Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a bicycle generator, and particularly relates to an improvement in the structure of the power extraction portion of a bicycle generator of the type that supports both rollers.

(b) Prior Art In the conventional bicycle generator Da of the dual roller support type, as shown in Figs. 6 and 7, the lead wire 37a from the spindle is connected to the outside through the arm bracket, the cap set plate, the nut 3a and the cap 8a. I was pulling it out.

(c) Problems to be solved by the invention In the bicycle generator Da, the arm bracket, cap set plate, nut 3a, and cap 8a are small parts, and the work of passing the lead wire 37a through them is extremely complicated. There was a problem. In particular, it took time and skill to incorporate it into the cap 8a.

In addition, since the electrical connection of the lead wire 37a used a male-female joint, the headlight
There was a problem that it was difficult to connect multiple electrical connections such as tail lights.

This invention has been made in view of the above circumstances, and is intended to provide a bicycle generator in which the power extraction part on the lead wire side can be easily assembled and a plurality of power sources can be extracted.

(d) Means for solving the problem This invention connects the lead wire from the spindle to a lead plate, uses this lead plate as a current cutoff plate, and takes out a terminal spring that is elastically electrically connected to this lead plate. This is a bicycle generator that uses electrodes.

The detailed structure consists of a dynamo body, a spindle for supporting the dynamo body, which is attached to the bottom of the dynamo body in a downwardly extending state, has a cylindrical shape and has a male thread on its outer surface, and an insertion hole through which the spindle is inserted through the bottom. A dynamo holder large has a hole and fixes and holds the dynamo body by screwing a spindle and nut through the insertion hole, a fender that is integrated with the dynamo holder large and supports the upper part of the dynamo body, and a dynamo holder large. A double roller support type bicycle generator comprising a dynamo holder fixed to a bicycle body, a first recess into which the nut can be fitted around the insertion hole in the large dynamo holder, and the first recess. A second recess is formed below which is electrically connected to the lead wire extending from the inside of the spindle to the outside, and serves as a relay distribution board, into which a plate-shaped lead plate having an electrical connection dowel can be fitted in an insulated state; The nut is fitted into the first recess, the lead plate is fitted into the second recess, and is covered and fixed with the lower case, and
The lower case holds the other end of a terminal spring, which serves as an external terminal and has one end protruding outside the lower case, in an elastically electrically connected state to the dowel of the lead plate within the lower case. This is a bicycle generator featuring:

(E) Function The lead wire from the spindle is electrically connected to the lead plate of the dynamo through the insertion hole of the holder large and the nut.

The terminal spring can be connected to multiple lead wires for power extraction.

(f) Examples This invention will be described in detail based on examples shown in FIGS. 1 to 5. However, this invention is not limited thereby.

The bicycle generator D is as shown in Figures 1 to 5.
Pass the spindle 33 provided on the dynamo body 2 through the insertion hole 36 of the dynamo holder large 1 and insert the nut 3.
The dynamo main body 2 is fixedly supported on the dynamo holder large 1 by screwing into the spindle 33.

FIG. 2 shows the assembly structure of the electricity extraction portion on the lead wire 37 side of the bicycle generator D. The spindle 33 is inserted into the insertion hole 36 of the large dynamo holder 1 and screwed into the nut 3. At this time, the nut 3 is formed in the lower part of the insertion hole 36 in the large dynamo holder 1, and is located in a first recess 34 into which the nut 3 can be fitted. Next, a plate-shaped lead plate 5 which serves as a relay distribution board and has hemispherical dowels 6 for electrical connection is integrated with the insulating plate 4. Plate 4 and lead plate 5
Integration with the plate 4 is accomplished by passing the protrusion 14 of the plate 4 through the hole 13 of the lead plate 5, and then caulking the protrusion 14. 17 is the caulking part. Further, when the plate 4 and the lead plate 5 are integrated, the cylindrical portion 16 of the plate 4 is inserted into the hole 15 of the lead plate 5.
Here, the plate body consisting of the integrated plate 4 and lead plate 5 is placed in the second recess 35 of the large dynamo holder 1. Then, by screwing the end of the lead wire 37 to the lead plate 5 with a set screw (not shown), the lead wire 37
and the lead plate 5 are electrically connected. Second
The recess 35 is formed continuously below the first recess 34, and allows the lead plate 5 to be fitted in an insulated state. The arrangement of this plate body is based on the recess 11 of the plate 4 and the dynamo holder large 1.
The position of the plate body relative to the dynamo holder 1 is determined by the fitting of the convex portion 10 . The terminal spring 7 as an external terminal is connected to one end 3.
9 through the hole 38 of the lower case 8.
The lower case 8 is placed on the dynamo holder large 1 so that the recess 11 is located on the protrusion 10. Here, when the screw 9 is passed through the hole 40 of the lower case 8, the screw 9
passes through the plate 4 and the cylindrical portion 16 and is screwed into the female threaded portion 18 of the large dynamo holder 1. Here, the lower case 8 is fixed to the dynamo holder large 1. Also, plate 4 and lead plate 5
The plate body consisting of is pressed upward by the lower case 8 and fixedly held within the second recess 35. Furthermore, at this time, terminal spring 7
The other end is electrically connected by contacting the dowel 6 of the lead plate 5 and is electrically connected to the lead wire 37 .

In this way, since the lead wire 37 only needs to be passed through the insertion hole 36, the nut 3, and the plate body,
Assembly work is simple and not complicated. Further, when extracting electricity, the terminal spring 7 can be connected to a plurality of lead wires. Furthermore, since the positional relationship between each part is clear, assembly can be performed without mistakes. Electricity is taken out not by lead wire but by terminal spring 7
It also looks good on the outside.

19 is a dynamo holder, and a sleeve 21 and a sleeve 2 are placed in the recess 20 of the dynamo holder large 1.
Dynamo holder large 1 inserted through 2
Become one with. The dynamo holder 19 is for fixing the dynamo holder large 1 to a bicycle body, for example, to a bicycle frame. Spring 23 attached around dynamo holder 19
has one end engaged with the dynamo holder 19,
The other end is engaged with the dynamo holder large 1. This urges the dynamo holder large 1 toward the bicycle tire. The working lever 25 rotates around a boss 26 that projects downward from the bottom surface of the large dynamo holder 1. One end of a spring 27 for preventing the working lever 25 from coming off is passed through the boss 26.
The other end of the working lever 7 is locked to a locking piece 28 formed on the working lever 25. When the bicycle generator D stops generating electricity, as shown by the solid line in FIG. 25 is engaged with the dynamo holder 19 at a portion 29. When the bicycle generator D is placed in a power generation state, the engagement between the dynamo holder 19 and the portion 29 of the working lever 25 is released, as shown by the dashed line in FIG. That is, the working lever 25 is rotated clockwise with respect to the dynamo holder 19 fixed to the bicycle body. An operating knob 30 is set on the working lever 25.

31 is a fender, which is fixed to the dynamo holder large 1 with screws 32.

(g) Effects of the invention The bicycle generator according to this invention, as described above, electrically connects the lead wire extending from the inside of the spindle to the outside to the lead plate of the relay distribution board, and electrically connects it to the lead plate. Since electricity is taken out from a terminal spring serving as an external terminal, assembly is simple and a plurality of lead wires for taking out electricity can be connected.
