In the present embodiment, the first component 50 is a base and the second component 52 is a cover. The second component 52 can be opened or closed relative to the first component 50. When the second component 52 is closed relative to the first component 50, a cable management space S is defined by the first component 50 and the second component 52. The cable management space S is configured to accommodate cables (not shown in figures) of the carried object 24. The function of the cable management device is well known to those skilled in the art. Therefore, no further illustration is provided.
The first component 50 comprises a wall 54. In the present embodiment, the first component 50 further comprises a bottom part 56 and a connection part 58. Each of the wall 54 and the connection part 58 is bent relative to the bottom part 56 to from a predetermined angle therebetween. In particular, the wall 54, the bottom part 56 and the connection part 58 can form a U-shaped structure. The shape the first component 50 is illustrated as an example, the present invention is not limited thereto. Each of the cable management devices 44 is connected (such as engaged) with the first arm 40 or the second arm 42 through a plurality of engaging features arranged on the connection part 58 of the first component 50.
The second component 52 is pivoted relative to the first component 50. For example, the second component 52 is pivoted to the connection part 58 of the first component 50 by a shaft 60.
As shown in FIG. 8, the second component 52 comprises a first part 62 and a second part 64. Preferably, the second part 64 is bent relative to the first part 62 and extended toward the bottom part 56. Wherein, the second component 52 further comprises at least one auxiliary part 66. In the present embodiment, the second component 52 further comprises two auxiliary parts 66 arranged on the first part 62. Wherein, the two auxiliary parts 66 are protruded from the first part 62 and extended toward the bottom part 56. A protrusion direction of the two auxiliary parts 66 relative to the first part 62 is substantially identical to a bending direction of the second part 64 relative to the first part 62.
As shown in FIG. 9, the wall 54 of the first component 50 of the cable management device 44 has a first side 68 a and a second side 68 b. Preferably, the second side 68 b is opposite to the first side 68 a. Preferably, the auxiliary part 66 comprises a first guiding section 70. The first guiding section 70 has an inclined surface or a curved surface. On the other hand, the first side 68 a of the wall 54 of the first component 50 is formed with a first engagement part 72. The second component 52 comprises a second engagement part 74. The second engagement part 74 is arranged on the second part 64 of the second component 74. Preferably, at least one of the first component 50 and the second component 52 has a second guiding section 76. In the present embodiment, each of the first engagement part 72 of the first component 50 and the second engagement part 74 of the second component 52 has the second guiding section 76. Wherein, the second guiding section 76 has an inclined surface or a curved surface.
As shown in FIG. 9 to FIG. 11, during a process of closing the second component 52 relative to the first component 50 along a first direction D1, the second engagement part 74 of the second component 52 is guided by the two second guiding sections 76 to be engaged with the first engagement part 72 of the first component 50. On the other hand, the first guiding section 70 of the auxiliary part 66 of the second component 52 contacts the second side 68 b of the wall 54 of the first component 50 such that the first guiding section 70 can provide a guiding effect during the process of closing the second component 52 relative to the first component 50.
As shown in FIG. 11, when the second component 52 is in a closed state relative to the first component 50, the second engagement part 74 of the second component 52 is engaged with the first engagement part 72 of the first component 50, and the auxiliary part 66 is located adjacent and corresponding to the second side 68 b of the wall 54 of the first component 50. Specifically, in the closed state, the wall 54 of the first component 50 is engaged between two portions (such as the second engagement part 74 and the auxiliary part 66) of the second component 52. In other words, arrangement of the auxiliary part 64 of the second component 52 can prevent the first engagement part 72 and the second engagement part 74 from being freely (or unintentionally) disengaged from each other due to the wall 54 of the first component 50 being pressed by a force F inwardly.
As shown in FIG. 12 and FIG. 13, when the second component 52 is in the closed state relative to the first component 50, a first distance L1 is defined between the auxiliary part 66 and the second side 68 b of the wall 54 of the first component 50. On the other hand, a second distance L2 (such as an engagement distance) is defined between a front end of the first engagement part 72 and a front end the second engagement part 74. Wherein, the first distance L1 is smaller than the second distance L2. That is to say, when the wall 54 of the first component 50 is pressed by the force F inwardly, the wall can be flexibly bent inwardly only within the first distance L1 due to blocking of the auxiliary part 66, such that a movable distance of the first engagement part 72 relative to the second engagement part 74 is smaller than the second distance L2. Therefore, the first engagement part 72 can be prevented from being disengaged from the second engagement part 74.
As shown in FIG. 14, in order to disengage the second component part 74 from the first engagement part 72, a user can open the second component 52 relative to the first component 50 along a second direction D2, so as to allow the second component 52 to be in an opened state relative to the first component 50 (refer to FIG. 9) for mounting or moving out the cables of the carried object 24.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
