Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and more particularly to a slide rail device, a cabinet assembly, and a refrigerator. Background Technology

[0002] Refrigerators, as containers that keep food or other items at a constant low temperature, have become an indispensable household appliance in modern homes. A refrigerator typically includes a separate refrigerator compartment and a freezer compartment, used to store items that need to be stored at different temperatures. For convenient placement of certain items, the refrigerator and freezer compartments usually have pull-out shelves.

[0003] In related technologies, for upward-pull-out cabinet structures, the lack of corresponding limiting mechanisms causes the cabinet to easily slide relative to the inner liner under gravity, preventing the cabinet from staying at the target position and reducing the user experience. Utility Model Content

[0004] This application provides a slide rail device in which the guide rail base and guide rail bracket will not slide relative to each other under the action of gravity, so that the box can be stopped in the required position, and the user experience is better.

[0005] This application also provides a housing assembly.

[0006] This application also provides a refrigerator.

[0007] The slide rail device of this application includes: a guide rail base extending along a first direction, the guide rail base having a first wall surface along a second direction, the first direction being orthogonal to the second direction; a guide rail bracket slidably connected to the guide rail base along the first direction; and a limiting component including a limiting member and a first elastic member, the limiting member being switchable between a released state and a locked state, in the locked state the limiting member being spaced apart from the first wall surface, and in the released state the first elastic member pressing the limiting member toward the first wall surface, the limiting member being movable relative to the guide rail bracket along the second direction and abutting against the first wall surface.

[0008] According to the slide rail device of the embodiment of this application, since the limiting member can switch between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, thereby allowing the guide rail bracket and the guide rail seat to slide freely, so as to avoid the problem of jamming when the guide rail bracket and the guide rail seat slide. Since the first elastic member presses the limiting member in the direction toward the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Therefore, under the action of the elastic force of the first elastic member, the relative movement of the guide rail bracket and the guide rail seat can be constrained, so as to avoid the problem of the guide rail bracket moving relative to the guide rail seat under the action of gravity. This allows the box to be stopped in the required position, improving the user experience.

[0009] In some embodiments, the first wall surface is provided with a plurality of positioning grooves, the plurality of positioning grooves are arranged at intervals along the first direction, the guide rail seat has a first end and a second end arranged opposite to each other along the first direction, and when the guide rail bracket moves along the direction from the first end to the second end, the limiting member is in a released state so that the limiting member extends into different positioning grooves.

[0010] In some embodiments, the limiting member has a first stop surface arranged toward the second end. In the direction from the first end to the second end, the first stop surface extends obliquely away from the first wall surface. When the guide rail bracket moves in the direction from the first end to the second end, the first stop surface can slide relative to the outer edge of the positioning groove so that the limiting member can disengage from the positioning groove.

[0011] In some embodiments, the limiting member has a second stop surface arranged toward the first end, and the second stop surface can abut against the inner wall surface of the positioning groove to restrict the limiting member from disengaging from the positioning groove in the direction from the second end to the first end.

[0012] In some embodiments, the guide rail base has a first end and a second end arranged opposite to each other along a first direction. The limiting assembly further includes a main shell and a locking component. The main shell is disposed on the guide rail base. The limiting component and the locking component are both connected to the main shell. When the main shell moves to the second end, the locking component can restrict the movement of the limiting component to switch the limiting component to a locked state. When the main shell moves to the first end, the locking component and the limiting component can move relative to each other to switch the limiting component to a released state.

[0013] In some embodiments, the first wall surface is provided with a protrusion, which is arranged near the second end. When the main shell moves to the second end, the limiting member can move in a direction away from the first wall surface under the guidance of the protrusion to switch the limiting member to a locked state.

[0014] In some embodiments, the locking component includes a guide frame and a second elastic member. The guide frame is slidably mounted on the main housing along the first direction. The second elastic member presses the guide frame along the direction toward the first end. The guide frame has a first mating portion on the side toward the second end. The limiting member has a second mating portion. In the locked state, the first mating portion and the second mating portion are aligned and engaged. In the released state, the first mating portion and the second mating portion are spaced apart along the second direction.

[0015] In some embodiments, one of the first mating portion and the second mating portion is a stop bar, and the other is a groove. In the locked state, the stop bar is engaged with the groove, and in the released state, the stop bar and the groove are spaced apart along the second direction.

[0016] In some embodiments, the main shell is provided with first slide rails on both sides along a third direction, the first direction, the second direction and the third direction are orthogonal to each other, the guide frame includes two first guide rods, the two first guide rods are arranged on both sides of the main shell along the third direction and slide in cooperation with the first slide rails, the stop rods are respectively connected to the two first guide rods, and the groove is provided on the limiting member.

[0017] In some embodiments, the guide frame is provided with a third mating part on the side facing the first end, and the first end of the guide rail seat is provided with a stop plate. When the third mating part presses the stop plate in the direction from the second end to the first end, the first mating part and the second mating part are spaced apart in the second direction to release the limiting member.

[0018] In some embodiments, the main housing is provided with a second slide rail, the limiting member has a second guide rod, the second guide rod slides through the second slide rail in the second direction; and / or, one end of the first elastic member abuts against the limiting member, and the other end of the first elastic member abuts against the main housing.

[0019] In some embodiments, one of the main housing and the guide rail bracket is provided with a first snap-fit ​​portion and the other is provided with a first snap-fit ​​groove, wherein the first snap-fit ​​portion snaps into the first snap-fit ​​groove; and / or, the limiting component further includes a first fastener, wherein the first fastener passes through the main housing and the guide rail bracket.

[0020] In some embodiments, the slide rail device further includes a roller, which is rotatably mounted on the guide rail bracket, and the outer wall surface of the roller abuts against the guide rail seat.

[0021] Another embodiment of the box assembly of this application includes: a box liner, a box body, and a slide rail device. The slide rail device is the slide rail device described in any one of the embodiments of this application. The box body is removably installed inside the box liner. The guide rail seat is connected to the box liner. The guide rail bracket is connected to the box body. Both the guide rail seat and the guide rail bracket extend upwardly in a direction from the front side to the rear side of the box body.

[0022] According to the embodiment of the present application, the housing assembly is switchable between a released state and a locked state. In the locked state, the limiting member is spaced apart from the first wall surface, thereby allowing the guide rail bracket and the guide rail seat to slide freely, thus avoiding the problem of jamming when the guide rail bracket and the guide rail seat slide. Since the first elastic member presses the limiting member in the direction toward the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Thus, under the action of the elastic force of the first elastic member, the relative movement of the guide rail bracket and the guide rail seat can be constrained, thus avoiding the problem of the guide rail bracket moving relative to the guide rail seat under the action of gravity. This allows the housing to be stopped in the required position, improving the user experience.

[0023] Another embodiment of the refrigerator of this application includes the cabinet assembly described in the embodiments of this application.

[0024] According to the refrigerator of the embodiment of this application, since the limiting member can switch between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, thereby allowing the guide rail bracket and the guide rail seat to slide freely, so as to avoid the problem of jamming when the guide rail bracket and the guide rail seat slide. Since the first elastic member presses the limiting member in the direction toward the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Therefore, under the action of the elastic force of the first elastic member, the relative movement of the guide rail bracket and the guide rail seat can be constrained, so as to avoid the problem of the guide rail bracket moving relative to the guide rail seat under the action of gravity. This allows the refrigerator to be stopped in the required position, improving the user experience. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0051] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0052] The following is a reference appendix. Figures 1 to 15 This application describes a slide rail device, a cabinet assembly, and a refrigerator according to embodiments of the present application.

[0053] like Figures 1 to 4 As shown, the slide rail device of this application embodiment includes: a guide rail base 1, a guide rail bracket 2, and a limiting component 3. The guide rail base 1 is positioned along a first direction (e.g., ...). Figure 2 Extending in the front-back direction, the guide rail seat 1 extends along the second direction (such as...). Figure 2 A first wall 13 is provided in the left and right directions. The first direction is orthogonal to the second direction. The guide rail bracket 2 is slidably connected to the guide rail seat 1 along the first direction.

[0054] The limiting component 3 includes a limiting member 31 and a first elastic member 32. The limiting member 31 can be switched between a released state and a locked state. In the locked state, the limiting member 31 is spaced apart from the first wall surface 13. In the released state, the first elastic member 32 presses the limiting member 31 toward the first wall surface 13. The limiting member 31 can move relative to the guide rail bracket 2 along the second direction and abuts against the first wall surface 13.

[0055] According to the slide rail device of the embodiment of this application, since the limiting member 31 can switch between a released state and a locked state, in the locked state, the limiting member 31 is spaced apart from the first wall surface 13, thereby allowing the guide rail bracket 2 and the guide rail seat 1 to slide freely, so as to avoid the problem of jamming when the guide rail bracket 2 and the guide rail seat 1 slide. Since the first elastic member 32 presses the limiting member 31 in the direction of the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thus, under the action of the elastic force of the first elastic member 32, the relative movement of the guide rail bracket 2 and the guide rail seat 1 can be constrained, so as to avoid the problem of the guide rail bracket 2 moving relative to the guide rail seat 1 under the action of gravity. Thus, the box 5 can be stopped in the required position, improving the user experience.

[0056] like Figure 2 As shown, the guide rail bracket 2 is used to be installed on the box 5. When the user pulls out the box 5, the guide rail bracket 2 can slide relative to the guide rail seat 1 in the first direction.

[0057] like Figure 2 and Figure 3 As shown, the slide rail device is arranged at an upward angle from front to back. When the box 5 is pulled upward at an angle from front to back, due to the weight of the box 5, the box 5 will exert a downward force on the guide rail bracket 2 under the action of gravity. Since the limiting member 31 can move relative to the guide rail bracket 2 in the second direction when it is released, and the limiting member 31 abuts against the first wall surface 13, the guide rail bracket 2 will not slide downward due to the gravity of the box 5 under the cooperation of the limiting member 31 and the first wall surface 13. Thus, the box 5 can be stopped in the position required by the user, thereby improving the user experience.

[0058] Optionally, such as Figure 7 and Figure 12 As shown, the first wall surface 13 is provided with a plurality of positioning grooves 131, which are arranged at intervals along the first direction. The guide rail seat 1 has a first end 11 and a second end 12 arranged opposite to each other along the first direction. When the guide rail bracket 2 moves along the direction from the first end 11 to the second end 12, the limiting member 31 is in a released state so that the limiting member 31 can extend into different positioning grooves 131.

[0059] like Figure 2As shown, the first end 11 is the rear end of the guide rail seat 1, and the second end 12 is the front end of the guide rail seat 1. That is to say, the front-back direction of the guide rail seat 1 is consistent with the front-back direction when the refrigerator is actually in use. When the guide rail bracket 2 moves in the direction from back to front, the limiting member 31 is in the released state so that the limiting member 31 can extend into different positioning grooves 131, thereby fixing the sliding position of the guide rail bracket 2, further preventing the guide rail bracket 2 from sliding downward under the gravity of the cabinet 5, which helps to improve the stability of the guide rail bracket 2 when it is stationary.

[0060] It should be noted that the number of positioning slots 131 can be two, three or more, and this application does not limit this.

[0061] Optionally, such as Figure 10 and Figure 14 As shown, the limiting member 31 has a first stop surface 311, which is arranged toward the second end 12. In the direction from the first end 11 to the second end 12, the first stop surface 311 extends obliquely away from the first wall surface 13. When the guide rail bracket 2 moves in the direction from the first end 11 to the second end 12, the first stop surface 311 can slide relative to the outer edge of the positioning groove 131 so that the limiting member 31 can disengage from the positioning groove 131.

[0062] It is understandable that the first stop surface 311 is an inclined surface. When the guide rail bracket 2 moves along the direction from the first end 11 to the second end 12, since the limiting member 31 is movable relative to the guide rail bracket 2 along the second direction, under the guiding action of the first stop surface 311, the limiting member 31 can gradually retract and disengage from the positioning groove 131. Thus, when the user moves along the direction from the first end 11 to the second end 12 (e.g., ... Figure 2 When the guide rail bracket 2 is pulled out from back to front, the positioning groove 131 neither restricts the movement of the guide rail bracket 2 along the direction from the first end 11 to the second end 12, but also temporarily locks the guide rail bracket 2, greatly reducing the movement of the guide rail bracket 2 along the direction from the second end 12 to the first end 11 under the action of gravity (e.g., from back to front). Figure 2 The problem of retraction (from front to back) can be solved, thus enabling the box 5 to stay stably in different positions.

[0063] Optionally, such as Figure 10 and Figure 14 As shown, the limiting member 31 has a second stop surface 312. The limiting member 31 includes the second stop surface 312, which is arranged facing the first end 11. The second stop surface 312 can abut against the inner wall surface of the positioning groove 131 to restrict the limiting member 31 from disengaging from the positioning groove 131 in the direction from the second end 12 to the first end 11. It can be understood that when the guide rail bracket 2 has a direction from the second end 12 to the first end 11 (e.g., Figure 2When the guide rail bracket 2 moves from front to back, the second stop surface 312 can abut against the inner wall of the positioning groove 131, thereby preventing the guide rail bracket 2 from retracting along the direction from the second end 12 to the first end 11, thus improving the stability of the box 5 when it stays at the target position.

[0064] For example, the plane containing the second stop surface 312 is orthogonal to the first direction to improve the stopping effect of the second stop surface 312.

[0065] Optionally, such as Figure 2 and Figure 6 As shown, the guide rail base 1 has a first end 11 and a second end 12 arranged opposite to each other along a first direction. The limiting component 3 also includes a main shell 33 and a locking component 34. The main shell 33 is disposed on the guide rail base 1. The limiting component 31 and the locking component 34 are both connected to the main shell 33. When the main shell 33 moves to the second end 12, the locking component 34 can restrict the movement of the limiting component 31 to switch the limiting component 31 to the locked state. When the main shell 33 moves to the first end 11, the locking component 34 and the limiting component 31 can move relative to each other to switch the limiting component 31 to the released state.

[0066] It is understandable that, such as Figure 14 As shown, when the guide rail bracket 2 moves the main shell 33 toward the second end 12, until the main shell 33 moves to the limit position of the second end 12, the locking component 34 can lock the limiting component 31. At this time, the limiting component 31 is in a locked state, that is, the limiting component 31 cannot move in the second direction, and the limiting component 31 is spaced apart from the first wall surface 13. Therefore, when the guide rail bracket 2 moves from the second end 12 to the first end 11, the limiting component 31 will not collide or interfere with the guide rail seat 1, thus ensuring that the guide rail bracket 2 can be smoothly reset, that is, the box 5 retracts into the box liner.

[0067] When the guide rail bracket 2 moves the main housing 33 toward the first end 11, until the main housing 33 reaches the limit position of the first end 11, the locking component 34 can release the limiting component 31. At this time, the limiting component 31 is in a released state, thus preparing for the next extraction of the guide rail bracket 2. Therefore, the slide rail device of this application, by setting the limiting component 3 to the above structure, can improve the linkage effect between the limiting component 31 and the locking component 34, and the operation process is smooth and convenient for users.

[0068] Optionally, such as Figure 12 and Figure 15As shown, the first wall surface 13 is provided with a protrusion 132, which is arranged near the second end 12. When the main shell 33 moves to the second end 12, the limiting member 31 can move away from the first wall surface 13 under the guidance of the protrusion 132, so as to switch the limiting member 31 to the locked state. It can be understood that when the main shell 33 moves to the second end 12 with the guide rail bracket 2, the limiting member 31 can move away from the first wall surface 13 under the guidance of the protrusion 132, so that the first wall surface 13 and the limiting member 31 are separated. At this time, the locking member 34 locks the limiting member 31, so that the limiting member 31 is switched to the locked state. The slide rail device of the embodiment of this application, by providing the protrusion 132, can automatically separate the limiting member 31 from the first wall surface 13 when the guide rail bracket 2 is pulled forward to the limit position, and does not require a drive source such as a motor to drive it, which helps to reduce the production cost of the slide rail device, and the structure design is simple and the operation is reliable.

[0069] For example, such as Figure 12 As shown, the protrusion 132 has a guide slope 1321. The first stop surface 311 and the guide slope 1321 can slide in a surface contact manner to avoid jamming when the limiting member 31 contacts the protrusion 132.

[0070] Optionally, such as Figures 7 to 10 As shown, the locking component 34 includes a guide frame 341 and a second elastic member 342. The guide frame 341 is slidably mounted on the main housing 33 along a first direction. The second elastic member 342 presses the guide frame 341 along the direction toward the first end 11. The guide frame 341 has a first mating part 3411 on the side toward the second end 12. The limiting member 31 has a second mating part 313. In the locked state, the first mating part 3411 and the second mating part 313 are aligned and engaged. In the released state, the first mating part 3411 and the second mating part 313 are spaced apart along a second direction.

[0071] like Figure 14 As shown, when the guide rail bracket 2 drives the main shell 33 to move toward the second end 12, until the main shell 33 moves to the limit position of the second end 12, the limiting member 31 can move toward the direction away from the first wall surface 13 under the guidance of the protrusion 132, thereby aligning and engaging the first mating part 3411 and the second mating part 313 so that the limiting member 31 is in a locked state.

[0072] like Figure 13 As shown, when the guide rail bracket 2 drives the main shell 33 to move toward the first end 11, until the main shell 33 moves to the limit position of the first end 11, the first mating part 3411 and the second mating part 313 can be spaced apart along the second direction to unlock the limiting member 31, thereby preparing for the next extraction of the guide rail bracket 2.

[0073] The slide rail device of this application, by adopting the above-described structure for the locking component 34, enables the guide rail bracket 2 to automatically switch the state of the limiting component 31 when it is pulled to the limit position, thereby improving the linkage effect between the limiting component 31 and the locking component 34. The structure is reasonably designed and has a good performance.

[0074] Optionally, such as Figure 7 and Figure 10 As shown, one of the first mating part 3411 and the second mating part 313 is a stop rod 34111, and the other is a groove 3131. In the locked state, the stop rod 34111 is engaged with the groove 3131. In the released state, the stop rod 34111 and the groove 3131 are spaced apart along the second direction. It should be noted that when the limiting member 31 is in the released state, whether the limiting member 31 is abutting against the first wall surface 13 or the limiting member 31 is extended into the positioning groove 131, the stop rod 34111 and the groove 3131 are spaced apart along the second direction.

[0075] For example, the first mating part 3411 is a stop bar 34111, and the second mating part 313 is a groove 3131. When the stop bar 34111 engages with the groove 3131, the position of the limiting member 31 can be locked to restrict the movement of the limiting member 31 in the second direction, thereby allowing the guide rail bracket 2 to retract unimpeded to the first end 11. The slide rail device of the embodiment of this application, by adopting the above-described structural arrangement of the first mating part 3411 and the second mating part 313, facilitates the processing and manufacturing of the first mating part 3411 and the second mating part 313, and ensures reliable operation.

[0076] For example, such as Figure 7 and Figure 10 As shown, the groove 3131 is a semi-cylindrical groove, and the cross-sectional profile of the stop rod 34111 is circular, which can improve the smoothness of the stop rod 34111 when it is disengaged from or inserted into the groove 3131.

[0077] Optionally, such as Figure 7 and Figure 11 As shown, the main shell 33 has first slide rails 331 on both sides along the third direction. The first direction, the second direction, and the third direction are orthogonal to each other. The guide frame 341 includes two first guide rods 3412, which are arranged on both sides of the main shell 33 along the third direction and slide in cooperation with the first slide rails 331. Stop rods 34111 are connected to the two first guide rods 3412 respectively. The groove 3131 is provided on the limiting member 31. It can be understood that the first guide rods 3412 can slide within the first slide rails 331. The first slide rails 331 can provide positional constraints for the sliding of the guide frame 341 to improve the stability of the guide frame 341 during sliding.

[0078] One end of the second elastic member 342 along the first direction abuts against the main shell 33, and the other end of the second elastic member 342 along the first direction abuts against the guide frame 341. The second elastic member 342 presses against the guide frame 341 in the direction toward the first end 11, so that there is an elastic contact force between the stop rod 34111 and the limiting member 31. It should be noted that the elastic force of the second elastic member 342 is greater than the elastic force of the first elastic member 32. When the stop rod 34111 is inserted into the groove 3131, the elastic force of the first elastic member 32 will not drive the groove 3131 to disengage from the stop rod 34111.

[0079] Optionally, such as Figure 8 and Figure 10 As shown, the guide frame 341 has a third mating part 3413 on the side facing the first end 11, and the first end 11 of the guide rail seat 1 has a stop plate 14. When the third mating part 3413 presses the stop plate 14 in the direction from the second end 12 to the first end 11, the first mating part 3411 and the second mating part 313 are spaced apart in the second direction to release the limiting member 31.

[0080] When the guide rail bracket 2 drives the main shell 33 to move toward the first end 11, until the main shell 33 moves to the limit position of the first end 11, the third mating part 3413 can press the stop plate 14 along the direction from the second end 12 to the first end 11. Since the guide frame 341 can slide relative to each other in the first direction, the stop rod 34111 disengages from the groove 3131. Under the action of the first elastic member 32, the limiting member 31 can move toward the first wall surface 13, so that the first mating part 3411 (stop rod 34111) and the second mating part 313 (groove 3131) can be spaced apart in the second direction to prepare for the next pull-out of the guide rail bracket 2. The slide rail device of the embodiment of this application, by adopting the above-mentioned structural arrangement, can automatically switch the state of the limiting member 31 when the guide rail bracket 2 is pulled to the limit position, which improves the linkage effect between various components of the slide rail device, has a reasonable structural design, and has a good use effect.

[0081] Optionally, such as Figure 10 As shown, the main housing 33 is provided with a second slide rail 332, and the limiting member 31 has a second guide rod 314, which slides through the second slide rail 332 in a second direction. Thus, the first slide rail 331 can provide guidance for the movement of the second guide rod 314, so that the movement of the limiting member 31 is more stable.

[0082] like Figure 10 and Figure 11 As shown, one end of the first elastic member 32 abuts against the limiting member 31, and the other end of the first elastic member 32 abuts against the main shell 33, thereby improving the stability of the connection of the first elastic member 32. For example, the first elastic member 32 is a cylindrical spring.

[0083] Optionally, such as Figure 7 and Figure 8 As shown, one of the main housing 33 and the guide rail bracket 2 is provided with a first engaging portion 333, and the other is provided with a first engaging groove 21. The first engaging portion 333 engages with the first engaging groove 21. This improves the ease of connection between the main housing 33 and the guide rail bracket 2. For example, the first engaging portion 333 consists of two hooks, which are arranged on both sides of the main housing 33 along a third direction (vertical direction), and engage with the first engaging groove 21.

[0084] like Figure 7 and Figure 8 As shown, the limiting component 3 also includes a first fastener 35, which passes through the main housing 33 and the guide rail bracket 2. This improves the reliability of the connection between the main housing 33 and the guide rail bracket 2. For example, the first fastener 35 is a bolt.

[0085] Optionally, such as Figure 4 and Figure 7 As shown, the slide rail device also includes a roller 4, which is rotatably mounted on the guide rail bracket 2, and the outer wall surface of the roller 4 abuts against the guide rail seat 1. This can reduce the resistance when the guide rail bracket 2 and the guide rail seat 1 slide against each other, and reduce the noise generated by sliding friction when the slide rail device is working.

[0086] like Figure 1 and Figure 2 As shown, another embodiment of the box assembly of this application includes: a box liner, a box body 5 and a slide rail device. The slide rail device is the slide rail device of this application. The box body 5 is removably installed in the box liner. The guide rail seat 1 is connected to the box liner, and the guide rail bracket 2 is connected to the box body 5. Both the guide rail seat 1 and the guide rail bracket 2 extend upward at an angle from the front side to the rear side of the box body 5.

[0087] According to the embodiment of the present application, the housing assembly is switchable between a released state and a locked state. In the locked state, the limiting member 31 is spaced apart from the first wall surface 13, thereby allowing the guide rail bracket 2 and the guide rail seat 1 to slide freely, thus avoiding the problem of jamming when the guide rail bracket 2 and the guide rail seat 1 slide. Since the first elastic member 32 presses the limiting member 31 in the direction toward the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thus, under the action of the elastic force of the first elastic member 32, the relative movement of the guide rail bracket 2 and the guide rail seat 1 can be constrained, thus avoiding the problem of the guide rail bracket 2 moving relative to the guide rail seat 1 under the action of gravity. This allows the housing 5 to be stopped in the required position, improving the user experience.

[0088] Optionally, such as Figure 1 and Figure 2As shown, the extension directions of the guide rail base 1 and the guide rail bracket 2 are inclined at an angle between 30° and 40° to the horizontal plane, which facilitates daily use by the user and does not interfere with the components around the housing 5. For example, the extension directions of the guide rail base 1 and the guide rail bracket 2 are inclined at an angle of 35° to the horizontal plane.

[0089] like Figure 5 and Figure 6 As shown, the bottom surface of the housing 5 is provided with a mounting block 51, and the guide rail bracket 2 is provided with a mounting groove 22. The mounting block 51 is fed into the mounting groove 22 in a top-to-bottom direction so that the housing 5 and the guide rail bracket 2 can be assembled.

[0090] like Figure 1 and Figure 2 As shown, another embodiment of the refrigerator of this application includes the cabinet assembly of the embodiment of this application.

[0091] According to the refrigerator of the embodiment of this application, since the limiting member 31 can switch between a released state and a locked state, in the locked state, the limiting member 31 is spaced apart from the first wall surface 13, thereby allowing the guide rail bracket 2 and the guide rail seat 1 to slide freely, so as to avoid the problem of jamming when the guide rail bracket 2 and the guide rail seat 1 slide. Since the first elastic member 32 presses the limiting member 31 in the direction toward the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thus, under the action of the elastic force of the first elastic member 32, the relative movement of the guide rail bracket 2 and the guide rail seat 1 can be constrained, so as to avoid the problem of the guide rail bracket 2 moving relative to the guide rail seat 1 under the action of gravity. Thus, the refrigerator body 5 can be stopped in the required position, improving the user experience.

[0092] For example, such as Figure 1 and Figure 2 As shown, the cabinet assembly is located near the lower side of the refrigerator and has a freezing function. Since both the guide rail base 1 and the guide rail bracket 2 extend upwards along the direction from the front side to the rear side of the cabinet 5, the cabinet 5 rises upwards when the user pulls it out. This reduces the user's bending over, making it easier for the user to put items into and take them out of the cabinet 5, thus improving the user experience.

[0093] like Figure 2 As shown, the guide rail bracket 2 is used to be installed on the box 5. When the user pulls out the box 5, the guide rail bracket 2 can slide relative to the guide rail seat 1 in the first direction.

[0094] like Figure 2 and Figure 3As shown, the slide rail device is arranged at an upward angle from front to back. When the box 5 is pulled upward at an angle from front to back, due to the weight of the box 5, the box 5 will exert a downward force on the guide rail bracket 2 under the action of gravity. Since the limiting member 31 can move relative to the guide rail bracket 2 in the second direction when it is released, the guide rail bracket 2 will not slide downward due to the gravity of the box 5 under the cooperation of the limiting member 31 and the first wall surface 13. Thus, the box 5 can be stopped in the position required by the user, thereby improving the user experience.
