Technical Field
The utility model relates to a bolt fastening technical field especially relates to a bolt mounting structure for roof battery.
Background
In the prior art, the structure adopting bolt fixing generally comprises the steps of firstly punching, then placing a bolt to the punched hole, and finally screwing a nut to fix the bolt.
However, in some special use scenarios, such as new energy buses and the like, the battery pack needs to be installed and fixed at the roof, and the battery pack is usually fixed by bolts, but if the battery pack is directly fixed by bolts through punching, the battery pack is large in mass, and the bolt connection part is large in stress and easy to loosen, so that the battery pack shakes during the driving process, and even the risk that the battery pack falls off occurs.
The reason for this is that the battery pack tends to slip back and forth relative to the roof surface during acceleration or deceleration of the vehicle, and the screw of the bolt is fixed perpendicular to the roof surface, so the main stressed component is the nut of the bolt; and because the contact area between the screw cap and the surface of the car roof is very small, the unit area of the car roof is very stressed, the screw cap is easy to deform under the driving of the battery pack, and further, the bolt connection part is loosened, so that a series of dangers occur.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Referring to fig. 1, the utility model discloses a bolt mounting structure for roof battery, include:
an embedded plate 300 fixed to the roof 200;
a mounting plate 400 fixed to a side of the embedment plate 300 away from the roof 200;
mounting bolt 100, comprising: the bolt 110 sequentially penetrates through the mounting plate 400, the embedded plate 300 and the roof 200, at least part of the bolt 110 extends out of the roof 200, the head 120 is fixedly connected with the mounting plate 400, and the adjacent space of the head 120 is filled with sealant 600.
In this embodiment, the mounting plate 400 is additionally installed and welded to the head 120, so that the head 120 of the bolt and the mounting plate 400 form a whole, and the part of the screw 110 extending out of the roof 200 is used for fixing the battery pack. When the battery pack has a tendency to slide relative to the surface of the roof 200 as the automobile runs, the screw 110 is stressed to transmit the tendency to the head 120, and the head 120 with the mounting plate 400 abuts against the embedded plate 300 and simultaneously relieves the force, so that the strength of the bolt connection is protected. Furthermore, because the contact area between the mounting plate 400 and the embedded plate 300 is large enough, even under the condition of rapid acceleration or rapid deceleration of the automobile, namely when the tendency of battery pack slippage is large, the force for causing the battery pack slippage can be removed by the abutting of the mounting plate 400 and the embedded plate 300, and the stress between the mounting plate 400 and the embedded plate 300 in unit area is small. Therefore, the mounting plate 400 and the embedded plate 300 can also protect the roof 200 from deformation, prolong the service life of the roof 200 and enhance the safety of the battery pack of the roof 200.
The adjacent space described here refers to the surrounding space of the head 120, including the peripheral side space of the head 120, the head space of the head 120, and a gap that may exist between the head 120 and the mounting plate 400, and the like. The sealant 600 is filled to enhance the corrosion resistance and the like of the bolt and to prolong the service life thereof.
A plurality of rivets 500 penetrate between the mounting plate 400 and the embedded plate 300, and the rivets 500 are perpendicular to the mounting plate 400 or/and the embedded plate 300.
The rivet 500 is arranged to penetrate through the mounting plate 400 and the embedded plate 300, so that relative rotation between the mounting plate 400 and the embedded plate 300 can be prevented, and meanwhile, the connection strength between the mounting plate 400 and the embedded plate 300 is enhanced, so that greater force can be removed when the mounting plate 400 and the embedded plate 300 are abutted against each other, and the bolt mounting strength is further protected.
Further, the mounting plate 400 and the embedded plate 300 are fixed by the rivets 500, so that field welding of the mounting plate 400 and the embedded plate 300 is avoided, the working efficiency is improved, and the difficulty of field operation is reduced.
The roof 200 is provided with a plurality of rivet holes 210, and the rivets 500 enter from the rivet holes 210 and sequentially pass through the embedded plate 300 and the mounting plate 400.
The rivet hole 210 is filled with a sealant 600.
The effect of the sealant 600 filled in the rivet hole 210 is to prevent rainwater from flowing into the vehicle from the rivet hole 210, and also to prevent the rivet 500 from rusting and corroding.
The vehicle roof 200 and the pre-buried plate 300 are welded and fixed, and a sealant 600 is filled between the vehicle roof 200 and the pre-buried plate 300.
And a sealant 600 is filled between the embedded plate 300 and the mounting plate 400.
The specific implementation steps and the working principle of the embodiment are as follows:
firstly, welding the mounting plate 400 and the mounting bolts 100, simultaneously sinking the rivets 500 into the embedded plate 300, then welding and fixing the mounting plate 400 and the embedded plate 300, meanwhile, a plurality of rivets 500 penetrate through the mounting plate 400, the screw rods 110 of the mounting bolts 100 sequentially penetrate through the embedded plate 300 and the vehicle roof 200 from bottom to top, and the screw rods 110 extend out of the vehicle roof 200 to be used for fixing the battery pack. After the installation, the battery pack may have a tendency to slip around, in the driving process of the automobile, so that the screw 110 may have a tendency to tilt, and the head 120 together with the mounting plate 400 abuts against the embedded plate 300, and finally the force is removed. Therefore, the roof 200 is protected from deformation, and a series of dangerous accidents that the bolt connection part is loosened, the roof 200 deforms, the battery pack is exposed and even falls off and the like due to the fact that the head 120 is directly abutted against the roof 200 under the inclined driving of the screw 110 are avoided.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
