Description

Technical Field

[0001] This utility model relates to the field of gear position sensor technology, and in particular to a resistive motorcycle gear position sensor. Background Technology

[0002] The motorcycle gear position sensor is a key component in the motorcycle electronic control system. Its core function is to detect the current gear position of the gearbox (such as gears 1-6 and neutral, N gear) in real time, and convert the gear position signal into an electrical signal to transmit to the vehicle controller or instrument panel to realize gear position display, shift prompts and coordinated control of the power system. It plays an important role in ensuring riding safety and ease of operation.

[0003] Currently, most mainstream motorcycle gear position sensors on the market use the resistive detection principle. Their basic structure typically includes a mounting base fixed to the engine housing, a trigger component linked to the gear shift mechanism, a circuit board with integrated resistors, and a signal output interface. The trigger component corresponds to different gears via mechanical linkage. When shifting gears, the trigger component conducts with the corresponding resistor on the circuit board, generating different resistance signals, which are then transmitted to the receiving end through the output interface. However, existing sensors often use multi-pin interfaces or multi-wire harness outputs, with each gear corresponding to an independent signal line. This results in a large number of wire harnesses and a messy layout, increasing assembly difficulty and making signal transmission failures prone to occur due to wire harness wear and poor contact. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a resistive motorcycle gear position sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a resistive motorcycle gear position sensor, comprising: a mounting base, a grounding structure, a circuit board, several resistors, a gear position triggering component, and a single-hole signal output component;

[0006] The grounding structure includes a mounting point and a locking nut located on the outside of the mounting base. The mounting point is in contact with the engine housing, and the locking nut passes through the mounting point and is threadedly connected to the engine housing, so that the mounting base is grounded to the engine housing through the mounting point.

[0007] The circuit board is integrated into the inner cavity of the mounting base; the gear trigger assembly includes multiple trigger elements, and the resistors are all soldered to the circuit board, with each resistor electrically connected to a corresponding trigger element of the gear trigger assembly; the gear trigger assembly is disposed within the mounting base, and the trigger elements of the gear trigger assembly correspond to one gear position of the motorcycle; the signal output structure is a single-hole plug, one end of which is electrically connected to the side of the circuit board away from the resistor, and the other end is used to extend outside the mounting base and be detachably electrically connected to the motorcycle's instrument panel or vehicle controller.

[0008] In one embodiment, the gear triggering component includes: an insulating housing, a wiring harness, and a cable tie. The insulating housing is fixed to one side of the mounting base. One end of the wiring harness passes through the insulating housing and extends into the interior of the mounting base, where it is electrically connected to the side of the circuit board away from the resistor. The other end protrudes from the insulating housing, extends outside the insulating housing, and is detachably electrically connected to the motorcycle's instrument panel or vehicle controller. The cable tie securely fastens the wiring harness for tightening it.

[0009] In one embodiment, the insulating housing includes: a first insulating component, a second insulating component, and an insulating tube;

[0010] The first insulating component is a cuboid buckle fixed on the mounting base. The insulating tube is snapped onto the first insulating component, and the wire harness passes through the insulating tube. The second insulating component is a cuboid buckle snapped onto the insulating tube. The cable tie is placed between the first insulating component and the second insulating component to securely fasten the wire harness.

[0011] In one embodiment, the circuit board includes a plurality of contact solder holes;

[0012] The contact welding holes are formed on the circuit board, and the contact welding holes correspond to the elastic contact positions of each trigger element and correspond one-to-one with the resistors; one end of the resistor passes through the contact welding holes and is welded and fixed to the circuit board.

[0013] As can be seen from the above, the resistive motorcycle gear position sensor provided by this utility model significantly simplifies the signal transmission path by using a single-hole signal output component instead of the traditional multi-wire harness structure. This reduces the risk of wire harness wear and poor contact, lowers assembly difficulty, and reduces costs. The trigger element corresponds one-to-one with the motorcycle gear position, effectively improving the stability and wear resistance of the linkage with the gear mechanism and avoiding signal hysteresis or misjudgment. It improves the overall assembly positioning accuracy and vibration resistance. The overall structure is simplified, highly reliable, and has strong environmental adaptability, significantly reducing the failure rate, extending service life, and adapting to the complex operating conditions of motorcycles.

[0022] like Figure 1As shown, a resistive motorcycle gear position sensor is provided, including: a mounting base 1, a grounding structure 2, a circuit board 3, several resistors 4, a gear position triggering component 5, and a single-hole signal output component 6.

[0023] like Figure 2 As shown, the grounding structure 2 includes a mounting point 20 and a locking nut 21 located on the outside of the mounting base 1. The mounting point 20 is in contact with the engine housing, and the locking nut 21 passes through the mounting point 20 and is threadedly connected to the engine housing, so that the mounting base 1 is grounded to the engine housing through the mounting point 20.

[0024] The circuit board 3 is integrated into the inner cavity of the gear trigger assembly 5; the gear trigger assembly 5 includes multiple trigger elements 50, and resistors 4 are all soldered onto the circuit board 3, and each resistor 4 is electrically connected to a trigger element 50 of the gear trigger assembly 5 in a one-to-one correspondence; the gear trigger assembly 5 is set in the mounting base 1, and the trigger elements 50 of the gear trigger assembly 5 correspond to one gear of the motorcycle; the signal output structure 6 is a single-hole plug, one end of the single-hole plug is electrically connected to the side of the circuit board 3 away from the resistor 4, and the other end is used to extend out of the mounting base 1 and be detachably electrically connected to the motorcycle's instrument panel or vehicle controller.

[0025] like Figure 3 As shown, the gear trigger assembly 5 is grounded to the engine via mounting point 20. It includes seven trigger elements 50 corresponding to the 1st, 2nd, 3rd, 4th, 5th, 6th, and Nth gears of the motorcycle. Each trigger element 50 can be linked with the shifting action of the motorcycle gear mechanism. Each trigger element 50 corresponds to a resistor 4. When any trigger element 50 is linked, one end of the trigger element 50 and the corresponding resistor 4 are electrically connected. The other end of all resistors 4 are electrically connected to the common conductive layer of the circuit board 3. One end of the single-hole signal output assembly 6 is electrically connected to the common conductive layer of the circuit board 3, and the other end is used to detach and connect to the signal input terminal of the motorcycle instrument or vehicle controller to output the voltage signal of the corresponding gear.

[0026] The resistance value of resistor 4 varies for each gear level, ensuring that the instrument or controller can accurately identify the voltage signal of different gear levels. Specifically, in one embodiment, the resistance value of resistor 4 corresponding to gear N is 0.36kΩ, that of resistor 4 corresponding to gear 1 is 0.47kΩ, that of resistor 4 corresponding to gear 2 is 1.8kΩ, that of resistor 4 corresponding to gear 3 is 3.24kΩ, that of resistor 4 corresponding to gear 4 is 5.6kΩ, that of resistor 4 corresponding to gear 5 is 12kΩ, and that of resistor 4 corresponding to gear 6 is 47kΩ. In this embodiment, the resistance value of the resistor is not limited to this; any resistor 4 capable of identifying voltage signals of different gear levels is within the scope of this invention.

[0027] Circuit board 3 includes several contact soldering holes 30;

[0028] The contact welding hole 30 is opened on the circuit board 3. The contact welding hole 30 corresponds to the elastic contact position of each trigger 50 and corresponds one-to-one with the resistor 4. One end of the resistor 4 passes through the contact welding hole 30 and is welded and fixed to the circuit board 3.

[0029] In the structure of this novel resistive motorcycle gear position sensor, the contact welding hole 30 refers to the through hole structure opened on the circuit board 3 for realizing the electrical connection between the elastic contact of the gear position trigger 50 and the corresponding resistor 4. It is a key node for the conductive connection between the circuit board 3 and the trigger 50.

[0030] One end of the resistor 4 passes through the contact soldering hole 30 and is soldered to the copper layer of the circuit board 3. At the same time, when the elastic contact of the trigger 50 contacts the resistor 4, the copper line at the contact soldering hole 30 enables the resistor 4 to conduct to the common conductive layer, forming a complete electrical signal circuit.

[0031] This design achieves both mechanical fixation of resistor 4 to circuit board 3 through welding and ensures stable conductivity between the elastic contacts and resistor 4, preventing poor contact due to vibration and wear, and guaranteeing reliable transmission of the gear position signal. Figure 4 As shown, the single-hole signal output assembly 6 includes: an insulating housing 60, a wire harness 61, and a cable tie 62. The insulating housing 60 is fixed to one side of the mounting base 1. One end of the wire harness 61 passes through the insulating housing 60 and extends into the mounting base 1, where it is electrically connected to the side of the circuit board 3 away from the resistor. The other end protrudes from the insulating housing 60, extends out of the insulating housing 60, and is detachably electrically connected to the motorcycle's instrument panel or vehicle controller. The cable tie 62 securely binds the wire harness for tightening it.

[0032] The insulating housing 60 includes: a first insulating component 600, a second insulating component 601, and an insulating tube 602.

[0033] The first insulating component 600 is a cuboid buckle that is fixed on the mounting base 1. The insulating tube 602 is snapped onto the first insulating component 600. The wire harness 61 passes through the insulating tube 602. The second insulating component 601 is a cuboid buckle that is snapped onto the insulating tube 602. The cable tie 62 is placed between the first insulating component 600 and the second insulating component 601 to securely tie the wire harness 61.

[0034] This utility model provides a resistive motorcycle gear position sensor. By using a single-hole signal output component instead of the traditional multi-wire harness structure, it significantly simplifies the signal transmission path, reduces the risk of wire harness wear and poor contact, lowers assembly difficulty, and reduces costs. The trigger element corresponds one-to-one with the motorcycle gear position, effectively improving the stability and wear resistance of the linkage with the gear mechanism and avoiding signal lag or misjudgment. It improves the overall assembly positioning accuracy and vibration resistance. The overall structure is simplified, highly reliable, and has strong environmental adaptability, significantly reducing the failure rate, extending service life, and adapting to the complex operating conditions of motorcycles.
