該支架11是料該自行車（圖未示）的—車輪2遠離地 面，使該車輪2在踩踏過程中原地轉動。該阻力裝置12具 有設置在該支架U的-輪座121、設置在該輪座i2i間且 與忒自行車車輪2接觸的一阻力輪122、沿一軸線方向貫穿 該輪座m與該阻力輪122的一輪轴123、套固在該輪轴 =3 —穿出段且位於該輪座121 一側的一感應件124,及固 設在該輪i 121 一側且環繞該感應件124等距分佈的數磁 性體125 〇 _ 由於該自行車車輪2是抵靠在該阻力輪122上，因此 ，當該車輪2迴旋轉動時，會帶動該阻力輪122轉動，使 與該阻力輪m同軸的感應件124同步旋動，並在旋動過 程中，受該等磁性n 125的磁力影響，產生阻滯效果，所 以，騎乘者必須施力踩踏，才能使該車輪2轉動，藉此， 達到運動效果。 惟，該等磁性體125與該感應件124的間距，會影塑 磁阻的大小，因此，在該等磁性體125與該感紹牛124 ^ 距固定的情形下，所能產生的磁阻也就沒有變化，但是， 1273915 通常需要耗用較大的踩踏力 就會因為慣性及離心力作用 作變得較不費力，此時，運 該自行車車輪2最初起動時， ，隨著該車輪2轉速的提昇， ，而克服部份阻力，使踩踏動 動效果也會大打折扣。 【發明内容】 的自行車用訓練器。 一種能改變阻力大小 於是，本發明的自行車用訓練 裝置、-感應組，及—驅動件。兮“ 3 h 一阻力 -車Μ雜“.勤件。该支架是撐架該自行車的 對^ 1 ^ 有樞設在該支架上且可相 ^ ^ . 座、樞故在該輪座上且與該自 ^ 輪及沿一軸線方向貫穿該輪座與 吞亥阻力輪的一於產山。姑4由 、 门 两 Μ組具有沿該軸線方向與該輪座 相隔固定間距的一第一威處 弟感應件，及與該輪軸同步轉動且可 沿該輪轴相對該第—感應件位移的一第二感應件，該第一 、、弟二感應件間產生有磁性吸力。該驅動件是隨著該輪軸 迴轉速度的增加’推動該第二感應件縮小與該第一感應件 的間距。 本發明的功效是能隨著迴轉速度增加，增大阻滯力， 使％乘者確實達到運動效果。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 、下配5參考圖式之一個較佳實施例的詳細說明中，將可 清楚的呈現。 1273915 芩閱圖3、圖4,本發明自行車用訓練器的較佳實施例 包含-支架3、一阻力裝置4、一感應組5及—驅動件6The bracket 11 is intended to be the bicycle (not shown) - the wheel 2 is remote from the ground, causing the wheel 2 to rotate in place during pedaling. The resistance device 12 has a wheel base 121 disposed on the bracket U, a resistance wheel 122 disposed between the wheel bases i2i and in contact with the bicycle wheel 2, and the wheel base m and the resistance wheel 122 are penetrated in an axial direction. An axle 123 is sleeved on the axle = 3 - a sensing member 124 passing through the segment and located on the side of the wheel housing 121, and is fixed on one side of the wheel i 121 and equidistantly distributed around the sensing member 124 The number of magnetic bodies 125 〇 _ because the bicycle wheel 2 is abutted against the resistance wheel 122, when the wheel 2 is rotated back, the resistance wheel 122 is driven to rotate, so that the sensing member coaxial with the resistance wheel m 124 Synchronous rotation, and in the process of rotation, affected by the magnetic force of the magnetic n 125, a blocking effect occurs, so the rider must exert a force to pedal, in order to make the wheel 2 rotate, thereby achieving the motion effect . However, the distance between the magnetic body 125 and the sensing member 124 may affect the magnitude of the magnetic resistance. Therefore, the magnetic resistance that can be generated when the magnetic body 125 and the sensing body are fixed at a distance of 124 ^ There is no change, however, 1273915 usually requires a large pedaling force to become less laborious due to inertia and centrifugal force. At this time, when the bicycle wheel 2 is initially started, with the speed of the wheel 2 The improvement, while overcoming some of the resistance, will make the pedaling effect also greatly reduced. SUMMARY OF THE INVENTION A bicycle trainer. A bicycle training device, an inductive group, and a driving member of the present invention.兮 “3 h a resistance – car noisy”. The bracket is a bracket, and the pair of bicycles are pivotally mounted on the bracket and can be coupled to the wheel base and the wheel base and the axis of the wheel One of the resistance wheels of the Tenghai is in the mountain. The first and second sets of the door have a first inductive member spaced apart from the wheel seat at a fixed distance along the axis, and rotate synchronously with the axle and are displaceable relative to the first sensing member along the axle. A second sensing member generates magnetic attraction between the first and second sensing members. The driving member pushes the second sensing member to reduce the distance from the first sensing member as the rotational speed of the axle increases. The effect of the invention is that as the speed of rotation increases, the retarding force is increased, so that the % occupant does achieve the exercise effect. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the detailed description of the preferred embodiment of FIG. 1273915 Referring to FIG. 3 and FIG. 4, a preferred embodiment of the bicycle training device of the present invention comprises a bracket 3, a resistance device 4, a sensing group 5 and a driving member 6.

A magnetic field is generated. In the embodiment, the third money piece 53 is made of a metal material, and has a pitch with the first sensing element 、, and: 14: 14 54 in the state of the bullet, which will drive the first The two sensing members 53 are displaced from the direction of the first sensing member 52. The driving member 6 has a 61 that is fixed to the wheel axle and is located between the wheel housing 41 and the second sensing member 53 and is displaceably inserted through the axle housing 41 and The second sensing member 53 is directed to the first slide bar 62 and the plurality of flying hammers 63. The shaft seat has a ring hole 611, 1273915 which is bored along the axis and is partially penetrated by the second sensing element 53. The ring hole 611 is formed in the shaft hole 611 and can block a ring protrusion of the second sensing element μ. Γ2, and two side holes 613 formed on one side of the surface and communicating with the shaft hole. The seek bar 62 has a latching head 621 on the shaft mount, respectively. Referring to FIG. 6 , the 7 ° Hai Fei fly bell 63 is respectively pivoted in the side hole 613 and has a push end 631 formed at one end and in contact with the second sensing member 53 and a one formed at the other end. Throw the end. *(4)® 3, Figure 4' When the bicycle wheel 7 is first rotated back, the resistance wheel 42 is moved together, the moxibustion M is turned back to c π 曰, and the figure 5 and FIG. 7 are made to be the same as the resistance wheel 42. The shaft seat 61 synchronously drives the second induction (four) movement through the sliding rods 62, and is affected by the magnetic force of the first induction member , during the rotation process, and the 乂 block effect, at this time, the rider It is necessary to apply a force to step on the wheel to rotate the self-driving wheel 7, thereby achieving a sporting effect. Referring to Fig. 7 and Fig. 8, as the rotational speed of the bicycle wheel 7 becomes faster, due to the inertia and centrifugal force, the flying bells 63 (four) are terminated 632 _. Withdrawing outwards 'At this time', the push end (3) of the flying bells 63 will relatively squeeze the second sensing member 53 so that the first sensing member 53 overcomes the elastic element scooping force " The rod 62 faces the first induction 4 along the axle 43 and the second sensing member 53 and the first sensing member are spaced from each other to the slider 62 (see /5) as a bolt 621 (see Figure 5) Abutting the shaft seat μ'When the force is larger, the smaller the distance D between the second sensing element 53 and the first induction: 52, the larger the magnetic resistance, and the smaller the centrifugal force: The larger the distance D between the second sensing member 53 and the first sensing member 52 is, the smaller the resistance is. 'By this, the resistance is automatically adjusted according to the rotational speed of the vehicle 357. 1273915 It is worth mentioning that 'the first The second sensing member 二 of the second sensing member 5 can also be a magnetic body, and the first money member 52 is made of a magnetically permeable metal material with the second sensing member 53. Thereby, the second sensing member 53 can also automatically adjust the distance from the first sensing member 52, resulting in different magnetic f attracting power, and having different size blocking effects. Referring to Figure 9, is the present invention The second preferred embodiment is substantially the same as the first preferred embodiment except that the wide first induction V2 is sleeved on the rotating shaft 43 and the adjacent two sensing members 53 and the The shaft base 61 is displaceably displaceable along the axis x direction of the rotating shaft 43 and extends away from the wheel base 431. The rotational speed of the crucible is fastened, and the speed of the crucible becomes faster, which is also due to the consistency and separation. The throwing end 632 of 63 is thrown outward with the centrifugal force, and the pressing end 63 is used to squeeze the displacement of the second component to reduce the displacement of the second sensing member, according to the rotational speed, Η), which is a third preferred embodiment of the present invention, the beryllium palladium examples are substantially the same, the difference being: "The second inductive member 53 has a first recess 531 formed adjacent to the axis and along the axis Lighter=two parts, the driving member 6 further has a plurality of rollers 64.
