Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

The following is a more detailed description of the present invention:

the utility model provides an electric vehicle, this electric vehicle includes automobile body, locomotive, electric motor, battery and the control unit, and the locomotive includes the direction handle, and the handle is installed to the direction handle, and the automobile body has frame 1, preceding wheel, rear wheel to constitute, and frame 1 is connected with well and supports, and well support is equipped with controls its wobbling foot rest lever 9, as shown in fig. 3, 4.

The battery is used for supplying power, and electric motor is used for driving the rear wheel and rotates, and the control unit is used for controlling electric motor car work, including the work of control electric motor, indicator, headlight, loudspeaker, instrument etc. subassembly.

As shown in fig. 1 to 6, a middle support is disclosed, which comprises a support 2 for swingably connecting to an electric vehicle, a rotary connecting part 3 is provided at the upper end of the support 2, a support leg 4 is provided at the lower end of the support 2, a roller 5 is further included, the roller 5 is connected with a folding arm 6, the folding arm 6 is foldably connected with the support leg 4, the folding arm 6 has two states which can be switched with each other, the first state is a state in which the folding arm 6 is folded, the support leg 4 can be in contact with the ground to support the electric vehicle in a state in which the folding arm 6 is folded, the second state is a state in which the folding arm 6 is unfolded, the roller 5 is located at the lower side of the support leg 4, and the support 2 is in contact with the ground through the roller 5 to realize the rollable electric vehicle.

In some embodiments, as shown in fig. 5 and 6, the folding arm 6 is provided with a transverse portion 7, the roller 5 is connected to the lower side of the transverse portion 7, the upper side of the transverse portion 7 abuts against the supporting surface of the supporting leg 4 in the unfolded state of the folding arm 6, and the support 2 contacts with the ground through the roller 5 to realize the rollable support of the electric vehicle, which means that the roller 5, the transverse portion 7 and the supporting leg 4 form a force transmission path from bottom to top in sequence to realize the rollable support. After the design, on one hand, when the roller 5 is used for supporting, the supporting leg 4 can not be suspended, and on the other hand, when the roller 5 is used for supporting, the stress path mainly lies in the roller 5, the transverse part 7 and the supporting leg 4 from bottom to top, so that the other parts of the folding arm 6 are prevented from being used for stress supporting, the strength requirements of the other parts of the folding arm 6 can be obviously reduced, and the whole volume and the weight of the folding arm 6 can be further favorably reduced.

In some embodiments, the device further comprises an anti-disengagement structure, and in the second state, the anti-disengagement structure is used for maintaining the roller 5 to support the electric vehicle. After the design, the roller 5 is prevented from being separated from the ground due to the fact that the folding arm 6 rotates reversely when the electric vehicle is pushed. The anti-disengagement structure includes a hoop structure, a screw limiting structure, an elastic clamping structure and the like, and the elastic clamping structure is shown in fig. 2, 4 and 5.

In some embodiments, as shown in fig. 1, 2, 3 and 4, the folding arm 6 is a swing arm structure which can be swung relative to the support leg 4, and the lower end of the swing arm structure is provided with the roller 5. After the design, the folding arm 6 is simpler in structure and is beneficial to greatly reducing the structural complexity.

In some embodiments, as shown in fig. 1, 2, 3 and 4, the swing arm structure is disposed at the front side of the support foot 4, and the swing arm structure can swing in the front-back direction, and swing forward switches to the first state, and swing backward switches to the second state. This is convenient and the roller 5 is not easily detached from the leg 4 when pushed forward.

In some embodiments, as shown in fig. 1, 2, 3 and 4, the upper end of the swing arm structure is hinged with the lower part of the bracket 2, and the lower end of the swing arm structure can be mutually switched between two states around the hinge. So designed, the folding arm 6 is fully retractable, i.e. parallel to the support 2, in the first state.

Because the stress path mainly lies in the design of the roller 5, the transverse part 7 and the support leg 4 from bottom to top, the fixing jacket 10 can not bear the main supporting force, and the looseness of the fixing jacket 10 is avoided.

In some embodiments, as shown in fig. 1 to 6, the swing arm structure adopts a J-shaped structure, an upwardly open recess at a lower end of the J-shaped structure can be provided around the foot 4, and an elastic portion for elastically and tightly fitting the recess around the foot 4 is further included. After the design like this, simple structure is compact, small on the one hand, and on the other hand has realized the anti-disengaging structure simultaneously, but the elastic component is used for making concave part elasticity close-fitting wrap up stabilizer blade 4 and can be used to constitute the anti-disengaging structure promptly.

In some embodiments, as shown in fig. 1 to 6, the resilient portion is connected to the foot 4 and has a resilient bulge 8 rearward of the foot 4, the resilient bulge 8 being adapted to resiliently snap fit with the recess. Thus, the elastic part is arranged on the support leg 4, and the structure of the swing arm can be simplified.

In some embodiments, as shown in fig. 1 to 6, in order to further simplify the structure and reduce the weight, the elastic part is made of rustproof elastic steel sheets which wrap the supporting leg 4 from front to back, and the elastic steel sheets are rolled into a backward elastic bulge 8 at the back side of the supporting leg 4. At this time, in the second state, the roller 5, the lateral portion 7, the elastic steel sheet, and the leg 4 are stacked from the bottom to the top, and the lateral portion 7 and the leg 4 are still connected to each other by the elastic steel sheet, thereby transmitting the force.

In the first state, the stowed state may be maintained by providing a torsion spring at the hinge, or other arrangements may be used, such as a removable clip that embraces the folding arm 6 to maintain the stowed state.

Therefore, according to the technical scheme, the electric vehicle is simple in structure, light in weight, convenient to use and high in practicability, and in addition, the existing electric vehicle can be conveniently transformed.

The above description is only an illustrative embodiment of the present invention, and therefore all equivalent changes or modifications made by the structure, features and principles of the present invention are included in the protection scope of the present invention.
