Description

Slide assembly and refrigerator

Technical Field

The application relates to the technical field of electric appliances, in particular to a slide assembly and a refrigerator.

Background

Refrigerators are popular with users because they have both fresh-keeping and cold-storage functions. To facilitate storage and reduce cross-contamination, refrigerators often have compartment designs. Generally, the partition is composed of a partition plate and a slide rail, or a partition box and a slide rail assembly, and the slide rail can be used for providing a drawing channel for the partition plate or the partition box.

In the related art, a slide way is generally arranged between a front beam of a refrigerator and a front cover of an air duct of the refrigerator, and two ends of the slide way are fixed by supporting force provided by the front Liang Hefeng front covers respectively. However, since the refrigerator is easily deformed in the front beam or the front cover of the air duct due to deformation of the inner container of the refrigerator, the space for installing the slide rail in the refrigerator is contracted or enlarged.

Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Unless defined otherwise, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by one of ordinary skill in the art.

In order to make the technical scheme and advantages of the present application more apparent, embodiments of the present application will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present application provides a slide assembly including an elastic mechanism 100, a slide member 200, and a support member 300. The elastic mechanism 100 is connected between the chute member 200 and the support member 300. So that the distance between the chute member 200 and the support member 300 can be shortened or lengthened by the elastic mechanism 100.

The elastic mechanism 100 includes a cover 110 and an elastic piece 120, two sides of the elastic piece 120 respectively prop against the cover 110 and the slide member 200, and the elastic piece 120 has elasticity in the extending direction of the slide member 200. Wherein the cover 110 is movable relative to the chute member 200 in the extending direction of the chute member 200. Therefore, the cover 110 can be close to or far away from the slide member 200 under the elastic force of the elastic sheet 120, and the distance between the slide member 200 and the supporting member 300 is changed, so that the slide assembly has the capability of compensating for expansion and contraction, and the slide member 200 can be assembled in place in installation spaces with different sizes.

It will be appreciated that when the cover 110 moves in a direction approaching the slide member 200, the elastic sheet 120 is compressed by the cover 110 in the extending direction of the slide member 200, so that the cover 110 can approach the slide member 200, i.e. the length of the portion of the slide member 200 and the elastic mechanism 100 in the extending direction of the slide member 200 is reduced. Thus, even if the space for installing the chute member 200 is contracted in size, the chute member 200 can be assembled into the installation space of reduced size. In addition, under the elastic force of the elastic sheet 120, the cover 110 can be pushed to move away from the slide member 200, so that the length of the portion formed by the slide member 200 and the elastic mechanism 100 in the extending direction of the slide member 200 can be increased. Thus, even if the space for installing the chute member 200 becomes large in size, the chute member 200 can be assembled into the installation space of the large size.

It should be noted that, the support 300 provided in the embodiment of the present application may be a front beam in a refrigerator or an air duct front cover in a refrigerator. The slide member 200 may be used to provide support for a shelf or drawer for delamination within a refrigerator and may be provided with a slide rail 230 that mates with the shelf or drawer to allow the shelf or drawer to be pulled. The above-described space dimension of the installation chute member 200 may refer to the space dimension formed between the front beam and the duct front cover. Generally, the dimensional size of the installation chute member 200 may be due to deformation of the front beam, deformation of the front cover of the air duct caused by deformation of the refrigerator liner, foaming in the case, or deformation of other components.

Because the slideway component provided by the embodiment of the application has the capacity of compensating the expansion and contraction, the slideway component 200 can be assembled in place in installation spaces with different sizes, so that the slideway component is kept in a normal use state. That is, even if the support 300 is deformed to change the size of the installation space, for example, when the front beam is deformed or the front cover of the duct is deformed in the refrigerator to increase or decrease the size of the installation space, the chute member 200 can be assembled to a designated position or the installed chute member 200 is prevented from falling off, so that the chute member 200 is always assembled in place, that is, the connection state between the chute member 200 and the support 300 is always ensured.

Details and functions of the chute assembly according to the embodiments of the application are described in more detail below with reference to fig. 1 to 4.

As shown in fig. 2, in some embodiments, the cover 110 is provided with a first groove 111, and an opening of the first groove 111 faces the chute member 200. The walls of the first recess 111 are movably connected with the side walls of the chute member 200. The spring 120 is located inside the first recess 111. Thereby ensuring that the cover 110 can move relative to the chute member 200 and is not disengaged from the chute member 200. Meanwhile, since the elastic piece 120 is located in the first groove 111, the elastic piece 120 can be prevented from being separated from the cover 110 during the moving process.

As shown in connection with fig. 2 and 3, in some embodiments, the elastic sheet 120 includes a first support sheet 121, a first elastic portion 122, and a second elastic portion 123. The first supporting piece 121 abuts against the groove bottom 112 of the first groove 111. One end of the first elastic portion 122 is connected to the first surface 124 of the first supporting piece 121, and the other end of the first elastic portion 122 extends toward the slide member 200 and abuts against the end surface 210 of the slide member 200. One end of the second elastic portion 123 is connected to the first surface 124, and the other end of the second elastic portion 123 extends toward the chute member 200 and abuts against the end surface 210 of the chute member 200, where the first surface 124 is a surface of the first support piece 121 facing the chute member 200. It can be understood that when the size of the installation space is reduced, the cover 110 is pressed by the supporting member 300 and can move toward the slide member 200, so that the end of the first elastic portion 122 abutting against the end face 210 of the slide member 200 and the end of the second elastic portion 123 abutting against the end face 210 of the slide member 200 are elastically deformed and bent toward the direction approaching the first supporting piece 121, so that the length of the elastic sheet 120 in the direction perpendicular to the end face 210 of the slide member 200 is shortened, and the slide member 200 can be assembled into the installation space with reduced size. In addition, when the size of the installation space increases, the pressing force of the first elastic portion 122 and the second elastic portion 123 from the cover body 110 becomes smaller, and thus the lengths of the first elastic portion 122 and the second elastic portion 123 in the direction perpendicular to the end face 210 of the slide member 200 may increase, and further the elastic sheet 120 may push the cover body 110 to move in the direction away from the slide member 200, so that the slide member 200 may still be assembled into the installation space with increased size or the slide member 200 may be prevented from falling out from the installation space with increased size.

As shown in connection with fig. 2 and 3, in some embodiments, the cross-section of the first elastic portion 122 and the cross-section of the second elastic portion 123 are both arcuate. The concave surface of the first elastic portion 122 and the concave surface of the second elastic portion 123 face away from each other, at least a portion of the convex surface of the first elastic member abuts against the end surface 210 of the slide member 200, and at least a portion of the convex surface of the second elastic portion 123 abuts against the end surface 210 of the slide member 200. It should be noted that, the first elastic portion 122 and the second elastic portion 123 with arc-shaped cross sections are more easily kept in a state of being always abutted against the end surface 210 of the chute member 200.

As shown in fig. 2, in some embodiments, the first groove 111 includes oppositely disposed first and second groove walls 113, 114. The first elastic portion 122 is close to the first groove wall 113, and the concave surface of the first elastic portion 122 faces the first groove wall 113. The second elastic portion 123 is close to the second groove wall 114, and the concave surface of the second elastic portion 123 faces the second groove wall 114. When the first elastic portion 122 and the second elastic portion 123 are deformed, the end of the first elastic portion 122 abutting against the end face 210 of the slide member 200 and the end of the second elastic portion 123 abutting against the end face 210 of the slide member 200 are away from each other, so that the first elastic portion 122 and the second elastic portion 123 do not interfere with each other, and normal use of the slide assembly is ensured.

As shown in connection with fig. 2 and 3, in some embodiments, the first support sheet 121 has elasticity, and the first support sheet 121 has an arc-shaped cross section. The concave surface of the first support surface faces the groove bottom 112 of the first groove 111. Both the side of the first supporting piece 121 near the first groove wall 113 and the side of the first supporting piece 121 near the second groove wall 114 are propped against the groove bottom 112 of the first groove 111. It should be noted that, since the first supporting piece 121 also has elasticity, the bending degree of the first supporting piece 121 after being stressed can be increased or decreased, so that the cover body 110 is further away from or closer to the slide rail member 200, that is, the dimension variation range of the elastic piece 120 in the direction perpendicular to the end face 210 of the slide rail member 200 can be further increased, and further the dimension variation range of the portion formed by the elastic mechanism 100 and the slide rail member 200 can be increased, so that the slide rail member 200 can adapt to the installation space with a larger dimension variation range.

As shown in fig. 3, in some embodiments, the first support sheet 121 is provided with a first opening 125 and a second opening 126. The first opening 125 is opposite to the first elastic portion 122, and the second opening 126 is opposite to the second elastic portion 123. It can be understood that the first elastic portion 122 and the second elastic portion 123 are deformed when being stressed, and the first opening 125 and the second opening 126 can respectively provide accommodating spaces for the deformed first elastic portion 122 and second elastic portion 123, so as to ensure that the first elastic portion 122 and the second elastic portion 123 can be freely deformed.

As shown in fig. 2, in some embodiments, the end surface 210 of the chute member 200 is provided with an annular groove 220, with the opening of the annular groove 220 facing the cover 110. The groove wall of the first groove 111 is located in the annular groove 220, and the groove wall of the first groove 111 is movable in a direction perpendicular to the end face 210 of the slide member 200. With this arrangement, it is possible to ensure that the cover 110 can move smoothly in a direction perpendicular to the end face 210 of the chute member 200.

As shown in connection with fig. 2 and 4, in some embodiments, the outer sidewall of the first groove 111 is provided with at least one snap-fit element 115. The outer side wall of the annular groove 220 is provided with at least one clamping hole 221, the clamping piece 115 is positioned in the corresponding clamping hole 221, and the clamping piece 115 moves in the clamping hole 221 along the direction perpendicular to the end face 210 of the slideway piece 200. It can be understood that the movable distance of the clamping member 115 is limited by the clamping hole 221, so that the movable distance of the cover 110 in the direction perpendicular to the end surface 210 of the slide member 200 can be limited, the phenomenon that the cover 110 excessively moves to squeeze or separate from the slide member 200 is avoided, the cover 110 and the slide member 200 are always connected, and the cover 110 and the slide member 200 are prevented from being damaged. It should be noted that the number of the clamping members 115 may be one, two or more, and the clamping members 115 may be disposed on any outer sidewall of the annular groove 220.

As shown in fig. 2, in some embodiments, a baffle member 116 is attached to an outer sidewall of the first recess 111, the baffle member 116 extending in a direction away from the first recess 111. When the clamping piece 115 abuts against one side of the clamping hole 221 away from the cover body 110, the baffle piece 116 abuts against the groove top of the annular groove 220. It should be noted that, by providing the baffle member 116, the moving position of the cover 110 can be further limited, so that the phenomenon that the cover 110 or the slide member 200 is damaged due to excessive extrusion caused by excessive movement of the cover 110 toward the slide member 200 is avoided, and the service life of the slide assembly is prolonged.

As shown in fig. 1, in some embodiments, the ramp assembly includes two spring mechanisms 100 and two supports 300, with the spring mechanisms 100 and supports 300 being in one-to-one correspondence. One of the two elastic mechanisms 100 is located between one end of the chute member 200 and the corresponding support member 300, and the other is located between the other end of the chute member 200 and the corresponding support member 300. It should be noted that, the two supporting members 300 may be a front beam and a front cover of the air duct in the refrigerator, where one elastic mechanism 100 is located between the front beam and one end of the slide member 200, and the other elastic mechanism is located between the front cover of the air duct and the other end of the slide member 200. By arranging the two elastic mechanisms 100, the moving range of the cover body 110 relative to the slideway component 200 can be increased, so that the compensation expansion capacity of the slideway component is improved, and the compensation range of the two sides of the slideway component 200 is larger, namely the compensation compatibility is stronger. Therefore, even if the size change range of the installation space is large, the slideway member 200 can be normally installed and the slideway member 200 can be assembled in place, and the phenomenon that the slideway member 200 falls off due to the change of the size of the installation space can be avoided, so that the normal use of the slideway member 200 is ensured.

In some embodiments, the cover 110 is connected to the corresponding support 300 by a locking mechanism, and/or one end of the chute member 200 is connected to the support 300 by a locking mechanism. Thereby being more convenient for assembling or disassembling the slideway component, namely improving the assembling efficiency and the disassembling efficiency. Meanwhile, after the slideway assembly is detached more conveniently, the slideway assembly and parts around the slideway assembly are cleaned, so that the experience of the user is improved.

On the other hand, the embodiment of the application also provides a refrigerator, which comprises the slide rail assembly according to any one of the embodiment of the application. It should be noted that, the slide assembly in the refrigerator provided by the embodiment of the present application has the same composition and function as the slide assembly provided in the above embodiment of the present application, and the embodiments of the present application are not described herein again. Because the slideway component has the capacity of compensating and telescoping, the slideway component 200 can be assembled in place in installation spaces with different sizes, so that the slideway component is kept in a normal use state, the refrigerator is further ensured to be in the normal use state, and the maintenance cost and the manufacturing cost of the refrigerator are reduced.

As shown in fig. 1, in some embodiments, the refrigerator includes two supports 300, one of which 300 is a front beam and the other 300 is a duct front cover. It will be appreciated that a mounting space may be formed between the front beam and the air duct front cover in the refrigerator to mount the chute member 200.

As shown in fig. 1, in some embodiments, the refrigerator includes at least one drawer and/or at least one partition. The outer wall of the slideway element 200 is provided with a slideway 230, and the drawer is matched with the corresponding slideway 230 to realize drawing. And/or the spacer cooperates with a corresponding slide rail 230 to effect the drawing. So that the partition and/or the drawer can be movably installed inside the refrigerator to achieve a separate storage effect. It should be noted that the number of the sliding rails 230 may be set according to the requirement. Since the elastic mechanism 100 can be extended or shortened between the chute member 200 and the front beam, and/or between the chute member 200 and the duct front cover, the varying sizes of both ends of the support 300 can be well compensated. That is, even if the front beam or the duct front cover is deformed, resulting in a smaller or larger size of the installation space formed between the front beam and the duct front cover, it is ensured that the slide member 200 can be assembled in place, thereby ensuring normal use of the refrigerator.

Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the application following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the application pertains.
