Description

Technical Field

[0001] This invention relates to the field of railway vehicle control structure technology, and in particular to a control mechanism and driver controller. Background Technology

[0002] The driver's controller is an important control device for railway locomotives, EMUs, etc., used to operate the locomotive for reversing direction and adjusting speed. Most of the traction speed control mechanisms in the driver's controller can realize the operation of vehicle speed change and braking. However, in the current driver's controller, the traction speed control mechanism only differs in direction when operating, that is, pulling forward is traction, and pulling backward is braking.

[0003] While this method can achieve the control function, it is prone to misoperation. If the traction speed control mechanism pushes in the wrong direction when braking is required, it will pose a significant safety hazard to the train's operation.

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

[0005] The purpose of this invention is to provide a control mechanism and driver controller to optimize the driver controller structure to a certain extent, differentiate between traction and braking operations, and avoid misoperation.

[0006] This invention provides a control mechanism, including a control component, an unlocking mechanism, a positioning plate, and a limiting block. The control component has a receiving cavity extending axially along its axis. The unlocking mechanism is disposed within the receiving cavity and is slidable relative to the control component. The unlocking mechanism includes a pressing component, a first elastic member, and a mating 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 mating block. One end of the first elastic member abuts against the bottom of the receiving cavity, and the other end abuts against the other end of the mating block. The control component has an opening corresponding to the position of the mating block, communicating with the receiving cavity. The limiting block is installed on the positioning plate at the position corresponding to the opening, and the mating block has an extension portion. In its natural state, the extension portion of the first elastic member engages with the edge of one end of the limiting block.

[0007] The pressing component includes a button and a spindle. One end of the spindle is connected to the button, which protrudes from the end of the control component. The other end of the spindle abuts against the mating block.

[0008] Specifically, the receiving cavity includes a connecting section and a supporting section. The diameter of the supporting section is larger than the diameter of the connecting section. The mandrel is located inside the connecting section, and the mating block and the first elastic element are located inside the supporting section. When the button is pressed, the end of the mandrel away from the button can enter the supporting section and abut against the mating block, pushing the mating block to compress the first elastic element.

[0009] Furthermore, the mating block also includes a main body located within the bearing section, the extension being connected to the main body and located within the opening; the opening is larger in the direction of extension of the receiving cavity than the extension in the direction of extension of the receiving cavity, and the travel of the extension within the opening is adapted to the travel of the button.

[0010] Furthermore, the extension has a notch, the shape of which is the same as the corner of the limiting block, and the corner can be inserted into the notch, so that the extension and the limiting block are engaged; the depth of the notch is not greater than the travel distance of the extension within the notch.

[0011] The limiting block is fan-shaped, allowing the extension to slide along the arc-shaped surface of the limiting block.

[0012] Specifically, the control mechanism provided by the present invention further includes a feedback component, which includes a control panel, a rotating shaft, and a limiting cam. The feedback component includes a second elastic element and a contact element. The second elastic element is connected to the contact element, causing the contact element to tend to move toward the limiting cam. One end of the rotating shaft is connected to the control panel. The limiting cam is disposed on the rotating shaft, and the contact surface between the limiting cam and the contact element is arc-shaped, with multiple recesses formed on the contact surface. The multiple recesses are spaced apart on the contact surface.

[0013] Furthermore, the depth and width of the plurality of recesses are different.

[0014] Furthermore, the feedback component also includes a support, a positioning shaft, a mounting base, and a connecting shaft; the support and the mounting base are both disposed on the side of the positioning plate opposite to the control panel; one end of the second elastic member is connected to the mounting base, 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 disposed on the support, and the abutment member is disposed on the connecting shaft and rotatably connected to the connecting shaft.

[0015] Compared with existing technologies, the control mechanism provided by this 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 limiting block. A receiving cavity is formed within the control component, extending axially along the control component. The unlocking mechanism is disposed within the receiving cavity and is slidable relative to the control component. The unlocking mechanism includes a pressing component, a first elastic member, and a mating 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 mating block. One end of the first elastic member abuts against the bottom of the receiving cavity, and the other end abuts against the other end of the mating block. The control component has an opening corresponding to the position of the mating block that communicates with the receiving cavity. The limiting block is installed on the positioning plate at the position corresponding to the opening, and the mating block has an extension portion. In its natural state, the extension portion of the first elastic member engages with one end of the limiting block.

[0017] Analysis shows that the unlocking mechanism can be accommodated by the cavity formed along the axial direction of the control component. The unlocking mechanism in this application includes a pressing component, a first elastic element, and a mating block. Since one end of the pressing component protrudes from one end of the control component, it is convenient for the driver to operate. Correspondingly, when the control component is pressed down, the mating block can be pushed down to press down the first elastic element, so that the first elastic element obtains a restoring force.

[0018] Since the mating block in this application has an extension, and the control component has an opening corresponding to the extension that communicates with the receiving cavity, and the positioning plate has a limiting block corresponding to the opening, and the extension engages with the limiting block when the first elastic member is in its natural state, when the driver does not press down on the pressing component, the extension engages with the limiting block under the action of the first elastic member.

[0019] Furthermore, since the extension portion engages with the edge of one end of the limiting block in this application, when the pressing component is not pressed down, the driver can only operate the control component to rotate the extension portion away from the limiting block. When the driver presses down the pressing component, the pressing component drives the mating block to press down, allowing the extension portion to disengage from the end of the limiting block, thereby enabling the extension portion to move towards the other end of the limiting block.

[0020] In other words, when the pressing component is not depressed, the driver's action of operating the control component is a braking operation, while when the pressing component is depressed, the driver's action of operating the control component is a traction operation. Therefore, in actual operation, when it is necessary to change gears and traction, the driver needs to press the pressing component. If the pressing component is not depressed, the control component can only perform a braking operation, thus creating a difference between braking and traction operations and avoiding the problem of accidental operation affecting vehicle driving safety.

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

[0022] The driver controller using the control mechanism provided in this application can greatly improve the reliability of the driver controller because the operation methods of traction and braking are different, and the driver cannot operate in the traction direction when the pressing component is not pressed down. This avoids the problem of accidental contact affecting the safety of train operation. Attached Figure Description

[0039] like Figures 1-5 As shown, the present invention provides a control mechanism, including a control component 1, an unlocking mechanism, a positioning plate 9, and a limiting block 6; a receiving cavity 103 is formed in the control component 1, the receiving cavity 103 extends along the axial direction of the control component 1, the unlocking mechanism is disposed in the receiving 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 mating 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 mating block 4, one end of the first elastic member 5 abuts against the bottom of the receiving cavity 103, and the other end abuts against the other end of the mating block 4; the control component 1 has an opening 1021 corresponding to the position of the mating block 4, which communicates with the receiving cavity 103, the limiting block 6 is installed on the positioning plate 9 corresponding to the position of the opening 1021, and the mating block 4 has an extension 401, in the natural state, the extension 401 of the first elastic member 5 is engaged with the edge of one end of the limiting block 6.

[0040] Compared with existing technologies, the control mechanism provided by this invention has the following advantages:

[0041] The control mechanism provided by the present invention can accommodate the unlocking mechanism through the receiving cavity 103 formed along the axial direction of the control component 1. The unlocking mechanism in this application includes a pressing component, a first elastic member 5 and a mating 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 mating block 4 can be pushed down 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 this application has an extension 401, and the control component 1 has an opening 1021 corresponding to the position of the extension 401 that communicates with the receiving cavity 103, and the positioning plate 9 has a limiting block 6 corresponding to the position of the opening 1021, and the first elastic member 5 is in its natural state, the extension 401 is engaged with the limiting block 6. Therefore, when the driver does not press down the pressing component, the extension 401 is engaged with the limiting block 6 under the action of the first elastic member 5.

[0043] Furthermore, since the extension 401 engages with the edge of one end of the limiting block 6 in this application, when the pressing component is not pressed down, the driver can only operate the control component 1 to rotate the extension 401 away from the limiting block 6. When the driver presses down the pressing component, the pressing component drives the mating block 4 to press down, allowing the extension 401 to disengage from the end of the limiting block 6, thereby enabling the extension 401 to move towards the other end of the limiting block 6.

[0044] When the pressing component is not depressed, the driver's action of operating control component 1 is a braking operation; when the pressing component is depressed, the driver's action of operating control component 1 is a traction operation. Therefore, in actual operation, when it is necessary to change gears and traction, the driver needs to press the pressing component. If the pressing component is not depressed, control component 1 can only perform a braking operation, thus creating a difference between braking and traction operations and avoiding the problem of misoperation affecting vehicle driving safety.

[0045] Optionally, such as Figure 2 As shown, the pressing component in this application includes a button 2 and a spindle 3. One end of the spindle 3 is connected to the button 2, and the button 2 protrudes from the end of the control component 1; the other end of the spindle 3 abuts against the mating block 4.

[0046] Preferably, the control panel described in this application includes a handle 101 and a turntable 102. The handle 101 has a grip portion, and a receiving groove is formed in the end of the grip portion. One end of the button 2 is disposed in the receiving groove, and the other end protrudes from the grip portion. A spring is provided in the receiving groove, which can push the button 2 to protrude from the end of the grip portion. Correspondingly, one end of the spindle 3 passes through the spring and is connected to the button 2. Therefore, when the button 2 is released, the button 2 can automatically return to its original position.

[0047] It is understood that since the mating block 4 in this application is located inside the turntable 102, the spindle 3 can transmit pressure to the mating block 4 when the button 2 is operated, so that the mating block 4 can be pressed down to unlock the extension 401 and the limit block 6.

[0048] Optionally, such as Figure 2 As shown, the receiving cavity 103 in this application includes a connecting section 1031 and a supporting section 1032. The diameter of the supporting section 1032 is larger than the diameter of the connecting section 1031. The mandrel 3 is located inside the connecting section 1031, and the mating block 4 and the first elastic member 5 are located inside the supporting section 1032. When the button 2 is pressed, the end of the mandrel 3 away from the button 2 can enter the supporting section 1032 and abut against the mating block 4, pushing the mating block 4 to compress the first elastic member 5.

[0049] The diameter of the mating block 4 in this application is larger than the diameter of the mandrel 3, so that it can be stably located within the bearing section 1032. The connecting section 1031 formed can achieve contact between the mandrel 3 and the mating block 4 on the one hand, and also guide the mandrel 3 on the other hand, avoiding the problem of the mandrel 3 being deviated and damaged during movement.

[0050] Optionally, such as Figure 2 As shown, the mating block 4 in this application also includes a main body, which is located within the bearing section 1032. An extension 401 is connected to the main body and is located within the opening 1021. The dimension of the opening 1021 in the extending direction of the receiving cavity 103 is greater than the dimension of the extension 401 in the extending direction of the receiving cavity 103, and the travel of the extension 401 within the opening 1021 is adapted to the travel of the button 2.

[0051] In this application, the main body is located inside the bearing section 1032, and the size of the main body in the extending direction of the receiving cavity 103 is larger than the size of the opening 1021 in the extending direction of the receiving cavity 103. This can prevent the main body from entering the opening 1021 during the movement, which would cause the overall mating block 4 to jam.

[0052] Furthermore, this application makes the size of the opening 1021 in the extending direction of the receiving cavity 103 larger than the size of the extension 401 in the extending direction of the receiving cavity 103, thereby ensuring the separation of the extension 401 from the limiting block 6, and thus ensuring the smooth unlocking of the control component 1.

[0053] Preferably, in this application, the travel of the extension 401 within the opening 1021 is adapted to the travel of the button 2. That is, when the end face of the button 2 is level with the end face of the grip, the extension 401 is just separated from the limiting block 6. If the end face of the button 2 is not pressed in place, the extension 401 cannot be separated from the limiting block 6, thus failing to unlock. This can, to a certain extent, avoid the problem of false triggering of the handle 101 unlocking due to the button 2 not being pressed in place.

[0054] Optionally, such as Figure 3 As shown, the extension 401 in this application has a notch 4011. The shape of the notch 4011 is the same as the shape of the corner 601 of the limiting block 6. The corner 601 can be inserted into the notch 4011, so that the extension 401 and the limiting block 6 are engaged. The depth of the notch 4011 is not greater than the travel of the extension 401 within the opening 1021.

[0055] Preferably, the extension 401 in this application has a rectangular block structure, and the notch 4011 is formed at one corner of the extension 401. Correspondingly, the corner 601 of the limiting block 6 can just fill the notch 4011, so that the limiting block 6 and the extension 401 can fit together fully and achieve the stability of the limiting between the two.

[0056] It is understandable that by ensuring that the depth of the notch 4011 is no greater than the travel distance of the extension 401 within the opening 1021, this application can avoid the problem that if the depth of the notch 4011 is too large, the corner 601 of the limiting block 6 will not be disengaged from the notch 4011 after the button 2 is pressed down, thus keeping the limiting block 6 and the extension 401 in a stuck state and unable to unlock.

[0057] More preferably, such as Figure 3 Combination Figure 5 As shown, the limiting block 6 in this application is fan-shaped, allowing the extension 401 to slide along the arc surface 602 of the limiting block 6.

[0058] Since the control component 1 in this application rotates around the rotating shaft 7 as the rotation center during operation, this application makes the limiting block 6 fan-shaped and the contact surface that contacts the extension 401 arc-shaped, so that after unlocking, the extension 401 can slide along the arc-shaped surface 602, which plays a guiding role and makes the traction operation process smoother and more stable.

[0059] Optionally, such as Figure 4 Combination Figure 5 As shown, the control mechanism provided by the present invention further includes a feedback component. The control component 1 includes a control panel, a rotating shaft 7, and a limiting cam 8. The feedback component includes a second elastic member 15 and a contact member 10. The second elastic member 15 is connected to the contact member 10, so that the contact member 10 has a tendency to move towards the limiting cam 8. One end of the rotating shaft 7 is connected to the control panel. The limiting cam 8 is disposed on the rotating shaft 7, and the contact surface between the limiting cam 8 and the contact member 10 is arc-shaped, and a plurality of recesses 801 are formed on the contact surface, and the plurality of recesses 801 are spaced apart on the contact surface.

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

[0061] The second elastic element 15 ensures that the abutment 10 is always in contact with the limiting cam 8. Since the contact surface between the limiting cam 8 and the abutment 10 is arc-shaped and has multiple recesses 801, when the limiting 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 element 15, the abutment 10 is always in close contact with the contact surface of the limiting cam 8. As a result, when the driver operates the handle 101 to rotate the turntable 102, a jerky feedback feel can be generated, improving the driver's operating experience.

[0062] Preferably, the depth and width of the plurality of recesses 801 in this application are different.

[0063] The different widths of the recesses 801 in this application refer to the different areas occupied by the recesses 801 on the contact surface. By forming recesses 801 with different depths and widths, different tactile feedback can be provided during rotation, thereby making the feel of each gear different and making the gear positions clearer, more accurate and distinct.

[0064] Optionally, such as Figure 4 Combination Figure 5 As shown, the feedback component in this application also includes a support 11, a positioning shaft 12, a mounting base 13, and a connecting shaft 14; the support 11 and the mounting base 13 are both disposed 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 base 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 disposed on the support 11, and the abutment member 10 is disposed on the connecting shaft 14 and is rotatably connected to the connecting shaft 14.

[0065] The positioning plate 9 in this application can provide an installation base for the limiting block 6, the mounting base 13 and the positioning shaft 12. By setting the support 11, on the one hand, it can provide an installation base for the abutment 10, and on the other hand, it can better adapt to the assembly angle of the limiting cam 8, so that the abutment 10 can always be in contact with the limiting cam 8 without affecting the rotation of the limiting cam 8.

[0066] Correspondingly, by setting a positioning shaft 12 on the positioning plate 9, a rotational connection between the support 11 and the positioning plate 9 can be realized, and the mounting base 13 can provide an installation foundation for the second elastic element 15, ensuring the stable installation of the second elastic element 15 and realizing the feedback function of the overall structure.

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

[0068] The driver controller using the control mechanism provided in this application can greatly improve the reliability of the driver controller because the operation methods of traction and braking are different, and the driver cannot operate in the traction direction when the pressing component is not pressed down. This avoids the problem of accidental contact affecting the safety of train operation.

[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 principles of the present invention should be included within the protection scope of the present invention.
