Description

Technical Field

[0001] This utility model relates to the field of computer hinge technology, specifically a gear-driven computer hinge. Background Technology

[0002] With the popularization of modern electronic devices, portable computing devices such as laptops have become indispensable tools in daily life and work. The portability and frequency of use of these devices have placed higher demands on the quality of the hinges. Traditional computer hinges usually adopt simple mechanical structures. Although they can meet the basic opening and closing functions, they are prone to severe wear due to the lack of an effective lubrication mechanism during long-term use, which in turn affects their service life and user experience.

[0003] In the existing technology, the lubrication of the gear-driven computer spindle mainly relies on a small amount of lubricating oil added at the factory. However, during use, this lubricating oil will gradually be lost. When the lubricating oil is gradually lost and depleted, the spindle will rotate directly under dry friction, which will generate a lot of heat. Since the spindle itself has a slow heat dissipation rate, this continuous high temperature will seriously affect its service life.

[0004] Therefore, a gear-driven computer spindle is needed to solve the problem that existing computer spindles have a high rate of lubricant loss, which affects the rotation of the spindle and leads to a short service life. Utility Model Content

[0005] The purpose of this invention is to provide a gear-driven computer shaft to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear-driven computer shaft, comprising a shaft body, a helical gear, and washers. A connecting portion is installed at the front end of the shaft body; a slot is formed in the middle of the helical gear; an oil reservoir is formed inside the connecting portion; multiple oil outlet holes are formed on both the upper and lower sides of the connecting portion; and rubber pads are installed on both the left and right sides of the connecting portion. Preferably, a sponge block is installed on the inner wall of the oil reservoir; multiple fitting grooves are formed on both the upper and lower sides of the sponge block; and ball bearings are installed on the inner wall of the oil outlet holes.

[0007] Preferably, the balls are mounted on the inner wall of the fitting groove on the side away from the slot, and the balls are evenly distributed.

[0008] Preferably, two mounting plates are installed on the rear side of the rubber pad, and rubber balls are installed on the front of the adjacent side of the rubber pad on both the left and right sides. Two mounting grooves are opened on the left and right sides of the rear part of the connecting part, and slots are opened on the left and right sides of the connecting part.

[0009] Preferably, the mounting plate is inserted into the inner wall of the mounting groove, and the width of the mounting plate is smaller than the width of the mounting groove.

[0010] Preferably, the rubber balls on both the left and right sides are engaged with the inner wall of the slot, and the rubber balls are in a state of compression deformation.

[0011] Preferably, the helical gear is inserted into the outside of the connecting part through a slot and pushes the rubber pad, the rubber pad is in a compressed deformation state, and the multiple oil outlet holes are evenly distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The gear-driven computer spindle proposed in this utility model rotates synchronously with the connecting part as the spindle rotates. At this time, the lubricating oil in the oil reservoir is absorbed by the sponge block and gradually released through the gap between the ball bearing and the oil outlet, thereby slowing down the flow rate of the lubricating oil and increasing the lubrication effect of the spindle body. At the same time, the lubricating oil adheres to the outside of the connecting part, which can reduce the generation of heat and thus improve its service life. In addition, the use of rubber pads increases the stability of the insertion between the helical gear and the connecting part, and also facilitates subsequent disassembly and maintenance, further improving the overall performance of the computer spindle.

[0021] 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.

[0022] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a gear-driven computer shaft, including a shaft body 1, a helical gear 3, and a washer 5. A connecting part 2 is installed at the front end of the shaft body 1. A slot 4 is opened in the middle of the helical gear 3. An oil storage groove 9 is opened inside the connecting part 2. Multiple oil outlet holes 7 are opened on the upper and lower sides of the connecting part 2. Rubber pads 6 are installed on the left and right sides of the connecting part 2. The helical gear 3 is inserted into the outside of the connecting part 2 through the slot 4 and pushes the rubber pad 6. The rubber pad 6 is in a compressed deformation state. Thus, when installing the helical gear 3, the slot 4 is inserted into the outside of the connecting part 2 and gradually pushes the rubber pad 6, so that it is in a deformed state, thereby increasing the stability of the helical gear 3 installation. The multiple oil outlet holes 7 are evenly distributed and arranged, so that the outside of the connecting part 2 is covered with lubricating oil through the oil outlet holes 7, increasing the lubrication of the shaft body 1 rotation and reducing the heat generated during rotation, thereby improving the service life of the shaft body 1.

[0023] First, rotate the shaft body 1, causing the connecting part 2 to rotate synchronously on the inner wall of the gasket 5. At this time, the helical gear 3 will also rotate synchronously. Since the connecting part 2 is provided with an oil reservoir 9, the lubricating oil is guided to the inner wall of the oil outlet 7 and gradually allows the lubricating oil to adhere to the outer side of the connecting part 2, thereby reducing the rate of lubricating oil loss and improving the lubricity of the shaft body 1 during rotation. At the same time, it reduces the heat generated when the connecting part 2 rotates, thereby improving the performance and service life of the shaft body 1. In addition, when installing the helical gear 3, first insert it into the front outer side of the connecting part 2 and push against the rubber pads 6 on both sides of the connecting part 2, so that the rubber pads 6 are squeezed and gradually deformed, thereby increasing the stability of the helical gear 3 insertion. Furthermore, the setting of the rubber pads 6 can also reduce the vibration transmission of the helical gear 3, thereby improving the overall performance of the shaft body 1.

[0024] Example 2: Based on Example 1, in order to slow down the loss of lubricating oil, a sponge block 10 is installed on the inner wall of the oil reservoir 9. Multiple fitting grooves 11 are opened on both the upper and lower sides of the sponge block 10. A ball bearing 8 is installed on the inner wall of the oil outlet 7. The side of the ball bearing 8 away from the slot 4 is installed on the inner wall of the fitting groove 11, and the multiple balls bearing 8 are evenly distributed. So when the connecting part 2 rotates, the balls bearing 8 and the oil outlet 7 rotate synchronously. At this time, because the balls bearing 8 are fitted with the fitting groove 11, the balls bearing 8 slowly guide the lubricating oil into the oil outlet 7 and flow outward to the outside of the connecting part 2, so as to slow down the loss of lubricating oil.

[0025] First, rotate the shaft body 1, causing the connecting part 2 to rotate synchronously on the inner wall of the gasket 5. At this time, the helical gear 3 will also rotate synchronously. Since the connecting part 2 is equipped with an oil storage groove 9 and the inner wall of the oil storage groove 9 is equipped with a sponge block 10, the connecting part 2 rotates, causing the ball bearing 8 to rotate on the inner wall of the oil outlet 7. Since one side of the ball bearing 8 is in contact with the fitting groove 11, the ball bearing 8 gradually guides the lubricating oil absorbed by the sponge block 10 to the inner wall of the oil outlet 7, and gradually allows the lubricating oil to adhere to the outer side of the connecting part 2, thereby reducing the rate of lubricating oil loss and improving the lubricity of the shaft body 1 during rotation.

[0026] Example 3: Based on Example 2, in order to facilitate the disassembly and maintenance of the rubber pad 6, two mounting plates 15 are installed on the rear side of the rubber pad 6, and rubber balls 14 are installed on the front of the adjacent side of the left and right sides of the rubber pad 6. Two mounting grooves 12 are opened on the left and right sides of the rear part of the connecting part 2, and slots 13 are opened on the left and right sides of the connecting part 2. The mounting plates 15 are inserted into the inner wall of the mounting grooves 12, and the width of the mounting plates 15 is smaller than the width of the mounting grooves 12, so as to facilitate the tilting of the mounting plates 15 into the inner wall of the mounting grooves 12 for the installation of the rubber pad 6. The rubber balls 14 on the left and right sides are engaged with the inner wall of the slots 13, and the rubber balls 14 are in a compressed deformation state, so as to use the rubber balls 14 to install the rubber pad 6 to one side of the connecting part 2, and facilitate subsequent disassembly and maintenance.

[0027] When the rubber pad 6 is worn and needs maintenance, first pull the helical gear 3 forward to disengage it from the connecting part 2. Then pull the rubber pad 6 to both sides to disengage the rubber ball 14 from the slot 13. Then pull it forward at an angle to disengage the mounting plate 15 from the mounting groove 12. At this point, the rubber pad 6 can be maintained or replaced. After that, move the rubber pad 6 backward at an angle to insert the two mounting plates 15 into the inner wall of the mounting groove 12. Push the front sides of the two gaskets 5 to move them towards each other, thereby causing the rubber ball 14 to be inserted into the inner wall of the slot 13. This fits the rubber pad 6 with the connecting part 2 for subsequent maintenance. Then the helical gear 3 can be reset.

[0028] In actual use, first rotate the shaft body 1, causing the connecting part 2 to rotate synchronously on the inner wall of the gasket 5. At this time, the helical gear 3 will also rotate synchronously. Since the connecting part 2 is equipped with an oil reservoir 9, and the inner wall of the oil reservoir 9 is equipped with a sponge block 10, the connecting part 2 rotates, causing the ball bearing 8 to rotate on the inner wall of the oil outlet 7. Since one side of the ball bearing 8 is in contact with the fitting groove 11, the ball bearing 8 gradually guides the lubricating oil absorbed by the sponge block 10 to the inner wall of the oil outlet 7, and gradually allows the lubricating oil to adhere to the outer side of the connecting part 2, thereby reducing the lubrication... The speed of lubricating oil loss is reduced, and the lubrication of the shaft body 1 during rotation is improved. At the same time, the heat generated when the connecting part 2 rotates is reduced, thereby improving the performance and service life of the shaft body 1. In addition, when installing the helical gear 3, it is first inserted into the front outer side of the connecting part 2 and pushed against the rubber pads 6 on both sides of the connecting part 2, so that the rubber pads 6 are squeezed and gradually deformed, thereby increasing the stability of the helical gear 3 insertion. Furthermore, the setting of the rubber pads 6 can also reduce the vibration transmission of the helical gear 3, thereby improving the overall performance of the shaft body 1.

[0029] When the rubber pad 6 is worn and needs maintenance, first pull the helical gear 3 forward to disengage it from the connecting part 2. Then pull the rubber pad 6 to both sides to disengage the rubber ball 14 from the slot 13. Then pull it forward at an angle to disengage the mounting plate 15 from the mounting groove 12. At this point, the rubber pad 6 can be maintained or replaced. After that, move the rubber pad 6 backward at an angle to insert the two mounting plates 15 into the inner wall of the mounting groove 12. Push the front sides of the two gaskets 5 to move them towards each other, thereby causing the rubber ball 14 to be inserted into the inner wall of the slot 13. This fits the rubber pad 6 with the connecting part 2 for subsequent maintenance. Then the helical gear 3 can be reset.
