As shown in FIG. 1 and FIG. 6, The cross-section of the coupling section 122 is in a non-circular configuration, e.g., D-shaped. The sleeve piece 134 encapsulates the coupling section 122, and the non-circular cross-section prevents the sleeve piece 134 from rotating with respect to the shaft 120. The cross-section of the coupling section 122 can also be rectangular, triangular, or other non-circular shape. Or the surface of the coupling section 122 is provided with an anti-slip pattern or convex and concave structures parallel to the axis, such that its cross-section is non-circular. In addition, in one embodiment, the sleeve piece 134 is fixed to the coupling section 122 by a fastener 160 such as a screw. The two extension portions 136 are respectively adjacent to two lateral edges of the sleeve piece 134 and extend from the bottom edge 132d. And the two extension portions 136 are bent towards the side corresponding to the inner surface 132a. When the swivel bracket 130 is closed to the seat 110, the extension portions 136 are bent towards the seat 110. Generally, the sleeve piece 134 is located at the center of the bottom edge 132d, and the two extension portions 136 extend from the bottom edge 132d and respectively located at two side of the sleeve piece 134.
As shown in FIG. 1 and FIG. 2, The two limiting bars 140 are respectively located in one of the two support portions 114 and are in the accommodation area 110a. The two limiting bars 140 are arranged coaxially and arranged in parallel to the shaft 120. The two limiting bars 140 are respectively provided corresponding to one of the two extension portions 136. Each of the limiting bars 140 is in a rotational path of the corresponding extension portion 136. When the swivel bracket 130 is flipped outward with respect to the seat 110, the extension portion 136 moves towards the limiting bar 136. As the swivel bracket 130 flipped outwards, the limit bar 140 can stop the extension portion 136 and limits the angle at which the swivel bracket 130 can be flipped out. In one or more embodiments, the hinge 100 is provided with only one limiting bar 140. At this time, the swivel bracket 130 is provided with one extension portion 136, that is, one extension 136 is located on one side of the sleeve piece 134.
As shown in FIGS. 1, 2, 4, and 5, the two support portions 114 are respectively provided with a slit 116. Each of the slits 116 communicates with the corresponding shaft hole 114a, and the two pivoting sections 124 are respectively provided with one of the two slits 116. In one or more embodiments, the slit 116 is in the upper plane 114b and perpendicular to the shaft hole 114a. The elastic arm 150 is in the slit 116 and is fixed to the seat 110. The elastic arm 150 presses against the pivoting section 124 of the shaft 120.
As shown in FIG. 4 and FIG. 5, In an example, the elastic arm includes a fixing section 152 and a pressing section 154. An included angle is defined between the fixing section 152 and the pressing section 154. The seat 110 is further provided with an insertion hole 116a and a fixation hole 118. The insertion hole 116a is located on the bottom of the slit 116, and the fixation hole 118 is provided at the fixation hole 114b and overlaps the slit 116. The fixing section 152 is configured to insert the insertion hole 116a to fix to the seat 110. The fixation hole 118 is configured for the fixation hole 160 to insert therein, and the fixation member 160 presses against the fixing section 152 or the pressing section 154, such that the elastic arm 150 is forced to press against the pivoting section 124 of the shaft 120. In an example, the fixation hole 118 is a screw hole while the fixation member is a bolt.
As shown in FIGS. 1, 4, and 5, a lateral side of the pivoting section 124 is provided with a mating plane 124a, and the mating plane is in parallel to an axial direction of the shaft 120 and arranged corresponding to the slit 116. The mating plane 124a of the two pivoting section 12 may be parallel to each other or may have an included angle defined therebetween. After the shaft 120 rotating, the elastic arm 150 presses against the mating plane 124a, to interfere with the shaft 120 to provide a positioning effect.
In this disclosure, the hinge 100 is provided with only one elastic arm 150. At this time, only one of the two support portions 114 has to be provided with a slit 116, and only one of the two pivoting sections 124 has to be provided with a mating plane 124a.
As shown in FIG. 4, FIG. 5 and FIG. 6, the extension portions 136 are bent towards the seat 110, and the sleeve piece 134 is bent towards the inner surface 132a of the mounting plate 132. Therefore, the angular limitation structure will not become a protruding structure on the outer surface 132b of the mounting plate 132, which facilitates the installation of the mounting plate 132 onto the door panel 220. Furthermore, the sleeve piece 134 and the extension portions 136 are structures extending from the mounting plate 132, which can simplify structure of the swivel bracket 130 and reduce the manufacturing cost.
As shown in FIG. 7 and FIG. 8, When the swivel bracket 130 is closed to the seat 110, the mounting plate 132 is accommodated in the accommodation area 110a. At this time, the door panel 220 fixed to the outer surface 132b of the mounting plate 132 abuts against the upper plane 114b. In an example, a distance from the limiting bar 140 to the upper plane 114b is greater than the thickness of the mounting plate 132. Therefore, the limiting bar 140 will not interfere with the mounting plate 132 in closed state, such that the mounting plate 132 is able to be fully received in the accommodation area 110a to have the door panel 220 abut against the setting upper plane 114b without tilting outwards.
As shown in FIG. 9, when the swivel bracket 130 is flipped outwards to a predetermined angle, for example, the angle between the mounting plate 132/door panel 220 and the upper plane 114b is 90 degrees, the elastic arm 150 abuts against the mating plane 124a to interfere with the shaft 120 to provide a positioning effect. At this time, the swivel bracket 130 and the door panel 220 are positioned at this predetermined angle.
As shown in FIG. 6 and FIG. 10, when the swivel bracket 130 is further flipped outwards to a maximum angle, for example, the angle between the mounting plate 132/door panel 220 and the upper plane 114b is 120 degrees. The spring arm 150 is detached from the mating plane 124a, and the extension portions 136 of the swivel bracket 130 abut against the limiting bar 140, such that the angle at which the swivel bracket 130/door panel 220 flips outwards is limited to this maximum angle.
The above angle values are for example only and is not intended to as shown in FIG. 11 and FIG. 12, in another embodiment of this disclosure, The two mating planes 124a are not parallel, and an angle is defined between the two mating planes 124a, such that the swivel bracket 130 and the door panel 220 are able to be positioned at two different predetermined angles.
As shown in FIG. 11, when the swivel bracket 130 is flipped outwards to a first predetermined angle, for example, the angle between the mounting plate 132/swivel bracket 130 and the upper plane 114b is 45 degrees, one of the two elastic arms 150 abuts against the corresponding mating plane 124a, and the other elastic arm 150 does not abut against the corresponding mating plane 124a. At this time, the swivel bracket 130 and the door panel 220 are positioned at this first predetermined angle.
As shown in FIG. 12, when the swivel bracket 130 is flipped outwards to a second predetermined angle, for example, the angle between the mounting plate 132/swivel bracket 130 and the upper plane 114b is 90 degrees, one of the two elastic arms 150 is detached from the corresponding mating plane 124a, and the other elastic arm 150 abuts against its corresponding mating plane 124a. At this time, the swivel bracket 130 and the door panel 220 are positioned at this second predetermined angle.
Through the above technical solution, the hinge 100 of this disclosure has the feature of simple structure and small volume, which is conducive to reducing the production cost. Meanwhile, this angular limitation structure is configured on the inner surface 132a of the mounting plate 132 or disposed in the accommodation areal 10a. Therefore, the angular limitation structure will not become a protruding structure on the outer surface 132b of the mounting plate 132, which facilitates the installation of the mounting plate 132 onto the door panel 220.
