Description of the Invention: TECHNICAL FIELD The present invention relates to a sports apparatus, and more particularly to a bicycle simulator. [Prior Art] Living in this fiercely competitive, time-critical 21st century, people often ignore the importance of physical health for work, let alone take time out for outdoor sports. As a result, many people place a bicycle simulator in their home and install the original bicycle, so they can simulate riding a bicycle at home without having to go outdoors. During the use of the bicycle simulator, the bicycle components generate heat by rubbing against each other. The longer the use time, the greater the heat generated between the bicycle simulator components, which tends to cause component damage. Therefore, having a good heat sink is an essential condition for a bicycle simulator.

According to an embodiment of the present invention, a bicycle simulator is provided, comprising a bracket, a hollow roller, a spindle, at least one support member, a fan, and a resistance generator. The bracket is used to position at least one of the driving wheels of a bicycle. The hollow roller is used to abut the driving wheel of the bicycle. The mandrel is located in the hollow roller and pivotally supports the bracket. The support member connects the mandrel to the hollow roller. 201103609 The fan is housed in the hollow roller. The resistance generator is connected to the mandrel. According to another embodiment of the present invention, a bicycle simulator is provided, comprising a bracket, a spindle, a fan, a hollow roller, at least one support member, and a resistance generator. The bracket is used to position at least one drive wheel of a bicycle. The mandrel pivotally supports the bracket. The fan is connected to the mandrel.

The user can use the bracket 100 to suspend a bicycle rear drive wheel 15 and the rear drive wheel 150 against the column hollow roller 11 〇. The hollow roller 110 is connected to the mandrel 120 and the fan 130, and the central axis 120 is connected to the hollow roller 110 through the support member 121. The two ends of the mandrel 120 are respectively connected to the bracket 100 and the resistance generator 140, and the fan 130 is connected to the fan 130. The mandrel is 12 〇. When the user drives the wheel 150 after driving the bicycle, the hollow roller 11 turns with the rotation, and drives the spindle 120, the fan 130, and the resistance generator 140 to rotate. Therefore, the fan 13 位于 located in the hollow roller U 会 will drive the surrounding air convection due to the rotation, thereby achieving the effect of heat dissipation. The bracket 100 includes a set of clips 1〇1 that can be clamped to a bicycle rear drive wheel 150' for positioning the rear drive wheel 15 of the bicycle.

心 心車^20為一圓柱體，其位於中空滚輪11〇内，且· ^ 120的兩端突出於中空滾輪11〇並樞接於支架刚。心 軸U0與中空滾輪110間透過支撐件⑵連接。支樓件⑶ 之-端固接於心軸120的側邊’另一端則固接於中空滾輪 no的内侧。支撐件121可將心軸120固定於中空滚輪110 的軸心位置，使中空滾輪11G受自行車之後㈣輪15〇驅 動時’心軸120可同時受中空滾輪11()同軸連動。 風扇130容設於中空滾輪11〇中，並連接於心軸12〇。 風扇130位於中空滾輪110之一端口處。當心軸12〇受中 空滾輪110同軸連動時，風扇130會隨著心軸12〇轉動， 並帶動周圍的空氣並導通至中空滾輪110的另一端。 阻力產生器140與心軸120之一端連接，且就鄰於風 扇130。當使用者驅動自行車之後驅動輪150而帶動中空 滾輪110轉動時，心軸120會隨著中空滾輪11〇連動且帶 動阻力產生器140產生一阻力，此阻力會提升後驅動輪150 帶動中空滚輪110的難度。 無論是心軸120與中空滚輪110連動的過轾，或是心 201103609 軸1則轴連動阻力產生器14G時^件間都會產生熱能， *增加元件耗損的機率。因此在中空滚輪11G與心轴120 轉動的同時，透過風扇130加速熱空氣的對流’達巧散熱 的效果。且將風扇130容設於中空滚輪U〇中，可提升風 扇130運作時的安全性，而不需另外增設風扇130的安全 遮蔽裝置’降低生產的成本。 請參照第2圖，係繪示依照第1圖之心轴120及風扇 130的立體示意圖。 • 風扇130包含複數個扇# I31，其一端連接於心轴120 之侧邊。配合第i圖可知，當心軸120隨著中空滚輪110 轉動時，扇t m亦隨著心#⑽而轉動。由於扇葉131 毗鄰於阻力產生器140，因此在扇葉131轉動的同時，促 進了周圍的空氣對流，而導開隊力產生器140所產生的熱 量’達到散熱的功效。 請參照第3 ®，係綠示#照本發明另一實施方式之自 行車模擬器的中空滾輪110内部立體不意圖。 Φ 中空滾輪110圍繞一心軸120及一風扇3〇〇。特別的 是’風扇300包含複數個扇蘩301 ’且各個扇葉301連接 於中空滾輪11〇的内侧。當中空滾輪u〇轉動時’各個扇 葉301可帶動周圍空氣流動，達到散熱的效果。 請參照第4圖，係繪示依照本發明又一實施方式之自 行車模擬器的部分結構立體分解圖。 中空滚輪110圍繞一心軸400及複數個支撐件4〇1， 其心軸400是一中空管，而各個支撐件4〇1的兩端分別連 201103609 接於心軸400的外側及中空滚輪u〇的内側，使心軸4〇〇 固定於中空滾輪110内。心軸400更包含一軸件41〇，其 為一可拆換式的圓柱體，並穿設於心轴4〇〇 _，且一端樞 接於支架100，另一端則連接於阻力產生器14〇，使支架 100及阻力產生器140透過轴件410與心軸400連接。風 ^ 420包含一葉輪421及複數個扇葉422。葉輪421為一 環狀體並可套設於軸件410上，而各個扇葉422分別連接 在葉輪421的邊緣。風扇420與軸件41〇安裝於中空滾輪 • U0中，並可隨著中空滚輪110同軸轉動。 5月參照第5圖，係繪示依照剖線5_5之剖示平面圖。 田弟5圖可知，中空滾輪11〇之一端口具有一預留空 間5⑻’其用以容設風扇420。因此，當風扇42〇容設於中 空=m中時，可隨著中空浪輪的作動在預留空間 中轉動’以帶動周圍的空氣流動，達到散熱的效果。The heart car ^20 is a cylinder, which is located in the hollow roller 11〇, and both ends of the ^ 120 protrude from the hollow roller 11〇 and are pivotally connected to the bracket. The mandrel U0 is connected to the hollow roller 110 through a support member (2). The end of the branch member (3) is fixed to the side of the mandrel 120, and the other end is fixed to the inside of the hollow roller no. The support member 121 can fix the mandrel 120 to the axial center position of the hollow roller 110, so that when the hollow roller 11G is driven by the bicycle (four) wheel 15 ’, the mandrel 120 can be coaxially coupled by the hollow roller 11 () at the same time. The fan 130 is accommodated in the hollow roller 11 , and connected to the mandrel 12 〇. Fan 130 is located at one of the ports of hollow roller 110. When the mandrel 12 is coaxially coupled by the idler roller 110, the fan 130 rotates with the mandrel 12 and drives the surrounding air and conducts to the other end of the hollow roller 110. The resistance generator 140 is coupled to one end of the mandrel 120 and is adjacent to the fan 130. When the user drives the bicycle to drive the wheel 150 to drive the hollow roller 110 to rotate, the mandrel 120 will interlock with the hollow roller 11 且 and drive the resistance generator 140 to generate a resistance, which will increase the driving wheel 150 to drive the hollow roller 110. Difficulty. Regardless of whether the mandrel 120 is interlocked with the hollow roller 110, or the heart of the 201103609 axis 1 axis, the resistance generator 14G generates heat between the components, and increases the probability of component wear. Therefore, while the hollow roller 11G and the spindle 120 rotate, the fan 130 accelerates the convection of the hot air to achieve a heat dissipation effect. Moreover, the fan 130 is accommodated in the hollow roller U〇, which can improve the safety of the operation of the fan 130 without the need to additionally add a safety shielding device of the fan 130 to reduce the production cost. Referring to Fig. 2, a perspective view of the mandrel 120 and the fan 130 according to Fig. 1 is shown. • The fan 130 includes a plurality of fans #I31, one end of which is coupled to the side of the mandrel 120. As can be seen from the figure i, when the mandrel 120 rotates with the hollow roller 110, the fan tm also rotates with the heart #(10). Since the blade 131 is adjacent to the resistance generator 140, while the blade 131 rotates, the surrounding air convection is promoted, and the heat generated by the ball force generator 140 is released to achieve the heat dissipation effect. Please refer to the third ®, which is a stereoscopic view of the hollow roller 110 of the bicycle simulator according to another embodiment of the present invention. Φ The hollow roller 110 surrounds a mandrel 120 and a fan 3〇〇. Specifically, the fan 300 includes a plurality of fan blades 301' and each of the blades 301 is coupled to the inner side of the hollow roller 11b. When the hollow roller u〇 rotates, each of the blades 301 can drive the surrounding air to flow to achieve the heat dissipation effect. Referring to Figure 4, there is shown a perspective exploded view of a portion of a bicycle simulator according to still another embodiment of the present invention. The hollow roller 110 surrounds a mandrel 400 and a plurality of supporting members 4〇1, wherein the mandrel 400 is a hollow tube, and the two ends of each supporting member 4〇1 are respectively connected to the outer side of the mandrel 400 and the hollow roller u. The inner side of the crucible fixes the mandrel 4〇〇 in the hollow roller 110. The mandrel 400 further includes a shaft member 41〇, which is a detachable cylinder and is disposed on the mandrel 4〇〇_, and one end is pivotally connected to the bracket 100, and the other end is connected to the resistance generator 14〇. The bracket 100 and the resistance generator 140 are coupled to the mandrel 400 through the shaft member 410. The wind ^ 420 includes an impeller 421 and a plurality of blades 422. The impeller 421 is an annular body and can be sleeved on the shaft member 410, and each of the blades 422 is connected to the edge of the impeller 421. The fan 420 and the shaft member 41 are mounted in the hollow roller • U0 and are rotatable coaxially with the hollow roller 110. Referring to Fig. 5 in May, a plan view in accordance with section line 5_5 is shown. As shown in Figure 5, one of the ports of the hollow roller 11 has a reserved space 5 (8)' for housing the fan 420. Therefore, when the fan 42 is disposed in the medium=m, it can rotate in the reserved space with the operation of the hollow wave wheel to drive the surrounding air to flow, thereby achieving the effect of heat dissipation.
