Description

Technical Field

[0001] The present invention relates to the technical field of refrigerator structure design, and more particularly, to a door locking structure and a refrigerator. Background Art

[0002] In the related art, the refrigerator drawer door is mainly locked in the following two ways.

[0003] In some solutions, a sloping sinking structure is usually designed at one end of the guide rail of the refrigerator drawer door. By using the slope of the guide rail, the drawer door can be locked and sealed by its own weight when it is closed. However, due to the slope of the guide rail, the drawer door will be tilted as a whole after being locked, resulting in inconsistent upper and lower heights after the door seal is attracted, which affects the sealing consistency of the refrigerator door seal. This may not only cause cold air leakage, but also require readjusting the assembly slope of the guide rail due to the large difference in upper and lower heights, increasing the complexity of design and assembly.

[0004] In other solutions, metal slide rails with locking springs may be provided on the left and right sides of the drawer box body of the externally pulled refrigerator drawer door, and the locking and sealing functions are realized through the locking springs in the slide rails. This solution has certain advantages in terms of technology and locking and sealing, but its implementation cost is relatively high and it is mainly applied to high-end products. Summary of the Invention

[0005] In order to at least overcome the above deficiencies in the prior art, the purpose of the present invention is to provide a door locking structure and a refrigerator.

[0006] In a first aspect, an embodiment of the present invention provides a door locking structure, which is applied to a refrigerator. The refrigerator includes a box body and a door, and the box body includes a first side wall adjacent to the door;

[0007] The door locking structure includes a first locking structure and a second locking structure. The first locking structure is located on the first side wall and is close to the door, and the second locking structure is located on the door and is close to the first side wall;

[0008] The first locking structure includes a box body fixed support seat and a locking assembly. The box body fixed support seat is fixedly connected to the first side wall, and the locking assembly is arranged on the box body fixed support seat;

[0009] The box body fixed support seat includes a first slide rail, and the extending direction of the first slide rail is the same as the extending direction of the box body fixed support seat;

[0010] The second locking structure includes a door fixed support seat and a dial arranged on the door fixed support seat;

[0011] One end of the box door fixed support is fixedly connected to the box door, and the box door fixed support includes a first slider, and the first slider is connected to the box body fixed support and the box door fixed support by cooperating with the first slide rail;

[0012] When the box door is opened, the first slider moves on the first slide rail in a direction close to the box door, and the paddle is separated from the locking assembly;

[0013] When the box door is closed, the first sliding block moves on the first sliding rail in a direction away from the box door, and the paddle is engaged with the locking assembly.

[0014] In this embodiment, the tension of the elastic member provides the locking assembly with a reset force, so that the door can be automatically locked, ensuring the sealing between the door and the box body to prevent cold air leakage. In addition, the automatic locking of the door can be achieved through the coordinated cooperation of the paddle, the second slider and the elastic member, which can also reduce the structural complexity and cost of the locking assembly and save the installation space required for the door locking structure.

[0015] In a possible implementation, the locking assembly includes a second slide rail, a second slider, and an elastic member, wherein an extension direction of the second slide rail is parallel to an extension direction of the first slide rail;

[0016] The second slider cooperates with the second slide rail, the elastic member is connected to the second slider, and a switch limit portion is provided at one end of the second slider close to the first slide rail;

[0017] When the box door is opened, the paddle drives the second slider to move on the second slide rail in a direction close to the box door through the switch limiting portion, the paddle is separated from the switch limiting portion, and the elastic member has a first deformation length;

[0018] When the box door is closed, the paddle drives the second slider to move on the second slide rail in a direction away from the box door through the switch limit portion, and the paddle cooperates with the switch limit portion, and the box door is locked under the elastic force of the elastic member, wherein the elastic member has a second deformation length, and the second deformation length is smaller than the first deformation length.

[0019] In this embodiment, the stretching force of the elastic member provides the reset power for the locking assembly, enabling automatic locking of the box door, ensuring the sealing between the box door and the box body, and preventing cold air leakage. In addition, through the collaborative cooperation of the dial, the second slider, and the elastic member to achieve automatic locking of the box door, the structural complexity and cost of the locking assembly can be reduced, and the installation space required for the box door locking structure can be saved.

[0020] In a possible implementation, the elastic member includes a spring.

[0021] In a possible implementation, the locking assembly further includes a damping member connected to the second slider;

[0022] The elastic member and the damping member are arranged in parallel, and the extending direction of the elastic member and / or the extending direction of the damping member is the same as the extending direction of the second slide rail.

[0023] In the above structure, the damping member can not only buffer the impact force generated during the closing or opening process of the box door, reduce the vibration of the box body, protect the locking structure and the box body from damage, but also absorb the energy generated during the movement process, reduce noise, and improve the user experience.

[0024] In a possible implementation, the box body fixed support seat includes a fixed card slot provided at the bottom;

[0025] The locking assembly further includes a fixed buckle, and the box body fixed support seat and the locking assembly are fixed through the cooperation of the fixed buckle and the fixed card slot.

[0026] By fixing and installing the box body fixed support seat and the locking assembly through the cooperation of the fixed buckle and the fixed card slot, the disassembly and assembly process of the locking assembly can be effectively simplified, and the maintenance cost can be reduced. At the same time, different specifications of locking assemblies can be replaced according to different specifications of the box body, improving the universality and flexibility of the box door locking structure.

[0027] In a possible implementation, the locking assembly further includes a first claw, and the first claw is fixedly connected to the box body fixed support seat.

[0028] In this way, the connection stability and reliability between the locking assembly and the box body fixed support seat can be effectively improved, ensuring that the locking assembly does not undergo displacement or deformation during the frequent opening and closing of the box door.

[0029] In a possible implementation, the box body fixed support seat further includes a fixed through hole, and the fixed through hole is located on the periphery of the first slide rail and the locking assembly;

[0030] The door locking structure of the box further includes a fixing member, and the fixing member passes through the fixing through hole to fixedly connect the box fixing support seat and the first side wall.

[0031] In this way, while ensuring the installation stability of the box fixing support seat, the door locking structure of the box can also be applied to refrigerators of different specifications, improving the applicability of the door locking structure of the box.

[0032] In a possible implementation manner, the box fixing support seat further includes at least one second claw;

[0033] The box fixing support seat includes an opposite first surface and a second surface. The first slide rail and the locking assembly are located on the first surface, and the second claw is located on the second surface. The second claw is fixedly connected to the first side wall.

[0034] In the above structure, the second claw can ensure that the box fixing support seat will not be displaced or loosened during long-term use, further improving the installation stability and reliability of the box fixing support seat.

[0035] In a possible implementation manner, the box fixing support seat further includes a rib structure, and the rib structure is located on the second surface.

[0036] In the above structure, the rib structure can effectively and significantly improve the structural strength of the box fixing support seat, prevent structural damage caused by local stress concentration, and extend the service life.

[0037] In a second aspect, an embodiment of the present invention further provides a refrigerator, which includes a box body, a box door, and the door locking structure according to any one of the first aspects. The door locking structure is used to connect the box body and the box door.

[0038] Based on any one of the above aspects, the door locking structure and the refrigerator provided by the embodiments of the present invention include a first locking structure and a second locking structure.

When the box door is closed, the first slider moves along the direction away from the box door on the first slide rail, and the paddle is engaged with the locking assembly. In this way, without modifying the door structure, the box door can be automatically locked through the cooperation of the first locking structure and the second locking structure, reducing the manufacturing cost while improving the reliability and stability of locking, and ensuring the sealing performance and refrigeration effect of the refrigerator.

[0051] To solve the problems in the background art, the inventor innovatively designs the following technical solutions. The specific implementation solutions of the present invention will be described in detail below with reference to the drawings. It should be noted that the defects existing in the above prior art solutions are all the results obtained by the inventor through practice and careful research. Therefore, the discovery process of the above technical problems and the solutions proposed by the following embodiments of the present invention for the above problems should all be the contributions made by the inventor to the present invention during the invention creation process, and should not be construed as the technical content known to those skilled in the art.

[0052] To solve the problems in the prior art, please refer to Figure 1 , an embodiment of the present invention provides a door locking structure 10, which can be applied to a refrigerator. The refrigerator includes a box body 210 and a door 220. The box body 210 includes a first side wall adjacent to the door 220.

[0053] Please refer to Figure 2 , the door locking structure 10 includes a first locking structure 11 and a second locking structure 12. The first locking structure 11 is located on the first side wall and is disposed close to the door 220. The second locking structure 12 is located on the door 220 and is disposed close to the first side wall. Specifically, the first locking structure 11 and the second locking structure 12 are disposed on the same side and are in position correspondence, and the door 220 is locked through the cooperation of the first locking structure 11 and the second locking structure 12.

[0054] The first locking structure 11 may include a box body fixed support base 111 and a locking component 112. The box body fixed support base 111 is fixedly connected to the first side wall, and the locking component 112 is arranged on the box body fixed support base 111. The box body fixed support base 111 includes a first slide rail. The extending direction of the first slide rail is the same as the extending direction of the box body fixed support base 111, and the extending direction of the first slide rail and / or the extending direction of the box body fixed support base 111 is perpendicular to the plane where the box door 220 is located. The second locking structure 12 includes a box door fixed support base 121 and a flap 122 arranged on the box door fixed support base 121. The extending direction of the flap 122 is perpendicular to the extending direction of the box door fixed support base 121. One end of the box door fixed support base 121 is fixedly connected to the box door 220. The box door fixed support base 121 includes a first slider, and the first slider connects the box body fixed support base 111 and the box door fixed support base 121 by cooperating with the first slide rail.

[0055] In the above structure, when the box door 220 is opened, the first slider moves along the first slide rail in the direction close to the box door 220, and the flap 122 is separated from the locking component 112. When the box door 220 is closed, the first slider moves along the first slide rail in the direction away from the box door 220, and the flap 122 is engaged with the locking component 112. In this way, without modifying the structure of the box door 220, the automatic locking of the box door 220 can be realized through the cooperation of the first locking structure 11 and the second locking structure 12, improving the reliability and stability of locking, and ensuring the sealing performance and refrigeration effect of the refrigerator. In addition, compared with the scheme of using a metal slide rail, the manufacturing cost of the box door locking structure 10 provided by the present invention is lower.

[0056] In some possible embodiments, please refer to Figure 3 , the locking component 112 includes a second slide rail 1121, a second slider 1122 and an elastic member 1123. The extending direction of the second slide rail 1121 is parallel to the extending direction of the first slide rail. The second slider 1122 cooperates with the second slide rail 1121. The elastic member 1123 is connected to the second slider 1122. A switch limiting portion is arranged at one end of the second slider 1122 close to the first slide rail. The switch limiting portion can limit the movement of the flap 122 during the locking and unlocking processes, preventing the second slider 1122 from sliding excessively and causing structural failure. Among them, due to the small size deviation of the second slide rail 1121, the second slider 1122 can run smoothly along the second slide rail 1121, avoiding local stress concentration or wear caused by size deviation, and prolonging the service life of the second slide rail 1121 and the second slider 1122.

[0057] In the above structure, please refer to Figure 4 , when the cabinet door 220 is opened, the paddle 122 drives the second slider 1122 to move along the second slide rail 1121 in a direction close to the cabinet door 220 through the switch limiting part until the paddle 122 is separated from the switch limiting part, and the elastic member 1123 has a first deformation length. Specifically, at this time, the elastic member 1123 may be in a stretched state, and the acting force generated by it is in the direction opposite to the moving direction of the second slider 1122. When the cabinet door 220 is closed, the paddle 122 can drive the second slider 1122 to move along the second slide rail 1121 in a direction away from the cabinet door 220 through the switch limiting part. The paddle 122 cooperates with the switch limiting part, and the cabinet door 220 is locked under the elastic acting force of the elastic member 1123. Among them, the elastic member 1123 has a second deformation length, and the second deformation length is less than the first deformation length. Specifically, the elastic member 1123 may be in a reset state. Exemplarily, the elastic member 1123 includes a spring.

[0058] In this embodiment, the tensile force of the elastic member 1123 provides a reset power for the locking assembly 112, so that the automatic locking of the cabinet door 220 can be realized, the sealing performance between the cabinet door 220 and the cabinet body 210 can be ensured, and cold air leakage can be prevented. In addition, the automatic locking of the cabinet door 220 is realized through the coordinated cooperation of the paddle 122, the second slider 1122 and the elastic member 1123, which can also reduce the structural complexity and cost of the locking assembly 112 and save the installation space required for the cabinet door locking structure 10.

[0059] Furthermore, please refer to again Figure 3, the locking assembly 112 further includes a damping member 1124 connected to the second slider 1122. The elastic member 1123 can be arranged in parallel with the damping member 1124, and the extending direction of the elastic member 1123 and / or the extending direction of the damping member 1124 is the same as the extending direction of the second slide rail 1121. Specifically, when the cabinet door 220 is opened, the damping member 1124 can control the stretching process of the elastic member 1123, making the separation of the dial 122 from the switch limit part smoother. When the cabinet door 220 is closed, the damping member 1124 can provide a stable damping force, making the dial 122 and the second slider 1122 move more smoothly during the movement, avoiding excessive movement or shaking caused by inertia, and improving the locking accuracy and reliability. At the same time, the damping member 1124 can also buffer the impact force generated during the closing or opening process of the cabinet door 220, so that the cabinet door 220 can be locked smoothly without generating a large impact force due to the sudden reset of the elastic member 1123, protecting the locking structure and the cabinet body 210 from damage.

[0060] In the above structure, the damping member 1124 can not only buffer the impact force generated during the closing or opening process of the cabinet door 220, reduce the vibration of the cabinet body 210, protect the locking structure and the cabinet body 210 from damage, but also absorb the energy generated during the movement process, reduce noise, and improve the user experience.

[0061] In some other possible embodiments, please refer to Figure 5 , the cabinet body fixed support base 111 includes a fixed card slot 1111 arranged at the bottom. The locking assembly 112 further includes a fixed buckle 1125. The cabinet body fixed support base 111 and the locking assembly 112 are fixed by the cooperation of the fixed buckle 1125 and the fixed card slot 1111. By fixing and installing the cabinet body fixed support base 111 and the locking assembly 112 through the cooperation of the fixed buckle 1125 and the fixed card slot 1111, the disassembly and assembly process of the locking assembly 112 can be effectively simplified, and the maintenance cost can be reduced. At the same time, the locking assembly 112 of different specifications can also be replaced according to different specifications of the cabinet body 210, improving the universality and flexibility of the cabinet door locking structure 10.

[0062] Optionally, please refer to again Figure 5 , the locking assembly 112 may further include a first claw 1126, and the first claw 1126 is fixedly connected to the cabinet body fixed support base 111. In this way, the connection stability and reliability between the locking assembly 112 and the cabinet body fixed support base 111 can be effectively improved, ensuring that the locking assembly 112 will not be displaced or deformed during the frequent opening and closing process of the cabinet door 220.

[0063] Further, please refer to Figure 5 again. The box body fixing support seat 111 may further include a fixing through hole 1112, and the fixing through hole 1112 is located on the periphery of the first slide rail and the locking assembly 112. The box door locking structure 10 further includes a fixing member, and the fixing member passes through the fixing through hole 1112 to fixedly connect the box body fixing support seat 111 with the first side wall. Exemplarily, the fixing member may be a screw, and the first side wall may be provided with a corresponding threaded hole, and the box body fixing support seat 111 is installed on the first side wall by the cooperation of the screw and the threaded hole. In this way, while ensuring the installation stability of the box body fixing support seat 111, the box door locking structure 10 can also be applied to refrigerators of different specifications, improving the applicability of the box door locking structure 10.

[0064] Optionally, please refer to Figure 5 again. The box body fixing support seat 111 may further include at least one second claw 1113. The box body fixing support seat 111 includes opposite first and second surfaces. The first slide rail and the locking assembly 112 are located on the first surface, and the second claw 1113 is located on the second surface. The second claw 1113 is fixedly connected to the first side wall. The second claw 1113 can ensure that the box body fixing support seat 111 will not be displaced or loosened during long-term use, further improving the installation stability and reliability of the box body fixing support seat 111.

[0065] Optionally, please refer to Figure 5 again. The box body fixing support seat 111 may further include a rib structure, and the rib structure is located on the second surface. The rib structure can effectively and significantly improve the structural strength of the box body fixing support seat 111, prevent structural damage caused by local stress concentration, and extend the service life.

[0066] Based on the same inventive concept, the present invention also provides a refrigerator, which includes a box body 210, a box door 220, and a box door locking structure 10 for connecting the box body 210 and the box door 220.

[0067] Please refer to Figure 1 and Figure 2 again. The box door locking structure 10 includes a first locking structure 11 and a second locking structure 12. The first locking structure 11 is located on the first side wall and is disposed close to the box door 220, and the second locking structure 12 is located on the box door 220 and is disposed close to the first side wall. Specifically, the first locking structure 11 and the second locking structure 12 are disposed on the same side and in corresponding positions, and the box door 220 is locked by the cooperation of the first locking structure 11 and the second locking structure 12.

[0068] The first locking structure 11 may include a box body fixed support seat 111 and a locking assembly 112. The box body fixed support seat 111 is fixedly connected to the first side wall, and the locking assembly 112 is arranged on the box body fixed support seat 111. The box body fixed support seat 111 includes a first slide rail. The extending direction of the first slide rail is consistent with the extending direction of the box body fixed support seat 111, and the extending direction of the first slide rail and / or the extending direction of the box body fixed support seat 111 is perpendicular to the plane where the box door 220 is located. The second locking structure 12 includes a box door fixed support seat 121 and a dial 122 arranged on the box door fixed support seat 121. The extending direction of the dial 122 is perpendicular to the extending direction of the box door fixed support seat 121. One end of the box door fixed support seat 121 is fixedly connected to the box door 220. The box door fixed support seat 121 includes a first slider, and the first slider connects the box body fixed support seat 111 and the box door fixed support seat 121 by cooperating with the first slide rail.

[0069] In the above structure, when the box door 220 is opened, the first slider moves along the direction close to the box door 220 on the first slide rail, and the dial 122 is separated from the locking assembly 112. When the box door 220 is closed, the first slider moves along the direction away from the box door 220 on the first slide rail, and the dial 122 is engaged with the locking assembly 112.

[0070] In this embodiment, the tensile force of the elastic member 1123 provides a reset power for the locking assembly 112, so that the automatic locking of the box door 220 can be realized, the sealing performance between the box door 220 and the box body 210 can be ensured, and the leakage of cold air can be prevented. In addition, the automatic locking of the box door 220 is realized through the coordinated cooperation of the dial 122, the second slider 1122 and the elastic member 1123, which can also reduce the structural complexity and cost of the locking assembly 112 and save the installation space required by the box door locking structure 10.

[0071] Further, please refer to again Figure 3, the locking assembly 112 also includes a damping member 1124 connected to the second slider 1122, the elastic member 1123 can be arranged in parallel with the damping member 1124, and the extension direction of the elastic member 1123 and / or the extension direction of the damping member 1124 is the same as the extension direction of the second slide rail 1121. Specifically, when the door 220 is opened, the damping member 1124 can control the stretching process of the elastic member 1123, so that the paddle 122 and the switch limiter are separated more smoothly. When the door 220 is closed, the damping member 1124 can provide a stable damping force, so that the paddle 122 and the second slider 1122 are more stable during the movement process, avoiding excessive movement or shaking caused by inertia, and improving the accuracy and reliability of locking. At the same time, the damping member 1124 can also buffer the impact force generated by the box door 220 during the closing or opening process, so that the box door 220 can be locked smoothly without generating a large impact force due to the sudden resetting of the elastic member 1123, thereby protecting the locking structure and the box body 210 from damage.

[0072] Further, please refer again to Figure 3 , the locking assembly 112 also includes a damping member 1124 connected to the second slider 1122, the elastic member 1123 can be arranged in parallel with the damping member 1124, and the extension direction of the elastic member 1123 and / or the extension direction of the damping member 1124 is the same as the extension direction of the second slide rail 1121.

When the door 220 is closed, the damping member 1124 can provide a stable damping force, so that the paddle 122 and the second slider 1122 are more stable during the movement process, avoiding excessive movement or shaking caused by inertia, and improving the accuracy and reliability of locking. At the same time, the damping member 1124 can also buffer the impact force generated by the box door 220 during the closing or opening process, so that the box door 220 can be locked smoothly without generating a large impact force due to the sudden resetting of the elastic member 1123, thereby protecting the locking structure and the box body 210 from damage.

[0073] In summary, the present invention provides a door locking structure and a refrigerator. The above-mentioned door locking structure includes a first locking structure and a second locking structure. The first locking structure may include a box body fixed support seat and a locking assembly. The box body fixed support seat is fixedly connected to the first side wall, and the locking assembly is arranged on the box body fixed support seat. The second locking structure includes a door fixed support seat and a dial arranged on the door fixed support seat. When the door is opened, the first slider moves along the direction close to the door on the first slide rail, and the dial is separated from the locking assembly. When the door is closed, the first slider moves along the direction away from the door on the first slide rail, and the dial is engaged with the locking assembly. In this way, without modifying the door structure, the automatic locking of the door can be achieved through the cooperation of the first locking structure and the second locking structure, reducing the manufacturing cost while improving the reliability and stability of locking, and ensuring the sealing performance and refrigeration effect of the refrigerator.
