Technical Field

The utility model relates to the sensing field especially involves passive sensing device, equipment and passive drive arrangement.

Background

Intelligent management systems such as intelligent home and intelligent security are popular with consumers, and in the intelligent home and the intelligent management systems, sensors are very important devices, and intelligent control and management of a preset environment need to be performed by means of information acquired by the sensors. For example, the door needs to be provided with a sensor, and when the door is opened based on the sensor on the door, the relevant processor controls the relevant equipment in the environment to start, such as automatic light-on or automatic air-conditioning. For example, in a public washroom, a door may also be provided with a sensor, and based on the detection of the sensor, the relevant management department may know whether someone is inside the door to arrange for the person to clean at the right time, and if the sensor does not detect a signal again for a long time, this means that the toilet is occupied for a long time, the relevant management department may arrange for the person to check to prevent this.

Limited to the mounting location and size, such sensors are typically designed with a battery built in to meet operational requirements. This means that the user needs to replace the battery in time, and the whole smart home system or the smart security system will fail. At present, there is a sensor which works in a self-powered manner and is provided with a generator to supply power for self-working, but in practical use, the generator is difficult to drive due to large acting force required by the generator to drive when the door is opened, so that the sensor is very inconvenient to use.

In addition, although the types of such sensors are various at present, the application scenario of a single type of sensor is single. That is, the door sensor can be generally applied only to a door, the window sensor can be generally applied only to a window, and the sensor types may need to be further divided based on the difference in the opening and closing type of the door or the opening type of the window, such as a sliding door or a revolving door.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 5, a passive driving device 100 and a passive sensing device 1 according to a first preferred embodiment of the present invention are illustrated. The passive sensing device 1 can be used by being mounted to a target object, which may be, but is not limited to, a door, a window, a lock, etc. For example, when the door is displaced, for example, closed or opened, the passive sensing device 1 can detect the change to send a signal, so that the entire intelligent system can collect data in time to take corresponding measures in subsequent steps.

The operation of the passive sensing device 1 automatically generates electrical energy based on the pressure variations to which it is subjected, thereby transmitting a signal. The passive sensing device 1 may include the passive driving device 100, and the passive driving device 100 may automatically generate electric energy based on the pressure change to which it is subjected.

In detail, the passive sensing device 1 may include a force guiding mechanism 10, a power generating unit 20, and a communication unit 30, wherein the force guiding mechanism 10 is configured to transmit an external force to the power generating unit 20 to drive the power generating unit 20 to generate sufficient electric energy for the communication unit 30 to normally operate to send a signal to the outside, wherein the power generating unit 20 is configured to convert mechanical energy into electric energy, and the communication unit 30 is configured to transmit a signal to the outside. The passive driving apparatus 100 may include the force guide mechanism 10, the power generation unit 20, and the communication unit 30.

At least part of the power generating unit 20 can be moved by the force guide 10 and convert mechanical energy into electrical energy during the movement. It is noted that at least part of the movement of the power generating unit 20 is a reciprocating movement, such as a reciprocating linear movement, and therefore there is a certain requirement for the direction of the force applied to at least part of the power generating unit 20.

The force guide mechanism 10 can receive forces in different directions and transmit them to the power generation unit 20 in a manner that meets the requirements of the power generation unit 20 for movement, so that the power generation unit 20 is driven to generate electricity. In this way, the passive sensor device 1 has a reduced requirement for the force applied to it, not requiring a fixing in a certain direction, which is advantageous for expanding the range of applications of the passive sensor device 1. For example, the original passive sensing device 1 may require that an external force is applied from a forward horizontal direction of the force guiding mechanism 10 of the passive sensing device 1, for example, when the passive sensing device 1 is disposed on a sliding door, a forward horizontal force is applied to the force guiding mechanism 10 when the sliding door is closed. In the present embodiment, since the force guide mechanism 10 can receive forces in different directions, when the passive sensor device 1 is disposed on a common swing door, when the swing door is closed and a lateral horizontal thrust is applied, the force guide mechanism 10 of the passive sensor device 1 can still drive the power generation unit 20. In other words, the application range of the passive sensor device 1 can be expanded.

In more detail, the force guiding mechanism 10 has a first end 101 and a second end 102, the second end 102 is a free end for receiving the acting force and may be a force in different directions, and the force guiding mechanism 10 may change the force in different directions into a force in the same direction and then transmit the force to the power generation unit 20 at the position of the second end 102. In other words, the acting force received by the force guide 10 may be anisotropic, for example, a positive acting force acts on the first end 101 of the force guide 10 or a lateral acting force acts on the first end 101 of the force guide 10, but the direction of the acting force transmitted by the force guide 10 from the previous time to the next time is constant, so as to properly drive the power generation unit 20.

In more detail, the force guiding mechanism 10 may include a force guiding member 11 and a driving member 12, wherein the force guiding member 11 is configured to receive an external force, the driving member 12 is configured to transmit the force from the force guiding member 11 to the power generating unit 20, and the transmitted force is suitable for driving the power generating unit 20. The driving member 12 is located between the power generating unit 20 and the force guide 11. One end of the force guide 11 is used for receiving external force, and the other end of the force guide 11 is configured to drive the driving member 12. One end of the driving member 12 is configured to be driven by the force guide 11, and the other end is configured to drive the power generation unit 20. The force-guiding member 11 can convert the anisotropic force into the constant force and then transmit the constant force to the driving member 12, and the driving member 12 transmits the mechanical energy to the power generation unit 20 in a stable manner.

The passive sensing device 1 or the passive driving device 100 may further include a housing 40, wherein the force guide 10 is mounted to the housing 40, the driving member 12 is rotatably mounted to the housing 40 about a rotating shaft 13, and the force guide 11 is movably mounted to the housing 40 along a fixed track. The housing 40 may form a receiving cavity 400, wherein at least a portion of the force guide mechanism 10 may be received in the receiving cavity 400, at least a portion of the power generation unit 20 may be received in the receiving cavity 400 of the housing 40, and at least a portion of the communication unit 30 may be received in the receiving cavity 400 of the housing 40, so that the housing 40 may play a certain role in protecting the force guide mechanism 10, the power generation unit 20, and the communication unit 30.

In detail, the force guide 11 is formed with a force guide end surface 1011 at the first end 101, wherein the force guide end surface 1011 can receive forces from at least two directions, such as a forward direction or a lateral direction. The force-guiding end surface 1011 may be a curved surface, such as a hemisphere, a third sphere, etc. Of course, the force-guiding end surface 1011 may be a non-arc surface. The force conducting end surface 1011 may include a first partial force conducting end surface 10111 and a second partial force conducting end surface 10112, the first partial force conducting end surface 10111 and the second partial force conducting end surface 10112 being oriented differently such that the first partial force conducting end surface 10111 may receive forces from at least one direction and the second partial force conducting end surface 10112 may receive forces from at least one other direction, such that the force conducting end surface 1011 may receive forces from different directions.

The housing 40 forms a guide rail 41, wherein the force guide 11 is mounted to the guide rail 41 to be movable back and forth along the guide rail 41. When the force guiding end surface 1011 receives a driving pressure, the entire force guiding member 11 moves toward the driving member 12 to drive the driving member 12, thereby driving the power generating unit 20.

One end of the driving member 12 is pushed by the force guiding member 11, so that the entire driving member 12 can rotate around the rotating shaft 13, and the power generating unit 20 can be driven to move at the other end of the driving member 12.

Further, the force guide 11 may form a driving rail 113, wherein the driving rail 113 is adapted to drive the driving member 12. The driving rail 113 has a driving end surface 1131, and the driving member 12 has a driven end surface 1201, wherein the driven end surface 1201 of the driving member 12 is adapted to be abutted against the driving end surface 1131, so as to drive the driven end surface 1201 through the driving end surface 1131. The force guide 11 can provide a force tangential to the motion trajectory of the driving member 12 to drive the driving member 12 to rotate. It will be appreciated that the force-guiding member 11 itself need not be located tangentially to the path of movement of the driving member 12.

Preferably, the driving end surface 1131 of the driving rail 113 is a cambered surface, and is a cambered surface protruding outwards. Preferably, the driven end surface 1201 of the driver 12 is a curved surface. As the force guide 11 is moved closer to the driving member 12 by an external force, the driven end surface 1201 of the driving member 12 is lifted from a lower position to an upper position along the driving end surface 1131. The driving end surface 1131 of the force guide 11 and the driven end surface 1201 of the driving member 12 are respectively configured as arc surfaces, and may be respectively convex arc surfaces, which may achieve an effect similar to a convex-to-convex effect, so as to facilitate reducing a contact area between the force guide 11 and the driving member 12, and thereby facilitate reducing energy loss during a transmission process.

Further, the driving member 12 may be formed with two driving arms 122, wherein the driving member 12 may include a driving body 121 and two driving arms 122, and the two driving arms 122 are respectively formed to extend outward from the driving body 121. It will be appreciated that the number of drive arms 122 may be one, two or more. The number of drive rails 113 of the force guide 11 can be adapted to the number of drive arms 122 of the drive element 12, for example, two, each drive rail 113 driving one drive arm 122. The driving arm 122 may be formed with a protrusion 123 facing downward at a distal end position, the protrusion 123 may be in the shape of a rotating shaft having an arc-shaped surface, and the driven end surface 1201 is formed on the protrusion 123 of the driving arm 122.

When the force guide 11 moves to just contact the driving member 12, the driven end surface 1201 of the driving member 12 is located at a lower position of the driving end surface 1131 of the force guide 11. With the force guide 11 and the driving member 12 approaching, the driven end surface 1201 of the driving member 12 moves from a lower position of the driving end surface 1131 of the force guide 11 to a higher position of the driving end surface 1131 along the driving end surface 1131, so that the end of the driving member 12 where the driven end surface 1201 is located is lifted, and then the other end of the driving member 12 falls down, so that the power generation unit 20 is driven.

Since at least a portion of the driving arm 122 of the driving member 12 is extended to protrude downward to form the protrusion 123, the protrusion 123 of the driving member 12 can maintain contact with the force guide 11 during the process of lifting the driving member 12 by the force guide 11, so that the mechanical energy from the force guide 11 can be transmitted to the driving member 12 all the time during the process.

Further, the force guiding member 11 may include a force guiding probe 111, a sliding sleeve 112 and the driving rail 113, the force guiding probe 111 is disposed on the sliding sleeve 112, and the sliding sleeve 112 can drive the force guiding probe 111 to move along the guiding rail 41 of the housing 40, and the driving rail 113 is fixedly disposed on the sliding sleeve 112 to move along with the sliding sleeve 112. The force guide probe 111 is used for receiving external acting force, and the force guide end surface 1011 is formed on the force guide probe 111. The force probe 111 is relatively movably mounted to the sliding sleeve 112, for example, the force probe 111 may be rollably or slidably mounted to the sliding sleeve 112 and can receive an external force.

In this embodiment, the force guiding probe 111 is rollably mounted to the sliding sleeve 112, the force guiding probe 111 can be implemented as a roller disposed at one end of the sliding sleeve 112, and the other end of the sliding sleeve 112 is disposed close to the driving member 12. Since the force probe 111 can roll, when the force application object moves to apply a force to the force probe 111, energy can be transferred in the form of rolling friction to reduce energy loss during this process. The sliding sleeve 112 forms a receiving cavity 1120, the driving rail 113 is disposed in the receiving cavity 1120, and at least a portion of the driving member 12 can extend into the receiving cavity 1120.

Furthermore, the force-guiding mechanism 10 of the passive sensing device 1 may further include a force-guiding resetting member 14 and a driving resetting member 15, wherein the force-guiding resetting member 14 is disposed on the force-guiding member 11 for resetting the force-guiding member 11, and wherein the driving resetting member 15 is disposed on the driving member 12 for resetting the driving member 12.

In detail, the force guiding resetting piece 14 is disposed between the housing 40 and the force guiding piece 11, the housing 40 protrudes outward to form a supporting column 42, one end of the force guiding resetting piece 14 is abutted against the force guiding piece 11, and the other end is abutted against the supporting column 42 of the housing 40. When the force guide 11 is pushed to move toward the driving member 12, the force guide resetting member 14 is pressed, and the force guide resetting member 14 accumulates elastic potential energy to reset the force guide 11 in a subsequent step. It is noted that the supporting columns 42 may be positioned and sized such that the force-guiding members 11 are not obstructed by the supporting columns 42 during movement.

The drive return member 15 is provided to the drive member 12. The housing 40 may form a support boss 43, and the drive return member 15 is mounted to the support boss 43 and rotatably mounted to the support boss 43. The rotation shaft 13 corresponding to the driving member 12 may also be mounted to the supporting protrusion 43 such that the rotation axis of the supporting protrusion 43 and the rotation shaft 13 axis of the driving member 12 may be the same rotation axis, so that the driving returning member 15 may return the driving member 12 to the original state.

The force-guiding return element 14 may be a tension spring, which may be compressed or extended in its axial direction. The drive return member 15 may be a torsion spring.

In addition, the driving body 121 of the driving member 12 may form a driving accommodating cavity 1210, wherein the torsion spring may be located in the driving accommodating cavity 1210 of the driving member 12, so that on one hand, the weight of the driving member 12 may be reduced to facilitate driving of the driving member 12, and on the other hand, the driving resetting member 15 may be conveniently accommodated to facilitate reducing the size of the force guide mechanism 10.

Further, the passive sensor device 1 or the passive driving device 100 may further include a follower 50, wherein the follower 50 may be a thin sheet. The follower 50 may be a rigid sheet such as a steel, copper or plastic sheet.

The follower 50 is connected at one end to the driving member 12 and at the other end to the power generating unit 20 to transmit mechanical energy from the driving member 12 to the power generating unit 20.

The follower 50 can serve two functions, one is to increase the power generation efficiency, and the other is to reduce the requirement for the movement speed of the force guide mechanism 10, so that the transmitted mechanical energy can meet the power generation requirement of the power generation unit 20.

Further, the power generation unit 20 comprises a coil set 21 and a magnetic set 22, wherein the coil set 21 and the magnetic set 22 can move relatively to generate electricity by using the principle of electromagnetic induction.

The coil assembly 21 may include a coil 211 and a core 212, wherein the coil 211 surrounds the core 212.

The magnetic assembly 22 may further include a magnet 221 and two upper and lower magnetic conduction members 222, wherein the two magnetic conduction members 222 are respectively disposed on two sides of the magnet 221. A magnetic gap 2220 is formed between the two magnetic conductive members 222, the iron core 212 of the coil assembly 21 extends to the position between the two magnetic conductive members 222 to form the magnetic gap 2220, and when the coil assembly 21 is driven by the follower 50 to move, the iron core 212 can alternately abut against the upper and lower magnetic conductive members 222, so that the magnetic induction lines of the magnetic conductive members 222 with different polarities can alternately act on the iron core 212, and an instant electric pulse is generated in the coil 211 of the coil assembly 21.

It should be noted that the iron core 212 and the magnetic conductive members 222 may be in a contactless engagement, that is, when the iron core 212 moves from one of the magnetic conductive members 222 to the other of the magnetic conductive members 222 and switches between the two magnetic conductive members 222, the iron core 212 does not directly abut against the magnetic conductive members 222, but remains a certain gap with the magnetic conductive members 222, so that noise in the whole power generation process is reduced, and the switching speed between the iron core 212 and the magnetic conductive members 222 can be faster, so that larger energy can be generated.

In this embodiment, the follower 50 is connected to the magnetic assembly 22, for example, can be located between two of the magnetic conductors 222. According to another embodiment of the present invention, the follower 50 may be connected to the coil assembly 21. Alternatively, the follower 50 may not be directly connected to the magnet assembly 22 or the coil assembly 21, but may be indirectly connected to the magnet assembly 22 or the coil assembly 21, so as to achieve the following effect.

It should be noted that the power generation efficiency obtained by simply abutting the iron core 212 of the coil assembly 21 against the magnetic conductive plate of the magnet assembly 22 alternately is very low, and in this embodiment, many measures are taken to improve the power generation efficiency, so that when the passive sensing device 1 is pushed lightly, enough electric energy can be generated to send a signal.

In addition, the driving force of the mechanical passive sensor device 1 is as small as possible, which is desirable for a user that the passive sensor device 1 cannot or is difficult to sense any noise or vibration during the driving process, which requires reducing the driving force of the power generation unit 20 and maintaining the normal operation of the communication unit 30.

The upper and lower magnetic conductors 222 of the magnetic assembly 22 form a magnetic gap 2220, and the height of the magnetic gap 2220, that is, the distance between the two magnetic conductors 222, can be controlled to be between 1.5mm and 3mm, and if it is beyond this range, the operation noise of the power generation unit 20 will become larger, and the operation stroke of power generation will become larger, so that the practicability is poor.

Further, the coil assembly 21 includes the coil 211, the iron core 212, and a magnetism increasing wall 213, wherein one end of the iron core 212 of the coil assembly 21 extends into the upper and lower magnetic conductive members 222 to form the magnetic gap 2220. The magnetizing wall 213 is disposed around the coil 211 to increase the density of magnetic induction lines passing through the coil 211 to increase the power generation efficiency of the power generation unit 20. The walls 213 may be covered on at least one side of the coil 211, or may be two or more sides to facilitate enhancement of the magnetic field strength.

One of the measures to improve the power generation efficiency is to increase the abutment speed between the iron core 212 and the two magnetic conductive members 222 of the magnetic group 22.

The contact switching time between the upper and lower magnetic conductive members 222 between the iron core 212 of the coil assembly 21 and the magnet 221 of the magnet assembly 22 of the power generating unit 20 is controlled to be 0.5 to 10 milliseconds, that is, the contact switching time between the iron core 212 and the upper magnetic conductive member 222 can be controlled to be 0.5 to 10 milliseconds. If it is less than this value, the driving force and driving value required by the power generation unit 20 are significantly increased, and if it is more than this value, the power generated by the power generation unit 20 is weak so that the communication unit 30 of low power consumption cannot be driven.

This switching time can be controlled by optimally designing the sectional area of the core 212, the number of pounds of the coil 211, the height of the magnetic gap 2220, the strength of the magnetic field, the magnetic permeability of the flux increasing wall 213, and the reaction speed of the follower 50. The load power consumption of the communication unit 30 can also be optimally designed, so that the load of the communication unit 30 works with a small current, because according to lenz's law, the change of the current will in turn hinder the speed of the change of the magnetic field, in other words, if the communication unit 30 supplies a large current, the relative movement speed of the magnetic assembly 22 and the coil assembly 21 will be affected, and the switching between the iron core 212 of the coil assembly 21 and the two upper and lower magnetic conductors 222 is difficult to control within 0.5-10 ms.

Further, the length of the iron core 212 extending into the space between the upper and lower magnetic conductive members 222 of the magnetic assembly 22 is set to be not more than 3mm, for example, not more than 2.5mm, and if the distance is exceeded, the power generation efficiency of the power generation unit 20 is disturbed.

It should be noted that the magnetic assembly 22 and the coil assembly 21 of the power generating unit 20 can perform a relative motion at a high speed to generate a pulse power, and the mechanical device for connecting and supporting or driving the magnetic assembly 22 and the coil assembly 21 to perform a relative motion may be, but is not limited to, the above-mentioned force guiding mechanism 10, and may be various, for example, a pivot type driving device, a lever type driving device, an ejection type driving device, a follower type driving device, a linkage type driving device, a rotary type driving device, and the like, which can enable the magnetic assembly 22 and the coil assembly 21 to perform a relative motion, and enable the magnetic induction lines to act on the coil 211 to generate a power.

It is worth mentioning that, since the power generation efficiency of the power generation unit 20 can be improved, the communication unit 30 can transmit encoded data that can be identified by terminal devices such as bluetooth, Zigbee, RF, Lora, Wi-Fi, and the like.

Referring to fig. 5, the operation of the passive sensing device 1 according to the first preferred embodiment of the present invention is illustrated.

When the force guide 11 of the force guide mechanism 10 of the passive sensor device 1 is subjected to a thrust force to move toward the driving member 12, in detail, the force guide probe 111 of the force guide 11 is subjected to an external thrust force, and then drives the driving rail 113 of the force guide 11 to move toward the driving member 12. The end of the driving member 12 close to the driving rail 113 is lifted up and the end close to the power generating unit 20 is moved down to generate power by driving the follower 50 to move the power generating unit 20.

In the process of moving the force guide 11, the force guide resetting piece 14 is pressed, so that in the subsequent process, the force guide resetting piece 14 converts elastic potential energy into kinetic energy to push the force guide 11 to move outwards to reset. In the process of rotating the driving member 12, the driving reset member 15 is pressed to deform, so as to accumulate elastic potential energy, and in the subsequent process, the driving reset member 15 converts the elastic potential energy into kinetic energy to push the driving member 12 to rotate so as to reset to the original position.

The power generation unit 20A is implemented as a piezoelectric power generation device, which may include a piezoelectric ceramic and an elastic metal sheet.

When the force guide 11 is pushed to retract inward, the driving arm 122 of the driving member 12 is lifted, the driving body 121 of the driving member 12 swings downward, and the piezoelectric sheet of the power generation unit 20A is in a pressed-down state.

When the force guide 11 moves outward to protrude, the driving arm 122 of the driving member 12 moves downward, the driving body 121 of the driving member 12 swings upward, and the piezoelectric sheet of the power generation unit 20A is in a lifted state.

It is understood that the power generation unit 20A may also be implemented as, but is not limited to, magnetic abutment type power generation, moving coil type power generation, and magneto generation.

Referring to fig. 8 and 9, the passive sensing device 1 according to the third preferred embodiment of the present invention is illustrated.

In the present embodiment, the force guide 111 of the force guide 11 is implemented as a ball, and in the above embodiments, the force guide 111 is implemented as a roller.

In this embodiment, the force-guiding probe 111 and the sliding sleeve 112 may be fixedly configured, for example, configured with each other by way of integral molding. Of course, it will be understood by those skilled in the art that the force probe 111 and the sliding sleeve 112 may also be fixedly connected to each other by gluing, snapping, etc.

Further, the force guiding end surface 1011 of the force guiding probe 111 is not necessarily a smooth arc surface, and may be concave-convex. Preferably, the force-guiding end surface 1011 is rounded to reduce drag. It is understood that the force probe 111 may be a ball, or a surface with a shape that can reduce the resistance, such as a tongue, a curved surface, or a slant surface.

It should be noted that the force guide 11 can be driven by pressure whether the revolving door is pushed inward or opened outward. That is, forces from different directions may drive the passive sensing arrangement 1.

When the two sliding doors are closed, the assistor 2 can apply pressure to the passive sensing device 1 to drive the passive sensing device 1 to generate power. When the two sliding doors are opened, the pressure applied by the assistor 2 to the passive sensing device 1 disappears, and the compressed force-guiding member 11 can move towards the opening direction, so that the driving member 12 can be driven to rotate, and the power generation unit 20 is driven to generate power, as shown in fig. 13.

Referring to fig. 14, the passive sensor device 1 may be disposed on a side accessible to a handle of a lock, so that the passive sensor device 1 may be linked with the lock to send a signal so that the lock may be known to be locked or unlocked at a terminal.

For example, when a door of a toilet in a hotel is closed, a handle of a lock is rotated to press against the passive sensing device 1, so that the passive sensing device 1 can send a signal to a terminal. After a few hours, the terminal is not able to receive any further signal from the passive sensor arrangement 1, i.e. the user is still inside the toilet after it has been used for a longer period of time. The staff at the terminal can arrange the related staff to check before so as to ensure the safety of the user in the toilet.
