[0002] A vehicle inverter is a device that converts vehicle direct current (DC) into alternating current (AC). It is generally used in electric vehicles (EV) or plug-in hybrid electric vehicles (PHEV) to support the normal operation of vehicle electrical equipment (such as air conditioners, refrigerators, TVs or lamps).

[0003] The vehicle inverter in the related technology is usually plugged into the interface of the car cigarette lighter. During the normal driving of the vehicle by the driver, the road conditions are relatively complicated, so the vehicle inverter plugged into the plug interface of the car cigarette lighter may be disconnected and need to be re-plugged. The frequent disconnection and plugging will cause wear and tear on the plug-in positions of the vehicle inverter and the cigarette lighter, resulting in poor contact between the vehicle inverter and the cigarette lighter and burning the fuse, thereby affecting the stability of the entire vehicle electrical system.

[0026] A vehicle inverter is a device that converts vehicle direct current (DC) into alternating current (AC). It is generally used in electric vehicles (EV) or plug-in hybrid electric vehicles (PHEV) to support the normal operation of vehicle electrical equipment (such as air conditioners, refrigerators, TVs or lamps).

[0027] The vehicle inverter in the related technology is usually plugged into the interface of the car cigarette lighter. During the normal driving of the vehicle by the driver, the road conditions are relatively complicated, so the vehicle inverter plugged into the plug interface of the car cigarette lighter may be disconnected and need to be re-plugged. The frequent disconnection and plugging will cause wear and tear on the plug-in positions of the vehicle inverter and the cigarette lighter, resulting in poor contact between the vehicle inverter and the cigarette lighter and burning the fuse, thereby affecting the stability of the entire vehicle electrical system.

[0028] Based on this, in order to improve the problem in the related technology that the connection positions of the vehicle inverter and the cigarette lighter may be frequently disconnected and plugged in due to complex driving conditions, which may lead to poor contact at the connection position and burn out the fuse, thereby affecting the stability of the vehicle electrical system, the embodiment of the present application provides the following solution.

[0029] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a vehicle inverter 100, which is used to be plugged into a plug interface of a cigarette lighter. The vehicle inverter 100 includes an insulating base 10, an anti-disconnection component 20 and an inverter connection component 30, wherein: The insulating base 10 is used to be fixedly mounted on the outside of the cigarette lighter.

[0030] The anti-disconnection component 20 is fixedly arranged on the top of the insulating base 10 and is used to be located above the plug interface; the anti-disconnection component 20 has a receiving space 2101, and the receiving space 2101 is used to be located above the plug interface.

[0031] The inverter connection component 30 is arranged in the accommodating space 2101 and is used to be plugged into the plug interface and is in a plugged state; the inverter connection component 30 is used to convert the direct current output by the cigarette lighter into alternating current in the plugged state.

[0032] The anti-disconnection component 20 is used to keep the inverter connection component 30 located in the accommodating space 2101 in a plugged state with the plug interface.

[0033] It can be understood that the insulating base 10 is a structure capable of fixing the anti-disconnection component 20, for example, it can be composed of a base and a cylindrical structure fixed on the base, wherein the base can be a disk, and a circular hole larger than the diameter of the plug interface is provided at the center of the disk, and the cylindrical structure fixed on the base can be composed of an upper ring, a lower ring, and a plurality of rod-shaped structures connecting the upper and lower rings, and the plurality of rod-shaped structures are arranged at intervals along the circumference of the upper ring or the lower ring. The plurality of rod-shaped structures are arranged at intervals so that the heat generated by the inverter and the plug interface can be dissipated in time, reducing the heat accumulation and improving the service life. The inverter connection component 30 can convert the 12V or 24V DC output of the cigarette lighter into 110V or 220V AC.

[0034] As can be seen from the above, the vehicle inverter 100 and the vehicle provided in the embodiment of the present application, because the insulating base 10 is fixedly installed on the outside of the cigarette lighter, it is more firmly installed on the outside of the cigarette lighter, which can provide good support and reference for the anti-disconnection component 20 and the inverter connection component 30; the anti-disconnection component 20 is fixedly arranged on the top of the insulating base 10, and the anti-disconnection component 20 is prevented from falling off under the action of the insulating base 10, which helps to improve stability; the inverter connection component 30 can be more firmly and firmly plugged into the plug interface of the cigarette lighter by cooperating with the anti-disconnection component 20, thereby Prevent the vehicle inverter 100 from falling off or disconnecting from the plug interface of the cigarette lighter; the inverter connecting component 30 is inserted into the accommodating space 2101 of the anti-disconnection component 20 and then plugged into the plug interface. Since the anti-disconnection component 20 is fixed on the top of the insulating base 10, and the insulating base 10 is fixedly installed on the outside of the cigarette lighter, the vehicle inverter 100 can be prevented from being disconnected from the plug interface when the car is running, reducing the wear between the vehicle inverter 100 and the cigarette lighter, and reducing the situation where the fuse is burned due to poor contact between the vehicle inverter 100 and the cigarette lighter, so as to improve the stability and reliability of the vehicle electrical system.

[0035] In some embodiments, see Figure 3 The anti-disconnection component 20 has a plurality of anti-disconnection components 21; the plurality of anti-disconnection components 21 are sequentially arranged along the circumference of the insulating base 10 and are detachably arranged on the insulating base 10; the plurality of anti-disconnection components 21 are enclosed on the outside of the inverter connecting component 30 and form a receiving space 2101; the anti-disconnection component 21 includes an anti-disconnection body 211 and a pressing component 212, wherein: The anti-break body 211 is fixedly disposed on the top of the insulating base 10 ; the anti-break body 211 is used to prevent the inverter connecting component 30 from moving to a side away from the cigarette lighter.

[0036] The pressing component 212 is located in the accommodating space 2101 and is arranged on the anti-break body 211; the pressing component 212 is used to continuously press the inverter connecting component 30 toward the plug interface position so that the inverter connecting component 30 in the accommodating space 2101 remains in a plugged state with the plug interface.

[0037] The anti-breakage body 211 of each anti-breakage assembly 21 is enclosed on the outside of the inverter connecting component 30 to form a receiving space 2101 .

[0038] It can be understood that the anti-break body 211 is a structure that can prevent the inverter connection component 30 from being disconnected from the plug interface position, for example, it can be an arc-shaped structure that is at an angle with the inverter connection component 30, and the angle is less than 90 degrees and greater than 0°, etc., but is not limited to this. The pressing component 212 is a component that can continuously press the inverter connection component 30 toward the plug interface position, for example, it can have a pressing structure, an elastic member 2122 connected to the pressing structure, and a supporting structure that drives the elastic member 2122 and the pressing structure to rotate, etc. The pressing structure can be a block structure, the elastic member 2122 can be a guide rail and a spring installed on the guide rail, and the supporting structure can be a cylindrical structure, etc., but is not limited to this.

[0039] In this arrangement, the inverter connection component 30 is inserted into the receiving space 2101 formed by the anti-breaking body 211 of each anti-breaking component 21 and then plugged into the plug interface. The pressing component 212 located in the receiving space 2101 and arranged on the anti-breaking body 211 continuously presses the inverter connection component 30 toward the plug interface position, so that the inverter connection component 30 in the receiving space 2101 and the plug interface remain plugged in, which can effectively prevent the inverter connection component 30 from moving away from the cigarette lighter. The pressing component 212 continuously presses the inverter connection component 30 to the plug interface position, further enhancing the connection stability between the inverter and the cigarette lighter plug interface, avoiding power outages and ignition problems caused by looseness, and ensuring stable operation of the inverter. If a certain anti-breaking component 21 is damaged, it only needs to be replaced alone, without replacing the anti-disconnection component 20 as a whole, which improves maintenance efficiency and reduces maintenance costs. Since multiple groups of anti-break components 21 are enclosed to form a accommodating space 2101, by adjusting the number and spacing of the anti-break components 21 and the elastic force of the pressing component 212, etc., it is possible to easily adapt to inverter connecting components 30 of different sizes and shapes, thereby improving the compatibility of the anti-disconnection component 20 and enabling the vehicle inverter 100 to adapt to plug interfaces of cigarette lighters of different calibers.

[0040] Since multiple groups of anti-breaking components 21 are arranged at intervals along the circumference, an all-round protective structure is formed. No matter what direction of force is generated during the driving of the vehicle, the corresponding anti-breaking components 21 can play a role. For example, when the vehicle turns, centrifugal force will be generated. The anti-breaking component 21 located on one side of the centrifugal force direction will provide lateral support force and downward pressure force for the inverter connection component 30 through the anti-breaking body 211 and the downward pressure component 212 to prevent it from deviating to one side due to the centrifugal force, causing the connection between the inverter connection component 30 and the plug interface to loosen or disconnect. The all-round protection mechanism greatly improves the connection stability of the vehicle inverter 100 under complex driving conditions, so that it can continue to work normally; when the vehicle is driving, if the inverter connection component 30 is subjected to force as a whole, at this time, multiple groups of anti-breaking components 21 can work at the same time to quickly eliminate the force on the inverter connection component 30 as a whole, and reduce the force on the vehicle inverter 100, the plug interface of the cigarette lighter or the vehicle.

[0041] Optionally, in some embodiments, see Figure 3 The anti-disconnection component 20 also includes a matching piece 22, which is located in the accommodating space 2101 and is fixedly arranged on the inverter connecting component 30; the pressing assembly 212 includes a mounting piece 2121, an elastic piece 2122 and a pressing piece 2123: The mounting member 2121 is located in the accommodating space 2101 and is rotatably disposed on the anti-breakage body 211 ; when the inverter connecting component 30 is in a plugged state, the axis of the mounting member 2121 is parallel to the axis of the inverter connecting component 30 .

[0042] The elastic member 2122 is located in the accommodating space 2101 ; one end of the elastic member 2122 is fixedly disposed on the mounting member 2121 ; the elastic member 2122 and the mounting member 2121 are coaxial.

[0043] The pressing piece 2123 is located in the accommodating space 2101; the pressing piece 2123 is fixedly arranged at the other end of the elastic piece 2122; the pressing piece 2123 is used to abut against the matching piece 22 to continuously press the matching piece 22 downward toward the plug interface position, so that the inverter connecting component 30 in the accommodating space 2101 remains in a plugged state with the plug interface.

[0044] It can be understood that the mounting member 2121 is a structure that can connect to the elastic member 2122, such as a cylindrical structure, etc., but not limited to this. The elastic member 2122 is a structure that can stretch and shrink, such as a spring and a sleeve that prevents the spring from bending and deforming. The pressing member 2123 can be a structure that can abut the mating member 22, such as a block structure, etc., but not limited to this. The axis of the mounting member 2121 is parallel to the axis of the inverter connecting component 30, and the axis of the mounting member 2121 is the axis of the length direction of the mounting member 2121 toward the plug interface.

[0045] With such a configuration, the elastic member 2122 is pulled away from the plug interface, and the elastic member 2122 is in a compressed state. The pressing member 2123 connected to the elastic member 2122 is placed on the mating member 22, and then the elastic member 2122 is released. Since the elastic member 2122 is no longer subjected to force, the pressing member 2123 in a compressed state is reset to a position close to the plug interface to abut against the mating member 22. The mating member 22 continues to move toward the plug interface under the action of the reset force, and the inverter connection component 30 is continuously connected to the plug interface of the cigarette lighter. If the connection becomes loose due to some external force, the reset force of the elastic member 2122 will automatically push the inverter connection component 30 to be re-crimped, so that the owner does not need to intervene too much, reducing the complexity of the operation and the dependence on the user. Among them, when the vehicle is running, the body of the vehicle will generate a severe impact force. At this time, the elastic member 2122 can play a buffering role and absorb part of the impact force. Because there are multiple sets of anti-break components 21, there are multiple sets of downward pressure components 212. At this time, part of the impact force can be buffered and absorbed to prevent the inverter connecting component 30 from being directly thrown out of the plug interface due to the huge impact force, thereby reducing the harm to the people in the car and protecting the inverter and the vehicle cigarette lighter interface from damage to a certain extent.

[0046] Optionally, in some embodiments, see Figure 6 The matching member 22 is provided with an entrance 2201 , an adjustment space 2202 and a placement space 2203 ; the placement space 2203 is connected with the accommodating space 2101 through the adjustment space 2202 and the entrance 2201 ; the pressing member 2123 is located in the placement space 2203 through the entrance 2201 .

[0047] It can be understood that the fitting 22 can be composed of a circular plate structure and a conical structure installed with the circular plate structure, an inlet 2201 is opened in the middle of the circular plate structure, and an adjustment space 2202 and a placement space 2203 are opened on the conical structure.

[0048] With such arrangement, the elastic member 2122 is in a compressed state during installation, and the pressing member 2123 connected to the elastic member 2122 enters the adjustment space 2202 through the entrance 2201. By rotating the mounting member 2121, the mounting member 2121 drives the elastic member 2122 and the pressing member 2123 to rotate. After rotating to a certain angle, the pressing member 2123 passes through the adjustment space 2202 and enters the prevention space. At this time, the elastic member 2122 is released, and the elastic member 2122 in a compressed state drives the pressing member 2123 to be located in the prevention space through the restoring force, and abuts against the pressing fitting member 22, so that the inverter connecting component 30 is continuously connected to the plug interface of the cigarette lighter. When the vehicle is on a slope or the vehicle body is tilted due to special road conditions, the inverter connecting component 30 will be affected by gravity. The conical structure of the matching component 22 and the adjustment space 2202 can enable the pressing piece 2123 to continuously push the matching component 22 in the force direction through the adjustment space 2202 under the action of gravity, so that the pressing piece 2123 is always tightly against the matching component 22, maintaining a stable connection between the inverter connecting component 30 and the plug interface.

[0049] Optionally, in some embodiments, please refer to Figures 1 to 3 The anti-break body 211 includes a first section 2111 and a second section 2112. The first section 2111 is detachably disposed on the top of the insulating base 10; the mounting member 2121 is rotatably disposed on the first section 2111. The second section 2112 is fixed to a side of the first section 2111 away from the mating member 22; the first section 2111 and the inverter connecting member 30 form an angle, and the angle is less than 90 degrees and greater than 0 degrees.

[0050] Among them, when the inverter connecting component 30 is in the plug-in state, the first section 2111 of the anti-break body 211 of each anti-break component 21 encloses a conical accommodating space 2101, and the diameter of the opening of the accommodating space 2101 close to the plug-in interface is larger than the diameter of the opening at the end away from the plug-in interface; the matching piece 22 is an inverted cone structure, and the diameter of the inverted cone structure close to the plug-in interface is smaller than the diameter of the end away from the plug-in interface; the matching piece 22 is used to abut with the first section 2111 of multiple groups of anti-break components 21 to enclose a conical accommodating space 2101 when the inverter connecting component 30 is away from the plug-in interface.

[0051] It can be understood that the first section 2111 is a structure capable of supporting the second section 2112 and abutting against the mating member 22, for example, it can be an arc-shaped structure forming an angle with the inverter connecting component 30, but is not limited thereto. The second section 2112 can be an arc-shaped structure.

[0052] With such arrangement, when the inverter connection component 30 is subjected to centrifugal force, the inverter connection component 30 is separated from the position away from the plug interface. Since the first section 2111 is detachably arranged on the insulating base 10 and the second section 2112 is fixedly arranged on the first section 2111, when the inverter connection component 30 is moved away from the plug interface and gradually moves, the matching piece 22 also moves with the movement of the inverter connection component 30, and the elastic piece 2122 is compressed. At the same time, the matching piece 22 arranged on the inverter connection component 30 and the first section 2111 of the anti-breaking body 211 of each anti-breaking component 21 are surrounded to form a conical accommodating space 2101 for The elastic member 2122 is no longer subjected to force, and the elastic member 2122 drives the pressing member 2123 to push the matching member 22 to move toward the plug interface, and the inverter connection member 30 continues to be plugged into the plug interface, thereby preventing the inverter connection member 30 from being separated from the plug interface, improving the plugging stability, reducing frequent disconnection and plugging, further reducing the wear caused by the plugging position of the vehicle inverter 100 and the cigarette lighter, and preventing the fuse from burning due to poor contact between the vehicle inverter 100 and the cigarette lighter, thereby improving the stability and reliability of the electrical system. In addition, when the car is driving on a more complex road surface, the car is locked by the friction between the matching member 22 and the accommodating space 2101, so the more complex the road conditions, the greater the bumps and force of the car, and the tighter the friction between the matching member 22 and the accommodating space 2101, which helps to adapt to various road conditions, reduce the interference of the driver or passengers, reduce the impact on the driver, and help improve driving safety.

[0053] Optionally, in some embodiments, see Figure 5 The inverter connecting component 30 includes a plug-in portion 31, an intermediate portion 32, an inverter body 33 and a conductor portion 34, wherein: One end of the plug-in portion 31 is plugged into the plug port.

[0054] The middle portion 32 is located in the accommodating space 2101 ; one end of the middle portion 32 is disposed at the other end of the plug-in portion 31 ; and the matching piece 22 is fixedly disposed on the middle portion 32 .

[0055] The inverter body 33 is disposed at the other end of the middle portion 32 ; the inverter body 33 is electrically connected to the plug-in portion 31 ; the inverter body 33 is used to convert the direct current output by the cigarette lighter into alternating current when in the plug-in state.

[0056] One end of the conductor part 34 is electrically connected to the plug-in part 31 , and the other end of the conductor part 34 is electrically connected to the inverter body 33 .

[0057] When the plug-in portion 31 is in the plug-in state, the second section 2112 is parallel to the middle portion 32; the anti-disconnection component 20 is used to continuously push the middle portion 32 in the accommodating space 2101 toward the plug-in interface to keep the plug-in portion 31 and the plug-in interface in the plug-in state.

[0058] It can be understood that the plug-in portion 31 is a component that can be plugged into the socket, for example, one end of the plug-in portion 31 can be a joint structure, and the plug can be a plug of a power cord, etc., but is not limited to this. The middle portion 32 is a structure that can accommodate electric wires and connect the plug-in portion 31, for example, it can be a cylindrical structure with holes inside, etc., but is not limited to this. The inverter body 33 is a component that can convert direct current into alternating current, for example, it can have a PWM controller, a boost circuit, a rectifier part and an inverter part inside, etc., but is not limited to this. Among them, the inverter body 33 has a socket for plugging in a power supply. The conductor part 34 is a structure that can pass current, for example, it can be a wire, etc., but is not limited to this.

[0059] In this way, the plug-in part 31 is inserted into the accommodating space 2101 and plugged into the plug interface. At this time, the middle part 32 also moves toward the position of the plug-in part 31, and when the plug-in part 31 is plugged into the plug interface, the middle part 32 is located in the accommodating space 2101. After the plug-in part 31 is plugged into the plug interface, the cigarette lighter transmits direct current to the plug-in part 31 through the plug interface, and inputs it into the inverter body 33 through the conductor part 34. The inverter body 33 is used to convert direct current into alternating current. By integrating the plug-in part 31, the middle part 32, the inverter body 33 and the conductor part 34, the structure of the entire vehicle inverter 100 is made more compact, thereby improving the safety of use.

[0060] In some embodiments, see Figure 8 The inverter body 33 includes an inverter housing 331, a conversion member 332, a sensor member 333 and a plurality of ejection members 334; A plurality of plug holes 33101 are provided on the side of the inverter housing 331 facing away from the insulating base 10; each plug hole 33101 has a plug sheet; the electrical appliance plug moves along a first direction A to be plugged into the plug hole 33101 and contact the plug sheet, so that the appliance is powered on; the first direction A is the direction in which the electrical appliance plug moves toward the insulating base 10; the inverter housing 331 is an insulating structure.

[0061] The conversion element 332 is located in the inverter housing 331; the other end of the conductor part 34 is electrically connected to the input end of the conversion element 332, and the current output end of the conversion element 332 is connected to the plug-in piece; the conversion element 332 is used to convert the direct current output by the cigarette lighter into alternating current.

[0062] The sensing component 333 is located in the inverter housing 331 and faces the plug-in piece; the sensing component 333 is used to detect the contact pressure or contact resistance between the electrical appliance plug and the plug-in piece.

[0063] The ejector 334 is located at one side of the plug-in plate; the ejector 334 contacts the electrical appliance when the electrical appliance plug contacts the plug-in plate; when the sensor component 333 detects that the contact area, contact pressure or contact resistance between the electrical appliance plug and the plug-in plate is less than the preset contact area, contact pressure or contact resistance, the ejector 334 ejects the electrical appliance plug from the plug-in hole 33101 along the second direction B, and the electrical appliance plug and the plug-in plate are no longer in contact, so that the electrical appliance is powered off; the ejector 334 is in communication connection with the sensor component 333. Each ejector 334 contacts each plug-in plate.

[0064] It can be understood that the inverter housing 331 is a cylindrical or square structure that can accommodate the conversion component 332, the sensor component 333 and the ejector 334, but is not limited thereto.

[0065] The conversion component 332 is a structure that can convert the direct current output by the cigarette lighter into alternating current, for example, it can be a push-pull DC-AC conversion circuit, a direct current conversion structure composed of a high-frequency transformer (EE35 magnetic core, turn ratio 1:20), a MOSFET switch tube (IRFP260N, 300V / 50A) and an output filter (LC type, cut-off frequency 1kHz), etc., but not limited to this. Among them, the conversion component is also integrated with an information processing module, which can be a microcontroller (MCU) or a microprocessor (MPU), which is used to receive the electrical signal transmitted by the sensor component 333 and send the control signal to the ejector 334; the information processing module is in communication connection with the sensor component 333, the engine control unit (ECU) and the ejector 334.

[0066] The sensing component 333 may be a pressure sensor or a contact sensor, but is not limited thereto. The contact sensor may be detected by a contact impedance detection method, wherein a four-wire detection terminal is provided on the plug-in piece, and the contact impedance is measured in real time by an ADuCM360 microcontroller, and the impedance threshold is set to be greater than 100 mΩ to detect the size of the contact resistance between the electrical plug and the plug-in piece. The pressure sensor may detect the size of the contact pressure between the electrical plug and the plug-in piece by a micro pressure sensor array (FSS1500NST), with a sampling frequency of 200 Hz and an 8-bit ADC resolution.

[0067] The ejector 334 is a component that can push the electrical plug out of the plug hole 33101, and can include, for example, a micro-telescopic motor and a transmission structure connected to the power output end of the micro-telescopic motor. The transmission structure can be a sheet structure or a rod structure with a certain thickness, but is not limited thereto. The transmission structure is in conflict with the electrical plug at one end facing the electrical plug, and the transmission structure faces the plug hole 33101 and moves along the first direction A. When the ejector 334 is working, the power output end of the micro-telescopic motor pushes the transmission structure to move in the plug hole 33101 along the first direction A to push the electrical plug out of the plug hole 33101 along the first direction A. Multiple ejectors 334 are all connected to the sensor component 333 in communication, and the communication connection can be a wired electrical connection or a wireless connection. The plug-in piece in the plug hole 33101 has the same structure as the electrical plug, and is fixed in the inverter housing 331. When the ejector 334 ejects the electrical plug, the plug-in piece remains fixed, and only the electrical plug is ejected.

[0068] With such arrangement, when the car is driving, due to different driving conditions and different passengers, the vehicle may be bumpy during driving, and the electrical plug inserted in the socket 33101 may become loose or have poor contact with the plug-in sheet. At this time, the sensor component 333 will continue to detect the contact pressure or contact resistance between the electrical plug and the plug-in sheet. When the contact pressure or contact resistance between the electrical plug and the plug-in sheet is less than the preset value, the ejector 334 will work to push the electrical plug along the second direction B, disconnect the electrical plug from the plug-in sheet, so that the electrical appliance is powered off, and then actively power off to avoid short circuit or overload of the electrical appliance or cigarette lighter, which can protect the cigarette lighter circuit and the electrical appliance, and automatically eject the plug according to the contact pressure or contact resistance to prevent fire or equipment damage caused by sparks or overheating of the electrical plug, and prevent the danger caused by poor contact between the electrical plug and the plug-in sheet for a long time, thereby reducing the probability of dangerous situations and improving safety.

[0069] For further information, see Figure 8 Because the electricity of the cigarette lighter comes from the battery in the car, and the battery generates electricity by driving the generator after the engine is running, and the battery is charged by the generator, so when the car stops driving, if the electrical appliance is still using electricity, the vehicle inverter 100 also includes a power detection component, which is arranged at the negative pole of the battery and is communicated with the vehicle engine control unit (ECU); when the power detection component detects that the power of the battery is lower than the preset number of engine starts, it sends a signal to the engine control unit (ECU), and the engine control unit (ECU) sends a push-out signal to each ejection member 334, and each ejection member 334 ejects the electrical appliance plug from the plug hole 33101 along the second direction B to cut off the power of the electrical appliance.

[0070] It can be understood that the power detection component is a component that can detect the remaining power inside the battery, for example, it can be a current sensor, and the current sensor can be a Hall effect sensor or a shunt resistor, etc., but not limited to this. The battery power is lower than the preset number of engine starts, which can be understood as the engine needs to consume part of the battery power when starting. Therefore, when the battery is fully charged, the battery capacity and loss degree are different. On average, the battery can start the engine about 10 to 15 times, and the starting current of a gasoline vehicle is about 200-600A.

[0071] With such arrangement, when it is detected that the battery charge is close to the starting threshold (usually 30%-40% of the capacity), the ejector 334 is used to shut down the electrical appliances, thereby ensuring the starting current when the engine is started, and preventing the user from being unable to start the engine and causing great losses to the user; in a low temperature environment, the battery performance of the battery will decay, and thus shutting down the electrical appliances when the battery charge is close to the starting threshold by the ejector 334 can reduce the probability of ignition failure due to cold, avoid complete paralysis of the vehicle due to excessive discharge, improve the availability in emergency situations, prevent excessive discharge of the battery, extend the service life of the battery, and reduce the frequency and cost of battery replacement.

[0072] Optionally, in some embodiments, please refer to Figure 3 and Figure 4 The anti-disconnection component 20 also includes a plurality of anti-swing components 23 and a connecting ring 24. The plurality of anti-swing components 23 are arranged in a gap along the circumference of the middle portion 32 and are fixedly arranged on the outer wall of the middle portion 32. The connecting ring 24 is sleeved on the outside of the middle portion 32; the connecting ring 24 connects the anti-swing components 23. The connecting ring 24 is used to drive the plurality of anti-swing components 23 to be pulled downward to the first section 2111 to cooperate, so as to prevent the plug-in portion 31 from being thrown out of the plug-in interface.

[0073] It can be understood that the anti-swing assembly 23 is a component that can prevent the plug-in portion 31 from being thrown out of the plug-in interface after being subjected to the force of the car, and can have, for example, a fixed structure, an elastic structure connected to the fixed structure, and a resistance structure connected to the elastic structure, wherein the fixed structure can be a cylindrical structure, the elastic structure can be a spring, and the resistance structure can be a block structure, etc., but not limited thereto. The connecting ring 24 can be a component that can drive the anti-swing assembly 23 to move downward, and can be, for example, a ring structure, etc., but not limited thereto.

[0074] In this way, the connection ring 24 is pressed toward the position of the plug interface. Since the connection ring 24 connects the anti-slip components 23, the anti-slip components 23 move toward the plug interface with the pressing force, so that the anti-slip components 23 cooperate with the first section 2111 to prevent the plug part 31 from swinging under the centrifugal force of the car and prevent the plug part 31 from being thrown out of the plug interface. Through the combination of multiple groups of anti-slip components 23 and connection rings 24, multi-level redundant protection is formed. Even if one of the anti-slip components 23 fails due to external force, the other anti-slip components 23 can still continue to play the role of anti-slip, preventing the plug part 31 from being separated from the plug interface, which can effectively avoid single point failures and improve reliability and safety. By arranging multiple groups of anti-swing components 23, the transmission of force can be gradually dispersed to avoid excessive concentration on a single component, thereby balancing the pressure, which not only extends the service life of the anti-swing component 23, but also improves the durability of the overall system and reduces the impact of force on the vehicle inverter 100 to increase the service life; in addition, it can reduce the increase in resistance and energy loss caused by poor contact, so that the inverter body 33 can more efficiently convert the direct current output of the cigarette lighter into alternating current, thereby improving the power conversion efficiency, and for some vehicle-mounted electrical appliances with high requirements for power supply, such as vehicle-mounted refrigerators, vehicle-mounted vacuum cleaners, etc., it helps to provide a more stable connection.

[0075] Optionally, in some embodiments, please refer to Figure 3 , Figure 4 and Figure 7 The first section 2111 is provided with an insertion entrance 211101, a strip opening 211102, a moving space 211103 and a blocking space 211104; the insertion entrance 211101 faces the middle portion 32; the blocking space 211104 is connected to the insertion entrance 211101 through the moving space 211103; the strip opening 211102 is connected to the moving space 211103 and faces the middle portion 32; the anti-slip assembly 23 includes a fixing member 231, an elastic portion 232 and a blocking member 233. The fixing member 231 is fixedly arranged on the outer wall of the middle portion 32. One end of the elastic portion 232 is fixedly arranged on the fixing member 231. The blocking member 233 is located in the blocking space 211104; the blocking member 233 is fixedly arranged on the other end of the elastic portion 232.

[0076] Among them, the elastic part 232 of each anti-swinging component 23 is connected to the connecting ring 24 in sequence and at intervals; the elastic part 232 drives the blocking member 233 from the insertion entrance 211101 through the moving space 211103 to enter the blocking space 211104 and get stuck, so as to prevent the plug-in part 31 from being thrown out of the plug-in interface when the car encounters various complex road conditions.

[0077] In this way, by pressing the connecting ring 24 toward the position of the plug interface, since the connecting ring 24 is connected to the elastic part 232 of each anti-swing-off component 23, the elastic part 232 of each anti-swing-off component 23 moves toward the plug interface position with the pressing force. At this time, the elastic part 232 is compressed, and the blocking member 233 connected to the elastic part 232 enters the moving space 211103 through the insertion entrance 211101. After entering the moving space 211103, the connecting ring 24 is no longer pressed. At this time, the elastic part 232 is no longer subjected to the pressing force to reset, and drives the connecting ring 24 to reset. At this time, under the condition of the return force of the elastic part 232, the blocking member 233 moves through the moving space 211103 to the blocking space 211104 to abut against the first section 2111, thereby preventing the plug-in part 31 from swinging due to the centrifugal force of the car and increasing the risk of being thrown off, thereby preventing the plug-in part 31 from being thrown out of the plug interface. The stability of the plug-in is improved by cooperating between the locking parts 233 of multiple sets of anti-slip components 23 and the locking spaces 211104 in each second section 2112. In the event of an impact, the plug-in portion 31 can quickly return to a stable position with the cooperation of multiple locking parts 233 and the locking spaces 211104, thereby reducing poor contact caused by the vehicle driving on bumpy or bumpy roads, thereby helping to improve the plug-in stability and reliability of the equipment.

[0078] Optionally, in some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The inverter connecting component 30 also includes a torsion piece 35; one end of the torsion piece 35 is fixedly arranged at the other end of the middle part 32, and the other end of the torsion piece 35 is fixedly arranged on the inverter body 33; one end of the conductor part 34 is electrically connected to the plug-in part 31, and the other end of the conductor part 34 is passed through the torsion piece 35 and is electrically connected to the inverter body 33; the torsion piece 35 can be twisted in any direction in the car to adjust the orientation of the inverter body 33.

[0079] It can be understood that the torsion member 35 is a component that can drive the inverter body 33 to move, for example, it can be a bellows-shaped columnar structure with an accommodating hole for accommodating the conductor part 34 inside, wherein the bellows-shaped columnar structure can be made of carbon steel, aluminum alloy or ABS plastic, etc., but is not limited to this.

[0080] With such arrangement, when the co-pilot, rear seat or main driver uses the vehicle-mounted inverter 100, the torsion piece 35 will be twisted to a certain angle by twisting the torsion piece 35. At this time, the inverter body connected to the torsion piece 35 is also twisted to a certain angle, so that the socket on the inverter body 33 can be directed toward the user to prevent the vehicle-mounted inverter 100 from being pulled out of the plug interface when the vehicle-mounted inverter 100 is used. The inverter body 33 can be easily adjusted in direction through the torsion piece 35. The user does not need to move the entire device, but only needs to twist the torsion piece 35 according to the angle required, avoiding the problem of manual movement or re-plugging. Whether in the main driver, co-pilot or rear seat, the user can easily adjust the direction of the inverter to ensure that the socket on the inverter body 33 is always directed toward the user, avoiding the inconvenience caused by inappropriate angles and reducing the situation where the plug cannot be conveniently connected due to different seats. By adjusting the angle of the inverter body 33 through the torsion piece 35, it is possible to effectively avoid loose connection or inverter detachment from the plug interface due to pulling between the device and the socket during use. This helps prevent power disconnection and equipment damage caused by frequent adjustment or movement, and can reduce the pulling on the socket under the action of external force to ensure the stability of the power connection.

[0081] The embodiment of the present application further provides a vehicle, the vehicle comprising the vehicle-mounted inverter of any of the above embodiments. The vehicle can be of various types, such as a fuel vehicle, an electric vehicle, a hybrid vehicle, etc.

[0082] Since the vehicle of the embodiment of the present application adopts the vehicle-mounted inverter of the above embodiment, it also has the technical effects brought by the technical solution of the vehicle-mounted inverter of any of the above embodiments, which will not be repeated here.

[0083] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
