Detailed Implementation Methods

[0030] See Figures 1 to 6 This invention discloses an integrated automatic door lock device. The door lock device includes a base 1 and a locking body 2 equipped with a locking body torsion spring 20. The top of the base 1 has a lock hole into which a lock head 100 on a door cover can be inserted. The locking body 2 is rotatably installed in the base 1. The door lock device also includes a sealing plate assembly 3, an operating plate 4 equipped with an operating plate torsion spring 40, and a door opening drive device 5. The sealing plate assembly 3 is movably installed in the base 1 and is located directly below the lock hole. The locking body 2 is disposed on one side of the sealing plate assembly 3. The end of the sealing plate assembly 3 facing away from the lock hole is connected to the operating plate 4. The lower part of the base 1... A door opening drive device 5 is provided, which is located at the end of the operating plate 4 facing away from the sealing plate assembly 3. It is used to provide the operating plate 4 with a force opposite to the insertion direction of the lock head 100 to assist in opening the door. When the lock head 100 is inserted into the lock hole, the locking body 2 rotates under the drive of the sealing plate assembly 3. The locking body torsion spring 20 applies a force to the locking body 2 to prevent it from rotating. When the locking body 2 rotates to a certain angle, the lock head 100 continues to be inserted into the lock hole. The locking body torsion spring 20 will apply a reverse force to the locking body 2 to prevent it from resetting until the lock tongue 21 of the locking body 2 presses against the lock head 100, thus completing the door closing and locking.

[0031] Further, see Figure 1 and Figure 7The operating plate 4 is equipped with two operating plate torsion springs 40. Two first mounting slots 41 for mounting the operating plate torsion springs 40 are symmetrically formed on both sides of the operating plate 4. After the door is closed, the operating plate torsion springs 40 apply a force in the closing direction to the operating plate 4 to assist in closing the door. After the door is opened, the operating plate torsion springs 40 apply a force in the opening direction to the operating plate 4 to assist in opening the door. When the lock head 100 is inserted into the lock hole, the operating plate 4 and the sealing plate assembly 3 move downwards synchronously. The operating plate torsion springs 40 apply a force to the operating plate 4 to prevent it from moving downwards. After the operating plate 4 has moved downwards a certain distance, the lock head 100 continues to be inserted into the lock hole. The operating plate torsion springs 40 then apply a reverse force to the operating plate 4 to prevent it from moving upwards and resetting, until the locking tongue 21 of the locking body 2 presses against the lock head 100, completing the door closing and locking process.

[0032] Furthermore, the base 1 is also equipped with a door opening switch connecting plate 6 and a door opening switch 7, which are equipped with a first spring 60; a door locking switch connecting plate 8 and a door locking switch 9, which are equipped with a second spring 80. The door opening switch connecting plate 6 and the door locking switch connecting plate 8 are both located on one side of the movement path of the operating plate 4. When the lock head 100 is inserted into the lock hole, the door locking switch connecting plate 8 moves under the action of the operating plate 4, causing the door locking switch 9 to close. At this time, the door opening switch connecting plate 6 resets under the action of the first spring 60, causing the door opening switch 7 to close. When the lock head 100 is pulled out of the lock hole, the door locking switch connecting plate 8 resets under the action of the second spring 80, causing the door locking switch 9 to open. At this time, the door opening switch connecting plate 6 moves under the action of the operating plate 4, causing the door opening switch 7 to open.

[0033] The system uses the on / off state of the door opening switch 7 to determine whether the door has been fully opened after the door opening drive device 5 automatically opens. A closed state of the door opening switch 7 indicates that the lock head 100 is inserted, while an open state indicates that the door hook is not inserted. The on / off state of the door locking switch 9 determines whether the door is fully closed. A closed state of the door locking switch 9 indicates that the door is fully closed, at which point the system can start, preventing water leakage if the door is not fully closed.

[0034] Further, see Figure 7 and Figure 8 The operation plate 4 is provided with a drive rod 42 on the side facing the door switch connecting plate 6. The top of the drive rod 42 has a first slot inclined surface 421. The door switch connecting plate 6 is provided with a first inclined surface protrusion 61. When the operation plate 4 moves up to reset, the drive rod 42 cooperates with the first inclined surface protrusion 61. Under the action of the drive rod 42, the door switch connecting plate 6 moves, causing the door switch 7 to disconnect.

[0035] Further, see Figure 7 and Figure 9The operation plate 4 is provided with a drive slot 43 on the side facing the door lock switch connecting plate 8. The bottom of the drive slot 43 has a second slot slope 431. The door lock switch connecting plate 8 is provided with a second slope protrusion 81. When the operation plate 4 moves down, the drive slot 43 cooperates with the second slope protrusion 81. Under the action of the drive slot 43, the door lock switch connecting plate 8 moves, so that the door lock switch 9 is closed.

[0036] Further, see Figure 1 The base 1 is provided with a guide mounting seat 11. The end of the sealing plate assembly 3 facing the lock hole has a sealing head 31. The other end of the sealing plate assembly 3 passes through the inner cavity of the guide mounting seat 11 and is connected to the operating plate 4. When the lock head 100 is pulled out from the lock hole, the lock head 100 drives the locking body 2 to reset. The sealing plate assembly 3 and the operating plate 4 are reset under the drive of the locking body 2 until the sealing head 31 abuts against the lock hole.

[0037] Further, see Figure 1 and Figure 6 The sealing head 31 is equipped with a sealing ring 310, the lower end face of the lock hole has a sealing step that cooperates with the sealing ring 310, and the outer periphery of the sealing plate assembly 3 is fitted with a V-shaped sealing ring 32, which is in close contact with the inner cavity of the guide mounting seat 11.

[0038] Further, see Figure 1 The door opening drive device 5 includes a motor and a lead screw equipped with a lead screw nut. The motor drives the lead screw to rotate, thereby controlling the lead screw nut on the moving lead screw to move along the axis of the lead screw.

[0039] Further, see Figure 1 and Figure 6 The locking body 2 has a C-shaped locking hook on the side facing the sealing plate assembly 3. One end of the locking hook has a locking tongue 21 and the other end has a crank 22. When the lock head 100 is inserted into the lock hole, the step of the sealing plate assembly 3 cooperates with the crank 22 of the locking body 2 to drive the locking body 2 to rotate until the locking tongue 21 of the locking body 2 presses against the lock head 100, thus completing the door closing and locking.

[0040] Working principle of this invention:

[0041] 1. Door open

[0042] When the door is open, the sealing ring 310 is installed in the slot of the sealing plate assembly 3. Under the action of the locking body torsion spring 20, the sealing plate of the sealing plate assembly 3 has an upward force, which tightly contacts the sealing ring 310 and the base 1 of the door lock, achieving a waterproof function. The outer surface of the sealing head 31 is flush with the electrical box, with a seamless connection, which can prevent foreign objects and dust from entering.

[0043] 2. Door closing action

[0044] When the door is closed, the lock head 100 moves downward, pressing against the sealing plate. When the step of the sealing plate assembly 3 contacts the crank 22 of the locking body 2, it will drive the locking body 2 to rotate against the torque of the locking body torsion spring 20, and the distance of the locking body torsion spring 20 will decrease. When the locking body 2 rotates to a certain angle, the distance of the locking body torsion spring 20 is compressed to the minimum. When it continues to move, the distance of the locking body torsion spring 20 begins to increase again, and the direction of torque begins to reverse. At this time, the latch 21 acts on the lock head 100, closing the door and providing a downward locking force.

[0045] 3. Manual door opening action

[0046] When the door needs to be opened, the cover door is manually pulled. The sealing plate assembly 3 and the lock head 100 act on the lock tongue 21, forcing the locking body 2 to rotate against the torque of the locking body torsion spring 20. After the locking body 2 rotates, the distance of the locking body torsion spring 20 decreases. When the locking body 2 rotates to a certain angle, the distance of the locking body torsion spring 20 is compressed to the minimum. When it continues to move, the distance of the locking body torsion spring 20 begins to increase again, and the direction of torque begins to reverse, thus opening the door. At this time, the sealing plate assembly 3, under the action of the locking body torsion spring 20, seals the lock hole again.

[0047] 4. Electric door opening action

[0048] When the door needs to be opened, the motor of the door opening drive device 5 starts and pushes upward. The sealing plate assembly 3 and the lock head 100 act on the lock tongue 21, forcing the locking body 2 to rotate against the torque of the locking body torsion spring 20. After the locking body 2 rotates, the distance of the locking body torsion spring 20 decreases. When the locking body 2 rotates to a certain angle, the distance of the locking body torsion spring 20 is compressed to the minimum. When it continues to move, the distance of the locking body torsion spring 20 begins to increase again, and the direction of torque begins to reverse. Under the action of the door opening drive device 5 and the locking body torsion spring 20, the door is opened. At this time, the sealing plate assembly 3 seals the lock hole again under the action of the locking body torsion spring 20.

[0049] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
