Technical Field

[0001] This utility model relates to the field of vehicle air conditioning technology, specifically to an electrical control box with vibration reduction and heat dissipation functions. Background Technology

[0002] Automotive air conditioning systems have multiple control modules, such as compressor drive units, fan drive units, and an overall control module. Bus air conditioning systems use individual, independent drive and control modules; for example, the compressor drive unit, fan drive module, and control unit are all independently packaged. These are installed separately and connected by wiring harnesses, resulting in a large footprint, numerous wiring interfaces, complex layout, and difficulties in troubleshooting. Furthermore, to ensure the normal operation of multiple drive and control modules during vehicle operation, vibration damping mechanisms are required, further increasing installation complexity. Therefore, an integrated electrical control enclosure is needed that simultaneously ensures heat dissipation and vibration damping. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an electrical control box with vibration reduction and heat dissipation functions, which integrates the drive module and the control module into one unit, uses an overall heat dissipation base plate to improve heat dissipation capacity, and uses CAN communication to connect the modules inside the electrical control box, reducing wiring harness interfaces.

The vibration damping spring is sleeved on the support rod, and a baffle is provided on the upper side of the vibration damping spring. The electrical control box is provided with a mounting plate, and the support rod passes through the mounting plate.

[0010] The advantage of adopting the above technical solution is that the support rod plays a limiting role. Compared with the direct installation method in the existing technology, the vibration damping spring can provide support for the electrical control box and play a role in vibration reduction.

[0011] Furthermore, a fixing plate is connected to the bottom of the support rod. The fixing plate is rotatable and has a strip-shaped hole.

[0012] The advantages of adopting the above technical solution are that the fixing plate serves as a connector, and the rotatable fixing plate is suitable for various installation situations. It can avoid other components by rotating, and the strip hole design facilitates installation without the need for fine adjustment.

[0013] Furthermore, an air inlet is provided on the side of the electrical control box, and an air outlet is provided on the opposite side of the electrical control box. The cooling fan is installed outside the air outlet and blows air towards the outside of the electrical control box.

[0014] The advantage of adopting the above technical solution is that the cooling fan is used for heat dissipation, exhausting the hot air inside the electrical control box and enhancing the heat dissipation function of the entire heat dissipation box.

[0015] Furthermore, a receiving base plate is provided at the bottom of the fixing plate, a receiving groove is provided in the receiving base plate, a connecting plate is provided in the receiving groove, springs are provided on both sides of the connecting plate to connect with the inner wall of the receiving groove, and the connecting plate and the fixing plate can be detachably connected.

At the same time, the base plate and connecting plate can be selected according to the usage environment. They can be omitted in the case of low vibration intensity and installed in the case of high vibration intensity.

[0017] Furthermore, the connecting plate is provided with multiple placement slots, and ball bearings are provided in the placement slots. The ball bearings (63) roll in the receiving slots (61).

[0018] The advantage of adopting the above technical solution is that the ball connection allows the connecting plate to have multiple degrees of freedom in multiple directions, while the spring is set for limiting and damping, so that the electrical control box has a vibration damping function in the horizontal direction.

[0019] Furthermore, a base plate is provided inside the receiving cavity, and the base plate is provided with multiple sliding grooves. Multiple nuts are provided in the sliding grooves, and the nuts are slidably disposed in the sliding grooves.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] like Figure 1-2 As shown, this utility model discloses an electrical control box with vibration reduction and heat dissipation functions, comprising:

[0035] The electrical control box 1 has an internal cavity and a removable top cover 2;

[0036] Vibration damping component 3 is connected to the electrical control box 1 and is used to reduce the vibration experienced by the electrical control box 1 during vehicle operation;

[0039] Furthermore, the vibration damping component 3 includes a support rod 31 and a vibration damping spring 35. The vibration damping spring 35 is sleeved on the support rod 31. A baffle 32 is provided on the upper side of the vibration damping spring 35. The baffle 32 has a through hole and slides up and down along the support rod 31. The bottom of the baffle 32 is supported by the vibration damping spring 35 and plays a vibration damping function. The electrical control box 1 is provided with a mounting plate 33. The support rod 31 passes through the mounting plate 33. The mounting plate 33 is fixedly connected to the baffle 32. There are 4 vibration damping components 3, which are installed at the four corners of the electrical control box 1.

[0040] The advantage of adopting the above technical solution is that the support rod 31 serves as a limit, and compared with the direct installation method in the prior art, the vibration damping spring 35 can provide support for the electrical control box 1 and play a role in vibration damping.

[0041] Furthermore, a fixing plate 34 is connected to the bottom of the support rod 31. The fixing plate 34 is rotatable and has a slotted hole. The fixing plate 34 is fixedly connected to the support rod 31. The support rod 31 is rotatable, allowing the fixing plate 34 to rotate. External threads can be provided at the bottom of the support rod, and the fixing plate has a threaded hole to achieve a threaded connection.

[0043] Furthermore, an air inlet 11 is provided on the side of the electrical control box 1, and an air outlet is provided on the opposite side of the electrical control box 1. A cooling fan 5 is installed outside the air outlet and blows air towards the outside of the electrical control box 1. The cooling fan 5 is fixedly installed. When blowing air, it drives the air inside the electrical control box 1, increases the internal air flow, and improves the heat dissipation function of the entire electrical control box. A filter screen 14 is provided at the air inlet 11. The filter screen 14 is fixedly installed outside the air inlet 11. The filter screen 14 can effectively prevent impurities from entering the electrical control box 1 and effectively reduce the dust inside the electrical control box 1.

A connecting plate 62 is provided inside the receiving groove 61. Springs 64 are provided on both sides of the connecting plate 62 and connected to the inner wall of the receiving groove 61. The number of springs 64 can be 4-8, distributed around the connecting plate 62, so that the connecting plate 62 can move in multiple directions. One end of the spring 64 is fixedly installed to the side wall of the receiving groove 61, and the other end is fixedly installed to the side of the connecting plate 62. A buffer block made of rubber is also installed inside the spring and fixedly connected to the connecting plate to play a buffering role.
