[0001] The present invention relates to the technical field of furniture, in particular to a slide rail assembly. Background Art

[0002] Cabinets, shoe cabinets, etc. are essential household items in daily life. Most existing cabinets have fixed structures and the size of the cabinet space cannot be changed. People can only place a certain number of items according to the actual size of the cabinet. If there are too many items, they need to buy a new cabinet.

[0003] Telescopic and deformable furniture can effectively solve the above problems, but traditional hanging rails do not have the function of telescopic and deformable and cannot be used for telescopic and deformable furniture. Summary of the Invention

[0004] Based on this, it is necessary to provide a slide rail assembly to address the above technical problems.

[0005] A slide rail assembly, comprising:

[0006] The telescopic rod unit comprises a first rod body and a second rod body, wherein the first rod body is slidably connected to the second rod body;

[0007] a connecting unit comprising a first connecting member and a second connecting member, wherein the first connecting member is connected to the first rod body, and the second connecting member is connected to the second rod body; and

[0008] A hanging rail unit includes a first hanging rail and a second hanging rail, wherein the first hanging rail is connected to the first connecting member, and the second hanging rail is connected to the second connecting member;

[0009] When the first rod body slides relative to the second rod body, the first hanging rail is dragged to slide relative to the second hanging rail by the connecting unit, so that the slide rail assembly can be extended and retracted.

[0010] In one embodiment, the first rod body is sleeved with the second rod body, and when the slide rail assembly is extended to a fully expanded state, the first hanging rail and the second hanging rail are straightly connected and extend in the same direction; when the slide rail assembly is in a shortened state, the first hanging rail and the second hanging rail are stacked.

[0011] In one embodiment, the second connecting member includes a first fixing portion and a second fixing portion, the first fixing portion and the second fixing portion are slidingly arranged, the first fixing portion is connected to the second rod body, and the second fixing portion is connected to the second hanging rail.

[0012] In one embodiment, the first fixing part is provided with a guide groove, and a plurality of limit grooves are provided in the guide groove, and the plurality of limit grooves are arranged along the sliding direction of the first fixing part relative to the second fixing part, and the second fixing part is provided with a sliding pin slidably connected to the guide groove, and the sliding pin can slide from one limit groove into another adjacent limit groove when sliding along the guide groove.

[0013] In one embodiment, the slide rail assembly further includes a pulley unit, and the pulley unit connects the first hanging rail and the second hanging rail.

[0014] In one embodiment, the pulley unit includes a first pulley, a pulley bracket and a second pulley, and the first pulley and the second pulley are both connected to the pulley bracket; the first hanging rail is provided with a first slide groove, and the second hanging rail is provided with a second slide groove; the first pulley is slidably connected to the first slide groove, and the second pulley is slidably connected to the second slide groove.

[0015] In one embodiment, the first pulley is built into the first sliding groove, and the second pulley is built into the second sliding groove.

[0016] In one embodiment, the first hanging rail and the second hanging rail each include a first end and a second end, the first end is provided with a first guide surface, and the second end is provided with a second guide surface;

DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 As shown, Figure 1 Schematic diagram of the three-dimensional structure of a slide rail assembly 100 in one embodiment of the present application. The slide rail assembly 100 can be used on telescopic and deformable furniture. The telescopic and deformable furniture can be a cabinet 200, a shoe cabinet or a bookshelf, etc. The furniture can be extended and compressed in the horizontal direction, thereby changing the space size of the internal cavity of the furniture. Figure 4 As shown, Figure 4 This is a schematic diagram of a three-dimensional structure of a piece of furniture in one embodiment of the present application. Specifically, a cabinet 200 is used as an example to illustrate the furniture. The furniture includes Figure 1The slide rail assembly 100 shown. The furniture includes a first side wall 210, a second side wall 220, and the slide rail assembly 100 connecting the first side wall 210 and the second side wall 220. The slide rail assembly 100 can be extended and retracted in the horizontal direction, so that the first side wall 210 can move closer to or farther from the second side wall 220, thereby achieving the expansion and contraction of the furniture and changing the space size of the interior cavity of the furniture.

[0031] The specific structures of the slide rail assembly 100 and the furniture are introduced below respectively, and the specific structure of the furniture is introduced by taking the cabinet 200 as an example.

[0032] like Figure 1 As shown, the slide rail assembly 100 includes a telescopic rod unit 110, a connecting unit 120, and a hanging rail unit 130. The telescopic rod unit 110 serves as a support structure and acts as the skeleton of the entire slide rail assembly 100. The hanging rail unit 130 is connected to the telescopic rod unit 110 via the connecting unit 120. When the telescopic rod unit 110 moves, the connecting unit 120 drives the hanging rail unit 130 to move synchronously, thereby also allowing the hanging rail unit 130 to move.

[0033] The telescopic rod unit 110 includes a first rod 111 and a second rod 112, wherein the first rod 111 is slidably connected to the second rod 112. For example, the first rod 111 and the second rod 112 are both sleeve structures, and the second rod 112 can be inserted into the inner cavity of the first rod 111, thereby realizing the telescopic rod unit 110.

[0034] The connecting unit 120 includes a first connecting member 121 and a second connecting member 122. The first connecting member 121 is connected to the first rod 111, and the second connecting member 122 is connected to the second rod 112.

[0035] The hanging rail unit 130 includes a first hanging rail 131 and a second hanging rail 132 . The first hanging rail 131 is connected to the first connecting member 121 , and the second hanging rail 132 is connected to the second connecting member 122 .

[0036] Since the first connecting member 121 connects the first rod body 111 and the first hanging rail 131, and the second connecting member 122 connects the second rod body 112 and the second hanging rail 132, when the first rod body 111 slides relative to the second rod body 112, the first hanging rail 131 is dragged to slide relative to the second hanging rail 132 through the connecting unit 120.

[0037] like Figure 4As shown, a cabinet 200 is used as an example to illustrate furniture. The cabinet 200 includes a first side wall 210 and a second side wall 220, and a slide rail assembly 100 connecting the first side wall 210 and the second side wall 220. The first side wall 210 and the second side wall 220 are connected by the slide rail assembly 100, so the slide rail assembly 100 acts as a skeleton in the cabinet 200. Since the slide rail assembly 100 is retractable, the first side wall 210 and the second side wall 220 can move closer or further away. A cabinet cavity of the cabinet 200 is formed between the first side wall 210 and the second side wall 220. When the first side wall 210 and the second side wall 220 move closer, the cabinet cavity shrinks; when the first side wall 210 and the second side wall 220 move away, the cabinet cavity expands.

[0038] Specifically, the first side wall 210 is connected to the first rod 111, and the second side wall 220 is connected to the second rod 112. Since the telescopic rod unit 110 serves as a support and acts as the skeleton of the entire slide rail assembly 100, the hanging rail unit 130 does not need to be directly connected to the first side wall 210 and the second side wall 220. Of course, to enhance the structural strength of the entire cabinet 200, the first hanging rail 131 can also be connected to the first side wall 210, and the second hanging rail 132 can also be connected to the second side wall 220.

[0039] It should be noted that the slide rail assembly 100 in the above embodiment may further include a third rod body (not shown in the figure), and the first rod body 111, the second rod body 112 and the third rod body are slidably sleeved. The number of the third rod body can be selected according to actual needs. When the slide rail assembly 100 includes the third rod body, the connecting unit 120 also includes a third connecting member, and the hanging rail unit 130 also includes a third hanging rail, and the third hanging rail is connected to the third rod body through the third connecting member. In addition, when the slide rail assembly 100 includes the third rod body, the third connecting member and the third hanging rail, the assembly relationship between the third rod body, the third connecting member and the third hanging rail and other components can be adaptively changed according to the records of the embodiments of the present application, which will not be described in detail here.

[0040] like Figure 4 As shown, in addition to supporting the first side wall 210 and the second side wall 220, the slide rail assembly 100 also serves to connect the folding door 240 of the cabinet 200. The folding door 240 includes a plurality of door panels 241 connected in sequence, and each door panel 241 is connected to the hanging rail unit 130. For example, each door panel 241 is provided with a sliding member, which can be a sliding pin or a sliding wheel. Figure 1As shown, the first hanging rail 131 and the second hanging rail 132 are both provided with hanging grooves 133, and the sliding member is suspended in the hanging grooves 133 and can slide along the hanging grooves 133. When the slide rail assembly 100 is extended to a fully deployed state, the first hanging rail 131 and the second hanging rail 132 are aligned and extend in the same direction, so that the sliding member can slide from the hanging groove 133 of the first hanging rail 131 to the hanging groove 133 of the second hanging rail 132. Of course, further, when the first hanging rail 131 and the second hanging rail 132 extend in the same direction, the hanging groove 133 of the first hanging rail 131 and the hanging groove 133 of the second hanging rail 132 are aligned, which allows the sliding member to transfer between the hanging grooves 133 of the first hanging rail 131 and the hanging groove 133 of the second hanging rail 132 more smoothly, without the sliding member being stuck at the position where adjacent hanging grooves 133 are aligned due to poor alignment of adjacent hanging grooves 133.

[0041] like Figure 2 As shown, Figure 2 for Figure 1 The slide rail assembly 100 is shown in a schematic structural diagram in a shortened state. When the slide rail assembly 100 is shortened, the first hanging rail 131 and the second hanging rail 132 are in a stacked state. Figure 2 In the illustrated embodiment, the second hanging rail 132 is stacked above the first hanging rail 131. Therefore, when the cabinet 200 needs to be moved from the expanded state to the shortened state, the folding door 240 needs to be folded first, and the sliding members of the door leaf 241 need to be completely slid into the hanging groove 133 of the first hanging rail 131.

[0042] like Figure 2 As shown, when the slide rail assembly 100 is in the shortened state, the first hanging rail 131 and the second hanging rail 132 are stacked, with the second hanging rail 132 stacked above the first hanging rail 131. Since the first connecting member 121 connects the first hanging rail 131 and the first rod 111, and the second connecting member 122 connects the second hanging rail 132 and the second rod 112, at least the second connecting member 122 can extend and retract in the vertical direction. Figure 3This is a schematic diagram of the structure of the connection unit 120 in one embodiment of the present application. Specifically, taking the second connection member 122 as an example, the second connection member 122 includes a first fixing portion 120A and a second fixing portion 120B. The first fixing portion 120A and the second fixing portion 120B are slidably arranged along the telescopic direction shown in the figure, and the telescopic direction shown in the figure is perpendicular to the telescopic direction of the telescopic rod unit 110. The first fixing portion 120A is U-shaped and is connected to the second rod body 112 in the telescopic rod unit 110. There are two second fixing portions 120B, which are respectively connected to the two ends of the U-shaped first fixing portion 120A. Furthermore, the second fixing portion 120B is connected to the second hanging rail 132 of the hanging rail unit 130. In some embodiments, the first connecting member 121 can also be extended and retracted along the vertical direction. For example, the first connecting member 121 includes a first fixed portion 120A and a second fixed portion 120B. The first fixed portion 120A and the second fixed portion 120B are slidingly arranged along the extension direction shown in the figure. The first fixed portion 120A is connected to the first rod body 111 of the telescopic rod unit 110, and the second fixed portion 120B is connected to the first hanging rail 131 of the hanging rail unit 130.

[0043] It should be understood that if Figure 2 As shown, the second hanging rail 132 is stacked above the first hanging rail 131. When the slide rail assembly 100 changes from a fully extended state to a shortened state, the second hanging rail 132 moves above the first hanging rail 131. Therefore, the distance between the first hanging rail 131 and the first rod 111 does not need to be changed, and the first connecting member 121 does not need to be configured as a retractable structure. The first connecting member 121 can be configured as a fixed seat with one end connected to the first hanging rail 131 and the other end connected to the first rod 111.

[0044] Continue reading Figure 3 When the first connecting member 121 and the second connecting member 122 are telescopic structures, the first fixed part 120A is provided with a guide groove 120A1, and a plurality of limit grooves 120A2 are provided in the guide groove 120A1. These limit grooves 120A2 can all be semicircular. These limit grooves 120A2 are arranged along the sliding direction of the first fixed part 120A and the second fixed part 120B. The second fixed part 120B is provided with a sliding pin 120B1 that is slidably connected to the guide groove 120A1. When the sliding pin 120B1 slides along the guide groove 120A1, it can be embedded in different limit grooves 120A2. It should be understood that when the sliding pin 120B1 is embedded in and matched with a certain limit groove 120A2, the limit groove 120A2 can play a role in limiting or positioning the sliding pin 120B1. When it is necessary to transfer the sliding pin 120B1 between different limit grooves 120A2, just move it along the guide groove 120A1. Figure 3 The first fixing portion 120A and the second fixing portion 120B can be squeezed in the extension and contraction direction shown.

[0045] like Figure 2 As shown, the slide rail assembly 100 may further include a pulley unit 140 that connects the first hanging rail 131 and the second hanging rail 132. When the slide rail assembly 100 is extended to a fully deployed state, the first hanging rail 131 and the second hanging rail 132 extend in the same direction. When the slide rail assembly 100 is shortened from the fully deployed state, the second hanging rail 132 moves above the first hanging rail 131. The provision of the pulley unit 140 allows for smoother movement of the second hanging rail 132 relative to the first hanging rail 131.

[0046] Specifically, if Figure 2 As shown, the pulley unit 140 may include a first pulley 141, a pulley bracket 143, and a second pulley 142. The first pulley 141 and the second pulley 142 are both connected to the pulley bracket 143. The first hanging rail 131 is provided with a first slide groove 131A, and the second hanging rail 132 is provided with a second slide groove 132A. The first pulley 141 is slidably connected to the first slide groove 131A, and the second pulley 142 is slidably connected to the second slide groove 132A. The first slide groove 131A is used to guide the sliding of the first pulley 141, and the second slide groove 132A is used to guide the sliding of the second pulley 142. Therefore, when the first hanging rail 131 and the second hanging rail 132 are connected by the pulley unit 140, when the second hanging rail 132 slides relative to the first hanging rail 131, it can be guided by the first slide groove 131A and the second slide groove 132A, preventing the first hanging rail 131 and the second hanging rail 132 from misaligning.

[0047] In one embodiment, the first pulley 141 can be built into the first chute 131A, and the second pulley 142 can be built into the second chute 132A. "Built-in" here does not mean that the first pulley 141 is entirely disposed in the first chute 131A, and the second pulley 142 is entirely disposed in the second chute 132A; rather, "buil-in" means that during normal use of the rail assembly 100, the first pulley 141 cannot disengage from the first chute 131A, and the second pulley 142 cannot disengage from the second chute 132A. Specifically, the first pulley 141 can be rotatably connected to the pulley bracket 143 via a connecting shaft, and the second pulley 142 can be rotatably connected to the pulley bracket 143 via another connecting shaft. The connecting shaft connecting the first pulley 141 and the pulley bracket 143 has two protruding ends that slide and engage the inner walls of the first chute 131A, allowing the first pulley 141 to slide along the first chute 131A but preventing it from disengaging from the first chute 131A. Similarly, the ends of the connecting shaft connecting the second pulley 142 to the pulley bracket 143 protrude outward, and the ends of the connecting shaft are clamped on the two inner walls of the second slide groove 132A, so that the second pulley 142 can slide along the second slide groove 132A but cannot escape from the first slide groove 131A. This arrangement ensures the stability of the connection between the pulley unit 140 and the first and second hanging rails 131, 132.

[0048] like Figure 1 As shown, the first hanging rail 131 and the second hanging rail 132 each include a first end 130A and a second end 130B. When the slide rail assembly 100 is extended to a fully expanded state, the second end 130B of the first hanging rail 131 docks with the first end 130A of the second hanging rail 132. Figure 2 As shown, the first end 130A is provided with a first guide surface 130A1, and the second end 130B is provided with a second guide surface 130B1. Figure 1 As shown, when the slide rail assembly 100 is extended to the fully expanded state, a portion of the second guide surface 130B1 of the first hanging rail 131 is in contact with a portion of the first guide surface 130A1 of the second hanging rail 132. Figure 2 As shown, when the slide rail assembly 100 changes from the fully extended state to the shortened state, the first guide surface 130A1 of the second hanging rail 132 slides along the second guide surface 130B1 of the first hanging rail 131, so that the first hanging rail 131 and the second hanging rail 132 are stacked, and the second hanging rail 132 is located above the first hanging rail 131. When the first hanging rail 131 and the second hanging rail 132 slide relative to each other, that is, when the slide rail assembly 100 changes from the fully extended state to the shortened state, or when the slide rail assembly 100 changes from the shortened state to the fully extended state, the first guide surface 130A1 and the second guide surface 130B1 abut against each other, making the sliding process of the first hanging rail 131 and the second hanging rail 132 smoother.

[0049] Continue reading Figure 2 The first guide surface 130A1 includes a first convex curved surface 130A11 and a plane 130A12 connecting the first convex curved surface 130A11. When the slide rail assembly 100 transitions from a fully extended state to a shortened state, the first convex curved surface 130A11 slides along the second guide surface 130B1, causing the first hanging rail 131 and the second hanging rail 132 to be stacked. The second guide surface 130B1 includes a concave curved surface 130B11 and a second convex curved surface 130B12 connecting the concave curved surface 130B11. When the slide rail assembly 100 transitions from a fully extended state to a shortened state, the first convex curved surface 130A11 slides successively along the concave curved surface 130B11 and the second convex curved surface 130B12, causing the first hanging rail 131 and the second hanging rail 132 to be stacked.

[0050] The following continues to introduce the furniture in this application using cabinet 200 as an example. Figure 4 As shown, the furniture also includes a base unit 230, which includes a plurality of slidably connected unit panels 231. When the base unit 230 is deployed, the unit panels 231 at the left and right ends are respectively connected to the first side wall 210 and the second side wall 220. For example, if the second side wall 220 is pushed leftward, bringing it closer to the first side wall 210, the unit panel 231 connected to the second side wall 220 will also begin to move toward the unit panel 231 connected to the first side wall 210. The unit panels 231 of the base unit 230 are stacked, allowing the base unit 230 composed of these unit panels 231 to be extended and retracted.

[0051] like Figure 4 As shown, the cabinet 200 further includes a soft film rolling curtain 250 disposed on the opposite side of the bottom plate unit 230. When the cabinet 200 is normally placed, the bottom plate unit 230 is located at the bottom and the soft film rolling curtain 250 is located at the top. Figure 6The soft film roll-up blind 250 includes a reel 251 and a blind body 252 wound around the reel 251. The reel 251 is rotatably connected to the first side wall 210, while the free end of the blind body 252 is connected to the second side wall 220. The free end of the blind body 252 refers to the end of the blind body 252 not connected to the reel 251. When the first side wall 210 and the second side wall 220 move away from each other, the second side wall 220 pulls the free end of the blind body 252, gradually separating the blind body 252 from the reel 251. Furthermore, the reel 251 has an automatic rewinding function. For example, a torsion spring can be installed between the reel 251 and the first side wall 210. When the first side wall 210 and the second side wall 220 move closer together, the elastic force of the torsion spring drives the reel 251 to rotate about its rotation axis, causing the blind body 252 to rewind around the reel 251. Of course, in other embodiments, the roller 251 can also be rotatably mounted on the second side wall 220, and the free end of the roller blind body 252 can be mounted on the first side wall 210. In some embodiments, the soft film roller blind 250 is provided with an LED light source, so that the soft film roller blind 250 can realize a lighting function to provide supplementary light for the interior of the cabinet 200.

[0052] like Figure 5 As shown, Figure 5 A perspective view of a piece of furniture in one embodiment of the present application, in combination with Figure 4 and Figure 5 The furniture also includes a telescopic clothes rod 270. The telescopic clothes rod 270 includes a first rod portion 271 and a second rod portion 272 that are slidably connected. The first rod portion 271 is connected to the first side wall 210, and the second rod portion 272 is connected to the second side wall 220. When the first side wall 210 and the second side wall 220 move closer or further away, the telescopic clothes rod 270 can also extend or contract accordingly.

[0053] Furthermore, if Figure 4 As shown, the furniture also includes a telescopic trouser rack 260. The telescopic trouser rack 260 includes a first foldable telescopic bracket 261, a second foldable telescopic bracket 262, and a plurality of support rods 263. Both the first and second foldable telescopic brackets 261 and 262 are wavy in shape. The first and second side walls 210 and 220 are connected at their ends, respectively, while the second and second side walls 210 and 220 are connected at their ends. When the first and second side walls 210 and 220 move closer together, the wavy shape compresses. When the first and second side walls 210 and 220 move away from each other, the wavy shape stretches. The support rods 263 are connected at their ends, respectively, to the first and second foldable telescopic brackets 261 and 262. The distance between the support rods 263 increases when the first and second side walls 210 and 220 move away from each other, and decreases when the first and second side walls 210 and 220 move closer together.

[0054] Figure 6 This is a schematic diagram of a certain state of the furniture shortening process in one embodiment of the present application. Figure 7 This is a schematic diagram of the fully extended state of furniture in one embodiment of the present application. The telescopic rod unit 110 in the slide rail assembly 100 of the furniture includes at least a first rod 111 and a second rod 112, and may also include a third rod. The number of third rods can be selected based on actual needs. When the slide rail assembly 100 includes a third rod, the connection unit 120 also includes a third connector, and the hanging rail unit 130 also includes a third hanging rail, which is connected to the third rod via the third connector. The number of third hanging rails and third connectors can also be selected based on actual needs.

[0055] like Figure 7 As shown, when the furniture is fully unfolded, the first hanging rail 131, the second hanging rail 132 and the third hanging rail in the hanging rail unit 130 extend in the same direction. And the center axis of the first pulley 141 and the center axis of the second pulley 142 in the pulley unit 140 are on the same horizontal straight line. The concave arc surface 130B11 of the first hanging rail 131 fits with the first convex arc surface 130A11 of the second hanging rail 132, and there is a certain gap between the second convex arc surface 130B12 of the first hanging rail 131 and the plane 130A12 of the second hanging rail 132. When the furniture changes from a fully unfolded state to a compressed state, the first convex arc surface 130A11 of the second hanging rail 132 gradually slides to the top of the first hanging rail 131 along the concave arc surface 130B11 and the second convex arc surface 130B12 of the second hanging rail 132, as shown in FIG. Figure 6 As shown, at this time, the central axis of the first pulley 141 and the central axis of the second pulley 142 in the pulley unit 140 are on the same vertical line.
