Description

Technical Field

[0001] This application relates to the field of vehicle pad technology, and in particular to a high-temperature resistant shock-absorbing pad. Background Technology

[0002] During vehicle operation, high-speed driving generates vibrations. To improve vehicle stability, vibration damping pads are often used. Furthermore, these pads are installed near the brake mechanism, which generates high temperatures during operation. To minimize damage from these high temperatures, high-temperature resistant vibration damping pads are essential.

[0003] In the prior art, the operator installs the shock absorber pad into the vehicle hood by screwing in bolts. The shock absorber pad usually includes a basic base plate, a shock absorber plate fixed to the surface of the base plate, and a reinforcing plate bonded to the shock absorber plate. The base plate abuts against the surface of the vehicle hood, and the reinforcing plate faces the part of the vehicle that is in use.

[0004] During prolonged use, the high temperature environment can cause the adhesion between the damping plate and the reinforcing plate to loosen, thereby reducing the tightness of the connection between the damping plate and the reinforcing plate. As the reinforcing plate gradually detaches from the damping plate, it reduces the damping effect of the reinforcing plate on the components of the vehicle with the floor plate. Summary of the Invention

[0005] To improve the tightness of the connection between the damping plate and the reinforcing plate, this application provides a high-temperature resistant damping pad.

[0006] This application provides a high-temperature resistant shock-absorbing pad, which adopts the following technical solution:

[0007] A high-temperature resistant shock-absorbing pad includes a base plate, a shock-absorbing plate on one side of the base plate, the base plate and the shock-absorbing plate being connected by a connecting component, a reinforcing plate on the surface of the shock-absorbing plate facing away from the base plate, the reinforcing plate being fixed to the shock-absorbing plate, and a plurality of connecting columns arranged between the shock-absorbing plate and the reinforcing plate. The shock-absorbing plate, the reinforcing plate and the connecting columns are all made of elastic material. The connecting columns are provided with buffer components. The connecting column includes a first connecting column fixed to the shock-absorbing plate and a second connecting column fixed to the reinforcing plate, and the first connecting column and the second connecting column are staggered.

[0008] By adopting the above technical solution, when the damping plate and the reinforcing plate are connected, connecting post one and connecting post two interlock, improving the tightness of the connection between the damping plate and the reinforcing plate. Subsequently, after connecting the damping plate to the base plate using the connecting assembly, the damping plate pad is bolted to the connection point of the vehicle hood, thereby increasing the service life of the damping plate and reinforcing plate connection to the vehicle. During vehicle operation, the elastic material of the damping plate, reinforcing plate, and connecting posts undergoes slight deformation under vibration, thus achieving a buffering effect. Through the gap between the connecting posts, when the damping plate and reinforcing plate receive impact force, the gap deformation generates partial buffering force, and the buffer assembly on the connecting post also generates partial buffering force as the connecting post is subjected to force, thereby improving the buffering effect.

[0009] Optionally, the buffer assembly includes a slider that slides within the connecting column and a buffer spring fixed to the slider. A groove is provided within the connecting column, and the bottom of the groove is fixed to the buffer spring.

[0010] By adopting the above technical solution, when the reinforcing plate is subjected to external impact force, the elastic reinforcing plate deforms under force and squeezes the connecting column. At the same time as the elastic connecting column deforms under force, the slider at the end of the connecting column is squeezed. The slider is squeezed by pressure and the buffer spring is compressed. The buffer spring deforms under force and converts the deformation potential energy into elastic potential energy, thereby generating elastic force to balance part of the impact force, thereby improving the buffering effect of the shock-absorbing pad.

[0011] Optionally, the buffer assembly further includes a buffer ring fixed circumferentially along the outer surface of the connecting post, wherein the surface of the buffer ring is provided with a plurality of buffer holes, and the plurality of buffer rings abut against each other.

[0012] By adopting the above technical solution, when connecting post one and connecting post two intersect, the circumferential buffer rings abut against each other, thereby reducing the gap between connecting post one and connecting post two, improving the connection tightness between connecting post one and connecting post two, and thus improving the connection strength between the shock absorber plate and the reinforcing plate. The opening shape of the buffer hole changes when under force, thereby buffering part of the force and improving the buffering effect on the vehicle. Simultaneously, when the gaps formed by multiple connecting blocks are inconsistent, the buffer holes squeeze against each other, thereby increasing the crowding of the gaps and further improving the connection tightness between the connecting posts.

[0013] Optionally, the connecting assembly includes a protrusion fixed to the surface of the shock-absorbing plate and a connecting hole opened on the surface of the base plate. The protrusion engages with the connecting hole, and a fastening ring is fixed circumferentially on the protrusion. A fastening groove adapted to the fastening ring is opened on the inner wall of the connecting hole. The fastening ring is movably connected to the fastening groove. Both the protrusion and the fastening ring are made of elastic material.

[0014] By adopting the above technical solution, when connecting the damping plate to the base plate, the operator presses the damping plate so that the protrusion slides in the connection hole until the fastening ring is engaged with the inner wall of the fastening groove. Then, the surface of the damping plate is fixed to the base plate by means of adhesion, which further improves the tightness of the connection between the base plate and the damping plate.

[0015] Optionally, the base plate has a plurality of mounting holes I located at the ends, and the surface of the damping plate has a plurality of mounting holes II opposite to the mounting holes I. The circumferential area of ​​the mounting holes II is larger than that of the mounting holes I, and the reinforcing plate is away from the mounting holes II.

[0016] By adopting the above technical solution, when installing the shock absorber plate onto the vehicle, it is simple and convenient to connect it by bolts through the first mounting hole. The second mounting hole is larger than the first mounting hole, thus exposing the surface of the abutment plate, reducing wear on the shock absorber plate during bolt installation, and increasing the service life of the shock absorber plate. At the same time, when the bolts are connected to the base plate, the obstruction of the elastic material of the shock absorber plate is reduced, improving the tightness of the connection.

[0017] Optionally, a plurality of reinforcing rods are fixed at the central axis along the length of the reinforcing plate, and the reinforcing rods are arranged alternately.

[0018] By adopting the above technical solution, the reinforcing rod strengthens the connection between the two sides of the long reinforcing plate, thereby reducing the possibility of the reinforcing plate breaking under long-term high temperature and vibration environment and improving the service life of the reinforcing plate.

[0019] Optionally, the damping plate is provided with a side plate that is adhered to the side wall of the base plate, and the side plate is integrally formed with the damping plate.

[0020] By adopting the above technical solution, the side panels wrap around the side walls of the base plate, thereby reducing the exposed area of ​​the base plate and improving its protective effect. At the same time, it enhances the tightness of the connection between the damping plate and the base plate.

[0021] Optionally, a high-temperature resistant cloth is adhered to the side of the base plate away from the shock-absorbing plate.

[0022] By adopting the above technical solution, the high-temperature resistant fabric protects one side of the base plate, thereby improving the high-temperature resistance of the base plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Connecting column one and connecting column two are fixed to the damping plate and the reinforcing plate respectively, and the two are interlocked, thereby improving the connection tightness between the damping plate and the reinforcing plate. At the same time, the gaps formed between the multiple connecting columns can change the shape of the gaps when the connecting columns are deformed by vibration and impact, thereby buffering and damping part of the vibration force and improving the damping and buffering effect of the damping pad.

[0025] 2. A buffer ring is axially fixed on the outer surface of the connecting column. The contact of multiple buffer rings enhances the tightness of the connection between the connecting columns. At the same time, the buffer ring reduces the gap between the connecting columns. Depending on the size of the space, the buffer holes in different parts of the buffer ring are compressed to varying degrees, thereby improving the tightness of the contact between the buffer rings.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a high-temperature resistant shock-absorbing pad.

[0032] Reference Figure 1 and Figure 2A high-temperature resistant shock-absorbing pad includes a base plate 1, a shock-absorbing plate 2 on one side of the base plate 1, and a connecting assembly 3 connecting the base plate 1 and the shock-absorbing plate 2. A reinforcing plate 4 is fixed to the surface of the shock-absorbing plate 2 facing away from the base plate 1. The shock-absorbing plate 2 has a side plate 22 that is adhered to the side wall of the base plate 1 and is integrally formed with the shock-absorbing plate 2. A high-temperature resistant cloth 23 is adhered to the side of the base plate 1 facing away from the shock-absorbing plate 2. The base plate 1 is bolted to the connection point on the vehicle, and the side with the high-temperature resistant cloth 23 is connected to the vehicle. The shock-absorbing plate 2 and the reinforcing plate 4 are located near the vehicle's brake mechanism, buffering and damping the vibration force generated by the brake operation during vehicle operation, thereby improving the vehicle's stability.

[0033] Reference Figure 1 and Figure 2 Both the damping plate 2 and the reinforcing plate 4 are made of polyurethane, which has the characteristics of impact resistance, wear resistance, oil resistance, and high strength, and can improve the overall service life of the damping pad. The high-temperature resistant cloth 23 is a ceramic fiber refractory cloth, which has a strong high-temperature resistance effect.

[0034] Reference Figure 1 and Figure 2 The base plate 1 has several mounting holes 11 at its ends, and the damping plate 2 has several mounting holes 21 opposite to the mounting holes 11. The circumferential area of ​​the mounting holes 21 is larger than that of the mounting holes 11. The reinforcing plate 4 is located away from the mounting holes 21, thus partially exposing the surface of the base plate 1 for easy bolt installation. This also reduces the risk of heat conduction and corrosion of the elastic material damping plate 2 due to long-term exposure of bolts to high temperatures.

[0035] Reference Figure 1 and Figure 2 The connecting component 3 includes a protrusion 31 fixed to the surface of the shock-absorbing plate 2 and a connecting hole 32 opened on the surface of the base plate 1. The protrusion 31 is engaged with the connecting hole 32, making it easy for the operator to apply force to slide the protrusion 31 until it fits against the inner wall of the connecting hole 32. A fastening ring 311 is fixed circumferentially to the protrusion 31. A fastening groove 321 adapted to the fastening ring 311 is opened on the inner wall of the connecting hole 32. The fastening ring 311 and the fastening groove 321 are movably connected. Both the protrusion 31 and the fastening ring 311 are made of polyurethane, which has good elasticity. Under the movement of the protrusion 31, the fastening ring 311 is squeezed and slides in the connecting hole 32 until its end abuts against the outer wall of the fastening groove 321. Under its own elastic force, it expands to abut against the inner wall of the fastening groove 321, thereby improving the tightness of the connection between the protrusion 31 and the inner wall of the connecting hole 32.

[0036] Reference Figure 2 and Figure 3A number of connecting posts 41 are arranged between the damping plate 2 and the reinforcing plate 4. The connecting posts 41 include a first connecting post 411 fixed on the damping plate 2 and a second connecting post 412 fixed on the reinforcing plate 4. The first connecting post 411 and the second connecting post 412 are staggered and interlocked with each other. A gap is formed between the first connecting post 411 and the second connecting post 412 for interlocking. The connection between the damping plate 2 and the reinforcing plate 4 is intersected, thereby improving the tightness of the connection between the damping plate 2 and the reinforcing plate 4.

[0037] Reference Figure 2 and Figure 3 A buffer ring 53 is fixed circumferentially along the outer surface of the connecting post 41. Several buffer rings 53 abut against each other, reducing the size of the gap between the connecting posts 41 and improving the tightness of the connection. Several buffer holes 531 are formed on the surface of the buffer rings 53. The spatial shape of the gap formed between the connecting posts 41 is irregular. When buffer rings 53 at different positions abut against each other, they compress the buffer holes 531 on different buffer rings 53 to varying degrees. Simultaneously, when the shock-absorbing pad is subjected to external impact, the shape of the gap changes, further compressing the buffer holes 531, causing them to deform. This improves the buffering effect and enhances the adaptability of multiple buffer rings 53 abutting against each other.

[0038] Reference Figure 2 and Figure 3 The connecting post 41 is equipped with a buffer assembly 5, which includes a slider 51 that slides within the connecting post 41 and a buffer spring 52 fixed to the slider 51. The buffer assembly 5 also includes a buffer ring 53. A groove 413 is formed inside the connecting post 41, and the bottom of the groove 413 is fixed to the buffer spring 52. When the connecting post 41 undergoes elastic deformation under external impact, the slider 51 at the end is squeezed and moves towards the bottom of the groove 413, thereby squeezing the buffer spring 52. The buffer spring 52 deforms under pressure, thereby converting deformation potential energy into elastic potential energy to balance part of the impact force, thus improving the damping effect of the shock absorber on vehicle vibration.

[0039] Reference Figure 2 Several reinforcing rods 42 are fixed at the central axis along the length of the reinforcing plate 4. The reinforcing rods 42 are staggered and are made of PPS material, which has the characteristics of high temperature resistance, high rigidity, and high insulation. They are also low in cost, which helps to improve the firmness of both ends of the reinforcing plate 4 along the length, reduce the chance of the reinforcing plate 4 breaking, and improve its service life.

[0040] The implementation principle of a high-temperature resistant damping pad according to an embodiment of this application is as follows: The operator places the reinforcing plate 4 and the damping plate 2 facing each other, so that the connecting post 411-1 and the connecting post 412 are engaged. At this time, the buffer rings 53 on the circumference of the connecting post 411-1 and the connecting post 412 are squeezed together. The buffer holes 531 on different buffer rings 53 are squeezed to different degrees, which improves the adaptability of the buffer rings 53 to different gap sizes. At the same time, the reinforcing plate 4 and the damping plate 2 are bonded together with special adhesive. Then, the damping plate 2 is bonded to one side of the base plate 1, and the high-temperature resistant cloth 23 is bonded to the other side of the base plate 1. Finally, the base plate 1 is placed at the connection point of the vehicle, with the side with the high-temperature resistant plate placed at the connection point of the vehicle, and the bolts are screwed into all the mounting holes 11 to complete the installation.

[0041] During vehicle use, the generated impact force preferentially compresses the elastic connecting post 411 and connecting post 412, partially buffering the impact force through compression deformation. Subsequently, the compression slider 51 slides within the groove 413, causing the slider 51 to compress the buffer spring 52, resulting in the deformation of the buffer spring 52. The buffer spring 52 converts the deformation potential energy into elastic potential energy, thereby further buffering the impact force.

[0042] During the use of the shock-absorbing pad, the reinforcing rod 42 strengthens the reinforcing plate 4 along its length, which has a large difference in length and width, reducing the possibility of breakage. At the same time, the high-temperature resistant cloth 23 improves the high-temperature resistance of the shock-absorbing pad, thereby increasing its service life.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
