Description

Technical Field

[0001] This utility model belongs to the field of electronic product accessories, specifically relating to a laptop hinge structure. Background Technology

[0002] A laptop computer typically includes a base and a display module that is rotatably connected to the base via a hinge structure. The laptop computer can be opened or closed by flipping the display module up and down.

[0003] However, in actual use, when existing laptops are opened and used, if the force that drives the display module to continue to increase the angle of rotation relative to the base continues to increase, the screen can easily cause the base to tilt upwards, which seriously reduces the user experience. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved laptop hinge structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A laptop hinge structure is disclosed. The laptop includes a base that rests flat on a table and a display screen. The hinge structure includes a pivot that is horizontally and fixedly mounted on the base and an auxiliary back plate. The display screen has a rotating connection end that is rotatably connected to the pivot. The auxiliary back plate is rotatably connected to the pivot and / or the rotating connection end. As the display screen opens relative to the base, the auxiliary back plate rotates synchronously around a horizontal axis. When the display screen is opened to its maximum angle, the auxiliary back plate abuts against the table, and the display screen is located between the auxiliary back plate and the base.

[0007] Preferably, when the display screen is opened to its maximum angle, the bottom surface of the auxiliary back plate is flush with the bottom surface of the base. In this configuration, the auxiliary back plate provides good support, which helps enhance the overall stability of the device when the display screen is open.

[0008] Preferably, the back of the display screen forms a receiving groove that matches the auxiliary back panel. When the display screen is closed relative to the base, the auxiliary back panel folds down and is located within the receiving groove. Here, when the laptop is folded, the auxiliary back panel can be concealed within the receiving groove, facilitating storage and improving aesthetics.

[0009] Specifically, there are two rotating shafts arranged side by side with intervals, two rotating connection ends connected to the two rotating shafts one to one, a receiving groove located between the two rotating connection ends, and an auxiliary back plate rotatably connected between the two rotating connection ends from opposite sides.

[0010] Preferably, the display screen is rotatably mounted on the rotating connection end around the center line of the rotating shaft; the auxiliary back plate is rotatably connected to the rotating shaft and / or the rotating connection end via a pivot and rotates around the center line of the pivot.

[0011] Preferably, a insertion groove is formed on one side of the end face of the rotating shaft, which matches one end of the pivot; the interior of the rotating connection end is hollow and equipped with a transmission component. The pivot passes through the rotating connection end and is inserted into the insertion groove from one end. As the rotating connection end rotates around the center line of the rotating shaft, the transmission component drives the pivot and synchronously drives the auxiliary back plate to rotate around the center line of the pivot. Here, the rotation of the auxiliary back plate can be synchronously driven as the display screen flips, resulting in a simple, reliable, and easy-to-operate structure.

[0012] Specifically, the transmission component includes internal teeth disposed on the inner wall of the rotating connection end and distributed around the center line of the rotating shaft, and external teeth disposed on the outer wall of the pivot and meshing with the internal teeth.

[0013] Preferably, arc-shaped clearance grooves are formed on opposite sides of the rotating connection end, through which the pivot passes and moves relative to the pivot along the clearance groove as the rotating connection end rotates. This forms a motion guide, improving the stability of the display screen's movement.

[0014] Preferably, in the orthographic projection of the pivot along its axial direction, the corresponding ends of the pivot form connected arc segments and straight segments, and the auxiliary back plate has a connecting groove that matches the corresponding ends of the pivot. This ensures that the auxiliary back plate rotates synchronously with the pivot.

[0015] Furthermore, the display screen's rotation angle is 0° to 90°; the auxiliary back panel's rotation angle is 0° to 180°. In this application, the angle at which the auxiliary back panel rotates with the display screen can be adjusted by adjusting the gear ratio of the transmission component, as needed.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] When existing laptops are opened for use, if the force driving the display module to continue increasing its rotation angle relative to the base can easily cause the screen to tilt upwards, severely degrading the user experience. This application addresses this issue by redesigning the laptop hinge structure as a whole, cleverly resolving the shortcomings and defects of existing technologies. With this new hinge mechanism, when the laptop is opened, as the display rotates around the pivot on the base, the auxiliary backplate rotates synchronously around the horizontal axis. When the display reaches its maximum angle relative to the base, the auxiliary backplate and base simultaneously abut against the surface, with the display positioned between them. This synchronous support from the auxiliary backplate and base prevents the display from tilting upwards due to force. Therefore, compared to existing technologies, this invention, on the one hand, effectively prevents the display from tilting upwards by opening and closing the auxiliary backplate with the movement of the display, and on the other hand, its simple structure allows the auxiliary backplate to unfold synchronously with the opening of the display, making it easy to operate.

[0032] like Figures 1 to 5 As shown, the laptop computer in this embodiment includes a base A that is placed flat on a table and a display screen B. The laptop computer hinge structure in this embodiment includes a hinge 1 and an auxiliary back plate 2.

[0033] Specifically, the rotating shaft 1 extends horizontally and is fixedly mounted on one side of the base A; the display screen B has a rotating connection end B0 that is rotatably connected to the rotating shaft 1.

[0034] For ease of implementation, there are two rotating shafts 1 arranged side by side at intervals along their own axial direction, and there are two rotating connection ends B0 that are sleeved and rotatably connected to the two rotating shafts 1 in a one-to-one correspondence.

[0035] In this example, the auxiliary back plate 2 is rotatably connected to the rotating shaft 1 and / or the rotating connection end B0. As the display screen B opens relative to the base A, the auxiliary back plate 2 rotates synchronously around the horizontal axis. When the display screen opens to the maximum angle, the auxiliary back plate 2 simultaneously abuts against the table surface, and the display screen B is located between the auxiliary back plate 2 and the base A.

[0036] In some specific embodiments, the display screen B is rotatably mounted on the rotating connection end B0 around the center line of the rotating shaft 1; the auxiliary back plate 2 is rotatably connected to the rotating shaft 1 and / or the rotating connection end B0 via a pivot s and rotates around the center line of the pivot s. A insertion groove 10 is formed on the end face of the rotating shaft 1, located on one side and matching one end of the pivot s; the rotating connection end B0 is hollow and equipped with a transmission member d. The pivot s passes through the rotating connection end B0 and is inserted into the insertion groove 10 from one end. As the rotating connection end B0 rotates around the center line of the rotating shaft 1, the transmission member d drives the pivot s and synchronously drives the auxiliary back plate 2 to rotate around the center line of the pivot s. Here, the rotation of the auxiliary back plate can be synchronously driven as the display screen flips, resulting in a simple, reliable, and easy-to-operate structure.

[0037] To further facilitate implementation, the transmission component d includes internal teeth d0 disposed on the inner wall of the rotating connection end B0 and distributed around the center line of the rotating shaft 1, and external teeth d1 disposed on the outer wall of the pivot s and meshing with the internal teeth d0. The angle at which the auxiliary backplate rotates with the display screen can be adjusted by changing the gear ratio of the transmission component as needed. In this application, the rotation angle of the display screen is 0° to 90°; the rotation angle of the auxiliary backplate is 0° to 180°. That is, when the rotation angle of the display screen is 0°, the rotation angle of the auxiliary backplate is also 0°, and both are folded relative to the base; when the rotation angle of the display screen is 90°, the rotation angle of the auxiliary backplate is 180°.

[0038] Meanwhile, arc-shaped clearance grooves c0 are formed on both sides of the rotating connection end B0. The pivot s passes through the clearance grooves c0, and as the rotating connection end B0 rotates, the pivot s moves relative to the clearance grooves c0 based on the transmission engagement of the internal teeth d0 and the external teeth d1. This forms a motion guide, improving the stability of the display screen's movement.

[0039] In the orthographic projection along the axial direction of the pivot s, the corresponding ends of the pivot s form connected arc segments s0 and straight segments s1. The auxiliary back plate 2 has a connecting groove 20 that matches the corresponding ends of the pivot s, and the pivot s is inserted into the connecting groove 20 from the corresponding ends. Here, it is ensured that the auxiliary back plate rotates synchronously with the pivot.

[0040] To further facilitate implementation, when display screen B is opened to its maximum angle, the bottom surface of the auxiliary backplate 2 is flush with the bottom surface of the base A. Here, the auxiliary backplate provides good support, which helps enhance the overall stability of the device when the display screen is open.

[0041] Furthermore, the back of the display screen B forms a receiving groove c1 that matches the auxiliary back plate 2. The receiving groove c1 is located between two rotating connection ends B0, and the auxiliary back plate 2 is rotatably connected between the two rotating connection ends B0 from opposite sides. When the display screen B is closed relative to the base A, the auxiliary back plate folds down and is located within the receiving groove c1. Here, when the laptop is folded, the auxiliary back plate can be hidden inside the receiving groove, which facilitates storage and improves aesthetics.

[0042] In summary, with this laptop hinge mechanism, when the laptop is opened, as the display screen rotates around the hinge on the base, the auxiliary back plate rotates synchronously around the horizontal axis. When the display screen is opened to its maximum angle relative to the base, the auxiliary back plate and the base simultaneously abut against the table surface, and the display screen is located between the auxiliary back plate and the base. Thus, with the synchronous abutment of the auxiliary back plate and the base, the display screen is prevented from being forced to lift the base. Therefore, compared with the prior art, this utility model has the following advantages: First, the auxiliary back panel opens or closes with the movement of the display screen. When the display screen is open, the auxiliary back panel and the base simultaneously support the table surface, effectively preventing the display screen from causing the base to tilt upwards due to force, thus greatly improving the user experience. Second, the structure is simple and the auxiliary back panel can be unfolded synchronously with the opening of the display screen, making it easy to operate. Third, when the laptop is folded, the auxiliary back panel can be hidden in the receiving slot, making it easy to store and improving the aesthetics. Fourth, the auxiliary back panel can be rotated synchronously with the flipping of the display screen, making the structure simple, reliable, and easy to operate. Fifth, in this application, the angle of the auxiliary back panel as the display screen flips can be adjusted by adjusting the gear ratio of the transmission component as needed.

[0043] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
