Description

Technical Field

[0001] The utility model relates to the technical field of magnetos, in particular to a magneto coil for a motorcycle. Background Art

[0002] A magneto is a small AC generator device, mainly used in motorcycles, to supply power to the ignition system in the motorcycle for starting the motorcycle engine. The main components in the magneto are a coil and a magnet. It mainly utilizes the principle of electromagnetic induction. When the magnet rotates, a changing magnetic field is generated, which cuts the magnetic lines of force in the stationary coil, thereby generating an induced electromotive force in the coil. This voltage can be used to supply power to the motorcycle ignition system.

[0003] In the prior art, the coil on the magneto is generally fixed in the housing by bolts. The coil includes components such as an iron core, a terminal post, and a winding group. Among them, the terminal post is fixed on the iron core, and some are integrally provided with the iron core. Then the winding group is wound on the surface of the terminal post. Since the terminal post and the winding group are prone to burning out during use, and because the terminal post is integrally provided with the iron core, once it is burned out, the entire coil can only be replaced, which leads to an increase in cost and waste of resources.

[0004] Therefore, how to provide a magneto coil for a motorcycle is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] An object of the utility model is to provide a magneto coil for a motorcycle. The utility model solves the problem that in the prior art, once the terminal post and the winding group are burned out, the entire coil can only be replaced, resulting in an increase in cost and waste of resources.

[0006] A magneto coil for a motorcycle according to an embodiment of the utility model includes an iron core, a terminal post, and a winding group. The winding group is wound on the surface of the terminal post. A slot is opened at the connection between the outer side surface and the front surface of the iron core. An insertion block is movably inserted into the slot. One end surface of the insertion block located outside the iron core is fixed to the terminal post. A clamping groove is opened at a position close to the front surface of the iron core inside the slot. A positioning component is arranged at a position corresponding to the clamping groove inside the slot. One end of the positioning component is inserted into the clamping groove and is clamped with the clamping groove.

[0007] The number of the slots is one or more. One or more slots are distributed in a circular array with the axis of the iron core as the array center. The number and positions of the insertion blocks match the number and positions of the slots.

[0008] The shape of the slot is "convex" - shaped, and the shape of the insertion block is the same as that of the slot.

[0009] The number of clamping grooves corresponding to each slot is two. The two clamping grooves are symmetrically arranged with the symmetry axis of the slot as the symmetry axis.

[0010] The positioning component includes a positioning block having the same shape as the slot and two clamping blocks. The positioning block is movably disposed inside the slot and abuts against the surface of the insertion block. A through groove that penetrates the entire positioning block is provided at the position of the positioning block corresponding to the card slot. A limiting groove that communicates with the through groove is formed on the side of the positioning block away from the insertion block. The width and length of the limiting groove are smaller than the length and width of the through groove. The two clamping blocks are both movably disposed at the two openings of the through groove. The departing ends of the two clamping blocks are docked with the card slot. A spring member is disposed between the two clamping blocks. The spring member is movably disposed inside the through groove. A paddle is movably disposed inside the limiting groove. One end of the paddle is fixed to the surface of the clamping block.

[0011] The side of the positioning block away from the insertion block is in the same plane as the front surface of the iron core.

[0012] The beneficial effects of the present utility model are:

[0013] By providing the slot and the insertion block, with the slot located on the outer side surface of the iron core and the insertion block inserted into the slot, it is convenient to remove the insertion block from the slot, thereby independently removing the wire column to replace the wire column that needs to be replaced, achieving the effect of independently designing the wire column to facilitate the removal of the wire column, and solving the problem in the prior art that only the entire coil needs to be replaced when the wire column and the winding group are burned out, resulting in increased costs and waste of resources.

[0014] By providing the positioning component, the positioning component is stuck in the card slot to position the insertion block inserted into the slot, so that the insertion block is positioned in the slot, thereby improving the stability of the insertion block and preventing the insertion block from automatically separating from the slot.

[0022] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.

[0023] Reference Figure 1 、 Figure 3 and Figure 4 , including an iron core 1, a wire post 2 and a winding group 3. The winding group 3 is wound on the surface of the wire post 2. A slot 4 is provided at the connection between the outer side surface and the front surface of the iron core 1. The number of slots 4 is one or more, and one or more slots 4 are annularly arranged with the axis of the iron core 1 as the array center. Such a distribution is very uniform, making the distance between the plug 5 and the wire post 2 the same. The shape of the slot 4 is "convex" - shaped. Such a design can stably hold the plug 5 in the slot 4. The plug 5 is movably inserted into the slot 4. The number and position of the plugs 5 match the number and position of the slots 4. The shape of the plug 5 is the same as that of the slot 4. The side surface of the plug 5 is closely attached to the inside of the slot 4. This is to reduce the gap and avoid shaking during normal use. One end surface of the plug 5 located outside the iron core 1 is fixed to the wire post 2. When it is necessary to independently remove the wire post 2, first, the positioning component 7 needs to be removed, and then the plug 5 is moved along the slot 4 towards the front surface direction of the iron core 1. In this way, the plug 5 will slowly move in the slot 4 until it is separated from the slot 4. The separation of the plug 5 from the slot 4 can drive the wire post 2 to be independently removed, so that the wire post 2 can be removed from the iron core 1, facilitating the replacement of a single wire post 2 and the winding group 3, reducing the use cost and avoiding waste of resources;

[0024] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5, a card slot 6 is provided inside the slot 4 near the front position of the iron core 1. The number of card slots 6 corresponding to each slot 4 is two. The two card slots 6 are axially symmetrically arranged with the symmetry axis of the slot 4 as the axis of symmetry. Such a symmetrical arrangement can make the positioning component 7 receive balanced force and make the positioning of the plug 5 more stable. A positioning component 7 is arranged inside the slot 4 corresponding to the position of the card slot 6. One end of the positioning component 7 is inserted into the card slot 6 and is engaged with the card slot 6. The positioning component 7 includes a positioning block 8 having the same shape as the slot 4 and two clamping blocks 9. The positioning block 8 moves inside the slot 4 and fits on the surface of the plug 5. The side of the positioning block 8 away from the plug 5 is in the same plane as the front surface of the iron core 1, avoiding protrusion and affecting use and aesthetics. A through slot 10 that penetrates the entire positioning block 8 is provided at the position of the positioning block 8 corresponding to the card slot 6. A limiting slot 11 that communicates with the through slot 10 is provided on the side of the positioning block 8 away from the plug 5. The width and length of the limiting slot 11 are smaller than the length and width of the through slot 10. Since the length and width of the limiting slot 11 are both smaller than those of the through slot 10, and the size of the clamping block 9 in the through slot 10 matches that of the through slot 10, the clamping block 9 can be limited in the through slot 10 and can only move inside the through slot 10, improving the movement stability. The two clamping blocks 9 are both movable at the two openings of the through slot 10. The opposite ends of the two clamping blocks 9 are docked with the card slot 6. A spring member 12 is provided between the two clamping blocks 9. Since the width of the limiting slot 11 is smaller than that of the through slot 10, the spring member 12 can also move stably inside the through slot 10 under extrusion. The spring member 12 moves inside the through slot 10. A dial 13 moves inside the limiting slot 11. One end of the dial 13 is fixed on the surface of the clamping block 9. The dial 13 is used to drive the clamping block 9 to move. When the positioning component 7 needs to be removed, pinch the dial 13 with fingers and force the dials 13 to approach each other. The dials 13 approaching each other will drive the clamping blocks 9 to approach each other and squeeze the spring member 12. The clamping blocks 9 approaching each other will separate from the card slot 6, and then move the positioning block 8 towards the front surface of the iron core 1 to separate it from the slot 4, so that the positioning component 7 can be easily removed, and then the plug 5 can be operated. When the positioning component 7 needs to be installed, only the above method needs to be operated in reverse. Since there will inevitably be a gap between the positioning block 8 and the plug 5 during clamping, in order to improve the stability of the plug 5 and the positioning block 8, a rubber pad is provided on the side where the positioning block 8 fits the plug 5. The rubber pad squeezes the plug 5 and the positioning block 8, avoiding collision between the plug 5 and the positioning block 8 and also improving the connection stability of the plug 5.
