[0019] Example 1

[0020] like Figures 1-3 As shown in the figure, the knee brace structure proposed in this embodiment includes a knee brace body 1 and multiple sets of anti-fall components.

[0021] The knee brace body 1 is made of nylon, spandex, or polyester limiting material; binding components are installed at both the upper and lower ends of the knee brace body 1; the anti-fall component includes a connecting rope 7, a guide rail 8, an elastic metal sheet 9, a wedge block 10, a push plate 11, a movable column 12, a first spring 13, a connecting slider 14, a guide rod 15, a second spring 16, a fixing pin 17, a movable plate 18, a fixing seat 41, and a sleeve 42. The fixing seat 41 is connected to the knee brace body 1 via the connecting rope 7. The guide rail 8 is connected to the side of the fixing seat 41, and a groove is provided on the guide rail 8. The guide rod 15 is located within the groove, and the second spring 16 is sleeved on it. Mounted on guide rod 15, connecting slider 14 is slidably mounted on guide rod 15 and connected to sleeve 42, movable plate 18 is movably mounted on the inner side of sleeve 42, fixed pin 17 is connected to movable plate 18, fixed seat 41 has a pin hole 411 that matches fixed pin 17, movable column 12 movably passes through the inner and outer sides of sleeve 42, movable plate 18 and push plate 11 are respectively connected to the two ends of movable column 12, first spring 13 is sleeved and mounted on movable column 12, the spring coefficient of second spring 16 is less than the spring coefficient of first spring 13, wedge block 10 is connected to the outer end of guide rail 8 through elastic metal sheet 9.

[0022] Specifically, the knee brace body 1 is placed at the knee and secured with two sets of binding components, which are respectively tied to the thigh and calf. Then, the anti-fall component is fixed to the pants, and the flat portion of the pants at the knee is folded into wrinkles, positioning the wrinkled portion between the fixing seat 41 and the sleeve 42. The push plate 11 is then pressed down, causing the sleeve 42 to move. Because the second spring 16 has a lower stiffness coefficient, it deforms more easily, while the first spring 13 has a smaller deformation. After the sleeve 42 is pressed firmly onto the pants, the fixing pin 17 remains inside the sleeve 42, continuously driving the push plate 1. 1. Move downwards until the fixing needle 17 passes through the fold of the pants and is placed inside the needle hole 411. Through the above structure, the fixing needle 17 will not be exposed before fixing, which improves the safety of operation. And when fixing, only pressing down is required, which is simple to operate. When the push plate 11 contacts the inclined surface of the wedge block 10, it forces the wedge block 10 to shift to one side, causing the elastic metal sheet 9 to deform. The elastic metal sheet 9 is made of a material with good toughness. When the push plate 11 moves to the limited position, the wedge block 10 is located at the upper end of the push plate 11. The elastic metal sheet 9 drives the wedge block 10 to quickly reset and limit the push plate 11.

[0023] Example 2

[0024] like Figure 1 As shown in the figure, the knee brace structure proposed in this embodiment, compared with the first embodiment, has an electric heating element and multiple rotating magnet motors installed on the knee brace body 1; an external device 3 is installed on the knee brace body 1, the external device 3 includes a battery and a microcontroller; the battery supplies power to the electric heating element, rotating magnet motors and microcontroller, the microcontroller is used to control the operation of the battery and microcontroller, the rotating magnet motor is used to drive the installed vibration head to vibrate, providing local massage, and the electric heating element can heat the knee brace body 1.

[0025] Example 3

[0026] like Figure 1 As shown in the figure, the knee brace structure proposed in this embodiment has pleats 6 at both the upper and lower ends of the middle part of the knee brace body 1 compared to the first embodiment. The pleats 6 are made of elastic bands. When the patient squats, the pleats 6 allow the knee brace body 1 to fit better against the knee and reduce discomfort.

[0027] Example 4

[0028] like Figure 1As shown, this embodiment proposes a knee brace structure. Compared to Embodiment 1, in this embodiment, the binding assembly includes a fixing strap 2, a square ring 19, a hook and loop fastener strap 51, and a hook and loop fastener strap 52. One end of the fixing strap 2 is connected to the end of the knee brace body 1. The hook and loop fastener strap 51 and the hook and loop fastener strap 52 are both mounted on the fixing strap 2. The square ring 19 is fixed to the knee brace body 1 and is located adjacent to the connecting end of the fixing strap 2. The binding assembly is then arranged according to the attached... Figure 1 The binding method is used to bind the knee brace 2 so that the fixing part of the fixing strap 2 is located on the front part of the knee brace body 1, so that the part of the fixing strap 2 adjacent to the back of the leg can remain flat, avoiding discomfort caused by the protrusion on the fixing strap 2 being squeezed between the thigh and calf when squatting.
