DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In order to make the above purpose, features and advantages of the invention more obvious and easy to understand, the specific implementation mode of the invention is described in detail below in combination with the attached drawings. Many specific details are described in the following description to facilitate a full understanding of the invention. However, the invention can be implemented in many other ways that are different from those described herein. The technicians in the field can make similar improvements without violating the connotation of the invention. Therefore, the invention is not restricted by the specific embodiments disclosed below.

A preferred implementation mode of the invention is described below in combination with the attached drawings.

The embodiment of the application provides a kind of vehicle frame, which can be a Karting frame modified by a balance vehicle. The modified Karting takes the balance vehicle as the driving component. The following embodiment is adopted for the connection structure between the frame and the balance vehicle.

The connecting structure of balance vehicle frame in the embodiment of the application is shown in Figures 1 to 4., including at least one clamping mechanism 100 for clamping driving components. The clamping mechanism 100 includes: a first clamping component 110 and a second clamping component 120, the first clamping component 110 and the second clamping component 120 can be arranged through relative motion. The first clamping component 110 includes a first connecting part 111 and a first clamping plate 112. The second clamping component 120 includes a second connecting part 121 and a second clamping plate 122. The first clamping plate 112 and the second clamping plate 122 are arranged opposite to each other. The self-locking structure includes a limit block 170 and a length adjusting mechanism 180. The first connecting part 111 and the second connecting part 121 are both provided with the limit blocks 170. The length adjusting mechanism 180 is installed between the two limit blocks 170.

It should be noted that the setting through relative motion for the first clamping component and the second clamping component 120 means that the distance between the first clamping plate 112 and the second clamping plate 122 can be increased or reduced, which can adapt to the widths of different driving components by adjusting of the relative positions of the first clamping plate 112 and the second clamping plate 122.

It should be noted that the two limit blocks 170 arc integrally formed or fixedly connected with the first connecting part 111 and the second connecting part 121 respectively. When adjusting the spacing between the two limit blocks 170, the effect of adjusting the spacing between the first clamping plate 112 and the second clamping plate 122 can be realized.

The connecting structure of balance vehicle frame in the above scheme is usually installed between the seat and the driving component of the balance vehicle. The driving component is usually a balance vehicle. By moving the relative position of the first clamping plate 112 and the second clamping plate 122, the driving component is fastened by using the structures of the first clamping plate 112 and the second clamping plate 122 themselves, which is no need to use strap for fixing to avoid the potential safety hazards caused by the easy fracture of plastic strap. At the same time, the installation and disassembly steps are reduced to make the installation more convenient.

Please continue to refer to Figures 1, 3 and 4. Further, the number of the clamping mechanisms 100 are two, and a connecting rod 200 is detachably connected between the two clamping mechanisms 100. The two clamping mechanisms 100 correspond to the two pedals of the balance vehicle respectively, and the connecting rod 200 between the clamping mechanisms 100 is used to connect the frame.

Please continue to refer to Figures 1 to 4. Further, the first clamping plate 112 comprises a first connecting plate 130 and a first clamping plate 140, the first connecting plate 130 is connected with the first connecting part 111. The second clamping plate 122 comprises a second connecting plate and a second clamping plate, the second connecting plate is connected with the second connecting part 121. The included angle between the first connecting plate 130 and the first clamping plate 140 is an obtuse angle; the included angle between the second connecting plate and the second clamping plate is an obtuse angle. The obtuse angle structure between each connecting plate and the clamping plate can not only prevent the driving components from sliding under the fastening state, but also facilitate the placement of the driving components, which is suitable for different thicknesses of different types of driving components.

Specifically, referring to Fig. 3, the first connecting plate 130 and the second connecting plate extend obliquely in the direction away from each other. The first clamping plate 140 and the second connecting plate extend obliquely in the direction close to each other. In the combined state of the first clamping component 110 and the second clamping component 120, the side presents a structure of the "C-shaped" grab. Through this structure, the clamping mechanism 100 can hook the driving component to prevent it from sliding. More specifically, in the relative sliding direction of the first clamping plate 112 and the second clamping plate 122 (left and right directions in Fig. 3), the first connecting plate 130 and the second connecting plate tilt outward, then a large clamping space is formed between them. At the same time, the first clamping plate 140 and the second connecting plate tilt inward and are close to each other, and an entrance smaller than the clamping space is formed between the ends of the first connecting plate 130 and the second connecting plate, which makes the first clamping plate 140 and the second connecting plate hook the driving component to prevent it from sliding.

Please continue to refer to Figures 1 to 4. Further, an elastic gaskets 150 are set respectively for the first clamping plate 112 and the second clamping plate 122 on the sides in contact with the driving component, which makes the first clamping plate 112 and the second clamping plate 122 fit with the driving component. In the clamped state, the elastic gaskets 150 are subjected to pressure on both sides, and the side wall in contact with the driving component can fully fit with that of the driving component, the shell curvature of the balance vehicle is formed automatically, which makes the first clamping plate 112 and the second clamping plate 122 more fit with the driving component.

The elastic gaskets 150 are arranged on the inner side of the first clamping plate 112 and the second clamping plate 122. In the embodiment, the inner sides refer to the sides facing the clamping space by the first clamping plate 112 and the second clamping plate 122 respectively. Accordingly, the outer sides of the first clamping plate 112 and the second clamping plate 122 refer to the sides facing away from the clamping space.

In the embodiment, the foam pad can be selected for the elastic gaskets 150. Through the structural gap inside the foam pad, the foam pad will automatically form the shell curvature of the balance vehicle when the first clamping plate 112 and the second clamping plate 122 are connected and clamped with the driving component, which makes the connecting structure more fit with the driving component.

Please continue to refer to Figures 2, 3. Further, a slide rail 160 is arranged for one of the first connecting part 111 and the second connecting part 121, and the other one is slidably connected with the slide rail 160. For example, the slide rail 160 is arranged for the second connecting part 121, the first connecting part 111 can slide on the slide rail 160, or the slide rail 160 is arranged for the first connecting part 111, the second connecting part 121 can slide on the slide rail 160.

In the embodiment, the slide rail 160 is arranged for the second connecting part 121, and the spacing between the first clamping plate 112 and the second clamping plate 122 is adjusted by changing the position of the first connecting part 111.

Please continue to refer to Figures 1 to 3. Further, the sliding rail 160 and the first connecting portion 111 or the second connecting portion 121 are integral structures, and the sliding rail 160 is formed by folding the edge of the first connecting portion 111 or the second connecting portion 121. In the embodiment, when the slide rail 160 is arranged for the first connecting part 111, the slide rail 160 is formed by folding the edge of the first connecting part 111 upward and outward, and when the slide rail 160 is arranged for the second connecting part 121, the slide rail 160 is formed by folding the edge of the second connecting part 121 upward and outward.

It should be noted that the integral structure mentioned here is not limited to one -piece molding, which can also be formed by fixed connection mode such as welding.

Please continue to refer to Figures 2, 3. Further, the length adjusting mechanism 180 comprises a quick release screw 181 and a handle 182, the two limit blocks 170 are connected through the quick release screw 181, both of the limit blocks 170 are provided with threaded holes suitable for the quick release screw 181. The quick release screw 181 is inserted into the threaded holes of the two limit blocks 170, and the length of the quick release screw 181 is adjusted by rotating the handle 182 to adjust the spacing between the two limit blocks 170, which achieves the effect of adjusting the spacing between the first clamping plate 112 and the second clamping plate 122.

Please continue to refer to Fig. 2. Further, the handle 182 is hinged with the quick release screw 181 through a rotating shaft 183, and the rotating shaft 183 is arranged perpendicular to the quick release screw 181. The handle 182 can rotate around the rotating shaft 183. After the spacing between the first clamping plate 112 and the second clamping plate 122 is adjusted in place, rotate the handle 182 close to the first clamping plate 112 or the second clamping plate 122 to prevent foreign matters from being scratched during the use of the balance vehicle frame, which avoids potential safety hazards.

In the embodiment, as shown in Fig. 3, the handle 182 is an eccentric handle, one end of it is a hinged end 1821 with circular contour, which is hinged with the quick release screw 181. The other end is the holding end 1822. When it is necessary to adjust the spacing between the first clamping plate 112 and the second clamping plate 122, hold the holding end 1822 to make the eccentric handle drive the quick release screw 181 to rotate, and the spacing between the two limit blocks 170 is increased or decreased through the thread matching of the limit block 170 and the quick release screw 181, which adjusts the spacing between the first clamping plate 112 and the second clamping plate 122. When the spacing between the first clamping plate 112 and the second clamping plate 122 is adjusted in place, rotate the eccentric handle around the rotating shaft 183 to make the holding end 1822 close to the first clamping plate 112 or the second clamping plate 122, and the limit block 170 is pressed by the hinged end 1821, which locks the limit block 170.

It should be noted that the hinged end of the eccentric handle is eccentrically set.

Specifically, when the holding end 1822 is close to the first clamping plate 112 or the second clamping plate 122, the distance between the rotating shaft 183 and the outer contour of the hinged end 1821 is greater than the distance between the rotating shaft 183 and the outer contour of the hinged end 1821 when the holding end 1822 is horizontal with the quick release screw 181. Further, when the holding end 1822 is close to the first clamping plate 112 or the second clamping plate 122.

The hinged end 1821 is connected to the limit block 170, and when the holding end 1822 is horizontal with the quick release screw 181, the hinged end fits with the limit block 170. Thus, when the holding end 1822 is pressed close to the first clamping plate 112 or the second clamping plate 122, the limit block 170 is presses by the hinged end 1821, which locks the limit block 170.

Please continue to refer to Figures 1 to 3. Further, the outer sides of the first clamping plate 112 and the second clamping plate 122 are set with reinforcing bars to prevent the first clamping plate 112 and the second clamping plate 122 from being subjected to excessive force or breaking under long-term stress. Specifically, the reinforcing bars 190 may be made of the same material as the first clamping plate 112 and the second clamping plate 122 and be integral with the first clamping plate 112 or the second clamping plate 122.

Specifically, when it is necessary to install the vehicle frame on the driving component, only use the handle 182 to remove the quick release screw 181 to make the first clamping component 110 and the second clamping component 120 move relatively along the slide rail 160. When the distance between the first clamping plate 112 and the second clamping plate 122 is larger than the driving component during moving, place the driving component on the position between the first clamping plate 112 and the second clamping plate 122. Then move the first clamping component 110 and the second clamping component 120 back along the slide rail 160. After connecting the two limit blocks 170 with quick release screw 181, the quick release screw 181 is tightened with handle 182 to complete the installation. After installation, under the action of the elastic gaskets 150, the first clamping plate 112 and the second clamping plate 122 can fit with the outer surface of the driving component to achieve the fastening effect. By using of the installation mode, the first clamping component 110 and the second clamping component 120 are fastened by using the built-in handle 182 to drive the quick-release screw 181 to rotate without using other tools other than the connecting structure, which avoids the inconvenience caused by the lack of spare tools when installing and disassembling, and can be installed and disassembled anytime and anywhere, thus the restrictions of external conditions are gotten rid of The technical features of the above embodiments can be combined arbitrarily.
