Furthermore, the ability to remove the mobile frame assembly from the vehicle frame and the ladder assembly from the front platform assembly increases the product's loading capacity, reduces fuel consumption and transportation costs, and ultimately improves the user experience.

[0016] 2. By connecting the two first support beams to the connecting frame, multiple guide components are respectively installed on the side walls of the two first support beams and made to fit against the inner wall of the frame. This allows the two first support beams to move synchronously with the connecting frame when the connecting frame moves, thereby enabling the first support beams to drive the guide components to move along the inner wall of the frame. This prevents the connecting frame, the two first support beams, and the two first connecting beams from shifting during movement, thus improving the stability of the movement of the connecting frame, the two first support beams, and the two first connecting beams.

[0017] 3. By mounting two first springs on the outside of the two guide rods respectively, connecting one end of the two first springs to the guide seat, and connecting the other end of the two first springs to the first support beam, the first support beam supports the guide seat through the two first springs, thereby using the two first springs to correct the deviation of the first support beam and the connecting frame, so as to improve the stability of the moving connecting frame.

[0018] 4. By installing two first mounting brackets on the two inner walls of the frame respectively, and installing two first buffer seats on the two first mounting brackets respectively, with the two first buffer seats facing the two first support beams respectively, the first buffer seats can limit the first support beams when the two first support beams are retracted into the frame, thereby improving the user experience of the product; by installing two second buffer seats at the ends of the frame, with the two second buffer seats facing the connecting bracket, the second buffer seats will fit against the connecting bracket when the connecting bracket moves to the frame, thereby limiting the connecting bracket and preventing rigid contact between the connecting bracket and the frame, further improving the user experience of the product.

[0019] 5. By setting the support part on the second support beam and placing the first support beam on the support part, the second support beam supports the first support beam through the support part, thereby improving the stability of the movement of the first support beam.

[0020] 6. By embedding the support roller into the first support groove, the support roller is rotatably connected to the first support seat, and the support roller is made to fit against the bottom of the fixed beam, so that the first support seat supports the support roller, thereby enabling the support roller to rotate in the first support groove, and thus enabling the support roller to support the fixed beam, thereby reducing the coefficient of friction between the fixed beam and the second support beam, and improving the stability of the fixed beam movement.

[0021] 7. By installing two L-shaped limiting plates on both sides of the fixed beam away from the connecting frame, the fixed beam supports the two limiting plates, thereby enabling the fixed beam and the two limiting plates to move synchronously. By installing two second mounting brackets on the bottom of the frame near the connecting frame, and installing two third buffer seats on the two second mounting brackets respectively, with the two third buffer seats facing the two limiting brackets, the frame supports the third buffer seats through the second mounting brackets. This allows the limiting brackets to fit against the third buffer seats when the fixed beam is moved out of the frame, thereby limiting the fixed beam and improving the user experience of the product.

[0022] 8. By installing two second support seats on both sides of the connecting frame, installing two connecting parts on the bottom of the two platform frames, embedding the two connecting parts into the two second support slots, and rotatably connecting the connecting parts with the second support seats, the second support seats support the platform frames through the connecting parts, thereby enabling the platform frames to rotate relative to the vehicle frame; by rotatably connecting the two platform frames to two tilting cylinders, the tilting cylinders can drive the platform frames to rotate, thereby adjusting the tilt angle of the platform frames.

[0023] 9. By fitting the second spring onto the outside of the pull rod, connecting one end of the second spring to the locking plate, and connecting the other end of the second spring to the locking frame, the locking frame supports the locking plate through the second spring. This utilizes the spring force of the second spring to ensure that the locking rod is embedded in the drawer assembly, further enhancing the stability of the drawer assembly.

[0024] 10. By embedding at least a portion of the drawer ladder body into the first receiving groove, distributing multiple locking holes on both sides of the drawer ladder body, and embedding a locking rod into one locking hole, the locking rod can be embedded into different locking holes when the drawer ladder body is in the first receiving groove, thereby adjusting the extension length of the drawer ladder body to improve the applicability of the product.

Detailed Implementation

[0026] The following are specific implementation cases and appendices. Figures 1 to 9 The present invention will be further described, but the present invention is not limited to these embodiments.

[0027] A vehicle transport vehicle expansion platform, such as Figures 1 to 9As shown, the vehicle transport vehicle expansion platform includes: a frame 10, movable cylinders 11, a movable frame assembly 12, a fixed beam 13, a traction rod 14, a connecting ring 15, a connecting shaft 16, a front platform assembly 17, a tilting cylinder 18, a first receiving slot 19, a ladder assembly 20, and a locking assembly 21; two movable cylinders 11 are installed inside the frame 10; the movable frame assembly 12 is located inside the frame 10, and the movable frame assembly 12 is simultaneously connected to the output ends of the two movable cylinders 11; the fixed beam 13 is a hollow cavity with openings at both ends, and the fixed beam is connected to the movable frame assembly 12; at least a portion of the traction rod 14 is embedded in the fixed beam 13; the connecting ring 15 is ring-shaped. The front platform assembly 17 is rotatably connected to the top of the mobile frame assembly 12; two tilting cylinders 18 are rotatably connected to both sides of the frame 10, and the output ends of the two tilting cylinders 18 are rotatably connected to both sides of the front platform assembly 17; two first receiving slots 19 are disposed in the front platform assembly 17; two drawer ladder assemblies 20 are respectively embedded in the two first receiving slots 19; multiple locking assemblies 21 are installed on the front platform assembly 17, and the multiple locking assemblies 21 are respectively connected to the two drawer ladder assemblies 20.

[0028] By installing two movable cylinders 11 inside the frame 10, the movable frame assembly is located inside the frame 10. The movable frame assembly 12 is simultaneously connected to the output shafts of the two movable cylinders 11, so that the frame 10 supports the two movable cylinders 11. This allows the two movable cylinders 11 to work together to drive the movable frame assembly 12 to move, thereby enabling the movable frame assembly 12 to extend outside the frame 10 and increase the overall area of ​​the product. By connecting the fixed beam 13 to the movable frame assembly 12, at least a portion of the traction rod 14 is embedded in the fixed beam 13, so that the movable frame assembly 12 supports the fixed beam 13. This allows the movable frame assembly 12 and the fixed beam 13 to move synchronously, thereby enabling the traction rod 14 to move within the fixed beam 13 and adjust the overall length of the fixed beam 13 and the traction rod 14. By installing a ring-shaped connecting ring 15 at the end of the traction rod 14, the main vehicle can move through the connecting ring 15 and the traction rod 14, thereby using the connecting ring 15 to drive the traction rod 14 to move. By rotatably connecting the bottom of the front platform assembly 17 to the top of the mobile frame assembly 12, rotatably connecting the two tilting cylinders 18 to the two sides of the frame 10, and rotatably connecting the output ends of the two tilting cylinders 18 to the two sides of the front platform assembly 17 respectively, the mobile frame assembly 12 can drive the front platform assembly 17 to move when the mobile frame assembly 12 moves. At this time, the mobile frame assembly 12 will drive the two tilting cylinders 18 to rotate so that the two tilting cylinders 18 adapt to the position of the front platform assembly 17. Thus, the two tilting cylinders 18 cooperate to drive the front platform assembly 17 to rotate, thereby adjusting the tilt angle of the front platform assembly 17. In this way, when the vehicle to be transported is placed on the front platform assembly 17, the tilt angle of the front platform assembly 17 can be adjusted to adapt to the parking posture of the vehicle, thereby improving the applicability of the product. By placing two first receiving slots 19 inside the front platform assembly 17 and embedding two drawer ladder assemblies 20 into the two first receiving slots 19 respectively, the drawer ladder assemblies 20 can move within the first receiving slots 19, thereby adjusting the overall length of the drawer ladder assemblies 20 and the front platform assembly 17; by installing multiple locking components 21 on the front platform assembly 17 and connecting the multiple locking components 21 to the two drawer ladder assemblies 20 respectively, the locking components 21 can fix the drawer ladder assemblies 20 inside the front platform assembly 17, thereby improving the stability of the drawer ladder assemblies 20.

[0029] In actual use of the product, firstly, activate the two moving cylinders 11, causing them to work together to move the moving frame assembly 12 and the fixed beam 13, thereby removing the moving frame assembly 12 from the frame 10. When the moving frame assembly 12 is removed from the frame 10, it will drive the front platform assembly 17 to move, and cause the tilting cylinder 18 to rotate with the front platform assembly 17. Then, activate the locking assembly 21 to disengage it from the ladder-drawing assembly 20. Next, pull the ladder-drawing assembly 20 out of the first receiving slot 19. Then, activate the locking assembly 21 to fix the ladder-drawing assembly 20 inside the front platform assembly 17, thereby improving the stability of the ladder-drawing assembly 20. Finally, activate the two tilting cylinders 18, causing them to work together to move the front platform assembly 12 and the fixed beam 13. Platform assembly 17 rotates, causing the front platform assembly 17 to tilt, facilitating the vehicle's movement onto the front platform assembly 17 and the frame 10. Then, two tilting cylinders 18 are activated, cooperating to rotate the front platform assembly 17, adjusting its tilt angle to suit the vehicle's parking posture. Next, the connecting shaft 16 is pulled out from the moving frame assembly 12, the fixed beam 13, and the tow bar 14. Then, the tow bar 14 is pulled out from the fixed beam 13, and the main vehicle is connected to the tow bar 14 using a connecting ring 15. When the tow bar 14 has moved a predetermined length from the fixed beam 13, the connecting shaft 16 is passed sequentially through the moving frame assembly 12, the fixed beam 13, and the tow bar 14, thereby fixing the tow bar 14 within the fixed beam 13.

[0030] By adopting the above structure, the mobile frame assembly 12 can move within the frame 10, and the ladder assembly 20 can move within the front platform assembly 17. This allows the mobile frame assembly 12 to be hidden within the frame 10 and the ladder assembly 20 to be hidden within the front platform assembly 17 when the vehicle is not loaded, thereby reducing the space occupied by the product. At the same time, it avoids the hidden dangers of excessive length and width, ensuring that the product meets road inspection requirements. This allows the mobile frame assembly 12 to be moved out of the frame 10 and the ladder assembly 20 to be moved out of the front platform assembly 17, thereby increasing the product's loading capacity, reducing fuel consumption and transportation costs, and ultimately improving the user experience of the product.

[0031] Specifically, connecting nuts are fitted at both ends of the connecting shaft 16, and the two connecting nuts are respectively engaged with the moving frame assembly 12 and the fixed beam 13 to fix the traction rod 14 inside the fixed beam 13.

[0032] In embodiments of the present invention, such as Figure 4As shown, the movable frame assembly 12 further includes: a connecting frame 121, a first support beam 123, a first connecting beam 124, and a guide assembly 125; the connecting frame 121 is provided with an installation groove 122, and the fixed beam 13 is installed in the installation groove 122; two first support beams 123 are connected to the connecting frame 121, and the two first support beams 123 are located on both sides of the installation groove 122; two first connecting beams 124 are connected to the connecting frame 121, and the two first connecting beams 124 are respectively connected to the output ends of the two movable cylinders 11, and the first connecting beams 124 are located on the side of the first support beam 123 near the fixed beam 13; multiple guide assemblies 125 are respectively installed on the side walls of the two first support beams 123, and the multiple guide assemblies 125 are respectively attached to the two inner walls of the frame 10.

[0033] By setting the mounting slot 122 inside the connecting frame 121 and installing the fixing beam 13 inside the mounting slot 122, the fixing beam 13 is connected to the connecting frame 121, thereby making the fixing beam 13 hidden inside the connecting frame 121. By connecting the two first connecting beams 124 to the connecting frame 121 and connecting the two first connecting beams 124 to the output ends of the two moving cylinders 11 respectively, the two moving cylinders 11 can drive the two first connecting beams 124 to move, thereby driving the connecting frame 121 and the fixing beam 13 to move, and thus changing the relative position of the connecting frame 121 and the fixing beam 13 with the frame 10. By connecting the two first support beams 123 to the connecting frame 121, and installing multiple guide components 125 on the side walls of the two first support beams 123 respectively, and making the multiple guide components 125 fit against the inner wall of the frame 10, the two first support beams 123 move synchronously with the connecting frame 121 when the connecting frame 121 moves. This allows the first support beams 123 to drive the guide components 125 to move along the inner wall of the frame 10, thereby preventing the connecting frame 121, the two first support beams 123, and the two first connecting beams 124 from shifting during movement, thus improving the stability of the movement of the connecting frame 121, the two first support beams 123, and the two first connecting beams 124.

[0034] In embodiments of the present invention, such as Figure 5As shown, the guide assembly 125 includes: a guide seat 1251, a guide wheel 1252, a guide rod 1253, a first spring 1254, and a limiting plate 1255; the guide seat 1251 is provided with a guide groove, and the guide seat 1251 is located on the side of the first support beam 123 opposite to the first connecting beam 124; the guide wheel 1252 is embedded in the guide groove, the guide wheel 1252 is rotatably connected to the guide seat 1251, and the guide wheel 1252 is in contact with the inner wall of the frame 10; two guide rods 1253 pass through the guide seat. The two guide rods 1253 are connected to the first support beam 123 on both sides of the guide rod 1251; the two first springs 1254 are respectively fitted on the outside of the two guide rods 1253, one end of the two first springs 1254 is connected to the guide seat 1251, and the other end of the two first springs 1254 is connected to the first support beam 123; the two limiting plates 1255 are respectively connected to the two guide rods 1253, and the limiting plates 1255 are located on the side of the guide seat 1251 away from the first support beam 123.

[0035] By embedding the guide wheel 1252 into the guide groove of the guide seat 1251, the guide wheel 1252 is rotatably connected to the guide seat 1251, and the guide wheel 1252 is made to fit against the inner wall of the frame 10, so that the guide seat 1251 supports the guide wheel 1252, allowing the guide wheel 1252 to rotate within the guide seat 1251, thereby enabling the guide wheel 1252 to roll along the inner wall of the frame 10; by passing two guide rods 1253 through both sides of the guide seat 1251 and connecting the two guide rods 1253 to the first support beam 123, the first support beam 123 is... Two guide rods 1253 drive the guide seat 1251 to move. Two first springs 1254 are respectively fitted onto the outside of the two guide rods 1253, with one end of each spring connected to the guide seat 1251 and the other end connected to the first support beam 123. This allows the first support beam 123 to support the guide seat 1251 via the two springs 1254, thereby correcting the alignment of the first support beam 123 and the connecting frame 121 and improving the stability of the connecting frame 121's movement. Two limiting plates 1255 are respectively connected to the two guide rods 1253 and positioned on the side of the guide seat 1251 away from the first support beam 123. This limits the guide seat 1251, preventing the guide rods 1253 from moving out of the guide seat 1251 and improving the user experience.
