[0076] Detailed description

[0077] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0078] In the related art, the display screen of an L-shaped vehicle-mounted display device usually has two states: an ascending state and a descending state. The ascending state refers to the state in which the display screen is fully exposed, and the descending state refers to the state in which the display screen is partially exposed. The switching between these two states is generally achieved through a driving unit in the vehicle-mounted display device. The driving unit can drive one side of the display screen to move, and use a tensioning structure to keep the display screen always tensioned, thereby achieving the switching of the display screen state.

[0079] When the driving unit drives one side of the display screen to move away from the location of the driving unit, the other side of the display screen will drive the display screen to switch its state under the action of the tensioning structure. However, at this time, since the side of the display screen that is under force (that is, the side where the driving unit is located) will be subjected to an additional force from the driving unit, the display screen will be arched at the position of the rolling axis, that is, the display screen is not in contact with the supporting part behind it, which affects the use of the vehicle-mounted display device.

[0080] In view of this, an embodiment of the present application proposes a vehicle-mounted display device, which is provided with a flexible display part, a first moving part and a second moving part, and a tensioning structure is provided between the first moving part and the second moving part, wherein the first moving part and the second moving part are respectively connected to the two sides of the flexible display part, and the first moving part and the second moving part can move relative to each other; then a driving device is used to drive the first moving part to move before the second moving part, so that the first moving part drives the second moving part to move through the flexible display part; or, the driving device is used to drive the second moving part to move before the first moving part through the tensioning structure, and then the second moving part drives the first moving part to move through the flexible display part; in this way, the flexible display part can always maintain pressure on the axis when switching, thereby reducing the phenomenon of the flexible display part arching at the position of the axis, thereby improving the user experience.

[0081] Referring to Figures 1, 2 and 3, an embodiment of the present application discloses a vehicle-mounted display device, which includes a flexible display portion 10, a supporting unit 50 for supporting the flexible display portion 10, a driving device 40 (not shown in the figures) for driving the flexible display portion 10 to change its state, and a accommodating structure 20.

[0082] Specifically, the housing structure 20 is mainly used to accommodate the structures related to the vehicle-mounted display device, and to protect and hide these structures. For example, the support unit 50 and the drive device 40 can both be located inside the housing structure 20, but at least part of the flexible display portion 10 is located outside the housing structure 20 for displaying images. In the embodiment of the present application, the housing structure 20 may include a box body 201, a front frame 202, a side frame 203, and a rear frame 204. The support unit 50 and the drive device 40 of the vehicle-mounted display device can both be placed inside the box body 201; the front frame 202 can cover the frame of the flexible display portion 10 to provide protection; the side frame 203 and the rear frame 204 mainly serve to cover the entire vehicle-mounted display device to provide protection; of course, the housing structure 20 can also be part of the dashboard on the vehicle.

[0083] The flexible display portion 10 is a flexible display module with a display function. For example, the flexible display portion 10 can be an OLED (Organic Light-Emitting Diode) display module. Referring to Figures 1 and 2, the flexible display portion 10 has two states: an ascending state and a descending state. When the flexible display portion 10 is in the descending state, only a portion of the flexible display portion 10 (for example, a flexible display portion 10 of one-third of the area) is located outside the accommodating structure 20 for image display; when the flexible display portion 10 is in the ascending state, all of the flexible display portion 10 is located outside the accommodating structure 20 for image display. That is to say, the flexible display portion 10 in the ascending state has a larger display area than the flexible display portion 10 in the descending state. Of course, the flexible display portion 10 in the ascending state can also display more image content than the flexible display portion 10 in the descending state.

[0084] 3, 4 and 5, the support unit 50 includes a mounting portion, a first moving portion 11 and a second moving portion 12. The mounting portion includes a first fixing portion 13 and a second fixing portion 14, which are connected to each other, and the plane where the first fixing portion 13 is located intersects with the plane where the second fixing portion 14 is located. In other words, the first fixing portion 13 and the second fixing portion 14 form a certain angle, which can be 60°, 75°, 90°, 105°, 120°, and so on. In the embodiment of the present application, the first fixing portion 13 and the second fixing portion 14 are perpendicular to each other.

[0085] At the same time, the first moving portion 11 is slidably connected to the first fixed portion 13 along a first direction X, and the second moving portion 12 is slidably connected to the second fixed portion 14 along a second direction Y. The first direction X and the second direction Y are perpendicular to each other. In other words, the plane on which the first moving portion 11 lies is also perpendicular to the plane on which the second moving portion 12 lies. Of course, when the first fixed portion 13 and the second fixed portion 14 are in a non-perpendicular state, the first moving portion 11 and the second moving portion 12 are also in a non-perpendicular state. In addition, in the embodiment of the present application, in order to facilitate the movement of the first moving part 11, the first fixed part 13 is set to a hollow frame structure, and the first moving part 11 is slidably connected to the first fixed part 13 at the frame position of the first fixed part 13, so that the first moving part 11 can avoid large-area contact between the first fixed part 13, which is more conducive to the movement of the first moving part 11; the second fixed part 14 is set to a plate structure, and the flexible display part 10 is fitted with the plate surface of the second fixed part 14, so that the flexible display part 10 can be made flatter (and the back support of the flexible display part 10 is improved), thereby ensuring the display effect of the flexible display part 10.

[0086] The two sides of the flexible display portion 10 are respectively connected to the first moving portion 11 and the second moving portion 12, and the flexible display portion 10 is kept in contact with the second fixed portion 14. It is understandable that the first moving portion 11 and the second moving portion 12 can move relative to each other. For example, when the flexible display portion 10 is converted from a descending state to an ascending state, the first moving portion 11 will move toward the position where the second fixed portion 14 is located, and the second moving portion 12 will move toward a position away from the second fixed portion 14, thereby exposing and displaying the flexible display portion 10 hidden in the accommodating structure 20; when the flexible display portion 10 is converted from an ascending state to a descending state, the first moving portion 11 will move toward a position away from the second fixed portion 14, and the second moving portion 12 will move toward a position close to the second fixed portion 14, thereby hiding part of the flexible display portion 10 in the accommodating structure 20 again.

[0087] In addition, as shown in Figure 4, a plurality of slots are provided on the second fixing portion 14 on a side away from the second moving portion 12, and support shafts 15 are rotatably connected in these slots. The flexible display portion 10 also maintains contact with these support shafts 15 to facilitate better movement of the flexible display portion 10.

[0088] A tensioning structure 30 is also provided between the first moving portion 11 and the second moving portion 12. Since force is typically applied to only one side of the flexible display portion 10 when switching between different states, the tensioning structure 30 is required to enable relative movement of the first moving portion 11 and the second moving portion 12 to ensure normal movement of the entire flexible display portion 10. For example, when force is applied to the first moving portion 11, it drives one side of the flexible display portion 10 to move. Simultaneously, the first moving portion 11, through the tensioning structure 30, causes the second moving portion 12 to move relative to it, thereby causing the other side of the flexible display portion 10 to move relative to it.

[0089] The driving device 40 is a power source for driving the flexible display portion 10 to change its state. That is, the driving device 40 can generate a force on the first moving portion 11 or the second moving portion 12, thereby realizing the movement of the flexible display portion 10. For example, when the driving device 40 is connected to the first moving portion 11, the driving device 40 can drive the first moving portion 11 to move in a direction away from the second fixed portion 14, thereby causing the flexible display portion 10 to transition from an ascending state to a descending state; however, when the driving device 40 drives the first moving portion 11 to move in a direction close to the second fixed portion 14, that is, when the flexible display portion 10 transitions from a descending state to an ascending state, the movement of the flexible display portion 10 is mainly achieved by the tensioning structure 30. However, since the flexible display portion 10 is subjected to an additional force from the driving device 40, the flexible display portion 10 may be arched at the position of the support shaft 15.

[0090] In order to reduce the arching phenomenon of the flexible display portion 10 , in the embodiment of the present application, the driving device 40 includes a first driving state and a second driving state.

[0091] Specifically, in the first driving state, the driving device 40 drives the first moving part 11 to move before the second moving part 12. That is, the first moving part 11 directly generates a force on the flexible display part 10, and then the flexible display part 10 drives the movement of the second moving part 12. At this time, the tensioning structure 30 will of course also have a certain tensioning effect, but the flexible display part 10 will always be subjected to the pulling force of the first moving part 11, thereby allowing the flexible display part 10 to always generate pressure on the support shaft 15, thereby reducing the arching phenomenon of the flexible display part 10. In the embodiment of the present application, in the first driving state, the flexible display part 10 is converted from an ascending state to a descending state.

[0092] In the second driving state, the driving device 40 drives the second moving part 12 to move before the first moving part 11 through the tensioning structure 30. That is, the driving device 40 will first apply force to the second moving part 12 through the tensioning structure 30, and then the second moving part 12 will generate force on the flexible display part 10, and then the flexible display part 10 will drive the movement of the first moving part 11. In this process, since the second moving part 12 moves first, the flexible display part 10 will always be subjected to the pulling force of the second moving part 12, thereby allowing the flexible display part 10 to always generate pressure on the support shaft 15, reducing the arching phenomenon of the flexible display part 10. In the embodiment of the present application, in the second driving state, the flexible display part 10 is converted from a descending state to an ascending state.

[0093] In this way, the flexible display portion 10 can always exert pressure on the support shaft 15 regardless of whether it is converted from the ascending state to the descending state or from the descending state to the ascending state, thereby reducing the arching phenomenon of the flexible display portion 10 .

[0094] Specifically, as shown in FIG6 , the drive device 40 includes a drive unit 41 and a slider 42 mounted on the drive unit 41 . The slider 42 is provided with a drive reversing block 43 . The drive unit 41 can drive the slider 42 and the drive reversing block 43 to move along the first direction X. The drive device 40 also includes a first drive portion 44 and a second drive portion 45 connected to each other. The first drive portion 44 is connected to the first moving portion 11 , and the second drive portion 45 is connected to the tensioning structure 30 . The first drive portion 44 and the second drive portion 45 can be used to achieve different driving states of the drive device 40 .

[0095] As shown in Figure 7, in the first driving state, the driving unit 41 drives the slider 42 to drive the driving reversing block 43 to contact the first driving part 44 and disengage from the second driving part 45. At this time, the force generated by the driving unit 41 is transmitted to the first moving part 11 through the driving reversing block 43 and the first driving part 44, but cannot be transmitted to the tensioning structure 30 through the second driving part 45. Therefore, the first moving part 11 will move before the second moving part 12.

[0096] As shown in Figure 7, in the second driving state, the driving unit 41 drives the slider 42 to drive the driving reversing block 43 to contact the second driving part 45 and disengage from the first driving part 44. At this time, the force generated by the driving unit 41 is transmitted to the tensioning structure 30 through the driving reversing block 43 and the second driving part 45, but cannot be transmitted to the first moving part 11 through the first driving part 44. Therefore, the tensioning structure 30 will first transmit the force to the second moving part 12, so that the second moving part 12 can move before the first moving part 11.

[0097] In the embodiment of the present application, as shown in Figures 8 and 9, the driving commutation block 43 includes a first contact portion 431 and a second contact portion 432. The first contact portion 431 and the second contact portion 432 are both hook structures extending from the driving commutation block 43. It can be understood that the first contact portion 431 extends toward the first driving portion 44, and the second contact portion 432 extends toward the second driving portion 45. At the same time, a first groove 441 is formed on the first driving portion 44, and a second groove 451 is formed on the second driving portion 45. The first contact portion 431 is located in the first groove 441, and the second contact portion 432 is located in the second groove 451.

[0098] As shown in Figure 8, in the first driving state, the driving unit 41 generates a force on the slider 42, so that the slider 42 drives the first contact portion 431 of the driving reversing block 43 to contact the inner wall of the first groove 441, and the second contact portion 432 is disengaged from the inner wall of the second groove 451. That is to say, at this time, the driving reversing block 43 has a connection relationship with the first driving portion 44 and has no connection relationship with the second driving portion 45, so that the driving reversing block 43 can transmit force to the first driving portion 44 and the first moving portion 11.

[0099] As shown in Figure 9, in the second driving state, the driving unit 41 generates a force on the slider 42, so that the slider 42 drives the second contact portion 432 of the driving reversing block 43 to contact the inner wall of the second groove 451, and the first contact portion 431 is disengaged from the inner wall of the first groove 441. That is to say, at this time, the driving reversing block 43 is connected to the second driving portion 45 and has no connection with the first driving portion 44, so that the driving reversing block 43 can transmit force to the second driving portion 45 and the tensioning structure 30.

[0100] It should be noted that the first contact portion 431 contacts the inner wall of the first groove 441, which can also be understood as the hook of the first contact portion 431 hooking the first driving portion 44, thereby realizing force transmission; similarly, the second contact portion 432 contacts the inner wall of the second groove 451, which can also be understood as the hook of the second contact portion 432 hooking the second driving portion 45, thereby realizing force transmission.

[0101] Therefore, by driving the reversing block 43, the first driving part 44 and the second driving part 45, the driving device 40 can drive the first moving part 11 or the second moving part 12 to move before the other in the first driving state and the second driving state respectively, so that the flexible display part 10 can always generate pressure on the support shaft 15, thereby reducing the arching phenomenon of the flexible display part 10 and improving the user experience.

[0102] In one embodiment, as shown in FIG6 , the drive unit 41 may include a fixed slot 411 and a motor 412 disposed at one end of the fixed slot 411. The fixed slot 411 may be fixed within the housing structure 20 and extend along a first direction X. A lead screw 413 is fixedly connected to the output end of the motor 412. The lead screw 413 is located within the fixed slot 411 and extends along the length of the fixed slot 411. Simultaneously, a slider 42 is slidably connected within the fixed slot 411 and is threadedly connected to the lead screw 413.

[0103] In this way, when the motor 412 drives the screw 413 to rotate, since the slider 42 is located in the fixed slide groove 411, the slider 42 cannot rotate with the screw 413. At the same time, the slider 42 is threadedly connected to the screw 413, so the slider 42 will move on the screw 413 along the length direction of the screw 413, and then the slider 42 can drive the reversing block 43 to move.

[0104] In one embodiment, as shown in FIG5 , the first moving portion 11 is a plate structure, and guide rails 131 are provided on both sides of the first moving portion 11 on the first fixed portion 13. The guide rails 131 extend along the first direction X, and the two sides of the first moving portion 11 are slidably connected to the two guide rails 131. In this way, the first moving portion 11 can slide on the first fixed portion 13.

[0105] In one embodiment, as shown in FIG4 , the second fixed portion 14 and the second movable portion 12 are both in the shape of comb teeth. Specifically, the second fixed portion 14 includes a plurality of first comb teeth 141, and a first receiving groove 142 is formed between two adjacent first comb teeth 141. It can be understood that the first comb teeth 141 extend along the second direction Y; at the same time, the second movable portion 12 includes a plurality of second comb teeth 121, and a second receiving groove 122 is formed between two adjacent second comb teeth 121; wherein the first comb teeth 141 are slidably connected to the second receiving groove 122, and the second comb teeth 121 are slidably connected to the first receiving groove 142. In this way, the sliding of the second movable portion 12 on the second fixed portion 14 can be achieved, and the flexible display portion 10 has a support structure behind it regardless of whether it is in an ascending state or a descending state, thereby ensuring the display effect of the flexible display portion 10.

[0106] It should be noted that the second moving portion 12 has two more second comb teeth 121 than the second fixed portion 14, and these two second comb teeth 121 are located on either side of the second fixed portion 14. Furthermore, the second receiving slot 122 may not completely penetrate the second moving portion 12, but the first receiving slot 142 needs to completely penetrate the second fixed portion 14.

[0107] In addition, as shown in FIG4 , in one embodiment, a plurality of mounting grooves 1411 may be provided on the first comb teeth 141, and a magnetic member (not shown) may be provided in each mounting groove 1411. These magnetic members may generate an attractive force on the flexible display portion 10, thereby maintaining contact between the flexible display portion 10 and the second fixing portion 14, further reducing the bulging of the flexible display portion 10.

[0108] In the embodiment of the present application, the mounting groove 1411 is configured to be in a strip shape, and the mounting groove 1411 extends along the second direction Y. In other embodiments, the mounting groove 1411 may also be configured to be circular, square, polygonal, etc.

[0109] In the related art, the tensioning system used in the L-shaped vehicle-mounted display device has a poor service life, which affects the service life of the vehicle-mounted display device.

[0110] In order to increase the service life of the vehicle-mounted display device, an embodiment of the present application further provides a vehicle-mounted display device, in which the tensioning structure 30 includes at least two groups of tensioning members.

[0111] Specifically, as shown in FIG. 5 , the tensioning structure 30 includes two groups of tensioning members, and the two groups of tensioning members are symmetrically distributed.

[0112] As shown in Figures 10 and 11, the tensioning member includes a first reversing roller 31, a second reversing roller 32, a third reversing roller 33, and a tensioning belt 34. The first reversing roller 31 is rotatably connected to the first fixed portion 13, the second reversing roller 32 is rotatably connected to the second fixed portion 14, and the third reversing roller 33 is rotatably connected to the support shaft 15. One end of the tensioning belt 34 is fixedly connected to the first moving portion 11. The tensioning belt 34 then passes through the first reversing roller 31, the third reversing roller 33, and the second reversing roller 32 in sequence before being fixedly connected to the second moving portion 12. (The first moving portion 11 and the second moving portion 12 are not shown in Figures 10 and 11.)

[0113] It should be noted that, because the drive device 40 needs to drive the first moving part 11 or the second moving part 12 to move first under different driving conditions, the end of the tension belt 34 originally connected to the first moving part 11 is not directly connected to the first moving part 11. Referring to the embodiment of the present application, as shown in FIG5 , the end of the tension belt 34 is fixedly connected to the first driving part 44, and the tension belt 34 is also fixedly connected to the second driving part 45. In this way, the drive unit 41 can use the first driving part 44 to drive the first moving part 11 to move and enable the tensioning structure 30 to function; the drive unit 41 can also use the second driving part 45 to drive the second moving part 12 to move through the tensioning structure 30. It can also be understood that the tension belt 34 is connected to the second driving part 45, and the first driving part 44 and the second driving part 45 are also connected via the tension belt 34.

[0114] Meanwhile, in the embodiment of the present application, the tensioning band 34 is made of polyimide. The tensioning band 34 made of polyimide can increase the service life of the tensioning structure 30, thereby increasing the service life of the vehicle-mounted display device.

[0115] As shown in Figure 12, bearing mounting blocks 311 are provided on either side of the first reversing roller 31 on the first fixing portion 13. First bearings 312 are fixedly connected to the bearing mounting blocks 311. The first reversing roller 31 is rotatably connected to the bearing mounting blocks 311 via the first bearings 312. Another set of first reversing rollers 31 is provided between the bearing mounting blocks 311 on either side, and a tension belt 34 is sequentially wound around the two first reversing rollers 31. The two first reversing rollers 31 ensure that the tension belt 34 extends along the first direction X, reducing the risk of the tension belt 34 tilting.

[0116] As shown in Figure 13, the second reversing roller 32 is located between two adjacent first comb teeth 141. An opening that penetrates the second moving portion 12 is formed on the second reversing roller 32. A groove is formed on the first comb teeth 141, and the end of the second reversing roller 32 is located in the groove. A pressure block 1413 is also provided on the first comb teeth 141 at the position of the groove. The pressure block is fixedly connected to the second comb teeth 121 via screws, and the pressure block confines the end of the second reversing roller 32 in the groove.

[0117] As shown in Figure 14, the third reversing roller 33 is rotatably set on the support shaft 15, but since the flexible display part 10 also needs to contact the support shaft 15, in order to avoid interference, in an embodiment of the present application, a sleeve shaft 151 is provided on the support shaft 15, and the sleeve shaft 151 is fixedly connected to the support shaft 15, and the diameter of the sleeve shaft 151 is larger than the diameter of the third reversing roller 33. Then, the flexible display part 10 is in contact with the sleeve shaft 151, which can avoid interference between the flexible display part 10 and the tensioning belt 34.

[0118] Second bearings 331 are provided at both ends of the third reversing roller 33. The second bearings 331 are sleeved on the support shaft 15. The third reversing roller 33 is rotatably connected to the support shaft 15 via the second bearings 331, and the rotation of the third reversing roller 33 does not affect the rotation of the support shaft 15. Furthermore, limit springs 332 are provided at both ends of the third reversing roller 33 on the support shaft 15 to limit the axial movement of the third reversing roller 33 on the support shaft 15.

[0119] 17 , the tensioning member further includes a fixing member 36 , which is disposed at the end of the tensioning belt 34 . The fixing member 36 is used to connect the end of the tensioning belt 34 to the first moving part 11 or the second moving part 12 .

[0120] Specifically, the fixing member 36 may include a fixed pressure plate 361 having an opening therein. When the tensioning belt 34 is fixed, the tensioning belt 34 is positioned between the fixed pressure plate 361 and the position to be fixed. For example, in the embodiment of the present application, the tensioning belt 34 is connected to the first drive unit 44, and thus positioned between the fixed pressure plate 361 and the first drive unit 44. The fixed pressure plate 361 and the first tensioning belt 34 are connected by screws, thereby securing the tensioning belt 34. The screws may or may not pass through the tensioning belt 34. Furthermore, a fixing slot 362 may be provided at the position to be fixed, such as the first drive unit 44. The size of the fixing slot 362 matches the size of the fixing pressure plate 361, and the fixing pressure plate 361 is positioned within the fixing slot 362. The fixing slot 362 can better restrict the position of the fixing pressure plate 361.

[0121] 15 and 16 , the tensioning member may further include a movable roller 35 . The movable roller 35 is disposed on the first moving portion 11 , and the tensioning belt 34 is wound around the movable roller 35 .

[0122] It can be understood that in the embodiment of the present application, the movable roller 35 is arranged on the first driving part 44, and the tensioning belt 34 passes around the movable roller 35 and then passes around the first reversing roller 31. The movable roller 35 can be used to tension the flexible display part 10 in the descending state.

[0123] In one embodiment, the vehicle-mounted display device may further include a control unit, which is connected to the driving device 40. The control unit can control the driving device 40 to switch to a first driving state and a second driving state. For example, when the flexible display part 10 needs to be converted from a descending state to an ascending state, the driving device 40 is controlled to move the flexible display part 10 in the second driving state; when the flexible display part 10 needs to be converted from an ascending state to a descending state, the driving device 40 is controlled to move the flexible display part 10 in the first driving state.

[0124] In one embodiment, the vehicle-mounted display device may further include a display unit connected to the flexible display portion 10, and configured to control the flexible display portion 10 to emit light to display image content. The display unit may include a control circuit board and a control chip, etc.

[0125] The present application also provides a state switching method for the vehicle-mounted display device provided in any of the above embodiments, comprising:

[0126] Receive state switching command;

[0127] In response to the state switching command indicating that the state of the flexible display portion is switched from the ascending state to the descending state, the driving device drives the first moving portion to move before the second moving portion, so that the first moving portion drives the second moving portion to move through the flexible display portion;

[0128] In response to the state switching command indicating that the state of the flexible display portion is converted from a descending state to an ascending state, the second moving portion is driven to move before the first moving portion through the tensioning structure, so that the second moving portion drives the first moving portion to move through the flexible display portion.
