[0002] The present invention specifically relates to an intelligent chiropractic pressure device, belonging to the technical field of medical rehabilitation equipment. Background Art

[0003] Chiropractic compression is a treatment method for orthopedic spine-related diseases. The operation is mainly performed on a chiropractic compression bed, in which the chiropractic compression device is the core key component. The chiropractic compression device usually uses a mechanical lifting mechanism to lift the bed board to meet the requirements of compression. During treatment, the bed board is first raised to a certain height, and the height is maintained under the resistance of the damping force. Then, downward pressure is applied to overcome the damping force so that the bed board drops instantly again to achieve the compression effect. Existing compression beds have defects such as feeling hard, loud noise, inconvenient pressure adjustment, and the need for manual resetting during use. After compression, it is inconvenient for the bed board to automatically rise after it is lowered, and the damping size of the compression component needs to be manually adjusted. Compression treatment is usually judged based on the therapist's experience, and the damping force cannot be automatically adjusted according to the patient's weight.

DETAILED DESCRIPTION

[0024] The present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, an intelligent chiropractic pressure device includes, from bottom to top, a first support plate 1, a second support plate 2 and a third support plate 3. The three support plates are arranged in parallel and spaced apart. A bed board 4 is fixedly arranged on the third support plate 3, and the patient can lie or lie on the bed board 4 to receive treatment. Four weighing sensors 5 and four small guide columns 21 are arranged between the second support plate 2 and the third support plate 3. The weighing sensor is an existing product on the market. The base of the weighing sensor is fixedly connected to the second support plate, and the upper surface of the inner column of the weighing sensor is fixedly connected to the third support plate. The weighing sensor 5 can sense the pressure of the patient's weight on the bed board. The pressure device also includes a control device, which is not shown in the figure. The weighing sensor is electrically connected to the control device.

[0026] A pressure module is arranged on the first support plate 1, and the pressure module includes a core block 8. A vertical shaft hole penetrating up and down is arranged at the center of the core block 8. A supporting main shaft 87 is arranged in the vertical shaft hole. The supporting main shaft 87 can slide up and down in the vertical direction relative to the core block 8; a horizontal channel is also arranged on the core block, and the horizontal channel is vertically cross-connected with the vertical shaft hole. A first damping component and a second damping component are arranged in the horizontal channel. The first damping component and the second damping component are symmetrically arranged on both sides of the supporting main shaft. The first damping component includes a first damping adjustment rod 81, a first spring 82, and a first steel ball 83. The second damping component includes a second damping adjustment rod 84, a second spring 85, and a second steel ball 86. The first damping adjustment rod 81, the first damping adjustment rod 82, and the first damping adjustment rod 83 are provided with a first damping adjustment rod 84, a second spring 85, and a second steel ball 86. A spring 82 and a first steel ball 83 are located on the same side of the support spindle 87, and a second damping adjustment rod 84, a second spring 85 and a second steel ball 86 are located on the other side of the support spindle 87. Two groups of damping components are symmetrically arranged on both sides of the support spindle. The damping adjustment rod can compress the spring by moving inward, and the spring squeezes the support spindle through the steel balls. Two rows of multiple arc-shaped pits 871 matching the steel balls are arranged on the surface of the support spindle 87 along its axial direction. The pits can accommodate the steel balls. The spring squeezes the steel balls to embed them into the pits on the support spindle to press the support spindle. When the support spindle slides up and down to make the steel balls detach from the pits, a certain resistance needs to be overcome, that is, the horizontal squeezing force of the steel balls on the support spindle forms a damping force when the support spindle is performing a lifting movement.

[0027] In order to realize automatic adjustment of the damping force of the compression module, a damping adjustment module is also provided on the first support plate 1, and the damping adjustment module includes a driving mechanism and a displacement detection module 10. The driving mechanism is used to drive the horizontal lateral movement of the two damping adjustment rods, and the displacement detection module is used to detect the deformation of the spring, which is a displacement sensor. The driving mechanism and the displacement detection module are both electrically connected to the control system. Specifically, the driving mechanism includes a second motor 101, and a driving gear 102 is fixedly connected to the output shaft of the second motor through a coupling; a first fixed seat 105 and a second fixed seat 106 are also fixedly installed on the first support plate 1, and the two fixed seats are separated on both sides of the core block 8 of the compression module. The two fixing seats are connected by a rotating shaft 109, which can rotate relative to the fixing seats. A first wide gear 103 and a second wide gear 107 are fixedly sleeved at both ends of the rotating shaft 109, wherein the first wide gear 103 is meshed with the driving gear 102, and the two wide gears can rotate synchronously under the drive of the second motor; in addition, threaded holes are provided on the two fixing seats 105 and 106, and threads are provided on the outer ends of the two damping adjustment rods 81 and 84. The thread directions of the first damping adjustment rod and the second damping adjustment rod are opposite, one is left-handed and the other is right-handed, so that the threaded portion of the first damping adjustment rod 81 is inserted into the second damping adjustment rod 84. A threaded hole of a fixing seat 15 is threadedly connected to the first fixing seat 15, and a threaded portion of the second damping adjustment rod 84 is inserted into the threaded hole of the second fixing seat 106 and is threadedly connected to the second fixing seat 106. A first passive gear 104 is also fixedly sleeved on the first damping adjustment rod 84, and the first wide gear 103 is located between the driving gear 102 and the first passive gear 104, and the first wide gear 103 is respectively meshed with the driving gear 102 and the first passive gear 104; a second passive gear 108 is also fixedly sleeved on the second damping adjustment rod 84, and the second passive gear 108 is meshed with the second wide gear 107. In this way, when the second motor drives the driving gear 102 to rotate, the two wide gears 103 and 107 can synchronously drive the two passive gears 104 and 108 to rotate, and the two passive gears respectively drive the two damping adjustment rods 81 and 84 to rotate. Because the outer ends of the two damping adjustment rods are reversely threadedly connected to the two fixed seats and the two fixed seats remain stationary, when the two damping adjustment rods rotate, they themselves will move horizontally along their axial directions, synchronously approaching each other or synchronously moving away from each other. When the two damping adjustment rods approach the supporting main shaft synchronously, the two springs will be compressed respectively to increase the detent damping force. When the two damping adjustment rods move away from the supporting main shaft synchronously, the two springs will be stretched to reduce the detent damping force.

[0028] In order to detect the deformation of the spring, a connecting plate 90 is fixedly connected at the end of the first damping adjustment rod 81 near the first spring 82, and the connecting plate 90 passes through the slot 89 on the core block 8 and is connected to the displacement detection module 10. In this way, the movement of the connecting plate is synchronized with the adjustment rod, and the displacement of the connecting plate in the slot of the core block is given by the detection module. This displacement is also equivalent to the deformation of the spring. The elastic force of the spring can be calculated based on the inherent elastic coefficient of the spring itself. The elastic force is proportional to the damping force of the compression module, and then the damping force of the compression module is obtained. A limit position sensor 110 is also provided on the first support plate. When the connecting plate 90 moves and contacts the limit position sensor 110, it means that the spring has reached the limit compression amount that can be restored to its original state and cannot be further compressed. At this time, the limit position sensor 110 sends a signal to the control system, and the control system controls the second motor of the damping adjustment module to stop, which plays a protective role.

[0029] The upper end of the support main shaft 87 is fixedly connected to the second support plate 2 to form a support for the second support plate 2, and the lower end of the support main shaft 87 freely passes through the lower surface of the first support plate 1. Four guide pillars 7 are evenly spaced and fixedly arranged around the support main shaft on the lower surface of the second support plate 2. Guide holes are arranged on the first support plate corresponding to the guide pillars. The guide pillars fit in the guide holes and can pass through the guide holes. The guide pillars provide a guide for the lifting and lowering of the second support plate and prevent rotation. A polyurethane column 71 is fixedly arranged on the upper periphery of the guide pillar 7, and a nylon pad 72 is fixedly installed around the guide hole on the first support plate, so that when the guide pillar 7 descends, the polyurethane column 71 will hit the nylon pad 72, which can buffer and reduce the impact noise. At the same time, two shock absorbers 6 are installed between the first support plate 1 and the second support plate 2, and their function is to reduce the vibration during the sudden pressure. A travel switch 9 is also installed on the first support plate 1. The travel switch can give a signal that the second support plate is in a raised state or a lowered state. The travel switch is electrically connected to the control device.

[0030] A driving module for driving the support spindle 87 to rise is fixedly installed on the lower surface of the first support plate 1; as a specific embodiment, the driving module includes a first motor 11, the first motor 11 is electrically connected to the control device, the output shaft of the first motor is in the horizontal direction, and a cam 12 is fixedly installed on the output shaft of the first motor, and the cam 12 is located directly below the support spindle 87. The cam shown in the figure rotates one circle to lift the support spindle upward twice. A top wheel 88 is also rotatably installed at the lower end of the support spindle 87, and the function of the top wheel is to reduce the friction force when the cam lifts the support spindle upward. In order to detect the angle state of the maximum diameter of the cam, a sensor sheet 13 is also installed on the motor output shaft outside the cam, and the angular position relationship between the sensor sheet 13 and the cam 12 can be adjusted. After adjustment, they are relatively fixed, and the sensor sheet 13 rotates synchronously with the cam 12. A sensor switch 14 is also fixedly installed on the lower surface of the first support plate 1, and the sensor switch can be a photoelectric switch. The cooperation between the sensor sheet 13 and the sensor switch 14 can detect the movement angle of the cam and determine whether the maximum diameter of the cam passes directly below the support spindle. For example, when the supporting spindle is descending, the maximum diameter of the cam needs to deviate from the bottom of the supporting spindle to prevent the cam from hindering the descent of the supporting spindle. The induction switch is electrically connected to the control device.

[0031] In summary, the above-mentioned intelligent chiropractic pressure device based on user identification includes a first motor, a second motor, a displacement detection module (displacement sensor), two damping adjustment rods, a weighing sensor (segment gravity sensor), a travel switch, an inductive switch (photoelectric switch) and a control system. The displacement sensor is used to obtain the displacement distance of the damping adjustment rod, and the segment gravity sensor is used to obtain the gravity of the chiropractic segment of the patient lying on the chiropractic bed. The control system is electrically connected to the displacement sensor, segment gravity sensor, travel switch, inductive switch, two motors, etc.

[0032] An intelligent chiropractic pressing method based on user identification, using the above-mentioned pressing device, has the following steps: The first step is to calculate the displacement of the damping adjustment rod according to the patient's weight: the patient lies on or lies prone on the bed board, and the weighing sensor sends the patient's segment gravity to the control system. The control system obtains the damping force of the pressure module according to the segment gravity and a certain algorithm, and converts the damping force into the elastic force required by the spring, and obtains the displacement of the damping adjustment rod according to the elastic force of the spring; The second step is to adjust the damping force of the pressure module according to the displacement: the second motor is started, and its output rotation number and angle are controlled to drive the damping adjustment rod to move. When the displacement sensor detects that the movement of the damping adjustment rod reaches the required displacement, the second motor stops, and the damping force setting of the pressure module is completed; The third step is to raise and reset the support spindle: start the first motor to drive the cam to lift the support spindle of the pressure module upward, and the support spindle is kept in the raised state under the damping of the spring force. When the induction switch detects that the maximum diameter of the cam completely deviates from the bottom of the support spindle by a certain angle, the first motor stops; The fourth step is pressing: the doctor presses down on the specific part of the patient. The downward force formed by the doctor's pressing pressure and the patient's gravity overcomes the damping force of the pressing module, causing the patient and the supporting main shaft to fall down instantly to form a pressing treatment. The fifth step is that when the travel switch detects that the supporting spindle has dropped into place, it delays for a certain period of time, then starts the first motor again to drive the cam to lift the supporting spindle upward and reset it, repeats the above third step and subsequent steps, and performs the second compression treatment, and so on.

[0033] The algorithm in the first step includes: The controller calculates the spring force according to the displacement and the segment gravity; The controller calculates the damping force according to the spring force; The controller calculates and adjusts the output rotation amount of the second motor according to the preset detonation pressure; The calculation formula includes: F1 = kX, where F1 is the calculated spring force, X is the displacement, and k is the elastic coefficient; F2=n*F1, F2 is the damping force, n is a positive integer (n=1 means there is one set of damping components, n=2 means there are two sets of damping components); F3=F2-G, F3 is the pressure applied by the physician, G is the patient's positional gravity; X=y(θ*S) / 2π, θ is the rotation angle of the second motor, S is the pitch of the adjustment rod, and y is the transmission coefficient of the gear set; θ=(F3+G)*2 π / (n*k *y*S), θ is the output rotation angle of the second motor.

[0034] When the present invention is in use, first the patient lies on the bed board, and the patient's body parts are in contact with the bed board. The weighing sensor will sense the patient's weight. Based on the weight data, the control system will automatically calculate the resistance required for the compression according to the internal algorithm, so that the damping force is quantified. The required compression of the spring can be converted according to the resistance. With the compression of the spring, the number of rotations of the motor can be controlled. In this way, after the motor is started, the damping adjustment rod can be driven to move through the gear transmission. After the adjustment rod moves, the spring is quantitatively compressed. The spring squeezes the supporting spindle through the steel ball, thereby changing the resistance of the supporting spindle when it is lifting and lowering. In this way, the therapist can basically use the same compression strength each time during the compression treatment, which reduces the therapist's dependence on clinical experience and improves the treatment effect. At the same time, the first motor drives the cam to repeatedly lift the supporting spindle and the patient, and multiple rounds of compression treatment are performed, thereby improving the automation level of the device.
