[0024] The embodiments of the present application will be described in detail below with reference to the drawings.
[0025] Embodiment: As Figures 1 to 5As shown, an integrated electrical box is mainly composed of components such as a box body 1, a box cover 6, a circuit board 2, a relay 4 and a fuse 3. In order to facilitate the inspection and maintenance of the components inside the electrical box, the box body 1 and the box cover 6 are designed to be detachable in this embodiment. Specifically, they can be connected by bolts or other methods. In order to protect the components inside the electrical box and reduce the impact of the external environment on the components inside the electrical box, the box cover 6 is adapted to the box body 1 so that the box cover 6 can be installed in the opening of the box body 1 to form an installation space. The circuit board 2 serves as a carrier of electronic components, and realizes specific functions and controls through the combination and arrangement of components. The circuit board 2, relay 4 and fuse 3 are all installed in the box body 1. In order to arrange the components inside the electrical box in an orderly manner and facilitate observation by maintenance personnel, in this embodiment, a relay slot 2-1 and a fuse slot 2-2 are provided on the above-mentioned circuit board 2. The above-mentioned relay slot 2-1 and the above-mentioned fuse slot 2-2 are both multiple. Correspondingly, there are multiple relays 4 and fuses 3. The above-mentioned relay 4 can be directly plugged into the above-mentioned relay slot 2-1, and the above-mentioned fuse 3 can be directly plugged into the above-mentioned fuse slot 2-2, which is simple and convenient and reduces the difficulty of operation. Then, by integrating the circuit with multiple fuses 3 and multiple relays 4, the fuses and relay control circuits required for engines such as National II, National IV and Euro V are arranged together, so that the electrical box can expand its scope of use and meet the needs of different types of engines. Moreover, due to the integrated circuit design, it is convenient for later maintenance and reduces maintenance costs, which is conducive to the promotion and application of the above-mentioned integrated electrical box in the market.
[0026] In order to provide circuit protection in a timely manner, a fuse clip 5 is further provided in the box body 1 in this embodiment. The fuse clip 5 can quickly cut off the circuit to prevent overcurrent from flowing through the circuit and equipment, thereby preventing overload and damage to the equipment. By limiting the current, the fuse clip 5 can effectively prevent fire or other dangerous situations in the circuit, ensuring the safety of the electrical box during use. In order to prevent the fuse clip 5 from affecting other components inside the electrical box, in this embodiment, a mounting position 2-3 for accommodating the fuse clip 5 is provided on the circuit board 2. Specifically, the mounting position 2-3 has two parts, one of which is for the head of the fuse clip 5, i.e., the clamping part, and the other part is for the tail of the fuse clip 5, i.e., the end opposite to the clamping part, to be embedded, thereby ensuring the stability of the fuse clip 5 during installation and use. The mounting position 2-3 is arranged near the corners of the circuit board 2 for easy removal.
[0027] To ensure the stability of the entire electrical box during installation and use, while also ensuring its structural strength and service life, a base 1-1 is integrally formed at the bottom of the box body 1 in this embodiment. The base 1-1 is in the shape of an ear seat and is intended to facilitate securing its position. The base 1-1 has mounting holes 1-1-1 for receiving fixings, which can be bolts or the like, which have a simple structure and are economical and practical. To facilitate loading and unloading, a handle 1-2 is provided on the side of the box body 1. There can be two handles 1-2, one on each side of the box body 1. During actual production, the manufacturer can lift the entire electrical box to prevent the internal components from being affected by lifting.
[0028] The box body 1 is also equipped with a detection control chip, which can provide safety functions such as overcurrent protection, overtemperature protection, battery protection and management, ensuring that the electrical box and connected electrical equipment can respond in time under abnormal circumstances to avoid damage and potential safety risks.
[0029] A connector 7 is also provided on the exterior of the electrical box. This connector 7 allows for quick and easy connection and disconnection of circuits, facilitating installation, maintenance, and repair work. It allows the electrical box to be easily connected to external circuits or devices without the need for complex soldering or fixed connections. By using connector 7, circuits can be connected and disconnected without directly accessing the main power cord, reducing the risk of electric shock and hazardous operations.
[0030] In this embodiment, there are three relays 4 and eleven fuses 3. Specifically, the relays 4 are a combination of two or more of a start relay, a preheating relay, a power relay, an ECU relay, and an ON gear relay. The relays 4 and the fuses 3 are both plugged into designated positions, namely, the relay slot 2-1 and the fuse slot 2-2.
[0031] like Figure 5 As shown, when adapting to a National II engine: Wire the power relay, preheat relay, and start relay according to the circuit diagram. Since the preheat function requires timing, ground the microcontroller timing control line. The microcontroller outputs a low level, causing the preheat relay to operate for 13 seconds before disconnecting. Connect the negative preheat control pin to the instrument panel's preheat indicator. After power is applied, the instrument panel's preheat indicator will illuminate for 13 seconds before turning off, indicating that preheat is complete and the engine can be started.
[0032] When using a China IV or Euro V high-pressure common rail engine: In addition to the above, install the ON relay, ECU relay, and optional relays 1 and 2. The preheat function does not require a timing control line. The preheat control negative is connected to the ECU, which controls the preheat duration based on the water temperature or ambient temperature. This design facilitates expansion and maintenance of the electrical box, simplifies the overall vehicle electrical design, and enhances the overall wiring harness aesthetics.
[0033] An integrated electrical box in this embodiment has an ingenious structure. By designing the box body 1 and the box cover 6 to be detachable, it is convenient to subsequently inspect and maintain the components inside the electrical box, reducing the difficulty. A circuit board 2 is provided in the electrical box, and a relay slot 2-1 for the relay 4 to be plugged in and a fuse slot 2-2 for the fuse 3 to be plugged in are provided on the circuit board 2. The relay 4 is plugged into the relay slot 2-1 and the fuse 3 is plugged into the fuse slot 2-2, thereby realizing the installation of the relay 4 and the fuse 3, reducing the difficulty of assembly. There are multiple relay slots 2-1 and fuse slots 2-2, and correspondingly, there are multiple relays 4 and fuses 3. Then, by integrating the circuit with multiple fuses 3 and multiple relays 4, the fuses and relay control circuits required for engines such as National II, National IV and Euro V are arranged together, so that the electrical box can expand its scope of use and meet the needs of different types of engines. In addition, due to the integrated circuit design, it is convenient for subsequent maintenance and reduces maintenance costs, which is conducive to the promotion and application of the above-mentioned integrated electrical box in the market.
