Technical Field
[0001] This utility model relates to a suspension bracket assembly for a cooling water pump in a new energy vehicle. Background Technology
[0002] The cooling water pump is a core component of the cooling system in new energy vehicles, and its working condition directly affects the vehicle's heat dissipation and operational stability. Currently, cooling water pumps in new energy vehicles are typically directly fixed to the vehicle body or chassis using brackets. This fixing method has several drawbacks: Firstly, the cooling water pump generates low-frequency vibrations during operation, which can be easily transmitted directly to the vehicle body through the brackets, resulting in low-frequency noise and affecting driving comfort. Secondly, traditional brackets often employ a side-mounted disassembly structure, making disassembly and assembly cumbersome and time-consuming when repairing or replacing the cooling water pump, thus reducing maintenance efficiency.
[0003] In addition, for range-extended new energy vehicles, there is an exhaust pipe in the chassis. The large amount of heat generated when the exhaust pipe is working can easily be transferred to the cooling water pump. The long-term high temperature environment will accelerate the aging of the internal components of the cooling water pump and shorten its service life. At the same time, the noise generated when the cooling water pump is working will also be transmitted into the car through the gaps in the body, further affecting the driving experience.
[0004] There is a lack of a cooling water pump mounting bracket that can simultaneously achieve vibration reduction, sound insulation, heat insulation, and easy disassembly and assembly. Therefore, there is an urgent need to design a new type of bracket assembly to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a suspension bracket assembly for a new energy vehicle cooling water pump that achieves multiple effects such as shock absorption, sound insulation and heat insulation, while simplifying disassembly and assembly operations and improving maintenance convenience.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A suspension bracket assembly for a cooling water pump in a new energy vehicle includes:
[0008] A connecting plate, with bolt holes for connecting the vehicle body provided on the connecting plate;
[0009] An isolation cover, fixed to the bottom of the connecting plate, is used to cover the outside of the cooling water pump to isolate operating noise and vehicle body heat.
[0010] A vibration damping mounting structure is fixed to the bottom of the connecting plate and located inside the isolation cover, for fixing the cooling water pump.
[0011] Preferably, the insulation cover includes heat-insulating tiles and sound-insulating cotton, with the sound-insulating cotton fixed to the inner side of the heat-insulating tiles.
[0012] Preferably, two connecting posts are provided at the bottom of the connecting plate. The connecting posts pass through the heat insulation tile and the sound insulation cotton. Nuts are installed on the connecting posts, and the sound insulation cotton is screwed on the nuts to fix it.
[0013] Preferably, a rubber compression washer is fitted onto the connecting post, and the compression washer is located between the sound insulation cotton and the nut.
[0014] Preferably, the shock-absorbing mounting structure includes an upper clamp and a lower clamp; the upper clamp has first ear plates on both sides, and a vertical through-hole is provided on the surface of the first ear plate. A rubber bushing is fitted through the mounting hole, and an annular groove that fits the mounting hole is provided on the outer wall of the rubber bushing. A locking screw is screwed into the rubber bushing, and the locking screw passes through the rubber bushing and is screwed into the connecting column to fix the first ear plate. An internal threaded hole is also provided on the surface of the first ear plate. The lower clamp has second ear plates on both sides, and a through hole coaxial with the internal threaded hole is provided on the surface of the second ear plate. A tightening screw passes through the through hole. The tightening screw has a smooth rod portion and a threaded portion. The diameter of the smooth rod portion is larger than the diameter of the threaded portion. The smooth rod portion fits into the through hole, and the threaded portion is screwed into the internal threaded hole.
[0015] Preferably, a preload spring is coaxially positioned through the optical rod portion, and the preload spring acts between the first ear plate and the second ear plate.
[0016] Preferably, grooves are provided on the opposite surfaces of the upper and lower clamps, and a shock-absorbing ring made of elastic rubber is fixed through the grooves. The installed cooling water pump is interference-fitted into the shock-absorbing ring.
[0017] Preferably, anti-slip grooves are distributed in a ring on the inner wall of the shock-absorbing ring.
[0018] The beneficial effects of this utility model are:
[0019] 1. Dual vibration damping for significant noise reduction: This invention achieves first-level vibration damping of the cooling water pump through a damping ring, and then achieves second-level vibration damping through a rubber bushing. The dual vibration damping structure can effectively absorb the low-frequency vibration generated when the cooling water pump is working, and prevent the vibration from being transmitted to the vehicle body through the bracket, thus greatly reducing the probability of low-frequency noise in the vehicle and improving driving comfort.
[0020] 2. Sound and heat insulation to protect the water pump: The insulation cover is composed of heat insulation tiles and sound insulation cotton. The heat insulation tiles can effectively isolate the heat generated by the heat-generating parts of the vehicle body (such as the exhaust pipe of the range extender vehicle), avoid the high temperature from accelerating the aging of the internal parts of the cooling water pump, and extend the service life of the cooling water pump; the sound insulation cotton can absorb the noise generated when the cooling water pump is working, reduce the noise transmission to the outside world, and further improve the noise reduction effect.
[0021] 3. Easy disassembly and assembly, and efficient maintenance: The shock absorption installation structure adopts a vertical disassembly and assembly method. The upper and lower clamps are fixed by tightening screws. During maintenance, simply unscrew the tightening screws to remove the lower clamp and then take out the cooling water pump. Compared with the traditional side disassembly and assembly structure, the operation is simpler and faster, which greatly improves maintenance efficiency.
[0022] 4. Stable and reliable: The isolation cover is firmly fixed by the cooperation of nuts and compression washers; the pre-tightening spring reduces the chance of loosening of the tightening screws; the cooling water pump and the shock-absorbing ring are interference fit and the inner wall of the shock-absorbing ring is provided with anti-slip grooves to prevent the cooling water pump from shifting. The multiple structural designs ensure the installation stability and reliability of the entire bracket assembly. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] See Figure 1 , Figure 2 and Figure 3 The suspended bracket assembly of a cooling water pump for a new energy vehicle shown includes:
[0033] Connecting plate 1, with bolt holes 111 for connecting the vehicle body provided on the connecting plate 1;
[0034] Isolation cover 2, which is fixed to the bottom of the connecting plate 1, is used to cover the outside of the cooling water pump to isolate the working noise of the cooling water pump and the heat of the vehicle body heating components.
[0035] The vibration damping mounting structure 3 is fixed to the bottom of the connecting plate 1 and located inside the isolation cover 2, and is used to fix the cooling water pump.
[0036] In the above technical solution, the low-frequency vibration of the cooling water pump during operation is absorbed by the vibration damping installation structure 3, which prevents the low-frequency vibration from being transmitted to the vehicle and reduces the probability of low-frequency noise in the vehicle.
[0037] Secondly, the shock-absorbing installation structure 3 is vertically disassembled, which is easier to disassemble than the traditional lateral disassembly.
[0038] See Figure 1As shown, the insulation cover 2 includes heat insulation tiles 21 and sound insulation cotton 22, and the sound insulation cotton 22 is fixed to the inside of the heat insulation tiles 21 by fasteners.
[0039] In the above technical solution, the heat insulation tile 21 serves as external heat insulation, mainly for vehicles installed in range-extended vehicles. When there is an exhaust demand, the exhaust pipe will pass through the chassis to insulate the exhaust heat and protect the cooling water pump.
[0040] See Figure 1 and Figure 3 As shown, two connecting posts 11 are provided at the bottom of the connecting plate 1. The connecting posts 11 pass through the heat insulation tile 21 and the sound insulation cotton 22. Nuts 12 are installed on the connecting posts 11, and the sound insulation cotton 22 is screwed on the nuts 12 to fix it.
[0041] A rubber compression washer 13 is fitted onto the connecting post 11, and the compression washer 13 is located between the sound insulation cotton 22 and the nut 12.
[0042] In the above technical solution, the heat insulation tile 21 and the sound insulation cotton 22 can be fixed by the cooperation of the nut 12 and the clamping washer 13.
[0043] See Figure 1 and Figure 3 As shown, the shock-absorbing mounting structure 3 includes an upper clamp 31 and a lower clamp 32; the upper clamp 31 has a first ear plate 311 on both sides, and a vertical through mounting hole 312 is provided on the surface of the first ear plate 311. A rubber bushing 313 is clamped through the mounting hole 312. The outer wall of the rubber bushing 313 is provided with an annular groove (not shown) that fits the mounting hole 312. A locking screw 314 is screwed into the rubber bushing 313. The locking screw 314 passes through the rubber bushing 313 and is screwed into the connecting post 11 to fix the first ear plate 311. The lower end of the connecting post 11 is inserted into the rubber bushing 313. An internal threaded hole 315 is provided on the surface of the first ear plate 311. A second ear plate 321 is provided on both sides of the lower clamp 32. A through hole 322 coaxial with the internal threaded hole 315 is provided on the surface of the second ear plate 321. A tightening screw 323 passes through the through hole 322. The tightening screw 323 has a smooth rod portion 324 and a threaded portion 325. The diameter of the smooth rod portion 324 is larger than the diameter of the threaded portion 325. The smooth rod portion 324 fits into the through hole 322, and the threaded portion 325 is screwed into the internal threaded hole 315.
[0044] In the above technical solution, the vibration of the cooling water pump during operation can be absorbed by the rubber bushing 313, preventing the vibration from being transmitted to the vehicle body through the connecting column 11 and the connecting plate 1.
[0045] With the installation method using tightening screw 323, when maintenance is required on the cooling water pump, simply remove the tightening screw 323 to remove the clamp 32, and the entire cooling water pump can be removed.
[0046] See Figure 3 As shown, a preload spring 326 is coaxially positioned through the light rod portion 324, and the preload spring 326 acts between the first ear plate 311 and the second ear plate 321.
[0047] In the above technical solution, the pre-tensioning spring 326 can play a pre-tensioning role, further reducing the chance of loosening the tightening screw 323.
[0048] See Figure 3 As shown, grooves (not shown) are provided on the opposite surfaces of the upper clamp 31 and the lower clamp 32, and a shock-absorbing ring 4 made of elastic rubber is fixed through the grooves. The installed cooling water pump is interference-fitted into the shock-absorbing ring 4.
[0049] Anti-slip grooves 41 are distributed in a ring on the inner wall of the shock-absorbing ring 4.
[0050] The anti-slip groove 41 not only serves to prevent slipping, but also allows for the filling of adhesive into parts of the anti-slip groove 41 to glue and fix the shock-absorbing ring 4 to the housing of the cooling water pump.
[0051] In the above technical solution, the cooling water pump is first damped by the setting of the damping ring 4, and then a second damping is achieved by the rubber bushing. Under the double damping effect, the vibration of the cooling water pump during operation can be prevented from being transmitted to the vehicle body.
