[0043] Among them, the cover body 10 moves along the direction of the first mounting structure 12 toward the second mounting structure 13, so that the first connecting member 22 is engaged with the first mounting structure 12 and the second connecting member 23 is engaged with the second mounting structure 13, so as to connect the cover body 10 to the box body 20; that is, the electrical control box structure in this embodiment realizes the assembly between the cover body 10 and the box body 20 by setting the first mounting structure 12 and the first connecting structure and the engagement and the second mounting structure 13 and the second connecting structure, so as to reduce the use of screws, avoid the risk of failure caused by the use of screws for assembly, and thereby improve assembly efficiency and reliability.

[0044] When the cover 10 and the shell need to be disassembled, the cover 10 can be moved along the second mounting structure 13 toward the first mounting structure 12 to separate the cover 10 and the shell, making disassembly convenient.

[0045] In some embodiments, the box body 20 has a bottom plate 21 and a first side plate 24, a second side plate 25, a third side plate 26 and a fourth side plate 27 that are adjacent to each other in sequence and arranged around the bottom plate 21; the first side plate 24 is opposite to the third side plate 26, and the second side plate 25 is opposite to the fourth side plate 27; wherein, the first mounting structure 12 includes a card slot 121; the first connecting member 22 includes a card block, which is located at one end of the first side plate 24 away from the bottom plate 21; the card block extends out of the box body 20 along the second mounting structure 13 toward the first mounting structure 12, and is passed through the card slot 121 to fix the cover body 10; that is, the card block and the card slot 121 in this embodiment form a tongue-type lock limit, which facilitates quick assembly between the cover body 10 and the box body 20.

[0046] Please also refer to Figure 4 and Figure 5 In some embodiments, a notch 131 is provided in the second mounting structure 13, and a slot 132 is formed at the bottom of the notch 131; the second connecting member 23 includes a cylindrical buckle, which is located at the end of the third side plate 26 away from the bottom plate 21, and the cylindrical buckle is used to engage with the slot 132 to fix the cover body 10; in this embodiment, a card block and a cylindrical buckle are respectively provided on the two opposite side plates of the box body 20. During assembly, the cover body 10 is moved along the first mounting structure 12 toward the second mounting structure 13, so that the card slot 121 engages with the card block and the cylindrical buckle engages with the slot 132, so as to fix the opposite sides of the cover body 10 to the box body 20, thereby realizing the assembly and fixation between the cover body 10 and the box body 20.

[0047] As an embodiment, the slot 132 in this embodiment may be a U-shaped slot.

[0048] Please continue reading Figure 3 In some embodiments, the cylindrical buckle includes a cylindrical body 231 and a limit platform 232; the limit platform 232 is located at the end of the cylindrical body 231 and is fixedly connected to the cylindrical body 231; the limit platform 232 is used to limit the relative displacement between the slot 132 and the cylindrical body 231 when the cylindrical body 231 is snapped into the slot 132, so that the connection between the cover body 10 and the box body 20 is more stable.

[0049] As an embodiment, a sleeve 233 is further provided on the periphery of the cylindrical body 231, and the sleeve 233 is spaced a certain distance from the limit platform 232 to expose the cylindrical body 231, so that the cylindrical buckle cooperates with the slot 132 to form a throat-type locking structure, so as to further improve the stability between the cover body 10 and the box body 20.

[0050] Please also refer to Figure 6 and Figure 7In some embodiments, a first wire fixing structure 30 is provided in the box body 20 near the third side panel 26 and extending along the first mounting structure 12 toward the second mounting structure 13; a wire outlet groove 261 is provided on both sides of the columnar buckle in the third side panel 26; wherein the number of the wire outlet grooves 261 can be two, and the columnar buckle is located between the two wire outlet grooves 261, and the first wire fixing structure 30 corresponding to each wire outlet groove 261 is located in the wire extension direction, thereby avoiding bending of the wires led out through the wire outlet groove 261, so as to improve the reliability of the electric control box structure; at the same time, the first wire fixing structure 30 is used to limit the wires led out through the wire outlet groove 261, which can ensure the orderliness of the wires in the electric control box structure and avoid damage to the wire routing.

[0051] In some embodiments, the first wire fixing structure 30 includes a wire fixing portion 31 having the same number as the wire outlet slots 261; each wire fixing portion 31 includes a set of hooks 32 arranged along the same direction; for example, two wire fixing portions 31 are arranged parallel to each other along the wire outlet direction, and the wire outlet direction is as follows: Figure 7 As shown by arrow A in the figure, the wires in the electrical control box structure of this embodiment, after exiting through the wire outlet slots 261, are inserted into the corresponding wire securing portion 31 of each wire outlet slot 261 and then led out to establish an electrical connection with the outside. Each wire securing portion 31 is provided with two hooks 32, which can further restrict the wires and improve the stability of the wire routing.

[0052] As an example, each hook 32 in this embodiment is G-shaped; each hook 32 is also provided with a protrusion. The protrusion in each hook 32 increases the contact friction between the wire and the hook 32, thereby preventing equipment malfunctions caused by wire pulling. The size of the retaining opening of the G-shaped hook 32 is slightly smaller than the size of the wire, allowing for easier insertion of different wires into the hook 32 and improving reliability.

[0053] As an embodiment, the wire outlet groove 261 may be a U-shaped groove.

[0054] In some embodiments, a wire entry groove 251 is opened in the second side plate 25 ; a second wire fixing structure 40 having the same number as the wire entry groove 251 is provided in the second side plate 25 near the wire entry groove 251 , and the second wire fixing structure 40 is used to limit the wire body introduced into the wire entry groove 251 .

A wire entry groove 251 and a second wire fixing structure 40 adapted to the wire entry groove 251 are provided on the second side plate 25. The wire entry direction is as follows: Figure 7As shown by arrow B in FIG. Similarly, in this embodiment, the number of wire entry slots 251 can be two, and the corresponding number of second wire securing structures 40 can also be two. In this embodiment, the second wire securing structure 40 is provided at the location of the wire entry slot 251 to clamp the wires introduced into the electrical control box structure, thereby preventing the wires from loosening.

[0056] In some embodiments, the second wire fixing structure 40 includes a first wire clamping assembly 41 and a second wire clamping assembly 42. The first wire clamping assembly 41 includes a first support portion 411 and a first wire clamping portion 412. The first support portion 411 is used to be fixed to the second side plate 25 to support the first wire clamping portion 412 and the second side plate 25 to be spaced apart by a preset distance. The second wire clamping assembly 42 includes a second support portion 421 and a second wire clamping portion 422. The second support portion 421 is used to be fixed to the second side plate 25 to support the second wire clamping portion 422 and the second side plate 25 to be spaced apart by a preset distance (such as Figure 7 h); In this embodiment, the first wire clamping portion 412 and the second wire clamping portion 422 are spaced apart from the second side plate 25, and are connected to the second side plate 25 through the corresponding support portion, so that there is a certain amount of movable margin between the first wire clamping portion 412 and the second wire clamping portion 422 and the second side plate 25, which is beneficial for clamping the wire while improving the reliability of the component.

[0057] Among them, the first wire clamping portion 412 and the second wire clamping portion 422 are symmetrically arranged at intervals to form a wire clamping opening 43; the symmetry axis between the first wire clamping portion 412 and the second wire clamping portion 422 is perpendicular to the thickness direction of the second side plate 25; in this embodiment, the first wire clamping portion 412 and the second wire clamping portion 422 are symmetrically arranged at intervals to form a wire clamping opening 43, and the wire clamping opening 43 is directly opposite to the corresponding wire entry groove 251, so as to prevent the wire body from bending and being easily damaged.

[0058] As an embodiment, the first wire clamping portion 412 and the second wire clamping portion 422 in this embodiment are similar to an S shape, and the first wire clamping portion 412 and the second wire clamping portion 422 located at the wire clamping opening 43 are in a downward pressing form, which is convenient for clamping the wire body and also ensures that the wire body is not easy to loosen.

[0059] In some embodiments, a limiting member 44 is provided on both the first support portion 411 and the second support portion 421, and a limiting groove is formed between the limiting member 44 and the second side panel 25; the cover body 10 also includes a third mounting structure 14, which is located between the first mounting structure 12 and the second mounting structure 13; when the cover body 10 is moved and assembled along the first mounting structure 12 toward the second mounting structure 13, the third mounting structure 14 at this time moves along the limiting groove, and at this time the first supporting structure and the second supporting structure can form a supporting role for the third mounting structure 14, and the limiting groove formed by the limiting member 44 can play the role of installation limiting guide, which is beneficial to improve the assembly efficiency between the cover body 10 and the box body 20.

[0060] In some embodiments, a reinforcing rib 15 is provided on the side of the cover plate 11 away from the box body 20, and the reinforcing rib 15 is located near the first mounting structure 12. The reinforcing rib 15 is in an "eight" shape, and a through-slot 16 is provided in the cover plate 11 at the top of the "eight"-shaped reinforcing rib 15. When the box body 20 and the cover body 10 are mounted and fixed, the locking block in the box body 20 can be seen through the through-slot 16. In other words, the provision of the through-slot 16 in this embodiment allows the locking block to be visualized, making it easier to check whether the box body 20 and the cover body 10 are properly assembled, thereby improving the reliability of the electric control box body 20.
