Technical Field
[0001] This utility model belongs to the field of bicycle cable routing technology, and in particular relates to a shared bicycle internal cable routing frame. Background Technology
[0002] Shared bicycles are exposed to complex outdoor environments (sun, rain, and human collisions) for extended periods, and traditional exposed wiring (such as brake cables, gear cables, and electronic lock wiring) has significant drawbacks:
[0003] Vulnerability: Cables are easily pulled, cut, or damaged by external forces, leading to an increased vehicle failure rate.
[0004] Environmental corrosion: Rainwater and dust can seep into cable interfaces, accelerating line aging and causing short circuits in electronic components (such as smart lock malfunctions).
[0005] High maintenance costs: Repairing exposed cables requires frequent disassembly of components, increasing maintenance manpower and time costs.
[0006] Currently, internally cable-guided frames are mostly used in high-end bicycles, but directly applying these frames to shared bicycles presents challenges:
[0007] Cable threading difficulty: Traditional frames rely on manual cable threading, which is inefficient in guiding multiple cables (such as electronic lock power cable, GPS antenna, brake cable) in narrow tubes, and is especially difficult to handle the bends in the downtube and seat tube transition areas.
[0008] Manufacturing and maintenance costs: The split tubing and magnetic traction solutions of high-end bicycles significantly increase the cost of the frame, which does not meet the stringent economic requirements of shared bicycles.
[0009] Therefore, there is an urgent need to design a shared bicycle internal cable routing frame to solve the problems mentioned above. Utility Model Content

[0013] Furthermore, the lower conduit is fixedly connected to the conduit.
[0014] Furthermore, the lower tube and the conduit tube are extruded into a single unit.
[0015] Furthermore, the lower pipe is welded and fixed to the conduit.

[0018] Furthermore, a conduit is inserted through the second threading hole, and the conduit passes through the second threading hole into the lower pipe and the riser pipe, and is connected to the threading pipe.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0030] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This utility model describes a shared bicycle frame with internal cable routing.
[0031] The frame 1 includes a head tube 13, a down tube 11 and a riser tube 14. The head tube 13 is fixedly connected to the down tube 11. The end of the down tube 11 away from the head tube 13 is connected to the riser tube 14. An upper tube 12 is fixedly connected to the head tube 13. The end of the upper tube 12 away from the head tube 13 is connected to the riser tube 14.
[0032] Furthermore, a rear fork 16 is fixedly connected to the riser 14;
[0033] The head tube 13 is used to connect the fork 15 and the handlebars, and the headset bearing is installed inside to enable flexible steering of the handlebars.
[0034] The lower tube 11 is used to bear the tensile / compressive stress during riding.
[0035] The riser 14 is used to install the seat post and saddle, and to adjust the riding height.
[0036] The top tube 12 is used to improve the torsional rigidity of the frame 1 (to prevent the bike from swaying from side to side). In shared bicycles, inclined beams or curved beams are often used to reduce the stride height and make it easier for users of different heights to get on and off the bike.
[0037] The rear fork 16 is used to clamp the rear wheel axle, carry the brake / electronic lock, and install the rear brake caliper and hub electronic lock.
[0038] The front fork 15 is used to clamp the front wheel axle and to mount the front brake caliper.
[0039] Existing internal cable routing frames are difficult to thread, and traditional frames rely on manual threading. Guiding multiple cables (such as electronic lock power cables, GPS antennas, and brake cables) in narrow tubes is inefficient, and it is especially difficult to handle bends in the downtube and seat tube transition areas.
[0040] Existing internal cable routing frames have high manufacturing and maintenance costs, while high-end bikes use separate conduits and magnetic traction solutions that significantly increase frame costs, which do not meet the stringent economic requirements of shared bikes.
[0041] Therefore, the lower tube 11 of this utility model is provided with a conduit 111, and the conduit 111 is provided with a wiring cavity. The electrical wires pass through the wiring cavity. By setting the wiring cavity, multiple electrical wires are protected and hidden. Specifically, the conduit 111 is a smooth pipe, thereby reducing the friction of the electrical wires. The head tube 13 is provided with a first conduit hole 131. The electrical wires pass through the first conduit hole 131 and then enter the wiring cavity. Specifically, the first conduit hole 131 is provided on the top or side of the head tube 13 to allow the electrical wires to enter the interior of the frame 1. The riser tube 14 is provided with a second conduit hole 141. The electrical wires passing through the wiring cavity pass through the second conduit hole 141 to pass out, so as to transmit the electrical wires that pass out of the riser tube 14 to the guide rear wheel area.
[0042] Electrical wiring includes, but is not limited to, electronic lock power cords, GPS antennas, brake cables, etc.
[0043] Preferably, the lower tube 11 is fixedly connected to the conduit 111. In other embodiments of this utility model, other connection methods can also be adopted, such as a slide rail provided on the lower tube 11, which is slidably connected to the conduit 111 through the slide rail, so as to facilitate the replacement of different conduits 111 according to different needs.
[0044] In the first embodiment of the fixed connection between the lower tube 11 and the cable conduit 111, the lower tube 11 and the cable conduit 111 are integrally formed by extrusion molding. The integral strength of the lower tube 11 of the frame 1 is improved by extrusion molding. If the lower tube 11 needs to be bent, the integrally formed lower tube 11 and the cable conduit 111 are bent to the required angle of the frame 1 by bending mold.
[0045] In a second embodiment where the lower tube 11 and the conduit 111 are fixedly connected, the lower tube 11 and the conduit 111 are welded together. The conduit 111 is placed inside the lower tube 11 and then welded together.
[0046] Shared bicycles need to integrate multiple electrical circuits (unlike the 1-2 mechanical wires of ordinary bicycles), and traditional single-cavity wiring is prone to tangling and interference.
[0047] Therefore, a partition 112 is connected inside the wiring cavity, which divides the wiring cavity into multiple independent cavities. Each type of electrical line passes through its corresponding independent cavity. Specifically, there are multiple partitions 112, and the multiple partitions 112 divide the wiring cavity into multiple independent cavities. The specific number of partitions 112 can be determined according to the specific number of electrical lines.
[0048] Preferably, a slide rail is provided inside the wiring cavity, and the partition 112 is slidably connected to the slide rail, so as to divide the corresponding number of independent cavities according to different numbers of electrical lines. In other embodiments of this utility model, the partition 112 can also be fixedly connected to the wiring cavity.
[0049] A conduit 142 is inserted into the second wire hole 141. The conduit 142 passes through the second wire hole 141 into the lower pipe 11 and the riser pipe 14, and is connected to the wire conduit 111. Thus, when wires are threaded, the electrical circuits passing through the wire conduit 111 are transmitted to the outside of the riser pipe 14 through the conduit 142. Specifically, the inner wall of the conduit 142 is made sufficiently smooth.
[0050] Preferably, the angle between the conduit 111 and the conduit 142 is an obtuse angle, so as to facilitate the passage of electrical wires and avoid the effect of electrical wires getting stuck at the connection between the conduit 111 and the conduit 142.
[0051] This utility model eliminates wire cutting and theft by concealing the wiring, reduces vehicle failure rate by 50%, and the 111 conduit's sealed structure blocks rainwater and mud, reducing electronic component failure rate by 45%.
[0052] This invention reduces line resistance by more than 60% by setting up a conduit 111. Compared with traditional bare conduit wiring, it avoids the line getting stuck at welding slag or sharp angles, and improves wiring efficiency by 3 times. Furthermore, an obtuse-angled conduit 142 is set at the bend between the lower conduit 11 and the riser 14 to solve the problem of sharp-angle dead bends, and the wiring success rate is 100%. At the same time, the partition 112 divides the wiring cavity into independent chambers to ensure that the GPS antenna, power line and brake line do not interfere with each other and avoid signal crosstalk.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
