Description

Technical Field

[0001] The utility model relates to the technical field of exoskeletons, in particular to a leg belt and an exoskeleton device. Background Art

[0002] Currently, existing exoskeleton leg straps are usually made of a single elastic material, such as elastic textile fabric. However, due to individual differences in leg shape, especially the large variation in the taper of the back of the thigh, a single piece of elastic material is difficult to cut to fit different leg tapers.

[0003] To this end, most existing solutions use one or more relatively short strips of material that fit the legs to meet the compatibility of the thigh dimensions. However, this type of leg strap structure reduces the force-bearing area, and is prone to deformation and relative position slippage due to the weight or volume of the legs during the exoskeleton. In addition, in order to ensure stability during exercise, it is common to overstretch the leg strap to apply initial pressure during wearing. Long-term use will put too much pressure on the posterior thigh muscles, which can easily make the user feel uncomfortable. Utility Model Content

[0004] The purpose of the utility model is to provide an exoskeleton leg band that can provide a stable covering feeling to the thigh and ensure the comfort of the user after the user wears it.

[0005] In order to achieve the above-mentioned purpose, the first aspect of the utility model provides a leg strap, which is applied to an exoskeleton device, including a front leg strap body and a rear leg strap body, the front leg strap body is used to cover the front side of the thigh, and the rear leg strap body is used to cover the back side of the thigh, one end of the front leg strap body and one end of the rear leg strap body are connected to a first adjustment part, the other end of the front leg strap body and the other end of the rear leg strap body are connected to a second adjustment part, the rear leg strap body is made of elastic material, and an anti-deformation component is provided on the rear leg strap body.

[0006] Based on the above technical solution, one end of the front leg strap and one end of the rear leg strap are connected with the first adjustment part, and the other end of the front leg strap and the other end of the rear leg strap are connected with the second adjustment part. The leg strap can be adjusted from both sides of the thigh to adapt to different leg shapes, ensuring that the front leg strap is wrapped around the quadriceps femoris and the rear leg strap is wrapped around the biceps femoris, and the fitting position is accurate; the anti-deformation component is arranged on the rear leg strap to ensure that when the rear leg strap applies elastic force to wrap around the back of the thigh, the width deformation of the rear leg strap is reduced, the fitting area between the rear leg strap and the back of the thigh is maintained, and excessive pressure is prevented, which causes discomfort during user use.

[0007] Furthermore, the rear leg belt body includes a first pad layer and a second pad layer sewn together, the first pad layer and the second pad layer jointly define a receiving cavity, and the anti-deformation component is arranged in the receiving cavity. The anti-deformation component is arranged in the receiving cavity, which can ensure the anti-deformation effect when the rear leg belt body covers the back of the thigh when the user uses it, and can also prevent the hard feeling of the anti-deformation component from causing discomfort to the user.

[0008] Furthermore, the anti-deformation component includes a first anti-deformation sheet and a second anti-deformation sheet, the first anti-deformation sheet and the second anti-deformation sheet are both arranged in the accommodating cavity, the first anti-deformation sheet is located at one end of the accommodating cavity, and the second anti-deformation sheet is located at the other end of the accommodating cavity. The first anti-deformation sheet and the second anti-deformation sheet are both accommodated in the accommodating cavity.
