Description

Technical Field

[0001] The invention relates to the field of vehicle-mounted solar power generation, and in particular to a vehicle-mounted retractable combined solar power generation device. Background Art

[0002] The transformation and development model of new energy is a path that countries around the world are currently exploring, among which the development and utilization of solar energy is one of the models currently adopted on a large scale. How to maximize the use of solar energy is also a focus of countries around the world. After solar power generation has occupied obvious areas such as oceans, deserts, and barren mountains, other areas that can be developed are in urgent need of exploration and use to explore new paths for human energy crisis and environmental protection.

[0003] However, in cities, in rural areas, and anywhere vehicles are parked, the sun's radiation not only deteriorates the vehicle's operating environment and accelerates vehicle aging, but also causes the solar energy to be wasted and does not contribute to mankind.

[0004] In the past, the only possible locations for vehicle-mounted solar panels were the hood and roof. However, with the increasing demand for vehicle comfort, the large area of ​​the roof occupied by the skylight has limited the technical conditions for arranging solar panels on the roof. As a result, the area for vehicle-mounted solar power generation has been further compressed, and the power generation can neither meet its own charging requirements nor have other utilization value. In addition, due to limitations in charging pile technology, smart grid technology, etc., the value of vehicle-mounted solar power generation cannot be realized.

[0005] With the gradual construction and popularization of new energy charging piles, the intelligent charging, power generation, energy storage, and peak-shaving modes have made revolutionary progress. The charging, energy storage, and peak-shaving technologies of new energy vehicles are gradually incorporated into the overall planning and development of the power grid. How to expand the area of ​​on-board solar panels, not only solve the problem of sunshade when the vehicle is parked, but also provide a way to expand the use of solar energy, so that on-board solar power generation can be connected through intelligent charging piles, and then power generation, charging, energy storage, peak-shaving, etc. can be performed to create value, is the problem to be solved by the present invention.

[0006] The vehicle-mounted retractable combined solar power generation device of the present invention is not only suitable for the self-charging and power generation and grid connection functions of new energy vehicles; it can also be applied to all non-new energy vehicles that can receive solar energy outdoors, and realize the functions of vehicle sunshade parking and power generation and grid connection through the power generation panel; it can even be installed in any fixed position that can receive solar energy with a demand for recovery, and when the area is not used, it can be unfolded for power generation and grid connection when there is sufficient sunlight, and the power generation panel can be recovered when the area is used. The device of the present invention installed on the roof is mainly to expand and increase the area of ​​the vehicle-mounted solar power generation panel, increase the power generation power, and realize charging, energy storage, and grid connection through the charging pile, so that the vehicle-mounted solar power generation has utilization value. In the future, with the development and popularization of charging / grid connection / energy storage / peak regulation and other technologies of smart charging piles, the vehicle-mounted retractable combined solar power generation device will be applied in a wider range. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle-mounted retractable combined solar power generation device, which expands the area of ​​the vehicle-mounted solar power generation panel, thereby increasing the power generation power of the power generation panel, so that the vehicle-mounted solar power generation has utilization value; at the same time, the unfolded solar power generation panel is used to provide sunshade for the parked vehicle to avoid exposure to sunlight.

[0008] In order to solve the above problems, the present invention proposes the following technical solutions:

[0009] The invention discloses a vehicle-mounted power generation device, which can be installed on all vehicles that can receive solar energy, and can also be installed at a fixed position.

[0010] When installed on a vehicle, it is preferred that two devices are arranged symmetrically on the left and right sides of the roof. Due to restrictions on vehicle technical conditions, parking conditions, etc., a single device can also be arranged according to specific circumstances. The preferred arrangement refers to the position of the luggage rack of an ordinary vehicle, such as Figure 1 shown.

[0011] In the preferred installation mode, the device opening action includes:

[0012] Inward deployment, the two inward deployment brackets of each vehicle-mounted power generation device are opened to establish a solar panel deployment track, and then the solar panel is stretched and deployed to establish the B1 and B2 solar panel areas, such as Figure 2 This deployment action occupies part of the conventional roof area, and there is an air isolation layer between the solar panel and the roof, achieving the purpose of shading the vehicle.

[0013] Outward deployment, the two outward deployment brackets of each vehicle-mounted power generation device are opened to establish a solar panel deployment track, and then the solar panel is stretched and deployed to establish C1 and C2 solar panel areas, such as Figure 2As shown. Due to the height and space occupied on the left and right sides of the parked vehicle, it is necessary to decide whether to open both sides, only the left side, only the right side, or neither side, depending on the situation. The choice of this action mode can be determined manually or automatically by adding detection means.

[0014] In the combination of the above actions, different sizes of solar panel areas will be formed, thereby forming different power generation powers: minimum mode, shading mode, and maximum mode.

[0015] Minimum mode: Solar power generation area = A.

[0016] When the vehicle-mounted retractable combined solar power generation device is not unfolded, only the solar power generation panel area laid on the hood, that is, Figure 1 and Figure 2 A in the figure. The hood of an ordinary car is the only place where solar panels can be arranged by conventional pasting, etc. without affecting the vehicle's use function, but it is not widely used due to area limitations. In the technical solution of the present invention, this part of the power generation area is the minimum mode, and other modes are all additions based on this.

[0017] Shading mode: Solar power generation area = A+B1+B2.

[0018] Only the inward solar panels are deployed. Due to the limitation of the width of the roof, the maximum inward deployment area can only be the roof area. Therefore, the maximum area of ​​B1+B2 is the roof area. When deployed, the roof can be covered to achieve the vehicle sunshade function. In this mode, the solar panels on the hood and roof of the vehicle absorb solar energy to generate electricity. Figure 2 A+B1+B2.

[0019] Maximum mode: solar power generation area = A+B1+B2+C1+C2.

[0020] The situation where both the inward and outward solar panels are fully opened. In this case, when the area around the parked vehicle is open and there is no obstruction within the length of the outward bracket, the on-board power generation device receives solar energy with the largest area to generate electricity, which not only shades the vehicle but also maximizes the use of solar energy for power generation. Due to the limitation of the roof length, the maximum length of each outward-expanded bracket can only be half of the length of the device. Therefore, C1+C2 is at most the square area of ​​the length of the device. As a vehicle-mounted device, this expanded area can be greatly increased. In this mode, the solar panels on the vehicle hood, roof, and outward-expanded position absorb solar energy to generate electricity, that is, Figure 2 A+B1+B2+C1+C2.

[0021] Due to the restrictions of vehicle parking position, clearance and clear height, in addition to all the above opening methods, the outward opening mode also includes opening only the left side, opening only the right side, and neither side. At this time, the solar power generation area is between the shading mode and the maximum mode.

[0022] To achieve the above functions, the device further includes the following technical features:

[0023] Each device includes two inward-expanding brackets for installing the expansion / contraction tracks of the solar panels, which have the function of protecting the panels after being folded;

[0024] Each device includes two outward-expanding brackets for installing the expansion / contraction tracks of the solar panels, which have the function of protecting the panels after being folded;

[0025] The inward and outward deployment bracket mechanisms are preferably controlled by servo motors respectively, with limit and locking functions; manual deployment can also be used, with limit and locking functions;

[0026] A solar panel traction track is set in each bracket, and the expansion and contraction are preferably controlled by a servo motor, with limit and locking functions; manual expansion can also be used, with limit and locking functions;

[0027] The solar panel traction track is set up in two sections: a fixed section and a folding section, and the two sections are connected by a universal folding mechanism. The fixed section is used for the fixed stroke after the solar panel is retracted, and the folding section is used for the expansion / contraction stroke of the solar panel.

[0028] Under the existing technical conditions of solar panels, it is preferred to use a folding method for expansion / contraction, with limiting and locking functions; with the development of flexible solar panel technology, it can be expanded / contracted by a rolling method in the future.

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can also make several improvements and deformations without departing from the principles of the present invention. All other embodiments obtained on the basis of these improvements and deformations belong to the scope of protection of the present invention.

[0035] See also Figure 1-3 , the present invention provides a technical solution:

[0036] Figure 1 The vehicle-mounted power generation device 1 provided in an embodiment of the present invention is shown, which is installed on the roof of the vehicle. Preferably, two sets are installed in a mirror-symmetrical manner and are installed in parallel on the left and right sides of the roof.

[0037] Each vehicle-mounted power generation device mainly includes two inwardly deployable brackets 2 and two outwardly deployable brackets 3. When the power generation device is normally driven or not in use, the brackets are in a retracted state and locked.

[0038] Figure 2 The figure shows the fully opened mode of the solar panels in the preferred installation mode of the present invention, which mainly includes:

[0039] The two inward-deployable brackets 2 of each vehicle-mounted power generation device 1 are opened synchronously to establish a solar inward-deployable power generation panel support structure, and the right inward-deployable solar power generation panel B1 and the left inward-deployable solar power generation panel B2 are opened respectively, and the power generation panels occupy the space above the vehicle roof;

[0040] The two outward-expandable brackets 3 of each vehicle-mounted power generation device 1 are opened synchronously to establish a solar power generation panel support structure, and the right outward-expandable solar power generation panel C1 and the left outward-expandable solar power generation panel C2 are opened respectively, and the power generation panels occupy the parallel space above the right and left roofs of the vehicle parking position;

[0041] The solar panel A attached to the hood is the basic configuration of the vehicle, serving as the basic power generation area of ​​the solar panel.

[0042] Figure 3 The diagram shows the structure of the right vehicle-mounted power generation device 1 as an example in the preferred installation mode of the present invention. The left vehicle-mounted power generation device is mirror-symmetrical with the left vehicle-mounted power generation device and has the same structure. It mainly includes:

[0043] There are two synchronously opened inward deployment brackets 2, each with the same structure and composition. They are 2a and 2b in the figure, and the opening method is: the inward bracket expansion / contraction servo mechanism 4 operates synchronously to establish a track, and then the inward power generation panel traction servo mechanism 5 pulls the right inward deployment solar power generation panel B1 to unfold, and this action has in-place interlocking control and locking control;

[0044] There are two outward-expanding brackets 3 that are opened synchronously, and the structure and composition of each bracket are the same. They are 3a and 3b in the figure. The opening method is: the outward bracket expansion / contraction servo mechanism 7 operates synchronously to establish a track, and then the outward-expanding solar panel C1 on the right side is pulled to expand through the outward-expanding panel traction servo mechanism 6. This action has in-place interlocking control and locking control;

[0045] The synchronously-acting brackets, i.e., 2a, 2b and 3a, 3b in the figure, mainly function to undertake the storage and protection of the solar panels and to establish tracks for the deployment and retraction of the solar panels.

[0046] Furthermore, a set of tracks is provided in each bracket, mainly including:

[0047] The fixed section 8 of the traction track of the power generation panel and the folding section 10 of the traction track of the power generation panel constitute the entire stroke of unfolding and folding the solar power generation panel, which are fixed at both ends of the bracket and driven by the traction servo mechanism of the power generation panel to traction the power generation panel to extend and unfold or fold and retract;

[0048] The power generation board traction track universal joint 9 is the folding and unfolding joint of the power generation board traction track. When unfolded, it forms a straight traction track, and when retracted, it gradually folds to 90 degrees for recovery;

[0049] The power generation panel traction block 11 is a traction element for deploying or recovering the power generation panel on the track.

[0050] As described above, the specific steps of this embodiment are as follows:

[0051] The 4 inward bracket expansion / contraction servo mechanisms 4 are synchronously operated to unlock, thereby rotating the inward expansion bracket 2 90 degrees to open, so that the fixed section 8 of the power generation board traction track and the folding section 10 of the power generation board traction track form a straight track;

[0052] The inward-facing solar panel traction servo mechanisms 5 of the four inward-facing deployment brackets 2 act synchronously, and through the panel traction block 11, they respectively traction and deploy the right inward-facing solar panel B1 and the left inward-facing solar panel B2, so that the panels occupy the space above the roof, provide sunshade for the vehicle, and generate electricity in the sunshade mode, and the solar power generation area is A+B1+B2;

[0053] If the parking condition of the vehicle meets the conditions for the deployment of the outward bracket, the four outward bracket deployment / contraction servo mechanisms 7 are synchronously operated to unlock, thereby rotating the outward deployment bracket 3 90° to open, so that the fixed section 8 of the power generation board traction track and the folding section 10 of the power generation board traction track form a straight track;

[0054] The outward-facing solar panel traction servo mechanisms 6 in 3 of the 4 outward-facing brackets act synchronously, and through the panel traction block 11, they respectively traction and unfold the right outward-facing solar panel C1 and the left outward-facing solar panel C2, so that the panels occupy the parallel space above the right and left roofs of the vehicle at the parking position, and the panels generate electricity in the maximum mode, and the solar power generation area is A+B1+B2+C1+C2;

[0055] Due to the restrictions of the vehicle parking position, clearance and clear height, the outward opening form can be determined manually or automatically by adding detection means to determine the selection among the four modes of fully open, only open the left side, only open the right side, and none of them are opened. At this time, the solar power generation area is between the shading mode and the maximum mode.

[0056] During the retraction operation, the solar panels are first folded and recovered respectively through the inward power generation panel traction servo mechanism 5 and the outward power generation panel traction servo mechanism 6. After being recovered in place, the inward bracket expansion / contraction servo mechanism 4 and the outward bracket expansion / contraction servo mechanism 7 are operated to rotate and recover the inward expansion bracket and the outward expansion bracket respectively, and the power generation panel traction track folding section 10 is folded synchronously, and locked after being recovered in place.

[0057] After all solar panels are folded and locked into the device on the roof, the external wires are retracted, safety is confirmed, and the conditions for normal driving and use of the vehicle are met, and the parking power generation mode of the vehicle-mounted device is exited.

[0058] Based on the above detailed description, these and other changes can be made to the implementation or embodiments. In general, in the appended claims, the terms used should not be interpreted as limiting the claims to the specific embodiments disclosed in the specification and claims, but should be interpreted to include all possible implementations or embodiments and the full range of equivalents authorized by these claims. Therefore, the claims are not limited by this disclosure.
