Description

Technical Field

[0001] This utility model relates to the field of integrated controller technology, specifically a multifunctional all-in-one controller for microcars. Background Technology

[0002] The all-in-one controller for microcars is a core on-board control device that integrates multiple functions such as motor drive, power conversion, and signal processing. It is widely used in electric microvans, mobility scooters, and other vehicle models. By integrating traditionally separate components such as motor controllers, DC-DC converters, and charge / discharge management modules, it reduces wiring connection nodes and installation space. It can efficiently coordinate the power output, energy distribution, and equipment linkage of microcars. It is a key component for improving the integration and operational stability of microcar control systems and is adapted to the compact layout and multi-functional collaboration requirements of microcars.

[0003] During controller operation, frequent plugging and unplugging can cause poor contact in the connectors, leading to excessive local resistance, continuous heating, and the formation of a high-temperature arc. Prolonged high-load operation of power devices can cause heat dissipation imbalance, insulation aging and breakdown, resulting in short-circuit sparks. All of these can ignite open flames. If these flames are not quickly suppressed, they can rapidly ignite the controller's internal plastic casing, wire insulation, and even spread through the wiring to the vehicle's battery pack, causing spontaneous combustion, property damage, and safety hazards.

[0004] Existing fire extinguishing devices are mostly fixed single-point spray designs with limited coverage, making it difficult to deal with fires in different areas inside the controller (such as connectors and power device clusters); the release of extinguishing agents lacks precise control and is prone to secondary damage to electronic components due to excessive spraying. Therefore, it is necessary to redesign a multifunctional micro-vehicle all-in-one controller to address the above problems. Utility Model Content

[0005] One technical problem to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-functional all-in-one controller for micro-vehicles, solving the problems of insufficient fire extinguishing function, easy generation and great harm of open flames, and low heat dissipation efficiency of existing controllers.

[0007] Two technical solutions

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional microcar all-in-one controller, including a controller housing, multiple connectors installed on multiple sides of the controller housing, heat dissipation fins installed inside the controller housing, and the heat dissipation fins contacting the electronic components inside the controller housing, a forced air cooling assembly installed inside the controller housing, a rectangular guide rail fixedly installed on the top surface of the controller housing, a turntable rotatably connected to the top surface of the controller housing via a rotating mechanism, a sliding sleeve fixedly installed on the top surface of the turntable, a sliding rod slidably connected to one end of the sliding sleeve, a nozzle installed at the other end of the sliding rod, a support rod rotatably connected to the bottom surface of the sliding rod, a movable sleeve rotatably connected to the bottom end of the support rod, and the movable sleeve movably connected within the rectangular guide rail, a flame detection sensor fixedly installed on the bottom surface of the sliding rod, a nozzle installed at one end of the sliding rod, and a fire extinguishing assembly installed on the top surface of the turntable, and the fire extinguishing assembly communicating with the nozzle.

[0009] Preferably, the fire extinguishing assembly includes a gas storage chamber, which is fixedly installed on the top surface of the turntable. The gas storage chamber is filled with inert gas, and a micro pump is fixed to and connected to the top surface of the gas storage chamber. The micro pump is connected to the nozzle through a connecting pipe.

[0010] Preferably, the forced air cooling assembly includes an air intake channel, which is installed on one side of the controller housing. Multiple fans are installed in the air intake channel, and the air outlets of the multiple fans correspond to the heat dissipation fins. An exhaust channel is installed on the side of the controller housing away from the air intake channel.

[0011] Preferably, the rotating mechanism includes a protective shell, which is fixedly installed on the top surface of the controller housing. A rotating shaft is rotatably connected to the bottom wall of the protective shell, and the top end of the rotating shaft is concentrically fixedly connected to the bottom surface of the turntable. A driven gear is installed on the outer side of the rotating shaft. A micro motor is installed on the bottom wall of the protective shell, and a drive gear is installed on the outer side of the output shaft of the micro motor. The driven gear meshes with the drive gear.

[0013] Preferably, the pitch circle diameter of the driven gear is greater than that of the driving gear, and the micro motor is a conical rotor motor.

[0014] Three beneficial effects

[0015] Compared with the prior art, this utility model provides a multifunctional all-in-one controller for microcars, which has the following beneficial effects:

[0016] 1. This utility model, through devices such as a rectangular guide rail, turntable, rotating mechanism, nozzle, sliding rod, sliding sleeve, support rod, movable sleeve, fire extinguishing component, and open flame detection sensor, achieves accurate detection and directional fire extinguishing of open flames on the controller. The rotating mechanism drives the turntable to rotate, and with the sliding rod extending and retracting within the sliding sleeve and the support rod and movable sleeve moving along the rectangular guide rail, the nozzle can be aimed at different areas from all directions. The open flame detection sensor monitors in real time, and the fire extinguishing component uses a micro pump to precisely spray inert gas through the nozzle towards the fire source, improving fire extinguishing efficiency and targeting.

[0017] 2. This utility model achieves efficient heat dissipation of the controller housing through forced air cooling components and other devices. The fan in the air intake channel blows external cold air in a directional manner toward the heat dissipation fins that are in contact with the electronic components, quickly removing heat. The hot air is discharged through the exhaust channel, forming continuous convection, effectively reducing the internal temperature and ensuring the stable operation of the electronic components.

[0025] This utility model provides a technical solution for a multifunctional all-in-one controller for micro-vehicles:

[0026] Please see Figures 1-5 A multifunctional micro-vehicle all-in-one controller includes a controller housing 1, multiple connectors 3 installed on multiple sides of the controller housing 1, heat dissipation fins 13 installed inside the controller housing 1 and in contact with electronic components inside the controller housing 1, a forced air cooling component installed inside the controller housing 1, a rectangular guide rail 5 fixedly installed on the top surface of the controller housing 1, a turntable 7 rotatably connected to the top surface of the controller housing 1 via a rotating mechanism, a sliding sleeve 10 fixedly installed on the top surface of the turntable 7, a sliding rod 11 slidably connected to one end of the sliding sleeve 10, a nozzle 12 installed at the other end of the sliding rod 11, a support rod 21 rotatably connected to the bottom surface of the sliding rod 11, a movable sleeve 22 rotatably connected to the bottom end of the support rod 21 and movably connected to the rectangular guide rail 5, a flame detection sensor 23 fixedly installed on the bottom surface of the sliding rod 11, a nozzle 12 installed at one end of the sliding rod 11, and a fire extinguishing component installed on the top surface of the turntable 7 and connected to the nozzle 12.

[0027] It should be noted that, through the rectangular guide rail 5, when the slide rod 11 rotates, the slide rod 11 can freely extend and retract within the sliding sleeve 10 with the cooperation of the support rod 21, thereby ensuring that the nozzle 12 can correspond to the plug 3 on different sides when rotating, and the open flame detection sensor 23 is used to detect whether there is an open flame during the rotation process.

[0028] Furthermore, the fire extinguishing component includes a gas storage chamber 9, which is fixedly installed on the top surface of the turntable 7. The gas storage chamber 9 is filled with inert gas, and a micro pump body 15 is fixed and connected to the top surface of the gas storage chamber 9. The micro pump body 15 is connected to the nozzle 12 through a connecting pipe 16. The inert gas can be heptafluoropropane, and the micro pump body 15 is a booster pump.

[0029] Furthermore, the forced air cooling component includes an air intake channel 8, which is installed on one side of the controller housing 1. Multiple fans 14 are installed inside the air intake channel 8, and the air outlets of the multiple fans 14 correspond to the heat dissipation fins 13. An exhaust channel 4 is installed on the side of the controller housing 1 away from the air intake channel 8. The heat dissipation fins 13 can effectively dissipate heat from electronic components, and the fans 14 can quickly remove the heat accumulated on the heat dissipation fins 13, thus achieving the purpose of rapid heat dissipation.

[0030] Furthermore, the rotating mechanism includes a protective shell 6, which is fixedly installed on the top surface of the controller housing 1. A rotating shaft 17 is rotatably connected to the bottom wall of the protective shell 6, and the top end of the rotating shaft 17 is concentrically fixedly connected to the bottom surface of the turntable 7. A driven gear 18 is installed on the outer side of the rotating shaft 17. A micro motor 19 is installed on the bottom wall of the protective shell 6. A drive gear 20 is installed on the outer side of the output shaft of the micro motor 19, and the driven gear 18 meshes with the drive gear 20.

[0031] Furthermore, the four corners of the rectangular guide rail 5 are all rounded, and multiple mounting brackets 2 are symmetrically installed on both sides of the controller housing 1.

[0032] Furthermore, the pitch circle diameter of the driven gear 18 is longer than that of the drive gear 20, and the micro motor 19 is a conical rotor motor.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] First, the controller is fixed to the corresponding position of the microcar via the mounting bracket 2. Each external device is connected to the circuit via the connector 3 on the side of the controller housing 1. When working, the heat generated by the electronic components is transferred to the heat dissipation fins 13, and the forced air cooling component is started simultaneously: the fan 14 in the air intake channel 8 draws in external cold air and blows it in a direction toward the heat dissipation fins 13. The air carrying heat is discharged from the exhaust channel 4, forming a continuous heat dissipation cycle.

[0035] When fire monitoring is required, the micro motor 19 causes the drive gear 20 to rotate, and through the meshing transmission with the driven gear 18, it drives the rotating shaft 17 and the turntable 7 to rotate slowly. During this process, the slide rod 11 rotates with the turntable 7, the movable sleeve 22 slides along the rectangular guide rail 5, and the support rod 21 pushes the slide rod 11 to extend and retract within the sliding sleeve 10, ensuring that the nozzle 12 is always aligned with the plug area 3 on different sides, and the open flame detection sensor 23 scans and detects synchronously.

[0036] If an open flame is detected, the micro pump 15 immediately starts, pumping the heptafluoropropane in the gas storage chamber 9 into the nozzle 12 through the connecting pipe 16, and accurately spraying it to the ignition point. At the same time, the characteristics of the conical rotor motor cause the turntable 7 to brake quickly, keeping the nozzle 12 continuously aimed at the fire source until the open flame is extinguished, thus achieving the coordinated operation of heat dissipation and fire extinguishing functions.

[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
