Description

Technical Field

[0001] This utility model relates to the field of wire harness guiding technology, and in particular to a wire passing structure and a range hood having the same. Background Technology

[0002] Some electrical appliances consist of a hinged first part and a second part, with electrical components located on the second part. Wiring harnesses need to extend from the first part to both. Taking a range hood as an example, range hoods are becoming increasingly slim. When turned on, a rotating flap is used to collect smoke, and the flap integrates control buttons. The wiring harnesses for the electrical components on the flap need to be guided to the main body of the range hood. Due to space constraints, this is typically achieved using a connecting rod mechanism. However, the rotation of the connecting rod causes significant vertical displacement of the wiring harness, making it prone to damage. Utility Model Content

The sliding assembly has a wire harness fixing structure so that the wire harness extends along the sliding assembly from the first part to the second part. The sliding assembly includes a second guide surface, which slides in contact with the first guide surface. When the second part rotates relative to the first part, the sliding assembly rotates relative to the second part and slides relative to the guide member. The distance from the sliding contact point between the second guide surface and the first guide surface to a first reference line changes with the movement of the first end so that the maximum distance the second end moves in the vertical direction is within a set range. The first reference line is a line perpendicular to the rotation axis of the second end and the first end.

[0008] In an optional embodiment, the wire harness fixing structure includes:

[0009] A groove extends from the first end to the second end; at the first end, the groove has an arc segment that surrounds the rotation axis of the sliding assembly.

[0010] In an optional embodiment, the wire harness fixing structure includes:

[0011] Limiting protrusions are provided on both sides of the groove, and the limiting protrusions on both sides of the groove are staggered.

[0012] In an optional embodiment, the second guide surface extends from the first end to the second end in at least one of the following: a straight line, a curve, or a combination of a straight line and a curve. The distance from the second guide surface to the first reference line gradually increases from the second end to the first end.

[0013] In an optional embodiment, the sliding component includes:

[0014] The wire guide portion has a wire harness fixing structure disposed on it so that the wire harness is fixed on the wire guide portion from the second end to the first end.

[0018] In an optional embodiment, the position of the first guide surface in the vertical direction is not lower than the lowest point of the rotation axis movement of the sliding component, and not higher than the highest point of the rotation axis movement of the sliding component.

[0019] In an optional embodiment, the guide includes:

[0020] A guide portion, which is horizontally arranged, and the aforementioned first guide surface is disposed on the aforementioned guide portion;

[0021] A first limiting part is connected to one end of the guide part, and the first limiting part extends towards one side of the guide part at a certain angle to the guide part;

[0022] The second limiting part is connected to the other end of the guide part. The second limiting part extends towards one side of the guide part at a certain angle to the guide part. The first limiting part and the second limiting part are located on the same side of the guide part. The sliding component is located between the first limiting part and the second limiting part.

[0023] In an optional embodiment, the first guide surface is an arc surface.

[0024] Secondly, this utility model embodiment provides a range hood, including a first part and a second part that are hinged together.

[0026] In the wire-passing structure of this embodiment, the guide member is connected to the first part and includes a first guide surface; the sliding component includes a first end and a second end opposite to each other, the first end being rotatably connected to the second part, and the second end being located on the side of the guide member away from the first end. The sliding component has a wire harness fixing structure so that the wire harness extends from the first part to the second part along the sliding component. The sliding component includes a second guide surface, which slides in contact with the first guide surface. When the second part rotates relative to the first part, the sliding component rotates relative to the second part and slides relative to the guide member. The distance from the sliding contact point between the second guide surface and the first guide surface to the first reference line changes with the movement of the first end, so that the maximum distance the second end moves in the vertical direction is within a set range.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0039] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0040] This utility model embodiment provides a wiring structure for use in electrical equipment, which includes a first part 100 and a second part 200 hinged together. The wiring structure allows wires to pass between the first part 100 and the second part 200, enabling a wire harness 400 to extend from the first part 100 to the second part 200 along the wiring structure. The first part 100 can be the main body of the electrical equipment, and the second part 200 can be a door, cover, or flap, etc., of the electrical equipment. The electrical equipment can include kitchen appliances, such as range hoods. The wiring structure of this utility model embodiment is described below using a range hood as an example. The first part 100 can be the main body of the range hood, and the second part 200 can be a smoke-collecting plate. The smoke-collecting plate rotates relative to the main body of the range hood, allowing the range hood to switch between a working mode and a dormant mode, ensuring good smoke extraction. A button operation area can be integrated on the smoke-collecting plate, and the wire harness 400 extends from the main body of the range hood along the wiring structure to the smoke-collecting plate.

[0041] See Figures 1 to 9 The wire-passing structure of this utility model embodiment includes a guide 1 and a sliding component 2. The guide 1 is connected to the first part 100 and includes a first guide surface 11.

[0042] The sliding assembly 2 includes a first end 21 and a second end 22 opposite to each other. The first end 21 is rotatably connected to the second part 200, and the second end 22 is located on the side of the guide member 1 away from the first end 21. The sliding assembly 2 has a wire harness fixing structure 3 so that the wire harness 400 extends along the sliding assembly 2 from the first part 100 to the second part 200.

[0043] The first end 21 of the sliding assembly 2 is connected to the second part 200, and the second end 22 is connected to the guide 1 located in the first part 100, thereby forming a bridge between the first part 100 and the second part 200 for wiring of the wire harness 400, which can extend along the sliding assembly 2 from the first part 100 to the second part 200.

[0044] The sliding component 2 includes a second guide surface 23, which slides in contact with the first guide surface 11. When the second part 200 rotates relative to the first part 100, the sliding component 2 rotates relative to the second part 200 and slides relative to the guide member 1. The sliding component 2 slides in contact with the guide member 1, thus adapting to the rotation of the second part 200 relative to the first part 100. Driven by the second part 200, the sliding component 2 slides relative to the guide member 1, and may also rotate relative to the guide member 1. Sliding the sliding component 2 relative to the guide member 1 causes the second end 22 to move horizontally, and rotating the sliding component 2 relative to the guide member 1 causes the second end 22 to move vertically. The vertical movement of the second end 22 causes greater damage to the wire harness 400 at the second end 22 than the horizontal movement. The distance from the sliding contact point between the second guide surface 23 and the first guide surface 11 to the first reference line 300 changes with the movement of the first end 21, so that the maximum distance the second end 22 moves in the vertical direction is within a set range. The first reference line 300 is the vertical line connecting the second end 22 and the rotation axis of the sliding component 2.

[0045] The wire-passing structure of this utility model embodiment designs the shape of the second guide surface 23 so that the distance from the sliding contact point between the second guide surface 23 and the first guide surface 11 to the first reference line 300 changes with the movement of the first end 21. This allows the maximum distance the second end 22 moves in the vertical direction to be within a set range, avoiding damage to the wire harness 400 caused by excessive vertical movement of the second end 22. By controlling the maximum vertical movement of the second end 22 within a small set range, the service life of the wire harness 400 can be extended.

[0046] See Figure 8 and Figure 9 Taking range hoods as an example, among which Figure 8 The smoke collection plate rotates relative to the main body of the smoke machine to the open position. Figure 9The smoke-gathering plate is rotated relative to the main body of the range hood to a closed state. The guide member 1 is connected to the main body of the range hood. The first end 21 of the sliding component 2 is rotatably connected to the smoke-gathering plate, and the second end 22 is in sliding contact with the guide member 1. Due to the trend towards ultra-thin range hoods and limited internal space, the wiring harness 400's routing method is restricted. The routing structure of this embodiment can adapt to the spatial structure of the range hood. The upper end of the smoke-gathering plate is hinged to the main body of the range hood. The smoke-gathering plate rotates relative to the main body of the range hood to a smoke-gathering state, forming a smoke inlet between the lower end of the smoke-gathering plate and the main body of the range hood. During the rotation of the smoke-gathering plate relative to the main body of the range hood to open or close, the first end 21 of the sliding component 2 moves with the smoke-gathering plate, and the trajectory of the first end 21 is an arc. In the horizontal direction, the first end 21 moves closer to or further away from the guide member 1; in the vertical direction, the position of the first end 21 relative to the guide member 1 changes. The movement of the first end 21 will affect the position of the second end 22 in the vertical direction. In this embodiment of the present invention, the shape of the second guide surface 23 along the first end 21 to the second end 22 is adapted to the movement of the first end 21, so as to at least partially offset the influence of the movement of the first end 21 on the position of the second end 22 in the vertical direction, so that the maximum distance of the second end 22 moving in the vertical direction is controlled within a set range.

[0047] In specific implementation, when the movement of the first end 21 lowers its position in the vertical direction, it causes the second end 22 to move upward in the vertical direction. This reduces the distance from the sliding contact point between the second guide surface 23 and the first guide surface 11 to the first reference line 300, which can at least partially offset the upward movement of the second end 22 in the vertical direction. This reduces the vertical movement distance of the second end 22, or prevents its position in the vertical direction from changing with the movement of the first end 21. Of course, when the contact point between the sliding assembly 2 and the guide member 1 and the rotation axis of the first end 21 are not on the same horizontal plane, the horizontal movement of the first end 21 will also cause the second end 22 to move in the vertical direction.

[0048] When the movement of the first end 21 raises its position in the vertical direction, and when the movement of the first end 21 causes the second end 22 to move downward in the vertical direction, the distance from the sliding contact point between the second guide surface 23 and the first guide surface 11 to the first reference line 300 decreases. This can at least partially offset the distance the second end 22 moves downward in the vertical direction, thereby reducing the distance the second end 22 moves downward in the vertical direction, or ensuring that the position of the second end 22 in the vertical direction does not change with the movement of the first end 21.

[0049] Of course, when the contact point between the sliding component 2 and the guide 1 and the rotation axis of the first end 21 are not on the same horizontal plane, the horizontal movement of the first end 21 will also cause the second end 22 to move in the vertical direction. The distance between the second guide surface 23 and the first reference line 300 can be designed with reference to the above embodiment, and will not be described in detail here.

[0050] In some embodiments, see Figures 1 to 4 The wire harness fixing structure 3 includes a wire groove 31, which extends from a first end 21 to a second end 22. The wire harness 400 is disposed within the wire groove 31, which protects the wire harness 400 from damage such as scratches. The wire groove 31 extending from the first end 21 to the second end 22 provides greater protection for the wire harness 400 as it extends from the first portion 100 to the second portion 200.

[0051] In some embodiments, see Figure 4 At the first end 21, the wire groove 31 has an arc segment that surrounds the rotation axis of the sliding component 2. By setting the arc segment, the wire harness 400 makes a smaller bend under the guiding constraint of the arc segment, and the minimum bending radius is limited, thus preventing the wire harness 400 at the first end 21 from having an excessively small bending radius or excessive bending, thereby protecting the wire harness 400. The arc segment at the first end 21 of the wire groove 31 surrounding the rotation axis of the sliding component 2 can prevent the wire harness 400 in this area from having an excessively small bending radius or excessive bending during movement, thereby protecting the wire harness 400. In specific implementation, the center of the arc segment coincides with the rotation axis of the moving component.

[0052] In some embodiments, see Figure 1 The wire harness fixing structure 3 includes limiting protrusions 32, which are located on both sides of the wire groove 31 and are staggered. The staggered limiting protrusions 32 allow the wire harness 400 to be inserted into the wire groove 31 from the opening, and the limiting protrusions 32 can stably press the wire harness 400 in place, preventing it from moving around in the groove.

[0053] In this embodiment of the present invention, the distance from the sliding contact point between the second guide surface 23 and the first guide surface 11 to the first reference line 300 changes with the movement of the first end 21. Specifically, the second guide surface 23 may exhibit a certain linear change along the direction from the first end 21 to the second end 22.

[0054] In some embodiments, the second guide surface 23 extends from the first end 21 to the second end 22 in at least one of the following: a straight line, a curve, or a combination of a straight line and a curve.

[0055] For example, the second guide surface 23 may extend in a straight line from the first end 21 to the second end 22, and the second guide surface 23 may form a certain angle with the first reference line 300, so as to at least partially offset the positional change of the second end 22 in the vertical direction caused by the movement of the first end 21.

[0056] The second guide surface 23 can extend in multiple segments in a straight line from the first end 21 to the second end 22. The second guide surface 23 as a whole extends in a broken line. The angle formed between the second guide surface 23 and the first reference line 300 in different segments can be different, which can better offset the positional change of the second end 22 in the vertical direction caused by the movement of the first end 21.

[0057] The second guide surface 23 can extend in a curved direction from the first end 21 to the second end 22. The curved extension of the second guide surface 23 can better match the vertical position change of the second end 22 caused by the movement of the first end 21. Throughout the entire movement process, it can better counteract the vertical position change of the second end 22 caused by the movement of the first end 21.

[0058] The second guide surface 23 can extend partly in a straight line and partly in a curve from the first end 21 to the second end 22, so as to match the position change of the second end 22 in the vertical direction caused by the movement of the first end 21. In the whole process, it can better counteract the position change of the second end 22 in the vertical direction caused by the movement of the first end 21.

[0059] The sliding component 2 can be located near the hinge between the first part 100 and the second part 200. When the second part 200 rotates relative to the first part 100, the distance that the sliding component 2 moves with the second part 200 can be reduced, thereby reducing the space occupied by the wire-passing structure.

[0060] In some embodiments, see Figure 4 and Figure 5 The distance from the second guide surface 23 to the first reference line 300 gradually increases from the second end 22 to the first end 21. This allows the first end 21 to be positioned closer to the hinge between the first part 100 and the second part 200, reducing the distance the sliding component 2 moves with the second part 200 and reducing the space occupied by the through-line structure.

[0061] In an exemplary embodiment, the distance from the second guide surface 23 to the first reference line 300 can be gradually increased from the second end 22 to the first end 21 in the direction of a straight line, a curve, or a combination of a straight line and a curve.

[0062] In some embodiments, the position of the first guide surface 11 in the vertical direction is not lower than the lowest point of the rotation axis movement of the sliding component 2, and not higher than the highest point of the rotation axis movement of the sliding component 2. In this embodiment of the present invention, by limiting the relative position of the first guide surface 11 with the highest and lowest points of the rotation axis movement of the sliding component 2, the influence of the vertical movement of the first end 21 on the vertical displacement of the second end 22 can be reduced.

[0063] In some embodiments, see Figure 5The sliding component 2 includes a wire guide portion 24, and a wire harness fixing structure 3 is disposed on the wire guide portion 24 so that the wire harness 400 is fixed on the wire guide portion 24 from the second end 22 to the first end 21. The wire guide portion 24 is rotatably connected to the second part 200, and the side of the wire guide portion 24 that slides in contact with the first guide surface 11 forms a second guide surface 23. In this embodiment of the present invention, the wire guide portion 24 may be a long strip-shaped rod, with the length direction of the wire guide portion 24 from the first end 21 to the second end 22. A wire groove 31 is opened along the length direction of the wire guide portion 24, and the wire harness 400 is installed in the wire groove 31.

[0064] In a specific implementation, the first end 21 may have a first bend, which bends the first end 21 toward the side of the wire-passing part 24, so that the side of the wire-passing part 24 opposite to the bending direction of the first bend can slide into contact with the guide member 1 to form a second guide surface 23.

[0065] The first end 21 can form an arc segment around the rotation axis of the sliding component 2, and the wire groove 31 opened on it is also an arc segment. When the sliding component 2 rotates around the rotation axis, the wire harness 400 bends slightly under the constraint of the arc segment, and the minimum bending radius is limited. This can prevent the head wire harness 400 from having too small a bending radius and excessive bending, thereby protecting the wire harness 400.

[0066] By eccentrically arranging the sliding component 2 around the rotation axis and the wire guide portion 24, a second guide surface 23 is formed on the side of the wire guide portion 24 that slides in contact with the first guide surface 11, thus simplifying the structure of the sliding component 2.

[0067] In some embodiments, see Figures 1 to 4 The sliding component 2 includes a wire guide portion 24 and a sliding portion 25. A wire harness fixing structure 3 is disposed on the wire guide portion 24 so that the wire harness 400 is fixed on the wire guide portion 24 from the second end 22 to the first end 21. The wire guide portion 24 is rotatably connected to the second part 200. The wire guide portion 24 may be a long strip-shaped rod, with the first end 21 to the second end 22 forming the length direction of the wire guide portion 24. A wire groove 31 is formed along the length direction of the wire guide portion 24, and the wire harness 400 is installed in the wire groove 31.

[0068] The first end 21 can form an arc segment around the rotation axis of the sliding component 2, and the wire groove 31 opened on it is also an arc segment. When the sliding component 2 rotates around the rotation axis, the wire harness 400 bends slightly under the constraint of the arc segment, and the minimum bending radius is limited. This can prevent the head wire harness 400 from having too small a bending radius and excessive bending, thereby protecting the wire harness 400.

[0069] The sliding part 25 is connected to the wire guide part 24. The side of the sliding part 25 facing away from the wire guide part 24 slides in contact with the guide member 1, forming a second guide surface 23. By providing the sliding part 25 on one side of the wire guide part 24, the position of the rotation axis of the sliding assembly 2 can be flexibly set, and the shape of the second guide surface 23 extending from the first end 21 to the second end 22 can be flexibly set. The shape of the second guide surface 23 extending from the first end 21 to the second end 22 can be any straight line, curve, or a combination of straight lines and curves.

[0070] In some embodiments, see Figure 6 and Figure 7 The guide member 1 includes a guide portion 12, a first limiting portion 13, and a second limiting portion 14. The guide portion 12 is horizontally positioned, and a first guide surface 11 is disposed on the guide portion 12. The guide portion 12 is in slidable contact with the sliding assembly 2. The first limiting portion 13 is connected to one end of the guide portion 12 and extends towards one side of the guide portion 12 at a certain angle. The second limiting portion 14 is connected to the other end of the guide portion 12 and extends towards one side of the guide portion 12 at a certain angle. The first limiting portion 13 and the second limiting portion 14 are located on the same side of the guide portion 12, and the sliding assembly 2 is located between the first limiting portion 13 and the second limiting portion 14. The guide portion 12, the first limiting portion 13, and the second limiting portion 14 are located on the same plane and can be arranged in a U-shape. Under the constraint of the guide member 1, the sliding assembly 2 can slide and rotate relative to the guide member 1 without shifting.

[0071] The first limiting part 13 and the second limiting part 14 are respectively at a certain angle to the guide part 12. In a specific implementation, the first limiting part 13 and the second limiting part 14 can be perpendicular to the guide part.

[0072] In some embodiments, see Figure 6 and Figure 7 The guide member 1 may further include a connecting portion 15, which connects to the first limiting portion 13 and the second limiting portion 14 respectively. The guide member 1 is ring-shaped. In a specific implementation, the first limiting portion 13, the guide portion 12, the second limiting portion 14 and the connecting portion 15 are connected in sequence to form a rectangular ring.

[0073] In some embodiments, see Figure 1 , Figure 3 , Figure 6 and Figure 7 The first guide surface 11 is located on the guide portion 12, and the surface portion of the guide portion 12 slides in contact with the sliding assembly 2 to form the first guide surface 11.

[0074] In some embodiments, see Figure 1 , Figure 4 and Figure 7The first guide surface 11 is an arc surface. In a specific implementation, the first guide surface 11 can be a cylindrical surface. The fact that the first guide surface 11 is an arc surface can reduce the influence of the first guide surface 11 on the sliding component 2 when the sliding component 2 rotates relative to the guide member 1.
