The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0057] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a connecting structure 2, which comprises a locking piece 110, a first connecting piece 21 and a second connecting piece 22.

[0058] Please refer to Figure 4 The locking piece 110 comprises a first limiting part 111, a connecting part 112 and a second limiting part 113 connected in sequence, wherein the outer diameter of the connecting part 112 is smaller than the outer diameter of the first limiting part 111 and the second limiting part 113. The material of the locking piece 110 can be plastic, metal, alloy and the like, and can be an integral structure, and the first limiting part 111, the connecting part 112 and the second limiting part 113 are integrally formed by injection molding or casting process. The locking piece 110 can also be a split structure, for example, the first limiting part 111 and the connecting part 112 are one part, and the second limiting part 113 is another part; the first limiting part 111 is one part, and the connecting part 112 and the second limiting part 113 are another part; the first limiting part 111, the connecting part 112 and the second limiting part 113 can also be different single parts. Herein, the material and form of the locking piece 110 are not limited.

[0059] Please refer to Figure 3 The first connecting piece 21 has a first fixing hole 120a, and the second connecting piece 22 has a second fixing hole 130a which is detachably matched with the first limiting part 111. At least the hole diameter of the first fixing hole 120a near one end of the second fixing hole 130a is smaller than the outer diameter of the first limiting part 111 and the outer diameter of the second limiting part 113, and is larger than the outer diameter of the connecting part 112. The material of the first connecting piece 21 and the second connecting piece 22 can be plastic material, such as but not limited to polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polycarbonate (PC) and the like, and the first fixing hole 120a and the second fixing hole 130a can be integrally formed by injection molding.

[0060] When assembling, when the locking piece 110 is an integrally formed component, because the first connecting piece 21 is plastic material, it has certain deformation ability, so the first limiting part 111 of the locking piece 110 can be forcibly threaded through the first fixing hole 120a, and then the second fixing hole 130a of the second connecting piece 22 is fixed relative to the first limiting part 111, at this time, under the common limiting of the first limiting part 111 and the second limiting part 113, the first connecting piece 21 and the second connecting piece 22 can be fixed relative to each other by the locking piece 110. Of course, when assembling, the first fixing hole 120a and the second fixing hole 130a can be aligned first, and then the locking piece 110 is threaded through the first fixing hole 120a and the second fixing hole 130a in sequence. When the locking piece 110 is a split component, the connecting part 112 can be threaded through the first fixing hole 120a first, and then the first limiting part 111 and / or the second limiting part 113 are fixed relative to the connecting part 112, at this time, the locking piece 110 can be assembled and fixed with the first connecting piece 21, and then the second connecting piece 22 can be assembled and fixed with the locking piece 110. It can be understood that when the locking piece 110 is a split structure, the first connecting piece 21 can be metal, alloy or hard plastic material.

[0061] When disassembling, the locking piece 110 is first disassembled from the second fixing hole 130a, at this time the first connecting piece 21 and the second connecting piece 22 can be disassembled, and because the outer diameter of the first limiting part 111 is smaller than the hole diameter of the first fixing hole 120a, the first limiting part 111 is limited in the first fixing hole 120a, so that the locking piece 110 can be prevented from being separated from the first connecting piece 21.

[0062] Based on the connecting structure 2 of the application, in the assembled state, the locking piece 110 is arranged through the first fixing hole 120a, and the first limiting part 111 is fixed in the second fixing hole 130a, so as to relatively fix the first connecting piece 21 and the second connecting piece 22, and in the disassembled state, the first limiting part 111 is disassembled from the second fixing hole 130a, so that the first connecting piece 21 and the second connecting piece 22 can be disassembled, and the first limiting part 111 is limited in the first fixing hole 120a, so as to prevent the locking piece 110 from being separated from the first connecting piece 21. This connection method is simple, and the locking piece 110 can be prevented from being lost after disassembly, thereby avoiding the possibility of being eaten by babies or pets. The first connecting piece 21 and the second connecting piece 22 can be injection molded parts, and this connecting structure 2 can be applied to the fields of toys, fans, battery boxes 10, etc. For example, some toys need to disassemble the shell to replace the first battery 140 or clean the internal parts, and the first connecting piece 21 and the second connecting piece 22 can be two shells respectively, and the two shells are fixed and disassembled by the locking piece 110. Similarly, when the fan needs to disassemble the shell to clean the fan blades, the front shell and the rear shell of the fan can be formed as the first connecting piece 21 and the second connecting piece 22 respectively, and the front shell and the rear shell are fixed and disassembled by the locking piece 110.

[0063] In a second aspect, referring to Figures 1 to 3 The application also provides a battery box 10 provided with the above connecting structure 2, wherein the first shell 120 forms the above first connecting piece 21 and has the first fixing hole 120a; the second shell 130 forms the above second connecting piece 22 and has the second fixing hole 130a, and next, the connecting structure 2 is described in detail taking the battery box 10 as an example. The second shell 130 is detachably connected with the first shell 120 and jointly defines the mounting cavity 120A, and the first battery 140 is mounted in the mounting cavity 120A. In this example, after the power of the first battery 140 is consumed, the first shell 120 and the second shell 130 can be disassembled by the locking piece 110, so that the first battery 140 in the mounting cavity 120A can be replaced, and the locking piece 110 will not be lost. After the user replaces the first battery 140, the locking piece 110 can be quickly fixed to the first shell 120 and the second shell 130 again to complete the assembly and fixation of the battery box 10.

[0064] Please refer to Figure 5In some embodiments, the second fixing hole 130a is a through hole, and the first limiting part 111 is in interference fit with the second fixing hole 130a. Optionally, the first limiting part 111 includes a rod body 1111 and a protruding piece 1112 protruding from the outer wall of the rod body 1111, and the protruding piece 1112 is detachably connected with the rod body 1111. The protruding piece 1112 can be in the form of a rod, a block, a plate, a ring, etc., and the connection mode of the protruding piece 1112 with the rod body 1111 includes but is not limited to clamping, threaded connection, sleeving, etc. For example, the sidewall of the rod body 1111 is provided with a clamping groove, and the protruding piece 1112 is provided with a clamping protrusion, and the clamping protrusion is buckled with the clamping groove to fix the protruding piece 1112 on the sidewall of the rod body 1111. In this way, the protruding piece 1112 is installed at one end of the rod body 1111, and the first limiting part 111 and the connecting part 112 are formed.

[0065] Optionally, the protruding piece 1112 is a limiting ring. The limiting ring is sleeved outside the rod body 1111, and the limiting ring can increase the contact area of the protruding piece 1112 with the first shell 120. It can be understood that, since the outer diameter of the first limiting part 111 is greater than the hole diameter of the first fixing hole 120a, the shell structure of the first shell 120 has a limiting effect, and the limiting ring abutting on the first shell 120 has a larger contact area with the first shell 120, so that the locking piece 110 is less likely to loosen or fall off.

[0066] In order to improve the stability of the fixed limiting ring, please continue to refer to Figure 5 The outer wall of the rod body 1111 is provided with a groove 1113, and part of the limiting ring is embedded in the groove 1113 and part of the limiting ring is exposed outside the groove 1113. The limiting ring can be made of silica gel, rubber or the like, which has a certain deformation capacity, so that the limiting ring can better adapt to the shape and size of the hole wall when it is in interference fit with the second fixing hole 130a, thereby ensuring the tightness and stability of the connection. At the same time, these materials also have certain wear resistance and corrosion resistance, which can prolong the service life of the limiting ring.

[0067] In some embodiments, the second fixing hole 130a is a threaded hole, please refer to Figure 4The first limiting portion 111 includes a rod body 1111 and external threads protruding from the outer wall of the rod body 1111, and is threadedly connected with the second fixing hole 130a. In this example, the external threads protrude outward from one end of the rod body 1111, and the portion with the external threads is the first limiting portion 111, and the portion without the external threads is the connecting portion 112. Further, a protruding structure is arranged at the end of the rod body 1111 away from the external threads, thereby forming the second limiting portion 113. In this way, the locking member 110 of the present application can be an integral structure, and can be a screw structure with a portion having threads and a portion not having threads. The first limiting portion 111 is threadedly connected with the second fixing hole 130a, and has good self-locking performance, and can maintain the stability of the connection even in a vibrating or impacting environment. Further, a common screwdriver slot type such as a cross slot or a slot can be arranged on the second limiting portion 113, and a user can easily rotate the locking member 110 out of the second fixing hole 130a using a screwdriver or other tool, thereby achieving disassembly.

[0068] Please refer to Figure 3 In some embodiments, the first fixing hole 120a includes a first hole section 120b and a second hole section 120c connected with each other, the first hole section 120b is closer to the second fixing hole 130a than the second hole section 120c, and the hole diameter of the second hole section 120c is smaller than the outer diameter of the first limiting portion 111. The hole diameter of the second hole section 120c gradually increases in the direction away from the first hole section 120b, thereby forming a guide surface 126. In the case where the locking member 110 is integrally formed, the locking member 110 can more smoothly enter the second hole section 120c through the guide surface 126, thereby reducing the installation difficulty and the required force of the locking member 110.

[0069] Further, the maximum hole diameter of the second hole section 120c is greater than the outer diameter of the first limiting portion 111. During installation, the first limiting portion 111 can directly abut against the guide surface 126, and then be forcibly inserted along the guide surface 126 until the first limiting portion 111 passes through the first fixing hole 120a.

[0070] Further, the outer diameter of the first limiting portion 111 is not greater than 1.3 times the hole diameter of the first hole section 120b. In this example, the locking member 110 encounters relatively small resistance during installation, thereby reducing the friction and extrusion caused by the forcible insertion, and reducing the abrasion and damage to the first shell 120, maintaining the structural integrity of the first shell 120, and preventing the deformation or rupture of the first shell 120 caused by stress concentration during installation. For example, when the hole diameter of the first hole section 120b is 5 mm, the outer diameter of the first limiting portion 111 can be 5.4 mm to 6.5 mm; when the hole diameter of the first hole section 120b is 6 mm, the outer diameter of the first limiting portion 111 can be 6.4 mm to 7.8 mm.

[0071] Referring to Figure 3 In some embodiments, the second fixing hole 130a comprises a third hole segment 130b and a fourth hole segment 130c connected to each other, the third hole segment 130b is closer to the first hole segment 120b than the fourth hole segment 130c; wherein the hole diameter of the third hole segment 130b is greater than the outer diameter of the first limiting part 111, and in the assembled state, the fourth hole segment 130c is fixedly matched with the first limiting part 111.

[0072] Referring to Figure 3 In order to facilitate the molding of the first fixing hole 120a and the second fixing hole 130a, the first shell 120 of the embodiment of the application comprises a first shell outer wall 121 and a first fixing column 122, the first fixing column 122 is connected to the inner wall surface of the first shell outer wall 121 and extends into the mounting cavity 120A, the first fixing column 122 and the first shell outer wall 121 cooperatively define the first fixing hole 120a; the second shell 130 comprises a second shell outer wall 131 and a second fixing column 132, the second fixing column 132 is connected to the inner wall surface of the second shell outer wall 131 and extends into the mounting cavity 120A, the second fixing column 132 is provided with the second fixing hole 130a. In this example, due to the extension of the fixing column, the contact area between the locking piece 110 and the shell can be increased, thereby improving the stability of the connection, preventing the locking piece 110 from loosening or falling off in a vibrating or impacting environment, and also increasing the structural strength of the shell. Further, the first hole segment 120b of the first fixing hole 120a can be provided on the first fixing column 122, so that in the process of forcibly threading the locking piece 110, damage to the first shell outer wall 121 can be avoided.

[0073] It can be understood that the first fixing column 122 and the second fixing column 132 of the application are arranged in alignment in the thickness direction of the battery box 10, so that the first fixing hole 120a and the second fixing hole 130a are arranged in alignment, and the end surface of the first fixing column 122 and the end surface of the second fixing column 132 can be arranged in abutting state, or the gap between the two is relatively small, so that in the assembled state, the first fixing column 122 and the second fixing column 132 can mostly cover the locking piece 110, reducing the possibility of the locking piece 110 contacting the internal components, and improving the stability of the battery box 10.

[0074] Further, the second fixing hole 130a includes a third hole segment 130b and a fourth hole segment 130c connected with each other. Since the end face of the first fixing column 122 and the end face of the second fixing column 132 can be arranged in an abutting state or the gap therebetween is relatively small, the third hole segment 130b of the present application can be an avoiding interval, that is, the lock piece 110 is withdrawn from the fourth hole segment 130c to realize the disassembly of the first shell 120 and the second shell 130.

[0075] The outer contour of the second limiting portion 113 is adapted to the inner contour of the second hole segment 120c. In the assembled state, the second limiting portion 113 is accommodated in the second hole segment 120c. In this example, the accommodation of the second limiting portion 113 in the second hole segment 120c can prevent the second limiting portion 113 from being directly impacted or damaged by the external environment, avoid the lock piece 110 from loosening or falling off in a vibration or impact environment, thereby improving the stability of the overall structure, and also prevent dust, moisture or other pollutants from entering the inside of the battery box 10 from the first fixing hole 120a.

[0076] Referring to Figure 1 , the second shell 130 includes an assembly portion 134 and a folding portion 135. The assembly portion 134 is fixedly connected with the first shell 120, and the folding portion 135 can be folded about the connection with the assembly portion 134 and is detachably connected with the first shell 120 to open or close the mounting cavity 120A.
