Description

Technical Field

[0001] This utility model relates to the field of laptop computer accessories, specifically a hinge mechanism for laptop computers. Background Technology

[0002] Existing laptop hinges typically have annular oil guide grooves directly on the hinge pivot, and the hinge is made of zinc alloy. This design has the following disadvantages: Laptop hinges with this structure have slow heat dissipation, which can lead to localized overheating and cause the lubricating oil in the oil groove to melt easily. This requires the lubricating oil in the oil groove to have a high melting point. The annular oil guide grooves on the pivot are not conducive to lubricating oil storage, which may lead to oil leakage when opening and closing the laptop lid. At the same time, the annular oil guide grooves on the pivot are not easy to form a uniform oil film.

[0003] To solve the above problems, after searching, Chinese Patent No. CN207246219U was found, which discloses a hinge mechanism for a laptop computer. The mechanism includes a rotating bracket, a stop block, a shaft core rod, several loose fin rings and several tight fin rings. The rotating bracket further includes a support part, a first bushing and a second bushing, with the first bushing located at one end of the lower end face of the rotating bracket.

[0004] Although the above-mentioned device can control the fluctuation range of torque and friction within 7% and improve lubrication, in actual use, when the laptop screen is opened, excessive force is often applied. This can cause pressure to continue to be applied to the screen even when it is opened to its maximum angle, making the damping mechanism inside the hinge prone to deformation or breakage. Utility Model Content

[0005] The purpose of this invention is to provide a hinge mechanism for a laptop computer to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, a hinge mechanism for a laptop computer is provided, comprising an LCD support and a spindle. A connecting seat is fixed to the end of the LCD support, and a stop plate is provided on one side of the connecting seat. Meanwhile, a base support B is provided on the other side of the connecting seat. A stop plate and a spindle are installed between the base support B and the base support A. Locking plates are provided at the ends of both the base support A and the base support B.

[0007] Furthermore, the foundation support frame A and foundation support frame B are symmetrical about the central axis of the stop plate, and both foundation support frame A and foundation support frame B are provided with torsion plates.

[0008] Furthermore, the shaft is T-shaped, and its two ends pass through the base support A and the base support B respectively and are connected to the locking plate; the end of the connecting seat is fixed with a docking seat.

[0009] Furthermore, the tail end of the shaft covers the mating seat and is fixed by two sets of bolts, and the mating seat is provided with two sets of positioning pins arranged diagonally, and the shaft is provided with two sets of positioning holes arranged diagonally.

[0010] Furthermore, the dimensions of the positioning post and the positioning hole are matched, and the positioning post is inserted into the positioning hole.

[0011] Furthermore, both the foundation support A and the foundation support B are provided with a mounting bracket at their ends, and a mounting space is formed between the two sets of mounting brackets. At the same time, a stop plate is provided inside the mounting space.

[0012] Furthermore, a limiting strip is provided on one side of the stop plate, and a limiting groove is provided on the card holder. The size of the limiting groove and the limiting strip are matched, and the limiting strip is inserted into the inside of the limiting groove. A buffer plate is provided on the other side of the stop plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This solution utilizes a robust hard-limiting mechanism comprised of a stop plate, a limiting strip, and a limiting groove on the mounting bracket. Even when the user continues to apply pressure to the screen at its maximum angle, the rigid mechanical interference between the limiting strip and the sidewall of the limiting groove directly transmits excessive rotational force through the mounting bracket to the stable, symmetrical support structure of base frame A and base frame B. This effectively prevents further pressure transmission to the core damping components, avoiding torsional deformation of the axis and plastic deformation or breakage of the torsion plate.

[0015] The buffer plate on the other side of the stop plate can absorb some of the impact energy at the moment of extreme collision, further protecting the entire shaft system and significantly improving its reliability and service life in terms of resistance to misuse and impact.

Detailed Implementation

[0025] Please see Figures 1-8 This utility model provides a hinge mechanism for a laptop computer, including an LCD support 1 and a spindle 5. A connecting seat 11 is fixed to the end of the LCD support 1, and a stop plate 2 is provided on one side of the connecting seat 11. Meanwhile, a base support B31 is provided on the other side of the connecting seat 11. The stop plate 2 and the spindle 5 are installed between the base support B31 and the base support A3. Locking plates 4 are provided at the ends of both the base support A3 and the base support B31.

[0026] The foundation support frame A3 and the foundation support frame B31 are symmetrical about the central axis of the stop plate 2, and both the foundation support frame A3 and the foundation support frame B31 are equipped with torsion plates 32.

[0027] The shaft 5 is T-shaped, and its two ends pass through the foundation support A3 and the foundation support B31 respectively and are connected to the locking plate 4; the end of the connecting seat 11 is fixed with the docking seat 12.

[0028] The tail end of the shaft 5 covers the docking seat 12 and is fixed by two sets of bolts 6. The docking seat 12 is provided with two sets of positioning posts 13 arranged diagonally, and the shaft 5 is provided with two sets of positioning holes 14 arranged diagonally.

[0029] The positioning pin 13 and the positioning hole 14 are matched in size, and the positioning pin 13 is inserted into the positioning hole 14.

[0030] Both the foundation support A3 and the foundation support B31 are provided with a mounting bracket 33 at their ends, and a mounting space 34 is formed between the two sets of mounting brackets 33. At the same time, a stop piece 2 is provided inside the mounting space 34.

[0031] Working principle: When the LCD screen rotates around the axis 5, the connecting seat 11 fixed to the LCD support 1 rotates accordingly, and drives the docking seat 12 on it to move synchronously. The docking seat 12 is rigidly connected to the tail end of the axis 5 through the positioning post 13 inserted into the positioning hole 14 and the bolt 6, thereby transmitting the rotational torque to the axis 5. At the same time, the two ends of the axis 5 pass through the base support A3 and the base support B31 respectively and are connected to the locking plate 4. The torsion plate 32 on it provides a constant frictional damping force for the rotation of the axis 5, so as to realize the stable suspension of the screen at any angle. When the screen is opened or closed to the limit angle, the inner wall of the connecting seat 11 and the stop plate 2 mechanically interfere, thereby effectively preventing the screen from rotating excessively, playing the role of rigid limit and protecting the internal cables.

[0032] The symmetrically distributed base support and torsion plate 32 provide balanced and stable rotational damping and support strength; the cooperation of positioning column 13 and positioning hole 14 ensures the precise alignment and connection strength of the shaft 5 installation and prevents loosening; the hard limiting structure of stop plate 2 and connecting seat 11 reliably limits the rotation range of the screen and avoids damage caused by excessive opening and closing. The overall structure is compact, the assembly relationship is clear, and the reliability is high.

[0033] The robust hard limiting mechanism formed by the stop plate 2, the limiting strip 21, and the limiting groove 331 on the card holder 33 can effectively prevent the excessive rotational force from being transmitted directly to the stable symmetrical support structure of the base frame A3 and the base frame B31 through the rigid mechanical interference of the side wall of the limiting strip 21 and the limiting groove 331, even when the user continues to apply pressure to the screen which has been opened to its maximum angle. This is achieved by the rigid mechanical interference of the side wall of the limiting strip 21 and the limiting groove 331. The pressure is then effectively transmitted to the core damping component, namely the friction damping mechanism composed of the shaft 5 and the torsion plate 32, which prevents the shaft 5 from torsional deformation and the torsion plate 32 from plastic deformation or breakage. At the same time, the buffer plate 20 on the other side of the stop plate 2 can absorb part of the impact energy at the moment of extreme collision, further protecting the entire rotating shaft system and significantly improving its reliability and service life in terms of resistance to misuse and impact.

[0034] As a preferred embodiment, a limiting strip 21 is provided on one side of the stop plate 2, and a limiting groove 331 is provided on the card holder 33. The size of the limiting groove 331 and the limiting strip 21 are matched, and the limiting strip 21 is inserted into the inside of the limiting groove 331. A buffer plate 20 is provided on the other side of the stop plate 2.

[0035] like Figures 7-8 As shown: By adding a limiting strip 21 that cooperates with the upper limit groove 331 of the card holder 33, the positioning accuracy and structural stability of the stop plate 2 in the mounting space 34 of the card holder 33 are greatly enhanced, effectively preventing the stop plate 2 from shifting or shaking during long-term use, thereby ensuring the absolute reliability and consistency of the limiting action.

[0036] Meanwhile, the buffer plate 20 provided on the other side of the stop plate 2 can provide effective buffering and energy absorption for collisions between the stop plate 2 and the connecting seat 11 or other adjacent components when the screen is opened to the limit angle, significantly reducing impact noise and instantaneous stress, effectively protecting the stop plate 2 and its associated components, avoiding wear or deformation caused by hard contact, thereby improving the durability of the entire pivot system and the quietness during use.
