When the brake handle (20) is released to a release position, the piston (15) can be subjected to the restoring preload of the elastic member (16) to push the push rod (17) to actuate the brake handle (20) to return to its original position, so that the hydraulic oil enters the piston chamber (100) again, thereby completing the action of releasing the brake. The feature of the present invention is that a locking assembly (30) is provided on the oil pump base (10) to temporarily prevent the brake handle (20) from returning to its original position after braking by limiting the push rod spindle (25), so as to provide a parking effect after braking.

The detailed structure of the locking assembly (30) is shown in the second, third and fourth figures. A through hole (18) is formed on the oil pump base (10) at the position of the push rod spindle (25) of the brake handle (20) corresponding to the brake position of the brake handle (20), and the opposite end axis of the push rod spindle (25) has a locking hole (26).

The present invention mainly implements the four sets of spiral gear teeth (32). In the embodiment, the screw gears (32) respectively have an action guide groove (320), a high position locking guide rail (321) and a release guide rail (322) connected to each other, wherein the release guide rail (322) is connected to the action guide groove (320), and the floating key (33) is inserted into the mounting hole (311) of the fixing seat (31), and the outer periphery of the floating key (33) has at least two sets of sliders corresponding to the aforementioned action guide groove (320). (330), the present invention mainly implements a slider (330) having four sets of action guide grooves (320) corresponding to the screw gear (32), and when the floating key (33) moves upward, the slider (330) will not separate from the action guide groove (320), and the top surface of the floating key (33) has guide cone teeth (331) twice the number of the screw gear (32), and the floating key (33) has a receiving groove (335) opening upward;

The limit gear (35) is disposed above the floating key (33), and the limit gear (35) has at least two sets of guide blocks (351) corresponding to the action guide grooves (320) of the spiral gear (32) on its periphery. The present invention mainly implements a method of providing four sets of guide blocks (351) corresponding to the action guide grooves (320), and the end surfaces of the guide blocks (351) have a corresponding The guide bevel (352) of the guide cone tooth (331) allows the limit gear (35) to rotate in the same direction relative to the fixed seat (31) by using the guide bevel (331) of the floating key (33) and the guide bevel (352) of the guide block (351), so that the guide block (351) of the limit gear (35) can be rotated in the same direction relative to the fixed seat (31) in sequence. The action guide groove (320) of the rotating gear (32), the high-position locking guide rail (321) and the release guide rail (322) are changed in position, and a top rod (36) is inserted into the upper part of the limit gear (35) and locked in a nut (34) that can be placed in the floating key (33), and the top rod (36) is supported on the bottom surface of the limit pin (38), and the limit pin (38) The oil pump base (10) has an enlarged end (380), and the periphery of the through hole (18) of the oil pump base (10) has a corresponding enlarged groove portion (180), so that a return spring (39) is supported between the limit pin (38) and the oil pump base (10), so that the limit pin (38) can generate a disengagement return effect after selectively penetrating the lock hole (26) of the push rod core shaft (25);

Thereby, a parking structure with a convenient operation and a locking effect and a restrictive function is constructed.

Through the above-mentioned structural design, when the parking structure with limiting function of the present invention is actually applied, as disclosed in the first and fourth figures, under the normal condition of not braking and not parking, the sliding block (330) of the floating key (33) of the locking assembly (30) and the guide block (351) of the limiting gear (35) are slidably arranged in the corresponding action guide groove (320) of the spiral gear (32) (as shown in the sixth figure), and the limiting pin (38) can be disengaged from the lock hole (26) of the push rod spindle (25) of the brake handle (20) by the action of the return spring (39), and at the same time, the floating key (33) is pushed out of the fixing seat (31) to the position to be pressed for parking;

When the brake handle (20) is pushed to the brake position and there is a need to park the vehicle, as shown in FIG. 5 , when the brake handle (20) is in the brake position, the lock hole (26) of the push rod spindle (25) of the brake handle (20) corresponds to the through hole (18) of the oil pump base (10) and the limit pin (38) of the locking assembly (30). The rider only needs to press the floating key (33) of the locking assembly (30) inward to make the floating key (33) can push the limit gear (35) upward to displace the guide block (351) of the limit gear (35) out of the range of the aforementioned action guide groove (320) [as shown in Figure 7]. At the same time, the limit gear (35) presses the limit pin (38) into the lock hole (26) of the push rod core shaft (25) through the push rod (36), and the limit pin (38) synchronously compresses the return spring (39) to generate a return preload, thereby completing the parking action. As shown in FIGS. 7 and 8, when the floating key (33) is released, the floating key (33) loses its pressing force, so the limit pin (38) and the limit gear (35) are affected by the restoring preload of the return spring (39) to produce an outward displacement, and since the guide block (351) of the limit gear (35) has been separated from the action guide groove ( 320), the guide block (351) of the limit gear (35) will enter the relatively high locking guide rail (321) of the spiral gear (32) by means of the guiding effect of its guide slope (352), so that the limit gear (35) and the limit pin (38) will not be completely retracted, so as to maintain the parking state and avoid releasing the parking state due to improper contact with the brake handle (20).

When the vehicle needs to be released from the parking position, as shown in the first, fifth and ninth figures, the brake handle (20) needs to be pushed to move toward the brake position to reduce the friction between the lock hole (26) of the push rod spindle (25) of the brake handle (20) and the limit pin (38) of the lock assembly (30). At this time, the rider needs to press the floating key (33) of the lock assembly (30) inward again, so that the floating key (33) pushes the limit gear (35) upward again, so that the guide block (351) of the limit gear (35) is disengaged from the aforementioned spiral gear. The high-position locking guide rail (321) of the limit gear (32) enters the release guide rail (322) [as shown in Figure 9], so that the guide block (351) of the limit gear (35) uses the guiding effect of the release guide rail (322) to enter the connected action guide groove (320), so that the limit gear (35) and the limit pin (38) can be completely retracted by the return spring (39), thereby achieving the purpose of releasing the parking vehicle, and the brake handle (20) is actuated by the push rod (17) to return to the brake release position for the next braking action.

As can be seen from the above structure and action description, the parking structure with limiting function of the present invention can utilize the design of the screw gear (32) in the fixing seat (31) of the locking assembly (30) so that the limit gear (35) can be moved between the action guide groove (320) of the screw gear (32), the high position locking guide rail (321) and the release guide rail (33) through repeated pressing of the floating key (33). 322), so that the floating key (33) of the locking assembly (30) needs to be repeatedly pressed to achieve the action of parking and unparking the vehicle, thereby generating a virtual locking restriction function to prevent the parking state from being released arbitrarily due to accidental touch during the parking process, thereby ensuring the safety of the vehicle during parking. At the same time, the parking and unparking actions can be performed simply and quickly, which not only has the convenience of operation but also can enhance its practicality.

Thus, it can be understood that the present invention is a creation with excellent creativity. In addition to effectively solving the problems faced by previous inventions, it also greatly improves the efficacy. In addition, there is no same or similar product creation or public use in the same technical field. At the same time, it has improved efficacy.
