[0002] This application claims priority and benefit to Korean Patent Application No. 10-2024-0164115, filed with the Korean Intellectual Property Office on November 18, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to a cargo compartment structure for a mobile device, and more specifically, this disclosure relates to a cargo compartment structure for a mobile device capable of ensuring the strength of the cargo compartment door frame. Background Technology

[0004] Recently, the automotive industry has introduced new concepts for the vision of future mobility, aiming to realize dynamic, human-centered future cities. One of these future mobility solutions is purpose-built mobile devices – dedicated personal vehicles (PBVs).

[0005] Examples of PBVs are environmentally friendly mobility vehicles based on electric vehicles (EVs). These PBVs can offer users a variety of customized services. PBVs can be configured in various forms depending on the type of customized service.

[0006] For example, a PBV can be used as a "hail-and-go" vehicle for transporting passengers by configuring passenger compartments in the front and rear of the vehicle body. In addition, a PBV can also be used as a cargo box vehicle (often referred to by those skilled in the art as a delivery type), which has a passenger compartment in the front of the vehicle body and a cargo box body assembly in the rear of the vehicle body.

[0007] The cargo box body assembly has a lower body and an upper body assembled to the lower body. For ease of assembly, the upper body mainly uses sandwich panels.

[0008] The cargo door is installed at the rear of the cargo body assembly to open and close the cargo space. The cargo door is mounted on a cargo door frame, which is connected to the opening edge at the rear of the upper body.

[0009] The cargo box door frame is located at the rear opening edge of the upper body and is riveted to the upper body's interlayer plate. The cargo box door frame is riveted to the mounting surface along the vehicle width direction at the rear opening edge of the upper body.

[0010] Because the cargo door frame located at the rear opening edge of the upper body is simply connected to the sandwich panel of the upper body, sagging and torsional deformation of the cargo door may occur during vehicle operation.

[0011] The contents included in this background section are intended to facilitate an understanding of the background of the invention and may include matters that are not conventional techniques known to those skilled in the art. Summary of the Invention
