Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a foldable stretcher-type exoskeleton device. Background Technology

[0002] In recent years, global disasters have occurred frequently. The complex situations at disaster sites have hindered firefighters from providing immediate assistance. Conventional, manually operated firefighting and rescue equipment is ineffective in severely damaged and extremely unstable environments, posing a serious threat to the lives of rescue personnel. Rescue sites often cause severe damage to roads and buildings over large areas, forcing rescuers to carry heavy rescue equipment on foot, making rescue work even more difficult. Or, when rescuers reach the scene, rescue vehicles cannot enter, and rescuers must carry the injured out on stretchers. The repeated stretcher carrying can completely exhaust the rescuers' physical strength.

[0003] Therefore, in response to the heavy physical labor and prolonged physical exhaustion faced by firefighters in the rescue of major urban accidents, a firefighting exoskeleton robot designed for major rescue and disaster relief missions has been developed. This wearable human assistive intelligent device integrates assistance and safety protection. Through the docking, fusion, and collaboration between the human and the exoskeleton, it breaks through physiological limits, enhances human function, and can play a highly efficient human assistive role in various emergency rescue situations such as carrying heavy loads, climbing stairs, breaking through obstacles, rescuing people, and carrying stretchers. It significantly reduces the physical exhaustion of rescue personnel, improves the efficiency of rescue work, and increases the continuous working time.

[0004] However, commercially available exoskeletons designed for stretcher transport are not convenient for packaging and carrying due to their complex structure, numerous parts, and non-foldable one-piece design, which take up a lot of space.

[0005] In view of this, it is necessary to propose further improvements to the current foldable stretcher-type exoskeleton structure. Summary of the Invention

[0006] Therefore, the purpose of this invention is to at least partially address the shortcomings of the prior art, thereby proposing a foldable stretcher-type exoskeleton device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This invention provides a foldable stretcher-type exoskeleton device, including a shoulder bone support and a spine support connected to each other. The spine support includes a first spine support connector and a second spine support connector that are rotatably connected to each other. A shoulder joint locking tube is connected to each end of the shoulder bone support on the side away from the spine support. A hook stretcher component is connected to the end of the shoulder joint locking tube away from the shoulder bone support. A locking adjustment seat is connected to the end of the shoulder joint locking tube near the shoulder bone support. The shoulder joint locking tube is movably engaged with the shoulder bone support through the locking adjustment seat.

[0009] Furthermore, the locking seat includes a locking housing with a first limiting groove, and a wide locking tongue is movably connected in the first limiting groove. The wide locking tongue can reciprocate relative to the locking housing to lock or disengage the shoulder joint locking tube from the shoulder bone support.

[0010] Furthermore, the shoulder bone support member has a protrusion on the side near the shoulder joint locking tube. The protrusion engages with the wide locking tongue. When the wide locking tongue moves relative to the locking housing, the wide locking tongue can move away from or abut against the protrusion to lock or disengage the shoulder joint locking tube from the shoulder bone support member.

[0011] Furthermore, the wide-position locking tongue includes a hook member with a second limiting groove and a wide-position spring seat. One end of the wide-position spring seat is fixedly connected to the shoulder joint locking tube by a screw, and the other end is movably disposed in the second limiting groove of the hook member. When the hook member reciprocates relative to the wide-position spring seat, one end of the hook member engages with or moves away from the protrusion, and the end of the hook member away from the protrusion is exposed in the first limiting groove.

[0012] Furthermore, the shoulder joint locking tube includes a shoulder joint and a shoulder support tube movably inserted into the shoulder joint. The shoulder support tube has multiple first through holes on the side near the locking adjustment seat, and the shoulder joint has a second through hole on the side near the first through hole. The locking adjustment seat is detachably connected to the first through hole of the shoulder support tube by a nut passing through the second through hole. The end of the shoulder support tube away from the shoulder joint is connected to the hook stretcher component via a shoulder strap.

[0013] Furthermore, a third through hole is provided on the side of the shoulder joint near the shoulder bone support member, and the shoulder bone support member passes through the third through hole and is detachably connected to the shoulder joint member by screws.

[0014] Furthermore, the first spinal support connector is connected to the middle position of the shoulder support on the side away from the shoulder joint locking tube, and the end of the first spinal support connector away from the shoulder support is disposed in the second spinal support connector and is rotatably connected to the second spinal support connector through a spinal pin seat.

[0015] Furthermore, the spinal pin seat is disposed in the first groove of the first spinal support connector. The two side walls of the first spinal support connector have multiple sets of oppositely arranged openings. The spinal pin seat includes a connecting rod connected to a toggle member. One end of the connecting rod is connected to a crossbar. The toggle member and the crossbar are both movably disposed in the openings. A spinal spring seat is also connected in the first groove. The end of the connecting rod away from the crossbar passes through the spinal spring seat and can move relative to the spinal spring seat.

[0016] Furthermore, one end of the first spinal support connector is inserted into the second groove of the second spinal support connector, and the second spinal support connector has a third groove at one end near the spinal pin seat. The crossbar passes through the opening of the first spinal support connector and is engaged in the third groove. When the actuating member is moved, the crossbar can be moved away from the third groove, so that the first spinal support connector rotates relative to the second spinal support connector.

[0017] Furthermore, the second spinal support connector has a fourth groove on the side where the second groove is located. When the first spinal support connector rotates relative to the second spinal support connector, the crossbar moves away from the third groove and can be engaged in the fourth groove.

[0018] This invention provides a foldable stretcher-type exoskeleton device, including a shoulder bone support and a spine support connected to each other. The spine support includes a first spine support connector and a second spine support connector that are rotatably connected to each other. A shoulder joint locking tube is connected to each end of the shoulder bone support on the side away from the spine support. A hook stretcher component is connected to the end of the shoulder joint locking tube away from the shoulder bone support. A locking adjustment seat is connected to the end of the shoulder joint locking tube near the shoulder bone support. The shoulder joint locking tube is movably engaged with the shoulder bone support through the locking adjustment seat. The foldable stretcher-type exoskeleton device provided by this invention allows rescuers to wear the device and lift the stretcher using the hook stretcher component. When not in use, the spinal support component can be folded relative to each other through the relatively rotatable first and second spinal support connectors. The shoulder joint locking tubes at both ends of the shoulder support component can be quickly attached and detached from it through the locking adjustment seat. This allows the exoskeleton device to be folded multiple times when not in use, making it easy to store and fold. It is also convenient to fold and disassemble, and occupies little space.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that the descriptions involving "first," "second," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0029] Please refer to Figures 1 to 6 This invention provides a foldable stretcher-type exoskeleton device, including a shoulder bone support 1 and a spine support 2 connected to each other. The spine support 2 includes a first spine support connector 21 and a second spine support connector 22 that can be rotatably connected to each other. A shoulder joint locking tube 3 is connected to each end of the shoulder bone support 1 on the side away from the spine support 2. A hook stretcher component 34 is connected to the end of the shoulder joint locking tube 3 away from the shoulder bone support 1. A locking adjustment seat 4 is connected to the end of the shoulder joint locking tube 3 near the shoulder bone support 1. The shoulder joint locking tube 3 is movably engaged with the shoulder bone support 1 through the locking adjustment seat 4.

[0030] In this embodiment, the foldable stretcher-type exoskeleton device includes a shoulder support 1 and a spine support 2, which are connected to each other. The foldable stretcher-type exoskeleton device is worn on the human upper limb. The shoulder support 1 is adapted to the human shoulder, and the spine support 2 is adapted to the human spine, so that it can be adapted to the human upper limb.

[0031] In this embodiment, the spinal support 2 includes a first spinal support connector 21 and a second spinal support connector 22, which are movably connected. Specifically, the first spinal support connector 21 can be rotated relative to the second spinal support connector 22, allowing the first spinal support connector 21 and the second spinal support connector 22 to be folded in half, thus facilitating storage. When the foldable stretcher-type exoskeleton device needs to be used, to unfold the spinal support 2, simply rotate the first spinal support connector 21 and the second spinal support connector 22 relative to each other; that is, pull the first spinal support connector 21 and the second spinal support connector 22 in opposite directions respectively.

[0032] In this embodiment, a stretcher hook 34 is connected to the end of the shoulder joint locking tube 3 away from the shoulder bone support 1. Specifically, both shoulder joint locking tubes 3 on the device are equipped with stretcher hook 34s. The stretcher hook 34s are used to lift the stretcher without the need for rescuers to lift it by hand. Rescuers wear the foldable stretcher-lifting exoskeleton device on their bodies and then hook the stretcher with the stretcher hook 34s. This allows rescuers to play a highly efficient human assistance role in rescue situations when wearing the exoskeleton device and lifting the stretcher with the stretcher hook 34s, greatly reducing the physical exertion of rescuers, improving the efficiency of rescue work, and increasing continuous working time.

[0033] In this embodiment, a shoulder joint locking tube 3 is connected to each end of the shoulder bone support 1 on the side away from the spinal support 2. The shoulder joint locking tubes 3 at both ends of the shoulder bone support 1 are identical in shape and size. A locking adjustment seat 4 is connected to the end of the shoulder joint locking tube 3 closest to the shoulder bone support 1, and the shoulder joint locking tube 3 is movably engaged with the shoulder bone support 1 via the locking adjustment seat 4. Specifically, a locking adjustment seat 4 is provided on each of the shoulder joint locking tubes 3 at both ends of the shoulder bone support 1. The shoulder joint locking tube 3 is movably engaged with the shoulder bone support 1 via the locking adjustment seat 4, meaning that the locking adjustment seat 4 allows the shoulder bone support 1 and the shoulder joint locking tube 3 to be locked or disengaged. If it is necessary to disassemble the shoulder joint locking tubes 3 at both ends of the shoulder bone support 1, the engagement between the shoulder bone support 1 and the shoulder joint locking tube 3 is first released via the locking adjustment seat 4, allowing the shoulder bone support 1 and the shoulder joint locking tube 3 to be disassembled and separated for storage. When the foldable stretcher-type exoskeleton device is needed, the shoulder bone support 1 and the shoulder joint locking tubes 3 at both ends need to be unfolded. The shoulder joint locking tubes 3 can be snapped onto the two ends of the shoulder bone support 1 by means of the locking adjustment seat 4.

[0034] In this embodiment, the foldable stretcher exoskeleton device can be movably connected to the shoulder bone support 1 and the shoulder joint locking tubes 3 at both ends, and can be disassembled and assembled with the shoulder bone support 1 through the locking adjustment seat 4 on the shoulder joint locking tube 3. The spinal support 2 can also be folded at the same time, so that the foldable stretcher exoskeleton device can be folded multiple times and put into a storage bag for easy carrying and transportation.

[0035] Specifically, in this embodiment, the foldable stretcher-type exoskeleton device is made of aerospace-grade 7075 aluminum alloy, which is not only lightweight but also high-strength, simplifying the weight of the foldable stretcher-type exoskeleton device and making it more portable. Specifically, the shoulder bone support 1 is connected to one side of the shoulder joint locking tube 3, and a back plate is connected to the middle of that side to adapt to the human back; the end of the spinal support 2 away from the shoulder bone support 1 is connected to a hip plate to adapt to the human buttocks.

[0036] Furthermore, the locking seat 4 includes a locking housing 41 with a first limiting groove 42. A wide locking tongue 43 is movably connected in the first limiting groove 42. The wide locking tongue 43 can reciprocate relative to the locking housing 41 to lock or disengage the shoulder joint locking tube 3 from the shoulder bone support 1.

[0037] In this embodiment, the locking base 4 includes a locking housing 41, on which a first limiting groove 42 is provided. A wide locking tongue 43 is provided inside the locking housing 41, and the wide locking tongue 43 is movably disposed within the first limiting groove 42. Specifically, when the wide locking tongue 43 is slidably disposed within the first limiting groove 42, the wide locking tongue 43 also reciprocates relative to the locking housing 41, thereby allowing the shoulder joint locking tube 3 to lock or disengage relative to the shoulder bone support 1.

[0038] Specifically, the wide-position locking tongue 43 slides up and down within the first limiting groove 42 of the locking housing 41, sliding along the axial direction of the shoulder joint locking tube 3. When the wide-position locking tongue 43 slides up and down within the first limiting groove 42, it can lock or disengage the shoulder joint locking tube 3 connected to the locking seat 4 from the shoulder bone support 1. Specifically, when it is necessary to lock or disengage the shoulder joint locking tube 3 from the shoulder bone support 1, it is only necessary to slide the wide-position locking tongue 43, which is movably disposed within the first limiting groove 42, up and down to unlock or lock the shoulder joint locking tube 3 and the shoulder bone support 1.

[0039] Furthermore, the shoulder bone support 1 has a protrusion 11 on the side near the shoulder joint locking tube 3. The protrusion 11 engages with the wide locking tongue 43. When the wide locking tongue 43 moves relative to the locking housing 41, the wide locking tongue 43 can move away from or abut against the protrusion 11 so that the shoulder joint locking tube 3 is locked or disengaged from the shoulder bone support 1.

[0040] In this embodiment, the shoulder bone support 1 has a protrusion 11 on the side near the shoulder joint locking tube 3. Specifically, the shoulder bone support 1 has this protrusion 11 at both ends of the shoulder joint locking tube 3, and the protrusion 11 extends away from the shoulder bone support 1. The protrusion 11 is engaged with the wide locking tongue 43. When the wide locking tongue 43 moves relative to the locking housing 41, that is, when the wide locking tongue 43 moves relative to the first limiting groove 42 of the locking housing 41, the wide locking tongue 43 abuts against or moves away from the protrusion 11 on the shoulder bone support 1. When the wide locking tongue 43 abuts against the protrusion 11 on the shoulder bone support 1, the shoulder joint locking tube 3 locks the shoulder bone support 1 through the wide locking tongue 43, that is, the shoulder joint locking tube 3 is engaged with the shoulder bone support 1. When the wide locking tongue 43 moves relative to the first limiting groove 42, the wide locking tongue 43 moves away from the protrusion 11 on the shoulder bone support 1 during the movement, that is, the shoulder joint locking tube 3 is separated from the shoulder bone support 1 through the wide locking tongue 43, so that the shoulder joint locking tube 3 can be removed from the shoulder bone support 1.

[0041] Furthermore, the wide-position locking tongue 43 includes a hook 431 with a second limiting groove 432 and a wide-position spring seat 433. One end of the wide-position spring seat 433 is fixedly connected to the shoulder joint locking tube 3 by a screw, and the other end is movably disposed in the second limiting groove 432 of the hook 431. When the hook 431 reciprocates relative to the wide-position spring seat 433, one end of the hook 431 engages with or moves away from the protrusion 11, and the end of the hook 431 away from the protrusion 11 is exposed in the first limiting groove 42.

[0042] In this embodiment, the wide-position locking tongue 43 includes a hook member 431 and a wide-position spring seat 433. The hook member 431 is movably connected to the wide-position spring seat 433, and the hook member 431 is provided with a second limiting groove 432. The wide-position spring seat 433 is movably disposed within the second limiting groove 432 of the hook member 431. Specifically, one end of the wide-position spring seat 433 is fixedly connected to the shoulder joint locking tube 3 by a screw, and the end of the wide-position spring seat 433 away from the fixed connection with the shoulder joint locking tube 3 is movably disposed within the second limiting groove 432 of the hook member 431. When the hook member 431 reciprocates relative to the wide-position spring seat 433, that is, the hook member 431 repeatedly moves towards or away from the wide-position spring seat 433, one end of the hook member 431 can engage with or move away from the protrusion 11 of the shoulder bone support member 1. Specifically, when the hook 431 moves relative to the wide spring seat 433, and the hook 431 moves towards the direction closer to the wide spring seat 433, the end of the hook 431 away from the wide spring seat 433 moves away from the protrusion 11 on the shoulder bone support 1, thereby disengaging the shoulder joint locking tube 3 from the shoulder bone support 1, i.e., the shoulder joint locking tube 3 can be detached from the shoulder bone support 1. When it is necessary to prevent the shoulder joint locking tube 3 from being detached from the shoulder bone support 1, i.e., to engage the hook 431 with the protrusion 11 on the shoulder bone support 1, simply move the hook 431 towards the direction closer to the wide spring seat 433, and then release the hook 431. This will allow the wide spring seat 433 to reset and engage the hook 431 with the protrusion 11, thereby locking the shoulder joint locking tube 3 to the shoulder bone support 1. Furthermore, when the hook 431 reciprocates relative to the wide spring seat 433, the end of the hook 431 away from the protrusion 11 is exposed in the first limiting groove 42. The fact that one end of the hook 431 is exposed in the first limiting groove 42 makes it easier for the user to move the hook 431, thereby allowing the hook 431 to reciprocate relative to the wide spring seat 433.

[0043] Furthermore, the shoulder joint locking tube 3 includes a shoulder joint 31 and a shoulder support tube 32 movably inserted into the shoulder joint 31. The shoulder support tube 32 has multiple first through holes 321 on the side near the locking adjustment seat 4. The shoulder joint 31 has a second through hole 311 on the side near the first through hole 321. The locking adjustment seat 4 is detachably connected to the first through hole 321 of the shoulder support tube 32 by a nut passing through the second through hole 311. The end of the shoulder support tube 32 away from the shoulder joint 31 is connected to a hook stretcher component 34 via a shoulder strap 33.

[0044] In this embodiment, the shoulder joint locking tube 3 includes a shoulder joint 31 and a shoulder support tube 32. The shoulder support tube 32 is movably inserted into the shoulder joint 31, meaning the shoulder joint 31 is sleeved on the outside of the shoulder support tube 32. The shoulder support tube 32 has multiple first through holes 321 on the side near the locking adjustment seat 4, and the shoulder joint 31 has a second through hole 311 on the side near the first through hole 321. The locking adjustment seat 4 is detachably connected to the shoulder joint 31 and the shoulder support tube 32 by a nut passing through the second through hole 311 on the shoulder joint 31 and the first through hole 321 on the shoulder support tube 32. Specifically, the shoulder support tube 32 has multiple first through holes 321. The nut on the locking adjustment seat 4 can pass through the second through hole 311 on the shoulder joint 31 and can connect with multiple different first through holes 321 on the shoulder support tube 32, thereby adjusting the height of the shoulder support tube 32 within the shoulder joint 31. In this embodiment, there are four first through holes 321, allowing for four height adjustments within a range of 36mm, suitable for users with a height of 1.65-1.85m. If the user feels the shoulder support tube 32 is too low or too high, they can remove the nut connecting the first through hole 321 and the second through hole 311, adjust the shoulder support tube 32 to a suitable height, and then insert the nut back into the first through hole 321 on the shoulder support tube 32 to adjust it to the appropriate height range.

[0045] Specifically, the end of the shoulder support tube 32 away from the shoulder joint 31 is connected to the stretcher hook 34 via the shoulder strap 33, thereby enabling rescuers to better lift the stretcher via the stretcher hook 34. The exoskeleton device also provides efficient human assistance when lifting the stretcher, significantly reducing the physical exertion of rescuers, improving the efficiency of rescue work, and increasing continuous working time.

[0046] Furthermore, a third through hole is provided on the side of the shoulder joint component 31 near the shoulder bone support component 1, and the shoulder bone support component 1 passes through the third through hole and is detachably connected to the shoulder joint component 31 by screws.

[0047] In this embodiment, a third through hole (not shown in the figure) is provided on the side of the shoulder joint component 31 near the shoulder bone support component 1. The end of the shoulder bone support component 1 near the shoulder joint component 31 passes through the third through hole and is detachably connected to the shoulder joint component 31 by a screw. Both ends of the shoulder bone support component 1 are detachably connected to the shoulder joint component 31 through the third through hole, meaning that the shoulder bone support component 1 is detachably connected to the shoulder joint locking tube component 3 through its connection to the shoulder joint component 31.

[0048] In this embodiment, the shoulder bone support 1 is movably engaged with the shoulder joint locking tube 3 via the locking adjustment seat 4, thereby allowing the shoulder joint locking tube 3 to be detached from the shoulder bone support 1 or installed on the shoulder bone support 1. Specifically, before detaching the shoulder joint locking tube 3 from the shoulder bone support 1 via the locking adjustment seat 4, the screws connecting the shoulder bone support 1 and the shoulder joint 31 must be unscrewed before the shoulder bone support 1 and the shoulder joint locking tube 3 can be separated. After the shoulder joint locking tube 3 is installed on the shoulder bone support 1, the shoulder bone support 1 and the shoulder joint locking tube 3 are tightened with screws, thereby reinforcing the connection between the shoulder joint locking tube 3 and the shoulder bone support 1.

[0049] Furthermore, the first spinal support connector 21 is connected to the middle position of the shoulder support 1 on the side away from the shoulder joint locking tube 3, and the end of the first spinal support connector 21 away from the shoulder support 1 is disposed in the second spinal support connector 22 and is rotatably connected to the second spinal support connector 22 through a spinal pin seat 5.

[0050] In this embodiment, the spinal support 2 includes a first spinal support connector 21 and a second spinal support connector 22 that are rotatably connected. The spinal support 2 is connected to the side of the shoulder support 1 away from the shoulder joint locking tube 3. Specifically, the first spinal support connector 21 is connected to the middle position of the side of the shoulder support 1 away from the shoulder joint locking tube 3, that is, the first spinal support connector 21 is located at the midpoint of the shoulder support 1. The end of the first spinal support connector 21 away from the shoulder support 1 is connected and disposed within the second spinal support connector 22, and the first spinal support connector 21 is rotatably connected to the second spinal support connector 22 through a spinal pin seat 5. The rotatable connection between the first spinal support connector 21 and the second spinal support connector 22 via the spinal pin seat 5 allows the spinal support 2 to be folded in half, thus making the foldable stretcher-type exoskeleton device easy to fold and store.

[0051] Furthermore, the spinal pin seat 5 is disposed in the first groove 211 of the first spinal support connector 21. The two side walls of the first spinal support connector 21 have multiple sets of oppositely arranged openings. The spinal pin seat 5 includes a connecting rod 51 connected to a toggle member 52. One end of the connecting rod 51 is connected to a crossbar 53. The toggle member 52 and the crossbar 53 are both movably disposed in the openings. A spinal spring seat 54 is also connected in the first groove 211. The end of the connecting rod 51 away from the crossbar 53 passes through the spinal spring seat 54 and can move relative to the spinal spring seat 54.

[0052] In this embodiment, the first spinal support connector 21 has a first groove 211, and the spinal pin seat 5 is disposed in the first groove 211 of the first spinal support connector 21. The two side walls of the first groove 211 of the first spinal support connector 21 have multiple sets of oppositely arranged openings. Specifically, the spinal pin seat 5 includes a connecting rod 51, a toggle member 52 is connected to the connecting rod 51, and a crossbar 53 is disposed at one end of the connecting rod 51 near the second spinal support connector 22. The toggle member 52 and the crossbar 53 connected to the connecting rod 51 are both movably disposed in the oppositely arranged openings on the two side walls of the first groove 211. That is, the toggle member 52 is movably disposed in the first groove 211, and the two sides of the toggle member 52 are movably connected to a set of oppositely arranged openings; the crossbar 53 is also movably disposed in the first groove 211, and the two sides of the crossbar 53 are movably connected to another set of oppositely arranged openings. A spinal spring seat 54 is also connected within the first groove 211 of the first spinal support connector 21. The spinal spring seat 54 is fixedly disposed within the first groove 211, and a through hole is provided on the spinal spring seat 54. The end of the connecting rod 51 away from the crossbar 53 passes through the through hole provided on the spinal spring seat 54 and moves relative to the spinal spring seat 54. The surface of the actuating component 52 is provided with anti-slip texture, which increases the friction between the user and the actuating component 52 when the user actuates the actuating component 52.

[0053] Furthermore, one end of the first spinal support connector 21 is inserted into the second groove 221 of the second spinal support connector 22. The second spinal support connector 22 has a third groove 222 at one end near the spinal pin seat 5. The crossbar 53 passes through the opening of the first spinal support connector 21 and is engaged in the third groove 222. When the actuating member 52 is moved, the crossbar 53 can be moved away from the third groove 222, so that the first spinal support connector 21 rotates relative to the second spinal support connector 22.

[0054] In this embodiment, one end of the first spinal support connector 21 is disposed within the second spinal support connector 22. Specifically, the second spinal support connector 22 has a second groove 221, and the first spinal support connector 21 is inserted into the second groove 221 of the second spinal support connector 22. The second spinal support connector 22 has a third groove 222 at one end near the spinal pin seat 5, that is, the second spinal support connector 22 has a third groove 222 near the top end of the first spinal support connector 21. The crossbar 53 passes through the openings on both sides of the first spinal support connector 21 and is engaged in the third groove 222. When the user moves the actuating member 52 up and down, the actuating member 52 can drive the crossbar away from the third groove 222, and the first spinal support connector 21 can rotate relative to the second spinal support connector 22, thereby folding the first spinal support connector 21 and the second spinal support connector 22 together.

[0055] In this embodiment, when the first spinal support connector 21 and the second spinal support connector 22 need to be folded in half, simply move the actuating member 52 away from the second spinal support connector 22. The actuating member 52 moves in the opening away from the second spinal support connector 22, and drives the crossbar 53 to move in the opening away from the second spinal support connector 22, and disengage from the third groove 222. Then release the actuating member 52, so that the first spinal support connector 21 and the second spinal support connector 22 can rotate relative to each other and be folded in half. When it is necessary to unfold the first spinal support connector 21 and the second spinal support connector 22, simply move the actuating member 52 toward the spinal spring seat 54. The actuating member 52 moves away from the second spinal support connector 22 within the opening, and drives the crossbar 53 to move away from the second spinal support connector 22. Then rotate the first spinal support connector 21, release the actuating member 52 so that the spinal spring seat 54 resets and drives the crossbar 53 to move toward the second spinal support connector 22 until the crossbar 53 enters the third groove 222 of the second spinal support connector 22. Then the first spinal support connector 21 and the second spinal support connector 22 can be unfolded and set up.

[0056] Furthermore, the second spinal support connector 22 has a fourth groove 223 on the side where the second groove 221 is provided. When the first spinal support connector 21 rotates relative to the second spinal support connector 22, the crossbar 53 moves away from the third groove 222 and can be locked in the fourth groove 223.

[0057] In this embodiment, the second spinal support connector 22 has a fourth groove 223 on one side where the second groove 221 is provided. When the first spinal support connector 21 rotates relative to the second spinal support connector 22, that is, when the first spinal support connector 21 is folded relative to the second spinal support connector 22, the crossbar 53 disengages from the third groove 222 of the second spinal support connector 22 and then moves towards the second spinal support connector 22. The second spinal support connector 22 also has a fourth groove 223. When the crossbar 53 moves towards the second spinal support connector 22, it can be locked in the fourth groove 223, which makes the folding of the first spinal support connector 21 and the second spinal support connector 22 more stable, and the first spinal support connector 21 and the second spinal support connector 22 will not disengage after being folded relative to each other.

[0058] This invention provides a foldable stretcher-type exoskeleton device, including a shoulder bone support and a spine support connected to each other. The spine support includes a first spine support connector and a second spine support connector that are rotatably connected to each other. A shoulder joint locking tube is connected to each end of the shoulder bone support on the side away from the spine support. A hook stretcher component is connected to the end of the shoulder joint locking tube away from the shoulder bone support. A locking adjustment seat is connected to the end of the shoulder joint locking tube near the shoulder bone support. The shoulder joint locking tube is movably engaged with the shoulder bone support through the locking adjustment seat. The foldable stretcher-type exoskeleton device provided by this invention allows rescuers to wear the device and lift the stretcher using the hook stretcher component. When not in use, the spinal support component can be folded relative to each other through the relatively rotatable first and second spinal support connectors. The shoulder joint locking tubes at both ends of the shoulder support component can be quickly attached and detached from it through the locking adjustment seat. This allows the exoskeleton device to be folded multiple times when not in use, making it easy to store and fold. It is also convenient to fold and disassemble, and occupies little space.
