Abstract
Description
Technical Field
[0001] The present invention relates to the field of manipulators, and particularly to a wearable power-assisted mechanical device for underground coal mines. Background Art
[0002] The replacement of manual labor by wearable power-assisted exoskeleton robots is an important development direction for coal mine equipment, and many achievements have been made. Wearable power-assisted exoskeleton robots are a cutting-edge technology that combines knowledge from multiple disciplines such as mechanical engineering, electronic engineering, and computer science. Their main purpose is to enhance human strength and improve human functions by wearing mechanical devices outside the human body, thereby achieving the goal of enhancing human work ability and improving human work efficiency. In the mine environment, wearable exoskeleton robots are particularly useful because they can help miners complete heavy physical labor such as carrying and excavation, while monitoring the safety of workers' lives.
[0003] In the prior art, in many situations such as complex roadway maintenance and the excavation of small chambers, due to limited space, cumbersome preparation work, or the protection of existing facilities, large equipment is not suitable for use. Conventional wheeled or tracked robots cannot adapt to complex environments, lack flexibility, and are also difficult to apply; manual handling is still required underground. When carrying heavy objects, the arms are bent forward, and the arm muscles are in a tense contraction state. Repeating this action frequently, the muscles will produce metabolic wastes such as lactic acid due to overuse. These metabolic wastes stimulate nerve endings, resulting in arm muscle fatigue and soreness. If heavy objects are carried for a long time, the arms need to maintain a bent state, which will cause a dull pain in the arms. If heavy objects are carried continuously in a state of muscle fatigue, more serious problems such as muscle strains may occur. Summary of the Invention

A cylindrical wire winding column D203 and a second wire threading frame D204 are installed between the upper support plate D201 and the lower support plate D202. A wire threading outlet D204.1 is provided on the second wire threading frame D204. The second wire threading frame D204 is opposite to the first wire threading frame D102. The wire threading outlet D204.1 is opposite to the wire threading inlet D102.1. The position of the wire threading outlet D204.1 is higher than that of the wire threading inlet D102.1.

The two rotating angles D206 are inserted into the channel-shaped part D101 and are connected through two frame body rotating shafts D205. As Figure 13 shown, each of the rotating angles D206 of the upper support plate D201 and the lower support plate D202 is connected to the first wire threading frame D102 through a buffer spring D3.
[0058] As Figure 12 shown, the traction wire C4 is wound around the buffer mechanism D. The specific wire winding method is as follows: After passing through the first guiding member, the traction wire C4 first passes through the wire threading inlet D102.1 on the first wire threading frame D102, then spirally winds around the wire winding column D203 for one circle, and then passes out through the wire threading outlet D204.1 of the second wire threading frame D204. The traction wire C4 does not cross on the wire winding column D203. When the user's arm moves quickly, the traction wire C4 will drive the rotating frame D2 to rotate and stretch the buffer spring D3, avoiding the concentrated force on the traction wire C4 at the first guiding member and preventing it from breaking.
[0059] Furthermore, the wire winding column D203 can be further improved to a variable diameter structure for adjusting the length of the traction wire C4 wound around the wire winding column D203.

[0063] Furthermore, in a specific embodiment of the present application, a large arm restraint device is provided inside the large arm support member B5, and the large arm restraint device is used to restrain the user's large arm. The large arm support member B5 is a long strip-shaped profile, as Figure 17The figure shows the installation structure diagram of the big arm binding device of the present invention. The front and rear surfaces of the big arm support B5 are provided with chutes along the length direction. The big arm binding device includes a first connecting seat B11 and a first strap B12. A rectangular channel is provided in the middle of the first connecting seat B11. The first connecting seat B11 is sleeved on the big arm support B5. The first connecting seat B11 is provided with sliders corresponding to the chutes of the big arm support B5, and the sliders of the first connecting seat B11 are slidably installed in the chutes; the first connecting seat B11 can adjust its position along the length direction of the big arm support B5. A positioning bolt is provided on the outer side surface of the first connecting seat B11, and the positioning bolt passes through the threaded hole on the outer side surface of the first connecting seat B11 and abuts against the big arm support B5; the position of the first connecting seat B11 on the big arm support B5 is fixed by the positioning bolt.

The big arm support B5 is bound to the user's big arm through the big arm binding device; the effect is as shown in 3. The forearm support B6 is a long strip-shaped profile. The upper end of the forearm support B6 is connected to the lower end of the big arm support B5 through a third rotating shaft B9; the bottom end of the forearm support B6 is connected to the holding member B7 through a fourth rotating shaft B10.
[0065] As Figure 1 shown in, in a specific embodiment of the present application, the holding member B7 is triangular, and a holding portion B13 is provided inside the holding member B7. The holding portion B13 can be made of a flexible material, such as an elastic band; the holding portion B13 can also be a rigid rod. Refer to Figure 3 shown in, when wearing, the user's hand passes through the holding portion B13. Refer to Figure 3 、 Figure 4 shown in, when the wearable outer armor A is worn on the user's upper body, the two assistive robotic arms B are located on the outer sides of the user's two arms, and the traction line C4 is tractioned from the front upper side of the arm.
[0066] The above assistive robotic arm B of the present invention can only rotate in one direction at the wrist joint and elbow joint. In a preferred embodiment, it can be improved to a more multi-directional rotational connection method, making the wrist joint and elbow joint more flexible.
[0067] As Figure 18The figure shows a structural diagram of an improved assisting robotic arm B of the present invention. As shown in the figure, between the upper arm support B5 and the forearm support B6, and between the forearm support B6 and the gripping member B7, they are connected by a movable joint E. The movable joint E is provided with three mutually perpendicular rotating shafts and two connecting bodies, which are respectively named the first joint rotating shaft E1, the second joint rotating shaft E2, the third joint rotating shaft E3, and the first connecting body E4 and the second connecting body E5 for the convenience of description. The first connecting body E4 and the second connecting body E5 are in the shape of a cuboid. On two adjacent surfaces of the first connecting body E4, the rotatable first joint rotating shaft E1 and the second joint rotating shaft E2 are respectively installed. The second joint rotating shaft E2 is vertically connected to the third joint rotating shaft E3. As Figure 18 shown in the figure, the second joint rotating shaft E2 is vertically connected to the middle position of the third joint rotating shaft E3; the second connecting body E5 is rotatably connected to the third joint rotating shaft E3. The first connecting body E4 and the second connecting body E5 are respectively connected to two different components.
[0068] As Figure 18 shown in the figure, between the upper arm support B5 and the forearm support B6, they are connected by a movable joint E. Specifically, the first joint rotating shaft E1 on the first connecting body E4 is rotatably connected to the bottom end of the upper arm support B5, and the second connecting body E5 is fixedly connected to the forearm support B6.
[0069] As Figure 18 shown in the figure, between the forearm support B6 and the gripping member B7, they are connected by a movable joint E. Specifically, the first joint rotating shaft E1 on the first connecting body E4 is rotatably connected to the bottom end of the forearm support B6, and the second connecting body E5 is fixedly connected to the outer surface of the gripping member B7.
[0070] In order to play a protective role, in a specific embodiment of the present application, the wearable outer armor A can be designed in the following form. Refer to Figure 1 、 Figure 2 shown in the figure, the front of the wearable outer armor A is provided with a chest guard A2. The chest guard A2 shown in the figure is an inverted trapezoidal plate, and the side of the chest guard A2 facing the human body is covered with a soft and breathable elastic sponge layer; after the chest guard A2 is worn, it is located at the chest position of the user. The upper edge of the chest guard A2 and the back support plate A1 are connected together by two shoulder straps A3. Each shoulder strap A3 shown in the figure is composed of two relatively wide elastic connecting bands, and the two shoulder straps A3 have elasticity and stretchability.
[0071] As Figure 1As shown in the figure, two wide strip-shaped elastic mounting straps A4 are symmetrically arranged below the breastplate A2. The bottom ends of the two elastic mounting straps A4 are each detachably connected to the waist belt A5 through a first buckle A6. The two ends of the waist belt A5 are connected to the waist armor A7, and the middle of the waist belt A5 is detachably connected through a second buckle A8. The two first buckles A6 are located on both sides of the second buckle A8. An abdominal armor A9 is installed between the two elastic mounting straps A4. The abdominal armor A9 is made of an elastic material, such as elastic rubber. The abdominal armor A9 shown in the figure is assembled by three abdominal plates A901. The abdominal plates A901 protrude forward and are composed of three non-coplanar surfaces. The two ends of the abdominal plates A901 are fixedly connected to the elastic mounting straps A4 on both sides. The side of the abdominal plates A901 facing the human body is a cavity and does not fit against the human abdomen. This design can avoid the impact force directly hitting the abdomen and play a role in protecting the abdomen. The adjacent abdominal plates A901 are rotatably connected through a pin shaft, so that the whole abdominal plates A901 can be bent. When the human body bends down, the abdominal plates A901 are bent and deformed so that this action can be smoothly completed. The abdominal armor A9 shown in the figure can be assembled by more abdominal plates A901. The more abdominal plates A901 there are, the stronger the bending and deformation ability of the abdominal plates A901. The three abdominal plates A901 shown in the figure are only examples and do not limit the number of abdominal plates A901.
[0072] As Figure 2 shown in the figure, the waist armor A7 is composed of two symmetrically arranged imitation bodies A701; the imitation bodies A701 are arc-shaped curved surfaces. As Figure 3 , Figure 4 shown in the figure, the imitation bodies A701 extend from the midline position of the waist on the back of the human body to the hip joint of the human body; as Figure 4 shown in the figure, the two imitation bodies A701 are located above the buttocks of the human body and respectively wrap around both sides of the human thighs. The two imitation bodies A701 are connected through a bendable elastic hip armor connecting piece A702. The hip armor connecting piece A702 can be made of elastic rubber. The hip armor connecting piece A702 shown in the figure is strip-shaped.
[0073] As Figure 2 shown in the figure, a cuboid-shaped battery pack A10 is arranged in the middle of the back of the wearable outer armor A. Electronic devices such as a storage battery A13 and a control circuit board are installed inside the battery pack A10. The storage battery A13 supplies power to the device. The surface of the battery pack A10 facing the human body is covered with a soft and breathable elastic sponge layer. The battery pack A10 is connected to the upper back support plate A1 through an elastic waterproof cloth A11, and the lower surface of the battery pack A10 is connected to the two imitation bodies A701 through two bendable elastic connecting pieces A12.
[0074] As Figure 19 shown is a partial structure display inside the battery pack A10 of the present invention Figure 1 . Figure 20The figure shows a partial structure display inside the battery pack A10 of the present invention. Figure 2 . In the illustrated embodiment, an installation base plate is provided inside the battery pack A10. A battery installation groove A14 is provided on the installation base plate. The battery installation groove A14 shown in the figure is a circular groove, and a total of four battery installation grooves A14 are provided. One circular storage battery A13 is installed in each battery installation groove A14. A battery case A15 is installed on the battery installation groove A14, and the battery case A15 covers the storage battery A13.
[0075] Since the storage battery A13 generates heat during charging and long-term power supply, in a specific embodiment, a cooling device is designed inside the battery pack A10. As Figure 20 shown in the figure, there is a gap between the battery case A15 and the storage battery A13 inside it. A cold air fan A16 is installed in the center of the battery case A15, and multiple air outlets A17 are provided on the side edge of the battery case A15; Temperature sensors are installed on the two circular surfaces of the storage battery A13. When the temperature of the circular surface outside the storage battery A13 is higher than the preset value, air is blown into the battery case A15 through the cold air fan A16, and the air is discharged from the air outlets A17 on the side of the battery case A15. In addition, a water cooling pipe A18 is embedded in the battery installation groove A14. The water cooling pipe A18 is preferably made of a copper pipe or a copper alloy pipe; The water cooling pipe A18 is spirally wound, and the water inlet port and the water return port of the water cooling pipe A18 are connected to different positions of the coolant storage tank A19, and a circulation pump A20 is installed on the water cooling pipe A18. Figure 20 In the figure, the water cooling pipes A18 of the upper two storage batteries A13 are connected in parallel, and the right circulation pump A20 is used for circulating cooling; The water cooling pipes A18 of the lower two storage batteries A13 are connected in parallel, and the left circulation pump A20 is used for circulating cooling.
[0076] Figure 20 In the figure, the coolant storage tank A19 is cylindrical, and the coolant storage tank A19 is embedded in the center of the installation base plate and is located in the middle of the four storage batteries A13. The coolant storage tank A19 is provided with an upward opening, and a plug that can be rotated and opened is provided on the opening. Coolant is added to the coolant storage tank A19 through the opening. When the temperature of the circular surface inside the storage battery A13 is higher than the preset value, cooling is carried out through circulating cooling.
[0077] In addition, in order to keep the coolant in the coolant storage tank A19 at a relatively low heat exchange temperature, a semiconductor refrigeration sheet is installed on the surface of the coolant storage tank A19. The cold end of the semiconductor refrigeration sheet is attached to the coolant storage tank A19. The coolant storage tank A19 is preferably made of copper or a copper alloy; The hot end of the semiconductor refrigeration sheet faces outward, and a heat sink A21 is installed, and a heat dissipation fan A22 is installed outside the heat sink A21 to accelerate the heat dissipation of the hot end of the semiconductor refrigeration sheet.
[0078] Furthermore, due to the restraint of the assisting robotic arm B, the user's arm cannot move flexibly and quickly to the face; when dust and smoke are generated underground, it is easy for the dust and smoke to block the line of sight; without shielding and protection for the eyes, sand getting into the eyes will affect the movement. Therefore, in a specific embodiment of the present invention, blowing devices F are provided on the two shoulders of the wearable outer armor A for blowing in front of the user's face to disperse the dust and smoke floating towards the face.
[0079] Specifically, as Figure 21 shown is the structural display diagram of the blowing device F on the right shoulder of the present invention. As Figure 21 shown in [reference], the right shoulder strap A3 clamps a cuboid-shaped mounting plate A23 at the shoulder position; in order to ensure that the mounting plate A23 remains horizontal, a wedge-shaped shoulder cushion A24 is installed below the mounting plate A23. The shoulder cushion A24 is preferably made of shape memory sponge and fits well with the shoulder. Figure 21 In the embodiment shown in [reference], a shoulder armor A25 is also rotatably connected to the outside of the shoulder cushion A24. The shoulder armor A25 is a curved surface shell that can cover the user's shoulder to prevent the assisting robotic arm B from rubbing the user's shoulder when its movement amplitude is too large.
[0080] The blowing device F mainly includes a support tube F1 that can be bent and deformed. The bottom end of the support tube F1 is installed on a rotating seat F2; the rotating seat F2 is rotatably installed on a bottom support seat F3. As Figure 22 shown is the internal structural schematic diagram of the bottom support seat F3 of the present invention. A driving gear F4 and a driven gear F5 that mesh together are arranged inside the bottom support seat F3. The driven gear F5 is connected to the bottom end of the rotating seat F2, and the driving gear F4 is connected to the driving shaft of an adjustment motor F6. As Figure 21 shown in [reference], a blowing shell F7 is installed at the top end of the support tube F1. The blowing shell F7 shown in the figure is a cylindrical tube with an open top end. The bottom of the blowing shell F7 is connected to the rotating seat F2 through an adjustment telescopic rod F8; the adjustment telescopic rod F8 adopts an electric telescopic rod B206 and is hinged to the blowing shell F7 and the rotating seat F2 at both ends respectively. An electric fan is installed inside and at the bottom of the blowing shell F7, and an air inlet hole is provided on the side of the blowing shell F7, and a dust filter F9 is installed on the air inlet hole.
[0081] In the blowing device F, the electric fan generates wind to blow in front of the user's face to prevent the dust and smoke from approaching the eyes and can also reduce the dust and smoke from entering the human body through the mouth and nose. In this device, the rotation of the support tube F1 is controlled by the adjustment motor F6 to adjust the blowing direction; the support tube F1 can also be controlled by the adjustment motor F6 to swing back and forth to expand the blowing range. In this device, the pitching angle of the blowing shell F7 is controlled by controlling the extension or shortening of the adjustment telescopic rod F8 to expand the blowing range.
[0082] Furthermore, in a specific embodiment of the present application, an inflatable buffer device may also be provided on the back of the wearable outer armor A. The main purpose of this device is that when the person wearing this equipment accidentally falls backward, the inflatable buffer device is used to form an inflatable cushion, and the inflatable cushion contacts the ground to prevent the back structure of this equipment from directly hitting the ground, causing personal injury and equipment damage.
[0083] Specifically, as shown in 2, two airbag storage cases G1 are symmetrically arranged on both sides of the battery pack A10. A rectangular airbag outlet is provided on the airbag storage case G1, and a buffer airbag G2 that rapidly expands after inflation is installed in the airbag outlet; an inflation device is arranged in the airbag storage case G1, and the inflation device is used to rapidly inflate the buffer airbag G2, so that the buffer airbag G2 rapidly expands and protrudes from the human back, as Figure 23 shown is a schematic diagram of the buffer airbag G2 after inflation in the present invention. The buffer airbag G2 is in a cuboid shape after inflation, and the included angle between the two buffer airbags G2 is less than 90 degrees, preferably 30 degrees - 80 degrees; as shown in the figure, the included angle between the two buffer airbags G2 is an acute angle, which can prevent the two buffer airbags G2 from shifting outward under pressure, resulting in support failure. In addition, the contact surface of the buffer airbag G2 after inflation is an inclined surface, Figure 2 in, the contact surface of the buffer airbag G2 after inflation is a wavy curved surface, and the length of the upper edge is longer than that of the lower edge, so that the contact surface is an inclined surface; the purpose of this design is to make the upper body of the human body form a certain angle with the ground after touching the ground, which is convenient for getting up.
[0084] In the present invention, the inflation device can be in various forms. For example, the present application does not limit the specific form of the inflation device. Scheme 1, the inflation device is a compressed gas tank (CO 2 gas tank). The compressed gas tank is arranged in the airbag storage case G1. The compressed gas tank is connected to the inflation port of the buffer airbag G2 through an air delivery pipe. An electromagnetic valve is arranged at the air outlet of the compressed gas tank or the inflation port of the buffer airbag G2, and inflation is carried out after the electromagnetic valve is opened. Scheme 2, the inflation device is an electric air pump. The electric air pump is connected to the inflation port of the buffer airbag G2 through an air delivery pipe; the electric air pump is installed in the airbag storage case G1. Embodiment 2
[0085] Furthermore, the wearable power-assisted mechanical equipment of the present invention can also be increased with a leg power-assisted device, such as Figure 24 shown is a structural display diagram of the first leg power-assisted device of the present invention. Figure 25This is a position display diagram of the first leg assist device after wearing the present invention. The first leg assist device includes a thigh assist rod H1, a thigh assist motor H2, and a thigh strap H3. The two thigh assist rods H1 are rotatably installed at both ends of the waist armor A7, on both sides of the human thigh; a thigh assist motor H2 is installed on the outer side of each thigh assist rod H1, and the thigh assist rod H1 is driven to rotate by the thigh assist motor H2 to assist the thigh lifting action. A thigh strap H3 is installed on the inner side of the thigh assist rod H1, and the thigh strap H3 is used to tie the user's thigh.
[0086] As Figure 26 This is a structural display diagram of the second leg assist device of the present invention. Figure 27 This is a display diagram of the second leg assist device after wearing the present invention. The second leg assist device mainly includes a thigh support arm J1, a calf support arm J2, and a foot support frame J3. The two thigh support arms J1 are rotatably connected to both ends of the waist armor A7, and a calf support arm J2 is rotatably connected to the bottom end of each thigh support arm J1. A foot support frame J3 is installed at the bottom end of the calf support arm J2. As Figure 27 shown, the rotation connection point between the thigh support arm J1 and the calf support arm J2 is located at the human knee joint, and the rotation connection point between the calf support arm J2 and the foot support frame J3 is located at the human ankle joint. Straps are respectively arranged on the inner sides of the thigh support arm J1 and the calf support arm J2 to bind the user's thigh and calf; the foot support frame J3 is used to accommodate the user's foot.
[0087] In order to meet the walking needs on uneven ground, the present invention provides a foot support frame J3 with multiple degrees of freedom. As Figure 28 shown is the structural display of the foot support frame J3 of the present invention Figure 1 . Figure 29 shown is the structural display of the foot support frame J3 of the present invention Figure 2As shown in the figure, the foot support J3 mainly includes a support shoe J301. The heel position on the side of the support shoe J301 is connected to the bottom of the calf support arm J2 through a foot joint J302. The foot joint J302 is assembled by a first foot joint connecting body J302.1, a second foot joint connecting body J302.2, a first foot joint connecting shaft J302.3, a second foot joint connecting shaft J302.4, and a third foot joint connecting shaft J302.5. The first foot joint connecting body J302.1 and the second foot joint connecting body J302.2 are cuboid-shaped. On the adjacent surfaces of the first foot joint connecting body J302.1, there are a first foot joint connecting shaft J302.3 and a second foot joint connecting shaft J302.4 that are perpendicular to each other. Among them, the first foot joint connecting shaft J302.3 is rotatably connected to the bottom of the calf support arm J2; the second foot joint connecting shaft J302.4 is rotatably connected to the second foot joint connecting body J302.2; the inner side surface of the second foot joint connecting body J302.2 is rotatably connected to the side of the support shoe J301 through the third foot joint connecting shaft J302.5; the third foot joint connecting shaft J302.5 is perpendicular to the second foot joint connecting shaft J302.4. The connection through three shafts makes the foot movement more flexible and can meet the walking requirements on uneven ground.
[0088] In addition, a reset structure can be provided on the foot support J3 to assist the foot movement in resetting. Specifically, as Figure 28 , Figure 29 shown, on the outer side surface and the heel position of the support shoe J301, there is a traction ear J301.1 extending upward. The traction ear J301.1 is connected to the bottom of the calf support arm J2 through a reset spring J303. A reset frame J304 made of an elastic material is led out from the rear side of the second foot joint connecting body J302.2. The reset frame J304 winds around from the rear of the heel of the support shoe J301 to another side of the support shoe J301. The reset frame J304 extends multiple connecting rods, and the connecting rods are connected to the sole of the support shoe J301 together. When walking on an uneven road surface, such as an inclined plane with a certain inclination, the support shoe J301 can rotate and step on the inclined plane. At this time, the reset spring J303 and the reset frame J304 are deformed and store energy. After the support shoe J301 leaves the inclined plane, the reset spring J303 and the reset frame J304 recover their deformation and drive the support shoe J301 to return to the horizontal state.
