Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, an automobile front protection lower guide plate with a backflow prevention function comprises a guide plate 1 with an L-shaped structure and a housing 2 arranged above the guide plate 1, a fixed plate 3 is arranged above one side of the housing 2 close to an opening of the guide plate 1, the guide plate 1 extends into the upper side of one side of the housing 2 and is rotatably connected with a swinging plate 4, a pull rod 5 is hinged at the middle position of one side of the swinging plate 4 far away from the guide plate 1, the other end of the pull rod 5 is hinged with a cover plate 6 in sliding connection with the side edge of the top of the guide plate 1, the cover plate 6 is movably sleeved with the housing 2, an exhaust hole 7 penetrating through the guide plate 1 is arranged below one end of the cover plate 6 extending out of the housing 2, a connecting rod 8 is fixedly connected with one side of one end of the swinging plate 4 far away from the guide plate 1, the other end of the connecting, the mounting groove 11 rather than coaxial arc structure is seted up to slide 10's top outer lane, and mounting groove 11 cup joints with conflict board 9 slides, the sensor of contradicting with conflict board 9 is installed to the inside wall in top of mounting groove 11, one side that fixed plate 3 was kept away from to housing 2 is installed and is bled housing 13, it has blast pipe 14 to bleed housing 13 fixed the cup joint, exhaust passage 15 that runs through housing 13 is installed to blast pipe 14's outer lane, exhaust passage 15 keeps away from one side of 2 one end openings of housing articulated and guard plate 16.

Furthermore, the protection plate 16 is hinged with the air exhaust cover shell 13 through a hinge, one side of one end of the hinge of the protection plate 16 is fixedly connected with a blocking rod with an arc-shaped structure, the blocking rod is movably sleeved with the air exhaust cover shell 13, one end of the blocking rod extending into the air exhaust cover shell 13 is fixedly connected with a baffle, and the blocking rod and a deflection shaft of the hinge are coaxially arranged.

In particular, a heat dissipation module 17 and an exhaust fan 18 are installed on the inner side wall of the top of the housing 2 along the direction from the fixing plate 3 to the air exhaust housing 13.

It is worth mentioning that the sensor is a proximity switch, and the distance between the sensor and the fixing plate 3 is smaller than the length of the touch plate 9.

Further, one end of the mounting groove 11 near the fixed plate 3 extends to the end of the fixed plate 3.

In addition, the distance between the end of the abutting plate 9 close to the fixed plate 3 is smaller than the distance between the top of the pull rod 5 and the fixed plate 3, and the sensor and the exhaust fan 18 are connected with the automobile internal controller.

The working principle is as follows: when the automobile is used, when the automobile is started and does not run, because the automobile does not run, less gas or no gas enters the housing 2, and no thrust for pushing the swinging plate 4 to move away from the fixed plate 3 is generated, at this time, the sealing cover plate 6 on the pull rod 5 on one side of the swinging plate 4 is positioned at the leftmost position, so that the exhaust hole 7 at the bottom of the guide plate 1 leaks out, and the gas in the engine compartment can be exhausted from the interior of the guide plate 1; meanwhile, the touch plate 9 always collides with the left sensor, the left sensor is triggered at this time, then a controller in the automobile controls the exhaust fan 18 to start, air draft operation is carried out on the engine compartment, the touch plate 9 moves towards the right sensor during the air draft operation until the touch plate 9 does not collide with the left sensor, the swinging plate 4 is ensured to be opened to a proper angle, external gas is conveyed into the housing 2 from between the guide plate 1 and the fixed plate 3, heat exchange is carried out through the heat dissipation module 17, and the heated gas enters the air exhaust housing 13;

when the automobile air conditioner needs to be heated, an exhaust fan positioned in the exhaust pipe 14 is started, hot air is pumped into an air inlet pipe of the automobile air conditioner along the exhaust pipe 14, and when the automobile air conditioner does not need to be heated, hot air enters an engine compartment along an exhaust passage 15, so that air in the engine compartment is exchanged;

when the air pressure in the engine compartment is too high, the protection plate 16 is pushed to flow towards the air extraction cover 13, so that the air in the engine compartment is prevented from entering the air extraction cover 13 and being conveyed to the interior of the automobile by the exhaust pipe 14;

when the automobile runs, a large amount of outside wind enters the housing 2, and continues to push the sensor on the right side of the swinging plate 4 to move in the direction, at this time, the abutting plate 9 is not in contact with the sensor on the left side, and meanwhile, when the abutting plate 9 deflects to the rightmost side, the swinging plate 4 is in an inclined state towards the direction of the fixed plate 3, so that the swinging plate 4 can be reset to an initial state under the action of gravity when the automobile stops, at this time, the controller controls the exhaust fan 18 to be closed, and when the exhaust fan 18 is closed, the sensor on the left side is not triggered, it is shown that the outside wind speed on the surface is enough to push the swinging plate 4 to; when exhaust fan 18 closed, when left sensor was triggered, it is not enough to promote swinging plate 4 and open suitable angle to show external wind speed, exhaust fan 18 needs to be opened and auxiliary convulsions are carried out, thereby it is stable to ensure the car air inlet, conveniently discharge the inside tail gas in automobile engine cabin, avoid engine cabin atmospheric pressure too big, the effectual heat balance that improves the engine cabin, make the air velocity that gets into the inside of car keep in certain within range, make the warm air inlet speed of car air conditioning balanced, improve the heating quality, avoid the inside tail gas in engine cabin to flow back to air conditioner inlet end.
