[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0049] Embodiment 1

[0050] See also Figure 1 , Figure 2 and Figure 8 As shown, the present application provides a display device, which includes: a housing 100 , a display screen 200 , a decorative panel 300 and a switching mechanism 400 .

[0051] The housing 100 is surrounded to form a switching space 110 and is provided with a display window 101. The display window 101 is a position for viewing. When the display screen 200 is switched to the display window 101, the display screen 200 can be viewed. When the decorative panel 300 is switched to the display window 101, the decorative panel 300 can be viewed. The housing 100 mainly protects the display screen 200 and the decorative panel 300. The housing 100 can be made of metal or non-metal. For example, the housing 100 can be an aluminum shell or an alloy shell, or a plastic shell.

[0052] The display screen 200 is disposed in the switching space 110 and is used to display the external scene of the vehicle. By displaying the external scene of the vehicle, the driver can observe the situation of the visual blind spot.

[0053] The decorative panel 300 is arranged in the switching space 110 and is used to decorate the vehicle. The decorative panel 300 is used to increase the aesthetics of the vehicle's interior. Patterns and the like can be arranged on the decorative panel 300. Usually, the color of the decorative panel 300 is consistent with the color of the display window 101, and the overall look is more coordinated.

[0054] The switching mechanism 400 is disposed in the switching space 110, and at least one of the display screen 200 and the decorative panel 300 is connected to the switching mechanism 400, so that one of the display screen 200 and the decorative panel 300 is switched to be displayed in the display window 101 under the driving of the switching mechanism 400. It should be noted that the switching mechanism 400 may only drive the display screen 200 to switch, or only drive the decorative panel 300 to switch, or may drive the display screen 200 and the decorative panel 300 separately.

[0055] The switching mechanism 400 drives the display screen 200 and the decorative panel 300 to switch in a variety of ways. The display screen 200 and the decorative panel 300 can be switched in and out by pulling, pulling the display screen 200 to the display window 101, and pushing the decorative panel 300 away from the display window 101. Alternatively, the display screen 200 and the decorative panel 300 can be switched alternately by rotating, rotating the display screen 200 to the display window 101, and rotating the decorative panel 300 away from the display window 101.

[0056] In this embodiment, the display screen 200 can display the external scene of the vehicle. The switching between the display screen 200 and the decorative panel 300 can be controlled by the switching mechanism 400. When the external scene of the vehicle needs to be displayed, the external scene of the vehicle is displayed on the display screen 200, ensuring that the driver can observe the blind spot through the display screen 200. Thereby reducing safety hazards and reducing the occurrence of accidents.

[0057] When the driver is driving a car, the A-pillar is located at the front side of the vehicle and plays a supporting role, which is very important for the driving safety of the car. However, the A-pillar will block the driver's line of sight, causing visual blind spots, which pose a great safety hazard to the normal driving of the vehicle. For this reason, a display device can be set at the A-pillar position.

[0058] In the present application, since the vehicle has a variety of different installation environments and the space is relatively small. In order to enable the display device to adapt to a variety of different installation environments, the display screen 200 is set to a flexible display screen 200, and the decorative panel 300 is set to a flexible decorative panel 300. The display screen 200 and the decorative panel 300 can both withstand a certain degree of bending, or even curling, so that it is easy to install, can make full use of the space, and adapt well to a relatively small space. The display screen 200 can be an OLED (Organic Light-Emitting Diode). The OLED display screen 200 is thinner, has high brightness, low power consumption, fast response, high clarity, good flexibility, and high luminous efficiency. In addition, the housing 100 can also be set to a different structure, such as a curved housing 100, to adapt to the installation environment of the vehicle.

[0059] In the present application, the display screen 200 and the decorative panel 300 can be switched respectively under the drive of the switching mechanism 400. When the switching mechanism 400 can drive the display screen 200 and the decorative panel 300 to switch, the positions of the display screen 200 and the decorative panel 300 include at least two situations.

[0060] The first setting situation is that the display screen 200 and the decorative plate 300 are arranged on the same side of the switching mechanism 400, that is, the display screen 200 and the decorative plate 300 are arranged on the same plane, the display screen 200 and the decorative plate 300 are connected, and the switching mechanism 400 drives the display screen 200 and the decorative plate 300 to switch to the display window 101 respectively; for example, one end of the display screen 200 is connected to the switching mechanism 400, and the other end of the display screen 200 is connected to the decorative plate 300, that is, the decorative plate 300 is located at a position where the display screen 200 is away from the switching mechanism 400. Usually, the initial state is that the decorative plate 300 is located in the display window 101. When it is necessary to switch to the display screen 200, the switching mechanism 400 pushes the display screen 200, the display screen 200 squeezes the decorative plate 300, and the decorative plate 300 moves in a direction away from the switching mechanism 400 until the display screen 200 is located in the display window 101. When it is necessary to switch to the decorative plate 300, the switching mechanism 400 pulls the display screen 200, and the decorative plate 300 moves with the display screen 200, thereby switching to the display window 101.

[0061] Alternatively, one end of the decorative plate 300 is connected to the switching mechanism 400, and the other end of the decorative plate 300 is connected to the display screen 200. The display screen 200 is located at a position of the decorative plate 300 away from the switching mechanism 400. When it is necessary to switch to the display screen 200, the switching mechanism 400 pushes the decorative plate 300, and the decorative plate 300 squeezes the display screen 200, so that the display screen 200 moves to the display window 101. When it is necessary to switch to the decorative plate 300, the switching mechanism 400 pulls or pushes the decorative plate 300, so that the decorative plate 300 moves to the display window 101.

[0062] It should be noted that the switching mechanism 400 is disposed at one end of the switching space 110 of the housing 100, and a retention space is formed on the side of the display window 101 away from the switching mechanism 400, and the retention space is used to accommodate the display screen 200 or the decorative plate 300. For example, when the switching mechanism 400 pushes the decorative plate 300, the display screen 200 moves to be retained in the retention space, or when the switching mechanism 400 pushes the display screen 200, the decorative plate 300 moves to be retained in the retention space. The display screen 200 or the decorative plate 300 can be rolled up and retracted in the retention space, which can save space.

[0063] The second arrangement is that the display screen 200 and the decorative plate 300 are overlapped and arranged on two sides of the switching mechanism 400, that is, the display screen 200 and the decorative plate 300 are stacked up and down. The display screen 200 and the decorative plate 300 are both connected to the switching mechanism 400, and the switching mechanism 400 drives the display screen 200 and the decorative plate 300 to switch to the display window 101 respectively.

[0064] For example, when the display screen 200 is displayed, the display screen 200 is pushed out and the decorative plate 300 is returned. When the decorative plate 300 needs to be displayed, the decorative plate 300 is pushed out and the display screen 200 is returned. Thus, when switching operations are performed, the moving directions of the display screen 200 and the decorative plate 300 are opposite.

[0065] See also Figure 2 and Figure 3 As shown, there is another configuration in which the decorative plate 300 is wound around the switching mechanism 400 on the basis of the overlap of the display screen 200 and the decorative plate 300, so that the decorative plate 300 forms an upper and lower layer, and one end of the display screen 200 is connected to the lower layer of the decorative plate 300. The upper layer of the decorative plate 300 is used to switch to the display window 101, and the lower layer of the decorative plate 300 is used to drive the display screen 200 to move.

[0066] In this application, the display screen 200 and the decorative plate 300 may contact each other and easily cause friction. In order to reduce the scratches of the display screen 200 caused by friction, an anti-scratch layer or a wear-resistant material such as a layer of silica gel may be provided on the surface of the display screen 200.

[0067] See also Figure 4 As shown, the switching method of the switching mechanism 400 in the present application is described below by way of example. The switching mechanism 400 includes a gear shaft 410 and a hinge 420. The hinge 420 is meshed with the gear shaft 410. The display screen 200 and the decorative panel 300 are connected to the hinge 420. The gear shaft 410 rotates to drive the display screen 200 and the decorative panel 300 to switch. The hinge 420 is usually a flexible hinge 420. The gear shaft 410 is disposed on one side of the switching space 110. The rotation of the gear shaft 410 drives the hinge 420 to move. Since the display screen 200 is connected to the hinge 420, the movement of the hinge 420 drives the display screen 200 to move, or drives the decorative panel 300 to move.

[0068] For another example, the display screen 200 and the decorative panel 300 are arranged on opposite sides of the gear shaft 410. When the gear shaft 410 rotates in the forward direction, the hinge 420 moves to push the display screen 200 out, that is, to move in a direction away from the gear shaft 410. At the same time, the gear shaft 410 rotates in the forward direction, driving the decorative panel 300 to retract, that is, to move in a direction close to the gear shaft 410. In addition, when the gear shaft 410 rotates in the reverse direction, the hinge 420 drives the display screen 200 to retract, that is, to move in a direction close to the gear shaft 410. At the same time, the gear shaft 410 rotates in the reverse direction, driving the decorative panel 300 to be sent out, that is, to move in a direction away from the gear shaft 410. It can be seen that the switching of the display screen 200 and the decorative panel 300 can be controlled by the forward and reverse rotation of the gear shaft 410.

[0069] In order to increase the effect of the gear shaft 410 driving the hinge 420 to move, the gear shaft 410 includes a rotating shaft 411 and a toothed ring 412. The toothed ring 412 is sleeved on the radial side of the rotating shaft 411, and the hinge 420 is meshed with the toothed ring 412. In this way, the friction between the hinge 420 and the toothed ring 412 is greater, and the gear shaft 410 can well drive the hinge 420 to move. The toothed ring 412 can be fixed to the rotating shaft 411 by rivets or screws, or by welding.

[0070] Among them, a gear ring 412 is provided, and a gear ring 412 is provided at the middle position of the rotating shaft 411; the corresponding hinge 420 is also provided at the middle position, which can make the display screen 200 and the decorative panel 300 move more stably and avoid the cheap situation.

[0071] In addition, two toothed rings 412 are provided, and the two toothed rings 412 are respectively provided at the two ends of the rotating shaft 411. The two toothed rings 412 can be symmetrically arranged at the center point of the rotating shaft 411, so that the hinges 420 at both ends are also symmetrically arranged, which can make the display screen 200 and the decorative plate 300 move more smoothly and the forces at both ends are more balanced.

[0072] Furthermore, three gear rings 412 can also be provided, one is provided in the middle position of the rotating shaft 411, and one is provided at each end of the rotating shaft 411. The gear rings 412 at both ends are also symmetrically arranged with respect to the center of the rotating shaft 411, for a total of three gear rings 412, which increase the force-bearing positions of the display screen 200 and the decorative panel 300, and drive the display screen 200 and the decorative panel 300 to move more stably.

[0073] See also Figure 5 As shown, in addition to the above-mentioned setting mode of the switching mechanism 400, the present application also provides another setting mode, the switching mechanism 400 includes a reel 430 and a curling sheet 440, the curling sheet 440 is connected to the reel 430, and the curling sheet 440 can be wound around the reel 430, and as the reel 430 rotates, the curling sheet 440 bends at the position passing through the reel 430. The display screen 200 and the decorative plate 300 are respectively connected to the curling sheet 440; when the reel 430 rotates, the curling sheet 440 moves with the reel 430 to drive the display screen 200 and the decorative plate 300 to switch.

[0074] In order to ensure that the display screen 200 can display images smoothly, the display device also includes a flexible flat cable 600, which is externally connected to the display screen 200. The flexible flat cable 600 can more effectively achieve the contraction effect, adapt well to the rotation of the shaft 411, and keep the display screen 200 powered.

[0075] See also Figure 6 and Figure 7As shown, in order to prevent the decorative plate 300 from folding together, or the decorative plate 300 and the display screen 200 from being attached together, the display device further includes a separator 500, which is disposed in the switching space 110. The separator 500 and the inner wall surface of the housing 100 are spaced apart to form a guide groove 102, which extends to the display window 101, and the display screen 200 and the decorative plate 300 move along the extension direction of the guide groove 102. The separator 500 can separate the folded decorative plate 300 or the display screen 200, and the main separation method is that the guide groove 102 formed by the separator 500 and the inner wall surface of the housing 100 has a limited height, which can ensure that the decorative plate 300 or the display screen 200 of a single thickness is separated.

[0076] In addition, by providing the guide groove 102 , it is also possible to ensure that the decorative panel 300 and the display screen 200 move in the correct direction and quickly switch to the position of the display window 101 .

[0077] Furthermore, the partition block 500 can be integrally provided with the housing 100, which is convenient for processing and manufacturing. The partition block 500 is thicker at one end close to the switching mechanism 400, so that the housing 100 can be supported to form a space large enough to accommodate the switching mechanism 400. The thickness of the partition block 500 gradually becomes thinner in the direction gradually approaching the display window 101, and the partition block 500 and the inner wall surface of the housing 100 form two upper and lower guide grooves 102, one of which can be provided with the display screen 200, and the other guide groove 102 can be provided with the decorative plate 300, so that the display screen 200 and the decorative plate 300 can be well separated, reducing the frictional contact between the two. The edges of the display screen 200 are sealed with silicone to protect the edges of the display screen 200 and reduce edge damage caused by long-term friction.

[0078] In the present application, in addition to the switching methods of the display screen 200 and the decorative panel 300 mentioned above, two switching methods are also provided. One of the switching methods is that the display screen 200 is fixed in the switching space 110, the display surface of the display screen 200 is set corresponding to the display window 101, the decorative panel 300 is connected to the switching mechanism 400, and the switching mechanism 400 drives the decorative panel 300 to switch between the position of the display window 101 and the position away from the display window 101, wherein the decorative panel 300 covers the display screen 200 when it is located at the position of the display window 101; therefore, it can be understood that the display screen 200 is fixed at the position of the display window 101 and does not move, and the switching mechanism 400 only drives the decorative panel 300 to complete the switching. When the decorative panel 300 needs to be displayed, the switching mechanism 400 drives the decorative panel 300 to move, and the decorative panel 300 moves to the display window 101 to cover the display screen 200. When the display screen 200 is needed, the switching mechanism 400 drives the decorative plate 300 to move in the reverse direction and leave the display window 101, and the display screen 200 is exposed to display the picture.

[0079] Another switching method is that the decorative plate 300 is fixed in the switching space 110, the decorative plate 300 is set corresponding to the display window 101, the display screen 200 is connected to the switching mechanism 400, and the switching mechanism 400 drives the display screen 200 to switch between the position of the display window 101 and the position away from the display window 101, wherein the display screen 200 covers the decorative plate 300 when it is located at the position of the display window 101. Similarly, it can be understood that the decorative plate 300 is fixed at the position of the display window 101 and does not move, and the switching mechanism 400 only drives the display screen 200 to complete the switching. When the display screen 200 is needed, the switching mechanism 400 drives the display screen 200 to move, and the display screen 200 moves to the display window 101, covering the decorative plate 300, and completing the picture display. When the decorative plate 300 needs to be displayed, the switching mechanism 400 drives the display screen 200 to move in the opposite direction, leaving the display window 101, and the decorative plate 300 is exposed.

[0080] In the present application, the display device includes a micro motor, and the micro motor can be used to drive the rotating shaft 411 to rotate. Under the space limitation of the vehicle, a hyperbolic gear set can be selected for driving.

[0081] Embodiment 2

[0082] See also Fig. 9 As shown, the present application also provides a display method, which is applied to the display device as described above, and the display method includes:

[0083] Step S10, identifying the running state of the vehicle, and generating a switching signal according to the running state of the vehicle; the initial state may be assumed that the decorative panel 300 is in a released state, that is, the decorative panel 300 is located in the display window 101. When the vehicle starts to start, the display device is also started synchronously, or it is understood that the display device is in a pre-started state. The central control system identifies the running state of the vehicle, whether it is turning or driving at a high speed. Different switching signals are generated according to different running states of the vehicle.

[0084] Step S20, according to the switching signal, the switching mechanism 400 is controlled to start, so as to drive one of the display screen 200 and the decorative panel 300 to switch to the display window 101. When it is necessary to observe the image in the blind area, the display screen 200 can be switched to the display window 101, and when it is not necessary to observe the image in the blind area, the decorative panel 300 can be switched to the display window 101.

[0085] The display screen 200 can display the external scene of the vehicle. The switching between the display screen 200 and the decorative panel 300 can be controlled by the switching mechanism 400. When the external scene of the vehicle needs to be displayed, the external scene of the vehicle is displayed on the display screen 200, ensuring that the driver can observe the blind spot through the display screen 200. Thereby reducing safety hazards and reducing the occurrence of accidents.

[0086] Before step S10, there is step S01, the vehicle is started, and the initial state of the display device is that the decorative panel 300 is released to the display window 101, that is, under normal circumstances, the display screen 200 is in a retracted state, and the decorative panel 300 is in a released state.

[0087] See also Fig.10 As shown, in the present application, the steps of identifying the running state of the vehicle and generating a switching signal according to the running state of the vehicle include:

[0088] Step S11, when it is identified that the vehicle is in a turning state, a first switching signal is generated; when the vehicle is turning, there is a visual blind spot in the direction of the turn, especially at the position of the A-pillar of the vehicle. If it is identified that the vehicle is in a turning state, a first switching signal is generated to control the switching of the display screen 200. The process of identifying that the vehicle is in a turning state may be to identify whether the turn signal is on, or to identify the steering angle of the wheel, or the turning angle of the steering wheel. Alternatively, the driver may manually issue a command.

[0089] Step S12, when it is identified that the vehicle speed is greater than the preset speed, a second switching signal is generated; the vehicle speed is greater than the preset speed, indicating that the vehicle is traveling at a faster speed, indicating that the field of vision is relatively wide, and the visual blind area is relatively small, and the display screen 200 can be retracted. For example, the preset speed is 60Km / h, 70Km / h, 80Km / h, etc. The preset speed can be adjusted as needed.

[0090] Step S13, the vehicle is in a non-moving state, which can be understood as the vehicle is not in a turning state and the speed is not greater than a preset speed.

[0091] In step S30 , the display device is in a dormant state or restored to an initial state, that is, the switching mechanism 400 stops operating and maintains the current display state, that is, maintains the current display screen 200 in the display window 101 , or releases the decorative panel 300 to the position of the display window 101 .

[0092] The step of controlling the switching mechanism 400 to start according to the switching signal to drive one of the display screen 200 and the decorative panel 300 to switch to the display window 101 includes:

[0093] Step S21, according to the first switching signal, the switching mechanism 400 is controlled to start, and the display screen 200 is switched to the display window 101; after receiving the first switching signal, the switching mechanism 400 starts to switch the display screen 200. After the vehicle ends the current state, that is, the turning state, the switching mechanism 400 drives the display screen 200 to move in the reverse direction, the display screen 200 is folded, and the decorative panel 300 is released and sent out.

[0094] Step S22, according to the second switching signal, the switching mechanism 400 is controlled to start, and the decorative panel 300 is switched to the display window 101. After receiving the second switching signal, the switching mechanism 400 starts, switches the decorative panel 300 to the display window 101, and releases the decorative panel 300 to the display window 101.

[0095] In addition, in the present application, in order to improve the service life of the display screen 200, the number of rotations of the micro motor in the switching mechanism 400 is controlled to prevent the display screen 200 from being wound around the rotating shaft 411. In other words, the display screen 200 in the present application will not be wound around the rotating shaft 411. Similarly, the decorative plate 300 can be prevented from being wound around the rotating shaft 411 by controlling the number of rotations of the micro motor. For example, a flexible connector wound around the rotating shaft 411 can be provided, one end of the flexible connector is connected to the decorative plate 300, and the other end is connected to the display screen 200. The micro motor controls the flexible connector to rotate on the rotating shaft 411, thereby preventing the decorative plate 300 and the display screen 200 from being wound and bent.
