Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle frames, in particular to a multi-dimensional stable frame. Background Art

[0002] The frame is one of the core components of an electric bicycle. It is mainly used to support the body, install the power transmission system, and serve as the installation and fixation basis of other key components. The frame is usually composed of longitudinal beams and cross beams, and is connected to the wheels through the suspension to ensure the overall structural stability and driving safety of the vehicle.

[0003] Traditional frame structures, such as the ladder frame, are known for their excellent stability and load-bearing capacity. The ladder frame adopts a trapezoidal cross-section design, which can better disperse the pressure when bearing vertical loads, improve the stability of the overall structure, and at the same time have good anti-roll performance, ensuring that the vehicle maintains a stable posture when driving at high speeds or making sharp turns.

[0004] At present, most bicycle frames are designed to have corresponding compression support structures, and then reinforced components are installed on the frames along the spatial coordinate axis to achieve a multi-dimensional stable effect. However, with the development of new energy electric vehicles, most multi-dimensional stable frames must also be equipped with corresponding pedal assemblies. The pedal assemblies are connected to the frames through transmission components and can be ridden manually without electricity. However, since the pedal assemblies are generally connected to the frames through bearings, the bearings on most frames are directly exposed to the outside and lack corresponding water-blocking components. This can easily cause water to enter the internal bearings and cause them to rust, affecting the normal assembly and smooth rotation of the subsequent pedals and affecting the use effect. In view of this, we propose a multi-dimensional stable frame. Utility Model Content

[0005] The purpose of the present invention is to provide a multi-dimensional stable frame to solve the defects mentioned in the above background technology.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The utility model provides a water retaining ring and a water retaining plate, and utilizes the water retaining plate to block the outside of the water retaining ring, thereby achieving a preliminary water retaining effect. The water retaining ring is provided in a ring shape, so that the rotating shaft can be assembled normally, and it can also play a certain water retaining effect, making it difficult for water to enter the internal rotating shaft and bearing parts, thereby achieving a certain waterproof protection and preventing rust caused by water ingress.

[0019] 2. The utility model has a ring-shaped water retaining ring, and lubricating oil can be stored between the two water retaining rings. The rotation of the rotating shaft can drive the vertical rod and the horizontal containing cylinder to rotate. The horizontal containing cylinder is used to rotate into the stored oil and contain the oil. As the horizontal containing cylinder rotates to the top of the rotating shaft, the lubricating oil in the liquid storage chamber can flow outward along the discharge hole to the bearing part, thereby achieving a certain lubrication operation on the bearing part and achieving the effect of preventing rust.

[0030] In this embodiment, the inner diameter of the expansion cover 22 increases from the inside to the outside, and the plane of the inner wall of the expansion cover 22 is inclined outward by 5°~15°, so that rainwater dripping on the surface of the expansion cover 22 can better drip down along the surface of the expansion cover 22.

As the horizontal containing cylinder 26 is rotated to the top of the rotating shaft 2, the lubricating oil in the horizontal containing cylinder 26 can flow outward along the discharge hole 28 to the bearing 20, thereby realizing the lubrication operation of the bearing 20.
