[0002] At present, exoskeleton wearable devices have a wide range of applications. For example, they can be used for medical rehabilitation to help patients with rehabilitation training, and they can also be worn on the human body for assistance. Therefore, in order to meet the wearing and use needs of people of different heights and body shapes, exoskeletons generally need to have adjustment functions. Among them, the exoskeleton width adjustment function is to meet the use needs of wearers with different waist circumferences. Since the waist is the main load-bearing part of the exoskeleton, high requirements are placed on the stability and reliability of the adjustment mechanism. The existing width adjustment mostly adopts the form of screw connection, and a few adjustment mechanisms adopt the form of pins. Although the screw connection is reliable, the adjustment time is long and requires the assistance of tools, which does not meet the convenience requirements; the adjustment mechanism in the form of a pin needs to drill adjustment holes on the original structural parts, which destroys the strength of the structural parts and cannot be locked, resulting in gaps and shaking between the connecting parts, affecting the force transmission effect. Neither of the above two adjustment methods supports stepless adjustment. Summary of the invention

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] like Figure 1 As shown, an embodiment of the present application provides an exoskeleton width adjustment locking device, including: an adjustment locking assembly 1, a connection base 2, a first connection member 3-1 and a second connection member 3-2, the adjustment locking assembly 1 is arranged at both ends of the connection base 2, and the adjustment locking assembly 1 is movably connected to the first connection member 3-1 and the second connection member 3-2 respectively, the adjustment locking assembly 1 includes a clamping unit and a locking unit, the clamping unit is movably arranged on both ends of the connection base 2 to form a first clamping space and a second clamping space, the first connection member 3-1 is arranged in the first clamping space, the second connection member 3-2 is arranged in the second clamping space, and the tail of the locking unit is rotatably arranged on the clamping unit The first connector 3-1 and the second connector 3-2 are respectively arranged on one end of the member, and when the head of the locking unit is locked on the connecting base 2, the clamping unit holds the first connector 3-1 and the second connector 3-2 tightly. When the head of the locking unit is away from the connecting base 2, one end of the clamping unit rotates to increase the first clamping space and the second clamping space so as to adjust the distance between the first connector 3-1 and the second connector 3-2, thereby shortening the time for adjusting the width of the exoskeleton and improving the convenience of adjustment. The locking unit can also be used to lock the first connector 3-1 and the second connector 3-2, thereby avoiding gaps and shaking between the first connector 3-1 and the second connector 3-2 and the connecting base 2, thereby preventing the transmission of force.

[0025] In one embodiment, the clamping unit includes a first clamping sleeve 1-2 and a first rotating module. One end of the first clamping sleeve 1-2 is disposed on an edge area of the connection base 2, and the first rotating module is disposed on another edge area of the connection base 2. The other end of the first clamping sleeve 1-2 is rotatably connected to the first rotating member. The locking unit is rotatably disposed on an edge area of the connection base 2 and above the first clamping sleeve 1-2 to press and lock the first clamping sleeve 1-2 or unlock the first clamping sleeve 1-2. When the locking unit clamps, unlocks, and loosens the first clamping sleeve 1-2, the other end of the first clamping sleeve 1-2 rotates on the first rotating member, so that the first clamping sleeve 1-2 will loosen the first connecting member 3-1 to facilitate adjusting the distance between the first connecting member 3-1 and the connection base 2, thereby realizing the width adjustment of the exoskeleton.

[0026] In one embodiment, the first rotating module includes a fixing member 1-10 and a rotating shaft 1-12. The fixing member 1-10 is disposed on another edge area of the connection base 2. One end of the first clamping sleeve 1-2 is sleeved on the rotating shaft 1-12, and the rotating shaft 1-12 is disposed on the fixing member 1-10. Through the fixing member 1-10 and the rotating shaft 1-12, when the locking unit clamps, unlocks, and loosens the first clamping sleeve 1-2, the other end of the first clamping sleeve 1-2 rotates on the first rotating member, which is more conducive to adjusting the distance between the first connecting member 3-1 or the second connecting member 3-2 and the connection base 2.

[0027] In one embodiment, the clamping unit further includes an elastic washer 1-3. The elastic washer 1-3 is detachably disposed in the first clamping sleeve 1-2. By providing the elastic washer 1-3, it is convenient for the locking unit to lock or unlock the first connecting member 3-1 or the second connecting member 3-2, improving the adjustment efficiency.

[0028] In one embodiment, the clamping unit further includes a guide shaft 1-4 and a metal washer 1-5. The guide shaft 1-4 is disposed on an edge area of the connection base 2, passes through one end of the first clamping sleeve 1-2 and is sleeved in the metal washer 1-5, and the top end of the guide shaft 1-4 is rotatably connected to the locking unit. The locking unit is fixed above the first clamping sleeve 1-2 through the guide shaft 1-4, so that when the locking unit unlocks, the locking unit rotates away from the connection base 2, and at the same time, it is convenient for the locking unit to lock and approach the connection base 2 to lock the clamping unit. In addition, the clamping unit further includes a camshaft 1-6. The camshaft 1-6 is disposed on the guide shaft 1-4, and the camshaft 1-6 is rotatably connected to the locking unit.

[0029] In one embodiment, the locking unit includes a cam handle 1-1 and a locking tongue 1-7. The locking tongue 1-7 is arranged on the connecting base 2. The tail of the cam handle 1-1 is rotatably arranged at one end of the clamping unit, and the head of the cam handle 1-1 cooperates with the locking tongue 1-7 to lock the clamping unit. Through the cam handle 1-1 and the locking tongue 1-7, the locking and unlocking of the clamping unit are realized. Using one cam handle 1-1 to achieve locking at both ends is beneficial to quickly adjust the width of the exoskeleton and is applicable to the vast majority of exoskeleton structures.

[0030] In one embodiment, the locking unit further includes a locking tongue bracket 1-9 and a torsion spring 1-8. The locking tongue bracket 1-9 is arranged on the connecting base 2. The torsion spring 1-8 is rotatably arranged on the locking tongue bracket 1-9, and the locking tongue 1-7 is arranged on the torsion spring 1-8. Through the locking tongue bracket 1-9 and the torsion spring 1-8, the locking tongue 1-7 maintains a certain torsional tension in the locking tongue bracket 1-9. In the locked and closed state, the locking tongue 1-7 passes through the cam handle 1-1, and the cam handle 1-1 is clamped by the tension provided by the torsion spring 1-8 to achieve locking. That is, after the adjustment is completed, the cam handle 1-1 is pulled inward by about 90 degrees, so that it slides over the inclined surface of the locking tongue 1-7 and is clamped by the locking tongue 1-7. Then, the locking tongue 1-7 is pushed upward, and then the cam handle 1-1 is pulled outward by about 90 degrees to achieve unlocking, that is, the locking tongue 1-7 is separated from the cam handle 1-1.

[0031] In one embodiment, the first connecting member 3-1 and the second connecting member 3-2 are symmetric about the central axis of the adjusting and locking assembly 1. By setting the symmetric structure, the structure is simplified and the production cost is saved.

[0032] This application also provides an exoskeleton wearable device, including the exoskeleton width adjusting and locking device described in any one of the above. The exoskeleton wearable device is provided with a width adjusting and locking device, which can prevent potential safety hazards caused by loosening of the connecting members due to long-term use of the exoskeleton, accidental collision, etc.
