Description
Technical field
The utility model belongs to electric car body construction field, and in particular to vehicle body fore sub frame installs point structure.
Background technique
Pure electric automobile is to use clean energy resource as the new automobile of drive energy, has the advantages such as environmental protection, efficient.State
One development trend of inside and outside automobile industry.But the course continuation mileage of pure electric automobile is a problem of pure electric vehicle field face.
On the vehicle body of electric vehicle, need to install the structural member of the high requests such as fore sub frame, and general traditional steel construction vehicle
Body riveting and welding performance are fine, are easier to realize connection structure and intensity is met the requirements.But using aluminum profile as bone
Electric car body made of frame, from self-riveting threaded sleeve, the intensity for welding threaded sleeve is restricted, therefore, vehicle body
Installation, the fixation of upper all kinds of structural members are greatly limited.
Utility model content
The utility model provides a kind of electric car body fore sub frame installation point structure, and the purpose is to overcome the prior art
Defect, realize all-aluminium body fore sub frame installation point firm installation and fixation.
To achieve the above object, the utility model uses following technical scheme:
Electric car body fore sub frame installs point structure, including front longitudinal beam, fore sub frame threaded sleeve, fore sub frame spiral shell
Line casing fixes bracket, fore sub frame installation bolt, fixed bracket fastening bolt, is provided on a side wall of the front longitudinal beam
Mounting hole, the fore sub frame threaded sleeve are fixed on bracket and are provided with through-hole corresponding with mounting hole；The fore sub frame
The fixed bracket of threaded sleeve is fixedly mounted on front longitudinal beam by fixed bracket fastening bolt, and interior spiral shell is equipped in the threaded sleeve
Line, fore sub frame installation bolt pass through mounting hole on front longitudinal beam, are then passed through on the fixed bracket of fore sub frame threaded sleeve
Through-hole after with the female thread of threaded sleeve at threaded engagement.
As advanced optimizing for the utility model, the fixed bracket of the fore sub frame threaded sleeve is one section and two intermediate
The structure of a side flanging, forms U-shaped connecting plate, and two side flangings are bonded with the inner wall at the both ends of front longitudinal beam respectively.
In addition, being provided with welded nut on described two side flangings.
Further, the fixed bracket of the fore sub frame threaded sleeve is arranged in the inner cavity of front longitudinal beam.
Further, front longitudinal beam, fore sub frame threaded sleeve, the support bracket fastened material of fore sub frame threaded sleeve are aluminium profiles
Material.
The fixed bracket of fore sub frame threaded sleeve processed by the utility model, can both make threaded sleeve position more
It is accurate to add, and more convenient when installation.Due to being welded with welded nut on the fixed bracket of fore sub frame threaded sleeve, indulged with preceding
Beam connection is just very convenient, need to only fasten in outside torque wrench by prescribed torque.In addition, vehicle body fore sub frame installation point
The fixed bracket of fore sub frame threaded sleeve is placed in the inner cavity of front longitudinal beam and will not cause to interfere to external installing component in structure,
The subframe mounting surface of front longitudinal beam is not likely to produce the metal plates failure modes such as deformation.Fixed bracket fastening bolt is passed through on front longitudinal beam
Perforation and the fixed bracket of fore sub frame threaded sleeve apply pretightning force, solve the fixed bracket of fore sub frame threaded sleeve preceding vertical
The fixation of beam relative position.
The advantages of the utility model or the utility model has the advantages that
(1) front stringpiece of vehicle body aluminum profile component processing difficulty reduces, and saves cost.
(2) structure is simple after improveing, lightweight.
(3) switching performance is excellent under harsh environment.
(4) compared with pressing, welding, preferable maintenanceability is threaded with, the advantages that the good quality of consistency easy control.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the explosive view of the utility model；
Wherein, 1, front longitudinal beam, 2, fore sub frame threaded sleeve fixation bracket, 3, welded nut, 4, threaded sleeve, 5, fixation
Bracket fastening bolt.
