[0048] Example one

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the embodiment provides a parking structure, which comprises a pull rod 101, a first parking unit 102 and a second parking unit 103. The pull rod 101 is provided with a pull rope (not shown in the figure) connected with a hand brake 122; the first parking unit 102 comprises a parking part 1021 slidingly arranged on a vehicle frame and a driving part 1022 driving the parking part 1021 to move towards or away from a wheel; the driving part 1022 comprises a first driving connecting rod 10221, a second driving connecting rod 10222 and a third driving connecting rod 10223, one end of the first driving connecting rod 10221 is pivotally arranged with the other end of the pull rod 101, the other end of the first driving connecting rod 10221 is pivotally arranged on the middle part of the second driving connecting rod 10222, one end of the second driving connecting rod 10222 is pivotally arranged with the vehicle frame, the other end of the second driving connecting rod 10222 is pivotally arranged with one end of the third driving connecting rod 10223, and the other end of the third driving connecting rod 10223 is pivotally arranged on the parking part 1021; the second parking unit 103 is arranged in the same structure as the first parking unit 102, and the first parking unit 102 and the second parking unit 103 are symmetrically arranged on the vehicle frame.

[0050] Specifically, when preparing to park, the hand brake 122 can be pulled to pull the pull rod 101 through the pull rope, and the driving part 1022 is driven to move by the pull rod 101, the first driving connecting rod 10221, the second driving connecting rod 10222 and the third driving connecting rod 10223 of the driving part 1022 can be regarded as a three-link mechanism, when the pull rod 101 is pulled by the pull rope, the first driving connecting rod 10221 drives the second driving connecting rod 10222 to rotate with the shaft hinge point of the vehicle frame as the rotation point, and further drives the third driving connecting rod 10223 to pull the parking part 1021 to move in the direction towards the wheel, when the parking part 1021 abuts against the tire tread of the wheel, a friction force is generated, and further a resistance can be provided for the wheel, the operation is convenient, the parking flexibility is good, and the good practicability is achieved.

[0051] Further, the second parking unit 103 is arranged in the same structure as the first parking unit 102, and the first parking unit 102 and the second parking unit 103 are symmetrically arranged on the vehicle frame, so that resistance can be provided for two front wheels or two rear wheels at the same time, the parking speed is accelerated, the chassis carrier vehicle is prevented from sliding on the ground with a certain slope or being pulled by people, and unnecessary loss is avoided.

[0052] As shown in Figure 1 and Figure 2 shown, the embodiment further comprises a reset spring 104, one end of the reset spring 104 is arranged on the third driving connecting rod 10223, and the other end of the reset spring 104 is arranged on the vehicle frame on the side away from the pull rod 101 of the third driving connecting rod 10223.

[0053] Specifically, in the parking state, the reset spring 104 is stretched, and when the chassis carrier needs to move, the handbrake 122 is reset to release the parking state, at which time the reset spring 104 restores the deformation and generates a rebound force to drive the third driving link 10223 to reset, thereby driving the parking part 1021 to quickly reset, moving the parking part 1021 away from the wheels. In this way, the parking structure 10 can quickly release the parking state and has good flexibility.

[0054] As shown in Figure 2 the driving part 1022 of the embodiment further includes a swing rod 10224, and the other end of the third driving link 10223 is arranged on the swing rod 10224. The parking part 1021 includes a sliding block 10211 slidingly arranged on the vehicle frame and a parking block 10212 arranged on one end of the sliding block 10211, and the other end of the sliding block 10211 is arranged in shaft hinged with the swing rod 10224 (i.e., the third driving link 10223 is arranged in shaft hinged with the sliding block 10211 through the swing rod 10224). The second driving link 10222 is provided with a strip-shaped hole 102221 for the movement of the hinged shaft at the shaft hinged position with the third driving link 10223.

[0055] Specifically, by arranging the swing rod 10224, after the parking part 1021 abuts against the wheels to achieve the parking action, the third driving link 10223 is in a vertical or forward-pulling state with the sliding block 10211 to provide the abutting force required when parking, thereby forming a stable and effective parking action.

[0056] In a preferred embodiment, the pull rope is a steel wire rope.

[0057] In a preferred embodiment, the material of the parking block 10212 is wear-resistant plastic, which can increase the friction with the tire surface of the wheels, provide resistance to the wheels, play a role in parking, and reduce damage to the tire surface.

[0058] As shown in Figure 3 the embodiment, the positioning bracket 105 is arranged on the vehicle frame, and the positioning bracket 105 is provided with a positioning hole 1051 for the pull rod 101 to pass through. In this way, when the pull rod 101 is pulled, the positioning hole 1051 can limit the movement trajectory of the pull rod 101, avoid the swing or deviation of the pull rod 101 from interfering with other components, and ensure smooth action of the parking structure 10.

[0059] As shown in Figure 6As shown, the hand brake 122 in this embodiment includes a fixed frame 1221 and a handle 1222 rotatably arranged on the fixed frame 1221, the fixed frame 1221 is provided with a ratchet (not shown in the figure), and a pull rope is arranged on the handle 1222; the handle 1222 is provided with a pawl 1224 engaged with the ratchet and a push rod (not shown in the figure) for driving the pawl 1224 to disengage from the ratchet, one end of the push rod extends out of the handle 1222 to form a button part 1223, a middle part of the push rod is provided with a protrusion (not shown in the figure) for driving the pawl 1224 to rotate, and the other end of the push rod is provided with a push spring (not shown in the figure) between the handle 1222.

[0060] In use, by rotating the handle 1222, the pull rope is synchronously pulled to drive the first parking unit 102 and the second parking unit 103 to park. The handle 1222 is limited and locked by the cooperation of the ratchet and the pawl 1224 to maintain the parking state. When it is needed to be released, the button part 1223 is pressed to move the push rod, so that the protrusion drives the pawl 1224 to disengage from the ratchet, so that the handle 1222 can be reset, that is, the parking state is released, and at the same time the push rod is reset by the push spring for next operation.
