[0050] 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.

[0051] Below, reference is made to Figures 1 - 5 Describe the adjustment mechanism 100 of the display screen according to an embodiment of the present invention. The adjustment mechanism 100 of the display screen is applied to a vehicle, and the display screen can be a ceiling screen of the vehicle.

[0052] As Figure 3 and Figure 4As shown, the adjustment mechanism 100 of the display screen according to the present utility model includes: a first driving member 110, a first mounting seat 120, a second mounting seat 130, and a first lead screw 140. One of the first mounting seat 120 and the second mounting seat 130 is used for mounting the display screen 300 and the other is adapted to be mounted on the vehicle roof. The first lead screw 140 is rotatably disposed in the first mounting seat 120 and is in transmission connection with the first driving member 110. The second mounting seat 130 is in threaded cooperation with the first lead screw 140 to enable the second mounting seat 130 to move up and down relative to the first mounting seat 120.

[0053] It can be understood that the first driving member 110, the first mounting seat 120, the second mounting seat 130, and the first lead screw 140 constitute the main body of the adjustment mechanism 100 of the display screen. For example, the first mounting seat 120 is connected to the vehicle roof, and the display screen 300 is mounted on the second mounting seat 130, so that the second mounting seat 130 can limit the display screen 300, which is convenient for the installation and disassembly of the display screen 300. The upper end of the first lead screw 140 is connected to the first mounting seat 120, and the first driving member 110 is in transmission connection with the first lead screw 140, so that the driving force of the first driving member 110 can be transmitted to the second mounting seat 130 through the rotation of the first lead screw 140. Such a setting can enable the first 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 300 to move in the up and down direction relative to the vehicle roof, which is convenient for the driver and passengers to use the display screen 300. Another example is that the second mounting seat 130 is connected to the display screen 300, and the display screen 300 is mounted on the second mounting seat 130. The transmission mode of the first lead screw 140 is the same as the above mode. Using the first lead screw 140 for transmission cooperation can also ensure the translational stability of the adjustment mechanism 100 of the display screen.

[0054] According to the adjustment mechanism 100 of the display screen of the present utility model, by connecting the first mounting seat 120 and the second mounting seat 130 to the vehicle roof and the display screen 300 respectively, the driving force of the first driving member 110 and the first lead screw 140 can make the second mounting seat 130 move in the up and down direction relative to the first mounting seat 120, so that the display screen 300 can move relative to the vehicle roof, thereby improving the use experience of the driver and passengers.

[0055] Among them, such as Figure 3As shown, a nut is provided inside the second mounting seat 130, and the nut is in threaded engagement with the first lead screw 140. Such a setting can place the nut inside 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 adjustment mechanism 100 of the display screen. Moreover, the nut and the first lead screw 140 are in threaded engagement, so that the driving force of the first driving member 110 can be transmitted to the first mounting seat 120 through the rotation of the first lead screw 140, and there is no need to separately provide a threaded hole in the second mounting seat 130, and thus the second mounting seat 130 can move relative to the first mounting seat 120.

[0056] In addition, as Figure 3 shown, the adjustment mechanism 100 of the display screen further includes: a guide rod 150, the guide rod 150 is arranged on the first mounting seat 120 and is arranged in parallel with the first lead screw 140, the second mounting seat 130 is provided with a guide hole 131, and the guide rod 150 passes through the guide hole 131. That is to say, the guide rod 150 is located inside the first mounting seat 120, and the upper and lower ends of the guide rod 150 are respectively fixed to the upper and lower ends of the first mounting seat 120, so that the guide rod 150 and the first mounting seat 120 can be connected into a whole. The guide rod 150 and the first lead screw 140 are arranged at intervals left and right, and the guide rod 150 and the first lead screw 140 are arranged in parallel, so that the guide rod 150 can provide a guiding effect on the first lead screw 140. The second mounting seat 130 is provided with a guide hole 131, and the guide hole 131 is arranged corresponding to the guide rod 150, so that the guide rod 150 can pass through the guide hole 131, and thus it is convenient for the second mounting seat 130 to move relative to the guide rod 150.

[0057] Particularly, as Figure 3 shown, there are multiple guide rods 150, and the multiple guide rods 150 are located on opposite sides of the first lead screw 140. There are multiple guide holes 131, and the multiple guide holes 131 are in one-to-one correspondence with the multiple guide rods 150. It can be understood that two guide rods 150 are respectively located on the left and right sides of the first lead screw 140, so that the first lead screw 140 can be located between the two guide rods 150, and thus it is convenient for the guide rod 150 to provide a guiding effect on the first lead screw 140. Two guide holes 131 are provided on the second mounting seat 130, and the two guide rods 150 correspond to the two guide holes 131 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.

[0058] Among them, as Figure 3As shown, a first bearing 132 is provided in the guiding hole 131, and the guiding rod 150 passes through the first bearing 132. The first bearing 132 is a linear bearing. Such a setting enables the second mounting seat 130 to move linearly relative to the guiding rod 150, thereby facilitating the up-and-down movement of the second mounting seat 130 relative to the first mounting seat 120, and further facilitating the up-and-down movement of the display screen 300 relative to the vehicle roof.

[0059] In particular, as Figure 4 shown, a rotating part 126 is provided on the other one of the first mounting seat 120 and the second mounting seat 130, and the rotating part 126 is rotatable relative to the vehicle roof. It can be understood that the rotating part 126 is provided on the first mounting seat 120 and the rotating part 126 is rotatable relative to the vehicle roof, so that the rotating part 126 can provide a rotating force for the display screen 300, and further enable the display screen 300 to be opened or closed relative to the vehicle roof.

[0060] In addition, as Figure 3 shown, the first mounting seat 120 includes: a first seat body 121, a connecting plate 122 and a second seat body 123. The first seat body 121 is provided with a rotating part 126. The first driving member 110 is disposed in the first seat body 121. One end of the first lead screw 140 passes through the first seat body 121 and is in transmission connection with the first driving member 110. The connecting plate 122 is connected to the first seat body 121. The second seat body 123 is disposed on the connecting plate 122. The second seat body 123 is spaced apart from the first seat body 121 and the second mounting seat 130 is located between the first seat body 121 and the second seat body 123. The other end of the first lead screw 140 passes through the second seat body 123. That is to say, the connecting plate 122, the first seat body 121 and the second seat body 123 constitute the main structure of the first mounting seat 120. The rotating part 126 is located on the first seat body 121, so that the first seat body 121 can be connected to the vehicle roof. The first seat body 121 and the second seat body 123 are disposed on the connecting plate 122, and the first seat body 121 and the second seat body 123 are respectively located at the upper and lower ends of the connecting plate 122, so that a moving space can be formed between the first seat body 121 and the second seat body 123, thereby facilitating the movement of the second mounting seat 130 in the moving space. The first driving member 110 is located in the first seat body 121, so that the first seat body 121 can protect the first driving member 110, and further extend the service life of the first driving member 110. The upper end of the first lead screw 140 is disposed in the first seat body 121, and this end of the first lead screw 140 is connected to the first driving member 110, so that the driving force of the first driving member 110 can be transmitted to the first lead screw 140. The lower end of the first lead screw 140 passes through the second seat body 123, so that the rotation of the first 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.

[0061] Optionally, as Figure 3 and Figure 4 shown, on one side of the first base 121 facing the second mounting base 130, a first anti-collision pad 124 is provided, and on one side of the second base 123 facing the second mounting base 130, a second anti-collision pad 125 is provided. With such a setting, when the second mounting base 130 moves between the first base 121 and the second base 123, it can prevent the upper and lower ends of the second mounting base 130 from colliding with the first base 121 and the second base 123. Also, the first anti-collision pad 124 and the second anti-collision pad 125 can limit the position of the second mounting base 130, thereby protecting the second mounting base 130 and limiting the moving distance of the second mounting base 130.

[0062] In addition, as Figure 3 shown, the second mounting base 130 is provided with a first support leg 133 and a second support leg 134. The first support leg 133 and the second support leg 134 are located on opposite sides of the connecting plate 122, and the first support leg 133 and the second support leg 134 are adapted to be respectively connected to the display screen 300. That is to say, the first support leg 133 and the second support leg 134 are provided at the left and right ends of the second mounting base 130, and the first support leg 133 and the second support leg 134 are located on the left and right sides of the connecting plate 122, and both the first support leg 133 and the second support leg 134 are connected to the display screen 300, thus facilitating the connection between the second mounting base 130 and the display screen 300, and the first support leg 133 and the second support leg 134 do not affect the movement of the second mounting base 130 relative to the first mounting base 120, and further facilitating the movement of the display screen 300 relative to the first mounting base 120.

[0063] In addition, as Figure 3 and Figure 4 shown, the first base 121 forms an inner cavity, and one end of the first driving member 110 and the first lead screw 140 is disposed in the inner cavity. It can be understood that an inner cavity is formed inside the first base 121, so that the inner cavity can form a receiving space for components. The upper ends of the first driving member 110 and the first lead screw 140 are located in the inner cavity, so that the inner cavity can protect the upper ends of the first driving member 110 and the first lead screw 140, and further extend the service life of the upper ends of the first driving member 110 and the first lead screw 140.

[0064] In addition, as Figure 3As shown, the adjustment mechanism 100 of the display screen further includes: a first transmission assembly 160. The first transmission assembly 160 is disposed in the inner cavity and is respectively in transmission connection with one end of the first driving member 110 and the first lead screw 140. That is to say, the first transmission assembly 160 is located in the inner cavity, so that the inner cavity can protect the first transmission assembly 160, thereby extending the service life of the first transmission assembly 160. Moreover, the first transmission assembly 160 is connected between the first driving member 110 and the first lead screw 140, so that after the driving force of the first driving member 110 is transmitted to the first transmission assembly 160, the power can be transmitted to the first lead screw 140 to make it rotate.

[0065] In addition, as Figure 4 shown, the adjustment mechanism 100 of the display screen further includes: a bearing seat 170 and a second bearing 180. The bearing seat 170 is adapted to be connected to the vehicle roof, and the second bearing 180 is disposed between the other of the first mounting seat 120 and the second mounting seat 130 and the bearing seat 170. It can be understood that the bearing seats 170 are located at the left and right ends of the first seat body 121, and the upper surface of the bearing seat 170 is connected to the vehicle roof, so that the bearing seat 170 can limit the second bearing 180. Moreover, the second bearing 180 connects the first seat body 121 and the bearing seat 170, so that the first seat body 121 can be connected to the second bearing 180, and further the rotating part 126 can rotate relative to the bearing seat 170. For example, the second bearing 180 is a deep groove ball bearing, which can reduce the frictional resistance between the rotating part 126 and the bearing seat 170, and further improve the rotation speed of the rotating part 126.

[0066] In addition, as Figure 4 shown, the adjustment mechanism 100 of the display screen further includes: a gravity balance member 190. One end of the gravity balance member 190 is connected to the other of the first mounting seat 120 and the second mounting seat 130 and the other end is connected to the bearing seat 170. That is to say, the gravity balance member 190 is connected between the first seat body 121 and the bearing seat 170, so that the first seat body 121 can compress and release the gravity balance member 190 through its own linear motion, thereby improving the motion stability of the display screen 300. For example, the gravity balance member 190 is a coil spring, so that the gravity balance member 190 provides an elastic force for the second transmission member, the first seat body 121 and the second mounting seat 130, which is convenient for using gravity balance to balance the gravity of the display screen 300. Moreover, the gravity balance has good stability for the display screen 300 and occupies a small space, which can save the occupied space of the vehicle roof.

[0067] In addition, as Figure 4As shown, the adjustment mechanism 100 of the display screen further includes: a second driving member 200 and a second transmission assembly 210, and the second transmission assembly 210 is respectively connected to the second driving member 200 and the other of the first mounting seat 120 and the second mounting seat 130 to drive the other of the first mounting seat 120 and the second mounting seat 130 to rotate. It can be understood that the driving force of the second driving member 200 can be transmitted to the rotating part 126 through the second transmission assembly 210, so that the rotating part 126 can be rotated, and then the display screen 300 can be rotated.

[0068] Among them, Figure 4 As shown, the second transmission assembly 210 includes: an input member 211 and an output member 212, the input member 211 is arranged on the driving shaft of the second driving member 200, the output member 212 is sleeved on the other of the first mounting seat 120 and the second mounting seat 130, and the output member 212 is connected to the input member 211.
