Description

Technical Field

[0001] The utility model relates to the technical field of protective gear, in particular to a carbon fiber leg protective gear. Background Art

[0002] During exercise, such as walking and running, the legs need to flex and extend the knees repeatedly, and the core part of the flexion and extension is the knee joint. The impact force generated by the foot contacting the ground will act in the opposite direction on the knee joint, so the legs need to wear protective structures to prevent damage to the knee joint.

[0003] Prior to this, we proposed a carbon fiber leg fixation device (CN218652170U). In the technical solution of this device, on the one hand, it can provide stable support for the legs, and on the other hand, it can constrain the angles of knee flexion and extension, thereby protecting the knee joint. However, this device still has some shortcomings. For example, the force required during knee extension comes entirely from the user's own force, and the device has limited ability to weaken impact force. Based on this, we re-propose a carbon fiber leg protector, which can not only assist in knee extension reduction, but also achieve buffering, thereby further protecting the knee joint.

Figure 7 , 8 As shown in the figure, the first brace 1 and the second brace 2 can rotate relative to each other at the position of the joint component 3, and the supporting and buffering component 4 can adaptively adjust the length following the relative rotation of the first brace 1 and the second brace 2. The supporting and buffering component 4 adopts a gas spring which can not only provide leg support and provide a resetting force when the knee is extended, but also provide a buffer to avoid damage to the knee joint.

[0031] First, the first brace 1 and the second brace 2 are both equipped with a plurality of straps (the straps are not shown in the figure). In order to facilitate the assembly of the straps, a plurality of mounting holes 11 are reserved on the surface of the first brace 1 and the second brace 2.
