Description

[Technical Field]

[0001] The present invention relates to the field of power electronics technology, and in particular to a display module, an electronic outer rearview mirror, and a vehicle. [Background technology]

[0002] The on-board electronic outer rearview mirror is a system that includes an on-board high-resolution camera and an on-board display. When a user enters the vehicle, the electronic rearview mirror is required to enter a normal operating state, which imposes strict requirements on the real-time performance of the rearview mirror's image display.

[0003] Currently, the screens used in electronic outer rearview mirrors are typically liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays. Liquid crystal displays are widely used due to their advantages such as low cost and high availability. However, when the temperature of the liquid crystal material is low, the response time is slow, which can cause motion blur in moving images. This poses a safety risk to the screen display in extremely cold outdoor scenarios. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides a display module, an electronic outer rearview mirror, and a vehicle, in which the display can be heated in a low-temperature environment, ensuring the safety of the screen display. [Means for solving the problem]

[0005] According to a first aspect, the present application provides a display module including a display, a solar energy conversion unit, and a heating unit. The solar energy conversion unit may be 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 may be thermally conductively connected to the display. In other words, the heating unit can transfer heat to the display.

[0006] The display module provided herein includes a solar energy conversion unit and a heating unit. The solar energy conversion unit can convert solar energy into electrical energy. The electrical energy can power the heating unit, causing the heating unit to generate heat. The heat generated by the heating unit can be transferred to the display, thereby maintaining the operating temperature of the display and maintaining real-time response of the screen image, thereby ensuring the driving safety of the vehicle. In addition, since the solar energy conversion unit can generate power by itself, the display module does not need to consume the stored electrical energy of the entire vehicle, thereby reducing the energy consumption of the vehicle.

[0007] In some possible implementations, the display module in the present application may further include a control unit. The control unit may be connected to the solar energy conversion unit and receive electrical energy output by the solar energy conversion unit. The control unit may be further connected to the heating unit and output electrical energy to the heating unit. The control unit may also further control the on / off of the heating unit. The control unit is arranged to control the on / off of the heating unit, so that the heat generated by the heating unit can be easily controlled and the display is prevented from being damaged by overheating.

[0008] In some possible implementations, the control unit may include a temperature sensor. The temperature sensor may be configured to detect the temperature of the display. The control unit may control the on / off of the heating unit based on the temperature of the display. The temperature sensor may be installed to detect the temperature of the display in real time, allowing the display to be heated in a timely manner to ensure the safety of the screen display. The heating unit may also be prevented from overheating the display, preventing damage to the display. Furthermore, integrating the temperature sensor with the control unit may help improve the integration of the display module.

[0009] In some possible implementations, the display module may include a temperature sensor. The temperature sensor may be configured to detect the temperature of the display. The control unit may control the heating unit to be turned on or off based on the temperature of the display. The temperature sensor and the control unit of the display module may be designed separately, which may facilitate maintenance of the individual components.

[0010] In some possible implementations, the display may include a cover plate, a liquid crystal display layer, a backlight optical component layer, and a backlight metal member, which are sequentially stacked. A heating unit may be disposed on the backlight metal member away from the cover plate, and the heating unit may be thermally conductively connected to the backlight metal member. The backlight component may be made of a metal material. Metal materials have good thermal conductivity, allowing heat to be more effectively transferred to the liquid crystal display layer.

[0011] In some possible implementations, the backlight metal member may be connected to the cover plate via a thermally conductive adhesive, which has good thermal conductivity, so that heat can be transferred to the cover plate more efficiently, and thus the heat can be transferred to the liquid crystal display layer through the cover plate.

[0012] In some possible implementations, the solar energy conversion unit is connected to the control unit via a first conductor, and the control unit can be connected to the heating unit via a second conductor. By providing the conductor, the electrical energy converted by the solar energy conversion unit can be efficiently and stably transmitted to the control unit, and the electrical energy can also be efficiently and stably supplied to the heating unit.

[0013] In some possible implementations, an electric energy storage unit may be further disposed. The electric energy storage unit may be connected to the control unit and configured to store remaining electric energy. When the vehicle is in a non-illuminated environment, the electric energy storage unit may transmit electric energy to the control unit, so that the control unit may supply power to the heating unit, thereby ensuring normal use of the display module.

[0014] In some possible implementations, the electrical energy storage unit may be connected to the control unit via a third conductor, thereby enabling effective and stable transmission of electrical energy between the electrical energy storage unit and the control unit.

[0015] In some possible implementations, the heating unit may be a heating wire or a heating sheet, which has a simple structure and low cost, and can realize the heating function and reduce costs.

[0016] According to a second aspect, the present application provides an electronic outer rearview mirror. The electronic outer rearview mirror may include an image capture device and a display module according to any one of the possible implementation forms of the first aspect. The image capture device may be connected to a display of the display module, so that a captured image can be transmitted to the display and displayed on the display. [Effects of the Invention]

[0017] The electronic outer rearview mirror of the present invention can automatically heat the display in cold environments, thus maintaining the operating temperature of the display and ensuring real-time response of the screen image.

[0018] According to a third aspect, the present application provides a vehicle including a vehicle body and an electronic outer rearview mirror according to the second aspect. The electronic outer rearview mirror may be disposed on the vehicle body.

[0019] According to the vehicle provided in the present application, the electronic outer rearview mirror can maintain the operating temperature of the display in real time to ensure the real-time response of the screen image, thereby improving the driving safety performance of the vehicle.

[0020] In some possible implementations, the display module may be disposed inside the vehicle body, or the display, heating unit, and control unit of the display module may be integrated into the vehicle body, and the solar energy conversion unit may be disposed on the vehicle roof, front pillar, or windshield of the vehicle body. The structure of the display module is designed to meet different interior structural requirements of the vehicle body and be more adaptable.

[0021] In some possible implementations, the vehicle further includes a body control module. If the control unit is not provided in the display module, the body control module is connected to the display module via a signal and controls the on / off of the heating unit. If the control unit is located in the display module, the control unit may be integrated into the body control module to improve integration within the vehicle. [Brief explanation of the drawings]

[0024] The terms used in the following embodiments are intended merely to describe particular embodiments and are not intended to limit the present application. As used in this specification and the appended claims of this application, the singular forms "one," "a," "the," "the foregoing," "this," and "the one" are intended to include the plural forms "one or more," unless the context clearly dictates otherwise.

[0025] References herein to "an embodiment," "some embodiments," etc., indicate that one or more embodiments of the present application include the particular feature, structure, or characteristic described with reference to the embodiment. Thus, statements such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in other embodiments" appearing in different places herein do not necessarily refer to the same embodiment. Instead, these statements mean "one or more, but not all, of the embodiments," unless specifically emphasized otherwise. The terms "including," "comprising," and "having," and variations thereof, all mean "including, but not limited to," unless specifically emphasized otherwise.

[0026] An electronic exterior rearview mirror is a system that includes an on-board high-resolution camera and an on-board display. Currently, there are two types of screens used in electronic exterior rearview mirrors: liquid crystal displays and organic light-emitting diode displays. Liquid crystal displays are widely used due to their low cost and availability. However, liquid crystal displays have a slow response time in low-temperature environments, and moving images can exhibit motion blur. This poses a safety risk to the screen display in extremely cold outdoor scenarios.

[0027] To address the problem of LCD monitors' slow response in low-temperature environments, the current industry standard is to warm up the vehicle and use the heat generated by the screen itself in conjunction with the vehicle's air conditioning system to heat the screen, thereby bringing it up to room temperature and ensuring its performance. Screen manufacturers are also researching LCD box heating technologies to shorten the time it takes to heat the screen, but this increases the cost of the screen. Furthermore, both of these solutions are time-consuming and power-intensive.

[0028] Based on this, embodiments of the present application provide a display module, an electronic outer rearview mirror, and a vehicle, so that the display can be heated in a low-temperature environment to ensure the safety of the screen display and solve the problems of time and power consumption. Hereinafter, the display module and the vehicle will be described in detail with reference to specific embodiments.

[0029] FIG. 1 is a structural schematic diagram of a vehicle according to an embodiment of the present application. The vehicle 1 may include a vehicle body 10 and a chassis (not shown). The chassis is provided with drive wheels 20 and a powertrain (not shown). The powertrain is connected to the drive wheels 20 via a transmission to provide driving force to the vehicle 1 and ensure that the vehicle 1 can run normally. The vehicle body 10 is located on the chassis, and there is space inside the vehicle body 10, allowing a user to sit on the vehicle body 10 and control the vehicle 1 to move forward.

[0030] A body control module (not shown) may further be provided in the vehicle 1. The body control module may be configured to control the opening and closing of electric doors or windows of the vehicle 1, control the turning on and off of lights, and the like.

[0031] Continuing to refer to FIG. 1 , in this embodiment, the vehicle 1 may be provided with an electronic outer rearview mirror 100. The electronic outer rearview mirror 100 can provide a user with a scene of the external environment while the user is in the vehicle, allowing the user to assess the situation outside the vehicle and continue driving safely. Specifically, the electronic outer rearview mirror 100 may include a display module 110 and an image capture device 120. The image capture device 120 may be a high-resolution camera or other optical device with video recording and photography capabilities. The image capture device 120 may be mounted on the exterior of the vehicle body 10, thereby enabling the image capture device 120 to capture images or videos of the external environment in real time. For example, the image capture device 120 may be disposed in front of the vehicle body 10. The bottom surface of the image capture device 120 may be substantially flush with the bottom surface of the front windshield of the vehicle 1. Furthermore, by having the lens of the image capturing device 120 facing rearward of the vehicle 1, the image capturing device 120 can capture more images or videos of the rear of the vehicle 1.

[0032] The image capture device 120 may further rotate relative to the vehicle body 10. After the user leaves the vehicle 1, the lens of the image capture device 120 can rotate to face the vehicle body 10 to minimize damage to the image capture device 120 under the action of external forces.

[0033] The display module 110 may be disposed inside the vehicle body 10, or the display module 110 may be located near the driving position. The display module 110 may be connected to the image capture device 120. After capturing an image or video, the image capture device 120 may transmit the image or video to the display module 110. The display module 110 can display the image or video, allowing a user to view the external situation in real time through the display module 110.

[0034] FIG. 2 is a diagram illustrating the structure of a display module 110 according to an embodiment of the present application. In this embodiment, the display module 110 includes a solar energy conversion unit 111, a control unit 112, a heating unit 113, a display 114, and an electric energy storage unit 115. The solar energy conversion unit 111 may be used as an energy source for the entire display module 110 and may be configured to receive solar energy and convert the solar energy into electric energy. The solar energy conversion unit 111 is further connected to the control unit 112 and transmits electric energy to the control unit 112. For example, the solar energy conversion unit 111 may be a solar silicon wafer. The control unit 112 may use the electric energy to power the heating unit 113. The heating unit 113 may generate heat after the heating unit 113 is powered on. The heating unit 113 may be thermally conductively connected to the display 114. That is, the heat generated by the heating unit 113 is transferred to the display 114, causing the temperature of the display 114 to increase.

[0035] The electric energy storage unit 115 may be connected to the control unit 112 and configured to store surplus electric energy. When there is no sunlight from outside or the power of the solar energy conversion unit 111 is insufficient, the electric energy storage unit 115 may start supplying power to the heating unit 113 to ensure that the heating unit 113 can generate heat normally.

[0036] 3 is a diagram of another structure of the display module 110 according to an embodiment of the present application. The display module 110 may include a solar energy conversion unit 111, a heating unit 113, and a display 114. The solar energy conversion unit 111 can convert solar energy into electrical energy and then directly output the electrical energy to the heating unit 113. After the heating unit is powered on, the heating unit may generate heat and transfer the heat to the display 114, resulting in an increase in the temperature of the display 114. Based on this, in one implementation, the body control module is further connected to the display module 110 via a signal and can control the heating unit 113 to turn on or off, causing the heating unit to generate heat or stop generating heat.

[0037] FIG. 4 is a diagram illustrating the position of the display module 110 according to an embodiment of the present application. FIG. 4 can be understood as a driver's viewpoint. The display module 110 of this embodiment may have a shape that floats inside the vehicle body 10. It can be understood that the display module 110 may be independently disposed inside the vehicle body 10. For example, the display module 110 may be disposed at a structural member position on the rear of the vehicle assembly. In other words, the display module 110 may be disposed close to the steering wheel 11, or may be located in front of the steering wheel 11. The display module 110 is disposed near the driving position to facilitate real-time viewing by a user driving the vehicle.

[0038] FIG. 5 is a cross-sectional view of a display module 110 according to an embodiment of the present application. As such, the display module 110 may have a floating shape. In this case, the solar energy conversion unit 111 and the display 114 may be integrated to form a whole. Specifically, the display module 110 may include an outer frame 1141. Inside the outer frame 1141, there is a space for accommodating components such as the display 114 and the control unit 112. The display 114 may be integrated into the outer frame 1141 via one side thereof, and the solar energy conversion unit 111 may be disposed on the other side thereof to improve the integration degree of the display module 110.

[0039] The display 114 in this embodiment may be a liquid crystal display. As shown in FIG. 4 , the display module 110 may include a cover plate 1142, a liquid crystal display layer 1143, a backlight optical component layer 1144, and a backlight metal member 1145, which are stacked in series. 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 member may all be located inside the outer frame 1141. The cover plate 1142 may cover the opening. The backlight metal member 1145 includes a bottom plate 11451 and a side plate 11452. The bottom plate 11451 is located on the side of the backlight optical component layer 1144 away from the liquid crystal display layer 1143. The side plate 11452 is 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 114 from the side edges. The side plates 11452 may be connected to the cover plate 1142 via a thermally conductive adhesive 1146, which stabilizes the entire structure.

[0040] It should be noted that the specific structures of the cover plate 1142, the liquid crystal display layer 1143 and the backlight optical components layer 1144 in this embodiment are all similar to those of the conventional liquid crystal display 114. In this embodiment, the description of the structures thereof will be omitted.

[0041] The heating unit 113 may be a heating sheet or a heating wire. The heating unit 113 may be disposed on the side of the backlight metal member 1145 away from the backlight optical component layer 1144. The cross-sectional area of ​​the heating unit 113 may be as large as possible within a certain range. In this manner, the contact area between the heating unit 113 and the backlight metal member 1145 can be increased to enhance the heat conduction effect. In one embodiment, the backlight metal member 1145 is connected to the cover plate 1142 via a thermally conductive adhesive 1146. After the heating unit 113 transfers heat to the backlight metal member 1145, the backlight metal member 1145 can transfer heat to the cover plate 1142 via the thermally conductive adhesive 1146, and the cover plate 1142 can transfer heat to the liquid crystal display layer 1143. In another aspect, the backlight metal member 1145 can further transfer heat to the liquid crystal display layer 1143 through the backlight optical component layer 1144 to ensure that the liquid crystal display layer 1143 operates at an appropriate temperature. In addition, the material of the backlight member is a metal material, which has good thermal conductivity, so that the thermal conductivity effect of the backlight metal member 1145 can be further enhanced.

[0042] Continuing to refer to FIG. 5, a groove is formed on the other side of the outer frame 1141. The solar energy conversion unit 111 may be disposed in the groove, and the solar energy conversion unit 111 is exposed to the outside of the outer frame 1141. In this embodiment, when the display module 110 is installed in a floating manner, the solar energy conversion unit 111 faces the windshield and / or front window of the vehicle, and the liquid crystal display layer 1143 faces the user. In this way, when the vehicle is in an environment where sunlight can be irradiated, the solar energy conversion unit 111 can receive solar energy and then convert the solar energy into electrical energy.

[0043] The control unit 112 may be disposed inside the outer frame 1141 and located on the side of the heating unit 113 away from the backlight metal member 1145. The control unit 112 may include a temperature sensor 1121, a control chip 1122, and a circuit structure 1123. The solar energy conversion unit 111 is electrically connected to the circuit structure 1123 via a first conductive wire 116, and electrical energy is transmitted to the circuit structure 1123 via the first conductive wire 116. The circuit structure 1123 is electrically connected to the heating unit 113 via a second conductive wire 117, and supplies power to the heating unit 113 via the second conductive wire 117.

[0044] The circuit structure 1123 may be further electrically connected to the electric energy storage unit 115 via the third wire 118, so that the remaining electric energy can be transmitted to the electric energy storage unit 115 via the third wire 118 to store the electric energy. For example, the electric energy storage unit 115 in this embodiment may be a battery. When there is no external light, for example at night, when the electric energy storage unit 115 supplies power to the heating unit 113, the electric energy storage unit 115 transmits electric energy to the circuit structure 1123 via the third wire 118, and then the circuit structure 1123 transmits electric energy to the heating unit 113 via the second wire 117.

[0045] The electric energy storage unit 115 may be disposed outside the outer frame 1141. In this way, the overall size of the display module 110 can be reduced, thereby making it possible to easily dispose the electric energy storage unit 115 inside the vehicle body 10. Alternatively, in some other embodiments, the electric energy storage unit 115 may be disposed inside the outer frame 1141, as long as the display module 110 can normally perform the functions of the display module 110. This is not limited in this embodiment.

[0046] The temperature sensor 1121 may be configured 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. The control chip 1122 can determine whether the display 114 needs to be heated based on the temperature information of the liquid crystal display layer 1143. If the display 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 conductive wire 117. If the display 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 114 needs to be heated, a critical value for heating or not heating the display 114 may be preset, and the actually detected temperature is compared with the critical value. If the temperature of the liquid crystal display layer 1143 is lower than the critical value, the display 114 needs to be heated. If the temperature of the liquid crystal display layer 1143 is above the critical value, there is no need to heat the display 114 .

[0047] Furthermore, when the heating unit 113 generates heat to heat the display 114, the temperature sensor 1121 can detect the temperature of the liquid crystal display layer 1143 in real time. After the temperature of the liquid crystal display layer 1143 gradually rises from a low temperature to an appropriate temperature and stabilizes, the control chip 1122 can further control the circuit structure 1123 to stop supplying power to the heating unit 113 to prevent the display 114 from being damaged by an excessively high temperature. In this case, the circuit structure 1123 can further transmit electrical energy to the electrical energy storage unit 115 via the third conducting wire 118.

[0048] It should be noted that in this embodiment, the temperature sensor 1121 is integrated into the control unit 112, which can improve the integration degree of the display module 110, reduce the size of the display module 110, and reduce the cost. In some other embodiments, the temperature sensor 1121 and the control unit 112 may be designed separately. That is, the temperature sensor 1121 and the control unit 112 are independent of each other and cooperate with each other.

[0049] 4 is disposed inside the outer frame 1141. In some other embodiments, when the control unit 112 is disposed outside the outer frame 1141, the control unit 112 may be integrated into a vehicle body control module to improve integration within the vehicle.

[0050] 6 is a diagram of another position of the display module 110 according to an embodiment of the present application. FIG. 5 may be understood as a viewpoint from which a user inside the vehicle body 10 looks outside through the front window. In this embodiment, a portion of the display module 110 may be incorporated into the vehicle body 10. For example, a portion of the display module 110 may be incorporated into the front door of the vehicle. This can save space inside the vehicle body 10.

[0051] Please refer to Figures 6 and 7. Figure 7 is another cross-sectional view of a display module 110 according to an embodiment of the present application. The display module 110 of 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, which are stacked in series. The heating unit 113 is disposed on the side of the backlight metal member 1145 away from the backlight optical component layer 1144. The control unit 112 is disposed inside the outer frame 1141 and is located on the side of the heating unit 113 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.

[0052] When the solar energy conversion unit 111 is disposed outside the outer frame 1141, please refer to FIG. 8 . FIG. 8 is a front view of a vehicle according to an embodiment of the present application. For example, the solar energy conversion unit 111 may be disposed on the vehicle roof of the vehicle body 10, i.e., may be located at position A in FIG. 8 . Alternatively, the solar energy conversion unit 111 may be further disposed on the front pillar of the vehicle body 10, i.e., may be located at position B in FIG. 8 . Alternatively, the solar energy conversion unit 111 may be further disposed on the windshield of the vehicle body 10, i.e., may be located at position C in FIG. 8 . Note that the solar energy conversion unit 111 is located inside the vehicle body 10. When the solar energy conversion unit 111 is disposed on the vehicle roof, the solar energy conversion unit 111 may be attached in close contact with the inner wall of the vehicle roof and positioned so that it can be irradiated with sunlight. Similarly, when the solar energy conversion unit 111 is disposed on the front pillar or windshield, the solar energy conversion unit 111 is also attached in close contact with the inner wall of the front pillar or windshield, so that it can easily receive sunlight. Also, when the solar energy conversion unit 111 is disposed on the windshield, the solar energy conversion unit 111 may be disposed in the black ink area, so that the user's field of vision is not affected.

[0053] Of course, the solar energy conversion unit 111 may be disposed in other parts of the vehicle body 10. This embodiment does not use examples to describe other parts one by one. However, installing the solar energy conversion unit 111 will not affect the normal use of the vehicle.

[0054] In addition, in this embodiment, the electric energy storage unit 115 may be provided outside the outer frame 1141, saving space inside the outer frame 1141 and reducing the size of the outer frame 1141.

[0055] It should be understood that the display module 110 in this embodiment of the present application is not only applicable to the electronic outer rearview mirror of a vehicle, but also applicable to other display devices that require a heated display, which is not limited in this embodiment.

[0056] The display module, electronic outer rearview mirror, and vehicle of the present application are provided with a solar energy conversion unit and a heating unit. In low-temperature environments, the heating unit can be powered by using the electrical energy converted by the solar energy conversion unit, which then heats the display. By increasing the display temperature, driving risks caused by slow display response in low temperatures can be eliminated and the vehicle warm-up time in extremely cold environments can be shortened. Furthermore, since the display module does not actively consume power from the entire vehicle, the dependence of screen heating on the vehicle's overall battery performance can be eliminated.

[0057] It is obvious that those skilled in the art can make various modifications and variations to this application without departing from the scope of protection of this application. Thus, this application intends to cover these modifications and variations of this application, provided that they fall within the scope of the following claims and their equivalent technologies.
