Problems solved by technology

[0009] In addition, the holding member 102, the detection unit 103, etc. of the vehicle speed detection device 100 may come into contact with an adjacent bicycle or an upright pole (pole) or the like to be damaged when the bicycle is parked or moved.
In addition, since the holding member 102 and the detection unit 103 are exposed to the outside, there is also the possibility of mischief by remodeling the holding member 102 and the detection unit 103 .

Embodiment Construction

[0037]Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in this embodiment, a power-assisted bicycle is described as an example of a bicycle equipped with a vehicle speed detection device, but the present invention is not limited to a power-assisted bicycle and can be applied to various bicycles. In addition, the structure of this invention is not limited to the structure described below. In addition, the left-right direction and the front-rear direction in the following description refer to the direction in the state in which the motor-assisted bicycle 1 is mounted toward the traveling direction.

[0038] figure 1 Among them, 1 is an electric assist bicycle as an example of a bicycle. This electrically assisted bicycle 1 includes: a vehicle body 2, a front wheel 3, a rear wheel 4, a chain 6 as a driving force transmission body for transmitting the pedaling force (human driving force) of the pedals 5 to the rear...

Abstract

The present invention provides a bicycle speed detection device that can prevent the device from being damaged due to contact with a guide frame of a parking device or an adjacent bicycle, and can also minimize modifications. The vehicle speed detection device (8) of the vehicle has a hub shaft (24) fixed to the frame body (12), and a hub rotatably provided at the center of the front wheel relative to the hub shaft (24) and rotating integrally with the front wheel. (23), a plurality of magnets (31) as a magnetic generating body that generates magnetism, and a reed switch (32) as a detection body that detects the magnetic change of the magnet (31) in order to detect the vehicle speed, wherein the magnet (31) and The reed switch (32) is arranged inside the hub (23), the magnet (31) is fixed on the hub (23) side, and the reed switch (32) is fixed on the hub shaft (24) side.

Description

technical field [0001] The present invention relates to a vehicle speed detection device for detecting the running speed of a bicycle and a bicycle provided with the vehicle speed detection device. Background technique [0002] Conventionally, as a vehicle speed detection device for detecting the running speed of a bicycle, there is a device that detects magnetic fluctuations caused by a plurality of magnets that rotate together with the wheels, and obtains the running speed based on the fluctuations. Such a vehicle speed detection device is disclosed in Patent Document 1, for example. like Image 6 As shown, this vehicle speed detection device 100 has: a substantially disk-shaped holding member 102 holding a plurality of magnets 101 along the circumferential direction; Part) 103. [0003] like Image 6 , Figure 7 As shown, the holding member 102 is made of a substantially disk-shaped resin member, and is assembled on the outer side (side) of the spoke 105 near the axial...
