[0036] The present application is described below based on embodiments, but the present application is not limited to only these embodiments. In the following detailed description of the present application, some specific details are described in detail. The present application can also be fully understood without the description of these details by those skilled in the art. In order to avoid confusion of the essence of the present application, well-known methods, processes, procedures, elements and circuits are not described in detail.

[0037] In addition, those skilled in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0038] Unless otherwise clearly defined and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixedly connected, can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] For ease of description, spatially relative terms, such as "inner," "outer," "beneath," "below," "lower," "above," "upper," and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures.

[0040] Unless the context clearly requires otherwise, throughout the description, the words "comprise," "comprising," and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to."

[0041] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various elements, but not to indicate or imply relative importance. In addition, in the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0042] The existing solar cell panel is usually composed of a plurality of solar cell pieces, and the solar cell pieces are connected in series. When there are shaded solar cell pieces in the solar cell panel, the shaded solar cell pieces cannot smoothly transmit current and / or voltage to the unshaded solar cell pieces, so that the maximum rated power of the shaded solar cell pieces is reduced due to shading, and the overall output power of the solar cell panel also appears a large loss. Moreover, the more the number of shaded solar cell pieces is, the more the shading area of the solar cell pieces is, and the more the output power loss is. In view of this, the embodiment aims to provide a solar cell panel, a basket and a vehicle to reduce the output power loss of the solar cell panel under shading.

[0043] Figure 1 is a schematic view of the basket of the utility model embodiment. As Figure 1As shown, the basket 1 in the embodiment includes a bottom plate 11 and a solar cell panel 2 arranged on the bottom plate 11. When sunlight shines on the solar cell panel 2, the solar cell panel 2 absorbs sunlight based on internal components, and converts solar radiation energy into electrical energy directly or indirectly through photoelectric effect or photochemical effect, which can be stored by a storage battery and output externally when needed to provide electrical energy for components that need power supply. For example, by connecting the solar cell panel with the positioning system and communication module on the shared vehicle, the solar cell panel can power the positioning system and communication module on the vehicle, facilitate quick positioning and communication of the vehicle, ensure that the vehicle can be unlocked anytime and anywhere, and facilitate optimization of vehicle layout and user search and use of the vehicle.

[0044] However, due to the change of the sun's position, the basket (including the frame on the basket, the objects pasted on the basket, etc.) will cast a shadow on the solar cell panel and project the shadow on the solar cell panel, forming a shielding area, and the part of the solar cell panel located in the shielding area cannot output normal output power due to insufficient light intensity, resulting in a decrease in the overall output power of the solar cell panel and a certain power loss compared with the output power in the case without shielding. Based on this, the solar cell panel 2 provided in the embodiment includes a plurality of solar cell panel groups arranged in different areas, and the solar cell panel groups are connected in parallel to reduce the output power loss of the solar cell panel in the case of shading.

[0045] Figure 2 is a structural schematic view of the solar cell panel of the embodiment of the utility model. In combination with Figure 1 and Figure 2 As shown, the solar cell panel 2 in the embodiment is installed in the basket 1 and can be arranged on the bottom plate 11 in the basket 1. Meanwhile, the solar cell panel 2 in the embodiment includes a plurality of solar cell panel groups, each of which is arranged in a different area and connected in parallel with the other solar cell panel groups. Thus, in use, each solar cell panel group does not affect the other solar cell panel groups, and each solar cell panel group in the solar cell panel absorbs solar energy for charging and outputting electrical energy. When some solar cell panel groups in the solar cell panel are shaded, the other unshaded solar cell panel groups can still output normal output power without being affected by the shaded solar cell panel groups, which can reduce the output power loss of the solar cell panel in the shading scenario and improve the overall output power and charging efficiency of the solar cell panel.

[0046] Optionally, the shape and size of the solar panel in the embodiment can be set according to the shape and size of the basket, so that the solar panel is adapted to the basket, the setting of the solar panel is facilitated, and the aesthetic appearance of the cooperation of the solar panel and the basket is improved.

[0047] Optionally, the easily-shielded area and the not-easily-shielded area of the basket bottom plate can be determined according to the actual environmental information and the shape of the basket, and the setting area of each solar cell group in the solar panel is set based on the easily-shielded area and the not-easily-shielded area of the basket bottom plate.

[0048] Further, since the setting position and shape and size of the solar panel in the basket are generally fixed, but the positions corresponding to the shielded area and the not-shielded area generated on the solar panel are dynamically changed, the easily-shielded area and the not-easily-shielded area on the solar panel can be determined based on the solar radiation law of the geographical area where the solar panel is located in the embodiment, the probability of the easily-shielded area being shielded is higher than that of the not-easily-shielded area being shielded, and the probability of being shielded can be determined by the shielding parameters such as the size of the shielded area and / or the shielded time. For example, the time length of the A area existing the shielded area in a day is 5 hours, and the time length of the B area existing the shielded area in a day is 2 hours, so the A area is the not-easily-shielded area, and the B area is the easily-shielded area.

[0049] Further, taking the basket shown in Figure 1 as an example, the basket 1 further includes a surrounding part 12 and a mounting part 13 connected with the vehicle body in addition to the above-mentioned bottom plate 11, and the light-shielded area generated by the solar panel under the natural shielding condition of the basket has a close relationship with the surrounding part 12, and the easily-shielded area 21 formed generally includes the area 1, the area 4 and the area 3 shown in Figure 2 , the not-easily-shielded area 22 includes the area 2 shown in Figure 2 , and the easily-shielded area as a whole is in the shape of “Dang”, and the opening of the “Dang” shape area faces the mounting part 13 (when the mounting part 13 is connected with the handle, the opening of the “Dang” shape area faces the handle). Therefore, when the solar cell groups are set, the solar cell groups can be respectively set at the positions corresponding to the area 1, the area 2, the area 3 and the area 4 in the embodiment, and the solar cell groups on each area are connected in parallel. Thus, by setting different solar cell groups in different areas by the above-mentioned method, the charging and discharging processes of different solar cell groups do not affect each other, and the output power loss of the solar panel is reduced.

[0050] It should be noted that the shape, size and number of the solar cell group setting area in the embodiment can be set and adjusted according to the shape, size of the easy-to-block area and the non-easy-to-block area under the use scenario of the solar cell panel and / or the shape, size and / or number of the solar cell used in the solar cell group. The examples given herein are only for illustration.

[0051] Further, in the embodiment, the existing flexible solar cell has flexibility and ductility, can adapt to various shapes and sizes of installation area, and can also output electric energy well under weak light irradiation. The rigid solar cell has a relatively fixed structure, lacks flexibility and ductility, but has better performance in outputting electric energy under strong light irradiation.

[0052] Therefore, after determining the setting area of each solar cell group, the same type of solar cell group can be set in each area in the embodiment, that is, all the solar cells in the solar cell group corresponding to each area are set as flexible solar cells or rigid solar cells. Alternatively, the corresponding type of solar cell group can be set according to the light blocking property (i.e. easy-to-block or non-easy-to-block) of each area, that is, the flexible solar cell and the rigid solar cell coexist. Thus, the plurality of solar cell groups in the solar cell panel in the embodiment includes at least one flexible solar cell group, and the at least one flexible solar cell group is arranged in the corresponding easy-to-block area. In addition, the plurality of solar cell groups in the solar cell panel includes at least one rigid solar cell group, and the at least one rigid solar cell group is arranged in the corresponding non-easy-to-block area.

[0053] In an alternative implementation, as shown in the area 1, area 2, area 3 and area 4 in Figure 2 In the embodiment, by setting the flexible solar cell in the easy-to-block area and the non-easy-to-block area on the basket, the solar cell panel can continuously output electric energy under the shading condition, and the stability of the output power is higher. In addition, since the flexible solar cell has flexibility and ductility, the use of the flexible solar cell can reduce the installation gap between the solar cell panel and the basket, increase the installation adaptability of the solar cell panel and the basket, expand the light absorption area of the solar cell panel, and be beneficial to improving the overall output power of the solar cell panel.

[0054] In another alternative implementation, as shown in the solar cell group setting area in Figure 2 In the embodiment, the area 1, area 3 and area 4 are easy-to-block areas, and the area 2 is a non-easy-to-block area. Based on this, as shown in the area 1, area 2, area 3 and area 4 in Figure 2The flexible battery piece groups are arranged on the area 1, the area 3 and the area 4 shown in the figure, and the rigid battery piece group is arranged on the area 2. Correspondingly, the solar cell panel in the embodiment comprises at least one flexible battery piece group and at least one rigid battery piece group, each flexible battery piece group is arranged in the area prone to be blocked, and each rigid battery piece group is arranged in the area not prone to be blocked. At this time, the mounting area formed by each flexible battery piece group is in the shape of'', and the opening of the'' shaped area faces the handle. Each flexible battery piece group is located at the periphery of the rigid battery piece group. Therefore, by the arrangement mode, the solar cell pieces of the appropriate type are selected for each area based on the light blocking attribute of the arrangement position of each solar cell piece group, so that the flexible battery piece group in the area prone to be blocked can supplement energy under weak light intensity (i.e. light intensity), and the rigid battery piece group in the area not prone to be blocked can convert more solar energy under strong light intensity into electric energy, that is, the solar cell pieces in each area can fully exert the performance, which is beneficial to further reduce the output power loss of the solar cell panel and improve the output power of the solar cell panel.

[0055] In another optional implementation, in the embodiment, rigid battery pieces can also be arranged on the area 1, the area 2, the area 3 and the area 4 shown in the figure. Figure 2 Therefore, in the embodiment, by arranging all the battery pieces on the solar cell panel as rigid battery pieces, each area can fully utilize solar energy and convert solar energy into electric energy under the condition of no light blocking, the utilization efficiency of solar energy of the solar cell panel is improved, and then the overall output power of the solar cell panel is improved.

[0056] It should be noted that the number of the solar cell piece groups on each arrangement area in the embodiment, and the shape, size and number of the solar cell pieces in the solar cell piece groups can be set and adjusted according to the actual use scene. For example, the number of the solar cell piece groups on each area and the number of the solar cell pieces in each solar cell piece group can be one or more, the shape of each solar cell piece can be the same as or different from the shape of the corresponding arrangement area, the size of each solar cell piece can be the same as or smaller than the area of the corresponding arrangement area, and the like. The embodiment is not limited in this regard.

[0057] Further, in order to understand the working process of the solar cell panel in the embodiment, the equivalent circuit of the solar cell panel is introduced.

[0058] Figure 3 is the circuit principle diagram of the solar cell panel in the embodiment of the utility model. As shown in the figure, Figure 3As shown, the solar panel 2 in the embodiment includes a plurality of solar cell groups 23 and a boost module 24. Among them, the solar cell group 23 includes at least one power supply circuit, and the power supply circuits are connected in parallel. The boost module 24 is connected between the output end of each solar cell group and the to-be-charged device 3, which can be a positioning system, a communication module, a lock body, or other devices on the vehicle that need to be powered. Thus, the charging function of the solar panel is realized by at least one power supply circuit in each solar cell group, and the output power is outputted externally after charging is completed, and then the output voltage of the solar cell group is boosted to a voltage level suitable for charging the to-be-charged device by the boost module, so that the solar panel charges the to-be-charged device 3.

[0059] Optionally, the power supply circuit in the embodiment includes at least one solar cell and at least one freewheeling diode. Among them, each solar cell is connected in series, and each freewheeling diode is connected in parallel with the corresponding solar cell. And the conduction direction of the freewheeling diode in the embodiment is the same as the current direction of the solar cell. When the solar cell is illuminated and generates current, the freewheeling diode is in a forward conduction state, allowing current to flow out of the solar cell; when the solar cell is not illuminated or generates little current, the freewheeling diode is in a reverse blocking state, which can prevent current from flowing into the solar cell. Thus, through the above setting mode, while ensuring the output of the solar cell, the current can be prevented from flowing from the outside to the solar cell, avoiding reverse charging of the solar cell under no-light conditions such as night, cloudy day, or shading, thereby damaging the solar cell and the solar panel. And when other series-connected solar cells in the same power supply circuit are shaded, the freewheeling diode can make the current flow, which can further reduce the shading effect.

[0060] Optionally, as shown, Figure 3 The solar panel 2 in the embodiment also includes at least one voltage sampling circuit 25. Each voltage sampling circuit 25 is connected with the corresponding solar cell group, which is used to sample the output voltage of the corresponding solar cell group, so as to adjust the type of the solar cell group in each region or divide the region into smaller granularity, thereby optimizing the overall performance of the solar panel, and further improving the overall output power of the solar panel.

[0061] Further, the voltage sampling circuit in the embodiment includes two series resistors, the resistance of which is set according to experience and actual application scenarios, and the voltage at the node where the two resistors are connected is the output voltage of the solar cell group in the sampled region. Thus, by sampling the output voltages of different regions, verifying the rationality of the arrangement of the flexible solar cell group and the rigid solar cell group in the solar cell panel based on the values of the output voltages in the shadowing and non-shadowing conditions and the output power calculated from the output voltages, the output power of the solar cell panel can be further improved.

[0062] Optionally, as shown in Figure 3 , the solar cell panel 2 in the embodiment further includes at least one protection circuit 26. Each protection circuit 26 is arranged at the output end of the corresponding solar cell group, for blocking external current from entering the interior of the solar cell group, thereby improving the overall safety of the solar cell panel. Further, the protection circuit in the embodiment adopts a protection diode, the anode of each protection diode is connected with the output end in the corresponding solar cell group, and the cathode of each protection diode is connected with the boost module. Thus, by arranging the protection diode in the above manner, the output current of other solar cell groups can be prevented from entering the corresponding solar cell group in reverse, thereby protecting the solar cell group and the solar cell therein from damage and improving the safety of the solar cell panel in use.

[0063] For ease of understanding, the equivalent circuit of the solar cell panel as shown in Figure 4 is given in the embodiment, and the equivalent cell arrangement diagram of the solar cell panel as shown in Figure 5 is given in the embodiment. It can be known from Figure 4 and 5 that there are four solar cell group arrangement regions on the solar cell panel, including region 1, region 2, region 3 and region 4, and each region is provided with the power supply circuit, the voltage sampling circuit 25 and the protection diode 26 corresponding to the region. Among them, region 1, region 3 and region 4 are easy-to-block regions, and region 2 is a non-easy-to-block region. The solar cell groups in region 1, region 3 and region 4 can adopt the same arrangement manner. Hereinafter, taking region 1 and region 2 as examples, the equivalent circuits in each region are described.

[0064] In region 1, a solar cell group and the voltage sampling circuit and the protection diode corresponding to the solar cell group are arranged. The solar cell group includes a power supply circuit. The anode of the protection diode is connected with the output end of the power supply circuit, and the cathode of the protection diode is connected with the input end of the boost module. The voltage sampling circuit is connected in parallel with the power supply circuit, and the output voltage of the determined region 1 is the voltage at the connection point of the two resistors.

[0065] Further, the power supply circuit in the region 1 includes 3 solar cell pieces in series, and each solar cell piece is a flexible solar cell piece, that is, the solar cell piece group is a flexible solar cell piece group. Meanwhile, each solar cell piece is connected with a freewheeling diode in parallel at both ends, and the conduction direction of the freewheeling diode is consistent with the current direction in the corresponding solar cell piece.

[0066] In the region 2, as shown in Figure 4 the solar cell piece group and the voltage sampling circuit and the protection diode corresponding to the solar cell piece group are arranged. The solar cell piece group includes two power supply circuits 231 connected in parallel. The anode of the protection diode is connected with the output end of the solar cell piece group (that is, the output end of the power supply circuit), and the cathode of the protection diode is connected with the input end of the boost module. The voltage sampling circuit is connected with the solar cell piece group in parallel, and the output voltage of the determined region 2 is the voltage of the two resistance connection points.

[0067] Further, each power supply circuit in the region 2 includes 3 solar cell pieces in series, and each solar cell piece is a rigid solar cell piece, that is, two rigid solar cell piece groups are arranged in the region 2. Meanwhile, each solar cell piece is connected with a freewheeling diode in parallel at both ends, and the conduction direction of the freewheeling diode is consistent with the current direction in the corresponding solar cell piece.

[0068] The technical scheme of the embodiment arranges the solar cell piece groups in the solar panel in different regions in parallel, so that when some solar cell piece groups are blocked, the other unblocked solar cell piece groups can still normally output power, thereby reducing the output power loss of the solar panel in the shading scene, and being beneficial to improving the charging efficiency of the solar panel.

[0069] Further, the embodiment also provides a vehicle, and the vehicle includes the basket as described above, and the arrangement of the basket has been described above, and will not be repeated here.

[0070] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
