Description

Technical Field

[0001] This utility model relates to the field of hardware structure technology of laptop computers, and in particular to a laptop hinge that prevents the laptop from falling off. Background Technology

[0002] Currently, in existing technology, the hinge, or joint, is a crucial component connecting the display screen to the main body of a laptop, and its performance directly affects the user experience and lifespan of the laptop. Existing laptop hinges are typically secured to the laptop's base and screen casing using screws or other fasteners. However, during prolonged and frequent opening and closing, the hinge is subjected to continuous torque and vibration, which can easily cause the screws securing the hinge to loosen, or even cause the connection between the hinge and the laptop casing to detach or break. This not only affects the opening angle and stability of the screen, but in severe cases, it can lead to complete hinge failure, rendering the display unsecured.

[0003] Furthermore, in pursuit of a thinner and lighter design, some hinge structures suffer from insufficient structural strength in the fixing parts connecting them to the outer casing, further increasing the risk of detachment. Therefore, there is an urgent need for a simple, reliable solution that can fundamentally prevent hinge detachment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a non-detachable laptop hinge. Through structural innovation, it achieves a more secure connection between the hinge and the laptop shell, effectively preventing loosening and detachment under long-term use.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A non-detachable laptop hinge for connecting the main body of a laptop and a display module includes a fixed frame and a rotating frame that are coaxially arranged and rotate with each other. The fixed frame is used to connect to the shell of the laptop main body. The fixing frame is provided with at least one anti-detachment buckle structure, the anti-detachment buckle structure including a flexible buckle arm and a hook provided at the end of the buckle arm; The laptop host unit has a corresponding latching part inside its housing. When the mounting bracket is installed inside the laptop host unit's housing, the latching arm can elastically deform to engage the latch with the latching part inside the housing.

[0006] Furthermore, a hollow area is formed between the buckle arm and the fixing frame body to provide space for elastic deformation.

[0007] Furthermore, the anti-detachment buckle structure extends to one side from the base of the fixing frame and is stamped.

[0008] Furthermore, the snap-fit ​​part is a flange on the inner wall of the housing, a groove on the reinforcing rib, or a snap-fit ​​opening.

[0009] Furthermore, the fixing frame is provided with two anti-detachment buckle structures, and the two anti-detachment buckle structures are arranged symmetrically.

[0010] Furthermore, the end of the hook is formed into a guide slope for easy installation.

[0011] Furthermore, the rotating frame and the fixed frame are pivotally assembled.

[0012] Furthermore, the rotating frame and the fixed frame are also provided with a friction plate assembly sleeved on the pivot, which is used to provide rotational damping.

[0013] Furthermore, screw mounting holes are provided on the rotating frame and the fixed frame.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects: 1. This utility model adopts a double-fixing mechanism, which is reliable in preventing loosening. On the basis of traditional screw fastening, a mechanical buckle locking structure is added to form a double-fixing mechanism. Even if the screws loosen due to vibration or other reasons, the buckle structure can effectively prevent the shaft from falling off the housing, which greatly improves the reliability of the connection.

[0015] 2. This utility model has a simple structure and low cost. The anti-detachment buckle structure can be directly formed on the fixing frame by stamping and other processes, without the need to add extra parts. It is easy to process and manufacture, and the cost increase is minimal.

[0016] 3. This utility model is easy to install. The buckle structure has a built-in guide slope. When installing the rotating shaft, simply press it into the predetermined position of the housing, and the buckle will automatically engage. The installation process is simple and quick.

[0017] 4. This utility model enhances the overall structural strength. The symmetrically distributed snap-fit ​​structure can more evenly transmit the force on the hinge to the laptop shell, reducing local stress concentration, thereby improving the overall structural strength and service life of the laptop.

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] like Figure 1-5 As shown in Embodiment 1, an anti-detachment laptop hinge is provided for connecting the main body of a laptop and the display module. It mainly consists of a fixed frame 1 and a rotating frame 2, which are coaxially arranged and rotate with each other. The fixed frame 1 is used to connect to the casing 5 of the laptop main body, and the rotating frame 2 is used to connect to the display module. Screw mounting holes 6 are provided on both the rotating frame 2 and the fixed frame 1 for mounting and fixing to the laptop. At least one anti-detachment latching structure 4 is provided on the fixed frame 1. The anti-detachment latching structure 4 specifically includes a flexible latching arm 41 and a hook 42 located at the end of the latching arm 41.

[0027] To ensure stable assembly, two anti-detachment buckle structures 4 are symmetrically arranged in this embodiment. The anti-detachment buckle structure 4 extends to one side from the base of the fixing frame 1 and is stamped and formed, that is, two buckle arms 41 are extended and formed, and each buckle arm 41 has a hook 42 bent at the end.

[0028] In order to be assembled and snapped into the laptop casing 5, a snap-fit ​​part 51 corresponding to the snap hook 42 is provided inside the casing 5 of the laptop host part. When the fixing bracket 1 is installed inside the casing 5 of the laptop host part, the snap-fit ​​arm 41 can undergo elastic deformation so that the snap hook 42 and the snap-fit ​​part 51 inside the casing 5 engage with each other.

[0029] To ensure the elasticity of the latching arm 41, a hollow area 43 is formed between the latching arm 41 and the main body of the fixing frame 1 in this embodiment to provide space for elastic deformation. To facilitate the insertion of the hook 42, a guide slope 421 is formed at the end of the hook 42 for easy installation.

[0030] Specifically, in this embodiment, the rotating frame 2 and the fixed frame 1 are rotatably assembled via a pivot 3. Inside the rotating frame 2 and the fixed frame 1, there is also a friction plate assembly sleeved on the pivot 3, which is used to provide rotational damping.

[0031] refer to Figure 1-5 As shown in Embodiment 2, an anti-drop laptop hinge is provided, which mainly includes a fixed frame 1 and a rotating frame 2. The fixed frame 1 is fixed to the main body housing 5 of the laptop by screws passing through screw mounting holes 6, and the rotating frame 2 is fixed to the display screen housing of the laptop. The fixed frame 1 and the rotating frame 2 are rotatably connected by a pivot 3, and have built-in friction plate assembly 7 to provide stable opening and closing damping.

[0032] The core improvement of this invention lies in the symmetrical, integrally formed anti-detachment buckle structures 4 on both sides of the fixing frame 1. Each anti-detachment buckle structure 4 includes an elastic buckle arm 41 extending from the base of the fixing frame 1, with the end of the buckle arm 41 bent inward to form a hook 42. An elliptical hollow area 43 is formed between the buckle arm 41 and the fixing frame 1 body through a stamping process, which provides space for the buckle arm 41 to undergo elastic deformation under force. The end of the hook 42 is machined with a guide bevel 421.

[0033] Inside the casing 5 of the laptop main unit, a locking part 51 is pre-installed corresponding to the position of each anti-detachment latch structure 4. In this embodiment, the locking part 51 is a groove on the reinforcing rib inside the casing.

[0034] During installation, first align the fixing bracket 1 of the rotating shaft with the predetermined installation position on the housing 5. Then apply pressure to move the fixing bracket 1 into the housing 5. At this time, the guide slope 421 of the hook 42 first contacts the inner wall or reinforcing rib of the housing 5. Under continuous pressure, the latching arm 41 is squeezed and deforms outward toward the hollow area 43 using its elasticity, allowing the hook 42 to slide smoothly through the internal structure of the housing 5. When the fixing bracket 1 is fully pushed into place and its screw mounting hole 6 aligns with the screw hole on the housing, the hook 42 also moves to the position corresponding to the groove of the locking part 51. At this time, the elastic restoring force of the latching arm 41 drives the hook 42 to quickly spring back inward and lock into the groove of the locking part 51, forming a mechanical interlock. Finally, use screws to pass through the screw mounting hole 6 to finally tighten the rotating shaft.

[0035] With the above structure, even if the fixing screws become loose after long-term use, the hinge fixing bracket 1 cannot be removed from the housing 5 due to the presence of the anti-detachment buckle structure 4, thus ensuring that the hinge is always firmly connected to the laptop body and effectively avoiding laptop malfunctions caused by the hinge falling off.
