[0005] According to the swing arm type windshield lifting mechanism, the output shaft of the motor gear box is connected to the front swing arm and the shaft pressing plate on both sides, and the bottom plate is a sheet metal part, which is stamped into a certain angle step on both sides of the middle position as a limiting surface when the shaft pressing plate rotates.

[0006] According to the swing arm type windshield lifting mechanism, the rear swing arm and the front swing arm are movably connected to the pin shaft near the top and the bottom, and a plurality of pin shafts are movably connected to the support and the glass mounting strip.

[0007] The above-mentioned scheme has at least one of the following beneficial effects: the swing arm type windshield lifting mechanism has simple structure and is easy to operate, the motor gear box can be controlled through electrical signals to lift and lower the windshield, the mechanism is easy to disassemble and install, the transmission precision is high, the start and stop of the motor are controlled through the current limiting substrate to reduce the system load.

[0019] Reference

[0020] Figures 1-2 ​​​​​​The present invention provides a swing-arm windshield lifting mechanism, which includes a bracket 1. The bottom inner side of the bracket 1 is connected to a bottom plate 9, and a motor gear box 8 is connected to the bottom plate 9. The left side of the bracket 1 is connected to a current limiting substrate 2. The rear wall of the bracket 1 is movably connected to the left and right sides thereof. The tops of the rear swing arm 3 and the front swing arm 6 on the same side are movably connected to a glass mounting strip 4. The bracket 1, the rear swing arm 3 and the glass mounting strip 4 are made of plastic material, and the bottom plate 9, the front swing arm 6 and the axle pressure plate 7 are made of metal material.

[0021] The output shaft of the motor gearbox 8 is connected to the front swing arm 6 and the axle pressure plate 7, respectively. The base plate 9 is a sheet metal component with angled steps stamped on either side of its center, serving as stop surfaces for the axle pressure plate's rotation. This structure makes the swing-arm windshield lifting mechanism simple and easy to operate. The windshield can be raised or lowered simply by controlling the motor gearbox 8 with electrical signals.

[0022] The rear swing arm 3 and the front swing arm 6 are movably connected to the top and bottom with a pin 5, and a plurality of pins 5 are movably connected to the bracket 1 and the glass mounting strip 4. This structure facilitates disassembly and installation.

[0023] Working Principle: This solution first installs the windshield on the glass mounting bar 4. The motor gearbox 8, when in operation, drives the front and rear swing arms to swing, causing the glass mounting bar 4 to move up and down, thereby raising and lowering the windshield. The bracket 1, rear swing arm 3, and glass mounting bar 4 are made of plastic, while the base plate, front swing arm 6, and axle pressure plate 7 are made of metal, effectively reducing the overall weight of the mechanism. This solution is simple in construction and easy to operate. Simply controlling the motor gearbox 8 via electrical signals allows for large lifting ranges, a lightweight structure, and ease of disassembly and installation. It also features high transmission precision. The motor's start and stop are controlled by the current-limiting control baseboard assembly 2, reducing system load.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
