[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please also read Figures 1 to 9 The installation structure of the ceiling screen provided by the utility model is now described. The installation structure of the ceiling screen includes: a ceiling base and a display screen 11. The ceiling base is provided with a fixing structure and a pre-installation structure that can be installed on the roof sheet metal; the display screen 11 is installed on the ceiling base through a flip driving mechanism 7 and a flip supporting mechanism 8.

[0030] The installation structure of the ceiling screen provided by the utility model is that the display screen 11 is rotatably connected with the ceiling base, and a fixing structure and a pre-installation structure are arranged on the ceiling base. During installation, the ceiling base is first hung on the roof sheet metal through the pre-installation structure, and then the hand can be released to fix the ceiling screen on the roof sheet metal. In this installation method, the ceiling screen is first hung on the roof sheet metal through the pre-installation structure with both hands or one hand. After the hand is released, the ceiling screen will not fall off. At this time, the tool and the connecting piece are taken to fix the ceiling screen. The fixing can be completed by one person, and there is no need to hold the ceiling screen with one hand and install it with the other hand, or one person holds the ceiling screen and the other person fixes it. The installation is simple and convenient, saving time and effort.

[0031] It is noted that, with the installation structure provided in this embodiment, it is only necessary to drill corresponding threaded holes on the roof sheet metal in advance. This method of directly fixing the ceiling screen on the roof sheet metal does not require an additional mounting bracket for the ceiling screen on the roof sheet metal. The ceiling screen can be installed on the roof sheet metal only through the fixing structure, and the installation structure is also very simple. Preferably, a sheet metal structure protruding downward is provided on the roof sheet metal, which cooperates with the support boss 101 on the mounting base 1 to improve the installation strength; when a bolt connection is adopted, the length of the threaded hole can be increased through the protruding sheet metal structure, and the length of the bolt and the roof sheet metal can be increased, thereby improving the firmness of the connection.

[0032] Among them, the ceiling screen can be installed in the middle position above the front of the second row of seats, without exceeding the front seats, so that the back passengers can watch it without affecting the front passengers; the ceiling screen can also be installed on the roof sheet metal above the front of the front passenger seat for the passenger in the front passenger seat to watch, and it will not bump into the passenger in the front passenger seat at the top of the roof; other installation positions can be personalized according to the number and arrangement of vehicle seats, as well as personal preferences, without any restrictions.

[0033] In some embodiments, see Figure 1 , Figure 3 and Figure 4 As shown, the fixing structure includes a plurality of support bosses 101 distributed along the periphery of the display screen 11, and the support bosses 101 are provided with mounting holes through which the first bolts 3 can pass, and the ceiling base is fixed to the roof sheet metal by the first bolts 3. In this embodiment, on the ceiling base, two support bosses 101 are dispersedly provided on the side where the display screen 11 is opened, and three support bosses 101 are dispersedly provided on the side opposite to the open display screen 11, and the ceiling base can be fixed to the roof sheet metal by five first bolts 3. The top surface of the support bosses 101 can form contact with the roof sheet metal, and space is reserved for the controller 4 and the wiring harness provided on the ceiling base, that is, the controller 4 and the wiring harness are prevented from directly contacting the roof sheet metal, and a gap is formed between the ceiling base and the roof sheet metal through the support of the support bosses 101, which is also conducive to the dispersion and propagation of heat from the display screen 11 and electrical components, and prevents the display screen 11 and electrical components from overheating and affecting the performance.

[0034] The number and design positions of the supporting bosses 101 can be adjusted, specifically to ensure that the ceiling screen can be stably and reliably fixed on the roof sheet metal while avoiding waste of resources caused by excessive arrangement.

[0035] Optionally, reinforcing ribs are arranged around the supporting boss 101 to enhance the supporting strength of the supporting boss 101 .

[0036] In some embodiments, see Figure 1 and Figure 3 As shown, the pre-installation structure includes a pre-tightening buckle 102 arranged on the top surface of the ceiling base, and the ceiling base is pre-tightened on the roof sheet metal with the help of the pre-tightening buckle 102. Through the pre-tightening buckle 102, the ceiling base can be pre-tightened on the roof sheet metal first, and it will not fall off after letting go, so that the hand can be freed to facilitate the screwdriver to pass the bolt through the mounting hole and tighten it with the roof sheet metal. At the same time, the pre-tightening buckle 102 also has the function of pre-positioning. When the pre-tightening buckle 102 is clamped on the roof sheet metal, the mounting hole on the ceiling base will also be aligned with the threaded hole on the roof sheet metal, which is convenient for the installation of the bolt.

[0037] Among them, it is appropriate to set the pre-tightening buckle 102 at the center position of the installation base plate, that is, the pre-tightening buckle 102 is at the center position of the display screen or the center of gravity. In this way, when the pre-tightening buckle 102 is pre-connected with the roof sheet metal, the ceiling screen can maintain a horizontally balanced state, and there will be no situation where one side tilts downward, which will cause the pre-installed ceiling screen to be unstable and have the risk of falling.

[0038] Preferably, two pre-tightening buckles 102 are dispersedly arranged on the ceiling base, and are arranged on the center line connecting the two wide sides of the ceiling base, and are symmetrically arranged on both sides of the center line connecting the two long sides of the ceiling base. When the ceiling base is pre-installed on the roof sheet metal through the two pre-tightening buckles 102, it can ensure that the center of the ceiling base is between the two pre-tightening buckles 102, ensure that the two pre-tightening buckles 102 are evenly stressed, improve the balance and stability of the ceiling screen after pre-installation, thereby avoiding the hidden danger of the ceiling screen tilting and the risk of falling.

[0039] After the ceiling screen is hung on the roof sheet metal through this pre-installation, you can release your hands and tighten the ceiling screen, which saves time and effort in the installation of the ceiling screen and improves the convenience of the installation of the ceiling screen.

[0040] In some embodiments, see Figure 1 and Figure 3 As shown, a positioning structure is also provided on the ceiling base, and the positioning structure can cooperate with the positioning hole on the roof sheet metal. Specifically, the positioning structure includes at least one first positioning pin 103, and this embodiment adopts two positioning pins dispersedly arranged near the two pre-tightening buckles 102 for positioning.

[0041] When installing the ceiling screen, the positioning pin preferentially contacts the first positioning hole on the roof sheet metal to position the ceiling screen for installation, and then the ceiling screen is pre-fixed on the roof by the pre-tightening buckle 102, and finally the ceiling screen is firmly fixed by bolts. Such installation is simple and convenient, saving time and effort.

[0042] The ceiling screen of this embodiment is installed as a whole, and the display screen 11 is connected to the ceiling base through a flip drive mechanism 7. The ceiling base includes a mounting base 1 that can be directly fixed to the roof sheet metal, a base trim 6 fixed to the lower surface of the mounting base 1, and a decorative cover 2 arranged on the lower surface of the mounting base 1; the flip drive mechanism 7 and the flip support mechanism 8 are installed on the mounting base 1, and the base trim 6 is located in the area where the display screen 11 is fitted after being closed; the decorative cover 2 is arranged around the base trim 6. In this embodiment, the mounting base plate 1 is used as a load-bearing component to provide support for the flip drive mechanism 7, the flip support mechanism 8 and the display screen 11. The base plate trim 6 is fixed on the mounting base plate 1 in an area corresponding to the display screen 11 when it is closed. On the one hand, it protects the surface of the display screen 11 after it is closed. In particular, when the display screen 11 is flipped open, the base plate trim 6 serves as a decorative function on the top to provide customers with a refined sense of space. However, since the bolts that penetrate the mounting base plate 1 are fastened to the roof sheet metal, and the flip drive mechanism 7 and the flip support mechanism 8 are also exposed on the lower surface of the mounting base plate 1, affecting the appearance quality, the decorative cover 2 is arranged around the display screen 11 to hide the installation traces and the unnecessary exposed flip drive mechanism 7, the flip support mechanism 8 and the locking mechanism 9 in the decorative cover 2, thereby also enhancing the refined feeling of the riding space.

[0043] This kind of ceiling screen is installed as a whole, and the display screen 11, base trim 6 and decorative cover 2 are all installed with the mounting base 1 when leaving the factory. When the ceiling screen needs to be installed on the roof sheet metal, first remove the decorative cover 2, fix the base plate on the roof sheet metal, and then install the decorative cover 2, and it can be easily done.

[0044] Therefore, the support boss 101 is arranged on the mounting base plate 1 and is located on the periphery of the base plate trim 6. It will not interfere with the base plate trim 6 and the display screen 11 and will not affect the installation of the mounting base plate 1. After the mounting base plate 1 is fastened to the roof sheet metal by the first bolt 3, the decorative cover 2 is installed to cover the bolts and prevent them from being exposed.

[0045] In this embodiment, the installation base plate 1 can be made of metal parts to ensure structural strength; the base plate trim 6 and the decorative cover 2 can both be made of plastic products, which can enhance the exquisiteness of the interior of the car and liven up the atmosphere inside the car through changes in appearance and color.

[0046] In some embodiments, see Figure 1 , Figures 3 to 5As shown, a plurality of support columns 61 are dispersedly arranged on the upper surface of the bottom plate trim 6, and the support columns 61 are provided with internal threads. The second bolts 5 that penetrate the mounting bottom plate 1 are screwed on the support columns 61 from top to bottom, so that the bottom plate trim 6 is connected to the mounting bottom plate 1. In this embodiment, the bottom plate trim 6 and the mounting bottom plate 1 are fastened by the second bolts 5, and this fixation is firm and reliable; because the outer surface of the bottom plate trim 6 is a decorative surface, it is not convenient to set a through hole, therefore, the support columns 61 are constructed on the upper surface of the bottom plate facing the mounting bottom plate 1, and the internal threads are provided, so that the bottom plate trim 6 and the mounting bottom plate 1 are fastened together by the bolts.

[0047] In order to improve the structural rigidity of the bottom panel trim 6 and the structural strength of the installation bottom panel 1, vertical and horizontal cross-reinforcement ribs may be provided on the bottom panel trim 6 to ensure the support strength of each position of the bottom panel trim 6. Similarly, vertical and horizontal cross-reinforcement ribs are provided on the installation bottom panel 1 to improve the support strength and anti-deformation performance of the installation bottom panel 1.

[0048] Optionally, the base plate trim 6 can be snap-connected to the mounting base plate 1 by means of buckles, and this type of installation is also simple and convenient.

[0049] Among them, Figure 5 As shown, the bottom plate trim 6 is also provided with a positioning structure for easy assembly, which is named as the second positioning pin 62 here to distinguish it from the previous positioning structure; in this embodiment, the bottom plate trim 6 is not only provided with support columns 61 scattered along its four sides, but also provided with a support column 61 in the central area of ​​the bottom plate trim 6 to ensure the balance of support and fixation of each position of the bottom plate trim 6 and avoid deformation of the bottom plate trim 6; the second positioning pin 62 is designed with the support column 61, wherein the two opposite support columns 61 are provided with the second positioning pin 62; of course, the installation bottom plate 1 is provided with through holes and positioning holes corresponding to the support columns 61 and the second positioning pin 62, which are defined as the second positioning holes. Similarly, in order to improve the supporting strength of each support column 61, corresponding reinforcing ribs are provided.

[0050] In this article, reinforcing ribs are provided on the installation base plate 1, the base plate trim 6, the decorative cover 2, the supporting boss 101, the supporting column 61 and other places, all of which play a reinforcing role, so they are no longer marked one by one in the figure.

[0051] In some embodiments, see Figure 1 , Figure 3 and Figure 6 As shown, the decorative cover 2 is clamped on the mounting base plate 1 through a clamping structure, and the clamping structure includes clamping claws 21 dispersedly arranged around the upper surface of the decorative cover 2, and the mounting base plate 1 is correspondingly provided with clamping holes 104 that are clamped with the clamping claws 21. Since the appearance of the decorative cover 2 cannot have any traces, the decorative cover 2 can be directly clamped on the mounting base plate 1, and the installation is simple and convenient.

[0052] Similarly, if Figure 6 As shown, the decorative cover 2 is also provided with a positioning pin, named as the third positioning pin 22 , and the mounting base plate 1 is correspondingly provided with a third positioning hole.

[0053] Alternatively, see Figure 2 A space perception sensor 10 is integrated on the decorative cover 2 and fixed on the mounting base plate 1 by snapping. It can not only decorate the motion structure on both sides of the display screen 11, but also save the layout space of the space perception sensor 10. At the same time, the space perception sensor 10 can be used to receive gesture signals. After the gesture signals are transmitted to the flip drive motor 71, the flipping movement of the display screen 11 is realized.

[0054] In some embodiments, Figure 4 , Figures 7 to 9 As shown, it also includes a locking mechanism 9 for locking the display screen 11, and the locking mechanism 9 is arranged on the lower surface of the ceiling base. The locking mechanisms 9 are arranged on opposite sides of the display screen 11. When the display screen 11 is closed and attached to the bottom plate trim 6, the locking mechanism 9 can lock the display screen 11 to prevent the display screen 11 from flipping over when it is closed.

[0055] In some embodiments, Figure 8 As shown, the locking mechanism 9 includes a locking drive motor 91, a gear transmission assembly and a lock tongue 93. The locking drive motor 91 drives the gear transmission assembly to rotate. The locking drive motor 91, the gear transmission assembly and the lock tongue 93 are all arranged in a locking housing 94. The lock tongue 93 is provided with a tooth shape meshing with the gear transmission assembly. The locking drive motor 91 drives the lock tongue 93 to extend or retract through the lock tongue 93 gear transmission assembly. In this embodiment, the lock tongue 93 is equivalent to a rack. The lock tongue 93 is driven to extend or retract linearly by a gear transmission method. The self-locking function of the gear and the rack is utilized. When the lock tongue 93 is extended, it cooperates with the lock hole on the side of the display screen 11 to lock the display screen 11. When the lock tongue 93 is retracted, the lock tongue 93 leaves the lock hole of the display screen 11 to release the constraint, so that the display screen 11 is flipped under the drive of the flip drive mechanism 7. Among them, the gear transmission assembly is not shown in the figure, but the figure shows the gear transmission assembly installation position 92.

[0056] Optionally, the locking mechanism 9 can use linear drive elements such as electric push rods, slide rails and sliders to perform linear extension and retraction to achieve locking and unlocking of the display screen 11.

[0057] Preferably, the insertion position of the lock tongue 93 is designed according to the thickness of the display screen 11. The closer the insertion position of the lock tongue 93 is to the unfolded side of the display screen 11, the better the refined feeling. For example, the thickness of the display screen gradually decreases from one end of the rotation connection to the opposite free end, and its cross-sectional shape perpendicular to the main rotation axis of the display screen forms a triangular shape. Therefore, the closer to the unfolded side of the display screen 11, the thinner the thickness of the display screen is, which is not conducive to setting the lock hole. At this time, the position where the lock tongue is inserted into the display screen is close to the center of the width of the display screen, and the center position is selected to be biased towards the unfolded side of the display screen, which can not only meet the requirement of setting the lock hole for the thickness of the display screen, but also play a reliable supporting role under bumpy road conditions. In this case, the display screen has a better unfolded refined feeling.

[0058] A flip driving mechanism 7 and a flip supporting mechanism 8 are respectively designed on opposite sides of the display screen 11; the flip driving mechanism 7 and the flip supporting mechanism 8 are both connected to the display via a rotating shaft, the flip driving mechanism 7 provides a flip driving force, and the flip supporting mechanism 8 assists in flipping.

[0059] like Figure 4 , Figures 7 to 9 As shown, the flip driving mechanism 7 includes a flip driving motor 71 and a gear box 72, which transmit power to the main shaft through gears, and the main shaft is connected to the display screen 11; the flip supporting mechanism 8 includes a supporting shaft, and the supporting shaft is connected to the display screen 11; when the display screen 11 is unfolded, the locking tongue 93 of the locking mechanism 9 withdraws, and the flip driving motor 71 transmits the torque to the gear box 72, and the gear box 72 transmits the torque to the main shaft, thereby realizing the unfolding movement of the display; when retracting after the display, the flip driving motor 71 moves in the opposite direction, and after being retracted into place, the locking tongue 93 extends out to lock the display screen 11.

[0060] Preferably, the flip driving mechanism 7 and the flip supporting mechanism 8 are both designed with damping in a certain proportion, which provides a holding force to prevent the display screen 11 from shaking when flipping and enhance the elegance of the unfolding and retracting of the display screen 11. Specifically, dampers 73 are installed on the main shaft and the supporting shaft respectively.

[0061] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0062] Based on the same inventive concept, an embodiment of the present application also provides a vehicle equipped with the above-mentioned ceiling screen installation structure.

[0063] The vehicle provided by the embodiment of the utility model is equipped with a ceiling screen which can be pre-installed and hung on the roof sheet metal, and then the hands are free to fasten the ceiling screen, which is simple and convenient to install and disassemble, saving time and effort.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
