Description
Technical field
It the utility model is related to automobile seat accessories technical field, and in particular to a kind of lightweight motor vehicle seat back.
Background technology
The exploitation of new-energy automobile proposes new requirement to each parts, and light-weighted auto parts and components rise to energy emission reduction
To sizable effect, one of important spare part of the seat as automobile, while ensureing safe and comfortable, it is also desirable to mitigate
Weight is to adapt to the demand in low-carbon market.Traditional automobile chair frame is processed using common steel and is fabricated, this
Kind steel are advantageous in that with good mould processability and preferable welding performance, while also can guarantee that the strong of chair framework
Degree, its density conservation, even if using the high-strength steel sheet of special processing process, although remaining to maintain former frame strength will
Ask, also result in the decline of its mould processing characteristics and welding performance, and weight loss effect unobvious, it is therefore desirable to seek new light
Quantify material and coming of new technique to substitute the integrated skeleton of traditional steel, while meet the security strength requirement of skeleton.
Utility model content
To solve above technical problem, the utility model provides a kind of lightweight motor vehicle seat back.
Technical scheme is as follows：A kind of lightweight motor vehicle seat back, its key are：Including supporting plate, in the supporting plate

Length is equal.Using this design when when other accessories are installed in punching on the sheet material, when the bolt of assembling is because of one section of reasons such as vibration
Between after pilot hole can be caused to expand, but when bolt runs into reinforcing plate expand effect can reduce or stop, so can be effectively true
Bolt is protected not release.
The thickness sum of above-mentioned bottom plate, panel and the core plate is more than or equal to 15mm.
The material of above-mentioned panel and bottom plate is PP or ABS, and the material of the core plate is glass fibre or long fibre.Using
The material of this design supporting plate is relatively light and intensity is higher.
Above-mentioned anti-loose part is in the form of a column, and the direction of the external diameter of the anti-loose part along the screw rod to the head gradually increases
Greatly.Using this programme because the diameter of anti-loose part gradually increases, therefore only need to be further by bolt after the automatic expansion of pilot hole
Promote and tighten and can ensure that bolts assemblies fasten, without either perforate assembling or replacing are big again as plain bolt
Number bolt.
Above-mentioned anti-loose part includes locking bar, and one end of the locking bar is fixedly connected with the head, the locking bar
The other end is fixedly connected with the screw rod, and the outer wall of the locking bar is radially extended provided with disc.Disc is utilized using this design
Cooperation with locking bar prevents bolt from expanding pilot hole in pilot hole internal rotation, while also compares saving material.
Above-mentioned disc is triangle disc, and the inner edge of the triangle disc is fixedly connected with the outer wall of the locking bar, institute
The base for stating triangle disc is fixedly connected with the head.It may also function as using this design triangle shape disc and reinforce locking bar
Effect.
Above-mentioned anti-loose part is in truncated cone-shaped, and the bottom of the anti-loose part is fixedly connected with the head, the anti-loose part
Top be fixedly connected with the screw rod.Can directly be promoted after becoming big using this design pilot hole round table-like anti-loose part so as to
Make to connect fastening between bolt and sheet material again.
Above-mentioned screw rod is M8 or M10 screw rods, and the diameter on the head is more than or equal to 30mm.
Beneficial effect：It is that instead of motor vehicle seat back with porous supporting plate using the beneficial effects of the utility model
Skeleton or seat basin skeleton, because the sheet material uses three-layer combined material, particularly middle core plate uses hollow porous
Compared with traditional chair framework, its weight significantly reduces material, and the bolt assembled in supporting plate is because of one section of reasons such as vibrations
Pilot hole can be caused to expand after time, but expanding effect when bolt runs into reinforcing plate can reduce or stop, so can be effective
Ensure that bolt does not release.
