Description

Technical Field

[0001] This utility model relates to the field of exoskeleton equipment technology, specifically an exoskeleton equipment with adjustable torso frame height. Background Technology

[0002] An exoskeleton is a wearable mechanical device, usually made of materials such as metal and plastic, that is connected to the human body through a mechanical structure. It can mimic the way the human body moves and provide the human body with additional strength, endurance and stability.

[0003] For example, an existing patent (publication number: CN115488857A) discloses an exoskeleton device, including: a back unit and a waist unit, a thigh unit and a calf unit, the length of the back unit, thigh unit and calf unit are adaptively adjusted according to the current wearer's back length, thigh length and calf length, so as to meet the wearing needs of wearers of different heights.

[0004] However, the exoskeleton equipment designed above still has some drawbacks in actual use: the exoskeleton equipment lacks support and fit for the human waist, and cannot dynamically adjust its position and shape to follow the movement of the human waist, which makes the waist bear greater pressure during the movement, easily causing fatigue and injury, and long-term use may also have adverse effects on waist health.

[0005] To address these issues, we designed an adjustable torso frame exoskeleton. Utility Model Content

[0006] The purpose of this invention is to provide an exoskeleton device with adjustable torso frame height to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides an adjustable torso frame height exoskeleton equipment, including a shoulder strap, a connecting plate connected to one end of the shoulder strap, a height adjustment component installed at the bottom end of the connecting plate, an inner shaft rotatably connected to the bottom of the height adjustment component, an adaptive joint sleeved on the outer side of the inner shaft, the adaptive joints being spaced apart on the inner shaft, a ball joint fixedly connected to the bottom end of the adaptive joint, a waist support rotatably connected to the movable end of the ball joint, connecting tubes fixedly connected to both sides of the ball joint, a waist belt fixedly connected to the end of the connecting tube away from the ball joint, and a waist belt fixedly connected to the end of the shoulder strap away from the connecting plate.

[0008] Furthermore, a memory spring is fixedly connected between adjacent adaptive joints.

[0009] Furthermore, the lumbar support is made of memory foam.

[0010] Furthermore, the height adjustment component includes a mounting plate, which is rotatably connected to the bottom of the connecting plate. A latch is rotatably connected to the inner side of the mounting plate. A movable plate is slidably connected to the sliding groove of the mounting plate. A slot is provided on the movable plate. A locking block is fixedly connected to one end of the latch, and the locking block engages with the slot.

[0011] Furthermore, the bottom ends of the connecting pipe are rotatably connected to symmetrically arranged connecting rods, and protective shells are installed on the opposite bottom ends of the two connecting rods. Elastic bands are fixedly connected to the opposite sides of the two protective shells.

[0012] Furthermore, the memory spring is made of nickel-titanium alloy.

[0013] Furthermore, a rotating shaft is mounted on the mounting plate, and a torsion spring is sleeved on the outside of the rotating shaft. The latch is rotatably connected to the mounting plate via the rotating shaft.

[0014] Furthermore, an inclined block is obliquely connected to the outer side of the latch.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting an adaptive joint on the inner axis to fit the back, the position changes with the rotation of the back. The lumbar support is adjusted to fit the human waist through the ball joint seat. The lumbar support is made of memory foam material, which can deform according to the curve of the human waist, distribute the pressure on the waist, and reduce the risk of waist fatigue and injury. During use, the connecting tube deforms with the position of the ball joint seat to maintain the stability of the overall structure of the equipment, so that the equipment works together when the human body moves, improves reliability and practicality, and provides auxiliary support.

[0017] 2. By pressing the tilt block, the plate can be linearly slid along the groove of the mounting plate to adjust the distance between them. After releasing, the latch will automatically rotate under the action of the torsion spring, and the locking block will be embedded into the corresponding slot. This allows you to adjust the distance between the connecting plate and the inner shaft according to your own needs, adapt to different heights, make the equipment fit the body, and improve wearing comfort and applicability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: an adjustable torso frame height exoskeleton, including a shoulder strap 1, a connecting plate 2 connected to one end of the shoulder strap 1, a height adjustment component installed at the bottom of the connecting plate 2, an inner shaft 19 rotatably connected to the bottom of the height adjustment component, an adaptive joint 4 sleeved on the outer side of the inner shaft 19, the adaptive joints 4 being spaced apart on the inner shaft 19, a ball joint seat 10 fixedly connected to the bottom of the adaptive joint 4, a waist support 3 rotatably connected to the movable end of the ball joint seat 10, a ball head installed on one side of the waist support 3 being embedded in the ball socket of the ball joint seat 10, the waist support 3 being able to rotate flexibly with the movement of the waist during use, always maintaining a good fit with the waist, the waist support 3 being made of memory foam material, which can deform according to the curve of the human waist and distribute local pressure, connecting tubes 9 fixedly connected to both sides of the ball joint seat 10, a waist belt 6 fixedly connected to the end of the connecting tube 9 away from the ball joint seat 10, and the end of the shoulder strap 1 away from the connecting plate 2 being fixedly connected to the waist belt 6.

[0026] In practice, first put the back strap 1 on your back and tie the waist belt 6 around your waist. Adjust the height component according to your needs to adjust the distance between the connecting plate 2 and the inner shaft 19. The adaptive joint 4 on the inner shaft 19 fits the back and changes position as the back rotates. The adaptive joint 4 drives the waist support 3 to adjust its position through the ball joint seat 10, so that the waist support 3 fits the waist of the human body. Because the waist support 3 is made of memory foam, it can deform according to the curve of the human waist and distribute local pressure. In the whole process, the connecting tube 9 undergoes a certain deformation as the position of the ball joint seat 10 changes to maintain the stability of the overall structure.

[0027] See Figures 3-4The height adjustment component includes a mounting plate 11, which is rotatably connected to the bottom of a connecting plate 2. A latch 13 is rotatably connected to the inner side of the mounting plate 11, and an inclined block 14 is inclinedly connected to the outer side of the latch 13. A movable plate 12 is slidably connected to the slide groove of the mounting plate 11. The height of the torso frame can be changed by adjusting the position of the movable plate 12. A slot 15 is provided on the movable plate 12. A locking block 16 is fixedly connected to one end of the latch 13. The locking block 16 engages with the slot 15. A rotating shaft 17 is mounted on the mounting plate 11. A torsion spring 18 is sleeved on the outer side of the rotating shaft 17. The latch 13 is rotatably connected to the mounting plate 11 through the rotating shaft 17. When force is applied manually, the latch 13 rotates around the rotating shaft 17, compressing the elastic force generated by the torsion spring 18, which causes the locking block 16 to disengage from the slot 15 of the movable plate 12. At this time, the tilting block 14 is disengaged from the moving plate 12. When in use, press the tilting block 14, and the locking block 16 will no longer be engaged with the moving plate 12. The moving plate 12 will slide linearly along the slide groove of the mounting plate 11 to the appropriate position, and then be released. The locking buckle 13 will rotate automatically under the elastic force of the torsion spring 18, and the locking block 16 will be embedded in the corresponding slot 15 to lock the moving plate 12.

[0028] See Figures 1-5 A memory spring 20 is fixedly connected between adjacent adaptive joints 4. The memory spring 20 is made of nickel-titanium alloy and compensates for the dynamic displacement during human movement through its own deformation. The bottom ends of the connecting tube 9 are rotatably connected to symmetrically arranged connecting rods 5. Protective shells 7 are installed on the opposite bottom ends of the two connecting rods 5. Elastic bands 8 are fixedly connected to the opposite sides of the two protective shells 7. The elastic bands 8 are made of rubber composite fiber material and adapt to the thigh circumference of different wearers through elastic deformation when worn. Its two ends are fixed to the inner lugs of the protective shells 7 by rivets to form an elastic constraint structure around the outside of the thigh.

[0029] Working principle:

[0030] First, put on the exoskeleton equipment, put the back strap 1 on your back, fasten the waist belt 6 around your waist, and wrap the elastic band 8 around the outside of your thighs. The elastic band 8 is made of rubber composite fiber material and can adapt to the thigh circumference of different wearers through elastic deformation. Then, operate the height adjustment component according to your own needs, press the tilt block 14 to make the locking block 16 disengage from the slot 15 of the moving plate 12, slide the moving plate 12 linearly along the slide groove of the mounting plate 11, adjust the distance between the connecting plate 2 and the inner shaft 19, and after releasing, the buckle 13 will automatically rotate under the elastic force of the torsion spring 18, and the locking block 16 will be inserted into the corresponding slot 15 to complete the height adjustment.

[0031] The adaptive joint 4 on the inner shaft 19 fits the back and changes position as the back rotates. The lumbar support 3 is adjusted to fit the waist of the human body through the ball joint seat 10. The lumbar support 3 is made of memory foam material, which can deform according to the curve of the human waist and distribute local pressure. The memory spring 20 between adjacent adaptive joints 4 compensates for the dynamic displacement during human movement through its own deformation.
