Description
Technical field
The utility model belongs to the technical field of fastening member in mechanical engineering, and in particular to a kind of aluminium sleeve connector and
Aluminum vehicle frame with aluminium sleeve connector.
Background technology
With the worsening shortages of resource, energy-saving and environment-friendly idea deepens continuously, and conventional gasoline car cannot adapt to society again
The development of meeting, electric automobile is as a kind of new energy motor, because of its outstanding advantage in terms of energy-saving and environmental protection so that electronic
The research and extension of automobile becomes the hot spot of automobile industry in recent years.
Electric automobile provides power source by the electric power of battery storage, its cruising ability is always the short of electric automobile
Plate, and the emphasis of consumer's concern；To lift cruising ability, car reaches related research and development department except improving battery pack at present
Power reservoir capacity in terms of work outer, the dead weight for reducing automobile as far as possible is also an important side for solving how to be lifted cruising ability
To.To reduce automotive dead weight, vehicle structure is changed into new from traditional steel vehicle frame, vehicle body by welding or being threadedly coupled
The aluminum vehicle frame of structure and the vehicle body of new material；When welding technique is unsuitable for the connection of Novel frame and vehicle body, spiral shell is still elected to
The mode of line connection；But the internal thread hole processed on aluminum vehicle frame is insufficient there are intensity the problem of, screw thread is easy to wear, staggeredly
Or damage.Also there is the technical solution of enhancing aluminium bolt strength in the prior art, in CN206320151U, by aluminium bolt
Endoporus bonding Steel Bolt carrys out the intensity of strengthened thread, but the reliability being bonded is to its overall service life and structure safe to use
It is alternative not strong into threat；Meanwhile further to mitigate vehicle frame dead weight, material is reduced, reduces material and processing cost, aluminium
Use of the section bar processed on vehicle frame is more and more, and aluminium section is because it extrudes integrally formed engraved structure, no sufficient
Enough metal parts to form internal thread hole to process；It is therefore desirable to study a kind of new connector（Or body frame structure for automotive）To solve
The problem of Novel frame is connected with vehicle body.
Utility model content

Bolt connect vehicle body.In this way, the problem of aluminum internal thread hole intensity is insufficient effectively prevent by steel-wire screw-socket；This practicality
It is new except for connecting vehicle frame and vehicle body, mainly still suffering from pulling force of the vehicle body to vehicle frame, and the setting of flange makes vehicle body
Pulling force is effectively delivered on vehicle frame by the abutting of flange and aluminium section internal stiffeners, is avoided completely by sleeve body two
The weld part of end face bears and transmits pulling force, avoids the damage of welding position, ensure that sleeve body and the globality of vehicle frame；
By the setting of chamfering in sleeve body, facilitate the filling of welding base metal, ensure the continuity of weld seam, effectively prevent stress collection
In, well ensure sleeve body and Frame Welding and connect the weld strength at place, further ensure sleeve body and vehicle frame
Globality.
Above-mentioned technical proposal is further improved, one end that the sleeve body is equipped with flange is equipped with chip removal along its length
Hole, the chip-removal hole connect the internal thread hole and coaxial with the internal thread hole.
In this way, the chip removal during internal thread of internal thread hole easy to process, avoids screw tap fracture from causing process tool and processing
Part rejection, causes material, frock and artificial waste；Meanwhile further mitigate weight.
Further, the internal diameter of chip-removal hole and the path of internal thread hole are corresponding.
In this way, reducing the outfit of the frocks such as cutter, cost is reduced；Meanwhile the bolt for connecting vehicle body can be from sleeve sheet
The either end of body loads, and practicality is good.
Preferably, the sleeve body is cylindrical-shaped structure and coaxial with the internal thread hole, and the flange is convex annular
Platform and coaxial with the internal thread hole.
In this way, whole part is revolving meber, and it is low to process equipment and frock requirement, only need clamped one time to complete processing, work
Skill is simple, and manufacture cost is low；Meanwhile facilitate the processing for the stepped hole being correspondingly arranged on connected vehicle frame.
The utility model also relates to a kind of aluminum vehicle frame with aluminium sleeve connector, including aluminium section and aluminium set
Cylinder connector, the aluminium section have at least one internal stiffeners, and the aluminium sleeve connector is any of the above-described kind of aluminium set
Cylinder connector；The aluminium sleeve connector opens up corresponding with the shape of sleeve body and flange on the aluminium section
Mounting hole in, the end face in flange towards the internal thread hole direction is connected on the internal stiffeners；The aluminium section
It is fixedly connected by welding with the aluminium sleeve connector.
Above-mentioned technical proposal is further improved, the shape of the both ends of the surface of aluminium sleeve connector is corresponding with aluminium section respectively
The shape of outer surface is corresponding and concordant；Filled with the solidfied material after welding at the chamfering.
Since above-mentioned aluminium sleeve connector has the effect above, the aluminum vehicle frame with above-mentioned aluminium sleeve connector is with same
The effect of sample, is not repeated herein.
Compared with prior art, the utility model has the advantages that：
1st, the utility model can effectively realize the connection of novel aluminium section bar vehicle frame and vehicle body.
2nd, the utility model is by the setting of flange and chamfering, the intensity that guarantee sleeve body is connected with vehicle frame well,
The good integrity of sleeve body and vehicle frame.
3rd, the utility model effectively prevent the problem of aluminum internal thread hole intensity is insufficient by steel-wire screw-socket, avoid aluminum
Internal thread abrasion, interlock or damage, and ensures the intensity of connection.
4th, the utility model realizes effective loss of weight of vehicle frame and connector itself, and reaching indirectly makes automotive energy-saving emission-reducing,
Lift the effect of automobile cruising ability.
