Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a half-close door device and a door lock. Background Art

[0002] A door lock is a device used to protect property, premises or information security. The role of a lock is to provide a means of limiting and controlling access, ensuring that only legitimate people or authorized individuals can use or enter the protected area or items. Locks can be used in a variety of applications, such as home door locks, office door locks, vehicle locks, safe locks, computer password locks, etc.

[0003] Door locks in the prior art generally require manual closing of the door to be locked. There is a situation where someone leaves but the door is not closed, or a child at home accidentally touches the door but does not have enough strength to completely close the door, causing the door to be in a half-open state, posing a safety hazard. Utility Model Content

[0004] In view of this, the utility model provides a half-closed door closing device and a door lock to solve the potential safety hazards caused by the door being in a half-closed state.

[0005] In a first aspect, the utility model provides a half-closed door closing device, comprising:

[0006] A power mechanism is arranged on the door lock, and a power output end passes through the lock body of the door lock;

[0007] A transmission member connected to the power mechanism outside the lock body;

[0008] The limiting structure is arranged on the door frame and corresponds to the position of the power mechanism. The limiting structure includes an avoidance opening and a contact surface which are arranged in sequence. The contact surface is arranged away from the opening direction of the door body. The power mechanism can drive the transmission member to pass through the avoidance opening and contact the contact surface so that the door lock moves closer to the door frame.

[0009] Beneficial effects:

[0010] When the door body is in a half-closed state, the power mechanism of the half-closed door closing device of the utility model can drive the transmission member to pass through the avoidance opening and abut against the abutting surface. After the transmission member abuts against the abutting surface, the free end of the transmission member cannot move, so that the connection end of the transmission member and the power mechanism is subjected to a reaction force, and the door body is moved close to the door frame to achieve the door closing. Therefore, when a person leaves but the door is not closed, or a child at home accidentally touches the door but is not strong enough to completely close the door, the half-closed door closing device can automatically close the door, avoiding the safety hazards caused by the door being in a half-closed state.

[0011] In an optional embodiment, the power mechanism can drive the transmission member to rotate around a first rotating shaft, the first rotating shaft is perpendicular to the door strike plate of the door lock, and the limiting structure includes a limiting groove formed on the door frame, the notch of the limiting groove forms an avoidance opening, an abutment protrusion is formed below the avoidance opening, and a side wall of the abutment protrusion forms an abutment surface.

[0012] Beneficial effects:

[0013] Through such an arrangement, the transmission member can first move towards the door frame under the drive of the power mechanism, and pass through the avoidance opening into the limit groove. Then, after the rotation angle of the transmission member exceeds 90 degrees, the free end of the transmission member generates a component force in the direction of opening the door, and can apply a force in the direction of opening the door body toward the abutment surface after abutting against the abutment surface, so that the door body is subjected to a reaction force to achieve door closing.

[0014] In an optional embodiment, the transmission member includes:

[0015] A transmission rod connected to a power output end of the power mechanism;

[0016] The limiting convex portion is formed on the transmission rod and is located on a side of the transmission rod away from the power mechanism, and can abut against the abutting surface.

[0017] Beneficial effects:

[0018] The power mechanism can drive the transmission rod to rotate along the first axis to carry the limiting protrusion through the avoidance opening and abut against the abutment surface, and use the limiting protrusion to apply a force toward the opening direction of the door body to the abutment surface.

[0019] In an optional embodiment, the limiting groove includes a first groove section and a second groove section connected in sequence, the first groove section is connected to the avoidance opening, and the width in the vertical direction is greater than or equal to the length of the transmission member, the second groove section is connected to the bottom of the first groove section, and the abutment surface is located on one side of the second groove section.

[0020] Beneficial effects:

[0021] By such arrangement, when the user closes the door normally, no matter what angle the transmission member is at, the transmission member can smoothly enter the first slot section, and will not abut against the slot wall of the limiting slot to hinder the door closing.

[0022] In an optional embodiment, the half-closed door device is characterized by further comprising:

[0023] The slide rail is arranged in the door lock and extends in a vertical direction. The power mechanism is arranged on the slide rail and can slide along the slide rail.

[0024] Beneficial effects:

[0025] The slide rail can allow the power mechanism to slide along the slide rail when the power mechanism is about to be overloaded, so as to increase the distance between the power mechanism and the door frame and avoid overload caused by the reduction of the distance.

[0026] In an optional embodiment, the half-closed door device is characterized by further comprising:

[0027] The return spring is supported between the power mechanism and the door lock. When the power mechanism drives the transmission member to abut against the abutting surface, the power mechanism compresses the return spring.

[0028] Beneficial effects:

[0029] With such an arrangement, when the door is closed, the power mechanism can compress the return spring and move to the upper end of the slide rail, and then the power mechanism continues to rotate, driving the transmission member to return to its original position, and the return spring can drive the power mechanism back to its initial position through its own elastic restoring force.

[0030] In an optional embodiment, the abutment surface is located below the avoidance opening, an abutment portion is protrudingly formed on the top of the slide rail, one end of the return spring is fixedly connected to the abutment portion, and the other end is fixedly connected to the power mechanism.

[0031] In an optional embodiment, the half-closed door device is characterized by further comprising:

[0032] A strip-shaped hole is formed on the lock plate of the door lock and extends in a vertical direction, and a power output end of the power mechanism passes through the strip-shaped hole.

[0033] Beneficial effects:

[0034] When the power mechanism moves along the slide rail, the power output end of the power mechanism can move along the length direction of the strip hole to avoid interference between the locking plate and the power output end of the power mechanism.

[0035] In an optional embodiment, the half-door closing device is characterized in that it also includes a detection device, which is arranged on the door strike plate of the door lock and can detect the relative position of the door lock and the door frame.

[0036] Beneficial effects:

[0037] When the door lock detects that the door is not closed, the control device turns on the low-power lens in the lock body. After software recognition, it can determine whether the door is in a half-open state based on the relative position of the door and the door frame. This overcomes the problem of being unable to distinguish whether the door is closed and hear the door lock's open door reminder when the door is in a half-open state and the background sound is noisy or the distance is far.

[0038] In a second aspect, the utility model further provides a door lock, characterized in that it includes the half-closed door device of the first aspect of the utility model.

[0039] Beneficial effect: The door lock of the second aspect of the utility model includes or uses the half-closed door closing device of the first aspect of the utility model, and thus has its beneficial effect, that is, when the door body is in a half-closed state, the power mechanism can drive the transmission member to pass through the avoidance opening and abut against the abutment surface. After the transmission member abuts against the abutment surface, the free end of the transmission member cannot move, so that the connection end of the transmission member and the power mechanism is subjected to a reaction force, and the door body is carried to move closer to the door frame to achieve door closing. Therefore, when a person leaves but the door is not closed, or when a child at home accidentally touches the door but does not have enough strength to completely close the door, the half-closed door closing device can achieve automatic door closing, avoiding the safety hazard caused by the door being in a half-closed state.

[0050] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0051] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0052] According to an embodiment of the utility model, on the one hand, a half-closed door device is provided, comprising a power mechanism 1, a transmission member 2 and a limiting structure 3. The power mechanism 1 is arranged on the door lock 7, and the power output end passes through the lock body of the door lock 7. The transmission member 2 is connected to the power mechanism 1 outside the lock body. The limiting structure 3 is arranged on the door frame 8 and corresponds to the position of the power mechanism 1. The limiting structure 3 includes an avoidance opening 301 and an abutment surface 302 sequentially arranged along the movement direction of the transmission member 2. The abutment surface 302 and the avoidance opening 301 are located on the same side of the limiting structure 3. The power mechanism 1 can drive the transmission member 2 to pass through the avoidance opening 301 and abut against the abutment surface 302, so that the door lock 7 moves close to the door frame 8.

[0053] like Figure 2 and Figure 3 As shown, when the door body 9 is in a half-closed state, the power mechanism 1 can drive the transmission member 2 to pass through the avoidance opening 301 and abut against the abutment surface 302. After the transmission member 2 abuts against the abutment surface 302, the free end of the transmission member 2 cannot move, so that the connection end of the transmission member 2 and the power mechanism 1 is subjected to a reaction force, and the door body 9 is moved close to the door frame 8 to achieve the door closing. Therefore, when a person leaves but the door is not closed, or a child at home accidentally touches the door but is not strong enough to completely close the door, the half-closed door closing device can automatically close the door, avoiding the safety hazards caused by the door being in a half-closed state.

[0054] In one embodiment, the power mechanism 1 can drive the transmission member 2 to rotate around a first rotating shaft, the first rotating shaft is perpendicular to the door strike plate of the door lock 7, the limiting structure 3 includes a limiting groove formed on the door frame 8, the groove of the limiting groove forms an avoidance opening 301, and an abutment protrusion is formed below the avoidance opening 301, and a side wall of the abutment protrusion forms an abutment surface 302.

[0055] By setting it up like this, Figure 2 As shown, the transmission member 2 can first move towards the door frame 8 under the drive of the power mechanism 1, and pass through the avoidance opening 301 into the limit groove, and then, as shown in FIG. Figure 3 As shown, after the rotation angle of the transmission member 2 exceeds 90 degrees, the free end of the transmission member 2 generates a component force toward the door opening direction, and can apply a force toward the abutment surface 302 toward the door body 9 opening direction after abutting against the abutment surface 302, so that the door body 9 is subjected to a reaction force to achieve door closing (see Figure 4 and Figure 5 ).

[0056] Preferably, the limiting structure 3 is preferably formed on the side strip of the door frame 8. The avoidance opening 301 is arranged at a side edge of the door frame 8 facing the opening direction of the door body 9, so that the transmission rod 201 passes through the avoidance opening 301 and enters the limiting groove. The rotation source can be selected as a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0057] As a convertible embodiment, the avoidance opening 301 is formed on the inner peripheral wall of the door frame 8, and the transmission member 2 is a pull rod, on which a contact convex portion that can contact with the contact surface 302 is formed. The power mechanism 1 can first drive the pull rod to move toward the door frame 8, and in the initial state, the contact convex portion extends in a direction away from the limiting structure 3 to avoid interference between the contact convex portion and the limiting structure 3. After the pull rod moves into place, the power mechanism 1 can drive the pull rod to rotate so that the contact convex portion enters the avoidance opening 301 and contacts with the contact surface 302, and then the power mechanism 1 retracts the pull rod to close the door.

[0058] In one embodiment, the transmission member 2 includes a transmission rod 201 and a limiting protrusion 202. The transmission rod 201 is connected to the power output end of the power mechanism 1. The limiting protrusion 202 is formed on the transmission rod 201 and is located on a side of the transmission rod 201 away from the power mechanism 1, and can abut against the abutment surface 302.

[0059] The power mechanism 1 can drive the transmission rod 201 to rotate along the first axis to carry the limiting protrusion 202 through the avoidance opening 301 and abut against the abutment surface 302, and use the limiting protrusion 202 to apply a force to the abutment surface 302 in the opening direction of the door body 9.

[0060] In one embodiment, Figure 6As shown, the limiting groove includes a first groove section 303 and a second groove section 304 connected in sequence, the first groove section 303 is connected to the avoidance opening 301, and the width in the vertical direction is greater than or equal to the length of the transmission member 2, the second groove section 304 is connected to the bottom of the first groove section 303, and the abutment surface 302 is located on one side of the second groove section 304.

[0061] By setting it up like this, Figure 7 As shown, when the user closes the door normally, no matter what angle the transmission member 2 is at, the transmission member 2 can smoothly enter the first slot section 303 and will not abut against the slot wall of the limiting slot to hinder the closing of the door.

[0062] In one embodiment, the half-closed door device further comprises a slide rail 4. The slide rail 4 is arranged in the door lock 7 and extends in a vertical direction. The power mechanism 1 is arranged on the slide rail 4 and can slide along the slide rail 4.

[0063] During the process of the half-closed door device closing the door, the distance between the door body 9 and the door frame 8 decreases, but the length of the transmission member 2 itself remains unchanged. If the position of the power mechanism 1 remains unchanged, the power mechanism 1 may not be able to continue to rotate, causing overload.

[0064] The slide rail 4 can allow the power mechanism 1 to slide along the slide rail 4 when the power mechanism 1 is about to be overloaded, so as to increase the distance between the power mechanism 1 and the door frame 8 and avoid overload caused by the reduction of the distance.

[0065] As a convertible embodiment, the transmission member 2 is a telescopic rod, and an elastic reset member is arranged inside the telescopic rod. When the distance between the door body 9 and the door frame 8 decreases, the telescopic rod can be compressed to allow the power mechanism 1 to continue to rotate. The elastic reset member is preferably, but not limited to, a reset spring 5.

[0066] In one embodiment, the half-closed door device further comprises a return spring 5. The return spring 5 is supported between the power mechanism 1 and the door lock 7. When the power mechanism 1 drives the transmission member 2 to abut against the abutting surface 302, the power mechanism 1 compresses the return spring 5.

[0067] With such an arrangement, when the door is closed, the power mechanism 1 can compress the return spring 5 and move to the upper end of the slide rail 4. Then the power mechanism 1 continues to rotate, driving the transmission member 2 to return. The return spring 5 can drive the power mechanism 1 back to the initial position through its own elastic restoring force.

[0068] In one embodiment, the abutment surface 302 is located below the avoidance opening 301 , and an abutment portion 401 is protrudingly formed on the top of the slide rail 4 . One end of the return spring 5 is fixedly connected to the abutment portion 401 , and the other end is fixedly connected to the power mechanism 1 .

[0069] As a convertible embodiment, an abutment portion 401 is formed in the housing of the door lock 7 , one end of the return spring 5 is fixedly connected to the abutment portion 401 , and the other end is fixedly connected to the power mechanism 1 .

[0070] In one embodiment, the half-closed door device further comprises a strip hole. The strip hole is formed on the strike plate of the door lock 7 and extends in the vertical direction, and the power output end of the power mechanism 1 passes through the strip hole. When the power mechanism 1 moves along the slide rail 4, the power output end of the power mechanism 1 can move along the length direction of the strip hole to avoid interference between the strike plate and the power output end of the power mechanism 1.

[0071] In one embodiment, the half-closed door device further comprises a detection device 6. The detection device 6 is arranged on the door strike plate of the door lock 7 and can detect the relative position between the door lock 7 and the door frame 8.

[0072] Preferably, the door lock 7 also includes a control device, which is communicatively connected with the detection device 6 and the power mechanism 1. When the door lock 7 detects that the door is not closed, the control device turns on the low-power lens in the lock body. After software recognition, it can determine whether the door body 9 is in a half-closed state based on the relative position of the door and the door frame 8, thereby overcoming the problem of being unable to distinguish whether the door is closed and hearing the door lock 7's prompt that the door is not closed when the door is in a half-closed state and the background sound is noisy or the distance is far.

[0073] When the software detects that the relative position of the door and the door frame 8 is in a half-open state, the power mechanism 1 is controlled to drive the transmission member 2 to rotate. When the transmission member 2 rotates to a certain angle, the limiting protrusion 202 of the transmission member 2 abuts against the abutment surface 302 of the limiting mechanism. At this time, the transmission member 2 continues to rotate and drives the door body 9 to move in the direction of closing the door until the door body 9 is completely closed.

[0074] After the door body 9 is completely closed, the power mechanism 1 compresses the elastic reset member and moves it to the upper end of the slide rail 4. The power mechanism 1 continues to rotate, driving the transmission member 2 to rotate and reset. The reset spring 5 loses the external force and drives the power mechanism 1 to the initial position through its own elastic restoring force.

[0075] The control module may include a programmable logic control component (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well known to those skilled in the art and will not be described in detail here. The communication connection may be selected through a signal connection or through a wire or cable connection.

[0076] The detection device 6 can be selected as a wide-angle low-power lens, or an infrared beam sensor, a Hall sensor, a radar ranging module or a micro switch, etc., or the detection device 6 can also be selected as an original functional component on the door lock 7, such as a cat's eye lens and a radar component.

[0077] According to an embodiment of the present utility model, on the other hand, a door lock 7 is provided, comprising the half-closed door device provided in the first aspect of the present utility model.

[0078] The door lock 7 of the second aspect of the utility model includes or uses the half-closed door closing device of the first aspect of the utility model, and thus has its beneficial effect, that is, when the door body 9 is in a half-closed state, the power mechanism 1 can drive the transmission member 2 to pass through the avoidance opening 301 and abut against the abutment surface 302. After the transmission member 2 abuts against the abutment surface 302, the free end of the transmission member 2 cannot move, so that the connection end of the transmission member 2 and the power mechanism 1 is subjected to a reaction force, and the door body 9 is carried to move closer to the door frame 8 to achieve door closing. Therefore, when a person leaves but the door is not closed, or a child at home accidentally touches the door but is not strong enough to completely close the door, the half-closed door closing device can achieve automatic door closing, avoiding the safety hazard caused by the door being in a half-closed state.

[0079] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
