The invention is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the invention will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
Example 1
As shown in fig. 1 to 4, the invention provides a spliced automobile instrument beam, which comprises a beam rod piece 1, a section bar sub-piece 2 and two end plates 3.
The lateral wall of crossbeam member 1 is formed with at least one concatenation guide slot 11, concatenation guide slot 11 is followed crossbeam member 1 axial sets up and at least one end runs through crossbeam member 1 tip, in this embodiment, concatenation guide slot 11 numbers are 8, and 8 concatenation guide slot 11 is followed the even interval distribution of outer peripheral surface of crossbeam member, guarantees that crossbeam member 1 does not have specific direction restriction when using, has improved crossbeam member 1's commonality.
The maximum width of the cross section of the splicing guide groove 11 is larger than the opening width of the splicing guide groove 11.
The profile sub-piece 2 comprises a profile main body 21 and a matching part 22, wherein the matching part 22 is formed at one end of the profile main body 21, and the matching part 22 is matched with the splicing guide groove 11 in shape and is inserted into the splicing guide groove 11, so that the profile sub-piece 2 and the beam rod piece 1 are spliced together.
It should be noted that, according to this embodiment, the maximum width of the cross section of the splicing guide groove 11 is located near the middle of the splicing guide groove, and gradually decreases from the maximum width to the outside until the opening, so that the splicing guide groove can make the splicing guide groove clamp the profile sub-piece very well, and the mating part will not fall off from the opening of the splicing guide groove.
Through the spacing of concatenation guide slot, the dimensional accuracy of improvement instrument crossbeam assembly that can be very big reduces its welding jig's complexity, reduces the development cost of frock mould, to the different functional demands of different motorcycle types, only need change the concatenation form, splice position and the quantity of the section bar sub-piece of concatenation, just can realize the functional demand of different sizes, different grade motorcycle types, improved the commonality of section bar sub-piece, very big reduction development cost and the manufacturing cost of different motorcycle types, effectively reduce later maintenance cost.
In actual use, if the beam member and the section bar sub-member are not fixed, the structure of the instrument beam is unstable, and the safety requirement of the automobile cannot be met, in this embodiment, since the section bar sub-member is inserted into the splicing guide groove of the beam member through the matching portion, the section bar sub-member is located in the direction that can only move along the splicing guide groove, and only the motion of the matching portion along the splicing guide groove needs to be limited, the beam member and the section bar sub-member can be fixed, in this example, the matching portion 22 is provided with a connection point A along two ends of the length direction of the splicing guide groove 11, and the connection point A is fixedly connected with the beam member 1, and the fixed connection adopted here is preferably welding.
