[0026] like Figure 1 As shown in the figure, an embodiment of the present invention provides an intelligent controller for forklifts, comprising a housing 1, a circuit board 2, a connector 4, a female connector bracket 6, a screw 7, and a first sealing ring 3.

[0027] The outer shell 1 is a hollow structure used to house the internal components.

[0028] Circuit board 2 is located inside housing 1 and is used to implement the control logic for industrial vehicles.

[0029] Connector 4 is electrically connected to circuit board 2 to enable signal transmission between external circuits and circuit board 2.

[0030] The female connector bracket 6 is used to support and fix the connector 4.

[0031] Screw 7 is used to fasten the female connector bracket 6 to the housing 1.

[0032] The first sealing ring 3 is located between the outer shell 1 and the connector 4 to achieve a seal at the connection between the outer shell 1 and the connector 4.

[0033] This embodiment of the invention combines a housing 1, a circuit board 2, a connector 4, a female connector bracket 6, screws 7, and a first sealing ring 3 to form the overall controller structure. Each component has a clear function and fits tightly together. The housing 1, as a hollow structure, provides installation space for internal components; the connector 4 is electrically connected to the circuit board 2 to achieve signal transmission, ensuring the implementation of control logic; the female connector bracket 6, together with the screws 7, fixes the connector 4, making the connection simple and reliable, reducing assembly difficulty; the first sealing ring 3, located between the housing 1 and the connector 4, effectively prevents external dust, moisture, etc., from entering the controller, avoiding impact on components such as the circuit board 2, and improving sealing reliability. The overall structural design is simplified, reducing redundant components, thereby reducing production and assembly costs.

[0034] The present invention also includes a second sealing ring 5, which is disposed between the connector 4 and the female bracket 6 to achieve sealing at the connection between the connector 4 and the female bracket 6.

[0035] The second sealing ring 5 forms an effective seal at the connection between the connector 4 and the female bracket 6, and together with the first sealing ring 3, forms a multi-seal structure, further enhancing the overall sealing performance of the controller, reducing the possibility of impurities in the external environment entering the interior through the connection gap between the connector 4 and the female bracket 6, improving the working stability of the controller in complex industrial environments, and extending its service life.

[0036] In this embodiment of the utility model, the connector 4 is provided with a plug interface that is adapted to the external plug. The shape of the plug interface matches the shape of the external plug, which can ensure that the external plug and the connector 4 are in close and stable contact when connected. This avoids problems such as poor contact, signal transmission interruption or distortion caused by interface mismatch, and ensures that the external signal is accurately input to the circuit board 2 and the control signal is effectively output to the external actuator, thereby improving the accuracy and reliability of the controller in controlling industrial vehicles.

[0037] Circuit board 2 integrates circuit modules for controlling the driving, hydraulic operation, and safety warning functions of industrial vehicles. There is no need to set up separate control components for different functions, which can reduce the number of components inside the controller, simplify the overall structure, reduce the assembly complexity and failure risk caused by the connection of multiple components, and at the same time reduce the use of materials, further reducing production costs.

[0038] The outer casing 1 is manufactured using injection molding. The inner wall of the outer casing 1 is provided with positioning bosses for positioning the circuit board 2. The injection molding of the outer casing 1 has high production efficiency and low molding difficulty, which can reduce the processing cost of the outer casing 1. The positioning bosses on the inner wall of the outer casing 1 can accurately position the circuit board 2, which makes it easy for the circuit board 2 to be quickly and accurately installed into the outer casing 1, reducing the adjustment time during the assembly process, improving assembly efficiency, and reducing labor costs.

[0039] The female connector bracket 6 is made of plastic. Both the female connector bracket 6 and the outer shell 1 are provided with threaded holes that mate with screws 7. The female connector bracket 6 has lower cost and lighter weight, which can reduce the cost of component procurement. The screws 7 can be directly passed through the threaded holes to firmly connect the female connector bracket 6 and the outer shell 1. The connection method is simple and stable, avoiding the use of additional connecting parts, simplifying the assembly process, improving assembly efficiency, and ensuring the reliability of the connection structure.

[0040] During assembly, the first sealing ring 3 is placed at the corresponding sealing position of the outer shell 1; the circuit board 2 is positioned by the positioning boss on the inner wall of the outer shell 1, and then placed inside the outer shell 1; the second sealing ring 5 is fitted onto the corresponding position of the connector 4, and then the connector 4 and the female connector bracket 6 are assembled; the female connector bracket 6 with the connector 4 is fastened to the outer shell 1 by screws 7, completing the overall assembly of the controller. In use, the external plug is connected to the connector 4's interface to achieve signal input and output, thereby controlling the industrial vehicle through the circuit board 2.

[0041] The working principle of this utility model embodiment is as follows:

[0042] The integrated circuit module on circuit board 2 receives external signals (such as operation command signals) transmitted through connector 4. After internal logic operations, it outputs control signals for controlling the movement of industrial vehicles, hydraulic operation, safety warnings, and other actions. These control signals are then transmitted to external actuators via connector 4. Simultaneously, the first sealing ring 3 seals the connection between the outer shell 1 and connector 4, and the second sealing ring 5 seals the connection between connector 4 and female bracket 6. Together, they prevent external dust and moisture from entering the controller, ensuring the stable operation of components such as circuit board 2.

[0043] This utility model embodiment achieves multiple technical advantages through the coordinated cooperation of the outer shell 1, circuit board 2, connector 4, female connector bracket 6, screw 7, first sealing ring 3, and second sealing ring 5:

[0044] 1. In terms of structure and cost: Each component has a clear division of labor and works closely together, reducing redundant components, simplifying the overall structure, and reducing the cost of production and assembly; the circuit board 2 integrates a multi-functional circuit module, eliminating the need for multiple additional control components, further simplifying the system structure, reducing material usage, and lowering costs.

[0045] 2. Sealing performance: The first sealing ring 3 and the second sealing ring 5 form a multi-layer sealing structure, which effectively prevents external dust and moisture from entering, improves the working stability of the controller in complex industrial environments, and extends its service life.

[0046] 3. Assembly efficiency: The positioning boss on the inner wall of the outer shell 1 facilitates the quick and accurate installation of the circuit board 2, reducing assembly and adjustment time; the female connector bracket 6 is directly connected to the outer shell 1 through the screw 7 and the threaded hole, without the need for additional connecting parts, simplifying the assembly process and improving assembly efficiency.

[0047] 4. Control reliability: The interface of connector 4 is compatible with the shape of the external plug, ensuring stable signal transmission and avoiding problems such as poor contact and signal loss, thus ensuring the accuracy and reliability of the controller in controlling industrial vehicles.

[0048] This utility model provides an intelligent controller for forklifts that effectively reduces production, assembly, and maintenance costs while meeting the control function requirements of industrial vehicles, and simultaneously improves sealing performance and operational reliability.
