Description

Technical field:

[0002] The invention relates to a vehicle photovoltaic deployment device and a working method thereof. Background technology:

[0004] After decades of development, photovoltaic technology has been used more and more widely and has been applied to various installation environments. However, due to the large size, heavy weight and low power of photovoltaic modules, the limited installation area of ​​automobiles and the high power requirements of automotive electrical appliances, photovoltaic modules have not been well applied to automobiles.

[0005] Conventional photovoltaic modules are monolithic in structure, using glass plates, back plates and EVA to encapsulate the cells. The cells are connected in series, and then EVA is laid on both sides of the cells, placed between the cell string and the back plate, and placed in a laminator. The EVA is heated to melt the EVA, and the layers are bonded together. Finally, the photovoltaic modules are cooled and taken out. Conventional photovoltaic modules have the following problems if they are to be used in automobiles:

[0006] 1. Conventional photovoltaic modules are large in size. For example, a 300W photovoltaic module has an area of ​​1.9 square meters (about 1m x 1.9m).

[0007] 2. The available environment of cars is poor. The top of cars usually has a curvature, so there is no completely flush installation environment. In addition, the available installation area on the top is small. For example, the available area on the top of a common SUV is only 0.9x1.2 meters, and at most only one 100W photovoltaic module can be installed. One photovoltaic module is far from enough for common electrical appliances in the car. For example, the power of a laptop is about 120 watts, which cannot meet the regular use of people in the car.

[0008] 3. Inconvenient to carry. Large-area photovoltaic modules are not easy to carry. For example, large-area photovoltaic modules cannot be put into the trunk of a car, nor can they be fixed to the roof rack.

[0009] 4. Conventional photovoltaic modules are difficult to install and disassemble. Usually, they are not disassembled after being installed in a certain environment. However, in the automotive environment, various automotive accessories are usually required to be easy to install and disassemble to cope with various environmental conditions.

[0010] Therefore, how to utilize the limited installation area of ​​the roof to achieve relatively large power supply to meet the requirements of the passengers in the car, and how to easily dismantle it when not in daily use is a technical problem that needs to be solved by those skilled in the art. Summary of the invention:

[0012] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a vehicle-use photovoltaic deployment device and a working method thereof. The vehicle-use photovoltaic deployment device can be used on a vehicle and can provide a larger power supply after being deployed.

[0035] In order to make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description.

[0036] The vehicle photovoltaic deployment device of the present invention includes a mounting beam 1 arranged on the roof and a left mounting frame 2 and a right mounting frame 3 arranged opposite to each other on the mounting beam. The mounting beam 1 can be formed by bending an aluminum pipe with a circular or elliptical cross-section. The two ends of the mounting beam 1 are connected to the roof through a support seat body. The support seat body can be a pipe sleeve body with a flange. The pipe sleeve body covers the end of the mounting beam 1, and the flange is locked on the roof by screws; a first photovoltaic panel 4, a second photovoltaic panel 5 and a third photovoltaic panel 6 are arranged from top to bottom between the left and right mounting frames, the first photovoltaic panel 4 is fixed between the left and right mounting frames, the second photovoltaic panel 5 and the third photovoltaic panel 6 slide relative to the left and right mounting frames along the length direction of the vehicle body, and the second photovoltaic panel 5 and the third photovoltaic panel 6 are synchronously extended and retracted through a pulley synchronization mechanism 13 arranged on the inner side of the left and right mounting frames.

[0037] The left mounting frame 2 and the right mounting frame 3 can be made of aluminum alloy profiles, and their specific structures are as follows:

[0038] The inner sides opposite to each other of the left and right mounting frames are provided with three grooves, namely, an upper groove 8, a middle groove 9 and a lower groove 10 (the cross-sections of the three grooves may be T-shaped or the like), the upper groove is used to limit the upper slide rail 11 connected to the second photovoltaic panel 5, the lower groove 10 is used to limit the lower slide rail 12 connected to the third photovoltaic panel 6, and the middle groove 9 is used to limit the pulley synchronization mechanism 13; the middle parts of the left and right mounting frames are provided with a rectangular through groove 21 (the four corners of the rectangular through groove 21 are rounded, and are obtained by machining on the profile), and a limiting rubber block 22 embedded in the rectangular through groove is sleeved on the mounting crossbeam (the inner hole of the limiting rubber block 22 is consistent with the cross-sectional shape of the mounting crossbeam 1, and the outer peripheral shape of the limiting rubber block 22 is consistent with the shape of the rectangular through groove 21); the lower surfaces of the left and right mounting frames are provided with bottom A groove 23, a bottom nut 24 matching its cross section is arranged in the bottom groove, and a supporting foot 25 screwed with the bottom nut from bottom to top is arranged at the bottom of the left and right mounting frames; the upper surfaces of the left and right mounting frames have a top groove 26, and a top nut 27 matching its cross section is arranged in the top groove, and the first photovoltaic panel 4 is arranged above the left and right mounting frames, and a pad 28 is arranged between the first photovoltaic panel and the upper surfaces of the left and right mounting frames. The material of the pad can be EPDM, and the bottom surface of the pad has a serrated groove, which acts as a buffer for the top photovoltaic panel. The frame of the first photovoltaic panel 4 is provided with a bolt that passes through the pad from top to bottom and is screwed with the top nut 27, so that the first photovoltaic panel 4 is fixed on the upper surface 7 of the left and right mounting frames, and the bottom nut 24 and the top nut 27 can both be T-nuts.

[0039] The left and right mounting frames pass through the mounting crossbeam 1 through the rectangular through slot 21 and are tightened by the limiting rubber block 22 so that the two can be relatively fixed. The supporting feet 25 screwed to the bottom nuts can top up the left and right mounting frames, that is, in addition to adjusting the contact between the device and the roof, the supporting feet 25 continue to be tightened after contact, so as to lift the front and rear parts of the entire device upward, and cooperate with the downward pressure of the middle crossbeam to play a role of firm fixation. This structure can not only be adjusted according to different positions of the roof, but also make the vehicle photovoltaic deployment device installed on the roof more secure and stable.

[0040] For ease of use, the above-mentioned pulley synchronization mechanism 13 includes two parallel adjustment rods 14 connected between the left and right mounting frames, the ends of the two parallel adjustment rods are fixedly connected with pulleys 15, and a belt 16 is wound between the two pulleys on the same side of the two parallel adjustment rods. Connecting pieces 17 connected to the second photovoltaic panel or the third photovoltaic panel are fixed on the same belt (the two connecting pieces 17 on the same belt are approximately half the length of the belt). The pulley 15 and the belt 16 can both be toothed structures, and the connecting piece is in a crooked shape, one end of which is hooped on the belt, and the other end is fixed on the end face 18 of the second photovoltaic panel or the third photovoltaic panel. The device is installed and fixed at a slightly rearward position of the roof. When unfolded and used, the operator pulls the third photovoltaic panel 6 backward from the handle on the rear side of the third photovoltaic panel 6. While pulling the third photovoltaic panel 6 backward, the pulley synchronization mechanism 13 drives the second photovoltaic panel to be pushed forward, thereby realizing the synchronous action of the second photovoltaic panel and the third photovoltaic panel.

[0041] Furthermore, in order to facilitate the adjustment of the position between the left and right mounting frames, an adjusting knob 19 with a screw is coaxially connected to the parallel adjusting rod on the above-mentioned left and right mounting frames. The adjusting knob 19 penetrates into the inner side from the outer side of the groove 9 in the left and right mounting frames, and a T-shaped nut 20 matching its cross-section is provided in the middle groove. The stud of the adjusting knob 19 is threadedly connected with the internal thread of the T-shaped nut and the internal thread of the end of the parallel adjusting rod 14 in sequence. The parallel adjusting rod not only supports and drives the rotation of the pulley, but also limits the spacing between the left and right mounting frames. By rotating the adjusting knob 19, its relative axial position with the parallel adjusting rod 14 can be adjusted, and the fastening of the adjusting knob 19, the parallel adjusting rod 14 and the left and right mounting frames is achieved by screwing the T-shaped nut in the middle groove of the left and right mounting frames and the stud of the adjusting knob 19.

[0042] Furthermore, for the sake of reasonable design, the first photovoltaic panel, the second photovoltaic panel and the third photovoltaic panel all include a rectangular frame 30 and a photovoltaic component 31 arranged on the rectangular frame. The photovoltaic component 31 includes tempered glass, solar cells and batteries, etc. The rectangular frame 30 and the photovoltaic component 31 can be bonded with glue or packaged and fixed.

[0043] Furthermore, the above-mentioned slide rail is a two-section or three-section pull-out slide rail, preferably a three-section slide rail, which is in the form of a push-button type or a self-locking type to ensure that it will not slide out automatically when not in the unfolded state.

[0044] The installation sequence of the vehicle photovoltaic deployment device of the present invention is to assemble the parts except the first, second and third photovoltaic panels, then install the second photovoltaic panel and the third photovoltaic panel, adjust the left and right spacing of the left and right mounting frames, slide normally back and forth in parallel, then fix the top first photovoltaic panel, and finally place it on the roof, fix the mounting crossbeam 1, and adjust the supporting feet 25 to tighten it.

[0046] The vehicle photovoltaic deployment device of the present invention can be used on a vehicle and can provide a relatively large power supply after being deployed, and the device can be installed stably and reliably.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
