Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to a cleaning device for a vehicle radiator grille. Background Art

[0002] The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system consists of three parts: the water inlet chamber, the water outlet chamber, the main plate and the radiator core. The radiator cools the coolant that has reached a high temperature. The coolant flows in the radiator core and the air passes outside the radiator. The hot coolant cools down due to the heat dissipation to the air, and the cold air heats up due to absorbing the heat dissipated by the coolant. When the radiator tubes and fins are exposed to the airflow generated by the cooling fan and the airflow generated by the vehicle movement, the coolant in the radiator cools down.

[0003] According to an automobile radiator grille with application number CN202322195183.4, the utility model includes a mounting frame and a plurality of grille bodies, a top box is placed on the upper surface of the mounting frame, an adjustment mechanism for controlling the opening and closing of the grille body is provided inside the top box, and two disassembly mechanisms for disassembling the top box are provided on the upper surface of the mounting frame. The automobile radiator grille is provided with an adjustment mechanism so that when the automobile passes through gravel or dusty road conditions, the grille body can be conveniently closed through the adjustment mechanism, thereby avoiding the problem of gravel and dust entering the interior of the automobile when the automobile passes through gravel or dusty road conditions, thereby causing dust to enter the automobile engine or gravel to cause engine failure; at the same time, by providing a disassembly mechanism, when a mechanical failure occurs in the adjustment mechanism, the top box can be conveniently disassembled, thereby repairing or replacing the parts inside the top box, thereby improving the efficiency of the staff in repairing the adjustment mechanism.

Example 1

[0018] like Figure 2 and Figure 3 As shown, this embodiment provides a cleaning device for a vehicle radiator grille, comprising a circular frame, a radiator grille plate 2, a lifting mechanism, and a cleaning mechanism.

[0019] The circular frame includes two vertically arranged upright boards 3 , a top board 1 fixed between the tops of the two upright boards 3 , and a bottom board 4 fixed between the bottoms of the two upright boards 3 .

[0020] The radiator grille plate 2 is installed in the circular frame and its upper and lower ends are fixedly connected to the top plate 1 and the bottom plate 4 respectively. Each radiator grille plate 2 can rotate around its rotation axis.

[0021] The lifting mechanism includes a screw 9, a ball nut 10 and a motor 8; the screw 9 is vertically arranged on the front side of the radiator grille plate 2 and its two ends are rotatably mounted on the top plate 1 and the bottom plate 4 respectively; the ball nut 10 is threadedly connected to the screw 9 to form a screw substructure; the motor 8 is fixed on the top plate 1 or the bottom plate 4 and the drive shaft of the motor 8 is coaxially connected to the screw 9 to drive the screw 9 to rotate.

[0022] The cleaning mechanism includes a cleaning plate 7 , a support rod 11 , a compression spring 13 and bristles 14 .

[0023] The cleaning plate 7 is horizontally arranged between the radiator grille plate 2 and the ball nut 10. Two horizontally arranged through holes are provided in the middle of the cleaning plate 7 facing the ball nut 10. Both ends of the cleaning plate 7 extend to the front of the two vertical plates 3 respectively.

[0024] There are two support rods 11 and they are movably sleeved in the through holes of the cleaning plate 7 in a one-to-one manner. One end (front end) of the support rod 11 is fixedly connected to the outer wall of the ball nut 10, and the other end (rear end) of the support rod 11 extends to the rear side of the cleaning plate 7 and is provided with a limit plate 12 with a diameter larger than the support rod 11. The limit plate 12 is hemispherical on the side facing the radiator grille plate 2, so that the radiator grille plate 2 can smoothly pass through the limit plate 12 when rotating.

[0025] The bristles 14 are mounted on the side of the cleaning plate 7 facing the radiator grille plate 2 , and the length of the bristles 14 is greater than the distance from the rear side of the cleaning plate 7 to the rotation axis of the radiator grille plate 2 .

[0026] The compression spring 13 is sleeved outside the support rod 11 and is located between the cleaning plate 7 and the ball nut 10. The two ends of the compression spring 13 respectively support the cleaning plate 7 and the ball nut 10, so that the bristles 14 are close to the radiator grille plate 2.

[0027] The distance from the rear side of the cleaning plate 7 to the rotation axis of the radiator grille plate 2 is two-thirds to four-fifths of the rotation radius of the radiator grille plate 2, the length of the cleaning plate 7 moving forward along the support rod (away from the radiator grille plate 2) is greater than one-fifth to one-third of the rotation radius of the radiator grille plate 2, and the length of the bristles 14 is greater than or equal to the rotation radius of the radiator grille plate 2.

[0028] The cleaning plate 7 can slide back and forth along the support rod 11, and at the same time, the support rod 11 can drive the cleaning plate 7 to move up and down under the drive of the ball nut 10; when the radiator grille plate 2 is closed, the cleaning plate 7 can move backward to make way for the radiator grille plate 2 to rotate and close, and at the same time, the compression spring 13 is compressed by the cleaning plate 7 to store energy. After the radiator grille plate 2 is closed, the cleaning plate 7 is reset under the drive of the compression spring 13, so that the bristles 14 contact the closed radiator grille plate 2.

[0029] Here's how it works:

[0030] After the car stops, the radiator grille plate 2 will automatically close. During the closing process of the radiator grille plate 2, its outer edge contacts the limit plate 12 and the brush 14, pushing the limit plate 12 and the brush 14 forward, causing the cleaning plate 7 to move forward and make way. The closing action is completed after the radiator grille plate 0 passes the limit plate 12. Afterwards, the cleaning plate 7 is reset under the push of the compression spring 13, causing the brush 14 to contact the closed radiator grille plate 2.

[0031] After parking for a long time, dust will accumulate on the radiator grille plate 2. When the car is started again, the cleaning mechanism runs synchronously, the motor starts 8, the motor 8 drives the screw 9 to rotate, and the screw 9 drives the ball nut 10 to move up and down along the screw 9. The ball nut 10 then drives the cleaning plate 7 and the bristles 14 to move up and down several times through the support rod 11 to brush off the dust on the radiator grille plate 2. After that, the motor 8 drives the cleaning plate 7 and the bristles 14 to move to the top end through the screw 9 and the ball nut 10, and the radiator grille plate 2 is reopened to complete the cleaning of the dust. Example 2

[0032] In order to ensure that the bristles 14 maintain reliable contact with the radiator grille plate 2 after the radiator grille plate 2 is closed, thereby improving the cleaning efficiency, this embodiment adds the following structure on the basis of embodiment 1.

[0033] The cleaning device for the vehicle radiator grille also includes a tensioning mechanism, which includes a slide 5, a slider 6 and an automatic push rod 16; the slide 5 is two and is vertically arranged on the front side of the two vertical plates 3; the slider 6 is two and is slidably installed in the two slides 5 one by one, and a mounting hole is provided on the side of the slider 6 facing the cleaning plate 7; the automatic push rod 16 is two and is fixed one by one in the mounting holes of the two sliders 6, and the telescopic end of the automatic push rod 16 is fixedly connected to the cleaning plate 7. The automatic push rod 16 is any one or two of a small hydraulic rod, an electric push rod and a pneumatic push rod.

[0034] When the radiator grille 2 is closed or opened, the telescopic end of the automatic push rod 16 extends, moving the cleaning plate 7 and the bristles 14 away from the radiator grille 2, ensuring smooth closing or opening of the radiator grille 2. When closing is complete or before cleaning dust in the closed state, the telescopic end of the automatic push rod 16 shortens, moving the cleaning plate 7 closer to the radiator grille 2 and the bristles 14 in contact with the radiator grille 2.

[0035] The steps to clean up the dust are:

[0036] The telescopic end of the automatic push rod 16 is extended to move the cleaning plate 7 and the bristles 14 away from the radiator grille plate 2, thereby ensuring that the radiator grille plate 2 is closed smoothly.

[0037] After the radiator grille plate 2 is closed, the telescopic end of the automatic push rod 16 is shortened, so that the cleaning plate 7 and the bristles 14 are close to the radiator grille plate 2, and then the motor 8 is started, and the motor 8 drives the cleaning plate 7 and the bristles 14 to move up and down multiple times to brush off the accumulated dust on the radiator grille plate 2. After that, the motor 8 drives the cleaning plate 7 and the bristles 14 to move to the uppermost end, and the telescopic end of the automatic push rod 16 is extended, so that the cleaning plate 7 and the bristles 14 are away from the radiator grille plate 2, and the radiator grille plate 2 is reopened to complete the cleaning of the accumulated dust. Example 3

[0038] In order to improve cleaning efficiency and cleanliness, this embodiment adds the following structure on the basis of embodiment 1 or 2.

[0039] A plurality of atomizing nozzles 15 are evenly arranged on the side of the cleaning plate 7 facing the radiator grille plate 2. The atomizing nozzles 15 are connected to a water pump through a conduit. The water pump atomizes the water in the car water tank and sprays it onto the closed radiator grille plate 2 to lubricate the dust or lumps formed by the dust accumulation, making it easier to clean.

[0040] Other aspects of the present invention that are not described in detail are all conventional technologies known to those skilled in the art.

[0041] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements that are inherent to such process, method, article, or apparatus.

[0042] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
