Detailed Implementation

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0018] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0019] For ease of understanding and explanation, all terms are... Figure 1 The coordinate system shown in the figure indicates the directions as references. The first direction is the positive direction of the x-axis, the second direction is the positive direction of the y-axis, and the third direction is the positive direction of the z-axis. The positive direction of the x-axis is forward, and the negative direction of the x-axis is backward. The positive direction of the y-axis is right, and the negative direction of the y-axis is left. The positive direction of the z-axis is up, and the negative direction of the z-axis is down.

[0020] like Figures 1 to 7As shown, a chassis device 100 according to an embodiment of the present invention includes a housing 10, a cable management assembly 20, and a protective assembly 30. The housing 10 has at least one interface 11 on one side in a first direction, the interface 11 being used to connect cables. The cable management assembly 20 is disposed on the housing 10 and located on the same side of the housing 10 as the interface 11. The cable management assembly 20 includes at least one cable management component 21 for winding cables. The cable management component 21 includes a housing portion 211 and a winding portion 212. The housing portion 211 has a duct for winding cables. The housing 211 has an opening 2111 that communicates with the housing 211a. The winding part 212 can enter and exit the housing 211a through the opening 2111. The winding part 212 is used to wind cables. The protective assembly 30 includes a protective cover 31, which covers the periphery of the cable management assembly 20 and is located on one side of the interface 11. The protective cover 31 and the housing 10 enclose the protective cavity 311. The protective cover 31 has a through-hole 312 on the side of the protective cover 31 facing the interface 11, through which the cable can pass.

[0021] The number of cable management components 21 can be the same as the number of interfaces 11 provided in the housing 10, and each cable management component 21 corresponds to one interface 11. Of course, the number of cable management components 21 can also be greater or less than the number of interfaces 11, which is not limited here. The protective cover 31 can be movably connected to the housing 10. For example, the protective cover 31 can be rotatably connected to the housing 10, so that the protective cavity 311 can be opened or closed by flipping the protective cover 31 to facilitate the operation of the cable management components 21 in the protective cavity 311. Of course, the protective cover 31 can also be detachably connected to the housing 10 by means of magnetic connection, snap connection, etc. The clearance port 312 can be one or more. By setting at least one clearance port 312 on the side of the protective cover 31 facing the interface 11, the cable that is connected to the interface 11 can pass through the clearance port 312 into the protective cavity 311 to be wound and cooperate with the cable management component 20. Of course, the protective cover 31 can also be provided at a position such as the side away from the interface 11. The specific implementation method can be set according to actual needs, and is not limited here.

[0022] It is understood that the chassis device 100 of this utility model embodiment can wind and organize redundant cables through the winding portion 212 of the cable management component 21, and then limit the cables wound on the winding portion 212 within the receiving cavity 211a of the housing portion 211. Furthermore, the protective cover 31 of the protective component 30 can cover the periphery of the cable management component 20 and form a protective cavity 311 with the housing 10. The protective cover 31 has a through-hole 312 on the side facing the interface 11, allowing cables to pass through, thereby protecting the cable management component 20 and the cables wound on it. This configuration enables the chassis device 100 to perform cable organization and limiting functions, improving the ease of use of the chassis device 100.

[0023] Specifically, such as Figures 2 to 4 As shown, in this embodiment of the present invention, the housing portion 211 extends along a first direction. One end of the housing portion 211 is connected to the housing 10, and the other end is provided with an opening 2111. The outer peripheral surface of the housing portion 211 is provided with a wire passage 2112 that communicates with the accommodating cavity 211a, and the wire passage 2112 extends along the first direction to the end of the housing portion 211 away from the housing 10. The winding portion 212 is provided with a winding groove 212a for accommodating the cable in the circumferential direction, and the wire passage 2112 can communicate with the winding groove 212a that enters the accommodating cavity 211a.

[0024] In some embodiments, the cable management component 21 and the interface 11 can be arranged at intervals in a third direction, and the cable passage 2112 can be provided on the side of the housing portion 211 facing the interface 11. Wherein, by providing the cable passage 2112 communicating with the receiving cavity 211a on the outer peripheral surface of the housing portion 211, the cable wound on the winding groove 212a can extend out of the receiving cavity 211a through the cable passage 2112. Furthermore, by extending the cable passage 2112 along a first direction to the end of the housing portion 211 away from the housing 10, when the winding portion 212 enters and exits the receiving cavity 211a along the first direction through the opening 2111, the cable passing through the cable passage 2112 can move synchronously with the winding portion 212 without being obstructed by the housing portion 211.

[0025] like Figures 5 to 7As shown, the winding part 212 of this utility model embodiment includes a winding rod 2121, a first limiting plate 2122, and a second limiting plate 2123. The winding rod 2121 extends along a first direction and enters the receiving cavity 211a. The outer wall of the winding rod 2121 is spaced apart from the cavity wall of the receiving cavity 211a. The first limiting plate 2122 is disposed at the end of the winding rod 2121 facing the housing 10 and is arranged around the circumference of the winding rod 2121. The outer peripheral surface of 22 can be slidably connected to the cavity wall of the receiving cavity 211a; the second limiting plate 2123 is provided at the end of the winding rod 2121 away from the housing 10 and is arranged around the circumference of the winding rod 2121. The first limiting plate 2122 and the second limiting plate 2123 form a winding groove 212a. The outer diameter of the second limiting plate 2123 is larger than the inner diameter of the opening 2111 so that the limiting plate can stop on the side of the housing part 211 away from the housing 10.

[0026] Specifically, a first limiting plate 2122 and a second limiting plate 2123 are respectively provided at both ends of the winding rod 2121. The first limiting plate 2122 and the second limiting plate 2123 can form a winding groove 212a, so that the cable wound around the circumference of the winding rod 2121 can be limited by the winding groove 212a and will not detach from the end of the winding rod 2121. Furthermore, by making the outer diameter of the first limiting plate 2122 the same as the inner diameter of the accommodating cavity 211a, the outer peripheral surface of the first limiting plate 2122 can be slidably connected to the cavity wall of the accommodating cavity 211a. Thus, the cavity wall of the accommodating cavity 211a can be used to limit the first limiting plate 2122, thereby improving the motion stability of the winding part 212 when moving in the first direction. By making the outer diameter of the second limiting plate 2123 larger than the inner diameter of the opening 2111, the limiting plate can stop the winding part 212 on the side of the housing part 211 away from the housing 10 when it moves into the receiving cavity 211a. This can limit the movement of the winding part 212 in the first direction and prevent it from going too deep into the receiving cavity 211a of the housing part 211, making it inconvenient for the operator to remove.

[0027] like Figure 7As shown, the cable management assembly 20 of this embodiment further includes a guide portion 213 disposed within the accommodating cavity 211a. The guide portion 213 has an internally hollow cylindrical structure and extends along the first direction. One end of the guide portion 213 is connected to the housing 10, and the outer wall of the guide portion 213 is spaced apart from the cavity wall of the accommodating cavity 211a. The winding rod 2121 has a guide hole 2121a at one end facing the housing 10, and a guide rod 2121b is disposed within the guide hole 2121a. The outer wall of the guide rod 2121b is spaced apart from the inner wall of the guide hole 2121a. The guide portion 213 can be sleeved around the periphery of the guide rod 2121b and movably pass through the guide hole 2121a. With this configuration, the movement stability of the winding portion 212 when moving along the first direction can be further improved through the guiding cooperation between the guide portion 213 and the guide rod 2121b.

[0028] like Figures 5 to 7 As shown, in this embodiment of the present invention, the outer wall of the guide portion 213 and the inner wall of the guide hole 2121a are spaced apart. The cable management component 21 also includes a spring 214, which is disposed between the outer wall of the guide portion 213 and the inner wall of the guide hole 2121a. The opposite ends of the spring 214 in the first direction are respectively connected to the hole wall of the guide hole 2121a and the housing 10.

[0029] Specifically, when the operator pulls the winding portion 212 away from the housing 10 in the first direction, causing the winding portion 212 to disengage from the receiving cavity 211a through the opening 2111 of the housing portion 211, the spring 214 can elastically deform and accumulate elastic potential energy under the action of the winding portion 212. When the winding portion 212 is no longer pulled by the external force, the spring 214 can release the elastic potential energy and pull the winding portion 212 toward the housing 10, so that the winding portion 212 can be re-accommodated in the receiving cavity 211a through the opening 2111 of the housing portion 211. This configuration enables the automatic reset function of the winding portion 212, which is beneficial to improving the ease of use of the cable management assembly 20.

[0030] like Figures 2 to 5 As shown, the cable management assembly 20 of this utility model embodiment further includes at least one guide member 22. The guide member 22 includes a first main body 221 and a second main body 222. One end of the first main body 221 is connected to the housing 10, and the other end extends along a first direction. Each first main body 221 is disposed on the side of a cable passage 2112 facing the interface 11. The second main body 222 is disposed on the end of the first main body 221 away from the housing 10, and the outer diameter of the second main body 222 is larger than the outer diameter of the first main body 221.

[0031] The first main body 221 is positioned on the side of the housing 211 where the cable passage 2112 faces the interface 11. A cable can be wound around the first main body 221 to guide and organize the cable between the cable management component 21 and the interface 11. By making the outer diameter of the second main body 222 larger than that of the first main body 221, the cable wound around the first main body 221 can be confined between the second main body 222 and the housing 10, preventing the cable from slipping off the end of the first main body 221.

[0032] In some embodiments, the protective cover 31 of this utility model is rotatably connected to the housing 10 on the side away from the interface 11. The protective cover 31 is rotatably arranged around a second direction, which is perpendicular to the first direction. The protective component 30 also includes a support member 32. One end of the support member 32 is rotatably connected to the housing 10, and the other end can be engaged with the protective cover 31 to support the protective cover 31 after it is rotated open, thereby improving the ease of use of the protective component 30.

[0033] Optionally, in some embodiments, the outer wall of the protective cover 31 may be provided with a slot, and the end of the support member 32 may be provided with a locking block, thereby realizing the snap-fit ​​engagement between the protective cover 31 and the support member 32. Of course, the protective cover 31 and the support member 32 may also be detachably connected by means of magnetic attraction or other methods. The specific implementation can be set according to actual needs and is not limited here.

[0034] like Figures 3 to 5 As shown, the chassis device 100 of this utility model embodiment further includes a connecting component 40. The connecting component 40 includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 is located inside the protective cavity 311 and is provided on the side of the winding part 212 away from the housing 10. The first connecting part 41 is provided with a slide groove 411 extending along a third direction, which is perpendicular to the first direction and the second direction. The second connecting part 42 is located inside the protective cavity 311 and is connected to the inner wall of the protective cover 31. The second connecting part 42 and the slide groove 411 are arranged opposite to each other along the first direction and are slidably connected with the slide groove 411. The second connecting part 42 can move relative to the slide groove 411 along the third direction when the protective cover 31 rotates, and push against the first connecting part 41 along the second direction, so that the first connecting part 41 drives the winding part 212 to move along the first direction.

[0035] Specifically, since the first connecting part 41 is located on the side of the winding part 212 away from the housing 10, and the winding part 212 is slidably assembled to the housing part 211 along the first direction, the first connecting part 41 is limited to being movable only in the first direction. Meanwhile, the second connecting part 42 is located on the inner wall of the protective cover 31, and the protective cover 31 can rotate around the second direction. Therefore, when the second connecting part 42 rotates with the protective cover 31 around the second direction, it can simultaneously displace in both the first and third directions. This allows the second connecting part 42 to move along the slide groove 411 of the first connecting part 41, while simultaneously pushing against the first connecting part 41 along the first direction, thereby causing the first connecting part 41 and the winding part 212 to displace in the first direction. With this configuration, while rotating to open the protective cover 31, the winding part 212 can be disengaged from the receiving cavity 211a of the housing part 211 via the connecting assembly 40, facilitating the winding operation of the winding part 212 and improving the ease of use of the chassis device 100.

[0036] In some embodiments, multiple cable management components 21 may be provided, and the first connecting part 41 may be connected and cooperated with multiple cable management components 21 at the same time. Thus, while rotating to open the protective cover 31, the first connecting part 41 can simultaneously drive the winding part 212 of multiple cable management components 21 to move, thereby further improving the ease of use of the chassis device 100.

[0037] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment of the present invention, the slide groove 411 has a locking hole 4111 on at least one side of the groove wall in the second direction. The locking hole 4111 extends along the third direction. The second connecting part 42 has a locking block 421 on at least one side in the second direction. The locking block 421 is slidably fitted into the locking hole 4111. With this arrangement, the locking hole 4111 can limit and guide the locking block 421, thereby improving the stability of the fit between the first connecting part 41 and the second connecting part 42. Furthermore, when the second connecting part 42 rotates with the protective cover 31 around the second direction, it can simultaneously move in the first direction and the third direction, thereby allowing the second connecting part 42 to move along the slide groove 411 of the first connecting part 41 and simultaneously push against the wall of the locking hole 4111 in the first direction.

[0038] This utility model also proposes a computer, which includes a chassis device 100. The specific structure of the chassis device 100 is as described in the above embodiments. Since this computer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0039] The working process of this utility model is as follows: When it is necessary to organize the cable, the protective cover 31 of the protective component 30 can be opened first, and the protective cover 31 can be fixed by the support member 32. The connecting component 40 can drive the winding part 212 of the cable management component 21 to move during the opening of the protective cover 31, so that the winding part 212 is pulled out through the opening 2111 and at least partially exposed outside the housing part 211. At this time, the end of the cable with the plug can be inserted into the protective cavity 311 of the protective cover 31, and its redundant part can be wound around the winding rod 2121 of the winding part 212. After winding, the winding part 212 can be re-entered into the receiving cavity 211a of the housing part 211 through the opening 2111, and the cable can be passed through the cable passage 2112 of the housing part 211. Finally, the protective cover 31 and the winding part 212 can be reset. At this time, part of the cable wound on the winding part 212 can be limited in the receiving cavity 211a of the housing part 211, and the remaining cable can pass through the cable passage 2112 of the housing part 211 and the clearance opening 312 of the protective cover 31 in sequence, and connect with the interface 11 of the housing 10 through the plug interface 11. In this way, the redundant part of the cable can be sorted and limited, without affecting the normal connection between the cable and the interface 11.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
