Description

Technical Field

[0001] This utility model relates to the field of exoskeleton assistive device technology, and in particular to a lower limb exoskeleton assistive device with fall protection. Background Technology

[0002] The lower limb exoskeleton assistive device is a wearable exoskeleton device that can assist people in walking. It combines the mechanical energy of an external mechanical power unit with intelligence, which can reduce the stress on the legs and provide additional power. The lower limb exoskeleton assistive device is easy to wear and use through straps.

[0003] Currently, existing lower limb exoskeleton assistive devices are used by attaching adjustable straps to the user's waist, and then straps to the legs. During walking, the power unit pulls on the rods, which in turn pulls the leg straps to provide lifting assistance. However, in order to ensure portability, most of these existing lower limb exoskeleton assistive devices lack fall protection for the user and require further optimization.

[0004] Therefore, this application provides a fall-protective lower limb exoskeleton assistive device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lower limb exoskeleton assistive device with fall protection in order to solve the problem that most existing lower limb exoskeleton assistive devices lack fall protection for users in order to ensure portability.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A fall-protective lower limb exoskeleton assistive device includes a waist wearing ring for wearing on the user's waist, mounting plates are symmetrically fixed on both sides of the waist wearing ring, a housing is fixed to the outer side of the mounting plates, a power component is provided inside the housing, and a lower limb pull rod extending out of the bottom of the housing is connected to it, and a leg strap mechanism is provided at the lower end of the lower limb pull rod.

[0008] The leg strap mechanism includes a reference block, which is fixed to the lower end of the lower limb pull rod. A second strap for binding to the user's thigh is provided on one side of the reference block. Connecting straps are installed on both sides of the second strap. A third strap for binding to the user's knee is installed at the lower end of the two connecting straps. A knee guard is fixed on the third strap. An abutment ring for abutting against the user's kneecap is elastically installed inside the knee guard.

[0009] Optionally, a control unit is installed in the middle of one side of the waist wearing ring, and a first strap is installed on the other side of the waist wearing ring.

[0010] Optionally, a movable shell is inserted and installed in the middle of the housing, the movable shell completely covering the power components inside the housing, and a plurality of first springs are connected to the edge of the movable shell inserted into the housing.

[0011] Optionally, the bottom of the housing has an output port for the power assembly to extend out, and the movable shell has a connection port at the position corresponding to the output port.

[0012] Optionally, the knee guard has a ventilation opening at the bottom.

[0013] Optionally, a perforated plate is snapped into the knee guard, a second spring is fixed in the middle of the perforated plate, and the abutment ring is connected to the abutment ring and drives the abutment ring to abut against the outer periphery of the user's kneecap.

[0014] Optionally, the abutment ring is made of a soft material.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the design of the knee shield and the abutment ring, the knee shield can cover the user's kneecap, and the abutment ring can provide elastic support. When the user falls and the knee is hit, the elastic support of the abutment ring can buffer the impact and protect the user's knee.

[0017] In the above solution, thanks to the cooperation between the housing and the movable shell, when the user falls and hits the ground from the side, the movable shell can elastically expand and contract within the housing to provide a cushioning effect and dissipate the force. Furthermore, since the movable shell completely covers the power components inside the housing, it can provide a certain degree of protection for the device and help extend its service life.

[0018] In summary, this device not only protects the user's knees and prevents falls, but also protects the power components inside the device, resulting in excellent overall performance. Attached Figure Description

[0035] Cooperate Figure 4 As shown, a knee protector 8 is fixed to the third strap 704, and an abutment ring 804 for abutting against the user's kneecap is elastically installed inside the knee protector 8. The knee protector 8 has a vent 801 at its bottom end for ventilation, and a perforated plate 802 is snapped into the inside of the knee protector 8. A second spring 803 is fixed in the middle of the perforated plate 802, and the abutment ring 804 is connected to and driven to abut against the outer edge of the user's kneecap. In specific implementations, the abutment ring 804 is made of a soft material, such as a rubber ring.

[0036] The working principle of this utility model is as follows: In use, the lower limb exoskeleton assistive device for fall protection can be worn with the waist ring 1 around the waist, and the second strap 702 and third strap 704 worn on the thigh and knee respectively. Therefore, during use, if the user falls, the knee protector 8 can provide initial protection for the user's knees, and the second spring 803 and the abutment ring 804 inside provide cushioning, reducing the impact force on the kneecap and achieving a fall protection effect.

[0037] In addition, if the user falls and hits the ground from the side, the movable shell 501 can elastically extend and retract within the housing 5 to provide a cushioning effect and dissipate the force. Furthermore, since the movable shell 501 completely covers the power components inside the housing 5, it can provide a certain degree of protection for the device and help extend its service life.

[0038] In summary, this device not only protects the user's knees and prevents falls, but also protects the power components inside the device, resulting in excellent overall performance.
