Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-3, an embodiment of the present invention provides a jack support structure for a fuel cell hydrogen energy automobile, including a threshold beam body 10 and a support body, where the support body is disposed at the bottom of each of two ends of the threshold beam body 10, the support body includes a bracket 20 and a pad 30, the bracket 20 is an aluminum profile structure, and is vertically disposed at the outer side of the bottom of the threshold beam body 10, and the side edge of the bracket is fixedly connected to the side edge corresponding to the threshold beam body 10, and the pad 30 is disposed at the lower end of the bracket 20 and detachably connected to the bracket 20.

In the present invention, the rocker body 10 is an existing structure, and the existing rocker structure of the hydrogen-powered vehicle can be used as an embodiment of the rocker body 10 of the present invention. The positions of the two ends of the threshold beam body 10 close to the end parts are provided with support bodies, so that the hydrogen energy automobile is provided with 4 support bodies in total. In order to facilitate the installation of the support body, the bracket 20 is fixed to the outer side of the bottom of the rocker beam body 10 by welding. The traditional mode of maintaining the automobile body is that external maintenance equipment directly acts on a threshold beam to jack or lift the automobile body, and acting force directly acts on the threshold beam of the automobile body, so that the threshold beam of the automobile body is stressed greatly, or a plurality of layers of high-strength stamping plates are welded on the threshold beam, and the acting force is transferred to the stamping plates.

In the above embodiment, the support 20 is composed of the upper connecting body 21 and the lower connecting body 22, the upper connecting body 21 and the lower connecting body 22 are both rectangular aluminum profile structures, and are distributed at intervals along the vertical direction and are arranged in an integrated manner, the two adjacent side edges of the upper connecting body 21 are respectively fixedly connected with the side edges of the corresponding side of the threshold beam body 10, and the cushion block 30 is arranged below the lower connecting body 22 and detachably connected with the lower connecting body 22.

In the utility model, the bracket 20 has the advantage of simple structure, and the bracket 20 with the aluminum profile structure can achieve the purpose of reducing weight and realizing the light weight of the vehicle body.

In the above embodiment, two claws 31 are arranged at the upper end of the cushion block 30, through holes corresponding to the two claws 31 are arranged on the bottom wall of the lower connecting body 22, the cushion block 30 is arranged below the lower connecting body 22, the claws 31 penetrate through the corresponding through holes to be clamped with the bottom wall of the lower connecting body 22, and the claws 31 are made of elastic materials.

In the utility model, the clamping detachable connecting structure facilitates the disassembly and assembly of the cushion block 30, and also has the advantages of good fixing effect, low implementation cost and the like. Specifically, the cushion block 30 is an inverted isosceles trapezoid structure, and in practical application, the cushion block can be designed into other geometric structures as needed. In order to ensure the fixing effect, the two claws 31 are symmetrically distributed along the central axis of the spacer 30. Because jack catch 31 is the elastic component, when it carries out the joint, need have a deformation space, consequently, in the below of jack catch, the recess that can supply jack catch 31 deformation is seted up to the upper end of cushion 30, is equipped with the annular groove in order to guarantee the upper end of cushion 30, and be equipped with rubber pad 32 in the annular groove, the up end of rubber pad 32 is located the below of annular groove up end, rubber pad 32 can play the effect of buffering.

In the above embodiment, the middle of the upper end of the cushion block 30 is provided with a limiting portion 33 having a cylindrical structure, the bottom wall of the lower connecting body 22 is provided with a limiting hole adapted to the limiting portion 33, and the limiting portion 33 of the cushion block 30 extends into the limiting hole.

In the present invention, the stopper 33 functions as a stopper to prevent the mounting accuracy of the spacer 30 and to prevent the spacer 30 from moving and falling off. The limiting part 33 is hollow inside and has an open upper end, so that the effects of reducing weight and reducing production cost are achieved. The limiting portion 33 and the cushion block 30 are integrally formed and are plastic pieces. In addition, the bottom of the spacer 30 is provided with a supporting groove 311, and an external device such as an external jack or a lifter acts on the supporting groove 311.
