Referring to FIG. 1 to FIG. 4, the present disclosure provides an electronic device with an extraction device. The electronic device 9 (as shown in FIG. 6) includes a main body 90, and the main body 90 has a receiving groove 901 and a notch 902. The extraction device 100 is detachably disposed in the receiving groove 901, and the notch 902 serves as an entrance and an exit of the receiving groove 901. For example, the electronic device 9 in the present embodiment can be, for example, a notebook computer, a tablet computer, or an industrial computer, but the present disclosure is not limited thereto.

The extraction device 100 is detachably disposed in the receiving groove 901 of the electronic device 9 (as shown in FIG. 8 and FIG. 9) along an extraction direction (e.g., an X-axis direction in FIG. 1). In the present embodiment, the extraction direction is a direction away from the electronic device 9, and is also a longitudinal direction of the electronic device 9.

Referring to FIG. 2 and FIG. 3, the extraction device 100 includes a housing 10 and a handle 20. A front side of the housing 10 has two ends, one of the two ends has a pivot C, and another one of the two ends has a limiting member 30. The housing 10 in the present embodiment is formed by connecting an upper casing 10a and a lower casing 10b to each other. The limiting member 30 has at least one limiting recessed portion 31 that is formed along a sliding direction (e.g., a Y-axis direction in FIG. 1, and a sliding direction D1 in FIG. 6). In the present embodiment, each of both sides of the limiting member 30 has a limiting recessed portion 31. In other words, the limiting recessed portion 31 is perpendicular to the extraction direction of the extraction device 100, so that the limiting member 30 can limit the movement of the handle 20 in the extraction direction.

For example, the extraction device 100 in the present embodiment may be a removable storage device. Referring to FIG. 1, a storage unit 40 is accommodated inside the housing 10, and the storage unit 40 is, for example, a memory or a hard disk, but the present disclosure is not limited thereto. A rear side of the extraction device 100 has two connectors 50 that are electrically connected to the electronic device 9 to transmit data or signals, but the present disclosure is not limited thereto.

Referring to FIG. 1 and FIG. 3, the handle 20 has a draw bar 21 and a hook 22. The draw bar 21 has a pivot end 211 and an operation end 212. The pivot end 211 of the draw bar 21 has a long groove 210 that is formed along a longitudinal direction of the draw bar 21. A pulling and gripping portion 213 is formed on the operation end 212 of the draw bar 21, and is connected to the hook 22. An operator can hold the pulling and gripping portion 213 to operate the handle 20, which makes it easier for the operator to apply force. The pivot C of the housing 10 is disposed in the long groove 210 of the draw bar 21, and the hook 22 is configured to be engaged into the limiting recessed portions 31 along the sliding direction (e.g., a Y-axis direction in FIG. 1, and a sliding direction D1 in FIG. 6) to be in an engaged state (as shown in FIG. 6). At the same time, the hook 22 is blocked at an inner edge of the notch 902 of the electronic device 9. Thereby, the extraction device 100 is blocked and fixed inside the receiving groove 901 of the electronic device 9.

In the present embodiment, a material of the hook 22 is different from that of the draw bar 21. The draw bar 21 is made of an elastic material, the hook 22 is made of a rigid material, and the hook 22 is integrally connected to the draw bar 21. For example, the draw bar 21 and the hook 22 can be manufactured by double-material injection molding to form a one-piece structure. The advantage of the above arrangement of materials is that the draw bar 21 has elasticity and can be operated more comfortably by the operator, and the elasticity of the draw bar 21 can prevent a breakage of a rotating shaft caused by improper operation. The hook 22 has rigidity and can be firmly engaged with the limiting member 30. The structural strength of the hook 22 is strong and can be used as a lock to be fixed in the notch 902 of the electronic device 9.

Referring to FIG. 3, in the present embodiment, in order for the operator to conveniently hold the handle 20, the draw bar 21 has a finger-accommodating groove 215 that is formed on one of two sides of the pulling and gripping portion 213, and the draw bar 21 has an anti-slip protrusion 2132 that is formed on another one of the two sides of the pulling and gripping portion 213. The finger-accommodating groove 215 can be used for one of the fingers to easily exert force on the draw bar 21, and the anti-slip protrusion 2132 further provides a non-slip function for another one of the fingers to exert more force on the handle 20, especially when the force is applied along an unlocking direction D2.

Referring to FIG. 6, the present embodiment can strengthen a bonding strength between the draw bar 21 and the hook 22. The hook 22 has an upper protruding portion 227 facing the pulling and gripping portion 213. The upper protruding portion 227 may be, for example, in a plate shape or a columnar shape. In the present embodiment, the pulling and gripping portion 213 can cover the upper protruding portion 227 through the double-material injection molding technology. A connecting hole 228 is formed on a rear end of the hook 22, and the connecting hole 228 is, for example, a cylindrical hole. Moreover, a bottom of the pulling and gripping portion 213 has a lower protruding portion that is formed toward the hook 22 through the double-material injection molding technology, so that the lower protruding portion 2133 extends into the connecting hole 228. Accordingly, an inside of the draw bar 21 and the hook 22 are engaged with each other, so that a bonding strength of the structure is stronger.

Referring to FIG. 7, the handle 20 can slide for a straight-line distance along an unlocking direction D2 (i.e., a negative Y-axis direction in FIG. 1 and FIG. 3) opposite to the sliding direction D1, so that the hook 22 in the engaged state departs from the limiting recessed portions 31 of the limiting member 30 to be in an unengaged state (as shown in FIG. 7). The straight-line distance can be determined by the length of the long groove 210. Then, the handle 20 can be turned over along the pivot C, and the hook 22 can be kept away from the front side of the housing 10.

Referring to FIG. 4, the draw bar 21 further has a positioning groove 216 that is formed between the long groove 210 and the pulling and gripping portion 213 of the draw bar 21. The housing 10 can correspondingly have a block part 16, and the block part 16 can block movement of the draw bar 21, so that the draw bar 21 is in the unengaged state (as shown in FIG. 7, otherwise referred to as an unlocked state). Accordingly, when the operator feels that the handle 20 is blocked by the block part 16, the operator can know that the handle 20 has left the limiting member 30.

Referring to FIG. 4, FIG. 6, and FIG. 7, the block part 16 has a blocking bevel 164, the positioning groove 216 has a positioning bevel 2164, and the positioning bevel 2164 is close to the hook 22. When the hook 22 changes from the engaged state to the unengaged state, the blocking bevel 164 abuts against the positioning bevel 2164. In other words, when the handle 20 slides along the unlocking direction D2 until the positioning bevel 2164 abuts against the block part 16, the hook 22 of the handle 20 is in the unlocked state.

Referring to FIG. 4, the following description describes further details of the hook 22. The hook 22 has a top wall 221, a pair of side walls 222, and a rear wall 224. The pair of side walls 222 is connected to two sides of the top wall 221. The rear wall 224 is connected to the rear end of the pair of side walls 222 and is close to the draw bar 21. Each of bottoms of the pair of side walls 222 has an inner rail 223 that extends inward, and each of inner sides of the pair of side walls 222 is recessed to form a guide groove 2220. Specifically, the guide groove 2220 is located between the inner rail 223 and the top wall 221. Moreover, each of both sides of the limiting member 30 of the housing 10 has a limiting recessed portion 31, and the inner rail 223 can be slidably disposed in the limiting recessed portion 31. When the hook 22 is in the engaged state, the rear wall 224 abuts against the limiting member 30. When the inner rail 223 slides into the limiting recessed portion 31 of the limiting member 30, the handle 20 can be prevented from being displaced outwardly in the extraction direction. That is, the handle 20 is prevented from moving in the X-axis direction of FIG. 1 and FIG. 4.

In addition, as shown in FIG. 3, an observation window 2210 is formed on the top wall 221 of the hook 22, and a top portion of the limiting member 30 is exposed from the observation window 2210. In other words, different positions of the limiting member 30 can be seen through the observation window 2210. Accordingly, the operator can easily observe whether the handle 20 is in the engaged state, or has completely reached the unengaged state.

Referring to FIG. 4, the limiting recessed portion 31 further has a front blocking convex portion 311 and a rear blocking convex portion 312, the front blocking convex portion 311 is close to one of two ends of the limiting recessed portion 31, and the rear blocking convex portion 312 is close to another one of the two ends of the limiting recessed portion 31. Moreover, the inner rail 223 has a first positioning recessed hole 2231 and a second positioning recessed hole 2232, and the second positioning recessed hole 2232 is located in front of the first positioning recessed hole 2231. That is to say, the second positioning recessed hole 2232 is close to a free end of the hook 22.

Referring to FIG. 6, when the hook 22 is in the engaged state, the rear blocking convex portion 312 of the limiting member 30 is engaged into the first positioning recessed hole 2231 of the hook 22, so as to prevent the handle 20 from sliding. When the operator unlocks the hook 22, a tactile feedback can be provided by cooperation between the second positioning recessed hole 2232 and the rear blocking convex portion 312.

Referring to FIG. 7, when the hook 22 is in the unengaged state, the inner rail 223 of the hook 22 is completely separated from the limiting recessed portion 31 backwards. That is to say, the hook 22 is separated from the rear blocking convex portion 312 and is no longer restricted from moving, and the handle 20 can be freely turned outwards.

Referring to FIG. 7 and FIG. 8, the draw bar 21 has a rotation positioning block 218, and the rotation positioning block 218 protrudes outward from a top surface of the pivot end 211 (as shown in FIG. 1). When the operator continues to push the rotation positioning block 218 backward along the unlocking direction D2, the draw bar 21 can be turned over a predetermined angle (e.g., the predetermined angle in the present embodiment is 90°) along the pivot C, so that the hook 22 is away from the front side of the housing 10 and the operator can pull the handle 20 (or the draw bar 21) to extract the extraction device 100 from the electronic device 9. It is worth noting that the rotation positioning block 218 has another auxiliary function, and the another auxiliary function is that the rotation positioning block 218 can be blocked on the housing 10 when the draw bar 21 rotates along the pivot C by the predetermined angle, so as to prevent the draw bar 21 from being over-rotated (as shown in FIG. 8).

Referring to FIG. 9, the longitudinal direction of the handle 20 is parallel to the extraction direction, which is convenient for the operator to pull out the extraction device 100 from the notch 902 of the electronic device 9, allowing the extraction device 100 to depart from the receiving groove 901 of the main body 90. At this time, the hook 22 in the present embodiment is located at the front end of the handle 20 and has completely left the limiting member 30, such that the hook 22 will not be accidentally hit by the notch 902 of the electronic device 9.
