[0034] In one aspect, FIGS. 1-5 show a server chassis 100 for mounting at least two computer servers to a server rack. The server chassis 100 includes a first housing 120 and a second housing 150 each configured to receive and enclose a computing device therein, e.g. a computer server, storage device, power supply and the like. The first housing 120 and the second housing 150 have the same physical dimensions and shapes e.g. in the embodiment as shown in the Figures, a hexahedron shape. The first housing 120 has a pair of first sidewalls 121 and 123 opposite to each other. Likewise, the second housing 150 has a pair of second sidewalls 154 and 156 opposite to each other. The first housing 120 and the second housing 150 are positioned with one of the first sidewalls, e.g. first sidewall 123 adjacent to and facing one of the second sidewalls, e.g. second sidewall 154. The other one of the first sidewalls, i.e. first sidewall 121 and the other one of the second sidewalls, i.e. second sidewall 156 are positioned away from each other, with the first sidewall 123 and the second sidewall 154 positioned between the first sidewall 121 and the second sidewall 156. For the purpose of directional and orientational reference of the parts and positional relationships in the context, an X-Y-Z coordinate system is defined and shown in the figures in which, the direction X-X is referred to as width direction, the direction Y-Y is referred to as depth direction, and the direction Z-Z is referred to as height direction.

[0035] Server chassis 100 includes a pair of first brackets 110, 130 and a pair of second brackets 140, 160. The first brackets 110, 130 are mounted to the first sidewalls 121, 123 of the first housing 120 by e.g. screws 117, 137, respectively. The second brackets 140, 160 are mounted to the second sidewalls 154, 156 of the second housing 150 by e.g. screws 147, 167, respectively.

[0036] As shown in FIGS. 6-9, the first bracket 130 is in the form of a pair of straight retaining bars each having a main portion 134 and a first engagement portion 136 formed integral to the main portion 134. The pair of retaining bars are mounted to the first sidewall 123 of the first housing 120, spaced apart from each other along the height direction Z-Z, and arranged parallel to each other and parallel to a depth direction Y-Y, forming a space 135 between the pair of first engagement portion 136. The main portion 134 is mounted to the first sidewall 123 of the first housing 120, and with the first engagement portion 136 positioned spaced apart from the first sidewall 123 of the first housing 120, forming a first groove 132 between the first engagement portion 136 and the first sidewall 120.

[0037] The second bracket 140 is in the form of a single piece of plate having a middle portion 144 and a pair of second engagement portions 146 formed integral to and at each one side of the middle portion 144. The second engagement portions 146 are positioned offset with respect to the middle position 144 such that upon the second bracket 140 being mounted to the second housing 150 and oriented parallel to the depth direction Y-Y, the middle portion 144 is in contact with the second sidewall 154 of the second housing 150. The second engagement portions 146 are positioned spaced apart from, and form a pair of second grooves 142 with respect to, the second sidewall 154 of the second housing 150.

[0038] The first bracket 130 and the second bracket 140 are so configured such that the second groove 142 is the same as or slightly greater than the thickness of the first engagement portion 136, and the first groove 132 is the same as or slightly greater than the thickness of the second engagement portion 146. The first housing 120, the second housing 150, the first bracket 130 and the second bracket 140 are made of rigid material such as steel, aluminum alloy or the like, with the strength and rigidity suitable for supporting computer servers and components to a server rack. Other rigid materials may also be used.

[0039] As shown in FIGS. 10-13, to assemble the first housing 120 and the second housing 150 to each other, the first housing 120 and the second housing 150 are placed with the first sidewall 123 and the second sidewall 154 adjacent to and facing each other. The second engagement portions 146 are brought into alignment with the first grooves 132 and meanwhile, the first engagement portions 136 are brought into alignment with the second grooves 142. The first housing 120 is then slid along an assembling direction 120a, which is parallel to the depth direction Y-Y, with respect to the second housing 150 during which, the second engagement portion 146 slid along and are inserted into the first grooves 132, and the first engagement portion 136 slid along and are inserted into the second grooves 142.

[0040] As shown in FIGS. 14-17, the server chassis 100 may further include a stopper in the form of e.g. a flange plate 148, which is connected to the second housing 150 and positioned at the end of the second bracket 140, such that upon the first housing 120 and the second housing 150 being positioned flush at the first and second end walls 1208, 1508 with respect to each other, the first housing 120 is brought into abutment against the flange plate 148 such that further sliding movement of the first housing 120 relative to the second housing 150 along the assembling direction 120a is prevented. The first housing 120 and the second housing 150 maybe secured to the flushed position by e.g. screws 149 fastening the flange plate 148 to the first housing 120.

[0041] Assembled in the above-illustrated manner, the second engagement portions 146 are fit into the first grooves 132 and meanwhile, the first engagement portions 136 are fit into the second grooves 142 the first housing 120, by which, the first housing 120 and the second housing 150 are jointed to each other, forming an integral structure. The engagement of the second engagement portions 146 with the first grooves 132, and the engagement of the first engagement portions 136 with the second grooves 142 allows the first housing 120 to slide relative to the second housing 150 along the depth direction Y-Y. In the meantime, the first housing 120 and the second housing 150 are prevented from separating apart from each other along the width direction X-X, the height direction Z-Z and any other angled direction A intersecting the depth direction Y-Y. Rotational movement of the second housing 150 relative to the first housing 120 is also prevented.

[0042] The sever chassis 100 is capable of supporting and mounting two computer servers (or other equipment) to a server rack, with one of the servers housed/fitted to the first housing 120 and the other one housed/fitted into the second housing 150, and with the first sidewall 121 and the second sidewall 156 secured to the rails 16 of the server rack 10.

[0043] As illustrated in FIGS. 18-21, upon being mounted to a server rack 10, the server chassis 100 is supported by the rack rails 16 at a first support point 120s at the first sidewall 121 and a second support point 150s at the second sidewall 156. The total load of the server chassis 100, depicted in FIG. 20 by a weight 120w of the first housing 120 and a computer server fitted therein, and a weight 150w of the second housing 150 and the computer server fitted therein, is borne by the first support 120s and the second support 150s along the height direction Z-Z. The bending moment 120m and 150m generated by the respective weight 120w and 150w, result in a compressive force 1201F/1501F and a tensile force 1203F/1503F exerting on the first housing 120 and the second housing 150. The compressive force 1201F/1501F act against each other at a position above the center axis 102 of the first housing 120 and the second housing 150. The tensile force 1203F/1503F act in a direction away from each other, at a position below the center axis 102.

[0044] With the second engagement portion 146 fitted in the first grooves 132 and the first engagement portion 136 fitted in the second grooves 142, the compressive force 1201F/1501F are borne by the upper second engagement portion 146a abutting against the first sidewall 123 of the first housing 120, and by the upper first engagement portion 136a abutting against the second sidewall 154 of the second housing 150. In the meantime, the tensile force 1203F and 1503F are borne by the lower second engagement portion 146b abutting against the lower first engagement portion 136b. As such, the first housing 120 and the second housing 150 are well fitted and secured to each other for supporting and mounting two computer servers to the server rack 10. Note that other equipment may also be fitted into the first housing 120 and/or second housing 150.

[0045] As shown in FIGS. 3, 18 and 19, the server chassis 100 may further include a first mounting bracket 110 fixed to the first sidewall 121 of the first housing 120, and a second mounting bracket 160 fixed to the second sidewall 156 of the second housing. The first mounting bracket 110 and the second mounting bracket 160 assist in the mounting operation of the server chassis 100 to a server rack 10.

[0046] As used herein, the singular a and an may be construed as including the plural one or more unless clearly indicated otherwise.
