The reset speed of the second time delay reset element 10 (the reset speed of a spring 12 in this embodiment) is faster than the reset speed of the first time delay reset element 3.
The first time delay reset element 3 is mounted on the frame 4. The first time-delay reset element 3 can be a gas spring or a gas tension spring or a damper. In the first embodiment, a gas spring is adopted, the push rod of the gas spring is always pushed downwards (outwards) during normal unbraking, and the push rod of the gas spring is compressed upwards (inwards) during braking, and energy is stored. The scheme can also adopt an air tension spring (see a fifth embodiment), the pull rod of the air tension spring always pulls back downwards (inwards) during normal braking, and the pull rod of the air tension spring is pulled upwards (outwards) during braking, and stores energy. The scheme can also adopt a damper, the principle is the same, and the description is omitted here.
The linkage mechanism 2 is arranged between the foot brake 1 and the first time delay reset element 3, one end of the linkage mechanism 2 is connected to the foot brake 1, and the other end of the linkage mechanism 2 is connected to the movable end 31 of the first time delay reset element 3. The linkage mechanism 2 can be a lever, a folding rod or a combination of a guide wheel and a pull rope, and can be in other forms as long as the linkage effect of the scheme can be realized. In the first embodiment, the linkage mechanism 2 adopts a lever, the fulcrum 21 of the lever is fixed on the frame 3, the lever is provided with a chute 22 corresponding to the fulcrum 21, the lever is arranged on the frame 3 by inserting the fulcrum 21 on the chute 22, and the chute 22 can ensure smooth linkage action when the lever rotates. One end of the lever is connected to the movable end 31 of the first delay reset element 3, and the other end of the lever is connected to the foot brake 1.
Further, in the optimized structure of the foot brake 1 according to the first embodiment, the foot brake seat 11 is connected with the other end of the lever of the linkage mechanism 2, the foot brake seat 11 is provided with the slot 14, the brake block 13 is provided with the insert rod 15, the insert rod 15 is inserted into the slot 14, the brake block 13 is arranged below the foot brake seat 11, a release limiting structure is further arranged between the insert rod 15 and the slot 14, the insert rod 15 cannot be released from the slot 14, the spring 12 is arranged between the top of the insert rod 15 and the bottom of the slot 14, and the brake block is always pressed downwards by the spring 12.

In an initial state (brake release) of the embodiment of the utility model, the first time delay reset element 3 (gas spring) is in a natural state, the push rod is pushed out downwards (outwards) from the cylinder, the movable end 31 of the first time delay reset element 3 drives the linkage mechanism 2 (lever) to rotate around the pivot 21, at this time, the linkage mechanism 2 (lever) drives the foot brake 1 to ascend and leave the ground, and the frame 4 can move by means of the wheels 41.
When in use, the braking process comprises the following steps: the user steps on the foot brake 1 (the foot brake 1 descends), the foot can leave the foot brake 1, at the moment, the brake block 13 keeps in contact with the ground under the action of the spring 12 to generate friction, so that the frame 4 is positioned, the frame 4 cannot move through the wheels 41, and the purpose of braking is achieved. Simultaneously, the foot brake 1 drives the linkage mechanism 2 (lever) to rotate around the fulcrum 21, and the linkage mechanism 2 (lever) compresses the push rod of the gas spring upwards (inwards) back into the cylinder through the movable end 31, so that the first delay reset element 3 stores energy. Moreover, the brake block 13 is pressed against the ground more closely under the action of the spring 12 without leaving immediately, thereby further ensuring the positioning of the frame 4 and facilitating the parking of the vehicle by the user.
When the foot brake 1 is released, the linkage mechanism 2 cannot rotate at a large angle within a certain time because of the delay reset characteristic of the first delay reset element 3, and the foot brake 1 temporarily maintains a braking function under the action of the spring 12, so that a user can park a vehicle further conveniently. In the whole braking process, the user only needs to step on the foot brake 1 once, and does not need to step on all the time, so that the operation is more convenient.
The brake release process comprises the following steps: and as time goes by, the energy storage of the first time delay reset element 3 is delayed to release, the time delay reset element 3 is slowly reset, and the push rod of the air spring is pushed out downwards again, so that the foot brake 1 is delayed to be driven to lift upwards by the linkage mechanism 2 to leave the ground, and the frame 4 can move again by means of the wheels 41, so that the brake releasing purpose is realized. In the whole brake releasing process, the time delay reset element 2 is matched with the linkage mechanism 2 to complete the automatic time delay, so that the situation that the frame cannot move due to the fact that brake releasing is not performed is avoided.
The second embodiment of the present utility model, as shown in fig. 5 and 6, is different from the first embodiment in that the second time delay reset element 10 is a gas spring, and the brake block 13 is mounted at the outer end of the push rod of the gas spring, that is, the gas spring is used to replace the foot brake seat 11 and the spring 12. In the second embodiment, the gas spring always presses the brake block 13 downward to press the brake block 13, so that the brake block 13 keeps contact with the ground and the like, thereby producing friction. In this second embodiment, the return speed of the gas spring is faster than the return speed of the first time delay return element 3. Of course, the second time delay reset element 10 may also adopt an air tension spring, and the brake block 13 is mounted at the outer end of the tension rod of the air tension spring, which is not illustrated and described herein.

Simultaneously, the foot brake 1 drives the linkage mechanism 2 (lever) to rotate, and the linkage mechanism 2 (lever) pulls out the pull rod of the air tension spring upwards (outwards) through the movable end 31, so that the first delay reset element 3 stores energy. The linkage mechanism 2 cannot rotate at a large angle within a certain time, the brake block 13 is pressed against the ground more tightly under the action of the second delay reset element 10 and cannot leave immediately, the foot brake 1 temporarily keeps a braking function to enable the frame 4 to be positioned, and a user can park the vehicle conveniently.
