Description

Technical Field

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

[0003] In the related art, a vehicle-mounted inverter is usually plugged into the interface of a cigarette lighter in a vehicle. During the normal driving of the vehicle by the driver, due to the complex road conditions, the vehicle-mounted inverter plugged into the cigarette lighter socket may be disconnected and needs to be re-plugged. Frequent disconnection and re-plugging will cause wear at the plugging position of the vehicle-mounted inverter and the cigarette lighter, resulting in poor contact between the vehicle-mounted inverter and the cigarette lighter and burning out the fuse, thus affecting the stability of the entire vehicle-mounted electrical system.

[0064] A vehicle-mounted inverter is a device that converts vehicle-mounted direct current (DC) into alternating current (AC), and is generally used in electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs) to support the normal operation of vehicle-mounted electrical equipment (such as air conditioners, refrigerators, TVs, or lamps, etc.).

[0065] In-vehicle inverters in the related art are usually plugged into the interface of the cigarette lighter in a vehicle. During the normal driving process of the driver, due to the relatively complex road conditions, the in-vehicle inverter plugged into the cigarette lighter socket may be disconnected and needs to be plugged in again. Frequent disconnection and plugging can cause wear at the plugging position of the in-vehicle inverter and the cigarette lighter, resulting in poor contact between the in-vehicle inverter and the cigarette lighter and burning out the fuse, thus affecting the stability of the entire in-vehicle electrical system.

[0066] Based on this, in order to improve the problem in the related art that due to complex driving road conditions, the connection position between the in-vehicle inverter and the cigarette lighter may be frequently disconnected and plugged in, which may further lead to poor contact at the connection position, burning out the fuse, and thus affecting the stability of the in-vehicle electrical system, the embodiments of the present application provide the following solutions.

[0067] Please refer to Figure 1 and Figure 2 , the embodiments of the present application provide an in-vehicle inverter 100. The in-vehicle inverter 100 is used to be plugged into the socket of the cigarette lighter. The in-vehicle inverter 100 includes an insulating base 10, an anti-disconnection component 20, and an inverter connection component 30, where:

[0068] The insulating base 10 is used to be fixedly installed outside the cigarette lighter.

[0069] The anti-disconnection component 20 is fixedly arranged at the top of the insulating base 10 and is used to be located above the socket; the anti-disconnection component 20 has a receiving space 2101, and the receiving space 2101 is used to be located above the socket.

[0070] The inverter connection component 30 passes through the receiving space 2101 and is used to be plugged into the socket and be in a plugged state; the inverter connection component 30 is used to convert the direct current output by the cigarette lighter into alternating current when in the plugged state.

[0071] Among them, the anti-disconnection component 20 is used to keep the inverter connection component 30 located in the receiving space 2101 in a plugged state with the socket.

[0072] It can be understood that the insulating base 10 is a structure capable of fixedly installing the anti-disconnection component 20. For example, it can be composed of a base and a cylindrical structure fixed on the base. Among them, the base can be a disc, and a circular hole larger than the diameter of the socket is opened at the center of the disc. 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. The plurality of rod-shaped structures are circumferentially spaced along the upper ring or the lower ring. The spaced arrangement of the plurality of rod-shaped structures can enable the heat generated at the positions of the inverter and the socket to be dissipated in time, reducing the situation of heat accumulation, so as to improve the service life. The inverter connection component 30 can convert the 12V or 24V direct current output by the cigarette lighter into 110V or 220V alternating current.

[0073] As can be seen from the above, for the in-vehicle inverter 100 and the vehicle provided by the embodiments of the present application, since the insulating base 10 is fixedly installed outside the cigarette lighter and is more firmly installed outside the cigarette lighter, it can play a good supporting and reference role for the anti-disconnection component 20 and the inverter connection component 30; the anti-disconnection component 20 is fixedly arranged at the top of the insulating base 10, and the insulating base 10 prevents the anti-disconnection component 20 from falling off, which helps to improve stability; through the cooperation with the anti-disconnection component 20, the inverter connection component 30 can be inserted into the socket of the cigarette lighter more firmly and stably, thereby preventing the in-vehicle inverter 100 from falling off or disconnecting from the socket of the cigarette lighter; the inverter connection component 30 is inserted into the socket after passing through the accommodation space 2101 of the anti-disconnection component 20. Since the anti-disconnection component 20 is fixed at the top of the insulating base 10 and the insulating base 10 is fixedly installed outside the cigarette lighter, it can prevent the in-vehicle inverter 100 from disconnecting from the socket during the operation of the vehicle, reduce the wear between the in-vehicle inverter 100 and the cigarette lighter, and reduce the situation where the fuse is burned due to poor contact between the in-vehicle inverter 100 and the cigarette lighter, so as to improve the stability and reliability of the in-vehicle electrical system.

[0074] In some embodiments, please refer to Figure 3 , the anti-disconnection component 20 has multiple anti-disconnection assemblies 21; the multiple anti-disconnection assemblies 21 are arranged at intervals in sequence along the circumferential direction of the insulating base 10 and are detachably arranged on the insulating base 10; the multiple anti-disconnection assemblies 21 enclose the outside of the inverter connection component 30 and form an accommodation space 2101; the anti-disconnection assembly 21 includes an anti-disconnection body 211 and a pressing-down assembly 212, wherein:

[0075] The anti-disconnection body 211 is fixedly arranged at the top of the insulating base 10; the anti-disconnection body 211 is used to prevent the inverter connection component 30 from moving away from the cigarette lighter.

[0076] The pressing-down assembly 212 is located in the accommodation space 2101 and is arranged on the anti-disconnection body 211; the pressing-down assembly 212 is used to continuously press down the inverter connection component 30 towards the socket position, so that the inverter connection component 30 in the accommodation space 2101 remains in a plugged state with the socket.

[0077] Among them, the anti-disconnection bodies 211 of the anti-disconnection assemblies 21 enclose the outside of the inverter connection component 30 and form an accommodation space 2101.

[0078] It can be understood that the anti-disconnection body 211 is a structure capable of preventing the inverter connection component 30 from disconnecting from the insertion interface position. For example, it can be an arc-shaped structure forming an angle with the inverter connection component 30, and the angle is less than 90 degrees and greater than 0°, etc., but not limited to this. The pressing-down component 212 is a component capable of continuously pressing down the inverter connection component 30 towards the insertion interface position. For example, it can have a pressing-down structure, an elastic member 2122 connecting the pressing-down structure, and a supporting structure for driving the elastic member 2122 and the pressing-down structure to rotate, etc. The pressing-down structure can be a block structure, the elastic member 2122 can be a guide rail and a spring installed on the guide rail, the supporting structure can be a cylindrical structure, etc., but not limited to this.

[0079] With such a setting, the inverter connection component 30 passes through the accommodation space 2101 formed by enclosing the anti-disconnection bodies 211 of each anti-disconnection component 21 and then is inserted into the insertion interface. The pressing-down component 212 located in the accommodation space 2101 and arranged on the anti-disconnection body 211 continuously presses down the inverter connection component 30 towards the insertion interface position, so that the inverter connection component 30 in the accommodation space 2101 keeps the insertion state with the insertion interface, which can effectively prevent the inverter connection component 30 from moving away from the cigarette lighter. Moreover, the pressing-down component 212 continuously presses down the inverter connection component 30 to the insertion interface position, further enhancing the connection stability between the inverter and the cigarette lighter insertion interface, avoiding problems such as power-off and sparking caused by loosening, and ensuring the stable operation of the inverter. If a certain anti-disconnection component 21 is damaged, only this component needs to be replaced separately, without the need to replace the anti-disconnection component 20 as a whole, improving the maintenance efficiency and reducing the maintenance cost. Since multiple groups of anti-disconnection components 21 enclose to form the accommodation space 2101, by adjusting the number, spacing of the anti-disconnection components 21 and the elastic force of the pressing-down component 212, etc., it is convenient to adapt to inverter connection components 30 of different sizes and shapes, improving the compatibility of the anti-disconnection component 20, so that the vehicle-mounted inverter 100 can adapt to the insertion interfaces of cigarette lighters with different calibers.

[0080] Since multiple groups of anti-disconnection components 21 are arranged at intervals along the circumferential direction, a comprehensive protection structure is formed. No matter what direction of force is generated during the vehicle driving process, there will be corresponding anti-disconnection components 21 playing a role. For example, when the vehicle turns, a centrifugal force will be generated. The anti-disconnection component 21 on the side of the centrifugal force direction will provide a lateral supporting force and a pressing-down acting force for the inverter connection component 30 through the anti-disconnection body 211 and the pressing-down component 212, preventing it from shifting to one side due to the centrifugal force and resulting in the loosening or disconnection of the connection between the inverter connection component 30 and the insertion interface. The comprehensive protection mechanism greatly improves the connection stability of the vehicle-mounted 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 under an overall force, at this time, multiple groups of anti-disconnection components 21 can work simultaneously to quickly eliminate the force received by the whole inverter connection component 30, reducing the force received by the vehicle-mounted inverter 100, the insertion interface of the cigarette lighter or the vehicle.

[0081] Optionally, in some embodiments, referring to Figure 3 , the anti-disconnection component 20 further includes a fitting 22, the fitting 22 is located in the accommodation space 2101, and is fixedly arranged on the inverter connection component 30; the pressing-down assembly 212 includes a mounting member 2121, an elastic member 2122 and a pressing-down member 2123:

[0082] The mounting member 2121 is located in the accommodation space 2101, and is rotatably arranged on the anti-disconnection body 211; when the inverter connection component 30 is in the plugged state, the axis of the mounting member 2121 is parallel to the axis of the inverter connection component 30.

[0083] The elastic member 2122 is located in the accommodation space 2101; one end of the elastic member 2122 is fixedly arranged on the mounting member 2121; the elastic member 2122 is coaxial with the mounting member 2121.

[0084] The pressing-down member 2123 is located in the accommodation space 2101; the pressing-down member 2123 is fixedly arranged at the other end of the elastic member 2122; the pressing-down member 2123 is used to abut against the fitting 22 to continuously press down the fitting 22 towards the insertion port position, so that the inverter connection component 30 in the accommodation space 2101 remains in the plugged state with the insertion port.

[0085] It can be understood that the mounting member 2121 is a structure capable of connecting the elastic member 2122, for example, it can be a cylindrical structure, etc., but not limited thereto. The elastic member 2122 is a structure capable of stretching and contracting, for example, it can be a spring and a sleeve for preventing the spring from bending and deforming. The pressing-down member 2123 can be a structure capable of abutting against the fitting 22, for example, it can be a block structure, etc., but not limited thereto. The axis of the mounting member 2121 is parallel to the axis of the inverter connection component 30, and the axis of the mounting member 2121 is the axis of the length direction of the mounting member 2121 facing the insertion port.

[0086] Set as such, the elastic member 2122 is pulled towards a position away from the insertion port. At this time, the elastic member 2122 is in a compressed state. The pressing member 2123 connected to the elastic member 2122 is located on the mating member 22. Then, the elastic member 2122 is released. Since the elastic member 2122 is no longer stressed, the pressing member 2123 in the compressed state resets towards the position close to the insertion port to abut against the mating member 22. Under the action of the reset force, the mating member 22 continuously moves towards the position of the insertion port, and the inverter connection component 30 is continuously connected to the insertion port of the cigarette lighter. If the connection becomes loose due to some external forces, the reset force of the elastic member 2122 will automatically push the inverter connection component 30 to re-crimp, so that the vehicle owner does not need to intervene too much, reducing the complexity of the operation and the dependence on the user. Among them, during the moment when force is generated during the driving of the vehicle, the vehicle body will generate a strong 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 anti-breaking components 21, there are multiple pressing components 212. At this time, part of the impact force can be buffered and absorbed, preventing the inverter connection component 30 from being directly thrown out of the insertion port due to the huge impact force, reducing the situation of causing harm to the vehicle occupants, and at the same time protecting the inverter and the vehicle cigarette lighter interface from being damaged to a certain extent.

[0087] Optionally, in some embodiments, please refer to Figure 6 , the mating member 22 is provided with an entrance 2201, an adjustment space 2202, and a placement space 2203; the placement space 2203 is communicated with the accommodation 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.

[0088] It can be understood that the mating member 22 can be composed of a circular plate structure and a conical structure installed with the circular plate structure. The entrance 2201 is provided in the middle of the circular plate structure, and the adjustment space 2202 and the placement space 2203 are provided on the conical structure.

[0089] With such a setting, the elastic member 2122 is in a compressed state during installation. The pressing member 2123 connected to the elastic member 2122 enters the adjustment space 2202 through the inlet 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 a certain angle, the pressing member 2123 enters the prevention space through the adjustment space 2202. At this time, the elastic member 2122 is released. The elastic member 2122 in the compressed state drives the pressing member 2123 to be located in the prevention space through the restoring force, and abuts against the pressing and cooperating member 22, continuously connecting the inverter connection component 30 to the socket of the cigarette lighter. When the vehicle is on a slope or the vehicle body is tilted due to special road conditions, the inverter connection component 30 will be affected by gravity. The conical structure of the cooperating member 22 and the adjustment space 2202 can enable the pressing member 2123 to continuously push the cooperating member 22 in the direction of the force through the adjustment space 2202 under the action of gravity, so that the pressing member 2123 always closely abuts against the cooperating member 22, maintaining the stable connection between the inverter connection component 30 and the socket.

[0090] Optionally, in some embodiments, please also refer to Figures 1 to 3 , the anti-breakage body 211 includes a first section 2111 and a second section 2112. The first section 2111 is detachably disposed at 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 the side of the first section 2111 away from the cooperating member 22; the first section 2111 forms an angle with the inverter connection component 30, and the angle is less than 90 degrees and greater than 0 degrees.

[0091] Wherein, when the inverter connection component 30 is in the plugged state, the first sections 2111 of the anti-breakage bodies 211 of the anti-breakage assemblies 21 enclose a conical accommodation space 2101, and the diameter of the opening at the end of the accommodation space 2101 close to the socket is larger than the diameter of the opening at the end away from the socket; the cooperating member 22 has an inverted conical structure, and the diameter of the inverted conical structure at the end close to the socket is smaller than the diameter of the end away from the socket; the cooperating member 22 is used to abut against the conical accommodation space 2101 formed by enclosing the first sections 2111 of multiple anti-breakage assemblies 21 when the inverter connection component 30 is away from the socket.

[0092] It can be understood that the first section 2111 is a structure that can support the second section 2112 and abut against the cooperating member 22. For example, it can be an arc-shaped structure forming an angle with the inverter connection component 30, etc., but not limited thereto. The second section 2112 can be an arc-shaped structure.

[0093] With such a setting, when the inverter connection component 30 is subjected to centrifugal force, the inverter connection component 30 disengages from the position away from the insertion 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 moves away from the insertion interface and gradually moves, the fitting 22 also moves with the movement of the inverter connection component 30, and the elastic member 2122 is compressed under force. At the same time, the fitting 22 arranged on the inverter connection component 30 contacts the first section 2111 of the anti-breaking body 21 of each anti-breaking component 21 to enclose a conical accommodation space 2101, so as to prevent the inverter connection component 30 from continuing to move away from the insertion interface. After preventing the inverter connection component 30 from continuing to move away from the insertion interface, the elastic member 2122 is no longer under the action of force. At this time, the elastic member 2122 drives the pressing member 2123 to push the fitting 22 to move towards the insertion interface, and the inverter connection component 30 continues to be inserted into the insertion interface, thereby preventing the inverter connection component 30 from disengaging from the insertion interface, improving the insertion stability, reducing frequent disconnection and insertion, further reducing the wear of the insertion position of the vehicle-mounted inverter 100 and the cigarette lighter, and preventing the vehicle-mounted inverter 100 and the cigarette lighter from being in poor contact and burning out the fuse, improving the stability and reliability of the electrical system. In addition, when the vehicle is driving on a more complex road surface, due to the abutting and locking between the fitting 22 and the accommodation space 2101, the more complex the road conditions, the greater the bumping and force of the vehicle, and the tighter the abutting between the fitting 22 and the accommodation 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.

[0094] Optionally, in some embodiments, please refer to Figure 5 , the inverter connection component 30 includes a plugging portion 31, an intermediate portion 32, an inverter body 33 and a conductor portion 34, wherein:

[0095] One end of the plugging portion 31 is plugged into the insertion interface.

[0096] The intermediate portion 32 is located in the accommodation space 2101; one end of the intermediate portion 32 is arranged at the other end of the plugging portion 31; the fitting 22 is fixedly arranged on the intermediate portion 32.

[0097] The inverter body 33 is arranged at the other end of the intermediate portion 32; the inverter body 33 is electrically connected to the plugging portion 31; the inverter body 33 is used to convert the direct current output by the cigarette lighter into alternating current in the plugged state.

[0098] One end of the conductor portion 34 is electrically connected to the plugging portion 31, and the other end of the conductor portion 34 is electrically connected to the inverter body 33.

[0099] Wherein, when the plugging part 31 is in a plugged state, the second section 2112 is parallel to the middle part 32; the anti-disconnection component 20 is used to continuously push the middle part 32 in the accommodation space 2101 towards the plug interface, so that the plugging part 31 remains in a plugged state with the plug interface.

[0100] It can be understood that the plugging part 31 is a component that can be plugged into the plug interface. For example, one end of the plugging part 31 can be a connector structure, and the plug can be the plug of a power cord, etc., but not limited thereto. The middle part 32 is a structure that can accommodate wires and connect the plugging part 31. For example, it can be a cylindrical structure and has holes inside, etc., but not limited thereto. 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 rectification part, an inversion part, etc. inside, but not limited thereto. Among them, the inverter body 33 has a socket for the electrical appliance to be plugged in. The conductor part 34 is a structure that can conduct current. For example, it can be a wire, etc., but not limited thereto.

[0101] With such a setting, the plugging part 31 is passed through the accommodation space 2101 and plugged into the plug interface. At this time, the middle part 32 also moves towards the position of the plugging part 31. When the plugging part 31 is plugged into the plug interface, the middle part 32 is located in the accommodation space 2101. After the plugging part 31 is plugged into the plug interface, the cigarette lighter transmits the direct current to the plugging 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 the direct current into alternating current. By arranging the plugging part 31, the middle part 32, the inverter body 33 and the conductor part 34, the structure of the entire vehicle-mounted inverter 100 is made more compact, improving the use safety.

[0102] In some embodiments, please refer to Figure 8 , the inverter body 33 includes an inverter housing 331, a conversion component 332, a sensing component 333 and a plurality of ejecting components 334;

[0103] A plurality of plugging holes 33101 are provided on the side of the inverter housing 331 facing away from the insulating base 10; each plugging hole 33101 is provided with a plugging piece; the electrical appliance plug moves along the first direction A to be plugged into the plugging hole 33101 and contact the plugging piece, so that the electrical appliance is powered on; the first direction A is the direction in which the electrical appliance plug moves towards the insulating base 10; the inverter housing 331 is an insulating structure.

[0104] The conversion component 332 is located inside the inverter housing 331; the other end of the conductor part 34 is electrically connected to the input end of the conversion component 332, and the current output end of the conversion component 332 is connected to the plugging piece; the conversion component 332 is used to convert the direct current output by the cigarette lighter into alternating current.

[0105] The sensing component 333 is located inside 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.

[0106] The ejector 334 is located on one side of the plug-in piece; the ejector 334 abuts against the electrical appliance when the electrical appliance plug contacts the plug-in piece; when the sensing component 333 detects that the contact area, contact pressure or contact resistance between the electrical appliance plug and the plug-in piece 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 no longer contacts the plug-in piece, so that the electrical appliance is powered off; the ejector 334 is communicatively connected to the sensing component 333. Each ejector 334 abuts against each plug-in piece.

[0107] It can be understood that the inverter housing 331 can be a cylindrical, square structure, etc. that can accommodate the conversion component 332, the sensing component 333 and the ejector 334, but is not limited thereto.

[0108] 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 core, turn ratio 1:20), MOSFET switching tubes (IRFP260N, 300V / 50A) and an output filter (LC type, cut-off frequency 1kHz), etc., but is not limited thereto. Among them, an information processing module is also integrated on the conversion component. The information processing module can be a microcontroller (MCU) or a microprocessor (MPU), which is used to receive the electrical signals transmitted by the sensing component 333 and send control signals to the ejector 334; the information processing module is communicatively connected to the sensing component 333, the engine control unit (ECU) and the ejector 334.

[0109] The sensing component 333 can be a pressure sensor or a contact sensor, etc., but is not limited thereto. The contact sensor can be detected by the contact impedance detection method. Four-wire detection terminals are set on the plug-in piece, and an ADuCM360 microcontroller is used to measure the contact impedance in real time. The impedance threshold is set to be greater than 100mΩ to detect the magnitude of the contact resistance between the electrical appliance plug and the plug-in piece. The pressure sensor can use a micro pressure sensor array (FSS1500NST), with a sampling frequency of 200Hz and an 8-bit ADC resolution, to detect the magnitude of the contact pressure between the electrical appliance plug and the plug-in piece.

[0110] The ejector 334 is a component capable of ejecting the electrical appliance plug from the socket hole 33101. For example, it may include a micro telescopic motor and a transmission structure connected to the power output end of the micro telescopic motor. The transmission structure may be a sheet-like structure or a rod-like structure with a certain thickness, etc., but is not limited thereto. One end of the transmission structure facing the electrical appliance plug abuts against the electrical appliance plug. The transmission structure faces the socket hole 33101 and moves along the first direction A; when the ejector 334 works, the power output end of the micro telescopic motor pushes the transmission structure to move along the first direction A in the socket hole 33101 to eject the electrical appliance plug from the socket hole 33101 along the first direction A. A plurality of ejectors 334 are all communicatively connected to the sensing component 333, and the communicative connection may be a wired electrical connection or a wireless connection. Among them, the socket piece in the socket hole 33101 has the same structure as the electrical appliance plug. The socket piece is fixed in the inverter housing 331. When the ejector 334 ejects the electrical appliance plug, the socket piece remains fixed, and only the electrical appliance plug is ejected.

[0111] With such a setting, when the vehicle is running, due to different driving conditions and different passengers in the vehicle, the vehicle will jolt during driving, and then the electrical appliance plug inserted in the socket hole 33101 may become loose or have poor contact with the socket piece. At this time, the sensing component 333 will continuously detect the contact pressure or contact resistance between the electrical appliance plug and the socket piece. When the value of the contact pressure or contact resistance between the electrical appliance plug and the socket piece is less than the preset value, the ejector 334 will work to eject the electrical appliance plug along the second direction B, disconnect the electrical appliance plug from the socket piece, so that the electrical appliance is powered off, and then actively cut off the power to avoid short circuit or overload of the electrical appliance or the cigarette lighter, which can protect the cigarette lighter circuit and the electrical appliance. Automatically eject the plug according to the contact pressure or contact resistance, prevent the occurrence of fire or equipment damage caused by sparks or overheating of the electrical appliance plug, prevent the danger caused by long-term poor contact between the electrical appliance plug and the socket piece, reduce the probability of dangerous situations, and improve safety.

[0112] Further, please refer to Figure 8 , because the power of the cigarette lighter comes from the vehicle's battery, and the battery generates electrical energy by driving the generator after the engine runs, and the battery is charged by the generator. Therefore, when the vehicle stops running and the electrical appliance is still consuming power continuously, the vehicle-mounted inverter 100 further includes a power detection component. The power detection component is arranged at the negative pole position of the battery and is communicatively connected to 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 start times, it sends a signal to the engine control unit (ECU), and the engine control unit (ECU) sends the ejection signal to each ejector 334, and each ejector 334 ejects the electrical appliance plug from the socket hole 33101 along the second direction B to cut off the power supply of the electrical appliance.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] With such a setting, when pressing the connection ring 24 towards the position of the insertion interface, since the connection ring 24 connects each anti-throw-off component 23, each anti-throw-off component 23 moves towards the insertion interface position along with the pressing force, so that each anti-throw-off component 23 cooperates with the first section 2111 to prevent the insertion part 31 from swaying under the centrifugal force of the vehicle and being thrown out of the insertion interface. Through the combination of multiple groups of anti-throw-off components 23 and the connection ring 24, a multi-level redundant protection is formed. Even if a certain anti-throw-off component 23 fails due to external force, other anti-throw-off components 23 can still continue to play the role of preventing throwing off, preventing the insertion part 31 from detaching from the insertion interface, effectively avoiding single-point failures, and improving reliability and safety. Through the arrangement of multiple groups of anti-throw-off components 23, the transmission of force can be gradually dispersed, avoiding excessive concentration on a single component, thereby balancing the pressure, not only extending the service life of the anti-throw-off components 23, but also improving the durability of the overall system, reducing the impact of force on the vehicle-mounted inverter 100 to extend 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 by the cigarette lighter into alternating current, improving the power conversion efficiency. For some vehicle-mounted electrical appliances with high requirements for power supply, such as vehicle-mounted refrigerators and vehicle-mounted vacuum cleaners, it helps to provide a more stable connection.

[0118] Optionally, in some embodiments, please also refer to Figure 3 , Figure 4 and Figure 7 , the first section 2111 is provided with a placement entrance 211101, a strip-shaped opening 211102, a moving space 211103 and a jamming space 211104; the placement entrance 211101 faces the middle part 32; the jamming space 211104 is communicated with the placement entrance 211101 through the moving space 211103; the strip-shaped opening 211102 is communicated with the moving space 211103 and faces the middle part 32; the anti-throw-off component 23 includes a fixing member 231, an elastic part 232 and a jamming member 233. The fixing member 231 is fixedly arranged on the outer side wall of the middle part 32. One end of the elastic part 232 is fixedly arranged on the fixing member 231. The jamming member 233 is located in the jamming space 211104; the jamming member 233 is fixedly arranged at the other end of the elastic part 232.

[0119] Among them, the elastic parts 232 of each anti-throw-off component 23 are sequentially and spacedly connected to the connection ring 24; the elastic part 232 drives the jamming member 233 to enter the jamming space 211104 through the moving space 211103 from the placement entrance 211101 for jamming, so as to prevent the insertion part 31 from being thrown out of the insertion interface when the vehicle encounters various complex road conditions.

[0120] With such a setting, by pressing the connecting ring 24 towards the position of the insertion interface, since the connecting ring 24 is connected to the elastic parts 232 of the anti-throw-off components 23, the elastic parts 232 of the anti-throw-off components 23 move towards the insertion interface position along with the pressing force. At this time, the elastic parts 232 are compressed, and the latching parts 233 connected to the elastic parts 232 enter the moving space 211103 through the placement openings 211101. After entering the moving space 211103, stop pressing the connecting ring 24. At this time, the elastic parts 232 are no longer under the pressing force and return, driving the connecting ring 24 to return. At this time, under the return force of the elastic parts 232, the latching parts 233 move through the moving space 211103 into the latching space 211104 to abut against the first section 2111, thereby preventing the insertion part 31 from swinging due to the centrifugal force of the vehicle, increasing the risk of throw-off, and further preventing the insertion part 31 from being thrown out of the insertion interface. The latching parts 233 of multiple anti-throw-off components 23 cooperate with the latching spaces 211104 in the second sections 2112 to improve the stability of the insertion. In the case of encountering an impact, the insertion part 31 can quickly return to a stable position under the cooperation of multiple latching parts 233 and latching spaces 211104, reducing the poor contact caused by the vehicle driving on a potholed or bumpy road surface, and thus helping to improve the insertion stability and reliability of the device.

[0121] Optionally, in some embodiments, please also refer to Figure 2 , Figure 3 and Figure 5 , the inverter connection component 30 further includes a torsion member 35; one end of the torsion member 35 is fixedly arranged at the other end of the middle part 32, and the other end of the torsion member 35 is fixedly arranged on the inverter body 33; one end of the conductor part 34 is electrically connected to the insertion part 31, and the other end of the conductor part 34 passes through the torsion member 35 and is electrically connected to the inverter body 33; the torsion member 35 can twist in any direction inside the vehicle to adjust the orientation of the inverter body 33.

[0122] 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 columnar structure in the shape of a corrugated pipe, and has a receiving hole for receiving the conductor part 34 inside. Among them, the columnar structure in the shape of a corrugated pipe can be made of carbon steel, aluminum alloy, ABS plastic, etc., but is not limited thereto.

[0123] With such a setting, when using the in-vehicle inverter 100 in the co-pilot, rear row or driver's seat, by twisting the torsion member 35, the torsion member 35 is twisted to a certain angle. At this time, the inverter main body connected to the torsion member 35 is also twisted to a certain angle, so that the socket on the inverter body 33 can face the user, preventing the in-vehicle inverter 100 from being pulled when using the in-vehicle inverter 100, resulting in the in-vehicle inverter 100 being pulled out of the socket. Through the torsion member 35, the inverter body 33 can be easily adjusted in orientation. The user does not need to move the entire device, but only needs to twist the torsion member 35 at the angle required according to their own needs, avoiding the problems of manual movement or re-plugging. Whether in the driver's seat, co-pilot or rear row, the user can conveniently adjust the direction of the inverter to ensure that the socket on the inverter body 33 always faces the user, avoiding the inconvenience caused by inappropriate angles and reducing the situation where it is inconvenient to access the plug due to different seats. By adjusting the angle of the inverter body 33 through the torsion member 35, it can effectively avoid the loosening of the connection or the disconnection of the inverter from the socket caused by the pulling between the device and the socket during use, helping to prevent power disconnection and device damage caused by frequent adjustment or movement, and reducing the pulling force on the socket under external force, ensuring the stability of the power connection.

[0124] The embodiment of the present application also provides a vehicle, which includes the in-vehicle inverter of any of the above embodiments. The vehicle can be various types of vehicles, such as fuel vehicles, electric vehicles, hybrid vehicles, etc.

[0125] Since the vehicle of the embodiment of the present application adopts the in-vehicle inverter of the above embodiment, it also has the technical effects brought by the technical solutions of the in-vehicle inverter of any of the above embodiments, which will not be elaborated here.

[0126] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
