The first assembly includes a first engaging portion and a second engaging portion. The first sliding member is slidably disposed in the second assembly. The first sliding member includes a first through hole and a first slot, wherein the first through hole is connected to the first slot. The first engaging portion is disposed in the first through hole. The second sliding member is slidably disposed in the second assembly. The second sliding member includes a second through hole and a second slot, wherein the second through hole is connected to the second slot. The second engaging portion is disposed in the second through hole. The first sliding member slides in a first direction and drives the second sliding member to slide in a second direction, so that the first engaging portion engages with the first slot, and the second engaging portion engages with the second slot, wherein the first direction is different from the second direction.

[0005] According to one embodiment, the chassis of the present invention includes a shell and an assembly structure. The assembly structure is arranged in the shell. The assembly structure includes a first assembly, a second assembly, a first sliding member and a second sliding member.

[0077] Before assembling the first assembly 10 and the second assembly 12, the operating member 20 is located Figure 2 , Figure 4 and Figure 5 At this time, the positioning portion 220 of the positioning member 22 is embedded in the second positioning hole 130 to position the first sliding member 14 at the unlocking position on the second assembly member 12. Then, the user can set the first assembly member 10 on the second assembly member 12. At this time, the first engaging portion 100 is set in the first through hole 140 through the first opening 120, the second engaging portion 102 is set in the second through hole 160 through the second opening 122, and the third engaging portion 104 is set in the third through hole 180 through the third opening 124, so that the first assembly member 10 is set on the second assembly member 12.

[0078] Then, the user can slide the operating member 20 in the first direction D1 to Figures 6 to 8The locking position shown. At this time, the first sliding member 14 will drive the second sliding member 16 to slide in the second direction D2 as the operating member 20 slides in the first direction D1, and drives the third sliding member 18 to slide in the third direction D3, so that the first engaging portion 100 engages with the first engaging groove 142, the second engaging portion 102 engages with the second engaging groove 162, and the third engaging portion 104 engages with the third engaging groove 182. The first direction D1 is different from the second direction D2, and the first direction D1 is also different from the third direction D3. In this embodiment, the first direction D1 is perpendicular to the second direction D2 and the third direction D3, and the second direction D2 is opposite to the third direction D3. In another embodiment, the first direction D1 may not be perpendicular to the second direction D2 and the third direction D3, depending on the actual application. When the first engaging portion 100 is engaged with the first engaging groove 142 , the positioning portion 220 of the positioning member 22 is embedded in the first positioning hole 128 to position the first sliding member 14 at a locking position on the second assembly member 12 .

[0079] In this embodiment, the first sliding member 14 may further include a first inclined surface 146 and a third inclined surface 148, wherein the first inclined surface 146 and the third inclined surface 148 are located at opposite sides of the first sliding member 14, and the first inclined surface 146 and the third inclined surface 148 are inclined in opposite directions. In addition, the second sliding member 16 may further include a second inclined surface 166, and the third sliding member 18 may further include a fourth inclined surface 186. Figure 5 As shown, when the first sliding member 14 , the second sliding member 16 and the third sliding member 18 are respectively disposed in the second assembly 12 , the second inclined surface 166 of the second sliding member 16 abuts against the first inclined surface 146 of the first sliding member 14 , and the fourth inclined surface 186 of the third sliding member 18 abuts against the third inclined surface 148 of the first sliding member 14 .

[0080] like Figure 5 and Figure 8 As shown, when the first sliding member 14 slides in the first direction D1, the second inclined surface 166 slides relative to the first inclined surface 146, thereby driving the second sliding member 16 to slide in the second direction D2 and compressing the first elastic member 30. In addition, Figure 5 The second elastic member 32 is in a compressed state, that is, Figure 5 The second elastic member 32 provides an elastic force to push the third sliding member 18 toward the third direction D3. Therefore, when the first sliding member 14 slides toward the first direction D1, the fourth inclined surface 186 slides relative to the third inclined surface 148 due to the elastic force provided by the second elastic member 32, thereby driving the third sliding member 18 to slide toward the third direction D3.

[0081] When the user wants to remove the first assembly 10 from the second assembly 12, the user can slide the operating member 20 in the fourth direction D4 to Figure 2 , Figure 4and Figure 5 At this time, the first sliding member 14 will slide the second sliding member 16 toward the third direction D3 as the operating member 20 slides toward the fourth direction D4, and will also drive the third sliding member 18 to slide toward the second direction D2, so that the first engaging portion 100 is disengaged from the first engaging groove 142, the second engaging portion 102 is disengaged from the second engaging groove 162, and the third engaging portion 104 is disengaged from the third engaging groove 182. When the first engaging portion 100 is disengaged from the first engaging groove 142, the positioning portion 220 of the positioning member 22 is embedded in the second positioning hole 130, so as to position the first sliding member 14 at the unlocking position on the second assembly 12. Then, the user can remove the first assembly 10 from the second assembly 12.

[0082] See also Fig. 9 , Fig. 9 FIG. 1 is a partial perspective view of an assembly structure 1' according to another embodiment of the present invention. The main difference between the assembly structure 1' and the above-mentioned assembly structure 1 is that the assembly structure 1' further includes a first rack 34, a second rack 36 and a gear 38. Fig. 9 As shown. The first rack 34 is connected to the first sliding member 14, and the second rack 36 is connected to the second sliding member 16. In addition, the first rack 34 and the second rack 36 are respectively meshed with the gear 38. When the first sliding member 14 slides in the first direction D1 or the fourth direction D4, the first rack 34 will drive the gear 38 to rotate, and the gear 38 will drive the second rack 36 to slide, thereby driving the second sliding member 16 to slide in the second direction D2 or the third direction D3. In other words, the present invention can replace the above-mentioned combination of the inclined surface and the elastic member with a combination of a rack and a gear, so that the first sliding member 14 can drive the second sliding member 16 to slide. Similarly, the present invention can also replace the above-mentioned combination of the inclined surface and the elastic member with a combination of a rack and a gear, so that the first sliding member 14 can drive the third sliding member 18 to slide.

[0083] See also Fig.10 , Fig.10 FIG. 1 is a partial perspective view of an assembly structure 1″ according to another embodiment of the present invention. The main difference between the assembly structure 1″ and the above-mentioned assembly structure 1 is that the assembly structure 1″ further includes a first rod 40, a second rod 42 and a linkage 44, such as Fig.10As shown. The first rod 40 is connected to the first sliding member 14, and the second rod 42 is connected to the second sliding member 16. In addition, the linkage 44 is rotatably connected to the first rod 40 and the second rod 42. When the first sliding member 14 slides in the first direction D1 or the fourth direction D4, the first rod 40 will drive the second rod 42 to slide via the linkage 44, and then drive the second sliding member 16 to slide in the second direction D2 or the third direction D3. In other words, the present invention can replace the above-mentioned combination of the inclined surface and the elastic member with the combination of the rod and the linkage, so that the first sliding member 14 can drive the second sliding member 16 to slide. Similarly, the present invention can also replace the above-mentioned combination of the inclined surface and the elastic member with the combination of the rod and the linkage, so that the first sliding member 14 can drive the third sliding member 18 to slide.

[0084] See also Fig.11 , Fig.11 FIG. 5 is a schematic diagram of a chassis 5 according to another embodiment of the present invention. Fig.11 As shown, the chassis 5 includes a shell 50 and the above-mentioned assembly structure 1. It should be noted that the assembly structure 1 can also be replaced by the above-mentioned assembly structure 1' or assembly structure 1". In this embodiment, the chassis 5 can be a chassis of a server, but is not limited to this. It should be noted that, Fig.11 The housing 50 shown is only schematically drawn, and the housing 50 is indicated by dotted lines. The assembly structure 1 of the present invention can be disposed in the housing 50 to form a chassis 5, and can be applied to various devices (eg, servers).

[0085] In summary, as long as the user slides the first sliding member, the first sliding member, the second sliding member and the third sliding member will simultaneously engage or disengage with the first engaging portion, the second engaging portion and the third engaging portion of the first assembly member in different directions. Thus, the user can conveniently and quickly disassemble the first assembly member and the second assembly member by sliding the first sliding member. It should be noted that when only the adjacent two sides of the first assembly member and the second assembly member need to be fixed, the third sliding member can be omitted in the present invention.
