Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a flip screen. Background Technology

[0002] In existing technologies, to improve user experience, vehicles are typically equipped with screens for customers to view videos, images, and other content. Among these, roof-mounted screens are often flip-up screens, which can be rotated as needed for angle adjustment or concealment. Current flip-up screens generally consist of a base and a display screen. The left end of the display screen is connected to an active mechanism to drive its rotation, while the right end is mounted to the base via a driven mechanism. Current flip-up screens rely on a single-sided active mechanism for rotation, with the left and right ends supported only by the active and driven mechanisms.

[0027] Reference Figure 1 and Figure 2A flip screen according to an embodiment of the present invention includes a base 110, a drive mechanism 200, and a display screen 300. The drive mechanism 200 includes an electric drive device 210 and two lead screws 220. The two lead screws 220 are arranged side by side and rotatably mounted on the base 110. Each lead screw 220 is screwed with a slider 230, which is slidably mounted on the base 110. Each lead screw 220 is equipped with a driven synchronous wheel 240. The electric drive device 210 is mounted on the base 110, and two output synchronous wheels 250 are mounted on the output shaft of the electric drive device 210. Wheel 250 is connected to two driven synchronous wheels 240 in a one-to-one transmission via synchronous belt 260. An overload protection device 270 is provided between the output shaft of electric drive device 210 and the output synchronous wheel 250. Display screen 300 is located between two sliders 230. The two opposite ends of display screen 300 are rotatably connected to the two sliders 230 in a one-to-one transmission. At least two connecting rods 400 are hinged between display screen 300 and base 110. When electric drive device 210 drives the two sliders 230 to slide, the two sliders 230 can drive display screen 300 to rotate relative to base 110.

[0028] In the flip screen provided by this utility model, the two ends of the display screen 300 are rotatably connected to two sliders 230 in a one-to-one correspondence. At the same time, at least two connecting rods 400 are hinged between the display screen 300 and the base 110. As a result, the installation of the display screen 300 is more reliable and stable. The electric drive device 210 can drive the display screen 300 to flip relative to the base 110 from both ends of the display screen 300 through the two sliders 230. During the flipping process of the display screen 300, the two sliders 230 and all connecting rods 400 can support the rotation of the display screen 300, making the flip screen run more smoothly and reducing the noise during operation. In addition, by setting an overload protection component 270 between the output shaft of the electric drive device 210 and the output synchronous wheel 250, overload protection is achieved, effectively preventing the drive mechanism 200 from overloading when the display screen 300 is obstructed from flipping, thus protecting the display screen 300 and the drive mechanism 200. When the display screen 300 is flipped to the desired angle, the lead screw 220 and the corresponding slider 230 can form a self-locking mechanism to lock the rotation angle of the display screen 300. Therefore, there is no need to set an additional locking device to lock the rotation angle of the display screen 300 when flipping the screen.

[0029] In the specific implementation process, the display screen 300 is located on one side of the base 110. The end of the display screen 300 near the base 110 is rotatably connected to the slider 230, and the middle part of the display screen 300 is rotatably connected to the connecting rod 400. Thus, the slider 230 can drive the display screen 300 to rotate. During the rotation of the display screen 300 relative to the base 110, both the end of the display screen 300 near the base 110 and the middle part of the display screen 300 can be supported, making the operation of the display screen 300 more stable, distributing the force on the display screen 300, and improving the load-bearing capacity of the display screen 300.

[0030] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the slider 230 is provided with a first connecting part 231 and a second connecting part 232. The first connecting part 231 is screw-driven with a corresponding lead screw 220, and the second connecting part 232 is located on one side of the first connecting part 231 and is rotatably connected to the display screen 300. This configuration facilitates the installation of the slider 230 and reduces its production cost.

[0031] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the slider 230 includes a sliding guide portion 233, a first connecting portion 231 and a second connecting portion 232 disposed on the sliding guide portion 233, and a guide groove 111 provided on the base 110, with the sliding guide portion 233 slidably mounted on the guide groove 111. With the above configuration, the slider 230 is easy to install, and the base 110 can guide the slider 230 using the guide groove 111, ensuring smooth sliding of the slider 230, guaranteeing smooth operation of the flip screen, and reducing noise.

[0032] It is conceivable that the slider 230 described above can also be slidably mounted on the base 110 in other ways. For example, the base 110 is provided with a guide rod, which passes through the slider 230 and is located on one side of the lead screw 220. Thus, the slider 230 can slide relative to the base 110 along the guide rod.

[0033] Reference Figure 1 and Figure 2According to some embodiments of this utility model, adapter blocks 310 are detachably mounted on opposite ends of the back of the display screen 300. The display screen 300 is rotatably connected to the corresponding slider 230 and the corresponding connecting rod 400 via the adapter blocks 310. The adapter blocks 310 can be made of a material with higher strength than the display screen 300, so that the adapter blocks 310 can withstand greater stress. Therefore, the force between the display screen 300 and the slider 230, and the force between the display screen 300 and the connecting rod 400, is first borne by the adapter blocks 310 and then distributed to the display screen 300, avoiding excessive local stress on the display screen 300 and better protecting the display screen 300.

[0034] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, each adapter block 310 is provided with a limiting groove 311, wherein one end of the connecting rod 400 is rotatably mounted in the corresponding limiting groove 311, and the connecting rod 400 and the side wall of the corresponding limiting groove 311 are used to cooperate and abut against each other to limit the rotation range of the display screen 300. Thus, when the display screen 300 rotates open relative to the base 110 to the maximum angle, the connecting rod 400 can abut against the side wall of the limiting groove, thereby limiting the display screen 300 from continuing to rotate and open.

[0035] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the adapter block 310 is detachably mounted on the display screen 300 by a plurality of bolts, and there is at least one set of mutually contacting surfaces between the adapter block 310 and the display screen 300, so as to transmit the force between the adapter block 310 and the display screen 300 more evenly and reduce stress concentration.

[0036] Reference Figure 2 and Figure 3 According to some embodiments of this utility model, the overload protection component 270 is elastic, has a mounting hole 271, and has multiple elastic protrusions 272 on its outer periphery. The output shaft of the electric drive device 210 is inserted into the mounting hole 271 and abuts against the inner wall of the mounting hole 271. The output synchronous wheel 250 is sleeved on the overload protection component 270 and abuts against the elastic protrusions 272. Thus, the overload protection component 270 can form a damping effect. Power is transmitted between the output shaft of the electric drive device 210 and the output synchronous wheel 250 using this damping effect. When the rotation of the display screen 300 is obstructed, the damping provided by the overload protection component 270 cannot provide the power required for the rotation of the output synchronous wheel 250. At this time, slippage occurs between the output shaft and the output synchronous wheel 250, thereby preventing overload of the electric drive device 210 and the display screen 300.

[0037] Reference Figure 2 and Figure 3According to some embodiments of the present invention, an overload protection member 270 is provided with a notch 273 on its outer periphery. The notch 273 is provided through the axial direction of the overload protection member 270 and is connected to the mounting hole 271.

[0038] Reference Figure 4 According to some embodiments of the present invention, the flip screen further includes a cover 120, which is located on the side of the base 110 facing the display screen 300. The cover 120 is installed on the base 110, and the drive mechanism 200 is disposed between the cover 120 and the base 110. The cover 120 has an avoidance opening 121 to avoid the display screen 300, thereby the drive mechanism 200 can be hidden by the cover 120.

[0039] Reference Figure 2 According to some embodiments of the present invention, the electric drive device 210 includes a motor 211 and a reducer 212. The motor 211 and the reducer 212 are connected in transmission. The output shaft of the electric drive device 210 is the output shaft of the reducer 212. The display screen 300 can be driven to rotate at a smooth speed by the high-speed motor 211.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
