Description

Technical Field

[0001] The invention relates to the technical field of vehicle heat dissipation equipment, in particular to a louver structure of a front windshield radiator of an automobile. Background Art

[0002] The car shutter is a device of the car cooling system. It is generally installed between the car radiator and the air intake grille. It is composed of shutter blades, DC motors, transmission mechanisms, etc. The blades are controlled to rotate and open and close according to the engine radiator coolant temperature. The temperature in the car engine compartment is low (especially in the north and cold winter), and the engine has just started and the warm-up stage has not yet reached the optimal operating temperature. At this time, the shutters should be fully closed to reduce the air intake in the engine compartment and keep the engine compartment warm. When the radiator outlet temperature sensor detects that the temperature reaches 85 degrees, the fan in the engine compartment starts to operate, sucking the cold air outside the car into the engine compartment and blowing it onto the radiator. In order for the radiator to achieve the best heat dissipation effect, when the fan is turned on, the shutters must be fully opened so that the air intake in the engine compartment is sufficient.

[0003] In the prior art, in order to reduce the wind resistance of the shutters, the shutter blades are designed to be more in line with the principles of fluid mechanics. However, on the vehicle, the rear side of the shutters is installed with a radiator device with a more complex shape, and the gaps between the radiator devices are irregular, so the airflow is not smooth and the flow resistance is large. Therefore, when the vehicle is running at high speed, if the shutter opening is large, a large amount of airflow enters the vehicle body and collides with the surface of the radiator device. Although the cooling effect is good, it also greatly increases the resistance of the vehicle's driving, resulting in increased fuel consumption. Therefore, most vehicles tend to completely close the shutters when driving at high speeds, but at the same time, it also reduces the heat dissipation effect of the vehicle engine. Long-term high-speed driving will cause damage to the engine. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 A car windshield radiator shutter structure includes a window frame 1 and a blade 2, both ends of the blade 2 are connected to a rotating shaft 3, the middle of the window frame 1 is provided with an inner box, the rotating shafts 3 at both ends of the blade 2 are rotatably connected to the window frame 1 and the middle of the inner box, and an angle adjustment device 4 is provided in the inner box. Figure 1 The angle adjustment device 4 includes a main bracket 401, which is arranged in the middle of the inner box. One end of the rotating shaft 3 located in the inner box is fixedly sleeved with a rotating rod 402. The other end of the rotating rod 402 extends to the middle of the main bracket 401, and the rotating rod 402 is rotatably connected to the main bracket 401 through a pin rod 403. A driving end of a telescopic rod 404 is connected to one end of the main bracket 401, and the fixed end of the telescopic rod 404 is installed on the window frame 1. When the telescopic rod 404 is extended, it pushes the main bracket 401 to move upward, driving the rotating rod 402 to rotate along the central axis of the rotating shaft 3. Since the rotating rod 402 is fixedly connected to the rotating shaft 3, the rotating shaft 3 also rotates, thereby realizing the adjustment of the opening and closing angle of the blade 2.

[0024] See attached Figure 1 The blade 2 includes a main blade 201 and an auxiliary blade 202. The connecting ends of the main blade 201 and the auxiliary blade 202 are inclined, and the connecting end of the main blade 201 is located at the rear side of the connecting end of the auxiliary blade 202. Therefore, when the wind blows toward the blade 2 from the outside, the main blade 201 can provide support for the auxiliary blade 202. Figure 4The connecting end of the main leaf 201 is provided with a magnet 204, and the connecting end of the auxiliary leaf 202 is provided with a magnetic plate 203. Therefore, under normal conditions, the main leaf 201 and the auxiliary leaf 202 are combined into one by the attraction of the magnet 204 and the magnetic plate 203 to realize the opening and closing of the entire blade 2.

[0025] See attached Figure 1 An opening and closing driving device 5 is installed in the window frame 1, and an auxiliary driving component 6 is connected to the driving end of the opening and closing driving device 5. An auxiliary driving component 6 is provided at one end of the rotating shaft 3 connected to each auxiliary leaf 202. Figure 2 and attached Figure 3 The opening and closing driving device 5 includes a wind plate 7, a guide plate 8 and a linkage assembly 9. The end of the wind plate 7 close to the window frame 1 is connected to a guide rod 701. The guide plate 8 is provided with a guide groove 804. The linkage assembly 9 includes a transmission plate 901, a horizontal support seat 902, a fan tooth plate 903 and a gear rod 904. The bottom end of the transmission plate 901 is slidably connected to the horizontal support seat 902. The fan tooth plate 903 is fixedly connected to the bottom end of the horizontal support seat 902. The edges of the fan tooth plate 903 and the gear rod 904 are both provided with transmission teeth and the transmission teeth of the two are meshed. A through groove is provided on the transmission plate 901. The guide rod 701 passes through the guide groove 804 and the through groove. The guide rod 701 is provided with a limit plate located on the front and rear sides of the guide groove 804; the guide plate 8 includes an inner plate section 801, a transition section 802 and an outer plate section 803, the transition section 802 is connected between the inner plate section 801 and the outer plate section 803, and the lateral distance value between the inner plate section 801 and the outer plate section 803 is the lateral width value of the wind plate 7. When the wind plate 7 and the guide rod 701 move to the inner plate section 801, the wind plate 7 enters the middle part of the window frame 1, so that the airflow cannot blow on the wind plate 7, and when the wind plate 7 and the guide rod 701 move to the outer plate section 803, the wind plate 7 is completely exposed on the outside of the window frame 1, so that the airflow can blow on the wind plate 7.

[0026] See attached Figure 2 The auxiliary drive assembly 6 includes a vertical transmission rod 601, a push rod 602 and a return spring 603. The vertical transmission rod 601 is vertically arranged on the side of the window frame 1, and the vertical transmission rod 601 is connected to the gear rod 904. The push rod 602 is connected to the vertical transmission rod 601. The end of the push rod 602 away from the vertical transmission rod 601 is located on one side of the rotating shaft 3 and close to the rotating shaft 3. The return spring 603 is arranged on one side of the rotating shaft 3 and is symmetrical to the vertical transmission rod 601. The return spring 603 is not connected to the rotating shaft 3. One end of the return spring 603 is fixedly connected to the inner wall of the window frame 1. A positioner is arranged inside the window frame 1. The positioner is used to fix the wind plate 7. See the attached Figure 6Under normal circumstances, the positioner fixes the wind plate 7 inside the window frame 1, so that the wind plate 7 does not extend out of the side of the window frame 1 and cannot come into contact with the airflow. When the wind plate 7 needs to be used, the wind plate 7 is pushed out of the window frame 1, and the position of the wind plate 7 can be controlled by electromagnet adsorption and other technologies.

[0027] See attached Figure 5 , the window frame 1 is installed at the front end of the vehicle body 10, a radiator device 11 is arranged inside the vehicle body 10, side air ducts 1001 are opened at both ends of the vehicle body 10, and valves 1002 are arranged on the side air ducts 1001. The valves 1002 on the side air ducts 1001 on both sides are opened alternately, and if the left main leaf 201 and the auxiliary leaf 202 are misaligned, the right valve 1002 is opened, and if the right main leaf 201 and the auxiliary leaf 202 are misaligned, the left valve 1002 is opened, extending the air flow path, so that the air can completely absorb the heat and take the heat out of the vehicle body 10. The position of the auxiliary leaf 202 can be measured by arranging a position sensor on the auxiliary leaf 202, so that the position of the auxiliary leaf 202 can be known according to the value of the position sensor, and then the opening and closing of the valve 1002 can be controlled.

[0028] Due to the intermittent misalignment of the main blades 201 and the auxiliary blades 202, the airflow can intermittently enter the vehicle body 10. After the air enters the vehicle body 10, the main blades 201 and the auxiliary blades 202 close quickly, and the air entering the vehicle body 10 is not pushed by continuous airflow. Moreover, since the space in the vehicle body 10 increases rapidly compared to the openings of the main blades 201 and the auxiliary blades 202, its impact force is greatly reduced, and its flow rate gradually becomes consistent with the speed of the vehicle. The airflow rate at the air duct 1001 outside the vehicle is large and the air pressure is small. Therefore, the air in the vehicle body 10 flows out from the side air duct 1001 and simultaneously takes out the heat from the radiator device 11, thereby realizing the function of intermittent cooling under high-speed driving.

[0029] The method of use of the present invention is as follows:

[0030] When the blades 2 are in normal use, the blades 2 are rotated by controlling the extension and retraction of the telescopic rod 404, thereby realizing the size function of the opening and closing of the blades 2;

[0031] When the vehicle is running at high speed and the blade 2 is closed, the control positioner pushes the wind plate 7 out of the middle of the window frame 1, so that the airflow blows on the wind plate 7. The impact of the airflow causes the guide rod 701 to drive the wind plate 7 to move along the guide groove 804. Figure 3As shown, when the guide rod 701 moves to the right half of the guide plate 8, it gradually extends out of the outside of the window frame 1, and the airflow blows the wind plate 7 to rotate clockwise along the guide groove 804. At this time, the transmission plate 901 is tilted to the right with one end close to the horizontal support seat 902 as the center. Due to the meshing of the fan tooth plate 903 and the transmission teeth on the toothed rod 904, the toothed rod 904 moves to the left, thereby driving the push rod 602 to the left, and the push rod 602 does not contact the rotating shaft 3. The rotating shaft 3 is reset to the state where the auxiliary leaf 202 is connected to the main leaf 201 under the action of the reset spring 603; when the guide rod 701 rotates to the left half of the guide plate 8, it drives the toothed rod 904 to move to the right, thereby causing the push rod 602 to move to the right and push the rotating shaft 3 to rotate about the connection point between the rotating shaft 3 and the window frame 1, so that the main leaf 201 and the auxiliary leaf 202 are staggered, see the attached Figure 6 , the airflow enters the interior of the vehicle body 10 from the openings of the left main blade 201 and the auxiliary blade 202, and after contacting the radiator device 11, it flows out from the right valve 1002, thereby dissipating the heat to the outside of the vehicle body 10. When the guide rod 701 moves to the left half of the guide plate 8 and is located on the inner plate section 801, since the airflow cannot impact the wind plate 7, the wind plate 7 at this time moves by inertia. In order to prevent the thrust generated by the inertial movement of the wind plate 7 from being unable to drive the push rod 602 to push the auxiliary blade 202 away, a steering device can be provided at the connection between the gear rod 904 and the vertical transmission rod 601. When the gear rod 904 moves to the left, the vertical transmission rod 601 and the push rod 602 move to the right.
