Description

Technical Field

[0001] This utility model relates to the technical field of dual-blowing mode automotive radiator fan assembly, specifically a dual-blowing mode automotive radiator fan assembly. Background Technology

[0002] The main function of a dual-blowing mode automotive radiator fan assembly is to ensure that the vehicle maintains an appropriate temperature range under various operating conditions, and this is achieved through the coordinated operation of two fans.

[0003] For example, in a dual-blowing mode radiator fan assembly with authorization announcement number "CN218151140U", the motors on the intake fan and the blower fan are in the same vertical section. The intake and blower fans are independently controlled by the vehicle's ECU (Electronic Control Unit). The impeller of the blower fan is larger than that of the intake fan. A counterweight and an openable ventilation door are arranged below the intake fan. This achieves the technical goal of good gravity balance, thereby improving the vibration and reducing noise during fan operation. However, in the use of the dual-blowing mode automotive radiator fan assembly, the rotation of the fan will generate vibration. This vibration will cause wear and vibration at the connection between the dual-blowing mode automotive radiator fan assembly and the vehicle body, increasing the noise during the use of the dual-blowing mode automotive radiator fan assembly. Utility Model Content

A vertical plate is fixedly connected to the top of the inner wall of the bracket. A protective structure is connected to the outer wall of the bracket. A control structure is connected to the bottom of the bracket. The top of the control structure is connected to the bottom of the vertical plate.

[0007] Preferably, the protective structure includes curved plates and pads, the inner sides of the multiple curved plates are respectively fixed to the left and right sides of the outer wall of the bracket, the grooves of the outer wall of the curved plates are inserted into the outer wall of the pads, and the outer wall of the curved plates is threaded with a first bolt.

[0008] Preferably, the inner wall of the pad is inserted into the outer wall of the bracket.

[0009] Preferably, the control structure includes a horizontal plate and a vertical plate. The top of the horizontal plate fits into the bottom of the bracket, the front groove of the horizontal plate is inserted into the outer wall of the vertical plate, and the left and right sides of the front of the vertical plate are respectively threaded with second bolts.

[0010] Preferably, the top of the horizontal plate is fixedly connected to the bottom of the vertical plate.

[0011] Preferably, the rear of the outer wall of the second bolt is threaded to the front circular opening of the cross plate.

[0012] The present invention proposes a dual-blowing mode automotive radiator fan assembly, which has the following advantages: The inner wall of the protective pad is inserted into the outer wall of the bracket through the protective structure. At this time, the outer wall of the protective pad is inserted into the groove of the outer wall of the curved plate. Then, the protective pad is fitted to the connection point with the vehicle body, and the front of the curved plate is also fitted to the vehicle body.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Please see Figure 1-5In this embodiment, a dual-blowing mode automotive radiator fan assembly includes a bracket 1 and a fan 4. The fan 4 is model pro-dm. The outer wall of the bracket 1 is fixedly connected to the outer wall of the fan 4. A vertical plate 5 is fixedly connected to the top of the inner wall of the bracket 1. A protective structure 2 is connected to the outer wall of the bracket 1. A control structure 3 is connected to the bottom of the bracket 1. The top of the control structure 3 is connected to the bottom of the vertical plate 5.

[0021] The protective structure 2 includes curved plates 201 and pads 202. The inner sides of multiple curved plates 201 are fixed to the left and right sides of the outer wall of the bracket 1, respectively. The grooves on the outer wall of the curved plates 201 are inserted into the outer wall of the pads 202. The pads 202 are made of rubber and can prevent hard collisions between the bracket 1 and the vehicle body. The outer wall of the curved plates 201 is threaded with a first bolt 203. The inner wall of the pads 202 is inserted into the outer wall of the bracket 1.

[0022] The inner wall of the protective pad 202 is inserted into the outer wall of the bracket 1 through the protective structure 2. At this time, the outer wall of the protective pad 202 is inserted into the groove of the outer wall of the curved plate 201. Then, the protective pad 202 is attached to the connection with the vehicle body. At this time, the front of the curved plate 201 is also attached to the vehicle body. Then, the first bolt 203 passes through the curved plate 201 from back to front and is threaded to the vehicle body. At this time, the bracket 1 will press the protective pad 202 tightly onto the vehicle body. Then, the connector at the other end of the wire is inserted into the interface of the vehicle body. When the vehicle body provides power to make the fan 4 work, the problem of wear and vibration at the connection between the dual-blowing mode car radiator fan assembly and the vehicle body is eliminated, and the noise of the dual-blowing mode car radiator fan assembly during use is reduced.

[0023] The control structure 3 includes a horizontal plate 301 and a vertical plate 302. The top of the horizontal plate 301 is attached to the bottom of the bracket 1. The slot on the front of the horizontal plate 301 can lead to the wire. The slot on the front of the horizontal plate 301 is inserted into the outer wall of the vertical plate 302. The left and right sides of the front of the vertical plate 302 are respectively threaded with second bolts 303. The top of the horizontal plate 301 is fixed to the bottom of the vertical plate 5. The second bolts 303 play a fixing role for the vertical plate 302 and the horizontal plate 301. The rear of the outer wall of the second bolt 303 is threaded to the round opening on the front of the horizontal plate 301.

[0024] Working principle:

[0025] Dual-blowing mode car radiator fan assembly wiring connections:

[0026] The second bolt 303 is rotated forward through the straight plate 302, causing the rear of the outer wall of the second bolt 303 to disengage from the round opening on the outer wall of the horizontal plate 301. Then, the straight plate 302 is pulled forward to disengage from the horizontal plate 301. Next, the wire connector is inserted into the interface on the front of the fan 4. Then, the outer wall of the wire is inserted into the groove on the outer wall of the horizontal plate 301. Then, the straight plate 302 is inserted back into the original position of the horizontal plate 301. The thread of the second bolt 303 passes through the straight plate 302 and is threadedly connected to the round opening on the outer wall of the horizontal plate 301, thus completing the wire fixing. The dual fans 4 on the inner wall of the bracket 1 form a dual-blowing mode car radiator.

[0027] Dual-blowing mode car radiator fan assembly installation:

[0028] The inner wall of the pad 202 is inserted into the outer wall of the bracket 1. At this time, the outer wall of the pad 202 is inserted into the groove of the outer wall of the curved plate 201. Then, the pad 202 is attached to the connection point of the vehicle body. At this time, the front of the curved plate 201 is also attached to the vehicle body. Then, the first bolt 203 passes through the curved plate 201 from back to front and is threaded to the vehicle body. At this time, the bracket 1 will press the pad 202 tightly onto the vehicle body. Then, the connector at the other end of the wire is inserted into the interface of the vehicle body. When the vehicle body provides power to make the fan 4 work, the pad 202 can prevent the bracket 1 from having a hard collision with the vehicle body through its own rubber material, thereby reducing the generation of noise.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
