Description

Technical Field

[0001] This application relates to the technical field of automobiles, and particularly to an in-vehicle solar charging system and a vehicle. Background Art

[0002] With the progress of industrial technology and the improvement of social environmental protection awareness, the application scenarios of new energy vehicles are increasing day by day. The user demands for driving new energy vehicles for outdoor activities, self-driving tours, etc. are also becoming more and more vigorous, and the requirements for vehicle energy storage and power consumption are also increasing day by day. At present, the electric energy stored in vehicles often cannot meet the demands for electric energy during long-term driving and outdoor activities.

[0003] In recent years, with the rapid development of the solar cell technology industry, the efficiency of solar cells has been gradually climbing, and the idea of combining solar cells with new energy vehicles has gradually come into the sight of major automobile manufacturers. Using solar cells to assist in charging in-vehicle batteries anytime and anywhere can increase the driving range of vehicles and relieve the mileage anxiety of drivers.

[0004] At present, most solar vehicles directly install independent photovoltaic panels on the vehicle roof. This method not only increases the vehicle body weight but also affects the vehicle appearance. There are also some solar vehicles that use flexible solar cells instead of photovoltaic panels. Utilizing the rollability of flexible solar cells, when the flexible solar cells are not in use, they can be curled up and placed on the vehicle roof, which can minimize the impact of solar cells on the vehicle weight and appearance. However, whether it is a photovoltaic panel or a flexible solar cell, it is inevitable that they will be exposed outside the vehicle when not in use, which will not only affect the vehicle appearance but also cause the solar cells to be impacted by rain, snow and other weather when the vehicle encounters such weather. In the long run, it will damage the solar cells and reduce the service life of the solar cells. Summary of the Utility Model

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] The solar cells of existing solar cars are usually exposed outside the vehicle, resulting in the solar cells being impacted by rain, snow and other weather when the vehicle encounters such weather. Over time, it will cause damage to the solar cells and reduce the service life of the solar cells.

[0034] To solve the above problems, the embodiment of the present utility model provides a vehicle-mounted solar charging system, which is arranged on the roof 100 of the vehicle and includes:

[0035] A storage structure 1, which includes a storage groove 101 arranged on the roof 100 and a movable groove door 102 for covering or opening the storage groove 101;

[0036] A solar device 2, which includes a lifting support structure 201 arranged in the storage groove 101, a reel 202 arranged on the lifting support structure 201, and a flexible solar cell 203 that can be wound on the reel 202 and can be unfolded along the reel 202; wherein,

[0037] The flexible solar cell 203 is used to convert light energy into electrical energy and store the electrical energy in the energy storage device of the vehicle to charge the energy storage device;

[0038] The lifting support structure 201 is used to drive the reel 202 to lift along the storage groove 101, so that the flexible solar cell 203 on the reel 202 is stored in the storage groove 101 or extends above the storage groove 101.

[0039] When the vehicle-mounted solar charging system provided by the embodiment of the present utility model needs to assist in charging the vehicle through a solar cell, first open the movable slot door 102 to expose the storage slot 101, and then start the lifting support structure 201. The lifting support structure 201 lifts the reel 202 and the flexible solar cell 203 wound on the reel 202 above the storage slot 101. After that, the flexible solar cell 203 is unwound along the reel 202 and laid flat on the vehicle roof 100. At this time, the flexible solar cell 203 can convert the sunlight irradiated on the vehicle roof 100 into electric energy and store it in the energy storage device of the vehicle, so as to achieve the purpose of charging the energy storage device. After charging, the flexible solar cell 203 is rewound by using the reel 202, and then the lifting support structure 201 is started. The lifting support structure 201 lowers the reel 202 and the flexible solar cell 203 wound on the reel 202 into the storage slot 101, and then closes the movable slot door 102, so as to achieve the purpose of storing the solar cell.

[0040] Based on the above, for the vehicle-mounted solar charging system according to the embodiment of the present utility model, by providing a storage slot 101 on the vehicle roof 100 and a movable slot door 102 that can cover and open the storage slot 101, and driving the lifting of the flexible solar cell 203 along the storage slot 101 through the lifting support structure 201, the user can extend the flexible solar cell 203 above the storage slot 101 and unfold it for charging according to the need, meeting the user's need for auxiliary charging of the vehicle through the solar cell, alleviating the user's range anxiety, and also completely storing the flexible solar cell 203 in the storage slot 101 and covering and protecting it through the movable slot door 102 after charging, minimizing the impact of the solar charging system on the appearance and safety of the vehicle, and effectively reducing the risks such as aging and damage of the solar cell caused by the long-term exposure of the solar cell outside the vehicle, and prolonging the service life of the solar cell.

[0041] The vehicle-mounted solar charging system provided by the embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0042] According to Figure 1 Exemplarily showing the vehicle-mounted solar charging system of at least one embodiment of the present utility model, the vehicle-mounted solar charging system is provided on the vehicle roof of a vehicle, and it includes: a storage structure 1 and a solar device 2.

[0043] Such as Figure 1As shown in the figure, the storage structure 1 specifically includes a storage groove 101 and a movable groove door 102. Among them, the storage groove 101 is a groove opened on the vehicle roof 100 and recessed downward to form a storage space on the vehicle roof 100 for storing the solar device 2. The movable groove door 102 is movably arranged on the vehicle roof 100 and is used to cover or open the storage groove 101, so as to provide protection for the solar device 2 stored in the storage groove 101, avoid the influence of dust, particulate matter, rain, snow, etc. in the surrounding environment on the solar device 2, and extend the service life of the solar device 2.

[0044] Specifically, in this embodiment, the storage groove 101 may be a strip-shaped groove extending along the length direction or the width direction of the vehicle on the vehicle roof 100. Refer to Figure 4 and Figure 5 , preferably in this embodiment, the storage groove 101 extends along the width direction of the vehicle. It can not only reduce the length of the storage groove 101 and reduce the impact on the vehicle itself caused by grooving, but also, since the vehicle roof 100 is usually horizontal in its width direction, it can reduce the processing difficulty of the storage groove 101. In addition, the storage groove 101 arranged along the width direction of the vehicle also provides a basis for the flexible solar cell 203 to unfold along the length direction of the vehicle, which is beneficial to the flexible solar cell 203 covering the entire vehicle body and providing a sunshade effect for the vehicle.

[0045] Furthermore, the length of the storage groove 101 is slightly smaller than the width of the vehicle roof 100, so that the flexible solar cell 203 extending outward from the storage groove 101 can basically cover the vehicle roof 100 in the width direction. This can not only increase the unfolding area of the flexible solar cell 203 and improve the power generation efficiency, but also cover the vehicle roof 100 more comprehensively and provide a better sunshade effect for the top of the vehicle.

[0046] Even further, in this embodiment, the storage groove 101 may be arranged at the front end, the rear end or a position between the two of the vehicle roof 100. Specifically, when the solar device 2 only includes one flexible solar cell 203, preferably the storage groove 101 is arranged at the front end or the rear end of the vehicle roof 100. In this way, when the flexible solar cell 203 extends outward from the storage groove 101, it can at least cover the entire vehicle roof 100 to ensure that the flexible solar cell 203 has a large unfolding area; and when the solar device 2 includes two or more flexible solar cells 203, the storage groove 101 can be arranged at the front end, the rear end or a position between the two of the vehicle roof 100. In this way, when the two flexible solar cells 203 extend forward and backward respectively from the storage groove 101, the combination of the two flexible solar cells 203 can at least cover the entire vehicle roof 100 and cover the entire vehicle body when needed, ensuring that the flexible solar cell 203 has a large unfolding area. For example, Figure 4 and Figure 5An exemplary embodiment of the storage groove 101 disposed at the middle position of the vehicle roof 100 is shown.

[0047] See Figure 1 and Figure 2 , in this embodiment, the movable slot door 102 can at least cover the storage groove 101. For example, the movable slot door 102 is a strip-shaped plate member matching the shape of the slot opening of the storage groove 101, and its length and width are equal to or slightly larger than the length and width of the slot opening of the storage groove 101, so that when the movable slot door 102 covers the storage groove 101, the appearance of the vehicle top is the same as that of an ordinary vehicle top, ensuring the beauty of the vehicle appearance and having no impact on the streamline design of the vehicle top.

[0048] Furthermore, in this embodiment, the movable slot door 102 is movably installed on the vehicle roof 100 and is electrically controlled by the vehicle central control. Specifically, the movable slot door 102 can be controlled to open and close by an opening and closing structure (not shown in the figure) built into the vehicle roof 100. For example, the opening and closing structure for controlling the movable slot door 102 can specifically select the opening and closing structure of an electric built-in sunroof on an existing vehicle, and its specific structure will not be elaborated in this embodiment. Generally speaking, the opening and closing structure is controlled by the vehicle central control, powered by a driving motor, and driven through a transmission component, so that the movable slot door 102 can move from the storage groove 101 to the inside of the vehicle roof 100 to be hidden, and move from the inside of the vehicle roof 100 to the storage groove 101 to cover the storage groove 101.

[0049] Furthermore, in this embodiment, a sealing structure (not shown in the figure) is also provided between the movable slot door 102 and the storage groove 101 to seal the slot opening of the storage groove 101 when the movable slot door 102 covers the storage groove 101, avoiding external dust, rainwater, etc. from entering the storage groove 101 and providing better protection for the solar device 2. For example, the sealing structure can include a sealing strip disposed on the outer contour of the movable slot door 102. When the movable slot door 102 covers the storage groove 101, the sealing strip on the movable slot door 102 is pressed and fitted with the slot opening of the storage groove 101 to achieve sealing.

[0050] In some embodiments, in order to avoid water accumulation in the storage groove 101, drainage holes can also be provided in the storage groove 101. The drainage holes can be directly opened at both ends of the storage groove 101, so that the rainwater seeping into the storage groove 101 can be directly discharged outward from both ends of the storage groove 101; of course, the drainage holes can also be connected to the internal drainage system of the vehicle itself, so that the rainwater seeping into the storage groove 101 is discharged through the drainage system. For example, the drainage system can include a drain pipe disposed in the vehicle B-pillar and extending from the vehicle roof 100 to the vehicle bottom.

[0051] See Figure 1, in this embodiment, the solar energy device 2 is disposed in the storage groove 101, and specifically includes a flexible solar cell 203, a reel 202, and a lifting support structure 201.

[0052] Among them, the flexible solar cell 203 is used to convert light energy into electrical energy and store the electrical energy in the energy storage device of the vehicle to charge the energy storage device. Specifically, the flexible solar cell 203 can be an existing rollable solar thin film battery, which is light in weight, can reduce the impact of the added solar cell on the vehicle body weight, and can also be rolled up for storage to reduce the impact of the added solar cell on the vehicle appearance.

[0053] Furthermore, in this embodiment, the flexible solar cell 203 is specifically selected as a perovskite solar thin film battery. The conversion efficiency of the perovskite tandem cell based on N-type TOPCon reaches 33.24%, which is much higher than 17.26% and 24% of the cadmium telluride solar cell, and can improve the power generation efficiency of the solar cell.

[0054] In this embodiment, the reel 202 is used to wind up the flexible solar cell 203 to facilitate the storage and extension of the flexible solar cell 203. For example, the flexible solar cell 203 is wound around the reel 202, and a winding mechanism is provided on the reel 202. The winding mechanism includes a volute spring (not shown in the figure) disposed between the flexible solar cell 203 and the reel 202. The inner end of the volute spring is fixedly connected to the reel 202, and the outer end of the volute spring is connected to the inner end of the flexible solar cell 203. In this way, the automatic winding of the flexible solar cell 203 can be realized by using the volute spring, and the operation is more convenient.

[0055] In this embodiment, the lifting support structure 201 is used to install and support the reel 202 and drive the reel 202 to lift along the storage groove 101, so that the flexible solar cell 203 on the reel 202 descends into the storage groove 101 or extends above the storage groove 101, facilitating the storage and unwinding of the flexible solar cell 203.

[0056] Specifically, referring to Figure 1 and Figure 3 , the lifting support structure 201 includes a driver 2011 and a support frame. Among them, the driver 2011 is fixedly installed inside the storage groove 101 and is used to realize the lifting drive in the vertical direction. For example, the driver 2011 can adopt existing electric push rods, hydraulic cylinders, etc. In this embodiment, the driver 2011 specifically includes two electric push rods, and the two electric push rods are distributed at both ends inside the storage groove 101 and are both electrically controlled by the vehicle central control.

[0057] Referring to Figure 3, the support frame includes a crossbar 2012 and two vertical rods 2013 fixed to both ends of the crossbar 2012. Among them, the crossbar 2012 is horizontally and fixedly installed at the upper ends of the telescopic rods of two electric push rods, and the reel 202 is horizontally fixed between the two vertical rods 2013 at both ends of the support frame, so that the flexible solar cell 203 wound on the reel 202 can be supported by the support frame and driven to lift by the driver 2011.

[0058] Furthermore, referring to Figure 1 , in this embodiment, there are two rolls of flexible solar cells 203. Correspondingly, there are also two reels 202. The two rolls of flexible solar cells 203 are respectively wound around the two reels 202, and the winding directions of the two rolls of flexible solar cells 203 are opposite. Correspondingly, referring to Figure 1 , there are also two sets of support frames. The two sets of support frames are connected by a connecting rod (not labeled in the figure) and fixed to the driver 2011. With this setting, the two rolls of flexible solar cells 203 can extend towards the front and rear of the vehicle respectively, increasing the unfolded area of the solar cells, and it is also convenient to cover the front of the vehicle, the roof 100 and the rear of the vehicle with the two rolls of flexible solar cells 203 when parking, providing a sunshade effect for the vehicle.

[0059] Even further, referring to Figure 1 , a plurality of hooks 204 are provided at the outer ends of the flexible solar cells 203. On the one hand, the hooks 204 can be used to cooperate with the roof 100 or the components of the vehicle body when the flexible solar cells 203 are in the unfolded state, so that the flexible solar cells 203 can be stably unfolded and laid on the vehicle body. For example, when the two flexible solar cells 203 are fully unfolded, the hooks 204 of the flexible solar cell 203 unfolded to the front of the vehicle can be hooked on the engine hood or the intake grille, and the hooks 204 of the flexible solar cell 203 unfolded to the rear of the vehicle can be hooked on the trunk, thus ensuring the unfolding stability of the flexible solar cells 203; on the other hand, the hooks 204 can also be used to cooperate with the crossbar 2012 when the flexible solar cells 203 are in the wound state. By hooking the hooks 204 on the crossbar 2012, the winding effect of the flexible solar cells 203 can be ensured, and the flexible solar cells 203 can be prevented from loosening.

[0060] In some embodiments, a plurality of card slots (not shown in the figure) for cooperating with the hooks 204 are provided at both the front end and the rear end of the roof 100. With this setting, in use, the two rolls of flexible solar cells 203 can be respectively pulled out to the front and rear ends of the roof 100, and the hooks 204 can be inserted into the card slots, so that the semi-unfolded flexible solar cells 203 can be fixed on the roof 100. In this state, the flexible solar cells 203 are only located on the roof 100, without blocking the view of the front and rear glass of the car, and will not affect the normal driving of the vehicle.

[0061] Furthermore, a number of magnetic components (not shown in the figure) are arranged at intervals along the extension direction of the flexible solar cell 203. The magnetic components can be small magnets. With such an arrangement, when the flexible solar cell 203 is unfolded on the vehicle roof 100, each magnetic component can be magnetically attracted to the vehicle roof 100, so that the flexible solar cell 203 is closely attached to the vehicle roof 100, reducing the wind resistance during vehicle driving.

[0062] Based on the in-vehicle solar charging system provided in the above embodiments, it mainly has the following three usage states:

[0063] 1) Not charging

[0064] When the vehicle is in scenarios such as rainy weather or indoor parking, the solar cell cannot work. At this time, referring to Figure 2 , the flexible solar cell 203 is wound on the reel 202 and stored in the storage groove 101, and the movable slot door 102 is in the closed state. The appearance of the vehicle is the same as that of an ordinary car.

[0065] 2) Charging while driving

[0066] When driving outdoors, charging can be carried out through the in-vehicle solar charging system. Specifically, the following operations are performed in the parked state: Operate the vehicle central control, first control to open the movable slot door 102, and then control to activate the driver 2011 of the lifting support structure 201. The driver 2011 raises the wound flexible solar cell 203 above the storage groove 101, and then manually pulls the two flexible solar cells 203 to the front end and the rear end of the vehicle roof 100, and inserts the hook 204 into the card slot to fix the unfolded flexible solar cell 203 on the vehicle roof 100, forming a semi-unfolded state as shown in Figure 4 . In this state, the flexible solar cell 203 is only located on the vehicle roof 100, without blocking the view of the front and rear glass of the car, and will not affect the normal driving of the vehicle.

[0067] After charging is completed, take the hook 204 out of the card slot. The flexible solar cell 203 is automatically wound on the reel 202 under the action of the scroll spring. Then operate the vehicle central control, first control the driver 2011 to lower the wound flexible solar cell 203 into the storage groove 101, and then control the movable slot door 102 to close, returning to the non-charging state.

[0068] 3) Charging while parked

[0069] When parked outdoors, charging can be carried out through the in-vehicle solar charging system. Its operation is basically the same as that of charging while driving. The difference is that the two flexible solar cells 203 are respectively pulled out to the front and rear of the vehicle head for fixation, so that the two flexible solar cells 203 are combined to cover the entire vehicle body, forming a state as shown in Figure 5In the fully extended state shown, not only can the deployment area of the flexible solar cell 203 be increased to improve the charging efficiency, but also a sunshade effect can be provided for the vehicle.

[0070] On the other hand, an embodiment of the present invention also provides a vehicle, which includes the above-mentioned in-vehicle solar charging system.

[0071] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0072] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
