Detailed ways

In order to make the above-mentioned purpose, features and advantages of the present invention more comprehensible, preferred embodiments are specifically cited below and described in detail in conjunction with the accompanying drawings.

Please refer to FIG. 2 , the motorcycle parking device 100 of this embodiment mainly includes a vehicle frame 110 , a control valve 120 , a brake master cylinder 130 , a brake caliper 140 and a side stand 150 .

The frame 110 may carry the body (not shown) and other related structures of a motorcycle.

As shown in Figure 2, Figure 3A and Figure 3B, the control valve 120 is connected to the vehicle frame 110, and the control valve 120 has a valve body 121, an oil inlet chamber 122, an oil outlet chamber 123, a plunger 124, an elastic Component 125 and an oil seal 126. The oil inlet chamber 122 and the oil outlet chamber 123 are formed in the valve body 121 , and brake oil (not shown) is contained in the oil inlet chamber 122 and the oil outlet chamber 123 . The oil inlet chamber 122 communicates with the oil outlet chamber 123 . The plunger 124 is disposed in the oil outlet chamber 123 in a movable manner, and the plunger 124 protrudes from the valve body 121 . The elastic element 125 is connected between an inner wall 123 a of the oil outlet chamber 123 and the plunger 124 . The oil seal 126 is sheathed on the plunger 124 , and the oil seal 126 abuts against the inner wall 123 a of the oil outlet chamber 123 . In addition, the oil seal 126 can also be replaced by a one-way cup.

The master brake cylinder 130 communicates with the oil inlet chamber 122 of the control valve 120 through an oil delivery pipe 160 .

The brake caliper 140 communicates with the oil outlet chamber 123 of the control valve 120 through an oil delivery pipe 170 . It should be noted that when the brake master cylinder 130 is in operation, it communicates with the brake caliper 140 through the oil inlet chamber 122 and the oil outlet chamber 123 (this part will be described later). In addition, the brake caliper 140 is disposed on a brake disc (not shown) of a wheel.

The side stand 150 is rotatably connected to the frame 110 , and the side stand 150 selectively pushes against the plunger 124 of the control valve 120 .

When the motorcycle parking device 100 is not in operation, the plunger 124 is located at the rightmost position in the oil outlet chamber 123 , as shown in FIG. 3A . At this time, the master brake cylinder 130 can communicate with the brake caliper 140 through the oil inlet chamber 122 and the oil outlet chamber 123 .

When the locomotive parking device 100 is operated, that is, when the locomotive configured with the locomotive parking device 100 is parked sideways, the side stand 150 can be rotated from the position shown in FIGS. 2 and 3A (downward) to The position shown in FIG. 3B is in contact with a ground. Here, the side stand 150 pushes against the plunger 124 of the control valve 120 , thus causing the plunger 124 to move (to the left) in the oil outlet chamber 123 and causing the elastic element 125 to be compressed. It should be noted that the oil seal 126 sleeved on the plunger 124 will also move accordingly, and thus pass through the connection between the oil inlet chamber 122 and the oil outlet chamber 123 . As mentioned above, after the oil seal 126 passes through the connection between the oil inlet chamber 122 and the oil outlet chamber 123, the brake master cylinder 130 cannot communicate with the brake caliper 140 through the oil inlet chamber 122 and the oil outlet chamber 123 (that is, the oil seal 126 will block the brake master cylinder 130 from communicating with the brake caliper 140), and the plunger 124 will press the brake oil in the oil outlet chamber 123 to the brake caliper 140, thereby forcing the brake caliper 140 to produce a braking effect on the brake disc of the wheel. Therefore, when the locomotive equipped with the locomotive parking device 100 is parked sideways, its wheels will not be able to rotate, even if the locomotive is parked sideways on a sloped road, so that the locomotive can be prevented from toppling over and being damaged by collisions. .

On the other hand, when the side stand 150 is rotated (upward) from the position shown in FIG. 3B to the position shown in FIGS. 2 and 3A , the side stand 150 will separate from the plunger 124 of the control valve 120 . Here, the plunger 124 can be moved to the rightmost position in the oil outlet chamber 123 by the restoring force provided by the elastic element 125 , so that the master brake cylinder 130 is communicated with the oil inlet chamber 122 and the oil outlet chamber 123 again. On the brake caliper 140 , the brake caliper 140 releases the brake disc of the wheel.
