[0002] Currently, the storage boxes of the central control of the interior trim of the automobile have the problem of unclear storage space layout. Specifically, although some storage boxes provide a large storage space, due to the lack of clear layered layout, when consumers place various use items in them, these items often appear disorganized, leading to the inability to quickly take the required items. This not only affects the user's experience, but also reduces the practicality of the storage box. On the other hand, some central control storage boxes of the automobile have the problem of insufficient storage space. Due to limited space, these storage boxes often cannot hold too many use items, or only a small part of the items occupies all the storage space. This also brings inconvenience to the user and limits their ability to store and carry items in the car. In addition, a common central control storage box structure on the market is a removable middle storage compartment form. Although this structure solves the problem of layered storage space to some extent, when accessing the lower items, the user needs to remove the middle storage compartment, which undoubtedly increases the operation complexity of accessing the items and affects the accessibility. At the same time, since the middle storage compartment is detachable, the user is likely to lose it during use, further reducing the practicality and user experience of the storage box.

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0026] Referring to Figures 1-6 As shown in the figure: a layered storage box structure suitable for automobile central control armrest, including storage box body 1, slidingly connected with armrest inner plate 2 in storage box body 1, the bottom of armrest inner plate 2 is provided with guide block 21, the inner wall of storage box body 1 is provided with guide groove 11 matched with guide block 21, guide block 21 is inserted in guide groove 11;Two moving blocks 22 are equidistantly arranged on guide block 21 along the long side direction of guide block 21;The moving block 22 close to armrest inner plate 2 is slidingly connected with upper layer storage grid 23, and the moving block 22 close to the bottom position of guide block 21 is slidingly connected with lower layer storage grid 24;Limiting groove 25 is formed on guide block 21, and threaded hole is formed on the top position of the side wall of guide groove 11, and bolt is screwed into threaded hole and inserted into limiting groove 25.

[0027] In the prior art, the lifting of the storage grid is realized by four connecting rods, but the connecting rod movement may have problems such as shaking, jamming or inaccurate movement trajectory. To solve this problem, in the present device, when the user manually pulls the armrest inner plate 2 outward, the guide blocks 21 on both sides of the bottom of the armrest inner plate 2 slide smoothly along the guide grooves 11 on the inner wall of the storage box body 1. Since the guide blocks 21 are fixedly connected with the armrest inner plate 2, their movement trajectory is completely controlled by the linear path of the guide grooves 11, ensuring the stability of the sliding process. In the long side direction of the guide block 21, the two equidistantly fixedly connected moving blocks 22 move synchronously with the guide block 21 - the moving block 22 close to the armrest inner plate 2 directly pulls the upper layer storage grid 23 out horizontally, and the sliding path of the upper layer storage grid 23 is constrained by the fixed relationship between the moving block 22 and the guide block 21; At the same time, the other moving block 22 close to the bottom of the guide block 21 drives the lower layer storage grid 24 to slide out in the same movement direction, but because the two moving blocks 22 are equidistantly distributed along the long side of the guide block 21, the sliding distance of the lower layer storage grid 24 is slightly smaller than that of the upper layer, thereby forming a stepped storage space with upper and lower layers.

[0028] During the sliding process, the limiting groove 25 pre-set on the guide block 21 and the bolt screwed into the top of the side wall of the guide groove 11 form mechanical interference. When the armrest inner plate 2 is pulled to the maximum stroke, the end of the bolt limits the guide block 21 from continuing to slide by physical blocking, preventing the armrest inner plate 2 from derailing due to excessive pulling out. When the user retracts the storage grid, the armrest inner plate 2 needs to be pushed in the opposite direction, at which time the guide block 21 retracts along the original path of the guide groove 11, and the upper layer storage grid 23 and the lower layer storage grid 24 are simultaneously reset to the inside of the storage box body 1 under the traction of the moving blocks 22.

[0029] Referring to Figures 1-4As shown: the bolt includes a threaded end 3 and a smooth end 4, when the threaded end 3 is screwed into the threaded hole, the smooth end 4 is inserted into the limiting groove 25.

[0030] When the threaded end 3 of the bolt is screwed into the threaded hole at the top of the side wall of the guide groove 11, the whole bolt is fixed to the inner wall of the storage box body 1, and the smooth end 4 at the other end is vertically inserted into the limiting groove 25 of the guide block 21, forming a slidable limiting structure.

[0031] Referring to Figures 1-5 As shown: the moving block 22 is provided with a moving track 221, and the upper layer storage compartment 23 and the lower layer storage compartment 24 are provided with roller wheels abutting against the moving track 221 at both ends.

[0032] The roller wheels roll along the surface of the moving track 221, converting traditional sliding friction into rolling friction, greatly reducing the resistance when the storage compartment is expanded, making the push-pull action more convenient and smooth.

[0033] Referring to Figure 5 As shown: the roller wheels are equidistantly arranged along the long edge direction of the moving track 221.

[0034] The equidistantly distributed roller wheels improve the sliding stability of the storage compartment through multi-point rolling support.

[0035] Referring to Figure 5 and Figure 6 As shown: the moving block 22 is provided with an anti-disengagement groove 222, the upper layer storage compartment 23 and the lower layer storage compartment 24 are provided with through holes on the two side walls abutting against the moving block 22, and the anti-disengagement rod 223 is arranged in the through hole and inserted into the anti-disengagement groove 222.

[0036] In the layered storage box structure, the combination of the anti-disengagement groove 222 and the anti-disengagement rod 223 prevents the upper layer storage compartment 23 and the lower layer storage compartment 24 from accidentally disengaging from the moving block 22 through mechanical constraint. When the upper layer storage compartment 23 and the lower layer storage compartment 24 are pulled out by hand, the anti-disengagement rod 223 arranged in the through hole of the two side walls moves synchronously with the storage compartment, and the end of the anti-disengagement rod 223 is inserted into the anti-disengagement groove 222 on the moving block 22, forming a double effect of sliding pair and limiting pair: the sliding of the anti-disengagement rod 223 in the anti-disengagement groove 222 allows the storage compartment to move freely in the predetermined direction of the moving block 22, and the groove wall of the anti-disengagement groove 222 physically blocks the transverse displacement of the anti-disengagement rod 223.

[0037] Referring to Figure 6The anti-disengaging rod 223 comprises a moving part 5 and a plug-in part 6, and the upper storage compartment 23 and the lower storage compartment 24 are provided with limiting rings 7 at the positions of the through holes to prevent the anti-disengaging rod 223 from moving excessively; when it is needed to take the upper storage compartment 23 and the lower storage compartment 24 off the moving block 22, the moving part 5 drives the plug-in part 6 to disengage from the anti-disengaging groove 222, at which time the anti-disengaging groove 222 loses the limiting effect on the upper storage compartment 23 and the lower storage compartment 24.

[0038] When the storage compartment is normally used, the moving part 5 of the anti-disengaging rod 223 is embedded into the through holes in the two side walls of the upper storage compartment 23 and the lower storage compartment 24, the plug-in part 6 thereof is inserted into the anti-disengaging groove 222 of the moving block 22 through the through hole, the limiting ring 7 clamps the moving part 5 of the anti-disengaging rod 223 to limit the axial displacement range of the anti-disengaging rod 223, so that the plug-in part 6 always maintains the plug-in state with the anti-disengaging groove 222, thereby preventing the storage compartment from being accidentally separated from the moving block 22.

[0039] Referring to Figure 6 As shown, the moving part 5 is sleeved with a reset spring; when the reset spring is in the original state, the plug-in part 6 of the anti-disengaging rod 223 is inserted into the anti-disengaging groove 222.

[0040] When it is needed to disengage the plug-in part 6 of the anti-disengaging rod 223 from the anti-disengaging groove 222, the moving part 5 is manually pulled to overcome the reset spring to drive the plug-in part 6 to move away from the anti-disengaging groove 222, so that the upper storage compartment 23 and the lower storage compartment 24 can be taken off the moving block 22.

[0041] Referring to Figure 1 As shown, the top of the handrail inner plate 2 is provided with a notch for easy grabbing.

[0042] The notch is hidden below the top plane of the handrail inner plate 2, and the outline thereof smoothly transitions with the surface of the handrail, which not only maintains the overall aesthetic appearance of the interior decoration, but also prevents accidental hooking of clothes or accessories.

[0043] Working principle: when the user pulls the handrail inner plate 2 outward, the bottom-fixed guide block 21 slides linearly along the guide groove 11 in the inner wall of the storage box, and the linear track design of the guide groove 11 eliminates the shaking problem of the traditional four-link structure, ensuring that the movement path is accurately controllable. The two moving blocks 22 in the long direction of the guide block 21 move synchronously with the guide block 21, wherein the moving block 22 close to the handrail inner plate 2 pulls the upper storage compartment 23 out horizontally through the sliding connection, and the moving block 22 close to the bottom drives the lower storage compartment 24 to move in the same direction. Since the two moving blocks 22 are equally distributed on the guide block 21, the sliding-out distance of the lower storage compartment 24 is slightly smaller than that of the upper storage compartment, forming a staggered step-shaped storage space, which not only facilitates the classified storage of articles, but also avoids the inconvenience of taking articles caused by the complete overlap of the upper and lower layers.

[0044] In the sliding process, the limiting groove 25 on the side of the guide block 21 and the bolt screwed into the top of the guide groove 11 form a limiting mechanism. The threaded end 3 of the bolt is fixed to the inner wall of the storage box, and the smooth end 4 is vertically inserted into the limiting groove 25. When the guide block 21 slides to the maximum stroke, the end of the bolt contacts the end of the limiting groove 25, preventing the inner plate 2 of the handrail from being pulled out too much by physical blocking, and avoiding the structure from derailing.

[0045] To reduce the frictional resistance when the storage compartment is expanded, the surface of the moving block 22 is provided with a moving track 221, and a plurality of equidistantly distributed roller wheels are installed at both ends of the upper storage compartment 23 and the lower storage compartment 24. The rolling contact between the roller wheels and the track converts the traditional sliding friction into rolling friction, making the push-pull action more convenient. The equidistantly arranged roller wheels also enhance the stability of the movement of the storage compartment through multi-point support, preventing tilting or jamming caused by uneven stress.

[0046] The composite structure of the anti-disengagement rod 223 and the anti-disengagement groove 222 further enhances the connection reliability of the storage compartment and the moving block 22. The anti-disengagement rod 223 is inserted through the through hole in the side wall of the upper storage compartment 23 and the lower storage compartment 24, and the insertion part 6 of the anti-disengagement rod 223 is embedded in the anti-disengagement groove 222 of the moving block 22, forming a sliding limiting pair. The groove wall of the anti-disengagement groove 222 limits the lateral displacement of the anti-disengagement rod 223, ensuring that the storage compartment can only move in the direction of the moving block 22 and cannot be disengaged. When it is necessary to disassemble the upper storage compartment 23 and the lower storage compartment 24, the moving part 5 of the anti-disengagement rod 223 can be pulled to overcome the pressure of the return spring, so that the insertion part 6 exits the anti-disengagement groove 222, realizing quick disassembly. The design of the limiting ring 7 prevents the anti-disengagement rod 223 from moving excessively, ensuring that the insertion part 6 is always effectively locked in the daily use state.

[0047] The hidden slot at the top of the inner plate 2 of the handrail not only ensures the beauty of the interior decoration, but also provides an ergonomic gripping position. The smooth transition of the slot edge and the handrail surface not only avoids damaging the overall design lines, but also effectively prevents accidental hooking of clothes or accessories. Users can easily pull the entire structure by applying force through the slot, and the precise guidance of the guide groove 11 realizes efficient use of the storage space and convenient operation.

[0048] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
