Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a heat dissipation component and an energy storage inverter device. Background Technology

[0002] Energy storage inverters are equipped with fans that require regular replacement and maintenance. To protect the fans, they are often housed within the inverter's casing, increasing the difficulty of maintenance. In related technologies, fans are typically mounted within a fan bracket, which is movably mounted within the inverter's casing. This allows for easy maintenance by pulling out the fan bracket. However, this pull-out method requires a significant degree of freedom of movement between the fan bracket and the inverter's casing, resulting in poor fan stability. Consequently, the fan can easily cause the fan bracket to shake during operation, generating considerable noise. Utility Model Content

[0003] In view of this, this application provides a heat dissipation component and an energy storage inverter device, which can facilitate fan maintenance while reducing fan noise during operation.

[0004] In a first aspect, one embodiment of this application provides a heat dissipation component applied to an energy storage inverter device. The energy storage inverter device includes a main unit and a junction box. The main unit is provided with a heat sink. The junction box is connected to the main unit and has a flip cover. The heat dissipation component includes a protective box, a mounting structure, and a fan. The protective box is fixedly connected to the flip cover and moves synchronously with the flip cover's flipping action. The protective box has ventilation holes. The mounting structure is configured to be fixed to the protective box or the main unit. The fan is fixed to the mounting structure. When the flip cover is in the closed state, the protective box covers the fan, the fan faces the heat sink, and can generate airflow through the heat sink and ventilation holes. When the flip cover is flipped to the open state, the protective box moves with the flip cover to expose the fan.

[0005] The fan of this application is fixed to the protective box or the host through the mounting structure, and the protective box is fixed to the flip cover and moves synchronously with the flip cover. When the flip cover is closed, the fan and the mounting structure can be fixed relative to the protective box or the host when the fan is running, so as to improve the problem of easy shaking of the mounting structure and the fan, thereby reducing the noise generated by the fan when it is running. At the same time, the protective box is fixed on the flip cover. When the flip cover is opened, the protective box moves to expose the fan, which is convenient for fan maintenance.

[0006] In at least one embodiment, the mounting structure includes a mounting bracket, which is fixed to the host and located on one side of the heat sink, and the mounting bracket also fixes the fan; when the flip cover is in the closed state, the protective box is located on the side of the fan away from the heat sink and covers the fan.

[0007] The fan is mounted on the host unit using a fixed bracket. Since the heatsink is also located on the host unit, the distance between the fan and the heatsink is short, resulting in less airflow attenuation and more concentrated airflow. This leads to better heat dissipation from the fan on the heatsink. Furthermore, when the flip cover is closed, the protective box covers the fan, and the airflow through the ventilation holes in the protective box promotes airflow convection, thereby improving heat dissipation. The protective box also protects the fan, reducing the amount of dust and condensation entering it. Moreover, the protective box does not move the fan when the flip cover moves, keeping the fan in a stable and fixed position, thus reducing noise caused by unstable fan mounting.

[0008] In at least one embodiment, the fixed bracket includes a bracket body, a limiting part, and a fixing part. The bracket body is fixed to the fan, the limiting part is disposed on the bracket body and configured to cooperate with the host in a limiting manner, and the fixing part is disposed on the bracket body and configured to be fixedly connected to the host.

[0009] By using the limiting part to limit the main unit, the installation position of the fixed bracket and the main unit can be quickly positioned, thereby improving the efficiency of installing the fixed bracket on the main unit.

[0010] In at least one embodiment, the mounting structure further includes two limiting ribs, both of which are fixed to the main unit and located on opposite sides of the support body. There are two limiting parts, which are respectively connected to opposite sides of the support body and correspond one-to-one with the two limiting ribs. Each limiting part includes a first limiting segment and a second limiting segment, which are connected and set at an included angle. The first limiting segment and the second limiting segment abut against different directions of the limiting ribs.

[0011] By configuring the limiting part into a structure including a first limiting segment and a second limiting segment, with the first and second limiting segments respectively abutting against different directions of the limiting rib, rapid positioning between the fixed bracket and the main unit is achieved, improving the assembly efficiency of the fixed bracket and the main unit. Furthermore, the first and second limiting segments limit the limiting rib in two different directions, reducing the swaying of the fixed bracket in both directions, thereby improving the installation stability of the fixed bracket. In addition, the limiting part and the limiting rib on the main unit of this application are provided with two, and the two limiting parts form a positioning line, thereby further improving the positioning effect and installation stability of the fixed bracket.

[0012] In at least one embodiment, the protective box has a communicating opening, which and the ventilation hole are located on opposite sides of the protective box. The mounting structure includes a support rib located inside the protective box and configured to fix the fan so that when the flip cover is closed, the communicating opening is directly opposite the heat sink, so that the fan is directly opposite the heat sink.

[0013] By fixing the fan inside the protective box, the protective box and the fan remain relatively fixed as the protective box moves with the flip cover, and the protective box always protects the fan. This improves the situation where the fan and the protective box are prone to collisions during the movement of the protective box, and enhances the reliability of the protective box and the fan.

[0014] In at least one embodiment, the mounting structure further includes multiple fixing posts, each fixed to the supporting rib and the peripheral edge of the fan. The multiple fixing posts and the supporting rib are connected to form a whole, improving the structural strength of the supporting rib and the fixing posts. Each fixing post supports the fan and is fixedly connected to it. The multiple fixing posts form a fixing surface or fixing line to improve the stability of the fan installed within the protective box.

[0015] In at least one embodiment, the mounting structure includes a plurality of connecting ribs, at least some of which connect to the supporting ribs and the inner wall of the protective box, and the plurality of connecting ribs are spaced apart along the circumference of the fan.

[0016] By setting multiple connecting ribs, the structural strength between the protective box and the supporting ribs can be increased, and the structural stability of the supporting ribs inside the protective box can be improved.

[0017] In at least one embodiment, the heat dissipation assembly further includes a connecting post, which is fixed to the flip cover. The protective box is provided with a fixing hole, and the connecting post is fixedly engaged with the fixing hole to fix the protective box and the flip cover.

[0018] By setting fixing holes in the protective box, the flip cover is fixedly connected with connecting posts. The connecting posts can be inserted through the fixing holes to facilitate the installation and positioning between the protective box and the flip cover, so as to achieve quick installation of the protective box and the flip cover.

[0019] In at least one embodiment, the fixing hole includes a first hole and a second hole, the first hole and the second hole are connected, the diameter of the first hole is larger than the diameter of the second hole, the connecting post enters the second hole through the first hole, and the wall of the second hole is interference-fitted with the connecting post.

[0020] Because the first hole has a larger diameter, it is convenient for the connecting post to enter, thereby enabling the quick positioning of the connecting post and the protective box and improving the assembly efficiency of the protective box. The connecting post enters the second hole through the first hole, and the wall of the second hole is interference-fitted with the connecting post, thereby achieving a fixed connection between the protective box and the flip cover, making the connection between the protective box and the flip cover stable.

[0021] Secondly, embodiments of this application provide an energy storage inverter device, which includes a junction box, a main unit, and the aforementioned heat dissipation assembly; the junction box is provided with a flip cover, and the protective box of the heat dissipation assembly is fixed to the flip cover and moves synchronously with the rotation of the flip cover; the junction box is located at one end of the main unit, the main unit is provided with a heat sink, and the fan of the heat dissipation assembly is installed on the main unit or the protective box, with the fan located on one side of the heat sink.

[0022] By incorporating the aforementioned heat dissipation components into the energy storage inverter, when the flip cover is closed and the fan is running, the fan and mounting structure can remain stationary relative to the protective box or the main unit. This improves the problem of the mounting structure and fan easily wobbling, thereby reducing the noise generated during fan operation. Meanwhile, the protective box is fixed to the flip cover. Opening the flip cover moves the protective box to expose the fan, facilitating fan maintenance. Attached Figure Description

[0041] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0043] Energy storage inverters are equipped with fans, which require regular replacement and maintenance. To protect the fans, they are often housed within the inverter's casing, increasing the difficulty of maintenance. In related technologies, fans are typically mounted within a fan bracket, which is movably mounted within the inverter's casing for easy maintenance by pulling it out. However, this pull-out method requires significant freedom of movement between the fan bracket and the inverter's casing. Furthermore, when the fan is closed and operating, its stability is poor, and the fan bracket is prone to wobbling, resulting in considerable noise.

[0044] This application provides a heat dissipation component applied to an energy storage inverter device. The energy storage inverter device includes a main unit and a junction box. The main unit is equipped with a heat sink. The junction box is connected to the main unit and has a flip cover. The heat dissipation component includes a protective box, a mounting structure, and a fan. The protective box is fixedly connected to the flip cover and moves synchronously with the flip cover's flipping action. The protective box has ventilation holes. The mounting structure is configured to be fixed to the protective box or the main unit. The fan is fixed to the mounting structure. When the flip cover is in the closed state, the protective box covers the fan, the fan faces the heat sink, and can generate airflow through the heat sink and ventilation holes. When the flip cover is flipped to the open state, the protective box moves with the flip cover to expose the fan.

[0045] The fan of this application is fixed to the protective box or the host through the mounting structure, and the protective box is fixed to the flip cover and moves synchronously with the flip cover. When the flip cover is closed, the fan and the mounting structure can be fixed relative to the protective box or the host when the fan is running, so as to improve the problem of easy shaking of the mounting structure and the fan, thereby reducing the noise generated by the fan when it is running. At the same time, the protective box is fixed on the flip cover. When the flip cover is opened, the protective box moves to expose the fan, which is convenient for fan maintenance.

[0046] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] Please see Figure 1 and Figure 2 The embodiments of this application provide a heat dissipation component 100 and an energy storage inverter device 200.

[0048] The energy storage inverter 200 includes a battery pack (not shown) to enable it to store and discharge electricity for use as backup power for homes, production facilities, outdoor work, and outdoor recreation.

[0049] In some embodiments, the energy storage inverter device 200 includes an inverter module (not shown). Exemplarily, the inverter module generally also includes electrical components such as a control circuit board and power devices to achieve the conversion between direct current and alternating current. Energy storage devices equipped with inverter modules can be small portable power banks, residential energy storage power supplies, industrial and commercial energy storage power supplies, or containerized energy storage power supplies, etc.

[0050] Please see Figure 1 and Figure 2 In some embodiments, the energy storage inverter device 200 includes a host 201, which is provided with a heat sink 203. The function of the heat sink 203 is to dissipate the heat generated by the host 201.

[0051] Please see Figure 1 and Figure 2 In some embodiments, the heat dissipation component 100 is applied in the energy storage inverter device 200. The heat dissipation component 100 includes a fan 30, which is disposed on one side of the heat sink 203 to increase the air flow through the airflow generated by the fan 30, accelerate the heat dissipation of the heat sink 203, and thereby improve the heat dissipation effect on the host 201.

[0052] Please see Figure 2 and Figure 4 In some embodiments, the energy storage inverter device 200 includes a junction box 202, which is connected to the host 201 and located at one end of the host 201. The junction box 202 is used to connect an external wiring harness to electrically connect with an external device, such as an energy storage power supply, mains power, or a photovoltaic panel.

[0053] Please see Figure 2 and Figure 4 In some embodiments, the junction box 202 includes a flip cover 2020 and a box body 2021, which are rotatably connected so that the flip cover 2020 has a closed state with the box body 2021 closed or an open state with the box body 2021 open.

[0054] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the heat dissipation assembly 100 includes a protective box 10 and a mounting structure 20. The protective box 10 is fixed to the flip cover 2020 and moves synchronously with the flip cover 2020 when it is flipped. The protective box 10 is provided with ventilation holes 110. The mounting structure 20 is configured to be fixed to the protective box 10 or the main unit 201. The fan 30 is fixed to the mounting structure 20. When the flip cover 2020 is in the closed state, the protective box 10 covers the fan 30. The fan 30 faces the heat sink 203 and can generate airflow through the heat sink 203 and the ventilation holes 110, thereby improving airflow. The fluidity accelerates the heat dissipation of the heat sink 203, improving the heat dissipation effect. Furthermore, since the fan 30 of this application is fixed to the protective box 10 or the host 201 by the mounting structure 20, and the protective box 10 is fixed to the flip cover 2020 and moves synchronously with the flip cover 2020, when the flip cover 2020 is in the closed state, when the fan 30 is running, the fan 30 and the mounting structure 20 can be fixed relative to the protective box 10 or the host 201, thereby improving the problem of easy shaking of the mounting structure 20 and the fan 30, and reducing the noise generated by the fan 30 during operation.

[0055] When the flip cover 2020 is flipped to the open state, the protective box 10 moves with the flip cover 2020 to expose the fan 30, so as to facilitate the disassembly, assembly and maintenance of the fan 30, thereby facilitating the maintenance of the fan 30.

[0056] Please see Figure 2 and Figure 3 In some embodiments, the energy storage inverter device 200 includes a decorative cover 205, which covers the heat sink 203 and at least part of the protective box 10 and is connected to the host 201, thereby hiding the heat sink 203 and at least part of the protective box 10. The decorative cover 205 can protect the heat sink 203 and the protective box. When the fan 30 is located on the host 201, the decorative cover 205 can also hide the fan 30 and protect the fan 30.

[0057] Understandably, when the fan 30 is located inside the protective box 10, the decorative cover 205 and the protective box 10 can work together to protect the fan 30.

[0058] Please see Figure 4 , Figure 6 and Figure 7 In some embodiments, the mounting structure 20 includes a fixing bracket 21, which is fixed to the host 201 and located on one side of the heat sink 203. The fixing bracket 21 fixes the fan 30. When the flip cover 2020 is in the closed state, the protective box 10 is located on the side of the fan 30 away from the heat sink 203 and covers the fan 30.

[0059] The fan 30 is mounted on the host 201 via a mounting bracket 21. Since the heat sink 203 is also located on the host 201, the distance between the fan 30 and the heat sink 203 is relatively short, resulting in less airflow attenuation from the fan 30 and more concentrated airflow. This improves the cooling effect of the fan 30 on the heat sink 203. Furthermore, when the flip cover 2020 is closed, the protective box 10 covers the fan 30, and the ventilation holes 110 of the protective box 10 facilitate airflow convection, thereby enhancing the cooling effect. The protective box 10 also protects the fan 30, reducing the entry of dust and condensation. Moreover, when the protective box 10 moves with the flip cover 2020, it does not move the fan 30, keeping the fan 30 in a stable and fixed state, thus reducing noise caused by unstable fixing of the fan 30.

[0060] In some embodiments, when the flip cover 2020 is in the closed state, the protective box 10 faces the side of the fan 30 away from the heat sink 203, so that the protective box 10 can completely cover the fan 30 and improve the shielding effect of the protective box 10 on the fan 30.

[0061] Understandably, when the flip cover 2020 is in the open state, the protective box 10 and the fan 30 are misaligned to avoid the fan 30, thereby exposing the fan 30 to the host 201, which facilitates the disassembly, assembly and maintenance of the fan 30.

[0062] Please see Figure 4 , Figure 7 and Figure 10 In some embodiments, the host 201 has an assembly space 2011 and an assembly opening 2012. The assembly space 2011 is connected to the heat sink 203, and the assembly opening 2012 is disposed opposite to the heat sink 203 and connected to the assembly space 2011. The protective box 10 has a connecting opening 120. When the fixing bracket 21 is fixed in the assembly space 2011 and the fan 30 is fixed to the fixing bracket 21; wherein, when the flip cover 2020 is in the closed state and the protective box 10 covers the fan 30, the protective box 10 covers the assembly opening 2012, and the connecting opening 120 is aligned with the assembly opening 2012 so that the airflow generated by the fan 30 can flow to the ventilation hole 110 of the protective box 10; when the flip cover 2020 is in the open state, the connecting opening 120 is misaligned with the assembly opening 2012 so that the fan 30 is exposed to the outside through the assembly opening 2012, so as to facilitate the installation and removal of the fan 30 through the assembly opening 2012.

[0063] Please see Figure 9 and Figure 10 In some embodiments, the mounting bracket 21 includes a bracket body 210, a limiting part 211, and a fixing part 212. The bracket body 210 is fixed to the fan 30. The limiting part 211 is disposed on the bracket body 210 and configured to limit and cooperate with the host 201. The fixing part 212 is disposed on the bracket body 210 and configured to be fixedly connected to the host 201. Through the limiting cooperation between the limiting part 211 and the host 201, the installation position of the mounting bracket 21 and the host can be quickly positioned, thereby improving the efficiency of installing the mounting bracket 21 on the host.

[0064] In some embodiments, multiple fixing parts 212 are provided, and the multiple fixing parts 212 are distributed on both sides of the bracket body 210 along the distribution direction of the fan 30 and the heat sink 203, so that both sides of the bracket body 210 are fixedly connected to the host 201, thereby improving the stability of the connection between the bracket body 210 and the host 201.

[0065] Each fixing part 212 includes a mounting hole, and a fastener passes through the mounting hole and the main unit 201 to fix the fixing bracket 21 to the main unit 201. For example, the fastener can be a screw or a bolt to enable the fixing bracket 21 to be disassembled and assembled, so as to facilitate the maintenance of the fixing bracket 21 and the fan 30 installed on the fixing bracket 21.

[0066] Please see Figure 10In some embodiments, the bracket body 210 has an installation space 2101. A boss 213 is provided on the inner wall of the bracket body 210 near the heat sink 203. At least a portion of the fan 30 is disposed within the installation space 2101 and abuts against the boss 213. The mounting structure 20 also includes a first fastener 24, and the fan 30 and the boss 213 are fixedly connected by the first fastener 24. The installation space 2101 allows for quick positioning of the fan 30, improving the assembly efficiency of mounting the fan 30 onto the bracket body 210.

[0067] For example, multiple installation spaces 2101 are provided, and each installation space 2101 is provided with a fan 30. The shape of each installation space 2101 is similar to the shape of the fan 30 to quickly locate the position of the fan 30 and realize the rapid assembly of the fan 30.

[0068] Each installation space 2101 is provided with multiple protrusions 213, which are spaced apart along the circumference of the fan 30. A fan 30 is abutted against multiple protrusions 213. Multiple first fasteners 24 are provided. In each installation space 2101, multiple first fasteners 24 are connected to multiple protrusions 213 in a one-to-one correspondence, so that multiple first fasteners 24 form a fixing surface, thereby improving the fixing stability of the fan 30.

[0069] For example, the first fastener 24 may be a screw or bolt to enable the disassembly and assembly of the fan 30, facilitating the maintenance of the fan 30.

[0070] Please see Figure 7 and Figure 8In some embodiments, the mounting structure 20 further includes two limiting ribs 2010, both of which are fixed to the host 201 and located on opposite sides of the bracket body 210. There are two limiting portions 211, each connected to opposite sides of the bracket body 210 and corresponding to one of the two limiting ribs 2010. Each limiting portion 211 includes a first limiting segment 2111 and a second limiting segment 2112, which are connected and angled together. The limiting ribs 2010 abut against each other in different directions, thereby achieving rapid positioning between the fixed bracket 21 and the main unit 201, improving the assembly efficiency of the fixed bracket 21 and the main unit 201. Furthermore, the first limiting segment 2111 and the second limiting segment 2112 limit the limiting ribs 2010 in two different directions, which can reduce the swaying of the fixed bracket 21 in two directions, thereby improving the installation stability of the fixed bracket 21. In addition, the limiting part 211 of this application and the limiting ribs 2010 on the main unit 201 are provided in two ways, and the two limiting parts 211 form a positioning line, thereby further improving the positioning effect and installation stability of the fixed bracket 21.

[0071] In some embodiments, the first limiting segment 2111 and the second limiting segment 2112 are integrally formed structures. The integrally formed structure ensures that there is no physical interruption between the first limiting segment 2111 and the second limiting segment 2112, thereby improving the structural strength of the limiting part 211.

[0072] Please see Figure 4 , Figure 11 and Figure 12 In some embodiments, the protective box 10 is provided with a communicating opening 120, which and the ventilation hole 110 are respectively located on opposite sides of the protective box 10. The mounting structure 20 includes a support rib 221, which is located inside the protective box 10 and is configured to fix the fan 30 so that when the flip cover 2020 is in the closed state, the communicating opening 120 is directly opposite the heat sink 203, so that the fan 30 is directly opposite the heat sink 203, thereby accelerating the heat dissipation of the heat sink 203 and improving the heat dissipation effect.

[0073] Understandably, when the flip cover 2020 is closed, the connecting opening 120 is directly opposite the assembly opening 2012 of the host 201 and connected to the assembly space 2011, so that the fan 30 located in the protective box 10 is connected to the heat sink 203, and the airflow generated by the fan 30 generates airflow between the heat sink 203 and the fan 30, which accelerates the heat dissipation of the heat sink 203 and improves the heat dissipation effect.

[0074] By fixing the fan 30 inside the protective box 10, the protective box 10 and the fan 30 remain relatively fixed during the flipping movement of the protective box 10 with the flip cover 2020, and the protective box 10 always protects the fan 30. This improves the situation where the fan 30 and the protective box 10 are prone to collision during the movement of the protective box 10, and enhances the reliability of the use of the protective box 10 and the fan 30.

[0075] Understandably, when the flip cover 2020 is in the open state, the connecting opening 120 and the assembly opening 2012 are misaligned so that the fan 30 is exposed to the outside through the connecting opening 120, so that the fan 30 can be disassembled and assembled through the connecting opening 120.

[0076] Please see Figure 11 and Figure 12 In some embodiments, the mounting structure 20 includes multiple fixing posts 222, each fixed to the supporting rib 221 and to the peripheral edge of the fan 30. The multiple fixing posts 222 and the supporting rib 221 are connected to form a whole, improving the structural strength of the supporting rib 221 and the fixing posts 222. The multiple fixing posts 222 support the fan 30 and are fixedly connected to it. The multiple fixing posts 222 form a fixing surface or fixing line to improve the stability of the fan 30 installed within the protective box 10.

[0077] In some embodiments, the supporting ribs 221 and the plurality of fixed columns 222 are integrally formed, and the integrally formed structure ensures that there is no physical interruption between the supporting ribs 221 and the plurality of fixed columns 222, thereby improving the structural strength between the supporting ribs 221 and the plurality of fixed columns 222.

[0078] Please see Figure 11 and Figure 12 In some embodiments, the mounting structure 20 includes a plurality of second fasteners 25, each of which passes through the fan 30 and a fixing post 222. For example, it may be a screw or a bolt to enable the fan 30 to be disassembled and assembled, so as to facilitate the maintenance of the fan 30.

[0079] Please see Figure 11 and Figure 12 In some embodiments, the mounting structure 20 includes a plurality of connecting ribs 23, at least some of which connect to the supporting ribs 221 and the inner wall of the protective box 10. The plurality of connecting ribs are spaced apart along the circumference of the fan. By providing a plurality of connecting ribs 23, the structural strength between the protective box 10 and the supporting ribs 221 can be increased, and the structural stability of the supporting ribs 221 within the protective box 10 can be improved.

[0080] Among them, the connecting rib 23 can be connected to the inner wall of the protective box 10 away from the heat sink 203 and connected to the supporting rib 221 to increase the structural strength between the protective box 10 and the supporting rib 221.

[0081] In some embodiments, the connecting rib 23, the inner wall of the protective box 10, and the supporting rib 221 are integrally formed. The integrally formed structure ensures that there is no physical interruption between the connecting rib 23, the inner wall of the protective box 10, and the supporting rib 221, thereby improving the structural strength between the connecting rib 23, the inner wall of the protective box 10, and the supporting rib 221.

[0082] In some embodiments, the connecting rib 23 protrudes from the supporting rib 221 toward the communicating opening 120 so that the connecting rib 23 and the fan 30 are matched in a limiting manner, thereby quickly positioning the position of the fan 30 and improving the assembly efficiency of the fan 30 to the supporting rib 221.

[0083] In some embodiments, a support rib 221 and a plurality of fixed columns 222 form a support member 22. Both the support member 22 and the fan 30 are provided with a plurality of supports. The plurality of support members 22 and the plurality of fans 30 are connected one-to-one. Some of the connecting ribs 23 in the plurality of connecting ribs 23 are connected to the support ribs 221 of two adjacent support members 22 to improve the structural strength of the plurality of support members 22.

The flip cover 2020 is provided with connecting holes. The protective box 10 and the flip cover 2020 are fixedly connected by a third fastener 40 passing through the fastening holes and the connecting holes. For example, the third fastener 40 is a screw or bolt, so that a fixing line is formed by the third fastener 40 and the connecting post 204, thereby improving the fixed stability of the protective box 10 installed on the flip cover 2020.

[0086] Please see Figure 2 and Figure 3In some embodiments, the fixing hole 130 includes a first hole 131 and a second hole 132, which are connected. The diameter of the first hole 131 is larger than that of the second hole 132. The connecting post 204 enters the second hole 132 through the first hole 131, and the wall of the second hole 132 is press-fitted with the connecting post 204. Because the diameter of the first hole 131 is larger, it is convenient for the connecting post 204 to enter, thereby achieving rapid positioning of the connecting post 204 and the protective box 10 and improving the assembly efficiency of the protective box 10. The connecting post 204 enters the second hole 132 through the first hole 131, and the wall of the second hole 132 is press-fitted with the connecting post 204, thereby achieving a fixed connection between the protective box 10 and the flip cover 2020. By providing a fixing hole 130 in the protective box 10, a connecting post 204 is fixedly connected to the flip cover 2020. The connecting post 204 can pass through the fixing hole 130 to facilitate the installation and positioning between the protective box 10 and the flip cover 2020, so as to achieve quick installation of the protective box 10 and the flip cover 2020.

[0087] In some embodiments, a plurality of fixing holes 130 and a plurality of connecting posts 204 are provided, and the plurality of fixing holes 130 and the plurality of connecting posts 204 are connected in a one-to-one correspondence; the plurality of fixing holes 130 are distributed in an array so that the plurality of fixing holes 130 and the plurality of connecting posts 204 form a fixing surface, thereby improving the connection stability between the protective box 10 and the flip cover 2020.
