Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or display that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or display.

In the prior art, some automation devices are provided with linear movement devices. As shown in fig. 1 to 3, in the field of transbronchial or transureteral examination or treatment, a more advanced technique is to use robotics to achieve insertion of a flexible endoscope or catheter. The flexible endoscope system is provided with linear movement means, i.e. an insertion arm 10, which insertion arm 10 comprises a first support 11, a second support 12 and a third support 13, the second support 12 being movable relative to the first support 11, the third support 13 being movable relative to the second support 12, the insertion of the endoscope or catheter being achieved by means of relative movement between the first support 11, the second support 12 and the third support 13. In order to avoid interference with other equipment in the operating room and to facilitate transport, the insertion arm 10 is of a relatively compact construction. The flexible endoscope system is equipped with various sensors such as vision, magnetic navigation, optical fiber navigation, tension and pressure, motor drive, and temperature, and pneumatic or liquid pipes are also used. The sensor cables or pipelines have strict use requirements, many cannot bear a slightly larger pulling force or have larger bending radius, and most of the sensor cables or pipelines cannot be replaced by other cables or pipelines.

Because the cable drag chain occupies a large space due to bending of the drag chain, there is often insufficient space to use the cable drag chain to protect the cable or the pipeline, or the bending radius of the cable or the pipeline after the cable drag chain is used is not satisfactory. Some reels are provided with a coil spring by which a cable or a pipe is wound. However, the torsion of the coil spring-based reel itself is related to the stroke, and there are problems that the cable or the pipeline is always subjected to a large pulling force due to the different torsion of the reel under different strokes and the pulling force is related to the stroke. To counteract the effect of such tension, if a reel is used to receive a cable or pipeline, it is necessary to use a cable or pipeline with a reinforcing braid or which itself can withstand a certain tension. However, in many cases, when the cable or the pipe of the terminal device is fragile and cannot be replaced, the cable or the pipe is always subjected to a large variable tensile force when the cable or the pipe is stored in the reel, and the service life of the cable or the pipe is affected.

Through repeated thinking and verification, the inventors found that if a housing device is designed, it includes a support member and a housing wheel rotatably mounted on a shaft body of the support member. The take-up wheel is configured to automatically rotate relative to the shaft. The flexible part can be wound around the storage wheel through rotation of the storage wheel, and meanwhile, the stress piece is wound on the storage wheel. When the flexible component is wound and stored by the storage wheel, the stress piece is utilized to bear most of the pulling force of the storage wheel, so that the flexible component is prevented from being damaged due to the fact that the storage wheel pulls the flexible component. The radius of the part used for winding the flexible part through the storage wheel can control the bending radius of the flexible part, so that the storage and the limiting of the flexible part can be realized in a device with a complex structure, the flexible part can not be pulled, the reliable protection of the flexible part is realized, and the service life and the reliability of the flexible part are further ensured.

The following describes in detail the technical solution of the storage device provided in the embodiment of the present application with reference to the accompanying drawings.

Referring to fig. 4 to 9, the storage device according to the embodiment of the present application is used for storing the flexible component 20, and the storage device includes a support 100, a storage wheel 200 and a force-bearing member 300. The support 100 includes a shaft 110. The accommodating wheel 200 is rotatably mounted on the shaft body 110, and the accommodating wheel 200 includes a first accommodating section 210 and a second accommodating section 220 coaxially disposed. A partition 230 is provided between the first receiving section 210 and the second receiving section 220, and the first receiving section 210 is configured to receive the flexible member 20 in a winding manner. The force-bearing member 300 has a strip structure, the first end of the force-bearing member 300 is fixed to the outer peripheral surface of the second accommodating section 220, and the force-bearing member 300 is wound around the second accommodating section 220. Wherein the receiving wheel 200 is configured to automatically rotate relative to the shaft body 110 to rotate around the receiving flexible member 20 and the force receiving member 300, respectively, and the force receiving member 300 is configured to receive a tensile force when the receiving wheel 200 rotates around the flexible member 20.

The flexible member 20 may be a cable or a combination of a cable and a pipeline, that is, the flexible member 20 is in a strip structure, and may be wound on the first storage section 210 along the length direction thereof. When the flexible member 20 is a cable, it may be a round cable, a flat cable, or a flat cable, i.e., the flexible member 20 may be circular or flat in cross-section, which is not limited only herein. The shaft body 110 has a circular cross-sectional shape, and illustratively, the receiving wheel 200 may be rotatably mounted on the shaft body 110 through a bearing 700. The first accommodating section 210 and the second accommodating section 220 are both cylindrical structures, and the lengths of the first accommodating section 210 and the second accommodating section 220 may be set as required, which is not limited herein.

In one possible implementation, the divider 230 may be a sheet-like annular protrusion with an outer edge that extends beyond the first receiving section 210 and the second receiving section 220, respectively. It will be appreciated that after the flexible member 20 is wound around the first receiving section 210, the outer diameter of the first receiving section 210 is the bending radius of the flexible member 20.

The cross section of the stress member 300 may be circular or flat, and those skilled in the art may set the stress member according to actual needs. It should be noted that, when the force-bearing member 300 is subjected to a tensile force, the length thereof is not changed. The strength of the force-bearing member 300 is required to ensure that it does not break when subjected to tensile forces. When the storage wheel 200 rotates, the stress piece 300 can bear most of the tensile force of the storage wheel 200, so that the flexible component 20 is prevented from being subjected to larger variable tensile force all the time when the storage wheel 200 rotates, and the service life of the flexible component 20 is ensured.

The application provides a storage device, which can store a flexible component 20 by rotating a storage wheel 200 on a shaft body 110, and can control the bending radius of the flexible component 20 by setting the radius of a first storage section 210 of the storage wheel 200. The first end of the force-bearing member 300 is fixed to the outer peripheral surface of the second receiving section 220, and the force-bearing member 300 is wound around the second receiving section 220. The stress piece 300 can bear most of the tensile force when the accommodating wheel 200 winds the flexible component 20, so that the flexible component 20 is prevented from being subjected to larger variable tensile force all the time when the accommodating wheel 200 rotates. The accommodating wheel 200 is provided with a partition 230 between the first accommodating section 210 and the second accommodating section 220, so that interference between the flexible member 20 and the force receiving member 300 is avoided. In this way, in the device with a relatively complex structure, the flexible component 20 can be stored and limited, the flexible component 20 can not be pulled, and further, the flexible component 20 can be reliably protected, and further, the service life and reliability of the flexible component 20 are guaranteed.

In one embodiment, as shown in fig. 7, the diameter D of the second receiving section 220 is greater than the diameter D of the first receiving section 210.

It should be noted that, when the flexible member 20 and the force receiving member 300 are assembled, it is required to be performed under the maximum stroke, that is, the flexible member 20 and the force receiving member 300 are separately under tension when assembled. When the storage wheel 200 rotates, the angular velocities of the first storage section 210 and the second storage section 220 are the same, and the bending radius of the flexible member 20 and the bending radius of the force receiving member 300 gradually increase as the storage wheel 200 rotates. Since D > D, the stroke of the force receiving member 300 is larger than the stroke of the flexible member 20 when the receiving wheel 200 is wound to receive the flexible member 20, it is understood that the stroke of the force receiving member 300 is also larger than the stroke of the flexible member 20 when the receiving wheel 200 is paying out the flexible member 20. In this way, when the receiving wheel 200 rotates, the force-bearing member 300 can mainly bear the pulling force of the receiving wheel 200.

Through the arrangement, the stress piece 300 can stably bear most of the tensile force provided by the storage wheel 200 when the storage wheel 200 rotates, and damage to the flexible component 20 due to the fact that the flexible component is always subjected to larger variable tensile force is avoided.

In one embodiment, as shown in fig. 7-10, a first limiting portion 240 is disposed at an end of the first receiving section 210 away from the separating portion 230, and a second limiting portion 250 is disposed at an end of the second receiving section 220 away from the separating portion 230. The shaft body 110 is provided with a first through hole 111, the axis of the first through hole 111 is parallel to the axis of the shaft body 110, the accommodating wheel 200 is provided with a second through hole 260, the shaft body 110 stretches into the second through hole 260, and the first limiting part 240 is provided with a wiring hole 241.

The first limiting portion 240 and the second limiting portion 250 are respectively formed as annular protrusions, wherein the outer edge of the first limiting portion 240 extends beyond the first accommodating section 210 and the second accommodating section 220, and the outer edge of the second limiting portion 250 extends beyond the first accommodating section 210 and the second accommodating section 220. In one possible implementation, the first through hole 111 is disposed coaxially with the shaft body 110.

Alternatively, the cross-sectional shape of the routing hole 241 may be an arc shape. Illustratively, after the shaft body 110 extends into the second through hole 260, the outer peripheral surface of the shaft body 110 is fixed to the inner ring of the bearing 700, and the hole wall of the second through hole 260 is fixed to the inner ring of the bearing 700.

With this structure, the flexible member 20 wound around the first receiving section 210 can be prevented from being separated from the first receiving section 210 by the first stopper 240 and the partition 230; the second limiting portion 250 and the separating portion 230 can prevent the force-bearing member 300 wound around the second receiving section 220 from being separated from the second receiving section 220. The first through hole 111, the second through hole 260 and the routing hole 241 provide routing channels for the flexible component 20, i.e. the flexible component 20 can extend between the first limiting part 240 and the partition part 230 and be fixed with the first receiving section 210 through the first through hole 111, the second through hole 260 and the routing hole 241, respectively.

In a specific embodiment, as shown in fig. 5, 6, 8 and 9, the receiving device further includes a platen 400. The outer periphery of the first accommodating section 210 is provided with a wire groove 211, and the wire groove 211 is communicated with the wire hole 241. The platen 400 is mounted to an opening of the wire chase 211, the platen 400 being configured to secure the flexible member 20.

Illustratively, the wire chase 211 may be disposed at the outer periphery of the first receiving section 210 by a one-shot molding process. Wherein the depth of the wire grooves 211 is not smaller than the diameter of the flexible member 20. It will be appreciated that the end of the routing hole 241 facing the partition 230 is located inside the wire slot 211. The pressing plate 400 may be fastened to the first receiving section 210 by a clamping, bonding, fastening, or the like, which is not limited herein.

In one possible implementation, the wire chase 211 has a first sidewall 212 disposed at an incline, and the flexible member 20 can be clamped and secured by the first sidewall 212 and the platen 400 after the platen 400 is secured at the opening of the wire chase 211. In another possible implementation, an adhesive layer may be disposed on a side of the platen 400 facing the wire chase 211, and the flexible member 20 may be adhesively secured by the adhesive layer after the platen 400 is secured to the first receiving section 210.

In this embodiment, by providing the wire slot 211 on the first accommodating section 210, the flexible member 20 can be turned in the wire slot 211 after extending from the wire hole 241 between the partition 230 and the first limiting portion 240, so that the accommodating wheel 200 can be wound to accommodate the flexible member 20 when rotating. The pressing plate 400 is installed at the opening position of the wire slot 211, and the flexible component 20 on the first storage section 210 can be fixed through the pressing plate 400, so that the flexible component 20 is prevented from moving.

In a more specific embodiment, as shown in fig. 5 and 6, the pressing plate 400 is disposed in an arc shape, one end of the pressing plate 400 is fixed to the side wall of the slot 211, and the distance between the side of the pressing plate 400 facing away from the slot 211 and the axis of the containing wheel 200 is equal to the outer diameter of the first containing section 210.

It will be appreciated that the pressure plate 400 is an arcuate plate and that, by way of example, fasteners may be used to lock the ends of the pressure plate 400 to the side walls of the trunking 211. It will be appreciated that, when the platen 400 is fixed to the opening of the slot 211, there is no difference in height between the side of the platen 400 facing away from the slot 211 and the position of the first receiving section 210 where the slot 211 is not provided.

In this structure, when the pressing plate 400 is installed at the opening position of the wire slot 211, and the flexible member 20 is wound on the first storage section 210 for a plurality of turns, the flexible member 20 cannot be bent at a small angle when passing through the wire slot 211, so as to ensure the bending radius of the flexible member 20 on the first storage section 210, and ensure the service life of the flexible member 20.

In one particular embodiment, as shown in fig. 6, 7 and 11, the force-bearing member 300 is a constant force coil spring.

The constant force coil spring is formed by winding a strip-shaped strip spring, is designed to have constant bending stress and can be unfolded, and has constant torque in the stroke range. It will be appreciated that the cross section of the constant force coil spring is flat, and the specific configuration of the constant force coil spring is not limited in this embodiment, and those skilled in the art can select a suitable constant force coil spring according to actual needs.

Illustratively, a first end of the constant force coil spring is secured to the first receiving section 210 and a second end of the constant force coil spring may be secured to the moving end of the linear motion device. For example, as shown in fig. 4, when the receiving device is mounted on the insertion arm 10, the second end of the constant force coil spring may be fixed to the third bracket 13. When the length of the insertion arm 10 is extended, the third bracket 13 may move the flexible member 20 and the constant force coil spring so that the receiving wheel 200 simultaneously discharges the flexible member 20 and the constant force coil spring; when the length of the insertion arm 10 is shortened, the constant force coil spring may provide a constant torque to the take-up wheel 200, so that the take-up wheel 200 automatically rotates relative to the shaft body 110 to wind up the take-up flexible member 20 and the constant force coil spring, respectively, at which time the constant force coil spring may bear most of the tensile force provided by the take-up wheel 200.

At present, some wire reels drive the wire reels to work through the motor so as to wind and receive cables or pipelines, and the wire reels need to use the motor, the speed reducer, the driver and the communication control unit, so that the control is complex and the cost is high.

In the storage device provided in this embodiment, the storage wheel 200 can be driven to rotate relative to the support member 100 by using the torque provided by the constant force coil spring to wind and store the flexible member 20, compared with a reel driven by a motor, the storage device does not need to use a motor, a speed reducer, a driver and a communication control unit, and is easier to arrange, simple to use and low in cost. In addition, the torque provided by the constant force coil spring is constant, namely, the torque provided by the constant force coil spring cannot be changed along with the length of the constant force coil spring extending out of the storage wheel 200, and meanwhile, the constant force coil spring bears most of the tensile force when the storage wheel 200 rotates, so that the flexible component 20 is prevented from being subjected to larger changed tensile force when the storage wheel 200 rotates, and the service life of the flexible component 20 is ensured.

In a more specific embodiment, as shown in fig. 5, 6, 7 and 10, the support 100 further includes a cover 120 located outside the shaft 110, and a portion of the constant force coil spring wound around the second receiving section 220 is located inside the cover 120. The side wall of the cover 120 is provided with a notch 121 through which the second end of the constant force coil spring extends.

Illustratively, the housing 120 includes an end wall and a side wall disposed about the end wall, and the shaft 110 of the support 100 is disposed through the end wall of the housing 120. The cover 120 and the shaft 110 may be fixed by screwing, clamping or bonding, or the cover 120 and the shaft 110 may be made into an integral piece. In one possible implementation, the end of the side wall of the housing 120 remote from the end wall may extend to the divider 230 of the take-up wheel 200 such that the portion of the constant force coil spring wound around the second take-up section 220 is located inside the housing 120.

Illustratively, the notch 121 in the cover 120 has a width that is greater than the thickness of the constant force coil spring such that the second end of the constant force coil spring extends from the notch 121 and is secured to the movable end of the linear motion device.

In this structure, the cover 120 can avoid the contact between the external impurities and the constant force coil spring or the bearing 700 between the shaft 110 and the storage wheel 200, so as to ensure the reliable operation of the storage device, and in addition, the side wall of the cover 120 is provided with a notch 121 for the constant force coil spring to extend out, so that the constant force coil spring can be connected with the moving end of the linear moving device, and the constant force coil spring can reliably drive the storage wheel 200 to rotate.

In one embodiment, as shown in fig. 6, 8, 9 and 11, the first end of the constant force coil spring is provided with a mounting section 310, the sidewall of the second receiving section 220 is provided with a fixing groove 221, and the mounting section 310 is inserted into the fixing groove 221 and fixed with the fixing groove 221.

Wherein the mounting section 310 is formed in a sheet-like structure, and illustratively, the mounting section 310 extends in a radial direction of the constant force coil spring when the constant force coil spring is in a wound state. It will be appreciated that the dimensions of the fixing groove 221 are matched to the dimensions of the mounting section 310 so that a worker projects the mounting section 310 into the interior of the fixing groove 221. It will be appreciated that the first end of the constant force coil spring can be secured to the second receiving section 220 after the mounting section 310 extends into the securing slot 221, and that the torque provided by the constant force coil spring can rotate the receiving wheel 200 relative to the support 100.

Through the arrangement, a worker is facilitated to connect the first end of the constant force coil spring with the second storage section 220, and the first end of the constant force coil spring is prevented from moving relative to the second storage section 220, so that the constant force coil spring can reliably drive the storage wheel 200 to rotate.

As shown in fig. 12 to 14, the storage device further includes a mainspring 500, and both ends of the mainspring 500 are connected to the shaft body 110 and the storage wheel 200, respectively. The force-bearing member 300 is a flexible member arranged in a strip shape.

It will be appreciated that the clockwork spring 500 is an energy storage spring, and the torque provided by the clockwork spring 500 varies with the angle of rotation of the clockwork spring 500, i.e., the greater the angle of rotation of the clockwork spring 500, the greater the torque provided by the clockwork spring. When the length of the linear movement device is extended, the receiving wheel 200 discharges the flexible member 20, and the mainspring 500 is elastically deformed at this time; when the length of the linear movement device is shortened, the receiving wheel 200 is driven by the elastic force of the mainspring 500 to automatically wind and receive the flexible member 20.

As shown in fig. 13, two ends of the clockwork spring 500 are a first fixed end 510 and a second fixed end 520, respectively, the first fixed end 510 is located at an inner ring of the clockwork spring 500, and the second fixed end 520 is located at an outer ring of the clockwork spring 500. The outer circumference of the shaft body 110 is provided with a first clamping groove 112, the second through hole 260 of the supporting member 100 is provided with a second clamping groove 263, the first fixing end 510 extends into the first clamping groove 112, and the second fixing end 520 extends into the second clamping groove 263, so that the clockwork spring 500 is connected between the shaft body 110 and the receiving wheel 200.

In one possible implementation, the second through hole 260 includes a first hole section 261 and a second hole section 262 coaxially disposed, the shaft body 110 passes through the second hole section 262 and protrudes into the interior of the first hole section 261, and the bearing 700 is disposed between the shaft body 110 and the first hole section 261 such that the receiving wheel 200 can rotate relative to the shaft body 110. The second bore section 262 has a diameter greater than the diameter of the first bore section 261, and the clockwork spring 500 may be connected between the second bore section 262 and the shaft 110.

Illustratively, a steel wire rope or other rope or wire having sufficient strength may be used as the force receiving member 300, in which case the force receiving member 300 has a circular cross-sectional shape. Since the diameter D of the second receiving section 220 is larger than the diameter D of the first receiving section 210, the stroke of the force receiving member 300 is larger than the stroke of the flexible member 20 when the receiving wheel 200 is rotated. Thus, when the clockwork spring 500 drives the storage wheel 200 to rotate, the stress piece 300 can bear most of the tensile force provided by the storage wheel 200, so that the flexible component 20 is prevented from bearing larger variable tensile force, and the service life of the flexible component 20 is ensured.

Compared with a reel driven by a motor, the storage device provided by the embodiment does not need a motor, a speed reducer, a driver and a communication control unit, is easier to arrange and is simple to use, and the cost is reduced. When the storage wheel 200 rotates, the stress piece 300 bears most of the tensile force provided by the storage wheel 200, so that the flexible component 20 is prevented from bearing larger changed tensile force, and the service life of the flexible component 20 is ensured.

As shown in fig. 6, 7, 12, 14 and 15, the storage device further includes a movement detection unit 600. The motion detection unit 600 includes a code wheel 610 and a reading head 620, the code wheel 610 is mounted at one end of the second storage section 220 far away from the first storage section 210, the reading head 620 is mounted on the support 100, and the reading head 620 is disposed opposite to the code wheel 610.

Illustratively, the code wheel 610 may be fixedly mounted to a side of the second spacing portion 250 remote from the separation portion 230 by fasteners. When the receiving wheel 200 rotates relative to the support 100, the code wheel 610 and the receiving wheel 200 can be driven to rotate synchronously. The code wheel 610 may have any suitable structure, such as a mechanical slot type, an optical type, a magnetic type, a capacitive type, or a spinning type, and the like, and is not limited thereto.

It will be appreciated that the read head 620 is mounted on the support 100 with the sensing end of the read head 620 facing the code wheel 610. When the receiving wheel 200 drives the code wheel 610 to rotate, the reading head 620 can read the movement parameters such as the rotation angle, the rotation angular velocity and the rotation acceleration of the code wheel 610. In one possible implementation, the reading head 620 may be electrically connected to a controller, and the controller may compare the motion parameters of the linear motion device and the rotation of the code wheel 610 to determine whether the flexible member 20 is abnormal.

In the prior art, the state of the flexible member 20 cannot be obtained in real time, when the flexible member 20 fails and cannot be found in time in the initial state, only when the flexible member 20 breaks or is irreversibly damaged. According to the storage device provided by the application, the state of the flexible component 20 can be obtained in real time by arranging the motion detection unit 600, and the state can be found out in time when the flexible component 20 breaks down, so that larger damage and injury are avoided.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
