[0048] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and techniques are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of regional structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0049] In related technologies, manufacturers are pursuing larger display screens to enhance the user experience. However, large display screens are not suitable for all vehicle usage scenarios. For example, when viewing the displayed content is not necessary, large display screens have technical issues such as high energy consumption and the tendency to distract the driver.

[0050] In view of this, an embodiment of the present application provides a control method for a display device, a vehicle, and a display device. By setting a lifting component to control the position of the display panel, the display panel can be completely located in the storage compartment, partially located in the storage compartment, or completely located outside the storage compartment according to user needs, so as to meet multi-scenario applications and improve user experience.

[0051] The specific structures and processes of the display device, vehicle, and display device control method provided in each embodiment of the present application are described below in conjunction with the accompanying drawings.

[0052] First embodiment

[0053] Figure 1 A schematic structural diagram of a display device 100 provided in the first embodiment of the present application is shown.

[0054] like Figure 1 As shown, the first embodiment of the present application provides a display device 100, including: a display panel 200, a storage compartment 300 and a lifting assembly 400; the storage compartment 300 is used to accommodate the display panel 200, and the lifting assembly 400 is connected to the display panel 200, and is used to control the display panel 200 to move along the depth direction of the storage compartment 300, so as to adjust the area of ​​the working display area of ​​the display panel 200, thereby enabling the display device 100 to present multiple display modes.

[0055] The display panel 200 and the lifting assembly 400 can be fastened together by screws.

[0056] The display device 100 of the present application can be used in automobiles. Specifically, depending on different usage scenarios, the display panel 200 is controlled to be located outside the storage compartment 300, as well as the display area outside the storage compartment 300. When the user does not need to display the screen, such as when there is no one in the car and the engine of the vehicle 500 is in a stopped state, the display device 100 is completely located in the storage compartment 300, which can save space in the car and avoid problems such as sunlight aging. When the user does not need to display the screen, a variety of display modes are presented according to the user's needs.

[0057] Exemplarily, the display modes include a first display mode, a second display mode, a third display mode, and a fourth display mode. In the first display mode, the area of ​​the display panel 200 exposed from the storage compartment 300 is minimized, i.e., the display screen is minimized. This display mode is suitable for displaying only simple text. Specifically, while the driver is driving the vehicle 500, the display panel 200 displays only simple text information, such as weather information and time information. In the second display mode, the area of ​​the display panel 200 exposed from the storage compartment 300 is larger than in the first display mode and smaller than in the third display mode. The second display mode is suitable for displaying partial vehicle 500 information, such as the remaining battery life of an electric vehicle 500, and can also be combined with image information, such as a music player. The third display mode is suitable for scenarios requiring large-scale image display, such as navigation screens, reversing images, radar information, etc. In the fourth display mode, the display panel 200 is fully extended from the storage compartment 300, displaying the full screen of the display panel 200, suitable for entertainment mode.

[0058] This application does not specifically limit the number of display modes.

[0059] The lifting assembly 400 includes:

[0060] The shift structure 10 includes a plurality of sequentially connected shift members 11. Each shift member 11 corresponds one-to-one to the working display area, that is, one-to-one to the display mode. That is, the number of shift members 11 is the same as the number of display modes. For example, when there are four shift members 11, the display device 100 includes four display modes. The four shift members 11 can be arranged sequentially along the depth direction of the storage compartment 300; the four shift members 11 can also be connected end-to-end, for example, arranged in a ring around the city.

[0061] The locking structure 20 is coupled to the shift member 11. It is used to secure the shift member 11, ensuring stable display in all display modes of the display device 100. When a particular display mode is displayed, the locking structure 20 engages and locks the shift member 11 corresponding to that display mode, preventing the shift member 11 from shifting in the depth direction of the storage compartment 300 due to gravity or the drive structure. This would prevent the display panel 200 exposed from the storage compartment 300 from shaking up and down. The locking structure 20 ensures stable display in all display modes.

[0062] The driving structure is connected to the gear structure 10 and is used to drive the gear structure 10 to move along the depth direction of the accommodating compartment 300.

[0063] Specifically, the driving structure can make the gear structure 10 move back and forth along the depth direction of the accommodating compartment 300, that is, drive the display panel 200 to move back and forth along the depth direction of the accommodating compartment 300, so as to realize the switching of different display modes.

[0064] In this embodiment, by providing a shift structure 10, a driving structure drives the shift structure 10 to move along the depth direction of the storage compartment 300, causing the locking structure 20 to engage with different shift members 11, thereby adjusting the display area of ​​the display panel 200 exposed within the storage compartment 300, thereby adapting the display device 100 to different usage scenarios. Compared to related technologies, in which the display area of ​​the display device 100 is fixed and relatively large, this application adjusts the display area of ​​the display panel 200 according to different usage scenarios, achieving display screens of different sizes corresponding to different usage scenarios, realizing intelligent display, and improving the user experience.

[0065] Figure 2 A schematic structural diagram of a first lifting assembly 400 provided in the first embodiment of the present application is shown;

[0066] Figure 3 A structural schematic diagram of the second lifting assembly provided in Example 1 of the present application is shown.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the locking structure 20 includes a locking rod 21, one end of which is fixedly connected to the bottom of the accommodating compartment 300; a limiting protrusion 211 is provided at the other end of the locking rod 21, and each shift member 11 is provided with a limiting groove 111 that cooperates with the limiting protrusion 211. The limiting protrusion 211 is snapped into the limiting groove 111 of the shift member 11 corresponding to the current working display area of ​​the display panel 200 to fix the current working display area of ​​the display panel 200. By providing the mutually cooperating limiting protrusion 211 and limiting groove 111, the display panel 200 exposed from the accommodating compartment 300 is prevented from shaking up and down, thereby achieving stable display in different display modes.

[0068] In other embodiments, the locking structure 20 also includes a limiting member (not shown in the accompanying drawings) that is detachably connected to the shift member 11, and a limiting groove 111 that cooperates with the limiting protrusion 211 is provided on the limiting member. The limiting protrusion 211 is inserted into the limiting groove 111 of the shift member 11 corresponding to the current working display area of ​​the display panel 200 to fix the current working display area of ​​the display panel 200.

[0069] In this embodiment, the stopper is a separate structure. When it cooperates with the locking rod 21, it prevents the force applied by the locking rod 21 from directly acting on the shift member 11, thereby extending the service life of the shift member 11. Moreover, if the stopper is damaged, there is no need to replace the shift member 11. Only the stopper connected to the shift member 11 needs to be replaced, which simplifies the maintenance procedure and reduces maintenance costs.

[0070] In some embodiments, the driving structure 30 includes a first driving structure 31 and a second driving structure 32 .

[0071] The first driving structure 31 is used to move the shift structure 10 toward the bottom of the accommodating compartment 300;

[0072] The second driving structure 32 is used to move the shift structure 10 in a direction away from the bottom of the accommodating compartment 300 .

[0073] It can be understood that the direction toward the bottom of the storage compartment 300 and the direction away from the bottom of the storage compartment 300 are different according to the opening direction of the storage compartment 300. Exemplarily, when the opening of the storage compartment 300 is downward, such as when the display device 100 is set on the roof of the vehicle, the first driving structure 31 provides an upward driving force for the display panel 200, and the second driving structure 32 provides a downward driving force for the display panel 200. When the opening of the storage compartment 300 is upward, the first driving structure 31 provides a downward driving force for the display panel 200, and the second driving structure 32 provides an upward driving force for the display panel 200. When the opening of the storage compartment 300 is to the left, the first driving structure 31 provides a rightward driving force for the display panel 200, and the second driving structure 32 provides a leftward driving force for the display panel 200. When the opening of the accommodating compartment 300 faces rightward, the first driving structure 31 provides a leftward driving force for the display panel 200 , and the second driving structure 32 provides a rightward driving force for the display panel 200 .

[0074] The first driving structure 31 provides a driving force for the display panel 200 to retract into the accommodating chamber 300 , and the second driving structure 32 provides a driving force for the display panel 200 to extend out of the accommodating chamber 300 , so that the display panel 200 can extend out of the accommodating chamber or retract into the accommodating chamber.

[0075] This application does not limit the specific positions of the first driving structure 31 and the second driving structure 32. Figure 2This is for illustrative purposes only.

[0076] In some embodiments, the first driving structure 31 includes a first driving motor 311 and a first traction structure 312 . One end of the first traction structure 312 is connected to the gear structure 10 , and the other end of the first traction structure 312 is connected to the first driving motor 311 .

[0077] The second driving structure 32 includes a second driving motor 321 and a second traction structure 322 , one end of the second traction structure 322 is connected to the gear structure 10 , and the other end of the second traction structure 322 is connected to the second driving motor 321 ; alternatively, the second driving structure 32 includes an elastic structure 323 .

[0078] When the first driving structure 31 is the first driving motor 311 and the first traction structure 312, and the second driving structure 32 is the second driving motor 321 and the second traction structure 322 (as shown in FIG. Figure 2 As shown in FIG3 , the first drive structure 31 provides the driving force for the display panel 200 to retract into the storage compartment 300, and the second drive structure 32 provides the driving force for the display panel 200 to extend out of the storage compartment 300. The motor rotates, causing the traction structure to pull the shift structure 10 to move along the depth direction of the storage compartment 300, thereby switching the limit groove 111 engaged with the locking rod 21, and then switching the shift member 11 engaged with the locking structure 20. Since the shift member 11 corresponds to the display mode in the present application, the motor rotates and pulls the traction structure to adjust the area of ​​the working display area of ​​the display panel 200 to realize arbitrary switching of the display mode.

[0079] When the first driving structure 31 is the first driving motor 311 and the first traction structure 312, and the second driving structure 32 is the elastic structure 323 (eg Figure 3 ), the first driving structure 31 provides a driving force for the display panel 200 to retract into the accommodating compartment 300, and the second driving structure 32 provides a driving force for the display panel 200 to extend out of the accommodating compartment 300.

[0080] Taking the upward-facing opening of the storage compartment 300 as an example, the second drive structure 32 is positioned above the shift structure 10. When the display panel 200 is fully extended from the storage compartment 300, the elastic structure 323 is at its original length, without being stretched or squeezed. When the display panel 200 is located within the storage compartment 300, the elastic structure 323 is stretched. When the user requires a larger display, the elastic structure 323 returns to its original length, and the contraction force driving the shift structure 10 upward pulls the portion of the display panel 200 in the storage compartment 300 out of the storage compartment 300, enabling a larger display. This, in other words, switches to a larger display mode.

[0081] The second drive structure 32 is positioned below the shift structure 10. When the display panel 200 is fully extended from the storage compartment 300, the elastic structure 323 is at its original length, without being stretched or squeezed. When the display panel 200 is located within the storage compartment 300, the elastic structure 323 is compressed. When the user requires a larger display, the elastic structure 323 returns to its original length from its compressed state, and the elongation force drives the shift structure 10 upward. This pulls the portion of the display panel 200 in the storage compartment 300 out of the storage compartment 300, enabling a larger display, i.e., switching to a larger display mode.

[0082] In this embodiment, the elastic structure 323 is used to replace the second driving structure 32 including the servo motor and the traction rope, which reduces the preparation cost and reduces the volume of the lifting assembly 400, saving space, making the display device 100 of the present application more practical.

[0083] In some embodiments, the shift structure 10 further includes a slider 12 , which is sleeved on the outside of the shift member 11 and fixedly connected to the shift member 11 , and the driving structure is connected to the shift member 11 via the slider 12 .

[0084] The lifting assembly 400 further includes a housing 40 which is sleeved on the outside of the shift structure 10 , the locking structure 20 and the driving structure, and has a slide rail 41 provided inside thereof so that the slider 12 can slide on the slide rail 41 .

[0085] Specifically, in this embodiment, the first drive structure 31 and the second drive structure 32 are connected to the slider 12 to apply force to the slider 12 along the depth direction of the storage compartment 300 to adjust the area of ​​the working display area of ​​the display panel 200 and switch the display mode. Compared to applying force directly to the shift structure 10, this embodiment distributes the external force to the slider 12, reducing the pressure at the force-bearing point of the shift structure 10, preventing damage to the shift structure 10, and extending the service life of the shift structure 10, thereby increasing the service life of the display device 100.

[0086] Figure 2 and Figure 3 The gear structure 10 is set inside the slider 12. Figure 2 This is merely an example, and the shift structure 10 may also be disposed outside the slider 12 . The positional relationship between the slider 12 and the shift structure 10 is not specifically limited.

[0087] The outer shell 40 wraps the gear structure 10, the locking structure 20 and the driving structure, and a slide rail 41 is provided on the inner side of the outer shell 40. The slider 12 is provided with protrusions on both sides of the slide rail 41 (not shown in the figure), and the protrusions are engaged with the slide rail 41 so that the slider 12 can slide on the slide rail 41.

[0088] The housing 40 prevents dust from entering the lifting assembly 400, preventing accumulation of dust that could cause the display panel 200 to jam along the depth of the storage compartment 300, thereby preventing lags during display mode switching. Slide rails 41 are provided inside the housing 40 to further reduce resistance to the display panel 200's movement, further enhancing the user experience.

[0089] Specifically, taking the upward opening of the storage compartment 300 as an example, if the area of ​​the working display area is increased, even if the gear structure 10 moves upward, the locking rod 21 should be engaged with the gear member 11 located below, and the second driving structure 32 first drives the slider 12 to move downward so that the limiting protrusion 211 moves out of the limiting groove 111, and the first driving mechanism drives the slider 12 to move upward so that the limiting protrusion 211 is engaged with the gear member 11 located below. It should be noted that during the above adjustment process, the angle of the gear member 11 needs to be adjusted to match the up and down movement of the slider 12 to achieve the change of gear. The adjustment of the angle of the gear member 11 can be achieved by arranging an additional motor, which will not be described in detail.

[0090] In some embodiments, reference Figure 1 and Figure 4 As shown, the lifting assembly 400 further includes a switch structure 50 located on the shifting member 11 for controlling the operation of the driving structure.

[0091] When switching display modes, the servo motor rotates, and the traction rope pulls the shift structure 10 to move. At this time, the locking rod 21 and the shift member 11 undergo relative displacement. The protrusion on the locking rod 21 moves from the groove on the shift member 11 corresponding to the initial display mode to the groove on the shift member 11 corresponding to the target display mode, and touches the switch structure 50. The switch structure 50 sends an electrical signal and transmits it to the servo motor. After receiving the corresponding electrical signal, the servo motor stops rotating, avoiding the servo motor from being in an operating state when it is no longer needed to provide driving force, thereby wasting energy. The locking structure 20 also resists the driving force generated by the servo motor, reducing the service life of the locking structure 20.

[0092] The switch structure 50 is preferably a mechanical micro switch or proximity sensor, integrated into the side or bottom of the shift member 11. When the servo motor needs to be activated, the driver can input a new display mode requirement (e.g., switching from "navigation mode" to "entertainment mode") through the vehicle's central control screen, physical buttons, or voice commands to re-activate the servo motor.

[0093] In this embodiment, by providing a shift structure 10, a driving structure drives the shift structure 10 to move along the depth direction of the storage compartment 300, so that the locking structure 20 engages with different shift members 11, and the display area of ​​the display panel 200 exposed in the storage compartment 300 is adjusted, so that the display device 100 is suitable for different usage scenarios. Compared with the related art, the display area of ​​the display device 100 is fixed and the display area is large. The present application adjusts the display area of ​​the display panel 200 according to different usage scenarios, realizing display images of different sizes corresponding to different usage scenarios, realizing intelligent display, and improving user experience. In addition, by providing a slider 12 and a housing 40 in this embodiment, on the one hand, external forces are dispersed to the slider 12, reducing the pressure at the force point of the shift structure 10, preventing damage to the shift structure 10, and extending the service life of the shift structure 10, thereby increasing the service life of the display device 100; on the other hand, dust is prevented from entering the lifting assembly 400, preventing a large amount of dust accumulation from causing the display panel 200 to move along the depth direction of the storage compartment 300 and causing jamming, that is, preventing jamming when switching between display modes, thereby ensuring user experience. In addition, a slide rail 41 is provided inside the housing 40 to further reduce the movement resistance of the display panel 200 and further improve the user experience.

[0094] Second embodiment

[0096] like Figure 5 As shown, the second embodiment of the present application provides a vehicle 500, including: a vehicle speed sensor 600, a gear lever position sensor 700 and the display device 100 provided in the first embodiment.

[0097] In this embodiment, by providing a display device 100 with a switchable display area in the vehicle 500, the user can switch the display mode according to different scenarios, thereby improving the user experience.

[0100] like Figure 6 As shown, the third embodiment of the present application provides a method for controlling a display device, wherein the display device is provided in the vehicle provided in the third embodiment, including:

[0101] Step S101: Acquire mode information.

[0102] Mode information includes manual mode information and automatic mode information. When the user manually switches the display mode, if the pressure parameter of the finger is detected, the mode information is considered to be manual mode information; if no pressure parameter is detected, the mode information is considered to be automatic mode information.

[0103] Step S102: Calculating the distance data of the shift structure moving along the depth direction of the accommodating compartment according to the mode information.

[0104] The gear structure includes a plurality of gear members connected in sequence, and the gear members correspond to the working display areas one by one.

[0105] Specifically, the preset working display area is determined according to the mode parameters, and the distance the gear structure needs to move is calculated based on the height difference between the current working display area and the preset working display area where the display panel extends out of the accommodating compartment, that is, the distance data of the gear structure moving along the depth direction of the accommodating compartment.

[0106] Step S103: Calculate the working parameters of the driving structure based on the distance data, including the moving direction and distance of the driving gear structure along the depth direction of the accommodating chamber, and drive the gear structure to move to drive the display panel to move to the target position along the depth direction of the accommodating chamber.

[0107] The locking structure cooperates with the shift member to fix the working display area of ​​the current display panel.

[0108] According to the distance data, the preset gear piece corresponding to the preset display mode is calculated and obtained, and the driving structure pulls the gear structure so that the locking structure and the preset gear piece are engaged to realize the display mode switching.

[0109] In this embodiment, mode information is obtained; based on the mode information, the distance data of the shift structure's movement along the depth direction of the storage compartment is calculated; based on the distance data, the operating parameters of the driving structure are calculated. The operating parameters include the movement direction and distance of the shift structure along the depth direction of the storage compartment, and the shift structure is driven to move, thereby driving the display panel to a target position along the depth direction of the storage compartment. This allows users to adjust the display area of ​​the display panel in different usage scenarios, thereby improving the user experience.

[0110] In some embodiments, step S102: calculating the distance data of the shift structure moving along the depth direction of the accommodating compartment according to the mode information, includes:

[0111] Step S1021: If the mode information indicates manual mode information, then obtain preset working display area parameters, wherein the working display area parameters include the display area of ​​the display panel.

[0112] Step S1022: Calculating the distance data of the shift structure moving along the depth direction of the accommodating compartment according to the preset working display area parameters.

[0113] In some embodiments, step S102: calculating the distance data of the shift structure moving along the depth direction of the accommodating compartment according to the mode information, includes:

[0114] Step S1023: If the mode information is characterized as automatic mode information, a vehicle speed parameter and a gear lever position parameter are acquired according to the vehicle speed sensor and the gear lever position sensor.

[0115] Step S1024: Calculate and obtain the distance data of the shift structure moving along the depth direction of the accommodating compartment according to the vehicle speed parameter and the gear lever position parameter.

[0116] Specifically, when the vehicle speed parameter is detected to be greater than 90 km / h, the display device assumes the first display mode. Due to the high speed of the vehicle at this time, the area of ​​the display panel exposed within the compartment is minimized, displaying only simple text information such as weather and time. This prevents distractions to the driver caused by a larger display panel area, thereby improving driving safety.

[0117] When the vehicle speed parameter is detected to be greater than 60 km / h and less than 90 km / h, the display device enters a second display mode, where the display panel displays a larger area than in the first display mode. Because the vehicle speed is moderate, some vehicle information, such as the remaining battery life of the electric vehicle, can be displayed. Graphical information, such as a music player, can also be displayed to help the driver relax.

[0118] When the vehicle speed parameter is detected to be greater than 0 km / h and less than 60 km / h, that is, when the vehicle speed is detected to be greater than 0 km / h and less than 60 km / h, the display device enters the third display mode, and the display panel's display area is larger than that in the second display mode. Because the vehicle speed is slower at this time, the driving factor is higher, and a larger navigation screen is provided to the user, which allows the driver to see the navigation screen clearly without causing any interference.

[0119] When it is detected that the gear lever is in the reverse gear position, that is, when it is detected that the vehicle is reversing, the display device presents a third display mode, and the display area of ​​the display panel is larger than the display area in the second display mode to provide the driver with a large-size reversing image.

[0120] When the gear lever is detected to be in the parking position or the vehicle speed parameter is detected to be 0 km / h, that is, when the vehicle is detected to be in a parked state, the display device can present a fourth display mode, and the display panel is completely extended out of the storage compartment. At this time, the display panel is displayed in full screen, and the user can perform entertainment activities on the display panel.

[0121] When the gear lever is in the parking position or the vehicle speed parameter is detected to be 0 km / h, that is, when the vehicle is detected to be in a parked state, the display panel is completely retracted into the storage compartment. At this time, when the user is not in the vehicle, the display panel is completely retracted into the storage compartment to prevent sun aging.

[0122] It should be readily understood that “on,” “above,” and “over” in this application should be interpreted in the broadest manner, such that “on” means not only “directly on something,” but also includes “on something” with intervening features or layers therebetween, and “above” or “over” includes not only the meaning of “above” or “over,” but also includes the meaning of “above” or “over” with no intervening features or layers therebetween (i.e., directly on something).

[0123] As used herein, the term "substrate substrate" refers to the material on which subsequent material layers are added. The substrate substrate itself can be patterned. The material added on top of the substrate substrate can be patterned, or it can remain unpatterned. In addition, the substrate substrate can include a wide range of materials, such as silicon, germanium, gallium arsenide, indium phosphide, etc. Alternatively, the substrate substrate can be made of a non-conductive material (e.g., glass, plastic, or sapphire wafer, etc.).

[0124] As used herein, the term "layer" may refer to a portion of a material comprising an area having a certain thickness. A layer may extend over the entire underlying structure or overlying structure, or may have an extent smaller than the extent of the underlying or overlying structure. In addition, a layer may be an area of ​​a homogeneous or inhomogeneous continuous structure whose thickness is less than the thickness of the continuous structure. For example, a layer may be located between the top and bottom surfaces of a continuous structure or between any pairs of lateral planes at the top and bottom surfaces. A layer may extend laterally, vertically, and / or along a tapered surface. A substrate may be a layer, may include one or more layers therein, and / or may have one or more layers located thereon, above, and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductors and a contact layer (within which contacts, interconnects, and / or vias are formed) and one or more dielectric layers.
