Abstract
The utility model provides a fixed structure of an accessory device on an intake manifold of an automobile, belonging to the technical field of an automobile, and aiming at solving the defects of the fixed structure between the existing intake manifold and the device such as complex technology, high price of copper alloy and the like, i.e. the problem of high production cost. The fixed structure of the accessory device on the intake manifold of the automobile comprises an installing seat disposed on the intake manifold and a fixed seat disposed on the accessory device, wherein a self-tapping screw is penetrated on the fixed seat, and a screw rod of the self-tapping screw is penetrated into the installing seat. The fixed structure of the accessory device on the intake manifold of the automobile has the advantages of being simple in technology, low in production cost, and firm in connection.
Description
Technical field
The utility model belongs to the vehicle technology field, relates to a kind of automobile inlet manifold, the fixed structure of fixture on particularly a kind of automobile inlet manifold.
Background technique
Automobile is meant that the power plant of self equipment drive, and generally has four wheels at least, does not rely on track and at the vehicle of land locomotion.Popularity rate at developed country's automobile is very high.Along with social economy ground is fast-developing, during the automobile popularity rate of less developed countries such as the nations of China and India also constantly improves.In order to enhance productivity and to reduce production costs, so people have proposed different ideas, as adjusting assemble sequence, transform assembling line and adjusting linkage structure or the like.
Intake manifold is one of parts of automobile indispensability, and it is between closure and engine air admittance door.Intake manifold generally adopts plastic materials to make, and on intake manifold fixtures such as intake temperature pressure transducer and oily rail injector assembly can be installed.
At present, above-mentioned device is all by being bolted on the intake manifold, and in order to make bolt can link to each other and guarantee join strength with intake manifold, then is embedded a link that adopts metallic material to make in the installation place of intake manifold.Link is to utilize the principle of expanding with heat and contract with cold to be plugged on the plastic air intake manifold after the intake manifold moulding; Above-mentioned link generally adopts Cu alloy material to make.In sum, fixed structure exists defectives such as complex process and Cuprum alloy cost an arm and a leg between intake manifold and the device, promptly exists the high problem of cost of production.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the fixed structure of fixture on a kind of technology is simple, cost of production the is low automobile inlet manifold.
The purpose of this utility model can realize by following technical proposal: the fixed structure of fixture on a kind of automobile inlet manifold, comprise fitting seat that is positioned on the intake manifold and the fixed base that is positioned on the fixture, it is characterized in that, be equipped with self tapping screw on the described fixed base, the screw mandrel of described self tapping screw penetrates in the fitting seat.
This fixed structure only needs self tapping screw is screwed into and toilet is installed is realized fixedly fixture, obviously have technology simply, handiness, problem that operating cost is low.The thickness of fitting seat should be greater than the thickness of intake manifold body, and self tapping screw promptly can be broken with the intake manifold brill after being screwed into fitting seat thus, can guarantee degree of being connected firmly again.
In the fixed structure of fixture, described fitting seat and intake manifold are connected as a single entity on above-mentioned automobile inlet manifold.This structure can directly adopt blow moulding and forming to obtain, so it is simple to have technology, and the advantage that cost of production is low.
On above-mentioned automobile inlet manifold, in the fixed structure of fixture, has the mounting hole that wears for self tapping screw on the described fitting seat.The effect that mounting hole promptly has the Primary Location self tapping screw is set, can prevents that again self tapping screw from squeezing fitting seat the danger of breaking.
On above-mentioned automobile inlet manifold in the fixed structure of fixture, the screw mandrel place of described self tapping screw increases progressively successively to the tapering of afterbody from the head.
In the fixed structure of fixture, described mounting hole is cylindrical counterbore on above-mentioned automobile inlet manifold.
In the fixed structure of fixture, the diameter of described mounting hole is slightly less than the diameter of self tapping screw head on above-mentioned automobile inlet manifold.
Compared with prior art, to have technology simple for the fixed structure of fixture on this automobile inlet manifold, the low and advantage that is connected firmly of cost of production.
Description of drawings
Fig. 1 is the perspective view of the fixed structure of fixture on this automobile inlet manifold.
Fig. 2 is the sectional structure schematic representation at A-A place among Fig. 1.
Fig. 3 is the structural representation of self tapping screw in the fixed structure of fixture on this automobile inlet manifold.
Among the figure, 1, intake manifold; 11, fitting seat; 12, mounting hole; 13, body; 2, fixture; 21, fixed base; 3, self tapping screw.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
To shown in Figure 2, automobile inlet manifold 1 comprises body 13 as Fig. 1, and fixture 2 is intake temperature pressure transducer and oily rail injector assembly.The fixed structure of fixture 2 comprises the fitting seat 11 that is positioned on the body 13, is positioned at the fixed base 21 on the fixture 2 and is located in self tapping screw 3 on the fixed base 21 on this automobile inlet manifold 1.Fitting seat 11 all adopts plastic materials to make with body 13 and fitting seat 11 is connected as a single entity with body 13.Has the mounting hole 12 that wears for self tapping screw 3 on the attachment face of fitting seat 11.Mounting hole 12 is cylindrical counterbore, and the diameter of mounting hole 12 is slightly less than the diameter of self tapping screw 3 heads.
The screw mandrel place of self tapping screw 3 increases progressively successively to the tapering of afterbody from the head.As shown in Figure 3, screw mandrel path place has more flat more sharp-pointed thread angle α, and α can be 20 °.β is located in the footpath in the screw mandrel, and β can be 30 °.With the internal thread extrusion modling, the machinability that the tooth end is sharp makes screw successfully screw in the mounting hole 12 to self tapping screw 3 in the process of precession, and the tooth body of directly locating broad in the screw mandrel can improve the pull off strength of screw, plays fastening effect.This self tapping screw 3 has reduced rotation torque, has improved pull off strength, has reduced fitting seat 11 is squeezed the danger of breaking.Use this screw both to reduce the technology difficulty of making intake manifold 1, saved cost again.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used intake manifold 1 morely; Fitting seat 11; Mounting hole 12; Fixture 2; Fixed base 21; Self tapping screw 3 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
