[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] In the prior art, vehicle-mounted display devices such as ceiling screens, movable central control screens, movable seat screens, etc. are usually equipped with flipping and sliding functions. For the sliding function, a motor and a cable slider structure are usually used to achieve sliding. For the flipping function, a connecting rod structure is added on the basis of the sliding structure, so that the display can be synchronously flipped by the connecting rod during the sliding process. However, during the sliding process of the display, the torque of the connecting rod changes continuously, and the power output by the motor is difficult to adapt to the changing torque of the connecting rod, resulting in unstable current of the motor, thereby generating large noise. At the same time, controlling the flipping of the display by a connecting rod requires occupying a certain space along the thickness direction of the vehicle-mounted display device, thereby increasing the volume of the vehicle-mounted display device and reducing the usable rate of the space inside the vehicle.

[0039] The invention provides a vehicle-mounted display device.

[0040] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the vehicle-mounted display device includes:

[0041] Mounting member 100;

[0042] A display 200, which can move and rotate relative to the mounting member 100;

[0043] A mobile driving module 400, which is disposed on the mounting member 100 and is drivingly connected to the display 200 to drive the display 200 to move; and

[0044] The flip driving module 300 is connected to the mounting member 100 , and is used to drive the display 200 to rotate around the rotating shaft 210 .

[0045] The technical solution of the present invention is to separate the mobile driving module 400 for driving the display 200 to move and the flip driving module 300 for driving the display 200 to flip, and the mobile driving module 400 drives the display 200 to move on the mounting member 100, and the flip driving module 300 drives the display 200 to flip without interfering with each other. In combination with the linear movement of the display 200, the flip driving module 300 acts on the rotating shaft 210, so that the power of the flip driving module 300 to control the flipping of the display 200 and the power of the mobile driving module 400 to control the movement of the display 200 can be kept stable, thereby reducing the noise of the flip driving module 300 and the mobile driving module 400 during operation. At the same time, compared with the large space required to drive the display 200 to flip through a connecting rod, the flip driving module 300 and its driving process of flipping the display 200 occupy a smaller space in the thickness direction of the vehicle-mounted display device. In this way, the power driving the display 200 to flip and move can be kept stable, that is, the flip driving module 300 and the mobile driving module 400 can operate within a stable power, thereby reducing noise, reducing the excessive space in the vehicle, and improving the usable space in the vehicle.

[0046] It should be noted that the mobile drive module 400 and the flip drive module 300 can freely control the movement and flipping of the display 200, that is, the flipping and movement of the display 200 do not interfere with each other and can be controlled at any time. For example, the flip drive module 300 and the display 200 are synchronously controlled by the mobile drive module 400, and the flip drive module 300 always maintains a transmission connection with the display 200; or, the flip drive module 300 is fixed at a specific position of the mounting member 100, and when the mobile drive module 400 moves the display 200 to this position, the flip drive module 300 can be connected with the mobile drive module 400. The mobile driving module 400 is connected in transmission, such as the flip driving module 300 is provided with a gear at a specific position, the mobile driving module 400 acts on the rotating shaft 210 of the display 200, when the mobile driving module 400 drives the display 200 to move until the gear of its rotating shaft 210 is engaged with the gear of the flip driving module 300, the mobile driving module 400 stops running, the flip driving module 300 can drive the display 200 to flip, and the mobile driving module 400 can push the bearing sleeved on the rotating shaft 210 to move, so as to avoid interfering with the flipping of the display 200 under the control of the flip driving module 300.

[0047] As for the way in which the mobile drive module 400 controls the movement of the display 200, it can act on the rotating shaft 210 of the display 200 or directly act on the body of the display 200 through a pair of screw rods 410, gear racks, belts, etc., and as for the way in which the flip drive module 300 controls the flipping of the display 200, it can act on the rotating shaft 210 through gears or be transmitted to the rotating shaft 210 through a chain. In addition, the flip drive module 300 can be connected to the mounting member 100 directly or indirectly, such as being set on the mobile drive module 400 and indirectly connected to the mounting member 100 through the mobile drive module 400. Without loss of generality, the vehicle-mounted display device can be installed at different positions in the vehicle. For example, if the vehicle-mounted display device is installed on the roof, the display 200 is configured as a ceiling screen, and the mounting component 100 includes a peripheral frame and an inner plate to mount the display 200 on the roof, presenting a horizontal placement posture; if the vehicle-mounted display device is installed in the central control position, the display 200 is configured as a central control screen, and the mounting component 100 is arranged on the dashboard, which can be fixed to the dashboard or independently arranged from the dashboard, presenting a vertical placement posture; if the vehicle-mounted display device is installed on the seat back, the display 200 is configured as a seat display screen, and the mounting component 100 is arranged on the seat back, which can be fixed to the seat back or independently arranged from the seat back, presenting a vertical placement posture.

[0048] In this embodiment, please refer to Figure 1 and Figure 5 , the display 200 is configured as a ceiling screen. It can be understood that the ceiling screen has a flipping and moving activity form, which can meet the entertainment needs of the rear passengers. At the same time, the posture of the ceiling screen can be adjusted to a state facing the rear when it is needed, and adjusted to a state close to the roof when it is not needed, thereby reducing the occupied vehicle space and improving the utilization rate of the interior space. In particular, the following embodiments can also be described or understood with reference to the state of the ceiling screen.

[0049] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, the flip drive module 300 is arranged on the mobile drive module 400, and the mobile drive module 400 is connected to the display 200 through the flip drive module 300 to drive the flip drive module 300 and the display 200 to move synchronously. It can be understood that when the mobile drive module 400 is running, the display 200 and the flip drive module 300 move synchronously. When it is necessary to control the display 200 to rotate, the flip drive module 300 controls the display 200 to rotate, forming a completely independent control mode for the movement and flipping of the display 200, and the user can more flexibly adjust the position and angle of the display 200 to adapt to different usage scenarios and needs. In addition, it is ensured that the flip drive module 300 directly acts on the rotating shaft 210 of the display 200, so that the power output by the flip drive module 300 can remain stable. Correspondingly, the mobile drive module 400 always controls the flip drive module 300 and the display 200 to move, and the power output by the mobile drive module 400 also remains stable, thereby reducing the noise emitted by the flip drive module 300 and the mobile drive module 400. In addition, the mobile drive module 400 is also connected to the display 200 through the flip drive module 300. Compared with the case where the transmission connection between the mobile drive module 400 and the display 200 and the transmission connection between the flip drive module 300 and the display 200 are completely independent, this embodiment reduces the transmission structure of the mobile drive module 400 being independently connected to the display 200, thereby reducing the complexity of the system and the number of components required, and improving the overall structural compactness and stability. Of course, in other embodiments, the flip drive module 300 can also be set at a predetermined position. After the mobile drive module 400 drives the display 200 to move to the predetermined position, the flip drive module 300 can be connected to the rotating shaft 210 of the display 200, thereby controlling the display 200 to flip.

[0050] In one embodiment, please refer to Figure 2 and Figure 3The flip driving module 300 includes a flip motor 310 and a transmission member 320, wherein the flip motor 310 is driven and connected to the transmission member 320, and the transmission member 320 is connected to the rotating shaft 210. It can be understood that by adjusting the transmission ratio of the transmission member 320, the relationship between the output speed of the flip motor 310 and the speed of the rotating shaft 210 can be accurately controlled, so that the user can adjust the flip speed of the display 200 as needed, thereby obtaining a smoother or faster flipping action. If the display 200 is heavy or requires a larger flipping torque, a larger transmission ratio can be selected to amplify the output torque of the flip motor 310, so that a smaller flip motor 310 can be selected, thereby reducing the volume of the vehicle-mounted display device. At the same time, it also helps to prevent the display 200 from shaking or deflecting due to uneven force during the flipping process, thereby improving the stability and reliability of the flipping action. Of course, in other embodiments, the display 200 can also be flipped by a cylinder and an eccentric wheel, or the motor shaft of the flip motor 310 is coaxially connected to the rotating shaft 210.

[0051] Further, in this embodiment, please refer to Figure 2 and Figure 3 , the flip motor 310 and the display 200 are arranged on the same side of the transmission member 320, a fixed plate 321 is arranged on the side of the transmission member 320 away from the flip motor 310, and the mobile driving module 400 is drivingly connected to the fixed plate 321. It can be understood that the mobile driving module 400 drives the display 200 to move through the flip driving module 300, the fixed plate 321 on the side of the transmission member 320 is drivingly connected to the mobile driving module 400, and the flip motor 310 is arranged on the side of the transmission member 320 away from the fixed plate 321, that is, the side of the transmission member 320 facing the display 200, which can avoid the flip driving motor from interfering with the mobile driving module 400 driving the fixed plate 321 to move, thereby reducing the size of the vehicle-mounted display device in the moving direction of the display 200, reducing the additional space occupation, and making the layout of the vehicle-mounted display device more compact. At the same time, the transmission member 320 is connected to the mobile drive module 400 through the fixed plate 321, rather than being directly connected to the mobile drive module 400, and the fixed plate 321 is located on the side of the transmission member 320 away from the display 200, so that the position where the mobile drive module 400 is connected to the flip drive module 300 is located on the distribution surface of the flip drive module 300 and the display 200, thereby reducing the thickness of the vehicle-mounted display device and reducing the in-vehicle space occupied by the vehicle-mounted display device. Of course, in other embodiments, the flip motor 310 can also be set on the side of the transmission member 320 away from the display 200, or, in the thickness direction of the vehicle-mounted display device, the mobile drive module 400 is connected to the transmission member 320 or the flip motor 310.

[0052] In one embodiment, please refer to Figure 3The transmission member 320 includes two worms (not shown) and two bevel gears (not shown), the two worms and the two bevel gears are alternately meshed, the flip motor 310 is drivingly connected to the worm located upstream, the rotating shaft 210 is coaxially fixed with a transmission gear, the downstream bevel gear is the transmission gear, or the downstream bevel gear is drivingly connected to the transmission gear. It should be noted that the alternating meshing design of the worm and the bevel gear can produce a larger transmission ratio, thereby providing a stronger flipping driving force for the flipping of the display 200. At the same time, the meshing characteristics of the worm and the bevel gear have good self-locking properties. When the worm stops rotating and the bevel gear remains in place, a good self-locking performance is formed for the display 200, which helps to prevent the display 200 from accidentally flipping due to external force interference during the flipping process, thereby improving the safety and stability of the vehicle-mounted display device. In addition, the transmission cooperation of the two worms and the two bevel gears can adjust the extension direction of the motor shaft of the flip motor 310 and the extension direction of the output shaft 330 of the transmission member 320 to be parallel, so that the flip motor 310 and the display 200 can be on the same side or opposite sides of the transmission member 320, so as to adjust the layout of the vehicle-mounted display device and reduce its volume. Among them, the upstream and downstream in the downstream bevel gear and the upstream worm are based on the transmission direction from the motor shaft of the flip motor 310 to the output shaft 330 of the transmission member 320. The worm or bevel gear close to the motor shaft is in the upstream, and the worm or bevel gear close to the output shaft 330 is in the downstream. Of course, in other embodiments, the transmission member 320 can also adjust the transmission ratio by the cooperation between multiple double gears.

[0053] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 6The vehicle-mounted display device also includes a sliding ornament 500. The mounting member 100 is provided with an avoidance opening 110 extending along the moving direction of the display 200. The rotating shaft 210 is passed through the avoidance opening 110. The sliding ornament 500 is covered on the avoidance opening 110 and is slidably connected to the mounting member 100. The sliding ornament 500 is fixedly connected to the transmission member 320. It can be understood that the avoidance opening 110 is used to avoid the movement of the rotating shaft 210 to ensure that the mobile drive module 400 can smoothly drive the display 200 to move. Here, the sliding ornament 500 is slidably covered on the avoidance opening 110. It can be seen that the sliding ornament 500 has a makeshift opening 520 for the rotating shaft 210 to pass through. At the same time, the sliding ornament 500 also moves synchronously with the control of the mobile drive module 400. When the display 200 moves, the sliding ornament 500 can slidably cover the avoidance opening 110 on the mounting member 100, which is not only beautiful, but also can prevent dust, debris, etc. from entering the transmission system and affecting the normal operation of the mobile drive module 400 and the flip drive module 300. The sliding decorative piece 500 is provided with a connecting arm 510, and the connecting arm 510 is fixedly connected to the transmission member 320, so that the sliding decorative piece 500 is connected to the flip driving module 300, and the mobile driving module 400 is driven to connect to the flip driving module 300. In the process of the display 200 moving, the sliding decorative piece 500 and the rotating shaft 210 move synchronously to avoid interference between the two. In addition, the sliding decorative piece 500 is fixedly connected to the transmission member 320. Referring to the above description of the fixed plate 321, the fixed plate 321 and the sliding decorative piece 500 are arranged on opposite sides of the transmission member 320, and the sliding decorative piece 500 is slidably connected to the mounting member 100, and the fixed plate 321 is also connected to the mounting member 100 through the mobile driving module 400. Then, the force and torque received by the flip driving module 300 can be balanced, which helps to reduce the vibration and shaking during the flipping process and improve the stability and reliability of the flipping action. Of course, in other embodiments, the sliding ornament 500 may be merely sleeved on the outer periphery of the rotating shaft 210 and slidably connected to the mounting member 100 , or the sliding ornament 500 may be controlled by an independent motor with a power adapted to the moving speed of the rotating shaft 210 .

[0054] In one embodiment, please refer to Figure 2 and Figure 6The mobile driving module 400 includes a slider 420, a screw rod 410 and a mobile motor 430. The mounting member 100 is provided with a slide rail 120. The mobile motor 430 is connected to the screw rod 410 by driving. The slider 420 is fixed to the flip driving module 300. The slider 420 is slidably sleeved on the screw rod 410. The flip driving module 300 is slidably connected to the slide rail 120. It can be understood that the mobile motor 430 is connected to the screw rod 410 by driving as a power source. The screw rod 410 pulls the slider 420 to move in the extension direction of the screw rod 410, that is, the flip driving module 300 is driven to move synchronously on the slide rail 120, and then the display 200 is moved synchronously with the slider 420 along the extension direction of the screw rod 410. In this way, the slide rail 120 on the mounting member 100 provides a stable moving path for the flip driving module 300 and the display 200, ensuring the stability and accuracy of the display 200 during the movement. At the same time, by precisely controlling the rotation speed and direction of the moving motor 430, the moving speed and direction of the display 200 can be precisely controlled, which helps to realize the automatic sliding of the display 200 in the vehicle environment to adjust the position, thereby meeting the viewing needs of the driver and passengers. Of course, in other embodiments, the display 200 or the flip driving module 300 can also be driven to move by a cylinder or a hydraulic cylinder.

[0055] Further, in this embodiment, please refer to Figure 1 and Figure 2 The mounting member 100 is also provided with a fixed block 140, and the fixed block 140 is provided with a bearing. The end of the screw rod 410 away from the moving motor 430 rotates and is inserted into the bearing of the fixed block 140. It can be understood that the screw rod 410, as a transmission element, needs to withstand the axial force and radial force from the moving motor 430 and the flip drive module 300 during operation. The bearing is provided on the fixed block 140, which can provide a stable support point for the screw rod 410, thereby effectively balancing the force applied to the screw rod 410 during operation and preventing the screw rod 410 from bending or deforming due to uneven force. At the same time, after the bearing is installed on the fixed block 140, the screw rod 410 can rotate freely in the bearing without overcoming excessive friction, which can reduce the energy loss of the screw rod 410 during rotation and improve the transmission efficiency. Of course, in other embodiments, the end of the screw rod 410 can also be coaxially connected to the motor shaft of the moving motor 430, and the other end is a free end, and the force support of the flip drive module 300 is achieved by the embracing sliding connection between it and the slide rail 120.

[0056] In one embodiment, please refer to Figure 1 and Figure 2The mounting member 100 is provided with a position detection member 130, which is adjacent to the end of the screw rod 410 away from the moving motor 430, and the position detection member 130 is used to detect the moving reversing position of the display 200. It should be noted that the position detection member 130 can accurately detect the specific position of the display 200 or the flip driving module 300 during the movement process. When the display 200 or the flip driving module 300 moves to the preset reversing position, the position detection member 130 will send a signal, and the moving driving module 400 will control the rotation direction of the screw rod 410 according to the signal to ensure that the display 200 can move in a predetermined direction and speed, thereby avoiding the display 200 from moving too much, thereby preventing the lock tongue or decorative accessories for locking the display 200 or the display 200 itself from being damaged. Of course, in other embodiments, the screw rod 410 can also be configured as a reciprocating screw rod 410 to meet the reverse movement of the specific position of the display 200.

[0057] Regarding the connection method between the flip driving module 300 and the rotating shaft 210 of the display 200, in one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The flip driving module 300 is provided with an output shaft 330, the rotating shaft 210 includes a rotating shaft body 211 and a coupling cover 214, the rotating shaft body 211 is provided with a mounting flat position 213, the coupling cover 214 is adapted to be mounted on the mounting flat position 213, and the output shaft 330 is sandwiched between the coupling cover 214 and the mounting flat position 213. It can be understood that the output shaft 330 and the rotating shaft 210 are formed separately, and the coupling cover 214 is adapted to be mounted on the mounting flat position 213 so that the output shaft 330 and the rotating shaft 210 are coaxially connected. When maintenance or replacement of parts is required, the coupling cover 214 can be easily removed to check the connection between the output shaft 330 and the rotating shaft 210. Among them, the installation flat position 213 provided on the rotating shaft body 211 can make the coupling cover 214 stably clamp the output shaft 330 between the rotating shaft body 211 and the coupling cover 214, so as to ensure the connection stability of the output shaft 330 and the rotating shaft 210, and avoid the eccentric rotation of the rotating shaft 210 relative to the output shaft 330. It is not general that the output shaft 330 and the rotating shaft 210 are penetrated with a pin rod 216 in the radial direction to ensure that the output shaft 330 and the rotating shaft 210 will not loosen or fall off due to vibration or external force, so as to achieve stable synchronous and coaxial rotation. Of course, in other embodiments, a socket can also be provided in the axial middle part of one of the rotating shaft 210 and the output shaft 330, and the other can be inserted into the socket, and then locked with the pin rod 216 from the radial direction to ensure the stability of synchronous rotation.

[0058] In one embodiment, please refer to Figure 2 and Figure 4A through hole 212 is provided in the axial middle of the rotating shaft 210, and an avoidance groove 215 is provided on the outer periphery of the rotating shaft 210. The avoidance groove 215 extends along the circumferential direction of the rotating shaft 210. A conductive line electrically connected to the display 200 is passed through the through hole 212. The avoidance groove 215 is provided corresponding to the end side of the outlet line of the through hole 212 and is connected to the through hole 212. The conductive line is connected to the outside through the avoidance groove 215. It can be understood that the through hole 212 in the middle of the rotating shaft 210 provides a channel for the conductive line to pass through the rotating shaft 210, so that the conductive line can pass through the inside of the rotating shaft 210 and connect to an external device or power supply, which can prevent the rotation of the display 200 from pulling the conductive line, thereby preventing the conductive line from being stuck or broken. Correspondingly, the avoidance groove 215 arranged on the outer periphery of the rotating shaft 210 is connected to the through hole 212 at the end side of the conductive wire for turning and exiting the wire. In this way, when the conductive wire passes through the through hole 212, it is ensured that the conductive wire smoothly transitions in the avoidance groove 215 to avoid the conductive wire being excessively bent or squeezed around the rotating shaft 210. In addition, the avoidance groove 215 extending circumferentially along the rotating shaft 210 reduces the friction and wear on the conductive wire during the rotation of the rotating shaft 210, thereby protecting the integrity and service life of the conductive wire. Without loss of generality, in combination with the above description of the shaft body 211 and the coupling cover 214, the through hole 212 is provided on the shaft body 211, and the avoidance groove 215 is provided on the coupling cover 214, then the avoidance groove 215 passes through the end of the shaft 210 along the axial direction of the shaft 210, and when the coupling cover 214 is connected to the shaft body 211, it will not interfere with the conductive wire, thereby improving the operational convenience of connecting the shaft 210 and the output shaft 330; at the same time, the shaft body 211 is provided with a limiting tongue 217 on the side facing the installation flat position 213, and the limiting tongue 217 is inserted into the position where the avoidance groove 215 passes through the end of the shaft 210, so that the conductive wire can be reversed and passed through the avoidance groove 215 at the end side of the through hole 212, that is, the conductive wire is connected to the outside at a position close to the center between the transmission member 320 and the display 200, thereby reducing the possibility of interference between the conductive wire and other components. Of course, in other embodiments, a guide groove may be axially recessed on the outer circumference of the rotating shaft 210 , and the conductive wire may be fitted in the guide groove so as to be connected to the display 200 through the guide groove.

[0059] In one embodiment, please refer to Figure 4The rotating shaft 210 is formed with a traction plate 218 at one end away from the flip driving module 300. The traction plate 218 is parallel to the screen of the display 200. During the rotation of the rotating shaft 210, the traction plate 218 can stably pull the display 200 to rotate, so as to ensure the reliability of the flipping of the display 200. The traction plate 218 extends from the end of the rotating shaft 210 toward the side of the display 200 away from the rotating shaft 210, so that the traction plate 218 can be close to the middle of the display 200. It can be known from the lever relationship that as the distance between the middle of the traction plate 218 and the rotating shaft 210 increases, the flip driving module 300 can flip the display 200 with a smaller driving force, thereby reducing the power requirement for the flip motor 310.

[0060] In one embodiment, please refer to Figure 1 and Figure 5 The vehicle-mounted display device includes two flip drive modules 300 and two mobile drive modules 400. A flip drive module 300 and a mobile drive module 400 are both located at one end of the rotating shaft 210 and are driven and connected to the corresponding end of the rotating shaft 210. It can be understood that the two flip drive modules 300 or two mobile drive modules 400 located at both ends of the rotating shaft 210 can simultaneously apply a flipping torque or a moving torque to the display 200, which helps to maintain the balance and stability of the display 200 during the flipping process or the moving process, and reduce the shaking or swaying that may be caused by unilateral driving. At the same time, the flip drive module 300 and the mobile drive module 400 can more effectively distribute the torque required for flipping, reduce the load of each drive module, extend its service life, and improve the accuracy and stability of the flipping action or the moving action, and reduce the operating noise of the flip drive module 300 and the mobile drive module 400. In addition, the above-mentioned dual-sided driving method also helps to reduce the risk of failure caused by unilateral overload or wear. When a problem occurs in the driving module on one side, the other side can still maintain the basic functions of the display 200, thereby improving the reliability and durability of the equipment.
