Please refer to FIG. 3 and FIG. 4 , the operation part 40 includes a connected button part 41 and a second wheel transmission part 43 , the second wheel traction part 33 is connected with the second wheel transmission part 43 , and the button part 41 is driven by an external force to drive the second wheel transmission part 43 . The wheel transmission part 43 moves, so that the second wheel traction part 33 drives the second wheel locking part 32 . Specifically, the second wheel traction portion 33 includes a second wheel first traction member 331 and a second wheel second traction member 333 , and the second wheel locking portion 32 includes a second wheel left locking member 321 and a second wheel right locking member 323 , the second wheel 30 includes a second left wheel 301 and a second right wheel 303 (as shown in FIG. 1 ), one end of the first traction member 331 of the second wheel is connected to the left locking member 321 of the second wheel, and the first traction member of the second wheel The other end of the second wheel 331 is connected to one side of the transmission part 43 of the second wheel; On the other side of the transmission part 43 , the button part 41 is driven by an external force to drive the second wheel transmission part 43 to move, and the second wheel left locking part 321 is driven by the second wheel first traction member 331 to release the lock; The second wheel traction member 333 drives the second wheel right locking member 323 to release the lock, so that both the left second wheel 301 and the right second wheel 303 can rotate relative to the frame 10 . Further, the button portion 41 is provided with an extension portion 42 that is slidably inserted into the vehicle frame 10 , the extension portion 42 is provided with an insertion hole 44 , the second wheel transmission portion 43 is a disc structure pivotally connected to the vehicle frame 10 , and the second wheel transmission portion 43 A first connecting hole 431 for connecting the first traction member 331 of the second wheel, a second connecting hole 433 for connecting the second pulling member 333 of the second wheel, and a lug portion 45 extending into the insertion hole 44 are provided. It can be understood that the second wheel transmission part 43 is driven to rotate by a certain angle by pressing the button part 41 , thereby prompting the second wheel first traction member 331 and the second wheel second traction member 333 to pull the second wheel left locking member 321 respectively. The left second wheel 301 is released and the second wheel right locking member 323 is released for the right second wheel 303 . Furthermore, the first connection hole 431 and the second connection hole 433 are symmetrically arranged on the same diameter. The first connection hole 431 is connected to the second connection
The holes 433 are spaced at a certain distance, and the specific lengths are set according to actual needs, which is not limited herein. When an external force is applied to the button part 41, the extension part 42 drives the second wheel transmission part 43 to rotate, so that the second wheel first traction member 331 and the second wheel second traction member 333 move a certain distance (refer to FIG. 3 and FIG. 4 ). can be seen in combination), thereby respectively driving the second wheel left locking member 321 from the second wheel positioning groove 351 to release the lock and driving the second wheel right locking member 323 to separate from the second wheel positioning groove 351 to release the lock, thereby realizing the left second wheel 301 Both the right second wheel 303 and the second wheel 303 can be rotated relative to the vehicle frame 10 , so that both the first wheel 20 and the second wheel 30 can be rotated relative to the vehicle frame 10 . That is to say, the above-mentioned operating portion 40 uses a pressing method to realize the unlocking of the second-wheel locking portion 32 , which can be referred to as a pressing operating member. Of course, the operating part 40 can also be configured as a sliding operating part, a rotary operating part or a boat-shaped lever operating part in addition to the pressing operating part.
舉例而言，當操作部40為滑移操作件時，滑移操作件於車架10的對應位置設置有滑動槽，提供滑移操作件所需的滑移操作距離，藉此，滑移操作件可在受到外力推動時直接對第二輪牽引部33進行拉提，進而帶動第二輪鎖定部32進行釋鎖；或者，滑移操作件亦可與第二輪傳動部43搭配使用，透過連動機構使第二輪傳動部43受滑移操作件的帶動而帶動第二輪第一牽引件331和第二輪第二牽引件333位移，同樣達到帶動第二輪左鎖定件321和第二輪右鎖定件323釋鎖的目的，但此僅為一示範之實施舉例，於此不對滑移操作件之組件設置方式進行限定。又當操作部40舉例為轉盤操作件時，其可直接設置穿孔供至少一個第二輪牽引部33穿設連接於上，且轉盤的部分外露於車架10的對應設置位供使用者進行操作，當轉盤操作件受到外力轉動時，將直接對第二輪牽引部33進行拉提，進而帶動第二輪鎖定部32進行釋鎖；或者，轉盤操作件可設置有鎖定部及復位單元，並搭配一組鎖定件和釋鎖件進行使用，當轉盤操作件轉動到可帶動第二輪鎖定部32達到釋鎖目的的釋鎖角度時，鎖定件將與轉盤操
作件上的鎖定部相卡合，此時第二輪鎖定部32常駐於鎖定解除位置，第二輪30可短暫時間的持續性相對車架10能進行轉動，且操作者無須持續性的對轉盤操作件施加外力，而當與鎖定件搭配的釋鎖件對鎖定件進行釋鎖時，則轉盤操作件受復位單元的作用力復位至一般位置，不在對第二輪牽引部33進行拉提，第二輪鎖定部32從而回復至鎖定位置，但此僅為一示範之實施舉例，於此不對滑移操作件之組件設置方式進行限定。
For example, when the operating portion 40 is a sliding operating member, the sliding operating member is provided with a sliding groove at a corresponding position of the vehicle frame 10 to provide a sliding operating distance required for the sliding operating member, whereby the sliding operating member When pushed by an external force, the sliding element can directly pull the second-wheel traction part 33, thereby driving the second-wheel locking part 32 to release; The linkage mechanism enables the second wheel transmission portion 43 to be driven by the sliding operating member to drive the second wheel first traction member 331 and the second wheel second traction member 333 to displace, and also drives the second wheel left locking member 321 and the second wheel. The purpose of unlocking the right wheel locking member 323 is, but this is only an exemplary implementation example, and the assembly arrangement of the sliding operating member is not limited herein.

The locking parts on the work piece are engaged, and the second wheel locking part 32 is always in the unlocking position, and the second wheel 30 can rotate relative to the frame 10 for a short period of time continuously, and the operator does not need to continuously adjust it. The turntable operating member exerts an external force, and when the unlocking member matched with the locking member releases the locking member, the turntable operating member is reset to the normal position by the force of the reset unit, and does not pull the second-wheel traction part 33. , the second wheel locking portion 32 thus returns to the locking position, but this is only an exemplary implementation example, and the assembly arrangement of the sliding operating member is not limited herein.
又舉例而言，當操作部40為船型槓桿操作件時，其是利用船型槓桿操作件受到外力施壓時進行槓桿運動，進而改變連接於船型槓桿操作件的第二輪牽引部33的行程，達到帶動第二輪鎖定部32進行釋鎖的目的，其設置原理與方式與前述之其他類型操作件相同，於此不再贅述。
For another example, when the operating portion 40 is a boat-shaped lever operating member, it uses the boat-shaped lever operating member to perform lever motion when it is pressed by an external force, thereby changing the stroke of the second-wheel traction portion 33 connected to the boat-shaped lever operating member, To achieve the purpose of driving the second-wheel locking portion 32 to release the lock, the principle and manner of its setting are the same as those of the other types of operating elements described above, and will not be repeated here.

33的運動距離不足以使其由鎖定解除位置轉變為鎖定位置，因而，第二輪鎖定部32依然位於鎖定解除位置，從而實現第一輪20和第二輪30均相對車架10能進行360度旋轉。
More specifically, the driving member 51 is pivotally connected to the frame 10 and is provided with a first through hole 513 and a second through hole 515 at a certain distance (please refer to FIG. 11 ). The second-wheel traction part 33 is connected to the second through hole 515 . When the driver 13 is in the backward position, the first through hole 513 and the second through hole 515 are located at the first position, the operating part 40 drives the driving pin 53 to move by operating the traction part 55 , and the driving pin 53 drives the driving member 51 to rotate to make the first through hole 513 and the second through hole 515 are located in the second position, the traction part of the first wheel and the traction part 33 of the second wheel move a certain distance, and the traction part 33 of the second wheel pulls the locking part 32 of the second wheel away from the positioning groove 351 of the second wheel to release the lock , and the moving distance of the traction part of the first wheel is not enough to make it change from the unlocked position to the locked position, therefore, the locking part 22 of the first wheel is still in the unlocked position, so that the first wheel 20 and the second wheel 30 are opposite to each other. The frame 10 can rotate 360 degrees; when the driver 13 is in the forward position, the first through hole 513 and the second through hole 515 are located in the third position because the driver 51 is driven to rotate during the reversing process of the driver 13, and the operation part 40 uses the The driving pin 53 is driven by the operating traction part 55, and the driving pin 53 drives the driving member 51 to rotate so that the first through hole 513 and the second through hole 515 are located in the fourth position. 51 rotates to move a certain distance, the traction part of the first wheel pulls the locking part 22 of the first wheel to release the rotation part 21 of the first wheel, and the traction part of the second wheel pulls the locking part 22 of the first wheel

When the rider 13 is in the rearward position, the second wheel 30 is on the same side as the rider 13 . Since the second wheel locking portion 32 defines the second wheel rotation portion 31 , the rotation of the second wheel 30 relative to the frame 10 is restricted. . The first wheel locking portion 22 releases the second wheel rotating portion 31 , so that the first wheel 20 can rotate relative to the frame 10 . At this time, the operating part 40 is subjected to external pressure, and uses the operating pulling part 55 to drive the driving pin 53 to move, and the operating pulling part 55 brings the driving pin 53 to move along the inclined groove, thereby driving the driving member 51 to rotate at a certain angle, and the driving member 51 will drive the first The pulling part 33 of the second wheel pulls upward, and the pulling part 33 of the second wheel drives the locking part 32 of the second wheel to release the lock, so that the second wheel 30 can rotate 360 degrees.

下面詳細闡述本實施例中車手13換向的過程中如何實現第一輪20和第二輪30均相對車架10能進行360度旋轉。
The following describes in detail how the first wheel 20 and the second wheel 30 can both rotate 360 degrees relative to the frame 10 during the reversing process of the driver 13 in this embodiment.
車手13由後向位置向前向位置轉換，即第一輪20與車手13處於同一側，帶動轉動本體11由第一轉動位置轉向第二轉動位置，藉助第一拉動件93的作用，收緊第二輪鎖定部32到第二輪定位槽351的距離，使得第二輪鎖定部32釋鎖第二輪轉動部31，因而，第二輪30相對車架10能進行轉動；同時釋放第一輪鎖定部22到第一輪定位槽的距離，在第一輪復位件23的作用下，使得第一輪鎖定部22鎖定第一輪轉動部21，限制第一輪20相對於車架10轉動。此時，操作部40受外界壓力，拉緊第三拉動件957，藉由連接體98和旋轉體99的作用，帶動第四拉動件959拉緊，第四拉動件959直接或間接帶動第一輪鎖定部22釋鎖第一輪轉動部21，比如通過連接二端953拉動第一連接件96移動或通過連接二端953拉動第一拉動件93的第一端931以帶動第一連接件96移動，以收緊第

The driver 13 is switched from the backward position to the forward position, that is, the first wheel 20 and the driver 13 are on the same side, and the rotating body 11 is driven from the first rotating position to the second rotating position. The distance from the second wheel locking portion 32 to the second wheel positioning groove 351 enables the second wheel locking portion 32 to release the second wheel rotating portion 31, so that the second wheel 30 can rotate relative to the frame 10; The distance from the wheel locking portion 22 to the first wheel positioning groove, under the action of the first wheel reset member 23, makes the first wheel locking portion 22 lock the first wheel rotating portion 21, and restricts the first wheel 20 from rotating relative to the frame 10 .

The driver 13 is switched from the forward position to the rear position, that is, the second wheel 30 is on the same side as the driver 13, which drives the rotating body 11 from the second rotating position to the first rotating position. The distance between the first wheel locking portion 22 and the first wheel positioning groove enables the first wheel locking portion 22 to release the first wheel rotating portion 21, so that the first wheel 20 can rotate relative to the frame 10; at the same time, the second wheel locking portion is released The distance from the part 32 to the second wheel positioning groove 351 , under the action of the second wheel reset member 34 , the second wheel locking part 32 locks the second wheel rotating part 31 , and restricts the second wheel 30 from rotating relative to the frame 10 . At this time, the operation part 40 is subjected to external pressure to tighten the third pulling member 957, and through the action of the connecting body 98 and the rotating body 99, the fourth pulling member 959 is driven to tighten, and the fourth pulling member 959 directly or indirectly drives the second pulling member 959. The wheel locking portion 32 releases the second wheel rotating portion 31 , for example, by connecting the three ends 955 to pull the second connecting member 97 to move or pulling the second end 933 of the first pulling member 93 by connecting the three ends 955 to drive the second connecting member 97 move to tighten the distance between the second wheel locking portion 32 and the second wheel positioning groove 351 , so that the second wheel locking portion 32 releases the second wheel rotating portion 31 , so that the second wheel 30 can be moved relative to the frame 10 turn. Therefore, both the first wheel 20 and the second wheel 30 can be rotated relative to the frame 10 .
