Description

Technical Field

[0001] The invention relates to automobile photovoltaic power generation equipment, and in particular to a solar photovoltaic power generation roof box for a new energy automobile. Background Art

[0002] The bottleneck that prevents the rapid development of electric vehicles is that there are no charging piles everywhere in the city, and the charging time is very long, and electricity bills have to be paid. At present, solar energy technology is developing rapidly. There are amorphous silicon panels that have good power generation effects despite poor sunlight, and there are also flexible solar panels that have large power generation despite small size. More importantly, the effect of solar power generation is quite good in actual application. A kilowatt solar panel can generate more than 90% of electricity whenever the sunlight is good, which is amazing. It can actually produce 1 kilowatt of electricity. For example, how much height and water flow are needed for hydropower generation, and it does not need to output any energy. However, the main problem is that, for example, the roof area of ​​a small car is too small, and at most one kilowatt solar panel can be placed, which is far from enough to generate the electricity required for the high power of an electric car. The core is that the roof area is not large enough.

[0003] For example, a telescopic photovoltaic module bracket is announced in Chinese utility model CN208209857U. Although this type of photovoltaic module bracket can telescope and unfold at least two photovoltaic panels to increase the area of ​​sunlight exposure; specifically, this type of photovoltaic module bracket is used in conjunction with a fixed frame and a movable frame. The photovoltaic panels are installed on the fixed frame and the movable frame. The movable frame can be telescoped and unfolded or folded relative to the fixed frame to fold multiple photovoltaic panels together to complete the folding. However, although this type of photovoltaic module bracket can fully expand the area of ​​photovoltaic panel power generation, there are still many problems in the structure of the photovoltaic module bracket and the telescopic path of the photovoltaic module bracket. For example, Problem 1: Since the photovoltaic panel has a single telescopic method and the components are large and complex, that is, a driving mechanism is installed for the telescopic activity in each direction, such as belt pulling for telescopic activity and screw transmission for telescopic activity, most of the space of the inverted roof box is occupied by the belt and the motor or the screw and the motor, which also increases the weight of the roof box and is not conducive to high-speed driving of the vehicle; Problem 2: Due to the increase in the expansion area of ​​the photovoltaic panel, the photovoltaic module bracket does not have a structure to improve the structural stability, resulting in the central part of the photovoltaic panel being deformed due to long-term unsupported inversion after extension, thereby affecting the telescopic activity; Problem 3: No optimized management is performed for the storage and use of electricity, and it is impossible to ensure that the system can work efficiently and flexibly, thereby affecting the power generation efficiency. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] 1.

The main body or slides into the main body of the roof box, the photovoltaic panel of the sub-frame in the third drive assembly is unfolded and retracted by the steel rope through the first sub-frame sheet metal with a steel rope clamp and the second sub-frame sheet metal with a steel rope clamp to pull the photovoltaic panel side extension frame of the first sub-frame and the photovoltaic panel side extension frame of the second sub-frame to slide out of the roof box sub-frame body or slide into the roof box sub-frame body at the same time, which can ensure synchronous extension and retraction, avoiding structural deformation caused by unilateral jamming; the flexible transmission of the steel rope can buffer the vibration impact of the vehicle during driving and reduce mechanical wear. In addition, the steel rope system is enclosed inside the roof box, which reduces external pollution and has a low maintenance frequency;

[0025] 2. The structural design of the main frame auxiliary support member can enhance the structural stability of the first main frame photovoltaic panel side extension frame and the second main frame photovoltaic panel side extension frame, and can prevent the first main frame photovoltaic panel side extension frame and the second main frame photovoltaic panel side extension frame from sagging and deformation due to the lack of support in the middle after being extended, while the structural design of the sub-frame auxiliary support member can enhance the structural stability of the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame that slide out of the lower roof box sub-frame and the upper roof box sub-frame, and can prevent the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame from sagging and deformation due to the lack of support in the middle after being extended;

[0026] 3. The BMS battery management system in the battery assembly monitors the battery temperature in real time and actively dissipates heat through a liquid cooling cycle to ensure safety under high loads. The inverter provides bidirectional power supply to support the complementarity of energy storage and on-board batteries. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The third driving assembly 27 includes a third double-layer winch 271 fixedly mounted on the roof box sub-frame body 22 by bolts, a third driving motor 272 fixedly mounted on the roof box sub-frame body 22 by bolts and having its output end connected to the third double-layer winch 271, and a sub-frame photovoltaic panel deployment and retraction steel rope 273 arranged on the roof box sub-frame body 22, the two ends of which are respectively fixed to the third double-layer winch 271; the sub-frame photovoltaic panel deployment and retraction steel rope 273 includes a fifth sub-frame steel rope steering wheel 274a and a sixth sub-frame steel rope steering wheel 274b installed on both sides of one end of the roof box sub-frame body 2 for pulling the first sub-frame photovoltaic panel side extension frame 25 for telescopic activities, and a sixth sub-frame steel rope steering wheel 274b installed on the first sub-frame photovoltaic panel side extension frame 2 The seventh sub-frame steel rope steering wheel 274c and the eighth sub-frame steel rope steering wheel 274d on both sides of the other end are used to pull the second sub-frame photovoltaic panel side extension frame 26. Specifically, the sub-frame photovoltaic panel deployment and retraction steel rope 273 passes through the first sub-frame sheet metal 254 with steel rope clamp block and the second sub-frame sheet metal 264 with steel rope clamp block in sequence, and is fixed by screwing in screws and cooperating with the steel rope clamp block, so that the sub-frame photovoltaic panel deployment and retraction steel rope 273 passes through the first sub-frame sheet metal 254 with steel rope clamp block and the second sub-frame sheet metal 264 with steel rope clamp block to pull the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 to slide out of the roof box sub-frame body 22 or slide into the roof box sub-frame body 22 at the same time.

[0060] It should be further explained that the lower sub-frame double-hole powered male connector 224 is connected to the first sub-frame photovoltaic panel side female socket 252 in the first sub-frame photovoltaic panel side extension frame 25, the second sub-frame photovoltaic panel side female socket 262 in the second sub-frame photovoltaic panel side extension frame 26 and the third drive motor 272 in the third drive assembly 27 through electric wires, and the second drive motor 232 is connected to the telescopic brake controller 6 through a wire.

[0061] Specifically, the telescopic activity process of the lower roof box sub-frame 2 is as follows:

[0062] When the lower roof box sub-frame 2 is extended, the specific method is as follows: the second drive motor 232 drives the second double-layer winch 231 to move clockwise, drives the second drive motor 232 to rotate, and uses the upper winch of the second double-layer winch 231 to release the telescopic steel rope 233 of the sub-frame photovoltaic panel side extension frame, while the lower winch of the second double-layer winch 231 reels the telescopic steel rope 233 of the sub-frame photovoltaic panel side extension frame. In this process, the telescopic steel rope 233 of the sub-frame photovoltaic panel side extension frame pulls the roof box sub-frame body 22 out of the roof box main frame body 11 through the steel rope fixing block 225, and makes the lower sub-frame double-hole powered male connector 224 dock with the lower sub-frame double-hole powered female connector 111 on the front side of the roof box main frame body 11, so that the lower roof box sub-frame 2 is connected to the battery assembly 4, and at the same time provides power for the start-up of the third drive motor 272, and is driven clockwise by the third drive motor 272 to drive The third driving motor 272 is driven to rotate, and the upper winch of the third double-layer winch 271 is used to release the sub-frame photovoltaic panel unfolding and pulling steel rope 273, while the lower winch of the third double-layer winch 271 is used to reel in the sub-frame photovoltaic panel unfolding and pulling steel rope 273. In this process, the sub-frame photovoltaic panel unfolding and pulling steel rope 273 simultaneously pulls the first sub-frame sheet metal 254 with steel rope clamps and the second sub-frame sheet metal 264 with steel rope clamps to pull the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 to slide out of the roof box sub-frame body 22 at the same time, and drives the first sub-frame photovoltaic panel side male head 256 to dock with the first sub-frame photovoltaic panel side female seat 252, and the second sub-frame photovoltaic panel side male head 26 to dock with the second sub-frame photovoltaic panel side female seat 262. At this time, the unfolded first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 are transmitted to the battery assembly 4 for storage through the electric energy generated by the solar energy invention;

[0063] When the lower roof box sub-frame 2 is retracted, the telescopic brake controller 6 controls the third drive assembly 27 to drive the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 to be retracted first, and then the lower roof box sub-frame 2 is controlled to slide into the roof box main frame body 11. The specific method is: the third drive motor 272 is driven to rotate by the counterclockwise movement of the third drive motor 272, and the upper winch of the third double-layer winch 271 is used to reel in the photovoltaic panel of the sub-frame to unfold and retract the steel rope 273, and the third double-layer winch 2 The lower winch of 71 releases the sub-frame photovoltaic panel unfolding and pulling steel rope 273. During this process, the sub-frame photovoltaic panel unfolding and pulling steel rope 273 simultaneously pulls the first sub-frame sheet metal 254 with steel rope clamp and the second sub-frame sheet metal 264 with steel rope clamp to pull the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 to slide into the roof box sub-frame body 22 at the same time, and makes the first sub-frame photovoltaic panel side male connector 256 be pulled out from the first sub-frame photovoltaic panel side female connector 252, and the second sub-frame photovoltaic panel side male connector 26 be pulled out from the second sub-frame photovoltaic panel side female connector 254. The photovoltaic panel side mother seat 262 is pulled out, and the retracted first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 are disconnected from the battery assembly 4 to avoid a short circuit. After the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 are recovered, the second drive motor 232 is started to drive the second double-layer winch 231 to move counterclockwise, and the second drive motor 232 is driven to rotate, and the upper winch of the second double-layer winch 231 is used to reel in the telescopic steel rope 233 of the photovoltaic panel side extension frame of the sub-frame. The lower winch of the second double-layer winch 231 releases the telescopic steel rope 233 of the photovoltaic panel side extension frame of the sub-frame. During this process, the telescopic steel rope 233 of the photovoltaic panel side extension frame of the sub-frame pulls the roof box sub-frame body 22 through the steel rope fixing block 225 to slide into the roof box main frame body 11, and makes the lower sub-frame double-hole powered male connector 224 be pulled out from the lower sub-frame double-hole powered female connector 111 on the front end side of the roof box main frame body 11, so that the lower roof box sub-frame 2 disconnects the charging connection and the power supply of the third drive assembly 27 to avoid a short circuit.

[0064] It should be further explained that the structure of the upper roof box sub-frame 3 is the same as that of the lower roof box sub-frame 2. In actual assembly, the sub-frame auxiliary support members in the upper roof box sub-frame 3 are welded according to their actual length. In this embodiment, since the upper roof box sub-frame 3 is shorter, there is no need to weld the sub-frame auxiliary support members.

[0065] like Figure 12-13As shown, the battery assembly 4 includes a battery pack 41, a BMS battery management system 42 connected to the battery pack 41, a battery PLC control panel 43 connected to the BMS battery management system 42, a relay 44 connected to the battery PLC control panel 43, an inverter 45 connected to the BMS battery management system 42 at one end and to the vehicle battery at the other end, a cooling control system 46 connected to the battery PLC control panel 43 and having a liquid storage tank installed therein, a front iron box 47 for installing the BMS battery management system 42, the battery PLC control panel 43 and the relay 44, and a rear iron box 48 for installing the inverter 45 and the cooling control system 46.

[0066] The battery pack 41 includes a lower battery panel 411 formed by stacking blade batteries, an upper battery panel 412 formed by stacking blade batteries, a heat dissipation coil 413 located between the lower battery panel 411 and the upper battery panel 412, a limiting angle steel 414 for facilitating the stacking and fixing of the lower battery panel 411 and the upper battery panel 412, a lower battery temperature probe 415 installed on the side of the lower battery panel 411, an upper battery temperature probe 416 installed on the side of the upper battery panel 412, and a circulating pump 417 with one end connected to the heat dissipation coil 413 through a hose and the other end connected to the cooling control system 46 through a hose.

[0067] Specifically, the lower battery temperature probe 415, the lower battery temperature probe 415 and the circulation pump 417 are all connected to the battery PLC control panel 43, and the temperature change of the lower battery panel 411 and the upper battery panel 412 during use is timely detected by the lower battery temperature probe 415 and the lower battery temperature probe 415, that is, when high temperature occurs during power storage operation or power transmission to the vehicle battery through the inverter 45, the cooling control system 46 and the circulation pump 417 can be started in time to transport the cooling medium to the heat dissipation coil 413 for heat exchange and cooling.

[0068] It should be further explained that the liquid stored in the liquid storage tank inside the cooling control system 46 is one of water, ethylene glycol antifreeze, propylene glycol type coolant or alcohol type coolant.

[0069] In this embodiment, the wind speed sensor 5 is connected to the telescopic brake controller 6. When the solar photovoltaic power generation roof box is extended to perform photovoltaic power generation, the wind speed in the natural environment can be detected in real time. When the wind speed sensor 5 detects that the wind speed exceeds level 4, that is, the wind speed range is greater than 8m / s, a signal is sent to the telescopic brake controller 6 to force the retraction of the lower roof box sub-frame 2 and the upper roof box sub-frame 3 to prevent strong winds from damaging the solar photovoltaic panels.

[0070] In this embodiment, after the entire solar photovoltaic power generation roof box is fully extended, nine photovoltaic panels can be installed. Figure 2 shown.

[0071] The order of complete extension of the entire solar photovoltaic power generation roof box is: first, the first main frame photovoltaic panel side extension frame 13 and the second main frame photovoltaic panel side extension frame 14 are extended at the same time, and then the lower roof box sub-frame 2 and the upper roof box sub-frame 3 are extended at the same time, and finally, the first main frame photovoltaic panel side extension frame and the second main frame photovoltaic panel side extension frame in the lower roof box sub-frame 2 and the upper roof box sub-frame 3 are extended at the same time.
