Description

Technical Field

[0001] The present invention relates to an automobile photovoltaic power generation device, and more particularly to an automobile photovoltaic power generation roof box with environmental induction linkage and forced retraction. Background Art

[0002] Photovoltaic power generation technology is a technology that converts light energy into electrical energy. Based on the advantages of clean and pollution-free energy and convenience in obtaining energy, its application scenarios are very extensive. Traditional photovoltaic and optoelectronic technologies are mainly applied to fixed buildings, such as being fixedly installed on the top floor or roof of buildings as a power system. With the rapid development of new energy vehicles in China, the charging problem has become the primary problem to be solved for new energy vehicles. For example, the popularization of charging piles in many cities is small and the mobility is poor. Therefore, there is an urgent need to provide a foldable photovoltaic expansion device based on photovoltaic power generation technology so that car owners can carry it with them and use it when going out.

[0003] However, there are still many problems with the foldable photovoltaic expansion devices currently on the market that have not been perfected. They cannot forcibly and automatically retract the sailboards in various scenarios, resulting in structural collision damage. For example, when parking and suddenly encountering heavy rain, the sailboards cannot be forcibly and automatically retracted according to rain induction, resulting in short circuits caused by the photovoltaic power generation device coming into contact with water; for example, during the slow driving of the vehicle, vibration signals cannot be detected, resulting in the vibrating and colliding of the deployed sailboards, causing component deformation and damage, affecting its lifespan; for another example, during the slow driving or parking of the vehicle, wind speed cannot be detected, resulting in the deployed sailboards being blown by strong winds and colliding with each other, causing component deformation and damage, affecting its lifespan. In summary, the existing foldable photovoltaic expansion devices cannot automatically adjust the state of the photovoltaic panels according to environmental changes, reducing the stability and reliability of photovoltaic power generation.

[0021] Preferably, the environmental induction system is linked and controlled with the telescopic brake controller, and four scenarios for the forced retraction state of the photovoltaic panels installed on the car's photovoltaic power generation roof box are realized through an optical rain sensor, a vibration sensor, and an electric rotating anemometer.

[0022] Furthermore, the trigger condition for forced retraction by rain sensing through an optical rain sensor is that the optical rain sensor detects continuous rainfall, including the following steps:

[0023] A1. After the environmental sensing system detects continuous rainfall through the optical rain sensor, it sends a rain amount over-limit signal to the telescopic braking controller;

[0024] A2. The telescopic braking controller starts the forced retraction program. Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the retraction of the lower roof box sub-frame, the upper roof box sub-frame is retracted simultaneously in the same steps. The specific steps are as follows:

[0025] A21. Start the third drive motor to rotate counterclockwise, so that the upper winch of the third double-layer winch winds up the steel cable for pulling and retracting the sub-frame photovoltaic panel. The steel cable for pulling and retracting the sub-frame photovoltaic panel pulls the first sub-frame sheet metal part and the second sub-frame sheet metal part, so that the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame slide into the roof box sub-frame body along the first sub-frame side extension guide rail and the second sub-frame side extension guide rail. The male head on the side of the first sub-frame photovoltaic panel is separated from the female seat on the side of the first sub-frame photovoltaic panel, and the male head on the side of the second sub-frame photovoltaic panel is separated from the female seat on the side of the second sub-frame photovoltaic panel;

[0026] A22. After completing the specific step A21, start the second adjustment servo motor to rotate counterclockwise, so that the upper winch of the second double-layer winch winds up the telescopic steel cable of the sub-frame photovoltaic panel side extension frame. The telescopic steel cable of the sub-frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, so that the sub-frame sliding strip slides along the sub-frame sliding guide rail, driving the roof box sub-frame body to slide into the roof box main frame. At this time, the male connector with double holes on the lower sub-frame is separated from the female connector with double holes on the lower sub-frame;

[0027] A23. After completing the specific step A22, start the first drive motor to rotate counterclockwise, so that the upper winch of the first double-layer winch winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame. The first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail. At this time, the male head on the side of the first main frame photovoltaic panel is separated from the female seat on the side of the first main frame photovoltaic panel, and the male head on the side of the second main frame photovoltaic panel is separated from the female seat on the side of the second main frame photovoltaic panel;

[0028] A3. After complete retraction, the system enters the standby state.

[0029] Furthermore, forced retraction by vibration sensing is achieved by detecting abnormal vibrations during driving through a vibration sensor. The trigger condition is that the vehicle speed > 30 km / h, including the following steps:

[0030] B1. When the environmental sensing system detects a severe vibration through the vibration sensor under the condition that the vehicle speed > 30 km / h, it sends a signal of "start recovery due to vibration exceeding the limit" to the telescopic braking controller;

[0031] B2. The telescopic braking controller starts the forced recovery program. Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the recovery of the lower roof box sub-frame, the upper roof box sub-frame is recovered simultaneously in the same steps. The specific steps are as follows:

[0032] B21. Start the third drive motor to rotate counterclockwise at 50% of the rated speed, so that the upper winch of the third double-layer winch slowly winds up the steel cable for pulling and retracting the sub-frame photovoltaic panel. The steel cable for pulling and retracting the sub-frame photovoltaic panel pulls the first sub-frame sheet metal part and the second sub-frame sheet metal part, so that the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame slide into the roof box sub-frame body along the first sub-frame side extension guide rail and the second sub-frame side extension guide rail. The male head on the side of the first sub-frame photovoltaic panel is separated from the female seat on the side of the first sub-frame photovoltaic panel, and the male head on the side of the second sub-frame photovoltaic panel is separated from the female seat on the side of the second sub-frame photovoltaic panel;

[0033] B22. After completing the specific step B21, start the second adjustment servo motor to rotate counterclockwise at 50% of the rated speed, so that the upper winch of the second double-layer winch slowly winds up the telescopic steel cable of the sub-frame photovoltaic panel side extension frame. The telescopic steel cable of the sub-frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, so that the sub-frame sliding strip slides along the sub-frame sliding guide rail, driving the roof box sub-frame body to slide into the roof box main frame. At this time, the double-hole power-on male connector of the lower sub-frame is separated from the double-hole power-on female socket of the lower sub-frame;

[0034] B23. After completing the specific step B22, start the first drive motor to rotate counterclockwise at 50% of the rated speed, so that the upper winch of the first double-layer winch slowly winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame. The first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail. At this time, the male head on the side of the first main frame photovoltaic panel is separated from the female seat on the side of the first main frame photovoltaic panel, and the male head on the side of the second main frame photovoltaic panel is separated from the female seat on the side of the second main frame photovoltaic panel;

[0035] B3. After complete recovery, the system enters the standby state.

[0036] Furthermore, the wind speed induction forced recovery is realized by detecting the wind speed during driving through an electric rotation anemometer. The triggering condition is that the wind speed > 30 km / h and the vehicle speed > 30 km / h, including the following steps:

[0037] C1. When the vehicle speed > 30 km / h, after the environmental sensing system detects that the wind speed > 30 km / h through the electric rotation anemometer, it sends a signal of "wind speed over-limit starts recovery" to the telescopic braking controller;

[0038] C2. The telescopic braking controller starts the forced retraction program. Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the retraction of the lower roof box sub-frame, the upper roof box sub-frame is retracted simultaneously in the same steps. The specific steps are as follows:

[0039] C21. Start the third drive motor to rotate counterclockwise, so that the upper winch of the third double-layer winch winds up the steel cable for pulling and retracting the sub-frame photovoltaic panel, and the steel cable for pulling and retracting the sub-frame photovoltaic panel pulls the first sub-frame sheet metal part and the second sub-frame sheet metal part through the steel cable for pulling and retracting the sub-frame photovoltaic panel, thereby making the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame slide into the roof box sub-frame body along the first sub-frame side extension guide rail and the second sub-frame side extension guide rail, and the male head on the side of the first sub-frame photovoltaic panel is separated from the female seat on the side of the first sub-frame photovoltaic panel, and the male head on the side of the second sub-frame photovoltaic panel is separated from the female seat on the side of the second sub-frame photovoltaic panel;

[0040] C22. After completing the specific step C21, start the second adjustment servo motor to rotate counterclockwise, so that the upper winch of the second double-layer winch winds up the telescopic steel cable of the sub-frame photovoltaic panel side extension frame. The telescopic steel cable of the sub-frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, so that the sub-frame sliding strip slides along the sub-frame sliding guide rail, driving the roof box sub-frame body to slide into the roof box main frame. At this time, the male connector with double holes on the lower sub-frame is separated from the female connector with double holes on the lower sub-frame;

[0041] C23. After completing the specific step C22, start the first drive motor to rotate counterclockwise, so that the upper winch of the first double-layer winch winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame, and the first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail. At this time, the male head on the side of the first main frame photovoltaic panel is separated from the female seat on the side of the first main frame photovoltaic panel, and the male head on the side of the second main frame photovoltaic panel is separated from the female seat on the side of the second main frame photovoltaic panel;

[0042] C3. After complete retraction, the system enters the standby state.

[0043] Furthermore, during the parking process, the wind speed induction forced retraction is realized through the electric rotation anemometer. The triggering condition is that the wind speed > 30 km / h, including the following steps:

[0044] D1. After the environmental sensing system detects that the wind speed > 30 km / h through the electric rotation anemometer, it sends a signal of "wind speed over-limit starts recovery" to the telescopic braking controller;

[0045] D2. The telescopic brake controller starts the forced retraction program. Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the retraction of the lower roof box sub-frame, the upper roof box sub-frame is retracted simultaneously in the same steps. The specific steps are as follows:

[0046] D21. Start the third drive motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the third double-layer winch slowly winds up the steel cable for pulling and retracting the sub-frame photovoltaic panel. The steel cable for pulling and retracting the sub-frame photovoltaic panel pulls the first sub-frame sheet metal part and the second sub-frame sheet metal part, so that the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame slide into the roof box sub-frame body along the first sub-frame side extension guide rail and the second sub-frame side extension guide rail. The male head on the side of the first sub-frame photovoltaic panel is separated from the female seat on the side of the first sub-frame photovoltaic panel, and the male head on the side of the second sub-frame photovoltaic panel is separated from the female seat on the side of the second sub-frame photovoltaic panel;

[0047] D22. After completing the specific step D21, start the second adjustment servo motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the second double-layer winch slowly winds up the telescopic steel cable of the sub-frame photovoltaic panel side extension frame. The telescopic steel cable of the sub-frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, so that the sub-frame sliding strip slides along the sub-frame sliding guide rail, driving the roof box sub-frame body to slide into the roof box main frame. At this time, the double-hole power-on male connector on the lower sub-frame is separated from the double-hole power-on female socket on the lower sub-frame;

[0048] D23. After completing the specific step B22, start the first drive motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the first double-layer winch slowly winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame. The first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail.

Specifically, both sides of the second auxiliary frame center rod 267 are bent downward at the lower end, which can cooperate with the auxiliary frame auxiliary T-shaped steel bar 244. During actual operation, the second auxiliary frame center rod 267 uses the auxiliary frame auxiliary T-shaped steel bar 244 for guiding and sliding, and the cooperation between the second auxiliary frame center rod 267 and the auxiliary frame auxiliary T-shaped steel bar 244 enhances the structural strength of the second auxiliary frame photovoltaic panel side extension frame 26, preventing the second auxiliary frame photovoltaic panel side extension frame 26 from sagging and deforming due to lack of support at the middle part after extension;

[0082] The third drive assembly 27 includes a third double-layer winch 271 fixedly installed on the auxiliary frame body 22 of the roof box by bolts, a third drive motor 272 fixedly installed on the auxiliary frame body 22 of the roof box by bolts and having an output end connected to the third double-layer winch 271, and an auxiliary frame photovoltaic panel deployment and retraction steel wire rope 273 with both ends fixedly connected to the third double-layer winch 271 and arranged on the auxiliary frame body 22 of the roof box; the auxiliary frame photovoltaic panel deployment and retraction steel wire rope 273 includes a fifth auxiliary frame steel wire rope turning wheel 274a and a sixth auxiliary frame steel wire rope turning wheel 274b installed on both sides of one end of the auxiliary frame body 22 of the roof box for pulling the first auxiliary frame photovoltaic panel side extension frame 25 to perform telescopic activities, and a seventh auxiliary frame steel wire rope turning wheel 274c and an eighth auxiliary frame steel wire rope turning wheel 274d installed on both sides of the other end of the first auxiliary frame photovoltaic panel side extension frame 25 for pulling the second auxiliary frame photovoltaic panel side extension frame 26. Specifically, the auxiliary frame photovoltaic panel deployment and retraction steel wire rope 273 sequentially passes through the first auxiliary frame sheet metal part 254 with a steel wire rope clamp block and the second auxiliary frame sheet metal part 264 with a steel wire rope clamp block, and is fixed by screwing in screws in cooperation with the steel wire rope clamp block, so that the auxiliary frame photovoltaic panel deployment and retraction steel wire rope 273 pulls the first auxiliary frame photovoltaic panel side extension frame 25 and the second auxiliary frame photovoltaic panel side extension frame 26 to slide out of the auxiliary frame body 22 of the roof box or slide into the auxiliary frame body 22 of the roof box simultaneously through the first auxiliary frame sheet metal part 254 with a steel wire rope clamp block and the second auxiliary frame sheet metal part 264 with a steel wire rope clamp block.

[0083] It should be further noted that the lower-layer sub-frame double-hole energized 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 wires, and the second adjustment servo motor 232 is connected to the telescopic brake controller 5 through a wire.

[0084] Specifically, the telescopic movement process of the lower-layer roof box sub-frame 2 is as follows:

[0085] When the lower-layer roof box sub-frame 2 is extended, the specific method is as follows: The second adjustment servo motor 232 drives the second double-layer winch 231 to rotate clockwise, drives the second adjustment servo motor 232 to rotate, uses the upper winch of the second double-layer winch 231 to release the telescopic steel cable 233 of the sub-frame photovoltaic panel side extension frame, and the lower winch of the second double-layer winch 231 winds up the telescopic steel cable 233 of the sub-frame photovoltaic panel side extension frame. During this process, the telescopic steel cable 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 cable fixing block 225, and makes the lower-layer sub-frame double-hole energized male connector 224 dock with the lower-layer sub-frame double-hole energized female socket 111 on the front side of the roof box main frame body 11, so that the lower-layer roof box sub-frame 2 is connected to the battery assembly 4, and at the same time provides power for the start of the third drive motor 272. Driven by the third drive motor 272 clockwise, drives the third drive motor 272 to rotate, uses the upper winch of the third double-layer winch 271 to release the pulling and retracting steel cable 273 for the expansion of the sub-frame photovoltaic panel, and the lower winch of the third double-layer winch 271 winds up the pulling and retracting steel cable 273 for the expansion of the sub-frame photovoltaic panel. During this process, the pulling and retracting steel cable 273 for the expansion of the sub-frame photovoltaic panel simultaneously pulls the first sub-frame sheet metal part 254 with a steel cable clamp block and the second sub-frame sheet metal part 264 with a steel cable 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 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 socket 252 and the second sub-frame photovoltaic panel side male head 26 to dock with the second sub-frame photovoltaic panel side female socket 262. At this time, the expanded first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 transmit the electric energy generated by the solar invention to the battery assembly 4 for storage;

[0086] When the lower-layer roof box sub-frame 2 retracts, the telescopic brake controller 5 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 retract first, and then controls the lower-layer roof box sub-frame 2 to slide into the roof box main frame body 11. The specific method is as follows: The third drive motor 272 rotates counterclockwise to drive the third drive motor 272 to rotate. The upper winch of the third double-layer winch 271 winds the sub-frame photovoltaic panel deployment and retraction steel cable 273, while the lower winch of the third double-layer winch 271 releases the sub-frame photovoltaic panel deployment and retraction steel cable 273. During this process, the sub-frame photovoltaic panel deployment and retraction steel cable 273 simultaneously pulls the first sub-frame sheet metal part 254 with a steel cable clamp block and the second sub-frame sheet metal part 264 with a steel cable 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 into the roof box sub-frame body 22 simultaneously, and makes the first sub-frame photovoltaic panel side male connector 256 pull out from the first sub-frame photovoltaic panel side female seat 252, and the second sub-frame photovoltaic panel side male connector 26 pull out from the second sub-frame photovoltaic panel side female seat 262. At this time, 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 short-circuit situations. After the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 are retracted, the second adjustment servo motor 232 is started to drive the second double-layer winch 231 to rotate counterclockwise, driving the second adjustment servo motor 232 to rotate. The upper winch of the second double-layer winch 231 winds the sub-frame photovoltaic panel side extension frame telescopic steel cable 233, while the lower winch of the second double-layer winch 231 releases the sub-frame photovoltaic panel side extension frame telescopic steel cable 233. During this process, the sub-frame photovoltaic panel side extension frame telescopic steel cable 233 pulls the roof box sub-frame body 22 to slide into the roof box main frame body 11 through the steel cable fixing block 225, and makes the lower-layer sub-frame double-hole power-on male connector 224 pull out from the lower-layer sub-frame double-hole power-on female socket 111 on the front side of the roof box main frame body 11, so that the lower-layer roof box sub-frame 2 disconnects the charging connection and the power supply of the third drive assembly 27 to avoid short-circuit situations.

[0087] It should be further noted that the structure of the upper-layer roof box sub-frame 3 is the same as that of the lower-layer roof box sub-frame 2. In actual assembly, the sub-frame auxiliary support parts in the upper-layer roof box sub-frame 3 are welded according to their actual lengths. In this embodiment, since the upper-layer roof box sub-frame 3 is shorter in length, there is no need to weld the sub-frame auxiliary support parts.

[0088] As Figure 12As shown in the figure, the environmental sensing system 6 includes a waterproof PCB circuit board 61 embedded at the front end of the housing of the main frame 1 of the roof box and connected to the telescopic braking controller 5 through a wire, an optical rain sensor 62 and a vibration sensor 63 soldered on the surface of the waterproof PCB circuit board 61, an angle steel mounting seat 64 fixedly installed on one side of the front end of the main frame 1 of the roof box, and an electric rotation anemometer 65 connected to the waterproof PCB circuit board 61 through a wire and fixedly installed on the angle steel mounting seat 64.

[0089] It should be further noted that the environmental sensing system 6 is linked with the telescopic braking controller 5 to achieve the forced retraction state of the photovoltaic panels installed on the car's photovoltaic power generation roof box in four scenarios through the optical rain sensor 62, the vibration sensor 63 and the electric rotation anemometer 65.

[0090] Scenario 1: The trigger condition for rain-induced forced retraction through the optical rain sensor 62 is that the optical rain sensor 62 detects continuous rainfall, including the following steps:

[0091] A1. After the environmental sensing system 6 detects continuous rainfall through the optical rain sensor 62, it sends a rain volume over-limit signal to the telescopic braking controller 5;

[0092] A2. The telescopic braking controller 5 starts the forced retraction program. Since the structure of the upper roof box sub-frame 3 is the same as that of the lower roof box sub-frame 2, during the retraction of the lower roof box sub-frame 2, the upper roof box sub-frame 3 retracts simultaneously in the same steps. The specific steps are as follows:

[0093] A21. Start the third drive motor 272 to rotate counterclockwise, so that the upper winch of the third double-layer winch 271 winds up the steel rope 273 for pulling out the sub-frame photovoltaic panel. The first sub-frame sheet metal part 254 and the second sub-frame sheet metal part 264 are pulled by the steel rope 273 for pulling out the sub-frame photovoltaic panel, so that the first sub-frame photovoltaic panel side extension frame 25 and the second sub-frame photovoltaic panel side extension frame 26 slide into the roof box sub-frame body 22 along the first sub-frame side extension guide rail 251 and the second sub-frame side extension guide rail 261. The male head 256 on the side of the first sub-frame photovoltaic panel is separated from the female seat 252 on the side of the first sub-frame photovoltaic panel, and the male head 265 on the side of the second sub-frame photovoltaic panel is separated from the female seat 262 on the side of the second sub-frame photovoltaic panel;

[0094] After completing the specific step A21, start the second adjusting servo motor 232 to rotate counterclockwise, so that the upper winch of the second double-layer winch 231 winds up the telescopic steel cable 233 of the extension frame on the side of the sub-frame photovoltaic panel. The telescopic steel cable 233 of the extension frame on the side of the sub-frame photovoltaic panel pulls the L-shaped bracket 212 through the steel cable fixing block 225, so that the sliding strip 221 of the sub-frame slides along the sliding guide 21 of the sub-frame, driving the sub-frame body 22 of the roof box into the main frame 1 of the roof box. At this time, the double-hole power supply male connector 224 of the lower layer of the sub-frame is separated from the double-hole power supply female socket 111 of the lower layer of the sub-frame;

[0095] After completing the specific step A22, start the first driving motor 152 to rotate counterclockwise, so that the upper winch of the first double-layer winch 153 winds up the telescopic steel cable 154 of the extension frame on the side of the main-frame photovoltaic panel.

Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the recovery of the lower roof box sub-frame, the upper roof box sub-frame is recovered simultaneously in the same steps. The specific steps are as follows: C21. Start the third drive motor to rotate counterclockwise, so that the upper winch of the third double-layer winch winds up the steel cable for pulling and retracting the sub-frame photovoltaic panel. The steel cable for pulling and retracting the sub-frame photovoltaic panel pulls the first sub-frame sheet metal part and the second sub-frame sheet metal part, so that the first sub-frame photovoltaic panel side extension frame and the second sub-frame photovoltaic panel side extension frame slide into the roof box sub-frame body along the first sub-frame side extension guide rail and the second sub-frame side extension guide rail. The male head on the side of the first sub-frame photovoltaic panel is separated from the female seat on the side of the first sub-frame photovoltaic panel, and the male head on the side of the second sub-frame photovoltaic panel is separated from the female seat on the side of the second sub-frame photovoltaic panel; C22. After completing the specific step C21, start the second adjustment servo motor to rotate counterclockwise, so that the upper winch of the second double-layer winch winds up the telescopic steel cable of the sub-frame photovoltaic panel side extension frame. The telescopic steel cable of the sub-frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, so that the sub-frame sliding strip slides along the sub-frame sliding guide rail, driving the roof box sub-frame body to slide into the roof box main frame. At this time, the double-hole power-on male connector of the lower sub-frame is separated from the double-hole power-on female socket of the lower sub-frame; C23. After completing the specific step C22, start the first drive motor to rotate counterclockwise, so that the upper winch of the first double-layer winch winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame. The first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail. At this time, the male head on the side of the first main frame photovoltaic panel is separated from the female seat on the side of the first main frame photovoltaic panel, and the male head on the side of the second main frame photovoltaic panel is separated from the female seat on the side of the second main frame photovoltaic panel; C3. After complete retraction, the system enters the standby state.

9. The vehicle photovoltaic power generation roof box with environmental induction linkage forced retraction according to claim 6, characterized in that, During parking, the wind speed induction is forcibly retracted through an electric rotation wind speed tester. The trigger condition is wind speed > 30 km / h, and the steps are as follows: D1. After the environmental induction system detects that the wind speed > 30 km / h through the electric rotation wind speed tester, it sends a signal of "wind speed exceeding the limit to start recovery" to the telescopic braking controller; D2. The telescopic braking controller starts the forced recovery program. Since the structure of the upper roof box sub-frame is the same as that of the lower roof box sub-frame, during the recovery of the lower roof box sub-frame, the upper roof box sub-frame is recovered simultaneously in the same steps. The specific steps are as follows: D21. Start the third drive motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the third double-layer winch slowly winds up the steel cable for pulling and retracting the auxiliary frame photovoltaic panel, and the steel cable for pulling and retracting the auxiliary frame photovoltaic panel pulls the first auxiliary frame sheet metal part and the second auxiliary frame sheet metal part, thereby causing the first auxiliary frame photovoltaic panel side extension frame and the second auxiliary frame photovoltaic panel side extension frame to slide into the roof box auxiliary frame body along the first auxiliary frame side extension guide rail and the second auxiliary frame side extension guide rail, and the male connector on the side of the first auxiliary frame photovoltaic panel is disengaged from the female connector on the side of the first auxiliary frame photovoltaic panel, and the male connector on the side of the second auxiliary frame photovoltaic panel is disengaged from the female connector on the side of the second auxiliary frame photovoltaic panel; D22. After completing the specific step D21, start the second adjustment servo motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the second double-layer winch slowly winds up the telescopic steel cable of the auxiliary frame photovoltaic panel side extension frame. The telescopic steel cable of the auxiliary frame photovoltaic panel side extension frame pulls the L-shaped bracket through the steel cable fixing block, causing the auxiliary frame sliding strip to slide along the auxiliary frame sliding guide rail, driving the roof box auxiliary frame body to slide into the roof box main frame. At this time, the lower-layer auxiliary frame double-hole power-on male connector is disengaged from the lower-layer auxiliary frame double-hole power-on female socket; D23. After completing the specific step B22, start the first drive motor to rotate counterclockwise at 25% of the rated speed, so that the upper winch of the first double-layer winch slowly winds up the telescopic steel cable of the main frame photovoltaic panel side extension frame. The telescopic steel cable of the main frame photovoltaic panel side extension frame pulls the square frame and the L-shaped frame, and the first main frame photovoltaic panel side extension frame slides into the roof box main frame body along the first main frame side extension guide rail, and the second main frame photovoltaic panel side extension frame slides into the roof box main frame body along the second main frame side extension guide rail. At this time, the male connector on the side of the first main frame photovoltaic panel is disengaged from the female connector on the side of the first main frame photovoltaic panel, and the male connector on the side of the second main frame photovoltaic panel is disengaged from the female connector on the side of the second main frame photovoltaic panel; D3. After complete retraction, the system enters the standby state.
