The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
With reference to fig. 1 to 3, a mask 1 opening and closing assembly 11 for a railway vehicle according to an embodiment of the present invention includes: a frame 111, an opening and closing mechanism 112, and a driving mechanism 113.
Specifically, backbone 111 includes a first track groove 1111 and a second track groove 1112. The opening/closing mechanism 112 includes a first mounting wing 1121, a second mounting wing 1122, a first slide rail 1125 and a second slide rail 1126, the first mounting wing 1121 is movable along a first trajectory groove 1111, the second mounting wing is movable along a second trajectory groove 1112, the first mounting wing 1121 and the second mounting wing 1122 are convertible between a mutually folded state and a mutually unfolded state in the left-right direction, the first slide rail 1125 is rotatably provided on the framework 111, and the first slide rail 1125 is slidably connected to the first mounting wing 1121, the second slide rail 1126 is rotatably provided on the framework 111, and the second slide rail 1126 is slidably connected to the second mounting wing 1122. The first mounting wing 1121 and the second mounting wing 1122 can be used for mounting two half portions of the mask 1, respectively, and the two half portions of the mask 1 are opened and closed by opening and closing the first mounting wing 1121 and the second mounting wing 1122, that is, the opening and closing of the mask 1 are realized. The first mounting wing 1121 is supported by the frame 111 through the first track groove 1111, and the second mounting wing 1122 is supported by the frame 111 through the second track groove 1112.
During the movement of the mounting wings along the corresponding track grooves, the corresponding slide rails will also rotate, and the rotation of the slide rails can provide support for the mounting wings, and the shape of the slide rails can be selected according to actual needs, so that the mounting wings can be adjusted to a predetermined position through the rotation of the slide rails.
Specifically, during the movement of the first mounting wings 1121 along the corresponding first trajectory grooves 1111, the corresponding first sliding rails 1125 will also rotate, and the rotation of the first sliding rails 1125 can provide support for the first mounting wings 1121, and the shape of the first sliding rails 1125 can be selected according to actual needs, so that the first mounting wings 1121 are adjusted to a predetermined position by the rotation of the first sliding rails 1125.
During the movement of the second mounting wings 1122 along the corresponding second trajectory grooves 1112, the corresponding second sliding rails 1126 will also rotate, and the rotation of the second sliding rails 1126 can provide support for the second mounting wings 1122, and the shape of the second sliding rails 1126 can be selected as desired to adjust the second mounting wings 1122 to a predetermined position by the rotation of the second sliding rails 1126.
The driving mechanism 113 is connected to the opening/closing mechanism 112, and the opening/closing mechanism 112 can be driven to switch by the driving mechanism 113 to achieve the purpose of opening/closing the mask 1, that is, the driving mechanism 113 is used to drive the first mounting wing 1121 and the second mounting wing 1122 to switch between the states of being opened and closed. Among them, corresponding to the mask 1, the mask 1 is opened when the first and second mounting wings 1121 and 1122 are unfolded from each other, and the mask 1 is closed when the first and second mounting wings 1121 and 1122 are folded back from each other.
According to the mask 1 opening and closing assembly 11 for the railway vehicle, the blocking is avoided, and the stability is high.
Specifically, when the first trajectory groove 1111 is not an arc centered on the rotation center axis of the first rail 1125, the first attachment wing 1121 tends to move along the rotation center axis perpendicular to the first rail 1125 while the first attachment wing 1121 moves along the first trajectory groove 1111, and this movement may increase friction between the first attachment wing 1121 and the first rail 1125, which may cause the first attachment wing 1121 not to smoothly slide along the rail. In addition, due to reasons such as manufacturing accuracy, the tendency of the first mounting wings 1121 to move along the central axis of rotation perpendicular to the first slide rails 1125 can also easily cause the first mounting wings 1121 to be locked. Therefore, in the present application, the first mounting wings 1121 and the sliding rails are configured to be slidable relative to each other, and when the first mounting wings 1121 have a tendency to move along a central axis perpendicular to a rotation axis of the first sliding rails 1125, the first mounting wings 1121 can slide along the first sliding rails 1125, so that the first mounting wings 1121 can smoothly slide along the first sliding rails 1125, thereby avoiding being locked, and effectively improving the stability of the opening and closing assembly 11.
In addition, when the second trajectory groove 1112 is not an arc centered on the rotation center axis of the second slide rail 1126, the second mounting wing 1122 tends to move along the rotation center axis perpendicular to the second slide rail 1126 while the second mounting wing 1122 moves along the second trajectory groove 1112, and this movement causes friction or the like between the second mounting wing 1122 and the second slide rail 1126 to be increased, and the second mounting wing 1122 cannot smoothly slide along the slide rail. In addition, due to manufacturing accuracy and the like, the tendency of the second mounting wing 1122 to move along the direction perpendicular to the rotation center axis of the second slide rail 1126 also easily causes the second mounting wing 1122 to be locked. Therefore, in the present application, the second mounting wing 1122 and the slide rail are configured to be slidable with respect to each other, and when the second mounting wing 1122 tends to move along a direction perpendicular to the rotation center axis of the second slide rail 1126, the second mounting wing 1122 can slide along the second slide rail 1126, so that the second mounting wing 1122 can smoothly slide along the second slide rail 1126, thereby preventing the second mounting wing from being jammed and effectively improving the stability of the opening and closing assembly 11.
As can be seen from the foregoing description, in the present application, the sliding rails and the mounting wings are combined into a form capable of sliding with each other, and there is no need to have too many requirements on the shapes of the corresponding track grooves, and therefore, the shapes of the first track groove 1111 and the second track groove 1112 are not limited, and only the design requirements need to be considered, the first track groove 1111 and the second track groove 1112 are not limited to the circular arc shape, and the rotation central axes of the first sliding rail 1125 and the second sliding rail 1126 may not be collinear, and the center of the first track groove 1111 and the rotation central axis of the first sliding rail 1125, the center of the second track groove 1112 and the rotation central axis of the second sliding rail 1126 also need not be arranged in a concentric manner, and therefore, only the shapes of the components of the opening and closing mechanism 112 need to be reasonably designed according to the design requirements. But also can effectively reduce the requirement on the overall precision.
In some embodiments of the present invention, the first and second slide rails 1125, 1126 are collinear with respect to a central axis of rotation of the skeletal frame 111. Of course, as can be seen from the foregoing description, the center axis of rotation of the first slide rail 1125 relative to the skeletal frame 111 may or may not be collinear with the center axis of rotation of the second slide rail 1126 relative to the skeletal frame 111. This is determined from the actual trajectory of the opening and closing of the mask 1.
As shown in fig. 3, in some embodiments of the present invention, the first trajectory groove 1111 and the second trajectory groove 1112 are each in the shape of a circular arc, and the center of the first trajectory groove 1111, the center of the second trajectory groove 1112, the center of rotation of the first sliding rail 1125, and the center of rotation of the second sliding rail 1126 coincide or at least partially do not coincide.
That is, the center of the first track groove 1111, the center of the second track groove 1112, the center of rotation of the first slide rail 1125, and the center of rotation of the second slide rail 1126 all coincide. In addition, at least two of the center of the first track groove 1111, the center of the second track groove 1112, the center of rotation of the first slide rail 1125, and the center of rotation of the second slide rail 1126 may be arranged to be misaligned, that is, the center of the first track groove 1111, the center of the second track groove 1112, the center of rotation of the first slide rail 1125, and the center of rotation of the second slide rail 1126 may be at least partially misaligned.
Further, the first track groove 1111 and the second track groove 1112 are both arc-shaped with middle portions protruding outward in a direction away from each other. Of course, the shapes of the first trace groove 1111 and the second trace groove 1112 are not limited thereto, and the first trace groove 1111 and the second trace groove 1112 may be also provided in a straight line form, an arc shape with a convex middle portion toward a direction approaching each other, or the like according to the actual use.
Referring to fig. 3, in some embodiments of the present invention, a rotating base 1113 is disposed on the frame 111, and the first sliding rail 1125 and the second sliding rail 1126 are rotatably connected to the rotating base 1113. Accordingly, the stability of the first and second slide rails 1125 and 1126 can be improved, and the mounting and integration of the opening/closing assembly 11 can be facilitated, thereby improving the stability of the entire opening/closing assembly 11.
In some embodiments, the first slide rail 1125 is taller than the second slide rail 1126, wherein the first slide rail 1125 connects to an upper surface of the first mounting wing 1121 and the second slide rail 1126 connects to a lower surface of the second mounting wing 1122.
The first slide rail 1125 may be lower than the second slide rail 1126, or the first slide rail 1125 may be connected to the lower surface of the first mounting wing 1121 and the second slide rail 1126 may be connected to the upper surface of the second mounting wing 1122.
Thus, separating the first and second slide rails 1125, 1126 prevents interference during transition between the first and second slide rails 1125, 1126 to each other's extended and closed positions. Specifically, when the first slide rail 1125 and the second slide rail 1126 are folded, the first slide rail 1125 and the second slide rail 1126 are vertically displaced and do not interfere with each other.
Of course, the first sliding rail 1125 and the second sliding rail 1126 may be set to have the same height, and the first sliding rail 1125 and the second sliding rail 1126 may be switched between the folded state and the unfolded state through a reasonable structural design.
Preferably, the first mounting wing and the second mounting wing in the present invention may be arranged on the same horizontal plane.
