[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0147708, filed on October 31, 2023, which is incorporated herein by reference. Technical Field

[0003] The invention relates to a joint structure of a vehicle body. Background Art

[0004] The automotive industry has recently introduced a new vision of future mobility to enable dynamic, people-centric future cities. One of these future mobility solutions is the Purpose-Built Vehicle (PBV), a purpose-based mobility vehicle.

[0005] An example of a PBV may be an environmentally friendly mobile vehicle based on an electric vehicle (EV). The PBV may provide various customized services to users through autonomous driving, whether unmanned or manned, during transportation from a departure point to a destination.

[0006] The body of a PBV may include an underbody (also referred to in the industry as a chassis frame, rolling chassis, or skateboard), and an upper body assembled to the underbody.

[0007] Here, the upper body may have various forms based on the type of customized service of the PBV. For example, the PBV may be used as a call-type vehicle, in which a cabin is provided at the front and rear of the upper body. Also, the PBV may be used as a cab-type vehicle, in which a cab is provided only at the front of the upper body. Also, the PBV may be used as a delivery-type vehicle having a cabin (or drive module) at the front of the upper body and a luggage room (or space module) at the rear.

[0008] According to the conventional technology, as described above, the cost of changing the upper vehicle body structure may increase based on various customized services of PBV. Therefore, it is necessary to develop a vehicle body joint structure that can be changed into various types of vehicle bodies based on the customized service type of PBV. Summary of the invention

[0009] The present invention relates to a vehicle body joint structure, and a specific embodiment relates to a vehicle body joint structure, which may include a drive module and a space module in a private vehicle (PBV).

[0010] An embodiment of the present invention provides a vehicle body joint structure, wherein a drive module and a space module of the vehicle body can be detachable, the space module can be used as a detachable structure for various purposes and recycled, and the drive module can be detached during vehicle driving.

[0011] According to one embodiment, a vehicle body joining structure is provided, which includes: a drive module that can be removed from the front of the lower body of the vehicle; and a space module that has various shapes and is detachably mounted on the lower body, wherein the space module is joined to the lower body, is capable of moving independently, is joined to the drive module to communicate / cooperate with the drive module to move in groups, and is capable of being changed and replaced based on the shape and purpose of the space module.

[0012] The lower body is equipped with at least one replaceable battery for storing energy consumed by the space module.

[0013] The space module is equipped with a detachable controller, which controls the devices installed on the lower body, the drive module or the space module and performs calculations on the devices.

[0014] The space module is equipped with a detachable integrated thermal management device, which is arranged outside the space module and can perform cooling, heating and air conditioning in the space module, or cool the devices in the space module.

[0015] The space module is equipped with cameras for closed-circuit television (CCTV) and autonomous driving; space lighting devices for external lights and flashlights; and a solar roof for converting light energy into electricity.

[0016] The structure also includes a detachable dolly integrated module, which is disposed at the front of the lower vehicle body and driven by an in-wheel motor to move the space module when the space module is mounted on the lower vehicle body.

[0017] The trolley integrated module may include trolley autonomous driving electronic devices that enable low-speed autonomous driving and propulsion.

[0018] The structure also includes a rear wheel suspension device, which is provided at the rear of the lower vehicle body or the rear of the drive module and enables the space module to move.

[0019] The driving module includes a driving autonomous driving device and a driving lighting device which enable the driving module to travel and drive autonomously.

[0020] The space module is equipped with external air bags to absorb shock when the drive module and the space module collide with each other.

[0021] In the space module, additional space modules are connected to the sides of the space module by lateral connecting structures.

[0022] The rear wheel suspension device and the trolley integrated module are sequentially coupled to the rear of the driving module.

[0023] The driving module sensor is arranged at the rear of the driving module, and the space module sensor is arranged at the front of the space module. The distance and angle signals between the driving module and the space module are measured by mutual sensing of the driving module sensor and the space module sensor to be transmitted to the sensor control unit.

[0024] The sensor control unit controls the motor and wheels provided on the drive module according to the measured distance and angle signals.

[0025] The additional space module is also arranged at the rear end of the space module, wherein the additional space module is installed with an additional trolley integrated module and a rear wheel suspension device, and a rear connecting structure is installed between the space module and the additional space module and at the upper end of the detachable trolley integrated module to move the space module.

[0026] The space modules are used as expansion spaces by connecting them in a row or at right angles to each other using a connecting structure.

[0027] According to one embodiment of the present invention, the completed structure can be standardized and used in various spaces, can be used for various purposes through subscription services, and can also be used for access services such as banking, libraries, healthcare, shopping, etc.

[0028] Furthermore, by applying a combination of reusable drive modules and trolley integrated modules, resources can be used efficiently.

[0029] Furthermore, unlike a camper van that is used only during camping and is stored separately, by applying a space module that can be used even when the vehicle is stopped, the parking space can be used as a living space.

[0030] Tires, suspension and drive units can be installed only when necessary, increasing initial cost and flat spot issues on tires.

[0031] The space modules can be assembled with each other and easily moved by a driving device arranged underneath them to achieve automatic assembly, thereby improving the shortcomings of traditional mobile houses, such as narrow space and difficulty in moving after installation.

[0032] In addition, when applied to transportation vehicles such as articulated buses or bimodal trams, embodiments of the present invention can address the inefficiency problems that occur when the number of transport vehicles is based on time zones but not simultaneously in a variable manner by adding connection modules, and can improve turning radius, driving ability, climbing performance and other issues through the steering and drive functions of the trolley integrated module.
