The chassis cover plate fastening structure 1 is engaged with a pair of hooked members 283 in the chassis accommodating space 26 by hooking or separating to relatively cover the opening 27 of the chassis body 2.

[0051] The chassis cover plate fastening structure 1 has a chassis cover plate 11 and a sliding assembly S. The chassis cover plate 11 has a first side 111, a second side 112, a first end edge 113 and a second end edge 114. The first and second sides 111, 112 are arranged on opposite sides of the chassis cover plate 11, and the first and second end edges 113, 114 are arranged on opposite ends of the chassis cover plate 11. On the second side 112, the first end edge 113 is provided with a plurality of plug-in portions 1131 corresponding to the plug-in holes 231, the sliding assembly S is located at the second end edge 114, the second side 112 of the chassis cover plate 11 is corresponding to close the opening 27, and the plug-in portions 1131 are correspondingly inserted into the plug-in holes 231.

[0052] The sliding assembly S has a fixed base plate 13 and a sliding base plate 14, a pusher 15 and a pair of hook brackets 16. The fixed base plate 13 has a third side 131 and a fourth side 132. The third side 131 is attached to the second side 112 of the chassis cover 11. The fourth side 132 is provided with a pair of first studs 1321 and a plurality of first hook portions 1322. The sliding base plate 14 has a fifth side 141, a sixth side 142, a bent edge 143, a first through hole 144, a plurality of second hook portions 145 and a plurality of first springs 146 (such as Figure 6). The fifth and sixth sides 141, 142 are arranged on opposite sides of the sliding base plate 14, and the fifth side 141 is arranged on the fourth side 132 of the fixed base plate 13 so as to be relatively horizontally slidable. The bent edge 143 is bent toward the sixth side 142 at one end of the sliding base plate 14, and the first through hole 144 is adjacent to the other end of the sliding base plate 14. In one embodiment, the bent edge 143 can be provided with a handle 147, and when the chassis cover 11 corresponds to closing the opening 27, the bent edge 143 of the sliding base plate 14 is accommodated in the handle groove 241. The second hook portions 145 are arranged at the other end of the sliding base plate 14 corresponding to the first hook portions 1322 of the fixed base plate 13. One end of the first springs 146 is hooked on the first hook portions 1322 and the other end is hooked on the second hook portions 145.

[0053] The pusher 15 has a body 151 , a pair of flanges 152 , a plurality of first sidewalls 153 , a first receiving space 154 , a second stud 155 and a plurality of openings 156 . The push member 15 is disposed on the sixth side 142 of the sliding base 14. The pair of flanges 152 protrude outward from both sides of the body 151 corresponding to the hook brackets 16. The first side walls 153 extend from the edge of the body 151 toward the sliding base 14. The body 151 and the first side walls 153 jointly define the first accommodating space 154. The second stud 155 protrudes from the first accommodating space 154 toward the sliding base 14 corresponding to the first through hole 144. A screw lock element 157 is locked corresponding to the first through hole 144 and the second stud 155. One of the first side walls 153 of the push member 15 is provided with the opening 156 corresponding to the first and second hook buckle portions 1322, 145 of the fixed base 13 and the movable base 14.

[0054] like Figure 8As shown, the hook brackets 16 are disposed on the fourth side 132 of the fixed base plate 13 for hooking or separating with the hook receiving member 283. A receiving space 161 is defined between the pair of hook brackets 16, and the pushing member 15 is received in the receiving space 161. The pair of hook brackets 16 are pushed relative to the pushing member 15. The pair of hook brackets 16 also have a first end 162, a second end 163, a hook portion 164, a pivot hole 165, a second receiving space 166 and a torsion spring 167. The first and second ends 162 and 163 are disposed at opposite ends of the pair of hook brackets 16. The accommodation space 161 has a narrow end 1611 and an expanded end 1612. The accommodation space 161 is defined as gradually expanding from the second end 163 toward the first end 162. The hook portion 164 protrudes from the first end 162 toward a direction away from the accommodation space 161. The pivot hole 165 is disposed between the first and second ends 162 and 163. The pair of hook brackets 16 are respectively pivotally connected to the first studs 1321 of the fixed base plate 13 through the pivot holes 165. In this way, the hook bracket 16 uses the pivot hole 165 as a pivot center to make the first and second ends 162 and 163 swing up and down.

[0055] Furthermore, the second accommodation space 166 is a concave space and faces the fourth side of the fixed substrate 13. The torsion spring 167 is disposed in the second accommodation space 166 and has a first arm 1671 and a second arm 1672. The first arm 1671 extends toward the first end 162 and presses against the inner wall surface of the second accommodation space 166 adjacent to the accommodation space 161, and the second arm 1672 extends toward the second end 163 and presses against the inner wall surface of the second accommodation space 166 away from the accommodation space 161, so that the second arm 1672 of the torsion spring 167 applies force toward the accommodation space 161, and the first arm 1671 applies force toward the direction away from the accommodation space 161.

[0056] Please refer to Figures 9 to 11 , which are a three-dimensional schematic diagram of the support substrate, a sliding schematic diagram and a reset schematic diagram of the first embodiment of the chassis cover plate fixing structure of the present invention, and with reference to FIGS. 1, 3 and 4 at the same time, when the operator wants to operate the chassis cover plate fixing structure 1, the bending edge 143 of the sliding substrate 14 is pulled to make the sliding substrate 14 slide horizontally relative to the fixed substrate 13 in a direction away from the accommodating space 161, driving the flange 152 of the pushing member 15 to abut against the pair of hook brackets 16 (such as Fig.10 The second ends 163 of the pair of hook brackets 16 are pivotally moved along the pivot hole 165 away from the accommodating space 161, and the first ends 162 of the pair of hook brackets 16 are pivotally moved along the pivot hole 165 toward the accommodating space 161 (such as Fig.10 The first springs 146 are stretched.

[0057] In this embodiment, the chassis accommodating space 26 is provided with a supporting base plate 28 corresponding to the sliding assembly S of the chassis cover plate fixing structure 1. The supporting base plate 28 has a seventh side 281, an eighth side 282 and a pair of hook receiving members 283. The seventh side 281 is provided corresponding to the sixth side 142 of the sliding base plate 14. The pair of hook receiving members 283 are provided on the seventh side 281. The pair of hook receiving members 283 are provided with a first hook receiving hole 284 corresponding to the hook portion 164 of the pair of hook brackets 16. The hook portion 164 of the pair of hook brackets 16 is detachably hooked in the pair of first hook receiving holes 284. When the first end 162 of the pair of hook brackets 16 pivots and moves toward the accommodating space 161, the hook portion 164 of the pair of hook brackets 16 can be disengaged from the pair of first hook receiving holes 284, so that the chassis cover plate fixing structure 1 can be separated from the chassis body 2.

[0058] When the operator stops operating the chassis cover fastening structure 1, the bent edge 143 of the sliding base plate 14 is released. Since one end of the first springs 146 is hooked on the first hook portions 1322 of the fixed base plate 13 and the other end is hooked on the second hook portions 145 of the sliding base plate 14, the elastic force of the first springs 146 can force the sliding base plate 14 to slide horizontally relative to the fixed base plate 13 toward the accommodating space 161, driving the pushing member 15 to slide horizontally toward the accommodating space 161 and reset and no longer continue to press against the pair of hook brackets 16 (such as Fig.11 As the torsion spring 167 inside the pair of hook brackets 16 applies force, the second end 163 of the pair of hook brackets 16 pivots toward the accommodating space 161, and the first end 162 of the pair of hook brackets 16 pivots away from the accommodating space 161 (as shown in the arrow direction). Fig.11 At this time, the hook portions 164 of the pair of hook brackets 16 are hooked in the first hook receiving holes 284 of the pair of hook receiving members 283 again.

[0059] When the opening 27 of the chassis body 2 is to be covered, the plug-in portions 1131 of the chassis cover fixing structure 1 are first inserted into the corresponding plug-in holes 231 of the chassis body 2, and the hook portions 164 of the pair of hook brackets 16 are hooked into the first hook holes 284 of the pair of hook receiving members 283, thereby completing the combination of the chassis cover fixing structure 1 and the chassis body 2.

[0060] By means of the design of the present invention, the sliding base plate 14 slides horizontally relative to the fixed base plate 13 to drive the pushing member 15 to press against the pair of hook brackets 16, so that the pair of hook brackets 16 pivot and the hook portion 164 is separated from the hook receiving member 283, so that the chassis cover plate fixing structure 1 can be quickly disassembled and assembled on the chassis body 2 without tools, thereby saving disassembly and assembly time.

[0061] See also Figures 12 to 15 , is a three-dimensional schematic diagram of a fixed base plate, a three-dimensional schematic diagram of a sliding base plate, a three-dimensional schematic diagram of a pushing member and a sliding base plate limiting schematic diagram of a second embodiment of the chassis cover plate fixing structure of the present invention, and is supplemented by referring to Figures 1 to 11. As shown in the figure, some structures and functions of this embodiment are the same as those of the above-mentioned first embodiment, so they will not be repeated here. However, the difference between this embodiment and the above-mentioned first embodiment is that the fixed base plate 13 is further provided with a plurality of first limiting columns 1371, the sliding base plate 14 is further provided with a plurality of first limiting holes 1481, a second limiting hole 1482 and a plurality of buckle holes 1483, and the pushing member 15 is further provided with a second limiting column 1571 and a plurality of buckle feet 1572.

[0062] like Fig.12 and Fig.13 As shown, the first limiting posts 1371 are protrudingly arranged on the fourth side 122 of the fixed base plate 13, the first limiting holes 1481 are horizontal long holes with a length, and the first limiting posts 1371 pass through the first limiting holes 1481 accordingly. In this embodiment, the first limiting posts 1371 are represented as four, but not limited thereto. In other embodiments, the first limiting posts 1371 may also be represented as more than two first limiting posts 1371, and the number of the first limiting holes 1481 corresponds to the first limiting posts 1371. Thus, the horizontal sliding distance of the sliding base plate 14 can be limited to the length of the first limiting holes 1481 through the cooperation of the first limiting posts 1371 and the first limiting holes 1481.

[0063] like Fig.14 As shown, the second limiting column 1571 and the buckle feet 1572 protrude from the first accommodation space 154 of the pusher 15 toward the sliding base plate 14, and the second limiting hole 1482 is a circular hole (such as Fig.13), the second limiting column 1571 passes through the second limiting hole 1482, and the buckle feet 1572 pass through and buckle the buckle holes 1483. In this embodiment, the second limiting column 1571 is disposed at one end of the first accommodating space 154 away from the openings 156, but it is not limited thereto. In other embodiments, the second limiting column 1571 can be disposed at any position of the first accommodating space 154. In this embodiment, the buckle feet 1572 are provided in two and relatively protrude from the periphery of the second stud 155, but it is not limited thereto. In other embodiments, the buckle feet 1572 can also be provided in more than two and can be disposed at any position of the first accommodating space 154. Thus, the second limiting column 1571 and the second limiting hole 1482 can prevent the pusher 15 from rotating relative to the second stud 155 and the first through hole 144 of the sliding base plate 14, and the buckle legs 1572 and the buckle holes 1483 can further fix the pusher 15 and the sliding base plate 14 to each other.

As shown in the figure, some structures and functions of this embodiment are the same as those of the above-mentioned second embodiment, so they will not be repeated here. However, the difference between this embodiment and the above-mentioned second embodiment is that the fixed base plate 13 is further provided with a pair of third limiting columns 1372 and a pair of third limiting holes 138, and the pair of hook brackets 16 also have a fourth limiting column 168 respectively.

[0065] The pair of third limiting posts 1372 and the pair of third limiting holes 138 respectively correspond to the pair of first studs 1321. The pair of third limiting posts 1372 protrude toward the fourth side 132, and the pair of third limiting holes 138 are in the shape of crescent holes. The pair of fourth limiting posts 168 of the pair of hook brackets 16 protrude toward the fixed substrate 12 and pass through the pair of third limiting holes 138. The third limiting posts 1372 are respectively located above and below the hook brackets 16 near the second end 163 to limit the up and down swinging range of the hook brackets 16.

[0066] Thus, the pair of third limiting posts 1372 , the pair of third limiting holes 138 and the pair of fourth limiting posts 168 limit the pivoting range of the pair of hook brackets 16 around the pivot hole 165 .

[0067] See also Figures 19 to 20, is a perspective exploded schematic diagram and a perspective combined partial cross-sectional view of a protective cover of a fourth embodiment of the chassis cover plate fixing structure of the present invention, and is supplemented by referring to FIGS. 1 to 18. As shown in the figure, some structures and functions of this embodiment are the same as those of the first, second and third embodiments, so they will not be repeated here. However, the difference between this embodiment and the first, second and third embodiments is that the chassis cover plate fixing structure 1 further includes a protective cover 17 fixed to the fourth side 132 of the fixed base plate 13 and covers the sliding assembly S. The protective cover 17 has a protective plate body 171, a plurality of second 172 side walls, a pair of second hook holes 173 and an elongated hole 174.

[0068] The second side walls 172 extend from the edge of the protection plate body 171 toward the fixed base plate 12, the pair of second hook holes 173 are formed on the second side walls 172 corresponding to the hook portions 164 of the pair of hook brackets 16, and the hook portions 164 of the pair of hook brackets 16 are hooked at the second hook holes 173 of the protection cover 17 and the first hook holes 274 of the pair of hook members 283 at the same time, and the sixth side 142 of the sliding base plate 14 is provided with a columnar member 149 corresponding to pass through the elongated hole 174. In an alternative embodiment, the elongated hole 174 of the protection cover 17 and the columnar member 149 of the sliding base plate 14 can be omitted.

[0069] Thereby, the sliding assembly S can be protected by the protection cover 17 .

[0070] See also Figure 21 to Figure 25 , which is a three-dimensional schematic diagram of the limiting assembly of the fifth embodiment of the chassis cover plate locking structure of the present invention, a partial schematic diagram of the chassis rear plate, a limiting schematic diagram of the limiting assembly, a pressing schematic diagram of the limiting unit and a sliding schematic diagram, and is supplemented by reference to Figures 1 to 20 As shown in the figure, some structures and functions of this embodiment are the same as those of the first, second, third and fourth embodiments, so they will not be described here in detail. However, the difference between this embodiment and the first, second, third and fourth embodiments is that the chassis cover plate fixing structure 1 further includes a limiting component 18. The limiting component 18 has a plate body 181, a limiting plate 182, a pressure receiving portion 183, a limiting unit 184, a third hook portion 185, a second spring 186 and a plurality of fourth limiting holes 187.

[0071] The limiting plate 182 protrudes from one side of the plate body 181 toward the sliding assembly 13, and the limiting plate 182 has a notch 1821 corresponding to the columnar member 149. The pressure portion 183 protrudes from one end of the plate body 181 toward the opposite direction of the sliding assembly 13. The limiting unit 184 is provided with a pressing portion 1841 corresponding to the pressure portion 183. The third hook portion 185 protrudes from the other end of the plate body 181 along the axial direction of the plate body 181. The fourth limiting holes 187 are opened in the plate body 181.

[0072] The seventh side 281 of the support base plate 28 is provided with a plurality of columns 285 and a fourth hook portion 286. One end of the plate 181 adjacent to the pressure receiving portion 183 protrudes from the lower end of the support base plate 28. The columns 285 and the fourth hook portion 286 protrude toward the sliding base plate 14. One end of the second spring 186 is hooked on the third hook portion 185 and the other end is hooked on the fourth hook portion 286. The columns 285 pass through the fourth limiting holes 187. The rear plate 24 of the chassis body 2 is provided with a mounting hole 242, and the limiting unit 184 is correspondingly disposed in the mounting hole 242.

[0073] When the pressing portion 1841 of the limiting unit 184 does not press the pressed portion 183, the plate body 181 is suspended between the seventh side 281 of the supporting base plate 28 and the sixth side 142 of the sliding base plate 14 by the second spring 186, and the second spring 186 is not stretched. At this time, the notch 1821 of the limiting plate 182 does not correspond to the columnar member 149 of the sliding base plate 14. When the sliding base plate 14 is horizontally pulled away from the accommodating space 161, the horizontal sliding stroke of the sliding base plate 14 cannot be fully performed because the limiting plate 182 blocks the columnar member 149 of the sliding base plate 14, resulting in the hook portion 164 of the pair of hook brackets 16 being unable to escape from the first hook hole 284 of the hook receiving member 283, thereby restricting the chassis cover 11 from being separated from the chassis body 2.

[0074] When the pressing portion 1841 of the limiting unit 184 presses against the pressed portion 183 to drive the plate body 181 to move vertically downward relative to the sliding assembly 13, and the second spring 186 is stretched, the notch 1821 corresponds to the columnar member 149, and the sliding base plate 14 can be horizontally pulled away from the accommodating space 161. Since the notch 1821 of the limiting plate 182 allows the columnar member 149 to pass through, the horizontal sliding stroke of the sliding base plate 14 can be completely carried out, so that the hook portion 164 of the pair of hook brackets 16 can be disengaged from the first hook hole 284 of the hook receiving member 283, thereby the chassis cover 11 can be separated from the chassis body 2.

[0075] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
