Description

Electric workbench for bicycle maintenance}

The present invention relates to a workbench for bicycle maintenance, and more particularly, to increase the efficiency of bicycle maintenance work by automatically lifting various bicycles with different specifications and loads in various heights and shapes, and in the process of bicycle maintenance. The present invention relates to an electric workbench for bicycle maintenance that can increase the safety of maintenance work by preventing accidents such as falling of a bicycle while being lifted.

A bicycle is one of the means of transportation on land.

Since the bicycle can move more quickly than walking, it is not only used as a means of short-distance transportation, but also can be used as a means of exercise because the exercise effect is considerable as the muscles of various parts of the body are stimulated during the process of pedaling. Recently, the number of users is increasing rapidly.

Meanwhile, since a bicycle is composed of a plurality of parts, stable driving can be achieved when each part operates smoothly.

For this reason, cyclists frequently repair their bicycles, and if self-maintenance is difficult, they visit specialized shops to repair their bicycles.

At this time, some of the parts constituting the bicycle are not only small but also have a complicated structure, so it is necessary to check them closely and maintain them.

For this reason, various 'work benches for bicycle maintenance' as disclosed in Korean Patent Publication No. 10-2014-0022279 have been proposed.

A bicycle maintenance workbench can lift a bicycle that requires maintenance. For example, as the bicycle is lifted to the operator's eye level, each part can be viewed closely in a more comfortable position, so that the maintenance of the parts can be performed more accurately and easily. can

However, since most of the conventional bicycle maintenance workbenches manually lift maintenance target bicycles, it is difficult to lift large and heavy bicycles, such as electric bicycles and pet bikes, compared to general bicycles.

In addition, since most of the conventional bicycle maintenance workbenches can only lift a bicycle to be serviced in one form, the movement of the operator is required depending on the location of the part, which causes considerable inconvenience in the maintenance process.

In addition, in the case of a conventional bicycle maintenance workbench, accidents such as falling often occurred while lifting a bicycle, resulting in human and material damage due to accidents.

For the above reasons, it is possible to automatically lift various types of bicycles with different specifications and loads in various heights and shapes in the relevant field, thereby increasing the efficiency of bicycle maintenance work, as well as preventing accidents such as falling bicycles while lifting during the bicycle maintenance process. Attempts are being made to develop a bicycle maintenance workbench that can increase the safety of maintenance work by preventing the problem, but satisfactory results have not been obtained so far.
