Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device and a motor vehicle. Background Technology

[0002] With the development of intelligent connected vehicles, display devices are being used in various applications. When used in motor vehicles, some display screens are fixed in the center of the dashboard, between the driver and passenger seats, and cannot be moved. This prevents the screen from facing the user and makes it impossible to switch between the driver's and passenger's views. Furthermore, in strong sunlight, the screen may reflect light, making it difficult for users to see icons or text, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a display device and a motor vehicle, which offer a good user experience.

[0004] In a first aspect, this application provides a display device, comprising:

[0005] Bracket, including mounting base;

[0006] A screen mounting plate for fixing a screen, the screen mounting plate being rotatably connected to the mounting base about a first direction; one of the mounting base and the screen mounting plate is provided with a receiving cavity, and the other is provided with a mounting cavity along a second direction corresponding to the position of the receiving cavity;

[0007] An adjustment assembly includes a locking lever movably disposed within the receiving cavity along the second direction; when the locking lever is in a first position, at least a portion of the locking lever is inserted into the mounting cavity to fix the screen mounting plate and the mounting base to each other; when the locking lever is in a second position, the locking lever is located outside the mounting cavity to allow the screen mounting plate to rotate relative to the mounting base.

[0008] Furthermore, the locking rod includes an inclined surface facing the mounting cavity, and the adjustment assembly further includes an unlocking key, which is movably disposed in the receiving cavity and abuts against the inclined surface;

[0009] When the unlocking key moves relative to the receiving cavity, it pushes against the inclined surface, thereby causing the locking rod to move along the second direction.

[0010] Furthermore, the locking rod includes a main body, a mating part connected to the main body, and a plug-in part connected to the side of the main body near the mounting cavity. The mating part and the main body are arranged in a direction perpendicular to the second direction. The mating part has the inclined surface on the side facing the mounting cavity.

[0011] When the locking rod is in the first position, the plug is inserted into the mounting cavity; when the locking rod is in the second position, the plug is located outside the mounting cavity.

[0012] Furthermore, the main body is provided with limiting portions on both sides along a direction perpendicular to the second direction; the inner wall of the receiving cavity is provided with a groove that cooperates with the limiting portions, and the limiting portions are slidably disposed in the grooves.

[0013] Furthermore, the unlocking button has an inclined surface on the side near the locking bar that is adapted to the inclined surface, and the inclined surface abuts against the inclined surface.

[0014] Furthermore, the adjustment assembly also includes an elastic element disposed within the receiving cavity. One end of the elastic element abuts against the side of the locking rod away from the mounting cavity, and the other end abuts against the inner wall of the receiving cavity. When the locking rod is in the second position, the elastic element is in a compressed state.

[0015] Furthermore, the mounting cavity includes a plurality of recesses, which are arranged in a direction perpendicular to the first direction; when the locking rod is in the first position, the locking rod is inserted into any of the recesses.

[0016] Furthermore, the mounting cavity includes an opening and a bottom surface opposite to the opening. When the locking rod is in the first position, the locking rod extends into the mounting cavity from the opening. The bottom surface is arc-shaped, and the depth of the recesses on both sides of the bottom surface is less than the depth of the recess in the middle of the bottom surface.

[0017] Furthermore, the bracket also includes a pivot bolt; the mounting base includes a locking rod bracket, the locking rod bracket is provided with a mating groove, and the screen mounting plate is rotatably disposed in the mating groove; the pivot bolt passes through the side wall of the mating groove along the second direction.

[0018] This application provides a motor vehicle, including a vehicle body and a display device as described in any of the above embodiments, the display device being disposed on the vehicle body.

[0019] The display device provided in this application includes a bracket, an adjustment assembly, and a screen mounting plate for fixing a screen. The bracket includes a mounting base. The screen mounting plate is rotatably connected to the mounting base about a first direction. One of the mounting base and the screen mounting plate is provided with a receiving cavity, and the other is provided with a mounting cavity corresponding to the receiving cavity along a second direction. The adjustment assembly includes a locking lever, which is movably disposed within the receiving cavity along the second direction. When the locking lever is in the first position, at least a portion of the locking lever is inserted into the mounting cavity to fix the screen mounting plate and the mounting base to each other. When the locking lever is in the second position, the locking lever is located outside the mounting cavity, allowing the screen mounting plate to rotate relative to the mounting base. Thus, the rotation and fixing of the screen mounting plate can be achieved by adjusting the locking lever, so that the screen can face the user, facilitating the user's recognition of icons or text, simplifying user operation, and improving the user experience.

[0035] This application provides a display device and a motor vehicle. The display device and motor vehicle of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0036] This application provides a motor vehicle, including a vehicle body and a display device. The motor vehicle can be an automobile, including but not limited to gasoline-powered vehicles and new energy vehicles. The display device is disposed on the vehicle body. In some optional embodiments, the vehicle body includes front seats and a dashboard. It is understood that the front seats can be a driver's seat and a front passenger seat. The dashboard is disposed at the front end of the front seats, and the display device is disposed on the dashboard. The display device can be disposed in the center of the dashboard, specifically between the driver's and front passenger seats. It can also be disposed near the driver's or front passenger seat; this application does not impose any limitations.

[0037] See Figures 1 to 9As shown, this application provides a display device 10, including a bracket 11, an adjustment assembly 12, and a screen mounting plate 13. The display device 10 can be used to adjust the screen angle of devices such as in-vehicle screens, mobile phones, and tablets, and can also be used to adjust the screen angle of other devices. The bracket 11 supports the display device 10. The bracket 11 includes a mounting base 14. When the display device 10 is used in a motor vehicle, the mounting base 14 can be fixedly connected to the vehicle body. The fixing method can be bolt connection, snap-fit, etc., and this application is not limited to these methods. The screen mounting plate 13 is used to fix the screen, which is not limited to in-vehicle screens but can also refer to devices such as mobile phones and tablets. When the display device 10 is used in a motor vehicle, the screen can refer to a central control screen. The screen can be snapped into the screen mounting plate 13. The screen mounting plate 13 is rotatably connected to the mounting base 14 in a first direction. The screen mounting plate 13 can be fixed to the vehicle body via the mounting base 14. It is understood that there is a connecting surface between the screen mounting plate 13 and the mounting base 14. The connecting surface includes length and width, and the length of the connecting surface is greater than or equal to the width. The first direction can refer to the width direction X of the connecting surface (which can be understood as the yaw axis), the length direction Y of the connecting surface (which can be understood as the pitch axis), or the thickness direction Z of the screen mounting plate 13 (which can be understood as the roll axis). Of course, the first direction can also refer to the vertical or horizontal direction, and this application does not limit it. When the first direction is the width direction X of the connecting surface, the screen mounting plate 13 can swing horizontally relative to the mounting base 14 around the first direction; when the first direction is the length direction Y of the connecting surface, the screen mounting plate 13 can pitch relative to the mounting base 14 around the first direction; when the first direction is the thickness direction Z of the screen mounting plate 13, the screen mounting plate 13 can tilt relative to the mounting base 14 around the first direction. One of the mounting base 14 and the screen mounting plate 13 is provided with a receiving cavity 16, and the other is provided with a mounting cavity 17 corresponding to the position of the receiving cavity 16 along the second direction. It is understandable that the mounting base 14 may have a receiving cavity 16, and the screen mounting plate 13 may have a mounting cavity 17; alternatively, the screen mounting plate 13 may have a receiving cavity 16, and the mounting base 14 may have a mounting cavity 17. The mounting cavity 17 corresponds to the position of the receiving cavity 16 along a second direction. The second direction may be located on a plane perpendicular to the first direction, or it may not be perpendicular to the first direction. In the illustrated embodiment, the first direction is the width direction X of the connecting surface, and the second direction is the direction perpendicular to the connecting surface. The mounting base 14 has a receiving cavity 16, and the screen mounting plate 13 has a mounting cavity 17. The example described is that the screen mounting plate 13 is rotatably connected to the mounting base 14 about the width direction X.

[0038] The adjusting assembly 12 includes a locking rod 18, which is movably disposed within the receiving cavity 16 along a second direction. The locking rod 18 can be adjusted automatically or manually. Specifically, the locking rod 18 can be moved along the second direction by a micro-cylinder or manually. Figure 6 and Figure 8 As shown, when the locking lever 18 is in the first position, at least a portion of the locking lever 18 is inserted into the mounting cavity 17, thereby fixing the screen mounting plate 13 and the mounting base 14 to each other. Figure 9 As shown, when the locking lever 18 is in the second position, it is located outside the mounting cavity 17, allowing the screen mounting plate 13 to rotate relative to the mounting base 14. When the locking lever 18 switches from the first position to the second position, it disengages from the mounting cavity 17, allowing the screen mounting plate 13 to rotate relative to the mounting base 14. This allows the screen mounting plate 13 to be rotated to a suitable angle, enabling the user to see the icons or text displayed on the screen more clearly. When rotated to the appropriate position, the locking lever 18 switches from the second position to the first position, extending into the mounting cavity 17 to fix the screen mounting plate 13 and the mounting base 14 together.

[0039] In this way, the screen mounting plate 13 can be rotated and fixed by adjusting the locking lever 18, so that the screen can face the user, making it easier for the user to recognize icons or text. Even in strong sunlight, the icons and text on the screen are clearly visible, resulting in a better user experience and easier operation. When the display device 10 is used in a motor vehicle, the driver's and passenger's viewpoints can be switched by adjusting the display device 10, allowing the screen to face either the driver or passenger, facilitating operation and improving driving safety.

[0040] See Figures 7 to 9As shown, in some optional embodiments, the locking lever 18 includes an inclined surface 19 facing the mounting cavity 17. It is understood that the inclined surface 19 is located on the side of the locking lever 18 facing the mounting cavity 17. The adjustment assembly 12 also includes an unlocking button 20, which is movably disposed in the receiving cavity 16 and abuts against the inclined surface 19. In this embodiment, the unlocking button 20 includes a pressing portion 21 and an abutting portion 22, with the abutting portion 22 abutting against the inclined surface 19. The unlocking button 20 can be force-bearing via the pressing portion 21 and is movably disposed in the receiving cavity 16. The pressing portion 21 and the abutting portion 22 can be cuboid, cylindrical, or other shapes, and this application is not limited thereto. Optionally, the unlocking button 20 can be disposed on the top of the screen mounting plate 13 or the adjustment bracket 11 to facilitate the pressing force on the unlocking button 20 and the operation of the adjustment assembly 12. Optionally, the unlocking button 20 has an inclined surface 23 adapted to the inclined surface 19 on the side near the locking rod 18, and the inclined surface 23 abuts against the inclined surface 19. The inclination angle of the inclined surface 23 is the same as the inclination angle of the inclined surface 19. It is understood that the abutting part 22 has an inclined surface 23 adapted to the inclined surface 19. This arrangement increases the contact area between the unlocking button 20 and the inclined surface 19, reduces the pressure on the inclined surface 19, improves the service life of the locking rod 18, and allows the unlocking button 20 to slide on the inclined surface 19, facilitating relative movement between the locking rod 18 and the unlocking button 20. When the unlocking button 20 moves relative to the receiving cavity 16, it pushes against the inclined surface 19, thereby driving the locking rod 18 to move in the second direction. The movement method is simple and highly reliable. In this embodiment, when the unlocking button 20 moves relative to the receiving cavity 16 in the first direction, it pushes against the inclined surface 19, thereby driving the locking rod 18 to move in the second direction. In this way, the unlock button 20 can be pressed or pulled manually or automatically to move the locking lever 18, thereby rotating and fixing the screen mounting plate 13 so that the screen can face the user and improve the user experience.

[0041] In this embodiment, the inclined surface 19 is disposed at the top of the locking bar 18. In other embodiments, the inclined surface 19 may also be disposed on other sides of the locking bar 18. It is understood that, in conjunction with... Figure 6 and Figure 7 As shown, in the initial state, the locking lever 18 is in the first position, that is, at least a portion of the locking lever 18 is inserted into the mounting cavity 17, so that the screen mounting plate 13 and the mounting base 14 are fixed to each other. Figure 8 and Figure 9 As shown, when it is necessary to rotate the screen mounting plate 13, press the unlock button 20. During the movement of the unlock button 20, it abuts against the inclined surface 19 of the locking rod 18, causing the locking rod 18 to move until it moves to the second position, that is, the locking rod 18 is located outside the mounting cavity 17, so that the screen mounting plate 13 can rotate relative to the mounting base 14.

[0042] In some optional embodiments, the locking lever 18 includes a main body 24, a mating part 25 connected to the main body 24, and a plug-in part 26 connected to the side of the main body 24 near the mounting cavity 17. The plug-in part 26 and the main body 24 can be arranged along a first direction. The mating part 25 and the main body 24 are arranged in a direction perpendicular to a second direction, and the mating part 25 has a slope 19 on the side facing the mounting cavity 17. The slope 19 can be inclined from the main body 24 in a direction perpendicular to the second direction towards the side away from the mounting cavity 17. It is understood that the slope 19 is provided on the main body 24. When the locking lever 18 is in the first position, the plug-in part 26 is inserted into the mounting cavity 17; when the locking lever 18 is in the second position, the plug-in part 26 is located outside the mounting cavity 17. When the unlock button 20 moves relative to the receiving cavity 16, it pushes against the inclined surface 19 of the mating part 25, causing the locking lever 18 to move in the second direction, so that the locking lever 18 switches from the first position to the second position. The insertion part 26 disengages from the mounting cavity 17. At this time, the screen mounting plate 13 can rotate relative to the mounting base 14, allowing the screen mounting plate 13 to be rotated to a suitable angle position so that the user can see the icons or text displayed on the screen more clearly. When rotated to the suitable position, the locking lever 18 switches from the second position to the first position, and the insertion part 26 extends into the mounting cavity 17, so that the screen mounting plate 13 and the mounting base 14 are fixed to each other. In this way, the unlock button 20 can be moved manually or automatically by pressing or pulling, which moves the locking lever 18, so that the insertion part 26 can be inserted into the mounting cavity 17 or located outside the mounting cavity 17. This movement method is simple and highly reliable.

[0043] In some alternative embodiments, the main body 24 is provided with limiting portions 27 on both sides along a direction perpendicular to the second direction (see...). Figure 5 (As shown). The shape of the limiting part 27 can be cuboid, wing-shaped, etc., and this application does not impose any limitations. The inner wall of the receiving cavity 16 is provided with a groove 28 that mates with the limiting part 27 (see...). Figure 5 As shown, the limiting part 27 is slidably disposed within the groove 28. This arrangement restricts the position of the locking rod 18, so that the locking rod 18 can be confined within the groove 28 and can only move in the second direction, thus making the insertion part 26 more accurately inserted into the mounting cavity 17.

[0044] In some optional embodiments, the mounting cavity 17 includes a plurality of recesses 29 arranged in a direction perpendicular to the first direction. The number of recesses 29 can be two, three, four, etc. In this embodiment, the recesses 29 are arranged in a direction perpendicular to both the first and second directions. The recesses 29 can be arranged horizontally or vertically. When the locking rod 18 is in the first position, the locking rod 18 is inserted into any of the recesses 29. The locking rod 18 can be engaged within the recesses 29 to improve the limiting effect of the recesses 29 on the locking rod 18. Taking three recesses 29 as an example, the recesses 29 include a first recess 29, a second recess 29, and a third recess 29. When the locking rod 18 is in the first position, the locking rod 18 can be inserted into the first, second, or third recess 29. When the locking lever 18 is inserted into different recesses 29, the rotation angle of the screen mounting plate 13 relative to the mounting base 14 is different. This arrangement allows the screen mounting plate 13 to be fixed within a set angle, facilitating user operation.

[0045] In some optional embodiments, the mounting cavity 17 includes an opening 30 and a bottom surface 31 opposite to the opening 30. When the locking rod 18 is in a first position, the locking rod 18 extends into the mounting cavity 17 through the opening 30. When the locking rod 18 is in the first position, it may abut against the bottom surface 31 or be at a certain distance from it. The bottom surface 31 is arc-shaped, and the depth of the recesses 29 on both sides of the bottom surface 31 is less than the depth of the recess 29 located in the middle of the bottom surface 31. It is understood that the recesses 29 on both sides of the bottom surface 31 can refer to the recesses 29 located on both sides of the bottom surface 31 along a direction perpendicular to the first direction. This arrangement ensures that when the screen mounting plate 13 rotates relative to the mounting base 14 to any angle position, the opening 30 of any recess 29 can be aligned with the locking rod 18, thus facilitating the insertion of the locking rod 18 into the mounting cavity 17 along the second direction.

[0046] In some optional embodiments, the adjusting assembly 12 further includes an elastic element 32, which may be a spring, a sheet, or a similar structure. The elastic element 32 is disposed within the receiving cavity 16, with one end abutting against the side of the locking rod 18 away from the mounting cavity 17, and the other end abutting against the inner wall of the receiving cavity 16. It is understood that this abutment is not limited to one end of the elastic element 32 pressing against the side of the locking rod 18 away from the mounting cavity 17; when the elastic element 32 is a spring, it can also be interpreted as one end of the elastic element 32 being sleeved on the side of the locking rod 18 away from the mounting cavity 17. When the locking rod 18 is in the second position, the elastic element 32 is in a compressed state. In this embodiment, the locking rod 18 and the elastic element 32 are arranged along a second direction, with one end of the elastic element 32 abutting against the side of the locking rod 18 away from the mounting cavity 17, and the other end abutting against the inner wall of the receiving cavity 16 arranged along the second direction. When the locking lever 18 is not subjected to external force, the elastic element 32 can drive the locking lever 18 to move, so that the locking lever 18 can switch from the second position to the first position, thereby fixing the screen mounting plate 13 to the mounting base 14. This saves operation steps and makes the operation of the user more convenient.

[0047] In this embodiment, when the screen mounting plate 13 needs to be rotated, the unlock button 20 is pressed, causing the unlock button 20 to move relative to the receiving cavity 16. During this process, the unlock button 20 pushes against the inclined surface 19 of the mating part 25, thereby driving the locking rod 18 to move along the second direction, so that the locking rod 18 switches from the first position to the second position, the insertion part 26 disengages from the cavity 29, and the elastic member 32 is in a compressed state. At this time, the screen mounting plate 13 can rotate relative to the mounting base 14. When the screen mounting plate 13 rotates to a suitable angle position, the unlock button 20 is released, so that the locking rod 18 switches from the second position to the first position under the push of the elastic member 32, and the insertion part 26 extends into the mounting cavity 17, so that the screen mounting plate 13 and the mounting base 14 are fixed to each other. In this way, the screen mounting plate 13 can be rotated and fixed by manually pressing the unlock button 20 to drive the locking rod 18. This movement method is simple and highly reliable.

[0048] See you again Figure 5 and Figure 6As shown, in some optional embodiments, the bracket 11 further includes a pivot bolt 33. The number of pivot bolts 33 can be two. The mounting base 14 includes a locking rod bracket 34, which has a mating groove 35. The screen mounting plate 13 is rotatably disposed within the mating groove 35. In this embodiment, the screen mounting plate 13 includes a screen back cover plate 36 and a screen rotation bracket 37. The screen is fixedly mounted on the screen back cover plate 36, and the screen rotation bracket 37 is fixed to the side of the screen back cover plate 36 away from the screen, wherein the fixing method can be bolt fixing. The screen rotation bracket 37 is rotatably disposed within the mating groove 35. The side of the screen rotation bracket 37 facing the mating groove 35 can be arc-shaped, which facilitates the rotation of the screen mounting plate 13 relative to the mounting base 14. The pivot bolt 33 passes through the sidewall of the mating groove 35 along a second direction. The pivot bolt 33 can pass through both the mating groove 35 and the sidewall of the screen rotation bracket 37 along the second direction. The swivel bolt 33 allows the screen mounting plate 13 to be connected to the mounting base 14 while the screen mounting plate 13 can rotate relative to the mounting base 14. This design is simple and saves on parts.

[0049] In some optional embodiments, the mounting base 14 further includes a support base 38 for fixing to an external structure. When the display device 10 is applied to a motor vehicle, the support base 38 is fixed to the vehicle body. The support base 38 is located on the side of the locking rod bracket 34 away from the screen mounting plate 13. The locking rod bracket 34 and the support base 38 may together form a receiving cavity 16 or a mounting cavity 17. When the locking rod bracket 34 and the support base 38 together form the receiving cavity 16, the elastic member 32 can abut against the support base 38. Alternatively, the locking rod bracket 34 itself may form the receiving cavity 16 or the mounting cavity 17.

[0050] See Figure 5As shown, in some optional embodiments, the support base 38 includes a first support base 42, a second support base 43, and a third support base 44, with the second support base 43 located between the first support base 42 and the third support base 44 along a first direction. The first support base 42 and the third support base 44 can be snapped onto the second support base 43, thus fixing the three together. A pivot bolt 33 can be sequentially inserted along a second direction through the sidewall of the second support base 43, the mating groove 35, and the sidewall of the screen rotation bracket 37 to fix the second support base 43 to the locking rod bracket 34. There is a gap between the first support base 42 and the second support base 43. The screen includes a wire 47, which can be a power cord or a data cable. The wire 47 can extend outward through the gap between the first support base 42 and the second support base 43, thus making more rational use of space, a more compact layout, and a more regular appearance. In this embodiment, the first support base 42 includes a mounting portion 45 and a blocking portion 46. The mounting portion 45 is fixedly connected to the second support base 43, and the blocking portion 46 extends from the mounting portion 45 along a first direction. The locking rod bracket 34 and the blocking portion 46 together form a receiving cavity 16 or a mounting cavity 17. When the locking rod bracket 34 and the blocking portion 46 together form the receiving cavity 16, the elastic member 32 can abut against the blocking portion 46.

[0051] In some optional embodiments, the second support base 43 includes a reinforcing portion 48 extending along a first direction, with ear plates 49 at both ends of the reinforcing portion 48 along the first direction, which mate with the mating groove 35.
