DETAILED DESCRIPTION

[0021] The following specific embodiments illustrate the implementation details of the utility model. It should be pointed out that the following embodiments are only for illustrative purposes, and the technical solution can be further improved on the basis of the technical solution disclosed in the claims. If such improvements fully cover the contents disclosed in the claims, they should fall within the protection scope of this patent.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms "left", "right", "front", "rear end", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description. They do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the embodiments of the present invention.

[0023] Embodiment 1:

[0024] A plug-in vehicle roof, as shown in the accompanying drawings, includes a roof and columns; the roof includes a three-sided frame and a cover plate 2 in the middle; the three-sided frame includes left and right side rods 1, and the front ends of the left and right side rods 1 are fixed to a horizontal front rod 12 at the same time. This fixation can be an integral molding, or it can be a welding or plug-in structure. If it is welded, appearance treatment is required in the production stage, and this appearance treatment may include grinding and painting.

[0025] The left and right side bars 1 are provided with plugging grooves 15 , which are arranged on the inner side surfaces of the side bars 1 , and the cover plate 2 is plugged and fixed through the plugging grooves 15 .

[0026] The lower part of the ceiling is provided with a plug seat 11 at the tail end of the two side bars 1 and at the lower part of the junction of the side bars 1 and the transverse front bar 12. A plug rod 5 is embedded in each plug seat 11. The structure of the plug rod 5 is as follows: Figure 2 , 3 As shown in FIG. 5 , a plug groove 51 and a plug protrusion 52 are provided on the outer diameter of the plug rod 5, and an upper fixing hole 53 is provided on the inner side of the plug rod 5. The upper fixing hole 53 can be a threaded hole. The upper fixing hole 53 is provided on the inner side of the plug rod 5. This design can protect the rivet part and prevent it from being frequently invaded by rainwater and corroded by it.

[0027] The four plug-in rods 5 are respectively connected with columns, which are divided into front columns 3 and rear columns 4. The bottom of the front column 3 is provided with a bent plug-in portion 33 and a front bottom positioning hole 32; the bottom of the rear column 4 is provided with a rear bottom positioning hole 41. Figure 6 As shown, the bent plug-in portion 33 designed by the utility model is inserted into the front plug-in hole 81 in the front windshield 8 of the cab, and the rear column 4 designed by the utility model is inserted into the rear plug-in hole 91 in the rear wheel protection part 9. After the above structure is set, during the client assembly, the front column 3 and the rear column 4 can be fixed with screws or rivets inside the front windshield 8 of the cab and inside the rear wheel protection part 9 respectively after plug-in assembly. This fixing method can be quickly screwed and fixed by a manual screwdriver or an electric screwdriver, and the assembly and subsequent disassembly and maintenance are relatively convenient. When designing, the stability of the plug-in with the column is improved by constraining the tolerance size of the rear plug-in hole 91 and the front plug-in hole 81.

[0028] Furthermore, a hole matching the plug-in groove 51 and the plug-in protrusion 52 is provided on the top surface of the column. Through this axial hole concave-convex plug-in fit, the stability of the front column 3 and the rear column 4 after assembly is improved, and radial displacement of the front column 3 and the rear column 4 and the plug-in rod 5 after plugging and fixing is avoided.

[0029] Through the above structural setting, the utility model realizes the split structural design of the ceiling itself, which is convenient for shipment and subsequent maintenance and replacement; the utility model also realizes the split structural design of the ceiling and the columns, and the columns can be divided into front columns and rear columns, both of which can be quickly connected with the ceiling respectively. During transportation, the ceiling and the columns are completely separated, and the ceiling and the columns can be packed separately, which improves transportation efficiency and reduces losses caused by collisions during transportation.

[0030] Embodiment 2:

[0031] Based on the structure of Example 1, the utility model takes product cost control into consideration during actual production. If the cover plate 2 is made of plastic, fiberglass or carbon fiber, there is basically no need to consider the corrosion resistance of the cover plate 2. However, when the above materials are used, an injection mold or an extrusion mold must be used. This type of production method has low production efficiency and high cost.

[0032] When the cover plate 2 is made of metal material, such as stainless steel or aluminum alloy, the technicians in this field can use a stamping die to form it. As is known, the stamping die has a high forming efficiency and can reduce the production cost to a certain extent while ensuring the strength. However, if such a metal material is used, it must be treated with anti-corrosion. In this embodiment, after the cover plate 2 is inserted into the plug slot 15, a sealant is usually applied to the joint gap on the top surface. In order to prevent external water from entering the plug slot 15, the utility model is provided with a countersunk hole 13 on the rear end of the side rod 1, and a threaded hole 14 is provided in the countersunk hole 13; an end cap 6 is provided corresponding to the countersunk hole 13, such as Figure 5 As shown, the end cover 6 is a stepped shaft structure, which is provided with a screw section 64, a countersunk hole matching section 63 and an outer end face 61; the screw section 64 is threadedly matched with the threaded hole 14, and the countersunk hole matching section 63 is axially plugged with the countersunk hole 13. Further, an annular T-shaped groove 62 is provided on the outer end face 61, and a flexible sealing gasket 7 is provided in the annular T-shaped groove 62, and a rubber strip protrusion 71 is provided on the flexible sealing gasket 7 corresponding to the annular T-shaped groove 62. After the two are tightly matched, the flexible sealing gasket 7 can realize the extrusion seal between the left and right side rods 1 and the end cover 6 to prevent external rainwater from intruding and avoid water seepage into the interior through the end of the plug-in groove 15 to cause metal corrosion. When replacing the cover plate 2, the end cover 6 can be screwed down to achieve replacement.

[0033] Those skilled in the art may also design the outer end surface 61 to be hollow inside, and make the outer end surface 61 of a transparent plastic material, and set an indicator light in the hollow area inside the outer end surface 61. After installing the end cover 6, it can be used as an indicator light or a turn signal.
