Description

Technical Field

[0001] This utility model relates to the field of chassis technology, and in particular to a modular chassis equipped with a hub-mounted motor. Background Technology

[0002] Currently, most electric scooter motorcycles use a one-piece welded frame structure, a traditional design with numerous technical drawbacks. Firstly, in terms of manufacturing, a one-piece welded frame requires complex welding fixtures and subsequent calibration processes. Thermal deformation during production severely affects dimensional accuracy, making it difficult to guarantee product consistency and quality stability. Secondly, regarding maintenance, because the frame is a single unit, any localized damage can render the entire frame unusable, resulting in high repair costs and long repair cycles.

[0003] Furthermore, traditional mid-drive motors often use belt or chain drives, which suffer from significant transmission efficiency losses and require regular adjustments and maintenance. Regarding the suspension system, the connection structure between the traditional rear swingarm and the frame is prone to loosening and fatigue cracks after prolonged use, affecting riding safety. At the same time, the unibody frame structure cannot support users' personalized needs for battery capacity expansion, performance upgrades, etc., limiting the product's sustainable development.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-3 The modular chassis equipped with a hub-mounted motor consists of several different modules, which are connected by bolts to form a complete rigid chassis structure.

[0020] Specifically, the main load-bearing part of the chassis is the support module 1, which is made of high-strength aluminum alloy through extrusion molding. It includes two parallel support plates 11 and a support plate 12 connected to the bottom of the support plates 11, forming a stable U-shaped load-bearing structure. The battery is placed within this structure.

[0021] A front-end module 6 is provided at the front end of the support module 1. The front-end module 6 includes a front tube 61 and a beam 62 connected thereto. A steering column 63 assembly is assembled inside the front tube 61, and a front fork 64 is provided below the steering column 63. A rollable front pulley 65 is provided on the front fork 64. Furthermore, the beam 62 extends rearward and is fixedly connected to the front end of the support module 1 by multiple bolts.

[0022] The rear of the support module 1 is connected to the power module 3 via the adapter module 2. All modules are connected by bolts. The main body of the adapter module 2 has several upward-protruding connecting blocks, which are connected to the seat cushion module 4 by several bolts.

[0023] In this embodiment, the power module 3 adopts a hub-mounted design and includes a connecting part 31 and a drive motor 32. The connecting part 31 is an aluminum alloy casting, which integrates a motor controller and a heat dissipation system. The drive motor 32 is directly mounted on one side of the connecting part 31, and the motor output shaft is directly connected to the rear pulley 33 to form a compact rear fork assembly. This direct-drive design eliminates energy loss in traditional transmission systems and improves transmission efficiency.

[0024] The seat cushion module 4 is located on the upper part of the chassis and is composed of multiple high-strength steel pipes welded together to form a frame 41. The lower part of the frame 41 is fixed to the connecting block on the upper part of the adapter module 2 by bolts, and it is connected to the power module 3 through the connecting rod module 5.

[0025] The linkage module 5 is located between the drive motor 32 and the seat module 4. A shock absorber 51 is installed in the middle of the linkage module 5. The shock absorber 51 is a shock-absorbing spring. The linkage module 5 is mainly responsible for the movement of the shock absorber 51 within its stroke, as well as the connection between it and the chassis and the rear fork assembly.

[0026] All modules are connected using bolts, with anti-loosening designs at critical stress points. The connection surfaces of each module are precision-machined to ensure connection rigidity and positioning accuracy.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
