Description

Environment-friendly mechanical battery for lock industry

Technical Field

The invention relates to the field of energy and environmental protection, and belongs to the field of electromechanical equipment. In particular to an environment-friendly mechanical battery suitable for the lock industry.

Background

With the progress of modern science and technology and the importance of society on safety, intelligent locks using electronic technology have become widespread in daily life day by day, and the intelligent locks have the advantages of convenient operation, difficulty in cracking and higher adaptability of life scenes than traditional mechanical locks.

The traditional mechanical lock achieves the purpose of controllable locking by using a low-encryption means of matching the physical shapes of the key and the lock groove, and the method is extremely easy to copy and crack. The intelligent lock adopting the electronic technology can achieve the purpose of controllable locking by combining the uniqueness of human physiological characteristics with the high-strength anti-cracking capability of electronic information encryption and decryption algorithms (such as RSA,3DES, AES, elliptic curve encryption algorithm and the like). Electronic information encryption is a safety foundation in the information age, guards huge information assets far exceeding (millions times) the total value of individual household assets, and is an extremely reliable controllable locking technology.

However, the drawbacks of electronic technology are also apparent. The traditional mechanical lock uses a mechanical structure, external energy supply is not needed, and the door can be opened only by applying force to a key by a user. Electronic locks, which use electronic technology and require external power supply, have a series of hard defects and environmental damages that conventional mechanical locks do not have, such as: 1) battery anxiety problem: when the power supply is insufficient (such as power failure and battery under-voltage), the electronic lock is broken down due to the failure of the electronic equipment. 2) The problem of electrical appliance aging: the circuit is not powered off for a long time, so that the service life of the electronic components is extremely short compared with that of mechanical products. 3) The problem of battery pollution: the power supply device for the lock industry, such as a battery, has great harm to the environment in production, use and scrapping.

Since the last century, extreme phenomena such as acid rain, haze, climate warming, polar crown melting, river channel necrosis, land desertification, forest withering and death, drastic reduction of animals, high incidence of cancers and the like frequently appear, highly developed industries gradually paralysis the self-cleaning capability of the natural environment and indirectly influence the health of human beings. Environmental protection is a sustainable development strategy for industry to form a good balance with human and nature, and is also an urgent need in the era.

Under the background of the current specific times, how to effectively reduce the environmental pollution of various industries becomes a global and general consensus of the whole society. Therefore, the high anti-breaking capability and the high convenience of the electronic encryption technology are considered, the hard defect caused by using electronic devices in the intelligent lock body is overcome, meanwhile, the damage to the environment is reduced, and the problem that the lock industry is extremely core in the low-carbon era is certainly solved.

Disclosure of Invention

In order to at least solve the problems while meeting the intelligent electronization of locks, the invention provides a green and environment-friendly short-time power supply battery scheme. The power supply is characterized in that when torque input occurs, short-time voltage-stabilizing direct current is provided. The composition comprises: the device comprises a power transmission mechanism, a one-way power transmission mechanism, a stroke amplification mechanism, a micro power generation mechanism, a variable voltage and stabilized voltage circuit and an electric storage device.

The technical principle used by the invention is as follows: based on the principle of physical energy conversion, the mechanical energy of input torque acting is directly converted into electric energy. The input torque is enabled to be effective in a single direction (for short acting stroke) through the unidirectional force transmission mechanism, and the reverse idle running (for short reset stroke) of the unidirectional force transmission mechanism is used for resetting the input device. The input torque of the power transmission mechanism is transmitted to the stroke amplification mechanism in an acting stroke through the matching of a gear, the stroke amplification mechanism converts low-speed torque into high-speed torque and acts on the micro generator, the micro generator generates electric energy through the electromagnetic induction principle, the electric energy is converted into voltage-stabilizing direct current through the voltage-changing and voltage-stabilizing circuit, the circuit generates 2 paths of output, the electric energy output 1 is used by an external circuit, and the electric energy output 2 is connected with an electric storage device. The power output 1 is in parallel relation with the power output 2.

[ corresponding feature of the invention for solving the problem of power anxiety ]

To electric quantity anxiety problem, be subject to the physical space restriction when the lock body installation and be suitable for and reform transform the degree of difficulty, the battery power supply mode is mostly adopted to current intelligent lock, for corresponding electric quantity anxiety problem, adopts the mode that reduces circuit standby power consumption, and the chip that uses the standby energy supply that has super low-power consumption is long when extension dry battery or rechargeable battery's power supply, has alleviated electric quantity anxiety problem to a certain extent. But the boundary failure problem of insufficient power is not completely solved, namely: the power is insufficient and the charging period of the power shortage warning is missed, so that the door lock cannot be opened. And partial manufacturers adopt an external charging interface or a mode of internally containing a traditional unlocking structure, so that the problem of boundary failure is solved. These solutions alleviate the battery anxiety to some extent. However, limited by the drawbacks of the solutions, the application of smart locks is currently limited only to application scenarios where the supply of electrical energy is sufficient and the accessories are sufficient, such as homes, commercial stores, etc.

Based on the premise that the invention adopts the physical principle of converting mechanical energy into electric energy, the invention is characterized by corresponding electric quantity anxiety: 1) the power supply principle is changed: replace the electrical storage equipment based on electrochemical reaction with energy conversion equipment, and energy conversion equipment's input is the mechanical energy that very easily obtains from the user, the defect that the electrochemistry performance of no traditional battery naturally reduces along with time, 2) combine the structural design of optimization to change the characteristic of battery power decay, power decay is relevant with the number of times of use, basically not change along with time, and then the safe service life of extension, 3) combine the structural design of optimization, when the power decay takes place, need not contact the battery and reform transform, increase the working stroke and can offset the power decay, and then the safe service life of extension.

Specifically, for the battery of the present invention, charge decay is related to two factors: 1) the demagnetization of the permanent magnet of the generator leads to insufficient electricity generated by the electromagnetic effect, and 2) the mechanical abrasion leads to the reduction of the amplification proportion of the stroke amplification mechanism, thereby leading to insufficient working stroke.

For the first factor of demagnetization, the permanent magnet is resistant to cold and hot, does not generate a natural demagnetization phenomenon, and is easy to generate the demagnetization phenomenon only under the following 4 special conditions. The relevant cases and corresponding solutions are as follows:

1) and (3) high-temperature demagnetization: the mechanical battery of the invention inputs torque with low speed and large force, the connection part with the outside is a force transmission mechanism, the permanent magnet as an isolation object is bonded with an internal structural component (a generator rotor shell) by adopting a high-temperature-resistant adhesive, so that the external temperature has extremely low influence on the temperature of the permanent magnet through the structural connecting piece, and the temperature transmitted by an air medium can be reduced by coating a high-temperature-resistant medium on the surface of the permanent magnet

2) High-frequency impact demagnetization: the external stress of the battery is characterized by low speed and large torsion. When the battery is fixed, the high-temperature resistant flexible gasket can effectively resist high-frequency impact, and the fixing mode is not limited to four-corner concave cavity fixing (without screws) and the like. If the external mechanism has the capability of resisting high-frequency impact, the battery of the invention can be directly fixed by screws

3) And (3) demagnetizing with a high magnetic field: because the battery shell of the invention is sealed by adopting a metal material structural part with good magnetic conductivity, the sealing magnetizer has good sealing magnetism in a magnetic field, when an external strong magnetic field acts on the battery of the invention, most of the magnetic field passes through the shell, and therefore, a high magnetic field with a demagnetization effect can not be formed on the permanent magnet of the internal generator

4) Excessive impurity demagnetization: for the impurity problem of the magnet, the alloy permanent magnet can be produced by adopting modern processes such as hot-pressing thermal deformation, powder metallurgy and the like, the processing process is ensured to be carried out in a vacuum environment, and meanwhile, the surface of the finished product is electroplated to prevent the problem that the impurities are gradually increased due to the oxidation problem in the use process

Meanwhile, the application field of the invention is characterized in that the permanent magnet is used as follows: short-term use and long-term intermittent low-frequency intermittent application. Under the premise, high temperature, high magnetic field and high frequency impact which cause demagnetization do not exist, so that the demagnetization problem is not the main reason of electric quantity attenuation.

The problem that the second factor of the working stroke is insufficient can be solved by increasing the working stroke, specifically, when the electric energy is accumulated by the electric storage device and the electric quantity is attenuated, the electric energy is insufficient due to the attenuation of the battery by adopting a mode of increasing the working stroke, and then the circuit is driven to work by providing enough electric energy. For the present invention, there are two ways to increase the power stroke (for convenience of description, it is assumed that the clockwise direction is the power stroke direction and the counterclockwise direction is the reset stroke direction): a) b) inputting torque according to a rule similar to [ clockwise A degree, anticlockwise A degree, clockwise A degree and anticlockwise A degree … ] under the condition that the input angle is fixed and limited and assuming the maximum stroke angle A, and increasing the working stroke.

For the invention, in a normal use environment, mechanical wear is a main cause of electric quantity attenuation, and because alloy steel such as stainless steel is adopted as a manufacturing material in the battery body, the attenuation period of the mechanical wear is extremely long (the period of the mechanical wear can refer to automobile parts and relevant industry standards), and the attenuation degree of the mechanical wear is closely related to the use frequency and does not have strong correspondence with the use time of a product (the metal corrosion period in a sealing member is extremely long).

[ corresponding features of the invention to solve the problem of appliance aging ]

The intelligent lock as an emerging product really enters the market for about twenty years so far, and is extremely short compared with the history of mechanical locks for nearly thousand years (starting from copper-made Han Dynasty three-spring locks). In terms of safe service life, the copper lock with the collection record certificate can still be normally used for hundreds of years. And the safe service life of the intelligent lock is about 10 years (the mean value of theoretical evaluation values of manufacturers).

Because the market proportion of the existing intelligent lock is low, the application period is short, and the aging problem of the electric appliance does not become a main factor for restricting the development of the intelligent lock. However, with the popularization of intelligent locks, the short service life is a considerable roadblock in the development process.

For the short service life of the circuit, the conventional intelligent lock product adopts an uninterruptible circuit operation mode for various reasons, which accelerates the aging of the circuit and can be called as a main factor influencing the service life. Moreover, the electric products are updated quickly, which further reduces the service life thereof. The result is that the figure of the intelligent lock is rarely found in the scene with long application period. In other words, the application of smart locks has not been found in devices/equipment designed to last more than 10 years.

For the problem of circuit aging, in terms of electrical engineering, except that electronic components (such as electrolytic capacitors) containing liquid volatile chemical substances can naturally attenuate or even fail, other electronic components or circuit boards mainly cause electrical appliance aging due to the following reasons:

1) the current passes through the conductor to heat it, so that the metal is oxidized quickly to deform the conductor and change the resistance

2) The metallic material forms a surface film at the electrical contact, which makes the resistance change even insulating (this reason has a great influence on the weak current system)

3) The metal oxide can generate electrochemical reaction (such as copper-tin oxide) in electrified state, thereby accelerating element oxidation, causing resistance change and even insulation

In order to solve the problem of aging of the electric appliance and prolong the service life of the circuit of the intelligent lock, the invention adopts a power supply mode according to the requirement to reduce the running time of the circuit. When no input torque exists, the circuit is in a power-off stop state. In short, the invention is characterized by the aging problem of the electric appliance: the power is supplied according to the requirement, and the electric energy is not supplied when no torque is input. The following computational example outlines the differences between conventional non-intermittent power supply and the on-demand power supply of the present invention.

The difference between the traditional power supply and the power supply of the invention is as follows by taking the product use for 1 week as a test period and the same circuit mainboard as a test object:

1) the circuit load time in the conventional power supply (7 × 24 non-intermittent power supply) mode is:

to = 7 days 24 hours 3600 seconds = 604,800 (seconds)

2) The circuit load time using the present invention (on-demand power mode) is:

tn = 7 days 10000 times 1 second = 70,000 (seconds)

Wherein 10000 times is the number of door opening times per day, and 1 second is the time of circuit operation when opening door each time

3) The ratio of the two is about:

s = To/Tn = 8.628 (times)

Namely: compared with the traditional power supply mode, the power supply mode of the invention shortens the working time of the electronic zero device by about 8.63 times, and theoretically prolongs the working life by about 8.63 times.

Obviously, by adopting the mode of supplying power according to the requirement, the intelligent lock circuit can obtain extremely long safe service life only by avoiding the use of electrolytic capacitor elements.

[ corresponding characteristics of the invention to environmental protection problems ]

The problem of battery contamination is essentially an environmental issue. For the environmental protection problem of solving the attention of this time, a large amount of intelligence lock products use rechargeable lithium cell to reduce carbon and discharge, reduce the environmental pollution of use, simultaneously, through the service life of extension battery, reduce and scrap the number of times in order to reduce the abandonment and pollute. On the premise that the raw material proportion structure of an actual power supply system is not substantially changed, particularly the proportion of thermal power generation is high, the charging mode does not meet the expected environmental protection expectation, the change only indirectly solves the environmental protection problem during the use of the battery in the product per se, the ring pressure maintaining force is transferred to the power supply mechanism, and the environmental influence is not really solved. Also, the rechargeable battery does not solve the problem of environmental pollution when discarded.

For practical straight-face environmental influence, the invention is characterized by corresponding environmental protection: 1) replacing the raw materials which are not easy to recover by the pollution-free raw materials which are easy to recover; 2) replacing the electrochemical reaction-based power supply mode with a physical principle-based power supply mode; 3) replace the short safe age design with a long safe age design.

Specifically, the environmental protection effect is estimated by using a quantitative simulation method, which can be referred to as follows:

1) 13 million people nationwide, assuming a total of 3 million households and a total of 3 million locks. (Do not consider shop door, vehicle door, anti-theft cabinet door, etc.)

2) The power supply mode is unified according to 8 dry batteries (12V), and the batteries are replaced once a year. (the pollution of the rechargeable battery is higher than that of the dry battery under the condition of high proportion of thermal power generation)

3) The universality of the intelligent lock is calculated by 30 percent, about 1 hundred million intelligent locks and about 8 hundred million dry batteries in annual loss

4) The average service life of the circuit is determined by referring to the safety life of a uninterruptible electric appliance (refrigerator), and the safety life of the traditional intelligent lock is temporarily set to be 12 years. After the battery is adopted, the service life of the intelligent lock is about 100 years (8.36 times in 12 years), and the temporary safety life is 70 years in combination with the practical application scene

5) The battery of the invention can save manufacturing materials, processing pollution and waste pollution of 8 hundred million dry batteries every year

6) The property age of a building is taken as an evaluation period, the pollution of 560 hundred million dry batteries is avoided in one period, assuming that a door lock is replaced once in 12 years and is not replaced 5 times in 70 years, namely the production and use of 5 hundred million circuit boards are reduced, and one hundred million recyclable all-metal products are left after one period.

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

[ POWER TRANSFER MECHANISM ]

The force transmission mechanism is also called a three-section asynchronous force transmission mechanism and comprises a hollow shaft sleeve 1001, a hollow gear column 1002 and a hollow shaft sleeve 1003, wherein the hollow parts of the three parts are square holes with the same size, and the inner end surface of each shaft sleeve groove is attached to the upper end surface and the lower end surface of the hollow gear column. During rotation, no external force is axially applied, and the hollow gear column is driven to rotate by torque force. The method is characterized in that: 1) the three-section design is beneficial to adopting materials made of different materials, so that the force transmission mechanism has the characteristics of wear resistance and large torque. 2) When the battery is used as an embedded component, the battery is beneficial to the difference output effect generated by the force application of the front lock handle and the force application of the rear lock handle.

[ ONE-WAY TRANSFER MECHANISM ]

The unidirectional force transmission mechanism is composed of a fixed shaft 2001, a fixed guide shaft 2002, an upper fixed plate 2003, a lower fixed plate 2004, a transmission gear 2005, a transmission gear shaft guide rail groove 2006, a clamp spring 2007 and a rotating shaft 2008, wherein the transmission gear 2005 is in gear fit with the hollow gear column 1002 and is used for unidirectional transmission of input torque. The fixing

plates

2003 and 2004 are tightly fitted with the fixing shaft 2001, the fixing guide shaft 2002, and the rotation shaft 2008. The transmission gear 2005 is loosely fitted with the fixed guide shaft 2002. The method is characterized in that: 1) high load, 2) unidirectional force transmission, and 3) fusing protection.

The specific principle is that when the hollow gear column 1002 applies force in the working stroke, the component force of the acting force of the transmission gear 2005 enables the hollow gear column 1002 to be tightly attached to the hollow gear column, and the hollow gear column 1002 and the transmission gear enter a self-locking and attaching state. When a force is applied in a reset stroke, the shaft (2002) of the transmission gear 2005 is far away from the hollow gear column 1002 along the transmission gear shaft guide rail groove 2006 around the rotating shaft 2008, and therefore the gears of the two are disengaged from each other to be invalid.

The one-way force transmission mechanism is used as a connecting pivot between the torque input mechanism and the stroke amplification mechanism, and has the specific functions of:

1) the unidirectional force transmission mechanism is beneficial to the reset of the force transmission device. When the mechanism does not exist, the high-speed rotation at the output tail end of the stroke amplification mechanism directly acts on the rotor of the micro generator, the rotor of the generator has relatively large mass, and then when the working stroke and the reset stroke are switched due to the high-speed inertia torque, great critical impact force is generated, so that the force transmission device cannot be reset. And because the transmission of torque is not intercepted in the reset stroke, a large external force is required to be applied to the reset stroke. When the mechanism exists, in the reset stroke, because the input mechanism is in a no-load idle state, the force transmission device can be reset only by small elastic force

2) The unidirectional force transmission mechanism is used for self-destruction protection. The hand can not accomplish at the uniform velocity linearity to the control of moment, and in the use, the violent rotation appears in inevitable, even destructive high-speed violent input, and the one-way power transmission mechanism of high load here chooses the metal (for example copper) of certain hardness, gives consideration to the high load capacity of biography power simultaneously, when encountering destructive input, protects other higher machinery of relative value and battery pack with self damage (broken tooth) and does not receive the influence of destruction, has fabulous explosion-proof guard action to whole device. For the purpose of protection, the gear 1002 of the torque input mechanism, the gear 2005 of the high-load unidirectional force transmission mechanism and the input gear 3001-01 of the stroke amplification mechanism are supposed to be matched by materials (steel teeth: copper teeth: steel teeth). When the torque input mechanism rotates violently at a high speed, the copper teeth are broken due to the hardness of the material, the input gear of the stroke amplification mechanism at the lower stage is not affected by the damage, and the protection effect of 'fusing' similar to that of a circuit fuse is further achieved

In addition to the above-described preferred embodiment, as a less preferred implementation method, in the composition structure, a one-way bearing (also called overrunning clutch) may be used instead of the components other than the fixed guide shaft 2002 and the transmission gear 2005 in the above-described structure. After simplification, the one-way force transmission mechanism consists of a fixed guide shaft 2002, a one-way bearing, a force bearing gear and a transmission gear 2005. The inner cylindrical surface of the one-way bearing is tightly matched with the fixed guide shaft 2002 through a hole shaft, the outer cylindrical surface of the one-way bearing is tightly matched with the force bearing gear through the hole shaft, the force bearing gear is matched with the hollow gear column 1002 through a gear, and the transmission gear 2005 is tightly matched with the fixed guide shaft 2002 through the hole shaft.

[ Stroke enlarging mechanism ]

The stroke amplification mechanism is of great importance in the solution according to the invention, the transmission ratio of which lies between 1:40 and 1:60, and accordingly all components (force transmission mechanism, unidirectional force transmission mechanism, stroke amplification mechanism, generator gear) which participate in the stroke amplification within the structure of the exemplary embodiment form a large-ratio acceleration gear combination of 1:120 to 1: 180. Within this ratio range, the battery of the present invention has the best experience of rotational forcing. When the torque is less than 1:120, the rotation angle of the torque exceeds 90 degrees; when the ratio is more than 1:180, the spring is opened by applying force to an adult.

The stroke amplification mechanism consists of a speed change gear combination 3001 and a transmission gear 3002, wherein an input gear 3001-01 and a rotating shaft 2008 of the gear acceleration box are loosely matched through hole shafts, and when the design value of the transmission ratio of the speed change gear combination 3001 is within 1: 40-1: 60, the stroke amplification mechanism is characterized in that: 1) the device has comfortable force application experience, 2) reasonable force application time (aiming at the same stroke), 3) smooth force application intensity change, and 4) high-quality rotation angle.

Less preferably, a planetary gear arrangement can be used within the gear acceleration housing to carry a greater torque.

[ MINI-GENERATING MECHANISM ]

The micro-power generation mechanism consists of a generator 4001 and a gear 4002, and the gear 4002 is tightly matched with a central shaft of a rotor of the generator through a hole shaft. Gear 4002 is geared with drive gear 3002. The rotation of the transmission gear 3002 drives the gear 4002 to rotate, and the gear 4002 drives the generator rotor to synchronously rotate, so that electromotive force is generated under the action of electromagnetic induction.

The micro generator used by the invention adopts a 3-phase 6-stage 9-slot generator, and has the advantages that: 1) the resultant torque of each slot diamagnetic force of the three-phase 6-stage 9-slot motor to the rotor is relatively stable and uniform during rotation, and 2) the manufacturing process is mature, and the motor has stable performance and high output power. 3) The carbon brush-free structure has no electric spark in the using process.

[ VOLTAGE-TRANSFORMING AND VOLTAGE-STABILIZING CIRCUIT ]

The voltage transformation and stabilization module is composed of a three-phase rectification module and a DC-DC voltage reduction and stabilization module 5002, the three-phase rectification module is an on-sale three-phase rectification module, the three-phase output of the micro generator is connected with the three-phase input of a three-phase rectification bridge, and the positive and negative output of the three-phase rectification bridge is connected with the input positive pole (5002-01) and the input negative pole (5002-02) of the DC-DC voltage reduction and stabilization module 5002. The output positive electrode 5002-03 and the output negative electrode 5002-04 of the voltage reduction module 5002 are connected with the positive electrode and the negative electrode of an external load.

The voltage transformation and stabilization circuit used by the invention comprises a three-phase bridge rectification circuit and a DC-DC voltage reduction and stabilization circuit, and is characterized in that: 1) adaptive input voltage and wide voltage safety range (5-50V), 2) stable output voltage, and 3) small power loss in the conversion process

[ electric storage device ]
