A mechanism for supporting the push-to-eject of a pin type connector electronic disk mainly comprises two parts: a functional module [3] and a frame [10] component. The function module [3] mainly has the functions of realizing the first pressing and limiting, the second pressing and releasing and the function of hooking the electronic disk [1 ]; the function of the frame [10] component is to provide power for ejecting the electronic disk [1], provide a pressing stroke for the plug-in of the connector of the electronic disk [1] and the motherboard [8], and transmit the displacement of the electronic disk [1] to the functional module [3 ].
The frame [10] provides an installation space for the electronic disk [1] and the motherboard [8 ]; along the inserting direction of the electronic disk [1], an electronic disk dead axle and a motherboard dead axle are fixed on the frame [10 ]; wherein the electronic disk dead axle is sleeved with an electronic disk tray [9] and an electronic disk dead axle spring [4], and the motherboard dead axle is sleeved with a motherboard tray [7] and a motherboard dead axle spring [5 ]; an opening for exposing the connector of the electronic disc [1] is arranged in the middle of the electronic disc tray [9], a mother board [8] is fixedly arranged on the mother board tray [7], and the connector of the mother board [8] corresponds to the connector of the electronic disc [1] in position;
when the electronic disk [1] is inserted into the frame [10], the electronic disk firstly contacts the electronic disk tray [9] and drives the electronic disk tray [9] to continue to be inserted and compress the electronic disk dead axle spring [4], and when the connector of the electronic disk [1] is contacted with the connector of the motherboard [8], the electronic disk [1] drives the motherboard [8] to continue to be inserted and compress the motherboard dead axle spring [5 ]; under the action of the insertion force of the electronic disk [1] and the pressure of the motherboard dead axle spring [5], the connector of the electronic disk [1] and the connector of the motherboard [8] can be inserted;
in the embodiment, two side surfaces of the frame [10] are provided with openings which are used as installation spaces of a fixed shaft of an electronic disk; the frame is internally provided with a bulge, and two ends of the fixed shaft of the motherboard are fixed on the bulge and the bottom surface of the frame; when the connector of the electronic disk [1] is contacted with the connector of the motherboard [8], the tray [9] of the electronic disk is limited by the bulge.
The functional module [3] comprises a base [16], a Y-shaped frame [15], a bolt [14], a spring hook [13], a sliding groove [12] and an upper cover [11 ]; the Y-shaped frame [15], the lock tongue [14], the spring hook [13] and the sliding groove [12] are arranged in a space formed between the base [16] and the upper cover [11 ]; the base (16) and the upper cover (11) are combined and then are arranged on the surface of the frame (10) through the fixing frame (2).
The sliding groove [12] and the bolt [14] are connected with the electronic disk tray [9] and can synchronously move in the installation space along with the electronic disk tray [9 ]; in this embodiment, a protruding key is designed on the tray [9] of the electronic disk, and a key slot is designed in the lock tongue [14] and the sliding slot [12], so as to realize the connection between the tray [9] of the electronic disk and the lock tongue [14] and the sliding slot [12 ]. A Y-shaped frame (15) is arranged in the rear space of the sliding chute (12); one end of the spring hook (13) is fixed in the base (16), and the other end is free.
When the electronic disk [1] drives the electronic disk tray [9] to insert, the sliding groove [12] and the bolt [14] synchronously move along with the electronic disk tray [9], and when the tip of the Y-shaped frame [15] is contacted with the free end of the spring hook [13], the self elasticity of the spring hook [13] can be overcome, so that the free end of the spring hook [13] moves along the profile of the Y-shaped frame [15 ]; after the connector of the electronic disk [1] is inserted into the connector of the mother board [8], the electronic disk [1] is continuously pressed, the free end of the spring hook [13] moves to the end surface of the rear space of the sliding groove [12], and an in-place signal of the electronic disk [1] is given; at the moment, the pressing force of the electronic disk [1] is removed, the electronic disk tray [9] is pushed to move outwards by the electronic disk dead axle spring [4], the free end of the spring hook [13] moves to the fork opening of the Y-shaped frame [15] under the action of self restoring force to form constraint, and the bolt [14], the chute [12] and the electronic disk tray [9] connected with the chute [12] are limited to move; meanwhile, the surface of the electronic disk [1] is provided with a surface groove which can be matched with the bolt [14], and the bolt [14] hooks the surface groove of the electronic disk [1] to form constraint.
When the electronic disk [1] is pressed again, the electronic disk tray [9] drives the sliding groove [12] and the bolt [14] to move, the free end of the spring hook [13] is separated from the fork of the Y-shaped frame [15] under the action of self restoring force, and the spring hook [13] does not restrain the sliding groove [12] and the bolt [14 ]; under the thrust action of the electronic disk dead axle spring [4], the connector of the electronic disk [1] is separated from the connector of the motherboard [8], and the electronic disk [1] is ejected; in the process of ejecting the electronic disk [1], the lock tongue [14] can be tilted by the base [16] to be separated from the groove on the surface of the electronic disk [1 ].
In the embodiment, the bolt [14] is matched with the surface groove of the electronic disk [1] in a wedge shape, and the length of the inclined surface of the bolt is greater than that of the inclined surface of the surface groove of the electronic disk [1], so that the bolt [14] can be conveniently tilted by the base [16 ].
In the embodiment, a space end face of a Y-shaped frame [15] arranged at the rear part of the sliding chute [12] is provided with a bulge, when the electronic disk [1] connector and the motherboard [8] connector are inserted, the electronic disk [1] is continuously pressed, the free end of the spring hook [13] moves to the space end face at the rear part of the sliding chute [12], and under the action of the restoring force of the spring hook [13], the free end of the spring hook [13] is in bulge contact with the space end face at the rear part of the sliding chute [12] to send out a sound signal that the electronic disk [1] is in place.
When an operator presses the electronic disk [1] for the first time, the electronic disk tray [9] drives the bolt [14] and the sliding groove [12] to move inwards, and the spring hook [13] slides along the outline of the Y-shaped frame [15] in the sliding groove [12 ]. In the process, the spring hook [13] is used as a cantilever beam fixed on the base [16], the flexibility is gradually increased, and the restoring force is provided. When the electronic disk [1] is pressed to the limit position, an operator looses his hand, and the electronic disk tray [9] drives the bolt [14] and the chute [12] to move outwards under the action of the electronic disk dead axle spring [4 ]. Meanwhile, the spring hook [13] is shifted to the position shown in figure 7 under the action of the self elasticity, and the outward displacement of the sliding chute [12] and the bolt [14] is prevented. At this time, the tray [9] of the electronic disk drives the electronic disk [1] to move outwards under the action of the fixed shaft spring [4] of the electronic disk, but the locking tongue [14] hooks the surface groove (shown in figure 10) of the electronic disk [1], and the electronic disk [1] reaches a stable state.
When an operator presses the electronic disk [1] again, the electronic disk tray [9] drives the lock tongue [14] and the sliding groove [12] to move inwards, the spring hook [13] is poked to the sliding way at the bottom of the sliding groove [12] under the action of the elasticity of the spring hook, and the sliding groove [12] and the lock tongue [14] are not limited any more. The electronic disk [1], the electronic disk tray [9], the sliding groove [12] and the bolt [14] are ejected outwards together under the action of the electronic disk dead axle spring [4], and when the bolt [14] reaches the position shown in figure 11, the bolt contacts the base [16] to upwarp, so that the electronic disk [1] is stopped being limited. The electronic disk [1] is ejected outwards under the action of the electronic disk tray [9] and the electronic disk dead axle spring [4 ]. The push-to-pop process ends.
The key for realizing the pressing and ejecting function is the design of the elastic coefficients of the electronic disc dead axle spring [4] and the motherboard dead axle spring [5 ]. The elastic coefficient of the electronic disk dead axle spring [4] is enough to ensure that the connector of the electronic disk [1] can be pulled out from the connector of the motherboard [8] after the electronic disk [1] is pressed for the second time; but the elastic coefficient of the dead axle spring [4] of the electronic disk cannot be too large, otherwise, the electronic disk [1] is difficult to press, and the ejecting force is possibly too large to cause the electronic disk [1] to fly out. The elastic coefficient of the motherboard dead axle spring [5] is also large enough to ensure that the motherboard [8] can provide enough supporting force to insert the connector in place after the electronic disk [1] is pressed for the first time; however, if the elastic coefficient of the motherboard dead axle spring [5] is too large, the pressing stroke is difficult to realize, and a large force is needed to press the electronic disk [1] in place.
Therefore, the elastic coefficients of the electronic disk dead axle spring [4] and the motherboard dead axle spring [5] need to be designed to satisfy the following relations:
4k4s4+4k5s5＜F (1)
4k4s4＞N (2)
4k5s5＞N (3)
wherein:
k4spring [4] for fixing shaft of electronic disk]The elastic coefficient;
s4is an electronic disk [1]Electronic disk dead axle spring [4] when pressed in place]Amount of compression of；
k5Spring for mother board dead axle [5]]The elastic coefficient;
s5is a mother board [8]Maximum design compression of (d);
f is the maximum pressing force accepted by the operator;
and N is the connector plugging force.
(1) The operation experience of an operator when the electronic disk [1] is pressed is guaranteed, and the experience can be changed by adjusting F;
(2) the electronic disk (1) can be smoothly pulled out of the motherboard (8) connector after the electronic disk (1) is pressed for the second time;
(3) the method ensures that the motherboard [8] has enough supporting force to insert the connector of the electronic disk [1] in place.
In order to ensure that the electronic disk [1] does not fly out due to overlarge elastic force when the electronic disk [1] is ejected, the electronic disk dead axle spring [4] can be designed into a spring with unequal pitch. When the compression amount is smaller, the spring elastic coefficient is smaller; when the compression amount is large, the elastic coefficient is large as shown in fig. 14. Therefore, the electronic disk [1] can be successfully pulled out of the motherboard [8] connector after the electronic disk [1] is pressed for the second time, and the electronic disk [1] can be prevented from flying out due to overlarge elasticity when being ejected.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
