[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 14 The invention describes a vehicle-mounted folding screen according to an embodiment of the invention.

[0038] At present, most vehicles install display screens on the backrests of the front seats to meet the viewing needs of rear passengers. However, this kind of display screen will take up the back row space after the screen is turned on, and adjusting the sitting posture of the front row will affect the use of the back row, which lacks convenience.

[0039] To this end, the utility model proposes a vehicle-mounted folding screen installed on the roof of a vehicle.

[0040] like Figure 1-Figure 6 As shown, the vehicle-mounted folding screen includes: a display screen 1 and a rotating component 2.

[0041] An inner gear ring 11 is provided on the top of the display screen 1, and the rotating component 2 is arranged on the roof of the vehicle. The rotating component 2 includes a rotating wheel 21. The rotating wheel 21 is meshed with the inner gear ring 11, and the driving force drives the rotating wheel 21 to rotate around its own center. The inner gear ring 11 rotates around the rotating wheel 21 to drive the display screen 1 to flip to an open or folded state.

[0042] It should be noted that the arrangement of the rotating component 2 on the vehicle roof refers to the arrangement position of the rotating component 2 on the vehicle body interior, so that the display screen 1 is installed on the vehicle roof to meet the viewing and gaming needs of the rear passengers.

[0043] In the feasible technical solution, the rotating assembly 2 can be fixedly mounted on the vehicle roof, or arranged on the vehicle roof by connecting with other components. Therefore, the relationship between the rotating assembly 2 and the vehicle roof described above is a spatial arrangement relationship, not a fixed connection relationship.

[0044] Specifically, the rotating wheel 21 in the rotating assembly 2 is meshed with the inner gear ring 11 at the top of the display screen 1. When the driving force drives the rotating wheel 21 to rotate around its own center, the inner gear ring 11 rotates around the rotating wheel 21, thereby driving the display screen 1 to flip around its top as the rotation axis, so that the display screen 1 is flipped to an open state or a folded state.

[0045] In addition, the vehicle-mounted folding screen also includes a driving assembly 5 that provides driving force, which includes a driving member 51 and an output shaft 53 connected to the driving member 51, and the output shaft 53 is connected to the rotating assembly 2. The driving member 51 controls the output shaft 53 to rotate to transmit the driving force to the rotating assembly 2. The driving member 51 can be a stepping motor in the prior art. The driving member 51 is provided with program instructions to control the output shaft 53 to stop after rotating to any angle, thereby controlling the display screen 1 to flip to any angle to meet the use needs of rear passengers.

[0046] Therefore, by placing the display screen 1 on the roof of the vehicle and being able to open and fold it as needed, the needs of rear passengers for watching movies and playing games are met without affecting the riding space of rear passengers, greatly improving the entertainment and intelligence of the car. In addition, it is conducive to increasing the specifications of the display screen 1, thereby improving the comfort and interactivity of the display screen 1. At the same time, the display screen 1 can be opened or folded by flipping, which makes it easier to store and use the display screen 1.

[0047] Furthermore, the diameter of the rotating wheel 21 is smaller than the diameter of the inner gear ring 11 .

[0048] refer to Figure 5 and Figure 6 As shown, the rotating wheel 21 with a large diameter drives the inner gear ring 11 with a small diameter to rotate, so that the rotating wheel 21 rotates faster than the inner gear ring 11, thereby achieving a deceleration effect so that the display screen 1 can be slowly opened or folded.

[0049] Furthermore, the vehicle-mounted folding screen also includes: two brackets 3 arranged opposite to each other on the roof of the vehicle, the display screen 1 is arranged between the two brackets 3, and the rotating assembly 2 is arranged on each side bracket 3.

[0050] Among them, each side rotating assembly 2 includes a driving wheel 22 coaxially connected to the rotating wheel 21, and the driving wheel 22 is arranged to roll on the bracket 3. When the rotating wheel 21 and the driving wheel 22 rotate synchronously, the driving wheel 22 rolls on the bracket 3 to drive the display screen 1 to move in the front and rear directions of the vehicle and synchronously flip to an open or folded state.

[0051] Specifically, two opposite brackets 3 are arranged on the vehicle roof, wherein the brackets 3 can be fixed on the vehicle roof by welding or screws. A rotating assembly 2 is provided on each side bracket 3 .

[0052] refer to Figure 4-Figure 8 As shown, the driving wheel 22 of the rotating component 2 is coaxially connected with the rotating wheel 21, the driving wheel 22 is arranged to roll on the bracket 3, and the rotating wheel 21 is kept in meshing with the inner gear ring 11. When the driving force drives the driving wheel 22 and the rotating wheel 21 to rotate synchronously, the driving wheel 22 can roll on the bracket 3, and the inner gear ring 11 can rotate around the rotating wheel 21, so that the display screen 1 can flip around its top and move in a straight line along the rolling direction of the driving wheel 22.

[0053] The bracket 3 is extended along the front-rear direction of the vehicle, and a rack 31 is provided on the bracket 3, so that the driving wheel 22 can roll along the rack 31 on the bracket 3, that is, the rolling direction is the front-rear direction of the vehicle.

[0054] Therefore, by rolling the driving wheel 22 and the rack 31 on the bracket 3, and meshing the rotating wheel 21 with the inner gear ring 11 of the display screen 1, the display screen 1 can be flipped to the open state or the folded state while moving along the front and rear direction of the vehicle, thereby improving the comfort of the display screen 1 and greatly meeting the use needs of passengers. Moreover, the movement form of the vehicle-mounted folding screen of the present application is relatively simple, the structure is stable, and it is easy to install and implement.

[0055] Furthermore, the diameter of the driving wheel 22 is greater than the diameter of the rotating wheel 21 .

[0056] refer to Figure 4 As shown, the rotation speed of the driving wheel 22 is greater than the rotation speed of the rotating wheel 21, so that the driving wheel 22 can quickly slide on the bracket 3 to the open position or the folded position, and the rotating wheel 21 is engaged with the inner gear ring 11, and the inner gear ring 11 needs to rotate relatively slowly around the rotating wheel 21 to achieve the display screen 1 slowly flipping to the open position or the folded position.

[0057] Furthermore, the rotating assembly 2 includes a rotating shaft 23, one end of which is provided with a driving wheel 22 and a rotating wheel 21, a shaft wheel 41 axially connected to the rotating shaft 23 is provided between the driving wheel 22 and the rotating wheel 21, the shaft wheel 41 is provided with a slider 42, and the slider 42 is provided with a first sliding portion 43, and the bracket 3 is provided with a second sliding portion 32, and when the driving wheel 22 rolls on the bracket 3, the first sliding portion 43 slides on the second sliding portion 32.

[0058] refer to Figure 4 , Figure 8-Figure 12 As shown, one end of the rotating shaft 23 is provided with a driving wheel 22 and a rotating wheel 21 , and the other end of the rotating shaft 23 can be connected to the driving component 5 to transmit the driving force output by the driving component 5 to the driving wheel 22 and the rotating wheel 21 .

[0059] Among them, an axle wheel 41 axially connected to the rotating shaft 23 is provided between the driving wheel 22 and the rotating wheel 21. Specifically, a slider 42 is provided on the side of the axle wheel 41 close to the driving wheel 22, and a first slider 42 portion such as a slide groove is provided at the bottom of the slider 42. Correspondingly, a second sliding portion 32 such as a slide rail is provided on the bracket 3. When the driving force is transmitted to the rotating shaft 23, the rotating wheel 21 meshes with the inner gear ring 11 for transmission, the driving wheel 22 rolls with its rack 31 on the bracket 3, and the slider 42 on the outer side of the axle wheel 41 slides with the bracket 3.

[0060] like Fig.10 As shown, the shaft wheel 41 is provided with a shaft wheel shaft hole 44, so that the rotating shaft 23 passes through the shaft wheel shaft hole 44 and is axially connected with the shaft wheel 41. The slider 42 may be provided with a hole structure corresponding to the shaft wheel shaft hole 44 to be axially connected with the rotating shaft 23.

[0061] Therefore, by setting the shaft wheel 41 so that its slider 42 slides with the bracket 3, it can be ensured that the driving wheel 22 and the rotating wheel 21 of the rotating component 2 will not be offset, and the display screen 1 can be ensured to move linearly in the front and rear directions of the vehicle, and the display screen 1 is limited in the up and down directions and left and right directions of the vehicle, thereby improving the linear motion accuracy of the display screen 1.

[0062] Furthermore, the top of the display screen 1 is provided with an axial hole 12 that passes through both ends, and an internal gear ring 11 is provided at each end of the axial hole 12. The rotating shaft 23 and the rotating wheel 21 are arranged in the axial hole 12, and the wheel axle is axially connected to the two ends of the axial hole 12. The driving wheel 22 and the slider 42 cooperate with the bracket 3.

[0063] refer to Figure 2 , Figure 6 , Figure 8 , Fig.10 and Fig.11 As shown, the top of the display screen 1 is provided with an axial hole 12 that passes through both ends thereof, and the axial hole 12 serves as an installation space, so that the rotating component 2 can be installed in the axial hole 12. Among them, the rotating shaft 23 and the rotating wheel 21 of the rotating component 2 are arranged in the axial hole 12, so that the rotating wheel 21 meshes with the inner gear ring 11 at the end of the axial hole 12. And, the driving wheel 22 of the rotating component 2 extends out of the axial hole 12, so that the driving wheel 22 rolls with the bracket 3 on the roof of the vehicle. In addition, the wheel axle is axially connected with the end of the axial hole 12, and the slider 42 on the outer side of the wheel axle is arranged outside the axial hole 12, so that the slider 42 slides with the bracket 3.

[0064] Since the axle is arranged on the inner side of the driving wheel 22 , the second sliding part 32 on the bracket 3 is arranged on the inner side of the rack 31 , so that the slider 42 on the axle cooperates with the second sliding part 32 of the bracket 3 , and the driving wheel 22 cooperates with the rack 31 of the bracket 3 .

[0065] Furthermore, the vehicle-mounted folding screen also includes: an axle frame 4, which is arranged in the axle hole 12, and both ends of the axle frame 4 are connected to the axle wheels 41 on the rotating shafts 23 on each side.

[0066] refer to Fig. 9 As shown, the shaft frame 4 is installed in the shaft hole 12, and the two ends of the shaft frame 4 are connected to the shaft wheels 41 located on the rotating shaft 23 of the rotating shaft assembly on each side, so that the shaft frame 4 and the shaft wheel 41 form an integral structure, which can ensure that the rotating assembly 2 on each side moves linearly on the bracket 3 synchronously, thereby improving the movement accuracy of the display screen 1.

[0067] Furthermore, the vehicle-mounted folding screen also includes: a driving component 5, which is arranged in the shaft hole 12, and both ends of the output shaft 53 of the driving component 5 are respectively connected to one end of each side rotating shaft 23 away from the rotating wheel 21.

[0068] refer to Fig. 9 and Fig.12 As shown, the driving assembly 5 is installed in the shaft hole 12, and the two ends of its output shaft 53 are respectively connected to the ends of the rotating shaft 23 of the rotating assembly 2 on each side away from the driving wheel 22. The driving assembly 5 is further fixed on the shaft frame 4, so that the rotating assembly 2, the driving assembly 5 and the shaft frame 4 form a large driving mechanism, so that the large driving mechanism is conveniently hidden in the shaft hole 12 of the display screen 1, which is not only convenient for installation, but also improves the aesthetics of the ceiling.

[0069] Furthermore, the driving assembly 5 includes: a driving member 51 and a reduction mechanism 52, the output end of the driving member 51 is transmission-connected to the reduction mechanism 52, both ends of the output shaft 53 of the reduction mechanism 52 are connected to the rotating assemblies 2 on each side, and the reduction mechanism 52 includes at least a two-stage worm gear mechanism.

[0070] refer to Fig.13 and Fig.14 As shown, the output end of the driving member 51 is in transmission connection with the reduction mechanism 52. Specifically, the output end of the driving member 51, such as a stepping motor, is a worm, which meshes with a primary worm wheel 54, which meshes with a primary worm, which meshes with a secondary worm wheel 55, and the secondary worm wheel 55 extends an output shaft 53 to the left and right to be connected with the rotating shaft 23 of the rotating assembly 2 on each side.

[0071] A coupling 24 is provided at one end of the rotating shaft 23 to be connected to the output shaft 53 of the driving assembly 5 .

[0072] Furthermore, the display screen 1 includes a connecting shaft 13 and a screen 14 which are connected to each other. The connecting shaft 13 is provided with an inner gear ring 11 . The connecting shaft 13 rotates to drive the screen 14 to flip.

In addition, the rotating assembly 2, the shaft frame 4 and the driving assembly 5 are all installed in the shaft hole 12, and the vehicle-mounted folding screen has only the bracket 3 arranged on the vehicle roof and exposed on the vehicle roof with the display screen 1.

[0074] Combination Figure 3 As shown, when the display screen 1 needs to be opened, the driving assembly 5 on the shaft frame 4 is activated and drives the rotating shaft 23 to rotate. Under the meshing action of the driving wheel 22 and the rack 31, the driving wheel 22 of the rotating shaft 23 will roll forward along the rack 31 of the bracket 3. Under the action of the shaft connection, the rotating shaft 23 drives the shaft frame 4 to slide forward along the second sliding portion 32 of the bracket 3 such as a slide rail. Under the action of the shaft connection and meshing, the shaft frame 4 drives the display screen 1 to slide forward while the inner gear ring 11 of the display screen 1 rotates downward around the rotating wheel 21 of the rotating shaft 23.
