Description
Technical Field
[0001] This utility model relates to the field of shock absorption equipment, specifically to a cooling water pipe with shock absorption function. Background Technology
[0002] During the operation of a car's power system, a large amount of heat is generated due to fuel combustion and mechanical friction. If the heat cannot be dissipated in time, it will directly lead to the operating temperature of the components exceeding the standard, causing serious problems such as reduced power, increased fuel consumption, and even damage to core components. As a key carrier for the circulating heat dissipation of the power system, the cooling water pipe undertakes the core functions of transporting coolant and realizing heat exchange. Its stable operation directly determines the overall reliability and safety of the car.
[0003] In the automotive assembly process, cooling water pipes need to pass through pre-set holes in multiple metal structures such as the vehicle frame, engine block, and transmission housing, according to the overall vehicle layout. Although these metal holes have undergone basic processing, there may still be minor burrs or sharp edges on the hole walls. In addition, the metal material itself has high hardness and rigidity, and the contact interface with the cooling water pipe lacks buffer space. Currently, cooling water pipes are mostly made of elastic polymer materials such as rubber and EPDM (ethylene propylene diene monomer rubber). Although these materials have good corrosion resistance and flexibility, they are prone to wear when in direct contact with metal holes. Therefore, a cooling water pipe with shock absorption function has been proposed. Utility Model Content
[0004] In order to solve the technical problems existing in the prior art, the present invention provides a cooling water pipe with shock absorption function.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cooling water pipe with shock absorption function, including an outer connecting ring, a concentric inner sleeve ring is provided inside the outer connecting ring, a plurality of arc-shaped shock-absorbing rings connected to the outer connecting ring are provided outside the inner sleeve ring, and a fixing bolt is provided at the joint between the arc-shaped shock-absorbing ring and the outer connecting ring, the fixing bolt fixing the joint between the arc-shaped shock-absorbing ring and the outer connecting ring.
[0006] Preferably, the inner collar includes a collar body and an inner padding layer. The collar body has the same width as the outer connecting ring. The inner padding layer is glued to the inner wall of the collar body, and the external cooling water pipe passes through the inner padding layer.
[0007] Preferably, the arc-shaped shock-absorbing ring includes a shock-absorbing ring body and a connecting seat. Several sets of the shock-absorbing ring bodies are formed at equal intervals on the outside of the collar body, and the connecting seat is formed on the end of the shock-absorbing ring body. A screw hole is opened at the center of the connecting seat.
[0008] Preferably, the outer connecting ring has several sets of connecting notches inside that mate with the connecting seat, the connecting seat is nested in the notches, and each set of notches has a through hole for mate with the screw hole, and the fixing bolt is disposed in the through hole.
[0009] Preferably, the inner padding layer is made of heat-resistant EPDM material, and the thickness of the inner padding layer is 1.5-3mm.
[0010] Preferably, the inner wall of the inner padding layer is integrally formed with a plurality of anti-slip ridges extending along its axial direction, the cross-section of the anti-slip ridges is semi-circular, and the distance between two adjacent anti-slip ridges is 5-8mm.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model constructs a dual protection of physical isolation and elastic buffer by combining an inner sleeve ring and an arc-shaped shock-absorbing ring. The inner padding layer of the inner sleeve ring is directly attached to the external cooling water pipe. Its temperature-resistant EPDM material is soft and has anti-slip textures, which can not only avoid rigid friction between the water pipe and the main body of the sleeve ring, but also embed into the outer wall of the water pipe through the textures to prevent secondary friction caused by the relative sliding of the two during vibration. The arc-shaped shock-absorbing ring connects the inner sleeve ring and the outer connecting ring, so that when the outer connecting ring is fixed to the metal parts of the car, the inner sleeve ring and the cooling water pipe are completely separated from direct contact with the holes of the metal parts. The rigid friction relationship between the traditional water pipe and the metal parts is transformed into an elastic contact relationship between the water pipe, the inner padding layer and the arc-shaped shock-absorbing ring, eliminating the scratching and wear of the water pipe by the edge of the metal parts.
[0013] 2. In this utility model, the inner wall of the inner pad layer is completely fitted with the outer wall of the water pipe without gaps. The inner wall of the inner pad layer is integrally formed with several anti-slip ridges extending along its axial direction. The cross-section of the anti-slip ridges is semi-circular. The inner pad layer can buffer the radial force of water pipe vibration, further reducing the water pipe breakage rate. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0021] Example:
[0022] like Figures 1-4 As shown, a cooling water pipe with shock absorption function includes an outer connecting ring 1, which is made of 304 stainless steel and is used to fix the entire assembly with automotive metal parts.
[0023] The outer connecting ring 1 has a concentric inner ring 2 inside, the outer diameter of which matches the inner diameter of the outer connecting ring 1. The inner ring 2 includes a ring body 21 and an inner padding layer 22. The inner padding layer 22 is glued to the inner wall of the ring body 21, and the external cooling water pipe passes through the inner padding layer 22. The ring body 21 is made of modified PP material, which combines rigidity and toughness and can withstand 100N. Radial pressure does not deform, ensuring alignment with the outer connecting ring 1 during assembly. The inner pad 22 is made of heat-resistant EPDM with a thickness of 1.5-3mm. It is bonded to the inner wall of the collar body 21 with environmentally friendly acrylic adhesive to ensure a stable connection. When the external cooling water pipe passes through the inner pad 22, the inner wall of the inner pad 22 is completely fitted with the outer wall of the water pipe without gaps. The inner wall of the inner pad 22 is integrally formed with several anti-slip ridges extending along its axial direction. The cross-section of the anti-slip ridges is semi-circular, and the distance between two adjacent anti-slip ridges is 5-8mm. During use, the collar body 21 provides support, while the inner pad 22 buffers the radial force of water pipe vibration, further reducing the water pipe breakage rate.
[0024] The inner ring 2 is provided with several sets of arc-shaped shock-absorbing rings 3 connected to the outer connecting ring 1. There are a total of 4 sets of arc-shaped shock-absorbing rings 3, which are distributed at equal intervals along the outer peripheral wall of the inner ring 2. The two ends are tightly fitted to the outer wall of the inner ring 2 and the inner wall of the outer connecting ring 1 respectively to form an elastic connection. The arc-shaped shock-absorbing ring 3 is composed of a shock-absorbing ring body 31 and a connecting seat 32. The shock-absorbing ring body 31 is formed at equal intervals on the outside of the ring body 21, and the connecting seat 32 is formed at the end of the shock-absorbing ring body 31. A screw hole is opened at the center of the connecting seat 32. The vibration from the outer connecting ring 1 is transmitted to the shock-absorbing ring body 31 through the connecting seat 32. The shock-absorbing ring body 31 consumes the vibration energy by repeated deformation, thereby reducing the energy transmitted to the inner ring 2.
[0025] A fixing bolt 4 is provided at the junction of the arc-shaped shock-absorbing ring 3 and the outer connecting ring 1. The outer connecting ring 1 has several sets of connection notches that mate with the connecting seat 32. The connecting seat 32 is nested in the notches. Each set of notches has a through hole for mate with the screw hole. The fixing bolt 4 is set in the through hole. The fixing bolt 4 fixes the junction of the arc-shaped shock-absorbing ring 3 and the outer connecting ring 1. The fixing bolt 4 is an M5 stainless steel hexagonal bolt. After passing through the through hole of the outer connecting ring 1, it mates with the screw hole of the connecting seat 32 of the arc-shaped shock-absorbing ring 3.
[0026] The direct rigid contact between the cooling water pipe and the metal parts is transformed into an indirect elastic contact. The arc-shaped damping ring 3 can absorb low-frequency and high-frequency vibrations, while avoiding direct friction between the metal parts and the water pipe, greatly reducing vibration and impact, and extending the service life of the water pipe.
[0027] In use: Slide the inner ring 2 onto the outside of the cooling pipe. After the cooling pipe is installed in place, connect the inner ring 2 to the outer connecting ring 1. When connecting, the connecting seat 32 connects to the connecting notch opened inside the outer connecting ring 1. Connect the arc-shaped shock-absorbing ring 3 to the outer connecting ring 1 with the fixing bolt 4. Finally, install the outer connecting ring 1 into the hole on the automotive part.
[0028] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this utility model, all of which will fall within the protection scope of this utility model.
