[0048] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0049] The embodiment of the present application provides a door body locking assembly and a refrigerator to solve the problem that when the door hook of the existing refrigerator door body engages with the hinge hook, the door hook is easily worn or deformed, thereby affecting the tightening force between the door hook and the hinge, resulting in cold air leakage or abnormal noise of the door body. The following will be described in conjunction with the accompanying drawings.

[0050] The door body 6 locking assembly provided by the embodiment of the present application is applied to a refrigerator. Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 . Figure 1 This is a schematic structural diagram of the door body locking assembly provided by the embodiment of the present application when the door body is in a state of closing the box body. Figure 3 This is a schematic structural diagram of the door body locking assembly provided by the embodiment of the present application when the door body is in a state of opening the box body by 15°. Figure 4 This is a schematic structural diagram of the door body locking assembly provided by the embodiment of the present application when the door body is in a state of opening the box body by 90°. Figure 5The structural schematic diagram of the door locking assembly provided in the embodiment of the present application when the door is in the state of opening the box by 120°, the refrigerator includes a box and a door 6, the door 6 includes a connecting end 61, the connecting end 61 is rotatably connected to the box, and the door 6 locking assembly includes a hinge 1 and a second clamping portion 2. One end of the hinge 1 is fixedly arranged on the box, and the other end is rotatably connected to the connecting end 61 of the door 6; a first clamping portion 11 is provided at one end of the hinge 1 close to the door 6; the second clamping portion 2 is arranged on the door 6, the second clamping portion 2 rotates with the door 6, and the first clamping portion 11 is at least partially located on the rotation path of the second clamping portion 2; wherein, one of the first clamping portion 11 and the second clamping portion 2 is elastic, when the door 6 closes the box, the first clamping portion 11 is located on the side of the second clamping portion 2 away from the box, and is clamped with the second clamping portion 2; when the door 6 rotates to open the box, one of the first clamping portion 11 and the second clamping portion 2 is compressed and contracted, and is separated from the other. Among them, the first clamping part 11 is at least partially located on the rotation path of the second clamping part 2, that is, on the movement trajectory of the second clamping part 2 when following the rotation of the door body 6, and there is at least one position where the first clamping part 11 and the second clamping part 2 interfere with each other.

[0051] In the locking assembly of the door body 6 provided in the embodiment of the present application, the first clamping part 11 is at least partially located on the rotation path of the second clamping part 2. Therefore, when the door body 6 closes the box, the second clamping part 2 follows the door body 6 to rotate to the side of the first clamping part 11 close to the box, and is elastically clamped with the first clamping part 11. The second clamping part 2 is limited on the rotation path of the second clamping part 2 by the first clamping part 11, thereby avoiding rebound when the door body 6 abuts against the box, thereby ensuring the tightness of the connection between the door body 6 and the box. At the same time, since one of the first clamping part 11 and the second clamping part 2 is elastic, when the door body 6 rotates to open the box, the elastic first clamping part 11 or the second clamping part 2 will be compressed, and then separated from the other of the two, completing the unlocking, so that the door body 6 continues to rotate to open the box. That is, the first clamping part 11 and the second clamping part 2 are elastically clamped together, which has a larger elastic deformation margin, so that the first clamping part 11 and the second clamping part 2 are not easy to wear, thereby extending the service life of the equipment. At the same time, the tightness of the connection between the door body 6 and the box body is ensured to avoid cold air leakage or abnormal noise from the door body 6.

[0052] Optionally, the first clamping portion 11 and the second clamping portion 2 may both be in a strip or rod shape.

[0053] Optionally, a rotating hole may be provided on the door body 6, a rotating rod may be provided on the hinge 1, and the hinge 1 is rotatably connected in the rotating hole via the rotating rod.

[0054] Optionally, see Figure 2 , Figure 2 for Figure 1In the partial enlarged view of point A in the middle, a first protrusion 111 is correspondingly provided at one end of the first clamping portion 11 close to the second clamping portion 2, and the first protrusion 111 extends from the first clamping portion 11 to the side close to the box body; a second protrusion 21 is provided at one end of the second clamping portion 2 close to the first clamping portion 11, and the second protrusion 21 extends from the second clamping portion 2 to the side away from the box body; when the door body 6 closes the box body, the first protrusion 111 is located on the side of the second protrusion 21 away from the connecting end 61, and abuts against the second protrusion 21.

[0055] By means of the first protrusion 111 and the second protrusion 21 being arranged opposite to each other, and when the door body 6 closes the box body, the first protrusion 111 is located on the side of the second protrusion 21 away from the connecting end 61, when the first clamping part 11 and the second clamping part 2 are subjected to force and need to be separated from each other, the first protrusion 111 limits the second protrusion 21 in the direction of the second protrusion 21 away from the first clamping part 11, thereby increasing the external force required for the second clamping part 2 and the first clamping part 11 to separate, preventing the refrigerator door body 6 from opening the box body upon being subjected to a slight collision or pulling force, thereby further ensuring the tightness of the seal between the refrigerator door body 6 and the box body.

[0056] The shapes of the first protrusion 111 and the second protrusion 21 are not further limited here, for example, they can both be hemispherical, block-shaped, or ellipsoidal, etc. Preferably, the surfaces of the first protrusion 111 and the second protrusion 21 can both be curved surfaces that arch toward each other, so as to achieve the abutment effect while facilitating the separation of the first protrusion 111 and the second protrusion 21, preventing the presence of areas with large curvature changes on the surfaces of the first protrusion 111 and the second protrusion 21, which causes the first protrusion 111 and the second protrusion 21 to jam during the separation process, reduce the wear between the first protrusion 111 and the second protrusion 21, and extend the service life.

[0057] Optionally, see Figure 7 , Figure 7 The top view of the door body of the refrigerator provided in the embodiment of the present application, the first limiting portion 112 is provided on the side of the hinge 1 away from the box body; the door body 6 locking assembly also includes a second limiting portion 3, the second limiting portion 3 is arranged on the door body 6, and is located at the end of the first limiting portion 112 away from the box body; wherein, when the door body 6 is rotated to a preset angle, the first limiting portion 112 and the second limiting portion 3 are in limiting contact.

[0058] Specifically, the hinge 1 is correspondingly provided with a recess to accommodate the second limiting portion 3 when the door body 6 closes the box body. That is, the first limiting portion 112 is located at one end of the recess away from the box body and on the side of the recess close to the connecting end 61. Thus, when the door body 6 closes the box body, the second limiting portion 3 fits or is spaced from the recess. When the door body 6 rotates to a preset angle, the first limiting portion 112 and the second limiting portion 3 are in limiting abutment to limit the second limiting portion 3 from continuing to rotate away from the box body, and further limit the door body 6 from continuing to rotate away from the box body, so that the door body 6 can only be opened up to the preset angle at most, preventing the door body 6 from opening too large an angle and hitting the box body or other objects.

[0059] No further limitation is made on the preset angle here. In some examples, it can be 90°, 100°, 110°, 120°, 130°, etc. Nor is there any further limitation on the shapes of the first limiting portion 112 and the second limiting portion 3, which can be selected according to specific circumstances, such as block-shaped, spherical, etc.

[0060] Furthermore, the first limiting portion 112 and / or the second limiting portion 3 can be made of shock-absorbing materials, such as rubber, plastic, or foam, etc. As a specific implementation manner, the first limiting portion 112 is made of a shock-absorbing material; as another specific implementation manner, the second limiting portion 3 is made of a shock-absorbing material; as another specific implementation manner, both the first limiting portion 112 and the second limiting portion 3 are made of shock-absorbing materials;

[0061] Optionally, both the first clamping portion 11 and the second clamping portion 2 extend along the width direction of the door body 6. When the door body 6 is forced to open the box body, it drives the second clamping portion 2 to exert a thrust away from the box body on the first clamping portion 11. Due to the interaction of forces, at this time, the first clamping portion 11 exerts a resistance of the same magnitude and towards the box body on the second clamping portion 2. When the external force applied is the same and both the first clamping portion 11 and the second clamping portion 2 extend along the width direction of the door body 6, at this time, the component force of the resistance of the first clamping portion 11 on the second clamping portion 2 in the width direction of the door body 6 is zero, and the component force of the resistance of the first clamping portion 11 on the second clamping portion 2 in the direction towards the box body is the largest. Therefore, at this time, the limiting effect of the first clamping portion 11 on the second clamping portion 2 is the best, and the effect of preventing the refrigerator door body 6 from accidentally opening is the best.

[0062] Optionally, please refer to Figure 6 , Figure 6The figure is a schematic structural diagram of the door locking assembly provided by the embodiment of the present application. The embodiment of the present application further includes a box body 4 and an elastic member 5. The box body 4 is snap-connected to the top of the door body 6 and is disposed opposite to the first snap-connection portion 11; one end of the elastic member 5 is connected to the box body 4, and the other end is connected to the second snap-connection portion 2. Here, the snap-connection manner between the box body 4 and the door body 6 is not further limited. For example, a snap can be provided on the box body 4, and a snap hole can be provided on the door body 6. The box body 4 is snap-connected into the snap hole through the snap, realizing the convenient disassembly and assembly of the box body 4.

[0063] That is, the second snap-connection portion 2 is elastically connected to the box body 4 through the elastic member 5. When the first snap-connection portion 11 and the second snap-connection portion 2 are in mutual abutment, the second snap-connection portion 2 is pressed by the first snap-connection portion 11 and moves toward the side close to the box body 4, and then is separated from the first snap-connection portion 11.

[0064] As an alternative embodiment, the first snap-connection portion 11 can be elastically connected to the hinge 1. For example, the first snap-connection portion 11 can be made of an elastic material, or the first snap-connection portion 11 is connected to the hinge 1 through the elastic member 5, so that when the first snap-connection portion 11 is pressed, it can move telescopically relative to the hinge 1 to realize separation from the second snap-connection portion 2, which will not be further described here.

[0065] Optionally, a receiving space 41 is provided inside the box body 4. A guide post 42 is provided in the receiving space 41 and extends in a direction close to or away from the first snap-connection portion 11. One end of the box body 4 facing the first snap-connection portion 11 is provided with a receiving hole 43, and the receiving hole 43 communicates with the receiving space 41; one end of the second snap-connection portion 2 slides along the guide post 42, and the other end movably passes through the receiving hole 43. Among them, the receiving hole 43 can be conformally matched with the second snap-connection portion 2, that is, the receiving hole 43 not only meets the extension requirement of the second snap-connection portion 2, but also can limit the second snap-connection portion 2 to prevent the second snap-connection portion 2 from shaking greatly.

[0066] That is, when the second snap-connection portion 2 slides relative to the box body 4 under force, it can slide under the guidance of the guide post 42, preventing the second snap-connection portion 2 from deforming under force and moving in a direction close to or away from the box body or other directions, restricting the movement path of the second snap-connection portion 2, ensuring the stability of the movement of the second snap-connection portion 2, and thus improving the service life of the second snap-connection portion 2.

[0067] Optionally, an installation rod 44 is further provided on one side of the receiving space 41 away from the receiving hole 43. The installation rod 44 extends along the sliding direction of the second snap-connection portion 2, and the elastic member 5 is sleeved on the installation rod 44.

[0068] The mounting rod 44 provides a mounting structure for the elastic member 5. One end of the elastic member 5 can be fixedly connected to the first side wall 45 of the housing 4 that encloses the accommodating space 41, and the other end is sleeved on the mounting rod 44 and fixedly connected to the second engaging portion 2. When the elastic member 5 moves with the second engaging portion 2, it can elastically deform along the extending direction of the mounting rod 44, preventing the elastic member 5 from bending and deforming towards the first side wall 45 of the mounting rod 44 and thus driving the second engaging portion 2 to move in the direction of approaching or departing from the box body.

[0069] No further limitation is imposed on the elastic member 5 here. In some examples, it can be a spring.

[0070] Furthermore, a receiving hole is recessed in the second engaging portion 2, and the receiving hole is conformally matched with the mounting rod 44. When the second engaging portion 2 is pressed and moves towards the inside of the housing 4, the second engaging portion 2 can be sleeved on the mounting rod 44 through the receiving hole. That is, the mounting rod 44 not only provides a mounting structure and a guiding structure for the elastic member 5, but also does not occupy the movement space of the second engaging portion 2, saving the volume of the housing 4, reducing costs and the installation space.

[0071] Optionally, a retaining block 22 protrudes from one side of the second engaging portion 2, and the retaining block 22 is located on the side of the second engaging portion 2 away from the first engaging portion 11; the housing 4 includes a first side wall 45 surrounding the periphery of the receiving hole 43. When the second engaging portion 2 slides out of the receiving hole 43 by a preset distance, the retaining block 22 is in limiting abutment with the first side wall 45. No further limitation is imposed on the preset distance here.

[0072] That is, by providing the retaining block 22, when the second engaging portion 2 is about to be pulled out of the housing 4, due to the abutment between the retaining block 22 and the first side wall 45 of the housing 4, the further detachment of the second engaging portion 2 from the housing 4 is restricted, ensuring that at least a part of the second engaging portion 2 is always located inside the housing 4. The second engaging portion 2 is limited by the receiving hole 43 and the guiding post 42 to ensure the stability of the movement of the second engaging portion 2.

[0073] Furthermore, a sliding groove can be provided through the retaining block 22, and the sliding groove is conformally matched with the guiding post 42. The second engaging portion 2 is slidably connected to the guiding post 42 through the sliding groove of the retaining block 22 and slides along the guiding post 42.

[0074] Optionally, there can be a pair of retaining blocks 22, which are respectively arranged on both sides of the second engaging portion 2. Correspondingly, there can also be a pair of corresponding guiding posts 42. Each retaining block 22 is slidably arranged on one guiding post 42, further improving the stability of the movement of the second engaging portion 2.

[0075] Optionally, a protective buckle 46 is further provided at one end of the box body 4 close to the first side wall 45. The protective buckle 46 extends into the accommodating space 41 and extends along the sliding direction of the second clamping portion 2. The protective buckle 46 and the box body 4 are clamped to form a deceleration groove, and the depth of the deceleration groove is less than or equal to the thickness of the second clamping portion 2. When the second clamping portion 2 slides close to the first side wall 45, it slides in line with the deceleration groove.

[0076] By providing a protective buckle 46 at one end of the first side wall 45 near the accommodating hole 43 on the box body 4, when the second clamping part 2 is about to be separated from the box body 4, the deceleration operation between the protective buckle 46 and the box body 4 is used to decelerate the second clamping part 2, thereby preventing the second clamping part 2 from being separated from the box body 4 and improving the stability of the movement of the second clamping part 2.

[0077] Furthermore, the protective buckle 46 cooperates with the anti-slip block 22 on the side of the second clamping part 2, that is, when the second clamping part 2 slides close to the first side wall 45, the anti-slip block 22 slides in line with the deceleration groove to reduce the sliding speed of the second clamping part 2, thereby reducing the force of the anti-slip block 22 hitting the first side wall 45 of the box body 4, thereby increasing the service life of each component.

[0078] Optionally, a flexible pad, such as rubber, is provided on the side of the protective buckle 46 facing the anti-slip block 22 , thereby reducing friction between the protective buckle 46 and the anti-slip block 22 .

[0079] Optionally, the protective buckle 46 can include a pair, and is separately arranged on the first side wall 45 of the box body 4 on both sides of the second clamping portion 2. The anti-slip block 22 also has a pair, and each protective buckle 46 cooperates with an anti-slip block 22 to further improve the deceleration effect of the protective buckle 46 on the anti-slip block 22.

[0080] Optionally, the end of the first clamping part 11 close to the second clamping part 2 may be provided with a first arc-shaped guide surface arched toward the second clamping part 2, and correspondingly, the end of the second clamping part 2 close to the first clamping part 11 is provided with a second arc-shaped guide surface arched toward the first clamping part 11. When the second clamping part 2 moves toward the box body from the end of the first clamping part 11 away from the box body and is clamped with the first clamping part 11, the first arc-shaped guide surface guides the second arc-shaped guide surface, so as to facilitate the clamping effect of the first clamping part 11 and the second clamping part 2, and prevent the occurrence of jamming during the clamping process. As an alternative embodiment, the second clamping part 2 is provided with a second arc-shaped guide surface at one end close to the first clamping part 11 and only toward one side of the box body, so that when the second clamping part 2 moves toward the box body from the end of the first clamping part 11 away from the box body and is clamped with the first clamping part 11, the first arc-shaped guide surface guides the second arc-shaped guide surface, thereby achieving the clamping effect of the first clamping part 11 and the second clamping part 2.
