Description

Technical Field

[0001] The invention relates to medical equipment, in particular to an intelligent pulse-controlled voice coil motor, which is mainly suitable for a pulse diagnosis instrument reproduction end without a hydraulic component. Background Art

[0002] Pulse diagnosis is one of the important methods of traditional Chinese medicine for diagnosing diseases. It has a long history and a profound theoretical basis. Chinese medicine practitioners touch the pulse of the patient's wrist with their fingers to perceive various characteristics of the pulse, such as pulse position, pulse rate, pulse strength, pulse shape, etc., so as to judge the health status of the human body and the nature, location and degree of the disease, providing key basis for syndrome differentiation and treatment. However, this traditional pulse diagnosis method faces many limitations and challenges in modern society.

[0003] As people's pace of life accelerates and geographical scope expands, patients may not be able to go to hospitals or clinics in time to receive on-site pulse diagnosis by TCM practitioners due to factors such as distance, time, and physical inconvenience. For example, patients in remote areas may lack local high-quality TCM medical resources and need to travel long distances to obtain professional pulse diagnosis services; some patients with chronic diseases or mobility impairments have great difficulties in frequently going out for medical treatment; in addition, in special circumstances such as global public health events, people's travel is restricted and on-site medical treatment is hindered, which makes it difficult to implement traditional face-to-face pulse diagnosis, seriously affecting the timeliness and convenience of TCM diagnosis and treatment, which may delay the diagnosis and treatment of the disease and pose a potential threat to the health of patients.

[0004] In order to solve these problems, the field of science and technology has been constantly exploring the possibility of using modern technology to achieve remote pulse diagnosis in recent years. Some early attempts included patients describing the feeling of the pulse or using simple pulse monitoring equipment to record pulse data and transmit it to doctors, but these methods have obvious limitations. Patients' self-description of pulses is often inaccurate and subjective, and it is difficult to truly reflect the subtle characteristics and changes of the pulse; and ordinary pulse monitoring equipment can usually only obtain limited information such as basic pulse frequency, and cannot comprehensively and accurately collect the rich information contained in the pulse, such as the changes in the strength of the pulse, elastic characteristics, the thickness of the blood vessels, and the smoothness of blood flow. Complex and critical indicators make it difficult for doctors to make accurate and reliable TCM diagnosis conclusions based on these incomplete data.

[0005] In order to simulate the blood flow and vascular elasticity of the human wrist, the existing cloud pulse instrument reproduction end often has the following necessary features: On the one hand, in order to simulate the elasticity of blood vessels, it is necessary to use a closed or open liquid circulation cavity and a liquid container with high elasticity (such as a hydraulic oil tank) to simulate the pumping out and pumping in of blood by the heart. The circulation system must use a circulation cavity with pressure. On the other hand, in order to simulate real blood, it is also necessary to use a liquid with similar density and add specific electrolytes to it to ensure viscosity and density. Due to the adoption of the above necessary features, the following problems are bound to arise: as the closed liquid circulation cavity continues to expand and contract, the aging of the material will be accompanied by pressure changes, that is, the same elastic force is generated at the end of the capillary, and a greater internal pressure needs to be applied at the container end, which leads to the final reproduction effect gradually distorted, and the pressure applied by the voice coil motor needs to be increased regularly to compensate for the error caused by material aging. But at the same time, the elasticity of the circulation cavity does not decay linearly. When adjusting the pressure to compensate for the error, experienced Chinese medicine practitioners need to intervene to ensure that the input signal is as consistent as possible with the actual reproduction result. As a result, a lot of repetitive work has been caused, which wastes manpower and resources and is inconvenient to use. The hydraulic storage box increases the overall size and weight of the equipment, which is not conducive to miniaturization and portable use.

[0006] In addition, since an open piping system is used, the sealing of each pipe joint must be considered. Since the pipes are usually thin, when the material aging characteristics decay, or when the pipeline undergoes fatigue swing driven by diastolic and systolic pressure, it will also be accompanied by leakage or even breakage of the inner wall or pipe joints, resulting in a gradual increase in the maintenance frequency and increased use costs. Furthermore, the indirect transmission of pressure fluctuations through the liquid in the elastic liquid circulation cavity is bound to cause delays, resulting in poor physical sensations at the beginning of reproduction. Summary of the invention

[0007] The purpose of the present invention is to provide an intelligent pulse voice coil motor, which fundamentally solves the above problems and has the advantages of simple structure, accurate reproduction, and easy use.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the intelligent control pulse voice coil motor comprises a motor bracket, a first voice coil motor and a second voice coil motor fixed on the motor bracket, and the technical key points are: the motor bracket comprises an L-shaped bottom bracket and an inverted L-shaped support frame that cooperate with each other, and an L-shaped top bracket fixed on the support frame, the vertical parts of the bottom bracket and the top bracket are respectively located on two vertical planes that do not interfere with each other, the bottom bracket is provided with a first motor limit groove, and the top bracket is provided with a second motor limit groove; A hollow first conduit positioning column is provided on the bottom bracket, and a first conduit positioning cap is fixed on the first conduit positioning column; A hollow second conduit positioning column is provided on the top bracket, and a second conduit positioning cap is fixed on the second conduit positioning column; The first voice coil motor includes a motor body embedded in a first motor limiting groove, a pair of first guide shafts fixed in the bottom bracket along the vertical direction, a first motor cover floatingly arranged along the first guide shaft and constrained by the bottom bracket, a first fiber clamping groove matched with a first guide tube positioning column is provided at the rear end of the first motor cover, and a first locking card is fixed on the first fiber clamping groove; The second voice coil motor includes a motor body embedded in a second motor limiting groove, a pair of second guide shafts fixed in the top bracket along the vertical direction, a second motor cover with propyne floatingly arranged along the second guide shaft and restricted by the top bracket, a second fiber clamping groove matched with the second guide tube positioning column is provided at the rear end of the second motor cover, and a second locking card is fixed on the second fiber clamping groove; Furthermore, a plurality of bottom mounting cards are provided at the bottom of the bottom bracket.

[0009] Beneficial effects of the present invention: Due to its simple structure, small size, fast response, and non-hysteresis response, the output end of the voice coil motor unit directly drives the floating of each point in the flexible pad through the conductive fiber in a manner with almost zero delay. Without relying on liquid conduction, high-precision multi-point feedback reproduction can still be achieved, avoiding the risk of misdiagnosis caused by delay at the reproduction end.

[0010] The reproduction end still uses a fingerprint unit with multi-point feedback reproduction, eliminating the liquid container. Without affecting the reproduction accuracy, the structure of the existing reproduction device is simplified, making the overall design simple and completely avoiding the risk of leakage caused by material aging and pipe joint sealing. The simplified structure reduces the number of failure points and the probability of overall equipment failure due to component failure, greatly improving the stability and reliability of the equipment. There is no need to frequently check and maintain the liquid system, reducing maintenance costs and manpower investment, while reducing equipment failures and damages that may be caused by leakage, and extending the service life of the equipment.

[0011] The control module of the present invention can quickly and accurately convert the pulse signals of the Cun, Guan and Chi parts into floating current, and finally convert it into the movement of the guiding fiber through the voice coil motor, accurately reproducing various characteristics of the pulse wave on the flexible pad of the fingerprint unit in a dot array manner, meeting the requirements of different users and application scenarios for the accuracy of pulse wave reproduction, and improving the overall performance and applicability of the pulse diagnosis instrument.

[0012] The motor bracket adopts a modular structure, and a plurality of L-shaped brackets are stacked in the height direction, and the guide fibers are led out at the rear end of the motor bracket. The misaligned structure at the rear end of the bracket avoids interference between the guide fibers.

[0013] In summary, the cloud pulse instrument reproduction end of the present invention simplifies the structure and avoids the risk of leakage, while improving stability and reliability. It is easy to operate, convenient for data transmission, and more accurate in reproducing pressure signals, providing a more advanced and reliable device for traditional Chinese medicine pulse diagnosis.

[0023] The following combination Figures 1 to 5 , the specific contents of the present invention are described in detail through specific embodiments.

[0024] Embodiment 1 Voice coil motor unit 3

[0025] like Figures 2~5As shown, the intelligent control pulse voice coil motor includes a motor bracket 34, a first voice coil motor 31 and a second voice coil motor 32 fixed on the motor bracket 34. The motor bracket 34 includes an L-shaped bottom bracket 341 and an inverted L-shaped support frame 343 that cooperate with each other, and an L-shaped top bracket 342 fixed on the support frame 343. The vertical parts of the bottom bracket 341 and the top bracket 342 are respectively located on two vertical planes that do not interfere with each other. The bottom bracket 341 is provided with a first motor limit groove 3413, and the top bracket 342 is provided with a second motor limit groove 3423.

[0026] The bottom bracket 341 is provided with a hollow first conduit positioning column 3411, and a first conduit positioning cap 3412 is fixed to the first conduit positioning column 3411. The top bracket 342 is provided with a hollow second conduit positioning column 3421, and a second conduit positioning cap 3422 is fixed to the second conduit positioning column 3421.

[0027] The first voice coil motor 31 includes a motor body embedded in a first motor limiting groove 3413, a pair of first guide shafts 313 fixed in the bottom bracket 341 along the vertical direction, a first motor cover 311 floatingly arranged along the first guide shaft 313 and constrained by the bottom bracket 341, and a first fiber clamping groove 312 matched with the first guide tube positioning column 3411 is provided at the rear end of the first motor cover 311, and a first locking card 314 is fixed on the first fiber clamping groove 312. A plurality of bottom mounting cards 3415 are provided at the bottom of the bottom bracket 341.

[0028] The second voice coil motor 32 includes a motor body embedded in a second motor limit groove 3423, a pair of second guide shafts 323 fixed in the top bracket 342 along the vertical direction, and a second motor cover 321 floatingly arranged along the second guide shafts 323 and constrained by the top bracket 342. The rear end of the second motor cover 321 is provided with a second fiber clamping groove 322 that cooperates with the second guide tube positioning column 3421, and a second locking card 324 is fixed on the second fiber clamping groove 322.

[0029] In order to identify the action of the first motor cover 311 or the first fiber slot 312, a Hall signal plate (not shown in the figure) is also provided on the bottom bracket 341 or the top bracket 342, and a magnet (not shown in the figure) is provided on one side of the Hall signal plate and the first motor cover 311 or the second motor cover 321. In order to facilitate the connection of the drive circuit, a motor drive plate (not shown in the figure) is fixed to the side of the bottom bracket 341 and the top bracket 342.

[0030] This embodiment is described by taking the bottom bracket 341 and the top bracket 342 of the two-layer L-shaped bracket as an example. In actual application, it can be set according to the weight and size of the voice coil motor, the internal layout of the box assembly 1, etc. However, it should be noted that for the purpose of portability, the bracket is usually lightened, and the bottom bracket may resonate between the voice coil motors, resulting in an increase in the swing amplitude of the top bracket, which reduces the stability of the overall structure. Therefore, it is preferred to use a two- to three-layer bracket. The specification takes a two-layer bracket as an example to illustrate the specific implementation scheme of the present invention.

[0031] Embodiment 2 Fingerprint unit 2

[0032] like Figure 1c , Figure 1d As shown, this embodiment mainly describes a finger mold unit 2 used in conjunction with the voice coil motor unit 3 in Embodiment 1, which specifically includes a finger mold body 21 provided with a groove 213, an upper cover 23 embedded in the groove 213, and a flexible pad 22 covering the upper cover 23. A hollow embedded protrusion 212 for conducting fibers is provided at the bottom of the finger mold body 21, a guide column 211 is provided in the groove 213, and the hollow structure of the groove 213 and the embedded protrusion 212 is connected through the guide column 211. A clustering end 231 with array through holes is provided in the middle of the upper cover 23, and the number of array through holes corresponds to the number of guiding fibers in the guide column 211. In order to facilitate the installation of the finger mold unit 2, the finger mold body 21 is set to a symmetrical stepped structure for easy embedding. During installation, after the finger mold unit 2 is assembled, it is embedded in the upper half of the sheet metal frame 14 from bottom to top, and then the screws on both sides of the finger mold body 21 are tightened to fix it one by one on the sheet metal frame 14.

[0033] When in use, the voice coil motor unit 3 drives its corresponding guide fiber to move in the plastic conduit. When the motor cover floats upward, the guide fiber protrudes upward outside the cluster end 231 and presses the inner wall of the flexible pad 22; when the motor cover floats downward, the guide fiber moves downward, causing the corresponding point position on the array point of the cluster end 231 to be concave. Thus, through the synergistic effect of multiple points, each guide fiber floats up and down regularly along the guide column 211 as time flows, realizing the pixel-level reproduction of the Cun, Guan, and Chi acupoints.

[0034] This embodiment is described by taking the guide column 211 with ten points as an example. If the manufacturing cost is not considered, the voice coil motor can be further miniaturized, the number of voice coil motors can be increased, and the number of layers of motor brackets 34 can be increased. In this way, the "resolution" of the reproduction can be increased without significantly increasing the overall weight of the device.

[0035] Example 3 Cloud Pulse Instrument Reproduction Terminal

[0036] like Figure 1 , Figure 1a , Figure 1bAs shown, this embodiment mainly describes the cloud pulse instrument reproduction end using the voice coil motor unit 3 in embodiment 1, which specifically includes a box assembly 1, three finger mold units 2 arranged side by side, and a plurality of voice coil motor units 3 for driving the finger mold units 2. Among them, the box assembly 1 includes a main shell 12 with an open front end, an L-shaped front shell 11 snap-fitted to the front end opening of the main shell 12, and a sheet metal frame 14 fixed in the front shell 11.

[0037] The sheet metal frame 14 adopts a frame structure consisting of an upper and lower part. The middle of the frame of the lower half is fixed to the bottom surface of the main shell 12 and the two sides are symmetrically raised. The frame of the upper half is n-shaped, and its two sides are welded to the two sides of the lower half or fixed by bolts and nuts. The finger mold unit 2 is fixed to the middle of the frame of the upper half, and a number of voice coil motor units 3 are symmetrically distributed and fixed on the lower half of the sheet metal frame 14. After the front shell 11 is buckled with the main shell 12, the finger mold frame 112 is clamped and fixed to the middle of the front shell 11. A detachable back plate is set on the back of the main shell 12, and the exhaust port of the exhaust fan is installed on the back plate. Further, for easy operation, a power switch 111 is set on one side of the front shell 11. In order to facilitate human-computer interaction or remote visual communication, a display screen assembly 13 is hinged on the main shell 12, and an audio module and a microphone module are set on the main shell 12. For ease of use, a pair of magnets are symmetrically arranged on the front housing 11, and the display screen assembly 13 can be magnetically attracted to the front housing 11 when it is buckled. For ease of carrying the device, buckles (not marked in the figure) are also arranged on both sides of the main housing 12. For an aesthetically pleasing appearance, a light strip (not marked in the figure) is arranged at the front of the front housing 11.

[0038] During assembly, each voice coil motor unit 3 is fixed to the lower half of the frame of the sheet metal frame 14 in a symmetrical manner through the bottom mounting clips 3415 according to the preset layout. Since the two sides of the bottom frame rise symmetrically, each motor bracket 34 is limited by the bottom mounting clips 3415 under the action of its own weight, and the assembly can be completed without using a bolt assembly. After the voice coil motor unit 3 is installed, the power line and the drive data line of the driving board (not shown in the figure) of each voice coil motor unit 3 are electrically connected to the hub (not shown in the figure) fixed on the inner wall of the front end or rear end of the main housing 12 through the lead wire with a quick plug interface.

[0039] Since there are many repetition points and each point corresponds to a voice coil motor, a multi-layered motor bracket 34 is used to facilitate the assembly of the voice coil motor array. This embodiment is described by taking a double-layer bracket as an example. The motor bracket 34 includes a bottom bracket 341 fixed to the sheet metal frame 14, a support frame 343 fixed to the bottom bracket 341, and a top bracket 342 fixed to the support frame 343.

[0040] like Figure 3 , Figure 4 , Figure 5 As shown, the installation method of the conductive fiber (not marked in the figure) and the plastic conduit (not marked in the figure) is described below by taking the first voice coil motor 31 as an example. The bottom of the first voice coil motor 31 is embedded in the first motor limit groove 3413 of the bottom bracket 341 and is fastened by bolts from bottom to top. The bottom bracket 341 is symmetrically fixed with a pair of first guide shafts 313 on both sides of the first motor limit groove 3413. The first motor cover 311 is fixed to the linear moving component (not marked in the figure) by a pair of bolts and guided by the first guide shaft 313. It can float with the moving component and fit on the first voice coil motor 31. The first voice coil motor 31 is provided with a first fiber clamping groove 312 at the rear end, and a first locking card 314 is fixed to the first fiber clamping groove 312 by a pair of bolts. A hollow first conduit positioning column 3411 is coaxially provided on the bottom bracket 341 with the corresponding part of the first fiber clamping groove 312, and a first conduit positioning cap 3412 is fastened to the first conduit positioning column 3411.

[0041] The bottom end of the conductive fiber (not marked in the figure) is embedded in the first fiber card slot 312 and fastened by the first locking card 314, so that the conductive fiber can float with the first motor cover 311. The bottom end of the plastic conduit (not marked in the figure) is embedded in the first conduit positioning groove 3414 or the second conduit positioning groove 3424 and fastened by the first conduit positioning cap 3412. The other end of the conductive fiber penetrates into the plastic conduit and continues to extend upward. The plastic conduit and the guide fiber extend upward to the guide column 211 of one of the finger mold bodies 21 synchronously. Among them, the conductive fiber in the conduit has a certain bending resistance, so that the conductive fiber protruding outside the guide column 211 avoids bending and affects the accuracy of the reproduction result; at the same time, it should also have a certain toughness to avoid the middle section between the guide column 211 and the voice coil motor from breaking during the floating process of the first motor cover 311 or the second motor cover 321. Therefore, polyetheretherketone (PEEK), polycarbonate (PC), quartz or glass fiber, etc. are preferably used. Furthermore, the outer diameter of the guide fiber is slightly smaller than the inner diameter of the plastic conduit, so as to reduce the resistance of the guide fiber during sliding as much as possible.

[0042] In order to avoid mutual interference between the guide fibers at the output ends of the two sets of voice coil motors, the bottom bracket 341 and the top bracket 342 are designed to be a front-to-back offset structure. In order to improve the guiding and sliding effects, a sufficiently long vertical section is reserved at the initial guiding end (i.e., the first fiber clamping groove 312 and the first guide tube positioning column 3411) and the terminal section (i.e., the guide column 211). In order to avoid excessive floating of the first motor cover 311 or the second motor cover 321, the bottom bracket 341 and the top bracket 342 both adopt a gantry structure, which, on the one hand, facilitates the backward retraction of the voice coil motor and reduces the overall thickness of the motor bracket 34, and on the other hand, can also limit the stroke of the first motor cover 311 or the second motor cover 321.

[0043] In order to more intuitively illustrate the main structure of the present invention, most of the wires, bolts, nuts, sealing rings and other parts are omitted in the accompanying drawings. It can be understood that under the conception of the present invention, technical personnel in this field can connect and fix the corresponding parts in practical applications in combination with conventional technical means in the field, and flexibly adjust and optimize according to actual conditions to implement the technical solution of the present invention.
