Abstract
The utility model relates to a disk type generator for bicycles. The utility model is formed by the way that a static disc provide with magnetic conductivity and a magnetic conductivity movable disc which can do corresponding movement with the static disc are connected by using rolling bearings. One disc is fixed with a permanent magnet, while the other disc is fixed with an induction coil and an iron core. The generator can be fixedly arranged on a bicycle axle position through the static disc or is fixedly arranged on bicycle wheels through the movable disc. The generator has the advantages of no abrasion to the bicycle, no resistance of riding, no noise, convenient installation and reliable and durable use.
Description
The utility model relates to a kind of employing magnetic energy conversion, is used for illumination and decoration generator on the bicycle.
Existing bicycle dynamo all is certain position that is fixed on cycle frame, generate electricity from the wheel acquisition power that rotates by the friction tire or with transmission mechanism, what have needs some special part of increase to reach installation in order to install and to use, the purpose of transmission or increase rotating speed, the generator of these forms makes the cycling resistance big, tire chafing is serious, rainy day skids and the shakiness of working, the operation noise is all arranged during work, they are difficult to electric energy easily and reliably in addition, be delivered to enduringly on the cycle wheel of rotation, thereby can't light the safe decorative lamp that is installed on the vehicle wheel spoke reliably.
The purpose of this utility model is that design a kind ofly links up a static disk and the rotary disk with magnetic conductivity that does relative motion with static disk with magnetic conductivity with rolling bearing, constitutes a bicycle disc generator.
The purpose of this utility model is finished with following form: a static disk A and the rotary disk B who does relative motion with static disk with magnetic conductivity is linked up with rolling bearing (10), constitute a generator, generator is installed on the axletree or chassis assembly of bicycle by static disk A.Sheet permanent magnet (12) is housed on static disk A, induction coil (2), iron core (13), interlock driving lever (3) are housed on rotary disk B.According to the needs in people's use, also induction coil (2) iron core (13) can be installed on the static disk, the sheet permanent magnet also is fixed on the rotary disk B.The utility model provides a kind of new bicycle disk generator, and it does not increase riding resistance, and noiselessness does not have wearing and tearing to bicycle, does not do any change on the existing bicycle, does not increase any part and just can install and use.
Below in conjunction with accompanying drawing the utility model is described further.
Figure 1A is the end view of the static disk of the utility model, and B is the end view of rotary disk.
Fig. 2 is the installation position schematic diagram of the utility model on bicycle.
Fig. 3 is installed in position cutaway view on the bicycle for the utility model.
With reference to Figure 1A, at static disk A upper edge circumference with magnetic property with bonding method or with bolt quantity to be arranged be the several block sheets shape permanent magnet (12) of even number, in the present embodiment, the quantity of flaky magnet is 12, the magnetic pole of 12 blocks of permanent magnets is towards the one side of static disk or the one side of disk dorsad on big face, if that is to say that any N in 12 blocks of magnet is extremely towards the one side of disk, its S utmost point one side of disk dorsad just so, otherwise if the S pole-face is to the one side of disk, its N utmost point one side of disk dorsad just so.The arrangement of such 12 blocks of magnet is according to N shown in Figure 1A, S, N, S ... arrangement is gone down.Between each magnet, leave and the corresponding neutral gear of induction coil core dimensions.Be fixed on the rotary disk B with magnetic conductivity by circumference 12 five equilibriums with riveted joint or bolt with reference to Figure 1B, induction coil (2) and iron core (13).The number of induction line chart and series connection coupling method still in parallel is the needs calculating decision according to light fixture.With reference to Fig. 3, with static disk A (11) and the rotary disk B (1) that assembles, be separately fixed on interior connecting flange (9) and the outer attached method orchid (4) with bolt, interior connecting flange (9) uses rolling bearing (10) to be connected again with outer attached method orchid (4).The one side that is fixed with magnet (12) on the one side that is fixed with coil (2) and iron core (13) on the rotary disk B (1) and the static disk A (11) is relative, interlock driving lever (3) riveted joint or be fixed on the one side that rotary disk B (1) goes up and induction coil (2) is opposing with screw thread.The generator that assembles is installed between axletree shelves (6) and the vehicle frame (8) by static disk A (11), and is fixed with locator card (7).The safe decorating lamp bulb that links up with lead also is installed on the vehicle wheel spoke in addition, and induction coil output and bulb connecting conducting wire join.When bicycle walking, vehicle wheel spoke (5) is stirred interlock driving lever (3), drives induction coil on the Moving plate and the permanent magnet on the quiet dish and does relative motion and induce electric current, passes to safe decorative lamp on the wheel by lead.Use the same method and induction coil (2) and iron core (13) can be fixed on the static disk A, permanent magnet (12) is fixed on the rotary disk B, and the electric current that induces when rotary disk B rotates with bicycle quick can be used for the bicycle running illumination.The generator that assembles can also be fixed on the vehicle wheel component with bolt by rotary disk B (1), interlock driving lever (3) also is fixed on the static disk A, be positioned at one side with locator card (7), when wheel drives the generator rotation, locator card (7) and interlock driving lever (3) limit static disk A rotation jointly, and rolling disc B and static disk A are done relative motion and induced current.
The quantity of permanent magnet (12) can increase and decrease according to purposes.Be mainly used in when decorating, magnet quantity can be less, and the induced current frequency is low like this, and light produces flicker, and decorative effect is better.Be mainly used in when illumination, magnet quantity can be some more, induced current frequency height like this, and light is stablized.
Claims (4)
1. bicycle disc generator is characterized in that linking up static disk A and the rotary disk B with magnetic conductivity that does relative motion with static disk A of having magnetic conductivity to one with rolling bearing (10), constitutes a disk generator.This generating function is installed on the axletree or chassis assembly or vehicle wheel component of bicycle.
2. according to right 1 described bicycle disc generator, it is characterized in that described static disk A goes up suitable circumferencial direction arrangement and is fixed with some blocks of permanent magnets (12), be fixed with the induction coil (2) and the iron core (13) that equate with permanent magnet (12) quantity on the Moving plate B.
