[0029] like Figure 1 and Figure 3 As shown, the foldable photovoltaic panel range extender for electric vehicles includes a controller 4 connected to the battery and / or motor of the electric vehicle, and the range extender also has: at least two foldable photovoltaic panel units 1; and a flexible support base 2 for supporting at least two of the foldable photovoltaic panel units 1; and a snap-fit ​​hook structure 3 arranged on the flexible support base 2 at the bottom of at least one foldable photovoltaic panel unit 1; wherein: the snap-fit ​​hook structure 3 is used to fit or connect the folded foldable photovoltaic panel units 1 closely together for storage, so as to fix them on the electric vehicle or store them after removal; connecting components 8 are also provided at both ends of several of the foldable photovoltaic panel units 1. When the foldable photovoltaic panel range extender for electric vehicles is in use, it is only necessary to fold the several foldable photovoltaic panel units 1 along the foldable part of the flexible support base 2 to store or open them for use, and the foldable photovoltaic panel range extender for electric vehicles can be fixed in the corresponding position by providing connecting components 8 at both ends of several of the foldable photovoltaic panel units 1, so that installation and maintenance are very convenient. Figure 1 and Figure 3 It can be seen that the controller 4 connected to the electric vehicle battery and / or motor is generally placed at the bottom of the foldable photovoltaic panel unit 1. The purpose of this arrangement is to facilitate transportation and to protect and shield the controller 4 from rain after installation.

[0030] In at least one embodiment, an end snap-fit ​​hook structure 7 is provided at one end of the foldable photovoltaic panel unit 1, and a rotatable cover 5 is provided on the side. After the rotatable cover 5 is rotated, it is connected to the foldable photovoltaic panel unit 1 through the snap-fit ​​hook structure 3 to achieve snap-fit ​​storage. That is to say, the rotatable cover 5 is used to protect the foldable photovoltaic panel unit 1 after several foldable photovoltaic panel units 1 are rotated and snapped together, so as to prevent the surface of the foldable photovoltaic panel unit 1 from being damaged during transportation.

[0031] In at least one embodiment, Figure 1 and Figure 2 、 Figure 5 As shown, a buffer pad 6 is provided between the end buckling hook structure 7 and the foldable photovoltaic panel unit 1 to cushion the impact received by the foldable photovoltaic panel unit 1 during transportation.

[0032] In at least one embodiment, Figure 3 and Figure 4 As shown, the connecting component 8 is used to hook the entire foldable photovoltaic panel range extender on the corresponding part of the electric vehicle body. During the actual operation, the connecting component 8 can be any one or a combination of elastic bands, cloth belts, strapping belts, iron wires, etc., so as to achieve its bundling and tightening functions.

[0033] In at least one embodiment, the snap-fit ​​hook structure 3 and the end snap-fit ​​hook structure 7 are any one of nylon strap, spring snap-fit ​​structure, and cable clamp snap-fit ​​structure, or, in the specific implementation process, as long as the corresponding nylon strap, spring snap-fit ​​structure, and cable clamp snap-fit ​​structure are respectively provided on the snappable parts, snap-fitting can be achieved.

[0034] In at least one embodiment, see Figure 1 、 Figure 3 and Figure 5 The flexible support base plate 2 is made of a material that can be bent back into place, such as plastic sheeting, rainproof cloth, PU board, PVC board, kraft paper, canvas, etc. In a specific implementation process, an installation gap 9 of the flexible support base plate 2 having a certain length can be directly arranged between two adjacent foldable photovoltaic panel units 1 so that the two foldable photovoltaic panel units 1 can be freely overlapped. Alternatively, two foldable photovoltaic panel units 1 can be installed with sufficient gap 9 for easy installation.

[0035] In at least one embodiment, Figure 6 As shown, a plurality of Velcro components 10 that can be stuck and opened to each other are installed on the installation spacer 9 between the two adjacent foldable photovoltaic panel units 1 on the flexible support base plate 2. The Velcro components 10 are provided for the purpose of leaving sufficient margin when the foldable photovoltaic panel unit 1 is installed on the electric vehicle in the case of poor local space conditions, so that the electric vehicle foldable photovoltaic panel range extender has better installability.

[0036] In at least one embodiment, the number of the foldable photovoltaic panel units 1 ranges from 2 to 5, and the specific number setting is related to the location where it is installed on the electric vehicle. For example, if the entire electric vehicle foldable photovoltaic panel range extender needs to be installed on the front windshield and left and right sides of the electric vehicle, 2 or 3 foldable photovoltaic panel units 1 are more appropriate; if it is installed on the side and / or rear of the electric vehicle body, only one foldable photovoltaic panel unit 1 is needed. If it is installed on the top of the electric vehicle, 1, 2, 3, 4, or 5 foldable photovoltaic panel units 1 can be set, which can all meet its charging requirements and can maximize the layout of the area of ​​the foldable photovoltaic panel unit 1 to ensure sufficient charging.

[0037] In at least one embodiment, Figure 3 As shown, at least one connecting assembly is also configured at the bottom of the flexible support base 2. Each connecting assembly includes a slide rail 11 and a connecting hook 12 that slides and rotates within the slide rail 11 and is used to connect to the body of the electric vehicle. In a specific configuration, the connecting hook 12 can be configured to connect to the slide rail 11 with a ball head that snaps into the slide groove of the slide rail 11, adjusting the specific location and angle of connection with the electric vehicle body. This not only meets the requirement of conveniently connecting the foldable photovoltaic panel range extender to the electric vehicle body, but also allows the configuration of the connecting assembly to flexibly adjust the angle of the foldable photovoltaic panel unit 1 relative to the electric vehicle body, that is, to adjust the facing angle of the foldable photovoltaic panel range extender when suspended, thereby improving its power generation efficiency and maximizing the range of the electric vehicle. In addition, the specific location of the connecting assembly can be on the flexible support base 2 on the back of any foldable photovoltaic panel unit 1, and the specific number can be one or more. In a specific implementation, the connection method between the slide rail 11 and the flexible support base 2 can be adhesive, sewing, or other connection methods.
