[0014] The technology of the present invention will now be described with reference to the accompanying drawings of the embodiments thereof. The solution is described clearly and completely. Obviously, the described embodiments are only a part of this utility model. This is a partial embodiment, not all embodiments. Based on the embodiments in this utility model, those skilled in the art... All other embodiments obtained by those skilled in the art without inventive effort are part of this invention. The scope of protection of utility models.
[0015] Please refer to Figures 1-5, a modular magnetic quick-release device for bicycles, with the main fixing base 1. It includes a base body that is generally disc-shaped or square-shaped, and the base body can be made of metal, high strength Made of engineering plastics (such as PA66+GF30) or nylon, etc., the base body has openings of up to Two fewer bolt holes are provided for the first mounting structure 101, and the hole spacing of these bolt holes is preferably consistent with the standard. The mounting hole spacing of the car's cup holder is matched (usually 64mm or 74mm), allowing the use of standard water bottles. Use cup holder mounting bolts to securely install the mounting base 1 onto the bicycle frame (usually the seat tube or down tube). On the reserved threaded hole.
[0016] A pair of locking pins 104 are provided on the upper surface of the base body (i.e., the mating surface with the movable module 2). It consists of a radially extending section and a circumferentially locking section connected thereto. At the end of the locking pin 104, a... A spring 105 acts as a limiting structure, which produces a distinct "click" when the slot 203 slides to this position and provides a backlash force to prevent rotational unlocking.
[0017] Meanwhile, at least one first magnet 103 is also embedded on the upper surface of the base body. 103 is preferably a high-performance neodymium iron boron permanent magnet. In this embodiment, two first magnets 103 are provided. They are symmetrically distributed about the center of the base body; this symmetrical layout helps to generate [properties] during docking. The uniform adsorption force guides the active module 2 to approach at the correct angle. Furthermore, within the base body... At the center position, a guide groove 102 can also be set.
[0018] The active module 2 mainly includes a module body, the shape of which can be consistent with the fixed base. The base 1 is adapted to the base, and its lower surface (i.e., the mating surface with the fixed base 1) is fixed with the locking pin 104. The corresponding slot 203 is precisely matched in position and size with the locking pin 104, so that they... It can slide in and out smoothly.
[0019] On the lower surface of the module body, a second magnet 204 corresponding to the first magnet 103 is embedded. The second magnet 204 can be a permanent magnet with the opposite polarity to the first magnet 103, so as to generate a strong attractive force; Alternatively, prioritizing cost, the second magnet 204 can be replaced with a magnetic sheet (such as a low-carbon steel sheet). The steel sheet can also generate sufficient attraction force with the first magnet 103, and the distribution of the second magnet 204... The method is also consistent with that of the first magnet 103. Correspondingly, a corresponding opening is provided at the center of the lower surface of the module body. The guide protrusion 202 that mates with the guide groove 102, the mate of the guide protrusion 202 with the guide groove 102, Based on magnetic alignment, more precise radial coarse positioning can be performed to prevent the moving module 2 from being locked. After solidification, it undergoes radial movement relative to the fixed base 1.
[0020] A second mounting structure 201 is provided on the upper part of the module body for connecting external items. Mounting structure 201 can be a standard 1 / 4-inch threaded hole (camera universal interface) for use with Action cameras, gimbals, etc., can be directly mounted. In other embodiments, the second mounting structure 201 can also be... The ball head gimbal interface, the GoPro brand-compatible snap-fit interface, or the simple 205-pin pull hole are all options. Through holes for threading straps, etc.
[0021] In another embodiment, the active module 2 is provided with a general second mounting structure 201. It is equipped with a variety of adapters, which have connection ends that match the general second mounting structure 201, as well as specific structural ends for fixing different external items.
[0022] The magnetic attraction component 3 is composed of a first magnet 103 and a second magnet 204. The rotating card... The fastening mechanism 4 is composed of the card slot 203 and the card pin 104.
[0023] Working principle: First, roughly align the active module 2 with the fixed base 1. When they are close together, the magnet... When the suction component 3 starts working, the strong magnetic force between the first magnet 103 and the second magnet 204 will attract the moving parts. Module 2 automatically attaches and is pulled into the correct position. Simultaneously, the guide protrusion 202 inserts into the guide groove 102. In this process, the initial radial positioning is completed. At this point, the slot 203 will be precisely aligned with the radial insertion of the pin 104. Section entrance.
[0024] With the assistance of magnetic force, the locking pin 104 will slide from the radial guide section of the locking slot 203 into the circumferential lock. Stop. When the movement is complete, the locking pin 104 slides into the locking slot 203, producing a clear "click" feel. This indicates that locking is complete. At this point, the magnetic component 3 continues to provide a sustained suction preload, while the rotating card... The fastening mechanism 4 bears the main longitudinal tensile force and torsional torque, forming a combination of magnetic anti-loosening and mechanical bearing. With double insurance of "force", the connection is extremely stable.
[0025] During disassembly, the user rotates the movable module 2 to overcome the slight resistance of the limiting structure, causing the locking pin to engage. 104 retracts from the circumferential locking section of the slot 203 to the radial guiding section. At this point, since the magnetic force still exists, It may require a little force to separate the active module 2 from the fixed base 1.
[0026] Users can prepare multiple activity modules 2, each equipped with a different second mounting structure 201. Alternatively, different accessories (such as lights, horns, etc.) can be pre-installed. This way, during the ride, you can... It can switch parts within seconds according to needs, achieving true modularity and multi-functionality.
