TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an alignment locking system of a ceiling rail type H-shaped rail. BACKGROUND

[0002] The ceiling rail displacement system mainly consists of the following components: a rail system, a lifting main machine, a lifting tool and a lifting bag, and control and auxiliary equipment, etc., wherein the lifting main machine can move along the rail system, and the above components work together to realize safe patient transfer and rehabilitation training.

[0003] The H-shaped rail in the rail system is a flexible rail design. The H-shaped rail refers to two parallel rails fixed on the roof. The two parallel and fixed rails are called fixed rails. Another rail is slidingly connected between the two fixed rails. This sliding rail is called a movable rail, which is perpendicular to the two fixed rails and slidingly connected below the fixed rails.

[0004] In addition, the rail system has various types of rails, including straight rails and circular rails. The straight rails, circular rails and fixed rails are connected and fixed to the roof by a boom. The installation height of the straight rails, circular rails and movable rails is consistent. In this way, by configuring multiple types of rails, the lifting main machine can move on different types of rails, covering the entire treatment area.

[0005] Usually during use, when the movable rail of the H-shaped rail is aligned and connected with the straight rail or the curved rail, the switching of the lifting main machine can be realized, and the lifting main machine can freely slide. Therefore, the reliability of the connection between different rails is particularly important, which affects whether the lifting main machine can smoothly switch rails.

[0006] In the prior art, the connection between rails is usually achieved by inserting a pin into a socket, for example, CN118304114A discloses an H-rail automatic locking and ceiling rail main machine anti-displacement device, wherein the pin is inserted between the limiting block one and the limiting block two, and the pin is inserted to prevent relative displacement between the two rail sections. However, the reliability of this type of connection needs to be improved. SUMMARY

[0008] To achieve the above purpose, the technical solution adopted by the present application is:

[0014] Further, the positioning shaft is arranged at the front end of the plug rod, the locking shaft is close to the front end of the plug rod, the axis of the locking shaft is perpendicular to the driving plate, the locking shaft and the positioning shaft are arranged on two different height planes respectively, the locking shaft is matched with the positioning block, the positioning shaft is matched with the clamping claw, and the rear end of the plug rod is further provided with a push plate for driving the driving block to rotate.

[0015] Further, the active plate is provided with an active rotating shaft at the front side of the other side, and the active block is arranged at one end of the active rotating shaft. The active block is a long strip plate structure, and the upper end of the active block is exposed to the upper surface of the active plate to facilitate contact with the push plate and rotation of the active block by the push plate.

[0016] Further, the passive plate is a short plate body arranged horizontally, and the passive plate is connected and fixed with the end of the moving rail. The passive plate is provided with a mounting seat at one side. The mounting seat is a box body with a closed periphery and an open end. The mounting seat corresponds to the insertion rod, and the open end of the mounting seat faces the insertion rod. The clamping claw and the positioning block are arranged above and below the mounting seat respectively, and are located at different height positions.

[0017] Further, the positioning block is elastically and linearly slid in the mounting seat. A V-shaped groove is formed in the front end face of the positioning block, and the two sides of the V-shaped groove are tangent to the positioning shaft.

[0018] A spring rod is arranged at the rear end of the positioning block. The spring rod is a T-shaped circular rod structure, and one end of the spring rod penetrates out of the mounting seat.

[0022] A tension spring is arranged between each clamping claw and the mounting seat. The tension spring ensures the tension and is also the power source for the rotation of the clamping claw. The tension spring causes the outer protrusions at the two sides to move away from each other and the inner protrusions to move close to each other. The forward movement of the locking shaft against the inner protrusions causes the clamping claw to rotate and the outer protrusions to move close to each other and against the locking shaft.

[0023] Further, at least one end of the moving rail is arranged with the butt joint rail. The number of butt joint rails is consistent with the number of alignment locking devices.

[0024] Through the technical scheme, the application has the following beneficial effects:

[0025] When the moving rail and the docking rail are docked, the initial alignment is achieved by the mutual attraction of the magnetic ring one and the magnetic ring two, and after the alignment, the proximity switch senses the baffle to determine whether the moving rail and the docking rail are aligned, and after the alignment signal is stable, the subsequent extension of the insertion rod is stable, and then reliable docking is formed.

[0026] The active mechanism and the passive mechanism have a horizontal positioning function, which is achieved by the interaction of the positioning shaft and the V-shaped groove. When the insertion rod drives the positioning shaft to move forward and abut against the positioning block, the positioning shaft is tangent to the two sides of the V-shaped groove, thereby achieving the function of automatic centering positioning and ensuring that the moving rail and the docking rail are on the same horizontal plane. When the positioning block is pressed against the positioning shaft, the compression spring is compressed, and the two parts are tightly attached by the elastic force of the compression spring, thereby ensuring that the horizontal end faces of the rails are stably attached without movement.

[0027] The active mechanism and the passive mechanism have a locking function, which is achieved by the cooperation of the locking shaft, the guide groove, and the two freely rotating clamping jaws. When the insertion rod drives the locking shaft to move forward, the guide groove guides the locking shaft to enter it, and the cylindrical surface of the locking shaft and the arc surface at the inner end of the guide groove are concentrically aligned. During the alignment process, the locking shaft drives the clamping jaws to rotate, and the two clamping jaws cooperate to embrace the locking shaft, thereby locking the locking shaft.

[0028] When the lifting main machine changes rails, the insertion rod extends and retracts, which can drive the related push plate and push rod to move horizontally. The push rod rotates to lift and lower the passive stop block, and the push plate rotates to lift and lower the active stop block. When the active and passive stop blocks are lifted, the lifting main machine can freely move in the rail. When the active and passive stop blocks are lowered, the lifting main machine is blocked when it slides to the disconnected part of the rail, preventing the machine from running out of the rail and causing accidents.

DETAILED DESCRIPTION

[0044] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings:

[0046] H-shaped track is prior art, H-shaped track includes fixed rail 301 and movable rail 302, movable rail 302 is slidably connected below two fixed rails 301. Here the end of straight rail and annular rail is butt joint track 1, butt joint track 1 is arranged in parallel with movable rail 302 of H-shaped track and is located at the same height, lifting main machine 2 moves to straight rail or annular rail by butt joint track 1.

[0047] In order to realize the smooth rail replacement of lifting main machine 2, alignment locking device is provided at the joint of butt joint track 1 and movable rail 302, at least one end of movable rail 302 is arranged with butt joint track 1, here both ends of movable rail 302 are arranged with butt joint track 1, in turn, lifting main machine 2 can be moved to any butt joint track 1. The number of butt joint track 1 is consistent with the number of alignment locking device, so the number of alignment locking device is two, as shown in Figure 1 and Figure 2 .

[0048] In the embodiment, alignment locking device includes active mechanism 4 and passive mechanism 5, wherein active mechanism 4 is arranged on butt joint track 1, and passive mechanism 5 is arranged at the end of movable rail 302. Alignment locking device can realize the alignment operation of movable rail 302 and butt joint track 1, and can also lock movable rail 302 and butt joint track 1 after alignment, to ensure the reliable stability of the connection of the two tracks, and facilitate the smooth movement of lifting main machine 2 from movable rail 302 to butt joint track 1.

[0049] As shown in Figure 3 and Figure 4As shown, the driving mechanism 4 comprises a driving plate 6, a plug rod 7 linearly sliding along the driving plate 6, and a driving block 8 connected to the driving plate 6. The driving plate 6 is a horizontally arranged long plate body, and the driving plate 6 is fixedly connected with the docking track 1. The plug rod 7 is a long strip block body, and the sliding of the plug rod 7 is controlled by an electric push rod 9. Specifically, an electric push rod 9 for driving the plug rod 7 to linearly move is arranged at the rear side of one side of the driving plate 6, and the rear end of the plug rod 7 is connected with the electric push rod 9, so that the plug rod 7 can be driven by the electric push rod 9 to linearly reciprocate.

[0050] In order to improve the smoothness of the sliding of the plug rod 7, the plug rod 7 is slidingly connected with the driving plate 6 through a sliding rail and sliding block structure. That is, a sliding rail is installed above the driving plate 6, and a sliding block is installed below the plug rod 7, and the sliding block moves on the sliding rail, so that the smoothness and linear sliding of the plug rod 7 can be ensured. The movement direction of the plug rod 7 is consistent with the length direction of the docking track 1.

[0051] A positioning shaft 10 and a locking shaft 11 are sequentially arranged at the front end of the plug rod 7. The positioning shaft 10 and the locking shaft 11 are both cylindrical bodies, and the movement of the plug rod 7 can drive the positioning shaft 10 and the locking shaft 11 to move together. The positioning shaft 10 is arranged at the front end of the plug rod 7, and the locking shaft 11 is close to the front end of the plug rod 7, so that the positioning shaft 10 and the locking shaft 11 are sequentially arranged from front to back, and the locking shaft 11 and the positioning shaft 10 are arranged on two different height planes respectively. The axis of the locking shaft 11 is perpendicular to the driving plate 6, and the axes of the positioning shaft 10 and the locking shaft 11 are perpendicular to each other, so that the axis of the positioning shaft 10 is horizontally arranged.

[0052] The driving block 8 is used for controlling the on-off of the track changing movement path of the lifting host 2. The driving block 8 is a long strip plate structure, and both ends of the driving block 8 have V-shaped protruding structures. The driving block 8 can rotate on the driving plate 6. When the driving block 8 is installed, a driving rotating shaft 12 is rotationally arranged at the front side of the other side of the driving plate 6, and the driving rotating shaft 12 is installed on the driving plate 6 through two bearing seats. The driving rotating shaft 12 can only rotate in the circumferential direction, and cannot axially move. One end of the driving rotating shaft 12 is arranged with the driving block 8, so that the driving rotating shaft 12 and the driving block 8 rotate together.

[0053] Here, the lower end of the driving block 8 penetrates through the driving plate 6 and extends into the docking track 1, and the upper end of the driving block 8 is exposed on the plane of the driving plate 6. Specifically, a hole one 13 is formed on the driving plate 6, the hole one 13 penetrates through the docking track 1 downward, and the lower end of the driving block 8 can rotate into and out of the docking track 1 through the hole one 13. In the initial state, under the influence of the gravity of the driving block 8 itself, the lower end of the driving block 8 extends into the docking track 1 obliquely, and the driving block 8 abuts against one edge position of the hole one 13.

[0054] The straight-line forward movement of the insertion rod 7 will contact the upper end of the active stopper 8, and then push the active stopper 8 to rotate, so that the active stopper 8 rotates out of the docking track 1. Specifically, the rear end of the insertion rod 7 is further provided with a push plate 14 for driving the active stopper 8 to rotate, the insertion rod 7 drives the push plate 14 to move together, and the push plate 14 pushes the active stopper 8 to make the lower end of the active stopper 8 rotate out of the docking track 1, at this time the active stopper 8 no longer intercepts the rail changing movement path of the lifting host 2.

[0055] Two micro switches 15 are further arranged on the active plate 6 in a spaced manner, respectively sensing the extension to position and retraction to position signals of the insertion rod 7. The micro switch 15 is triggered by the push plate 14, during the movement of the push plate 14 following the insertion rod 7, the push plate 14 moves forward to contact one micro switch 15, indicating that the insertion rod 7 is extended to position, and the push plate 14 moves backward to contact another micro switch 15, indicating that the insertion rod 7 is retracted to position.

[0056] In addition, the front end of the active plate 6 is provided with a magnetic ring 16 and a proximity switch 17 on both sides. The magnetic ring 16 is a circular ring-shaped magnet, and the magnetic ring 16 and the proximity switch 17 are arranged between the docking track 1. The function of the magnetic ring 16 is that when the movable rail 302 needs to be aligned with the docking track 1, through the attraction characteristics of the opposite magnets, a hollow concentric alignment is formed between the movable rail 302 and the magnets of the docking track 1. When the magnetic rings between the movable rail 302 and the docking track 1 are concentrically aligned, the proximity switch 17 detects the signal, judges that the two tracks are in a preliminary alignment state, and thus the next action can be performed.

[0057] As shown in Figures 5 to 7 The passive mechanism 5 includes a passive plate 18, a positioning block 19 elastically sliding along the passive plate 18, a clamping jaw 20, and a passive stopper 21 connected to the passive plate 18. The passive plate 18 is a horizontally arranged short plate body, and the passive plate 18 is fixedly connected with the end of the movable rail 302. The active plate 6 is consistent in width with the passive plate 18.

[0058] The positioning block 19 and the clamping jaw 20 are provided with a mounting seat 22 on one side of the passive plate 18 during installation, and the mounting seat 22 corresponds to the insertion rod 7. The mounting seat 22 is a rectangular box body with a closed periphery and an open end, and the open end of the mounting seat 22 faces the insertion rod 7. The clamping jaw 20 and the positioning block 19 are arranged on the mounting seat 22 in an upward and downward manner, respectively.

[0059] The positioning block 19 elastically and linearly slides in the mounting seat 22, and reciprocally slides between the open end and the closed end of the mounting seat 22. Meanwhile, a spring rod 23 is arranged at the rear end of the positioning block 19, and the spring rod 23 is a T-shaped circular rod structure. One end of the spring rod 23 penetrates out of the mounting seat 22, and the spring rod 23 is in sliding connection with the mounting seat 22. A compression spring 24 is sleeved on the spring rod 23 in the mounting seat 22. The compression spring 24 tends to elongate, thereby driving the spring rod 23 to extend into the mounting seat 22, and at the same time, the positioning block 19 also moves forward to the open end of the mounting seat 22.

[0060] The front end surface of the positioning block 19 is provided with a V-shaped groove 191 matched with the positioning shaft 10. When the positioning shaft 10 moves forward and contacts the positioning block 19, the V-shaped groove 191 is tangent to the positioning shaft 10 at both sides, and drives the positioning block 19 to move linearly backward, so that the compression spring 24 is compressed, and the spring rod 23 gradually extends out of the mounting seat 22.

[0061] The passive plate 18 is symmetrically connected with clamping claws 20 on both sides, that is, the mounting seat 22 is provided with clamping claws 20, and the clamping claws 20 and the positioning block 19 are arranged in an upper and lower interval. Two clamping claws 20 can clamp and lock the shaft 11, so as to lock the forwardly extended locking shaft 11, preventing the locking shaft 11 from being separated from the passive mechanism 5.

[0062] The clamping claw 20 is a horizontally arranged plate body, and the clamping claw 20 is provided with a clamping groove 201. The clamping grooves 201 on the two clamping claws 20 are arranged in a "()" shape, and the clamping grooves 201 are irregular in outline. Two clamping grooves 201 cooperate to clamp the locking shaft 11. Moreover, each clamping groove 201 is provided with an inner protrusion 25 at the inner end and an outer protrusion 26 at the outer end, and the outer protrusion 26 is located at the opening end of the mounting seat 22.

[0063] In the initial state, the two clamping grooves 201 are in an open state, that is, the two outer protrusions 26 are away from each other, and the inner protrusions 25 are close to each other. In order to realize this state, a tension spring 27 is arranged between each clamping claw 20 and the mounting seat 22, which promotes the horizontal rotation of the clamping claw 20. In order to limit the rotation angle of the clamping claw 20, an arc-shaped limiting groove 28 is arranged on the clamping claw 20, and a limiting bolt 29 is arranged above the mounting seat 22, which vertically penetrates the limiting groove 28. The limiting bolt 29 cooperates with the limiting groove 28 to limit the rotation of the clamping claw 20.

[0064] In this way, the tension spring 27 promotes the two clamping grooves 201 to move away from each other, so that the outer protrusions 26 on both sides are away from each other, and the inner protrusions 25 are close to each other, and the clamping grooves 201 are in an open state. When the locking shaft 11 moves forward between the two clamping grooves 201, the locking shaft 11 first abuts against the inner protrusion 25, so that the clamping claw 20 rotates, and the outer protrusions 26 are close to each other and abut against the locking shaft 11, which is equivalent to clamping the locking shaft 11 by the two clamping claws 20, preventing the locking shaft 11 from being separated from the clamping claw 20.

[0065] In order to ensure that the locking shaft 11 can accurately enter between the two clamping grooves 201, a trumpet-shaped guide groove 30 is opened on the upper side wall of the mounting seat 22, the inner end of the guide groove 30 is a circular arc surface, the guide groove 30 and the opening of the mounting seat 22 are arranged up and down, the guide groove 30 faces the insertion rod 7, and the mounting seat 22 on both sides of the guide groove 30 is symmetrically arranged with the clamping claw 20. The insertion rod 7 drives the locking shaft 11 to be inserted into the guide groove 30, and the locking shaft 11 is guided by the guide groove 30, so that the locking shaft 11 accurately enters between the two clamping grooves 201, and it is ensured that the locking shaft 11 can be effectively locked by the clamping claw 20. When the locking shaft 11 enters the inner end of the guide groove 30, the circular arc surface at the inner end of the guide groove 30 is concentric with the cylindrical surface of the locking shaft 11.

[0066] The passive block 21 has the same effect and similar structure as the active block 8. The mounting structure of the passive block 21 is referred to the active block 8, which will not be repeated here. The lower end of the passive block 21 penetrates through the passive plate 18 and extends into the moving rail 302. Through the rotation of the passive block 21, the movement of the lifting main body 2 in the moving rail 302 can be controlled. The passive block 21 rotates out of the moving rail 302 and relies on the positioning block 19. The rear movement of the positioning block 19 can drive the passive block 21 to rotate out of the moving rail 302 and no longer hinder the movement path of the lifting main body. Specifically, a push rod 31 is arranged on one side of the positioning block 19, the push rod 31 extends out of the mounting seat 22, and the positioning block 19 drives the passive block 21 to rotate through the push rod 31.

[0067] In addition, a magnetic ring two 32 matched with the magnetic ring one 16 and a baffle 33 matched with the proximity switch 17 are arranged on both sides of the front end of the passive plate 18, and the baffle 33 is made of iron. The magnetic ring one 16 and the magnetic ring two 32 are two magnets with different magnetic poles, and when the magnetic ring one 16 and the magnetic ring two 32 correspond to each other and are concentrically aligned with a space therebetween. At the same time, the proximity switch 17 detects the baffle 33 to determine that the docking rail 1 and the moving rail 302 are in a preliminary alignment state, and then the next operation is performed.

[0068] The next operation is that the insertion rod 7 drives the positioning shaft 10 and the locking shaft 11 to move forward synchronously, so that the insertion rod 7 pushes the active block 8 to rotate out of the docking rail 1. Also, the positioning shaft 10 extends forward to push the positioning block 19 to move backward and drive the passive block 21 to rotate out of the moving rail 302, and the locking shaft 11 extends forward between the two clamping claws 20, and the two clamping claws 20 cooperate to clamp the locking shaft 11, so as to realize the alignment and locking operation of the docking rail 1 and the moving rail 302.

[0069] The principle of the present application is that in a free state, the movable rail 302 can slide between the two fixed rails 301, and the lifting host 2 can move back and forth on the movable rail 302, at this time, the lifting host 2 can move freely in all directions within the area surrounded by the two fixed rails 301. When the lifting host 2 needs to change rails, the movable rail 302 is manually pulled to the position that needs to be aligned, so as to align the movable rail 302 with the two docking rails 1, as shown in Figure 8 During the above process, the electric push rod 9 on the docking rail 1 is in a retracted state, and the clamping jaws 20 at both ends of the movable rail 302 are in an open state.

[0070] When the movable rail 302 is preliminarily aligned with the docking rail 1, the magnetic ring one 16 on the docking rail 1 and the magnetic ring two 32 on the movable rail 302 are opposite magnets, and further attract each other to preliminarily align the movable rail 302 with the docking rail 1. When the movable rail 302 is preliminarily aligned with the docking rail 1, the proximity switch 17 on the docking rail 1 monitors the baffle 33 on the movable rail 302, at this time, the movable rail 302 and the docking rail 1 are in a stable alignment state, and the proximity switch 17 feeds back a signal to the controller, and the next action is controlled by the controller.

[0071] When the movable rail 302 and the docking rail 1 maintain a stable alignment state, the electric push rod 9 is still in a retracted state, the push plate 14 does not contact the active stop block 8, and the active stop block 8 extends into the docking rail 1 by virtue of its own weight, blocks the movement of the lifting host 2, and prevents it from moving out of the rail. Moreover, the push rod 31 is in the front end position of the mounting seat 22 under the action of the compression spring 24, and the push rod 31 does not contact the passive stop block 21, and the passive stop block 21 extends into the movable rail 302 by virtue of its own weight, blocks the movement of the lifting host 2, and prevents it from moving out of the movable rail 302, as shown in Figure 9 .

[0072] After the movable rail 302 and the docking rail 1 maintain a stable alignment state, the controller receives a signal and then controls the electric push rod 9 to extend, which drives the insertion rod 7, the positioning shaft 10, the locking shaft 11 and the push plate 14 to move forward together and approach the passive mechanism 5. The positioning shaft 10 first contacts the positioning block 19, the cylindrical surface of the positioning shaft 10 is in tangential contact with the two sides of the V-shaped groove 191 on the positioning block 19, and the compression spring 24 is compressed to generate deformation, and the elastic potential energy of the compression spring 24 gradually increases, as shown in Figure 10 and Figure 11 .

[0073] After the electric push rod 9 is extended to the position, the positioning shaft 10 abuts against the positioning block 19, at this time, the compression spring 24 is compressed to the maximum deformation, so as to align the movable rail 302 with the docking rail 1 in the upper and lower horizontal planes, and realize the tight abutment of the positioning shaft 10 and the positioning block 19 through the elastic force of the compression spring 24, so as to ensure that the upper and lower horizontal end surfaces of the two rails are stably and stably attached, that is, to ensure that the two rails are on the same horizontal plane.

[0074] In the process of the electric push rod 9 extending forward, in addition to the action of the positioning shaft 10 moving forward to press the positioning block 19, there are also the following actions: 1, the locking shaft 11 gradually approaches the guide groove 30 and accurately enters the guide groove 30 under the guidance of the guide groove 30. At the same time, since the two outer protrusions 26 are away from each other and do not affect the locking shaft 11 entering the clamping groove 201, the locking shaft 11 moves forward to touch the inner protrusion 25, drives the clamping jaw 20 to rotate by a certain angle, thereby the tension spring 27 is stretched, and the two outer protrusions 26 gradually approach and tightly abut against the edge of the locking shaft 11, forming an action of embracing the locking shaft 11, until the electric push rod 9 extends to the position, and the clamping groove 201 on both sides embraces the locking shaft 11, as shown in Figure 12 .

[0075] As long as the electric push rod 9 remains in the extended state, the clamping groove 201 can always embrace the locking shaft 11 without loosening, at this time the tension spring 27 is deformed by being pulled and maintains a certain tension. Since the locking shaft 11 is concentric with the cylindrical surface of the guide groove 30 when the locking shaft 11 is at the inner end of the guide groove 30, this can ensure that the docking track 1 and the movable track 302 are on a straight line, accurate alignment and stable connection.

[0076] 2, the insertion rod 7 moves forward to drive the push plate 14 to move forward, in the process of the push rod 31 moving forward, the driving block 8 is rotated by a certain angle, the lower end of the driving block 8 is rotated out of the docking track 1, allowing the lifting main machine 2 to move. In the process of the positioning shaft 10 tightly abutting against the positioning block 19 moving backward, the push rod 31 moves together, the push rod 31 pushes the passive block 21 to rotate by a certain angle, the lower end of the passive block 21 is rotated out of the movable track 302, also allowing the lifting main machine 2 to move, as shown in Figure 13 and Figure 14 .

[0077] In this way, under the premise of the positioning shaft 10 pressing the positioning block 19, the clamping jaw 20 on both sides embracing the locking shaft 11, the driving block 8 rotating out of the docking track 1, and the passive block 21 rotating out of the movable track 302, the lifting main machine 2 can be moved from the movable track 302 to the docking track 1, realizing the smooth rail switching operation of the lifting main machine 2.

[0078] After the rail switching is completed, when the movable track 302 needs to be freely movable, the electric push rod 9 changes from the extended state to the retracted state, in this process: the locking shaft 11 gradually separates from the clamping jaw 20, the clamping jaw 20 is rotated back to the initial position under the action of the tension spring 27; the positioning shaft 10 retreats, the positioning block 19 moves forward under the action of the compression spring 24, the passive block 21 is gradually released, and the passive block 21 rotates back to the movable track 302 again by relying on the weight. At the same time, the push plate 14 no longer contacts the driving block 8, and the driving block 8 rotates back to the docking track 1 by relying on the weight. At this time, the movable track 302 can be freely movable, and the lifting main machine 2 is also limited by the driving block 8, which can prevent the lifting main machine 2 from accidentally falling off the docking track 1.

[0079] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the scope of the present application. Accordingly, all equivalent changes or modifications which are made based on the above-described embodiments are included in the scope of the present application.
