Description

Technical Field

[0001] The present invention relates to the field of password equipment, and in particular to a rotary disk password input structure and an input method thereof. Background Art

[0002] Most of the current passwords use a flat password keyboard as a means of password input, and some use up, down, left, and right keys. This method divides the password input area into several small blocks, greatly reducing the structural strength of the input surface. The key input panel is easily damaged and is not suitable for use in scenarios with high security requirements. Therefore, the use of an integrated rotary disk electronic password input method can greatly improve the anti-riot strength from a structural perspective, and is suitable for use in products with high protection requirements, such as electronic locks, electronic password boxes, and other fields. Summary of the invention

[0003] In response to the problems and needs raised above, this solution proposes a rotary dial password input structure and input method thereof, which can achieve the above technical objectives and bring about many other technical effects by adopting the following technical features.

[0004] An object of the present invention is to provide a rotary disk type password input structure, comprising:

[0005] The turntable has password marks arranged at equal intervals along its circumferential direction and on its first end surface, wherein the interval angle between two adjacent password marks is a first specified angle;

[0006] A metal spring sheet, fixedly connected to a second end surface of the rotating disk away from the first end surface, and the metal spring sheet has a plurality of contact angles;

[0007] A PCB circuit board is relatively pivotally connected to one side of the metal spring sheet where the plurality of contact angles are arranged, and a plurality of contact points are distributed in a circumferential direction of the PCB circuit board; wherein the plurality of contact points are respectively arranged in a password contact area and a wake-up contact area;

[0008] When the turntable rotates a first specified angle or a multiple of the first specified angle, the metal spring contacts and conducts with the plurality of contact points in the password contact area, so that the PCB circuit board is switched on and off to realize the code recognition of the password mark on the turntable.

[0009] In the technical scheme, the working process of the input structure is as follows: first wake up the PCB circuit board circuit, then rotate the turntable along the first direction to the first password contact area, then rotate the turntable along the second direction opposite to the first direction to the second password contact area, and at the same time make the PCB circuit board enter the working state and identify the first password; rotate the turntable along the first direction again to the third password contact area, and at the same time make the PCB circuit board enter the working state and identify the second password; and so on, repeat the above steps to realize the input of multiple passwords, when the turntable rotates to the last password contact area, the turntable is rotated in the opposite direction to exceed the angle of one password contact area and stays, so that the last password is recognized. The structure of the input structure is simple, by printing contact points on the PCB, the password turntable and the metal spring are clamped together, and the password is rotated to the indicated point password contact area to realize the password input. The structure is simple and firm, not easy to be violently destroyed, and has an anti-peeping function (keyboard passwords are very easy to be peeped during the input process). It is small in size and does not need to scramble the password after input like a multi-digit mechanical password. It can completely replace the mechanical password and has all the functions of the electronic password.

[0010] In addition, the rotary disk password input structure and input method according to the present invention may also have the following technical features:

[0011] In one example of the present invention, the metal dome includes:

[0012] The main body is provided with a connecting hole, which is adapted to the rotating shaft provided on the rotating disk;

[0013] A contact angle is formed on a side of the main body portion close to the PCB circuit board, and under the action of elastic deformation, the contact angle has an elastic force that always resists the PCB circuit board. It is configured to contact and conduct with the contact points of the password contact area or the wake-up contact area after synchronously rotating with the turntable at a first specified angle or a multiple of the first specified angle, a second specified angle or a multiple of the second specified angle, so as to realize the code recognition of the password mark on the turntable or the circuit wake-up of the PCB circuit board.

[0014] In one example of the present invention, the contact angle is formed by a bending process at one end away from the main body, wherein the bent portion of the contact angle forms a protruding point, and the protruding point is abutted against a contact point of the PCB circuit board.

[0015] In one example of the present invention, the contact angle comprises: a plurality of coding antennae,

[0017] In one example of the present invention, the coding antenna is located on a circle with the center of the connecting hole as the center and the distance from any one of the coding antennas to the center as the radius, wherein the distances from multiple coding antennas to the center include at least two different radius distances.

[0018] In an example of the present invention, the number of the coding antennae at each position on the main body portion includes two, and the two coding antennae are arranged in parallel.

[0019] In one example of the present invention, the contact angle further includes: a wake-up feeler,

[0020] It is suitable for stopping at a contact point of the awakening contact area of ​​the PCB circuit board, and is configured to wake up the PCB circuit board circuit as the turntable rotates a second specified angle or a multiple of the second specified angle.

[0022] Another object of the present invention is to provide an input method of the rotary disk type password input structure as described above, characterized in that it comprises the following steps:

[0023] The turntable is rotated along the first direction to the first password mark, and the multiple contact angles on the metal spring are coupled and connected with the corresponding contact points in the password contact area;

[0025] The turntable is rotated along the first direction to the third password mark, and the multiple contact angles on the metal spring are coupled and connected with the corresponding contact points in the password contact area, and the PCB circuit board enters the working state and recognizes the second password;

[0026] Similarly, the above steps are repeated to input multiple passwords. When the turntable rotates to the last password mark, the turntable is rotated in the opposite direction to a third specified angle and stops, so that the last password is recognized.

[0027] In one example of the present invention, before the above steps, the PCB circuit board circuit is also awakened, which includes: rotating the turntable along the first direction by a second specified angle or a multiple of the second specified angle and then stopping.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0060] According to a first aspect of the present invention, a rotary disk type password input structure 100 is as follows: Figure 1 and Figure 2 As shown, including:

[0061] The turntable 110 is provided with password marks 113 at equal intervals along its circumferential direction and on its first end surface 111, wherein the interval angle between two adjacent password marks 113 is a first specified angle 115; for example, the password marks 113 include 10, then the first specified angle 115 is 36 degrees; for another example, the password marks 113 are numbers and / or letters.

[0062] The metal spring piece 120 is fixedly connected to the second end surface 112 of the turntable 110 away from the first end surface 111, and the metal spring piece 120 has a plurality of contact angles 122; for example, a mounting groove 116 is formed on the second end surface 112 of the turntable 110, and the metal spring piece 120 is fixedly connected in the mounting groove 116, and for another example, a fastener or a pin shaft can be arranged inside the mounting groove 116 to fix it.

[0063] The PCB circuit board 130 is relatively pivotally connected to one side of the metal spring 120 where the plurality of contact angles 122 are arranged, and the PCB circuit board 130 is provided with a plurality of contact points 134 distributed in the circumferential direction; wherein the plurality of contact points 134 are respectively arranged in the password contact area 132 and the wake-up contact area 133;

[0064] When the turntable 110 rotates the first specified angle 115 or a multiple of the first specified angle 115, the metal spring 120 contacts and conducts with the multiple contact points 134 of the password contact area 132, so that the PCB circuit board 130 is turned on and off to realize the code recognition of the password mark 113 on the turntable 110.

[0065] The working process of the input structure 100 is as follows: first, the circuit of the PCB circuit board 130 is awakened; then, the turntable 110 is rotated along a first direction to the first password mark 113, and the multiple contact angles 122 on the metal spring 120 are coupled and connected with the corresponding contact points 134 in the password contact area 132; then, the turntable 110 is rotated along a second direction opposite to the first direction to the second password mark 113, and the multiple contact angles 122 on the metal spring 120 are coupled and connected with the corresponding contact points 134 in the password contact area 132, and the PCB circuit board is connected. 130 enters the working state and recognizes the first password; the turntable 110 is rotated along the first direction again to the third password mark 113, and the multiple contact angles 122 on the metal spring 120 are coupled and conducted with the corresponding contact points 134 in the password contact area 132, and at the same time, the PCB circuit board 130 enters the working state and recognizes the second password; and so on, the above steps are repeated to realize the input of multiple passwords. Finally, when the turntable 110 rotates to the last password mark 113, the turntable 110 is rotated in the opposite direction by the third specified angle and stops, so that the last password is recognized.

[0066] The input structure 100 has a simple structure. By printing contact points 134 on the PCB, the password dial 110 and the metal spring 120 are snapped together, and the password can be input by rotating the password to the indicating point password contact area 132. The structure is simple and firm, not easily destroyed by violence, and has an anti-peeping function (keyboard passwords are very easy to be peeped during the input process). It is small in size and does not require the password to be scrambled after input like a multi-digit mechanical password. It can completely replace the mechanical password and has all the functions of the electronic password.

[0067] In one example of the present invention, Figure 3 and Figure 4 As shown, the metal dome 120 includes:

[0068] The main body 121 is provided with a connecting hole 1211, which is adapted to the rotating shaft 114 provided on the rotating disk 110;

[0069] The contact angle 122 is formed on one side of the main body 121 close to the PCB circuit board 130, and under the action of elastic deformation, the contact angle 122 has an elastic force that always resists the PCB circuit board 130, and is configured to contact and conduct with the contact point 134 of the password contact area 132 or the wake-up contact area 133 after synchronously rotating with the turntable 110 at a first specified angle 115 or a multiple of the first specified angle 115, a second specified angle or a multiple of the second specified angle, so as to realize the code recognition of the password mark 113 on the turntable 110 or the circuit wake-up of the PCB circuit board 130;

[0070] That is to say, the contact angle 122 contacts the PCB circuit board 130 so that the contact angle 122 is elastically deformed, and the contact angle 122 itself has a tendency to return to its initial position under the action of the elastic force. When the metal spring 120 rotates to a certain password contact area 132, the contact angle 122 thereon will be connected one-to-one with multiple contact points 134 of the password contact area 132, so that the circuit of the PCB circuit board 130 is awakened or the code of the password mark 113 on the turntable 110 is recognized.

[0071] In one example of the present invention, the contact angle 122 is formed by a bending process at one end away from the main body 121, wherein the bent portion of the contact angle 122 forms a protruding point 122A, and the protruding point 122A abuts against a contact point 134 of the PCB circuit board 130;

[0072] Specifically, each contact angle 122 can be made by the following process: first, the metal spring 120 is cut to form the contact angle 122 (for example, the cutting direction is open, and one end is retained to be connected to the main body 121 of the metal spring 120), and then the part connecting the contact angle 122 and the main body 121 is elastically bent so that the whole is biased toward one side of the PCB circuit board 130, and then a protrusion 122A is formed by a bending process at the end of the contact angle 122 away from the main body 121; through the above process, the metal spring 120 can be formed into an integral structure, and the overall structure is more reliable and easy to process.

[0073] In one example of the present invention, the contact angle 122 includes: a plurality of coding antennae 1221,

[0074] The connection holes 1211 are arranged at intervals on the main body 121 in the circumferential direction thereof, and the plurality of coding feelers 1221 are contact-coupled with the contact points 134 in the password contact area 132 on the PCB circuit board 130, and are configured to adjust the positions of the plurality of coding feelers 1221 by rotating the metal spring 120 so that different contact points 134 in the password contact area 132 of the PCB circuit board 130 are switched on and off to realize the code recognition of the password mark 113 on the turntable 110;

[0075] That is to say, the multiple coding antennae 1221 formed on the metal spring 120 and a part of the contact points 134 in the password contact area 132 on the PCB circuit board 130 are in a one-to-one correspondence. In this way, when the metal spring 120 rotates with the turntable 110 by the first specified angle 115, the multiple coding antennae 1221 on the metal spring 120 will be coupled and connected with another part of the contact points 134 in the password contact area 132, thereby enabling the on-off control of different contact points 134 in the password contact area 132 of the PCB circuit board 130 to realize the code recognition of the password mark 113 on the turntable 110.

[0076] For example, the three coding feelers 1221 on the metal dome 120 can be coupled and conducted with three of the multiple contact points 134 in the password contact area 132 on the PCB circuit board 130 before the turntable 110 rotates by the first specified angle 115. The three coding feelers 1221 on the metal dome 120 can also be coupled and conducted with the other three of the multiple contact points 134 in the password contact area 132 on the PCB circuit board 130 after the turntable 110 rotates by the first specified angle 115, thereby realizing the on-off control of different contact points 134 in the password contact area 132 of the PCB circuit board 130, thereby realizing the coding identification of the password mark 113 on the turntable 110; it can be understood that the three contact points 134 in the password contact area 132 corresponding to the metal dome 120 before and after the rotation may be partially repeated.

[0077] In an example of the present invention, the coding antenna 1221 is located on a circle with the center of the connecting hole 1211 as the center and the distance from any one of the coding antennas 1221 to the center as the radius, wherein the distances from the multiple coding antennas 1221 to the center include at least two different radius distances;

[0078] In other words, the plurality of coding tentacles 1221 are distributed on circles with the center of the connecting hole 1211 as the center and different sizes as the radius. By arranging the plurality of coding tentacles 1221 on different circles, it is possible to avoid distributing too many coding tentacles 1221 on a circle of the same diameter, which would cause the password contact area 132 to be too densely distributed and affect the arrangement of the password contact area 132.

[0079] For example, the coding antennae 1221 include three antennae, two of which are distributed on an outer circle with a larger diameter, and one is distributed on an inner circle with a smaller diameter.

[0080] In an example of the present invention, the coding antenna 1221 at each position on the main body 121 includes two, and the two coding antennas 1221 are arranged in parallel;

[0081] Providing two coding antennae 1221 at each position can improve the accuracy and reliability of the contact between the coding antennae 1221 and the contact point 134 , and avoid the situation where one coding antennae 1221 has poor contact.

[0082] In one example of the present invention, the contact angle 122 further includes: a wake-up feeler 1222,

[0083] It is suitable for stopping at the contact point 134 of the wake-up contact area 133 of the PCB circuit board 130, and is configured to wake up the circuit of the PCB circuit board 130 as the turntable 110 rotates a second specified angle or a multiple of the second specified angle; for example, the second specified angle may be 360 ​​degrees, that is, the turntable 110 rotates one circle;

[0084] For example, the wake-up antenna 1222 is set at the shaft 114 near the turntable 110. In actual use, each time the wake-up antenna 1222 rotates a circle and stops on the corresponding contact point 134 on the PCB again, the circuit of the PCB circuit board 130 can be awakened to facilitate the next operation; by setting the wake-up antenna 1222, the PCB circuit board 130 can be switched between the sleep and wake-up states, which saves energy while improving the safety of the input structure 100.

[0085] It is understandable that the opening method of the awakening antenna 1222 is the same as that of the encoding antenna 1221, which will not be repeated here.

[0086] In an example of the present invention, a mounting hole 131 adapted to the rotating shaft 114 is provided on the PCB circuit board 130, and the contact points 134 are respectively distributed in the password contact area 132 and the wake-up contact area 133 distributed in the radial direction, wherein the plurality of contact points 134 are coupled and conducted to each other;

[0087] The installation hole 131 can facilitate the connection between the PCB circuit board 130 and the rotating shaft 114 of the rotating disk 110;

[0088] The wake-up contact area 133 is disposed near the mounting hole 131, and the plurality of contact points 134 in the wake-up contact area 133 are disposed at equal arc intervals; for example, the contact points 134 are distributed at 36 degrees or multiples of 36 degrees;

[0089] The password contact area is distributed around the wake-up contact area 133, and its distribution is arranged in a designed manner, for example, Figure 5 and Figure 6 As shown;

[0090] The contact points 134 are distributed on the PCB circuit board 130. When the metal dome 120 rotates by the first specified angle 115, the coding antenna 1221 on the metal dome 120 will contact the contact point 134 corresponding to the password contact area, thereby realizing the coding recognition of the corresponding password mark 113; when the metal dome 120 rotates by the second specified angle, the awakening antenna 1222 on the metal dome 120 will contact the contact point 134 corresponding to the awakening contact area 133, thereby realizing the awakening of the PCB circuit board 130.

[0091] According to a second aspect of the present invention, an input method of the rotary disk type password input structure 100 as described above is as follows: Figure 7 As shown, the following steps are included:

[0092] Wake up the PCB circuit board 130 circuit;

[0093] The turntable 110 is rotated along the first direction to the first password mark 113, and the plurality of contact angles 122 on the metal spring 120 are coupled and conducted with the corresponding contact points 134 in the password contact area 132;

[0094] The turntable 110 is rotated in a second direction opposite to the first direction to the second password mark 113, and the multiple contact angles 122 on the metal spring 120 are coupled and connected with the corresponding contact points 134 in the password contact area 132, and the PCB circuit board 130 enters the working state and recognizes the first password;

[0095] The turntable 110 is rotated along the first direction to the third password mark 113, and the multiple contact angles 122 on the metal spring 120 are coupled and connected with the corresponding contact points 134 in the password contact area 132, and the PCB circuit board 130 enters the working state and recognizes the second password;

[0096] By analogy, the above steps are repeated to input a multi-digit password. When the turntable 110 rotates to the last password mark 113, the turntable 110 is rotated in the opposite direction to a third specified angle and stops, and the multiple contact angles 122 on the metal spring 120 are coupled and connected with the corresponding contact points 134 in the password contact area 132, and the PCB circuit board 130 enters the working state and the last password is recognized. For example, the third specified angle is 36 degrees or greater than 36 degrees (a multiple of 36 degrees).

[0097] The input method is simple. By printing the contact point 134 on the PCB, the password dial 110 and the metal spring 120 are snapped together, and the password is rotated to the indicating point password contact area 132 to input the password. The input method has an anti-peeping function (keyboard passwords are very easy to be peeped during the input process), is compact in size, and does not require the password to be scrambled after input like a multi-digit mechanical password. It can completely replace the mechanical password and at the same time has all the functions of the electronic password.

[0098] In one example of the present invention, before the above steps, the step also includes waking up the PCB circuit board 130 circuit, which includes: rotating the turntable 110 in the first direction to a second specified angle or a multiple of the second specified angle and then stopping; for example, the second specified angle is 360 degrees, that is, the turntable 110 rotates one circle to wake up the PCB circuit board 130.

[0099] Specific examples

[0100] like Figure 5 and Figure 6 As shown, a plurality of contact points 134 are distributed on the password contact area 132 on the PCB circuit board 130 according to the coding rules, and the plurality of contact points 134 are divided into 4 groups, and different contact points 134 are connected through a 6-point contact metal spring 120. Whenever the turntable 110 rotates 36 degrees, the metal spring 120 is connected to different contact points 134, thereby generating on-off control of the circuit, and realizing code recognition of a total of 10 digits from 0 to 9.

[0101] Similarly, the wake-up contact area 133 on the PCB circuit board 130 is also provided with a plurality of contact points 134 that are evenly distributed in a circular pattern (the number of contact points 134 is determined by a multiple of 36, a maximum of 10 can be set, and a minimum of 1 can be set. When set to one, the middle of the circular wake-up contact area 133 is in a disconnected state). The contact points 134 are connected to each other outside the circular area or on the back of the PCB circuit board 130, and contact the above-mentioned metal spring 120 through one of the contacts. When rotated to a certain angle, the on and off states can be switched to perform a circuit wake-up function.

[0102] For example, the number of digits of the password is four, and the specific method of implementing the password input is: first rotate the turntable 110 in a full circle forward / reverse and then stop at the first password mark 113, when dialing 36 / 72 degrees (it can also be other multiples of 36 degrees as needed), the circuit enters the working state and recognizes the number, then rotates the turntable in reverse / forward to the second password mark 113, then rotates the turntable in forward / reverse to the third password mark 113, and so on to achieve the input of multiple passwords, when the last password is input, it needs to be reversely rotated more than 36 degrees and stop to be correctly recognized. The rule of rotating the password input is the method of forward / reverse forward / reverse (positive, negative, negative, negative) in sequence, but it is not limited to this input method, and the method of reverse forward reverse forward (negative, negative, negative, negative) can also be used to input.

[0103] Of course, the present invention is not limited to this. This method of inputting passwords also has another ring structure. Two groups of 10 contact points are evenly distributed on the side of a cylinder, and each contact point of one group corresponds to a number.
