Technical Field

[0001] This application relates to the field of transportation equipment technology, and in particular to a vehicle body connection device and transportation equipment. Background Technology

[0002] In modern manufacturing, flatbed trailers of various models and specifications are frequently used in workshops. The length and width of a flatbed trailer are fixed, as is the load-bearing area of ​​the platform. When the length between the support points of the goods exceeds the length of the flatbed trailer, it is impossible to use a flatbed trailer for transportation. In this case, a larger flatbed trailer or two flatbed trailers are required for transportation.

[0003] If two flatbed trucks are used for transportation, due to differences in transportation friction resistance and the performance parameters of the vehicles themselves, the two flatbed trucks are prone to relative movement during operation, making it difficult to maintain synchronization and thus endangering the safety of cargo transportation.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0055] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar words used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "front," "back," and "bottom" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0056] like Figures 1-3 As shown in the figure, this application embodiment provides a vehicle body connection device 100. The vehicle body 200 includes a first vehicle body 210 and a second vehicle body 220 arranged longitudinally. The vehicle body connection device 100 includes at least one carrier member 10 and a plurality of connecting components 20. The carrier member 10 is disposed between the first vehicle body 210 and the second vehicle body 220. The connecting components 20 are disposed at the ends of the carrier member 10, and the carrier member 10 is connected to the first vehicle body 210 and the second vehicle body 220 respectively through the connecting components 20, so that the first vehicle body 210 and the second vehicle body 220 are connected longitudinally.

[0057] Here, it can be understood that the first vehicle body 210 and the second vehicle body 220 are arranged front and back along the length direction, and the vehicle body connecting device 100 connects the originally independent first vehicle body 210 and second vehicle body 220 in the length direction, so that the two vehicles form a whole vehicle group that can be transported at the same time and keep synchronized in the front and back when transporting at the same time. This can prevent the relative displacement of the first vehicle body 210 and the second vehicle body 220 in the length direction, thereby avoiding safety problems caused by asynchrony when the two vehicles are transported.

[0058] When the first vehicle body 210 and the second vehicle body 220 move asynchronously due to differences in frictional resistance and performance parameters, such as the first vehicle body 210 leading or lagging behind the second vehicle body 220, the load-bearing component 10 can bear and transmit tensile or thrust forces through its own structural strength. The connecting component 20 is located at the end of the load-bearing component 10 and is fixed to the first vehicle body 210 and the second vehicle body 220 respectively, ensuring that there is no relative sliding between the load-bearing component 10 and the vehicle body 200, thereby ensuring the overall stability of the vehicle body 200 during operation.

[0059] Specifically, when the entire vehicle group carrying goods travels from the second vehicle body 220 towards the first vehicle body 210, if the first vehicle body 210 tends to lead due to lower frictional resistance, the load-bearing component 10 will be subjected to tension through the components connected to the first vehicle body 210, and this tension will be transmitted to the second vehicle body 220, thus suppressing the leading of the first vehicle body 210. If the second vehicle body 220 tends to lead, the load-bearing component 10 will transmit thrust to the first vehicle body 210 through the connecting component 20, thus restraining the leading of the second vehicle body 220. In this way, the relative movement of the first vehicle body 210 and the second vehicle body 220 is restricted, avoiding large relative displacements caused by asynchrony, thereby ensuring the stability and safety of the equipment during dual-vehicle transportation.

[0060] In some embodiments, when connecting to form an integral vehicle group, the carrier 10 is first placed between the first vehicle body 210 and the second vehicle body 220, with its two ends corresponding to the ends of the vehicle body 200. Then, the carrier 10 is connected to the first vehicle body 210 and the second vehicle body 220 respectively through the connecting components 20 at the ends of the carrier 10, so that the first vehicle body 210 and the second vehicle body 220 form a continuous integral vehicle group in the length direction.

[0061] When transporting larger items, it is not necessary to use large-sized and large-scale transport vehicles. Two smaller-sized vehicles can be connected together for transport, which can save costs.

[0062] This embodiment of the application, by providing a vehicle body connecting device 100 between the longitudinally arranged first vehicle body 210 and second vehicle body 220, forms a continuous integral vehicle group with the first vehicle body 210 and second vehicle body 220 in the length direction. This increases the transportation length, expands the load-bearing range of the first vehicle body 210 and second vehicle body 220, and allows the first vehicle body 210 and second vehicle body 220 to remain synchronized, thereby improving the applicability of transportation. Furthermore, it ensures that the first vehicle body 210 and second vehicle body 220 maintain front-to-back synchronization when transporting simultaneously, improving transportation safety. In addition, the load-bearing component 10 has a certain load-bearing capacity, allowing goods to rest on it, increasing the effective load-bearing area of ​​the vehicle body 200 and improving its effective load-bearing capacity.

[0063] In some embodiments, the specifications and dimensions of the carrier 10 can be designed according to the transport capacity of the vehicle body 200. For example, a larger carrier 10 can be designed for larger cargo.

[0064] In some embodiments, the first vehicle body 210 and the second vehicle body 220 are both flatbed vehicles, and the rear of the two vehicles are connected by the vehicle body connecting device 100. The entire vehicle group can travel in the front and rear directions of the first vehicle body 210 to achieve bidirectional travel and improve the convenience of the entire vehicle group.

[0065] In some embodiments, the first vehicle body 210 can be a flatbed truck and the second vehicle body 220 can be a semi-trailer, or the first vehicle body 210 can be a semi-trailer and the second vehicle body 220 can be a flatbed truck, etc.

[0066] In some embodiments, the vehicle body 200 may be provided with a first mounting portion 230, and the connecting assembly 20 may include a second mounting portion 21 and a first locking member 22. The second mounting portion 21 is disposed at the end of the support member 10. The first mounting portion 230 and the second mounting portion 21 are connected by the first locking member 22.

[0067] Here, the first mounting part 230 is disposed at the end of the vehicle body 200, and the second mounting part 21 is disposed at the end of the carrier 10. The first locking member 22 applies a locking force to fix the first mounting part 230 and the second mounting part 21 together, so that the carrier 10 and the vehicle body 200 form a whole without relative sliding, thereby ensuring that the first vehicle body 210 and the second vehicle body 220 do not move relative to each other during transportation.

[0068] The locking action of the first locking member 22 can eliminate the installation gap, so that the first mounting part 230 and the second mounting part 21 fit tightly together. Even if the vehicle encounters external forces such as bumps and vibrations during transportation, the rigidity of the connection can be maintained, preventing the load-bearing member 10 from loosening or shifting between the vehicle body 200, and ensuring the continuity and reliability of the constraint force transmission.

[0069] The first locking component 22 is a detachable locking connection, which facilitates the quick assembly of the carrier component 10 and the vehicle body 200 before transportation, and also allows the vehicle body 200 to be easily separated from the carrier component 10 after transportation by disassembling the first locking component 22, without affecting the independent use of a single vehicle body 200, thus taking into account both the needs of dual-vehicle collaborative transportation and the flexibility of a single vehicle.

[0070] In some embodiments, the first locking element 22 may be a bolt, pin, etc.

[0071] In some embodiments, the first mounting portion 230 may include a plurality of first hook ears 231, which are distributed laterally at intervals along the vehicle body 200. The second mounting portion 21 includes a plurality of second hook ears 211, which are also distributed laterally at intervals along the vehicle body 200. The plurality of first hook ears 231 and the plurality of second hook ears 211 are arranged alternately. The first hook ears 231 are provided with first mounting holes 212, and the second hook ears 211 are provided with second mounting holes 232. The first locking member 22 passes through the first mounting holes 212 and the second mounting holes 232 to connect the carrier member 10 to the vehicle body 200.

[0072] It can be understood that the first lug 231 is distributed at intervals along the width direction of the vehicle body 200, and the second lug 211 is distributed at the end of the bearing member 10. When the two are arranged in an alternating manner, a single first lug 231 can be embedded between two adjacent second lugs 211 to form an alternating structure similar to "gear meshing".

[0073] In this way, the tensile or thrust generated during transportation can be distributed to multiple connection points, and the force between the load-bearing component 10 and the vehicle body 200 can be dispersed from multiple points, avoiding the breakage of the lug due to concentrated force at a single point. This can improve the connection strength between the load-bearing component 10 and the vehicle body 200, and improve the stability of the connection between the load-bearing component 10 and the vehicle body 200.

[0074] After the first mounting hole 212 of the first lug 231 and the second mounting hole 232 of the second lug 211 are staggered and precisely aligned, the first locking member 22 passes through the aligned mounting holes and can tightly lock the staggered lugs, so that the bearing member 10 and the vehicle body 200 form a multi-point rigid connection in the width direction, ensuring that the force transmission can be evenly distributed on multiple lugs, thereby improving the shear and tensile resistance of the overall connection structure.

[0075] Specifically, when the vehicle body 200 or the load-bearing component 10 is subjected to lateral torsional force (such as the vehicle body 200 tilting due to uneven road surface), the staggered lug structure can offset part of the torsional torque by mutually restraining each other, reducing the deformation of the connection parts, thereby maintaining the relative position stability of the load-bearing component 10 and the vehicle body 200, and further ensuring the safety of equipment transportation.

[0076] like Figure 4 As shown, in some embodiments, the carrier 10 may include a first connecting beam 11 and a second connecting beam 12. The first connecting beam 11 is provided with a plurality of first adjustment holes and is connected to the first vehicle body 210 via a connecting assembly 20. The inner wall of the first connecting beam 11 is provided with a sliding groove 111. The second connecting beam 12 is provided with a plurality of second adjustment holes and is connected to the second vehicle body 220 via a connecting assembly 20. The second connecting beam 12 is configured to move along the sliding groove 111 in a controlled manner, causing the carrier 10 to extend or retract longitudinally along the vehicle body 200. A second locking member 13 passes through the first adjustment holes and the second adjustment holes to connect the first connecting beam 11 and the second connecting beam 12.

[0077] Here, the multiple adjustment holes provide multiple fixing positions, allowing selection of appropriate hole positions according to actual length requirements. The second locking element 13 then secures the holes, ensuring that the first connecting beam 11 and the second connecting beam 12 do not move relative to each other during transportation, and guaranteeing synchronization between the first vehicle body 210 and the second vehicle body 220. Furthermore, adjustment only requires moving the second connecting beam 12 to the appropriate position and securing it with the second locking element 13, facilitating installation and disassembly, improving loading and unloading efficiency, and without affecting the overall strength and stability of the load-bearing component 10.

[0078] Specifically, the first connecting beam 11 is located on the side closer to the first vehicle body 210, and the second connecting beam 12 is located on the side closer to the second vehicle body 220. The second connecting beam 12 can move along the sliding groove 111 on the inner wall of the first connecting beam 11, allowing the second connecting beam 12 and the first connecting beam 11 to extend and retract relative to each other, thereby changing the overall length of the load-bearing member 10. After adjusting to a suitable length, the second locking member 13 passes through the corresponding first and second adjustment holes to fix the first connecting beam 11 and the second connecting beam 12, making the length of the load-bearing member 10 stable and adaptable to different cargo support point spacings or the connection requirements of two vehicles.

[0079] This embodiment allows the first connecting beam 11 and the second connecting beam 12 to move relative to each other, so that the load-bearing member 10 can be extended or shortened within a certain range, which can adapt to the transportation of goods of different specifications. When the distance between the support points of the goods changes, there is no need to replace the load-bearing member 10, thus expanding the applicability of the vehicle body connecting device 100.

[0080] In some embodiments, both the first connecting beam 11 and the second connecting beam 12 are box girders.

[0081] In some embodiments, the vehicle body connecting device 100 may include a plurality of carrier members 10 arranged laterally at intervals, with a reinforcing member 30 provided between two adjacent carrier members 10, and the two ends of the reinforcing member 30 being connected to the first connecting beam 11 respectively.

[0082] Here, multiple load-bearing components 10 are distributed in parallel, distributing the constraint force originally borne by a single load-bearing component 10 to multiple load-bearing components 10, thereby reducing the load on a single load-bearing component 10 and improving the overall load-bearing capacity of the vehicle body connection device 100. The lateral connection of the reinforcement 30 further integrates the dispersed load-bearing components 10 into a stable frame structure, significantly improving the bending and shear resistance of the vehicle body connection device 100.

[0083] The reinforcement member 30 connects to the first connecting beam 11 of the adjacent load-bearing member 10, forming a rigid lateral support, so that multiple load-bearing members 10 form an overall frame that shares the load. When a load-bearing member 10 tends to deform due to excessive local stress during transportation, the reinforcement member 30 will transfer the force to the adjacent load-bearing member 10, using the rigidity of the overall structure to offset the local stress, avoiding overload damage to a single load-bearing member 10, thereby improving the stability and practicality of the vehicle body connection device 100.

[0084] The reinforcement 30 can quickly transfer the force borne by a single load-bearing component 10 to other load-bearing components 10, avoid localized force concentration, reduce the risk of overall connection failure due to fatigue damage of individual load-bearing components 10, and extend the service life of the vehicle body connection device 100.

[0085] In some embodiments, see Figure 2 The number of support members 10 is 2. In other embodiments, the number of support members 10 can be set according to actual needs, such as 3, 4, 5, 6, etc.

[0086] like Figure 5 and Figure 6 As shown, in some embodiments, the vehicle body connecting device 100 may further include a support assembly 40 disposed at the bottom of the first connecting beam 11. The support assembly 40 includes a support leg 41 and a base plate 42. The support leg 41 is rotatably connected to the first connecting beam 11. The base plate 42 is disposed at the end of the support leg 41 away from the first connecting beam 11, and the base plate 42 is provided with a third mounting portion 421. The third mounting portion 421 is connected to the third lug 112 of the first connecting beam 11 via a third locking member 43.

[0087] Here, when the vehicle body connecting device 100 is installed between the first vehicle body 210 and the second vehicle body 220, the support assembly 40 can provide bottom support for the first connecting beam 11, making the installation of the vehicle body connecting device 100 more convenient and saving machinery and labor. When the vehicle body connecting device 100 is not used, the support assembly 40 can also be used to directly support the load-bearing component 10 on the storage site for direct storage.

[0088] The support leg 41 works in conjunction with the base plate 42 for support. The base plate 42 increases the contact area with the ground, expands the force-bearing area, and improves the support capacity of the support component 40, making the support more stable.

[0089] The support leg 41 is rotatably connected to the first connecting beam 11. When the support assembly 40 is not needed, the support leg 41 can be folded away, saving space. Simultaneously, the third mounting part 421 is connected to the third lug 112 on the first connecting beam 11 via a third locking member 43, which secures the support leg 41 to the third lug 112, preventing it from shaking or being damaged during transport due to vibration or bumps. The locking function of the third locking member 43 prevents the support leg 41 from accidentally moving during support, thus ensuring the safety of cargo transportation.

[0090] When support is needed, the support leg 41 can be rotated to a position perpendicular to the first connecting beam 11, so that the base plate 42 contacts the ground. The rotatable design of the support leg 41 allows it to flexibly switch between the use state and the storage state, without affecting the transportation process, and can quickly provide support when needed.

[0091] In some embodiments, the third locking element 43 may be a pin, bolt, etc.

[0092] like Figure 7 As shown in the illustration, this application also provides a transportation device 1000, which may include a vehicle body 200 and the aforementioned vehicle body connecting device 100. The vehicle body 200 includes a first vehicle body 210 and a second vehicle body 220 arranged longitudinally. The vehicle body connecting device 100 is disposed between the first vehicle body 210 and the second vehicle body 220, and is connected to both the first vehicle body 210 and the second vehicle body 220.

[0093] In the transportation equipment 1000 of this application embodiment, the first vehicle body 210 and the second vehicle body 220 are connected together by a carrier 10, which increases the transportation length, improves the applicability of transportation, and ensures that the first vehicle body 210 and the second vehicle body 220 maintain synchronization when transporting simultaneously. Furthermore, the carrier 10 has a certain load-bearing capacity, allowing goods to rest on it, increasing the effective load-bearing area of ​​the vehicle body 200 and improving its effective load-bearing capacity.

[0094] The vehicle body 200 serves as the basic carrier for transportation. The first vehicle body 210 and the second vehicle body 220 are rigidly connected in the length direction through the vehicle body connecting device 100, so that the constraint force transmitted by the vehicle body connecting device 100 can act more efficiently on the two vehicle bodies 200, further suppressing relative movement, thereby ensuring stable transportation of goods on the overall vehicle group.

[0095] like Figures 8-13As shown, in some embodiments, the vehicle body 200 may be provided with a fourth mounting portion 240, and the transport equipment 1000 may also include a mounting device 300 for connecting the connecting assembly 20 of the vehicle body connecting device 100 to the vehicle body 200. The mounting device 300 includes a lever 310, which is rotatably connected to the fourth mounting portion 240. The lever 310 is connected to a first locking member 22 of the vehicle body connecting device 100. When the lever 310 rotates, it pushes the first locking member 22 into the first mounting hole 212 of the vehicle body 200 and the second mounting hole 232 of the vehicle body connecting device 100, thereby connecting the connecting assembly 20 to the vehicle body 200.

[0096] Here, the fourth mounting part 240 of the vehicle body 200 provides a pivot point for the lever 310, which is connected to the first locking member 22. When the lever 310 is rotated, the lever principle is used to reduce the force required to push the first locking member 22. The operator can move the first locking member 22 with a smaller force and accurately push it into the first mounting hole 212 and the second mounting hole 232, which can more easily complete the locking operation and greatly improve the installation efficiency. This completes the locking connection between the second mounting part 21 and the first mounting part 230, thereby achieving a stable assembly of the load-bearing member 10 and the vehicle body 200.

[0097] In this embodiment, the rotation trajectory of the lever 310 is fixed, which can guide the first locking member 22 to accurately enter or exit the mounting hole, enabling quick installation or disassembly. The operator only needs to rotate the lever 310 to complete the installation or disassembly of the first locking member 22, simplifying the operation process, eliminating the need for complicated tools, saving time, reducing the difficulty of operation, and improving the overall ease of use of the transportation equipment 1000.

[0098] In some embodiments, the end of the lever 310 away from the fourth mounting portion 240 is provided with a handle, which can further facilitate the operation by the operator.

[0099] In some embodiments, the first locking member 22 includes a tube body and a locking part. The tube body is made of steel tubing, which reduces the overall weight of the first locking member 22. The tube body has an opening through which the fourth locking member 320 passes. The locking part is a pin that inserts into the first mounting hole 212 and the second mounting hole 232. The end of the pin away from the tube body is machined into a tapered shape to facilitate insertion into the first mounting hole 212 and the second mounting hole 232. The tube body and the pin are connected by welding.

[0100] In some embodiments, the mounting device 300 may further include a fourth locking member 320, which passes through the first locking member 22 and the lever member 310 to connect the lever member 310 to the first locking member 22. The lever member 310 is provided with a waist-shaped hole 330, which moves along the fourth locking member 320 when the lever member 310 rotates.

[0101] Here, the fourth locking member 320 passes through the first locking member 22 and the lever member 310, connecting the first locking member 22 and the lever member 310. The oblong hole 330 on the lever member 310 provides room for its rotation. When the lever member 310 rotates, the oblong hole 330 moves along the fourth locking member 320, allowing the lever member 310 to rotate flexibly within a specific range. The oblong hole 330 can compensate for the change in the distance from the hinge point to the center of the first locking member 22 during the rotation of the lever member 310 around the support hinge point, thus realizing the transmission of force.

[0102] The engagement between the waist-shaped hole 330 and the fourth locking member 320 allows the rotation of the lever member 310 to be unrestricted by rigidity, and can accommodate slight displacement between the lever member 310 and the first locking member 22, which is conducive to the first locking member 22 accurately passing through the first mounting hole 212 and the second mounting hole 232.

[0103] In some embodiments, the fourth locking element 320 may be a pin, bolt, etc.

[0104] In some embodiments, the mounting device 300 may further include a guide 340 disposed on the vehicle body 200, and the first locking member 22 passes through the guide hole of the guide 340. The lever member 310 includes a first portion 311 and a second portion 312 at a preset angle, the preset angle being any value between 15° and 25°, for example, 15°, 18°, 20°, 22°, or 25°.

[0105] Here, the guide member 340 is set on the vehicle body 200, and the guide hole allows the first locking member 22 to pass through. It can provide precise guidance for the movement of the first locking member 22, limit its displacement in non-preset directions, and make the first locking member 22 move stably along a predetermined trajectory. This can improve the stability and accuracy of the movement of the first locking member 22 and improve the reliability of the installation device 300.

[0106] The first part 311 and the second part 312 of the lever 310 are at a preset angle, which can cleverly avoid the guide 340 and prevent spatial interference between the two during the movement, so that the lever 310 can rotate smoothly along the preset trajectory without being obstructed by the guide 340.

[0107] In this way, the components can operate in a coordinated manner within a limited space, avoiding interference between components and improving the overall smoothness of the installation device 300. At the same time, this structural design is simple and practical, eliminating the need for complex obstacle avoidance mechanisms, simplifying the structure of the installation device 300 while ensuring functionality, and reducing manufacturing and assembly difficulties.

[0108] In some embodiments, a first locking member 22 is disposed at the connection between the first portion 311 and the second portion 312, the second portion 312 is connected to the fourth mounting portion 240, and a handle is provided at the end of the first portion 311 away from the second portion 312. It is understood that the first portion 311 is a lever arm that saves effort, and the second portion 312 is a resistance arm; the greater the ratio of the length of the second portion 312 to the length of the first portion 311, the more effort is saved.

[0109] The preset angle is set between 15° and 25°. This prevents the first part 311 and the second part 312 of the lever 310 from getting too close due to an angle that is too small, causing spatial interference between the lever 310 and the guide 340 and affecting the rotational flexibility of the lever 310. Conversely, an angle that is too large will make the overall structure of the lever 310 too loose, increasing the space occupied by the mounting device 300. Within this range, the lever 310 can maintain a reasonable structural compactness while avoiding the guide 340, ensuring smooth cooperation with other components during rotation.

[0110] In this embodiment, when assembling the first vehicle body 210 and the second vehicle body 220, the support assembly 40 is used to place the carrier 10 on a flat surface. The first mounting portions 230 on the first vehicle body 210 and the second vehicle body 220 are respectively brought close to and aligned with the second mounting portions 21 of the connecting assembly 20, achieving alignment of the first hanging ear 231 and the second hanging ear 211. Afterwards, the positions of the two vehicles can be adjusted forward, backward, left, right, up, and down. After the first mounting hole 212 and the second mounting hole 232 are aligned, the lever 310 is moved to push the first locking member 22 into the second mounting hole 232 on the first hanging ear 231 and the first mounting hole 212 on the second hanging ear 211 to complete the connection. After successful connection, the second vehicle body 220 on one side of the second connecting beam 12 is moved and adjusted to the required length of the carrier 10, and then the second locking member 13 is locked. Then, by raising the vehicle body 200 so that the support assembly 40 is not under force, the support assembly 40 is rotated and suspended below the first connecting beam 11 by the third locking member 43. This completes the installation of the entire vehicle assembly, which is then ready for transport. Disassembly can be performed by repeating the reverse steps when the entire vehicle assembly is no longer needed.
