Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, and in particular to a treadmill that adaptively adjusts the height of the display screen based on the user's height. Background Technology

[0002] As mainstream commercial and home fitness equipment, treadmills feature a front display screen as their core interactive component. This screen primarily displays data such as exercise duration, speed, and calorie consumption, while also supporting functions like video playback and course instruction. It directly impacts the user's information acquisition efficiency and overall experience during exercise. With increasing user demands for personalized and convenient fitness equipment, the need for height-adjustable displays for users of different heights (such as children, adults, and family members with significant height differences) is becoming increasingly prominent. For example, Chinese patent CN223055051U proposes a multi-directionally adjustable treadmill screen, comprising four main components: the treadmill body, a height adjustment assembly, a U-shaped handrail support, and an adjustable display screen. Height adjustment relies on a structure design using a support rod, an adjustment sleeve, and tightening bolts. By loosening and tightening the bolts, the adjustment sleeve slides along the support rod. After manually adjusting to the target height, the bolts are tightened to secure it. The adjustment precision is in 5-8cm increments. However, the existing adjustment devices on treadmill displays have the following limitations and safety hazards: low adjustment accuracy, requiring repeated adjustments when there is a deviation; users need to pause running, loosen bolts, manually push the support to adjust the height, tighten bolts, and resume exercise only after confirming that there is no looseness. During exercise, the human body is in dynamic balance, and manual operation not only interrupts the exercise rhythm but also easily leads to loss of balance due to distraction, posing a risk of falling, which contradicts users' demand for a convenient and safe exercise experience.

[0003] This invention proposes a treadmill that automatically adjusts the display screen height based on the user's height. By combining a height detection module and a lifting drive mechanism, the automatic adjustment of the display screen height is achieved, avoiding the problems of low adjustment accuracy, safety hazards, and exercise interruption caused by manual adjustment of the display screen height in the prior art. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a treadmill that adaptively adjusts the height of the display screen based on the user's height.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A treadmill with an adaptive display screen height adjustment based on user height includes a treadmill body, a display screen, an adjustment module, a height detection module, and an MCU control module. The adjustment module includes a lifting drive mechanism. The treadmill body includes a mounting frame and a running board. The mounting frame is located at one end of the running board. The fixed end of the lifting drive mechanism is fixedly mounted on the mounting frame, and the movable end of the lifting drive mechanism is fixedly connected to the display screen. The height detection module is installed on the upper part of the mounting frame. The angle bisector of the detection angle of the height detection module is inclined towards the running board, and the lower boundary line of the detection angle of the height detection module intersects with the running board. The upper boundary line of the detection angle of the height detection module is set higher than the horizontal line where the height detection module is located. The MCU control module is electrically connected to both the height detection module and the lifting drive mechanism, and is used to control the lifting drive mechanism to adjust the height of the display screen according to the user's height parameters collected by the height detection module.

[0006] Preferably, the angle between the bisector of the height detection module and the horizontal line is in the range of 20° to 30°.

[0007] Preferably, the detection angle of the height detection module is greater than or equal to 60°.

[0008] Preferably, the treadmill also includes a voice module and an input module. The main body of the treadmill also includes two handrails. The voice module and the input module are installed in the middle of the handrails and are electrically connected to the MCU control module respectively. The two handrails are located on both sides of the running board and are fixedly connected to the mounting frame.

[0009] Preferably, the adjustment module also includes a moving platform, and a display mounting plate is provided on the side of the display screen facing the mounting frame. The moving platform is fixedly connected to the display mounting plate and fixedly connected to the movable end of the lifting drive mechanism.

[0010] Preferably, the adjustment module also includes a limit mechanism, which includes an upper limit switch, a lower limit switch, and a trigger stop. The upper limit switch and the lower limit switch are respectively installed on the upper and lower parts of the lifting drive mechanism and are electrically connected to the MCU control module. The trigger stop is installed on the moving platform. When the lifting drive mechanism drives the display screen to the highest limit position or to the lowest limit position, the trigger stop contacts the upper limit switch or the lower limit switch to trigger an overtravel protection signal. The MCU control module cuts off the power supply to the lifting drive mechanism according to the overtravel protection signal, so that the lifting drive mechanism stops working.

[0011] Preferably, the height detection module uses a photoelectric sensor or an ultrasonic sensor.

[0012] Preferably, the treadmill body also includes a mounting frame housing, with a height detection module embedded in the upper part of the mounting frame housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The MCU control module of the treadmill proposed in this utility model is electrically connected to the height detection module and the lifting drive mechanism respectively. It can control the lifting drive mechanism to move the display screen up and down according to the height parameters of the user collected by the height detection module, so as to automatically adjust the height of the display screen, improve the user's viewing experience of the display screen, and solve the problems of low adjustment accuracy, safety hazards and exercise interruption in the prior art of manually adjusting the height of the display screen.

[0014] (2) The treadmill proposed in this utility model has a lifting drive mechanism to drive the display screen to move up and down, which has higher adjustment accuracy of the display screen height and no bolt or damping loss, thereby extending the service life of the treadmill and reducing the maintenance cost of the treadmill.

[0015] (3) The treadmill proposed in this utility model is based on the user's height adaptive adjustment of the display screen height. By limiting the installation angle of the height detection module, the detection wave emitted by the height detection module can effectively cover the user's shoulder area, thereby collecting the distance data of the user's standing point above the running board as the user's height parameter, avoiding the instability of the collected data caused by factors such as hair when directly detecting the head.

[0016] (4) The treadmill proposed in this utility model that adaptively adjusts the height of the display screen based on the user's height is equipped with a limit mechanism to avoid damage caused by excessive adjustment of the display screen, thereby improving the safety of the treadmill.

[0017] (5) The treadmill proposed in this utility model that adjusts the height of the display screen based on the user's height also has a voice module and an input module on the handrail, so that the MCU control module can control the lifting drive mechanism to adjust the height of the display screen through voice commands or input commands. Furthermore, by setting the voice module in the middle of the handrail, the voice acquisition distance is less than the preset distance, so as to ensure the accuracy of voice command acquisition.

[0020] refer to Figures 1 to 8This application proposes a treadmill that adaptively adjusts the height of the display screen based on the user's height. The treadmill includes a main body 1, a display screen 2, an adjustment module, a height detection module 4, an MCU control module 5, a voice module 6, and an input module 7. The adjustment module includes a lifting drive mechanism 31. The main body 1 includes a mounting frame 11, a running board 12, and two handrails 13. The two handrails 13 are located on both sides of the running board 12 and are fixedly connected to the mounting frame 11. The fixed end of the lifting drive mechanism 31 is fixedly mounted on the mounting frame 11, and the movable end of the lifting drive mechanism 31 is fixedly connected to the display screen 2. The height detection module 4 is installed on the upper part of the mounting frame 11, and the voice module 6 and input module 7 are installed in the middle of the handrails 13. The MCU control module 5 is deployed on either the handrails 13 or the display screen 2, and is electrically connected to the height detection module 4, the lifting drive mechanism 31, the voice module 6, and the input module 7, respectively. In the embodiments of this application, the lifting drive mechanism 31 adopts the existing lead screw module or electric push rod, which will not be described in detail here; the voice module 6 integrates a voice recognition chip, an electret microphone and a two-stage noise reduction circuit. The microphone extends to the top middle position of the handrail 13 through a flexible tube to ensure that the voice collection distance is less than the preset distance. In the embodiments of this application, the preset distance is 50cm to ensure the accuracy of voice command collection.

[0021] In the embodiments of this application, reference is made to Figures 1 to 4 The height detection module 4 is used to collect distance data at a specific height above the user's standing point on the running board 12 as the user's height parameter and transmit it to the MCU control module 5; the voice module 6 is used to collect voice commands issued by the user and transmit them to the MCU control module 5, as well as voice broadcasts, such as collecting voice commands issued by the user to raise the display screen 2 by 3cm, the height parameter, playing display screen 2 adjustment prompts, playing prompts to prevent overtravel adjustment, and playing prompts that the command is not recognized and should be re-entered, etc.; the input module 7 is used to collect commands about the height adjustment of the display screen 2 manually input by the user through the touch screen or physical buttons and transmit them to the MCU control module 5, such as the height, the ideal height of the display screen 2, and the command of the display screen 2 height adjustment button + / -, etc., entered by the user on the input module 7; the MCU control module 5 is used to receive the parameters or commands collected by the height detection module 4, the voice module 6 and the input module 7, calculate the corresponding optimal height of the display screen 2 according to the user's height parameter collected by the height detection module 4, and control the lifting drive mechanism 31 to work to adjust the height of the display screen 2.

[0022] The MCU control module 5 of this application proposes a treadmill with a height-adaptive display screen height adjustment system based on user height. This module is electrically connected to the height detection module 4 and the lifting drive mechanism 31. Based on the user's height parameters collected by the height detection module 4, the lifting drive mechanism 31 controls the display screen 2 to move up and down, automatically adjusting its height. This improves the user's viewing experience and allows for height adjustment without interrupting exercise, enhancing exercise continuity. It solves the problems of low adjustment accuracy, safety hazards, and exercise interruption associated with manual height adjustment in existing technologies. Furthermore, by using the lifting drive mechanism 31 to move the display screen 2, and employing a lead screw module or electric push rod, the height of the display screen 2 can be continuously adjusted with higher accuracy and without bolt or damping losses, thereby extending the treadmill's lifespan and reducing maintenance costs.

[0023] In a specific embodiment, the angle bisector 41 of the detection angle of the height detection module 4 is inclined towards the running board 12, and the lower boundary line 43 of the detection angle of the height detection module 4 intersects with the running board 12. The upper boundary line 42 of the detection angle of the height detection module 4 is set higher than the horizontal line 44 where the height detection module 4 is located. Specifically, the angle between the angle bisector 41 of the detection angle of the height detection module 4 and the horizontal line 44 ranges from 20° to 30°. The detection angle of the height detection module 4 is greater than or equal to 60°. (Reference) Figure 3 The angle θ between the angle bisector 41 and the horizontal line 44 of the height detection module 4 is 20°, and the detection angle FOV is 60°. The detection wave emitted by the height detection module 4 can effectively cover the user's shoulder area; in another embodiment, referencing Figure 4 The angle θ between the angle bisector 41 and the horizontal line 44 of the height detection module 4 is 30°, and the field of view (FOV) of the detection angle is 65°. The detection wave emitted by the height detection module 4 can effectively cover the user's shoulder area. In the embodiments of this application, the treadmill body 1 also includes a mounting frame shell 14, and the height detection module 4 is embedded in the upper part of the mounting frame shell 14, making it less susceptible to damage from collisions. Through the installation angle design of the height detection module 4, the detection wave emitted by the height detection module 4 can effectively cover the user's shoulder area, thereby obtaining distance data at a specific height above the user's standing point on the running board 12, to obtain effective height parameters of the user, avoiding the instability of data obtained by directly detecting the head due to factors such as hair.

[0024] In a specific embodiment, refer to Figure 5The adjustment module also includes a moving platform 32. A display mounting plate 21 is provided on the side of the display screen 2 facing the mounting frame 11. The moving platform 32 is fixedly connected to the display mounting plate 21 and to the movable end of the lifting drive mechanism 31. In this embodiment, the display screen 2 is used to display treadmill parameters, exercise data, and video content. The side of the display screen 2 facing the mounting frame 11 is fixedly connected to one side of the display mounting plate 21 by bolts, and the other side of the display mounting plate 21 is fixedly connected to the moving platform 32 by bolts. The moving platform 32 is fixedly connected to the lead screw nut of the lifting drive mechanism 31. By setting the display mounting plate 21, the connection stability between the display screen 2 and the moving platform 32 is enhanced, preventing damage caused by uneven force on the display screen 2 during height adjustment and ensuring the stability of the display screen 2 during height adjustment.

[0025] In a specific embodiment, refer to Figures 5 to 7The adjustment module also includes a limit mechanism 33, which includes an upper limit switch 331, a lower limit switch 332, and a trigger stop 333. The upper limit switch 331 and the lower limit switch 332 are respectively installed on the upper and lower parts of the lifting drive mechanism 31 and are electrically connected to the MCU control module 5. The trigger stop 333 is installed on the moving platform 32. When the lifting drive mechanism 31 drives the display screen 2 to rise to the highest limit position or fall to the lowest limit position, the trigger stop 333 contacts the upper limit switch 331 or the lower limit switch 332 to trigger an overtravel protection signal. The MCU control module 5 cuts off the power supply to the lifting drive mechanism 31 according to the overtravel protection signal, so that the lifting drive mechanism 31 stops working and prevents the display screen 2 from overtraveling and causing damage to the treadmill. In the embodiments of this application, the working principle of the limit mechanism 33 is explained by taking the upper limit switch 331 and the lower limit switch 332 as photoelectric proximity switches of model E3F-DS30C4 as an example: the output form of the upper limit switch 331 and the lower limit switch 332 is NPN. Normally closed, the trigger stop 333 is made of metal or plastic. When the moving platform 32 rises to the highest limit position that allows the display screen 2 to reach the safe height range, the trigger stop 333 fixed to the moving platform 32 will insert between the transmitting and receiving ends of the upper limit switch 331, blocking the infrared detection beam emitted by the transmitting end. The upper limit switch 331 is triggered and sends a level change signal from normally closed to open to the MCU control module 5, i.e., an overtravel protection signal. After receiving the overtravel protection signal, the MCU control module 5 cuts off the drive current to the motor of the lifting drive mechanism 31, causing the lifting drive mechanism 31 to stop working, thereby driving the moving platform 32 and the display screen 2 to stop rising. Similarly, when the moving platform 32 descends to the lowest limit position that allows the display screen 2 to reach the safe height range, the trigger stop 333 triggers the lower limit switch 332 to send an overtravel protection signal to the MCU control module 5, so that the MCU control module 5 controls the lifting drive mechanism 31 to stop working. The present application proposes a treadmill with a height-adaptive adjustment display screen 2 based on the user's height. By setting a limit mechanism 33, the height adjustment of the display screen 2 is protected to prevent the display screen 2 from being adjusted beyond its range, thus ensuring the safe operation of the treadmill.

[0026] In a specific embodiment, the height detection module 4 employs a photoelectric sensor or an ultrasonic sensor for non-contact sensing of the user's height parameters. Specifically, the beam emitted by the emitter of the photoelectric sensor has a certain diffusion angle, which determines the range of objects it can detect. When using a photoelectric sensor as the height detection module 4, the diffusion angle of the beam emitted by the emitter of the photoelectric sensor is used as the detection angle of the height detection module 4; when using an ultrasonic sensor as the height detection module 4, the diffusion angle of the ultrasonic waves emitted by the ultrasonic sensor in space is used as the detection angle of the height detection module 4.

[0027] The following describes the usage process of a treadmill that adaptively adjusts the display screen height based on the user's height, as proposed in this application.

[0028] After the treadmill is powered on and the start switch is pressed, the power supply provides power to each module. The height detection module 4 automatically starts detection, the voice module 6 enters standby mode, and broadcasts the adjustment prompts for the display screen 2. In this embodiment, the adjustment prompt for the display screen 2 is "I will automatically adjust the optimal height of the display screen 2 for you." At the same time, the display screen 2 displays the treadmill parameters and command input prompts.

[0029] In automatic adjustment mode, the height detection module 4 transmits a probe wave to measure the distance data of the user at a specific height above the user's standing point on the running board 12 as the user's height parameter, and simultaneously feeds it back to the MCU control module 5. The MCU control module 5 calculates the corresponding optimal display screen 2 height based on the user's height parameter, and uses this optimal display screen 2 height as the target height. The MCU control module 5 then controls the lifting drive mechanism 31 to automatically adjust the height of the display screen 2 according to the target height.

[0030] In voice adjustment mode, the voice module 6 collects the user's voice command regarding the height adjustment of the display screen 2 and transmits it to the MCU control module 5. The MCU control module 5 calculates the target height based on the voice command and controls the lifting drive mechanism 31 to adjust the height of the display screen 2 accordingly. If the user needs to fine-tune the height of the display screen 2 while moving, they can also adjust it via voice command until it suits their viewing angle.

[0031] In manual adjustment mode, the user inputs the ideal height of the display screen 2 into the input module 7. The input module 7 transmits the height of the display screen 2 to the MCU control module 5. The MCU control module 5 uses the user's ideal height of the display screen 2 as the target height to control the lifting drive mechanism 31 to adjust the height of the display screen 2.

[0032] When the target height is within the safe height range of the display screen 2, the MCU control module 5 controls the lifting drive mechanism 31 to drive the display screen 2 to the target height, and then the MCU control module 5 controls the lifting drive mechanism 31 to stop working.

[0033] When the target height is outside the safe height range of the display screen 2, the lifting drive mechanism 31 drives the display screen 2 to rise to the highest limit position of the safe height range or descend to the lowest limit position of the safe height range. This triggers the baffle 333 to contact the upper limit switch 331 or the lower limit switch 332. The upper limit switch 331 or the lower limit switch 332 triggers a power-off command and transmits it to the MCU control module 5. The MCU control module 5 cuts off the power supply to the lifting drive mechanism 31, causing the lifting drive mechanism 31 to stop working and stop the display screen 2 from continuing to adjust its height to prevent damage from overtravel. At the same time, the MCU control module 5 controls the voice module 6 to issue a warning that the height of the display screen 2 has reached the maximum or minimum height to prevent overtravel adjustment.

[0034] Display screen 2 is height initialized. When the user finishes moving, the MCU control module 5 is automatically initialized and controls the lifting drive mechanism 31 to move the display screen 2 up and down to reset it to the default height.

[0035] This application proposes a treadmill with a height-adaptive display screen height adjustment based on user height. The height detection module 4 collects the user's height parameters, which control the lifting drive mechanism 31 to move the display screen 2 up and down, automatically matching the height of the display screen 2 to the user's height. This improves the adjustment accuracy of the display screen 2 and allows the user to adjust its height via voice commands during exercise, adapting the display screen 2 to the user's viewing angle. This also enhances exercise continuity and user experience, preventing distraction and interruption of exercise adjustments. Furthermore, the lifting drive mechanism 31 eliminates bolt and damping losses, extending the treadmill's lifespan and reducing maintenance costs. Additionally, a limit mechanism 33 is included to ensure the safety of the display screen 2's height adjustment, preventing over-adjustment and ensuring safe treadmill operation.

[0036] The above embodiments are only used to further illustrate the technical solution of this utility model, but this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
