The end fixing buckle is inserted into the insertion hole to fix the grade ball and the pull-back spring. The pull-back spring abuts the grade ball against the fixing hole, and the diameter of the grade ball is set to be larger than the diameter of the fixing hole.

[0012] By adopting the above technical solution and arranging the pull-back spring, the pull-back spring can play a role in resetting the grade ball.

In the embodiment of the present application, the alkali-resistant primer can use a white alkali-resistant primer or a transparent alkali-resistant primer, and is rolled on the wall surface 1-2 times. The base coat 1 can play an alkali-resistant and salting-resistant role on the mortar layer of the wall. The collision sensing layer 2 is made by mixing a water-based EAU high-environmentally friendly synthetic sports venue material adhesive with elastic particles. The collision sensing layer 2 is evenly sprayed on the base coat 1. In the embodiment of the present application, the spraying thickness of the collision sensing layer 2 is 2 mm. When it is semi-dry, a strain gauge collision sensor 3 is embedded in the collision sensing layer 2. The elastic layer 4 is sprayed on the collision sensing layer 2, and the elastic layer 4 is made by mixing a water-based EAU high-environmentally friendly synthetic sports venue material adhesive with elastic particles. In the embodiment of the present application, the elastic layer 4 is sprayed 2-3 times, and the thickness range is 3-6 mm. The negative ion layer is sprayed on the elastic layer 4. The negative ion layer is made by mixing water-based EAU high-environmental synthetic sports field material adhesive with elastic powder. The negative ion layer is applied to the elastic layer 4 and scraped until the surface is smooth. After scraping, wait for it to be completely dried and then polished. The decorative surface layer 6 is specifically an elastic coating. The elastic coating is rolled on the polished leveling layer to form the decorative surface layer 6. In the embodiment of the present application, the decorative surface layer 6 is rolled twice.

[0032] Reference Figure 2 and Figure 6 , a plurality of strain gauge type collision sensors 3 are provided, and the strain gauge type collision sensors 3 are arranged at intervals. A port 37 is fixedly provided at the end of the strain gauge type collision sensor 3, and a wiring harness 38 is fixedly connected to the port 37, and current can be passed into the strain gauge type collision sensor 3 through the setting of the wiring harness 38. The strain gauge type collision sensor 3 also includes an outer ring 31, a circular through hole is reserved in the middle of the outer ring 31, an insulating block 32 is fixedly provided in the circular through hole, and an inner ring 33 is embedded and fixed in the middle position of the insulating block 32. A cavity 314 is opened inside the outer ring 31, and the outer ring 31 is set in a circular ring shape as a whole. A lower contact wall 317 is provided in the cavity 314, and the lower contact wall 317 is electrically connected to the wiring harness 38. The side of the outer ring 31 away from the base coating 1 is set as an upper contact wall 316, and insulation treatment is performed between the upper contact wall 316 and the lower contact wall 317.

[0033] Reference Figure 4 , 5 and Figure 6 The upper contact wall 316 is provided with a plurality of through holes to form a fixing hole 313, and the fixing hole 313 is connected to the cavity 314. A plurality of panels 3151 are fixedly arranged at positions corresponding to the fixing holes 313 in the cavity 314, and the two ends of the panels 3151 are respectively fixedly connected to the upper contact wall 316 and the lower contact wall 317, and the plurality of panels 3151 surround the fixing hole 313 to form a locking groove 315 in the cavity 314. A grade ball 311 is fixedly arranged in the locking groove 315, and the grade ball 311 is specifically set as a metal sphere. The two opposite ends of the grade ball 311 are provided with round holes to form an insertion hole 312. The diameter of the grade ball 311 is set to be larger than the diameter of the fixing hole 313. A pull-back spring 318 is fixedly provided on the upper contact wall 316. An end fixing buckle 319 is fixedly provided on the end of the pull-back spring 318 away from the upper contact wall 316. The pull-back spring 318 is inserted into the insertion hole 312 through the end fixing buckle 319, thereby fixing the pull-back spring 318 and the grade ball 311. The grade ball 311 is arranged inside the pull-back spring 318. The elastic force of the pull-back spring 318 makes the grade ball 311 contact the fixing hole 313. Since the diameter of the grade ball 311 is set to be larger than the diameter of the fixing hole 313, the grade ball 311 cannot pass through the fixing hole 313, but the part of the grade ball 311 smaller than its own radius can be exposed outside the fixing hole 313.

[0034] Reference Figure 7 The insulating block 32 is arranged between the inner ring 33 and the outer ring 31. The insulating block 32 is set to an insulating material. The inner ring 33 is provided with a circular hole to form an inner slot 34. A conductive flange 341 is fixedly arranged on the outer edge of the inner ring 33. The conductive flange 341 is bent along the outer edge of the inner ring 33 toward the inside of the inner ring 33. The conductive flange 341 is electrically connected to the wiring harness 38. A main ball 36 is movably arranged in the inner slot 34. The main ball 36 is set to be a metal ball. The volume of the main ball 36 is set to be larger than that of the grade ball 311. The conductive flange 341 has a limiting effect on the main ball 36, so that the main ball 36 cannot pass through the conductive flange 341. An air bag 35 is fixedly arranged at the bottom of the inner slot 34. The air bag 35 and the inner ring 33 are both set to insulating materials. The airbag 35 is made of a soft material and is elastic. There are round holes around the airbag 35 to form air holes 352. In a normal state, the airbag 35 expands and inflates by its own elastic force. The top of the airbag 35 is bent to form a round groove to form a spherical groove 351. When the airbag 35 is squeezed, the air inside the airbag 35 is squeezed out through the air holes 352, so that the airbag 35 is flattened. In the initial state, the main ball 36 is pressed in the spherical groove 351, and the airbag 35 expands and inflates by its own elasticity, so that the main ball 36 abuts against the conductive flange 341, so that one end of the main ball 36 is exposed outside the conductive flange 341.

[0035] The strain gauge type collision sensor 3 is also electrically connected to a signal transmitter, and a signal receiver is provided in conjunction with the signal transmitter. The signal receiver is provided as a mobile portable signal receiver.

[0036] The implementation principle of the embodiment of the present application is: after the base coating 1, the collision sensing layer 2, the elastic layer 4, the negative ion release layer 5 and the decorative surface layer 6 are sprayed in sequence, the wall surface has a certain elasticity, so that the wall surface has a certain elastic buffering capacity. When a collision occurs on the wall surface, the elastic buffering of the elastic layer 4 can reduce the degree of impact. The elastic layer 4 can produce collision or pressure deformation during buffering, and the collision or pressure deformation can be transmitted to the strain gauge type collision sensor 3. When the strain gauge type collision sensor 3 is pressed, the level ball 311 will contact the lower contact wall 317, thereby generating an energized closed loop, so that the signal transmitter transmits a signal, so that the operator can receive the signal in time and respond. When the pressing is completed, the pull-back spring 318 uses its own elastic force to pull the level ball 311 to abut against the upper contact wall 316, thereby disconnecting the circuit. When the main ball 36 is pressed, due to the setting of the airbag 35, the gas in the airbag 35 can only be discharged slowly. When the gas in the airbag 35 is discharged, the main ball 36 is not in contact with the conductive flange 341, so that the power circuit is disconnected, and the signal transmitter transmits a signal.

[0037] When the main ball 36 is subjected to an instantaneous impact, the gas in the airbag 35 cannot be discharged instantly, which will increase the resistance of the airbag 35, so that the main ball 36 cannot be separated from the conductive flange 341 in a short time, and a power closed loop continues to be generated between the conductive flange 341 and the main ball 36, so that the signal transmitter cannot transmit signals. According to the number of level balls 311 pressed at the same time, the contact area when the human body collides with the wall can be restored, thereby filtering out the contact area between the human body and the wall that is much larger than the normal human body and the wall, and the contact area between the human body and the wall that is much smaller than the normal human body and the wall, thereby filtering out invalid collisions and avoiding the signal transmitter from erroneously transmitting signals.

[0038] When the human body slowly contacts and presses the wall, the main ball 36 will be pressed away from the conductive flange 341, and the level ball 311 will be in contact with the lower contact wall 317. Since there is no low acceleration during the collision, the collision process in the above situation causes less harm to the human body. Therefore, when the level ball 311 is in contact with the lower contact wall 317, the main ball 36 is pressed and slowly separated from the conductive flange 341. In this case, the signal transmitter cannot send a signal, thereby filtering out invalid alarms and reducing the number of times the operator is invalidly reminded.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
