Description

Technical Field

[0001] This article relates to a vehicle-mounted display device, a vehicle, and a control method. Background Art

[0002] In existing passenger cars, the size of the central control screen is getting larger and larger. If the overly large central control screen is fixed in an upper position, it can improve the viewing experience after the seats are folded down, but it will block the driver's field of view, which is not conducive to driving safety; if the central control screen is fixed in a lower position, although it can avoid blocking the driver's field of view, it will reduce the viewing experience after the seats are folded down.

[0003] To meet these diverse usage scenarios, some cars have screens installed in both the driver's seat and the passenger seat, or even multiple screens working together. However, using multiple screens is costly and imposes significant constraints on the dashboard's design. Summary of the Invention

[0004] The present application provides a vehicle-mounted display device, comprising:

[0005] base;

[0006] A mounting bracket, slidably connected to the base;

[0007] a screen connected to the mounting bracket;

[0008] A driving mechanism, configured to drive the mounting bracket to slide relative to the base;

[0009] Wherein, the sliding track of the mounting bracket relative to the base is arc-shaped.

[0010] In an exemplary embodiment, the mounting bracket is provided with a slide groove extending along an arc, and the base is provided with an arc-shaped slide rail;

[0011] The slide rail extends into the slide groove, and the slide groove extends along the slide rail.

[0012] In an exemplary embodiment, the slide rail includes a first limiting portion and a connecting portion located in the slide groove;

[0013] The opening of the slide groove is a constricted opening, the width of the first limiting portion is greater than the width of the opening, the connecting portion is passed through the opening, and one end is connected to the first limiting portion and the other end is connected to the mounting bracket.

[0014] In an exemplary embodiment, the first limiting portion is configured as an arc-shaped structure.

[0015] In an exemplary embodiment, two slide grooves and two slide rails are provided, and the two slide rails are aligned with each other;

[0016] The two slide rails extend into the two slide grooves respectively.

[0017] In an exemplary embodiment, the driving mechanism includes:

[0018] A connecting rod, one end of which is provided with a strip-shaped hole;

[0019] A sliding shaft connected to the mounting bracket, passing through the strip hole and capable of sliding along the strip hole;

[0020] a driving shaft, fixedly connected to one end of the connecting rod away from the strip-shaped hole and rotatably connected to the base; and

[0021] a motor assembly, configured to drive the drive shaft to rotate;

[0022] The sliding axis and the driving axis are parallel to each other, and the extending direction of the cross section of the strip-shaped hole is perpendicular to the sliding axis.

[0023] In an exemplary embodiment, the drive shaft is spline-connected to the connecting rod.

[0024] In an illustrative embodiment, the driving mechanism further includes a motor bracket;

[0025] The motor bracket is connected to the base, the housing of the motor assembly is connected to the motor bracket, and the output shaft of the motor assembly is spline-connected to the drive shaft.

[0026] In an exemplary embodiment, the motor assembly includes a motor and a reducer;

[0027] The reducer is transmission-connected to the motor and the drive shaft.

[0028] The present application also proposes a car, comprising the vehicle-mounted display device as described above.

[0029] This application also proposes a control method, which includes:

[0030] When the vehicle door is opened, the driving mechanism drives the mounting bracket to rise to the highest position, and then drives the mounting bracket to descend to the preset position; when the vehicle door is locked, the driving mechanism drives the mounting bracket to descend to the lowest position; and / or

[0031] When the car is in a stopped state and receives a movie viewing instruction, the driving mechanism drives the mounting bracket to rise to the highest position and simultaneously folds down the seat back;

[0032] After receiving the track command, the driving mechanism drives the mounting bracket to descend to the lowest position.

[0033] Before the car starts moving, the drive mechanism drives the mounting bracket to slide downward relative to the base, causing the height of the mounting bracket and the screen to drop simultaneously. This prevents the screen from obstructing the driver's field of view and improves driving safety. After the car stops and the seats are folded down, the drive mechanism drives the mounting bracket to slide upward relative to the base, causing the height of the mounting bracket and the screen to rise simultaneously. Furthermore, due to the arc-shaped sliding path of the mounting bracket, when the mounting bracket and the screen reach their highest position, the screen can be tilted downward, making it perpendicular to the line of sight of the occupant in the car seat, thereby improving the occupant's viewing experience.

[0034] Therefore, the vehicle-mounted display device in this application can meet the needs of different usage scenarios, reduces costs compared to the design of multiple screens in the prior art, and can also increase the technological sense of the entire vehicle.

[0035] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present application. Other advantages of the present application can be realized and obtained by the solutions described in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] like Figures 1 to 3 As shown, Figures 1 to 3The structure of an in-vehicle display device 100 according to this embodiment is shown. The in-vehicle display device 100 includes a base 2, a mounting bracket 3, a screen 1, and a drive mechanism 4. The base 2 is fixedly connected to the vehicle body. The mounting bracket 3 is slidably connected to the base 2 and can slide upward and downward. The screen 1 is fixed to the side of the mounting bracket 3 facing away from the base 2 and can move upward and downward driven by the mounting bracket 3. The drive mechanism 4 is used to drive the mounting bracket 3 to slide.

[0043] A slide rail 21 is provided on the base 2. It is located on one side of the base 2 and protrudes from the base 2. The slide rail 21 is constructed as a strip and is arc-shaped. It arches toward the side of the base 2. The slide rail 21 extends from the top to the bottom of the base 2, with one end of the slide rail 21 facing upward and the other facing downward.

[0044] The screen 1 may be an LED display screen. The screen 1 includes a front side and a back side opposite to the front side. The front side of the screen 1 is provided with a display area, which can display images.

[0045] The mounting bracket 3 comprises a bracket body 31, a connecting protrusion 32, and two connecting seats 33. The bracket body 31 is constructed in a roughly plate-like structure. It covers the back of the screen 1. The bracket body 31 and the screen 1 can be connected by screws or snaps. The bracket body 31 can be embedded in the back of the screen 1. The connecting protrusion 32 is connected to the mounting bracket 3. The connecting protrusion 32 is located on the side of the bracket body 31 facing away from the screen 1 and protrudes from the bracket body 31. The connecting protrusion 32 is strip-shaped, with one end facing upward and the other facing downward. A sliding groove 321 is provided on the connecting protrusion 32. The sliding groove 321 extends along the connecting protrusion 32, with its two ends extending to opposite ends of the connecting protrusion 32. The opening of the sliding groove 321 faces the side facing away from the bracket body 31. The sliding groove 321 is constructed as an arc-shaped strip groove, arching toward the side facing away from the screen 1. One end of the slide groove 321 faces upward, and the other end faces downward. Two connecting seats 33 are arranged on the side of the bracket body 31 facing away from the screen 1. The two connecting seats 33 are spaced apart.

[0046] like Figure 4 As shown, the slide rail 21 on the base 2 extends into the slide groove 321 of the mounting bracket 3, and the extension direction of the slide rail 21 is the same as the extension direction of the slide groove 321. Thus, the mounting bracket 3 can only slide along the slide rail 21 of the base 2, and the sliding path of the mounting bracket 3 along the slide rail 21 is a circular trajectory. The base 2 is also provided with a mounting groove 22. First axial holes 23 are provided on opposite side walls of the mounting groove 22. The first axial holes 23 are circular through holes. The two first axial holes 23 are coaxially arranged. The axes of the two first axial holes 23 are both perpendicular to the extension direction of the slide rail 21.

[0047] like Figure 1 、 5 As shown, the driving mechanism 4 is provided on the base 2, and is used to drive the mounting bracket 3 to slide along the slide rail 21. The driving mechanism 4 includes a connecting rod 44, a sliding shaft 45, a driving shaft 43, a motor bracket 42 and a motor assembly 41.

[0048] The connecting rod 44 can be configured as a straight bar. A strip-shaped hole 442 is provided at one end of the connecting rod 44, and a second axial hole 441 is provided at the other end. Both the strip-shaped hole 442 and the second axial hole 441 extend through the connecting rod 44. The depths of the strip-shaped hole 442 and the second axial hole 441 are the same and perpendicular to the extension direction of the connecting rod 44. The cross-section of the strip-shaped hole 442 is configured as a straight bar, and the extension direction of the cross-section of the strip-shaped hole 442 is the same as the extension direction of the connecting rod 44. The connecting rod 44 is disposed within the mounting slot 22 of the base 2, and the second axial hole 441 of the connecting rod 44 is coaxially disposed with the first axial hole 23 of the base 2.

[0049] The drive shaft 43 is constructed in a straight bar shape. The drive shaft 43 is inserted into the second shaft hole 441 of the connecting rod 44. The drive shaft 43 is key-connected to the connecting rod 44, and the drive shaft 43 and the connecting rod 44 can be spline-connected. The drive shaft 43 cannot rotate in the second shaft hole 441 of the connecting rod 44. The opposite ends of the drive shaft 43 extend out of the second shaft hole 441, and the two ends of the drive shaft 43 are also inserted into the two first shaft holes 23 of the base 2 respectively. There is a clearance fit between the drive shaft 43 and the first shaft hole 23, and the drive shaft 43 can rotate in the first shaft hole 23. The drive shaft 43 is fixedly connected to the connecting rod 44 and is rotatably connected to the base 2. The connecting rod 44 can swing relative to the base 2 around the axis of the drive shaft 43.

[0050] The motor bracket 42 is fixed to the side of the base 2 facing away from the mounting bracket 3. The motor bracket 42 and the base 2 can be connected by snap-fit ​​connection, welding, screw connection or bonding. The motor bracket 42 can be constructed as a roughly plate-like structure. The motor bracket 42 extends from the side of the base 2 facing away from the mounting bracket 3 to the side facing away from the mounting bracket 3. The motor bracket 42 is located on one side of the drive shaft 43, and the plate surface of the motor bracket 42 is perpendicular to the drive shaft 43. A through hole 421 is provided on the motor bracket 42, and the through hole 421 vertically passes through the motor bracket 42, and the through hole 421 is aligned with the drive shaft 43.

[0051] The housing of the motor assembly 41 is fixed to the motor bracket 42. The housing of the motor assembly 41 and the motor bracket 42 can be screwed. The motor assembly 41 is located on the side of the motor bracket 42 facing away from the drive shaft 43. The output shaft 411 of the motor assembly 41 is coaxially arranged with the sliding shaft 45. The output shaft 411 of the motor assembly 41 passes through a through hole in the motor bracket 42 and is fixedly connected to the sliding shaft 45. The output shaft 411 of the motor assembly 41 and the sliding shaft 45 can be connected by a coupling, or the output shaft 411 of the motor assembly 41 and the sliding shaft 45 can be splined.

[0052] The sliding shaft 45 is configured as a straight bar. It passes through the bar-shaped hole 442 and can slide along it. The direction in which the sliding shaft 45 extends is perpendicular to the direction in which the cross section of the bar-shaped hole 442 extends. There is a clearance fit between the sliding shaft 45 and the bar-shaped hole 442, allowing the sliding shaft 45 to slide along the direction in which the cross section of the bar-shaped hole 442 extends. The end of the connecting rod 44 in which the bar-shaped hole 442 is located is positioned between the two connecting seats 33 of the mounting bracket 3. The ends of the sliding shaft 45 are connected to the two connecting seats 33 of the mounting bracket 3, respectively.

[0053] The base 2 of the vehicle-mounted display device 100 can be fixed to the dashboard of a car, with the front of the screen 1 facing the rear of the car. Before the car is driven, the output shaft 411 of the motor assembly 41 can be used to drive the drive shaft 43 to rotate, causing the connecting rod 44 to swing downward. As the connecting rod 44 swings downward, the connecting rod 44 presses the sliding shaft 45 downward, and the sliding shaft 45 moves downward along the connecting rod 44. During this downward movement, the sliding shaft 45 also slides along the strip hole 442 toward the drive shaft 43. During this downward movement, the sliding shaft 45 also drives the mounting bracket 3 downward. At this time, the driving mechanism 4 drives the mounting bracket 3 to slide downward relative to the base 2, causing the height of the mounting bracket 3 and the screen 1 to drop synchronously, thereby preventing the screen 1 from blocking the driver's field of view and improving driving safety. After the car stops and the seat is folded down, the output shaft 411 of the motor assembly 41 can be used to drive the drive shaft 43 to rotate, so that the connecting rod 44 swings upward. When the connecting rod 44 swings upward, the connecting rod 44 lifts the sliding shaft 45 upward, and the sliding shaft 45 moves upward with the connecting rod 44. During the upward movement, the sliding shaft 45 also slides along the bar hole 442 in the direction away from the drive shaft 43. During the upward movement, the sliding shaft 45 also drives the mounting bracket 3 to move upward. At this time, the driving mechanism 4 drives the mounting bracket 3 to slide upward relative to the base 2, so that the height of the mounting bracket 3 and the screen 1 rises synchronously. At the same time, since the sliding trajectory of the mounting bracket 3 is arc-shaped, when the mounting bracket 3 and the screen 1 rise to the highest position, the screen 1 can face diagonally downward, so that the screen 1 is perpendicular to the line of sight of the occupant on the car seat, thereby improving the viewing experience of the occupant.

[0054] In an illustrative embodiment, Figure 4 As shown, the slide rail 21 includes a first limiting portion 211 and a connecting portion 212. The first limiting portion 211 is configured as an arc-shaped plate-like structure. The first limiting portion 211 is disposed within the slide groove 321, with one plate surface of the first limiting portion 211 facing the bottom of the slide groove 321. The slide groove 321 can only slide along the first limiting portion 211.

[0055] The connecting portion 212 is disposed on the surface of the first limiting portion 211 facing away from the chute 321. One side of the connecting portion 212 is connected to the first limiting portion 211, and the other side of the connecting portion 212 is connected to the base 2. The connecting portion 212 can be configured as a strip structure, and the extending direction of the connecting portion 212 is the same as the extending direction of the first limiting portion 211.

[0056] The width of the opening of the sliding groove 321 is smaller than the width of the first limiting portion 211 , the width of the connecting portion 212 is smaller than the width of the opening of the sliding groove 321 , and the connecting portion 212 extends out of the sliding groove 321 from the opening of the sliding groove 321 .

[0057] Since the opening width of the slide groove 321 is smaller than the width of the first limiting portion 211 , the first limiting portion 211 is difficult to escape from the slide groove 321 , making it difficult to separate the mounting bracket 3 from the base 2 .

[0058] In an illustrative embodiment, Figure 2 As shown, the mounting bracket 3 has two connecting protrusions 32, both located on the surface of the bracket body 31 facing away from the screen 1. The two connecting protrusions 32 are separated and located on opposite sides of the bracket body 31. Both connecting protrusions 32 are provided with a slide groove 321, extending in the same direction.

[0059] Two slide rails 21 are provided on the base 2. Both slide rails 21 are located on one side of the base 2 close to the mounting bracket 3. The two slide rails 21 extend in the same direction. The distance between the two slide rails 21 is equal to the distance between the two slide slots 321.

[0060] The two slide rails 21 on the base 2 extend into the two slide grooves 321 on the mounting bracket 3 respectively, and the first limiting portion 211 of each slide rail 21 is difficult to disengage from the two slide grooves 321 .

[0061] In this way, the two slide grooves 321 of the mounting bracket 3 cooperate with the two slide rails 21 of the base 2 to make the sliding connection between the mounting bracket 3 and the base 2 more stable, and the mounting bracket 3 is also more stable when sliding.

[0062] In one exemplary embodiment, the motor assembly 41 includes a motor and a reducer. The motor and reducer may be integrally formed. The motor may be a Hall effect motor. The reducer's input shaft is connected to the motor's main shaft, and the reducer's output shaft 411 is connected to the drive shaft 43.

[0063] In this way, the reducer is transmission-connected to the motor and the drive shaft 43 , and the reducer can reduce the speed and increase the torque input by the motor and then input it to the drive shaft 43 .

[0064] This embodiment also provides a car, which includes the vehicle-mounted display device 100 as described above.

[0065] This embodiment also provides a method for controlling a vehicle. The method is implemented based on the above-mentioned vehicle and includes the following steps:

[0066] When the door is opened, the driving mechanism 4 drives the mounting bracket 3 to rise to the highest position, and then drives the mounting bracket 3 to descend to the preset position. When the door is locked, the driving mechanism 4 drives the mounting bracket 3 to descend to the lowest position.

[0067] The in-vehicle display device 100 also includes a controller 5. The controller 5 is electrically connected to the motor of the in-vehicle display device 100. When the vehicle door is opened, the controller 5 receives a door-opening signal. Upon receiving the door-opening signal, the controller 5 drives the motor of the drive mechanism 4 to rotate, causing the mounting bracket 3 to slide upward to its highest position. After the mounting bracket 3 reaches its highest position, the motor is then driven to rotate in the opposite direction, causing the mounting bracket 3 to slide to a preset position, which may be the position previously set by the user.

[0068] In this way, when a passenger gets on or opens the door, the vehicle enters the welcoming / farewell mode, first raising the screen 1 to the highest position and then lowering it to the preset position to express welcome or farewell. When the passenger gets off and locks the door, the controller 5 can receive a vehicle lock signal, and upon receiving the vehicle lock signal, the controller 5 drives the mounting bracket 3 to descend to the lowest position, thereby retracting the screen 1.

[0069] In an exemplary embodiment, the control method further includes the following steps:

[0070] When the car is in a stopped state, upon receiving a movie viewing instruction, the driving mechanism 4 drives the mounting bracket 3 to rise to the highest position and simultaneously folds down the seat back.

[0071] The viewing instruction can be sent by the passenger by sending a voice command, a gesture command, or triggering a button. After receiving the viewing instruction, the controller 5 enters the viewing mode. The controller 5 drives the motor to raise the mounting bracket 3 from its current position to the highest position and recline the backrest of the car seat, so that the passenger can lie in the seat and watch the content displayed on the screen 1, providing a better viewing experience.

[0072] In the movie viewing mode, the passenger can also adjust the height of the mounting bracket 3 by sending voice commands, gesture commands or triggering buttons.

[0073] In an exemplary embodiment, the control method further includes the following steps:

[0074] After receiving the track instruction, the driving mechanism 4 drives the mounting bracket 3 to descend to the lowest position.

[0075] The track command can be sent by the passenger in the form of a voice command, a gesture command, or a button trigger. After receiving the track command, the controller 5 enters the track mode and drives the motor to lower the mounting bracket 3 from the current position to the lowest position.

[0076] In this way, the driver's sight will not be blocked when the vehicle is driving.

[0077] In an exemplary embodiment, the control method further includes the following steps:

[0078] The driving mechanism 4 drives the mounting bracket 3 to rise when receiving an ascending instruction, and drives the mounting bracket 3 to descend when receiving a descending instruction.

[0079] In this way, the height of the screen 1 can be freely adjusted during daily use.
