Description

A kind of engine thermal insulation board installation nut and automobile
Technical field
The present invention relates to nuts, and in particular to a kind of engine thermal insulation board installation nut and automobile.
Background technique
The exhaust gas temperature of engine discharge is very high, can cause some adverse effects, such as city by other components to car body Occurred the tail pipe exhaust thing that spare tyre basin is burned on field.It is negligible for high-temp waste gas influence to be reduced to, usually Be in exhaust pipe and automobile non-refractory part thermal insulation board interval, so body insulation plate be typically located at engine two sides and Between body bottom exhaust pipe and floor.Thermal insulation board generally uses aluminium, and thickness is very thin.Welding screw on car body, passes through nut Thermal insulation board is fixed on the car body.
Referring to Fig. 1, shown in existing thermal insulation board nut is installed, 10 difference in height very little of hex nut head 9 and compact heap causes Nut feature to installation environment require it is relatively high, i.e., stud welding on the car body when, Yao Jinliang avoid stud root generate Welding slag, if once there is welding slag in root when stud welding, existing thermal insulation board installation nut will be pushed up, so that thermal insulation board and circle Gap is generated between cone compact heap, influences Assembly stability.In addition, circular cone compact heap area is smaller, to the cladding face of thermal insulation board Product is effective, so that there are abnormal sound risks for thermal insulation board.
Summary of the invention
The object of the present invention is to provide a kind of engine thermal insulation board installation nut and automobiles, and structure is simple, high reliablity, It is adaptable.
Engine thermal insulation board of the present invention installs nut, including inner wall sets threaded barrel nut main body, institute Nut main body one end is stated equipped with boss, the boss is equipped with the acting surface clamped for tightening tool, in the boss free end It is equipped with evacuation chamber equipped with the changeover portion that radial dimension becomes larger, in the changeover portion, is equipped in changeover portion free end outside The pressure plate of extension.
Further, the outer circumference surface of the boss is equipped with more than two acting surfaces, and in every two acting surface in convex Both ends on platform circumferencial direction are respectively equipped with cambered surface.
Further, the boss section is in pancake, hexagon or octagonal, and inside is equipped with the sky with evacuation chamber Chamber.
Further, the pressure plate is in a ring.
A kind of automobile, comprising: car body is fixed with projection welding stud on the car body;Thermal insulation board is located at car body and enging cabin Between, equipped with holding the through-hole that passes through of projection welding stud;Above-mentioned engine thermal insulation board installs nut, and the pressure plate and thermal insulation board paste It closes, nut main body is threadedly coupled with projection welding stud, and the evacuation chamber in changeover portion provides for the welding slag at projection welding Stud connection to be kept away Allow space.
The present invention between nut main body and pressure plate due to being provided with boss and changeover portion, so that nut main body and compression Difference in height between plate is larger, thereby reduces the welding requirements of projection welding stud, evacuation chamber provides in changeover portion for welding slag Avoiding space avoids the influence that welding slag installs nut, adaptable.Simultaneously as changeover portion free end is equipped with to extension The pressure plate stretched, pressure plate area coverage is larger, the fitting area of engine installation nut and thermal insulation board is increased, so that heat-insulated Plate is more firmly mounted, and improves the reliability of assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing thermal insulation board installation nut;
Fig. 2 is structural schematic diagram of the invention;
Fig. 3 is the sectional arrangement drawing of engine thermal insulation board installation nut of the invention.
In figure, 1-nut main body, 2-boss, 3-changeover portions, 31-evacuation chambers, 4-pressure plates, 5-car bodies, 6- Projection welding stud, 7-thermal insulation boards, 8-welding slags, 9-hex nut heads, 10-compact heaps.
Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
Referring to Fig. 1 and Fig. 2, engine thermal insulation board shown in installs nut, is formed using steel integrated punching, including inner wall If threaded barrel nut main body 1, described 1 one end of nut main body is equipped with boss 2, and the boss 2 is equipped with for tightening work Have the acting surface clamped, is equipped with the changeover portion 3 that radial dimension becomes larger in 2 free end of boss, is set in the changeover portion 3 There is evacuation chamber 31, in 3 free end of changeover portion pressure plate 4 with outward extension.
Acting surface there are six being set on the outer circumference surface of the boss 2, and in every two acting surface on 2 circumferencial direction of boss Both ends be respectively equipped with cambered surface.According to arrangement space or installation requirements, 2 section of boss can also be pancake octagonal, Inside is equipped with the cavity being connected to evacuation chamber 31, and the setting of cavity can reduce the dosage of steel, reduces engine thermal insulation board The overall weight for installing nut, meets body lightening demand.
The pressure plate 4 in a ring, ensure that engine thermal insulation board installation nut and thermal insulation board good fit, improve every The reliability of hot plate assembly.
A kind of automobile, comprising: car body 5 is fixed with projection welding stud 6 on the car body 5;Thermal insulation board 7 is located at car body 5 and hair Between motivation cabin, equipped with holding the through-hole that passes through of projection welding stud 6;Above-mentioned engine thermal insulation board installs nut, the pressure plate 4 with Thermal insulation board 7 is bonded, and nut main body 1 is threadedly coupled with projection welding stud 6, and the evacuation chamber 31 in changeover portion 3 is the connection of projection welding stud 6 The welding slag 8 at place provides avoiding space.
When specific assembly, projection welding stud 6 is fixedly welded on car body 5 first, then by thermal insulation board 7 be placed in car body 5 with Between enging cabin, the thread segment of projection welding stud 6 protrudes from heat-insulated plate surface, then engine thermal insulation board installation nut is screwed in, The thread segment corresponding matching of nut main body 1 and projection welding stud 6, evacuation chamber 31 is that welding slag 8 provides avoiding space in changeover portion 3, It avoids welding slag 8 and jacks up engine thermal insulation board installation nut, influence the assembly of engine thermal insulation board installation nut, avoid chamber 31 Setting increase engine thermal insulation board installation nut adaptability.Pressure plate 4 is close to 7 surface of thermal insulation board, and pressure plate 4 covers Area is larger, the fitting area of engine installation nut and thermal insulation board 7 is increased, so that being more firmly mounted for thermal insulation board 7, mentions The high reliability of assembly.
Although present disclosure is as above, present invention is not limited to this, what anyone obtained under the inspiration of the present invention Other various forms of products, it is all with same as the present application or close no matter doing any variation in its form or structure As technical solution, should all be within protection scope of the present invention.
