Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to lifting components and electrical equipment. Background Technology

[0002] Electrical appliances such as household or industrial fans commonly employ telescopic support rod structures to meet height adjustment needs in different usage scenarios. This structure allows for flexible adjustment of the support rod length via sliding connections or threaded adjustments, thereby regulating the overall height of the fan. However, during the extension and retraction of the support rod, the power supply cables connecting the fan motor and the power source (such as power cords and control cables) must also change length, easily leading to tangling, pulling, wear, or even breakage, severely impacting equipment safety and lifespan. Related technologies manage these cables using spring wire structures, integrating elastic metal wires or materials into the cable to achieve automatic retraction. However, this approach has drawbacks. After repeated stretching over a long period, the elasticity of the spring wire gradually diminishes, resulting in reduced retraction force and eventually problems such as the cable failing to retract completely, jamming, or detachment. Furthermore, for high-power fans, the power supply cables need to carry larger currents, requiring thicker wire diameters. Traditional spring wire structures are difficult to integrate with large-diameter wires, leading to manufacturing difficulties, complex assembly, and potential safety hazards. Utility Model Content

[0003] In view of this, the present invention provides a lifting component and electrical equipment to solve the problem that the elasticity of the spring wire decreases and the retraction failure occurs after long-term stretching, resulting in the inability of the wire to retract.

[0004] In a first aspect, this utility model provides a lifting assembly, comprising: Support base, including support tube; The take-up structure is rotatably disposed inside the support tube; A lifting rod is mounted on the support tube in a height-reducible manner; The cable passes through the lifting rod, and a portion of the cable is fixed to the take-up structure. A transmission structure is provided between the lifting rod and the take-up structure to convert the movement of the lifting rod into the rotation of the take-up structure. When the lifting rod rises, the take-up structure rotates in a first direction to release the line. When the lifting rod falls, the take-up structure rotates in a second direction to take the line into the take-up structure.

[0005] Beneficial Effects: By incorporating a take-up structure within the support tube and a transmission structure between the lifting rod and the take-up structure, the transmission structure converts the lifting motion of the lifting rod into rotation of the take-up structure. When the lifting rod rises, the take-up structure rotates in the first direction under the drive of the transmission structure, releasing the yarn wound on it to accommodate the rising lifting rod and prevent tension on the yarn. When the lifting rod descends, the take-up structure rotates in the second direction under the drive of the transmission structure, winding and storing the yarn on it, thus preventing tangling and knotting. This lifting assembly, by incorporating a take-up structure and a transmission structure between the lifting rod and the take-up structure, converts the lifting motion of the lifting rod into rotation of the take-up structure. Utilizing the lifting motion of the lifting rod to drive the rotation of the take-up structure achieves active winding and storage of the yarn, avoiding fatigue damage caused by long-term tension on the yarn and extending its service life. Compared to the use of spring yarn in related technologies, it avoids the problems of elastic decay and shrinkage failure, achieving stable yarn storage and a long service life.

[0006] In one optional embodiment, the take-up structure is provided with a wire groove and a winding position, and the wire is adapted to enter the winding position through the wire groove.

[0007] Beneficial effects: By setting the wire groove, the wire enters the winding position through the wire groove. The wire groove can guide the wire in an orderly manner, ensuring that the wire does not deviate, knot or be locally squeezed during the winding process, avoiding friction damage to the wire, effectively protecting the insulation layer of the wire, reducing the risk of short circuit, and making the wire neatly stored without affecting the rotation of the winding structure.

[0008] In one optional embodiment, the take-up structure includes a column, an annular upper plate at the top of the column, and an annular lower plate at the bottom of the column. The area between the annular upper plate and the annular lower plate constitutes the winding position, and the inlet of the wire groove is located on the annular upper plate.

[0009] Beneficial effects: The winding structure includes a column, an annular upper plate at the top of the column, and an annular lower plate at the bottom of the column. The area between the annular upper plate and the annular lower plate constitutes the winding position. Therefore, the winding position has a certain depth and can accommodate wires of any diameter. It is especially suitable for cables with large cross-sections and high current carrying capacity. It breaks through the limitations of traditional spring wires on wire diameter, improves process feasibility and electrical safety, and the annular upper plate and annular lower plate can limit the wire and prevent the wire from deviating during the winding process.

[0010] In one optional embodiment, the annular upper plate is provided with a first guide member and a second guide member. The first guide member has a first guide surface that extends downward and simultaneously extends circumferentially, and the second guide member has a second guide surface that extends in the same direction as the first guide surface. The area between the first guide surface and the second guide surface constitutes the wire groove.

[0011] Beneficial effects: The first guide member has a first guide surface that extends downward and simultaneously in the circumferential direction, and the second guide member has a second guide surface that extends in the same direction as the first guide surface. The area between the first guide surface and the second guide surface forms a wire groove. The wire groove has a certain length and can guide the wire in an orderly manner. When the winding structure rotates in the second direction, it ensures that the wire is wound around the outside of the column, ensuring that the wire does not deviate, knot, or be locally squeezed during the winding process, avoiding friction damage to the wire, effectively protecting the insulation layer of the wire, reducing the risk of short circuit, and making the wire neatly stored.

[0012] In one optional embodiment, the take-up structure is provided with a wire-passing hole, which is lower than the wire groove, and the wire passes through and is fixed to the wire-passing hole.

[0013] Beneficial effect: By setting a wire passage hole on the take-up structure, which is lower than the wire groove, the wire passes through and is fixed in the wire passage hole. Therefore, it can be ensured that the wire can be wound and stored on the column when the take-up structure rotates in the second direction.

[0014] In one optional embodiment, a wire-fixing structure is provided inside the wire hole, and the wire is fixed by the wire-fixing structure.

[0015] Beneficial effect: By providing a wire-fixing structure inside the wire hole, the wire is fixed by the wire-fixing structure, which can ensure that the wire will not slide inside the wire hole, thereby ensuring that the wire can be wound and stored on the column when the winding structure rotates in the second direction.

The lead screw includes a body, which is threadedly engaged with the lifting rod connector. The first end of the lead screw is rotatably engaged with the upper cover, and the second end of the lead screw is fixed to the take-up structure.

[0017] Beneficial effects: The top cover is fixed to the top of the support tube, so the top cover remains stationary with the support seat when the lifting rod is raised or lowered.

The main body of the lead screw is threadedly engaged with the lifting rod joint. The first end of the lead screw is rotatably engaged with the top cover, and the second end of the lead screw is fixed to the take-up structure. Therefore, when the lifting rod joint is raised or lowered by the lifting rod, the lead screw rotates and drives the take-up structure to rotate. Thus, when the lifting rod rises, the take-up structure rotates in the first direction, and the line wound on the take-up structure is released to adapt to the rise of the lifting rod and prevent the line from being pulled. When the lifting rod falls, the take-up structure rotates in the second direction, and the line is wound and stored on the take-up structure, avoiding problems such as tangling and knotting of the line.

[0018] In one optional embodiment, the lifting rod is provided with a first engaging portion, and the lifting rod connector is provided with a second engaging portion, wherein the first engaging portion and the second engaging portion are engaged.

[0019] Beneficial effects: By setting a first engaging part on the lifting rod and a second engaging part on the lifting rod joint, the first engaging part and the second engaging part are engaged to facilitate the fixed connection between the lifting rod and the lifting rod joint, which can improve assembly efficiency.

[0021] Beneficial effects: The lifting rod connector has a fixing hole, and the lifting rod is inserted into the fixing hole. Therefore, the lifting rod and the lifting rod connector have a large contact area. The second engaging part is located on the side wall of the fixing hole. When the lifting rod is inserted into the fixing hole and is in place, the first engaging part and the second engaging part engage, which can ensure a stable connection between the lifting rod and the lifting rod connector.

[0022] In one optional embodiment, from top to bottom, the fixing hole includes a first hole segment and a second hole segment, the inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, a mounting surface is formed between the first hole segment and the second hole segment, and the lifting rod is adapted to be supported on the mounting surface.

The first hole section and the second hole section form a mounting surface, which can be used to position the lifting rod.

[0024] In one optional embodiment, the upper cover is provided with one of a rotating groove and a first connector, and the first end of the lead screw is provided with the other of a rotating groove and a first connector, wherein the first connector is rotatably disposed in the rotating groove. And / or, the take-up structure is provided with one of a slot and a second connector, and the second end of the lead screw is provided with the other of a slot and a second connector, the second connector being fixed to the slot.

[0025] Beneficial effects: By providing one of a rotating groove and a first connector on the top cover, and the other of a rotating groove and a first connector on the first end of the lead screw, it is convenient to position and install the first end of the lead screw; by providing one of a slot and a second connector on the take-up structure, and the other of a slot and a second connector on the second end of the lead screw, it is convenient to position and install the second end of the lead screw.

[0026] In one optional embodiment, the take-up structure has a winding position with a diameter of d, the lead screw has a pitch of A, and the lifting rod has a descent or descent stroke of L. , where θ is the rotation angle of the lead screw.

[0027] Beneficial effect: It can ensure that when the lifting rod rises or falls by L, the winding structure releases or winds the corresponding length of line, ensuring no excess line.

[0028] In one optional embodiment, the inner wall of the support tube is provided with a support ring, and the take-up structure is rotatably disposed on the support ring.

[0029] Beneficial effects: By setting a support ring on the inner wall of the support tube, it is easy to position and install the take-up structure, and the support ring does not affect the direction of the line.

[0030] In one optional embodiment, the take-up structure has multiple winding positions, and the depth of the winding positions of each take-up structure is different.

[0031] Beneficial effects: Since the winding depth of each take-up structure is different, users can choose to replace the take-up structure with the corresponding depth according to the cable specifications, thereby improving the versatility of the equipment.

[0032] In one optional embodiment, the take-up structure is provided with a detection structure that can detect the rotation angle of the take-up structure. The lifting assembly also includes a control panel that is communicatively connected to the detection structure. The control panel can display the remaining cable length based on the detection data from the detection structure.

[0033] Beneficial effects: The control panel can display the remaining amount of the thread, allowing users to clearly see the degree of winding, thus improving user experience and safety.

[0034] Secondly, this utility model also provides an electrical device, comprising: The aforementioned lifting assembly.

[0035] Beneficial Effects: This electrical device, by incorporating a take-up structure within the support tube and a transmission structure between the lifting rod and the take-up structure, converts the lifting motion of the lifting rod into rotation of the take-up structure. When the lifting rod rises, the take-up structure rotates in the first direction under the drive of the transmission structure, releasing the cable wound on it to accommodate the rising lifting rod and prevent tension on the cable. When the lifting rod descends, the take-up structure rotates in the second direction under the drive of the transmission structure, winding and storing the cable on it, thus preventing tangling and knotting. This electrical device, by setting up a take-up structure and a transmission structure between the lifting rod and the take-up structure, converts the lifting motion of the lifting rod into rotation of the take-up structure. Utilizing the lifting motion of the lifting rod to drive the rotation of the take-up structure achieves active winding and storage of the cable, avoiding fatigue damage caused by long-term tension on the cable, extending its service life.

[0043] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0044] Electrical appliances such as household or industrial fans commonly employ telescopic support rod structures to meet height adjustment needs in different usage scenarios. This structure allows for flexible adjustment of the support rod length via sliding connections or threaded adjustments, thereby regulating the overall height of the fan. However, during the extension and retraction of the support rod, the power supply cables connecting the fan motor and the power source (such as power cords and control cables) must also change length, easily leading to tangling, pulling, wear, or even breakage, severely impacting equipment safety and lifespan. Related technologies manage these cables using spring wire structures, integrating elastic metal wires or materials into the cable to achieve automatic retraction. However, this approach has drawbacks. After repeated stretching over a long period, the elasticity of the spring wire gradually diminishes, resulting in reduced retraction force and eventually problems such as the cable failing to retract completely, jamming, or detachment. Furthermore, for high-power fans, the power supply cables need to carry larger currents, requiring thicker wire diameters. Traditional spring wire structures are difficult to integrate with large-diameter wires, leading to manufacturing difficulties, complex assembly, and potential safety hazards.

[0045] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a lifting assembly is provided, including a support base 1, a winding structure 2, a lifting rod 3, a cable body 4, and a transmission structure.

[0047] The support base 1 includes a support tube 101; a take-up structure 2 is rotatably disposed inside the support tube 101; a lifting rod 3 is vertically disposed within the support tube 101; a line 4 passes through the lifting rod 3, and a portion of the line 4 is fixed to the take-up structure 2; a transmission structure is disposed between the lifting rod 3 and the take-up structure 2, used to convert the movement of the lifting rod 3 into the rotation of the take-up structure 2. When the lifting rod 3 rises, the take-up structure 2 rotates in a first direction to release the line 4; when the lifting rod 3 falls, the take-up structure 2 rotates in a second direction to collect the line 4 into the take-up structure 2.

[0048] In this embodiment, by setting a take-up structure 2 inside the support tube 101 and setting a transmission structure between the lifting rod 3 and the take-up structure 2, the transmission structure can convert the lifting movement of the lifting rod 3 into the rotation of the take-up structure 2. When the lifting rod 3 rises, the take-up structure 2 rotates in the first direction under the drive of the transmission structure, and the line 4 wound on the take-up structure 2 is released to adapt to the rise of the lifting rod 3 and prevent the line 4 from being pulled. When the lifting rod 3 falls, the take-up structure 2 rotates in the second direction under the drive of the transmission structure, and the line 4 is wound and stored on the take-up structure 2, which can avoid problems such as the line 4 getting tangled or knotted. This lifting assembly, by setting up a take-up structure 2 and a transmission structure between the lifting rod 3 and the take-up structure 2, can convert the lifting movement of the lifting rod 3 into the rotation of the take-up structure 2. The lifting movement of the lifting rod 3 drives the rotation of the take-up structure 2, thereby achieving active winding and storage of the cable 4. This avoids fatigue damage caused by long-term tension on the cable 4, extends the service life of the cable 4, and avoids the problems of elastic decay and retraction failure in related technologies. It achieves the technical effect of stable cable storage and long service life.

[0049] In one specific embodiment, the support base 1 further includes a chassis 102, which is fixed below the support tube 101.

[0050] In one embodiment, such as Figure 4 As shown, the take-up structure 2 is provided with a wire groove 201 and a winding position 202, and the wire body 4 is adapted to enter the winding position 202 through the wire groove 201.

[0051] In this embodiment, by setting the wire groove 201, the wire 4 enters the winding position 202 through the wire groove 201. The wire groove 201 can guide the wire 4 in an orderly manner, ensuring that the wire 4 does not deviate, knot or be locally squeezed during the winding process, avoiding friction damage to the wire 4, effectively protecting the insulation layer of the wire 4, reducing the risk of short circuit, and making the wire 4 neatly stored without affecting the rotation of the take-up structure 2. In one embodiment, such as Figure 9 As shown, the take-up structure 2 includes a column 203, an annular upper plate 204 at the top of the column 203, and an annular lower plate 205 at the bottom of the column 203. The area between the annular upper plate 204 and the annular lower plate 205 constitutes the winding position 202. The entrance of the conductor groove 201 is located in the annular upper plate 204.

[0052] In this embodiment, the take-up structure 2 includes a column 203, an annular upper plate 204 at the top of the column 203, and an annular lower plate 205 at the bottom of the column 203. The area between the annular upper plate 204 and the annular lower plate 205 constitutes the winding position 202. Therefore, the winding position 202 has a certain depth and can accommodate wires 4 of any diameter. It is especially suitable for cables with large cross-sections and high current carrying capacity, breaking through the limitations of traditional spring wires on wire diameter, improving process feasibility and electrical safety. Furthermore, the annular upper plate 204 and the annular lower plate 205 can limit the wire 4 and prevent the wire 4 from deviating during the winding process.

[0053] In an alternative embodiment, the take-up structure 2 may consist only of a column 203, which is large at both ends and small in the middle, and the wire 4 may be wound and stored on the column 203.

[0054] In one embodiment, the annular upper plate 204 is provided with a first guide 206 and a second guide 207. The first guide 206 has a first guide surface 2061 that extends downward and simultaneously extends circumferentially. The second guide 207 has a second guide surface 2071 that extends in the same direction as the first guide surface 2061. The area between the first guide surface 2061 and the second guide surface 2071 forms a wire groove 201.

[0055] In this embodiment, the first guide member 206 has a first guide surface 2061 extending downward and simultaneously extending circumferentially, and the second guide member 207 has a second guide surface 2071 extending in the same direction as the first guide surface 2061. The area between the first guide surface 2061 and the second guide surface 2071 forms a wire groove 201. The wire groove 201 has a certain length and can guide the wire 4 in an orderly manner. When the take-up structure 2 rotates in the second direction, it ensures that the wire 4 is wound around the column 203, ensuring that the wire 4 does not deviate, knot, or be locally squeezed during the winding process, avoiding friction damage to the wire 4, effectively protecting the insulation layer of the wire 4, reducing the risk of short circuit, and making the wire 4 neatly stored.

[0056] In one embodiment, the take-up structure 2 is provided with a wire passage hole 208, which is lower than the wire groove 201, and the wire 4 passes through and is fixed in the wire passage hole 208.

[0057] In this embodiment, by providing a wire hole 208 on the take-up structure 2, with the wire hole 208 being lower than the wire groove 201, the wire 4 passes through and is fixed in the wire hole 208, thus ensuring that the wire 4 can be wound and stored on the column 203 when the take-up structure 2 rotates in the second direction.

[0058] In one embodiment, such as Figure 7 and Figure 8As shown, the column 203 has a hollow structure, and the wire hole 208 is provided on the column 203. The wire 4 passes through the wire hole 208 from the outside to the inside, enters the inside of the column 203, and exits from the bottom of the column 203.

[0059] Specifically, the support tube 101 is provided with a wire outlet hole 1012. The wire 4 passes through the wire outlet hole 208 from the outside to the inside, enters the inner side of the column 203, and exits from the bottom of the column 203. Then it extends out of the support tube 101 through the wire outlet hole 1012.

[0060] In an alternative embodiment, the wire hole 208 may be disposed on the annular lower plate 205.

[0061] In one embodiment, a wire fixing structure 209 is provided inside the wire hole 208, and the wire body 4 is fixed by the wire fixing structure 209.

[0062] In this embodiment, by providing a wire fixing structure 209 in the wire hole 208, the wire body 4 is fixed by the wire fixing structure 209, which can ensure that the wire body 4 will not slide in the wire hole 208, thereby ensuring that the wire body 4 can be wound and stored on the column 203 when the take-up structure 2 rotates in the second direction.

[0063] Specifically in one embodiment, such as Figure 9 As shown, the wire fixing structure 209 includes multiple cantilever rods 2091 evenly distributed. One end of the cantilever rod 2091 is connected to the wall of the wire passage hole 208, and the other end extends towards the center of the wire passage hole 208. The other end of the cantilever rod 2091 is provided with an arc rod 2092. There is a gap between two adjacent arc rods 2092. During installation, the cantilever rod 2091 can be deformed to a certain extent so that the wire 4 passes through the wire passage hole 208. After the position of the wire 4 is determined, the multiple arc rods 2092 clamp the wire 4 in the middle to ensure that the wire 4 will not slide in the wire passage hole 208.

[0064] In one embodiment, a top cover 5 is fixed to the top of the support tube 101. The top cover 5 has a sliding hole 501. The lifting rod 3 passes through the sliding hole 501 and can slide up and down relative to the sliding hole 501. The transmission structure includes a lifting rod connector 6 and a lead screw 7. The lifting rod connector 6 is fixedly connected to the lifting rod 3. The lead screw 7 includes a body 701, which is threadedly engaged with the lifting rod connector 6. The first end of the lead screw 7 is rotatably engaged with the top cover 5, and the second end of the lead screw 7 is fixed to the take-up structure 2.

[0065] In this embodiment, the top cover 5 is fixed to the top of the support tube 101. Therefore, when the lifting rod 3 is raised or lowered, the top cover 5 remains stationary with the support seat 1. Since the lifting rod joint 6 is fixedly connected to the lifting rod 3, the lifting rod 3 raises or lowers together with the lifting rod joint 6 when it is raised or lowered. The main body 701 of the lead screw 7 is threadedly engaged with the lifting rod joint 6. The first end of the lead screw 7 is rotatably engaged with the top cover 5, and the second end of the lead screw 7 is fixed to the take-up structure 2. Therefore, when the lifting rod joint 6 is raised or lowered under the action of the lifting rod 3, the lead screw 7 rotates and drives the take-up structure 2 to rotate. This allows the take-up structure 2 to rotate in the first direction when the lifting rod 3 rises, releasing the line 4 wound on the take-up structure 2 to accommodate the rise of the lifting rod 3 and prevent the line 4 from being pulled. When the lifting rod 3 falls, the take-up structure 2 rotates in the second direction, and the line 4 is wound and stored on the take-up structure 2, avoiding problems such as tangling or knotting of the line 4.

[0066] In one specific embodiment, the first direction is counterclockwise and the second direction is clockwise. When the lifting rod 3 rises, the take-up structure 2 rotates counterclockwise to release the line 4. When the lifting rod 3 falls, the take-up structure 2 rotates clockwise to wind up and take in the line 4.

[0092] In one specific embodiment, the detection structure is an encoder.

[0093] In this embodiment, the lifting assembly is assembled as follows: First, the cable 4 passes through the central cavity of the lifting rod 3 from top to bottom. Then, the upper cover 5 is removed, and the lifting rod 3 is aligned with the sliding hole 501 of the upper cover 5. The cable 4 and the lifting rod 3 are then passed through. Next, the lifting rod connector 6 is removed, and the lifting rod 3 is aligned with the fixing hole 602 of the lifting rod connector 6.

Finally, the take-up structure 2 is removed, and the slot 210 of the take-up structure 2 is aligned with the second connector 703 of the lead screw 7, and the second connector 703 is inserted into the slot. After installation in the slot 210, use screws to fix it in place, completing the complete fixation of the take-up structure 2 and the lead screw 7. Then, slightly tighten the cable 4 and arrange the cable in the order of the wire groove 201-the cable hole 208. The cable 4 passes through the cable hole 208 and the cable fixing structure 209 to ensure that there is no slippage. Then, take the support tube 101 of the support base 1, pass the cable 4 out of the cable outlet hole 1012, and then put the support tube 101 into the take-up structure 2-the lead screw 7-the lifting rod connector 6 in sequence until the lower surface of the take-up structure 2 abuts against the support ring 1011 of the support rod. Then, put the top cover 5 into the support tube 101. The entire structure, including the cable routing, is contained in the cavity formed by the support tube 101 and the top cover 5. The cable 4 is basically realized in the cavity of the winding groove and the column 203. Finally, install the chassis 102, thus completing all the assembly.

[0094] According to an embodiment of the present invention, another aspect provides an electrical device, including: the lifting assembly provided in the above embodiment.

[0095] This electrical device, by setting a take-up structure 2 inside the support tube 101 and setting a transmission structure between the lifting rod 3 and the take-up structure 2, can convert the lifting movement of the lifting rod 3 into the rotation of the take-up structure 2. When the lifting rod 3 rises, the take-up structure 2 rotates in the first direction under the drive of the transmission structure, and the wire 4 wound on the take-up structure 2 is released to adapt to the rise of the lifting rod 3 and prevent the wire 4 from being pulled. When the lifting rod 3 falls, the take-up structure 2 rotates in the second direction under the drive of the transmission structure, and the wire 4 is wound and stored on the take-up structure 2, which can avoid problems such as the wire 4 getting tangled or knotted. This electrical device, by setting up a take-up structure 2 and a transmission structure between the lifting rod 3 and the take-up structure 2, can convert the lifting movement of the lifting rod 3 into the rotation of the take-up structure 2. The lifting movement of the lifting rod 3 drives the rotation of the take-up structure 2, thereby achieving active winding and storage of the cable 4. This avoids fatigue damage caused by long-term tension on the cable 4, extends the service life of the cable 4, and avoids the problems of elastic decay and shrinkage failure in related technologies. It achieves the technical effect of stable cable storage and long service life.

[0096] In one embodiment, the electrical device is a fan or a heater.

[0097] Specifically, the fan includes a fan head 8 and a rotating bracket 9. The top of the support rod is connected to the rotating bracket 9, and the fan head 8 is rotatably mounted on the rotating bracket 9.
