Abstract
Description
A pad for automotive radiators with a shock-absorbing structure Technical Field
[0001] This utility model relates to the field of automotive radiator technology, specifically to a pad for automotive radiators with a shock-absorbing structure. Background Technology
[0002] As a core component of the cooling circuit, the automotive radiator plays a crucial role in transferring engine heat to the outside environment through coolant-air heat exchange. The wide-frequency vibrations generated during engine operation, combined with random vibration loads from road impacts during vehicle travel, can easily lead to radiator weld cracking, fin plastic deformation, and leaks at the inlet and outlet water pipe interfaces over long-term exposure. Radiator spacers, as vibration isolation devices, have emerged to address this issue. Typically, radiator spacers are inserted into support holes in the front frame of the vehicle, abutting against the lower end of the radiator. This component is usually molded from rubber material. However, there is a trade-off between the hardness, vibration isolation efficiency, and service life of rubber. If the rubber material is too hard, high-frequency vibrations can cause fatigue and breakage of the spacer. If the rubber material is too hard, the spacer's stability is insufficient, resulting in a poor fit between the spacer and the radiator fins, which can easily damage the radiator fins during manufacturing.

[0012] (III) Beneficial Effects
[0013] This utility model provides a pad for an automotive radiator with a shock-absorbing structure. It has the following beneficial effects:
[0014] 1. In this utility model, the rubber pad body is inserted into the support hole of the front frame of the car. The positioning collar is engaged with the upper edge of the support hole of the front frame of the car to form a positioning, so that the connecting ring supports the bottom of the rubber pad body and the elastic bow plate. The radiator presses down on the upper side of the pressing part of the rubber pad body. The pressing part squeezes the elastic bow plate, causing the elastic bow plate to deform outward. This tightly squeezes the sleeve part of the rubber pad body onto the inner wall of the support hole of the front frame of the car to form a fixation. At the same time, the reaction force of the elastic bow plate provides buffer elasticity for the rubber pad body, which can play a shock absorption role for the car radiator.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model embodiment provides a car radiator pad with a shock-absorbing structure for installation in the support hole of the front frame of a car, as shown in Figures 1-4. It includes a rubber pad body 1, which includes an integrally formed pressing part 101 and a sleeve part 102. The outer diameter of the sleeve part 102 is slightly smaller than or equal to the inner diameter of the support hole of the front frame of the car. The sleeve part 102 passes through the support hole of the front frame of the car. The lower edge of the pressing part 101 abuts against the upper edge of the support hole of the front frame of the car. An installation cavity is formed inside the sleeve part 102. A plurality of vertical grooves 2 are formed on the outer wall of the sleeve part 102 at intervals. The vertical grooves 2 evenly divide the sleeve part 102 into a plurality of deformable parts.
[0022] As shown in Figures 2-3, a skeleton mechanism is fixed inside the mounting cavity. The skeleton mechanism includes a pressing plate 5, a positioning frame 6, and several elastic arch plates 7. The lower side of the pressing part 101 is bonded and fixed to the upper side of the pressing plate 5. The positioning frame 6 includes a positioning collar 61, a connecting ring plate 62, and several connecting beams 63. The positioning collar 61 is sleeved on the outer wall of the sleeve part 102. A fitting ring groove 3 is provided on the lower side of the pressing part 101. The positioning collar 61 is fitted and inserted into the fitting ring groove 3, allowing the positioning collar 61 to be hidden in the fitting ring groove 3. An assembly groove 4 is provided at the lower end of the sleeve part 102. The connecting ring plate 62 is inserted and inserted into the assembly groove 4. The connecting ring plate 62 covers... The system includes an inner connecting ring 621, an outer connecting ring 622, and a spacer block 623 fixed between the inner connecting ring 621 and the outer connecting ring 622. The inner edge of the inner connecting ring 621 extends into the mounting cavity. The upper and lower ends of the elastic arch plate 7 are respectively fixedly connected between the pressing plate 5 and the inner connecting ring 621. The elastic arch plate 7 is configured as an elastic plate with a central outward protrusion. The elastic arch plate 7 is in concave-convex fit against the inner wall of the mounting cavity. The upper and lower ends of the connecting beam 63 are respectively connected between the positioning collar 61 and the outer connecting ring 622. The connecting beam 63 is in concave-convex fit inserted into the vertical groove 2. The elastic arch plate 7 and the connecting beam 63 are staggered. The elastic arch plate 7 is in contact with the corresponding deformation part of the inner wall of the rubber pad body 1.
[0023] Working principle:
[0024] In this invention, a pad for the car radiator can be inserted into the support hole of the front frame of the car. Since the outer diameter of the sleeve 102 is slightly smaller than or equal to the inner diameter of the support hole of the front frame of the car, the rubber pad body 1 can be smoothly inserted into the support hole, avoiding jamming and installation difficulties. The positioning collar 61 overlaps and abuts against the outer edge of the support hole to form a fixation, so that the positioning frame 6 is fixed relative to the front frame of the car. When the car radiator is placed on the rubber pad body 1, the weight of the radiator body 1 will squeeze the pressing piece 5 downward and compress the elastic bow piece 7 to deform outward. The deformed part of the rubber pad body 1 that abuts and compresses expands towards the inner wall of the support hole, forming a lock, which can fix the rubber pad body 1 in the support hole. The reaction force of the elastic bow piece 7 acts on the pressing piece 5, which can provide shock absorption and cushioning for the car radiator.
