[0005] According to a first aspect of this application, a two-wheeled self-balancing vehicle is provided, including a frame assembly and two wheels. The frame assembly includes a frame body and a counterweight. The two wheels are disposed opposite to each other on both sides of the frame body in a first direction.

[0012] Based on the above technical features, it is not only convenient to fix the drive unit into the frame body and ensure the stability of the drive unit, but also to further ensure that the counterweight compartment is located below the axis of the wheel in the direction of gravity, thereby improving the stability and balance of the two-wheeled balance vehicle.

[0013] Preferably, the drive unit includes two rotary drive members, which are capable of being inserted into the drive compartment from both ends in the first direction.

[0014] The two rotary drive components are respectively connected to the two wheels.

[0015] Based on the above technical features, independent control of the two wheels can be achieved, thereby realizing differential control of the two wheels, which facilitates the turning action of the two-wheeled self-balancing vehicle and reduces the probability of the two-wheeled self-balancing vehicle tipping over during the turning process.

[0016] Preferably, the drive mounting part is further provided with a wiring operation part, which is located in the middle of the drive mounting part in the first direction, and the wiring operation part penetrates the side wall of the drive compartment and is connected to the drive compartment.

[0019] The drive unit is located at the center of the counterweight unit in the second direction.

[0020] Based on the above technical features, on the one hand, it is convenient for the drive mounting part to adapt to the size of the drive component; on the other hand, by setting the drive mounting part in the middle of the counterweight mounting part in the second direction, the swing stability of the frame body in the second direction can be effectively improved.

The main control connector is used to connect to the main control board. The wiring connector is used to connect to the drive unit and the battery, respectively. The main control connector and the wiring connector are located at opposite ends of the board body.

[0030] Based on the above technical features, the wiring connector is located at one end of the board body 51, which facilitates the connection between the expansion board and the battery and drive components. On the other hand, the main control connector and the wiring connector are respectively located at opposite ends of the board body, which not only prevents the main control board from interfering with the connection between the expansion board and the battery and drive components, but also effectively ensures the uniformity of force on the board body, thereby improving the stability of the two-wheeled balance vehicle.

[0031] According to a second aspect of this application, a toy is provided, comprising the two-wheeled self-balancing vehicle described in any of the above technical solutions, and thus possesses all the beneficial technical effects of the two-wheeled self-balancing vehicle, which will not be repeated here.

[0032] Compared with the prior art, the beneficial effects of this application are as follows:

[0033] The two-wheeled self-balancing scooter provided in this application has a counterweight typically located below the wheel axle (i.e., near the bottom of the frame). This effectively lowers the center of gravity, allowing it to be closer to the ground. If the scooter tilts, gravity allows it to quickly return to its upright position, significantly improving stability and reducing the likelihood of tipping over. This avoids the need for PID balancing algorithms combined with electronic gyroscopes for stable control, effectively reducing material costs, simplifying control programming, and lowering the barrier to entry for two-wheeled self-balancing scooters.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] The following reference Figures 1 to 6This application describes a two-wheeled self-balancing scooter and toy according to some embodiments thereof.

[0050] See Figures 1 to 6 As shown, an embodiment of the first aspect of this application provides a two-wheeled self-balancing vehicle, which includes a frame assembly and two wheels 4. The frame assembly includes a frame body and a counterweight 2. The two wheels 4 are disposed opposite to each other on both sides of the frame body in a first direction F1. The counterweight 2 is fixed to the frame body. The wheels 4 have an axle. When the two-wheeled self-balancing vehicle is in use, the counterweight 2 is located below the gravity direction G on the axis of the wheels 4. The first direction F1 is perpendicular to the gravity direction G.

[0051] According to the technical features described above, in a two-wheeled self-balancing scooter, the counterweight 2 is typically located below the axle of the wheel 4 (i.e., near the bottom of the frame). This effectively lowers the center of gravity of the scooter, allowing it to be closer to the ground. If the scooter tilts, it can quickly return to its upright position under gravity, greatly improving its stability and reducing the likelihood of tipping over. This avoids the need for PID balancing algorithms combined with electronic gyroscopes to achieve stable control, effectively reducing material costs, simplifying control programming, and lowering the barrier to entry for scooters.

[0052] like Figures 1 to 6 As shown in the figure, F1 can be an example of the first direction F1 mentioned above, and G can be the gravitational direction G mentioned above. For ease of description, the direction perpendicular to the plane determined by both the first direction F1 and the gravitational direction G is defined as the second direction F2, and F2 shown in the figure can be an example of the second direction F2 mentioned above.

[0053] Preferably, such as Figure 3 As shown, the frame body may include a counterweight mounting part 11, the counterweight mounting part 11 is provided with a counterweight compartment 110, the counterweight compartment 110 is located below the axis of the wheel 4 in the direction of gravity G, and the counterweight part 2 is fixedly installed in the counterweight compartment 110 so that the frame body can easily accommodate the counterweight part 2.

[0054] Preferably, such as Figure 3 As shown, the counterweight mounting part 11 can be a rectangular tube extending along the first direction F1, so that the two bottom edges on both sides of the counterweight mounting part 11 in the second direction F2 are right-angled edges.

[0055] like Figure 5 As shown, on a plane perpendicular to the axis of wheel 4, the distance from the axis of wheel 4 to the right-angled edge is L, the distance between the axis of wheel 4 and the bottom of the counterweight mounting part 11 is H, and the radius of wheel 4 is R.

[0056] Optionally, H < R < L, to be suitable for low-speed two-wheeled self-balancing vehicles. In this way, when the frame body swings about the wheel axis, the right-angled edge can be brought into contact with the ground to quickly stop the swing.

[0057] Optionally, R≥L is suitable for high-speed two-wheeled self-balancing vehicles. In this way, when the two-wheeled self-balancing vehicle stops suddenly at high speed, R≥L can effectively prevent the right-angle edge from getting stuck on the ground. This allows the kinetic energy accumulated in the high-speed sudden stop of the two-wheeled self-balancing vehicle to be released by the swing of the frame body. This effectively prevents the inertia of the two-wheeled self-balancing vehicle and the reaction force of the collision between the right-angle edge and the ground from conflicting with each other, which would cause the two-wheeled self-balancing vehicle to tip over.

[0058] Preferably, such as Figure 6 As shown, the aforementioned counterweight 2 can be a metal counterweight block. Figure 6 An example of the aforementioned counterweight 2 including a single metal counterweight is shown; however, it is not limited to this. As long as the uniformity of the distribution of the metal counterweights on the frame body is ensured, the aforementioned counterweight 2 may also include multiple metal counterweights.

[0059] Preferably, such as Figure 5 and Figure 6 As shown, the counterweight 2 can be bonded and fixed to the inner wall of the counterweight chamber 110 via the adhesive layer 14 to ensure the stability of the counterweight 2.

[0060] Optionally, the adhesive layer 14 can be foam adhesive, which not only facilitates assembly but also reduces the likelihood of abnormal noises from the two-wheeled self-balancing scooter.

[0061] The aforementioned two-wheeled self-balancing scooter may further include a battery 3 to provide electrical power to the scooter. Preferably, as shown in the image... Figures 4 to 6 As shown, the battery 3 is fixedly installed inside the counterweight compartment 110 so that the weight of the battery 3 can be used to further lower the center of gravity of the two-wheeled self-balancing vehicle, thereby improving the stability and balance of the two-wheeled self-balancing vehicle.

[0062] Preferably, such as Figure 4 As shown, the aforementioned counterweight placement part 11 is also provided with a first wire hole 111, which penetrates the wall of the counterweight compartment 110 and is connected to the counterweight compartment 110 so as to facilitate the external wiring of the battery 3.

[0063] Preferably, such as Figure 5 and Figure 6 As shown, the adhesive layer 14 can also be provided between the battery 3 and the counterweight 2 to fix the battery 3 by bonding.

[0064] Preferably, such as Figure 3 , Figure 5 and Figure 6 As shown, the frame body may further include a drive unit 12, which has a drive compartment 120. The drive unit 12 is located on top of the counterweight unit 11, and the drive compartment 120 extends through the drive unit 12 along a first direction F1. The two-wheeled self-balancing vehicle may further include a drive unit, which is located inside the drive compartment 120 and is connected to two wheels 4 for transmission, thereby driving the two wheels 4.

[0065] Preferably, such as Figure 3 , Figure 5 and Figure 6 As shown, in the second direction F2, the size of the counterweight mounting part 11 is larger than the size of the drive mounting part 12. The drive mounting part 12 is located in the middle of the counterweight mounting part 11 in the second direction F2. In this way, on the one hand, it is convenient for the drive mounting part 12 to adapt to the size of the drive member 6. On the other hand, by setting the drive mounting part 12 in the middle of the counterweight mounting part 11 in the second direction F2, the swing stability of the frame body in the second direction F2 can be effectively improved.

[0066] Preferably, the drive unit can be inserted into the drive compartment 120 with an interference fit, so that the drive unit can be fixed by the inner wall of the drive compartment 120, thereby effectively reducing the number of parts for fixing the drive unit, thereby reducing material costs and saving space occupied by the two-wheeled balance vehicle.

[0067] Preferably, such as Figure 3 As shown, the inner wall of the drive compartment 120 is provided with a limiting protrusion 122, so that the position of the drive component 6 in the first direction F1 is limited by the engagement between the limiting protrusion 122 and the drive component 6.

[0068] Preferably, such as Figure 6 As shown, the aforementioned drive unit may include two rotary drive components 6, which can be inserted into the drive housing 120 from both ends in the first direction F1. The two rotary drive components 6 are respectively connected to the two wheels 4 to achieve independent control of the two wheels 4, thereby achieving differential control of the two wheels 4, which facilitates the turning action of the two-wheeled self-balancing vehicle and reduces the probability of the two-wheeled self-balancing vehicle tipping over during the turning process.

[0069] However, it is not limited to this. The aforementioned drive unit may also include a rotary drive member 6, and the two wheels 4 may be respectively connected to the rotary drive member 6 for transmission.

[0070] Optionally, the aforementioned rotary drive 6 may be a rotary motor or other rotary drive device.

[0071] Preferably, such as Figure 5As shown, the rotary drive 6 may include an output shaft 61, which can be connected to the wheel 4 via the output shaft 61.

[0072] Optionally, such as Figure 5 As shown, the cross-section of the output shaft 61 can be D-shaped to facilitate transmission connection with the wheel 4. However, it is not limited to this. The transmission connection between the output shaft 61 and the wheel 4 can also be achieved by setting a spline or pin structure.

[0073] Preferably, such as Figure 3 As shown, the drive mounting section 12 may also be provided with a wiring operation section 121, which is located in the middle of the drive mounting section 12 in the first direction F1. The wiring operation section 121 penetrates the side wall of the drive compartment 120 and is connected to the drive compartment 120 so that the drive component 6 can be connected to the battery 3 and the expansion plate 5 described below.

[0074] Preferably, such as Figure 3 As shown, the above-mentioned wiring operation unit 121 may include a second wire hole 1211, which can pass through the side wall of the drive compartment 120 in the second direction F2 along the second direction F2, so as to facilitate the drive unit to the drive connection socket 531 described below.

[0075] Preferably, such as Figure 3 As shown, the above-mentioned connection operation unit 121 may include a maintenance operation port 1212, which can penetrate the top wall of the drive compartment 120 along the gravity direction G, so as to facilitate the inspection and maintenance of the connection lines of the drive unit through the maintenance operation port 1212.

[0076] Optionally, such as Figure 3 As shown, the two sides of the maintenance access port 1212 on the first direction F1 are V-shaped, and the openings of the two sides are arranged opposite to each other to further expand the operating space of the maintenance access port 1212.

[0077] Preferably, such as Figure 3 As shown, the second wire hole 1211 and the maintenance operation port 1212 can be connected to each other to facilitate the space of the second wire hole 1211 and the extended maintenance operation port 1212, thereby facilitating the maintenance and connection operation of the drive component 6.

[0078] Preferably, such as Figure 1 , Figure 2 and Figures 4 to 6As shown, the aforementioned two-wheeled self-balancing scooter may further include an extension plate 5, and the frame assembly may further include multiple support pillars 13, which are fixedly mounted on the top of the counterweight mounting section 11. The extension plate 5 is supported above the counterweight mounting section 11 via the support pillars 13, and the drive mounting section 12 is disposed between the extension plate 5 and the counterweight mounting section 11 to facilitate the assembly and connection of the extension plate 5.

[0079] Preferably, such as Figures 4 to 6 As shown, the aforementioned two-wheeled self-balancing scooter may further include a main control board 7, which is disposed on the side of the extension board 5 opposite to the counterweight mounting part 11. The main control board 7 is communicatively connected to the drive unit and the battery 3 via the extension board 5. Preferably, the drive unit can be electrically connected to the battery 3 to facilitate the transmission of electrical signals, and the extension board 5 can be electrically connected or communicatively connected to the drive unit to transmit control information to the drive unit via the extension board.

[0080] Preferably, such as Figure 6 As shown, the extension plate 5 is detachably connected to the support column 13 to facilitate DIY assembly of the two-wheeled self-balancing scooter and increase its fun.

[0081] Optionally, the extension plate 5 can be threaded to the aforementioned support column 13 via fasteners (e.g., screws, studs, bolts, etc.).

The main control connector 52 and the wiring connector 53 are located at opposite ends of the board body 51. On the one hand, placing the wiring connector 53 at one end of the board body 51 facilitates the connection between the expansion board 5 and the battery 3 and the drive unit 6. On the other hand, placing the main control connector 52 and the wiring connector 53 at opposite ends of the board body 51 not only prevents the main control board 7 from interfering with the connection between the expansion board 5 and the battery 3 and the drive unit 6, but also effectively ensures the uniformity of force on the board body 51, thereby improving the stability of the two-wheeled balance vehicle.

[0083] Preferably, such as Figure 6 As shown, the above-mentioned line plug-in part 53 may also include a drive connection socket 531 and a power connection socket 532, so as to realize the connection between the expansion board 5 and the drive unit 6 through the drive connection socket 531, and the connection between the expansion board 5 and the battery 3 through the power connection socket 532.
