[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] See Figure 1 、 Figure 2 and Figure 3 The utility model discloses a unicycle balancing vehicle frame.

[0036] A unicycle frame includes a housing 1 2 and a housing 2 3, respectively disposed on either side of a wheel 1. A fixing member is connected between the housing 1 2 and the housing 2 3. The fixing member secures the housing 1 2 and the housing 2 3, maintains the relative positions of the housing 1 2 and the housing 2 3, and integrally connects the housing 1 2 and the housing 2 3, facilitating the fixed installation of the housing 1 2 and the housing 2 3 to the wheel 1, ensuring the relative positions of the housing 1 2 and the housing 2 3 to the wheel 1, and ensuring that the housing 1 2 and the housing 2 3 are located on either side of the wheel 1.

[0037] The fixed connection members include a first fixing member 4 and a second fixing member 5. The first fixing member 4 is fixedly connected to both the first and second housings 2 and 3, and the second fixing member 5 is fixedly connected to both the first and second housings 2 and 3. The first fixing member 4 and the second fixing member 5 can each independently fix the first and second housings 2 and 3. The first fixing member 4 and the second fixing member 5 are respectively fixedly connected to the first and second housings 2 and 3. Preferably, the first fixing member 4 and the second fixing member 5 are respectively removably fixed to the first and second housings 2 and 3, typically by connecting screws, bolts, etc.

[0038] The first fixing member 4 and the second fixing member 5 are arranged on the self-balancing vehicle at front and rear positions along the direction of travel of the self-balancing vehicle. When the self-balancing vehicle is in an upright position, the first fixing member 4 and the second fixing member 5 are respectively arranged on either side of the vertical centerline of the self-balancing vehicle. The first fixing member 4 and the second fixing member 5 maintain the balance and stability of the self-balancing vehicle while maintaining the fixing of the housing 1 2 and the housing 2 3. This allows the first fixing member 4 and the second fixing member 5 to serve as handles for lifting the self-balancing vehicle. When the first fixing member 4 and the second fixing member 5 serve as handles for lifting the self-balancing vehicle, the first fixing member 4 and the second fixing member 5 are ensured to be evenly loaded, ensuring that the self-balancing vehicle can be lifted with minimal lifting force, thus saving effort when lifting the self-balancing vehicle.

[0039] The first fixing member 4 includes a first lifting rod 41, and the second fixing member 5 includes a second lifting rod 51. The first lifting rod 41 and the second lifting rod 51 are both arranged across the circumferential outer side of the wheel 1. The first lifting rod 41 and the second lifting rod 51 are used for people to grab during transportation. The position setting of the first lifting rod 41 and the second lifting rod 51 allows the first lifting rod 41 and the second lifting rod 51 to be used for people to grab during transportation, specifically when transporting the unicycle. When lifting the unicycle, the operator can more conveniently hold the first lifting rod 41 and the second lifting rod 51, which is convenient for lifting the unicycle and the lifting operation is convenient.

[0040] Based on the above solution, the fixed connection part between shell 1 2 and shell 2 3 is also used as a handle for lifting the balance car, realizing the multifunctionality of the fixed connection part. There is no need to set up a separate handle specifically for lifting the balance car, simplifying the frame structure, reducing costs, reducing the volume, and realizing a lightweight frame.

[0041] In this technical solution, the first lifting rod 41 and the second lifting rod 51 are both located on the upper part of the horizontal center line of the balance vehicle in the upright state, so that the setting positions of the first lifting rod 41 and the second lifting rod 51 are reasonable and will not affect the movement of the wheel 1. In addition, it is convenient to apply force when lifting the balance vehicle. According to the principle of force, the first lifting rod 41 and the second lifting rod 51 are both located on the upper part of the horizontal center line of the balance vehicle in the upright state, and a smaller force can be applied to lift the balance vehicle, which is convenient for saving effort when carrying the balance vehicle.

[0042] In the present technical solution, based on the fact that the first lifting rod 41 and the second lifting rod 51 are both located above the horizontal center line of the upright balance vehicle, generally, the angle between the virtual line connecting the first lifting rod 41 and the center of the wheel 1 and the vertical center line of the upright balance vehicle is 20° to 80°; the angle between the virtual line connecting the second lifting rod 51 and the center of the wheel 1 and the vertical center line of the upright balance vehicle is 20° to 80°, ensuring that the first lifting rod 41 and the second lifting rod 51 are respectively arranged on both sides of the vertical center line of the balance vehicle, and are also located above the horizontal center line, so that when transporting the balance vehicle, the transport operation is convenient and labor-saving.

[0043] Preferably, the angle between the virtual line connecting the first lifting rod 41 and the center of the wheel 1 and the vertical center line of the upright balance vehicle is 45° to 65°, and the angle between the virtual line connecting the second lifting rod 51 and the center of the wheel 1 and the vertical center line of the upright balance vehicle is 45° to 65°.

[0044] In this technical solution, the first lifting rod 41 and the second lifting rod 51 are adapted to the horizontal center line distance of the upright balance car, that is, in the vertical direction, the heights of the first lifting rod 41 and the second lifting rod 51 are basically the same. In this way, when the balance car is lifted by both hands, the heights of the two hands are consistent, which is convenient for the arms to apply force, and also improves the comfort of carrying and achieves labor saving.

[0045] See Figure 4 , is a side view of a unicycle, to simplify the structure, Figure 4 The structures such as the pedals to be installed on the side of the frame are not shown. Figure 4 In the figure, the scooter is in an upright position. The dotted line L1 is the horizontal centerline of the scooter, and the dot-dash line L2, perpendicular to the dotted line L1, is the vertical centerline of the scooter. Angle a is the angle between the virtual line connecting the first lifting lever 41 and the center of wheel 1 and the vertical centerline of the scooter in the upright position. Angle b is the angle between the virtual line connecting the second lifting lever 51 and the center of wheel 1 and the vertical centerline of the scooter in the upright position.

[0046] In this technical solution, the first fixing member 4 also includes a connecting seat 1 42 and a connecting seat 2 43 respectively fixed to the shell 1 2 and the shell 2 3. The two ends of the first lifting rod 41 are respectively fixed to the connecting seat 1 42 and the connecting seat 2 43. Preferably, the two ends of the first lifting rod 41 are respectively detachably fixed to the connecting seat 1 42 and the connecting seat 2 43, such as by using connecting screws or connecting bolts. The connecting seat 1 42 and the connecting seat 2 43 realize the fixed connection between the two ends of the first lifting rod 41 and the shell 1 2 and the shell 2 3, facilitate the installation and fixed connection of the first lifting rod 41 and the shell 1 2 and the shell 2 3, improve the strength of the connection between the first lifting rod 41 and the shell 1 2 and the shell 2 3, and avoid damage to the shell 1 2 and the shell 2 3 when the balance vehicle is lifted by the first lifting rod 41.

[0047] The second fixing member 5 also includes a third connecting seat 52 and a fourth connecting seat 53, which are respectively fixed to the housing 1 2 and the housing 2 3. The ends of the second lifting rod 51 are respectively fixed to the third connecting seat 52 and the fourth connecting seat 53. The third connecting seat 52 and the fourth connecting seat 53 secure the ends of the second lifting rod 51 to the housing 1 2 and the housing 2 3, facilitating the installation and securement of the second lifting rod 51 to the housing 1 2 and the housing 2 3, improving the strength of the connection between the second lifting rod 51 and the housing 1 2 and the housing 2 3, and preventing damage to the housing 1 2 and the housing 2 3 when the balancing vehicle is lifted by the second lifting rod 51.

[0048] In this technical solution, a third fixing rod 45 and a headlight 46 are fixedly connected between the first and second connectors 42, 43. The headlight 46 faces the road surface in front of the self-balancing vehicle. The third fixing rod 45 secures and connects the first and second connectors 42, 43, ensuring a secure connection between them and increasing the strength of the first fixing member 4. The headlight 46 is provided to illuminate the road surface during driving. Placing the headlight 46 on the first fixing member 4 facilitates installation, eliminating the need for a separate mounting bracket for the headlight 46, simplifying the structure and reducing costs.

[0049] Both the first and second connectors 42, 43 partially protrude from the first and second housings 2, 3, providing collision protection. Typically, the first and second housings 2, 3, are made of plastic and easily damaged in a collision. In this embodiment, the first lifting rod 41 is secured to the first and second connectors 42, 43 at both ends, allowing the first and second connectors 42, 43 to absorb and protect the frame.

[0050] In this technical solution, the ends of the third and fourth connectors 52 and 53 extend toward the rear and lower sides of the wheel 1 and extend beyond the first and second housings 2 and 3, allowing the second fixing member 5 to also serve as a support for the scooter. When parking or storing the scooter, the end of the second fixing member 5 rests against the ground or a table, securing the scooter and preventing it from tipping over or moving forward. Anti-skid portions 54 are also fixed to the ends of the third and fourth connectors 52 and 53, preventing the second fixing member 5 from slipping on the ground or table, ensuring the scooter's stability.

[0051] In the present technical solution, the unicycle frame also includes a mudguard. When the unicycle is upright, the mudguard is located above the wheel 1, and the mudguard is at least located below the first lifting rod 41 and the second lifting rod 51. The mudguard prevents dust or muddy water raised during driving from falling onto the first lifting rod 41 and the second lifting rod 51, ensuring that the first lifting rod 41 and the second lifting rod 51 are clean and hygienic, making it convenient to keep the unicycle clean when transporting the unicycle through the first lifting rod 41 and the second lifting rod 51.

[0052] In this technical solution, the unicycle frame also includes a third lifting rod 6, which is connected to the housing 1 and the housing 2 3. When the unicycle is in an upright state, the third lifting rod 6 is located directly above the wheel 1. When lifting the unicycle over a short distance, it can be lifted separately by the third handle, which is convenient to operate.

[0053] In the present technical solution, a unicycle is also proposed, which comprises a wheel 1 and the aforementioned unicycle frame, wherein the unicycle frame is mounted on the wheel 1. The unicycle frame is used in the unicycle, making the unicycle easy to carry.
