[0101] Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the transmission mechanism of the present application. Figure 2 is based on Figure 1 The overall structure diagram of the transmission mechanism in another direction is shown. Figure 1 and Figure 2 The transmission mechanism 1 of the present application mainly includes at least one driven component 11 , a directional rotating member 12 and a transmission component 13 .
[0102] The driven component 11 and the transmission component 13 are interconnected to form a closed loop, which is used to be fixed to the body circumference position of an object. The driven component 11 can perform reciprocating linear actuation with the cyclic change of the body circumference of the object (i.e., the cyclic expansion and contraction of the chest circumference or abdominal circumference of the human body due to breathing), and the transmission component 13 is used to receive the reciprocating linear actuation of the driven component 11, so as to convert the reciprocating linear actuation into a directional rotational action and output it, thereby driving the directional rotating member 12 to perform a directional rotational action. In the embodiment of the present application, the object can be a human body or an animal, and the driven component 11 and the transmission component 13 are interconnected to form a belt tied to the chest or abdomen of the human body, so as to utilize the expansion and contraction changes of the chest circumference or abdominal circumference of the human body due to the breathing of the human body to provide the power source required by the present application. The driven component 11 forms a belt body, and the transmission component 13 can be enclosed in a housing as shown in 1, and an opening 1301 is respectively provided on both sides of the housing. The driven component 11 can be connected to the transmission component 13 through the opening 1301 to transmit the kinetic energy generated by the sensed chest and abdominal circumference changes to the transmission component 13. To simplify the description and facilitate understanding, the following will only take the driven component 11 and the transmission component 13 forming a waist belt and tied around the waist of the human body as an example to describe in detail the components of the present application.
[0103] The retractable member may be composed of an elastic material or a non-elastic material.
[0104] Figure 3 The following is a schematic diagram of the specific structure of the first embodiment of the driven component of the present application. As shown in the figure, the driven component 11 has a fixed member 111, a retractable member 112, and a driven member 113.
[0105] The fixing member 111 is a fixing belt body without elasticity, so that the transmission mechanism 1 can be firmly tied to the chest or abdomen of the human body.
[0106] The elastic and retractable member 112 is an elastic and retractable belt body, one end of which is axially fixedly connected to the fixing member 111, and the other end can be connected to the outer shell of the transmission component 11 to form a complete waist belt part, and the elastic and retractable member 112 can cyclically stretch and contract as the waist circumference of the human body expands and contracts periodically with breathing. That is, when the human body inhales, the waist circumference of the human body swells due to the air in the abdominal cavity, and the elastic and retractable member 112 will stretch and lengthen accordingly; when the human body exhales, the waist circumference of the human body shrinks due to the discharge of air in the abdominal cavity, and the elastic and retractable member 112 shrinks and shortens due to its own elastic restoring force.
[0107] The follower 113 has a first connection portion 1131 and a second connection portion 1132. As shown in the figure, the follower 113 is connected to the fixed member 111 via the first connection portion 1131, extends along the axial direction of the fixed member 111 and crosses the retractable member 112, and is connected to the transmission assembly 13 via the second connection portion 1132. Due to the cyclic extension and contraction of the retractable member 112, the follower 113 can perform reciprocating linear motion relative to the transmission assembly 13. In a specific embodiment, the follower 113 can be designed as a lead wire without elasticity.
[0108] Preferably, the driven component 11 also has a channel 114, which extends from a position adjacent to the first connecting portion 1131 (i.e., the position where the fixing member 111 is connected to the telescopic member 112) and axially penetrates the telescopic member 112, and ends at a position adjacent to the second connecting portion 1132 (i.e., the connection position between the elastic 112 and the transmission component 13), for providing the driven member 113 to pass therethrough. In this embodiment, the channel 114 can be in the shape of an elongated through hole.
[0109] However, the components of the driven assembly 11 are not Figure 3 Limits shown. See Figure 1In other embodiments, the driven component 11 may also be composed of only a fixed component 111A and a retractable component 112A, wherein the two ends of the retractable component 112A are respectively connected to the fixed component and the transmission component, and are used to cyclically stretch and contract with the cyclic changes in the circumference of the body surface of the object, and perform reciprocating linear motion relative to the transmission component 13. In this embodiment, the retractable component 112A can be composed of a non-elastic material.
[0110] Figure 4 This is a schematic diagram of the first embodiment of the transmission assembly of the present application. Figure 4 The transmission assembly shown is matched to Figure 3 The driven assembly shown in the figure is configured in the form of a driven assembly (ie, the transmission mechanism 1 is provided with only one driven assembly 11). In this embodiment, the transmission assembly 13 includes a base 1311, a first transmission structure 1312, and a first unidirectional rotating shaft 1313.
[0111] Base 1311 is Figure 1 A portion of a housing is shown.
[0112] A first transmission structure 1312 is disposed on the base 1311. The first transmission structure 1312 is connected to the driven member 113 of the driven assembly 11 and can rotate bidirectionally along with the reciprocating linear motion of the driven member 113. When the driven member 113 linearly moves toward a side away from the first transmission structure 1312, the first transmission structure 1312 rotates toward a first direction. When the driven member 113 linearly moves toward a side close to the first transmission structure 1312, the first transmission structure 1312 rotates toward a second direction.
[0113] The first unidirectional rotating shaft 1313 has a first rotating shaft outer ring 13131 and a first rotating shaft inner ring 13132 . The first rotating shaft outer ring 13131 is sleeved in the first transmission structure 1312 , and the first rotating shaft inner ring 13132 is fixedly connected to the directional rotating member 12 . Among them, when the first transmission structure 1312 rotates in the first direction, the first rotating shaft outer ring 13131 of the first unidirectional rotating shaft 1313 rotates in the first direction along with the first transmission structure 1312, and drives the first rotating shaft inner ring 13132 of the first unidirectional rotating shaft 1313 to rotate in the first direction, and the directional rotating member 12 rotates in the first direction; when the first transmission structure 1312 rotates in the second direction, the first rotating shaft outer ring 13131 of the first unidirectional rotating shaft 1313 rotates in the second direction along with the first transmission structure 1312, the first rotating shaft inner ring 13132 of the first unidirectional rotating shaft 1313 remains stationary, and the directional rotating member 12 remains stationary.
[0114] In addition, the transmission assembly 13 further has a first coil spring 1314, one end of which is fixedly connected to the base 1311, and the other end of which is fixedly connected to the first transmission structure 1312, wherein when the follower 113 is linearly actuated in a direction away from the first transmission structure 1312, the follower 113 applies a traction force to the first transmission structure 1312, so that the first transmission structure 1312 rotates in the first direction under the action of the traction force, and the first coil spring 1314 generates an elastic restoring force under the rotation of the first transmission structure 1312; when the follower 113 is linearly actuated in a direction close to the first transmission structure 1312, the traction force applied by the follower 113 to the first transmission structure 1312 is released, and the elastic restoring force generated by the first coil spring 1314 causes the first transmission structure 1312 to rotate in the second direction for resetting.
[0115] In a specific embodiment, the first transmission structure 1312 is a capstan 1312 having a first outer ring 13121 and a first inner ring 13122. The first one-way shaft 1313 is a one-way bearing 1313, but is not limited thereto. In other embodiments, the first one-way shaft 1313 may also be a ratchet or clutch structure. Among them, a first key groove 13123 is provided on the side wall of the first inner ring 13122 of the capstan 1312, and correspondingly, a second key groove 13133 is provided on the side wall of the first rotating shaft outer ring 13131 of the one-way bearing 1313. When the one-way bearing 1313 is sleeved in the first inner ring 13122 of the capstan 1312, the first key groove 13123 and the second key groove 13133 are aligned in the circumferential direction, and then a connecting key 1315 is inserted into the hole groove formed by the first key groove 13123 and the second key groove 13133, so that when the capstan 1312 rotates, the one-way bearing 1313 can be driven to rotate synchronously. One end (inner end) of the first coil spring 1314 is fixed to the base 1311 , and the other end (outer end) thereof can be connected to the first inner ring 13122 of the capstan 1312 via a through hole 13124 provided on the side wall of the first inner ring 13122 of the capstan 1312 .
[0116] When inhaling, the chest and abdominal circumference increases, and the follower 113 makes a linear motion from the side away from the capstan 1312, thereby pulling the first outer ring 13121 of the capstan 1312 to rotate in the first direction (i.e., in the direction of the follower 113), so that the first coil spring 1314 connected to the capstan 1312 generates an elastic restoring force, and the first rotating shaft outer ring 13131 of the one-way bearing 1313 rotates with the rotation of the capstan 1312, and the first rotating shaft inner ring 13132 of the one-way bearing 1313 also rotates therewith, and drives the directional rotating member 12 to rotate in the first direction. When exhaling, the chest and abdomen circumference decreases, and the follower 113 moves linearly from the side direction close to the capstan 1312, so that the traction force applied by the follower 113 on the capstan 1312 is released, and the elastic restoring force generated by the first coil spring 1314 is released, so that the capstan 1312 rotates in the second direction (i.e., opposite to the first direction) to reset, and at this time, the first rotating shaft outer ring 13131 of the one-way bearing 1313 also rotates together, but the first rotating shaft inner ring 13132 of the one-way bearing 1313 remains stationary, so that the directional rotating member 12 also remains stationary. With the alternation of breathing, the first rotating shaft inner ring 13132 of the one-way bearing 1313 rotates in only one direction, thereby realizing the directional output of the directional rotating member 12.
[0117] Figure 5 FIG. 1 is a schematic diagram of a specific structure of a second embodiment of a driven assembly of the present application. In this embodiment, the transmission mechanism 1 has two driven assemblies 11A and 11B, which are respectively disposed on two sides of the transmission assembly 13 . Figure 6 FIG. 2 is a schematic diagram of a second embodiment of the transmission assembly of the present application. Figure 5 In this embodiment, the transmission assembly 13 includes a first traction portion 1321 , a second traction portion 1322 , a first elastic body 1323 , a second elastic body 1324 , a first rack 1325 , a second rack 1326 , and a second unidirectional shaft 1327 .
[0118] The first and second traction parts 1321, 1322 are connected to the driven components 11A, 11B respectively. The two ends of the first rack 1325 are connected to the first traction part 1321 and the first elastic body 1323 respectively, and the two ends of the second rack 1326 are connected to the second traction part 1322 and the second elastic body 1324 respectively. The second one-way shaft 1327 has a second shaft outer ring 13271 and a second shaft inner ring 13272, wherein the second shaft outer ring 13271 is coupled to the first rack 1325 and the second rack 1326 respectively, and the second shaft inner ring 13272 is fixedly connected to the directional rotating member 12, so that the directional rotating member 12 rotates with the rotation of the second shaft inner ring;
[0119] When the first and second traction parts 1321 and 1322 are driven by the two driven components 11A and 11B to pull the first and second racks 1325 and 1326 to move in a direction away from the first elastic body 1323 and the second elastic body 1324, respectively, the first and second elastic bodies 1323 and 1324 generate elastic restoring forces; the second shaft outer ring 13271 of the second unidirectional shaft 1327 moves along with the first and second racks 1325 and 1326. The second unidirectional rotating shaft 1327 is actuated to rotate in the first direction, and at the same time drives the second rotating shaft inner ring 13272 to rotate in the first direction. When the actuating force of the two driven components 11A, 11B applied to the first and second traction parts 1321, 1322 is released, the elastic restoring force of the first and second elastic bodies 1323, 1324 causes the second rotating shaft outer ring 13271 of the second unidirectional rotating shaft 1327 to rotate in the second direction for restoration, and at the same time the second rotating shaft inner ring 13272 remains stationary.
[0120] In a specific embodiment, the first elastic body 1323 and the second elastic body 1324 are tension springs, and the second one-way rotating shaft 1327 is a ratchet 1327. However, this is not limited to the second one-way rotating shaft 1327, and the second one-way rotating shaft 1327 can also be a combination of a one-way bearing and a gear, and the one-way bearing and the gear can be integrally formed, so that they can be divided into two independent components, that is, the gear is set on the outer ring of the one-way bearing. When inhaling, the chest and abdominal circumference increases, and the follower 113A of the follower assembly 11A and the follower 113B of the follower assembly 11B pull the first and second racks 1325 and 1326 to move, so that the first elastic body 1323 and the second elastic body 1324 respectively generate an elastic restoring force, and the second rotating shaft outer ring 13271 of the ratchet 1327 rotates in the first direction with the actuation of the first and second racks 1325 and 1326, while driving the second rotating shaft inner ring 13272 to rotate together, and causing the directional rotating member 12 to rotate accordingly. When exhaling, the chest and abdomen circumference decreases, and the force applied by the follower 113A, 113B to the first and second racks 1325, 1326 is released. The first and second racks 1325, 1326 are reset under the elastic restoring force of the first elastic body 1323 and the second elastic body 1324, thereby driving the second shaft outer ring 13271 of the ratchet 1327 to rotate in the second direction (i.e., opposite to the first direction) to reset along with the reset action of the first and second racks 1325, 1326. At this time, the second shaft inner ring 13272 of the ratchet 1327 remains stationary, and the directional rotating member 12 also remains stationary. With the alternation of breathing, the second shaft inner ring 13272 of the ratchet 1327 rotates in only one direction, thereby realizing the directional output of the directional rotating member 12.
[0121] like Figure 2 or Figure 7As shown. Since the abdominal circumference of obese patients changes little, the energy generated is insufficient. Therefore, in the preferred embodiment of the present application, the transmission mechanism 1 also has an adjustment component 14, which is used to receive the reciprocating linear motion input by the driven component 11, and adjust the amplitude of the reciprocating linear motion to increase or decrease, and then output it to the transmission component 13. In other words, the adjustment component 14 can amplify the change of the chest and abdominal circumference of the human body, that is, the amplitude of the expansion and contraction of the driven component 11.
[0122] Optionally, the transmission mechanism also has an adjustment component, which is connected between the driven component and the transmission component, and is used to receive the reciprocating linear actuation input by the driven component, and adjust the actuation amplitude of the reciprocating linear actuation to increase or decrease and then output it to the transmission component.

[0126] The second capstan, the third gear and the fourth gear are installed on the second transmission shaft. At least one of the first transmission shaft and the second transmission shaft can be axially moved to make the first gear and one of the second gear mesh with one of the third gear and the fourth gear, so that the third gear or the fourth gear rotates and drives the second transmission shaft to rotate, and the second capstan is linked with the rotation of the second transmission shaft and drives the transmission assembly to reciprocate.

Among them, the number of teeth of the first and third gears 143, 145 is the same, the number of teeth of the second and fourth gears 144, 146 is the same, and the number of teeth of the first and third gears 143, 145 is twice the number of teeth of the second and fourth gears 144, 146. The first capstan 147 is connected to the driven component 11, and the second capstan 148 is connected to the transmission component 13. The first capstan 147, the first gear 143 and the second gear 144 are installed on the first transmission shaft 141. The first capstan 147 drives the first transmission shaft 141 to rotate by the telescopic action input by the driven component 11, thereby driving the first gear 143 or the second gear 144 to move in conjunction; the second capstan 148, the third gear 145 and the fourth gear 146 are installed on the second transmission shaft 142. At least one of the first transmission shaft 141 and the second transmission shaft 142 can be axially moved to mesh the first gear 143 with the fourth gear 146 or the second gear 144 with the third gear 145. The third gear 145 or the fourth gear 146 is engaged to rotate, and drive the second transmission shaft 142 to rotate, and the second capstan 148 is linked with the rotation of the second transmission shaft 142, and drives the transmission component 13 to perform telescopic actuation; when the first gear 143 is engaged with the fourth gear 146, the amplitude of the telescopic actuation of the transmission component 13 is twice that of the telescopic actuation of the driven component 11 (that is, the power output is doubled), and when the second gear 144 is engaged with the third gear 145, the amplitude of the telescopic actuation of the driven component 11 is twice that of the telescopic actuation of the transmission component 13 (that is, the power output is halved).
[0128] It should be noted that the above structure is only an embodiment of the adjustment component 14 of the present application, and the arrangement form and number of gears are not limited thereto and can be appropriately adjusted according to actual needs. In addition, the gears can also be replaced with pulleys.

In another embodiment of the present application, the mechanical energy of the directional rotation generated by the change of the chest and abdomen circumference can also be stored and output when needed. As shown in the figure, the transmission mechanism 1 of the present application also has an energy storage component 15, which includes: an energy release member 151, an output shaft 152, a third coil spring 153, a third unidirectional shaft 154, and an energy storage switch 155. Among them, the output shaft 152 is connected to the energy release member 151, the third coil spring 153 has an inner end and an outer end, the inner end is connected to the first unidirectional shaft 1313, the second unidirectional shaft 1327, or the directional rotating member 12, and the outer end is fixedly connected to the energy release member 151, and the third unidirectional shaft 154 is used to limit the inner end of the third coil spring 153 to drive the first unidirectional shaft 1313, the second unidirectional shaft 1327, or the directional rotating member 12 to reverse.

When the energy storage switch 155 locks the support so that the coil spring frame cannot rotate, the inner end of the third coil spring 153 is tightened as the first one-way rotating shaft 1313 or the second one-way rotating shaft 1327 rotates to store elastic energy, and the tightened third coil spring 153 is restricted by the third one-way rotating shaft 154 and cannot drive the first one-way rotating shaft 1313 or the second one-way rotating shaft 1327 to reverse. When the energy storage switch 155 is unlocked, the third coil spring 153 releases the elastic energy and drives the coil spring frame to rotate, so that the output shaft 152 rotates synchronously.
