Description

Technical Field

[0001] This utility model relates to the field of automotive cover technology, and in particular to a solar-powered sunshade car cover. Background Technology

[0002] With the rapid growth of global car ownership, the issues of sun protection and energy utilization for vehicles in high-temperature environments are becoming increasingly prominent. In summer, when vehicles parked outdoors are exposed to direct sunlight, the interior temperature rises rapidly, accelerating the aging of interior materials and damaging electronic components, and posing a safety hazard of spontaneous combustion of flammable materials. Traditional sun protection methods often use car covers made of polyester fiber or aluminum foil, which, while offering some heat insulation, have significant limitations: First, physical shielding only passively blocks some heat, and the risk of high temperatures remains after prolonged parking; second, traditional car covers require manual installation and removal, which is cumbersome and unsuitable for frequent vehicle use; third, existing solutions lack energy conversion capabilities, resulting in a waste of solar energy resources on the car roof.

[0003] In recent years, although some technologies have attempted to integrate photovoltaic modules into vehicle roofs to achieve power generation, significant shortcomings remain. For example, solar car covers cannot be folded, or they cannot generate electricity when folded. Furthermore, while foldable car covers expand the power generation area when unfolded, they lack intelligent management modules, making it impossible to monitor power generation status, battery charging and discharging efficiency, or battery removal and replacement in real time. In addition, existing devices have limited power generation capacity while the vehicle is in motion, and the installation and replacement process for energy storage batteries is complex, resulting in a poor user experience.

[0033] One embodiment of this utility model provides a solar-powered sunshade car cover, see reference. Figures 1 to 9 ,include:

[0034] The cover 1 is provided with a plurality of solar panels 11. Two adjacent solar panels 11 are rotatably connected to each other and have an unfolded state and a stacked state. The opposite sides of the solar panels 11 are provided with semiconductor crystal layers that generate electricity through the photovoltaic effect, so that they can generate electricity in both the stacked state and the unfolded state.

[0035] The power supply assembly 2 includes a power box 21 and a battery 22. The battery 22 is detachably disposed in the power box 21. The power box 21 is provided with electrodes that are electrically connected to the battery 22. The power box 21 is electrically connected to the solar panel 11.

[0036] This embodiment solves the problems of the inability to remove and replace the battery 22 in a car cover and the inability to generate electricity when the cover is folded. Multiple solar panels 11 are installed on the cover body 1, with crystalline layers for power generation on both sides of each panel. This allows the reverse side of the solar panels 11 to generate electricity even when the cover body 1 is folded and stacked, enabling the solar sunshade car cover to generate electricity in both folded and unfolded states. The battery 22 is detachably housed in a power box 21, which is electrically connected to the solar panels 11, allowing for battery 22 replacement. After the battery 22 is fully charged, another battery 22 can be used for further charging, avoiding energy waste. This solar sunshade car cover can be applied to cars, trucks, or tricycles. The folded size of the solar sunshade car cover varies depending on the application scenario to improve its utilization rate.

[0037] In this embodiment, the cover 1 is always fixed to the vehicle body. Semiconductor crystal layers are provided on both the front and back sides of the solar panel 11 so that photovoltaic power generation can be carried out on both the front and back sides of the solar panel 11. When the vehicle is moving, the solar panels 11 are in a stacked and folded state, which ensures that the vehicle's visibility is not affected and that the solar sunshade can generate electricity continuously. When the vehicle is stopped, the user can fold and rotate the solar panels 11 in the opposite direction so that the cover 1 is unfolded. The cover 1 covers the vehicle body, which not only ensures that the vehicle is not exposed to direct sunlight and reduces the temperature inside the vehicle, but also improves the overall power generation efficiency of the solar panel 11. Battery 22 is detachably installed in power box 21. Power box 21 has electrodes corresponding to the positive and negative terminals of battery 22. Power box 21 has a control board to regulate the charging voltage of battery 22. When battery 22 is installed in power box 21, battery 22 is electrically connected to power box 21. Power box 21 is electrically connected to solar panel 11, so that the power generated by solar panel 11 is delivered to power box 21 to charge battery 22. When battery 22 is fully charged, the user can remove and replace battery 22 in time to achieve continuous charging. The fully charged battery 22 can be used for subsequent pure green electricity exchange.

[0038] The solar-powered car cover of this embodiment can significantly increase power generation. Taking a mid-sized sedan as an example: its roof area is approximately 2.0-3.0 square meters. The power generation of the cover 1 in its folded state while driving is as follows: Under standard conditions, according to the power conversion formula of the solar panel 11 (length × width × conversion rate × 0.1 = power, unit is centimeters), the power is 160W (100 × 100 × 0.16 × 0.1 = 160W). Assuming 6 hours of sunshine per day, the daily power generation from the car roof is 3 * 160 * 6 = 2880 kWh. W, approximately 2.9 kWh; taking a medium-sized truck as an example: its roof area is approximately 7.6–13.8 square meters. When parked, the power generation of the canopy 1 in its extended state is: under standard conditions, according to the power conversion formula of solar panel 11 (length × width × conversion rate × 0.1 = power, unit is centimeters), the power is 160W (100 × 100 × 0.16 × 0.1 = 160W). Assuming 6 hours of sunshine per day, the daily electricity generated by the car roof is 10 * 160 * 6 = 9600W, approximately 10 kWh. The canopy 1, in its extended state, can achieve full-area power generation on the car roof, improving power generation efficiency. Generally, the power generation from the full area of ​​the car roof is 2-3 times that from just the car roof area. The reason is that the width of the electricity generated by the entire roof of a car is the same as the width of the car itself, but the length of the electricity generated by the entire roof of a car is 2-3 times that of the electricity generated by the roof. Therefore, if we calculate based on 6 hours of sunshine per day, if the electricity generated by the roof of a car is 3*160*6=2880W per day, then the electricity generated by the entire roof of a car would be between 2880*2=5760W and 2880*3=8640W. Thus, the electricity generated by the entire roof of a car is approximately between 5.8 kWh and 8.6 kWh. Similarly, the electricity generated by the entire roof of a truck is 1.5-2 times that of the electricity generated by the roof of a truck, and the electricity generated by the entire roof of a medium-sized truck is approximately 15 kWh.

[0039] Furthermore, a connector 12 is provided between two adjacent solar panels 11. The solar panels 11 rotate and unfold or fold around the connector 12. The connector 12 has a flexible circuit board embedded in it and connects to the two adjacent solar panels 11 respectively. The connector 12 is a hinge structure, a flexible shaft, or a flexible connecting strip, which enables relative rotation between the solar panels 11. The flexible circuit board is embedded inside the connector 12 and connects the circuits of the adjacent solar panels 11, ensuring the stability of the circuit connection during folding and unfolding. In this embodiment, the connector 12 is a flexible connecting strip made of soft plastic material. The upper and lower surfaces of the flexible connecting strip are designed as concave arc surfaces, and the thickness at the middle position is less than the thickness at both ends, thereby facilitating folding. The flexible circuit board is embedded between the upper and lower surfaces of the flexible connecting strip for synchronous folding or unfolding. Specifically, the connector 12 adopts a waterproof design to prevent rainwater from seeping in and affecting the normal operation of the circuit.

[0040] Furthermore, in the folded state, the solar panels 11 are stacked on the roof and / or front of the vehicle, with the reverse side of the upper solar panel 11 generating photovoltaic power. In the unfolded state, the solar panels 11 rotate and unfold to fit against the vehicle body and / or windows, and multiple solar panels 11 generate photovoltaic power. The cover 1 has a stacked state and an unfolded state, and can generate power in both states. In the first usage state, the cover 1 is only fixed to the roof or front of the vehicle. During vehicle operation, the solar panels 11 are folded relative to each other, stacked in pairs on the roof or front of the vehicle. At this time, the reverse side of the upper solar panel 11 is flipped to the upper side. Since semiconductor crystal layers are provided on both sides of the solar panel 11, the cover 1 can generate power when the vehicle is in motion. In the second usage state, as... Figure 5 The cover 1 is simultaneously fixed to both the front and roof of the vehicle. During vehicle operation, the solar panels 11 fold to the roof and front of the vehicle, generating electricity simultaneously. In the third usage state, such as... Figures 2 to 4 When the vehicle stops, the cover 1 is flipped open from its stacked state to cover the vehicle's windows, including the front window, rear window, and side windows. Specifically, the front window can be covered by the solar panel 11 located at the front of the vehicle or by the solar panel 11 located on the roof. The stacked solar panels 11 on the roof can also be flipped backward to cover the rear window and flipped left and right to cover the side windows. The solar panels 11 covering the side windows can also be further folded to adapt to the shape of the vehicle's side profile. In addition, the unfolding angle of the solar panels 11 can be automatically adjusted according to the shape of the vehicle body to ensure a close fit with the vehicle's surface.

[0041] Furthermore, the edge of the cover 1 is provided with a fixing member and a flexible protective layer. The fixing member is connected to the car body, and the flexible protective layer is in contact with and adheres to the surface of the car body. The fixing member is made of magnetic material, electrostatic adsorption material, adhesive material, or vacuum adsorption device, etc., which can be firmly adsorbed onto the roof or front surface of the car. It can be understood that the fixing member can also be a guide rail, Velcro, spring clip, or rotary lock, etc. For example, the fixing member is a guide rail, which includes a slider and a track. The track is installed on the surface of the car body, and the slider is fixed to the cover 1. The installation and position adjustment of the solar sunshade car cover are achieved by the slider sliding into the track. The flexible protective layer is made of silicone or nylon material, which is in contact with and adheres to the surface of the car body to prevent scratching the paint. In this embodiment, the cover 1 adopts a lightweight design, with a light overall weight, making it easy for users to carry and operate. The solar panel 11 is made of flexible thin-film photovoltaic material. The thin-film material has high photoelectric conversion efficiency and flexibility, and can adapt to the curvature of different parts of the car body. Specifically, the thin-film photovoltaic material can be copper indium gallium selenide (CIGS) or amorphous silicon. The solar panel 11 consists of multiple thin-film materials attached to the frame of the cover 1. Adjacent solar panels 11 are rotatably connected by connectors 12. The edges of the solar panel 11 are also provided with silicone edging and waterproof strips to prevent tearing during bending and rainwater seepage.

[0042] Furthermore, in the first embodiment, the power supply assembly 2 is disposed within the vehicle body, and wires are respectively connected to the power supply box 21 and the solar panel 11. (See reference) Figure 5 and Figure 6 The power box 21 is connected to the solar panel 11 via wires. The wires are concealed, routed along gaps in the vehicle body or in dedicated cable trays to avoid exposure that could affect aesthetics and safety. The power box 21 can be fixed inside the vehicle, such as in the trunk or under the seats, to prevent rain, dust, and other external environmental factors from affecting the power assembly 2. Furthermore, fixing the power box 21 inside the vehicle facilitates battery replacement. The vehicle's interior space is also large enough to accommodate multiple batteries 22, increasing energy storage capacity. The high-power batteries 22 can also meet the user's vehicle usage and outdoor household power needs.

[0043] Furthermore, in the second embodiment, reference is made to... Figure 8The power assembly 2 is disposed on the cover 1, and the power box 21 is fixedly connected to the cover 1. In this embodiment, the power assembly 2 also includes screws 23, which connect the cover 1 and the power box 21 respectively to fix the cover 1 and the power assembly 2 relative to each other. It can be understood that the connection method between the power box 21 and the cover 1 can also be adhesive, snap-on, or adsorption. After the solar panel 11 generates electricity, it is directly stored in the battery 22 through the power box 21, avoiding losses caused by wire transmission. In this embodiment, the power assembly 2 and the cover 1 are combined to allow the solar sunshade car cover to be transferred as a whole, which is convenient to adapt to different vehicles and does not require reconnection of wires. Users do not need to unlock the vehicle and enter the vehicle when removing the battery 22, which improves the convenience of replacement. The power box 21 can be disposed on the edge or middle area of ​​the cover 1, and multiple power assemblies 2 can be disposed to distribute the weight. It should be noted that the power box 21 can also be fixed to the cover 1 by adhesive or snap-on.

[0044] Further, the power supply box 21 includes a housing 211 and a cover plate 212. The housing 211 has a chamber 2111 for installing the battery 22. Positive and negative electrodes are disposed within the chamber 2111. The cover plate 212 rotates to cover the opening of the chamber 2111. The housing 211 is mounted on the cover 1. The housing 211 can be cylindrical or cuboid. In one embodiment, such as... Figure 7 The housing 211 is cylindrical, and the chamber 2111 is located on the upper side of the housing 211. The cover plate 212 is rotatably connected to the housing 211 to open or close the opening of the chamber 2111. It is understood that the cover plate 212 can also be rotatably mounted on the side of the housing 211. A fixing mesh 213 is also provided inside the power box 21. The fixing mesh 213 is fixed relative to the inner wall of the chamber 2111 of the housing 211. The fixing mesh 213 presses the battery 22 into the chamber 2111, thereby preventing the battery 22 from shaking inside the chamber 2111. The fixing mesh 213 is made of insulating material to prevent the battery 22 from short-circuiting. Electrode contacts are provided inside the chamber 2111, corresponding to the electrodes of the battery 22. A silicone sealing ring is also provided on the edge of the cover plate 212. When the cover plate 212 is closed on the opening of the chamber 2111, the sealing ring ensures the waterproof and dustproof performance of the chamber 2111.

[0045] In another embodiment, such as Figure 9 The housing 211 is square, and the cover plate 212 is inserted into the opening of the chamber 2111. Both ends of the cover plate 212 are equipped with pivots, which are inserted into the cavity wall of the opening of the chamber 2111, allowing the cover plate 212 to rotate around the pivots to close or open the chamber 2111. Specifically, the housing 211 is also equipped with a pop-out button 214 that controls the automatic rotation of the cover plate 212 to open or close. When the user needs to remove the battery 22, pressing the pop-out button 214 controls the cover plate 212 to rotate, causing the battery 22 to pop out.

[0046] Furthermore, the power supply box 21 also includes a locking component, which is connected to both the housing 211 and the cover plate 212. The locking component is used to lock the cover plate 212. The locking component can be a mechanical lock or an electronic lock. A mechanical lock can be a structure where a latch and a latch engage and lock. By rotating the latch, the latch engages or disengages from the latch, thereby unlocking and locking. An electronic lock can be opened via a password, fingerprint, or APP control. In specific implementations, the locking component can be associated with the aforementioned pop-out button 214. When the latch is in the locked state, the pop-out button 214 cannot be pressed, thereby preventing accidental activation in the locked state.

[0047] Furthermore, the battery 22 housing also includes a driving component disposed within the chamber 2111 to drive the battery 22 out of the chamber 2111. The driving component is either an electric push rod or a spring. When the user needs to replace the battery 22, pressing the eject button 214 causes the cover 212 to rotate relative to the housing 211 to open the chamber 2111. Simultaneously, the driving component ejects the battery 22 out of the chamber 2111 for easy access. In this embodiment, the driving component is a spring extending along the installation direction of the battery 22. The spring abuts against the inner wall of the chamber 2111 and the battery 22. When the battery 22 is installed in the chamber 2111, the spring is compressed, and the battery 22 does not wobble. When the cover 212 is opened, the spring releases its elasticity and pushes the battery 22 out.

[0048] Furthermore, the power supply assembly 2 also includes a communication module fixed inside the power supply box 21. The communication module is used to connect with an external terminal and transmit data from the battery 22. The communication module is a Bluetooth, Wi-Fi, or IoT module, which can transmit information such as the battery power and charging status of the battery 22 to the user's mobile phone APP or cloud server in real time, so as to facilitate remote monitoring by the user. It should be noted that the mobile phone can at least receive information on the battery charging status, including: whether the battery is charging, whether the battery is fully charged, whether there is a charging fault in the battery, the real-time charging level of the battery, and information on the alternating charging of multiple batteries.

[0049] Furthermore, the power supply component 2 also includes a positioning module, which is used to obtain the location information of the solar-powered vehicle cover. The positioning module is a GPS or BeiDou module, capable of locating the solar-powered vehicle cover in real time to prevent loss. The location information can be uploaded to the user's mobile app via a communication module for easy retrieval.

[0050] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
