Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the structure is mainly composed of the following parts: the front floor passage 4, the front floor passage reinforcement 1, the "Z" shaped hook 2 and the annular retaining ring 3.
[0018] The front floor tunnel 4 is a general structure on which the front floor tunnel reinforcement 1 is welded. The shape of the front floor channel reinforcement 1 is a double "several" shape, that is, as Figure 4 The transverse section shown is an inverted "ji"-shaped structure, Figure 5 The longitudinal section shown is a positive "Ji"-shaped structure.
[0019] Such as figure 2 As shown, the left flange of the transverse inverted "J"-shaped structure of the front floor passage reinforcement 1 is welded to the overlapping surfaces 51, 52 of the front floor left longitudinal beam 5, and the right flange is welded to the front floor right longitu...

The invention provides a strengthening structure of an automobile front floor passage. The strengthening structure of the automobile front floor passage comprises a front floor passage and a front floor passage strengthening piece, wherein the transverse section of the front floor passage strengthening piece is shaped like an inverted Chinese character 'ji'; the left side face and the right side face of the structure in the shape of the inverted Chinese character 'ji' are welded with a corresponding profile of the front floor passage respectively; flanges of the left side face and the right side face are welded with a front floor left longitudinal beam and a front floor right longitudinal beam respectively; the longitudinal section of the front floor passage strengthening piece is in a structure shaped like a regular Chinese character 'ji'; a front side flange and a right side flange of the structure shaped like the regular Chinese character 'ji' are welded with the bottom plane of the front floor passage respectively; gear shift operating mechanism installation points are arranged on the flanges; a cavity is formed between the top face of the structure shaped like the regular Chinese character 'ji' and the bottom plane of the front floor passage; and silencer insulation board installation points are arranged on the top face of the structure shaped like the e regular Chinese character 'ji'. With the adoption of the strengthening structure of the automobile front floor passage, the strength of the front floor passage can be enhanced; moreover, installation support is provided for a gear shift operating mechanism and a silencer assembly respectively; and therefore, the safety and the riding comfortableness of an automobile are improved.
Description
technical field [0001] The invention belongs to the vehicle front floor structure technology, and in particular relates to a vehicle front floor channel reinforcement structure. Background technique [0002] The existing front floor passages are generally reinforced by reinforcements, but the reinforcements only play a structural strengthening role for the front floor passages, and do not undertake other installation functions. Therefore, the structure is relatively simple. This structural feature is that many body parts are directly installed on the front floor tunnel body, which increases the load on the front floor tunnel body, resulting in a complex structure of the front floor tunnel body, which is easily affected by other body parts, thereby reducing the comfort of the vehicle sex. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention proposes a reinforcement structure for the front floor passage of the a...
