[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0039] See Figures 1 to 3 In a first embodiment of the modular mounting device 100 of the present invention, the modular mounting device 100 is adapted to assemble a first electronic device 91 and a second electronic device 92 onto a display device 93. In this first embodiment, the first electronic device 91 is exemplified by a box PC, but is not limited thereto; the second electronic device 92 is exemplified by a power adapter, but is not limited thereto. The modular mounting device 100 is secured to the display device 93 by a plurality of screws 94. The first electronic device 91 is snapped onto the modular mounting device 100 by a plurality of screws 95. The second electronic device 92 is fixed to the modular mounting device 100 by a binding method. The first electronic device 91 and the display device 93 are located on opposite sides of the modular mounting device 100, and the first electronic device 91 and the second electronic device 92 are located on the same side of the modular mounting device 100.
[0040] The combined mounting device 100 includes a mounting bracket 1 for mounting the display device 93 and the first electronic device 91, a first functional bracket 2 for mounting the second electronic device 92, and a plurality of first fastening units 3. The first functional bracket 2 is detachably assembled and fixed to the mounting bracket 1 via the first fastening units 3.
[0041] For ease of subsequent explanation, we define the combined installation device 100 as having a left-right direction X, a vertical direction Y perpendicular to the left-right direction X, and a front-back direction Z perpendicular to both the left-right direction X and the vertical direction Y. Figure 2 The left and right directions X are defined as the direction the arrow points to (left) and the opposite direction (right). Figure 2The up-down direction Y refers to the direction indicated by the arrow as up, and the opposite direction as down. Figure 2 The forward and backward directions Z are defined as the direction indicated by the arrow as forward and the opposite direction as backward.
[0042] The mounting bracket 1 includes a mounting plate 11 and four recessed plates 12 recessed from the mounting plate 11. The recessed plates 12 are formed with a plurality of first mounting holes 121 spaced apart from each other. The mounting plate 11 is formed with a plurality of second mounting holes 111 spaced apart from each other and for the screws 95 to be fastened, four third mounting holes 112 spaced apart from each other, and a plurality of through holes 113 spaced apart from each other.
[0043] Each of the recessed plates 12 has two corresponding first mounting holes 121 spaced at an oblique angle. The first mounting holes 121 conform to the VESA mounting interface standard. In this first embodiment, the number of first mounting holes 121 is typically eight, with four of them conforming to a 100×100 mm spacing specification and the other four conforming to a 75×75 mm spacing specification. The number of screws 94 is typically four, each passing through one of the four corresponding first mounting holes 121 conforming to one of the aforementioned spacing specifications. However, the number of first mounting holes 121 is not limited to eight; for example, the number could be four or twelve, depending on requirements.
[0044] The second mounting hole 111 does not conform to the VESA mounting interface standard. Each of the second mounting holes 111 is used to secure the corresponding screw 95. Each of the second mounting holes 111 has a snap-fit hole portion 114 and a through hole portion 115 communicating with the top of the snap-fit hole portion 114. The width of the snap-fit hole portion 114 along the left-right direction X is smaller than the width of the through hole portion 115 along the left-right direction X. The through hole portion 115 is used for the corresponding screw 95 to pass through so that it is aligned with the snap-fit hole portion 114. The snap-fit hole portion 114 is used for the corresponding screw 95 to be secured. The number of second mounting holes 111 in this first embodiment is three as an example, but it is not limited thereto; the number of second mounting holes 111 can also be two or four.
[0045] The third mounting holes 112 do not conform to the VESA mounting interface standard. The third mounting holes 112 are arranged in a square. Each of the third mounting holes 112 is an elongated hole and its length extends along the vertical direction Y.
[0046] The perforations 113 are respectively located adjacent to the left and right opposite sides of the mounting plate 11. The number of corresponding perforations 113 adjacent to the left side or the right side of the mounting plate 11 is at least two and they are arranged at intervals along the vertical direction Y. Specifically, the number of corresponding perforations 113 adjacent to the left side of the mounting plate 11 is four, but not limited to this; the number of corresponding perforations 113 adjacent to the right side of the mounting plate 11 is two, but not limited to this.
[0047] The first functional bracket 2 includes a bracket body 21 and two straps 22 disposed on the bracket body 21. The bracket body 21 has four spaced-apart side holes 211 and a plurality of through holes 215 for the first fastening unit 3 to pass through. Two corresponding side holes 211 spaced apart along the left-right direction X are for one corresponding strap 22 to pass through. The through holes 215 are adjacent to the right side of the bracket body 21 and spaced apart along the up-down direction Y. The through holes 215 are respectively used to connect to the corresponding through holes 113 adjacent to the left side of the mounting bracket 1. The bracket body 21 is detachably assembled and fixed to the mounting bracket 1 by the first fastening unit 3. The side holes 211 in this first embodiment are illustrated as four, however, the number is not limited as long as the second electronic device 92 can be bound and fixed to the bracket body 21 by the straps 22. For example, the bracket body 21 may have one strap 22 and two side holes 211 for the strap 22 to pass through.
[0048] Each of the first fastening units 3 includes a screw 31 and a nut 32. The screw 31 passes through the corresponding through hole 113 of the mounting bracket 1 and the corresponding through hole 215 of the first functional bracket 2 and is screwed onto the nut 32 to lock the mounting bracket 1 and the first functional bracket 2 together.
[0049] When assembling the combined mounting device 100, the mounting bracket 1 and the first functional bracket 2 can be locked together by passing the screw 31 of each of the first fastening units 3 through the corresponding through hole 113 of the mounting bracket 1 and the corresponding through hole 215 of the first functional bracket 2 and screwing it into the nut 32.
[0050] See Figures 3 to 6To mount the first electronic device 91 and the second electronic device 92 onto the display device 93 using the combined mounting device 100, firstly, the combined mounting device 100 is secured to the display device 93 by inserting screws 94 through the corresponding first mounting holes 121 of the mounting bracket 1 and locking them into the multiple screw holes 931 of the display device 93, so that the mounting bracket 1 abuts against the display device 93 via the recessed plate 12. Next, after installing the screws 95 onto the first electronic device 91, the screws 95 are inserted into the through holes 115 of the second mounting holes 111 of the mounting bracket 1. Then, the screws 95 are moved downwards along the vertical direction Y from the through holes 115, so that the screws 95 are engaged with the engaging holes 114. If it is necessary to remove the first electronic device 91 from the mounting bracket 1 later, the operation can be reversed. Finally, the second electronic device 92 is placed against the support body 21 of the first functional support 2, and the straps 22 are passed through the side holes 211 of the first functional support 2 and wrapped around the second electronic device 92, so that the second electronic device 92 can be bound and fixed to the support body 21 of the first functional support 2.
[0051] The recessed plate 12 of the mounting bracket 1 allows the mounting bracket 1 to contact the display device 93 through multi-point contact, reducing the contact friction area between the mounting bracket 1 and the display device 93. Furthermore, each recessed plate 12 provides partial accommodating space for a corresponding screw 94, preventing the screw 94 from protruding from the mounting plate 11 and affecting the assembly of the first electronic device 91.
[0052] It should be noted that, in addition to being secured to the display device 93 by the screws 94, the mounting bracket 1 of this first embodiment can also be secured to a wall (not shown) or the bottom of a tabletop (not shown) by the screws 94.
[0053] See Figure 7 The combined mounting device 100 of this first embodiment is also suitable for mounting on a support rod 97 using two straps 96 respectively passing through the third mounting holes 112. By having each strap 96 pass through two corresponding third mounting holes 112 spaced apart along the left-right direction X and wrap around the support rod 97, the combined mounting device 100 can be bound and fixed to the support rod 97.
[0054] The mounting bracket 1 of this first embodiment can be assembled on the display device 93, the wall, the bottom surface of the table, or the support rod 97, thereby enabling the user to install the combined mounting device 100 in the required location as needed.
[0055] See Figures 8 to 10 This is a second embodiment of the combined installation device 100 of the present invention, and its overall structure is roughly the same as that of the first embodiment. The difference between the second embodiment and the first embodiment is that the first functional bracket 2 is a track mounting kit and includes a fixed buckle frame 23 and a sliding buckle frame 24 that is slidably connected to the fixed buckle frame 23.
[0056] The combined mounting device 100 is suitable for mounting the first electronic device 91 onto a track 98 via the first functional bracket 2.
[0057] The mounting bracket 1 further includes a central recessed plate 13 recessed within the mounting plate 11. The central recessed plate 13 has a plurality of through holes 131 for the first fastening unit 3 to pass through. The fixing buckle frame 23 has a plurality of through holes 231 for the first fastening unit 3 to pass through. The fixing buckle frame 23 is detachably assembled and fixed to the central recessed plate 13 by the first fastening unit 3.
[0058] To assemble the modular mounting device 100, the mounting bracket 1 and the first functional bracket 2 are secured together by passing the screws 31 of each of the first fastening units 3 through the corresponding through holes 131 of the central recessed plate 13 and the corresponding through holes 231 of the fixing clip frame 23, and screwing them onto the nuts 32. The recessed design of the central recessed plate 13 reduces the contact friction area between the mounting bracket 1 and the fixing clip frame 23. Furthermore, the central recessed plate 13 provides a nut 32 accommodating area, preventing the nut 32 from protruding from the mounting plate 11 and affecting the assembly of the first electronic device 91.
[0059] When the combined mounting device 100 is to be installed on the track 98, it is secured to the track 98 by the fixed buckle frame 23 and the sliding buckle frame 24, thus assembling and fixing the combined mounting device 100 onto the track 98. In this way, the first electronic device 91 can be fixed to the track 98 by the combined mounting device 100.
[0060] See Figures 11 to 13 This is a third embodiment of the combined installation device 100 of the present invention, and its overall structure is roughly the same as that of the first embodiment. The difference between the third embodiment and the first embodiment is that the first functional bracket 2 is another installation bracket with the same structure as the installation bracket 1.
[0061] The combined mounting device 100 is suitable for assembling the first electronic device 91 and the display device 93 onto a support base 99. The display device 93 and the support base 99 are located on opposite sides of the combined mounting device 100.
[0062] When assembling the combined mounting device 100, the screws 31 of each of the first fastening units 3 are inserted into the corresponding through holes 113 of the mounting bracket 1 and the corresponding through holes 113 of the first functional bracket 2, so that the mounting bracket 1 and the first functional bracket 2 can be locked together.
[0063] To assemble the display device 93, the first electronic device 91, and the support base 99 together using the combined mounting device 100, firstly, the screws 94 are inserted through the support base 99 and respectively through the corresponding first mounting holes 121 and screwed onto the display device 93 to secure the combined mounting device 100, the display device 93, and the support base 99 together. Then, the screws 95 (such as...) are... Figure 5 As shown, the first electronic device 91 can be fixed to the first functional bracket 2 by snapping it into the snap-fit hole 114 of the second mounting hole 111 of the first functional bracket 2.
[0064] See Figures 14 to 16 This is a fourth embodiment of the combined installation device 100 of the present invention, whose overall structure is largely the same as that of the first and second embodiments. The difference between the fourth embodiment and the first embodiment is that the combined installation device 100 further includes a second functional bracket 4 and a plurality of second fastening units 5. The second functional bracket 4 is detachably assembled and fixed to the installation bracket 1 through the second fastening units 5.
[0065] The combined mounting device 100 is suitable for assembling the first electronic device 91 and the second electronic device 92 on a track 98.
[0066] The mounting bracket 1 further includes a central recessed plate 13 recessed by the mounting plate 11. The central recessed plate 13 is formed with a plurality of through holes 131 for the second fastening unit 5 to pass through.
[0067] The second functional bracket 4 is a track-mounted kit, and its structure is the same as that of the first functional bracket 2 in the second embodiment. The second functional bracket 4 includes a fixed latching frame 41 and a sliding latching frame 42 slidably connected to the fixed latching frame 41. The fixed latching frame 41 has multiple through holes 411 for the second fastening unit 5 to pass through. The fixed latching frame 41 is detachably assembled and fixed to the mounting bracket 1 via the second fastening unit 5.
[0068] Each of the second fastening units 5 includes a screw 51 and a nut 52. The second fastening unit 5 locks the second functional bracket 4 onto the mounting bracket 1 by means of locking.
[0069] To assemble the second functional bracket 4 onto the mounting bracket 1, the screws 51 of each of the second fastening units 5 are passed through the corresponding through holes 131 of the central recessed plate 13 and the corresponding through holes 411 of the fixing clip frame 41, and screwed onto the nuts 52, thus securing the mounting bracket 1 and the second functional bracket 4 together. The recessed design of the central recessed plate 13 reduces the contact friction area between the mounting bracket 1 and the fixing clip frame 41. Furthermore, the central recessed plate 13 provides a nut 52 accommodating area, preventing the nut 52 from protruding from the mounting plate 11 and affecting the assembly of the first electronic device 91.
[0070] When the combined mounting device 100 is to be installed on the track 98, it is secured to the track 98 by the fixing buckle frame 41 and the sliding buckle frame 42, thus assembling and fixing the combined mounting device 100 onto the track 98. In this way, the first electronic device 91 and the second electronic device 92 can be assembled and fixed onto the track 98 by the combined mounting device 100.
[0071] See Figures 17 to 19 This is the fifth embodiment of the combined installation device 100 of the present invention, and its overall structure is roughly the same as that of the first and third embodiments. The difference between the fifth embodiment and the first embodiment is that the combined installation device 100 further includes a second functional bracket 4 and a plurality of second fastening units 5. The second functional bracket 4 is detachably assembled and fixed to the installation bracket 1 through the second fastening units 5.
[0072] The combined mounting device 100 is suitable for assembling the first electronic device 91, the second electronic device 92, and the display device 93 onto the support base 99. The display device 93 and the support base 99 are located on opposite sides of the front and rear of the combined mounting device 100.
[0073] The second functional bracket 4 is located on the side of the mounting bracket 1 opposite to the first functional bracket 2. The second functional bracket 4 is another mounting bracket with the same structure as the mounting bracket 1, and its structure is identical to that of the first functional bracket 2 in the third embodiment.
[0074] Each of the second fastening units 5 includes a screw 51 and a nut 52. The second fastening unit 5 locks the second functional bracket 4 onto the mounting bracket 1 by means of locking.
[0075] When the second functional bracket 4 is to be assembled onto the mounting bracket 1, the screw 51 of each of the second fastening units 5 passes through the corresponding through hole 113 of the mounting bracket 1 and the corresponding through hole 113 of the second functional bracket 4 and is screwed onto the nut 52, so that the mounting bracket 1 and the second functional bracket 4 can be locked together.
[0076] To assemble the first electronic device 91 onto the second functional bracket 4, the screws 95 (such as...) are... Figure 5 (As shown) They are respectively snapped into the snap-fit holes 114 of the second mounting holes 111 of the second functional bracket 4, so that the first electronic device 91 is fixed to the second functional bracket 4. In this way, the first electronic device 91, the second electronic device 92 and the display device 93 can be assembled and fixed on the support base 99 by the combined mounting device 100.
[0077] In summary, the combined installation device 100 of each embodiment can be detachably assembled and fixed to the installation bracket 1 by means of the first functional bracket 2 and the first fastening unit 3, so that the user can install different components and apply them to different environments by means of the installation bracket 1 and the first functional bracket 2, thus achieving the purpose of the present invention.
