Description

Technical Field

[0001] The utility model relates to a door hinge for a light van-type truck and belongs to the technical field of automobile parts. Background Art

[0002] The existing door sealing structure of light van trucks generally adopts two forms: internal sealing and external sealing. The external sealing structure has a part of the compartment sealing strip exposed outside the compartment. The sealing strip is made of rubber material and is prone to aging and failure after long-term exposure. The internal sealing structure is optimized and developed based on the external sealing structure. The internal sealing structure hinge continues to use the original external sealing structure hinge. This hinge structure is heavy and has poor hinge stiffness. The vibration amplitude is large after the door is opened. The existing rear door hinges of vans are mostly flat hinge structures (such as Figure 1 As shown), it has a small thickness, large area, heavy weight and low rigidity. When the rear door of the car is opened, the door vibrates greatly. Summary of the invention

[0004] To solve this technical problem, the utility model provides a door hinge for a van truck, including a hinge assembly and a hexagon socket countersunk screw, the hinge assembly including a hinge seat, a hinge plate, a sleeve and a rivet shaft, the hinge seat is provided with two ear plates on the upper part, the ear plates are provided with coaxial rivet shaft through holes, the hinge plate is a bent structure, one end of which is welded to the sleeve as a whole, and is riveted to the hinge seat using a rivet shaft, and the sleeve can rotate around the rivet shaft after riveting; the hinge seat is installed on the van rear door frame, and the hinge plate is installed on the van rear door panel, and after installation, the van rear door can be opened at any angle within 270°.

[0005] The bottom of the hinge seat is provided with two threaded holes, in which hexagonal flat-end set screws are installed, and the front parts of the two ear plates of the hinge seat are provided with notches.

[0006] The upper plane of the hinge plate is provided with countersunk screw mounting holes for mounting countersunk screws, and notches are opened at both ends of the upper part of the hinge plate to avoid interference with the hinge seat ear plate.

[0007] The hinge seat and the hinge plate are formed by stamping or casting.

[0008] The casing is made of seamless steel pipe.

[0009] The hinge plate and the sleeve are integrally cast.

[0010] Beneficial effects: The hinge of the utility model can open the rear door of a van by 270 degrees, and has the advantages of small and simple structure, convenient processing, light weight, high strength and high rigidity. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 2-Figure 9As shown, the utility model provides a door hinge for a van truck, including a hinge assembly 3 and a hexagon socket countersunk screw 4. The hinge assembly 3 includes a hinge seat 301, a hinge plate 302, a sleeve 303 and a rivet shaft 304. Two ear plates are provided on the upper part of the hinge seat 301, and the sleeve 303 is installed between the two ear plates. A coaxial rivet shaft through hole is provided on the ear plate for installing the rivet shaft 304 and fixing the hinge plate 302 and the sleeve 303; the hinge plate 302 is a bent structure, one end of which is welded to the sleeve 303 as a whole, and is riveted to the hinge seat 301 using the rivet shaft 304. After riveting, the sleeve 303 can easily rotate around the rivet axis 304; the hinge seat 301 is installed on the van rear door frame 1, and the hinge plate 302 is provided with a countersunk hole. The hinge plate 302 is installed on the van rear door panel 2 through the countersunk hole using a hexagon countersunk screw 4. After installation, the screw sinks into the hinge plate, and the outer surface is flat and beautiful; the hinge seat 301 is fixed on the rear door frame, and the hinge plate 302 is fixed on the rear door panel. The hinge plate can rotate 270° around the rivet axis 304. After installation, the rear door of the van can be opened at any angle within 270°, realizing the function of opening the rear door 270°.

[0023] The bottom of the hinge seat 301 is provided with two threaded holes, in which the hexagon socket flat-end set screws 305 are installed, and the front parts of the two ear plates of the hinge seat 301 are provided with notches.

[0024] The upper plane of the hinge plate 302 is provided with a countersunk screw mounting hole 306 for mounting a countersunk screw. Notches are opened at both ends of the upper part of the hinge plate 302 to avoid interference with the ear plate of the hinge seat 301.

[0025] The hinge seat 301 and hinge plate 302 are stamped or cast, with high processing efficiency, high precision and good consistency. When casting is adopted, the rivet shaft 304 can be changed to a bolt connection, the hexagon socket set screw is eliminated, and a round hole is opened on the hinge seat 301 to directly connect with the column, or the hinge seat 301 is welded to the column.

[0026] The sleeve 303 is made of a seamless steel pipe.

[0027] The hinge plate 302 and the sleeve 303 are integrally cast, and the hinge plate 302 can be rotated to any angle less than 270°, so that the rear door can be opened in advance when entering a narrow alley.

[0028] The utility model connects the hinge plate and the rear door of the compartment with a hexagon socket countersunk screw. After installation, the screw sinks into the hinge plate, and the outer surface is flat and beautiful. There is a sleeve between the two ear plates of the hinge seat, and the sleeve can be easily rotated around the rivet axis to achieve the function of the hinge. After the hinge seat and the hinge plate are installed, the rear door of the van can be easily opened and can be opened 270 degrees. When entering a narrow lane, the rear door can be opened in advance. The utility model has the advantages of simple structure, convenient processing, light weight, high strength and high rigidity.

[0029] The above embodiments of the present invention are merely illustrative and not exclusive, and all modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
