[0001] This application relates to the technical field of vehicle engineering, specifically to a vehicle body and a vehicle. Background Technology

[0002] A "beam transport vehicle" is a special engineering vehicle used to transport large precast concrete beams at railway and highway bridge construction sites. These bridge components are usually enormous and require the assembly of multiple vehicle body components to meet the transportation needs of large precast concrete beams. Therefore, how to easily and quickly assemble beam transport vehicles is one of the key issues in transporting large precast concrete beams. Summary of the Invention

[0003] The purpose of this application is to provide a vehicle body and a vehicle.

[0004] This application provides a vehicle body, the vehicle body comprising: a plurality of vehicle body components, each vehicle body component including a plurality of snap-fit ​​portions; a drive assembly, the drive assembly including a drive motor and a lead screw, the drive motor being connected to the lead screw and the drive motor being used to drive the lead screw to rotate; at least one connecting assembly, the connecting assembly being disposed between adjacent vehicle body components, the connecting assembly including a pressing block and a plurality of snap-fit ​​members, the plurality of snap-fit ​​members being spaced apart in a first direction, the pressing block being disposed between adjacent snap-fit ​​members, the pressing block being connected to the lead screw in a second direction, the rotation of the lead screw causing the pressing block to move in the second direction, the snap-fit ​​members forming an inclined force-bearing surface in the first direction, the pressing block forming an inclined pushing surface in the first direction, the pushing surface abutting against the force-bearing surface, the pressing block causing the snap-fit ​​members to move closer to or further away from the snap-fit ​​portions in the first direction through the cooperation of the pushing surface and the force-bearing surface, the first direction intersecting the second direction.

[0005] In one exemplary embodiment of this application, the compression block has two pushing surfaces in the first direction, and the distance between the two pushing surfaces gradually increases from the outside to the inside in the second direction. Each of the adjacent snap-fit ​​members in the first direction has a force-receiving surface, and the distance between the two force-receiving surfaces gradually increases from the outside to the inside in the second direction.

[0006] In one exemplary embodiment of this application, when the pressing blocks move toward each other in the second direction, the force-bearing surface and the pushing surface slide relative to each other, causing the latching members to move closer to each other in the first direction, away from the latching portion; when the pressing blocks move away from each other in the second direction, the force-bearing surface and the pushing surface slide relative to each other, causing the latching members to move away from each other in the first direction, closer to the latching portion.

[0007] In one exemplary embodiment of this application, at least one of the connecting components includes a first connecting component and a second connecting component that are correspondingly disposed. The first connecting component and the second connecting component are spaced apart in the second direction. The pressing block of the first connecting component and the pressing block of the second connecting component are respectively connected to the lead screw in the second direction. The rotation of the lead screw causes the pressing blocks to move towards each other or away from each other in the second direction, thereby causing the snap-fit ​​member of the first connecting component and the snap-fit ​​member of the second connecting component to move closer to or further away from the corresponding snap-fit ​​portion in the first direction.

[0008] In one exemplary embodiment of this application, the latching member includes a first latching member, a second latching member, a third latching member, and a fourth latching member, and the compression block includes a first compression block and a second compression block; the first latching member, the second latching member, and the first compression block are configured as the first connecting assembly; the third latching member, the fourth latching member, and the second compression block are configured as the second connecting assembly; wherein, the first compression block and the second compression block are spaced apart in the second direction, the first compression block is disposed between the first latching member and the second latching member in the first direction, and the second compression block is disposed between the third latching member and the fourth latching member in the first direction.

[0009] In one exemplary embodiment of this application, the connecting assembly further includes a first guide rod and a second guide rod, the first guide rod passing through an adjacent snap-fit ​​member in a first direction, and the second guide rod passing through the compression block in a second direction.

[0010] In one exemplary embodiment of this application, the connecting assembly further includes an elastic element, which is sleeved on the first guide rod.

[0011] In one exemplary embodiment of this application, the vehicle body assembly includes a first housing forming a receiving cavity; the vehicle body further includes a reinforcing assembly disposed in the receiving cavity, the reinforcing assembly including a plurality of connectors and a plurality of support frames, the plurality of support frames being spaced apart along a third direction, the plurality of connectors being disposed at least on opposite sides of the support frames, each connector having a plurality of slots along the third direction, the connectors engaging with the support frames through the slots, the third direction, the second direction, and the first direction being perpendicular to each other.

[0012] In one exemplary embodiment of this application, the vehicle body further includes a composite component disposed on the vehicle body assembly. The composite component includes a wear-resistant layer, a fiber layer, and an anti-corrosion layer stacked in a direction from near the vehicle body assembly to away from the vehicle body assembly.

[0013] This application also provides a vehicle including the aforementioned body.

[0014] The vehicle body and vehicle proposed in this application have the following advantages: The vehicle body includes a drive assembly, multiple body components, and at least one connecting assembly. Each body component has multiple snap-fit ​​portions. The drive assembly includes a drive motor and a lead screw, with the drive motor connected to the lead screw and used to drive the lead screw to rotate. The connecting assembly is located between adjacent body components and includes a pressing block and multiple snap-fit ​​members. The multiple snap-fit ​​members are spaced apart in a first direction, and the pressing block is located between adjacent snap-fit ​​members. In a second direction, the pressing block is connected to the lead screw, and rotation of the lead screw causes the pressing block to move in the second direction. The snap-fit ​​members form an inclined force-bearing surface in the first direction, and the pressing block forms an inclined pushing surface in the first direction. The pushing surface and the force-bearing surface abut against each other. The pressing block, through the cooperation of the pushing surface and the force-bearing surface, causes the snap-fit ​​members to move closer to or further away from the snap-fit ​​portions in the first direction. The first direction intersects with the second direction. This design makes the assembly between adjacent body components more flexible and convenient. The extrusion block is moved in a second direction by a lead screw. The interaction of the inclined force-bearing surface and the pushing surface converts the displacement in the second direction into the displacement in the first direction, adjusting the position of the locking component in the first direction. This allows the locking component to move closer to or further away from the locking part, thus achieving the engagement and disengagement of the locking component with the locking part. This structure reduces the operational complexity of traditional mechanical connection methods, making vehicle body assembly more convenient. Due to its modular design, vehicle body components can be flexibly combined according to actual needs, adapting to the requirements of different transportation tasks. Compared to the fixed structure of traditional beam transport vehicles, this adjustable connection method significantly improves the versatility and ease of operation of the equipment, and reduces maintenance costs.

[0030] A "beam transport vehicle" is a special engineering vehicle used to transport large precast concrete beams at railway and highway bridge construction sites. These bridge components are usually enormous and require the assembly of multiple vehicle body components to meet the transportation needs of large precast concrete beams. Therefore, how to easily and quickly assemble beam transport vehicles is one of the key issues in transporting large precast concrete beams.

[0031] To address the aforementioned problems, this application provides a vehicle body, as shown in the reference... Figure 1 As shown, it includes a drive assembly 200, multiple body assemblies 100, and at least one connecting assembly 300. The body assembly 100 is provided with multiple snap-fit ​​portions 110; combined with Figure 2 As shown, the drive assembly 200 includes a drive motor 210 and a lead screw 220. The drive motor 210 is connected to the lead screw 220, and the drive motor 210 is used to drive the lead screw 220 to rotate; combined with Figure 3As shown, the connecting assembly 300 is disposed between adjacent body components 100. The connecting assembly 300 includes a pressing block 310 and multiple snap-fit ​​members 320. The multiple snap-fit ​​members 320 are spaced apart in a first direction X1. The pressing block 310 is disposed between adjacent snap-fit ​​members 320. In a second direction X2, the pressing block 310 is connected to a lead screw 220. The rotation of the lead screw 220 causes the pressing block 310 to move in the second direction X2. The snap-fit ​​members 320 form an inclined force-bearing surface 321 in the first direction X1, and the pressing block 310 forms an inclined pushing surface 311 in the first direction X1. The pushing surface 311 and the force-bearing surface 321 abut against each other. Through the cooperation of the pushing surface 311 and the force-bearing surface 321, the pressing block 310 causes the snap-fit ​​members 320 to move closer to or further away from the snap-fit ​​part 110 in the first direction X1. The first direction X1 intersects with the second direction X2. This design makes the assembly between adjacent body components 100 more flexible and convenient. The extrusion block 310 is moved by the lead screw 220 in the second direction X2. The interaction of the inclined force-bearing surface 321 and the pushing surface 311 converts the displacement in the second direction X2 into the displacement in the first direction X1, thereby adjusting the position of the locking member 320 in the first direction X1. This allows the locking member 320 to move closer to or further away from the locking part 110 in the first direction X1, thus enabling the locking member 320 to engage and disengage from the locking part 110. This structure reduces the operational complexity of traditional mechanical connection methods, making vehicle assembly more convenient. Due to the modular design, the vehicle body components 100 can be flexibly combined according to actual needs to adapt to the requirements of different transportation tasks. Compared with the fixed structure of traditional beam transport vehicles, this adjustable connection method significantly improves the versatility and ease of operation of the equipment and reduces maintenance costs.

[0032] In some embodiments, refer to Figure 1 As shown, the vehicle body is assembled from multiple independent body components 100, the number of which is determined by the precast concrete beams. The connecting assembly 300 also includes a second housing 360, on which the drive motor 210 is mounted. The snap-fit ​​component 320 and the compression block 310 are located inside the second housing 360, and are protected by being enclosed within the second housing 360.

[0033] Reference Figure 2 As shown, the lead screw 220 adopts a reverse thread structure. The drive motor 210 can drive the lead screw 220, thereby realizing the opposite movement and back-to-back movement of the extrusion blocks 310 through the reverse thread structure. The snap-fit ​​members 320 in the connecting assembly 300 are distributed in an array and can be arranged at intervals along the first direction X1 and the second direction X2. The specific number is determined according to the connection strength of the body assembly 100.

[0034] In some embodiments, refer to Figure 2As shown, the snap-fit ​​members 320 are spaced apart in the first direction X1, and both ends of each snap-fit ​​member 320 can snap into the snap-fit ​​portion 110. If there are two snap-fit ​​members 320 spaced apart in the first direction X1, then each body assembly 100 has two snap-fit ​​portions 110 in the first direction X1, both of which snap into the ends of the snap-fit ​​members 320.

[0035] In some embodiments, refer to Figure 3 As shown, the engaging portion 110 and the engaging member 320 can be engaged using a wedge-shaped block locking structure, a hydraulic locking pin and latching mechanism, etc. The wedge-shaped block locking structure involves setting both the end of the engaging member 320 and the engaging portion 110 of the body assembly 100 as wedge-shaped blocks, with the corresponding wedge-shaped blocks engaging with each other. The hydraulic locking pin and latching mechanism involves providing pin holes on the body assembly 100, with the engaging member 320 inserted into the pin holes and secured by a latching pin to achieve the engagement. Other engagement methods can also be used between the engaging portion 110 and the engaging member 320 to achieve the engagement between them.

[0036] In the embodiments of this application, reference is made to Figure 3 As shown, the snap-fit ​​part 110 is configured as a first wedge block 111, and the snap-fit ​​member 320 includes a crossbeam 326 and a second wedge block 327. The second wedge block 327 is disposed at the end of the crossbeam 326. The first wedge block 111 and the second wedge block 327 are correspondingly disposed, and the first wedge block 111 and the second wedge block 327 snap-fit ​​each other.

[0037] In some embodiments, the first direction X1 is the vertical direction of the vehicle body, the second direction X2 is the left-right direction of the vehicle body, and the third direction X3 is the front-back direction of the vehicle body. The front-back direction of the vehicle body is also the length direction of the vehicle body, and the left-right direction of the vehicle body is also the width direction of the vehicle body.

[0038] In some embodiments, refer to Figure 4As shown, the pressing block 310 has two pushing surfaces 311 in the first direction X1, and the distance between the two pushing surfaces 311 gradually increases from the outside to the inside in the second direction X2. Adjacent latching members 320 in the first direction X1 each have a force-bearing surface 321, and the distance between the two force-bearing surfaces 321 gradually increases from the outside to the inside in the second direction X2. By gradually increasing the distance between the pushing surfaces 311 from the outside to the inside, the pressing block 310 forms a trapezoidal structure. The distance between the force-bearing surfaces 321 gradually increases from the outside to the inside, forming a trapezoidal hole structure between adjacent force-bearing surfaces 321. When the pressing block 310 moves outward in the second direction X2, the pushing surfaces 311 apply a pushing force to the force-bearing surfaces 321, causing the distance between adjacent latching members 320 to gradually increase and move closer to the latching portion 110. As the pressing block 310 moves inward in the second direction X2, the distance between adjacent pushing surfaces 311 gradually decreases. At least one latching member 320 moves closer to another latching member 320 under the influence of gravity, causing the distance between adjacent latching members 320 to gradually decrease and move away from the latching portion 110. This technical feature can be implemented in various ways. For example, the pressing block 310 can be designed with a wedge shape or other tapered shape, and the material can be a high-strength alloy or composite material to ensure sufficient rigidity and durability. The force-bearing surface 321 of the latching member 320 can adopt a similar design concept, and precision machining can be used to ensure that its distance change in the second direction X2 meets the requirements. During implementation, computer-aided design technology can be used for modeling and verification to ensure precise fit of the dimensions of each part.

[0039] In some embodiments, combined with Figure 3 and Figure 4 As shown, when the pressing blocks 310 move towards each other in the second direction X2, the force-bearing surface 321 and the pushing surface 311 slide relative to each other, causing the locking members 320 to move closer to each other in the first direction X1, away from the locking portion 110; when the pressing blocks 310 move away from each other in the second direction X2, the force-bearing surface 321 and the pushing surface 311 slide relative to each other, causing the locking members 320 to move away from each other in the first direction X1, closer to the locking portion 110. This design allows the locking members 320 to be flexibly released or fixed, improving the convenience of installation and maintenance. At the same time, when fixing is required, the locking members 320 move closer to the locking portion 110, ensuring a stable connection. This structure not only improves operational flexibility but also ensures the reliability of the connection.

[0040] In some embodiments, the second direction X2 can be the width direction of the vehicle body or other specific directions. When the pressing blocks 310 move towards each other along this direction, the relative sliding between the force-bearing surface 321 and the pushing surface 311 causes the latching members 320 to approach each other in another direction (the first direction X1), thereby moving away from the latching portion 110. This design allows the latching members 320 to be released or repositioned, facilitating installation and removal. Conversely, when the pressing blocks 310 move in the opposite direction along the second direction X2, the sliding of the force-bearing surface 321 and the pushing surface 311 causes the latching members 320 to disperse in the first direction X1 and approach the latching portion 110, achieving connection between the two or enhancing the tightness of the connection between them.

[0041] In some embodiments, refer to Figure 2 As shown, at least one connecting component 300 includes a first connecting component 301 and a second connecting component 302, which are spaced apart in the second direction X2. The pressing blocks 310 of the first connecting component 301 and the second connecting component 302 are respectively connected to a lead screw 220 in the second direction X2. Rotation of the lead screw 220 causes the pressing blocks 310 to move towards or away from each other in the second direction X2, thereby causing the locking members 320 of the first connecting component 301 and the second connecting component 302 to move closer to or further away from the corresponding locking portions 110 in the first direction X1. The main advantages of this technical solution are: First, the spaced-apart first connecting component 301 and second connecting component 302 in the second direction X2 make the entire mechanical structure more stable and reliable. Second, the design of the lead screw 220 rotating to move the pressing blocks 310 ensures the accuracy and synchronization of the system operation. Finally, the ability of the snap-fit ​​connector 320 to be adjusted closer to or further away in the first direction X1 provides greater flexibility and adaptability, meeting diverse installation and usage requirements. This design not only improves the overall performance of the mechanical system but also simplifies the installation process and effectively saves space.

[0042] In some embodiments, refer to Figure 2 As shown, the first connecting component 301 and the second connecting component 302 are arranged along the second direction X2 and are spaced apart from each other. Each connecting component 300 is equipped with a pressing block 310, which is connected to the lead screw 220. When the lead screw 220 rotates, it drives the pressing blocks 310 to move in the second direction X2, and this movement can be in opposite directions. With this design, the snap-fit ​​pieces 320 on the first connecting component 301 and the second connecting component 302 can be adjusted in position in the first direction X1, thereby moving closer to or further away from the corresponding snap-fit ​​part 110.

[0043] In some embodiments, refer to Figure 2 As shown, the snap-fit ​​component 320 includes a first snap-fit ​​component 322, a second snap-fit ​​component 323, a third snap-fit ​​component 324, and a fourth snap-fit ​​component 325, and the compression block 310 includes a first compression block 312 and a second compression block 313; the first snap-fit ​​component 322, the second snap-fit ​​component 323, and the first compression block 312 are configured as a first connecting assembly 301; the third snap-fit ​​component 324, the fourth snap-fit ​​component 325, and the second compression block 313 are configured as a second connecting assembly 302; wherein, the first compression block 312 and the second compression block 313 are spaced apart in the second direction X2, the first compression block 312 is located between the first snap-fit ​​component 322 and the second snap-fit ​​component 323 in the first direction X1, and the second compression block 313 is located between the third snap-fit ​​component 324 and the fourth snap-fit ​​component 325 in the first direction X1. By rationally distributing the snap-fit ​​component 320 and the compression block 310 into two independent connecting assemblies 300, the overall stability and durability of the vehicle body structure are enhanced. The first connecting component 301 and the second connecting component 302 are responsible for different stress-bearing areas, avoiding stress concentration and improving safety. When the vehicle is subjected to impact or vibration, this layered arrangement can effectively absorb energy and reduce the possibility of structural deformation and damage.

[0044] In some embodiments, refer to Figure 2 As shown, the vehicle body design incorporates multiple connecting components 300 to enhance structural stability. Four snap-fit ​​members 320 and two compression blocks 310 work together to form a coordinated connection system. The first connecting component 301 consists of a first snap-fit ​​member 322, a second snap-fit ​​member 323, and a first compression block 310 in between. The second connecting component 302 consists of a third snap-fit ​​member 324, a fourth snap-fit ​​member 325, and a second compression block 310 in between. This configuration ensures that the vehicle body component 100 has sufficient support in the length direction (third direction X3) and width direction (second direction X2) or height direction (first direction X1). In practice, the snap-fit ​​members 320 can be made of high-strength, lightweight materials such as aluminum alloy or carbon fiber composite materials. The compression blocks 310 are used to absorb and disperse stress from different directions, and are typically made of metal materials with good plasticity and strength, and are heat-treated to improve their load-bearing capacity.

[0045] In some embodiments, refer to Figure 2As shown, the connecting assembly 300 also includes a first guide rod 330 and a second guide rod 340. The first guide rod 330 passes through the adjacent snap-fit ​​member 320 in a first direction X1, and the second guide rod 340 passes through the compression block 310 in a second direction X2. This structure increases the stability of the connecting assembly 300 and improves the overall strength and durability of the vehicle body. The first guide rod 330, positioned in the first direction X1, guides the connecting member 410, while the second guide rod 340, designed in the second direction X2, guides and bears the weight of the compression block 310. This design not only improves the stability of the connecting assembly 300 but also enhances the safety performance of the vehicle body. This design can be implemented using various materials and installation methods, such as using high-strength alloys to manufacture the guide rods and precision machining to ensure accurate fit with the snap-fit ​​member 320 and the compression block 310.

[0046] In some embodiments, refer to Figure 2 As shown, the connecting assembly 300 also includes an elastic element 350, which is sleeved on the first guide rod 330. On one hand, when the latching members 320 move towards each other, the addition of the elastic element 350 to the connecting assembly 300 allows for a pulling force acting on the latching members 320, causing them to gradually detach from the latching portion 110. Since the latching members 320 and the latching portion 110 may attract each other due to capillary forces during long-term use, making it difficult for the latching members 320 to detach under gravity, the pulling force of the elastic element 350 promotes this detachment. On the other hand, the elastic element 350 sleeved on the first guide rod 330 improves the cushioning performance of the vehicle body connection. This design effectively absorbs vibration energy during vehicle operation.

[0047] In some embodiments, refer to Figure 2 As shown, the elastic element 350 is a component capable of storing and releasing energy. The elastic element 350 can be made of spring, rubber, or other elastic materials. The elastic element 350 is fitted onto the first guide rod 330. The elastic element 350 can be directly fitted onto the first guide rod 330 and positioned using appropriate fixing devices. Alternatively, the elastic element 350 can be combined with other components of the guide rod to form an integrated elastic system. In specific implementations, different specifications and types of elastic elements 350 can be selected according to actual needs to adapt to different usage environments and requirements.

[0048] In some embodiments, refer to Figure 5 As shown, the body assembly 100 includes a first housing 120 forming a receiving cavity 121; the body also includes a reinforcing assembly 400 disposed in the receiving cavity 121. (Refer to...) Figure 6As shown, the reinforcing component 400 includes multiple connectors 410 and multiple support frames 420. The support frames 420 are spaced apart along a third direction X3. The connectors 410 are located at least on opposite sides of the support frames 420. Each connector 410 has multiple slots 411 along the third direction X3. The connectors 410 engage with the support frames 420 through these slots 411. The third direction X3, the second direction X2, and the first direction X1 are perpendicular to each other. By spaced the support frames 420 along the third direction X3, pressure from different parts of the body component 100 can be effectively distributed, thereby improving the overall strength and rigidity of the body. The engagement of the connectors 410 with the support frames 420 through the slots 411 not only makes installation simpler and faster but also ensures a stable connection between the components, further enhancing structural stability. This design also features high adjustability and modularity. Because the connectors 410 have multiple slots 411 distributed along the third direction X3, different engagement positions can be selected according to actual needs, allowing for flexible adjustment and optimization. In summary, this body design, through its rational spatial layout and efficient connection methods, not only improves structural strength and stability but also simplifies the installation process and enhances maintenance convenience.

[0049] In some embodiments, combined with Figure 5 and Figure 6 As shown, the first housing 120 is a major structural component of the vehicle body, forming a closed space, namely, a receiving cavity 121. This receiving cavity 121 can accommodate various equipment or components. A reinforcing assembly 400 is located inside this receiving cavity 121. The reinforcing assembly 400 increases the structural strength of the first housing 120 while also reducing the weight of the vehicle body assembly 100. The reinforcing assembly 400 consists of multiple connectors 410 and support frames 420. The support frames 420 are arranged along a third direction X3 and maintain a certain distance from each other. This design helps to distribute forces and improve the overall structural rigidity. The connectors 410 can be installed on opposite sides of the support frames 420 or on multiple sides of the support frames 420, but when there are only two connectors 410, it is best to install them on opposite sides to improve the structural stability of the reinforcing assembly 400 and ensure that the various support frames 420 can be securely joined together. Each connector 410 has multiple slots 411 distributed along a third direction X3. Through these slots 411, the connector 410 can be quickly and reliably engaged with the support frame 420 to form a stable connection structure.

[0050] In some embodiments, refer to Figure 7As shown, the vehicle body also includes a composite component 500, which is disposed on the body component 100. The composite component 500 includes a wear-resistant layer 510, a fiber layer 520, and an anti-corrosion layer 530 stacked from the direction close to the body component 100 to the direction away from the body component 100. This design significantly improves the durability and corrosion resistance of the body material, enhancing structural strength and safety. The wear-resistant layer 510 reduces wear between metal parts, extending service life; the fiber layer 520 increases the friction between the wear-resistant layer 510 and the anti-corrosion layer 530; and the anti-corrosion layer 530 effectively prevents rust and other chemical corrosion. These improvements allow the body to maintain good condition in various environments, reducing maintenance frequency and improving the overall performance of the vehicle.

[0051] In some embodiments, refer to Figure 7 As shown, the composite component 500 is a multi-layered structure installed on the body assembly 100 to support the precast concrete beams. The wear-resistant layer 510 is located on the innermost side, in close contact with the body assembly 100, to reduce friction and wear; the fiber layer 520 is in the middle position, increasing the friction between the wear-resistant layer 510 and the anti-corrosion layer 530; the anti-corrosion layer 530 is on the outer side, preventing corrosive factors in the environment from damaging the body.

[0052] This application also provides a vehicle comprising a body. By adopting the above-described body design, the overall performance of the vehicle is significantly improved. The modular or unibody body structure can be flexibly adjusted according to different application scenarios to meet diverse needs, while ensuring the vehicle's stability and reliability. These improvements give the vehicle significant advantages in both safety and functionality.

[0053] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
