Description

Technical Field

[0001] The present application relates to the technical field of electronic door locks, and in particular to an electronic door lock with mechanical unlocking. Background Art

[0002] For electronic door locks commonly used in life, you first need to enter the correct digital password or fingerprint and other instructions. After the instruction is correct, you can turn the door handle to open the door. The door handle drives the lock core to rotate to open the door.

[0003] A locking member is usually provided in an electronic lock to lock or unlock the rotation of the lock cylinder. However, the internal space of the lock is small and the distance the locking member is driven is limited. If the locking member moves too far, it is easy to damage the lock cylinder. In the existing technology, it is generally driven directly by a motor and a screw rod, and the movement distance of the locking member is closely related to the speed of the motor and the pitch of the screw rod. The smaller the speed and pitch, the smaller the movement distance of the locking member. However, the smaller the speed and pitch, the greater the difficulty in designing, which greatly increases the production cost of the electronic lock. Therefore, it is not possible to reconcile reducing the risk of the lock cylinder being hit and the production cost of the electronic lock. Summary of the Invention

[0004] In order to reduce the risk of the lock core being hit and the production cost of the electronic lock at the same time, the present application provides an electronic door lock with mechanical unlocking.

[0005] This application provides a mechanically unlocked electronic door lock that adopts the following technical solution:

[0006] A mechanically unlocked electronic door lock comprises a lock body, a lock core, a locking member, and a driving device for driving the locking member to move, wherein the driving device comprises:

[0007] A moving part, slidably arranged on the lock body;

[0008] A driving assembly, used for driving the moving part to move;

[0009] An elastic component is provided on the locking member and is inserted and installed on the lock body for positioning under the action of elastic force;

[0010] The pushing component is arranged on the moving part and is located on both sides of the elastic component. After the moving part moves for a period of time, the elastic component is pushed to separate from the lock body through the pushing component. The pushing component pushes the elastic component to move at the same time until the locking part is plugged and installed on the lock core for positioning. The moving part moves back and pushes the elastic component and the locking part back through the pushing component until the elastic component is plugged and installed on the lock body for positioning and is used to unlock the lock core.

[0011] By adopting the above technical solution, when the lock cylinder needs to be locked, the driving component starts to drive the moving part to move, and the moving part drives the pushing component to approach the elastic component. The pushing component first pushes the elastic component away from the lock body to unlock, and then the pushing component moves to push the elastic component and the locking part close to the lock body, so that the locking part is plugged and installed on the lock body for positioning, thereby achieving locking of the lock cylinder; when unlocking is required, the driving component starts to drive the moving part to move back, and the moving part pushes the elastic component back through the pushing component. The elastic component is plugged and installed on the lock body for positioning under the action of elastic force, and then the moving part and the pushing component move away from the elastic component until they move back to their original position, and then the door handle can be turned to complete the door opening.

[0012] The pushing component moves for a period of time and then contacts the elastic component. The pushing component then pushes the elastic component to unlock the lock, and then the pushing component, elastic component and locking member move at the same time. Therefore, under the condition of the same parameters of the driving component, the distance the driving component starts to push the locking member to move is greatly reduced, which can simultaneously reduce the risk of the lock core being hit and the production cost of the electronic lock.

[0013] When locking the lock cylinder, the driving component positions the locking part through the pushing component and the elastic component, thereby improving the locking effect of the lock cylinder. At the same time, the elastic component positions the locking part when unlocking the lock cylinder, and the moving part automatically unlocks after moving, making the unlocking structure simpler and further reducing the production cost of the electronic lock.

[0014] Optionally, the elastic component includes:

[0015] A locking rod is slidably arranged on the locking member in a direction perpendicular to the sliding direction of the locking member;

[0016] The spring is arranged on the locking member and connected to the locking rod so that the locking rod is inserted and installed on the lock body for positioning.

[0017] By adopting the above technical solution, the spring pushes the locking rod to be installed on the lock body for positioning, the pushing component first pushes the locking rod to move to unlock, and then pushes the component against the locking rod to push the locking rod and the locking piece to move at the same time. During the movement of the locking rod, the spring continues to push the locking rod against the lock body to position the locking piece in real time, thereby reducing the risk of the locking piece falling and hitting the lock core, and further reducing the risk of the lock core being hit.

[0018] Optionally, the pushing component includes:

[0019] Pushing block 1 is provided on the movable member and is located on the side of the locking rod facing away from the lock cylinder;

[0020] Pushing block 2 is provided on a side wall of the locking rod near one end of the movable member and near the pushing block 1 side, the pushing block 1 and the pushing block 2 respectively forming a pushing surface 1 and a pushing surface 2 which can abut against each other and are in an inclined state, the pushing block 1 is further provided with a contact surface which abuts against the locking rod, the pushing block 1 moves so that the pushing surface 1 and the pushing surface 2 abut against each other and are used to push the locking rod away from the lock body, the pushing block 1 continues to move so that the contact surface abuts against the locking rod and pushes the locking rod and the locking member to move simultaneously;

[0021] The push-back member is arranged on the moving member and is located on a side of the locking rod away from the pushing block. The moving member moves back and pushes the locking rod back through the push-back member until the locking rod is inserted and installed on the lock body for positioning.

[0022] By adopting the above technical solution, the moving part moves and pushes the pushing block 1 close to the pushing block 2, so that the pushing surface 1 and the pushing surface 2 are fitted together. The moving part continues to move and pushes the locking rod away from the lock body and then disengages from the lock body, and makes the fitting surface rest on the locking rod, so that the pushing surface 1 and the pushing surface 2 do not move relative to each other. The moving part continues to move and pushes the locking rod and the locking part to move at the same time. Since the spring makes the locking rod maintain the tendency to move back, the pushing block 2 can be moved away from the pushing block 1. Under the action of the spring, the locking rod can be pressed against the lock for positioning, thereby reducing the risk of the locking part falling and hitting the lock cylinder, and further reducing the risk of the lock cylinder being hit.

[0023] When the moving part moves back, the moving part pushes the locking rod and the locking part back through the push-back part, until the locking rod is plugged and installed on the lock body for positioning under the action of the elastic component. The push-back part abuts against the locking rod, so that the push-back part does not block the locking rod from moving back and is plugged into the lock body, thereby driving the locking rod and the locking part to move as required.

[0024] Optionally, the pushback member includes:

[0025] A moving portion is provided on the moving member and is located on a side of the locking rod away from the pushing block;

[0026] The positioning portion is arranged on the locking rod; when the locking rod is plugged and installed on the lock body, the moving portion abuts against the positioning portion and the locking rod and is used to prevent the locking rod from detaching from the lock body; the moving member moves to drive the moving portion to detach from the positioning portion, the pushing surface one and the pushing surface two fit together and are used to push the locking rod to detach from the lock body, and when the moving member moves back, the moving portion is driven to abut against the positioning portion and push the locking rod and the locking member to move back at the same time.

[0027] By adopting the above technical solution, when locking is required, the moving part moves to drive the moving portion away from the locking rod and the positioning portion, so that the moving portion is disengaged from the locking rod and the positioning portion, the pushing surface one and the pushing surface two fit together and push the locking rod to move, and the movement of the locking rod also drives the positioning portion close to the moving portion, thereby driving the locking rod and the locking part to move close to the lock core at the same time, so that the locking part is inserted and installed on the lock core for positioning.

[0028] When unlocking is required, the moving part moves back, causing the moving part to abut against the end of the positioning part away from the locking rod, pushing the locking rod and the locking part back until the locking rod is plugged into the lock body for positioning. The locking rod moves to drive the positioning part away from the moving part, and the moving part can continue to move, causing the moving part to abut against the side wall of the locking rod and the positioning part away from the connection between the locking rod and the lock body for positioning, thereby positioning the locking rod position by the moving part, and improving the positioning effect of the locking rod on the locking part.

[0029] Optionally, the pushing block 1 and the push-back member are both arranged on the movable member through an adjusting component, and the adjusting component is used to adjust the positions of the pushing block 1 and the push-back member along the sliding direction of the locking member.

[0030] By adopting the above technical solution, the adjustment component is used to adjust the position of the push block 1 and the push-back member, thereby being able to drive the locking members with different distance requirements.

[0031] Optionally, the adjustment component includes:

[0032] The adjusting block is slidably arranged on the moving member along the sliding direction of the locking member, and the pushing block is detachably arranged on the adjusting block through a connecting assembly;

[0033] The locking piece is arranged on the adjusting block and is used to locate the position of the adjusting block.

[0034] By adopting the above technical solution, the locking member is unlocked, the adjusting block moves the adjusting push block to a position, and after the adjustment is completed, the locking member locks the adjusting block and the push block to a position.

[0035] Optionally, the locking member is a locking screw that is threadedly connected to the adjustment block and presses against the moving member for positioning.

[0036] Optionally, the connection component includes:

[0037] The connecting block is arranged on the pushing block and is plugged and installed on the adjusting block for positioning;

[0038] The connecting screw passes through the pushing block and is threadedly connected to the adjusting block for positioning.

[0039] By adopting the above technical solution, the connecting block is plugged and installed on the adjusting block to realize the positioning of the push block 1, and then the connecting screw is passed through the push block 1 thread and connected to the adjusting block for positioning, thereby realizing the replacement of the push block 1.

[0040] Optionally, the driving component includes:

[0041] A screw rod is rotatably mounted on the lock body and is threadedly connected to the moving part;

[0042] The motor is arranged on the lock body and is used to drive the screw to rotate.

[0043] By adopting the above technical solution, the motor drives the screw rod to rotate, and the rotation of the screw rod drives the moving part to move.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. The pushing component moves for a period of time and then contacts the elastic component. The pushing component then pushes the elastic component to unlock the lock, and then the pushing component, the elastic component and the locking component move simultaneously. In this way, under the condition of the same parameters of the driving component, the moving distance of the driving component when the driving component starts to push the locking component is greatly reduced, which can simultaneously reduce the risk of the lock core being hit and the production cost of the electronic lock.

[0046] 2. When locking the lock cylinder, the driving component positions the locking member through the pushing component and the elastic component, thereby improving the locking effect of the lock cylinder. At the same time, the elastic component positions the locking member when unlocking the lock cylinder, and the moving member automatically unlocks after moving, making the unlocking structure simpler and further reducing the production cost of the electronic lock.

[0051] The following is a further detailed description of this application.

[0052] The embodiment of the present application discloses an electronic door lock with mechanical unlocking.

[0053] Reference Figure 1 and Figure 2 The mechanically unlocked electronic door lock includes a lock body 1, a lock cylinder 11, a locking member 12, and a driving device 2 for driving the locking member 12 to move. The lock cylinder 11 is rotatably mounted on the lock body 1, and the locking member 12 is slidably arranged on the lock body 1 in a direction close to or away from the lock cylinder 11; the driving device 2 is used to drive the locking member 12 to move, so that the locking member 12 is plugged and installed on the lock cylinder 11 to lock, thereby achieving locking, or the driving device 2 drives the locking member 12 to disengage from the lock cylinder 11, thereby achieving unlocking, and then the door handle can be turned to open the door.

[0054] The locking member 12 includes a sliding portion 121 that is slidably mounted on the lock body 1 and a plug-in portion 122 that is fixedly mounted on the movable portion 51. The plug-in portion 122 is used to plug and cooperate with the lock core 11 for locking. The plug-in portion 122 can be set with different parameters such as size and shape as needed to meet the requirements of plugging and cooperating with the lock core 11 for locking.

[0055] The driving device 2 includes a moving part 21, a driving component 22, an elastic component 3 and a pushing component 4. The moving part 21 is slidably arranged on the lock body 1 in a direction close to or away from the lock cylinder 11. The moving part 21 is located on one side of the sliding part 121 and the sliding direction is parallel to the sliding direction of the sliding part 121; the driving component 22 is used to drive the moving part 21 to move, the elastic component 3 is arranged on the sliding part 121, and the elastic component 3 is inserted and installed on the lock body 1 under the action of elastic force for positioning.

[0056] The pushing component 4 is arranged on the moving part 21 and is located on both sides of the elastic component 3. After the moving part 21 moves for a period of time, the elastic component 3 is pushed to disengage from the lock body 1 through the pushing component 4. The pushing component 4 pushes the elastic component 3 to move at the same time until the plug-in part 122 is plugged into the lock cylinder 11 for positioning, thereby achieving locking; when unlocking is required, the moving part 21 moves back and pushes the elastic component 3 and the locking part 12 to move back through the pushing component 4 until the elastic component 3 is plugged into the lock for positioning, thereby unlocking the lock cylinder 11, and then the door handle can be turned to open the door.

[0057] The driving assembly 22 includes a screw rod 23 and a motor 24. The screw rod 23 is rotatably mounted on the lock body 1 and is threadedly connected to the movable member 21. The motor 24 is fixedly mounted on the lock body 1, and the output shaft of the motor 24 is fixedly connected to the screw rod 23. When the motor 24 is started, the screw rod 23 is driven to rotate, and the screw rod 23 rotates to drive the movable member 21 to move.

[0058] Reference Figure 1-Figure 3 When the cam 31 is in the unlock state, the locking plate 33 is locked and the locking piece 33 is fixed to the locking plate 31. The cam 31 is in the unlock state, and the locking piece 33 is fixed to the locking plate 31.

[0059] The pushing assembly 4 includes a pushing block 1 41, a pushing block 2 42, and a push-back member 5. The pushing block 1 41 includes a fixed portion 43 and a pushing portion 44. The fixed portion 43 is installed on the side wall of the moving member 21 close to the locking rod 31, and the length direction of the fixed portion 43 is parallel to the sliding direction of the locking rod 31. The pushing portion 44 is fixedly installed on one end of the fixed portion 43 close to the locking rod 31, and the pushing portion 44 is located on the side wall of the fixed portion 43 close to the locking rod 31. A fitting surface 45 for fitting with the locking rod 31 is formed on the side wall of the pushing portion 44 close to the locking rod 31.

[0060] The second pushing block 42 is fixedly mounted on one end of the locking rod 31 close to the moving member 21, and the second pushing block 42 is located on the side wall of the locking rod 31 close to the pushing portion 44. The side wall of the pushing portion 44 close to the moving member 21 is provided with an inclined pushing surface 1 46, and the end of the pushing block 2 42 close to the pushing portion 44 is provided with an inclined pushing surface 2 47, and the pushing surface 1 46 and the pushing surface 2 47 are parallel; the moving member 21 drives the pushing block 1 41 to approach the pushing block 2 42, so that the pushing surface 1 46 and the pushing surface 2 47 fit together. The moving member 21 continues to move to push the locking rod 31 out of the fixed groove, and makes the fitting surface 45 close to the locking rod 31, thereby pushing the locking rod 31 and the locking member 12 to approach the lock cylinder 11 at the same time.

[0061] The push-back member 5 is fixedly mounted on the side wall of the moving member 21 close to the locking rod 31. The push-back member 5 and the pushing block 41 are located on both sides of the locking rod 31, and the push-back member 5 is located on the side of the locking rod 31 close to the lock cylinder 11. The moving member 21 moves back through the push-back member 5 to push the locking rod 31 back, and until the locking rod 31 is inserted and installed on the lock body 1 for positioning. The push-back member 5 includes a moving portion 51 and a positioning portion 52. The moving portion 51 is installed on the side wall of the moving member 21 close to the locking rod 31, and the moving portion 51 is inclined toward the locking rod 31, and the positioning portion 52 is fixedly installed on the side wall of the locking rod 31 close to the moving portion 51; when the locking rod 31 is inserted and installed on the fixed groove for positioning, the moving portion 51 abuts against the side wall of the positioning portion 52 close to the moving member 21, thereby preventing the locking rod 31 from detaching from the fixed groove, and the moving portion 51 also abuts against the locking rod 31 for positioning, further reducing the risk of the locking rod 31 detaching from the fixed groove due to the gravity of the locking rod 31 and the sliding portion 121.

[0062] The moving part 21 moves to drive the moving part 51 to disengage from the positioning part 52, and the pushing block 1 41 and the pushing block 2 42 cooperate to push the locking rod 31 to disengage from the fixed groove. When the moving part 21 moves back, it drives the moving part 51 to move back, and the moving part 51 rests on the side wall of the positioning part 52 away from the locking rod 31 to push the locking rod 31 and the sliding part 121 to move back.

[0063] When locking is required, the movable member 21 moves to drive the pushing block 1 41 close to the pushing block 2 42 and the moving part 51 moves away from the positioning part 52. After the movable member 21 moves for a period of time, the moving part 51 is disengaged from the positioning part 52 and the pushing surface 1 46 and the pushing surface 2 47 are in contact with each other, and then the moving member 21 continues to move, that is, the locking rod 31 is driven away from the fixed plate 13 and the locking rod 31 is disengaged from the fixed groove. Then the contact surface 45 is in contact with the locking rod 31 and pushes the locking rod 31 and the sliding part 121 close to the lock cylinder 11, so that the plug-in part 122 is plugged into the lock cylinder 11 for locking. At the same time, during the pushing process, the spring 32 pushes the locking rod 31 to maintain the tendency to approach the fixed plate 13, so that the sliding part 121, the locking rod 31 and the pushing block 2 42 are all away from the pushing block 1 41 under the action of the spring 32, so that the locking rod 31 can be moved back and pressed against the fixed plate 13 for positioning under the action of the spring 32, thereby reducing the risk of the sliding part 121 falling directly and hitting the lock cylinder 11.

[0064] When unlocking is required, the moving part 21 drives the moving part 51 to approach the positioning part 52 and the pushing block 1 41 away from the pushing block 2 42, the pushing block 1 41 and the pushing block 2 42 are disengaged, and the moving part 51 abuts against the positioning part 52 and pushes the locking rod 31 and the sliding part 121 to move back until the locking rod 31 is inserted and installed in the fixed groove for positioning under the action of the spring 32. At the same time, the locking rod 31 moves during the insertion process and drives the positioning part 52 to move, so that the positioning part 52 and the moving part 51 are misaligned. The moving part 51 can continue to move up and abut against the positioning part 52 and the locking rod 31 for positioning, thereby preventing the locking rod 31 from disengaging from the fixed groove.

[0065] The pushing block 41 and the push-back member 5 are both arranged on the moving member 21 through the adjusting component 6, and the adjusting component 6 is used to adjust the position of the pushing block 41 and the push-back member 5 along the sliding direction of the sliding part 121; the following is explained using the adjusting component 6 connected to the pushing block 41 as an example.

[0066] The adjusting assembly 6 includes an adjusting block 61 and a locking piece 62. The adjusting block 61 is slidably installed on the side wall of the movable member 21 close to the locking rod 31 along the sliding direction of the sliding portion 121. The pushing block 41 is detachably installed on the side wall of the adjusting block 61 close to the locking rod 31 through the connecting assembly 7; the locking piece 62 is arranged on the adjusting block 61 and is used to position the position of the adjusting block 61. The locking piece 62 can be a locking screw connected to the adjusting block 61 by a screw, and the locking screw presses against the movable member 21 for positioning.

[0067] The connecting assembly 7 includes a connecting block 71 and a connecting screw 72. The connecting block 71 is fixedly mounted on the fixing portion 43 and plugged into the adjusting block 61 for positioning. The connecting screw 72 passes through the fixing portion 43 and is threadedly connected to the adjusting block 61 for positioning, thereby realizing the replacement of the pushing block 41 and the push-back member 5.

[0068] The working principle of the embodiment of this application is as follows:

[0069] When locking is required, the moving part 21 moves to drive the pushing block 1 41 and the moving part 51 to move, so that the moving part 51 is disengaged from the positioning part 52 and the pushing surface 1 46 and the pushing surface 2 47 are fitted together, driving the locking rod 31 to disengage from the fixed groove, and then the fitting surface 45 is fitted together with the locking rod 31 and pushes the locking rod 31 and the sliding part 121 close to the lock core 11, so that the plug-in part 122 is plugged and installed on the lock core 11 for locking.

[0070] When unlocking is required, the moving part 21 drives the pushing surface 1 46 and the pushing surface 2 47 to disengage, and the moving part 51 abuts against the positioning part 52 to push the locking rod 31 and the sliding part 121 back until the locking rod 31 is inserted and installed in the fixed groove for positioning under the action of the spring 32. At the same time, when the locking rod 31 moves, it drives the positioning part 52 to move, so that the positioning part 52 and the moving part 51 are misaligned. The moving part 51 can continue to move upward and abut against the positioning part 52 and the locking rod 31 for positioning, thereby preventing the locking rod 31 from disengaging from the fixed groove, thereby reducing the risk of the lock cylinder 11 being hit and the production cost of the electronic lock.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
