[0048] The technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] A kick-open door structure includes: a door frame 1, a movable door 2, and a kick assembly 3;

[0050] The movable door 2 is movably installed on the door frame 1, and the movable door 2 is provided with a connecting mother part 21; the kick assembly 3 includes: a main kick component 31, a locking rocker plate 32, a central support column 37, and a reset elastic component 33;

[0051] The main kick member 31 can be pressed and installed on the door frame 1; the middle support column 37 is installed between the two ends of the snap-fit ​​rocker 32, and the middle support column 37 can be connected to the door frame 1 in a limited swing manner, so that the snap-fit ​​rocker 32 swings to lift one end.

[0052] The first end of the snap-fit ​​rocker 32 is provided with a male connector 311; the reset elastic member 33 presses the male connector 311 against the female connector 21, so that the male connector 311 and the female connector 21 are detachably connected, and the movable door 2 is limited to the door frame 1; the main kick member 31 moves to abut against the second end of the snap-fit ​​rocker 32, and is used to drive the second end of the snap-fit ​​rocker 32 to move, causing the first end of the snap-fit ​​rocker 32 to swing so that the male connector 311 is disengaged from the female connector 21.

[0053] This solution provides a foot-kick door opening structure. Users can kick the main kick member 31 at the bottom to drive the connecting male part 311 of the locking rocker 32 to separate from the connecting female part 21 of the movable door 2, thereby achieving the effect of foot-kick door opening. This effectively solves the problem that existing door structures require the use of handles to open and close the door, and improves the comfort of opening the door.

[0054] Specifically, the movable door 2 is movably installed on the door frame 1. In the initial state, the male part 311 of the first end of the locking rocker 32 is pressed tight under the elastic force of the reset elastic member 33, so that the male part 311 is connected to the female part 21, and the movable door 2 is limited to the door frame 1. Thus, the movable door 2 inside the door frame 1 is locked and fixed, and the movable door 2 cannot move. When it is necessary to drive the movable door 2 to move, the user can press the main kick member 31 with his foot. The main kick member 31 drives the locking rocker 32 to swing around the central support 37 as the fulcrum. The more the second end of the locking rocker 32 is pressed down, the male part 311 of the first end of the locking rocker 32 will gradually disengage from the female part 21, thereby allowing the movable door 2 to move. No longer limited to the door frame 1, the user can open and close the movable door 2 normally; and during the swinging process of the locking rocker 32, the connecting male part 311 of the first end of the locking rocker 32 is pressed by the reset elastic member 33. One end of the reset elastic member 33 contacts the locking rocker 32, and the other end of the reset elastic member 33 can be fixed to the wall surface of the door frame 1 or other supporting surface. During the process of the connecting male part 311 of the first end of the locking rocker 32 disengaging from the connecting female part 21, the reset elastic member 33 is compressed. When the user no longer presses the main kick piece 31, the reset elastic member 33 drives the first end of the locking rocker 32 to reset, thereby driving the second end of the locking rocker 32 to reset, so as to drive the main kick piece 31 to reset to the unpressed state. In some embodiments, since the first end of the locking rocker 32 is pressed by the reset elastic member 33, when the movable door 2 needs to be closed, the movement of the movable door 2 can drive the first end of the locking rocker 32 to adjust its position. When the connecting female part 21 of the movable door 2 passes the connecting male part 311, the reset elastic member 33 presses the connecting male part 311 against the connecting female part 21, thereby limiting the movable door 2 to the door frame 1. For example, when the connecting female part 21 is an opening and the connecting male part 311 is a locking plate, the locking plate is pressed against the opening by the reset elastic member 33.

[0055] Among them, the reset elastic element 33 is a known mechanism with elastic deformation, such as a gas spring, spring, elastic band, etc.

[0056] The male connector 311 and the female connector 21 are connected using a known connection method. For example, in one embodiment, the male connector 311 and the female connector 21 are connected by magnetic attraction; in another embodiment, the male connector 311 is attracted to the female connector 21 under negative pressure. In this solution, preferably, as shown... Figure 2 The female connector 21 is provided with a connector slot; the male connector 311 is provided with a connector hook; the connector hook engages with the connector slot.

[0057] Preferably, the kick assembly 3 includes: a secondary kick component 34, a fixing post 35, and a torsion spring 36;

[0058] The secondary kick member 34 can be pressed and installed on the door frame 1. The main kick member 31 and the secondary kick member 34 are distributed facing each other on the front and rear sides of the door frame 1. The fixing post 35 is installed on the door frame 1 and is located between the main kick member 31 and the secondary kick member 34. The middle part of the torsion spring 36 is sleeved on the fixing post 35. One torsion bar 361 of the torsion spring 36 is connected to the second end of the locking rocker plate 32 on one side, and the other torsion bar 361 is connected to the secondary kick member 34 on the other side.

[0059] The main kick arm 31 is located on one side of the door frame 1, and the secondary kick arm 34 is located on the other side of the door frame 1, corresponding to the front and rear of the movable door 2, respectively. In this design, the main kick arm 31 is positioned in front of the movable door 2, and the secondary kick arm 34 is positioned behind the movable door 2. When the door needs to be opened, the main kick arm 31 can be pressed, and the movable door 2 can be opened or closed normally. When the user is inside, the door can also be opened by pressing the secondary kick arm 34 behind the movable door 2. Specifically, by pressing the secondary kick arm 34, the user activates one of the torsion bars 3. The 61 moves towards the fixed post 35 in the middle, thereby generating torque in the middle of the torsion spring 36, which drives the other torsion bar 361 of the torsion spring 36 to move towards the fixed post 35. This causes the second end of the locking rocker 32 to swing towards the fixed post 35, while the first end of the locking rocker 32 swings in the opposite direction. This causes the male connecting part 311 of the locking rocker 32 to separate from the female connecting part 21 of the movable door 2, and the movable door 2 is no longer confined to the door frame 1. As a result, the user can kick open the door from both the front and back sides of the movable door 2, further optimizing the structure of the movable door 2.

[0060] Preferably, it further includes: a prompting component 4;

[0061] The prompting component 4 includes: a prompt sign 41 and a prompt reset component 42;

[0062] The door frame 1 is provided with a prompt receiving cavity 11; the prompt sign 41 is movably installed in the prompt receiving cavity 11; the prompt sign 41 is provided with a first prompt area 411 and a second prompt area 412; the door frame 1 is provided with a prompt opening 12, the prompt opening 12 exposing the first prompt area 411 or the second prompt area 412;

[0063] When the male connector 311 is connected to the female connector 21, the movable door 2 abuts against the indicator 41 and limits the indicator 41 to one location in the indicator receiving cavity 11, and the indicator opening 12 exposes the first indicator area 411; when the movable door 2 disengages from the indicator 41, the indicator reset member 42 drives the indicator 41 to move to another location in the indicator receiving cavity 11, and the indicator opening 12 exposes the second indicator area 412.

[0064] The sign 41 has a first prompt area 411 or a second prompt area 412, which can be set with prompt slogans. For example, "Kick open the door" can be set in the first prompt area 411, and "Pull close the door" can be set in the second prompt area 412. When the male connector 311 is connected to the female connector 21, the prompt opening 12 exposes the first prompt area 411, thus prompting the user to kick open the door, avoiding the user failing to open the door by hand. After the user kicks open the door according to the prompt, the male connector 311 separates from the female connector 21, the movable door 2 detaches from the sign 41, and the prompt reset component 42 automatically drives the sign 41 to move, thus exposing the second prompt area 412 of the sign 41 from the prompt opening 12, prompting the user to close the door by the handle when it is closed. After the user closes the door, the male connector 311 reconnects to the female connector 21, and the movable door 2 rests against the sign 41 again, and this cycle continues. Therefore, the prompting component 4 can prompt the user based on the status of the active door 2, ensuring a better user experience when using the kick-to-open door and avoiding problems caused by the user not knowing how to use it.

[0065] Among them, the prompt reset component 42 is a structure that drives the prompt sign 41 to move, such as a cylinder, a moving trolley, a magnet, etc., as long as the prompt sign 41 is reset and moved; taking a magnet as an example, after the male part 311 and the female part 21 are separated, the magnet attracts the metal prompt sign 41 through magnetism, thereby moving the prompt sign 41, and the second prompt area 412 of the prompt sign 41 is exposed from the prompt opening 12.

[0066] More preferably, the prompting reset element 42 includes: a prompting reset spring 421;

[0067] One end of the prompt reset spring 421 is connected to the inner wall of the prompt receiving cavity 11, and the other end of the prompt reset spring 421 is connected to the prompt sign 41.

[0068] The reset spring 421 can drive the indicator sign 41 to reset by either extending or retracting its position, depending on the set position; for example... Figure 4 When the male connector 311 is connected to the female connector 21, the movable door 2 is limited to the door frame 1. At this time, the movable door 2 presses the indicator 41 into the indicator receiving cavity 11, and the indicator return spring 421 is in a stretched state. When the male connector 311 is separated from the female connector 21, the indicator return spring 421 elastically contracts and resets the indicator 41.

[0069] The central support column 37 can be installed on the door frame 1 using a known installation method, thereby achieving a swing installation; for example, in one embodiment, a pivot is provided between the central support column 37 and the door frame 1, and a shaft is provided inside the pivot. The swing installation of the central support column 37 can be achieved by rotating the pivot.

[0070] In the preferred embodiment, the central support 37 is elastic.

[0071] The central support 37 is elastic, and it can swing within a certain angle range without the need for the pivot of the above embodiment. The main kick member 31 drives the second end of the locking rocker 32 to tilt up, and the central support 37, through elastic movement, drives the male connection part 311 of the first end of the locking rocker 32 away from the female connection part 21. When the main kick member 31 is no longer pressed, the elasticity of the central support 37 and the reset elastic member 33 are reset, and the locking rocker 32 returns from the tilted state to the straight position.

[0072] The elasticity here refers to the ability to recover from deformation. For example, soft metals or soft plastics can be used, but rubber or a combination of rubber and metal is preferred.

[0073] More preferably, it also includes: door opening drive component 5;

[0074] The door frame 1 is provided with a frame opening 13, and the movable door 2 moves within the frame opening 13; when the male connecting part 311 is connected to the female connecting part 21, the movable door 2 is limited to the first region 131 of the frame opening 13; the output end of the door opening drive assembly 5 is connected to the movable door 2 and is used to drive the movable door 2 to move to the second region 132 of the frame opening 13.

[0075] When the male connector 311 and the female connector 21 are connected, the movable door 2 is limited to the first area 131 of the frame opening 13, and the door opening drive assembly 5 will not drive the movable door 2 to move; when the male connector 311 and the female connector 21 are separated, the door opening drive assembly 5 drives the movable door 2 to move from the first area 131 to the second area 132, realizing the effect of automatic door opening after kicking, eliminating the need for the user to manually open the door, improving the door opening and closing experience, and ensuring cleanliness and hygiene.

[0076] The door opening drive assembly 5 is used to drive the movable door 2 to move at the frame opening 13. The door opening drive assembly 5 can be an electric drive mechanism or an automatic drive mechanism. The electric drive mechanism, such as a moving trolley, a robotic arm, a cylinder, or a combination of a motor and a lead screw to form a mechanism with horizontal movement drive, can actively apply external force when the movable door 2 needs to move, so as to realize the horizontal movement of the movable door 2. The automatic drive mechanism continuously applies an external force to the movable door 2. When the male part 311 is separated from the female part 21, the movable door 2 moves in the direction of the force. The automatic drive mechanism can be, for example, a spring, a magnet, etc.

[0077] In a further optimized manner, the door opening drive assembly 5 includes: a drive fixing base 51, a drive rope 52, and a drive weight 53;

[0078] The drive mounting base 51 is installed on the movable door 2; one end of the drive rope 52 is connected to the drive mounting base 51; the other end of the drive rope 52 is connected to the drive weight 53 and is located outside the frame opening 13; the drive weight 53 keeps the drive rope 52 taut by its own weight, which drives the drive mounting base 51 to move and moves the movable door 2 to the second area 132.

[0079] The drive mounting base 51 is connected to the movable door 2, and the drive weight 53 is located outside the frame opening 13. One end of the drive rope 52 is connected to the drive mounting base 51 inside the frame, and the other end extends out of the frame opening 13 and is connected to the drive weight 53. The drive weight 53 has a certain weight, and under the action of gravity, it keeps the drive rope 52 in a taut state, thereby creating a horizontal tension in the drive mounting base 51. When the male connector 311 is connected to the female connector 21, the movable door 2 is limited to the frame opening 13, and the drive mounting base 51 cannot pull the movable door 2 to move. When the male connector 311 is separated from the female connector 21, the drive mounting base 51 automatically drives the movable door 2 to move under the tension created by the drive weight 53, so that the movable door 2 automatically moves to the second area 132 at the moment the male connector 311 is separated from the female connector 21, thereby realizing the effect of automatic door opening by kicking, eliminating the need to use hands to open the door, and completely freeing the hands when opening the door.

[0080] Optimally, the door opening drive assembly 5 includes: guide wheels 54; the guide wheels 54 are connected to the door frame 1 and distributed along the length direction of the drive rope 52; the drive rope 52 is wound around the roller surface of a plurality of guide wheels 54.

[0081] The guide wheel 54 can guide the length direction of the drive rope 52, preventing the drive rope 52 from deviating from the predetermined trajectory during traction and improving the stability of the door opening; at the same time, the movement of the drive rope 52 can drive the guide wheel 54 to rotate, thereby reducing the friction between the drive rope 52 and other structures, thus improving the smoothness of the movement of the drive rope 52.

[0082] More preferably, the door opening drive assembly 5 includes: a buffer 55;

[0083] The buffer 55 is disposed below the driving weight 53 and / or on the inner wall of the second region 132; the driving weight 53 falls to abut against the buffer 55, and / or the movable door 2 moves to abut against the buffer 55.

[0084] The moment the user kicks and presses the main kick unit 31, the male connector 311 separates from the female connector 21, causing the drive weight 53 to fall and move the movable door 2 via the drive rope 52 and drive fixing seat 51. Since the drive weight 53 may fall too quickly, it can fall to the buffer 55 below, and / or the movable door 2 can move to the buffer 55 against the inner wall of the second area 132, thereby slowing down the movement of the movable door 2 and preventing damage to the surface due to excessive speed at the end point. Thus, the buffer 55 ensures that the movable door 2 moves quickly after being kicked, achieving a fast opening response, while also preventing damage due to excessive speed at the end point.

[0085] The buffer 55 can be a known buffering mechanism, such as a buffer pad, buffer wheel, or spring, which has deformable capabilities. It slows down the falling speed of the movable door 2 and / or the driving weight 53 through its own deformation or movement, thereby ensuring a reduced speed decrease at the end point. For example, in one embodiment, the buffer 55 is a spring. The spring deforms itself when it contacts the movable door 2 and / or the driving weight 53, reducing the impact on the movable door 2.

[0086] A combination door includes: a fixed door 6 and the aforementioned kick-open door structure;

[0087] The fixed door 6 is installed on the door frame 1, and the fixed door 6 is arranged parallel to the movable door 2.

[0088] The fixed door 6 can be set to be stationary, or it can be set to move along a regular track, or it can be a regular manual sliding door. Generally, the fixed door 6 is not used. When the user needs to open the door, he / she can simply kick the main kick piece 31 below to open the door.

[0089] The technical principles of this solution have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this solution and should not be construed as limiting the scope of protection of this solution in any way. Based on this explanation, those skilled in the art can readily conceive of other specific implementations of this solution without inventive effort, and these implementations will all fall within the scope of protection of this solution.
