DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1-2 , is the first embodiment of the present utility model, which provides a shock absorbing mechanism for a flatbed transport semi-trailer, comprising:

[0027] The external component 100 includes a vehicle body 101, a vehicle frame 102 is plugged into the lower surface of the vehicle body 101, a shock absorbing component 200 is provided on the vehicle frame 102, and a cargo box 103 is fixedly connected to the side of the vehicle frame 102 via a locating pin;

[0028] In addition, the shock absorbing assembly 200 includes an ear plate 201 fixedly connected to the bottom of the frame 102, the inner side of the ear plate 201 is fixedly connected to the anti-seismic bending plate 202, the inner cavity of the anti-seismic bending plate 202 is fixedly connected to the inner clamping strip 203, the inner clamping strip 203 is engaged with the external gear 204, the end face of the external gear 204 is fixedly connected to the plug shaft 205, and the bottom of the plug shaft 205 is cooperated with a damping rod 207.

[0029] Specifically, the coordinated arrangement of the vehicle body 101, the vehicle frame 102 and the cargo compartment 103 enables the semi-trailer to transport goods and exert its transportation capacity. The fixed connection between the ear plate 201 and the seismic bent plate 202 allows the seismic bent plate 202 to stably absorb vibrations and bumps, providing the vehicle body 101 with a first layer of smooth driving effect. When the damping rod 207 is subjected to a bumpy force, the force can be transmitted to the outer gear 204 through the rotational movement of the plug shaft 205. At the same time, under the guidance of gravity, the inner clamping strip 203 and the outer gear 204 complete the engagement. The inner clamping strip 203 can limit the movement of the outer gear 204, and then transmit the torque to the damping rod 207 again through the plug shaft 205. The coordinated cooperation between these parts can repeatedly absorb vibrations and shaking internally, and can also meet the shock absorption needs of long-term transportation of the semi-trailer.

[0030] Furthermore, the outer surface of the plug shaft 205 is rotatably connected to a stabilizing top plate 206, the lower surface of the stabilizing top plate 206 is fixedly connected to a damping rod 207, the lower surface of the damping rod 207 is fixedly connected to a transmission rod 208, the end face of the transmission rod 208 is plugged with a wheel 209, and the transmission rod 208 is cooperated with a secondary shock-absorbing component 300.

[0031] Preferably, the fixed connection between the top plate 206 and the damping rod 207 is stabilized, and the top of the damping rod 207 is made more stable and firm by adding a counterweight, which reduces the displacement of the damping rod 207. The plug-in connection between the transmission rod 208 and the wheel 209 allows the wheel 209 to better meet the transportation needs. The coordinated setting of the secondary shock-absorbing component 300 can absorb the vibration when the wheel 209 deviates from the position, and reduce the overall vibration of the semi-trailer from as many aspects as possible.

[0032] When in use, first install the cargo compartment 103 and the frame 102 in order and on the vehicle body 101, then fix the ear plate 201 on the bottom of the frame 102, and fix the anti-seismic bent plate 202 on the inner side of the ear plate 201. Then, an inner clamping strip 203 is fixedly provided in the inner cavity of the anti-seismic bent plate 202, and then the outer gear 204 is sleeved on one end of the plug shaft 205, and the outer surface is rotatably sleeved with a stable top plate 206, and then the damping rod 207 is fixedly installed on the lower surface of the stable top plate 206, and the wheel 209 is inserted and installed on the end face of the transmission rod 208, and then the transmission rod 208 is inserted in the inner cavity of the damping rod 207 for shock absorption of the semi-trailer.

[0033] In summary, through the coordinated arrangement of the vehicle body 101, the vehicle frame 102 and the cargo compartment 103, the semi-trailer can transport goods and exert its transportation capacity. The fixed connection between the ear plate 201 and the seismic bending plate 202 can allow the seismic bending plate 202 to stably absorb vibrations and bumps, providing the vehicle body 101 with a first layer of smooth driving effect; when the damping rod 207 is subjected to a bumpy force, the force can be transmitted to the outer gear 204 through the rotational movement of the plug shaft 205. At the same time, under the guidance of gravity, the inner clamping strip 203 and the outer gear 204 complete the engagement, and the inner clamping strip 203 can limit the movement of the outer gear 204, and then transmit the torque to the damping rod 207 again through the plug shaft 205. The coordinated cooperation between these parts can repeatedly absorb vibrations and shaking internally, and can also meet the shock absorption needs of long-term transportation of the semi-trailer.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the auxiliary shock-absorbing effect of the secondary shock-absorbing component 300.

[0036] Specifically, the secondary shock-absorbing assembly 300 includes an upright spring 301 on the outer surface of the transmission rod 208 , the top of the upright spring 301 is fixedly connected to a buffer sleeve rod 302 , and the top of the buffer sleeve rod 302 is fixedly connected to the lower surface of the seismic bending plate 202 .

[0037] Furthermore, the fixed connection between the upright spring 301 and the buffer sleeve 302 supports the lower surface of the seismic bending plate 202. At the same time, when the seismic bending plate 202 is at the lowest point, the effects of gravity and shaking force are most prominent. The upright spring 301 can significantly offset these external forces, protecting the integrity of the physical structure of the seismic bending plate 202. The seismic bending plate 202 can also provide long-term shock absorption for the semi-trailer.

[0038] Preferably, there are multiple wheels 209 , which are symmetrically arranged at the bottom of the frame 102 .

[0039] Among them, the symmetrical arrangement of the wheels 209 provides more sufficient support for the frame 102, so that the frame 102 can remain relatively stable when following the semi-trailer, ensuring smooth driving of the frame 102.

[0040] Afterwards, the damping rod 207 is an integrally formed rubber damper, and the maximum rotation range of the damping rod 207 is 75 degrees.

[0041] In the above, the 75-degree rotation range setting of the damping rod 207 can reduce turning vibration when the semi-trailer is driving, ensuring stable transportation efficiency.

[0042] When in use, first, several wheels 209 are symmetrically arranged at the bottom of the frame 102, then the buffer sleeve 302 is fixedly assembled at the bottom of the seismic bending plate 202, and then the upright spring 301 is fixedly installed at the bottom of the buffer sleeve 302. The bottom end face of the upright spring 301 is fixedly installed to the outer surface of the transmission rod 208, which is used to absorb vibration when the semi-trailer turns.

[0043] In summary, the lower surface of the seismic bending plate 202 is supported by the fixed connection between the upright spring 301 and the buffer sleeve 302. At the same time, when the seismic bending plate 202 is at the lowest point, the effects of gravity and shaking force are most prominent. The upright spring 301 can significantly offset these external forces, protect the integrity of the physical structure of the seismic bending plate 202, and the seismic bending plate 202 can also provide long-term shock absorption for the semi-trailer.

[0044] Example 3

[0045] Reference Figure 2-4 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the long-term energy absorption effect of the seismic bending plate 202.

[0046] Specifically, there are a plurality of inner clamping strips 203 , which are equidistantly arranged in the inner cavity of the anti-seismic bending plate 202 .

[0047] Furthermore, the equidistant arrangement of the inner clamping strips 203 allows the meshing of the outer gear 204 to be limited and guided, making the motion trajectory of the outer gear 204 more stable and firm, thereby indirectly improving the efficiency of the damping rod 207 in supporting and absorbing energy.

[0048] Preferably, the offset angle of the secondary shock absorbing assembly 300 is consistent with the offset angle of the damping rod 207 , the anti-seismic bending plate 202 is an integrally formed magnesium-aluminum alloy curved plate, and the side of the anti-seismic bending plate 202 is coated with anti-rust liquid.

[0049] Among them, the offset angle of the secondary shock-absorbing component 300 is consistent with that of the damping rod 207, so that when the semi-trailer turns or bumps, the vibration can be evenly absorbed by the secondary shock-absorbing component 300 and the damping rod 207, avoiding certain components from bearing excessive energy absorption pressure, and indirectly extending the shock absorption life of these components. The anti-seismic bending plate 202 is coated with anti-rust liquid, which can protect the external structure of the anti-seismic bending plate 202 and improve the physical properties of the anti-seismic bending plate 202.

[0050] When in use, first arrange several inner clips 203 in the inner cavity of the anti-seismic bending plate 202, then make the damping rod 207 and the secondary shock-absorbing component 300 keep the offset angle consistent, and then apply anti-rust liquid on the side of the anti-seismic bending plate 202 for external protection of the anti-seismic bending plate 202.

[0051] In summary, by equidistantly arranging the internal clamping strips 203, the meshing of the external gear 204 is guided by limiting, and the movement trajectory of the external gear 204 is more stable and firm, which indirectly improves the efficiency of the damping rod 207 in supporting energy absorption; the secondary shock-absorbing component 300 and the damping rod 207 have the same offset angle, so that when the semi-trailer turns or bumps, the vibration can be evenly absorbed by the secondary shock-absorbing component 300 and the damping rod 207, avoiding certain components from bearing excessive energy absorption pressure, and indirectly extending the shock absorption life of these components.
