Although it has better protective effect than the traditional single-layer soft pad knee pad, there are still some shortcomings in use. For example, when wearing the protective device described therein, the protective device needs to be tied tightly to the knee. However, if the user's knee is already injured, if the protective device is still directly attached to the knee, the injured part of the knee will continue to be pressed by the protective device during the user's exercise, causing pain, and the user experience is very poor.

[0005] Therefore, the present application proposes a knee protection device to solve the above-mentioned deficiencies. Utility Model Content

[0006] The utility model provides a knee protection device to solve the above technical problems.

[0007] In order to solve the above technical problems, the utility model provides a knee protection device, comprising a knee pad mechanism and two height-increasing mechanisms, wherein the knee pad mechanism is located between the two height-increasing mechanisms;

[0008] The knee pad mechanism is composed of a guard plate and a protective air cushion, and the protective air cushion is fixedly connected to the inner side of the guard plate;

[0009] The height-increasing mechanism is composed of a connecting plate and a height-increasing air cushion, and the height-increasing air cushion is fixedly connected to the inner side of the connecting plate;

[0010] A plurality of connecting ropes are fixedly connected between the guard plate and the connecting plate.

[0011] Preferably, a buffer mechanism is installed on the outside of the guard plate, and the buffer mechanism includes a buffer plate, and the buffer plate is located on the outside of the guard plate. A connecting cotton block and four springs are fixedly connected between the guard plate and the buffer plate. The four springs are respectively located at the four corners of the buffer plate, and the connecting cotton block is located between the four springs.

[0012] Preferably, the top, bottom and rear side of the height-increasing air cushion are respectively provided with a plurality of ventilation holes.

[0013] Preferably, the rear side of the height-increasing air cushion is connected to a sponge pad via Velcro.

[0014] Preferably, a binding strap is fixedly connected to the side edge of the connecting plate.

[0015] Compared with the related art, the knee protection device provided by the utility model has the following beneficial effects:

[0016] The knee protection device is divided into a knee pad mechanism and two height-increasing mechanisms, and the height-increasing mechanisms are tied above and below the knee so that the knee pad mechanism is directly in front of the knee. Since the knee pad mechanism is connected between the two height-increasing mechanisms through a connecting rope, and the protective air cushion in the knee pad mechanism is not as thick as the height-increasing air cushion, the knee pad mechanism is only located in front of the knee and does not contact the knee. This can not only protect the user's knees during exercise, but also avoid the problem of the protective device pressing on the knee and causing pain in the old injury, providing a better user experience.

[0023] Example, by Figure 1-5 It is given that the utility model comprises a knee pad mechanism and two height-increasing mechanisms, wherein the knee pad mechanism is located between the two height-increasing mechanisms;

[0024] The knee pad mechanism is composed of a guard plate 1 and a protective air cushion 2, and the protective air cushion 2 is fixedly connected to the inner side of the guard plate 1;

[0025] The height-increasing mechanism is composed of a connecting plate 3 and a height-increasing air cushion 5, and the height-increasing air cushion 5 is fixedly connected to the inner side of the connecting plate 3;

[0026] A plurality of connecting ropes 4 are fixedly connected between the guard plate 1 and the connecting plate 3 .

[0027] The thickness of the protective air cushion 2 is smaller than that of the height-enhancing air cushion 5, and under normal circumstances, the connecting plate 3 and the guard plate 1 are basically in the same plane, so that although the knee pad mechanism is located in front of the knee, it is not in contact with the knee all the time, avoiding the old injury on the knee from being pressed and rubbed and causing pain, resulting in a poor user experience.

[0028] A buffer mechanism is installed on the outside of the guard plate 1, and the buffer mechanism includes a buffer plate 9. The buffer plate 9 is located on the outside of the guard plate 1. A connecting cotton block 10 and four springs 11 are fixedly connected between the guard plate 1 and the buffer plate 9. The four springs 11 are respectively located at the four corners of the buffer plate 9. The connecting cotton block 10 is located between the four springs 11. The buffer mechanism can play a preliminary buffering role when the user falls or the knee is hit by foreign objects.

[0029] The top, bottom and back side of the height-increasing air cushion 5 are respectively provided with a plurality of ventilation holes 6, and the back side of the height-increasing air cushion 5 is connected with a sponge pad 7 by Velcro. The arrangement of the ventilation holes 6 and the sponge pad 7 can increase the breathability of the leg skin during use, and the arrangement of the ventilation holes 6 can also improve the resilience of the height-increasing air cushion 5. At the same time, the sponge pad 7 sandwiched between the skin and the height-increasing air cushion 5 can also improve the skin comfort.

[0030] The side of the connecting plate 3 is fixedly connected with a strap 8, and the height-increasing mechanism can be tied to the legs above and below the knees through the strap 8.

[0031] Working principle:

[0032] When in use, the two height-increasing mechanisms are respectively tied to the thigh and calf above and below the knee by the straps 8, and the kneepad mechanism is located just in front of the knee. At this time, due to the support of the height-increasing air cushion 5, there is a large gap between the connecting plate 3 and the leg, and the guard plate 1 is connected between the two connecting plates 3 by the connecting rope 4, so it is also at a certain distance from the knee. In addition, the protective air cushion 2 on the inner side of the guard plate 1 is not as thick as the height-increasing air cushion 5 and cannot touch the knee either. When the protective device is worn, the guard plate 1 and the protective air cushion 2 will not touch each other during the user's normal exercise. The knee is pressed, and when the user falls or an external object hits the knee, the first thing that comes into contact with the external object or the ground is the buffer plate 9. The impact force received by the buffer plate 9 will compress the spring 11 during the process of being transmitted to the guard plate 1, causing it to generate elastic force. During the process, the spring 11 can buffer the impact force received by the buffer plate 9 and then transmit it to the guard plate 1. At this time, the guard plate 1 will move toward the user's knee with the impact force until the user's knee hits the protective air cushion 2 on the inner side of the guard plate 1. The protective air cushion 2 can play a buffering and protective role on the knee.
