Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 7, in the embodiment of the utility model, an embedded switch door hinge comprises a cabinet body hinged plate 1, a door body mounting plate 2 and a cabinet body mounting plate 5, wherein the cabinet body mounting plate 5 is vertically attached and fixed on the top or bottom edge side of a cabinet body door cavity, the door body mounting plate 2 is horizontally fixed on a front panel of the cabinet body hinged plate 1, the door body mounting plate 2 is integrally embedded and fixedly mounted on the top or bottom of a door body, the cabinet body hinged plate 1 and the door body mounting plate 2 are mutually closely adjacent and horizontally parallel, the panels on the opposite surfaces of the cabinet body hinged plate 1 and the door body mounting plate 2 are mutually clamped and connected in a sliding manner through a track frame 3 and a luxo triangular block 4, the luxo triangular block 4 is sleeved in an inner ring wall of the track frame 3, the unilateral side wall of the luxo triangular block 4 is connected with the unilateral inner wall of the track frame 3 in a sliding manner, and in the process that the cabinet body hinged plate 1 is opened from one side of the door body mounting plate 2, the reuleaux triangle block 4 rolls in the track frame 3, the gravity center changes and the door body mounting plate 2 is driven in the horizontal direction to move towards the direction far away from the door plate on the hinged side of the cabinet body.
The track frame 3 is fixed on the top panel of the hinge plate 1 of the refrigerator body, the top surface of the reuleaux triangle 4 is fixed on the bottom surface of the door body mounting plate 2, the reuleaux triangle 4 rotates along with the door body mounting plate 2 in the rotation process of the door body mounting plate 2, the rotation process of the reuleaux triangle 4 is dragged by the motion trail of the reuleaux triangle 4, the reuleaux triangle 4 rotates in the fixed track frame 3, the gravity center of the reuleaux triangle 4 deviates towards the opposite direction of the door plate at the hinge side of the refrigerator body, in the moving process, the gravity center of the reuleaux triangle 4 moves under the action of the track frame 3, the turning vertical edge of the door body mounted on the door body mounting plate 2 can retract inwards, thereby the door body cannot bulge out for too long distance and cannot impact the inner wall of the external refrigerator body embedded in the refrigerator, in addition, the track frame 3 can also be fixedly mounted on the bottom surface of the door body mounting plate 2, as long as the reuleaux triangle block 4 is ensured to be clamped in the track frame 3 to roll.
The depth range of the vertical clamping of the track frame 3 and the Leluo triangular block 4 is as follows: 5mm ~ 10mm, the minimum degree of depth that the reuleaux triangle-shaped piece 4 inserted track frame 3 herein sets up mainly guarantees that reuleaux triangle-shaped piece 4 and track frame 3 can not the dropout, the degree of depth that the reuleaux triangle-shaped piece 4 keeps enough and track frame 3 interlock under guaranteeing enough anti-deformation intensity, guarantee that reuleaux triangle-shaped piece 4 can not directly drop out and overturn when rolling in track frame 3, it is unlikely to the excessive thickness here to set up the height of the vertical direction of cabinet body articulated slab 1 and the articulated department of door body mounting panel 2 mainly to consider, guarantee the simplicity and the reduction cost of manufacture of cabinet body articulated slab 1 and the installation of door body mounting panel 2.
The intersection of the adjacent inner walls of the track frame 3 is arc-shaped, so that the edges of the reuleaux triangular block 4 can slide more smoothly when bypassing the adjacent inner walls of the track frame 3, and the smoothness of door opening action is ensured.
The cabinet body articulated slab 1 with be equipped with between the door body mounting panel 2 and be used for door body mounting panel 2 to restore to the spring of closed state by the open mode, the spring that sets up can be at door body mounting panel 2 opening in-process deformation tensile storage elastic potential energy, after loosening external force, the spring contracts back and pulls door body mounting panel 2 and resume to initial closed state again.
The cabinet body articulated slab 1 with be equipped with the spacing subassembly that is used for restricting door body mounting panel 2 and opens the angle between the door body mounting panel 2, spacing subassembly can be limiting plate or other stop gear, and main assurance door body mounting panel 2 is opening the in-process, and the door body with door body mounting panel 2 fixed mounting can not bump into outside embedded outer tank wall on, reduces the scratch on door body surface.
The working principle of the utility model is as follows: the motion condition of the hinged edge of the door body mounting plate 2 is analyzed by selecting a point M of the door body mounting plate 2, which is close to the inner wall of the outer box, as an analysis object, when the door body mounting plate 2 is closed on the cabinet body hinged plate 1, at this time, the gravity center position of the reuleaux triangle block 4 is a point G, the point M makes a circular motion by taking the G as a circle center, the expected rotation track is an arc line J, when the door body mounting plate 2 is opened, the reuleaux triangle block 4 rotates anticlockwise, the gravity center of the reuleaux triangle block 4 moves to a point E position, the motion track of the point M by taking the E as a circle center is an arc line F, because the gravity center of the reuleaux triangle block 4 actually is also in a moving state in the rotation process of the door body mounting plate 2, the actual motion track of the point M should be a process that the arc line J leans to the arc line F, namely, a path similar to the arc line H, if the G is a fixed axis, the maximum width extending out of the point M is a line segment AB, under the condition that the center of gravity of the Rollo triangular block 4 rotates to move, the maximum width of the point M extending outwards is a line segment CD, the outward extending amount of the point M is reduced, and an embedding gap between a refrigerator and an external box body can be smaller and more fit.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
