DETAILED DESCRIPTION

[0036] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] Figure 1 This is a schematic diagram of the first embodiment of the vehicle-mounted display device of the present application. Figure 2 This is a schematic diagram of the connection between the lifting system and the solar panel in the first embodiment of the vehicle-mounted display device of the present application; Figure 3 This is a schematic diagram of the connection between the electric push rod and the slide rail in the first embodiment of the vehicle-mounted display device of the present application; Figure 4 Schematic diagram of the connection between the frame and the solar panel in the first embodiment of the vehicle-mounted display device of the present application; Figures 1 to 4 As shown, an embodiment of the present application discloses a vehicle-mounted display device 100 for connecting to a center console 300 of a vehicle 10. The vehicle-mounted display device 100 includes a solar panel 110, a display 120, and a lifting system 130. The lifting system 130 is disposed 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 vehicle-mounted display device 100 is in a first state, the lifting system 130 controls the solar panel 110 to rise relative to the center console 300. When the vehicle-mounted display device 100 is in a second state, the lifting system 130 controls the solar panel 110 to be embedded in the center console 300.

[0038] The present application improves the vehicle-mounted display device 100 by installing a solar panel 110 for powering a display 120 of the vehicle-mounted display device 100 in the center console 300 of the vehicle 10 and connecting the solar panel 110 to the solar panel 110 through a lifting system 130. When the vehicle-mounted display device 100 is in a first state, the lifting system 130 controls the solar panel 110 to rise relative to the center console 300, so that the solar panel 110 can be exposed outside the center console 300, and the light from the external environment that shines into the vehicle body 200 can be reflected by the solar panel. 110 receives the solar energy, so that the solar panel 110 can fully absorb the solar energy and convert the received solar energy into electrical energy for storage; and when the vehicle-mounted 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, 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 vehicle-mounted display device 100 is easily damaged due to being exposed to the outside of the vehicle body 200 for a long time.

[0039] It should be noted that the first state of the vehicle-mounted display device 100 can be understood as the vehicle-mounted display device 100 is in an operating state, and the second state can be understood as the vehicle-mounted display device 100 is in a standby state. In the present application, when the vehicle 10 is in a driving state, the vehicle-mounted display device 100 is in a standby state. At this time, the solar panel 110 is embedded in 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 vehicle-mounted display device 100 is in an operating state. At this time, the solar panel 110 is raised relative to the center console 300, thereby expanding the area receiving external ambient light, which can maximize the utilization of solar energy.

[0040] 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 vehicle-mounted display device 100 is in a first state, the power component 131 controls the bracket component 140 to be lifted relative to the center console 300. When the vehicle-mounted display device 100 is in a second state, the power component 131 controls the bracket component 140 to be embedded in the center console 300.

[0041] In the present application, since the solar panel 110 is mounted 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 mounted on the bracket assembly 140 can also be lifted or embedded relative to the center console 300 along with the bracket assembly 140, thereby preventing the solar panel 110 from being exposed to the external environment for a long time, which is beneficial to extending the service life of the solar panel 110.

[0042] When the in-vehicle display device 100 is in the first state (operating state), the power assembly 131 controls the bracket assembly 140 to rise relative to the center console 300, so that the solar panel 110 rises along with the rise of the bracket assembly 140. The solar panel 110 is exposed from the center console 300 and is completely exposed to the environment inside the vehicle, so that the solar panel 110 can receive more light from the external environment, thereby facilitating the solar panel 110 to convert more light energy into electrical energy, thereby improving the energy storage efficiency of the solar panel 110.

[0043] When the vehicle-mounted display device 100 is in the second state (standby state), the power assembly 131 controls the bracket assembly 140 to be embedded in the center console 300, so that the solar panel 110 is embedded in the center console 300 along with the bracket assembly 140, and only the surface of the solar panel 110 is exposed outside the center console 300. This not only ensures that the solar panel 110 can receive light to a certain extent and convert light energy into electrical energy without affecting the solar panel 110 from supplying power to the vehicle-mounted display device 100; it also effectively prevents collisions or scratches caused by external objects inside the center console 300, thereby extending the service life of the solar panel 110.

[0044] Specifically, the bracket assembly 140 includes a frame 141, a support member 150 and a crossbeam 160. The crossbeam 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 crossbeam 160; one end of the support member 150 is connected to the crossbeam 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 motherboard 133. The electric push rod 132 is connected between the crossbeam 160 and the frame 141, and the control motherboard 133 is installed on the crossbeam 160; the electric push rod 132 is electrically connected to the control motherboard 133, and the control motherboard 133 controls the electric push rod 132 to extend and retract a preset distance along its own axial direction to push the frame 141 to rise relative to the center console 300, or pull the frame 141 to be embedded in the center console 300.

[0045] In this embodiment, the crossbeam 160 is connected to the cavity 310 of the center console 300, so that the crossbeam 160 can provide support for other components in the center console 300. There can be two support members 150, one end of the two support members 150 is respectively connected to the opposite sides of the crossbeam 160, and the other end is rotatably connected to the two ends of the frame 141 through a pin. On the one hand, the support members 150 can support the frame 141 to ensure the stability of the solar panel 110 installed on the frame 141, and on the other hand, it can also enable the frame 141 connected to the support members 150 to rotate. When the control motherboard 133 controls the electric push rod 132 to extend, the electric push rod 132 will push the frame 141 toward the outside of the center console 300. At this time, the frame 141 rotates to one side, driving the solar panel 110 installed on the frame 141 to rotate accordingly, thereby achieving a lifting effect of the solar panel 110 relative to the center console 300, so that the solar panel 110 can receive light over a larger range and improve energy conversion efficiency.

[0046] When the control board 133 controls the electric push rod 132 to retract, the electric push rod 132 pulls the frame 141 toward 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 and re-embed it into the center console 300. The center console 300 protects the solar panel 110 and prevents the solar panel 110 from being exposed to the external environment for a long time, which may cause it to be easily damaged. In other words, the present application realizes the longitudinal rotation and lifting of the solar panel 110 by driving the frame 141 to rotate by the electric push rod 132.

[0047] Furthermore, a slide rail 142 is provided on the frame 141, and 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 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 to a maximum angle relative to the center console 300; 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 be on the same horizontal plane relative to the table surface of the center console 300.

[0048] 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 forms a limit on one end of the electric push rod 132, so that the one end of the electric push rod 132 can only move within the slide rail 142; when the control board 133 controls the electric push rod 132 to extend, the electric push rod 132 will push the frame 141 toward the outside of the center console 300, so that the frame 141 rotates to one side, and during the rotation of the frame 141, the slide rail 142 on the frame 141 will be relative to the electric push rod 132 and the slide rail 142. The connection end of the rail 142 moves, and during the movement of one end of the electric push rod 132 in 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 rack 141 drives the solar panel 110 to rotate to the maximum angle relative to the center console 300. The solar panel 110 can better receive light from the external environment and convert the absorbed light energy into electrical energy, which is beneficial to improving the energy conversion efficiency of the solar panel 110.

[0049] When the control board 133 controls the electric push rod 132 to retract, the electric push rod 132 will pull the frame 141 toward 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 between the electric push rod 132 and the slide rail 142. During the movement of one end of the electric push rod 132 in 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 When it reaches the second end 144, the rack 141 drives the solar panel 110 to be embedded in the center console 300, and makes the outer surface of the solar panel 110 and the table top of the center console 300 to be at the same level. In this way, not only can the solar panel 110 continue to receive light and convert light energy into electrical energy, but it also does not affect the aesthetics of the center console 300. In addition, the center console 300 is used to protect the solar panel 110 and prevent the solar panel 110 from being damaged due to long-term exposure to the external environment.

[0050] In the embodiment of the present application, the electric push rod 132 is extended and retracted to drive the frame 141 to rotate, thereby realizing the rotation and lifting of the solar panel 110. Alternatively, a motor may be directly provided on the frame 141, and the motor may be used to drive the frame 141 to rotate to realize the rotation and lifting of the solar panel 110. The present application only uses the electric push rod 132 as an example, and is not limited to the method of using only the electric push rod 132 to drive the frame 141 to rotate.

[0051] In addition, based on the influence of the weight of the rack 141 itself, in order to ensure that the rack 141 is more stable during rotation, two electric push rods 132 can be set, respectively connected to the two sides of the beam 160, and the two electric push rods 132 are used to push the rack 141 at the same time, further improving the stability of the rotation of the rack 141.

[0052] Furthermore, the bracket assembly 140 also 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 also includes a transmission assembly 180, the transmission assembly 180 is arranged on the frame 141, and the transmission assembly 180 is connected to one end of the first rotating shaft 171 away from the connecting member 170, and the transmission assembly 180 is used to drive the first rotating shaft 171 to rotate.

[0053] In this embodiment, the solar panel 110 is mounted on the connecting member 170 and is fixedly connected to the connecting member 170 via one end of a first rotating shaft 171, and the other end is rotatably connected to a fixing member 172 on the frame 141. The first rotating shaft 171 is driven to rotate by the transmission assembly 180. When the first rotating shaft 171 rotates, it drives 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 achieved, which is conducive to improving the accuracy of the solar panel 110 in finding light.

[0054] 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 shaft 146, the gear set 182 is installed at one 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 is transmitted to the gear set 182, and the gear set 182 drives the first rotating shaft 171 to rotate along its own central axis.

[0055] The first motor 183 may be a reduction motor. In this embodiment, a gear set 182 is mounted on one end of the first rotating shaft 171 connected to the fixing member 172. The gear set 182 is also gear-coupled with a worm 181. One end of the worm 181 is connected to the reduction motor. The worm 181 uses the reduction motor as its power source. The reduction motor drives the worm 181 to rotate. The worm 181 transmits power to the gear set 182. The gear set 182 drives the first rotating shaft 171 to rotate along its central axis, thereby driving the solar panel 110 to rotate. This allows a single reduction motor to drive the solar panel 110 to rotate synchronously along its own rotating axis.

[0056] Of course, there can be multiple solar panels 110 in the present application, and each solar panel 110 is connected to the frame 141 through a connecting member 170, a first rotating shaft 171 and a fixing member 172. The first rotating shaft 171 connected to each solar panel 110 is installed with a gear set 182, and multiple gear sets 182 are simultaneously connected to the worm 181. The worm 181 uses a reduction motor as a power source to simultaneously drive multiple gear sets 182. The multiple gear sets 182 drive the solar panels 110 connected to their respective first rotating shafts 171 to rotate, thereby realizing a single reduction motor driving multiple solar panels 110 to rotate synchronously along their own rotating shafts; since the driving principle is the same as the above scheme, the scheme of simultaneously driving multiple solar panels 110 with one more worm 181 through multiple gear sets 182 will not be repeated.

[0057] The plurality of solar cell panels 110 may be arranged at equal intervals along the axial direction of the rack 141 , and the specific installation positions are based on the rack 141 achieving overall gravity balance.

[0058] Based on the above content, it can be seen that the light-seeking of the solar panel 110 of the present application is divided into two dimensions, namely longitudinal and lateral. 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 lateral rotation of the solar panel 110 through the worm 181 gear set 182, so that the solar panel 110 can be adjusted to any position and any angle, which is beneficial for the solar panel 110 to automatically seek light according to the actual direction of light exposure.

[0059] Figure 5 This is a schematic diagram of a second embodiment of the vehicle-mounted display device of the present application, as shown in FIG. Figure 5As shown, the vehicle 10 includes a vehicle-mounted battery 400, and the vehicle-mounted 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 and is used to detect the power level of the solar panel 110; the control module 600 is electrically connected to the solar panel 110, the display 120 and the vehicle-mounted battery 400, and 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 level of the solar panel 110 is in a 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 level of the solar panel 110 is in a second power state, the control module 600 controls the solar panel 110 to supply power to the vehicle-mounted battery 400.

[0060] This embodiment differs from the previous embodiment in that the power supply method of the solar panel 110 is further improved. The detection module 500 monitors the power status of the solar panel 110 in real time and transmits the information to the control module 600, thereby realizing the function of automatically switching the power supply circuit according to the power status of the solar panel 110. The first power status can be understood as a state when the power level is higher than 20%, and the second power status can be understood as a state when the power level is lower than 20%. The specific power status can be set by the user. This application only uses the power supply switching when the power level is higher or lower than 20% as an example. The specific working principle is as follows:

[0061] When the detection module 500 detects that the power level of the solar panel 110 is in the first power state (when the power level is greater than 20%), the detection module 500 transmits a detection signal to the control module 600, and the control module 600 supplies the power of the solar panel 110 to the vehicle-mounted display device 100 to ensure the normal operation of the vehicle-mounted display device 100.

[0062] When the detection module 500 detects that the solar panel 110 is in the second power state (the power level is less than 20%), the detection module 500 transmits a detection signal to the control module 600. The control module 600 switches the solar panel 110 to charge the vehicle battery 400 to prevent the battery from running low, thereby maximizing the utilization of the electricity generated by the solar panel 110.

[0063] That is, this embodiment distributes the electric energy generated by the solar panel 110 through the control module 600, thereby avoiding waste of electric energy; when the power is sufficient, the power is firstly met to meet the needs of the vehicle display device 100, and when the power is relatively low, the electric energy is stored in the vehicle battery 400 for subsequent use by other equipment of the vehicle 10 or for power supply under no-light conditions, thereby improving the energy utilization efficiency of the entire vehicle 10 system.

[0064] Figure 6This is a schematic diagram of an embodiment of the vehicle of the present application, as shown in FIG. Figure 6 As shown, the embodiment of the present application further discloses a vehicle 10, including a vehicle body 200. The vehicle 10 also includes the above-mentioned vehicle-mounted display device 100, which is connected to the vehicle body 200. The vehicle-mounted display device 100 is used to display driving information or other visual information in the vehicle body 200, thereby enriching the driving experience.

[0065] Generally, the on-board display device 100 carried by the vehicle 10 has a solar panel 110 for supplying power to the display 120 and is disposed on the top of the vehicle body 200 . Long-term exposure to the external environment may easily damage the solar panel 110 .

[0066] Based on the above problems, the present application improves the on-board display device 100 in the vehicle 10. The solar panel 110 for powering the display 120 of the on-board display device 100 is installed in the center console 300 of the vehicle 10 and connected to the solar panel 110 through a lifting system 130. When the on-board display device 100 is in a 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. Light from the external environment that shines into the vehicle body 200 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; and when the on-board display device 100 is in a second state, the lifting system 130 controls the solar panel 110 to be embedded in the center console 300, so that the solar panel 110 is protected by the center console 300, effectively preventing the solar panel 110 from being damaged by external environmental factors. This improves the problem that the solar cell panel 110 of the vehicle-mounted display device 100 is easily damaged due to long-term exposure to the outside of the vehicle body 200 , thereby improving the quality of the vehicle 10 .

[0067] Figure 7 This is a step diagram of the first embodiment of the control method of the vehicle-mounted display device of the present application; Figure 7 As shown, the embodiment of the present application further discloses a control method of the vehicle-mounted display device 100, which is used to control the above-mentioned vehicle-mounted display device 100, including the steps of:

[0068] S1: Get current time information;

[0069] S2: Determine whether the current time information is within the first time interval. If so, control the vehicle-mounted display device 100 to be in the running state; if not, control the vehicle-mounted display device 100 to be in the standby state;

[0070] S3: Detecting the power status of the vehicle 10;

[0071] S4: When it is detected that the power state of the vehicle 10 is in the first power state, the solar panel 110 of the vehicle-mounted display device 100 is controlled to be hidden in the center console 300;

[0072] S5: When it is detected that the power state of the vehicle 10 is in the second power state, the solar panel 110 of the vehicle-mounted display device 100 is controlled to be raised to the working position;

[0073] When it is detected that the power state of the vehicle 10 is in the second power state, light information is detected, and the position of the solar cell panel 110 is adjusted according to the acquired light information.

[0074] In this embodiment, a main control program may be built into the display 120 of the vehicle-mounted display device 100. The built-in main control program may be written using, for example, a single-chip microcomputer, a programmable logic controller, a field-programmable gate array (FPGA), or other devices that can be written according to logic. The main control program may be used to call a clock function to obtain current time information. The built-in logic-edited main control program in the display 120 is a conventional method in the art and will not be elaborated in detail in this application.

[0075] Among them, the first time interval in this application can be 6:00 to 19:00, or it can be other time intervals set by the user; in this embodiment, only the first time interval of 6:00 to 19:00 is used as an example.

[0076] When the detected current time information shows that it is within the time range of 6:00 to 19:00, the main control program built into the vehicle-mounted display device 100 controls the vehicle-mounted display device 100 to turn on. At this time, the solar panel 110 connected to the display 120 is in an operating state, and can collect light from the external environment, thereby converting light energy into electrical energy and storing it. Since the vehicle 10 is generally not in use during this time period, the process of collecting and storing energy from the external ambient light when the vehicle 10 is parked outdoors does not affect the driver's operation and driving, thereby not affecting the driver's driving experience. It can also prevent the solar panel 110 from consuming energy while storing energy, which is conducive to improving the energy storage efficiency of the solar panel 110.

[0077] When the detected current time information is not within the time range of 6:00 to 19:00, the vehicle-mounted display device 100 only turns on the clock function, and all other functions are 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 vehicle-mounted display device 100 enters the sleep standby mode, thereby reducing the energy consumption of the vehicle-mounted display device 100.

[0078] In addition, a general vehicle 10 has a corresponding control system, and the control system is connected to the vehicle-mounted display device 100. Therefore, the vehicle 10's own control system can also be used to control whether the vehicle-mounted display device 100 is in operation or standby state by detecting vehicle 10 information; and controlling the vehicle-mounted display device 100 to operate or standby, as well as turning on or off some functions of the vehicle-mounted display device 100 through the vehicle 10's own control system are conventional means in this field, and this application will not go into details one by one.

[0079] Furthermore, by detecting the power status of the vehicle 10 through the control system of the vehicle 10, it can be determined whether the vehicle-mounted display device 100 is in the first state or the second state, thereby controlling the solar panel 110 to be lifted to the working position or embedded in the center console 300; when it is detected that the power status of the vehicle 10 is in the first power state, it can be determined that the vehicle-mounted display device 100 is in the second state, and the solar panel 110 of the vehicle-mounted display device 100 is controlled to be hidden in the center console 300; when it is detected that the power status of the vehicle 10 is in the second power state, it can be determined that the vehicle-mounted display device 100 is in the first state, and the solar panel 110 of the vehicle-mounted display device 100 is controlled to be lifted to the working position.

[0080] The first power state may be understood as a state in which the power of the vehicle 10 is turned on, and the second power state may be understood as a state in which the power of the vehicle 10 is turned off.

[0081] When the vehicle 10 power-on signal is detected, the system determines that the vehicle has entered the driving state. The control system sends a command 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. In the hidden state, it collects light and generates electricity, waiting for the next start-up signal. Since the vehicle 10 is likely to be in use during this period, in order to prevent the solar panel 110 from interfering with the driver during operation, the operation of the on-board display device 100 can be turned off to prevent the solar panel 110 from rising while the vehicle 10 is driving, thereby preventing the solar panel 110 from being blocked or otherwise interfering with the driver. This is beneficial to improving the driver's driving experience while preventing the solar panel 110 of the on-board display device 100 from being exposed to the external environment for a long time, thereby extending the service life of the solar panel 110.

[0082] When a power-off signal of the vehicle 10 is detected, the control system determines that the vehicle 10 has entered a parking state. The control system can send a pulse command 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.

[0083] That is, in the vehicle-mounted display device 100 of the present application, the operating state of the solar panel 110 can be divided into a hidden state and a raised operating state. When a power-on signal of the vehicle 10 is detected, the control system determines that the vehicle 10 enters a driving state, and the solar panel 110 is in a hidden state, that is, the solar panel 110 is in a cavity 310 inside the center console 300. At this time, the solar panel 110 is flatly laid in the center console 300 to convert electrical energy, and other components are not operating to ensure that solar power generation is performed without blocking the driver's line of sight; when a power-off signal of the vehicle 10 is detected, the control system determines that the vehicle 10 enters a 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 the working position to ensure that the solar panel 110 better receives light from the external environment, thereby improving the photoelectric conversion efficiency of the solar panel 110.

[0084] It should be noted that, in this embodiment, the control system of the vehicle 10 itself sends pulse instructions through the motor driver to control the extension and retraction of the electric push rod 132, which is a conventional means in this field. The specific control methods and steps will not be repeated in this application.

[0085] Figure 8 This is a step diagram of the second embodiment of the control method of the vehicle-mounted display device of the present application, as shown in FIG. Figure 8 As 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 be lifted to the working position also includes:

[0086] S51: perform N lifts;

[0087] S52: Each time the solar panel 110 is lifted, it rotates a preset angle;

[0088] Where N is a natural number, and the interval between two adjacent lifts is the residence time.

[0089] This embodiment is different from the previous embodiment in that, in order to achieve better light collection of the solar panel 110, the lifting process of the solar panel 110 is not completed all at once, but is executed in steps, controlling the solar panel 110 to be lifted to the working position step by step, and setting a retention time between two adjacent lifts.

[0090] During the dwell time, an additional light sensor can respond and provide feedback on currently collected light information. The main control program controls the first motor 183 based on the light information collected by the light sensor, thereby raising the solar panel 110 to a preset angle. The specific value of the dwell time is determined by the response time of the light sensor, and the collected light information can be light power.

[0091] Specifically, for example, when the preset lifting angle is 10° each time and N is 4; when it is detected that the power of the vehicle 10 is off, the solar panel 110 is lifted and the solar panel 110 is driven to rotate 10° each time. After 4 executions, the solar panel 110 is rotated a total of 40°.

[0092] A certain dwell time is set between two consecutive rotations to allow 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.

[0093] After solar panel 110 has traversed all set angles, the main control program calculates the collected data to determine the maximum light power and its corresponding position. Subsequently, the main control program sends a pulse command to electric actuator 132 to precisely adjust the position of solar panel 110 to the point where the light power is maximum, thereby achieving optimal solar energy collection efficiency. This embodiment, through precise angle control and data feedback mechanisms, improves the energy collection performance of solar panel 110.

[0094] In addition, the main control program of the present application includes a sun tracking function, that is, using the clock and timing module of the main control program to repeat the above operation once every certain period of time to ensure that the solar panel 110 is located in the best light receiving position to improve the efficiency of solar power generation.
