Description

Technical Field

[0001] The present invention relates to the technical field of railway vehicle control structures, and in particular to a control mechanism and a driver controller. Background Art

[0002] The driver controller is an important control device for railway locomotives and EMUs, used to control the locomotive's direction change and speed regulation. The traction speed regulation control mechanism in the driver controller can mostly realize the vehicle's speed change and braking operations, but the traction speed regulation control mechanism in the current driver controller only has a difference in direction when operating, that is, pulling forward is traction, and pulling backward is braking.

[0003] Although this method can realize the control function, it is easy to cause misoperation. Once the traction speed control mechanism pushes in the wrong direction when braking is required, it will cause a major safety hazard to the safety of train driving.

[0004] Therefore, there is an urgent need to provide a control mechanism and a controller to solve the problems existing in the prior art to a certain extent. Summary of the invention

[0005] The object of the present invention is to provide a control mechanism and a controller, so as to optimize the structure of the controller to a certain extent, distinguish between traction and braking operations, and avoid misoperation.

[0006] A control mechanism provided by the present invention comprises a control component, an unlocking mechanism, a positioning plate and a limit block; a accommodating cavity is formed in the control component, the accommodating cavity extends along the axial direction of the control component, the unlocking mechanism is arranged in the accommodating cavity and can slide relative to the control component; the unlocking mechanism comprises a pressing component, a first elastic member and a matching block, one end of the pressing component protrudes from one end of the control component, and the other end abuts against one end of the matching block, one end of the first elastic member abuts against the bottom of the accommodating cavity, and the other end abuts against the other end of the matching block; an opening connected to the accommodating cavity is formed at a position of the control component corresponding to the matching block, the limit block is installed at a position of the positioning plate corresponding to the opening, and an extension portion is formed on the matching block, and when the first elastic member is in a natural state, the extension portion is snap-fitted to the edge of one end of the limit block.

[0007] The pressing assembly includes a button and a core shaft, one end of the core shaft is connected to the button, and the button is arranged to protrude from the end of the control assembly; the other end of the core shaft is in contact with the matching block.

[0008] Specifically, the accommodating cavity includes a connecting section and a bearing section, the diameter of the bearing section is larger than the diameter of the connecting section, the core shaft is located in the connecting section, and the matching block and the first elastic member are located in the bearing section; when the button is pressed, the end of the core shaft away from the button can enter the bearing section and abut against the matching block, pushing the matching block to compress the first elastic member.

[0009] Furthermore, the mating block also includes a main body, which is located in the bearing section, the extension portion is connected to the main body, and the extension portion is located in the opening; the size of the opening in the extension direction of the accommodating cavity is larger than the size of the extension portion in the extension direction of the accommodating cavity, and the active stroke of the extension portion in the opening is adapted to the active stroke of the button.

[0010] Furthermore, the extension portion is formed with a notch, the shape of the notch is the same as the shape of the corner of the limit block, and the corner can be embedded in the notch so that the extension portion and the limit block are snap-fitted; the depth of the notch is not greater than the movable stroke of the extension portion in the opening.

[0011] Wherein, the limiting block is fan-shaped, so that the extending portion can slide along the arc surface of the limiting block.

[0012] Specifically, the control mechanism provided by the present invention also includes a feedback component, the control component includes a control panel, a rotating shaft and a limit cam, and the feedback component includes a second elastic member and a contact member; the second elastic member is connected to the contact member so that the contact member has a tendency to move toward the limit cam; one end of the rotating shaft is connected to the control panel, the limit cam is arranged on the rotating shaft, and the contact surface between the limit cam and the contact member is arc-shaped, and a plurality of recesses are formed on the contact surface, and the plurality of recesses are arranged at intervals on the contact surface.

[0013] Furthermore, the depths and widths of the plurality of recesses are different.

[0014] Furthermore, the feedback assembly also includes a support, a positioning shaft, a mounting seat and a connecting shaft; the support and the mounting seat are both arranged on the side of the positioning plate away from the control panel, one end of the second elastic member is connected to the mounting seat, and the other end is connected to one end of the support, the other end of the support is connected to the positioning shaft, and the positioning shaft is rotatably connected to the positioning plate; the connecting shaft is arranged on the support, and the abutment is arranged on the connecting shaft and is rotatably connected to the connecting shaft.

[0015] Compared with the prior art, the control mechanism provided by the present invention has the following advantages:

[0016] The control mechanism provided by the present invention includes a control component, an unlocking mechanism, a positioning plate and a limit block; an accommodating cavity is formed in the control component, the accommodating cavity extends along the axial direction of the control component, the unlocking mechanism is arranged in the accommodating cavity and can slide relative to the control component; the unlocking mechanism includes a pressing component, a first elastic member and a matching block, one end of the pressing component protrudes from one end of the control component, and the other end abuts against one end of the matching block, one end of the first elastic member abuts against the bottom of the accommodating cavity, and the other end abuts against the other end of the matching block; an opening connected to the accommodating cavity is formed at the position of the control component corresponding to the matching block, the limit block is installed at the position of the positioning plate corresponding to the opening, and an extension portion is formed on the matching block, and the first elastic member is in a natural state, and the extension portion is clamped with one end of the limit block.

[0017] From this analysis, it can be seen that the unlocking mechanism can be accommodated by the accommodating cavity formed along the axial direction of the control component, and the unlocking mechanism in the present application includes a pressing component, a first elastic member and a matching block. Since one end of the pressing component protrudes from one end of the control component, it is convenient for the driver to operate. Accordingly, when the control component is pressed down, the matching block can be pushed to press down the first elastic member, so that the first elastic member obtains a restoring force.

[0018] Since the mating block in the present application is formed with an extension portion, and an opening connected to the accommodating cavity is formed at the position of the control component corresponding to the extension portion, a limit block is provided at the position of the positioning plate corresponding to the opening, and when the first elastic member is in a natural state, the extension portion is engaged with the limit block. Therefore, when the driver does not press the pressing component, the extension portion is engaged with the limit block under the action of the first elastic member.

[0019] Furthermore, since the extension part is engaged with the edge of one end of the limit block in the present application, when the pressing assembly is not pressed, the driver can only operate the control assembly to rotate the extension part away from the limit block. When the driver presses the pressing assembly, the pressing assembly drives the matching block to press down, so that the extension part can be separated from the end of the limit block, so that the extension part can move toward the other end of the limit block.

[0020] That is, when the pressing component is not pressed, the driver's action of pulling the control component is a braking operation, and when the pressing component is pressed, the driver's action of pulling the control component is a traction operation. Therefore, in actual operation, when the vehicle needs to change speed and tow, the driver needs to press the pressing component. If the pressing component is not pressed, the control component can only achieve braking operation, so that there is a difference between braking and traction operations, avoiding the problem of misoperation affecting vehicle driving safety.

[0021] In addition, the present invention also provides a controller, including the above-mentioned control mechanism.

[0022] The driver controller using the control mechanism provided in the present application can greatly improve the reliability of the driver controller and avoid the problem of accidental touch affecting the safety of train operation because of the difference in the operating methods of traction and braking, and the driver cannot operate the traction direction without pressing the pressing component.

[0039] like Figure 1-Figure 5 As shown, the present invention provides a control mechanism, including a control component 1, an unlocking mechanism, a positioning plate 9 and a limit block 6; a accommodating cavity 103 is formed in the control component 1, and the accommodating cavity 103 extends along the axial direction of the control component 1, and the unlocking mechanism is arranged in the accommodating cavity 103 and can slide relative to the control component 1; the unlocking mechanism includes a pressing component, a first elastic member 5 and a matching block 4, one end of the pressing component protrudes from one end of the control component 1, and the other end abuts against one end of the matching block 4, one end of the first elastic member 5 abuts against the bottom of the accommodating cavity 103, and the other end abuts against the other end of the matching block 4; an opening 1021 connected to the accommodating cavity 103 is formed at a position of the control component 1 corresponding to the matching block 4, the limit block 6 is installed at a position of the positioning plate 9 corresponding to the opening 1021, and an extension portion 401 is formed on the matching block 4, and the first elastic member 5 is in a natural state, and the extension portion 401 is snap-fitted with the edge of one end of the limit block 6.

[0040] Compared with the prior art, the control mechanism provided by the present invention has the following advantages:

[0041] The control mechanism provided by the present invention can accommodate the unlocking mechanism through the accommodating cavity 103 formed along the axial direction of the control component 1, and the unlocking mechanism in the present application includes a pressing component, a first elastic member 5 and a matching block 4. Since one end of the pressing component protrudes from one end of the control component 1, it is convenient for the driver to operate. Accordingly, when the control component 1 is pressed down, the matching block 4 can be pushed to press down the first elastic member 5, so that the first elastic member 5 obtains a restoring force.

[0042] Since the mating block 4 in the present application is formed with an extension portion 401, and the position of the control component 1 corresponding to the extension portion 401 is formed with an opening 1021 connected to the accommodating cavity 103, the position of the positioning plate 9 corresponding to the opening 1021 is provided with a limit block 6, and when the first elastic member 5 is in a natural state, the extension portion 401 is engaged with the limit block 6. Therefore, when the driver does not press the pressing component, under the action of the first elastic member 5, the extension portion 401 is engaged with the limit block 6.

[0043] Furthermore, since the extension part 401 is engaged with the edge of one end of the stop block 6 in the present application, when the pressing component is not pressed, the driver can only operate the control component 1 to rotate the extension part 401 in the direction away from the stop block 6. When the driver presses the pressing component, the pressing component drives the matching block 4 to press down, so that the extension part 401 can be separated from the end of the stop block 6, so that the extension part 401 can move toward the other end of the stop block 6.

[0044] That is, when the pressing component is not pressed, the driver's action of pulling the control component 1 is a braking operation, and when the pressing component is pressed, the driver's action of pulling the control component 1 is a traction operation. Therefore, in actual operation, when the vehicle needs to change speed and tow, the driver needs to press the pressing component. If the pressing component is not pressed, the control component 1 can only achieve the braking operation, so that there is a difference between the braking and traction operations, avoiding the problem of misoperation affecting the driving safety of the vehicle.

[0045] Alternatively, if Figure 2 As shown, the pressing assembly in the present application includes a button 2 and a core shaft 3, one end of the core shaft 3 is connected to the button 2, and the button 2 is arranged to protrude from the end of the control assembly 1; the other end of the core shaft 3 is abutted against the matching block 4.

[0046] Preferably, the control panel described below in the present application includes a handle 101 and a turntable 102, wherein the handle 101 is formed with a grip portion, and a receiving groove is formed in the end of the grip portion, and one end of the button 2 is arranged in the receiving groove, and the other end protrudes from the grip portion, and a spring is arranged in the receiving groove, which can push the button 2 to protrude from the end of the grip portion. Accordingly, one end of the spindle 3 passes through the spring and is connected to the button 2, so that when the button 2 is released, the button 2 can automatically return to its original position.

[0047] It can be understood that since the matching block 4 in the present application is arranged in the turntable 102, the core shaft 3 can transmit pressure to the matching block 4 when the button 2 is operated, so that the matching block 4 can be pressed down to achieve unlocking between the extension part 401 and the limit block 6.

[0048] Alternatively, if Figure 2 As shown, the accommodating cavity 103 in the present application includes a connecting section 1031 and a bearing section 1032, the diameter of the bearing section 1032 is larger than the diameter of the connecting section 1031, the core shaft 3 is located in the connecting section 1031, and the matching block 4 and the first elastic member 5 are located in the bearing section 1032; when the button 2 is pressed, the end of the core shaft 3 away from the button 2 can enter the bearing section 1032 and abut against the matching block 4, pushing the matching block 4 to compress the first elastic member 5.

[0049] The diameter of the matching block 4 in the present application is larger than the diameter of the core shaft 3, so that it can be stably located in the bearing section 1032. The connecting section 1031 formed can, on the one hand, achieve contact between the core shaft 3 and the matching block 4, and on the other hand, can also play a guiding role for the core shaft 3 to avoid the problem of the core shaft 3 being offset and damaged during the movement.

[0050] Alternatively, if Figure 2 As shown, the mating block 4 in the present application also includes a main body portion, the main body portion is located in the bearing section 1032, the extension portion 401 is connected to the main body portion, and the extension portion 401 is located in the opening 1021; the size of the opening 1021 in the extension direction of the accommodating cavity 103 is larger than the size of the extension portion 401 in the extension direction of the accommodating cavity 103, and the active stroke of the extension portion 401 in the opening 1021 is compatible with the active stroke of the button 2.

[0051] In the present application, the main body is located in the bearing section 1032, and the size of the main body in the extension direction of the accommodating cavity 103 is larger than the size of the opening 1021 in the extension direction of the accommodating cavity 103, thereby preventing the main body from entering the opening 1021 during movement, causing the overall matching block 4 to get stuck.

[0052] The present application further ensures that the extension portion 401 is separated from the limit block 6 by making the size of the opening 1021 in the extension direction of the accommodating cavity 103 larger than the size of the extension portion 401 in the extension direction of the accommodating cavity 103, thereby ensuring smooth unlocking of the control assembly 1.

[0053] Preferably, in the present application, the movable stroke of the extension portion 401 in the opening 1021 is compatible with the movable stroke of the button 2, that is, when the end face of the button 2 is flush with the end face of the gripping portion, the extension portion 401 is just in a separated state from the limit block 6. If the end face of the button 2 is not pressed into place, the extension portion 401 cannot be separated from the limit block 6, thereby failing to complete the unlocking, thereby being able to avoid, to a certain extent, the problem of false triggering of the handle 101 unlocking caused by the button 2 not being pressed into place.

[0054] Alternatively, if Figure 3 As shown, the extension portion 401 in the present application is formed with a notch 4011, and the shape of the notch 4011 is the same as the shape of the corner 601 of the limit block 6. The corner 601 can be embedded in the notch 4011, so that the extension portion 401 and the limit block 6 are snap-fitted together; the depth of the notch 4011 is not greater than the movable stroke of the extension portion 401 in the opening 1021.

[0055] Preferably, the extension portion 401 in the present application is in a rectangular block structure, and the above-mentioned notch 4011 is formed at a corner of the extension portion 401. Accordingly, the corner 601 of the limit block 6 can just fill the notch 4011, so that the limit block 6 and the extension portion 401 can be fully fitted and connected to achieve the stability of the limit between the two.

[0056] It can be understood that the present application makes the depth of the notch 4011 no greater than the movable travel of the extension portion 401 in the opening 1021, thereby avoiding the problem that after the button 2 is pressed into place, the corner 601 of the limit block 6 still does not leave the range of the notch 4011, causing the limit block 6 and the extension portion 401 to remain in a locked state and cannot be unlocked due to the notch 4011 being too deep.

[0057] More preferably, if Figure 3 Combination Figure 5 As shown, the limiting block 6 in the present application is fan-shaped, so that the extension portion 401 can slide along the arc surface 602 of the limiting block 6.

[0058] Since the control component 1 in the present application rotates with the rotating shaft 7 as the rotation center during operation, the present application makes the limit block 6 fan-shaped and the contact surface with the extension part 401 arc-shaped, so that after unlocking, the extension part 401 can slide along the arc-shaped surface 602 to play a guiding role, making the traction operation process smoother and more stable.

[0059] Alternatively, if Figure 4 Combination Figure 5 As shown, the control mechanism provided by the present invention also includes a feedback component, the control component 1 includes a control panel, a rotating shaft 7 and a limit cam 8, and the feedback component includes a second elastic member 15 and abutment 10; the second elastic member 15 is connected to the abutment 10, so that the abutment 10 has a tendency to move toward the limit cam 8; one end of the rotating shaft 7 is connected to the control panel, the limit cam 8 is arranged on the rotating shaft 7, and the contact surface between the limit cam 8 and the abutment 10 is arc-shaped, and a plurality of recesses 801 are formed on the contact surface, and the plurality of recesses 801 are arranged at intervals on the contact surface.

[0060] Preferably, the first elastic member 5 and the second elastic member 15 in the present application are both springs.

[0061] Through the second elastic member 15, the abutment 10 can always be in contact with the limit cam 8. Since the contact surface between the limit cam 8 and the abutment 10 in the present application is arc-shaped and has multiple recesses 801, when the limit cam 8 rotates with the rotating shaft 7, the abutment 10 can be aligned with the multiple recesses 801 in sequence. During the alignment process, under the action of the second elastic member 15, the abutment 10 is always in close contact with the contact surface of the limit cam 8, so that when the driver operates the handle 101 to rotate the turntable 102, a jerky feedback feel can be generated, thereby improving the driver's operating experience.

[0062] Preferably, the depths and widths of the plurality of recesses 801 in the present application are different.

[0063] The different widths of the recess 801 in the present application refer to different areas occupied by the recess 801 on the contact surface. By forming recesses 801 with different depths and widths, different jerking hand feelings can be fed back during the rotation process, thereby making the hand feeling of each different gear position different and making the gear positions clearer, more accurate and distinct.

[0064] Alternatively, if Figure 4 Combination Figure 5 As shown, the feedback assembly in the present application also includes a support 11, a positioning shaft 12, a mounting seat 13 and a connecting shaft 14; the support 11 and the mounting seat 13 are both arranged on the side of the positioning plate 9 away from the control panel, one end of the second elastic member 15 is connected to the mounting seat 13, and the other end is connected to one end of the support 11, the other end of the support 11 is connected to the positioning shaft 12, and the positioning shaft 12 is rotatably connected to the positioning plate 9; the connecting shaft 14 is arranged on the support 11, and the abutment 10 is arranged on the connecting shaft 14 and is rotatably connected to the connecting shaft 14.

[0065] The positioning plate 9 in the present application can provide an installation basis for the limit block 6, the mounting seat 13 and the positioning shaft 12. By setting the support 11, on the one hand, it can provide an installation basis for the abutment 10, and on the other hand, it can better adapt to the assembly angle of the limit cam 8, so that the abutment 10 can always be in contact with the limit cam 8 and will not affect the rotation of the limit cam 8.

[0066] Correspondingly, by setting the positioning shaft 12 on the positioning plate 9, the rotational connection between the support 11 and the positioning plate 9 can be achieved, and the mounting seat 13 can provide a mounting base for the second elastic member 15 to ensure the stable installation of the second elastic member 15 and realize the feedback function of the overall structure.

[0067] In addition, the present invention also provides a controller, including the above-mentioned control mechanism.

[0068] The driver controller using the control mechanism provided in the present application can greatly improve the reliability of the driver controller and avoid the problem of accidental touch affecting the safety of train operation because of the difference in the operating methods of traction and braking, and the driver cannot operate the traction direction without pressing the pressing component.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
