DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-4 As shown, a front windshield multifunctional sunshade includes: a curtain frame 100; a roller tube, which is rotatably installed in the curtain frame 100, and the roller tube is provided with a curtain 200 that extends or retracts as the roller tube rotates; when the curtain 200 is unfolded, the end away from the roller tube is a free end 210, and the travel position of the free end 210 includes a first position and a second position, when the free end 210 is in the first position, the curtain 200 is in a drooping state that can be projected, and when the free end 210 is in the second position, the curtain 200 is in an inclined state that can provide shade.

[0031] The curtain frame 100 is installed inside the vehicle roof as the basic supporting structure of the sunshade curtain, and the curtain frame 100 is fixedly connected to the roof. The roller tube can be rotatably installed in the curtain frame 100, and the rotation of the roller tube controls the unfolding and retraction of the curtain 200. The curtain 200 has a specially designed dual function. One side of the curtain 200 can reflect light for projection; the other side of the curtain 200 is used for sunshade. One end of the curtain 200 is connected to the roller tube, and the other end is a free end 210. The free end 210 can swing relative to the roller tube to adjust the inclination angle of the curtain 200.

[0032] In actual use, the user can manually change the position of the free end 210 to swing it to the first position or the second position. When the free end 210 is in the first position, the curtain 200 unfolds and droops, which is suitable for screen projection, because the surface of the curtain 200 is flat and suitable for projection; when the free end 210 is in the second position, the curtain 200 tilts and fits perfectly with the curvature of the front windshield, forming a certain angle to block the sunlight and achieve a sunshade effect. A multifunctional front windshield sunshade is provided, which can be used for sunshade and as a screen projection cloth, and is easy to use. The design of this sunshade is convenient and practical. It can be freely switched between the two functions of sunshade and screen projection through simple operation, which improves the convenience and entertainment of vehicle use.

[0033] On the basis of the above embodiment, one side of the curtain 200 is set as a curtain surface 240 that can reflect light. This design allows the curtain 200 to play an additional role in a specific position - acting as a projection screen. When the curtain 200 is unfolded to the point where its free end 210 is in the first position, that is, the curtain 200 is completely drooped, the curtain surface 240 forms an ideal projection interface. Due to its good light reflection performance, images can be projected onto it from the projection equipment inside the vehicle, realizing in-vehicle movie watching or other entertainment and office needs.

[0034] This design not only makes full use of the space of the sunshade, but also eliminates the need to install an additional fixed projection screen, saving costs and space, and improving the integration and versatility of the in-vehicle facilities. At the same time, the curtain 200 achieves a dual-purpose effect, avoiding unnecessary space occupation, making the entire design both practical and flexible.

[0035] like Figure 1-4 As shown, on the basis of the above embodiment, the free end 210 of the curtain fabric 200 has an edge strip 220 , and the edge strip 220 is provided with a first connecting portion 230 .

[0036] Preferably, the first connection portion 230 is configured as a buckle or a magnetic member. A connection seat 400 is provided on the dashboard of the vehicle, and when the free end 210 is in the second position, the first connection portion 230 can be detachably connected to the connection seat 400, which means that the user can easily fix the free end 210 in the second position, that is, ensure that the curtain 200 remains in a tilted state for sunshade. For example, when the curtain 200 is set to a tilted state for sunshade (that is, the free end 210 is in the second position), the first connection portion 230 can be firmly connected to a preset fixed point inside the vehicle (such as the connection seat 400 on the dashboard) through a buckle or magnetism, thereby effectively blocking the sunlight.

[0037] Similarly, when the curtain 200 needs to be adjusted to the projection state or rolled back onto the reel, the user can easily disassemble the first connecting portion 230 from the connecting seat 400, so that the free end 210 leaves the second position. Such a design is convenient and fast, and improves the user experience and the versatility of the vehicle.

[0038] like Figure 1-3 As shown, based on the above implementation, it further includes a motor 300, the motor 300 is linked to the winding tube, and the stroke position of the winding tube is determined by the stroke position of the motor 300.

[0039] In this embodiment, a motor 300 component is added to realize automatic control, which significantly improves the convenience of use. The motor 300 is directly linked to the roller tube and plays a core role in controlling the extension of the curtain 200. This means that the travel position of the roller tube is no longer manually adjusted, but is automatically adjusted by the motor 300 according to the received instructions, thereby determining the extension degree and final position of the curtain 200.

[0040] On the basis of the above-mentioned embodiment, the motor 300 is connected to the driving gear 310, and the reel is connected to the driven gear 320, and the driving gear 310 meshes with the driven gear 320. When the motor 300 rotates, the driving gear 310 also starts to rotate. The teeth of the driving gear 310 mesh with the driven gear 320 on the reel to form a stable transmission chain, which efficiently and losslessly transmits the power of the motor 300 to the reel. As the reel rotates, the curtain 200 inside the reel also stretches, so the motor 300 plays a role in driving the curtain 200 to unfold.

[0041] On the basis of the above embodiment, a return torsion spring is arranged in the roller tube, one end of which is connected to the roller tube and the other end is connected to the curtain frame 100. The return torsion spring mainly provides power for the retraction of the curtain 200. When the motor 300 rotates in the reverse direction, the roller tube rotates in the reverse direction under the drive of the return torsion spring, thereby rolling up the curtain 200. Thus, the effect of automatically opening or rolling up the curtain 200 is achieved.

[0042] like Figure 1-6 As shown, a vehicle includes a front windshield multifunctional sunshade, a roof 500 and a front windshield. The front windshield multifunctional sunshade is installed in the roof 500. The roof 500 is provided with strip holes for the curtain 200 to enter and exit. When the curtain 200 is unfolded and the free end 210 is in the second position, the curtain 200 covers the front windshield.

[0043] This design perfectly combines sunshade with the intelligent needs of modern vehicles. In the structural layout of the vehicle, the front windshield multifunctional sunshade is installed inside the canopy 500 on the top of the vehicle. This design does not take up extra space and ensures harmony with the interior decoration of the vehicle. The canopy 500 is specially provided with strip holes to facilitate the smooth entry and exit of the curtain 200. When it is needed, the curtain 200 can be easily unfolded, and when it is not needed, it can be neatly stored in the canopy 500 without affecting the beauty of the vehicle.

[0044] When the curtain 200 is unfolded, the free end 210 of the curtain 200 is in the first position, and the curtain 200 is in a naturally drooping state, and can be used as a projection screen. When sunshade is needed, the free end 210 of the curtain 200 can be pushed to the second position, and the curtain 200 is in an inclined state, just matching the angle of the front windshield. This position design is ingenious so that the curtain 200 can cover the entire front windshield, effectively blocking strong direct sunlight and reducing the temperature rise in the car.

[0045] On the basis of the above embodiment, it also includes a dashboard, which is provided with a connecting seat 400, and the connecting seat 400 is hinged with an openable and closable connecting panel 410, and the connecting panel 410 has a second connecting portion 411; when the connecting panel 410 is in an open state and the free end 210 is in the second position, the first connecting portion 230 of the edging strip 220 and the second connecting portion 411 of the connecting panel 410 are detachably connected to keep the curtain 200 in an inclined state.

[0046] A connection panel 410 for sucking the free end 210 is specially provided on the instrument panel. The connection panel 410 is provided with a second connection portion 411. After the connection panel 410 pops up, the first connection portion and the second connection portion 411 can form a detachable connection structure.

[0047] In the specific structure, one of the first connection part 230 and the second connection part 411 is set as a magnet and the other is set as a ferromagnetic component, or both are magnets, and the connection panel 410 can be opened or closed. When the connection panel 410 is closed, it is flush with the surface of the dashboard; when the connection panel 410 is opened, it flips upward. At this time, when the free end 210 is in the second position, the first connection part 230 on the free end 210 and the second connection part 411 of the connection panel 410 are attracted by magnetic force. At this time, the free end 210 of the curtain 200 can be firmly fixed on the connection panel 410 of the dashboard, keeping the curtain 200 unchanged at the preset inclination angle.

[0048] On the basis of the above embodiment, the connecting seat 400 is installed with a push-type lock 420, and a driving torsion spring is sleeved on the hinge shaft between the connecting panel 410 and the connecting seat 400. When the connecting panel 410 is in a closed state, the push-type lock 420 locks the connecting panel 410. When the connecting panel 410 is pressed, the push-type lock 420 is unlocked and the connecting panel 410 pops up under the action of the driving torsion spring.

[0049] The push-type lock buckle 420 is an existing lock buckle structure, which is often used in automobile storage boxes. Its feature is that it can be unlocked by pressing. In the actual structure, the connection panel 410 is hinged to the connection seat 400, and the hinge axis between the two has a driving torsion spring for opening the connection panel 410. When the connection panel 410 is closed, the push-type lock buckle 420 locks the connection panel 410, thereby limiting the connection panel 410 from automatically opening. At this time, the connection panel 410 is flush with the vehicle's instrument panel. When the connection panel 410 needs to be opened, it only needs to press the connection panel 410 to unlock the push-type lock buckle 420, and the connection panel 410 automatically pops up to the open state under the action of the driving torsion spring.
