Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and more specifically, to a novel saddle tube clamp for electric bicycles. Background Technology

[0002] Cycling vehicles (such as bicycles or e-bikes) have become an important tool for short-distance travel as a green, healthy, and environmentally friendly mode of transportation. Shared bicycles, as a type of cycling equipment, have solved the "last mile" problem in urban commutes, offering convenience and environmental friendliness, and have gained widespread popularity in recent years. As is well known, the saddle system is a crucial component of bicycles and other vehicles, directly supporting the rider, and its performance directly affects riding comfort. Currently, to accommodate users of different heights, the saddle tube of the saddle system is mostly an adjustable structure, meaning the saddle tube can be raised or lowered relative to the seat tube and held at an appropriate height by a clamping mechanism. Currently, adjustable saddle systems often use quick-release locking mechanisms; however, for bicycles where saddle height needs frequent adjustments, the quick-release mechanism is prone to fatigue wear, leading to a decrease in clamping strength and compromising the reliability of the saddle tube locking mechanism.

[0003] Secondly, in existing electric bicycles equipped with saddle tube batteries, the power battery is installed inside the saddle tube, which increases the weight of the saddle tube and makes the strength requirements for the saddle tube clamp higher.

[0004] Therefore, providing a saddle post clamp for electric bicycles equipped with saddle post batteries, in order to ensure the locking reliability of the saddle post under repeated, high-frequency use and thus improve riding safety, has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel saddle tube clamp for electric bicycles.

[0006] To address the problems in the background technology, this utility model adopts the following technical solution: A novel saddle post clamp for electric bicycles includes a saddle post clamp body and a handle. The saddle post clamp body has an open ring structure. One end of the saddle post clamp body is provided with a clamp head one, and the other end is provided with a clamp head two. The upper end of the clamp head one is provided with a limiting head, and the upper end of the clamp head two is provided with a reinforcing plate. The sides of the clamp head one and the clamp head two are provided with countersunk nut mounting holes. The side wall of the saddle post clamp body is provided with a saddle post clamp body anti-slip screw mounting hole on the side opposite to the opening. The handle includes a handle rod, a handle rotating head located at both ends of the handle rod, and a handle actuating head. The handle rotating head is provided with a hinge shaft, and the handle has an arc-shaped structure. The main body of the saddle clamp is hinged to the handle by an adjusting nut that passes through clamp one, clamp two and hinge shaft in sequence.

[0007] As a further description of the above technical solution: the outer wall of the saddle clamp body and the inner wall of the saddle clamp body are concentric circles.

[0008] As a further description of the above technical solution: the upper edge of the saddle clamp body is provided with a saddle clamp body mounting limiting boss, and the inner diameter of the saddle clamp body mounting limiting boss is 3.6mm~5mm smaller than the diameter of the inner wall of the saddle clamp body.

[0009] As a further description of the above technical solution: the handle toggle head is provided with a strip-shaped anti-slip groove.

[0010] As a further description of the above technical solution: a saddle clamp anti-slip screw mounting boss is provided on the outer wall of the saddle clamp body on the side opposite to the opening, and the saddle clamp body anti-slip screw mounting hole penetrates the saddle clamp body and the saddle clamp body anti-slip screw mounting boss.

[0011] As a further description of the above technical solution: the other side of the chuck two opposite to the chuck one is an arc-shaped structure, and the diameter of the arc surface of the chuck two is larger than the diameter of the handle rotating head.

[0012] Compared with existing technologies, the advantages of this utility model are: I. The reinforcing plate provided on the main body of the saddle tube clamp of this utility model makes the main body of the saddle tube clamp more robust and durable; II. The saddle tube clamp body of this utility model is fixed to the electric bicycle stem tube by anti-slip screws installed in the anti-slip screw mounting holes of the saddle tube clamp body, making the utility model less prone to slippage during use. Third, the saddle tube clamp body of this utility model is equipped with a limiting head so that the discharge wire will not move with the saddle tube battery shell when adjusting the height of the saddle tube battery shell, thereby solving the problem of easy damage to the discharge wire during use. Fourth, the clamping and loosening of the saddle tube clamp body of this utility model can be completed simply by turning the handle, making it more convenient for users to operate.
