Specific embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples.

As shown in figures 1-4, a kind of vehicle frame strengthens backplate with engine region, including frame assembly 1, internal stent 4, institute Internal stent 4 is stated on the main body rack 2 on 3 side of engine at extreme rear stent of frame assembly 1, main body rack 2 is concave shape Structure, for opening towards side, internal stent 4 is shape of chinese word Ji structure, and internal stent 4 is divided for bottom plate 43, top plate 44, side plate 45,44 both ends right angle setting side plate 45 of top plate, 45 bottom of side plate is vertically equipped with bottom plate 43 outward, and bottom plate 43 is equipped with and vertically passes through The hole worn, as transverse holes 42, side plate 45 is equipped with the hole extended vertically through, and as longitudinal hole 41, longitudinal hole 41 is with transverse holes 42 It is staggered, the distance at 43 both ends of bottom plate is identical with the inboard width of main body rack 2, and internal stent 4 is mounted on main body rack 2 Interior, bottom plate 43 is adjacent to the inner edge of the interlude of main body rack 2, is contacted in main body rack 2 with the lateral fixing bolt 6 of bottom plate 43 Position is equipped with corresponding aperture, sets a bolt, across the transverse holes 42 of internal stent 4 and the aperture of main body rack 2, as Then lateral fixing bolt 6 tightens the nut 7 of lateral fixing bolt 6；The both sides of top plate 44 and the two sides of main body rack 2 are supported Close contact, the position that the longitudinal hole 41 of side plate 45 is corresponded in main body rack 2 set aperture, a bolt are set, across main body branch The aperture of frame 2 and the longitudinal hole 41 of internal stent 4 as longitudinally fixed bolt 5, then tighten the nut of lateral fixing bolt 6 7。

43 thickness of bottom plate is more than side plate 45, and 45 thickness of side plate is more than top plate 44.It is so designed that, is arrived based on bottom plate 43 After dynamics between top plate 44 is disperseed, thickness has been able to the requirement for meeting support, therefore reduces thickness, can effectively save About material, while reduce weight.

Chamfering 46 is equipped between the side plate 45 and top plate 44.Chamfering 46 is that post-production forms herein, to increase inside The elasticity of stent 4, internal arc section are capable of the support force of the offer corner of bigger, avoid that whole fracture occurs.

The installation direction of the transverse direction fixing bolt is from internal stent 4 to main body rack 2.So that the later stage tightens nut 7 When have enough spaces.

The bottom plate 43 is enclosed with hard alloy layer, preferably 42CrMo platings in its contact surface side with main body rack 2 Layer, to reduce friction damage between the two.

When frame assembly 1 collides, since main body rack 2 and internal stent 4 form a MULTILAYER COMPOSITE The supporting surface of structure, stability further enhance, and bottom plate 43, side plate 45, top plate 44 form internal support system, can give External main body rack 2 provides the support force of bigger, and is bolted, and can be selected it specific according to the position of engine Position, if engine is longer, may be used two series connection modes, if engine is shorter, as shown in Figure 1, using in one Portion's stent 4 is installed between two parties.

The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the utility model, it is any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model Hold, any simple modification, equivalent change and modification that foundation the technical essence of the utility model makees above example, still Belong in the range of technical solutions of the utility model.
