Description

Technical Field

[0001] The invention relates to the field of automobile accessories, and in particular to an automobile front windshield shielding plate with variable width. Background Art

[0002] With the rapid development of modern society, cars have entered thousands of households. When people are driving, the sun shines through the front windshield and shines into their eyes, which makes them unable to open their eyes and very uncomfortable. They can only drive reluctantly, which not only affects driving safety, but also hurts their eyes and skin. In summer, when the car is driving or parked outdoors, the sun shines through the front windshield, causing the temperature inside the car to rise significantly, increasing the energy consumption of air conditioning. When driving in heavy rain and snow, the wipers must be adjusted to the fast gear. At this time, the rain and snow affect the vision, and the wipers swing left and right quickly, causing the driver to feel dizzy and affecting driving safety. In the cold winter in the north, when the car is parked outdoors in rainy and snowy weather, the front windshield and wipers will be frozen by the rain and snow, delaying the use of the car. Since the front windshield of the car is small on the top and large on the bottom, in order to make the width of the storage box not exceed the width of the roof, which affects the appearance, it is best to allow the shielding plate to become wider after being extended and narrower before being retracted into the storage box. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a variable-width automobile front windshield shield that is simple in structure, easy to use, and can increase the comfort of drivers and passengers and the convenience of using the vehicle.

[0004] To achieve the above objectives, the technical solution of the present invention is: a car front windshield shield with variable width, characterized in that it includes a main shield, an auxiliary shield and a main shield transmission mechanism, the auxiliary shield is slidably connected to the main shield or the auxiliary shield can be flipped and connected to both sides of the main shield.

[0005] The main shielding plate is provided with a slot hole penetrating through both sides of the main shielding plate, and auxiliary shielding plates are respectively provided on both sides of the slot hole. The auxiliary shielding plates slide in and out of the slot hole through sliding rails, and the main shielding plate is provided with a limiting device for controlling the sliding distance of the auxiliary shielding plate.

[0006] The limiting device is an electric push rod, one end of which is connected to the auxiliary shielding plate, and the other end of which is connected to the bottom wall of the slot hole.

[0007] The limiting device is a positioning screw 1, and screw holes are arranged on the end of the main shielding plate and the side wall of the auxiliary shielding plate.

[0008] Auxiliary shielding plates are respectively arranged on both sides of the main shielding plate, and the auxiliary shielding plates and the main shielding plates are connected together through hinges.

[0009] The main baffle transmission mechanism includes a motor and a transmission lead screw. The main baffle is connected to the transmission lead screw through a transmission nut, and the transmission lead screw is in transmission connection with the motor.

[0010] A guide sleeve is installed below the main baffle. There is a guide rail inside the guide sleeve, and the guide rail is installed on the cross bar through a guide rail bracket. There is a cross bar bracket below the cross bar.

[0011] There is a positioning screw two below the guide sleeve.

[0012] A storage box is installed outside the main baffle.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention adopts the cooperation structure of the main and auxiliary baffles to achieve the purpose of variable width of the baffle. The baffle set in this way can not only make the width of the storage box not exceed the width of the car roof, blend in with the car roof, be small and beautiful, but also make the baffle completely block the front windshield of the car after being opened, and can effectively block sunlight, rain, snow and hail.

[0014] 2. The present invention drives the telescopic movement of the main baffle through a motor + transmission lead screw. The transmission structure is simpler. Compared with the traditional push rod transmission, the cost is lower, the failure rate is less, and the installation and maintenance are very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
