Description

Technical Field

[0001] This utility model relates to the field of notebook structural design, and in particular to a support hinge device for a notebook screen shell. Background Technology

[0002] Laptop screen designs typically consider various usage scenarios, including flip and tablet modes. Early laptops primarily used a single hinge to connect the screen to the keyboard base. After prolonged use, this hinge could wear down, causing the screen to wobble and affecting visual experience and work efficiency. Furthermore, the hinge structure limited the screen's opening angle, failing to meet users' personalized needs in different scenarios. Most modern laptops, especially those with touchscreens, are equipped with hinge designs that can withstand a certain angle of rotation. These hinges are specially designed to maintain screen stability while allowing the screen to flip.

[0003] However, if your existing laptop screen casing frequently encounters the following problems during use:

[0004] Excessive screen flipping or use outside of its intended purpose can damage the screen's support structure. Prolonged use at abnormal angles puts stress on the hinges and screen frame, affecting their durability and reliability. Furthermore, accidental contact or even minor impacts after the screen has been flipped can cause it to tilt and flip, increasing wear on the hinges and negatively impacting the user and viewing experience. Utility Model Content

[0005] The main purpose of this utility model is to provide a support hinge device for a laptop screen casing, so as to effectively solve the safety hazard problem mentioned in the background art, where the opening of the existing traditional electroplating tank is always open.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A support hinge device for a laptop screen housing, comprising:

[0008] The main screen housing has a hinge at its bottom;

[0009] Two hinges are provided, and the two hinges are distributed at both ends of the bottom surface of the main screen housing;

[0010] A screen panel, which is mounted on the main screen housing;

[0011] A first flip shell, the first flip shell being located in the extending direction below the screen panel;

[0012] The second flip shell has one end movably mounted laterally to the bottom of the first flip shell;

[0013] A fixing hole is provided above the connection point between the first flip shell and the second flip shell;

[0014] The pressing and flipping component is movably connected to the inner walls of the two sides of the second flipping shell.

[0015] Also includes:

[0016] The first connection port is located on both sides of the second flip shell;

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1-3As shown, a supporting hinge device for a laptop screen housing includes: a main screen housing 1, a hinge 2, a screen panel 3, a first flip shell 4, a second flip shell 5, a fixing hole 6, and a pressing flip component 7. The main screen housing 1 has a hinge 2 at its bottom; there are two hinges 2, distributed at both ends of the bottom surface of the main screen housing 1. The screen panel 3 is mounted on the main screen housing 1. The first flip shell 4 extends below the screen panel 3; it is fixedly connected to the main screen housing 1. The first flip shell 4 and the second flip shell 5 are perpendicular to each other, located below the screen panel 3 and fixedly connected to the main screen housing 1. The base for flipping the screen housing is perpendicular to the second flip shell 5, providing support and guidance for the flipping of the screen housing.

[0036] Preferably, one end of the second flip shell 5 is laterally movably mounted to the bottom of the first flip shell 4, cooperating with the first flip shell 4 to achieve the flipping and fixing of the screen shell. A fixing hole 6 is opened above the connection between the first flip shell 4 and the second flip shell 5. The fixing hole 6 is used to lock the first pivot rod 11 when the screen shell is closed, ensuring structural stability. The locking opening 10, when the screen shell is open, restricts the movement of the first pivot rod 11 by increasing the opening, thereby fixing the position of the screen shell and preventing accidental closure. The two sides of the pressing flip member 7 are movably connected to the inner walls of the two sides of the second flip shell 5. The pressing flip member 7 is sleeved on the rod body of the first pivot rod 11 and the second pivot rod 12.

[0037] In this embodiment, as Figure 3 As shown, the first connection port 8 is located on both sides of the second flip shell 5, and the second connection port 9 is located on one side of the first connection port 8. Both the first connection port 8 and the second connection port 9 are strip-shaped openings. The design of the strip-shaped openings allows the first pivot rod 11 and the second pivot rod 12 to slide within them, thereby realizing the flipping and fixing functions of the screen shell. The locking port 10 is located on the first flip shell 4. The opening of the fixing hole 6 is smaller than that of the locking port 10. The two ends of the first pivot rod 11 pass through the first connection port 8, and the two ends of the first pivot rod 11 are embedded in the locking port 10. The opening of the locking port 10 is relatively large. Once the two ends of the first pivot rod 11 slide in, the two ends of the first pivot rod 11 will block the flipping space of the first flip shell 4, thereby preventing the main screen shell 1 from being flipped in a fixed position.

[0038] Preferably, both ends of the second pivot rod 12 pass through the two sides of the pressing and flipping member 7, and both ends of the second pivot rod 12 pass through the second connecting port 9. One end of the spring 13 is connected to the second flipping shell 5, and the other end of the spring 13 is connected to the first pivot rod 11. This provides elastic support and cushioning, making the flipping process smoother. At the same time, when the screen shell is closed, the tension of the spring 13 provides flipping space for the first flipping shell 4.

[0039] When closing the screen housing, manually press the flip component 7. Pressing the flip component 7 will cause the two ends of the first pivot rod 11 and the second pivot rod 12 to slide in the first connection port 8 and the second connection port 9 respectively. The spring 13 is stretched, making room for the first flip shell 4 to flip. The main screen housing 1, which is no longer blocked by the first pivot rod 11, can be closed by manually flipping it downwards.

[0040] It should be noted that the supporting hinge device for a laptop screen housing designed in this utility model is used by assembling this utility model onto the keyboard housing, that is, connecting the second flip shell 5 to the keyboard housing. When the screen housing is in the normally closed state, the two ends of the first pivot rod 11 are embedded in the fixing holes 6. When the main screen housing 1 is manually flipped, the first flip housing 4 is driven to start flipping upwards around the connection between the first flip housing 4 and the second flip housing 5. The two ends of the first pivot rod 11 are pushed out of the fixing hole 6 by the bottom of the flipping first flip housing 4. During the pushing process, the spring 13 will be pulled, and the two ends of the first pivot rod 11 will move in the first connection port 8 to create space for the pushing process. When the two ends of the first pivot rod 11 slide into the locking port 10 along the bottom of the first flip housing 4, the large opening of the locking port 10 will block the flipping space of the first flip housing 4, thus preventing the main screen housing 1 from being flipped. After flipping, the main screen housing 1 is kept in the flipped upright position due to the limiting support of the locking port 10 and the first pivot rod 11. There is no need to worry about the screen not being able to maintain its upright position due to excessive flipping angle or wear at the hinge.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
