Description
Display screen module, electronic exterior rearview mirror and vehicle Technical Field
[0001] The present application relates to the field of power electronics technology, and in particular to a display screen module, an electronic exterior rearview mirror, and a vehicle. Background Art
[0002] The vehicle-mounted electronic exterior rearview mirror is a system consisting of an on-board high-definition camera and an on-board display screen. When the user enters the vehicle, the electronic rearview mirror is required to enter a normal working state, which places strict requirements on the real-time image display of the rearview mirror.
[0003] Screens currently used in electronic exterior mirrors typically include liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). LCDs are widely used due to their low cost and wide availability. However, when the liquid crystal material is exposed to low temperatures, its response speed is slow, resulting in ghosting in dynamic images. This poses a safety risk to screen displays in extremely cold outdoor environments.
[0004] Summary of the Invention
[0005] The present application provides a display screen module, an electronic exterior rearview mirror and a vehicle, which can heat the display screen in a low-temperature environment, thereby ensuring the safety of the screen display.
[0006] In a first aspect, the present application provides a display screen module comprising a display screen, a solar energy conversion unit, and a heating unit. The solar energy conversion unit is configured to convert solar energy into electrical energy and output the electrical energy to the heating unit. After receiving the electrical energy, the heating unit can be powered on and generate heat. The heating unit can be thermally connected to the display screen, i.e., the heating unit can transfer heat to the display screen.
[0007] The display screen module provided in this application is provided with a solar energy conversion unit and a heating unit. The solar energy conversion unit can convert solar energy into electrical energy, which can power the heating unit to generate heat. The heat generated by the heating unit can be transferred to the display screen, thereby maintaining the operating temperature of the display screen and ensuring the real-time response of the screen image, thereby ensuring the safety of vehicle driving. In addition, because the solar energy conversion unit of this application can generate electricity by itself, the display screen module in this application does not consume the entire vehicle's electrical energy reserve, thereby saving the vehicle's energy consumption.
[0008] In some possible embodiments, the display screen module of the present application may further include a control unit. The control unit may be connected to the solar energy conversion unit to receive the electrical energy output by the solar energy conversion unit. The control unit may also be connected to the heating unit to output the electrical energy to the heating unit. Furthermore, the control unit may also control whether the heating unit turns on or off. By configuring the control unit to control whether the heating unit turns on or off, it is possible to easily control the heat generated by the heating unit, thereby preventing damage to the display screen due to overheating.
[0009] In some possible implementations, the control unit may include a temperature sensor that can be used to detect the temperature of the display screen. The control unit can then control the heating unit to turn on or off based on the display screen temperature. By providing a temperature sensor, the display screen temperature can be monitored in real time, allowing for timely heating of the display screen to ensure safe display. Furthermore, this can prevent the heating unit from overheating the display screen, potentially damaging it. Furthermore, integrating the temperature sensor with the control unit can improve the integration of the display screen module.
[0010] In some possible implementations, the display module may include a temperature sensor that can detect the temperature of the display. The control unit can then control the heating unit to turn on or off based on the display temperature. Separate design of the temperature sensor and control unit in the display module facilitates maintenance of individual components.
[0011] In some possible embodiments, a display screen may include a cover plate, a liquid crystal display layer, a backlight optical component layer, and a backlight metal component stacked in sequence. A heating unit may be disposed on a side of the backlight metal component facing away from the cover plate, and the heating unit may be thermally connected to the backlight metal component. By using a metal material for the backlight component, heat can be more efficiently transferred to the liquid crystal display layer due to the metal material's excellent thermal conductivity.
[0012] In some possible implementations, the backlight metal component may be connected to the cover plate via a thermally conductive adhesive. Since the thermally conductive adhesive has good thermal conductivity, it can better transfer heat to the cover plate, thereby transferring heat to the liquid crystal display layer through the cover plate.
[0013] In some possible embodiments, the solar energy conversion unit may be connected to the control unit via a first wire, and the control unit may be connected to the heating unit via a second wire. By providing the wires, the electrical energy converted by the solar energy conversion unit can be effectively and stably transmitted to the control unit, and the electrical energy can also be effectively and stably used to power the heating unit.
[0014] In some possible implementations, an energy storage unit may be provided, connected to the control unit and used to store excess electrical energy. When the vehicle is in a dark environment, the energy storage unit can transfer electrical energy to the control unit, allowing the control unit to power the heating unit and ensure normal operation of the display module.
[0015] In some possible implementation schemes, the power storage unit may be connected to the control unit via a third wire, so that electric energy can be effectively and stably transmitted between the power storage unit and the control unit.
[0016] In some possible implementations, the heating unit may be a heating wire or a heating plate. Since the heating wire or the heating plate has a simple structure and low cost, it can not only achieve the heating function but also save costs.
[0017] In a second aspect, the present application provides an electronic exterior rearview mirror, which may include an image capture device and a display screen module as described in any possible embodiment of the first aspect. The image capture device may be connected to a display screen of the display screen module, thereby transmitting the captured image to the display screen for display on the display screen.
[0018] The electronic exterior rearview mirror in this application can automatically heat the display screen in cold environments to maintain the operating temperature of the display screen and ensure the real-time response of the screen image.
[0019] In a third aspect, the present application provides a vehicle comprising a vehicle body and the electronic exterior rearview mirror as described in the second aspect, wherein the electronic exterior rearview mirror can be arranged on the vehicle body.
[0020] The vehicle provided in this application can improve the driving safety performance of the vehicle because the electronic exterior rearview mirror can maintain the operating temperature of the display screen in real time, ensuring the real-time response of the screen image.
[0021] In some possible implementations, the display module can be located inside the vehicle body. Alternatively, the display screen, heating unit, and control unit within the display module can be embedded within the vehicle body, while the solar energy conversion unit can be located on the roof, front pillar, or windshield. By designing the display module structure, it can meet the requirements of different vehicle interior structures, providing greater adaptability.
[0022] In some possible implementations, the vehicle may also include a body control module. If the display screen module is not equipped with a control unit, the body control module is signal-connected to the display screen module to control the heating unit on and off. If the display screen module is equipped with a control unit, the control unit may be integrated into the body control module to improve the integration within the vehicle.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0035] An electronic exterior mirror is a system consisting of an onboard high-definition camera and an onboard display. Currently, two types of screens are used for electronic exterior mirrors: LCDs and organic electro-optical laser displays. LCDs are widely used due to their low cost and availability. However, LCDs can slow down their response in cold environments, causing ghosting in dynamic images. This poses a safety risk when used outdoors in freezing temperatures.
[0036] To address the slow response of LCD screens in low temperatures, the industry currently uses a warm-up method, utilizing the heat generated by the screen itself combined with the car's air conditioning to bring the screen's temperature up to room temperature, thus ensuring adequate performance. Additionally, screen manufacturers are researching heating technologies within the LCD cell to reduce the screen's heating temperature, but this increases the cost of the screen. Furthermore, both of these solutions are time-consuming and power-intensive.
[0037] Based on this, the embodiments of the present application provide a display screen module, an electronic exterior rearview mirror, and a vehicle that can not only heat the display screen in a low-temperature environment to ensure the safety of the screen display, but also solve the problem of time and power consumption. The following will be combined with specific embodiments to describe the above display screen module and vehicle in detail.
[0038] Please refer to Figure 1, which is a schematic diagram of the structure of a vehicle in an embodiment of the present application. Vehicle 1 may include a body 10 and a chassis (not shown). The chassis is equipped with drive wheels 20 and a powertrain (not shown). The powertrain is in transmission connection with the drive wheels 20, thereby providing driving force for vehicle 1 and ensuring the normal operation of vehicle 1. Body 10 is located on the chassis, and there is space inside body 10 so that a user can sit inside body 10 to control the movement of vehicle 1.
[0039] The vehicle 1 may also be provided with a body control module (not shown in the figure), which may be used to control the opening or closing of the electric doors and windows of the vehicle 1, the turning on or off of the lights, and so on.
[0040] Continuing with FIG1 , in this embodiment, vehicle 1 may be equipped with an electronic exterior rearview mirror 100. This electronic exterior rearview mirror 100 can provide a user with a view of the external environment while inside the vehicle, thereby facilitating the user's assessment of external conditions and ensuring safe driving. Specifically, electronic exterior rearview mirror 100 may include a display module 110 and an image capture device 120. Image capture device 120 may be a high-definition camera or other optical device with recording and photographing capabilities. Image capture device 120 may be mounted on the exterior of vehicle body 10, allowing it to capture real-time images or video of the external environment. For example, image capture device 120 may be mounted on the front of vehicle body 10, with its bottom portion substantially flush with the bottom portion of the front window of vehicle 1. Furthermore, the lens of image capture device 120 may be oriented directly toward the rear of vehicle 1, enabling it to capture more images or video of the area behind vehicle 1.
[0041] The image acquisition device 120 can also rotate relative to the vehicle body 10. When the user leaves the vehicle 1, the lens of the image acquisition device 120 can be rotated to face the vehicle body 10, thereby minimizing the risk of damage to the image acquisition device 120 due to external forces.
[0042] Display screen module 110 can be disposed within vehicle body 10, particularly near the driver's seat. Display screen module 110 can be connected to image acquisition device 120. After image acquisition device 120 captures an image or video, it transmits the image or video to display screen module 110, which then displays the image or video, allowing the user to view external conditions in real time through display screen module 110.
[0043] Referring to Figure 2, Figure 2 is a structural schematic diagram of the display screen module 110 in an embodiment of the present application. In this embodiment, the display screen module 110 may include a solar energy conversion unit 111, a control unit 112, a heating unit 113, a display screen 114, and an energy storage unit 115. The solar energy conversion unit 111 can serve as the energy source of the entire display screen module 110, which can be used to receive solar energy and convert solar energy into electrical energy. The solar energy conversion unit 111 can also be connected to the control unit 112 to transfer electrical energy to the control unit 112. Exemplarily, the solar energy conversion unit 111 can be a solar silicon wafer. The control unit 112 can power the heating unit 113 with electrical energy, and the heating unit 113 can generate heat after being powered on. The heating unit 113 can be thermally connected to the display screen 114, that is, the heat generated by the heating unit 113 can be transferred to the display screen 114, thereby increasing the temperature of the display screen 114.
[0044] The power storage unit 115 can be connected to the control unit 112 and can be used to store excess power. When there is no sunlight or the solar energy conversion unit 111 is underpowered, the power storage unit 115 can start to supply power to the heating unit 113 to ensure that the heating unit 113 can generate heat normally.
[0045] In other embodiments, refer to FIG3 , which is another schematic diagram of the structure of the display screen module 110 in an embodiment of the present application. The display screen module 110 may include a solar energy conversion unit 111, a heating unit 113, and a display screen 114. After the solar energy conversion unit 111 converts solar energy into electrical energy, it can directly output the electrical energy to the heating unit 113. When the heating unit is powered on, it can generate heat and transfer the heat to the display screen 114, thereby increasing the temperature of the display screen 114. Based on this, as an implementation scheme, the body control module can also be connected to the display screen module 110 signal and control the heating unit 113 to turn on or off, thereby causing the heating unit to generate or stop generating heat.
[0046] Referring to Figure 4, Figure 4 is a schematic diagram of the position of the display screen module 110 in an embodiment of the present application. Figure 4 can be understood as the driver's perspective. The display screen module 110 in this embodiment can be suspended inside the vehicle body 10. It can be understood that the display screen module 110 can be independently set inside the vehicle body 10. For example, the display screen module 110 can be placed in a structural member position on the back of the vehicle assembly, that is, the display screen module 110 can be placed near the steering wheel 11 and in front of the steering wheel 11. Since the display screen module 110 is set close to the driver's seat, it can be convenient for the user driving the car to view it in real time.
[0047] Referring to Figure 5, Figure 5 is a schematic diagram of a cross-sectional structure of the display screen module 110 in an embodiment of the present application. As previously mentioned, the display screen module 110 can be in a suspended shape. In this case, the solar energy conversion unit 111 and the display screen 114 can be integrated to form a whole. Specifically, the display screen module 110 may include an outer frame 1141, and the interior of the outer frame 1141 has space for accommodating components such as the display screen 114 and the control unit 112. The display screen 114 can be embedded in the interior of the outer frame 1141 from one side of the outer frame 1141, and the solar energy conversion unit 111 can be set on the other side of the outer frame 1141 to improve the integration of the display screen module 110.
[0048] The display screen 114 in this embodiment may be a liquid crystal display. As shown in FIG4 , the display screen module 110 may include a cover plate 1142, a liquid crystal display layer 1143, a backlight optical component layer 1144, and a backlight metal component 1145, which are stacked in sequence. For example, an opening may be provided on one side of the outer frame 1141. The liquid crystal display layer 1143, the backlight optical component layer 1144, and the backlight metal layer may all be located within the outer frame 1141, and the cover plate 1142 may cover the opening. The backlight metal component 1145 may include a bottom plate 11451 and side plates 11452. The bottom plate 11451 is located on the side of the backlight optical component layer 1144 facing away from the liquid crystal display layer 1143. The side plates 11452 may be disposed around the backlight optical component layer 1144 and the liquid crystal display layer 1143 to prevent light from entering the interior of the display screen 114 from the sides. The side panels 11452 can be connected to the cover panel 1142 via the thermally conductive adhesive 1146 , thereby making the overall structure stable.
[0049] It should be noted that the specific structures of the cover plate 1142 , the liquid crystal display layer 1143 and the backlight optical component layer 1144 in this embodiment are similar to those of the existing liquid crystal display screen 114 , and will not be further described in this embodiment.
[0050] The heating unit 113 can be a heating plate or a heating wire. The heating unit 113 can be positioned on the side of the backlight metal member 1145 facing away from the backlight optical component layer 1144. The cross-sectional area of the heating unit 113 can be made as large as possible within a certain range. This increases the contact area between the heating unit 113 and the backlight metal member 1145, thereby enhancing heat conduction. On the one hand, since the backlight metal member 1145 is connected to the cover plate 1142 via thermally conductive adhesive 1146, after the heating unit 113 transfers heat to the backlight metal member 1145, the backlight metal member 1145 can transfer the heat to the cover plate 1142 via the thermally conductive adhesive 1146, and the cover plate 1142 can transfer the heat to the liquid crystal display layer 1143. On the other hand, the backlight metal member 1145 can also transfer heat to the liquid crystal display layer 1143 via the backlight optical component layer 1144, ensuring that the liquid crystal display layer 1143 operates at an appropriate temperature. In addition, since the backlight component is made of metal, which has excellent thermal conductivity, the heat conduction effect of the backlight metal component 1145 can be further enhanced.
[0051] Continuing with Figure 5 , a slot can be provided on the other side of the outer frame 1141, and the solar energy conversion unit 111 can be mounted in the slot, with the solar energy conversion unit 111 exposed to the exterior of the outer frame 1141. In this embodiment, when the display screen module 110 is suspended, the solar energy conversion unit 111 can be positioned directly opposite the vehicle's windshield and / or front window, while the liquid crystal display layer 1143 can face the user. This allows the solar energy conversion unit 111 to receive and convert solar energy into electrical energy when the vehicle is exposed to sunlight.
[0052] The control unit 112 can be disposed within the outer frame 1141, on the side of the heating unit 113 facing away from the backlight metal member 1145. The control unit 112 can include a temperature sensor 1121, a control chip 1122, and a circuit structure 1123. The solar energy conversion unit 111 can be electrically connected to the circuit structure 1123 via a first wire 116, thereby transmitting electrical energy to the circuit structure 1123 via the first wire 116. The circuit structure 1123 can also be electrically connected to the heating unit 113 via a second wire 117, thereby supplying power to the heating unit 113 via the second wire 117.
[0053] The circuit structure 1123 can also be electrically connected to the energy storage unit 115 via the third wire 118, so that the remaining electrical energy can be transmitted to the energy storage unit 115 via the third wire 118 to store the electrical energy. For example, the energy storage unit 115 in this embodiment can be a battery. When there is no external light, such as at night, when the energy storage unit 115 is used to power the heating unit 113, the energy storage unit 115 can transmit the electrical energy to the circuit structure 1123 via the third wire 118, and the circuit structure 1123 then transmits the electrical energy to the heating unit 113 via the second wire 117.
[0054] The power storage unit 115 can be disposed outside the outer frame 1141, which can reduce the overall volume of the display screen module 110 and facilitate its placement inside the vehicle body 10. Alternatively, in other embodiments, the power storage unit 115 can also be disposed inside the outer frame 1141. This embodiment is not limited to this as long as the display screen module 110 can function normally.
[0055] The temperature sensor 1121 can be used to detect the temperature of the liquid crystal display layer 1143 and transmit the temperature information of the liquid crystal display layer 1143 to the control chip 1122. Based on the temperature information of the liquid crystal display layer 1143, the control chip 1122 can determine whether the display screen 114 needs to be heated. When the display screen 114 needs to be heated, the control chip 1122 can control the circuit structure 1123 to supply power to the heating unit 113 via the second wire 117. When the display screen 114 does not need to be heated, the control chip 1122 can control the circuit structure 1123 to stop supplying power to the heating unit 113. It should be understood that when the control chip 1122 determines whether the display screen 114 needs to be heated, it can preset a threshold value between heating and not heating the display screen 114 and compare the actual detected temperature with the threshold value. When the temperature of the liquid crystal display layer 1143 is below the threshold value, the display screen 114 needs to be heated. When the temperature of the liquid crystal display layer 1143 is above the threshold value, the display screen 114 does not need to be heated.
[0056] Furthermore, while the heating unit 113 generates heat to heat the display screen 114, the temperature sensor 1121 can monitor the temperature of the liquid crystal display layer 1143 in real time. When the temperature of the liquid crystal display layer 1143 gradually rises from a low temperature to a suitable temperature and stabilizes, the control chip 1122 can control the circuit structure 1123 to stop supplying power to the heating unit 113 to prevent damage to the display screen 114 due to excessive temperature. At this point, the circuit structure 1123 can also transmit electrical energy to the energy storage unit 115 via the third wire 118.
[0057] It should be noted that in this embodiment, integrating the temperature sensor 1121 into the control unit 112 can improve the integration of the display screen module 110 and help reduce the size of the display screen module 110, thereby reducing costs. In other embodiments, the temperature sensor 1121 can also be designed separately from the control unit 112, that is, the temperature sensor 1121 and the control unit 112 are independent of each other and work in conjunction with each other.
[0058] 4 shows the control unit 112 disposed inside the outer frame 1141. In other embodiments, when the control unit 112 is disposed outside the outer frame 1141, the control unit 112 may be integrated into the body control module to improve the integration inside the vehicle.
[0059] Referring to Figure 6 , which illustrates another alternative positional diagram of the display screen module 110 in an embodiment of the present application, Figure 5 can be understood as representing the perspective of a user looking outward from the front window while inside the vehicle body 10. In this embodiment, a portion of the display screen module 110 may be embedded within the vehicle body 10. For example, a portion of the display screen module 110 may be embedded within the front door, thereby conserving space within the vehicle body 10.
[0060] Referring to Figures 6 and 7 , Figure 7 is another schematic cross-sectional view of the display screen module 110 according to an embodiment of the present application. The display screen module 110 according to this embodiment includes a cover plate 1142, a liquid crystal display layer 1143, a backlight optical component layer 1144, and a backlight metal member 1145 stacked in sequence. The heating unit 113 is disposed on the side of the backlight metal member 1145 facing away from the backlight optical component layer 1144. The control unit 112 is disposed within the outer frame 1141 and is located on the side of the heating unit 113 facing away from the backlight metal member 1145. The solar energy conversion unit 111 is located outside the outer frame 1141 and is electrically connected to the circuit structure 1123 in the control unit 112 via a first conductive wire 116.
[0061] When the solar energy conversion unit 111 is positioned outside the outer frame 1141, refer to Figure 8, which is a schematic front view of a vehicle according to an embodiment of the present application. For example, the solar energy conversion unit 111 can be positioned on the roof of the vehicle body 10, as shown at position A in Figure 8. Alternatively, the solar energy conversion unit 111 can be positioned on the front pillar of the vehicle body 10, as shown at position B in Figure 8. Alternatively, the solar energy conversion unit 111 can be positioned on the windshield of the vehicle body 10, as shown at position C in Figure 8. It should be noted that the solar energy conversion unit 111 is positioned inside the vehicle body 10. When positioned on the roof, it can be in close contact with the inner wall of the roof and positioned to receive sunlight. Similarly, when positioned on the front pillar or windshield, the solar energy conversion unit 111 can be positioned in close contact with the inner wall of the front pillar or the inner wall of the windshield to facilitate sunlight reception. Furthermore, when positioned on the windshield, the solar energy conversion unit 111 can be positioned in an area with black ink to avoid obstructing the user's field of vision.
[0062] Of course, the solar energy conversion unit 111 can also be installed in other parts of the vehicle body 10, which will not be illustrated in this embodiment. It should be noted that when the solar energy conversion unit 111 is installed, it should not affect the normal use of the vehicle.
[0063] In addition, in this embodiment, the power storage unit 115 may also be disposed outside the outer frame 1141 , so as to save the internal space of the outer frame 1141 and reduce the volume of the outer frame 1141 .
[0064] It should be understood that the display screen module 110 in the embodiment of the present application is not only applicable to the electronic exterior rearview mirror of the vehicle, but can also be applied to other display devices that require heating of the display screen, and this embodiment does not limit this.
[0065] The display screen module, electronic exterior rearview mirror, and vehicle described in this application utilize a solar energy conversion unit and a heating unit. In low-temperature environments, the solar energy converted by the solar energy conversion unit can power the heating unit, allowing the heating unit to heat the display screen. This increased display temperature eliminates driving risks associated with slow display response at low temperatures and reduces the time it takes to warm up the vehicle in severe cold conditions. Furthermore, the system does not actively consume the vehicle's power, eliminating the reliance of screen heating on the vehicle's battery performance.
[0066] Obviously, those skilled in the art may make various modifications and variations to this application without departing from the scope of protection of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
