Description

Technical Field

[0001] This application relates to the field of commercial vehicle technology, and in particular to a commercial vehicle side panel and body-in-white. Background Technology

[0002] Commercial vehicles are automobiles used to transport people and goods. They are an important part of the transportation industry and play a crucial role in economic development.

[0003] The A-pillar refers to the connecting pillar between the roof and the front compartment on the left and right front sides, located between the engine compartment and the driver's compartment, above the left and right rearview mirrors. In commercial vehicles with related technologies, the driver's cab door is hinged to the A-pillar on the left side panel, allowing the driver to enter or exit the cab when the door is opened.

[0004] However, after opening the cab door of a commercial vehicle, the driver is obstructed by the door, requiring the driver to turn or turn to enter the cab. This results in an unfavorable body posture when entering the cab and poor comfort when getting in. Summary of the Invention

[0005] This application provides a commercial vehicle side panel and body-in-white to solve the problem of poor driver comfort when getting into the vehicle.

[0006] This application provides a side panel for a commercial vehicle, including an outer side panel structure and an inner side panel structure. The outer side panel structure includes an outer side panel body and an A-pillar assembly connected to the outer side panel body. The inner side panel structure includes an inner side panel body and a B-pillar assembly connected to the inner side panel body. The outer side panel body is connected to the inner side panel body. The A-pillar assembly and the B-pillar assembly are arranged sequentially from the front to the rear of the vehicle. The A-pillar assembly is provided with a locking hook for engaging with the driver's cab door. The B-pillar assembly is provided with a hinge for hinged with the driver's cab door.

[0007] By adopting the above technical solution, the cab door can be hinged to the B-pillar assembly through the hinge configuration. When the driver opens the cab door, the door opens along the B-pillar assembly as the hinge axis towards the side away from the front of the vehicle, so that the cab door does not obstruct the driver and allows the driver to directly enter the driver's seat without having to turn or turn sideways to enter the driver's seat, thus improving the driver's comfort when getting into the vehicle. The locking hook is set on the A-pillar assembly, which facilitates the opening or locking of the cab door between the driver's door and the locking hook. The use of the outer and inner side panel structures increases the strength of the side panels, which indirectly increases the hinge strength of the cab door hinged to the B-pillar assembly.

[0015] By adopting the above technical solution, in the event of an impact, the side panel assembly and the A-pillar assembly can achieve multiple buffering effects due to the setting of the first cavity, which increases the connection strength and impact resistance of the side panel body and the A-pillar assembly; the setting of the second cavity also increases the connection strength and impact resistance of the side panel body and the B-pillar assembly.

[0016] In some embodiments, the B-pillar assembly includes a B-pillar body and a hinge reinforcement fixed to the B-pillar body; the hinge is connected to the hinge reinforcement.

[0017] By adopting the above technical solution, the setting of the hinge reinforcement improves the strength of the B-pillar assembly, thereby indirectly improving the fixing strength of the hinge to the B-pillar assembly, and indirectly improving the hinge strength of the cab door to the B-pillar assembly.

[0018] In some embodiments, the B-pillar assembly further includes a hinge mounting reinforcement; the hinge mounting reinforcement is fixed to the hinge reinforcement; the hinge is fixed to the hinge mounting reinforcement.

[0019] By adopting the above technical solution, the locking hook is fixed to the B-pillar by setting the hinge installation reinforcement, thereby further improving the installation strength of the hinge on the B-pillar, and further indirectly improving the hinge strength of the cab door hinged to the B-pillar assembly.

[0020] In some embodiments, the hinge reinforcement is provided with a second flap, and the hinge mounting reinforcement is fixedly connected to the second flap.

[0021] By adopting the above technical solution and using the second flap, it is easy to install and fix the hinge mounting reinforcement without adding any other parts. The structure is simple and the fixing effect of the hinge mounting reinforcement is improved.

[0022] In some embodiments, the inner side panel body includes an inner pillar, an inner side panel, and an inner sill panel; the inner pillar, the B-pillar assembly, and the inner side panel are arranged sequentially along the direction from the front of the vehicle to the rear of the vehicle; the inner pillar is positioned directly opposite the A-pillar assembly and is connected to the A-pillar assembly; the upper end of the inner pillar is connected to the upper end of the B-pillar assembly, and the lower end of the inner pillar is connected to the lower end of the B-pillar assembly through the inner sill panel; the inner side panel is connected to both the B-pillar assembly and the outer side panel structure.

[0023] By adopting the above technical solution, by setting the inner pillar on the A-pillar assembly, setting the upper end of the inner pillar on the upper end of the B-pillar assembly, and setting the lower end of the inner pillar on the lower end of the B-pillar assembly through the sill inner panel, the strength of the entire side panel body is further improved, and the opening and closing effect of the driver's cab door is indirectly improved.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0059] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0060] First, the relevant concepts or terms involved in this application will be explained:

[0061] A-pillar: It is the connecting pillar between the roof and the front compartment on the left and right front sides, located between the engine compartment and the driver's compartment, above the left and right rearview mirrors.

[0062] The B-pillar refers to the area between the front and rear doors of a car, which bears the pressure from the roof and the front and rear doors.

[0063] Body-in-white: refers to the body that has been welded but not yet painted. The painted body-in-white, along with the interior and exterior trim, electronic and electrical systems, chassis system, and powertrain system, constitutes the complete vehicle.

[0064] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials.

[0065] Commercial vehicles are automobiles designed and technically characterized for transporting people and goods.
