The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0048] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 A schematic diagram of a partial structure of a base provided in an embodiment of the present application; Figure 2 A schematic diagram of a partial structure of a connection structure provided in an embodiment of the present application; Figure 3 A cross-sectional view of a base fixing structure provided in one embodiment of the present application;

[0049] Figure 4A schematic diagram of the structure of a base and a shell provided in an embodiment of the present application after installation from a perspective. The embodiment of the present application provides a base fixing structure 100. The base fixing structure 100 includes a shell 10 and a base 20. Among them, the bottom of the shell 10 has a groove A. A connecting structure 11 is arranged in the groove A. The connecting structure 11 includes a first annular convex groove 111, a first boss 112 and a mounting hole 113. The base 20 includes a second boss 21 adapted to the first annular convex groove 111, a second annular convex groove 22 adapted to the first boss 112, and a mounting claw 23 adapted to the mounting hole 113; wherein the first boss 112 is inserted in the second annular convex groove 22, the second boss 21 is inserted in the first annular convex groove 111, and the mounting claw 23 is installed in the mounting hole 113. It is understandable that the annular convex groove refers to a convex portion protruding from the top surface 251 of the base 25, and a groove is provided on the side of the convex portion away from the top surface 251 of the base 25. The base fixing structure 100 provided in the present application is provided with a connection structure 11 including a first annular convex groove 111, a first convex column 112 and a mounting hole 113 on the shell 10, and then a second convex column 21 adapted to the first annular convex groove 111, a second annular convex groove 22 adapted to the first convex column 112 and a mounting claw 23 adapted to the mounting hole 113 are provided on the base 20 to achieve a stable installation and connection effect between the shell 10 and the base 20, so as to withstand the swing when subjected to unbalanced external forces in front and back and left and right, reduce the possibility of tilting and tipping due to unstable center of gravity, and further improve the installation efficiency between the base 20 and the shell 10. Compared with the existing base fixing structure 100 directly connected by screws, the effect of quick installation can be achieved without the use of tools and screws.

[0050] Among them, the side surface of the first protruding column 112 is provided with a first reinforcing rib 1121, and the top of the groove wall of the second annular protruding groove 22 is provided with a first recessed portion 22a adapted to the first reinforcing rib 1121; and / or the side surface of the second protruding column 21 is provided with a second reinforcing rib 211, and the top of the groove wall of the first annular protruding groove 111 is provided with a second recessed portion 111a adapted to the second reinforcing rib 211. Such a configuration can better fix the base 20 and the housing 10. In addition, the first reinforcing rib 1121 can make the first protruding column 112 withstand greater external force, further ensuring the strength and external force resistance of the base fixing structure 100, and the second reinforcing rib 211 can make the second protruding column 21 withstand greater external force, which also further ensures the strength and external force resistance of the base fixing structure 100. In one embodiment, the specific arrangement method may be that only the first reinforcing rib 1121 is provided on the side surface of the first boss 112, and the first recessed portion 22a matched with the first reinforcing rib 1121 is provided on the top of the groove wall of the second annular convex groove 22; or only the second reinforcing rib 211 is provided on the side surface of the second boss 21, and the second recessed portion 111a matched with the second reinforcing rib 211 is provided on the top of the groove wall of the first annular convex groove 111; or both the first reinforcing rib 1121 is provided on the side surface of the first boss 112, the first recessed portion 22a matched with the first reinforcing rib 1121 is provided on the top of the groove wall of the second annular convex groove 22, and the second reinforcing rib 211 is provided on the side surface of the second boss 21, and the second recessed portion 111a matched with the second reinforcing rib 211 is provided on the top of the groove wall of the first annular convex groove 111.

[0051] Continue to see Figures 1 to 4 , the connection structure 11 also includes a positioning column 114 and a mounting shell 116. The positioning column 114 is arranged between the first annular convex groove 111 and the first convex column 112. The positioning column 114 and the first annular convex groove 111 as well as the positioning column 114 and the first convex column 112 are connected by a third reinforcing rib 115. The third reinforcing rib 115 can improve the stability between the positioning column 114, the first annular convex groove 111 and the first convex column 112, and at the same time enable the positioning column 114 to withstand greater external force, thereby ensuring the strength of the base fixing structure 100. The base 20 also has a positioning hole 24 adapted to the positioning column 114, and the positioning hole 24 and the positioning column 114 are used to fix the housing 10 to the base 20 by screws. Such a setting provides a fixing solution of a spare screw, so as to solve the problem that if the mounting claw 23 cannot be used when the base 20 is not used normally, the base 20 can still be fixed to the housing 10 by screws.

[0052] The mounting shell 116 is disposed in the groove A. The mounting shell 116 includes an annular side wall 1161 and a top wall 1162. The annular side wall 1161 of the mounting shell 116 is spaced apart from the side wall of the groove A and is fixedly connected by a fourth reinforcing rib 117, and the annular side wall 1161 of the mounting shell 116 surrounds the first annular convex groove 111, the first convex column 112 and the positioning column 114. The fourth reinforcing rib 117 can reduce the possibility of deformation of the shape of the annular side wall 1161 of the mounting shell 116, and can also ensure the strength and external force resistance of the base fixing structure 100. Among them, after the base 20 and the shell 10 are installed, the end of the annular side wall 1161 of the mounting shell 116 away from the top wall 1162 abuts against the top surface 251 of the seat body 25.

[0053] The top wall 1162 of the mounting shell 116 is spaced from the bottom wall A1 of the groove A to form a gap, and the top wall 1162 of the mounting shell 116 has a mounting hole 113. Among them, a mounting boss 231 adapted to the mounting hole 113 is provided on the side of the mounting claw 23. The mounting boss 231 is a three-dimensional structure with inclined outer sides, wherein the thickness of the mounting boss 231 gradually decreases along the direction of the base 20 approaching the connecting structure 11. The mounting boss 231 is arranged in this way so that the mounting claw 23 can be inserted into the mounting hole 113 more smoothly and quickly, and the mounting claw 23 can enter the mounting hole 113 with minimal resistance as much as possible, so that the user only needs to use force in the last section of the assembly process during installation, which is labor-saving and more convenient to install. The annular side wall 1161 forms an arc-shaped depression H outwardly corresponding to the position of the mounting hole 113, which is used to facilitate the disassembly of the mounting claw 23. During actual use, when the user needs to disassemble the base 20, the user can insert a small screwdriver or a cylindrical rod into the mounting hole 113 from the arc-shaped recess H, and move the small screwdriver or the cylindrical rod to support the mounting boss 231 of the mounting claw 23, so that the mounting claw 23 is disengaged from the mounting shell 116, thereby completing the disassembly of the base 20.

[0054] The mounting claw 23 passes through the mounting hole 113, and the mounting boss 231 is engaged in the gap, completing the mounting engagement between the base 20 and the housing 10. The base 20 includes a base body 25. The second boss 21 and the second annular convex groove 22 are provided on the top surface 251 of the base body 25. The positioning hole 24 passes through the base body 25, and a port is located on the top surface 251 of the base body 25, which is used to allow the mounting claw 23 to pass through the mounting hole 113 and the housing 10 for mounting engagement, thereby achieving a firm assembly effect.

[0055] The first annular groove 111 is connected to the annular side wall 1161 of the mounting shell 116 by the fifth reinforcing rib 118, so that the first annular groove 111 and the annular side wall 1161 of the mounting shell 116 can withstand greater external force. The first boss 112 is connected to the annular side wall 1161 of the mounting shell 116 by the first reinforcing rib 1121, so that the first boss 112 and the mounting shell 116 can withstand greater external force, thereby ensuring the strength of the base fixing structure 100. The first reinforcing rib 1121, the third reinforcing rib 115 and the fifth reinforcing rib 118 are arranged in a colinear manner along the first direction. The first annular groove 111, the first boss 112 and the positioning column 114 all pass through the top wall 1162 of the mounting shell 116 and are connected to the bottom wall A1 of the groove A. By connecting the top wall 1162 of the mounting shell 116 with the bottom wall A1 of the groove A, this arrangement is intended to enhance the strength of the base fixing structure 100, further reduce the possibility of the base 20 falling off due to external force, and further achieve a stable installation and connection between the shell 10 and the base 20, thereby achieving a firm assembly effect.

[0056] There are two mounting holes 113, which are symmetrically arranged on opposite sides of the positioning column 114 along a second direction perpendicular to the first direction. There are two mounting claws 23, which are symmetrically arranged on the edge of the top surface 251 of the base 25, and the two mounting claws 23 are correspondingly engaged with the two mounting holes 113; the mounting boss 231 is the outer side surface of the mounting claw 23. It should be noted that the outer side surface of the mounting claw 23 refers to the side surface of the two symmetrically arranged mounting claws 23 that are away from each other. By setting the mounting claw 23 and the mounting hole 113 as a symmetrical structure, the assembly between the mounting claw 23 and the mounting hole 113 is faster, and the entire base 20 is more evenly stressed when supporting the shell 10, and the support is more stable.

[0057] In a specific embodiment, the groove A of the housing 10 is filled with foam, and the foam covers the connection structure 11 to fill the entire groove A. The foam is used to prevent dust and foreign matter from entering the groove A.

[0058] See also Figure 5 , Figure 5A schematic diagram of the structure of a base provided for an embodiment of the present application. The present application also provides a base 20. The base 20 includes a base body 25, a second boss 21, a second annular convex groove 22, and a mounting claw 23. The base body 25 has a top surface 251. The second boss 21 is arranged on the top surface 251, and a second reinforcing rib 211 is arranged on the side surface of the second boss 21. The second annular convex groove 22 is arranged on the top surface 251, and a first recessed portion 22a is arranged at the top of the groove wall of the second annular convex groove 22. The mounting claw 23 is arranged on the top surface 251 and is located between the second boss 21 and the same side of the second annular convex groove 22. The base body 25 has a positioning hole 24, and the positioning hole 24 is arranged between the second boss 21 and the second annular convex groove 22. There are two mounting claws 23, which are symmetrically arranged on the edge of the top surface 251 of the base 25 and are respectively located on opposite sides of the line connecting the second boss 21, the positioning hole 24 and the second annular convex groove 22. A mounting boss 231 is arranged on the outer side of the mounting claw 23. The mounting boss 231 is a three-dimensional structure with inclined outer sides, wherein the thickness of the mounting boss 231 gradually decreases in the direction away from the top surface 251 of the base 25. The mounting boss 231 is arranged in this way so that the mounting claw 23 can be installed more smoothly and quickly, so that the user only needs to use force in the last stage of the assembly process during installation, which is labor-saving and more convenient to install. The specific structure and beneficial effects are mentioned when introducing the base fixing structure 100, and will not be repeated here.
