Detailed Description

The utility model relates to a double-track embedded hinge and a refrigerator, which are further described with reference to fig. 1-3, wherein the refrigerator comprises a box body and a door body hinged on the box body, the hinge is a double-track embedded hinge and comprises a support 3 fixed on the box body and a guide slot matched with the support 3 and arranged on the end face of a door body 6, one end of the support 3, which is close to the door body 6, is provided with a hinge shaft, the hinge shaft comprises a first hinge shaft 1 and a second hinge shaft 2, and the first hinge shaft 1 is positioned outside the second hinge shaft 2; the guide slots include a first guide slot 4 and a second guide slot 5, the first hinge shaft 1 is inserted into the first guide slot 4, and the second hinge shaft 2 is inserted into the second guide slot 5. The diameters and the lengths of the first hinge shaft 1 and the second hinge shaft 2 are the same, the widths and the depths of the first guide slot 4 and the second guide slot 5 are the same, and the lengths and the diameters of the first hinge shaft and the second hinge shaft are matched with the guide slot where the first hinge shaft and the second hinge shaft are positioned. The second guide groove 5 is in a herringbone structure, the first guide groove 4 is in an arc-shaped structure from left to right, a reverse folding part is formed at the rightmost end, and the herringbone head faces the reverse folding part. The door body 6 is provided with a notch at the position corresponding to the support, and the guide groove is arranged on the bottom end face of the notch. The rear section of the support 3 is fixed on the end face of the refrigerator body 7.

The process of designing the embedded hinge according to the present utility model will be described in detail with reference to fig. 4, and the steps are as follows:

step 1: determining the position of the hinge shaft (namely determining the vertical distance a from the axis of the hinge shaft to the box body and the vertical distance b from the axis of the hinge shaft to the side plate of the box body), and determining the thickness d of the door body (the thickness of the door body of the refrigerator comprises the thickness of a door seal and the distance between the front end surface of the door body and the box body);

step 2: determining refrigerator door motion

When the refrigerator door body is in a closed state by taking a top view of the refrigerator as a reference, two points on the side face of the refrigerator door are defined, a point close to the refrigerator body 6 is a point A, a point far away from the refrigerator body 6 is a point B, a point on the side face of the cabinet body corresponding to the refrigerator is a point A1, and a point on the side face of the cabinet body corresponding to the point B is a point B1. In the process of opening the door of the refrigerator from the closed state to the 90-degree state, the point B moves inwards along the direction of the straight line B1A1, and the point A moves inwards along the line of the side of the refrigerator body 7. The included angle between the side surface of the refrigerator door body 6 and the side surface of the refrigerator is positioned as a door opening angle theta.

Step 3: determining motion trail equation of hinge shaft in process of closing refrigerator door 7 to 90 degrees of door opening

The vertical distance between the center of the hinge shaft and the refrigerator body 6 is known as a, and the vertical distance between the center of the hinge shaft and the refrigerator body is known as b; the motion trail equation calculation process in the door opening process is as follows:

taking the point B of the refrigerator door as a coordinate origin, taking a straight line BA as a Y axis and taking a straight line vertical to the BA as an X axis; the position of the central axis of the hinge shaft is an O point; the straight line perpendicular to the front end surface of the refrigerator body 7 is drawn from the point O, the drop foot is the point F, the straight line perpendicular to the side surface of the refrigerator body is drawn from the point O, the drop foot is the point G, the intersection point of the FO and the Y axis is J, and the intersection point of the GO and the Y axis is M; a straight line perpendicular to the Y axis is drawn from the O point, and the drop foot is I;

then:

a＝FO＝A1G＝FJ+JO

b＝GO＝A1F＝GM+MO

solving the coordinates (x, y) of the O point in a motion coordinate system by utilizing a trigonometric function relation, wherein,

x=b×cos θ d×cos θ×sin θ ten sin θ

The coordinates (x, y) of the O point in the motion coordinate system are the motion track equation of the hinge shaft in the process of closing the refrigerator door body to 90 degrees of door opening;

step 4: and drawing the track of the hinge shaft corresponding to the guide slot according to the equation.
