[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Reference Figure 1-6 As shown, the box structure provided by the embodiment of the utility model is shown, which includes an installation box 1, a circuit board 2 and a cover plate 3; the installation box 1 is provided with an opening 11, the circuit board 2 is located in the installation box 1, the cover plate 3 is covered at the opening 11, and the circuit board 2 and the cover plate 3 are both snap-connected with the installation box 1. Specifically, when installing the circuit board 2, the circuit board 2 can be placed in the installation box 1 from the opening 11, and then the circuit board 2 and the installation box 1 are fixed by snap-connection. Similarly, when installing the cover plate 3, the cover plate 3 can be placed at the opening 11, and then the cover plate 3 and the installation box 1 are fixed by snap-connection. In this way, the installation of the circuit board 2 and the cover plate 3 is realized. It can be seen from the above that the circuit board 2 and the cover plate 3 do not need to be fixed with screws as in the prior art during installation, so the step of tightening the screws is also omitted, making the installation very convenient. Similarly, when disassembling, it is only necessary to apply external force to release the snap connection without the need to tighten the screws.

[0027] In some embodiments, the snap-fit ​​connection between the circuit board 2 and the mounting box 1 is achieved in the following manner: a plurality of first brackets 12 and a plurality of first limiting posts 13 are provided in the mounting box 1, and each first bracket 12 is used to provide a first supporting force to the circuit board 2 so as to support the circuit board 2 on the mounting box 1; each first limiting post 13 is used to limit the displacement of the circuit board 2 along the direction of the first supporting force.

[0028] Among them, the first bracket 12 actually limits the displacement of the circuit board 2 in the opposite direction of the first supporting force, and the first limiting column 13 limits the displacement of the circuit board 2 in the direction of the first supporting force. Therefore, the circuit board 2 can be limited and fixed by the displacement restrictions in the above two directions.

[0029] For the sake of convenience, the side of the first limit post 13 facing the bottom of the installation box 1 is called the inner side, and the side of the first limit post 13 facing the opening 11 of the installation box 1 is called the outer side. In this way, the installation process of the circuit board 2 is as follows: push the circuit board 2 from the opening 11 of the installation box 1 toward the bottom of the installation box 1 until the circuit board 2 abuts against the first bracket 12. At this time, the first bracket 12 supports the circuit board 2 to prevent the circuit board 2 from further displacement. At the same time, the edge of the circuit board 2 will also slide from the outer side of the first limit post 13 to the inner side of the first limit post 13. The whole process can actually be regarded as the circuit board 2 being stuck in the space between the first bracket 12 and the first limit post 13, that is, the snap connection between the circuit board 2 and the installation box 1 is realized.

[0030] It should be noted that the number of the first limit clamping column 13 can be set according to actual needs, as long as it can meet the above-mentioned limit function. Figure 4-5 As shown, the number of the first limiting posts 13 is set to three, and the installation box 1 has a bottom surface and four circumferential surfaces. Two first limiting posts 13 are arranged on one of the circumferential surfaces, and the remaining first limiting post 13 is arranged on the circumferential surface opposite to the circumferential surface.

[0031] In some embodiments, each first bracket 12 is also suitable for limiting the displacement of the circuit board 2 in a direction perpendicular to the first supporting force. In this way, the circuit board 2 can be further fixed to prevent the circuit board 2 from shaking in the installation box 1. Specifically, each first bracket 12 includes a support portion 121, the first end of the support portion 121 is fixedly connected to the box body, and the second end of the support portion 121 abuts against the circuit board 2 to support the circuit board 2. The circuit board 2 is provided with a number of bar holes 21 equal to the number of the first brackets 12, and each first bracket 12 also includes a limiting portion 122, each limiting portion 122 is arranged one-to-one at the second end of each supporting portion 121, and each limiting portion 122 can pass through each bar hole 21 one-to-one to limit the displacement of the circuit board 2 in a direction perpendicular to the first supporting force. In other words, in the above-mentioned setting method, the limiting portion 122 can pass through the bar hole 21, while the supporting portion 121 cannot pass through it. In this way, the first bracket 12 realizes the support of the circuit board 2 and the limitation of the displacement of the circuit board 2 in a direction perpendicular to the first supporting force. In addition, the displacement of the circuit board 2 in a direction perpendicular to the first supporting force can be limited by providing the same number of notches as the first brackets 12 on the circuit board 2 and accommodating the second ends of the first brackets 12 in the corresponding notches. Alternatively, the displacement of the circuit board 2 in a direction perpendicular to the first supporting force can be limited by magnetically attracting the second ends of the first brackets 12 to the circuit board.

[0032] In some embodiments, reference Figure 6 , a guide surface 131 is provided on the side of each first limit post 13 away from the circuit board 2. That is, the guide surface 131 is provided on the outer side of the first limit post 13. Through such a setting, the circuit board 2 can be easily slid from the outer side of the first limit post 13 to the inner side, making installation more convenient.

[0033] In some embodiments, the snap connection between the cover plate 3 and the installation box 1 is achieved in the following manner: a plurality of second brackets 32 and a plurality of second position-limiting posts 14 are provided in the installation box 1, and each second bracket 32 ​​is used to provide a second supporting force to the cover plate 3 to support the cover plate 3; each second position-limiting post 14 is used to limit the displacement of the cover plate 3 in the direction of the second supporting force. Specifically, the cover plate 3 is provided with hooks 31 equal in number to the second position-limiting posts 14, and each hook 31 is suitable for hooking with each second position-limiting post 14 in a one-to-one correspondence to limit the displacement of the cover plate 3 in the direction of the second supporting force; each second bracket 32 ​​is provided on the cover plate 3, and each second bracket 32 ​​is also suitable for abutting against the circuit board 2 to support the cover plate 3; or each second bracket 32 ​​is provided on the installation box, and each second bracket 32 ​​is suitable for abutting against the cover plate 3 to support the cover plate 3.

[0034] Among them, the second bracket 32 ​​actually limits the displacement of the cover plate 3 in the opposite direction of the second supporting force, and the hook connection between the second limiting clamping column 14 and the hook 31 limits the displacement of the cover plate 3 in the direction of the second supporting force. Therefore, the cover plate 3 can be limited and fixed by the displacement limitation in the above two directions.

[0035] The installation process of the cover 3 is as follows: cover the cover 3 on the opening 11 of the installation box 1, and apply a thrust toward the bottom of the installation box 1 to the cover 3 to displace the cover 3 in the direction of the thrust until the second bracket 32 ​​abuts against the circuit board 2. At this time, the second bracket 32 ​​supports the cover 3 and prevents the cover 3 from continuing to move. At the same time, the hook 31 on the cover 3 will also be hooked with the second limit post 14, thereby realizing a snap connection between the circuit board 2 and the installation box 1.

[0036] It should be noted that the number of the second limit clamping column 14 can be set according to actual needs, as long as it can meet the above-mentioned limit function. Figure 4-5 As shown, the number of the second limit posts 14 is set to four, and the installation box 1 has a bottom surface and four circumferential surfaces. Two second limit posts 14 are arranged on one of the circumferential surfaces, and the other two second limit posts 14 are arranged on the circumferential surface opposite to the circumferential surface. It should be noted that the shape of the second bracket 32 ​​is not limited in the utility model, as long as it can achieve the supporting function.

[0037] In some embodiments, at least one first limit post 13 and one second limit post 14 are arranged on the same straight line in the direction of ejection of the mounting box 1. In this way, it is convenient to open the mold. Figure 4-5 In this embodiment, the number of the first limit posts 13 is set to three, the number of the second limit posts 14 is set to four, the installation box 1 has a bottom surface and four circumferential surfaces, wherein two first limit posts 13 and two second limit posts 14 are arranged on one of the circumferential surfaces. For the convenience of description, this circumferential surface is now referred to as the first circumferential surface, and the remaining first limit post 13 and the remaining two second limit posts 14 are arranged on the second circumferential surface opposite to the first circumferential surface. The two first limit posts 13 and the two second limit posts 14 on the first circumferential surface are arranged as follows: Figure 4 As shown, they can be connected into two straight lines that are the same as the demoulding direction of the installation box 1.

[0038] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
