Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle design and manufacturing, and particularly relates to a controller integrating vibration isolation and heat dissipation. Background Art
[0002] With the development trend of vehicle transmission system integration, the controller and system hardware are continuously integrated, which is very likely to cause problems such as poor heat dissipation performance and unstable signal transmission caused by excessive vibration, which will inevitably seriously affect product reliability. As a key structure to ensure the stable operation of the transmission system, the controller assembly can greatly reduce the failure of the transmission system and improve product competitiveness through reasonable heat dissipation and vibration isolation design.
[0003] The temperature of the control panel components continues to rise, exceeds the tolerance temperature and burns out, which is a direct manifestation of poor heat dissipation of the controller assembly. The failure is mostly due to unreasonable assembly structure design, resulting in excessive thermal resistance of the heat transfer path, and the heat generated by the continuous operation of the components accumulates locally and forms local high temperatures, causing component damage. The signal transmission of the controller assembly is unstable. The cause is mostly unreasonable or no consideration of vibration isolation design when the control panel is integrated with the housing. The vibration signal of the whole vehicle is transmitted to the control panel with low loss, and the connection of some wiring ports of the control panel is affected. The signal transmission is unstable, resulting in sudden failure of the transmission system, affecting the customer experience.
[0004] Although there are many solutions available for reference in the heat dissipation or vibration isolation design of the controller assembly, most of them have complex structures, insufficient reliability, and it is difficult to meet both design requirements at the same time.

[0034] The utility model is further described in detail below with reference to the accompanying drawings:
[0035] The main purpose of the utility model is to design a structure with simple structure and strong reliability in order to meet the heat dissipation and vibration isolation requirements of the controller assembly at the same time. In view of the prominent problems of the complex structure, insufficient reliability and difficulty in meeting the vibration isolation and heat dissipation requirements in the existing technical solutions, a design solution that can meet the heat dissipation and vibration isolation requirements at the same time, with simple structure and strong reliability is proposed:
[0036] See also Figure 1A controller integrating vibration isolation and heat dissipation comprises a heat dissipation shell 1, a control board 4 is arranged on the upper surface of the heat dissipation shell 1, and heat-conducting gel 3 and rubber ring 2 are filled in sequence from the center to the surrounding between the heat dissipation shell 1 and the control board 4; the heat-conducting gel 3 is filled between the control board 4 and the heat dissipation shell 1, which can effectively transfer the heat generated by the heat-generating component 10 to the heat dissipation shell, and reasonably plan the heat transfer path from the control board 4 to the heat dissipation shell 1 to improve the heat dissipation capacity of the control board 4; at the same time, the characteristics of the gel and the rubber ring 2 arranged on the outer ring of the heat-conducting gel 3 for protecting and fixing the heat-conducting gel 3 can effectively block the vibration energy of the whole vehicle from being transmitted to the control board, and the simple structural design and ingenious layout conception reduce the risk of wiring falling off of the interface on the surface of the control board, and ensure the stability of signal transmission; it solves the prominent problems of complex structure, insufficient reliability, and difficulty in meeting the vibration isolation and heat dissipation requirements in the prior art.
[0037] In some embodiments, a heat generating component 10 is disposed on the control board 4, and the heat conductive gel 3 is filled in the corresponding area of the heat generating component 10 below the control board 4. The heat of the heat generating component of the control board 4 can be effectively transferred to the heat dissipation housing 1, and the vibration energy of the heat dissipation housing 1 can be reduced from being transferred to the control board 4.
[0038] In some embodiments, the controller integrating vibration isolation and heat dissipation further comprises a rubber ring 2, which is an annular structure and is arranged between the heat dissipation housing 1 and the control board 4. The thermal conductive gel 3 is located at the inner ring of the rubber ring 2. The rubber ring 2 is designed in detail, that is, the area directly opposite to the heating element (10) is filled with gel, and the other areas are rubber. The rubber ring 2 is customized for different control boards 4, which effectively reduces the amount of thermal conductive gel 3 used, has a simple structure, and reduces costs. In addition, the thickness of the thermal conductive gel 3 is not less than the thickness of the rubber ring 2, ensuring that the thermal conductive gel 3 is tightly fitted to the control board 4.
[0039] In some embodiments, a controller integrating vibration isolation and heat dissipation includes a heat dissipation shell 1, a rubber ring 2, a thermally conductive gel 3, a control board 4, a rubber pad 5, and a bolt 6. The heat dissipation shell 1 has a fin structure at the bottom, and is sequentially provided with the following at the top: a rubber ring 2, a thermally conductive gel 3, a control board 4, and a rubber pad 5, which are fixedly connected by bolts 6, so that the heat of the heat generating components of the control board 4 can be effectively transferred to the heat dissipation shell 1, and the vibration energy of the heat dissipation shell 1 can be reduced from being transferred to the control board 4. A threaded hole 9 is provided at the top of the heat dissipation shell 1, and the threaded hole 9 corresponds to a reserved through hole 7 of the control board 4. The rubber ring 2 is an annular structure, which is determined according to the size of the control board 4. The structure of the rubber ring 2 is fixed, and the rubber ring 2 has a through hole 8 corresponding to the threaded hole 9 one by one; the thermal conductive gel 3 is formed by solidifying the liquid gel, and is completely fitted around the rubber ring 2. The height of the thermal conductive gel 3 is slightly higher than the rubber ring 2, ensuring that the thermal conductive gel 3 is tightly fitted to the control board 4; the rubber pad 5 is annular, and can be divided into two identical structures along the diameter direction, with an "L"-shaped cross-section, and is placed at the control board through hole 7 reserved for the control board 4 to ensure that the bolt 6 does not have direct contact with the control board 4; the bolt 6 passes through the rubber pad 5, the control board through hole 7 reserved for the control board 4, and the through hole 8 formed in the rubber ring 2, and is fixedly connected to the threaded hole 9 above the heat dissipation housing 1.
[0040] In some embodiments, the rubber ring 2 is designed in detail according to the position and size of the heating element 10 on the surface of the control board 4, that is, the area directly opposite to the heating element 10 is filled with gel, and the other areas are filled with rubber, so that the rubber ring 2 can be customized for different control boards 4, effectively reducing the amount of thermal conductive gel 3, simplifying the structure, and reducing costs;
[0041] In some embodiments, when the controller is assembled, the bolt 6 is tightened, the bolt 6 is in close contact with the rubber ring 2 and the rubber pad 5, and the rubber ring 2 and the thermal conductive gel 3 between the heat dissipation housing 1 and the control board 4 are compressed;
[0042] In some embodiments, when the vehicle is running, the vibration energy transmitted from the vehicle to the heat dissipation housing 1 is effectively blocked by the rubber ring 2 and the thermal conductive gel 3, and then transmitted to the control board 4, and the signal transmission between the control board 4 and the socket interface 11 is more stable;
[0043] In some embodiments, the controller works continuously, and the heat generated by the heat-generating components 10 on the surface of the control board 4 is transferred to the heat dissipation housing 1 through the thermal conductive gel 3, and then the fins below the heat dissipation housing 1 convect with the outside air to effectively dissipate the heat, thereby building a complete and efficient heat transfer and heat dissipation path.
[0044] like Figure 1 , Figure 2As shown, a rubber ring 2, a thermal conductive gel 3, a control board 4, and a rubber pad 5 are sequentially arranged below the heat dissipation housing 1 and fixedly connected by bolts 6; the rubber ring 2, the thermal conductive gel 3, and the rubber pad 5 can prevent the control board 4 from directly and rigidly contacting the heat dissipation housing 1, and the thermal conductive gel 3 builds a heat transfer path between the heat generating components 10 on the surface of the control board 4 and the heat dissipation housing 1;
[0045] like Figure 3 , Figure 4 As shown, a rubber ring 2 is arranged above the heat dissipation housing 1. The rubber ring 2 is an annular structure, and its specific size is determined according to the control board 4. The rubber ring 2 is provided with a through hole 8 corresponding to the reserved through hole 7 of the control board 4, and the inner side is filled with a thermal conductive gel 3. Although rubber has a vibration isolation effect, it does not conduct heat. The thermal conductive gel 3 makes up for this defect. To ensure the maximum heat dissipation effect, the area filled with the thermal conductive gel 3 should completely cover the heat generating component 10, and completely fit with the boundary of the rubber ring 2. The heat generated by the heat generating component 10 can be efficiently transferred to the heat dissipation housing 1 through the thermal conductive gel 3, and the heat is dissipated through the fins above the housing and the air convection, thereby avoiding the heat accumulation caused by the poor heat dissipation of the heat generating component 10 of the control board.
[0046] like Figure 5 , Figure 6 As shown, the threaded holes 9 opened on the top of the heat dissipation shell 1 and the through holes 8 opened on the rubber ring 2 are consistent in number with the through holes 7 reserved in the control board 4; the inner diameters of the through holes 8 and the threaded holes 9 are slightly smaller than the inner diameter of the through holes 7, but consistent with the screw diameter of the bolt 6; the inner diameter of the rubber pad 5 is consistent with the screw diameter of the bolt 6, the outer diameter of the small end is consistent with the inner diameter of the through hole 7, the outer diameter of the large end is larger than the inner diameter of the through hole 7, but smaller than the nut size of the bolt 6, and the upper and lower surfaces of the outer diameter of the large end are in contact with the lower surface of the nut of the bolt 6 and the upper surface of the control board 4 respectively, which can attenuate the vibration energy transmitted to the heat dissipation shell 1 through the entire vehicle and then transmitted to the control board 4 through the bolt 4.
[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
