Description

Technical Field

[0001] The invention relates to automobile parts, in particular to a fully limited radiator suspension cushion. Background Art

[0002] The existing radiator suspension pad product structure is bulky and cannot be installed effectively. The product's modal distribution is in the range of 34 to 100 Hz, which is completely coupled with the normal driving and total speed ignition modes of the engine, posing a risk of NVH problems. At the same time, the product's limiting structure is too complex and cannot be implemented industrially.

[0003] NVH is an abbreviation of three words: noise, vibration, and harshness (also commonly understood as harshness). Because these three components occur simultaneously and are inextricably linked in mechanical vibrations, such as those experienced by vehicles, they are often studied together. Simply put, all tactile and auditory sensations experienced by passengers in a vehicle fall within the scope of NVH research. This also includes issues such as the strength and lifespan of automotive components caused by vibration.

[0004] Application number: 201520297322.7 A car radiator suspension mounting structure can overcome the problems of radiator suspension eccentric wear and bracket bushing disengagement under extremely harsh road conditions.

[0005] Application number: 2014203271458. A radiator mounting device and vehicle are disclosed. This device completely isolates the radiator and cooling fan from the vehicle body, preventing bidirectional vibration transmission, cushioning impacts, and improving vehicle vibration and interior noise. Furthermore, the device simplifies the installation and removal of the radiator and electronic fan, facilitating installation and maintenance.

[0006] The product modal distribution in the above two patent documents is also in the range of 34~100Hz, and there is also a risk of NVH problems. Summary of the Invention

[0007] In order to make the product modal distribution less than 32Hz and solve the risk of NVH problems, the present invention specially proposes a fully limited radiator suspension pad.

[0008] To this end, the technical solution of the present invention is a fully limited radiator suspension cushion, comprising a lower bracket, the lower bracket being arranged horizontally, and characterized in that: a first protrusion is provided upwardly in the middle of the lower bracket, lower side brackets are provided on the upper surfaces of both sides of the lower bracket, the lower side brackets are arranged opposite to each other on both sides of the lower bracket to form an "eight"-shaped structure, and bolts are provided downwardly on both sides of the lower bracket;

[0009] The lower bracket is provided with an upper bracket corresponding to the lower bracket, the middle of the upper bracket is provided with a depression downward, and the middle of both sides of the upper bracket are provided with a second protrusion upward, and the depression and the second protrusion form an "M"-shaped structure of the upper bracket; wherein the middle of the "M"-shaped structure formed by the second protrusion is provided with a through nut;

[0010] A first rubber body is provided on the upper surface of the lower bracket, wherein the two inner surfaces of the "M"-shaped structure of the upper bracket and the first rubber body on the "eight"-shaped lower bracket are correspondingly bonded together;

[0011] The first protrusion of the lower bracket and the recess of the upper bracket are fastened together by snap fasteners.

[0012] The bolt and the through nut are on the same axis.

[0013] In the present invention, the lower bracket and the upper bracket form a corresponding relationship. At the same time, the "eight"-shaped structure formed by the lower bracket supports the "M"-shaped upper bracket through the first rubber body, so that the upper bracket does not displace to achieve the purpose of vibration reduction. At the same time, the first protrusion of the lower bracket and the depression of the upper bracket are fastened together by buckles to form an organic whole, and they coordinate with each other to make their modal distribution within 32Hz, and the modal distribution interval is ≥2Hz.

[0014] A further improvement is that the first rubber body vulcanizes the two inner surfaces of the "M"-shaped structure of the lower bracket and the upper bracket together.

[0015] After adopting overall vulcanization, the industrial production efficiency of the product is improved.

[0016] A further improvement is that a second rubber body is vulcanized on both surfaces of the recess of the upper bracket.

[0017] The second rubber body is provided so that the first upward protrusion in the middle of the lower bracket and the downward depression in the middle of the upper bracket are fastened together through buckles to achieve the purpose of coordinated vibration; and the six degrees of freedom of the radiator suspension cushion, namely front, back, left, right, up and down, are upper limited.

[0018] A further improvement is that the lower side brackets are welded to the upper surfaces of both sides of the lower bracket.

[0019] Sheet metal stamping and sheet metal welding processes reduce product costs and achieve product lightweighting.

[0020] A further improvement is that the first rubber body and the second rubber body are made of EPDM material.

[0021] This makes it better than natural rubber in terms of heat resistance, oil resistance and ozone resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention Figure 1-3 shown.

[0030] A fully limited radiator suspension cushion includes a lower bracket 31, which is arranged horizontally. A first protrusion 32 is provided upward in the middle of the lower bracket 31, and lower side brackets 33 are provided on the upper surfaces of both sides of the lower bracket 31. The lower side brackets 33 are arranged on both sides of the lower bracket 31 to form an "eight" structure. Bolts 34 are also provided on both sides of the lower bracket 31.

[0031] The lower bracket 31 is provided with an upper bracket 41 correspondingly. A recess 42 is provided downwardly in the middle of the upper bracket 41. Second protrusions 43 are provided upwardly in the middle of both sides of the upper bracket 41. The recess 42 and the second protrusion 43 form an "M"-shaped structure of the upper bracket 41. A through nut 44 is provided in the middle of the "M"-shaped structure formed by the second protrusion 43.

[0032] A first rubber body 35 is provided on the upper surface of the lower bracket 33, wherein the two inner surfaces of the "M"-shaped structure of the upper bracket 41 and the first rubber body 35 on the "eight"-shaped lower bracket 33 are correspondingly bonded together;

[0033] The first protrusion 32 of the lower bracket 31 and the recess 42 of the upper bracket 41 are fastened together by a buckle 51 .

[0034] The bolt and the through nut are on the same axis.

[0035] In the present invention, the lower bracket 31 and the upper bracket 41 form a corresponding relationship. At the same time, the "eight"-shaped structure formed by the lower bracket 33 supports the "M"-shaped upper bracket 41 through the first rubber body 35, so that the upper bracket 41 does not displace to achieve the purpose of vibration reduction. At the same time, the first protrusion 32 of the lower bracket 31 and the recess 42 of the upper bracket 41 are fastened together by the buckle 51 to form an organic whole, and they coordinate with each other to make their modal distribution within 32Hz, and the modal distribution interval ≥2Hz.

[0036] The first rubber body 35 vulcanizes the two inner surfaces of the "M"-shaped structure of the lower bracket 33 and the upper bracket 41 together.

[0037] After adopting overall vulcanization, the industrial production efficiency of the product is improved.

[0038] A second rubber body 45 is vulcanized on both surfaces of the recess 42 of the upper bracket 41 .

[0039] The arrangement of the second rubber body 45 enables the upward first protrusion 32 in the middle of the lower bracket 31 and the downward recess 42 in the middle of the upper bracket 41 to be fastened together through the buckle 51 to achieve the purpose of coordinated vibration; and realizes the upper limit of the six degrees of freedom of the radiator suspension cushion: front, back, left, right, up and down.

[0040] The lower brackets 33 are welded to the upper surfaces of both sides of the lower bracket 31 .

[0041] Sheet metal stamping and sheet metal welding processes reduce product costs and achieve product lightweighting.

[0042] The first rubber body 35 and the second rubber body 45 are made of EPDM material.

[0043] This makes it better than natural rubber in terms of heat resistance, oil resistance and ozone resistance.

[0044] Finally, the fully limited radiator suspension pad 3 is connected to the radiator pad bracket 2 on the radiator assembly 1 to complete the assembly process.
