Description

A kind of magnetic control brake structure

Technical field

The utility model relates to a kind of magnetic control brake structure, particularly a kind of magnetic control brake structure of fitness equipment.

Background technology

At present commercially available various fitness equipment gradually all adopts stable higher magnetic control means, as the setting that changes resistance of motion size, it is by the size of adjusting magnetic gap, has the function that to set its resistance power as multisection type to reach, though the structural configuration of such magnetic control means is various, but still there is its part that haves much room for improvement in design in numerous magnetic control means, therefore, most products are adjusted before dispatching from the factory and are set in the operation, except the assorted difficulty of step, outside consuming time, often still can't reach the regulation that makes this device meet A level sport(s) car among the European consumed power safety standard EN-957-5.Moreover, before the narration conventional construction, the reason that need adjust with regard to magnetic control means earlier is illustrated, be because magnetic support when depanning and all can cause the distortion of its certain degree in the process of processing, therefore magnetic control means is designed to the mechanism of adjustable, can adopt by the tester measured value and revise the requirement that reaches safety to meet at random, promptly each section setting value of multisection type magnetic control means all can meet in the consumed power error amount of standard code.

Check and approve case as the Taiwan patent, announce No. 254111 " the magnetic control brake structure of sport(s) car ", it is below the resistance wheel of this sport(s) car, with the pedestal book office holder that locks, holder one side chain connects one and can go up, mobile down magnet assemblies, the bottom of this magnet assemblies is provided with a magnetic receiver, be installed with several magnet on the magnetic receiver, and set firmly a motor at the opposite side of holder, the relative edge appropriate position of motor is provided with microswitch, the locating wheel wheel rim pressing that this microswitch and motor drove is characterized in that: this magnet assemblies is provided with one group of corresponding pivot ear at its magnetic receiver interlocking in another side bottom surface book office of holder; One transmission mechanism, be to establish a cam at the ring edge sleeve of an eccentric wheel, this cam apical margin is hubbed at the pivot ear place of magnetic receiver, eccentric wheel card near-ring rim is established a hollow cylinder, this hollow cylinder runs through from one of eccentric wheel side and extends to opposite side, and ring is provided with negative thread in week in it, and the one end is to be bolted on the eccentric output shaft of motor, and the other end is this locating wheel of interlocking then.

Aforementioned structure promptly is a kind of magnetic control means of adjusting the damping power, it drives cam indirectly by the motor transmission, make the magnetic receiver that is linked to cam point can make the function of synchronous shift, it is the device of setting for a kind of section speed of controlling the magnet controlled damping size, this structure is if desire is set the consumed power value of " benchmark ", only mode, only can with adjust whole group holder be locked on pedestal to the position, and list is difficult to reach standard in the above described manner, its principal element is, aforementioned mentioning because magnetic support has resilience to a certain degree when depanning, and in the process of Surface Machining, also can make the bent radian of each magnetic support different, therefore, each is equiped with the exercycle of magnetic control brake structure, must be less than ± 10% with interior error criterion if want desire to meet the consumed power (being wattage) of A level regulation among the European safety EN-957-5; And the shortcoming of known adjustable magnetic control brake structure, be to produce comparatively accurate consumed power value to set at all, main cause is: after whole group magnetic control brake structure device is finished, the rotatable peak position of cam and the relative coupling position of magnetic receiver, be to belong to the mode of being completely fixed, can't remake the fine setting design of thin portion, add and connect the eccentric wheel outboard end of establishing for cam and adopt the blocking mode and be connected with a locating wheel, and this locating wheel touches device in its wheel rim subsides factors such as a microswitch, make each member of magnetic control brake structure in case after assembling location finishes, just can't remake the fine setting of relevant position, therefore, when just the stage desire is set the relative datum position of magnetic receiver and resistance wheel, no matter the bent arc of magnetic receiver change have much, also only can with the mode of range estimation as far as possible by the displacement holder be installed in exercycle pedestal relative position and change, by easy single mode, be the standard setting that at all can't make accurate mistake value.

The utility model content

The utility model is the problem that will solve the standard setting that can't make the accurate error amount of power of existing magnetic control brake structure existence, can accurately adjust reluctance force magnetic control brake structure size, that meet European safety A level codes and standards and provide a kind of.

The utility model includes the magnetoresistive devices in the installing of resistance wheel one side of exercycle, and this magnetoresistive devices is to be made of an arc magnetic support and side is installed with within magnetic support is with respect to resistance wheel several magnet; It is characterized in that: the end is hubbed on a located lateral plate one end with an axostylus axostyle on this magnetic support, make this magnetic support can be by the articulated section of upper end as a moving fulcrum, this location-plate in addition end is formed with two circular holes, can place for lock member to revolve locking bit and be set up in vertical plate body of exercycle pedestal; End one side is extended with a pipe box under this magnetic support, places binding for a connecting rod;

This connecting rod one end is provided with thread segment, and end is hubbed on the rocking arm of transmission device in addition; After thread segment penetrated pipe box, each screw lock had a nut in the both sides of pipe box, being linked to the position of pipe box relatively as adjusting connecting rod, and then reached the width size between fine-tuning magnetic support bottom and resistance wheel;

This transmission device comprises the motor that is installed on the pedestal, and a rocking arm that is pivoted at the power transmission shaft place of motor.
