Description

Technical Field

[0001] This application relates to the field of trailer technology, and more specifically, to a cargo box door, a cargo box structure, and a trailer. Background Technology

[0002] In today's domestic highway logistics market, stake trailers are among the most common vehicle types due to their wide applicability and low weight. With the rapid penetration of the new energy commercial vehicle market, competition among products in core elements such as driving range and functional configurations is becoming increasingly fierce. However, while larger power batteries and richer configurations meet users' demands for improved range and experience, they also increase the overall vehicle weight, reducing loading capacity and directly leading to a decrease in transport capacity. Therefore, lightweighting has become one of the core requirements for new energy commercial vehicles.

[0003] Traditional lightweight structural engineering has undergone multiple rounds of market and technological iterations, and its technological potential has been almost fully explored. Magnesium alloys, as a new structural material, possess excellent mechanical properties, low density, and abundant reserves in my country, along with an advanced and comprehensive upstream industry, making them a promising candidate for lightweight transportation equipment and offering a favorable industrialization environment. While magnesium alloys can reduce the overall weight of vehicles as a new material for body structures, they suffer from insufficient weldability stability. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Please refer to Figure 2 and Figure 5 This embodiment provides a van door 120, including an outer frame 121 and a grille 122 and corrugations 123 disposed within the outer frame 121. The grille 122 is disposed above the corrugations 123. The grille 122 includes a horizontal bar 1221 and a vertical bar 1222. The horizontal bar 1221 is provided with a plug-in portion 1221a, and the vertical bar 1222 is inserted into the plug-in portion 1221a. The plug-in portions of the horizontal bar 1221 and the vertical bar 1222 are welded together.

[0030] Specifically, when assembling the body door 120 of this application, corrugated 123 and grille 122 are installed inside the outer frame 121. The grille 122 is installed above the corrugated 123. When installing the grille 122, the longitudinal bar 1222 is inserted into the insertion part 1221a of the transverse bar 1221, and the insertion points of the transverse bar 1221 and the longitudinal bar 1222 are welded. At this time, the insertion points of the transverse bar 1221 and the longitudinal bar 1222 are limited and fixed by the insertion part 1221a, which can reduce the support strength of the welded joint of the transverse bar 1221 and the longitudinal bar 1222. Welding is performed at the connection point based on the insertion. Thus, the insufficient geometric stability of magnesium alloy welding is compensated for, and the support stability of the body door 120 is improved.

[0031] The vehicle body door 120 provided in this application includes an outer peripheral frame 121 and a grille 122 and corrugations 123 disposed within the outer peripheral frame 121. The grille 122 is disposed above the corrugations 123 and includes horizontal bars 1221 and vertical bars 1222. The horizontal bars 1221 are provided with insertion portions 1221a, and the vertical bars 1222 are inserted into the insertion portions 1221a. The insertion points of the horizontal bars 1221 and the vertical bars 1222 are welded together, and welding is performed at the connection points based on the insertion. This compensates for the insufficient geometric stability of magnesium alloy welding and improves the supporting stability of the vehicle body door 120.

[0032] In one possible embodiment of this application, such as Figure 2 and Figure 5 As shown, the insertion part 1221a includes a plurality of mounting holes provided on the crossbar 1221, and the longitudinal bar 1222 is inserted into the mounting holes.

[0033] Specifically, multiple mounting holes are spaced apart on the crossbar 1221, and the longitudinal bar 1222 is inserted into the mounting holes. The longitudinal bar 1222 provides longitudinal support for the cargo box door 120, and the mounting holes limit and fix the longitudinal bar 1222. This reduces the stress on the welding point of the crossbar 1221 and the longitudinal bar 1222, improves the connection stability of the crossbar 1221 and the longitudinal bar 1222, thereby improving the support strength of the grille 122 and the stability of the cargo box door 120.

[0034] In one possible embodiment of this application, such as Figure 2 and Figure 5As shown, the outer frame 121 includes a first horizontal frame 1211, a first vertical frame 1212, a second horizontal frame 1213, and a second vertical frame 1214 arranged sequentially. The first horizontal frame 1211 has a first connecting part and a second connecting part at both ends. The first vertical frame 1212 has a third connecting part and a fourth connecting part at both ends. The second horizontal frame 1213 has a fifth connecting part and a sixth connecting part at both ends. The second vertical frame 1214 has a seventh connecting part and an eighth connecting part at both ends. The first connecting part and the third connecting part are connected by a first connecting piece 1215, the second connecting part and the seventh connecting part are connected by a second connecting piece 1216, the fifth connecting part and the fourth connecting part are connected by a third connecting piece 1217, and the sixth connecting part and the eighth connecting part are connected by a fourth connecting piece 1218.

[0035] Specifically, the first connecting member 1215, the second connecting member 1216, the third connecting member 1217, and the fourth connecting member 1218 are all vertically arranged two connecting rods. The first connecting member 1215 is inserted into the first connecting part and the third connecting part, respectively; the second connecting member 1216 is inserted into the second connecting part and the seventh connecting part, respectively; the third connecting member 1217 is inserted into the fifth connecting part and the fourth connecting part, respectively; and the fourth connecting member 1218 is inserted into the sixth connecting part and the eighth connecting part, respectively. The first connecting member 1215 connects the first connecting part and the third connecting part; the second connecting member 1216 connects the second connecting part and the seventh connecting part; the third connecting member 1217 connects the fifth connecting part and the fourth connecting part; and the fourth connecting member 1218 connects the sixth connecting part. The outer peripheral frame 121 is assembled by welding the first connecting member 1215 to the connection between the first and third connecting members, welding the second connecting member 1216 to the connection between the second and seventh connecting members, welding the third connecting member 1217 to the connection between the fifth and fourth connecting members, and welding the fourth connecting member 1218 to the connection between the sixth and eighth connecting members. Compared with the direct welding of the first horizontal frame 1211, the first vertical frame 1212, the second horizontal frame 1213, and the second vertical frame 1214, the assembly method of the first horizontal frame 1211, the first vertical frame 1212, the second horizontal frame 1213, and the second vertical frame 1214 in this application can improve the overall stability of the outer peripheral frame 121.

[0036] In one possible embodiment of this application, such as Figure 2 and Figure 4As shown, the first connecting part consists of multiple first through holes on the first horizontal frame 1211, the second connecting part consists of multiple second through holes on the first horizontal frame 1211, the third connecting part consists of multiple third through holes on the first vertical frame 1212, the fourth connecting part consists of multiple fourth through holes on the first vertical frame 1212, the fifth connecting part consists of multiple fifth through holes on the second horizontal frame 1213, the sixth connecting part consists of multiple sixth through holes on the second horizontal frame 1213, the seventh connecting part consists of multiple seventh through holes on the second vertical frame 1214, and the eighth connecting part consists of multiple eighth through holes on the second vertical frame 1214.

[0037] Specifically, the first connector 1215 is welded to the connection between the first and third through holes using welding rods, thereby ensuring a stable connection between the first horizontal frame 1211, the first vertical frame 1212, and the first connector 1215. The second connector 1216 is welded to the connection between the second and seventh through holes using welding rods, thereby ensuring a stable connection between the first horizontal frame 1211, the second vertical frame 1214, and the second connector 1216. The third connector 1217 is welded to the connection between the fifth and fourth through holes using welding rods, thereby ensuring a stable connection between the second horizontal frame 1213, the first vertical frame 1212, and the third connector 1217. The fourth connector 1218 is welded to the connection between the sixth and eighth through holes using welding rods, thereby ensuring a stable connection between the second horizontal frame 1213, the second vertical frame 1214, and the fourth connector 1218, thus completing the assembly of the outer peripheral frame 121. A plug welding process is used to fill the perforated holes with welding rods for welding, achieving a stable connection between the connectors, crossbars, and longitudinal bars. Compared to other conventional connection methods, such as simple bolt connections or riveting, this connection method significantly enhances the overall structural strength of the outer frame 121. When subjected to external forces, such as pressure, tension, or impact, the components are less prone to displacement or loosening, thus ensuring the stability of the frame structure. This allows it to better meet the requirements of various complex working conditions, effectively extending the service life of the frame and reducing maintenance costs and safety risks caused by structural loosening or damage. This improves the overall strength of the outer frame 121.

[0038] In one possible embodiment of this application, such as Figure 2 and Figure 4 As shown, a crossbeam 124 is provided between the grille 122 and the corrugated 123.

[0039] Furthermore, a first reinforcing rod 125 is also provided between the crossbeam 124 and the first longitudinal frame 1212.

[0040] Furthermore, a second reinforcing rod 126 is provided between the crossbeam 124 and the second longitudinal frame 1214.

[0041] Specifically, when using the body door 120 of this application, the first horizontal frame 1211 and the first vertical frame 1212 are connected by the first connector 1215 passing through the first and third through holes; the first horizontal frame 1211 and the second vertical frame 1214 are connected by the second connector 1216 passing through the second and seventh through holes; the second horizontal frame 1213 and the first vertical frame 1212 are connected by the third connector 1217 passing through the fifth and fourth through holes; and the second horizontal frame 1213 and the second vertical frame 1214 are connected by the fourth connector 1218 passing through the sixth and eighth through holes, thus completing the assembly of the outer peripheral frame 121. The first connector 1215 is then welded to the connection point of the first and third through holes. The second connector 1216 is welded to the connection between the second and seventh through holes, the third connector 1217 is welded to the connection between the fifth and fourth through holes, and the fourth connector 1218 is welded to the connection between the sixth and eighth through holes to complete the assembly of the outer frame 121. Corrugated 123 and grille 122 are provided inside the outer frame 121. Corrugated 123 is located at the bottom of grille 122. A crossbeam 124 is provided between grille 122 and corrugated 123. A first reinforcing rod 125 is provided between the crossbeam 124 and the first longitudinal frame 1212. A second reinforcing rod 126 is provided between the crossbeam 124 and the second longitudinal frame 1214 to strengthen the overall strength of the body door 120.

[0042] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a box structure 100 is provided, including a box frame 110 and a box door 120. The box frame 110 includes a top beam 111 and a plurality of columns 112 connecting the top beam 111 and the vehicle chassis. The box door 120 is disposed between two adjacent columns 112.

[0043] Furthermore, the column 112 has a rectangular cross-section, and a reinforcing rib 1121 is provided inside the column 112, and multiple reinforcing ribs 1121 are provided inside the column 112.

[0044] Specifically, a reinforcing rib 1121 is provided inside the column 112. The reinforcing rib 1121 is parallel to the short side of the rectangular column 112 to improve the support strength of the column 112. When assembling the box structure 100 of this application, the top beam 111 and the vehicle chassis are connected through the column 112 to install the box frame 110 on the vehicle chassis. Then, the box door 120 is installed between two adjacent columns 112 to complete the installation of the box structure 100.

[0045] Furthermore, the reinforcing ribs divide the column into multiple slots, and the top beam 111 and the chassis are provided with protrusions that match the slots. The reinforcing ribs improve the connection stability of the body frame 110.
