[0041] The embodiment of the utility model provides a door body structure, which can be applied to household appliances such as refrigerators, disinfection cabinets, dishwashers, etc. The application scenario type of the embodiment of the utility model does not limit the structure of the door body structure of the embodiment of the utility model.

[0042] The following is an example of the application of the door structure in a refrigerator. Figure 1 As shown, the refrigerator in the prior art includes a door body and a box body. Figure 1 The refrigerator in the illustrated embodiment is a double-door structure, that is, the refrigerator comprises a first door body 1 and a second door body 2. The door body is rotatably connected to the cabinet to open and close the storage cavity in the cabinet. Figure 1As shown, the first door body 1 is rotatably provided with a flip beam 31. When the first door body 1 closes the storage cavity, the flip beam 31 is sealed with the magnetic strips of the first door body 1 and the second door body 2, respectively, so that a relatively closed space is formed between the box body and the door body, thereby preventing the cold in the refrigerator from leaking. Figure 1 As shown, during the closing or opening process of the first door body 1, the flip beam 31 will flip relative to the first door body 1. When the first door body 1 is fully closed, the flip beam 31 is in an outward extension state, and when the first door body 1 is opened, the flip beam 31 is in an inward buckled state, which is equivalent to the flip beam 31 being folded relative to the first door body 1.

[0043] However, the existing flip beam 31 is easily flipped from a folded state substantially perpendicular to the first door body 1 to an extended state substantially parallel to the first door body 1 due to manual rotation or other external forces when the first door body 1 is opened. If this phenomenon occurs, when the second door body 2 is closed, the flip beam 31 will interfere with the left edge of the second door body 2 during the closing process of the first door body 1, causing the flip beam 31 to be stuck, the first door body 1 cannot be closed, and even causing the flip beam 31 to collide and be damaged with the second door body 2.

[0044] The embodiment of the utility model provides a door structure, which can be used for sealing and opening the refrigerator. The door structure in the embodiment of the utility model includes a first door 1, a second door 2 and a flip assembly 3. Figure 4 As shown, the flip assembly 3 is movably connected to the first surface 11 of the first door body 1, and the flip assembly 3 and the first door body 1 are in an extended and folded relative state. Figure 4 The figure shows the outward extension state of the flip assembly 3 relative to the first door body 1 in the embodiment of the utility model. Figure 6 The figure shows the folding state of the flip assembly 3 relative to the first door body in the embodiment of the utility model. Figure 4 and Figure 5 As shown, when the flip assembly 3 and the first door body 1 are in the extended state, the flip assembly 3 can be in surface contact with the second door body 2. It should be noted that surface contact means that when the flip assembly 3 is in contact with the second door body 2, the contact area of ​​the flip assembly 3 and the second door body 2 is the area of ​​a surface, rather than line contact or point contact.

[0045] Reference Figure 2 and Figure 3 As shown, Figure 2 It shows a schematic diagram of the structure of the first door body 1, the flip assembly 3 and the second door body 2 in the relevant embodiment. Figure 3 for Figure 2 A magnified view of the middle part. Figure 2As shown, when the first door body 1 is opened, the flip assembly 3 is easily flipped from the inward buckled state substantially perpendicular to the first door body 1 to the outward stretched state substantially parallel to the first door body 1 by manual rotation or other external forces. If this phenomenon occurs, when the second door body 2 is closed, the flip beam will interfere with the left edge of the second door body 2 during the closing process of the first door body 1. Figure 3 As shown, when the second door body 2 is closed, the second end face 332 of the outwardly extending flip beam 31 will collide with the second door body 2. Specifically, there is a certain angle α between the second end face 332 and the surface of the second door body 2. The second end face 332 cannot fit in contact with the surface of the second door body 2. The second end face 332 will contact the corner of the second door body 2 to cause a surface-to-point or surface-to-line contact. In other words, the existing flip beam 31 and the second door body 2 are in point contact or contact. The contact area of ​​this contact method is small. Under a certain collision pressure, the smaller the contact area, the greater the contact pressure. Therefore, after the flip beam 31 contacts and collides with the second door body 2 and gets stuck, it is easy to cause the risk of collision deformation or damage to the second door body or the flip beam.

[0046] Reference Figure 4 and Figure 5 As shown, Figure 4 It shows the structure diagram of the first door body 1, the flip assembly 3 and the second door body 2 in the embodiment of the utility model. Figure 5 for Figure 4 Enlarged view of part B in the middle. During the closing process of the first door body 1, the flip beam 31 will interfere with the left edge of the second door body 2. The embodiment of the utility model increases the contact area between the flip assembly 3 and the second door body 2 by setting the contact part between the flip assembly 3 and the second door body 2 to surface contact. Under the condition that the pressure of the collision between the flip assembly 3 and the second door body 2 is constant, it is helpful to reduce the pressure generated by the collision between the flip assembly 3 and the second door body 2, thereby reducing the risk of damage caused by the collision between the flip assembly 3 and the second door body 2, and also helps to reduce the noise generated by the collision between the flip assembly 3 and the second door body 2.

[0047] It should be noted that the embodiments of the present invention do not limit the manner in which the flip assembly 3 and the second door body 2 achieve surface contact. For example, the external contour structure of the flip assembly can be changed so that the flip assembly 3 and the second door body 2 meet the surface contact condition when in contact. Alternatively, the deformation generated when the flip assembly 3 and the second door body 2 are in contact can be changed by changing the material of the surface of the flip assembly 3, which can also achieve the effect of increasing the contact area. The manners in which the embodiments of the present invention achieve surface contact include but are not limited to the above-mentioned methods.

[0048] The embodiment of the utility model provides a door body structure, which includes a first door body, a second door body and a flip assembly, wherein the flip assembly is movably connected to the first surface of the first door body, and the flip assembly and the first door body have an extended and folded relative state, and when the flip assembly and the first door body are in the extended state, the flip assembly can be in surface contact with the second door body. The embodiment of the utility model increases the contact area of ​​the flip assembly in the contact state with the second door body by realizing surface contact between the flip assembly and the second door body when the flip assembly and the first door are in the extended state, and when the pressure of the collision between the flip assembly and the second door body is constant, the contact area is increased, which is conducive to reducing the pressure of the collision between the flip assembly and the second door body, thereby reducing the risk of deformation or damage of the collision between the flip assembly and the second door body, and also helps to reduce the noise generated by the collision between the flip assembly and the second door body.

[0049] It should be noted that Figure 8 The figure shows a deformation cloud diagram of the door structure in the relevant embodiment in the collision test. Fig. 9 The figure shows the deformation cloud diagram of the door structure in the embodiment of the utility model in the collision test. Figure 8 and Fig. 9 The collision speed in the embodiment is consistent. The color depth in the deformation cloud map indicates the degree of deformation. The darker the color, the greater the deformation. Figure 8 and Fig. 9 It can be seen that Figure 8 The maximum deformation in is 3.1305mm, while Fig. 9 The maximum deformation is 1.1612 mm. It can be seen that when the flip beam of the embodiment of the utility model is stuck by the second door body, the deformation of the flip beam is smaller than that of the prior art.

[0050] In some embodiments, Figure 4 As shown, the door structure also includes a guide seat 4, which is provided with a limiting groove 41. Generally speaking, the guide seat 4 is fixed to the box body in the refrigerator, and the limiting groove 41 on the guide seat 4 is set to an arc structure. When the first door body 1 and the second door body 2 are closed, the flip assembly 3 and the first door body 1 are in an extended state, and the flip assembly 3 is at least partially adapted to the limiting groove 41. In the process of the first door body 1 opening relative to the box body, the flip assembly 3 rotates relative to the first door body 1 under the restriction of the limiting groove to reduce the risk of collision between the flip assembly 3 and the second door body 2. In the process of the first door body 1 moving from the open state relative to the box body to the closed state, the flip assembly 3 can move under the restriction of the limiting groove so that the flip assembly can be more tightly fitted on the box body, reducing the risk of cold air leakage in the box body.

[0051] In some embodiments, in combination Figure 1 and Figure 5As shown, the flip assembly 3 includes a flip beam 31 and a guide block 33. The flip beam 31 and the first door body 1 are arranged around the length direction ( Figure 1 The turning beam 31 is rotatably connected to the first door body 1 (in the direction of the upper line shown); the turning shaft seat 32 is fixed at one end in the length direction of the first door body 1, and the turning beam 31 is rotatably connected to the turning shaft seat 32, so as to further realize the turning beam 31 and the first door body 1 can be rotatably connected. It should be noted that the embodiment of the utility model does not limit the number of the turning shaft seats 32. By increasing the number of the turning shaft seats 32, it is helpful to improve the stability of the connection between the turning beam 31 and the first door body 1. In the case where there are multiple turning shaft seats 32, the multiple turning shaft seats 32 are arranged at intervals in the length direction of the first door body 1.

[0052] The guide block 33 is disposed at the end of the flip beam 31. It should be noted that the end of the flip beam 31 represents the end of the flip beam 31 in the length direction ( Figure 1 That is to say, the guide block 33 can be set at the top end of the flip beam 31, and can also be set at the bottom end of the flip beam 31. Correspondingly, the guide seat 4 can also be set at the top end or the bottom end of the refrigerator body. The position of the guide seat 4 is set corresponding to the position of the guide block 33 to cooperate with each other.

[0053] The guide block 33 in the embodiment of the utility model is a structure protruding relative to the end of the flip beam 31, and the guide seat 4 is provided with a corresponding recessed limit groove. In other embodiments, a limit groove can be provided at the end of the flip beam 31, and a corresponding guide block can be provided on the guide seat 4, which can also realize the limit movement of the flip beam. In which, when the first door body 1 opens the box, the flip assembly 3 and the first door body 1 are in an extended state, such as Figure 4 As shown, the width direction of the flip beam 31 is parallel to the width direction X2 of the first door body 1, and one end of the flip beam 31 in the thickness direction Y1 can be attached to the second door body 2, wherein the attachment means that one end of the flip beam 31 in the thickness direction is in surface contact with the second door body 2.

[0054] In the embodiment of the present application, the width direction X2 of the first door body 1, the rotation axis of the first door body 1, and the thickness direction of the first door body 1 are perpendicular to each other.

[0055] Specifically, when the first door 1 of the refrigerator is opened, the flip beam 31 needs to remain in a folded state with the first door 1 under normal circumstances to avoid interference of the second door 2 with the rotation of the first door 1. If affected by manual rotation or other external forces, the flip beam 31 is likely to flip from a folded state substantially perpendicular to the first door 1 to an extended state substantially parallel to the first door 1. When the second door 2 is closed first, in the subsequent process of closing the first door 1, the flip beam 31 still in the extended state will interfere with the left edge of the second door 2, causing the flip beam 31 to be stuck, making it impossible to close the first door 1, or even causing the flip beam 31 to collide and be damaged with the second door 2.

[0056] In the embodiment of the utility model, by setting one end of the flip beam in the thickness direction as a surface that can fit with the second door body 2, when the second door body is closed first, if the flip beam is in an extended state relative to the first door body, even if the first door body 1 drives the flip beam to move toward the second door body 2, there will be surface contact between the flip beam and the second door body 2 instead of line contact or point contact, which changes the force condition of the flip beam 31 when colliding, and reduces the deformation and damage degree of the flip beam after the collision with the second door body.

[0057] In some embodiments, Figure 4 and Figure 5 As shown, the flip beam 31 is in the thickness direction ( Figure 4 In the Y1 direction as shown, it has a relative first end face 331 and a second end face 332. When the flip beam 31 is in an extended state relative to the first door body 1, the first end face 331 is close to the first surface 11 of the first door body 1 relative to the second end face 332, that is, the second end face 332 is close to the second door body 2, and the second end face 332 is used for surface contact with the second door body 2.

[0058] For some examples, see Figure 5 , along the direction away from the rotating shaft seat 32, the distance between the first end face 331 and the second end face 332 in the thickness direction of the flip beam 31 gradually increases. In other words, within the extension length range of the first end face 331 and the second end face 332, the thickness of the flip beam 31 gradually increases. In this way, it is beneficial to adapt to the first door body 1 and the second door body 2 in the thickness change of the flip beam 31. Figure 5 The angle in the shown state.

[0059] In some embodiments, the angle θ between the second end surface 332 and the reference surface is greater than zero, wherein the reference surface is perpendicular to the thickness direction of the first door body 1. For example, when the outer surface of the first door body 1 is a flat surface, the reference surface is parallel to the outer surface of the first door body 1. For another example, when the first surface 11 is a flat surface, the reference surface is parallel to the first surface 11. For another example, the width direction ( Figure 4In other words, the second end surface 332 is inclined relative to the reference surface, rather than being parallel to it. Figure 3 As shown, the second end surface 332 of the flip beam 31 in the prior art is parallel to the width direction of the first door body 1 in the extended state. Therefore, when the flip beam is in contact with the second door body 2, there is an angle α between the second end surface 332 and the second door body 2. Figure 5 As shown, the embodiment of the utility model reduces the angle between the second end face 332 and the second door body 2 in the contact state by tilting the second end face 332 with the reference plane, increases the contact area between the second end face 332 and the second door body 2, thereby achieving surface contact between the second end face 332 and the second door body 2, so as to further reduce the risk of collision deformation or damage of the flip beam with the second door body.

[0060] In some embodiments, Figure 5 As shown, the extension direction of the second end surface 332 ( Figure 5 X1 direction) and the width direction of the first door body 1 ( Figure 5 The angle θ between the extension direction of the second end surface 332 and the width direction of the first door body 1 is set to a set value, which is related to the thickness of the flip beam 31 and the relative position of the flip beam 31 and the second door body 2. Specifically, the setting of the angle θ between the extension direction of the second end surface 332 and the width direction of the first door body 1 in the embodiment of the utility model is related to the contact position between the flip beam 31 and the second door body 2, and the contact position is affected by the thickness of the flip beam 31 ( Figure 4 The angle θ is related to the size of the flip beam 31 in the Y1 direction shown in the figure, and the position where the flip beam 31 is connected to the first door body 1. For example, when other parameters remain unchanged, the greater the thickness of the flip beam 31, the greater the angle θ, and the smaller the thickness of the flip beam 31, the smaller the angle θ. The embodiment of the utility model sets different angles according to flip beam structures of different sizes, so that the second end face can better fit the second door body, so as to meet the production and use requirements of products of different specifications.

[0061] In some embodiments, Figure 4 and Figure 5 As shown, in the outward state of the flip assembly 3 and the first door body 1, the first end surface 331 is parallel to the reference surface, that is, the first end surface is parallel to the width direction of the first door body 1 ( Figure 3 The embodiment of the utility model makes the first end face 331 parallel to the reference plane. In the extended state, the first end face 331 is limited by the first door body 1, and the first end face 331 can maintain a fitted position with the first door body 1, which is conducive to reducing the risk of the first door body 1 colliding with the first end face 331 and damaging it.

[0062] In some embodiments, Figure 6 and Figure 7As shown, in the folded state of the flip assembly 3 and the first door body 1, which is equivalent to the inward buckled state, the minimum distance L1 between the second end face 332 and the shaft seat 32 is greater than zero. In other words, the second end face 332 cannot contact the shaft seat 32. The embodiment of the utility model does not limit the angular relationship between the shaft seat 32 and the first surface 11, that is, no matter what relationship the shaft seat 32 maintains with the first surface 11, as long as the second end face 332 does not contact the shaft seat 32 in the folded state. The embodiment of the utility model makes the distance between the second end face 332 and the shaft seat 32 greater than zero, so that when the flip beam is in a folded state substantially perpendicular to the first door body, the second end face 332 of the flip beam 31 will not interfere with the shaft seat 32, and its structure is simple and reasonable, and easy to process and manufacture.

[0063] In some embodiments, the second end face of the flip assembly in the expanded state is close to the second door body, and the door body structure also includes a flexible buffer. The flexible buffer refers to a material with a certain elasticity. The flexible buffer can be deformed under the action of an external force and can restore the deformation after the external force disappears. The flexible buffer can be set on the second end face of the flip assembly. In the extended state of the flip assembly, the flexible buffer can contact the second door body. The flexible buffer is locally deformed at the contact position, and the deformed flexible buffer can be wrapped around the surface of the second door body, so that the flexible buffer and the second door body are in surface contact, and the deformed flexible buffer can absorb the impact force between the flip beam and the second door body, thereby reducing the risk of collision damage between the flip beam and the second door body.

[0064] In some embodiments, the flexible buffer is configured as one or more of sponge, silica gel, and foam plastic. The flexible buffer in the embodiment of the utility model is configured as a material with a certain elastic deformation ability, and the flexible buffer can absorb a certain impact and play a buffering role, thereby reducing the risk of impact damage.

[0065] The embodiment of the utility model also provides a refrigerator, which includes a door structure and a box body according to any of the above embodiments. A storage cavity is provided inside the box body; the first door body is rotatably connected to the box body to open and close part of the storage cavity, and when the first door body closes the box body, the first surface is close to the box body; the second door body is rotatably connected to the box body to open and close another part of the storage cavity. The embodiment of the utility model increases the contact area of ​​the flip assembly in the contact state with the second door body by realizing the surface contact between the flip assembly and the second door body when the flip assembly is in the extended state outside the first door body. When the pressure of the flip assembly colliding with the second door body is constant, the contact area is increased, which is conducive to reducing the pressure of the flip assembly colliding with the second door body, thereby reducing the risk of deformation or damage of the flip assembly colliding with the second door body, and also helps to reduce the noise generated by the collision between the flip assembly and the second door body, thereby improving the product quality of the refrigerator.
