Technical Field
[0001] The present application relates to the field of electric windows, and in particular to a vibration-reducing and noise-reducing pad and a mounting profile. Background Art
[0002] With the continuous progress of society, traditional window sashes can no longer meet the needs of modern life, and electric windows have gradually been widely used in thousands of households.
[0003] Existing electric windows are usually composed of components such as a rocker motor, a window sash, a rocker arm and a window frame. When installing the electric window, both ends of the rocker motor need to be directly fixed to the profile of the window sash so that the rocker motor is in direct contact with the profile.
[0004] However, during the opening and closing process of the electric window, the rocker motor will generate vibration when it is working. Since both ends of the rocker motor are in direct contact with the window sash profile, and the profile is usually made of metal material, the vibration will directly act on the profile. The vibration is quickly transmitted through the profile, thereby effectively transmitting the noise to the profile surface and diffusing to the outside, causing the electric window to make a lot of noise during use, seriously affecting the user experience and the comfort of the living environment.

[0038] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time.

[0039] The embodiment of the present application provides a vibration reduction and noise reduction pad, which includes:
[0040] A first vibration reduction part, used for abutting against the rocker arm motor;
[0041] A second vibration damping portion, used to abut against the mounting profile;
[0042] The deformation part, the first vibration reduction part and the second vibration reduction part are respectively arranged on two opposite sides of the deformation part;
[0043] The maximum cross-sectional area of the first vibration-damping portion and the maximum cross-sectional area of the second vibration-damping portion are both smaller than the maximum cross-sectional area of the deformation portion.
[0044] In this embodiment, when the rocker motor of the electric window is working, vibration is generated, and the vibration is firstly absorbed by the first vibration-damping part, which directly contacts the rocker motor, thereby effectively alleviating the transmission of the vibration.
[0045] The vibration absorbed by the first vibration-damping part is transmitted to the deformation part, and the deformation part further absorbs and buffers the vibration.
[0046] Finally, the vibration is transmitted to the second vibration damping portion, which contacts the profile and further absorbs the vibration to prevent the vibration from being transmitted to the profile.
[0047] Vibration-damping and noise-reducing pads can effectively absorb and alleviate vibrations, thereby reducing the noise of electric windows during use, greatly improving the comfort of using electric windows and reducing the interference of noise on the user's living environment.
[0048] Secondly, the vibration and noise reduction pads reduce the wear between the rocker arm motor and the profile, improving the overall durability and life of the electric window.
[0049] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0050] The embodiment of the present application provides a vibration reduction and noise reduction pad 100, and the vibration reduction and noise reduction pad 100 includes:
[0051] The first vibration reduction part 111 is used to abut against the rocker motor;
[0052] A second vibration damping portion 112, used to abut against the mounting profile;
[0053] The deformation part 113, the first vibration reduction part 111 and the second vibration reduction part 112 are respectively arranged on two opposite sides of the deformation part 113;
[0054] The maximum cross-sectional area of the first vibration-damping portion 111 and the maximum cross-sectional area of the second vibration-damping portion 112 are both smaller than the maximum cross-sectional area of the deformation portion 113 .
[0055] Please refer to Figure 1-Figure 3 In this embodiment, when the rocker motor of the electric window is working, vibration is generated. The vibration is firstly absorbed by the first vibration damping part 111, and the first vibration damping part 111 directly contacts the rocker motor, thereby effectively alleviating the transmission of the vibration.
[0056] The vibration absorbed by the first vibration-damping portion 111 is transmitted to the deformation portion 113 , and the deformation portion 113 further absorbs and buffers the vibration.
[0057] Finally, the vibration is transmitted to the second vibration damping portion 112, and the second vibration damping portion 112 contacts the profile to further absorb the vibration and prevent the vibration from being transmitted to the profile.
[0058] The vibration-damping and noise-reducing pad 100 can effectively absorb and alleviate vibrations, thereby reducing the noise during use of the electric window, greatly improving the comfort of use of the electric window, and reducing the interference of noise on the user's living environment.
[0059] Secondly, the vibration and noise reduction pad 100 reduces the wear between the rocker motor and the profile, thereby improving the overall durability and life of the electric window.
[0060] It should be noted that the vibration and noise reduction pad 100 is made of a wear-resistant flexible material, such as rubber, silicone and other materials.
[0061] The first vibration damping part 111 is roughly truncated cone-shaped, the second vibration damping part 112 is roughly truncated cone-shaped, and the first vibration damping part 111 and the second vibration damping part 112 are mirror-symmetrically arranged on two opposite sides of the deformation part 113. The deformation part 113 is roughly truncated cone-shaped.
[0062] When viewed from the direction from the first vibration damping part 111 to the second vibration damping part 112, the deformation part 113 completely blocks the first vibration damping part 111. When viewed from the direction from the second vibration damping part 112 to the first vibration damping part 111, the deformation part 113 completely blocks the second vibration damping part 112. Since the maximum cross-sectional areas of the first vibration damping part 111 and the second vibration damping part 112 are both smaller than the maximum cross-sectional area of the deformation part 113, the vibration transmission of the first vibration damping part 111 at the contact point is small, while the deformation part 113 has greater buffering and absorption capacity, effectively dispersing the vibration energy.
[0063] By means of the difference in cross-sectional area, the vibration absorption of the vibration-reducing and noise-reducing pad 100 is optimized, the overall vibration-reducing effect is enhanced, and the noise is further reduced.
[0064] The deformation part 113 is disposed between the first vibration damping part 111 and the second vibration damping part 112, and the two vibration damping parts are respectively located on opposite sides of the deformation part 113. The deformation part 113 can further disperse and weaken the transmission path of the vibration, provide additional vibration damping effect, and thus further reduce noise.
[0065] The first vibration damping portion 111 and the second vibration damping portion 112 are coaxially arranged.
[0066] In at least one embodiment of the present application, a maximum cross-sectional area of the first vibration damping portion 111 is less than or equal to a maximum cross-sectional area of the second vibration damping portion 112 .
[0067] Please refer to Figure 1-Figure 5 In this embodiment, when the rocker motor is working, vibration will be generated. The vibration is first transmitted to the first vibration damping part 111, and the vibration is transmitted from the first vibration damping part 111 to the deformation part 113. The deformation part 113 is located between the first vibration damping part 111 and the second vibration damping part 112, and has a greater buffering effect.
[0068] The vibration is finally transmitted to the second vibration damping part 112. Since the maximum cross-sectional area of the second vibration damping part 112 is greater than or equal to the first vibration damping part 111, its larger area design provides a stronger vibration damping effect, further absorbing and alleviating the vibration.
[0069] Through the multi-level absorption and buffering of the first vibration-damping part 111 , the deformation part 113 and the second vibration-damping part 112 , the vibration is greatly attenuated and the noise is effectively reduced.
[0070] When the maximum cross-sectional area of the first vibration damping portion 111 is equal to the maximum cross-sectional area of the second vibration damping portion 112 , the vibration is evenly distributed between the two vibration damping portions, effectively reducing the local concentration of vibration.
[0071] The same cross-sectional area ensures that there will be no significant energy concentration or dispersion during the vibration transmission process, maintaining a stable transmission path and helping to optimize the vibration reduction effect.
[0072] The same cross-sectional area allows the vibration energy to be evenly absorbed between the two vibration-damping parts, reducing the concentration of vibration energy caused by area differences, thereby optimizing the overall vibration-damping effect.
[0073] The vibration and noise reduction pad 100 is made more stable during the deformation process, the deviation or stress concentration caused by the inconsistent area of the deformation part 113 is reduced, and the stability and durability of the overall structure are improved.
[0074] The maximum cross-sectional area of the first vibration damping part 111 is smaller than the maximum cross-sectional area of the second vibration damping part 112 .
[0075] After the first vibration damping part 111 with a small area absorbs the initial vibration, the remaining vibration is transferred to the second vibration damping part 112 with a larger area. The second vibration damping part 112 can further absorb and alleviate the remaining vibration, thereby achieving a layer-by-layer absorption effect.
[0076] In at least one embodiment of the present application, the vibration and noise reduction pad 100 further includes a first positioning portion 114, a second positioning portion 115 fixedly connected to the first positioning portion 114, and a third positioning portion 116 fixedly connected to the second positioning portion 115;
[0077] The first positioning portion 114 is provided with a first vibration reduction portion 111, a second vibration reduction portion 112 and a deformation portion 113;
[0078] The second positioning portion 115 is provided with a first vibration reduction portion 111, a second vibration reduction portion 112 and a deformation portion 113;
[0079] The third positioning portion 116 is provided with a first vibration reduction portion 111, a second vibration reduction portion 112 and a deformation portion 113;
[0080] The first vibration reduction portion 111 of the first positioning portion 114 , the first vibration reduction portion 111 of the second positioning portion 115 , and the first vibration reduction portion 111 of the third positioning portion 116 are all located on the same plane.
[0081] Please refer to Figure 1-Figure 5 In this embodiment, when the rocker motor is working, vibration will be generated. Since all the first vibration damping parts 111 are in the same plane and receive vibration at the same time, the vibration energy is evenly distributed among the first vibration damping parts 111 of the first positioning part 114, the second positioning part 115 and the third positioning part 116.
[0082] The three positioning parts all preliminarily absorb and mitigate vibration through their first vibration-damping parts 111, second vibration-damping parts 112 and deformation parts 113. All first vibration-damping parts 111 are located in the same plane and receive vibration at the same time, ensuring uniform distribution and absorption of vibration, avoiding local vibration concentration, and providing the best vibration-damping effect.
[0083] Through multi-level vibration reduction and cushioning, the transfer of vibration energy is effectively reduced, noise propagation is reduced, and the noise reduction effect during use is improved.
[0084] The first vibration reduction portion 111 of the first positioning portion 114 , the first vibration reduction portion 111 of the second positioning portion 115 , and the first vibration reduction portion 111 of the third positioning portion 116 are all located on the same plane and receive vibration at the same time.
[0085] By ensuring that all the first vibration-damping parts 111 are on the same plane, the vibration can be evenly distributed to the first vibration-damping part 111 of each positioning part, providing a consistent vibration-damping effect and avoiding local vibration concentration.
[0086] In at least one embodiment of the present application, the second vibration reduction portion 112 of the first positioning portion 114 is protrudingly formed with a first positioning boss 1141 , and the first positioning boss 1141 is used for positioning and installation.
[0087] In at least one embodiment of the present application, the second vibration reduction portion 112 of the second positioning portion 115 is protrudingly formed with a second positioning boss 1151 , and the second positioning boss 1151 is used for positioning and installation.
[0088] In at least one embodiment of the present application, the length of the first positioning boss 1141 is denoted as a, and the length of the second positioning boss 1151 is denoted as b, satisfying the relationship: b>a.
[0089] In this embodiment, precise installation is performed using the positioning bosses (the first positioning boss 1141 and the second positioning boss 1151 ) on the first positioning portion 114 and the second positioning portion 115 .
[0090] The first positioning boss 1141 and the second positioning boss 1151 are respectively formed to protrude, ensuring that the vibration-damping pad can be firmly installed on the profile 120 to reduce looseness and displacement caused by vibration.
[0091] Since the length of the second positioning boss 1151 is greater than that of the first positioning boss 1141, the contact area between the second positioning boss 1151 and the mounting hole 120a of the mounting profile 120 is larger, and the friction between the second boss and the mounting hole 120a is greater, making the installation more secure.
[0092] The first positioning boss 1141 and the second positioning boss 1151 provide multi-point positioning to ensure that the vibration damping pad can be accurately installed, thereby improving installation accuracy and stability.
[0093] The first positioning boss 1141 and the second positioning boss 1151 provide stable installation positioning, ensuring that the vibration damping pad does not shift or loosen during the vibration transmission process, thereby significantly enhancing the vibration damping effect.
[0094] The first positioning boss 1141 and the second positioning boss 1151 are both cylindrical in shape. In other embodiments, they may be in other shapes to adapt to the shape of the mounting hole 120a.
[0095] In at least one embodiment of the present application, the first positioning portion 114 , the second positioning portion 115 , and the third positioning portion 116 are arranged in a triangle shape.
[0096] Please refer to Figure 1-Figure 5In this embodiment, the first positioning portion 114, the second positioning portion 115 and the third positioning portion 116 are arranged in a triangular shape, so that the vibration reduction and noise reduction pad 100 can be more firmly fixed on the mounting profile 120 during installation.
[0097] Since the first positioning portion 114, the second positioning portion 115 and the third positioning portion 116 are arranged in a triangle, the vibration energy is evenly distributed among the three positioning portions, and the vibration-damping components of each positioning portion (the first vibration-damping portion 111, the second vibration-damping portion 112 and the deformation portion 113) can effectively absorb and buffer the vibration.
[0098] The triangular arrangement provides even force distribution, allowing the vibration-damping components to absorb and damp vibrations more effectively, significantly enhancing the vibration-damping effect.
[0099] The triangular structure provides stable geometric support, making the vibration-damping and noise-reducing pad 100 more stable during installation and preventing displacement or loosening during vibration.
[0100] The triangular positioning part can evenly distribute the force, reduce local stress concentration, and improve the durability and service life of the vibration damping pad. It can also more effectively absorb vibration, reduce noise transmission, and improve the quiet effect during use.
[0101] In at least one embodiment of the present application, a first connecting portion 117 is provided between the first positioning portion 114 and the second positioning portion 115 , and a second connecting portion 118 is provided between the second positioning portion 115 and the third positioning portion 116 .
[0102] Please refer to Figure 1-Figure 5 In this embodiment, when the rocker motor is working, vibration is generated, and the vibration is transmitted to various parts of the vibration and noise reduction pad 100 through the first positioning portion 114, the second positioning portion 115 and the third positioning portion 116.
[0103] A first connecting portion 117 is provided between the first positioning portion 114 and the second positioning portion 115 , and a second connecting portion 118 is provided between the second positioning portion 115 and the third positioning portion 116 , so as to ensure that vibration energy is evenly distributed in the vibration-damping pad.
[0104] The first connection portion 117 and the second connection portion 118 ensure that the vibration energy is evenly distributed and absorbed in the vibration-damping pad, thereby reducing local vibration concentration and improving the vibration-damping effect.
[0105] The first connection portion 117 and the second connection portion 118 are both in a strip shape.
[0106] In at least one embodiment of the present application, a through hole 100 a is provided on the first positioning portion 114 , the second positioning portion 115 and the third positioning portion 116 .
[0107] A mounting profile 120 is used in any one of the vibration-damping and noise-reducing pads 100 described above. The mounting profile 120 is provided with three mounting holes 120a, which correspond one to one with the three through holes 100a. The length of the mounting hole 120a is c, satisfying the relationship: b=c=2a.
[0108] In this embodiment, when the rocker arm motor is working, vibration is generated.
[0109] The vibration and noise reduction pad 100 is firmly installed on both sides of the profile by connecting the through hole 100 a with the mounting hole 120 a on the mounting profile 120 .
[0110] Ensure that the through holes 100 a of the first positioning portion 114 , the second positioning portion 115 and the third positioning portion 116 are accurately aligned with the three mounting holes 120 a on the mounting profile 120 to provide a stable connection.
[0111] The first positioning boss 1141 of the vibration-damping and noise-reducing pad 100 on one side and the first positioning boss 1141 of the vibration-damping and noise-reducing pad 100 on the other side are located in the same mounting hole 120a, while the other two second positioning bosses 1151 are located in the other two mounting holes 120a, thereby avoiding interference to achieve positioning installation. It should be noted that the two vibration-damping and noise-reducing pads 100 on both sides are opposite and distributed in opposite directions, and one of the first vibration-damping parts 111 of the two vibration-damping and noise-reducing pads 100 abuts against the rocker motor, and the other abuts against the external fastener. Ensure that during the installation process, the vibration-damping and noise-reducing pads 100 can be effectively fixed to provide the best vibration reduction effect.
[0112] The mounting holes 120a on the mounting profile 120 correspond one-to-one with the through holes 100a of the vibration and noise reduction pad 100, ensuring accurate docking during installation, improving installation efficiency and stability, and ensuring that the vibration reduction pad is in the correct position during installation to reduce the reduction in vibration reduction effect caused by installation deviation.
[0113] Please refer to Figure 5 The external fastening screws sequentially penetrate the mounting hole 120a and the through hole 100a and are fixed to the rocker motor 130 to install the vibration reduction and noise reduction pad 100 between the rocker motor 1330 and the mounting profile 120.
[0114] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
