Description

Guide rail mechanism, storage drawers and refrigerator Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a guide rail mechanism, a storage drawer, and a refrigerator. Background Technology

[0002] Currently, to facilitate storage and prevent food odors from mixing, refrigerators typically have multiple storage drawers to separate different types of food. Each drawer is equipped with casters and rails at the bottom for easy pulling out.

[0003] However, if too much force is used when pulling out a storage drawer, the drawer may move too quickly. Especially when opening a drawer, a sudden increase in speed can easily cause a collision, posing a safety hazard. Summary of the Invention

[0004] Therefore, it is necessary to provide a guide rail mechanism that can reduce the space for the moving rollers to move within the roller grooves, thereby increasing the friction of the moving rollers, achieving the purpose of deceleration, and thus limiting the moving speed of the drawer body and reducing the risk of collision.

[0005] A guide rail mechanism is provided for installation between a drawer body and a cavity. The guide rail mechanism includes a movable roller, a movable guide rail, and a deceleration assembly. The movable roller is used to connect to the drawer body. The movable guide rail includes an upper guide rail and a lower guide rail, which are arranged at intervals along a first direction and together form a roller groove. The upper guide rail and / or the lower guide rail has an installation notch that extends through the first direction. The first direction is angled to the length direction of the roller groove. The deceleration assembly includes an adjusting seat and an elastic element. The adjusting seat is movably disposed on the movable guide rail and located at the installation notch. The elastic element is connected to the movable guide rail and presses against the adjusting seat, for driving the adjusting seat to extend into the roller groove along the first direction.

[0006] Understandably, the use of the rolling motion of the movable rollers within their grooves allows the drawer to be pulled out from behind the interior, facilitating the loading and unloading of food. The notch in the mounting bracket allows the movable rollers to engage with the adjusting seat when they reach it. Furthermore, because the adjusting seat, under the action of the elastic element, tends to extend into the roller groove, the space available for the movable rollers to pass through at the mounting bracket is reduced, increasing the friction between the movable rollers and the adjusting seat, thus increasing the rolling resistance and achieving deceleration. In this way, the movement speed of the drawer is limited, ensuring that the drawer slides in and out as smoothly as possible, reducing the risk of collision.

[0007] In some embodiments, the movable guide rail has a free side and a positioning side that are arranged opposite to each other and spaced apart along the length direction of the roller groove, and the mounting notch is provided at one end of the roller groove near the free side; and / or, along the length direction of the roller groove, both sides of the adjusting seat are provided with transition surfaces.

[0008] In some embodiments, the deceleration assembly further includes a fixed seat disposed on the moving guide rail, an adjusting seat slidably connected to the fixed seat, and an elastic element pressing against the adjusting seat and the fixed seat.

[0009] In some embodiments, the deceleration assembly further includes an adjusting member movably connected to the fixed base and to the elastic member, the adjusting member being used to tighten or loosen the elastic member.

[0010] In some embodiments, the elastic element is a wave-shaped spring sheet having a crest section and a trough section. The crest section abuts against the adjusting seat, and the trough section is connected to the adjusting member, which is used to adjust the distance between the trough section and the adjusting seat.

[0011] In some embodiments, the upper guide rail and / or the lower guide rail are provided with a limiting portion on the side facing the roller groove, the limiting portion being able to abut against the movable roller to limit displacement.

[0012] In some embodiments, the guide rail mechanism further includes a slide roller rotatably connected to the movable guide rail, the slide roller partially protruding from the roller groove.

[0013] In some embodiments, the movable guide rail has a free side and a positioning side, which are arranged opposite to each other and spaced apart along the length of the roller groove; the movable guide rail is provided with a limiting baffle on the positioning side, and the lower guide rail is provided with a groove communicating with the roller groove near the positioning side.

[0014] This application also provides a storage drawer, including a drawer body, a tray and the aforementioned guide rail mechanism, wherein the movable rollers in the guide rail mechanism are rotatably connected to the tray, and the drawer body is supported on the tray.

[0015] This application also provides a refrigerator, including a cabinet, a refrigeration circuit and the above-mentioned storage drawers; the cabinet is provided with a first chamber, a second chamber and a third chamber, and the storage drawers are provided in a plurality of them and arranged at intervals along the vertical direction in the third chamber; the first chamber, the second chamber and the third chamber are each provided with an evaporator, and each of the evaporators is connected to the refrigeration circuit.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0035] Please refer to Figures 1 and 2. This application provides a storage drawer 100, including a drawer body 120 and a guide rail mechanism 110. The drawer body 120 is installed in the cavity where the storage drawer 100 needs to be installed through the guide rail mechanism 110, which is convenient for the refrigerator cavity. The drawer body 120 can slide and pull out under the action of the guide rail mechanism 110, which is convenient for users to take out and put in items (or food).

[0036] Please refer to Figures 1 to 6. The guide rail mechanism 110 includes a movable roller 111, a movable guide rail 112, and a reduction gear assembly 113. The movable roller 111 is used to connect to the drawer body 120. The movable guide rail 112 includes an upper guide rail 1121 and a lower guide rail 1122, which are spaced apart along a first direction and together form a roller groove 1126. The upper guide rail 1121 and / or the lower guide rail 1122 are provided with a mounting notch 1123 extending along the first direction, which is angled to the length direction of the roller groove 1126. The reduction gear assembly 113 includes an adjusting seat 1131 and an elastic element 1132. The adjusting seat 1131 is movably disposed on the movable guide rail 112 and located at the mounting notch 1123. The elastic element 1132 is connected to the movable guide rail 112 and presses against the adjusting seat 1131, driving the adjusting seat 1131 to extend into the roller groove 1126 along the first direction.

[0037] Taking the vertically spaced guide rails 1121 and 1122 as an example, the first direction is the Z-axis direction, the length direction of the roller groove 1126 is the Y-axis direction, and the width direction of the roller groove 1126 is the X-axis direction, which is the axial direction of the movable roller 111. The movable roller 111 is connected to the drawer body 120 through a pivot, and the movable roller 111 can rotate around the axis of the pivot. Taking the mounting notch 1123 located on the lower guide rail 1122 as an example, the adjusting seat 1131, under the action of the elastic element 1132, has a tendency to move towards the upper guide rail 1121 along the Z-axis direction.

[0038] In actual use, as the user pulls out the drawer body 120, the movable roller 111 rolls within the roller groove 1126. The movable roller 111 experiences rolling friction with the side walls of the upper guide rail 1121 and lower guide rail 1122 facing the roller groove 1126. When the movable roller 111 rolls to the mounting notch 1123, it can be supported on the adjusting seat 1131. At this time, due to the action of the elastic element 1132, the adjusting seat 1131 moves closer to the upper guide rail 1121 along the Z-axis, causing the dimension between the adjusting seat 1131 and the upper guide rail 1121 along the Z-axis to decrease. Furthermore, it is precisely because of the setting of the elastic element 1132 that the adjusting seat 1131 has a floating property along the Z-axis, which makes it easier for the movable roller 111 to move to the adjusting seat 1131. Therefore, when the moving roller 111 moves to the adjusting seat 1131, the distance through which the moving roller 111 passes is reduced, and sliding friction is formed between the moving roller 111 and the adjusting seat 1131 and the upper guide rail 1121. That is, the frictional force between the moving roller 111 and the adjusting seat 1131 and the upper guide rail 1121 is increased, thereby achieving the purpose of deceleration. Therefore, when the guide rail mechanism 110 is used for the drawer body 120 to be pulled out, it can better limit the moving speed of the drawer body 120, ensuring that the drawer body 120 can move as smoothly as possible and reducing the risk of collision.

[0039] The upper guide rail 1121 and the lower guide rail 1122 each have protruding strips on opposite sides to limit the axial (X-axis) displacement of the moving roller 111. The cross-sections of both the upper and lower guide rails 1121 and 1122 can be U-shaped, with the opening of the U facing away from the moving roller 111 along the X-axis. In this case, the lower guide rail 1122 may have a through mounting notch 1123 on one side wall of the roller groove 1126. In practical use, the moving guide rail 112 also includes an integrated substrate 1125, on which both the upper and lower guide rails 1121 and 1122 are fixed. The integrated substrate 1125 can be connected to the target location where the moving guide rail 112 needs to be installed. The integrated substrate 1125, the upper guide rail 1121, and the lower guide rail 1122 can all be integrally formed.

[0040] Alternatively, the upper guide rail 1121 may have a mounting notch 1123, and the adjusting seat 1131 may protrude downward along the Z-axis direction from the lower guide rail 1122 under the action of the elastic element 1132, i.e., close to the lower guide rail 1122, to reduce the size of the moving roller 111 along the Z-axis direction when it passes through, thus achieving the purpose of deceleration. Alternatively, both the upper guide rail 1121 and the lower guide rail 1122 may have mounting notches 1123. The two mounting notches 1123 may be arranged opposite each other along the Z-axis direction or staggered along the Y-axis direction. Each mounting notch 1123 may correspond to a set of deceleration components 113, as long as they can meet the movement deceleration requirements of the moving roller 111.

[0041] As shown in Figures 1 and 2, in some embodiments, the movable guide rail 112 has a free side 112b and a stationary side 112a arranged opposite to each other and spaced apart along the length direction (i.e., the Y-axis direction) of the roller groove 1126. A mounting notch 1123 is provided at one end of the roller groove 1126 near the free side 112b. It can be understood that the free side 112b is the side where the drawer body 120 slides in and out, and the stationary side 112a is the side where the drawer body 120 slides into place. Therefore, by utilizing the mounting notch 1123 located near the free side 112b, i.e., by placing the deceleration assembly 113 near the free side 112b, it is beneficial to decelerate the drawer body 120 when it slides out, thereby reducing the risk of collision. In addition, if the gap between the adjusting seat 1131 and the upper guide rail 1121 is small enough to clamp the moving roller 111, the rolling of the moving roller 111 can be stopped. At this time, not only can the drawer body 120 be slowed down when it is pulled out, but the drawer body 120 can also be stopped from moving, reducing the risk of detachment.

[0042] As shown in Figure 3, the protrusion of the adjusting seat 1131 relative to the lower guide rail 1122 should not be too large, otherwise it will be difficult for the moving roller 111 to move between the adjusting seat 1131 and the upper guide rail 1121. In actual use, the adjusting seat 1131 is provided with a limiting end face, which can abut against the side wall of the lower guide rail 1122 away from the roller groove 1126 along the Z-axis direction, so as to limit the upward movement of the adjusting seat 1131 and prevent the size of the adjusting seat 1131 extending into the roller groove 1126 from being too large and affecting the passage of the moving roller 111.

[0043] As shown in Figures 2 and 6, furthermore, transition surfaces 1135 are provided on both sides of the adjusting seat 1131 along the length direction (i.e., the Y-axis direction) of the roller slide groove 1126. The transition surfaces 1135 facilitate the stable and smooth movement of the roller 111 to the adjusting seat 1131, reducing bumps during movement and protecting the items inside the drawer body 120. The transition surfaces 1135 can be arc-shaped or beveled; this is only an example.

[0044] Please refer to Figures 2 to 6. In some embodiments, the deceleration assembly 113 further includes a fixed seat 1133, which is disposed on the moving guide rail 112. The adjusting seat 1131 is slidably connected to the fixed seat 1133, and the elastic element 1132 abuts against the adjusting seat 1131 and the fixed seat 1133. That is, the fixed seat 1133 is used to connect the elastic element 1132 and the adjusting seat 1131 into an integral structure, which is then installed as a whole on the moving guide rail 112, making assembly more convenient. The fixed seat 1133 is provided with an assembly cavity, and the fixed seat 1133 has sliding grooves on both sides of the assembly cavity along the Y-axis direction. The adjusting seat 1131 extends into the corresponding sliding grooves on both sides along the Y-axis direction. The elastic element 1132 abuts against the lower part of the adjusting seat 1131, thereby causing the adjusting seat 1131 to float along the Z-axis direction. The sliding engagement between the adjusting seat 1131 and the fixed seat 1133 guides the floating of the adjusting seat 1131.

[0045] In practical use, the deceleration assembly 113 also includes a fastener 1139, which is connected to the fixed base 1133 and to the moving guide rail 112, thereby fixing the deceleration assembly 113 relative to the moving guide rail 112. The fastener 1139 can be a screw.

[0046] Among them, the elastic element 1132 can be a spring or a sheet.

[0047] Please refer to Figures 2 through 6. In some specific embodiments, the elastic element 1132 is a wave-shaped spring sheet with a crest section 1132a and a trough section 1132b. The crest section 1132a abuts against the adjusting seat 1131. The spring sheet also has straight sections 1132c on both sides along the Y-axis. The corresponding fixing seat 1133 has mounting bosses 1138 protruding on both sides along the Y-axis. Each straight section 1132c can be supported on a mounting boss 1138, thereby meeting the assembly requirements of the elastic element 1132 pressing against the adjusting seat 1131 and the fixing seat 1133, which is beneficial for the elastic element 1132 to apply force to the adjusting seat 1131.

[0048] Among them, there are at least two crest segments 1132a, which are arranged at intervals along the Y-axis direction, and a trough segment 1132b is connected between any two adjacent crest segments 1132a.

[0049] Please refer to Figures 2 through 6. In some embodiments, the deceleration assembly 113 further includes an adjusting member 1134. The adjusting member 1134 is movably connected to the fixed base 1133 and to the elastic member 1132. The adjusting member 1134 is used to tighten or loosen the elastic member 1132. That is, the adjusting member 1134 can be used to easily adjust the tightness of the elastic member 1132, thereby adjusting the magnitude of the force acting on the adjusting base 1131, and further adjusting the gap between the adjusting base 1131 and the upper guide rail 1121. This arrangement not only facilitates adjusting the friction between the adjusting base 1131 and the upper guide rail 1121 and the moving roller 111, but also facilitates adaptation to moving rollers 111 of different diameters, improving the flexibility of use.

[0050] In practical use, the adjusting member 1134 is connected to the trough section 1132b and is used to adjust the distance between the trough section 1132b and the adjusting seat 1131. The fixed seat 1133 has a threaded hole that connects to the assembly hole. The adjusting member 1134 passes through the threaded hole and is threaded to the wall of the threaded hole. The adjusting member 1134 uses a flat-head screw. Rotating the adjusting member 1134 can adjust the length of the adjusting member 1134 extending into the assembly cavity, thereby adjusting the pressing action on the spring piece. For example, rotating the adjusting member 1134 clockwise causes the adjusting member 1134 to screw into the fixed seat 1133, that is, the length of the adjusting member 1134 extending into the assembly cavity increases, thereby pushing the trough section 1132b upward, causing the distance between the trough section 1132b and the adjusting seat 1131 to decrease, increasing the elastic force of the spring piece on the adjusting seat 1131; thus, the adjusting seat 1131 can be moved closer to the upper guide rail 1121 to reduce the gap between the two. Conversely, rotating the adjusting component 1134 counterclockwise causes it to unscrew from the fixed seat 1133, reducing the length of the adjusting component 1134 extending into the assembly cavity. Consequently, the trough section 1132b is relaxed, increasing the distance between the trough section 1132b and the adjusting component 1134, and further increasing the gap between the adjusting seat 1131 and the upper guide rail 1121.

[0051] The trough section 1132b may have a circular hole for the adjusting member 1134 to pass through, and the adjusting member 1134 and the trough section 1132b are connected by a limiting protrusion protruding from the adjusting member 1134. Alternatively, the end of the adjusting member 1134 may directly abut against the lower surface of the trough section 1132b. This is only an example.

[0052] Referring to Figures 2 to 5, in some embodiments, the upper guide rail 1121 has a limiting portion 1124 on the side facing the roller groove 1126. The limiting portion 1124 can abut against the movable roller 111 to limit its displacement. That is, the limiting portion 1124 can constrain the movement range of the movable roller 111, thereby preventing the movable roller 111 from disengaging from the free side 112b of the moving guide rail 112 into the roller groove 1126. The end of the upper guide rail 1121 near the free side 112b can protrude towards the roller groove 1126 to form the limiting portion 1124. The movable roller 111 abuts against the limiting portion 1124 to satisfy the limiting function. Of course, the lower guide rail 1122 may have a limiting part 1124 protruding on the side facing the roller groove 1126, or the upper guide rail 1121 and the lower guide rail 1122 may both have a limiting part 1124 protruding on the opposite side. As long as it can satisfy the movement limitation of the moving roller 111 and prevent the moving roller 111 from leaving the roller groove 1126, it is acceptable.

[0053] Furthermore, the lower guide rail 1122 is provided with a groove 1128 that connects to the roller slide groove 1126 near the free side 112b. The groove 1128 can also be used to limit the movement of the roller 111, thereby preventing the roller 111 from disengaging from the roller slide groove 1126 and further improving the limiting effect.

[0054] The groove 1128 and the limiting part 1124 on the aforementioned upper guide rail 1121 can be arranged at intervals along the Y-axis direction. The limiting part 1124 serves as the primary limiting part for the moving roller 111, and the groove 1128 serves as the secondary limiting part for the moving roller 111. When the moving roller 111 moves to the groove 1128, the moving roller 111 is accommodated in the groove 1128 and abuts against the groove wall of the groove 1128 near the free side 112b, thereby achieving the limiting part.

[0055] As shown in Figure 2, in some specific embodiments, the movable guide rail 112 is provided with a limiting baffle 1127 on the positioning side 112a. The limiting baffle 1127 can abut against the movable roller 111 to limit the displacement of the movable roller 111 on the positioning side 112a and prevent the movable roller 111 from disengaging from the roller groove 1126. The limiting baffle 1127, the upper guide rail 1121, the lower guide rail 1122, and the integrated substrate 1125 can be integrally machined.

[0056] As shown in Figures 2 and 8, in some embodiments, the guide rail mechanism 110 further includes a slide roller 114, which is rotatably connected to the movable guide rail 112, and the slide roller 114 partially protrudes from the roller groove 1126. The slide roller 114 further improves the smoothness of the drawer body 120's pull-out. The slide roller 114 can be located below the drawer body 120 and roll in cooperation with the drawer body 120.

[0057] Multiple slide rollers 114 and multiple movable rollers 111 can be provided, such as two or three. The multiple slide rollers 114 are arranged at intervals along the Y-axis, and the multiple movable rollers 111 are also arranged at intervals along the Y-axis. Of course, only one of each can be provided. For example, the movable rollers 111 can be located on the rear side of the drawer body 120 along the Y-axis (i.e., the side closer to the positioning side 112a), and the slide rollers 114 can be located on the front side of the moving guide rail 112 along the Y-axis (i.e., the side closer to the free side 112b).

[0058] Please refer to Figures 1, 2, 7, 8, 9, and 10. In actual use, two movable guide rails 112 are provided, arranged opposite each other and spaced apart along the X-axis. Each movable guide rail 112 is equipped with a set of deceleration components 113 and at least one movable roller 111. Two movable rollers 111 opposite each other along the X-axis form a group, and the two movable rollers 111 are connected to a tray 130, which is used to connect to the drawer body 120. The tray 130 has an L-shaped connecting arm 131 on its rear side along the Y-axis. One side of the connecting arm 131 is fixed to the tray 130, and the other side is connected to the pivot of the movable roller 111. The tray 130 has a flange on its front side along the Y-axis, which can abut against the front side of the drawer body 120. A limiting component may be provided between the tray 130 and the drawer body 120. The limiting component includes a limiting block and a limiting hole. The limiting block is inserted into the limiting hole and protrudes from the bottom surface of the drawer body 120. The limiting hole is provided through the tray 130 to improve the connection reliability between the drawer body 120 and the tray 130.

[0059] Referring to Figures 11 and 12, this application also provides a refrigerator, including a cabinet 200, a refrigeration circuit 300, and the aforementioned storage drawers 100. The cabinet 200 has a first chamber 210, a second chamber 220, and a third chamber 230. Multiple storage drawers 100 are arranged vertically at intervals in the third chamber 230.
