For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned description of the drawings are intended to cover non-exclusive inclusions.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] At present, cars on the market are equipped with a central control screen for touch display, which has become the mainstream terminal for human-vehicle interaction. Among them, the central control screen, i.e. the on-board screen, can divide the entire touch display interface into function selection area, information display area and vehicle control area during human-vehicle interaction. The driver mainly operates and accesses the vehicle by pressing and sliding the screen with his fingers.

[0040] Existing in-vehicle screens are generally touch screens, which require the driver's vision and touch to complete the human-vehicle interaction operation. That is, due to the large in-vehicle screen, the driver needs to locate the position of the required function button on the screen by vision, and then touch the function button with a finger to trigger it. Among them, the driver needs a certain amount of time to observe the content on the screen, and most of the human-vehicle interaction is carried out while the driver is driving. When the driver's line of sight is shifted to the in-vehicle screen, it will cause a great safety hazard.

[0041] The present application provides a floating button and a vehicle-mounted screen, which are used to reduce the time a driver needs to visually observe screen content during human-vehicle interaction, so that the driver can complete the human-vehicle interaction operation by operating the floating button, thereby reducing safety hazards during driving.

[0042] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of a vehicle-mounted screen provided in an embodiment of the present application is as follows: wherein the vehicle-mounted screen 100 includes a touch display screen 110 and a floating button 120 .

[0043] In an embodiment of the present application, the touch display screen 100 is connected to the center console of the car through a rotary motor and a rotary motor bracket in sequence, that is, the rotary motor bracket is fixed to the center console of the car, the rotary motor is arranged on the rotary motor bracket, and the rotating shaft of the rotary motor is connected to the back plate of the touch display screen 100. By controlling the rotary motor to rotate, the touch display screen 100 can be controlled to display in landscape and portrait modes.

[0044] The floating button 120 can be connected to the rotating motor bracket to be suspended beside one side of the touch display screen 100, for example, it can be suspended beside the lower side of the touch display screen 100, or suspended beside the left side of the touch display screen 100, etc., which is not limited here.

[0045] In some embodiments, when the touch screen 100 rotates to switch between the horizontal and vertical modes, the floating button 120 can be fixed in position. For example, in the horizontal mode of the touch screen 100, the floating button 120 is next to the current lower side of the touch screen 100. After the touch screen 100 switches to the vertical mode, the floating button 120 is still next to the current lower side of the touch screen 100. Since the position of the floating button 120 is fixed and unchanged, the driver can form an operation memory after long-term use, which is conducive to the driver to operate the floating button 120 through the operation memory without visual observation during driving, thereby further reducing the risk of human-vehicle interaction during driving.

[0046] Please refer to Figure 2 , Figure 2The structure diagram of a floating button provided by an embodiment of the present application is shown in FIG.

[0047] In an embodiment of the present application, the adapter plate is used to electrically connect the controller and power supply of the vehicle-mounted screen through a signal line. The fixing seat 210 is provided with a receiving space, and the adapter plate is arranged in the receiving space. The fixing seat 210 is used to connect the rotating motor bracket of the vehicle-mounted screen. The button bracket 220 is arranged on the fixing seat 210. The button module 230 is arranged on the bracket and suspended beside one side of the vehicle-mounted screen. The button module 230 includes a plurality of buttons 231 arranged along the extension direction of the side, and the button 231 is electrically connected to the adapter plate. The button 231 is used to transmit the corresponding button data to the controller through the adapter plate when triggered.

[0048] The adapter board can receive the control signal transmitted by the controller of the vehicle-mounted screen and forward the control signal to the key module 230. At the same time, the adapter board also receives the key data of the key module 230 and transmits the key data to the controller of the vehicle-mounted screen so that the controller executes the corresponding control instructions according to the key data. In addition, the adapter board is connected to the power supply of the vehicle-mounted screen, receives the power supply voltage provided by the power supply, converts the power supply voltage into the power supply voltage required by the key module 230, and transmits the power supply voltage to the key module 230 to drive the key module 230.

[0049] In the embodiment of the present application, a receiving space is provided in the fixing seat 210 to receive the adapter plate, and the receiving space of the fixing seat 210 is provided with a through hole so that the adapter plate provided in the fixing seat 210 can be electrically connected to the vehicle-mounted screen through a signal line. In addition, the fixing seat 210 is connected to the rotating motor bracket through a connector to be fixed on the rotating motor bracket. For example, screw holes are provided at corresponding positions of the fixing seat 210 and the rotating motor bracket, and screws are used as connectors to match the screw holes to connect the fixing seat 210 to the rotating motor bracket.

[0050] It can be understood that in the embodiment of the present application, a fixed base 210 is provided to be connected to a rotating motor bracket of the vehicle-mounted screen, a button bracket 220 is provided to be connected to the fixed base 210, and a button module 230 is provided to be connected to the button bracket 220, so that the button module 230 is suspended beside one of the side edges of the vehicle-mounted screen, and an adapter plate is provided in the receiving space of the fixed base 210, and the button data is transmitted to the controller of the vehicle-mounted screen by using the adapter plate, so that when the driver needs to interact with the vehicle-mounted screen, it can be achieved by operating the button 231 on the button module 230, thereby reducing the time the driver observes the screen content through vision, thereby reducing the safety hazard while driving.

[0051] Please refer to Figure 3 , is a side view of a floating button provided in an embodiment of the present application. The button bracket 220 includes a first support arm 221, a second support arm 222, a third support arm 223 and a fourth support arm 224 connected in sequence. The first support arm 221 is also used to connect to one side of the fixing base 210, and the extension direction of the first support arm 221 is perpendicular to the side of the fixing base 210 to which it is connected. The fourth support arm 224 is also used to connect to the button module 230. There is a first angle A between the first support arm 221 and the second support arm 222, there is a second angle B between the second support arm 222 and the third support arm 223, and there is a third angle C between the third support arm 223 and the fourth support arm 224, wherein the first angle A, the second angle B and the third angle C are all greater than or equal to 90 degrees and less than or equal to 180 degrees, and the lengths of the first support arm 221, the second support arm 222, the third support arm 223 and the fourth support arm 224 decrease successively, so that the key bracket 220 formed by the first support arm 221, the second support arm 222, the third support arm 223 and the fourth support arm 224 is a J-shaped bracket. It can be understood that the button bracket 220 composed of the first support arm 221, the second support arm 222, the third support arm 223 and the fourth support arm 224 can extend from the back of the vehicle screen to the front of one side of the vehicle screen after the fixed base 210 is connected to the rotating motor bracket of the vehicle screen, so that the button module 230 can be suspended next to one side of the vehicle screen.

[0052] In some embodiments, the button bracket 220 can also be a J-shaped bracket with a smooth transition. After the fixing base 210 is connected to the rotating motor bracket of the vehicle screen, the button module 230 can be suspended next to one side of the vehicle screen. No limitation is made here.

[0053] The button bracket 220 may also be provided with a wiring space connected to the receiving space, and a signal line electrically connecting the button 231 and the adapter board may be arranged in the wiring space.

[0054] Please refer to Figure 4 , is a front view of a floating button provided in an embodiment of the present application. The button module 230 includes a row of buttons 231, and the arrangement direction of the multiple buttons 231 is consistent with the extension direction of the side adjacent to the vehicle screen, so that the buttons 231 and the content corresponding to the buttons 231 can be displayed at the corresponding position of the vehicle screen, and the driver can operate the buttons 231 conveniently.

[0055] In some embodiments, the most commonly used function buttons on the vehicle screen can be set as multiple buttons 231 in the button module 230. For example, the multiple buttons 231 in the above figure may include a combination button for adjusting the temperature up and down on the left side of the vehicle, a combination button for adjusting the fan up and down, a Home button (return to the main interface button), a combination button for adjusting the volume up and down, and a combination button for adjusting the temperature up and down on the right side, etc.

[0056] In some embodiments, the adapter board is provided with a preset type of interface. When the adapter board is provided in the receiving space of the fixing seat 210, the preset type of interface is provided outside the fixing seat 210 through the through hole of the fixing seat 210, so that the adapter board can be connected to an external signal line with a corresponding plug through the interface. The vehicle-mounted screen can also be provided with the preset type of interface, so that the adapter board with the preset type of interface can be electrically connected to the vehicle-mounted screen through a signal line with a corresponding plug.

[0057] In the embodiment of the present application, the button module 230 further includes a liquid crystal display screen 232, which is arranged on one side of the plurality of buttons 231. The liquid crystal display screen 232 is electrically connected to the adapter board, and the liquid crystal display screen 232 is used to display the function pattern of the button 231 at the position corresponding to the button 231. As shown in the figure, the liquid crystal display screen 232 can be arranged above the plurality of buttons 231, and is electrically connected to the adapter board to receive the power supply voltage for display work, and also receives the function pattern of the button 231 forwarded by the adapter board to the controller, so as to display it at the position corresponding to the button 231, so as to indicate the function of each button 231 to the driver.

[0058] In some embodiments, the LCD screen 232 is oriented in the same direction as the vehicle-mounted screen. Alternatively, the LCD screen 232 has an angle D relative to the vertical line of the space, and the angle D is an acute angle, which makes the LCD screen 232 oriented obliquely upward, so that the driver can more easily observe the content displayed on the LCD screen 232, thereby reducing the driver's observation time and further reducing safety hazards during driving.

[0059] The LCD screen 232 is also used to receive and display the trigger information of the button 231 sent back by the controller. For example, after the driver increases the air volume through the fan increase button 231, the controller can send an adjustment success message to the LCD screen 232, and the LCD screen 232 can display the corresponding pre-stored text prompt, or graphic prompt, etc. after receiving the adjustment success message.

[0060] In the present application embodiment, Figure 3 As shown, there is an angle E between the liquid crystal display screen 232 and the plane of the plurality of buttons 231, and the angle E is greater than 90 degrees and less than 180 degrees. Figure 3It can be understood that when the orientation of the LCD display 232 is consistent with the vehicle-mounted screen, the planes of the multiple buttons 231 are oriented obliquely upward, which makes it easier for the driver to observe the positions of the multiple buttons 231 and to press and trigger the button 231, thereby reducing the overall time the driver spends operating the button module 230 and further reducing safety hazards during driving.

[0061] In the embodiment of the present application, the adapter board disposed inside the receiving space of the fixing seat 210 includes a CAN Bus interface 241 (CANBus, Controller Area Network Bus, Controller Area Network Bus) and a data conversion unit, such as Figure 3 As shown, a through hole penetrating the receiving space is disposed on one side of the fixing seat 210 , and the profile of the through hole is consistent with the profile of the CAN Bus interface 241 , so that the CAN Bus interface 241 can pass through the through hole from the receiving space.

[0062] The data conversion unit is connected to the button 231, and is used to receive the analog signal generated by the button 231 when it is triggered, and convert the analog signal into button data of the CAN bus data type. The CAN Bus interface 241 is electrically connected to the controller and the power supply through the CAN bus, and is used to transmit the button data to the controller.

[0063] In the scenario where the key module 230 also includes a liquid crystal display 232, the adapter board disposed inside the receiving space of the fixing base 210 also includes an LVDS interface 242 (LVDS, Low-Voltage Differential Signaling) and a de-sequencing unit. Similarly, another through hole penetrating the receiving space is also disposed on one side of the fixing base 210, and the contour of the other through hole is also consistent with the contour of the LVDS interface 242, so that the LVDS interface 242 can pass through the other through hole from the receiving space.

[0064] The LVDS interface 242 is electrically connected to the controller via a twisted pair cable, and the LVDS interface 242 is used to receive the image signal transmitted by the controller. The deserialization unit is electrically connected to the liquid crystal display 232, and the deserialization unit is used to deserialize the image signal and transmit the processed image signal to the liquid crystal display 232, so that the liquid crystal display 232 displays the function pattern of the key 231 at the position corresponding to the key 231.

[0065] In some embodiments, the CAN Bus interface 241 and the data conversion unit may constitute a first adapter board, the LVDS interface 242 and the deserialization unit may constitute a second adapter board, and the first adapter board and the second adapter board may be accommodated in the receiving space of the fixing base 210 at the same time.

[0066] The embodiment of the present application provides a vehicle-mounted screen, including any floating button in the above embodiment. It can be understood that the beneficial effects that can be achieved by the vehicle-mounted screen provided by the embodiment of the present application can refer to the beneficial effects of the corresponding floating button provided above, and will not be repeated here.

[0067] The embodiments described above are merely preferred embodiments of the present application and are not intended to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary technicians in this field should fall within the protection scope determined by the claims of the present application.
