Pressing part 20

The pressing portion 20 includes a pressing member 21 and an abutting member 25, as shown in fig. 2 a. The pressing piece 21 is movably connected to the door body connecting portion 10, and the pressing piece 21 has a closed state and an open state. A limit structure may be disposed in the door body connecting portion 10 or the handle portion 30 to limit a movement range of the pressing member 21, and one limit position of the movement of the pressing member 21 is a closed state, as shown in fig. 3a, and the other limit position of the movement is an open state, as shown in fig. 4 a. The moving direction from the closed state to the open state may be upward movement, which is consistent with the direction of opening the door. Taking fig. 3a and 4a as an example, the closed state is a position where the pressing member 21 falls to the lowest point, and the open state is a position where the pressing member 21 moves to the highest point, where the lower surface of the pressing member 21 is flush with the lower surface of the lower cover.

The closed state of the pressing member 21 is also a state in which the door 300 is closed without being subjected to an external force, and when the pressing member 21 is in the open state, the user may be in a state in which the pressing member 21 is completely pressed to the stroke end thereof.

In the process of switching from the closed state to the open state, the pressing member 21 has a force that drives the abutting member 25 to move towards the bearing wall 2111, the abutting member 25 has a tendency to move towards the bearing wall 2111, the abutting member 25 is relatively far away from the door body connecting portion 10, and the distance between the bearing wall 2111 and the door body connecting portion 10 increases.

The holding member 25 has a tendency to move toward the direction of the bearing wall 2111, may be the holding member 25 moves toward the bearing wall 2111, or may have a force moving toward the direction of the bearing wall 2111, but is held by the bearing wall 2111 and cannot move, at this time, even if the holding member 25 does not move, because the door body connecting portion 10 is away from the holding member 25, that is, the holding member 25 is relatively away from the door body connecting portion 10.

Specifically, the downward movement of the holding member 25 relative to the door body connecting portion 10 includes two embodiments, and in one embodiment, when the door body 300 is closed, the holding member 25 does not contact with the bearing wall 2111, or a certain distance exists between the holding member 25 and the bearing wall 2111. When the pressing member 21 is switched from the closed state to the open state, the abutting member 25 moves toward the box connecting portion until abutting against the supporting wall 2111.

In another embodiment, when the door 300 is closed, the holder 25 contacts the bearing wall 2111, but the force of the holder 25 pressing the bearing wall 2111 is not generated. In the process of switching the pressing member 21 from the closed state to the open state, the abutting member 25 is always stationary relative to the bearing wall 2111, but tends to move in the direction of the bearing wall 2111 by applying a downward force to the bearing wall 2111.

After the abutting member 25 abuts against the bearing wall 2111, the bearing wall 2111 applies a reaction force to the abutting member 25, and the reaction force of the bearing wall 2111 to the abutting member 25 is the same as the opening direction of the door 300, that is, the door connecting portion 10 is pushed to move away from the bearing wall 2111. The door body 300 is assisted by the box body 200, so that the door body 300 can be opened more easily.

In this embodiment, the pressing piece 21 may extend from the position of the left door body connecting portion 10 to the position of the right door body connecting portion 10, so that the pressing piece 21 can be pressed at any position between the left door body connecting portion 10 and the right door body connecting portion 10, and the movement of the abutting piece 25 is realized.

The pressing portion 20 further includes an elastic member 24, one end of the elastic member 24 abuts against the door connecting portion 10, and the other end of the elastic member 24 abuts against the abutting member 25, and the elastic member 24 always has a tendency of driving the abutting member 25 to move in a direction away from the bearing wall 2111. The resilient member 24 may be provided as a spring,

furthermore, the pressing portion 20 further includes a lever 22, one end of the lever 22 abuts against the pressing member 21, the other end of the lever abuts against the supporting member 25, and a rotating shaft 221 is disposed between two ends of the lever 22, so that the pressing member 21 and the supporting member 25 move in opposite directions. Thus, when the door is opened, the door 300 is far away from the box 200, and the abutting piece 25 needs to move towards the box 200, that is, after the lever piece 22 is arranged, the moving direction of the pressing piece 21 is the same as the moving direction of the door 300 when the door is opened, so that the user does not need to switch the direction of the force, and the door opening assisting force can be formed by the operation like normally lifting the door upwards.

In combination with the door 300 of the present embodiment disposed above the box 200, the abutting piece 25 is disposed above the receiving portion, and during the process of switching the closed state to the open state, the moving direction of the pressing piece 21 is the same as the moving direction of the door 300. Thus, while the door 300 is pulled up, the upward force is applied and the load wall 2111 is pressed downward, so that the load wall 2111 applies an upward assisting force. In the process of switching between the closed state and the open state, the holder 25 moves vertically upward or vertically downward. The bearing wall 2111 is horizontally arranged, so that the movement direction of the holding piece 25 is relatively vertical to the bearing wall 2111, a component force in the horizontal direction is not generated, and a transverse friction force is avoided. Therefore, when a user pulls up the handle assembly 100 in front of the refrigerator 1000, the pressing member 21 is pulled upwards, the lever member 22 rotates to drive the abutting member 25 to move vertically downwards away from the door body connecting portion 10, the abutting member 25 is vertically abutted against the bearing wall 2111, and the friction between the abutting member 25 and the bearing wall 2111 is very small or even very small, so that the friction is reduced compared with the prior art, the labor is saved, and the bearing wall 2111 cannot be scraped by transverse movement in all directions.

In the present embodiment, the lower cover is provided with a slot 31, as shown in fig. 3a or 4a, the pressing member 21 includes a holding wall 211 and a pressing handle 212, and the pressing handle 212 extends to the lower side of the slot 31 through the slot 31, that is, the pressing member 21 is exposed outside the handle portion 30. The supporting wall 211 is disposed above the slot 31, and the width of the supporting wall 211 is larger than that of the slot 31, so that the pressing member 21 does not fall out of the slot 31. The pressing piece 21 is arranged below the lower cover and extends downwards, and the pressing piece 21 can be conveniently held to move upwards when the door is opened, and the moving direction of the abutting piece 25 is opposite.

In addition, the bearing walls 2111 and the abutting parts can be arranged in two groups in parallel at the left and right, and the pressing piece 21 simultaneously drives the abutting pieces 25 at the left and right sides to abut against the bearing walls 2111 at the two sides, so that the effect of more stable and balanced stress is achieved.

One end of the lever member 22 facing the pressing member 21 is set to be an arc-shaped surface, and one side of the abutting wall 211 facing the lever member 22 is set to be an arc-shaped surface, as shown in fig. 2a, 3a and 4a, one end of the lever member 22 facing the pressing member 21 makes arc motion around the rotating shaft 221, so that the abutting wall 211 contacting the lever member 22 is also set to be an arc-shaped surface, the abutting wall 211 is more smoothly contacted with the lever member 22, and stress concentration is avoided.

Further, a side of the abutting member 25 facing the lever member 22 is configured as a plane, and during the process of switching the closed state to the open state, the lever member 22 slides on the surface of the abutting member 25, as shown in fig. 3a to 4 a.

The distance from the contact position of the pressing piece 21 and the lever piece 22 to the rotating shaft 221 is longer than the distance from the contact position of the abutting piece 25 and the lever piece 22 to the rotating shaft 221, so that the pressing piece 21 moves for a longer distance, the abutting piece 25 can move for a shorter length, and the effect of saving labor for opening the door is realized through the lever principle.

The door opening process is explained below:

when the components are in the initial state, that is, the door 300 is closed and no force is applied to the pressing member 21, the abutting member 25 may or may not contact the bearing wall 2111;

when the door is opened, a user holds the handle part 30, and since the pressing piece 21 extends from left to right, the user inevitably holds the pressing piece 21, and since the pressing piece 21 extends downwards below the lower cover, when the user applies an upward force to the handle assembly 100, the user inevitably applies an upward force to the pressing piece 21 at the same time, so that in the process of opening the door, the user does not need to deliberately press the pressing piece 21, the upward force is naturally applied to the pressing piece 21, and then the supporting piece 25 moves downwards, so that the supporting piece 25 is supported against the bearing wall 2111, and the door opening assisting force is formed, and the user can conveniently open the door;

after the user releases his/her hand by closing the door 300, the pressing member 21 is restored by the elastic force of the elastic member 24 and the gravity of the pressing member 21 itself, and the abutting member 25 is restored to the initial state by the elastic member 24.

Compared with the prior art, the embodiment has the following beneficial effects:

under the abutting action of the abutting piece 25 and the bearing wall 2111, the bearing wall 2111 can reversely apply upward force to the door body 300, so that the door opening assisting effect is realized, and the door body 300 can be smoothly opened; when the door 300 is driven to be opened by the reaction force, the door does not slide on the bearing wall 2111, friction force cannot be generated, and only upward supporting force is generated, so that the friction force is avoided, the door opening resistance is reduced, the surface of the refrigeration equipment or the handle assembly 100 is not abraded, the appearance of the refrigeration equipment is protected, and the use experience of a user is improved.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
