Description

Technical Field

[0001] This invention relates to the field of footrest adjustment technology, specifically a structure for adjusting the height of a laptop computer. Background Technology

[0002] A laptop height adjustment mechanism refers to a mechanical device that allows certain components of a laptop (such as the keyboard or screen) to move up and down to adapt to different usage needs or provide a better user experience. It is supported and adjusted by laptop feet. Laptop feet are common functional design components on the bottom of laptops. The feet are made of rubber material to increase friction with the desktop, preventing the laptop from sliding or falling. They are especially effective on smooth surfaces and can reduce the impact of desktop vibrations on delicate components such as the laptop hard drive, reducing the risk of physical damage.

[0003] Currently used laptop feet adjust the overall height of the laptop. When users need to adjust the keyboard orientation, they need to remove the laptop feet and adjust their installation angle to achieve the purpose of adjusting the laptop keyboard angle. The adjustment process is relatively troublesome. In order to make it easier for users to adjust the keyboard height, an adjustable height foot structure has been developed. Summary of the Invention

[0010] Furthermore, the inner wall of the semicircular spring contacts the surface of the cross groove rod, and a number of resistance grooves are provided, which are arranged circumferentially around the cross groove rod. The surface of the triangular plate contacts the inner wall of the resistance groove, and the surface of the cross rod contacts the inner wall of the cross groove rod.

[0011] Furthermore, the clamping component includes a telescopic rod, the top of which is fixedly connected to the top of the inner wall of the right-angle plate, a clamping plate fixedly connected to the bottom of the telescopic rod, a vertical plate fixedly connected to the bottom of the clamping plate, an auxiliary plate slidably connected to the surface of the vertical plate, a threaded rod rotatably connected to the top of the auxiliary plate, and anti-slip pads fixedly connected to the ends of the auxiliary plate and the clamping plate that are close to each other.

[0012] Furthermore, the bottom of the telescopic rod extends to below the bottom of the rotating frame, and the top of the threaded rod passes through the clamping plate and extends to the top outer end of the clamping plate.

[0013] Furthermore, the surface of the threaded rod is threadedly connected to the inner wall of the clamping plate, and the bottom of the vertical plate penetrates through the auxiliary plate and extends to the bottom outer end of the auxiliary plate.

[0014] Furthermore, the stabilizing component includes a support rod, the end of which is fixedly connected to the surface of the limiting plate. A pressing plate is rotatably connected to the end of the support rod away from the limiting plate. A sliding frame is hinged to the end of the pressing plate away from the support rod. A base plate is fixedly connected to the bottom of the fixed plate. A sliding hole plate is fixedly connected to the bottom of the base plate.

[0015] Furthermore, the end of the extrusion plate away from the support rod is inclined upward, the inner wall of the sliding frame is slidably connected to the surface of the sliding hole plate, the inner wall of the sliding frame extends into the interior of the sliding hole plate, the surface of the elastic rod is slidably connected to the inner wall of the sliding hole plate, and the end of the elastic rod away from the sliding frame extends to the outer end of the sliding hole plate.

[0016] Furthermore, the end of the pressure plate away from the elastic rod contacts the surface of the triangular contact frame, the top of the spring is fixedly connected to the bottom of the circular hole plate, and the top of the blocking pad is horizontally positioned with the top of the fixing plate.

[0017] The present invention has the following beneficial effects:

[0018] This invention places the laptop on top of the mounting plate, with the bottom of the laptop contacting the protective pad. The protective pad increases the friction between the mounting plate and the laptop, preventing the laptop from slipping during use. When the keyboard angle needs to be adjusted, the resistance component is pushed apart, causing the mounting plate to rotate downwards. The angle of the mounting plate is used to adjust the keyboard angle. As the mounting plate rotates, it drives the first gear to rotate via a rotating rod. The first gear, in turn, drives the second gear to rotate. The bottom of the feet contacts the top of the desktop during installation. As the second gear rotates, it moves upwards by engaging with a toothed plate. This engagement of the second gear and the toothed plate adjusts the height of the mounting plate, allowing the user to operate the laptop keyboard more comfortably.

[0019] When the height of the fixing plate needs to be adjusted, the cross bar is pushed to slide on the surface of the rectangular bar and separate from the inner wall of the cross groove bar. At this time, the fixing plate can be adjusted in angle. Inside the semi-circular spring, a triangular plate is provided that contacts the inner wall of the resistance groove. When the rotating rod rotates, it will drive the cross groove bar to rotate and squeeze the triangular plate through the resistance groove, increasing the resistance of the fixing plate when rotating. This prevents the fixing plate from rotating rapidly due to the weight of the laptop, which could cause the laptop to fall. After the angle of the fixing plate is adjusted, the cross bar is inserted into the cross groove bar to fix it, preventing the fixing plate from protruding and rotating when the user operates the laptop, thus improving the stability of the fixing plate in supporting the laptop.

[0020] When the rotating frame needs to be fixed, the threaded rod is twisted to rotate. The threaded rod, through its threaded connection with the clamping plate, pushes the auxiliary plate downward. After the bottom of the clamping plate is placed on the top of the table, the threaded rod is twisted to reverse. At this time, the threaded rod will push the auxiliary plate upward to contact the bottom of the table, thus completing the installation of the rotating frame. Simply twisting the threaded rod can fix the rotating frame on the table, improving its ease of installation. The clamping plate is connected to the right-angle plate through a telescopic rod. When the height of the rotating frame is adjusted, the telescopic rod will be pulled to extend. The telescopic rod is used to limit the rotation frame, improving the stability of the rotating frame during operation.

[0021] When the fixed plate of this invention rotates, it presses the extrusion plate through the sliding hole plate, so that the extrusion plate can push the sliding frame to slide on the surface of the sliding hole plate. When the sliding frame moves, it pushes the elastic rod to move to the outer end of the sliding hole plate. When the elastic rod moves, it pushes the pressure plate to press the triangular contact frame, so that the pressure plate can push the triangular contact frame to move upward. When the triangular contact frame moves upward, it pushes the blocking pad to move upward through the connection between the moving rod and the reinforcing frame, so that the blocking pad can move to the top outer end of the fixed plate. At this time, the blocking pad will contact the end of the laptop. The blocking pad is used to limit the laptop and prevent the laptop keyboard from slipping due to tilting after the angle adjustment is completed.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
