[0029] As Figures 1-2As shown, it shows a carriage side beam in an embodiment of the utility model, including the connecting piece 1 that symmetrically arranged in the opposite side plate of carriage, every connecting piece 1 is configured as plate structure and integrates inner slot 101, sets up the table part 102, side retaining wall 103 and recessed part 104. Inner slot 101 is formed in the middle part of connecting piece 1 along the vertical extension, its cross section profile is adapted to the outer profile of side plate end, including the parallel groove wall corresponding with the two sides of side plate and the horizontal groove bottom corresponding with the bottom edge of side plate, forms the adaptive space for the end of side plate insertion. The side plate of opposite side of carriage is inserted into the inner slot 101 of corresponding connecting piece 1 from bottom to top respectively, realizes positioning through the fit of groove wall and side plate outer profile, need not additional processing connecting hole.

[0030] Sets up the table part 102 for the platform structure that extends horizontally from the top of inner slot 101 to the outside of connecting piece 1, and the table part 102 of both sides connecting piece 1 is oppositely arranged in the same horizontal plane, and the top surface forms the supporting surface of roof. When the roof is placed, both ends are respectively lapped on the top surface of both sides table part 102, and the horizontal direction is preliminarily positioned by the symmetrically arranged supporting structure. Side retaining wall 103 is the vertical plate piece that extends upward from the outside edge of table part 102, and forms a perpendicular angle with table part 102, and the inner side wall is fitted with the side edge of roof, and the lateral movement of roof in horizontal direction is limited. The connecting place of side retaining wall 103 and table part 102 is inwardly recessed to form recessed part 104, and the opening of the recessed part 104 is towards the supporting surface of table part 102, and the depth and width satisfy the overflow of adhesive when containing the roof. When assembling, first, the adhesive is daubed on the top surface of table part 102 and in recessed part 104, the roof is placed on the supporting surface and abuts against the inner side wall of side retaining wall 103, and the excess adhesive naturally flows into recessed part 104, since the spacing between roof and table part 102 mainly depends on the bolt control, the recessed part 104 can increase the thickness of local adhesive to increase the firmness of bonding, so that the waterproof performance and bonding life between roof and side beam are increased.

[0031] The carriage connecting plate member is connected to the end of the side plate through the inner insertion slot 101 and the matching structure of the end of the side plate, converting the multi-hole alignment operation required by traditional fastening into direct insertion positioning, reducing the alignment steps in the assembly process, and significantly improving the installation efficiency of the side plate and the connecting member 1. The symmetrically arranged erection platform 102 forms a supporting surface at the same horizontal height, providing a stable support foundation for the top plate and avoiding the installation deviation problem of the top plate caused by welding thermal deformation in the prior art. The vertical included angle between the side stop wall 103 and the erection platform 102 is arranged, which forms lateral limiting for the top plate through rigid contact, cooperates with the groove part 104 to accommodate excess glue, realizes the combination of mechanical limiting and glue fixing: the side stop wall 103 limits the lateral displacement of the top plate, and the groove part 104 ensures that the glue fills in a reasonable space, which not only avoids the overflow of glue affecting the appearance, but also enhances the connection strength of the top plate and the erection platform 102 through the glue layer. This structure does not require professional welding equipment or high-precision punching operation, and through the shape matching and position cooperation between the parts, the assembly process of the truck box side plate and the top plate is simplified, the dependence on the technical level of the operator is reduced, and the sealing performance and structural stability of the connection part are improved, effectively solving the problems of large connection difficulty and inconvenient assembly in the prior art.

[0032] In some examples, the inner insertion slot 101 of the connecting member 1 extends vertically in the actual use state. The side of the erection platform 102 close to the inside of the carriage is defined as the inner side, and the side away from the inside of the carriage is defined as the outer side. On the inner side and the outer side of the connecting member 1, the groove wall of the inner insertion slot 101 is respectively recessed inward to form a first groove 105 and a second groove 106. The first groove 105 is relatively high in position, and the second groove 106 is relatively low in position, and the two are arranged in a stepped manner along the vertical direction. When the side plate is inserted into the inner insertion slot 101, the upper part of the inner side wall of the side plate abuts against the outer bottom wall of the first groove 105, and the lower part of the outer side wall of the side plate abuts against the inner bottom wall of the second groove 106, which can provide more accurate vertical positioning during the insertion of the side plate. At the same time, the first groove 105 and the second groove 106 also provide positioning for the bolt. During installation, the bolt passes through the side plate and is screwed into the connecting member 1, and the bolt head can be accommodated in the corresponding groove, so that the connection part is more flat, avoiding the protrusion of the bolt head affecting the installation or use of other parts.

[0033] The inner side and the outer side of the entrance of the inner slot 101 are respectively provided with a first abutting edge 107 and a second abutting edge 108, the vertical position of the first abutting edge 107 is in the same vertical plane as the bottom wall of the first groove 105, and the second abutting edge 108 is in the same vertical plane as the bottom wall of the second groove 106. And the height of the first abutting edge 107 is lower than the height of the second abutting edge 108. This makes the side plate first pass through the first abutting edge 107 and the second abutting edge 108 for preliminary guidance when inserting into the inner slot 101, guiding the side plate to be accurately inserted into the first groove 105 and the second groove 106, further improving the convenience of inserting the side plate. More importantly, the first abutting edge 107 and the second abutting edge 108 provide a welding or gluing point between the connecting piece and the side plate. When welding is performed, the contact part of the abutting edge and the side plate can be welded to enhance the connection strength; if adhesive is used, the contact area of the abutting edge and the side plate can also provide a larger adhesion area for the adhesive, improving the gluing effect. In addition, since the height of the first abutting edge 107 is lower than the height of the second abutting edge 108, when the first abutting edge 107 and the side plate are welded, the outer wall of the connecting piece can block the obvious welding heat marks on the side plate during the welding process, thereby improving the appearance of the overall appearance of the car body.

[0034] The groove walls on the upper and lower sides of the first groove 105 and the second groove 106 are designed as inclined surfaces, and the inclined directions of the inclined surfaces are away from the groove bottoms. When the side plate is inserted into the groove, the inclined surface structure can play a guiding role to reduce the resistance of the side plate insertion, and at the same time after the side plate is inserted, the inclined surface can generate a certain clamping force on the side plate, enhancing the stability of the connection between the side plate and the connecting piece 1.

[0035] The beneficial effects of this design are that through the stepped structure of the first groove 105 and the second groove 106 and the cooperation of the abutting edges, not only the positioning accuracy of the side plate insertion is improved, but also the installation difficulty is reduced. When the side plate is inserted, through the guidance of the abutting edges and the inclined groove walls, the side plate can quickly and accurately abut against the groove, reducing the adjustment time in the installation process. The groove provides positioning and accommodation space for bolt installation, making the connection more stable and flat; the abutting edges provide convenience for welding or gluing, improving the connection strength while optimizing the welding appearance through the height difference. At the same time, the abutment of the groove to the side plate and the clamping action of the inclined groove wall make the connection between the side plate and the connecting piece 1 more stable, improving the stability of the overall structure of the car body.

[0036] In some examples, the included angle between the side wall 103 and the setting table 102 is in the range of 85°-95°. In actual production, the side wall 103 and the setting table 102 are connected by integral molding or welding, etc., to ensure the angle stability between them. When the roof is placed on the setting table 102, the side wall 103 can be perpendicular or approximately perpendicular to the side edge of the roof. Its beneficial effect is that this angle setting can provide stable lateral limiting for the roof. In the process of carriage transportation, it avoids the displacement of the roof due to lateral force, ensures the stability of the connection part between the roof and the side plate, and thus improves the reliability of the overall structure of the carriage, reduces the damage of the connection part caused by the displacement of the roof, etc.

[0037] In some examples, the included angle between the bottom wall of the first groove 105 and the second groove 106 and the inclined side wall thereof is in the range of 70°-140°. In the process of processing the connecting piece 1, it is ensured that the angle range is formed between the bottom wall and the side wall of the groove, and at the same time, the connecting hole 109 is provided on the groove bottom wall and the setting table 102. The connecting hole 109 is used for penetrating the bolt, and is suitable for various bolt connecting pieces with circular, oval or square shapes, and can also be provided without holes, and rivets are selected for fixation. The setting table 102 and the roof can be bolted and riveted through the connecting hole 109, and can also be welded through the intersection between the roof and the side wall 103.

[0038] The beneficial effect of this angle design is that it can provide a position for the fixation of the bolt, facilitate the insertion of the fastener, and also provide a position for accommodating and positioning the bolt head for the first groove 105 and the second groove 106.

[0039] In some examples, the shape of the groove part 104 is a U-shaped groove or a V-shaped groove, and the corresponding groove shape is formed by stamping, milling and other processes in the process of manufacturing the connecting piece 1. The opening of the groove part 104 faces the bearing surface of the setting table 102, and the groove bottom of the groove part 104 and the inner side surface of the side wall 103 are smoothly transitioned, i.e., there is no obvious edge or protrusion between the groove bottom and the inner side surface of the side wall.

[0040] The beneficial effect of this design is that the shape of the U-shaped groove or the V-shaped groove can better accommodate the adhesive overflow when bonding the roof, and compared with other shapes of grooves, it has stronger capacity for accommodating the adhesive and is more convenient for the flow of the adhesive. The smooth transition of the groove bottom of the groove part 104 and the inner side surface of the side wall 103 can avoid the obstruction in the process of adhesive flow, ensure that the adhesive can be smoothly filled to the required position, enhance the connection sealing between the roof and the side wall 103 and the setting table 102, and improve the waterproof and dustproof performance of the connection part.

[0041] The height of the side blocking wall 103 is determined according to the thickness of the top plate, and the height of the side blocking wall 103 is higher than the thickness of the top plate, so that the surface water and sundries of the top plate can be discharged in time during use of the vehicle.

[0042] The beneficial effect of this design is that the side blocking wall 103 is 0-30mm lower than the upper surface of the top plate, so that the top of the vehicle compartment has good drainage performance.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be included in the scope of the claims of the present application.
