Description

Technical Field

[0001] This utility model relates to the field of folding bicycle technology, and in particular to a wire-controlled three-fold power-assisted bicycle. Background Technology

[0002] The cable-controlled folding electric bicycle is a mode of transportation that combines modern technology with convenience. It integrates cable control, folding design, and electric assist, providing users with a more flexible and efficient travel option.

[0003] The main drawback of existing pedal installation technology lies in its lack of quick assembly and disassembly capabilities. Specifically, when a rider encounters an accident such as a crash, the pedal, as a component in direct contact with the ground, is often easily damaged. However, traditional pedals are mostly installed using fasteners such as screws. This installation method is not only cumbersome but also time-consuming, making quick assembly and disassembly impossible. Once a pedal is damaged, riders often find it difficult to replace it in a short time. This not only affects the continuity and safety of riding but also causes unnecessary trouble and losses for riders.

[0004] Therefore, a three-fold power-assisted bicycle with wire control needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire-controlled three-fold power-assisted bicycle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable-controlled folding electric bicycle includes:

[0008] The three-fold bicycle body;

[0009] Both foot pedals are mounted on the three-fold bicycle body;

[0010] Both mounting rods are fixed to the body of the three-fold bicycle, and each mounting rod has a slot, into which the two pedals are respectively inserted.

[0011] Two mounting structures are provided, and both foot pedals are connected to corresponding mounting rods via the mounting structures.

[0012] Two limiting structures are respectively installed on the two mounting rods;

[0013] Two locking mechanisms are respectively installed on the two mounting rods.

[0014] As a preferred embodiment of this utility model, the limiting structure includes:

[0015] Several openings are provided on the mounting rod, and each opening communicates with a slot;

[0016] Several locking beads are respectively movable and set in several openings;

[0017] Several slots are provided on the foot pedal.

[0018] As a preferred embodiment of this utility model, the limiting structure includes:

[0019] A limiting ring is fixed to the mounting rod;

[0020] Several openings are provided on the limiting ring, and each of the several openings is positioned opposite a number of retaining beads.

[0021] As a preferred embodiment of this utility model, the locking structure includes:

[0022] A threaded sleeve is threadedly fitted onto the mounting rod;

[0023] A retaining ring is fixed to one end of the threaded sleeve and is sleeved on the mounting rod.

[0024] As a preferred embodiment of this utility model, the plurality of openings are arranged in a circumferential array.

[0025] As a preferred embodiment of this utility model, the shape of the card bead is adapted to the card slot.

[0026] This utility model has the following beneficial effects:

[0027] Through an innovative design that combines a threaded sleeve and a retaining ring with a locking ball, riders can quickly and easily remove a damaged pedal with a simple rotation, eliminating the need for complex tools or time-consuming disassembly. This design allows the retaining ring, driven by the threaded sleeve, to easily control the movement of the locking ball within the opening, thus enabling rapid separation of the locking ball from the slot. This allows riders to immediately remove the damaged pedal. When installing a new pedal, the same mechanism applies: riders simply insert the pedal into the slot, ensuring the locking ball aligns with the slot, and then rotate the threaded sleeve in the opposite direction. The retaining ring then pushes the locking ball to quickly secure it in the slot, completing a stable pedal installation. The entire process is not only simple and easy but also significantly reduces replacement time, effectively preventing riding interruptions due to pedal damage and ensuring the continuity and safety of the ride.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figure 1-3 A wire-controlled three-fold electric bicycle includes a three-fold bicycle body 1; two pedals 2, both mounted on the three-fold bicycle body 1; and two mounting rods 3, both fixed on the three-fold bicycle body 1. Each mounting rod 3 has a slot, and the two pedals 2 are respectively inserted into the two slots.

[0034] Two mounting structures are provided, and both foot pedals 2 are connected to the corresponding mounting rods 3 through the mounting structures. The limiting structure includes: a plurality of openings 41, all of which are opened on the mounting rods 3, each opening 41 is connected to a slot, and the plurality of openings 41 are arranged in a circumferential array; a plurality of locking beads 42, which are movably disposed in the plurality of openings 41; and a plurality of locking grooves 43, all of which are opened on the foot pedals 2, and the shape of the locking beads 42 is adapted to the locking grooves 43.

[0035] Two limiting structures are respectively set on two mounting rods 3. The limiting structure includes: a limiting ring 51, which is fixed on the mounting rod 3; and several through holes 52, which are all opened on the limiting ring 51, and the several through holes 52 are respectively set opposite to several locking beads 42.

[0036] Two locking structures are respectively set on the two mounting rods 3. The locking structure includes: a threaded sleeve 61, which is threaded onto the mounting rod 3; and a retaining ring 62, which is fixed to one end of the threaded sleeve 61 and is fitted onto the mounting rod 3.

[0037] The specific working principle of this utility model is as follows:

[0038] When the three-fold power-assisted bicycle with wire control proposed in this utility model is used, if the pedal 2 is damaged, the rider can quickly replace the pedal 2. When replacing it, the rider first rotates the threaded sleeve 61. When the threaded sleeve 61 rotates, it can move on the mounting rod 3 and drive the retaining ring 62 to move until the retaining ring 62 separates from the several locking balls 42. Without the restriction of the retaining ring 62, the several locking balls 42 can move within a small range in the corresponding opening 41, which allows the locking balls 42 to be disengaged from the slot 43. Without the restriction of the several locking balls 42, the rider can directly pull the pedal 2 out of the slot.

[0039] When installing pedal 2, the rider inserts pedal 2 into the slot and makes several locking balls 42 respectively engage with several locking slots 43. Further, the rider rotates the threaded sleeve 61 in the opposite direction, causing the threaded sleeve 61 to drive the retaining ring 62 to move until the retaining ring 62 blocks several locking balls 42. When the retaining ring 62 blocks the locking balls 42, the retaining ring 62 can fix several locking balls 42, and the locking balls 42 will be fixed in the locking slots 43. At this time, several locking balls 42 and several locking slots 43 fix pedal 2, realizing the quick installation of pedal 2.

[0040] It is worth noting that a limiting ring 51 is provided on the mounting rod 3. The limiting ring 51 has several through holes 52, and several locking beads 42 extend into the several through holes 52 respectively. The setting of the limiting ring 51 can prevent the locking beads 42 from coming out of the opening 41, while the setting of the through holes 52 ensures that the locking beads 42 can move slightly when separated from the retaining ring 62.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
