Technical Field

[0001] The present application relates to the technical field of cooling equipment, and in particular to a head wiring structure and an air supply device. Background Art

[0002] At present, fan products are gradually being improved to meet the needs of users in terms of folding and storage. In related technologies, some fans use manual folding, which can easily cause hand pinching during the folding process. With automatic folding, the wire body is prone to twisting, bending, etc. during folding or shaking, and the wire is prone to breakage during long-term operation. Summary of the invention

[0003] Based on this, it is necessary to provide a head wiring structure and air supply device to address the problem that the fan is easily broken when it is automatically folded.

[0004] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0005] In a first aspect, an embodiment of the present application provides a head wiring structure, including:

[0006] A support frame, which is provided with a plurality of first wiring grooves and first wiring holes, wherein the first wiring hole is arranged at one end of the support frame;

[0007] A connecting seat, which is rotatably connected to one end of the supporting frame provided with the first wiring hole, the connecting seat is provided with a plurality of second wiring grooves and second wiring holes, and the second wiring holes penetrate the connecting seat along the gravity direction; and

[0008] A wire body, which is sequentially penetrated by each of the first wiring grooves, the first wiring hole, each of the second wiring grooves and the second wiring hole;

[0009] Among them, the support frame can be controlled to rotate relative to the connecting seat, and the connecting seat can be controlled to rotate along its own axis. The two ends of the wire body are respectively fixed by the first wiring groove and the second wiring groove 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 significantly due to the movement of the support frame or the connecting seat due to the traction at both ends, thereby reducing the risk of breakage of the wire body.

[0011] In one of the embodiments of the first aspect, the head wiring structure also includes a first driving member and a second driving member both installed in the connecting seat, the first driving member is transmission-connected to the support frame, the second driving member is fixedly connected to the connecting seat, and each of the second wiring 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 rotate under the drive 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 to rotate as a whole relative to the fuselage, thereby realizing the wind sweeping operation of the fan head.

[0013] In one of the embodiments of the first aspect, the support frame is further provided with a third wiring hole, and the third wiring hole is arranged at one end of the support frame where the first wiring hole is provided, the first wiring hole is connected to the third wiring hole and are respectively located in two intersecting planes, and the wire body is passed through the third wiring hole.

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

[0015] In one of the embodiments of the first aspect, the wire body includes a first fixed section, a first bending section, a second fixed section and a second bending section connected in sequence, the first fixed section is clamped in the first wiring groove, the first bending section is passed through the first wiring hole and the third wiring hole, the second fixed section is clamped in the second wiring groove, and the second bending section is passed through the second wiring hole.

[0016] Through the above design, the first bending section and the second bending section form a certain amount of margin, so as to prevent the wire from being overly tight during the flipping of the support frame or the rotation of the connecting seat.

[0017] In one of the embodiments of the first aspect, the support frame includes a first end face, a curved face and a second end face, the first end face, the curved face and the second end face are sequentially connected and define the first wiring hole, and the two opposite ends of the third wiring hole are respectively aligned with the first end face and the second end face.

[0018] Through the above design, the first end face and the second end face limit the movement angle of the wire body, so that the wire body will not produce a large displacement, reducing the risk of the wire body being pulled and broken.

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

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

[0021] In one embodiment of the first aspect, transition fillets are provided on the opening sides of the first wiring hole, the second wiring hole, and the third wiring hole.

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

[0023] In one embodiment of the first aspect, the second wiring hole is disposed at a non-axial portion of the connecting seat, and the second wiring hole has a waist-shaped hole structure.

[0024] Through the above design, the wire body has a certain movable space during the rotation of the connecting seat, thereby avoiding the problem of the wire body being twisted and worn during the shaking process, resulting in the shaking of the wire breaking.

[0025] In one embodiment of the first aspect, the first wiring groove is provided with a V-shaped opening, and the width of the opening is greater than the outer diameter of the wire body.

[0026] The above design facilitates the placement of the wire body into the first wiring groove from the opening side with a larger width.

[0027] In a second aspect, an embodiment of the present application further provides an air supply device, comprising the head wiring structure described in any of the above embodiments.

[0028] Through the above design, the automatic folding of the air supply device is achieved, and the problem of the wire body breaking during the folding process is improved.

[0046] See also Figure 1 As shown, the embodiment of the present application provides a head wiring structure 100, which can be used for internal wiring of rotating parts of various electrical appliances to reduce the accident of wire body 130 breakage caused by folding. It should be noted that, for ease of understanding, the present application uses an air supply device as an example application scenario of the head wiring structure 100. For example, the air supply device can be a folding fan, but the head wiring structure 100 is not limited to application on fans.

[0047] Specifically, the head wiring structure 100 includes a support frame 110, a connection seat 120 and a wire body 130. Among them, one end of the support frame 110 is rotatably connected to the connection seat 120, and the wire body 130 is arranged in the support frame 110 and the connection seat 120 and remains relatively stable. During the rotation operation of the support frame 110 and the connection seat 120, the bending action of the wire body 130 is small, reducing torsional wear.

[0048] Exemplarily, one 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 through the rotation of the support frame 110. The fan head is the air supply component of the fan, which includes a motor and a fan blade to realize the indoor air supply operation. The specific structure is not specifically expanded here. The top of the connecting seat 120 is connected to the support frame 110, and the bottom is installed on the fuselage support rod of the fan. At the same time, the connecting seat 120 can be controlled to rotate along its own axis, so as to drive the fan head to shake its head and sweep the wind during the operation of the fan. It can be 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 set in the support frame 110 and the connecting seat 120, so that the internal electronic components can be conductively connected through the wires 130, and thus the internal wires 130 need to be protected from fracture.

[0049] Continue reading Figure 2 As shown, to achieve the above purpose, the support frame 110 is provided with a plurality of first wiring grooves 111 and first wiring holes 112, and the first wiring hole 112 is provided at one end of the support frame 110 and the connecting seat 120 for rotational cooperation. The connecting seat 120 is rotationally connected to the end of the support frame 110 provided with the first wiring hole 112, and is provided with a plurality of second wiring grooves 121 and second wiring holes 122. The wire body 130 is sequentially penetrated with each first wiring groove 111, the first wiring hole 112, each second wiring groove 121 and the second wiring hole 122.

[0050] Specifically, the two ends of the wire body 130 are fixed by the first wiring groove 111 and the second wiring groove 121 respectively, so that during the folding process of the support frame 110, the wire body 130 will not be twisted significantly with the movement of the support frame 110 due to the traction of the two ends, thereby reducing the risk of breakage of the wire body 130. The second wiring hole 122 passes through the connecting seat 120 in the direction of gravity, so as to connect with the electronic components in the fan body after passing through the connection, so as to achieve circuit conduction of the fan head part. Similarly, when the wire body 130 is fixed by the second wiring groove 121, when the connecting seat 120 drives the support frame 110 to rotate, the part of the wire body 130 located in the second wiring hole 122 will not be twisted, and only move in the second wiring hole 122, reducing the risk of breakage.

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

[0052] Specifically, the first driving member 140 and the second driving member 150 can both be rotating motors, so as to control the rotation operation of the support frame 110 and the connecting seat 120 respectively through the first driving member 140 and the second driving member 150. Among them, the first driving member 140 is fixed to one end of the connecting seat 120 close to the support frame 110, and the output end of the first driving member 140 is provided with a bevel gear, and the end of the support frame 110 connected to the connecting seat 120 is also provided with a bevel gear, so that the support frame 110 can rotate under the drive of the first driving member 140 through the transmission cooperation of the bevel gear, thereby driving the fan head to fold or unfold relative to the connecting seat 120. The second driving member 150 is installed in the middle of the connecting seat 120, and is connected to the body of the fan through a transmission member, so as to drive the connecting seat 120 and the support frame 110 to rotate as a whole relative to the body, thereby realizing the wind sweeping operation of the fan head.

[0053] Accordingly, in order to facilitate the spatial layout of the wire body 130 in the connecting seat 120, each second wiring groove 121 is arranged on the same side of the first driving member 140 and the second driving member 150, so that the wire body 130 is distributed in a straight line in the connecting seat 120, avoiding excessive bending and winding of the wire body 130 to bypass the first driving member 140 and the second driving member 150, reducing the movement of the wire body 130 during operation, and further reducing the risk of breakage of the wire body 130.

[0054] Exemplarily, the first wiring groove 111 and the second wiring groove 121 can be formed by a combination of a plurality of ribs disposed in the support frame 110 and the connecting seat 120, respectively. Of course, other groove body settings can also be adopted, which will not be elaborated in detail here.

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

[0056] Specifically, by setting the V-shaped opening, it is convenient to place the wire body 130 in the first wiring groove 111 from the side of the opening with a larger width. At the same time, the bottom width of the first wiring groove 111 is the same as or slightly larger than the outer diameter of the wire body 130, so that the first wiring groove 111 can clamp the wire body 130. Preferably, the groove width of the first wiring groove 111 can be 0.1mm-0.2mm larger than the diameter of the wire body 130, which can meet the placement of the wire body 130 while limiting the range of movement of the wire body 130, avoiding the wire body 130 from generating a large displacement during the rotation of the support frame 110, causing the risk of pulling and breaking.

[0057] It is understandable that the second wiring groove 121 can have the same structural setting as the first wiring groove 111 to achieve the fixation of the wire body 130 in the connecting seat 120. The specific principle is the same as that of the above embodiment and will not be repeated here.

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

[0059] Specifically, a connecting shaft is provided at one end of the support frame 110 connected to the connecting seat 120, so as to be connected to the connecting seat 120 through the connecting shaft and can rotate along the axis of the connecting shaft. The third wiring hole 113 is provided on the connecting shaft and is arranged adjacent to the first wiring hole 112 to lead the wire body 130 from the support frame 110 to the connecting seat 120. The first wiring hole 112 and the third wiring hole 113 are respectively located in two intersecting planes, so that when the wire body 130 enters the connecting seat 120 from the support frame 110, it smoothly enters the third wiring hole 113 from the first wiring hole 112 and is led out from the third wiring hole 113 at a smaller bending angle, thereby reducing the activity of the wire body 130 during the rotation of the support frame 110 and reducing the risk of torsional wear of the wire body 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 layout length of the wire body 130, facilitate mass production of the support frame 110, and reduce production costs.

[0061] Furthermore, the width of the third wiring hole 113 is greater than the outer diameter of the wire body 130, so that the wire body 130 has a certain amount of space to move in the third wiring hole 113, thereby preventing the wire body 130 from being too tight at the bend, causing the wire body 130 to cling to the port wall of the first wiring hole 112, reducing movement wear and further reducing the risk of breakage of the wire body 130.

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

[0063] In some embodiments, the support frame 110 includes a first end face 114, an arcuate face 115 and a second end face 116. The first end face 114, the arcuate face 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 arcuate face 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 with the third wiring hole 113. Among them, the first end face 114 and the second end face 116 are used to limit the movement angle of the wire body 130, so that the wire body 130 will not produce a large displacement, reducing the risk of the wire body 130 being pulled and broken. In the folded or unfolded state of the support frame 110, the wire body 130 abuts against the first end face 114 and the second end face 116 respectively, thereby limiting the movement angle of the wire body 130 and reducing the pulling damage of the wire body 130.

[0065] Furthermore, since both ends of the wire body 130 are limited, a certain amount of margin is reserved for the wire body 130 at the third wiring hole 113, so that the wire body 130 will not be worn due to excessive tension during the flipping process of the support frame 110. Similarly, a certain amount of margin is also reserved for the wire body 130 at the second wiring hole 122, so as to reduce the damage of the wire body 130 during the rotation process of the connecting seat 120.

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

[0067] Exemplarily, the first end face 114 and the second end face 116 can be used to limit the curvature of the curved surface 115, so as to limit the bending angle and displacement of the wire body 130 according to the flipping angle of the support frame 110. The preset angle can be 120°, 150°, 180°, 210°, 240°, etc., which 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 is only abutted against the wire body 130 by flipping the support frame 110, and the activity of the wire body 130 is small, thereby reducing the activity loss of the wire body 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 fillets.

[0069] It can be understood that during the rotation movement of the support frame 110 or the connecting seat 120, the wire body 130 will inevitably contact the sides of the first wiring hole 112, the second wiring hole 122 and the third wiring hole 113, so that by setting the transition radius, the friction resistance between the wire body 130 and the sides is reduced, thereby avoiding wear caused by friction between the wire body 130 and the sharp edges.

[0070] In some embodiments, the wire body 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 clamped in the first wiring groove 111, the first bent section 132 is passed through the first wiring hole 112 and the third wiring hole 113, the second fixed section 133 is clamped in the second wiring groove 121, and the second bent section 134 is passed through the second wiring hole 122.

[0071] Specifically, one end of the first fixed section 131 extends out of one end of the support frame 110 principle connection seat 120 to connect with the electronic components of the fan head part, and the other end is sequentially clamped in the first wiring groove 111 and extends along the direction of the first wiring hole 112. The first bending section 132 is inserted into the first wiring groove 111 and the third wiring groove, and connects the first fixed section 131 and the second fixed section 133. The first bending section 132 has a certain margin of activity, so as to avoid excessive tension of the wire body 130 during the flipping process of the support frame 110 when the first fixing section 131 and the second fixing section 133 are restricted, so as to facilitate the flipping activity of the support frame 110. Similarly, the second bending section 134 also has a certain margin of activity, so as to avoid the problem of breakage caused by excessive tension of the wire body 130 during the rotation of the connection seat 120 when the second fixing 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 at a non-axial portion of the connecting seat 120 , and the second wiring hole 122 is a waist-shaped hole structure.

[0073] Specifically, due to the eccentric setting of the second wiring hole 122 and the waist-shaped hole structure setting of the second wiring hole 122, the wire body 130 has a certain amount of room to move during the rotation of the connecting seat 120, thereby avoiding the problem of the wire body 130 twisting and wearing during the shaking process, resulting in the wire breaking.

[0074] Preferably, 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 body 130 during the rotation of the connecting seat 120 .

[0075] In addition, in other embodiments, the second wiring hole 122 may be disposed at the axis of the connecting base 120 to minimize the torsional wear problem of the wire body 130 .

[0076] An embodiment of the present application further provides an air supply device, comprising the head wiring structure 100 in any of the above embodiments.

[0077] This embodiment has the machine head wiring structure 100 in any of the above embodiments, and therefore has all the beneficial effects of the machine head wiring structure 100 in any of the above embodiments, which will not be described in detail here.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
