It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The chassis provided by the embodiment of the present application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 15, the embodiment of the application discloses a chassis, including a case 100, a panel 200 and a connecting piece 300, where the panel 200 is detachably disposed at an opening of the case 100 to enclose an accommodating space, so as to facilitate the setting of various accessories, and the panel 200 can play a role in protection. At least part of the panel 200 is located in the box 100, the panel 200 includes a main board 210 and a side board 220 which are connected, the side board 220 is opposite to the side wall of the box 100, optionally, the main board 210 is provided with a plurality of heat dissipation holes 212, so as to dissipate heat for various accessories in the accommodating space; further alternatively, the cross-sectional shape of the heat radiation hole 212 may be circular, triangular, quadrangular, hexagonal, or the like, without being particularly limited thereto.

The first end of the connection member 300 is connected with the side plate 220, one of the second end of the connection member 300 and the inner side wall of the case 100 is provided with a positioning protrusion 311, the other is provided with a positioning groove 110, the positioning protrusion 311 can pass through the through hole 221 of the side plate 220 to be in positioning fit with the positioning groove 110 so as to connect the panel 200 with the case 100, and in case the connection member 300 is deformed, the positioning protrusion 311 is disengaged from the positioning groove 110 so as to separate the panel 200 from the case 100.

In the embodiment of the present application, when the panel 200 needs to be detached from the case 100, the user can manually drive the connector 300 to deform so that the positioning protrusion 311 is disengaged from the positioning groove 110, thereby separating the panel 200 from the case 100. Therefore, the panel 200 in the application can be assembled and disassembled without tools such as a screwdriver, and plastic parts are not needed, so that the manufacturing cost is low. Therefore, the present application can solve the problem that the present panel 200 cannot be assembled and disassembled conveniently and has low manufacturing cost.

Alternatively, the connector 300 may be made of stainless steel, which uses the elastic deformation characteristics of stainless steel material to realize the unlocking function of the connector 300.

In an alternative implementation, the connecting piece 300 includes a connecting portion 310, alternatively, the connecting portion 310 may be in a plate structure, a first end of the connecting portion 310 is connected to the side plate 220, a second end of the connecting portion 310 has a positioning protrusion 311, an inner side wall of the case 100 is provided with a positioning groove 110, and of course, a second end of the connecting portion 310 may also be provided with a positioning groove 110, and an inner side wall of the case 100 has a positioning protrusion 311. At this time, the connection portion 310 is exposed, which not only causes other structures to easily contact with the connection member 300 and deform, thereby causing the panel 200 to be erroneously detached, but also may affect the aesthetic appearance of the entire cabinet. Therefore, the main board 210 is provided with the avoidance opening 211, so that the connecting piece 300 is located in the accommodating cavity enclosed by the box body 100 and the panel 200, and at this time, the user can pass through the avoidance opening 211 to manually drive the connecting portion 310 to deform, so as to avoid contact with other structures, and meanwhile, the aesthetic property of the case can be improved, but the avoidance opening 211 needs to be close to the side board 220, so that the manual driving of the connecting portion 310 deforms, and therefore, the setting position of the avoidance opening 211 is limited. Based on this, optionally, the connector 300 further includes an unlocking portion 320, where the unlocking portion 320 is disposed opposite to the main board 210, and the unlocking portion 320 is bent with respect to the connecting portion 310, where bending of the unlocking portion 320 with respect to the connecting portion 310 specifically means that an included angle between the unlocking portion 320 and the connecting portion 310 may be approximately equal to 90 °; alternatively, when the panel 200 is mounted on the case 100, the unlocking portion 320 may be attached to the main board 210, so as to facilitate the setting of the connector 300. Part of the unlocking part 320 is exposed out of the avoiding opening 211, and the unlocking part 320 can drive the connecting part 310 to deform, so that the positioning protrusion 311 is disengaged from the positioning groove 110. In the scheme, the finger of the user can extend into the avoidance opening 211 to drive the unlocking part 320 to drive the connecting part 310 to deform, and the setting position of the avoidance opening 211 is flexible; meanwhile, part of the unlocking part 320 is exposed out of the avoidance opening 211, so that a user can contact the unlocking part 320 and apply a force to the unlocking part 320.

Alternatively, the connection part 310 may have a flat plate-like structure; alternatively, in other alternative embodiments, the connecting portion 310 includes a first plate segment 312 and a second plate segment 313 that are connected, where an end of the first plate segment 312 away from the second plate segment 313 is connected to the side plate 220, an end of the second plate segment 313 away from the first plate segment 312 is provided with a positioning protrusion 311, the unlocking portion 320 is connected to the second plate segment 313, and a first included angle is formed between the first plate segment 312 and the second plate segment 313, where the first included angle becomes smaller when the connecting portion 310 is deformed. When the unlocking part 320 is manually driven to move along the direction away from the inner side wall of the box 100, the unlocking part 320 drives the second plate section 313 to move together, at this time, the connecting part 310 deforms, and the first included angle becomes smaller. The connection part 310 is arranged into two connected parts, so that a user can apply a small driving force to drive the second plate section 313 to rotate relative to the first plate section 312, and the positioning protrusion 311 is disengaged from the positioning groove 110. Of course, when the positioning protrusion 311 is matched with the positioning groove 110, the first plate segment 312 and the second plate segment 313 may be located on the same plane, and when the unlocking portion 320 is manually driven, the unlocking portion 320 drives the second plate segment 313 to rotate relative to the first plate segment 312, so as to form an included angle.

Alternatively, the first included angle may be 170 ° to 178 °, where the space occupied by the connecting portion 310 in the width direction of the main board 210 is smaller, and accordingly, the height of the positioning protrusion 311 may be set smaller, and in the process of positioning engagement or disengagement of the positioning protrusion 311 and the positioning groove 110, the movement path of the positioning protrusion 311 may be smaller. Further alternatively, the first included angle may be 175 °, in which case it is not only convenient to drive the second plate section 313 to rotate relative to the first plate section 312, but also the movement path of the positioning protrusion 311 may be narrowed. Of course, the first included angle may be flexibly selected according to actual needs, which is not specifically limited in the embodiment of the present application.

Alternatively, the surface of the connecting portion 310 facing the side plate 220 may be provided with a positioning protrusion 311, and the positioning protrusion 311 may have a plate-shaped structure, in which the cross-sectional area of the plate-shaped structure is gradually reduced in a direction perpendicular to the side plate 220, that is, the plate-shaped structure has a triangular structure, and the positioning protrusion 311 of such a structure has a guiding function in the process that the positioning protrusion 311 passes through the through hole 221 of the side plate 220 to be in positioning engagement with the positioning groove 110.

Optionally, a connecting protrusion 314 may be further disposed on a surface of the connecting portion 310 facing the side plate 220, and the connecting protrusion 314 is riveted with the side plate 220, which has the characteristics of simple operation, high connection strength and good tightness.

Further alternatively, the number of the coupling protrusions 314 may be at least two, and the coupling protrusions 314 may be spaced apart along the length direction of the coupling portion 310, thereby improving the firmness of the coupling 300.

In an alternative embodiment, the unlocking portion 320 is provided with an operation hole 321, a pressing surface 321a is disposed at the lowest position of the operation hole 321, and the pressing surface 321a is located at a position higher than the position at the lowest position of the avoidance opening 211. When the panel 200 needs to be detached from the case 100, the user can manually press the pressing surface 321a to deform the connecting portion 310, and the positioning protrusion 311 is disengaged from the positioning groove 110, so that the unlocking manner is simpler and the operability is stronger. Of course, the user may pull down the highest portion of the operation hole 321 to deform the connection portion 310.

It should be noted that, the distance between the pressing surface 321a and the lowest position of the avoidance opening 211 is greater than the height of the positioning protrusion 311, so as to ensure that when the pressing surface 321a presses to the lowest position of the avoidance opening 211, the positioning protrusion 311 is disengaged from the positioning groove 110, and the positioning protrusion 311 extends out of the positioning groove 110.

In a further alternative embodiment, in the direction perpendicular to the side plate 220, a first distance A2 is provided between the pressing surface 321a and the lowest position of the avoiding opening 211, and the ratio between the first distance A2 and the height A1 of the positioning protrusion 311 is 1.05-1.15. When the user manually presses the pressing surface 321a of the operation hole 321, the connection portion 310 deforms, the positioning protrusion 311 is disengaged from the positioning groove 110, if the pressing surface 321a is continuously pressed, the connection portion 310 is continuously deformed, and the connection portion 310 is easily damaged, so that the ratio between the first distance A2 and the height A1 of the positioning protrusion 311 is set to be 1.05-1.15, that is, the first distance A2 is greater than 5-15% of the height A1 of the positioning protrusion 311, the lowest part of the avoidance opening 211 can limit the pressing finger, and the connection portion 310 is protected; further alternatively, when the connecting member 300 is made of stainless steel, the deformation of the stainless steel material exceeds the yield strength, and therefore, the ratio between the first distance A2 and the height A1 of the positioning protrusion 311 cannot be excessively large, the ratio can be set to 1.1, and the fingers are limited as early as possible in the pressing process, so that the connecting portion 310 is prevented from being damaged and failing. Of course, the ratio between the first distance A2 and the height A1 of the positioning protrusion 311 may be flexibly selected according to actual needs, which is not particularly limited in the embodiment of the present application.

Optionally, the avoidance opening 211 may be rectangular, but when the user manually presses the pressing surface 321a of the operation hole 321, the finger abdomen of the finger is an arc surface, so the operation hole 321 is generally set to be a circular structure, when the finger contacts the lowest position of the avoidance opening 211, the contact area between the finger abdomen and the avoidance opening 211 is smaller, the comfort of the user is poor, and even the finger is scratched, so the lowest position of the avoidance opening 211 may be set to be an arc surface, so that the contact area between the avoidance opening 211 and the finger abdomen is increased.

Alternatively, the avoiding opening 211 may be a circular hole, and in this case, in a direction perpendicular to the side plate 220, in order to ensure that the finger has enough movement space, the avoiding opening 211 needs to be set larger, and various accessories in the accommodating space are easy to be exposed; therefore, the cross section of the avoidance opening 211 is an oval structure, and the long axis of the oval structure extends along the direction perpendicular to the side plate 220, so that not only can enough movement space be ensured when the finger is pressed, but also various accessories in the accommodating space can be prevented from being exposed, so that impurities such as dust can be reduced to enter the accommodating space, and meanwhile, the attractiveness of the chassis can be improved.

In another alternative embodiment, an annular protrusion 322 is disposed on a side of the unlocking portion 320 facing away from the main board 210, the annular protrusion 322 is disposed around the operation hole 321, and an inner annular surface of the annular protrusion 322 extends to a side wall of the operation hole 321, so that an area of the pressing surface 321a is increased, a finger of a user is prevented from being scratched by the side wall of the operation hole 321 in the process of pressing and unlocking, and further user experience is improved. Of course, the annular protrusion 322 may also be disposed on the surface of the unlocking portion 320 facing the main board 210, at this time, the annular protrusion 322 may be at least partially located in the avoidance opening 211, when the annular protrusion 322 moves to contact with the lowest part of the avoidance opening 211, the annular protrusion 322 may be limited, at this time, the finger may not need to contact the side wall of the avoidance opening 211, which is beneficial to improving the safety of the panel 200 during the installation process.

Alternatively, the number of the connection members 300 may be one; alternatively, in other alternative embodiments, the number of the connectors 300 is at least two, including the first connectors 330 and the second connectors 340 that are disposed at intervals, the first connectors 330 and the second connectors 340 are disposed opposite to each other along the width direction of the motherboard 210, and the unlocking direction of the unlocking portion 320 of the first connector 330 is opposite to the unlocking direction of the unlocking portion 320 of the second connector 340, and the through holes 221 and the positioning grooves 110 are disposed in one-to-one correspondence with the connectors 300. In this scheme, by providing at least two connectors 300, the installation stability of the panel 200 is facilitated; further, the unlocking direction of the unlocking portion 320 of the first connector 330 is opposite to the unlocking direction of the unlocking portion 320 of the second connector 340, and at this time, the user can drive the different unlocking portions 320 by two fingers of one hand respectively to unlock the first connector 330 and the second connector 340. Of course, the first connector 330 and the second connector 340 may be disposed at intervals along the length direction of the main board 210, and at this time, the unlocking direction of the unlocking portion 320 of the first connector 330 is the same as the unlocking direction of the unlocking portion 320 of the second connector 340.

In a further alternative embodiment, the at least two connectors 300 may further include a third connector 350 and a fourth connector 360 disposed at intervals, where the third connector 350 and the fourth connector 360 are disposed opposite to each other along the width direction of the main board 210, and the unlocking direction of the unlocking portion 320 of the third connector 350 is opposite to the unlocking direction of the unlocking portion 320 of the fourth connector 360, and in the length direction of the main board 210, the first connector 330 and the second connector 340 are located at one end of the main board 210, and the third connector 350 and the fourth connector 360 are located at the other end of the main board 210, i.e. the panel 200 is in a structure with symmetry between the top and bottom and the left and right, so that the installation direction may not be considered, which is beneficial to improving the installation efficiency at the panel 200.

In yet another alternative embodiment, the side plate 220 is provided with a clamping groove 222, alternatively, the clamping groove 222 may be an elongated structure, and the length direction of the elongated structure is the same as the circumferential direction of the side plate 220. The clamping groove 222 is close to the connection position between the side plate 220 and the main plate 210, the chassis further comprises a positioning piece 400, one end of the positioning piece 400 is clamped in the clamping groove 222, the other end of the positioning piece 400 is clamped in the edge of the side plate 220, the positioning piece 400 is provided with a protruding portion 410, and the protruding portion 410 can be abutted against the inner side wall of the case 100, so that the panel 200 is matched with the case 100 in a positioning manner through the positioning piece 400. Since there is an assembly gap between the panel 200 and the inner sidewall of the case 100 when the panel 200 is mounted to the case 100, the panel 200 is positioned by the positioning member 400 at this time, thereby improving the mounting stability of the panel 200.

Alternatively, the protruding portion 410 may be in an inelastic deformation structure, where the assembly gap between the panel 200 and the inner sidewall of the case 100 and the height of the protruding portion 410 need to be precisely calculated, which is difficult to design; based on this, the protruding portion 410 is optionally in a deformable structure, and at this time, the protruding portion 410 may be deformed to adapt to the assembly gaps with different sizes, so as to reduce the design difficulty of the positioning member 400.

Further alternatively, the positioning member 400 includes a first positioning portion 420, a protruding portion 410, and a second positioning portion 430, where the first positioning portion 420 and the second positioning portion 430 are sequentially connected, each of the protruding portion 410 is bent, the first positioning portion 420 and the second positioning portion 430 are disposed opposite to each other, the first positioning portion 420 is clamped in the clamping slot 222, the thickness of the first positioning portion 420 is smaller than the width of the clamping slot 222, and the second positioning portion 430 is clamped at the edge of the side plate 220. When the protruding portion 410 deforms, the distance between the first positioning portion 420 and the second positioning portion 430 increases, and at this time, the width of the clamping groove 222 is greater than the thickness of the first positioning portion 420, so as to provide a movement space for the first positioning portion 420.

Alternatively, the second positioning portion 430 may be fixed to an edge of the side plate 220, and only the first positioning portion 420 moves along the width direction of the clamping groove 222, where the first positioning portion 420 may be a slider, and when the protruding portion 410 deforms, the first positioning portion 420 slides along the clamping groove 222; alternatively, in other embodiments, the first positioning portion 420 and the second positioning portion 430 each include an arc-shaped plate segment 421 and a flat plate segment 422, the arc-shaped plate segment 421 is connected between the flat plate segment 422 and the protruding portion 410, the flat plate segment 422 and the protruding portion 410 are oppositely arranged, and the flat plate segment 422 and the side plate 220 are attached to one surface facing away from the protruding portion 410, so that the contact area between the positioning member 400 and the side plate 220 is increased, and the stability of the positioning member 400 is further improved; also, both the first and second positioning portions 420 and 430 are slidable with respect to the side plate 220, thereby preventing the positioning member 400 from being inclined.

Alternatively, the boss 410 may be an arc-shaped structure; alternatively, in another embodiment, the protruding portion 410 includes a first inclined plate section 411, an arc-shaped connecting plate section 412 and a second inclined plate section 413 connected in sequence, where the first inclined plate section 411 is connected to the first positioning portion 420, the second inclined plate section 413 is connected to the second positioning portion 430, and a second included angle is formed between the first inclined plate section 411 and the second inclined plate section 413, and the arc-shaped connecting plate section 412 may abut against an inner sidewall of the case 100, so that the second included angle becomes larger. In this embodiment, the protruding portion 410 has a V-shaped structure, which has a lower center of gravity and better structural stability, and when the arc-shaped connecting plate segment 412 receives a larger force, the range of variation of the second included angle is larger, and accordingly, the positioning member 400 with this structure can be suitable for assembly gaps with more sizes, and has a wider application range; in addition, the arc-shaped connecting plate section 412 can be abutted against the inner side wall of the box body 100, the contact area between the arc-shaped connecting plate section and the inner side wall of the box body 100 is large, and stress concentration can be avoided, so that the inner side wall of the box body 100 is protected.

Alternatively, the number of the clamping grooves 222 may be one; or, the number of the clamping grooves 222 is at least two, and each clamping groove 222 is arranged along the circumferential direction of the side plate 220 at intervals, and the positioning pieces 400 are arranged in one-to-one correspondence with the clamping grooves 222, so that the installation stability of the panel 200 is further improved.

In still another alternative embodiment, the side plate 220 has a guiding portion 223 on a side facing away from the main plate 210, alternatively, the guiding portion 223 may be a plate structure, specifically may be a folded edge design, the guiding portion 223 may be disposed obliquely with respect to the side plate 220, and when the panel 200 is mounted on the case 100, the guiding portion 223 of the panel 200 is inserted into the opening of the case 100, so as to provide guidance for the side plate 220, so as to avoid the side plate 220 from being jammed, thereby improving the mounting efficiency of the panel 200. Alternatively, in the circumferential direction of the side plate 220, the guide portion 223 is offset from the locking groove 222, so as to facilitate the positioning of the positioning member 400.

Alternatively, in the embodiment where the protruding portion 410 is in a deformable structure, the guiding portion 223 is offset from the engaging groove 222 in the circumferential direction of the side plate 220, so as to provide a movement space for the second positioning portion 430.

Alternatively, the number of the guide parts 223 is at least two, and each guide part 223 is disposed at intervals along the circumferential direction of the side plate 220, thereby further improving the guiding accuracy thereof and further improving the installation efficiency of the panel 200.
