[0002] In the field of safety technology, electrical coding lock as an important electronic safety device is widely used in various occasions requiring access control or device enablement. Traditional electrical coding lock usually relies on the operator to observe the indicator light state on the lock body, or in some cases, needs to use additional mechanical key for auxiliary judgment to determine the on or off state of the internal working circuit of the lock (i.e. whether the current is allowed to pass in the circuit).
[0003] Specifically, when indicating the state, such traditional electrical coding lock often uses simple light emitting diode (LED) as visual feedback element. The operator needs to infer the connection state of the internal circuit of the lock according to the preset logic rules, such as the on-off, color change or flashing frequency of the indicator light. However, using LED or indicator light to display the circuit state is easy to be disturbed by environmental light; the operator needs to remember and understand the meaning represented by different indicator light states, which increases the complexity of operation and the possibility of error. Especially in the case of insufficient light or indicator light failure, the operator may have difficulty in accurately judging the circuit state, resulting in operation failure or inability to use normally.

[0024] To further illustrate each embodiment, the utility model provides with drawings. These drawings are part of the utility model disclosure, mainly used to illustrate the embodiment, and can cooperate with the relevant description of the specification to explain the operating principle of the embodiment. With reference to these contents, those skilled in the art should understand other possible embodiments and the advantages of the utility model. The components in the drawing are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0025] The utility model is further illustrated in connection with the drawings and specific embodiments.
[0026] As Figures 1-5 shown, the embodiment provides an electrical coded lock 1. The electrical coded lock 1 includes a housing 10, a printed circuit board assembly (PCBA) 20, a base assembly 30 and a receiver 40. The base assembly 30 includes a base 31, a slider 32, a micro switch 33 and a motor 34. The slider 32 is slidably mounted on the base 31. The motor 34 is connected with an eccentric cam 341 at one end, and the eccentric cam 341 acts on the slider 32, so that the motor 34 can drive the slider 32 to displace on the base 31. The slider 32 abuts against a button 331 of the micro switch 33. When the motor 34 drives the slider 32 to move from a first position to a second position, the slider 32 acts on the button 331 of the micro switch 33 and changes the state of the micro switch 33, i.e., the micro switch 33 changes from a first state to a second state. Specifically, in the embodiment, a mechanical change occurs inside the micro switch 33, and the COM pin and the NC pin of the micro switch 33 change from a conductive state to a non-conductive state, while the COM pin and the NO pin change from a non-conductive state to a conductive state.
[0027] The slider 32 is provided with an indication tongue block 326, the housing 10 is provided with an indication window 11, and one side of the indication window 11 is provided with an indication mark 13. In the embodiment, the indication mark 13 is two indication marks of “split” and “close”, which respectively represent the disconnection or conduction state of the working circuit. The indication tongue block 326 protrudes into the indication window 11. In the embodiment, when the slider 32 is in the first position, the indication tongue block 326 corresponds to the “split” mark; when the slider 32 is in the second position, the indication tongue block 326 corresponds to the “close” mark. When the working circuit needs to be conducted, the printed circuit board assembly (PCBA) 20 sends a command to the motor 34, and the motor 34 rotates and drives the slider 32 to move at the same time. When the slider 32 moves and presses the button 331 of the micro switch 33, the two pins connected with wires of the micro switch 33 change from a non-conductive state to a conductive state, the working circuit is conducted, the indication tongue block 326 moves from the “split” mark to the “close” mark, i.e., the indication window 11 displays the “close” state, and the electrical coded lock 1 is turned on.
[0028] Conversely, when the circuit needs to be disconnected after the work is completed, the printed circuit board assembly 20 sends a command to the motor 34 to rotate in the opposite direction, while driving the slider 32 to move in the opposite direction. When the slider 32 moves, the button 331 of the micro switch 33 pressed off the slider 32. The micro switch 33 automatically returns to the original state. At this time, the two wire-connected pins of the micro switch 33 change from the conduction state to the non-conduction state. At the same time, the indicating tongue block 326 moves from the "on" mark to the "off" mark, that is, the indicating window 11 displays the "off" state, and the electric coded lock 1 is not conductive. The electric coded lock 1 of the embodiment can visually determine whether the internal structure of the electric coded lock 1 is conductive or disconnected through the visual indicating window 11 on the shell 10, so as to determine whether the working circuit is powered or not. The line state display is more intuitive, and the judgment is more simple and convenient, and misreading is less likely to occur.
[0029] In the embodiment, the shell 10 includes a panel 12 and a side plate 14 surrounding the panel 12. The panel 12 and the side plate 14 surround to form a cavity structure with an opening at the bottom. The shell 10 can be installed and matched with the base 31, so that the base 31 closes the opening at the bottom of the shell 10, and the slider 32, the micro switch 33 and the motor 34 are installed in the cavity between the base 31 and the shell 10, thereby forming good protection for the internal elements.
[0030] The panel 12 is formed with a mounting groove 15 adapted to mount the receiver 40. The receiver 40 is electrically connected with the printed circuit board assembly 20. The receiver 40 can receive wireless signals, for example, the wireless signals of a remote controller or a remote key, and can transmit the wireless signal data to the printed circuit board assembly 20. The printed circuit board assembly 20 determines whether to send a rotating command to the motor 34 according to the received signal data, and controls the rotating direction and / or rotating angle of the motor. The electric coded lock 1 of the embodiment can be controlled by a remote controller or a remote key, and the convenience and safety are greatly improved.
[0031] The slider 32 includes a slider body 321 extending in a longitudinal direction. A pushing long groove 323 is recessed on the slider body 321. The pushing long groove 323 can be matched with the eccentric cam 341 of the motor 34, and the rotating movement of the motor 34 is converted into the longitudinal displacement movement of the slider 32 through the matching structure. The matching structure is simple and has high reliability.
[0032] The slider 32 further includes a pushing block 322 extending in a transverse direction from the slider body 321. The pushing block 322 abuts against the button 331 of the micro switch 33, so that the longitudinal displacement movement of the slider 32 can push the button 331, and thus change the state of the micro switch 33. The structure is simple and reliable.
[0033] The slider 32 further comprises a connecting portion 324 extending upwardly from the slider body 321, and a top end of the connecting portion 324 is provided with a flat piece 325, and an indicating tongue 326 is arranged on an upper surface of the flat piece 325. The flat piece 325 is matched to a lower surface of the panel 12, an area of the flat piece 325 is greater than an area of the indicating window 11, and the flat piece 325 can always cover the indicating window 11 from below during sliding of the slider 32, so as to prevent foreign matters from falling into an inside of the electrical coded lock 1 to cause a fault, improve reliability of the electrical coded lock 1, and also enable the flat piece 325 to play a certain guiding role for displacement movement of the slider 32 in cooperation with the lower surface of the panel 12.
[0034] The base 31 is provided with a first guide protrusion 311, a second guide protrusion 312 and a third guide protrusion 313, and the slider body 321 of the slider 32 is provided with a first guide surface 327, a second guide surface 328 and a third guide surface 329 matched respectively, the first guide surface 327 and the second guide surface 328 are located on opposite sides of the slider body 321, and the third guide surface 329 is arranged on a back side of the pushing long groove 323, so that the slider 32 can be movably mounted on the base 31, and the displacement movement of the slider 32 can be guided through cooperation of the three positions, and the displacement movement of the slider 32 is more accurate.
[0035] In the embodiment, the eccentric cams 341 of the pushing long grooves 323 are matched to each other, so that the slider 32 is limited in the longitudinal direction, and thus longitudinal limitation is not needed. However, the slider body 321 of the slider 32 can further be provided with a first positioning shoulder 3211 and a second positioning shoulder 3212, the first positioning shoulder 3211 and the second positioning shoulder 3212 correspond to the first positioning column 314 and the third guide protrusion 313 on the base 31 respectively, so as to assist installation of the slider 32 on the base 31 and make the installation more convenient.
