Description

Technical Field

[0001] This utility model relates to the field of locomotive and rolling stock braking control technology, and more specifically, to a locomotive brake controller handle with synchronously triggered side-slow micro-switches. Background Technology

[0002] The brake controller of a locomotive or rolling stock is the core device for interaction between the operator and the braking system. Its core function is to receive and convert the driver's braking and release commands, thereby precisely controlling the braking state of the locomotive or train. This controller adopts a modular design, integrating two major operating modules: an automatic brake lever and a separate brake lever.

[0003] The individual brake lever has a side-operated action. Usually, when the lever is rotated 7° to the side, it cannot press the micro switch below, causing the two micro switches to fail to switch synchronously.

[0004] Therefore, we have made improvements and proposed a locomotive brake controller handle that synchronously triggers a side-slow micro-switch. Utility Model Content

[0005] To achieve the above-mentioned objectives, this utility model provides a locomotive brake controller handle with a synchronously triggered side-slow micro-switch, in order to improve the aforementioned problems.

[0006] The application is as follows:

[0007] include:

[0008] The box has a through slot on its top surface and contains a rotating shaft, a turntable and a fixing block arranged coaxially inside.

[0009] The movable slot is formed on the fixed block;

[0010] A semi-circular rod is rotatably mounted on the fixed block, with its axis of rotation perpendicular to the axis of the turntable, and an operating lever at its top extending through a slot to the outside of the box.

[0011] A bending rod is rotatably mounted in the movable groove of the fixed block and is driven by a semi-circular rod to produce a slow lateral movement. A spring body is provided between the bending rod and the adjacent surface of the turntable.

[0012] A circular plate is elastically mounted on the fixed block and has elasticity in the direction of the turntable axis;

[0013] A connecting rod is provided on the housing and has at least two micro switch bodies located on the moving path of the circular plate;

[0014] When the operating lever presses against the bending rod, the bending rod rotates around the rotation point and squeezes the circular plate to simultaneously squeeze the two micro switch bodies.

[0015] Preferably, the through slot has an arc-shaped gap for the deflection of the operating lever.

[0016] Preferably, the operating lever and the semi-circular rod are integrally formed, and a wedge-shaped pressure block extending towards the bending rod is provided at its root;

[0017] The movable groove has an inclined surface that mates with the wedge-shaped pressure block;

[0018] When the operating lever is pressed to the side, the wedge-shaped pressure block slides along the inclined surface of the movable groove and is converted into a constant amplitude rotational displacement of the bent rod.

[0019] Preferably, the elastic arrangement of the circular plate includes two compression springs symmetrically distributed on both sides thereon;

[0020] The axis of the double compression spring is parallel to the axis of the turntable, and its two ends abut against the side of the circular plate and the inner wall of the fixed block, respectively.

[0021] Preferably, a rolling column is provided at the contact end between the bent rod and the circular plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] In the scheme of this application:

[0024] To address the problems in the prior art, this application establishes a displacement conversion mechanism that combines a wedge-shaped pressure block with a ramp, precisely converting the lateral displacement of the operating lever into a constant-amplitude rotation of the bending rod; it utilizes a rigid translational structure of a circular plate constrained by symmetrical double springs to force the trigger points of the two microswitches to be synchronously pressed; and by combining the low-friction transmission of the rolling column with the energy storage and reset mechanism of the spring body, it achieves the technical effects of millisecond-level synchronous triggering of electrical commands, efficient transmission of operating force, and smooth, impact-free reset of the mechanism.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 A locomotive brake controller handle for synchronously triggering a side-softening microswitch, comprising:

[0033] The box body 1 has a through groove 2 on its top surface and has a rotating shaft 3, a turntable 4 and a fixing block 5 arranged coaxially inside;

[0034] The movable slot 51 is formed on the fixed block 5;

[0035] The semi-circular rod 6 is rotatably mounted on the fixed block 5, and its axis of rotation is perpendicular to the axis of the turntable 4. An operating rod 61 is provided on its top, extending to the through groove 2 to the outside of the box body 1.

[0036] The bending rod 7 is rotatably mounted in the movable groove 51 of the fixed block 5 and is driven by the semi-circular rod 6 to produce a slow lateral movement. A spring body 71 is provided between the bending rod 7 and the adjacent surface of the turntable 4.

[0037] The circular plate 8 is elastically set on the fixed block 5 and has elasticity in the direction of the axis of the turntable 4;

[0038] A connecting rod 9 is disposed on the housing 1 and has at least two micro switch bodies 91 located on the moving path of the circular plate 8;

[0039] When the operating lever 61 presses against the bending lever 7, the bending lever 7 rotates around the rotation point and squeezes the circular plate 8 to simultaneously squeeze the two micro switch bodies 91.

[0040] When a lateral force is applied to the operating lever 61 within the arc-shaped gap of the through slot 2, the integrally formed operating lever 61 drives the semi-circular rod 6 to rotate, and the wedge-shaped pressure block at its root immediately embeds into the slope of the movable slot 51. The sliding of the wedge-shaped pressure block along the slope precisely converts the operator's lateral thrust into a constant-amplitude rotational displacement of the bent rod 7 around its rotation point. This linear conversion eliminates the interference of transmission backlash on the synchronization of the action.

[0041] When the bent rod 7 is driven to rotate, the rolling pin at its end begins to press against the surface of the circular plate 8. The rolling contact significantly reduces the frictional resistance between the bent rod 7 and the circular plate 8, ensuring efficient transmission of operating force. At the same time, the spring body 71 between the bent rod 7 and the turntable 4 is compressed, accumulating reset energy and providing smooth power for the subsequent return of the handle.

[0042] Driven by the rolling column, the circular plate 8 overcomes the resistance of the symmetrically arranged double compression springs and moves smoothly in a direction parallel to the axis of the turntable 4. The symmetrical arrangement of the double springs forces the circular plate 8 to maintain a translational posture, avoiding tilting caused by single-point pressure. This rigid translational motion causes the outer edge of the circular plate 8 to simultaneously contact the trigger points of the two microswitch bodies 91 on the connecting rod 9.

[0043] Because the rigid translational path of the circular plate 8 is precisely constrained by the two springs, and its direction of movement is strictly aligned with the triggering direction of the microswitch body 91, the triggering springs of the two microswitch bodies 91 are pressed down synchronously within milliseconds. This spatiotemporal consistency completely eliminates the signal delay difference that may exist in traditional series triggering, providing absolutely synchronized electrical commands for the locomotive braking system.

[0044] After the lateral force is released, the bending rod 7 rotates in the opposite direction under the reset action of the spring body 71, and the wedge-shaped pressure block retracts along the ramp of the movable groove 51. At the same time, the circular plate 8 is reset under the push of the double compression spring, and the spring of the micro switch body 91 pops up to disconnect the circuit. The operating rod 61 smoothly returns to its original position under the guidance of the arc-shaped gap of the through groove 2, and the entire mechanism completes a shock-free reset cycle. The low-friction engagement between the rolling column and the circular plate 8 significantly reduces the reset resistance during this process, extending the service life of the mechanism.

[0045] The through slot 2 has an arc-shaped gap for the operation lever 61 to deflect. This arc-shaped gap precisely guides the lateral movement trajectory of the operation lever 61, eliminates rigid friction with the housing 1, makes the lateral pressing action smooth and without jamming, and provides maximum offset space.

[0046] The operating lever 61 and the semi-circular lever 6 are integrally formed, and a wedge-shaped pressure block extending towards the bent lever 7 is provided at its root.

[0047] The movable groove 51 has an inclined surface that mates with the wedge-shaped pressure block;

[0048] When the operating lever 61 is pressed to the side, the wedge-shaped pressure block slides along the inclined surface of the movable groove 51 and is converted into a constant amplitude rotational displacement of the bent rod 7;

[0049] The integrated structure of the operating lever 61 and the semi-circular rod 6 drives the wedge-shaped pressure block to embed into the inclined surface of the movable groove 51. The inclined surface forces the arc motion of the operating lever 61 into the constant amplitude rotational displacement of the bending rod 7.

[0050] The elastic setting of the circular plate 8 includes two compression springs symmetrically distributed on both sides of it;

[0051] The axis of the double compression spring is parallel to the axis of the turntable 4, and its two ends abut against the side of the circular plate 8 and the inner wall of the fixing block 5, respectively.

[0052] When the bending rod 7 pushes the circular plate 8, the symmetrically arranged double compression springs generate equal reaction forces along the axis of the turntable 4, forcing the circular plate 8 to move vertically rather than tilt. The complete parallelism between the spring axis and the trigger direction of the micro switch allows the operating force to be converted into the linear displacement of the circular plate 8 with zero loss, ultimately causing the outer edge of the circular plate 8 to simultaneously press the trigger points of the two micro switch bodies 91, achieving absolute synchronization of the electrical signals.

[0053] A rolling column is provided at the contact end between the bent rod 7 and the circular plate 8 to replace sliding friction with rolling friction, thereby reducing frictional wear of the parts.

[0054] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
