Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology and relates to a louver structure for vehicles. Background Technology

[0002] Vehicle louvers are installed in front of the radiator to control the airflow into the radiator, thereby achieving a cooling effect. They also prevent larger objects from entering the radiator and can reduce damage from external impacts to some extent. There are two types of louvers: fixed louvers and louvers with opening and closing functions. Both fixed and louvers achieve good heat dissipation. In cold weather, closing the louvers reduces heat loss; when driving on water or muddy roads, closing the louvers prevents water and dirt from entering the vehicle.

[0003] The louver with opening and closing function uses multiple blades. The opening and closing of the louver is achieved by controlling the angle of multiple blades. When closed, the sealing effect is poor, and the efficiency of reducing heat loss is low in cold weather. In particular, when the vehicle is traveling on water, a large amount of water may enter the vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a radiator louver with opening and closing function for vehicles. The louver has good sealing performance and can adjust the opening and closing state according to different operating conditions of the vehicle to prevent heat loss and prevent dirt or water from entering the vehicle.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A louver structure for a vehicle includes a cylinder 2, a fixed seat 1, a shift fork 3, a rotating arm 4, a movable louver 5, a fixed louver 6, and a frame assembly 7.

[0007] The frame assembly 7 has a square frame structure. The upper wall of the frame assembly 7 is provided with multiple evenly distributed through holes, and the lower wall is provided with multiple evenly distributed blind holes.

[0009] One end of cylinder 2 is connected to fixed seat 1 by a pin, fixed seat 1 is connected to vehicle body, and the other end of cylinder 2 is connected to shift fork 3 by a pin. The extension and retraction of cylinder 2 can push shift fork 3 to move.

[0010] The shift fork 3 is a long rod structure with multiple U-shaped holes spaced apart on its upper surface; one side of the L-shaped structure of the rotating arm 4 is fixed to the U-shaped hole of the shift fork 3 by a washer and a stop pin, and the other side of the rotating arm 4 passes through the through hole in the upper wall of the frame assembly 7 and is fixed to one end of a movable louver 5; the movable louver 5 is located inside the frame assembly 7, and its other end can rotate in a blind hole on the lower wall of the frame assembly 7; the multiple U-shaped holes of the shift fork 3 are slidably connected to the multiple movable louvers through the rotating arm, so that the movement of the shift fork can drive the multiple movable louvers to rotate;

[0011] A fixed louver 6 is arranged between two adjacent movable louvers 5; the two ends of the fixed louver 6 are fixed between the upper and lower walls of the frame assembly 7.

[0012] Furthermore, when cylinder 2 is in the retracted state, the louvers are in the open state, and there is a gap between the movable louver 5 and the fixed louver 6 to meet the heat dissipation requirements of the radiator.

[0013] Furthermore, when cylinder 2 is in the extended state, the louvers are in the closed state. The movable louver 5 rotates under the pushing action of the fork 3. After rotating, the movable louver 5 will overlap and contact the fixed louver 6 and be compacted, thereby achieving a sealing effect.

[0014] Furthermore, the edges of the movable louvers 5 are designed with stepped vulcanized rubber, which further enhances the sealing effect.

[0015] Furthermore, the fixed louvers 6 are fixed to the frame assembly 7 by welding.

[0029] Each movable louver 5 has two ends located in the through hole on the upper wall and the blind hole on the lower wall of the frame assembly 7, respectively; the movable louver 5 and the fixed louver 6 have a bending structure.

[0030] The shift fork 3 is a long rod structure with multiple U-shaped holes spaced apart on its upper surface; one side of the L-shaped structure of the rotating arm 4 is fixed to one of the U-shaped holes of the shift fork 3 by a washer and a stop pin; the other side of the rotating arm 4 passes through a through hole in the upper wall of the frame assembly 7 and is fixed to one end of a movable louver 5; the movable louver 5 is located inside the frame assembly 7, and its other end can rotate in a blind hole on the lower wall of the frame assembly 7; the multiple U-shaped holes of the shift fork 3 are slidably connected to the multiple movable louvers through the rotating arm, so that the movement of the shift fork can drive the multiple movable louvers to rotate.

[0034] When cylinder 2 is in the extended state, the louvers are in the closed state. The movable louver 5 rotates under the pushing action of the fork 3. After rotation, the movable louver 5 overlaps and contacts the fixed louver 6, and is pressed firmly, thus achieving the sealing effect of the louvers. The edges of the movable louver 5 are designed with stepped vulcanized rubber to further enhance the sealing effect. See [link / description]. Figure 3 As shown.
