Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Composition graphs 2, a kind of mechanism of accumulation energy type motor-operating mechanism misoperation that prevents that the utility model provides is divided into two parts, respectively for two counterweight assembly 6 and balance elements 7 that the region of misoperation more easily occurs in fast electric behaviour actuator
The dynamic iron core 5 of electromagnet mechanism 1 only has when fast electric behaviour is in energy storage state, just can work.During electromagnet mechanism 1 no power, have spring handle to move position that iron core 5 is positioned at non-adhesive, but when thump acts on dynamic iron core 5, dynamic iron core 5 is because inertia arrives attracted position, and push rod 2 is rotated, and cam 4 loses spacing, makes fast electric grasp false switching.
For this reason, the utility model adds a counterweight assembly 6 as shown in Figure 3, it comprises lever 6-1, fixed by rotation axis 6-2 and support 6-3 in the middle part of lever 6-1, fixed the position of counterweight assembly 6 by support 6-3, the lever 6-1 moving axis 6-2 that rotates freely rotates, one end of lever 6-1 has mounting hole 6-6, brace 6-5 is fixed on dynamic iron core 5, and brace 6-5 is enclosed within mounting hole 6-6, and the other end of lever 6-1 is provided with the anti-block stamp 6-4 suitable with dynamic iron core 5 quality.
When being subject to instant impact, dynamic iron core 5 and anti-block stamp 6-4 can move because of inertia simultaneously, and because both are identical in quality, and the potential energy born is identical with displacement, and both lever 6-1 connects, energy offsets, and comes back to equilbrium position.Like this, dynamic iron core 5 just can not produce displacement and misoperation when being subject to impacting.
In fast electric behaviour, have a push rod 2 as shown in Figure 4, one end of push rod 2 is enclosed within dynamic iron core 5, and the other end withstands gag lever post 3.Dynamic iron core 5 is when free position, and push rod 2 can stop gag lever post 3 to rotate.When fast electric behaviour energy storage, cam 4 rotates, and is finally limited in gag lever post 3 place, and main extension spring stretches, and cam position is shown in Fig. 7.When fast electric behaviour closes a floodgate, dynamic iron core 5 adhesive, drive push rod 2 to rotate, after push rod 2 rotates, gag lever post 3 lower end is spacing to be removed, and cam 4 can turn over restriction site, spring is discharged, completes feed motion.
But this push rod 2 is not a dynamic balancing part, so when being subject to random impulsive force, may occur to rotate by mistake.Push rod 2 can make iron core 5 arrive misoperation position, cause the combined floodgate that whole fast electric is grasped after rotating, so the design for erosion protection of push rod 2 is also the emphasis point of fast electric behaviour protecting against shock.
Because in the Executive Module of fast electric behaviour, each part is compact, space is little, and add balance element and acquire a certain degree of difficulty, the utility model devises a balance element as shown in Figure 5.Utilize small space, complete the balanced design to push rod 2, exempt from dismounting, utilize push rod 2 itself to carry the rotating shaft of waist hole and push rod, complete the fixing of balance element 7 and push rod 2, utilize the space under cam 4 to place balance element.Composition graphs 6, the push rod 2 loaded after balance element 7 with the point of rotation 8 for barycenter, X-direction and Y direction can balance.Balance element 7 is loaded the regular event that whole Executive Module can not affect fast electric behaviour, also can not cause the stuck of cam 4 and gag lever post 3, effectively can prevent the misoperation that random shock power causes.
Although the utility model describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is only used to the utility model is described; should understand and wherein can make various changes and revise and not depart from the utility model in a broad sense; so be not that conduct is to restriction of the present utility model; as long as in spirit of the present utility model, all the protection range of the utility model claim will be fallen into the change of above-described embodiment, distortion.
