[0091] For a thorough understanding of the present application, reference will be made to the following detailed description of the application in which the specific embodiments of the application will be described in connection with the accompanying drawings. It will be apparent to those skilled in the art that the application can be practiced without one or more of the specific details set forth herein. The detailed description of the preferred embodiments of the application is not intended to limit the scope of the application, as claimed.

[0092] First embodiment

[0093] The present application provides a vehicle transport frame. The vehicle transport frame can be a step container. The vehicle transport frame can be used for transporting vehicles 180.

[0094] Referring to Figures 1 to 3 , the vehicle transport frame comprises a base frame 110 and a movable support frame 120. The base frame 110 comprises a bottom side beam 111 and a bottom end beam. The end of the bottom side beam 111 is connected to the end of the bottom end beam to form a substantially rectangular frame.

[0095] The movable support frame 120 comprises a movable bearing plate 121 and a movable beam 122. The movable bearing plate 121 is a rectangular plate. Along the width direction of the movable bearing plate 121, both ends of the movable bearing plate 121 are connected with the movable beam 122. In this way, the movable support frame 120 forms a substantially rectangular structure. The vehicle 180 can be placed on the movable bearing plate 121. The movable support frame 120 is connected to the base frame 110. The movable support frame 120 is movably arranged between a movable retracted position and a movable expanded position.

[0096] As shown in Figure 3 , when the movable support frame 120 is in the movable retracted position, along the length direction of the base frame 110, the movable support frame 120 does not protrude out of the base frame 110. At this time, the length dimension of the vehicle transport frame is small, which facilitates the empty return transportation of the vehicle transport frame (without transporting the vehicle 180, only transporting the vehicle transport frame).

[0097] As shown in Figure 1 and Figure 2 , when the movable support frame 120 is in the movable expanded position, along the length direction of the base frame 110, the free end of the movable support frame 120 is located on the outside of the base frame 110 away from the center of the base frame 110. At this time, the length dimension of the vehicle transport frame is large, and the base frame 110 and the movable support frame 120 can be used together to carry the vehicle 180, and the vehicle transport frame can transport a larger number of vehicles 180.

[0098] When the movable support frame 120 is in the movable retracted position and in the movable expanded position, the movable bearing plate 121 is parallel to the base bearing plate 117 described below. Along the width direction of the base frame 110, the base frame 110 is provided with one movable support frame 120 on each side.

[0099] Referring to Figures 1 to 3 , the vehicle transport frame further comprises an end frame 130. The end frame 130 comprises two end columns 132 and an end cross beam 133. The two end columns 132 are arranged at intervals. The end of the end cross beam 133 is connected to one end of the end column 132. The other end of the end column 132 is pivotally connected to the corner of the base frame 110. In this way, the end frame 130 can be rotated between a folded position and an upright position. As Figure 3As shown, when the end frame 130 is in the folded position, the end frame 130 is stacked above the base frame 110. At this time, the length direction of the end column 132 is parallel to the length direction of the base frame 110. The height dimension of the vehicle transport frame is small, facilitating air return transportation.

[0100] As shown, when the end frame 130 is in the folded position, the end frame 130 is stacked above the base frame 110. At this time, the length direction of the end column 132 is parallel to the length direction of the base frame 110. The height dimension of the vehicle transport frame is small, facilitating air return transportation. Figure 1 As shown, when the end frame 130 is in the folded position, the end frame 130 is stacked above the base frame 110. At this time, the length direction of the end column 132 is parallel to the length direction of the base frame 110. The height dimension of the vehicle transport frame is small, facilitating air return transportation.

[0101] During the process of the end frame 130 rotating from the upright position to the folded position, the end cross beam 133 is flipped towards the center of the base frame 110.

[0102] The end of the end frame 130, where the end cross beam 133 is arranged, is provided with an upper corner piece 131 for stacking. As shown, Figure 9 and Figure 10 As shown, when the end frame 130 is in the folded position, the end frame 130 is stacked above the base frame 110. At this time, the length direction of the end column 132 is parallel to the length direction of the base frame 110. The height dimension of the vehicle transport frame is small, facilitating air return transportation.

[0103] In the present embodiment, the mobile support frame 120 is movably connected to the base frame 110 between the mobile retracted position and the mobile expanded position, and the frame is pivotally connected to the base frame 110 between the upright position and the folded position. Thus, when it is necessary to transport vehicles 180, the mobile support frame 120 can be moved to the mobile expanded position to extend the length of the vehicle transport frame, so that a larger number of vehicles 180 can be transported. When it is necessary to transport the vehicle transport frame, the mobile support frame 120 can be moved to the mobile retracted position to shorten the length of the vehicle transport frame, so that the end frame 130 is in the folded position to reduce the height dimension of the vehicle transport frame, so that a larger number of vehicle transport frames can be transported by one transport device at a time. The other end of the end frame 130 is provided with an upper corner piece 131 for stacking, so that when the vehicle transport frame is used to transport vehicles 180, the vehicle transport frames can be stacked by the upper corner piece 131, so that a larger number of vehicles 180 can be simultaneously transported by multiple vehicle transport frames.

[0104] Preferably, as shown, Figure 1 , Figures 3 to 5 The corner of the base frame 110 is provided with a pivot portion 113. One end of the end frame 130 is pivotally connected to the pivot portion 113. The lower end of the pivot portion 113 is provided with a lower corner piece 114. The upper end of the pivot portion 113 is provided with a support plate 115. When the end frame 130 is in the upright position, the end frame 130 is lapped to the upper surface of the support plate 115. The base frame 110 supports the end frame 130 through the support plate 115.

[0105] When the end frame 130 is stacked on the base frame 110, the upper surface of the support plate 115 is located highest in the height direction of the base frame 110. In this way, if multiple vehicle transport frames need to be stacked, the lower corner piece 114 of the vehicle transport frame located in the upper layer is lapped to the upper surface of the support plate 115 when the end frame 130 is stacked on the base frame 110. Thus, the vehicle transport frame is conveniently stacked when the end frame 130 is stacked on the base frame 110.

[0106] Please return Figure 1 and Figure 3 The base frame 110 is provided with a pivot portion 116. One end of the moving support frame 120 is pivotally connected to the pivot portion 116 to rotate between the moving retracted position and the moving expanded position. Thus, the structure of the base frame 110 is simple.

[0107] In the length direction of the base frame 110, the pivot portion 116 is located at the end of the base frame 110. The pivot portion 116 can be connected to the bottom cross beam. Thus, the structure of the base frame 110 is simple.

[0108] As shown in Figure 1 and Figure 3 The base frame 110 has a base frame bearing plate 117, a bottom cross beam and a support beam 112. The length direction of the support beam 112 is parallel to the length direction of the bottom side beam 111. In the width direction of the base frame 110, the support beam 112 is located on the inner side of the bottom side beam 111 close to the center of the base frame 110. In the width direction of the base frame 110, there is a gap between the support beam 112 and the bottom side beam 111. The base frame bearing plate 117 is located between the bottom side beam 111 and the support beam 112. The base frame bearing plate 117 is lapped to the bottom cross beam. The wheels of the vehicle 180 can be placed on the base frame bearing plate 117. When the moving support frame 120 is in the moving expanded position, the upper surface of the moving bearing plate 121 and the upper surface of the base frame bearing plate 117 are approximately flush. Thus, it is convenient for the vehicle 180 to be moved from one of the moving bearing plate 121 and the base frame bearing plate 117 to the other.

[0109] When the moving support frame 120 is in the moving retracted position, the moving support frame 120 is lapped to the base frame bearing plate 117.

[0110] As shown in Figure 1 and Figure 2 The vehicle transport frame further comprises a lead bridge 150. The moving support frame 120 comprises a lead bridge plate and a lead bridge beam 152. The lead bridge plate is a rectangular plate. In the width direction of the lead bridge plate, both ends of the lead bridge plate are connected with the lead bridge beam 152. In this way, the lead bridge 150 forms a substantially rectangular structure.

[0111] It is to be noted that when the approach bridge 150 is connected to the mobile support 120, which is connected to the base frame 110, the width direction of the approach bridge plate and the width direction of the mobile support plate 121 are parallel to the width direction of the base frame 110. When the mobile support 120 is in the mobile stowed position, the length direction of the mobile support 120 is parallel to the length direction of the base frame 110. When the approach bridge 150 is in the approach bridge stowed position, the length direction of the approach bridge 150 is parallel to the length direction of the mobile support 120.

[0112] Along the length direction of the approach bridge 150, one end of the approach bridge 150 is a connection end 151. The connection end 151 of the approach bridge 150 is connected to the mobile support 120 in the mobile deployed position. The approach bridge 150 is movable to the approach bridge deployed position.

[0113] When the mobile support 120 is in the mobile deployed position, the free end of the approach bridge 150 in the approach bridge deployed position is located outside and below the free end of the mobile support 120. At this time, the approach bridge 150 is inclined to the height direction of the base frame 110. The free end of the approach bridge 150 can be lapped onto the platform 190 (such as the ground) carrying the vehicle transportation frame. The vehicle 180 can drive to the mobile support 120 via the approach bridge 150, and then drive to the base frame 110.

[0114] Specifically, please continue to refer to Figures 1 to 3 Along the length direction of the mobile support 120, the connection end 151 is movably connected to the mobile support 120. In this way, the approach bridge 150 and the mobile support 120 form a telescopic structure, so that the approach bridge 150 can move between the approach bridge deployed position and the approach bridge stowed position. When the approach bridge 150 is in the approach bridge stowed position, the free end of the approach bridge 150 is located outside the free end of the mobile support 120 away from the base frame 110, and at the free end of the mobile support 120.

[0115] As shown in Figures 1 to 3 Along the length direction of the mobile support 120, the length dimension of the whole formed by the approach bridge 150 and the mobile support 120 is the approach bridge dimension. When the approach bridge 150 is in the approach bridge deployed position, the approach bridge dimension is the approach bridge deployed dimension. When the approach bridge 150 is in the approach bridge stowed position, the approach bridge dimension is the approach bridge stowed dimension. The approach bridge deployed dimension is greater than the approach bridge stowed dimension.

[0116] Along the length direction of the mobile support 120, the free end of the approach bridge 150 is pushed towards the center of the mobile support 120 to move the approach bridge 150 to the approach bridge stowed position, so as to shorten the approach bridge dimension. In this way, it is convenient for the empty return transportation of the vehicle transportation frame.

[0117] Preferably, neither the moving support 120 nor the approach bridge 150 protrudes the outer contour of the base frame 110 along the width direction of the base frame 110. Thus, the vehicle transportation frame is convenient to be transported by a transportation vehicle.

[0118] Please refer to Figure 1 and Figure 2 The moving beam 122 of the moving support 120 is provided with an approach bridge slot 123. The length direction of the approach bridge slot 123 is parallel to the length direction of the moving beam 122. The openings of the approach bridge slots 123 of the two moving beams 122 face each other. The approach bridge beam 152 of the approach bridge 150 is arranged in the approach bridge slot 123. In this way, the approach bridge 150 can move along the length direction of the moving support 120 between the approach bridge unfolded position and the approach bridge folded position. Thus, the connection between the approach bridge 150 and the moving support 120 is firm.

[0119] As shown in Figures 1 to 3 , the vehicle transportation frame further comprises a support leg 160. The support leg 160 can be moved to a support position. When the support leg 160 is in the support position, the length direction of the support leg 160 is parallel to the height direction of the base frame 110, the support leg 160 is located below the free end of the moving support 120, and the support leg 160 is supported on the platform 190 carrying the vehicle transportation frame. When the support leg 160 is in the support position, the free end of the moving support 120 in the moving unfolded position is overlapped with the support leg 160. In this way, the support leg 160 supports the free end of the moving support 120 in the moving unfolded position. Thus, the free end of the moving support 120 is supported on the platform 190, and the moving support 120 is not easy to be damaged.

[0120] As shown in Figure 2 and Figure 3 , the support leg 160 is pivotally connected to the free end of the moving support 120. In this way, the support leg 160 can rotate between a storage position and a support position. When the support leg 160 is in the storage position, the free end of the support leg 160 is attached to the moving support 120. At this time, the size of the support leg 160 along the height direction of the base frame 110 is small, and the empty return transportation of the vehicle transportation frame is facilitated.

[0121] Please refer to Figure 1 and Figure 2 The end of the approach bridge 150 along the length direction of the approach bridge 150 is provided with a limiting hole 153. The limiting hole 153 comprises an unfolded limiting hole located at one end of the approach bridge 150 and a folded limiting hole located at the other end of the approach bridge 150. The vehicle transportation frame further comprises a limiting assembly 170. The limiting assembly 170 comprises a limiting shaft 171. The limiting shaft 171 is movably arranged in the moving support 120 along the width direction of the moving support 120. When the approach bridge 150 is in the approach bridge unfolded position, the unfolded limiting hole is located at the limiting shaft 171. At this time, the limiting shaft 171 can be arranged in the unfolded limiting hole to fix the approach bridge 150 in the approach bridge unfolded position.

[0122] When the approach bridge 150 is in the retracted position, the retracted limiting hole is located at the limiting shaft 171. At this time, the limiting shaft 171 can pass through the retracted limiting hole to fix the approach bridge 150 in the retracted position.

[0123] The limiting shaft 171 is provided with a shaft fixing hole. The axial direction of the shaft fixing hole is parallel to the radial direction of the limiting shaft 171. The shaft fixing hole passes through the limiting shaft 171. The limiting assembly 170 also includes a locking member 173. The locking member 173 is movably connected to the movable support 120 along the axial direction of the shaft fixing hole. When the limiting shaft 171 passes through the limiting hole 153, the shaft fixing hole is located at the locking member 173. The locking member 173 can pass through the shaft fixing hole to fix the limiting shaft 171 passing through the limiting hole 153. Thus, it is possible to prevent the limiting shaft 171 from leaving the limiting hole 153.

[0124] Please continue to refer to this. Figure 1 and Figure 2 The limiting assembly 170 also includes a locking frame 174 and an elastic element 175. The locking frame 174 can be a sheet metal part. The locking frame 174 is connected to the movable support 120. The locking frame 174 is provided with a locking frame hole. The axial direction of the locking frame hole is parallel to the axial direction of the shaft fixing hole. The locking member 173 passes through the locking frame hole. The elastic element 175 can be a cylindrical spring. The elastic element 175 is sleeved on the locking member 173. One end of the elastic element 175 abuts against the locking frame 174. The other end of the elastic element 175 abuts against the locking member 173. The elastic element 175 is in a deformed (compressed or stretched) state. The elastic element 175 in the deformed state can apply a force to the locking member 173. This force can cause the locking member 173 to move toward the limiting shaft 171, and then extend into the shaft fixing hole. Therefore, when the shaft fixing hole is aligned with the locking member 173, the locking member 173 can automatically extend into the shaft fixing hole under the action of the elastic member 175. The elastic member 175 can also keep the locking member 173 in the state of extending into the shaft fixing hole.

[0125] The vehicle transport frame also includes a fixed sleeve 176 and an operating lever 172. The operating lever 172 is connected to the outer peripheral surface of the limiting shaft 171. The length direction of the operating lever 172 is perpendicular to the axial direction of the limiting shaft 171. Thus, the limiting shaft 171 can be moved by the operating lever 172.

[0126] Please continue to refer to this. Figure 1 and Figure 2A fixed sleeve 176 is fitted onto a limiting shaft 171. The fixed sleeve 176 is connected to a movable support 120. The fixed sleeve 176 is provided with a limiting hole 178. The limiting hole 178 penetrates the fixed sleeve 176. The axial direction of the limiting hole 178 is parallel to the radial direction of the fixed sleeve 176. The head of the locking member 173 passes through the limiting hole 178. This protects the head of the locking member 173, preventing it from bending and being unable to enter the shaft fixing hole. The fixed sleeve 176 is provided with a clearance notch 177. When the limiting shaft 171 passes through the limiting hole 153, the operating rod 172 is located within the clearance notch 177. At this time, the clearance notch 177 can block the operating rod 172, thereby blocking the rotation of the limiting shaft 171, thus preventing the head of the locking member 173 from misaligning with the shaft fixing hole and being unable to enter the shaft fixing hole. With the operating lever 172 located outside the clearance notch 177, the limiting shaft 171 moves away from the guide bridge 150. In this way, by having the operating lever 172 overlap the outer side of the fixing sleeve 176 along the width direction of the base frame 110 away from the guide bridge 150, the limiting shaft 171 can be prevented from passing through the limiting hole 153.

[0127] like Figure 9 As shown, the vehicle transport frame also includes a reinforcing component 140. With the movable support frame 120 in the movable unfolded position and the end frame 130 in the upright position, one end of the reinforcing component 140 is located on the outer side of the end frame 130 away from the center of the base frame 110 and is detachably connected to the movable support frame 120. The other end of the reinforcing component 140 extends obliquely upward and is detachably connected to the end frame 130. The length direction of the reinforcing component 140 is inclined to the height direction of the base frame 110. Thus, the end frame 130, the reinforcing component 140, and the movable support frame 120 form a triangular structure. Therefore, the reinforcing component 140 can reinforce the movable support frame 120 in the movable unfolded position.

[0128] It is understood that, in embodiments not shown, when the movable support is in the movable extended position, the reinforcing component may also be located below the movable support. In this case, one end of the reinforcing component is connected to the movable support, and the other end of the reinforcing component extends obliquely downward and is detachably connected to the end of the base frame to form a triangular structure.

[0129] Please refer to Figures 6 to 8 The method for moving vehicle 180 to the vehicle transport rack is as follows:

[0130] The movable support frame 120 is positioned in the movable deployment position, the approach bridge 150 is positioned in the approach bridge deployment position, and the outrigger 160 is positioned in the support position; the vehicle 180 travels sequentially via the approach bridge 150 and the movable support frame 120 located at one end of the base frame 110 to the movable support frame 120 located at the other end of the base frame 110; after the vehicle transport frame is filled with the vehicle 180, the approach bridge 150 is positioned in the approach bridge retracted position, and the outrigger 160 is positioned in the storage position.

[0131] Second Implementation Method

[0132] The differences between the second implementation method and the first implementation method include the following points.

[0133] like Figure 11 As shown, in the second embodiment, the pivot portion 218 is located inside the end of the base frame 210 along the length direction of the base frame 210. The pivot portion 218 and the end of the base frame 210 are spaced apart along the length direction of the base frame 210. The pivot portion 218 overlaps and is welded to the upper surface of the base frame support plate 217.

[0134] When the movable support 220 is in the movable unfolded position, the upper surface of the movable support plate 221 is higher than the upper surface of the base frame support plate 217. The vehicle transport frame is also equipped with a guide ramp 219. The guide ramp 219 is inclined in the height direction of the base frame 210. Along the length direction of the base frame 210, the upper end of the guide ramp 219 is further away from the center of the base frame 210 than the lower end of the guide ramp 219. The upper end of the guide ramp 219 extends to the upper surface of the movable support plate 221, and the lower end of the guide ramp 219 extends to the upper surface of the base frame support plate 217. Thus, when the vehicle moves from one of the base frame support plate 217 and the movable support plate 221 to the other, the guide ramp 219 can protect both the vehicle and the vehicle transport frame.

[0135] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described again here.

[0136] Third Implementation Method

[0137] The differences between the third implementation method and the first implementation method include the following points.

[0138] Please refer to Figures 12 to 15 The movable support 320 is movably connected to the base frame 310 along the length of the base frame 310 between the retracted position and the extended position. In this way, the movable support 320 and the base frame 310 constitute a telescopic structure.

[0139] More preferably, such as Figure 12 , Figure 13 and Figure 15As shown, the base frame 310 includes a bottom side beam 311 and a support beam 312. Along the width direction of the base frame 310, the support beam 312 is located inside the bottom side beam 311 near the center of the base frame 310. The length direction of the support beam 312 is parallel to the length direction of the bottom side beam 311. A gap exists between the support beam 312 and the bottom side beam 311 along the width direction of the base frame 310. Both the support beam 312 and the bottom side beam 311 are provided with a sliding groove 318. The length direction of the sliding groove 318 is parallel to the length direction of the bottom side beam 311. The opening of the sliding groove 318 of the support beam 312 faces the bottom side beam 311. The opening of the sliding groove 318 of the bottom side beam 311 faces the support beam 312. The sliding beam 322 of the movable support frame 320 is disposed within the sliding groove 318. Thus, the movable support frame 320 can move along the length direction of the sliding groove 318 between a retracted position and a deployed position. Therefore, the connection between the movable support 320 and the base frame 310 is secure.

[0140] Please refer to Figures 12 to 15 The base frame 310 is provided with a first stop hole 319. The movable support frame 320 is provided with two second stop holes 324. The two second stop holes 324 include a retractable stop hole and an extendable stop hole. The retractable stop hole is located at the free end of the movable support frame 320. The extendable stop hole and the retractable stop hole are spaced apart along the length of the movable support frame 320. The vehicle transport frame also includes a stop member 390. The stop member 390 can be a pin. When the movable support frame 320 is in the retracted position, the first stop hole 319 is located at the retractable stop hole. At this time, the stop member 390 passes through the first stop hole 319 and the retractable stop hole to lock the movable support frame 320 in the retracted position. Thus, it is possible to prevent the movable support frame 320 from leaving the retracted position.

[0141] like Figure 13 As shown, when the movable support 320 is in the movable unfolded position, the first stop hole 319 is located at the unfolded stop hole. At this time, the stop member 390 passes through the first stop hole 319 and the unfolded stop hole to lock the movable support 320 in the movable unfolded position. Thus, it is possible to prevent the movable support 320 from leaving the movable unfolded position.

[0142] Please return Figure 12 and Figure 14 The connecting end is detachably connected to the free end of the movable support 320. Thus, when a vehicle needs to be loaded onto or unloaded from the vehicle transport rack, the approach axle 350 can be connected to the movable support 320 via the connecting end to facilitate the vehicle's movement onto the vehicle transport rack. When the vehicle does not need to be loaded onto or unloaded from the vehicle transport rack, the approach axle 350 can be removed.

[0143] The free end of the movable support 320 is provided with a handle 326. The connecting end is provided with a hook portion 353. The opening of the hook portion 353 faces downward. The hook portion 353 is used to hook onto the handle 326. This facilitates the connection of the guide bridge 350 to the movable support 320. When the guide bridge 350 is removed, the handle 326 can be held to operate the movable support 320.

[0144] like Figure 15 As shown, the base frame 310 is also provided with a receiving portion 317 for accommodating the approach bridge 350. When the approach bridge 350 is removed, it can be fixed in the receiving portion 317 to prevent loss. The bottom side beam 311 is provided with a receiving inlet 316 communicating with the receiving portion 317. Along the width direction of the base frame 310, the opening of the receiving inlet 316 faces outward from the center of the base frame 310. The approach bridge 350 can be disposed in the receiving portion 317 via the receiving inlet 316.

[0145] Preferably, such as Figure 14 As shown, the support leg 360 is pivotally connected to the approach bridge 350. This allows the support leg 360 to rotate between a retracted position and a supported position. When the support leg 360 is in the retracted position, its free end rests against the approach bridge 350. At this time, the dimension of the support leg 360 along the height direction of the approach bridge 350 is small, facilitating the retraction of the approach bridge 350 into the receiving portion 317 of the base frame 310. When the hook portion 353 hooks onto the handle 326, and the support leg 360 is in the supported position, the free end of the movable support frame 320 overlaps with the support leg 360, thereby supporting the platform via the support leg 360.

[0146] The other settings of the third embodiment are largely the same as those of the first embodiment, and will not be described again here.
