DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-Figure 14 As shown, the vehicle-mounted photovoltaic assembly of the present invention comprises: A fixing frame 1, the fixing frame 1 comprises two guide rails 11 arranged opposite to each other, the two guide rails 11 each comprise an unfolding section 111, the extending track of the unfolding section 111 is corrugated and is used for being fixed on the top of the car; A flexible photovoltaic component 2, wherein the flexible photovoltaic component 2 is arranged between the two guide rails 11 and the width direction thereof is consistent with the distribution direction of the two guide rails 11, the flexible photovoltaic component 2 comprises a flexible component layer 21, a flexible shaping layer 22 stacked on the flexible component layer 21, rollers 24 arranged side by side and extending through the flexible shaping layer 22 along the distribution direction of the two guide rails 11, and movable parts 25 arranged at both ends of the rollers 24 and corresponding to the two guide rails 11 one by one, wherein the movable parts 25 are in sliding or rolling cooperation with the corresponding guide rails 11; The driving component 3 is used to drive the flexible photovoltaic component 2 to move between the unfolding station and the storage station. The flexible photovoltaic component 2 at the unfolding station is located between the unfolding sections 111 of the two guide rails 11, and the flexible photovoltaic component 2 at the storage station is separated from the unfolding section 111 and is wound.

[0020] In the present invention, the two guide rails 11 in the fixing frame 1, whose unfolding sections 111 are usually arranged on both sides of the roof of the vehicle, and in the flexible photovoltaic component 2, the shape of the flexible shaping layer 22 is determined by the distribution of the rollers 24 penetrating the flexible shaping layer 22, and then the shape of the flexible component layer 21 is determined. Specifically, since the movable parts 25 at both ends of the rollers 24 slide or roll with the guide rails 11, the shapes of the flexible shaping layer 22 and the flexible component layer 21 distributed between the two guide rails 11 change with the shapes of the corresponding guide rail 11 positions. Therefore, the flexible photovoltaic component 2 is driven by the driving component 3 during the movement between the storage station and the unfolding station.

[0021] According to the above situation, when the flexible photovoltaic component 2 needs to be used for photovoltaic power generation, the flexible photovoltaic component 2 is driven to move by the driving component 3. When the flexible photovoltaic component 2 moves to the unfolding station, the movable parts 25 at both ends of each roller 24 are located on the unfolding section 111 of the guide rail 11. The shapes of the flexible shaping layer 22 and the flexible component layer 21 are consistent with the shape of the unfolding section 111 of the guide rail 11, which are wavy, and the flexible component layer 21 is stacked on the flexible shaping layer 22 to receive sunlight for photovoltaic power generation. Compared with the shape of a flat surface, the wavy flexible component layer 21 is more conducive to increasing the receiving area of ​​sunlight, thereby increasing the photovoltaic power generation; and when the driving component 3 drives the flexible photovoltaic component 2 to move to the storage station, the flexible photovoltaic component 2 is separated from the unfolding section 111 of the guide rail 11 and is wound. On the one hand, the wound flexible photovoltaic component 2 reduces the occupied space, and on the other hand, the space between the unfolding sections 111 of the two guide rails 11 is idle, thereby reserving space for the sunroof on the top of the vehicle, facilitating the use of the sunroof, thereby ensuring the lighting of the vehicle.

[0022] In order to facilitate the fixing of the position of the guide rail 11, in the present invention, a plurality of supporting legs 1111 are provided below the unfolded section 111 of the guide rail 11 and along the extension track of the unfolded section 111, and the bottom ends of the supporting legs 1111 are fixed to the top of the vehicle.

[0023] A further improvement is that the two guide rails 11 also include a storage section 112 fixedly connected to one end of the unfolding section 111 , the extension trajectory of the storage section 112 is a spiral line, and the width direction of the flexible photovoltaic component 2 is perpendicular to the extension trajectory of the guide rail 11 .

[0024] The storage section 112 of the guide rail 11 is usually fixed to the top of the rear of the vehicle. When the driving component 3 drives the flexible photovoltaic component 2 to move to the storage position, the movable part 25 is located in the storage section 112 in a spiral line shape, so that the flexible component layer 21 and the flexible shaping layer 22 are wound.

[0025] A further improvement is that the driving component 3 includes a driving unit 31, a winding drum 32 and a memory steel wire 33. The axial direction of the winding drum 32 is consistent with the width direction of the flexible photovoltaic component 2. The driving unit 31 drives the winding drum 32 to rotate around its own axis. The two ends of the memory steel wire 33 are respectively connected to the side wall of the winding drum 32 and one end of the flexible photovoltaic component 2.

[0026] In the driving assembly 3, the winding drum 32 is arranged between the storage sections 112 of the two guide rails 11. The driving unit 31 provides power for the winding drum 32 to rotate around its own axis, and the winding drum 32 and the flexible photovoltaic assembly 2 are connected by a memory wire 33. The memory wire 33, that is, the nickel-titanium alloy memory wire, is an alloy material with a special shape memory effect and superelasticity. It has a certain elastic deformation function, which is convenient for winding and unwinding deformation with the rotation of the winding drum 32. When winding, it can pull the flexible photovoltaic assembly 2 away from the unfolding station, and when unwinding, it can push the flexible photovoltaic assembly 2 away from the storage station.

[0027] The specific structure of the driving component 3 is as follows: Figure 3-Figure 7 As shown, in order to facilitate the installation of the drive component 3, the fixing frame 1 also includes two side panels 13, and the two side panels 13 are fixedly connected to the storage sections 112 of the two guide rails 11 in a one-to-one correspondence. The two storage sections 112 are located between the two side panels 13, and end covers 34 are fixedly provided at both ends of the winding drum 32. A bearing 35 is provided between the end cover 34 and the corresponding side panel 13, and the bearing 35 is located on the inner side of the vortex-shaped storage section 112. The outer ring of the bearing 35 is fixedly connected to the side panel 13, and the inner ring is fixedly connected to the end cover 34; the two side panels 13 are fixedly connected by a bending plate 12, and the bending plate 12 is formed by bending a rectangular plate, and the width direction of the bending plate 12 is consistent with the width direction of the flexible photovoltaic component 2.

[0028] The driving assembly 3 is arranged on one of the side panels 13. Specifically, the driving assembly 3 includes a driving motor 311, a driving wheel 312, a synchronous belt 313 and a driven wheel 314, wherein the housing of the driving motor 311 is fixed directly below the bending plate 12, the output shaft of the driving motor 311 is fixedly connected to the driving wheel 312 coaxially, the driving wheel 312 is transmission-connected to the driven wheel 314 through the synchronous belt 313, and the driven wheel 314 is fixedly connected to the end cover 34 coaxially.

[0029] After the driving motor 311 is started, it drives the driving wheel 312 to rotate, and the driving wheel 312 drives the driven wheel 314 to rotate through the synchronous belt 313, so that the end cover 34 and the winding drum 32 connected to the driven wheel 314 coaxially rotate around their own axis. The driving motor 311 is located below the bending plate 12, which can reduce the width of the device and avoid the device occupying too much space in the width direction after being installed on the vehicle, causing excessive wind resistance when the vehicle is driving.

[0030] In order to protect the driving motor 311 , the driving wheel 312 , the synchronous belt 313 and the driven wheel 314 , the driving assembly 3 also includes a protective cover 315 , which is fixedly connected to the side plate 13 and is arranged outside the driving motor 311 , the driving wheel 312 , the synchronous belt 313 and the driven wheel 314 .

[0031] A further improvement is that the guide rail 11 is a guide groove, and the movable member 25 is a roller rolling in the guide groove.

[0032] The movable part 25 is a roller that rolls in the guide groove. Compared with the design of sliding fit, the rolling fit can reduce the friction force on the movable part 25 when it moves on the guide rail 11, making it convenient for the flexible photovoltaic component 2 to move between the two guide rails 11 and adjust the shape of the flexible photovoltaic component 2 so that the flexible photovoltaic component 2 can be flexibly switched between the storage station and the deployment station.

[0033] A further improvement is that in the fixing frame 1, the bending plate 12 and the side plate 13 are combined to form a protective shell, and a strip opening 111 facing the unfolded sections 111 of the two guide rails 11 is provided on the circumferential side wall of the protective shell for the flexible photovoltaic assembly 2 to pass through, and the storage sections 112 of the two guide rails 11 are both arranged in the inner cavity of the protective shell.

[0034] The specific structure of the fixing frame 1 is as follows: Figure 3 and Figure 4 As shown, in the fixing frame 1, the bending plate 12 and the side plates 13 on both sides of the bending plate 12 are fixedly connected to form a protective shell to protect the winding drum 32 inside and the storage section 112 of the guide rail 11. The protective shell is provided with a strip opening, which extends along the width direction of the flexible photovoltaic component 2 for the flexible photovoltaic component 2 to pass through. When the flexible photovoltaic component 2 moves to the storage station, the flexible component layer 21 and the flexible shaping layer 22 are both accommodated in the protective shell, thereby reducing the contact between the flexible component layer 21 and the outside, reducing dust accumulation, and ensuring the cleanliness of the surface of the flexible component layer 21, so as to increase the photovoltaic power generation and extend the cleaning cycle.

[0035] A further improvement is that the flexible photovoltaic component 2 further includes a sealing strip 26, and the sealing strip 26 is used to cover the strip-shaped opening when the flexible photovoltaic component 2 is located at the storage position.

[0036] Specifically, the flexible photovoltaic component 2 also includes a sealing strip 26 and a packaging strip 28 arranged side by side. The sealing strip 26 and the packaging strip 28 are respectively fixed at both ends of the flexible component layer 21, and the length direction of the two is consistent with the width direction of the flexible component layer 21. The packaging strip 28 is fixedly connected to the end of the memory steel wire 33 away from the winding drum 32. When the flexible photovoltaic component 2 is located at the storage station, the sealing strip 26 can cover the strip-shaped opening and enclose the protective shell to form a protective cavity, which is isolated from the outside world, thereby further reducing the dust accumulation on the surface of the flexible component layer 21, thereby increasing the photovoltaic power generation and extending the cleaning cycle.

[0037] A further improvement is that the ends of the unfolding section 111 facing away from the storage section 112 are connected via a positioning strip 14 , and the sealing strip 26 is magnetically engaged with the positioning strip 14 .

[0038] Specifically, a magnet 141 is provided on the positioning strip 14, and the sealing strip 26 is a magnetic conductor, and its material is preferably iron. Through the above design, when the driving component 3 controls the flexible photovoltaic component 2 to move to the unfolding position, the magnet 141 on the positioning strip 14 is used to attract the sealing strip 26 made of iron, thereby fixing the end position of the flexible photovoltaic component 2 and preventing the position of the flexible photovoltaic component 2 from changing.

[0039] A further improvement is that the flexible shaping layer 22 is a sponge layer, a water pipe 27 is arranged in the sponge layer, and the side wall of the water pipe 27 is provided with water-permeable holes 271 distributed along its own axial direction. A water supply component 4 is also provided on the fixed frame 1, and the water supply component 4 is used to supply water to one end of the water pipe 27.

[0040] The sponge layer can be rolled and deformed, and has a porous structure. A water pipe 27 is arranged inside, so that after the water supply component 4 supplies water to the water pipe 27, the water flows out through the water permeable holes 271 and spreads along the micropores inside the sponge layer to the entire flexible shaping layer 22, so that the water flow can fully contact the flexible component layer 21. When the flexible component layer 21 generates heat through photovoltaic power generation, the water flow spreading through the sponge layer fully absorbs the heat of the flexible component layer 21, and after absorbing heat, it can absorb heat again through evaporation, thereby ensuring that the flexible component layer 21 performs photovoltaic power generation in a low temperature environment, thereby ensuring the efficiency of photovoltaic power generation.

[0041] Three water pipes 27 are provided, which are evenly spaced along the width of the flexible shaping layer 22. The water pipes 27 are densely covered with water permeable holes 271. An extension section 272 is provided at one end of the water pipe 27 adjacent to the packaging strip 28. The extension section 272 penetrates the packaging strip 28 and is connected to the water supply component 4, so that after the water supply component 4 delivers water to the water pipe 27 through the extension section 272, the cooling water can be quickly and evenly filled in the entire flexible shaping layer 22, so as to achieve rapid and uniform heat absorption and cooling of the flexible component layer 21.

[0042] A further improvement is that a flexible waterproof layer 23 is laminated and connected to the side of the sponge layer facing away from the flexible component layer 21 .

[0043] The flexible waterproof layer 23 is a flexible waterproof film, which is laminated and fixed on the side of the sponge layer facing away from the flexible component layer 21. After adopting this design, the flexible waterproof layer 23 can prevent water from dripping from the bottom of the sponge layer after the flexible photovoltaic component 2 moves to the deployment position and supplies water to the water pipe 27 through the water supply component 4. In this way, the water storage capacity of the sponge layer is enhanced, which facilitates the water flow inside the sponge layer to be retained to absorb the heat generated by the flexible component layer 21 after photovoltaic power generation. After absorbing the heat, it is discharged from both sides of the flexible shaping layer 22 by volatilization.

[0044] A further improvement is that the extension trajectory of the water pipe 27 is consistent with the extension trajectory of the flexible photovoltaic component 2. The water supply component 4 includes a water pump 41, a water supply shell 42 and a water supply pipe 43. The water pump 41 is arranged on the fixed frame 1, and the input end is used to connect to an external water source. The output end is coaxial with the winding drum 32 and is sealed with the water supply shell 42. The water supply shell 42 is arranged in the winding drum 32 and is fixedly connected to the water supply pipe 43. The water supply pipe 43 is fixedly passed through the winding drum 32 and is connected to the water pipe 27.

[0045] Specifically, Figure 8-Figure 10 , Fig.13 As shown, among the two side plates 13, on one of the side plates 13 away from the driving assembly 3, a fastening plate 131 is fixed on the side opposite to the winding drum 32, and a positioning cylinder 132 penetrating one end of the winding drum 32 is fixed coaxially on the side adjacent to the winding drum 32. The fastening plate 131 and the side plate 13 are enclosed to form a fastening channel, and the water pump 41 is fixedly accommodated in the positioning cylinder 132, and the input end is penetrated through the inner side of the fastening channel, and the output end is coaxial with the winding drum 32. The water supply shell 42 is coaxially arranged in the winding drum 32, and the end thereof facing away from the water pump 41 is closed, and the circumferential inner wall of the end adjacent to the water pump 41 is sealed with the circumferential outer edge of the output end of the water pump 41. A water supply pipe 43 corresponding to the water delivery pipe 27 is fixedly connected to the water supply shell 42. The water supply pipe 43 extends radially along the winding drum 32 and is fixedly passed through the side wall of the winding drum 32. The water supply pipe 43 and the extension section 272 are connected to each other through a connecting pipe 44, which is a rubber tube.

[0046] After adopting the above design, the position of the input end of the water pump 41 is limited by the fastening plate 131. The input end of the water pump 41 is used to connect to an external water source. After the water pump 41 is started, it draws water from the external source and transports it to the water supply shell 42. The cooling water enters the water delivery pipe 27 along the water supply pipe 43 and the connecting pipe 44, and is discharged through the water permeable hole 271, spreading on the flexible shaping layer 22 made of sponge, so that the cooling water can fully contact with the flexible component layer 21, and absorb heat and cool the corrugated flexible component layer 21 at the unfolding station to ensure its photovoltaic power generation efficiency.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
