[0051] At present, the ceiling screen structure includes a base and a display screen rotatably mounted on the base. The base is provided with a driving device for driving the display screen to rotate. The driving device usually includes a driving motor and a gear set. The gear set drives the display screen to rotate through a rotating shaft. The gear set can reduce the speed of the driving motor and increase the driving torque. Since there is a gap when the gear set is matched, when the vehicle is driving on a bumpy road, the display screen will be impacted and cause shaking, affecting the viewing experience. At the same time, the impact will be transmitted to the gears, causing damage to the gears.

[0052] In order to solve the above problems, a damping structure is usually set at the rotating shaft. However, the damping structure is greatly affected by factors such as assembly tolerance and temperature, which causes the damping force of the damping structure to change, making the stability of the damping structure poor, and the display screen may still shake when the ceiling is impacted.

[0053] In order to solve the problem of display screen shaking caused by impact on the ceiling, the applicant has designed a display screen mounting device, a ceiling screen assembly and a vehicle after in-depth research.

[0054] The first embodiment of the present application provides a display screen installation device. Figures 5 to 7 The display screen installation device includes a base 11 and a connecting member 13. The base 11 is used to install a display screen 12.

The connecting member 13 includes a first magnetic member 131 and a second magnetic member 132 and a third magnetic member 133 fixed on the base 11. The first magnetic member 131 is used to be fixed on the display screen 12 at a position corresponding to the second magnetic member 132 and / or the third magnetic member 133, wherein

[0055] When the display screen 12 is in a closed state, the first magnetic member 131 and the second magnetic member 132 are attracted to each other; and / or, when the display screen 12 is in an open state, the first magnetic member 131 and the third magnetic member 133 are attracted to each other.

[0056] It can be understood that the base 11 and the roof of the vehicle can be two components, and the base 11 is fixed to the roof of the vehicle by welding, clamping, fastener connection, etc.; or, the base 11 can be a part of the roof of the vehicle.

[0057] The display screen 12 can rotate relative to the base 11 to be in an open state and a closed state. It can be understood that the display screen 12 can be manually driven to rotate relative to the base 11, or the display screen 12 can be automatically driven to rotate relative to the base 11 by the driving device 15. When the display screen 12 is in the closed state, the angle between the display screen 12 and the base 11 is 0° or close to 0°; when the display screen 12 is in the open state, the angle between the display screen 12 and the base 11 can be 90° or close to 90°.

[0058] The first magnetic member 131 is used to be fixed on the display screen 12. It can be understood that the first magnetic member 131 can be fixed on the display screen 12 by bonding; or, the first magnetic member 131 can be fixed on the display screen 12 by snapping; or, the first magnetic member 131 can be fixed on the display screen 12 by interference fit; or, the first magnetic member 131 can be fixed on the display screen 12 by fastener connection.

[0059] The second magnetic member 132 and the third magnetic member 133 are fixed on the base 11. It can be understood that the second magnetic member 132 and the third magnetic member 133 can be fixed on the base 11 by bonding; or, the second magnetic member 132 and the third magnetic member 133 can be fixed on the base 11 by snapping; or, the second magnetic member 132 and the third magnetic member 133 can be fixed on the base 11 by interference connection; or, the second magnetic member 132 and the third magnetic member 133 can be fixed on the base 11 by fastener connection.

[0060] The first magnetic component 131 is used to be fixed on the display screen 12 at a position corresponding to the second magnetic component 132 and / or the third magnetic component 132. It can be understood that after the first magnetic component 131 is fixed on the display screen 12, the first magnetic component 131 is arranged correspondingly to the second magnetic component 132; or, after the first magnetic component 131 is fixed on the display screen 12, the first magnetic component 131 is arranged correspondingly to the third magnetic component 133; or, after the first magnetic component 131 is fixed on the display screen 12, the first magnetic component 131 is arranged correspondingly to the second magnetic component 132 and the third magnetic component 133 at the same time.

[0061] When the first magnetic member 131 and the second magnetic member 132 are arranged correspondingly, the display screen 12 is rotated to the closed state, and the first magnetic member 131 and the second magnetic member 132 are closely attached and attracted to fix the display screen 12 in the closed state. Figure 5As shown. It can be understood that the first magnetic member 131 and the second magnetic member 132 can both be magnets, and the magnetic properties of the two are opposite. The magnetic attraction between the first magnetic member 131 and the second magnetic member 132 is relatively large, and the stability of the display screen 12 in the closed state is relatively high; or, the first magnetic member 131 is a magnet, and the second magnetic member 132 is a magnetic member made of materials such as iron, nickel or cobalt; or, the first magnetic member 131 is a magnetic member made of materials such as iron, nickel or cobalt, and the second magnetic member 132 is a magnet.

[0062] When the first magnetic member 131 and the third magnetic member 133 are arranged correspondingly, the display screen 12 is rotated to the open state, and the first magnetic member 131 and the third magnetic member 133 are closely attached and attracted to fix the display screen 12 in the open state. Figure 6 It can be understood that the first magnetic member 131 and the third magnetic member 133 are both magnets, and the magnetic properties of the two are opposite. The magnetic attraction between the first magnetic member 131 and the third magnetic member 133 is relatively large, and the stability of the display screen 12 when in the open state is relatively high; or, the first magnetic member 131 is a magnet, and the third magnetic member 133 is a magnetic member made of materials such as iron, nickel or cobalt; or, the first magnetic member 131 is a magnetic member made of materials such as iron, nickel or cobalt, and the third magnetic member 133 is a magnet.

[0063] It can be understood that the shape of any one of the first magnetic member 131 , the second magnetic member 132 and the third magnetic member 133 can be rectangular, oblong, circular, elliptical, oval or other shapes.

[0064] The number of any one of the first magnetic component 131 , the second magnetic component 132 and the third magnetic component 133 may be one or more.

[0065] The beneficial effects of the display screen mounting device provided by the embodiment of the present application are as follows: when in use, the first magnetic member 131 is mounted on the display screen 12, and the display screen 12 is mounted on the display screen mounting device. When the display screen 12 is in a closed state, the first magnetic member 131 and the second magnetic member 132 are attracted to fix the display screen 12 in a closed state; and / or, when the display screen 12 is in an open state, the first magnetic member 131 and the third magnetic member 133 are attracted to fix the display screen 12 in an open state. Since the magnetic attraction force is relatively large, and the magnetic attraction force is not affected by factors such as assembly tolerance, temperature, and fatigue life, the stability of the display screen 12 in the closed state and the open state can be ensured, and the problem of the display screen 12 shaking when the ceiling is impacted is solved.

[0066] Please refer to Figure 8 and Fig. 9In some embodiments, the connecting member 13 further includes a fourth magnetic member 134 , and the fourth magnetic member 134 is used to be fixed at a position on the display screen 12 corresponding to the second magnetic member 132 .

[0067] When the display screen 12 is in a closed state, the fourth magnetic member 134 and the second magnetic member 132 are attracted to each other; when the display screen 12 is in an open state, the first magnetic member 131 and the third magnetic member 133 are attracted to each other.

[0068] The position of the fourth magnetic member 134 is not limited, as long as the fourth magnetic member 134 can be attracted to the second magnetic member 132. For example, the fourth magnetic member 134 can be arranged at the swing end 122 of the display screen 12, such as Figure 8 As shown; at this time, when the display screen 12 is in the open state, the first magnetic member 131 and the third magnetic member 133 are attracted; when the display screen 12 is closed, the first magnetic member 131 is not attracted to the second magnetic member 132. The fourth magnetic member 134 can also be set at the rotating end 121 of the display screen 12, such as Fig. 9 As shown; at this time, when the display screen 12 is in the open state, the first magnetic member 131 is attracted to the third magnetic member 133, or the first magnetic member 131 and the fourth magnetic member 134 are attracted to the third magnetic member 133; when the display screen 12 is in the closed state, the first magnetic member 131 is attracted to the second magnetic member 132, or the first magnetic member 131 and the fourth magnetic member 134 are attracted to the second magnetic member 132.

[0069] Optionally, when the fourth magnetic member 134 is disposed at the rotating end 121 of the display screen 12 , the fourth magnetic member 134 and the first magnetic member 131 are stacked.

[0070] In other embodiments, when the connecting member 13 further includes a fourth magnetic member 134, the fourth magnetic member 134 is used to be fixed to a position on the display screen 12 corresponding to the third magnetic member 133. When the display screen 12 is in a closed state, the first magnetic member 131 and the second magnetic member 132 are attracted; when the display screen 12 is in an open state, the fourth magnetic member 134 and the third magnetic member 133 are attracted.

[0071] Please also refer to Figures 5 to 7 In some embodiments, the first magnetic member 131 is used to be fixed to the rotating end 121 of the display screen 12 .

[0072] The rotating end 121 of the display screen 12 refers to an end of the display screen 12 that rotates around a rotation axis (eg, a coaxially arranged driving rotation axis 151 and a driven rotation axis 161). Correspondingly, the second magnetic member 132 and the third magnetic member 133 are arranged close to the rotation axis around which the display screen 12 rotates.

[0073] Based on the above solution, when the display screen 12 is in the open state and the closed state, the first magnetic member 131 can be well hidden and not easily seen by the user, thereby improving the aesthetics of the display screen 12 .

[0074] Please refer to Figure 5 and Figure 6 In some embodiments, the base 11 includes a shell 111 for the rotating end 121 of the display screen 12 to rotate; wherein, the base 11 also includes a first fixed base 112 fixed on the shell 111, and the second magnetic member 132 is fixed on the first fixed base 112; the base 11 also includes a second fixed base 113 fixed on the shell 111, and the third magnetic member 133 is fixed on the second fixed base 113.

[0076] It can be understood that the first fixing seat 112 can be fixed on the shell 111 by welding, clamping, fastener connection, etc.

[0077] Optionally, the first fixing seat 112 is a plate-shaped structure, and the second magnetic member 132 is fixed to a side surface of the first fixing seat 112 facing the inner cavity 1111. It is understood that the second magnetic member 132 can be directly fixed to a side surface of the first fixing seat 112 facing the inner cavity 1111; or, a first groove is provided on a side surface of the first fixing seat 112 facing the inner cavity 1111, and the second magnetic member 132 is fixed in the first groove.

[0078] It can be understood that the second fixing seat 113 can be fixed on the housing 111 by welding, clamping, fastener connection, etc.

[0079] Optionally, the second fixing seat 113 is a T-shaped structure, and the third magnetic member 133 is fixed to a side surface of the second fixing seat 113 facing the inner cavity 1111. It is understood that the third magnetic member 133 can be directly fixed to a side surface of the second fixing seat 113 facing the inner cavity 1111; or, a second groove is provided on a side surface of the second fixing seat 113 facing the inner cavity 1111, and the third magnetic member 133 is fixed in the second groove.

[0080] By adopting the above technical solution, after the second magnetic component 132 is fixed on the first fixing seat 112, the first fixing seat 112 is fixed on the shell 111, which is beneficial to the installation of the second magnetic component 132; after the third magnetic component 133 is fixed on the second fixing seat 113, the second fixing seat 113 is fixed on the shell 111, which is beneficial to the installation of the third magnetic component 133.

[0081] In other embodiments, the base 11 includes a first fixing seat 112 fixed on the shell 111, and the second magnetic member 132 is fixed on the first fixing seat 112; the base 11 does not include the second fixing seat 113, and the third magnetic member 133 is directly fixed on the cavity wall of the shell 111. Alternatively, the base 11 does not include the first fixing seat 112, the shell 111 includes a flange at the same position as the first fixing seat 112, and the second magnetic member 132 is fixed on the flange; the base 11 includes a second fixing seat 113 fixed on the shell 111, and the third magnetic member 133 is fixed on the second fixing seat 113. Alternatively, the base 11 does not include the first fixing seat 112 and the second fixing seat 113, the shell 111 includes a flange at the same position as the first fixing seat 112, the second magnetic member 132 is fixed on the flange, and the third magnetic member 133 is directly fixed on the cavity wall of the shell 111.

[0082] Please refer to Figure 5 and Figure 6 In some embodiments, the second fixing seat 113 has an inclined surface 1131 , and the third magnetic member 133 is fixed on the inclined surface 1131 .

[0083] Optionally, the inclined surface 1131 is arranged toward the inner cavity 1111, and a second groove is provided on the inclined surface 1131, and the third magnetic member 133 is fixed in the second groove. Of course, the second groove may not be provided on the inclined surface 1131, and the third magnetic member 133 is directly fixed on the inclined surface 1131.

[0084] The inclined surface 1131 faces obliquely upward, so that the screen of the display screen 12 faces obliquely downward when the display screen 12 is in the open state.

[0085] By adopting the above technical solution, the display screen 12 has a certain tilt angle in the open state, so that the display screen 12 can face or substantially face the user on the seat, thereby improving the user's viewing experience.

[0086] Please refer to Figure 7 In some embodiments, the display screen mounting device further includes a locking member 14 movably disposed on the base 11 , and when the display screen 12 is in a closed state, the locking member 14 is used to lock the display screen 12 on the base 11 .

[0087] Optionally, the locking member 14 is a locking tongue disposed on the base 11 , and the display screen 12 is provided with a locking groove for inserting the locking tongue on the side of the display screen 12 in the extending direction of the rotation axis.

[0088] It is understood that one or more locking members 14 may be provided. When multiple locking members 14 are provided, a locking member 14 is provided on both sides of the display screen 12 in the extending direction of the rotation axis of the display screen 12. For example, when two locking members 14 are provided, a locking member 14 is provided on both sides of the display screen 12 in the extending direction of the rotation axis of the display screen 12.

[0089] The present application does not limit the driving mechanism of the locking member 14. For example, the driving mechanism may be an electromagnet driving mechanism, an electric push rod, etc.

[0090] By adopting the above technical solution, when the display screen 12 is in a closed state, the locking member 14 is used to lock the display screen 12 on the base 11 to prevent the display screen 12 from opening in an abnormal situation and causing a safety hazard.

[0091] Usually, the locking accuracy of the locking member 14 is poor, so the first magnetic member 131 and the second magnetic member 132 need to be attracted to each other to ensure that the display screen 12 does not shake when in the closed state.

[0092] The second aspect of the present application proposes a ceiling screen assembly 10 , which includes a display screen 12 and a display screen mounting device as described in the first aspect, and the display screen 12 is rotatably connected to a base 11 .

[0093] The ceiling screen assembly 10 adopts any one or more embodiments of the above-mentioned display screen mounting device, and thus has the beneficial effects of the above-mentioned embodiments, which will not be described one by one here.

[0094] Please refer to Figure 5 In some embodiments, the rotating end 121 of the display screen 12 is provided with a mounting plate 1211 , and the first magnetic member 131 is mounted on the mounting plate 1211 .

[0095] The first magnetic member 131 may be installed on one side of the mounting plate 1211 in the thickness direction.

[0096] Optionally, the mounting plate 1211 is provided with a third groove, and the first magnetic member 131 is installed in the third groove. Of course, the mounting plate 1211 may not be provided with the third groove, and the first magnetic member 131 is directly installed on the surface of the mounting plate 1211.

[0097] Optionally, the mounting plate 1211 is disposed on an end surface of the rotating end 121 of the display screen 12, and when the display screen 12 is in a closed state, the mounting plate 1211 is arranged horizontally or nearly horizontally.

[0098] Based on the above solution, since the first magnetic member 131 is not installed on the frame of the display screen 12, the display screen 12 can be designed with a narrow frame or no frame, which is beneficial to improving the user's viewing experience.

[0099] In other embodiments, the mounting plate 1211 may not be provided, and the first magnetic member 131 may be mounted on the frame of the display screen 12 .

[0100] Please also refer to Figure 5 and Figure 6 In some embodiments, a plurality of first magnetic members 131 are arranged at intervals along the extension direction of the rotation axis of the display screen 12; a plurality of second magnetic members 132 are arranged at intervals along the extension direction of the rotation axis of the display screen 12; and a plurality of third magnetic members 133 are arranged at intervals along the extension direction of the rotation axis of the display screen 12.

[0101] The rotation axis of the display screen 12 extends in the direction of Figure 7 Middle X direction.

[0102] It can be understood that there may be two, three or four first magnetic members 131. Optionally, the first magnetic member 131 is in a long strip shape.

[0103] It is understandable that the number of the second magnetic members 132 may be two, three or four, etc. Optionally, the second magnetic member 132 is in the shape of a long strip.

[0104] It can be understood that the third magnetic members 133 may be two, three or four, etc. Optionally, the second magnetic member 132 is in a long strip shape.

[0105] Optionally, the number of the first magnetic members 131 and the number of the second magnetic members 132 are the same and they are arranged in a one-to-one correspondence to increase the magnetic attraction between the first magnetic members 131 and the second magnetic members 132 .

[0106] Optionally, the number of the first magnetic members 131 and the number of the third magnetic members 133 are the same and they are arranged in a one-to-one correspondence to increase the magnetic attraction between the first magnetic members 131 and the third magnetic members 133 .

[0107] By adopting the above technical solution, the sizes of the first magnetic member 131, the second magnetic member 132 and the third magnetic member 133 can be increased, thereby increasing the magnetic attraction between the first magnetic member 131 and the second magnetic member 132 and the magnetic attraction between the first magnetic member 131 and the third magnetic member 133, further ensuring the stability of the display screen 12 in the closed state and the open state.

[0108] In other embodiments, a plurality of first magnetic members 131 are arranged at intervals along the direction in which the rotation axis of the display screen 12 extends, and a single second magnetic member 132 and a single third magnetic member 133 are each provided and are arranged along the direction in which the rotation axis of the display screen 12 extends. Alternatively, a single first magnetic member 131 and a single second magnetic member 132 are each provided and are arranged along the direction in which the rotation axis of the display screen 12 extends, and a plurality of third magnetic members 133 are arranged at intervals along the direction in which the rotation axis of the display screen 12 extends. Alternatively, a single first magnetic member 131 and a single third magnetic member 133 are each provided and are arranged along the direction in which the rotation axis of the display screen 12 extends, and a plurality of second magnetic members 132 are arranged at intervals along the direction in which the rotation axis of the display screen 12 extends. Alternatively, a single first magnetic member 131, a single second magnetic member 132, and a single third magnetic member 133 are each provided and are arranged along the direction in which the rotation axis of the display screen 12 extends.

[0109] Please refer to Figure 7 In some embodiments, a driving device 15 and an auxiliary device 16 are provided on the base 11. The driving device 15 provides an active rotating shaft 151 for flipping the display screen 12 and provides power for flipping the display screen 12; the auxiliary device 16 provides a driven rotating shaft 161 for flipping the display screen 12 and integrates an angle detection function.

[0110] The driving device 15 includes a driving motor and a gear set. Since the display screen 12 is not affected by the damping structure during the flipping process, the driving force requirements of the driving motor and the gear set are greatly reduced, so a smaller driving motor can be selected to reduce the transmission ratio, thereby reducing the packaging size of the entire driving motor and the gear set, thereby reducing the occupied space of the driving device 15, which is beneficial to the layout of the entire vehicle, and can also reduce costs and reduce noise.

[0111] The second aspect of the present application provides a vehicle. The vehicle includes a ceiling and a ceiling screen assembly 10 as described in the first aspect, and the ceiling screen assembly 10 is fixed on the ceiling. One or more ceiling screen assemblies 10 can be arranged on the ceiling according to the size of the vehicle. The vehicle can be a vehicle, an airplane, a train, etc.

[0112] The vehicle adopts any one or more embodiments of the above-mentioned ceiling screen assembly 10, and thus has the beneficial effects of the above-mentioned embodiments, which will not be described one by one here.
