Technical Field

[0001] The present invention relates to the field of smart home technology, in particular to a ground safety buffer system and a working method of the ground safety buffer system. Background Art

[0002] In home decoration, ceramic tiles are a common floor decoration material. However, in daily use, family members, especially the elderly and children, may accidentally fall while walking, and direct contact with the hard ceramic tile surface can easily cause injuries. Traditional solutions mostly rely on increasing the friction coefficient of the ground or improving furniture design to reduce injuries, but these methods can only prevent falls, but cannot reduce the injuries after falls. Summary of the invention

[0003] In order to reduce the damage to the body caused by a user falling down, the present invention provides a ground safety buffer system and a working method thereof. The ground safety buffer system includes an airbag. After the user falls down and before the user hits the ground, the airbag can pop out and inflate, thereby reducing the impact caused by the fall and reducing the degree of injury.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A ground safety buffer system includes a ground decoration block, a control unit and an information collection unit. The multiple ground decoration blocks are arranged in rows and columns, and an airbag installation area is formed between two adjacent ground decoration blocks. A safety airbag is arranged in the airbag installation area, and the safety airbag is connected to an inflation unit. The information collection unit can collect user behavior information in real time and send it to the control unit. The control unit can make the safety airbag move upward and leave the airbag installation area. The control unit can also make the inflation unit inflate air into the safety airbag.

[0006] A working method of the above-mentioned ground safety buffer system comprises the following steps:

[0007] The information collection unit collects the user's behavior information on the ground decoration block in real time and sends it to the control unit. The control unit determines whether the user falls based on the behavior information. When the control unit determines that the user falls, the control unit causes the airbag corresponding to the user's fall site to move upward and leave the airbag installation area. The control unit can also cause the inflation unit to inflate the airbag that has left the airbag installation area.

[0008] The beneficial effects of the present invention are:

[0009] 1. Security protection:

[0010] When you fall, it can effectively reduce the impact of the fall, reduce the degree of injury, and play a role in safety protection.

[0011] 2. Intelligent identification:

[0012] Through the use of sensors, cameras and intelligent control systems, the buffer mechanism is activated only when needed to avoid false triggering.

[0013] 3. Easy to install and maintain:

[0014] It adopts the form of elevated ground and dry construction, which can be combined with conventional tile laying technology, with flexible wiring and easy installation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0032] For the convenience of understanding and description, an absolute positional relationship is adopted in the following description of the present invention. Without special instructions, the orientation word "up" represents Figure 1 the upper side direction in Figure 1 the lower side direction in Figure 1 the left side direction in Figure 1 the right side direction in Figure 1 the direction perpendicular to the Figure 1 paper surface of

[0033] such as Figure 1 to Figure 2 shown, a ground safety buffer system described in an embodiment of the present invention includes a ground decoration block 1, a control unit 2, and an information collection unit 3. A plurality of ground decoration blocks 1 are arranged in rows and columns. An airbag installation area 4 is formed between two adjacent ground decoration blocks 1. A safety airbag 41 is arranged in the airbag installation area 4. The safety airbag 41 is connected to an inflation unit 42. The information collection unit 3 can collect the behavior information of the user in real time and send it to the control unit 2. The control unit 2 can make the safety airbag 41 move upward and leave the airbag installation area 4. The control unit 2 can also make the inflation unit 42 inflate the safety airbag 41.

[0034] The ground decoration block 1 has a rectangular plate-like structure. The ground decoration block 1 is fixedly installed on the floor slab 5. The ground decoration block 1 is parallel to the horizontal plane. The ground decoration block 1 includes an overhead layer 11, a support plate layer 12, a balance plate layer 13, an adhesive layer 14, and a decorative surface layer 15 that are sequentially stacked from bottom to top.

[0035] such as Figure 1 to Figure 2As shown, a support frame 16 is provided in the overhead layer 11, and the support plate layer 12 is connected and fixed to the floor 5 through the support frame 16. Preferably, the inflation unit 42 can be located in the overhead layer 11, and the connection line between the control unit 2 and the information acquisition unit 3 can also be located in the overhead layer 11. The overhead layer 11 is a space for laying power lines and communication lines required for the buffer control system, and other electromechanical pipelines can also be laid.

[0036] The thickness of the overhead layer 11 can be 20mm-40mm, the thickness of the supporting board layer 12 can be 20mm-40mm, the thickness of the balancing board layer 13 can be 5mm-10mm, the thickness of the adhesive layer 14 can be 3mm-8mm, and the decorative surface layer 15 can be a tile layer or a floor layer, that is, the material of the decorative surface layer 15 can be a tile.

[0037] The material of the balancing board layer 13 is calcium silicate board. The balancing board layer 13 is used to increase the load and rigidity of the elevated floor and reduce the impact of noise on the lower floor. The function of the adhesive layer 14 is to connect the decorative surface layer 15 and the balancing board layer 13. The material of the adhesive layer 14 can be tile adhesive.

[0038] Preferably, the thickness of the overhead layer 11 is 30 mm, the thickness of the supporting plate layer 12 is 30 mm, the thickness of the balancing plate layer 13 is 8 mm, the thickness of the adhesive layer 14 is 5 mm, and the decorative surface layer 15 is a ceramic tile layer.

[0039] The information acquisition unit 3 includes a pressure sensor, for example, an array distributed pressure sensor 31. The array distributed pressure sensor 31 can adopt an existing piezoresistive array distributed flexible film pressure sensor. For example, the manufacturer of the array distributed pressure sensor 31 is Suqian Ruohua Information Technology Co., Ltd., and the production model is RX-M1616M piezoresistive array distributed flexible film pressure sensor.

[0040] The pressure sensor (array distributed pressure sensor 31) is used to monitor the pressure change on the ground in real time, can sense the abnormal impact force generated when a person falls, and transmit the signal to the control unit 2. The array distributed pressure sensor 31 and the decorative surface layer 15 can be stacked up and down or stacked up and down.

[0041] The array distributed pressure sensor 31 and the decorative surface layer 15 can be connected in the following ways: placing the array distributed pressure sensor 31 and its leads in a tile manufacturing mold to ensure that the sensor is stable and flat, pouring the mixed tile manufacturing material into the mold to ensure that the manufacturing material covers the sensor and fills the entire mold, using a special tool to compact it to remove bubbles and ensure that the sensor is tightly combined with the tile manufacturing material; after the tile is fired, the sensitivity of the array distributed pressure sensor 31 in the tile is tested to ensure that it can sensitively and accurately sense pressure changes and work properly. Alternatively, the array distributed pressure sensor 31 and the decorative surface layer 15 can also be connected by bonding.

[0042] The information collection unit 3 and the control unit 2 are connected by a cable. In order to improve security, the information collection unit 3 also includes an intelligent camera 32. The intelligent camera 32 can use an existing AI intelligent camera. The intelligent camera 32 captures the user's behavior information in real time. The control unit 2 is connected to a wireless signal transceiver unit. The control unit 2 can achieve wireless communication with the smartphone through the wireless signal transceiver unit.

[0043] like Figure 1 to Figure 2 As shown, in order to allow the airbag installation area 4 to be quickly and completely detached from the airbag installation area 4 when needed, the airbag installation area 4 contains an airbag ejection mechanism 43, and the control unit 2 can control the airbag ejection mechanism 43 to move the safety airbag 41 upward and away from the airbag installation area 4.

[0044] The width of the airbag installation area 4 is 15mm-30mm (such as 20mm), the height of the airbag installation area 4 is basically the same as the height of the ground decoration block 1, the airbag ejection mechanism 43 includes a bracket 431, a spring 432 and an actuator 433 connected in sequence from top to bottom, the airbag 41 is located on the left and right sides of the bracket 431, the actuator 433 is connected to the control unit 2, and the actuator 433 can change the spring 432 from a compressed state to an extended state.

[0045] like Figures 2 to 4 As shown, the actuator 433 may include a pressure pin 4331 and an electromagnet 4332 which are arranged inside and outside, and a spring 432 is arranged outside the pressure pin 4331. The pressure pin 4331 is made of ferromagnetic material, and the head of the pressure pin 4331 faces upward, and the spring 432 is located between the head of the pressure pin 4331 and the upper end of the electromagnet 4332. When the electromagnet 4332 is energized, the electromagnet 4332 attracts the pressure pin 4331 by magnetic force, and the spring 432 is in a compressed state; when the electromagnet 4332 loses power, the magnetic force received by the pressure pin 4331 disappears, and the spring 432 stretches to push the pressure pin 4331 upward, so that the bracket 431 and the airbag 41 both move upward and leave the airbag installation area 4.

[0046] The cross section of the bracket 431 is T-shaped. The bracket 431 includes a top plate 4311 and a vertical plate 4312 connected up and down. The middle of the upper surface of the top plate 4311 is concave downward. The left and right ends of the top plate 4311 are both flush with the upper surface of the floor decoration block 1. The airbag 41 is located on the left and right sides of the vertical plate 4312. Part of the airbag 41 is connected (bonded) and fixed to the vertical plate 4312. The middle of the upper surface of the top plate 4311 is concave downward to ensure that the ground water will not flow into the airbag installation area 4. The top plate 4311 is made of stainless steel or aluminum alloy, and the color is consistent with the color of the floor tile caulking agent.

[0047] Alternatively, the airbag ejection mechanism 43 may also use an ejection airbag, which is connected to an inflation unit. The safety airbag 41 and the ejection airbag are connected up and down in the airbag installation area 4. When the ejection airbag is located in the airbag installation area 4, the ejection airbag is in an uninflated state. When the safety airbag 41 is required to move upward and leave the airbag installation area 4, the inflation unit inflates the ejection airbag to make the safety airbag 41 quickly leave the airbag installation area 4.

[0048] When the airbag 41 is located in the airbag installation area 4, the airbag 41 is in an uninflated state and is folded and stored in the airbag installation area 4; when the airbag 41 is located outside the airbag installation area 4, the control unit 2 can control the inflation unit 42 to inflate the airbag 41 and put the airbag 41 in an inflated state. At this time, the airbag 41 is inflated and expanded, and the height of the inflated airbag 41 can be 150mm-200mm.

[0049] The inflation method of the airbag 41 can adopt the inflation method of the automobile airbag in the prior art. For example, the inflation unit 42 includes a gas generator and an igniter connected in sequence. The gas generator is connected to the airbag 41 through a gas pipeline, and the igniter is connected to the control unit 2. The inflation unit 42 can be located in the overhead layer 11.

[0050] After the safety airbag 41 is released, it can be compressed and reset to the airbag installation area 4 by an air pressure pump. By pressing and pushing the bracket 431, the spring 432 is compressed to reset the airbag ejection mechanism 43, ensuring that the surface of the tile is flat and does not affect normal use.

[0051] The airbags 41 in each airbag installation area 4 are independent of each other, the inflation units 42 connected to each airbag 41 are also independent of each other, and the airbag ejection mechanisms 43 corresponding to each airbag 41 are also independent of each other. Each inflation unit 42 and the airbag ejection mechanism 43 are connected to the control unit 2. The control unit 2 can determine the fall position of the user and only control the airbag ejection mechanism 43 within a certain range of the fall position to operate, so that only the airbags 41 within a certain range of the fall position are ejected, and only the inflation units 42 within a certain range of the fall position inflate the airbags 41.

[0052] like Figures 5 to 7 As shown, the signal and power lines of the array distributed pressure sensor 31 are connected to the control unit 2 through the airbag installation area 4 via the overhead layer 11; the signal and power lines of the actuator 433 are connected to the control unit 2 through the overhead layer 11; the signal and power lines of the smart camera 32 are connected to the control unit 2 through the pipe along the wall, the control unit 2 is connected to the power supply 44, and the control unit 2 can be installed in a household low-voltage box.

[0053] The control unit 2 can use an existing microprocessor. For example, the manufacturer of the control unit 2 is Shenzhen Taichengxing Electronic Technology Co., Ltd. The production model of the control unit 2 is ALXD800EEXJ2VD microprocessor, which has multiple wireless communication technologies, including WiFi, Bluetooth, ZigBee, and is compatible with multiple communication protocol functions. At the same time, it can be viewed and operated through a mobile phone APP, that is, the control unit 2 is wirelessly connected to the mobile phone 45. The control unit 2 can be connected to the property alarm control system. After receiving the alarm signal, the control unit 2 can simultaneously send an alarm signal to the property alarm system and the owner supervisor's mobile phone APP, so as to promptly notify the property or supervisor to rescue the fallen person.

[0054] The working method of the above-mentioned ground safety buffer system is introduced below. The working method of the ground safety buffer system includes the following steps:

[0055] like Figure 6 to Figure 7 As shown, the information collection unit 3 collects the user's behavior information on the ground decoration block 1 in real time and sends it to the control unit 2. The control unit 2 determines whether the user falls down based on the behavior information. When the control unit 2 determines that the user falls down, the control unit 2 causes the airbag 41 corresponding to the user's fall location (within a set range) to move upward and leave the airbag installation area 4. The control unit 2 can also cause the inflation unit 42 to inflate the airbag 41 that has left the airbag installation area 4.

[0056] It can be understood that, under normal circumstances, the airbag 41 is folded and stored in the airbag installation area 4, the airbag 41 is in an uninflated state, and the spring 432 is in a compressed state; when the control unit 2 determines whether the user falls, the control unit 2 sends a signal to the airbag ejection mechanism 43, the electromagnet 4332 loses power, the spring 432 extends to push the airbag 41 out of the airbag installation area 4, and the inflation unit 42 inflates the airbag 41 that has left the airbag installation area 4. After the airbag 41 is inflated, it expands and is quickly laid under the body of the faller, forming a soft cushion to prevent the body of the faller from directly contacting the floor tiles, thereby playing a role of safety cushioning and protection. The release action time of the airbag 41 is 80ms.

[0057] The control unit 2 can determine whether the user has fallen based on the behavior information based on a limited number of experimental simulations. For example, the information acquisition unit 3 is a pressure sensor, which can collect and record characteristic pressure signals by simulating the user's fall, and compare the real-time collected pressure signals with the characteristic pressure signals. If they are consistent, it is determined whether the user has fallen. For example, the information acquisition unit 3 is an intelligent camera 32, which can collect and record characteristic video information by simulating the user's fall, and compare the real-time collected video information with the characteristic video information. If they are consistent, it is determined whether the user has fallen.

[0058] When one of the pressure signals or video information collected in real time can determine whether the user falls, the control unit 2 will immediately cause the airbag 41 corresponding to the user's fall location (within the set range) to move upward and leave the airbag installation area 4. The control unit 2 can also cause the inflation unit 42 to inflate the airbag 41 that has left the airbag installation area 4.

[0059] The above is only a specific embodiment of the present invention, and cannot be used to limit the scope of the invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the protection scope of the present invention should still fall within the scope of the present invention. In addition, the technical features in the present invention can be freely combined with each other, with technical features and technical solutions, and with technical solutions.
