Description

Technical Field

[0001] The present invention belongs to the technical field of doors, intelligent doors and building materials, and in particular relates to an intelligent door structure. Background Art

[0002] Doors are a common structure in everyday life, and they come in many different types, including the entrance door. The entrance door is the first door into a house (indoors), also known as the entry door. There are many different types of entrance doors. A typical entrance door needs to be closed immediately after someone leaves the house (for example, the main door of an apartment or home, which requires closing for safety reasons). However, there are also some scenarios where the entrance door doesn't need to be closed immediately. For example, a first-floor house with an enclosed courtyard has an entrance door leading to the courtyard. This door doesn't necessarily need to be closed immediately because it's blocked by the courtyard wall. Even if the door is open, the entire house appears "closed" to the outside world. People inside may even frequently open the door to ensure proper ventilation. However, if it starts to rain while the door is open, rainwater will inevitably continue to enter the house on the wind.

DETAILED DESCRIPTION

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

[0038] like Figures 1 to 12 As shown,

[0039] An intelligent door structure includes a door lock, an outer door frame 2 fixed to a wall 1, and an inner door panel 3 hinged to the outer door frame. When the inner door panel is in a closed position, the inner door panel is located inside the outer door frame.

[0040] It also includes a rainwater pipe 4, a pressure gas tank and an air pump for supplying air to the pressure gas tank;

[0041] The inner door panel is provided with a plate gear 31, and a wall cavity groove is provided on the wall. The wall cavity groove is provided with a compound door gear 11 meshing with the plate gear, a position-avoiding gear 12 meshing with the compound door gear, a compound door ratchet gear 13 coaxially fixed with the position-avoiding gear, a compound door ratchet bar 14 adapted to the compound door ratchet gear, and a compound door cylinder 15 for driving the compound door ratchet bar. The pressure gas tank supplies air to the compound door cylinder through a compound door air pipe 51. The compound door air pipe is provided with a compound door rain-bearing valve 52 and a compound door push valve 53. The compound door cylinder is provided with a deflation reset hole 15a.

[0042] The rainwater pipe includes a vertical upper rain pipe 41, a horizontal middle rain pipe 42 and a vertical lower supporting pipe 43. The lower end of the vertical upper rain pipe is connected with one end of the horizontal middle rain pipe. The bottom of the horizontal middle rain pipe is provided with a pipe bottom hole 42a connected with the upper end of the vertical lower supporting pipe. The vertical lower supporting pipe is provided with a rain-bearing block 431 that is slidably sealed with the vertical lower supporting pipe. The double door rain-bearing valve includes a rain-bearing valve body and a rain-bearing valve rod 521 connected to the rain-bearing block. The double door push valve includes a push valve body, a push valve rod 531 pushed by the inner door panel and a push spring for driving the push valve rod to reset. When the inner door panel is in the closed position: the double door push valve is in a closed state.

[0043] The avoidance gear is connected to the compound door ratchet gear via a gear shaft 311 , and the rotation centerline of the gear on the plate coincides with the rotation centerline of the inner door plate.

[0044] The rainwater pipe is installed outdoors. Under normal circumstances, the door can be opened and closed normally. During rain, rainwater entering the vertical rainwater pipe is discharged through the horizontal middle rainwater pipe. As rainwater flows through the horizontal middle rainwater pipe, it presses down on the rainwater receiving block, which in turn drives the rainwater receiving valve stem, opening the double-door rainwater receiving valve. When the inner door panel is not closed, the double-door push valve remains open. Therefore, when it rains and the inner door panel is not closed, the double door rain receiving valve and the double door push valve arranged on the double door air pipe are both in the open state. At this time, a part of the high-pressure gas in the pressure gas tank will enter the double door cylinder through the double door air pipe. The double door cylinder works, driving the double door ratchet bar to move (before the inner door panel reaches the closed position, when the high-pressure gas enters the double door cylinder through the double door air pipe, a small amount of gas will be discharged from the air deflation reset hole, but because the exhaust speed is much smaller than the intake speed, it does not affect the normal operation of the double door cylinder). The double door ratchet bar drives the gear on the double door ratchet gear, the avoidance gear, and the double door gear drive plate to rotate, so that the inner door panel also rotates until the inner door panel reaches the closed position, thus completing the process of automatically closing the door to avoid rain.

[0045] When the inner door panel reaches the closed position, the compound door push valve is in the closed state. At this time, the pressure gas tank no longer supplies air to the compound door cylinder. Under the action of the pushing spring, the compound door valve stem and the compound door ratchet bar are reset. During the reset process of the compound door ratchet bar, the compound door ratchet bar will not drive the compound door ratchet gear (when the compound door valve stem is extended, the compound door ratchet bar can drive the compound door ratchet gear to rotate. When the compound door valve stem is reset, the compound door ratchet bar does not drive the compound door ratchet gear to rotate).

[0046] The rain-receiving valve body includes a rain-receiving vertical valve pipe 522, a rain-receiving inner piston 523 that is slidably sealed with the rain-receiving vertical valve pipe, a rain-receiving upper porous plate 524 provided at the upper end of the rain-receiving vertical valve pipe, a rain-receiving lower porous plate 525 provided at the lower end of the rain-receiving vertical valve pipe, and a rain-receiving spring 526 provided below the rain-receiving inner piston. The rain-receiving vertical valve pipe is provided with a rain-receiving valve inlet 522a connected to the compound door air pipe and a rain-receiving valve outlet 522b connected to the compound door air pipe. A rain-receiving valve hole 523a is provided. The upper end of the rain-receiving spring is connected to the rain-receiving inner piston, and the lower end of the rain-receiving spring is connected to the rain-receiving lower porous plate. The rain-receiving valve stem passes through the upper rain-receiving porous plate. The upper end of the rain-receiving valve stem is connected to the rain-receiving block, and the lower end of the rain-receiving valve stem is connected to the rain-receiving inner piston. A rain-receiving upper limiter 527 is provided on the upper rain-receiving porous plate, and a rain-receiving lower limiter 528 is provided on the lower rain-receiving porous plate. A soft membrane 421 is provided in the bottom hole of the pipe to seal the bottom hole of the pipe, and the soft membrane is fixed to the top of the rain-receiving block.

[0047] When the inner piston of the rain-receiving valve contacts the upper limit body of the rain-receiving valve: the compound door rain-receiving valve is in the closed state, the inlet of the rain-receiving valve is sealed by the inner piston of the rain-receiving valve, and the outlet of the rain-receiving valve is sealed by the inner piston of the rain-receiving valve;

[0048] When the inner piston of the rain receiving valve contacts the lower limit body of the rain receiving valve, the compound door rain receiving valve is in the open state, and the rain receiving valve inlet, the rain receiving valve hole and the rain receiving valve outlet are connected in sequence.

[0049] In this solution, normally, the inner rain-receiving piston contacts the upper limiter, and the double-door rain-receiving valve is closed. When rainwater flows through the horizontal rain pipe, it presses down on the perforated soft membrane, causing the rain-receiving block to move downward. This pushes the rain-receiving valve stem and the inner rain-receiving piston downward until the inner rain-receiving piston contacts the lower limiter, at which point the double-door rain-receiving valve is open. After the rain stops and the horizontal rain pipe drains, the rain-receiving spring resets the inner rain-receiving piston, the rain-receiving valve stem, and other components.

[0050] The pushing valve body includes a pushing transverse valve tube 532, a pushing inner piston 533 that is slidingly sealed with the pushing transverse valve tube, a pushing front porous plate 534 provided at one end of the pushing transverse valve tube, a pushing rear porous plate 535 provided at the other end of the pushing transverse valve tube, and a pushing spring provided in the pushing transverse valve tube. The pushing transverse valve tube is provided with a pushing valve inlet 532a connected to the compound door air pipe and a pushing valve outlet 532b connected to the compound door air pipe. A pushing valve hole 533a is provided on the pushing inner piston. One end of the pushing spring is connected to the pushing inner piston, and the other end of the pushing spring is connected to the pushing rear porous plate. The pushing valve stem passes through the pushing front porous plate. One end of the pushing valve stem is provided with a pushing block 54 for being pushed by the side wall of the inner door plate. The other end of the pushing valve stem is connected to the pushing inner piston. A pushing front limiting body 537 is provided on the pushing front porous plate, and a pushing rear limiting body 538 is provided on the pushing rear porous plate.

[0051] The outer door frame is provided with a door frame hole for the pushing block to pass through, and the door frame hole is communicated with the wall cavity groove;

[0052] When the pushing inner piston contacts the pushing front limiter: the compound door pushing valve is in the open state, and the pushing valve inlet, the pushing valve hole and the pushing valve outlet are connected in sequence;

[0053] When the pushing inner piston contacts the pushing rear limiter: the compound door pushing valve is in a closed state, the pushing valve inlet is sealed by the pushing inner piston, and the pushing valve outlet is sealed by the pushing inner piston;

[0054] When the inner door panel is in the closed position: the inner piston is pushed to contact the rear limiting body.

[0055] In this solution, when the inner door panel is in the open position, the compound door push valve is in the open state. During the inner door panel's closing process, at a certain moment, the inner door panel pushes the push block, which drives the push valve stem and the push inner piston to move together until the push inner piston contacts the push rear limiter. At this point, the inner door panel is in the closed position, and the compound door push valve is in the closed state.

[0056] The described compound valve cylinder includes a compound valve cylinder body 151, a compound valve inner piston 152 which is slidingly sealed with the compound valve cylinder body, and a compound valve piston rod 153 provided on the compound valve inner piston. The compound valve inner piston divides the interior of the compound valve cylinder body into a compound valve air chamber 151a and a compound valve cavity 151b which is connected to the atmosphere. The compound valve piston rod passes through the compound valve cavity and is connected to the compound valve ratchet bar. A compound valve spring 154 which is sleeved on the compound valve piston rod is provided in the compound valve cavity. One end of the compound valve spring is connected to the compound valve inner piston, and the other end of the compound valve spring is connected to the compound valve cylinder body. A deflation reset hole is provided on the compound valve cylinder body, and the deflation reset hole is connected to the compound valve air chamber. The pressure gas tank is connected to the compound valve air chamber through the compound valve air pipe.

[0057] When both the double-door rain-bearing valve and the double-door push valve are in the open state, a portion of the high-pressure gas in the pressure gas tank will enter the double-door air cavity through the double-door air pipe, and the double-door inner piston, double-door piston rod, and double-door ratchet bar will move together. The double-door ratchet bar will rotate through the double-door ratchet gear, the avoidance gear, and the gear on the double-door gear drive plate, so that the inner door panel will also rotate until the inner door panel reaches the closed position. In the above process, before the inner door panel reaches the closed position, when a portion of the high-pressure gas in the pressure gas tank enters the double-door air cavity through the double-door air pipe, a small amount of gas will be discharged from the air release reset hole, but the exhaust speed is much lower than the intake speed, so it does not affect the normal operation of the double-door cylinder. When the inner door panel reaches the closed position, the double-door push valve is in the closed state. At this time, the pressure gas tank no longer supplies air to the double-door air cavity. Under the action of the push spring, the double-door inner piston, double-door piston rod, and double-door ratchet bar move together to reset.

[0058] The door lock includes a lock rotating part provided on the inner door panel, a lock tongue provided on the lock rotating part and a lock slot provided on the outer door frame. The lock slot is adapted to the lock tongue. A door panel inner cavity is provided in the inner door panel. The lock rotating part is located in the door panel inner cavity. A cam 32 connected to the lock rotating part and an elastic air bag 33 squeezed by the cam are provided in the door panel inner cavity. The rotation center line of the cam coincides with the rotation center line of the lock rotating part. A pre-opening valve 55 is provided on the air pipe of the compound door. The pre-opening valve includes a pre-opening vertical valve 55 closed at both ends. The valve tube 551 and the pre-start inner piston 552 that cooperates with the pre-start vertical valve tube in a sliding and sealing manner. The pre-start inner piston divides the interior of the pre-start vertical valve tube into a pre-start upper chamber 55a and a pre-start lower chamber 55b. The pre-start vertical valve tube is provided with a pre-start inlet 551a connected to the compound valve air pipe and a pre-start outlet 551b connected to the compound valve air pipe.

The pre-start upper chamber is provided with a pre-start upper limit body 553, and the pre-start lower chamber is provided with a pre-start lower limit body 554.

[0059] When the inner piston of the pre-start valve contacts the pre-start lower limit body: the pre-start valve is in the open state, and the pre-start inlet, pre-start hole and pre-start outlet are connected in sequence;

[0060] When the inner piston of the lip valve contacts the upper limit body of the lip valve, the lip valve is in the closed state, the lip valve inlet is sealed by the inner piston of the lip valve, and the lip valve outlet is sealed by the inner piston of the lip valve;

[0062] When the door lock is in the unlocked state, the cam squeezes the elastic airbag before the door is opened. When the door lock is in the locked state, the cam separates from the elastic airbag before the door is opened.

[0063] Normally, the door lock is in the closed position, and the pre-opening valve is in the open position. When it rains and the inner door panel automatically closes, if the user wishes to open the door, they can turn the door lock, unlock it, and then open the door. When the door lock is turned, the lock's rotating portion drives the cam to rotate, squeezing the pre-opening elastic airbag. A portion of the gas in the pre-opening elastic airbag enters the pre-opening lower chamber through the pre-opening thick hose, causing the pre-opening inner piston to rise (simultaneously, the slow-down orifice is also exhausting, but the intake speed is significantly faster than the exhaust speed, so it does not affect the rise of the pre-opening inner piston). The pre-opening valve then reaches a closed position (the pre-opening valve is located on the double-door air pipe, so the double-door air pipe is disconnected) and remains closed for a period of time (the slow-down orifice slowly exhausts gas, and the pre-opening inner piston slowly descends and resets). During this period, the user can leave the outer door frame area (enter or exit). If it continues to rain during this process, the present invention will not automatically close the door (to prevent it from affecting the user's entry or exit). Then, when the piston in the lock is lowered and reset, the air pipe of the reclosing door is open again. If it is still raining at this time, the present invention will automatically close the door to avoid the rain (the user has completed entering or leaving the door). In addition, when the door lock is reset, the cam leaves the elastic airbag of the lock, and the elastic airbag of the lock is inflated again, and the outside air enters the elastic airbag of the lock through the replenishment one-way valve.

[0064] A ground pump groove is provided on the ground, and the air pump is in the ground pump groove. The air pump includes a pump pressure plate 61, a pump elastic airbag 62, a pump base 63, a pump limit seat 64, a pump vertical slide 65 and a pump spring 66 arranged on the pump vertical slide. An elastic membrane 67 is provided on the pump groove to seal the pump groove notch. The bottom of the elastic membrane is fixed to the top of the pump pressure plate, the bottom of the pump pressure plate is fixed to the upper end of the pump vertical slide, the pump vertical slide is slidably connected to the pump base, the pump base is fixed to the bottom of the ground pump groove, the pump limit seat is fixed to the pump base, the pump pressure plate, pump limit seat and pump base are arranged in sequence from top to bottom, the upper end of the pump spring is connected to the pump pressure plate, the lower end of the pump spring is connected to the pump base, the pump elastic airbag is between the pump pressure plate and the pump base, the pump elastic airbag is fixed to the pump pressure plate, the pump elastic airbag is fixed to the pump base, an air inlet one-way valve is provided on the pump elastic airbag, the pump elastic airbag is connected to the pressure gas tank through the pump air supply pipe, and the pump air supply pipe is provided with an air supply one-way valve. The direction of the air intake one-way valve is from the outside through the air intake one-way valve to the inside of the pump elastic airbag, and the direction of the air supply one-way valve is from the inside of the pump elastic airbag through the air supply one-way valve to the pressure gas tank.

[0065] In this solution, the floor pump trough is located in the path people must pass through when entering or leaving the house (near the outer door frame). When people enter or leave the house, they pass by and step on the elastic membrane, causing the pump pressure plate and pump vertical slide bar to move downward together, squeezing the pump elastic airbag. Some of the gas inside the pump elastic airbag enters the pressure tank through the pump air supply pipe, thereby inflating the pressure tank. After the person's foot leaves the elastic membrane, the pump elastic airbag inflates again due to the restoring force of the pump spring and the elasticity of the pump elastic airbag itself. During this process, outside air enters the pump elastic airbag through the air inlet check valve.
