[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the protection box for an external protective circuit board of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0022] See also Figures 1 to 5 The protective box for an external protective circuit board of the embodiment of the utility model comprises a shell 1, a baffle plate 11 is arranged in the shell 1, the baffle plate 11 divides the space in the shell 1 into a placement area 12 and a buffer area 13, the placement area 12 is provided with a fixing platform 14 for fixing the circuit board, and the four corners of the shell 1 are provided with a first fixing cylinder 15; a first cover plate 2 is used to cover the placement area 12; and a second cover plate 3 is used to cover the placement area 12 and the buffer area 13.

[0023] In the above embodiment, the main body of the protection box is composed of a shell 1, and a blocking plate 11 is arranged in the shell 1, which divides the internal space into a placement area 12 and a buffer zone 13. The placement area 12 is used to place the circuit board, and a fixing platform 14 is arranged inside, so that the circuit board can be firmly fixed after installation, avoiding shaking or displacement of the circuit board during transportation or use. At the same time, the design of the fixing platform 14 also allows the circuit board to maintain a certain height in the shell 1, and not directly contact the bottom of the shell 1, so that when the shell 1 is subjected to external impact, the circuit board can avoid direct force, reducing the risk of damage. The design of the buffer zone 13 is a part of the protection mechanism. It is located around the placement area 12 and provides an additional space barrier for the circuit board. When the protection box is subjected to external force impact, the buffer zone 13 can absorb and disperse part of the impact force, effectively alleviating the direct impact effect on the circuit board in the placement area 12. In addition, the first fixed cylinders 15 are installed at the four corners of the shell 1. These cylinders not only enhance the overall structural strength of the shell 1, but also play an important role in situations such as accidental falls. When the protection box accidentally falls to the ground, if one of the cylinders touches the ground first, its cylindrical shape can guide and change the direction of the impact force, thereby dispersing and weakening the direct impact of the impact force on the shell 1, and utilizing the impact force dispersion principle in mechanics to further enhance the safety of the circuit board. The double covering of the first cover plate 2 and the second cover plate 3 increases the stability of its connection and prevents the internal space of the shell 1 from being exposed when it falls. In summary, the external protective circuit board protection box is a reliable circuit board protection box through multiple designs such as double-layer covers, separated spaces, raised circuit boards, setting buffer zones 13, and enhancing the protection capabilities of the edges of the shell 1.

[0024] See also Figures 1 to 5 In another embodiment, the shell 1 is further provided with two semi-fixed cylinders 16, and the semi-fixed cylinder 16 is close to the first fixed cylinder 15, and the four corners of the first cover plate 2 are provided with second fixed cylinders 21, wherein when the first cover plate 2 covers the placement area 12, the second fixed cylinder 21 is opposite to the first fixed cylinder 15 and the semi-fixed cylinder 16, and the first cover plate 2 is closed with the blocking plate 11.

[0025] In the above embodiment, the shell 1 is further provided with two semi-fixed cylinders 16, which are tightly fitted to the side of the first fixed cylinder 15, forming an enhanced support and fixing structure. Such a design not only enhances the structural strength of the corners of the shell 1, but also provides more connection points and stability. The four corners of the first cover plate 2 are equipped with second fixed cylinders 21, which correspond one to one with the first fixed cylinder 15 and the semi-fixed cylinder 16 of the shell 1 in position. When the first cover plate 2 is covered on the placement area 12, the second fixed cylinder 21 will be closely opposite to the first fixed cylinder 15 and the semi-fixed cylinder 16 of the shell 1, and a stable connection is achieved through a locking mechanism (such as a thread, a buckle). In addition, the edge of the first cover plate 2 is designed with a profile that matches the baffle plate 11 to ensure that it can fit tightly during the covering process and achieve complete closure of the placement area 12.

[0026] See also Figures 1 to 5 In another embodiment, the four corners of the second cover plate 3 are each provided with a third fixed cylinder 31, wherein when the second cover plate 3 covers the buffer area 13 and the placement area 12, the third fixed cylinder 31 is opposite to the second fixed cylinder 21 and the first fixed cylinder 15.

[0027] In the above embodiment, when the second cover plate 3 covers the buffer zone 13 and the placement zone 12, the third fixed cylinders 31 at the four corners thereof will be opposite to the first fixed cylinders 15 at the corresponding positions below and the second fixed cylinders 21 of the first cover plate 2 (the first cover plate 2 has been installed). This relative arrangement allows the second cover plate 3 to be firmly fixed to the housing 1 through a locking mechanism (such as threaded connection, snap-on fixing) to form a complete closed space. The third fixed cylinder 31 not only provides a stable support point for the second cover plate 3, but also ensures that the entire protection box can maintain structural integrity and stability when subjected to external forces through mutual cooperation with other fixed cylinders. In addition, the arrangement of the third fixed cylinder 31 also enhances the seismic resistance of the protection box. When subjected to impact or vibration, these cylinders can disperse and absorb part of the energy, reduce the direct impact on the circuit board and its surrounding structures, and thus more effectively protect the safety of the circuit board.

[0028] See also Figures 1 to 5In another embodiment, the housing 1 is further provided with a wiring port 17 .

[0029] In the above embodiment, a wiring port 17 is specially provided on the housing 1. This allows the circuit board to be connected to an external device or power source.

[0030] See also Figures 1 to 5 In another embodiment, the housing 1 is further provided with a heat dissipation hole 18 .

[0031] In the above embodiment, the main function of the heat dissipation holes 18 is to promote air circulation inside and outside the housing 1 so as to effectively dissipate the heat generated by the circuit board when it is working.

[0032] See also Figures 1 to 5 In another embodiment, the buffer area 13 is provided with elastic cotton.

[0033] In the above embodiment, the softness and compressibility of the elastic cotton further enhance the shock absorption effect of the buffer zone 13. When the protection box is subjected to external impact, the elastic cotton can absorb and disperse the impact force, reducing the direct transmission of the impact force to the placement area 12 where the circuit board is located. At the same time, the elastic cotton can also effectively isolate external vibrations and provide a more stable working environment for the circuit board.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
