Description

Technical Field

[0001] This utility model relates to the field of electronic control device technology, and more specifically, to a noise reduction pad and a relay. Background Technology

[0002] A relay is an electronic control device commonly used in automatic control circuits. A relay consists of a control system and a controlled system. The control system acts as the input circuit, and the controlled system acts as the output circuit. Essentially, it uses a smaller current to control a larger current, achieving the function of "automatic switching."

[0003] In practical use, when the coil drive is energized, the moving iron core becomes an electromagnet and quickly attracts the yoke plate or stationary iron core. The gap between the moving iron core and the yoke plate or stationary iron core is called the magnetic gap; the smaller the magnetic gap, the greater the attraction. Throughout the energizing process, the acceleration and velocity of the moving iron core continuously increase, resulting in a large final impulse, which can cause significant "closing noise."

[0004] Before disconnecting, the relay is in a fully closed state with its contacts and core completely closed. The large spring is compressed beyond its travel to provide contact pressure, and the small spring is also compressed to provide contact breaking force. At this time, both springs are compressed, storing their potential energy. If the relay coil drive terminal is de-energized, the energy stored in the springs will be converted into the kinetic energy of the entire drive rod assembly, thereby achieving relay contact separation. The entire movement only stops when the drive rod assembly strikes the yoke plate (or other stop element). Due to the large amount of energy, the impact force between the drive rod assembly and the yoke plate (or other stop element) is very large, resulting in a significant "release noise" generated by the relay during this process.

[0005] However, it is generally required that the switching sound of the relay be quiet enough to avoid a noisy experience for the user. Utility Model Content

[0052] One embodiment of the above-described utility model has at least the following advantages or beneficial effects:

[0053] 1. The noise reduction pad provided in this application uses a fixing part to fix the noise reduction pad, and by setting two flexible deformation parts, namely a first flexible deformation part and a second flexible deformation part, the two flexible deformation parts are set to be deformable in two opposite directions to play a buffering role, reduce the generation of noise, achieve the noise reduction effect in two directions, suppress the propagation of noise, improve the noise reduction effect, and even play a role in noise reduction.

[0054] Meanwhile, since the noise-reducing pad provided in this application employs two flexible deformation portions—a first flexible deformation portion and a second flexible deformation portion—and these two flexible deformation portions can deform in two opposite directions along the first direction under different states, different flexible deformation portions in the noise-reducing pad function in different states. If one flexible deformation portion fails, it does not affect the buffering effect of the other flexible deformation portion. Moreover, the noise-reducing pad can provide buffering in both impact directions generated during attraction and release. In other words, the noise-reducing pad provided in this application generates different force arms under different states, and when one force arm fails due to fatigue, it does not affect the buffering effect of the other force arm. Accordingly, the structural design in this application can improve the service life of the noise-reducing pad and even improve the structural performance of the device using the noise-reducing pad.

[0055] 2. In the noise reduction pad provided in this application, the fulcrum contacts the first object so that the second flexible deformable part deforms and buffers along the second branch direction within the first direction under the push of the first object, so as to play the role of buffering, noise reduction or even noise reduction.

[0056] 3. In the noise reduction pad provided in this application, at least a portion of the first flexible deformable portion is located on one side of the fixed portion in the second branch direction, for contacting the second object. The portion of the first flexible deformable portion located in the fixed portion in the second branch direction provides a certain amount of movement space for the movement of the second object in the first branch direction, thereby achieving a buffering effect against impacts with the second object. Simultaneously, the noise reduction pad provided in this application limits the displacement of the second object in the first direction using the noise reduction pad itself, eliminating the need for its components, thereby reducing the number of parts, assembly steps, and costs.

[0057] 4. In the noise-reducing pad provided in this application, a first lever arm is formed between the fulcrum or fixing part and the position where the first flexible deformable part contacts the second object; a second lever arm is formed between the fulcrum and the fixing part. Driven by the two different objects, the first and second objects, the noise-reducing pad generates different lever arms. When one lever arm fails due to fatigue, it does not affect the buffering effect of the other lever arm. At the same time, the first and second lever arms do not interfere with each other, and each flexible part can adjust its elastic force by adjusting the length of the lever arm, that is, it does not affect its dimension in the height direction, and therefore does not affect the dimension of other products.

[0058] 5. In the noise-reducing pad provided in this application, the fulcrum is located at the connection position between the second flexible deformation part and the first flexible deformation part. The noise-reducing pad can provide cushioning in both impact directions generated during attraction and release. Specifically, a first lever arm is formed between the fulcrum and the position of the first flexible deformation part used to contact the second object; a second lever arm is formed between the fulcrum and the fixing part. Driven by these two different objects, the noise-reducing pad provided in this application generates different lever arms. When one lever arm fails due to fatigue, it does not affect the cushioning effect of the other lever arm. Simultaneously, the first and second lever arms do not interfere with each other, and each flexible part can adjust its elastic force by adjusting the length of the lever arm, meaning it does not affect its height dimension, and therefore does not affect the dimensions of other products.

[0059] 5. In the noise reduction pad provided in this application, the first flexible deformable portion and the second flexible deformable portion are respectively connected to the fixing portion, and there is no connection between the first flexible deformable portion and the second flexible deformable portion. When one of the first flexible deformable portion or the second flexible deformable portion undergoes deformation buffering, the other will not move along the first direction, thereby making the structure of the noise reduction pad more reliable.

[0060] 6. In the noise reduction pad provided in this application, a first lever arm is formed between the fixing part and the position of the first flexible deformable part for contacting the second object; a second lever arm is formed between the fulcrum and the fixing part. Driven by the two different objects, the noise reduction pad provided in this application generates different lever arms. When one lever arm fails due to fatigue, it does not affect the buffering effect of the other lever arm. At the same time, the first lever arm and the second lever arm do not interfere with each other, and each flexible part can also adjust its elastic force by adjusting the length of the lever arm, that is, it does not affect its dimension in the height direction, and therefore does not affect the dimension of other products.

[0061] 7. This application makes the noise reduction pads at least partially made of rigid materials, which makes the flexible deformation part itself have greater strength, less prone to large deformation, good fatigue resistance, less prone to foreign matter, and long service life.

[0062] 8. The relay provided in this application has a noise reduction pad disposed between at least part of the drive rod assembly and the stationary iron core along a first direction. The noise reduction pad is fixed to the yoke plate, and the noise reduction pad itself limits the displacement of the stationary iron core in the first direction. No other parts are needed, thereby reducing the number of parts, assembly steps and costs. Attached Figure Description

[0102] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0103] This application provides a relay. For example... Figure 1 , Figure 2 , Figure 14 as well as Figure 26 As shown, the relay provided in this application embodiment includes a noise reduction pad 100 provided by any of the following technical solutions.

[0104] This application provides a noise reduction pad 100. This noise reduction pad 100 can be applied inside a relay, and of course, it can also be applied to other structures. Please refer to... Figure 2 refer to Figures 3 to 13 The structure shown, and the combination Figure 14 refer to Figures 15 to 25 The structure shown, and the combination Figure 26 refer to Figures 27 to 37 The noise reduction pad 100, as shown in the diagram, includes a fixing portion 110, a first flexible deformable portion 120, and a second flexible deformable portion 130. The first flexible deformable portion 120 is connected to the fixing portion 110, and in a first state, it deforms along a first branch direction Z1 within a first direction for buffering and noise reduction. The second flexible deformable portion 130 is connected to the fixing portion 110, and in a second state, it deforms along a second branch direction Z2 within the first direction for buffering and noise reduction. The second branch direction Z2 is opposite to the first branch direction Z1, and the second state differs from the first state. Figure 1 The midplane M is parallel to the first direction. Figure 28 The middle plane N1 and plane N2 are set in parallel, and both plane N1 and plane N2 are parallel to the first direction and perpendicular to plane M.

[0105] It is worth noting that the specific directions of the first branch direction Z1 and the second branch direction Z2 are not limited to those shown in the attached figures. Of course, the noise reduction pad 100 can also be used by flipping it. For example, the first branch direction Z1 and the second branch direction Z2 can be compared to... Figure 3 The directions are opposite, so that the first branch direction Z1 faces towards... Figure 3 Above, the second branch direction Z2 faces Figure 3 Below the middle.

[0106] It is understood that the fixing part 110 is used to connect with other structures to fix the noise reduction pad 100 relative to other structures, so as to realize the buffer deformation of the noise reduction pad 100 in the first state or the second state.

[0107] When the noise reduction pad 100 provided in this application is applied, the first flexible deformable portion 120 can deform and buffer along the first branch direction Z1 in the first direction in the first state to reduce noise; the second flexible deformable portion 130 can deform and buffer along the second branch direction Z2 in the first direction in the second state to reduce noise.

[0108] It should be noted that the noise reduction pad 100 provided in this application embodiment is fixed by the fixing part 110, and by providing two flexible deformation parts, namely the first flexible deformation part 120 and the second flexible deformation part 130, and setting the two flexible deformation parts to be deformable in two opposite directions, so as to play a buffering role, reduce the generation of noise, achieve the noise reduction effect in two directions, suppress the propagation of noise, improve the noise reduction effect, and even play a role in noise reduction.

[0109] Meanwhile, since the noise reduction pad 100 provided in this application embodiment employs two flexible deformation portions, a first flexible deformation portion 120 and a second flexible deformation portion 130, and these two flexible deformation portions can deform in two opposite directions along the first direction under different states, different flexible deformation portions in the noise reduction pad 100 function in different states. If one flexible deformation portion fails, it does not affect the buffering effect of the other flexible deformation portion. Moreover, the noise reduction pad can play a buffering role in both impact directions generated by attraction and release. In other words, the noise reduction pad 100 provided in this application embodiment generates different force arms under different states, and when one force arm fails due to fatigue, it does not affect the buffering effect of the other force arm.

[0110] Accordingly, the structural configuration in the embodiments of this application can improve the service life of the noise reduction pad 100, and even improve the structural performance of the device using the noise reduction pad 100.

[0111] In one embodiment of this application, such as Figure 6 As shown, the noise reduction pad 100 is provided with a fulcrum P, which is used to contact the first object located on the first branch direction Z1 side of the second flexible deformation part 130.

[0112] It should be noted that when the noise reduction pad 100 provided in this application is applied, the fulcrum P contacts the first object so that the second flexible deformable part 130 deforms and buffers along the second branch direction Z2 in the first direction under the push of the first object, so as to play the role of buffering, noise reduction or even noise reduction.

[0113] Please continue to refer to this. Figure 1 and Figure 2As shown in the structure, the relay provided in this application embodiment also includes a drive rod assembly 300, a yoke plate 200, and a stationary iron core 400, wherein: a noise reduction pad 100 is disposed between part of the drive rod assembly 300 and the stationary iron core 400, and a fixing part 110 is mounted on the yoke plate 200; the drive rod assembly 300 is movably oriented along a first direction through which the noise reduction pad 100, the yoke plate 200, and the stationary iron core 400 pass, and is configured as a second object in a first state to abut against the first flexible deformation part 120 along the first branch direction Z1; the stationary iron core 400 is oriented along the first direction through which the yoke plate 200 passes, and the stationary iron core 400 is a movable part in the first direction, and is configured as a first object in a second state to abut against the second flexible deformation part 130 along the second branch direction Z2.

[0114] When the noise reduction pad 100 provided in this application embodiment is applied to a relay, such as Figure 2 , Figure 14 as well as Figure 26 As shown, the noise-reducing pad 100 is disposed between a portion of the drive rod assembly 300 and the stationary iron core 400. It should be understood that the stationary iron core 400 is equivalent to a first object; the drive rod assembly 300 is equivalent to a second object; and both the stationary iron core 400 and the drive rod assembly 300 are movable parts in the first direction. Specifically, the drive rod assembly 300 is configured to have the noise-reducing pad 100 passing through it in the first direction and to abut against the first flexible deformable portion 120 in the first branch direction Z1; the stationary iron core 400 is configured to abut against the second flexible deformable portion 130 in the second branch direction Z2.

[0115] It is worth noting that the relay provided in this application embodiment places the noise reduction pad 100 between the drive rod assembly 300 and the stationary iron core 400 along the first direction, and fixes it with the yoke plate 200 by the fixing part 110 to limit the displacement of the stationary iron core 400 in the first direction. It does not require the use of other parts, thereby reducing the number of parts, reducing assembly steps, and reducing costs.

[0116] Specifically, when the drive rod assembly 300 is released, at least a portion of the drive rod assembly 300 impacts the first flexible deformation portion 120 of the noise reduction pad 100. Since the fixing portion 110 is mounted on the yoke plate 200, the impact point can be shifted. When the drive rod assembly 300 impacts the first flexible deformation portion 120, the first flexible deformation portion 120 can undergo flexible deformation along the first branch direction Z1 to buffer the impact of the drive rod assembly 300. For the noise generated during the impact between the drive rod assembly 300 and the yoke plate 200, the flexible deformation of the first flexible deformation portion 120 can achieve a certain degree of noise reduction, ensuring a good noise reduction effect. Moreover, the first flexible deformation portion 120 can increase the noise propagation path, increase energy loss, and reduce the noise transmitted to the yoke plate 200.

[0117] In static iron core 400 and such Figure 2 When the moving iron core 700 is attracted, it collides with the stationary iron core 400. Since the stationary iron core 400 is a movable part, it can move along the second branch direction Z2. When the stationary iron core 400 abuts against the second flexible deformation part 130, the second flexible deformation part 130 can undergo flexible deformation, which buffers the impact transmitted from the moving iron core 700 to the stationary iron core 400, thereby achieving a noise reduction effect. Moreover, the second flexible deformation part 130 can increase the noise propagation path, increase energy loss, and reduce the noise transmitted to the yoke plate 200.

[0118] In summary, the first flexible deformable portion 120 within the noise-reducing pad 100 provided in this application embodiment can undergo buffer deformation along the first branch direction Z1 to reduce noise from impacts on the drive rod assembly 300; simultaneously, the second flexible deformable portion 130 within the noise-reducing pad 100 can undergo buffer deformation along the second branch direction Z2 to reduce noise from impacts on the stationary iron core 400. Therefore, this application embodiment, through the noise-reducing pad 100 alone, can simultaneously achieve bidirectional noise reduction for both the drive rod assembly 300 and the stationary iron core 400.

[0119] To better understand the noise reduction pad 100 provided in the embodiments of this application, the following description will be based on the example of the noise reduction pad 100 being applied in a relay and used to perform bidirectional noise reduction on the drive rod assembly 300 and the stationary iron core 400.

[0120] According to some embodiments of the present invention, at least a portion of the first flexible deformable portion 120 is located on one side of the fixed portion 110 in the second branch direction Z2, for contacting the second object. It should be noted that, after the noise-reducing pad 100 provided in this application embodiment is assembled into the relay, the portion of the first flexible deformable portion 120 located on the fixed portion 110 in the second branch direction Z2 provides a certain amount of movement space for the movement of the second object, i.e., the drive rod assembly 300, in the first branch direction Z1, thereby achieving a buffering effect against impacts to the drive rod assembly 300. Simultaneously, the noise-reducing pad 100 provided in this application embodiment limits the displacement of the second object, i.e., the drive rod assembly 300, in the first direction using the noise-reducing pad 100 itself, without the need for any additional parts, thereby reducing the number of parts, assembly steps, and costs.

[0121] When setting the noise reduction pad 100 provided in the embodiments of this application, the structure of the noise reduction pad 100 can be in various forms. For example, it can be one of the following structural forms.

[0122] In structural form one, the first flexible deformable part 120 is connected to the fixed part 110 through the second flexible deformable part 130.

[0123] When using the noise-reducing pad 100 provided in this embodiment, for example, before the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise-reducing pad 100 relative to the yoke plate 200 is as follows: Figure 6 and Figure 7 As shown; after the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 is as follows. Figure 8 and Figure 9 As shown. Combined with Figures 6 to 9 The structure shown, compared to the state before the drive rod assembly 300 is released, the first flexible deformable part 120 deforms and buffers along the first branch direction Z1 in the first direction under the push of the drive rod assembly 300, so as to play a noise reduction function.

[0124] Before attraction, the static iron core 400 and the noise reduction pad 100 are in the following states relative to the yoke plate 200: Figure 10 and Figure 11 As shown; during the attraction process, the moving iron core 700 will collide with the stationary iron core 400. Since the stationary iron core 400 is a movable part in the first direction, it will move along the second branch direction Z2. Specifically, during the movement of the stationary iron core 400 along the second branch direction Z2, it will contact the second flexible deformation part 130, causing the second flexible deformation part 130 to deform. After the second flexible deformation part 130 is deformed, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 can be as follows. Figure 12 and Figure 13 As shown. Combined with Figures 10 to 13 The structure shown, compared to the state before attraction, allows the second flexible deformation part 130 to deform and buffer and reduce noise along the second branch direction Z2 within the first direction under the push of the stationary iron core 400.

[0125] According to some embodiments of this utility model, such as Figures 6 to 13 As shown, the fulcrum P is located at the connection point between the second flexible deformation part 130 and the first flexible deformation part 120.

[0126] When the drive rod assembly 300 is released, the first flexible deformable portion 120 can move and deform buffer along the first branch direction Z1 within the first direction under the push of the drive rod assembly 300. Since the fulcrum P is located at the connection position of the first flexible deformable portion 120 and the second flexible deformable portion 130, the fulcrum P also serves as a support point when the first flexible deformable portion 120 buffers its deformation. Specifically, during the buffering deformation process of the first flexible deformable portion 120, the portion between the first flexible deformable portion 120 and the fulcrum P forms as follows: Figure 6 The force arm L1 is shown.

[0127] It is worth noting that since the fulcrum P also serves as a support point when the first flexible deformation part 120 is buffering deformation, the second flexible deformation part 130 may undergo slight deformation during the movement of the first flexible deformation part 120 along the first branch direction Z1. The details will not be elaborated further.

[0128] During the attraction process between the moving iron core 700 and the stationary iron core 400, the fulcrum P abuts against the stationary iron core 400. The second flexible deformable part 130 can move and deform under the push of the stationary iron core 400 along the second branch direction Z2 within the first direction, providing a buffer. The portion between the fixed part 110 and the fulcrum P is formed as follows: Figure 10 The force arm L2 is shown.

[0129] It should be noted that the noise-reducing pad 100 in this embodiment can provide cushioning in both impact directions generated during attraction and release. Furthermore, in this structural form, a first lever arm L1 is formed between the fulcrum P and the position of the first flexible deformable part 120 that contacts the second object; a second lever arm L2 is formed between the fulcrum P and the fixed part 110. Driven by the two different objects, the noise-reducing pad 100 provided in this embodiment generates different lever arms. When one lever arm fails due to fatigue, it does not affect the cushioning effect of the other lever arm.

[0130] Meanwhile, the first lever arm L1 and the second lever arm L2 do not interfere with each other, and each flexible part can adjust its elastic force by adjusting the length of the lever arm, which means that it does not affect its dimensions in the height direction, and thus does not affect the dimensions of other products.

[0131] It is worth noting that when specifically setting the noise reduction pad 100, its elastic force can be adjusted by adjusting the length of the lever arm to control the size of the noise reduction pad 100 in the first direction, thereby facilitating the miniaturization of the device using the noise reduction pad 100 without affecting the size of other components.

[0132] According to some embodiments of this utility model, such as Figure 3 and Figure 6 As shown, at least a portion of the first flexible deformable portion 120 is a pleated structure, and at least a portion of the second flexible deformable portion 130 near the fulcrum P is a pleated structure, in order to optimize the buffer deformation of the first flexible deformable portion 120 and the second flexible deformable portion 130, and to improve the effect of noise release and propagation. The pleated structure can be an irregular shape change, a wavy shape, or may only contain a single arcuate surface; further details are omitted.

[0133] Of course, it is also possible to set only one of the first flexible deformation part 120 or the second flexible deformation part 130 as a pleated structure, which will not be elaborated further.

[0134] In structural form two, please refer to Figures 15 to 17 The structure shown is as follows, and please refer to... Figures 27 to 29 In the structure shown, the second flexible deformable part 130 and the first flexible deformable part 120 are respectively connected to the fixing part 110; at least a portion of the second flexible deformable part 130 is located on one side of the fixing part 110 in the first branch direction Z1.

[0135] It should be noted that in this embodiment, the first flexible deformable portion 120 and the second flexible deformable portion 130 are respectively connected to the fixing portion 110, and there is no connection between the first flexible deformable portion 120 and the second flexible deformable portion 130. When one of the first flexible deformable portion 120 or the second flexible deformable portion 130 undergoes deformation buffering, the other will not move along the first direction. Therefore, the structural reliability of the noise reduction pad 100 in this embodiment is higher.

[0136] It is worth noting that in this second structural form, within the noise-reducing pad 100 provided in this embodiment, a first lever arm L1 is formed between the fixing part 110 and the position of the first flexible deformable part 120 for contacting the second object; a second lever arm L2 is formed between the fulcrum P and the fixing part 110. Similarly, in this second structural form, driven by the two different objects, the first object and the second object, the noise-reducing pad 100 provided in this embodiment generates different lever arms. When one lever arm fails due to fatigue, it does not affect the buffering effect of the other lever arm. At the same time, the first lever arm L1 and the second lever arm L2 do not interfere with each other, and each flexible part can also adjust its elastic force by adjusting the length of the lever arm, that is, it does not affect its dimension in the height direction, and therefore does not affect the dimension of other products.

[0137] The specific positions of the first lever arm L1 and the second lever arm L2 in this second structural form will be further explained in conjunction with the structure of the noise reduction pad 100 described below.

[0138] In this second structural form, please refer to Figures 15 to 17 The structure shown has a fulcrum P in the second flexible deformable part 130 located on the side of the first branch direction Z1 of the fixed part 110.

[0139] When using the noise-reducing pad 100 provided in this embodiment, for example, before the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise-reducing pad 100 relative to the yoke plate 200 is as follows: Figure 18 and Figure 19 As shown; after the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 is as follows. Figure 20 and Figure 21 As shown.

[0140] Combination Figures 18 to 21The structure shown, compared to the state before the drive rod assembly 300 is released, the first flexible deformation part 120 deforms and buffers along the first branch direction Z1 in the first direction under the push of the drive rod assembly 300, shortening the distance with the stationary iron core 400 in the first direction, so as to play a noise reduction function.

[0141] Before attraction, the static iron core 400 and the noise reduction pad 100 are in the following states relative to the yoke plate 200: Figure 22 and Figure 23 As shown; during the attraction process, the moving iron core 700 will collide with the stationary iron core 400. Since the stationary iron core 400 is a movable part in the first direction, it will move along the second branch direction Z2. Specifically, during the movement of the stationary iron core 400 along the second branch direction Z2, it will contact the second flexible deformation part 130, causing the second flexible deformation part 130 to deform. After the second flexible deformation part 130 is deformed, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 can be as follows. Figure 24 and Figure 25 As shown.

[0142] Combination Figures 22 to 25 The structure shown allows the second flexible deformation section 130 to deform and buffer along the second branch direction Z2 within the first direction, under the push of the stationary iron core 400, compared to the state before attraction.

[0143] Based on the connection position between the second flexible deformable part 130 and the fixed part 110, this structural form 2 can be exemplary divided into the following two specific implementation methods.

[0144] In one specific implementation, please refer to [link / reference]. Figures 15 to 17 The structure shown has a second flexible deformable part 130 with a fixed end and a free end. The fixed end is connected to the fixed part 110, and the free end is located on one side of the fixed part 110 in the first branch direction Z1, with the fulcrum P located at the free end.

[0145] In this specific embodiment, when the stationary iron core 400 moves along the second branch direction Z2, it directly abuts against the fulcrum P located at the free end. Accordingly, driven by the stationary iron core 400, the fulcrum P located at the free end can move relatively freely along the second branch direction Z2 to optimize the buffering effect of the second flexible deformable part 130.

[0146] During the buffer deformation process of the first flexible deformation portion 120, the portion of the first flexible deformation portion 120 between the position where it contacts the second object and the fixed portion 110 is formed as follows: Figure 18 The force arm L1 is shown. The portion between the fixed part 110 and the fulcrum P is formed as follows. Figure 18 The force arm L2 is shown.

[0147] Please continue to refer to this. Figures 15 to 17 The structure shown has a second flexible deformable portion 130 with a hollowed-out area 131 to reduce the weight of the noise reduction pad 100 and further optimize the buffering effect of the second flexible deformable portion.

[0148] It is worth noting that the specific location of the hollowed-out area 131 can be set according to requirements. For example, Figure 15 The hollowed-out area 131 in the middle does not extend completely to the free end in order to ensure the area of ​​the fulcrum P located in the second flexible deformation part 130 and optimize the buffering effect.

[0149] In another specific implementation, please refer to Figures 27 to 29 The structure shown has a second flexible deformable part 130 with two fixed ends, each fixed end being connected to a fixed part 110, and a fulcrum P is located in the part of the second flexible deformable part 130 between the two fixed ends.

[0150] When using the noise-reducing pad 100 provided in this embodiment, for example, before the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise-reducing pad 100 relative to the yoke plate 200 is as follows: Figure 30 and Figure 31 As shown; after the drive rod assembly 300 is released, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 is as follows. Figure 32 and Figure 33 As shown.

[0151] Combination Figures 30 to 33 The structure shown, compared to the state before the drive rod assembly 300 is released, the first flexible deformation part 120 deforms and buffers along the first branch direction Z1 in the first direction under the push of the drive rod assembly 300, shortening the distance with the stationary iron core 400 in the first direction, so as to play a noise reduction function.

[0152] Before attraction, the static iron core 400 and the noise reduction pad 100 are in the following states relative to the yoke plate 200: Figure 34 and Figure 35 As shown; during the attraction process, the moving iron core 700 will collide with the stationary iron core 400. Since the stationary iron core 400 is a movable part in the first direction, it will move along the second branch direction Z2 and contact the fulcrum P. Specifically, during the movement of the stationary iron core 400 along the second branch direction Z2, it will contact the second flexible deformation part 130, causing the second flexible deformation part 130 to deform. After the second flexible deformation part 130 is deformed, the state of the stationary iron core 400 and the noise reduction pad 100 relative to the yoke plate 200 can be as follows. Figure 36 and Figure 37 As shown.

[0153] Combination Figures 34 to 37The structure shown allows the second flexible deformation section 130 to deform and buffer along the second branch direction Z2 within the first direction, under the push of the stationary iron core 400, compared to the state before attraction.

[0154] Specifically, during the buffer deformation process of the first flexible deformation portion 120, the portion of the first flexible deformation portion 120 between the position for contacting the second object and the fixed portion 110 is formed as follows: Figure 30 The force arm L1 is shown. The portion between the fixed part 110 and the fulcrum P is formed as follows. Figure 34 The force arm L2 is shown.

[0155] It is worth noting that in this specific embodiment, when the stationary iron core 400 moves along the second branch direction Z2, it directly abuts against the fulcrum P located between the two fixed ends, which can ensure the structural stability of the second flexible deformation part 130 relative to the fixed part 110 and avoid tearing of the second flexible deformation part 130 relative to the fixed part 110.

[0156] Of course, in this second structural form, at least a portion of the first flexible deformable part 120 can be a pleated structure, and at least a portion of the second flexible deformable part 130 near the fulcrum P can be a pleated structure, so as to optimize the buffer deformation and improve the effect of noise release and propagation.

[0157] In both structural forms one and structural forms two, the noise reduction pad 100 includes at least two first flexible deformable portions 120, which are spaced apart along the circumferential direction of the first direction.

[0158] It should be noted that when multiple first flexible deformable portions 120 are arranged circumferentially along the first direction, this structural layout allows the stress on the noise-reducing pad 100 to be dispersed by the multiple first flexible deformable portions 120 when it is impacted by the drive rod assembly 300. Each first flexible deformable portion 120 can bear a portion of the stress, preventing stress concentration in a certain area. This arrangement of spaced first flexible deformable portions 120 can effectively prevent the noise-reducing pad 100 from being damaged due to excessive local stress.

[0159] When specifically configuring the first flexible deformable portion 120 within the noise-reducing pad 100, the number of the first flexible deformable portion 120 can be set to 2, 3, 4, or other numbers. For example, as shown... Figure 3 The noise reduction pad 100 shown has four first flexible deformable portions 120, and the four first flexible deformable portions 120 are arranged circumferentially along the first direction, with open spaces between adjacent first flexible deformable portions 120; as shown Figure 15 and Figure 27The noise reduction pad 100 shown has two first flexible deformation portions 120, and the two first flexible deformation portions 120 are arranged circumferentially along the first direction, with a hollow space formed between adjacent first flexible deformation portions 120.

[0160] It is worth noting that the extension dimension of each first flexible deformation part 120 along the circumferential direction of the first direction needs to be set according to the requirements. If the dimension of the first flexible deformation part 120 in this direction is too large, it will cause the first flexible deformation part 120 to deform too little when it is abutted by the driven rod assembly 300, resulting in a decrease in the buffering effect. If the dimension of the first flexible deformation part 120 in this direction is too large, it will cause the first flexible deformation part 120 to deform too much when it is abutted by the driven rod assembly 300, which will easily cause excessive deformation and be difficult to recover, resulting in a decrease in the service life of the noise reduction pad 100.

[0161] In a specific embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, at least two first flexible deformable portions 120 in the noise reduction pad 100 are symmetrically arranged. It can be understood that the symmetrical arrangement of the two first flexible deformable portions 120 enables the noise reduction pad 100 to maintain better balance when subjected to force, which can improve the stability of the noise reduction pad 100 in the working state and reduce additional vibration or deformation caused by structural deviation.

[0162] In one embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, the noise-reducing pad 100 includes at least two second flexible deformable portions 130, which are spaced apart along the circumference of the first direction. Similarly, when multiple second flexible deformable portions 130 are spaced apart along the circumference of the first direction, this structural layout allows the stress to be dispersed by the multiple second flexible deformable portions 130 when the noise-reducing pad 100 is impacted by the stationary iron core 400. Each second flexible deformable portion 130 can bear a portion of the stress, preventing stress concentration in a certain area. This spaced arrangement of second flexible deformable portions 130 can effectively prevent the noise-reducing pad 100 from being damaged due to excessive local stress.

[0163] When specifically setting the second flexible deformable portion 130 within the noise reduction pad 100, the number of the first flexible deformable portions 120 can be set to 2, 3, 4, or other quantities.

[0164] In a specific embodiment, such as Figure 3 , Figure 15 as well as Figure 27As shown, at least two second flexible deformable portions 130 in the noise reduction pad 100 are symmetrically arranged. It can be understood that the symmetrical arrangement of the two second flexible deformable portions 130 enables the noise reduction pad 100 to maintain better balance when subjected to force, which can improve the stability of the noise reduction pad 100 in the working state and reduce additional vibration or deformation caused by structural deviation.

[0165] like Figure 3 , Figure 15 as well as Figure 27 As shown, at least two first flexible deformation portions 120 and at least two second flexible deformation portions 130 in the noise reduction pad 100 are symmetrical about the first center line, so as to further improve the stability of the noise reduction pad 100 in the working state and reduce additional vibration or deformation caused by structural deviation.

[0166] It is worth noting that different noise reduction pads 100 can be formed by combining the first flexible deformable part 120 and the second flexible deformable part 130 in different ways.

[0167] In one specific implementation, such as Figure 3 As shown, at least a portion of the second flexible deformable portion 130 is disposed around the first flexible deformable portion 120 along the circumferential direction of the first direction.

[0168] Specifically, such as Figure 3 As shown, the noise reduction pad 100 includes four first flexible deformation portions 120, and the four first flexible deformation portions 120 are symmetrically arranged.

[0169] In another specific embodiment, such as Figure 15 and Figure 27 As shown, the noise reduction pad 100 includes two first flexible deformation portions 120 and two second flexible deformation portions 130. The two first flexible deformation portions 120 are symmetrically arranged, and the two second flexible deformation portions 130 are symmetrically arranged.

[0170] like Figures 6 to 13 As shown, the noise reduction pad 100 is also provided with a first suspended portion 150 and a second suspended portion 160. Along the first direction, the second suspended portion 160 is located between the fulcrum P and the fixed portion 110, and is used to provide moving space for the buffer of the second flexible deformable portion 130, thereby achieving the buffering effect of impact on the stationary iron core 400. At least a portion of the first suspended portion 150 is located between the first flexible deformable portion 120 and the fulcrum P, and is used to provide moving space for the buffer of the first flexible deformable portion 120, thereby achieving the buffering effect of impact on the drive rod assembly 300.

[0171] like Figures 18 to 25 As shown, and as Figures 30 to 37As shown, along the first direction, the second suspended portion 160 is located between the fulcrum P and the fixed portion 110, and is used to provide movement space for the buffer of the second flexible deformable portion 130, thereby achieving a buffering effect on the impact of the stationary iron core 400; at least a portion of the first suspended portion 150 is located between the first flexible deformable portion 120 and the fixed portion 110, and is used to provide movement space for the buffer of the first flexible deformable portion 120, thereby achieving a buffering effect on the impact of the drive rod assembly 300.

[0172] According to some embodiments of this utility model, the first suspended part 150 and the second suspended part 160 remain suspended during the deformation and buffering process of the noise reduction pad 100 to ensure the buffering effect and improve the noise reduction level.

[0173] In one embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, the noise reduction pad 100 also includes a support portion 140, which is connected to the fixing portion 110 via a first flexible deformable portion 120. The support portion 140 is used to support a preset object.

[0174] In a specific embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, the support portion 140 is located on one side of the fixing portion 110 in the second branch direction Z2 and is used to contact the second object. The support portion 140 can increase the contact area between the noise reduction pad 100 and the drive rod assembly 300 during impact, thereby improving the contact stability between the drive rod assembly 300 and the noise reduction pad 100.

[0175] Specifically, when the drive rod assembly 300 impacts the noise-reducing pad 100, it primarily impacts the support portion 140, causing the first flexible deformation portion 120 connected to the support portion 140 to undergo buffer deformation. The noise generated at the support portion 140 is divided into two parts. One part is transmitted to the fixing portion 110 through the first flexible deformation portion 120, which acts as a connector between the support portion 140 and the fixing portion 110, and also extends the noise propagation path to increase energy loss and reduce the noise transmitted to the yoke plate 200. The other part blocks the propagation path through the perforations between adjacent first flexible deformation portions 120, thus suppressing noise propagation. Under the combined effect of these two parts, the goal of reducing noise is achieved.

[0176] In one embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, the support portion 140 is continuously arranged along the circumference of the first direction so as to effectively contact the drive rod assembly 300 from all directions when the drive rod assembly 300 impacts the support portion 140.

[0177] In one embodiment, such as Figure 3 , Figure 15 as well as Figure 27 As shown, the support portion 140 is provided with a first through hole 141 for the second object portion to pass through, so that at least a portion of the drive rod assembly 300 passes through the support portion 140, so that the drive rod assembly 300 can move in the first direction.

[0178] In one embodiment, the support portion 140 is at least one of a circle, an ellipse, or a polygon. For example, Figure 3 As shown, the support portion 140 is circular in shape.

[0179] In one embodiment, at least a portion of the noise-reducing pad 100 is made of a rigid material. It is understood that the rigid material specifically refers to elastic, fatigue-resistant materials such as stainless steel and beryllium copper, and may specifically be metals such as aluminum and copper, or carbon fiber, or rigid plastics. This embodiment does not limit the specific type of rigid material and can adjust it according to actual production needs. Any material that is not a rubber pad with large deformation, or one with high structural strength and rigidity, is within the scope of protection of this embodiment.

[0180] It should be noted that the noise reduction pad 100 provided in this application embodiment is made of at least a rigid material, which makes the flexible deformation part itself have greater strength, is not easy to produce large deformation, has good fatigue resistance, is not easy to produce foreign objects, and has a long service life.

[0181] For example, at least one of the first flexible deformable portion 120 and the second flexible deformable portion 130 is made of a rigid material.

[0182] In one embodiment, the noise reduction pad 100 is a one-piece structure.

[0183] It should be noted that the integrated structure avoids loosening and weak points at the joints caused by assembling multiple parts, making the noise reduction pad 100 more stable during operation and effectively reducing additional vibration and noise caused by structural instability.

[0184] Furthermore, this embodiment achieves good buffering and noise reduction effects while maintaining overall strength through the rational design of the flexible deformation part. The noise reduction pad alone can buffer the impact in both directions of attraction and release. This design effectively absorbs and disperses impact forces from components such as the drive rod assembly 300 and the stationary iron core 400, reducing vibration transmission.

[0185] In addition, the integrated structure simplifies the processing and installation, thereby reducing manufacturing costs and improving production efficiency.

[0186] In one embodiment, the noise reduction pad 100 is a metal pad, which has high reliability, high temperature resistance, and excellent fatigue resistance.

[0187] In one embodiment, such as Figure 2 As shown, the drive rod assembly 300 includes a push rod 310 and an insulating seat 320. The push rod 310 is movably disposed along a first direction through a noise reduction pad 100, a yoke plate 200, and a stationary iron core 400, and one axial end of the push rod 310 is connected to the insulating seat 320. Along the first direction, the noise reduction pad 100 is located between the insulating seat 320 and the stationary iron core 400.

[0188] It is worth noting that when the drive rod assembly 300 is released, at least a portion of the drive rod assembly 300 impacts the first flexible deformation portion 120 of the noise-reducing pad 100; essentially, the insulating seat 320 impacts the first flexible deformation portion 120 of the noise-reducing pad 100. When the insulating seat 320 impacts the first flexible deformation portion 120, the first flexible deformation portion 120 can undergo flexible deformation along the first branch direction Z1, thus buffering the impact of the drive rod assembly 300. For the noise generated during the impact between the insulating seat 320 and the yoke plate 200, the flexible deformation of the first flexible deformation portion 120 can achieve a certain degree of noise reduction, ensuring a good noise reduction effect. Moreover, the first flexible deformation portion 120 can increase the noise propagation path, increase energy loss, and reduce the noise transmitted to the yoke plate 200.

[0189] In one embodiment, such as Figure 2 As shown, the drive rod assembly 300 also includes a first elastic element 330 and a connecting bracket 340. The insulating seat 320 is also used to mount the first elastic element 330 and fix at least a portion of the connecting bracket 340. For example, the first elastic element 330 is a spring, the connecting bracket 340 has a U-shaped structure, the opening of the connecting bracket 340 faces the insulating seat 320, the lower end of the connecting bracket 340 is connected to the insulating seat 320, and the moving contact 500 is mounted in the connecting bracket 340 through the first elastic element 330. The connecting bracket 340 serves to limit the movement of the moving contact 500. The two ends of the first elastic element 330 abut against the insulating seat 320 and the moving contact 500 respectively, and the first elastic element 330 provides elasticity and a restoring function.

[0190] According to some embodiments of this utility model, such as Figures 4 to 6 As shown, the yoke plate 200 is provided with a second through hole 210, and at least a portion of the stationary iron core 400 passes through the second through hole 210 along the first direction; at least a portion of the second flexible deformation portion 130 in the noise reduction pad 100 is located on one side of the stationary iron core 400 in the second branch direction Z2, so as to limit the maximum displacement of the stationary iron core 400 in the second branch direction Z2.

[0191] It should be noted that the noise reduction pad 100 provided in this application embodiment can buffer the hard contact caused by the static iron core 400 impacting other fixing parts or yoke plate 200 during the process of the moving iron core 700 and the static iron core 400 being attracted together, so as to reduce the motion noise generated when the static iron core 400 moves.

[0192] According to some embodiments of the present invention, the wall of the second through hole 210 is provided with a protrusion, and the protrusion is located on one side of the second through hole 210 in the first branch direction Z1.

[0193] The stationary iron core 400 includes a main body and a protrusion. The protrusion is arranged around the main body in the circumferential direction in the first direction, and the protrusion is located at the end of the main body in the first direction close to the noise reduction pad 100. Along the first direction, the protrusion is located between the second flexible deformation part 130 and the protrusion, so as to selectively abut against the second flexible deformation part 130 or the protrusion.

[0194] It should be noted that in the embodiments of this application, the second flexible deformable part 130 and the protrusion limit the maximum movement position of the stationary iron core 400 in the first direction, so that the stationary iron core 400 forms a movable part.

[0195] In one embodiment, one of the fixing part 110 of the noise-reducing pad 100 and the yoke plate 200 is provided with a positioning post 220, and the other is provided with a positioning hole 111 corresponding to the positioning post 220, with the positioning post 220 passing through the positioning hole 111. For example, as shown... Figure 5 As shown, the yoke plate 200 is provided with positioning posts 220, and the noise reduction pad 100 is provided with positioning holes 111.

[0196] It should be noted that, in this embodiment of the application, by setting the positioning post 220 through the positioning hole 111, it can play the role of initial positioning between the noise reduction pad 100 and the yoke plate 200, and ensure the accuracy of the relative position between the noise reduction pad 100 and the yoke plate 200.

[0197] Of course, if a rigid connection is required between the noise reduction pad 100 and the yoke plate 200, the positioning post 220 can be used as a rivet, and the rivet passes through the positioning hole 111 to achieve a fixed connection between the noise reduction pad 100 and the yoke plate 200.

[0198] In one embodiment, the relay further includes: Figure 1 and Figure 2 As shown, there is a stationary contact 600 and a moving contact 500. The moving contact 500 is positioned on one side of the stationary contact 600 along a first direction, and the drive rod assembly 300 can push the moving contact 500 so that the moving contact 500 contacts or disengages from the stationary contact 600.

[0199] It should be noted that the relay also includes an insulating cover 800, which is disposed on the yoke plate 200. The stationary contact 600 passes through the insulating cover 800 and extends at least partially into the insulating cover 800. The insulating cover 800 provides a fixed position for the stationary contact 600. The drive rod assembly 300 is at least partially disposed within the insulating cover 800. The insulating cover 800 provides an insulating environment for the stationary contact 600, the moving contact 500, and the drive rod assembly 300.

[0200] In one embodiment, the relay provided in this application further includes an electromagnet unit (not fully shown in the figure), which includes a coil frame, a coil, a stationary iron core 400, and a moving iron core 700. The coil frame is hollow and cylindrical, and is formed of insulating material, with the coil surrounding the coil frame. The stationary iron core 400 is fixedly disposed in the central hole of the coil frame. The stationary iron core 400 and the moving iron core 700 are disposed opposite to each other, and the moving iron core 700 is movable along a first direction. The moving iron core 700 is connected to the drive rod assembly 300 and is attracted by the stationary iron core 400 when the coil is energized. The moving iron core 700 and the drive rod assembly 300 can be connected by screwing, riveting, welding, or other methods. A second elastic element is also provided between the moving iron core 700 and the push rod 310. The second elastic element is sleeved on the outside of the push rod 310 and serves as an elastic reset element.

[0201] In actual use, the relay is in a fully closed state before disconnection. The first elastic element 330 is compressed beyond its travel to provide contact pressure, and the second elastic element is also compressed to provide contact breaking force. At this time, both elastic elements are compressed, storing elastic potential energy. If the relay receives a power-off command, the stored elastic potential energy will be converted into the kinetic energy of the entire drive rod assembly 300, thereby achieving separation between the moving contact 500 and the stationary contact 600 in the relay.
