Description

TECHNICAL FIELD

[0001] The application relates to a two-wheeled electric vehicle seat cushion heating system and belongs to the technical field of electric vehicle seat cushion heating. BACKGROUND

[0002] In the actual use process of a two-wheeled electric vehicle, the use experience of a seat cushion is greatly affected by seasonal factors. When the temperature is low in winter, most two-wheeled electric vehicle seat cushions are not equipped with a heating function. When a consumer rides, the buttocks directly contact the cold seat cushion, which not only produces a strong sense of discomfort, but also may have an adverse effect on health after a long ride. Even if part of the seat cushions have a heating function, there are still a series of technical defects:

[0003] Temperature control is not accurate: the temperature cannot be flexibly and accurately adjusted according to the environmental temperature and the individualized needs of users, and there are often risks of burns due to excessively high temperatures or insufficient temperatures that cannot effectively resist the cold.

[0004] Low energy utilization efficiency: an effective energy recycling mechanism has not been built, and energy is seriously wasted during heating, which undoubtedly increases the burden on the vehicle battery and has a negative impact on the vehicle's range.

[0005] In the summer, when it rains frequently, many two-wheeled electric vehicles are parked outdoors, and the seat cushions are easily wetted by rain. A wet seat cushion not only gives people a sense of discomfort and cold when riding, affecting the comfort of riding, but also easily becomes a breeding ground for bacteria, producing a foul odor. The existing seat cushions generally lack a rapid drying function, and consumers often have to wait for the seat cushions to dry naturally, which takes a long time and greatly affects the convenience of using the seat cushions. Some consumers try to wipe the surface of the seat cushion with a towel, but this method cannot completely remove the moisture inside the seat cushion and cannot fundamentally solve the problem.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0032] The present application provides a seat cushion heating system for a two-wheeled electric vehicle. Through energy conversion of the motor, energy circulation of the energy circulation system and control of the control system, the energy is converted into heat energy of the heating wire, realizing the continuous heating function of the seat cushion. This design not only effectively solves the problem of consumer discomfort caused by cold seat cushion in winter, but also quickly dries the wet seat cushion in summer and rainy season. At the same time, the present application fully considers the accurate control of temperature and the safety performance in the use process, bringing a more high-quality, comfortable and safe riding experience to consumers. The following specific implementation schemes are described by way of non-limiting examples.

[0033] Reference Figures 1-3 , Figure 1 A schematic diagram of the module structure of the seat cushion heating system of the two-wheeled electric vehicle according to the embodiment of the present application is provided. Figure 2 A schematic diagram of the connection structure of the seat cushion heating system of the two-wheeled electric vehicle according to the embodiment of the present application is provided. Figure 3 Another angle of the connection structure of the seat cushion heating system of the two-wheeled electric vehicle according to the embodiment of the present application is provided. As shown in Figures 1-3 the present embodiment provides a seat cushion heating system for a two-wheeled electric vehicle, which comprises an energy circulation system, a heating wire and a control system.

[0034] The energy circulation system comprises an energy collection module, an energy distribution module, an energy storage module and a circulation pipeline; the energy collection module is used to collect energy from the motor of the vehicle when the motor is running, and the energy is transported to the energy storage module for storage through the energy distribution module; the circulation pipeline is used for transmission of energy between the energy collection module, the energy distribution module and the energy storage module, so as to reduce the loss of energy in the transmission process.

[0035] The heating wires are laid in the seat cushion to generate heat for heating or drying the seat cushion. Specifically, a seat cushion bottom plate is arranged in the seat cushion, and the heating wires are laid on the seat cushion bottom plate. The heating wires are connected with each other to form a uniform heating layer. The heating wires are made of flexible material and can closely fit the shape of the seat cushion, so that the heat can be uniformly distributed in each part of the seat cushion, avoiding local overheating or overcooling.

[0036] The control system comprises a controller, a temperature sensor, a power adjustment module and a human-computer interaction module; the controller is used to control each module of the seat cushion heating system of the two-wheeled electric vehicle; the temperature sensor is used to detect the ambient temperature and the seat cushion temperature; the power adjustment module is used to adjust the heating power of the heating wires; and the human-computer interaction module is used to interact with the user.

[0037] The overall working principle of the system is as follows: during the operation of the system, the energy collection module continuously collects energy and transmits it to the energy storage module for storage. The energy storage module comprises a super capacitor or other high-performance energy storage battery, which has the characteristics of fast charging and discharging, and can temporarily store the collected energy to ensure the stability of energy supply. When the seat cushion needs to be heated, the energy distribution module extracts energy from the energy storage module according to the demand signal fed back by the controller and delivers it to the controller and the power adjustment module. The controller sends a control instruction to the power adjustment module according to the ambient temperature and / or user instruction, so that the power adjustment module adjusts the heating power of the heating wires.

[0038] In addition, during the energy collection process of the energy collection module, the energy distribution module is used to store the energy collected by the energy collection module in the energy storage module according to the current power of the energy storage module, or deliver it to the battery or power module of the vehicle. For example, when the power of the energy storage module is too high, the energy distribution module will automatically adjust the energy distribution strategy to return the excess energy to the battery system of the electric vehicle or adopt other reasonable energy consumption methods (such as powering the vehicle lights) to ensure stable operation of the entire system.

[0039] In some embodiments, the energy collection module converts part of the excess energy generated by the motor into electrical energy to achieve energy collection. Specifically, in this embodiment, the energy collection module collects energy by using the principle of "excess energy recovery". For example, when the motor is not running at full load, such as when the electric vehicle is lightly loaded or traveling at a constant speed, the input power of the motor is greater than the actual driving power required, and the excess energy can be led out through the circuit. For another example, when the electric vehicle is decelerating or downhill, the wheels will rotate the motor, at this time, the motor (such as a brushless direct current motor BLDC or a permanent magnet synchronous motor PMSM) can work in a power generation mode to convert mechanical energy into electrical energy.

[0040] In this way, by collecting and storing the "excess" energy during the operation of the electric vehicle in the above manner, the consumption of the vehicle battery can be effectively reduced, and the operation of the heating system can be avoided to affect the endurance of the vehicle.

[0041] In some embodiments, the energy collection module can also include a thermoelectric power generation device for generating electrical energy using the temperature difference between the heated seat cushion and the external environment. Specifically, in practice, when the seat cushion is heated, part of the heat will be directly dissipated into the air, resulting in waste. In addition, after the user stops riding, the heat of the heated seat cushion will not be immediately consumed, but will be slowly released into the environment. Therefore, in this embodiment, a thermoelectric power generation device can be arranged inside the seat cushion, which can generate electricity using the temperature difference between the seat cushion and the environment. The generated electrical energy can be stored in the energy storage module to achieve the recycling of energy.

[0042] In addition, in the hardware composition of the control system: the controller is the core of a high-performance microprocessor, which is matched with high-precision temperature sensors, power regulation modules, and user interaction interfaces and other components. The high-precision temperature sensor uses advanced thermistor technology, and multiple sensors are arranged at appropriate positions according to the actual situation to accurately sense the real-time temperature of the seat cushion and the external environment, and the measurement accuracy can reach ±0.1℃. The power regulation module can use intelligent power semiconductor devices, which can quickly and accurately adjust the heating power according to the instructions of the microprocessor, and the adjustment range is 0-100%.

[0043] In addition, the human-computer interaction module includes a touch screen or a key control panel for user to set heating temperature and / or heating mode; wherein the heating mode includes a fast heating mode, a constant temperature mode and a drying mode. The microprocessor adjusts the control strategy according to the heating mode selected by the user to meet the diversified needs of the user. In the fast heating mode, the heating wire operates at the highest power so as to realize fast heating of the seat cushion. In the constant temperature mode, the controller dynamically adjusts the working parameters of the power adjustment module to maintain the seat cushion at the temperature set by the user. In the drying mode, the seat cushion is targeted to be dried quickly, and when the moisture on the seat cushion is detected to be dried (which can be detected by a humidity sensor), or the duration of the drying mode reaches the set time, the drying mode is automatically exited, the heating wire is powered off, and the heating is stopped.

[0044] For the drying mode, when the seat cushion is wet due to the rainy season in summer, the user can start the drying function through the interactive interface. At this time, the controller controls the heating wire to heat at an appropriate power according to the preset drying program, so that the moisture in the seat cushion gradually evaporates. At the same time, the controller adjusts the heating power and heating time in real time according to the data fed back by the temperature sensor and the humidity sensor (if equipped), to ensure that the seat cushion can be quickly and completely dried, and to avoid damage to the seat cushion material due to excessive heating.

[0045] During the heating process, the high-precision temperature sensor monitors the temperature of the seat cushion in real time and feeds back the temperature data to the controller. The controller compares the actual temperature with the temperature value set by the user (or automatically set by the system according to the current heating mode), and according to the difference between the two, calculates the heating power that needs to be adjusted by using the PID control algorithm, and issues an instruction to the power adjustment module to adjust the heating power of the heating wire in real time, so as to ensure that the temperature of the seat cushion can be stabilized near the target temperature value.

[0046] The principle of the PID control algorithm is as follows:

[0047]

[0048] In the formula, u(t) is the control amount output by the controller; e(t) is the error signal, i.e. the difference between the target temperature value and the actual temperature value; K p is the proportional gain, which is used to amplify the error signal and speed up the response; K i is the integral gain, which is used to eliminate static error and adjust the control amount by accumulating historical error; K d is the differential gain, which is used to suppress system oscillation and adjust the control amount in advance according to the error change rate.

[0049] In addition, if the control system further comprises a humidity sensor for detecting the seat cushion humidity, in the heating mode, the controller is further configured to intelligently adjust the output power of the power adjustment module according to the seat cushion temperature, the seat cushion humidity and the target temperature of the seat cushion by using a PID algorithm. By combining the seat cushion humidity data, the adjustment of the heating power can be better realized. For example, when the seat cushion humidity is large, the heating power is appropriately increased so as to improve the heating efficiency and make the seat cushion reach the target temperature faster.

[0050] In addition, in some embodiments, the control system further comprises a safety protection circuit, which comprises an overcurrent protection circuit, an overvoltage protection circuit, an undervoltage protection circuit, a short-circuit protection circuit and an overheating protection circuit. The safety protection circuit integrates various protection functions such as overcurrent protection, overvoltage protection, undervoltage protection, short-circuit protection and overheating protection, and uses high-speed response electronic components to cut off the circuit in an instant when an abnormal situation occurs, thereby ensuring the safety of the system.

[0051] During the operation of the heating system, the controller continuously monitors the state of the safety protection circuit, and once an abnormal situation such as overcurrent, overvoltage, undervoltage, short circuit or overheating is detected, an instruction is immediately sent to cut off the power supply through the safety protection circuit to prevent safety accidents and comprehensively protect the personal and property safety of the user.

[0052] In addition, in some embodiments, the heating wire is made of a flexible material, and the outside of the heating wire is wrapped with a flexible material that is insulated and resistant to high temperature. Preferably, the insulation resistance is greater than 1000MΩ, which can effectively prevent the occurrence of electric leakage and ensure the personal safety of the user during use. At the same time, the high-temperature resistance needs to reach a high temperature of 200℃ without deformation or damage, which further enhances the safety and reliability of the heating wire.

[0053] The two-wheeled electric vehicle seat cushion heating system and the control method provided by the present application have the following advantages and positive effects compared with the prior art:

[0054] Through the heating wire, the seat cushion can be continuously and stably heated to provide a warm and comfortable riding experience for consumers, effectively solving the problem that the cold seat cushion brings to consumers; and in the summer and rainy season, a rapid drying function can be provided to quickly remove the moisture on the seat cushion, avoid the consumer from contacting the cold and damp seat cushion, and reduce the problem of bacterial growth and odor generation, thereby greatly improving the use convenience and comfort of the seat cushion under different seasons and weather conditions.

[0055] In addition, consumers can easily set the temperature and heating mode of the seat cushion through the user interaction interface according to their actual needs, and the controller can realize accurate adjustment of the temperature of the seat cushion, thereby avoiding the risk of scalding caused by too high temperature and the problem that the cold cannot be effectively driven away due to too low temperature, and meeting the individualized needs of different users for the temperature of the seat cushion under different environments.

[0056] In addition, through the unique motor energy extraction method and the energy recycling mechanism of the energy recycling system, efficient recovery and reuse of energy are realized. The energy recycling system can collect, store and redistribute part of the energy during the operation of the motor and the remaining energy during the heating process, greatly reducing the energy loss during transmission and use, reducing the additional burden on the vehicle battery, ensuring the normal operation of the seat cushion heating and drying functions, and not significantly affecting the vehicle's range, providing a more efficient and sustainable solution for the energy utilization of two-wheeled electric vehicles.

[0057] In addition, the safety performance is excellent: the outer layer of the heating wire is wrapped with high insulation and high temperature resistant material, and the controller integrates multiple safety protection mechanisms, which fundamentally eliminates the safety hazards such as leakage, overheating and short circuit. Whether in normal use or in extreme conditions, it can provide reliable safety protection for consumers, allowing consumers to enjoy the seat cushion heating and drying functions without worrying about safety issues, and effectively protecting the safety of consumers' persons and property.
