Detailed implementation manners

[0019] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0020] Figure 1 It is a schematic diagram of the first embodiment of the in-vehicle display device of the present application. Figure 2 It is a schematic diagram of the connection between the lifting system and the solar panel in the first embodiment of the in-vehicle display device of the present application.

Figure 4 It is a schematic diagram of the connection between the frame and the solar panel in the first embodiment of the in-vehicle display device of the present application. As Figures 1 to 4 shown, the embodiment of the present application discloses an in-vehicle display device 100 for connecting to the center console 300 of the vehicle 10. The in-vehicle display device 100 includes a solar panel 110, a display 120, and a lifting system 130; the lifting system 130 is arranged in the center console 300; the lifting system 130 is connected to the solar panel 110, and the solar panel 110 is electrically connected to the display 120; when the in-vehicle display device 100 is in the first state, the lifting system 130 controls the solar panel 110 to lift relative to the center console 300; when the in-vehicle display device 100 is in the second state, the lifting system 130 controls the solar panel 110 to be embedded in the center console 300.

[0021] This application improves the in-vehicle display device 100. By installing the solar panel 110 used to power the display 120 of the in-vehicle display device 100 inside the center console 300 of the vehicle 10 and connecting it to the solar panel 110 through the lifting system 130, when the in-vehicle display device 100 is in the first state, the lifting system 130 controls the solar panel 110 to lift relative to the center console 300, so that the solar panel 110 can be exposed outside the center console 300, and the light irradiated into the vehicle body 200 from the external environment can be received by the solar panel 110. Thus, the solar panel 110 can fully absorb solar energy and convert the received solar energy into electrical energy for storage; when the in-vehicle display device 100 is in the second state, the lifting system 130 controls the solar panel 110 to be embedded inside the center console 300, so that the solar panel 110 is protected by the center console 300, effectively avoiding damage to the solar panel 110 caused by external environmental factors; thereby improving the problem that the solar panel 110 of the in-vehicle display device 100 is easily damaged due to long-term exposure outside the vehicle body 200.

[0022] It should be noted that the first state of the in-vehicle display device 100 can be understood as the in-vehicle display device 100 being in an operating state, and the second state can be understood as the in-vehicle display device 100 being in a standby state. In this application, when the vehicle 10 is in a driving state, the in-vehicle display device 100 is in a standby state. At this time, the solar panel 110 is embedded inside the center console 300, and the solar panel 110 is located on the surface of the center console 300 to absorb solar energy; when the vehicle 10 is in a parking state, the in-vehicle display device 100 is in an operating state. At this time, the solar panel 110 lifts relative to the center console 300, thereby expanding the area for receiving external ambient light and maximizing the utilization of solar energy.

[0023] Furthermore, the lifting system 130 includes a power component 131 and a bracket component 140. The bracket component 140 is connected between the solar panel 110 and the center console 300, and the power component 131 is connected to the bracket component 140; when the in-vehicle display device 100 is in the first state, the power component 131 controls the bracket component 140 to lift relative to the center console 300; when the in-vehicle display device 100 is in the second state, the power component 131 controls the bracket component 140 to be embedded inside the center console 300.

[0024] In this application, since the solar panel 110 is installed on the bracket assembly 140, the lifting and embedding actions of the bracket assembly 140 are controlled by the power assembly 131, so that the solar panel 110 installed on the bracket assembly 140 can also follow the bracket assembly 140 to lift or embed relative to the center console 300. As a result, the solar panel 110 will not be exposed to the external environment for a long time, which is beneficial to extending the service life of the solar panel 110.

[0025] When the in-vehicle display device 100 is in the first state (operating state), the power assembly 131 controls the bracket assembly 140 to lift relative to the center console 300, so that the solar panel 110 follows the lifting of the bracket assembly 140 and is lifted. The solar panel 110 is exposed out of the center console 300 and completely exposed to the environment inside the vehicle, so that the solar panel 110 can receive more light irradiated from the external environment. As a result, it is beneficial for the solar panel 110 to convert more light energy into electrical energy and improve the energy storage efficiency of the solar panel 110.

[0026] When the in-vehicle display device 100 is in the second state (standby state), the power assembly 131 controls the bracket assembly 140 to be embedded into the center console 300, so that the solar panel 110 follows the bracket assembly 140 to be embedded into the center console 300. Only the surface of the solar panel 110 is exposed outside the center console 300. This can not only ensure to a certain extent that the solar panel 110 receives light and converts light energy into electrical energy, without affecting the power supply of the in-vehicle display device 100 by the solar panel 110; but also effectively avoid collisions or scratches on the solar panel 110 caused by external objects inside the center console 300, thus extending the service life of the solar panel 110.

[0027] Specifically, the bracket assembly 140 includes a frame 141, a support member 150 and a cross beam 160. The cross beam 160 is connected to the cavity 310 of the center console 300, and the support member 150 is located between the frame 141 and the cross beam 160; one end of the support member 150 is connected to the cross beam 160, and the other end is rotatably connected to the frame 141, and the frame 141 is connected to the solar panel 110; the power assembly 131 includes an electric push rod 132 and a control main board 133. The electric push rod 132 is connected between the cross beam 160 and the frame 141, and the control main board 133 is installed on the cross beam 160; the electric push rod 132 is electrically connected to the control main board 133, and the control main board 133 controls the electric push rod 132 to extend or retract a preset distance along its own axis direction to push the frame 141 to lift relative to the center console 300, or pull the frame 141 to be embedded into the center console 300.

[0028] In this embodiment, the cross beam 160 is connected to the cavity 310 of the center console 300, so that the cross beam 160 can provide support for other components within the center console 300. There may be two support members 150. One end of each of the two support members 150 is respectively connected to opposite sides of the cross beam 160, and the other ends are respectively rotatably connected to both ends of the frame 141 through pin shafts. On the one hand, the support members 150 can support the frame 141 to ensure the stability of the solar panel 110 mounted on the frame 141. On the other hand, the frame 141 connected to the support members 150 can also be rotated. When the control main board 133 controls the electric push rod 132 to extend, the electric push rod 132 will push the frame 141 out of the center console 300. At this time, the frame 141 rotates to one side, driving the solar panel 110 mounted on the frame 141 to rotate accordingly, achieving the lifting effect of the solar panel 110 relative to the center console 300, so that the solar panel 110 can receive sunlight in a larger range and improve the energy conversion efficiency.

[0029] When the control main board 133 controls the electric push rod 132 to contract, the electric push rod 132 will pull the frame 141 into the center console 300. At this time, the frame 141 rotates to the other side, driving the solar panel 110 mounted on the frame 141 to rotate, so that it is re-embedded into the center console 300, and the center console 300 is used to protect the solar panel 110, avoiding the situation that the solar panel 110 is easily damaged due to long-term exposure to the external environment. That is, in this application, the longitudinal rotation and lifting of the solar panel 110 are realized by driving the frame 141 to rotate through the electric push rod 132.

[0030] Further, a slide rail 142 is provided on the frame 141. One end of the electric push rod 132 is movably connected to the slide rail 142, and one end of the electric push rod 132 can move along the extension direction of the slide rail 142. The slide rail 142 includes a first end 143 and a second end 144. When one end of the electric push rod 132 connected to the slide rail 142 moves to the first end 143, the frame 141 drives the solar panel 110 to rotate relative to the center console 300 to the maximum angle. When one end of the electric push rod 132 connected to the slide rail 142 moves to the second end 144, the frame 141 drives the solar panel 110 to be in the same horizontal plane as the tabletop of the center console 300.

[0031] Since one end of the electric push rod 132 is movably connected to the slide rail 142 on the frame 141, the slide rail 142 limits one end of the electric push rod 132, so that one end of the electric push rod 132 can only move within the slide rail 142; when the control main board 133 controls the electric push rod 132 to extend, the electric push rod 132 will push the frame 141 out of the center console 300, causing the frame 141 to rotate to one side. During the rotation of the frame 141, the slide rail 142 on the frame 141 will move relative to the connection end of the electric push rod 132 and the slide rail 142. During the movement of one end of the electric push rod 132 within the slide rail 142, the solar panel 110 is gradually lifted. When the end of the electric push rod 132 connected to the slide rail 142 moves to the first end 143, the frame 141 drives the solar panel 110 to rotate relative to the center console 300 to the maximum angle. The solar panel 110 can better receive the light in the external environment and convert the absorbed light energy into electric energy, which is beneficial to improving the energy conversion efficiency of the solar panel 110.

[0032] When the control main board 133 controls the electric push rod 132 to contract, the electric push rod 132 will pull the frame 141 into the center console 300. At this time, the frame 141 rotates to the other side. During the rotation of the frame 141, the slide rail 142 on the frame 141 will move relative to the connection end of the electric push rod 132 and the slide rail 142. During the movement of one end of the electric push rod 132 within the slide rail 142, the solar panel 110 gradually descends. When the end of the electric push rod 132 connected to the slide rail 142 moves to the second end 144, the frame 141 drives the solar panel 110 to just fit into the center console 300, and the outer surface of the solar panel 110 is flush with the tabletop of the center console 300. This not only allows the solar panel 110 to continue receiving light and converting the light energy into electric energy, but also does not affect the beauty of the center console 300, and uses the center console 300 to protect the solar panel 110 to prevent damage caused by the long-term exposure of the solar panel 110 to the external environment.

[0033] In the embodiment of the present application, the electric push rod 132 is used to push the frame 141 to rotate in a telescopic manner to realize the rotation and lifting of the solar panel 110. It is also possible to directly set a motor on the frame 141 and use the motor to drive the frame 141 to rotate to realize the rotation and lifting of the solar panel 110. The present application only takes the electric push rod 132 as an example for illustration, and is not limited to only using the electric push rod 132 to push the frame 141 to rotate.

[0034] In addition, in order to ensure that the frame 141 rotates more smoothly under the influence of its own weight, two electric push rods 132 can be provided and connected to both sides of the cross beam 160 respectively. The two electric push rods 132 are used to push the frame 141 simultaneously, further improving the stability of the rotation of the frame 141.

[0035] Furthermore, the bracket assembly 140 further includes a connecting member 170, a first rotating shaft 171 and a fixing member 172. The fixing member 172 is connected to the frame 141, the connecting member 170 is connected to the solar panel 110, one end of the first rotating shaft 171 is connected to the connecting member 170, and the other end is rotatably connected to the fixing member 172; the lifting system 130 further includes a transmission assembly 180. The transmission assembly 180 is arranged on the frame 141 and is connected to the end of the first rotating shaft 171 away from the connecting member 170. The transmission assembly 180 is used to drive the first rotating shaft 171 to rotate.

[0036] In this embodiment, the solar panel 110 is installed on the connecting member 170, fixedly connected to the connecting member 170 through one end of the first rotating shaft 171, and rotatably connected to the fixing member 172 on the frame 141 through the other end. The transmission assembly 180 drives the first rotating shaft 171 to rotate. When the first rotating shaft 171 rotates, it will drive the connecting member 170 to rotate, so that the connecting member 170 can drive the solar panel 110 to rotate along the axis of the first rotating shaft 171. In this way, the lateral angle adjustment of the solar panel 110 is realized, which is beneficial to improving the accuracy of light seeking of the solar panel 110.

[0037] Specifically, the frame 141 includes a support frame 145 and two frame rotating shafts 146. The two frame rotating shafts 146 are respectively located on both sides of the support frame 145 and connected to the support frame 145, and the end of the frame rotating shaft 146 away from the support frame 145 is rotatably connected to the support member 150; the fixing member 172 is connected to the support frame 145; the transmission assembly 180 includes a worm 181, a gear set 182 and a first motor 183; both ends of the worm 181 are rotatably connected to the frame rotating shafts 146 respectively, the gear set 182 is installed at the end of the first rotating shaft 171 away from the connecting member 170, and the gear set 182 is connected to the worm 181; the first motor 183 is fixed to the support member 150 and connected to the worm 181 for driving the worm 181 to rotate; the worm 181 drives the gear set 182, and the gear set 182 drives the first rotating shaft 171 to rotate along its own central axis.

[0038] Among them, the first motor 183 can be a reduction motor. In this embodiment, one end of the first rotating shaft 171 is connected to the fixing member 172 and a gear set 182 is installed at the same time. The gear set 182 is also connected to the worm 181 in a gear meshing manner. One end of the worm 181 is connected to the reduction motor. The worm 181 uses the reduction motor as a power source. The reduction motor drives the worm 181 to rotate. The worm 181 drives the gear set 182, and the gear set 182 drives the first rotating shaft 171 to rotate along its own central axis, thereby driving the solar panel 110 to rotate. It realizes the single reduction motor to drive the solar panel 110 to rotate synchronously along its own rotating shaft.

[0039] Of course, there can be multiple solar panels 110 in this application. Each solar panel 110 is connected to the frame 141 through the connecting member 170, the first rotating shaft 171 and the fixing member 172. The gear set 182 is installed on each first rotating shaft 171 connected to the solar panel 110. Multiple gear sets 182 are simultaneously connected to the worm 181. The worm 181 uses the reduction motor as a power source and drives multiple gear sets 182 at the same time. Multiple gear sets 182 drive the solar panels 110 connected to their respective corresponding first rotating shafts 171 to rotate, realizing the single reduction motor to drive multiple solar panels 110 to rotate synchronously along their own rotating shafts; since the driving principle is the same as the above solution, therefore, the solution of using one more worm 181 to drive multiple solar panels 110 through multiple gear sets 182 at the same time will not be elaborated here.

[0040] Multiple solar panels 110 can be arranged at equal intervals along the axial direction of the frame 141, and the specific installation position is based on the overall gravity balance of the frame 141.

[0041] Based on the above content, it can be known that the light seeking of the solar panel 110 in this application is divided into two dimensions, namely longitudinal and transverse. The electric push rod 132 is used to control the longitudinal rotation of the solar panel 110, and the first motor 183 is used to control the transverse rotation of the solar panel 110 through the worm 181 and the gear set 182, so as to control the solar panel 110 to be adjusted to any position and any angle, which is beneficial for the solar panel 110 to automatically seek light according to the actual irradiation direction of the light.

[0042] Figure 5 It is a schematic diagram of the second embodiment of the in-vehicle display device of this application, as Figure 5As shown, vehicle 10 includes an on-vehicle battery 400. The on-vehicle display device 100 further includes a control module 600 and a detection module 500. The detection module 500 is connected to the solar panel 110 for detecting the power of the solar panel 110. The control module 600 is electrically connected to the solar panel 110, the display 120, and the on-vehicle battery 400 respectively. The control module 600 is used to switch the power supply circuit of the solar panel. When the detection module 500 detects that the power of the solar panel 110 is in the first power state, the control module 600 controls the solar panel 110 to supply power to the display 120. When the detection module 500 detects that the power of the solar panel 110 is in the second power state, the control module 600 controls the solar panel 110 to supply power to the on-vehicle battery 400.

[0043] What is different from the previous embodiment in this embodiment is that this embodiment also improves the power supply method of the solar panel 110. By the detection module 500, the power state of the solar panel 110 is monitored in real time, and the information is transmitted to the control module 600, realizing the function of automatically switching the power supply circuit according to the power state of the solar panel 110. Among them, the first power state can be understood as the state when the power is higher than 20%, and the second power state can be understood as the state when the power is lower than 20%. The specific power state can be set by the user. This application only takes the power being higher or lower than 20% as an example for power supply switching. The specific working principle is as follows: When the detection module 500 detects that the power of the solar panel 110 is in the first power state (when the power is higher than 20%), the detection module 500 transmits the detection signal to the control module 600, and the control module 600 supplies the electric energy of the solar panel 110 for the on-vehicle display device 100 to use, ensuring the normal operation of the on-vehicle display device 100.

[0044] When the detection module 500 detects that the solar panel 110 is in the second power state (when the power is lower than 20%), the detection module 500 transmits the detection signal to the control module 600, and the control module 600 switches the solar panel 110 to charge the on-vehicle battery 400 to prevent the battery from losing power, thereby maximizing the utilization of the electric energy generated by the solar panel 110.

[0045] That is, in this embodiment, the control module 600 distributes the electric energy generated by the solar panel 110, avoiding waste of electric energy. When the power is sufficient, it preferentially meets the needs of the on-vehicle display device 100. When the power is relatively low, it stores the electric energy in the on-vehicle battery 400 for subsequent use by other devices of the vehicle 10 or for power supply under the condition of no light, improving the overall energy utilization efficiency of the vehicle 10 system.

[0046] Figure 6 This is a schematic diagram of an embodiment of the vehicle of this application, asFigure 6 As shown in the figure, an embodiment of the present application also discloses a vehicle 10, which includes a vehicle body 200. The vehicle 10 further includes the above-mentioned in-vehicle display device 100, and the in-vehicle display device 100 is connected to the vehicle body 200. The in-vehicle display device 100 is used to display driving information or other picture information in the vehicle body 200, thereby enriching the driving experience.

[0047] For the in-vehicle display device 100 usually installed in the vehicle 10, the solar panel 110 that powers the display 120 is installed on the top of the vehicle body 200, and being exposed to the external environment for a long time easily causes damage to the solar panel 110.

[0048] Based on the above problems, the present application has improved the in-vehicle display device 100 in the vehicle 10. By installing the solar panel 110 that powers the display 120 of the in-vehicle display device 100 inside the center console 300 of the vehicle 10 and connecting it to the solar panel 110 through the lifting system 130, when the in-vehicle display device 100 is in the first state, the lifting system 130 controls the solar panel 110 to lift relative to the center console 300, so that the solar panel 110 can be exposed outside the center console 300, and the light rays entering the vehicle body 200 from the external environment can be received by the solar panel 110, so that the solar panel 110 converts the received light energy into electrical energy and stores it; when the in-vehicle display device 100 is in the second state, the lifting system 130 controls the solar panel 110 to be embedded inside the center console 300, so that the solar panel 110 is protected by the center console 300, effectively avoiding damage to the solar panel 110 caused by external environmental factors. Thus, it improves the problem that the solar panel 110 of the in-vehicle display device 100 is easily damaged due to being exposed outside the vehicle body 200 for a long time; and further improves the quality of the vehicle 10.

[0049] Figure 7 It is a step diagram of the first embodiment of the control method of the in-vehicle display device of the present application; as Figure 7 As shown in the figure, an embodiment of the present application also discloses a control method for an in-vehicle display device 100, which is used to control the above-mentioned in-vehicle display device 100, and includes the steps: S1: Obtain the current time information; S2: Judge whether the current time information is within the first time interval. If so, control the in-vehicle display device 100 to be in the operating state; if not, control the in-vehicle display device 100 to be in the standby state; S3: Detect the power state of the vehicle 10; S4: When it is detected that the power state of the vehicle 10 is in the first power state, control the solar panel 110 of the in-vehicle display device 100 to be hidden inside the center console 300; S5: When it is detected that the power supply state of the vehicle 10 is in the second power supply state, the solar panel 110 of the in-vehicle display device 100 is controlled to be lifted to the working position. Among them, when it is detected that the power supply state of the vehicle 10 is in the second power supply state, the light information is detected, and the position of the solar panel 110 is adjusted according to the obtained light information.

[0050] In this embodiment, a main control program can be built into the monitor 120 of the in-vehicle display device 100. The built-in main control program can be written using devices that can follow logic, such as single-chip microcomputers, programmable logic controllers, field-programmable gate arrays (FPGAs), etc. The main control program is used to call the clock function to obtain the current time information. Building a main control program with logical editing in the monitor 120 belongs to the conventional means in the art, and will not be elaborated in detail in this application.

[0051] Among them, the first time interval in this application can be from 6:00 to 19:00, or other time interval segments set by the user himself; in this embodiment, only the first time interval from 6:00 to 19:00 is used as an example for illustration.

[0052] When it is detected that the current time information is within the time interval from 6:00 to 19:00, the main control program built into the in-vehicle display device 100 controls the in-vehicle display device 100 to be turned on. At this time, the solar panel 110 connected to the monitor 120 is in an operating state, and can collect the light in the external environment, thereby converting the light energy into electrical energy and storing it; since the vehicle 10 is generally not in use during this time period, when the vehicle 10 is parked outdoors and collecting and storing energy from the external environmental light, it will not affect the driver's operation and driving, thus not affecting the driver's driving experience, and can also avoid the solar panel 110 consuming energy while storing energy, which is beneficial to improving the energy storage efficiency of the solar panel 110.

[0053] When it is detected that the current time information is not within the time interval from 6:00 to 19:00, the in-vehicle display device 100 only turns on the clock function, and other functions are all turned off (other functions include but are not limited to the operation of the solar panel 110, and the user can set the functions to be turned on or off through the main control program), that is, the in-vehicle display device 100 enters the sleep standby mode, thereby reducing the energy consumption of the in-vehicle display device 100.

[0054] In addition, a corresponding control system is provided in a general vehicle 10, and the control system is connected to the in-vehicle display device 100. Therefore, the control system of the vehicle 10 itself can also be used to control whether the in-vehicle display device 100 is in an operating or standby state by detecting vehicle 10 information. Controlling the operation or standby of the in-vehicle display device 100 and the activation or deactivation of some functions of the in-vehicle display device 100 through the control system of the vehicle 10 itself are conventional means in the art and will not be elaborated herein one by one.

[0055] Further, by detecting the power state of the vehicle 10 through the control system of the vehicle 10, it is possible to determine whether the in-vehicle display device 100 is in a first state or a second state, so as to control the lifting of the solar panel 110 to the working position or its embedding into the center console 300. When it is detected that the power state of the vehicle 10 is in a first power state, it can be determined that the in-vehicle display device 100 is in a second state, and then the solar panel 110 of the in-vehicle display device 100 is controlled to be hidden in the center console 300. When it is detected that the power state of the vehicle 10 is in a second power state, it can be determined that the in-vehicle display device 100 is in a first state, and then the solar panel 110 of the in-vehicle display device 100 is controlled to be lifted to the working position.

[0056] Among them, the first power state can be understood as the state where the vehicle 10 power is turned on, and the second power state can be understood as the state where the vehicle 10 power is turned off.

[0057] When a vehicle 10 power start signal is detected, the system determines that the vehicle has entered the driving state, and the control system sends an instruction to reset the electric push rod 132 and the reduction motor. The entire device is hidden in the internal storage cavity of the center console 300, and during the hidden state, it receives light and generates electricity, waiting for the next start signal. Since the vehicle 10 is likely to be in the driving and using period during this time, in order to avoid interference to the driver by the solar panel 110 during operation, the operation of the in-vehicle display device 100 can be turned off, thereby preventing the solar panel 110 of the in-vehicle display device 100 from lifting during the driving of the vehicle 10, which may cause problems such as blocking or other interference to the driver. This is beneficial to improving the driving experience of the driver while avoiding the long-term exposure of the solar panel 110 of the in-vehicle display device 100 to the external environment, thus helping to extend the service life of the solar panel 110.

[0058] When a vehicle 10 power off signal is detected, the control system determines that the vehicle 10 has entered the parking state. The control system can send a pulse instruction to the electric push rod through the motor driver, and the electric push rod 132 pushes the solar panel 110 to the working position. This can effectively increase the light receiving range of the solar panel 110, thereby improving the energy conversion efficiency of the solar panel 110.

[0059] That is, in the in-vehicle display device 100 of the present application, the operating state of the solar panel 110 can be divided into a hidden state and a lifted operating state. When the vehicle 10 power-on signal is detected, the control system determines that the vehicle 10 enters the driving state, and the solar panel 110 is in the hidden state, that is, the solar panel 110 is in the cavity 310 inside the center console 300. At this time, the solar panel 110 converts electrical energy while lying flat in the center console 300, and other components do not operate to ensure solar power generation without blocking the driver's line of sight; when the vehicle 10 power-off signal is detected, the control system determines that the vehicle 10 enters the parking state, and the control system can send a pulse command to the electric push rod 132 through the motor driver, and the electric push rod 132 pushes the solar panel 110 to lift to the working position to ensure that the solar panel 110 can better receive the light irradiated in the external environment and improve the photoelectric conversion efficiency of the solar panel 110.

[0060] It should be noted that in this embodiment, the control system of the vehicle 10 itself issues a pulse command through the motor driver to control the telescopic movement of the electric push rod 132, which is a conventional means in the art. The specific control methods and steps are not elaborated in this application.

[0061] Figure 8 It is a step diagram of the second embodiment of the control method of the in-vehicle display device of the present application. As Figure 8 shown, S5: When it is detected that the power state of the vehicle 10 is in the second power state, the step of controlling the solar panel 110 to lift to the working position further includes: S51: Execute the lift N times; S52: Each time the solar panel 110 is lifted, it rotates a preset angle; wherein, N is a natural number, and there is a retention time between two adjacent lifts.

[0062] The difference between this embodiment and the previous embodiment is that in this embodiment, in order to achieve better light collection of the solar panel 110, the lifting process of the solar panel 110 is not completed at one time, but is carried out step by step. The solar panel 110 is controlled to be lifted to the working position step by step, and a retention time is set between two adjacent lifts.

[0063] During the retention time, the light sensor set additionally can respond and feedback the currently collected light information during the retention time, and the main control program controls the transmission of the first motor 183 according to the light information collected by the light sensor, thereby driving the solar panel 110 to lift to the preset angle. Among them, the specific value of the retention time is based on the response time of the adopted light sensor, and the collected light information can be the light power.

[0064] Specifically, for example: when the preset angle of each lift is 10° and N is 4; when it is detected that the vehicle 10 power supply is in the off state, the lifting operation of the solar panel 110 is started, and the solar panel 110 is driven to rotate 10° each time. After 4 executions, the solar panel 110 rotates a total of 40°.

[0065] A certain retention time is set between two adjacent rotations to enable the light sensor to respond and feedback the currently collected light power value. The main control program will save the collected power value and its corresponding position information in real time.

[0066] When the solar panel 110 completes the traversal of all set angles, the main control program calculates the collected data to determine the maximum value of the light power and its corresponding position; subsequently, the main control program sends a pulse command to the electric push rod 132 to accurately adjust the position of the solar panel 110 to the position with the maximum light power, thereby achieving the optimal solar energy collection efficiency. That is, through the precise angle control and data feedback mechanism in this embodiment, it is beneficial to improve the energy collection performance of the solar panel 110.

[0067] In addition, the main control program of this application includes a sun-tracking function, that is, using the clock and timing module of the main control program to repeat the above operations at regular intervals to ensure that the solar panel 110 is located at the best light-receiving position and improve the solar power generation efficiency.
