[0053] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0054] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" are generally defined with respect to the directions of the drawings. A first direction is angled relative to the direction in which the first wiring harness extends, a second direction is parallel to the direction in which the second wiring harness extends, and a third direction is angled relative to the direction in which the third wiring harness extends. "Inner" and "outer" refer to the inside and outside of the relevant component. Furthermore, the terms "first" and "second," etc., are used solely for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0055] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0056] In electrical appliances, the electric control box is an important structure involving circuit connection and circuit control, which involves a lot of wiring harness routing design. However, the electric control box cannot take up too much space. The size of the electric control box is often not large, so it is necessary to realize reasonable wiring of the wire harness in the limited space.

[0057] In the related art, the wiring structure of the wiring harness fixing device of the main control board bracket of the electric control box occupies a large space and is often an identical structure. However, the internal space of the electric control box is limited, which will affect the layout between the main control board bracket of the electric control box and adjacent components, resulting in the space utilization inside the electric control box being affected, and at the same time affecting the layout of the wiring harness.

[0058] For this reason, Figures 1-10 As shown, one aspect of the present disclosure provides a wire harness fixing device, which is applied to a main control board bracket of an electric control box, and includes a first clamping member 2 and a second clamping member 3.

[0059] The first clamping member 2 has a first receiving portion 21 . An end of the first receiving portion 21 away from the first clamping member 2 has a first inclined surface 22 .

[0060] The second clamping member 3 has a second receiving portion 31 . An end of the second receiving portion 31 away from the second clamping member 3 has a second inclined surface 32 .

[0061] The first receiving portion 21 and the second receiving portion 31 are both used to support the first wire harness, and the inclination of the first inclined surface 22 is greater than the inclination of the second inclined surface 32 .

[0062] In the above technical solution, by setting the inclination of the first inclined surface 22 and the inclination of the second inclined surface 32 to be different, the structural dimensions of the first receiving portion 21 and the second receiving portion 31 are different, thereby being able to adapt to the components close to the main control board bracket of the electric control box, and the first clip 2 or the second clip 3 can be selected according to the structure of the adjacent components to be set adjacent to the component, which can reduce the space occupied by the wire harness fixing device and the component, and can be used in a narrower space, thereby making the space layout in the electric control box reasonable and compact, and improving the space utilization rate in the electric control box.

[0063] To enhance the position-limiting and supporting effect on the wiring harness, optionally, in one embodiment of the present disclosure, in a first direction, the first clamping member 2 and the second clamping member 3 are disposed opposite each other, the first receiving portion 21 and the second receiving portion 31 are both located between the first clamping member 2 and the second clamping member 3, and the first receiving portion 21 and the second receiving portion 31 jointly support the first wiring harness. The first direction is disposed at an angle to the extension direction of the first wiring harness.

[0064] The space between the first connector 2 and the second connector 3 is used to place the first wiring harness for routing, while the first receiving portion 21 and the second receiving portion 31 can each support a portion of the first wiring harness, thereby jointly supporting the first wiring harness. It is understood that when the first wiring harness is placed on the first receiving portion 21 and the second receiving portion 31, the first wiring harness is supported, and the first connector 2 and the second connector 3 can simultaneously provide a certain clamping and fixing effect to secure the first wiring harness. In some examples, the first direction is perpendicular to the extension direction of the first wiring harness.

[0065] Optionally, in one embodiment of the present disclosure, there are multiple first clips 2 and second clips 3, and the first clips 2 correspond to the second clips 3 one by one. The multiple first clips 2 and second clips 3 are spaced apart along the second direction, and the second direction is set as the extension of the first wiring harness. With this arrangement, the multiple first clips 2 and second clips 3 can support multiple positions of the extended first wiring harness.

[0066] In order to accommodate more first wire harnesses and better constrain the first wire harnesses, in an embodiment of the present disclosure, the first inclined surface 22 and the second inclined surface 32 are both inclined downward, and the first inclined surface 22 and the second inclined surface 32 are oppositely arranged, and the space between the first inclined surface 22 and the second inclined surface 32 and the gap 13 together form the first wire routing groove 11 for accommodating the first wire harness.

[0067] The first inclined surface 22 and the second inclined surface 32 are inclined downward, which can form a downward recessed storage space, so that more first wire harnesses can be placed, and the first inclined surface 22 and the second inclined surface 32 are oppositely arranged, which can generate an acting force on the first wire harnesses between them, thereby achieving clamping and constraining the first wire harnesses.

[0068] The first inclined surface 22 and the second inclined surface 32 are oppositely arranged, and the space between the first inclined surface 22 and the second inclined surface 32 and the gap 13 together form the first wire routing groove 11 for accommodating the first wire harnesses, which can accommodate more first wire harnesses, and the inclination of the first inclined surface 22 and the second inclined surface 32 is different, which does not occupy too much space, so that more first wire harnesses can be placed while saving space, which can realize the wire layout in a narrow space, and can realize safe and beautiful wire layout.

[0069] In another embodiment of the present disclosure, the first inclined surface 22 and the second inclined surface 32 are both inclined downward, and in the first direction, the end of the first receiving portion 21 away from the first clamping member 2 and the end of the second receiving portion 31 away from the second clamping member 3 are in contact with each other, the first inclined surface 22 and the second inclined surface 32 are oppositely arranged, and the space between the first inclined surface 22 and the second inclined surface 32 forms the first wire routing groove 11 for accommodating the first wire harness.

[0070] In an embodiment of the present disclosure, the width of the gap 13 in the first direction is 4.5mm-4.7mm, that is, the width shown in D1 in FIG. 4. By such arrangement, the width of the first wire routing groove 11 can be increased as much as possible, and more first wire harnesses can be placed, and the first wire harnesses will not fall off from the gap 13. It should be noted that the width of the gap 13 can be adjusted according to specific needs. Figure 3

[0071] In another embodiment of the present disclosure, the first receiving portion 21 and the second receiving portion 31 support different first wire harnesses, and the first clamping member 2 and the second clamping member 3 can be arranged at appropriate positions as needed.

[0072] ​In order to further reduce the size of the first receiving portion 21 and reduce the space occupied, optionally, in one embodiment of the present disclosure, the first receiving portion 21 is constructed as a boss formed on the first clamping member 2, the boss extends along the first direction, and the side of the boss away from the first clamping member 2 is set to be inclined downward from the top to form a first inclined surface 22.

[0073] The boss is integrally formed with the first clip 2, and the boss is perpendicular to the first clip 2. In the first direction, the boss extends toward the second receiving portion 31. The boss cooperates with the second receiving portion 31 to support the first wiring harness. The design of the boss allows the side of the boss away from the first clip 2 to tilt downward from the top, thereby forming a first inclined surface 22. The large inclination angle allows the length of the boss in the first direction to be set smaller. As the length of the boss decreases, the width of the gap 13 is fixed, and the distance between the first clip 2 and the second clip 3 can be reduced, thereby greatly reducing the space occupied by the first clip 2 and the second clip 3 in the first direction.

[0074] Optionally, in one embodiment of the present disclosure, in the first direction, the length of the boss is 5.3 mm to 5.5 mm. Figure 4 By setting it in this way, the length of the boss can be controlled and the space occupied can be reduced. It should be noted that the specific length of the boss can be set according to actual needs.

[0075] In order to maintain the restraining effect on the first wiring harness, optionally, in one embodiment of the present disclosure, the second receiving portion 31 is constructed as a hook formed on the second clamping member 3, the hook extends along the first direction, and the top of the hook is set to bend obliquely downward to form a second inclined surface 32.

[0076] Among them, the cooperation between the hook and the boss can maintain the restraining effect on the first wire harness while reducing the space occupied. It can be understood that the bending setting of the hook can have a certain elasticity, which can better produce a pushing effect on the first wire harness, and facilitate the later wire clamping and fixation, thereby being able to cooperate with the first inclined surface 22 of the boss to better achieve the restraining effect on the first wire harness. If the first receiving portion 21 is also set as a boss, the gap 13 between the first receiving portion 21 and the second receiving portion 31 will be too large, and the height of the boss will be too early, which will affect the later mold manufacturing, and is also not conducive to restraining the first wire harness. In some examples, in the first direction, the width of the end of the hook away from the end of the second clamping member 3 is 1mm-1.2mm. That is Figure 4 The distance shown in D5.

[0077] Optionally, in one embodiment of the present disclosure, the wire harness securing device further comprises a first base 1, the first base 1 being connected to the main control board bracket of the electric control box, and at least one of the first clamping member 2 and the second clamping member 3 being formed on the first base 1. The first base 1 can be extended outward, thereby facilitating the routing of the first wire harness without affecting the placement of related components within the main control board bracket of the electric control box, and the first base 1 can provide support for at least one of the first clamping member 2 and the second clamping member 3.

[0078] The first base 1 can be integrally formed with the outer sidewall of the main control board bracket of the electric control box. In some examples, the second clip 3 can be integrally formed with the first base 1, and the first clip 2 can be connected to the sidewall of the main control board bracket of the electric control box. In other examples, both the first clip 2 and the second clip 3 can be integrally formed with the first base 1.

[0079] Optionally, in one embodiment of the present disclosure, the first clamping member 2 and the second clamping member 3 are both located above the first base 1, and a second wiring groove 12 is formed on the first base 1. The second wiring groove 12 is located between the first clamping member 2 and the second clamping member 3, and below the first receiving portion 21 and the second receiving portion 31. Wiring can also be achieved through the formation of the second wiring groove 12. It is arranged above and below the first wiring groove 11 to achieve double-layer wiring, which can greatly utilize the wiring space and greatly improve the wiring safety and aesthetics.

[0080] A downwardly facing recessed groove is formed on the top of the first base 1, serving as a second wiring groove 12. A portion of the first wiring harness can be accommodated in the first wiring groove 11, and another portion can be accommodated in the second wiring groove 12. It is understood that the second wiring groove 12 is located between the first clamping member 2 and the second clamping member 3, and the first clamping member 2 and the second clamping member 3 can serve as auxiliary position limiters for the first wiring harness accommodated in the second wiring groove 12.

[0081] In some examples, in the first direction, the width of the second wiring groove 12 is 7 mm to 8 mm, that is, Figure 3 The distance shown by D3 is 12mm-14mm from the bottom of the second wiring groove 12 to the bottom surface of the first base 1. Figure 3 It should be noted that the specific values ​​of the width of the second wiring groove 12 and the straight-line distance between the groove bottom of the second wiring groove 12 and the bottom surface of the first base 1 can be set according to actual conditions.

[0082] Optionally, in one embodiment of the present disclosure, a third wire pressing portion 9 may be provided on one side of a first clamping member 2 and a second clamping member 3 .

[0083] The third wire pressing portion 9 is connected to the main control board bracket of the electric control box. A third wire pressing hook 91 is formed on the third wire pressing portion 9. The third wire pressing hook 91 cooperates with the first wiring groove 11 to fix the first wire harness.

[0084] Among them, the third wire pressing part 9 can press the first wire harness downward, and the first wire routing groove 11 can limit the side of the first wire harness. Therefore, the cooperation between the third wire pressing part 9 and the first wire routing groove 11 can realize the constraint of the first wire harness in the upper and lower directions, so that the first wire harness is arranged along the design direction.

[0085] It is understandable that the third wire pressing hook 91 has a hook groove, and the first wire harness can be positioned in the hook groove of the third wire pressing hook 91. As the third wire pressing hook 91 is hooked, downward pressure is achieved, thereby generating a restraining effect on the first wire harness.

[0086] Optionally, in one embodiment of the present disclosure, the wire harness fixing device further includes a wire harness lifting portion 4 .

[0087] The main control board bracket of the electric control box has two oppositely disposed ends. The wire harness lifting portion 4 is connected to one end of the main control board bracket of the electric control box, and the first clamping member 2 and the second clamping member 3 are located at the other end of the main control board bracket of the electric control box. The wire harness lifting portion 4 is provided with a limit slot 43 for receiving the second wire harness.

[0088] The harness lifting portion 4 can raise the height of the second harness, thereby reasonably constraining the second harness according to the wiring layout of the second harness and adapting to the height position of the second harness. By setting it in this way, the second harness can be constrained as needed to meet the diverse needs of different wiring layouts.

[0089] It is understandable that the second wiring harness is clipped into the limiting groove 43, and the second display can be constrained by the limiting groove 43. It should be noted that the wiring harness lifting portion 4 here constrains the second wiring harness, that is, the wiring harness located at one end of the main control board bracket of the electric control box, and the first clamping member 2 and the second clamping member 3 constrain the first wiring harness, that is, the wiring harness located at the other end of the main control board bracket of the electric control box. In this way, different wiring harnesses can be constrained separately to achieve a reasonable routing layout.

[0090] In order to make more reasonable use of space, optionally, in one embodiment of the present disclosure, the wire harness lifting portion 4 includes an integrally formed base 41 and a placement seat 42, the placement seat 42 is located at the top of the base 41, the limiting groove 43 is provided at the top of the placement seat 42, and the base 41 is connected to the main control board bracket of the electric control box. In the first direction, the width of the base 41 is smaller than the width of the placement seat 42, and the first direction is set at an angle to the extension direction of the second wire harness. By making the width of the base 41 in the first direction smaller than the width of the placement seat 42, the wire harness lifting portion 4 can be made to have a structure that is wide at the top and narrow at the bottom, so that some complexly designed components in the electric control box can be cleverly avoided, such as the uneven structure of the inner wall of the electric control box, or the complex components in the electric control box, and the space can be used more reasonably.

[0091] The base 41 is located below the mounting seat 42 and is used to secure the mounting seat 42. The retaining groove 43 is located at the top of the mounting seat 42 and is used to accommodate the second wiring harness. The base 41 and mounting seat 42 are wide at the top and narrow at the bottom, forming a roughly Y-shaped structure. Since the mounting seat 42 is located higher and is not affected by the components inside the electrical control box, it can be made wider to accommodate the second wiring harness, while the base 41 can be made narrower to avoid the components inside the electrical control box. It should be noted that the height of the base 41 and mounting seat 42 can be adjusted according to actual needs and is not subject to further restrictions.

[0092] Optionally, in some examples, in the first direction, the width of the seating 42 is 6.7 mm to 7 mm, that is, Figure 6 The distance shown in D7; the width of the limit groove 43 is 3mm-3.5mm, that is, Figure 6 This arrangement can avoid the relevant components in the electric control box as much as possible without affecting the placement of the second wiring harness.

[0093] In order to better constrain the second wire harness, optionally, in one embodiment of the present disclosure, the wire harness fixing device further includes a first wire pressing portion 5 , and in the second direction, the first wire pressing portion 5 is located on one side of the wire harness lifting portion 4 .

[0094] The first pressing portion 5 is connected to the main control board bracket of the electric control box, and a first pressing hook 51 is formed on the first pressing portion 5. The first pressing hook 51 cooperates with the limiting groove 43 to fix the second wire harness. The second direction is parallel to the extending direction of the second wire harness.

[0095] Among them, the first wire pressing part 5 can press the second wire harness downward, and the limiting groove 43 can limit the side and bottom of the second wire harness. Therefore, the cooperation between the first wire pressing part 5 and the limiting groove 43 can realize the constraint of the second wire harness in the up and down directions, so that the second wire harness is arranged along the designed direction. In some examples, the first wire pressing part 5 and the wire harness lifting part 4 are arranged in parallel. In the second direction, the straight-line distance between the first wire pressing part 5 and the wire harness lifting part 4 is 17.5mm-18mm. That is, Figure 7 The distance shown in D6.

[0096] It is understood that the first pressing hook 51 has a hook groove, and the second wire harness can be located in the hook groove of the first pressing hook 51. As the first pressing hook 51 is hooked, it is pressed downward to produce a restraining effect on the second wire harness. The bottom of the hook groove of the first pressing hook 51 is higher than the bottom of the limiting groove 43.

[0097] A second aspect of the present disclosure further provides an electric control box main control board bracket, comprising the above-mentioned wire harness fixing device.

[0098] In order to meet the needs of more wiring harness routing, optionally, in one embodiment of the present disclosure, the main control board bracket of the electric control box includes a bracket body 6, a side wall of the bracket body 6 is provided with a second base 7, and a third wiring groove 71 is opened on the second base 7. The third wiring groove 71 is used for routing the third wiring harness, and a groove 61 is provided on the side wall of the bracket body 6 opposite to the second base 7. The groove 61 is used for allowing part of the third wiring harness to enter the bracket body 6.

[0099] The third wiring trough 71 can constrain the third wiring harness disposed therein, ensuring that the third wiring harness is routed along a predetermined path. It is understood that the third wiring trough 71 can accommodate the third wiring harness. The third wiring trough 71 can be formed by a downwardly concave groove in the second base 7, and the third wiring harness can be placed directly within the third wiring trough 71.

[0100] Among them, the side wall of the bracket body 6 is provided with a groove 61, which is connected to the third wiring groove 71, so that part of the third wiring harness in the third wiring groove 71 can enter the bracket body 6 through the groove 61, thereby reducing the size of the second base 7, so that the components close to the second base 7 in the electrical control box can be avoided, and the space can be better utilized.
