Description

Technical Field

[0001] The utility model relates to the technical field of electrical controllers, in particular to a central controller. Background Art

[0002] The center console of the vehicle includes the front power distribution box and the rear power distribution box. However, the front power distribution box cannot be installed with a high-power power switch and can only be used as the front power distribution box. The rear power distribution box has a large size due to the addition of components and is not suitable for use as a front power distribution box. In addition, the connection of the nut on the output copper bar may become loose, which may reduce the sealing effect. Utility Model Content

[0003] The utility model provides a central controller to solve the technical problems that the existing central controller is not compatible with the front and rear power distribution boxes and the sealing effect is easily reduced.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An output chip fuse is provided on one side of the circuit board, and the output chip fuse is connected to an output bolt through an output copper bar. The middle part of the circuit board is a device installation part for installing one or more of a fuse, a relay, and a power switch. An input pin is provided on the other side of the circuit board;

[0007] The upper surface of the middle shell is provided with a fuse relay multiplexing jack and a window corresponding to the power switch. The device installation part of the circuit board is compatible with relays and fuses. The design of each relay can be compatible with the use of fuses. When the high-power power switch is not in use, it can be replaced with a low-power fuse relay, so that the controller can be compatible with the front and rear distribution boxes.

[0008] Furthermore, a reserved plug-in fuse position is provided on the circuit board below the output chip fuse, and when the high-power chip fuse is not in use, it can be replaced with a low-power plug-in fuse.

[0009] Furthermore, a groove is provided on the output copper busbar, a wiring board is slidably connected to the output bolt, and a convex block corresponding to the groove is provided at the bottom of the wiring board.

[0010] Furthermore, an annular groove is provided on the side of the wiring board, a clamping board sealing ring is provided in the annular groove, and a supporting column is provided below the output bolt.

[0011] Further, a flip cover covering the output bolt is provided at the front end of the upper cover, and a dust-proof curtain is provided at the front end of the flip cover.

[0012] Further, the upper cover and the middle shell are fixedly connected by screws or buckles. When sealing and waterproofing are required, a sealing ring and screws can be used for fixation; when there is no waterproof requirement, two buckles are respectively designed on both sides, which can be directly buckled to prevent detachment, saving both screws and the operation of manually driving screws.

[0013] Further, an upper sealing ring is provided between the upper cover and the middle shell, and a lower sealing ring is provided between the middle shell and the bottom cover.

[0015] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0016] 1. In the present utility model, the design of each large and small relay can be compatible with the use of fuses. When the high-power power switch is not in use, it can be replaced with a small-power fuse relay, compatible with the functions of the front and rear distribution boxes.

[0017] 2. The connection between the lead-out copper bar and the wiring terminal of the present utility model is anti-rotation, using a snap-on type. The sealing between the wiring terminal and the main body shell is achieved by opening a groove around the middle of the wiring terminal, and the O-ring is sleeved in the groove of the wiring terminal.

Detailed implementation mode

[0024] The following combines the accompanying drawings and embodiments to illustrate the detailed implementation mode of the present invention. However, the following embodiments are only used to elaborate on the present invention in detail and do not limit the scope of the present invention in any way.

[0025] Embodiment 1: A central controller, see Figure 1 , including bottom cover 1, middle shell 2, circuit board 3, and upper cover 4. The bottom cover 1 and the middle shell 2 are fixedly connected. The circuit board 3 is fixed to the inner top surface of the middle shell 2 by screws, and the upper cover 4 and the middle shell 2 are fixedly connected.

[0026] On one side of the circuit board 3, there is a row of output chip fuses 5. Each output chip fuse 5 is connected to two columns and connected to the output bolt 52 outside the circuit board 3 through the output copper bar 51. There is a groove on the side of the output copper bar 51. A wiring terminal 53 is slidably connected to the output bolt 52, and a bump 54 corresponding to the groove is provided at the bottom of the wiring terminal 53. There is an annular groove on the side of the wiring terminal 53, and a clamping table sealing ring 55 is provided in the annular groove. A support column 56 is provided below the output bolt 52 to make the output bolt 52 and the circuit board at the same height to prevent the output bolt 52 from being pressed and collapsed. A reserved plug-in fuse position 57 is provided on the circuit board 3 below the output chip fuse 5. When the high-power chip fuse is not used, it can be replaced with a low-power plug-in fuse.

[0027] The middle part of the circuit board 3 is a device installation part 31, which has a plurality of device insertion cards for inserting and installing one or more of fuses, relays, and power switches. Input pins 32 are provided on the other side of the circuit board. On the upper surface of the middle shell 2, there are fuse-relay multiplexing jacks 21 and a window 22 corresponding to the power switch. The device installation part of the circuit board 3 can be compatible with relays and fuses, and each relay design can be compatible with the use of fuses. For example, a module has 6 device insertion cards, which correspond to the fuse-relay multiplexing jacks 21. Either a 6-pin relay or 3 2-pin fuses can be inserted, so that the middle shell 2 can still be applicable when the function of the circuit board 3 is replaced. When the high-power power switch is not in use, it can be replaced with a low-power fuse-relay. At this time, installing the fuse-relay multiplexing jacks 21 on the window 22 can achieve this, enabling the controller to be compatible with the front and rear distribution boxes. The input pins 32 include multiple rows of pins arranged in a staggered manner, and an anti-misinsertion plug 33 is connected thereto. An anti-misinsertion groove 34 is provided on the insertion surface of the anti-misinsertion plug 33.

[0028] At the front end of the upper cover 4, there is a flip cover 41 covering the output bolt, and a dust-proof curtain 42 is provided at the front end of the flip cover 41. The upper cover 4 and the middle shell 2 are fixedly connected by screws at the four corners or the side buckles 43. When sealing and waterproofing are required, a sealing ring and screws can be used for fixation; when there is no waterproof requirement, two buckles are designed on both sides respectively, which can be directly buckled to prevent falling off, saving both screws and the operation of manually screwing in the screws. An upper sealing ring 44 is provided between the upper cover 4 and the middle shell 2, and a lower sealing ring 11 is provided between the middle shell 2 and the bottom cover 1.

[0029] The above has described the present utility model in detail with reference to the accompanying drawings and embodiments. However, those skilled in the art can understand that without departing from the purpose of the present utility model, various specific parameters in the above embodiments can be changed to form multiple specific embodiments, which are all within the common change range of the present utility model and will not be elaborated one by one here.
