DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 2 and Figure 3 As shown, combined with Figure 4 and Figure 5The present embodiment provides a display assembly, including a mounting base 1 and a display screen 2. The display screen 2 is connected to one side of the mounting base 1 in a flip-over manner so that the display screen 2 can be unfolded or folded relative to the mounting base 1. After unfolding, the display screen 2 can be flipped up and down. The mounting base 1 is provided with a receiving groove 3 for accommodating the folded display screen 2. The receiving groove 3 is provided with a contact switch 4. The contact switch 4 is electrically connected to the display screen main board 5. When the display screen 2 is folded into the receiving groove 3, the back of the display screen 2 triggers the contact switch 4, so that the content displayed on the display screen main board 5 is switched from reverse display to forward display; wherein the up, down, left, right, front, and back directions are represented by Figure 4 shall prevail.

[0028] The display assembly of this embodiment adds a contact switch 4 in the accommodating groove 3 for installing the display screen 2. Once the display screen 2 is folded into place, the contact switch 4 will send a trigger signal, which is transmitted to the display screen motherboard 5. The display screen motherboard 5 can automatically switch the reverse display content to the forward display. No manual operation is required, and it is automatically triggered by hardware, which is very convenient to use.

[0029] The contact switch 4 is positioned near the opening and closing side 6 of the display screen 2. The opening and closing side 6 is the side where the display screen 2 can be opened. In this embodiment, the opening and closing side 6 is located on the left side of the mounting base 1. This arrangement ensures that the display screen 2 switches its display direction only when it is properly installed in the receiving groove 3. This not only detects whether the display screen 2 is properly installed, but also reduces erroneous operations caused by accidentally touching the contact switch 4.

[0030] The contact switch 4 is a spring-loaded switch. A mounting hole 7 is defined within the receiving recess 3. The spring-loaded switch is mounted within the mounting base 1 and extends through the mounting hole 7 into the receiving recess 3. This spring-loaded switch utilizes existing technology and is based on the mechanical movement of a spring. It typically consists of a curved, elastic metal spring and a contact in contact with it. In its natural state, the spring and contact are separated, disconnecting the switch. When an external force bends the spring, the spring and contact close, closing the switch. This spring-loaded switch offers simpler installation and more reliable detection.

[0031] The display screen 2 further includes a detection board 9 disposed within the mounting base 1 , on which the contact switch 4 is mounted. The detection board 9 also includes a main control module electrically connected to the contact switch 4 . The main control module is electrically connected to the display screen mainboard 5 . The main control module detects the trigger signal of the contact switch 4 and sends a switching enable signal to the display screen mainboard 5 . The core component of the main control module is a single-chip microcomputer or a DSP, and the main control module can be configured using existing technology. By detecting the trigger signal of the contact switch 4 and transmitting it to the display screen mainboard 5 through the main control module, the structure of the display screen 2 does not need to be changed, making the display screen 2 more versatile.

[0032] The opening and closing side 6 of the accommodating groove 3 near the display screen 2 is provided with a finger avoidance position 11. In this embodiment, the finger avoidance position 11 is a C-shaped notch provided on the left side of the accommodating groove 3. This arrangement facilitates opening and closing the display screen 2 using the finger avoidance position 11.

[0033] A limiting slot 12 is provided on the side of the accommodating recess 3 facing away from the opening and closing side 6 of the display screen 2. A limiting block 14 is connected to a connection side 15 of the display screen 2. In this embodiment, the connection side 15 of the display screen 2 is located on the right side of the mounting base 1. First shafts 13 are connected to both ends of the limiting block 14. The limiting block 14 is connected to the limiting slot 12 by rotating left and right via the first shaft 13, thereby enabling the display screen 2 to flip left and right relative to the mounting base 1. This left-right flipping structure not only utilizes the limiting slot 12 to mount the first shaft 13 and the limiting block 14, resulting in a simple and compact structure, but also utilizes the limiting slot 12 to limit the axial position of the limiting block 14, allowing the limiting block 14 to stably rotate circumferentially within the limiting slot 12, thereby making left-right flipping of the display screen 2 more stable and reliable.

[0034] The connection side 15 of the display screen 2 is rotatably connected to the limiting block 14 via a second rotating shaft 16, allowing the display screen 2 to flip up and down around the second rotating shaft 16. The second rotating shaft 16 is perpendicular to the first rotating shaft 13 and coincides with the central axis of the display screen 2. This arrangement utilizes a simple rotating shaft structure to achieve the upside-down flipping of the display screen 2.

[0035] Example 2:

[0036] like Figure 4 and Figure 5 As shown, combined with Figure 2 and Figure 3 This embodiment provides a high-definition camera, which includes a base 17 and a support rod 18 arranged on the base 17. The support rod 18 is also provided with the display component 8 in Example 1, and the mounting base 1 of the display component 8 is integrally formed with the support rod 18; in this embodiment, the display component 8 is arranged in the middle of the support rod 18, and the top of the support rod 18 is also provided with a camera component 10. The support rod 18 includes a vertical rod 19 arranged on the base 17 and a horizontal rod 20 arranged at the top of the vertical rod 19. The display component 8 is arranged in the middle of the vertical rod 19, and the camera component 10 is arranged on the horizontal rod 20.

[0037] The working principle of the high-speed scanner in this embodiment is as follows:

[0038] When stored, the display screen 2 is folded into the receiving groove 3 of the mounting base 1, with the back of the display screen 2 facing the user, so that the screen of the display screen 2 can be protected;

[0039] When in use, the display screen 2 is flipped rightward to be fully unfolded, with the front of the display screen 2 facing the user and displaying in the forward direction. At this time, the user can clearly see the content on the display screen 2. This is the first usage state of the display screen 2. In this state, the angle of the display screen 2 can be adjusted by rotating the display screen 2 up and down to improve the display effect. In this state, the angle of rotation is small, and the upper and lower positions of the display screen 2 will not be reversed, thereby preventing reverse display.

[0040] The second usage state is that when the display screen 2 is unfolded, the display screen 2 is flipped up and down so that its back faces the user, and then the display screen 2 is flipped to the left. At this time, the display screen 2 is folded and the front faces the user, but the up and down positions of the display screen 2 are reversed, so that the content displayed on the display screen 2 is reversed. However, when the display screen 2 is folded into place, the back of the display screen 2 will press the contact switch 4 in the accommodating groove 3, and the contact switch 4 is triggered. After the main control module on the detection board 9 detects the trigger signal of the contact switch 4, it will send a switching enable signal to the display screen main board 5. After receiving the switching enable signal, the display screen main board 5 will automatically switch the reverse displayed content to forward display. The whole process is triggered by hardware and does not require manual operation.
