Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frames, in particular to a high-load-bearing and lightweight vehicle frame. Background Art

[0002] Electric balancing vehicles, also known as somatosensory vehicles, thinking vehicles, and camera vehicles, are mainly available in the market in two types: one-wheeled and two-wheeled. Two-wheeled electric balancing vehicles are a new type of transportation. Unlike electric bicycles and motorcycles, which have different front-to-back wheel arrangements, they use two wheels fixed side by side. Two-wheeled electric balancing vehicles are supported by two wheels, powered by batteries, driven by brushless motors, and controlled by single-chip microcomputers. The attitude sensor collects angular velocity and angle signals to coordinate and control the balance of the vehicle body. The vehicle can start, accelerate, decelerate, stop, and other actions by simply changing the center of gravity of the human body.

[0003] During the use of the electric balance scooter, the user stands directly on the frame, and the contact point between the frame and the user's feet is prone to wear and tear. However, the footrest part of the existing balance scooter is an integrated structure with the frame, and it is difficult to replace this part separately, resulting in inconvenience in use.

[0004] For this purpose, a high-load-bearing and lightweight frame is proposed. Utility Model Content

[0025] like Figures 1 to 5As shown, a high-load-bearing lightweight frame includes a mounting seat 1, support plates 2 are arranged on the left and right sides of the mounting seat 1, the side of the support plate 2 is rotatably connected with a mounting shaft 3 for mounting a wheel, a pedal 4 is movably inserted into the top surface of the support plate 2, and a locking component 5 for limiting the pedal 4 is arranged on the surface of the support plate 2, a sleeve 6 is movably inserted into the back side of the mounting seat 1, a handle 7 is movably inserted into the inner wall of the sleeve 6, a telescopic adjustment component 8 for controlling the extension length of the handle 7 from the inside of the sleeve 6 is arranged on the surface of the sleeve 6, and a positioning component 9 for limiting the sleeve 6 is arranged on the surface of the mounting seat 1. More specifically, when using the bicycle frame, the user will stand on the surface of the pedal 4. When the pedal 4 is worn, the locking assembly 5 is used to release the limit on the pedal 4, and the pedal 4 can be pulled to separate from the top of the support plate 2, thereby replacing the pedal 4. The telescopic adjustment assembly 8 can be used to control the handle 7 to slide along the inner wall of the sleeve 6, thereby changing the height of the handle 7. The positioning assembly 9 is used to release the limit on the sleeve 6, and the sleeve 6 can be pulled backward to separate from the surface of the mounting seat 1, thereby removing the sleeve 6.

[0026] The locking assembly 5 includes a mounting groove 501, and the mounting groove 501 is opened on the front side of the support plate 2. A spring 502 is fixedly connected to the bottom of the inner wall of the mounting groove 501, and a mounting block 503 is fixedly connected to the free end of the spring 502. A plug post 504 is fixedly connected to the top surface of the mounting block 503, and the plug post 504 is movably connected to the top wall of the mounting groove 501. A slot 506 is opened on the top surface of the support plate 2, and the inner wall of the slot 506 is movably connected to the pedal 4. A concave hole is opened on the bottom surface of the pedal 4, and the inner wall of the concave hole is movably connected to the top of the plug post 504. A paddle 505 is fixedly connected to the front side of the mounting block 503. It should be noted that by pulling the paddle 505 downward, the mounting block 503 is driven to slide along the inner wall of the mounting groove 501 and the spring 502 is compressed, thereby driving the plug post 504 to descend, so that the top end of the plug post 504 is separated from the inner wall of the recessed hole, thereby releasing the limit on the pedal 4, and pulling the pedal 4 to separate it from the inner wall of the slot 506, so that the pedal 4 can be disassembled.

[0027] The telescopic adjustment assembly 8 includes a screw rod 801, and the screw rod 801 is rotatably connected to the inner wall of the sleeve 6, and the screw rod 801 is threadedly connected to the handle 7. A worm wheel 802 is fixedly sleeved on the surface of the screw rod 801, and a worm 803 is rotatably connected to the surface of the sleeve 6, and the worm 803 is meshed with the worm wheel 802, and the front end of the worm 803 is fixedly connected with a first knob 804. More specifically, by rotating the first knob 804, the worm 803 is driven to rotate, thereby driving the worm wheel 802 meshed therewith to rotate, and the worm wheel 802 will drive the screw rod 801 to rotate, and under the action of the thread, the handle 7 will be pushed to slide along the inside of the sleeve 6, thereby changing the height of the handle 7, which is convenient for users of different heights to grasp.

[0028] The positioning assembly 9 includes an installation cavity 901, and the installation cavity 901 is opened on the back of the mounting base 1. The top surface of the mounting base 1 is rotatably connected to a threaded column 902, and the top of the threaded column 902 is fixedly connected to a second knob 903. The surface of the threaded column 902 is threadedly connected to a positioning rod 904. A slot 905 is opened on the surface of the sleeve 6, and the inner wall of the slot 905 is movably connected to the bottom end of the positioning rod 904.

[0029] The number of mounting grooves 501, springs 502, mounting blocks 503 and plug posts 504 on the surface of each support plate 2 is two groups, and the two groups of mounting grooves 501, springs 502, mounting blocks 503 and plug posts 504 are symmetrically arranged on the left and right sides of the bottom surface of the pedal 4. More specifically, by symmetrically arranging the two groups of mounting grooves 501, springs 502, mounting blocks 503 and plug posts 504, the bottom sides of the pedal 4 are fixed, so that the limit of the pedal 4 is more stable.

[0030] The top surface of the pedal 4 is fixedly connected with an anti-slip strip 10, and the anti-slip strip 10 is made of rubber. The surface of the handle 7 is fixedly connected with a sponge cover 11. The mounting seat 1, the support plate 2, the sleeve 6 and the handle 7 are all made of aluminum alloy. It should be noted that by setting the anti-slip strip 10 made of rubber material, the friction with the user's feet is increased, so that the user is not easy to slide when stepping on it. By setting the sponge cover 11, the user is more comfortable when grasping the handle 7 and is not easy to slip off. The aluminum alloy material has a lower density, so compared with traditional materials such as steel, the aluminum alloy frame is lighter, and the aluminum alloy has higher strength and rigidity, and can withstand larger loads and impact forces, so it has a high load-bearing and lightweight effect.

[0031] In summary: when using the frame, the user will stand on the surface of the pedal 4. When the pedal 4 is worn, the locking component 5 is used to release the limit on the pedal 4, and the pedal 4 can be pulled to separate from the top of the support plate 2, so that the pedal 4 can be replaced. The telescopic adjustment component 8 can be used to control the handle 7 to slide along the inner wall of the sleeve 6, so as to change the height of the handle 7. The positioning component 9 is used to release the limit on the sleeve 6, and the sleeve 6 is pulled backward to separate from the surface of the mounting seat 1, so that the sleeve 6 can be disassembled. During use, the effect of facilitating the rapid disassembly of the footrest is achieved, making it more convenient to replace the footrest after it is worn, and it can meet the needs of users of different heights. When carrying the balance car, the volume of the frame can be effectively reduced, making it more convenient to carry and transport.
