當該載具本體1被推動，使得該輪體33於一地面上滾動行走時，該輪框32也會被帶動而隨之繞著該輪軸31轉動，同時會連動該等第一行星齒輪52一起繞著該輪軸31公轉，並嚙接帶動該第一太陽齒輪53連同該齒輪盤51轉動，而位於該齒輪盤51上的該等第二行星齒輪54也會一起繞著該輪軸31公轉，進而嚙接帶動該第二太陽齒輪55連同該鼓剎盤42轉動，由於上述兩組太陽行星齒輪組的齒數比，是經過使用需求而計算出合適的齒數比，故可藉以進一步增速驅動該鼓剎盤42轉動。When the vehicle body 1 is pushed so that the wheel body 33 rolls on a ground, the wheel frame 32 will also be driven to rotate around the wheel shaft 31, and at the same time, the first planetary gears 52 will be linked. Revolve together around the axle 31, and engage to drive the first sun gear 53 together with the gear plate 51, and the second planetary gears 54 located on the gear disc 51 will also revolve around the axle 31, Furthermore, the second sun gear 55 is engaged to drive the second sun gear 55 together with the drum brake disc 42. Since the gear ratio of the two sets of the above-mentioned sun planetary gear sets is calculated through use requirements, a suitable gear ratio can be calculated, so that the gear can be driven at a higher speed. The drum brake disk 42 rotates.
當該輪體33以正常且穩定的速度滾轉時，該鼓剎盤42被帶動而處於低速狀態下，此時由於轉動產生的離心力並不足讓該等剎車片43向外甩開，所以該等剎車片43仍會縮入藏置在該鼓剎盤42內，並與該剎車鼓41相間隔，不會接觸摩擦該剎車環412產生剎車阻力，因此該傳動單元5、該輪框32及該輪體33會以正常的轉速滾轉，使用者能受到良好的輔助行走作用。When the wheel body 33 rolls at a normal and stable speed, the drum brake disc 42 is driven to be in a low speed state. At this time, the centrifugal force generated by the rotation is not enough to cause the brake pads 43 to swing outward, so After the brake pads 43 are still retracted and hidden in the drum brake disc 42 and spaced from the brake drum 41, they will not come into contact with the brake ring 412 to generate braking resistance. Therefore, the transmission unit 5, the wheel frame 32, and The wheel body 33 will roll at a normal rotation speed, and the user can receive a good auxiliary walking effect.
而當該輪體33因異常狀況而快速滾轉時，該鼓剎盤42也會被帶動快轉至高於正常轉速，此時該等剎車片43即會離心甩擺伸出該鼓剎盤42外，並會滑動接觸摩擦該剎車環412，產生相對應的剎車阻力，以減緩該鼓剎盤42的轉速，相對使得該傳動單元5、該輪框32及該輪體33的轉速變慢甚至剎止，進而達到自動剎車效果，可解決快速突衝的問題，提供使用者更好的安全保護措施。When the wheel body 33 rolls quickly due to abnormal conditions, the drum brake disc 42 will also be driven to rotate faster than normal. At this time, the brake pads 43 will spin out and extend out of the drum brake disc 42. In addition, the brake ring 412 will be brought into sliding contact with the brake ring to generate corresponding braking resistance to slow down the rotation speed of the drum brake disc 42, which will relatively slow down the rotation speed of the transmission unit 5, the wheel frame 32, and the wheel body 33. The brake stops, and then achieves the effect of automatic braking, which can solve the problem of rapid burst and provide users with better safety protection measures.
更重要的是，本新型該轉輪裝置2除了具有上述鼓剎式剎車功能以外，還另外具有磁剎式剎車功能，也就是藉由該抑速單元6的設置，該磁剎盤61上的該等磁性件62也會在該磁剎盤61與該鼓剎盤42之間形成磁場，並會對該鼓剎盤42產生磁力，用以抑制減緩該鼓剎盤42轉速，值得一提的是，該磁剎盤61與該鼓剎盤42之間的距離還可以任由使用者定點控制，藉以調整磁阻力大小，產生不同的剎車效果。More importantly, in addition to the drum brake function described above, the wheel device 2 of the new type also has a magnetic brake function, that is, by the provision of the speed reduction unit 6, the magnetic brake disc 61 The magnetic pieces 62 also form a magnetic field between the magnetic brake disc 61 and the drum brake disc 42 and generate magnetic force on the drum brake disc 42 to suppress and slow down the rotation speed of the drum brake disc 42. It is worth mentioning that Yes, the distance between the magnetic brake disc 61 and the drum brake disc 42 can also be controlled by the user at a fixed point, so as to adjust the magnetic resistance to produce different braking effects.
如圖2所示，當該轉輪裝置2需要調整成阻力較小且轉速較快的狀態，以供病況較輕的使用者使用時，只要操控拉緊該鋼索63，使該磁剎盤61相對於該剎車鼓41，移至一個遠離該鼓剎盤42且壓縮該等彈簧64的弱煞位置，此時該等磁性件62對該鼓剎盤42產生的磁阻力變小，可減弱剎車效果，相對使得該移動載具在移動上較為自如，行動速度正常。As shown in FIG. 2, when the runner device 2 needs to be adjusted to a state of low resistance and high speed for use by a user with a light condition, as long as the steel cable 63 is tightened by manipulation, the magnetic brake disc 61 Relative to the brake drum 41, move to a weak braking position away from the drum brake disc 42 and compress the springs 64. At this time, the magnetic resistance generated by the magnetic members 62 to the drum brake disc 42 becomes smaller and can be weakened. The braking effect makes the mobile vehicle relatively free to move and the speed of movement is normal.
如圖3所示，而當該轉輪裝置2需要調整成阻力較大且轉速較慢的狀態，以供病況較重的使用者使用時，只要操控鬆放該鋼索63，並藉由該等彈簧64的復位彈力，使該磁剎盤61相對於該剎車鼓41，移至一個鄰近該鼓剎盤42的強煞位置，此時該等磁性件62對該鼓剎盤42產生的磁阻力變大，可增強剎車效果，相對使得該移動載具的移動受到較大的阻滯，行動速度緩慢。As shown in FIG. 3, when the runner device 2 needs to be adjusted to a state of greater resistance and slower speed for use by the heavier user, as long as the steel cable 63 is loosened and controlled, The reset elastic force of the spring 64 moves the magnetic brake disc 61 relative to the brake drum 41 to a strong braking position adjacent to the drum brake disc 42. At this time, the magnetic resistance generated by the magnetic members 62 to the drum brake disc 42 The larger the force, the stronger the braking effect. Relatively, the movement of the moving vehicle is greatly blocked, and the movement speed is slow.
綜上所述，本發明移動載具之轉輪裝置2，藉由該剎車單元4及該傳動單元5的設計，可經由該轉輪單元3的轉速快慢，來自動產生離心剎車效果，用以減緩或剎止該轉輪單元3的轉速，讓該載具本體1不會發生驟然加速的突衝意外，乃具有可提升安全性的功效，特別是該轉輪裝置2還藉由該抑速單元6的設計，不但可再增加磁力剎車效果，且其還能調整磁阻力，以改變剎車阻力大小，具有更加優良的剎車功效，適用於供各種身體狀況不同的使用者使用，故確實能達成本發明之目的。In summary, the wheel device 2 of the mobile vehicle of the present invention can automatically generate a centrifugal braking effect through the speed of the wheel unit 3 through the design of the brake unit 4 and the transmission unit 5 for Slowing down or stopping the rotation speed of the runner unit 3 so that the vehicle body 1 does not experience sudden acceleration acceleration, which has the effect of improving safety, especially the runner device 2 also uses the speed suppression The design of the unit 6 can not only increase the magnetic braking effect, but also adjust the magnetic resistance to change the braking resistance. It has more excellent braking effect and is suitable for users with different physical conditions. To achieve the purpose of the invention.
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
