[0033] The utility model is further described below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 9 The knee and elbow pad assembly based on tactile perception shown includes a protective gear body 1, a flexible tactile sensor protection block 2 and a signal acquisition and processing device 3. The protective gear body 1 and the flexible tactile sensor protection block 2 are fixed by sewing and weaving. Three flexible tactile sensor protection blocks 2 are sewn on the front outer surface of the protective gear body 1 in upper, middle and lower parts. The middle flexible tactile sensor protection block 2 is circular, and the upper and lower flexible tactile sensor protection blocks 2 are semi-elliptical. The signal acquisition and processing device 3 is arranged above the front of the protective gear body 1, and a semi-elliptical flexible tactile sensor protection block 2 is arranged between the signal acquisition and processing device 3 and the circular flexible tactile sensor protection block 2. The aspect ratio of the flexible tactile sensor protection block 2 located at the lower part is greater than that of the flexible tactile sensor protection block 2 located at the upper part, and the two ends of the flexible tactile sensor protection block 2 located at the upper part extend to the sides of the limb.

[0035] The protective gear body 1 and the flexible tactile sensor protection block 2 both have a waterproof and breathable layer 7 and a heat-insulating layer 8, and a built-in buffer layer 9 for shock absorption and pressure reduction.

[0036] A 3D stereoscopic special-shaped curved surface tactile sensor 10 is also arranged in the flexible tactile sensor protection block 2 .

[0037] The protective gear body 1 also includes double-sided memory springs 11 for reinforcing support, straps 6 for pressurizing and stabilizing the fit, and reserved wiring openings 12 for hidden connection of FPC soft board leads 10-7 to the signal acquisition and processing device 3.

[0038] Each flexible tactile sensor protection block 2 comprises, from top to bottom, a waterproof and breathable layer 7, a heat-insulating layer 8, a buffer layer 9, a 3D three-dimensional special-shaped curved tactile sensor 10, and a waterproof and breathable layer 7. The two outermost layers of the waterproof and breathable layers 7 are fixed together by sewing and weaving. The waterproof and breathable layer on the side where the heat-insulating layer is located is in contact with the human body, and the waterproof and breathable layer 7 on the side where the 3D three-dimensional special-shaped curved tactile sensor 10 is located is away from the human body.

[0039] The waterproof and breathable layer 7, the buffer layer 8, and the heat-insulating layer 9 are all made of fully flexible breathable woven fabrics. The 3D stereoscopic special-shaped curved surface tactile sensor 10 is a three-dimensional special-shaped curved surface, which can fit closely and cover the joints of the elbows and knees and the vulnerable areas above and below the joints. While ensuring the wearing comfort, it meets the requirements of pressure reduction, shock absorption, stability and anti-slip, and at the same time solves the problem that the existing protective gear cannot perceive tactile information, assist movement, and issue alarms.

[0040] The 3D three-dimensional special-shaped curved surface tactile sensor 10 is an array structure, built into the flexible tactile sensor protection block 2, and can cover the three-dimensional special-shaped curved surface, with good lamination effect, can reduce the impact of wrinkles on sensor performance, and has high resolution and high sensitivity. Figure 4 ) From top to bottom, there are an upper profiled curved substrate 10-1, an upper electrode layer 10-2 arranged on the upper profiled curved substrate, a dielectric layer 10-3 between the upper and lower electrode layers, a lower electrode layer 10-4 arranged on the lower profiled curved substrate, and a lower profiled curved substrate 10-5.

[0041] The upper electrode layer 10-2 and the lower electrode layer 10-4 are respectively covered with row electrodes and vertical electrodes, and the electrodes are covered with an FPC soft board. The FPC soft board includes a front and a back side. The front side includes a plurality of leads 10-7, and the back side has a corresponding number of insulating patches 10-6. Each insulating patch 10-6 has a conductive contact at the center, and the conductive contact is in contact with the insulating patch 10-6. The center Z axis of each conductive contact is connected to (through) the FPC soft board and the positive side lead 10-7. Each conductive contact corresponds to a lead 10-7 on the positive side, and finally leads to the sensing area. A gold finger terminal 10-8 is set at the end of the lead 10-7.

[0042] Taking the upper electrode layer 10-2 as an example, the FPC soft board is an FPC row lead soft board, the front side of the FPC row lead soft board is attached to the upper special-shaped curved surface substrate 10-1, and the back side is attached to the row electrode attached to the upper electrode layer 10-2, and each electrode on the upper electrode layer is connected to the insulating patch 10-6 and the conductive contact on the FPC soft board in a covering form;

[0043] Taking the lower electrode layer 10-4 as an example, the FPC soft board is an FPC vertical lead soft board, the front side of the FPC vertical lead soft board is attached to the lower special-shaped curved surface base 10-5, and the back side is attached to the vertical electrode attached to the lower electrode layer 10-4, and each electrode on the lower electrode layer is connected to the insulating patch 10-5 and the conductive contact on the FPC soft board in a covering form. Adhesive is applied between adjacent layers of the 3D special-shaped curved surface tactile sensor 10 for packaging.

[0044] The packaging of the 3D stereoscopic special-shaped surface tactile sensor 10 is to apply adhesive between the parallel electrodes of the upper electrode layer and the lower electrode layer, and then place the upper electrode layer attached to the upper special-shaped curved surface substrate and the lower electrode layer attached to the lower special-shaped curved surface substrate perpendicular to each other, respectively close to the dielectric layer, so that the parallel electrodes are in contact with the dielectric layer to complete the packaging.

[0045] For example, the protective gear body 1 (see Figure 7 ) From inside to outside, they are respectively a waterproof breathable layer 7, a heat-insulating layer 8, a buffer layer 9 and a waterproof breathable layer 7. The first waterproof breathable layer is away from the human body as the outer waterproof breathable layer, and the second waterproof breathable layer is in contact with the human body as the inner waterproof breathable layer. A reserved wiring port 12 is provided in the layer structure between the outer waterproof breathable layer, the heat-insulating layer 8 and the buffer layer 9 for the FPC soft board lead 10-7 to be hiddenly connected to the signal acquisition and processing device 3. The protective gear body is composed of an upper and lower part, which are respectively worn tightly on the user's limbs through a sticky wool layer and a hook wool layer. In the area between the inner waterproof breathable layer and the buffer layer and located on both sides of the leg or elbow, a double-sided memory spring 11 (fish scale memory spring) is symmetrically provided along the height direction of the protective gear body for reinforcement and support. The fish scale memory spring has the characteristics of softness, elastic stability, and support and protection functions. A strap 6 is provided on the back of the protective gear body, with a sticky fleece layer 4 sewn on one side of the strap and a hook fleece layer 5 sewn on the other side. The binding length of the strap 6 can be adjusted by adjusting the length of the hook fleece layer 5 bonded to the sticky fleece layer 4 to adapt to wearers of different body shapes.

[0046] Exemplarily, the signal acquisition and processing device 3 is fixedly placed on the outer surface of the protective gear body 1, and is placed in a non-contact position of the knee joint or elbow joint during duty or exercise. The signal acquisition and processing device 3 has a built-in embedded microcontroller signal acquisition module, which is an integrated circuit board based on the STM32H743 core. The collected information is processed to obtain tactile perception information such as three-dimensional spatial position, contact center of mass, and equivalent pressure direction. The specific processing process can be implemented according to the existing technology.

[0047] The signal acquisition and processing device 3 is powered by a button battery.

[0048] The conductive contacts of the FPC row / vertical leads and the lead wires 10-7 are fixed in the layer structure of the protective gear body 1, and are connected to the signal acquisition and processing device 3 located on the protective gear body by the gold finger terminal 10-8. The signal acquisition and processing device 3 is connected to the host computer module via wireless, and the host computer module is provided with an early warning module to assist movement or intelligent alarm.

[0049] Exemplarily, the buffer layer 9 of the flexible tactile sensor protection block located in the middle is composed of an inner core made of a flexible elastic material and an annular silicone gasket wrapped around the outer periphery of the inner core, which increases the effects of pressure reduction, shock absorption, stability and anti-slip.

[0050] Exemplarily, the buffer layer 9 is made of high-rebound sponge or flexible elastic materials such as silicone shock-absorbing pads, silicone anti-slip strips, annular silicone gaskets, etc., and anti-sliding blocks are distributed on the front and back sides. The height of the anti-sliding blocks is about 2 mm to enhance the anti-slip and shock-absorbing effects.

[0051] The protective gear described in this specification includes an elbow pad and a knee pad. The elbow pad extends circumferentially from the elbow joint to surround part of the arm ( Figure 8 ), the knee pad extends circumferentially from the knee joint to surround part of the calf ( Fig. 9); When in use, first roughly adjust the binding length of the strap 6, then cover the protective gear body to the corresponding joint of the wearer, and finally adhere the hook layer 5 to the sticky layer 4 to adjust it to a comfortable wearing state. Turn on the recording switch of the signal acquisition and processing device 3, and you can start working or exercising. The sensor collects the displacement and force during the wearing process. When the initial position changes, a path in space will be generated, and the static and non-static time during the wearing process will be summarized. The non-static time is considered as the motion time, and the motion time is transmitted to the host computer module to monitor the motion duration and alarm. The calculation of the motion time is a prior art. Or the signal acquisition and processing device 3 does not summarize the motion time, and this process is implemented in the host computer. The signal acquisition and processing device 3 also transmits the perceived tactile information to the host computer module such as the PC terminal by wireless transmission. The processing results of the host computer module are transmitted to the sports bracelet, mobile phone APP, etc. by wireless transmission. If it is severely impacted, the 3D stereo special-shaped curved surface tactile sensor at the corresponding position will generate a force signal exceeding the set threshold, which will be transmitted to the host computer module and intelligent alarm.

[0052] In the utility model, data processing can be performed in the signal acquisition and processing device, or in the upper computer module, depending on the actual situation.

[0053] The above describes in detail the preferred specific embodiments of the utility model. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.

[0054] Anything not described in the present invention is applicable to the prior art.
