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] A laptop computer, also known as a portable computer, is a small, lightweight personal computer designed for use while on the go.

[0003] Laptops, as portable computing devices, play an increasingly important role in daily life and work. For example, Chinese Patent Publication No. "CN220855555U" provides a laptop hinge, including a main unit and a screen. The main unit has a first mounting groove on the side near the screen, and the screen has a second mounting groove on the side near the main unit. This utility model, with its main unit, hinge, and positioning components, allows for easy installation of the hinge. By pushing the knob at the bottom of the hinge, two symmetrical movable sleeves on the threaded rod surface move simultaneously in opposite directions, pressing the pressure block at the other end of the corresponding second positioning pin towards the inner wall of the hinge. This engages the second positioning pin in the corresponding slot, while the first positioning pin on the movable sleeve is inserted into the corresponding limiting hole, thus completing the hinge installation. Compared to some existing laptop hinges that require opening the casing for installation or replacement, this design significantly improves the convenience of laptop hinge replacement, increases installation efficiency, and saves manpower.

[0004] Currently, most laptops use a damping hinge and damping sleeve to connect the keyboard base and the screen. While this allows for quick assembly and opening / closing of the screen and keyboard base, as well as positioning of the screen after opening, it can easily lead to slippage over time. Additionally, if lint, dust, or dirt accumulates between the damping hinge and the damping sleeve, the hinge and the damping sleeve can easily become stuck and jammed. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a laptop hinge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a laptop hinge, including a positioning shaft, one end of which is provided with a base positioning plate, the end of which is welded and fixed to the end face of the positioning shaft, and the surface of the base positioning plate is provided with a through mounting hole, which is symmetrically distributed along both sides of the base positioning plate.

[0008] The surface of the positioning shaft is provided with a limiting ring, and the inner side of the limiting ring is fixedly sleeved with the surface of the positioning shaft. The surface of the positioning shaft is provided with a bushing, one end of which is tightly attached to the surface of the limiting ring. The outer ring wall of the bushing is provided with a screen connector seat, and the surface of the screen connector seat is provided with a second mounting hole, which is symmetrically distributed along the vertical position of the screen connector seat.

[0009] A limit rod is provided on the outer ring wall of the positioning shaft. The limit rod has a right-angle bent structure. One end of the limit rod is welded to the surface of the positioning shaft. A limit plate is fixed on the outer ring wall of the bushing.

[0010] In detail, the inner ring wall of mounting hole one and the inner ring wall of mounting hole two are both smooth or threaded surfaces.

[0011] In detail, the end of the positioning shaft away from the limiting ring is provided with an external thread, and a threaded sleeve is threadedly connected to the surface of the external thread. One side of the threaded sleeve is tightly fitted to the end face of the shaft sleeve.

[0012] In detail, the outer ring wall of the threaded sleeve is provided with anti-slip protrusions, and there are several anti-slip protrusions that are evenly distributed.

[0013] In detail, a gap is provided between the bushing and the positioning shaft, and several grooves are provided on the inner ring wall of the bushing.

[0014] In detail, the groove is provided with an extrusion head, and the end of the extrusion head is closely attached to the surface of the positioning shaft.

[0015] In detail, a spring is provided inside the groove, and the two ends of the spring are fixedly assembled to the inner wall of the groove and the surface of the extrusion head, respectively.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. When the overall rotating structure needs to be installed with the computer, the base positioning plate is fixed to the base of the laptop with screws, so that the positioning shaft can be fixed to the base. Then, the screen and screen connector are fixed with screws, so that the screen and the base can be connected. The screen can rotate relative to the base by rotating the bushing on the positioning shaft. The position of the bushing on the positioning shaft can be restricted by the limit ring. The threaded sleeve and the external thread are threaded together to squeeze the bushing, so that the bushing has a damping effect when rotating. After the screen is opened, the limit plate contacts the limit rod to limit the maximum position of the screen flipping open.

[0018] 2. By setting several extrusion head structures on the inner side of the bushing, a gap is left when it rotates with the positioning shaft. Even if lint, dust and dirt enter, the bushing and positioning shaft will not get stuck during rotation. Through the reset effect of the spring, the extrusion head and positioning shaft can produce sufficient compaction effect, ensuring the stable rotation of the bushing and positioning shaft.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A laptop hinge includes a positioning shaft 1, a base positioning plate 11 is provided at one end of the positioning shaft 1, the end of the base positioning plate 11 is welded and fixed to the end face of the positioning shaft 1, and a mounting hole 12 penetrating through the surface of the base positioning plate 11 is provided, and the mounting holes 12 are symmetrically distributed along both sides of the base positioning plate 11.

[0026] A limiting ring 13 is provided on the surface of the positioning shaft 1. The inner side of the limiting ring 13 is fixedly sleeved with the surface of the positioning shaft 1. A bushing 14 is provided on the surface of the positioning shaft 1. One end of the bushing 14 is tightly attached to the surface of the limiting ring 13. A screen connector 15 is provided on the outer ring wall of the bushing 14. The surface of the screen connector 15 is provided with a second mounting hole 16. The second mounting hole 16 is symmetrically distributed along the vertical position of the screen connector 15.

[0027] A limiting rod 17 is provided on the outer ring wall of the positioning shaft 1. The limiting rod 17 is a right-angle bent structure. One end of the limiting rod 17 is welded to the surface of the positioning shaft 1. A limiting plate 18 is fixed on the outer ring wall of the bushing 14.

[0028] It should be further noted that the inner walls of mounting hole 12 and mounting hole 16 are both smooth or threaded, which facilitates the installation of screws or bolts through the corresponding mounting holes to the screen and base respectively.

[0029] It should be further explained that the end of the positioning shaft 1 away from the limiting ring 13 is provided with an external thread 2, and the surface of the external thread 2 is threadedly connected to a threaded sleeve 21. One side of the threaded sleeve 21 is tightly attached to the end face of the bushing 14. By rotating the threaded sleeve 21 on the external thread 2, the bushing 14 can be squeezed, thereby giving the bushing 14 a damping effect when rotating.

[0030] It should be further noted that the outer ring wall of the threaded sleeve 21 is provided with anti-slip protrusions 22. There are several anti-slip protrusions 22, which are evenly distributed. This allows the threaded sleeve 21 to be rotated and adjusted by moving the anti-slip protrusions 22 with your fingers without disassembling the machine.

[0031] It should be further noted that there is a gap between the bushing 14 and the positioning shaft 1, and several grooves 3 are provided on the inner ring wall of the bushing 14. The distribution of grooves 3 in multiple positions makes the arrangement of the extrusion head 32 more uniform.

[0032] It should be further explained that an extrusion head 32 is provided inside the groove 3. The end of the extrusion head 32 is closely attached to the surface of the positioning shaft 1. The extrusion head 32 can contact the positioning shaft 1, so as to realize the rotational support of the bushing 14 on the positioning shaft 1.

[0033] It should be further explained that a spring 31 is provided inside the groove 3. The two ends of the spring 31 are fixedly assembled with the inner wall of the groove 3 and the surface of the extrusion head 32, respectively. Through the reset effect of the spring 31, the extrusion head 32 contacts the positioning shaft 1, which can achieve a stable compaction support effect.

[0034] Working method: When the overall rotating structure needs to be installed with the computer, the base positioning plate 11 is fixed to the base of the laptop with screws, so that the positioning shaft 1 can be fixed to the base. Then, the screen and screen connector 15 are fixed with screws, so that the screen and the base can be connected. The screen can rotate relative to the base by rotating the bushing 14 on the positioning shaft 1. The position of the bushing 14 on the positioning shaft 1 can be restricted by the limiting ring 13. The bushing 14 can be squeezed by the threaded sleeve 21 and the external thread 2, so that the bushing 14 has a damping effect when rotating. After the screen is opened, the screen can be limited to the maximum position of flipping open by the contact between the limiting plate 18 and the limiting rod 17.

[0035] By providing several extrusion heads 32 on the inner side of the bushing 14, a gap is left when it rotates with the positioning shaft 1. Even if lint, dust and dirt enter, the bushing 14 and the positioning shaft 1 will not get stuck during rotation. Through the reset effect of the spring 31, the extrusion heads 32 and the positioning shaft 1 can produce sufficient compaction effect, ensuring the stable rotation of the bushing 14 and the positioning shaft 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
