Description

Technical Field

[0001] This utility model relates to the field of laptop hinge technology, specifically a clamping mechanism for laptop hinges. Background Technology

[0002] A laptop computer, also known as a notebook computer, handheld computer, or lap computer, is a small, portable personal computer. In 1985, Toshiba launched the T1000, which first introduced the concept of a "laptop computer" to people. The main body of the laptop computer and the display screen are connected by a hinge, which makes it easy to fold the main body and the display screen, making it more portable.

[0003] To adjust the angle between the laptop body and the screen, a clamping mechanism is usually installed to press the hinge, thereby increasing the friction of the hinge and preventing the screen from rotating without external force, thus stabilizing the angle between the laptop body and the screen.

[0004] While existing clamping structures can clamp the hinge through friction, they are not convenient for adjusting the pressure on the hinge, which can easily lead to the hinge being too loose or too tight, thus affecting the rotation between the laptop body and the display screen. Therefore, there is a need to provide a clamping mechanism for laptop hinges. Utility Model Content

[0005] The purpose of this invention is to provide a clamping mechanism for a laptop hinge, in order to solve the problem that although the existing clamping structure mentioned in the background art can clamp the hinge through friction, it is not convenient to adjust the pressure on the hinge, which can easily lead to the hinge being too loose or too tight, thereby affecting the rotation between the laptop body and the display screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for a laptop computer hinge, comprising a host connecting piece, wherein mounting holes are provided at all four corners of the host connecting piece, a computer host is fixedly connected to the bottom of the host connecting piece, a hinge assembly is fixedly installed at one end of the top of the host connecting piece, a clamping component is installed at one end of the hinge assembly, an adjusting component for adjusting the tightness is engaged with the outer side of the clamping component, and a limiting component is engaged with the inner side of the adjusting component.

[0007] Preferably, the rotating shaft assembly includes two mounting blocks, both of which are fixedly mounted on the top of the host connecting piece. A shaft is fixedly mounted between the two mounting blocks. A transverse connecting piece and a longitudinal connecting piece are rotatably mounted on the outside of the shaft. A computer display screen is fixedly mounted on the outside between the transverse connecting piece and the longitudinal connecting piece.

[0008] Preferably, the clamping assembly includes a lead screw, which is fixedly installed at one end of the shaft. A transmission gear is threaded to one end of the lead screw. A spring washer is fitted on one side of the connection between the transmission gear and the lead screw. A damping plate is fitted on one side of the connection between the spring washer and the lead screw. The damping plate is in contact with the longitudinal connecting piece. Through the spring washer, the elastic deformation of the spring can absorb the instantaneous impact force when opening and closing the screen, avoiding wear or loosening of the hinge due to rigid collision. When the laptop is closed quickly, the spring is compressed to slow down the screen's falling speed and reduce the impact on the body.

[0009] Preferably, the adjustment assembly includes a mounting plate, which is fixedly mounted on one end of a lead screw. A rotating shaft is rotatably mounted on one end of the mounting plate, and an adjusting gear is fixedly mounted on one end of the rotating shaft. The adjusting gear is meshed with the outside of a transmission gear. Users can adjust the tightness of the rotating shaft according to their own usage habits. A rotating shaft with appropriate tightness can evenly distribute the stress during opening and closing, preventing deformation at the connection between the body and the screen due to uneven force.

[0010] Preferably, a knob is fixedly installed at the end of the rotating shaft away from the lead screw, passing through the housing of the computer display screen. Multiple tension scales are equidistantly arranged on the outer side of the knob, and multiple locking grooves are equidistantly arranged on the inner side of the knob. Traditional shaft adjustment relies on feel, while the scale design converts the tension into a quantifiable parameter, allowing users to accurately position it according to their needs.

[0011] Preferably, the limiting component includes a sliding groove, which is formed on one side of the computer display screen housing. A limiting block is slidably connected inside the sliding groove. A locking spring is fixedly installed at one end of the limiting block, and the locking spring is fixedly installed at one end inside the sliding groove. The limiting block is engaged with the locking groove.

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

[0013] By adjusting the hinge, if the laptop is too tight or too loose when opened, the tightness of the screen opening and closing can be adjusted by turning the knob on the outside of the computer screen casing. There is no need to disassemble the laptop and adjust the hinge tightness. This not only avoids the hinge being too tight or too loose, which would affect the rotation between the laptop body and the screen, but also increases the convenience of adjustment.

[0014] The scale on the knob allows you to easily check the current tension of the shaft, and then make precise adjustments to the tension. Attached Figure Description

[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model provides a clamping mechanism for a laptop computer hinge, including a host connecting piece 1. Each of the four corners of the host connecting piece 1 is provided with a mounting hole. A computer host 19 is fixedly connected to the bottom of the host connecting piece 1. A hinge assembly is fixedly installed at one end of the top of the host connecting piece 1. A clamping component is installed at one end of the hinge assembly. An adjustment component for adjusting the tightness is engaged with the outer side of the clamping component. A limit component is engaged with the inner side of the adjustment component.

[0022] Furthermore, the rotating shaft assembly includes two mounting blocks 2, both of which are fixedly mounted on the top of the host connecting piece 1. A shaft 3 is fixedly mounted between the two mounting blocks 2. A transverse connecting piece 4 and a longitudinal connecting piece 5 are rotatably mounted on the outside of the shaft 3. A computer display screen 8 is fixedly mounted on the outside between the transverse connecting piece 4 and the longitudinal connecting piece 5.

[0023] Furthermore, the clamping assembly includes a lead screw 9, which is fixedly installed at one end of the shaft 3. A transmission gear 10 is threadedly connected to one end of the lead screw 9. A spring washer 7 is fitted on one side of the connection between the transmission gear 10 and the lead screw 9. A damping plate 6 is fitted on the other side of the connection between the spring washer 7 and the lead screw 9. The damping plate 6 is in contact with the longitudinal connecting piece 5. The adjusting assembly includes a mounting plate 13, which is fixedly installed at one end of the lead screw 9. A rotating shaft 12 is rotatably mounted on one end of the mounting plate 13. An adjusting gear 11 is fixedly mounted on one end of the rotating shaft 12. The gear 11 is meshed with the outside of the transmission gear 10. The end of the rotating shaft 12 away from the lead screw 9 passes through the housing of the computer display screen 8 and is fixedly installed with a knob 14. Multiple tension scales 15 are equidistantly arranged on the outside of the knob 14, and multiple engagement grooves 16 are equidistantly opened on the inside of the knob 14. Rotating the knob 14 causes the rotating shaft 12 to rotate at one end of the mounting plate 13. When the rotating shaft 12 rotates, it drives the adjusting gear 11 fixedly installed at one end to rotate, meshing with the transmission gear 10 and adjusting the tension of the rotating shaft.

[0024] Furthermore, the limiting component includes a sliding groove, which is formed on one side of the computer display screen 8 housing. A limiting block 18 is slidably connected inside the sliding groove. A locking spring 17 is fixedly installed at one end of the limiting block 18. The locking spring 17 is fixedly installed inside the sliding groove. The limiting block 18 is engaged with the locking groove 16. When the knob 14 is rotated, the limiting block 18 and the locking spring 17 will be pushed back into the sliding groove under pressure. When the knob is rotated to the next locking groove 16 position, the locking spring 17 is released from force, causing the limiting block 18 to reset back into the corresponding locking groove 16. This gives the knob 14 a stop lever when rotating, indicating that a certain tightness scale 15 has been reached.

[0025] In this embodiment, the computer host 19 is fixedly connected to the host connecting piece 1, and the computer display screen 8 is fixedly connected to the horizontal connecting piece 4 and the vertical connecting piece 5. When opening and closing the computer display screen 8, the horizontal connecting piece 4 and the vertical connecting piece 5 rotate along the axis 3 to achieve opening and closing. The friction is increased by the spring washer 7 and the damping piece 6. The tightness determines the magnitude of friction and the ease of opening and closing the computer display screen 8. The current tightness of the rotating shaft can be adjusted by the tightness scale 15 on the outside of the knob 14. Multiple tightness scales 15 correspond one-to-one with multiple engagement slots 16. When adjusting the tightness, the knob 14 is rotated to make the adjusting gear 11 rotate to engage the transmission gear 10. Rotation in the forward direction makes the transmission gear 10 move closer and squeeze to increase friction, while rotation in the reverse direction makes the transmission gear 10 move away to reduce friction, thereby adjusting the tightness of the rotating shaft.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
