Description
Technical Field
[0001] This utility model belongs to the field of electronic product accessories, and specifically relates to a hinge structure suitable for laptops. Background Technology
[0002] Currently, existing laptops generally include a base and a screen module that is rotatably connected to the base via a hinge structure. The hinge structure generally includes a hinge and a torsion component (such as a spring, a bezel, etc.). The laptop is opened or closed by flipping the screen module up and down.
[0003] However, in actual use, existing laptops have the following technical defects:
[0004] 1. When the screen is turned on and put into use, if it is subjected to a force that causes the screen module to rotate at an angle that continues to increase relative to the base, the screen may easily cause the base to tilt upwards, which will seriously reduce the user experience.
[0005] 2. Using conventional torque components, excessive torque design will affect the opening and closing feel; insufficient torque design will easily lead to insufficient torque, causing the screen to wobble or poor closure between the screen and the base when it is in the open or closed limit position (there is a gap between the screen and the base). Summary of the Invention
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved hinge structure suitable for laptops.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A hinge structure for a laptop computer includes a screen and a base. The hinge structure includes a first connecting seat and a second connecting seat fixedly connected to the screen and the base, respectively. The first connecting seat is rotatably connected to the second connecting seat via a pivot. The hinge structure also includes a support component rotatably mounted on the pivot, a torque adjustment component slidably or fixedly mounted on the pivot, and a transmission component. The transmission component includes a first transmission member and a second transmission member that are linked with the first connecting seat. As the screen enters its open or closed limit position, the first transmission member synchronously drives the support component to rotate and form a supported state on the side of the screen away from the base or a folded state that is synchronously folded with the screen. The second transmission member synchronously presses the torque adjustment component axially along the pivot and forms a gradually increasing torque.
[0009] According to a specific embodiment and preferred aspect of this utility model, the supporting component includes a connecting sleeve and a supporting plate fixedly connected to the connecting sleeve. When in the supporting state, the supporting plate is flush with the bottom surface of the base; when in the folded state, the supporting plate is flush with the back of the screen. Here, when the screen is open, the supporting plate and the bottom surface of the base are flush, forming a common support, resulting in strong stability; simultaneously, when the screen is folded up, the supporting plate is flush with the back of the screen, improving aesthetics.
[0010] Preferably, the first connector and the second connector constitute a connector group, the connector group has two connectors and is close to the opposite sides of the laptop, the connector sleeve corresponds to the two connector groups one by one, and the support plate is U-shaped and integrally formed with the two connector sleeves from both ends.
[0011] According to another specific embodiment and preferred aspect of this utility model, the first transmission component includes a sun gear fixedly mounted on a pivot and located on one side of a first connecting seat, a plurality of planetary gears spaced around the sun gear, and a central shaft correspondingly fixed at the center of each planetary gear. One end of each central shaft is inserted into the first connecting seat, and an internal gear meshing with the plurality of planetary gears is fixedly provided on the inner wall of the connecting sleeve. This design provides high transmission precision and strong transmission stability, facilitating precise linkage between the screen and the support plate. Simultaneously, the gear ratio allows for adjustment of the support plate's rotation speed, thereby adjusting the angle of rotation of the support plate with the screen.
[0012] Preferably, the second transmission component includes a transmission module sleeved on a pivot and located on the side of the sun gear away from the first connecting seat. The other ends of multiple central shafts are respectively inserted into one side of the transmission module. As the transmission module rotates around the pivot, it gradually compresses or releases the torque adjusting component. Here, the structure is simple and easy to install and implement.
[0013] Furthermore, the transmission module is recessed inward from the other side, forming a groove extending around the center line of the pivot. Both ends of the groove form pressing slopes that extend inward from the outside towards the center. As the screen enters its open or closed limit position, the transmission module gradually presses the torque adjustment component from the pressing slopes at the corresponding ends. This facilitates precise control of the consistent torque changes generated when the screen enters its open or closed limit position.
[0014] According to another specific embodiment and preferred aspect of this utility model, the torque adjustment component includes an adjustment module slidably disposed on a pivot and an elastic member that drives the adjustment module to maintain a tendency to move towards the transmission module, wherein the adjustment module has an abutment portion extending towards the transmission module. Here, based on the elastic pressure of the elastic member, it is ensured that the adjustment module can form pressure with the compression slope, thereby improving the reliability of torque adjustment.
[0015] Preferably, there are multiple grooves that are spaced apart around the center line of the pivot, and there are multiple contact portions that correspond to and fit with the grooves one by one.
[0016] According to another specific embodiment and preferred aspect of the present invention, the first connecting seat includes a seat body forming an assembly channel and a rounded member disposed within the assembly channel, wherein the rounded member is sleeved on a pivot and generates torque.
[0017] Furthermore, a first plane is formed on the outer casing, and a second plane is formed on the pivot. As the screen flips, the first plane and the second plane align or intersect. Here, there is an angle difference between the planes at the mating parts of the outer casing and the pivot, which helps to accelerate the closing effect, plays a self-sealing role, and prevents poor closure phenomena such as gaps between the screen and the base.
[0018] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:
[0019] When a laptop is opened for use, if the force that drives the screen module to rotate at an increasingly larger angle relative to the base continues, the screen can easily cause the base to tilt upwards, severely reducing the user experience. If the torque of a conventional torque component is too high, it will affect the opening and closing feel; if the torque is too low, it will easily lead to insufficient torque, causing the screen to wobble or poorly close between the screen and the base when it is at its open or closed limit (a gap exists between the screen and the base). This application provides an overall design for the hinge structure applicable to laptops, cleverly addressing the shortcomings and defects of existing technologies. With this hinge structure, when the screen flips to its open limit position, the first and second transmission components are linked to the first connecting base. The first transmission component drives the support component to rotate, forming a support state that supports the side of the screen away from the base, preventing the base from tilting when the screen is subjected to normal thrust. Simultaneously, the second transmission component presses the torque adjustment component axially along the pivot, generating a gradually increasing torque to prevent the screen from wobbling when open. Similarly, when the screen flips to its closed limit position, the first transmission component drives the support component to rotate, forming a folded state synchronized with the screen, and the second transmission component simultaneously presses the torque adjustment component axially along the pivot, generating a gradually increasing torque to prevent poor closure between the screen and the base. Therefore, compared with the prior art, this utility model is based on linkage and transmission. On the one hand, the support component opens or closes with the movement of the screen. When the screen is open, the support component and the base support the screen on both sides simultaneously, which effectively prevents the screen from being forced to lift the base upwards and greatly improves the user experience. On the other hand, when the screen enters the extreme position, the torque can be increased synchronously to effectively avoid the screen from shaking or failing to close properly when opening.

[0032] like Figures 1 to 5 As shown, the laptop computer in this embodiment includes a base that rests flat on a table and a screen. The hinge structure of this embodiment for the laptop computer includes a first connecting base 1, a second connecting base 2, a transmission component 3, a support component 4, and a torque adjustment component 5.
[0033] Specifically, a pivot s is fixedly provided on the second connecting seat 2, and the first connecting seat 1 is rotatably connected to the second connecting seat 2 through the pivot s; the first connecting seat 1 and the second connecting seat 2 constitute a connecting group, and the connecting group has two parts and is close to the opposite sides of the laptop.
[0034] Meanwhile, the first connecting seat 1 includes a seat body 10 forming an assembly channel t and a rounded member 11 disposed within the assembly channel t, wherein the rounded member 11 is sleeved on the pivot s and used to generate torque. The purpose of this arrangement is to facilitate the achievement of the best screen flipping feel.
[0035] A first plane 110 is formed on the round part 11, and a second plane (not shown in the figure, but it is easy to imagine) is formed on the pivot s. As the screen flips, the first plane 110 and the second plane fit together or intersect. Here, there is an angle difference between the planes of the round part and the pivot mating part, which helps to accelerate the closing effect, play a self-closing role, and prevent poor closing phenomena such as gaps between the screen and the base.
[0036] In this example, there are two transmission components 3, each corresponding to one of the two connecting groups. The transmission component 3 includes a first transmission member 31 and a second transmission member 32 that are linked with the corresponding first connecting seat 1. The support component 4 is rotatably mounted on the pivot s, and the torque adjustment component 5 is slidably or fixedly mounted on the pivot s. As the screen enters the open limit position or the closed limit position, the first transmission member 31 synchronously drives the support component 4 to rotate and form a support state on the side of the screen away from the base or a folded state that is folded synchronously with the screen. The second transmission member 32 synchronously presses the torque adjustment component 5 in the axial direction of the pivot s and forms a gradually increasing torque.
[0037] In some specific embodiments, the first transmission component 31 includes a sun gear 310 fixedly mounted on the pivot s and located on one side of the first connecting seat 1, a plurality of planet gears 311 spaced around the sun gear 310, and a central shaft 312 fixed at the center of each planet gear 311 and parallel to the pivot s. One end of the central shafts 312 is inserted into the first connecting seat 1, thereby enabling the plurality of planet gears 311 to rotate synchronously around the sun gear 310 as the first connecting seat 1 rotates. The sun gear 310 and planet gears 311 are conventionally designed gears. The second transmission component 32 includes a transmission module 320 sleeved on the pivot s and located on the side of the sun gear 310 away from the first connecting seat 1. The other ends of the central shafts 312 are respectively inserted into one side of the transmission module 320. As the transmission module 320 rotates around the pivot s, it gradually compresses or releases the torque adjusting component 5.
[0038] To further facilitate implementation, the transmission module 320 is recessed inward from the other side, forming a groove c extending around the centerline of the pivot s. At both ends of the groove c are pressing inclined surfaces c0 extending inward from the outside towards the center. The inclination angles of the pressing inclined surfaces c0 at both ends are consistent. As the screen enters the open or closed limit position, the transmission module 320 gradually presses the torque adjustment component 5 from the corresponding pressing inclined surfaces c0. This facilitates precise control of the consistent torque change generated when the screen enters the open or closed limit position; simultaneously, by controlling the depth of the groove between the pressing inclined surfaces c0 at both ends, interference with the torque during the screen's flipping process between the open and closed limit positions is avoided.
[0039] In this example, the support component 4 includes a connecting sleeve 40 and a support plate 41 fixedly connected to the connecting sleeve 40. When in the supporting state, the support plate 41 is flush with the bottom surface of the base. Simultaneously, a receiving groove can be provided from the back of the screen. When in the folded state, the support plate 41 retracts into the receiving groove and is flush with the back of the screen. Here, when the screen is open, the support plate and the bottom surface of the base are flush, forming a common support, resulting in strong stability; at the same time, when the screen is folded up, the support plate is flush with the back of the screen, improving aesthetics.
[0040] In some specific embodiments, the connecting sleeve 40 corresponds one-to-one with the two connecting groups, and the support plate 41 is U-shaped and integrally formed with the two connecting sleeves 40 from both ends. The inner wall of the connecting sleeve 40 is fixedly provided with internal gears 400 that mesh with the corresponding plurality of planetary gears 311. Here, the transmission accuracy is high and the transmission stability is strong, facilitating precise linkage between the screen and the support plate. Simultaneously, based on the gear pair transmission ratio, the rotation speed of the support plate can be adjusted, thereby adjusting the angle of rotation of the support plate with the screen.
[0041] Furthermore, the torque adjustment component 5 includes an adjustment module 50 slidably mounted on the pivot s, and an elastic element 51 (e.g., a spring) that drives the adjustment module 50 to maintain a tendency to move toward the transmission module 320. The adjustment module 50 has an abutment portion 500 extending toward the transmission module 320. Here, based on the elastic pressure of the elastic element, it is ensured that the adjustment module can form pressure with the compression ramp, improving the reliability of torque adjustment.
[0042] Specifically, there are multiple grooves c, which are spaced apart around the center line of the pivot s, and there are multiple contact parts 500 that correspond to and cooperate with each groove c.
[0043] In summary, with this hinge structure, when the screen flips to its open limit position, the first and second transmission components are linked to the first connecting seat. The first transmission component drives the support component to rotate, forming a support state that supports the side of the screen away from the base, preventing the base from tilting when the screen is subjected to normal thrust. At the same time, the second transmission component simultaneously presses the torque adjustment component axially on the pivot, forming a gradually increasing torque to prevent the screen from shaking when open. Similarly, when the screen flips to its closed limit position, the first transmission component drives the support component to rotate, forming a folded state that is synchronized with the screen. The second transmission component simultaneously presses the torque adjustment component axially on the pivot, forming a gradually increasing torque to prevent poor closure between the screen and the base. Therefore, compared with the prior art, this utility model is based on linkage and transmission. On the one hand, the supporting component opens or closes with the movement of the screen. When the screen is open, the supporting component and the base support the screen simultaneously on both sides, effectively preventing the screen from causing the base to tilt upwards due to force, thus greatly improving the user experience. On the other hand, the torque can be increased synchronously when the screen enters the limit position, effectively avoiding screen shaking or poor closure when opening. Thirdly, the transmission precision is high and the transmission stability is strong, which facilitates precise linkage between the screen and the supporting plate. At the same time, the rotation speed of the supporting plate can be adjusted based on the gear pair transmission ratio, thereby adjusting the angle of the supporting plate as the screen rotates. Fourthly, it is easy to accurately control the torque change generated when the screen enters the open or closed limit position. Fifthly, based on the elastic pressure of the elastic element, it ensures that the adjustment module can form a pressure with the extrusion slope, improving the reliability of torque adjustment. Sixthly, the angle difference between the plane of the round part and the pivot mating part helps to accelerate the closing effect, playing a self-closing role and preventing poor closure phenomena such as gaps between the screen and the base.
[0044] The present utility model has been described in detail above, with the purpose 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.
