A gas spring mounting structure and connection structure, and a device having an opening and closing mechanism are disclosed. The gas spring mounting structure is used to connect the gas spring to the opening and closing mechanism. The first end of the gas spring is used to connect to the housing of the opening and closing mechanism. The gas spring mounting structure includes: a first support member with a first end face and a first hole in the first end face; a second support member with a second end face and a second hole corresponding to the first hole in the second end face; and a first threaded fastener, which is embedded in the second support member and the first support member through the second hole and the first hole to realize the disassembly and locking of the first support member and the second support member. The first threaded fastener is used to reduce the gap between the second support member and the first support member during the locking process, thereby gradually pre-tightening the gas spring. Furthermore, due to the existence of the gas spring mounting structure, no additional gas spring mounting fixture is required, avoiding the influence of the superposition of the tolerances of the fixture and the gas spring on the installation accuracy.

This invention relates to the field of commercial vehicle steering column technology, specifically disclosing an adjustment structure for a commercial vehicle steering column. The structure utilizes an angle adjustment component to drive the steering column body to rotate, and a sliding fit structure between a sliding seat and a sliding groove allows the steering column body to achieve a large rotational stroke under the drive of the angle adjustment component. Specifically, the angle adjustment component employs a lead screw drive structure. A first driving member drives a first lead screw to extend and retract, thereby pushing the steering column body to rotate around its hinge point. Because the first lead screw has a long extension and retraction stroke, and the lever arm between the hinge point of the steering column body and the connection point of the angle adjustment component can be optimized to a shorter distance, a small extension and retraction of the lead screw can be converted into a large angle change. Simultaneously, the longer first lead screw stroke further amplifies the angle adjustment range to adapt to different driving needs and driver maneuverability.

This invention provides an edge-plugging connection system for modular toys and its construction method. The system includes at least two assembly modules, each with an edge face featuring an opening and a plugging space. Adjacent assembly modules interlock via their respective edge face plugging structures, with the inner wall of the plugging space forming a surface contact with the corresponding module's plate and edge face, achieving multi-directional rigid constraint and self-supporting detachable connection. After multiple modules are sequentially plugged in, the supporting contact surfaces connect along the structural extension direction to form a continuous force path, allowing external loads to be transmitted and dispersed in an orderly manner along this path, forming a self-stabilizing spatial structure system that can be constructed as a load-bearing structure, climbing structure, or dynamic movable structure. This invention achieves multi-directional rigid constraint, stable force transmission, and strong load-bearing capacity solely through its own structure, solving the problems of discontinuous force transmission paths and insufficient self-stability caused by existing technologies relying on additional connectors or elastic clamps.
