[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0036] Please also refer to Figure 1 The translation mechanism 100 provided in the embodiment of the present application is now described. The translation mechanism 100 includes: a first swing arm 11 , a second swing arm 12 and a movable arm 13 .

[0037] Specifically, the first swing arm 11 is connected to a first fixed shaft 14 , the second swing arm 12 is connected to a second fixed shaft 15 , the movable arm 13 is hinged to the first swing arm 11 through a first connecting shaft 16 , and the movable arm 13 is hinged to the second swing arm 12 through a second connecting shaft 17 .

[0038] The movable arm 13 is provided with a translation installation position 18 , and the plane positions of the translation installation position 18 , the first connecting shaft 16 and the second connecting shaft 17 form a triangle.

[0039] It can be understood that since the first swing arm 11 is connected to the first fixed shaft 14, the first swing arm 11 always rotates around the first fixed shaft 14 during the rotation process. Similarly, the second swing arm 12 is connected to the second fixed shaft 15, the second swing arm 12 always rotates around the second fixed shaft 15 during the rotation process.

[0040] Because the movable arm 13 is hinged to the first swing arm 11 through the first connecting shaft 16, and the movable arm 13 is hinged to the second swing arm 12 through the second connecting shaft 17, the first swing arm 11, the second swing arm 12 and the movable arm 13 form a connecting rod mechanism with both ends fixed.

[0041] Based on the above, since the movable arm 13 is provided with a translation mounting position 18, the planar positions of the translation mounting position 18, the first connecting axis 16, and the second connecting axis 17 form a triangle. The first swing arm 11 and the second swing arm 12 jointly limit the displacement and rotation angle of the movable arm 13. When the translation mounting position 18 is provided on the movable arm 13, the movement trajectory of the translation mounting position 18 is necessarily fixed.

[0042] If so, please also refer to Figure 2 Point A represents the position of the first fixed axis 14, point B represents the position of the second fixed axis 15, L1 represents the length of the first swing arm 11, and L2 represents the length of the second swing arm 12. When the first swing arm 11 and the second swing arm 12 jointly limit the displacement and rotation angle of the movable arm 13, the first swing arm 11 is rotated clockwise by a certain angle to generate the motion trajectory C of the first connecting axis 16, the motion trajectory D of the second connecting axis 17, the motion trajectory E of the translation mounting position 18, and the motion trajectory F of the midpoint of the first connecting axis 16 and the second connecting axis 17.

[0043] As can be seen from the figure, when the first swing arm 11 rotates clockwise by a certain angle, the movable arm 13, on the one hand, follows the first swing arm 11 to rotate clockwise with point A as the center, and its expected trajectory is trajectory C. The motion trajectory C is actually a downward arc; at the same time, the movable arm 13 is restricted by the second swing arm 12 on the other hand, and its expected motion trajectory is a circular arc moving upward with the first connecting shaft 16 as the center. After the two phases offset each other, it corresponds to the actual motion trajectory E.

[0044] In addition, since the planar positions of the translation mounting position 18, the first connecting axis 16 and the second connecting axis 17 form a triangle, that is, the translation mounting position 18 is outside the connecting line between the first connecting axis 16 and the second connecting axis 17, compared with the motion trajectory F of the midpoint of the first connecting axis 16 and the second connecting axis 17, the motion trajectory E approaches a straight line, and when the translation mounting position 18 is farther away from the midpoint of the first connecting axis 16 and the second connecting axis 17, the motion trajectory E approaches a straight line within a certain angle range of rotation of the first swing arm 11.

[0045] In this way, compared with the traditional guide rail guiding mechanism, the above-mentioned translation mechanism 100 can realize the translation guiding function through the form of a connecting rod. The first swing arm 11, the second swing arm 12 and the movable arm 13 adopt an articulated structure to reduce wear and noise, increase service life, and can solve the problem of condensation of the existing translation guide rail under adjustment under extremely cold conditions. The translation length it can provide can be greater than the space occupied length of the entire mechanism, reducing the length requirement of the space.

[0046] Compared with the prior art, the translation mechanism 100 provided in the present application is provided with a first swing arm 11, a second swing arm 12 and a movable arm 13. The first swing arm 11 is connected to a first fixed axis 14, the second swing arm 12 is connected to a second fixed axis 15, the movable arm 13 and the first swing arm 11 are hinged by a first connecting axis 16, the movable arm 13 and the second swing arm 12 are hinged by a second connecting axis 17, and a translation mounting position 18 is provided on the movable arm 13. The planar positions of the translation mounting position 18, the first connecting axis 16 and the second connecting axis 17 form a triangle, and the translation guide function is realized in the form of a connecting rod, which can reduce wear and noise, improve service life, and operate against condensation in extremely cold conditions, improve service life and stability, while also reducing space requirements.

[0047] In another embodiment of the present application, the distance from the translation installation position 18 to the first connecting axis 16 is equal to the distance from the translation installation position 18 to the second connecting axis 17 .

[0048] It can be understood that when the distance from the translation mounting position 18 to the first connecting axis 16 is equal to the distance from the translation mounting position 18 to the second connecting axis 17, the first connecting axis 16, the second connecting axis 17 and the position of the translation mounting position 18 form an isosceles triangle, so that the motion trajectory E of the translation mounting position 18 is a left-right symmetrical line segment. When other influences are adjusted to a certain extent, the amplitude generated by the translation mounting position 18 during the movement is minimized, which is beneficial to improving the stability of the translation mechanism 100 during the reciprocating motion.

[0049] Furthermore, the distance from the first fixed axis 14 to the first connecting axis 16 is equal to the distance from the second fixed axis 15 to the second connecting axis 17 .

[0050] It can be understood that when the distance from the first fixed axis 14 to the first connecting axis 16 is equal to the distance from the second fixed axis 15 to the second connecting axis 17, the rate of change of the external force required by the translation mechanism 100 during the reciprocating motion is smaller, and the movement speed of the translation mounting position 18 approaches a uniform speed, which is beneficial to improving the stability of the translation mechanism 100 during the reciprocating motion.

[0051] See also Figures 3 to 6 The present application also provides a sliding door 200, which includes a gate 21, a driving mechanism 22 and two sliding mechanisms 100 as described above.

[0052] The gate 21 is hinged to the translation installation position 18 of each translation mechanism 100 at the same time, and the driving mechanism 22 is used to drive the translation mechanism 100 to swing synchronously.

[0053] It can be understood that when the gate 21 has two translation mechanisms 100 driven simultaneously, it can reduce the shaking of the gate 21 during the movement. The most important point is that when the gate 21 is hinged to the two translation mounting positions 18, the angle of the gate 21 can be limited to deflect, so that the gate 21 only translates and does not flip over itself.

[0054] Compared with the prior art, the sliding door 200 provided in the present application can reduce the shaking of the gate 21 during movement and limit the angle deflection of the gate 21 by hingedly connecting the gate 21 to the translation mounting position 18 of each translation mechanism 100 at the same time, thereby further improving the stability of the sliding door 200.

[0055] In another embodiment of this application, please refer to Figures 3 to 6 The sliding door 200 also includes a first connecting rod 23 and a second connecting rod 24. The two ends of the first connecting rod 23 are respectively hinged to the same position of the first swing arms 11 of the two translation mechanisms 100, and the two ends of the second connecting rod 24 are respectively hinged to the same position of the second swing arms 12 of the two translation mechanisms 100.

[0056] It is understood that by correspondingly connecting the first swing arms 11 and the second swing arms 12 of the two translation mechanisms 100 via the first connecting rod 23 and the second connecting rod 24, the swinging motions of the two translation mechanisms 100 are kept consistent, thereby further improving the translational stability of the gate 21. Furthermore, a single drive mechanism 22 can be used to simultaneously drive the two translation mechanisms 100, thereby reducing costs and simplifying the structure.

[0057] In another embodiment of this application, please refer to Figures 3 to 6 The driving mechanism 22 includes a motor 221, a crank 222 and a third swing arm 223. The output end of the motor 221 is fixedly connected to the crank 222. The crank 222 is hinged to the third swing arm 223 through a third connecting shaft 224. The third swing arm 223 is hinged to the first swing arm 11 or the second swing arm 12 of any one of the translation mechanisms 100 through a fourth connecting shaft 225.

[0058] It is understood that, driven by the motor 221, the crank 222 rotates, driving the third swing arm 223 to swing the sliding door 200. Assuming the rotation center of the crank 222 is point M, the rotation center of the third connecting shaft 224 is point K, and the rotation center of the fourth connecting shaft 225 is point N, when the gate 21 is in the closed state, a straight line NMK can be formed. If the gate 21 is pushed at this time, the third swing arm 223 will be subjected to an external force parallel to the straight line NMK, and thus the locking structure cannot be destroyed, thereby preventing the gate 21 from being maliciously pushed open. However, if the motor 221 is controlled to rotate, the motor 221 drives the crank 222 to rotate, applying a torque perpendicular to the straight line NMK, which can easily destroy the locking structure, so that normal door opening is not affected.

[0059] Similarly, when the gate 21 is open, a straight line NKM is formed. At this point, pushing the third swing arm 223 of the gate 21 will be subject to an external force parallel to the straight line NKM, preventing the locking mechanism from being broken, thus preventing the gate 21 from being maliciously closed. However, by controlling the rotation of the motor 221, the motor 221 drives the crank 222 to rotate, applying a torque perpendicular to the straight line NKM, which can easily break the locking mechanism, thus preserving normal door closing.

[0060] For further information, see Figures 3 and 4 The sliding door 200 further includes a base plate 25 , on which the first fixed shaft 14 , the second fixed shaft 15 and the motor 221 of the sliding mechanism 100 are fixed.

[0061] For further information, please also refer to Figure 8, a plurality of avoidance holes 251 are provided on the base plate 25, the third swing arm 223 includes a first side rod 2231, a second side rod 2232 and an intermediate rod 2233, the crank 222 is hinged to the first side rod 2231 through a third connecting shaft 224, the first side rod 2231 is fixedly connected to the intermediate rod 2233, the intermediate rod 2233 is fixedly connected to the second side rod 2232 after passing through the avoidance hole 251, and the second side rod 2232 is hinged to any one of the first swing arms 11 or the second swing arm 12 of the translation mechanism 100 through a fourth connecting shaft 225.

[0062] It can be understood that by setting the first side rod 2231, the second side rod 2232 and the middle rod 2233, the first side rod 2231 and the second side rod 2232 are respectively located on both sides of the base plate 25 and swing. On the one hand, it can prevent interference between the various structures, and on the other hand, it can make each component approach the plane where the base plate 25 is located, thereby improving the stability of each connecting rod and the swing arm during movement.

[0063] For further information, please also refer to Figures 7 to 9 The sliding door 200 also includes an unlocking mechanism 26, which is arranged on one side of the driving mechanism 22. The unlocking mechanism 26 includes an elastic reset member 261 and a pendulum 262. The third swing arm 223 is provided with a protruding structure 2234 extending toward the side close to the unlocking mechanism 26. The elastic reset member 261 is connected to the pendulum 262 and is used to drive the pendulum 262 to reset. When the pendulum 262 swings, it can contact the protruding structure 2234 or the crank 222.

[0064] It can be understood that when the driving mechanism 22 of the sliding door 200 fails, the gate 21 will be restricted by the locking structure and cannot move. The unlocking mechanism 26 can be used as an alternative solution, that is, when the gate 21 is in the closed state, the pendulum 262 is manually rotated, the pendulum 262 can collide with the crank 222, and the crank 222 rotates to destroy the locking structure; when the gate 21 is in the open state, the pendulum 262 is manually rotated, the pendulum 262 can collide with the protruding structure 2234, and the third swing arm 223 rotates to destroy the locking structure, thereby obtaining a temporary solution for opening and closing the door when the driving mechanism 22 fails.

[0065] The present application also provides a channel gate, which includes the sliding door 200 as described above.

[0066] The sliding door 200 can achieve a large range of displacement in a narrow channel, thereby reducing the space occupied by the channel gate itself. Compared with the traditional gate guided by slide rails, it can reserve a larger space for pedestrian passage. Compared with the traditional gate guided by swing gates, it can prevent the door from interfering with pedestrians.

[0067] Compared with the prior art, the channel gate provided in the present application adopts the sliding door 200 as described above. After being set in the channel, it can reduce the space occupation requirement, increase the speed of opening and closing the door, and has the ability to work normally in a cold environment.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
