Description

Technical Field

[0001] This utility model relates to a vehicle-mounted display screen, and more particularly to a vehicle-mounted display screen with an integrated physical switch, as well as a motor vehicle equipped with a vehicle-mounted display screen with an integrated physical switch. Background Technology

[0002] In recent years, the design of center consoles in motor vehicles, especially automobiles, has tended towards larger screens. In order to make the center console more concise and beautiful, and to save space and costs, the functions of physical buttons on the center console have been gradually integrated into the center display screen.

[0003] However, integrating the physical buttons on the center console into the center display screen presents the following problems:

[0004] - When operating the central control display screen via touch, you need to shift your gaze to the central control display screen. In particular, functions such as air conditioning defogging and hazard warning lights may require entering multiple levels of menus to operate, which is inconvenient and may affect driving safety.

[0005] - In bright light or bumpy environments, misoperation is more likely to occur, resulting in a low success rate.

[0006] - In cases where the vehicle's infotainment system freezes, crashes, or restarts, it becomes impossible to operate functions integrated into the central control display via the vehicle's display screen or to accurately determine whether previous operations have taken effect.

[0007] Furthermore, some existing in-vehicle display screens integrate physical switches. However, these physical switches are only used to turn the screen display on and off or to control the volume, and cannot control functions such as air conditioning defrosting or hazard warning lights.

[0008] Furthermore, in existing in-vehicle displays, the physical switches attached to the display cannot function when the display freezes, crashes, or restarts. Utility Model Content

[0009] This invention is made in view of the above-mentioned problems existing in the prior art. Its purpose is to provide an in-vehicle display screen and a motor vehicle with integrated physical switches, so that the functions of the motor vehicle can be controlled through physical switches even when the in-vehicle display screen freezes, crashes, or restarts.

[0010] One embodiment of this invention is an in-vehicle display screen with an integrated physical switch. This in-vehicle display screen is installed in a motor vehicle and includes: an in-vehicle screen having a microcontroller that controls the screen and communicates with a domain controller of the motor vehicle; a physical switch capable of interacting with the in-vehicle screen and having a control circuit board that communicates with the domain controller of the motor vehicle via the screen; and a vibration motor electrically connected to the control circuit board and providing vibration feedback to the user of the physical switch through vibration. The control circuit board of the physical switch is capable of communicating with the domain controller of the motor vehicle independently of the microcontroller of the in-vehicle screen.

[0011] Another aspect of this invention is a motor vehicle equipped with an in-vehicle display screen featuring the aforementioned integrated physical switch.

[0012] According to the above-mentioned technical solution of the utility model, even if the vehicle display screen freezes, crashes, or restarts, the functions of the motor vehicle can still be controlled through a physical switch.

[0013] Furthermore, since the physical switch is integrated into the vehicle display, it can be shipped as a product to the OEM, reducing the OEM's management costs.

[0014] In addition, vibration feedback can be felt when operating the physical switch, so users can know that the corresponding switch has been successfully operated without having to stare at the in-vehicle display screen for a long time. Attached Figure Description

[0050] 1001 Domain Controller Detailed Implementation

[0051] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

[0052] Figure 1 This is a perspective view of the vehicle-mounted display screen 100 with an integrated physical switch according to this embodiment, wherein, Figure 1 (b) is Figure 1 The decomposition diagram of (a). Figure 2 This is a schematic diagram showing the communication paths between the various parts of the vehicle display screen 100 with integrated physical switches in this embodiment and the domain controller 1001 of the motor vehicle.

[0053] like Figure 1 As shown in (a) and (b), the vehicle display 100 with integrated physical switch has a vehicle screen 110 and a physical switch 120. The vehicle screen 110 supplies power to the physical switch 120, for example, via a flexible flat cable, and the vehicle screen 110 is connected to the physical switch 120, for example, via a shielded cable, transmitting control signals of the CAN signal type between the vehicle screen 110 and the physical switch 120.

[0054] In this embodiment, the physical switch 120 is installed on the back cover of the vehicle screen 110 and becomes an integral part of the vehicle screen 110. However, it is not limited to this. For example, the physical switch 120 can also become an integral part of the vehicle screen 110 by plugging or other means. The physical switch 120 can also be installed on a common component with the vehicle screen 110 and become an integral part.

[0055] like Figure 2 As shown, the vehicle-mounted screen 110 has a microcontroller (MCU) 111, which controls the screen and communicates with the vehicle's domain controller 1001 via a communication interface. Specifically, the microcontroller 111 generates graphic signals corresponding to vehicle status data, multimedia data, etc., and displays them on the screen. It also receives user commands input from the screen, executes the commands, or sends them to the vehicle's domain controller 1001. It should be noted that communication with the vehicle's domain controller 1001 can be achieved by transmitting CAN control signals via a CAN bus.

[0056] The physical switch 120 can interact with the vehicle screen 110. For example, when certain functions of the physical switch 120 (such as the air conditioning function) are operated, the corresponding UI will be displayed on the vehicle screen 110.

[0057] Furthermore, the physical switch 120 has a control circuit board 124 that communicates with the domain controller 1001 of the vehicle via the vehicle screen 110. The control circuit board 124 of the physical switch 120 can communicate with the domain controller 1001 of the vehicle independently of the microcontroller 111 of the vehicle screen 120. In addition, the control circuit board 124 of the physical switch 120 can also communicate directly with the microcontroller 111 of the vehicle screen 110.

[0058] Therefore, even if the vehicle screen 110 freezes, crashes, or restarts, the physical switch 120 can still communicate with the vehicle's domain controller 1001, thus enabling control of the vehicle's functions via the physical switch 120. It should be noted that at this time, the signal from the physical switch 120 is not relayed to the vehicle's domain controller 1001 via the microcontroller 111 of the vehicle screen 110, but the microcontroller 111 of the vehicle screen 110 can still monitor the signal from the physical switch 120, etc.

[0059] Furthermore, since the physical switch 120 is integrated into the vehicle display screen, the physical switch 120 and the vehicle display screen 110 can be shipped as a single product to the OEM, which can reduce the OEM's management costs.

[0060] Furthermore, as described above, communication between the physical switch 120 and the vehicle screen 110, as well as communication between the vehicle screen 110 and the vehicle's domain controller 1001, is conducted via the transmission of control signals of the CAN signal type. However, this is not a limitation, and data exchange can also be performed through other communication protocols. The domain controller 1001 can be a traditional vehicle domain controller such as a body domain controller or a cockpit domain controller, or it can be a multi-functional domain controller.

[0061] The above explanation uses vehicle status data and user commands as examples of data interaction content, but the content of data interaction is not limited to this. It can also include air conditioning commands and status information, voice information, multimedia and navigation information, etc.

[0062] Figure 3 This is a schematic diagram showing the composition of the vehicle screen 110.

[0063] In this embodiment, the vehicle screen 110 is formed by bonding a screen module, which is made by bonding a glass cover plate 112, optical adhesive 113, and FOG (FPC OnGlass, a combination of flexible circuit board and glass substrate) 114, to a backlight module 116 provided on a back shell 115 formed by die casting, for example. However, it is not limited to this, and the vehicle screen 110 may also be other types of vehicle screens known in the art.

[0064] Figure 4This is a schematic diagram showing the composition of physical switch 120. Figure 5 This is a perspective view of the touch panel 121 viewed from the opposite direction to the touch panel 121. Figure 6 This is a perspective view of the inner shell 123 as seen from the side of the touch panel 121. Figure 7 This is a perspective view showing the control circuit board 124 and the rear shell 125 as viewed from the middle shell 123 side.

[0065] In this embodiment, the physical switch 120 is a capacitive push-to-vibrate switch, such as... Figure 4 As shown, the device includes a touch panel 121, a bracket 122, a middle shell 123, a control circuit board 124, and a rear shell 125. Furthermore, a vibration motor 126 is provided to provide active feedback to the user. The vibration motor 126 is electrically connected to the control circuit board 124 and provides vibration feedback to the user of the touch panel through vibration. Therefore, when operating the physical switch, the user can feel the vibration feedback, allowing them to know that the corresponding switch has been successfully operated without having to stare at the vehicle's display screen for an extended period.

[0066] The touch panel 121 is formed by attaching a capacitive film to the touch cover and is electrically connected to the control circuit board 124. It can receive the user's pressing or sliding operation on a specific position of the touch panel 121.

[0067] For example, multiple operation patterns 1211 are provided on the surface of the touch panel 121. When the user touches the corresponding operation pattern 1211, the touch panel 121 outputs the corresponding touch operation signal to the control circuit board 124.

[0068] As an operation pattern 1211 set on the surface of the touch panel 121, Figure 8 The diagram shown is an operation pattern for setting the air conditioning function and turning the hazard warning lights on and off, but it is not limited to this. It can also be other operation patterns that can operate the functions of the motor vehicle, and the functions can be customized according to the preferences of the OEM or the user.

[0069] The bracket 122 is attached to the touch panel 121 by a snap-fit, and moves integrally with the touch panel 121 when the touch panel 121 is pressed. In this embodiment, the touch panel 121 and the bracket 122 constitute the "movable part" of the physical switch 120.

[0070] like Figure 5 As shown, multiple openings 1221 are provided on the bracket 122 at positions corresponding to multiple operation patterns 1211. Furthermore, a support column 1222 extending in the opposite direction to the touch panel 121 is provided on the side of the bracket 122 opposite to the touch panel 121.

[0071] like Figure 6As shown, the middle shell 123 has multiple through holes 1231 at positions corresponding to the multiple openings 1221, and a through hole 1232 at a position corresponding to the support column 1222, allowing the support column 1222 of the bracket 122 to pass through. Furthermore, the middle shell 123 has multiple elastic members 1233 on the surface opposite to the bracket 122, which apply an elastic force to the bracket 122 towards the touch panel 121. The elastic members 1233 can be made of rubber, but are not limited to this; they can also be spring components, etc.

[0072] Additionally, the middle shell 123 is provided with a guide portion 1234 to guide the movement of the support 122 toward or away from the middle shell 123. When the touch panel 121 and the support 122 move relative to the middle shell 123, the guide portion 1234 moves within a cutout formed at a corresponding position on the support 122. Furthermore, the middle shell 123 is formed with a limiting portion to restrict the range of movement of the support 122 relative to the middle shell 123. The "guide portion" and "limiting portion" described above are not limited to the solutions shown in the drawings, and other solutions known in the art may also be applied.

[0073] like Figure 7 As shown, a light-emitting part 1241, a pressure-sensitive part 1242, and a display part 1243 are electrically connected to the side of the control circuit board 124 opposite to the middle shell, and a connector 1244 and a speaker (not shown) that can provide acoustic feedback to the user by emitting sound are connected to the opposite side.

[0074] The light-emitting part 1241 is preferably an LED light-emitting element. The light 1241 emitted by the light-emitting part 1241 can be displayed on the touch panel 121 at the position corresponding to the multiple operation patterns 1211 through the through hole 1231 and the opening 1221. By changing the light-emitting state (e.g., switching between on and off, switching between light-emitting color / intensity), optical feedback can be provided to the user.

[0075] The pressure-sensitive unit 1242 detects the pressing force from the support column 1222 when the user presses the touch panel 121 and moves downward against the elastic force of the elastic member 1233. For example, when the pressing force is above a threshold (e.g., 5N), a pressing operation signal is output to the control circuit board 124. It should be noted that the pressure-sensitive unit 1242 may consist of a rubber sleeve and a pressure sensor disposed inside the rubber sleeve, but is not limited to this, and may also be other components capable of detecting the pressing force of the movable part. Moreover, the aforementioned pressing force threshold (5N) can be set to other values ​​as needed.

[0076] The display unit 1243 can display, for example, the air conditioner's set temperature information, and its display content can be displayed at a corresponding position on the touch panel 121. It should be noted that the display unit can also display other information besides the air conditioner's set temperature.

[0077] Connector 1244 is used to control the connection between circuit board 124 and vehicle screen 110. Connectors known in the art can be used.

[0078] The rear shell 125 and the middle shell 123 together constitute the "casing" for housing the control circuit board 124, and the casing and the control circuit board 124 become the "fixed part" relative to the "movable part".

[0079] Figure 8 This is a perspective view of the physical switch 120. A spring clip 127 is also provided on the side of the physical switch 120 for securing it to the die-cast back cover 115 of the vehicle screen 110.

[0080] The operation of the vehicle display screen 100 with integrated physical switches will be explained below.

[0081] For example, when a user touches and presses the operation pattern 1211 of the physical switch 120 with a pressure of at least a threshold (e.g., 5N), the capacitive diaphragm of the touch panel 121 outputs a corresponding touch operation signal to the control circuit board 124. Simultaneously, as the touch panel 121 and the support 122 (movable part) move in the direction of compressing the elastic member 1233, the support column 1222 of the support 122 presses the pressure-sensitive part 1242, which outputs a press operation signal. When both the touch operation signal and the press operation signal are received simultaneously, it is determined that the corresponding operation pattern 1211 has been operated. This causes the vibration motor 126 to operate, and / or changes the illumination state of the corresponding light-emitting part 1241, and / or causes the speaker to emit a prompt sound, thereby providing feedback to the user and making the user aware that the switch has been successfully operated.

[0082] Simultaneously, upon determining that the corresponding operation pattern 1211 has been operated, a CAN control signal, for example, is sent to the vehicle's domain controller, causing the domain controller to execute the corresponding function. At this time, the corresponding UI can be displayed on the in-vehicle screen 110 as needed.

[0083] In addition, the illumination state of the corresponding light-emitting part 1241 can be changed based on information from the domain controller of the motor vehicle or the microcontroller 111 of the vehicle screen 110.

[0084] The technical concept of this utility model is summarized and outlined below, based on the above technical solutions.

[0085] One embodiment of this invention is an in-vehicle display screen with an integrated physical switch. This in-vehicle display screen is installed in a motor vehicle and includes: an in-vehicle screen having a microcontroller that controls the screen and communicates with a domain controller of the motor vehicle; a physical switch capable of interacting with the in-vehicle screen and having a control circuit board that communicates with the domain controller of the motor vehicle via the screen; and a vibration motor electrically connected to the control circuit board and providing vibration feedback to the user of the physical switch through vibration. The control circuit board of the physical switch is capable of communicating with the domain controller of the motor vehicle independently of the microcontroller of the in-vehicle screen.

[0086] According to the above solution, even if the in-vehicle display screen freezes, crashes, or restarts, the functions of the motor vehicle can still be controlled through a physical switch.

[0087] Furthermore, since the physical switch is integrated into the vehicle display, it can be shipped as a product to the OEM, reducing the OEM's management costs.

[0088] In addition, vibration feedback can be felt when operating the physical switch, so users can know that the corresponding switch has been successfully operated without having to stare at the in-vehicle display screen for a long time.

[0089] Based on the above solution, in the vehicle display screen with integrated physical switch of this utility model, the communication between the physical switch and the vehicle screen, and the communication between the vehicle screen and the domain controller of the motor vehicle, are carried out through the transmission of control signals of the CAN signal type.

[0090] It should be noted that, according to this utility model, a CAN signal type control signal is transmitted between the physical switch and the vehicle screen. The signal from the physical switch is sent to the domain controller of the motor vehicle via the CAN bus without being relayed by the microcontroller of the vehicle screen. At the same time, the microcontroller of the vehicle screen can monitor the aforementioned CAN signal.

[0091] Based on the above solution, in the vehicle-mounted display screen with integrated physical switch of this utility model, the physical switch further includes a touch panel, which is electrically connected to the control circuit board and detects the user's touch operation on a specific location of the touch panel. The touch panel is a capacitive touch panel.

[0092] According to the above scheme, using a capacitive touch panel as a physical switch can increase the design freedom of the physical switch, enabling not only pressing operations but also sliding operations, while also having advantages such as long durability, easy cleaning, and aesthetic simplicity.

[0093] Based on the above solution, in the vehicle display screen of the integrated physical switch of this utility model, the physical switch includes a movable part and a fixed part. The movable part is movable and held relative to the fixed part. The movable part includes the touch panel. It is displaced towards the fixed part by being pressed by the touch panel. The fixed part includes a pressure-sensitive part. The pressure-sensitive part is electrically connected to the control circuit board to detect the pressure of the user pressing the movable part.

[0094] The movable part further includes a bracket that moves integrally with the touch panel and contacts the pressure-sensitive part when the touch panel is pressed, and the fixed part further includes the control circuit board and a housing for housing the control circuit board.

[0095] According to the above scheme, the operation is detected by both touch and pressure that produces a degree of displacement, which can avoid accidental operation and give full play to the advantages of the capacitive touch panel.

[0096] Based on the above solution, in the vehicle display screen with integrated physical switch of this utility model, the physical switch further includes: a light-emitting part, which is electrically connected to the control circuit board and can provide optical feedback to the user of the physical switch by changing the light-emitting state; and / or a speaker, which is electrically connected to and communicates with the control circuit board and can provide acoustic feedback to the user of the physical switch by emitting sound.

[0097] According to the above scheme, operation feedback can be provided to users in multiple ways, and users can also confirm the status of the corresponding function by visually inspecting the physical switch.

[0098] Based on the above solution, in the vehicle display screen with integrated physical switch of this utility model, the physical switch is installed on the housing of the vehicle screen and becomes an integral part of the vehicle screen.

[0099] The above solution can reduce the number of parts and lower the management costs for OEMs.

[0100] Based on the above solution, in the vehicle display screen with integrated physical switch of this utility model, the control circuit board of the physical switch communicates with the microcontroller of the vehicle screen.

[0101] According to the above scheme, the corresponding UI will be displayed on the vehicle screen in sync with the operation of the physical switch 120.

[0102] Another aspect of this invention is a motor vehicle equipped with an in-vehicle display screen featuring the aforementioned integrated physical switch.

[0103] The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above description and various modifications can be implemented.

[0104] In the above explanation, with Figures 4 to 8 The physical switch 120 is illustrated using a capacitive push-to-vibrate switch as an example, but it can be replaced with other physical switches 120 known in the art.

[0105] In the above description, the vehicle display screen 100 is preferably a vehicle center console screen, but it can be used for displays installed in other parts of a motor vehicle.

[0106] In the above description, the case in which the pressure is detected by contact between the support column 1222 of the bracket 122 and the pressure-sensitive part 1242 is used as an example, but other solutions can be adopted in which the movable part contacts the pressure-sensitive part 1242 without setting the support column 1222.

[0107] In the above description, the case in which the physical switch 120 has a middle shell 123 and a rear shell 125 is used as an example. However, the physical switch 120 may not have a middle shell 123, or the physical switch 120 may not have a middle shell 123 and a rear shell 125 and the control circuit board 124 may be directly integrated into the back shell of the vehicle screen or other components.

[0108] In the above description, the number of elastic components 1233, pressure-sensitive parts 1242, light-emitting parts 1241, and vibration motors 126 used in the physical switch 120 is not limited to the scheme shown in the figure, and can be increased or decreased according to actual needs.

[0109] In the above description, an example of the light-emitting part 1241, pressure-sensitive part 1242, display part 1243, and speaker being directly disposed on the control circuit board 124 was illustrated. However, the present invention is not limited thereto. The light-emitting part 1241, pressure-sensitive part 1242, display part 1243, and speaker can be electrically connected to the control circuit board 124 as long as they can be connected.

[0110] In the above embodiment, the vibration motor 126, the light-emitting part 1241, the pressure-sensitive part 1242, the display part 1243, and the speaker are not essential components of the physical switch 120 and can be provided according to actual needs.
