Description

Technical Field

[0001] The present application relates to the field of display technology and the field of intelligent vehicle driving technology, and more specifically, to a display device and a vehicle. Background Art

[0002] Automobiles have become an indispensable means of transportation in people's daily lives. With the intelligent development of automobiles, people's application requirements for automobiles have been upgraded from simple means of transportation to living spaces with certain information acquisition and entertainment enjoyment. Among them, in-vehicle display technology has become a popular research direction. By installing an in-vehicle display device in a vehicle, passengers in the vehicle can obtain information or perform activities such as watching movies through the in-vehicle display device, thereby providing an intelligent application scenario for the cockpit space.

[0003] Generally speaking, in order to endow the display device with certain collision safety performance, a metal shell is used to protect the display device. However, at any link from the production to the use of the display device, the metal shell with strong electrical conductivity is extremely likely to generate instantaneous high voltage with the external environment, causing the electronic components on the printed circuit board (PCB) near the metal shell to be broken down, resulting in the inability of the PCB to work properly and causing some functions of the display device to be unusable. Therefore, how to balance the collision performance of the display device while avoiding the damage of the PCB caused by static electricity to the display device is a problem that needs to be solved. Summary of the Invention

[0004] The present application provides a display device and a vehicle. The display device provided by the present application can provide electrostatic protection for the PCB in the display device, so that the display device of the present application can not only have anti-collision performance but also meet the requirements of electromagnetic compatibility (EMC).

[0005] In a first aspect, an embodiment of the present application provides a display device. The display device includes: a window unit, a first metal housing, an isolation component, a first module, and a printed circuit board PCB. The first metal housing is fixedly connected to the outer surface of the window unit, and the PCB is fixedly connected to the second surface of the isolation component. Among them, an opening is provided on the outer surface of the first metal housing, and the isolation component is arranged inside the opening. The first surface of the isolation component is fixedly connected to the inner surface of the first metal housing. The first module is arranged on the first surface of the isolation component at the opening. The isolation component is used to provide electrostatic protection for the PCB. The first module and the PCB implement one or more functions of the display device. The window unit is used for a human eye to view an image generated by the display device through the outer surface of the window unit.

[0006] Based on the above solution, the display device provided in this application achieves physical isolation between the first metal housing and the PCB through the isolation component, thereby achieving the electrostatic protection effect on the PCB.

[0007] Combined with the first aspect, in some implementation manners of the first aspect, the display device further includes an image generation unit, an image amplification unit, and a second metal housing. One end of the second metal housing is connected to the upper edge of the window unit, and the other end of the second metal housing is connected to the lower edge of the window unit, so that the second metal housing and the window unit form a closed cavity. The image generation unit and the image amplification unit are disposed in the cavity. Among them, the image generation unit is configured to emit image light to the window unit, and the image light is used to generate the image; the window unit is further configured to reflect the image light from the image generation unit to the image amplification unit on the inner surface of the window unit, and transmit the image light from the image amplification unit to the human eye through the outer surface of the window unit; the image amplification unit is configured to reflect the image light from the window unit to the window unit.

[0008] Based on the above solution, the protection of the internal optical components of the display device is achieved through the metal housing, thereby further improving the anti-collision performance of the display device.

[0009] Combined with the first aspect, in some implementation manners of the first aspect, the first surface of the isolation component is fixedly connected to the inner surface of the first metal housing, including: the first surface of the isolation component is fixedly connected to the inner surface of the first metal housing through a plurality of screws.

[0010] Fixing the isolation component and the first metal housing through screws enhances the stability of the connection between the isolation component and the first metal housing, and at the same time makes the isolation component and the first metal housing detachable. For example, when the first metal housing is damaged or worn, the isolation component can still be used with a new first metal housing, extending the service life.

[0011] Combined with the first aspect, in some implementation manners of the first aspect, the PCB is fixedly connected to the second surface of the isolation component, including: the PCB is fixedly connected to the second surface of the isolation component through a plurality of elastic buckles.

[0012] Fixing the PCB and the isolation component through buckles enables the flexible disassembly between the PCB and the isolation component, facilitating replacement and installation.

[0013] In combination with the first aspect, in some implementations of the first aspect, a plurality of convex portions are provided on the second surface of the isolation component, and the plurality of convex portions are located between the plurality of screws and the PCB.

[0014] Providing a plurality of convex portions on the second surface of the isolation component can further enhance the electrostatic isolation between the screws and the PCB, thereby further improving the performance of the display device.

[0015] In combination with the first aspect, in some implementations of the first aspect, the PCB is embedded inside the isolation component, and the isolation component is further used to isolate the plurality of screws from the PCB. In combination with the first aspect, in some implementations of the first aspect, the first module is a button module, and the button module includes physical buttons and sensors. When the button module works, the physical buttons are connected to the PCB through the sensors.

[0016] In combination with the first aspect, in some implementations of the first aspect, the surface of the button module is flush with the surface of the first metal housing.

[0017] By setting the surface of the button module to be flush with the surface of the first metal housing, it is possible to improve the aesthetic appearance of the display device while preventing external dust from entering the interior of the display device from the edge of the first module, thereby achieving the effect of protecting the display device.

[0018] In combination with the first aspect, in some implementations of the first aspect, the material of the isolation component is plastic.

[0019] Using common plastic as the material of the isolation component can save costs.

[0020] In a second aspect, an embodiment of the present application provides a cockpit system, and the cockpit system includes the display device provided by the first aspect and any implementation of the first aspect.

[0021] In a third aspect, an embodiment of the present application provides a vehicle, including the display device provided by the first aspect and any implementation of the first aspect.

[0022] The beneficial effects brought by the above second aspect and third aspect can specifically refer to the description of the beneficial effects in the first aspect, and will not be elaborated here. Description of the Drawings

[0033] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0034] For ease of understanding of the embodiments of the present application, the following explanations are made.

[0035] First, for the textual descriptions or terms in the accompanying drawings in the embodiments of the present application shown below, terms such as "first", "second", etc. and various numerical numbers are only for convenience of description for differentiation, and are not used to limit the scope of the embodiments of the present application. For example, the first metal housing and the second metal housing are used to distinguish different metal housings, etc.

[0036] Second, the terms "include" and "have" and any variations thereof in the embodiments of the present application shown below are intended to cover non-exclusive inclusion. For example, a system, product or device including a series of units does not necessarily have to be limited to those units clearly listed, but may include other units not clearly listed or inherent to these products or devices.

[0037] Third, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to represent examples, illustrations or explanations. Embodiments or design solutions described as "exemplarily" or "for example" should not be construed as being more preferred or having more advantages than other embodiments or design solutions. The use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner for easy understanding.

[0038] Fourth, in the embodiments of the present application, image light refers to light carrying an image (or image information), which is used to generate an image and can also be called imaging light, etc.

[0039] Fifth, in the drawings of the present application, for the convenience of illustration, the thickness, size and shape of each optical element have been slightly exaggerated. Specifically, the shapes of the optical elements shown in the drawings are shown by way of examples, and the drawings are only examples and not drawn strictly to scale.

[0040] Sixth, unless otherwise defined, all terms used in the present application (including technical terms and scientific terms) have the same meaning as commonly understood by those of ordinary skill in the art to which the present application belongs. It should also be understood that terms (such as those defined in a common dictionary) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0041] With the rapid development of intelligent vehicles, cars play more and more roles in people's lives, and the demand for in-vehicle displays is gradually increasing. For example, providing entertainment services such as games and movies for passengers during long trips. Or, providing a private office display environment for office workers, etc.

[0042] In order to achieve large-size and long-distance in-vehicle display functions, currently, the research focus is on using projection display technology instead of the scheme of directly installing a display screen. Generally speaking, there are multiple optical elements in a projection display system. In order to meet the collision performance requirements of in-vehicle display devices, the projection display system usually uses a metal shell to protect the optical elements in the display system. However, since the metal shell is conductive, it is extremely easy to generate static electricity with the external environment. For example, when a user operates the display device, an instantaneous high voltage of up to 20 KV will be generated at the place where the user touches. This instantaneous voltage will break down the electronic components on the PCB near the metal shell, causing the electronic components to be damaged by electrostatic breakdown and fail, so that the PCB cannot provide certain functions for the display device.

[0043] In view of this, the embodiments of the present application provide a display device that can play an electrostatic protection role for the PCB near the metal shell of the display device.

[0044] Figure 1Schematic diagram of an application scenario of a smart cockpit display system 100 applicable to an embodiment of the present application. Figure 1 As shown, the intelligent cockpit display system 100 includes at least one display device 101 and at least one seat 102. Figure 1 The example is shown in which a display device and a seat are provided, and the display device 101 is provided on the backrest of the seat 102. The display device 101 can generate a long-distance magnified virtual image at a distant image plane through the input of an external video signal (also referred to as a signal source), providing viewers with a large-format, long-distance visual experience, and meeting the needs of users in various application scenarios such as leisure and entertainment, business office, etc.

[0045] It should be noted that the display device 101 can also be installed on the headrest of the seat 102. Alternatively, when the intelligent cockpit display system also includes a dashboard 202, the display device 101 can also be installed on the dashboard 202, such as Figure 2 The cockpit system 200 is shown in FIG. 1 . When the display device 101 is installed on the instrument panel 202, the display device 101 can also be designed to be stored in the instrument panel 202, so that the shape design of the display device 101 is completely coupled with the appearance of the instrument panel 202, so as to achieve the effect of taking into account the beauty of the cockpit system 200. In the system 200, if the user uses the display device 101 or it is detected that the user is in front of the instrument panel 202, the display device 101 can be raised or slid out from the instrument panel, adjusted to a suitable position and angle, and display images for the user to watch.

[0046] It should also be noted that in the embodiment of the present application, the display device 101 may be installed on the backrest of the seat 102, the headrest, or the instrument panel 202 before leaving the factory. Alternatively, it may be installed on the backrest of the seat 102, the headrest, or the instrument panel 202 by modifying the seat 102, the headrest, or the instrument panel 202 after leaving the factory, and the present application does not limit this.

[0047] Understandably, Figure 1 The smart cockpit display system 100 shown is only an example, that is, the smart cockpit display system applicable to the embodiment of the present application is not limited to Figure 1 As shown, it can also include Figure 1 Other systems of the smart cockpit display system 100 shown or Figure 1 This application does not limit other similar systems.

[0048] Figure 3 This is a front view of a schematic diagram of the structure of a display device 300 provided in an embodiment of the present application. The display device 300 can be applied to Figure 1 In the cockpit virtual image display system 100 shown, or applied to Figure 2In the display system 200 shown. As Figure 3 shown, the display device 300 includes a window unit 302, a first metal housing 310, a first module 330, and a second metal housing 320. Among them, the first metal housing 310 is fixedly connected to the outer surface 3021 of the window unit 302.

[0049] Figure 4 This is a schematic cross-sectional view of the display device 300 provided by an embodiment of the present application. As Figure 4 shown, the display device 300 further includes an isolation component 340 and a PCB 350. Among them, an opening is provided on the outer surface 311 of the first metal housing 310, and the isolation component 340 is arranged inside the opening. The first module 330 is arranged on the first surface 341 of the isolation component 340 at the opening. The first surface 341 of the isolation component 340 is fixedly connected to the inner surface 312 of the first metal housing 310, and the second surface 342 of the isolation component 340 is fixedly connected to the surface of the PCB 350. Among them, the isolation component 340 is used for electrostatic protection of the PCB 350 of the first module 330, and the first module 330 and the PCB 350 implement one or more functions of the display device 300.

[0050] It can be understood that the PCB, as the basic structure of an electronic device, connects various electronic components (such as processing chips, memory chips, resistors, capacitors, etc.) together through copper wires and connection holes to form a circuit path, enabling signals and currents to be transmitted inside the electronic device. When there is no isolation component 340 between the PCB 350 and the first metal housing 310, since the first metal housing 310 is very likely to generate an instantaneous high voltage with the external environment (such as user touch, contact with nylon and chemical fiber materials, etc.), the PCB 350 is very likely to be damaged by electrostatic breakdown, and further the functions of each electronic component on the PCB 350 cannot be realized. Therefore, the solution of the present application isolates the PCB 350 from the first metal housing 310 through the isolation component 340, thereby realizing electrostatic protection of the PCB 350.

[0051] Optionally, the material of the isolation component 340 is plastic, such as polycarbonate (PC), or insulating materials such as glass fiber, which is not limited in the present application.

[0052] It should be noted that the first module 330 is connected to the PCB 350 by means of electrical connection or physical connection, etc. At this time, the PCB 350 is both a support component of the first module 330 and a component providing line connection for the first module 330.

[0053] It can be understood that different functions of the display device 300 are jointly realized by the first module 330 and the PCB 350. Among them, the first module 330 can be a module adapted to different application requirements of the display device 300. Exemplarily, the first module 330 can be a push-button module or a scroll-button module for turning on and off the display device 300. Specifically, in Figure 4 the first module 330 is a push-button module, and the push-button module includes a physical button 331 and a sensor 332, where the sensor 332 is electrically connected to the PCB 350. When the user presses the physical button 331, the physical button 331 touches the sensor 332, and the sensor 332 can generate an electrical signal according to the pressing duration, etc., and transmit the electrical signal to the PCB 350, so that after the PCB 350 receives the electrical signal, it lights up or turns off the display device according to the electrical signal. Exemplarily, the first module 330 can also be a camera module for collecting the height information of the human eye. For example, after the camera module collects an image containing the human eye height, it transmits the electrical signal containing the image information to the processing device through the PCB 350, so as to help the processing device adjust the angle or height of the display device 300, so that the user can view the image at a more comfortable angle or height. Exemplarily, the first module 330 can also be a microphone module for collecting the user's voice, converting the voice into an electrical signal, and transmitting the electrical signal to the processing device through the PCB 350, so as to realize the intelligent voice control operation of the display device 300. Exemplarily, the first module 330 can also be a speaker module. When the display device 300 plays a video, the electrical signal carrying the sound information is transmitted to the speaker module through the PCB 350, and the speaker module is controlled to play the sound of the video image in cooperation with the video image, providing the user with a dual enjoyment of hearing and vision. The first module 330 can also be a brightness sensor module for obtaining the ambient light brightness of the display device 300 and converting the brightness into an electrical signal, so as to help the processing device adjust the brightness of the image generated by the display device 300. In addition, the first module 330 can also be a fingerprint recognition module for turning on or off the display device 300 according to the fingerprint information of the user. It can be understood that the first module 330 can also be a module for other functions or applications of the display device 300. At this time, the PCB 350 is used to provide the required circuit connections for other functions of the first module 330, and this application does not make any limitations.

[0054] It can be understood that the functions of the above different types of modules are only examples and do not limit the protection scope of this application. Exemplarily, when the first module 330 is a push-button module, the first module 330 can also be a push-button module for other functions, such as a push-button module for adjusting brightness, adjusting height, or adjusting image contrast, etc. Exemplarily, when the first module 330 is a camera module, it can also be a camera module for collecting cockpit images. Similar explanations are not enumerated one by one here.

[0055] In order to improve the aesthetics of the appearance of the display device 300 and at the same time prevent external dust from entering the interior of the display device, in some embodiments, the surface of the first module 300 can be set to be flush with the surface of the first metal housing 310, that is, the surface of the first module 300 does not protrude or does not protrude too much from the surface of the first metal housing 310. Exemplarily, when the first module 300 is a button module, a push-button module is adopted, and at the same time, the surface of the physical button is set to be a smooth surface flush with the surface of the first metal housing 310, so that the first metal housing 310 and the surface of the physical button are smoothly transitioned and integrated.

[0056] It should be noted that in Figure 4 and Figure 3 only the display device including the first module 330 is taken as an example for illustration. In some other embodiments, the display device 300 may further include at least one other module such as a second module and a third module. These at least one modules may be modules of the same type as the first module 330 but with different functions. Exemplarily, when the first module 330 is a push-button module, if the display device 300 further includes a second module, the second module can also be a push-button module. Although the push-button module is of the same type as the first module 330, the function of the second module is different from that of the first module 330. For example, when the first module 330 is a push-button module for turning on or off the display device 300, the second module can be a push-button module for adjusting brightness, adjusting height, or adjusting image contrast, etc. Or, when the display device 300 further includes at least one other module, the at least one module may be a module of a different type and with a different function from the first module 330. For example, the display device 300 may include a push-button module for turning on and off the display device 300, and may also include a camera module for acquiring images.

[0057] It should also be noted that the position and size of the first module 300 in Figure 3 are only examples and not limitations, that is, the position setting and size design of the first module 300 in the solution of this application are not limited to Figure 3As shown. In other embodiments, the first module 300 can also be disposed on the surface of the second metal housing of the display device 300. The size of the first module 300 can also be designed to be larger for the convenience of user operation. In addition, when the display device 300 includes multiple modules, the positions of the multiple modules can be relatively concentrated to facilitate the common use of the same PCB 350, thereby achieving the purpose of saving the volume of the display device 300 and reducing costs.

[0058] In some embodiments, the first metal housing 310 and the outer surface 3021 of the window unit 302 are fixedly connected by a specific chemical glue. Fixing the first metal housing 310 and the outer surface 3021 of the window unit 302 with chemical glue is simple in operation and low in cost. Alternatively, in other embodiments, the first metal housing 310 and the outer surface 3021 of the window unit 302 are fixedly connected by a plurality of pins, which is not limited in this application. Fixing the first metal housing 310 and the outer surface 3021 of the window unit 302 with a plurality of pins can improve the stability of the connection.

[0059] In some embodiments, the first surface 341 of the isolation component 340 and the inner surface 312 of the first metal housing 310 are fixedly connected by a specific chemical glue. Fixing the isolation component 340 and the first metal housing 310 with chemical glue is simple in operation and low in cost. Alternatively, in other embodiments, the first surface 341 of the isolation component 340 and the inner surface 312 of the first metal housing 310 are fixedly connected by a plurality of screws 510, as Figure 5 shown. Fixing the isolation component 340 and the first metal housing 310 with a plurality of screws 510 improves the stability of the isolation component 340 and the first metal housing 310, and at the same time facilitates the disassembly of the isolation component 340 and the first metal housing 310.

[0060] It should be noted that in the solution of this application, the inner surface 312 of the first metal housing 310 fixedly connected to the window unit 302 is a part of the inner surface 312 of the first metal housing 310, and the inner surface 312 of the first metal housing 310 fixedly connected to the first surface 341 of the isolation component 340 is another part of the inner surface 312 of the first metal housing 310. In other words, the inner surface of the first metal housing 310 fixedly connected to the window unit 302 is different from the inner surface of the first metal housing 310 fixedly connected to the first surface 341.

[0061] In some embodiments, the PCB 350 and the second surface 342 of the isolation component 340 are fixedly connected by a specific chemical glue. Fixing the isolation component 340 and the first metal housing 310 with chemical glue also has the advantage of low cost. Alternatively, in some other embodiments, the PCB 350 and the second surface 342 of the isolation component 340 are fixedly connected by a plurality of elastic buckles 520, as Figure 5 shown. Connecting the second surface 342 of the PCB 350 and the isolation component 340 by a plurality of elastic buckles 520 can make the assembly of the PCB 350 more stable, and at the same time facilitate replacement and disassembly.

[0062] It should be noted that in order to completely isolate the PCB 350 from the first metal housing 310, the isolation component 340 needs to completely surround the PCB 350, that is, the PCB 350 is completely embedded inside the isolation component 340. It should also be understood that when the first surface 341 of the isolation component 340 and the inner surface 312 of the first metal housing 310 are fixedly connected by a plurality of screws 510, the isolation component 340 is also used to isolate the plurality of screws 510 from the PCB 350, that is, the plurality of screws 510 need to be set away from the edge of the PCB 350. In some embodiments, in order to further improve the electrostatic isolation characteristics between the plurality of screws 510 and the PCB 350, a plurality of protrusions may also be provided on the isolation component 340 located between the plurality of screws 510 and the PCB 350, as Figure 6 shown, that is, the plurality of screws 510 and the PCB 350 are further isolated by using the plurality of protrusions provided on the second surface 342 of the isolation component 340.

[0063] It should be noted that the above-described embodiments can be combined and used, and the present application does not limit this. For example, when the first surface 341 of the isolation component 340 and the inner surface 312 of the first metal housing 310 are fixedly connected by a specific chemical glue, the PCB 350 and the second surface 342 of the isolation component 340 can be fixedly connected by a plurality of elastic buckles 520. Another example is that when the first surface 341 of the isolation component 340 and the inner surface 312 of the first metal housing 310 are fixedly connected by a plurality of screws 510, the PCB 350 and the second surface 342 of the isolation component 340 can be fixedly connected by a plurality of elastic buckles 520. At the same time, a plurality of protrusions are provided on the isolation component 340 between the plurality of screws 510 and the PCB 350, etc., which will not be elaborated here.

[0064] Figure 7 This is a possible side structure perspective view of the display device 300 provided by the embodiments of the present application. As Figure 7As shown in the figure, the display device 300 includes an image generation unit 301, a window unit 302, an image magnification unit 303, and a second metal housing 320. Among them, the window unit 302 includes an outer surface 3021 and an inner surface 3022, and a first metal housing 310 is fixed on the outer surface 3021 ( Figure 7 not shown in the figure). One end of the second metal housing 320 is connected to the upper edge of the window unit 302, and the other end of the second metal housing 320 is connected to the lower edge of the window unit 302, so that the second metal housing 320 and the window unit 302 form a closed cavity. The image generation unit 301 and the image magnification unit 303 are arranged in this cavity. At the same time, the inner surface 302 of the window unit 302 is located in this cavity. Specifically, when the display device 300 works (it can be considered as the process of generating an image), the image generation unit 301 emits imaging light to the inner surface 3022 of the window unit 302. After the imaging light is reflected by the inner surface 3022 of the window unit 302, it is transmitted to the surface of the image magnification unit 303. After being reflected by the image magnification unit 303, it reaches the inner surface 3022 of the window unit 302 again, and then passes through the inner surface 3022 of the window unit 302 and exits from the outer surface 3021 of the window unit 302. When the user views the image through the outer surface 3021 of the window unit 302, the image light exiting from the outer surface 3021 of the window unit 302 enters the human eye, so that the human eye can see the virtual image located at the image plane.

[0065] It should be noted that in the solution of this application, the first metal housing 310 can be called the front shell, and the second metal housing 320 can be called the rear shell.
