In addition, the brake locking lever 3 is pivoted on the first brake operating device 4 .

Please refer to Figures 4 to 6 together. The first brake operating device 4 includes a first fixed frame 41, a balance member 43 and a first brake lever 42. The first fixed frame 41 is provided on a handle 10 or a vehicle frame. The balance member 43 is pivotally connected to the first fixed frame 41 with a second pivot point 412 and is provided with a second positioning portion 431. The first brake lever 42 is pivotally connected with the balance member 43 with a first pivot point 411. A first positioning part 421 is provided on the first brake wire 81. The first brake wire 81 includes a first inner wire 811 and a first sleeve 812 partially covering the first inner wire 811. One end of the first inner wire 811 is connected to the first positioning part 421, and the other end is connected to the first positioning part 421.

The brake lock lever 3 is provided with an interference portion 31, and an elastic member 45 is provided between the brake lock lever 3 and the first fixed frame 41. The brake locking lever 3 can be forced to one side, so that the interference portion 31 can selectively contact and interfere with the first blocking position 422, brake the first braking generating device 6 and the second braking generating device 7 to generate braking to achieve the parking effect, or contact By interfering with the second blocking position 423, the first braking generating device 6 is braked to generate braking to achieve a parking effect. In this embodiment, the first internal line 811 is between the first blocking position 422 and the second blocking position 423 .

Please refer to FIGS. 7 and 8 , which are respectively a side view of the first brake operating device and the brake lock lever in a first state and a partial cross-sectional view of FIG. 7 . As shown in the figure, when the rider operates the first brake lever 42, the first brake lever 42 will use the first pivot point 411 as a fulcrum to pull the first inner wire 811 of the first brake wire 81 through the first positioning portion 421. , the first inner wire 811 actuates the drum brake structure 61 of the first brake generating device 6 to generate braking force. When the first brake lever 42 takes the first pivot point 411 as the fulcrum, it will bear the resultant force of the first brake lever 42 pulling the first inner wire 811, and the resultant force will push the balance member 43 to rotate, causing the balance member 43 to move against the second brake wire 82. The second inner line 821 exerts force to allow the independent braking system 2 to also brake the vehicle. While the rider continues to operate the first brake lever 42, the rider also operates the brake lock lever 3, so that the interference portion 31 of the brake lock lever 3 contacts and interferes with the first blocking position 422 of the first brake lever 42, forming the following formation: In the first state shown in the figure, at this time, the rider no longer exerts force on the first brake lever 42, and the first blocking position 422 where the first brake lever 42 contacts and interferes with the brake lock lever 3 will become a fulcrum, and the first brake The drum brake structure 61 of the generating device 6 has not yet been released, and the rebound spring 62 continues to exert force on the first inner wire 811 of the first brake wire 81, so that the first brake lever 42 continues to move toward the balance member at the first pivot point 411. 43 exerts force to keep the balance member 43 exerting force on the second inner wire 821 of the second brake wire 82, so that the independent braking system 2 is still maintained in the braking state. At this time, both the first braking device 6 and the second braking device 7 can maintain the braking state of the vehicle when the rider no longer exerts force on the first braking lever 42, even if the rider uses the main stand. Park the vehicle so that the rear wheels are in the air, and the front wheels can still maintain braking, which can increase the stability of the vehicle when parking.

Please refer to Figures 9 and 10, which are respectively a side view and a partial cross-sectional view of Figure 9 when the independent braking system fails in the first state of a preferred embodiment of the present invention. As shown in the figure, when the first blocking position 422 of the first brake operating device 4 and the interference portion 31 of the brake lock lever 3 are in the first state of contact interference, and an abnormality occurs in the independent braking system 2 during the parking process, the independent braking system When the system 2 loses its braking function, the balance member 43 will empty the second inner wire 821 of the second braking wire 82 so that the first braking lever 42 contacts the first fixed frame 41 and is supported at an interference point 424 . Thereby, the first inner wire 811 of the first brake wire 81 remains in the pulled state, and does not release the brake on the drum brake structure 61 of the first brake generating device 6, and remains in the parking state.

Please refer to FIGS. 11 and 12 , which are respectively a side view of the first brake operating device and the second state of the brake lock lever and a partial cross-sectional view of FIG. 11 . As shown in the figure, when the rider operates the first brake lever 42 to cause the first brake generating device 6 and the second brake generating device 7 to brake the vehicle, the rider operates the brake lock lever 3 to cause the interference portion 31 of the brake lock lever 3 to engage with the vehicle. The second locking position 423 of the first brake lever 42 contacts and interferes to form the second state as shown in the figure.

Please refer to FIGS. 13 and 14 together, which are respectively a side view and a partial cross-sectional view of FIG. 13 when the first brake lever is released in the second state of a preferred embodiment of the present invention. As shown in the figure, when the rider no longer exerts force on the first brake lever 42, the second blocking position 423 where the first brake lever 42 contacts and interferes with the brake lock lever 3 will become a fulcrum. At this time, the first brake generating device 6 The drum brake structure 61 has not been released yet, and the rebound spring 62 continues to exert force on the first inner wire 811 of the first brake wire 81, so that the first brake lever 42 continues to move in the opposite direction to the balance member 43 at the first pivot point 411. Apply force so that the balance member 43 no longer exerts force on the second inner wire 821 of the second brake wire 82. At this time, the independent braking system 2 will release the braking force, that is, between the first brake operating device 4 and the brake lock lever 3 In the second parking state, only the first braking generating device 6 has braking action.
