Abstract
Description
Technical Field
[0001] This invention relates to the technical field of sunshade structures, specifically a concealed sunshade for the windshield of an electric vehicle. Background Technology
[0002] To prevent the interior temperature from rising due to sunlight, windshield sunshades are commonly used to block the sun from entering the vehicle. Existing windshield sunshades are all rectangular in shape and manually operated. Because their hinge is straight while the connection between the bottom of the windshield and the center console is curved, the hinge is exposed and fixed to the center console, occupying space on the upper surface and making the vehicle look unsightly. Furthermore, when open, existing manually operated windshield sunshades have hooks or other connecting parts at the top of the windshield, which can obstruct the view and compromise driving safety. Summary of the Invention
[0003] To address the aforementioned issues, this invention provides a concealed windshield sunshade for electric vehicles. Its hinge structure mimics the shape of the bottom of the windshield, allowing the sunshade to be concealed, ensuring aesthetics and eliminating the need for connectors in the windshield area, thus guaranteeing visibility in the driver's area.
[0004] A concealed sunshade for the windshield of an electric vehicle, characterized in that it comprises:
[0005] A crankshaft includes an arc-shaped inner tube, an arc-shaped outer tube assembly, and a side bracket. The arc-shaped inner tube is fitted with an arc-shaped outer tube assembly. Both ends of the arc-shaped outer tube assembly are fixedly connected to the protruding shaft ends of the side bracket via bearings and torsion springs along the length direction. The side bracket is exposed outside the arc-shaped inner tube and is fixedly connected to the corresponding end of the arc-shaped inner tube. A fixing plate is provided at the exposed end of the side bracket.
[0006] Curtain;
[0007] Electric motor;
[0008] Two guide rails with flexible shafts;
[0009] The guide rails on both sides are mounted on the inner side of the corresponding A-pillar.
[0010] The slider assemblies on both sides, each slider assembly includes a guide rail slider and an axial slider;
[0011] And a side strip, which is an arc-shaped side strip, with end caps at both ends along the length of the side strip, and the end caps having concave guide cavities;
[0012] One end of the curtain fabric along its length is fixed to the outer edge of the arc-shaped outer tube assembly, and the other end of the curtain fabric along its length is installed on the lower surface of the side strip. The axial sliders on each side are inserted into the concave guide cavity, and each guide rail slider is locked into the guide rail arrangement on the corresponding side.
[0013] The output ends on both sides of the motor are respectively connected to the guide rail flexible shafts on the corresponding sides, and the other end of the guide rail flexible shaft passes through the guide rail from bottom to top and is estimated to be the flexible shaft fixed end of the guide rail slider.
[0014] Its further features are:
[0015] An elastic rotation device is provided inside the fixed end of the flexible shaft.
[0016] The elastic rotating device is a steel ring attached to the flexible shaft body. When the motor gear rotates, it drives the flexible shaft to move through the steel ring on the shaft body.
[0017] The upper width of the curtain is equal to the upper width of the windshield, and the lower width of the curtain is equal to the length of the arc-shaped outer tube assembly, ensuring that no exposed edge of the curtain will block the side glass and side space when the curtain is closed.
[0018] When the curtain is closed, the edge strip is arranged in a shape similar to the arc-shaped outer tube assembly;
[0019] It also includes a curtain support strip, which is located at the middle of the width direction of the curtain. The curtain support strip is used to reliably support the curtain. When the curtain is closed, the curtain support strip is rolled up to the corresponding outer periphery of the arc-shaped outer tube assembly.
[0020] With the above technical solution, the crankshaft is positioned in the seam area between the windshield and the center console. The crankshaft is shaped to resemble the bottom of the windshield, allowing the windshield sunshade to be concealed and ensuring an aesthetically pleasing design. Furthermore, the motor rotates to raise the side strips, closing the curtain. When the curtain needs to be opened, the motor rotates, pulling the curtain down to open it. The crankshaft's shape, conforming to the bottom of the windshield, ensures the sunshade is concealed and maintains an aesthetically pleasing design. Additionally, there is no need for connecting parts in the windshield area, guaranteeing visibility in the driver's area. Attached Figure Description

The other end of the guide rail flexible shaft 30 passes through the guide rail from bottom to top and is fixed to the flexible shaft fixed end 53 of the guide rail slider 51.
[0037] In practice, when the curtain 90 is closed, the motor 20 rotates, driving the corresponding guide rope 30 to be wound around the winding shaft on the corresponding side of the motor 20, thereby driving the side strip 60 to rise and close the curtain; when the curtain 90 is opened, the opening action of the curtain 90 is the same as the closing action, driven by the motor.
[0038] The upper width of the curtain 90 is equal to the upper width of the windshield 100, and the lower width of the curtain 90 is equal to the length of the arc-shaped outer tube assembly 12, ensuring that no exposed edge of the curtain 90 blocks the side glass and side space when the curtain 90 is closed.
[0039] The width of the curtain 90 is set to be equal to the upper width of the windshield 100, ensuring that no exposed edge blocks the side glass and side space when the curtain is closed.
[0040] When the curtain is closed, the edge strip 60 is arranged to mimic the edge of the curtain 90 that covers the arc-shaped outer tube assembly.
[0041] In a specific implementation, it also includes a curtain support strip 110, which is located at the middle of the width direction of the curtain 90. The curtain support strip 110 is used to reliably support the curtain 90. When the curtain 91 is open, the curtain support strip 100 is rolled up to the corresponding outer periphery of the arc-shaped outer tube assembly.

Each multi-section tube 121 has an axial protruding tooth at its inner end and an axial inner groove at its outer end. The axial protruding teeth of adjacent multi-section tubes 121 mesh with the axial inner grooves of adjacent multi-section tubes. The outermost multi-section tubes 121 on both sides are meshed with end sleeves 122. Each end sleeve 122 is connected to the protruding shaft end of the side bracket 13 through a bearing 70. The side bracket 13 is fixed to both ends of the arc-shaped inner tube 11 along its length. The bottom of the exposed end of the side bracket 13 is a fixing plate 131. The fixing plate 131 is provided with a connecting hole. Fasteners are fixed to the gap between the front end of the central control and the windshield 100 through the connecting hole. In specific implementation, a torsion spring 80 is also provided between the inner cavity of the integral structure composed of multi-section tubes 121 and the side bracket 13. The torsion spring 80 is used for winding when the curtain is open.
[0043] Serial number 1 is the overall serial number of the front windshield sunshade.
[0044] Its working principle is as follows: The crankshaft is located in the seam area between the windshield and the center console. The overall crankshaft structure is designed to mimic the shape of the bottom of the windshield, allowing the windshield sunshade to be hidden and ensuring an aesthetically pleasing design. The motor rotates to raise the side strips, closing the curtain. When the curtain needs to be opened, the motor rotates to pull the curtain down and open it. The crankshaft's shape mimics the bottom of the windshield, allowing the windshield sunshade to be hidden and ensuring an aesthetically pleasing design. Furthermore, it eliminates the need for connectors in the windshield area, ensuring good visibility for the driver.
