In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a truck body top cap and back shroud connection structure, includes the top cap assembly, and back shroud assembly, left side enclose assembly and right side enclose the assembly, back shroud assembly comprises back shroud body and back shroud reinforcing plate, the top cap assembly comprises roof body and the roof in the reinforcing beam, the upper portion of back shroud body extends forward and is provided with the turn-ups at the end of extending, the turn-ups carries out Z with the top cap body to the overlap joint, and resistance welding is connected, back shroud body and turn-ups and top cap body connect into a closed cross-section's back top crossbeam, the turn-ups both ends of back shroud body enclose assembly and right side and enclose the B post inner panel upper portion joint of assembly and form the closed connection and form the three closed loop configuration of side shroud ring, top cap ring and back shroud ring that runs through last A post, B post and back top crossbeam.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a back bounding wall body upper portion material limit extension sets up the turn-ups, constitutes two rows of solder joints with the top cap body and is connected, forms a closed cross section's back top crossbeam, and the turn-ups both ends and the left side of back bounding wall body enclose assembly and right side and enclose assembly B post inner panel upper portion joint and form and seal the connection, form a side surrounding ring, top cap ring and the three closed annular structure of back surrounding ring that runs through A post, B post and back top crossbeam. Compare the traditional driver's cabin that top cap and back panel's open type single row solder joint are connected, increased two closed loop structures of top cap ring and back shroud, can effectively promote the whole mode of driver's cabin and torsional rigidity, can promote the durability and the NVH performance of driver's cabin. On the premise of meeting the performance target, the section size and the sheet metal material thickness can be optimized, and the lightweight design of the cab is realized.

Detailed Description
To make the objectives, technical solutions and advantages of the present application more clear, the present invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
Examples
As shown in fig. 1 to 5, in the present embodiment, a truck body roof and back panel connecting structure is provided, and it should be noted that the terms such as "first", "second", "third", and the like in the present embodiment are only used for distinguishing similar components, and are not to be construed as a specific limitation to the protection scope. In addition, the terms of orientation such as "bottom", "top", "side edges", and the like in the present embodiment are explained based on the drawings.
This truck body top cap and back panel connection structure, including top cap assembly 4, back panel assembly 5, left side encloses assembly 6, right side encloses assembly 3, wherein top cap assembly 4 comprises top cap body 8 and the roof reinforcing beam that adds in the top cap, back panel assembly 5 comprises back panel body 7 and back panel reinforcing plate, the upper portion of back panel body 7 extends forward, and be provided with turn-ups 9 at the end of extending, turn-ups 9 carries out Z to overlap joint with top cap body 8, and resistance welding connects, the welding forms one row of solder joint, back panel body 7 and turn-ups 9 connect into a closed cross-section's back top crossbeam with top cap body 8, turn-ups 9 and top cap body 8's one row of solder joint and the original top cap body 8 rear end and back panel body 7's one row of solder joint connect top cap body 8 and back panel body 7 into a closed cross-section's back top crossbeam, the turn-ups 9 both ends of back panel body 7 form with the B post inner panel upper portion joint that left side encloses assembly 6 and right side enclose assembly 3 And three closed ring structures of a side surrounding ring, a top cover ring and a rear surrounding ring which penetrate through the upper column A, the column B and the rear top beam are formed in a closed connection mode.
