[0040] Road transport is a common mode of transportation with the advantages of fast speed, high reliability and high maneuverability. In actual transportation, there are often some long but light goods that need to be transported, such as some foam products. If the weight is used to select the carriage, the goods cannot be completely placed in the carriage. If the length is used to select the carriage, it usually cannot reach the vehicle's load capacity, resulting in a waste of resources.

[0041] Accordingly, this embodiment provides an expanded compartment.

[0042] like Figures 1 to 7As shown, the expansion compartment 1 provided in this embodiment includes a base module 10, an expansion module 20 and a rear panel assembly 30. The base module 10 includes a bottom panel 11, two side panels 12, a back panel 13 and a plurality of first sliding assemblies 14. The bottom panel 11 is used to connect the vehicle. The two side panels 12 are respectively arranged on opposite sides of the bottom panel 11. The back panel 13 is arranged on one side of the bottom panel 11 and is located between the two side panels 12. The plurality of first sliding assemblies 14 are arranged in parallel and at equal intervals on the bottom panel 11, and a receiving cavity 15 is formed between two adjacent first sliding assemblies 14. The expansion module 20 includes a baffle 21 and a plurality of second sliding assemblies 22. The baffle 21 is arranged parallel to the back panel 13, and the plurality of second sliding assemblies 22 are arranged in parallel and at equal intervals on the baffle. The plate 21 is close to one side of the back plate 13, and the second sliding assembly 22 is slidably arranged in the accommodating cavity 15 in a one-to-one correspondence. The first sliding assembly 14 and the second sliding assembly 22 are both used to support the goods; a limiting assembly is arranged between the first sliding assembly 14 and the second sliding assembly 22, and the limiting assembly is used to limit the relative position of the base module 10 and the expansion module 20; the rear plate assembly 30 includes a rear plate 31 and a fixing structure. The rear plate 31 is rotatably arranged on the bottom plate 11, and the rear plate 31 is located on the side of the baffle 21 away from the back plate 13. The rear plate 31 has an open state and a closed state. The fixing structure is used to adjust the rear plate 31 to be in an open state or a closed state. When the rear plate 31 is in the open state, the rear plate 31 is used to support the expansion module 20. Specifically, in this embodiment, the back panel 13, two side panels 12, baffle 21, first sliding assembly 14, and second sliding assembly 22 collectively form a storage space for accommodating cargo. Multiple first sliding assemblies 14 are arranged parallel and equidistantly on the bottom panel 11. Adjacent first sliding assemblies 14 form a storage cavity 15, and the second sliding assembly 22 can slide within the storage cavity 15. To expand the storage space of the vehicle compartment, the baffle 21 is pulled, which drives the second sliding assembly 22 to slide out of the storage cavity 15, thereby increasing the length of the storage space and increasing the volume of the expanded vehicle compartment 1. When the rear panel assembly 30 is closed, the expansion module 20 is fixed between the rear panel assembly 30 and the back panel 13, preventing the expansion module 20 from falling when the vehicle is empty. When the rear panel assembly 30 is open, it is flush with the bottom panel 11, providing support for the pulled-out expansion module 20 and preventing it from falling out, thereby ensuring safety during use. The limiting assembly can limit the relative position of the base module 10 and the extension module 20 to ensure that the extension module 20 does not move relative to the base module 10 when carrying goods, thereby preventing the baffle 21 from colliding with the internal goods.

[0043] Furthermore, a guide rail is provided on the side wall of the accommodating cavity 15 and one of the second sliding components 22, and a slide groove is provided on the other side wall of the accommodating cavity 15 and the second sliding component 22. The guide rail and the slide groove can slide relative to each other, and the limiting component includes a first limiting portion and a second limiting portion. The guide rail is provided with the first limiting portion, and the slide groove is provided with the second limiting portion. The first limiting portion and the second limiting portion are used to limit the positions of the first sliding component 14 and the second sliding component 22. Specifically, in this embodiment, the guide rail is provided on the first sliding component 14, and the slide groove is provided on the second sliding component 22. In other embodiments, the guide rail can also be provided on the second sliding component 22, and the slide groove is provided on the first sliding component 14. This arrangement can ensure that the second sliding component 22 can slide smoothly along the accommodating cavity 15, avoid the second sliding component 22 and the accommodating cavity 15 from getting stuck, and ensure ease of use.

[0044] Furthermore, the guide rails include a first guide rail 151 and a second guide rail 152, and the chutes include a first chute 221 and a second chute 222. The first guide rail 151 slides relative to the first chute 221, and the second guide rail 152 slides relative to the second chute 222. Specifically, in this embodiment, two guide rails and two chutes are provided, and the two guide rails can slide relative to the two chutes in a one-to-one correspondence. This can make the support between the first sliding assembly 14 and the second sliding assembly 22 more stable, further ensuring the loading performance of the expansion compartment 1 and preventing collapse during loading.

[0045] Furthermore, the first guide rail 151 in one accommodating cavity 15 is integrally formed with the second guide rail 152 in the adjacent accommodating cavity 15. Specifically, in this embodiment, the first guide rail 151 in one accommodating cavity 15 and the second guide rail 152 in the adjacent accommodating cavity 15 are integrally formed and form a C-shape as a whole. The first sliding assembly 14 also includes a vertical plate. The space between the two adjacent vertical plates is the accommodating cavity 15. One end of the vertical plate is connected to the bottom plate 11, and the other end is connected to the middle of the C-shape. The C-shape opens downward, so that the two sides of the C-shape are located in different accommodating cavities 15, respectively. This ensures that the overall strength is high, can provide sufficient support for the goods, and ensure the safety of the goods.

[0046] Furthermore, the first slide groove 221 and the second slide groove 222 are located in the same first sliding assembly 14 or the same second sliding assembly 22. Specifically, in this embodiment, the second sliding assembly 22 is provided with an upward protrusion, preferably, the protrusion is at the same height as the C-shaped portion of the first sliding assembly 14, and the two sides of the protrusion extend downward and are folded twice to form the first slide groove 221 and the second slide groove 222, which are used to slide with the first guide rail 151 and the second guide rail 152 in the corresponding accommodating cavity 15. This arrangement ensures that the first guide rail 151 and the second guide rail 152 of the first sliding assembly 14 and the first slide groove 221 and the second slide groove 222 of the second sliding assembly 22 are exactly staggered, further improving the supporting performance of the first sliding assembly 14 and the second sliding assembly 22 for cargo.

[0047] Furthermore, the first limiting portion is a limiting groove 1511, and the second limiting portion is a roller 2211. The guide rail can slide along the roller 2211, and the roller 2211 can engage with the limiting groove 1511. Specifically, in this embodiment, the provision of the roller 2211 can convert the sliding of the guide rail along the guide groove into rolling along the roller 2211, thereby reducing the force required to pull out the expansion module 20 and alleviating the workload of the personnel. In addition, the limiting groove 1511 on the guide rail allows the roller 2211 to be pressed against the limiting groove 1511 after the expansion module 20 is pulled out under the action of its own weight and the cargo in the carriage, ensuring that the relative position between the expansion module 20 and the base module 10 is relatively stable.

[0048] Furthermore, multiple limiting grooves 1511 and rollers 2211 are provided, the multiple limiting grooves 1511 are provided at equal intervals, the multiple rollers 2211 are provided at equal intervals, and the distance between two adjacent limiting grooves 1511 is the same as the distance between two adjacent rollers 2211. Specifically, in this embodiment, one guide rail has three equally spaced limiting grooves 1511, one chute is provided with three equally spaced rollers 2211, and the distance between two adjacent limiting grooves 1511 is equal to the distance between two adjacent rollers 2211. This arrangement enables the expansion module 20 to have three options based on the extended distance of the base module 10. The extended distance of the expansion module 20 can be selected based on the length of the cargo to be placed, which not only increases the flexibility of the expansion compartment 1 but also ensures driving safety.

[0049] Furthermore, the fixing structure comprises a pull rod 321 rotatably mounted on the rear panel 31. The pull rod 321 has a fixing slot. A first fixing bolt 121 and a second fixing bolt 122 are mounted on the side panels 12. The fixing slots can engage with the first fixing bolt 121 and the second fixing bolt 122, respectively, to position the rear panel 31 in an open or closed state. Specifically, in this embodiment, the first fixing bolt 121 and the second fixing bolt 122 are mounted on both side panels 12, and the pull rod 321 is rotatably mounted on both sides of the rear panel 31. This ensures a more stable position of the rear panel 31 and ensures the safety of the cargo.

[0050] Furthermore, the pull rod 321 has a first through hole, and the rear plate 31 is provided with a column 311, which has a second through hole. The first connecting member passes through the first through hole and the second through hole in sequence and is then threadedly connected to a nut to rotatably connect the pull rod 321 to the rear plate 31. Specifically, in this embodiment, the rear plate 31 is a hollow structure surrounded by four columns 311, and the pull rods 321 are rotatably provided on the columns 311 on both sides. The threaded connection facilitates disassembly and maintenance.

[0051] This embodiment also provides a vehicle, which includes a vehicle body and the above-mentioned extended compartment 1, has good adjustability, can meet the transportation needs of goods of various lengths, and has strong flexibility.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
