Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, specifically to an engine water pipe shock-absorbing and buffering mounting bracket. Background Technology
[0002] Engine water hoses are a crucial component of the engine cooling system, responsible for circulating and delivering coolant. Due to the continuous and intense vibrations generated by the engine during operation, the water hoses will vibrate and shift accordingly. Traditional mounting brackets often use metal clips or rigid plastic brackets to directly clamp the water hoses. This rigid connection method has the following drawbacks: First, it cannot effectively absorb and buffer vibrations transmitted from the engine, easily leading to wear and even breakage at the contact points between the water hose and the bracket due to long-term friction; second, the direct transmission of vibration exacerbates stress concentration at the water hose joints, easily causing loosening of the joints and coolant leakage; third, continuous vibration and abnormal noises can also affect the overall NVH (noise, vibration, and harshness) performance of the vehicle.
[0003] To reduce the aforementioned adverse effects, existing technologies typically use brackets with cushioning pads to fix water pipes, achieving a shock-absorbing effect. However, since engine water pipes are non-standard parts, their shape is greatly affected by the engine's shape, and the pipe sizes used vary, existing fixed clamps with pads have poor adaptability during use.
[0004] Therefore, this application provides an engine water pipe shockproof buffer mounting bracket to solve the above problems. Utility Model Content
[0005] This application provides an engine water pipe shockproof buffer mounting bracket, which aims to solve the problems of poor adaptability of existing water pipe brackets mentioned in the background art.
[0006] To achieve the above objectives, this application provides the following technical solution: a shock-absorbing and buffering fixing bracket for engine water pipes, comprising a support portion for supporting the water pipes and a clamping portion detachably connected to the support portion and mounted on the support portion for clamping the water pipes.
[0007] The support part is provided with a lifting groove that is adapted to the pressing part, and the pressing part is inserted into the lifting groove;
[0008] The support portion has a first limiting groove for supporting the water pipe, which is formed through the lifting groove. The clamping portion has a second limiting groove for clamping the water pipe. The first limiting groove is U-shaped, and the second limiting groove is V-shaped. The open ends of the first and second limiting grooves are positioned opposite each other. A first buffer portion is provided in the first limiting groove to contact the outer wall of the water pipe, and a second buffer portion is provided in the second limiting groove to contact the outer wall of the water pipe. In use, the support portion is placed under the water pipe and connected to the engine mounting surface. Then, the water pipe is placed into the first limiting groove. Next, the second limiting groove on the clamping portion is aligned with the top of the water pipe and pressed down into the lifting groove. Depending on the diameter of the water pipe, the clamping portion moves up and down within the lifting groove, thereby changing the staggered position of the first and second limiting grooves to adapt to different water pipe profiles. The first and second buffer portions cushion the outer wall of the water pipe, improving the adaptability of the equipment.
[0009] Preferably, in order to protect the water pipe, the first buffer part includes a first mounting groove formed at the bottom of the first defined groove, and a first buffer pad is bonded and fixed in the first mounting groove to improve the protection effect on the water pipe.
[0010] Preferably, in order to protect the water pipe, the second buffer part includes a second mounting groove formed on the inner side wall of the second limiting groove, and a second buffer pad is bonded and fixed in the second mounting groove to improve the protection effect on the water pipe.
[0011] Preferably, in order to align the equipment, a guide groove is provided on the inner side wall of the lifting groove on the support part, and a guide rod adapted to the guide groove is fixedly installed on the outer side wall of the pressing part. The guide rod is slidably installed in the guide groove to ensure stable pressing and fixing of the water pipe.
[0012] Preferably, in order to ensure stability, a third mounting groove is provided on the outer wall of the support part, and a third buffer pad is bonded and fixed in the third mounting groove to improve the stability when the equipment is in contact with the engine mounting surface.
[0013] Preferably, for ease of installation, the support and clamping parts are provided with fixing holes, and fastening bolts are inserted into the fixing holes. A spring is fitted on the fastening bolt to abut against the outer wall of the support and clamping parts, which makes the adjustment of the fastening bolts more stable and reliable and avoids shaking.
[0014] The fixed bracket places the support part under the water pipe and connects it to the engine mounting surface. Then, the water pipe is placed into the first limiting groove, and the second limiting groove on the clamping part is aligned with the top of the water pipe and pressed down into the lifting groove. Depending on the diameter of the water pipe, the clamping part moves up and down in the lifting groove, thereby changing the staggered position of the first and second limiting grooves to adapt to different water pipe profiles. The first and second buffer parts cushion the outer wall of the water pipe, improving the adaptability of the equipment.
[0015] The mounting bracket is installed by aligning the support part with the pre-drilled holes on the engine mounting surface, then inserting the clamping part into the support part, clamping the water pipe, inserting the fastening bolt into the fixing hole, and connecting the support part and the clamping part to complete the installation of the equipment. During installation, the spring is placed between the support part and the clamping part, aligned with the two fixing holes, and then the fastening bolt is inserted so that the spring fits on the fastening bolt. This makes the adjustment of the fastening bolt more stable and reliable, and avoids shaking. Attached Figure Description

The first limiting groove 22 is U-shaped and the second limiting groove 31 is V-shaped. The opening ends of the first limiting groove 22 and the second limiting groove 31 are arranged opposite to each other. The first limiting groove 22 is provided with a first buffer part 23 that contacts the outer wall of the water pipe 1, and the second limiting groove 31 is provided with a second buffer part 32 that contacts the outer wall of the water pipe 1.
[0028] In use, the support part 2 is placed under the water pipe 1 and connected to the engine mounting surface. Then, the water pipe 1 is placed into the first limiting groove 22. Then, the second limiting groove 31 on the clamping part 3 is aligned with the top of the water pipe 1 and pressed down into the lifting groove 21. Depending on the diameter of the water pipe 1, the clamping part 3 is moved up and down in the lifting groove 21 to change the staggered position of the first limiting groove 22 and the second limiting groove 31, thereby adapting to different contours of the water pipe 1. The first buffer part 23 and the second buffer part 32 are used to cushion the outer wall of the water pipe 1, improving the adaptability of the equipment.
[0029] Specifically, the first buffer part 23 includes a first mounting groove 231 formed at the bottom of the first limiting groove 22, and a first buffer pad 232 is bonded and fixed in the first mounting groove 231.
