In addition, the spring 15 acts to return the friction sleeve 20.
As for how to make the friction sleeve 20 enter the area where the second friction layer 21 is located, the key structure is that the soft rods 14, please refer to fig. 5 and 6, two soft rods 14 penetrate the first counterweight 4 and extend into the two wheel cavities 10 to connect with the friction sleeve 20, therefore, the inertia force generated by the instant of moving the door panel acts on the first counterweight 4 arranged in the counterweight cavity 11, so that the first counterweight 4 moves towards the opposite direction of the door panel moving direction, and the two soft rods 14 pull the friction sleeve 20 into the area where the second friction layer 21 is located, so as to reduce the rotation speed of the first wheel 3 and the second wheel 5 and force the door panel to slow down.
When the friction sleeve 20 rubs against the second friction layer 21, the turntable 6 is particularly provided to avoid the problem that the spring 15 is twisted due to the torsion force applied to the spring 15, and the elastic force of the spring 15 is reduced.
Specifically, referring to fig. 1-7, a turntable cavity is arranged in the interlayer between the wheel cavity 10 and the counterweight cavity 11, a turntable 6 coincident with the axis of the turntable cavity is arranged in the turntable cavity, referring to fig. 5 for emphasis, the turntable 6 extends upwards relative to the case 2, wherein a sector groove 19 with an open notch is arranged at the upwards extending part, and in addition, a second counterweight 23 embedded at the turntable 6 is arranged opposite to the sector groove 19.
The first counterweight 4 is also matched in a related manner, specifically, a limiting rod 8 extending towards the two turntables 6 is arranged at the first counterweight 4, a ring 12 in sliding contact with the groove surface of the fan-shaped groove 19 is arranged at each end part of the limiting rod 8, and accordingly, when the first counterweight 4 moves in the direction opposite to the sliding direction of the door plate, the second counterweight 23 which is lifted by rotation in the turntables 6 has gravitational potential energy, and the first counterweight 4 is pushed to reset by combining the movement trend of the turntables 6.
The embodiment is a further development of embodiment 2, in which after the first counterweight 4 moves in the opposite direction to the door panel moving direction, the friction time between the friction sleeve 20 and the second friction layer 21 is adjusted according to the distance of the opposite movement of the first counterweight 4.
Specifically, based on the configuration proposed in embodiment 2, the friction plates 7 in sliding fit with the spacer layer are disposed on both sides of the ring sleeve 12, wherein the spacer layer surface in sliding fit with the friction plates 7 has the first friction layer 18, as shown in fig. 6, the first friction layer 18 includes a plurality of friction particles, wherein the friction particles gradually increase from the central area of the box 2 toward both sides of the box 2, so that the friction resistance of the friction plates 7 sliding toward both sides of the box 2 is gradually increased on the spacer layer surface, therefore, in combination with the manner of disposing the first friction layer 18 and the sliding distance of the first counterweight 4 in the direction opposite to the sliding direction of the door panel, the time of the reset movement of the first counterweight 4 is adjusted, and the friction time of the two friction sleeves 20 and the second friction layer 21 at the rotating shaft 17, that is, in combination with the sliding speed of the door panel, is adaptively adjusted, so as to control the speed reduction time length, so as to obtain a better speed reduction effect.
The present embodiment, including embodiment 2, also provides a related design for the extreme situation, that is, the situation that the door panel obtains a great initial kinetic energy, and after releasing the kinetic energy, the sliding speed of the door panel after releasing the kinetic energy cannot be effectively limited by embodiment 1, embodiment 2 and the embodiments described hereinabove.
Specifically, referring to fig. 4-7, when the initial movement energy is too large, after the first counterweight 4 contacts the cavity end of the counterweight cavity 11, the ring 12 in sliding contact with the groove surface of the fan-shaped groove 19 is separated from the turntable 6, wherein the turntable 6 separated from the ring 12 is quickly reset under the pulling of the second counterweight 23, the reset turntable 6 forms a blocking part for blocking the reset movement of the first counterweight 4, further explaining that the turntable 6 forming the blocking part after the reverse movement can completely cover the friction sleeve 20 indirectly connected with the first counterweight 4 in the area where the second friction layer 21 is located and continuously located in the area, so that the first wheel 3 and the second wheel 5 are strongly decelerated until the door plate slides and stops.
There are two ways how the first counterweight 4 is unblocked by the turntable 6:
(1) referring to fig. 1-5 and 7, the first counterweight 4 extends downward from the case 2, wherein the downward extending portion allows a person to slide the first counterweight 4, so that the first counterweight 4 pushes the turntable 6, forces the turntable 6 to rotate downward, and the ring 12 enters the fan-shaped groove 19 again, and the first counterweight 4 is returned (the central area of the counterweight cavity 11) by combining the pulling of the spring 15 and the pushing of the turntable 6.
(2) The door panel is quickly pushed in the opposite direction to the sliding direction of the door panel (the personnel control door panel is in a controllable area), the turntable 6 is rotated downwards under the action of inertia in combination with the second counterweight 23, the ring sleeve 12 is forced to enter the fan-shaped groove 19 again, and the first counterweight 4 is reset (the central area of the counterweight cavity 11) in combination with the pulling of the spring 15 and the pushing of the turntable 6.
The following are what the above embodiments further need to illustrate:
(1) the spacer between the wheel cavity 10 and the weight cavity 11 has a hole for inserting the soft rod 14, and in embodiment 2 and embodiment 3, the axis of the turntable 6 has a circular hole corresponding to the hole, and the circular hole coincides with the hole axis.
(2) A second bearing 13 is arranged in a circular hole arranged in the turntable 6, and the second bearing 13 is fixed in the hole site, so that the turntable 6 can smoothly axially rotate in the turntable cavity without being interfered by a soft rod 14.
(3) For the spindle 17 connected to the first wheel 3 and the second wheel 5, the first bearing 9 is rotatably connected to the housing 2, i.e. the spindle 17 can extend into the second bearing 13 at most, and in addition the spindle 17 does not influence the movement of the soft rod 14 in the second bearing 13.
(4) The soft rod 14 is bendable but not resilient.
(5) As shown in fig. 6, the first weight 4 is provided with a groove 22 for moving the soft rod 14, specifically, the groove 22 provided at the first weight 4 forms a receiving space to the wall of the weight cavity 11, the receiving space is enough for the soft rod 14 to bend, so that the soft rod 14 bent in the weight cavity 11 is not clamped in the gap between the first weight 4 and the weight cavity 11.
In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.
