UTILITY MODEL CONTENT

[0003] In view of the deficiencies of prior art, the main purpose of the utility model is to provide a new energy automobile power system test liftable platform that is convenient to adjust and stably lifts.

[0004] In order to achieve the above object, the utility model provides the following technical scheme: a new energy automobile power system test liftable platform, including base, fixed frame body and the lifting assembly arranged in fixed frame body, the lifting assembly includes the screw rod vertically arranged in fixed frame body, the bottom of screw rod is rotatably connected with the bottom of fixed frame body, the upper portion of screw rod is connected with bearing seat through the top plate of fixed frame body, the top of screw rod is fixedly connected with rocker, the screw rod is screw connected with the threaded sleeve, the threaded sleeve is fixedly arranged on lifting block, the fixed frame body is also provided with the balance bar through the lifting block on the both sides of screw rod, the lifting block is fixedly connected with the support plate, the side surface of fixed frame body is welded with the pointing piece, the pointing piece is vertically provided with a plurality of alignment holes, the side surface of lifting block is provided with the fixed hole in the same vertical line with the plurality of alignment holes, the fixed hole can insert the pin shaft.

[0005] Preferably, the front cover capable of shielding the lifting assembly is fixedly arranged on the base.

[0006] Preferably, the connecting part of the pointing piece and the fixed frame body is a plurality of bent end angles, the plurality of bent end angles are arranged at equal intervals, and the plurality of bent end angles are spot welded with the fixed frame body.

[0007] Preferably, a plurality of waist-shaped fixed holes are arranged on the support plate.

[0008] This invention has the following advantages over existing technologies: When supporting a motor or power battery, several liftable platforms of this design can be used together to support different positions of the product to be tested, and the height of the support plate can be adjusted accordingly. When a single platform is in use, a rocker arm drives a screw to rotate, which in turn drives a threaded sleeve and a lifting block connected to the threaded sleeve to move up and down, thereby moving the lifting plate and the product to be tested on the lifting plate up and down. The fixed frame also has balance bars passing through the lifting blocks on both sides of the screw, which improves the stability of the lifting block and support plate during lifting. A guide plate is welded to the side of the fixed frame, and several alignment holes are vertically arranged on the guide plate. The side of the lifting block has a fixing hole located on the same vertical line as the alignment holes, into which a pin can be inserted. This design reduces the pressure on the threaded structure and improves the stability of the lifting plate, providing an extra layer of protection. Attached Figure Description
