[0023] This invention proposes a roof solar charging device.

[0024] Referring to Fig. 1 to Fig. 4, Fig. 1 is a schematic diagram 1 of an embodiment of a vehicle according to the present invention. Fig. 2 is a schematic diagram 2 of an embodiment of a vehicle according to the present invention. Fig. 3 is a schematic diagram 1 of an embodiment of a roof solar charging device according to the present invention. Fig. 4 is a schematic diagram 1 of a part of an embodiment of a roof solar charging device according to the present invention.

[0025] In one embodiment of the present invention, the roof solar charging device comprises: a housing 100 for being fixed to the top of a vehicle body; A cover body 200 is provided on the side of the housing 100 opposite to the vehicle body; an opening / closing device 300 that is provided on one of the housing 100 and the lid 200 and is drivingly connected to the other of the housing 100 and the lid 200, thereby engaging or separating the lid 200 and the housing 100, engaging the lid 200 and the housing 100 to form a storage space, and separating the lid 200 and the housing 100 to open the storage space; A battery 400 provided inside the storage space; The storage space includes a first solar panel assembly 500 electrically connected to the battery 400 and having a stored state in which it is stored inside the storage space and a deployed state in which it is deployed outside the storage space, the storage space being opened so that the first solar panel assembly 500 can be switched between the stored state and the deployed state.

[0026] The roof solar charging device in the technical solution of the present invention includes a housing 100, a cover body 200, a battery 400, an opening and closing device 300 and a first solar panel assembly 500, where the housing 100 is fixed to the top of the vehicle body, and the opening and closing device 300 drives the cover body 200 to move relative to the housing 100, and can engage the cover body 200 and the housing 100 to form an accommodation space, or separate the cover body 200 and the housing 100 to open the accommodation space. When the opening / closing device 300 drives the cover body 200 to open the storage space, the first solar panel assembly 500 can be switched between a stored state and an deployed state. In the deployed state, the first solar panel assembly 500 is deployed outside the storage space, converts solar energy into electrical energy, and transports the generated electrical energy to the battery 400 for storage. The electrical energy in the battery 400 can be used as a backup power source for the vehicle's power battery, thereby extending the vehicle's cruising range and reducing the possibility of the vehicle being parked outdoors. In the stored state, the first solar panel assembly 500 is stored inside the storage space, saving the space occupied by the first solar panel assembly 500 and reducing the impact of the first solar panel assembly 500 on the appearance and usage performance of the vehicle. In addition, when the first solar panel assembly 500 is in a stored state and the cover body 200 is engaged with the housing 100, the housing 100 and the cover body 200 provide protection for the battery 400 and the first solar panel assembly 500 in the storage space, preventing damage to the battery 400 and the solar panel caused by external environments such as rain, snow, dust, and branches and leaves, and extending the service life of the roof solar charging equipment.

[0027] Here, the opening / closing device 300 can realize the opening and closing of the lid body 200 by moving and driving the lid body 200 in a number of forms, such as a motor and an electric push rod. The battery 400 is fixed inside the accommodating space, and the battery 400 may be attached to the housing 100 or the lid body 200. Since the housing 100 is fixed to the vehicle body and the lid body 200 moves relative to the housing 100, by providing the battery 400 to the housing 100, the battery 400 can be attached more firmly and the load requirement of the opening / closing device 300 can be reduced.

[0028] In one embodiment, the first solar panel assembly 500 comprises: A horizontal solar panel 510 that is rotatably connected to the housing 100 and electrically connected to the battery 400, and that is accommodated in the accommodation space by its own rotation or deployed outside the accommodation space along the width direction of the vehicle body; The solar panel 520 is rotatably connected to the housing 100 and electrically connected to the battery 400, and is accommodated inside the storage space by rotating itself, or is deployed outside the storage space along the longitudinal direction of the vehicle body.

[0029] 1, in the embodiment of the present invention, the first solar panel assembly 500 includes a horizontal solar panel 510 and a vertical solar panel 520, both of which are rotatably connected to the housing 100, and the horizontal solar panel 510 can be deployed outside the housing 100 along the width direction of the vehicle by rotating itself, and the vertical solar panel 520 can be deployed outside the housing 100 along the vertical direction of the vehicle by rotating itself. By installing the horizontal solar panel 510 and the vertical solar panel 520, the total area of ​​the first solar panel assembly 500 that receives solar is increased, the solar absorption efficiency is improved, and the utilization rate of the top space of the vehicle is improved.

[0030] Specifically, referring to Fig. 1, one horizontal solar panel 510 is provided on each side of the housing 100 along the vehicle width direction, and the width of each horizontal solar panel 510 is slightly smaller than half the width of the housing 100. One vertical solar panel 520 is provided on each side of the housing 100 along the vehicle length direction, and combining Fig. 1 and Fig. 5, the vertical solar panel 520 includes a plurality of sub-solar panels connected at the head and tail and capable of being inverted and folded, and the width of each sub-solar panel is slightly smaller than half the length of the housing 100. By providing a plurality of sub-solar panels that can be inverted and folded, the area of ​​the vertical solar panel 520 is increased, the absorption efficiency of the first solar panel assembly 500 is further improved, and the utilization rate of the space on the top of the vehicle is further improved. Specifically, in this embodiment, the vertical solar panel 520 deployed toward the front of the vehicle includes five sub-solar panels, and the vertical solar panel 520 deployed toward the rear of the vehicle includes four sub-solar panels, which cover a large area of ​​the top of the vehicle and provide a shading function for the vehicle to prevent the temperature inside the vehicle from overheating at high temperatures. The size of each sub-solar panel is the same as the size of the horizontal solar panel 510, which reduces the number of parts of the first solar panel assembly 500 and improves processing efficiency and assembly efficiency. Here, when the horizontal solar panel 510 and the vertical solar panel 520 are both accommodated inside the accommodation space, the horizontal solar panel 510 may be stacked above the vertical solar panel 520, or the vertical solar panel 520 may be stacked above the horizontal solar panel 510.

[0031] In one embodiment, the roof solar charging device further includes a first traction tool 610 made of a flexible material, one end of the first traction tool 610 is connected to the housing 100, and the other end of the first traction tool 610 is connected to the cover body 200 or the opening and closing device 300. During the process of the cover body 200 opening the storage space, the first traction tool 610 drives the lateral solar panel 510 to rotate in a direction away from the storage space, and / or The roof solar charging equipment further includes a second pulling device 620 made of a flexible material, one end of the second pulling device 620 is connected to the housing 100, and the other end of the second pulling device 620 is connected to the cover body 200 or the opening and closing device 300. During the process of the cover body 200 opening the storage space, the second pulling device 620 drives the vertical solar panel 520 to rotate in a direction away from the storage space.

[0032] Referring to Figures 5 to 9, in an embodiment of the present invention, the roof solar charging equipment further includes a first traction device 610, which may take the form of a rope, wire, belt, chain, etc., and is made of a flexible material such as fiber, rubber, etc., so that the first traction device 610 is flexible. One end of the first traction device 610 is connected to the housing 100, and the other end of the first traction device 610 is connected to the cover body 200 or the opening and closing device 300. In the process of the opening and closing device 300 driving the cover body 200 to open the storage space, the first traction device 610 moves together with the cover body 200 or the opening and closing device 300, and drives the horizontal solar panel 510 to rotate in a direction away from the storage space, so as to tilt the horizontal solar panel 510 at a certain angle, thereby realizing a semi-deployment effect, which facilitates the user's manual operation to continue deploying the horizontal solar panel 510, saves time and effort, and improves the convenience of the user when deploying the horizontal solar panel 510. In addition, the structure of the first traction device 610 is simple, easy to manufacture, and has a low production cost. Specifically, in this embodiment, when the lid body 200 closes the storage space, the distance between the lid body 200 and the housing 100 is relatively small, and the first traction device 610 is folded in half on both sides of the horizontal solar panel 510, and as the lid body 200 opens, the distance between the lid body 200 and the housing 100 increases, and the first traction device 610 is gradually tightened, rotating the horizontal solar panel 510 in a direction away from the storage space.

[0033] Referring to Figures 5 to 9, in an embodiment of the present invention, the roof solar charging equipment further includes a second traction device 620, which may take the form of a rope, wire, belt, chain, etc., and is made of a flexible material such as fiber, rubber, etc., so that the second traction device 620 is flexible. One end of the second traction device 620 is connected to the housing 100, and the other end of the second traction device 620 is connected to the cover body 200 or the opening and closing device 300. In the process of the opening and closing device 300 driving the cover body 200 to open the storage space, the second traction device 620 moves together with the cover body 200 or the opening and closing device 300, and drives the vertical solar panel 520 to rotate in a direction away from the storage space, so as to tilt the vertical solar panel 520 at a certain angle, thereby realizing a semi-deployment effect, which facilitates the user's manual operation to continue deploying the vertical solar panel 520, saves time and effort, and improves the convenience of the user when deploying the vertical solar panel 520. In addition, the structure of the second traction device 620 is simple, easy to manufacture, and has a low production cost. Specifically, in this embodiment, when the lid body 200 closes the storage space, the distance between the lid body 200 and the housing 100 is relatively small, and the second pulling device 620 is folded in half on both sides of the vertical solar panel 520, and as the lid body 200 opens, the distance between the lid body 200 and the housing 100 increases, and the second pulling device 620 is gradually tightened, rotating the vertical solar panel 520 in a direction away from the storage space.

[0034] Here, the lengths and installation positions of the first and second pulling tools 610 and 620 may be correspondingly installed based on the stacking order of the horizontal solar panel 510 and the vertical solar panel 520. For example, when the first solar panel assembly 500 is in a storage state, if the horizontal solar panel 510 is stacked above the vertical solar panel 520, the first pulling tool 610 must first rotate the horizontal solar panel 510 and then the second pulling tool 620 must rotate the vertical solar panel 520 in the process of the cover 200 opening the storage space. Therefore, the first pulling tool 610 is connected to the cover 200 and the housing 100 and is connected to the housing 100. As the cover body 200 moves away from the center of the body 100, the second traction device 620 is connected to the middle part of the opening and closing device 300 and the housing 100, and approaches the center of the housing 100. In the initial stage of the cover body 200 moving away from the housing 100, only the first traction device 610 is gradually tightened, and as the cover body 200 continues to move away from the housing 100, the second traction device 620 is gradually tightened, thereby first rotating the horizontal solar panel 510 and then rotating the vertical solar panel 520, thereby avoiding interference or collision during the semi-expansion of the horizontal solar panel 510 and the semi-expansion of the vertical solar panel 520, and improving the opening of the storage space and the smooth deployment of the first solar panel assembly 500.

[0035] In one embodiment, the switching device 300 includes: a scissors assembly 310 including two support arms 311, the two support arms 311 being crossed at their middle portions and rotatably connected, and the two support arms 311 being both slidably connected at their tips to the lid body 200; a drive assembly for drivingly connecting the bottom ends of the two support arms 311; Here, the drive assembly drives the bottom ends of the two support arms 311 to move towards each other, thereby causing the lid body 200 to move away from the housing 100 and open the storage space, or the drive assembly drives the bottom ends of the two support arms 311 to move away from each other, thereby causing the lid body 200 to engage with the housing 100 and close the storage space.

[0036] 4 and 9, in an embodiment of the present invention, the opening and closing device 300 includes a scissors assembly 310 and a drive assembly, and the drive assembly drives two support arms 311 of the scissors assembly 310 to change the cross angle, thereby lowering the cover body 200 to engage with the housing 100 to close the storage space, or lifting the cover body 200 to separate it from the housing 100 to open the storage space. The scissors assembly 310 drives the cover 200 to move closer to or away from the housing 100 by vertically raising and lowering it, which has a simple structure and makes it easy to process and assemble the scissors assembly 310; on the other hand, the tips of the two support arms 311 each form a connection point with the cover 200, and the two connection points make it easy for the cover 200 to maintain a stable posture when it is stationary or moving, which helps to improve the positioning accuracy and repeatable positioning accuracy of the cover 200, ensures that the accommodating space is tightly closed when the cover 200 is engaged with the housing 100, and further improves the protective effect of the housing 100 and the cover 200 on the components inside the accommodating space; on the other hand, the scissors assembly 310 and the driving assembly are installed within the accommodating space, so that the housing 100 and the cover 200 can provide a protective effect for the opening and closing device 300 and extend the service life of the opening and closing device 300.

[0037] In one embodiment, the drive assembly comprises: A lead screw having a first thread on an outer peripheral wall at one end of the lead screw and a second thread on an outer peripheral wall at the other end of the lead screw, the first thread and the second thread rotating in opposite directions; Two nut structures are provided, each of which is fitted to the outside of the lead screw, one nut structure is connected to the first screw, and the other nut structure is connected to the second screw, and one nut structure is rotatably connected to the bottom end of each support arm 311; and a motor drivingly connected to the lead screw for driving rotation of the lead screw to move the two nut structures toward or away from each other.

[0038] In an embodiment of the present invention, the drive assembly includes a motor, a lead screw and two nut structures, where the lead screw and the two nut structures respectively form a screw-nut mechanism. Since the rotation directions of the first screw and the second screw are opposite, when the lead screw rotates, the two nut structures move toward or away from each other along the axial direction of the lead screw, thereby causing the bottom ends of the two support arms 311 to move toward or away from each other, and further changing the crossing angle of the two support arms 311, thereby allowing the cover body 200 to open and close the storage space. The drive assembly drives the scissors assembly 310 in the form of a screw-nut mechanism, which has high movement precision and improves the accuracy and stability of the movement of the lid body 200, thereby ensuring precision when the lid body 200 is engaged with the housing 100 and ensuring the protective effect of the lid body 200 and the housing 100 against the components inside the storage space. In addition, the movement of the two support arms 311 is realized by one motor and one lead screw, which not only simplifies the number of components and reduces manufacturing costs, but also improves the synchronization of the movement of the two support arms 311 and reduces the possibility of the lid body 200 being distorted due to asynchronous movement of the two support arms 311.

[0039] Specifically, in this embodiment, referring to FIG. 8, a first slide rail is provided on the housing 100, a first slide groove is provided on the first slide rail, a lead screw is provided in the first slide groove, and the bottom ends of the two support arms 311 both enter the first slide groove and move along the first slide groove. Referring to FIG. 10, a second slide rail is provided on the cover 200, a second slide groove is provided on the second slide rail, and the tips of the two support arms 311 both enter the second slide groove and move along the second slide groove. By providing the first slide groove and the second slide groove, the movement direction of the two support arms 311 is guided, thereby reducing the possibility of the movement deviation of the two support arms 311, thereby reducing the possibility of the opening and closing device 300 being stuck, and improving the smoothness of opening and closing the cover 200.

[0040] In one embodiment, the opening and closing device 300 further includes two elastic members 320, which are symmetrically arranged on both sides of the center line of the cover body 200, and each elastic member 320 is elastically connected to the middle portion of the cover body 200 and one support arm 311.

[0041] 10-11, in the embodiment of the present invention, the opening and closing device 300 further includes two elastic members 320, which are symmetrically installed on both sides of the center line of the cover body 200, and the center line is perpendicular to the plane where the two support arms 311 intersect, and the axes of each elastic member 320 are both parallel to the plane where the two support arms 311 intersect. When the two support arms 311 change their intersecting angle, each elastic member 320 is elastically connected to the middle part of the cover body 200 and one of the support arms 311, so that the two elastic members 320 are elastically connected to the middle part of the cover body 200 and one of the support arms 311.
