DETAILED DESCRIPTION

[0031] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0032] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] like Figures 1-9 As shown, this embodiment provides a top-mounted controller electrical box, including: a box body 1, a box door 2, a bottom plate 3, a controller 4 and an operator 5; an installation cavity 101 is formed inside the box body 1, and the installation cavity 101 opens toward the front end 102, and the outer periphery of the opening 102 is provided with a waterproof folding edge 103; the box door 2 is hinged to one side of the box body 1, and the box door 2 can be flipped relative to the box body 1 to open or close the opening 102; the bottom plate 3 is detachably arranged in the installation cavity 101, and a wire groove 301 and a mounting hole are provided on the bottom plate 3; the controller 4 is connected to the bottom plate 3 through the mounting hole, and an input end interface 401 and an output end interface 402 are provided on the controller 4, and the input end interface 401 and the output end interface 402 are respectively plugged with the wiring harness, and the wiring harness is arranged in the wire groove 301; the operator 5 is electrically connected to the controller 4.

[0035] Based on the above scheme, an installation cavity 101 is formed inside the box body 1 for installing and fixing the upper controller 4 and other electrical components. The front opening 102 of the installation cavity 101 is designed to facilitate the installation and maintenance of the equipment, and the waterproof folding edge 103 on the outer periphery of the opening 102 provides an effective waterproof barrier to prevent external moisture from entering the interior of the electrical box; the box door 2 is hingedly installed on one side of the box body 1 and can be flipped relative to the box body 1 to open or close the opening 102 of the installation cavity 101, making it convenient for operators to maintain and repair the internal equipment without disassembling the entire electrical box; the bottom plate 3 is detachably installed Mounted within mounting cavity 101, it is provided with a wire trough 301 and mounting holes. Wire trough 301 is used to route the wiring harness, keeping the interior of the electrical box neat and orderly while preventing short circuits or malfunctions caused by disorganized wiring. The mounting holes are used to secure electrical components, such as the upper-mounted controller 4, to the base plate 3, ensuring secure installation. Controller 4 is connected to base plate 3 via the mounting holes and is provided with an input interface 401 and an output interface 402. These interfaces connect to external devices or a power source via wiring harnesses to transmit and control electrical signals. The wiring harness is arranged along wire trough 301 on base plate 3, creating an aesthetically pleasing and safe layout. Operator 5 is electrically connected to controller 4 to receive and transmit operational instructions to controller 4. Controller 4 then controls the operation of the upper-mounted equipment based on the instructions received, achieving automated control. Since the base plate 3 is detachable, when it is necessary to add electrical components or adapt the installation of different electrical components, the mounting holes on the base plate 3 and the position of the wire trough 301 can be adjusted for adaptation and assembly. The adjustment mentioned here specifically refers to replacing the base plate 3 so that the mounting holes on the base plate 3 and the position of the wire trough 301 can be more adapted to the electrical components that need to be installed. In this way, there is no need to adjust the installation dimensions of the box body 1 and the entire vehicle, which greatly improves the versatility of the electrical box. In addition, by providing a waterproof folding edge 103 at the opening 102 of the box body 1, the controller 4 and other components installed in the installation cavity 101 can be effectively protected to prevent rainwater from seeping in, and can also prevent the collision of sand and stones.

[0036] At the same time, since the connection between the wiring harness and the controller 4 in the existing electrical box generally adopts the terminal post method, the connection steps are cumbersome and prone to errors. The present application adopts a plug-in method for connection, and the controller 4 itself is a cast aluminum component, which can be effectively waterproof, dustproof and flame retardant, and the cast aluminum controller 4 shell is firm and reliable, meeting the vibration requirements of the vehicle electrical equipment; the controller 4 uses vehicle-mounted anti-loosening and waterproof connectors at the input end interface 401 and the output end interface 402, and the wiring harness uses connector docking to improve the convenience of installation and effectively improve the assembly efficiency.

[0037] Furthermore, the waterproof folding edge 103 is tilted from the inside to the outside, and the tilted setting can be tilted forward or tilted backward. The front here refers to the direction toward the box door 2, and the backward is the opposite direction. The advantage of this design is that it can more effectively prevent rainwater from entering the installation cavity 101.

[0038] In some embodiments, the end face of the box body 1 facing away from the box door 2 is provided with a mounting portion 9, and the box body 1 is fixed to the side of the vehicle through the mounting portion 9. In order to further optimize the installation method and adaptability of the electrical box of the upper-mounted controller 4, a mounting portion 9 is specially provided on the end face of the box body 1 facing away from the box door 2. This design enables the electrical box to be firmly fixed to the side of the vehicle through the mounting portion 9, and whether it is a special sanitation vehicle or other types of special vehicles, it can be flexibly installed according to actual needs. The specific structure and fixing method of the mounting portion 9 can be customized according to the specific situation of the vehicle and the installation environment to ensure the stability and safety of the electrical box. Through such a design, the electrical box not only has good waterproof performance and versatility, but also is more convenient to install and disassemble on the vehicle, improving the overall convenience and flexibility of use.

[0039] Specifically, the mounting portion 9 includes six screws welded to the box body 1 , and the screw size is M8*25.

[0040] Preferably, the door 2 is provided with a folded edge 201 facing inward relative to the outer periphery of the housing 1. The folded edge 201 can abut against the outer wall of the opening 102 to form a seal. A waterproof groove 202 is formed between the folded edge 201 and the inner wall of the housing 1. A waterproof adhesive strip is embedded in the waterproof groove 202, and the waterproof adhesive strip abuts against the waterproof folded edge 103 to form a seal. To further enhance the waterproof performance of the electrical box for the upper controller 4, the door 2 is provided with a folded edge 201 facing inward relative to the outer periphery of the housing 1. When the door 2 is closed, the folded edge 201 can tightly abut against the outer wall of the opening 102 of the housing 1, thereby forming a preliminary sealing layer. Furthermore, a waterproof groove 202 is cleverly formed between the folded edge 201 and the inner wall of the box body 1. A waterproof rubber strip is embedded in this waterproof groove 202. This waterproof rubber strip not only has excellent elasticity and sealing properties, but also closely fits the waterproof folded edge 103 at the opening 102 of the box body 1. The two work together to form a double sealing barrier, effectively preventing external impurities such as moisture and dust from invading the interior of the electrical box, ensuring the safe and stable operation of the electrical components. This design not only improves the waterproof performance of the electrical box, but also extends its service life, providing a strong guarantee for the reliable control of vehicle-mounted equipment.

[0041] In addition, at least two drainage holes 203 are provided at the bottom of the door 2. In order to cope with moisture that may penetrate into the electrical box in extreme weather or unexpected situations, at least two drainage holes 203 are specially provided at the bottom of the door 2. These drainage holes 203 can effectively collect and drain moisture accumulated at the bottom of the door 2 or inside the electrical box, preventing moisture from being retained for a long time and causing damage to electrical components. At the same time, the number and distribution of the drainage holes 203 can be adjusted according to actual conditions to ensure drainage efficiency while avoiding adverse effects on the overall sealing performance of the electrical box. Through such a design, the electrical box has increased its ability to respond to unexpected situations while maintaining good waterproof performance, further improving its reliability and durability.

[0042] Generally speaking, in order to enhance the interface diversity and practicality of the electrical box of the upper-mounted controller 4, at least two aviation sockets 6 and cable connectors 7 are provided at the bottom of the box body 1. These two aviation sockets 6 and cable connectors 7 are arranged in sequence at intervals at the bottom of the box body 1, which not only ensures the relative independence between the interfaces, but also facilitates connection with external devices or power supplies. The aviation socket 6 is widely used in electrical systems that require high reliability and fast connection due to its sturdy structure, easy plugging and unplugging, and reliable connection. The provision of the cable connector 7 further expands the scope of application of the electrical box, allowing different types of cables to be easily connected to the electrical box. Such a design not only improves the interface flexibility of the electrical box, but also meets the connection requirements of different vehicles and equipment, providing a more convenient and efficient solution for the electrical control of vehicle upper-mounted equipment.

[0043] To further enhance the design of the electrical box housing the upper body controller 4, a wire hole 104 is specifically designed at the bottom of the housing 1. The design of this wire hole 104 fully considers the cable connection requirements between the electrical components within the electrical box and external devices. Through wire hole 104, the cables within the electrical box can be led out in an orderly and safe manner to establish electrical connections with external devices. The position and size of wire hole 104 are designed to ensure smooth cable passage while avoiding adverse effects on the sealing performance and overall structure of the electrical box. This design not only improves the ease of use of the electrical box, but also ensures the reliability and safety of the electrical connections, providing a strong guarantee for the normal operation of the vehicle's upper body equipment.

[0044] Furthermore, the door 2 is provided with a door lock 204 that can be locked with the housing 1. The door lock 204 can closely cooperate with corresponding components on the housing 1 to achieve the locking function of the door 2. When the door 2 is closed, the operator can use the door lock 204 to securely lock the door 2 to the housing 1, preventing unauthorized personnel from opening the electrical box and thus protecting the internal electrical components from damage or theft. Furthermore, when maintenance and inspection of the internal components of the installation cavity 101 are required, the door 2 can be opened using the door lock 204 to perform the corresponding operation, which is highly practical.

[0045] In some embodiments, to further enhance the integration and functionality of the electrical box of the upper-mounted controller 4, a relay 8 and a power converter may be installed on the base plate 3 as needed. The relay 8, a commonly used electrical control component, enables automatic circuit switching and remote control in electrical control systems. Installing the relay 8 on the base plate 3 facilitates connection with the upper-mounted controller 4 and other electrical components, enabling complex control logic and circuit switching functions. This not only simplifies the wiring of the electrical system but also improves control flexibility and reliability. The power converter is used to convert one form of electrical energy into another to meet the power supply requirements of different electrical components. Installing the power converter in the electrical box ensures that the upper-mounted controller 4 and other electrical components receive a stable and appropriate power supply, ensuring their proper operation. Furthermore, the integrated design of the power converter helps reduce redundant components within the electrical box and improves space utilization. Overall, installing the relay 8 and power converter on the base plate 3 further enhances the integration and functionality of the electrical box of the upper-mounted controller 4, making it more adaptable to the complex and ever-changing control requirements of vehicle upper-mounted equipment.

[0046] It's worth noting that the current upper-mounted controller 4 fails to monitor load current and offers no protection against short circuits, overloads, or overtemperatures. It blows a fuse directly after a short circuit and cannot self-reset. It lacks a CAN interface and cannot communicate with the vehicle's CAN bus to obtain engine or motor speed and output power. The power boost obtained during power take-off (PTO) operation is automatically transferred via the PTO signal line, with no feedback. Furthermore, the output and input pins of the PLC controller 4 are separate, and the high and low signal levels of the input pins are generally fixed and non-configurable. This makes it difficult to use the same controller 4 for vehicles with different output and input requirements. The vibration and power supply interference resistance of the PLC controller 4 do not meet vehicle test standards. Therefore, the controller 4 described in this application can have some channels configured as output or input, and the output driver can directly drive high-current loads. It can monitor the output current in real time and shut down the output in the event of overload, short circuit, or overtemperature. The fault is indicated by an indicator light on the controller 4 housing, and a fault status message is sent via the CAN bus, making it easy to quickly locate the fault. Once the fault is resolved, the controller 4 automatically resumes normal output. Input pin signals can be configured via software to detect high or low levels without modifying the hardware. The body controller 4 has indicator lights on its housing, corresponding to the input and output channels, indicating input and output status and fault conditions (they light up during normal operation and flash when a fault occurs).

[0047] The power take-off of the upper body controller 4 can be controlled through the CAN bus or the PTO signal line to increase the output power of the engine or motor. At the same time, the current state is obtained through the CAN bus to form a closed-loop feedback control to avoid unstable action caused by insufficient or excessive power of the upper body action.

[0048] The upper body controller 4 can also communicate with the CAN switch control panel via the CAN bus, and perform corresponding output actions according to the key operations on the key panel, thereby reducing the situation where there are too many hard-wired connections when there are many traditional switches, and saving wiring harnesses.

[0049] To sum up, by installing the electrical box of the controller 4 on the upper body, double waterproof and dustproof protection is achieved; the adjustment of the mounting holes on the bottom plate 3 can flexibly adapt to the increase or decrease of internal components without changing the installation dimensions of the box 1 and the vehicle; by using on-board connectors, there is no need to use terminal blocks to connect wires one by one when installing the vehicle; the controller 4 has indicator lights to indicate the working status of the input and output channels, and can also send fault information through the CAN bus; the output channel can directly drive a large current load, can monitor the load current in real time, and has overload, short circuit, overtemperature and other protections; some channels can be configured as output or input channels for multiplexing, avoiding the need to increase the model of the controller 4 when different models require different numbers of input and output channels, and the number of input and output channels can be adjusted through software configuration; the input channel can be configured by software to be high level or low level valid. When different models need to adjust the port definition and effective signal level, there is no need to update the wiring harness, only modify the software configuration; it can communicate with the CAN key switch panel to reduce the number of wiring harnesses for key signals.

[0050] In addition, the operator 5 includes an operation box, on which are provided a power button, a run button, an emergency stop button, a lift button, a feeding cover button, a remote control indicator button, an alarm indicator light, a work light button, and two spare buttons. When using the operator 5, the operation of the relevant control devices on the vehicle can be flexibly and reasonably controlled by coordinating the use of each button.
