Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
It should be noted that the illustrations provided in the present embodiment are merely schematic illustrations of the basic idea of the present utility model.
The structures, proportions, sizes, etc. shown in the drawings attached hereto are for illustration purposes only and should not be construed as limiting the utility model to the extent that it can be practiced, since modifications, changes in the proportions, or otherwise, used in the practice of the utility model, are particularly adapted to the specific details of construction and the use of the utility model, without departing from the spirit or essential characteristics thereof, which fall within the scope of the utility model as defined by the appended claims.
References in this specification to orientations or positional relationships such as "front", "back", "upper", "lower", "left", "right", "intermediate", "longitudinal", "transverse", "horizontal", "inner", "outer", "radial", "circumferential", etc., are based on the orientation or positional relationships shown in the drawings, are also for convenience of description only, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and are not to be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 and 2, the present embodiment discloses a vehicle body including at least a first plate body 10 and a second plate body 20 formed in sections, the first plate body 10 and the second plate body 20 being integrally connected by a lap joint structure. Specifically, the overlapping structure includes a first overlapping portion 30 formed at an edge of the first plate body 10 and a second overlapping portion 40 formed at a corresponding edge of the second plate body 20, the second overlapping portion 40 overlapping over the first overlapping portion 30. It should be noted that, the manner of splicing the car body after the car body is segmented is in the prior art, and the number of segments of the segments can be set according to actual requirements, which is not repeated in this embodiment.
The first lap portion 30 of the present embodiment includes a groove 31 extending from the first plate body 10, and a first extension 32 extending from the groove 31; the second overlap 40 includes a second extension 41 extending from the second plate 20 and a fold 42 folded down from the second extension 41. During splicing, the second extension 41 is overlapped over the first extension 32, so that the flange 42 is positioned in the groove 31, and a gap 50 is left between the flange 42 and the bottom of the groove 31. The first extension 32 and the second extension 41 are bonded by structural sealant (B), and the seam 50 is connected with the flange 42 and the groove 31 by laser brazing (a).
In the vehicle body of the present embodiment, the first plate body 10 and the second plate body 20 are connected by a lap joint structure, so that the lap joint first extension section 32 and the lap joint second extension section 41 have a larger contact area, and the first lap joint portion 30 and the second lap joint portion 40 are connected by two connection modes of gluing and welding, so that the connection strength and the deformation resistance of the vehicle body can be effectively improved, and the overall strength of the vehicle body is improved. During the laser brazing process, the brazing filler metal is filled in the gap 50, so that the thermal influence is small, the first lap joint part 30 and the second lap joint part 40 can be firmly connected, and the appearance of the position is attractive.
In the first overlapping portion 30 of the present embodiment, the height of one side of the groove 31 connected to the first extension 32 is slightly lower than the height of the other side of the groove 31. The second extension 41 is preferably disposed at the same height as the second plate 20, so that the height difference between the first plate 10 and the second plate 20 can be reduced when the second extension 41 is overlapped with the first extension 32.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
