Abstract

The utility model relates to a generator for bicycle decoration and lighting, comprising a stationary disc with the magnetic conductivity and a rotary disk with magnetic conductivity, wherein, the rotary disk is capable of moving relatively to the stationary disc. One disc is fixed with a permanent magnet, and the other disc is fixed with an induction coil and an iron core. The stationary disc and rotary disc are respectively fixed on the axles and the wheels of a bicycle; no driving member is in the generator without direct mechanical contact, so the utility model has no abrasion and no noise for the bicycle consumption, convenient installation, and reliable and permanent use.

Description

Generator for bicycle decoration and lighting

The utility model relates to a kind of employing magnetic energy conversion, is used for decoration and lighting generator on the bicycle.

Existing bicycle dynamo all is the inseparable total member of a kind of monolithic devices, be fixed on certain position of cycle frame, generate electricity from the wheel acquisition power that rotates by the friction tire or with transmission mechanism, the generator of this form makes that the cycling resistance is big, tire chafing is serious, and what have also need increase some special part in order to install.So generator all has the operation noise, the more important thing is that they are difficult to electric energy is delivered on the cycle wheel of rotation easily and reliably, enduringly, thereby can't light the decorative lamp that is installed on the vehicle wheel spoke reliably.

The purpose of this utility model is a kind of split type generator of bicycle with the static disk of magnetic conductivity and rotary disk formation that static disk is done relative motion of design.

The purpose of this utility model is finished with following form: it is that a static disk A with magnetic conductivity and one constitute with the magnetic conductivity rotary disk B that static disk A does relative motion, wherein stationary disk A is installed on the axletree or chassis assembly of bicycle, rolling disc B is installed on the vehicle wheel component of bicycle, sheet permanent magnet (3) is housed on static disk A, induction coil (1), iron core (2) are housed on the rolling disc B.According to the needs in people's use, also induction coil (1) and iron core (2) can be installed on the static disk A, sheet permanent magnet (3) also is fixed on the rolling disc B.

The utility model provides a kind of novel split type generator of bicycle, do not have driving member, wearing and tearing moving part and quiet, do not have direct Mechanical Contact, thereby do not have mechanical wearing and tearing, noiselessness, do not increase the bicycle walking resistance, on existing bicycle, do not do any change, do 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, the magnetic pole that six blocks of permanent magnets (3), six blocks of permanent magnets are arranged with bonding method or with bolt at the static disk A upper edge circumference with magnetic property is towards the one side of static disk or the one side of disk dorsad on big face, that is to say if any one N pole-face is to the one side of disk in six blocks of magnet, so the S utmost point one side of disk dorsad just.Otherwise if the S pole-face is to the one side of the disk N utmost point one side of disk dorsad just so.Putting in order of such six blocks of magnet 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.With reference to Figure 1B, induction coil (1) and iron core (2) are halved by circumference ten with riveted joint or bonding method and are fixed on the rotary disk A with magnetic conductivity.The number of induction coil and the series connection method that connects still in parallel is the needs calculating decision according to decorating lamp bulb.The static disk A that assembles is installed between axletree shelves and the vehicle frame, and the one side that is fixed with magnet is inside, and welding of stationary disk another side or riveted joint have locator card (6), makes stationary disk and vehicle frame add one by locator card (6) and fixes.Rotary disk B is fixed on the spoke (5) of bicycle quick, makes an end face that has induction coil relative with the end face that stationary disk has magnet.In addition, the fixing live wire decorating lamp bulb of contacting also on the spoke, the output of induction coil and bulb connecting conducting wire join, at this moment when bicycle walking, wheel, drive induction coil on the Moving plate and the permanent magnet on the quiet dish and do relative motion, and induce electric current, pass to decorative lamp on the wheel by lead.Use the same method and induction coil (1) and iron core (2) can be fixed on the static disk A, permanent magnet pieces (3) is bonded on the rotary disk B, and the electric current that induces when rolling disc B rotates with bicycle quick can be used for the bicycle lighting lamp.

Claims

1, a kind of bicycle decorative lighting generator, it is characterized in that it is made of the magnetic conductivity rotary disk B that a static disk A with magnetic conductivity and and static disk are done relative motion, wherein rolling disc B is installed on the vehicle wheel component of ordinary bicycle, and stationary disk A is installed on the axletree or chassis assembly of bicycle.

2, bicycle decorative lighting generator according to claim 1, it is characterized in that described static disk A goes up suitable circumferencial direction arrangement and is fixed with 4---12 blocks of permanent magnets (3), Moving plate are provided with and corresponding induction coil of permanent magnet (3) (1) and iron core (2).

3, mark 1 described bicycle decorative lighting generator according to right, it is characterized in that to be fixed with induction coil (1) and magnetic core (2) on the described static disk A, can be fixed with permanent magnet (3) on the rotary disk B.
