[0002] Small two-position oil circuit board is an important component in automobiles or other mechanical equipment, and it plays a key role in the hydraulic system. The oil circuit board is usually a carefully designed and processed board with various channels and holes distributed on it for guiding and controlling the flow of hydraulic oil. Due to the need for stable control, the design and processing of the oil circuit board require higher requirements, and the oil circuit board needs to be designed separately according to the hydraulic schematic diagram. The design and processing process is complex, and requires higher technical level and professional knowledge, which increases the cost of design and processing. At present, the oil circuit board on the market is mainly of a straight-through independent structure. The reasons for the failure of this kind of oil circuit board may include clogging of the gasoline filter, unstable oil pressure, high oil temperature, poor oil quality, component failure, external factors such as vehicle collision or severe vibration, etc. The failure of the oil circuit board will cause the engine to idle unstably, lack of power when accelerating, and even stall when driving, which seriously affects the performance and safety of the vehicle. Moreover, it cannot integrate various detection devices, and the function is relatively single. If an oil circuit distribution mechanism with simple structure, good sealing performance, independent or linkage control of two groups of oil circuits, and installation of multiple detection devices can be designed, the above problems can be solved.

[0018] As Figures 1 to 6As shown, in this embodiment, the present invention includes an oil circuit board 1. The oil circuit board 1 has a first pipeline 2 and a second pipeline 3 internally. An oil inlet 4 is provided on one side of the oil circuit board 1, and the oil inlet 4 is connected to the first pipeline 2. The first pipeline 2 and the second pipeline 3 are connected by a connecting pipe 5. A first oil outlet 6 and a second oil outlet 7 are provided on the upper surface of the oil circuit board 1. The first oil outlet 6 and the second oil outlet 7 are respectively connected to the oil outlet ends of the first pipeline 2 and the second pipeline 3. A valve module 8 is provided on the upper surface of the oil circuit board 1, and the two sets of valves of the valve module 8 respectively cooperate with the first oil outlet 6 and the second oil outlet 7. Therefore, the oil circuit board 1, through a set of oil inlets 4 and connecting pipes 5, links two independent sets of the first pipeline 2 and the second pipeline 3, reducing the need for one inlet, resulting in a more stable overall flow rate, a simpler structure, and better oil diversion effect.

[0019] like Figures 3 to 6 As shown, in this embodiment, the upper end of the oil circuit board 1 is provided with a first installation pipe 9 and a second installation pipe 10. The first installation pipe 9 and the second installation pipe 10 are respectively connected to the control ends of the first pipeline 2 and the second pipeline 3. The interface ends of the first installation pipe 9 and the second installation pipe 10 are respectively connected to an external cartridge valve and an external proportional valve. Therefore, each set of pipelines is provided with an independent installation pipe, and is independently controlled by external proportional valves and cartridge valves, making the flow velocity in the two sets of pipelines more stable.

[0020] like Figure 2 As shown, in this embodiment, an oil overflow channel 11 is provided at one end of the oil circuit board 1, and the oil overflow channel 11 is connected to the second pipeline 3. Therefore, the connection of the oil overflow channel 11 to an external oil overflow valve can prevent excessive oil pressure within the oil circuit board 1 from causing leakage.

[0021] like Figure 1 As shown in this embodiment, a measuring port 12 is provided at the end of the first pipeline 2, and the measuring port 12 is connected to an external pressure gauge. Therefore, the measuring port 12 can detect the real-time pressure of the fluid entering the pipeline.

[0022] like Figure 2 As shown, in this embodiment, the upper end of the oil circuit board 1 is provided with several reserved channels 13, which are connected to several external testing devices. Therefore, the reserved channels 13 provide connection space for various testing devices.

[0023] like Figure 2As shown, in this embodiment, a device connection port 14 is provided on one side of the oil circuit board 1, and several device connection ports 14 are connected to the corresponding reserved channels 13. Therefore, the several device connection ports 14 and the several reserved channels 13 form a linkage circuit, which can cooperate with an external testing mechanism to detect various indicators of the oil circuit board 1.

[0024] like Figure 2 As shown, in this embodiment, the valve module 8 includes a directional valve 81 and a switch oil outlet head 82. The two sets of feed ends of the directional valve 81 are respectively connected to the first oil outlet 6 and the second oil outlet 7, and the two sets of switch oil outlet heads 82 are respectively connected to the two sets of discharge ends of the directional valve 81. Therefore, the valve module 8 can achieve coordinated control of the discharge from two pipelines, enabling single-pipe or multi-pipe discharge, thereby facilitating rapid switching between various operating conditions.

[0025] The working principle of this utility model is as follows: Before the equipment is started, the oil inlet 4 is connected to the external oil supply equipment, and the valve module 8 is connected to the first oil outlet 6 and the second oil outlet 7. Then, each pipeline is connected to the corresponding external detection equipment. The external oil supply equipment is turned on, and the oil enters the first pipeline 2 from the oil inlet 4 and is connected to the second pipeline 3 through the connecting pipeline 5. By adjusting the two sets of diverting valves 82 on the diverting valve 81, the precise diversion or linkage discharge of the two sets of oil circuits can be achieved.

[0026] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
