Description

Technical Field

[0001] This invention relates to a cable management device, and more particularly to a cable management device with adjustable angles in two orthogonal directions. Background Technology

[0002] When using a wired mouse, the user may experience reduced gliding feel due to the tension of the mouse cable. Existing technology provides cable management modules that fix the mouse cable to an elastic body, which then cushions the tension of the cable, thereby maximizing mouse performance.

[0003] However, in existing technologies, cable management modules are typically placed on a desktop, with the distance and angle of the elastomer relative to the desktop fixed. Users find it difficult to adjust the elastomer based on the placement of the display device, mouse, or their usage habits, resulting in the elastomer's buffering range not adequately adapting to the mouse cable's movement trajectory. Therefore, designing cable management devices that can adjust the elastomer's buffering range to suit different users has become a current research topic. Utility Model Content

[0031] Certain terms are used in the specification and claims to refer to specific elements. It will be understood by those skilled in the art that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to".

[0032] The following embodiments and accompanying drawings illustrate implementations of the present invention. Throughout this specification, the same element symbols denote the same elements. It should be understood that when an element is referred to as being "on" or "connected" to another element, it may be directly on or connected to the other element, or there may be intermediate elements present. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intermediate elements present. As used herein, "connection" may refer to a physical and / or electrical connection. Furthermore, "electrical connection" or "electrical coupling" indicates that intermediate elements may be present.

[0033] The directional terms used herein are for detailed description and not intended to limit the invention. For example, "upper" and "lower" are merely used to describe the relative positions of elements in the drawings, depending on the specific orientation of the drawings. Furthermore, ordinal numbers such as "first," "second," and "third" used in the specification are for modifying elements and do not inherently imply any prior ordinal number for that element, nor do they represent the order of one element with another, or the order of manufacturing processes. The use of these ordinal numbers is solely to clearly distinguish one element with a certain name from another element with the same name.

[0034] Please see Figure 1 and Figure 2 These are three-dimensional structural schematic diagrams of a cable management device 1 according to an embodiment of the present invention from different perspectives. The cable management device 1 is configured on a base 2. The cable management device 1 includes a first rotary joint assembly 11, a crossbar 14, a second rotary joint assembly 12, and a cable management assembly 13. The first rotary joint assembly 11 is rotatably connected to the base 2 about a first axis s1, the crossbar 14 is disposed on the first rotary joint assembly 11, and the second rotary joint assembly 12 is rotatably connected to the crossbar 14 about a second axis s2. The first axis s1 and the second axis s2 are orthogonal. The cable management assembly 13 is connected to the second rotary joint assembly 12. The cable management assembly 13 includes an elastic rod 132, on which a cable clip 133 is disposed. The cable clip 133 is used to clamp the cable (not shown in the figure). In this embodiment, the cable is a mouse cable, but it is not limited thereto. In a preferred embodiment, the elastic rod 132 is a silicone rod, a snake tube, or a spring rod, etc.; and, in this embodiment, there are two elastic rods 132, which are symmetrically distributed relative to the cable clip 133; however, the actual application is not limited to this.

[0035] In this embodiment, as Figure 1 and Figure 2As shown, the cable clip 133 has an arc-shaped slot for holding the cable (mouse cable). The diameter of this arc-shaped slot can correspond to the size of the mouse cable to fix it in place. Alternatively, the arc-shaped slot can also have ribs for fixing the mouse cable, but the actual application is not limited to this. It should be noted that when the mouse cable is held by the cable clip 133, the cable clip 133 will move synchronously with the mouse cable when the mouse slides on the desktop. This causes the elastic lever 132 to be driven and deform in the direction of mouse movement. When the mouse is used with a small sliding range, the elastic lever 132 can swing slightly with the direction of mouse movement without affecting the normal use of the mouse. When the mouse slides too far or is pulled too hard, the rebound force of the elastic lever 132 can provide a buffer against the large swing of the mouse cable, which is conducive to the rapid return of the mouse cable to its original position, making subsequent mouse movement smoother.

[0036] Thus, the first rotary joint assembly 11 and the second rotary joint assembly 12 of the cable management device 1 can rotate at any angle around two orthogonal axes (i.e., the first axis s2 and the second axis s2), thereby enabling the cable management assembly 13 to move freely within a certain range. In other words, when the position of the base 2 relative to the desktop is fixed, the elastic rod 132 and the cable clip 133 can also be adjusted to different angles or positions relative to the base 2 around the two rotation axes to adapt to different mouse placement positions and different user habits.

[0037] In a preferred embodiment, such as Figures 1 to 3 As shown, a first screw 115 passes through the first rotary joint assembly 11 and is locked to the base 2, so that the first rotary joint assembly 11 is rotatably connected to the base 2 around the first axis s1. In this embodiment, the first rotary joint assembly 11 includes a first connector 111 and a second connector 112. The first connector 111 and the second connector 112 are respectively provided with a first through hole 111h and a second through hole 112h corresponding to their positions. The first screw 115 passes through the second through hole 112h and the first through hole 111h in sequence and is locked to the base 2. That is, the first connector 111 and the second connector 112 are spliced ​​together and confined between the nut portion of the first screw 115 and the base 2, and can rotate with the first screw 115 as the rotation axis. Preferably, the first connector 111 and the second connector 112 can also be further reinforced by snap-fit, screw locking, adhesive, etc., but this is not a limitation. In other embodiments, the first rotary joint assembly 11 may also be rotatably connected to the base 2 via a universal joint with a rotating ball joint or other structure, and is not limited thereto.

[0038] Better, such as Figure 2 and Figure 3As shown, the surface of the first rotary joint assembly 11 facing the base 2 is provided with an anti-slip pad 11r. When the first screw 115 is fastened to the first rotary joint assembly 11 and the base 2, the anti-slip pad 11r contacts the base 2 to increase the frictional force of the first rotary joint assembly 11 relative to the base 2 during rotation, and also to prevent the first rotary joint assembly 11 from rubbing against each other when rotating relative to the base 2. In this embodiment, the anti-slip pad 11r protrudes from the first joint member 111 near the first through hole 111h (in a semi-circular shape and protruding from the periphery of the first through hole 111h), but is not limited thereto. The anti-slip pad 11r can be made of a soft material such as rubber. In other embodiments, the surface of the first joint member 111 facing the base 2 may also have multiple protrusions to increase the rotational frictional force, but the actual application is not limited to this.

[0039] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the first rotary joint assembly 11 has a slot 11s extending along a first direction (in this embodiment, the first direction is the second axial direction s2, but not limited thereto). A crossbar 14 is slidably inserted into the slot 11s to further expand the adjustability range of the cable management assembly 13. That is, in this embodiment, the crossbar 14 extends along the second axial direction s2 and is inserted into the slot 11s in a direction parallel to its extension direction (i.e., the second axial direction s2). The crossbar 14 can slide relative to the first rotary joint assembly 11 along the second axial direction s2. In some preferred embodiments, such as... Figure 1 and Figure 2 As shown, the crossbar 14 is rectangular, and the second rotary joint assembly 12 can be correspondingly connected to the first end 14t of the crossbar 14 to achieve rotation around the second axis s2; in some other preferred embodiments, the crossbar 14 can also be cylindrical, and the second rotary joint assembly 12 can be sleeved on the crossbar 14, or the second rotary joint assembly 12 can also be fixed to the crossbar 14, and the second rotary joint assembly 12 can be driven to rotate around the second axis s2 by the rotation of the crossbar 14 itself; however, the actual application is not limited to this.

[0040] In this embodiment, as Figures 1 to 3 As shown, the slot 11s is formed by splicing the first connector 111 and the second connector 112 together. Preferably, the first connector 111 is C-shaped, and the shape of the second connector 112 corresponds to the C-shape. The opening of the first connector 111 is plate-shaped, C-shaped, or other suitable shape, and is not limited thereto. In some other embodiments, the first rotary joint assembly 11 may also be integrally formed, and the slot 11s is formed through the middle of the first rotary joint assembly 11; however, practical applications are not limited to this.

[0041] In some preferred embodiments, such as Figure 3As shown, the first rotary joint assembly 11 further includes a receiving cavity 112s, in which a magnetic element 113 is disposed, and the crossbar 14 is correspondingly made of a magnetic material to increase the frictional force of the crossbar 14 sliding relative to the first rotary joint assembly 11. The magnetic element 113 is, for example, a magnet; the magnetic material is, for example, an iron-containing metal, a cobalt-containing metal, or a nickel-containing metal; but is not limited thereto. In some embodiments, the receiving cavity 112s communicates with the slot 11s, and a damping layer 141 is attached to the surface of the crossbar 14 facing the receiving cavity 112s; in other embodiments, the receiving cavity 112s and the slot 11s are not connected, and at least one of the first surface of the crossbar 14 and the second surface of the first rotary joint assembly 11 has a damping layer 114 / 141, with the first surface facing the second surface, but practical applications are not limited to this. In this embodiment, a first damping layer 114 is attached to the first surface of the crossbar 14, and a receiving cavity 112s is formed inward from the second surface of the first rotary joint assembly 11, with a second damping layer 141 attached to the second surface. The first damping layer 114 and / or the second damping layer 141 can be made of a polyester film (Mylar) material. This polyester film material has high surface flatness and good mechanical flexibility, ensuring that the resistance experienced by the crossbar 14 when sliding relative to the first rotary joint assembly 11 remains at the same level. This facilitates smooth sliding of the crossbar 14 and prevents the crossbar 14 from rubbing against the magnetic component 113 during sliding, but is not limited to this. In some preferred embodiments, the first rotary joint assembly 11 further includes a receiving cavity 112s, in which a damping element (not shown in the figure) is disposed. This damping element protrudes toward the crossbar 14 and is interference-fitted with the crossbar 14 to increase the frictional force of the crossbar 14 sliding relative to the first rotary joint assembly 11. This damping element can be, for example, a protrusion made of rubber material, or a spring sheet protruding toward the crossbar 14, but is not limited thereto. Preferably, the arrangement of the receiving cavity 112s and the damping layer is similar to the aforementioned cases and will not be described again.

[0042] In this embodiment, as Figure 3As shown, the magnetic element 113 or the damping element is installed in the receiving cavity 112s opened in the second connector 112. In other words, the magnetic element 113 or the damping element is installed in the second connector 112 located below the first connector 111, with the second surface located in the second connector 112, so that the magnetic element 113 or the damping element is in full contact with the first surface below the crossbar 14 to generate greater resistance. In other embodiments, the magnetic element 113 or the damping element may also be installed in the receiving cavity (not shown in the figure) opened in the first connector 111. In other words, the magnetic element 113 or the damping element is installed in the first connector 111 located above the first connector 111, with the second surface located in the first connector 111, so that the magnetic element 113 or the damping element is in contact with the first surface above the crossbar 14 to generate resistance. However, the actual application is not limited to this.

[0043] In a preferred embodiment, such as Figures 1 to 2 and Figures 4 to 5 As shown, the cable management assembly 13 includes a third rotary joint assembly 131, which is rotatably connected to the second rotary joint assembly 12 about a third axis s3 to further expand the adjustable range of the cable management clamp 133. The third axis s3 is orthogonal to the second axis s2.

[0044] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the elastic rod 132 is slidably inserted into the opening 130 of the third rotary joint assembly 131 along its extension direction. In this embodiment, the extension direction of the elastic rod 132 is perpendicular to the third axis s3, but it is not limited thereto. Preferably, cable clips 133 and limiting members 134 are fixed at opposite ends of the elastic rod 132, which can prevent the elastic rod 132 from slipping out of the third rotary joint assembly 131. In this way, the adjustable range of the cable clip 133 can be further expanded. By adjusting the sliding of the elastic rod 132, the length of the elastic rod 132 between the cable clip 133 and the third rotary joint assembly 131 can be adjusted, and the magnitude of the rebound force provided by the elastic rod 132 can also be adjusted accordingly, improving the user experience.

[0045] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the second rotary joint assembly 12 has a first receiving groove 12a and a second receiving groove 12b, the crossbar 14 has a first end 14t, and the third rotary joint assembly 131 has a second end 131t. The first end 14t and the second end 131t are rotatably engaged in the first receiving groove 12a and the second receiving groove 12b, respectively. The second receiving groove 12b can be connected to the first receiving groove 12a, or it can be independent of it; however, practical applications are not limited to this.

[0046] Preferably, the second rotary joint assembly 12 includes a third joint member 121 and a fourth joint member 122, the fourth joint member 122 being slidably disposed on the third joint member 121, and the third joint member 121 and the fourth joint member 122 together surrounding each other to form a first receiving groove 12a and a second receiving groove 12b. Specifically, a first end portion 14t is sandwiched between the third joint member 121 and the fourth joint member 122, and the surfaces of the third joint member 121 and the fourth joint member 122 corresponding to the sliding direction of the fourth joint member 122 respectively abut against the first end portion 14t; and a second end portion 131t is sandwiched between the third joint member 121 and the fourth joint member 122, and the surfaces of the third joint member 121 and the fourth joint member 122 corresponding to the sliding direction of the fourth joint member 122 respectively abut against the second end portion 131t. The third connector 121 has a threaded through hole 121h, and at least a portion of the fourth connector 122 is positioned corresponding to the inner side of the threaded through hole 121h. The second screw 123 is locked into the threaded through hole 121h and pushes against that portion of the fourth connector 122, so that the fourth connector 122 moves toward the direction close to the third connector 121 (in this embodiment, it is the opposite direction of the second axial direction s2, but not limited thereto), thereby causing the third connector 121 and the fourth connector 122 to clamp the opposite sides of the first end 14t and the second end 131t respectively for fixation (i.e., the opposite sides along the second axial direction s2 in this embodiment, but not limited thereto).

[0047] Preferably, the fourth connector 122 has a blind hole 122h corresponding to the threaded through hole 121h. After the second screw 123 is locked into the threaded through hole 121h, it extends into the blind hole 122h. By tightening the second screw 123, it can penetrate deeper into the blind hole 122h, so that the stud of the second screw 123 can push against the bottom of the blind hole 122h. The blind hole 122h can play an auxiliary limiting role, but the actual application is not limited to this.

[0048] In a preferred embodiment, such as Figure 4As shown, the first end portion 14t has a first part and a second part. The two opposite ends of the first part are respectively fixed to the crossbar 14 and the second part. The first part is columnar and extends along the second axial direction s2 together with the crossbar 14. The second part is radially expanded relative to the first part, for example, it is disc-shaped (the radial dimension is larger than that of the columnar first part) and is held by the third connector 121 and the fourth connector 122 (in this embodiment, the third connector 121 and the fourth connector 122 hold the second part along the axial direction of the first end portion 14t, but this is not a limitation). That is, the cross-section of the first end portion 14t is T-shaped, and the second part of the first end portion 14t can play a limiting role to keep it always in the first receiving groove 12a without falling out, but the actual application is not limited to this. In other embodiments, the first end portion 14t can also be a universal joint with a rotating ball joint or other structure to be rotatably connected to the second rotary joint assembly 12, and this is not a limitation.

[0049] In a preferred embodiment, such as Figure 5 As shown, the second end 131t has a first portion and a second portion. The two opposite ends of the first portion are respectively fixed to the third rotary joint assembly 131 and the second portion. The first portion is cylindrical and extends along the third axial direction s3. The second portion is radially expanded relative to the first portion of the second end 131t, for example, it is disc-shaped (the radial dimension is larger than the cylindrical first portion) and is held by the third connector 121 and the fourth connector 122 (in this embodiment, the third connector 121 and the fourth connector 122 hold the second portion radially along the second end 131t, but this is not a limitation). That is, the second end 131t is similar to the first end 14t, with a T-shaped cross-section. The second portion of the second end 131t can serve as a limiting function to keep it always in the second receiving groove 12b without falling out, but the actual application is not limited to this. In other embodiments, the second end 131t can also be a universal joint with a rotating ball joint or other structure to be rotatably connected to the second rotary joint assembly 12, and this is not a limitation.

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the base 2 is the outer shell of the display device, such as the front shell, rear shell, or middle frame of the display device. In this embodiment, the base 2 is the middle frame of the display device, but it is not limited thereto. That is, the middle frame of the display device has corresponding threaded holes for the first screw 115 to be fastened and connected. The cable management device 1 is installed at the middle frame of the display device, which can reduce the space occupied on the desktop. In other embodiments, the base 2 can also be other ornaments placed on the desktop, or the base 2 can also be part of the cable management device 1, but the actual application is not limited to this.
