In addition, the friction nano generator is included in the coded lock provided by the embodiment of the invention, and the friction nano generator can collect low-frequency mechanical energy and convert the low-frequency mechanical energy into electric energy, so that the coded lock can collect energy generated at a key, convert the energy into electric signals and transmit the electric signals out, provide electric energy for opening or closing a switch structure, and simultaneously provide electric energy for the operation of a control module, thereby completing unlocking operation, realizing self-driving, solving the problem of battery endurance, saving the volume and weight occupied by a battery, and enabling the coded lock to be smaller and lighter.
Optionally, in an embodiment of the present invention, the external force applied to the friction nano-generator may be: the pressure applied when the user presses the key with the finger or the pressure applied when the user presses the key with the tool; the tool used by the user may be any tool that can press a key, and is not limited herein.
Specifically, when a user presses a key, pressure is applied to the key, and the pressure acts on the friction nano generator, so that the friction nano generator generates an electric signal and transmits the electric signal to the control module, and the control module can control the switch structure to be turned on or turned off according to the electric signal.
Optionally, in an embodiment of the present invention, the control module is specifically configured to:
determining a key corresponding to the friction nano generator outputting the electric signal;
determining the input sequence of each key;
judging whether the determined input sequence is the same as a preset sequence;
if the two types of the control switch structures are the same, the control switch structure is controlled to be started;
if the two types of the control switch structures are different, the control switch structure is closed.
That is, the control module compares the sequence of each key of the output electric signal with a preset sequence when determining the sequence;
if the input password is the preset password, the switch structure can be started at the moment to finish the unlocking process;
if the input password is different, the input password is not the preset password, and at the moment, the switch structure can be kept closed, and the unlocking fails.
The preset sequence may be set according to a user's requirement, which is not limited herein.
Therefore, the control module can unlock based on the received electric signal, the unlocking process of the coded lock is realized, and meanwhile, the safety of the coded lock can be ensured.
Specifically, in the embodiment of the present invention, as shown in fig. 1, a plurality of keys are provided, and each key is connected to the control module 20 through signal lines (e.g., S1, S2, S3, S4, S5, S6, S7, S8, S9, and Sk);

The unlocking process of the coded lock is described below with reference to specific embodiments.
In combination with the key arrangement schematic diagram shown in fig. 1.

if the preset sequence is 3, 5 and 7, the control module 20 can control the switch structure 30 to be opened to complete unlocking;
if the predetermined sequence is not 3, 5, and 7, the control module 20 may control the switch structure 30 to remain closed, failing to unlock.
Optionally, in an embodiment of the present invention, the input panel further includes: the packaging layer is positioned at the outermost side;
the thickness of the encapsulation layer is 100 μm to 200 μm.
For example, as shown in fig. 2, where 11 denotes an encapsulation layer, and the thickness of the encapsulation layer 11 is denoted by d 1.
Therefore, the packaging layer is arranged, so that the keys in the input panel can be packaged, and the keys are prevented from being damaged by the outside; moreover, through the thickness of the packaging layer, the pressure applied by a user can well act on the friction nano generator, particularly when the friction nano generator is of a single-electrode structure, induced charges can be better generated by the friction nano generator, the friction nano generator can well sense touch of fingertips of the user, and further the output electric signal is favorably improved, misjudgment of a control module caused by small difference between the electric signal and an interference signal is avoided, and therefore the control accuracy can be improved.
On the basis, when the friction nano generator is set, the following setting modes can be included:
mode 1:
optionally, in an embodiment of the present invention, the friction nano-generator is a friction nano-generator with a single electrode structure;
the friction nano-generator comprises: and the conducting layer and the friction layer are laminated, and the packaging layer is multiplexed into the friction layer.
Namely: the encapsulation layer is part of the friction nano-generator.
For example, as shown in fig. 2, taking the friction nano-generator 2a included in the key "2" as an example, D0 represents a conductive layer, C0 represents a friction layer, and the friction layer C0 may also serve as the encapsulation layer 11 at the same time.
Therefore, the hierarchical structure of the input panel can be reduced, the manufacturing process of the input panel can be simplified, the manufacturing cost is reduced, the thickness of the input panel can be reduced, and the design of lightening and thinning of the coded lock is realized.
Optionally, in an embodiment of the present invention, the conductive layer may be made of a material including: a solid or liquid conductive material;
wherein the solid electrode material may include: conductive metal films, conductive polymer materials, and the like;
the conductive metal film may include: conductive copper films, conductive aluminum films, and the like;
the conductive polymer material may include: polyacetylene, polypyrrole, polyaniline, and the like;
the liquid conductive material may include: silver nanowires, conductive copper paste, conductive silver paste, and the like.
Optionally, in an embodiment of the present invention, the friction layer may be made of a material including: a liquid packaging material or a solid film material;
wherein the liquid packaging material may comprise: liquid paint substances such as amino paint, acrylic paint, polyurethane paint and the like;
the solid film wrapper may comprise: dyed polyvinyl chloride, polytetrafluoroethylene, polydimethylsiloxane, and the like.
Of course, in the implementation, the materials for manufacturing the conductive layer and the friction layer are not limited to the materials given above, but may be other materials known to those skilled in the art that can perform the functions of the conductive layer and the friction layer, and are not specifically limited herein.
Alternatively, in the embodiment of the present invention, when the friction nano generator is a friction nano generator of a single electrode structure, the conductive layer is grounded through a load.
At this time, when the user's fingertip presses the key, a current is generated between the conductive layer and the ground, and an electrical signal is output.
Specifically, when the friction nano-generator is a friction nano-generator with a single electrode structure, the working process of the friction nano-generator may include:
taking the working mode of the friction nano generator as a contact-separation example, the basic working principle of the friction nano generator is as follows: contact electrification and electrostatic induction.
When a finger tip of a user presses a key in an input panel, the finger tip is contacted with the surface of the key, surface charge is transferred between the friction layer and the electrode layer due to surface charging effect caused by contact, and a potential difference is generated, and when the friction layer has good insulation and is contacted with the conductive layer, electrons can migrate out of the conductive layer under the action of the potential difference, so that an electric signal is formed and output.
Mode 2:
optionally, in an embodiment of the present invention, the friction nano-generator is a friction nano-generator with a single electrode structure;
the friction nano-generator comprises: a conductive layer and a friction layer which are laminated;
the friction layer is positioned between the conductive layer and the encapsulation layer.
Namely: the packaging layer and the friction nano-generator are of two different structures, and the packaging layer is not part of the friction nano-generator.
For example, as shown in fig. 3, taking the friction nano-generator 2a included in the key "2" as an example, D0 represents a conductive layer, C0 represents a friction layer, and 11 represents an encapsulation layer, wherein the friction layer C0 and the encapsulation layer 11 have different structures, that is, the encapsulation layer 11 is not multiplexed into the friction layer C0.
Therefore, after each friction nano generator is manufactured, the packaging layer is manufactured, so that when the input panel is impacted or impacted by the outside, the friction nano generator can be well protected through the packaging layer, the friction nano generator is prevented from being damaged, and the service life of the coded lock is prolonged.
And the position of the friction nano generator can be well hidden, so that the position of the key is hidden, and the overall safety of the coded lock is further improved.
Specifically, in this mode 2, the arrangement of the materials for manufacturing the conductive layer and the friction layer, and the operation principle of the friction nano-generator can be referred to the embodiment in mode 1 described above, and will not be described in detail.
Mode 3:
optionally, in an embodiment of the present invention, the friction nano-generator is a friction nano-generator with a double-electrode structure;
the friction nano generator is encapsulated inside the input panel by the encapsulation layer.
Namely: the packaging layer and the friction nano-generator are of two different structures, and the packaging layer is not part of the friction nano-generator.
For example, as shown in fig. 4, the encapsulation layer 11 encapsulates the friction nano-generator 2a and the friction nano-generator 3a inside the input panel.
Therefore, after each friction nano generator is manufactured, the packaging layer is manufactured, so that when the input panel is impacted or impacted by the outside, the friction nano generator can be well protected through the packaging layer, the friction nano generator is prevented from being damaged, and the service life of the coded lock is prolonged.
Alternatively, in the embodiment of the present invention, as shown in fig. 5, the friction nano generator (for example, 2 a) includes: a first friction structure m1 and a second friction structure m2;
wherein the first friction structure m1 includes: the first conductive layer D1 and the first friction layer C1 are arranged in a stacked manner, and the first friction layer C1 is positioned between the first conductive layer D1 and the second friction structure m2;
the second friction structure m2 includes: the second conductive layer D2 and the second friction layer C2 are stacked, and the second friction layer C2 is located between the second conductive layer D2 and the first friction structure m 1.
A certain gap exists between the first friction structure m1 and the second friction structure m2 (as shown by d2 in fig. 5).
Therefore, when the finger tip of a user presses the key, the first friction layer and the second friction layer are contacted and separated under the action of external force, and the electric signal is transmitted through the first conductive layer and the second conductive layer.
Specifically, in this mode 2, the arrangement of the first conductive layer, the second conductive layer, the first friction layer, and the second friction layer can be referred to the embodiment in mode 1 described above, and detailed description thereof will be omitted.
In other words, in the implementation, when the friction nano generator is provided, the above-described modes 1, 2 and 3 may be selected according to actual needs, and the arrangement is not limited thereto.
Alternatively, in the embodiment of the present invention, as shown in fig. 4, the thickness d3 of the friction nano-generator is 10 μm to 30 μm.
Wherein in particular the thickness d3 of the friction nano-generator may be 20 μm.
Therefore, the friction nano generator has a proper thickness, the volume of the coded lock is prevented from being increased due to the fact that the coded lock has a large thickness, meanwhile, the friction nano generator can be enabled to generate an electric signal easily, keys are enabled to be triggered easily, and operability of the coded lock is improved.
Optionally, in an embodiment of the present invention, as shown in fig. 2 to 4 and fig. 6, the input panel further includes a substrate 12;
the friction nano-generator is disposed over a first surface (denoted B1) of the substrate 12, and the outermost surface (denoted Bw) of the input panel is a flat surface;
wherein the friction nano-generator is located between the first surface B1 and the outermost surface Bw.
So for the outermost surface (namely the surface that can touch when the user presses the button) of input panel is flat and smooth surface, the button can not outstanding in the outermost surface, namely just hide the button in the input panel inside promptly for the button has better disguise, and just is difficult to judge the position of button through observing, makes the trick lock safe and reliable more.
Specifically, on this basis, when the position of the friction nano generator is set, the following cases may be included:
case 1: and (5) embedding.
Alternatively, in the embodiment of the present invention, as shown in FIG. 6, the first surface B1 is provided with a groove 12-1; the friction nano generator is a friction nano generator with a single electrode structure, and the friction nano generator comprises: a conductive layer D0 and a friction layer C0 which are laminated;
the conductive layer D0 is located in the groove 12-1, the friction layer C0 covers at least the conductive layer D0 and the area Q1 of the first surface except the groove 12-1, and a side surface of the friction layer C0 facing away from the conductive layer D0 is the outermost surface Bw.
In this connection, it is explained that in fig. 6, two grooves 12-1 are shown, and in order to make it possible to see the grooves 12-1 clearly, only the conductive layer D0 is shown in one of the grooves 12-1, but this does not mean that the conductive layer D0 is not provided in the other groove 12-1, and in particular, the conductive layer D0 is provided in each groove 12-1.
That is, when the friction nano generator is a friction nano generator with a single electrode structure, the conductive layer can be arranged in the groove, and meanwhile, the friction layer can be reused as the packaging layer, so that the friction layer can realize the function of friction electrification and simultaneously realize the packaging function, and the conductive layer is protected.
And, because the first surface of basement is provided with the recess, and the conducting layer sets up in the recess, can make input panel's overall thickness reduce, and then make input panel frivolous more, thereby realize the frivolous design of trick lock.
Alternatively, in the embodiment of the present invention, a plurality of grooves 12-1 may be provided, and each groove 12-1 corresponds to one key (only the conductive layer D0 is shown as a corresponding key in the drawing), that is: the grooves 12-1 are arranged in one-to-one correspondence with the keys, as shown in fig. 6;
at this time: when the area of the groove is substantially the same as the area of the conductive layer, the friction layer is disposed substantially outside the groove, and the friction layer covers the conductive layer and the area of the first surface other than the groove.
Illustratively, when a gap exists between the recess and the conductive layer, the encapsulation layer may fill the gap.
Thus, the friction layer can be reduced, and the outermost surface of the input panel can be ensured to be a flat surface more easily.
Or when a plurality of grooves are provided, each groove can correspond to a plurality of keys, that is, the grooves and the keys are in one-to-many relation, and illustration is not given;
at this time: the friction layer is required to cover not only the conductive layer and the region of the first surface except for the grooves, but also the region of the grooves not occupied by the conductive layer.
Therefore, the number of grooves can be reduced, the manufacturing difficulty of the input panel is reduced to a certain extent, and the manufacturing cost is reduced.
Or, only one groove is provided, and the groove corresponds to all keys, namely, one groove accommodates all keys, and illustration is not given;
at this time: the friction layer is required to cover not only the conductive layer and the region of the first surface except for the grooves, but also the region of the grooves not occupied by the conductive layer.
Therefore, the number of grooves can be effectively reduced, the manufacturing difficulty of the input panel is effectively reduced, and the manufacturing cost is effectively reduced.
Of course, in the concrete implementation, when the grooves are set, the grooves can be set according to actual needs, so that the flexibility of design is improved, and the requirements of different application scenes are met.
Specifically, taking a friction nano-generator with a single electrode structure as an example, the manufacturing process of the friction nano-generator may include:
arranging a certain number of grooves on the random position of the first surface of the substrate, coating and placing conductive metal paste at the grooves, and performing external wiring treatment when the conductive metal paste is not completely dried;
after the conductive metal paste is completely dried, acrylic paint (which can be used as a friction layer or a packaging layer) is attached to the first surface of the whole substrate, so that the whole surface is smooth and uniform, and the friction nano generator with a single electrode structure is formed.
Therefore, the appearance of the coded lock can be smooth and uniform, and the key positions are in a completely concealed state.
Case 2: and (3) an external device.
Alternatively, in an embodiment of the present invention, as shown in fig. 2 to 4, the friction nano-generator is located above the first surface B1;
the input panel further comprises a planarization layer 13, wherein the planarization layer 13 covers the exposed first surface B1 and the friction nano-generator (e.g. 2a and 3 a), and a side surface of the planarization layer 13 facing away from the friction nano-generator is an outermost surface Bw of the input panel.
Thus, the first surface can be prevented from being grooved, the grooving process is reduced, the manufacturing process of the input panel is simplified, and the manufacturing cost is reduced.
Specifically, when the friction nano-generator is a friction nano-generator of a single electrode structure, the friction layer C0 may be multiplexed as the planarization layer 13 as shown in fig. 2, or the encapsulation layer 11 may be multiplexed as the planarization layer 11 as shown in fig. 3; in fig. 2, the friction layer C0 may be multiplexed as the encapsulation layer 11 or the planarization layer 13;
alternatively, when the friction nano-generator is a dual electrode structure friction nano-generator, the encapsulation layer 11 may be multiplexed as the planarization layer 13, as shown in fig. 4.
That is, regardless of the structure of the friction nano-generator, when the friction nano-generator is located above the first surface, it is necessary to fill the friction nano-generator with a planarization layer, so that the outermost surface of the input panel is a flat surface, thereby improving the concealment of the key arrangement.
Specifically, taking a friction nano-generator with a single electrode structure as an example, the manufacturing process of the friction nano-generator may include:
and directly adhering a conductive metal film on the first surface of the substrate, performing external connection treatment, and coating acrylic paint (serving as a friction layer and a flattening layer) on the whole first surface to enable the whole plane to be flat and smooth, and hiding the position of the conductive metal film to form the friction nano generator with a single electrode structure.
Therefore, the appearance of the coded lock can be smooth and uniform, and the key positions are in a completely concealed state.
In short, in the actual case, when the friction nano generator is provided on the substrate, the above case 1 or case 2 may be adopted, and the arrangement may be specifically performed according to the actual need, which is not limited herein.
Optionally, in an embodiment of the present invention, the control module may include: a microcontroller or a processor.
Optionally, in an embodiment of the present invention, the switch structure may include: a mechanical lock cylinder or other similar structure.
Optionally, in the embodiment of the present invention, the combination lock may include other structures for implementing the function of the combination lock in addition to the above structures, which will not be described in detail herein.

s701, receiving an electric signal output by the friction nano generator under the action of external force;
s702, controlling the switch structure to be opened or closed according to the electric signal.
In one point, the execution subject of the two steps S701 and S702 may be a control module.
Optionally, in an embodiment of the present invention, the switch structure is controlled to be turned on or off according to the electrical signal, which specifically includes:
determining a key corresponding to the friction nano generator outputting the electric signal;
determining the input sequence of each key;
judging whether the determined input sequence is the same as a preset sequence;
if the two types of the control switch structures are the same, the control switch structure is controlled to be started;
if the two types of the control switch structures are different, the control switch structure is closed.
Optionally, in the embodiment of the present invention, when a plurality of keys are provided and each key is connected to the control module through a signal line, determining an input sequence of each key specifically includes:
and determining the input sequence of the keys outputting the electric signals according to the signal lines corresponding to the received electric signals and the preset corresponding relation between the signal lines and the keys.
Alternatively, in the embodiment of the present invention, the above-mentioned coded lock may be applied to a residence and a safe, and may also be applied to other scenarios, such as, but not limited to, mechanical devices, a vehicle fuel tank, and a vehicle protection door, etc., which are not limited herein.
For example, if the coded lock provided by the embodiment of the invention is used for a safe, when the fingertip of the user contacts with the key of the coded lock and presses the corresponding key, the control module can control the safe according to whether the electric signal output by the input code accords with the preset code sequence of the user; if the input password accords with the preset password sequence, the party can open the safe; if the input password does not accord with the preset password sequence, the operation of opening the safe is not executed.
In the embodiment of the invention, the friction nano generator is directly used as the key of the coded lock, and when the friction nano generator is of a single electrode structure, the advantages of simplicity, light weight, small size and convenience of the single electrode structure can be fully utilized; compared with the traditional coded lock, the coded lock can better hide the positions of the keys, disorder the traditional rules of key arrangement and enhance the overall safety; in addition, the coded lock has the advantages of simplicity and convenience in operation, low cost, simplicity in manufacturing process, environment friendliness and the like, can be combined with programs in external equipment (such as mobile phones, tablet computers, notebook computers, desktop computers and the like) while improving the safety anti-theft function, is convenient and quick to use, and ensures property safety of users.
