Description

Technical Field

[0001] The present invention relates to a display device for a vehicle interior space. Background Art

[0002] Some vehicles are equipped with a sky screen (also known as a ceiling screen) on the vehicle ceiling in the interior space. The display screen can be stored parallel to the vehicle ceiling in the retracted state, and in the opened state, it extends nearly vertically for vehicle occupants to view information such as entertainment and navigation.

[0003] Some existing sky screens are provided with a locking motor to lock the display screen in the retracted state so that it cannot rotate, thereby keeping it from shaking up and down even when the vehicle is driving bumpily. However, on the one hand, this significantly increases the cost due to the addition of the motor, and on the other hand, there will be a locking noise when locking the display screen after it is retracted, making the occupants feel uncomfortable.

[0004] Some other sky screens do not have a locking motor and rely only on the mechanical resistance of the drive motor and the transmission path itself for locking. Although this has a lower cost, due to, for example, the matching clearance on the transmission path, the display screen shakes significantly when the vehicle is driving bumpily in the retracted state. Summary of the Invention

[0005] The object of the present invention is to provide a display device for a vehicle interior space, which can at least solve one of the above-mentioned problems.

[0006] To achieve the above object, the present invention provides a display device for a vehicle interior space, characterized in that the display device includes a display screen and a control system capable of manipulating the display screen to move between a retracted position and an opened position, wherein the control system includes:

[0007] A display screen bracket fixedly connected to the display screen;

[0008] A first component configured as a slider, the slider being rotatably connected to the display screen bracket through a first rotational connection pair;

[0009] A second component configured as a connecting rod, the connecting rod being rotatably connected to the display screen bracket through a second rotational connection pair; and

[0010] A third component, the third component being rotatably connected to the connecting rod through a third rotational connection pair, and the slider and the third component being able to move relative to each other,

[0011] wherein, through the relative movement of the slider and the third component, the display screen bracket can be driven to rotate, so as to drive the display screen to switch between a retracted position and an opened position.

[0012] Among them, at least one of the first rotational connection pair, the second rotational connection pair, and the third rotational connection pair is provided with a locking-unlocking structure pair. The locking-unlocking structure pair has a locking position and an unlocking position. In the locking position, relative rotation of the at least one rotational connection pair is prohibited, thereby prohibiting rotation of the display screen bracket. In the unlocking position, relative rotation of the at least one rotational connection pair is allowed, thereby allowing rotation of the display screen bracket.

[0013] By providing a locking-unlocking structure pair on the rotational connection pair between correspondingly relatively rotatably connected components, the display device of the present invention can achieve mechanical locking of the rotational movement of the display screen bracket and thus the display screen in the retracted state of the display screen, thereby reliably and at low cost prohibiting the display screen from moving up and down due to vehicle bumps in the retracted state.

[0014] Advantageously, by relative movement of the slider and the third component, conversion of the locking-unlocking structure pair between the locking position and the unlocking position is achieved.

[0015] Advantageously, the locking-unlocking structure pair includes a locking-unlocking groove and a locking portion inserted into the locking-unlocking groove. The locking-unlocking groove has a locking groove portion and an unlocking groove portion. Wherein, in the locking position of the locking-unlocking structure pair, the locking portion is in the locking groove portion of the locking-unlocking groove to prohibit relative rotation of the locking portion and the locking-unlocking groove in a form-fitting manner. In the unlocking position of the locking-unlocking structure pair, the locking portion is in the unlocking groove portion of the locking-unlocking groove to allow relative rotation of the locking portion and the locking-unlocking groove.

[0016] Advantageously, the locking groove portion and the unlocking groove portion of the locking-unlocking groove are adjacent to each other and open towards each other, such that the locking portion can move from the locking groove portion of the locking-unlocking groove into the unlocking groove portion for unlocking, and can move from the unlocking groove portion of the locking-unlocking groove into the locking groove portion for locking.

[0017] Advantageously, the locking groove portion of the locking-unlocking groove has at least two parallel boundary walls, and the locking portion has at least two parallel locking surfaces. In the locking position of the locking-unlocking structure pair, the locking surfaces of the locking portion respectively abut against the boundary walls of the locking groove portion of the locking-unlocking groove. Here, in the locking position, since the two parallel locking surfaces respectively abut against the two parallel boundary walls, rotation prohibition of the locking portion in the locking groove portion can be most simply achieved in a form-fitting manner, but the locking portion is allowed to move (or translate) into or out of the locking groove portion.

[0018] Advantageously, a rotation support groove is provided axially offset from the locking-unlocking groove, and a rotation support portion is provided axially offset from the locking portion. In the unlocking position of the locking-unlocking structure pair, the rotation support portion is rotatably supported in the rotation support groove. Here, although rotation support of the locking portion therein can also be achieved if the unlocking groove portion has sufficient axial thickness, the rotation support groove and the rotation support portion provided here can play a good role in assisting rotation support, making the rotation smoother.

[0019] Advantageously, the at least one rotation connection pair includes a shaft hole and a rotation shaft inserted into the shaft hole, the locking-unlocking groove is configured as the shaft hole or a part thereof, and the locking portion is configured as the rotation shaft or a bushing mounted on the rotation shaft, or a part of the rotation shaft or the bushing.

[0020] Advantageously, the rotation shaft is provided on one of the display screen bracket and the slider, and the shaft hole is provided on the other of the display screen bracket and the slider; or,

[0021] the rotation shaft is provided on one of the display screen bracket and the connecting rod, and the shaft hole is provided on the other of the display screen bracket and the connecting rod; or,

[0022] the rotation shaft is provided on one of the connecting rod and the third component, and the shaft hole is provided on the other of the connecting rod and the third component.

[0023] Advantageously, an auxiliary support groove is provided on one of the slider and the display screen bracket, and an auxiliary support protrusion is provided on the other of the slider and the display screen bracket. The auxiliary support groove and the auxiliary support protrusion are arranged at an interval from the first rotation connection pair. Among them, the auxiliary support groove has a support groove portion and a release groove portion adjacent to the support groove portion. In the locking position of the locking-unlocking structure pair, the auxiliary support protrusion is located in the support groove portion of the auxiliary support groove to form a positive locking to assist in prohibiting the rotation of the display screen bracket, and when the locking-unlocking structure pair enters the unlocking position, the auxiliary support protrusion enters the release groove portion of the auxiliary support groove to allow the rotation of the display screen bracket.

[0024] Advantageously, the auxiliary support protrusion is provided as an extension of the shoulder of the connecting rod for connecting to the display screen bracket. This can simplify the structure, and the shoulder can not only act as a rotation shaft between the connecting rod and the display screen bracket but also act as an auxiliary support protrusion.

[0025] Advantageously, the operating system further includes a slide rail assembly and a trolley assembly configured as the third component, the trolley assembly is connected to the slide rail assembly in a relatively movable manner, and the slider is connected to the trolley assembly in a relatively movable manner.

[0026] Advantageously, the trolley assembly and the slider can be driven independently of each other.

[0027] Advantageously, the slider and the trolley assembly are connected to each other by a guiding mechanism pair, and the guiding mechanism pair ensures that the slider moves along the trolley assembly in only one degree of freedom.

[0028] Advantageously, the guiding mechanism pair includes a sleeve provided on one of the slider and the trolley assembly and a guiding rod provided on the other of the slider and the trolley assembly, and / or includes a sliding boss provided on one of the slider and the trolley assembly and a long groove provided on the other of the slider and the trolley assembly.

[0029] Advantageously, the trolley assembly includes a trolley component and a bracket component fixedly connected to each other, the trolley component is connected to the slide rail assembly, and the bracket component is connected to the slider and the connecting rod.

[0030] Advantageously, the operating system further includes a slide rail assembly configured as the third component, and the slider is connected to the slide rail assembly in a relatively movable manner.

[0031] Advantageously, the display device is provided on the vehicle ceiling, and the display screen is arranged in or on the vehicle ceiling parallel to the vehicle ceiling in the retracted position, and is inclined to the vehicle ceiling in the opened position. Description of the Drawings

[0069] The terms and phrases used herein should be understood and interpreted to have the same meaning as that understood by those skilled in the relevant art for these terms and phrases. The consistent use of the terms or phrases herein does not imply a special definition of the terms or phrases, that is, a definition different from the ordinary and customary meaning understood by those skilled in the art. For terms or phrases intended to have a special meaning, that is, a meaning different from that understood by the skilled person, such special definition will be clearly listed in the specification in a definitional manner, directly and unambiguously giving the special definition of the term or phrase.

[0070] Unless required by the content, throughout the following specification, the word "comprising" and its variants, such as "including" and "having", will be interpreted in an open, inclusive sense, that is, as "including but not limited to".

[0071] The display device 1 for the vehicle interior space of the present invention can be provided on the vehicle ceiling, for example, behind a row of seats, such as between the first row and the second row of seats. However, it is also conceivable that this display device 1 is provided at other positions outside the vehicle ceiling in the vehicle interior space, such as on the instrument panel, on the center console, on the back of the seat back, etc.

[0072] The display device 1 of the present invention has a mechanical locking function, so that the display screen 2 can be locked and non-rotatable in the retracted state to prevent the display screen 2 from shaking up and down towards and away from the vehicle ceiling 3, especially during bumpy driving of the vehicle.

[0073] The vehicle of the present invention can be an automobile, such as a sedan or a commercial vehicle, etc. Next, a vehicle x-y-z coordinate system is established according to the commonly used technical means in the field of automotive engineering to facilitate the subsequent description of the relative positions of the various parts in the present invention.

[0074] Next, different embodiments of the display device 1 for the vehicle interior space of the present invention will be described exemplarily.

[0075] Figures 1a to 14d Schematically shows the display device 1 for the vehicle interior space according to the first embodiment of the present invention. Refer to Figure 1a , the display device 1 can include a display screen 2 extending in the vehicle y-direction for playing entertainment, navigation and other information to the occupants, and a display screen control system for manipulating the display screen 2 to move in the vehicle x-direction along the vehicle ceiling 3 and rotate between its retracted position and open position.

[0076] Figure 1a The display screen 2 in is in a forward position and in the retracted position. Compared with Figure 1a , Figure 1b shows that the display screen 2 has moved backward a certain distance but is still in the retracted position. And compared with Figure 1b , Figure 1c shows that the display screen 2 has rotated from the retracted position to the open position. For example, for the second-row occupants when the vehicle seat is adjusted to the reclined or zero-gravity position, this rear open position of the display screen 2 is a more comfortable viewing position.

[0077] Different from Figures 1a to 1c where the display screen 2 moves first and then rotates, Figures 2a to 2c shows the sequence where the display screen 2 rotates first and then moves. It is conceivable that the movement sequence of the display screen 2 can be freely selected by the occupants and realized through a wireless or wired control system.

[0078] Figure 3a and Figure 3b respectively show partial components of the operating system on one side (i.e., the left side) of the display screen 2 in the assembled state diagram and the disassembled state diagram of the display device 1. It can be conceived that the operating system may be provided with the same and opposing components on the other side (i.e., the right side) of the display screen 2. Generally speaking, on each side of the display screen 2, the operating system may include (looking inward from the y-direction outward) a slide rail assembly 4 fixed relative to the ceiling 3 or the ceiling trim (which has a slide rail 40), a trolley assembly 5 movably connected to the slide rail assembly 4, a slider 6 movably connected to the trolley assembly 5, a display screen bracket 7 movably connected to the slider 6, and a connecting rod 8 movably connected to the display screen bracket 7 and the trolley assembly 5.

[0079] See Figure 4a and Figure 4b , the trolley assembly 5 may include a trolley component 51 and a bracket component 52 that are independent of each other and fixedly connected. It can also be conceived that the trolley component 51 and the bracket component 52 are integrally formed.

[0080] The trolley component 51 may be formed in a long shape and can be movably supported in the receiving portion 41 of the slide rail assembly 4 (see Figure 8 ). The trolley component 51 may have damping structures 511 at the portions where it contacts the inner wall of the receiving portion 41, here on its two sides and above. The damping structures 511 may be formed as arched elastic pieces here. The damping structures 511 are designed such that the trolley component 51 can be stably supported in the receiving portion 41 but still slide in the receiving portion 41 without being jammed. The trolley component 51 may have a trolley-cable fixing portion 512 at its approximately central position. A cable 513 for driving the trolley assembly 5 to move in the x-direction (see Figure 7b ) may be fixedly connected to the trolley-cable fixing portion 512. For example, one end of the cable 513 penetrates and is riveted to the trolley-cable fixing portion 512. And the other end of the known cable 513 may be connected to a trolley drive motor assembly (not shown) and can be driven by it. The trolley drive motor assembly may be designed to synchronously drive two cables 513, and these two cables 513 are respectively connected to two trolley assemblies 5 on both sides of the display screen 2 so that the two trolley assemblies 5 move synchronously. See Figure 8 and Figure 9 , the trolley-cable fixing portion 512 on the trolley component 51 together with the cable 513 may be received and extended in the slide rail assembly 4. Here, it can be conceived that the trolley-cable fixing portion 512 may also be fixed at any other suitable position on the trolley assembly 5 as long as it can be used to drive the movement of the trolley assembly 5 relative to the slide rail assembly 4.

[0081] The support member 52 may have an integrally formed lateral portion 521 and a vertical portion 522. The support member 52 may be fixedly connected, for example, screwed, to the pulley member 51 by using its lateral portion 521. A long slot may be provided on the lateral portion 521 and a guide rod 5211 fixedly extending thereon, such as an extruded aluminum rod (see Figure 6 ), and the guide rod 5211 may be fixedly connected to the lateral portion 521 by means of screws, for example. A pre-tightening stamping spring piece 5212 may be provided above the guide rod 5211 on the lateral portion 521 (see Figure 6 ).

[0082] The vertical portion 522 of the support member 52 may be provided with a long slot 5221 extending in the x direction and a connecting rod connection hole 5222 spaced from the long slot 5221 by distances in the x direction and the z direction at the front end. The front end connection post 84 of the connecting rod 8 may be pivotally connected to the connecting rod connection hole 5222 by means of an M6 bolt 85, for example (see Figure 3a and Figure 3b 、 Figure 4a and Figure 4b ). Here, the connection post 84 on the connecting rod 8, the connecting rod connection hole 5222 on the support member 52, and the bolt 85 may jointly form a rotational connection pair between the connecting rod 8 and the pulley assembly 5, which only realizes the rotatable connection function of the connecting rod 8 on the support member 52 or the pulley assembly 5.

[0083] See Figures 6 to 7b , the slider 6 is relatively movably connected to the pulley assembly 5, specifically, to its support member 52. For this purpose, see Figure 5a , the slider 6 may be provided with a sleeve 61, such as an aluminum rail sleeve 61, and a sliding boss 62 on its outer side in the y direction. The sleeve 61 may be sleeved on the guide rod 5211 of the support member 52 and slide along it, while at the same time the sliding boss 62 may be embedded in the long slot 5221 of the support member 52 and slide along it. Through the cooperation of the sleeve 61 and the sliding boss 62 on the slider side (as a combined guiding mechanism on the slider side) with the guide rod 5211 and the long slot 5221 on the pulley assembly side (as a cooperating combined guiding mechanism on the pulley assembly side, which jointly forms a guiding mechanism pair with the combined guiding mechanism on the slider side), only allows the slider 6 to move relative to the pulley assembly 5 in only one degree of freedom in the x direction, without moving or deflecting in the y direction or the z direction.

[0084] In some embodiments, it is also conceivable to integrate the functions of the sleeve 61 and the sliding boss 62 on the slider side onto one guiding mechanism, and integrate the functions of the guiding rod 5211 and the elongated slot 5221 on the carriage assembly side onto one mating guiding mechanism to simplify the structure. For example, the one guiding mechanism can be designed as the T-shaped elongated slot 5221, and the one mating guiding mechanism is designed as the T-shaped sliding boss 62 that mates with the T-shaped elongated slot 5221, thereby eliminating the guiding rod 5211 and the sleeve 61. Or the one guiding mechanism is designed as a non-circular, for example, polygonal guiding rod 5211, and the one mating guiding mechanism is designed as a sleeve 61 with a non-circular inner wall, for example, a polygonal inner wall, that mates with the non-circular guiding rod 5211, thereby eliminating the elongated slot 5221 and the sliding boss 62.

[0085] See Figure 5a , the slider 6 can have a slider-cable fixing portion 63 on the outside of its sleeve 61. The cable 64 for driving the slider 6 in the x direction (see Figure 7b ) can be fixedly connected to the slider-cable fixing portion 63, for example, inserted and riveted to the slider-cable fixing portion 63. The other end of the cable 64, which is known per se, can be connected to a slider drive motor assembly (not shown) and can be driven thereby. The slider drive motor assembly can be designed to synchronously drive the two cables 64, which are respectively connected to the two sliders 6 on both sides of the display screen 2, so that the two sliders 6 move synchronously. See Figure 8 and Figure 9 , the slider-cable fixing portion 63 on the slider 6 together with the cable 64 can be accommodated and extended in the slide rail assembly 4. Here, it is conceivable that the slider-cable fixing portion 63 can also be fixed at any other suitable position on the slider 6 as long as it can be used to drive the movement of the slider 6 relative to the carriage assembly 5.

[0086] See Figure 5b and Figure 5c, the slider 6 can have a generally Z-shaped shape on its inner side in the y direction. The slider 6 can be provided with a shaft hole 60 at its rear upper part (the left upper part in the figure). The shaft hole 60 can include a locking-unlocking groove 65 in the form of a key, and the locking-unlocking groove 65 can have a locking groove part 651 and an unlocking groove part 652 that are adjacent to each other and open towards each other. The locking groove part 651 can be arranged in front of the unlocking groove part 652. The locking groove part 651 can be jointly defined by two flat horizontal walls that extend linearly and are parallel to each other up and down and an arc wall connecting the two, and these two horizontal walls and the arc wall respectively constitute the boundary walls for defining the locking groove part 651; while the unlocking groove part 652 can be defined by an arc wall greater than 180°. The shaft hole 60 can also include an elliptical rotation support groove 66, and the rotation support groove 66 can be arranged around the locking-unlocking groove 65 and be staggeredly arranged on the inner side in the axial direction (or the inner side in the y direction) of the locking-unlocking groove 65. The shaft hole 60 can also include a smaller elliptical mounting groove 67, and the mounting groove 67 can be arranged around the locking-unlocking groove 65 and be staggeredly arranged on the outer side in the axial direction (or the outer side in the y direction) of the locking-unlocking groove 65. Thus, the outermost mounting groove 67, the middle locking-unlocking groove 65, and the innermost rotation support groove 66 form a layer groove combination that is staggered in the y direction, and the slider 6 penetrates in the y direction at the shaft hole 60.

[0087] The slider 6 can be provided with an auxiliary support groove 68 at its front lower part (the right upper part in the figure) on its inner side in the y direction. The auxiliary support groove 68 can have a generally rectangular support groove part 681 in the front and a release groove part 682 adjacent to the support groove part 681 in the rear. The support groove part 681 is defined by horizontal and vertical walls on its upper side, lower side, and front side and is open towards the release groove part 682 at the rear; while the release groove part 682 is defined by an inclined wall at its rear and is open towards the outside at the lower side.

[0088] See Figure 3a , the display screen bracket 7 can be fixed on it parallel to or coplanar with the display screen 2, and their outer edges in the y direction can be arranged flush with each other.

[0089] See Figure 10a and Figure 10b, the display bracket 7 has, on its outer side in the y-direction, a slider joint 77 extending outward in the y-direction for rotatably connecting to the shaft hole 60 of the slider 6. The slider joint 77 may include a rotating shaft 70 and a bushing 71 fitted onto the rotating shaft 70 in a form-locking manner, and they can be inserted into the shaft hole 60 on the slider 6. Here, the rotating shaft 70 and the bushing 71 on the display bracket 7 and the shaft hole 60 on the slider 6 can jointly form a rotational connection pair between the display bracket 7 and the slider 6. Since the shaft hole 60 is provided with or includes a locking-unlocking groove 65 here, through this rotational connection pair, not only can the rotatable connection function of the display bracket 7 on the slider 6 be realized (the rotating shaft 70 and the bushing 71 are at this time in the unlocking groove portion 652 of the locking-unlocking groove 65), but also the connection function that prohibits the rotation of the display bracket 7 on the slider 6 can be realized (the rotating shaft 70 and the bushing 71 are at this time in the locking groove portion 651 of the locking-unlocking groove 65).

[0090] The bushing 71 may have a locking portion 711 on its outer side in the y-direction, and it may have two flat locking surfaces 7111 arranged parallel to each other and extending horizontally. The locking portion 711 of the bushing 71 can be inserted into the locking-unlocking groove 65 and move between the locking groove portion 651 and the unlocking groove portion 652 in the x-direction to achieve locking and unlocking. Specifically, the locking portion 711 of the bushing 71 can enter and lock in the locking groove portion 651 of the locking-unlocking groove 65 so that the display bracket 7 and thus the display 2 cannot rotate. At this time, the two locking surfaces 7111 of the bushing 71 respectively abut against the two horizontal walls of the locking groove portion 651 in a form-locking manner to achieve locking; and when the locking portion 711 of the bushing 71 moves into the unlocking groove portion 652, the rotation of the display bracket 7 and thus the display 2 is allowed. At this time, the two locking surfaces 7111 of the bushing 71 have disengaged from the form-locking contact with the two horizontal walls of the locking groove portion 651, and since the maximum diameter of the locking portion 711 is less than or equal to the diameter of the unlocking groove portion 652, it can rotate unrestrictedly in the unlocking groove portion 652.

[0091] The bushing 71 may have a rotating support portion 712 on the inner side of the locking portion 711 in the y-direction, and it may have a surrounding (closed or discontinuous) rotating support surface 7121. The diameter of the rotating support surface 7121 may be substantially equal to the height or the short axis length of the elliptical rotating support groove 66, so that the rotating support portion 712 can move in the rotating support groove 66 in the x-direction and can be supported to rotate by it.

[0092] Here, the slider joint 77 of the display screen bracket 7 is axially fixed in the shaft hole 60 of the slider 6 by means of a stepped screw 72. The stepped screw 72 can be successively inserted through the mounting groove 67, the locking-unlocking groove 65, and the rotation support groove 66 starting from the y-direction outer side of the slider 6, and is inserted and fixed in the rotation shaft 70 with a thin front step, and the thick rear step of the stepped screw 72 can be engaged in the mounting groove 67 for support and guidance.

[0093] See Figure 10b , the rear end of the connecting rod 8 for connecting to the display screen bracket 7 can be provided with two cylindrical shoulders 81 extending on both sides thereof (which serve as rotation shafts here), and a connecting rod bushing 82 (made of an elastic material, such as POM) can be sleeved on each of them respectively, and is rotatably fixed in the shaft hole 75 surrounded by the upper bracket part 73 and the lower bracket part 74 of the display screen bracket 7, so that the connecting rod 8 can pivot relative to the display screen bracket 7. Here, the shaft hole 75 on the display screen bracket 7, the cylindrical shoulders 81 on the connecting rod 8, and the connecting rod bushings 82 can jointly form a rotational connection pair between the display screen bracket 7 and the connecting rod 8, which only realizes the rotatable connection function of the connecting rod 8 on the display screen bracket 7 here. In addition, an auxiliary support protrusion 83 is connected to the shoulder 81 on the y-direction outer side, which can be configured as a rubber sleeve fixed to the shoulder 81 here. The auxiliary support protrusion 83 laterally protrudes from the display screen bracket 7 towards the auxiliary support groove 68, so that the auxiliary support protrusion 83 can be fitted into the auxiliary support groove 68 of the slider 6 and can move between the support groove part 681 and the release groove part 682, and can move away from the auxiliary support groove 68 from the release groove part 682.

[0094] The following will describe in combination with Figures 11a to 14d the cooperation mode of the above-mentioned various components during the process of the display screen 2 of the display device 1 moving from the retracted and locked state to the opened state.

[0095] Figure 11a , Figure 12a , Figure 13a , Figure 14a show the retracted and locked state of the display screen 2. At this time, the display screen bracket 7 and the display screen 2 are arranged parallel to the ceiling 3 (see Figure 11a ) and are locked by the locking-unlocking structure pair and will not rotate. At this time, the display screen 2 is firmly locked in its retracted state and will not shake up and down due to bumpy driving.

[0096] See Figure 12a and Figure 13a , the bushing 71 of the slider joint 77 of the display screen bracket 7 is engaged in the locking groove part 651 of the locking-unlocking groove 65. At the same time, see Figure 14a, the auxiliary support protrusion 83 of the connecting rod 8 enters and supports in the support groove portion 681 of the auxiliary support groove 68. Thus, the display screen bracket 7 is firmly supported on the slider 6, and the display screen bracket 7 and thus the display screen 2 are locked relative to the slider 6 in a non-rotatable manner. This locking relying only on the mechanical structure eliminates the locking motor, saves costs, and is mechanically reliable. In some embodiments, when the display screen 2 is smaller or lighter in weight, the auxiliary support of this pair of mechanical structures of the auxiliary support groove 68 of the slider 6 and the auxiliary support protrusion 83 of the connecting rod 8 can also be omitted, and the locking of the display screen 2 can be achieved only by relying on the locking of the slider joint 77 of the display screen bracket 7 in the locking groove portion 651 of the locking-unlocking groove 65.

[0097] Figure 11b , Figure 12b , Figure 13b , Figure 14b shows the retracted but unlocked state of the display screen 2. To reach this retracted but unlocked state from the above-mentioned retracted and locked state, it is only necessary to move the slider 6 (relative to the trolley assembly 5 and the display screen bracket 7) forward by a small distance, such as about 10 mm, through the slider drive motor, so that the slider joint 77 of the display screen bracket 7, or rather its bushing 71, moves from the locking groove portion 651 of the locking-unlocking groove 65 into the unlocking groove portion 652 (see Figure 11b , Figure 12b and Figure 13b ), and at the same time, the auxiliary support protrusion 83 of the connecting rod 8 also moves from the support groove portion 681 of the auxiliary support groove 68 into the release groove portion 682 (see Figure 12b and Figure 14b ).

[0098] Continuing to move the slider 6 forward, the display screen bracket 7 together with the display screen 2 begins to rotate clockwise to open. Figure 11c , Figure 12c , Figure 13c , Figure 14c shows an intermediate state during the opening process of the display screen 2. The slider joint 77 of the display screen bracket 7 remains in the unlocking groove portion 652 of the locking-unlocking groove 65 (see Figure 11c , Figure 12c and Figure 13c ) and rotates. At the same time, the auxiliary support protrusion 83 of the connecting rod 8 pivots away from the release groove portion 682 of the auxiliary support groove 68 as the connecting rod 8 pivots downward (see Figure 14c ).

[0099] Continuing to move the slider 6 forward until reaching Figure 11d , Figure 12d , Figure 13d , Figure 14dThe open state of the display screen 2 shown. At this time, the display screen 2 is already close to the vertical viewing state. In this open state, the occupant can comfortably view the content played on the display screen 2. The slider joint 77 of the display screen bracket 7 still remains in the unlocking groove portion 652 of the locking-unlocking groove 65 (see Figure 11d , Figure 12d and Figure 13d ), and reaches the maximum rotation angle. At the same time, the auxiliary support protrusion 83 of the connecting rod 8 has also moved away from the auxiliary support groove 68 at most as the connecting rod 8 pivots downward (see Figure 14d ).

[0100] So far, the transformation of the display screen 2 from the retracted and locked state to the open state has been achieved. The entire operation process is very simple, that is, only by continuously pushing the slider 6 forward can the unlocking and opening of the plane be achieved successively. It can be imagined that the process of transforming the display screen 2 from the open state to the retracted and locked state is the reverse process of the above process, that is, only by continuously pushing the slider 6 backward in the reverse direction.

[0101] In addition, as Figures 1a to 2c shown, whether in the retracted state or the open state of the display screen 2, the display screen 2 can be moved in the x direction by moving the trolley assembly 5. When it is necessary to move the display screen 2 in the x direction, the trolley drive motor and the slider drive motor can work simultaneously to drive the trolley assembly 5 and the slider 6 to move synchronously in the same direction. When it is necessary to unlock and rotate the display screen 2, a relative movement in the x direction is required between the trolley assembly 5 and the slider 6. This can be achieved, for example, by driving the slider 6 to move relative to the trolley assembly 5 by the slider drive motor as described above. In addition, it can also be imagined that this can be achieved by driving the trolley assembly 5 and the slider 6 to move synchronously in the reverse direction by the trolley drive motor and the slider drive motor respectively.

[0102] In some embodiments not shown, the components of the display device 1 in the above first embodiment can be arranged mirror-image with respect to a mirror surface extending in the y direction. At this time, the display screen bracket 7 and the slider 6 are arranged in front of the connecting rod 8. The rotation direction of the display screen 2 when it is opened is opposite to that of the first embodiment.

[0103] In some embodiments not shown, the locking-unlocking structure pair can be additionally or alternatively provided on the rotational connection pair between the connecting rod 8 and the trolley assembly 5. That is to say, the connecting column 84 on the connecting rod 8, the connecting rod connection hole 5222 on the bracket member 52 and the bolt 85 are replaced with a rotating shaft 70 with a locking portion 711, a shaft sleeve 71 and a shaft hole 60 with a locking-unlocking groove 65. Thus, through the rotational connection pair between the connecting rod 8 and the trolley assembly 5, not only the rotatable connection function of the connecting rod 8 on the trolley assembly 5 can be realized, but also the non-rotatable connection function of the connecting rod 8 on the trolley assembly 5 can be realized. At this time, the unlocking and opening process of the display screen can also be carried out as in the first embodiment.

[0104] Figures 15 to 24b The display device 1 showing the second embodiment of the present invention is described below. Next, the differences between the second embodiment and the first embodiment will be mainly described. In this second embodiment, the slider joint 77 of the display screen bracket 7 is designed to be directly hinged to the slider 6 in a rotatable but non-movable manner, and no locking-unlocking structure pair is provided at this hinge point. However, a locking-unlocking structure pair is provided at the rotational connection pair where the connecting rod 8 is connected to the display screen bracket 7. Thus, through the rotational connection pair between the connecting rod 8 and the display screen bracket 7, not only the rotatable connection function of the connecting rod 8 on the display screen bracket 7 can be realized, but also the connection function that prohibits the rotation of the connecting rod 8 on the display screen bracket 7 can be realized. Refer to Figure 17 and Figure 18 , bushing 71 is respectively provided on the two lateral shoulders 81 of the connecting rod 8 as the rotation axis, and these two bushings 71 face each other and are respectively provided with their own locking portions 711 and rotational support portions 712 (refer to Figure 22 ). Correspondingly, refer to Figure 19 and Figure 20 , the shaft holes 75 formed by the upper bracket portion 73 and the two lower bracket portions 74 of the display screen bracket 7 respectively have locking-unlocking grooves 65 and rotational support grooves 66. Similar to the first embodiment, each locking-unlocking groove 65 may also include a locking groove portion 651 and an unlocking groove portion 652. When the locking portion 711 of the bushing 71 of the connecting rod 8 is in the locking groove portion 651 of the locking-unlocking groove 65 of the display screen bracket 7, the display screen bracket 7 is locked and cannot rotate. When the locking portion 711 of the bushing 71 of the connecting rod 8 is in the unlocking groove portion 652 of the locking-unlocking groove 65 of the display screen bracket 7, the display screen bracket 7 is unlocked and can rotate. In the present invention, it is also conceivable that the rotation axis may not be provided with a bushing, but the locking portion and the rotational support portion are directly provided on the rotation axis.

[0105] Figure 24a Respectively show the positions of the two bushings 71 of the connecting rod 8 in the display screen bracket 7 in the locked state of the display screen bracket 7. Figure 24b Respectively show different positions of the two bushings 71 of the connecting rod 8 in the display screen bracket 7 in the unlocked state of the display screen bracket 7. When changing from the Figure 24a shown locked state to the Figure 24b shown unlocked state, the slider 6 can also be moved forward a small distance relative to the trolley assembly 5. At the same time, the slider 6 synchronously drives the display screen bracket 7 to also move forward this small distance through the slider joint 77, so that the two bushings 71 of the connecting rod 8 enter the unlocking groove portion 652 from the locking groove portion 651 of the locking-unlocking groove 65 of the display screen bracket 7, realizing the unlocking of the display screen bracket 7. Continuing to move the slider 6 forward can cause the display screen 2 to rotate from the retracted state to the opened state.

[0106] In addition, referring again to Figure 17 and Figure 18 , a foam sheet 86 is provided between the connecting rod 8 and each bushing 71 to limit the bushing 71 in the y direction. Additionally, similar to the first embodiment, an auxiliary support protrusion 83 is also connected to the convex shoulder 81 on the outer side in the y direction. The auxiliary support protrusion 83 can be fitted into the auxiliary support groove 68 of the slider 6 to assist in supporting the display screen bracket 7. The auxiliary support groove 68 is open on the entire rear side here to allow the auxiliary support protrusion 83 to move out of the auxiliary support groove 68 when unlocking.

[0107] Figure 25 A special embodiment of the display device 1 is shown. The operating system of the display device 1 omits the above-described locking-unlocking structure pair, that is, the display screen bracket 7, the slider 6, and the connecting rod 8 are only rotatably connected at the joint part without relative movement unlocking. Here, the angle α between the connecting rod 8 and the horizontal plane (or the display screen 2) is set to be greater than 30°. Under this setting, the above-mentioned locking-unlocking groove 65 and auxiliary support groove 68 can be cancelled, and the relative self-locking effect can be achieved only by the angle structure formed between the connecting rod 8 and the display screen bracket 7. This self-locking effect can already prevent the display screen 2 from moving up and down easily during bumpy driving. The arrangement of the connecting rod 8 requires a relatively large z-direction height, so the display device 1 can be used in some scenarios with sufficient z-direction space, such as a motorhome, a bus, etc. In other embodiments, when the z-direction space is limited, the angle between the connecting rod 8 and the horizontal plane is less than 30°, and it is difficult to achieve the self-locking effect, so the locking-unlocking structure pair of the present invention is provided. Of course, it can be conceived that even in this special embodiment, the locking-unlocking structure pair of the present invention can be additionally provided to increase the locking-unlocking function of the present invention.

[0108] Figures 26a to 33 A display device 1 according to the third embodiment is shown. In this third embodiment, referring to Figure 26a and Figure 26b , only the rotation and opening / closing function of the display screen 2 is realized, and the x-direction movement function of the display screen 2 is not provided. Therefore, in this third embodiment, the trolley assembly 5 can be omitted, and the slider 6 is directly movably connected to the slide rail assembly 4. Generally speaking, in this third embodiment, the operating system on each side of the display screen 2 can include (looking inward from the outer side in the y direction) a slide rail assembly 4 fixed relative to the ceiling 3 or the ceiling trim, a slider 6 movably connected to the slide rail assembly 4, a display screen bracket 7 movably connected to the slider 6, and a connecting rod 8 movably connected to the display screen bracket 7 and the slide rail assembly 4.

[0109] Referring to Figure 27b, the front end connecting column 84 of the connecting rod 8 is rotatably inserted into the shaft hole 41 on the slide rail assembly 4. Here, the connecting column 84 on the connecting rod 8 and the shaft hole 41 on the slide rail assembly 4 can jointly form a rotational connection pair between the connecting rod 8 and the slide rail assembly 4 that only has a rotational connection function here. A rotational support member 42 is also provided here to assist in the rotational support of the connecting column 84. The rear end of the connecting rod 8 is still rotatably connected to the display screen bracket 7 as in the first embodiment. The display screen bracket 7 can still be connected to the slider 6 through a locking-unlocking structure pair as in the first embodiment. However, it is also conceivable to combine the locking-unlocking structure pair in this third embodiment with those in the above-mentioned various embodiments.

[0110] See Figure 30 , the guiding mechanism of the slider 6 on the slide rail assembly 4 may include: a substantially T-shaped slide rail matching boss 69.1, which has two thin tabs on both sides and can be accommodated and slide in the receiving groove of the slide rail assembly 4; and a sliding boss 62, which can still be embedded in the long groove 5221 of the bracket member 52 and slide along it. Both the slide rail matching boss 69.1 and the sliding boss 62 jointly maintain the stable support of the slider 6 relative to the slide rail assembly 4. The bracket member 52 can be formed separately and fixed on the slide rail assembly 4 here, but it is also conceivable that the bracket member 52 is configured as a part of the slide rail assembly 4, for example, directly providing the long groove 5221 on the slide rail assembly 4.

[0111] See Figure 31 , the guiding mechanism of the slider 6 on the slide rail assembly 4 can also include the following slide rail matching boss 69.2, which is different from Figure 30 the shown embodiment, but has relatively thick rectangular blocks on both sides, which can support the slider 6 on the slide rail assembly 4 more stably. Additionally, the slider-soft shaft fixing portion 63 on the slider 6 and the soft shaft 64 inserted therein, as well as the damping structure 511, can be seen.

[0112] In Figure 32 it can be seen Figure 31 the installation state of the slider 6 on the slide rail assembly 4, and the assembly states of other components of the operating system with each other.

[0113] In Figure 33 it is shown Figure 31 a transverse cross-sectional view of, but the slider 6 is not shown. Here, the auxiliary support protrusion 83 on the display screen bracket 7 is fitted into the auxiliary support groove 68 of the slider 6. In the present invention, it is also conceivable that, in addition to being connected to the cylindrical shoulder 81 of the connecting rod 8, the auxiliary support protrusion 83 can also be provided on the y-direction outer side wall of the display screen bracket 7.

[0114] Finally, it should be pointed out that the above-mentioned various embodiments are only used to understand and explain the present invention, and do not limit the protection scope of the present invention. For those skilled in the art, modifications or recombinations can be made on the basis of the above embodiments, and they all do not depart from the protection scope of the present invention.
