Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, and particularly relates to a password lock structure for a rail transit sightseeing area. Background Art

[0002] With the leap of rail transit technology, the CR450 high-speed train sets high standards for the cab door lock, requiring it to balance safety, reliability, and convenience and incorporate intelligence. Although existing intelligent password locks are widely used in the civilian field, they are difficult to meet the unique requirements of the train cab, especially in terms of safety, durability, and battery usage. Therefore, the industry is seeking innovation. For example, the door lock solution designed in Chinese Patent CN214062651U realizes secondary locking through the cooperation of multiple locks, improving the opening and closing convenience. However, this solution still needs to be optimized in terms of the intuitiveness of the locked state, instant feedback, and material durability to fully adapt to the special challenges of the complex operating environment of rail trains and ensure the excellent performance of the cab door lock. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a password lock structure for a rail transit sightseeing area.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] A password lock structure for a rail transit sightseeing area includes a lock body fixed on the door panel of a rail train. The lock body is flat and includes a square lock tongue and an inclined lock tongue; a square opening is provided on the lock body; the square opening is respectively aligned and connected with an inner handle composite plate and a password outer composite plate, and a lock core is inserted and fixed; the inner handle composite plate includes an inner composite plate, an inner handle, a handle stop iron, a return torsion spring, and a square steel. The inner handle passes through the inner composite plate and is sleeved with the return torsion spring, and then passes through the handle stop iron; the inner handle is reset through the handle stop iron and the return torsion spring; the square steel passes through the square opening of the lock body; the password outer composite plate includes an outer composite plate, an outer handle, and an idle rotor. The outer handle passes through the outer composite plate and is rotatably connected with the idle rotor. The idle rotor is aligned with the square steel and is used to transmit the rotation action of the outer handle.

[0006] This technical solution uses stainless steel material, has high-strength safety, and is an electronic password lock for rail trains powered by an electrified hinge to solve the deficiencies of the prior art and meet the special requirements of the driver's cab of rail trains. Specifically, the square opening on the lock body is used to align with the key components in the inner cladding and the password outer cladding to ensure that the lock core can be correctly inserted and fixed, thereby realizing the locking function; the inner handle cladding is located outside the door, and the reset function of the inner handle is realized through a reset torsion spring and a handle stop iron; the square steel is used as a connecting piece, passes through the opening of the lock body and aligns with the idle rotor in the password outer cladding to transmit the rotation action; the password outer cladding is located inside the door and includes electronic components such as an outer handle, an idle rotor, a display screen, a touch panel, and a main control board. The rotation of the outer handle is transmitted through the idle rotor and cooperates with the square steel to realize the unlocking action.

[0007] According to an embodiment of the present invention, the inner handle cladding is located outside the sightseeing area door. When the outer handle is pressed down, the outer handle is in an idle state to prevent people from accidentally entering inside the sightseeing area door; when the inner handle is pressed down, the diagonal locking tongue and the square locking tongue retract simultaneously, allowing the driver to directly open the door.

[0008] When the outer handle is lifted, the diagonal locking tongue and the square locking tongue extend simultaneously to realize locking; when the inner handle is lifted, the diagonal locking tongue and the square locking tongue extend simultaneously to realize locking.

[0009] In this technical solution, when the outer handle is pressed down, it is in an idle state, that is, it does not drive the locking tongue to move, which is to prevent the door from being opened due to incorrect operation inside the door in places such as the sightseeing area; when the outer handle is lifted, the diagonal locking tongue and the square locking tongue are simultaneously driven to extend through the internal mechanical transmission mechanism to realize locking. When the inner handle is pressed down, the diagonal locking tongue and the square locking tongue are also simultaneously driven to retract through the internal mechanical transmission mechanism to allow the door to be opened; when the inner handle is lifted, it has the same function as when the outer handle is lifted, and also simultaneously drives the diagonal locking tongue and the square locking tongue to extend to realize locking.

[0010] According to an embodiment of the present invention, two protruding claws are provided on the handle stop iron of the inner handle cladding. These claws rotate a certain angle to contact the cylindrical protrusion on the inner cladding to achieve the function of limiting the handle; after the reset torsion spring is stressed, the two fixed claws contact the cylinder of the inner cladding.

[0011] In this technical solution, washers and adjusting washers are used to adjust the gap between the inner handle and the inner cladding plate to ensure the stability and smoothness of the handle during operation; the snap ring is used to fix the entire inner handle assembly to prevent it from loosening or falling off during use; the raised part in the middle of the handle stop iron is sleeved into the groove of the inner handle to achieve the fixation of the inner handle. The handle stop iron not only fixes the handle, but also ensures the stability of the handle during operation and the reliability of force transmission through the cooperation between its raised part and the groove of the inner handle. The return torsion spring allows the handle to automatically reset after rotating in both directions, improving the convenience and comfort of use. This also reduces the force that the user needs to apply when operating the handle because the return torsion spring will help the handle return to its initial position. When the user operates the inner handle, the rotational force of the handle is transmitted to the internal mechanism of the lock body through the handle stop iron, thereby driving the protrusion or retraction of the lock tongue.

[0012] According to an embodiment of the present invention, the inner cladding plate is made of stainless steel and is provided with reinforcing ribs in the inner cavity.

[0013] In this technical solution, the claw is the raised part on the handle stop iron and is used to contact and interact with the cylindrical protrusion on the inner cladding plate; when the claw rotates to a certain angle, once the claw contacts the cylindrical protrusion, the further rotation of the handle will be restricted, which is used to limit the movement range of the handle stop iron and achieve an effective limiting effect.

[0014] According to an embodiment of the present invention, the password outer cladding plate is located inside the sightseeing area door. The password outer cladding plate further includes a free part, and the free part includes a handle rotor and a spring pin. Among them: after the spring pin is stressed, it expands and contracts along the direction of the hole on the handle rotor; the idle rotor rotates inside the handle rotor. When the spring pin in the free part assembly presses up, the spring pin just snaps into the groove of the idle rotor, and at this time, the idle rotor and the handle rotor become one body.

[0015] This technical solution realizes an effect of being able to quickly connect and separate when needed through the cooperation of the free part and the idle rotor. The idle rotor is provided with grooves for cooperation with the spring pin; when the user needs to unlock the password of the password outer cladding plate, the user will press or operate the spring pin in the free part; the spring pin extends after being stressed and just snaps into the groove of the idle rotor; once the spring pin snaps into the groove, a fixed connection is formed between the idle rotor and the handle rotor, and at this time they will rotate as a whole; while when not needed, their relative independence is maintained.

[0016] According to an embodiment of the present invention, the password outer cladding plate further includes a display screen, a touch panel and a main control board. The main control board is respectively connected to the display screen and the touch panel to realize the change of the relative unlocking action of the idle rotor.

[0017] In this technical solution, the display screen and the touchpad are used for user input and information display; the main control board receives input signals from the touchpad or the display screen, and determines whether to execute an unlocking action according to a preset logic; when the user needs to unlock, the correct password or a specific unlocking operation is input through the touchpad or the display screen; after receiving the input signal, the main control board determines its validity and sends an unlocking instruction to the motor clutch; the motor clutch cooperates with the idle rotor to act, and cooperates with the lock body through the square steel to achieve the unlocking action; the reset mechanism in the inner handle cover plate ensures automatic reset after unlocking to prepare for the next locking.

[0018] According to an embodiment of the present invention, the password outer cover plate further includes a motor clutch and a driving bracket. The driving bracket of the motor clutch is set to be arc-shaped. When the power is off or no password is inputted / no card is swiped, the driving bracket of the motor clutch is in a contracted state; when the password outer cover plate assembly is powered on, by swiping the card / inputting the correct password, the motor clutch acts, the lifted driving bracket contacts the free part, and the elastic pin is lifted. At this time, the idle rotor and the free part assembly and the door handle become an integral state. At this time, pressing down the outer door handle unlocks and opens the door.

[0019] In this technical solution, the motor clutch is responsible for generating an action when receiving a specific signal; the driving bracket is set to be arc-shaped and can perform telescopic movement under the drive of the motor clutch. When the power is off or no password is inputted / no card is swiped, the driving bracket of the motor clutch is in a contracted state and does not contact other components; when the password outer cover plate assembly is powered on and the user verifies by swiping the card or inputting the correct password, the motor clutch receives the signal and generates an action; the action of the motor clutch causes the driving bracket to extend from the contracted state and lift the elastic pin in the free part; after the elastic pin is lifted, it just snaps into the groove of the idle rotor. At this time, the idle rotor, the free part and the door handle become a whole. In this integral state, the user can press down the outer door handle to unlock and open the door; through the setting of the motor clutch and the driving bracket, the control of the free part and the idle rotor is realized under specific conditions (powered on and verified); the interaction between the free part and the idle rotor enables the door handle to become a whole with them after verification, thereby allowing the user to perform the unlocking operation, improving the security and convenience of the password outer cover plate assembly. Only after verification can the unlocking operation be performed. It is applied to the access control system that requires high security, controls the unlocking of the door through electronic verification, and improves the security; after verification, the door can be conveniently unlocked by pressing down the handle, maintaining the convenience of use.

[0020] According to an embodiment of the present utility model, the motor clutch is connected to the driving plate. When the driving plate controls the motor clutch to jack up, pressing down the outer handle opens the door; when the driving plate controls the motor clutch to reset to the contracted state, pressing down the outer handle cannot open the door, and at this time, the outer handle is in an idle rotation state.

[0021] In this technical solution, when the driving plate issues an instruction, the motor clutch will jack up or reset accordingly. When the driving plate controls the motor clutch to jack up, the driving bracket of the motor clutch will extend, jack up the elastic pin in the free part, and make it snap into the groove of the idle rotor, so that the outer handle is connected to the unlocking mechanism of the door lock. Pressing down the outer handle will trigger the unlocking mechanism, thus opening the door; on the contrary, when the driving plate controls the motor clutch to reset to the contracted state, the driving bracket of the motor clutch will retract, disconnecting the connection between the outer handle and the unlocking mechanism. At this time, even if the outer handle is pressed down, the unlocking mechanism cannot be triggered because the outer handle is in an idle rotation state, that is, it is no longer connected to any unlocking components of the door lock.

[0022] Compared with the prior art, the present utility model has the following beneficial effects:

[0023] The present utility model is specially designed for the driver's cab of rail trains, integrating high safety, battery-free power supply, convenient operation and long service life; adopting stainless steel material and multiple mechanical lock body structures to ensure firm and reliable performance in extreme environments; abandoning batteries and adopting hinge power supply with a 5V safety voltage to meet the strict safety standards of rail transit; in terms of operation, one-key up and down opening and closing combined with multi-mode unlocking is efficient and convenient; in addition, it has excellent durability and low maintenance cost, suitable for high-frequency use; in summary, the present utility model not only meets the high standards of rail transit equipment, but also solves industry problems with an innovative power supply solution, with broad prospects and significant value.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] As Figures 1 to 2 shown, this embodiment provides a password lock structure for a rail transit sightseeing area, including a lock body 1 fixed on the door panel of a rail train. The lock body 1 is flat and includes a square lock tongue 13 and an oblique lock tongue 12. A square opening 11 is provided on the lock body 1. The square opening 11 is respectively aligned and connected with the inner handle back plate 2 and the password outer back plate 3, and penetrates into the lock core for fixation. The inner handle back plate 2 includes an inner back plate 21, an inner handle 22, a handle stop iron 23, a return torsion spring 24 and a square steel 25. The inner handle 22 passes through the inner back plate 21 and is sleeved with the return torsion spring 24, and then passes through the handle stop iron 23. The inner handle is reset by the handle stop iron 23 and the return torsion spring 24. The square steel 25 passes through the square opening 11 of the lock body 1. The password outer back plate 3 includes an outer back plate 31, an outer handle 32 and an idle rotor 33. The outer handle 32 passes through the outer back plate 31 and is rotatably connected with the idle rotor 33. The idle rotor 33 is aligned with the square steel 25 for transmitting the rotation action of the outer handle 32.

[0035] As Figures 1 to 7As shown in the figure, this technical solution uses stainless steel material, has high-strength safety, and is an electronic password lock for rail trains powered by an electrified hinge to solve the deficiencies of the prior art and meet the special requirements of the driver's cab of rail trains. Specifically, the square opening 11 on the lock body 1 is used to align with the key components in the inner cladding plate 21 and the password outer cladding plate 3 to ensure that the lock core can be correctly inserted and fixed, thereby realizing the locking function; the inner handle cladding plate 2 is located outside the door, and the inner handle 22 is reset through the reset torsion spring 24 and the handle stop iron 23; the square steel 25 is used as a connecting piece, passes through the opening of the lock body 1 and aligns with the idle rotor 33 in the password outer cladding plate 3 to transmit the rotation action; the password outer cladding plate 3 is located inside the door and includes electronic components such as an outer handle 32, an idle rotor 33, a display screen 34, a touch panel 35, and a main control board 36. The rotation of the outer handle 32 is transmitted through the idle rotor 33 and cooperates with the square steel 25 to realize the unlocking action.

[0036] As Figure 4 shown, the inner handle cladding plate 2 is located outside the sightseeing area door. When the outer handle 32 is pressed down, the outer handle 32 is in an idle state to prevent people from accidentally entering inside the sightseeing area door; when the inner handle 22 is pressed down, the inclined locking tongue 12 and the square locking tongue 13 are retracted simultaneously, allowing the driver to directly open the door;

[0037] When the outer handle 32 is lifted, the inclined locking tongue 12 and the square locking tongue 13 are extended simultaneously to realize locking; when the inner handle 22 is lifted, the inclined locking tongue 12 and the square locking tongue 13 are extended simultaneously to realize locking.

[0038] In this technical solution, when the outer handle 32 is pressed down, it is in an idle state, that is, it does not drive the locking tongue to move, which is to prevent the door from being opened due to misoperation inside the door in places such as the sightseeing area; when the outer handle 32 is lifted, the inclined locking tongue 12 and the square locking tongue 13 are driven to extend simultaneously through the internal mechanical transmission mechanism to realize locking. When the inner handle 22 is pressed down, the inclined locking tongue 12 and the square locking tongue 13 are also driven to retract simultaneously through the internal mechanical transmission mechanism to allow the door to be opened; when the inner handle 22 is lifted, it has the same function as when the outer handle 32 is lifted, and also drives the inclined locking tongue 12 and the square locking tongue 13 to extend simultaneously to realize locking.

[0039] As Figure 4 shown, there are two protruding claws on the handle stop iron 23 of the inner handle cladding plate 2. These claws rotate a certain angle to contact the protruding cylinder 28 on the inner cladding plate 21 to play the role of limiting the handle; after the reset torsion spring 24 is stressed, the two fixed claws contact the cylinder 28 of the inner cladding plate 21.

[0040] In this technical solution, the washer 26 and the adjusting washer 27 are used to adjust the gap between the inner handle 22 and the inner cladding plate 21 to ensure the stability and smoothness of the handle during operation; the snap ring is used to fix the entire inner handle 22 assembly to prevent it from loosening or falling off during use; the raised part in the middle of the handle stop 23 is sleeved into the groove of the inner handle 22 to fix the inner handle 22. The handle stop 23 not only fixes the handle but also ensures the stability of the handle during operation and the reliability of force transmission through the cooperation between its raised part and the groove of the inner handle 22. The return torsion spring 24 allows the handle to automatically return to its original position after being rotated bidirectionally, improving the convenience and comfort of use. This also reduces the force that the user needs to apply when operating the handle because the return torsion spring 24 will help the handle return to its initial position. When the user operates the inner handle 22, the rotational force of the handle is transmitted to the internal mechanism of the lock body 1 through the handle stop 23, thereby driving the protrusion or retraction of the lock tongue.

[0041] As Figure 4 shown, the inner cladding plate 21 is made of stainless steel and is provided with reinforcing ribs in its inner cavity.

[0042] In this technical solution, the claw is the raised part on the handle stop 23 and is used to contact and interact with the raised part of the cylinder 28 on the inner cladding plate 21; when the claw rotates to a certain angle, once the claw contacts the raised part of the cylinder 28, the further rotation of the handle will be restricted, which is used to limit the movement range of the handle stop 23 to achieve an effective limiting effect.

[0043] As Figure 4 shown, the password outer cladding plate 3 is located inside the sightseeing area door. The password outer cladding plate 3 further includes a free part 37. The free part 37 includes a handle rotor 371 and a spring pin 372. Among them: after the spring pin 372 is stressed, it expands and contracts along the direction of the hole on the handle rotor 371; the idle rotor 33 rotates inside the handle rotor 371. When the spring pin 372 in the free part 37 is pressed, the spring pin 372 just snaps into the groove of the idle rotor 33. At this time, the idle rotor 33 and the handle rotor 371 become an integral body.

[0044] This technical solution realizes an effect of being able to quickly connect and separate when needed through the cooperation between the free part 37 and the idle rotor 33. The idle rotor 33 is provided with a groove for cooperating with the spring pin 372; when the user needs to unlock the password of the password outer cladding plate 3, the user will press or operate the spring pin 372 in the free part 37; the spring pin 372 extends after being stressed and just snaps into the groove of the idle rotor 33; once the spring pin 372 snaps into the groove, a fixed connection is formed between the idle rotor 33 and the handle rotor 371, and at this time they will rotate as a whole; while when not needed, their relative independence is maintained.

[0045] As Figures 5 to 7As shown, the password outer cover plate 3 further includes a display screen 34, a touch panel 35, and a main control board 36. The main control board 36 is respectively connected to the display screen 34 and the touch panel 35 to realize the change of the relative unlocking action of the idle rotor 33.

[0046] In this technical solution, the display screen 34 and the touch panel 35 are used for users to input and display information; the main control board 36 receives the input signals from the touch panel 35 or the display screen 34, and judges whether to execute the unlocking action according to the preset logic; when the user needs to unlock, the correct password is input through the touch panel 35 or the display screen 34 or a specific unlocking operation is performed; after the main control board 36 receives the input signal, it judges its validity and sends an unlocking instruction to the motor clutch 38; the motor clutch 38 cooperates with the action of the idle rotor 33 and is matched with the lock body 1 through the square steel 25 to realize the unlocking action; the reset mechanism in the inner handle cover plate 2 ensures that it can automatically reset after unlocking to prepare for the next locking.

[0047] According to an embodiment of the present invention, the password outer cover plate 3 further includes a motor clutch 38 and a driving bracket 39. The driving bracket 39 of the motor clutch 38 is arranged in an arc shape. When the power is off or no password is input or no card is swiped, the driving bracket 39 of the motor clutch 38 is in a contracted state; when the password outer cover plate 3 is powered on, by swiping the card / inputting the correct password, the motor clutch 38 is actuated, the lifted driving bracket 39 contacts the free part 37, and the elastic pin 372 is lifted. At this time, the idle rotor 33, the free part 37 assembly, and the door handle become an integrated state. At this time, pressing down the outer door handle 32 unlocks the door and opens it.

[0048] As Figures 5 to 7As shown in the figure, the motor clutch 38 is used to be responsible for generating an action when receiving a specific signal; the driving bracket 39 is set to be arc-shaped and can perform telescopic movement under the drive of the motor clutch 38. When there is no power supply or no password is input or no card is swiped, the driving bracket 39 of the motor clutch 38 is in a contracted state and does not contact other components; when the password outer cover 3 assembly is powered on and the user verifies by swiping the card or inputting the correct password, the motor clutch 38 receives the signal and generates an action; the action of the motor clutch 38 causes the driving bracket 39 to extend from the contracted state and jack up the elastic pin 372 in the free part 37; after the elastic pin 372 is jacked up, it just snaps into the groove of the idle rotor 33. At this time, the idle rotor 33, the free part 37 and the door handle become an integral body. In this integral state, when the user presses down the outer door handle 32, the door can be unlocked and opened; through the setting of the motor clutch 38 and the driving bracket 39, the control of the free part 37 and the idle rotor 33 is realized under specific conditions (powered on and verified successfully); the interaction between the free part 37 and the idle rotor 33 enables the door handle to become an integral body with them after verification, so as to allow the user to perform the unlocking operation, improving the security and convenience of the password outer cover 3 assembly. The unlocking operation can only be performed after verification, which is applied to the access control system that requires high security. The unlocking of the door is controlled through the electronic verification method, improving the security; after verification, the door can be conveniently unlocked by pressing down the door handle, maintaining the convenience of use.

[0049] According to an embodiment of the present invention, the motor clutch 38 is connected to the active plate. When the active plate controls the motor clutch 38 to jack up, pressing down the outer door handle 32 can open the door; when the active plate controls the motor clutch 38 to reset to the contracted state, pressing down the outer door handle 32 cannot open the door, and at this time, the outer door handle 32 is in an idle rotation state.

[0050] In this technical solution, when the active plate issues an instruction, the motor clutch 38 will jack up or reset accordingly. When the active plate controls the motor clutch 38 to jack up, the driving bracket 39 of the motor clutch 38 will extend, jack up the elastic pin 372 in the free part 37, and make it snap into the groove of the idle rotor 33, connecting the outer door handle 32 to the unlocking mechanism of the door lock. Pressing down the outer door handle 32 will trigger the unlocking mechanism, thus opening the door; on the contrary, when the active plate controls the motor clutch 38 to reset to the contracted state, the driving bracket 39 of the motor clutch 38 will retract, disconnecting the connection between the outer door handle 32 and the unlocking mechanism. At this time, even if the outer door handle 32 is pressed down, the unlocking mechanism cannot be triggered because the outer door handle 32 is in an idle rotation state, that is, it is no longer connected to any unlocking components of the door lock.

[0051] The usage process of the above embodiment is as follows:

[0052] First, the password outer cover plate 3 is located inside the door and contains electronic components such as a display screen 34, a touch panel 35, a main control board 36, etc., which are used to receive the password or card-swipe information input by the user; after the user inputs the correct password or swipes the card through the touch panel 35 or the display screen 34, the main control board 36 verifies the validity of the information; after the verification is passed, the main control board 36 sends a signal to the motor clutch 38 to drive its operation; the arc-shaped drive bracket 39 of the motor clutch 38 extends after receiving the signal, jacks up the elastic pin 372 in the free part 37, and makes it snap into the groove of the idle rotor 33, realizing the connection between the idle rotor 33 and the handle rotor 371; at this time, the outer handle 32 is connected to the door lock unlocking mechanism; when the user presses down the outer handle 32, through the cooperation of the idle rotor 33 and the square steel 25, the diagonal locking tongue 12 and the square locking tongue 13 in the lock body 1 are simultaneously retracted, realizing unlocking and allowing the door to be opened; if the user lifts up the outer handle 32, the locking tongue will extend through the same mechanism to realize locking; the inner handle cover plate 2 is located outside the door, and its operation principle is similar to that of the outer handle 32, but no electronic verification is required; when the user presses down the inner handle 22, the locking tongue is retracted through the internal mechanical transmission mechanism, allowing the door to be opened; lifting up the inner handle 22 makes the locking tongue extend to realize locking; in addition, the handle stop iron 23 and the return torsion spring 24 on the inner handle cover plate 2 ensure that the handle can automatically reset after operation, improving the convenience of use; the entire lock body 1 is made of stainless steel, combined with a high-strength mechanical lock body 1 structure and multiple unlocking methods, ensuring stable and reliable performance even under high-speed train operation or harsh environments; in summary, the intelligent password lock of this embodiment realizes high safety, reliability, and convenient operation of the cab door of the rail train through the combination of electronic verification and mechanical transmission.
