[0034] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0035] Reference will be made below Figures 1-6 to describe the translation mechanism 110 of the display screen according to an embodiment of the present invention. The translation mechanism 110 of the display screen is applied to a vehicle, and the display screen can be a ceiling screen of the vehicle.

[0036] As Figures 1-6 shown, the translation mechanism 110 of the display screen according to the present invention includes: a driving member, a first mounting seat 120, a second mounting seat 130, and a lead screw 140. One of the first mounting seat 120 and the second mounting seat 130 is used to mount the display screen 100 and the other is mounted on the vehicle roof. The lead screw 140 is rotatably disposed on the first mounting seat 120 and is in transmission connection with the driving member. The second mounting seat 130 is in threaded cooperation with the lead screw 140 so that the second mounting seat 130 moves relative to the first mounting seat 120.

[0037] It can be understood that the driving member, the first mounting seat 120, the second mounting seat 130, and the lead screw 140 constitute the main body of the translation mechanism. For example, the first mounting seat 120 is connected to the vehicle roof, and the display screen 100 is mounted on the second mounting seat 130. Thus, the second mounting seat 130 can limit the display screen 100, which is convenient for the installation and disassembly of the display screen 100. The lead screw 140 is connected to the first mounting seat 120, and the driving member is in transmission connection with the lead screw 140. Thus, the driving force of the driving member can be transmitted to the first mounting seat 120 through the rotation of the lead screw 140. Such a setting can enable the lead screw 140 to convert its rotational motion into the movement of the second mounting seat 130, so that the second mounting seat 130 can drive the display screen 100 to move relative to the vehicle roof, which is convenient for the driver and passengers to use the display screen 100. Another example is that the second mounting seat 130 is connected to the display screen 100, the display screen 100 is mounted on the first mounting seat 120, and the transmission mode of the lead screw 140 is the same as the above method. Using the lead screw 140 for transmission cooperation can also ensure the translation stability of the translation mechanism 110.

[0038] Thus, by connecting the first mounting seat 120 and the second mounting seat 130 to the vehicle roof and the display screen 100 respectively, the driving force of the driving member and the lead screw 140 can cause the second mounting seat 130 to move relative to the first mounting seat 120, so that the display screen 100 can move relative to the vehicle roof, thereby improving the use experience of the driver and passengers.

[0039] Among them, as Figure 3 shown, a nut is provided in the second mounting seat 130, and the nut is in threaded cooperation with the lead screw 140. Such a setting can make the nut located in the second mounting seat 130, so that the second mounting seat 130 can protect the nut, thereby extending the service life of the nut and improving the convenience of the translation mechanism 110 of the display screen. Moreover, the nut and the lead screw 140 are in threaded cooperation, so that the driving force of the driving member can be transmitted to the first mounting seat 120 through the rotation of the lead screw 140, and there is no need to separately provide a threaded hole in the second mounting seat 130, so that the first mounting seat 120 can move relative to the second mounting seat 130.

[0040] In addition, as Figure 3 shown, the translation mechanism 110 of the display screen further includes: a guide rod 150, the guide rod 150 is arranged in the first mounting seat 120 and is arranged parallel to the lead screw 140, the second mounting seat 130 is provided with a guide hole, and the guide rod 150 passes through the guide hole. That is to say, the guide rod 150 is located in the first mounting seat 120, and the two transverse ends of the guide rod 150 are respectively fixed to the two transverse ends of the first mounting seat 120, so that the guide rod 150 and the first mounting seat 120 are connected into a whole. The guide rod 150 and the lead screw 140 are longitudinally spaced apart and are arranged parallel to each other, so that the guide rod 150 can provide a guiding effect on the lead screw 140. The second mounting seat 130 is provided with a guide hole, and the guide hole is correspondingly arranged with the guide rod 150, so that the guide rod 150 can pass through the guide hole, thereby facilitating the movement of the second mounting seat 130 relative to the guide rod 150.

[0041] Particularly, as Figure 3 shown, there are a plurality of guide rods 150, the plurality of guide rods 150 are located on opposite sides of the lead screw 140, there are a plurality of guide holes, and the plurality of guide holes are in one-to-one correspondence with the plurality of guide rods 150. It can be understood that the two guide rods 150 are respectively located on the longitudinal sides of the lead screw 140, so that the lead screw 140 is located between the two guide rods 150, thereby facilitating the guide rod 150 to provide a guiding effect on the lead screw 140. The second mounting seat 130 is provided with two guide holes, and the two guide rods 150 correspond to the two guide holes one by one, so that it is convenient for the second mounting seat 130 to move relative to the guide rod 150 and can ensure the movement stability of the second mounting seat 130.

[0042] Among them, asFigure 3 As shown, a linear bearing is provided in the guiding hole, and the guiding rod 150 passes through the linear bearing. Such a setting enables the second mounting seat 130 to move linearly relative to the guiding rod 150, thereby facilitating the lateral movement of the second mounting seat 130 relative to the first mounting seat 120, and further facilitating the lateral movement of the display screen 100 relative to the vehicle roof.

[0043] In addition, as Figure 3 shown, the first mounting seat 120 includes: a bottom plate 121, a first seat body 122, and a second seat body 123. The first seat body 122 is disposed on the bottom plate 121, the driving member is disposed in the first seat body 122, one end of the lead screw 140 passes through the first seat body 122 and is in transmission connection with the driving member, the second seat body 123 is disposed on the bottom plate 121, the second seat body 123 is spaced apart from the first seat body 122, and the second mounting seat 130 is located between the first seat body 122 and the second seat body 123, and the other end of the lead screw 140 passes through the second seat body 123. That is to say, the bottom plate 121, the first seat body 122, and the second seat body 123 constitute the main structure of the first mounting seat 120. The first seat body 122 and the second seat body 123 are disposed on the bottom plate 121, and the first seat body 122 and the second seat body 123 are respectively located at the lateral two ends of the bottom plate 121, so that a moving space can be formed between the first seat body 122 and the second seat body 123, thereby facilitating the movement of the second mounting seat 130 within the moving space. The driving member is located in the first seat body 122, so that the first seat body 122 can protect the driving member, and further the service life of the driving member can be extended. One end of the lead screw 140 is disposed in the first seat body 122, and this section of the lead screw 140 is connected to the driving member, so that the driving force of the driving member can be transmitted to the lead screw 140. The other end of the lead screw 140 passes through the second seat body 123, so that the rotation of the lead screw 140 can drive the translation of the second mounting seat 130, and further facilitate the movement of the second mounting seat 130 relative to the first mounting seat 120.

[0044] Optionally, as Figure 3 shown, a first anti-collision pad 124 is provided on the side of the first seat body 122 facing the second mounting seat 130, and a second anti-collision pad 125 is provided on the side of the second seat body 123 facing the second mounting seat 130. Such a setting can prevent the lateral two ends of the second mounting seat 130 from colliding with the first seat body 122 and the second seat body 123 when the second mounting seat 130 moves between the first seat body 122 and the second seat body 123, and the first anti-collision pad 124 and the second anti-collision pad 125 can also limit the second mounting seat 130, thereby protecting the second mounting seat 130 and limiting the moving distance of the second mounting seat 130.

[0045] In addition, as Figure 3As shown in the figure, the translation mechanism 110 of the display screen further includes: a connecting plate 160, which is used to mount the display screen 100, and one of the second mounting seat 130 and the first mounting seat 120 is mounted to the display screen 100 through the connecting plate 160. It can be understood that the connecting plate 160 is located at the bottom ends of the first mounting seat 120 and the second mounting seat 130, and the connecting plate 160 is connected to the second mounting seat 130. The display screen 100 can be accommodated below the connecting plate 160, so that the display screen 100, the connecting plate 160 and the second mounting seat 130 can be connected. Furthermore, the translation of the second mounting seat 130 can drive the display screen 100 to move.

[0046] In addition, as Figure 3 shown in the figure, the second mounting seat 130 is provided with a first support leg 131 and a second support leg 132. The first support leg 131 and the second support leg 132 are located on opposite sides of the first mounting seat 120, and the first support leg 131 and the second support leg 132 are respectively connected to the connecting plate 160. That is to say, the first support leg 131 and the second support leg 132 are provided at the longitudinal two ends of the second mounting seat 130, and the first support leg 131 and the second support leg 132 are located on the longitudinal two sides of the first mounting seat 120. Both the first support leg 131 and the second support leg 132 are connected to the connecting plate 160, which is convenient for connecting the second mounting seat 130 and the connecting plate 160. Moreover, the first support leg 131 and the second support leg 132 do not affect the movement of the second mounting seat 130 relative to the first mounting seat 120. Furthermore, it is convenient for the connecting plate 160 to move relative to the first mounting seat 120 after connecting the display screen 100.

[0047] As Figure 1 and Figure 2 shown in the figure, the display screen 100 device according to the present invention includes: a display screen 100 and the translation mechanism 110 of the display screen in the above embodiment. The display screen 100 is rotatably connected to one of the first mounting seat 120 and the second mounting seat 130. It can be understood that the display screen 100 and the translation mechanism 110 constitute the main structure of the display screen 100 device. The translation mechanism 110 can move the display screen 100 relative to the vehicle roof, and the display screen 100 can rotate relative to the first mounting seat 120. Thus, the display screen 100 can have the functions of moving and rotating, and further improve the use experience of the driver and passengers.

[0048] As Figures 1-6As shown, the display screen 100 device further includes: a mounting structure 200, the mounting structure 200 is mounted on the vehicle roof, and the other of the first mounting seat 120 and the second mounting seat 130 is mounted on the vehicle roof through the mounting structure 200. That is to say, the mounting structure 200 is located at the vehicle roof, and the mounting structure 200 is fixedly connected to the vehicle roof. When not in use, the display screen 100 is located within the mounting structure 200. When in use, the display screen 100 can rotate relative to the mounting structure 200, thereby saving the occupied space of the display screen 100. The first mounting seat 120 is arranged at the vehicle roof, facilitating the movement of the second mounting seat 130 relative to the first mounting seat 120. The mounting structure 200 can form an integral structure with the display screen 100 and then be integrally mounted on the vehicle roof, which can simplify the installation steps of the display screen 100 and reduce the installation difficulty of the display screen 100. Herein, the vehicle roof is the vehicle ceiling. Of course, the display screen 100 device can also omit the mounting structure 200 and use the vehicle roof as the mounting carrier.

[0049] Among them, as Figure 1 shown, the mounting structure 200 is formed with a receiving groove 210 for receiving the display screen 100, and the translation mechanism is located within the receiving groove 210. It can be understood that the mounting structure 200 internally forms the receiving groove 210, and the receiving groove 210 can provide a placement space for the display screen 100 and allow the display screen 100 to be opened and closed, thereby saving the occupied space of the display screen 100. The translation mechanism is located within the receiving groove 210, thus providing a movement space for the translation mechanism.

[0050] In addition, as Figure 1 shown, the mounting structure 200 includes: a fixing plate 220 and a top cover 230. The fixing plate 220 is adapted to be mounted on the vehicle roof. The fixing plate 220 is connected to the other of the first mounting seat 120 and the second mounting seat 130. The top cover 230 is mounted on the fixing plate 220, and the top cover 230 defines the receiving groove 210. That is to say, the fixing plate 220 and the top cover 230 constitute the main structure of the mounting structure 200. The fixing plate 220 is connected to the vehicle roof, enabling the mounting structure 200 to be fixed on the vehicle roof, thereby making the mounting structure 200 more firm. The first mounting seat 120 is connected to the fixing plate 220, facilitating the control of the second mounting seat 130 to move relative to the first mounting seat 120 by the lead screw 140. The top cover 230 is arranged on the fixing plate 220, so that a receiving groove 210 is formed between the top cover 230 and the fixing plate 220, thus facilitating the installation of the display screen 100 and the translation mechanism in the mounting structure 200.

[0051] In addition, as Figure 2As shown in the figure, the display screen 100 device further includes: an electromagnetic lock 300, which is arranged on the mounting structure 200 and is used to lock the display screen 100 in the current position. It can be understood that the electromagnetic lock 300 is located on the mounting structure 200. When the display screen 100 is not in use, it is stored in the receiving groove 210, so that the electromagnetic lock 300 can lock the display screen 100, and further prevent the display screen 100 from shaking during driving. The electromagnetic lock 300 can control the extension and retraction of the locking tongue through electromagnetic force, so as to lock the display screen 100.

[0052] In addition, as Figure 3 shown in the figure, the display screen 100 device further includes: a driving mechanism 400, which is installed on the mounting structure 200 and is located on one side of the display screen 100. A rotating shaft 410 is provided on one side of the display screen 100. The driving mechanism 400 is in transmission connection with the rotating shaft 410, so that the display screen 100 can be driven to rotate through the rotating shaft 410. That is to say, the driving mechanism 400 is located within the mounting structure 200, and the driving mechanism 400 is located on the lateral side of the display screen 100. A rotating shaft 410 is provided on the side of the display screen 100 close to the driving mechanism 400, so that the driving mechanism 400 and the rotating shaft 410 can be connected, and further the driving mechanism 400 can provide a driving force for the display screen 100 to rotate.

[0053] Among them, as Figure 3 shown in the figure, the driving mechanism 400 includes: a driving part, a transmission component and a mounting shaft. The driving part is installed on the mounting structure 200, the transmission component is in transmission connection with the driving part, the mounting shaft is in transmission connection with the transmission component, the mounting shaft is installed on the rotating shaft 410, and the mounting shaft rotates synchronously with the rotating shaft 410. Such a setting can connect the driving part, the transmission component, the mounting shaft and the rotating shaft 410 in sequence, so that the driving force of the driving part can be transmitted to the display screen 100 through the transmission component, the mounting shaft and the rotating shaft 410, and further the display screen 100 can rotate.

[0054] In addition, as Figure 3 shown in the figure, the driving mechanism 400 further includes: a stop component. The mounting shaft is provided with a first stop part. The stop component is sleeved on the mounting shaft. The stop component and the first stop part are arranged at intervals in the axial direction of the mounting shaft. The output part is blocked between the first stop part and the stop component, so as to facilitate the driving force to be transmitted to the mounting shaft through the output part, avoid the position change of the output part, and ensure the stability of power transmission.

[0055] In addition, as Figure 3As shown, the driving mechanism 400 is in spline fit with the rotating shaft 410. Such a setting can improve the stress-bearing strength between the driving mechanism 400 and the rotating shaft 410, thereby improving the structural strength between the driving mechanism 400 and the rotating shaft 410, and further improving the structural strength between the driving mechanism 400 and the display screen 100.

[0056] The vehicle according to an embodiment of the present invention includes the display screen 100 device of the above embodiment. The display screen 100 device arranged in this way can make the display screen 100 move horizontally relative to the vehicle roof and open and close.
