[0027] Another embodiment of this application provides an electronic control box; please refer to [link / reference needed]. Figure 1 The electrical control box includes a box body 20 and an electrical control board protective structure 10, with the electrical control board protective structure 10 disposed inside the box body 20.

[0028] Please see Figures 1 to 3 The electronic control board protection structure 10 of this application embodiment includes an electronic control component 11 and a protective shell 12.

[0029] The electronic control assembly 11 includes a mounting box 111 with a support wall 1111 and an electronic control board 112 disposed on the support wall 1111. A protective shell 12 is detachably disposed on the side of the electronic control board 112 opposite to the support wall 1111 and abuts against the electronic control board 112.

[0030] The support wall 1111 is used to support the electronic control board 112.

[0031] The protective shell 12 is detachably mounted on the electronic control board 112. That is, the protective shell 12 can be removed from the side of the electronic control board 112 away from the support wall 1111 to facilitate the maintenance or replacement of the electronic control board 112.

[0032] The protective shell 12 covers the electronic control board 112, that is, the protective shell 12 has a cavity, and at least a part of the electronic control board 112 can be located in the cavity, so that the protective shell 12 not only has the function of fixing the electronic control board 112, but also has the function of protecting the electronic control board 112 and preventing the electronic control board 112 from being damaged by other objects.

[0033] During the assembly of the electrical control box, the electrical control board 112 can be installed on the mounting box 111 by means of snap-fit ​​or fastening. Then, the protective shell 12 is placed on the electrical control board 112 and connected to the mounting box 111. Finally, the protective structure 10 of the electrical control board is installed into the box body 20 of the electrical control box.

[0034] Since the control board 112 is disposed on the support wall 1111 of the mounting box 111, and the protective shell 12 abuts against the side of the control board 112 away from the support wall 1111, the control board 112 is essentially sandwiched between the support wall 1111 and the protective shell 12. The mounting box 111 and the protective shell 12 can fix the opposite sides of the control board 112 respectively, thereby effectively preventing the control board 112 from loosening. Therefore, the control board protection structure 10 of this embodiment can provide good protection for the control board 112.

[0035] In addition, the electronic control assembly 11 also includes a plurality of electrical components disposed on the electronic control board 112. The type of electrical components is not limited. For example, the electrical components include, but are not limited to, capacitors, transformers, and relays. At least some of the electrical components may be located within the protective housing 12.

[0036] In other words, when the protective shell 12 is placed over the electronic control board 112, at least some of the electrical components on the electronic control board 112 are located inside the cavity of the protective shell 12. Thus, the electrical components located inside the protective shell 12 can be protected by the protective shell 12 to prevent them from being damaged by other objects during transportation.

[0037] In one embodiment, please refer to Figure 1 The box body 20 may include a box body 21 and a box cover (not shown). The box body 21 has a receiving cavity 21a and an installation port 21b communicating with the receiving cavity 21a. The electronic control board protective structure 10 is disposed in the receiving cavity 21a, and the protective shell 12 is located between the electronic control board 112 and the installation port 21b. The box cover is disposed at the installation port 21b and abuts against the protective shell 12.

[0038] In other words, when the protective structure 10 of the control board is installed inside the box 20, the side of the protective shell 12 away from the control board 112 abuts against the box cover. That is, the box cover applies a certain squeezing force to the protective shell 12, so that the protective shell 12 can be pressed tightly against the control board 112, thereby better preventing the control board 112 from loosening.

[0039] In one embodiment, please refer to Figures 1 to 3 The protective housing 12 may include a main body 121 and an abutment portion 122 disposed on one side of the main body 121. The main body 121 covers the electronic control board 112, and the abutment portion 122 abuts against the electronic control board 112. At least one of the main body 121 and the abutment portion 122 is detachably connected to the mounting box 111.

[0040] The abutting part 122 is used to abut against the electronic control board 112 to fix the electronic control board 112.

[0041] The main body 121 covers the electronic control board 112 and can protect the electronic control board 112. The main body 121 can be spaced apart from the electronic control board 112, that is, the main body 121 does not contact the electronic control board 112. In another embodiment, the main body 121 can also abut against the electronic control board 112 to further fix the electronic control board 112.

[0042] At least one of the main body 121 and the abutment part 122 is detachably connected to the mounting box 111, which allows the abutment part 122 to remain in contact with the electronic control board 112, thereby enhancing the installation stability of the electronic control board 112. For example, Figures 1 to 3 In the illustrated electronic control board protective structure 10, both the main body 121 and the abutment part 122 are detachably connected to the mounting box 111 to ensure the connection stability between the protective shell 12 and the mounting box 111. In another embodiment, the main body 121 may be connected to the mounting box 111 while the abutment part 122 is not connected to the mounting box 111, or the abutment part 122 may be connected to the mounting box 111 while the main body 121 is not connected to the mounting box 111.

[0043] For example, please refer to Figure 2 and Figure 3 At least one of the main body 121 and the abutment portion 122 can be snapped into the mounting box 111. This snap-fit ​​connection allows for quick assembly and disassembly between the protective shell 12 and the mounting box 111, improving production efficiency. In another embodiment, at least one of the main body 121 and the abutment portion 122 can also be connected to the mounting box 111 via other detachable connection methods such as a fastening connection.

[0044] Please continue reading. Figure 2 and Figure 3 The main body 121 may be provided with one of a first snap-fit ​​seat 1211 and a first elastic snap-fit ​​foot 1112, and the mounting box 111 is provided with the other of the first snap-fit ​​seat 1211 and the first elastic snap-fit ​​foot 1112. The first snap-fit ​​seat 1211 has a first snap-fit ​​opening, and the first elastic snap-fit ​​foot 1112 passes through the first snap-fit ​​opening and snaps with the end face of the first snap-fit ​​seat 1211 located on the periphery of the first snap-fit ​​opening.

[0045] In other words, the first elastic locking foot 1112 is inserted through the first locking opening and engaged with the end face of the first locking seat located on the periphery of the first locking opening, thereby realizing the detachable connection between the main body 121 and the mounting box 111. This connection method enables the rapid assembly of the main body 121 and the mounting box 111, improving production efficiency.

[0046] It should be noted that since the main body 121 and the mounting box 111 are connected by the first snap-fit ​​seat 1211 and the first elastic snap-fit ​​foot 1112, the mounting box 111 can provide a certain support for the main body 121 through the first snap-fit ​​seat 1211 and the first elastic snap-fit ​​foot 1112.

[0047] For example, please refer to Figure 2 and Figure 3 , Figure 2 and Figure 3 The main body 121 is provided with a first latching seat 1211, and the mounting box 111 is provided with a first elastic latching foot 1112. The first latching seat 1211 is located on the periphery of the main body 121, and the first elastic latching foot 1112 is located on the periphery of the mounting box 111. When the control board protective structure 10 is located inside the box 20, and the protective shell 12 is located between the control board 112 and the mounting opening 21b, the first elastic latching foot 1112 located in the mounting box 111 can easily release the first elastic latching foot 1112 from the first latching seat 1211.

[0048] In another embodiment, the main body 121 may be provided with a first elastic locking foot 1112, and the mounting box 111 may be provided with a first locking seat 1211.

[0049] Please see Figures 1 to 3 The abutment portion 122 may be provided with one of a second snap-fit ​​seat 1221 and a second elastic snap-fit ​​foot 1113, and the mounting box 111 is provided with the other of the second snap-fit ​​seat 1221 and the second elastic snap-fit ​​foot 1113. The second snap-fit ​​seat 1221 has a second snap-fit ​​opening 1221a, and the second elastic snap-fit ​​foot 1113 passes through the second snap-fit ​​opening 1221a and snaps with the end face of the second snap-fit ​​seat 1221 located on the periphery of the second snap-fit ​​opening 1221a.

[0050] In other words, the second elastic locking foot 1113 is inserted through the second locking opening 1221a and engaged with the end face of the second locking seat located on the periphery of the second locking opening 1221a, thereby realizing the detachable connection between the abutment part 122 and the mounting box 111.

[0051] When the abutting part 122 abuts against the electronic control board 112, the abutting part 122 applies a certain pressure to the electronic control board 112. At the same time, the abutting part 122 is engaged with the mounting box 111 through the second retainer and the second elastic retaining foot 1113. This ensures that the abutting part 122 is always in contact with the electronic control board 112, thereby preventing the electronic control board 112 from being dislodged when the electronic control board protective structure 10 is subjected to external impact. In some embodiments, the abutting part 122 can also increase the pressure applied to the electronic control board 112 by connecting to the mounting box 111, further increasing the installation stability of the electronic control board 112.

[0052] In one embodiment, please refer to Figures 1 to 3 The protective shell 12 may include a main body 121 and a pressure plate 123 located on the side of the main body 121 away from the electronic control board 112. The pressure plate 123 applies a compressive force to the protective shell 12 by generating elastic deformation under the action of external force.

[0053] Please see Figure 1 When the electrical control board protective structure 10 is installed inside the box body 21, the pressure plate 123 can face the mounting opening 21b of the box body 21. When the box cover is installed at the mounting opening 21b, the pressure plate 123 is located between the box cover and the main body 121 and abuts against the box cover. This means that the external force acting on the pressure plate 123 can be the squeezing force applied by the box cover to the pressure plate 123.

[0054] For example, please refer to Figure 2 The pressure plate 123 may include a connecting section 1231 and a supporting section 1232. The connecting section 1231 is connected to the main body 121 and the supporting section 1232 respectively, so that a deformation space is formed between the supporting section 1232 and the main body 121.

[0055] The support section 1232 is used to withstand external forces, that is, external forces are applied to the support section 1232.

[0056] The connecting segment 1231 is used to connect the main body 121 and the support segment 1232. A deformation space is formed between the support segment 1232 and the main body 121. That is, the connecting segment 1231 extends in a direction away from the main body 121 and forms a certain angle with the main body 121. This angle is either acute or obtuse, so that when the pressure plate 123 is subjected to external force and undergoes elastic deformation, the support segment 1232 will displace in a direction closer to the main body 121.

[0057] An external force is applied to the pressure plate 123, causing the pressure plate 123 to transmit the external force to the protective shell 12 through its own elastic deformation, thereby further increasing the pressure exerted by the protective shell 12 on the electronic control board 112.

[0058] In addition, since the pressure plate 123 will undergo elastic deformation when subjected to external force, when the electronic control board protective structure 10 is subjected to other impacts or vibrations, the pressure plate 123 can absorb and disperse the impact force or vibration, reducing damage to the electronic control board 112.

[0059] In one embodiment, please refer to Figures 1 to 3 The protective shell 12 may have a top wall 124 facing the electronic control board 112, and a portion of the structure of the top wall 124 protrudes from the side close to the electronic control board 112 to the side away from the electronic control board 112 to form a reinforcing rib 1241.

[0060] In other words, a portion of the top wall 124 near the control board 112 is recessed, while the corresponding portion on the side away from the control board 112 is protruding.

[0061] The reinforcing rib 1241 can enhance the structural strength of the protective shell 12 and reduce the possibility of deformation of the top wall 124 due to external forces.

[0062] Furthermore, the capacitor can be located between the control board 112 and the reinforcing rib 1241. That is, the capacitor is placed inside the protective shell 12, and the side of the capacitor away from the control board 112 faces the reinforcing rib 1241.

[0063] Because the capacitor is relatively large, placing it between the control board 112 and the reinforcing rib 1241 allows for full utilization of the space between them. This helps to reduce the size of the protective shell 12.

[0064] In one embodiment, please refer to Figures 1 to 3 The protective shell 12 may also be provided with heat dissipation holes 12a. The area of ​​the electronic control board 112 covered by the protective shell 12 can be cooled through the heat dissipation holes 12a.

[0065] Figures 1 to 3 The protective shell 12 has multiple heat dissipation holes 12a on its periphery and on the side facing the electronic control board 112. In other embodiments, the location of the heat dissipation holes 12a on the protective shell 12 can be adjusted as needed.

[0066] In one embodiment, please refer to Figure 1 and Figure 3 The electronic control assembly 11 may also include a grounding component located inside the protective housing 12. The grounding component is connected to the electronic control board 112 and the mounting box 111 respectively. The protective housing 12 has a wiring port 12b corresponding to the grounding component.

[0067] Grounding components are used to ground the electrical control box to prevent electric shock accidents and also to reduce electromagnetic interference.

[0068] Terminal 12b is used for passing the grounding wire. That is, the grounding component is connected to the grounding wire to achieve grounding.

[0069] The type of grounding component is not limited. For example, the grounding component can be a grounding bolt, grounding screw, etc.
