Description

Technical Field

[0001] This application relates to the field of lock technology, specifically to auxiliary door closing devices and smart locks. Background Technology

[0002] Currently, security locks are divided into fully mechanical security locks and fully automatic smart locks. Fully mechanical security locks are becoming increasingly unsuitable for modern people's lifestyles due to the inconvenience of opening them, and have been gradually replaced by fully automatic smart locks.

[0003] Fully automatic smart locks are becoming increasingly popular. To improve the sealing and sound insulation of the door, a sealing strip is installed on the door. However, when closing the door, the sealing strip is prone to popping open the door. When the closing force is too weak, the end of the slanted latch is pressed against the door frame and trapped inside the lock case, unable to be inserted into the socket on the door frame. This results in the door being partially ajar, meaning the door is not in the locked position, which is a serious problem that allows thieves to enter without unlocking. Utility Model Content

[0004] In view of this, this application provides an auxiliary door closing device and a smart lock to solve or improve the problem of accidentally leaving the door open.

[0005] In a first aspect, this application provides an auxiliary door closing device, including a door closing assembly and a sliding assembly disposed on the door body;

[0006] The closing assembly is rotatably connected to the sliding assembly, and the sliding assembly can drive the closing assembly to slide closer to or away from the door frame in a first direction, so as to be suitable for abutting or disengaging from the abutting part provided on the door frame.

[0007] In this embodiment, when a user needs to lock the door before leaving, they rotate the door so that it is inside the door frame. At this time, the sealing strip on the door contacts the door frame, and the door is in a slightly ajar position. This means the latch of the door lock is pressed against the door frame and retracts into the lock, but the door is not yet in the locked position, and the latch cannot be inserted into the latch hole. At this point, the sliding assembly slides along the first direction, approaching the door frame. The closing assembly abuts against the abutment part and rotates on the sliding assembly, moving the abutment part and driving the door to rotate along the closing direction, thus moving the door to the locked position. This allows the latch to be inserted into the latch hole, completing the locking action.

[0008] In one alternative implementation, the door closing assembly includes:

[0009] A door closing lever, which is rotatably connected to the sliding assembly, is adapted to abut against the abutment portion;

[0010] A first actuating block is connected to the closing actuating block and arranged at an angle; the first actuating block extends obliquely along the direction of the sliding assembly near the abutment, and an abutment is provided on the door body, the first actuating block being adapted to abut against the abutment.

[0011] In one alternative embodiment, a drive mechanism is further included, which is mounted on the door body;

[0012] The sliding component includes:

[0013] A sliding plate, which is slidably connected to the door body, and a driving mechanism that is transmissionally connected to the sliding plate;

[0014] At least one connecting plate is provided, the connecting plate being connected to the sliding plate, and the door closing toggle block is rotatably connected to the connecting plate.

[0015] In one optional embodiment, the door closing lever is provided with at least one connecting lug, the connecting lug having a through hole, and a pin passing through the through hole and connected to the connecting plate, so that the door closing lever is rotatably connected to the connecting plate.

[0016] In one alternative embodiment, the pin is parallel to the rotation axis of the door body.

[0017] In one alternative implementation, it further includes:

[0018] A housing is disposed on the door body. A through hole is provided on the side plate of the housing. The through hole is adapted to correspond to the abutment part. A sliding plate is slidably connected inside the housing. A door closing lever is adapted to pass through the through hole. The drive mechanism is installed inside the housing.

[0019] The abutment is a side plate with the perforation in the housing.

[0020] In one optional embodiment, the door frame has a groove corresponding to the closing lever. When the door is close to the lever, the closing lever is inserted into the groove. When the door is far away from the lever, the closing lever is away from the groove. The groove wall where the closing lever abuts against the groove is the abutting part.

[0021] In one optional implementation, the drive mechanism includes:

[0022] A drive motor is disposed inside the housing, and the output shaft of the drive motor is coaxially connected to a screw via a coupling, the screw extending along the first direction;

[0023] The sliding assembly also includes a fixing plate, which is fixed on the sliding plate. The fixing plate has a mounting hole corresponding to the screw, and a nut that matches the screw is fixedly connected in the mounting hole. The screw and the nut are connected in a driving connection.

[0024] In one alternative implementation, the first toggle block and the door closing toggle block are set at an acute angle.

[0025] Secondly, this application also provides a smart lock, comprising:

[0026] Auxiliary door closing device;

[0027] A lock housing is disposed on the door body, and a sliding assembly is disposed inside the lock housing. The lock housing has a through hole corresponding to the closing assembly, and the through hole is adapted to correspond to the abutment portion.

[0042] Currently, security locks are divided into fully mechanical security locks and fully automatic smart locks. Fully mechanical security locks are becoming increasingly unsuitable for modern people's lifestyles due to the inconvenience of opening them, and have been gradually replaced by fully automatic smart locks.

[0043] With the increasing popularity of fully automatic smart locks, sealing strips are installed on doors to improve their sealing and sound insulation. However, when closing the door, these strips can easily spring open. If the closing force is too weak, the end of the latch rests against the door frame and is pressed into the lock housing, preventing it from inserting into the latch hole on the door frame. This results in the door being partially ajar, meaning it's not in the locked position, making it easy for thieves to enter without unlocking. Therefore, this application provides an auxiliary closing device and a smart lock to solve or improve the problem of accidentally leaving the door ajar.

[0044] The following is combined Figures 1 to 5 This describes an embodiment of the present application.

[0045] According to embodiments of this application, in one aspect, an auxiliary door-closing device is provided, such as... Figures 1 to 4 As shown, an auxiliary door closing device is installed on the door body, and the door body is rotatably installed on the door frame 1. The door frame 1 has an abutment part 101 corresponding to the auxiliary door closing device. The auxiliary door closing device includes a door closing assembly 3 and a sliding assembly 2 installed on the door body. The door closing assembly 3 is rotatably connected to the sliding assembly 2, and the sliding assembly 2 can drive the door closing assembly 3 to slide closer to or away from the door frame 1 along the first direction X, so as to abut or disengage from the abutment part 101 installed on the door frame 1.

[0046] In this embodiment, when a user needs to lock the door before leaving, they rotate the door so that it is inside the door frame 1. At this time, the sealing strip on the door contacts the door frame 1. Under the elastic force of the sealing strip, the door needs to be pushed to reach the locked position. For example, in one application scenario, when a child closes the door, due to lack of experience and strength, the door is in a half-closed position. That is, the angled latch of the door lock is squeezed by the door frame 1 and retracts into the door lock, but the door is not in the locked position, and the angled latch cannot be inserted into the latch hole. At this time, the sliding component 2 slides along the first direction X, closes the door frame 1, and the closing component 3 abuts against the abutment part 101. The closing component 3 rotates on the sliding component 2, moving the abutment part 101, thereby driving the door to rotate along the closing direction, moving the door to the locked position, so that the angled latch is inserted into the latch hole, completing the locking action.

[0047] In one embodiment, such as Figure 1 As shown, the door closing assembly 3 includes:

[0048] The door closing toggle block 301 is rotatably connected to the sliding assembly 2 and is adapted to abut against the abutment part 101.

[0049] The first toggle block 302 is connected to the door closing toggle block 301 and arranged at an angle; the first toggle block 302 extends obliquely along the sliding assembly 2 near the abutment part 101, and the door body is provided with an abutment member 502, and the first toggle block 302 is adapted to abut against the abutment member 502.

[0050] Among them, an abutment 502 is provided on the door body along the direction of the sliding component 2 near the abutment part 101.

[0051] In this embodiment, such as Figure 1 and Figure 2 As shown, the first actuating block 302 is connected to the closing actuating block 301. Actuating the first actuating block 302 rotates the closing actuating block 301. During the process of assisting the closing device in closing the door, the sliding assembly 2 is driven to approach the abutment part 101 along the first direction X, so that the closing actuating block 301 abuts against the abutment part 101. At this time, the first actuating block 302 and the abutment part 502 are just in contact, that is, there is no pressure contact. The sliding assembly 2 continues to approach the abutment part 101 along the first direction X. At this time, the first actuating block 302, under the blocking action of the abutment part 502, causes the closing actuating block 301 to rotate on the sliding assembly 2. The closing actuating block 301 and the abutment part 101 are fixed in position because the abutment part 101 is set on the door frame 1. Then the closing actuating block 301 drives the door body to rotate to the locked position, and the oblique lock tongue is inserted into the lock tongue hole to complete the locking action.

[0052] The first actuating block 302 is inclined so that when the closing actuating block 301 moves a short distance along the sliding component 2, it abuts against the abutting member 502 and rotates, thereby squeezing the abutting part 101 and driving the door to rotate.

[0053] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes a drive mechanism 4, which is installed on the door body;

[0054] Sliding component 2 includes:

[0055] Sliding plate 201 is slidably connected to the door body, and driving mechanism 4 is connected to sliding plate 201 in a transmission manner;

[0056] At least one connecting plate 202 is connected to the sliding plate 201, and the door closing toggle block 301 is rotatably connected to the connecting plate 202.

[0057] In some embodiments, such as Figure 4As shown, there are two connecting plates 202, which are spaced apart and arranged in parallel. An installation space 10 is formed between the two connecting plates 202. The closing toggle block 301 is provided with a rotating part, which is located in the installation space 10 and is rotatably connected to the two connecting plates 202, thereby improving the stability of the rotation of the closing toggle block 301. The driving mechanism 4 can drive the sliding plate 201 to slide, thereby driving the closing toggle block 301 to abut against the abutment part 101 and driving the closing toggle block 301 to rotate.

[0058] In one embodiment, such as Figure 4 As shown, the door closing lever block 301 is provided with at least one connecting ear 303, and the connecting ear 303 is provided with a through hole. The pin 304 passes through the through hole and is connected to the connecting plate 202 so that the door closing lever block 301 is rotatably connected to the connecting plate 202.

[0059] In some embodiments, such as Figure 4 As shown, there are two connecting ears 303, which are spaced apart on the rotating part. The pin 304 passes through the through holes on the two connecting ears 303 and is rotatably connected to the through holes. The two ends of the pin 304 are fixedly connected to the two connecting plates 202 respectively.

[0060] In some implementations, along the first direction X, such as Figure 1 and Figure 2 As shown, the through hole is located on the side of the first actuating block 302 away from the abutment portion 101.

[0061] In one embodiment, the pin 304 is parallel to the rotation axis of the door.

[0062] In this embodiment, the pin 304 is parallel to the rotation axis of the door, which ensures that the rotation of the closing toggle block 301 can drive the door to rotate, thus avoiding the problem of jamming when the closing toggle block 301 drives the door to rotate.

[0063] In one embodiment, such as Figure 1 and Figure 2 As shown, it also includes:

[0064] The housing 5 is installed on the door body. A through hole 501 is provided on the side plate of the housing 5. The through hole 501 is adapted to correspond to the abutment part 101. The sliding plate 201 is slidably connected inside the housing 5. The door closing toggle block 301 is adapted to pass through the through hole 501. The drive mechanism 4 is installed inside the housing 5.

[0065] The abutment 502 is a side plate with a perforation 501 in the housing 5.

[0066] In this embodiment, such as Figure 1 and Figure 2As shown, the sliding plate 201, the door closing lever block 301, and the drive mechanism 4 are all installed inside the housing 5, which facilitates the installation of the above components and protects them.

[0067] In one embodiment, the door frame 1 has a groove corresponding to the closing lever 301. When the door is close to the groove, the closing lever 301 is inserted into the groove. When the door is far away from the groove, the closing lever 301 is away from the groove. The groove wall where the closing lever 301 abuts against the groove is the abutting part 101.

[0068] In this embodiment, such as Figure 1 and Figure 2 As shown, when the door is ajar, the closing lever 301 corresponds to the groove opening. When close, the closing lever 301 first inserts into the groove and abuts against the inner wall of the groove. As the depth of the closing lever 301 inserted into the groove increases, the first lever 302, under the blocking action of the abutment 502, causes the closing lever 301 to rotate on the sliding assembly 2. The closing lever 301 slides against the inner wall of the groove and extends into the bottom of the groove. The closing lever 301 moves the door to the locked position.

[0069] The groove provides clearance for the movement of the door closing lever 301.

[0070] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive mechanism 4 includes:

[0071] A drive motor 401 is installed inside the housing 5. The output shaft of the drive motor 401 is coaxially connected to a screw 6 via a coupling. The screw 6 extends along the first direction X.

[0072] The sliding assembly 2 also includes a fixing plate 203, which is fixed on the sliding plate 201. The fixing plate 203 has a mounting hole corresponding to the screw 6, and a nut that matches the screw 6 is fixedly connected in the mounting hole. The screw 6 and the nut are connected in a transmission connection.

[0073] In some implementations, the drive motor 401 may be selected with a planetary reduction gear mechanism.

[0074] In one embodiment, such as Figure 1 and Figure 2 As shown, the first toggle block 302 and the door closing toggle block 301 are set at an acute angle.

[0075] In this embodiment, when the closing toggle block 301 moves a short distance along the sliding assembly 2, it rotates by abutting the abutting member 502 through the first toggle block 302, thereby actuating the abutting part 101.

[0076] According to embodiments of this application, on the other hand, such as Figures 3 to 5 As shown, a smart lock is also provided, including: an auxiliary door closing device, a lock housing 7, a slanted locking tongue mechanism 8, a triggering tongue mechanism 9, and a controller.

[0077] Specifically, the lock housing 7 is installed on the door body, the sliding component 2 is installed inside the lock housing 7, and the lock housing 7 has a through hole 501 corresponding to the closing component 3. The through hole 501 is adapted to correspond to the abutment part 101. The oblique locking tongue mechanism 8 is installed inside the lock housing 7. The trigger tongue mechanism 9 is installed inside the lock housing 7. The controller is electrically connected to the drive mechanism 4, the electrical control part of the oblique locking tongue mechanism 8 and the electrical control part of the trigger tongue mechanism 9 respectively.

[0078] In this embodiment, when a user needs to lock the door before leaving, they rotate the door so that it is inside the door frame 1. At this time, the sealing strip on the door contacts the door frame 1. Under the action of the elasticity of the sealing strip, the door needs to be pushed to reach the locked position. When closing the door, if care is not taken or insufficient force is applied, the door can easily be left in a half-closed position. That is, the trigger tongue in the trigger tongue mechanism 9 and the oblique locking tongue in the oblique locking tongue mechanism 8 are squeezed by the door frame 1 and retract into the lock housing 7. However, the door has not reached the locked position, and the oblique locking tongue cannot be inserted into the socket. The trigger tongue in the trigger tongue mechanism 9 retracts into the lock housing 7. At this time, the trigger tongue mechanism 9 sends a signal to the controller indicating that the door is in a half-closed state. The controller then controls the drive motor 401 to drive the closing toggle block 301 to insert into the groove and drive the door to rotate. This process includes the drive motor 401 driving the sliding plate 201 to slide to the left along the first direction X and causing the closing toggle block 301 to insert into the groove and abut against the inner wall of the groove. At this time, the closing toggle block 301 is in the position as shown in the figure. Figure 1 In the prepared state shown, the drive motor 401 drives the sliding plate 201 to continue sliding to the left along the first direction X. Under the blocking action of the abutment member 502, the first actuating block 302 causes the closing actuating block 302 to rotate around the pin 304 on the connecting plate 202, while continuing to extend into the groove and actuating the inner wall of the groove, thus moving the door to the position shown. Figure 2 The door is in the locked position shown. At this time, the door closing toggle block 301 is in the completed state, so that the angled locking tongue is inserted into the jack and the door locking action is completed.

[0079] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
