Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 3, the invention also provides a mattress supporting and sensing device, which comprises a cushion block 10 and a micro-motion sensor 20, wherein the micro-motion sensor 20 is arranged on the upper surface of the cushion block 10; when in use, the cushion block 10 is placed on the bed board, and the micro-motion sensor 20 faces the mattress 40; the micro-motion sensor is detachably connected with the cushion block so as to facilitate replacement of the cushion block; the thickness of the pad 10 is adjusted according to the sensitivity of the micro-motion sensor 20 and the elasticity and thickness of the mattress 40.

In this embodiment, the spacer 10 is a thick object, generally a rigid object, which can increase the height of the micro-motion sensor 20 supporting the mattress 40, thereby increasing the acquisition area and the acquisition sensitivity of the micro-motion sensor 20. The micro sensor 20 is a sensor for collecting a vibration signal of the mattress 40, and may be a piezoelectric sensor, a piezoelectric ceramic sensor, a moving magnetic sensor, or the like. The sensitivity of the micro-motion sensor 20 is related to its own sensing device, and the higher the pressure is, the higher the sensitivity of the micro-motion sensor is. The mattress 40 is generally elastic to make the person more comfortable when lying on the bed, but different mattresses 40 have different elasticity and thickness, for example, the elasticity of the spring mattress 40 is generally larger than that of the memory cotton mattress 40, and the thickness is determined according to the requirement of the user. Because the elasticity of the mattress 40 is different, when the micro-motion sensor 20 is placed at the bottom of the mattress 40, the supporting height of the micro-motion sensor is the same, but the strength of the collected vibration signals is different, the same person acts on the mattress 40 in the same way, the vibration signals generated by the mattress 40 with large elasticity and large thickness are obviously smaller than the strength of the vibration signals generated by the mattress 40 with small elasticity and small thickness, therefore, in order to obtain the vibration signals with good consistency, the thickness of the cushion block 10 under the mattress 40 with small elasticity and small thickness can be reduced, the strength of the micro-motion signals collected by the micro-motion sensor 20 is weakened, otherwise, the thickness of the cushion block 10 of the mattress 40 with large elasticity and large thickness is increased, and the strength of the micro-motion signals collected by the micro-motion sensor 20 is strengthened. That is, the thickness and elasticity of the mattress 40 are inversely related to the strength of the vibration signal, i.e., the thicker the mattress 40, the smaller the vibration signal; the greater the resilience of the mattress 40, the smaller the vibration signal.

In this embodiment, the cushion blocks 10 include multiple specifications, wherein a first fixing position is disposed at the center of the top surface of each cushion block 10, a second fixing position is disposed at one end of the micro sensor 20 along the force-receiving direction, the cushion blocks 10 and the micro sensor 20 are detachably connected through the first fixing positions and the second fixing positions, and the area of the top surface of the cushion block 10 is larger than or equal to the area of the end surface of the end of the second fixing position where the micro sensor 20 is disposed.

The cushion block 10 is provided with various specifications, namely cushion blocks 10 with different thicknesses and sizes. The cushion block 10 and the micro-motion sensor 20 are detachably connected through the first fixing position and the second fixing position, so that the cushion block 10 with large thickness can be selected for the mattress 40 with large elasticity, and the cushion block 10 with small thickness can be selected for the mattress 40 with small elasticity. The cushion block 10 and the micro-motion sensor 20 are detachably connected, so that the cushion block 10 can be conveniently replaced. The area of the top surface of the cushion block 10 is larger than or equal to the area of the end surface of the end of the micro-motion sensor 20, which is provided with the second fixing position, so that the stability of the micro-motion sensor 20 placed under the mattress 40 can be improved. In one embodiment, if the deck supporting the mattress 40 is in the form of a grid, care should be taken to keep the area of the bottom surface of the pillow 10 from falling out of the grid.

In this embodiment, a groove is formed on the top surface of the pad 10 to form the first fixing position, and a flange is formed on the micro sensor 20 to form the second fixing position, wherein the flange is fittingly inserted into the groove. The micro-motion sensor 20 can be quickly installed on the cushion block 10, the position between the cushion block 10 and the micro-motion sensor 20 is relatively stable, and the cushion blocks 10 with different specifications can be conveniently and quickly replaced.

In this embodiment, a through hole penetrating through the spacer 10 is formed at the bottom of the groove, a screw hole is formed at the center of the flange, and after the micro sensor 20 is inserted into the spacer 10, a screw 11 is inserted through the through hole and screwed into the screw hole, so that the spacer 10 and the micro sensor 20 are fixed together. The cushion block 10 and the micro-motion sensor 20 are further fixed through the screw 11, so that the stability between the micro-motion sensor 20 and the cushion block 10 can be improved, and the condition that the micro-motion sensor 20 is damaged due to the fact that the flange is not inserted into the groove just right when the cushion block 10 is replaced is prevented. In this embodiment, a counter bore is provided at the front end of the through hole for hiding the nut of the screw.

In this embodiment, a pressing block 30 is installed at one end of the micro-motion sensor 20 away from the cushion block 10, wherein a third fixing position is arranged at the center of the bottom surface of the pressing block 30, a fourth fixing position is arranged at the other end of the micro-motion sensor 20 corresponding to the second fixing position, and the pressing block 30 and the micro-motion sensor 20 are detachably connected through the third fixing position and the fourth fixing position; the area of the top surface of the pressing block 30 is larger than or equal to the area of the end surface of the end of the micro-motion sensor 20, which is provided with the fourth fixing position. A pressing block 30 is arranged above the micro-motion sensor 20, and the structure of the pressing block 30 can be symmetrical and the same as the structure of the cushion block 10. The pressing block 30 can improve the effective collection area of the micro sensor 20, and the design of the pressing block 30 can improve the collection sensitivity of the micro sensor 20 after the sensitivity of the micro sensor 20 is certain.

Referring to fig. 1 and 3, in one embodiment, one or more micro-motion sensors 20 mounted on the spacer blocks 10 are placed under the mattress 40, and due to the presence of the spacer blocks 10, the mattress 40 is lifted higher up in correspondence with the micro-motion sensors 20. Therefore, the pressure collected by the micro-motion sensor 20 at the position is larger, the collection sensitivity is improved, and when the elasticity of the mattress 40 is larger, the thicker cushion block 10 can be replaced according to the use condition. When the cushion block 10 is replaced, the flange at the bottom of the micro sensor 20 is inserted into the groove on the top surface of the cushion block 10, and then the micro sensor 20 and the cushion block 10 are further fixed by the screw 11, in other embodiments, the two can be connected by other detachable structures.

Referring to fig. 2 and 4, in another embodiment, a pressing block 30 is disposed on the top surface of the micro-motion sensor 20, a rim groove is disposed on the bottom surface of the pressing block 30, a through hole is also disposed on the bottom wall of the rim groove, a screw hole is also disposed on a flange disposed on the top surface of the micro-motion sensor 20, and a screw 31 fixedly connects the pressing block 30 and the micro-motion sensor 20. When the micro-motion sensor 20 with the cushion block 10 and the pressing block 30 is placed under the mattress 40, when the elasticity of the mattress 40 is small, the cushion block 10 can be replaced by the cushion block 10 with small thickness, the pressing block 30 with proper top surface area can be replaced by the pressing block 30 according to the requirement of acquisition area, if the acquisition range of the micro-motion sensor 20 needs to be increased, the pressing block 30 with large top surface area is replaced, otherwise, the pressing block 30 with small top surface area is replaced. In other embodiments, the pressing block 30 with different thickness can be replaced to adjust the collection sensitivity of the micro-motion sensor 20.

The mattress 40 of this embodiment supports the device of sensing to adjust the collection sensitivity and the effective sensing scope of microsensor 20 through the thickness of adjusting cushion 10, can carry out the adaptability to the mattress 40 of different elasticity, different thickness and adjust, make things convenient for the good intelligent mattress of large batch production uniformity.
