DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0033] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, "including" is not limited to the listed structures, but may optionally include structures not listed, or may optionally include other components inherent to those structures.

[0034] The present application discloses a diesel engine controller integrated with a T-BOX, which realizes the integrated configuration of the diesel engine controller and the T-BOX. Detailed descriptions are given below.

[0035] Figure 1 – Figure 6 FIG. 1 shows a diesel engine controller integrated with a T-BOX according to an embodiment of the present application. Figure 1 – Figure 6 As shown, the T-BOX integrated diesel engine controller includes a controller housing 1 and a T-BOX 10 integrated on the controller housing 1 .

[0036] Specifically, such as Figure 4 and Figure 5As shown, the controller housing 1 is the main housing structure of the diesel engine controller. A cavity 2 is provided on the first inner surface of the controller housing 1, which is used to secure the diesel engine controller's electronic control components, electrical control components, and electrical power components. Corresponding to the first inner surface of the controller housing 1, the cavity 2 extends in a first direction away from the first inner surface. A raised structure 3 is formed on the first outer surface of the controller housing 1, opposite the first inner surface. The raised structure 3 comprises a first raised portion 4, a second raised portion 5, and a third raised portion 6, each integrally connected to the first outer surface of the controller housing 1. The first raised portion 4 extends in a second direction on the first outer surface of the controller housing 1 and is located at a first edge of the controller housing 1. The second raised portion 5 extends in a third direction on the first outer surface of the controller housing 1 and is located in the middle of the first outer surface of the controller housing 1. The first raised portion 4 and the second raised portion 5 are perpendicularly connected to each other, and the third raised portion 6 is provided at the corner connecting the first and second raised portions 4 and 5. Furthermore, in some specific embodiments, a mounting hole 24 is provided at one end of the third protrusion 6 away from the second protrusion 5, which is used to achieve a fixed connection between the internal components of the controller housing 1 and the controller housing 1 by providing a connecting piece (not shown in the figure) in the mounting hole 24.

[0037] In the embodiments of this application, Figure 4 and Figure 5 As shown, a terminal fixing frame 7 is provided on the first outer surface of the controller housing 1 to define the installation position of the T-BOX 10 on the controller housing 1. Specifically, the terminal fixing frame 7 includes a first frame portion 8 and a second frame portion 9, which are integrally arranged. On the first outer surface of the controller housing 1, the first frame portion 8 extends in the second direction and is located at the second edge of the controller housing 1. The second frame portion 9 extends in the third direction and is located at the junction of the second raised portion 5 and the third raised portion 6. Together, the first frame portion 8 and the second frame portion 9 form a T-shaped frame structure, which is positioned opposite the raised portion 3. This fully utilizes the overall structure of the controller housing 1, reduces the overall controller footprint, and minimizes the size of the diesel engine controller integrated with the T-BOX. In some specific embodiments, the first side of the second raised portion 5 is aligned with the first side of the first frame portion 8 in the third direction, and the first side of the third raised portion 6 is aligned with the first side of the second frame portion 9 in the third direction, further maximizing the utilization of the controller housing 1.

[0038] It should be noted that, in the embodiments of the present application, Figure 4 and Figure 5As shown, the first inner surface and the first outer surface are the inner and outer sides of one side surface of the controller housing 1, the first edge and the second edge are two edges arranged opposite to each other on the first outer surface, the first side of the second protrusion 5 is the side of the second protrusion 5 away from the third protrusion 6 in the second direction, the first side of the first frame portion 8 is the side of the first frame portion 8 close to the first side of the second protrusion 5 in the second direction, the first side of the third protrusion 6 is the side of the third protrusion 6 away from the second protrusion 5 in the second direction, and the first side of the second frame portion 9 is the side of the second frame portion 9 close to the first side of the third protrusion 6 in the second direction.

[0039] In addition, in the embodiment of the present application, the first direction is a direction perpendicular to the first inner surface of the controller housing, the second direction is a direction parallel to the first edge of the controller housing, and the third direction is a direction perpendicular to the first edge of the controller housing. The first direction, the second direction, and the third direction are mutually perpendicular. However, it should be noted that "perpendicular" in this application is not absolutely perpendicular and can be 90°±5°. "Parallel" in this application is also not absolutely parallel and can be 180°±5°.

[0040] like Figure 1 – Figure 3 As shown, T-BOX 10 includes a terminal housing 11 and a PCBA board 12 disposed within terminal housing 11. Terminal housing 11 is a T-shaped cavity structure with one end open. The shape and size of terminal housing 11 match those of terminal mounting frame 7. By fixing the open end of terminal housing 11 to terminal mounting frame 7, T-BOX 10 is integrated with controller housing 1. Furthermore, in the first direction, the installation height of terminal housing 11 within controller housing 1 is the same as the height of protruding structure 3, making the diesel engine controller with integrated T-BOX more aesthetically pleasing and taking up less space.

[0041] During the specific implementation process, a groove can be provided on the end face of the terminal fixing frame away from the controller housing, and a protrusion can be provided on the open end face of the terminal housing. The shape and size of the protrusion match the shape and size of the groove, so that the protrusion is clamped in the groove to position and connect the terminal housing and the terminal fixing frame, further ensuring that the two can be quickly positioned and installed, and the connection is more stable.

[0042] In some embodiments, as Figure 1 – Figure 6As shown, the diesel engine controller with integrated T-BOX is also provided with a positioning structure. In detail, in some specific implementation processes, the positioning structure includes a first positioning hole 13 and a first positioning column 14. Six first positioning holes 13 are provided on the first outer surface of the controller housing 1, each of which is located in the terminal fixing frame 7, and each of the first positioning holes 13 passes through the inner and outer sides of the controller housing 1. Two first positioning holes 13 are respectively provided at both ends of the first frame part 8 and at one end of the second frame part 9 away from the first frame part 8, and the distance between the first positioning hole 13 located at one end of the first side of the first frame part 8 and the first side of the first frame part 8 is smaller than the distance between the first positioning hole 13 located at one end of the second side of the first frame part 8 and the second side of the first frame part 8, wherein the second side of the first frame part 8 is the side of the first frame part 8 away from the first side of the second protrusion 5 in the second direction. Correspondingly, six first positioning columns 14 are provided in the terminal housing 11, and the setting position of each first positioning column 14 corresponds one-to-one to the setting position of the six first positioning holes 13, and the shape and size of the first positioning column 14 match the shape and size of the first positioning hole 13, so that the first positioning column 14 is inserted into the first positioning hole 13 to achieve the preliminary positioning and fixation between the terminal housing 11 and the controller housing 1. Furthermore, the first positioning column 14 that passes through the accommodating cavity 2 is fixed to the controller housing 1 by ultrasonic welding, thereby achieving a fixed connection between the T-BOX10 and the controller housing 1. The fixing is in the form of ultrasonic welding, which has good efficiency, economy, environmental protection, reliability and applicability, and has a high degree of automation, good welding quality and high connection strength. Of course, the T-BOX10 and the controller housing 1 can also be fixed by bolt connection, which is easier to install.

[0043] In some specific implementation processes, such as Figure 1 – Figure 6 As shown, the positioning structure also includes a second positioning post 15 and a second positioning hole 16. A plurality of second positioning posts 15 are provided within the terminal housing 11, and correspondingly, a plurality of second positioning holes 16 are provided on the PCBA board 12. The positions of the plurality of second positioning posts 15 correspond one-to-one with the positions of the plurality of second positioning holes 16, and the shape and size of the second positioning posts 15 are identical to those of the second positioning holes 16. Thus, by inserting the second positioning posts 15 into the second positioning holes 16, the PCBA board 12 is initially positioned and installed within the terminal housing 11. The PCBA board 12 and the second positioning posts 15 can be fixed by welding or bolting, which is not limited in this embodiment.

[0044] Further, such as Figure 1 – Figure 3As shown, in this embodiment, there are five second positioning posts 15. Two second positioning posts 15 are positioned between two first positioning posts 14 corresponding to the two first positioning holes 13 located at one end of the first side of the first frame portion 8; one second positioning post 15 is positioned between two first positioning posts 14 corresponding to the two first positioning holes 13 located at one end of the second side of the first frame portion 8; and two second positioning posts 15 are positioned between two first positioning posts 14 corresponding to the two first positioning holes 13 located at the end of the second frame portion 9 away from the first frame portion 8. The first and second positioning posts 14, 15 are arranged sequentially in the third direction away from the side surface of the terminal housing 11. Thus, by varying the number and position of the second positioning posts 15 at the three ends, the system provides a certain degree of error-proofing for installation, facilitates quick installation, and achieves high accuracy.

[0045] In the embodiments of this application, Figure 2 As shown, the first positioning column 14 includes an integrated first large cylindrical portion 17 and a first small cylindrical portion 18. The first large cylindrical portion 17 and the first small cylindrical portion 18 are arranged in sequence in a direction away from the terminal housing 11. The first large cylindrical portion 17 and the first small cylindrical portion 18 limit the terminal housing 11 and the controller housing 1 in the first direction through the arrangement of the first large cylindrical portion 17 and the first small cylindrical portion 18. Similarly, the second positioning column 15 includes an integrated second large cylindrical portion 19 and a second small cylindrical portion 20. The second large cylindrical portion 19 and the second small cylindrical portion 20 are arranged in sequence in a direction away from the terminal housing 11. The second large cylindrical portion 19 and the second small cylindrical portion 20 limit the PCBA board 12 and the terminal housing 11 in the first direction through the second large cylindrical portion 19 and the second small cylindrical portion 20. In addition, the height of the second positioning column 15 is less than the height of the first large cylindrical portion 17 to ensure that the PCBA board 12 does not interfere with the controller housing 1.

[0046] In other specific implementation processes, such as Figure 2 As shown, a connecting reinforcement 21 is further provided between the first large cylindrical portion 17 and the terminal housing 11, and / or a connecting reinforcement 21 is provided between the second large cylindrical portion 19 and the terminal housing 11, and / or a connecting reinforcement 21 is provided between the first large cylindrical portion 17 and the second large cylindrical portion 19. Furthermore, a plurality of reinforcing ribs 22 are provided at the vertical connection angles of the terminal housing 11. By providing the reinforcement 21 and the reinforcing ribs 22, the structural stability of the terminal housing 11 is enhanced, thereby ensuring the installation stability of the T-BOX 10. Furthermore, the terminal housing 11 can be made of PA66 (polyamide 66) + GF30 (30% glass fiber reinforcement), which has high strength, high rigidity, good high temperature resistance and corrosion resistance, and good dimensional stability and is not easy to deform.

[0047] In addition, if Figure 4 and Figure 6As shown, a plurality of heat dissipation fins 23 evenly distributed along the second direction are further provided on the first outer surface of the controller housing 1. Specifically, the plurality of heat dissipation fins 23 are located on one side of the first side edge of the second protrusion 5, and / or the plurality of heat dissipation fins 23 are located on one side of the first side edge of the third protrusion 6. Thus, the provision of the heat dissipation fins 23 achieves heat dissipation of the internal components of the controller housing 1, ensures a relatively stable working environment for the internal components, and increases the service life of the controller.

[0048] In summary, the present application discloses a diesel engine controller with an integrated T-BOX, which realizes the integrated setting of the diesel engine controller and the T-BOX. The T-BOX is electrically connected to the diesel engine controller, thereby realizing the needs of remote monitoring and management of the diesel engine controller. Moreover, through the setting of the T-shaped frame structure and the setting of the raised structure of the accommodating cavity on the first outer surface, the controller housing is maximized, making the overall structure of the controller smaller.
