Description

A new type of hollow loading integrated platform at the end of a physiotherapy manipulator

[0001] This application claims the benefit of Chinese patent application No. 2024206484248, filed on April 1, 2024. This application incorporates the entirety of the aforementioned Chinese patent application. Technical Field

[0002] The utility model belongs to the technical field of human body services, in particular to a novel hollow loading integrated platform at the end of a physiotherapy manipulator. Background Art

[0003] When existing physiotherapy robots are performing massage or shock wave therapy, their human contact force detection mostly only detects the magnitude of a one-dimensional upward force and cannot sense the tilt of the force. In other words, they cannot sense and detect the force posture of the end of the robot in contact with the human body, and cannot provide more comprehensive physiotherapy services. If a multi-dimensional force sensor solution is used, the cost will be very high. When existing massage therapy robots come into contact with the human body, if an abnormal state occurs, such as continuously pressing down on the human body, it will cause harm to the human body, or if the robot stops pressing on the human body, it will be difficult for the human body to move away, posing a safety risk. At the same time, physiotherapy equipment such as shock wave therapy devices and life meridian devices are generally installed by fastening screws on the mounting frame, which is difficult to quickly disassemble and replace, and inconvenient to maintain.

[0004] Therefore, a new type of hollow loading integrated platform at the end of the physiotherapy manipulator is needed. This platform can quickly disassemble and replace the intermediate physiotherapy equipment, can detect the tilt state of the force at a low cost, and has a pure mechanical protection function that can automatically pop open when the force in contact with the human body is greater than the set value.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0065] Example 1

[0066] 1-17, a novel hollow loading integrated platform at the end of a physiotherapy manipulator in this embodiment comprises:

[0067] An overload release protection assembly 2000, comprising an overload release sleeve 2100 and a mounting base 2200 that are movably connected. A safety assembly 2300 that provides a pre-contact force for overload protection is provided on the inner and outer sliding contact surfaces of the overload release sleeve 2100 and the mounting base 2200.

[0068] The mounting bracket 5000 is provided with an interface for connecting to the corresponding controllable operation platform; the quick-release component 3000 is used to connect the physical therapy component 1000, and the quick-release component 3000, the over-force elastic release protection component 2000 and the hollow area of ​​the mounting bracket 5000 are interconnected and clamp and fix the physical therapy component 1000.

[0069] The force sensing assembly 4000 includes a force sensor 4100, which is disposed between the mounting base 2200 and the mounting bracket 5000. The platform of this embodiment, by providing the force sensing assembly 4000, can accurately detect the magnitude of the generated contact force. Furthermore, the over-force release protection assembly 2000 can disengage the over-force release sleeve 2100 from the mounting base 2200 when the contact force is excessive, providing overload protection and significantly improving overall safety.

[0070] There are three or more force sensing components 4000, and the lower ends of the force sensing components 4000 are evenly distributed and installed along the circumference on the mounting bracket, and the upper ends of the force sensors are finally connected to the physical therapy device 1000 through the intermediate components. When the force at the contact point between the physical therapy device 1000 and the human body is tilted in direction, the different force values ​​of each sensor force sensor 4100 can be used to calculate the force tilt angle. When the force at the contact point between the end of the physical therapy device 1000 and the human body is in an inclined state, the axial tensile and pressure forces generated on each force sensing component 4000 are different, so that the approximate force tilt direction can be judged by the different forces detected by multiple groups of force sensing components 4000, and the posture of the manipulator can be adjusted so that the force detected on each group of force sensors tends to be the same, so that the posture of the end force can be measured and controlled, and the resultant force can determine the size of the contact force to better provide physical therapy services to the human body.

[0071] Moreover, the present application can achieve accurate measurement of the direction of the contact surface by adopting a simple force sensor 4100, which greatly saves costs.

[0072] The force sensing components 4000 are evenly distributed along the force-bearing areas of the contact surface. When force tilt occurs in any direction, it can be accurately detected by the corresponding force sensing component 4000, thereby improving the comprehensiveness of the detection.

[0073] The measurement direction of the force sensor 4100 is consistent with the relative small movement direction of the mounting base 2200 and the mounting bracket 5000. The relative small movement of the mounting base 2200 and the mounting bracket 5000 causes the force sensor 4100 and the mounting bracket 5000 to pull and press and measure.

[0074] The force sensing assembly 4000 includes a force sensor 4100 and a movable connecting piece mounted on the outside of the force sensor 4100. The two ends of the movable connecting piece are respectively connected to the mounting base 2200 and the mounting bracket 5000. The movable direction of the movable connecting piece is consistent with the measurement direction of the force sensor 4100 and the relative small movement direction of the mounting base 2200 and the mounting bracket 5000. The relative small movement of the mounting base 2200 and the mounting bracket 5000 drives the force sensor 4100 and the mounting bracket 5000 in the movable connecting piece to pull and press and measure.

[0075] The movable connecting part includes a sensor guide sleeve 4200 and a sensor guide shaft 4300 arranged in the sensor guide sleeve 4200. The sensor guide shaft 4300 includes a cylindrical connecting part 1 4320 and a cylindrical connecting part 2 4330 connected to each other. The cylindrical connecting part 1 4320 is provided with an internal threaded hole 4310 at one end away from the cylindrical connecting part 2 4330. The top external threaded shaft of the force sensor 4100 is cooperated and connected with the internal threaded hole 4310.

[0076] The sensor guide sleeve 4200 includes a guide sleeve body 4250 , a cylindrical hole 4220 is formed in the middle of the guide sleeve body 4250 , and a connecting protrusion 4240 is formed extending outward from the middle of the guide sleeve body 4250 . The connecting protrusion 4240 is hollow and communicates with the cylindrical hole 4220 .

[0077] The movable connecting part also includes a connecting block 4400, which is recessed inward to form a cavity for accommodating the sensor guide sleeve 4200. The bottom of the cavity of the connecting block 4400 includes a receiving groove 4430 and a fourth mounting hole 4420. The receiving groove 4430 is arranged in cooperation with the connecting protrusion 4240, and the fourth mounting hole 4420 is arranged in cooperation with the cylindrical hole 4220. The protrusions at both ends of the cavity of the connecting block 4400 are provided with three mounting holes 4410. The three mounting holes 4410 are arranged in cooperation with the three mounting interfaces 2211 on the mounting base 2200. The second mounting hole 4210 of the sensor guide sleeve 4200 is correspondingly connected with the seventh mounting hole 5300 on the mounting bracket 5000.

[0078] The mounting bracket 5000 includes a bracket plate 1 and a bracket plate 2 connected to each other. The bracket plate 1 is provided with a hollow load-carrying through hole 1 5400, and the hollow load-carrying through hole 1 5400 is arranged in cooperation with the through hole 2111 on the escape sleeve 2100. The bracket plate 1 is also provided with a mounting hole 5100, a mounting hole 6 5200, an insulating ring sleeve mounting hole 5500 and a ranging component mounting hole 5900. A wire groove 5600 is provided at the connection between the bracket plate 1 and the bracket plate 2. The side of the bracket plate 1 away from the bracket plate 2 is provided with an inner positioning ring 5800 and an outer positioning ring 5700. The inner positioning ring 5800 is arranged on the circumferential outside of the hollow load-carrying through hole 1 5400, and the outer positioning ring 5700 is arranged on the arc edge of the bracket plate 1.

[0079] The over-force release sleeve 2100 includes a protruding end 2120 , and the mounting base 2200 includes an embedded end 2230 and a cavity 2240 for accommodating the protruding end 2120 ;

[0080] The protruding end 2120 is embedded in the embedding end 2230 so that the over-force release sleeve 2100 is connected to the mounting base 2200;

[0081] The safety component 2300 is disposed on the outer peripheral side wall of the embedding end 2230 .

[0082] A preload spring 2400 is provided on the outer side of the embedded end 2230 , and the preload spring 2400 is configured to be in a compressed state when installed.

[0083] When the protruding end 2120 is embedded in the embedded end 2230, the preload spring 2400 is configured to be in a compressed energy storage state. When the embedded end 2230 is subjected to excessive pressure, the safety component 2300 will be overloaded and thus shrink. At this time, the preload spring 2400 pops up, thereby driving the over-force disengagement sleeve 2100 to separate from the mounting base 2200, completing overload protection and greatly improving overall safety.

[0084] The outer circumferential wall of the protruding end 2120 is recessed inward to form an annular groove 2122. A plurality of connection holes 2233 are provided in the corresponding areas where the embedded end 2230 contacts the annular groove 2122 of the protruding end 2120. The safety components 2300 are disposed one-to-one in the connection holes 2233. The outer side of the safety component 2300 is provided with a mounting thread 2340. An installation operation hole 2330 is provided at one end of the safety component 2300 away from the mounting thread 2340. The safety component 2300 further includes a ball 2310 and a load spring 2320 that contact each other. The load spring 2320 is disposed in the connection hole 2233 and is threadedly connected to the connection hole 2233 via the mounting thread 2340. When installed, the load spring 2320 is configured to be in a compressed state so that the load spring 2320 applies an elastic force to the ball 2310. When working normally, the load spring 2320 applies elastic force to the ball 2310 so that the ball 2310 extends outward and conflicts with the annular groove 2122 without being limited. When the protruding end 2120 receives too much load, the ball 2310 receives the thrust of the annular groove 2122 and moves inward, compressing the spring so that the annular groove 2122 and the ball 2310 are offset, thereby allowing the protruding end 2120 and the embedded end 2230 to move freely. At this time, since the preload spring 2400 is in a compressed energy storage state, the preload spring 2400 will bounce up and release, thereby driving the protruding end 2120 and the embedded end 2230 to separate and complete the overload protection work.

[0085] The size of the ball 2310 is adapted to the size of the connecting hole 2233 and the size of the cross section of the annular groove 2122 so that the ball 2310 can move in the connecting hole 2233 and the annular groove 2122 to ensure that the safety component 2300 can work normally and avoid the inability to complete the overload protection work due to the ball 2310 being stuck.

[0086] The number of the safety components 2300 or the elastic coefficient of the load spring 2320 is adapted to the required overload protection threshold size. The number of safety components 2300 can be freely matched or the load spring 2320 with different elastic coefficients can be selected according to the size of different types of overload protection thresholds, thereby improving the applicability of the threshold protection device and achieving a more humane and safe use experience.

[0087] The inner side surface 2232 of the embedded end 2230 is provided with a guide key 2234, and the raised end 2120 is provided with a guide groove 2121. The guide key 2234 and the guide groove 2121 are aligned in position and size to allow the guide key 2234 to fit within the guide groove 2121. The cooperation between the guide key 2234 and the guide groove 2121 not only facilitates the insertion of the raised end 2120 into the embedded end 2230, but also effectively prevents the raised end 2120 from deflecting within the embedded end 2230, thereby preventing the safety hazard of uneven forces acting on the various safety components 2300 due to the lack of deflection of the raised end 2120. Furthermore, during overload protection, the raised end 2120 is lifted vertically upward by the preload spring 2400, preventing it from becoming stuck and failing to complete the overload protection function due to deflection.
