Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive parts technology, specifically to a foldable roof device for automobiles that can be installed on the roof rack, is capable of being flipped and folded up, and generates electricity. Background Technology
[0002] When a car is parked outdoors, prolonged exposure to direct sunlight can cause the interior temperature to rise sharply (reaching 60℃~80℃ in summer), accelerating interior aging and fading, affecting driving and riding comfort, and increasing air conditioning energy consumption. Furthermore, sudden rain can also wet the car body, impacting the user experience. Currently, the main types of car sun protection and rain protection products available on the market include: (1) Umbrella-style sunshade: The sunshade is spread out above the vehicle roof through a central support rod and umbrella rib structure. This method requires a central support, occupies a large space, has poor wind resistance, and can only cover the area above the vehicle roof, with limited side sun protection effect. (2) Car cover-style sunshade: It needs to cover the entire car body, which is cumbersome to use and is easily blown away by strong winds, making it inconvenient to fix. (3) Fully automatic remote control car roof sunshade: It automatically unfolds and retracts through an electric mechanism. It has a complex structure and high cost (market price is usually in the hundreds to thousands of yuan). The electric components are prone to failure when exposed to the outdoors for a long time. (4) Rooftop canopy / side tent: mostly used in camping scenarios, requires additional support poles and ropes for fixation, not suitable for daily parking for sun protection and rain protection. The aforementioned existing products generally suffer from the following shortcomings: complex structure or reliance on external support, inconvenient folding and storage, unsatisfactory integrated sun protection and rain protection effect, and unsuitability for high-frequency daily use. Therefore, there is a need for a car sunshade and rainproof folding canopy device that is simple in structure, easy to operate, compact in folding, has good sun and rain protection effect, and is suitable for daily use. Summary of the Invention
[0003] The purpose of this invention is to provide a car sunshade and rainproof folding canopy that generates electricity, solving the problems of existing car sunshade and rainproof devices being complex in structure, inconvenient to fold, and having unsatisfactory sunshade and rainproof effects. To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A car sunshade and rainproof power-generating folding roof consists of a front frame, a rear frame, a single piece of sunshade and rainproof fabric, and a roof rack fixing device. The rear frame is directly fixedly installed on the car roof rack, and the front frame is hinged to the rear frame via a hinge. The front frame can be flipped forward and backward around the hinge point. The front frame includes a front panel frame and a left wing frame and a right wing frame respectively hinged to the left and right sides of the front panel frame. The rear frame includes a rear panel frame and a left wing frame and a right wing frame respectively hinged to the left and right sides of the rear panel frame. The entire piece of sun-proof and rain-proof fabric covers and is fixed to the front frame and the rear frame; The roof rack fixing device is a structure that combines clips and screws, used to fix the rear frame to the car roof rack. Furthermore, after the front frame is hinged to the rear frame, it can be flipped forward and unfolded to be on the same horizontal plane as the rear frame, forming a complete roof covering plane; when folded up, the front frame flips backward and folds over the rear frame, forming a compact whole with the rear frame. Furthermore, the left and right wing frames of the front frame are respectively hinged to the left and right sides of the front panel frame, and can be flipped outward around the hinge to be on the same horizontal plane as the front panel frame, or flipped inward and folded over the front panel frame. Furthermore, the left and right wing frames of the rear frame are respectively hinged to the left and right sides of the rear panel frame, and can be flipped outward around the hinge to be on the same horizontal plane as the rear panel frame, or flipped inward and folded over the rear panel frame. Furthermore, each hinge edge is provided with 2 hinges, for a total of 10 hinges: 2 on the middle horizontal hinge edge, 2 on each of the left and right hinge edges of the front panel, and 2 on each of the left and right hinge edges of the rear panel. Furthermore, once unfolded, the front frame, rear frame, and all side wing frames are on the same horizontal plane. The sunshade and rainproof cloth is flattened by the frame and suspended above the roof. No additional support rods or support legs are needed; the unfolded state is maintained entirely by the rigidity of the frame itself. Furthermore, the sun-protective and rain-proof fabric is a single piece of flexible material that covers all the independent frames and can be bent at the hinge joints as the frames are folded. Furthermore, the front frame and the rear frame, when unfolded, form a planar covering structure with a coverage area larger than the roof area of the car, extending to all four sides of the roof. Furthermore, the left and right wing frames of the front and rear frames remain horizontal after unfolding, and the sun-proof and rain-proof cloth at their edges can hang vertically downward to form a side shielding structure, which is used to shield the side windows and doors of the vehicle body to achieve the side sun-proof and rain-proof effect. Furthermore, the sun-proof and rain-proof fabric at the edge of the side frame extends beyond the frame edge, and the extended portion of the fabric can hang down naturally to form a vertical shielding surface. Beneficial effects The beneficial effects of this invention are as follows: (1) Simple and reliable structure: pure mechanical hinge structure, no electric, hydraulic or pneumatic parts, not easy to fail, long service life and low maintenance cost. (2) Integrated sun protection and rain protection: A single piece of sun protection and rain protection fabric provides seamless coverage without any seams. Rain protection will not leak from the seams, and sun protection will not leak through any gaps. The protective effect is better than that of segmented splicing products. (3) Folding compactly: After being folded up, all the frames are folded into a compact whole and directly fixed to the roof rack. It does not occupy the trunk space and does not affect the normal driving and aesthetics of the vehicle. (4) Easy to operate: The unfolding and folding actions are simple and intuitive, and the book-flipping folding logic allows users to complete the operation quickly. (5) No additional support required: After unfolding, the frame itself is rigidly suspended and maintains the unfolded state without the need for support rods, ropes or other auxiliary fixing devices. (6) High versatility: It is fixed to the roof rack by clips and screws, and is compatible with most vehicles equipped with roof racks (roof racks). (7) Expandable power generation function: The sun protection and rain protection cloth can be replaced with solar panel components. By using rigid or semi-rigid small solar panels to be laid in sections and flexible encapsulation connecting pieces for transition, the power generation, sun protection and rain protection can be achieved in one while retaining the folding function. The generated electricity can be used by vehicle-mounted equipment.

Detailed Implementation The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1 like Figure 1 As shown, this embodiment provides a car sunshade and rainproof power-generating folding roof, which consists of a front frame, a rear frame, a single piece of sunshade and rainproof fabric 40, and a roof rack fixing device 50. I. Overall Structure The folding canopy consists of a front frame 10, a rear frame 20, a single piece of sun-proof and rain-proof fabric 40, and a roof rack fixing device 50. The front frame 10 and the rear frame 20 each contain three sub-frames, which, when unfolded via hinges, form a 2-row × 3-column overall layout. Front frame 10: includes front panel frame 11, front panel left wing frame 12 and front panel right wing frame 13. Front panel left wing frame 12 is hinged to the left side of front panel frame 11 by two hinges (second hinge group 32), and front panel right wing frame 13 is hinged to the right side of front panel frame 11 by two hinges (third hinge group 33). Rear frame 20: includes rear panel frame 21, rear panel left wing frame 22 and rear panel right wing frame 23. The rear panel left wing frame 22 is hinged to the left side of the rear panel frame 21 by two hinges (fourth hinge group 34), and the rear panel right wing frame 23 is hinged to the right side of the rear panel frame 21 by two hinges (fifth hinge group 35). Front and rear connection: The front frame 10 is hinged to the rear frame 20 by two hinges (first hinge group 31), and the hinge edge is located between the rear side of the front panel frame 11 and the front side of the rear panel frame 21. There are a total of 10 hinges, with 2 hinges on each hinge side to ensure hinge stability and smooth flipping. II. Sunscreen and rainproof fabric The sun- and rain-proof fabric 40 is a single piece of flexible material (such as a sun- and rain-proof coated fabric) that covers and secures the top of all six independent frames. At the hinge joints, the fabric can naturally bend as the frames are flipped and folded. The entire piece of fabric is seamlessly spliced, ensuring both waterproof and sun-protective effects. III. Roof rack fixing device The roof rack fixing device 50 is located at the bottom of the rear panel frame 21 of the rear frame 20, and includes a buckle 51 and a screw 52. The buckle 51 is fastened to the crossbar of the roof rack 60, and the screw 52 is used to tighten it, so as to achieve a firm connection between the rear frame 20 and the roof rack 60. IV. Development Process To expand, follow these steps: Step 1: Flip the front frame 10 forward. Flip the front frame 10 forward around the hinge axis of the first hinge group 31 until the front panel frame 11 and the rear panel frame 21 are on the same horizontal plane, forming a complete roof covering plane. Step 2: Unfold the side wings of the front frame 10. Flip the left wing frame 12 of the front panel outward around the second hinge group 32 until it is on the same horizontal plane as the front panel frame 11; flip the right wing frame 13 of the front panel outward around the third hinge group 33 until it is on the same horizontal plane as the front panel frame 11. Step 3: Unfold the side wings of the rear frame 20. Flip the left wing frame 22 of the rear panel outward around the fourth hinge group 34 until it is on the same horizontal plane as the rear panel frame 21; flip the right wing frame 23 of the rear panel outward around the fifth hinge group 35 until it is on the same horizontal plane as the rear panel frame 21. Once deployed, the front frame 10, rear frame 20, and all side frames are on the same horizontal plane. The sunshade and rainproof fabric 40 is flattened by the frames, forming a complete sunshade and rainproof canopy that hangs over the roof and surrounding areas of the vehicle. The deployed canopy is held in place entirely by the rigidity of the frames themselves, requiring no additional support rods or legs. The left and right side wing frames remain horizontal after deployment, but the sun-protective and rain-proof fabric 40 at the edges of the side wing frames extends beyond the frame edges and can hang vertically downwards to form a side shielding structure. This vertical shielding surface can effectively cover the side windows and doors of the vehicle body, achieving side sun and rain protection. V. Collapse Process To collapse the operation, follow these steps: Step 1: Fold all side wings together. Flip the left and right side wing frames 12 and 13 of the front panel inward and fold them over the front panel frame 11; flip the left and right side wing frames 22 and 23 of the rear panel inward and fold them over the rear panel frame 21. Step 2: Fold the front frame. Flip the front frame 10 around the first hinge group 31 backward so that the front panel frame 11 overlaps the back panel frame 21. Once retracted, the front frame 10, the rear frame 20, and all side wing frames are stacked into a compact whole and fixed to the roof rack, without affecting the normal driving of the vehicle. VI. Usage Scenarios This product is suitable for sedans, SUVs, MPVs, and other vehicles equipped with roof racks (roof racks). It can be unfolded for use when parking to protect against sun and rain; it can be folded up and securely fixed to the roof rack before driving. Example 2 Based on Example 1, the sun-protective and rain-proof cloth 40 can be replaced with a solar panel assembly. The solar panel assembly includes multiple small solar panels, one of which is fixed to each independent frame. Adjacent small solar panels are connected by flexible encapsulation connecting pieces. When the frame is folded using hinges, the flexible encapsulation connecting pieces bend accordingly, while the small solar panels themselves do not bend, thus protecting the structural integrity and power generation efficiency of the small solar panels. Specifically, the solar panels are rigid or semi-rigid solar cells with a conversion efficiency of over 20%, and are fixed above six independent frames. Adjacent solar panels are connected by flexible encapsulation connectors (such as flexible EVA encapsulation film or flexible silicone connectors) and electrically connected in series via flexible wires. In the unfolded state, all solar panels and the flexible encapsulation connectors together form a complete solar power generation surface, achieving the triple functions of power generation, sun protection, and rain protection. The electrical energy generated by the solar panel assembly is transmitted to an external energy storage device (such as a vehicle battery) via flexible wires to charge in-vehicle electronic devices or for other purposes. By replacing the sun-protective and rain-proof cloth with solar panel components, this embodiment retains all the folding functions of Embodiment 1 and adds solar power generation function, realizing the three-in-one effect of power generation, sun protection and rain protection, further improving the practical value and energy utilization rate of the product.
