Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments may be combined with each other without collision.

In view of this, as shown in fig. 1 and 2, the embodiment of the present application provides a chassis, which can keep the gaps between the cover plate and the housing uniform, and improve the reliability of the cover between the cover plate and the housing. Hereinafter, an exemplary explanation will be given.

Referring to fig. 1, the present embodiment provides an electronic device 200, including a chassis 100.

Referring to fig. 2 and 3 in combination, the chassis 100 includes a housing 10 and a cover 30. The housing 10 defines a receiving cavity 14, the receiving cavity 14 being for mounting an electronic device 201. The electronic device 201 may be any one or more of a central processing unit, an image processor, a memory bank, and a power supply, and may be other electric devices. In the present embodiment, the housing 10 includes a bottom plate 11, a side plate 12, and a top plate 13, and the bottom plate 11, the side plate 12, and the top plate 13 together enclose a housing chamber 14 having an opening 15 along the first direction Y1. The top plate 13 and the bottom plate 11 are disposed at intervals in the second direction Y2. The second direction Y2 is perpendicular to the first direction Y1. The housing 10 further includes a connection plate 20, and the connection plate 20 is disposed on one side of the housing 10 along the first direction Y1. In the present embodiment, the connection plate 20 is connected to an edge of the top plate 13 along the first direction Y1. In other embodiments, the connection plate 20 may be connected to an edge of the side plate 12 along the first direction Y1, or an edge of the bottom plate 11 along the first direction Y1. The connection plate 20 is provided with positioning holes 21.

The cover plate 30 is covered on the opening 15, one side of the cover plate 30 facing the connecting plate 20 is provided with a clamping part 41, the clamping part 41 penetrates through the positioning hole 21 and is matched with the positioning hole 21, one end of the clamping part 41 away from the cover plate 30 is provided with a limiting part 42, and the limiting part 42 is located on one side of the connecting plate 20 away from the cover plate 30 so as to limit the cover plate 30 on the shell 10 in the first direction Y1. Specifically, referring to fig. 4 and 5, the cover 30, the engaging portion 41 and the limiting portion 42 together form a positioning slot 50 with an opening facing the bottom plate 11 along the second direction Y2, and the positioning slot 50 is engaged with the connecting plate 20, so that the cover 30 can be limited on the connecting plate 20 in the first direction Y1 by the engagement of the positioning slot 50 formed by the engaging portion 41, the limiting portion 42 and the cover 30 engaged with the connecting plate 20, so that the cover 30 and the connecting plate 20 are fixed along the gap of the first direction Y1, and further the mounting gap between the cover 30 and the housing 10 in the first direction Y1 is kept fixed, thereby ensuring uniformity of the mounting gap between the cover 30 and the housing 10, making the cover 30 not easy to bend in the first direction Y1, and improving the mounting reliability of the cover 30 and the housing 10.

In the present embodiment, the limiting portion 42 is a rib 42a protruding from the surface of the engaging portion 41 away from the top plate 13 along the second direction Y2. In other embodiments, the limiting portion 42 may be a rib 42a protruding from the engaging portion 41 along the first direction Y1 away from the end surface of the cover plate 30, and may extend along the second direction Y2.

In this embodiment, referring to fig. 5 and 7, the positioning hole 21 includes a receiving end 211 and a tightening end 212, the receiving end 211 is used to allow the engaging portion 41 to pass through the positioning hole 21, and the width of the tightening end 212 gradually decreases in a direction away from the receiving end 211. The receiving end 211 and the tightening end 212 are spaced apart along the second direction Y2, and the receiving end 211 is located between the tightening end 212 and the top plate 13 in the second direction Y2.

In this way, the engaging portion 41 can conveniently pass through the positioning hole 21 from the accommodating end 211 and then move along the second direction Y2, so that the engaging portion 41 is matched with the tightening end 212, and the limiting portion 42 enters the side, away from the cover plate 30, of the connecting plate 20 along the first direction Y1, so that the matching difficulty of the engaging portion 41 and the positioning hole 21 is reduced. Meanwhile, the width of the tightening end 212 gradually decreases in the direction away from the accommodating end 211, so that the tightening end 212 can play a role in tightening and clamping the clamping portion 41, and not only can play a limiting role between the cover plate 30 and the housing 10 in the second direction Y2, but also can realize stable clamping between the connecting plate 20 and the clamping portion 41. Meanwhile, the two hole surfaces of the positioning hole 21, which are oppositely arranged along the third direction Y3, can play a role of clamping the tightening end 212, and the first direction Y1, the second direction Y2 and the third direction Y3 are mutually perpendicular, so that the clamping stability of the clamping part 41 and the connecting plate 20 along the third direction Y3 is reduced, the possibility that the connecting plate 20 and the cover plate 30 shake along the third direction Y3 is reduced, and the fixing reliability of the shell 10 and the cover plate 30 is improved.

Optionally, in this embodiment, referring to fig. 5, a side of the connecting plate 20 away from the cover plate 30 is further provided with a mating protrusion 22. Through additionally setting up the cooperation protruding 22, can lengthen the size of the connecting plate 20 of constant head tank 50 centre gripping in first direction Y1, increase the area of contact between clamping portion 41 and the connecting plate 20 to improve constant head tank 50 and connecting plate 20 joint complex reliability in first direction Y1, further improve apron 30 and casing 10 along first direction Y1's installation steadiness, improve the homogeneity degree of the installation gap between apron 30 and the casing 10.

In the present embodiment, referring to fig. 7 and 8 in cooperation, in the first direction Y1, the projection of the upper surface of the engaging protrusion 22 on the connection plate 20 coincides with the projection of a part of the hole surface of the positioning hole 21 on the connection plate 20. That is, the hole surface of the tightening end 212 of the positioning hole 21 elastically abuts against the upper surface of the fitting projection 22. In this way, the engaging portion 41 can be kept in contact with the surface of the engaging protrusion 22 and the hole surface of the positioning hole 21, so that the engaging portion 41 can be engaged with the connecting plate 20 more stably and reliably, and the reliability of the joint holding the connecting plate 20 by the cover plate 30, the engaging portion 41, and the stopper 42 can be further improved.

In other embodiments, the groove surfaces of the grooves on the engaging projections 22 may be disposed obliquely in the first direction Y1 in a direction approaching the bottom plate 11 or obliquely in the first direction Y1 in a direction approaching the top plate 13.

Further, referring to fig. 8, the lower surface of the engaging portion 41 is provided with a first positioning curved surface 413, and the upper surface of the engaging protrusion 22 is provided with a second positioning curved surface 221, and the first positioning curved surface 413 is attached to the second positioning curved surface 221. In this way, the second positioning curved surface 221 can form a clamping force on the engaging portion 41, thereby improving the mounting reliability of the engaging portion 41 on the fitting projection 22.

Further, the engaging portion 41 is made of an elastic material and elastically abuts against the hole surface of the tightening end 212 and the upper surface of the fitting projection 22. In this way, not only the reliability of clamping the clamping portion 41 between the tightening end 212 and the fitting protrusion 22 can be improved, but also any position of the clamping portion 41 can be firmly fitted with the positioning hole 21 and the fitting protrusion 22, so that the position of the clamping portion 41 fitted in the positioning hole 21 in the first direction Y1 can be conveniently adjusted, the distance between the cover plate 30 connected to the clamping portion 41 and the connecting plate 20 along the first direction Y1, namely, the mounting gap between the cover plate 30 and the housing 10 can be adjusted to a proper size simply and conveniently. In addition, in the process of loading the engaging portion 41 into the positioning hole 21 or taking out the engaging portion 41 from the positioning hole 21, the engaging portion 41 of the elastic material can deform when blocked by the positioning hole 21, so that the engaging portion 41 can be smoothly loaded into the positioning hole 21 or taken out from the positioning hole 21, the possibility that the engaging portion 41 is blocked by the positioning hole 21 is greatly reduced, and the convenience in assembling and disassembling the engaging portion 41 is improved.

Further, it is possible to facilitate the engagement portion 41 to simultaneously elastically abut against the hole surface of the positioning hole 21 and the upper surface of the fitting projection 22, thereby improving the reliability of tightening the engagement portion 41 by the tightening end 212 and the fitting projection 22.

In this embodiment, referring to fig. 8 to 10, the engaging portion 41 includes an engaging section 411 and engaging sections 412 connected to two sides of the engaging section 411, and the engaging sections 412 are inclined in a direction away from the engaging section 411 toward a direction approaching the top plate 13, so that the first positioning curved surface 413 of the engaging portion 41 is U-shaped. Meanwhile, the second positioning curved surface 221 is also formed by concave upper surface of the mating protrusion 22, so that the projection of the upper surface of the mating protrusion 22 on the connecting plate 20 coincides with the projection of the tightening end 212 on the connecting plate 20.

Of course, in other embodiments, the engaging section 412 may be inclined in a direction approaching the bottom plate 11 in a direction away from the attaching section 411, and the first positioning curved surface 413 of the engaging portion 41 may be formed in an upwardly convex shape. At this time, the second positioning curved surface 221 is formed convexly from the upper surface of the fitting projection 22. In this case, the tightening end 212 is provided with a convex surface protruding toward the receiving end 211 on a side away from the receiving end 211, and the projection of the upper surface of the engaging protrusion 22 on the connection plate 20 may be overlapped with the projection of the tightening end 212 on the connection plate 20.

Further, referring to fig. 9, two engaging sections 412 are close to the surface of the top plate 13 along the second direction Y2, a slant 4121 is formed on a side of the first direction Y1 away from the cover plate 30, and the slant 4121 is obliquely disposed along the direction of the first direction Y1 away from the cover plate 30 toward the direction of the second direction Y2 approaching to the bottom plate 11, so that the engaging sections 412 can be conveniently tightened by the engaging protrusions 22, so as to further improve the reliability of elastic abutment between the engaging portion 41 and the engaging protrusions 22. In addition, the portion of the engaging section 412 provided with the inclined surface 4121 has a smaller size in the second direction Y2, so that the end of the engaging portion 41 provided with the limiting portion 42 is not easy to be limited and blocked when penetrating into the receiving end 211 of the positioning hole 21, thereby improving the assembling convenience of the engaging portion 41.

In other embodiments, the surfaces of the two engaging sections 412 near the top plate 13 along the second direction Y2 may be planar.

Meanwhile, referring to fig. 9, the positioning hole 21 is provided with a chamfer 23 at the opening 15 of the connection plate 20 on the side facing the cover plate 30, so that the engaging portion 41 is fitted into the positioning hole 21.
