Description

Technical Field

[0001] The utility model relates to the field of automobile solar energy equipment, in particular to a vehicle-mounted solar energy tracking system. Background Art

[0002] With the development of society, it is necessary to actively and steadily promote carbon peak and carbon neutrality, and accelerate the planning and construction of a new energy system. To achieve the "dual carbon" goal, energy is the main battlefield and electricity is the main force. Building a clean, low-carbon, safe and efficient energy system requires accelerating the construction of a new power system that adapts to the increasing proportion of new energy. my country has proposed that the total installed capacity of wind power and solar power generation will reach more than 1.2 billion kilowatts by 2030. With the high-quality and rapid development of photovoltaic power generation, photovoltaic power generation will play an important role in the construction of my country's new energy system. In the automotive field, photovoltaic charging stations and on-board charging are more widely used.

[0003] Solar panel tracking technology is a technology that keeps the solar panel tracking light and makes the light shine vertically on the solar panel to maintain maximum power generation efficiency. It usually uses two sets of photoresistors or photoelectric sensors to sense the light intensity, and adjusts the angle of the solar panel through circuit control to make the two sets of photoresistors sense the same light intensity. At this time, the solar panel reaches the best light angle.

[0004] For the vehicle-mounted tracking system, the solar panel assembly is usually placed on the roof, but due to the limited area and load-bearing capacity of the roof (generally speaking, the roof area of ​​a sedan is about 1.5 square meters, and the roof area of ​​an SUV is about 2 square meters. For example, the area of ​​the full skylight glass sunroof of the Xiaopeng P7 is 1.75 square meters), it is impossible to arrange a large number of solar panels to achieve the target power. The automatic tracking system can use limited solar panels to increase the utilization rate of the light source. Utility Model Content

[0005] The utility model aims to provide a vehicle-mounted solar light-chasing system, which has the characteristics of simple structure, stability, light weight, etc. The system can control the rotation movement in four directions and flip to expand the original light-receiving area.

[0006] In order to solve the above technical problems, the embodiment of the utility model provides a vehicle-mounted solar tracking system, comprising:

[0007] First Solar Panel;

[0008] A rotating mechanism, used to drive the first solar panel to rotate to achieve a light-chasing function;

[0009] A second solar panel is retracted in the light-chasing system and includes four solar panel units. The second solar panel is deployed or retracted by driving a connecting rod through an deployment mechanism;

[0010] The unfolding mechanism comprises:

[0012] The unfolding assembly rotates under the drive of the second motor, driving the connecting rod to rotate to unfold or retract the second solar panel;

[0013] There are four groups of connecting rods, one end of each of which is rotatably connected to the deployment assembly.

[0016] A third motor is installed on the base, and the third motor is used to drive the flipping mechanism to rotate and drive the first solar panel and the second solar panel to flip;

[0017] A lifting gear meshingly connected with an output end of the third motor;

[0018] A lifting support rod, one end of which is fixedly connected to the lifting gear and the other end of which is movably connected to the limit slide

[0019] In the tank;

[0020] A limiting slide groove, used to limit the rotation range of the lifting support rod;

[0021] The base is used to support the light-chasing system and install the light-chasing system on the roof.

[0022] The vehicle-mounted solar tracking system provided by the utility model includes a first solar panel located on the top layer, and a second solar panel that can be retracted or unfolded in a translational manner; the second solar panel can be unfolded by an unfolding mechanism, and the first solar panel and the second solar panel can be controlled by a rotating mechanism to realize a rotation action, and a flipping action can be realized by a flipping mechanism to adjust the inclination angle of the first solar panel and the second solar panel.

[0023] The lifting gear is driven to rotate by the third motor to change the angle of the lifting support rod, so that one end of the lifting support rod in the limiting slide slot slides in the limiting slide slot, thereby changing the inclination angle of the first solar panel and the second solar panel. The flipping angle is from horizontal to a downward tilt of 45 degrees, and is limited by the limiting slot to prevent collision with the base and surrounding objects.

[0024] The utility model flexibly uses three types of mechanisms, namely gears, motors and connecting rods, has a simple structure and complete functions. Waterproofing, windproofing and load strength need to be considered in the actual mass production process, and the value of popularization and application is very high.

[0025] In addition, the rotating mechanism comprises:

[0026] A first motor, used to provide power for the rotating mechanism;

[0027] A rotating gear is meshed and connected with the output end of the first motor, and the rotating gear is driven to rotate by the first motor;

[0028] A motor bracket, one end of which is hingedly mounted on the base, and the first motor is fixedly mounted on the bottom of the motor bracket;

[0029] An intermediate bracket, rotatably connected to the motor bracket;

[0030] The rotating bracket comprises a fixing portion and a sleeve, wherein the fixing portion is fixedly connected to the intermediate bracket, and the sleeve passes through the motor bracket and the intermediate bracket and is fixedly connected to the rotating gear;

[0031] Wherein, the rotating gear, the motor bracket, the intermediate bracket and the rotating bracket are coaxially arranged.

[0032] In addition, the first motor drives the rotating gear to rotate, and the rotating gear can drive the intermediate bracket and the rotating bracket to rotate at the center position of the motor bracket, so that the first solar panel and the second solar panel can rotate 360 ​​degrees.

[0033] In addition, the second motor is fixedly mounted on the fixing portion of the rotating bracket.

[0034] In addition, the second solar panel includes a first auxiliary solar panel deployed along the x-axis and a second auxiliary solar panel deployed along the y-axis.

[0035] In addition, the four groups of connecting rods include two groups of first connecting rods connected to the first auxiliary solar panel, and two groups of second connecting rods connected to the second auxiliary solar panel.

[0036] When the deployment mechanism is working, it can drive the first connecting rod to move, drive the first auxiliary solar panel to expand or shrink along the x-axis, and can simultaneously drive the second connecting rod to move, drive the second auxiliary solar panel to expand or shrink along the y-axis.

[0037] In addition, the expansion component includes:

[0042] The second motor can drive the unfolding gear to rotate, thereby driving the first turntable and the second turntable to rotate. Since one end of the connecting rod is connected to the second solar panel, and the other end is connected to the first turntable or the second turntable respectively, when the first turntable and the second turntable rotate driven by the unfolding gear, the connecting rod will move along the tangent of the first turntable and the second turntable, thereby causing the second solar panel to translate inward or outward.

[0043] In addition, the support column passes through between the two first auxiliary solar panels, so that the second turntable is located between the first auxiliary solar panel and the second auxiliary solar panel.

[0044] In addition, such a design can effectively prevent the first auxiliary solar panel and the second auxiliary solar panel from colliding, and can make the size of the second solar panel close to half of the first solar panel at most, thereby achieving better light energy conversion efficiency.

[0045] In addition, a first slideway is provided at the bottom of the first solar panel along the x-axis, and the first auxiliary solar panel is slidably connected in the first slideway;

The system has a variety of control methods for light-chasing, which can be adapted to manual control and automatic control. The manual control methods include vehicle computer, mobile phone APP and button switch control, but it can be understood that the specific signal connection method of the system can be designed according to the specific vehicle. For example, in family cars and industrial vehicles, the requirements for control methods are different, so different software or control methods can also be designed according to the use requirements. Therefore, the specific control method is not within the scope of the utility model. In general, the controller will move in the order of rotation → unfolding → flipping. The order is opposite when stopping work. First, flip to the horizontal state of the solar panel, and then close and rotate until it returns to the initial state.

The system has the characteristics of simple structure, stability, and light weight.

[0085] In addition, the intermediate bracket 24 is rotatably connected to the motor bracket 23 .

[0086] In addition, the rotating bracket 25 includes a fixing portion and a sleeve, the fixing portion is fixedly connected to the intermediate bracket 24 , and the sleeve passes through the motor bracket 23 and the intermediate bracket 24 and is fixedly connected to the rotating gear 22 .

[0087] The rotating gear 22 , the motor bracket 23 , the intermediate bracket 24 and the rotating bracket 25 are coaxially arranged.

[0088] In addition, the first motor 21 drives the rotating gear 22 to rotate, and the rotating gear 22 can drive the intermediate bracket 24 and the rotating bracket 25 to rotate at the center position of the motor bracket 23, so that the first solar panel 1 and the second solar panel can rotate 360 ​​degrees.

[0089] In addition, if Figure 5 As shown, the second solar panel 3 is retracted in the light-chasing system, and includes four solar panel units. The second solar panel 3 is expanded or retracted by driving the connecting rod through the expansion mechanism.

[0090] In addition, if Figure 7-9 As shown, the second solar panel 3 includes a first auxiliary solar panel 31 extended along the x-axis and a second auxiliary solar panel 32 extended along the y-axis.

[0091] In addition, the unfolding mechanism includes a second motor 41, an unfolding assembly and a connecting rod.

[0092] In addition, the second motor 41 is used to drive the unfolding mechanism. In addition, the second motor 41 is fixedly mounted on the fixing portion of the rotating bracket 25 .

[0093] In addition, the unfolding assembly rotates under the drive of the second motor 41, driving the connecting rod to rotate to unfold or retract the second solar panel 3; in addition, the unfolding assembly includes a turntable bracket 44, an unfolding gear 45, a first turntable 46 and a second turntable 47.

[0094] In addition, the turntable bracket 44 includes a fixing portion and a sleeve.

[0095] In addition, the unfolding gear 45 is mounted on the sleeve of the turntable bracket 44 , and the unfolding gear 45 is meshingly connected with the second motor 41 .

[0096] In addition, the first turntable 46 is fixedly connected to the turntable bracket 44 , and the first turntable 46 is provided with a first connecting structure, and the first connecting structure is rotatably connected to the two groups of first connecting rods 42 .

[0097] In addition, the second turntable 47 is fixedly connected to the turntable bracket 44 through a support column 48 , and the second turntable 47 is provided with a second connection structure, and the second connection structure is rotatably connected to the two sets of second connecting rods 43 .

[0098] In addition, the support column 48 passes between the two first auxiliary solar panels 31, so that the second turntable 47 is located between the first auxiliary solar panel 31 and the second auxiliary solar panel 32. In addition, this design can effectively prevent the first auxiliary solar panel 31 and the second auxiliary solar panel 32 from colliding, and can make the size of the second solar panel designed to be close to half of the first solar panel at most, so as to achieve better light energy conversion efficiency.

[0099] Four groups of connecting rods are provided, one end of the four groups of connecting rods is rotatably connected to the unfolding assembly, and the other end is rotatably connected to the second solar panel 3; in addition, the four groups of connecting rods include two groups of first connecting rods 42 connected to the first auxiliary solar panel 31, and two groups of second connecting rods 43 connected to the second auxiliary solar panel 32.

[0100] When the unfolding mechanism is working, the second motor 41 can drive the unfolding gear 45 to rotate, thereby driving the first turntable 46 and the second turntable 47 to rotate. Since one end of the connecting rod is connected to the second solar panel, and the other end is connected to the first turntable 46 or the second turntable 47 respectively, when the first turntable 46 and the second turntable 47 rotate under the drive of the unfolding gear 45, the first connecting rod 42 and the second connecting rod 43 will move along the tangent of the first turntable 46 and the second turntable 47, thereby driving the first auxiliary solar panel 31 to expand or contract along the x-axis, and the second auxiliary solar panel 32 to expand or contract along the y-axis.

[0101] like Figure 1-4 As shown, the flipping mechanism is used to drive the first solar panel 1 and the second solar panel 3 to flip, and includes a third motor 51 , a lifting gear 52 , a lifting support rod 53 and a limiting slide groove 54 .

[0102] The third motor 51 is installed on the base 6 , and is used to drive the flipping mechanism to rotate and drive the first solar panel 1 and the second solar panel 3 to flip.

[0104] One end of the lifting support rod 53 is fixedly connected to the lifting gear 52 , and the other end is movably connected to the limiting sliding groove 54 .

[0105] The limiting slide groove 54 is used to limit the rotation range of the lifting support rod 53 . In addition, the limiting slide groove 54 is installed at the bottom of the motor bracket 23 .

[0106] like Figure 6 As shown, when the environment is at different times and the sun is at different angles, the lifting gear 52 is driven to rotate by the third motor 51 to change the angle of the lifting strut 53, so that one end of the lifting strut 53 in the limiting slide groove 54 slides in the limiting slide groove 54, thereby changing the inclination angle of the first solar panel 1 and the second solar panel, so that the first solar panel 1 and the second solar panel are always facing the sunlight, thereby achieving the light-chasing effect. The flipping angle is from horizontal to a downward tilt of 45 degrees, and is limited by the limiting slide groove 54 to prevent collision with the base 6 and surrounding objects.

[0107] The base 6 is used to support the light-chasing system and install the light-chasing system on the roof.

[0108] In addition, the base 6 includes a supporting portion for connecting to the roof and a mounting portion for mounting the motor bracket 23 .

[0109] In addition, in the utility model, whether it is the rotating gear 22, the unfolding gear 45 or the lifting gear 52, they can all be fixed by shafts and pins, and whether it is a rotating mechanism, an unfolding mechanism or a lifting mechanism, they can all be fixedly connected by means of bolts and nuts, and a sleeve will be provided outside the bolt.

[0111] In addition, in the present invention, a gasket 26 may be provided to prevent friction damage between adjacent structures in the system.

[0112] It is understandable that the vehicle-mounted solar light-chasing system provided by the utility model is equipped with a controller for control, which controls the unfolding, rotation and flipping of the solar panel respectively to realize the light-chasing function. The system has a variety of control methods for achieving light-chasing, which can be adapted to manual control and automatic control. The manual control methods include vehicle computer, mobile phone APP and button switch control, but it is understandable that the specific signal connection method of the system can be designed according to the specific vehicle. For example, in family cars and industrial vehicles, the requirements for control methods are different, so different software or control methods can also be designed according to the use requirements. Therefore, the specific control method is not within the scope of the present utility model.

[0113] In addition, it is understandable that the first solar panel 1 and the second solar panel provided by the utility model can be improved in a customized manner and can be designed according to specific needs such as vehicle type and usage environment, taking into full consideration the effect of sunlight refraction angle on its capture of light sources and environmental impact.
