Description

Technical Field

[0001] The utility model relates to the technical field of solar energy utilization, in particular to a telescopic solar power generation sunshade device for automobiles. Background Art

[0002] Converting solar energy into electrical energy through solar panels is a clean and pollution-free power generation method. With the large-scale popularization of new energy vehicles driven by electricity, charging has always been a difficult problem to solve.

[0003] Currently, there is a solar energy device installed on a low-speed electric tricycle. The solar panels in this solar energy device are located on the roof of the electric tricycle and can convert solar energy into electrical energy and store it in a storage battery. However, the current electric vehicles travel at a very high speed. If this solar energy device is installed on the roof of an electric vehicle, it will form a large wind resistance and also affect driving safety.

[0004] The invention patent with the publication number of CN118024977A discloses a seat temperature adjustment system for improving the human comfort in winter and summer applied to a small car. It provides electrical energy through a solar power generation panel installed on the roof and is used for an electric vehicle to provide additional power supply for the electric vehicle, solving the problems that the electric vehicle cannot continuously turn on the air conditioner for heating due to insufficient power in winter and the seat is stuffy and uncomfortable in summer, affecting driving comfort. However, in this application, the solar panels can only cover the roof area, and the shapes of the roofs of different vehicles are also different, resulting in the solar power generation panels not being universal among electric vehicles. After the solar power generation panels are installed, they will also affect the installation or use of the car sunroof. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a telescopic solar power generation sunshade device for automobiles, which is used to solve the problems that the coverage range of the solar power generation panel is small and it is not universal in the background art.

One end of the stretching drive belt is fixedly connected to the end solar panel, and a winch connected to the other end of the stretching drive belt is provided inside the box body.

[0009] Furthermore, the winch includes a stretching drive shaft rotatably connected to the box body and a reduction motor drivingly connected to the stretching drive shaft. The stretching drive belt is wound around the stretching drive shaft, and the reduction motor is fixedly connected to the box body.

[0010] Furthermore, a retracting drive shaft is also rotatably connected inside the box body. The retracting drive shaft is drivingly connected to the stretching drive shaft. A retracting drive belt with one end fixedly connected to it is provided on the end solar panel, and the other end of the retracting drive belt is wound around the retracting drive shaft.

[0011] Furthermore, an outer sleeve is drivingly connected to the outside of the stretching drive shaft through a second one-way bearing, and a stretching synchronous pulley is fixedly connected to the outside of the outer sleeve; an outer sleeve is drivingly connected to the outside of the retracting drive shaft through a first one-way bearing, and a retracting synchronous pulley is provided. A drive synchronous belt is wound around the retracting synchronous pulley and the stretching synchronous pulley, and the retracting synchronous pulley and the stretching synchronous pulley are drivingly connected through the drive synchronous belt; when the reduction motor rotates forward, the outer ring of the second one-way bearing drives the inner ring to rotate synchronously, and the inner ring and the outer ring of the first one-way bearing rotate relative to each other, and the middle solar panel and the end solar panels extend out of the box body and unfold; when the reduction motor rotates reversely, the inner ring and the outer ring of the second one-way bearing rotate relative to each other, and the outer ring of the first one-way bearing drives the inner ring to rotate synchronously, and the middle solar panel and the end solar panels are received into the box body.

[0012] Furthermore, an end slide rail is fixedly connected to the side of the end solar panel, a middle slide rail is fixedly connected to the side of the middle solar panel, the end slide rail, the middle slide rail and the box body are slidably connected in sequence, and the guide wheel is rotatably connected to the middle slide rail.

At the same time, the reduction of the overall volume and the arc-shaped door on the outside reduce the wind resistance generated by the present invention when the vehicle is running. After the vehicle stops, each solar panel extends out and unfolds. Since there is no need to consider blocking the windshield, the extended length of each solar panel can exceed the windshield, increasing the coverage area. Therefore, the size of the solar panel can be made larger, generating more electricity and improving the power generation amount. The unfolded solar panel can also play a role in shading, preventing the temperature inside the vehicle from being too high and prolonging the service life of the vehicle interior and electronic components.

[0032] Embodiment 1

[0033] As Figures 1 to 9 shown, a telescopic solar power generation sunshade device for vehicles includes a box body 6 installed on the top of the vehicle body 1 of the vehicle. The side surfaces of the box body 6 corresponding to the front and rear of the vehicle are open. Two solar panel groups are provided in the box body 6, and the two solar panel groups are evenly distributed at an interval of 180 degrees in the circumferential direction. Each solar panel group includes three solar panels stacked together. Adjacent solar panels in each solar panel group are slidably connected, and the solar panel close to the box body is slidably connected to the box body 6. A solar panel is also installed on the top of the box body 6. An extension drive mechanism for driving each solar panel in each solar panel group to extend and unfold is further provided in the box body 6.

[0034] A long strip-shaped box door 2 is rotatably connected to the outer end of the outermost solar panel. The outer side of the box door 2 is arc-shaped. The inner side of the box door 2 is rotatably connected to the outer end of the corresponding solar panel. The center of gravity of the box door 2 is located outside relative to its rotation center. Therefore, when the solar panel is unfolded, the top of the box door 2 will open outwards under the action of its own weight, thereby preventing the solar panel from being blocked and further affecting the power generation.

[0035] The box body 6 can be installed on the luggage rack of the roof 1 of various automobiles, so that the present invention can be applied to a variety of automobiles, and thus has stronger adaptability.

[0036] As Figure 1 and Figure 2 shown, when the automobile is running, each solar panel is retracted into the box body 6 and stacked, and the box door 2 blocks the openings on both sides of the box body 6, so that the present invention occupies a smaller space and does not affect the use of the automobile sunroof 5. At the same time, the reduction of the overall volume and the box door 2 with an arc-shaped outer side result in less wind resistance when the automobile is running.

[0037] As Figures 3 to 5 shown, when the automobile stops, each solar panel extends and unfolds. Since there is no need to consider blocking the windshield, the unfolded length of each solar panel can exceed the windshield, increasing the coverage area. Therefore, the size of the solar panel can be made larger, generating more electricity and improving the power generation. The unfolded solar panel can also play a role in shading, preventing the temperature inside the automobile from being too high and extending the service life of the automobile interior and electronic components.

[0038] Example calculation:

[0039] The area of the unfolded solar panel is 3.5 square meters (power 680W). Calculated according to 10 hours of parking time during the day every day, the electricity that can be generated is: 0.47 kWh / hour × 10 hours = 4.7 kWh. Calculated according to the ordinary electric vehicle consuming 16 kWh of electricity per 100 kilometers, 4.7 kWh of electricity can travel about 29 kilometers. If the distance traveled to and from work every day does not exceed 29 kilometers, no additional charging is required. (The solar panel with a length of 1.2 meters, a width of 0.604 meters and an area of 0.73 square meters (power 140W) on the top of the box body 6 can be charged for a long time. The charging time of this part is long, and basically electricity can be generated during the lighting time, which is not included.)

[0040] Embodiment 2

[0041] As Figures 3 to 11 shown, the difference between this embodiment and Embodiment 1 is:

[0042] Taking one of the solar panel groups as an example, there are two types of three solar panels in each solar panel group. One of them is the end solar panel 21, and the other two are the middle solar panels 7 that are slidably connected to each other. One of the two middle solar panels 7 is slidably connected to the end solar panel 21, and the other is slidably connected to the box body 6. The box door 2 is rotatably connected to the outside of the end solar panel 21.

[0043] Both the front and rear sides of the end solar panel 21 are fixedly connected with end slide rails 14, and both the front and rear sides of the two middle solar panels 7 are fixedly connected with middle slide rails 3. The positions in the box body 6 corresponding to the middle solar panels 7 are also fixedly connected with middle slide rails 3. The end slide rails 14 are slidably connected with the corresponding middle slide rails 3, and adjacent middle slide rails 3 are slidably connected, so that the end solar panel 21 and the two middle solar panels 7 can be drawn out of the box body 6 and unfolded.

[0044] Grooves are formed in the middle slide rails 3. The stretching drive mechanism includes guide wheels 12 arranged in the grooves of the middle slide rails 3 along the extending direction of the middle solar panels 7 and the end solar panel 21. There are two guide wheels 12 in the middle slide rails 3 corresponding to the middle solar panels 7, and one guide wheel 12 in the middle slide rails 3 corresponding to the box body 6. The stretching drive belt 11 is wound around the guide wheels 12 in a serpentine shape, and the stretching drive belt 11 is located in the grooves of the middle slide rails 3. To prevent the middle slide rails 3 and the end slide rails 14 from separating during sliding, limit blocks are provided on both the middle slide rails 3 and the end slide rails 14.

[0045] As Figure 8 and Figure 9 shown, the right end of the stretching drive belt 11 is fixedly connected to the end slide rail 14 near the left end, then it bypasses the guide wheel 12 at the right end of the right middle slide rail 3 to the left, and then bypasses the guide wheel 12 at the left end of the right middle slide rail 3, the guide wheel 12 at the right end of the middle middle slide rail 3, the guide wheel 12 at the left end of the middle middle slide rail 3, and the guide wheel 12 at the right end of the left middle slide rail 3 in sequence and then winds around the winch 22 in the box body 6.

[0046] Combined with Figure 10 shown, the winch 22 includes a stretching transmission shaft 19 rotatably connected to the front and rear sides of the box body 6 and a reduction motor 9 drivingly connected to the stretching transmission shaft 19. The stretching drive belt 11 is wound around the stretching transmission shaft 19, and the reduction motor 9 is fixedly connected to the box body 6.

[0047] The reduction motor 9 drives the stretching transmission shaft 19 to rotate, pulls the stretching drive belt 11 to the left, and winds the stretching drive belt 11 around the stretching transmission shaft 19. Under the pulling of the stretching drive belt 11, the end solar panel 21 and the two middle solar panels 7 extend out of the box body 6 and unfold, so that the operator can realize the stretching of the end solar panel 21 and the two middle solar panels 7 in the car, and the operation is more convenient.

[0048] Embodiment 3

[0049] As Figures 8 to 11 shown, the difference between this embodiment and Embodiment 2 is that:

[0050] The winch 22 further includes a retracting transmission shaft 18 rotatably connected inside the box body 6. The retracting transmission shaft 18 is in transmission connection with the extending transmission shaft 19, and the retracting transmission shaft 18 is parallel to the extending transmission shaft 19. The left end of the end slide rail 14 is provided with a retracting transmission belt 10 fixedly connected to one end thereof. The other end of the retracting transmission belt 10 is wound around the retracting transmission shaft 18. The winding direction of the retracting transmission belt 10 around the retracting transmission shaft 18 is opposite to the winding direction of the extending transmission belt 11 around the extending transmission shaft 19.

[0051] An inner sleeve 4 is connected to the outside of the extending transmission shaft 19 by a key. A second one-way bearing 8 is sleeved outside the inner sleeve 4. An outer sleeve 13 is sleeved outside the second one-way bearing 8. The extending transmission shaft 19 is in transmission connection with the outer sleeve 13 through the second one-way bearing 8. An extending synchronous pulley 20 is fixedly connected to the outside of the outer sleeve 13. The reduction motor 9 is in transmission connection with the outer sleeve 13.

[0052] A first one-way bearing 17 is sleeved outside the retracting transmission shaft 18. A retracting synchronous pulley 16 is sleeved outside the first one-way bearing 17. The retracting transmission shaft 18 is in transmission connection with the retracting synchronous belt pulley 16 through the first one-way bearing 17. A transmission synchronous belt 15 is wound around the retracting synchronous belt pulley 16 and the extending synchronous pulley 20. The retracting synchronous belt pulley 16 and the extending synchronous pulley 20 are in transmission connection through the transmission synchronous belt 15. Both the first one-way bearing 17 and the second one-way bearing 8 are needle roller one-way bearings.

[0053] In Figure 10 and Figure 11 when the outer ring of the second one-way bearing 8 rotates forward (clockwise when viewed from right to left), it drives the inner ring to rotate synchronously forward. The inner ring and the outer ring of the first one-way bearing 17 rotate relative to each other. When the outer ring of the second one-way bearing 8 rotates backward (counterclockwise when viewed from right to left), the inner ring and the outer ring of the second one-way bearing 8 rotate relative to each other, and the outer ring of the first one-way bearing 17 drives the inner ring to rotate synchronously.

[0054] When the reduction motor 9 drives the outer sleeve 13 to rotate clockwise, it drives the extending transmission shaft 19 to rotate through the second one-way bearing 8, and winds the extending transmission belt 11 on the extending transmission shaft 19. Under the pulling of the extending transmission belt 11, the end solar panel 21 and the middle solar panel 7 extend out of the box body 6 and unfold under the pulling of the extending transmission belt 11. At the same time, under the pulling of the end solar panel 21, the retracting transmission belt 10 drives the retracting transmission shaft 18 to rotate. At this time, the inner ring and the outer ring of the first one-way bearing 17 rotate relative to each other (i.e., slip), so as not to affect the release of the retracting transmission belt 10 from the retracting transmission shaft 18.

[0055] When the reduction motor 9 drives the outer sleeve 13 to rotate counterclockwise, it drives the extension synchronous pulley 20 to rotate, drives the folding synchronous pulley 16 to rotate through the synchronous belt 15, drives the inner ring of the first one-way bearing 17 to rotate synchronously counterclockwise through the outer ring, and then drives the folding transmission shaft 18 to rotate counterclockwise, and rolls the folding transmission belt 10 on the folding transmission shaft 18. Under the pull of the folding transmission belt 10, the end solar panel 21 and the middle solar panel 7 are retracted into the box body 6. At the same time, under the pull of the end solar panel 21, the extension transmission belt 11 drives the extension transmission shaft 19 to rotate. At this time, the inner and outer rings of the second one-way bearing 8 rotate relatively (i.e., slip), so as not to affect the release of the extension transmission belt 11 from the extension transmission shaft 19.

[0056] When the extension transmission belt 11 is wound on the extension transmission shaft 19, the diameter of the extension transmission belt 11 wound on the extension transmission shaft 19 changes. Similarly, the diameter of the folding transmission belt 10 on the folding transmission shaft 18 also changes. The extension transmission belt 1 drives the middle solar panel 7 and the end solar panel 21 through the guide wheel 12, and the folding transmission belt 10 directly pulls the end solar panel 21. All of the above result in different linear speeds of the extension transmission belt 11 and the folding transmission belt 10, and different rotation speeds of the extension transmission shaft 19 and the folding transmission shaft 18. Therefore, the extension transmission shaft 19 and the folding transmission shaft 18 cannot be directly connected and rotated synchronously. By setting the first one-way bearing 17 and the second one-way bearing 8, this technical problem can be perfectly solved.

[0057] In addition, the extension transmission belt 11 and the folding transmission belt 10 can be replaced by other flexible cables, such as steel wire ropes.

[0058] The above-mentioned embodiments describe content in a relatively detailed and specific manner, and express the preferred embodiments of the present utility model. They are only used to illustrate the technical ideas and features of the present utility model, and their purpose is to enable technicians in this field to understand the content of the present utility model and implement it accordingly, but they are not limited to the present utility model. The patent scope of the present utility model cannot be limited only by this embodiment, that is, any equivalent changes or modifications made to the spirit disclosed by the present utility model, for researchers or technicians in this field, without departing from the structure of the present utility model, local improvements within the system and changes and conversions between subsystems, etc., are still within the patent scope of the present utility model.
