Abstract
This case is related to a kind of upper tubing string with pressure forming stoping block and comprising its column assy, and the upper tubing string lateral wall is equipped with stoping block, and the stoping block is integrated the convex closure of punching press or extrusion forming；The upper tubing string with pressure forming stoping block and the column assy with tubing string on this of the utility model, not only simple process, high reliablity is convenient for automated production, and pollution is few in production process, product is not easy to get rusty, and high production efficiency, small, saving transport, keeping cost are relied on the buying of external supplier, production cost is effectively reduced, the upper tubing string for having welded type stoping block in prior art can be substituted completely.
Description
Technical field
The utility model belongs to auto parts field, and in particular to a kind of upper tubing string and packet with pressure forming stoping block
Containing its column assy.
Background technique
In many traffic accidents, steering column and steering wheel are the main components for making driver by personal injury,
When head-on crash occurs, the steering wheel on steering column is mounted on because car body deformation will be backward (i.e. towards driver's chest direction)
Movement, and driver will be to car body forward under effect of inertia.Although a part of inertia energy of driver can be by safety belt
Etc. restraint systems and air bag absorb, but huge inertia is difficult to all be absorbed by moment, and the head of driver and chest are still
Probably collide with steering wheel and generate injury, when serious even threat to life.Therefore, the life to protect driver
Safety, steering column need to have the function of absorbing Impact energy.
According to law, steering column hitting when the experiment dummy that relative velocity is 24.1km/h (=15mph) is hit
Hitting power should not be more than 1,134kgf (=2,500pounds), so needing to design impact energy absorption mechanism.In order to meet this
A condition needs that load appropriate and stroke is arranged in impact energy absorption mechanism.
Fig. 1 is a kind of existing column assy, and in current main-stream technique, stoping block C is fixed on by welding procedure
On the lateral wall of upper tubing string in product assembly；When vehicle crash, stoping block C collides with steering column upper end bracket A, seals at this time
Shell slide block B can automatically disengage from steering column upper end bracket A and take away quantitative cleavage energy (energy value ≈ 2000N), in this process
In, stoping block C collides with steering column upper end bracket A, falls capsule slide block B, consumes energy to fracture, absorbs impact force.
Stoping block C is easy to produce weld seam in the welding process, and welding slag splashes, and generates gases affect environment, and be welded into
This is big, the disadvantages of easily getting rusty.
In view of this, it is necessary to propose a kind of simple process, convenient for automated production, at low cost upper with stoping block
Tubing string.
Utility model content
There is pressure the purpose of the utility model is to provide a kind of high production efficiency, simple process, convenient for automated production
The upper tubing string of power molding stoping block.
Another purpose of the utility model is to provide a kind of at low cost, and pollution is few, it is not easy to get rusty have pressure at
The upper tubing string and column assy of type stoping block.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of upper tubing string with pressure forming stoping block,
The upper tubing string lateral wall is equipped with stoping block, and the stoping block is integrated the convex closure of punching press or extrusion forming.The stoping block
A compression moulding in mold with hydraulic press or press machine has equivalent resistance compared with upper tubing string shown in FIG. 1
Only effect and better reliability, simple process, high production efficiency, yield rate is good, is convenient for automated production.
Preferably, the upper surface of the stoping block and the upper tube column outer wall disconnect.
Preferably, the upper surface of the stoping block is vertical with upper tubing string.Upper surface is as straight with steering column upper end bracket
The prevention face of contact needs certain vertical contact area to guarantee to prevent effect.
Preferably, the stoping block is one of circle, taper, cube shaped.
Preferably, the stoping block is single.
Preferably, the stoping block is symmetrically arranged 2 or more.It is settable multiple in order to guarantee to prevent effect
Symmetrical stoping block.
Preferably, the stoping block height is greater than 2mm.To guarantee the prevention effect to steering column upper end bracket, prevent
Block and upper surface will have enough height, slippage when should prevent steering column upper end bracket from impacting stoping block.
Preferably, the upper tube column material is SPHC.
A kind of column assy, which is characterized in that including upper tubing string described in any of the above embodiments.
The upper tubing string with pressure forming stoping block and the column assy with tubing string on this of the utility model, no
Only simple process, high reliablity are convenient for automated production, and pollution is few in production process, and product is not easy to get rusty, and produces effect
Rate is high, small to the buying dependence of external supplier, saves transport, keeping cost, effectively reduces production cost, can substitute completely
The upper tubing string of welded type stoping block is had in prior art.
Detailed description of the invention
Fig. 1 is a kind of existing column assy；
Fig. 2 is the upper tubular column structure schematic diagram that the utility model has pressure forming stoping block；
Fig. 3 is the top view for the upper tubing string that the utility model has pressure forming stoping block.
Specific embodiment

Bright book text can be implemented accordingly.
Such as " have " it should be appreciated that used herein, "comprising" and " comprising " term are not precluded one or more
The presence or addition of a other elements or combinations thereof.
Embodiment 1
As shown in Figure 2,3, a kind of upper tubing string 1 with pressure forming stoping block, upper 1 lateral wall of tubing string are equipped with resistance
Stops 2, the stoping block are integrated stamping forming convex closure.
The upper surface 3 of the stoping block 2 and the upper tube column outer wall disconnect.
The upper surface 3 of the stoping block 2 is vertical with upper tubing string 1.
The stoping block 2 is triangular pyramidal.
The stoping block 2 is symmetrically arranged 2.
2 height of stoping block is 8mm.
