Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration, in particular to a pull-out storage device and an automobile. Background Art

[0002] Pull-out storage devices are often used as automotive interior parts to store mobile phones, wallets, tickets and other items. Pull-out storage devices are usually equipped with two parallel guide rails to enable the storage box to slide in and slide along the extension direction of the guide rails. At present, the use experience of pull-out storage devices is poor. Once the parallelism of the double guide rails is not enough, the smoothness of the storage box sliding along the guide rails decreases and the feeling of sticking is obvious. In addition, the double guide rail solution makes the material and assembly costs of the pull-out storage device high. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0024] The utility model provides a pull-out storage device and a car including the pull-out storage device. The pull-out storage device is often used as an automobile interior decoration part to store objects such as mobile phones, wallets, water cups, tickets, etc. Of course, the pull-out storage device can also be used in other places or equipment, such as office supplies, furniture, kitchen and bathroom appliances, etc. The utility model does not limit the use occasions of the pull-out storage device and the type of equipment to which it belongs.

[0025] See also Figure 1 The pull-out storage device of the utility model includes a storage box 10, a storage piece 20, a guide rail 31 and a sliding connection portion 32. The storage box 10 has a storage cavity 11 for placing objects, and also includes a sliding rail connecting portion 15. The storage piece 20 is provided with a storage cavity 21, and the storage cavity 21 is used for the storage box 10 to move in and out. A sliding adaptation is formed between the guide rail 31 and the sliding connection portion 32. One of the guide rail 31 and the sliding connection portion 32 is arranged on the storage piece 20, and the other is arranged on the sliding rail connecting portion 15.

[0026] In some embodiments, the storage cavity 11 penetrates through the top of the storage box 10 to form a storage opening. The receiving member 20 is provided with a hollowed-out groove, and the inner wall surface of the hollowed-out groove encloses to form a receiving cavity 21. The extending direction of the hollowed-out groove is the same as the extending direction of the guide rail 31. The hollowed-out groove penetrates through one side of the receiving member 20 to form a receiving opening for the storage box 10 to move into and out of the receiving cavity 21. When the storage box 10 is pulled out of the receiving cavity 21, the storage opening is exposed so that objects can be put into or taken out of the storage cavity 11. When the storage box 10 is pushed into the receiving cavity 21, the storage opening is closed by the receiving member 20. One of the guide rail 31 and the sliding connection portion 32 is provided on the inner wall surface of the hollowed-out groove.

[0027] In the existing pull-out storage devices, generally two or more guide rails are arranged on the receiving member parallel to each other. However, the guide rails themselves have extremely high requirements for manufacturing precision to ensure the straightness of the guide rails so as to ensure the smooth sliding of the storage box along the extending direction of the guide rails. And there are also relatively high requirements for the parallelism between multiple guide rails. Otherwise, it will cause obvious jamming when the storage box slides, and in addition, there may be sliding friction noise and collision interference abnormal noise between the storage box and the receiving member.

[0028] In view of this, the pull-out storage device of the present utility model further includes a support structure 40 provided on the receiving member 20. The storage box 10 further includes a supported portion. The support structure 40 abuts against the supported portion and forms a movable contact between the supported portion and the support structure 40.

[0029] The pull-out storage device of the present utility model allows only one guide rail 31 to be configured, without having to follow the scheme of parallel arrangement of two guide rails 31 as adopted by existing similar products. The single guide rail 31 reduces the material cost and assembly cost of the pull-out storage device, saves the time, labor and tooling costs invested in ensuring the parallelism of multiple parallel guide rails 31, and also eliminates the defect of poor smoothness and obvious jamming when the storage box 10 slides due to the poor parallelism of multiple guide rails 31. The single guide rail 31 can meet the requirement of the storage box 10 moving into and out of the receiving cavity 21. The support structure 40 provides an auxiliary supporting force for the storage box 10 in a manner of movably abutting against the supported portion to ensure the attitude stability of the storage box 10 during sliding.

[0030] Further, in some embodiments, the storage box 10 further includes a deformable portion. The slide rail connecting portion 15 and the supported portion are connected by the deformable portion. The deformable portion has a certain degree of deformation ability. The deformation generated when the deformable portion is stressed can drive the supported portion to move relative to the slide rail connecting portion 15. The movement of the supported portion relative to the slide rail connecting portion 15, on the one hand, ensures that the support structure 40 continuously abuts against the supported portion, and on the other hand, allows the contact elements (such as contact lines and contact surfaces) between the supported portion and the support structure 40 to be appropriately offset until the jamming degree between the supported portion and the support structure 40 is relieved, so as to prevent excessive pressure and friction from being generated between the support structure 40 and the supported portion, ensuring that the storage box 10 can be smoothly moved into and out of the storage cavity 21. In this way, the force exerted by the user when pulling or pushing the storage box 10 can be reduced, and the bending deformation ability of the deformable portion allows the supported portion to move relative to the slide rail connecting portion 15, enabling the active abutment between the support structure 40 and the supported portion to adapt to the change in the load-bearing weight of the storage box 10 in real time.

[0031] Taking the existing double-rail parallel arrangement scheme as an example, the double-rail parallel arrangement requires rigid settings for the two sliding connection portions respectively adapted to the two rails, that is, the storage box must be a rigid member to ensure that the two sliding connection portions are relatively fixed to adapt to the two parallel rails. However, in actual applications, the relative positions of the two sliding connection portions of the storage box change due to assembly and use factors. The two sliding connection portions with changed relative positions are obviously in conflict with the double-rail parallel arrangement, which is the reason for the poor smoothness, obvious jamming feeling, and serious noise when pulling or pushing the storage box in the existing pull-out storage device.

[0032] The pull-out storage device of the present utility model can enable the active abutment between the support structure 40 and the supported portion to adapt to the change in the load-bearing weight of the storage box 10. The objects in the storage cavity 11 cause the deformable portion to deform and bend, and the supported portion is thus driven by the deformable portion to move relative to the slide rail connecting portion 15. The bending deformation amplitude of the deformable portion increases as the total weight of the objects in the storage cavity 11 increases and decreases as the total weight of the objects in the storage cavity 11 decreases. As the deformable portion generates bending deformations of different amplitudes, the movement amplitude of the supported portion relative to the slide rail connecting portion 15 changes. Therefore, the position where the support structure 40 abuts against the supported portion changes with the change in the total weight of the objects in the storage cavity 11, ensuring that the supported portion is actively abutted by the support structure 40 at any time, while not affecting the movement of the supported portion relative to the slide rail connecting portion 15, so that the storage box 10 is always subjected to the auxiliary supporting force of the support structure 40 to maintain a stable posture.

[0033] Since the support structure 40 applies auxiliary support force to the storage box 10 in a movable abutment manner, the pull-out storage device of the utility model can be equipped with only one guide rail, instead of adopting a parallel arrangement of two guide rails like existing similar products. Fewer guide rails reduce the material cost and assembly cost of the pull-out storage device, and avoid the poor parallelism of multiple guide rails causing the storage box to be stuck when sliding. When the support structure 40 supports the storage box 10, a single guide rail will not cause the storage box 10 to become unstable and shake.

[0034] In some embodiments, the support structure 40 includes a support rib 41 protruding from the inner wall of the storage cavity 21, and the supported portion includes a sliding contact portion 141. The support rib 41 and the sliding contact portion 141 are in sliding contact with each other, and the contact form between the two can be line contact or surface contact. Figure 1 The storage box 10 includes a storage bottom plate 12 for carrying objects, and also includes a storage baffle that is bent and connected to the outer peripheral edge of the storage bottom plate 12. The storage baffle extends along the outer peripheral edge of the storage bottom plate 12 to form a closed loop structure, and is surrounded by the storage baffle to form a storage cavity 11. The storage opening is the edge of the storage baffle that is relatively far away from the storage bottom plate 12. The support rib 41 includes a guide support seat 412 protruding from the inner wall surface of the storage cavity 21, and also includes an elastic layer 411 provided on the top of the guide support seat 412. The thickness of the elastic layer 411 decreases as the pressure on the elastic layer 411 increases, and increases as the pressure decreases. The slide rail connection portion 15 and the sliding contact portion 141 are located on the side of the storage bottom plate 12 away from the storage cavity 11, and the sliding contact portion 141 slides and abuts against the elastic layer 411 to form a line contact or a surface contact. The deformable portion includes a deformable bottom plate, which is formed by a storage bottom plate 12 located between the rail connection portion 15 and the sliding contact portion 141. If the rail connection portion 15 is used as a reference system, the sliding contact portion 141 swings around the rail connection portion 15 as the deformable bottom plate bends.

[0035] Optionally, the elastic layer 411 is an elastic buffer block made of TPU material, which has good wear resistance and buffer shock absorption performance. The advantages of setting the elastic layer 411 include: ① buffering the pressure between the buffer support rib 41 and the sliding contact part 141, reducing the respective pressure peaks of the sliding contact part 141 and the support rib 41, thereby delaying the wear rate; ② the thickness of the elastic layer 411 decreases as the total weight of the objects carried by the storage bottom plate 12 increases, and increases as the total weight of the objects carried by the storage bottom plate 12 decreases, ensuring that the support rib 41 and the sliding contact part 141 slide and abut for a long time, and reducing the variation range of the abutting pressure and friction force between the two; ③ as the total weight of the objects carried by the storage bottom plate 12 changes, the deformation amplitude of the deformable bottom plate changes, and the change in the thickness of the elastic layer 411 adapts to the change in the bending amplitude of the deformable bottom plate, allowing the sliding contact part 141 to move relative to the rail connection part 15. The elastic buffer block made of TPU material can also bring damping to the storage box 10, preventing the storage box 10 from accidentally sliding out of the storage cavity 21 during sudden acceleration, emergency braking or rapid turning of the vehicle. Of course, an elastic layer 411 supported by other soft and wear-resistant materials can also be used.

[0036] As Figure 1 shown, optionally, two sliding contact parts 141 are configured and two support ribs 41 are also configured as two. The two sliding contact parts 141 are respectively located on both sides of the rail connection part 15. The deformable part includes a first deformable bottom plate and a second deformable bottom plate. The first deformable bottom plate is the part of the storage bottom plate 12 between the rail connection part 15 and one of the sliding contact parts 141, and the second deformable bottom plate is the part of the storage bottom plate 12 between the rail connection part 15 and the other sliding contact part 141. Both the first deformable bottom plate and the second deformable bottom plate can be bent and deformed, and the two can respectively drive the two sliding contact parts 141 to swing around the rail connection part 15. The two support ribs 41 respectively abut against the two sliding contact parts 141 in a one-to-one correspondence to form a line contact or a surface contact. The extending direction of the support rib 41 can be the same as the extending direction of the guide rail 31, which is beneficial to improving the sliding smoothness of the storage box 10. Of course, the extending direction of the support rib 41 can also be different from the extending direction of the guide rail 31, which does not affect the sliding abutment between the sliding contact part 141 and the support rib 41.

[0037] In some other embodiments, only one support rib 41 and one sliding contact part 141 can also be configured respectively. Taking the Figure 1 pull-out storage device shown as an example, the sliding contact part 141 on the left side of the rail connection part 15 and the support rib 41 on the left side of the guide rail 31 are retained, the sliding contact part 141 on the right side of the rail connection part 15 and the support rib 41 on the right side of the guide rail 31 are cancelled, and the guide rail 31 and the rail connection part 15 are shifted to the right by a certain distance.

[0038] Refer to Figure 1, in some embodiments, the storage baffle includes two side baffles 13 that are spaced apart and oppositely arranged and are respectively bent and connected to both sides of the storage bottom plate 12. The extending direction of the side baffles 13 is the length direction of the guide rail 31. A storage cavity 11 is formed between the two side baffles 13. The side of each side baffle 13 facing away from the storage cavity 11 faces the inner wall surface of the storage cavity 21. The supported part includes a side convex edge 142, and the side convex edge 142 protrudes from the side of the side baffle 13 facing the inner wall surface of the storage cavity 21. The support structure 40 includes a guide groove 42 for the side convex edge 142 to extend into. The guide groove 42 is opened on the inner wall surface of the storage cavity 21 arranged opposite to the side baffle 13. The side convex edge 142 extending into the guide groove 42 is in sliding contact with the inner wall of the guide groove 42. The guide groove 42 can be arranged to extend along the length direction of the guide rail 31 to define the sliding direction of the storage box 10.

[0039] Specifically, the deformable part includes the above-mentioned side baffle 13, and the side baffle 13 also has the ability to bend and deform. On the one hand, the side baffle 13 can swing or bend around the edge of the storage bottom plate 12, thereby driving the side convex edge 142 to swing relative to the storage bottom plate 12 in the guide groove 42. On the other hand, the side baffle 13 and the deformable bottom plate can swing around the slide rail connecting part 15 synchronously as a whole. If the slide rail connecting part 15 is used as a fulcrum, then the deformable bottom plate will bend around the slide rail connecting part 15 under the pressure of the objects in the storage cavity 11. Therefore, the position where the support rib 41 abuts against the sliding contact part 141 is used as a resistance point, and the side baffle 13 will also bend around the edge of the storage bottom plate 12 under the pressure of the objects in the storage cavity 11. Therefore, the position where the inner wall of the guide groove 42 abuts against the side convex edge 142 is used as another resistance point. In this way, the posture of the storage box 10 is maintained stable, and the storage box 10 will not be unbalanced and shaken due to there being only one guide rail 31.

[0040] Optionally, as Figure 1 shown, the edge of the storage opening includes the edge of the side baffle 13 relatively far away from the storage bottom plate 12, and the side convex edge 142 is bent and connected to the edge of the side baffle 13 relatively far away from the storage bottom plate 12. In this way, the side convex edge 142 not only serves as the supported part that slides in contact with the inner wall surface of the guide groove 42, but also serves as the flanging of the storage opening of the storage box 10. The side convex edge 142 can improve the rigidity of the storage opening and simplify the structure of the storage box 10. Even if the Figure 1 support rib 41 of the pull-out storage device is cancelled, and only the inner wall surface of the guide groove 42 slides in contact with the side convex edge 142, the posture stability of the storage box 10 during the sliding process can also be maintained. In some other embodiments, the side convex edge 142 and the guide groove 42 of the pull-out storage device in Figure 1 can also be cancelled, and only the support rib 41 abuts against the sliding contact part 141 to maintain the posture stability of the storage box 10 during the sliding process; or the Figure 1The support rib 41 of the middle-pull-out storage device maintains the attitude stability of the storage box 10 during the sliding process only by the abutting side convex edge 142 against the inner wall surface of the guide groove 42.

[0041] Furthermore, in the state where the side convex edge 142 extends into the guide groove 42, a fitting gap is formed between the inner wall surface of the guide groove 42 and the side convex edge 142, and the fitting gap extends along the length direction of the guide rail 31. The setting of the fitting gap allows the side convex edge 142 to move slightly within the guide groove 42. The movement of the side convex edge 142 within the guide groove 42 can be the result of the bending of the side baffle 13, which drives the side convex edge 142 to swing around the edge of the storage bottom plate 12, or the result of the bending of the deformable bottom plate, which drives the side convex edge 142 to swing around the slide rail connecting part 15, or the result of the superposition of the swing of the side convex edge 142 around the edge of the storage bottom plate 12 and the swing of the side convex edge 142 around the slide rail connecting part 15. With such a setting, it can be ensured that the sliding abutting support of the inner wall surface of the guide groove 42 against the side convex edge 142 will not fail due to the change in the total weight of the objects in the storage cavity 11. Due to the change in the deformation amplitude of the side baffle 13 and the deformable bottom plate caused by the change in the total weight of the objects in the storage cavity 11, the position of the side convex edge 142 relative to the receiving member 20 changes, and the fitting gap between the inner wall surface of the guide groove 42 and the side convex edge 142 can well adapt to the position change of the side convex edge 142 to avoid jamming of the side convex edge 142 and jamming of the side convex edge 142 in the guide groove 42.

[0042] Optionally, the width range of the fitting gap is at least not less than 0.3 mm and at most not greater than 2 mm.

[0043] Optionally, the thickness of the elastic layer 411 is d2, and the gap between the top end of the guide support seat 412 and the sliding contact part 141 is d1, d1 ≤ 2d2, d1 = a × tan1°. Refer to Figure 1 , the storage bottom plate 12 includes a first side edge and a second side edge arranged opposite to each other, the slide rail connecting part 15 is centrally located between the first side edge and the second side edge, and the two side baffles 13 are respectively bent and connected to the first side edge and the second side edge. The storage bottom plate 12 is horizontally arranged. If a plane passing through the slide rail connecting part 15 and perpendicular to the storage bottom plate 12 is made, then the maximum horizontal distance from this plane to the side convex edge 142 is a.

[0044] Further, in some embodiments, at least one of the inner wall surface of the guiding groove 42 and the side convex edge 142 is convexly provided with a plurality of contact convex protrusions 421, and the plurality of contact convex protrusions 421 are arranged at intervals in sequence along the length direction of the guide rail 31. The arrangement of the contact convex protrusions 421 can reduce the contact area between the inner wall surface of the guiding groove 42 and the side convex edge 142, and a discontinuous intermittent contact line or contact surface is formed between the side convex edge 142 and the inner wall surface of the guiding groove 42, which helps to reduce the frictional resistance of the side convex edge 142 sliding in the guiding groove 42, so that the side convex edge 142 slides more smoothly in the guiding groove 42, and can reduce the frictional noise when the side convex edge 142 slides in the guiding groove 42 and delay the wear of the side convex edge 142.

[0045] Refer to Figure 2 , the inner wall surface of the guiding groove 42 is convexly provided with contact convex protrusions 421. In addition, the inner wall surface of the guiding groove 42 is further provided with a slope surface 422, and the slope surface 422 is inclined and transitions from the top of the contact convex protrusion 421 to the inner wall surface of the guiding groove 42. Therefore, the contact convex protrusions 421, the slope surface 422 and the inner wall surface of the guiding groove 42 form a wavy surface, the wave crest of the wavy surface corresponds to the top of the contact convex protrusion 421, the wave trough of the wavy surface corresponds to the inner wall surface of the guiding groove 42, and the wave crests and wave troughs are arranged alternately in sequence along the length direction of the guide rail 31. In this way, the arrangement of the slope surface 422 further reduces the frictional resistance when the side convex edge 142 slides in the guiding groove 42, and the slope surface 422 can guide the end of the side convex edge 142 to prevent the end of the side convex edge 142 from being stuck between two adjacent contact convex protrusions 421 during the process of pulling and pushing the storage box 10.

[0046] It can be understood that in other embodiments, the contact convex protrusions 421 are convexly provided on the side convex edge 142, and the side convex edge 142 can also be provided with a slope surface 422, and the slope surface 422 is inclined and transitions from the top of the contact convex protrusion 421 to the surface of the side convex edge 142, so that the contact convex protrusions 421, the slope surface 422 and the surface of the side convex edge 142 form a wavy surface.

[0047] Optionally, the deformable part is an elastic structure, that is, at least one of the deformable bottom plate and the side baffle is an elastic structure. When at least one of the deformable bottom plate and the side baffle is stressed, it undergoes elastic bending deformation, and when the object is taken out of the storage cavity 11, the elastic deformation of the deformable bottom plate and the side baffle disappears.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0049] Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present utility model, they fall within the scope of protection required by the present utility model.
