Description

Technical Field

The present invention is particularly suitable for electric vehicles traveling in soft terrain environments such as beaches and deserts, and can also be applied to other special terrain vehicles that require intelligent control and environmental adaptation. Background Art

However, this emerging means of transportation also faces some challenges in actual use, especially in terms of energy efficiency and driving experience.

[0003] On regular roads, improper driving habits such as frequent sudden acceleration and braking have already put a certain burden on the vehicle system. But when the environment changes to the special terrain of the beach, the problem is more prominent. The soft geology of the beach greatly increases the driving resistance. At this time, sudden acceleration not only requires the power system to output more power, but also increases battery consumption. At the same time, due to the fluidity of sand, sudden braking will result in longer braking distance and higher energy consumption.

[0031] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0032] Below are all the attached Figure 1-8 Embodiments of the present invention are described in detail.

[0033] Example 1 An intelligent electric beach vehicle according to an embodiment of the present invention comprises a beach vehicle body 1, a terrain identification device 2 and a handle-controlled isolation device 3, wherein the terrain identification device 2 is arranged on the body of the beach vehicle body 1; the handle-controlled isolation device 3 is arranged inside the beach vehicle body 1; the terrain identification device 2 and the handle-controlled isolation device 3 are respectively connected to an electric driving force device 4 arranged on the chassis of the beach vehicle body 1.

[0034] Specifically, the terrain recognition device 2 provided in the device can quickly and effectively recognize the beach terrain. When the terrain recognition device 2 recognizes that the vehicle is on the beach, the terrain recognition device 2 sends data information to the controller 43 in the electric driving force device 4, and the controller 43 controls the handle control isolation device 3 to operate. The handle control isolation device 3 operates to disconnect the direct connection between the speed control handle 46 and the controller 43, so that the driver cannot control the vehicle speed by turning the speed control handle 46. Through the preset speed parameters, the controller 43 can accurately control the motor 44 to operate at a constant and optimized speed, thereby driving the vehicle smoothly and efficiently according to the set speed. This setting effectively curbs the driver's frequent sudden acceleration operations on the beach due to bad driving habits, fundamentally reduces the unnecessary load of the power system and the rapid consumption of battery power, achieves a significant improvement in energy efficiency, and has a good use effect. When the terrain recognition device 2 recognizes that the vehicle is in a terrain other than the beach, the terrain recognition device 2 sends data information to the controller 43 in the electric drive power device 4, and the controller 43 controls the handle control isolation device 3 to operate again. The handle control isolation device 3 operates again to connect the speed control handle 46 with the controller 43, so that the driver can control the vehicle speed by turning the speed control handle 46.

[0035] In one embodiment of the present invention, Figure 3 As shown, the electric driving force device 4 includes a main battery 41, an inverter 42, a controller 43, a motor 44, a fixed speed ratio reducer 45 and a speed regulating handle 46, wherein the main battery 41, the inverter 42, the controller 43, the motor 44 and the fixed speed ratio reducer 45 are sequentially arranged on the chassis of the beach vehicle body 1, and the speed regulating handle 46 is arranged on the handlebar of the beach vehicle body 1; the main battery 41 is electrically connected to the controller 43, the output ends of the terrain recognition device 2 and the speed regulating handle 46 are respectively connected to the input end of the controller 43, the output end of the controller 43 is respectively connected to the handle control isolation device 3 and the input end of the inverter 42, the output end of the inverter 42 is connected to the input end of the motor 44, the output end of the motor 44 is connected to the input end of the fixed speed ratio reducer 45, and the output end of the fixed speed ratio reducer 45 is connected to the input end of the differential on the rear axle of the beach vehicle body 1.

[0036] It should be noted that the main battery 41, inverter 42, controller 43, motor 44, fixed speed ratio reducer 45 and speed regulating handle 46 described in this embodiment are all existing technologies, so they will not be described in detail here.

[0037] It should also be noted that the controller 43 described in this embodiment stores preset rotation speed parameters internally.

[0038] Specifically, the controller 43 controls the output power of the inverter 42 according to the rotation angle of the speed control handle 46. The increase in the output power of the inverter 42 usually means that the electrical energy that can be provided to the motor 44 increases. Within the range allowed by the design of the motor 44, this causes the speed of the motor 44 to increase because more electrical energy is converted into mechanical energy. At the same time, the load capacity of the motor 44 may also be improved accordingly, that is, the motor 44 can drive heavier loads or run at higher speeds. As the speed of the motor 44 increases, the vehicle speed also increases accordingly.

[0039] In one embodiment of the present invention, Figure 4 As shown, the terrain recognition device 2 includes an environment information acquisition module 21, a vehicle body posture information acquisition module 22, a wheel information acquisition module 23 and an information processing module 24, wherein the environment information acquisition module 21 is arranged on the body of the beach vehicle body 1; the vehicle body posture information acquisition module 22 is arranged at the bottom of the beach vehicle body 1; the wheel information acquisition module 23 is arranged on the wheels of the beach vehicle body 1; the information processing module 24 is arranged inside the beach vehicle body 1; the output end of the environment information acquisition module 21, the output end of the vehicle body posture information acquisition module 22 and the output end of the wheel information acquisition module 23 are respectively connected to the input end of the information processing module 24, and the output end of the information processing module 24 is connected to the input end of the controller 43.

[0040] It should be noted that the terrain recognition device 2 described in this embodiment is used to recognize the terrain at the location of the vehicle, so as to determine whether it is on the beach.

[0041] Specifically, the structure and connection relationship of the terrain recognition device 2 are further explained.

A wheel information acquisition module 23 is set to collect wheel information to determine whether the vehicle is on the beach. The above collected information is uniformly transmitted to the information processing module 24 for comparison and judgment, and a conclusion is drawn. When the conclusion is that the vehicle is on the beach, the information processing module 24 transmits the data information to the controller 43, and the controller 43 controls the operation of the handle control isolation device 3.

The input end is connected to the output end of the controller 43; the vehicle body posture information acquisition module 22 includes a box body 221, a three-axis accelerometer 222, a three-axis gyroscope 223 and a three-axis electronic compass 224, wherein the box body 221 is fixedly connected to the bottom of the beach car body 1, the three-axis accelerometer 222, the three-axis gyroscope 223 and the three-axis electronic compass 224 are fixedly connected to the inner wall of the box body 221 in sequence, and the output ends of the three-axis accelerometer 222, the three-axis gyroscope 223 and the three-axis electronic compass 224 are respectively connected to the input end of the information processing module 24; the wheel information acquisition module 23 includes a temperature sensor 231, an air pressure sensor 232, a deformation sensor 233 and an ultra The ultrasonic sensor 234, wherein the temperature sensor 231, the air pressure sensor 232 and the deformation sensor 233 are respectively fixedly connected to the wheels of the beach vehicle body 1, the temperature sensor 231 is used to detect the tire temperature, the air pressure sensor 232 is used to detect the tire pressure, the deformation sensor 233 is used to detect the tire deformation, and the ultrasonic sensor 234 is used to detect the height of the tire from the ground; the output ends of the temperature sensor 231, the air pressure sensor 232, the deformation sensor 233 and the ultrasonic sensor 234 are respectively connected to the input end of the information processing module 24; the information processing module 24 includes a housing 241, a data processor 242 and a storage unit 243, which In the figure, the shell 241 is fixedly connected to the inner wall of the beach car body 1, the data processor 242 and the storage unit 243 are fixedly connected to the inner wall of the shell 241 in sequence, the data processor 242 is connected to the storage unit 243 through a control bus to realize data reading and writing, the input end of the data processor 242 is respectively connected to the output ends of multiple groups of vehicle-mounted cameras 211, light sensitive sensor 212, three-axis accelerometer 222, three-axis gyroscope 223, three-axis electronic compass 224, temperature sensor 231, air pressure sensor 232, deformation sensor 233 and ultrasonic sensor 234, and the output end of the data processor 242 is connected to the input end of the controller 43.

[0043] It should be noted that the vehicle-mounted camera 211, photosensor 212, lighting 213, three-axis accelerometer 222, three-axis gyroscope 223, three-axis electronic compass 224, temperature sensor 231, air pressure sensor 232, deformation sensor 233, ultrasonic sensor 234, data processor 242 and storage unit 243 described in this embodiment are all existing technologies and will not be described in detail here.

[0044] It should also be noted that the storage unit 243 internally stores data for comparison with the collected data.

[0045] Specifically, the structures and connection relationships of the environment information acquisition module 21, the vehicle body posture information acquisition module 22, the wheel information acquisition module 23 and the information processing module 24 are further explained. The on-board camera 211 takes pictures of the surrounding environment of the current position of the vehicle, and compares the taken pictures with the beach pictures in the storage unit 243. When the comparison results are consistent, it is determined that the vehicle is currently on the beach.

The lighting 213 provides a lighting environment for the on-board camera 211 at night. The three-axis accelerometer 222 is mainly used to measure the acceleration of the vehicle on three axes (X, Y, and Z axes), including linear acceleration and gravity acceleration. By measuring the change in gravity acceleration, the tilt angle of the vehicle can be calculated to understand the posture of the vehicle body. The three-axis gyroscope 223 can measure the rotational angular velocity of the device around each axis and is very sensitive to changes in the posture of the vehicle body. The three-axis electronic compass 224 determines the direction of the device by measuring the earth's magnetic field. It can provide accurate information about the vehicle's orientation, which helps to calibrate and compensate for the errors of other sensors and has a good effect. The temperature sensor 231 is used to detect the tire temperature. When driving on the beach, the friction will be greater, resulting in a higher temperature on the tire surface. The air pressure sensor 232 is used to detect the tire pressure. When the vehicle is driving on different terrains, the tire pressure sensor will capture subtle changes in tire pressure. By analyzing these tire pressure data, the type of terrain the vehicle is currently in can be preliminarily determined. The deformation sensor 233 is used to detect tire deformation. The type of terrain the vehicle is currently in can be determined by analyzing the tire deformation data. The ultrasonic sensor 234 is used to detect the height of the tire from the ground. The type of terrain the vehicle is currently in can be determined by analyzing the height data from the ground.

[0046] In one embodiment of the present invention, Figure 5As shown, the handle-controlled isolation device 3 includes an electromagnetic switching mechanism 30, an environmental adaptation adjustment mechanism 40, a fence, a safety warning mechanism 50 and a remote control mechanism 60, wherein the electromagnetic switching mechanism 30 and the remote control mechanism 60 are respectively arranged inside the beach vehicle body 1, the environmental adaptation adjustment mechanism 40 and the fence, the safety warning mechanism 50 are respectively arranged at the bottom of the beach vehicle body 1, and the electromagnetic switching mechanism 30, the environmental adaptation adjustment mechanism 40, the fence, the safety warning mechanism 50 and the remote control mechanism 60 are respectively connected to the controller 43 through a control bus.

[0047] Specifically, the structure and connection relationship of the handle-controlled isolation device 3 are further explained, wherein the electromagnetic switching mechanism 30 in the handle-controlled isolation device 3 can cut off the direct connection between the speed regulating handle 46 and the controller 43, effectively preventing the driver from manually controlling the handle 46 and causing sudden acceleration, thereby reducing power consumption and improving energy efficiency. The environmental adaptation adjustment mechanism 40 in the handle-controlled isolation device 3 can detect the humidity and compactness of the sand under the vehicle, and the controller 43 can automatically adjust the output power of the motor 44 according to environmental parameters such as the humidity and compactness of the beach, so as to further optimize power consumption and energy efficiency. The fence system in the fence and safety warning mechanism 50 can detect whether the vehicle is in the beach environment and whether it is in a specific dangerous area on the beach when the vehicle enters the set beach geographical fence area. The difference between the terrain recognition device 2 detecting the beach environment is that the fence system 3 in the handle-controlled isolation device can only play a detection role in the set beach geographical fence area. The fence in the handle-controlled isolation device 3 and the safety warning system in the safety warning mechanism 50 can be used in conjunction with the fence system, the environmental adaptation adjustment mechanism 40 and the vehicle body posture information collection module 22. When the vehicle drives to the dangerous area on the beach, the control The controller 43 combines the geographical location of the fence system, the beach information detected by the environmental adaptation adjustment mechanism 40 and the body posture information detected by the body posture information collection module 22 to determine whether the vehicle is in a dangerous area on the beach. When in a dangerous area, an alarm message will be issued through the sound and light alarm 502, and the output power of the motor 44 will be adjusted at the same time to control the driving speed and give the driver enough time to change direction. The electromagnet circuit detection unit 601 in the remote control mechanism 60 in the handle control isolation device 3 can detect whether the power circuit of the electromagnet 302 has been damaged by human beings. If the power circuit is damaged, it will be impossible to disconnect. In order to establish a direct connection between the speed regulating handle 46 and the controller 43, an electromagnet circuit detection unit 601 is provided to detect the power-on status of the power-on circuit of the electromagnet 302 in real time to determine whether the power-on circuit is damaged. The battery circuit disconnection unit 602 in the remote control mechanism 60 in the handle-controlled isolation device 3 is used to disconnect the power-on circuit between the controller 43 and the inverter 42 after the power-on circuit of the electromagnet 302 is damaged, so that the motor 44 is powered off and stops running. The above status information can be sent to an external host computer through the wireless communication module 503, so that the staff can know it in time and carry out maintenance on it, which has a good use effect.

The humidity sensor 401 is used to detect the humidity of the sand below the beach vehicle body 1 during the driving process, and the compaction sensor 402 is used to detect the compaction of the sand in front of the vehicle during the driving process of the beach vehicle body 1. The output end of the humidity sensor 401 and the output end of the compaction sensor 402 are respectively connected to the input end of the controller 43; The fence and safety warning mechanism 50 includes a GPS locator 501, an audible and visual alarm 502 and a wireless communication module 503, wherein the GPS locator 501 is fixedly connected to the bottom of the beach vehicle body 1, the audible and visual alarm 502 is fixedly connected to the handlebar of the beach vehicle body 1, the wireless communication module 503 is arranged inside the controller 43, the output end of the GPS locator 501 is connected to the input end of the controller 43, the input end of the audible and visual alarm 502 is connected to the output end of the controller 43, and the controller 43 can perform data transmission and command reception with an external host computer through the wireless communication module 503; The remote control mechanism 60 includes an electromagnet circuit detection unit 601 and a battery circuit disconnection unit 602, wherein the electromagnet circuit detection unit 601 is installed on the power-on circuit of the electromagnet 302, and is used to detect in real time whether the power-on circuit of the electromagnet 302 is powered, and the battery circuit disconnection unit 602 is installed on the power-on circuit between the controller 43 and the inverter 42, and is used to change the power-on state of the group of power-on circuits; The output end of the electromagnet line detection unit 601 is connected to the input end of the controller 43 , and the output end of the controller 43 is connected to the input end of the battery line disconnection unit 602 .

[0049] It should be noted that the connection base 307 described in this embodiment is provided with an arc-shaped portion that matches the outer dimensions of the conductive head 305 , and the conductive head 305 is slidably connected to the surface of the arc-shaped portion.

[0050] It should also be noted that the electromagnet 302, humidity sensor 401, compaction sensor 402, GPS locator 501, sound and light alarm 502 and wireless communication module 503 are all existing technologies, so they are not described in detail here. Among them, the electromagnet circuit detection unit 601 is a resistive sensor, which is connected in parallel to the power-on circuit of the electromagnet 302 to detect whether the group of power-on circuits is disconnected. When the circuit is disconnected, the resistance value will change significantly. The battery circuit cut-off unit 602 is an electromagnetic control switch. When the electromagnetic control switch is opened (closed), the circuit between the controller 43 and the inverter 42 is connected, and the motor 44 is powered. When the electromagnetic control switch is closed (opened), the circuit between the controller 43 and the inverter 42 is disconnected, and the motor 44 is powered off. The resistive sensor and the electromagnetic control switch are all existing technologies, so they are not described in detail here.

[0051] Specifically, the electromagnetic switching mechanism 30 is used to cut off the line between the speed control handle 46 and the controller 43, making it temporarily ineffective. When the vehicle travels to the beach terrain, the controller 43 controls the electromagnet 302 to be energized and run. The electromagnet 302 is energized to generate magnetic force. Under the action of the magnetic force, the drive rod 303 moves to the side of the electromagnet 302 and stretches the spring 304. When the drive rod 303 and the electromagnet 302 are magnetically fixed, the conductive head 305 is separated from the conductive seat 308. When the conductive seat 308 is separated from the conductive head 305, the wires connected by the two sets of connecting seats 307 are disconnected to achieve power failure. After the wires are disconnected, the speed control handle 46 is temporarily inoperable. When the vehicle leaves the beach, the controller 43 controls the electromagnet 302 to cut off the power. Under the elastic force of the spring 304, the driving rod 303 is reset and drives the conductive seat 308 to contact the conductive head 305. When the conductive seat 308 is in contact with the conductive head 305, the wires connected by the two sets of connecting seats 307 immediately establish a current path to realize power-on. After the wires are powered on, the speed regulating handle 46 is reconnected to the controller 43, which is convenient for the driver to control and has a good use effect.

[0052] The humidity sensor 401 and the compaction sensor 402 are used to detect the humidity and compaction of the sand under the vehicle. The controller 43 can automatically adjust the output power of the motor 44 according to the humidity, compaction and other environmental parameters of the beach to further optimize power consumption and energy efficiency. When the beach humidity and compaction data are within the set range for a long time, the vehicle can travel smoothly and efficiently at the set speed.

[0053] The GPS locator 501 and the wireless communication module 503 cooperate to form a beach fence system. When the vehicle enters the set beach geo-fence area, the fence system can detect whether the vehicle is in the beach environment and whether it is in a specific dangerous area on the beach. When the vehicle is in the geo-fence formed by the beach fence system, it means that the vehicle is in the beach environment. The geo-fence includes a large fence area and a small fence area. The large fence area indicates entering the beach area, and the small fence area indicates entering the beach dangerous area. The difference between the terrain recognition device 2 detecting the beach environment is that the fence system in the handle-controlled isolation device 3 can only be in the set beach geo-fence area. The sound and light alarm 502 cooperates with the beach fence system, the environmental adaptation adjustment mechanism 40 and the body posture information collection module 22 to form a safety system. When the vehicle drives to a dangerous area on the beach, the controller 43 combines the geographical location of the beach fence system, the beach information detected by the environmental adaptation adjustment mechanism 40 and the body posture information detected by the body posture information collection module 22 to determine whether the vehicle is in a dangerous area on the beach. When it is in a dangerous area, an alarm message will be issued through the sound and light alarm 502, and the output power of the motor 44 will be adjusted at the same time to control the driving speed and give the driver enough time to change direction.

[0054] In order to prevent human damage to the power circuit of the electromagnet 302, the device is provided with a remote control mechanism 60. The electromagnet circuit detection unit 601 in the remote control mechanism 60 can detect whether the power circuit of the electromagnet 302 is damaged by human beings. Damage to the power circuit will make it impossible to disconnect the direct connection between the speed control handle 46 and the controller 43. Therefore, the electromagnet circuit detection unit 601 is provided to detect the power state of the power circuit of the electromagnet 302 in real time to determine whether the power circuit is damaged. When the electromagnet circuit detection unit 601 detects that the circuit is damaged, it sends data information to the controller 43. The controller 43 sends the damage information to the external host computer through the wireless communication module 503 to notify the staff to arrive at the scene in time to control the destroyers and repair the vehicle. To improve safety, the controller 43 will also control the operation of the battery circuit disconnection unit 602 in the remote control mechanism 60. The operation of the battery circuit disconnection unit 602 disconnects the power circuit between the controller 43 and the inverter 42, so that the motor 44 is powered off and stops running, thereby preventing the destroyers from accelerating and leaving the scene, and the use effect is good.

[0055] In one embodiment of the present invention, Figure 7 As shown, it also includes a driving charging mechanism 5 arranged on the chassis of the beach vehicle body 1, and the driving charging mechanism 5 includes a vibration generator 51, a rectifier regulator 52 and a sub-battery 53, wherein the vibration generator 51, the rectifier regulator 52 and the sub-battery 53 are respectively arranged on the chassis of the beach vehicle body 1; the rectifier regulator 52 is connected to the vibration generator 51 and the sub-battery 53 respectively, and the sub-battery 53 is connected to the main battery 41; the vibration generator 51 is used to generate alternating current through the rotation of the tire, and transmit the alternating current to the rectifier regulator 52, the rectifier regulator 52 is used to convert the alternating current into direct current, and transmit the direct current to the sub-battery 53, the sub-battery 53 is connected to the main battery 41 through a DC-DC converter to supply power to the main battery 41, and an electromagnetic control switch is provided on the wire between the DC-DC converter and the main battery 41, and the opening and closing of the electromagnetic control switch is controlled by the controller 43.

[0056] It should be noted that the vibration generator 51, the rectifier regulator 52 and the sub-battery 53 described in this embodiment are all existing technologies, so they will not be described in detail here.

[0057] Specifically, during the driving of the vehicle, the driving charging mechanism 5 can capture and utilize the kinetic energy of the vehicle, convert it into electrical energy for storage, thereby realizing the continuous utilization of energy. When the stored electrical energy is added to the main battery 41, it provides additional energy support for the main battery 41, thereby extending the vehicle's cruising range, improving the overall energy efficiency ratio, and having a good use effect. During driving, the vibration generator 51 is used to generate alternating current through the rotation of the tires, and transmit the alternating current to the rectifier regulator 52. The rectifier regulator 52 is used to convert the alternating current into direct current, and transmit the direct current to the sub-battery 53. The sub-battery 53 is connected to the main battery 41 through a DC-DC converter to supply power to the main battery 41. When the vehicle is not stopped and the engine is not turned off, the electromagnetic control switch is in a closed (disconnected) state, and the sub-battery 53 cannot supply power to the main battery 41 through the DC-DC converter. After the vehicle is stopped and the engine is turned off, the electromagnetic control switch is in an open (closed) state, and the sub-battery 53 can supply power to the main battery 41 through the DC-DC converter.

[0058] In one embodiment of the present invention, Figure 8As shown, it also includes a driving state detection device 6 arranged on the chassis of the beach vehicle body 1, and the driving state detection device 6 includes a vehicle speed sensor 61, a voltage sensor 62 and a key position sensor 63, wherein the vehicle speed sensor 61 is fixedly connected to the chassis of the beach vehicle body 1, and is used to detect the current speed of the vehicle, the voltage sensor 62 is fixedly connected to the main battery 41, and is used to detect the current voltage of the main battery 41, and the key position sensor 63 is arranged inside the beach vehicle body 1, and is used to detect the rotation angle of the vehicle key, and the output ends of the vehicle speed sensor 61, the voltage sensor 62 and the key position sensor 63 are respectively connected to the input end of the controller 43.

[0059] It should be noted that the key position sensor 63 described in this embodiment is an angle sensor.

[0060] It should also be noted that the vehicle speed sensor 61 , the voltage sensor 62 and the key position sensor 63 are all prior art, and thus will not be described in detail here.

[0061] Specifically, to ensure the safety of charging, the sub-battery 53 can only supply power to the main battery 41 when the vehicle is stopped and the ignition is turned off. In order to detect whether the vehicle is in a stopped and ignition-off state, the device is provided with a vehicle speed sensor 61, a voltage sensor 62 and a key position sensor 63. The vehicle speed sensor 61 is used to detect the current speed of the vehicle. When the detected speed is zero, it can be preliminarily determined that the vehicle is in a stopped state. The voltage sensor 62 is used to detect the current voltage of the main battery 41. When the voltage of the main battery 41 drops to a certain threshold, it can be further determined that the vehicle is in a stopped state. The key position sensor 63 is used to detect the rotation angle of the vehicle key. The key position sensor 63 is an angle sensor. When the angle sensor detects that the current key angle corresponds to the angle that the key should be at when the vehicle is turned off, it can be determined that the vehicle is in an ignition-off state. When all of the above three conditions are met, the controller 43 controls the electromagnetic control switch to open (close). After the electromagnetic control switch is opened (closed), the wires between the sub-battery 53, the DC-DC converter and the main battery 41 are connected, and the sub-battery 53 can supply power to the main battery 41. By utilizing the power stored in the sub-battery 53, a higher energy efficiency ratio can be obtained, and the use effect is good.

[0062] In summary, an intelligent electric beach vehicle according to an embodiment of the present invention can automatically and intelligently cut off the direct connection between the speed control handle 46 and the controller 43 when driving in the high resistance environment of the beach, and the controller 43 takes over the control of the motor 44. Through the preset speed parameters, the controller 43 can accurately control the motor 44 to operate at a constant and optimized speed, thereby driving the vehicle to travel smoothly and efficiently at the set speed. This setting effectively curbs the driver's frequent sudden acceleration operations on the beach due to impulse or habit, fundamentally reduces unnecessary loads on the power system and the rapid consumption of battery power, and achieves a significant improvement in energy efficiency.

[0063] Example 2 When the beach car faces a harsh environment, a backup system is added to the electromagnetic switching mechanism 30: a shape memory alloy switching mechanism, which is arranged in parallel with the electromagnetic switching mechanism 30. This design can greatly improve the reliability of the system.

[0064] Structure composition: a) Shape memory alloy drive element: Made of nickel-titanium alloy (Nitinol), it has excellent corrosion resistance and fatigue strength.

[0065] b) Thermoelectric coolers: used to rapidly heat and cool shape memory alloys.

[0066] c) Mechanical linkage rod: connects the shape memory alloy driving element and the switching contact.

[0067] d) Elastic reset element: used to reset the system when the shape memory alloy cools down.

[0068] e) Sealed housing: Made of waterproof, dustproof and high temperature resistant composite material to protect internal components.

[0069] f) Shape memory alloy temperature sensor: monitors the temperature of shape memory alloy.

[0070] g) Memory alloy position sensor: accurately detect switching status.

[0071] Working principle: When the shape memory alloy is heated to the transition temperature, a phase change occurs, resulting in a change in shape, which drives the mechanical linkage to move. After cooling, the system returns to its initial state under the action of the elastic reset element.

[0072] Control system: a) Microprocessor: controls the operation of the entire shape memory alloy switching mechanism.

[0073] b) Current control module: Precisely controls the current flowing through the shape memory alloy to achieve precise temperature control.

[0074] c) Status monitoring module: real-time monitoring of the system's working status and environmental conditions.

[0075] Switching strategy: Under normal circumstances, the electromagnetic switching mechanism 30 serves as the main working system.

[0076] The system automatically switches to the shape memory alloy switching mechanism when the following conditions are detected: 1. The electromagnetic switching mechanism 30 fails or its performance deteriorates.

[0077] 2. The ambient humidity or salinity exceeds the preset threshold.

[0078] 3. Excessive temperature may affect the performance of the electromagnetic system.

[0079] This design greatly improves the reliability and environmental adaptability of the entire switching system by introducing a shape memory alloy switching mechanism as a backup system. It not only provides stable performance in harsh beach environments, but also has advanced functions such as self-adaptation, self-diagnosis, and predictive maintenance. This innovative design provides a more reliable and efficient control solution for smart electric beach cars, effectively solving the challenges brought by seawater and high temperature environments.
