That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. Also, unless otherwise indicated, like reference numerals may be used to identify corresponding elements in different figures. The drawings are for clarity of understanding, and do not show actual dimensions of the elements.
Please refer to fig. 1 and fig. 2. Fig. 1 is a front perspective view of a door opening and closing mechanism 10 according to an embodiment of the present invention. Fig. 2 is a perspective rear view of the door opening and closing mechanism 10 in fig. 1.
As shown in fig. 1 and 2, the door opening and closing mechanism 10 includes a door module 100 and a switch module 200. The door module 100 includes a housing 110, a door shaft 120, and a plate body 130. The switch module 200 includes a rotating shaft 210, a reset member 220 and a pressing portion 230.
As shown in fig. 1 and 2, the housing 110 has an opening, and the door shaft 120 is disposed on one side of the opening. And the plate body 130 is pivotally connected to the door spindle 120 and covers the opening. In the embodiment shown in fig. 1, the plate body 130 is rotatable with respect to the door shaft 120. In some embodiments, the door shaft 120 is integrally formed with the plate body 130, and the door shaft 120 is rotatable with respect to the housing 110. In other embodiments, the door shaft 120 is integrally formed with the housing 110, and the plate 130 is rotatable with respect to the door shaft 120. It should be understood that any pivoting mechanism that enables the plate 130 to rotate relative to the housing 110 may be implemented by one skilled in the art.
The door opening and closing mechanism 10 is shown in a fixed state in fig. 1 and 2. In the door opening and closing mechanism 10 in the fixed state, the plate body 130 is caught by the switch module 200 and cannot arbitrarily rotate along the door shaft 120. In the proposed embodiment of the present invention, the switch module 200 is disposed at a side of the opening of the housing 110 opposite to the door shaft 120. The plate body 130 and the switch module 200 are each provided with a plurality of protrusions corresponding to each other at a side edge with respect to the door shaft 120. Specifically, the plate body 130 is further provided with a first protrusion 140 and a second protrusion 150, and the switch module 200 is further provided with a third protrusion 240 and a fourth protrusion 250. Through the buckling relation of the convex parts, the door cover opening and closing mechanism 10 provided by the invention can achieve the effects of single-hand operation, loss rate reduction and the like. The relative positions and the actuation relationship of the respective projections in the door opening and closing mechanism 10 will be described in detail below.
Referring to fig. 3, a cross-sectional view of the door opening and closing mechanism 10 along line 3-3 of fig. 1 is shown. As shown in fig. 3, the plate body 130 is provided with a first protrusion 140 on a side away from the door shaft 120 (see fig. 1), and a second protrusion 150 is provided on the first surface 130a of the plate body 130. The switch module 200 is provided with a third protrusion 240 and a fourth protrusion 250 connected to the rotating shaft 210. Specifically, the third protruding portion 240 and the pressing portion 230 are connected to the rotating shaft 210 together through the first connecting portion 260, and the fourth protruding portion 250 is connected to the rotating shaft 210 through the second connecting portion 270. In fig. 3, the door cover fixing mechanism 10 is in a fixed state, that is, the plate body 130 is located at the first position, and the pressing portion 230 is located at the initial position. In the fixed state, the first surface 130a of the plate body 130 is perpendicular to the first connection portion 260. In the present embodiment, the first connection portion 260 is vertically connected to the second connection portion 270. However, in other embodiments, a person skilled in the art can freely select the first connecting portion 260 and the second connecting portion 270 having different shapes, and the invention is not limited thereto.
In the present embodiment, the pressing part 230 is coplanar with the third protrusion 240. In addition, the plate body 130 has a second surface 130b opposite to the first surface 130 a. In the fixed state, the pressing portion 230 is further coplanar with the second surface 130b in addition to being coplanar with the third protrusion 240. Through the arrangement, the switch module 200 is integrally more smooth and attractive.
As shown in fig. 3, when the door opening and closing mechanism 10 is in the fixed state, the third projection 240 is adjacent to a surface of the first projection 140 away from the first surface 130 a. While fourth projection 250 is adjacent to second projection 150. With the above arrangement, in the fixing state, the first protrusion 140 and the second protrusion 150 are sandwiched between the third protrusion 240 and the fourth protrusion 250. In this way, when the plate 130 rotates clockwise along the door shaft 120 as shown in fig. 3, the fourth protrusion 250 abuts against the second protrusion 150, and the force applied to the rotating shaft 210 by the reset element 220 prevents the plate 130 from further rotating. When the plate 130 rotates along the door shaft 120 in the counterclockwise direction in the drawing of fig. 3, the third protrusion 240 abuts against the first protrusion 140, and the force applied to the rotating shaft 210 by the reset element 220 prevents the plate 130 from further rotating.
Specifically, in this embodiment, the restoring member 220 is a knob spring. However, a person skilled in the art can select any reset mechanism that can make the pressing portion 230 return to the initial position without external force, and the reset element 220 of the present invention is not limited to a knob spring.
The engagement relationship between the switch module 200 and the door module 100 when the door opening/closing mechanism 10 is in the fixed state has been described above. When the user wants to open the plate 130, the user only needs to press the pressing portion 230 of the switch module 200 to release the fixed state, so that the plate 130 can be separated from the control of the switch module 200 and freely rotate along the door shaft 120. Please refer to fig. 4 to fig. 7 for a specific operation flow.
Referring first to fig. 4, a stage after the user presses the pressing portion 230 of fig. 3 is shown. As shown in fig. 4, the user presses the pressing portion 230 clockwise in the drawing, so that the pressing portion 230 rotates clockwise around the rotating shaft 210. The third protrusion 240 and the fourth protrusion 250 connected to the rotating shaft 210 rotate clockwise along the rotating shaft 210 together with the pressing portion 230. The fourth protrusion 250 of the switch module 200 rotates clockwise and abuts against the second protrusion 150 of the door module 100, and applies a force to the second protrusion 150 to lift the plate 130. The third protrusion 240 of the switch module 200 gradually moves away from the first protrusion 140 during the clockwise rotation along the rotation axis 210.
As shown in fig. 4, in the present embodiment, in order to enable the fourth protrusion portion 250 to push the plate body 130 more smoothly, the surface of the fourth protrusion portion 250 facing the plate body 130 has an inclined design. That is, the surface of the fourth protrusion 250 facing the plate body 130 is not a flat plane. Specifically, a portion of the fourth protrusion 250 adjacent to the door shaft 120 is designed as a wedge portion 250 a. In this way, the contact area between the fourth protrusion 250 and the second protrusion 150 is uniform and smooth when the second protrusion pushes the second protrusion. Through the above design, abrasion of the second protrusion 150 and the fourth protrusion 250 can be avoided.
Referring next to fig. 5, a cross-sectional view of the door opening and closing mechanism 10 is shown at a next stage of fig. 4. Continuing with fig. 4, after the third protrusion 240 rotates clockwise along the rotation axis 210 and completely leaves the first protrusion 140, the plate 130 can freely rotate counterclockwise along the door axis 120.
In the stage of fig. 5, while pressing the pressing portion 230, the user can lift the plate 130 with the other hand to expose the opening in the housing 110, so as to achieve the opening function of the switch module 200. However, the second protrusion 150 of the present embodiment also has a groove portion 150a with the plate body 130 at an end away from the door shaft 120, and the groove portion 150a is matched with the wedge portion 250a of the fourth protrusion 250. With the above arrangement, the user can smoothly open the plate 130 without continuously pressing the pressing portion 230. In particular, reference may be made to fig. 6.
Fig. 6 shows a sectional view of the door opening and closing mechanism 10 at the next stage of continuing fig. 5. As shown in fig. 6, the wedge portion 250a of the fourth projecting portion 250 is caught in the groove portion 150a of the second projecting portion 150, so that the door cover fixing mechanism 10 is in a pressed state. In the pressed state, the plate body 130 is located at the second position, and the pressing portion 230 is located at the pressing position. Specifically, at this time, the user can stop pressing the pressing part 230. Although the reset member 220 applies a moment to the rotation shaft 210 to rotate counterclockwise in the drawing, the wedge portion 250a may be caught in the groove portion 150a, so that the rotation shaft 210 cannot be rotated by the reset member 220.
In fig. 6, in order to more perfectly engage the recessed groove portion 150a and the wedge portion 250a, the contour of the recessed groove portion 150a is identical to the wedge portion 250 a. Specifically, the contour of the groove portion 150a is also a wedge type having an angle completely equal to that of the wedge portion 250 a. In other embodiments, the angles are not necessarily all equal, and those skilled in the art can adjust the profile relationship between the groove portion 150a and the wedge portion 250a according to practical requirements.
As shown in fig. 6, in a state that the wedge portion 250a is caught in the groove portion 150a, the user may pull up the first protrusion 140 to lift the plate body 130. At this time, the second protrusion 150 pushes the fourth protrusion 250 to rotate clockwise along the rotation axis 210 until the wedge portion 250a is separated from the groove portion 150 a. Because of the matching design of the groove portion 150a and the wedge portion 250a with each other, the contact area of the two is large and smooth during the pushing process. With the above design, abrasion between the groove portion 150a and the wedge portion 250a can be avoided.
When the wedge portion 250a is completely separated from the groove portion 150a, the plate 130 is completely free from the interference of the switch module 200, and the user can freely rotate the plate 130. And at the same time the reset member 220 rotates the rotation shaft 210 back to the original position (as shown in fig. 3).
Referring to fig. 7, a cross-sectional view of the door opening and closing mechanism 10 in the open state is shown. When the user wants to return the plate 130 to the fixed state shown in fig. 3, the user only needs to push the plate 130 clockwise along the door shaft 120. As shown in fig. 7, the first protrusion 140 moves clockwise along with the plate 130 and abuts against the third protrusion 240. Then, the first protrusion 140 pushes the third protrusion 240, so that the third protrusion 240 moves clockwise in the drawing. While the third protrusion 240 moves clockwise, the third protrusion 240 gradually moves away from the first protrusion 140. When the surfaces of the third protrusion 240 and the first protrusion 140 abutting against each other completely separate from each other, the first protrusion 140 is no longer blocked by the third protrusion 240, and can smoothly enter the space between the third protrusion 240 and the fourth protrusion 250. Subsequently, the reset member 220 will restore the third protrusion 240 and the fourth protrusion 250 to the original positions, and the door opening and closing mechanism 10 is returned to the fixed state shown in fig. 3.
As shown in fig. 7, in order to make the first protrusion 140 push the third protrusion 240 more smoothly, the abutting surfaces of the first protrusion 140 and the third protrusion 240 are designed to be inclined. Specifically, the first protrusion 140 has a first inclined surface 140a on a surface close to the first surface 130a, and the third protrusion 240 has a second inclined surface 240a on a surface far from the rotation shaft 210. In the present embodiment, the first slope 140a and the second slope 240a are inclined at the same angle. Specifically, referring to fig. 3, the included angle between the first surface 130a and the first inclined surface 140a is equal to the included angle between the first surface 130a and the second inclined surface 240 a. In this way, the contact area between the first protrusion 140 and the third protrusion 240 is larger and smoother when the first protrusion pushes the third protrusion. Through the above design, abrasion of the first protrusion 140 and the third protrusion 240 can be avoided.
The first protruding part and the second protruding part are designed on the door cover module of the door cover fixing mechanism, and the third protruding part and the fourth protruding part corresponding to the switch module are designed on the switch module, so that the switch function of the door cover fixing mechanism is achieved. And the first bulge and the third bulge are designed into mutually matched inclined planes, so that the abrasion of the first bulge and the third bulge in the switching process is reduced. The wedge-shaped part is designed on the fourth protruding part, the groove part is designed between the second protruding part and the plate body, and the wedge-shaped part is clamped into the groove part when a user presses the pressing part to a certain position, so that the user does not need to continuously press the pressing part and does not worry about that the door plate falls back to the first position of the fixed state.
The present invention has been described by way of example and in the foregoing embodiments, and it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, the invention is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Accordingly, the claims are to be accorded the widest interpretation so as to encompass all such modifications and similar arrangements.
