These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] like Figure 1-Figure 4 As shown, a movable buffer shock-absorbing frame has a chassis frame 1, the frame includes a shock-absorbing structure, the shock-absorbing structure includes a leaf spring assembly 2, the leaf spring assembly 2 includes a first leaf spring piece 201 located at the bottom, and an arc-shaped second leaf spring piece 202 located at the upper part, the leaf spring assembly 2 also includes a top leaf spring piece 203 formed by multiple arc sections and located above the second leaf spring piece 202, the end of the top leaf spring piece 203 is connected with the upwardly wound end of the second leaf spring piece 202 to form a cavity in which a transfer wheel 3 can be placed and allow the transfer wheel 3 to produce a certain forward and backward movement, the cavity includes a starting cavity part for placing the transfer wheel 3, and a movable cavity part for the transfer wheel 3 to move forward and backward toward the center direction of the leaf spring assembly 2 when vibrated; the two ends of the transfer wheel 3 are connected to the chassis support 4, and the chassis support 4 can be detachably and fastened to the chassis frame 1. When the leaf spring assembly is affected by vibration and deforms under the action of load, each leaf slides relative to each other and generates friction, which produces a certain resistance, causing the vibration of the chassis frame to attenuate. The transfer wheel 3 is placed in a cavity formed by the end of the top leaf spring 203 and the upwardly wound end of the second leaf spring 202. The transfer wheel 3 produces a certain movement in the cavity, so that the transfer wheel 3 obtains a certain buffer space, reducing the up and down vibration amplitude of the transfer wheel 3, thereby reducing the vibration energy transmitted from the transfer wheel 3 to the chassis frame 1 through the chassis support 3, and further reducing the vibration of the chassis frame.

[0018] Specifically, another optional implementation is that the first arc segment of the top plate spring 203 and the winding portion of the end of the second leaf spring 202 form a starting cavity, the second arc segment of the top plate spring 203 and the straight segment of the second leaf spring 202 form a movable cavity, the transfer wheel 3 can move forward and backward from the starting cavity to the movable cavity, the third arc segment of the top plate spring 203 and the straight segment of the second leaf spring 202 form a blocking cavity, the maximum diameter of the blocking cavity is smaller than the diameter of the transfer wheel 3 to block the further forward and backward movement of the transfer wheel 3. Figure 4The dotted line in the figure indicates the position where the transmission wheel 3 moves to the movable cavity. The transmission wheel 3 forms a certain forward and backward movement in the movable cavity, further reducing the up and down vibration amplitude of the transmission wheel 3, so that the vibration of the chassis frame is further reduced.

[0019] Specifically, another optional implementation is that there is more than one leaf spring between the top leaf spring 203 and the second leaf spring 202, and the two ends of the more than one leaf spring added between the top leaf spring 203 and the second leaf spring 202 are gradually retracted from top to bottom. Specifically, another optional implementation is that the two ends of the multiple leaf springs added between the first leaf spring 201 and the second leaf spring 202 are gradually retracted from top to bottom. The multiple leaf springs that are gradually retracted from top to bottom generate different friction forces from top to bottom.

[0020] Specifically, another optional embodiment is that the two ends of the transmission wheel 3 are connected to the chassis support 4 in the following manner: including an I-shaped connecting piece 501, and the two sides of the I-shaped connecting piece 501 have side connecting pieces, and the side connecting pieces on both sides are respectively placed between the two ends of the transmission wheel 3 and the chassis support 4, and the transmission wheel 3 and the side connecting pieces are connected to the corresponding chassis support 4 through detachable fasteners. The detachable fasteners can be, for example, fasteners composed of bolts and nuts.

[0021] Specifically, another optional embodiment is that the two ends of the transmission wheel 3 are connected to the chassis support 4 in the following manner: comprising two independent single-sided connecting pieces 502, the two ends of the transmission wheel 3 are respectively connected to the lower parts of the two single-sided connecting pieces 502, and the upper parts of the two single-sided connecting pieces 502 are connected to the corresponding chassis support 4 through detachable fasteners. The detachable fasteners may be, for example, fasteners composed of a combination of bolts and nuts.

[0022] Specifically, another optional implementation is that the bottom of the first leaf spring 201 is supported on the surface of the sleeve 9 through the support base 6, and the top of the top leaf spring 203 is provided with a cover plate 7. The cover plate 7, the leaf spring assembly 2, and the support base 6 are buckled on the surface of the sleeve 9 through a U-shaped detachable fastener 8, and the sleeve 9 is sleeved on the outer wall of the connecting shaft 11 used to connect the driving wheels 10 on both sides. When the driving wheel is vibrated, the vibration force is transmitted to the support base and the leaf spring assembly through the sleeve and then to the transmission wheel. The leaf spring assembly attenuates the vibration, and the transmission wheel 3 is placed in the cavity formed by the end of the top leaf spring 203 and the upwardly wound end of the second leaf spring 202. The transmission wheel 3 generates a certain amount of movement in the cavity, so that the transmission wheel 3 obtains a certain buffer space, reduces the up and down vibration amplitude of the transmission wheel 3, and further reduces the vibration of the chassis frame.

[0023] Specifically, another optional implementation is as follows: Figure 1As shown, the chassis frame 1 includes two transverse beams and a longitudinal beam connecting the two transverse beams, and the two groups of chassis supports 4 corresponding to the two groups of leaf spring assemblies 2 are detachably fastened to the two transverse beams.
