Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of folding scooter technology, and more specifically, to an internally wired electric folding scooter. Background Technology
[0002] With advancements in technology and changes in lifestyles, electric folding scooters, as a convenient, environmentally friendly, and efficient personal transportation tool, have gradually integrated into people's daily lives. They not only possess the flexibility and portability of traditional scooters but also significantly improve riding efficiency and the user experience through electric power.
[0003] However, to achieve a cleaner and more aesthetically pleasing appearance, existing electric folding scooters conceal their wiring harnesses within the folding stem, handlebars, and frame (i.e., internally routed electric folding scooters). Some wiring harnesses need to be installed through the head tube of the frame to the front wheel, while others need to be installed through the head tube and front tube to the pedal body. During the folding and unfolding process of internally routed electric folding scooters, these wiring harnesses often undergo complex bending and stretching movements. Due to the routing requirements of the wiring harnesses in internally routed electric scooters, these harnesses need different routing paths, and the harnesses are prone to friction with the head tube or folding stem when bending, leading to wear on the outer insulation material of the cables and potentially damaging the internal wires. Existing internally routed electric folding scooters cannot simultaneously ensure the bending resistance of the wiring harness while also accommodating the routing of the brake and signal cables within the harness. Utility Model Content
[0004] To address one or more of the technical problems mentioned above, this utility model provides an internally routed electric folding scooter that can ensure the bending resistance of the wiring harness while also taking into account the routing of the brake and signal wires within the wiring harness.
[0005] An internally wired electric folding scooter includes:
[0006] The vehicle body includes a pedal body for the rider to stand on, a front tube connected to the pedal body, and a head tube connected to the front tube;
[0007] Folded riser;
[0008] The handlebars are located at one end of the folding stem;
[0009] The control unit is located on the handlebars;
[0010] The folding device includes a lower folding seat disposed on the head tube and an upper folding seat disposed on the folding upright tube and rotatably connected to the lower folding seat;
[0011] The vehicle body also includes a locking cover disposed in the folding lower seat and used to lock the front fork of the internal cable electric folding scooter, and a fastening bolt that passes through the folding lower seat and the locking cover in sequence and is used to install the folding lower seat onto the locking cover. The fastening bolt is located above the connection position between the front tube and the head tube.
[0012] The internally routed electric folding scooter also includes a spring with one end located in the folding stem and the other end abutting against the fastening bolt, as well as a wiring harness with a brake cable and a signal cable assembly. The brake cable is led out from the controller and passes sequentially through the handlebars, the folding stem, the spring, and the head tube into the front wheel section of the internally routed electric folding scooter. The signal cable assembly is led out from the controller and passes sequentially through the folding stem, the spring, the head tube, and the front tube into the controller of the pedal body.
[0013] Furthermore, the signal line group includes a brake signal line and a turn signal line, and the controller includes a brake assembly and a turn button assembly. One end of the brake signal line is connected to the brake assembly and the other end is connected to the controller. One end of the turn signal line is connected to the turn button assembly and the other end is connected to the controller.
[0014] Furthermore, the handlebars are provided with a first mounting hole for the brake signal line to pass through and a second mounting hole for the turn signal line to pass through, and the end of the folding stem on which the handlebars are mounted is provided with a third mounting hole for the brake line to pass through.
[0015] Furthermore, the front fork is provided with a fourth mounting hole through which the brake cable passes.
[0016] Furthermore, the upper folding seat is provided with a first connecting hole, and the lower folding seat is provided with a second connecting hole. The first connecting hole and the second connecting hole are rotatably connected by bolts or pins.
[0017] Furthermore, the outer diameter of the spring is 1mm-2mm smaller than the inner diameter of the locking cover.
[0018] Furthermore, the length of the spring within the locking cover is 1 / 5 to 1 / 7 of the length of the head tube.
[0019] Furthermore, the length of the spring located inside the folding riser is greater than the length of the spring located inside the locking cover.
[0020] Furthermore, the internally routed electric folding scooter also includes a locking assembly rotatably connected to the folding lower seat and an anti-detachment hook provided on the folding upright tube. When the internally routed electric folding scooter is in the folded state, the anti-detachment hook is disengaged from the locking assembly. When the internally routed electric folding scooter is in the unfolded state, the anti-detachment hook is engaged in the locking assembly.
[0021] Furthermore, the locking assembly includes a rotating handle rotatably connected to the folding lower seat, a push-pull pin passing through the rotating handle, and an anti-loosening buckle fixed on the push-pull pin. The anti-loosening pin can push the anti-loosening buckle to move along the axial direction of the push-pull pin so that the anti-loosening buckle engages with the anti-loosening pin.
[0022] The internally routed electric folding scooter provided in this embodiment has a brake cable that originates from the controller and passes sequentially through the handlebars, folding stem, spring, and head tube before entering the front wheel. This allows the controller to control the front wheel's braking, forming a closed-loop braking control system. The signal cable also originates from the controller and passes sequentially through the folding stem, spring, head tube, and front tube before entering the pedal body. This transmits signals from the controller to the pedal body's controller, ensuring reliable signal transmission. A rotating connection between the folding lower seat and the folding lower seat allows the folding stem to rotate relative to the head tube, enabling the scooter to switch between folded and unfolded states. A spring, with one end located in the folding stem and the other end abutting against a fastening bolt on the scooter body, can be fitted over the wiring harness when the folding stem rotates relative to the head tube. This protects the exposed wiring harness between the folding stem and head tube during the folding / unfolding transition, reducing the likelihood of damage during bending. More importantly, since one end of the spring rests against the fastening bolt located above the connection between the front tube and the head tube, this arrangement ensures that the brake cable is guided into the front wheel system along the optimal path inside the head tube. On the other hand, it provides a non-interfering channel between the head tube and the front tube for the signal cable group. Thus, while ensuring the bending resistance of the wiring harness, it also takes into account the routing and layout of the brake cable and the signal cable group in the wiring harness.

[0040] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0041] Figure 1This diagram illustrates the structure of the internally routed electric folding scooter provided in this embodiment. Figure 2 It shows Figure 1 A magnified view of a portion of point A in the middle. Figure 3 A cross-sectional view of the internally routed electric folding scooter provided in this embodiment is shown. Figure 4 It shows Figure 3 A magnified view of a section at point B. (See image below.) Figures 1-4 As shown, this embodiment provides an internally routed electric folding scooter, including a frame 1, a folding stem 2, handlebars 3, a controller 4, a folding mechanism 5, a spring 6, and a wiring harness 7. The frame 1 includes a footrest body 11 for the rider to stand on, a front tube 12 connected to the footrest body 11, and a head tube 13 connected to the front tube 12. The handlebars 3 are located on one end of the folding stem 2. The controller 4 is located on the handlebars 3. The folding mechanism 5 includes a folding lower seat 51 located on the head tube 13 and a folding upper seat 52 located on the folding stem 2 and rotatably connected to the folding lower seat 51. The frame 1 also includes a locking cover 14 located inside the folding lower seat 51 for locking the front fork 8 of the internally routed electric folding scooter, and fastening bolts 15 that pass sequentially through the folding lower seat 51 and the locking cover 14 for mounting the folding lower seat 51 onto the locking cover 14. The fastening bolts 15 are located above the connection point between the front tube 12 and the head tube 13. The internally routed electric folding scooter also includes a spring 6 with one end located in the folding stem 2 and the other end abutting against the fastening bolt 15, as well as a wiring harness 7 having a brake cable 71 and a signal cable group 72. The brake cable 71 is led out from the controller 4 and passes through the handlebars 3, the folding stem 2, the spring 6, and the head tube 13 in sequence to enter the front wheel part of the internally routed electric folding scooter. The signal cable group 72 is led out from the controller 4 and passes through the folding stem 2, the spring 6, the head tube 13, and the front tube 12 in sequence to enter the controller of the pedal body 11.
[0042] In this embodiment, the internally routed electric folding scooter features a brake cable 71 that originates from the controller 4 and sequentially passes through the handlebars 3, folding stem 2, spring 6, and head tube 13 before entering the front wheel. This allows the controller 4 to control the front wheel for braking, forming a closed-loop braking control system. A signal cable group 72 originates from the controller 4 and sequentially passes through the folding stem 2, spring 6, head tube 13, and front tube 12 before entering the pedal body 11. This relays signals from the controller 4 to the controller in the pedal body 11, ensuring reliable signal transmission. The folding lower seat 51 is rotatably connected to the folding lower seat 51, allowing the folding stem 2 to rotate relative to the head tube 13, thus enabling the switching between the folded and unfolded states of the internally routed electric folding scooter. The spring 6, with one end located in the folding stem 2 and the other end abutting against the fastening bolt 15 of the vehicle body 1, can be sleeved on the outside of the wiring harness 7 when the folding stem 2 rotates relative to the head tube 13. This protects the exposed wiring harness 7 between the folding stem 2 and the head tube 13 when the internally routed electric folding scooter switches between folded and unfolded states, thereby reducing the possibility of damage to the wiring harness 7 when bending. More importantly, since one end of the spring 6 abuts against the fastening bolt 15 located above the connection position between the front tube 12 and the head tube 13, this arrangement ensures that the brake cable 71 is guided into the front wheel system along the optimal path inside the head tube 13. On the other hand, it provides a non-interfering channel between the head tube 13 and the front tube 12 for the signal cable group 72. Thus, while ensuring the bending resistance of the wiring harness 7, it also takes into account the routing layout of the brake cable 71 and the signal cable group 72 within the wiring harness 7.
[0043] Specifically, signal line group 72 includes a brake signal line 721 and a steering signal line 722. The controller 4 includes a brake assembly 41 and a steering button assembly 42. One end of the brake signal line 721 is connected to the brake assembly 41, and the other end is connected to the controller, allowing the rider to engage or disengage the brake assembly 41 to send a braking signal to the controller. One end of the steering signal line 722 is connected to the steering button assembly 42, and the other end is connected to the controller, allowing the rider to manipulate the steering button assembly 42 to send a steering signal to the controller.
[0044] It should be noted that the controller can be understood as a light signal control module or a multi-functional signal integrated controller in the prior art. It is triggered by the brake assembly 41 and the turn button assembly 42, and coordinates the opening and closing of the brake lights and turn signals of the internally routed electric folding scooter. Given that the specific configuration of the controller is a mechanical structure widely recognized by those skilled in the art, it will not be described in detail here to avoid redundancy. Only the necessary textual description is provided to ensure that those skilled in the art can effectively implement it based on this information.
[0045] Furthermore, a first connecting hole is provided on the upper folding seat 52, and a second connecting hole is provided on the lower folding seat 51. The first connecting hole and the second connecting hole are rotatably connected by bolts or pins, thereby enabling the switching between the folded and unfolded states of the internally wired electric folding scooter.
[0046] Furthermore, the handlebar 3 has a first mounting hole 31 for the brake signal line 721 to pass through and a second mounting hole 32 for the turn signal line 722 to pass through. The end of the folding stem 2 where the handlebar 3 is mounted has a third mounting hole 21 for the brake line 71 to pass through. This allows longer brake signal lines 721, turn signal lines 722, and brake lines 71 to be hidden in the handlebar 3 and folding stem 2 when they are inserted into the scooter. This prevents the brake signal lines 721, turn signal lines 722, and brake lines 71 from getting tangled around the rider's feet or affecting riding stability during riding, thus improving riding safety and making the scooter more streamlined and sleek overall.
[0047] Furthermore, the front fork 8 is provided with a fourth mounting hole 81 through which the brake cable 71 passes, so that a longer brake cable 71 can be hidden in the head tube 13 and the front fork 8 when it passes through the front fork 8, making the scooter more concise and streamlined overall.
[0048] Furthermore, the outer diameter of the spring 6 is 1mm-2mm smaller than the inner diameter of the locking cover 14. This facilitates the installation of the spring 6 inside the locking cover 14 and also allows the end of the spring 6 that abuts against the fastening bolt 15 to abut against the inner wall of the locking cover 14 when it is bent by the folding tube 2, thereby preventing the spring 6 from coming out of the locking cover 14.
[0049] Furthermore, the length of the spring 6 inside the locking cover 14 is 1 / 5 to 1 / 7 of the length of the head tube 13, so as to increase the routing space for the brake line 71, brake signal line 721 and turn signal line 722 while ensuring that the spring 6 has a protective function.
[0050] Furthermore, the length of the spring 6 inside the folding tube 2 is greater than the length of the spring 6 inside the locking cover 14, so as to avoid the folding tube 2 rotating too much relative to the head tube 13, causing one end of the spring 6 in the folding tube 2 to come out, so that when switching from the folded state to the unfolded state, the spring 6 still needs to be compressed.
[0051] Figure 5 A schematic diagram of the structure of the folding riser 2, the locking assembly 9, and the anti-detachment hook 10 provided in this embodiment is shown. Figure 5 and combined Figures 1-4As shown, the internally routed electric folding scooter also includes a locking assembly 9 rotatably connected to the folding lower seat 51 and an anti-detachment hook 10 provided on the folding upright tube 2. When the internally routed electric folding scooter is in the folded state, the anti-detachment hook 10 disengages from the locking assembly 9, allowing the internally routed electric folding scooter to be easily folded and stored. When the internally routed electric folding scooter is in the unfolded state, the anti-detachment hook 10 is engaged in the locking assembly 9 to ensure the structural stability of the internally routed electric folding scooter and improve safety and stability during use.
[0052] Specifically, the locking assembly 9 includes a rotating handle 91 rotatably connected to the folding lower seat 51, a push-pull pin 92 passing through the rotating handle 91, and an anti-loosening buckle 93 fixed on the push-pull pin 92. The anti-detachment pin 10 can push the anti-loosening buckle 93 to move along the axial direction of the push-pull pin 92 so that the anti-loosening buckle 93 engages with the anti-detachment pin 10, thereby realizing the engagement or disengagement of the anti-detachment pin 10 with the locking assembly 9, and thus realizing the switching between the folded state and the unfolded state of the internally wired electric folding scooter.
