The door body 2 further has a door front wall 21 and a door side wall 22, a door outer edge 23 is formed at an intersection position of the door front wall 21 and the door side wall 22, and a door inner edge 24 is formed at an intersection position of the door side wall 22 and the door rear wall, and when the door body 2 is in a closed state, that is, when the door body 2 covers the opening of the accommodating space, the door front wall 21 is disposed at a side of the door body 2 facing away from the box front wall 11. In the present utility model, the door front wall 21 is entirely planar, and the door front wall 21 is substantially parallel to the box front wall 11 when the door body 2 is in the closed state. It will be appreciated that the door front wall 21 may also be curved and be described with the door front wall 21 being planar for ease of description.

The case 1 is arranged beside the external environment member 100, and after the case 1 is put in place, the case side wall 12 faces the first side surface of the external environment member 100, i.e., the case side wall 12 is positioned opposite to the first side surface of the external environment member 100, and the case side wall 12 is substantially parallel to the first side surface of the external environment member 100.

In the closed state of the door body 2, the door side wall 22 also faces the first side of the external environment member 100, the door side wall 22 is opposite to the first side, the door side wall 22 is entirely planar in the present utility model, and the door side wall 22 is substantially parallel to the first side of the external environment member 100.

The refrigerating device may be a refrigerator, a freezer, a wine cabinet, etc., and the refrigerator is taken as an example.

In addition, the hinge assembly 3 is not only suitable for use in a refrigeration apparatus, but also suitable for use in other situations, such as a cabinet, a wardrobe, etc., and the present utility model is described with reference to the hinge assembly 3 being applied to the refrigerator 100.

Referring to fig. 1 to 5, the hinge assembly 3 includes a shaft structure 31 and a groove 32 engaged with the shaft structure 31; the shaft body assembly 31 is arranged on one of the box body 1 or the door body 2, and the groove body 32 is arranged on the other. In this embodiment, for convenience of description, the case where the groove 32 is provided on the door 2 is described as an example, and the shaft structure 31 is provided on the case 1 accordingly.

During the opening of the door body 2, the shaft body structure 31 slides in the groove body 32;

the shaft body structure 31 has a pair of shaft bodies, which are a first shaft body 311 and a second shaft body 312, respectively; the shaft body structure 31 further has a support plate, the first shaft body 311 and the second shaft body 312 are fixed on the support plate, and the support plate is fixed on the case 1.

When the door body 2 is closed, the first shaft body 311 is located closer to the door front wall 21 than the second shaft body 312, and the first shaft body 311 is located farther from the door side wall 22 than the second shaft body 312.

The slot 32 includes a first slot 321, and the first shaft 311 slides in the first slot 321 and has a motion component relatively close to the door sidewall 22 and relatively far from the door front wall 21 as the door body 2 is opened;

when the door body 2 is in the closed state, the first shaft body 311 and the second shaft body 312 are both positioned in the first groove 321, and the movement direction of the first shaft body 311 in the first groove 321 is approximately the same as the movement direction of the second shaft body 312 in the first groove 311 when the door body 2 is opened.

Here, the approximately same direction means that the movement direction of the first shaft body 311 in the first groove 321 and the movement direction of the second shaft body 312 in the first groove 311 may be changed in a small atmosphere, but the change range is small. The movement direction of the first shaft body 311 in the first groove 321 refers to the direction of the movement tendency of the first shaft body 311 in the first groove 321.

The above arrangement can move the door body in a direction away from the case 1 and the external environment member 100 at the initial stage of opening, thereby opening the space for the subsequent rotation and enabling the opening angle of the door body 2 to be larger.

It should be noted that, during the opening process of the door body 2, the position of the rotation center of the door body 2 relative to the rotation is varied; the center of rotation is a virtual axis.

The tank body 32 in this embodiment further has a second tank 322, where the second tank 322 is communicated with the first tank 321, and the extending direction of the second tank 322 is approximately the same as the extending direction of the first tank 321.

With the door body 2 opened, when the second shaft body 312 slides along the second groove 322, the first shaft body 311 slides in the first groove 321, and the movement direction of the first shaft body 311 in the first groove 321 is approximately the same as the movement direction of the second shaft body 312 in the second groove 322.

It will be appreciated that the arrangement of the above structure enables the door body 2 to have a component of movement that moves relatively away from the front wall 11 of the case and the door body 2 to have a component of movement that moves relatively away from the external environmental member 100 when the shaft structure 31 slides in the first slot 321 or the second slot 322 as the door body 2 is opened.

As shown in fig. 1 to 3, in the initial stage of opening the door body according to the present utility model, the shaft body structure 31 sequentially slides in the first groove 321 and the second groove 322, and during the sliding process, since the extending directions of the first groove 321 and the second groove 322 are approximately the same, the door body 2 has a motion component moving in a direction away from the case body 1 and away from the external environment member 100 when sliding in the first groove 321 and the second groove 322, so that the door body 2 has a larger moving space during the subsequent rotation.

As shown in fig. 3, in the present utility model, the shape of the first groove 321 is curved as a whole, the shape of the second groove 322 is curved as a whole, the curvature of the first groove 321 arches in a direction away from the door outer edge 23, and the curvature of the second groove 322 arches in a direction toward the door outer edge 23.

The first groove 321 is located farther from the door side wall 22 than the second groove 322, and the first groove 321 is located closer to the door front wall 21 than the second groove 322. The first groove 321 is integrally arc-shaped and arches towards a direction deviating from the door outer edge 23, so that the door body 2 can be better and more smoothly realized to approximately rotate in an initial stage of opening, and the door body 2 can be more conveniently and smoothly opened. The second groove 322 is arranged to arch in the opposite direction to the first groove 321, so that a foundation can be provided for the subsequent turning of the groove body, and meanwhile, the door body 2 can be more gentle in the process of moving away from the box body 1.

With the door body 2 opened, the shaft body structure 31 slides in the first groove 321, and the door outer edge 23 has a motion component moving close to the case 1 and then a motion component moving away from the case 1; and the door outer edge 23 has a motion component moving close to the external environment member 100 and then a motion component moving away from the external environment member 100.

In the initial stage of opening the door 2, the door 2 has a phase of approximately rotation in which the door outer edge 23 moves relatively in a direction approaching the case 1 while the door outer edge 23 moves relatively in a direction toward the external environmental member 100, but with further opening of the door 2, the door 2 as a whole moves away from the case 1 and away from the external environmental member 100, thus changing the moving direction of the door outer edge 23.

As shown in fig. 4, when the second shaft 312 slides in the second groove 322 along the groove 32 from the second position D2 to the third position D3 as the door 2 is opened, the door outer edge 23 has a movement component moving away from the case 1; and the door outer edge 23 has a motion component moving away from the external environment member 100 at the same time. When the second shaft 312 slides in the second groove 322, the door 2 moves in a direction away from the case 1 and away from the external environmental member 100, thereby driving the door outer edge 23 to move in the above direction.

As shown in fig. 3, the tank body 32 further has a third tank 323 and a fourth tank 324 communicating the third tank 323 with the second tank 322 in the present utility model; the first groove 321, the second groove 322, the third groove 323, and the fourth groove 324 are arranged in a direction sequentially approaching the door sidewall 22; the fourth groove 324 is engaged as a transition groove between the second groove 322 and the third groove 323.

The shaft structure 31 slides along the first groove 321, the second groove 322, the fourth groove 324, and the third groove 323 in this order as the door body 2 is opened.

As the second shaft body 312 slides in the first groove 321 and the second groove 321, the second shaft body 312 gradually approaches the door sidewall 22 and gradually moves away from the door front wall 21 as the door body 2 is opened;

as the second shaft body 312 slides in the third groove 323, the second shaft body 312 gradually approaches the door front wall 21 and gradually approaches the door side wall 22 as the door body 2 is opened.

The fourth slot 324 is generally arcuate and generally arches in a direction away from the door front wall 21. The second groove 322 and the third groove 323 are located on both sides of the fourth groove 324, respectively, and the turning of the extending direction of the tank body 32 is completed by the fourth groove 324.

As shown in fig. 5 to 6, as the door body 2 is opened, the second shaft body 312 slides in the fourth groove 324, the door outer edge 23 has a movement component moving close to the case front wall 11 and the door outer edge 23 has a movement component moving close to the external environment member 100.

The movement direction of the door outer rib 23 is away from the external environment 100 and away from the case 1 at the same time when the second shaft body 312 moves in the second groove 322. At this time, the movement locus of the door outer edge 23 is M1

The movement direction of the door outer edge 23 is close to the external environment 100 and close to the case 1 at the same time when the second shaft body 312 moves in the fourth groove 324.

In this embodiment the second slot 322 is immediately adjacent to the fourth slot 324, so that the door outer edge 23 actually has a movement process that approximates a reciprocating movement during opening of the door body. It should be noted that the motion trajectories of the two reciprocations are only approximately coincident, and there is a slight difference in practice.

As shown in fig. 7 to 9, as the door body 2 is opened, the second shaft body 312 slides in the third groove 323, and the door outer edge 23 has a movement component toward the case front wall 11; the door outer edge 23 has a movement component that moves in a direction approaching the external environment member 100 and then has a movement component that moves in a direction away from the external environment member 100.

The first shaft body 311 slides in the second groove 322 while the second shaft body 312 slides in the third groove 323 and the fourth groove 324.

As shown in fig. 7, when the door body 2 rotates the door outer edge 23 to be closest to the external environment 100; the second shaft body 312 slides in the fourth groove 324, and the first shaft body 311 slides in the second groove 322, and the door outer edge 23 is closest to the external environment 100 by 1.5mm in this embodiment.

The distance from the start end of the first groove 321 to the door front wall 21 is smaller than the distance from the end of the fourth groove 324 to the door front wall 21.

The second shaft body 312 is further away from the door front wall 21 when the door body 2 is at the maximum opening angle than when the door body 2 is in the closed state.

The ends of the first groove 321 and the beginning of the second groove 322 are both located at the D2 position, and the end D2 of the first groove 321 is located at the midpoint between the beginning D1 of the first groove 321 and the end D3 of the second groove 322.

With the door body 2 opened, when the second shaft body 312 slides in the second groove 322, a movement component of the door body 2 in the front-rear direction is greater than a movement component in the left-right direction.

The front-back direction is parallel to the opening direction of the accommodating space, the opening direction of the accommodating space is front, and the opening direction deviating from the accommodating space is back; the left-right direction is perpendicular to the front-rear direction on the horizontal plane, and is indicated by the drawing in this embodiment.

The above structure makes the door body 2 more prone to move away from the box body 1 during rotation, so that the door body 2 has a larger rotation opening space.

The angle between the extending direction of the first groove 321 and the left-right direction is 50-60 deg. in this embodiment.

The door body 2 further has a door rear wall and a door inner edge 24, the door rear wall intersecting the door side wall 22 at the door inner edge 24;

as shown in fig. 2, the door inner edge 24 moves in the left-right direction in a direction away from the tank side wall 12 as the door body 2 opens. I.e. the door inner edge 24 is always moved away from the external environment 100. The motion trail N of the inner edge of the door is shown in the figure.

As the second shaft body 312 slides in the third groove 323, the door inner rib 24 has a movement component moving away from the case front wall 11 and then has a movement component moving close to the case front wall 11;

as the second shaft 312 slides within the fourth groove 234, the door inner rib 24 has a movement component that moves closer to the box front wall 11 and then a movement component that moves away from the box front wall 11.

When the door body 2 is in the closed state, the distance from the second shaft body 312 to the door front wall 21 is greater than the distance from the first shaft body 311 to the door front wall 21; in this embodiment, the first shaft 312 is spaced from the door front wall 21 by a distance greater than 13mm.

When the door body 2 is in a closed state, the distance between the first shaft body 311 and the second shaft body 312 in the left-right direction is 8-12mm.

The distance between the first shaft body 311 and the second shaft body 312 is 13-20mm; the distance between the first shaft body 311 and the second shaft body 312 is a straight line distance between them.

When the door body is closed, an included angle between a connecting line of the first shaft body 311 and the second shaft body 312 and the left-right direction is 50-60 degrees.

In this embodiment, the maximum opening angle of the door body 2 after opening is 96 °. According to the utility model, through the arrangement of the structure, the gap between the box body 1 and the external environment 100 can be set to be 2mm, so that the embedded refrigerator is more attractive and the gap between the embedded refrigerator and an external environment piece is smaller. That is, the distance between the side wall 12 of the case 1 and the external environment member 100 is 2mm, when the gap between the case 1 and the external environment member 100 is greater than 2mm, the gap greatly affects the appearance, and when the gap between the case 1 and the external environment member 100 is less than 2mm, the installation of the refrigeration equipment is affected, thereby increasing the installation difficulty.

As will be described below with reference to an embodiment, when the door 2 is in the closed state, as shown in fig. 1-3, the first shaft body 311 and the second shaft body 312 are disposed in the first groove 321, and when the door 2 is opened to the first angle with the opening of the door 2, as shown in fig. 4, the second shaft body 312 moves along the first groove 321 to the end of the first groove 321, that is, the second position D2, and the first shaft body 311 moves along the first groove 321 from the first position D1 into the first groove 321. In this process, the door inner edge 24 moves toward the case front wall 21 and away from the external environmental member 100, and then moves toward the case front wall 21 and away from the external environmental member 100. The door body 2 is integrally provided with a movement in a direction away from the case 1 and away from the external environment 100.
