[0039] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in
[0040] a box body 100, the box body 100 defines a receiving cavity C for arranging electrical components; the box body 100 is provided with a wire passing port 111 communicating with the receiving cavity C for leading out the wire harness of the electrical components from the receiving cavity C; and
[0041] a wire fixing structure 120, the wire fixing structure 120 is arranged on the box body 100, and the wire fixing structure 120 is arranged beside the wire passing port 111. The wire fixing structure 120 has a wire fixing hole S, and the projection of the wire fixing hole S in the wire outlet direction of the wire harness is located within the wire passing port 111.
[0042] In the technical solution of the embodiment of the present application, a wire passing opening 111 is provided on the box body 100 to lead the wiring harness of the electrical components in the accommodating cavity C of the box body 100 out of the box body 100; a wire fixing structure 120 is provided on the box body 100 and is arranged next to the wire passing opening 111; a wire fixing hole S of the wire fixing structure 120 is used to accommodate the wiring harness led out of the box body 100; since the projection of the wire fixing hole S in the wire outlet direction of the wiring harness is located in the wire passing opening 111, after multiple wiring harnesses are led out from the wire passing opening 111, the wire fixing hole S can compress the space between the wiring harnesses so that the multiple wiring harnesses are gathered by the wire fixing hole S after passing through the wire passing opening 111, so that the multiple wiring harnesses are reliably and firmly secured.
[0043] In the embodiment, the projection of the wire fixing hole S in the wire outlet direction of the wire harness is located within the wire passing opening 111, which can be understood as the hole area of the wire fixing hole S is smaller than the opening area of the wire passing opening 111; for example, the wire passing opening 111 is circular, and the projection of the wire fixing hole S is located within the circle.
[0044] In an embodiment, the wire fixing structure 120 may be integrally formed on the box body 100 , or may be fixed to the box body 100 by welding, threaded connection, or the like.
[0045] Optionally, the wire-passing opening 111 has a first opening O1 located on the end face of the box body 100, and the wire-passing opening 111 is formed with a first chamfered structure 111a at the first opening O1; the wire-fixing structure 120 moves away from the first chamfered structure 111a toward the inner side of the wire-passing opening 111 in the vertical direction to form a wire-passing space Z. In an embodiment, a plurality of wire harnesses are inserted into the wire-passing opening 111 through the first opening O1, and the first chamfered structure 111a is provided to guide the wire harnesses. In an embodiment, the wire-fixing structure 120 moves away from the first chamfered structure 111a toward the inner side of the wire-passing opening 111 in the vertical direction to form a wire-passing space Z; the wire-passing space Z facilitates guiding the wire harnesses that deviate from the wire-fixing structure 120 into the wire-fixing hole S.
[0046] As an optional implementation of the above embodiment, the wire fixing hole S has a second opening O2, and a second chamfered structure 1421 arranged toward the inside of the wire fixing space is provided at the second opening O2, and the second chamfered structure 1421 and the first chamfered structure 111a are close to each other. In the embodiment, the wire harness passing through the wire space Z is guided by the second chamfered structure 1421 and inserted into the wire fixing hole S through the second opening O2, thereby achieving the clamping of the wire harness.
[0047] When threading the wire harness, along the direction close to the first chamfer structure 111a, the wire harness is successively snapped into the wire passing port 111 and the wire fixing hole S. When the wire harness closest to the first chamfer structure 111a is snapped into the wire passing port 111, it passes through the wire passing space Z, and then is snapped into the wire fixing hole S under the guidance of the second chamfer structure 1421, realizing the clamping of the wire harness. Alternatively, when threading the wire harness, first pre-gather and snap the wire harness into the wire passing port 111, and then snap the wire harness into the wire fixing hole S. At this time, the wire harness located outside the wire fixing structure 120 will pass through the wire passing space Z and then be snapped into the wire fixing hole S under the guidance of the second chamfer structure 1421.
[0048] As an alternative implementation of the above embodiment, the wire passing port 111 has a first opening O1 on the end face of the box body 100, and the wire fixing hole S has a second opening O2 formed on the periphery of the wire fixing structure 120. The orientations of the first opening O1 and the second opening O2 are opposite to each other. As Figure 2 shown, the wire harness can be snapped into the wire passing port 111 and the wire fixing hole S from the first opening O1 and the second opening O2 respectively. Setting the two openings to face in opposite directions can prevent the wire harness from being unconstrained due to an accident; even if the wire harness accidentally slips out of the wire passing port 111 or the wire fixing hole S, it can still be constrained by the other one, improving the reliability of the wire harness being fixed.
[0049] As an alternative implementation of the above embodiment, the wire fixing structure 120 includes a fixing section 123 and a wire fixing section 124. The wire fixing section 124 has the wire fixing hole S; the wire fixing section 124 is connected to the fixing section 123; one side of the fixing section 123 away from the wire fixing section 124 is connected to the box body 100; wherein, the second chamfer structure 1421 is provided at one end of the wire fixing section 124 away from the fixing section 123. In the embodiment, the fixing section 123 mainly functions to connect the box body 100, and the wire fixing section 124 mainly functions to fix the wire harness. In the embodiment, the wire fixing section 124 is in a U-shaped structure to form a wire fixing hole S; and the fixing section 123 is also in a U-shaped structure.
[0050] In some embodiments, the wire fixing section 124 is an elastic structure, such as a metal sheet or a plastic elastic sheet. The fixing section 123 is in a U-shaped structure, which is convenient for deforming during wire threading and restoring the deformation after wire threading to clamp the wire harness.
[0051] As an alternative implementation of the above embodiment, the wire fixing structure 120 includes a first wire fixing structure 121 and a second wire fixing structure 122. The first wire fixing structure 121 and the first wire passing port 111 are spaced apart to form a first wire passing space Z1. The second wire fixing structure 122 and the second wire passing port 111 are spaced apart to form a second wire passing space Z2. The spatial sizes of the first wire passing space Z1 and the second wire passing space Z2 are different.
[0052] For example, in combination with Figure 2 and Figure 4 As shown, the first wire fixing structure 121 and the second wire fixing structure 122 are arranged at intervals along the length direction of the box body 100, and the first wire fixing structure 121 and the first wire passing port 111 are arranged at intervals to form a first wire passing space Z1. The space sizes of the first wire passing space Z1 and the second wire passing space Z2 are different to facilitate accommodating wire harnesses of different specifications. For example, the dimensions of the first wire passing space Z1 and the second wire passing space Z2 along the length direction are different, for example, one is 4.5 mm and the other is 3.5 mm.
[0053] In the embodiment, the first wire fixing structure 121 is formed with a first wire fixing hole S1, and the second wire fixing structure 122 is formed with a second wire fixing hole S2; the wire passing port 111 includes a first wire passing port 1111 and a second wire passing port 1112. The first wire fixing hole and the first wire passing port are arranged in pairs, and the projection of the first wire fixing hole in the wire outlet direction of the wire harness is located within the first wire passing port 1111. The second wire fixing hole S2 and the second wire passing port 1112 are arranged in pairs, and the projection of the second wire fixing hole in the wire outlet direction of the wire harness is located within the second wire passing port 1112.
[0054] As an alternative implementation of the above embodiment, in combination with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the electric control box 10 further includes a box cover 200, and the box cover 200 is configured to be slidable along the box body 100 for opening or closing the accommodation cavity C. Wherein, when the box cover 200 closes the accommodation cavity C, the wire fixing structure is located outside the box cover 200. In the embodiment, as Figure 1 shown, the wire fixing structure is located outside the box cover 200, which is convenient for having a certain operating space to re - clip the escaped wire harness into the wire fixing hole after the wire harness accidentally escapes from the wire fixing hole S.
[0055] As an alternative implementation of the above embodiment, a sliding fit portion 130 is provided on the box body 100, and the box cover 200 is configured to move along the sliding fit portion 130; a limiting structure 140 is provided on the sliding fit portion 130; a positioning structure 210 is provided on the box cover 200; when the positioning structure 210 abuts against the limiting structure 140, the box cover 200 closes the accommodation cavity C. As Figure 1As shown, the sliding fit portion 130 extends along the length direction of the box body 100; the box cover 200 has a cover body and a sliding edge bent at the edge of the cover body; the sliding edge is provided with a positioning structure 210, and the positioning structure 210 cooperates with the sliding fit portion 130 to guide the movement of the box cover 200, thereby closing or opening the accommodation cavity C. A limiting structure 140 is provided on the sliding fit portion 130; when the positioning structure 210 slides to abut against the limiting structure 140, the box cover 200 reaches the position of closing the accommodation cavity C to prevent the box cover 200 from sliding excessively and unable to be effectively positioned.
[0056] In the embodiment, the first opening O1 of the wire passing port 111 is arranged on the sliding surface of the sliding fit portion 130, as Figure 2 shown. The wire passing port 111 divides the sliding fit portion 130 into multiple sections. In the embodiment, arranging the first opening O1 of the wire passing port 111 on the sliding surface of the sliding fit portion 130 facilitates the installation of the box cover 200 after the wire harness is led out of the box body 100.
[0057] In the embodiment, the limiting structure 140 protrudes from the sliding surface; when the positioning structure 210 moves along the sliding surface to the limiting structure 140, the box cover 200 reaches the position of closing the accommodation cavity C.
[0058] In some embodiments, the fixed section 123 is connected to the sliding fit portion 130, which can strengthen the sliding fit portion 130.
[0059] In the embodiment, the sliding fit portion 130 is bent and formed on the end surface of a side wall 110 of the box body 100 and extends outward from the box body 100, as Figure 2 shown.

[0061] In an embodiment, the first snap structure 220 is a snap hole, and the second snap structure 151 is a snap structure; when the positioning structure 210 slides to abut against the limiting structure 140, the snap structure snaps into the snap hole, and the two cooperate. The snap hole is provided as a through hole, facilitating that when the positioning structure 210 slides to abut against the limiting structure 140, an installer can determine whether the lid 200 is in place by observing whether the snap structure is snapped into the through snap hole. In the embodiment, reinforcing ribs are provided around the snap hole.
[0062] As an alternative implementation of the above embodiment, a first connection hole 230 is provided on one side of the lid 200 in its moving direction. A second connection hole 1521 is provided on one side of the box body 100 in the moving direction. The electronic control box 10 further includes a connecting member that connects the first connection hole 230 and the second connection hole 1521. In the embodiment, when the lid 200 closes the accommodation cavity C, the first connection hole 230 gradually approaches the second connection hole 1521 until the first connection hole 230 and the second connection hole 1521 are coaxial. At this time, the first connection hole 230 and the second connection hole 1521 are connected through the connecting member, and then the lid 200 is fixed to the box body 100.
[0063] As Figure 1 shown, the second connection hole 1521 and the second snap structure 151 are located on opposite sides in the moving direction.
