Referring to Fig. 2, Fig. 3, and Fig. 4, one embodiment of the integrated handrail structure of the present invention is assembled on a locomotive, and the locomotive can be a fuel vehicle or an electric vehicle. The lamp holder 6 on the lower part of the vehicle body cover 3 and on the rear armrest 4 is locked. First, define a first axis A, a second axis B, and a third axis C that are arranged at an angle between any two of them. The first axis A generally extends up and down along the height direction, the second axis B generally extends horizontally along the left and right directions, and the third axis C generally extends slightly obliquely along the front and rear directions. In this embodiment, preferably, the second axis B and the third axis C are perpendicular to each other. It should be noted that in this embodiment, the first axis A, the second axis B, and the third axis C may be shifted somewhat due to tolerance or misalignment during actual locking, so it should not be limited to this. In addition, the lock mentioned in this embodiment is locked by bolts or fasteners. However, in order to avoid excessive confusion in the drawings, the illustrations of bolts or fasteners are omitted in the drawings of this case. The vehicle body cover 3 is located above the vehicle frame 2 and has two openings 31 (only one of which is shown in FIG. 4 ) which are respectively located on the left and right sides and penetrate from the top surface to the top surface.

Referring to Fig. 4 to Fig. 7, the rear armrest 4 includes a connection seat 41 combined with the vehicle body cover 3 along the first axial direction A, two side handle bodies 42 respectively extending forward from the left and right sides of the connection seat 41, two fixing flanges 43 respectively protruding outward from the front ends of the plurality of side handle bodies 42 toward the left and right sides, two extension arms 44 respectively extending downward from the ends of the plurality of side handle bodies 42 and passing through the plurality of piercing openings 31, and two respectively extending from the front ends of the plurality of side handle bodies 42 The fixing post 45 extends downward and is located between the plurality of fixing flanges 43 and the plurality of extending arms 44 along the front-rear direction. The connecting seat 41 has a base portion 411 extending downwards and passing through the body cover 3 , and the base portion 411 is locked to the vehicle frame 2 through locking. The aforementioned locking direction is to lock along the first axis A perpendicular to the ground. Each side handle body 42 is recessed from outside to inside along the left-right direction to form an inserting groove 421 . Each extension arm 44 passes downward through the corresponding opening 31 , and its bottom end is connected to the vehicle frame 2 along the second axis B parallel to the ground through locking.

Referring to Fig. 4, Fig. 8, and Fig. 9, the maximum width between the plurality of side handle bodies 42 in the left-right direction is smaller than the maximum width in the left-right direction between the plurality of side decorative covers 5 (see Fig. 8), which makes the rear armrest 4 not wider than the plurality of side decorative covers 5 in the left-right direction, so that the rear seat passengers are not easy to get stuck when grasping the rear armrest 4, and can also avoid collisions. Each side trim cover 5 includes a main cover body 51 that is connected to a side handle body 42 on the same side and shielded from the outside of the corresponding fixing flange 43, a limiting flange 52 that protrudes inwardly from the main cover body 51 in the left and right direction and is located in front of the fixing flange 43, a plurality of locking pillars 53 that protrude inwardly from the main cover body 51 in the left and right direction, a plurality of buckles 54 that protrude inwardly from the main cover body 51 in the left and right direction, and a body cover. The outline of 51 protrudes inwardly along the left-right direction and corresponds to the boundary flange 55 of the outline of the side handle body 42 . The outer surface of the main cover body 51 is joined with the outer surface of the corresponding side handle body 42, thereby defining a joint surface D which is a continuous curved surface. Through this design, the rear armrest 4 and the side decorative cover 5 present a sense of unity and streamline in shape. In actual design, the top surface of the side handle body 42 is not lower than the top surface of the main cover body 51, and the side handle body 42 can have rounded corners at the front end due to its manufacturing process, so that the plurality of side decorative covers 5 can be connected through the rounded corners, so that the connection between each side handle body 42 and the corresponding side decorative cover 5 is smooth. In addition, through the auxiliary limit of the boundary flange 55, the step difference between the rear armrest 4 and the side decorative cover 5 can be minimized when assembled. Both this feature and the design of the rounded corners allow the user not to be cut by the step difference at the junction when reaching out to grab the rear armrest 4 .

Referring to Fig. 5, Fig. 9, and Fig. 10, the limiting flange 52 abuts against a corresponding fixing flange 43, and locks and fixes each other along the third axis C, so that the difficulty of assembly can be reduced and the effect of auxiliary positioning and assembly can be achieved. Each locking post 53 has a shaft portion 531, and a plurality of projections 532 protruding radially outward from the shaft portion 531. One of the plurality of locking posts 53 is fixed on the corresponding side handle body 42 along the second axial direction B. Furthermore, the locking post 53 is inserted into the inserting groove 421 of the side handle body 42, and a further layer of positioning can be produced through the tooth-shaped projections 532, which makes the side decoration When the cover 5 is combined with the side handle body 42 , the locking column 53 is easier to align, and can eliminate the forming error of the single product components, so as to avoid the misalignment of the side decoration cover 5 and the side handle body 42 after assembly. The other locking posts 53 and the plurality of buckles 54 are interlocked with the vehicle body cover 3 and other vehicle body components along the second axis B, so that the degree of freedom in assembling with the vehicle body cover 3 can be retained. It should be further explained that, through the fixing of the limiting flange 52 and the fixing flange 43 along the third axis C, and the fixing of the aforesaid locking column 53 and the insertion groove 421 along the second axis B, two locking points with locking directions perpendicular to each other are formed, which can increase the assembly rigidity of the plurality of side trim covers 5 and the rear armrest 4 and produce constraints in two directions. Preferably, the distance between the locking post 53 (that is, the one at the rear of the plurality of locking points) and the rearmost end of the side cover 5 is less than 30 mm. The rear locking point is designed to be close to the intersection of the borders, which can avoid the situation of gaps caused by manufacturing tolerances after assembly.

Referring to Fig. 3, Fig. 6, and Fig. 11, the lamp holder 6 is locked together with the rear armrest 4 along the first axis A, and the body cover 3 is sandwiched between the two, and preferably the lower frame E can be locked directly under the lamp holder 6. The lamp holder 6 of this embodiment is different from the conventional fixing method on the vehicle frame 2, but the lamp holder 6 is fixed on the vehicle body cover 3 and the rear armrest 4. After the seat 6 is combined with the vehicle body cover 3, the rear armrest 4 and the lower frame E, they are locked together on the vehicle frame 2, thereby reducing the assembly process and reducing the impact of tolerances.

3 and 4, in this embodiment, the vehicle body cover 3, the rear armrest 4, and the side trim covers 5 are fixed to each other through three non-parallel axes (the first axis A, the second axis B, and the third axis C), thereby improving structural rigidity and assembly rigidity, and eliminating the forming error between the rear armrest 4 and the plurality of side trim covers 5. In addition, the plurality of side decorative covers 5 can be respectively locked with the two side decorative covers F through part of the locking pillars 53, so that the plurality of side decorative covers F are respectively fixed below the plurality of side decorative covers 5, but on the other hand, the plurality of side decorative covers F can also be integrated with the side decorative cover 5 to produce a more integrated visual effect.

Referring to Fig. 3, Fig. 6, and Fig. 11, the assembly method of this embodiment (that is, the aforementioned pre-assembly method) is further described here. First, the rear armrest 4 and the plurality of side trim covers 5 are pre-assembled, and then the aforementioned parts are assembled with the vehicle body cover 3, and then the lamp holder 6 assembled with the lower frame E is assembled on the aforementioned components. On the armrest 4, as shown in Figure 6 and Figure 11, the weight of the lamp holder 6 can be sufficiently distributed to the body cover 3 and supported by the rear armrest 4, and finally the assembled whole is locked to the vehicle frame 2. This kind of assembling method is different from the conventional design in which each is locked on the frame 2, and it can avoid the misalignment of parts after assembly due to excessive manufacturing tolerance.

To sum up, the present invention connects the multiple side decorative covers 5 to both sides of the rear armrest 4 almost seamlessly and smoothly, so that the two form a joint surface D of a continuous curved surface, so that the modeling trend surface and the line are integrated seamlessly to produce an overall visual effect, and through the various configuration designs of the multiple side decorative covers 5 and the rear armrest 4, users can avoid collisions and cut hands when holding the rear armrest 4. In addition, in this case, the components are pre-assembled and then locked together on the frame 2. This way can avoid the situation of displacement between the aforementioned parts after assembly and maintain the quality of product appearance, so the purpose of the present invention can be truly achieved.

But what is described above is only an embodiment of the present invention, and should not limit the implementation scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
