Description

Technical Field

[0001] The present invention relates to the technical field of safes, and in particular to a door lock mechanism of a safe. Background Art

[0002] Safes are used to store valuables such as property and documents and are widely used in banks, businesses, hotels, and homes. They typically have a main lock and an emergency lock. If the main lock malfunctions or the user forgets the main lock combination, the emergency lock can be used to unlock the safe.

[0003] For example, the applicant's Chinese utility model patent application number CN201721253529.X (publication number CN207363485U) discloses a "Lock-activation and operation structure for a safe deposit box transmission mechanism." This lock-activation and operation structure includes a door panel, a keyhole provided on the door panel, a controller panel mounted on the front of the door panel, a transmission mechanism and an emergency lock mounted on the back of the door panel, and a lock bracket secured to the back of the door panel at a position corresponding to the keyhole. The transmission mechanism includes a base, on which are mounted a motor, a bolt head, a connecting rod, and a mainboard PCB. The motor is mounted on the base via a motor slider, allowing it to slide laterally a certain distance. The bolt head is mounted on the base via a bolt head arm, allowing it to slide laterally a certain distance. One end of the bolt head arm is connected to the motor's eccentric cam, and one end of the connecting rod is connected to the motor slider, while the other end is connected to the emergency lock via a shift fork. This lock-activation and operation structure is easy to process and assemble, can be installed with different types of panels, and has strong practical performance.

[0004] For example, Chinese utility model patent application number CN201621129592.8 (publication number CN206233769U) discloses a "Safe Latching Structure with Emergency Function." This structure includes a main slide, a motor, an emergency slide, and a self-locking plate. The main slide is driven by the rotation of the motor output shaft or the forward and backward sliding movement of the motor. The emergency slide is restrained to the back of the door panel and can slide forward and backward along the door panel. The motor is mounted on the emergency slide. The self-locking plate is rotated on the back of the door panel via a pin. Under normal circumstances, the self-locking plate locks the emergency slide to prevent it from moving backward. An emergency cam, driven to rotate by an emergency lock, is located on the back of the door panel. A portion of the emergency cam mates with the self-locking plate, while another portion of the emergency cam is transmission-connected to the emergency slide. Rotation of the emergency cam deflects the self-locking plate, releasing the lock on the emergency slide and simultaneously driving the emergency slide backward. This structure is suitable for use in safe latching structures with emergency functions that are opened and closed by a motor.

[0005] However, the above patents all have the following problems: the emergency locks are all opened by an emergency key, so the emergency key needs to be stored in a safe place at ordinary times. The emergency key has the risk of being stolen by others and has low security; in addition, if the emergency key is lost, the emergency lock cannot be opened. At this time, it can only be opened by a special locksmith, which may damage the safe or delay the time to retrieve items from the safe. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a door lock mechanism for a safe which is highly safe and easy to use in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a door lock mechanism for a safe, including a master password input part, a main controller, a locking mechanism and an emergency slide, the locking mechanism is used to lock or unlock the door panel and the box body, the master password input part is connected to the main controller, the main controller is connected to the power part of the locking mechanism, and the power part of the locking mechanism is arranged on the emergency slide, characterized in that:

[0008] It also includes an emergency power supply, an emergency password input part, an emergency controller, an emergency motor and an emergency transmission structure. The emergency power supply is used to power the emergency password input part, the emergency controller and the emergency motor. The emergency password input part is connected to the emergency controller, the emergency controller is connected to the emergency motor, and the emergency motor drives the emergency slide to slide horizontally through the emergency transmission structure.

[0009] As an improvement, the main password input part and the emergency password input part are the same part, or they are different parts.

[0010] Preferably, the master password input part is a fingerprint collector, a password input keyboard, a door card, or Bluetooth;

[0011] Or / and, the emergency password input part is a password input keyboard or a fingerprint collector or a door card or Bluetooth.

[0012] The emergency transmission structure can be of various types. Preferably, the emergency slide has a second strip-shaped hole, and the emergency transmission structure includes an emergency turntable. The second eccentric pin of the emergency turntable extends into the second strip-shaped hole. The emergency turntable rotates, driving the second eccentric pin to move within the second strip-shaped hole and drive the emergency slide to slide laterally. The emergency transmission structure can also adopt a worm gear mechanism or a rack and pinion mechanism.

[0013] The power component of the locking mechanism can have various structures. Preferably, the power component of the locking mechanism includes a main motor disposed on the emergency slide. The locking mechanism also includes a main rotary disk, a bolt head arm, and a bolt head. The bolt head is connected to the bolt head arm. The bolt head arm has a first strip hole. The main rotary disk has a first eccentric pin. The first eccentric pin extends into the first strip hole. The main motor rotates to drive the first eccentric pin to move within the first strip hole and drive the bolt head to move laterally. The power component of the locking mechanism can also be an electromagnet.

[0014] In order to prevent the emergency turntable from rotating when the main motor is running, a balancing structure is also included to prevent the emergency turntable from rotating when the main motor is running.

[0015] There can be multiple types of balancing structures. Preferably, when the emergency motor is not started, the angle between the direction of the line connecting the center of the second eccentric pin of the emergency turntable and the rotation center of the emergency turntable and the sliding direction of the emergency slide is β, 0≤β≤10°, which constitutes the balancing structure.

[0016] Because the main motor vibrates during operation and has a reaction effect on the emergency slide, the emergency slide tends to slide relative to the door panel. The direction of the line connecting the rotation center of the emergency turntable and the center of the second eccentric pin is basically parallel to the sliding direction of the emergency slide. In this way, because the second eccentric pin can maintain its original position and will not drive the emergency turntable to rotate due to the force of the emergency slide, the emergency slide will not slide due to the rotation of the emergency turntable, thereby changing the position of the main motor and interfering with the operation of the bolt head arm.

[0017] In order to guide the sliding of the emergency slide and prevent the emergency turntable from rotating when the main motor is running, the door lock mechanism of the safe further includes a door panel, one of the emergency slide and the door panel has a second guide portion, and the other of the emergency slide and the door panel has a second guide hole for accommodating the second guide portion, the extension direction of the second guide hole is parallel to the sliding direction of the emergency slide, and the extension length of the second guide hole corresponds to the extension length of the second strip hole. The emergency turntable rotates to drive its second eccentric pin to move in the second strip hole and drive the emergency slide to slide horizontally, and at the same time the second guide portion slides along the second guide hole, thereby causing the locking mechanism to be emergency unlocked or emergency locked;

[0018] An extending direction of the second strip-shaped hole is substantially perpendicular to an extending direction of the second guide hole;

[0019] When the emergency motor is not started and unlocked, the second eccentric pin is located on the outer side of the center of the emergency turntable, and the second guide portion is close to the inner end of the second guide hole.

[0020] Like this, when main motor starts running, second guide part can stop the emergency slide plate from sliding to the right, also is conducive to main motor and maintains the position of needs at this moment. When emergency motor drives emergency slide plate to slide, second guide part can guide the sliding of emergency slide plate.

[0021] In order to ensure that the bolt head arm slides smoothly relative to the door panel, one of the bolt head arm and the door panel has a first guide portion, and the other of the bolt head arm and the door panel has a first guide hole for accommodating the first guide portion. The extension direction of the first guide hole is parallel to the sliding direction of the bolt head, and the extension length of the first guide hole corresponds to the extension length of the first strip hole. The main turntable rotates to cause the first guide portion to slide along the first guide hole.

[0022] When the box body and the door panel are in a locked state, the first eccentric pin of the main turntable is located on a side of the main turntable close to the bolt head, and the first guide portion is close to an end of the first guide hole away from the bolt head.

[0023] In this way, the bolt head arm can slide under the guidance of the first guide portion without being easily shaken or slipped off.

[0024] In order to stop the main motor after the bolt arm slides to a desired position, the door lock mechanism of the safe further includes a trigger unit and a control switch. The control switch is used to control the start and stop of the main motor and can be triggered by the trigger unit when the locking mechanism is in the unlocked state. The control switch is connected to a main controller, one of which is located on the bolt arm, and the other is located on the door panel. Thus, when the main motor is started and unlocked, when the bolt arm slides to a set position, the trigger unit triggers the control switch, causing the controller to stop the main motor.

[0025] Compared with the prior art, the present invention has the following advantages: by providing an emergency power supply, an emergency password input part, an emergency controller, an emergency motor and an emergency transmission structure, when emergency unlocking is required, the corresponding password is input into the emergency password input part, and after the emergency controller detects that the input password is correct, it starts the emergency motor to run, and the emergency motor causes the emergency slide to slide through the emergency transmission structure, thereby unlocking the locking mechanism. In this way, when emergency unlocking is required, there is no need to use an emergency key to open the emergency lock, and the corresponding password can be input into the emergency password input part. Therefore, there is no need to worry about the storage of the emergency key, and there is no risk of the emergency key being stolen, so the security is higher;

[0026] In addition, there is no problem of losing the emergency key and needing to find a locksmith to open it, so the safe will not be damaged and items can be taken out quickly; the emergency motor is used for emergency start, which has the advantage of convenient and quick operation.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 3 FIG. 1 is a preferred embodiment of a safe having a door lock mechanism of the present invention. The safe comprises a box body 5 and a door lock mechanism cooperating with the box body 5.

[0039] See also Figures 2 to 10The door lock mechanism of this safe includes a door panel 4, a main power supply (not shown), a master password input unit 22, a main controller 21, a locking mechanism 1, a trigger unit 133, a control switch 6, an emergency slide 31, an emergency power supply (not shown), an emergency password input unit 32, an emergency controller 33, an emergency motor 34, an emergency transmission structure, a balancing structure, etc. In this embodiment, the main password input unit 22 and the emergency password input unit 32 are located on the front of the door panel 4, and the remaining components are located on the back of the door panel 4. The main power supply (not shown in the figure; the main power supply can adopt existing technology, for example, it can be connected to an external power supply through the interface 23), the main password input unit 22, the main controller 21, the locking mechanism 1, the trigger unit 133, and the control switch 6 are the components of the main lock 2, while the emergency power supply (not shown in the figure), the emergency password input unit 32, the emergency controller 33, the emergency motor 34, and the emergency transmission structure are the components of the emergency lock 3.

[0040] The emergency power supply can be a standard mobile phone charger or power bank. The emergency power supply is plugged into the emergency port 36, which can be a USB port. The emergency power supply is used to power the emergency password input unit 32, the emergency controller 33, and the emergency motor 34. The emergency password input unit 32 is connected to the emergency controller 33, which in turn is connected to the emergency motor 34. The emergency controller 33 detects the correctness of the password entered into the emergency password input unit 32 and controls the activation of the emergency motor 34. The emergency motor 34 drives the emergency slide 31 to slide laterally via the emergency transmission structure.

[0041] The main password input part 22 and the emergency password input part 32 can be different parts. The main password input part 22 can be a fingerprint collector. In other embodiments, a password input keyboard, door card, or Bluetooth can also be used. The emergency password input part 32 can be a password input keyboard. The structure of the password input keyboard can adopt existing technology, for example, it has 1 to 9 numeric keys, "*", "#", etc., where * can be used as a lock button. In other embodiments, a fingerprint collector, door card, or Bluetooth can also be used. In other embodiments, the main password input part 22 and the emergency password input part 32 can also be the same part but correspond to different input instructions when starting the main motor 11 and the emergency motor 34. For example, the main password input part 22 and the emergency password input part 32 can use the same password input keyboard but correspond to different passwords.

[0042] The emergency slide plate 31 has a second strip-shaped hole 311 .

[0043] The emergency transmission structure includes an emergency turntable 35, whose second eccentric pin 351 extends into the second strip-shaped hole 311. Rotation of the emergency turntable 35 drives the second eccentric pin 351 to move within the second strip-shaped hole 311, thereby causing the emergency slide 31 to slide laterally. In other embodiments, the emergency turntable 35 can be replaced with a cam, and the emergency transmission structure can employ other mechanisms that convert the rotation of the output shaft of the emergency motor 34 into the sliding of the emergency slide 31, such as a rack and pinion structure. The emergency motor 34 can be connected to an emergency gear, which meshes with an emergency rack. The emergency rack is disposed on the emergency slide 31, and the direction of movement of the emergency rack aligns with the sliding direction of the emergency slide 31. The emergency transmission structure can also employ a worm gear mechanism.

[0044] The locking mechanism 1 includes a power unit, a main rotary disk 12, a bolt arm 13, and a bolt 14. The locking mechanism 1 is used to lock or unlock the door panel 4 and the housing 5. The main password input unit 22 is connected to the main controller 21, which is in turn connected to the power unit of the locking mechanism 1. The power unit of the locking mechanism 1 is mounted on the emergency slide 31 and includes a main motor 11 mounted on the emergency slide 31. The bolt 14 is connected to the bolt arm 13, which has a first slot 131. The main rotary disk 12 has a first eccentric pin 121, which extends into the first slot 131. Rotation of the main motor 11 drives the first eccentric pin 121 within the slot 131 and drives the bolt 14 laterally. In other embodiments, the main rotary disk 12 can be replaced with a cam, and the power unit of the locking mechanism 1 can also be an electromagnet that cooperates with the emergency slide 31.

[0045] Because the weight of the bolt head 14 and the bolt head arm 13 is generally greater than that of the emergency slide 31, or because the bolt head 14 has friction with the box body 5 during movement, or because the main motor 11 has a reaction effect on the emergency slide 31, the emergency slide 31 has a tendency to slide left and right (from Figure 5 (See) and exerting a force on the second eccentric pin 351, the second eccentric pin 351 is not likely to stay, and the emergency turntable 35 is likely to rotate. Then the second eccentric pin 351 acts in the opposite direction on the emergency slide 31, so that the main motor 11 cannot be stationary relative to the door panel 4 as expected, thus interfering with the start and unlocking of the main motor 11, and ultimately interfering with the locking and unlocking of the bolt head 14. Therefore, a balancing structure is designed. The balancing structure is used to prevent the emergency turntable 35 from rotating when the main motor 11 is running. When the emergency motor 34 is not running, the angle between the direction of the line connecting the center of the second eccentric pin 351 of the emergency turntable 35 and the rotation center 352 of the emergency turntable 35 and the sliding direction of the emergency slide 31 is β, see Figure 10, 0≤β≤10°, thus forming a balanced structure. In this embodiment, β is 0°, and the line connecting the center of the second eccentric pin 351 of the emergency turntable 35 and the rotation center 352 of the emergency turntable 35 is parallel to the sliding direction of the emergency slide 31. In other embodiments, β can also be set to 5° or 10° depending on the door lock mechanism. Furthermore, the door panel 4 has a second guide portion 42, and the emergency slide 31 has a second guide hole 312 for accommodating the second guide portion 42. The second guide hole 312 extends parallel to the sliding direction of the emergency slide 31, and the extension length of the second guide hole 312 corresponds to the extension length of the second strip hole 311. Rotation of the emergency turntable 35 drives its second eccentric pin 351 to move within the second strip hole 311, driving the emergency slide 31 to slide laterally. Simultaneously, the second guide portion 42 slides along the second guide hole 312, thereby enabling emergency unlocking or emergency locking of the locking mechanism 1. The extension direction of the second strip hole 311 is substantially perpendicular to the extension direction of the second guide hole 312. When the emergency motor 34 is not started and unlocked, the second eccentric pin 351 is located on the outer side of the center of the emergency turntable 35, and the second eccentric pin 351 is close to the first end 311a of the second strip hole 311 (see Figure 9 ,from Figure 5 The first end is the upper end of the second strip hole 311), and the second guide portion 42 is close to the inner end of the second guide hole 312. In this way, the second guide portion 42 has two functions: one is to guide the emergency slide 31 during its movement; the other is to prevent the emergency slide 31 from sliding to the right (from the left) when the main motor 11 is running. Figure 5 Like this, the emergency slide plate 31 and the main motor 11 are maintained in their original positions, that is, the emergency slide plate 31 and the main motor 11 are stationary relative to the door panel 4, preventing the emergency turntable 35 from rotating.

[0046] The door panel 4 also has a first guide portion 41, and the bolt arm 13 has a first guide hole 132 for accommodating the first guide portion 41. The first guide hole 132 extends parallel to the sliding direction of the bolt head 14, and the extension length of the first guide hole 132 corresponds to the extension length of the first strip hole 131. The main turntable 12 rotates to cause the first guide portion 41 to slide along the first guide hole 132. In other embodiments, the first guide portion 41 may be located on the bolt arm 13, while the first guide hole 132 is located on the door panel 4. When the housing 5 and door panel 4 are locked, the first eccentric pin 121 is located on the side of the main turntable 12 closest to the bolt head 14, and the first guide portion 41 is located near the end of the first guide hole 132 away from the bolt head 14.

[0047] The control switch 6 is used to control the start and stop of the main motor 11 and can be triggered by the trigger unit 133 when the locking mechanism 1 is in the unlocked state. The control switch 6 is connected to the main controller 21. The trigger unit 133 is located on the bolt head arm 13, and the control switch 6 is arranged on the door panel 4. In other embodiments, the trigger unit 133 can also be located on the door panel 4 and the control switch 6 can be located on the bolt head arm 13.

[0048] In this embodiment, the working principle and usage process of the door lock mechanism of the safe are as follows.

[0049] by Figure 4 It is the initial state, at this time the box body 5 and the door panel 4 are in a locked state, the second guide portion 42 is close to the side of the second guide hole 312 away from the bolt head 14, the first guide portion 41 is close to the side of the first guide hole 132 away from the bolt head 14, the first eccentric pin 121 is located on the right side of the main turntable 11 and close to one end of the first strip hole 131, and the second eccentric pin 351 is located on the right side of the emergency turntable 35 and close to the upper end of the second strip hole 311.

[0050] To open the door panel 4 under normal conditions, the user's finger acts on the main password input portion 22 (in this embodiment, the finger presses the fingerprint collector). The main controller 21 detects that the control switch 6 is in the untriggered state (that is, the control switch 6 and the trigger portion 133 are separated from each other, and the door panel 4 is in the closed state). The main controller 21 compares the fingerprint collected by the fingerprint collector with the pre-registered fingerprint texture. If the two match, the main controller 21 commands the main motor 11 to open the door. The main motor 11 then drives the main turntable 12 to rotate. The first eccentric pin 121 of the main turntable 12 slides in the first strip hole 131 and drives the bolt arm 13 to slide horizontally. The bolt head 14 on the bolt arm 13 then retracts horizontally, unlocking the door between the box body 5 and the door panel 4. Figures 4 to 8 The process is the process of unlocking the door panel 4 and the box body 5 by acting on the main password input part 22 under normal conditions. During this process, the position of the main motor 11 relative to the door panel 4 does not change.

[0051] When it is necessary to close the door panel 4 under normal conditions, similarly, the user's finger acts on the main password input part 22 (in this embodiment, it is a finger pressing fingerprint collector). At this time, the main controller 21 may not compare the collected fingerprint with the pre-recorded fingerprint texture. The main controller 21 detects that the control switch 6 is in the triggered state (that is, at this time the control switch 6 is against the trigger part 133, and the door panel 4 is in the open state). Then, the main controller 21 controls the main motor 11 to start, and the main motor 11 drives the main turntable 12 to rotate. The first eccentric pin 121 of the main turntable 12 slides in the first strip hole 131 and drives the bolt head arm 13 to slide horizontally. The bolt head 14 on the bolt head arm 13 then extends horizontally, thereby locking the box body 5 and the door panel 4. Figure 8 to Figure 4The process is that under normal conditions, after acting on the main password input part 22, the door panel 4 and the box body 5 are gradually locked. During this process, the position of the main motor 11 relative to the door panel 4 does not change.

[0052] When emergency unlocking of the door panel 4 is required, for example, when the main motor 11 fails and the box body 5 and the door panel 4 cannot be unlocked, the emergency unlocking can be performed by starting the emergency motor 34. Specifically, an emergency power supply such as a power bank is inserted through the emergency interface 36. After the emergency power supply is turned on, the emergency password input part 32 (the password input keyboard in this embodiment) on the operation panel lights up and displays the positions of 0 to 9, *, and #. After the user enters the keyboard password, the emergency controller 33 compares the input keyboard password with the stored keyboard password. If the comparison is successful, the emergency controller 33 will be turned off. 33 controls the emergency motor 34 to start, and the emergency motor 34 drives the emergency turntable 35 to rotate. The second eccentric pin 351 of the emergency turntable 35 slides in the second strip hole 311 and drives the emergency slide plate 31 to slide horizontally. The horizontal sliding of the emergency slide plate 31 drives the main motor 11 located on the emergency slide plate 31 to slide horizontally. Because the main motor 11, the main turntable 12, the bolt head arm 13, and the bolt head 14 are stationary relative to the emergency slide plate 31 at this time, the horizontal sliding of the emergency slide plate 31 eventually causes the bolt head 14 to slide horizontally and retract horizontally, thereby unlocking the box body 5 and the door panel 4.

[0053] When the emergency motor 34 is not started, the second eccentric pin 351 is close to the first end of the second strip hole 311 (that is, the top inner wall of the second strip hole 311, see Figure 5 ), see Figure 5 At this time, the direction of the line connecting the rotation center 352 of the emergency turntable 35 and the center of the second eccentric pin 351 is parallel to the sliding direction of the emergency slide 31. After the emergency motor 34 is started, Figure 5 As the emergency turntable 35 starts to rotate clockwise, the second eccentric pin 351 gradually moves downward. When the second eccentric pin 351 moves to the second end 311b of the second bar-shaped hole 311 (see FIG. Figure 9 ,from Figure 5 After the emergency turntable 35 continues to rotate clockwise, the second eccentric pin 351 continues to move upward. When the second eccentric pin 351 moves to the first end of the second strip hole 311 (see FIG. Figure 5 , that is, the top inner wall of the second strip hole 311) is offset, the emergency controller 33 detects the corresponding change in current and voltage and stops the emergency motor 34. At this time, see Figure 7 The extending direction of the line connecting the rotation center 352 of the emergency turntable 35 and the center of the second eccentric pin 351 is consistent with the sliding direction of the emergency slide plate 31 . Figures 4 to 6 process, Figures 5 to 7The processes are all in an emergency state, in which the door panel 4 and the box body 5 are unlocked by acting on the emergency password input part 32. During this process, the position of the main motor 11 relative to the door panel 4 changes.

[0054] If the main motor 11 is not repaired temporarily, starting the emergency motor 34 can also be used to lock the box body 5 and the door panel 4. Specifically: after the user presses the door closing button "*" in the emergency password input part 32, the emergency controller 33 controls the emergency motor 34 to start, and the emergency motor 34 drives the emergency turntable 35 to rotate. The second eccentric pin 351 of the emergency turntable 35 slides in the second bar hole 311 and drives the emergency slide plate 31 to slide horizontally. The horizontal sliding of the emergency slide plate 31 drives the main motor 11 located on the emergency slide plate 31 to slide horizontally together. Similarly, because the main motor 11, the main turntable 12, the bolt head arm 13, and the bolt head 14 are stationary relative to the emergency slide plate 31 at this time, when the emergency slide plate 31 slides horizontally, the bolt head 14 will eventually slide horizontally and extend horizontally, thereby locking the box body 5 and the door panel 4. Figure 6 to Figure 4 process, Figure 7 to Figure 5 The above processes are all in an emergency state. After the emergency code input part 32 is applied, the door panel 4 and the housing 5 are gradually locked. During this process, the position of the main motor 11 relative to the door panel 4 changes. In this way, if the main lock 2 fails, even if the main lock 2 is not repaired, the door panel 4 and the housing 5 can still be locked by the emergency lock 3, thereby ensuring the normal use of the safe and extending the service life of the safe.
