Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging, and in particular to a solar charging device for a vehicle battery. Background Art

[0002] When the car starts, it needs to use the power supply in the vehicle battery to provide electricity. Therefore, in order to ensure that the car can start normally, the vehicle battery must have sufficient power. After the car starts, the vehicle engine can drive the generator to charge the vehicle battery.

[0003] After searching, the invention patent with authorization announcement number CN114039531 B discloses a solar charging device for vehicle batteries, which solves the problem that existing charging devices cannot be conveniently and stably extended and installed and subsequently disassembled and folded during operation. Therefore, when the vehicle encounters bumps during driving, it is very easy to cause vibration damage to the charging device, and thus cannot ensure the safety of the charging device during use and the convenience of subsequent folding and storage.

[0004] However, the above device still has some shortcomings. The most obvious one is that during the use of the device, the relevant users need to manually unfold and store the protective components, which not only increases the difficulty of use, but also the unfolding and storage process of the protective components is relatively cumbersome and not convenient to use. In addition, the flexible protective cloth in the protective component has limited protective effect due to its own characteristics, and cannot provide sufficient protection for the easily damaged solar panels during actual application.

[0005] In addition, when using the above-mentioned device, it needs to be unfolded first and then placed on the top of the vehicle. However, since the unfolded device is relatively large, the difficulty of subsequent picking up and placing it is further increased.

[0006] Therefore, it is necessary to invent a vehicle battery solar charging device to solve the above problems. Summary of the Invention

It does not require manual deployment, placement and protection of photovoltaic panels. In addition, it has a better protective effect on photovoltaic panels, so as to solve the problem that during the use of the device proposed in the above background technology, relevant users need to manually deploy and store the protective components, which not only increases the difficulty of use, but also the deployment and storage process of the protective components is relatively cumbersome and not convenient to use.

[0018] Preferably, a method for using the solar charging device for a vehicle battery is also included, the method specifically comprising the following steps:

[0019] S1. Pick up the box using the handle on the middle right side of the box and place it in a suitable position on top of the vehicle. The four electromagnetic suction cups at the bottom of the box are now attached to the top of the vehicle. Then, four electromagnetic control switches are used to turn on the four electromagnetic suction cups, causing them to adhere to the top of the vehicle, thereby securing the box. The photovoltaic panels are now housed in the hard protective shell formed by the box and the cover.

[0020] S2. The electric push rod drives its output shaft to retract, that is, the electric push rod drives the end plate to continuously move right inside the shell. When the end plate moves right, it drives the mounting slot and rack A to move right synchronously through the movable plate. When rack A moves right, it drives the adjacent gear A to rotate counterclockwise, and then gear A drives the rotating block to rotate counterclockwise through the rotating shaft A.

At the same time, gear B engages with gear D due to the rotation of the wiring tube.

[0022] S4. As the movable plate continues to move right, gear D drives gear B to rotate continuously. Gear B then drives the cover to rotate through the wiring tube. The cover then drives the photovoltaic panel to rotate synchronously until the photovoltaic panel facing right rotates to face left. At this time, the limit flange is in contact with the outer wall of the box and is blocked by the outer wall of the box. At the same time, rack B is engaged with gear A.

[0023] S5. Rack B continues to move rightward under the drive of the moving plate, causing the rotating block to drive the cover to reset clockwise until the cover fits on the top of the box. At this time, the photovoltaic panel is located on the top of the cover and absorbs solar energy and converts it into electricity stored in the power supply battery.

[0024] S6. When the photovoltaic panel needs to be protected or stored during use, the electric push rod drives the end plate to move left and reset, and then the cover drives the photovoltaic panel to stand upright and rotate to its original position again, and then rotates to a horizontal state. At this time, the photovoltaic panel is once again stored in the hard protective shell composed of the box and the cover.

[0025] Technical effects and advantages of the present invention:

[0026] The present invention is provided with a solar charging component, a first flip component and a second flip component, so that under normal conditions, the photovoltaic panel can be stored in a hard protective shell composed of a box body and a cover body, thereby obtaining good protection. When the photovoltaic panel needs to be used, the first flip component can be used in conjunction with the second flip component to drive the solar charging component, so that the photovoltaic panel can complete the operations of erecting, rotating and resetting in sequence to achieve unfolding. In addition, the device does not need to be manually unfolded when in use, and can be directly placed on the top of the vehicle.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] The present invention provides Figure 1-Figure 5 The solar charging device for a vehicle battery shown in the figure includes a storage component 1, a solar charging component 2 is arranged on the top of the storage component 1, a first flip component 3 is arranged on the left side of the top of the solar charging component 2, a second flip component 4 is arranged inside the storage component 1 and the first flip component 3, and a shielding and avoiding component 5 is arranged inside the first flip component 3.

[0036] like Figure 2As shown, the storage component 1 includes a box body 11, which is made of high-strength lightweight alloy, which not only ensures structural rigidity but also reduces the overall weight. A humanized handle is provided in the middle of the right side for easy carrying. Electromagnetic suction cups 12 are fixedly nested at the four corners of the bottom of the box body 11, and electromagnetic control switches 13 are fixedly provided at the four corners inside the box body 11. The four electromagnetic control switches 13 are respectively located on the top of the four electromagnetic suction cups 12 and respectively control the opening and closing of the four electromagnetic suction cups 12. A power supply battery 14 is provided inside the box body 11, and the power supply battery 14 is a high-capacity lithium battery. A plurality of fixing brackets 15 fixedly connected to the inner wall of the box body 11 are provided on the outside of the power supply battery 14. The fixing bracket 15 is lined with a rubber buffer layer, which can reduce the impact of vehicle bumps on the battery. A wiring hole B is provided at the bottom of the box body 11, and the power supply battery 14 charges the vehicle-mounted battery by passing through the wiring hole B.

[0037] By setting up the above structure, the box 11 can be picked up through the handle in the middle of the right side of the box 11 and placed in a suitable position on the top of the vehicle. At this time, the four electromagnetic suction cups 12 at the bottom of the box 11 are attached to the top surface of the vehicle. Then, the four electromagnetic suction cups 12 are turned on by four electromagnetic control switches 13, and the four electromagnetic suction cups 12 are adsorbed on the metal top of the vehicle, thereby fixing the box 11. In addition, the photovoltaic panel 210 is stored in the hard protective shell composed of the box 11 and the cover 29, and can be well protected.

[0038] like Figure 2 and Figure 3 As shown, the solar charging assembly 2 includes a U-shaped frame 21 fixedly arranged on the left side of the top of the box body 11, and inner magnetic rings 22 are fixedly arranged at both ends of the outer side of the U-shaped frame 21, and rotating shafts A23 are rotatably nested at both ends of the inner side of the U-shaped frame 21 through bearings. The rotating shaft A23 is located on the inner side of the inner magnetic ring 22 and its outer side is fixedly sleeved with outer magnetic rings 24 that are magnetically attracted to the adjacent inner magnetic rings 22 and gears A25. A rotating block 26 is fixedly arranged between the two rotating shafts A23, and a wiring tube 27 is rotatably penetrated through the middle part of the right side of the rotating block 26 through a bearing. A gear B28 is fixedly sleeved on the outer left end of the wiring tube 27, and a cover 29 is fixedly sleeved on the outer right end of the wiring tube 27. The cover 29 is made of hard engineering plastic and has both waterproof and impact resistance. A photovoltaic panel 210 connected to the power supply battery 14 through a wire is fixedly arranged on the inside of the cover 29.

[0039] By setting the above structure, when the gear A25 rotates counterclockwise, the rotating block 26 is driven to rotate counterclockwise through the rotating shaft A23. When the rotating block 26 rotates, the cover body 29 is driven to rotate synchronously through the wiring tube 27, and then the cover body 29 drives the photovoltaic panel 210 to gradually rotate from a horizontal state attached to the top of the box body 11 to a vertical state perpendicular to the box body 11. Subsequently, the gear B28 drives the cover body 29 to rotate through the wiring tube 27, and the cover body 29 drives the photovoltaic panel 210 to rotate synchronously until the photovoltaic panel 210 facing the right is rotated to face the left.

[0040] In addition, during the rotation of the rotation axis A23, the outer magnetic ring 24 rotates synchronously driven by the rotation axis A23, and continues to be adsorbed with the adjacent inner magnetic ring 22, so that when the photovoltaic panel 210 is unfolded or stored to a specified angle, the inner magnetic ring 22 and the outer magnetic ring 24 are tightly adsorbed to provide additional positioning force to avoid angle deviation.

[0041] like Figure 3 As shown, a wiring groove 211 is provided at the bottom of the gear A25, a wiring hole A212 is provided through the rotating block 26, and positioning magnets 213 are fixedly nested at both ends of the right side of the gear A25 and both ends of the left side of the gear B28.

[0042] By setting up the above structure, the wires connecting the power supply battery 14 and the photovoltaic panel 210 can enter from the opening at the right end of the wiring tube 27, then be arranged along the inner cavity of the wiring tube 27 and pass through the wiring hole A212, and finally enter the interior of the box 11 from the bottom opening of the wiring groove 211 and connect with the power supply battery 14, thereby avoiding excessive twisting of the wires when the photovoltaic panel 210 rotates.

[0043] like Figure 4 and Figure 5 As shown, the first flip assembly 3 includes a shell 31 fixedly sleeved on the left side of the box body 11, and avoidance grooves A32 adapted to the movable plate 35 are provided at both ends of the right side of the shell 31. The first flip assembly 3 also includes an electric push rod 33 fixedly provided on the inner wall of the box body 11. The electric push rod 33 adopts a high-precision electric push rod with a stroke accuracy of ±0.5mm. The output shaft of the electric push rod 33 extends to the left side of the box body 11 and is fixedly connected to the end plate 34. The movable plate 35 is fixedly provided at both ends of the end plate 34. A mounting groove 36 is provided on the inner side of the movable plate 35. A rack A37 is fixedly provided at the bottom inside the mounting groove 36 and a rack B38 is fixedly provided at the top inside the mounting groove. The rack A37 is engaged with the adjacent gear A25.

[0044] By setting the above structure, the electric push rod 33 can drive its output shaft to retract, that is, the electric push rod 33 drives the end plate 34 to continuously move to the right inside the shell 31. When the end plate 34 moves to the right, the mounting groove 36 and the rack A37 are driven to move to the right synchronously through the movable plate 35. When the rack A37 moves to the right, it drives the adjacent gear A25 to rotate counterclockwise. In addition, when the rack B38 continues to move to the right driven by the movable plate 35, the rack B38 engaged with the gear A25 causes the rotating block 26 to drive the cover body 29 to reset clockwise until the cover body 29 is attached to the top of the box body 11. At this time, the photovoltaic panel 210 is located on the top of the cover body 29 and absorbs solar energy and converts it into electrical energy that exists inside the power supply battery 14.

[0045] like Figure 2 and Figure 5 As shown, the second flip assembly 4 includes a rotating shaft B41 which is nested and rotatably arranged on the left side of the box body 11 through a bearing, and a gear C42 and a gear D43 are fixedly sleeved on the outside of the rotating shaft B41 from bottom to top. The second flip assembly 4 also includes a mounting shaft 44 fixedly arranged on the bottom right side of the end plate 34, and a rack C45 meshing with the gear C42 is slidably sleeved on the right end of the outer side of the mounting shaft 44. An avoidance groove B is opened on the left side of the box body 11, and the rack C45 is slidably arranged on the inner side of the avoidance groove B. A reset spring A46 fixedly connected between the end plate 34 and the rack C45 is sleeved on the outer side of the mounting shaft 44, and a limiting flange 47 is fixedly sleeved on the outer side of the rack C45.

[0046] By setting up the above structure, when the end plate 34 moves to the right, the rack C45 is driven to move to the right synchronously through the installation shaft 44 and the return spring A46, and the rack C45 drives the gear D43 to rotate continuously through the gear C42 and the rotating shaft B41. When the gear B28 engages with the gear D43 due to the rotation of the wiring tube 27, as the movable plate 35 continues to move to the right, the gear D43 drives the gear B28 to rotate continuously until the limiting flange 47 is in contact with the outer wall of the box body 11 and is blocked by the outer wall of the box body 11, thereby ensuring that the wiring tube 27 drives the cover body 29 to rotate into place while avoiding excessive rotation of the cover body 29.

[0047] The present invention also provides a method for using a solar charging device for a vehicle battery, the method specifically comprising the following steps:

[0048] S1. Pick up the box 11 using the handle on the middle right side of the box 11 and place it in a suitable position on the top of the vehicle. The four electromagnetic suction cups 12 on the bottom of the box 11 are then attached to the top of the vehicle. Then, the four electromagnetic control switches 13 are used to turn on the four electromagnetic suction cups 12, causing them to adhere to the top of the vehicle, thereby securing the box 11. The photovoltaic panel 210 is now housed in the hard protective casing formed by the box 11 and the cover 29.

[0049] S2. The electric push rod 33 drives its output shaft to retract, that is, the electric push rod 33 drives the end plate 34 to continuously move rightward inside the housing 31. When the end plate 34 moves rightward, it drives the mounting slot 36 and the rack A37 to move rightward synchronously through the movable plate 35. When the rack A37 moves rightward, it drives the adjacent gear A25 to rotate counterclockwise, thereby causing the gear A25 to drive the rotating block 26 to rotate counterclockwise through the rotating shaft A23. When the rotating block 26 rotates, it drives the cover 29 to rotate synchronously through the wiring tube 27, thereby causing the cover 29 to drive the photovoltaic panel 210 to gradually rotate from a horizontal state attached to the top of the box body 11 to a vertical state perpendicular to the box body 11;

[0050] S3. When the end plate 34 moves to the right, the rack C45 is driven to move to the right synchronously through the mounting shaft 44 and the return spring A46. The rack C45 then drives the gear D43 to rotate continuously through the gear C42 and the rotating shaft B41. When the photovoltaic panel 210 rotates to the vertical position, the rack A37 is disengaged from the gear A25. At the same time, the gear B28 is engaged with the gear D43 due to the rotation of the wiring tube 27.

[0051] S4. As the movable plate 35 continues to move rightward, the gear D43 drives the gear B28 to rotate continuously. The gear B28 then drives the cover 29 to rotate through the wiring tube 27. The cover 29 then drives the photovoltaic panel 210 to rotate synchronously until the photovoltaic panel 210 facing rightward rotates to face leftward. At this time, the limiting flange 47 is in contact with the outer wall of the box 11 and is blocked by the outer wall of the box 11. At the same time, the rack B38 is engaged with the gear A25.

[0052] S5. Driven by the moving plate 35, the rack B38 continues to move rightward, causing the rotating block 26 to drive the cover 29 to reset clockwise until the cover 29 is attached to the top of the box 11. At this time, the photovoltaic panel 210 is located on the top of the cover 29 and absorbs solar energy and converts it into electrical energy stored in the power supply battery 14.

[0053] S6. When the photovoltaic panel 210 needs to be protected or stored during use, the electric push rod 33 drives the end plate 34 to move left and reset, and then the cover 29 drives the photovoltaic panel 210 to be vertical and rotated to the original position again, and then rotated to a horizontal state. At this time, the photovoltaic panel 210 is again stored in the hard protective shell composed of the box body 11 and the cover body 29.

[0054] Example 2

[0055] Different from the above embodiment, Figure 4As shown, the shielding avoidance component 5 includes a fixed plate 51 fixedly arranged on the top of the inner cavity of the shell 31, and sliding shafts 52 are slidingly provided at both ends of the right side of the fixed plate 51. A shielding plate 53 is fixedly provided at the right ends of the two sliding shafts 52. The shielding plate 53 slides and fits on the top of the U-shaped frame 21, and a return spring B54 is fixedly provided on the outer side of the sliding shaft 52 and is fixedly connected between the fixed plate 51 and the shielding plate 53.

[0056] By setting the above structure, when the rotating block 26 and the cover body 29 are in a horizontal state, the baffle plate 53 can block the top of the U-shaped frame 21, thereby preventing rainwater or foreign objects from directly entering the interior of the box body 11. When the rotating block 26 rotates, the rotating block 26 can push the baffle plate 53 to the left. At this time, the baffle plate 53 drives the sliding shaft 52 to move left on the fixed plate 51 and compresses the return spring B54 to avoid it.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.

10. The solar charging device for vehicle batteries according to claim 7, characterized in that: The invention also includes a method for using the solar charging device for a vehicle battery, the method specifically comprising the following steps: S1. The box (11) is taken up through the handle on the middle right side of the box (11) and placed at a suitable position on the top of the vehicle. At this time, the four electromagnetic suction cups (12) at the bottom of the box (11) are attached to the top surface of the vehicle. Then, the four electromagnetic suction cups (12) are turned on through four electromagnetic control switches (13), so that the four electromagnetic suction cups (12) are adsorbed on the top of the vehicle, thereby fixing the box (11). At this time, the photovoltaic panel (210) is stored in the hard protective shell composed of the box (11) and the cover (29); S2, the electric push rod (33) drives its output shaft to retract, that is, the electric push rod (33) drives the end plate (34) to continuously move rightward inside the housing (31), and when the end plate (34) moves rightward, it drives the mounting groove (36) and the rack A (37) to move rightward synchronously through the moving plate (35), and when the rack A (37) moves rightward, it drives the adjacent gear A (25) to rotate counterclockwise, thereby causing the gear A (25) to drive the rotating block (26) to rotate counterclockwise through the rotating shaft A (23), and when the rotating block (26) rotates, it drives the cover (29) to rotate synchronously through the wiring tube (27), thereby causing the cover (29) to drive the photovoltaic panel (210) to gradually rotate from a horizontal state attached to the top of the box (11) to a vertical state perpendicular to the box (11); S3, when the end plate (34) moves to the right, the rack C (45) is driven to move to the right synchronously through the mounting shaft (44) and the return spring A (46), and the rack C (45) drives the gear D (43) to rotate continuously through the gear C (42) and the rotating shaft B (41). When the photovoltaic panel (210) rotates to a vertical state, the rack A (37) is disengaged from the gear A (25), and the gear B (28) is also engaged with the gear D (43) due to the rotation of the wiring tube (27); S4. As the moving plate (35) continues to move right, the gear D (43) drives the gear B (28) to rotate continuously, and the gear B (28) drives the cover (29) to rotate through the wiring tube (27), and the cover (29) drives the photovoltaic panel (210) to rotate synchronously until the photovoltaic panel (210) facing the right is rotated to face the left. At this time, the limiting flange (47) is in contact with the outer wall of the box (11) and is blocked by the outer wall of the box (11), and the rack B (38) is engaged with the gear A (25); S5, the rack B (38) continues to move rightward under the drive of the moving plate (35), thereby causing the rotating block (26) to drive the cover (29) to reset clockwise until the cover (29) is attached to the top of the box (11). At this time, the photovoltaic panel (210) is located on the top of the cover (29) and absorbs solar energy and converts it into electrical energy stored in the power supply battery (14); S6. When the photovoltaic panel (210) needs to be protected or stored during use, the electric push rod (33) drives the end plate (34) to move leftward and reset, and then the cover (29) drives the photovoltaic panel (210) to be vertical and rotated to the original position again, and then rotated to a horizontal state. At this time, the photovoltaic panel (210) is once again stored in the hard protective shell composed of the box (11) and the cover (29).
