[0109] In order to further illustrate the principle and structure of the present application, the preferred embodiments of the present application are now described in detail with reference to the accompanying drawings. However, the embodiments are only for illustration and explanation purposes and cannot be used to limit the scope of patent protection of the present application.

[0110] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. As used in this application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0111] Reference Figure 1A-1J , which shows the first embodiment of the extraction aid 100 according to the present application as a whole, and referring to Figure 2 , which shows an exploded view of the extraction aid 100. As shown in the figure, the main components of the extraction aid 100 include a housing 110, a handle 120, and a button 130. Furthermore, it may include one or more of a cover 140, an electromagnetic shielding member 150, a first elastic member 161, a second elastic member 162, a handle shaft 163, a button shaft 164, a light guide 165, a first fixing member 166, and a second fixing member 167.

[0112] The extraction aid 100 can be fixed to the object 400. The object 400 can be a server or a storage device of the server, but the present application is not limited thereto. In the present application, the direction in which the extraction aid 100 and the object 400 are connected to each other (i.e., Figure 1A The up and down directions in the figure can be referred to as the first direction, but the present application is not limited thereto.

[0113] Housing 110 can be secured to object 400 via a first securing member 166 and a second securing member 167. First securing member 166 can be a screw, a bolt, a rivet, or a stud. Second securing member 167 can also be a screw, a bolt, or a rivet. First securing member 166 and second securing member 167 can be the same or different.

[0114] The housing 110 may have an inner space. The housing 110 may have a pair of side walls 111. The side walls 111 may be formed with shaft holes 1111. In this embodiment, two shaft holes 1111 may be formed on each side wall 111. The front surface of one side of the housing 110 (ie, Figure 1A The head 112 may be formed on the upper surface of the housing 110. The handle 120 and the button 130 may be exposed on the front surface of the housing 110.

[0115] The handle 120 may be generally formed in a plate shape. The handle 120 may include a button engaging portion 122, an insertion abutment portion 124, and a withdrawal abutment portion 125. The button engaging portion 122 may be provided at one end of the handle 120, while the insertion abutment portion 124 and the withdrawal abutment portion 125 may be provided at the other end of the handle 120. The handle 120 may include a handle shaft mounting portion 123 through which a handle shaft 163 may pass, so that the handle 120 may pivot about the handle shaft 163. The handle shaft mounting portion 123 may be located on a side adjacent to the insertion abutment portion 124 and the withdrawal abutment portion 125. The insertion abutment portion 124 and the withdrawal abutment portion 125 may be formed as arms extending from the handle shaft mounting portion 123. The insertion abutment portion 124 and the withdrawal abutment portion 125 may be spaced a certain distance apart to accommodate a rod (not shown) on the bracket therebetween.

[0116] The distance between the button engaging portion 122 and the handle shaft 163 or the handle shaft mounting portion 123 is greater (e.g., several times greater) than the distance between the insertion abutment portion 124 and the handle shaft 163 or the handle shaft mounting portion 123. The distance between the button engaging portion 122 and the handle shaft 163 or the handle shaft mounting portion 123 is greater (e.g., several times greater) than the distance between the extraction abutment portion 125 and the handle shaft 163 or the handle shaft mounting portion 123. In this way, when the handle 120 is actuated near the button engaging portion 122, the actuation force can be amplified by the lever effect and transmitted to the insertion abutment portion 124 or the extraction abutment portion 125.

[0117] The handle 120 may have a through hole 121 formed therein. Specifically, the handle 120 may have a plurality of through holes 121 arranged linearly. The through holes 121 may be rectangular, but the present application is not limited thereto. The through holes 121 facilitate observation of the interior of the extraction aid 100 from the outside and facilitate heat dissipation from the object 400.

[0118] The rear side of the handle 120 (ie, Figure 1A The handle 120 may have a plurality of ribs 126. The plurality of ribs 126 may be formed along the third direction (ie, the lower side of the handle 120). Figure 1E The two members extend in an up-down direction in the middle and are spaced apart from each other and parallel to each other.

[0119] The button coupling portion 122 may be formed in a stepped structure receding relative to the front surface of the handle 120 .

[0120] See also Figure 2 and Figure 8BThe button 130 may include a handle engaging portion 131, a button shaft mounting portion 132, and a button elastic member abutting portion 133. The button shaft mounting portion 132 allows the button shaft 164 to pass through, allowing the button 130 to pivot about the button shaft 164. The button 130 can be pressed to rotate. The button 130 may be provided with an anti-slip portion 134 to increase the friction when pressing the button 130. The anti-slip portion 134 may be formed as a plurality of bar-shaped protrusions, but the present application is not limited thereto. The handle shaft 163 and the button shaft 164 may be parallel to each other.

[0121] See also Figure 1E 、 Figure 2 、 Figure 9B and Figure 10 The extraction aid 100 may further include a light guide 165. The light guide 165 may be used to transmit the light emitted by the light emitting portion 420 of the object 400 to the front of the extraction aid 100 (ie, Figure 9B (above). Housing 110 may include a channel 113 extending in a first direction. A light guide 165 may be disposed in channel 113. Light guide 165 may be an optical fiber. In this embodiment, light guide 165 is straight, thereby propagating light in a straight line and avoiding light loss due to bending. This straightness simplifies the processing of light guide 165 and the formation of channel 113.

[0122] The extraction aid 100 may further include a cover plate 140. The front end of the channel 113 (ie, Figure 9B The upper end shown in FIG. 1 blocks the light guide 165. The rear end of the channel (ie, Figure 9B The lower end (shown) of the channel 113 may be open. A cover plate 140 may cover the open lower end of the channel 113 to block the light guide 165. This allows the light guide 165 to be confined within the channel 113. The cover plate 140 may be light-transmissive to diffuse light emitted by the object 400 and prevent glare. The cover plate 140 may be formed as a flat plate for ease of processing and molding.

[0123] The front end of the channel 113 may have a first hole 116. The cover plate 140 may have a second hole 141. The first hole 116 and the second hole 141 are both aligned with the light guide 165. The first hole 116 and the second hole 141 are both smaller than the light guide 165, so that the light guide 165 does not pass through the first hole 116 or the second hole 141 and move out of the channel 113.

[0124] In this embodiment, the extraction aid 100 may include two light guides 165 and two channels 113. The number of light guides 165 may correspond to the number of channels 113. Accordingly, the cover plate 140 may cover both channels 113 and have two second holes 141. It should be noted that this application does not limit the number of light guides 165 and channels 113. Because the light guides 165 can be placed in separate channels 113, no additional components are required to secure or retain the light guides 165, thereby reducing the number of parts.

[0125] The extraction aid 100 may include an electromagnetic shielding member 150. The electromagnetic shielding member 150 contacts the object 400 and the support to conduct static electricity between the object 400 and the support. The electromagnetic shielding member 150, the object 400, and the support may all be made of conductive materials, such as metal. The support may be grounded. In this way, the object 400 can be grounded via the electromagnetic shielding member 150 and the support. The electromagnetic shielding member 150 may function to prevent electromagnetic radiation. The electromagnetic shielding member 150 may extend outside the housing 110.

[0126] See also Figure 2 and Figure 11 , the electromagnetic shielding member 150 may include a contact arm 151, a contact hole 152 and a wing 154. The contact arm 151 may be bent to have elasticity. A plurality of contact protrusions 153 extending toward the center of the contact hole 152 may be formed in the contact hole 152. The second fixing member 167 may pass through the contact hole 152. In other words, the contact hole 152 may be sleeved on the second fixing member 167. The plurality of contact protrusions 153 may contact the second fixing member 167. The contact arm 151 may be elastically connected to the bracket. The wing 154 may extend from both sides of the electromagnetic shielding member 150. The electromagnetic shielding member 150 and the second fixing member 167 may be made of a conductive material. In this embodiment, the electromagnetic shielding member 150 may be provided at one end of the housing 110, for example, Figure 6B In another embodiment, the electromagnetic shielding member 150 may be provided on both sides of the housing 110, for example, on both sides along the third direction, and the electromagnetic shielding member 150 may include a plurality of contact arms 151 that may extend along the second direction over the entire housing 110 or over most of the housing 110.

[0127] See also Figure 3 、 Figure 6A and Figure 6B, the housing 110 may include a positioning portion 114, and the first fixing member 166 may have a clamped portion 1661. When the extraction aid 100 is installed on the object 400, the first fixing member 166 is first fixed to the object 400 (at this time, the clamped portion 1661 is exposed outside the object 400), and then the extraction aid 100 is slid along the object 400 so that the positioning portion 114 contacts the clamped portion 1661. The positioning portion 114 may be formed as a U-shaped fork. Optionally, the positioning portion 114 may be formed in a Y-shape or a C-shape. When the extraction aid 100 slides to align with the object 400, the first fixing member 166 may engage with the positioning portion 114 to prevent the housing 110 from further moving relative to the object 400. At this time, the extraction aid 100 can still be moved relative to the object 400 along the Figure 6B However, since the positioning portion 114 is engaged with the first fixing member 166, the first fixing member 166 prevents the extraction aid 100 from moving in the first direction relative to the object 400. After the positioning portion 114 is engaged with the first fixing member 166, the second fixing member 167 can pass through the extraction aid 100 to fix the extraction aid 100 to the object 400.

[0128] See also Figure 2 and Figure 11 The housing 110 may have a first recess 1121 and a second recess 117. The first recess 1121 and the second recess 117 may be spaced apart along the first direction. The second fixing member 167 may extend from the first recess 1121 to the second recess 117. In other words, the second fixing member 167 may pass through the housing 110. The electromagnetic shielding member 150 may be partially located in the second recess 117, with the contact arms 151 of the electromagnetic shielding member 150 extending out of the second recess 117. The wings 154 may abut against the sidewalls of the second recess 117, thereby maintaining the stability of the electromagnetic shielding member 150 mounted on the second fixing member 167.

[0129] See also Figure 4A 、 Figure 4B 、 Figures 7A-8B , the first elastic member 161 can be arranged between the housing 110 and the handle 120. The second elastic member 162 can be arranged between the housing 110 and the button 130. The first elastic member 161 and / or the second elastic member 162 can be a torsion spring, but the present application is not limited thereto. The first elastic member 161 can be sleeved on the handle shaft mounting portion 123. The second elastic member 162 can be sleeved on the button shaft mounting portion 132. The first elastic member 161 can exert force on the handle 120. Figure 7B counterclockwise (i.e., Figure 7B and Figure 8B One end of the second elastic member 162 can abut against the button elastic member abutting portion 133 to apply force to the button 130. Figure 7B The counterclockwise force in .

[0130] When the extraction aid 100 and the object 400 are inserted into the bracket, the extraction aid 100 and the object 400 are in Figure 4A 、 Figure 7A and Figure 7B The state shown. At this time, the handle 120 is in the first pivot position and the button 130 is in the locked position. When the handle 120 is in the first pivot position and the button 130 is in the locked position, the handle 120 and the button 130 can be substantially flush with the head 112, thereby giving the extraction aid 100 a smooth appearance. The handle engaging portion 131 of the button 130 presses against the button engaging portion 122 of the handle 120, preventing the handle 120 from bouncing due to the force applied to it by the first elastic member 161.

[0131] When it is necessary to remove the object 400 from the bracket, the button 130 can be pressed to remove the object 400 from the bracket. Figure 7B The status shown changes to Figure 8B The state shown, that is, the button 130 is rotated clockwise so that the handle engaging portion 131 no longer blocks the button engaging portion 122 of the handle 120. Figure 8B As shown, the button 130 is in the unlocked position at this time.

[0132] See also Figure 5 、 Figure 9A and Figure 9B After pressing the button 130, the first elastic member 161 pushes the handle 120 in a counterclockwise direction (ie, Figure 9B The operator can then further apply a counterclockwise force to the handle 120 to actuate the handle 120 to a certain angle. Figure 5 and Figure 9B The button 130 is moved to the initial position (locking position) by the second elastic member 162 after the pressing force is released.

[0133] When the handle 120 rotates counterclockwise, the extraction abutment portion 125 also rotates counterclockwise and abuts against the rod on the bracket, thereby pushing the extraction aid 100 and the object 400 away from the bracket.

[0134] Continue to see Figure 5 、 Figure 9A and Figure 9B , in contrast to the above process, when the object 400 needs to be inserted into the bracket, the operator moves along Figure 9B When the handle 120 is rotated clockwise, the insertion abutment portion also rotates clockwise and abuts against the rod on the bracket, thereby pushing the extraction aid 100 and the object 400 into the bracket together.

[0135] When the handle 120 is close to the button 130, the first inclined surface 127 on the handle 120 cooperates with the second inclined surface 135 on the button 130, so that the button 130 overcomes the elastic force of the second elastic member 162 and rotates clockwise until the handle 120 rotates to the first pivot position, and the second elastic member 162 pushes the button 130 to rotate counterclockwise to lock the handle 120.

[0136] When the handle 120 is in the first pivot position, the first hole 116 is exposed through the through hole 121 of the handle 120. In other words, light emitted from the light emitting portion 420 of the object 400 is scattered by the cover plate 140 and transmitted through the second hole 141 on the cover plate 140 by the light guide 165. The light is then emitted to the front of the extraction aid 100 through the first hole 116 on the housing 110 and the through hole 121 of the handle 120.

[0137] Figures 12A to 13 The second embodiment of the present application is shown. The second embodiment of the present application will be described below, wherein the same parts as those of the first embodiment will be omitted to avoid repetition.

[0138] See also Figures 12A to 13 , the extraction aid 100 may include an extension portion 115. The extension portion 115 may be formed integrally with the housing 110 and extend laterally from the housing 110. Alternatively, the extension portion 115 may be formed separately from the housing 110 and fixed together. The front surface ( Figure 12E The surface shown in FIG4 may have a plurality of holes arranged in an array. These holes can provide better heat dissipation for the object 400. These holes can be in the shape of a regular hexagon, a circle, a rectangle, or a triangle. The extraction aid 100 of this embodiment can be applied to larger objects 400.

[0139] Figures 14A to 17C The third embodiment of the present application is shown. The third embodiment of the present application will be described below, wherein the same parts as those of the first embodiment will be omitted to avoid repetition.

[0140] See also Figures 14A to 15 The electromagnetic shielding member 150 may be located on both sides of the housing. The electromagnetic shielding member 150 may have a shape approximately equal to an isosceles triangle. The handle 120 may be exposed on the front surface of the housing 110 (ie, Figure 14A ), and the button may be exposed on the upper surface of the housing 110 (ie, Figure 14A In this embodiment, the handle 120 may have a bent shape.

[0141] The button 130 may have a spring arm 136 and a pivot portion 137 disposed at the end of each spring arm on either side. The pivot portion 137 may protrude outward from the spring arm 136. The pivot portions 137 on either side of the button 130 may be respectively positioned in corresponding holes on either side of the housing 110, allowing the button 130 to be pivotally connected to the housing 110. In this embodiment, due to the presence of the spring arm 136 and the pivot portion 137, the button 130 can be pivotally connected to the housing 110 without requiring an additional pivot, thereby reducing the number of parts.

[0142] In this embodiment, the second elastic member 162 may be a coil spring, with two ends thereof respectively abutting against the button 130 and corresponding inclined surfaces inside the housing 110 .

[0143] See also Figures 16A to 17C The handle 120 may have a hook-shaped button engaging portion 122 . The button 130 may have a handle engaging portion 131 that cooperates with the hook-shaped button engaging portion 122 .
