Technical Field

The present disclosure relates to locking structures, and particularly to a switch design of a locking structure.

Background

A common two-piece (two-piece) housing structure includes an upper housing and a lower housing, wherein the upper housing has a slot, and the lower housing is fastened to the slot by a fastening mechanism for fixing a relative position between the upper housing and the lower housing. On the contrary, after the buckling relation between the buckling mechanism and the clamping groove is released, the upper shell and the lower shell can move relatively.

The common buckle mechanism adopts a two-stage type operation design, and comprises a switch piece and a clamping hook, wherein the switch piece is pivoted with a lower shell, and the clamping hook is pivoted with the switch piece. The clamping hook is used for being buckled with the clamping groove of the upper shell. If the user intentionally releases the buckling relationship between the buckle mechanism and the slot, the user must first pull the switch upward to slightly lift the hook in the slot. Then, the user must manually pull the hook out of the slot to complete the step of releasing the buckling relationship between the buckle mechanism and the slot. On the contrary, if the user intentionally restores the buckling relationship between the buckle mechanism and the slot, the user must first pull the hook and move the hook into the slot. Then, the user must pull the switch downward to fasten the hook to the slot, so as to complete the step of recovering the fastening relationship between the fastening mechanism and the slot.

The above-mentioned operation steps are too cumbersome and not convenient for the user to operate.

Detailed Description

Fig. 1 is a schematic view of a locking structure according to an embodiment of the disclosure. Fig. 2 is a partially enlarged view of the locking structure of fig. 1 in a first mode. Fig. 3 is a partially enlarged view of fig. 2 from another view angle. Fig. 4 is a partial cross-sectional schematic view of fig. 2. Specifically, the second housing 130 of fig. 3 is partially omitted for clarity of the internal structure. Referring to fig. 1 to 4, in the present embodiment, the locking structure 100 can be applied to an electronic device, such as a ruggedized computer, a notebook computer, a chassis of a server, a chassis of a host computer, or other suitable users.

In detail, the locking structure 100 includes a first casing 110, an ejecting mechanism 120, a second casing 130 opposite to the first casing 110, and a switch mechanism 140, in a first mode, the switch mechanism 140 is in a closed state, wherein a relative position between the first casing 110 and the second casing 130 is fixed, and the first casing 110 covers the second casing 130.

The first housing 110 has a card slot 111, and the eject mechanism 120 is disposed in the card slot 111. The switch mechanism 140 is disposed on the second housing 130, and is used to fix the first housing 110 on the second housing 130 or separate the first housing 110 from the second housing 130. In detail, the switch mechanism 140 includes a switch 141, a first spring 142 and a hook 143, wherein the switch 141 is pivotally connected to the second housing 130 along a first axis a1, and the first spring 142 connects the second housing 130 and the switch 141. The first spring 142 may be an extension spring, wherein the number of the first springs 142 may be two, and two first springs 142 are arranged in parallel.

The hook 143 pivots the switch 141 along a second axis a2 parallel to the first axis a1, and the first axis a1 is not coaxial with the second axis a 2. In the first mode, the hook 143 rotates towards the first casing 110 about the second axis a2, and drives the switch 141 to move and stretch the two first springs 142, and the elastic restoring force of the two first springs 142 drives the switch 141 to make the switch 141 tend to rotate along the rotation direction R. At this time, the switch 141 applies a downward force to the hook 143, so that the hook 143 is locked to the slot 111 and presses against the eject mechanism 120.

Before the hook 143 is not locked to the slot 111, when the user pulls the hook 143 and moves the hook 143 into the slot 111, the switch 141 rotates in the reverse direction of the rotation direction R to stretch the two first springs 142. The elastic restoring force of the two stretched first springs 142 can drive the hook 143 through the switch 141, so that the hook 143 is automatically fastened to the slot 111. Therefore, the user does not need to manually pull the switch 141 to lock the hook 143 to the slot 111.

In the present embodiment, the eject mechanism 120 includes a second spring 121 and an eject plate 122, and two ends of the second spring 121 are respectively connected to the first housing 110 and the eject plate 122. The second spring 121 may be a compression spring, wherein the number of the second springs 121 may be two, and two second springs 121 are disposed in parallel in the slot 111. In the first mode, the hook 143 presses against the eject plate 122, and the two second springs 121 are compressed.

Referring to fig. 3 and 4, in the Z-axis, there is a height difference between the first axis a1, the second axis a2 and any one of the first springs 142, and the first axis a1 is located between the second axis a2 and any one of the first springs 142. Further, the switch 141 includes a top portion 141a close to the first casing 110 and a bottom portion 141b far from the first casing 110, wherein the hooks 143 are pivotally connected to the top portion 141a, and each of the first springs 142 is connected to the bottom portion 141 b. On the other hand, the position at which the first axis a1 extends through the switch member 141 falls substantially between the top portion 141a and the bottom portion 141 b. Therefore, the elastic restoring force of the two first springs 142 can drive the switch 141, so that the switch 141 rotates relative to the second housing 130 about the first axis a1, and drives the hook 143.

In the present embodiment, the second housing 130 has a recess 131 for accommodating a part of the switch mechanism 140. In detail, a part of the hook 143 and the switch 141 are located in the groove 131, wherein the first axis a1 and the second axis a2 extend through the groove 131, and a part of the first spring 142 extends into the groove 131 to connect the switch 141.

The groove 131 has a bottom surface 131a and two side surfaces 131b connected to the bottom surface 131a, and the two side surfaces 131b are juxtaposed on both sides of the bottom surface 131 a. On the other hand, the second housing 130 further has a first through groove 132 and two second through grooves 133, wherein the number of the first through grooves 132 may be two, and the two first through grooves 132 are juxtaposed on the bottom surface 131 a. The two first springs 142 are respectively disposed through the two first through grooves 132, wherein one end of each first spring 142 is located in the second housing 130, and the middle section of each first spring 142 passes through the corresponding first through groove 132, so that the other end of each first spring 142 extends into the groove 131 to connect the switch 141.

It should be noted that, the number of the first springs, the number of the first through grooves, and the number of the second springs are not limited in the present disclosure, and since the first through grooves are used to accommodate parts of the first springs, the number of the first through grooves is the same as the number of the first springs.

Referring to fig. 2 to 4, in the present embodiment, two second through grooves 133 are respectively located on two side surfaces 131b, and the switch mechanism 140 further includes a first shaft 144 extending along the first axis a1 and a second shaft 145 extending along the second axis a 2. The switch 141 is pivotally connected to the second housing 130 via a first shaft 144, and the hook 143 is pivotally connected to the switch 141 via a second shaft 145. The middle section of the first shaft 144 passes through the switch member 141 and is located in the groove 131.

The switch mechanism 140 further includes two positioning seats 146 installed in the second housing 130, and the two positioning seats 146 respectively correspond to the two second through grooves 133. For example, the two positioning seats 146 can be fixed in the second casing 130 by locking, clipping, bonding or other suitable mounting methods. The two ends of the first shaft 144 are respectively inserted into the two second through grooves 133, and are respectively inserted into the two positioning seats 146. That is, the two positioning seats 146 are located on the first axis a1, and are used for carrying the first shaft lever 144 and serving as a rotation fulcrum of the switch 141. On the other hand, the second shaft 145 is located in the groove 131, wherein the middle section of the second shaft 145 passes through the switch member 141, and both ends of the second shaft 145 are inserted into the hooks 143.

Fig. 5 is a partially enlarged view of the locking structure of fig. 1 in a second mode. Referring to fig. 2, 3 and 5, in the present embodiment, the switch element 141 further includes an extension portion 141c, and the extension portion 141c protrudes from the bottom portion 141b, so as to facilitate the user to pull the switch element 141. When the user pulls the switch 141 to rotate the switch 141 relative to the second housing 130 in the reverse direction of the rotation direction R, the switch 141 drives the hook 143 to move and separate from the slot 111. At this time, the elastic restoring force of the two compressed second springs 121 pushes the eject plate 122, and the hooks 143 are automatically ejected out of the first housing 110 by the eject plate 122. Therefore, the user does not need to pull the hook 143 out of the slot 111 by additional hand.

In the second mode, the switch mechanism 140 is in an on state, and the first housing 110 and the second housing 130 are movable relative to each other.

In summary, in the locking structure of the present disclosure, when the user pulls the switch to separate the hook from the slot, the elastic restoring force of the compressed ejecting mechanism can automatically eject the hook out of the slot. On the other hand, when the user pulls the hook and moves the hook into the slot, the elastic restoring force of the stretched first spring can drive the hook through the switch, so that the hook is automatically buckled in the slot. Therefore, the locking structure of the present disclosure has excellent operation convenience for users.

Although the present disclosure has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore, the scope of the present disclosure is to be defined by the appended claims.
