Abstract
The invention discloses a plastic bearing plate for a steering wheel. The plastic bearing plate is used for being matched with an upper cover of the steering wheel for fixing an airbag. The plastic bearing plate comprises a bottom plate and side walls, wherein the periphery of the bottom plate extends upwards to form the side walls. A round opening is formed in the center of the bottom plate. Four first locating holes are formed in the periphery of the round opening. The two opposite sides of the bottom plate extend downwards to form protruding blocks. Second locating holes are formed in the protruding blocks. A plurality of buckling parts are arranged on the outer surface of the side wall. The invention further discloses a steering wheel applying the plastic bearing plate. The plastic bearing plate for the steering wheel and the steering wheel are used for solving the problems that a metal bearing plate of the automobile steering wheel in the prior art deforms easily and is inconvenient to install.
Description
Technical field
The present invention relates to a kind of tray and bearing circle, particularly relate to a kind of bearing circle plastics tray and bearing circle.
Background technology
At present, usually adopt the tray of metal material to coordinate with the upper cover of bearing circle in vehicle steering and fix air bag.But the cost of development of metal tray is higher, and easily there is the problem of deformation of products after being connected with bearing circle body.In addition, metal tray needs to be connected with bearing circle upper cover by rivet, is not easy to product and installs.
Summary of the invention
The invention provides a kind of bearing circle plastics tray and apply the bearing circle of this plastics tray, yielding and be not easy to the problem of installing with the metal tray solving vehicle steering in prior art.
The invention provides a kind of bearing circle plastics tray, for coordinating fixation balloon with the upper cover of bearing circle, the sidewall that plastics tray comprises base plate and upwards extended to form by base plate surrounding, base plate center arranges circular open, at the periphery of circular open, four the first knock holees are set, the relative both sides of base plate are extended with projection downwards, projection are arranged the second knock hole, and the outside face of sidewall arranges multiple clamping part.In addition, the lower surface of base plate is provided with multiple guidepost, and guidepost is positioned at the outside of the first knock hole.
The present invention also provides a kind of bearing circle, comprise upper cover, air bag, producer and plastics tray, the sidewall that plastics tray comprises base plate and upwards extended to form by base plate surrounding, base plate center arranges circular open, at the periphery of circular open, four the first knock holees are set, the relative both sides of base plate are extended with projection downwards, projection is arranged the second knock hole, the outside face of sidewall arranges multiple clamping part, air bag is arranged between upper cover and plastics tray, plastics tray is fixed on upper cover by the clamping part of sidewall, producer is fixed on plastics tray by connecting element and the first knock hole.In addition, the base plate lower surface of plastics tray is provided with multiple guidepost, and guidepost is positioned at the outside of the first knock hole of base plate.
Bearing circle provided by the invention plastics tray adopts the mode of Snap joint to be connected with upper cover, can reach the object of assembling without the need to any accessory appliances and other parts.The stability of plastics tray is better than metal tray of the prior art, and plastics tray is not yielding, and after being connected with bearing circle body, error can control, more accurately.And the process-cycle of plastics tray is short, reduces development and manufacturing cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Figure 1 shows that the birds-eye view of the bearing circle plastics tray that present pre-ferred embodiments provides;
Figure 2 shows that the section-drawing along the dotted line AA ' direction in Fig. 1;
Figure 3 shows that the assembling schematic diagram of the plastics tray that present pre-ferred embodiments provides and bearing circle upper cover;
Figure 4 shows that the section-drawing along the dotted line BB ' direction in Fig. 3.
Detailed description of the invention
Figure 1 shows that the birds-eye view of the bearing circle plastics tray that present pre-ferred embodiments provides.Figure 2 shows that the section-drawing along the dotted line AA ' direction in Fig. 1.Figure 3 shows that the assembling schematic diagram of the plastics tray that present pre-ferred embodiments provides and bearing circle upper cover.Figure 4 shows that the section-drawing along the dotted line BB ' direction in Fig. 3.Please also refer to Fig. 1 to Fig. 4.
As shown in Figures 1 and 2, the bearing circle plastics tray sidewall 122 that comprises base plate 120 and upwards extended to form by base surrounding.The center of base plate 120 arranges circular open 123, and the periphery of circular open 123 is provided with four the first knock holees 124.In this, the line between first knock hole 124 at diagonal angle is between two mutually vertical, and namely an isosceles right triangle is determined in the center of circle of adjacent two the first knock holees 124 and circular open 123 together.The relative both sides (in this, being the left and right sides) of base plate 120 are extended with projection 125 downwards, projection are arranged the second knock hole 126.The outside face of sidewall 122 is arranged multiple clamping part 128.In this, be provided with clamping part 128 at the outside face of four sidewalls 122.In addition, the lower surface of base plate 120 is provided with multiple guidepost 129, guidepost 129 is positioned at the outside of the first knock hole 124.
As shown in Figures 3 and 4, bearing circle comprises upper cover 10, air bag 13, producer 11 and plastics tray 12.In this, air bag 13 is arranged between upper cover 10 and plastics tray 12.Plastics tray 12 is fixed on upper cover 10 by the clamping part 128 of sidewall 122.Specifically, the edge groove place that the clamping part 128 of plastics tray 12 can snap in upper cover 10 is fixed.Producer 11 is fixed on plastics tray 12 by connecting element and the first knock hole 124.In this, connecting element is such as screw 15 and nut 14, and screw 15 through the first knock hole 124 and producer 11 in the inside of plastics tray 12, is locked by nut 15, thus producer 11 and plastics tray 12 fixed.After plastics tray 12 and upper cover 10 combine, entirety is fixed to bearing circle body by the second knock hole 126 on plastics tray 12 and screw.In addition, the lower surface of the base plate 120 of plastics tray 12 is provided with multiple guidepost 129, and guidepost 129 is positioned at the outside of the first knock hole 124, the assembling of the miscellaneous part of convenience and bearing circle.
In this, plastics tray 12 take PA6+GF30 as material.Specifically, PA6 has good impact resistance and antilysis, in order to the problem that the hygroscopic property solving PA6 is stronger, adds glass fibre GF30 as additive.For the product not having additive, between the contraction 1% to 1.5% of PA6, and add glass fiber additives shrinkage percentage can be made to be reduced to 0.3%.So, the plastics tray with better performance can be obtained.
In sum, bearing circle provided by the invention plastics tray adopts the mode of Snap joint to be connected with upper cover, can reach the object of assembling without the need to any accessory appliances and other parts.The stability of plastics tray is better than metal tray of the prior art, and plastics tray is not yielding, and after being connected with bearing circle body, error can control, more accurately.And the process-cycle of plastics tray is short, reduces development and manufacturing cost.
Above-described embodiment does not limit the present invention in any way, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection scope of the present invention.
