Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, specifically to a four-wheel drive waterproof electric scooter. Background Technology

[0002] With the increasing popularity of short-distance urban travel and outdoor recreational activities, electric scooters have become an important mode of transportation due to their lightweight and agile characteristics. However, traditional electric scooters mostly use single or dual motors, resulting in limited power output. Furthermore, their suspension systems are often rigid connections or simple spring structures, leading to poor passability, stability, and comfort on unpaved surfaces (such as gravel, mud, and bumpy roads). In addition, ordinary electric scooters lack sufficient waterproofing, making them unsuitable for humid or rainy environments, further limiting their application scenarios. To overcome these shortcomings, there is an urgent need to develop a new type of electric scooter that can achieve high performance in both off-road and urban conditions through innovative design. Utility Model Content

[0003] This utility model provides a four-wheel drive waterproof electric scooter. Through systematic optimization, it solves the pain points of traditional electric scooters in terms of power, suspension, and waterproofing, and is suitable for various scenarios such as commuting, off-roading, and outdoor entertainment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a four-wheel drive waterproof electric scooter, comprising: a board body, a battery control box fixedly disposed at the bottom of the board body, and a steering drive unit connected to both ends of the board body and the battery control box; the steering drive unit includes an upper body fixedly disposed below the end of the board body, and a lower body hinged to the lower part of the upper body; drive motors are respectively provided on both sides of the lower body, and each drive motor is electrically connected to the battery control box through a wire passing through the upper body; the steering drive unit includes upper forks hinged to both sides of the upper body, and lower forks hinged to both sides of the lower body, with horns connected between the free ends of the upper and lower forks via ball joints, each horn having a penetrating axle head, and the outer end of the axle head being connected to a wheel hub, the inner end of the axle head being connected to the corresponding drive motor via a half-shaft; a steering tie rod is also hinged between one side of each horn and the lower body; a shock absorber is provided between the middle of each lower fork arm and the lower body.

[0005] Preferably, the upper body has a window in the middle, the lower body has a lamp holder extending upward through the window, and the top of the shock absorber is hinged to the corresponding end of the lamp holder.

[0006] Preferably, each of the drive motors has a small pulley on its output shaft; large pulleys are provided on both sides of the middle part of the lower body, and each of the large pulleys is driven by a synchronous belt to the corresponding small pulley.

[0007] Preferably, the shaft head is connected to the half shaft via a transmission cup, and the other end of the half shaft is connected to the large pulley via a ball joint.

[0008] Preferably, steering springs are longitudinally arranged between the two sides of the lower main body and the plate.

[0009] Preferably, the battery control box has a PCB shell on each side, and each of the PCB shells has a charging interface and a power switch.

[0010] The beneficial effects of this invention are as follows: Four drive motors drive each wheel hub via synchronous belt transmission, achieving true four-wheel drive force distribution. This improves driving capability on unpaved roads. Furthermore, the drive plate inside the battery control box optimizes the power distribution between wheels, enhancing stability on slippery / rough roads. Even when a single motor fails, basic driving capability is maintained. The upper and lower wishbones, along with the steering knuckle, form a double wishbone structure, suppressing wheel roll. Combined with the shock absorbers absorbing road impacts, the suspension travel is large, adapting to bumpy roads and improving cornering stability. The steering tie rod, linked to the steering knuckle, enables wheel steering. The steering spring assists in centering the wheel, reducing user fatigue and improving steering feel. The top of the shock absorber connects to the light fixture, saving space, optimizing the spatial layout, and lowering the center of gravity. The CV joint connects the half-shaft and the large pulley, allowing uninterrupted power transmission during wheel bounce. The transmission cup ensures a reliable connection between the axle and the half-shaft, achieving efficient transmission, reducing power loss, and adapting to dynamic suspension changes. Additionally, the universal joint design reduces wear and extends lifespan. The sealed battery control box and PCB casing support use in rainy or lightly wet conditions. Furthermore, the modular circuit layout facilitates maintenance and upgrades. This four-wheel-drive waterproof electric scooter addresses the pain points of traditional electric scooters in terms of power, suspension, and waterproofing through systematic optimization. It is suitable for both urban streets and unpaved roads, making it applicable to various scenarios such as commuting, off-roading, and outdoor recreation. Its waterproof design, comfortable shock absorption, and agile steering further expand its usage scenarios and target audience. Attached Figure Description
