Description

Technical Field

[0001] This invention relates to the field of intelligent driving equipment technology for vehicles, specifically to a flip-up mobile display structure for autonomous driving. Background Technology

[0002] With technological advancements, automobiles are becoming increasingly intelligent, and autonomous driving functions are nearing commercialization, greatly increasing the feasibility of widespread adoption. However, people will not relinquish the enjoyment of driving themselves. Therefore, in the era of autonomous driving, cars should possess two driving modes: autonomous driving and driver-driven operation for a more immersive driving experience. When the driver is driving, the display screen in front of them needs to consider the driver's field of vision and steering wheel placement; the screen should be relatively small to avoid obstructing the driver's view. When in autonomous driving mode, the steering wheel retracts, requiring a larger screen to provide the driver with a richer entertainment experience. Existing vehicle displays only offer rotation or vertical movement, failing to meet the varying comfort and adjustment requirements of different drivers in different driving modes. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide a flip-up mobile display screen structure with rotation, up-down movement and forward-backward movement functions, which can meet the visual comfort requirements of different drivers and the functional requirements of different driving modes.

[0004] To achieve this objective, the present invention provides a rotatable mobile display structure for autonomous driving, comprising a cuboid display screen, wherein the upper surface and front surface of the display screen are respectively provided with display surfaces of different sizes. The display screen is rotatably connected to a display screen bracket about a horizontal axis; the display screen bracket is mounted on a guide rail base, the guide rail base is provided with a front-to-back moving guide rail, a front-to-back moving slider cooperating with the front-to-back moving guide rail is fixed on the display screen bracket, and a front-to-back driving mechanism for driving the front-to-back moving slider to move along the front-to-back moving guide rail is fixed on the guide rail base; a lifting driving mechanism is provided below the guide rail base, and the guide rail base is fixed to the power output end of the lifting driving mechanism.

[0008] Furthermore, the front and rear drive mechanism includes a sliding motor fixed on the guide rail seat and located behind the display screen bracket, and a sliding drive wheel coaxially fixed on the motor shaft of the sliding motor. The sliding drive wheel drives the first front and rear moving slider and the second front and rear moving slider to move forward or backward simultaneously along the first front and rear moving guide rail and the second front and rear moving guide rail, respectively, through sliding wire drawing.

[0009] Furthermore, a set of pulleys is fixed on the left and right sides of the guide rail base, namely the first pulley set and the second pulley set. One end of the sliding wire drawing is fixed to the sliding drive wheel, and the other end passes around the first pulley set and the second pulley set and is fixed to the sliding drive wheel. The first forward and backward moving slider is fixed on the sliding wire drawing section that passes around the first pulley set, and the second forward and backward moving slider is fixed on the sliding wire drawing section that passes around the second pulley set.

[0010] Furthermore, the first pulley group includes a first pulley with its axis arranged vertically, a second pulley located in front of the first pulley and with its axis arranged horizontally, a third pulley located below the second pulley and with its axis arranged horizontally, a fourth pulley located behind the third pulley and with its axis arranged horizontally, and a fifth pulley located above the third pulley, with its axis arranged horizontally and perpendicular to the axis of the fourth pulley; the sliding wire sequentially passes around the first pulley, the second pulley, the third pulley, the fourth pulley, and the fifth pulley.

[0011] Furthermore, the second pulley group includes a sixth pulley with its axis arranged horizontally, a seventh pulley located below the sixth pulley with its axis arranged horizontally and perpendicular to the sixth pulley, an eighth pulley located in front of the seventh pulley with its axis arranged parallel to the axis of the seventh pulley, a ninth pulley located above the eighth pulley with its axis arranged parallel to the eighth pulley, and a tenth pulley located behind the ninth pulley with its axis arranged vertically; the sliding wire sequentially passes around the sixth pulley, the seventh pulley, the eighth pulley, the ninth pulley, and the tenth pulley.

[0012] Furthermore, the lifting drive mechanism includes a hydraulic cylinder and a hydraulic column coaxially connected inside the hydraulic cylinder and driven by the hydraulic cylinder. The top end of the hydraulic column is vertically fixed to the bottom surface of the guide rail seat, and the hydraulic cylinder is connected to a hydraulic pump for supplying oil to it.

[0013] Furthermore, the display screen is located inside the dashboard, and the top and front surfaces of the dashboard have flip grooves for the display screen to flip. A roller blind for sealing the flip grooves on the top surface of the dashboard and a roller blind drive mechanism for driving the roller blind to unfold are fixed inside the dashboard. The rear of the roller blind is fixed to a roller blind shaft, which is rotatably disposed within the roller blind housing. The roller blind housing is fixed inside the dashboard, and a return spring connects the roller blind shaft and the roller blind. The roller blind drive mechanism includes a roller blind drawing motor, and an extension drawing wire is fixed to the power output end of the roller blind drawing motor. The extension drawing wire is fixedly connected to the front of the roller blind.

[0014] The beneficial effects of this invention are as follows: During manual driving, the small screen of the display is positioned in the traditional human-machine interface of a car, ensuring that the driver's forward view is not obstructed. During autonomous driving, the screen is replaced with a large screen, and its position (front / back, up / down) can be adjusted according to the driver's height and preferences, ensuring a comfortable viewing experience. When switching between the large and small screens, the automatic roller blind structure prevents any recesses between the display and the rear area of ​​the dashboard, resulting in a more aesthetically pleasing dashboard appearance.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 —2 shows a flip-up mobile display structure for autonomous driving, including, as shown in Figure 2. Figure 10 — Figure 11The rectangular display screen 1 shown has display surfaces of different sizes on its top and front surfaces. The display screen 1 is connected to the display screen bracket 2 and can be rotated around a horizontal axis. Figure 3 As shown in Figure 4, a display screen shaft 38 is vertically fixed to the left and right surfaces of the display screen 1, respectively. The display screen shaft 38 on one side of the display screen 1 is hinged to the display screen bracket 2. A rotary driven gear 39 is coaxially fixed to the display screen shaft 38 on the other side of the display screen 1. A rotary drive motor 8 is fixed on the display screen bracket 2 to drive the display screen shaft 38 on the other side of the display screen 1 to rotate around its axis. A rotary drive gear 9 that meshes with the rotary driven gear 39 is coaxially fixed to the motor shaft of the rotary drive motor 8.

[0029] The display screen bracket 2 is mounted on the guide rail base 3, which is provided with a front-to-back moving guide rail. A front-to-back moving slider that cooperates with the front-to-back moving guide rail is fixed to the display screen bracket 2. A front-to-back driving mechanism for driving the front-to-back moving slider to move along the front-to-back moving guide rail is fixed to the guide rail base 3. Figure 3 , Figure 5 As shown, a front-to-back moving guide rail is fixed on each of the left and right sides of the guide rail base 3, namely the first front-to-back moving guide rail 4 and the second front-to-back moving guide rail 6. A front-to-back moving slider is fixed on each of the left and right sides of the display screen bracket 2, namely the first front-to-back moving slider 5 set on the first front-to-back moving guide rail 4 and the second front-to-back moving slider 7 set on the second front-to-back moving guide rail 6. Both the first front-to-back moving slider 5 and the second front-to-back moving slider 7 are connected to the front-to-back driving mechanism. The front-to-back driving mechanism includes a sliding motor 10 fixed on the guide rail base 3 and located behind the display screen bracket 2, and a sliding drive wheel 11 coaxially fixed on the motor shaft of the sliding motor 10. The sliding drive wheel 11 drives the first front-to-back moving slider 5 and the second front-to-back moving slider 7 to move forward or backward simultaneously along the first front-to-back moving guide rail 4 and the second front-to-back moving guide rail 6 through the sliding wire 12. A set of pulleys is fixed on the left and right sides of the guide rail base 3, namely the first pulley group and the second pulley group. One end of the sliding wire drawing 12 is fixed to the sliding drive wheel 11, and the other end passes around the first pulley group and the second pulley group and is fixed to the sliding drive wheel 11. The first forward and backward moving slider 5 is fixed on the sliding wire drawing section that passes around the first pulley group, and the second forward and backward moving slider 7 is fixed on the sliding wire drawing section that passes around the second pulley group.

[0030] like Figure 6As shown, the first pulley group includes a first pulley 13 with its axis arranged vertically, a second pulley 14 located in front of the first pulley 13 with its axis arranged horizontally, a third pulley 15 located below the second pulley 14 with its axis arranged horizontally, a fourth pulley 16 located behind the third pulley 15 with its axis arranged horizontally, and a fifth pulley 17 located above the third pulley 15 with its axis arranged horizontally and perpendicular to the axis of the fourth pulley 16; the sliding wire 12 passes around the first pulley 13, the second pulley 14, the third pulley 15, the fourth pulley 16 and the fifth pulley 17 in sequence.

[0031] like Figure 7 As shown, the second pulley group includes a sixth pulley 18 with its axis arranged horizontally, a seventh pulley 19 located below the sixth pulley 18 with its axis arranged horizontally and perpendicular to the sixth pulley 18, an eighth pulley 20 located in front of the seventh pulley 19 with its axis arranged parallel to the axis of the seventh pulley 19, a ninth pulley 21 located above the eighth pulley 20 with its axis arranged parallel to the eighth pulley 20, and a tenth pulley 22 located behind the ninth pulley 21 with its axis arranged vertically; the sliding wire 12 passes around the sixth pulley 18, the seventh pulley 19, the eighth pulley 20, the ninth pulley 21, and the tenth pulley 22 in sequence.

[0032] like Figure 1 As shown in Figure 2, a lifting drive mechanism is provided below the guide rail seat 3. The guide rail seat 3 is fixed to the power output end of the lifting drive mechanism. The lifting drive mechanism includes a hydraulic cylinder 23 and a hydraulic column 24 coaxially connected inside the hydraulic cylinder 23 and driven by the hydraulic cylinder 23. The top end of the hydraulic column 24 is vertically fixed to the bottom surface of the guide rail seat 3. The hydraulic cylinder 23 is connected to a hydraulic pump 25 for supplying oil to it.

[0033] like Figure 1 —2 and Figure 8 As shown in Figure 9, the display screen 1 is located inside the instrument panel 26. The top and front surfaces of the instrument panel 26 are provided with flip grooves 27 for the display screen 1 to flip. Inside the instrument panel 26, there is a roller blind 28 for sealing the flip grooves 27 on the top surface of the instrument panel 26 and a roller blind drive mechanism for driving the roller blind 28 to unfold. The rear part of the roller blind 28 is fixed to the roller blind shaft 29. The roller blind shaft 29 is rotatably disposed inside the roller blind housing 30. The roller blind housing 30 is fixed inside the instrument panel 26. A return spring is connected between the roller blind shaft 29 and the roller blind 28. The roller blind drive mechanism includes a roller blind pull motor 31. The power output end of the roller blind pull motor 31 is fixed with an extension pull wire 32. The extension pull wire 32 is fixedly connected to the front part of the roller blind 28.

[0034] In this invention, after the driving mode is changed from manual driving mode to automatic driving mode, the driver can switch the small screen 34 to the large screen 33 by operating the screen rotation control button according to their needs. When the rotation button is activated, the roller blind pull motor 31 first receives a signal and drives the roller blind 28 backward to the limit position to leave rotation space. Then, after the screen rotation adjustment is completed for 10 seconds, if there is no other button operation command, the roller blind pull motor 31 drives the roller blind 28 forward to the back of the screen. When the roller blind 28 moves to the area of ​​5mm of the screen shell, the roller blind pull motor 31 receives a signal from the distance sensor at the end of the roller blind 28 and stops driving. The roller blind 28 is fixed at a distance of 5mm from the screen shell (to avoid interference between the roller blind 28 and the screen shell, and at the same time to block the flip groove 27 on the top of the instrument panel 26). When the large screen 33 needs to be adjusted to a suitable position, the roller shutter motor 31 first receives a signal and drives the roller shutter 28 backward to its limit position, leaving room for movement. Then, the sliding motor 10 drives the first forward and backward sliding slider 5 and the second forward and backward sliding slider 7 to move, causing the display screen 1 to move forward and backward. After the screen is adjusted for 10 seconds, if there are no other button operation commands, the roller shutter motor 31 drives the roller shutter 28 forward to the back of the screen. When it moves to the area 5mm from the screen shell, the roller shutter motor 31 receives a signal from the distance sensor at the end of the roller shutter 28 and stops driving. The roller shutter 28 is fixed at a distance of 5mm from the screen shell. When the screen needs to be adjusted to a suitable vertical position via operation, the roller shutter motor 31 first receives a signal and drives the roller shutter 28 backward to its limit position, leaving space for the roller shutter 28 to move vertically. Then, the hydraulic pump 25 injects or extracts oil into the hydraulic cylinder 23, causing the guide rail seat 3 to rise or fall, thereby adjusting the screen position. After the screen is adjusted for 10 seconds, if there are no other button operation commands, the roller shutter motor 31 drives the roller shutter 28 forward to the back of the screen. When it moves to a 5mm area of ​​the screen shell, the roller shutter motor 31 receives a signal from the distance sensor at the end of the roller shutter 28 and stops driving, fixing the roller shutter 28 at a distance of 5mm from the screen shell. After ensuring their own visual comfort and adjusting the screen, the driver can use the large screen 33 to watch movies, play games, and perform other entertainment.

[0035] Switching from autonomous driving mode to manual driving mode: After adjusting the driving mode from autonomous driving mode to manual driving mode, the system automatically detects the screen status. When the screen status is small screen 34 and the position is in the traditional human-machine position (set to HOME position), the system does not operate the screen and locks the screen operation buttons, preventing rotation, vertical movement, and forward / backward movement of the screen; the operation buttons are disabled. When the system automatically detects that the screen status is large screen 33, the roller blind pull motor 31 first receives a signal and drives the roller blind 28 backward to its limit position, leaving room for rotation and movement. Then, it automatically rotates the screen to the small screen state and moves the screen to the HOME position for 10 seconds. After that, the roller blind pull motor 31 drives the roller blind 28 forward to the back of the screen. When it moves to a 5mm area of ​​the screen shell, the roller blind pull motor 31 receives a signal from the distance sensor at the end of the roller blind 28 and stops driving. The roller blind 28 is fixed at a distance of 5mm from the screen shell. Then lock the screen control buttons. During manual driving, the screen cannot be rotated, moved up and down, or moved forward and backward, and the control buttons will be disabled.

[0036] In this invention, during manual driving, the small screen 34 of display screen 1 is positioned in the traditional human-machine interface location of a car, ensuring that the driver's view is not obstructed. During autonomous driving, the screen is replaced with a large screen 33, and its position (front / back, up / down) can be adjusted according to the driver's height and preferences, ensuring a comfortable viewing experience. When switching between the large and small screens, an automatic roller blind structure prevents any recesses between display screen 1 and the rear area of ​​the dashboard 26, resulting in a more aesthetically pleasing dashboard 26.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the structure of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
