as to ensure the uniform dispersion of noise transmission.

In one embodiment, as shown in fig. 3-5, the flexible deformation portion 3 comprises a connecting plate 31, the connecting plate 31 is located between the bearing portion 1 and the support portion 2, and the connecting plate 31 is connected to the bearing portion 1 and the support portion 2 respectively.

Through being provided with connecting plate 31 between load-bearing part 1 and supporting part 2, connecting plate 31 plays load-bearing part 1 and supporting part 2 intermediate junction's effect to make whole noise reduction gasket 100 be monolithic structure, avoid load-bearing part 1 and supporting part 2 to the condition that needs the installation of fixing a position respectively for split type structure. Meanwhile, since the conventional driving lever assembly 200 directly impacts the yoke plate 300 when partially released, the connecting plate 31 acts as a transition zone between the bearing part 1 and the supporting part 2, so that noise from the supporting part 2 is prevented from being directly transmitted to the bearing part 1 and then transmitted to the yoke plate 300, which is equivalent to increasing a noise transmission path and playing a role in reducing noise transmission.

In one embodiment, as shown in fig. 3-5, the connecting plate 31 is at least partially provided with corrugations 32, the corrugations 32 being adapted to absorb and dampen the noise transmitted from the support portion 2 to the carrier portion 1 and to cushion the impact of the drive rod assembly 200.

The connecting plate 31 is at least partially provided with the corrugated structure 32, so that the surface of the connecting plate 31 forms a structure similar to a corrugation, impact force is generated when the driving rod assembly 200 impacts the supporting part 2, kinetic energy generated by part of the impact force is converted into oscillation energy of the corrugated structure 32, the direct conversion of the part of the energy into noise is reduced, and the function of generating less noise is realized. Meanwhile, the sound transmission needs to be filtered by the corrugated structure 32 before being transmitted to the yoke plate 300 through the bearing part 1, so that the energy is further reduced, and the noise transmission is slowed down.

Specifically, the connection plate 31 is provided with at least one of grooves and projections to form the corrugated structure 32.

The surface of the connecting plate 31 is provided with a groove or a protrusion, the groove wall of the groove or the side wall of the protrusion is equivalent to increase a noise transmission path, and the joint of two adjacent groove walls in the groove or the joint of two adjacent side walls in the protrusion plays a role in blocking noise and noise filtering. It is understood that the connecting plate 31 may be provided with grooves and protrusions, the number of the protrusions and the grooves is not limited to one, and the surface of the connecting plate 31 is formed into a wave-shaped or zigzag or square wave-shaped structure, which improves noise emission and transmission.

In one embodiment, as shown in fig. 6-8, in the first direction, the thickness of the connecting plate 31 is smaller than the thickness of the support part 2, and the thickness of the connecting plate 31 is smaller than the thickness of the carrier part 1.

In other words, the thicknesses of the connecting plate 31, the supporting portion 2 and the bearing portion 1 are not completely the same, and the connecting plate 31 has an effect of locally thinning the supporting portion 2 and the bearing portion 1, which is equivalent to that the noise reduction spacer 100 has a "dumbbell-shaped" structure with thick ends and thin middle, thereby improving the flexible deformation effect of the flexible connecting portion and further reducing sound transmission. It can be understood that the thickness of the local area corresponding to the connecting plate 31 is reduced for absorbing and stopping the noise transmitted from the supporting portion 2 to the carrying portion 1 and buffering the impact of the driving rod assembly 200.

In one embodiment, the thickness of the connecting plate 31 in the first direction gradually decreases from the bearing portion 1 to the support portion 2; or, the thickness of the connection plate 31 in the first direction gradually increases from the bearing part 1 to the support part 2.

In other words, the connecting plate 31 itself is not of an equal cross-section structure, and the thickness of the connecting plate 31 itself is also variable, so that the deformation amount of the connecting plate 31 is increased, and the flexible deformation effect of the flexible connecting part is further improved, thereby achieving the purpose of reducing sound transmission.

It will be appreciated that in some other embodiments, the thickness of the connecting plate 31 in the first direction may also remain constant from the load-bearing part 1 to the support part 2.

In one embodiment, as shown in fig. 9 to 11, the flexible deformation portion 3 further includes a hollow portion 33, and the hollow portion 33 is located between the bearing portion 1 and the support portion 2 for blocking noise transmitted from the support portion 2 to the bearing portion 1 and buffering impact on the driving rod assembly 200.

Through being provided with fretwork portion 33 between supporting part 1 and supporting part 2, fretwork portion 33 plays the effect of keeping apart between supporting part 2 and the supporting part 1, and under the effect of fretwork portion 33, the noise can't be transmitted to supporting part 1 from supporting part 2 through fretwork portion 33, realizes the effect of blocking of noise, plays the effect of restraining sound propagation to reduce the noise that transmits to supporting part 1 from supporting part 2.

In one embodiment, as shown in fig. 9-11, a plurality of connecting plates 31 are arranged at intervals between the bearing part 1 and the supporting part 2, and a hollow part 33 is formed between two adjacent connecting plates 31.

In other words, the connection plate 31 may be an integral structure (as shown in fig. 6 to 8), the connection plate 31 of the integral structure is specifically an annular structure, the connection plate 31 may also be a split structure (as shown in fig. 9 to 11), the number of the connection plates 31 of the split structure is multiple, the multiple connection plates 31 are annularly arranged around the support portion 2 at intervals, that is, a certain interval is provided between two adjacent connection plates 31, and at this time, the interval is the hollow portion 33. It can be understood that the noise generated by the driving rod assembly 200 impacting the supporting portion 2 is divided into two parts, one part is transmitted to the bearing portion 1 through the connecting plate 31, the connecting plate 31 plays a role of prolonging the noise propagation path while playing a role of connecting the supporting portion 2 and the bearing portion 1, the other part is blocked by the hollow portion 33 to play a role of inhibiting the noise propagation, and under the combined action of the two parts, the purpose of reducing the noise is achieved.

In one embodiment, as shown in fig. 9 to 11, the width of the connecting plate 31 in the first-direction circumferential direction gradually decreases in the direction from the bearing portion 1 to the support portion 2; or, the width of the connecting plate 31 in the first direction circumferential direction gradually increases from the bearing part 1 to the support part 2.

To the connecting plate 31 of split type structure, the width of connecting plate 31 also can not be the structure of constant width to make the connecting plate 31 different for the deflection of the different radius positions of actuating lever subassembly 200, be favorable to reducing stress concentration, promote the fatigue life who falls the gasket 100 of making an uproar, and simultaneously, further improve the deformation of flexible deformation portion 3, receive actuating lever subassembly 200 at supporting part 2 and strike the back, utilize flexible deformation portion 3 to have great deflection, improve buffering and noise reduction effect.

In some other embodiments, the width of the connecting plate 31 in the circumferential direction of the first direction may also remain constant from the bearing portion 1 to the support portion 2.

It should be particularly noted that the flexible deformation portion 3 has relative flexibility, and the connection plate 31 of the flexible deformation portion 3 respectively adopts hollow, wavy and thinning forms to realize the flexible deformation function, and all the functions are used for achieving the purpose of reducing sound transmission. It will be appreciated that the web 31 of the flexible deformation 3 may also be combined or superimposed in at least two of these three ways, further reducing the noise transmission.

In other words, the connecting plate 31 has both the corrugated structure 32 and the hollow portion 33, which corresponds to the flexible deformation portion 3 being a combination of hollow and wave. The noise generated by the driving rod assembly 200 impacting the supporting part 2 is divided into two parts, wherein one part of the noise is transmitted to the bearing part 1 through the corrugated structure 32 of the connecting plate 31, part of kinetic energy is converted into the oscillation energy of the corrugated structure 32, the direct conversion of the part of energy into the noise is reduced, the other part of the noise plays a role in inhibiting noise propagation due to the fact that the hollow part 33 obstructs a propagation path, and under the combined action of the two parts, the purpose of reducing the noise is achieved.

It should be particularly noted that the central angle of the corrugated structure 32 relative to the driving rod assembly 200 may be smaller than the central angle of the hollow-out portion 33 relative to the driving rod assembly 200 (as shown in fig. 12-14), so that the coverage area of the corrugated structure 32 is smaller than that of the hollow-out portion 33, and at this time, the hollow-out portion 33 plays a main role, and the corrugated structure 32 plays an auxiliary role; the central angle of the corrugated structure 32 relative to the driving rod assembly 200 may be larger than the central angle of the hollow portion 33 relative to the driving rod assembly 200 (as shown in fig. 15-17), so that the coverage area of the corrugated structure 32 is larger than that of the hollow portion 33, and at this time, the corrugated structure 32 plays a main role, and the hollow portion 33 plays an auxiliary role.

In one embodiment, the connecting plate 31 is provided with through holes, forming hollowed-out portions 33, as shown in fig. 15-17.

If the connection plate 31 is provided with through holes, the positions of the through holes correspond to hollowing out on the connection plate 31, so that the overall structural strength of the connection plate 31 is reduced, and the connection plate 31 can deform.

It is understood that the number of the through holes may be one or more, a plurality of through holes may be radially arranged around the driving rod assembly 200, and the through holes may be specifically long hole structures, and at this time, along the radial direction of the driving rod assembly 200, the length of the through holes is less than or equal to the distance between the supporting portion 2 and the bearing portion 1.

In one embodiment, the corrugations 32 and the hollows 33 are provided around the support 2 in a circumferential direction of the first direction.

When the corrugated structure 32 and the hollow portion 33 are disposed around the supporting portion 2, the noise generated by the driving rod assembly 200 impacting the supporting portion 2 is divided into two parts, one part of the noise is transmitted to the bearing portion 1 through the corrugated structure 32 of the connecting plate 31, the other part of the noise obstructs the transmission path due to the hollow portion 33, and because the radial distances between the corrugated structure 32 and the hollow portion 33 relative to the driving rod assembly 200 are approximately the same, the corrugated structure 32 and the hollow portion do not have a sequence, and both simultaneously play a role in reducing noise transmission, and under the combined action of the two parts, the purpose of reducing noise is achieved.

In one embodiment, as shown in fig. 15-17, the noise reduction shim 100 is provided with notches 5 in a radial direction of the drive rod assembly 200.

In other words, the projection of the notch 5 on the plane where the bearing part 1 is located is any one of a C shape, a U shape and a V shape, the cross section of the notch 5 is any one of a C shape, a U shape and a V shape, the notch 5 is an opening structure, which is equivalent to forming a notch on the edge of the noise reduction gasket 100, and the notch directly penetrates through the bearing part 1, the supporting part 2 and the flexible deformation part 3, so that the processing is simple, and the deformation amount is relatively large.

In one embodiment, as shown in fig. 15-17, the notch 5 communicates with the perforation 21.

The notch 5 is communicated with the through hole 21, so that the through hole 21 is not limited to a closed hole structure, under the communication effect of the notch 5, the through hole 21 can also be an open structure, when the driving rod assembly 200 and the noise reduction gasket 100 are installed, the driving rod assembly 200 can enter the through hole 21 through the open end of the notch 5, or the noise reduction gasket 100 is separated from the parts at the two sides of the notch 5, so that the driving rod assembly 200 can be conveniently arranged in the through hole 21 in a penetrating manner. Meanwhile, the notches 5 communicate with the through holes 21, thereby further increasing the overall deformation of the noise reduction gasket 100.

The trumpet-shaped structure has a small opening end and a large opening end, the large opening end of the trumpet-shaped structure is arranged towards the yoke iron plate 300, and the large opening end of the trumpet-shaped structure is the opening end. At this time, the supporting portion 2 is protruded relative to the bearing portion 1, and since the diameter of the bearing portion 1 or the distance from the edge of the bearing portion 1 to the driving rod assembly 200 is relatively large, the impact force received by the supporting portion 2 is expanded to a relatively large range while a good bearing effect is ensured, so that a dispersion effect is achieved, and the purpose of reducing noise is achieved.
