Technical Field

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

[0002] The production and sales of computer stands in China are relatively mature, with many brands and models available on the market. In terms of science and technology, some large enterprises and research institutions have also begun to focus on the ergonomic design and material selection of computer stands and have conducted related research. However, with the popularization of remote work and online learning, people's demand for computer stands is increasing to improve the comfort of working and studying at home.

[0003] Traditional computer stands are adjustable in angle and foldable, but this means that different users need to readjust the angle each time they use the stand. Furthermore, existing computer stands cannot automatically adjust to the appropriate angle based on the user's sitting posture, requiring frequent readjustment.

[0004] Therefore, it is necessary to propose an adaptive computer stand to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive adjustable computer stand. Through the cooperation between the internal parts of the fixing mechanism and the internal parts of the adjusting mechanism, the microcontroller terminal can process the detection signal of the ultrasonic ranging module and drive the servo motor to rotate and adjust the adjusting bracket and the mounting bracket. This allows for the adjustment of the appropriate height and angle between the user and the computer screen, reducing the risk of injury. This solves the problem in existing technologies where different users need to readjust the support angle when using the stand, and existing computer stands cannot automatically adjust the angle according to the user's sitting posture, requiring frequent adjustments by the user.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive adjustable computer stand, comprising a mounting base, a plurality of adjustable brackets being mechanically connected to the top of the mounting base, a mounting bracket being mechanically connected to the top of the adjustable brackets, a fixing mechanism being threadedly connected to the bottom of the mounting base and located at the bottom of the mounting bracket, and an adjusting mechanism being installed and fixed on the inner wall of the plurality of adjustable brackets and extending into the interior of the adjusting brackets.

[0007] The fixing mechanism includes a threaded rod, which is threaded to the bottom end of the mounting base and extends into the interior of the mounting base. A connecting clamp is machined at the top end of the threaded rod and is slidably connected to the interior of the mounting base. A horizontal bracket is machined at the bottom end of the mounting bracket and is level with the computer screen on the mounting bracket. An ultrasonic ranging module is fixed to the bottom surface of the horizontal bracket by bolts.

[0008] The adjustment mechanism includes a drive servo motor, which is mechanically connected inside the adjustment bracket and extends through to the inside of another adjustment bracket. Multiple microcontroller terminals are installed and fixed at the rotatable connection between the adjustment bracket and the other adjustment bracket, and are located on the surface of the adjustment bracket. Infrared sensors are mechanically installed inside the adjustment bracket and are respectively connected to the microcontroller terminals and the drive servo motor via flexible cables.

[0009] Preferably, the adjustment mechanism further includes a DC motor, which is installed and fixed inside the drive servo. The output end of the DC motor is mechanically connected to a transmission gear. A reduction gearbox is installed and fixed on one side of the transmission gear and is located inside the drive servo. The output end of the reduction gearbox is rotatably connected to a transmission shaft, which passes through the drive servo to the interior of the adjustment bracket.

[0010] Preferably, the plurality of adjusting brackets can rotate at an angle of 180 degrees, and the rotating connection of the plurality of adjusting brackets is mechanically machined with a limit block.

[0011] Preferably, the mounting base is C-shaped, and the bottom end of the mounting base has a threaded groove that matches the threaded rod, and the inner wall of the mounting base has an adjustment groove that matches the connecting clamp.

[0012] Preferably, the ultrasonic ranging module is model HC-SR04 and includes two ultrasonic sensors. The ultrasonic ranging module consists of an ultrasonic transmitter and a receiver, and is connected to the microcontroller terminal signal via a flexible cable.

[0013] Preferably, the DC motor is connected to the microcontroller terminal via a cable signal connection, the transmission gear meshes with the gears inside the reduction gearbox, and the transmission shaft is connected to multiple adjusting brackets and a drive servo motor via bearings.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By attaching the mounting base to the computer desktop and rotating the threaded rod, the rotation of the threaded rod causes the connecting clamp to slide on the inner wall of the mounting base, thus clamping and fixing the mounting base and connecting clamp on the computer desktop. This positions the adjustment bracket and mounting bracket above the computer desktop. Simultaneously, the ultrasonic ranging module is fixed to the horizontal bracket with bolts. When the user is using the computer, the ultrasonic ranging module below the computer transmits detection signals to the microcontroller terminal through the ultrasonic transmitter and receiver. The microcontroller terminal then transmits signals to drive the servo motor to rotate. The rotation of the servo motor causes the angle and height between the multiple adjustment brackets and the mounting bracket to be adjusted, thus ensuring that the height and angle of the computer screen on the mounting bracket are in a comfortable position for the user, reducing the risk of injury.

[0016] 2. The microcontroller terminal transmits signals to the drive servo motor, energizing the DC motor and driving the transmission gear to rotate rapidly. The transmission gear's rotation speed is reduced by a reduction gearbox, driving the transmission shaft to rotate. The rotation of the transmission shaft can then drive the angle between multiple adjustment brackets for adjustment. The multiple adjustment brackets can rotate 180 degrees. Limit blocks are machined at the joints of the multiple adjustment brackets. When the adjustment brackets rotate, infrared sensors detect the limit blocks on the adjustment brackets. When the limit blocks reach their extreme positions, the infrared sensors can promptly transmit signals to the microcontroller terminal, thus preventing collisions between the multiple adjustment brackets due to angle adjustment rotation.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4 An adaptive adjustable computer stand is shown, including a mounting base 1, a plurality of adjustable brackets 101 are mechanically connected to the top of the mounting base 1, a mounting bracket 102 is mechanically connected to the top of the adjustable brackets 101, a fixing mechanism 2 is threadedly connected to the bottom of the mounting base 1 and is located at the bottom of the mounting bracket 102, and an adjusting mechanism 3 is installed and fixed on the inner wall of the plurality of adjustable brackets 101 and extends into the interior of the adjustable brackets 101.

[0026] The fixing mechanism 2 includes a threaded rod 201, which is threaded to the bottom end of the mounting base 1 and extends into the interior of the mounting base 1. A connecting clamp 202 is machined at the top end of the threaded rod 201 and is slidably connected to the interior of the mounting base 1. A horizontal bracket 204 is machined at the bottom end of the mounting bracket 102 and is level with the computer screen on the mounting bracket 102. An ultrasonic ranging module 203 is fixed to the bottom surface of the horizontal bracket 204 by bolts.

[0027] The adjustment mechanism 3 includes a drive servo motor 301, which is mechanically connected to the inside of the adjustment bracket 101 and extends through to the inside of another adjustment bracket 101. Multiple microcontroller terminals 303 are installed and fixed at the rotatable connection between the adjustment bracket 101 and the other adjustment bracket 101, and are located on the surface of the adjustment bracket 101. An infrared sensor 302 is mechanically installed inside the adjustment bracket 101 and is connected to the microcontroller terminal 303 and the drive servo motor 301 respectively through flexible cables.

[0028] The internal components of the fixing mechanism 2 work together to facilitate the installation and fixation of the computer stand on computer desktops of different thicknesses via the mounting base 1. It also facilitates the detection of the distance between the computer screen and the user via the ultrasonic ranging module 203. The internal components of the adjustment mechanism 3 work together to facilitate the processing of the signal detected by the ultrasonic ranging module 203 by the microcontroller terminal 303, and to enable the drive servo motor 301 to rotate and adjust the adjustment bracket 101 and the mounting bracket 102. This allows for the adjustment of the appropriate height and angle between the user and the computer screen, reducing the risk of injury.

[0029] Refer to the instruction manual appendix Figure 1-4 The adjustment mechanism 3 also includes a DC motor 304, which is installed and fixed inside the drive servo motor 301. The output end of the DC motor 304 is mechanically connected to a transmission gear 305. A reduction gearbox 306 is installed and fixed on one side of the transmission gear 305 and is located inside the drive servo motor 301. The output end of the reduction gearbox 306 is rotatably connected to a transmission shaft 307, which passes through the drive servo motor 301 to the interior of the adjustment bracket 101. Through the mutual cooperation between the internal parts of the adjustment mechanism 3, the drive servo motor 301 can drive the multiple adjustment brackets 101 and the mounting bracket 102 to adjust the angle and height through the transmission shaft 307.

[0030] Refer to the instruction manual appendix Figure 1-4 Multiple adjustable brackets 101 can rotate 180 degrees. The rotating connection of multiple adjustable brackets 101 is machined with a limit block. The 180-degree rotation between multiple adjustable brackets 101 and the machined limit block at the rotating connection of multiple adjustable brackets 101 facilitate the angular rotation between multiple adjustable brackets 101, so that the height and angle of the mounting bracket 102 are in a comfortable state with the user.

[0031] Refer to the instruction manual appendix Figure 1-4 The mounting base 1 is C-shaped, and its bottom end has a threaded groove that matches the threaded rod 201. The inner wall of the mounting base 1 has an adjustment groove that matches the connecting clamp 202. By having the mounting base 1 in a C-shape, and the bottom end having a threaded groove that matches the threaded rod 201, and the inner wall having an adjustment groove that matches the connecting clamp 202, the mounting base 1 and the connecting clamp 202 can cooperate to complete the clamping connection on computer desktops of different thicknesses.

[0032] Refer to the instruction manual appendix Figure 1-4The ultrasonic ranging module 203, model HC-SR04, contains two ultrasonic sensors. It consists of an ultrasonic transmitter and a receiver, and is connected to the microcontroller terminal 303 via a flexible cable. This connection facilitates the output of the detected signal from the ultrasonic ranging module 203 to the microcontroller terminal 303.

[0033] Refer to the instruction manual appendix Figure 1-4 The DC motor 304 is connected to the microcontroller terminal 303 via a cable signal connection. The transmission gear 305 meshes with the gears inside the reduction gearbox 306. The transmission shaft 307 is rotatably connected to multiple adjustment brackets 101 and drive servo motor 301 via bearings. The transmission gear 305 meshes with the gears inside the reduction gearbox 306. The transmission shaft 307 is rotatably connected to multiple adjustment brackets 101 and drive servo motor 301 via bearings. After the transmission gear 305 rotates and is decelerated by the reduction gearbox 306, the transmission shaft 307 drives the adjustment bracket 101 to rotate at a stable and slow angle, thereby reducing the occurrence of collisions between multiple adjustment brackets 101 due to rapid rotation.

[0034] The working principle of this practical application is as follows:

[0035] Refer to the instruction manual appendix Figure 1-4 By attaching the mounting base 1 to the computer desktop and rotating the threaded rod 201, the rotation of the threaded rod 201 causes the connecting clamp 202 to slide on the inner wall of the mounting base 1, thus clamping and fixing the mounting base 1 and the connecting clamp 202 on the computer desktop. This allows the adjustment bracket 101 and the mounting bracket 102 to be positioned above the computer desktop. At the same time, the ultrasonic ranging module 203 is fixed to the horizontal bracket 204 with bolts. When the user is using the computer, the ultrasonic ranging module 203 below the computer transmits the detection signal to the microcontroller terminal 303 through the ultrasonic transmitter and receiver. The microcontroller terminal 303 then transmits a signal to drive the servo motor 301 to rotate. The rotation of the servo motor 301 causes the angle and height between the multiple adjustment brackets 101 and the mounting bracket 102 to be adjusted, thus ensuring that the height and angle of the computer screen on the mounting bracket 102 are in a comfortable position for the user and reducing the risk of injury.

[0036] Refer to the instruction manual appendix Figure 1-4The microcontroller terminal 303 transmits a signal to the drive servo motor 301, which powers the DC motor 304 and drives the transmission gear 305 to rotate rapidly. The transmission gear 305's rotation speed is reduced by the reduction gearbox 306, which in turn drives the transmission shaft 307 to rotate. The rotation of the transmission shaft 307 can drive the angle between multiple adjustment brackets 101 to be adjusted. The multiple adjustment brackets 101 can rotate 180 degrees. Limit blocks are machined at the joints of the multiple adjustment brackets 101. When the adjustment brackets 101 rotate, the infrared sensor 302 detects the limit blocks on the adjustment brackets 101. When the limit blocks reach their limit positions, the infrared sensor 302 can transmit a signal to the microcontroller terminal 303 in time, thus preventing collisions between the multiple adjustment brackets 101 due to angle adjustment rotation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
