Background technology
At present, with the issue of GB 32087-2015 light-duty vehicle draft gear standards, car puller hook installation point intensity is carried
Go out higher requirement, and conventional rear dragging hitch is connected not secured enough with vehicle body, in use, easily comes off or to vehicle
Body causes to damage, it is difficult to meet the intensity of national Specification or even endanger personal safety, and increase complicated rear dragging hitch and consolidate
Car body weight and manufacture cost can be increased by determining device, can not meet the purpose of body lightening.
The content of the invention
The purpose of this utility model is to provide a kind of trailer hook support assembly, solves conventional rear dragging hitch and is difficult to and vehicle
How body strong bonded the problem of connecting and trailer hook connects mechanism reach light-weighted problem.It can make trailer
Hook is securely connected with vehicle body floor side member, bears multi-direction force load, simple in structure light-weight.
Technical solution is used by the utility model：The trailer hook support assembly includes rack body, technical essential
It is：Rack body is formed by being connected with female car puller hook guide sleeve with the guide sleeve fixed plate with bending part, and car puller hook is led
Set is welded on the one side wall of vehicle body flute profile floor side member extension and slot bottom engaging portion, and car puller hook guide sleeve front end is stretched out floor side member and extended
The back wall of Duan Qianduan mends plate, and car puller hook guide sleeve one side wall is connected with neighbouring floor side member extension sidewall weld, car puller hook guide sleeve
Bottom and the slot bottom of floor side member extension are welded to connect；The top of car puller hook guide sleeve and another side wall and the welding of guide sleeve fixed plate are solid
Fixed, the both sides of guide sleeve fixed plate turn edge to be welded and fixed respectively with the side wall of floor side member extension and slot bottom, before guide sleeve fixed plate
Outer turn edge in end is welded and fixed with back wall benefit plate.
It is provided with and drags along floor side member length direction close to the side wall of longeron extension and the trench bottom of slot bottom engaging portion
The lower heavy platform of hitch guide sleeve bottom mating, the sinking concave station are welded and fixed with car puller hook guide sleeve.
The car puller hook guide sleeve is cylindrical shape.
The good effect that the utility model has is：The trailer hook support assembly by set car puller hook guide sleeve convenient for pair
Car puller hook is fixedly connected, and is consolidated by closing guide sleeve fixed plate with floor side member extension respectively to hitch guide sleeve two side and top and the bottom
Fixed connection, forms multi-faceted secured /V, can bear multi-direction force load, by the side to guide sleeve fixed plate with before
The fixation at end also significantly increases hitch guide sleeve and fixedly positioning, each portion when no matter car puller hook guide sleeve is subject to the power in which direction
Part can share stress jointly and transfer force in floor side member and squab panel assembly；Its is simple in structure, light-weight, has passed through
My company's CAE analysis, and pass through the strong seizure test of national legislation.The rear dragging hitch assembly is set by rational structure and technique
It counts, while the intensity requirement of GB 32087-2015 defineds is met, compared to other vehicles at least more than loss of weight 0.7Kg, is
Significant contribution is made in the lightweight of vehicle.
