Description

Technical Field

[0001] The present invention relates to automobile photovoltaic power generation equipment, and in particular to a photovoltaic panel stable telescopic structure applied to a roof box and an installation and telescopic method thereof. Background Art

[0002] With the rapid development of new energy vehicles in my country, charging has become the primary issue to be solved for new energy vehicles. For example, the number of charging piles installed 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 open it for use when going out.

[0003] Chinese utility model CN202323171115.0 announces a photovoltaic panel telescopic structure, which uses a steel wire rope and a pulley assembly as a transmission assembly. The steel wire rope is retracted and extended by a driver, so that the sliding part slides with the steel wire rope, and then drives the sub-frame to expand horizontally or retract and reset, thereby solving the problem that the center of gravity of the sub-frame is centered when belt drive is used in traditional designs, but there is left-right imbalance and shaking. Secondly, compared with the structure on the market that uses cylinder parts as the drive, the steel wire rope structure has the advantages of weight reduction, lightweight and low cost. According to the description and the drawings in the description, technical personnel in this field believe that a single winding drum bidirectional winding structure is used to control the retraction and extension of the two steel wire ropes 30 by the forward and reverse winding of the winding drum 37. Two steel ropes are wound on the winding drum in opposite directions, driving sliders 35 and 36 to move in opposite directions, relying on the pulley group to form a rectangular path, and mechanical synchronization depends on the winding accuracy. However, there is no dynamic angle adjustment function for the steel ropes. When the steel ropes drive sliders 35 and 36 to move, the steel ropes are prone to wear due to long-term mechanical operation, shortening their service life. At the same time, there is no dynamic angle adjustment function for the steel ropes, and it is impossible to ensure that the photovoltaic panels can work stably during the extension and contraction process, resulting in stiffness or asymmetric movement of other components, which gradually affects the functionality and reliability of the entire photovoltaic panel telescopic structure.

[0013] Furthermore, the installation and telescoping method of the photovoltaic panel stable telescopic structure applied to the roof box includes the following steps:

[0014] S1. The installation of the photovoltaic panel expansion and retraction steel rope:

[0015] S11. One end of the photovoltaic panel unfolding and pulling rope is released from the lower winch of the double-layer winch, and then passes through the lower guide rope wheel of the first steel rope guide wheel group to be turned, and is pressed and guided by the rope guide wheel. After being led out from the rope guide wheel, it passes through the first fixed wire block, and is turned through the lower steering wheel of the double-layer steering wheel, so that the photovoltaic panel unfolding and pulling rope is directly tilted and led to the second steel rope guide wheel group, and is turned through the second lower guide rope wheel of the second steel rope guide wheel group, and is then pressed and guided by the second rope guide wheel, so that the photovoltaic panel unfolding and pulling rope passes through the movable wire block. At this time, the photovoltaic panel unfolding and pulling rope is tilted and inserted into the single-layer steering wheel, and then from the single-layer The steering wheel turns and inserts into the second upper guide rope wheel of the second steel rope guide wheel group. When the photovoltaic panel unfolding and pulling steel rope passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope first inserts into the third fixed wire block at the lower end of the fourth sheet metal part in the second photovoltaic panel side extension frame on this side, and then turns through the second upper guide rope wheel of the second steel rope guide wheel group to insert into the upper steering wheel of the double-layer steering wheel for steering. When the photovoltaic panel unfolding and pulling steel rope passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope first inserts into the second fixed wire block at the lower end of the third sheet metal part in the second photovoltaic panel side extension frame on this side, and then turns through the first upper guide rope wheel of the first steel rope guide wheel group, and finally is fixed to the upper winch of the double-layer winch;

[0016] S12. After ensuring that the photovoltaic panel deployment and retraction wires are correctly inserted and installed, tighten the compression bolts into the first fixed conductor block, the movable conductor block, the second fixed conductor block, and the third fixed conductor block, respectively, so that the photovoltaic panel deployment and retraction wires are fixed to the first fixed conductor block, the movable conductor block, the second fixed conductor block, and the third fixed conductor block. This facilitates the photovoltaic panel deployment and retraction wires to pull the first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame through the first fixed conductor block, the movable conductor block, the second fixed conductor block, and the third fixed conductor block for retraction and extension.

[0017] S2. After completing the interlaced assembly of the photovoltaic panel deployment and retraction steel ropes in step S1, the specific extension activity process of the photovoltaic panel stable telescopic structure is: the driving motor is driven clockwise to drive the driving motor to rotate, and the upper winch of the double-layer winch is used to release the photovoltaic panel deployment and retraction steel rope, while the lower winch of the double-layer winch is wound up to retract the photovoltaic panel deployment and retraction steel rope, so that the photovoltaic panel deployment and retraction steel rope simultaneously pulls the first fixed wire block, the movable wire block, the second fixed wire block and the third fixed wire block, and waits until the first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame slide out of the roof stably at the same time. The box frame body, at this time, the first sheet metal male head is connected to the first photovoltaic panel female seat on one of the first side extension guide rails, the second sheet metal male head is connected to the first photovoltaic panel female seat on the other first side extension guide rail, the third sheet metal male head is connected to the second photovoltaic panel side female seat on one of the second side extension guide rails, and the fourth sheet metal male head is connected to the second photovoltaic panel side female seat on one of the second side extension guide rails, so that the photovoltaic panels installed in the unfolded first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame are connected to the battery for storage through the solar invention;

[0018] S3. The specific process of the photovoltaic panel stable telescopic structure contracting after stretching is: the double-layer winch is driven to rotate by driving the motor counterclockwise, and the upper winch of the double-layer winch is used to reel in the photovoltaic panel unfolding and pulling steel rope, while the lower winch of the double-layer winch releases the photovoltaic panel unfolding and pulling steel rope, so that the photovoltaic panel unfolding and pulling steel rope simultaneously pulls the first fixed wire block, the movable wire block, the second fixed wire block and the third fixed wire block. At this time, the first sheet metal male head and the second sheet metal male head are also pulled out from the first photovoltaic panel female seat on the two first side extension guide rails, and the third sheet metal male head and the fourth sheet metal male head are pulled out from the second photovoltaic panel side female seat on the two second side extension guide rails, so that the retracted first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame are disconnected from the battery to avoid short circuit.

[0019] Furthermore, in step S2, since the movable conductor block is installed on the photovoltaic panel deployment and retraction steel rope, it is obliquely inserted from the second pressure rope guide wheel to the single-layer steering wheel stroke end. In this process, the photovoltaic panel deployment and retraction steel rope pulls the movable conductor block to drive the second sheet metal to move toward the second pressure rope guide wheel. The movable conductor block is gradually rotated downward and adjusted through the hinge under the pulling of the photovoltaic panel deployment and retraction steel rope until the first photovoltaic panel side extension frame is stably extended. At this time, the movable conductor block is rotated downward and adjusted to the lowest angle through the hinge of the photovoltaic panel deployment and retraction steel rope.

[0020] Furthermore, in step S3, since the movable conductor block is installed on the photovoltaic panel deployment and pulling steel rope, it is obliquely inserted from the second pressure rope guide wheel to the single-layer steering wheel stroke end. In this process, the photovoltaic panel deployment and pulling steel rope pulls the movable conductor block to drive the second sheet metal to move toward the single-layer steering wheel. The movable conductor block is gradually rotated upward and adjusted through the hinge under the pulling of the photovoltaic panel deployment and pulling steel rope until the first photovoltaic panel side extension frame is stably retracted. At this time, the movable conductor block is rotated upward and adjusted to the maximum angle through the hinge photovoltaic panel deployment and pulling steel rope.

[0021] Beneficial effects of the present invention:

[0022] 1. The drive assembly uses photovoltaic panel deployment and retraction steel ropes in conjunction with the first steel rope guide pulley assembly, double-layer steering wheel, second steel rope guide pulley assembly and single-layer steering wheel to form a force closed loop. The hinges are then used to provide flexible dynamic angle adjustment to ensure the stable extension and retraction of the first photovoltaic panel side extension frame, reduce component wear, and improve the smoothness of the photovoltaic panel's stable extension and retraction through stable and smooth operation.

[0023] 2. The first photovoltaic panel side extension frame is suspended by the auxiliary rod itself, and one end of the auxiliary long support leg of the auxiliary frame welded to the auxiliary rod is directed toward the second photovoltaic panel side extension frame, and the second photovoltaic panel side extension frame is supported by the auxiliary T-shaped steel bar to prevent the first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame from sagging and deforming after being extended due to lack of support in the middle part. Therefore, the auxiliary support effectively prevents the instability of the first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame during the extension and retraction process, ensuring that the first photovoltaic panel side extension frame and the second photovoltaic panel side extension frame will not bend or damaged unnecessarily even when extended or retracted.

[0042] The present invention also provides a method for installing and retracting a photovoltaic panel stable retractable structure applied to a roof box, comprising the following steps:

[0043] S1. The photovoltaic panel is unfolded and the steel rope 54 is inserted and assembled:

[0044] S11. One end of the photovoltaic panel unfolding and pulling rope 54 is released from the lower winch of the double-layer winch 52, and then passes through the lower guide rope wheel of the first steel rope guide wheel group 55 for steering, and is guided by the rope pressure guide wheel. After being led out from the rope pressure guide wheel, it passes through the first fixed wire block 310, passes through the first fixed wire block 310, and is steered by the lower steering wheel of the double-layer steering wheel 56, so that the photovoltaic panel unfolding and pulling rope 54 is directly tilted and led to the second steel rope guide wheel group 57, and is steered by the second lower guide rope wheel 572 of the second steel rope guide wheel group 57, and is then guided by the second rope pressure guide wheel 573, so that the photovoltaic panel unfolding and pulling rope 54 passes through the movable wire block 313. At this time, the photovoltaic panel unfolding and pulling rope 54 is tilted and inserted into the single-layer steering wheel 58, and then is pulled out from the single-layer steering wheel 5 8 turns and inserts into the second upper guide rope wheel 574 of the second steel rope guide wheel group 57. When the photovoltaic panel unfolding and pulling steel rope 54 passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope 54 first passes through the third fixed wire block 411 at the lower end of the fourth sheet metal part 409 in the second photovoltaic panel side extension frame 4 on this side, and then passes through the second upper guide rope wheel 574 of the second steel rope guide wheel group 57 to turn and insert into the upper steering wheel of the double-layer steering wheel 56 for steering. When the photovoltaic panel unfolding and pulling steel rope 54 passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope 54 first passes through the second fixed wire block 408 at the lower end of the third sheet metal part 406 in the second photovoltaic panel side extension frame 4 on this side, and then passes through the first upper guide rope wheel 554 of the first steel rope guide wheel group 55 to turn, and finally is fixed to the upper winch of the double-layer winch 52;

[0045] S12. After confirming that the photovoltaic panel deployment and retraction steel rope 54 is correctly inserted and installed, tightening bolts are screwed into the first fixed conductor block 310, the movable conductor block 313, the second fixed conductor block 408, and the third fixed conductor block 411, respectively, so that the photovoltaic panel deployment and retraction steel rope 54 is fixed to the first fixed conductor block 310, the movable conductor block 313, the second fixed conductor block 408, and the third fixed conductor block 411, so that the photovoltaic panel deployment and retraction steel rope 54 can pull the first photovoltaic panel side extension frame 3 and the second photovoltaic panel side extension frame 4 through the first fixed conductor block 310, the movable conductor block 313, the second fixed conductor block 408, and the third fixed conductor block 411 to perform telescopic movement;

[0046] S2. After completing the interlaced assembly of the photovoltaic panel unfolding and retracting steel rope 54 in step S1, the specific stretching activity process of the photovoltaic panel stable telescopic structure is: the driving motor 53 is driven clockwise to drive the driving motor 53 to rotate, and the upper winch of the double-layer winch 52 is used to release the photovoltaic panel unfolding and retracting steel rope 54, while the lower winch of the double-layer winch 52 is wound up to retract the photovoltaic panel unfolding and retracting steel rope 54, so that the photovoltaic panel unfolding and retracting steel rope 54 simultaneously pulls the first fixed wire block 310, the movable wire block 313, the second fixed wire block 408 and the third fixed wire block 411, and waits until the first photovoltaic panel side extension frame 3 and the second photovoltaic panel side extension frame 4 are stably slid out of the vehicle at the same time. The top box frame body 1, at this time, the first sheet metal male head 309 is connected to the first photovoltaic panel female seat on one of the first side extension guide rails 301, the second sheet metal male head 314 is connected to the first photovoltaic panel female seat on the other first side extension guide rail 301, the third sheet metal male head 407 is connected to the second photovoltaic panel side female seat on one of the second side extension guide rails 401, and the fourth sheet metal male head 410 is connected to the second photovoltaic panel side female seat on one of the second side extension guide rails 401, so that the photovoltaic panels installed in the unfolded first photovoltaic panel side extension frame 3 and the second photovoltaic panel side extension frame 4 are connected to the battery for storage through the solar invention;

[0047] S3. The specific process of the photovoltaic panel stable telescopic structure contracting after stretching is: the double-layer winch 52 is driven to rotate by driving the motor 53 counterclockwise, and the upper winch of the double-layer winch 52 is used to reel in the photovoltaic panel unfolding and pulling steel rope 54, while the lower winch of the double-layer winch 52 releases the photovoltaic panel unfolding and pulling steel rope 54, so that the photovoltaic panel unfolding and pulling steel rope 54 simultaneously pulls the first fixed wire block 310, the movable wire block 313, the second fixed wire block 408 and the third fixed wire block 411. At this time, the first sheet metal male head 309 and the second sheet metal male head 314 are also pulled out from the first photovoltaic panel female seat on the two first side extension guide rails 301, and the third sheet metal male head 407 and the fourth sheet metal male head 410 are pulled out from the second photovoltaic panel side female seat on the two second side extension guide rails 401, so that the retracted first photovoltaic panel side extension frame 3 and the second photovoltaic panel side extension frame 4 are disconnected from the battery to avoid short circuit.

[0048] It should be further explained that in step S2, since the movable conductor block 313 is installed on the photovoltaic panel unfolding and pulling steel rope 54, it is obliquely inserted from the second pressure rope guide wheel 573 to the stroke end of the single-layer steering wheel 58. During this process, the photovoltaic panel unfolding and pulling steel rope 54 pulls the movable conductor block 313 to drive the second sheet metal 311 to move toward the second pressure rope guide wheel 573. The movable conductor block 313 is gradually rotated downward and adjusted through the hinge 312 under the pulling of the photovoltaic panel unfolding and pulling steel rope 54 until the first photovoltaic panel side extension frame 3 is stably extended. At this time, the movable conductor block 313 is rotated downward and adjusted to the lowest angle through the hinge 312 of the photovoltaic panel unfolding and pulling steel rope 54.

The installation of the photovoltaic panel expansion and retraction steel rope: S11. One end of the photovoltaic panel unfolding and pulling rope is released from the lower winch of the double-layer winch, and then passes through the lower guide rope wheel of the first steel rope guide wheel group to be turned, and is pressed and guided by the rope guide wheel. After being led out from the rope guide wheel, it passes through the first fixed wire block, and is turned through the lower steering wheel of the double-layer steering wheel, so that the photovoltaic panel unfolding and pulling rope is directly tilted and led to the second steel rope guide wheel group, and is turned through the second lower guide rope wheel of the second steel rope guide wheel group, and is then pressed and guided by the second rope guide wheel, so that the photovoltaic panel unfolding and pulling rope passes through the movable wire block. At this time, the photovoltaic panel unfolding and pulling rope is tilted and inserted into the single-layer steering wheel, and then from the single-layer The steering wheel turns and inserts into the second upper guide rope wheel of the second steel rope guide wheel group. When the photovoltaic panel unfolding and pulling steel rope passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope first inserts into the third fixed wire block at the lower end of the fourth sheet metal part in the second photovoltaic panel side extension frame on this side, and then turns through the second upper guide rope wheel of the second steel rope guide wheel group to insert into the upper steering wheel of the double-layer steering wheel for steering. When the photovoltaic panel unfolding and pulling steel rope passes through this section of travel, the photovoltaic panel unfolding and pulling steel rope first inserts into the second fixed wire block at the lower end of the third sheet metal part in the second photovoltaic panel side extension frame on this side, and then turns through the first upper guide rope wheel of the first steel rope guide wheel group, and finally is fixed to the upper winch of the double-layer winch; S12. After ensuring that the photovoltaic panel deployment and retraction wires are correctly inserted and installed, tighten the compression bolts into the first fixed conductor block, the movable conductor block, the second fixed conductor block, and the third fixed conductor block, respectively, so that the photovoltaic panel deployment and retraction wires are fixed to the first fixed conductor block, the movable conductor block, the second fixed conductor block, and the third fixed conductor block.
