Description

Technical Field

[0001] The utility model relates to the field of display technology, and in particular to a display device and a vehicle. Background Art

[0002] With the advancement of technology, display screens are used more and more widely in areas such as transportation, and are carrying more and more functions. For example, multimedia, video calls, navigation displays, reversing images, and central control functions in cars all require display screens to achieve.

[0003] Taking the in-car scenario as an example, the central control screen is mostly a single screen that can only cope with a single scenario, such as navigation, vehicle information display, multimedia entertainment, and reversing images. When multiple functions are used overlappingly, a single screen cannot cope with it.

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In the embodiments of the present application, the expressions "A and / or B" all represent A, B, and A and B.

[0049] Combination Figure 1 and Figure 2 :

[0050] The display device provided in the embodiment of the present application includes: a display unit 10, a driving unit T and a control unit, wherein the control unit is used to control the driving unit T to drive the display unit 10 to switch between a splicing state and a separation state; the display unit 10 includes a first display screen 11 and a second display screen 12, Figure 1 When the display unit 10 is in a splicing state, the distance between the corresponding sides of the first display screen 11 and the second display screen 12 is less than or equal to 140 microns, for example, it can be 140 microns, 130 microns, 120 microns, 110 microns, 100 microns, 80 microns, 70 microns, 50 microns, 40 microns and 30 microns, etc. In a scenario where the splicing requirements are high, the human eye is not easy to detect the splicing seam, and the control unit controls the first display screen 11 and the second display screen 12 to display the picture in coordination. The "coordinated display picture" means that the first display screen 11 and the second display screen 12 are displayed synchronously and spliced ​​to form the same picture. For example, the first display screen 11 displays the left half of the picture, and the second display screen 12 displays the right half of the picture, which is equivalent to the first display screen 11 and the second display screen 12 being spliced ​​into an overall display area to achieve a larger display, so that users can enjoy a large-screen experience. For reference Figure 2 When the display unit 10 is in a separated state, the distance between the corresponding sides of the first display screen 11 and the second display screen 12 is greater than or equal to 1 cm, for example, it can be 1 cm, 2 cm, 5 cm, 10 cm, 15 cm and 20 cm, etc. At this time, the first display screen 11 control unit controls the first display screen 11 and the second display screen 12 to display pictures independently. "Displaying pictures independently" can be displaying the same picture respectively, but the pictures displayed by both are complete and independent, or different pictures, and there is no correlation between the two pictures. Therefore, the first display screen 11 and the second display screen 12 are located at different positions, respectively, with different and relatively better distances and viewing angles to provide users with a good viewing experience.

[0051] It should be noted that the above-mentioned "user" may refer to a user at the same position. For example, the "user" targeted by the office computer using the above-mentioned display device may be a user at the same position, while in the separated state of the vehicle-mounted scene, the "user" targeted may be a user at two different positions, namely the main driver's seat and the co-driver's seat. In addition, the display device can also be used as a teaching blackboard. When a larger picture needs to be displayed, the first display screen 11 and the second display screen 12 are in a spliced ​​state and can be located in the middle of the front wall of the classroom. When a smaller picture needs to be displayed, the first display screen 11 and the second display screen 12 can be moved to the left and right sides respectively, so that students on both sides can see the contents on the blackboard from a better perspective.

[0052] As described above, the display device can cope with different scenarios in a more flexible manner.

[0053] In a specific embodiment, reference Figure 3 The driving unit T includes a preliminary adjustment mechanism T1 and a seam adjustment mechanism T2; when the display unit 10 is switched to the splicing state, the control unit is used to control the preliminary adjustment mechanism T1 to drive the first display screen 11 and the second display screen 12 to approach each other, so that the first display screen 11 and the second display screen 12 are initially close to each other, but do not directly collide with each other. The reason is that the control accuracy of the preliminary adjustment mechanism T1 is difficult to make the first display screen 11 and the second display screen 12 seamlessly spliced. At the same time, the impact force will not cause the first display screen 11 and the second display screen 12 to cause dead lights, bad lines, broken screens, etc. due to collision. The seam adjustment mechanism T2 is used to reduce the seam between the first display screen 11 and the second display screen 12 to a first distance W1, and the first distance W1 is less than or equal to 140 microns. It can be further used The user cannot visually perceive the existence of the splicing seam. In the above, the preliminary adjustment mechanism T1 is first used to greatly adjust the first display screen 11 and the second display screen 12 to complete the preliminary adjustment, and then the splicing seam adjustment mechanism T2 is used to slightly adjust the distance between the two, so that it can be quickly switched between the splicing state and the separation state, and seamless splicing can be achieved while protecting the first display screen 11 and the second display screen 12 from being broken; when the display unit 10 is switched to the separation state, the control unit is used to control the preliminary adjustment mechanism T1 to drive the first display screen 11 and the second display screen 12 to move away from each other, and the splicing seam adjustment mechanism T2 is reset until the distance between the first display screen 11 and the second display screen 12 is expanded to the second distance W2, and the second distance W2 is greater than or equal to 1 cm, so that the switching to the separation state is quickly achieved.

[0054] The seam adjustment mechanism T2 may be in various forms. In a specific embodiment, the seam adjustment mechanism T2 includes an elastic reset member 104, which is used to provide an elastic reset force for the second display screen 12 to the direction of the first display screen 11. When the preliminary adjustment mechanism T1 makes the first display screen 11 and the second display screen 12 initially approach each other, the elastic reset member 104 provides an elastic reset force for the second display screen 12 to the direction of the first display screen 11, so that the second display screen 12 maintains a trend of automatically approaching the first display screen 11 under the action of the elastic reset force until the seam is reduced to the first distance W1, thereby achieving a visual effect of "no seam", and the first display screen 11 and the second display screen 12 are close to each other in a relatively elastic and "gentle" manner, and are not easily broken.

[0055] In a specific embodiment, reference Figure 4 , the elastic reset member 104 is a coil spring, the joint adjustment mechanism T2 also includes a limit assembly S and a connector 107, one end of the connector 107 is fixedly connected to the preliminary adjustment mechanism T1, and the other end is fixedly connected to a spring stopper 103, the limit assembly S is fixedly connected to the second display screen 12, the coil spring is sleeved on the connector 107, and elastically abuts between the limit assembly S and the spring stopper 103, wherein the connector 107 plays a guiding and limiting role on the coil spring. Reference Figure 5 When the preliminary adjustment mechanism T1 is first used to bring the first display screen 11 and the second display screen 12 closer to each other, after the preliminary adjustment is completed, the coil spring is compressed by the limit component S and the spring stop head 103, and drives the limit component S to move away from the spring stop head 103, so that the second display screen 12 is brought closer to the first display screen 11, so as to achieve a "seamless" visual effect.

[0056] By controlling the length and wire diameter of the coil spring, the force of resetting the module can be controlled below 5N, effectively reducing the damage to the first display screen 11 and the second display screen 12 caused by collision.

[0057] In a specific embodiment, reference Figure 4 The limit assembly S includes a spring fixing block 105 and a baffle 102, the spring fixing block 105 is fixedly connected to the second display screen 12, the spring fixing block 105 has a mounting groove 106, the connector 107 is at least partially located in the mounting groove 106, and the reference Figure 5 When the display unit 10 is in the separated state, the spring stopper 103 abuts against the bottom of the mounting groove 106 to push the bottom of the mounting groove 106, so that the connector 107 can push the spring fixing block 105 through the spring stopper 103, so that the second display screen 12 is pushed away from the first display screen 11. Figure 6When the display unit 10 is in the splicing state, there is a set gap G between the spring stopper 103 and the bottom of the installation groove 106, so as to reserve redundant space for the connector 107 in the installation groove 106; the baffle 102 is located at the opening side of the installation groove 106 of the spring fixing block 105, and is detachably connected to the spring fixing block 105, and the coil spring elastically abuts between the baffle 102 and the spring stopper 103, so that the baffle 102 can be firstly sleeved on the connector 107, and the coil spring can be assembled on the connector 107 by using the spring stopper 103, and then the end of the connector 107 with the spring stopper 103 is placed in the installation groove 106, and then the baffle 102 can be detachably fixed to the opening side of the installation groove 106 of the spring fixing block 105 by using the bolt 101. The baffle 102 can prevent the spring stopper 103 and the coil spring from falling off. At the same time, the installation groove 106 has a protective effect on the coil spring.

[0058] In a specific embodiment, the size of the gap G is set between 2 mm and 5 mm, for example, it can be 2 mm, 3 mm, 4 mm and 5 mm, etc. If the size is too large, the spring stop head 103 will abut against the bottom of the installation groove 106, and it will not be easy to contact and push the spring fixing block 105. If the size is too small, the spring stop head 103 will easily contact the bottom of the installation groove 106, the stroke of the coil spring will be too small, and the joint adjustment ability will be limited.

[0059] The seam adjustment mechanism T2 is not limited to the above-mentioned form, and can also be replaced by a motor capable of accurately controlling the stroke combined with a transmission mechanism such as a gear rack. The motor capable of accurately controlling the stroke can be a stepper motor, a DC motor or a servo motor.

[0060] In a specific embodiment, the display device also includes a sensing unit P component and a human-computer interaction interface. The human-computer interaction interface can be a touch screen of the first display screen 11 and the second display screen 12, or a control button, etc. The sensing unit P can include a first sensor P1 set on the first display screen 11 and a second sensor P2 set on the second display screen 12. The first sensor P1 and the second sensor P2 are relatively arranged and can both be distance sensors. The splicing state or separation state of the first display screen 11 and the second display screen 12 is judged by the distance between the two. The control unit is used to: when the actual state of the display unit 10 obtained by the sensing unit P is consistent with the required state of the display unit 10 input by the human-computer interaction interface, control the first display screen 11 and the second display screen 12 to display the corresponding screen in the above actual state; when the actual state of the display unit 10 obtained by the sensing unit P is inconsistent with the required state of the display unit 10 input by the human-computer interaction interface, control the driving unit T to drive the display unit 10 to switch to the required state, and control the first display screen 11 and the second display screen 12 to display the corresponding screen in the required state.

[0061] Also refer to Figure 7 and Figure 8 After the user selects the required state through the human-computer interaction interface, the host computer determines whether the currently selected required state is a separation state or a splicing state, and the first controller 202 (refer to the following description) accesses the sensor unit P, and performs the following operations according to the state fed back by the sensor unit P: If the first display screen 11 and the second display screen 12 are already in the required state, the first controller 202 notifies the host computer 201 (refer to the following description) to directly issue instructions to the second controller (refer to the following description) to control the first display screen 11 and the second display screen 12 to switch to the corresponding screen under the required state; otherwise, the first controller 202 issues an instruction to the drive unit T to switch the state of the display unit. After the drive unit T feedbacks that the execution of the instruction has been completed, it issues an instruction to the second controller to control the first display screen 11 and the second display screen 12 to switch to the corresponding screen under the required state. For example, the user selects the splicing state of the main dashboard plus navigation, and the host computer 201 notifies the first controller 202 to access the sensor unit P. If the sensor unit P feedbacks that it is already in the splicing state, it directly issues instructions to the second controller to control the first display screen 11 and the second display screen 12 to display the screen in the splicing state. If the sensor unit P feedbacks that a certain position is in a non-fitting state, the first controller 202 issues an instruction to switch to the splicing state to the drive unit T, and the drive unit T feedbacks the execution completion instruction after executing the instruction. After receiving all the execution completion instructions, the first controller 202 notifies the host computer 201 to issue a control instruction to the second controller to switch the display screen of the first display screen 11 and the second display screen 12. The application whose required state is the separation state is similar to the control logic of the required state of the splicing state. Both first determine which positions need to be separated through the sensor unit P, and then execute the separation instruction through the drive unit T. After all drive units T have been executed, the display screen is switched.

[0062] In a specific embodiment, reference Figure 7 and Figure 8The control unit includes a host computer 201, a first controller 202, and a second controller. The host computer 201 is used to: according to the actual state of the display unit 10 obtained by the sensor unit P and the required state of the display unit 10 input by the human-computer interaction interface, issue a control instruction to the first controller 202, so that the first controller 202 controls the driving unit T to drive the display unit 10 to switch between the splicing state and the separation state, and to issue a control instruction to the second controller, so that the second controller controls the first display screen 11 and the second display screen 12 to display the screen in the corresponding state. The host computer 201 coordinates and controls the downstream first controller 202 and the second controller to control the driving function of the driving unit T and the screen display of the display unit 10 respectively. The first controller 202 and the second controller are controllers specially programmed for the corresponding functions, and the master controller (Master Control Unit, MCU) can be used, without programming the host computer 201 for the corresponding functions.

[0063] In a specific embodiment, reference Fig. 9 The display device also includes a buffer component 70, which is used to provide buffering for the first display screen 11 and the second display screen 12 when the display unit 10 is switched from a spliced ​​state to a separated state. When the display unit 10 is switched to the spliced ​​state, the risk of scratching the first display screen 11 and the second display screen 12 can be reduced.

[0064] In a specific embodiment, reference Fig. 9 The buffer assembly 70 includes a first magnet 71 and a second magnet 72. The first magnet 71 is fixed to the first display screen 11, and the second magnet 72 is fixed to the second display screen 12. When the display unit 10 switches to the splicing state, the first display screen 11 and the second display screen 12 are close to each other, and the corresponding polarities of the first magnet 71 and the second magnet 72 repel each other, which can provide repulsive force to slow down the speed of splicing and resetting the display unit 10, thereby alleviating the bumping problem. With this buffering method, compared with the use of flexible buffer material filling, there is no need to increase the joints.

[0065] In a specific embodiment, reference Fig. 9 The first display screen 11 is provided with a first positioning structure 61 facing the second display screen 12, and the second display screen 12 is provided with a second positioning structure 62 facing the first display screen 11. When the display unit 10 is switched to the splicing state, the first positioning structure 61 and the second positioning structure 62 are matched and combined with each other to achieve positioning, so as to alleviate the Fig.10 The step difference problem between the first display screen 11 and the second display screen 12 in the thickness direction can also alleviate the misalignment problem in the height direction.

[0066] In a specific embodiment, the first positioning structure 61 includes a guide protrusion 611 whose cross-sectional area gradually decreases in the direction away from the first display screen 11, and the second positioning structure 62 includes a guide groove 621 that matches the guide protrusion. For example, the guide protrusion 611 is a wedge-shaped block, and the guide groove 621 is a wedge-shaped groove, or the guide protrusion 611 is a conical column (such as a conical column), and the guide groove 621 is a conical groove (such as a conical groove); or, the first positioning structure 61 and the second positioning structure 62 are both magnets, and the corresponding polarities attract each other.
