Description

Technical Field

[0001] This invention relates to the field of solar drive technology, and in particular to an extended support mechanism for solar photovoltaic panels used in electric vehicles. Background Technology

[0002] Current solar photovoltaic (PV) modules are large and inconvenient to transport and carry, and adjustments such as angle are difficult. Other shortcomings include: solar panels are typically fixed structures consisting of multiple cells tightly arranged in series on a protective backsheet and mounted by a frame. Since the panels face upwards to receive sunlight, rain and snow can cause water seepage, and severe weather can severely impact the panels, damaging them. Furthermore, scratches or cracks can occur during transport, rendering the modules defective and affecting their usability. Additionally, the installation angle of residential solar PV modules is often fixed, failing to meet the specific angle requirements of electric vehicle customers. Summary of the Invention

[0036] See Figure 4This is a structural diagram of the support frame for the second layer of solar photovoltaic panels, which can extend or retract laterally to the left along the main support frame, and the first extension drive mechanism. The second layer solar photovoltaic panel support frame 0-2 includes three first guide rails 0-2-1 arranged at equal intervals and parallel to each other. A first baffle 0-2-5 is provided at both ends of each of the three first guide rails 0-2-1 (the first baffle 0-2-5 and the first guide rails 0-2-1 are connected by a first corner joint 0-2-6). The first extension drive mechanism 0-5 includes a first fixed motor 0-2-2, a first synchronous pulley 0-2-3, a first synchronous belt, and a first synchronous belt fixing seat 0-2-4. The first fixed motor 0-2-2 is fixedly mounted on the first baffle 0-2-5 on one side of the second layer solar photovoltaic panel support frame 0-2, and the first synchronous pulley 0-2-3 is mounted on... On the output shaft of the first fixed motor 0-2-2, one end of the first synchronous belt is fitted onto the first synchronous belt pulley 0-2-3, and the other end is fitted onto the first synchronous belt fixing seat 0-2-4. The first synchronous belt fixing seat 0-2-4 is fixedly installed on the first guide rail 0-2-1 in the middle of the second layer solar photovoltaic panel support frame 0-2 or fixedly installed on the first baffle 0-2-5 on the other side. A first guide rod is slidably installed in each first guide rail 0-2-1. The back of the second layer solar photovoltaic panel is connected to the first guide rod, and the back of the second layer solar photovoltaic panel is fixedly connected to the first synchronous belt through a connector. Thus, when the first fixed motor 0-2-2 is running, it will drive the second layer solar photovoltaic panel to move along the first guide rail 0-2-1, that is, to realize the second layer solar photovoltaic panel to extend or retract laterally to the left along the second layer solar photovoltaic panel support frame 0-2.

[0037] Furthermore, the second-layer solar photovoltaic panel support frame 0-2 is fixedly connected to the main support frame 0-1 via the first connector 0-2-7 located on the side.

[0038] See Figure 5This is a structural diagram of the support frame for the third-layer solar photovoltaic panel, which can extend or retract laterally to the right along the main support frame 0-1, and the second extension drive mechanism. The third-layer solar photovoltaic panel support frame 0-3 includes three equally spaced and parallel second guide rails 0-3-1. Second baffles 0-3-5 are provided at both ends of these three second guide rails 0-3-1 (the second baffles 0-3-5 and the second guide rails 0-3-1 are connected by second corner connectors 0-3-6). The second extension drive mechanism includes a second fixed motor 0-3-2, a second synchronous pulley 0-3-3, a second synchronous belt, and a second synchronous belt fixing seat 0-3-4. The second fixed motor 0-3-2 is fixedly mounted on the second baffle 0-3-5 on one side of the third-layer solar photovoltaic panel support frame 0-3, and the second synchronous pulley 0-3-3 is fixedly mounted on... On the output shaft of the second fixed motor 0-3-2, one end of the second synchronous belt is mounted on the second synchronous belt pulley 0-3-3, and the other end is mounted on the second synchronous belt fixing seat 0-3-4. The second synchronous belt fixing seat 0-3-4 is fixedly mounted on the second guide rail 0-3-1 in the middle of the third layer solar photovoltaic panel support frame 0-3 or fixedly mounted on the second baffle 0-3-5 on the other side. A second guide rod is slidably installed in each second guide rail 0-3-1. The back of the third layer solar photovoltaic panel is connected to the second guide rod, and the back of the third layer solar photovoltaic panel is fixedly connected to the second synchronous belt through a connector. Thus, when the second fixed motor 0-3-2 is running, it will drive the third layer solar photovoltaic panel to move along the second guide rail 0-3-1, that is, to realize the third layer solar photovoltaic panel to extend or retract laterally to the right along the third layer solar photovoltaic panel support frame 0-3.

[0039] Furthermore, the third-layer solar photovoltaic panel support frame 0-3 is fixedly connected to the main support frame 0-1 via a second connector 0-3-7 located on the side.

[0040] See Figure 6This is a structural diagram of the support frame for the fourth layer of solar photovoltaic panels, which can extend or retract vertically upward along the main support frame 0-1, and the third extension drive mechanism 0-6. The fourth layer solar photovoltaic panel support frame 0-4 includes three equally spaced and parallel third guide rails 0-4-1. The two ends of these three third guide rails 0-4-1 are connected to the reinforcement parts 0-9 of the main support frame 0-1 (the third guide rails 0-4-1 and the reinforcement parts 0-9 are connected by third corner connectors 0-4-5). In addition, the side walls of the two third guide rails 0-4-1 located on both sides are connected to the main support frame 0-1 through third connectors 0-4-6. The third extension drive mechanism 0-6 includes a third fixed motor 0-4-2, a third synchronous pulley 0-4-3, a third synchronous belt, and a third synchronous belt fixing seat 0-4-4. The third fixed motor 0-4-2 is fixedly installed on the fourth layer solar photovoltaic panel support. At the tail end of the third guide rail 0-4-1 in the middle of the frame 0-4, the third synchronous pulley 0-4-3 is connected to the output shaft of the third fixed motor 0-4-2. One end of the third synchronous belt is mounted on the third synchronous pulley 0-4-3, and the other end is mounted on the third synchronous belt fixing seat 0-4-4. The third synchronous belt fixing seat 0-4-4 is mounted on the front end of the third guide rail 0-4-1 in the middle of the fourth layer solar photovoltaic panel support frame 0-4. A third guide rod is slidably installed in each third guide rail 0-4-1. The back of the fourth layer solar photovoltaic panel is connected to the third guide rod, and the back of the fourth layer solar photovoltaic panel is fixedly connected to the third synchronous belt through a connector. Thus, when the third fixed motor 0-4-2 is running, it will drive the fourth layer solar photovoltaic panel to move along the third guide rail 0-4-1, that is, to realize the vertical upward extension or retraction of the fourth layer solar photovoltaic panel along the fourth layer solar photovoltaic panel support frame 0-4.

[0041] See Figure 7 The first, second, and third guide rods are all hexagonal guide rods, and each guide rod is equipped with a position sensor to detect the extended or retracted positions of the second, third, and fourth solar photovoltaic panels. In addition, an ultrasonic sensor is installed at the outer end of each guide rod to identify obstacles and prevent the second, third, and fourth solar photovoltaic panels from colliding with obstacles and causing damage during the extension or retraction process.

[0042] See Figure 8The erecting support mechanism 1 includes a guide rail group 1-1, a four-bar linkage mechanism 1-2, a movable slide 1-3, and a linear actuator motor 1-4. Specifically, three guide rail groups 1-1 are equally spaced and parallelly arranged on the frame of the erecting support mechanism 1. Each guide rail group includes two guide rails. A four-bar linkage mechanism 1-2 is set on each guide rail group 1-1. The top of the four-bar linkage mechanism 1-2 is connected to the hinge connection point 0-10 at the bottom of the main support frame 0-1. (The four-bar linkage mechanism 1-2 includes a first link, a second link, and a third link. The bottom end of the first link is hinged to the frame of the erecting support mechanism 1, the top end of the first link is hinged to one end of the second link, the other end of the second link is hinged to the third link, and the bottom end of the third link is hinged to the frame of the erecting support mechanism 1. The bottom end of the third link is connected to the first link.) The frame between the bottom ends of the connecting rods is equivalent to the fourth connecting rod, which is a fixed base. The top end of the third connecting rod is hinged to the hinge connection 0-10 at the bottom of the main support frame 0-1. A movable slide 1-3 is slidably installed on each guide rail group 1-1. Each movable slide 1-3 is equipped with a hinge. The bottom side frame of the main support frame 0-1 is hinged to the movable slide 1-3. The bottom end of the linear push rod motor 1-4 is hinged to the frame of the vertical support mechanism 1. The top end of the linear push rod motor 1-4 is hinged to one of the four-bar linkage mechanisms 1-2. The linear push rod motor 1-4 can drive the four-bar linkage mechanism 1-2 to move, and then the four-bar linkage mechanism 1-2 drives the main support frame 0-1 to rotate around the hinge axis on the movable slide 1-3, thereby realizing the pitch movement of the main support frame 0-1.

[0043] Furthermore, a long shaft 3 is provided on the bottom side frame of the main support frame 0-1. Figure 1 The long shaft 3 is provided with a connector 4, which is used to connect with the hinge on the movable slide 1-3 of the vertical support mechanism 1, and plays a guiding and limiting role in the pitching movement of the multi-layer support frame mechanism 0; at the same time, the long shaft 3 is equipped with a torsion spring at the corresponding position of the movable slide 1-3.

[0044] See Figure 9The rotating fixing mechanism 2 includes a slewing support bearing 2-1, a gear ring 2-2, a fixed support frame 2-3, and a fixed foot 2-4. The slewing support bearing 2-1 is mounted on the fixed support frame 2-3, and its upper end is connected to the frame of the erecting support mechanism 1. A conductive slip ring is installed in the center hole of the slewing support bearing 2-1 to detect the rotation angle of the erecting support mechanism 1. The gear ring 2-2 is coaxially arranged with the slewing support bearing 2-1 on the fixed support frame 2-3. Twelve rollers are arranged around the bottom circumference. The frame of the vertical support mechanism 1 rolls with the gear ring 2-2 through these rollers. A rotary drive motor is fixedly installed at the bottom of the frame of the vertical support mechanism 1. The rotary drive motor meshes with the gear ring 2-2 through gears, so that the solar photovoltaic panel extension support mechanism can rotate daily when the rotary drive motor is running. The fixed foot 2-4 is set at the bottom of the fixed support frame 2-3 and is used to connect with the foot on the top of the vehicle body through bolts to achieve fixed installation of the whole mechanism.

[0045] See Figure 10 When the extended support mechanism for the solar photovoltaic panel of the electric vehicle is in the closed state, only the first layer of solar photovoltaic panel 5 collects light and generates electricity, while the other three layers of solar photovoltaic panels do not participate in collecting light and generating electricity. The shell 6 is connected to the overall mechanism by adhesive bonding.

[0046] The present invention has been described above by way of example. It should be noted that any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort without departing from the core of the present invention fall within the protection scope of the present invention.
