Description

Technical Field

[0001] The present application relates to the technical field of medical equipment and sports training assistance, and in particular to a weight quantification alarm device for lower limb support training. Background Art

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

[0003] In the field of rehabilitation, the body functions of rehabilitation patients are in the recovery stage, and the training intensity needs to be strictly controlled to avoid secondary damage to the body caused by overtraining. However, existing rehabilitation training equipment often cannot accurately measure the weight of lower limb support. 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 it is difficult to ensure that every patient can get accurate and appropriate training volume. For example, for patients in the recovery period after a fracture, the initial lower limb support training weight needs to be strictly controlled at a low level. If the training weight is too large, it may affect the healing of the fracture site; and for patients with muscle atrophy, the training weight needs to be gradually increased according to the muscle recovery. The lack of quantitative means makes it difficult for training to achieve ideal results.

[0004] In addition, existing training equipment also has limitations in height adjustment. Most equipment has a fixed height and cannot meet the needs of users of different heights, which limits the versatility of the equipment and makes the training experience poor. Moreover, during training, once the training weight exceeds the safe range, there is a lack of an effective alarm mechanism, which makes it difficult for users to detect it in time, further increasing the risk of injury.

[0005] In summary, developing a training device that can accurately measure the weight supported by the lower limbs, achieve height adjustment, have an alarm function and is easy to operate is of great significance for improving the effect of lower limb rehabilitation training and the quality of sports training. Summary of the invention

[0006] The present application aims to solve one of the technical problems in the related art at least to some extent.

[0007] To this end, the first purpose of this application is to provide a lower limb support training weight quantification alarm device, which can accurately measure and display the lower limb support weight through the cooperation of pressure sensors and single-chip microcomputers, so that trainees can formulate scientific and reasonable training plans according to their own conditions and improve training effects. For rehabilitation patients, it helps doctors and rehabilitation therapists to accurately adjust the training intensity according to the patient's recovery stage and accelerate the rehabilitation process.

[0008] The second purpose of the present application is to provide a weight quantification alarm device for lower limb support training. The design of the lifting device makes the height of the device adjustable to adapt to users of different heights, thereby improving the versatility of the device. Whether it is a tall adult or a short child rehabilitation patient, they can get a comfortable training experience by adjusting the height of the device.

[0009] The third purpose of this application is to provide a lower limb support training weight quantification alarm device. When the training weight exceeds the set value, the alarm will promptly send out 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.

[0010] To achieve the above-mentioned purpose, the first aspect of the present application proposes a lower limb support training weight quantification alarm device, including a base plate, a lifting device, a support plate, multiple pressure sensors, an operating device and an alarm, wherein the lifting device includes a lifting assembly, wherein the lifting assembly is slidably arranged 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 weight supported by the lower limbs; the operating device includes a support rod and an operating panel, wherein the support rod is fixedly arranged on one side of the top of the support plate; the operating panel is arranged on the top of the support rod, and is electrically connected to multiple pressure sensors, respectively, for receiving and processing signals from the pressure sensors; the alarm is arranged on the top of the operating panel, and the alarm is electrically connected to the operating panel, and an alarm signal is issued when the monitored weight exceeds the set value.

[0011] A lower limb support training weight quantification alarm device in an embodiment of the present application can accurately measure and display the lower limb support weight through the cooperation of a pressure sensor and a single-chip microcomputer, which is convenient for trainers to formulate scientific training plans, help rehabilitation patients to train accurately and accelerate rehabilitation. Its lifting device can adjust the height to adapt to people of different heights and has strong versatility. Moreover, when the training weight exceeds the set value, the alarm will emit an audible and visual alarm to prevent users from being injured due to excessive weight and ensure safety.

[0012] In addition, the lower limb support training weight quantification alarm device proposed in the present application may also have the following additional technical features:

[0013] In one embodiment of the present application, the lifting assembly includes four base columns, four sliding rods, four empty slots and four fixing bolts, wherein the four base columns are respectively arranged on the top of the base plate with a height of four centimeters; the four sliding rods are respectively slidably arranged on the four base columns, and two holes are arranged on one side wall of the four sliding rods at intervals of four centimeters; the four empty slots are respectively arranged on one side of the four base columns; the four fixing bolts respectively pass through the four empty slots and are threadedly connected with the corresponding holes, and the height of the support plate can be adjusted to three positions of four centimeters, eight centimeters and twelve centimeters through adjustment.

[0014] In one embodiment of the present application, the operation panel includes a display screen, a single-chip microcomputer, and three buttons, wherein the display screen is fixedly arranged on one side of the top of the support rod, for displaying the current monitored weight and the set target weight; the single-chip microcomputer is arranged inside the display screen; the three buttons are respectively arranged on the display screen, namely, an "increase" button, a "decrease" button and a "confirm" button, for setting the target weight.

[0015] In one embodiment of the present application, the single chip microcomputer has a built-in weight comparison algorithm, and when the weight measured by the pressure sensor exceeds the set target weight, an alarm signal is sent to the alarm.

[0016] In one embodiment of the present application, the alarm includes a sound alarm and a light alarm. When an alarm signal is received, a sound and a flashing light are emitted simultaneously to give an alarm.

[0017] In one embodiment of the present application, the single chip microcomputer is electrically connected to the plurality of pressure sensors, the display screen, the three buttons and the alarm, respectively, and is used to process the signals transmitted from the pressure sensors, receive the operation instructions of the buttons, control the display screen to display the corresponding content, and send an alarm signal to the alarm when the monitored weight exceeds the set value.

[0018] The pressure sensor uses a high-precision strain gauge pressure sensor, the FSG-101 pressure sensor that is matched with the HX711. This type of pressure sensor has high measurement accuracy and can accurately measure the slight weight changes supported by the lower limbs, meeting the high-precision requirements of this device for weight monitoring. The measurement range is 0-200kg, which can adapt to weight measurement under different training intensities.

[0019] The single-chip microcomputer uses STC89C52 single-chip microcomputer. It has rich on-chip resources and can meet the data processing and control needs of this device.

[0021] The sound alarm uses an active buzzer, model FMQ-2720S. The working voltage range of the buzzer is 3-5V, which matches the power supply voltage of this device. The sound it emits is loud and clear, which can effectively attract the user's attention in the training environment and promptly remind the user that the training weight exceeds the standard.

[0022] The light alarm uses a red LED light, such as a 5mm ultra-bright red LED. It has high brightness and fast response speed. When receiving an alarm signal, it can flash quickly to remind the user with a striking visual effect, and cooperate with the sound alarm to achieve a sound and light synchronous alarm.

[0025] (2) The design of the lifting device makes the height of the device adjustable to accommodate users of different heights, thus improving 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.

[0026] (3) When the training weight exceeds the set value, the alarm will promptly send out 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.

[0027] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0034] A lower limb support training weight quantification alarm device according to an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0035] like Figure 1-Figure 3 As shown, a lower limb support training weight quantification alarm device according to an embodiment of the present application may include a base plate 1, a lifting device 2, a supporting plate 3, multiple pressure sensors 4, an operating device 6 and an alarm 7.

[0036] It is understandable that, in specific implementation, the lower limb support training weight quantification alarm device works according to the following process:

[0037] Preparation: Place the device on a stable ground, and the bottom plate 1 plays a role in stably supporting the entire device. The user can adjust the height of the support plate 3 through the lifting device 2 according to their own needs. The lifting component 21 in the lifting device 2 is slidably arranged on the top of the bottom plate 1. By operating the lifting component 21, the height of the support plate 3 can be changed to adapt to the height of different users.

[0038] Weight monitoring and data processing: At this time, the multiple pressure sensors 4 evenly distributed on the top of the support plate 3 start working, and they monitor the weight supported by the user's lower limbs in real time. The pressure sensor 4 converts the monitored weight signal into an electrical signal and transmits it to the operating device 6. The operating panel 62 in the operating device 6 is set on the top of the support rod 61 and is electrically connected to the multiple pressure sensors 4. It is responsible for receiving the signals from the pressure sensors 4 and processing them.

[0039] Alarm function triggering: Before use, the user will set a weight setting value on the operation panel 62 according to his own training plan or rehabilitation program. The operation panel 62 continuously processes the signal from the pressure sensor 4 and compares it with the set value. Once the monitored weight exceeds the set value, the operation panel 62 will send a signal to the alarm 7 set on the top of it. Since the alarm 7 is electrically connected to the operation panel 62, after receiving the signal, the alarm 7 will send an alarm signal to remind the user that the current training weight is too large and needs to be adjusted.

[0040] In one embodiment of the present application, Figure 1-Figure 3 As shown, the lifting assembly 21 includes four bottom columns 211 , four sliding rods 212 , four empty slots 213 and four fixing bolts 214 .

[0041] It is understandable that when the device is actually used, when the height of the support plate 3 needs to be adjusted to suit the height or training needs of different users, the lifting assembly 21 is operated, and the specific working process is as follows:

[0042] Preparation for adjustment: First, the user needs to make sure whether the current height of the support plate 3 meets their needs. At this time, it can be seen that four bottom columns 211 are respectively arranged on the top of the bottom plate 1. They are the basic supporting components of the entire lifting structure, and the height of each bottom column 211 is fixed to four centimeters.

[0043] Loosen the fixing bolts: If the height needs to be adjusted, the user finds the fixing bolts 214 located on one side of the bottom column 211. Because the four fixing bolts 214 pass through the four empty slots 213 and are threadedly connected to 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 and loosen the fixing effect on the sliding rod 212. The four empty slots 213 are respectively set on one side of the four bottom columns 211, and their function is to provide a movable space for the fixing bolts 214 so that the bolts can be connected to the holes at different positions on the sliding rod 212.

[0044] Adjusting the height of the sliding rod: After the fixing bolts 214 are loosened, the four sliding rods 212 can slide freely on the four bottom pillars 211. Since two holes are arranged on one side wall of the sliding rod 212 at an interval of four centimeters, the user can select the appropriate hole position according to the required height. For example, if the supporting plate 3 is to be raised from four centimeters to eight centimeters, the sliding rod 212 is slid upward along the bottom pillar 211 so that the fixing bolts 214 can be aligned with the hole on the sliding rod 212 corresponding to the eight centimeters height.

[0045] Fixing the sliding rod: When the sliding rod 212 is adjusted to a suitable position, the user rotates the fixing bolt 214 clockwise to pass through the empty slot 213 and threadedly connect with the selected hole on the sliding rod 212 and tighten it. In this way, the four sliding rods 212 are fixed at a new height position, thereby achieving the adjustment of the height of the supporting plate 3. Since the interval between the holes on the sliding rod 212 is four centimeters, combined with the four-centimeter height of the bottom column 211, the height of the supporting plate 3 can be adjusted to three positions: four centimeters (the lowest position of the sliding rod, only the height of the bottom column is effective), eight centimeters (the sliding rod slides up one gear) and twelve centimeters (the sliding rod slides up two gears).

[0046] In one embodiment of the present application, Figure 1-Figure 3 As shown, the operation panel 62 includes a display screen 621 , a single chip computer 622 , and three buttons 623 .

[0047] It can be understood that in the actual use of the device, the operation panel 62 undertakes the key human-computer interaction function, and its working process is as follows:

[0048] Power on and initial display: When the device is powered on, the operation panel 62 starts to work. The display screen 621 fixed to one side of the top of the support rod 61 lights up, and the display screen 621 will be initialized. Since weight monitoring and target weight setting have not been performed before training begins, the display screen 621 may display the initial default value, such as the current monitoring weight is displayed as "0", and the target weight is also displayed as the default initial value.

[0049] Setting target weight: The user needs to set a target weight according to his / her own training plan or rehabilitation program. At this time, three buttons 623 located on the display screen 621 come into play, and the three buttons 623 are respectively an "increase" button, a "decrease" button and a "confirm" button.

[0050] To increase the target weight value, the user presses the "Increase" button. Each time the "Increase" button is pressed, a signal is transmitted to the single-chip microcomputer 622 disposed inside the display screen 621. After receiving the signal, the single-chip microcomputer 622 increases the current target weight value (assuming that the weight value increased each time is a preset fixed value, such as 1 kg), and then sends the updated target weight value to the display screen 621 for display.

[0051] On the contrary, if the target weight value is to be reduced, the user presses the "reduce" button. The "reduce" button transmits a signal to the single-chip microcomputer 622. After receiving the signal, the single-chip microcomputer 622 reduces the current target weight value (suppose that the weight value reduced each time is a preset fixed value, such as 1 kg), and then feeds the updated target weight value back to the display screen 621 for display.

[0052] Confirm the target weight: After the user adjusts the target weight to the desired value through the "increase" button or the "decrease" button, the user presses the "confirm" button. The "confirm" button sends a confirmation signal to the single-chip microcomputer 622. After receiving the signal, the single-chip microcomputer 622 stores the target weight value displayed on the display screen 621 at this time as a reference value for weight comparison in subsequent training processes.

[0053] Display during training: When the user stands on the support plate 3 and starts training, the multiple pressure sensors 4 monitor the weight supported by the lower limbs in real time and transmit the monitored weight signals to the single chip microcomputer 622. After processing these signals, the single chip microcomputer 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, so that the user can understand the comparison between the training weight and the target weight at any time, so as to adjust the training intensity in time.

[0054] In one embodiment of the present application, Figure 1-Figure 3 As shown, the single chip microcomputer 622 has a built-in weight comparison algorithm, and when the weight measured by the pressure sensor 4 exceeds the set target weight, an alarm signal is sent to the alarm 7.

[0055] It is understandable that during the normal operation of the device, the weight comparison algorithm built into the microcontroller 622 plays a key role, and its specific working process is as follows:

[0056] Data reception: When the user stands on the support board 3 and starts training, the pressure sensors 4 evenly distributed on the top of the support board 3 start 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 single chip microcomputer 622 in the operation panel 62.

[0057] Weight comparison: After receiving the signal from the pressure sensor 4, the single-chip microcomputer 622 first processes the signal and converts it into actual weight data. At this time, the single-chip microcomputer 622 will call the built-in weight comparison algorithm to compare the processed actual weight data with the target weight previously set and confirmed by the button 623 on the operation panel 62.

[0058] Judgment and alarm: During the continuous comparison process, once the single-chip microcomputer 622 determines that the actual weight measured by the pressure sensor 4 exceeds the set target weight, the single-chip microcomputer 622 will immediately execute the next operation. Since the single-chip microcomputer 622 is electrically connected to the alarm 7 set on the top of the operation panel 62, the single-chip microcomputer 622 will send an alarm signal to the alarm 7 at this time.

[0059] In one embodiment of the present application, Figure 1-Figure 3 As shown, the alarm 7 includes a sound alarm 71 and a light alarm 72. When an alarm signal is received, it emits a sound and flashes a light to give an alarm.

[0060] It can be understood that during the operation of the device, the alarm 7 plays an important role in ensuring the safety of the user's training, and its working process is as follows:

[0061] 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 single-chip microcomputer 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 a receiving end, is always ready to receive instructions from the single-chip microcomputer 622.

[0062] The sound alarm 71 starts: After the alarm 7 receives the alarm signal, the internal circuit responds quickly, and the sound alarm 71 starts working first. The sound-generating element of the sound alarm 71 generates mechanical vibrations driven by the electrical signal, and then emits a loud sound. The volume and frequency of this sound are specially designed so that it can be clearly heard by the user in the training environment, such as a sharp buzzing sound, so that the user can detect abnormalities in a noisy training environment in a timely manner.

[0063] The light alarm 72 starts: Almost at the same time as the sound alarm 71 starts, the light alarm 72 also starts to work. After receiving the electrical signal corresponding to the alarm signal, the light emitting element (LED light) inside the light alarm 72 starts to flash regularly.

[0064] Continuous alarm and feedback: The sound alarm 71 and the light alarm 72 will continue to 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, and the single-chip computer 622 stops sending alarm signals. This method of synchronous sound and light alarm provides clear feedback to the user from both auditory and visual dimensions, ensuring that the user can take timely measures to avoid physical damage caused by excessive training weight, and effectively ensuring the safety of the user during training.

[0065] In one embodiment of the present application, Figure 1-Figure 3 As shown, the single chip computer 622 is electrically connected to multiple pressure sensors 4, a display screen 621, three buttons 623 and an alarm 7, respectively, and is used to process the signal from the pressure sensor 4, receive the operation instructions of the button 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.

[0066] It can be understood that during the operation of the lower limb support training weight quantification alarm device, the single chip microcomputer 622, as a core control component, works in coordination with multiple components. The specific working process is as follows:

[0067] 1. Receive and process the signal from pressure sensor 4

[0068] When the user stands on the support board 3 to perform lower limb support training, multiple pressure sensors 4 evenly distributed on the top of the support board 3 begin to monitor the weight supported by the user's lower limbs in real time. The pressure sensors 4 convert the pressure they feel into electrical signals and transmit these signals to the single chip computer 622 through electrical connection lines.

[0069] After receiving these electrical signals, the single-chip microcomputer 622 performs a series of processing on them. First, the signal is amplified, because the original signal output by the pressure sensor 4 is usually weak and needs to be amplified to a suitable amplitude for subsequent processing. Then, a filtering operation is performed to remove possible interference noise in the signal to ensure the accuracy of the signal. Finally, the processed analog signal is converted into a digital signal so that the single-chip microcomputer 622 can perform operations such as numerical calculation and comparison, thereby obtaining the actual weight value supported by the current user's lower limbs.

[0070] 2. Receive the operation instruction of button 623

[0071] 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 to set the target weight. When the user presses these buttons, the buttons 623 will generate corresponding electrical signals and transmit them to the single-chip computer 622 through the electrical connection line.

[0072] If the user presses the "increase" button, the single chip microcomputer 622 will increase the currently stored target weight value by a preset step size (eg, 1 kg) after receiving the signal.

[0073] If the "decrease" button is pressed, the microcontroller 622 decreases the target weight value by a preset step size.

[0074] When the user presses the "Confirm" button, the single chip microcomputer 622 will save the currently adjusted target weight value as a reference for subsequent weight comparisons.

[0075] 3. Control the display screen 621 to display the corresponding content

[0076] After processing the signal from the pressure sensor 4 to obtain the actual weight value and receiving the operation instruction from the button 623 to set the target weight value, the single chip microcomputer 622 will control the display screen 621 to display the corresponding content.

[0077] The single chip microcomputer 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 understand the current training weight in real time.

[0078] At the same time, the single chip microcomputer 622 will also send the saved target weight value to the display screen 621, so that the display screen 621 can display the target weight and the actual weight at the same time, which is convenient for the user to compare.

[0079] 4. Weight comparison and alarm signal sending

[0080] The microcontroller 622 continuously performs weight comparisons while processing the actual weight value and saving the target weight value. It calls the built-in weight comparison algorithm to compare the actual weight value with the target weight value.

[0081] Once the single chip computer 622 determines that the actual weight exceeds the set target weight, it will immediately send an alarm signal to the alarm 7 through the electrical connection line. After receiving the signal, the alarm 7 will emit an alarm prompt such as a sound and a flashing light to remind the user that the current training weight is too large and needs to be adjusted in time to ensure the safety of training.

[0082] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field, and the present application is mainly used to protect mechanical structures, so the present application will no longer explain the control method and circuit connection in detail.

[0083] Specifically, in the actual implementation process, assuming that a tall rehabilitation patient needs to use the lower limb support training weight quantification alarm device for training, the specific use process is as follows:

[0084] 1. Preparation: The patient places the device on the stable ground in the rehabilitation training room, and the bottom plate 1 plays a role in stably supporting the entire device. The patient decides to adjust the height of the support plate 3 according to his own height. He finds the lifting assembly 21 in the lifting device 2 and finds that the four bottom columns 211 are respectively set on the top of the bottom plate 1, and the height of each bottom column 211 is four centimeters. The patient rotates the four fixing bolts 214 on one side of the bottom column 211 counterclockwise, so that they gradually disengage from the holes on the sliding rod 212, and loosen the fixation of the sliding rod 212. Since two holes are set on one side wall of the sliding rod 212 at an interval of four centimeters, the patient slides the four sliding rods 212 upward along the bottom column 211, so that the fixing bolts 214 can be aligned with the holes on the sliding rod 212 corresponding to the height of twelve centimeters, and then rotates the fixing bolts 214 clockwise to make it pass through the empty slot 213 and threadedly connected with the selected hole on the sliding rod 212 and tightened, successfully adjusting the height of the support plate 3 to twelve centimeters.

[0085] 2. Set the target weight: The patient turns on the power of the device, the operation panel 62 starts working, the display screen 621 fixed on the top side of the support rod 61 lights up and initializes the display, the current monitored weight is displayed as "0", and the target weight is also displayed as the default initial value. According to the rehabilitation therapist's advice, the patient needs to set the target weight to 25 kg. He presses the "increase" button 623 on the display screen 621. Each time he presses it, a signal is transmitted to the single-chip microcomputer 622 set inside the display screen 621. The single-chip microcomputer 622 increases the current target weight value by 1 kg and sends the updated target weight value to the display screen 621 for display. When the target weight value reaches 25 kg, the patient presses the "confirm" button 623, and the single-chip microcomputer 622 receives the confirmation signal and stores the 25 kg target weight value displayed on the display screen 621 at this time.

[0086] 3. Training process: The patient starts lower limb support training. The multiple pressure sensors 4 evenly distributed on the top of the support plate 3 monitor the weight of the patient's lower limb support in real time, and convert the monitored pressure signal into an electrical signal, which is transmitted to the single-chip microcomputer 622 through the electrical connection line. After receiving these electrical signals, the single-chip microcomputer 622 first amplifies and filters the signals, and then converts the analog signals into digital signals to obtain the actual weight value of the current patient's lower limb support. The single-chip microcomputer 622 sends the actual weight value to the display screen 621, and the display screen 621 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 the lower limb support, the actual weight continues to rise. When the actual weight exceeds 25 kg, the single-chip microcomputer 622 calls the built-in weight comparison algorithm, determines that the actual weight exceeds the set target weight, and immediately sends an alarm signal to the alarm 7 set on the top of the operation panel 62 through the electrical connection line.

[0087] 4. Alarm response: After the alarm 7 receives the alarm signal, the internal circuit responds quickly. The sound element of the sound alarm 71 generates mechanical vibrations driven by the electrical signal and emits a sharp buzzing sound; almost at the same time, the LED light inside the light alarm 72 begins to flash regularly. After hearing the sound and seeing the light, the patient realizes that the training weight is too heavy, so he adjusts the support strength of the lower limbs to reduce the weight. When the weight measured by the pressure sensor 4 is less than 25 kilograms, the single-chip computer 622 stops sending alarm signals to the alarm 7, the sound alarm 71 stops sounding, the light alarm 72 stops flashing, and the patient continues training. During the entire training process, the patient can adjust the target weight at any time according to his own situation through the button 623 on the operation panel 62 to adapt to the rehabilitation training needs at different stages.

[0088] In summary, a lower limb support training weight quantification alarm device in an embodiment of the present application can accurately measure and display the lower limb support weight through the cooperation of a pressure sensor and a single-chip microcomputer, which is convenient for trainers to formulate scientific training plans, help rehabilitation patients to train accurately, and accelerate rehabilitation. Its lifting device can adjust the height to adapt to people of different heights and has strong versatility. Moreover, when the training weight exceeds the set value, the alarm will emit an audible and visual alarm to prevent users from being injured due to excessive weight and ensure safety.
