Abstract
The utility model discloses an auto ground structure, which comprises a fastening nut (1), a mounting hole (2) and a ground screw stud (5), wherein one end of the ground screw stud (5) is connected with a support frame (7) of the auto body in a projection welding manner after penetrating the mounting hole (2); and a sealing protecting sleeve (4) is arranged at the other end of the ground screw stud (5) and connected with the ground screw stud (5) in a threaded manner. The auto ground structure solves the problems such as bad sealing effect and low NVH (Noise Vibration and Harshness) effect of the integral auto caused by using the bolt to fasten the ground and the auto body; and meanwhile, by using the sealing protecting sleeve, the problem of high ground resistance caused by high probability of paint entering is solved. The auto ground structure has a simple structure and is easy to realize.
Description
Technical field
The utility model relates to a kind of automobile bonding structure.
Background technology
At present; the automobile bonding has dual mode; as shown in Figures 1 to 4; Fig. 1 to Fig. 2 is the bonding mode of first kind of structure; its structure is a welding projection welding nut on vehicle body, and the bolt of screwing on before entering application workshop protection is at assembly shop bolt wire harness bonding terminal; the advantage of this mode is that screw-down torque is big, fixation.Fig. 3 to Fig. 4 is the bonding mode of second kind of structure, its structure is planted the weldering bolt for welding on vehicle body, and the nut sleeve of screwing on before entering application workshop protection is at assembly shop nut fixed beam bonding terminal, the advantage of this mode is to plant the weldering bolt through anti-corrosion treatment, and is not perishable; Nut sleeve and bolt seal are respond well, but there is following shortcoming respectively in above-mentioned two kinds of bonding modes:
First kind of bonding mode:
1, it is bad that bolt and vehicle body are tightened the face sealing effect, and paint enters easily thereby causes the bonding contact resistance big during coating process;
2, need punch on vehicle body, it is poor that bonding and vehicle body are tightened sealing effectiveness with bolt, causes car load NVH effect to reduce;
3, vehicle body sealing place is without protection, and is perishable.
Second kind of bonding mode:
1, when current consumer power is big, when needing to use bigger Tightening moment fastening nut, plants the weldering bolt and easily come off.
The utility model content
Problem to be solved in the utility model provides a kind of automobile bonding structure, and its purpose improves car load NVH effect, prevents that paint enters easily and causes the bonding contact resistance big when coating process.
To achieve these goals, the technical scheme taked of the utility model is:
This automobile bonding structure provided by the utility model, comprise clamp nut, mounting hole, bonding double-screw bolt, described bonding double-screw bolt one end passes described mounting hole and is connected with the body support projection welding, the other end of described bonding double-screw bolt is provided with sealing sheath, and described sealing sheath is threaded with the bonding double-screw bolt.
Described body support is connected with automobile body welding.
Described bonding double-screw bolt is planted weldering with Wiring harness terminal and is connected.
One end of described clamp nut and bonding double-screw bolt is fastenedly connected.
Adopt technique scheme, this automobile bonding structure, adopt projection welding to be connected with bolted, having solved bonding and vehicle body, to tighten sealing effectiveness with bolt poor, the problem that causes car load NVH effect to reduce, paint enters easily thereby causes the big problem of bonding contact resistance when using sealing sheath to solve coating process simultaneously, and is simple in structure, is easy to realize.

The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 5 to 6, this is a kind of automobile bonding structure, comprises clamp nut 1, mounting hole 2, bonding double-screw bolt 5.
In order to solve the problem that exists at the described present known technology of this specification sheets background technology part and to overcome its defective, realize improving car load NVH effect, prevent that paint enters easily and causes the bonding contact resistance big when coating process.The technical scheme that the utility model is taked is:
Extremely shown in Figure 6 as Fig. 5, this automobile bonding structure provided by the utility model, described bonding double-screw bolt 5 one ends pass described mounting hole 2 and are connected with body support 7 projection weldings, and the other end of described bonding double-screw bolt 5 is provided with sealing sheath 4, and described sealing sheath 4 is threaded with bonding double-screw bolt 5.
Described body support 7 is welded to connect with vehicle body 6.
Adopt technique scheme, one end of bonding double-screw bolt 5 passes described mounting hole 2 and is connected with body support 7 projection weldings, solved the perforate on vehicle body of first kind of scheme in background technology, thereby the problem that causes car load NVH effect to descend, use projection welding to be connected with bolted, solved the problem that double-screw bolt comes off under the big moment, the other end at bonding double-screw bolt 5 is provided with sealing sheath, described sealing sheath 4 is threaded with the bonding double-screw bolt, has solved to paint when entering coating process to enter and the big problem of bonding contact resistance in morning easily.
To shown in Figure 6, described bonding double-screw bolt 5 is planted weldering with Wiring harness terminal and is connected as Fig. 5.
Adopt technique scheme, described bonding double-screw bolt 5 is planted weldering with Wiring harness terminal and is connected, and prevents 5 corrosion of bonding double-screw bolt like this.
To shown in Figure 6, described clamp nut 1 is fastenedly connected with an end of bonding double-screw bolt 5 as Fig. 5.
Adopt technique scheme, described clamp nut 1 is fastenedly connected with an end of bonding double-screw bolt 5, has solved the problem that the bonding double-screw bolt comes off under the big moment.
