Description

Technical Field

[0001] This invention relates to the field of automotive radiator under-protection technology, and in particular to a retractable automotive radiator under-protection assembly. Background Technology

[0002] Commercial vehicles often travel in complex road conditions. To effectively protect the radiator from damage by stones in front or below, car manufacturers usually install under-protection devices under the radiator. Since the engine is usually not horizontally mounted, the fan air blows onto the ground. When the vehicle is driving on dusty roads, it blows up dust, causing dust pollution. In this case, some vehicles currently have a wind deflector installed under the fan to suppress this phenomenon. However, the wind deflector changes the airflow behind the fan, and in some cases, the airflow may even flow back to the front of the radiator, reducing the radiator's heat dissipation capacity and causing the engine to malfunction due to overheating. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that the dustproof capability of the under-protection of automobile radiators is insufficient, which leads to a decrease in the heat dissipation capacity of the radiator and ultimately causes the engine to malfunction. The invention provides a retractable under-protection assembly for automobile radiators.

[0004] To achieve the objective, the technical solution of the present invention is: a retractable automotive radiator underbody protection assembly, comprising a radiator protective mesh body and a wind shield; the radiator protective mesh body is located in front of the radiator, and the wind shield is located between the radiator and the engine; characterized in that: it includes a drive motor, a telescopic baffle, a dust concentration sensor, a drive motor controller, and a buzzer; the drive motor has two components, each consisting of a motor and a drive gear, and is respectively located on the left and right sides below the radiator protective mesh body, and is respectively connected to the radiator protective mesh body through motor brackets; the left and right sides below the radiator protective mesh body are respectively provided with sliding grooves, the telescopic baffle consists of a baffle and a rack, the baffle is located in the sliding groove, the rack is located on both sides of the baffle, and the rack meshes with the drive gear of the drive motor.

[0005] The above technical solution is further defined as follows: the main body of the radiator protective net is connected to the sliding grooves and motor brackets on its lower left and right sides by welding, and the baffle is connected to the racks on its left and right sides by welding.

[0006] The above technical solution is further defined as follows: the vehicle engine ECU and the dust concentration sensor are respectively connected to the motor controller; the vehicle engine ECU transmits the water temperature signal to the motor controller; the signal from the dust concentration sensor is transmitted to the motor controller; the buzzer and the drive motor are respectively connected to the motor controller; the motor controller controls the working state of the buzzer and the drive motor; the power supply for the dust concentration sensor, the motor controller, the buzzer, and the drive motor is the vehicle power supply.

[0007] The above technical solution is further defined as follows: the dust concentration sensor, the drive motor controller, and the buzzer are all mounted on the vehicle frame.

[0008] The beneficial effects of this invention are: by integrating the radiator underguard and the wind deflector, a retractable radiator underguard assembly is provided.

Detailed Implementation

[0017] The present invention will now be described with reference to the accompanying drawings.

[0018] like Figures 1-5 As shown, a retractable automotive radiator underbody protection assembly includes a radiator protective mesh body 10, a wind shield 8, a drive motor 9, a telescopic baffle 7, a dust concentration sensor 6, a drive motor controller 5, and a buzzer 4. The radiator protective mesh body 10 is located in front of the radiator 1. The wind shield 8 is located between the radiator 1 and the engine 2. There are two drive motors 9, each consisting of a motor 16 and a drive gear 12, and they are respectively located on the left and right sides below the radiator protective mesh body 10, and are respectively connected to the radiator protective mesh body 10 through motor brackets 15. Each component is provided with a sliding groove 13; the telescopic baffle 7 is composed of a baffle 14 and a rack 11, with the baffle 14 located in the sliding groove 13 and the rack 11 located on both sides of the baffle 14, and the rack 11 meshing with the drive gear 12 of the drive motor 9; the radiator protective net body 10 is connected to the sliding groove 13 and the motor bracket 15 on its lower left and right sides by welding, and the baffle 14 is connected to the rack 11 on its left and right sides by welding, the welding process is simple and strong; the dust concentration sensor 6, the drive motor controller 5, and the buzzer 4 are all set on the frame 3 for convenient layout and aesthetic harmony.

[0019] The electrical control connection principle of this invention is as follows: Figure 6 As shown, the car engine ECU and dust concentration sensor are connected to the motor controller. The car engine ECU transmits the water temperature signal to the motor controller, and the dust concentration sensor transmits the signal to the motor controller. The buzzer and drive motor are connected to the motor controller, and the motor controller controls the working status of the buzzer and drive motor. The power supply for the dust concentration sensor, motor controller, buzzer and drive motor is the vehicle power supply.

[0020] The working principle of this invention is as follows: Figure 7 and combined Figures 1-5As shown, the motor controller 5 receives real-time water temperature signals from the engine 2 and dust concentration signals from the dust concentration sensor 6; the state of the telescopic baffle 7 can be determined by the rotation angle of the drive motor 9, and the initial state of the telescopic baffle 7 is the retracted state; when the engine 2 water temperature is below the limit and the dust concentration is above the limit, the drive motor controller 5 sends a command to the drive motor 9, which drives the drive gear 12 to rotate a certain angle via the motor 16, causing the rack 11 to drive the baffle 14 to slide backward a certain distance in the slide groove 13, thereby extending the telescopic baffle 7, changing the flow field, and suppressing dust. When both the dust concentration is below the limit and the engine 2 water temperature is above the limit, the telescopic baffle 7 can be extended to change the flow field and suppress dust. If any one or both of these situations occur simultaneously, and if the telescopic baffle 7 was in the retracted state at the previous moment, it will remain in the retracted state; if the telescopic baffle 7 was in the extended state at the previous moment, the drive motor controller 5 will send a command to the drive motor 9, which will drive the drive gear 12 to rotate by a certain angle via the motor 16, causing the rack 11 to drive the baffle 14 to slide forward a certain distance in the slide groove 13, thereby retracting the telescopic baffle 7; when the engine water temperature of 2 is higher than the limit and the dust concentration is also higher than the limit, in order to ensure the normal operation of the vehicle, the telescopic baffle 7 should be in the retracted state, and the buzzer 4 will sound a buzzing sound to indicate to people around the road to pay attention and avoid being adversely affected by the dust.

[0021] In summary, this invention provides a retractable radiator lower protection assembly by integrating a radiator lower protection and a wind deflector. This protection assembly can be extended by the drive motor controller according to the engine status and specific road conditions to suppress dust and ensure normal engine operation.

[0022] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations or substitutions made based on the description and drawings of the present invention should be included within the patent protection scope of the present invention.
