[0037] In order to make the objects, technical solutions and advantages of the application clearer, the technical solutions in the application will be described clearly and completely below in combination with the drawings in the application. Obviously, the described embodiments are some embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the application.

[0038] In the related art, the control switches of different hydraulic circuits are distributed at different positions in the cab. For example, the control switches can be distributed on the left handle, the right handle and the key panel in the cab. The work machine usually installs one tool at a time, and after installing the tool, the operator needs to manipulate the control switch at the corresponding position to control the hydraulic circuit corresponding to the tool.

[0039] As described above, after replacing the implement, the operator needs to adapt to the position of the corresponding control switch, but due to the operation habit of the operator and other reasons, after replacing the implement, the operator is prone to inconvenient and unskilled operation of the control switch, which affects the work efficiency.

[0040] In order to solve or improve the technical problem in the prior art that the operator needs to adapt to the position of the corresponding control switch after replacing the implement, and achieve the effect of improving the convenience and proficiency of the operator in operating the control switch after replacing the implement, the present application provides a hydraulic circuit control system, a hydraulic circuit control method and a working machine.

[0041] Reference will be made below to Figures 1-2 The hydraulic circuit control system provided in the embodiments of the present application is described.

[0042] Specifically, the hydraulic circuit control system is used to control the hydraulic circuit 4 of the implement. It should be noted that the number of hydraulic circuits 4 is usually multiple, and the multiple hydraulic circuits 4 are used to drive different implements to perform corresponding actions, for example, different hydraulic circuits 4 can usually be used to drive the corresponding implements to perform forward and reverse rotation actions, opening and closing actions or forward and backward actions. Of course, one hydraulic circuit 4 can also be applicable to different implements, which is not the focus of this application and will not be described again.

[0043] The hydraulic circuit 4 system includes a control valve group 1, a control switch 2 and a processing unit 3.

[0044] Among them, the number of control valve groups 1 is multiple, and the control valve groups 1 are respectively connected with the corresponding hydraulic circuits 4 to control the actions of the corresponding hydraulic circuits 4. Alternatively, one hydraulic circuit 4 can correspond to one or at least two control valve groups 1.

[0045] The control switch 2 is operated by the operator. Alternatively, the control switch 2 can be a control button, a rocker switch, a rotary switch or a control handle.

[0046] The processing unit 3 is connected with the control valve group 1 and the control switch 2, and the processing unit 3 is configured to selectively associate any one control valve group 1 with the control switch 2, and control the control valve group 1 associated with the control switch 2 to act based on the control signal of the control switch 2. Here, the association means that the corresponding control valve group 1 is bound or corresponds to the control switch 2, so that when the operator operates the control switch 2, the processing unit 3 receives the control signal of the control switch 2, and can control the corresponding control valve group 1 to act based on the control signal.

[0047] Alternatively, the processing unit 3 can be a vehicle controller of the working machine, or the processing unit 3 can also be a controller independent of the vehicle controller.

[0048] The hydraulic circuit control system provided in the embodiments of the present application is connected with the hydraulic circuit 4 of the tool through the control valve group 1 and controls the action of the hydraulic circuit 4, so as to control the tool to perform corresponding action. The processing unit 3 connected with the control valve group 1 and the control switch 2 can selectively associate any one control valve group 1 with the control switch 2, and control the control valve group 1 associated with the control switch 2 to act based on the control signal of the control switch 2.

[0049] For example, after replacing the tool, the processing unit 3 can associate the corresponding control valve group 1 of the hydraulic circuit 4 of the tool with the control switch 2, and the operator operates the control switch 2 to send a control signal to the processing unit 3, and the processing unit 3 controls the control valve group 1 associated with the control switch 2 to act based on the control signal, so as to realize the corresponding action of the tool.

[0050] In this way, the hydraulic circuit control system provided in the embodiments of the present application associates the corresponding control valve group 1 with the control switch 2 through the processing unit 3, and controls the control valve group 1 associated with the control switch 2 to act based on the control signal of the control switch 2, so that the operator can selectively control the control valve group 1 of all hydraulic circuits 4 through the control switch 2, without the need to re-adapt the position of the corresponding control switch 2 after replacing the tool, so that the operator still has high convenience and proficiency in operating the control switch 2 after replacing the tool.

[0051] In some embodiments provided by the present application, the number of control switches 2 is set to at least two.

[0052] Correspondingly, the processing unit 3 is configured to selectively associate any one control valve group 1 with the control switch 2, including:

[0053] The processing unit 3 can associate the control valve group 1 with any one control switch 2, or the processing unit 3 can associate the control valve group 1 with at least two control switches 2.

[0054] In this embodiment, by setting at least two control switches 2, at least two control switches 2 can be distributed on both sides of the driving position. For the operator who is used to using left hand or right hand, he can associate the control valve group 1 with the control switch 2 at the corresponding position according to his own habit, so as to operate the control switch 2 at a comfortable position and improve the work efficiency.

[0055] In addition, by setting at least two control switches 2 and associating the control valve group 1 with the at least two control switches 2 by the processing unit 3, for a tool with two or more degrees of freedom, at least two control switches 2 are generally required to control the corresponding degrees of freedom of the tool, for example, assuming that the tool can both displace and rotate, one control switch 2 is required to control the corresponding hydraulic circuit 4 to drive the tool to move, and another control switch 2 is required to control the corresponding hydraulic circuit 4 to drive the tool to rotate.

[0056] Meanwhile, when the action of the tool needs to be controlled by multiple control switches 2, the control switches 2 are respectively used to control the corresponding hydraulic circuit 4, so that the hydraulic circuit 4 can respectively drive the tool to perform the corresponding action. The setting position of the control switch 2 is different, and the operator can adjust the correspondence between the hydraulic circuit 4 and the control switch 2 according to his own habit, associate the hydraulic circuit 4 with the control switch 2 at the corresponding position, so as to meet the operation habit of the operator. For example, the hydraulic circuit 4 with higher operation frequency can be associated with the control switch 2 most skilled by the operator, that is, the operation frequency of the hydraulic circuit 4 is corresponding to the proficiency of the control switch 2, so as to make the operator comfortable and improve the operation efficiency.

[0057] Therefore, by associating the control valve group 1 with the at least two control switches 2 by the processing unit 3, and controlling the control valve group 1 based on the control signal of each control switch 2 by the processing unit 3, the tool can realize the corresponding action combination, so as to complete more complex work tasks.

[0058] In some embodiments provided by the present application, the hydraulic circuit control system further comprises a first handle, a second handle and a control panel. At least one of the first handle, the second handle and the control panel is provided with a control switch 2.

[0059] In the embodiment, the control switch 2 can be arranged on the first handle, the second handle and the control panel, so that the operator can associate the corresponding control valve group 1 with the control switch 2 on the first handle, the second handle or the control panel according to the operation habit, so as to make the operator more comfortable.

[0060] Further, for a working machine such as a loader or an excavator provided with a sliding walking mechanism, the first handle and the second handle can be respectively arranged as a left handle and a right handle of the working machine, so that the operator can also control the tool by the control switch 2 during the walking of the working machine, that is, the operator can more conveniently control the walking of the working machine and the action of the tool.

[0061] Optionally, the control panel can be arranged on the right side or the right front side of the driving position. Since the proportion of right-handed people is larger, arranging the control panel on the right side can meet the operation habit of more people.

[0062] Optionally, as shown in Figure 1 The number of control switches 2 is set to four. The left handle is provided with one control switch 2, the operating panel is provided with one control switch 2, and the right handle is provided with two control switches 2. The number of control valve groups 1 is set to four. It is assumed that Figure 1 The second control valve group 1 from the top is associated with the first control switch 2 from the top. After the control switch 2 sends a control signal to the processing assembly, the processing unit 3 controls the second control valve group 1 from the top to act based on the control signal. The remaining association relationships can be derived in the same way.

[0063] In some embodiments provided by the present application, the hydraulic circuit control system further comprises:

[0064] An association relationship acquisition assembly 5 connected to the processing unit 3, the association relationship acquisition assembly 5 is adapted to acquire association information of the control valve group 1 and the control switch 2.

[0065] Optionally, the association information includes the position information of the control valve group 1 and the position information of the control switch 2.

[0066] After receiving the association information, the processing unit 3 associates the corresponding control valve group 1 with the control switch 2 according to the association information. The processing unit stores the association information in the memory, and controls the control valve group 1 associated with the control switch 2 to act based on the control signal of the control switch 2 according to the association information.

[0067] In this embodiment, the operator can transmit the association information to the processing unit 3 through the association relationship acquisition assembly 5 according to his own needs, so that the processing unit 3 can associate the corresponding control valve group 1 with the control switch 2 based on the association information.

[0068] Further, the association relationship acquisition assembly 5 includes an input module connected to the processing unit 3. The input module is set to be able to receive the association information input by the operator and transmit the association information to the processing unit 3.

[0069] In this embodiment, the operator can input the association information to the processing unit 3 through the input module, so that the processing module can associate the control valve group 1 with the control switch 2 based on the association information.

[0070] In some embodiments provided by the present application, the input module includes a first input unit group and a second input unit group.

[0071] The first input unit group includes a corresponding first input unit 502 of the control switch 2. For example, the number of first input units 502 is the same as that of control switches 2 and one-to-one correspondence. The first input unit 502 is used to input the position information of the control switch 2 to the processing unit 3. Each first input unit 502 has a corresponding second input unit group.

[0072] The second input unit group comprises a second input unit 503 corresponding to the control valve group 1, and the second input unit 503 is used to input the bit position information of the control valve group 1 to the processing unit 3. For example, each second input unit group comprises a second input unit 503 corresponding to the control valve group 1 in one-to-one correspondence.

[0073] In this embodiment, it is assumed that the number of control switches 2 and the number of control valve groups 1 are both four, and the actual number of the two can be set according to actual needs. For example, when associating the control switch 2 corresponding to the first input unit 502 in the upper left corner, first, the input module is switched to the association state, then the first input unit 502 in the upper left corner is selected to send the bit position information of the control switch 2 corresponding to the first input unit 502 to the processing unit 3. Then, the corresponding second input unit 503 is selected from the second input unit group corresponding to the first input unit 502 in the upper left corner to send the bit position information of the control switch 2 corresponding to the second input unit 503 to the processing unit 3. Finally, the association is completed. Figure 2

[0074] In this way, by setting the corresponding second input unit group for each first input unit 502, the operator can clearly determine the correspondence between the control switch 2 and the control valve group 1.

[0075] Alternatively, a separate state switching unit can be provided to control the input module to switch to the association state. Specifically, by selecting the state switching unit, the state switching unit sends a level signal to the processing unit 3, and the processing unit 3 controls the input module to switch to the association state after receiving the level signal. In the association state, the first input unit 502 and the second input unit 503 can send the corresponding bit position information to the processing unit 3. After the input is completed, the state switching unit is selected again, and the processing unit 3 associates the control valve group 1 and the control switch 2 based on the bit position information transmitted by the first input unit 502 and the second input unit 503 after receiving the signal of the state switching unit again.

[0076] ​Of course, switching the input module to the associated state is not limited to the above-mentioned form of the state switching unit, for example, the input module can be switched to the associated state by the first input unit 502 to be associated. Specifically, after the first input unit 502 sends the corresponding bit information to the processing unit 3, the processing unit 3 receives the bit information sent by the first input unit 502, and controls the input module to switch to the associated state, at this time the corresponding second input unit 503 can be directly selected. After the input is completed, the first input unit 502 to be associated is selected again, and after the processing unit 3 receives the signal of the first input unit 502, the control valve group 1 and the control switch 2 are associated based on the bit information transmitted by the first input unit 502 and the second input unit 503. In this way, the operation is faster and more convenient.

[0077] In some embodiments provided by the application, the input module includes a touch screen or a key panel connected with the processing unit 3.

[0078] The touch screen or the key panel is configured to receive the association information input by the operator and transmit the association information to the processing unit 3.

[0079] In this embodiment, the operator can send the association information to the processing unit 3 by operating the touch screen or the key panel.

[0080] Optionally, corresponding to the touch screen, the first processing unit 3, the second processing unit 3 or the state switching unit described above can be set as a corresponding clickable area, a touchable area or a virtual key on the touch screen. Corresponding to the key panel, the first processing unit 3, the second processing unit 3 or the state switching unit described above can be set as a corresponding physical key on the key panel.

[0081] In some embodiments provided by the application, the association relationship obtaining component includes a display device 501 connected with the processing unit 3, and the display device 501 is configured to display the association information. In this way, the operator can confirm the current association information based on the display device 501. The display device can be a display screen or a display instrument.

[0082] The application also provides a hydraulic circuit control method. The hydraulic circuit control method is used to associate the corresponding control valve group 1 with the control switch 2. The implementation subject of the hydraulic circuit control method can be the processing unit 3, which can be a vehicle controller or a controller independent of the vehicle controller. The hydraulic circuit control method can be mutually referenced, learned and combined with the above-mentioned hydraulic circuit control system.

[0083] The hydraulic circuit control method includes:

[0084] First, receive the bit information of the control valve group 1 to be associated.

[0085] Optionally, the operator can transmit the rank information of the control valve group 1 to the processing unit 3 through the association relationship obtaining component 5.

[0086] Secondly, the control valve group 1 corresponding to the rank information of the control valve group 1 is associated with the control switch 2, so as to control the control valve group 1 corresponding to the rank information of the control valve group 1 to act based on the control instruction of the control switch 2.

[0087] In this way, the hydraulic circuit control method provided in the embodiment of the present application can control the control valve group 1 associated with the control switch 2 to act based on the control signal of the control switch 2 by associating the corresponding control valve group 1 with the control switch 2, so that the operator can selectively control all the control valve groups 1 of the hydraulic circuit 4 through the control switch 2, without the need to re-adapt the position of the corresponding control switch 2 after replacing the tool, thereby making the operator still have high convenience and proficiency in operating the control switch 2 after replacing the tool.

[0088] Further, under the premise that the control switch 2 is provided as at least two, before associating the control valve group 1 corresponding to the rank information of the control valve group 1 with the control switch 2, the method further comprises:

[0089] Receiving the rank information of the control switch 2 to be associated. Optionally, the operator can transmit the rank information of the control switch 2 to the processing unit 3 through the association relationship obtaining component 5.

[0090] Correspondingly, the associating the control valve group 1 corresponding to the rank information of the control valve group 1 with the control switch 2 comprises: associating the control valve group 1 with any one of the control switch 2, or associating the control valve group 1 with at least two of the control switch 2.

[0091] In the embodiment, by providing at least two control switches 2, the at least two control switches 2 can be distributed and arranged on both sides of the driving position. For the operator who is used to using the left hand or the right hand, the operator can associate the control valve group 1 with the control switch 2 at the corresponding position according to the habit of the operator, so as to operate the control switch 2 at a comfortable position, thereby improving the work efficiency.

[0092] In addition, by providing at least two control switches 2 and associating the control valve group 1 with the at least two control switches 2, for the tool having two or more degrees of freedom, two control switches 2 are generally needed to control two degrees of freedom, for example, the tool can be displaced and rotated, one control switch 2 is needed to control the hydraulic circuit 4 to drive the tool to move, and the other control switch 2 is needed to control the hydraulic circuit 4 to drive the tool to rotate.

[0093] Thus, by associating the control valve group 1 with at least two control switches 2 and controlling the control valve group 1 based on the control signals of said each control switch 2 by the processing unit 3, the implement is enabled to achieve corresponding action combinations, thereby completing more complex work tasks.
