Description

Technical Field

[0001] This utility model relates to the field of laptop computer hinge technology, specifically an adjustable laptop computer hinge. Background Technology

[0002] With the development of technology, various electronic products have emerged, bringing tremendous changes to people's lives. In particular, the use of computers has changed people's lifestyles and accelerated their pace of life. In the past two decades, with the development of materials science and the emergence of smaller integrated chips, laptops have become small, thin, light, and easy to carry. Most laptops now have a clamshell design. To meet the design requirements of being thin, small, and light, modern laptops are generally designed with two parts: a base consisting of the main body and keyboard, and a top cover consisting of the display screen and the lid. The existing Chinese patent document CN107131203B discloses a positioning hinge for laptops. It points out that current laptops typically have annular oil-guiding grooves on the hinge. However, this structure results in slow heat dissipation, leading to localized overheating and causing the lubricating oil in the oil groove to melt easily. This requires the lubricating oil to have a high melting point. Furthermore, the annular oil-guiding grooves on the hinge are not conducive to lubricating oil storage, potentially causing oil leakage when opening and closing the laptop lid. Additionally, the annular oil-guiding grooves on the hinge are not conducive to forming a uniform oil film. The proposed solution is to incorporate several loose fin rings and several tight fin rings on the positioning hinge of the laptop, alternating between them. This reduces torque attenuation, improves product lifespan, and allows for easy adjustment of the number of loose and tight fin rings according to different applications and products, saving on operating costs.

[0003] However, in the above solutions and existing technologies, the hinge of the laptop may rust or corrode after being rotated for a long time. This will make it difficult for the laptop to rotate, and the hinge of the laptop must be replaced, which increases the cost of inspection and maintenance and causes additional losses.

[0004] Therefore, this utility model proposes an adjustable laptop hinge to solve the above problems. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0025] Example 1: An adjustable laptop hinge includes a first bracket 1, a second bracket 2, a rivet 3, a first pivot 4, a second pivot 5, a connecting piece 6, a fixing connecting piece 7, a fixing screw 8, a gear 9, a driving gear 10, and a lubrication assembly; the first bracket 1 and the first pivot 4 are fixedly mounted on the first bracket 1 by the rivet 3, the second pivot 5 is fixedly mounted on the second bracket 2 by the rivet 3, the connecting piece 6 is mounted on the first pivot 4 and the second pivot 5, the fixing connecting piece 7 is sleeved on the first pivot 4 and the second pivot 5, the fixing screw 8 is fixedly mounted on the fixing connecting piece 7, the gear 9 is positioned between the connecting piece 6 and the fixing connecting piece 7, and the driving gear 10 is fixedly mounted on the connecting piece 6; the gear 9 is sleeved on the first pivot 4 and the second pivot 5, and the gear 9 is positioned between the connecting piece 6 and the fixing connecting piece 7.

[0026] In use, the first rotating shaft 4 is first fixed to the first bracket 1 by rivets 3, and the second rotating shaft 5 is fixed to the second bracket 2 by rivets 3. Then, the connecting piece 6 is fitted onto the first rotating shaft 4 and the second rotating shaft 5. The driving gear 10 is fixed to the connecting piece 6 by screws, and the driving gear 10 can rotate. Then, the gear 9 is fitted onto the first rotating shaft 4 and the second rotating shaft 5, and the fixing connecting piece 7 is fitted onto the first rotating shaft 4 and the second rotating shaft 5. The gear 9 is set on the connecting piece 6 and the fixing connecting piece 7. The second bracket 2 is fixedly set on one side of the laptop's host, and the first bracket 1 is fixedly set on one side of the laptop's display screen. When the laptop is opened and closed, the first bracket 1 will rotate, thereby driving the first rotating shaft 4 to rotate, causing the gear 9 fitted onto the first rotating shaft 4 to rotate. The gear 9 will cause the driving gear 10 to rotate as well, thereby causing the symmetrically arranged gears 9 to rotate.

[0027] Example 2: Based on Example 1, the lubrication assembly includes an oil inlet 1101, a rubber washer 1102, an oil inlet pipe 1103, an oil-proof sleeve 1104, a fixed rubber sleeve 1105, an oil outlet pipe 1106, an oil collection box 1107, and an oil-proof ring 1108. The oil inlet 1101 is fixedly disposed on one side of the connecting piece 6, the rubber washer 1102 is sleeved on the oil inlet 1101, the oil inlet pipe 1103 is fixedly disposed inside the connecting piece 6, and the oil outlet pipe 1106 is fixedly disposed inside the fixed connecting piece 7. The oil-proof sleeves 1104 are symmetrically arranged... The oil-proof sleeve 1104 is placed on both sides of the gear 9 and is fitted onto the second rotating shaft 5 when fixed, and is positioned between the gear 9 and the connecting piece 6; the fixing rubber sleeve 1105 is fitted onto the fixing screw 8 and is positioned between the fixing screw 8 and the fixing connecting piece 7; the oil collection box 1107 is positioned on one side of the fixing connecting piece 7 and is connected to the oil outlet pipe 1106; the oil-proof sleeve 1108 is fitted onto the second rotating shaft 5 and is positioned between the second rotating shaft 5 and the connecting piece 6.

[0028] In use, first, set the angle between the first bracket 1 and the second bracket 2 to 180 degrees, with the oil inlet 1101 facing upwards. Unscrew the screw securing the oil inlet 1101, pour in a certain amount of lubricating oil, and then close the screw. The lubricating oil enters through the oil inlet pipe 1103 and lubricates the inner wall of the gear 9, preventing rust on the gear 9 and the second shaft 5 or the first shaft 4. After lubrication is complete, the lubricating oil enters the oil outlet pipe 1106 inside the fixed connecting piece 7 and flows into the oil collection box. In 1107, during lubrication, the oil-proof sleeve 1104, the fixed rubber sleeve 1105, and the oil-proof ring 1108 can all prevent the lubricating oil from leaving the lubrication component, so that the lubricating oil can only move inside the lubrication component. After lubrication for a period of time, the lubricating oil is no longer usable. Then, the first bracket 1 and the second bracket 2 are closed, and the oil collection box 1107 at the oil outlet pipe 1106 is opened to pour out the waste oil collected inside the oil collection box 1107. Then, the oil collection box 1107 is reconnected to the oil outlet pipe 1106.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
