Description

Technical Field

[0001] The present invention relates to the technical field of medical fitness machinery, and in particular to fitness medical rehabilitation equipment using a resistance power box and a resistance power box. Background Art

[0002] In the field of fitness and medical rehabilitation, the effectiveness, safety and adaptability of equipment have always been the focus of attention. With the improvement of people's health awareness and the growing demand for rehabilitation, higher requirements are placed on the performance of fitness and medical rehabilitation equipment.

[0003] Traditional fitness equipment has relatively simple functions and can only provide fixed-mode exercise training, and cannot be adjusted according to the individual differences of users. For medical rehabilitation scenarios, this "one-size-fits-all" design seriously restricts the rehabilitation effect. The physical conditions, rehabilitation stages and athletic abilities of different patients vary greatly. Equipment of the same mode may cause harm to weak patients due to excessive power, and may not meet the training needs of patients with better recovery due to too little power, resulting in a slow rehabilitation process; in terms of power transmission, the transmission structure of traditional equipment is simple and the transmission methods are limited. For example, the common single belt drive or gear drive cannot meet the diverse power output requirements of complex rehabilitation training. The single transmission method is either insufficient in stability, generating large noise and vibration, affecting the user's psychological state; or it is limited in the speed ratio adjustment range, making it difficult to achieve fine adjustment of the training intensity according to the rehabilitation progress. Summary of the invention

[0010] Furthermore, a second pulley is fixedly provided at one end of the output shaft of the driving motor, a first pulley is fixedly provided on the surface of the power transmission rod, and the first pulley and the second pulley are connected via a transmission belt.

[0011] Furthermore, a driving gear is fixedly provided on one end of the output shaft of the driving motor, a driven gear is fixedly provided on the surface of the power transmission rod, and the driving gear meshes with the driven gear for transmission.

It is connected to the fixed bracket through a limit sleeve and a connecting sleeve rod. When adjusting the height, the limit elastic block is pressed to make the limit column withdraw from the limit hole of the connecting sleeve rod. At this time, the position of the connecting sleeve rod in the limit sleeve can be easily adjusted up and down. When the appropriate height is adjusted, the limit elastic block is released. Under the action of the spring, the limit column is reinserted into the corresponding limit hole to achieve precise positioning. This design is not only simple to operate, but also can meet the use needs of people of different heights, greatly improving the applicability of the equipment; 2. The angle adjustment structure of the adjustable backrest also fully considers the use needs of people of different heights.

The rotating connection seats on the front and rear sides of the fixed bracket support the rotating bracket so that it can rotate flexibly. When the power transmission rod inside the resistance power box rotates, it drives the rotating parts at both ends to rotate, and then drives the rotating bracket to swing left and right through the connecting movable arm. The user holds the fitness handle with both hands, and can carry out targeted rehabilitation training in this process; 3. The resistance power box proposed in the present invention provides three different transmission modes: belt drive, gear drive and multi-chain multi-stage drive. Different usage scenarios and rehabilitation training needs have different requirements for transmission characteristics. In some environments with high requirements for transmission stability and strict noise restrictions, belt drive is a good choice. Belt drive has the function of buffering and vibration absorption, which can reduce vibration and noise during transmission, and create a quiet and comfortable rehabilitation training environment for users. For rehabilitation training movements that require precise transmission ratios and transmit large torque, gear drive is more suitable. Gear drive has high transmission efficiency and can ensure accurate power transmission, making rehabilitation training movements more accurate and effective. Multi-chain multi-stage transmission is suitable for situations where a large speed ratio adjustment is required and high requirements are placed on transmission stability and reliability. It provides strong support for complex rehabilitation training programs. This diverse selection of transmission modes enables fitness and medical rehabilitation equipment to better adapt to the personalized needs of different users and improves the versatility and applicability of the equipment.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example 1, please refer to Figures 1 to 6 As shown, the fitness medical rehabilitation equipment using the resistance power box includes: A fixing bracket 1 is provided, a mounting portion 2 is welded on the left side of the fixing bracket 1, and a control panel 3 is fixed on the top of the mounting portion 2 by bolts; the electrical components of the fitness medical rehabilitation equipment are electrically controlled by the control panel 3 on the top of the mounting portion 2, thereby realizing flexible control of the fitness medical rehabilitation equipment.

[0021] The lifting movable seat cushion 4 is movably arranged in the middle of the fixed bracket 1; by setting the lifting movable seat cushion 4 at different heights, the fitness medical rehabilitation equipment can be adapted to people of different heights, thereby improving the applicability of the fitness medical rehabilitation equipment.

[0022] The adjustable backrest 5 is rotatably arranged on the right side of the fixed bracket 1, wherein the bottom of one side of the adjustable backrest 5 is rotatably connected to one side of the fixed bracket 1; by adjusting the adjustable backrest 5 to different angles, the adjustable backrest 5 can fit the backs of people of different body shapes, thereby further improving the applicability of the fitness medical rehabilitation equipment.

[0023] Rehabilitation transmission unit 8, rehabilitation transmission unit 8 is symmetrically arranged on the front and rear sides of the fixed bracket 1, and the right ends of the two rehabilitation transmission units 8 are each provided with a resistance power box 6, one side of the resistance power box 6 is also fixedly provided with a heat sink 7, and the heat sink 7 is provided inside with a heat dissipation fan 27; the rehabilitation transmission unit 8 is controlled to swing through the resistance power box 6, and the power output of the resistance power box 6 is controlled and adjusted in conjunction with the control panel 3, so that the fitness medical rehabilitation equipment can adjust the power of rehabilitation training according to people in different states, which not only avoids the discomfort of people caused by excessive rehabilitation power, but also avoids the problem of poor rehabilitation effect caused by too small rehabilitation power.

[0024] It also needs to be further explained that a limit sleeve 10 is fixedly provided on one side of the fixed bracket 1, and a connecting sleeve rod 9 is movably provided inside the limit sleeve 10, and the top end of the connecting sleeve rod 9 is fixedly connected to the bottom of the lifting movable seat cushion 4.

[0025] A rotating connecting block 11 is fixedly provided on one side of the limiting sleeve 10, and a limiting elastic block 12 is rotatably provided on one side of the rotating connecting block 11, a spring 13 is fixedly provided below one side of the limiting elastic block 12, and the other end of the spring 13 is fixedly connected to one side of the limiting sleeve 10, a limiting column 14 is fixedly provided above one side of the limiting elastic block 12, and a through groove 15 is also provided above one side of the limiting sleeve 10, and a plurality of limiting holes 16 matching the limiting columns 14 are provided on one side of the connecting sleeve rod 9.

[0026] It should be noted that when adjusting the height of the lifting and movable seat cushion 4, by pressing the limiting elastic block 12 toward one side of the limiting sleeve 10, when the spring 13 is deformed, the limiting column 14 on one side of the limiting elastic block 12 withdraws from the inside of the limiting hole 16. At this time, the position of the connecting sleeve rod 9 inside the limiting sleeve 10 can be adjusted up and down. After the height of the lifting and movable seat cushion 4 is adjusted to a reasonable height, the limiting elastic block 12 is released. After the spring 13 recovers, the limiting column 14 on one side of the limiting elastic block 12 is passed through the through groove 15 and inserted into the limiting hole 16 on one side of the connecting sleeve rod 9 to complete the limiting connection between the limiting sleeve 10 and the connecting sleeve rod 9, and complete the height adjustment operation of the lifting and movable seat cushion 4, so that the fitness, medical and rehabilitation equipment can be adapted to people of different heights for use.

[0027] It also needs to be further explained that an adjusting motor 17 is fixedly provided on one side of the fixed bracket 1, and an adjusting gear 18 is fixedly provided on one end of the output shaft of the adjusting motor 17, a back plate adjustment block 19 is fixedly provided on the right side of the adjustable backrest 5, and one side of the back plate adjustment block 19 is slidingly connected to the inside of the fixed bracket 1, an external tooth groove is provided at the bottom of the back plate adjustment block 19, and the bottom of the back plate adjustment block 19 is meshed with the tooth surface of the adjusting gear 18 for transmission, a micro electric cylinder 20 is also fixedly provided on one side of the fixed bracket 1, and a plurality of positioning holes 21 are provided inside the back plate adjustment block 19, and the interiors of the plurality of positioning holes 21 are matched with the driving shaft size of the micro electric cylinder 20.

[0028] It should be noted that when the angle of the adjustable backrest 5 is adjusted, the adjusting gear 18 is controlled to rotate by adjusting the output shaft of the motor 17, and the adjusting gear 18 drives the back plate adjustment block 19 to slide inside the fixed bracket 1, thereby rotating one side of the adjustable backrest 5. After the adjustable backrest 5 is adjusted to a suitable angle, the driving end of the micro electric cylinder 20 and the positioning hole 21 inside the back plate adjustment block 19 are used to cooperate and connect, thereby ensuring the connection stability between the back plate adjustment block 19 and the fixed bracket 1.

[0029] Furthermore, the rehabilitation transmission unit 8 includes a rotating bracket 23, a rotating connecting seat 22 is fixedly provided on the front and rear sides of the fixed bracket 1, and the rotating bracket 23 is rotatably provided inside the two rotating connecting seats 22, the tops of the two rotating brackets 23 are fixed with fitness handles 24 by bolts, and the right sides of the two rotating brackets 23 are movably provided with connecting movable arms 25, and the right ends of the two connecting movable arms 25 are movably provided with rotating parts 26, a power transmission rod 28 is rotatably provided on the upper part of the resistance power box 6, and the bottoms of the two rotating parts 26 are respectively fixedly connected to the two ends of the power transmission rod 28.

[0030] It should be noted that when training with fitness medical rehabilitation equipment, the power transmission rod 28 is controlled to rotate by the resistance power box 6, and the two ends of the power transmission rod 28 are used to drive the two rotating parts 26 to rotate. The two rotating parts 26 drive the two rotating brackets 23 to swing left and right through the two connecting movable arms 25. The user performs rehabilitation training by holding the fitness handles 24 with both hands. According to different training requirements, the power output of the resistance power box 6 is controlled and adjusted using the control panel 3 to ensure the rehabilitation training effect of the user.

[0031] In a specific embodiment, in the present invention, in terms of control, the control panel 3 arranged on the top of the mounting portion 2 provides a convenient operating interface for the user. Through this control panel, the electrical components in the fitness medical rehabilitation equipment, such as the resistance power box 6, the adjustment motor 17, etc., can be electrically controlled. This centralized control method allows the user to easily adjust the various functions of the equipment without complicated operating steps.

[0032] The cooperation between the resistance power box 6 and the control panel 3 realizes personalized rehabilitation training power adjustment. During the rehabilitation training process, people in different states have different needs for rehabilitation power. For people who are relatively weak in the early stage of rehabilitation, too much rehabilitation power may cause physical discomfort or even injury; while for people with good rehabilitation progress and improved physical fitness, too little rehabilitation power is difficult to achieve the ideal rehabilitation effect. Through the precise control of the power output of the resistance power box 6 by the control panel 3, the rehabilitation training power can be tailored for people in different states to ensure the safety and effectiveness of the training.

[0033] The design of the lifting and movable seat cushion 4 fully considers the usage needs of people of different heights. It is connected to the fixed bracket 1 through a limit sleeve 10 and a connecting sleeve rod 9. When adjusting the height, press the limit elastic block 12 to make the limit column 14 withdraw from the limit hole 16 of the connecting sleeve rod 9. At this time, the position of the connecting sleeve rod 9 in the limit sleeve 10 can be easily adjusted up and down. After adjusting to the appropriate height, release the limit elastic block 12. Under the action of the spring 13, the limit column 14 is reinserted into the corresponding limit hole 16 to achieve precise positioning. This design is not only simple to operate, but also can meet the usage needs of people of different heights, greatly improving the applicability of the equipment.

[0034] The angle adjustment structure of the adjustable backrest 5 also fully considers the use needs of people of different heights. The adjustment motor 17 drives the adjustment gear 18 to rotate through the output shaft, and meshes with the outer tooth groove at the bottom of the back plate adjustment block 19 for transmission, thereby driving the back plate adjustment block 19 to slide inside the fixed bracket 1 to achieve the angle change of the adjustable backrest 5. When adjusted to a suitable angle, the driving end of the micro-electric cylinder 20 is inserted into the positioning hole 21 inside the back plate adjustment block 19 to ensure that the backrest will not shake at will during use, and can stably fit the backs of people of different body shapes, providing comfortable support for users, and further improving the applicability and use experience of the equipment; the structural design of the rehabilitation transmission unit 8 provides a scientific and effective exercise method for rehabilitation training. The rotating connecting seat 22 on the front and rear sides of the fixed bracket 1 supports the rotating bracket 23 so that it can rotate flexibly. When the power transmission rod 28 inside the resistance power box 6 rotates, it drives the rotating parts 26 at both ends to rotate, and then drives the rotating bracket 23 to swing left and right through the connecting movable arm 25. The user holds the fitness handle 24 with both hands, and targeted rehabilitation training can be carried out in this process.

[0035] This design simulates the natural movement of the human body, which helps the user to restore the motor function and coordination of the limbs. At the same time, according to different training requirements, the power output of the resistance power box 6 can be adjusted through the control panel 3, which can provide users with training of different intensities to meet the training needs of different stages from the early to the late stages of rehabilitation, thereby ensuring the maximization of the rehabilitation training effect.

[0036] Moreover, the overall structural design of the fitness medical rehabilitation equipment fully considers stability and reliability. In the height adjustment structure of the lifting movable seat cushion 4, the cooperation between the limit column 14 and the limit hole 16, and the resetting effect of the spring 13 on the limit elastic block 12 ensure that the seat cushion will not loosen or slide down accidentally during use; in the angle adjustment structure of the adjustable backrest 5, the cooperation between the micro electric cylinder 20 and the internal positioning hole 21 of the back plate adjustment block 19 can provide a strong locking force after the backrest is adjusted to a suitable angle, thereby ensuring the stability of the backrest. In addition, the various components, such as bolt connections and meshing transmission, have been carefully designed to ensure that the entire equipment has a stable structure during use and can withstand certain external forces, thereby providing users with a safe and reliable training environment and reducing safety hazards caused by equipment structural problems.

[0037] Example 2, please refer to Figures 7 to 11 As shown, this embodiment specifically discloses the structural composition of the resistance power box used for the above-mentioned fitness medical rehabilitation equipment. The resistance power box 6 includes: a drive housing 29 and a drive motor 30. One end of the output shaft of the drive motor 30 extends to the interior of the drive housing 29, and both ends of the power transmission rod 28 extend to both sides of the drive housing 29 respectively.

[0038] As the first component structure of the resistance power box 6, a pulley 2 32 is fixedly provided at one end of the output shaft of the driving motor 30, a pulley 1 31 is fixedly provided on the surface of the power transmission rod 28, and the surfaces of the pulley 1 31 and the pulley 2 32 are connected through a transmission belt 33.

[0039] As the second component structure of the resistance power box 6, a driving gear 34 is fixedly provided at one end of the output shaft of the driving motor 30, a driven gear 35 is fixedly provided on the surface of the power transmission rod 28, and the tooth surface of the driving gear 34 meshes with the tooth surface of the driven gear 35 for transmission.

[0040] As the third component structure of the resistance power box 6, a mounting frame 36 is fixedly provided inside the driving housing 29, a driven gear 37 is fixedly provided at one end of the output shaft of the driving motor 30, and a transmission gear ring 38 is rotatably provided above the driven gear 37, and the tooth surface of the driven gear 37 and the tooth surface of the transmission gear ring 38 are meshed and transmitted through a chain 39, a synchronous shaft 40 is fixedly provided inside the transmission gear ring 38, and the right end of the synchronous shaft 40 extends to the right side of the mounting frame 36, a driven gear 2 41 is fixedly provided on the right end of the synchronous shaft 40, and a transmission gear ring 2 42 is rotatably provided above the driven gear 2 41, and the tooth surface of the driven gear 2 41 and the tooth surface of the transmission gear ring 2 42 are meshed and transmitted through a chain 2 43 meshing transmission, a synchronization shaft 24 is fixedly provided inside the transmission gear ring 2 42, and the left end of the synchronization shaft 24 extends to the left side of the transmission gear ring 1 38, a driven gear 3 45 is fixedly provided on the left end of the synchronization shaft 24, and a transmission gear ring 3 46 is rotatably provided above the driven gear 3 45, and the tooth surface of the driven gear 3 45 and the tooth surface of the transmission gear ring 3 46 are meshed and transmitted through a chain 3 47, the interior of the transmission gear ring 3 46 is fixedly connected to the surface of the power transmission rod 28, and one end of the power transmission rod 28 passes through the interior of the mounting frame 36, wherein the diameters of the driven gear 1 37, the driven gear 2 41 and the driven gear 3 45 increase successively, and the diameters of the transmission gear ring 1 38, the transmission gear ring 2 42 and the transmission gear ring 3 46 are the same.

[0041] It should be noted that the resistance power box 6 proposed in the present invention provides three different transmission modes, namely, belt transmission, gear transmission and multi-chain multi-stage transmission. Different use scenarios and rehabilitation training needs have different requirements for transmission characteristics. In some environments with high requirements for transmission stability and strict noise restrictions, belt transmission (a transmission structure composed of pulley 1 31, pulley 2 32 and transmission belt 33) is a good choice. Belt transmission has the function of buffering and vibration absorption, which can reduce vibration and noise during the transmission process, and create a quiet and comfortable rehabilitation training environment for users. For rehabilitation training actions that require precise transmission ratios and transmit large torque, gear transmission (meshing transmission of driving gear 34 and driven gear 35) is more suitable. Gear transmission has high transmission efficiency and can ensure accurate transmission of power, making the rehabilitation training actions more accurate and effective. Multi-chain multi-stage transmission mode is suitable for situations where a large speed ratio adjustment is required and high requirements are placed on transmission stability and reliability, providing strong support for complex rehabilitation training programs. This diverse selection of transmission modes enables fitness and medical rehabilitation equipment to better adapt to the personalized needs of different users and improves the versatility and applicability of the equipment.

[0042] Different transmission methods have their own advantages in terms of stability and reliability. Belt transmission relies on the friction between the belt and the pulley to transmit power. When encountering an overload, the belt will slip, thereby avoiding damage to the drive motor 30 and other transmission components due to overload, and playing a certain protective role. In the gear transmission, the teeth of the driving gear 34 and the driven gear 35 mesh with each other, which can accurately transmit power. The transmission process is stable and there will be no slippage, which ensures the accuracy and consistency of the rehabilitation training movements. In the multi-chain multi-stage transmission method, the meshing transmission between the chain and the gear ring and gear has a high transmission efficiency and load-bearing capacity. At the same time, the structure of the chain transmission is relatively simple, easy to maintain, and can maintain good working performance in long-distance transmission and harsh working environments. Through the combination of multiple transmission methods, the stability and reliability of power transmission can be guaranteed in different rehabilitation training scenarios to ensure the smooth progress of rehabilitation training.

[0043] The multi-chain multi-stage transmission mode (a multi-stage transmission structure composed of a driven gear 37, a transmission gear ring 38, a chain 39, etc.) provides more speed options for rehabilitation training. Through the combination of gears and gear rings of different sizes, a wide range of speed ratio adjustment can be achieved, which means that during the rehabilitation training process, the speed and torque output of the power transmission rod 28 can be flexibly adjusted according to the user's physical condition and rehabilitation progress; for patients in the early stages of rehabilitation, the power transmission rod 28 can be used at a lower speed and a smaller torque output for relatively gentle rehabilitation training; as the patient's physical condition gradually improves, the speed and torque of the power transmission rod 28 can be gradually increased to increase the intensity and difficulty of the training. This adjustability and flexibility enables rehabilitation training to be carried out more scientifically and reasonably, and helps to improve the effect of rehabilitation training.
