Connection structure of frame front pillar, front beam and longitudinal beam of three-dimensional garage

Abstract

The invention discloses a connection structure of a frame front pillar, a front beam and a longitudinal beam of a three-dimensional garage, which comprises the front pillar, the front beam and the longitudinal beam which are vertical to one another pairwise and is characterized by also comprising a first connector and a second connector, wherein a first through hole is formed on the circumferential face of a first boss, a first mounting hole is formed on the front beam, and a first fastener is inserted into the first through hole and the first mounting hole; a second through hole is formed onthe circumferential face of the first boss, a second mounting hole is formed on the front beam, and a second fastener is inserted into a second connection hole, the second through hole and the secondmounting hole; a third through hole is formed on the circumferential face of a second boss, a third mounting hole is formed on the longitudinal beam, and a third fastener is inserted into the third through hole and the third mounting hole; and a fourth through hole is formed on the circumferential face of the second boss, a fourth mounting hole is formed on the longitudinal beam, and a fourth fastener is inserted into the fourth through hole and the fourth mounting hole. Compared with the prior art, the connection structure is convenient to assemble and high in connection precision; and the first and second connectors are fixed in two directions respectively to control the deformation of connection parts in two degree-of-freedom directions and guarantee the operation accuracy and use safety of the garage.

Description

technical field [0001] The invention relates to a connection device, in particular to a connection device between the front upright post of the vehicle frame, the front cross beam and the longitudinal beam used in the three-dimensional garage. Background technique [0002] With the development of society, the number of personal cars in cities is increasing day by day. In order to solve the contradiction between the area occupied by parking spaces and the commercial area of ​​residents, three-dimensional mechanical parking equipment has begun to be used by more and more people because of its unique characteristics of small average area of ​​bicycles. accepted by users. [0003] Generally, the main body of a common three-dimensional garage is mostly a three-dimensional vehicle frame with a multi-layer structure. The vehicle frame is a frame structure and usually includes a plurality of parallel and vertically arranged front Rear columns arranged vertically, front beams arrang...

AI Technical Summary

Problems solved by technology

In order to realize the fixed connection between the front column, the front beam and the longitudinal beam, and the fixed connection between the rear column, the rear crosspiece and the longitudinal beam, in the prior art, the connecting surface of the column and the beam is directly passed through a pin. Positioning or screw fastening connection, although this connection method is simple to operate and convenient to construct, but because the columns and beams are arranged perpendicular to each other, the contact area of ​​the connection surface is limited, and the connection accuracy of the direct connection with pins or screws is low, and the connection strength and The connection rigidity is poor, which will affect the connection reliability and safety of the three-dimensional garage, and will also affect the running accuracy and service life of the three-dimensional garage
