Description

Buffering support structure

Technical Field

The utility model belongs to the technical field of automobile parts and relates to a buffer support structure.

Background

When the engine cover is closed and the vehicle runs, especially when the vehicle runs on a bumpy road, because the strength of the contact surface of the buffer block is insufficient, the contact surface of the buffer block is often deformed, so that the matching of the buffer block and the engine cover inner plate is influenced, gaps and surface differences between the engine cover and peripheral parts are caused, and the appearance quality of the vehicle is influenced, for example, Chinese patent document (application number: 201520098305.0) discloses a reinforcing structure of the contact surface of the engine cover inner plate and the buffer block and the engine cover, and the reinforcing structure comprises: the buffer block is arranged on at least one engine cover on the edge beam of the water tank cross beam; a bonnet inner panel comprising: a bonnet inner panel body and at least one reinforcement located on the bonnet inner panel body; when the engine cover is in a closed state, the reinforcing part is contacted with the buffer block; the buffer block is of a cylindrical structure, and the outer side of the cylindrical structure comprises a plurality of spiral grains. Although the reinforcing structure of the contact surface between the inner engine cover plate and the buffer block and the engine cover improve the condition of uneven gaps and surface differences between the engine cover and the peripheral parts caused by running on a bumpy road, the reinforcing structure has the following defects: because the buffer block direct mount leads to pedestrian's protection test to pass through on the water tank crossbeam boundary beam, in addition, because the required installation space of this structure is great, also can't be applicable to bonnet rear end both sides region, so this structure can't be applied to present motorcycle type.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a buffer bracket structure. The utility model solves the technical problem of how to better ensure the gap surface difference uniformity of the inner plate of the engine cover and peripheral parts.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a buffering supporting structure, its characterized in that is including being used for installing the buffer block on the bonnet inner panel and being used for installing the support on the engine compartment side wall, is provided with the nut on the support, and threaded connection has self-tapping bolt on the nut, and self-tapping bolt's top is provided with the blotter, and when the bonnet inner panel was in the closure state, the bottom surface of buffer block and self-tapping bolt's top surface contact.

This buffering support structure's bonnet inner panel is when the closure, the bottom surface of buffer block and self-tapping bolt's top surface contact, self-tapping bolt threaded connection can adjust the upper and lower position of self-tapping bolt on the nut through rotatory self-tapping bolt on being located the nut of support for self-tapping bolt has certain altitude mixture control volume, thereby can compensate the bonnet inner panel because the terminal deformation that self rigidity leads to, guarantees that the bonnet inner panel is poor even with the clearance face of peripheral part.

In the above-mentioned buffer bracket structure, a cushion pad is provided on the top of the self-tapping bolt, and when the bonnet inner panel is in a closed state, the bottom surface of the cushion block contacts with the top surface of the cushion pad. The blotter setting is at self-tapping bolt's top, and when the bonnet inner panel was in the closure state, the bottom surface of buffer block and the top surface contact of blotter for buffering effect is better.

In foretell buffering support structure, the mounting hole has been seted up on the bonnet inner panel, the top of buffer block is provided with the joint groove that is used for being connected with the border joint of mounting hole. Because the buffer block is installed on the mounting hole of bonnet inner panel through the border joint connection of joint groove and mounting hole, can adopt the mode of back installation to reduce the fashioned degree of difficulty of bonnet inner panel.

In the above-mentioned buffering support structure, the top edge of the buffering block is upwards formed with a protruding part for forming interference fit contact with the inner plate of the engine cover, and the protruding part is located on the outer peripheral side of the clamping groove.

The back is connected through the border joint of joint groove and mounting hole to the buffer block, and the bellying makes the joint groove of buffer block inseparabler with the border joint of mounting hole, avoids having the clearance behind the border joint of joint groove and mounting hole and leads to the buffer block to install the back to exist and rock and influence the buffering effect of buffer block.

In the above buffer support structure, the top of the support is platform-shaped and is provided with a through hole, the nut is welded and fixed on the inner side of the top of the support, and the self-tapping bolt penetrates through the through hole and is fixed with the nut.

Nut welded fastening is in the inboard at support top, and self-tapping bolt passes behind the through-hole and is fixed mutually with the nut, can guarantee self-tapping bolt's stability, avoids self-tapping bolt to have the intensity poor when cooperating with the buffer block simultaneously, and the contact of self-tapping bolt and support can be avoided to the through-hole to the convenience is adjusted self-tapping bolt and buffer block's matching through rotatory self-tapping bolt.

In the above-mentioned buffering support structure, the installation cavity has been seted up at self-tapping bolt's top, the blotter inlays to be established in the installation cavity and the top of blotter protrudes the installation cavity. So that the cushion pad is more firmly disposed on the top of the tapping bolt.

In the above-mentioned buffering support structure, the upper and lower both ends of the support are respectively provided with a fixed part for welding and fixing with the engine compartment side wall. The support has two fixed parts that are used for welded fastening, promotes the firmness of support welding at the engine compartment side wall and strengthens the support rigidity of support, guarantees the steadiness of blotter.

In the above-mentioned buffering support structure, the support is provided with a reinforcing rib, and the reinforcing rib is located between the fixing portion and the top of the support. The strengthening rib can strengthen the intensity and the support rigidity of support, guarantees the steadiness of blotter.

In the above-mentioned buffering support structure, the bottom surface of the buffering block is a plane, and the top surface of the buffering pad is a plane. When the inner plate of the engine cover is in a closed state, the contact effect of the buffer block and the buffer pad is better.

Compared with the prior art, this buffering supporting structure's advantage lies in: this buffering support structure's bonnet inner panel is when the closure state, the bottom surface of buffer block and the top surface contact of blotter, the blotter setting is at self-tapping bolt's top, self-tapping bolt threaded connection is on being located the nut of support, can adjust the upper and lower position of self-tapping bolt on the nut through rotatory self-tapping bolt for the blotter has certain altitude mixture control volume, thereby can compensate the bonnet inner panel because the terminal deformation that self rigidity leads to, guarantee the clearance face difference uniformity of bonnet inner panel and peripheral part.
