[0046] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used merely for the purpose of explaining the present application, and should not be construed as limiting the present application.

[0047] The following detailed description of the application refers to the accompanying drawings listed below: Figures 1-11 A chassis assembly 10 according to an embodiment of the present application is described below.

[0048] Referring to Figure 4 , Figure 5 and Figure 7 , the chassis assembly 10 according to the first embodiment of the present application comprises a base 11, a housing assembly 12, and a decorative cover 14. The base 11 comprises a first connecting portion 112, the bottom of the housing assembly 12 is provided with a second connecting portion 121, the second connecting portion 121 is located outside the first connecting portion 112 and is connected to the first connecting portion 112, and the decorative cover 14 is detachably mounted outside the second connecting portion 121. Wherein, the outside of the first connecting portion 112 and the second connecting portion 121 refers to the side of the first connecting portion 112 and the second connecting portion 121 facing the outside of the chassis assembly 10. By locating the second connecting portion 121 outside the first connecting portion 112, it is convenient to perform the connecting operation on the first connecting portion 112 and the second connecting portion 121 outside the first connecting portion 112, for example, the first connecting portion 112 and the second connecting portion 121 can be connected together by passing a fastener (such as a screw). Since the space outside the second connecting portion 121 is larger, the connecting operation between the first connecting portion 112 and the second connecting portion 121 can be more convenient by performing the dismounting operation on the decorative cover 14 outside the second connecting portion 121, effectively reducing the operation difficulty.

[0049] The decorative cover 14 is detachably mounted outside the second connecting portion 121, so that the decorative cover 14 can cover the connecting point between the first connecting portion 112 and the second connecting portion 121. When it is necessary to remove the connecting relationship between the first connecting portion 112 and the second connecting portion 121, the decorative cover 14 is dismounted from the second connecting portion 121 outside the second connecting portion 121, so that the connecting point between the second connecting portion 121 and the first connecting portion 112 is exposed outside the housing assembly 12, thereby facilitating the operation on the connecting point between the first connecting portion 112 and the second connecting portion 121 outside the second connecting portion 121, without the need to dismount at least part of the housing assembly 12 to operate the connecting point of the first connecting portion 112 and the second connecting portion 121.

[0050] And, since the space outside the second connecting portion 121 is larger, by performing the dismounting operation of the decorative cover 14 outside the second connecting portion 121, the dismounting operation of the decorative cover 14 can be made more convenient, and by performing the operation on the connecting point between the second connecting portion 121 and the first connecting portion 112 outside the shell assembly 12, the operation difficulty can be effectively reduced, the assembly or disassembly operation between the first connecting portion 112 and the second connecting portion 121 is more convenient, thereby facilitating the replacement or maintenance of the shell assembly 12 or the base 11, and the disassembly efficiency between the shell assembly 12 and the base 11 is improved.

[0051] Optionally, there are multiple connecting points between the first connecting portion 112 and the second connecting portion 121, and a single decorative cover 14 can extend along the circumference of the second connecting portion 121, when the connecting points are multiple and the multiple connecting points are arranged at intervals along the circumference of the second connecting portion 121, a single decorative cover 14 can also cover multiple connecting points at the same time, and it is not necessary to separately arrange a corresponding decorative cover 14 at each connecting point, and the decorative cover 14 only needs to be installed once, which can further improve the disassembly efficiency between the shell assembly 12 and the base 11.

[0052] According to the shell assembly 10 of the embodiment of the utility model, the decorative cover 14 is installed outside the second connecting portion 121, so that the decorative cover 14 covers the connecting point between the second connecting portion 121 and the first connecting portion 112, and the decorative cover 14 can be dismounted from the second connecting portion 121 outside the second connecting portion 121, so that the connecting point between the second connecting portion 121 and the first connecting portion 112 is exposed outside the shell assembly 12, which makes the dismounting or installation of the decorative cover 14 more convenient, the connecting point between the first connecting portion 112 and the second connecting portion 121 can be directly connected or dismounted outside the shell assembly 12, and the operation outside the shell assembly 12 can make the operation space larger, thereby facilitating the replacement or maintenance of the shell assembly 12 or the base 11, effectively reducing the operation difficulty, and improving the disassembly efficiency between the shell assembly 12 and the base 11.

[0053] Referring to Figures 6-9 According to some embodiments of the utility model, the decorative cover 14 and the second connecting portion 121 are connected in a clamping manner, which makes the connection between the decorative cover 14 and the second connecting portion 121 simple and has strong stability, and facilitates the replacement or maintenance of the decorative cover 14.

[0054] Referring to Figures 6-9According to some embodiments of the utility model, the second connecting part 121 is formed with a clamping groove 123, the decorative cover 14 is provided with an elastic buckle 141, and the elastic buckle 141 is clamped into the clamping groove 123. Through the elastic buckle 141 on the decorative cover 14 being clamped into the clamping groove 123 of the second connecting part 121, the clamping connection between the elastic buckle 141 and the clamping groove 123 enables the decorative cover 14 to be detachably installed on the second connecting part 121, and the clamping connection between the elastic buckle and the clamping groove 123 is simple, so that the decorative cover 14 is easy to disassemble and assemble.

[0055] For example, the assembly process between the decorative cover 14 and the second connecting part 121 can be that the elastic buckle 141 can be more smoothly clamped into the clamping groove 123 through the elastic deformation of the elastic buckle 141 itself, and when the elastic buckle 141 is clamped into the clamping groove 123, the elastic buckle 141 restores to the original state under the elastic restoring force of itself, so that the elastic buckle 141 is more stably clamped in the clamping groove 123, and the possibility of relative movement between the decorative cover 14 and the second connecting part 121 is reduced or avoided.

[0056] Referring to Figures 6-9 According to some embodiments of the utility model, the clamping groove 123 is a plurality of clamping grooves, the plurality of clamping grooves 123 are arranged at intervals along the circumference of the shell assembly 12, the number of the elastic buckles 141 is the same as the number of the clamping grooves 123, and the elastic buckles 141 and the clamping grooves 123 correspond to each other one by one, which can further enhance the connection stability between the decorative cover 14 and the second connecting part 121 and effectively reduce the possibility of relative movement between the decorative cover 14 and the second connecting part 121 caused by external impact or vibration.

[0057] In the description of the utility model, the meaning of "a plurality of" is two or more than two.

[0058] Referring to Figures 6-9 According to some embodiments of the utility model, the elastic buckle 141 comprises two opposite and spaced sub-elastic buckles 142, and when the elastic buckle 141 is clamped into the clamping groove 123, the two sub-elastic buckles 142 can form a clamping connection with the clamping groove 123 respectively, so that the stability of the connection between the elastic buckle 141 and the clamping groove 123 can be improved.

[0059] Each sub-elastic buckle 142 comprises an elastic rib plate 143 and a buckle protrusion 144 arranged on the elastic rib plate 143, the elastic rib plate 143 can provide a supporting action on the buckle protrusion 144, and in the process of clamping the two sub-elastic buckles 142 into the clamping groove 123, the elastic rib plate 143 can be elastically deformed, so that the sub-elastic buckle 142 can be smoothly clamped into the clamping groove 123 or separated from the clamping groove 123, and the mutual interference between the sub-elastic buckle 142 and the clamping groove 123 is avoided to prevent the sub-elastic buckle 142 from being clamped.

[0060] The buckle protrusions 144 on the two elastic rib plates 143 are respectively connected to the sides of the two elastic rib plates 143 away from each other, the elastic rib plates 143 are inserted into the clamping groove 123, the buckle protrusions 144 are located on the side of the second connecting portion 121 away from the decorative cover 14, and the buckle protrusions 144 abut against the second connecting portion 121. The abutting relationship between the buckle protrusions 144 and the second connecting portion 121 can limit the buckle protrusions 144, thereby forming a limiting relationship between the elastic buckle 141 and the clamping groove 123, avoiding the elastic buckle 141 from being randomly taken out of the clamping groove 123, and improving the stability of the clamping relationship between the elastic buckle 141 and the clamping groove 123, thereby enhancing the stability of the connecting relationship between the decorative cover 14 and the second connecting portion 121.

[0061] With reference to Figure 7 and Figure 9 According to some embodiments of the present application, two guide inclined surfaces 145 are formed on the buckle protrusions 144, in the clamping direction of the elastic buckle 141, the two guide inclined surfaces 145 are located on the opposite sides of the buckle protrusions 144, and in the protruding direction of the buckle protrusions 144 relative to the elastic rib plates 143, the two guide inclined surfaces 145 of the buckle protrusions 144 extend in a direction of approaching each other. By extending in a direction of approaching each other, the two guide inclined surfaces 145 of the buckle protrusions 144 can guide the assembly of the elastic rib plates 143 and the clamping groove 123, and the assembly of the elastic rib plates 143 and the clamping groove 123 can be completed with relatively small force, facilitating the disassembly or assembly of the elastic rib plates 143 and the clamping groove 123.

[0062] With reference to Figure 6 and Figure 7 According to some embodiments of the present application, an elastic opening 146 is formed on the elastic rib plate 143, and the elastic opening 146 extends along the circumference of the buckle protrusion 144. When the elastic rib plate 143 is clamped into or separated from the clamping groove 123, the elastic opening 146 can deform the buckle protrusion 144 with relatively small force, so that the assembly or disassembly of the elastic rib plate 143 and the clamping groove 123 can be achieved with relatively small force, and the assembly or disassembly of the elastic buckle 141 and the second connecting portion 121 can be facilitated.

[0063] With reference to Figure 8 and Figure 9According to some embodiments of the utility model, the gap range between the elastic buckle 141 and the inner wall of the clamping groove 123 is 0.05mm~0.3mm. For example, the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 can be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc. By making the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 not less than 0.05mm, a certain assembly error can be allowed to exist between the elastic buckle 141 and the inner wall of the clamping groove 123, so that the assembly or disassembly between the elastic buckle 141 and the clamping groove 123 is smoother. By making the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 not more than 0.3mm, it can be ensured that the decorative cover 14 can effectively shield the connection point of the second connecting part 121 and the first connecting part 112, improve the overall aesthetics of the shell assembly 10, and avoid that the gap between the decorative cover 14 and the shell assembly 12 is too large due to the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 being too large.

[0064] For example, if the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 is greater than 0.3mm, since the second connecting part 121 is located at the bottom of the shell assembly 12, the decorative cover 14 will move downward relative to the second connecting part 121 under the action of its own gravity, causing the gap between the upper edge of the decorative cover 14 and the shell assembly 12 to be too large, thereby affecting the overall aesthetics. By making the gap between the elastic buckle 141 and the inner wall of the clamping groove 123 not more than 0.3mm, the gap between the upper end of the decorative cover 14 and the shell assembly 12 can be kept within a small range after the decorative cover 14 moves downward under its own gravity, so that the decorative cover 14 can effectively shield the connection point of the second connecting part 121 and the first connecting part 112.

[0065] By making the gap range between the elastic buckle 141 and the inner wall of the clamping groove 123 be 0.05mm~0.3mm, a certain assembly error can be allowed to exist between the elastic buckle 141 and the inner wall of the clamping groove 123, so that the assembly or disassembly between the elastic buckle 141 and the clamping groove 123 is smoother, and it can also be ensured that the decorative cover 14 can effectively shield the connection point of the second connecting part 121 and the first connecting part 112, improving the overall aesthetics of the shell assembly 10.

[0066] Referring to Figures 5-7 According to some embodiments of the utility model, the first connecting part 112 is formed with an avoiding groove 113 for avoiding the elastic buckle 141. The elastic buckle 141 can be accommodated in the avoiding groove 113, which can make the structure of the decorative cover 14, the first connecting part 112 and the second connecting part 121 compact while facilitating the decorative cover 14 to cover the connection point between the first connecting part 112 and the second connecting part 121.

[0067] Referring to Figure 5 and Figure 10 According to some embodiments of the present application, the second connecting part 121 comprises a fixing lug 124 and a clamping seat 125, the fixing lug 124 and the clamping seat 125 are arranged along the circumference of the shell assembly 12, the first fixing hole 122 is formed on the fixing lug 124, the second fixing hole is formed on the first connecting part 112, the fastener is arranged in the first fixing hole 122 and the second fixing hole, and the clamping slot 123 is arranged on the clamping seat 125. The first fixing hole 122 is formed on the fixing lug 124, which can facilitate the fastener to be arranged therein, and the connection between the second connecting part 121 and the first connecting part 112 can be realized by arranging the fastener in the first fixing hole 122 and the second fixing hole. The clamping slot 123 on the clamping seat 125 can limit the elastic buckle 141, and ensure that the assembly position between the decorative cover 14 and the second connecting part 121 is accurate, so that the decorative cover 14 effectively shields the connecting point on the fixing lug 124 adjacent to the clamping seat 125.

[0068] Referring to Figure 10 According to some embodiments of the present application, the outer surface of the clamping seat 125 is outwardly protruded relative to the outer surface of the fixing lug 124, which can effectively avoid the interference between the decorative cover 14 and the fixing lug 124 or the fastener. For example, if the outer surface of the clamping seat 125 is flush with the outer surface of the fixing lug 124 or the clamping seat 125 is located on the inner side of the fixing lug 124, the decorative cover 14 is easy to interfere with the fixing lug 124 or the fastener. By outwardly protruding the outer surface of the clamping seat 125 relative to the outer surface of the fixing lug 124, the decorative cover 14 can effectively shield the first fixing hole 122 on the fixing lug 124 or the fastener, and the interference between the decorative cover 14 and the fixing lug 124 or the fastener can also be effectively avoided.

[0069] Referring to Figures 5-7 According to some embodiments of the present application, the lower end of the shell assembly 12 is provided with a mounting gap 126, the second connecting part 121 is opposite to the mounting gap 126, and the second connecting part 121 and the shell assembly 12 jointly define a containing groove 127, the mounting gap 126 constitutes an open mouth of the containing groove 127, and at least part of the decorative cover 14 is contained in the containing groove 127. Wherein, the at least part of the decorative cover 14 contained in the containing groove 127 can include the following cases: for example, part of the decorative cover 14 is located in the containing groove 127; for another example, all of the decorative cover 14 is located in the containing groove 127.

[0070] The installation gap 126 can facilitate the operator to disassemble and assemble the first connecting part 112 and the second connecting part 121 from the outside of the second connecting part 121.
