If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0068] Figure 1 This is a schematic diagram of the assembly of a dump truck body in one embodiment of this application; Figure 2 for Figure 1 An exploded view of the dump truck's cargo box in the illustrated embodiment.

[0069] See Figure 1-2The dump truck box 10 provided in one embodiment of this application includes two frames 10, a front panel 20, a rear panel 30, a bottom panel 40, and two side panels 50.

[0070] Two frames 10 are spaced apart along a first direction X. Each frame 10 has a bottom plate connecting part 11 on one side along a second direction Y, and side plate connecting parts 12 on opposite sides along a third direction Z. The bottom plate connecting parts 11 and side plate connecting parts 12 on the same frame 10 extend along the first direction X toward the side closer to the other frame 10. A front plate 20 is connected to one of the frames 10, and a rear plate 30 is connected to the other frame 10. A bottom plate 40 is disposed between the two frames 10. The bottom plate 40 includes a bottom plate body 41 and a bottom plate longitudinal beam 42 extending along the first direction X on the bottom plate body 41. The two ends of the bottom plate longitudinal beam 42 are respectively inserted into the bottom plate connecting parts 11 of the two frames 10. Two side plates 50 are respectively disposed on opposite sides of the bottom plate 40 along the third direction Z, and each side plate 50 is respectively engaged with the side plate connecting parts 12 of the two frames 10 along opposite sides along the first direction X. Among them, the frame 10 is made of metal, and the front plate 20, rear plate 30, bottom plate 40 and two side plates 50 are all made of basalt composite material. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0071] The aforementioned dump truck body 10 utilizes two frames 10 to facilitate the assembly of the front panel 20, rear panel 30, bottom plate 40, and two side panels 50. The side panels 50 are engaged with the side panel connecting parts 12 on the frames 10, and the bottom plate longitudinal beams 42 are inserted into the bottom plate connecting parts 11 on the frames 10, making the connection convenient and easier to assemble, thus improving the reliability of the assembled connection. Furthermore, the metal material of the frames 10 further enhances the reliability of the assembled connection. Since the front panel 20, rear panel 30, bottom plate 40, and two side panels 50 are all made of basalt composite material, the dump truck body 10 is lighter and possesses higher specific strength, stronger corrosion resistance, and higher recyclability.

[0072] Figure 3 for Figure 1 An exploded view of the top plate, front plate, and frame connected to the front plate in the illustrated embodiment.

[0073] To connect the front panel 20 to the frame 10, in some embodiments, in combination with Figure 2-3 As shown, the frame 10 connected to the front plate 20 has a first opening 13 on the side away from the bottom plate 40 along the second direction Y for the front plate 20 to pass through. The inner side of the frame 10 connected to the front plate 20 has a first snap-fit ​​groove 14 communicating with the first opening 13, and the front plate 20 is inserted into the first snap-fit ​​groove 14. In this way, the front plate 20 and the frame 10 can be easily connected.

[0074] Specifically, the front plate 20 is a pultruded basalt profile.

[0075] Figure 4 for Figure 1 A cross-sectional view of the top plate, front plate, and frame connected to the front plate in the illustrated embodiment; Figure 5 for Figure 4 A magnified view of a portion of point B in the illustrated embodiment.

[0076] In some embodiments, such as Figure 4-5 As shown, the dump truck body 10 also includes multiple first reinforcing sleeves 80 and first connecting members 90 corresponding to each of the first reinforcing sleeves 80. The first reinforcing sleeves 80 are disposed in the first snap-fit ​​grooves 14 and pass through the front plate 20 along the first direction X. The first connecting members 90 pass through the frame 10 connected to the front plate 20 and the corresponding first reinforcing sleeves 80 along the first direction X. Thus, by setting the first connecting members 90, the front plate 20 is fixed relative to the frame 10. Furthermore, since the strength at the drilled hole is weak due to fiber interruption after drilling in the basalt composite material, the first reinforcing sleeves 80 are used to improve the structural strength at the drilled hole of the front plate 20 and to improve the connection strength between the front plate 20 and the frame 10.

[0077] Optionally, the first connector 90 may be made of bolts, rivets or other fasteners, and there is no limitation on the type of fasteners used in the first connector 90.

[0078] Specifically, such as Figure 2-3 As shown, the first snap-fit ​​groove 14 extends along the second direction Y on both sides of the frame 10 connected to the front plate 20 along the third direction Z, and extends along the third direction Z on the side of the frame 10 connected to the front plate 20 opposite to the first opening 13 along the second direction Y.

[0079] In some embodiments, such as Figure 3 As shown, the frame 10 is also provided with a top plate connecting part 15. One end of the top plate connecting part 15 is connected to the side of the frame 10 where the first opening 13 is provided, and the other end of the top plate connecting part 15 extends away from the rear plate 30 along the first direction X. The dump truck box 10 also includes a top plate 120, which is inserted into the top plate connecting part 15 along the first direction X.

[0080] Optionally, the top plate 120 is made of pultruded basalt profile.

[0081] Figure 6 for Figure 3 A magnified view of a portion at point A in the illustrated embodiment.

[0082] Specifically, in combination Figure 3 and Figure 6As shown, the inner side of the top plate connecting part 15 is provided with a top plate snap-fit ​​groove 151 extending along the first direction X, and the top plate 120 is inserted into the top plate snap-fit ​​groove 151.

[0083] In the actual assembly process, the steel parts are first welded into a frame 10 that connects to the front plate 20. The frame 10 is provided with a top plate connecting part 15, a bottom plate connecting part 11, and a side plate connecting part 12. Then, the front plate 20 is installed into the first snap-fit ​​groove 14 along the second direction Y, and the front plate 20 is fixed relative to the frame 10 with the first connector 90. Then, the top plate 120 is installed into the top plate snap-fit ​​groove 151 along the first direction X, and the top plate 120 is connected to the top plate connecting part 15 with fasteners.

[0084] Specifically, the side plate connecting part 12 is connected to the side plate 50 by fasteners.

[0085] In some embodiments, the side plate 50 is a pultruded basalt profile.

[0086] It is understandable that a base plate connecting part 11 is provided on the frame 10, and a base plate 40 including a base plate longitudinal beam 42 is provided, with the base plate longitudinal beam 42 inserted into the base plate connecting part 11, so that the base plate 40 can be easily assembled with the frame 10.

[0087] Specifically, the bottom plate longitudinal beam 42 is connected to the bottom plate connection part 11 by fasteners.

[0088] In some embodiments, the base plate 41 and the base plate longitudinal beam 42 are pultruded.

[0089] Figure 7 for Figure 1 The schematic diagram of the base plate in the embodiment shown is viewed from another angle.

[0090] In some embodiments, such as Figure 7 As shown, the longitudinal beam 42 of the base plate has a cavity 42a extending through the longitudinal beam 42 along a first direction X, and a partition plate 43 extending through the cavity 42a along the first direction X. The partition plate 43 divides the cavity 42a into two non-communicating sub-cavities 42a1 arranged along a second direction Y. Thus, by providing the cavity 42a within the longitudinal beam 42, the weight of the longitudinal beam 42 is reduced, and by providing the partition plate 43 within the cavity 42a, the structural strength of the longitudinal beam 42 is improved, thereby enhancing the structural reliability of the base plate 40.

[0091] Figure 8 for Figure 1 A schematic diagram of the base plate in the embodiment shown; Figure 9 for Figure 8 A magnified view of a portion of point C in the illustrated embodiment.

[0092] In some embodiments, such as Figure 8-9As shown, the base plate 41 includes two plates, which are arranged along the third direction Z. Each base plate 41 is provided with at least one base plate longitudinal beam 42, and the base plate connection part 11 (see Figure 2 Each base plate 41 is connected to the longitudinal beam 42 of the base plate in a one-to-one correspondence. Each base plate 41 has a mounting groove 41a on one side facing the other, and the mounting grooves 41a of the two base plates 41 are interconnected. The dump truck body 10 also includes a clamping plate 60 passing through the two mounting grooves 41a along a first direction X. The clamping plate 60 is configured to fix each base plate 40 relative to the other base plate 40 along a third direction Z. Thus, by including two base plates 41, the weight of a single base plate 41 is reduced, facilitating transportation and assembly, and increasing the structural strength of each base plate 41, thereby improving the strength of the base plate 40 and facilitating connection. By providing the clamping plate 60, the two base plates 41 are fixed relative to each other along a third direction Z, thereby connecting to form the base plate 40.

[0093] Specifically, each base plate 41 and the base plate longitudinal beam 42 disposed thereon are integrally pultruded.

[0094] Figure 10 for Figure 8 A magnified view of a portion at point D in the illustrated embodiment; Figure 11 for Figure 1 A schematic diagram of the side plate in the embodiment shown; Figure 12 for Figure 11 A magnified view of a portion of point E in the illustrated embodiment.

[0095] To connect the base plate 40 to the side plate 50, in some embodiments, such as Figure 8 and Figure 10 As shown, the base plate 40 also includes two connecting beams 44 respectively disposed on both sides of the base plate body 41 along the third direction Z. Each connecting beam 44 is connected to the base plate body 41 on one side along the third direction Z, and the connecting beam 44 extends along the first direction X. A groove 44a is formed on the surface of each connecting beam 44 on the side away from the longitudinal beam 42 of the base plate along the second direction Y, extending inward along the second direction Y. The two connecting beams 44 correspond to the two side plates 50 respectively. Figure 11-12 As shown, each side plate 50 has a protrusion 51 protruding along the second direction Y towards the side near the connecting beam 44. Each protrusion 51 extends along the first direction X and fits into a corresponding groove 44a to form a mortise and tenon connection. In this way, the side plate 50 and the bottom plate 40 are assembled together through the cooperation of the protrusion 51 and the groove 44a. Since the connection between the bottom plate 40 and the side plate 50 is a mortise and tenon connection, the connection between the bottom plate 40 and the side plate 50 is a solid structure, avoiding the use of a hollow structure at the connection point, which would make it easily damaged under the impact of goods.

[0096] Specifically, the two connecting beams 44 are respectively connected to the two base plates 41, and each connecting beam 44 is located on the side of the corresponding base plate 41 that is away from the other base plate 41 along the third direction Z.

[0097] In some embodiments, such as Figure 12 As shown, the side plate 50 has a first mating part 52 and a second mating part 53 extending longitudinally along the first direction X on the side near the bottom plate 40 along the second direction Y. One side of the first mating part 52 and one side of the second mating part 53 are connected to the side plate 50, respectively. The other side of the first mating part 52 extends along the third direction Z towards the side near the bottom plate 40 and has a protrusion 51. The other side of the second mating part 53 extends along the second direction Y towards the side near the bottom plate 40. A connecting beam 44 is adapted to connect between the first mating part 52 and the second mating part 53. In this way, the connection between the side plate 50 and the bottom plate 40 forms a mortise and tenon joint and is a solid structure.

[0098] Specifically, the connecting beam 44 and the corresponding second mating part 53 are connected by fasteners.

[0099] Figure 13 for Figure 1 The illustrated embodiment shows an assembly diagram of the base plate, the first crossbeam, and the second crossbeam.

[0100] In some embodiments, such as Figure 13 As shown, the dump truck body 10 also includes first crossbeams 130 spaced apart along a first direction X. Each first crossbeam 130 passes through two connecting beams 44 and all the longitudinal beams 42 of the bottom plate along a third direction Z. The first crossbeams 130 are made of metal. In this way, by setting the first crossbeams 130, the lateral connection strength of the bottom plate 40 is improved.

[0101] In one embodiment, such as Figure 13 As shown, there are six first crossbeams 130. In other embodiments, the number of first crossbeams 130 may be set differently according to usage requirements, and is not limited here.

[0102] Specifically, the first crossbeam 130 and the bottom plate longitudinal beam 42 can be connected by fasteners.

[0103] In some embodiments, combined with Figure 10 and Figure 13As shown, each of the first crossbeams 130 has two connecting beams 44 extending from both ends. The dump truck box 10 also includes a first limiting component corresponding to each of the first crossbeams 130. Each first limiting component includes two first limiting members 140 respectively disposed at both ends of the corresponding first crossbeam 130. Each first limiting member 140 is connected to the corresponding connecting beam 44 along the third direction Z away from the other connecting beam 44. Each first limiting member 140 is inserted along the second direction Y into the part of the first crossbeam 130 that extends out of the connecting beam 44, so as to limit the first crossbeam 130 relative to the connecting beam 44 along the third direction Z.

[0104] In some embodiments, the first crossbeam 130 is connected to the bottom plate longitudinal beam 42 by fasteners.

[0105] In some embodiments, such as Figure 13 As shown, the dump truck body 10 also includes second crossbeams 150 spaced apart along the first direction X. Each second crossbeam 150 passes through all the longitudinal beams 42 of the bottom plate along the third direction Z. Both ends of each second crossbeam 150 are connected to two connecting beams 44, and each second crossbeam 150 is made of basalt composite material. In this way, by setting the second crossbeams 150, the structural strength of the bottom plate 40 is further improved.

[0106] Figure 14 for Figure 1 A partial schematic diagram of the second crossbeam, the second limiting member, and the bottom plate longitudinal beam in the embodiment shown.

[0107] In some embodiments, such as Figure 13-14 As shown, the dump truck body 10 also includes a plurality of second limiting members 160 that are respectively connected to one side of a plurality of bottom plate longitudinal beams 42 along the third direction Z. The second limiting members 160 are inserted into at least two second crossbeams 150 along the first direction X to limit the second crossbeams 150 relative to the bottom plate longitudinal beams 42 along the third direction Z.

[0108] Figure 15 for Figure 1 An assembly diagram of the subframe and rear plate in the illustrated embodiment; Figure 16 for Figure 15 A magnified view of a portion of point F in the illustrated embodiment.

[0109] In some embodiments, such as Figure 2-3 As shown, the dump truck body 10 also includes a sub-frame 110, which is detachably connected to the frame 10 connected to the rear panel 30. Figure 15-16As shown, the sub-frame 110 has a second opening 111 on the side away from the base plate 40 along the second direction Y, through which the rear plate 30 passes. The inner side of the sub-frame 110 has a second locking groove 112 communicating with the second opening 111. The rear plate 30 is inserted into the second locking groove 112 to connect with the frame 10 via the sub-frame 110. The sub-frame 110 is made of metal. This allows the rear plate 30 to be detachably connected to the frame 10 via the sub-frame 110.

[0110] Optionally, the subframe 110 and the frame 10 are connected by cotter pins.

[0111] Specifically, the back plate 30 is a pultruded basalt profile.

[0112] In the actual assembly process, the steel parts are first welded into a sub-frame 110. The sub-frame 110 is provided with a second snap-fit ​​groove 112.
