Description

Wooden automobile steering wheel

The utility model relates to a kind of vehicular spare parts, particularly relevant for a kind of wooden automobile steering wheel structure.

Press, the wooden automobile steering wheel structure of prior art please be read shown in Fig. 1,2, and it mainly is the steering wheel frame 10 that once cuts a reservation shape from log, offers a plurality of shrinkage pools 100 in the inner face pre-position of this steering wheel frame 10 again; One central bracket 11, this central bracket 11 have with above-mentioned shrinkage pool 100 numbers such as grade and radially distribute be embedded pin 110, this each be embedded pin 110 and to slightly bending of the same side, it is domed to make this central bracket 11 form central authorities, whole central bracket 11 is each earlier and is embedded pin 110 corresponding shrinkage pools 100, again with of the two sides mold pressing of special pressurization apparatus to this central bracket 11, make this domed central bracket 11 gradually smooth, and make simultaneously this each be embedded slightly outwards projection and wearing in the shrinkage pool 100 that is embedded in this steering wheel frame 10 of pin 110, reach the purpose that steering wheel frame 10 combines with central bracket 11.

Yet, the prior art wooden automobile steering wheel of above-mentioned structure, because central bracket 11 combines with steering wheel frame 10, be to utilize to impose the two sides mold pressing to being preset to domed central bracket 11, and make this central bracket 11 be embedded pin 110 respectively projection penetrate the shrinkage pool 100 of steering wheel frame 10 inner faces, so wear and get in the shrinkage pool 100 for making things convenient for each to be embedded pin 110, the domed radian of this central bracket 11 can not be too big, can make each be embedded pin 110 to wear near concordant angle, otherwise will be difficult to push combination, powerful extruding penetrates and then has bonding gap easily and produce defective products, thereby it is except combination, manufacturing is than outside the difficulty, and this central bracket 11 to be embedded the length that in fact pin 110 penetrate in the steering wheel frame shrinkage pool 100 also extremely limited, and there is not the anticreep left-hand thread fully, therefore in unexpected traffic accident incident, this bearing circle is made this central bracket 11 distortion because of inflicting heavy losses on most probably, the pin 110 that is embedded of central bracket 11 is taken out from steering wheel frame shrinkage pool 100 easily and is taken off, and then cause and stab the driver in mistiming collide to take place most probably, directly danger is coerced driver's life, so the safety of its use is troubling really.

Main purpose of the present utility model is promptly providing a kind of improved wooden automobile steering wheel structure, and it can make the central bracket of bearing circle and steering wheel frame anchoring strength strengthen, and improves safety in utilization, and is easier to make.

A kind of wooden automobile steering wheel that provides according to the utility model, it is characterized in that bearing circle comprise one group can half superimposed steering wheel frame of upper and lower correspondence, wherein this second steering wheel frame end face pre-position is provided with a plurality of caulking grooves, and this caulking groove has to limit and is embedded the blocking slot part that thing moves along bearing circle center radiation direction; One central bracket, this central bracket have count with above-mentioned caulking groove etc. and radially distribute be embedded pin, this each be embedded the terminal of pin and have shape and the cooresponding blocking of above-mentioned this caulking groove blocking slot part hook part, whole central bracket just is each and is embedded the corresponding caulking groove setting of pin and combines with this second steering wheel frame, this second steering wheel frame end face is coated with adhesives, suppresses superimposed first steering wheel frame on it.

Now be described with reference to the accompanying drawings the utility model and specific embodiment thereof.

Fig. 1 is a prior art three-dimensional appearance scheme drawing.

Fig. 2 is prior art extruding combination action scheme drawing.

Fig. 3 is the utility model three-dimensional appearance scheme drawing.

Fig. 4 is the utility model perspective exploded view.

Fig. 5 is the utility model combination cross-sectional schematic.

Prior art figure number part:

10 steering wheel frames

100 shrinkage pools

11 central bracket

110 are embedded pin

The utility model figure number part:

20 steering wheel frames, 200 half steering wheel frames

201 caulking grooves, 202 blocking slot parts

21 central bracket 210 are embedded pin

211 blocking hook parts

See also Fig. 3,4 and shown in Figure 5, wooden automobile steering wheel structure of the present utility model, it mainly comprises:

One group can superimposed formation one steering wheel frame 20 of upper and lower correspondence half steering wheel frame 200, wherein these second steering wheel frame 200 end face pre-positions are provided with a plurality of caulking grooves 201, and this caulking groove 201 has to limit and is embedded the blocking slot part 202 that thing moves along bearing circle center radiation direction; And this upper and lower half steering wheel frame 200 with the wooden pressing apparatus of song with the chi strip Qu Muyi helix spooling stickup shaping of exerting pressure simultaneously.

One central bracket 21, this central bracket 21 have with above-mentioned caulking groove 201 numbers such as grade and radial distribution be embedded pin 210, this each be embedded the terminal of pin 210 and have shape and above-mentioned caulking groove blocking slot part 202 cooresponding blocking hook parts 211, whole central bracket 21 just is each and is embedded the corresponding caulking grooves 201 of pin 210 and is provided with and combines with this second steering wheel frame 200, imposes superimposed this first steering wheel frame 200 of weight in these second steering wheel frame 200 end face coating adhesives again.

The wooden bearing circle of the utility model of said structure is when making, as long as in regular turn this second steering wheel frame 200, central bracket 21 and first steering wheel frame 200 superimposed holding toward the weight working machine are put the location, can make this central bracket 21 combine closely by the working machine one-step mould with steering wheel frame 20, and this kind structure is in conjunction with preventing effectively that from there is the gap in

central bracket

21 and 201 of steering wheel frame 20 caulking grooves, make more or less freely, processing procedure comparatively smoothness carries out, and the generation rate of defective products is lower; In addition since the blocking hook part 211 that each of this central bracket 21 is embedded pin 210 ends just can caulking groove blocking slot part 202 that should second steering wheel frame 200 be provided with, therefore the effective blocking hook part 211 of this central bracket 21 of blocking of the blocking slot part 202 of this second steering wheel frame caulking groove 201, prevent that this central bracket 21 is embedded pin 210 and takes out along steering wheel frame 20 center radiation directions and take off, so in unexpected traffic accident incident, even this bearing circle is subjected to big strength bump again and causes this central bracket 21 distortion, the pin 210 of being embedded of this central bracket 21 is determined not have and is taken out the misgivings of taking off from steering wheel frame 20, reduce the factor of danger side of body driver life, so the safety of its use is higher, overcome aforementioned prior art effectively because structure designs the perfect inadequately many shortcomings that produce.

In sum, wooden bearing circle of the present utility model has manufacturing and is easier to, and can improve the practical effect of safety in utilization.
