Description

Technical Field

[0001] This utility model relates to the field of laptop computer technology, and in particular to a laptop computer hinge. Background Technology

[0002] Laptops are portable and integrated personal computers that represent a miniaturization and mobilization of traditional desktop computers. They are designed to meet users' needs for processing information, working, or entertaining themselves in different scenarios. The laptop hinge is a core component that connects the screen and keyboard base. It not only needs to support the screen to rotate at multiple angles to meet users' different usage needs in work, entertainment, and other scenarios, but also needs to ensure the stability of the connection between the screen and the base to avoid loosening or damage of components due to long-term opening and closing. Therefore, a laptop hinge is particularly needed.

[0003] Patent document CN221991358U, published on November 12, 2024, discloses a laptop rotating bracket that is easy to assemble. By moving a pull plate towards the damping shaft, the pull plate drives a limiting rod to move into the interior of the damping shaft. The limiting rod compresses the elastic element, thereby allowing the limiting rod to be pulled out of the connecting block, thus completing the disassembly of the support plate. However, this laptop rotating bracket relies solely on aligning the limiting rod with the hole in the connecting block for positioning during installation, lacking a precise guiding structure. If there is a slight deviation between the limiting rod and the hole in the connecting block, the position of the pull plate must be repeatedly adjusted to complete the insertion, resulting in low installation efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-5 The present invention provides a technical solution: a laptop hinge frame, including a connecting ear plate 1, a hinge 2 connected inside the connecting ear plate 1, a transmission component 3 disposed inside the connecting ear plate 1, and a mounting component 4 disposed on the outer surface of the hinge 2; Mounting assembly 4 includes a first arc-shaped bushing 401, which is mounted on the outer surface of the rotating shaft 2. An elastic retaining strip 402 is connected to the inner side of the first arc-shaped bushing 401. A second arc-shaped bushing 403 is also mounted on the outer surface of the rotating shaft 2. A positioning groove 404 is formed on the inner side of the second arc-shaped bushing 403. A mounting plate 405 is connected to the outer side of the first arc-shaped bushing 401. Mounting holes 406 are formed on the surface of the mounting plate 405. A retaining block 407 is connected to the surface of the rotating shaft 2. Retaining grooves 408 are formed on the inner sides of both the first arc-shaped bushing 401 and the second arc-shaped bushing 403. The interior of 407 has a telescopic groove 409. A compression spring 410 is connected to the inner end of the telescopic groove 409, and a connecting plate 411 is connected to the outer end of the compression spring 410. A fixing block 412 is connected to the outer side of the connecting plate 411. A fixing hole 413 is provided on the inner side of the slot 408. Through the arrangement of the mounting assembly 4, when the first arc-shaped bushing 401 and the second arc-shaped bushing 403 need to be installed on the rotating shaft 2, the slots 408 on the inner sides of both are first aligned with the locking block 407 on the surface of the rotating shaft 2, and then slid along the extending direction of the locking block 407, so that the locking block 407 is embedded in the slot 408, initially limiting... During the relative rotation and sliding of the bushing and the rotating shaft 2, the fixing block 412 inside the locking block 407 is squeezed by the inner wall of the locking groove 408. This compression is achieved by the compression spring 410 inside the telescopic groove 409 via the connecting plate 411, causing the fixing block 412 to retract into the telescopic groove 409, ensuring smooth sliding of the bushing. When the bushing slides to the preset position, the fixing block 412 aligns with the fixing hole 413 inside the locking groove 408. The compression spring 410 releases its elastic force, pushing the connecting plate 411 to cause the fixing block 412 to pop out and engage with the fixing hole 413, thus completing the axial fixation of the bushing and the rotating shaft 2 and preventing leakage during use. The first arc-shaped bushing 401 is loose, and the elastic retaining strip 402 on the inner side of the first arc-shaped bushing 401 and the positioning groove 404 on the inner side of the second arc-shaped bushing 403 engage with each other, further enhancing the tightness of the connection between the two bushings and preventing relative shaking. Finally, the bushing assembly can be fixed to the screen or body of the laptop through the mounting hole 406 on the surface of the mounting plate 405, achieving a stable connection between the screen and the base. If disassembly or adjustment is required later, simply apply external force to push the bushing, causing the fixing block 412 to be squeezed and retracted again, and the bushing and the pivot 2 can be slid apart along the retaining block 407. The operation is convenient and the fixation is reliable.

[0020] Furthermore, the connecting ear plates 1 are provided with three identical sets, and the back ends of the three sets of connecting ear plates 1 are all connected to the bottom surface of the laptop. One set has a transmission component 3 inside. Through the arrangement of the connecting ear plates 1, the three sets of symmetrically distributed structures can provide multi-point stable support for the hinge 2, disperse the force when the screen is connected to the base, avoid local stress concentration caused by a single set of support, and effectively reduce the risk of deformation of the hinge 2 after long-term use. At the same time, the built-in transmission component 3 in one set not only ensures the concentration of power transmission, but also improves the structural rigidity and impact resistance of the entire hinge frame through the auxiliary support of the other two sets of connecting ear plates 1, ensuring that the screen is stable and does not wobble during rotation and extending the service life of the device.

[0021] Furthermore, the transmission assembly 3 includes a cover plate 301, a drive member 302 is connected inside the connecting ear plate 1, a drive shaft 303 is connected to the output end of the drive member 302, a drive gear 304 is connected to the other end of the drive shaft 303, a rotating gear 305 meshes with the surface of the drive gear 304, a shaft 306 is connected through the surface of the rotating gear 305, a shaft mounting block 307 is connected to the outer end of the shaft 306, and the other end of the shaft 306 is connected to the rotating shaft 2. Through the arrangement of the transmission assembly 3, the drive member 302 generates power after being powered on, and transmits the power to the drive shaft 303, causing it to rotate. The drive shaft 303 drives the drive gear 304 to rotate. Utilizing the gear meshing principle, the drive gear 304 and the rotating gear 305 mesh with each other, transmitting the driving force to the rotating gear. Wheel 305, because the diameter and number of teeth of drive gear 304 are smaller than those of rotating gear 305, can achieve the effect of speed reduction and torque increase, so that rotating gear 305 rotates at a more stable speed and with greater torque. Rotating gear 305 transmits rotational motion through shaft 306. The outer end of shaft 306 is fixed on shaft mounting block 307. This mounting block provides stable support for shaft 306 and ensures smooth rotation. The other end of shaft 306 is connected to rotating shaft 2, thereby driving rotating shaft 2 to rotate and realize automatic adjustment of the laptop screen angle. Cover plate 301 is installed on connecting ear plate 1, which can protect internal drive components 302, transmission shaft 303, gears and other components, prevent dust and foreign objects from entering and affecting the normal operation of transmission component 3, and at the same time play a certain safety protection role.

[0022] Furthermore, the diameter and number of teeth of the drive gear 304 are smaller than those of the rotating gear 305. The rotating gear 305 forms a synchronous rotation structure with the rotating shaft 2 through the shaft 306. By setting up the drive gear 304 and the rotating gear 305, the high-speed, low-torque power output by the drive component 302 can be converted into low-speed, high-torque power through the reduction and torque increase characteristics of gear transmission. This allows the rotating shaft 2 to obtain a smooth and strong driving force, ensuring that the laptop screen rotates stably during opening and closing, avoiding stuttering caused by insufficient power, and reducing the load on the drive component 302, thus extending its service life.

[0023] Furthermore, the shaft mounting block 307 has a bearing groove inside, and the end of the shaft 306 is rotatably connected to the shaft mounting block 307 through the bearing. The outer wall of the shaft mounting block 307 is fixedly connected to the inner wall of the connecting ear plate 1. Through the setting of the shaft mounting block 307, the bearing in the bearing groove provides high-precision rotational support for the shaft 306, effectively reducing the frictional resistance and radial runout when the shaft 306 rotates, ensuring that the power transmitted by the rotating gear 305 can be accurately and stably transmitted to the rotating shaft 2. The fixed connection between the shaft mounting block 307 and the inner wall of the connecting ear plate 1 enhances the overall structural rigidity of the transmission assembly 3, prevents the shaft 306 from shifting during rotation, and ensures the accuracy of the screen rotation action.

[0024] Furthermore, both the first arc-shaped bushing 401 and the second arc-shaped bushing 403 are provided in two identical sets, and each pair of first arc-shaped bushings 401 and second arc-shaped bushings 403 are distributed symmetrically about the central axis of the pivot 2. Through the arrangement of the first arc-shaped bushings 401 and the second arc-shaped bushings 403, the two sets of symmetrically distributed bushings can evenly distribute the force generated when the laptop screen is connected to the base, improving the stability of the pivot frame in supporting the screen. At the same time, the double bushing structure increases the contact area with the pivot 2, making the screen more evenly stressed during rotation, avoiding wear caused by excessive local stress, and extending the service life of the pivot frame.

[0025] Furthermore, the elastic retaining strip 402 is distributed in an arc shape at the inner end of the first arc-shaped bushing 401, and the outer wall of the elastic retaining strip 402 is tightly fitted with the inner wall of the second arc-shaped bushing 403. The elastic retaining strip 402 and the positioning groove 404 form a locking structure. Through the setting of the elastic retaining strip 402 and the positioning groove 404, the elastic deformation capability of the elastic retaining strip 402 makes it tightly locked with the positioning groove 404. After the first arc-shaped bushing 401 and the second arc-shaped bushing 403 are installed, relative rotation or axial displacement between the two sets of bushings can be effectively prevented, further enhancing the connection stability of the bushing assembly. At the same time, this locking structure can also absorb vibration to a certain extent, reduce the shaking generated during the opening and closing of the screen, and improve the user experience.

[0026] Furthermore, the first arc-shaped bushing 401 is mounted on the top surface of the laptop via a mounting plate 405. Multiple sets of mounting holes 406 are provided on the surface of the mounting plate 405. Through the mounting plate 405 and the mounting holes 406, the mounting plate 405 provides a flat and stable connection interface between the first arc-shaped bushing 401 and the top surface of the laptop. The multiple sets of mounting holes 406 can accommodate screws of different sizes, making it convenient for users to install and fix according to actual needs, ensuring a firm connection between the screen and the hinge frame. At the same time, the standardized design of the mounting holes 406 also facilitates later disassembly and maintenance, improving the product's versatility and maintainability.

[0027] Furthermore, the locking blocks 407 are symmetrically distributed on the surface of the rotating shaft 2, and the outer wall size of the locking blocks 407 is adapted to the inner wall size of the locking slot 408. The locking blocks 407 are slidably connected to the first arc-shaped bushing 401 and the second arc-shaped bushing 403 respectively through the locking slot 408. Through the setting of the locking blocks 407 and the locking slot 408, the precisely matched dimensions of the two enable the first arc-shaped bushing 401 and the second arc-shaped bushing 403 to be precisely slidably installed along the rotating shaft 2, playing a guiding and positioning role. The sliding connection method not only facilitates the quick installation and removal of the bushings, but also restricts the circumferential rotation between the bushings and the rotating shaft 2, ensuring that the bushings and the rotating shaft 2 move synchronously when the screen rotates, maintaining structural stability.

[0028] Furthermore, the fixing block 412 forms a telescopic structure with the connecting plate 411 via the compression spring 410, and the end of the fixing block 412 is hemispherical. The fixing block 412 and the fixing hole 413 form a snap-fit ​​structure. Through the arrangement of the compression spring 410, the fixing block 412 and the fixing hole 413, the elastic force of the compression spring 410 pushes the fixing block 412 to automatically snap into the fixing hole 413, thereby achieving axial fixation of the first arc-shaped bushing 401, the second arc-shaped bushing 403 and the rotating shaft 2, preventing the bushings from loosening and falling off during use. The hemispherical design of the fixing block 412 makes it easy to retract under pressure during installation and can be reliably locked after installation. At the same time, only a small external force is needed to disassemble the fixing block 412 from the fixing hole 413, thus taking into account both the ease of installation and the reliability of connection.

[0029] Working Principle: When the entire laptop hinge assembly is working, the transmission component 3 serves as the power source. After the drive component 302 is powered on, it outputs power, which is transmitted to the drive gear 304 via the transmission shaft 303. Through the meshing transmission between the drive gear 304 and the rotating gear 305, a speed reduction and torque increase effect is achieved, transmitting stable and strong power to the shaft 306. Under the high-precision support of the bearing inside the shaft mounting block 307, the shaft 306 rotates smoothly and drives the hinge 2 to rotate, thereby realizing the automatic opening and closing and angle adjustment of the laptop screen. During the screen rotation process, the mounting component 4 plays a key role. Two sets of symmetrically distributed first arc-shaped bushings 401 and second arc-shaped bushings 403 are precisely fitted onto the hinge 2 by the sliding cooperation of the locking block 407 and the locking groove 408. Through the snap-fit ​​structure of the compression spring 410, the fixing block 412 and the fixing hole 413, the bushings are axially fixed to the hinge 2, preventing... The loosening of the hinge assembly, along with the engagement of the elastic clip 402 and the positioning groove 404, further enhances the connection stability of the hinge assembly and ensures the stability of the screen during rotation. The mounting plate 405 securely connects the hinge assembly to the laptop screen through the mounting holes 406, making the screen and the hinge frame a stable whole. In addition, the three sets of connecting ear plates 1 provide multi-point support for the hinge 2, dispersing the force when the screen is connected to the base and reducing the risk of deformation of the hinge 2. The connecting ear plates 1 with the built-in transmission assembly 3 provide power transmission while relying on the auxiliary support of the other two sets of connecting ear plates 1 to enhance the overall rigidity and impact resistance of the hinge frame. The cover plate 301 protects the drive component 302, transmission shaft 303 and other components inside the transmission assembly 3, ensuring the long-term stable operation of the device. Ultimately, the laptop screen can be adjusted smoothly, accurately and reliably at multiple angles, thus completing the use process of a laptop hinge frame.
