Automotive electric ascending and descending table

Abstract

The invention belongs to the field of vehicle parts and particularly relates to an automotive electric ascending and descending table which can slide on a guide rail and can automatically ascend and descend. The automotive electric ascending and descending table comprises the guide rail and a control device, wherein the guide rail is connected to an automobile; a slidable table body is connected to the guide rail and comprises a base which is connected with the guide rail; a guide column capable of ascending and descending is connected to the base and comprises an internal guide column and an external guide column; the internal guide column is fixedly connected to the base; the external guide column is arranged outside the internal guide column and can vertically ascend and descend; the top of the external guide column is connected with a workbench; a power device is arranged on the base and is connected with a transmission mechanism which drives the guide column to vertically ascend and descend; the control device is arranged inside the ascending and descending table and is connected with the power device through a wire. According to the automotive electric ascending and descending table, the guide column is driven by a direct current motor or a stepping motor to ascend and descend; the workbench can be electrically controlled to ascend and descend; the total ascending and descending process can be controlled. The automotive electric ascending and descending table is higher in stability.

Description

technical field [0001] The invention belongs to the field of vehicle components, and in particular relates to an automobile electric lifting table which can slide on guide rails and can be automatically lifted. Background technique [0002] The lift tables in the existing automobiles generally use cylinders as the power to lift the lift table, and there are the following problems in using the cylinders as the power: 1. During the rising process, the lifting height and speed of the cylinder are uncontrollable, and there is a safety hazard if the speed is uncontrollable. Hidden danger, in order to adjust the lifting height, it is necessary to add a limit structure on the guide post, which increases the structural complexity of the guide post and is not convenient for production. 2. The bearing capacity of the cylinder is limited. After placing items on the table, the lifting height of the cylinder is easy Changes occur, and after a little artificial pressure is applied, the st...

[0002] The lift tables in the existing automobiles generally use cylinders as the power to lift the lift table, and there are the following problems in using the cylinders as the power: 1. During the rising process, the lifting height and speed of the cylinder are uncontrollable, and there is a safety hazard if the speed is uncontrollable. Hidden danger, in order to adjust the lifting height, it is necessary to add a limit structure on the guide post, which increases the structural complexity of the guide post and is not convenient for production. 2. The bearing capacity of the cylinder is limited. After placing items on the table, the lifting height of the cylinder is easy Changes, and after a little artificial pressure, the stability of the desktop is poor. 3. During the process of retracting the cylinder, manual pressure is required to retract it, which is inconvenient for some users with less strength.
