Description

Technical Field

[0001] This utility model relates to the technical field of medical devices and sports training aids, and in particular to a lower limb support training weight quantification alarm device. Background Technology

[0002] Precise control of training weight is crucial in lower limb rehabilitation training and various lower limb strength training scenarios. However, current training equipment on the market has many shortcomings.

[0003] In the field of rehabilitation, patients are in the recovery phase of their physical function and require strict control of training intensity to avoid secondary injury from overtraining. However, existing rehabilitation training equipment often cannot accurately measure the weight supported by the lower limbs. Rehabilitation therapists can only rely on experience and the patient's subjective feelings to roughly judge the training intensity. This method lacks scientific basis and makes it difficult to ensure that each patient receives accurate and appropriate training. For example, for patients in the recovery period after a fracture, the initial weight supported by the lower limbs needs to be strictly controlled at a low level. If the training weight is too high, it may affect the healing of the fracture site. For patients with muscle atrophy, the training weight needs to be gradually increased according to the muscle recovery. The lack of quantitative methods makes it difficult for training to achieve the ideal effect.

[0004] Furthermore, existing training equipment has limitations in height adjustment. Most devices have a fixed height, failing to meet the needs of users of different heights, which limits the equipment's versatility and results in a poor training experience. Moreover, during training, if the training weight exceeds the safe range, the lack of an effective alarm mechanism makes it difficult for users to notice in time, further increasing the risk of injury.

[0005] In conclusion, developing a training device that can accurately measure the weight supported by the lower limbs, adjust the height, has an alarm function, and is easy to operate is of great significance for improving the effectiveness of lower limb rehabilitation training and the quality of exercise training. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, the purpose of this utility model is to propose a lower limb support training weight quantification alarm device. Through the cooperation of a pressure sensor and a microcontroller, it can accurately measure and display the lower limb support weight, which is convenient for trainees to formulate scientific training plans, help rehabilitation patients to train accurately and accelerate rehabilitation. Its lifting device is height-adjustable to adapt to people of different heights and has strong versatility. Moreover, when the training weight exceeds the set value, the alarm will sound an audible and visual alarm to prevent users from being injured due to excessive weight and ensure safety.

[0008] To achieve the above objectives, this utility model proposes a lower limb support training weight quantification alarm device, comprising a base plate, a lifting device, a support plate, multiple pressure sensors, an operating device, and an alarm. The lifting device includes a lifting assembly slidably mounted on the top of the base plate. The support plate is fixedly connected to the top of the lifting assembly. Multiple pressure sensors are evenly distributed on the top of the support plate for real-time monitoring of the lower limb support weight. The operating device includes a support rod and an operating panel. The support rod is fixedly mounted on one side of the top of the support plate. The operating panel is located on the top of the support rod and electrically connected to the multiple pressure sensors for receiving and processing signals from the pressure sensors. The alarm is located on the top of the operating panel and electrically connected to the operating panel, issuing an alarm signal when the monitored weight exceeds a set value.

[0009] This utility model discloses a lower limb support training weight quantification alarm device. Through the cooperation of a pressure sensor and a microcontroller, it can accurately measure and display the lower limb support weight, which is convenient for trainees to formulate scientific training plans, help rehabilitation patients to train accurately and accelerate rehabilitation. Its lifting device is height-adjustable to adapt to people of different heights, and has strong versatility. Moreover, when the training weight exceeds the set value, the alarm will sound an audible and visual alarm to prevent users from being injured due to excessive weight and ensure safety.

[0010] In addition, the lower limb support training weight quantification alarm device proposed in the above application may also have the following additional technical features:

[0011] Specifically, the lifting assembly includes four base columns, four sliding rods, four slots, and four fixing bolts. The four base columns are respectively located on the top of the base plate, with a height of four centimeters. The four sliding rods are slidably mounted on the four base columns, and each sliding rod has two holes spaced four centimeters apart on one side wall. The four slots are respectively located on one side of the four base columns. The four fixing bolts pass through the four slots and are threaded into the corresponding holes. By adjustment, the height of the support plate can be adjusted to three levels: four centimeters, eight centimeters, and twelve centimeters.

[0012] Specifically, the operation panel includes a display screen, a microcontroller, and three buttons. The display screen is fixedly mounted on one side of the top of the support rod and is used to display the current monitored weight and the set target weight. The microcontroller is located inside the display screen. The three buttons are respectively mounted on the display screen as an "increase" button, a "decrease" button, and a "confirm" button, used to set the target weight.

[0013] Specifically, the microcontroller has a built-in weight comparison algorithm. When the weight measured by the pressure sensor exceeds the set target weight, it sends an alarm signal to the alarm device.

[0014] Specifically, the alarm includes a sound alarm and a light alarm. When an alarm signal is received, it will simultaneously emit a sound and flash a light to sound the alarm.

[0015] Specifically, the microcontroller is electrically connected to multiple pressure sensors, the display screen, three buttons, and the alarm, respectively, to process signals from the pressure sensors, receive operation commands from the buttons, control the display screen to display corresponding content, and send an alarm signal to the alarm when the monitored weight exceeds a set value.

[0016] The pressure sensor used is a high-precision strain gauge pressure sensor, specifically the FSG-101 type pressure sensor that is compatible with the HX711. This model of pressure sensor has high measurement accuracy and can accurately measure minute weight changes during lower limb support, meeting the high-precision weight monitoring requirements of this device. The measurement range is 0-200kg, which can adapt to weight measurement under different training intensities.

[0017] The microcontroller used is the STC89C52. It has abundant on-chip resources, sufficient to meet the data processing and control requirements of this device. It also has ample internal storage and I / O port resources, facilitating the connection of pressure sensors, displays, buttons, and alarms, and enabling the execution of programs such as weight comparison algorithms.

[0018] The display screen uses a 1602 LCD screen. It can clearly display two lines of characters, meeting the device's requirements for displaying the current monitored weight and the set target weight. Through connection with a microcontroller, it can realize real-time data update and display, and has the advantages of low power consumption and clear display.

[0019] The audible alarm uses an active buzzer, model FMQ-2720S. This buzzer operates within a 3-5V voltage range, matching the power supply voltage of this device. It emits a loud and clear sound, effectively attracting the user's attention in the training environment and promptly reminding them that the training weight has exceeded the limit.

[0020] The light alarm uses red LEDs, such as 5mm ultra-bright red LEDs. These LEDs are bright and have a fast response time, flashing rapidly upon receiving an alarm signal to provide a striking visual alert to the user. Combined with an audible alarm, they achieve synchronized sound and light alarm functionality.

[0021] The advantages of this invention compared to existing technologies are as follows:

[0022] (1) Through the combination of pressure sensor and microcontroller, the weight supported by the lower limb can be accurately measured and displayed, enabling trainees to formulate scientific and reasonable training plans according to their own situation, improve training effect, and help doctors and rehabilitation therapists to accurately adjust the training intensity according to the patient's recovery stage and accelerate the rehabilitation process.

[0023] (2) The design of the lifting device makes the height of the device adjustable, which can accommodate users of different heights and improve the versatility of the device. Whether it is a tall adult or a short child rehabilitation patient, they can obtain a comfortable training experience by adjusting the height of the device.

[0024] (3) When the training weight exceeds the set value, the alarm will promptly issue an audible and visual alarm signal to remind the user to stop training or reduce the weight, effectively avoiding the risk of injury caused by excessive training weight and providing strong protection for the user's safety.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0032] The following description, in conjunction with the accompanying drawings, describes a lower limb support training weight quantification alarm device according to an embodiment of the present invention.

[0033] like Figures 1-3 As shown, a lower limb support training weight quantification alarm device according to an embodiment of the present invention may include a base plate 1, a lifting device 2, a support plate 3, multiple pressure sensors 4, an operating device 6, and an alarm 7.

[0034] It is understandable that, in specific implementation, this lower limb support training weight quantification alarm device operates according to the following procedure:

[0035] Preparation: Place the device on a stable surface. The base plate 1 provides stable support for the entire device. Users can adjust the height of the support plate 3 using the lifting device 2 according to their needs. The lifting component 21 in the lifting device 2 is slidably mounted on top of the base plate 1. By operating the lifting component 21, the height of the support plate 3 can be changed to accommodate different user heights.

[0036] Weight monitoring and data processing: At this time, multiple pressure sensors 4, evenly distributed on the top of the support plate 3, begin to work, monitoring the weight supported by the user's lower limbs in real time. The pressure sensors 4 convert the monitored weight signals into electrical signals and transmit them to the operating device 6. The operating panel 62 in the operating device 6 is located on the top of the support rod 61 and is electrically connected to the multiple pressure sensors 4. It is responsible for receiving and processing the signals transmitted from the pressure sensors 4.

[0037] Alarm Function Trigger: Before use, the user sets a weight setting on the control panel 62 according to their training plan or rehabilitation program. The control panel 62 continuously processes the signals from the pressure sensor 4 and compares them with the set value. Once the detected weight exceeds the set value, the control panel 62 sends a signal to the alarm 7 located on its top. Since the alarm 7 is electrically connected to the control panel 62, upon receiving the signal, the alarm 7 will sound an alarm, reminding the user that the current training weight is too heavy and needs to be adjusted.

[0038] In one embodiment of this utility model, such as Figures 1-3As shown, the lifting assembly 21 includes four base columns 211, four sliding rods 212, four slots 213 and four fixing bolts 214.

[0039] It is understandable that, in actual use of this device, when it is necessary to adjust the height of the support plate 3 to accommodate the height or training needs of different users, the operation of the lifting component 21 is involved, and its specific workflow is as follows:

[0040] Preparation for adjustment: First, the user needs to determine whether the current height of the support plate 3 meets their needs. At this point, it can be seen that four base columns 211 are respectively set on the top of the base plate 1. They are the basic support components of the entire lifting structure, and the height of each base column 211 is fixed at four centimeters.

[0041] Loosen the fixing bolts: If height adjustment is required, locate the fixing bolts 214 on one side of the base post 211. Since the four fixing bolts 214 pass through the four slots 213 and are threaded into the corresponding holes on the sliding rod 212, the user needs to rotate the fixing bolts 214 counterclockwise to gradually disengage them from the holes, thus loosening their fixing effect on the sliding rod 212. The four slots 213 are respectively located on one side of the four base posts 211, and their function is to provide movement space for the fixing bolts 214 so that the bolts can connect with the holes at different positions on the sliding rod 212.

[0042] Adjusting the height of the sliding rods: After the fixing bolts 214 are loosened, the four sliding rods 212 can slide freely on the four base posts 211 respectively. Since there are two holes spaced four centimeters apart on one side wall of the sliding rods 212, the user can select the appropriate hole position according to the required height. For example, if you want to raise the support plate 3 from four centimeters to eight centimeters, slide the sliding rods 212 upwards along the base posts 211 so that the fixing bolts 214 can be aligned with the holes on the sliding rods 212 corresponding to the eight-centimeter height.

[0043] Fixed sliding rods: After the sliding rods 212 are adjusted to the appropriate position, the user rotates the fixing bolts 214 clockwise, allowing them to pass through the slots 213 and thread into the selected holes on the sliding rods 212, then tightens them. In this way, the four sliding rods 212 are fixed at the new height position, thereby realizing the adjustment of the height of the support plate 3. Since the holes on the sliding rods 212 are spaced four centimeters apart, combined with the four-centimeter height of the base column 211, the height of the support plate 3 can be adjusted to three positions: four centimeters (lowest position of the sliding rod, only the height of the base column matters), eight centimeters (sliding rods slide up one position), and twelve centimeters (sliding rods slide up two positions).

[0044] In one embodiment of this utility model, such as Figures 1-3 As shown, the operation panel 62 includes a display screen 621, a microcontroller 622, and three buttons 623.

[0045] It is understandable that, in the actual use of this device, the operation panel 62 undertakes the key human-computer interaction function, and its workflow is as follows:

[0046] Power-on and Initial Display: When the device is powered on, the operation panel 62 begins to work. The display screen 621, which is fixedly mounted on one side of the top of the support rod 61, lights up and performs an initial display. Since weight monitoring and target weight setting have not been performed before training begins, the display screen 621 may display initial default values, such as the current monitored weight being displayed as "0" and the target weight being displayed as the default initial value.

[0047] Setting the target weight: Users need to set a target weight based on their training plan or rehabilitation program. At this time, the three buttons 623 on the display screen 621 come into play. These three buttons 623 are the "Increase" button, the "Decrease" button, and the "Confirm" button.

[0048] To increase the target weight value, the user presses the "Increase" button. Each press of the "Increase" button sends a signal to the microcontroller 622 located inside the display screen 621. Upon receiving the signal, the microcontroller 622 increases the current target weight value (assuming each increase is a preset fixed value, such as 1 kg), and then sends the updated target weight value to the display screen 621 for display.

[0049] Conversely, to reduce the target weight value, the user presses the "Reduce" button. The "Reduce" button sends a signal to the microcontroller 622. After receiving the signal, the microcontroller 622 reduces the current target weight value (assuming that the weight reduction is a preset fixed value, such as 1 kg), and then feeds back the updated target weight value to the display screen 621 for display.

[0050] Confirm Target Weight: After the user adjusts the target weight to the desired value using the "Increase" or "Decrease" button, they press the "Confirm" button. The "Confirm" button sends a confirmation signal to the microcontroller 622. Upon receiving this signal, the microcontroller 622 stores the target weight value displayed on the screen 621 at this time, which will serve as the benchmark value for weight comparison during subsequent training.

[0051] The training process is as follows: When the user stands on the support plate 3 to begin training, multiple pressure sensors 4 monitor the weight supported by the lower limbs in real time and transmit the monitored weight signals to the microcontroller 622. After processing these signals, the microcontroller 622 sends the current monitored weight value to the display screen 621. At this time, the display screen 621 will simultaneously display the current monitored weight and the previously set and confirmed target weight, allowing the user to easily understand the comparison between the training weight and the target weight and adjust the training intensity in a timely manner.

[0052] In one embodiment of this utility model, such as Figures 1-3 As shown, the microcontroller 622 has a built-in weight comparison algorithm. When the weight measured by the pressure sensor 4 exceeds the set target weight, it sends an alarm signal to the alarm 7.

[0053] It is understandable that the weight comparison algorithm built into the 622 microcontroller plays a crucial role during the normal operation of the device, and its specific workflow is as follows:

[0054] Data reception: When the user stands on the support plate 3 to begin training, the pressure sensors 4, which are evenly distributed on the top of the support plate 3, begin to monitor the weight supported by the lower limbs in real time. The pressure sensors 4 convert the monitored pressure signals into electrical signals and continuously transmit them to the microcontroller 622 in the operation panel 62.

[0055] Weight Comparison: After receiving the signal from the pressure sensor 4, the microcontroller 622 first processes the signal and converts it into actual weight data. At this time, the microcontroller 622 calls the built-in weight comparison algorithm to compare the processed actual weight data with the target weight previously set and confirmed via the button 623 on the operation panel 62.

[0056] Judgment and Alarm: During the continuous comparison process, once the microcontroller 622 determines that the actual weight measured by the pressure sensor 4 exceeds the set target weight, the microcontroller 622 will immediately execute the next operation. Since the microcontroller 622 is electrically connected to the alarm 7 located at the top of the operation panel 62, the microcontroller 622 will send an alarm signal to the alarm 7.

[0057] In one embodiment of this utility model, such as Figures 1-3 As shown, the alarm 7 includes a sound alarm 71 and a light alarm 72. When an alarm signal is received, it will simultaneously emit sound and flash light to sound an alarm.

[0058] It is understandable that during the operation of this device, alarm 7 plays an important role in ensuring the safety of users during training, and its specific working process is as follows:

[0059] Receiving alarm signals: When the user performs lower limb support training, if the weight measured by the pressure sensor 4 exceeds the set target weight, the microcontroller 622 in the operation panel 62 will make a judgment based on the built-in weight comparison algorithm and send an alarm signal to the alarm 7. The alarm 7, as the receiving end, is always ready to receive instructions from the microcontroller 622.

[0060] The audible alarm 71 is activated: Upon receiving the alarm signal, the internal circuitry of the alarm 7 responds quickly, and the audible alarm 71 begins operation. The sound-generating element of the audible alarm 71 vibrates mechanically under the drive of the electrical signal, thus emitting a loud sound. The volume and frequency of this sound are specially designed to be clearly audible to the user in a training environment; for example, it can emit a sharp buzzing sound, allowing the user to promptly detect abnormalities even in noisy training environments.

[0061] Light alarm 72 is activated: Almost simultaneously with the activation of the sound alarm 71, the light alarm 72 also begins to operate. The light-emitting element (LED) inside the light alarm 72 begins to flash rhythmically after receiving the electrical signal corresponding to the alarm signal.

[0062] Continuous alarm and feedback: The sound alarm 71 and light alarm 72 will continuously emit sound and flash light until the user adjusts the training weight so that the weight measured by the pressure sensor 4 is lower than the set target weight, at which point the microcontroller 622 will stop sending alarm signals. This synchronized sound and light alarm provides clear feedback to the user from both auditory and visual perspectives, ensuring that the user can take timely measures to avoid injury caused by excessive training weight, effectively protecting the user's safety during training.

[0063] In one embodiment of this utility model, such as Figures 1-3 As shown, the microcontroller 622 is electrically connected to multiple pressure sensors 4, a display screen 621, three buttons 623 and an alarm 7. It is used to process the signals transmitted from the pressure sensors 4, receive the operation commands of the buttons 623, control the display screen 621 to display the corresponding content, and send an alarm signal to the alarm 7 when the monitored weight exceeds the set value.

[0064] It is understandable that during the operation of this lower limb support training weight quantification alarm device, the 622 microcontroller, as the core control component, works in conjunction with multiple components. The specific workflow is as follows:

[0065] 1. Receive and process the signal from pressure sensor 4.

[0066] When a user stands on the support plate 3 for lower limb support training, multiple pressure sensors 4, evenly distributed on the top of the support plate 3, begin to monitor the weight of the user's lower limbs in real time. The pressure sensors 4 convert the sensed pressure into electrical signals, and transmit these signals to the microcontroller 622 through electrical connection lines.

[0067] After receiving these electrical signals, the microcontroller 622 performs a series of processing steps. First, the signal is amplified because the original signal output by the pressure sensor 4 is usually quite weak and needs to be amplified to a suitable amplitude for subsequent processing. Next, filtering is performed to remove any interference noise from the signal, ensuring its accuracy. Finally, the processed analog signal is converted into a digital signal so that the microcontroller 622 can perform numerical calculations and comparisons to obtain the actual weight value supported by the user's lower limbs.

[0068] 2. Receive operation instructions from button 623

[0069] The three buttons 623 on the operation panel 62, namely the "Increase" button, the "Decrease" button, and the "Confirm" button, are tools for the user to interact with the device and set the target weight. When the user presses these buttons, the buttons 623 generate corresponding electrical signals, which are transmitted to the microcontroller 622 through the electrical connection lines.

[0070] If the user presses the "Increase" button, the 622 microcontroller will receive the signal and increase the currently stored target weight value by a preset step (e.g., 1 kg).

[0071] If the "Decrease" button is pressed, the 622 microcontroller will reduce the target weight value by a preset step.

[0072] When the user presses the "Confirm" button, the 622 microcontroller will save the currently adjusted target weight value as a benchmark for subsequent weight comparisons.

[0073] 3. Control the display screen 621 to display the corresponding content.

[0074] After the microcontroller 622 processes the signal from the pressure sensor 4 to obtain the actual weight value and receives the operation command from the button 623 to set the target weight value, it will control the display screen 621 to display the corresponding content.

[0075] The microcontroller 622 sends the processed actual weight value to the display screen 621 through the electrical connection line, and the display screen 621 displays it so that the user can know the current training weight in real time.

[0076] At the same time, the microcontroller 622 will also send the saved target weight value to the display screen 621, so that the display screen 621 can display both the target weight and the actual weight at the same time, making it convenient for users to compare.

[0077] 4. Weight comparison and alarm signal transmission

[0078] The 622 microcontroller continuously compares the actual weight value with the target weight value while processing and saving the actual weight value. It calls the built-in weight comparison algorithm to compare the actual weight value with the target weight value.

[0079] Once the microcontroller 622 determines that the actual weight exceeds the set target weight, it will immediately send an alarm signal to the alarm 7 via the electrical connection line. Upon receiving the signal, the alarm 7 will emit an audible and flashing light warning to remind the user that the current training weight is too heavy and needs to be adjusted in time to ensure the safety of the training.

[0080] It should be noted that the control method of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.

[0081] Specifically, in actual implementation, assuming a tall rehabilitation patient needs to use this lower limb support training weight quantification alarm device for training, the specific usage process is as follows:

[0082] 1. Preparation: The patient places the device on a stable floor in the rehabilitation training room, where the base plate 1 provides stable support for the entire device. The patient decides to adjust the height of the support plate 3 according to their own height. They locate the lifting component 21 in the lifting device 2, finding four base columns 211 positioned on top of the base plate 1, each column 211 being four centimeters high. The patient rotates the four fixing bolts 214 on one side of the base column 211 counterclockwise, gradually disengaging them from the holes on the sliding rod 212, thus loosening the fixation on the sliding rod 212. Since there are two holes spaced four centimeters apart on one side wall of the sliding rod 212, the patient slides the four sliding rods 212 upwards along the base column 211, aligning the fixing bolts 214 with the corresponding twelve-centimeter-high holes on the sliding rods 212. Then, the patient rotates the fixing bolts 214 clockwise, allowing them to pass through the slot 213 and thread into the selected hole on the sliding rod 212, tightening the bolts. This successfully adjusts the height of the support plate 3 to twelve centimeters.

[0083] 2. Setting the Target Weight: The patient connects the device to the power supply, and the operation panel 62 starts working. The display screen 621, fixedly mounted on one side of the top of the support rod 61, lights up and initializes its display, showing the current monitored weight as "0" and the target weight as the default initial value. Based on the therapist's advice, the patient needs to set the target weight to 25 kg. By pressing the "Increase" button 623 on the display screen 621, each press sends a signal to the microcontroller 622 inside the display screen 621. The microcontroller 622 increases the current target weight value by 1 kg and sends the updated target weight value to the display screen 621. When the target weight reaches 25 kg, the patient presses the "Confirm" button 623. The microcontroller 622 receives the confirmation signal and stores the 25 kg target weight value displayed on the display screen 621.

[0084] 3. Training Process: The patient begins lower limb support training. Multiple pressure sensors 4, evenly distributed on the top of the support plate 3, monitor the weight of the patient's lower limbs in real time and convert the monitored pressure signals into electrical signals, which are transmitted to the microcontroller 622 via electrical connection lines. After receiving these electrical signals, the microcontroller 622 first amplifies and filters the signals, and then converts the analog signals into digital signals to obtain the actual weight value of the patient's lower limb support. The microcontroller 622 sends the actual weight value to the display screen 621, which simultaneously displays the current monitored weight and the target weight of 25 kg. During the training process, as the patient gradually increases the strength of their lower limb support, the actual weight continuously rises. When the actual weight exceeds 25 kg, the microcontroller 622 calls its built-in weight comparison algorithm to determine that the actual weight exceeds the set target weight, and immediately sends an alarm signal to the alarm 7 located on the top of the operation panel 62 via electrical connection lines.

[0085] 4. Alarm Response: Upon receiving an alarm signal, the internal circuitry of alarm 7 responds rapidly. The sound-generating element of the audible alarm 71 vibrates mechanically under electrical signal drive, emitting a sharp buzzing sound; almost simultaneously, the LED inside the light alarm 72 begins to flash rhythmically. Hearing the sound and seeing the light, the patient realizes the training weight is too heavy and adjusts the lower limb support to reduce the weight. When the weight measured by pressure sensor 4 is below 25 kg, the microcontroller 622 stops sending alarm signals to alarm 7, the audible alarm 71 stops sounding, the light alarm 72 stops flashing, and the patient continues training. Throughout the training process, the patient can adjust the target weight at any time according to their own condition using buttons 623 on the operation panel 62 to adapt to the rehabilitation training needs of different stages.

[0086] In summary, the lower limb support training weight quantification alarm device of this utility model, through the cooperation of a pressure sensor and a microcontroller, can accurately measure and display the lower limb support weight, which facilitates trainees to formulate scientific training plans, helps rehabilitation patients to train accurately and accelerate rehabilitation. Its lifting device is height-adjustable to adapt to people of different heights, and has strong versatility. Moreover, when the training weight exceeds the set value, the alarm will sound an audible and visual alarm to prevent users from being injured due to excessive weight and ensure safety.

[0087] In the description of this specification, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.
