Description

Technical Field

[0001] This utility model belongs to the technical field of fitness auxiliary equipment, specifically an adjustable bracket suitable for human posture recognition and detection devices. Background Technology

[0002] Because everyone's height, weight, and skeletal structure vary significantly, their posture characteristics are also independent, specific, and unique. Human posture measurement captures human movements and postures to detect, track, and identify human behavior, distinguishing specific actions of the human body in dynamic images. In recent years, computer vision technology based on artificial intelligence has developed rapidly, and human posture detection is one of the most challenging research directions in the field of computer vision, widely used in human-computer interaction, intelligent monitoring, virtual reality, and human behavior analysis. With the increasing popularity of fitness in daily life, using appropriate human posture detection equipment to capture images of human postures during exercise to assist in guiding workouts has become an application of human posture detection.

[0003] In existing technologies, detection devices for human posture recognition mainly focus on image or video acquisition at fixed angles, such as the "Human Posture Recognition Method and Device" with authorization announcement number CN109657631B. However, in fitness scenarios, the support device needs to enable the human posture recognition detection device to acquire images or videos of the moving human body from different angles and display fitness information. Yet, corresponding support device designs are rarely seen in existing human posture recognition devices. Common monitor adjustment stands mostly rely on manual adjustment of angle and height, such as the "An LED Display Adjustment Stand" with authorization announcement number CN222597245U. During fitness, the operation and attention to the human posture recognition device need to be minimized to maintain the continuity of fitness movements; therefore, improvements to the support equipment for human posture recognition devices are necessary.

[0036] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto:

[0037] Example 1: An adjustable bracket suitable for a human posture recognition and detection device, such as... Figure 1-6 As shown, it includes a clamping base, a support device, and a motion detection device.

[0038] The clamping base is made of aluminum alloy and includes a nut fastener 1, a T-bolt fastener 2, a C-shaped clamp 3, and a supporting aluminum tube 11. The lower end of the supporting aluminum tube 11 is fixedly connected to the top of the C-shaped clamp 3 by welding or other methods, while the upper part is used to connect the support device. The bolt shank of the T-bolt fastener 2 passes downward through the C-shaped clamp 3. The nut fastener 1 is located below the C-shaped clamp 3 and is threadedly connected to the T-bolt fastener 2. The head of the T-bolt fastener 2 is disc-shaped and located inside the C-shaped clamp 3, forming a pair of clamping surfaces with an adjustable distance between them. When fixing the device, the C-shaped clamp 3 is fastened to the edge of the table, the T-bolt fastener 2 is pressed against the tabletop from bottom to top, and the nut fastener 1 is screwed onto the T-bolt fastener 2 until the C-shaped clamp 3 is in the limit position, so that the T-bolt fastener 2 and the C-shaped clamp 3 cooperate to clamp the tabletop, thereby fixing the center of gravity of the entire device.

[0039] The support device includes a Z-shaped support arm, a transition column 5, a suspended support arm 6, and a self-locking gas spring 13. The Z-shaped support arm is a three-fold metal tube in a "Z" shape, vertically arranged. The middle of the Z-shaped support arm has a diagonal beam 41. One end of the diagonal beam 41 is fixedly connected to a vertical second hollow aluminum tube 42 for connecting the transition column 5. The other end of the diagonal beam 41 is fixedly connected to a first hollow aluminum tube 43. A first rotating column 44 is embedded within the first hollow aluminum tube 43. The first rotating column 44 is fixedly connected to the first hollow aluminum tube 43 and extends downwards to be inserted into the support aluminum tube 11. Figure 2 As shown. With the first rotating column 44 as the pivot, the Z-type support arm can rotate 180° counterclockwise or clockwise on the horizontal plane. Below the inclined beam 41 in the middle of the Z-type support arm, a first cable routing groove 45 is provided close to the inclined beam 41. The first cable routing groove 45 is a metal pipe that is fixedly connected to the inclined beam 41 by welding or other means, and is used to hide the signal lines and power lines connecting the display screen and the servo motor 8.

[0040] Adapter post 5 is used to connect the hoverable support arm 6 and the Z-type support arm, such as Figure 3 As shown, the structure includes a lower adapter column body and an upper fork lug 52. The adapter column body includes a third hollow aluminum tube 53, within which a second rotating column 54 is embedded. The second rotating column 54 is fixedly connected to the third hollow aluminum tube 53 and extends downwards for insertion into a second hollow aluminum tube 42. A threaded hole is provided on the second hollow aluminum tube 42. After the second rotating column 54 is inserted into the second hollow aluminum tube 42, a locking screw is used to lock the adapter column 54 and the Z-type support arm together, and the structure is further strengthened by its own weight.

[0041] The fork lug 52 includes two parallel trapezoidal lugs. The gap between the trapezoidal lugs is used to insert the self-locking gas spring 13 and for wiring. The lower part of the trapezoidal lug is fixedly connected to the adapter column body (third hollow aluminum tube 53). Each trapezoidal lug has two screw holes at different positions. The upper screw hole is used to connect and fix the self-locking gas spring 13, and the lower screw hole is used to connect and fix the suspension bracket arm 6.

[0042] The hovering support arm 6 includes an upper cover 6-1, a lower cover 6-2, and a second cable routing channel 6-3, such as... Figure 4As shown. Both the upper cover 6-1 and the lower cover 6-2 of the support arm are U-shaped. The U-shaped openings of the upper cover 6-1 and the lower cover 6-2 of the support arm are opposite each other and are detachably connected. For example, there are a pair of screw holes at the bottom of the upper cover 6-1 and the top of the lower cover 6-2, which are connected as a whole by screws. The cavity formed by the upper cover 6-1 and the lower cover 6-2 of the support arm is used to house the self-locking gas spring 13. The second wiring channel 6-3 is a hollow metal tube, which is fixedly connected to the bottom of the lower cover 6-2 of the support arm by welding or other means to hide the signal lines and power lines of the display screen and the servo motor 8.

[0043] Each of the two ends of the upper cover 6-1 and lower cover 6-2 of the support arm has a pair of screw holes, that is, one screw hole is opened on each of the two groove walls on the left side of the lower cover 6-2. The left end of the self-locking gas spring 13 is inserted into the fork lug 52 (between the two trapezoidal lugs) and is hinged to the fork lug 52 by bolts, nuts or pins. One screw hole is opened on each of the two groove walls on the right side of the upper cover 6-1 of the support arm for connecting the self-locking gas spring 13 and the motor connector 7, such as... Figure 5 As shown.

[0044] The motion detection device includes a motor connector 7, a servo motor 8, a screen connector 12, and a display control unit. The motor connector 7 has a groove at its tail with screw holes within it. The tail of the motor connector 7 (the grooved portion) is located within the hoverable support arm 6 (i.e., the space enclosed by the upper cover 6-1 and the lower cover 6-2 of the support arm). The right end of the self-locking gas spring 13, the tail of the motor connector 7, and the right side of the upper cover 6-1 are hinged together by the same bolt, nut, or pin. When the self-locking gas spring 13 is in a horizontal position, the display screen is in its initial position. When the display screen is adjusted up and down, the self-locking gas spring 13 extends and retracts, changing its length and generating a supporting force along the hoverable support arm 6. Because the self-locking gas spring 13 can bear a large load, the hoverable support arm 6 can achieve a pitch angle within a range of ±60° while ensuring load hovering.

[0045] The head of the motor connector 7 is located outside the hovering support arm 6 and has a horizontal through hole. The servo motor 8 is located on one side of the motor connector 7. The mating surfaces of the motor connector 7 and the servo motor 8 each have three threaded through holes, and three bolts are used to fit and fix the servo motor 8 and the motor connector 7 together.

[0046] The motor shaft of the servo motor 8 passes laterally through the through hole of the motor connector 7 and extends to the other side of the motor connector 7. It is connected to the screen connector 12 through the rotating shaft sleeve 10, as shown below. Figure 6As shown. The rotating sleeve 10 includes a sleeve body and a connecting block. The connecting block is located on the side wall of the sleeve body and is fixedly connected to the sleeve body. The sleeve body is sleeved on the motor shaft of the servo motor 8, and the relative fixation with the motor shaft is achieved through negative tolerance fit. The connecting block is used to connect with the screen connector 12 and drive the screen connector 12 to tilt and rotate.

[0047] The screen connector 12 is made of aluminum alloy and includes a screen connector plate 110 and a pair of hinge connecting ears 111, which are fixedly connected to the screen connector plate 110. The screen connector plate 110 has a concave structure on each of its four sides, forming a four-lobed shape. This design reduces the overall weight of the screen connector 12, ensuring support for the display screen while maximizing material savings. Each of the four lobes of the screen connector 12 has a screw hole for fixing it to the display screen using screws.

[0048] A pair of hinge connecting ears 111 are arranged side by side, and a connecting block on the hinge sleeve 10 is located between the hinge connecting ears 111 and is fixedly connected to the hinge connecting ears 111. The hinge sleeve 10 is used to prevent interference between the screen connector 12 and the support device when it rotates.

[0049] The display control unit includes a display screen with a camera and an STM32 microcontroller. The STM32 microcontroller can be the STM32F407, a high-performance 32-bit microcontroller based on the ARM Cortex-M4 core from STMicroelectronics. It is connected to the servo motor 8 to control the start, stop, and rotation angle of the servo motor 8. The rotating shaft sleeve 10 follows the angle control of the servo motor 8 to realize the change of pitch angle to adapt to different viewing angle requirements. The microcontroller control of the servo motor is an existing technology, for example, in "Sang Yong, Li Fengtao, Dai Yuebang, Duan Fuhai, Wang Yajie. Design of STM32 Microcontroller Control System for Servo Motors [J]. Mechanical and Electrical Engineering Technology, 2015, 44(11):65-72".

[0050] A display screen with a camera is connected to an STM32 microcontroller to display video data sent by a host computer. Image data captured by the camera is transmitted to the host computer via the STM32 microcontroller. The STM32 microcontroller is mounted on the back of the display screen and is connected to the host computer via a network module (e.g., an ESP32S2 module). The host computer sends control signals to the STM32 microcontroller via a wireless network, thereby controlling the start, stop, and rotation angle of the servo motor 8. It should be noted that the host computer's function of receiving image data and recognizing human posture in the images is not within the scope of this utility model. For example, the steps of a human posture recognition method can be implemented by the "Method and Device for Human Posture Recognition" disclosed in CN109657631B, which includes an electronic device, a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program.

[0051] The specific method of using this utility model is as follows:

[0052] 1. Manual adjustment before exercise

[0053] Before starting the exercise, users can manually adjust the components according to their own needs:

[0054] 1.1 Users can adjust the rotation angle of the Z-type bracket arm on the horizontal plane in a counterclockwise or clockwise direction to adjust the horizontal position of the display screen to adapt to different usage scenarios and user viewing angles.

[0055] 1.2 When the user moves the hovering support arm 6 up or down, the self-locking gas spring 13 extends or shortens, simultaneously generating a supporting force along the hovering support arm 6 on the screen, thereby achieving the hovering function of the display screen in the vertical direction to obtain the optimal angle.

[0056] 2. Automatic adjustment during exercise

[0057] The display screen with a camera captures image information of the user during exercise and sends it to the host computer.

[0058] The host computer starts the servo motor 8 through the STM32 microcontroller. The servo motor 8 drives the display screen to rotate through the rotating shaft sleeve 10 and the screen connector 12 to make precise adjustments to the tilt angle.

[0059] Finally, it should be noted that the above examples are merely a few specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
