Two front wheel tilting vehicle

Abstract

The present invention provides a two front wheel tiltable vehicle, comprising a tilting unit, two front wheels which are pivotally arranged on the tilting unit and can be tilted by the tilting unit, a control switch which can be operated by a user to generate a conduction signal, a warning light, and a tilting controller which is used to receive the conduction signal of the control switch. The tilting controller can transmit an execution signal to the tilting unit to lock or unlock the tilting unit. When the vehicle power is turned on, if the tilting controller detects that the conduction signal lasts for a predetermined time, the tilting controller determines that the control switch is abnormal, and stops the transmission of the signal to avoid the vehicle from being unlocked and causing safety problems such as vehicle tilting when the vehicle power is turned on. The tilting controller also controls the warning light to turn on to remind the user to troubleshoot.

Description

Technical Field

[0001] This invention relates to a three-wheeled motorcycle, and more particularly to a vehicle with two tiltable front wheels. Background Technology

[0002] A typical motorcycle usually has only one front wheel and one rear wheel on the same axle. While this design gives motorcycles the advantages of being more maneuverable and lighter, it also makes it difficult to maintain balance. Therefore, whether riding or parking, the rider must rely on their own skills to maintain the balance of the motorcycle to avoid tipping over. This is especially true when pulling the motorcycle out of a parking area crowded with other vehicles, as it is often difficult to maintain balance due to the lack of points of leverage.

[0003] In light of this, three-wheeled motorcycles with two front wheels, as disclosed in Taiwan Patent No. TWI346055, have appeared on the market. These motorcycles have two front wheels on either side, and a linkage allows the two front wheels to tilt relative to the motorcycle, ensuring the motorcycle's turning ability. However, maintaining this tilting capability at all times would cause the same imbalance problem as a typical two-wheeled motorcycle when parking. Therefore, many three-wheeled motorcycles have locking and unlocking switches on the handlebars, allowing users to lock or unlock the linkage as needed to control whether the motorcycle can tilt.

[0004] However, the locking and unlocking switches that control the vehicle's tilt function can short-circuit or become stuck, potentially causing incorrect signals that trigger the locking or unlocking functions. This is especially true if the unlocking switch is short-circuited or stuck before the user starts the vehicle; it will unlock the tilt function the instant the power is turned on, causing the vehicle to tilt. If the user doesn't react in time, this could result in the vehicle tipping over or injury. Similarly, repeated accidental activation of the locking switch can make it difficult for the user to turn the vehicle while pulling it, or prevent the tilt function from being activated smoothly while riding. Summary of the Invention

[0005] [The problem that the invention aims to solve]

[0006] Therefore, the object of the present invention is to provide a vehicle capable of detecting switch errors.

[0007] [Technical means to solve the problem]

[0008] Therefore, the present invention provides a vehicle with tiltable front wheels, comprising a tilting unit, two front wheels pivotally mounted on the tilting unit at left-right intervals and tiltable by the tilting unit, a control switch operable by a user to generate a communication signal, a warning light, and a tilt controller for receiving the communication signal from the control switch. The tilt controller can transmit an execution signal to the tilting unit to lock or unlock it. When the vehicle is powered on, if the tilt controller detects that the communication signal persists for a predetermined time, the tilt controller determines that the control switch is malfunctioning, stops transmitting the execution signal, and controls the warning light to illuminate.

[0009] In some embodiments of the present invention, when the tilt controller detects that the communication signal is disconnected and this continues for a certain period of time, the tilt controller determines that the control switch has returned to normal and controls the warning light to turn off.

[0010] In some embodiments of the present invention, the vehicle further includes an alarm sound element that is signal-connected to the tilt controller. When the execution signal is an unlock signal and the tilt controller determines that the control switch is malfunctioning, the tilt controller controls the alarm sound element to generate an alarm sound for an operating time. If the tilt controller determines that the control switch has returned to normal within the operating time, the tilt controller stops the alarm sound from the alarm sound element. If the operating time is exceeded and the tilt controller still determines that the control switch is malfunctioning, the tilt controller sends an unlock signal to the tilt unit to unlock the tilt unit.

[0011] In some embodiments of the present invention, the vehicle further includes an engine control unit that can detect engine speed and is signal-connected to the tilt controller, and an anti-lock braking control unit that can detect wheel speed and is signal-connected to the tilt controller. When the engine control unit detects that the engine speed is greater than 2200 rpm and the anti-lock braking control unit detects that the wheel speed is greater than 2 km / h, it will cause the tilt controller to send an unlocking signal to the tilt unit to unlock the tilt unit.

[0012] In some embodiments of the present invention, the vehicle further includes an engine control unit that can detect engine speed and is signal-connected to the tilt controller. When the engine control unit detects that the engine speed is greater than 3000 rpm, it causes the tilt controller to send an unlock signal to the tilt unit to maintain the tilt unit in an unlocked state.

[0013] In some embodiments of the present invention, the vehicle further includes an engine control unit that can detect engine speed and is signal-connected to the tilt controller. When the execution signal is a lock signal and the engine control unit detects that the engine speed is greater than 3000 rpm, the tilt controller stops transmitting the lock signal.

[0014] In some embodiments of the present invention, the tilting unit includes two horizontal bars spaced apart vertically, two side bars spaced apart horizontally and pivotally connected to the two horizontal bars, two shock absorbers respectively connected to the two side bars and the two front wheels, a tilt locker connected to the two horizontal bars, two travel lockers respectively disposed on the two shock absorbers, and a transmission mechanism that receives the execution signal of the tilt controller to lock or unlock the tilt locker and the travel locker.

[0015] In some embodiments of the present invention, the transmission mechanism includes a hydraulic pump that links the tilt lock and the two stroke locks, a cam that can be driven by transmission to drive the hydraulic pump, and a drive motor that can receive the execution signal of the tilt controller to drive the cam.

[0016] In some embodiments of the present invention, the transmission mechanism includes a hydraulic pump that links the two stroke locks, a cam that can be driven by transmission to drive the hydraulic pump, a drive motor that can receive the execution signal from the tilt controller to drive the cam, and an auxiliary motor that can receive the execution signal from the tilt controller to control the tilt locks.

[0017] In some embodiments of the invention, the tilt lock has a connector connecting the two crossbars and a clamp that can be controlled by the auxiliary motor to clamp the connector.

[0018] In some embodiments of the present invention, the control switch is a spring-loaded reset switch and includes an unlock switch and a lock switch. Pressing the unlock switch can trigger an unlock signal to unlock the tilting unit, and pressing the lock switch can trigger a lock signal to lock the tilting unit. The control switch will reset after being pressed and will not emit the signal.

[0019] [The effects of the invention]

[0020] In the vehicle with tiltable front wheels of the present invention, the tilt controller can actively detect whether the control switch is stuck or short-circuited and continues to generate the conduction signal after the vehicle power is turned on. When it is determined that the control switch is abnormal, the tilt controller will prevent the unlocking or locking of the tilt unit from continuing to be issued, so as to avoid safety problems such as the vehicle tipping over when the vehicle power is turned on. The controller will also make the warning light light up or flash to remind the user to troubleshoot the fault, or to provide a reference for repairmen when troubleshooting the fault.

[0021] In some embodiments of the invention, the tilt controller continuously monitors the control switch to determine whether the user has troubleshooted the problem (or whether the control switch has been automatically reset).

[0022] In some embodiments of the present invention, when the unlocking function of the control switch malfunctions, in addition to the warning light, the warning sound element will also generate a voice or sound to further remind the user that the unlocking function is malfunctioning. When the aforementioned warning sound exceeds the operating time, the tilt control switch will automatically unlock the tilting unit to avoid the problem that the user cannot tow the vehicle for repairs because the tilting unit is locked.

[0023] In some embodiments of the present invention, when the engine speed is greater than 2200 rpm and the wheel speed is greater than 2 km / h, usually at the start of a driving cycle when the green light is on, the tilt controller will automatically unlock the tilt unit to facilitate steering operations during driving.

[0024] In some embodiments of the present invention, when the engine speed is greater than 3000 rpm, the tilt controller will automatically unlock the tilt unit and stop transmitting the locking signal to avoid locking the tilt unit due to accidental activation of the control switch while driving, thus ensuring driving safety.

[0025] In some embodiments of the present invention, the detailed structure and configuration of the tilting unit of the vehicle are described.

[0026] In some embodiments of the present invention, another detailed structure and configuration of the tilting unit of the vehicle is described.

[0062] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0063] See Figure 1 and Figure 2 A first embodiment of the present invention, a vehicle with two tiltable front wheels, includes a tilting unit 1, two front wheels 2 pivotally mounted on the tilting unit 1 at left and right intervals, a control switch 3 disposed on the handlebars of the vehicle for user operation by pressing, a tilt controller 4 connected to the control switch 3, a warning light 5 connected to the tilt controller 4, a warning sound element 6 connected to the tilt controller 4 and capable of emitting a warning sound, an engine control unit 7 capable of detecting engine speed and connected to the tilt controller 4, and an anti-lock brake control unit 8 capable of detecting wheel speed and connected to the tilt controller 4.

[0064] The tilting unit 1 includes two horizontal bars 11 spaced vertically from each other, two side bars 12 spaced horizontally from each other and pivotally connected to the two horizontal bars 11, two shock absorbers 13 respectively connecting the two side bars 12 and the two front wheels 2, a tilt lock 14 connecting the two horizontal bars 11, two travel locks 15 respectively disposed on the two shock absorbers 13, and a transmission mechanism 16 that links the tilt lock 14 and the travel locks 15. The two horizontal bars 11 and the two side bars 12 constitute a linkage mechanism that can tilt left and right. By tilting the two side bars 12 relative to the two horizontal bars 11, the two shock absorbers 13 and the two front wheels 2 (i.e., the right front wheel 21 and the left front wheel 22) can be tilted left and right. In this first embodiment, the tilt lock 14 is a hydraulic cylinder connected to the two side rods 12. It generates a stopping force by injecting hydraulic oil, preventing the two side rods 12 from tilting relative to the two crossbars 11, thus achieving the function of locking the tilt. Conversely, when no hydraulic oil is injected into the tilt lock 14, the two side rods 12 can still push the tilt lock 14 to tilt relative to the two crossbars 11, thus achieving the function of unlocking the tilt. The two stroke locks 15 can be used to control the two shock absorbers 13 to prevent the shock absorbers 13 from experiencing excessive lifting and lowering, resulting in a near-tilt situation. The transmission mechanism 16 includes a hydraulic pump 161 that links the tilt lock 14 and the two stroke locks 15, a cam 162 that can be driven by transmission to drive the hydraulic pump 161, and a drive motor 163 that is controlled by the tilt controller 4 to drive the cam 162. The drive motor 163 can drive the cam 162 to actuate, thereby pushing the hydraulic pump 161 or reducing the hydraulic pressure of the hydraulic pump 161 to zero, and thus actuating the tilt lock 14 and the two stroke locks 15.

[0065] See Figures 1 to 4The control switch 3 is a spring-loaded reset switch and can generate a signal upon operation. The control switch 3 includes a locking switch 31 and an unlocking switch 32. The locking switch 31 and the unlocking switch 32 can be connected and operated in tandem, or they can be two independent switches that are not interconnected. Pressing the locking switch 31 triggers a locking signal to lock the tilting unit 1, and pressing the unlocking switch 32 triggers an unlocking signal to unlock the tilting unit 1. Under normal circumstances, the control switch 3 will reset after being pressed and will no longer generate a signal. The tilt controller 4 receives the signal from the control switch 3 and can transmit an execution signal to the drive motor 163 based on the signal, causing the drive motor 163 to drive the cam 162 to switch between two positions, thereby controlling the hydraulic pump 161 to unlock or lock the two stroke locks 15 and the tilt lock 14. In this first embodiment, the tilt controller 4 uses a current sensor to sense whether the current value of the drive motor 163 exceeds a threshold to confirm whether the drive motor 163 is stalled, and uses a cam position sensor to sense the position of the cam 162 to confirm whether the cam 162 has rotated to the correct position, thereby determining whether the tilt lock 14 and the two travel locks 15 are in an unlocked or locked state. The engine control unit 7 (ECU) is connected to the tilt controller 4 via a communication interface signal and can provide the tilt controller 4 with the detected engine speed. The anti-lock braking control unit 8 (ABS) is also connected to the tilt controller 4 via a communication interface signal and can provide the tilt controller 4 with the detected wheel speed.

[0066] See Figure 2 , Figure 5 ,and Figure 6The following describes the monitoring function of the tilt controller 4: When the vehicle's power is turned on, the tilt controller 4 receives a signal from the power switch and begins detection. If the tilt controller 4 detects that the conduction signal of the control switch 3 is continuous and exceeds a predetermined time, it will determine that the control switch 3 is malfunctioning and stop transmitting the corresponding execution signal. For example, if a locking conduction signal is detected continuously, the transmission of the locking execution signal will be stopped to temporarily suspend the locking function. The tilt controller 4 will also control the warning light 5 to illuminate to remind the user to troubleshoot the problem as soon as possible. Next, the tilt controller 4 will continue to detect to determine whether the problem has been resolved. When it detects that the conduction signal is disconnected and continues for more than a certain judgment time, the tilt controller 4 will determine that the control switch 3 has returned to normal and will control the warning light 5 to turn off. At this time, if the control switch 3 is operated and generates the conduction signal, the tilt controller 4 can transmit the corresponding execution signal to the drive motor 163 according to the conduction signal. The aforementioned function can actively detect whether the control switch 3 is stuck or short-circuited and continues to generate the conduction signal after the vehicle power is turned on. When it is determined that the control switch 3 is abnormal, the tilt controller 4 will prevent the execution signal for locking or unlocking the tilt unit 1 from continuing to be issued, so as to avoid safety problems such as the vehicle tipping over when the vehicle power is turned on. The warning light 5 will be lit or flashed to remind the user to troubleshoot the problem, or to provide a reference for repairmen when troubleshooting. In this first embodiment, both the predetermined time and the judgment time are 0.5 seconds, but are not limited to this.

[0067] See Figure 2 , Figure 5 ,and Figure 7When the unlock switch 32 is determined to be malfunctioning (i.e., the communication signal is the unlock signal), the tilt controller 4, in addition to illuminating the warning light 5, will also cause the warning sound element 6 to emit a warning sound for a duration (in this first embodiment, the warning sound element 6 is a buzzer). If, within this duration, the tilt controller 4 determines that the unlock switch 32 has returned to normal, the tilt controller 4 will turn off the warning light and stop the warning sound element 6. At this time, when the user presses the control switch 3, the tilt controller 4 can transmit the execution signal to unlock or lock the tilt unit 1. If the duration exceeds this time and the tilt controller 4 still determines that the unlock switch 32 is malfunctioning, the tilt controller 4 will first stop the warning sound element 6 and transmit an unlock signal to the tilt unit 1 to automatically unlock the tilt unit 1. The aforementioned function can automatically unlock the vehicle when the locking function of the control switch 3 fails for a period of time and cannot be resolved, allowing the user to tow the vehicle to a repair shop or other location. In this first embodiment, the actuation time is 6 seconds, but it is not limited to this. It should be noted that when the locking switch 31 is determined to be faulty, the unlocking switch 32 can still be pressed to perform the unlocking function, and conversely, when the unlocking switch 32 is determined to be faulty, the locking function can still be performed.

[0068] In addition to detecting and monitoring faults such as short circuits or button jams in the control switch 3 after the vehicle is powered on, the tilt controller 4 can also control the locking and unlocking of the tilt function based on the vehicle's driving conditions. When the engine control unit 7 detects an engine speed of less than 900 rpm, it indicates that the vehicle is parked, towing, or undergoing maintenance. In this case, pressing the control switch 3 will unlock or lock the tilt unit 1. When the engine speed is between 900 rpm and 3000 rpm, the vehicle is typically in different driving states. When the engine speed is less than 2000 rpm and the wheel speed is less than 10 km / h, such as when driving slowly or preparing to park, pressing the control switch 3 will directly lock or unlock the tilt unit 1. When the engine speed is greater than 2200 rpm and the wheel speed is greater than 2 km / h, such as when the vehicle is about to accelerate from a green light, the tilt controller 4 will send an unlock signal to the tilt unit 1 to automatically release the restriction on the tilt unit 1, facilitating the vehicle's start-up. When the engine speed is greater than 3000 rpm, it means that the vehicle has reached a certain speed. At this time, the tilt controller 4 will also send the unlock signal to the tilt unit 1 to automatically unlock the tilt unit 1 and stop sending the lock execution signal. This ensures that the user can use the tilt function normally while driving and will not trigger the locking function due to accidental touch of the control switch 3, effectively improving driving safety.

[0069] See Figure 8 and Figure 9 This is a second embodiment of the vehicle with tiltable front wheels of the present invention. This second embodiment is largely the same as the first embodiment, except that the hydraulic pump 161 only drives the travel lock 15, and the transmission mechanism 16 also has an auxiliary motor 164 that drives the tilt lock 14. The tilt controller 4 also uses a current sensor to sense whether the current value of the auxiliary motor 164 exceeds a threshold to confirm whether the auxiliary motor 164 is stalled, thereby understanding the state of the auxiliary motor 164. The tilt lock 14 has a connector 141 connecting the two crossbars 11, and a clamp 142 that can be controlled by the auxiliary motor 164 to clamp the connector 141. The bottom end of the connector 141 is pivotally mounted on the lower crossbar 11 and can slide vertically and pivotally connected to the upper crossbar 11. Thus, when the catcher 142 is not clamping the connector 141, the connector 141 can swing left and right with its bottom end as a fulcrum, allowing the two side rods 12 to maintain their tilting function. However, when the auxiliary motor 164 drives the reduction gear (not shown) to clamp the top end of the connector 141 with the catcher 142, the degree of freedom of the connector 141 is significantly restricted, preventing the two side rods 12 from tilting and achieving a locking function. This second embodiment provides another mechanism configuration applicable to the vehicle, improving design flexibility and versatility.

[0070] In summary, the present invention can detect whether the control switch 3 is short-circuited or stuck, and stop the unlocking and locking functions to avoid accidentally triggering the locking or unlocking functions when the vehicle is powered on, thus ensuring the safety and convenience of the user. It can also trigger the automatic unlocking function as needed to deal with special situations, so it can indeed achieve the purpose of the present invention.

[0071] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the patent of the present invention.
