Description

Technical Field

[0001] This utility model relates to the field of electric bicycle frame technology, and in particular to an electric bicycle frame with a cable-covered structure. Background Technology

[0002] The frame of an electric bicycle is not only a supporting structure, but also a key component that integrates the power system and enhances the riding experience. Choosing a well-designed frame can significantly enhance safety, comfort, and overall performance. The battery can be embedded in the downtube or rear rack, and the motor is often integrated into the bottom bracket (mid-mounted motor) or rear wheel hub, making the overall appearance of the bicycle simple and streamlined. The frame materials are more robust, which can better balance the weight of the bicycle. The frame geometry is tuned for electric assist characteristics, taking into account both comfort and efficiency. It is suitable for long-distance, medium-to-high-speed riding and reduces fatigue.

[0003] However, the commonly available electric bicycle frames have some obvious drawbacks: First, the exposed cables not only affect the overall aesthetics of the bicycle, but also, because the cables are directly exposed to external friction and rain erosion, they are prone to problems such as insulation aging and unstable signal transmission, increasing the failure rate and maintenance costs. Second, the manual adjustment of the seat support structure requires manual height adjustment using a wrench or knob, which is cumbersome and has limited precision, making it difficult to quickly adapt to the needs of different riders' body types. Especially when shared or used by multiple family members, frequent manual adjustments significantly reduce the convenience and efficiency of use. Therefore, it is necessary to design an electric bicycle frame with a cable-covered structure. Utility Model Content

[0004] The purpose of this invention is to provide a power-assisted bicycle frame with a cable-covered structure, in order to solve the defects of existing power-assisted bicycle frames that lack a cable-covered mechanism and seat support structure and require manual height adjustment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A power-assisted bicycle frame with a cable-covered structure includes a support column, a square sleeve, a covering device, and an excitation block. One end of a fourth connecting rod is fixedly connected to the support column. A fixing structure is provided on the fourth connecting rod. A power-assisted motor is fixedly connected to the fixing structure. One end of the covering device is fixedly connected to the power-assisted motor. The other end of the covering device is fixedly connected to the support column. A limiting strip is fixedly connected to the inner wall of the covering device. A limiting groove is provided on the limiting strip. An excitation block is engaged in the limiting groove. A sliding block is fixedly connected to the excitation block. One end of a spring is fixedly connected to the sliding block. The other end of the spring is fixedly connected to the limiting block. A servo motor is fixedly connected to the bottom of the support column. A threaded shaft is fixedly connected to the servo motor. The square sleeve is threadedly connected to the threaded shaft.

[0006] As a further technical solution of this utility model, the limiting block is slidably connected to the limiting strip, and the limiting strip is in close contact with the cable structure.

[0007] As a further technical solution of this utility model, a cushion is fixedly connected to the square sleeve.

[0008] As a further technical solution of this utility model, the other end of the fourth connecting rod is fixedly connected to the fixed rod, a rotating rod is rotatably connected to the fixed rod, and a second connecting rod and a reinforcing ring are fixedly connected to the rotating rod.

[0009] As a further technical solution of this utility model, a third connecting rod is fixedly connected to the second connecting rod, and a handle is fixedly connected to the third connecting rod.

[0010] As a further technical solution of this utility model, a front support rod is fixedly connected to the rotating rod, a second fixing block is fixedly connected to the front support rod, and a second connecting through hole is provided on the second fixing block.

[0011] As a further technical solution of this utility model, a first connecting rod is fixedly connected to the support column, a rear support rod is fixedly connected to the first connecting rod, a first fixing block is fixedly connected to the rear support rod, and a first connecting through hole is provided on the first fixing block.

[0012] This utility model provides a power-assisted bicycle frame with a cable-covered structure. Its advantages include: the power-assisted motor provides power to the bicycle, facilitating riding and reducing fatigue; pulling the actuator block upwards causes the sliding block to slide, ultimately pushing the limiting block onto the limiting strip, tightening the limiting strip and thus covering the cable structure. This prevents the cable from being directly exposed to external friction, rain erosion, etc., preventing insulation aging and unstable signal transmission, reducing failure rate and maintenance costs; the servo motor's output rotates, driving the threaded shaft to rotate, which in turn raises and lowers the square sleeve, ultimately adjusting the seat height without the need for manual height adjustment using a wrench or knob. This allows for quick adaptation to different rider body types, significantly improving ease of use and efficiency; the raised edges of the square sleeve prevent rotation, the reinforcing ring strengthens the connection between the rotating rod and the second connecting rod, and the handlebars facilitate steering.

A fixing structure 21 is provided on the fourth connecting rod 22, and a power-assisted motor 11 is fixedly connected to the fixing structure 21. One end of the covering device 10 is fixedly connected to the power-assisted motor 11, and the other end of the covering device 10 is fixedly connected to the support column 1. A limiting strip 25 is fixedly connected to the inner wall of the covering device 10, and a limiting groove 26 is provided on the limiting strip 25. The excitation block 24 is engaged in the limiting groove 26. A sliding block 29 is fixedly connected to the excitation block 24, and one end of a spring 28 is fixedly connected to the sliding block 29. The other end of the spring 28 is fixedly connected to a limiting block 23. A servo motor 2 is fixedly connected to the bottom of the support column 1, and a threaded shaft 7 is fixedly connected to the servo motor 2. The threaded shaft 7 is threadedly connected to the square sleeve 8. The limiting block 23 is slidably connected to the limiting strip 24. 5. The limiting strip 25 is closely attached to the cable structure 27; a seat cushion 9 is fixedly connected to the square sleeve 8; the other end of the fourth connecting rod 22 is fixedly connected to the fixed rod 12, and a rotating rod 13 is rotatably connected to the fixed rod 12.
