Detachable suitcase

Abstract

A detachable luggage case comprises two opposing shells and a clamping assembly mounted to the shells. The clamping assembly can be freely assembled and disassembled from the shells. When the clamping assembly is assembled with both shells, the two shells are connected by the clamping assembly to form a single unit. During assembly, an elastic member on the clamping assembly presses against the inner frame, sandwiching the edges of the shells between the inner and outer frames. During disassembly, the elastic member is removed and the inner frame is then removed from the outer frame. This allows for easy assembly and disassembly, allowing the suitcase to be assembled or disassembled according to actual circumstances, effectively reducing its volume during transportation and storage.

[0029] See also Figures 1 to 7 , which is a detachable luggage case according to one embodiment of the present invention, comprising two opposing shells 10 and a clamping assembly 20 mounted in conjunction with the two shells 10. The clamping assembly 20 is freely attachable to the shells 10. When the clamping assembly 20 is attached to both shells 10, the two shells 10 are connected as a whole by the clamping assembly 20. Conversely, when the clamping assembly 20 is removed from the two shells 10, the two shells 10 and the clamping assembly 20 can be stored separately to reduce the size.

[0030] The clamping assembly 20 includes two assembly groups 30, a connector 40 connecting the two assembly groups 30, and locking members 50 respectively mounted on the two assembly groups 30. In this embodiment, the connector 40 is a hinge comprising two hinge pieces that can rotate relative to each other, and the two hinge pieces are respectively connected to the two assembly groups 30. The two assembly groups assembled on the hinge can rotate relative to each other, thereby placing the first shell 10 and the second shell 10 in an open or closed state. When the first shell 10 and the second shell 10 are in the closed state, the locking members 50 lock the two assembly groups.

[0031] Each assembly group 30 includes an outer frame 60, an inner frame 70 that cooperates with the outer frame 60, and an elastic member 80 mounted on the outer frame 60 to support the inner frame 70. Both the outer frame 60 and the inner frame 70 are aluminum frames. Using aluminum ensures assembly strength while making the product lighter. The connector 40 connects the outer frames 60 of the two assembly groups 30. The inner side of the outer frame 60 is provided with regularly spaced ribs 62. The inner side of the outer frame 60 is also provided with a plurality of cylindrical stop protrusions 61. The circumferential surface of each stop protrusion 61 near the end is provided with a stop recess 611.

[0032] The side of the inner frame 70 facing outward is also provided with a rib 72. By providing the ribs (62, 72) on the opposite sides of the inner frame 70 and the outer frame 60, the inner frame 70 and the outer frame 60 can better clamp the shell 10. The outer dimensions of the inner frame 70 are smaller than those of the outer frame 60. The main body of the outer frame 60 is arranged on the outer side of the inner frame 70. The inner frame 70 is provided with a plurality of mounting holes 71 arranged along the outer shape of the inner frame 70. The mounting holes 71 correspond to the limiting protrusions 61 one by one, and each limiting protrusion 61 passes through the mounting hole 71 from the outside and extends to the inner side of the inner frame 70.

[0033] The elastic member 80 includes two pressing plates 81, a torsion spring (not shown) and a connecting bar 82. The torsion spring is installed between the two pressing plates 81. The connecting bar 82 passes through the two pressing plates 81 at the same time. The two pressing plates 81 can rotate around the axis of the connecting bar 82. The two ends of the torsion spring press against the two pressing plates 81 outward, causing the two pressing plates 81 to open outward.

[0034] Specifically, the pressing piece 81 is provided with a rotating portion 811 protruding from the end position, the rotating portion 811 is provided with a perforation, and the pressing piece 81 is provided with an avoidance groove 812 on one side of the rotating portion 811, and the bottom of the avoidance groove 812 is arranged in an arc shape. During assembly, the two pressing pieces 81 are arranged opposite to each other, and the rotating portion 811 on one pressing piece 81 is inserted into the avoidance groove 812 of the other card. The perforations on the two pressing pieces 81 are aligned with each other in the axial direction, and the torsion spring is sleeved on the outside of the connecting strip 82. The connecting strip 82 passes through the perforations of the two pressing pieces 81 at the same time, and the two ends of the torsion spring respectively press against the two pressing pieces 81 outward. When the pressing piece 81 is squeezed away from one end of the connecting strip 82, the two ends of the torsion spring elastically contract.

[0035] The pressing piece 81 is further provided with a first introduction port 813 at one end away from the rotating part 811, and one of the pressing pieces 81 is further provided with a second introduction port 814 connected to the first introduction port 813. The diameter of the first introduction port 813 is larger than the diameter of the second introduction port 814, and the diameter of the second introduction port 814 is slightly larger than the outer diameter of the limiting protrusion 61 at the limiting recess 611, so that the pressing piece 81 can be clamped on the limiting recess 611 through the second introduction port 814.

[0036] When the detachable suitcase is assembled, the two assembly groups 30 are respectively installed with the two shells 10. The shells 10 are provided with a plurality of fixing holes 11 at the edge. The fixing holes 11 correspond one-to-one to the limiting protrusions 61 on the assembly group 30. The edge of the shell 10 is clamped between the outer frame 60 and the inner frame 70. The limiting protrusions 61 pass through the fixing holes 11 on the shell 10 and the mounting holes 71 of the inner frame 70 in sequence. One end of the limiting protrusion 61 near the limiting recess 611 extends from the mounting hole 71, and then each elastic member 80 is correspondingly installed on a limiting protrusion 61. During installation, the tail end of the pressing piece 81 (that is, the end away from the rotating part 811) is pressed, the torsion spring is elastically deformed, and then the first introduction port 813 of the elastic member 80 is clamped on the limiting protrusion 61. The elastic member 80 is further moved horizontally so that the second introduction port 814 is clamped on the limiting recess 611. When the elastic member 80 is released, the two pressing pieces 81 press the inner side surface of the limiting recess 611 and the inner frame 70 upward and downward respectively under the action of the torsion spring.

[0037] Preferably, in order to better install the inner frame 70 on the outer frame 60, the inner frame 70 is arranged in sections. By utilizing the aluminum material properties of the inner frame 70, appropriate bending and deformation can be performed. The segmented inner frame 70 can be installed on the outer frame 60 more quickly.

[0038] The beneficial effect of the detachable suitcase of the present invention is that: by providing the clamping assembly 20, the clamping assembly 20 can be freely disassembled and assembled on the shell 10. During assembly, the elastic member 80 on the clamping assembly 20 presses the inner frame 70, so that the edge portion of the shell 10 is clamped between the inner frame 70 and the outer frame 60. During disassembly, the elastic member 80 is removed, and then the inner frame 70 is taken out from the outer frame 60. The overall disassembly and assembly is convenient, and the suitcase can be assembled or disassembled according to actual scenarios, effectively reducing the volume during transportation and storage.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
