Description

Locomotive control structure

The present invention relates to a locomotive control structure, in particular to a locomotive control structure suitable for adjustable wheel base.

In the prior art, the suspension assembly of the traditional locomotive structure is directly connected to the suspension arm with elastic elements. The suspension arm is connected to the wheel and the frame with a fixed element. Therefore, in the locomotive under this traditional structure, the axle The distance cannot be adjusted flexibly, so the shape change or volume of the locomotive structure cannot be changed, which is easily limited by the inconvenience of garage space and transportation.

Because of this, the inventor, based on the spirit of active invention, eagerly thought of a locomotive control structure that could solve the above-mentioned problems, and finally completed the present invention after several research experiments.

The main purpose of the present invention is to provide a locomotive control structure, which can control a buckling member to be buckled and connected to the support rod, or the buckle member is separated from the connection support rod, so that the suspension group can be adjusted to an unfolded state according to the situation Or a folded state to achieve the purpose of the invention of the telescopic wheelbase. Among them, after shortening the wheelbase, the car body can be easily placed in a limited space and can be easily moved to each floor, which improves the convenience of the rider when carrying it.

In order to achieve the above objective, the locomotive control structure of the present invention is arranged on a frame to control the position of a suspension group. The frame has a first positioning point, a second positioning point and a fixed shaft. The suspension group includes a connecting support rod, a suspension arm and a shock absorber. The connecting support rod is pivoted on the frame with a first shaft, and the suspension arm is pivoted on the connecting support rod with a second shaft. , The shock absorber connects the support rod and the suspension arm.

The locomotive control structure includes a driving arm, a crank arm and a buckling member. The driving arm has a guide groove and is pivoted on the fixed shaft of the frame; the crank arm includes a starting part and a driving part. The starting part is pivoted on the frame for the rider to operate and adjust, and the driving part is slidingly arranged In the guide groove, it is used to drive the driving arm to act synchronously; the buckle member is arranged on the driving arm to buckle or detach the connecting support rod to adjust the position of the suspension group and the rear wheel.

Among them, when the suspension group is in an unfolded state, the buckling member can be buckled and connected to the support rod at the first positioning point for the rider to ride; if the suspension group is to be converted to a folded state, the riding The rider can rotate the starting part of the crank arm to make the driving arm and the buckling member rotate synchronously, and then the buckling member is separated from the connecting support rod, and finally the suspension arm is buckled to the second positioning point for the rider to carry and collapse.

With the above design, the buckling member can be selectively buckled or disengaged from the connecting support rod to adjust the position of the suspension group and the rear wheel, so as to achieve the purpose of the invention of telescopic wheelbase. This mechanism has the advantages of convenient operation, space saving and convenient traction of the locomotive, and the convenience of carrying by the rider.

The starting part may further include a handle to facilitate the rider to rotate the crank arm. Thereby, when the rider wants to adjust the position of the suspension group and the rear wheel, the crank arm can be rotated by operating the handle to improve the operability in use.

The above-mentioned driving arm may further include a fixing pin, and the fastening member may be pivoted on the fixing pin. Thereby, the fastening members can be individually pivoted and actuated to buckle or disengage the connecting support rod, and adjust the position of the suspension group and the rear wheel.

The above-mentioned fastening member may further include a spring to provide a resilient force of the fastening member. Thereby, when the buckling member contacts the connecting support rod, the resilient force of the spring can be used to tightly buckle the connecting support rod after being opened for a short period of time, so as to surely keep the suspension assembly in an unfolded state.

The above summary and the following detailed description are exemplary in nature to further illustrate the scope of patent application of the present invention. The other objectives and advantages of the present invention will be described in the following description and drawings.

The figure shows a locomotive structure with locomotive control structure 1, mainly including a locomotive control structure 1, a frame 2, a suspension group 3, a first shaft 41 and a second shaft 42, mainly used to adjust the rear wheels The position of 8 allows the wheelbase to be flexibly adjusted to form an unfolded state and a folded state.

In this embodiment, the frame 2 is the main structure of the vehicle, and has a first positioning point 21 and a second positioning point 22, which can be used for positioning cards of the suspension group 3 and the frame 2 in different states. Buckle use.

Secondly, the suspension group 3 includes a connecting support rod 31, a suspension arm 32 and a shock absorber 33. The connecting support rod 31 is pivoted to the frame 2 by a first rotating shaft 41, and the suspension arm 32 is A second rotating shaft 42 is pivoted on the connecting support rod 31. Wherein, the suspension arm 32 needs to be pivoted through the first rotation shaft 41 and the second rotation shaft 42, and the first rotation shaft 41 and the second rotation shaft 42 cannot be overlapped. Therefore, the first rotating shaft 41 can be used as a fulcrum for the suspension group 3 to expand and collapse; on the other hand, the second rotating shaft 42 can also be used as a fulcrum for the rear wheel 8 and suspension under the normal running state of the vehicle. The boom 32 performs up and down cushioning swing. In addition, one end of the shock absorber 33 is connected to the connecting support rod 31, and the other end of the shock absorber 33 is connected to the suspension arm 32, so that the suspension group 3 forms a triangular structure.

Furthermore, as shown in FIG. 3, the locomotive control structure 1 of the present invention includes a driving arm 5, a crank arm 6 and a buckling member 7.
