[0044] Combine Figure 1 and Figure 2As shown, an embodiment of the present application provides an office desk comprising a desk body 1 and a projection assembly 3. The desk body 1 is provided with a projection board 2, which is foldably connected to the desk body 1, allowing the projection board 2 to fit snugly against the desk body 1 or to unfold relative to the desk body 1. The unfolded projection board 2 can be used for projecting images. The projection assembly 3 includes a projector 31 and a telescopic mechanism. Projector 31 is a device used to project images onto a screen. The desk body 1 is provided with a mounting slot that matches the structure of projector 31. "Matching" in this context means that the dimensions of projector 31 are the same or similar to those of the mounting slot. Projector 31 is positioned within the mounting slot to accommodate projector 31. Projector 31 is connected to the desk body 1 via the telescopic mechanism, which allows the projector 31 to be extended from the mounting slot or retracted back into the slot. The telescopic mechanism is used to drive projector 31 out of the mounting slot. When projected out of the mounting slot, the lens of projector 31 is aligned with the unfolded projection board 2. Projector 31 is used to project images onto the unfolded projection board 2.

[0045] The office desk provided in this application allows the table body 1 to be used as an office desk by folding the projection board 2 and retracting the projector 31. By unfolding the projection board 2 and driving the projector 31 to extend out of the installation slot, the table body 1 can be used as a viewing device. The office desk integrates office and entertainment without occupying additional space, reducing the difficulty of planning the interior space of the vehicle.

[0046] In addition, in the related art, the monitor and the desk are designed separately. The desk is set in front of the seat inside the vehicle, and the monitor is generally installed at the corresponding position of the vehicle roof or on the partition in front of the seat. The monitor is used to play stored videos, and passengers cannot control it by themselves. The flexibility of use is poor, and it cannot play PPT, documents and other materials, and cannot meet the passengers' mobile office needs.

[0047] The office desk provided in this application adopts a projector 31 for projection, which can project mobile phone files and then project intended videos on the projection board 2. It can realize autonomous control by passengers, increase the flexibility of use, and can project PPT, documents and other materials to meet the mobile office needs of passengers.

[0048] In some embodiments, combined Figure 2 、 Figure 4 and Figure 5 As shown, the telescopic mechanism includes an electric push rod 32 , which has a telescopic rod connected to the projector 31 .

[0049] In this design, the projector 31 can be driven to move linearly by the electric push rod 32, thereby increasing the convenience of operation.

[0050] In other embodiments, the telescopic mechanism includes a drive motor, a gear, and a rack. Specifically, the projector 31 is connected to the rack, and the gear is provided on the output shaft of the drive motor. The gear and the rack are meshed, and the drive motor drives the gear to rotate, thereby driving the rack and the projector 31 to move linearly.

[0051] It can be seen that the design method of the telescopic mechanism of the present application is not limited and can be designed according to actual needs.

[0052] In some embodiments, combined Figures 1 to 4 As shown, the table body 1 is also provided with an operation panel 19, which is connected to the electric push rod 32. Passengers can control the operation of the electric push rod 32 through the operation panel 19, thereby controlling the extension or retraction of the projector 31, thereby increasing the convenience of operation. The operation panel 19 is provided with a power button and a lift button. The power button controls whether the projector 31 is powered on for projection, and the lift button controls the operating state of the electric push rod 32.

[0053] In some embodiments, as Figure 7 As shown, the projection assembly 3 also includes a rotating device 33, through which the projector 31 is connected to the telescopic mechanism; the rotating device 33 includes a first rotating member 331 and a second rotating member 332, the first rotating member 331 is connected to the telescopic mechanism, and the second rotating member 332 is connected to the projector 31, the first rotating member 331 and the second rotating member 332 are rotatably connected, and the rotation axis of the first rotating member 331 relative to the second rotating member 332 is parallel to the center line of the mounting slot. For example, the first rotating member 331 includes a first tube body, and the second rotating member 332 includes a second tube body, one end of the first tube body is connected to the telescopic mechanism, and one end of the second tube body is connected to the projector 31, the first tube body and the second tube body are sleeved together, and a bearing is provided at the connection position between the first tube body and the second tube body, so that the first tube body and the second tube body can rotate relative to each other, and the rotation axis is parallel to the center line of the mounting slot. For another example, the first rotating member 331 includes a first tube body, and the second rotating member 332 includes a rotating plate. One end of the first tube body is connected to the telescopic mechanism, and one side of the rotating plate is connected to the projector 31. The other end of the first tube body is provided with a universal ball, and the other side of the rotating plate is connected to the universal ball, so that the projector 31 can rotate around the center line of the mounting slot relative to the telescopic mechanism. In addition, the projector 31 can also rotate in other directions relative to the telescopic mechanism, thereby increasing the adjustment range of the projector 31.

[0054] In this design, the projector 31 can be rotated relative to the telescopic mechanism through the rotational cooperation between the first rotating member 331 and the second rotating member 332, which makes it easy for the operator to adjust the adjustment angle of the projector 31 to ensure the projection effect.

[0055] In some embodiments, as Figure 5 As shown, table 1 includes a support frame 11 and a tabletop 12. Tabletop 12 is disposed on the top of support frame 11. Projection board 2 is disposed on the top surface of tabletop 12, facing away from support frame 11. Projection board 2 can be directly connected to the top surface of tabletop 12 or connected via other structures, neither of which is restrictive. When unfolded, projection board 2 is perpendicular to the top surface. When folded, projection board 2 is parallel to the top surface.

[0056] In this design, the projection board 2 is placed on the top surface of the table top 12, so that the projection board 2 in the folded state can be used as a surface for the table body 1, which is convenient for working or placing items. When the projection board 2 is unfolded, it is perpendicular to the top surface, which facilitates imaging for the projector 31. After the projection board 2 is unfolded, the table top 12 can be used as a surface for placing items, making the table body 1 more compact and increasing the convenience of use.

[0057] In the related art, in order to ensure that passengers can enter the space, the distance between the desk and the seat is usually far, resulting in the passenger sitting on the seat feeling less comfortable due to the desk being too far away. In response to this, the present application also improves the desk board 12 of the desk, as follows:

[0058] In some embodiments, continue with reference to Figure 5 The office desk also includes a top plate 13, which is arranged between the top surface of the table plate 12 and the projection board 2. The top plate 13 is parallel to the top surface of the table plate 12, and the projection board 2 and the top plate 13 are foldably connected. The projector 31 is also arranged on the top plate 13 through the mounting groove. Specifically, the projector 31 is arranged on one side of the top of the top plate 13, and the flipped projection board 2 is located on the side of the top of the top plate 13 corresponding to the projector 31. Figure 3 and Figure 4 As shown, the top plate 13 is slidably connected to the table top 12, thereby driving the projector 31 and the projection board 2 to slide relative to the table top 12. When the top plate 13 is in the sliding state, the projector 31 can still be used, improving the user experience. The sliding direction of the top plate 13 is parallel to the top surface and perpendicular to the light output direction of the projector 31.

[0059] Under this design, in order to ensure that passengers can enter the space, the distance between the desk and the seat is designed to be far. When the passenger sits on the seat, the top plate 13 is moved toward the seat, thereby reducing the distance between the top plate 13 and the passenger, making it easier for the passenger to use and increasing the passenger comfort.

[0060] In some embodiments, combined Figure 1 and Figure 3As shown, a cover plate 18 is further provided on the top of the top plate 13, and a through hole 181 is provided at a position of the cover plate 18 corresponding to the projector 31. The top of the projector 31 stored in the mounting slot is in the same plane as the top of the cover plate 18, and the top of the projection board 2 folded on the top plate 13 is in the same plane as the top of the cover plate 18.

[0061] In this design, the projection plate 2 folded behind the top plate 13 and the cover plate 18 form a supporting plane, avoiding the top surface from being uneven and increasing the user experience.

[0062] In some embodiments, in order to facilitate passengers to operate the projection panel 2 , an escape opening 131 may be provided at the edge of the top panel 13 , and the passenger may open the projection panel 2 at the location of the escape opening 131 .

[0063] In some embodiments, a top cover is provided on the top of the projector 31, which is bonded to the top of the projector 31. The top cover has the same pattern and color as the cover plate 18, and both the top cover and the cover plate 18 of the projector 31 are made of fireproof board to ensure safety in use.

[0064] In some embodiments, combined Figure 5 、 Figure 6 and Figure 8 As shown, a sliding mechanism 14 is provided between the top plate 13 and the table top 12. The sliding mechanism 14 includes a scissor-type telescopic frame 141. One end of the scissor-type telescopic frame 141 is connected to the support frame 11, and the other end is hingedly connected to the top plate 13. Figure 8 As shown, the scissor-type telescopic frame 141 includes a connecting plate and a scissor arm. The scissor arm is connected to the support frame 11 via the connecting plate. The scissor arm includes multiple sets of cross rods, which are sequentially connected. Specifically, each set of cross rods includes two hingedly connected rod bodies, and the corresponding ends of the rod bodies of two adjacent sets of cross rods are hingedly connected. Among them, the hinge axis of the cross rod of the scissor-type telescopic frame 141 away from the connecting plate extends upward from the cross rod, and the extended end of the hinge axis is connected to a limit bracket. The scissor-type telescopic frame 141 is hingedly connected to the top plate 13 via the limit bracket.

[0065] Under this design, the scissor-type telescopic frame 141 can guide the movement of the top plate 13, and the scissor-type telescopic frame 141 has high strength and stability, can withstand large weight and pressure, and ensure the service life and stability of the movement of the top plate 13.

[0066] In other embodiments, a sliding mechanism 14 is provided between the top plate 13 and the table top 12 . The sliding structure includes a sliding track, which guides the movement of the top plate 13 .

[0067] It can be seen that the way the top plate 13 of the present application moves relative to the table top 12 is not restricted and can be designed according to actual needs.

[0068] In some embodiments, combined Figure 5 and Figure 9 As shown, a limiting mechanism 17 is provided between the top plate 13 and the table top 12. The limiting mechanism 17 includes limiting blocks 171 provided on the top plate 13 and the table top 12. When the top plate 13 moves to a preset maximum travel, the limiting blocks 171 on the top plate 13 contact the limiting blocks 171 on the table top 12, preventing the top plate 13 from excessively traveling and falling off. The design position of the limiting blocks 171 is not restricted and can be designed according to actual needs.

[0069] In some embodiments, combined Figure 2 、 Figure 4 and Figure 5 As shown, the desk also includes a support rod 15, one end of which is hingedly connected to the top plate 13, and the other end of which is connected to the projection board 2. The support rod 15 is used to maintain the projection board 2 in the deployed state. Specifically, when the projection board 2 is deployed to a vertical position, the support rod 15 can be rotated so that the end of the support rod 15 is supported on the projection board 2, thereby maintaining the position of the projection board 2. Alternatively, the end of the support rod 15 connected to the projection board 2 can slide with the projection board 2. When the projection board 2 is deployed, the end of the support rod 15 connected to the projection board 2 slides to a corresponding position, providing support for the projection board 2.

[0070] With this design, the support plate can maintain the position of the projection board 2 in the unfolded state, thereby achieving stable support for the projection board 2, avoiding the shaking of the projection board 2, and ensuring the projection effect and the viewing effect of the passengers.

[0071] In some embodiments, the support rod 15 is a telescopic rod hingedly connected to the projection panel 2. This type of support rod 15 can be extended after the projection panel 2 is unfolded and maintain the support position of the projection panel 2. When a force is applied to the projection panel 2, the support rod 15 can be retracted after the projection panel 2 is folded. For example, the support rod 15 can be a damped telescopic rod.

[0072] In this design, the support rod 15 can be extended as the projection board 2 is unfolded, and can be retracted as the projection board 2 is folded. There is no need for the passenger to adjust the position of the support rod 15, which increases the convenience of operation.

[0073] In some embodiments, to prevent the support rod 15 from affecting the user experience, one end of the support rod 15 hinged to the projection board 2 is located near the top board 13 of the projection board 2. Furthermore, there are two support rods 15, each hingedly connected to two corresponding sides of the projection board 2 to avoid occupying the projection area of the projection board 2.

[0074] In some embodiments, a receiving groove 16 is provided on the top plate 13 , and when the projection panel 2 is in the folded state, the support rod 15 is received in the receiving groove 16 .

[0075] This design facilitates the storage of the support rod 15 in the folded state, so that the top surface of the projection board 2 can be parallel to the top surface of the top board 13 after being folded, so that it can function as a board surface.

[0076] In other embodiments, the office desk also includes a rotating drive component, which includes a driving motor arranged on the table body 1 and a driving gear arranged on the output shaft of the driving motor. The hinged end of the projection board 2 and the top plate 13 is provided with a hinge shaft, and the hinge shaft is provided with a driven gear engaged with the driving gear. The driving motor can drive the projection board 2 to rotate through the cooperation of the driving gear and the driven gear to achieve automatic rotation.

[0077] It can be seen that the opening method of the projection board 2 of the present application is not limited and can be designed according to actual needs.

[0078] The working process of the desk provided by this application is as follows:

[0079] To use projector 31, manually lift projection panel 2 until it rotates to a vertical position. Support rod 15 then extends as projection panel 2 unfolds, supporting it. The lift button controls electric push rod 32 to raise projector 31. Pressing the power button powers projector 31 on, projecting an image toward projection panel 2. The projection angle can be adjusted by rotating projector 31, ensuring the projection effect meets viewing needs and providing convenient operation. After use, power is turned off, and electric push rod 32 lowers projector 31 back into its mounting slot.

[0080] In the description of the embodiments of the present application, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0081] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
