[0043] 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. Those skilled in the art should know that the embodiments described below are part of the embodiments disclosed in the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The following describes various non-limiting embodiments of the present invention in detail. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0045] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0046] See also Figure 1-18 The present invention will be described in detail below with reference to the accompanying drawings and embodiments:

[0047] The multifunctional vehicle-mounted screen described in the present invention includes a bottom frame 1 and a side frame 2 vertically arranged on the upper end surface of the bottom frame 1, the side frame 2 includes a front frame 2-1, a rear frame 2-2 and a right side frame 2-3, and a top plate 4 is provided at the upper end of the side frame 2. The lower end surface of the top plate 4 is fixed to the upper end surface of the front frame 2-1 and the rear frame 2-2 respectively, and the right end surface of the top plate 4 is hinged to the upper end surface of the right side frame 2-3. The bottom frame 1, the side frame 2 and the top plate 4 form a car compartment space.

[0048] In the present utility model, display screen mounting frames 3 are provided on the outer sides of the front frame 2-1 and the rear frame 2-2, and the right ends of the display screen mounting frames 3 on both sides are hinged to the right frame 2-3; the outer sides of the display screen mounting frames 3 and the right frame 2-3 are provided with vehicle-mounted screens 5; the inner sides of the adjacent ends of the vehicle-mounted screen 5 on the display screen mounting frame 3 and the vehicle-mounted screen 5 on the right frame 2-3 are adapted as matching inclined surfaces, such as inclined surfaces of 45°, for realizing seamless splicing of the display screen mounting frame 3 and the vehicle-mounted screen 5 on the right frame 2-3; the axes of the hinge shafts of the display screen mounting frames 3 on both sides and the right frame 2-3 respectively coincide with the intersection lines of the seamless splicing of the adjacent ends of the corresponding side display screen mounting frames 3 and the vehicle-mounted screen 5 on the right frame 2-3; the vehicle-mounted screen 5 is spliced by a number of LED panels 6.

[0049] When in use, the vehicle-mounted screen 5 on the side frame 2 plays images and / or videos for display. Since the adjacent ends of the vehicle-mounted screen 5 set on the display mounting frame 3 and the vehicle-mounted screen 5 set on the right frame 2-3 are seamlessly spliced, the played video can have a 3D effect when viewed at a designated position.

[0050] In the present invention, the display screen mounting frames 3 on both sides are hinged to the right side frame 2-3 through a rotating device. The rotating device includes a first connecting rod 8 and a second connecting rod 9 hinged through a rotating shaft 10. The fixed end of the first connecting rod 8 is fixedly connected to the right upper end of the display screen mounting frame 3, and the fixed end of the second connecting rod 9 is fixedly connected to the right upper end of the top plate 4.

[0051] During the rotation process, since the axis of the rotating shaft 10 coincides with the intersection line, the relative movement between the display screen mounting frame 3 and the right side frame 2-3 can be made more stable and smooth, avoiding vibration and noise caused by unstable movement, thereby improving the stability and reliability of the vehicle-mounted screen 5; it can also ensure that the seamlessly spliced display screen mounting frame 3 and the vehicle-mounted screen 5 on the right side frame 2-3 can rotate smoothly.

[0052] In the present utility model, the first connecting rod 8 includes a sealing plate 7 fixedly arranged on the upper end surface of the display screen mounting frame 3 and a connecting rod 11 fixedly arranged on the upper end surface of the sealing plate 7, and the free end of the connecting rod 11 is fixedly arranged on the rotating shaft 10; the right end of the top plate 4 is provided with an avoidance notch 42 adapted to the sealing plate 7.

[0053] In this embodiment, when the display screen mounting frame 3 is rotated to be parallel to the length direction of the top plate 4, the sealing plate 7 is located in the avoidance gap 42, so that the sealing plate 7 seals the avoidance gap 42, ensuring that a sealed space is formed in the compartment space when the display screen mounting frames 3 on both sides are not unfolded; the vehicle-mounted screen 5 on the display screen mounting frame 3 can be unfolded as needed to form a large display screen for display, that is, by rotating the front display screen mounting frame 3 and the rear display screen mounting frame 3 until the vehicle-mounted screen 5 on the front display screen mounting frame 3 and the rear display screen mounting frame 3 and the vehicle-mounted screen 5 on the right side frame 2-3 form a flat large display screen, and the length of the large display screen is the sum of the lengths of the front display screen mounting frame 3, the rear display screen mounting frame 3 and the vehicle-mounted screen 5 on the right side frame 2-3.

[0054] In the present invention, a support portion 12 is provided at the bottom of the left end of the front display screen mounting frame 3 and the rear display screen mounting frame 3. The support portion 12 is used to support the front display screen mounting frame 3 and the rear display screen mounting frame 3 after the front display screen mounting frame 3 and the rear display screen mounting frame 3 are rotated to be in the same plane as the right side frame 2-3.

[0055] In this embodiment, the support portion 12 includes an outer rod 13 hingedly connected to the display mounting frame 3 and legs 14 slidably disposed within the outer rod 13. Locking bolts 16 are threadedly connected to the outer rod 13. External rod stoppers, such as removable stop pins, may also be provided on the inner surface of the display mounting frame 3 on either side of the outer rod 13. These stoppers, when supported by the support portion 12, prevent the outer rod 13 from rotating due to accidental contact, thereby ensuring stable support. Stop pins are conventional in the art and will not be described in detail here.

[0056] When the front and rear display screen mounting frames 3 have been fully unfolded and need support, the outer rod 13 of the support portion 12 is rotated to be perpendicular to the ground, and the height of the legs 14 can be adjusted by rotating the locking bolts 16 to stably support the front and rear display screen mounting frames 3, maintaining the front and rear display screen mounting frames 3 and the right side frame 2-3 in the same plane. The height-adjustable legs 14 can better adapt to different ground heights; when the front and rear display screen mounting frames 3 need to be rotated and retracted, the legs 14 are retracted upward by rotating the locking bolts 16, and then the outer rod 13 is rotated to return the rotating outer rod 13 to a horizontal position, and then the front and rear display screen mounting frames 3 and the rear display screen mounting frames 3 are rotated to the inside of the side frame 2.

[0057] In the present invention, the front frame 2-1, the rear frame 2-2 and the right frame 2-3 all include a plurality of vertical rods 17 fixedly arranged vertically with the bottom frame 1, and the top ends of the vertical rods 17 are fixedly arranged with the top plate 4. A connecting block 18 is fixedly connected to the vertical rod 17 on the left side, and a fixing bolt 19 is threadedly connected to the connecting block 18. A threaded hole 20 is provided on the inner side surface of the left end of the display screen mounting frame 3 at a position corresponding to the fixing bolt 19.

[0058] In order to ensure the stability of the connection between the front display screen mounting frame 3 and the rear display screen mounting frame 3 and the side frame 2, and to avoid shaking during the movement of the vehicle-mounted screen 5, the display screen mounting frame 3 can be locked on the frame through the connecting block 18 fixedly connected to the left vertical rod 17 and the fixing bolt 19 threaded on the connecting block 18 to prevent it from moving accidentally.

[0059] In the present invention, the top end of the right side frame 2 - 3 is hinged to the right end of the top plate 4 .

[0060] In this embodiment, the upper right side surface of the right vertical rod 17 is hinged with a hydraulic telescopic rod 43, and the movable end of the hydraulic telescopic rod 43 is hinged to the right frame body 2-3.

[0061] In the present invention, a plurality of fixing hoops 22 are fixedly provided at the bottom end of the right side frame 2-3, a pin shaft 23 is passed through each fixing hoop 22, and a clamping block 24 is fixedly provided at both ends of the pin shaft 23. Fixed blocks 25 are fixedly provided on the front and rear sides of the bottom right end of the bottom frame 1, and limiting holes 26 that are compatible with the clamping blocks 24 are opened on the fixing block 25. The clamping blocks 24 at both ends of the pin shaft 23 are inserted into the corresponding limiting holes 26.

[0062] When in use, when the right side frame 2-3 needs to be opened, the pin shaft 23 is axially moved so that the blocks 24 fixed at both ends thereof are horizontally disengaged from the limiting holes 26 on the fixing blocks 25 provided on the bottom frame 1. At this time, the right side frame 2-3 can be flipped upward to facilitate the entry of the staff; when the right side frame 2-3 needs to be closed, the right side frame 2-3 is first rotated so that the right side frame 2-3 contacts the front side frame 2-1 and the rear side frame 2-2, and then the pin shaft 23 is axially moved so that the two blocks 34 of the pin shaft 23 are horizontally inserted into the corresponding limiting holes 36, thereby realizing the connection between the right side frame 2-3 and the bottom frame 1 and preventing the right side frame 2-3 from opening.

[0063] In this embodiment, when it is necessary to rotate the front display screen mounting frame 3 and the rear display screen mounting frame 3 to be in the same plane with the right side frame 2-3, the staff needs to first open the right side frame 2-3 to enter the interior of the car, unscrew the fixing bolts 19 fixed on the connecting block 18, unlock the front display screen mounting frame 3 and the rear display screen mounting frame 3, and now the front display screen mounting frame 3 and the rear display screen mounting frame 3 can be rotated to be in the same plane with the right side frame 2-3.
