The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0040] Wing gates are widely used in high-traffic locations such as subway stations, tourist attractions, and office buildings. When a pedestrian passes through the gate, the gate wings automatically open to allow passage. Once the pedestrian has passed, the gate wings automatically close. However, if the gate malfunctions, there is a risk of someone being pinched by the gate wings. Existing anti-pinch gates typically use sensors such as pressure sensors and infrared sensors. When the sensors detect a potential pinching hazard, they drive the gate wings open to prevent the pedestrian from being pinched. However, these anti-pinch gates are complex and costly, and if the sensors fail, the anti-pinch function may fail.

[0041] In order to solve the above problems, Figures 1 to 9As shown, the present invention first provides a door wing 100, which can prevent pedestrians from being pinched and has a simple structure and low cost.

[0042] like Figure 1 、 Figure 5 and Figure 6 As shown, specifically, the door wing 100 includes a first wing 1 and a second wing 2, wherein: the first wing 1 is used to be arranged on the gate body 200, and the first wing 1 can be rotated to open or close around a first rotation axis a relative to the gate body 200, and the first rotation axis a is located at one end of the first wing 1; the second wing 2 is arranged at an end of the first wing 1 away from the first rotation axis a, and the second wing 2 can be rotated to open or close around a second rotation axis b relative to the first wing 1, and the second rotation axis b is located at an end of the second wing 2 close to the gate body 200.

[0043] In the door wing 100 provided by the embodiment of the present invention, when a pedestrian passes through the wing gate, the door wing 100 can rotate relative to the gate body 200 around the first rotation axis a along the -X direction, so that the end of the door wing 100 away from the first rotation axis a is close to the gate body 200 and away from pedestrians or objects. At this time, the door wing 100 is in an open state to allow pedestrians to pass; after the pedestrian passes through the wing gate, the door wing 100 can rotate relative to the gate body 200 around the first rotation axis a along the +X direction, so that the end of the door wing 100 away from the first rotation axis a is away from the gate body 200. At this time, the door wing 100 is in a closed state. When the door wing 100 is in a normal working state, the second wing plate 2 is in a state as shown in FIG. Figure 5 In the closed state shown, since the second wing plate 2 is arranged at the end of the first wing plate 1 away from the first rotation axis a, the second wing plate 2 is away from the gate body 200 relative to the first wing plate 1 and close to the pedestrian or object. When the second wing plate 2 collides with the pedestrian or object, the second wing plate 2 will rotate relative to the first wing plate 1 around the second rotation axis b along the -Y direction to Figure 6 In the open position shown, the second wing 2 is positioned close to the gate body 200 and away from pedestrians or objects, acting as a buffer to prevent the door wing 100 from pinching pedestrians and improving the safety of the gate. After a pedestrian passes through, the second wing 2 can rotate relative to the first wing 1 about the second rotation axis a in the +Y direction to the closed position. Furthermore, the door wing 100 has a simple structure and does not require sensors or other components, thus avoiding the possibility of sensor damage and resulting in anti-pinch failure. Furthermore, production and maintenance costs are low.

[0044] Among them, the first rotation axis a is preferably parallel to the length direction of the gate body 200. Of course, the first rotation axis a can also form a smaller angle with the length direction of the gate body 200, as long as it is ensured that when the door wing 100 rotates relative to the gate body 200 around the first rotation axis a along the -X direction, the end of the door wing 100 away from the first rotation axis a can be close to the gate body 200 and away from pedestrians or objects; the second rotation axis b is preferably parallel to the first rotation axis a. Of course, the second rotation axis b can also form a smaller angle with the first return axis a, as long as it is ensured that when the second wing plate 2 rotates relative to the first wing plate 1 around the second rotation axis b along the -Y direction to the open state, the second wing plate 2 can be close to the gate body 200 and away from pedestrians or objects. The embodiments of the present utility model do not make specific restrictions here.

[0045] like Figure 1 As shown, the door wing 100 further includes a first rotating shaft 6 extending along the first rotation axis a, and the first wing plate 1 is rotatably connected to the gate body 200 via the first rotating shaft 6 .

[0046] like Figures 5 and 6 As shown, the door wing 100 further includes a connecting assembly 3, which includes a first connecting member 31 and a second connecting member 32 that are detachably connected. One of the first connecting member 31 and the second connecting member 32 is provided on the first wing panel 1, and the other is provided on the second wing panel 2. When the second wing panel 2 is in the closed state, the first connecting member 31 is connected to the second connecting member 32. When the second wing panel 2 is in the closed state, the first connecting member 31 is connected to the second connecting member 32 to ensure the stability and reliability of the connection between the second wing panel 2 and the first wing panel 1 in the closed state, thereby ensuring the stability of the door wing 100 in normal working conditions. When the second wing panel 2 collides with a pedestrian or an object, the second wing panel 2 will be subjected to the direction such as Figure 1 The force in the -Y direction causes the first connecting member 31 to be disengaged from the second connecting member 32 , and the second wing 2 can rotate relative to the first wing 1 around the second rotation axis b in the -Y direction to an open state.

[0047] like Figures 5 and 6 As shown, in one embodiment, the first connecting member 31 is configured as a slot, and the second connecting member 32 is configured as a block that can engage with the slot. The block and the slot are detachably engaged, and the structure of the connecting assembly 3 is simple, which is convenient for processing and assembly.

[0048] like Figure 7As shown, the slot includes a connecting section 311 and an open section 312, which extend radially along the connecting section 311. When the second wing 2 moves from an open state to a closed state, the block engages the connecting section 311 from the open section 312. Conversely, when the second wing 2 moves from a closed state to an open state, the block disengages from the open section 312 from the connecting section 311. The connecting section 311 ensures the stability and reliability of the block's engagement with the slot, thereby improving the stability and reliability of the connection between the second wing 2 and the first wing 1 in the closed state. The open section 312 facilitates the block's engagement and disengagement from the connecting section 311. Specifically, when the slot is provided on the first wing 1 and the block is provided on the second wing 2, the open section 312 faces the second wing 2. When the block is provided on the first wing 1 and the slot is provided on the second wing 2, the open section 312 faces the first wing 1. Furthermore, the opening of the open section 312 gradually increases outward from the engaging section 311 , so as to guide the engaging block when it engages the engaging section 311 from the open section 312 .

[0049] Of course, in other embodiments, the first connecting member 31 and the second connecting member 32 can also be detachably connected by other means such as plugging, magnetism, etc., as long as the stability and reliability of the connection between the second wing panel 2 and the first wing panel 1 in the closed state are guaranteed, and when the second wing panel 2 collides with a pedestrian or object, the first connecting member 31 and the second connecting member 32 can be detached. The embodiments of the present invention do not impose specific restrictions here.

[0050] like Figure 4 As shown, in one embodiment, the connecting assembly 3 is disposed at one end of the first wing 1 and the second wing 2 away from the second rotation axis b. This allows the distance between the connecting assembly 3 and the second rotation axis b to be greater. When the first connecting member 31 is connected to the second connecting member 32, the connecting assembly 3 provides a greater torque in the +Y direction to the second wing 2, thereby further improving the stability and reliability of the connection between the second wing 2 and the first wing 1 in the closed state, and improving the stability of the door wing 100 in normal working conditions. Of course, in other embodiments, the connecting assembly 3 can also be disposed at other positions of the first wing 1 and the second wing 2. As long as the first connecting member 31 can be connected to the second connecting member 32 when the second wing 2 is in the closed state, the embodiment of the utility model does not impose any specific restrictions on this.

[0051] like Figures 2 to 3As shown, the door wing 100 also includes a second shaft 4 extending along the second rotation axis. The second flap 2 is rotatably connected to the first flap 1 via the second shaft 4. The door wing 100 also includes a torsion spring 5 mounted on the second shaft 4. The two torsion arms of the torsion spring 5 are connected to the first flap 1 and the second flap 2, respectively, and the torsion spring 5 is in a torsion state. The torsion spring 5 can also provide a torque in the +Y direction to the second flap 2, thereby further improving the stability and reliability of the connection between the second connector 32 and the first connector 31, the stability and reliability of the connection between the second flap 2 and the first flap 1 when closed, and the stability of the door wing 100 during normal operation. Specifically, after the two torsion arms of the torsion spring 5 are connected to the first flap 1 and the second flap 2, respectively, the two torsion arms of the torsion spring 5 have a pre-deformed angle θ and can provide a torque in the +Y direction to the second flap 2. When the second flap 2 moves from the closed state to the open state, the deformation angle of the two torsion arms of the torsion spring 5 increases, and the torque in the +Y direction applied to the second flap 2 also increases.

[0052] like Figure 3 As shown, after the second shaft 4 passes through the first wing plate 1 and the second wing plate 2, both ends are fixed and limited by the stoppers 7 to ensure the stability and reliability of the connection between the second shaft 4, the first wing plate 1 and the second wing plate 2.

[0053] like Figure 2 As shown, the first wing panel 1 includes a first plate body 11 and a first protective member 12 covering the first plate body 11; the second wing panel 2 includes a second plate body 21 and a second protective member 22 covering the second plate body 21. The first plate body 11 and the second plate body 21 provide support, and the first and second protective members 12 and 22 can be made of a flexible material. When the first wing panel 1 or the second wing panel 2 collides with a pedestrian or object, the first and second protective members 12 and 22 can act as a buffer, further preventing the door wing 100 from pinching the pedestrian and improving the safety of the wing gate.

[0054] In one embodiment, the first plate 11 and the second plate 21 are configured as sheet metal parts to ensure the strength and reliability of the first wing panel 1 and the second wing panel 2. The first protective member 12 and the second protective member 22 are configured as polyurethane parts. Polyurethane has the characteristics of high strength, high elasticity, high wear resistance and high tear resistance. It can play a buffering role when the first wing panel 1 or the second wing panel 2 collides with pedestrians or objects. At the same time, it can also ensure the strength of the first wing panel 1 and the second wing panel 2, extend the service life of the door wing 100, and the polyurethane parts are also easy to process and form. Of course, in other embodiments, the first plate 11 and the second plate 21 can also be made of other high-strength materials such as stainless steel, and the first protective member 12 and the second protective member 22 can also be made of other flexible materials such as silicone rubber and foam. The embodiment of the utility model does not make specific restrictions here.

[0055] like Figure 2 As shown, in one embodiment, the first plate 11 is rotatably connected to the second plate 21 via the second shaft 4. One of the first connecting member 31 and the second connecting member 32 is provided on the second plate 21, and the other is provided on the first protective member 12. In the assembled state, the second protective member 22 can be covered outside the connecting component 3 so that the connecting component 3 is not exposed to ensure a neat appearance. Of course, in other embodiments, the second shaft 4 can also be connected to the first protective member 12 or the second protective member 22 according to actual needs, or one of the first connecting member 31 and the second connecting member 32 can be provided on the second protective member 22 and the other can be provided on the first plate 11. The embodiments of the present utility model do not impose specific restrictions on this.

[0056] like Figure 1 、 Figure 8 and Figure 9 As shown, an embodiment of the present invention further provides a wing gate, comprising a gate body 200 and the aforementioned door wing 100. Specifically, the gate body 200 comprises a housing 202 and a fixing member 201 disposed within the housing 202. The housing 202 is provided with an escape hole 203, and the first wing plate 1 is rotatably connected to the fixing member 201 via a first rotating shaft 6. When a pedestrian passes through the wing gate, the door wing 100 can rotate relative to the gate body 200 about the first rotation axis a in the -X direction, allowing the door wing 100 to retract into the housing 202 through the escape hole 203. After the pedestrian passes through the wing gate, the door wing 100 can rotate relative to the gate body 200 about the first rotation axis a in the +X direction, allowing the door wing 100 to extend out of the housing 202 through the escape hole 203.

[0057] In one embodiment, there are two gate bodies 200 and two door wings 100. The two gate bodies 200 are arranged in parallel and spaced apart, and the two door wings 100 are respectively arranged on opposite sides of the two gate bodies 200. A passage for pedestrians to pass through is formed between the two gate bodies 200. When pedestrians pass through the passage, the two door wings 100 simultaneously rotate relative to the corresponding gate bodies 200 to an open state, at which point the passage is opened; after pedestrians pass through the passage, the two door wings 100 simultaneously rotate relative to the gate bodies 200 to a closed state, at which point the passage is closed. In another embodiment, there can also be only one gate body 200 and one door wing 100. The gate body 200 cooperates with an external wall or other structure to form a passage for pedestrians to pass through, and the door wing 100 is arranged on the side of the gate body 200 facing the external wall or other structure.

[0058] like Figure 1As shown, the wing gate also includes a driver 300 and a linkage assembly 400. The driver 300 is mounted on the gate body 200, and the two ends of the linkage assembly 400 are connected to the output end of the driver 300 and the first wing plate 1, respectively. The driver 300 is mounted on the fixed member 201. The driver 300 can drive the linkage assembly 400 to rotate the door wing 100 relative to the gate body 200 about the first rotation axis a in the -X direction to open or in the +X direction to close. It should be noted that the linkage assembly 400 is a conventional linkage structure for wing gates, and therefore its specific structure is not detailed here.

[0059] Furthermore, when the door wing 100 collides with a pedestrian or an object, the current value of the driving member 300 will increase. When the current value of the driving member 300 exceeds the threshold value set by the program, the driving member 300 can drive the connecting rod group 400 to drive the door wing 100 to rotate and open along the -X direction relative to the gate body 200 around the first rotation axis a, thereby further preventing the door wing 100 from pinching pedestrians and improving the safety of the wing gate.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
