The driver controller with the interlocking function adopts a set of interlocking mechanism 6 to realize the interlocking among the key switch 1, the mode switching handle 2 and the main control handle 3 (the interlocking relationship is that the mode switching handle 2 and the main control handle 3 cannot be operated when the key switch 1 is in a locking state, the main control handle 3 can be operated when the mode switching handle 2 is in a forward gear, a backward gear or other gears, the key switch 1 cannot be operated at the same time, and the mode switching handle 2 and the key switch 1 cannot be operated when the main control handle 3 is in an operating state), so that the integral structure is simple, the operation is simple and convenient, and the reliability is high.
In this embodiment, the interlocking mechanism 6 includes an interlocking cam 602, an interlocking lever 601, a gear 603, and a stopper 604; the interlock cam 602 is sleeved on the rotating shaft of the key switch 1 and rotates along with the rotation of the rotating shaft of the key switch 1; the gear 603 is sleeved on the rotating shaft of the mode switching handle 2 and rotates along with the rotation of the rotating shaft of the mode switching handle 2; the middle part of the interlocking rod 601 is rotatably arranged (for example, the interlocking rod is rotatably arranged at the shell of a driver controller through a rotating shaft, and the like), one end of the interlocking rod is meshed with the gear 603, and a matched contour line is arranged between the other end of the interlocking rod and the edge of the interlocking cam 602; one end of the limiting rod 604 is fastened with the interlocking rod 601, and the other end of the limiting rod extends into the clamping groove 502 of one of the cams 501 on the cam shaft 5, of course, the cam 501 can be the cam 501 on the cam shaft 5, and only the clamping groove 502 needs to be formed in the cam 501; in other embodiments, a separate cam 501 may be provided on the camshaft 5. Specifically, the other end of the interlock lever 601 is provided with an arc-shaped concave portion 6011 and arc-shaped convex portions 6012 located on both sides of the arc-shaped concave portion 6011, and the arc-shaped concave portion 6011 and the arc-shaped convex portions 6012 located on both sides of the arc-shaped concave portion 6011 form a contour line of the interlock lever 601; the edge of the interlock cam 602 is provided with the female portion 6021 and the male portion 6022, and the female portion 6021 and the male portion 6022 form the contour line of the interlock cam 602. The interlocking mechanism 6 is linked with the key switch 1 and the mode switching handle 2 through two ends of the interlocking rod 601, and then linked with the cam 501 on the interlocking cam 602 through the limiting rod 604 on the interlocking rod 601, so that the interlocking mechanism is simple in overall structure, simple and convenient to operate, high in reliability and convenient to maintain.
As shown in fig. 2, in the present embodiment, when the key switch 1 is in the locked state, the external convex part 6022 of the interlock cam 602 on the rotating shaft of the key switch 1 and the arc-shaped concave part 6011 of the interlock lever 601 cooperate with each other to lock the interlock lever 601, so as to limit the rotation of the mode switching handle 2 engaged with one end of the interlock lever 601, and at the same time, the limiting rod 604 extends into the slot 502 of the cam 501 on the cam shaft 5 to limit the rotation of the cam shaft 5, so as to limit the operation of the main control handle 3, so that when the key switch 1 is in the locked state, neither the mode switching handle 2 nor the main control handle 3 can be;
when the key switch 1 is turned to be in the on state, as shown in fig. 3; at this time, when the operation mode switching handle 2 rotates to the forward gear, the gear 603 also synchronously rotates, so as to drive the interlocking lever 601 to rotate, and finally, the arc-shaped convex part 6012 of the interlocking lever 601 is clamped into the concave part 6021 of the interlocking cam 602, as shown in fig. 4, at this time, the key switch 1 cannot rotate, that is, the key switch 1 cannot be operated when being in the on state; at this time, the limiting rod 604 also completely exits from the clamping groove 502 of the cam 501 on the cam shaft 5, and the main control handle 3 can be operated at this time; in the above-mentioned cooperation process, by adjusting the position of the rotation point of the interlock lever 601, when the mode switching handle 2 is in the forward gear, the limiting rod 604 just completely exits from the slot 502 of the cam 501, that is, in the rotation process of the mode switching handle 2, the limiting rod 604 does not completely exit from the slot 502; similarly, the process of rotating the operation mode switching lever 2 to the reverse shift position is the same as the above-described process, and when the operation mode switching lever 2 is in the reverse shift position, the key switch 1 is restricted from being operated by the other arc-shaped projection 6012 of the interlock lever 601 being caught in the inner recess 6021 of the interlock cam 602, as shown in fig. 5;
when the main control handle 3 operates the cam shaft 5 to rotate, the engaging groove 502 of the cam 501 on the cam shaft 5 leaves the initial position, one side of the cam 501 abuts against the limiting rod 604, and at this time, the limiting rod 604 cannot return, so that the mode switching handle 2 can be limited to return or switch to another mode, as shown in fig. 6. The whole operation process is simple and convenient, and the reliability is high.
As shown in fig. 1, in the present embodiment, the transmission member 4 is a gear assembly, and the gear assembly includes a plurality of gears, and the plurality of gears are engaged with each other; the main control handle 3 drives the cam shaft 5 to rotate through the gear assembly, and the cam 501 on the cam shaft 5 can be driven to rotate in a large angle by the small rotating angle of the main control handle 3 through the gear assembly; the limit lever 604 limits the cam 501 on the cam shaft 5 (which is different from the direct limit of the main control handle 3), so as to indirectly control the main control handle. Because the cam 501 on the camshaft 5 has a large rotation angle, the locking precision can be ensured more easily, the requirement on the locking precision of the limiting rod 604 is not high, the manufacturing and mounting processes of all parts of the interlocking mechanism 6 are reduced, and the cost is reduced to a certain extent.
