Description

Technical Field

[0001] This utility model relates to the field of automotive parts application technology, and in particular to a double-layer structure vehicle water tank shock-absorbing pad. Background Technology

[0002] A water tank damping pad (or water tank buffer pad) is a component used to fix and buffer the vibration of a car's water tank (radiator). Its main function is to reduce the impact of vibrations generated in the engine compartment due to vehicle driving or engine operation on the water tank, thereby extending the service life of the water tank and related pipes.

[0003] Existing automotive water tank shock absorber pads are generally integrated units, resulting in poor energy absorption under shock pressure and inability to meet the required shock absorption function. Furthermore, liquid can accumulate in the internal pores, causing damage to the shock absorber pad during prolonged immersion. Once damaged, the entire pad needs to be replaced, increasing replacement costs. Therefore, this utility model proposes a double-layer structure automotive water tank shock absorber pad. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-layer structure vehicle water tank shock absorber. By setting the entire shock absorber in double layers, the upper and lower rubber shock absorbers can work together to achieve efficient energy absorption, thereby ensuring the stability of the water tank. In addition, the double-layer splicing setting makes it convenient to replace part of it later, thereby reducing the cost of using the shock absorber.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a double-layer structure vehicle water tank shock absorber pad is provided, including a rubber base, a rubber top cover is threadedly connected to the top of the rubber base, a pressure spring is provided at the center of the inner top of the rubber top cover, and the bottom of the pressure spring is engaged with the center of the inner bottom of the rubber base.

[0006] The present invention is further configured such that: a plurality of extension blocks are uniformly fixedly connected to the outer wall of the rubber base near the bottom position, and the plurality of extension blocks are arranged in five equidistant positions.

[0007] The above technical solution ensures the stability of the rubber base position after placement by using multiple extension blocks.

[0008] The present invention is further configured such that: a central hole is provided at the center of the rubber base, and multiple drainage grooves are evenly provided at the bottom of the rubber base. The multiple drainage grooves are arranged in five groups, with two in each group. At the same time, each group of drainage grooves is arranged alternately with multiple extension blocks. The multiple drainage grooves converge at the central hole, and the end face away from the central hole extends to the outer wall of the rubber base.

[0009] The above technical solution uses multiple drainage channels to quickly disperse the liquid flowing out through the central hole to the surrounding area, preventing the liquid from remaining inside the rubber base for a long time and causing damage.

[0010] The present invention is further configured such that: a plurality of support blocks are uniformly fixedly connected in the circumferential direction at the inner bottom of the rubber base near the inner wall, a receiving sleeve is fixedly connected at the intersection of the plurality of support blocks, and the bottom of the pressure spring abuts against the inner bottom of the receiving sleeve.

[0011] The above technical solution utilizes the support block to perform energy absorption operation on the receiving sleeve within a certain space, thereby improving the overall shock absorption effect of the shock-absorbing pad and fixing the position of the bottom of the pressure spring.

[0012] The present invention is further configured such that: the outer diameter of the receiving sleeve is larger than the inner diameter of the central hole, and the bottom of the receiving sleeve is far away from the top of the central hole.

[0013] The above technical solution allows the receiving sleeve to be pressed forcefully, so that it can act on the rubber base, and the central hole can be used to clear the liquid that has entered the interior.

[0014] The present invention is further configured such that: the top of the rubber top cover is uniformly fixedly connected with a plurality of anti-slip protrusions; the outer wall of the rubber top cover is uniformly provided with a plurality of alternating energy-absorbing holes A and B in the circumferential direction; a fixing sleeve is fixedly connected to the center of the inner top of the rubber top cover; the inner top of the fixing sleeve abuts against the top of the pressure spring; and the outer wall of the fixing sleeve is uniformly fixedly connected with a plurality of reinforcing ribs in the circumferential direction; and the rubber top cover is threadedly connected to the inner wall of the rubber base through a threaded extension ring provided at its bottom near the inner wall.

[0015] The above technical solution allows for easy and stable installation of the rubber top cover on the rubber base using an extension sleeve, and the use of a fixing sleeve can fix the compression position of the pressure spring. Furthermore, the use of multiple protective protrusions can improve the stability between the pressure spring and the water tank.

[0016] The present invention is further configured such that all of the energy-absorbing holes A and B are arranged in an isosceles trapezoidal shape, and the adjacent energy-absorbing holes A and B are arranged in a staggered relative manner.

[0017] The above technical solution facilitates energy absorption through multiple energy-absorbing holes A and B when the rubber top cover is squeezed, thereby improving the overall shock absorption effect of the damping pad.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The present invention proposes a double-layer structure vehicle water tank shock absorber pad. By setting the entire shock absorber pad in two layers, the upper and lower rubber shock absorber pads can work together to achieve efficient energy absorption, thereby ensuring the stability of the water tank.

[0020] 2. The double-layer structure vehicle water tank shock absorber proposed in this utility model can be easily replaced later by splicing the double layers, thereby reducing the cost of using the shock absorber. Attached Figure Description

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] like Figures 1-3As shown, a double-layer structure vehicle water tank shock absorber includes a rubber base 1. Multiple extension blocks 11 are evenly and fixedly connected to the outer wall of the rubber base 1 near its bottom. Five extension blocks 11 are arranged at equal intervals to ensure the stability of the rubber base 1 after placement. A central hole 12 is provided at the center of the rubber base 1. Multiple drainage grooves 121 are evenly provided on the bottom of the rubber base 1, arranged in five groups of two. Each group of drainage grooves 121 is alternately arranged with the extension blocks 11. The drainage grooves 121 converge at the central hole 12 and extend to the outer wall of the rubber base 1 from the end face away from the central hole 12. The multiple drainage grooves 121 allow liquid flowing out through the central hole 12 to be quickly dispersed in all directions. To prevent liquid from stagnating inside the rubber base 1 for an extended period and causing damage, multiple support blocks 13 are evenly fixedly connected circumferentially at the inner bottom of the rubber base 1 near the inner wall. A receiving sleeve 14 is fixedly connected at the intersection of the multiple support blocks 13. The bottom of the pressure spring 3 is pressed against the inner bottom of the receiving sleeve 14. The support blocks 13 can perform a certain amount of energy absorption operation on the receiving sleeve 14, thereby improving the shock absorption effect of the entire shock-absorbing pad. At the same time, the position of the bottom of the pressure spring 3 is fixed. The outer diameter of the receiving sleeve 14 is larger than the inner diameter of the central hole 12, and the bottom of the receiving sleeve 14 is far away from the top of the central hole 12, so that when the receiving sleeve 14 is squeezed, it can act on the rubber base 1. The central hole 12 can be used to drain the liquid that has entered the interior.

[0027] like Figure 1 and Figure 2As shown, a rubber top cover 2 is threadedly connected to the top of the rubber base 1. A pressure spring 3 is installed at the center of the inner top of the rubber top cover 2, and the bottom of the pressure spring 3 is engaged with the center of the inner bottom of the rubber base 1. Multiple anti-slip protrusions 21 are evenly fixedly connected to the top of the rubber top cover 2. Multiple energy-absorbing holes A22 and B23 are evenly distributed in the circumferential direction at the middle of the outer wall of the rubber top cover 2. A fixing sleeve 24 is fixedly connected to the center of the inner top of the rubber top cover 2. The inner top of the fixing sleeve 24 abuts against the top of the pressure spring 3, and multiple reinforcing ribs 25 are evenly fixedly connected in the circumferential direction on the outer wall of the fixing sleeve 24. The rubber top cover 2 is secured by its bottom abutting against the pressure spring 3. A threaded extension ring 26, located near the inner wall, is threadedly connected to the inner wall of the rubber base 1. The threaded extension ring 26 allows for easy and stable installation of the rubber top cover 2 onto the rubber base 1. The fixing sleeve 24 secures the compression position of the pressure spring 3. Multiple anti-slip protrusions 21 enhance stability with the water tank. Multiple energy-absorbing holes A22 and B23 are arranged in isosceles trapezoidal shapes, and adjacent energy-absorbing holes A22 and B23 are staggered relative to each other. This allows the rubber top cover 2 to absorb energy through the multiple energy-absorbing holes A22 and B23 when compressed, thereby improving the overall shock absorption effect of the damping pad.

[0028] When this utility model is in use, when the vehicle water tank is vibrated, the resulting vibration impact force will act on the top of the rubber top cover 2, and under the action of multiple energy-absorbing holes A22 and B23, energy absorption will be performed in advance. At the same time, the force can be applied to the pressure spring 3 through the fixing sleeve 24, and then transmitted to the bottom receiving sleeve 14. The receiving sleeve 14 then transmits the force to the multiple support blocks 13 around it, thereby achieving a double-layer shock absorption operation and improving the operation of the vehicle water tank.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
