Abstract
The utility model discloses a cascaded boss connection structure, it includes ladder boss mounting panel, ladder boss mounting panel central authorities have seted up and have prevented stress concentration and louvre, ladder boss assembly upper surface is provided with the cascaded structure of preventing extrusion that three is used for fastening upper end part, cascaded prevent that to link up on the extrusion structure has the fastening connection hole, be provided with the cascaded boss assembly on the fastening connection hole outer wall, the cascaded boss assembly is higher than cascaded prevent the extrusion structure, and exceeds the part and form semicircle ladder boss, semicircle ladder boss inner wall be the cambered surface and with fastening connection hole edge coincidence. The utility model discloses cascaded boss connection structure is moderate with sensor thickness, and the side can also play side limiting displacement, and center round hole effectively prevents stress concentration, and weight reduction can also effectively reduce cost, increases the air convection and the heat of fanning, still effectively prevents that the sensor from leading to unable heat of fanning to arouse the sensor damage because of generating heat that arouses in the use for a long time.
Description
Technical Field
The utility model relates to a dedicated sensor bridging device, concretely relates to cascaded boss connection structure.
Background
The LNG project is the latest six-country project, is a new vehicle model for updating, is used for seizing the market, guiding the industry direction, responding to the national energy conservation and emission reduction and realizing the green travel concept, and completely implements the Japanese daily product development design process, the vehicle model is a strategic vehicle model, the double shoulder mission of sales volume and profit is borne, in order to further achieve the first target of the quality industry, all special parts of the T17 vehicle model pass through CAE, and the design of both sides of ergonomics can achieve the three-party targets of safe and reliable quality, novel structure and lowest cost.
In order to achieve the reliability of quality and the improvement of efficiency, a step type boss connecting structure is developed in a brand-new way to be used for fixing easily damaged sensor equipment, so that the fixing requirement is met, and the sensor is effectively prevented from being damaged due to the fact that heating caused in the using process for a long time cannot be conducted to heat dissipation.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a stepped boss connecting structure; the structure is used for fixing the easily damaged sensor equipment, not only meets the fixing requirement, but also effectively prevents the easily damaged part of the sensor from being brittle and cracked due to fastening and pressurizing of threaded fastening, and therefore, the easily damaged part of the sensor is designed into a step state.
In order to realize the above-mentioned purpose, the utility model provides a cascaded boss connection structure, it includes ladder boss mounting panel, ladder boss mounting panel central authorities have seted up and have prevented stress concentration and louvre, ladder boss assembly upper surface is provided with the cascaded structure of preventing extrusion that three are used for fastening upper end part, cascaded structural having link up of preventing extrusion has the fastening connection hole, be provided with the cascaded boss assembly on the fastening connection hole outer wall, the cascaded boss assembly is higher than cascaded structure of preventing extrusion, and exceeds the part and form semicircle ladder boss, semicircle ladder boss inner wall be the cambered surface and with fastening connection hole edge coincidence.
Furthermore, a plurality of connecting through holes for fixing are formed in the arc angle of the edge of the stepped boss mounting plate.
Still further, the number of the connecting through holes is 3.
The utility model has the advantages that:
the utility model discloses cascaded boss connection structure is moderate with sensor thickness, and the side can also play side limiting displacement, and center round hole effectively prevents stress concentration, and weight reduction can also effectively reduce cost, increases the air convection and the heat of fanning, still effectively prevents that the sensor from leading to unable heat of fanning to arouse the sensor damage because of generating heat that arouses in the use for a long time.
The utility model discloses reduce the cost, weight reduction, the fan is hot, prevents stress concentration, prevents extrusion deformation.
