Description

Technical Field

[0001] This invention relates to the technical field of unmanned vehicles, and in particular to an on-board solar thin-film charging device, an unmanned vehicle, and a method for deploying the thin film. Background Technology

[0002] As people exploit fossil fuels, the available resources are dwindling, and the pollution they cause to the environment is becoming increasingly severe. Finding new, clean, and efficient energy sources has become an urgent issue. Since the 20th century, people have been researching solar energy, and today, the utilization of solar energy has made unprecedented progress. Currently, not only are large-scale photovoltaic power plants springing up all over the world, but small solar generators, chargers, and other photovoltaic products are also entering people's lives.

[0003] Existing drones have limited flight range during use and require suitable carrier vehicles for delivery. Connecting the drone to the carrier vehicle, and then connecting the carrier vehicle to the client, can effectively increase the drone's operating radius.

[0004] Existing autonomous vehicles have limited built-in power during operation, and the need to move the vehicles back and forth for charging is cumbersome. The charging process also requires the use of battery power, which affects the coverage radius. To solve these problems, the current practice is to add solar panels to the autonomous vehicles. However, the contact area between existing fixed solar panels and sunlight is limited, making it difficult to maintain the power supply of the autonomous vehicles. When using equipment with solar thin films, dust adhering to the film during winding can easily scratch the solar thin film. Therefore, we designed an on-board solar thin film charging device, an autonomous vehicle, and a method for unfolding the film. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, referring to Figures 1 to 4This is the first embodiment of the present invention. This embodiment provides a vehicle-mounted solar film 101 charging device, including a winding roller 100 and a solar film 101 wound on the winding roller 100. The solar film 101 is composed of multiple strip-shaped film sheets 101a connected in series. At least one reset spring 102 is fixedly connected to the bottom of the multiple strip-shaped film sheets 101a. The bottom of the reset spring 102 and the bottom of the solar film 101 are fixedly connected to a positioning tube 103. The positioning tube 103 has a circular cross-section, is made of rubber, and has a thickness of not less than three millimeters. Its thickness ensures that it has the gravitational potential energy to drive the solar film 101 down, so as to facilitate the opening of the solar film 101. The solar film 101 is composed of multiple strip-shaped film sheets 101a, which facilitates its winding while avoiding damage, and at the same time avoids damage due to excessive curling.

[0036] Specifically, refer to Figures 1-3 The reset spring 102 has a flat cross-section and is bonded to the bottom of the solar film 101. Multiple reset springs 102 are arranged in a strip array on the bottom of the solar film 101. The winding roller 100 has a circular cross-section and a hollow interior. The winding roller 100 can be electrically wound and unwound as well as manually wound. A rubber layer 402b is provided on the outer wall of the winding roller 100. The rubber layer 402b effectively protects the solar film 101, preventing damage during winding. The winding roller 100 is bonded to the bottom of the solar film 101. The connection area between the films 101 is made of rubber, which can effectively ensure that the solar film 101 is fully extended. Since the connection between the winding roller 100 and the solar film 101 is outside the sunlight, the use of the solar film 101 as a transition is avoided, which can effectively reduce costs. After the solar film 101 is wound up, its positioning tube 103 can provide gravitational potential energy to supply the stretching force of the solar film 101. At the same time, the reset spring 102 applies to the solar film 101 so that it can be effectively unfolded, thereby increasing the solar area of ​​the solar film 101.

[0037] Reference Figure 3 There are two take-up rollers 100 and two positioning tubes 103. The two positioning tubes 103 are connected by a telescopic mechanism 200. The telescopic mechanism 200 includes a rectangular tube 201. Auxiliary tubes 202 are slidably connected to both sides of the rectangular tube 201. The auxiliary tubes 202 are connected to the ends of the positioning tubes 103 through plugs 203.

[0038] For more information, please refer to [link / reference]. Figures 1-4As shown, the telescopic mechanism 200 connects the two positioning tubes 103 of the device. When the two positioning tubes 103 are connected at the same time, the two telescopic mechanisms 200 and the two positioning tubes 103 form a rectangle, which can give it better wind resistance and prevent the solar film 101 from being damaged by wind. The rectangular tube 201 and the auxiliary tube 202 in the telescopic mechanism 200 are both rectangular, which has good deformation resistance when the device is used. The plug 203 can effectively connect the auxiliary tube 202 and the positioning tube 103.

[0039] The reset spring 102 is flat. Multiple strip-shaped thin films 101a in the solar thin film 101 are connected by rubber material. The rubber material allows adjacent strip-shaped thin films 101a to twist, which is convenient for the winding roller 100 to receive them. The strip-shaped thin films 101a are elastic. During the winding process, the strip-shaped thin films 101a bends towards the winding roller 100. When released, the strip-shaped thin films 101a twists downward. The bending angle between two adjacent strip-shaped thin films 101a is greater than 120° to avoid damage to the connection effect between the strip-shaped thin films 101a due to excessive twisting, while ensuring that the solar thin film 101 composed of multiple strip-shaped thin films 101a can be unfolded normally.

[0040] When the take-up roller 100 releases the solar film 101, the take-up roller 100 rotates outward, causing the solar film 101 to move away from the take-up roller 100. During the movement of the solar film 101, the positioning tube 103 descends under the action of gravitational potential energy, and the matching reset spring 102 causes the solar film 101 in the device to bend and unfold. After both sides of the solar film 101 have been unfolded, the telescopic mechanism 200 is connected to the positioning tube 103 to limit the positioning tube 103. After the positioning tube 103 is limited, the solar film 101 can be limited, thereby completing the fixation of the solar film 101.

[0041] In summary, this device can effectively release and retract the solar film 101 during use, providing a larger unfolding area compared to the existing fixed solar panel 701. Furthermore, when not in use, it can effectively roll up and protect the solar film 101, preventing damage from external impacts. The solar film 101 is placed in an arc shape when unfolded, allowing the device's orientation to be adjusted according to the angle of sunlight, enabling it to effectively receive sunlight.

[0042] Example 2, refer to Figures 1-9This is the second embodiment of the present invention. Unlike the previous embodiment, the film cleaning mechanism 400 is included. This embodiment includes a carriage 300, a winding roller 100 installed inside the carriage 300, and a drive handle passing through the carriage 300 and rotatably connected to it. External seams 301 are provided on both sides of the carriage 300, and the film cleaning mechanism 400 is installed on the top of the external seams 301.

[0043] Furthermore, the drive handle is rotatably connected to the carriage 300 via bearings. The drive handle can be used in case of power failure of the take-up roller 100 or in an emergency. The outer seam 301 is used for the passage of the solar film 101. The outer seam 301 is flat and the solar film 101 is located on both sides of the carriage 300.

[0044] The film cleaning mechanism 400 includes a positioning box 401 with an open bottom. A cleaning roller 402 is placed at the opening of the positioning box 401, and a squeezing tube 403 is assembled between the cleaning roller 402 and the positioning box 401. The squeezing tube 403 has arc-shaped upper and lower sides and a fan-shaped cross-section.

[0045] The positioning box 401 effectively accommodates the materials inside. Its opening faces vertically downwards. The cleaning roller 402 rolls in contact with the solar film 101 during operation. The extrusion tube 403 increases the contact force between the cleaning roller 402 and the solar film 101, ensuring close contact and sliding between the solar film 101 and the cleaning roller 402. The cleaning roller 402 can remove dust from the outer wall of the solar film 101, thereby ensuring the cleanliness of the outer wall of the solar film 101.

[0046] The cleaning roller 402 includes an inner cylinder 402a, a rubber layer 402b fixedly connected to the outer wall of the inner cylinder 402a, a sponge layer 402c fixedly connected to the outside of the rubber layer 402b, and a cotton net 402d fixedly connected to the outer wall of the sponge layer 402c. The cotton net 402d tightly wraps the sponge layer 402c, causing the sponge layer 402c to protrude from the gaps in the cotton net 402d. The top of the inner wall of the positioning box 401 is provided with an arc-shaped groove 401a, and the bottom of the inner wall of the positioning box 401 is provided with a hook plate 401b. An isolation chamber 401c is formed between the hook plate 401b and the inner wall of the positioning box 401. The arc-shaped groove 401a is in contact with the outer wall of the extrusion tube 403, and the bottom of the extrusion tube 403 is in contact with the outer wall of the cleaning roller 402.

[0047] Specifically, the inner cylinder 402a is made of metal, which has a certain gravitational potential energy, ensuring that the outer wall of the cleaning roller 402 can effectively contact the solar film 101 and maintain contact with its outer wall, thus ensuring contact pressure between the roller and the solar film 101. This facilitates the removal of dust from the outer wall of the solar film 101. The cotton mesh 402d is used to divide the sponge layer 402c into multiple protrusions, thereby better removing dust. At the same time, during the rotation of the cleaning roller 402, the dust attached to the sponge layer 402c can be scraped off by the hook plate 401b. After the dust is scraped off from the sponge layer 402c, the cleanliness of the outer wall of the cleaning roller 402 can be effectively maintained, thus better removing dust from the outer wall of the solar film 101.

[0048] The rest of the structure is the same as in Example 1.

[0049] During use, as the solar film 101 moves outward or inward through the outer seam 301, the top of the solar film 101 contacts the bottom of the cleaning roller 402. As the cleaning roller 402 moves upward, it rotates under the friction of the solar film 101, causing the dust on the solar film 101 to adhere to the cleaning roller. At the same time, during the rotation of the cleaning roller 402, the dust attached to the sponge layer 402c can be scraped off by the hook plate 401b. After the dust is scraped off from the sponge layer 402c, the cleanliness of the outer wall of the cleaning roller 402 can be effectively guaranteed. The scraped-off dust enters the isolation chamber 401c.

[0050] In summary, this device can clean the outer surface of the solar film 101 during use, preventing damage to the surface of the solar film 101 caused by dust compression and friction during winding, and further ensuring the working efficiency of the solar film 101. The cleaning mechanism can effectively collect the adhering dust, ensuring the cleanliness of the cleaning roller 402 in the cleaning mechanism, and can effectively remove dust from the surface of the solar film 101.

[0051] Example 3, referring to Figures 1-2 This is the third embodiment of the present invention. Unlike the previous embodiment, an unmanned vehicle includes a vehicle body 300, a chassis 500 installed at the bottom of the vehicle body 300, and a drone carrier platform 600 installed on the top of the vehicle body 300. An arc-shaped top cover 700 is installed on the top of the drone carrier platform 600, and a solar panel 701 is attached to the outer wall of the arc-shaped top cover 700. The arc-shaped top cover 700 is hinged to the drone carrier platform 600, and a protective plate 501 is installed on the outside of the chassis 500.

[0052] The device includes a drone carrier platform 600 that provides a take-off and landing platform for drones. When the device carries the drone for transport, it can increase the drone's operating distance. The arc-shaped top cover 700 is used to protect the drone carrier platform 600 from wind and rain, while the solar panel 701 can provide power to the drone.

[0053] The rest of the structure is the same as in Example 2.

[0054] Example 4, refer to Figures 1-4 This is the fourth embodiment of the present invention. Unlike the previous embodiment, a thin film unfolding method includes driving a take-up roller 100 to rotate toward a positioning tube 103 to release the solar film 101. When the solar film 101 is released, the positioning tube 103 drives the solar film 101 to move downward. Under the limiting action of the reset spring 102 located at the bottom of the solar film 101, the solar film 101 is driven to unfold in a curved shape. After the solar film 101 is fully unfolded, the two positioning tubes 103 are spliced ​​and fixed by two telescopic mechanisms 200, so that the positioning tubes 103 and the solar film 101 can be limited at the same time.

[0055] The rest of the structure is the same as in Example 3.
