TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling equipment, in particular to a machine head wire arrangement and an air supply device. BACKGROUND

[0002] At present, fan products are gradually improved to meet the needs of users in folding storage. In related technologies, some fans use a manual folding mode, which can easily cause a hand clamping phenomenon during folding. However, using an automatic folding mode, the wire body can easily twist, bend, and other phenomena during folding or head shaking, and long-term operation can easily cause wire breakage. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a machine head wire arrangement and an air supply device to solve the problem of easy wire breakage of the automatic folding fan.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0005] In a first aspect, the present application provides a machine head wire arrangement, comprising:

[0006] a support frame, which is provided with a plurality of first wire grooves and a first wire hole, the first wire hole being arranged at one end of the support frame;

[0007] a connecting seat, which is rotationally connected with the end of the support frame provided with the first wire hole, the connecting seat being provided with a plurality of second wire grooves and a second wire hole, the second wire hole penetrating through the connecting seat along the direction of gravity; and

[0008] a wire body, which is sequentially arranged through each of the first wire grooves, the first wire hole, each of the second wire grooves, and the second wire hole;

[0009] Wherein, the support frame can be controlled to rotate relative to the connecting seat, the connecting seat can be controlled to rotate along its own axis, and the two ends of the wire body are fixed by the first wire groove and the second wire groove respectively, so as to limit the bending of the wire body during the rotation of the support frame or the connecting seat.

[0010] Through the above design, during the folding of the support frame or the rotation of the connecting seat, the wire body will not be twisted greatly due to the pulling of the two ends, thereby reducing the risk of breakage of the wire body.

[0011] In one of the embodiments of the first aspect, the head wire structure further comprises a first driving member and a second driving member, both of which are mounted in the connecting seat, the first driving member is in transmission connection with the support frame, and the second driving member is in fixed connection with the connecting seat, and each of the second wire grooves is located on the same side of the first driving member and the second driving member.

[0012] Through the above design, the support frame can be rotated under the driving of the first driving member, thereby driving the fan head to fold or unfold relative to the connecting seat; the second driving member can drive the connecting seat and the support frame as a whole to rotate relative to the machine body, thereby realizing the wind sweeping operation of the fan head.

[0014] Through the above design, when the wire body enters the connecting seat from the support frame, it smoothly enters the third wire hole from the first wire hole and is led out from the third wire hole with a smaller bending angle, thereby reducing the activity amount of the wire body during the rotation of the support frame and reducing the risk of twisting and abrasion of the wire body.

[0015] In one of the embodiments of the first aspect, the wire body comprises a first fixed segment, a first bending segment, a second fixed segment and a second bending segment connected in sequence, the first fixed segment is arranged in the first wire groove, the first bending segment is arranged in the first wire hole and the third wire hole, the second fixed segment is arranged in the second wire groove, and the second bending segment is arranged in the second wire hole.

[0016] Through the above design, the first bending segment and the second bending segment form a certain activity allowance, thereby avoiding excessive tension of the wire body during the turning of the support frame or the rotation of the connecting seat.

[0017] In one of the embodiments of the first aspect, the support frame comprises a first end face, an arc-shaped face and a second end face, the first end face, the arc-shaped face and the second end face are connected in sequence and define the first wire hole, and the two opposite ends of the third wire hole are respectively aligned with the first end face and the second end face.

[0019] In one of the embodiments of the first aspect, the first end surface and the second end surface form a preset included angle a, and satisfy: 120°≤a≤240°.

[0020] Through the above design, the first end surface and the second end surface can limit the overturning angle of the support frame, and further limit the bending angle and displacement of the wire body.

[0021] In one of the embodiments of the first aspect, the first wire hole, the second wire hole and the third wire hole are each provided with a transition fillet on the hole opening side.

[0022] Through the above design, the frictional resistance between the wire body and the side is reduced, and the wear caused by the friction between the wire body and the side is avoided.

[0023] In one of the embodiments of the first aspect, the second wire hole is arranged at a non-axial position of the connecting seat, and the second wire hole has a waist-shaped hole structure.

[0024] Through the above design, the wire body has a certain space for movement during the rotation of the connecting seat, and the problem of wire breakage caused by the twisting and grinding of the wire body during the shaking process is avoided.

[0025] In one of the embodiments of the first aspect, the first wire slot is provided with a v-shaped opening, and the width of the opening is greater than the outer diameter of the wire body.

The wire body sequentially passes through each of the first wiring grooves, first wiring holes, and each of the second wiring grooves and second wiring holes, and both ends of the wire body are fixed by the first wiring grooves and second wiring holes, respectively. In this way, when the support frame is controlled to rotate relative to the connecting seat or the connecting seat is controlled to rotate along its own axis, the wire body will not twist significantly with the support frame or connecting seat, reducing active damage to the wire body, improving the problem of wire breakage caused by long-term operation, and extending the service life of the wire body.

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] See Figure 1 As shown, an embodiment of this application provides a head unit wiring structure 100, which can be used for internal wiring in rotating parts of various electrical appliances, reducing the risk of wire breakage due to folding. It should be noted that, for ease of understanding, this application uses an air supply device as an example application scenario for the head unit wiring structure 100. For example, the air supply device can be a folding fan, but the head unit wiring structure 100 is not limited to applications on fans.

[0047] Specifically, the headstock cable routing structure 100 includes a support frame 110, a connecting seat 120, and a cable body 130. One end of the support frame 110 is rotatably connected to the connecting seat 120, and the cable body 130 is disposed within the support frame 110 and the connecting seat 120, maintaining relative stability. During the rotation of the support frame 110 and the connecting seat 120, the bending motion of the cable body 130 is minimal, reducing torsional wear.

[0048] For example, the end of the support frame 110 away from the connecting seat 120 is connected to the fan head, and the support frame 110 can be controlled to rotate relative to the connecting seat 120, so that the fan head can be unfolded or folded relative to the connecting seat 120 by the rotation of the support frame 110. The fan head is the air supply component of the fan, which includes a motor and fan blades to realize indoor air supply operation; the specific structure is not detailed here. The top of the connecting seat 120 is connected to the support frame 110, and the bottom is mounted on the fan body support rod. At the same time, the connecting seat 120 can be controlled to rotate along its own axis, thereby driving the fan head to oscillate during the operation of the fan. It is understood that in order to ensure the normal operation of the various components of the fan head, relevant electronic components and wires 130 need to be installed inside the support frame 110 and the connecting seat 120 to conduct electricity through the wires 130, so that the internal electronic components need to be electrically connected, and therefore the internal wires 130 need to be protected against breakage.

[0049] Continue reading Figure 2 As shown, to achieve the above objectives, the support frame 110 is provided with multiple first cable routing grooves 111 and first cable routing holes 112. The first cable routing holes 112 are located at the end of the support frame 110 that is rotatably engaged with the connecting seat 120. The connecting seat 120 is rotatably connected to the end of the support frame 110 with the first cable routing holes 112, and is provided with multiple second cable routing grooves 121 and second cable routing holes 122. The cable body 130 sequentially passes through each of the first cable routing grooves 111, the first cable routing holes 112, each of the second cable routing grooves 121, and the second cable routing holes 122.

[0050] Specifically, the two ends of the cable 130 are fixed by the first cable routing groove 111 and the second cable routing groove 121, respectively. Therefore, during the folding process of the support frame 110, the cable 130, under the tension at both ends, will not twist significantly with the movement of the support frame 110, thus reducing the risk of cable breakage. The second cable routing hole 122 passes through the connector 120 along the direction of gravity to connect with the electronic components in the fan body after passing through the connector, enabling circuit conduction in the fan head. Similarly, when the cable 130 is fixed by the second cable routing groove 121, when the connector 120 drives the support frame 110 to rotate, the portion of the cable 130 located within the second cable routing hole 122 will not twist, but will only move within the second cable routing hole 122, reducing the risk of breakage.

[0051] Continue reading Figure 3 As shown, the head cabling structure 100 further includes a first drive member 140 and a second drive member 150, both installed within the connecting seat 120. The first drive member 140 is connected to the support frame 110 in a transmission manner, and the second drive member 150 is fixedly connected to the connecting seat 120. Each second cabling groove 121 is located on the same side of the first drive member 140 and the second drive member 150.

[0052] Specifically, both the first drive member 140 and the second drive member 150 can be rotary motors, controlling the rotation of the support frame 110 and the connecting seat 120 respectively. The first drive member 140 is fixed to the end of the connecting seat 120 near the support frame 110, and its output end is equipped with a bevel gear. The end of the support frame 110 connected to the connecting seat 120 also has a bevel gear. Through the transmission of the bevel gears, the support frame 110 can rotate under the drive of the first drive member 140, thereby causing the fan head to fold or unfold relative to the connecting seat 120. The second drive member 150 is installed in the middle of the connecting seat 120 and connected to the fan body via a transmission component, driving the connecting seat 120 and the support frame 110 to rotate relative to the fan body, thus achieving the fan head's sweeping operation.

[0053] Accordingly, in order to facilitate the spatial layout of the cable 130 within the connector 120, each of the second cable routing grooves 121 is located on the same side of the first drive member 140 and the second drive member 150. In this way, the cable 130 is distributed in a straight line within the connector 120, avoiding excessive bending and winding of the cable 130 to avoid the first drive member 140 and the second drive member 150, reducing the amount of movement of the cable 130 during operation, and further reducing the risk of breakage of the cable 130.

[0054] For example, the first cable tray 111 and the second cable tray 121 can be formed by combining multiple ribs set in the support frame 110 and the connecting seat 120, respectively. Of course, other tray configuration methods can also be used, which will not be described in detail here.

[0055] Continue reading Figure 4 As shown, the first cable tray 111 is further provided with a V-shaped opening, the width of which is greater than the outer diameter of the cable body 130.

[0056] Specifically, the V-shaped opening facilitates the placement of the cable 130 into the first cable routing groove 111 from the wider opening side. Simultaneously, the bottom width of the first cable routing groove 111 is the same as or slightly larger than the outer diameter of the cable 130, thus clamping the cable 130 within the first cable routing groove 111. Preferably, the groove width of the first cable routing groove 111 can be 0.1mm-0.2mm larger than the diameter of the cable 130, which allows for placement of the cable 130 while limiting its range of motion, preventing significant displacement of the cable 130 during rotation of the support frame 110 and thus avoiding the risk of breakage due to tension.

[0057] It is understandable that the second wiring groove 121 can have the same structural configuration as the first wiring groove 111 in order to fix the wire 130 in the connector 120. The specific principle is the same as that in the above embodiment, and will not be repeated here.

[0058] Continue reading Figure 5 As shown, in some embodiments, the support frame 110 is also provided with a third wiring hole 113. The third wiring hole 113 is provided at the end of the support frame 110 where the first wiring hole 112 is provided. The first wiring hole 112 and the third wiring hole 113 are connected and located on two intersecting planes respectively. The wire 130 passes through the third wiring hole 113.

[0059] Specifically, the end of the support frame 110 connected to the connecting seat 120 is provided with a connecting shaft, which connects the support frame 110 to the connecting seat 120 and can rotate along the axis of the connecting shaft. A third wiring hole 113 is formed on the connecting shaft and is adjacent to the first wiring hole 112, to guide the cable 130 from the support frame 110 to the connecting seat 120. The first wiring hole 112 and the third wiring hole 113 are located in two intersecting planes, allowing the cable 130 to smoothly enter the third wiring hole 113 from the first wiring hole 112 when it enters the connecting seat 120 from the support frame 110, and to exit from the third wiring hole 113 with a smaller bending angle. This reduces the amount of movement of the cable 130 during the rotation of the support frame 110 and reduces the risk of torsional wear on the cable 130.

[0060] Continue reading Figure 6 As shown, preferably, the plane where the first wiring hole 112 is located is perpendicular to the plane where the third wiring hole 113 is located, so as to reduce the laying length of the cable 130 and facilitate the mass production of the support frame 110, thereby reducing production costs.

[0061] Furthermore, the width of the third wiring hole 113 is greater than the outer diameter of the cable body 130, thereby giving the cable body 130 a certain amount of room to move within the third wiring hole 113. This prevents the cable body 130 from being too tight at the bend, causing it to stick tightly to the port wall of the first wiring hole 112, reducing wear and tear, and further reducing the risk of breakage of the cable body 130.

[0062] Preferably, the width of the third wiring hole 113 is 8mm-10mm to accommodate the installation of most sizes of cable bodies 130. The specific value can be reasonably selected according to the actual size of the cable body 130.

[0063] In some embodiments, the support frame 110 includes a first end face 114, an arcuate surface 115, and a second end face 116. The first end face 114, the arcuate surface 115, and the second end face 116 are connected in sequence and define a first wiring hole 112. The two opposite ends of the third wiring hole 113 are aligned with the first end face 114 and the second end face 116, respectively.

[0064] Specifically, the first end face 114, the arc-shaped surface 115, and the second end face 116 are sequentially distributed on three adjacent sides of the first wiring hole 112, and the other side of the first wiring hole 112 is connected to the third wiring hole 113. The first end face 114 and the second end face 116 are used to limit the movement angle of the cable 130, preventing large displacement of the cable 130 and reducing the risk of cable breakage due to tension. In the folded or unfolded state of the support frame 110, the cable 130 abuts against the first end face 114 and the second end face 116 respectively, thereby limiting the movement angle of the cable 130 and reducing cable breakage due to tension.

[0065] Furthermore, since both ends of the cable 130 are restricted, a certain amount of slack is reserved at the third cable routing hole 113 to prevent the cable 130 from being worn due to excessive tension during the rotation of the support frame 110. Similarly, a certain amount of slack is also reserved at the second cable routing hole 122 to reduce damage to the cable 130 during the rotation of the connecting seat 120.

[0066] Furthermore, the first end face 114 and the second end face 116 form a preset included angle α, satisfying: 120°≤α≤240°.

[0067] For example, the first end face 114 and the second end face 116 can be used to limit the curvature of the arc surface 115, so as to limit the bending angle and displacement of the line 130 according to the flipping angle of the support frame 110. The preset included angle can be 120°, 150°, 180°, 210°, 240°, etc., and can be selected according to actual needs. During the rotation of the support frame 110, the first end face 114 or the second end face 116 abuts against the line 130 only by flipping the support frame 110, and the movement of the line 130 is small, reducing the movement loss of the line 130.

[0068] Furthermore, the opening edges of the first wiring hole 112, the second wiring hole 122, and the third wiring hole 113 are all provided with transition rounded corners.

[0069] Understandably, during the rotation of the support frame 110 or the connecting seat 120, the cable 130 will inevitably come into contact with the sides of the first cable hole 112, the second cable hole 122 and the third cable hole 113. By setting the transition rounded corners, the frictional resistance between the cable 130 and the sides is reduced, and wear caused by friction between the cable 130 and the sharp edges is avoided.

[0070] In some embodiments, the cable 130 includes a first fixed section 131, a first bent section 132, a second fixed section 133, and a second bent section 134 connected in sequence. The first fixed section 131 is engaged in the first cable routing groove 111, the first bent section 132 passes through the first cable routing hole 112 and the third cable routing hole 113, the second fixed section 133 is engaged in the second cable routing groove 121, and the second bent section 134 passes through the second cable routing hole 122.

[0071] Specifically, one end of the first fixed section 131 extends from one end of the support frame 110 and the connecting seat 120 to connect with the electronic components of the fan head. The other end is sequentially inserted into the first wiring groove 111 and extends along the direction of the first wiring hole 112. The first bent section 132 passes through the first wiring groove 111 and the third wiring groove, connecting the first fixed section 131 and the second fixed section 133. The first bent section 132 has a certain amount of flexibility to prevent the wire 130 from becoming excessively taut during the rotation of the support frame 110 when the first fixed section 131 and the second fixed section 133 are restricted, thus facilitating the rotation of the support frame 110. Similarly, the second bent section 134 also has a certain amount of flexibility to prevent the wire 130 from becoming excessively taut and breaking during the rotation of the connecting seat 120 when the second fixed section 133 is restricted by the second wiring groove 121.

[0072] Continue reading Figure 7 As shown, in some embodiments, the second wiring hole 122 is disposed on the non-axial part of the connector 120, and the second wiring hole 122 has an oblong hole structure.

[0073] Specifically, due to the eccentric setting of the second wiring hole 122, the waist-shaped hole structure of the second wiring hole 122 allows the cable 130 to have a certain amount of room to move during the rotation of the connector 120, thus avoiding the problem of the cable 130 twisting and grinding during the swaying process, which could lead to the cable breaking.

[0074] Preferably, the two opposite sides of the second wiring hole 122 in the width direction are arranged in an arc shape to accommodate the movement of the wire 130 during the rotation of the connector 120.

[0075] In other embodiments, the second wiring hole 122 may be located at the axis of the connector 120 to minimize the torsional wear of the cable 130.

[0076] Embodiments of this application also provide an air supply device, including the head wiring structure 100 in any of the above embodiments.
