Description

Technical Field

[0001] This application relates to the field of gaskets, and more particularly to an auxiliary gasket structure. Background Technology

[0002] Plastic gaskets for windshield wiper motors are typically installed between the motor and the mounting bracket or windshield. Through precise design and calculation, the thickness, shape, and size of the gasket can be determined to achieve optimal vibration damping and noise reduction.

[0003] However, existing gaskets cannot adjust their thickness according to the specific needs of the motor, the working environment, and the installation space. Therefore, the vibration reduction and noise reduction effect may not be optimal, and the installation is also limited. Utility Model Content

[0004] To address the issues of unadjustable gasket thickness, which may prevent optimal vibration damping and noise reduction, and limited installation, this application provides an auxiliary gasket structure.

[0005] The auxiliary gasket structure provided in this application adopts the following technical solution:

[0006] An auxiliary gasket structure includes a pair of cavities 1 formed on the left and right sides of the top of a second gasket. A pair of threaded holes are formed on the top of the first gasket corresponding to the positions of the pair of cavities 1. An insert A is provided in each of the pair of cavities 1, and an insert B is provided in each of the pair of threaded holes. The first gasket is fixedly installed on the top of the second gasket by the snap-fit ​​of the insert A and the insert B. The insert A includes a conical block fixed to the top of each fork of the bifurcated elastic mandrel. The insert B includes a movable rod threaded into the threaded hole for tightening the bifurcated elastic mandrel. A conical groove is formed at the bottom of the movable rod, and an insert rod extending to the outside is rotatably installed inside the movable rod.

[0007] By adopting the above technical solution, the first gasket is superimposed on the top of the second gasket by the cooperation of the plug A and the plug B, which increases the overall thickness of the gasket. The thickened gasket is equivalent to adding a thicker buffer layer between the motor and the connecting parts, which can better absorb and disperse the vibration energy generated by the motor, reduce the degree of vibration transmission to the surrounding structure and air, and at the same time, the thickened gasket more effectively isolates the noise generated by the motor operation, preventing the noise from being transmitted to the external environment through the connection parts.

[0008] Preferably, a mounting base is fixedly connected to the bottom of the inner cavity of the cavity, and the bifurcated elastic mandrel is fixedly connected to the top of the mounting base by a mounting ring.

[0009] By adopting the above technical solution, the insertion rod passes through cavity one, the bifurcated elastic mandrel and the mounting ring and is inserted into the insertion hole, so that gasket one is neatly stacked on top of gasket two, making the bottom of gasket one fit with the top of gasket two.

[0010] Preferably, the surface of the movable rod is fixed with a thread that matches the shape of the threaded hole.

[0011] By adopting the above technical solution, through the cooperation of thread one and threaded hole, the movable rod will drive the insertion rod to move down continuously when the movable rod is rotated.

[0012] Preferably, the top of the mounting base has a mounting hole that matches the shape of the mounting rod.

[0013] By adopting the above technical solution, the movable rod drives the insertion rod to move downward continuously, and the tapered groove at the bottom of the movable rod is designed to match the tapered block on the bifurcated elastic mandrel. When the movable rod moves downward, the taper of the tapered groove gradually increases, and the contact area with the tapered block also gradually increases. Due to the increase in the taper of the tapered groove, it will exert an inward squeezing effect on the tapered block. This squeezing effect will cause the bifurcated piece of the bifurcated elastic mandrel to be subjected to a force that converges towards the center, thereby causing the bifurcated elastic mandrel to tighten as a whole. When the insertion rod moves downward into the insertion hole, the bifurcated elastic mandrel clamps and fixes the insertion rod, thereby fixing the first gasket on the top of the second gasket.

[0014] Preferably, the cavity is adapted to the shape of the movable rod.

[0015] By adopting the above technical solution, the movable rod can be inserted into the cavity.

[0016] Preferably, a hexagonal hole is provided at the center of the top of the movable rod.

[0017] By adopting the above technical solution, a hexagonal hole is opened at the top of the movable rod, which can be driven to rotate the movable rod with a hexagonal wrench, making it convenient to rotate the movable rod.

[0018] Preferably, the first gasket and the second gasket have the same shape and are both corrugated gaskets.

[0019] By adopting the above technical solution, gasket one and gasket two employ a waveform structure. This structure allows the gasket to effectively mitigate vibration and impact during the operation of mechanical equipment through variations in peaks and troughs. Therefore, waveform gaskets perform excellently in reducing equipment noise and preventing equipment damage.

[0020] Preferably, both gasket one and gasket two are made of polyetheretherketone (PEEK).

[0021] By adopting the above technical solutions, polyetheretherketone (PEEK) can maintain stable performance at high temperatures, with a typical temperature range of -50℃ to +260℃, and instantaneous temperatures reaching 315℃. This makes PEEK motor gaskets less prone to deformation, aging, and embrittlement in the high-temperature environment of motors, thus ensuring long-term stable operation of the motor. PEEK also possesses an extremely low coefficient of friction and excellent wear resistance. This reduces friction and wear between parts during motor operation, lowers energy consumption and noise, and extends the motor's service life.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By using connector A and connector B together, gasket 1 is fixedly installed on top of gasket 2, increasing the overall thickness of the gasket. The thickened gasket is equivalent to adding a thicker buffer layer between the motor and the connecting parts, which can better absorb and disperse the vibration energy generated by the motor, reduce the degree of vibration transmission to the surrounding structure and air, and at the same time, the thickened gasket more effectively isolates the noise generated by the motor operation, preventing the noise from being transmitted to the external environment through the connection parts.

[0024] 2. When the installation space is limited and the thickness of the shim needs to be reduced, a hex wrench can be used to rotate the movable rod counterclockwise. As the movable rod rotates, it moves upward continuously, and the compressive force acting on several conical blocks disappears. The bifurcated elastic mandrel springs back to its original position, and then the bifurcated elastic mandrel no longer clamps the fixed insertion rod. At this time, the second shim can be removed, the thickness of the shim can be reduced, and the shim can be installed in a narrow space. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] This application discloses an auxiliary gasket structure.

[0037] Reference Figures 1-5 An auxiliary gasket structure includes a pair of cavities 3 opened on the left and right sides of the top of the gasket 2, a pair of threaded holes 5 corresponding to the cavities 3 opened on the left and right sides of the top of the gasket 1, a mounting plug A4 set at the center of the bottom of the cavity 3, and a mounting plug B6 threaded in the threaded hole 5. The mounting plug A4 includes a conical block 44 fixed to the top of each fork of the bifurcated elastic spindle 43, a mounting seat 41 adapted to the shape of the cavity 3 fixedly installed at the bottom of the cavity 3, a mounting ring 42 fixedly connected to the center of the top of the mounting seat 41, and the bifurcated elastic spindle 43 fixedly connected to the center of the top of the mounting ring 42.

[0038] The insert B6 includes a movable rod 61 threaded into a threaded hole 5 for tightening the forked elastic spindle 43. A thread 62, which matches the shape of the threaded hole 5, is fixedly disposed on the surface of the movable rod 61. The movable rod 61 is threaded into the threaded hole 5 through the thread 62 fixed on its surface, and the bottom end of the movable rod 61 extends outward through the threaded hole 5. A tapered groove 67, which matches the shape of several tapered blocks 44, is opened in the center of the bottom of the movable rod 61. An installation hole 6, which matches the shape of the insert rod 65, is opened in the center of the interior of the movable rod 61. 4. The mounting hole 64 is connected to the tapered groove 67. The insertion rod 65 is rotatably installed in the mounting hole 64. The bottom end of the insertion rod 65 extends to the outside after passing through the mounting hole 64 and the tapered groove 67. The hexagonal hole 63 is opened in the center of the top of the movable rod 61. When the two movable rods 61 are inserted into the corresponding cavity 1 3, the bottom of the gasket 1 1 fits against the top of the gasket 2 2, and the surface of the movable rod 61 abuts against the inner surface of the cavity 1 3. The surface produces play, which prevents the movable rod 61 from shaking in the cavity 1 3 and improves the stability of the connection between the gasket 1 1 and the gasket 2 2.

[0039] Both gasket 1 and gasket 2 are corrugated gaskets made of polyetheretherketone (PEEK), and gasket 1 and gasket 2 are exactly the same in shape and size.

[0040] By inserting two movable rods 61 into the corresponding cavity 3, and installing gasket 1 on top of gasket 2, a hexagonal wrench adapted to the shape of the hexagonal hole 63 is used to drive the movable rods 61 to rotate clockwise. Because the thread 62 fixed on the surface of the movable rod 61 engages with the threaded groove in the threaded hole 5, the movable rod 61 continuously moves downwards while rotating. Furthermore, the tapered groove 67 at the bottom of the movable rod 61 is designed to match the tapered block 44 on each branch of the bifurcated elastic spindle 43. When the movable rod 6... As the cone moves downward, the taper of the conical groove 67 gradually increases, and the contact area with the conical blocks 44 also gradually increases. Due to the increase in the taper of the conical groove 67, it will exert an inward squeezing effect on the conical blocks 44. This squeezing effect will cause the bifurcated pieces of the bifurcated elastic spindle 43 to be subjected to a force that converges towards the center, resulting in the overall tightening of the bifurcated elastic spindle 43. When the movable rod 61 drives the insertion rod 65 to move downward into the insertion hole 45, the bifurcated elastic spindle 43 clamps and fixes the insertion rod 65.

[0041] Furthermore, during the tightening process of the forked elastic spindle 43, the tight fit between the conical groove 67 and the conical block 44 also plays a role in positioning and fixing, ensuring that the forked elastic spindle 43 can maintain a stable position and shape after tightening. This allows the insertion rod 65 to be clamped and fixed by the forked elastic spindle 43, thereby fixing the first gasket 1 on top of the second gasket 2, improving the stability of the connection between the first gasket 1 and the second gasket 2, and increasing the overall thickness of the gasket. The thickened gasket is equivalent to adding a thicker buffer layer between the motor and the connecting parts, which can better absorb and disperse the vibration energy generated by the motor, reduce the degree of vibration transmission to the surrounding structure and air, and more effectively isolate the noise generated by the motor operation, preventing the noise from being transmitted to the external environment through the connection part.

[0042] Furthermore, cavities 7 are provided on both the front and rear sides of the top of gasket 2. The same mounting plug A4 is fixedly installed at the bottom of cavity 7. If the thickness of the gasket needs to be further increased, another gasket 2 can be stacked on top of gasket 2. It should be noted that after rotating gasket 1 and gasket 2 by 90°, they can still completely overlap with the original shape. That is, when the upper gasket 2 is rotated 90° around its center point, it can still completely overlap with the lower gasket 2. The mounting plug B6 on the upper gasket 2 corresponds exactly to the lower gasket 2. The insert A4 is provided on the second gasket 2, which means that the two second gaskets 2 can be fixed together by the above method. Then, the required number of second gaskets 2 can be stacked to increase the overall thickness of the gasket. When the installation space is limited and the thickness of the gasket needs to be reduced, the hexagonal wrench can be used to drive the movable rod 61 to rotate counterclockwise, so that the movable rod 61 moves upward while rotating. At the same time, the squeezing force acting on several conical blocks 44 disappears, and the bifurcated elastic spindle 43 springs back to its original position. Then, the bifurcated elastic spindle 43 no longer clamps the fixed insert rod 65, so the second gasket 2 can be removed to reduce the thickness of the gasket.

[0043] Polyetheretherketone (PEEK) is a high-performance specialty engineering plastic. Due to its excellent properties such as high temperature resistance, chemical corrosion resistance, radiation resistance, high strength, high fracture toughness, and easy processing, as well as its small coefficient of linear expansion, flame retardancy, outstanding tribological properties, high wear resistance, insulation, and hydrolysis resistance, it is widely used in automotive parts, semiconductors, aerospace, petrochemicals, machinery, medical, and electronics industries.

[0044] The implementation principle of an auxiliary gasket structure in this application embodiment is as follows:

[0045] By inserting two movable rods 61 into the corresponding cavity 3, and installing gasket 1 on top of gasket 2, a hexagonal wrench that matches the shape of the hexagonal hole 63 is used to drive the movable rods 61 to rotate. The movable rods 61 move downwards while rotating, and the tapered groove 67 at the bottom of the movable rods 61 is designed to match the tapered blocks 44 on each of the bifurcated plates of the bifurcated elastic spindle 43. When the movable rods 61 move downwards, the taper of the tapered groove 67 gradually increases, and the contact area with the several tapered blocks 44 also gradually increases. Due to the increase in the taper of the tapered groove 67, it will exert an inward squeezing effect on the several tapered blocks 44. This squeezing effect will cause the bifurcated plates of the bifurcated elastic spindle 43 to be subjected to a force that converges towards the center, causing the bifurcated elastic spindle 43 to tighten as a whole. When the movable rods 61 drive the insertion rod 65 to move downwards into the insertion hole 45, the bifurcated elastic spindle 43 clamps and fixes the insertion rod 65, thereby fixing gasket 1 on top of gasket 2.

[0046] To improve the stability of the connection between gasket 1 and gasket 2, and to increase the overall thickness of the gaskets, the required number of gaskets 2 can be stacked as needed. The thickened gaskets are equivalent to adding a thicker buffer layer between the motor and the connecting parts, which can better absorb and disperse the vibration energy generated by the motor, reduce the degree of vibration transmission to the surrounding structure and air, and more effectively isolate the noise generated by the motor operation, preventing the noise from being transmitted to the external environment through the connection parts.

[0047] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
