Abstract
The utility model discloses a plastic positioning safety block structure mainly comprising a positioning safety block, a mounting plate and a positioning safety block cover plate, wherein the positioning safety block cover plate is installed in the positioning safety block; the positioning safety block and the mounting plate are connected into a whole through the positioning safety block cover plate; and plastic members are adopted by the positioning safety block and the positioning safety block cover plate. With the structure, the problem of large collapsing energy absorption range of a tubular column when an automobile provided with C-EPS has a collision is solved, the harm on a driver is reduced, and the effects of simple process, high production efficiency and low production cost are achieved.
Description
Technical field
The utility model relates to pipe column type vehicle electric power-assisted steering device tubing string external structure, is specially plastics location safety block structure.
Background technology
Pipe column type vehicle electric power-assisted steering device (to call C-EPS in the following text) mainly is the characteristic curve that utilizes torsion bar, the torsional deflection of torsion bar is changed into the longitudinal travel of slide block, the contact torque sensor detects and transmits axial displacement signal, controller carries out comprehensive computing to each signal, the size of control servomotor horsepower output.Because of C-EPS is auto parts and components, its safe reliability is most important.Can in whole steering swivel system, play a part very important so the location safety block structure among the C-EPS effectively control crumple power.
At present, location safety block structure such as Fig. 4, shown in Figure 5 of domestic traditional C-EPS.Location safety block 1b utilizes the plastic column 3b of injection moulding to be fixed on the adapter plate 2b.When automobile bumps, safety block 1b is motionless in the location, and adapter plate 2b locatees the crumple power at safety block place this moment and is made up of the friction force two parts between shearing force, location safety block 1b and the adapter plate 2b of plastic column 3b to left movement, and the constant diameter of plastic column 3b, so shearing force substantially constant.Therefore crumple power being control effectively mainly is to realize by adjusting the friction force of locating between safety block 1b and the adapter plate 2b.
The location safety block 1b of traditional C-EPS adopts the cast aluminium member, and adapter plate 2b adopts steel component, and both friction coefficient are bigger, because pressure has certain mobility scale, so the change in friction force scope is bigger, thereby causes crumple power to be not easy control; Locate safety block 1b in addition and adopt the cast aluminium member, material cost own and tooling cost are higher, have increased purchase cost; And plastic column 3b adopts polyformaldehyde injection molded, complex process, and production efficiency is low, and productive costs is also higher.
The utility model content
The technical matters that the utility model solved is to provide a kind of plastics location safety block structure, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved realizes by the following technical solutions:
Plastics location safety block structure mainly comprises location safety block, adapter plate, location safety block cover plate, and it locatees the material that the remarkable distinguishing characteristics of insurance block structured is to locate safety block and adapter plate connecting mode and location safety block with tradition.
In the utility model, described location safety block cover plate is packed into and is located in the safety block, and the location safety block is connected as a single entity by location safety block cover plate and adapter plate, and this connecting mode has replaced traditional acetal plastic post connection mode, cheap, reduced productive costs.In the utility model, described location safety block and location safety block cover plate adopt plastic member, have reduced location safety block and adapter plate friction coefficient, have effectively controlled the change of location safety block place's crumple power.
In the utility model, safety block inside, described location can also be provided with skeleton, and skeleton generally adopts steel component.
Beneficial effect: the utility model solved C-EPS is housed automobile when bumping, the big problem of tubing string generation crumple energy-absorbing scope reduced the injury to chaufeur, and technology is simple, the production efficiency height, productive costs is low.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, plastics location safety block structure, mainly comprise location safety block 1a, adapter plate 2a, location safety block cover plate 3a, its difference is to locate safety block 1a with adapter plate 2a directly adopts safety block cover plate 3a to be connected as one with tradition location insurance block structured notable feature, and location safety block 1a and to locate safety block cover plate 3a be plastic member.
Referring to Fig. 2, first kind of specific embodiment A-A of plastics location safety block structure directional profile scheme drawing, described location safety block cover plate 3a packs into and locatees among the safety block 1a, and location safety block 1a is connected as a single entity by location safety block cover plate 3a and adapter plate 2a; Described location safety block 1a and location safety block cover plate 3a adopt plastic member, have reduced location safety block and adapter plate friction coefficient, have effectively controlled the change of location safety block place's crumple power.
Referring to Fig. 3, second kind of specific embodiment A-A of plastics location safety block structure directional profile scheme drawing, the structure basically identical of its structure and specific embodiment one just also is provided with skeleton 4 in safety block 1a inside, location, skeleton 4 adopts steel component, increases the mechanical strength of location safety block.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
