Description
Technical Field
[0001] This utility model relates to the field of electric vehicles, and in particular to the fields of electric bicycles, electric mopeds, and electric motorcycles, specifically an automatic steering device. Background Technology
[0002] Currently, the steering devices used in electric bicycles, electric mopeds, and electric motorcycles are operated manually using mechanical mechanisms. The direction of the turn signals is controlled primarily by manually shifting gears. The principle is to connect the circuit through a mechanical switch to power on the turn signals and illuminate them.
[0003] However, riders need to manually shift gears to receive turn signals when changing lanes or turning, which is inconvenient for riding. Therefore, people usually ignore the turn signal operation. Moreover, even if the gear is shifted correctly, the turn signal flashes only on the sides of the vehicle, resulting in a small field of vision and a limited warning area. This makes it difficult for following vehicles to discern the trajectory of the vehicle in front, which can easily lead to traffic accidents. Summary of the Invention

[0040] This utility model proposes an automatic steering device for use in electric non-motorized vehicles. This utility model does not limit the type of electric vehicle, but the structure of the automatic steering device is particularly suitable for electric bicycles, electric mopeds and electric motorcycles.
[0041] In general, the automatic steering device proposed in this utility model mainly includes a front fork riser, a Hall element unit, and a magnet connection unit. See also... Figure 1 It shows the arrangement of the fork riser, Hall element unit and magnet connection unit.
[0042] As mentioned earlier, in order to activate the warning lights during vehicle rotation, a Hall element unit and a magnet connection unit are installed on the handlebars. This enables the automated operation of turning on the lights by rotating the handlebars. The Hall element 2 and magnet 9 in the Hall element unit contact each other, triggering a signal to the control chip PY32F002B. When the control chip PY32F002B receives the signal, it sends DC12V to the lights, which then illuminate and trigger the turn signal lights to work, illuminating the road and alerting pedestrians behind.
[0043] Specifically, such as Figure 1As shown, the front fork stem 1 is vertically arranged, with one end connected to the front fork connecting plate and the other end connected to the handlebar lower stem 5. The end of the handlebar lower stem 5 away from the front fork stem 1 is installed below the vehicle's head cover. A Hall element unit is installed on the handlebar lower stem, and a magnet connecting unit is installed on the front fork stem 1 corresponding to the Hall element unit. The Hall element 2 in the Hall element unit and the magnet 9 in the magnet connecting unit are arranged close to each other. When the handlebar head rotates, it drives the Hall element 2 to rotate, and after it gets close to the magnet 9, it forms contact and obtains a steering signal.
[0044] In use, the Hall element unit rotates with the handlebars, while the magnet connection unit is mounted on the frame and does not rotate. Therefore, it should be specifically noted that the Hall element unit provided in this embodiment includes a handlebar lower stem tube 5, a handlebar lower stem tube bracket 6, and a Hall element 2. The handlebar lower stem tube 5 is sleeved on the end of the fork stem tube 1 away from the head tube 3 of the frame. The handlebar lower stem tube bracket 6 is welded to the side of the handlebar lower stem tube 5 near the magnet connection unit. The Hall element 2 is installed on the top of the handlebar lower stem tube bracket 6, with the detection head of the Hall element 2 facing the magnet connection unit.
[0045] In order to enable the Hall element 2 to be stably installed on the handlebar lower stem tube 5, the lower bracket 6 of the handlebar lower stem tube is set in an L-shape, including a horizontal end 61 and a vertical end 62. The vertical end 62 is vertically welded to the outer surface of the handlebar lower stem tube 5, and the horizontal end 61 is parallel to the axial direction of the handlebar lower stem tube 5. The Hall element 2 is installed on the horizontal end 61.
[0046] Based on this, in order to ensure the stability of signal transmission, on the one hand, the horizontal end 61 of the lower bracket 6 of the handlebar stem extends to the top of the steel cup 4 and is placed as close as possible to the position of the magnet 9 to reduce the signal transmission instability caused by the gap between the two.
[0047] On the other hand, the width of the lower bracket 6 of the handlebar stem should not be greater than the width of the Hall element 2. A suitable bracket width can provide better support, reduce vibration and displacement, ensure that the Hall element remains stable during operation, and at the same time avoid the influence of an excessively large lower bracket 6 of the handlebar stem on signal detection.
[0048] Correspondingly, the magnet connecting unit is provided with a horn connecting bracket 7, a magnet connecting end 8, and a magnet 9. The magnet 9 is installed on the frame head tube 3 through the magnet connecting end 8. The horn connecting bracket 7 is welded to the outside of the frame head tube 3. The horn connecting bracket 7 is located on the side near the steel cup 4. The magnet connecting end 8 is integrally set on the horn connecting bracket 7 near the steel cup 4. The magnet connecting end 8 is integrally bent on one side of the end of the magnet connecting end 8. The magnet connecting end 8 is set perpendicular to the frame head tube 3. The magnet 9 is installed on the magnet connecting end 8.
[0049] Preferably, the horn connecting bracket 7 has a pre-set horn connecting hole 10, which is parallel to the axial direction of the front fork stem tube 1. This provides an effective position for convenient horn installation, improves the installation efficiency of parts, and also assists the turn signal lights, making it convenient to sound a warning bell when an emergency is detected.
[0050] like Figure 3 As shown, an external thread 11 is provided on the outer circumference of the front fork stem tube 1 corresponding to the steel cup 4. The steel cup 4 is installed on the front fork stem tube 1 by rotating the thread. The front fork stem tube 1 achieves the fixing operation of the frame head tube 3 through the steel cup 4, and also achieves the rotation operation of the Hall element 2 through the steel cup 4. In use, the magnet connecting unit rotates with the rotation of the frame head tube 3 and moves closer to or away from the Hall element unit. In order to achieve the relative rotation of the magnet 9 and the Hall element 2 in a reasonable way, the external thread 11 is provided on the front fork stem tube 1 between the Hall element unit and the magnet connecting unit. On the one hand, it can reduce the processing steps of the front fork stem tube 1, and on the other hand, the limited spacing of the external thread 11 can avoid the occurrence of excessive rotation of parts during rotation.
[0051] Based on this, the Hall element unit is preferably connected to the control chip PY32F002B, and the control chip PY32F002B is electrically connected to the lamp installed on the handlebars. The lamp includes an amber turn signal, a flowing arrow light, and a white position light. In actual use, on the one hand, the flowing arrow light illuminates the road surface at a 45° angle. The 45° angle makes the light more easily noticeable to other road users, especially at night or in low light conditions, which enhances riding safety. It can avoid the light shining directly into other people's eyes, reduce glare, protect the vision of others, and improve the safety of the rider.
[0052] On the other hand, the white parking lights illuminate the road surface in the blind spot of the turning area at a 45° angle. The white light is very conspicuous at night or in low light conditions, and the angled illumination can remind other road users of the bicycle's position and driving intention.
[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
