[0035] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0036] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0037] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] In the related art, gooseneck semi-trailers are widely used in the logistics and transportation industry as an important means of transportation. However, in the existing gooseneck semi-trailer designs, there is a common problem that cannot be ignored, that is, there is a significant height difference between the front neck of the semi-trailer (referring to the part where the traction platform connects the semi-trailer) and the vehicle-mounted plate.

[0039] However, this height difference brings many inconveniences during the assembly and transportation of goods. First, when loading goods, due to the height difference between the front neck and the vehicle-mounted plate, and the limited size of the towing table, it is often necessary to make multiple adjustments to select the best loading position when moving the goods to the towing table. This not only increases the loading time, but may also cause damage to the goods during the adjustment process. Secondly, during transportation, due to the centrifugal force generated by road bumps and turns, the goods may shift or tilt due to unstable fixation, and in severe cases may even cause the goods to slip, posing a threat to transportation safety.

[0040] The present application provides a shelf suitable for gooseneck semi-trailers, which is provided with a rectangular support top frame that can dock and extend the traction platform of the semi-trailer, and a support rod assembly that adjusts the height of the rectangular support top frame to adapt to different semi-trailer front neck heights. The shelf can lengthen the front neck of the gooseneck transport semi-trailer, thereby facilitating the use of cargo distribution by customers, and effectively solving the problem that some goods cannot meet the transportation conditions due to the height difference between the front neck and the rear cargo platform.

[0041] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and implementation methods can be combined with each other if there is no conflict.

[0042] In an exemplary embodiment of the present utility model, a shelf of a gooseneck semi-trailer is provided, such as Figure 1 As shown, Figure 1 1 is a schematic diagram of a shelf suitable for a gooseneck semi-trailer according to an exemplary embodiment. The shelf of the gooseneck semi-trailer includes: a rectangular support top frame 20 and two groups of support rod assemblies 10, etc.

[0043] The top side of the rectangular support frame 20 is formed with a loading platform for docking and extending the traction platform of the semi-trailer. The rectangular support frame 20 has a first side 201 and a second side 202 opposite to each other. The bottom side of the first side 201 and the bottom side of the second side 202 are respectively provided with first limiting card grooves 2011 arranged along the length direction of the corresponding side. At least two first limiting card grooves 2011 are respectively provided on the first side 201 and the second side 202. For example, the first limiting card grooves 2011 can be grooves opened on the first side 201 and the second side 202, which can be engaged with the corresponding support rods; or they can be blocks provided on the lower sides of the first side 201 and the second side 202. The "groove" formed by the cooperation of two adjacent blocks can limit the ends of the first rod 101 and the second rod 102 in the support rod assembly 10.

[0044] Two groups of support rod assemblies 10 are respectively arranged on the first side 201 and the second side 202 of the rectangular support top frame 20, and each group of support rod assemblies 10 includes: a first rod 101, the first end 101A of the first rod is hinged with the first side 201 / the second side 202; a second rod 102, the middle part of the second rod is hinged with the middle part of the first rod 101, and the first end 102A of the second rod is clamped with the first limit clamping groove 2011 of the first side 201 / the first limit clamping groove 2011 of the second side 202. When the shelf is in use, the clamping position of the first end 102A of the second rod and the first limit clamping groove 2011 of the first side 201 / the first limit clamping groove 2011 of the second side 202 can be adjusted to make the shelf support height match the semi-trailer traction platform surface.

[0045] In this exemplary embodiment, the shelf has at least two working positions with different supporting heights. When using the shelf to extend the traction platform surface of a gooseneck semi-trailer, first determine the height difference between the front neck of the semi-trailer and the loading plate. After placing the shelf on the loading plate, adjust the first end 102A of the second rod to the first limit slot 2011 that is adapted to the height difference, so that the loading platform of the rectangular support top frame 20 is flush with the traction platform surface of the semi-trailer, thereby extending the traction platform surface of the semi-trailer and facilitating loading of goods.

[0046] It should be noted that, since the height difference between the front neck of different semi-trailers and the traction platform surface is generally 30cm to 60cm, and in the present embodiment, the number of the first limit slots 2011 is limited, which makes the working position of the shelf include multiple loading platform heights with a preset height difference. Therefore, in the present embodiment, "the loading platform of the rectangular support top frame 20 and the traction platform surface of the semi-trailer are in a flush state" can be understood as the two are approximately flush. If the height difference between the two does not exceed 3cm, it can be considered that the loading platform of the rectangular support top frame 20 and the traction platform surface of the semi-trailer are in a flush state.

[0047] In some exemplary embodiments, considering that the lower part of the shelf is supported only by the ends of the first rod 101 and the second rod 102, its stability may be poor. In order to improve the overall stability of the shelf, the lower structure of the shelf is also optimized in this exemplary embodiment. Figure 2 As shown, the rack also includes: a rectangular support base frame 30, which is used to cooperate with the rectangular support top frame 20 and two groups of support rod assemblies 10 to extend the semi-trailer traction platform surface and form a stable support for the corresponding goods.

[0048] Alternatively, if Figure 2 As shown, in one implementation, the rectangular support bottom frame 30 and the rectangular support top frame 20 are arranged opposite to each other up and down, and the top side of the rectangular support bottom frame 30 is provided with a second limit slot 3011 corresponding to the first limit slot 2011 of the rectangular support top frame 20, wherein the second end 101B of the first rod is engaged with the second limit slot 3011 of the rectangular support bottom frame 30, and the second end 102B of the second rod is hinged with the corresponding side of the rectangular support bottom frame 30. Similar to the design of the first limit slot 2011, the second limit slot 3011 can be understood as a "groove" formed by the cooperation of two adjacent protrusions / blocks arranged on the top side of the rectangular support bottom frame 30, or a groove directly opened on the top side of the rectangular support bottom frame 30.

[0049] When the height of the shelf needs to be adjusted, the rectangular support frame 20 can be lifted, and the intersection angle of the first rod 101 and the second rod 102 can be adjusted so that the first end 102A of the second rod corresponds to the appropriate first limit slot 2011, and the second end 101B of the first rod corresponds to the corresponding second limit slot 3011. Before and after the height of the shelf is adjusted, the distance between the rectangular support frame 20 and the rectangular support bottom frame 30 can be changed while the rectangular support frame 20 and the rectangular support bottom frame 30 are always kept parallel.

[0050] In another alternative embodiment, the shelf also includes: a rectangular support base frame 30, which is arranged opposite to the rectangular support top frame 20 in an upper and lower direction, and the top side of the rectangular support base frame 30 is provided with a second limit slot 3011 corresponding to the first limit slot 2011 of the rectangular support top frame 20; wherein the second end 101B of the first rod is hinged to the corresponding edge of the rectangular support base frame 30, and the second end 102B of the second rod is clamped to the second limit slot 3011 of the rectangular support base frame 30.

[0051] When the height of the shelf needs to be adjusted, the rectangular support frame 20 can be lifted, and the intersection angle of the first rod 101 and the second rod 102 can be adjusted so that the first end 102A of the second rod corresponds to the appropriate first limit slot 2011, and the second end 102B of the second rod corresponds to the corresponding second limit slot 3011. Before and after the height of the shelf is adjusted, the distance between the rectangular support frame 20 and the rectangular support bottom frame 30 can be changed while the rectangular support frame 20 and the rectangular support bottom frame 30 are always kept parallel.

[0052] In some exemplary embodiments, in order to improve the support strength of the two groups of support rod assemblies 10, optionally, connecting rods are staggered or spaced between the corresponding two first rods 101 in the two groups of support rod assemblies 10 to strengthen the connection between the two first rods 101; similarly, connecting rods are staggered or spaced between the corresponding two second rods 102 in the two groups of support rod assemblies 10 to strengthen the connection between the two second rods 102. For example, when the two first rods 101 and the two second rods 102 are respectively strengthened and connected by spaced connecting rods, it can be understood that a structure similar to a "ladder" is formed.

[0053] In some exemplary embodiments, Figure 3 As shown, in order to optimize the material cost and control the weight of the shelf, the rectangular support top frame 20 and the rectangular support bottom frame 30 can adopt a metal square tube structure. Considering the frame strength of the rectangular support top frame 20 and the rectangular support bottom frame 30, corresponding reinforcing beams 40 can be set. Exemplarily, the rectangular support top frame 20 also includes: a third side and a fourth side correspondingly connected to both ends of the first side 201 and the second side 202, and a reinforcing beam 40 spaced between the third side and the fourth side in a direction parallel to the first side 201.

[0054] In some exemplary embodiments, considering that the rectangular support top frame 20 of the shelf is a hollow structure and that some fragile goods need to be supported and protected, the shelf can be further optimized, such as being equipped with a pad of a suitable size. Exemplarily, the shelf also includes: a pad (not shown in the figure), which is detachably arranged on the loading platform for placing goods.

[0055] In some exemplary embodiments, when loading, unloading or transporting goods, in order to avoid relative displacement between the pad and the rectangular support frame 20, the shelf can be optimized by setting a fixing structure. Exemplarily, the shelf also includes: a first fixing portion (not shown in the figure), which is arranged on the rectangular support frame 20; a fastening rope (not shown in the figure), which is connected to the first fixing portion and is used to fix the pad.

[0056] Optionally, the first fixing part is a fixing ring or a fixing hook. After the backing plate is placed on the rectangular support top frame 20, the backing plate is tightened on the fixing ring / fixing hook by tightening ropes.

[0057] In some exemplary embodiments, since the shelf is placed on the vehicle board of the semi-trailer and abuts against the misalignment between the traction platform of the semi-trailer and the vehicle board (i.e., the front neck), it is considered that during the loading and unloading or transportation of goods, the shelf may be placed stably at the front neck due to collision or movement. Therefore, in this embodiment, further improvements are made to the structure of the shelf. Exemplarily, the shelf also includes: a second fixing portion (not shown in the figure), which is arranged on the rectangular support top frame 20 and / or the rectangular support bottom frame 30; an elastic connector (not shown in the figure), one end of which is connected to the second fixing portion, and the other end is formed with a buckle for connecting to the semi-trailer.

[0058] In addition, in order to further prevent the shelf from being placed unstably on the vehicle board, the bottom structure of the shelf can also be optimized. For example, an anti-skid structure is provided on the bottom side of the rectangular support frame 30. Optionally, the anti-skid structure is an anti-skid corrugation formed on the bottom side of the rectangular support frame 30, or an anti-skid pad is provided on the bottom side of the rectangular support frame 30.
