Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a self-balancing remote control car. Background Technology

[0002] A self-balancing remote-controlled car is a four-wheeled vehicle that, when driven upright, can find its own balance and drive stably on the ground without any third point of support, supported by two wheels.

[0003] Currently, most self-balancing technologies on the market are designed for driving on relatively flat roads or surfaces. I haven't seen any four-wheeled toy cars that can still drive steadily upright after passing through ditches, roadbeds, or steps.

[0004] Based on the above, there is an urgent need to develop a self-balancing remote control vehicle that can adapt to crossing ditches, steps, and complex road conditions, thereby increasing the usability and fun of playing with the self-balancing remote control vehicle. Utility Model Content

[0005] The purpose of this invention is to provide a self-balancing remote control vehicle that can cross ditches, steps, and complex road conditions, thereby enhancing its usability and playability.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A self-balancing remote-controlled car includes a body, a front wheel assembly, and a rear wheel assembly. A gravity balance sensor is installed inside the body. The front wheel assembly and the rear wheel assembly are spaced apart at both ends of the body. The rear wheel assembly includes a rear wheel drive shaft. The distance from the rear wheel drive shaft to the front center of gravity of the body is a first lever arm, and the distance from the fulcrum to the rear center of gravity of the body is a second lever arm. The first lever arm is greater than the second lever arm.

[0008] Preferably, the vehicle body is formed by vacuum forming of a film.

[0009] Preferably, the front wheel component includes a front wheel drive shaft and a front wheel, with both ends of the front wheel drive shaft passing through the vehicle body and each rotatably connected to one of the front wheels, and the front center of gravity of the vehicle body located on the front wheel drive shaft.

[0010] Preferably, the self-balancing remote control vehicle further includes a drive unit, which is connected to the rear wheel drive shaft, and the rear center of gravity of the vehicle body is located at the center of the drive unit.

[0011] Preferably, the rear wheel assembly further includes a rear wheel, and the two ends of the rear wheel drive shaft pass through the vehicle body and are rotatably connected to one of the rear wheels.

[0012] Preferably, both the front wheel and the rear wheel are foam rubber tires.

[0013] Preferably, the driving component is a drive gearbox.

[0014] Preferably, the drive gearbox is a cycloidal gearbox.

[0015] Preferably, the self-balancing remote control vehicle also includes a power supply box, which is installed on the vehicle body and electrically connected to the drive gearbox.

[0016] Preferably, the power supply box is a lithium battery box.

[0017] The beneficial effects of this utility model are as follows: By installing a gravity balance sensor inside the vehicle body, the vehicle body can find its own balance and drive smoothly when it is driving upright. When crossing complex road conditions such as ditches, roadbeds, and steps, it can also maintain its self-balance and not fall over, thereby further increasing the usability and fun of the self-balancing remote control car.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0031] Combination Figures 1 to 3 As shown, this embodiment provides a self-balancing remote control car, including a body 1, a front wheel assembly 2, and a rear wheel assembly 3. The front wheel assembly 2 and the rear wheel assembly 3 are spaced apart at both ends of the body 1. The rear wheel assembly 3 includes a rear wheel drive shaft 31. Using the rear wheel drive shaft 31 as a fulcrum, the distance from the fulcrum to the front center of gravity of the body 1 is the first lever arm, and the distance from the fulcrum to the rear center of gravity of the body 1 is the second lever arm. The first lever arm is greater than the second lever arm. Because the first lever arm is greater than the second lever arm, when a torque is applied to the rear wheel drive shaft 31, the force required to lift the front of the body 1 is less than the force required to lift the rear of the body 1. Therefore, when the self-balancing remote control car transitions from a state where both the front wheel assembly 2 and the rear wheel assembly 3 are on the ground to an upright driving state, the front of the body 1 is more easily lifted, enabling the self-balancing remote control car to perform stunts that switch between horizontal and upright positions, increasing the fun of the self-balancing remote control car.

[0032] Furthermore, a gravity balance sensor (not shown in the figure) is installed inside the vehicle body 1, which allows the vehicle body 1 to find its own balance and drive smoothly when it is driving upright. When crossing complex road conditions such as ditches, roadbeds, and steps, it can also maintain its self-balance and not fall over, thereby further increasing the usability and fun of the self-balancing remote control car.

[0033] Furthermore, the vehicle body 1 is formed from lightweight plastic sheet using vacuum forming, which helps reduce its weight and thus the overall weight of the self-balancing remote control car. When driving upright, its light weight allows the self-balancing remote control car to cross obstacles such as ditches, roadbeds, and steps with better maneuverability and faster speed. In addition, the vacuum-formed body 1 has fewer seams, which improves its strength and durability, enhancing its impact resistance and enabling it to meet more demanding usage conditions. It also simplifies the production process and reduces manufacturing costs.

[0034] Specifically, in this embodiment, reference is made to... Figure 3 As shown, the front wheel component 2 includes a front wheel drive shaft 21 and two front wheels 22. The two ends of the front wheel drive shaft 21 pass through the vehicle body 1 and are rotatably connected to a front wheel 22. The front center of gravity of the vehicle body 1 is located on the front wheel drive shaft 21. Since the front center of gravity of the vehicle body 1 is located on the front wheel drive shaft 21, it is easier to generate the torque required to lift the front wheels 22 during acceleration. This can reduce the tilting or rollover caused by the instability of the front center of gravity, thereby improving the play experience.

[0035] Specifically, in this embodiment, the rear wheel component 3 further includes rear wheels 32. The two ends of the rear wheel drive shaft 31 pass through the vehicle body 1 and are rotatably connected to a rear wheel 32, allowing the self-balancing remote-controlled vehicle to achieve high stability through the combined support and power of the two front wheels 22 and the two rear wheels 32. Furthermore, in the upright driving state, the two rear wheels 32 support the entire vehicle body 1 while also sharing the weight of the entire self-balancing remote-controlled vehicle, resulting in better grip and contributing to better stability of the vehicle body 1, preventing tilting or overturning.

[0036] It should be further noted that in this embodiment, the self-balancing remote control vehicle also includes a drive component 4, which is connected to the rear wheel drive shaft 31. The rear center of gravity of the vehicle body 1 is located at the center of the drive component 4. The drive component 4 is configured to drive the rear wheel drive shaft 31 to rotate, enabling the self-balancing remote control vehicle to directly drive the rear wheel drive shaft 31. This improves the traction of the rear wheel 32, allowing the self-balancing remote control vehicle to more easily cross ditches, steps, and complex road conditions, and better overcome uneven terrain. Furthermore, the direct drive connection of the drive component 4 to the rear wheel component 3 increases the self-balancing remote control vehicle's performance in climbing and other aspects, providing sufficient power to enable it to travel at higher speeds, thus better handling complex terrain.

[0037] Preferably, the drive component 4 is a drive gearbox. Since the meshing between the gears inside the drive gearbox is relatively tight and smooth, the power transmission of the drive gearbox is smoother and the noise is lower. Moreover, the internal structure of the drive gearbox is more compactly connected, which can reduce the production volume of the drive component 4 to a certain extent, reduce the installation space requirements of the drive component 4, and enable the drive component 4 to be better installed inside the vehicle body 1.

[0038] More preferably, in this embodiment, the drive gearbox is a cycloidal gearbox. The cycloidal gearbox has better transmission smoothness and a compact structure, which can well meet the requirements of this embodiment for the driving performance and size of the drive component 4.

[0039] Preferably, in this embodiment, both the front wheel 22 and the rear wheel 32 are made of foamed rubber tires. Foamed rubber tires are relatively lightweight, which further reduces the overall weight of the self-balancing remote-controlled vehicle, improving its maneuverability, speed, and range. Furthermore, foamed rubber tires are typically made of high-density foam material, which has good wear resistance. Compared to traditional tires, foamed rubber tires can effectively extend their service life and better adapt to the self-balancing remote-controlled vehicle's frequent travel on complex terrain. Moreover, this correspondingly improves the grip of the front wheel 22 and the rear wheel 32, facilitating faster travel and obstacle crossing, thus enhancing the vehicle's stability and handling. It should also be noted that foamed rubber tires have excellent shock absorption performance; their internal foam structure effectively absorbs the impact of uneven terrain on the front wheel 22 and the rear wheel 32, making them more durable.

[0040] Optionally, in this embodiment, the self-balancing remote control vehicle also includes a power supply box, which is installed inside the vehicle body 1 and electrically connected to the drive gearbox. The power supply box provides the required electrical energy to the drive gearbox. After the drive gearbox starts working, it transmits power to the rear wheel drive shaft 31, so that the rear wheel 32 receives power and realizes actions such as driving and crossing.

[0041] Preferably, the power supply box in this embodiment is a lithium battery box. Lithium battery boxes have relatively high energy density, enabling them to store more electrical energy in a limited space. This provides power to the drive gearbox for a longer period, allowing the drive gearbox to provide power to the rear wheel drive shaft 31 for an extended time. This results in a longer operating time for the self-balancing remote control vehicle and meets its high power requirements. Furthermore, the lithium battery box is relatively lightweight, which helps improve obstacle-crossing performance. Since the lithium battery box is rechargeable, users can power the self-balancing remote control vehicle using charging equipment, which is not only convenient but also economical.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
