Technical Field
[0001] This utility model relates to the field of inverter technology, specifically to an automatic inverter for vehicles. Background Technology
[0002] An automotive inverter is a device that converts direct current (DC) from a car battery into alternating current (AC) to meet the power needs of various electrical appliances in the vehicle. An existing patent for an automotive inverter, patent publication number CN206790362U, includes a housing; a cooling base plate disposed between the housing and the motor; and a top cover fixed to the upper end of the housing to seal the opening at the upper end of the housing. A capacitor, a power module, a current sensor, and an AC terminal block are fixed on the cooling base plate; a DC terminal block is fixed on the top cover, and the circuit board is positioned above the power module and the current sensor. This invention integrates the power module, its circuit board, capacitor, current sensor, and AC terminal block onto the cooling base plate through a specific positional relationship. The top cover is mounted on the housing, and the DC terminal block is integrated into the inverter's top cover. This reduces the number of busbars and sensor harnesses found in other inverters, resulting in a more compact structure, better heat dissipation, higher electromagnetic compatibility, higher reliability, and compliance with the requirements for axial arrangement with the motor.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although conversion can be achieved through components such as capacitors, the lack of an effective quick-disassembly and assembly structure makes it easy for the inverter to shift and loosen due to the dragging of the wiring harness during placement, resulting in unstable wiring harness connections. Therefore, we propose an automatic inverter for vehicles to solve the above-mentioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-6 The present invention provides a technical solution: an automatic inverter for vehicles, including a housing mechanism 1, the housing mechanism 1 containing at least a power conversion circuit and a control circuit, and a connecting block 3 installed at the bottom of the housing mechanism 1;
[0026] The main body of the connecting block 3 is a rectangular block structure. There are two connecting blocks 3. The outer sides of the two connecting blocks 3 are fixedly connected to two protruding sliders 301. The sliders 301 are protruding from the connecting blocks 3. The bottom plates 3011 are fixedly connected to the bottom surfaces of the two connecting blocks 3. The main body of the bottom plate 3011 is a rectangular plate structure. The bottom surface of the bottom plate 3011 is fixedly connected to an adhesive layer 3012. The bottom end of the adhesive layer 3012 is provided with an adhesive layer.
[0027] By installing a connecting block 3 at the bottom of the housing mechanism 1, and setting a slider 301, a base plate 3011 and an adhesive layer 3012 on the connecting block 3, the inverter can be firmly fixed in the vehicle by the adhesive layer at the bottom of the adhesive layer 3012, preventing displacement and loosening due to the dragging of the wiring harness, and ensuring the stable connection of the wiring harness.
[0028] See Figure 1 , Figure 2 A connector assembly 101 is fixedly connected to the left side of the housing mechanism 1, and a wire assembly 1011 is fixedly connected inside the connector assembly 101;
[0029] By providing a connector assembly 101 on the left side of the housing mechanism 1 and fixing a wire assembly 1011 inside it, current input can be guided, ensuring that the current smoothly enters the inverter.
[0030] See Figure 4 , Figure 5 The wire assembly 1011 is used for input current, and the plug assembly 1012 is fixedly connected to the left side of the wire assembly 1011. The plug assembly 1012 is a cigarette lighter connector.
[0031] By connecting the plug assembly 1012 of the cigarette lighter structure to the left side of the wire assembly 1011, it is easy to connect to the car cigarette lighter interface, so that the inverter can be easily connected to the car power supply.
[0032] See Figure 1 , Figure 2 The top of the housing mechanism 1 has a groove, which is the picking mechanism 2. The inside of the picking mechanism 2 is arranged in a linear array with a three-head interface 201, a two-head interface 2011, and a USB interface 2012.
[0033] By setting a three-headed interface 201, a two-headed interface 2011 and a USB interface 2012 in the access mechanism 2 at the top of the housing mechanism 1, it can be adapted to different types of vehicle electrical appliances to meet diverse power needs.
[0034] See Figure 5 , Figure 6 The three-headed interface 201, the two-headed interface 2011, and the USB interface 2012 are all used for outputting electrical energy;
[0035] By setting the three-head interface 201, the two-head interface 2011, and the USB interface 2012 as power output terminals, AC power is provided to the connected vehicle electrical appliances to ensure their normal operation.
[0036] See Figure 1 , Figure 2The inside of the retrieval mechanism 2 at the top of the housing mechanism 1 is rotatably connected to a cover plate 2013. The main body of the cover plate 2013 is transparent. A guide groove 2015 is provided at the bottom of the housing mechanism 1. A radiator 2016 is fixedly connected to the right side of the housing mechanism 1. A wind duct 2017 is provided on the right side of the radiator 2016.
[0037] By rotating the transparent cover 2013 within the taking mechanism 2, the interface can be shielded from dust when not in use, protecting the interface and extending its service life.
[0038] See Figure 3 , Figure 4 A handle 2014 is fixedly connected to the top surface of the cover plate 2013. The handle 2014 and the cover plate 2013 together form a dustproof structure for the retrieval mechanism 2, and the handle 2014 and the cover plate 2013 together form an opening structure.
[0039] By setting a handle 2014 at the top of the cover plate 2013, which forms an opening structure with the cover plate 2013, it is convenient for users to open and close the cover plate 2013, and the operation is easy and simple.
[0040] When installing the vehicle automatic inverter, first attach the connecting block 3 to the bottom plate 3011 and the adhesive layer 3012 in a suitable position inside the vehicle. Use the adhesive layer at the bottom of the adhesive layer 3012 to firmly attach the inverter and fix it stably. The slider 301 on the outside of the connecting block 3 has a raised structure, which makes it easy to pick up and adjust the position of the inverter during installation, ensuring that the installation process is convenient and stable, and avoiding displacement and loosening due to the dragging of the wiring harness during subsequent use due to improper position.
[0041] When the plug assembly 1012 is inserted into the car cigarette lighter socket, the DC power from the car battery is input through the plug assembly 1012. The current passes through the wire assembly 1011 and the connector assembly 101 in sequence. The wire assembly 1011 guides the current, ensuring that the current is stably and accurately input into the power conversion circuit and control circuit inside the housing mechanism 1, providing a stable power input for subsequent current conversion.
[0042] The DC power entering the housing mechanism 1 is converted into AC power by the power conversion circuit according to the specific circuit design and the working principle of the electronic components. The control circuit is responsible for monitoring and adjusting the working state of the power conversion circuit to ensure that the conversion process is stable and reliable and outputs AC power that meets the standard to meet the power needs of the vehicle's electrical appliances.
[0043] The converted AC power is transmitted to the three-headed interface 201, the two-headed interface 2011 and the USB interface 2012 in the receiving mechanism 2. When the plug of the vehicle electrical appliance is inserted into these interfaces, the AC power will flow into the appliance, providing it with the required power so that the appliance can work normally. This realizes the function of the inverter to convert the DC power of the car battery into AC power to power the appliance.
[0044] When the interface inside the access mechanism 2 is not needed, rotate the cover plate 2013 connected inside the access mechanism 2 to cover the interface. The transparent structure of the cover plate 2013 makes it easy to observe the interface status and also serves to shield and prevent dust, reducing the entry of dust and other impurities into the interface and avoiding the impact of impurity accumulation on the conductivity and service life of the interface. When the interface needs to be used, pull the handle 2014 at the top of the cover plate 2013. Using the opening structure formed by the handle 2014 and the cover plate 2013, the cover plate 2013 can be easily opened for convenient and quick connection of vehicle electrical appliances.
[0045] In summary, this device has multiple interfaces, allowing users to select the appropriate interface based on their specific needs.
[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
