Description

Linkage control mechanism of folding vehicle

The invention relates to a linkage control mechanism for folding vehicles, in particular to a linkage control mechanism suitable for folding vehicles with adjustable relative wheelbase.

In the conventional technology, the frame structure of the vehicle is generally unable to change its shape, so it is not easy to accommodate a large volume, and when entering and exiting a narrow place, such as: the rear compartment of the vehicle, the public transportation system, the elevator, etc., Limited by the size of the vehicle itself, it becomes difficult to get in and out, causing problems in use. Secondly, the rear shock absorber of the traditional vehicle is fixed on the rear frame and the rear suspension arm, so that the rear shock absorber and the rear suspension arm cannot be easily adjusted and collapsed, and the wheelbase cannot be adjusted elastically, resulting in inconvenience in transportation. Sex.

Because of this, the inventor, in the spirit of active invention, is anxious to think of a linkage control mechanism with folding vehicle that can solve the above-mentioned problems. After several studies and experiments, the present invention has been completed.

The main object of the present invention is to provide a linkage control mechanism for a folding vehicle. The linkage control mechanism of the present invention is used to adjust and fix the relative wheelbase of the rear suspension arm group, and drive the upper first buckling mechanism through the driving member Close or open, and then drive the lower second locking mechanism through the link to buckle or open to provide the position of the rear suspension arm group folding or opening, so that the folding group is in an expanded position or a closed position after folding the vehicle . Among them, when the wheelbase is shortened, the whole vehicle can be easily moved and placed in a limited space to be transported to each floor, improving the convenience of movement.

In order to achieve the above object, the linkage control mechanism of the folding vehicle of the present invention is provided on a car body, which has a first fixed point and a second fixed point, which can be used for the linkage control mechanism to engage or open. It includes a supporting assembly, a linkage mechanism, a first buckling mechanism and a second buckling mechanism. The supporting assembly includes a first supporting cantilever and a second supporting cantilever, which are fixed on the vehicle body and used for carrying and supporting the following components. The linking mechanism includes an upper pivoting portion, a lower pivoting portion, a driving member and a linking member, the upper pivoting portion and the lower pivoting portion are respectively pivotally mounted on a fixed pin fixed between the supporting components, and the upper pivoting portion extends A driving crank arm with a long slot hole is provided, and the driving member is penetrated in the first support cantilever, including a crank and a link pin, the link pin is slidably set in the long slot hole to drive, and the two ends of the link member are fixed respectively At the upper pivoting portion and the lower pivoting portion, the force applied by the driving member is transmitted through the linking member, so that the second locking mechanism produces a linking effect.

The first buckling mechanism is pivotally arranged on the upper pivoting portion with a first buckling pin for buckling or opening the first fixing point; the second buckling mechanism is pivotally arranged on the lower with a second buckling pin The pivoting part is used to buckle or open the second fixed point. With the above design, regardless of whether the suspension group is in the unfolded or retracted position after folding the vehicle, the linkage control mechanism can achieve the function of buckling and opening with the first fixed point or the second fixed point, which is convenient for the rider. Wheelbase adjustment.

When the suspension group of the folding vehicle is in the unfolded position, the first fixing point can be locked by the first locking mechanism; when the suspension group of the folding vehicle is in the folded position, the second fixing point can be locked by the second locking mechanism . In this way, according to the different positions of the rear suspension group, different fixing components can be selectively engaged to respectively fix the deployed position and the retracted position.

The crank of the above-mentioned driving member can be further connected with a handle, which is convenient for the user to control the state of the first and second snapping mechanisms. In this way, in addition to facilitating the user to apply force and rotation, it is easier to understand the current switching state of the first buckling mechanism and the second buckling mechanism.

The above-mentioned first buckling mechanism can be further connected to a first spring to provide a restoring force for buckling or opening. In this way, after the first buckling mechanism is opened briefly, the first fixing point is tightly buckled through the spring force, and the rear suspension group is indeed kept in an unfolded position.

The above-mentioned second buckling mechanism can be further connected to a second spring to provide a restoring force for buckling or opening. Thereby, the second buckling mechanism can be briefly opened and then buckle the second fixing point tightly through the spring force, and indeed keep the rear suspension group in a closed position.

The above-mentioned linking member may be a connecting rod. Therefore, through the installation of an elongated rod, the fastening mechanism at different parts can be driven together to complete the fixed operation of the deployed position and the retracted position.

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

Please refer to FIGS. 1 to 3, which are respectively an exploded view of the linkage control mechanism of a folding vehicle of the present invention, a side view of the suspension group in the folded position after folding the vehicle, and a partially enlarged view of FIG. The figure discloses a linkage control mechanism 1 of a folding vehicle, which is arranged on a car body 10, and the car body 10 has a first fixed point 101 and a second fixed point 102, which can be used for the linkage control mechanism 1 to buckle or The action of opening. In this way, when the suspension group and the rear wheels are adjusted to form an unfolded position and a retracted position after folding the vehicle, the present invention can be buckled and fixed, so that the vehicle can be stably maintained in the above position state. Adjust the wheelbase elastically.

The linkage control mechanism 1 of the folding vehicle of the present invention includes a support assembly 2, a linkage mechanism 3, a first buckling mechanism 4 and a second buckling mechanism 5. In this embodiment, the support assembly 2 is composed of a first support cantilever 21 and a second support cantilever 22, and is fixed on the vehicle body 10 for carrying and supporting other internal components.

The linking mechanism 3 includes an upper pivot portion 31, a lower pivot portion 32, a driving member 33, and a linking member 34.
