[0001] The present invention relates to the technical field of chiropractic pressing equipment, and in particular to an electric pressing equipment and a control method for the electric pressing equipment. Background Art

[0002] A chiropractic pressing bed is a special equipment for lying-down spinal rehabilitation, mainly used for manual treatment of the spine, and can also be used for manual treatment of other parts of the body; the equipment is configured with support beds corresponding to different parts such as the head, cervical vertebrae, thoracic vertebrae, lumbar vertebrae, pelvis, etc., and a pressing and sliding device corresponding to each support bed. The patient lies on the support bed of the chiropractic pressing bed, and the medical staff exerts force on the diseased part of the patient's body, so that the pressing and sliding device controls the support bed corresponding to the diseased part of the patient to produce an instantaneous drop, so that the diseased part of the patient is subjected to an instantaneous dropping pressing force, thereby achieving the purpose of mechanical correction; for different types of vertebral dislocations, the pressing and sliding device can achieve non-rotating flashing correction of the entire spine by changing different body positions and pushing positions; and after each pressing treatment is completed, the support bed that has dropped and pressed needs to be raised.

[0003] However, the current conventional chiropractic pressing bed requires a large amount of physical strength from medical staff during the treatment process, and the operation process is cumbersome. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric pressing equipment and a control method for the electric pressing equipment, which can reduce the physical consumption of medical staff during pressing treatment to a certain extent, and on the other hand, simplify the operation process of pressing treatment.

[0005] To solve the above technical problems, the present invention provides an electric pressing equipment, including a support plate for supporting the human body; a pressure sensor for detecting the downward pressure received by the support plate; an electric support assembly for providing an upward supporting force for the support plate;

[0006] When the downward pressure received by the support plate reaches a preset pressure threshold, the electric support assembly interrupts providing the upward supporting force for the support plate, so that the support plate drops and presses.

[0007] When the duration of the electric support assembly interrupting providing the upward supporting force for the support plate reaches a preset duration, the electric support assembly drives the support plate to move upward to a set height.

[0013] When the support plate is pulled down by a downward pressure to pull the end of the traction rope, the traction rope generates a downward pressure on the pressure transmission member, and the pressure transmission member presses down on the pressure sensor so that the pressure sensor detects corresponding pressure data;

[0014] When it is determined according to the pressure data detected by the pressure sensor that the downward pressure borne by the support plate is greater than the preset pressure threshold, the electric tractor releases the traction rope to freely disengage;

[0015] When the duration for which the electric tractor releases the traction rope reaches the preset duration, the electric tractor winds and contracts the traction rope to control the traction rope to pull the main support column upward.

[0016] In an optional embodiment of the present application, the pressure sensor is a diaphragm pressure sensor;

[0023] And a spring member is sleeved on the side support column, and the spring member is located between the support seat and the support plate.

[0025] Real-time collect the pressure data of the support plate collected by the pressure sensor in the electric punching device;

[0026] Judge whether the downward pressure borne by the support plate is greater than a preset pressure threshold according to the pressure data;

[0027] If so, control the electric support assembly in the electric punching device to interrupt providing an upward support force for the support plate;

[0028] When the duration of the electric support assembly interrupting to provide an upward support force for the support plate reaches a preset duration, control the electric support assembly to drive the support plate to move upward to a set height.

[0029] In an alternative embodiment of the present application, judging whether the downward pressure borne by the support plate is greater than a preset pressure threshold according to the pressure data includes:

[0030] Use the moving average filtering algorithm to perform average filtering operations on each of the pressure data within the sliding window including the current pressure data to obtain the punching pressure borne by the support plate;

[0031] Judge whether the punching pressure is greater than a preset pressure threshold. If so, the downward pressure borne by the support plate is greater than the preset pressure threshold.

[0032] In an alternative embodiment of the present application, before using the moving average filtering algorithm to perform average filtering operations on each of the pressure data within the sliding window including the current pressure data, it further includes:

[0033] Perform an absolute value operation on the difference between the current pressure data and the pressure data measured at the previous adjacent moment to obtain an absolute value of the pressure difference;

[0034] If the absolute value of the pressure difference is greater than a preset deviation value, set the size of the sliding window to the first window length; wherein, the preset deviation value is one-tenth of the difference between the preset pressure threshold and the body weight pressure;

[0035] If the absolute value of the pressure difference is not greater than a preset deviation value, it is determined whether the number of pressure data belonging to the pressure data in the steady shock region of the sudden pressure is greater than the second window length. If so, the size of the sliding window is set to the second window length. If not, the size of the sliding window is set to the size of the number of data.

[0036] Among them, the pressure data belonging to the steady shock region of the sudden pressure includes the current pressure data and a plurality of continuously collected pressure data collected before the current pressure data, and the absolute value of the pressure difference corresponding to each pressure data belonging to the steady shock region of the sudden pressure is not greater than the preset deviation value; the first window length is less than the second window length.

[0037] An electric sudden pressure device and a control method for an electric sudden pressure device provided by the present invention include a support plate for supporting a human body; a pressure sensor for detecting the downward pressure received by the support plate; an electric support assembly for providing an upward support force for the support plate; when the downward pressure received by the support plate reaches a preset pressure threshold, the electric support assembly interrupts providing an upward support force for the support plate so that the support plate falls suddenly; when the duration for which the electric support assembly interrupts providing an upward support force for the support plate reaches a preset duration, the electric support assembly drives the support plate to move upward to a set height.

[0038] In the electric sudden pressure device of the present application, a pressure sensor capable of detecting the downward pressure received by the support plate is provided below the support plate, and the pressure sensor is used to sense and detect the action of manual pressing by medical staff; on this basis, a corresponding electric support assembly is provided to provide an upward support force for the support plate, and when the pressure sensor measures that the downward pressure received by the support plate is greater than a preset pressure threshold, the electric support assembly immediately removes its support force on the support plate, so that the support plate can fall suddenly and quickly, thereby realizing the sudden pressure treatment of the body on the support plate. It can be seen that the sudden fall of the support plate in the present application is realized by the electric support assembly removing the support force, and it is not necessary for medical staff to apply too much downward pressure. Therefore, to a certain extent, the physical strength of medical staff is saved; in addition, after the support plate completes the sudden fall in the present application, the electric support assembly can also automatically drive the support plate to rise, saving the action of the patient or medical staff to operate the support plate to rise, that is, simplifying the operation process of the device.

Obviously, the following drawings are only some embodiments of the present invention.

[0044] At present, in the process of realizing the support bed body falling and impacting in the conventional chiropractic impact bed, a resistance component is mostly arranged below the support bed body. When the magnitude of the downward pressure received by the support bed body reaches a certain pressure magnitude, the resistance applied by the resistance component to the support bed body can be overcome and it can fall downward; and to overcome this falling resistance, there are inevitably requirements for the downward pressure applied by the medical staff, which also requires more physical strength of the medical staff.

[0045] In addition, after the support bed body falls, it needs to be raised to perform the next treatment. That is to say, in the whole treatment process, the support bed body needs to be repeatedly pressed down and raised, making the whole treatment operation process very cumbersome.

[0046] Therefore, the present application provides a technical solution that can reduce the physical strength requirements for medical staff during the chiropractic impact treatment process, and can automatically rise after the support bed body falls, thereby simplifying the operation process of medical staff.

[0047] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figure 1 and Figure 2 shown, Figure 1 Structural schematic diagram of the electric impact device provided by the embodiment of the present application; Figure 2 Structural schematic diagram of the electric traction device provided by the embodiment of the present application.

[0049] In a specific embodiment of the present application, the electric impact device may include:

[0050] A support plate 10 for supporting a human body; a pressure sensor 40 for detecting the downward pressure received by the support plate 10; an electric support assembly for providing an upward supporting force for the support plate 10;

[0051] When the downward pressure received by the support plate 10 reaches a preset pressure threshold, the electric support assembly interrupts providing the upward supporting force for the support plate 10 so that the support plate 10 falls and presses suddenly;

[0052] When the duration for which the electric support assembly interrupts providing the upward supporting force for the support plate 10 reaches a preset duration, the electric support assembly drives the support plate 10 to move upward to a set height.

[0053] It can be understood that the support plate 10 in this embodiment is also the support bed body in the chiropractic pressing bed for supporting the human body. In a complete chiropractic pressing bed, generally there are multiple support plates 10 corresponding to different positions of the human body, and a corresponding pressure sensor 40 and electric support assembly are arranged below each support plate 10; the upward and downward pressing of each support plate 10 are completed independently, and the control methods and structures of the upward and downward movement of each support plate 10 can be exactly the same.

[0054] On this basis, a pressure sensor 40 and an electric support assembly are configured for the support plate 10 in this embodiment. During the treatment of a patient, medical staff apply a downward pressure to the human body lying on the support plate 10, and this downward pressure can be transmitted to the support plate 10 through the human body, that is, the support plate 10 bears a suddenly downward pressure; and the pressure sensor 40 can detect in real time the downward pressure borne by the support plate 10. Thus, based on the pressure data detected by the pressure sensor 40, it can be determined whether the magnitude of the pressure borne by the support plate 10 exceeds the preset pressure threshold. When the magnitude of the pressure borne by the support plate 10 is greater than the preset pressure threshold, it can be determined that the medical staff has performed a downward pressing operation, otherwise it is considered that the medical staff has not performed a downward pressing operation. In practical applications, the pressure sensor 40 can be considered to be directly arranged on the upper surface of the support plate 10 or can be connected to the support plate 10 through other intermediate components. In short, as long as the greater the downward pressure received by the support plate 10, the corresponding change in the pressure data detected by the pressure sensor 40, no specific limitation is made in this embodiment.

[0055] In addition, the support plate 10 is further connected with an electric support assembly; the electric support assembly can provide an upward supporting force for the support plate 10. Before the treatment starts, the electric support assembly supports the support plate 10 to maintain at a set height. When the pressure sensor 40 measures that the downward pressure received by the support plate 10 is greater than a preset pressure threshold, the electric support assembly can immediately interrupt the supporting force provided for the support plate 10. Without the support of the supporting force of the electric support assembly, the support plate 10 can automatically fall by virtue of its own gravity and the downward pressure exerted on it by the human body, thus realizing the treatment process of falling and pressing suddenly. It can be understood that the falling process of the support plate 10 in this embodiment is not a completely unrestricted fall. In practical applications, a specific limiting structure can be set to limit the falling distance of the support plate 10, so as to ensure the rationality of the falling height of the support plate 10.

[0056] Obviously, the falling process of the support plate 10 in this application is realized by the electric support assembly automatically interrupting its supporting force on the support plate 10. Compared with the current conventional chiropractic pressing bed, in which medical staff apply a certain amount of downward pressure to overcome the resistance of the supporting bed body to fall to realize the process of falling and pressing suddenly, in this embodiment, the requirement for the downward pressure applied by medical staff is lower. That is to say, medical staff can apply a smaller instantaneous downward pressure to realize this process of falling and pressing suddenly, which saves the physical strength of medical staff to a great extent.

[0057] Furthermore, in this embodiment, it is further considered that after the support plate 10 falls, for the next pressing operation, that is, the support plate 10 needs to be raised back to the set height. For this reason, after the support plate 10 falls and delays for a preset time, the electric support assembly can further apply an upward driving force to the support plate 10, so that the support plate 10 can move upward until the support plate 10 rises back to the set height. At this time, the electric support assembly maintains the upward supporting force applied to the support plate 10, and further makes the support plate 10 maintain the position at the set height. Thus, it can be seen that after each completion of the falling and pressing of the support plate 10 in this embodiment, after delaying for a preset time, the process of rising and recovering can be automatically realized by the electric support assembly without manual operation by medical staff or other users, thus simplifying the operation process of chiropractic pressing to a certain extent.

[0058] Based on the above discussion, the electric support assembly in this application specifically has three different working states. The first is to provide an upward supporting force for the support plate 10 so that the support plate 10 can be fixed at the set height; the second is to interrupt and remove the supporting force applied to the support plate 10 so that the support plate 10 automatically falls and presses suddenly; the third is to provide an upward driving force for the support plate 10 after the support plate 10 falls, driving the support plate 10 to rise back to the set height.

[0059] For the set height where the support plate 10 is located, it can be set to be adjustable based on actual needs. Specifically, in actual applications, the electric support component can be connected to the human-computer interaction device, and the user can input appropriate height parameters through the human-computer interaction device, and the electric support component can control the set height of driving the support plate 10 according to the input height parameters.

[0060] To ensure the accuracy of the rising height of the support plate 10, based on the above embodiment, in an alternative embodiment of the present application, the electric pressing device may further include:

[0061] A distance sensor 30 for detecting the height of the support plate 10;

[0062] When the distance sensor 30 measures that the height of the support plate 10 reaches the set height, the electric support component stops driving the support plate 10 to move upward; wherein the size of the set height is adjustable.

[0063] It can be understood that in actual applications, the height data of the support plate 10 detected by the distance sensor 30 can be used as a feedback parameter for the electric support component to drive the support plate 10 to move upward; when the height data measured by the distance sensor 30 does not reach the set height, the electric support component maintains the state of driving the support plate 10 to rise; and once the height data measured by the distance sensor 30 reaches the set height, the electric support component stops driving the support plate 10 to move upward and only provides a supporting force to keep it at the set height.

[0064] Based on the above embodiment, there can be various different embodiments for the electric support component in the electric pressing device of the present application.

[0065] In a specific embodiment of the present application, the electric support component may include:

[0066] A support seat 20, a pressure transmission member 23 and an electric tractor 21 provided on a pressure sensor 40, and a traction rope 22;

[0067] A main support column 11 is provided below the support plate 10; a guide hole is provided on the support seat 20, and the main support column 11 can be movably inserted into the guide hole;

[0068] One end of the traction rope 22 is wound around the electric tractor 21, and the other end passes around the pressure transmission member 23 and the support seat 20 and is fixedly connected; and the height of the pressure transmission member 23 is higher than the height of the bottom end of the main support column 11 and the height of the electric tractor 21; the pressure sensor 40 is provided below the pressure transmission member 23;

[0069] When the support plate 10 is pulled downward by the end of the traction rope 22 under a downward pressure, the traction rope 22 generates a downward pressure on the pressure transmission member 23, and the pressure transmission member 23 squeezes the pressure sensor 40 downward so that the pressure sensor 40 can detect the corresponding pressure data;

[0070] When it is determined according to the pressure data detected by the pressure sensor 40 that the downward pressure borne by the support plate 10 is greater than the preset pressure threshold, the electric tractor 21 releases the traction rope 22 to freely disengage;

[0071] When the duration for which the electric tractor 21 releases the traction rope 22 reaches the preset duration, the electric tractor 21 winds up and contracts the traction rope 22 to control the traction rope 22 to pull the main support column 11 upward.

[0072] Refer to Figure 1 In this embodiment, a support base 20 is provided below the support plate 10. The support base 20 serves both as a structure for carrying and connecting the electric support assembly and the support plate 10, and as a structure for carrying other components of the electric support assembly. Moreover, it can be understood that in actual applications, the support base 20 should be fixedly supported by other support frameworks of the chiropractic press bed, and a plurality of the above support bases 20 should be sequentially provided on the support framework. Each support base 20 is connected with corresponding structural components such as a support plate 10, a main support column 11, and an electric tractor 21, which will not be elaborated in detail in this embodiment.

[0073] In addition, the distance sensor 30 for detecting the rising and falling position heights of the support plate 10 can also be provided on the support base 20.

[0074] Further, a guiding hole penetrating the height of the support base 20 is provided on the support base 20. A main support column 11 is connected below the support plate 10, and the lower part of the main support column 11 is movably inserted into the guiding hole. The fact that the main support column 11 in this embodiment is movably inserted into the guiding hole means that the main support column 11 and the support plate 10 as a whole can move relative to the support base 20 in the vertical direction, that is, the support plate 10 and the main support column 11 as a whole can move up and down relative to the support base 20; and the guiding hole on the support base 20 also serves as a guiding structure for the up and down movement of the main support column 11 to ensure that the support plate 10 and the main support column 11 can only move in the vertical direction.

[0075] In addition, an electric tractor 21, a traction rope 22, and a pressure transmission member 23 are further provided on the support base 20. In this embodiment, the electric tractor 21 is the main device for providing a support force for the support plate 10 and driving the support plate 10 to move upward; while the traction rope 22 and the pressure transmission member 23 are structural components for realizing the force transmission between the support plate 10 and the electric tractor 21.

[0076] Specifically, both the pressure transmission member 23 and the electric tractor 21 can be arranged on the support base 20. On this basis, as Figure 1 shown, a strip-shaped groove 111 is formed on the side wall of the main support column 11, and a fixing piece 112 is arranged at the bottom end of the main support column 11. The free end of the traction rope 22 extends along the strip-shaped groove 111 on the side wall of the main support column 11 to the bottom end of the main support column 11 and is fixedly connected to the fixing piece 112, that is, the free end of the traction rope 22 is fixedly connected to the main support column 11. The other end of the traction rope 22 is wound around the electric tractor 21. When the electric tractor 21 rotates, the traction rope 22 can be tightened. When the electric tractor 21 is powered off, the traction rope 22 can be released and freely loosened from the electric tractor 21. In addition, a pressure transmission member 23 is further arranged between the main support column 11 and the electric tractor 21. The height of the pressure transmission member 23 is higher than that of the electric tractor 21 and the main support column 11. After the free end of the traction rope 22 extends out of the electric tractor 21, it first bypasses the pressure transmission member 23 upward and then extends downward to the bottom end of the main support column 11 and is fixedly connected to the bottom end of the main support column 11. Thus, when the traction rope 22 is tightened and contracted by the electric tractor 21 and the main support column 11, a downward pressure can be applied to the pressure transmission member 23. On this basis, a pressure sensor 40 is further arranged below the pressure transmission member 23, and the pressure transmission member 23 can be directly placed on the upper surface of the pressure sensor 40 (that is, the sensing and detecting surface of the pressure sensor 40) in a non-fixed manner and is completely supported by the pressure sensor 40.

[0077] As Figure 2 shown, in the electric tractor 21, the rotor of the motor is connected to one end of the reducer. When the rotor of the motor rotates, the high-speed rotating power source of the rotor is converted into the low-speed and high-torque output of the reducer, driving the roller to rotate, and the traction rope 22 is wound around the roller, so that the curling and contraction of the traction rope 22 can be realized; when the electromagnetic clutch 4 of the electric tractor 21 is powered on, the brake mechanism is driven to act, so that the roller of the electric tractor 21 is in a braking state; when the electromagnetic clutch of the electric tractor 21 is powered off, the roller is in a free separation state, and the tension end of the traction rope 22 (that is, the end wound around the roller) is in an unloaded state, and the traction rope 22 can quickly fall off and be released from the roller.

[0078] Thus, in actual work, when the electric tractor 21 tightens the traction rope 22, as it contracts the traction rope 22, the length of the traction rope 22 between the bottom end of the electric tractor 21 and the main support column 11 gradually decreases. The main support column 11 and the support plate 10 also rise accordingly as the traction rope 22 contracts until the support plate 10 rises to the set height. Then the electric tractor 21 can stop rotating and keep the length of the traction rope 22 between the main support column 11 and the electric tractor 21 unchanged, thereby keeping the support plate 10 at the set height unchanged.

[0079] When a relatively large downward pressure is generated on the support plate 10 under the pressing action of medical staff, the support plate 10 and the main support column 11 as a whole will inevitably have a downward movement tendency, which can drive a slight downward movement of the free end of the traction rope 22 (i.e., the end fixedly connected to the main support column 11). At this time, the electric tractor 21 remains stationary, which means that the traction rope 22 exerts a downward pressure on the pressure transmission member 23, and the pressure transmission member 23 can then squeeze the pressure sensor 40 downward, so that the pressure sensor 40 can correspondingly detect the suddenly increased pressure data, and this suddenly increased pressure data is proportional to the magnitude of the downward pressure exerted by the medical staff on the support plate 10. Thus, according to the magnitude of the suddenly increased pressure data detected by the pressure sensor 40, it can be determined whether the downward pressure on the support plate 10 is greater than the preset pressure threshold. When the downward pressure on the support plate 10 is greater than the preset pressure threshold, the electric tractor 21 immediately releases the traction rope 22, that is, the electric tractor 21 interrupts the pulling force on the traction rope 22, and then the pulling force of the traction rope 22 on the main support column 11 immediately disappears, and the main support column 11 and the support plate 10 fall synchronously and rapidly, that is, the falling sudden pressure of the support plate 10 is realized.

[0080] When the main support column 11 and the support plate 10 fall synchronously to the lowest point and after a preset time delay, the electric tractor 21 restarts to tighten the traction rope 22. As the traction rope 22 contracts, the main support column 11 can be pulled upward through the traction rope 22, and the support plate 10 also rises accordingly until the support plate 10 rises to the set height.

[0081] Based on the above discussion, the electric tractor 21 in this embodiment only needs to control the tightening and release of the traction rope 22 to realize the up and down movement of the main support column 11 and the support plate 10 as a whole, as well as the control adjustment to keep the support plate 10 at the set height unchanged, and the structure is simple and easy to implement.

[0082] In an alternative embodiment of the present embodiment, the towing rope 22 can be a flexible towing steel rope to ensure its toughness. In addition, for the pressure sensor 40 provided below the pressure transmission member 23 in the present embodiment, a diaphragm pressure sensor 40 can also be used. Thus, when the medical staff manually presses down the support plate 10, the pressure transmission member 23 can generate an instantaneous small displacement in the vertical direction along with the towing rope 22, and further accurately measure the force exerted by the pressure transmission member 23 on the pressure sensor 40.

[0083] In addition, in an alternative implementation manner of the present embodiment, the pressure transmission member 23 includes a U-shaped groove block 232 and a pulley 231 disposed in the U-shaped groove block 232; both ends of the pulley 231 are connected to the two groove walls of the U-shaped groove block 232 by bearings;

[0084] The towing rope 22 is arranged to bypass the pulley 231; the pressure sensor 40 is disposed at the bottom of the U-shaped groove block 232.

[0085] As Figure 1 shown, in the present embodiment, the U-shaped groove block 232 and the pulley 231 together form the pressure transmission member 23. Among them, the pulley 231 is a structure for carrying the winding of the towing rope 22, so as to minimize the frictional resistance between the towing rope 22 and the pulley 231 during the release and contraction processes.

[0086] The U-shaped groove block 232 is used to support the pulley 231 on the one hand, and on the other hand, it is used to transmit the downward pressure exerted by the towing rope 22 on the pulley 231 to the pressure sensor 40.

[0087] In addition, as Figure 1 shown, in order to be able to install and set the U-shaped groove block 232 and the pulley 231, a groove for accommodating the U-shaped groove block 232 can be opened on the support base 20, the pressure sensor 40 can be disposed at the bottom of the groove, and the U-shaped groove block 232 can be disposed in the groove and pressed on the pressure sensor 40.

[0088] In addition, in order to prevent the U-shaped groove block 232 from shifting horizontally when the towing rope 22 exerts a downward pressure on the pulley 231, in another alternative embodiment of the present embodiment, a limiting structure connected to the U-shaped groove block 232 is further provided on the support base 20 to limit the horizontal movement of the U-shaped groove block 232.

[0089] Specifically, vertical card slots can be provided on the two side walls of the groove on the support base 20 that accommodates the U-shaped groove block 232, so that the two sides of the U-shaped groove block 232 can be snapped into the vertical card slots. Moreover, the height dimension of the vertical card slot in the vertical direction is greater than the height of the U-shaped groove block 232, while the width of the vertical card slot in the horizontal direction is basically the same as the dimension of the U-shaped groove block 232 in the horizontal direction. Thus, when the two sides of the U-shaped groove block 232 can be inserted into the vertical card slots, the movement of the U-shaped groove block 232 in the horizontal direction can be restricted, but its movement in the vertical direction is not affected. That is to say, in the vertical direction, except for the traction rope 22 and the pressure sensor 40, the U-shaped groove block 232 is no longer subjected to the acting force exerted by other structural components. That is, it can better transmit the downward pressure received by the support plate 10 to the pressure sensor 40 through the main support column 11, the traction rope 22, the pulley 231, and the U-shaped groove block 232 in sequence, that is, to realize the indirect detection of the downward pressure received by the support plate 10 by the pressure sensor 40.

[0090] As described above, the main support column 11 below the support plate 10 is inserted into the guiding hole of the support base 20, which can play a guiding role in the up and down movement of the support plate 10. In another optional embodiment of the present embodiment, the support base 20 is further provided with

[0091] At least two side support columns 12 are further provided below the support plate 10;

[0092] Side guiding holes are further provided on the support base 20; the bottom ends of the side support columns 12 can be movably inserted into the side guiding holes; and a spring member 13 is further sleeved on the side support columns 12, and the spring member 13 is located between the support base 20 and the support plate 10.

[0093] As Figure 1 shown, in Figure 1 the embodiment shown, a main support column 11 and two side support columns 12 are provided below the support plate 10; and the main support column 11 and the two side support columns 12 are parallel to each other. And the guiding hole and the two side guiding holes on the support base 20 are also parallel to each other. Thus, the support plate 10 and the support base 20 can be movably connected to each other through three columnar structures, which can ensure the stability of the lifting movement of the support plate 10 relative to the support base 20 to a certain extent.

[0094] In addition, a spring member 13 located between the support base 20 and the support plate 10 is further provided on the side support column 12. When the support plate 10 quickly falls and presses to the lowest point, on the one hand, the spring member 13 can control the falling height of the support plate 10, and on the other hand, it can also appropriately buffer the impact force generated by the falling of the support plate 10 on the support base 20.

[0095] In summary, a pressure sensor capable of detecting the downward pressure on the support plate is provided below the support plate in this application. Thus, this pressure sensor is used to sense and detect the action of a medical staff manually pressing down. An electric support assembly is also provided to provide an upward support force for the support plate. When the downward pressure borne by the support plate measured by this pressure sensor is greater than a preset pressure threshold, the electric support assembly can immediately withdraw its support force on the support plate, enabling the support plate to quickly fall instantaneously, thereby realizing the impact treatment on the body on the support plate. It can be seen that the downward impact of the support plate in this application is achieved by the electric support assembly withdrawing the support force, and it is not necessary for the medical staff to apply too much downward pressure. Thus, to a certain extent, the physical strength of the medical staff is saved. In addition, after the support plate completes the downward impact in this application, the electric support assembly can also automatically drive the support plate to rise, eliminating the need for the patient or medical staff to perform the operation of raising the support plate, that is, simplifying the operation process of the device.

[0096] This application also provides an embodiment of a control method for an electric impact device. This control method is applied to the electric impact device described in any one of the above, as Figure 3 and Figure 4 shown,

[0097] Figure 3 is a schematic framework diagram of the control system of the electric impact device provided by the embodiment of this application;

[0098] Figure 4 is a schematic flow diagram of the control method of the electric impact device provided by the embodiment of this application.

[0099] In a specific embodiment of this application, the control method of the electric impact device may include:

[0100] S1: Real-time collect the pressure data of the support plate collected by the pressure sensor in the electric impact device;

[0101] S2: Judge whether the downward pressure borne by the support plate is greater than a preset pressure threshold according to the pressure data. If so, enter S3; if not, enter S1.

[0102] S3: Control the electric support assembly in the electric impact device to interrupt providing an upward support force for the support plate;

[0103] S4: When the duration for which the electric support assembly interrupts providing an upward support force for the support plate reaches a preset duration, control the electric support assembly to drive the support plate to move upward to a set height.

[0104] Refer to Figure 3 and Figure 4, in practical applications, a dedicated MCU controller can be configured in the electric pressing device. The MCU controller can be respectively connected to a pressure sensor, a distance sensor, and an electric support component. Thus, during the actual treatment of a patient, after the patient lies on the support plate, the pressure sensor detects the pressure data representing the downward pressure on the support plate and transmits the pressure data to the MCU controller. The MCU controller determines whether the downward pressure borne by the support plate is greater than a preset pressure threshold based on the pressure data uploaded by the pressure sensor; once it is determined that the downward pressure borne by the support plate is greater than the preset pressure threshold, the MCU controller can control the electric support component to immediately interrupt the upward support force provided to the support plate, so that the support plate can automatically fall without relying on the downward pressure of medical staff to drive its fall.

[0105] On this basis, after a preset time delay after the support plate falls, the MCU controller can control the electric support component to automatically drive the support plate to rise to a position at a set height and support the support plate to remain at the set height position until the medical staff applies a downward pressure to the support plate next time.

[0106] In addition, the MCU controller in this embodiment can further be connected to a human-machine interaction device, and the user can set and input a suitable set height through the human-machine interaction.

[0107] In addition, the preset pressure threshold in this embodiment is a pressure threshold greater than the downward pressure determined based on the downward pressure exerted by the human body on the support plate when the patient lies on the support plate.

[0108] Further, in order to more accurately determine whether the downward pressure borne by the support plate is greater than the preset pressure threshold, in an optional implementation manner of this embodiment, the above step S2 may specifically include:

[0109] S21: Perform an average filtering operation on each pressure data within the sliding window containing the current pressure data by using a moving average filtering algorithm to obtain a filtered pressure value.

[0110] S22: Determine whether the filtered pressure value is greater than the preset pressure threshold. If so, the downward pressure borne by the support plate is greater than the preset pressure threshold.

[0111] In this embodiment, the moving average filtering algorithm is used to perform arithmetic processing on the pressure data real-time collected by the pressure sensor, which can effectively reduce the noise in the pressure data or remove the high-frequency components, thereby smoothing the signal.

[0112] Specifically, a sliding window with a certain window length can be set, and multiple pressure data falling within the sliding window are selected from the pressure data sequence measured by the pressure sensor; and an average value filtering operation is performed on the pressure data falling within the sliding window. The filtered output y[k] can be calculated by the following formula:

[0113]

[0114] The filtered output y[k] is used as the filtered pressure value corresponding to the pressure data x[k]. When actually judging whether the downward pressure borne by the support plate is greater than the preset pressure threshold, it is directly judged whether the filtered pressure value y[k] is greater than the preset pressure threshold; where 1 / M is the normalization factor.

[0115] In practical applications, x[k] is generally the pressure data collected by the pressure sensor at the current moment. That is to say, in this embodiment, the average value filtering operation is jointly performed using x[k] and the previous M - 1 pressure data, and then the filtered pressure value after the average value filtering operation of the pressure data at the current moment is determined, and this is compared with the preset pressure threshold. If the filtered pressure value is not greater than the preset pressure threshold, the current pressure data newly collected by the pressure sensor is obtained again, and at the same time, the sliding window is slid backward by one sampling time point (i.e., the time series of the time intervals between adjacent two pressure data acquisitions), and the filtered pressure value corresponding to the new current pressure data is determined in the above manner.

[0116] Furthermore, considering that in this embodiment, the window length of the sliding window for selecting pressure data determines the degree of smoothing. A larger window length can more effectively smooth the signal, but may cause a lag in the control response of the electric support assembly; while a smaller window length can respond more quickly to signal changes, but the smoothing effect may be poor. Therefore, in this embodiment, a dynamic window length can be further adopted to perform a moving average filtering operation on the pressure data.

[0117] In a specific implementation manner of this embodiment, before the above step S21, it may further include:

[0118] S210: Perform an absolute value operation on the difference between the current pressure data and the pressure data measured at the previous adjacent moment to obtain the absolute value of the pressure difference;

[0119] S211: If the absolute value of the pressure difference is greater than the preset deviation value, set the size of the sliding window to the first window length; where the preset deviation value is one-tenth of the difference between the preset pressure threshold and the body weight pressure;

[0120] S212: If the absolute value of the pressure difference is not greater than the preset deviation value, determine whether the number of pressure data belonging to the pressure data in the steady shock region of the jerky pressure is greater than the second window length. If so, use the second window length as the size of the sliding window. If not, use the number of data as the size of the sliding window;

[0121] Among them, the pressure data belonging to the steady shock region of the jerky pressure is the pressure data including the current pressure data and multiple continuously collected pressure data collected before the current pressure data, and the absolute value of the pressure difference corresponding to each pressure data belonging to the steady shock region of the jerky pressure is not greater than the preset deviation value; the first window length is less than the second window length.

[0122] In this embodiment, the gravity of the jerky pressure part of the patient's body can be accurately calculated first. For example, after the patient lies on the support plate and before the medical staff performs the pressing operation, multiple groups of pressure data are collected by the pressure sensor, and the average value of the pressure data is calculated. This average value can be used as the body weight pressure representing the gravity of the jerky pressure part of the patient.

[0123] When performing jerky pressure treatment on the patient, since the jerky pressure therapy is that the medical staff instantaneously presses a part of the body, causing the pressure sensor to generate a rapidly responsive trapezoidal signal; selecting the pressure data by a sliding window with a fixed window length and performing moving average filtering will cause the filtered pressure data to be distorted and calculate an incorrect filtered pressure value.

[0124] Therefore, in this embodiment, a sliding window with a variable window length is used to calculate the filtered pressure value by the moving average filtering method, and the size of the sliding window can be determined based on the preset deviation value, where the preset deviation value = (preset pressure threshold - body weight pressure) / 10.

[0125] If the current pressure data minus the pressure data collected at the previous moment is greater than the preset deviation value, then the current jerky pressure is the rising edge of the trapezoidal signal, and the window length of the sliding window is reduced to the first window length;

[0126] If the pressure data collected at the previous moment minus the current pressure data is greater than the preset deviation value, then the current jerky pressure is the falling edge of the trapezoidal signal, and the window length of the sliding window is reduced to the first window length;

[0127] If the difference between the current pressure data and the pressure data collected at the previous moment does not meet any of the above two situations, that is, the magnitude of the difference between the current pressure data and the pressure data collected at the previous moment is less than the preset deviation value, it means that the current pressure data is located in the middle region between the rising and falling edges of the trapezoid. The pressure data located in this middle region is also the pressure data belonging to the steady shock region of the jerky pressure;

[0128] If the number of pressure data belonging to the steady shock region of the dwell pressure is greater than the second window length, the second window length is used as the window length of the sliding window for moving average filtering operation.

[0129] If the number of pressure data belonging to the steady shock region of the dwell pressure is not greater than the second window length, the length of the steady shock region is used as the window length of the sliding window for moving average filtering operation.

[0130] In this embodiment, the size of the sliding window is flexibly adjusted according to different situations of the current pressure data, so as to ensure the smoothing effect of the filtered pressure data while being able to respond more quickly to the change of the pressure data signal.
