Description

TECHNICAL FIELD

[0001] The utility model relates to a steering column for supporting a steering wheel on a traffic driving tool, in particular to a steering column height adjusting structure capable of adjusting the extension height of the steering column. BACKGROUND

[0002] Traffic driving tools on the market, such as electric vehicles or golf carts used in various communities, have a rotating shaft of a steering column supporting a steering wheel arranged on a driving platform. A push rod device for supporting is installed on the steering column. When a user needs to adjust the extension height of the steering column, the push rod device is generally manually extended or retracted to extend or shorten the steering column. This method not only requires the user to exert a large amount of force, but also requires the protective sleeve made of soft rubber to be designed large enough to wrap the steering column and the push rod device. In addition, the driving platform needs to have a large enough opening to provide sufficient space for the steering column and the push rod device. This results in the need to reserve a large space at the driving seat, and the oversized protective sleeve is prone to aging over time, causing gaps between the protective sleeve and the steering column or the opening of the driving platform, which affects the dust blocking effect and affects the work of the electronic instruments in the driving platform. SUMMARY

[0003] The steering column height adjusting structure provided by the utility model directly controls the extension and retraction of the electric push rod by pressing the push rod switch, thereby achieving the extension and retraction of the steering column. This not only makes the extension and retraction operation of the steering column simple and fast, but also allows the protective sleeve to be designed smaller when the electric push rod is installed in the driving platform, which only needs to be the size of the steering column. This makes the protective sleeve more effective in blocking dust.

[0004] The technical solution provided by the utility model is a steering column height adjusting structure, which includes a steering column and a driving platform. The steering column is installed on the driving platform. A protective sleeve is wrapped between the steering column and the driving platform. The driving platform is fixed with a steering bracket. The steering bracket is provided with a fulcrum hole one and a fulcrum hole two. The steering column is provided with a column hole one and a column hole two. The column hole one is hingedly connected with an electric push rod. The other end of the electric push rod is hingedly connected with the fulcrum hole one. The fulcrum hole two is hingedly connected with the column hole two.

[0005] Preferably, the driving platform is provided with a sleeve turning hole, and the protective sleeve is provided with a sleeve turning column. The sleeve turning column is movably installed in the sleeve turning hole.

[0006] Preferably, the electric push rod is arranged on one side of the steering column. An auxiliary push rod is installed on the side of the steering column opposite to the side where the electric push rod is arranged. The auxiliary push rod and the electric push rod are in a position parallel relationship.

[0007] Preferably, the driver's stand is further provided with a push rod switch, and the push rod switch is electrically connected with the electric push rod.

[0008] Compared with the prior art, the electric push rod is used to push the steering column, so that the user can accurately adjust the length of the steering column by pressing the push rod switch, and the user's driving habit is more suitable. BRIEF DESCRIPTION OF DRAWINGS

[0018] The utility model will be further explained in detail below with reference to the drawings.

[0019] Referring to Figures 1-8 The steering column height adjusting structure of the utility model, steering column 1 is installed on the driver's stand 2, the steering column 1 is sleeved with the protective sleeve 3 between the driver's stand 2, it is characterized in that, the driver's stand 2 is equipped with the bogie 22, the steering column 1 is hingedly connected with electric push rod 4, the other end of electric push rod 4 is hingedly connected with the bogie 5.

[0020] Although Figure 2 The driver's stand 2 and the bogie 5 do not have any connection relation in the middle, but the driver's stand 2 and the bogie 5 are fixedly installed in the frame in actual use, that is, by the fixed connection relation with the frame, the driver's stand 2 and the bogie 5 form a fixed relation.

[0021] The lower end of electric push rod 4 and the lower end of steering column 1 are hingedly connected with the bogie 5, so that when electric push rod 4 works and its push rod elongates and shortens, the connection place of electric push rod 4 and steering column 1 will be the force action point to directly push steering column 1 to elongate and shorten,

[0022] When the user uses the utility model to adjust the extension length of steering column 1, presses the extension key of push rod switch 23, push rod switch 23 controls electric push rod 4 to extend, the lower end of electric push rod 4 cannot push the fixed bogie 5, so that electric push rod 4 directly pushes steering column 1, the lower end of steering column 1 cannot push the bogie 5, so steering column 1 will be pushed out by the elongation movement of electric push rod 4. At this time, the upward extension of steering column 1 will make the protective sleeve 3 sleeved on steering column 1 rotate upward with sleeve rotating hole 21 as the rotation center.

[0023] The above-mentioned is only the preferred implementation of the utility model, it should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the creative concept of the utility model, can make several deformation and improvement, these all belong to the protection scope of the utility model.
