Technical Field

[0001] This utility model relates to the field of smart wearable device technology, and in particular to a smart air supply device for a patellar strap. Background Technology

[0002] Sports enthusiasts or athletes typically wear protective assistive devices, such as knee braces, to protect their knee joints from sports injuries. Studies have shown that proper use of knee braces can significantly reduce the occurrence of sports injuries.

[0003] In existing technologies, sports knee braces mostly adopt a long sleeve type that wraps around the entire knee joint. When athletes wear them for extended periods, knee movement becomes difficult, the knee joint is not easily bent, and it is prone to causing stuffiness and affecting normal exercise. To solve this problem, a narrow patellar band has been developed that is only worn at the patella. However, because this patellar band is relatively narrow, the space on the patellar band is small, which limits the space for installing an air supply device that adjusts the pressure. This not only affects the appearance of the patellar band but also limits the adjustment effectiveness of the air supply device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, an intelligent air supply device for a patellar brace includes a base 1, a top cover 2, and an airbag 3. The top cover 2 is detachably connected to the base 1. The airbag 3 is located on one side outside the base 1. An installation cavity 11 is provided between the base 1 and the top cover 2. An air pump 4, a pressure sensor 5, a four-way valve 6, a control board 7, and a battery 9 are housed within the installation cavity 11. The air pump 4 and the pressure sensor 5 are arranged side-by-side on one side of the four-way valve 6 and abut against it. The air pump 4 is a small air pump. The battery 9 is located close to the air pump 4, behind the pressure sensor 5, and provides power to the device. The control board 7 is located above the air pump 4 and is electrically connected to the air pump 4, the pressure sensor 5, the four-way valve 6, and the battery 9. The four-way valve... The valve 6 is located between the air pump 4 and the airbag 3, and has four channels: the first channel 61, the second channel 62, the third channel 63, and the fourth channel 64. The first channel 61 is connected to the airbag 3. The second channel 62 and the third channel 63 are located on the side where the air pump 4, the air pressure sensor 5, and the four-way valve 6 abut. The second channel 62 is connected to the air pump 4, and the third channel 63 is connected to the sensing end of the air pressure sensor 5. The fourth channel 64 is the deflation port, and the first channel 61 is connected to the third channel 63. The air pressure sensor 5 can directly detect the air pressure inside the airbag. The four-way valve 6 also has a valve core, which can switch the connection between the first channel 61 and the second channel 62 or the fourth channel 64, thereby inflating or deflating the airbag 3.

[0024] like Figure 2-5As shown, the first channel 51 is located on the side of the four-way valve 6 near the airbag 3. The airbag 3 has an air connector (not shown in the figure) on one side. The air connector extends into the base 1 and connects to the first channel 61. The air connector is connected to the airbag 3 by ultrasonic welding. The structure is simple, the connection is stable, and the pressure regulation effect is guaranteed.

[0025] The control motherboard 7 uses GR551x series chips, such as GR5515RGBC and GR5515CGNC, which are multifunctional, low-power, and support multiple power management modes.

[0026] During operation, the control motherboard 7 outputs the set pressure value, and the air pressure sensor 5 detects the pressure of the airbag 3 in real time and sends the detected pressure value to the control motherboard 7. The control motherboard 7 compares the detected pressure value with the set pressure value. If the detected pressure value is greater than the set pressure value, the control motherboard 7 controls the valve core of the four-way valve 6, connecting the first channel 61 and the fourth channel 64 to deflate the airbag 3 and reduce the pressure value. If the detected pressure value is less than the set pressure value, the control motherboard 7 controls the valve core of the four-way valve 6, connecting the first channel 51 and the second channel 62 to inflate the airbag 3 until the pressure value of the airbag 3 rises to the set pressure value. In addition, the air pump 4 and the air pressure sensor 5 are directly mounted against one side of the four-way valve 6, directly connected without air pipe connection, making the structure more compact, saving installation space, thereby reducing the size of the base 1 and making the appearance more aesthetically pleasing. Moreover, the direct connection of the air pressure sensor 5 to the airbag 3 results in more accurate detection results and improves the pressure regulation effect. In summary, this utility model has a compact structure, small size, and beautiful appearance. It can automatically adjust the airbag pressure through the air supply device, and the adjustment effect is good.

[0027] Example 2

[0028] Based on the structure of Example 1, such as Figure 1 , 2 As shown, the airbag 3 is embedded in the strap 8 on the side near the four-way valve 6, and is not overlapped with the base 1. The strap 8 is located on both sides of the base 1 and is used to wear the patellar strap.

[0029] Among them, such as Figure 2-4 As shown, the base 1 is a cabin-type structure, including a base 12 and a front seat 13 and a rear seat 14 respectively located on both sides of the base 12. The upper cover 2 is located inside the cabin of the base 1 and is connected to the base 1 by a snap-fit. The end of the airbag 3 near the four-way valve 6 extends into the interior of the front seat 13, so that the airbag 3 and the four-way valve 6 are positioned close together. The base 1 and the upper cover 2 form the functional outer shell of the patellar brace, which has a simple structure, is easy to assemble and disassemble, and has an aesthetically pleasing appearance.

[0030] like Figure 1As shown, a button 10 is provided at the top center of the upper cover 2. By pressing the button 10, the pressure value can be manually switched and set. Manually setting the pressure value by pressing the button 10 provides better flexibility and is convenient and quick. It also gives the device both automatic and manual adjustment modes, making it more functional and providing a better user experience.
