Description

Technical Field

[0001] This invention relates to the field of electric motorcycle technology, and more specifically, to a shock-resistant intelligent electric motorcycle. Background Technology

[0002] Electric motorcycles are a type of electric vehicle that uses a battery to power an electric motor. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. Other components of an electric motorcycle are basically the same as those of an internal combustion engine motorcycle.

[0003] An electric motorcycle consists of: an electric drive and control system, a mechanical system including drive transmission, and a work device to perform the designated task. The electric drive and control system is the core of an electric motorcycle and the biggest difference between it and a vehicle powered by an internal combustion engine.

[0004] Currently, intelligent electric motorcycles on the market typically include a front and rear wheel; an electric motor that generates power to drive the rear wheel; a frame with a head tube supporting the steering shaft and a main frame extending rearward from the head tube; a battery that supplies power to the electric motor; and a battery casing that houses the battery. Traditional intelligent electric motorcycles have a lower level of intelligence, for example, in the form of anti-theft systems; moreover, traditional electric motorcycles have poor shock resistance, and even with multiple springs, damage to the frame can still occur, reducing their lifespan. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a shock-resistant intelligent electric motorcycle with good shock resistance, high level of intelligence, and strong practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shock-resistant intelligent electric motorcycle, including a front wheel and a rear wheel; an electric motor that generates driving power for driving the rear wheel; a frame having a head tube supporting a steering shaft and a main frame extending rearward from the head tube; a battery for supplying power to the electric motor; a battery housing for housing the battery; and a module with an IoT mobile terminal, intelligent anti-theft, intelligent lighting, a mid-drive system, front and rear direct tire pressure alarms, GPS / ICS, ABS anti-lock braking system, and TCS traction control. The intelligent anti-theft PKE includes a low-frequency antenna, a PKE controller, a smart key, and a tire pressure sensor. The PKE controller and the tire pressure sensor are paired and connected via high-frequency signals. When abnormal tire pressure or excessive tire temperature occurs, the tire pressure sensor sends a signal to the PKE controller. The PKE controller converts the signal into a digital signal and transmits it to the IoT via CANBUS. The smart key is connected to the PKE controller via low-frequency and high-frequency signals. The smart key has the function of locking the PKE controller, and the button on the smart key can control whether the PKE controller enters sleep mode.

[0007] The present invention is further configured such that the PKE controller has a dual-battery switching function. When the vehicle ignition switch is in the OFF position, the vehicle's electrical system is powered by the on-board small battery. When the vehicle is in the ON position, the PKE will automatically switch to power battery power.

[0008] The present invention is further configured such that: the mid-drive system includes a PMSM motor, an MCU, a transmission mechanism, an ABS braking system, etc.; when the vehicle is driving on a low-friction surface, the rear wheels are prone to slippage. When slippage occurs, the ABS sensor will send a command to the MCU. The MCU controls the power and torque output of the drive motor according to the slippage signal provided by the ABS, thereby reducing the overall vehicle traction output and effectively preventing slippage.

[0009] The present invention is further configured such that: the vehicle communicates via CAN BUS, and there is a communication protocol between each module, which is used to control whether the vehicle starts working; the Internet of Things module integrates VCU and battery management system; VCU is used to control the vehicle's instrument panel, MCU, PKE, and battery, and the battery supplies power to the MCU through the Internet of Things, and the MCU drives the motor.

[0010] The present invention is further configured such that: a shock-absorbing mechanism is provided on the vehicle frame between the motor and the vehicle frame, the shock-absorbing mechanism including a vibration plate on the vehicle frame, a mounting plate below the motor, a pressure-resistant plate on the vehicle frame and perpendicular to the vehicle frame, a plurality of cylinder structures for transferring force on the mounting plate, a first transmission structure between the vibration plate and the cylinders, and a second transmission structure between the pressure-resistant plate and the cylinders.

[0011] The present invention is further configured such that: the cylinder structure includes a longitudinally arranged force-bearing cylinder and a transversely arranged conversion cylinder disposed in a straight tube, and an internal buffer structure disposed between the force-bearing cylinder and the conversion cylinder.

[0012] The present invention is further configured such that: the first transmission structure includes a push rod connected to the vibrating plate, a first piston connected to the push rod and placed inside the force-receiving cylinder, and a first buffer spring disposed between the force-receiving cylinder and the push rod and sleeved outside the rod body of the first piston; the second transmission structure includes a top rod connected to the pressure-resistant plate, a second piston connected to the top rod and placed inside the conversion cylinder, and a second buffer spring disposed between the inner wall of the conversion cylinder and the second piston and sleeved outside the rod body of the second piston.

[0013] The present invention is further configured such that: the internal buffer structure includes a buffer cylinder disposed between the force-bearing cylinder and the conversion cylinder, a rotating shaft disposed inside the buffer cylinder, and a buffer wheel sleeved outside the rotating shaft and rotatably connected to the rotating shaft.

[0014] The present invention is further configured such that the number of cylinder structures is 4, and the cylinders of two adjacent cylinder structures are arranged facing away from each other.

[0015] By adopting the above technical solution, the following benefits are achieved: 1. The structural design improves the intelligence level of the electric motorcycle. When abnormal tire pressure or excessive tire temperature occurs, the tire pressure sends a signal to the PKE controller. The PKE controller converts the signal into a digital signal and transmits it to the IoT via CANBUS. The smart key is connected to the PKE controller via low-frequency and high-frequency signals. The smart key has the function of locking the PKE controller. The button on the smart key can control whether the PKE controller enters sleep mode. The PKE controller has a dual-battery switching function. When the vehicle's ignition switch is in the OFF position, the vehicle's electrical system is powered by the onboard small battery. When the vehicle is in the ON position, the PKE will automatically switch to power battery power. The mid-drive system includes a PMSM motor, MCU, transmission mechanism, ABS braking system, etc. When the vehicle is traveling on a low-friction surface, the rear wheel is prone to slippage. When slippage occurs, the ABS sensor will send a command to the MCU. The MCU controls the power and torque output of the drive motor according to the slippage signal provided by the ABS, thereby reducing the overall vehicle traction output and effectively preventing slippage.

[0016] 2. By communicating the entire vehicle via CAN BUS, there is a communication protocol between each module, which is used to control whether the vehicle starts working; the IoT module integrates VCU and battery management system; VCU is used to control the vehicle's instrument panel, MCU, PKE, and battery. The battery supplies power to the MCU through the IoT, and the MCU drives the motor, realizing the vehicle's intelligence level, strong practicality, and simple structure.

[0017] 3. By setting up a shock absorption mechanism, the impact of vibration on the vehicle body in the longitudinal direction is reduced. This is achieved through a vibration plate set on the vehicle body frame, a mounting plate set below the motor, a pressure-resistant plate set on the vehicle body frame and perpendicular to the vehicle body frame, several cylinder structures set on the mounting plate for transferring the force, a first transmission structure set between the vibration plate and the cylinders, and a second transmission structure set between the pressure-resistant plate and the cylinders. Under the action of the cylinder structures, the force is transferred, changing the longitudinal force into a lateral force, thereby reducing the impact on the vehicle body frame.

[0018] 4. Furthermore, through multiple sets of relatively arranged cylinder structures, combined with the first and second transmission mechanisms, the uniformity of force distribution on the vehicle body frame is achieved, resulting in good structural stability. The structure is simple and highly practical. Attached Figure Description

[0023] Reference Figures 1 to 3 The following is a further description of an embodiment of the shock-resistant intelligent electric motorcycle of the present invention.

[0024] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0026] A shock-resistant intelligent electric motorcycle includes a front wheel 1 and a rear wheel 2; an electric motor 3 that generates driving power for the rear wheel 2; a frame 4 having a head tube supporting a steering shaft and a main frame extending rearward from the head tube; a battery for supplying power to the electric motor 3; a battery housing for housing the battery; and a module integrating an IoT mobile terminal, intelligent anti-theft, intelligent lighting, a mid-drive system, front and rear direct tire pressure alarms, GPS / ICS, ABS anti-lock braking system, and TCS traction control. The intelligent anti-theft PKE includes a low-frequency antenna, a PKE controller, a smart key, and a tire pressure sensor. The PKE controller and the tire pressure sensor are paired and connected via a high-frequency signal. When abnormal tire pressure or excessive tire temperature occurs, the tire pressure sensor sends a signal to the PKE controller. The PKE controller converts signals into digital signals and transmits them to the IoT via CANBUS. The smart key is connected to the PKE controller via low-frequency and high-frequency signals. The smart key has the function of locking the PKE controller, and the button on the smart key can control whether the PKE controller enters sleep mode. This structural design improves the intelligence level of the electric motorcycle. When abnormal tire pressure or excessive tire temperature occurs, the tire pressure sends a signal to the PKE controller, which converts the signal into a digital signal and transmits it to the IoT via CANBUS. The smart key is connected to the PKE controller via low-frequency and high-frequency signals. The smart key has the function of locking the PKE controller, and the button on the smart key can control whether the PKE controller enters sleep mode.

[0027] The invention is further configured such that the PKE controller has a dual-battery switching function. When the vehicle's ignition switch is in the OFF position, the vehicle's electrical system is powered by the onboard small battery. When the vehicle is in the ON position, the PKE will automatically switch to power battery power. The mid-drive system includes a PMSM motor, MCU, transmission mechanism, ABS braking system, etc. When the vehicle is traveling on a low-friction surface, the rear wheel 2 is prone to slippage. When slippage occurs, the ABS sensor will send a command to the MCU. Based on the slippage signal provided by the ABS, the MCU controls the power and torque output of the drive motor, thereby reducing the vehicle's traction output and effectively preventing slippage. When a situation arises, the PKE controller has a dual-battery switching function. When the vehicle's ignition switch is in the OFF position, the vehicle's electrical system is powered by the onboard small battery. When the vehicle is in the ON position, the PKE will automatically switch to power battery power. The mid-drive system includes a PMSM motor, MCU, transmission mechanism, ABS braking system, etc. When the vehicle is driving on a low-friction surface, the rear wheels are prone to slippage. When slippage occurs, the ABS sensor will send a command to the MCU. The MCU, based on the slippage signal provided by the ABS, controls the power and torque output of the drive motor, thereby reducing the vehicle's traction output and effectively preventing slippage.

[0028] This invention is further configured such that the entire vehicle communicates via CAN BUS, and there is a communication protocol between each module. This communication protocol is used to control whether the vehicle starts and operates. The IoT module integrates a VCU and a battery management system. The VCU controls the vehicle's instruments, MCU, PKE, and battery. The battery supplies power to the MCU via the IoT, and the MCU drives the motor. By enabling the entire vehicle to communicate via CAN BUS, with communication protocols between each module used to control whether the vehicle starts and operates, and by integrating a VCU and a battery management system into the IoT module, the invention achieves a high level of vehicle intelligence, is highly practical, and has a simple structure.

[0029] The invention is further configured such that a shock-absorbing mechanism is provided on the vehicle frame 4 between the motor and the vehicle body. This shock-absorbing mechanism includes a vibration plate 50 on the vehicle body frame, a mounting plate 51 below the motor, a pressure-resistant plate 52 on the vehicle body frame and perpendicular to it, several cylinder structures 6 on the mounting plate 51 for transferring force, a first transmission structure between the vibration plate 50 and the cylinders, and a second transmission structure between the pressure-resistant plate 52 and the cylinders. Through this shock-absorbing mechanism, the impact of vibration on the vehicle body is reduced. The longitudinal influence of the vehicle body is mitigated by a vibration plate 50 mounted on the vehicle frame, a mounting plate 51 located below the motor, a pressure-resistant plate 52 mounted on the vehicle frame and perpendicular to it, several cylinder structures 6 mounted on the mounting plate 51 for transferring forces, a first transmission structure between the vibration plate 50 and the cylinders, and a second transmission structure between the pressure-resistant plate 52 and the cylinders. These mechanisms transfer the forces under the action of the cylinder structures 6, changing the longitudinal force into a lateral force, thereby reducing the impact on the vehicle frame.

[0030] The present invention is further configured such that the cylinder structure 6 includes a longitudinally arranged force-receiving cylinder 61 and a transversely arranged conversion cylinder 62 in a straight tube. With the above-mentioned structural configuration, the force direction is converted by the cooperation between the force-receiving cylinder 61 and the conversion cylinder 62. The inner buffer structure 7 is set between the force-receiving cylinder 61 and the conversion cylinder 62. The inner buffer structure 7 buffers and reduces the pressure of the force, thereby increasing the force-receiving effect, increasing stability, and simplifying the structure.

[0031] The present invention is further configured such that the first transmission structure includes a push rod 601 connected to the vibrating plate 50, a first piston 602 connected to the push rod 601 and placed inside the force-receiving cylinder 61, and a first buffer spring 603 disposed between the force-receiving cylinder 61 and the push rod 601 and sleeved on the outside of the rod of the first piston 602; the second transmission structure includes a top rod 604 connected to the pressure-resistant plate 52, a second piston 605 connected to the top rod 604 and placed inside the conversion cylinder 62, and a second buffer spring 606 disposed between the inner wall of the conversion cylinder 62 and the second piston 605 and sleeved on the outside of the rod of the second piston 605. With the above-described structural configuration, the first and second transmission structures are identical, both employing pistons and buffer springs in cooperation, resulting in a simple structure, strong practicality, good buffering effect, and strong stability.

[0032] The present invention is further configured such that the inner buffer structure 7 includes a buffer cylinder 70 disposed between the force-bearing cylinder 61 and the conversion cylinder 62, a rotating shaft 71 disposed within the buffer cylinder 70, and a buffer wheel 72 sleeved on the outside of the rotating shaft 71 and rotatably connected to the rotating shaft 71. With the above-mentioned structure, when the force-bearing cylinder 61 is subjected to force, the oil pressure impacts the buffer wheel 72. The present invention converts the directional force into a directional force through the buffer cylinder, which not only reduces the impact on the vehicle body, but also reduces the impact on the buffer cylinder itself through the structure of the buffer wheel 72 in conjunction with the rotating shaft 71, thereby increasing the service life.

[0033] The present invention is further configured such that the number of cylinder structures 6 is 4, and the cylinders of two adjacent cylinder structures 6 are arranged facing away from each other. Through multiple sets of relatively arranged cylinder structures 6, combined with the first and second transmission mechanisms, the uniformity of force on the vehicle body frame is achieved, and good structural stability is achieved. The structure is simple and highly practical.
