Description

Technical Field

[0001] The invention relates to the technical field of pilot training equipment, and in particular to an anti-gravity muscle strength and neck muscle training assessment device. Background Art

[0002] Modern high-performance fighters can generate very high positive acceleration (+Gz) during maneuvering flight, and pilots must perform anti-load maneuvers to withstand the effects of high G-value continuous +Gz. Otherwise, pilots are prone to central vision loss or even loss of consciousness, which seriously threatens flight safety.

[0003] Therefore, pilots should be equipped with special equipment to carry out anti-G training and assessment, so as to help them have better anti-G flying ability. Good anti-G ability of pilots is the basic requirement for combat readiness and training, and is also the inevitable way to reduce flight accidents, improve flight skills and enhance combat effectiveness.

[0004] Patent No. CN2680305Y discloses a cervical muscle trainer, and Patent No. CN201997055U discloses a cervical muscle trainer, both of which can only train the pilot's neck anti-load muscle strength.

[0005] Patent No. CN209188029U discloses a special physical training device, which belongs to the field of air force training equipment. It can train the neck anti-load muscle strength or the leg anti-load muscle strength separately, but the two cannot be trained at the same time. In addition, its leg training load design adopts a guide rod type weight plate, which needs to be connected by a transmission belt. However, because the pilot's leg strength is far greater than the bearing range of the belt, the belt itself has tension and is prone to cracking and breaking after long-term use, so it is difficult to achieve the test evaluation effect. In addition, its leg training must be done by both legs at the same time, and it is not possible to separate the left and right legs for separate test training.

[0006] The existing anti-G training equipment still has weak software functions and is unable to collect, analyze, process and provide feedback based on the tester's physiological information and training data, which needs to be further improved. Summary of the invention

[0007] The purpose of the present invention is to provide an anti-gravity muscle strength and neck muscle training evaluation device, which is used for training and measuring and evaluating the anti-gravity muscle and neck muscle strength of pilots.

[0064] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0065] As Figure 1 shown, the present invention provides an anti-G force muscle strength and neck muscle exercise evaluation device, including a frame 1. A seat 2, a neck muscle training device 3, and a leg muscle training device 4 are provided on the frame 1. The leg muscle training device 3 is located directly in front of the seat 2. The seat 2 is arranged in a front-high and rear-low inclined manner and is adjustable in the front-rear direction. The neck muscle training device is fixed to the back of the seat through a suspension and is designed integrally with the seat.

[0066] The neck muscle training device of the present invention is integrally designed with the seat, and the whole can move synchronously with the seat to ensure the relative position of neck training, so that the neck and legs can be trained simultaneously or separately, providing more training options for the trainers to meet the actual needs of the trainers.

[0067] As Figure 2As shown in the figure, the neck muscle training device 3 is provided with a suspension 31, a headrest 32 and a first load adjustment device 33. The suspension 31 is fixed to the back side of the seat 2 and integrated with the seat 2. The first load adjustment device 33 is provided with a movable arm 331 and a resistance adjustment unit 332. The resistance adjustment unit 332 is installed on the suspension 31. A number of groups of pulleys 333 are provided on the suspension 31. The movable arm 331 is installed on the suspension 31, and the movable arm 331 is connected to the resistance adjustment unit 332 through a pull rope 334 installed on the pulley 333. The headrest 32 is installed at the lower end of the movable arm 331, and a first pressure sensor is provided inside the headrest 32;

[0068] When the neck muscle training device of the present invention is in training, by applying force to the headrest with the neck, the headrest drives the movable arm to rotate, and then the pull rope drives the resistance adjustment unit to provide a load. The first pressure sensor measures the pressure. The measurement range of the first pressure sensor is 0 to 500 N, and its measurement accuracy is 1 N. With high measurement accuracy, the present invention can increase the measurement range of the pressure by setting multiple first pressure sensors.

[0069] The leg muscle training device 4 is located at the front side of the seat 2, as Figure 3 shown. It is provided with a pedal 41 and a second load adjustment device 42. The second load adjustment device 42 is provided with a rotating shaft 421. A left rotating frame 422 and a right rotating frame 423 are provided on the rotating shaft 421. Corresponding left and right pedals 41 are respectively provided on the backs of the left and right rotating frames. A bearing rod 4201 is provided on the front sides of the left and right rotating frames. Different numbers of weight hanging pieces 42011 can be hung on the bearing rod 4201 according to needs to adjust the load on the pilot's legs. No less than four second pressure sensors are respectively provided on the rear sides of the left and right pedals 41.

[0070] The leg muscle training device of the present invention adopts a hanging piece design. A certain number of weight hanging pieces 42011 can be hung on the bearing rod 4201 of the rotating frame according to needs. As Figure 4 shown, the weight hanging piece 42011 is installed on the bearing rod 4201 through a through hole 42012 provided in the middle. The weight hanging piece 42011 has different specifications and weights for the pilot to reasonably select. The pilot rotates the rotating frame equipped with the weight hanging piece by directly stepping on the pedal to achieve leg muscle exercise, solving the problem that due to the very large leg muscle strength of the pilot, in the traditional guide rod type load, the belt drive is used, and the force on the belt cannot reach its bearing range, resulting in the inability to meet the training and test effects. In the above design, multiple second pressure sensors are provided, and the pressure measurement range can reach 0 - 3000 N, meeting the test intensity of the pilot's leg strength.

[0071] As Figure 5As shown, the resistance adjustment unit 332 is provided with two groups of guide rods 3321. The guide rods 3321 are fixed on the suspension 31. A number of groups of counterweight plates 3322 stacked in the height direction are strung on the guide rods 3321. Each group of counterweight plates 3322 is provided with a through hole 3323 on the side. A pull rod 3324 passing through the middle of the counterweight plates 3322 is arranged between the guide rods 3321. The upper end of the pull rod 3324 is fixedly connected to the pull rope 334, and the lower end of the pull rod 3324 is not fixed. The pull rod 3324 is provided with pin holes corresponding to the through holes 3323 of the counterweight plates one by one. The resistance adjustment unit further includes a pin 3325 that can be adjusted to insert into the through hole 3323 of the counterweight plate.

[0072] In the above structure, the number of counterweight plates to be pulled can be set according to training needs first. Insert the pin into the through hole 3323 of the counterweight plate 3322 to be pulled. At the same time, the pin will insert into the corresponding pin hole on the pull rod 3324, so that the lower end of the pull rod 3324 can be fixedly connected to the counterweight plate 3322 where the pin is inserted. When the trainer squeezes the headrest, it rotates through the flip arm 3311, drives the pull rope 334 to pull up the counterweight plate 3322 with the pin and the counterweight plates above it together with the pull rod, thereby exercising the neck muscles. The present invention adjusts the number of counterweight plates participating in the counterweight by inserting the pin into the through holes of different counterweight plates, so as to realize the adjustment of the resistance load, and the adjustment is convenient and reliable.

[0073] As Figure 6 As shown, the movable arm 331 includes a rotating frame 3312 in an "L" shape, and a flip arm 3311 hinged to the lower end of the rotating frame 3312 through a support shaft. The upper end of the suspension 31 is provided with a positioning disk 311. A hollow rotating shaft 312 is installed in the positioning disk 311 through a bearing. The end of the rotating frame 3312 is fixed to the hollow rotating shaft 312. A spring pull pin 313 is provided at the front end of the rotating frame 3312. The positioning disk 311 is provided with several groups of pin holes 314 evenly distributed in a circle, and the spring pull pin 313 can be snapped into the matching pin hole 314 for positioning. The pull rope 334 passes through the hollow rotating shaft 312 of the positioning disk and is then connected to the end of the flip arm 3311 through a pulley 333 installed on the rotating frame 3312.

[0074] In the above structure, the spring pull pin 313 on the positioning disk 311 can be pulled out. The rotating frame 3312 can rotate in a circle along the positioning disk 311 through the hollow rotating shaft 312, rotate to an appropriate angle to a position considered suitable by the trainer, and then be positioned by inserting the spring pull pin 313 into the pin hole of the positioning disk. The pin hole can be designed in one gear of 12 degrees. At the same time, the headrest can rotate back and forth along the rotating frame with the flip arm 3311, so that the trainer can exercise the muscles of multiple different positions of the neck, and the adjustment is simple and the operation is convenient.

[0075] As Figure 7As shown, the first load adjusting device 33 is further provided with a resistance moment adjusting unit 335. The resistance moment adjusting unit 335 is provided with a graduated adjusting rod 3351. One end of the adjusting rod 3351 is fixedly connected to the headrest 32, and the other end is installed and movably connected inside the tubular turning arm 3311. A knob 3352 for locking the adjusting rod is provided on the turning arm 3311.

[0076] In the above structure, the adjusting rod 3351 is graduated and can be adjusted steplessly. When the load is certain, by adjusting the length of the adjusting rod to change the resistance moment, the pilot can perform isometric long neck muscle training, thereby increasing the tension of the neck muscles without changing the length of the muscles, and the static muscle strength of the neck can be exercised.

[0077] As Figure 8 shown, the frame 1 is provided with a base 11. Above the front side of the base 11, a fixed bracket 12 is provided. Around the lower part of the base 11, adjustable feet 13 are provided.

[0078] The fixed bracket 12 includes a front column 121 and a rear column 122. Above the front column 121 and the rear column 122, a frame 123 is provided. Oppositely arranged reinforcing supports 124 are respectively provided on the rear column 122. A reinforcing beam 125 is provided between the reinforcing supports 124. The fixed bracket 12 is used for installing and fixing the leg muscle training device 4.

[0079] As Figure 9 shown, the seat 2 is provided with a support 21. The support 21 is fixed on the frame 1 with the front part higher and the rear part lower. An inclined linear slide rail 22 is provided on the support 21. A slide block 23 is provided at the lower part of the seat 2 and is installed on the slide rail 22. The slide block 23 is driven and connected to a motor 24 installed at the bottom of the frame through a lead screw 25.

[0080] The seat of the present invention is inclined, which is more conducive to the training personnel to exercise the leg strength. Moreover, by adjusting the front and rear positions of the seat, the height of the seat can also be adjusted at the same time. It is automatically adjusted by the lead screw motor, and the adjustment is convenient and fast.

[0081] On both sides of the seat 2, first armrests 26 are provided to assist the training personnel in exercising. During the exertion process, the training personnel can hold the handles to keep the body stable.

[0082] The seat of the present invention adopts an ergonomic design to ensure the comfort of the user's body feeling.

[0083] On the frame 123 on the front side of the seat 2, second armrests 1231 are provided to facilitate the training personnel to enter or leave the training position.

[0084] Except for the single - foot and double - foot switching device part, the rest of the left and right rotating frames are symmetrically designed. Taking the left rotating frame 422 as an example, asFigure 10 As shown, the left rotating frame 422 includes two groups of vertical beams 4202. One end of each vertical beam 4202 is fixed on the rotating shaft 421. A cross beam 4203 is provided between the lower sides of the vertical beams 4202. Diagonal beams 4204 are connected to the outer sides of the vertical beams 2402. Connecting seats 4205 for mounting the load-bearing rods 4201 are provided on the cross beam 4203 and the diagonal beams 4204. Two groups of load-bearing rods are arranged on each rotating frame, which can hang more counterweight hanging pieces, improving the load training range and better meeting the leg muscle exercise of pilots.

[0085] Combined with Figure 3 As shown, a single-foot / double-foot switching device 426 is provided between the left rotating frame 422 and the right rotating frame 423. As Figure 10 shown, the single-foot / double-foot switching device 426 is provided with upper and lower groups of female rods 4261 and male rods 4262 penetrating the vertical beams between the vertical beams 4202 of the left rotating frame 422. The corresponding right rotating frame is provided with male rods 4262 and female rods 4261 matching the left rotating frame. A handle 42621 is provided at the outer end of the male rod 4262, and a handle 42611 is provided at the outer end of the female rod 4261. A pipe hole is provided on the female rod 4261 for the male rod 4262 of the other rotating frame to be inserted into its interior for matching. The female rod 4261 and the male rod 4262 can be horizontally moved (in the direction indicated by the arrow in Figure 10 ) on the vertical beams 4202 to achieve connection and separation.

[0086] A clamping seat 42612 matching the handle 42611 is provided on the vertical beam 4202 to fix the position of the handle 42611 when the female rod and the male rod are connected.

[0087] In the present invention, by designing a single-foot / double-foot switching device, when the male and female rods of the left rotating frame 422 and the female and male rods of the right rotating frame are connected, the left and right rotating frames are integrally linked to achieve simultaneous exercise of both leg muscles. Similarly, when the male and female rods of the left and right rotating frames are separated, the left and right leg muscles can be exercised separately. The functional design of its linkage or separate movement enriches the fun of training and meets the actual needs of training personnel.

[0088] As Figure 11 shown, a buffer cushion block 1211 is provided on the front vertical column 121 of the fixed bracket 12, and a distance sensor is provided inside the buffer cushion block 1211. The buffer cushion block 1211 is arranged at the landing point of the diagonal beam 4204 in the original state of the rotating frame, which can prevent the diagonal beam 4204 from directly colliding with the front vertical column 121 during the return of the pedal kick-out, causing hard contact. A distance sensor is installed inside it, which can measure the torque stroke of the rotating frame.

[0089] The second load adjustment device 42 is provided with a quick locking mechanism 427 to realize the switching between the isometric training mode and the isotonic training mode.

[0090] The quick locking mechanism 427 includes a rotatable lever 4271, and a right-angled elbow 4272 is provided at the end of the lever 4271. The lever 4271 penetrates through the front and rear columns and is located above the buffer cushion block 1211. A notch 4206 corresponding to the right-angled elbow 4272 is provided on the inclined beam 4204. The right-angled elbow 4272 can be engaged into the notch 4206 by rotating the lever 4271.

[0091] For the above-mentioned quick locking mechanism, when the lever is rotated to make the right-angled elbow 4272 engaged into the notch 4206 of the inclined beam, the rotating frame is locked. At this time, the training is in the "isometric training mode". During the process of forcefully pedaling, there is no displacement, but the magnitude of the pedaling force changes. A pressure sensor is arranged under the pedal, which can feedback the magnitude of the applied force. The present invention can perform muscle strength training independently or follow the pressure guiding curve of the system for training. On the contrary, when the rotating frame is not locked, it is movable, and at this time, it is the common "isotonic training mode".

[0092] As Figure 12 shown, the rotating shaft 421 is composed of two half shafts 4211 on the left and right, and the outer ends of the half shafts are fixed on the hinge seats 4212, and the hinge seats 4212 are installed on the fixed shaft 1232 of the frame 123 and are hinged.

[0093] The leg muscle training device 4 is further provided with a pedal angle adjusting device 43. The pedal angle adjusting device 43 is provided with a connecting block 431. A lead screw 432 is provided in the middle of the connecting block 431. The two ends of the connecting block 431 are respectively connected to the half shafts 4211. A sliding seat 433 is provided at the bottom of the connecting block 431. The sliding seat 433 is installed on the slide rail 434 and can slide. The slide rail 434 is installed on the frame 123 through a support plate 435. A rotating handle 436 is provided at the outer end of the lead screw 432.

[0094] By rotating the rotating handle 436 of the above-mentioned pedal angle adjusting device, the lead screw 432 drives the sliding seat 433 to slide on the slide rail 434, thereby driving the connecting block 431 to move. The connecting block drives the left and right half shafts to rotate a certain angle around the fixed shaft 1232, so as to realize the change of the pedal angle. The design of the present invention can make the pedal change by about 15 degrees to ensure that the training personnel are in a better leg training position.

[0095] As Figure 13 shown, an electrical box 14 is provided on the frame 1. The electrical box can place a power supply, an amplifier, a control board, etc. A placement box 15 is provided on the side of the resistance adjusting unit 332. The placement box 15 is fixed on the suspension 31 through a support plate 16. The placement box is used to store a breathing mask, electrocardiogram electrodes, etc.

[0096] The exercise evaluation device of the present invention further includes a test system, which includes a connected data acquisition module, a data analysis module, a data storage module, a data display module, and a control module. The data acquisition module is connected to a first pressure sensor, a second pressure sensor, a distance sensor, and a physiological signal acquisition device. The data acquisition module is used to collect the physiological parameters of the test personnel. The data analysis module is used to analyze the collected data and feedback it to the control module. The data storage module is used to store the collected and analyzed feedback data. The data display module is used to set, record, or read the information of the test personnel and training information.

[0097] As Figure 1 shown, the data display module uses a color touch screen 51, which is installed on the frame 123 directly in front of the seat 2. It is convenient for the training personnel to observe their training status in real time, and they can make timely adjustments according to needs to ensure the safety and effectiveness of the training.

[0098] The physiological signal acquisition device includes an electrocardiogram electrode and a respiratory pressure sensor, which can collect physiological parameters such as the heart rate, electrocardiogram, and respiration of the training personnel, and conduct scientific exercise analysis.

[0099] The control module is controlled by a computer, and the control is more convenient and reliable.

[0100] The test system of the present invention can measure and evaluate the exercise of the neck muscle strength and anti-G muscles of pilots, can set and provide training according to the needs of the test personnel, and provides the effectiveness, safety, and scientific nature of the training through visual biofeedback strength training with traced curves.

[0101] The test system of the present invention assists in exercise, and the specific work is as follows:

[0102] First, set the training parameters through the data display module according to the needs of the test personnel. The test system generates a training guidance curve according to the set relevant parameters. At the same time, the curve of the training result of the test personnel is traced through the data acquisition module, the data analysis module, and the control module and displayed in the data display module to help the test personnel exercise according to the guidance curve to achieve visual biofeedback strength training;

[0103] Second, the test system can collect the physiological parameters of the test personnel while collecting the motion parameters and conduct scientific analysis and feedback to the test personnel;

[0104] Third, the test system can generate a strength training curve and a cycle training plan according to the evaluation results and settings.

[0105] As Figure 14 shown, visual biofeedback strength training is a human-machine interaction training process. When performing this function training, the system will generate, according to the set relevant parameters, such as Figure 13The guiding curve in it. The walking track of the dots in the figure is the information feedback of the trainer. When the trainer makes the dots move along the curve with an appropriate output (force when isometric, amplitude when isotonic), visual biofeedback training is achieved. The set curve parameters include: number of times, number of sets, movement time, rest time between sets, amplitude, force, etc. Entering the specific values of the above items in the setting interface can generate the curve, and the movement speed, range of motion, number of times, number of sets, and rest time can be restricted according to the curve, thus ensuring the safe training of the testers.

[0106] The present invention is used for the exercise, measurement and evaluation of the anti-G muscles and neck muscles of pilots. It can provide an equipment platform for the anti-G exercise and neck muscle strength training of pilots by adjusting different mechanical loads, and can monitor the physical condition of pilots during the exercise, evaluate the muscle strength ability and exercise effect of pilots, and provide a reference for exercise load.

[0107] The present invention has a guiding curve and evaluation function for standard anti-G breathing actions, can manage users and replay historical data, and can also perform visual biofeedback strength training. It can set and provide training according to the needs of testers to ensure the effectiveness, safety and scientific nature of the training.

[0108] Testers of the present invention can exercise the neck muscles and leg muscles synchronously or separately, and there are respectively isometric and isotonic movement modes for the neck and leg strength tests and training.

[0109] The left and right pedals of the present invention can be linked or separated, and are used for the synchronous or separate exercise and test of the left and right leg muscles to meet the actual needs of the trainers.

[0110] The present invention is scientifically designed and user-friendly, and can provide a variety of rich training modes for pilots to meet the training needs of different trainers.
