The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0024] Example 1: Example 1 provides a spring-damped connection assembly, such as... Figure 1As shown, it includes: a hinge mounting base 1, a damping hinge 2, and a spring mounting base 3; the hinge mounting base 1 is used to connect the push-to-open display screen 4 structure; the damping hinge 2 includes a first hinge 21, a damping pivot 22, and a second hinge 23; one end of the first hinge 21 is connected to the hinge mounting base 1, and the other end of the first hinge 21 is rotatably connected to one end of the damping pivot 22; one end of the second hinge 23 is rotatably connected to the other end of the damping pivot 22; the other end of the damping hinge 2 is connected to the spring mounting base 3.

[0025] In one possible implementation, such as Figure 1 As shown, a first spring pad 24 is fitted onto the damping shaft 22, and the first spring pad 24 is in contact with the first hinge 21. A second spring pad (not shown) is fitted onto the damping shaft 22, and the second spring pad is in contact with the second hinge 23. The first spring pad 24 and the second spring pad are used to enhance the friction between the damping shaft 22 and the first hinge 21 and the second hinge 23, respectively. The spring pads not only increase static friction but also affect dynamic damping. When the screen is raised or lowered, the spring pads apply a certain resistance to the moving hinges, making the entire movement smoother and slower.

[0026] In one possible implementation, to enhance stability, such as Figure 1 The damping hinges 2 shown are provided in multiple configurations, and are connected by hinge connecting rods 25. One end of each damping hinge 2 is connected to a hinge mounting base 1, while the other end is connected to a spring mounting base 3. This multi-hinge design not only improves the overall structural strength but also allows for more even pressure distribution, reduces the load on individual hinges, and extends service life.

[0027] In one possible implementation, such as Figure 2 As shown, the spring mounting base 3 has a sliding hole 31; a positioning post 32 is provided in the sliding hole 31, and a limiting block 321 is sleeved on the positioning post 32; a spring 33 is provided in the sliding hole 31; the top of the spring 33 is connected to the limiting block 321; the bottom of the spring 33 is connected to the side wall of the sliding hole 31, and the top of the positioning post 32 is used to connect to the press-type display screen 4 structure.

[0028] like Figure 2 As shown, the size of the middle part of the sliding hole 31 is larger than the size of both ends of the sliding hole 31. The limiting block 321 is located in the middle of the sliding hole 31 and can move up and down within the middle space of the sliding hole 31.

[0029] Without external force, spring 33 is in its natural state. At this time, the limiting block 321 is positioned within the sliding hole 31, keeping the press-type display screen 4 at a preset height. When downward pressure is applied to the screen, the positioning post 32 moves the limiting block 321 downward within the sliding hole 31, compressing the spring 33. With continued pressing, the spring 33 continues to be compressed, storing elastic potential energy. During this process, the downward speed of the screen is effectively controlled by the resistance provided by the damping shaft 22, avoiding sudden rapid movement and ensuring smooth operation. When additional pressure is stopped and a certain pressing force is maintained, the screen remains in the new position.

[0030] Example 2: Example 2 provides a press-type display screen structure for connecting the above-mentioned spring-damped connection assembly; as follows: Figure 3 As shown, it includes a display screen 4 and a mounting base 5. The display screen 4 is connected to the mounting base, and the mounting base 5 is connected to the hinge mounting seat 1 and the positioning post 32.

[0031] In one possible implementation, such as Figure 3 As shown, it also includes a button circuit board 6, which is electrically connected to the display screen 4, and a capacitive touch button 7 is provided on the button circuit board 6.

[0032] In one possible implementation, such as Figure 4 and Figure 5 As shown, it also includes a housing 8, a fixing post 81, and an observation component 9. The spring damping connection component is located inside the housing 8. One end of the fixing post 81 is connected to the bottom of the housing 8, and the other end of the fixing post 81 is connected to the spring mounting seat 3. The observation component 9 includes tempered glass 91, a glass pressure ring 92, and an observation window 93. The tempered glass 91 is located between the glass pressure ring 92 and the observation window 93. The tempered glass 91 is attached to the display screen 4 and the capacitive touch button 7.

[0033] For reference, the inner wall of the observation window 93 is provided with internal threads, and the outer wall of the glass retaining ring 92 is provided with external threads. The observation window 93 is placed above the tempered glass 91, and then the glass retaining ring 92 is screwed into the observation window 93 from the bottom of the tempered glass 91. In this way, the glass retaining ring 92 and the observation window 93 clamp the tempered glass 91.

[0034] The top of the housing 8 is provided with an opening, and the top opening of the housing 8 is rotatably connected to the observation window 93.

[0035] For reference, the outer wall of the observation window 93 is provided with external threads, and the top opening of the housing 8 is provided with internal threads, and the observation window 93 and the top opening of the housing 8 are threadedly connected.

[0036] When the viewing window 93 is screwed into the top opening of the housing 8, the tempered glass 91 descends continuously, applying downward pressure to the display screen 4 and capacitive touch buttons 7. The display screen 4, capacitive touch buttons 7, and mounting base 5 descend, and the positioning post 32 drives the limiting block 321 to move downward within the sliding hole 31. The limiting block 321 compresses the spring 33, and with continued pressure, the spring 33 continues to be compressed, storing elastic potential energy. During this process, the descent speed of the screen is effectively controlled by the resistance provided by the damping shaft 22, avoiding sudden rapid movement and ensuring smooth operation. When the viewing window 93 is tightened, the display screen 4 remains in the new position; the tempered glass 91 remains in contact with the display screen 4 and capacitive touch buttons 7.

[0037] As the viewing window 93 is unscrewed from the top opening of the housing 8, the external threads on the outer wall of the viewing window 93 gradually separate from the internal threads at the top opening of the housing 8. As the viewing window 93 is unscrewed, the tempered glass 91 gradually rises, and the previously compressed spring 33 gradually returns to its original length. The spring 33 releases its stored energy, pushing the limit block 321 upwards. This upward thrust is transmitted to the mounting base 5 via the positioning post 32, and then acts on the display screen 4 and the capacitive touch button 7, causing them to slowly rise back to their initial positions. During the spring 33's reset process, the damping shaft 22 continues to provide appropriate resistance, ensuring a smooth rise of the screen and avoiding impacts caused by sudden rebound. When the viewing window 93 is fully unscrewed from the top opening of the housing 8, the tempered glass 91 has completely detached from the surfaces of the display screen 4 and the capacitive touch button 7, and there is no longer any direct contact between them. At this point, the display screen 4, the capacitive touch button 7, and the mounting base 5 have returned to their initial height under the action of the spring 33.

[0038] For example, the display screen 4 structure can be fully ejected from the housing 8 by the action of spring 33, stopping in an easily accessible position for user inspection, cleaning, or repair. Because the display screen 4 structure can eject from the housing 8, technicians can easily access all components behind the display screen 4, including but not limited to the button circuit board 6, capacitive touch buttons 7, and other connecting lines, simplifying the repair process.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
