A type of carriage panel connection structure

Abstract

This utility model discloses a vehicle body panel connection structure, including an outer shell, which comprises two centrally symmetrically arranged shells. A buckle is provided on one side of each shell, and a connecting groove is provided on the buckle. The shell, buckle, and connecting groove are integrally formed. A second movable groove is provided on the arc-shaped end face of the connecting groove, and a first movable groove is provided on the end face of the shell. This solution, through the centrally symmetrical fitting structure of the bullet-shaped buckle and the semi-circular connecting groove, ensures that the force at the connection point is evenly distributed, effectively solving the stress concentration problem caused by uneven force distribution in existing bolt connections and simple buckles. Simultaneously, the hollow design of the two parts of the outer shell reduces weight while, in conjunction with the precise fit of rotating components and the connecting groove, forming multi-point collaborative fixing, significantly improving the connection reliability in heavy-duty transportation scenarios, avoiding loosening or component damage due to vibration during long-term use, and ensuring the overall structural strength of the vehicle body.

Description

Technical Field

[0001] This utility model relates to the field of vehicle body panel connection technology, and in particular to a vehicle body panel connection structure. Background Technology

[0002] In the field of equipment such as freight vehicles and special-purpose carriages, the connection structure of the carriage panels is a core component that ensures the overall strength and safety of the carriage. The mainstream connection methods in the existing technology include bolt fastening and welding. Bolt connection requires multiple sets of fasteners and tools for assembly, and each fastener must be tightened and loosened one by one during disassembly, which is inefficient. The connection parts are subjected to uneven stress, which can easily lead to damage due to stress concentration, and some lack some buffer components. The existing car body panel connection structure has obvious defects: First, it has no buffer protection when facing bumps and impacts, and it cannot achieve stable linkage by driving the components through the piston rod; Second, the existing adjustment structure is complicated to operate and has poor locking reliability, making it difficult to achieve rapid assembly and fixation. At the same time, it has not formed an overall design for the coordinated work of various components, and cannot take into account the requirements of connection strength, ease of operation and buffer protection. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle body panel connection structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vehicle body panel connection structure includes an outer shell, which includes two centrally symmetrically arranged shells. A buckle is provided on one side of each shell, and a connecting groove is provided on the buckle. The shell, buckle, and connecting groove are integrally formed. A second movable groove is provided on the arc end face of the connecting groove, and a first movable groove is provided on the end face of the shell. The connecting mechanism includes two rotating parts that form a cylindrical structure, and an operating shaft is fixed on one side of each of the two rotating parts. The gas spring is rotatably mounted on the housing, and its movable end is rotatably connected to the operating shaft.

[0005] Preferably, the connecting groove has a semi-circular arc structure.

[0006] Preferably, the first movable groove is located on top of the entire housing.

[0007] Preferably, the outer casing has an opening groove on one side, which is a first movable groove through which the operating shaft passes.

[0008] Preferably, the two connecting mechanisms are centrally symmetrical.

[0009] Preferably, the operating shaft moves within the second movable slot.

[0010] This utility model has the following beneficial effects: 1. This utility model adopts an integrated molding design for the shell, buckle, and connecting groove, eliminating gaps and weak points caused by splicing or welding, and greatly improving the overall structural strength of the shell. The connecting groove is a semi-circular arc structure, which, together with the cylindrical structure composed of two rotating parts, can evenly distribute external forces to all parts of the shell, avoiding deformation caused by local stress concentration. At the same time, the two connecting mechanisms are centrally symmetrically arranged to further optimize the force balance. Even in heavy-duty transportation or bumpy scenarios, it can effectively reduce the risk of loosening or damage of the connecting parts and extend the service life of the structure.

[0011] 2. The gas spring in this utility model rotates to connect the housing and the operating shaft. Its movable end can provide auxiliary thrust. During operation, it is only necessary to move the operating shaft along the first movable groove to easily drive the two rotating parts to open and close, and complete the connection and disassembly of the carriage panel without relying on external tools such as wrenches. Compared with the traditional bolt fastening or manual buckle structure, a single person can quickly complete the operation, which greatly shortens the assembly and maintenance time and reduces labor costs. It is especially suitable for batch carriage assembly or frequent disassembly and assembly scenarios. Attached Figure Description

[0019] In this invention, the first movable groove 104 is located above the entire outer shell 1.

[0020] In this embodiment, the first movable groove 104 is located above the entire outer shell 1, providing a reasonable movement path for the operating shaft 202 and facilitating operation and component coordination. The outer shell 1 is composed of a centrally symmetrical shell 101, with a buckle 102 and a connecting groove 103 integrally formed on one side for docking with the carriage panel. The second movable groove 105 of the connecting groove 103 assists in the movement of the component. The rotating component 201 of the connecting mechanism 2 is a set of cylinders, the operating shaft 202 transmits the action, and the gas spring 3 provides elastic support. Together with the first movable groove 104 above, the carriage panel is securely connected and easy to operate.

[0021] In this utility model, the outer shell 1 has an opening groove and a first movable groove 104 on one side, and the operating shaft 202 passes through the first movable groove 104.

[0022] In this embodiment, the outer shell 1 has an opening groove and a first movable groove 104 on one side for the operating shaft 202 to pass through, providing a moving path for it and ensuring smooth movement of the connecting mechanism 2. The outer shell 1 is composed of a centrally symmetrical shell 101, and a buckle 102 and a connecting groove 103 on one side are integrally formed for docking the carriage panel. The second movable groove 105 of the connecting groove 103 assists in the movement of the component. The rotating component 201 of the connecting mechanism 2 is a cylindrical body, and the gas spring 3 elastically supports the operating shaft 202. With the design of the first movable groove 104, the carriage panel is stably connected and flexibly adjusted.

[0023] In this utility model, the two connecting mechanisms 2 are centrally symmetrical.

[0024] In this embodiment, the two connecting mechanisms 2 are centrally symmetrical and can be precisely adapted to the equally centrally symmetrical outer shell 1 by the shell 101 to ensure balanced force.

At this time, the gas spring 3 generates elastic deformation as the operating shaft 202 moves. After the car body panel is aligned with the buckle 102 and the semi-circular arc connecting groove 103 of the outer shell 1, the operating shaft 202 is released. Under the elastic force of the gas spring 3, the rotating parts 202 are reset and locked into the second movable groove 105 of the connecting groove 103. The stable connection of the car body panel is completed by utilizing the fishtail middle structure and symmetrical design of the outer shell 1.
