Technical Field

[0001] This utility model relates to the field of exoskeleton structure technology, and in particular to an exoskeleton robot. Background Technology

[0002] Exoskeleton robots are widely used in military, industrial and rehabilitation fields. As a modern wearable device, exoskeleton robots are mainly used to enhance human mobility while providing protection for the wearer. With social progress and the acceleration of aging, human exoskeletons have developed rapidly.

[0003] In related technologies, exoskeleton robots include a waist module and two leg modules. The two leg modules are connected to the waist module. When the exoskeleton robot is in use, the waist belt of the waist module is worn on the user's waist, and the two leg modules are worn on the user's two legs respectively. The leg module includes a connecting structure and a wearing structure. The wearing structure is worn on the wearing area of ​​the user's legs, and the opposite ends of the connecting structure are connected to the waist module and the wearing structure respectively.

[0004] However, when users walk using exoskeleton robots, their legs are in a swinging state. In this situation, the distance between the wearing area on the user's legs and the user's waist changes. Consequently, the wearing area on the user's legs will rub against the wearing structure, causing friction damage to the user's legs. Utility Model Content

The rolling component is rotatably disposed at the other end of the first adjusting component. The connecting structure is connected to the waist module, and a long strip-shaped limiting cavity is provided in the connecting structure. The rolling component is rotatably disposed in the limiting cavity.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The following is for reference. Figures 1 to 5The exoskeleton robot of this application is described in detail.

[0037] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, an exoskeleton robot includes a waist module 10 and a leg module 20. The waist module 10 is worn on the user's waist. Two leg modules 20 are provided, each including a connecting structure 500 and a wearing structure 600. The wearing structure 600 includes a wearable component 610, a first adjusting component 620, and a rolling component 630. The wearable component 610 is connected to one end of the first adjusting component 620 and is worn on the user's legs. The rolling component 630 is rotatably disposed at the other end of the first adjusting component 620. The connecting structure 500 is connected to a waist belt 100 module. The connecting structure 500 has a long strip-shaped limiting cavity 521a. The rolling component 630 is rotatably disposed in the limiting cavity 521a. Under the action of external force, the rolling component 630 can roll along the limiting cavity 521a to drive the wearable component 610 closer to or away from the waist module 10.

[0038] Furthermore, when the exoskeleton robot of this application is used, the waist module 10 is worn on the user's waist, and the wearable parts 610 of the two leg modules 20 are worn on the user's two legs respectively, and the wearable parts 610 are worn in the wearing area of ​​the user's legs.

[0039] It should be noted that when a user walks using an exoskeleton robot, the distance between the wear area on the user's legs and the user's waist is constantly changing. If the distance between the wear piece 610 and the waist module 10 remains the same, in this case, the wear piece 610 and the wear area on the user's legs will rub against each other. Over time, the wear piece 610 will cause abrasions to the user's legs, affecting the user experience of the exoskeleton robot.

[0040] It is understood that in the exoskeleton robot of this application, the leg module 20 includes a connecting structure 500 and a wearing structure 600. The wearing structure 600 includes a wearable component 610, a first adjusting component 620, and a rolling component 630. The wearable component 610 is connected to one end of the first adjusting component 620 and is worn on the user's leg. The rolling component 630 is rotatably disposed at the other end of the first adjusting component 620. The connecting structure 500 is connected to the waist module 10. The connecting structure 500 has a long strip-shaped limiting cavity 521a. The rolling component 630 can roll... The device is positioned within the limiting cavity 521a. Thus, when a user wears the exoskeleton robot of this application and walks, the wearer 610 can be driven by the user's legs to push the rolling member 630 to roll along the limiting cavity 521a through the first adjusting member 620. This allows the relative distance between the wearer 610 and the waist module 10 to change in real time with the user's legs. Consequently, the relative movement between the wearer 610 and the wearing area of ​​the user's legs can be reduced, thereby reducing the abrasions caused by the wearer 610 to the user's legs.

[0041] It is understandable that, since the rolling element 630 is rotatably disposed on the first connecting member 200 and rotatably disposed within the limiting cavity 521a, the rolling element 630 can roll within the limiting cavity 521a along the extending direction of the limiting cavity 521a, so that the frictional force generated between the rolling element 630 and the cavity wall of the limiting cavity 521a can be reduced. As a result, when the user wears the exoskeleton robot of this application for walking, the wearable member 610 can more smoothly follow the user's leg relative to the connecting structure 500 to generate relative movement.

[0042] In some embodiments of this utility model, reference is made to Figure 2 The connecting structure 500 has a mounting hole 520a. The wall of the mounting hole 520a has an elongated mounting groove. The extension direction of the mounting hole 520a is parallel to the extension direction of the mounting groove. A limiting cavity 521a is formed in the mounting groove. The first adjusting member 620 is slidably inserted into the mounting hole 520a.

[0043] It is understandable that by providing a mounting hole 520a within the connecting structure 500, and allowing the first adjusting member 620 to slidably pass through the mounting hole 520a, the first adjusting member 620 can smoothly slide along the extension direction of the mounting hole 520a under the constraint of the hole wall. Since the extension direction of the mounting hole 520a is parallel to the extension direction of the mounting groove, the rolling member 630 can smoothly roll along the length direction of the limiting cavity 521a, thereby reducing the pressure between the rolling member 630 and the cavity wall of the limiting cavity 521a, and thus protecting the rolling member 630 and the cavity wall of the limiting cavity 521a. At the same time, the installation hole 520a also makes the connection between the first adjusting member 620 and the connecting structure 500 more stable.

[0044] In a further embodiment of this utility model, reference is made to... Figure 2 The connection structure 500 includes a first assembly block 521 and a second assembly block 522. The first assembly block 521 and the second assembly block 522 are detachably connected. The first assembly block 521 and the second assembly block 522 together define a mounting hole 520a, and a mounting groove is provided on the first assembly block 521.

[0045] Understandably, since the mounting hole 520a is formed between the first assembly block 521 and the second assembly block 522, the first assembly block 521 and the second assembly block 522 can be manufactured separately and then detachably connected to form the connection structure 500, which reduces the manufacturing difficulty of the connection structure 500.

[0046] In some embodiments of this utility model, reference is made to Figure 2 The mounting groove is a through groove that communicates with the outside of the mounting hole 520a.

[0047] It is understandable that by setting the mounting groove as a through groove, the rolling element 630 can be installed on the first adjusting element 620 located in the mounting hole 520a through the mounting groove, or the rolling element 630 installed on the first adjusting element 620 can be removed through the mounting groove; furthermore, by setting the mounting groove as a through groove, the installation and removal of the rolling element 630 can be facilitated.

[0048] Specifically, the rolling element 630 is a bearing.

[0049] Specifically, the cross-section of the mounting groove is waist-shaped.

[0050] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2The connecting structure 500 includes a second adjusting member 520 and a mounting base 510. The mounting base 510 is connected to the waist module 10. The second adjusting member 520 is hinged to the mounting base 510. A limiting cavity 521a is provided on the second adjusting member 520. Under the action of external force, the second adjusting member 520 can rotate relative to the mounting base 510 to move closer to or away from the other second adjusting member 520.

[0051] It is understandable that the distance between a user's two legs may change when the user is walking. Since the second adjustment member 520 is hinged to the mounting base 510, the two wearable members 610 can move closer or further away from each other as the user's legs move when the user is walking while wearing the exoskeleton robot of this application, thereby improving the user experience of the exoskeleton robot of this application.

[0052] Specifically, the second adjusting member 520 includes a detachable first assembly block 521 and a second assembly block 522.

[0053] In some embodiments of this utility model, reference is made to Figure 1 The waist module 10 includes a waist belt 100, a first connector 200, a second connector 300, and a locking structure 400. The waist belt 100 is worn on the user's waist. The first connector 200 and the second connector 300 are respectively connected to the opposite ends of the waist belt 100. The first connector 200 and the second connector 300 are slidably connected relative to each other in a preset direction. The locking structure 400 is provided on the second connector 300 and is used to lock or release the first connector 200.

[0054] It should be noted that waist circumference varies for users of different body types.

[0055] Understandably, when the exoskeleton robot of this application is worn, the waist belt 100 is wrapped around the user's waist, and the locking structure 400 achieves a fixed connection between the first connector 200 and the second connector 300, so as to realize the wearing of the waist module 10 on the user's waist. When the user feels that the waist belt 100 is too loose or too tight, the user can release the locking structure 400 from locking the first connector 200. At this time, the user can adjust the sliding of the first connector 200 relative to the second connector 300 in a preset direction to adjust the tightness of the waist belt 100, so that the waist module 10 of the exoskeleton robot of this application can be adapted to users of different body types.

[0056] In a further embodiment of this utility model, reference is made to... Figure 1 , Figure 3 and Figure 4The first connector 200 is provided with a plurality of snap-fit ​​grooves 221 spaced apart along a preset direction. The locking structure 400 includes a locking member 410 and an elastic connector 420. The locking member 410 is movably disposed on the second connector 300 and partially passes through the snap-fit ​​grooves 221. The elastic connector 420 is connected to the locking member 410 and the second connector 300 respectively, and is used to provide the elastic force to keep the locking member 410 snapped into the snap-fit ​​grooves 221. Under the action of external force, the locking member 410 can overcome the elastic force of the elastic connector 420 to disengage from the snap-fit ​​grooves 221.

[0057] Understandably, when the exoskeleton robot of this application is in use, the waist belt 100 wraps around the user's waist, the first connector 200 is connected to one end of the waist belt 100, and the second connector 300 is connected to the other end of the waist belt 100. The first connector 200 and the second connector 300 are slidably connected in a preset direction, and the locking member 410 is inserted into one of the snap-fit ​​slots 221 on the first connector 200 under the elastic force of the elastic connector 420, so as to achieve locking and fixation between the first connector 200 and the second connector 300. At this time, the waist module 10 can... The belt is securely worn around the user's waist. When the tightness of the belt 100 needs to be adjusted, the user can overcome the elastic force of the elastic connector 420 so that the locking member 410 disengages from the snap-fit ​​groove 221. At this time, the operator can drive the first connector 200 to move relative to the second connector 300 in a preset direction. After the tightness of the belt 100 is adjusted, the locking member 410 is released. At this time, the locking member 410 is inserted into another snap-fit ​​groove 221 under the elastic force of the elastic connector 420 to achieve locking and fixing between the first connector 200 and the second connector 300.

[0058] In some embodiments of this utility model, the second connector 300 has a connecting hole 301 extending along a preset direction, the first connector 200 is slidably inserted into the connecting hole 301, the side wall of the connecting hole 301 has an insertion hole 302, and the locking member 410 is slidably inserted into the insertion hole 302.

[0059] For example, such as Figure 1 , Figure 3 and Figure 4As shown, the first connector 200 and the second connector 300 are distributed in the left-right direction, and the second connector 300 is located to the left of the first connector 200. The right side of the first connector 200 is connected to one end of the belt 100, and the left side of the second connector 300 is connected to the other end of the belt 100. The second connector 300 is provided with a connecting hole 301 extending in the left and right directions, and the opening of the connecting hole 301 faces to the right. A vertically extending insertion hole 302 is provided on the upper side wall of the connecting hole 301. The locking member 410 is slidably inserted into the insertion hole 302 in the vertical direction. The snap-fit ​​grooves 221 on the first connector 200 are distributed at intervals in the left-right direction. The first connector 200 is inserted into the connecting hole 301 from right to left.

[0060] It is understandable that the connection hole 301 is designed so that the hole wall of the connection hole 301 can limit the first connector 200, so that the first connector 200 can slide stably along the preset direction.

[0061] In some embodiments of this utility model, the snap-fit ​​groove 221 is provided at one end of the first connector 200 away from the insertion hole 302, the locking member 410 has a hook portion 412a, the hook portion 412a extends to the side of the first connector 200 away from the insertion hole 302 and passes through the snap-fit ​​groove 221, and the elastic connector 420 is used to provide elastic force to keep the locking member 410 away from the connector hole 301 along the insertion hole 302.

[0062] For example, such as Figures 3 to 5 As shown, the slot of the snap-fit ​​groove 221 is set downward, and the lower end of the locking member 410 is provided with a hook portion 412a. Part of the structure of the hook portion 412a extends horizontally into the snap-fit ​​groove 221, so that the groove wall of the snap-fit ​​groove 221 can prevent the hook portion 412a from moving upward. The upper and lower ends of the elastic connector 420 are respectively connected to the locking member 410 and the second connector 300, and are used to provide elastic force to keep the locking member 410 moving upward.

[0063] Furthermore, under the elastic force of the elastic connector 420, the locking member 410 moves upward, so that the hook part 412a passes upward into the locking groove 221 and keeps the hook part 412a abutting the groove wall of the locking groove 221. When it is necessary to adjust the size of the belt 100, the user can overcome the elastic force of the elastic connector 420 to press the locking member 410 downward, so that the hook part 412a disengages downward from the locking groove 221. At this time, the user can smoothly drive the first connector 200 to move relative to the second connector 300 in a preset direction. After the user releases the locking member 410, under the elastic force of the elastic connector 420, the locking member 410 moves upward, so that the hook part 412a re-engages into a locking groove 221. At this time, the locking member 410 can prevent the first connector 200 from moving relative to the second connector 300 in a preset direction, so as to achieve locking and fixing between the first connector 200 and the second connector 300.

[0064] Understandably, users can unlock the first connector 200 and the second connector 300 by pressing the locking member 410, making it easier and more convenient for users to drive the locking member 410.

[0065] In some embodiments of this utility model, the locking member 410 includes a button 411 and a locking post 412. The locking post 412 is sequentially inserted into the insertion hole 302 and the connection hole 301. One end of the locking post 412 is detachably connected to the button 411, and the other end of the locking post 412 is bent to form a hook portion 412a. The button 411 can abut against the edge of the insertion hole 302 to prevent the button 411 from extending into the insertion hole 302.

[0066] For example, such as Figure 5 As shown, the locking member 410 includes a button 411 and a locking post 412. The locking post 412 is detachably connected to the lower end of the button 411. The locking post 412 passes through the insertion hole 302. The lower end of the locking post 412 extends into the connection hole 301 and is bent to form a hook portion 412a. The button 411 is located at the upper end of the insertion hole 302, and the button 411 can abut against the upper end hole edge of the insertion hole 302.

[0067] Understandably, by detachably connecting the locking pin 412 and the button 411 to form the entire locking member 410, the locking pin 412 and the button 411 of the locking member 410 can be manufactured as a single piece, reducing the manufacturing difficulty of the locking member 410; at the same time, the button 411 can abut against the upper edge of the through hole 302, which can effectively prevent the entire locking member 410 from being submerged in the through hole 302 due to excessive pressure from the user.

[0068] Specifically, the snap-fit ​​post 412 and the button 411 are connected by threaded connectors such as screws and bolts.

[0069] In some embodiments of this utility model, reference is made to Figure 5 The elastic connector 420 is a spring, which is sleeved on the snap-fit ​​post 412, and one end of the spring abuts against the button 411.

[0070] It is understandable that by fitting the spring onto the snap-fit ​​post 412, the snap-fit ​​post 412 can limit the spring, thereby reducing the probability of the spring automatically falling off during use; at the same time, the spring has a simple structure and low cost.

[0071] In some embodiments of this utility model, the button 411 is provided with an annular limiting stop 411a, the limiting stop 411a defines a limiting groove, the snap-fit ​​post 412 part passes through the limiting groove, and the spring part passes through the limiting groove.

[0072] For example, such as Figure 5 As shown, the lower end of button 411 is provided with an annular limiting stop 411a, which forms a limiting groove. The upper end of the locking post 412 passes through the limiting groove and is connected to button 411 through a threaded connector. There is an installation gap between the circumferential surface of the locking post 412 and the limiting stop 411a. A spring is sleeved on the locking post 412, and the upper end of the spring passes through the installation gap and abuts against the lower end of button 411.

[0073] Understandably, the setting of the limiting stop 411a allows the limiting stop 411a to cooperate with the snap-fit ​​post 412 to limit the spring, thereby reducing the deformation of the spring in the horizontal direction during operation; at the same time, the setting of the limiting stop 411a allows the limiting stop 411a to position the snap-fit ​​post 412 when the button 411 and the snap-fit ​​post 412 are connected, so as to facilitate the subsequent threaded connection of the button 411 and the snap-fit ​​post 412.

[0074] In some embodiments of this utility model, reference is made to Figure 5 The button 411 has a recessed pressing surface 411b at the end opposite to the locking post 412.

[0075] It is understandable that by providing a concave pressing surface 411b at the end of button 411 away from the locking post 412, the concave shape of the pressing surface 411b can adapt to the shape of the user's fingertip, thereby improving the user's feel when pressing button 411.

[0076] In some embodiments of this utility model, reference is made to Figure 4 The second connector 300 includes a first housing 310 and a second housing 320. The first housing 310 and the second housing 320 are detachably connected. The first housing 310 and the second housing 320 together define a connection hole 301 and an insertion hole 302.

[0077] It is understandable that by configuring the second connector 300 to be formed by the detachable connection of the first housing 310 and the second housing 320, the first housing 310 and the second housing 320 can be manufactured separately, thereby reducing the overall manufacturing cost of the second connector 300.

[0078] Specifically, the first housing 310 and the second housing 320 are detachably connected by threaded fasteners such as screws or bolts.

[0079] In some embodiments of this utility model, the first connector 200 includes a plate 210 and a snap-fit ​​part 220. The snap-fit ​​part 220 is disposed on the plate surface of the plate 210 and is integrally formed with the plate 210. The snap-fit ​​groove 221 is formed on the snap-fit ​​part 220.

[0080] For example, such as Figure 3 As shown, the first connector 200 includes a plate 210 and a snap-fit ​​part 220. The snap-fit ​​part 220 is disposed on the front plate surface of the plate 210, and the lower end of the snap-fit ​​part 220 is provided with a snap-fit ​​groove 221 with the opening facing downward.

[0081] It is understandable that by dividing the first connector 200 into a plate 210 and a snap-fit ​​part 220, and by setting the snap-fit ​​part 220 on the plate surface of the plate 210, the plate 210 can make the structural strength of the entire first connector 200 higher.

[0082] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
