Description

Technical Field

[0001] This utility model relates to the field of clutch technology, and in particular to a clutch for manually switching to electric operation. Background Technology

[0002] A patent titled "An Electric Cable Reel" has been published in the Chinese Patent Database. The authorization announcement number is CN218909476U, and the authorization announcement date is April 25, 2023. The patent specification for this electric cable reel discloses that: a side plate 4 is fixed to the front side of the mounting frame body 1 near the bottom edge; a motor 5 is fixed to the top of the side plate 4 near one edge; a clutch 6 is fixed to the top of the side plate 4 near the other edge; the output end of the motor 5 is fixed to the input end of the clutch 6; and a drive sprocket 13 is fixed to the output end of the clutch 6.

[0003] Its drawback is that the clutch can only connect and disconnect power, which means that the cable reel can only be driven by an electric motor. This type of electric cable reel is not suitable for scenarios that require manual rotation of the cable reel, such as scenarios without power, motor failure scenarios, or scenarios that require fine adjustments (such as fine-tuning cable tension). Utility Model Content

[0004] This application provides a clutch with dual power inputs. By improving the clutch structure, the clutch can be connected to electric and manual power respectively, thereby improving the ease of use of the clutch and expanding the application scenarios of this clutch product.

[0005] The first aspect of this application provides a clutch with dual power inputs, comprising:

[0006] case;

[0007] The first input shaft is rotatably connected to the housing;

[0008] The active component is slidably disposed on the first input axis;

[0009] The output shaft is rotatably connected to the housing;

[0010] The driven member is connected to the output shaft and is used to engage or disengage with the driving member;

[0011] An elastic element is disposed between the first input shaft and the driving element, and is used to drive the driving element to engage with the driven element;

[0012] An adjustment mechanism, connected to the housing, is used to control the engagement or disengagement of the driving member and the driven member;

[0013] The second input shaft is rotatably connected to the housing;

[0014] A transmission mechanism is disposed between the output shaft and the second input shaft.

[0015] The beneficial effects of the above embodiments are as follows: when the driving member and the driven member are engaged, the output shaft is driven to rotate through the first input shaft; when the driving member and the driven member are separated, the output shaft is driven to rotate through the second input shaft, so that the clutch has two power input sources. The first input shaft is driven to rotate by a motor and the second input shaft is driven to rotate by manual means, so that electric power and manual power are output through the clutch respectively.

[0016] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0017] In one embodiment of this application: the driving component is equipped with a slider, and the first input shaft is equipped with a groove, with the slider slidably inserted into the groove. The beneficial effect of this step is that the sliding connection between the driving component and the first input shaft is achieved through the cooperation of the slider and the groove.

[0018] In one embodiment of this application: the driving member is configured with a driving protrusion, and the driven member is configured with a driven hole. When the driving protrusion is inserted into the driven hole, the driving member and the driven member engage. The beneficial effect of this step is that the power of the first input shaft is transmitted to the output shaft through the engagement of the protrusion and the hole.

[0019] In one embodiment of this application: the adjusting mechanism includes a clutch shaft and a rocker arm. The clutch shaft and the rocker arm are rotatably connected to the housing. The clutch shaft has a connecting portion and a separating portion. One end of the rocker arm is connected to the driving member, and the other end is connected to the clutch shaft. When the rocker arm contacts the connecting portion, the driving member and the driven member are engaged. When the rocker arm contacts the separating portion, the driving member and the driven member are separated. The beneficial effect of this step is that by rotating the clutch shaft, the rotation of the rocker arm is controlled, thereby realizing the function of engaging or disengaging the driving member and the driven member.

[0020] In one embodiment of this application, the adjusting mechanism further includes a rotating wheel, which is rotatably connected to the rocker arm and contacts the driving member. The beneficial effect of this step is that the rotating wheel reduces friction at the contact points, thereby improving the smoothness of the clutch shaft and rocker arm rotation.

[0021] In one embodiment of this application, the adjusting mechanism further includes a first limiting member, a second limiting member, and a swing member. The swing member is connected to the clutch shaft. The first limiting member and the second limiting member are both connected to the housing. The first limiting member is disposed on one side of the swing member, and the second limiting member is disposed on the other side of the swing member. The first limiting member and the second limiting member are used to limit the swing range of the swing member. The beneficial effect of this step is that the rotation angle of the clutch shaft is limited by the cooperation of the first limiting member, the second limiting member, and the swing member, thereby improving the ease of use of the clutch.

[0022] In one embodiment of this application, the adjusting mechanism further includes a turntable, a switching shaft, and a transmission assembly. The switching shaft is rotatably connected to the housing, the turntable is mounted on the switching shaft, and the transmission assembly is disposed between the clutch shaft and the switching shaft. The advantage of this step is that it facilitates the operator in driving the clutch shaft to rotate. Attached Figure Description

[0031] Example

[0032] like Figure 1-4 As shown, a clutch with dual power inputs includes: a housing 1, a first input shaft 2, a driving member 3, an output shaft 4, a driven member 5, an elastic member 6, an adjusting mechanism 7, a second input shaft 8, and a transmission mechanism 9. The first input shaft 2 is rotatably connected to the housing 1. The driving member 3 is slidably disposed on the first input shaft 2. The output shaft 4 is rotatably connected to the housing 1. The driven member 5 is connected to the output shaft 4 and is used to engage or disengage with the driving member 3. The elastic member 6 is disposed between the first input shaft 2 and the driving member 3 and is used to drive the driving member 3 to engage with the driven member 5. The adjusting mechanism 7 is connected to the housing 1 and is used to control the engagement or disengagement of the driving member 3 and the driven member 5. The second input shaft 8 is rotatably connected to the housing 1. The transmission mechanism 9 is disposed between the output shaft 4 and the second input shaft 8.

[0033] In some embodiments of this application, such as Figure 2 As shown, housing 1 has a square structure. The bottom of housing 1 is a connecting plate, which is connected to the product using this type of clutch by bolts. The top cover of housing 1 is hidden in the diagram. A partition is set inside housing 1, which divides the interior of housing 1 into region A and region B. The first input shaft 2 and the adjustment mechanism 7 are set on one side of region A, and the second input shaft 8 and the transmission mechanism 9 are set on one side of region B. The output shaft 4 passes through region B. The partition separates housing 1, making the internal parts of the clutch more rationally arranged.

[0034] In some embodiments of this application, such as Figure 2As shown, the first input shaft 2 is connected to the housing 1 through a bearing seat. One end of the first input shaft 2 is located outside the housing 1 and is used to connect to the motor main shaft through a coupling. The other end of the first input shaft 2 extends into area A. The output shaft 4 is connected to the housing 1 through a bearing seat. The output shaft 4 and the first input shaft 2 are arranged coaxially. The driving member 3 and the driven member 5 are both located in area A.

[0035] In some embodiments of this application, such as Figure 4 As shown, the driving member 3 is equipped with a slider 301, and the first input shaft 2 is equipped with a groove 201. The slider 301 is slidably inserted into the groove 201. Specifically, both the driving member 3 and the driven member 5 are disc-shaped structures. The driving member 3 has a through hole along its axis, and the inner wall of the through hole of the driving member 3 is provided with sliders 301 evenly distributed around the inner wall of the through hole. The outer periphery of the first input shaft 2 is provided with a groove 201 parallel to the axis corresponding to the slider 301. The driving member 3 is slidably fitted onto the first input shaft 2 through the through hole and is slidably disposed on the first input shaft 2 along a straight line by the slider 301. The driven member 5 is fixedly connected to the end of the output shaft 4 located in region A. The sliding connection between the driving member 3 and the first input shaft 2 is realized by the cooperation of the slider 301 and the groove 201.

[0036] In some embodiments of this application, such as Figure 1 As shown, the elastic element 6 is a cylindrical compression spring (referred to as compression spring). The first input shaft 2 is equipped with a positioning plate. The compression spring is fitted onto the first input shaft 2 and is located between the positioning plate and the driving element 3. The compression spring applies pressure to the driving element 3, so that the driving element 3 has the power to move toward the driven element 5.

[0037] In some embodiments of this application, such as Figure 4 As shown, the driving member 3 is equipped with a driving protrusion 302, and the driven member 5 is equipped with a driven hole 501. When the driving protrusion 302 is inserted into the driven hole 501, the driving member 3 and the driven member 5 are engaged. Specifically, the driving protrusion 302 is a cylindrical structure, and the driving protrusions 302 are evenly distributed on the same circumference with the axis of the first input shaft 2 as the center line. The driven hole 501 can be a through hole or a blind hole. The driven hole 501 is an arc hole, and each driving protrusion 302 is equipped with a driven hole 501. The arc length of the arc hole is much larger than the outer diameter of the driving protrusion 302, which facilitates the insertion of the driving protrusion 302 into the driven hole 501.

[0038] In some embodiments of this application, such as Figure 4As shown, the adjustment mechanism 7 includes a clutch shaft 701 and a rocker arm 702. The clutch shaft 701 and the rocker arm 702 are rotatably connected to the housing 1. The clutch shaft 701 has a connecting part 703 and a separating part 704. One end of the rocker arm 702 is connected to the driving member 3 and the other end is connected to the clutch shaft 701. When the rocker arm 702 contacts the connecting part 703, the driving member 3 engages with the driven member 5. When the rocker arm 702 contacts the separating part 704, the driving member 3 separates from the driven member 5. Specifically, the clutch shaft 701 is located in region A, above the area between the driving member 3 and the driven member 5. The clutch shaft 701 is longitudinally arranged and perpendicular to the first input shaft 2. There are two rocker arms 702 symmetrically arranged on both sides of the first input shaft 2. The rocker arms 702 are vertically arranged and hinged to the housing 1 in the middle. The upper end of the rocker arm 702 has a separation part 704 and a connection part 703. The end of the clutch shaft 701 is a cylindrical structure with a notch structure. The recessed plane formed by the notch structure at the end of the clutch shaft 701 is the connection part 703. The outer arc surface adjacent to the connection part 703 at the end of the clutch shaft 701 is the separation part 704. When the connection part 703 contacts the rocker arm 702, since the connection part 703 is the recessed structure at the end of the clutch shaft 701, the rocker arm 702 and the clutch shaft 702 are separated. A gap is created between the clutch shafts 701. The other end of the rocker arm 702 rotates around its hinge point with the housing 1 under the push of the driving member 3, so that the rocker arm 702 contacts and positions itself again with the clutch shaft 701 (joint part 703). During this process, the drive protrusion 302 is inserted into the driven hole 501 to realize the engagement of the driving member 3 and the driven member 5. The clutch shaft 701 is rotated until the separation part 704 contacts the rocker arm 702. During this process, as the thickness of the clutch shaft 701 at the contact part gradually increases, it gradually pushes the rocker arm 702 to rotate, so that the other end of the rocker arm 702 pushes the driving member 3 to compress the elastic member 6, and the driving member 3 separates from the driven member 5. The external force at the contact part of the rocker arm 702 and the clutch shaft 701 always points towards the axis of the clutch shaft 701. Therefore, when the driving member 3 separates from the driven member 5, the rocker arm 702 will not push the clutch shaft 701 to rotate in the opposite direction.

[0039] In some embodiments of this application, such as Figure 4 As shown, the adjustment mechanism 7 further includes a rotating wheel 705, which is rotatably connected to the rocker arm 702 and contacts the driving member 3. Specifically, the rotating wheel 705 is rotatably connected to the end of the rocker arm 702 driven by the driving member 3. When the driving member 3 pushes the rocker arm 702 to rotate, the end of the rocker arm 702 will undergo a certain displacement relative to the driving member 3 during rotation. This displacement is achieved by the rotation of the rotating wheel 705, thereby reducing the friction at the contact points and improving the smoothness of the clutch shaft 701 rotation.

[0040] In some embodiments of this application, such as Figure 3 As shown, the adjusting mechanism 7 further includes: a first limiting member 706, a second limiting member 707, and a swing member 708. The first limiting member 706, the second limiting member 707, and the swing member 708 are all cylindrical structures. The swing member 708 is radially connected to the clutch shaft 701 along the clutch shaft 701. The first limiting member 706 and the second limiting member 707 are both connected to the housing 1. The first limiting member 706 is disposed on one side of the swing member 708, and the second limiting member 707 is disposed on the other side of the swing member 708. The first limiting member 706 and the second limiting member 707 are used to limit the swing range of the swing member 708. Through the cooperation of the first limiting member 706, the second limiting member 707, and the swing member 708, the rotation angle of the clutch shaft 701 is limited, thereby improving the ease of use of the clutch.

[0041] In some embodiments of this application, such as Figure 1 As shown, the adjustment mechanism 7 further includes: a turntable 709, a switching shaft 710, and a transmission assembly 711. The switching shaft 710 is rotatably connected to the housing 1, the turntable 709 is mounted on the switching shaft 710, and the transmission assembly 711 is disposed between the clutch shaft 701 and the switching shaft 710. Specifically, the transmission assembly 711 includes: a first gear and a second gear. The first gear is mounted on the switching shaft 710, and the second gear is mounted on the clutch shaft 701. The first gear and the second gear mesh. By manually rotating the turntable 709, the transmission assembly 711 drives the clutch shaft 701 to rotate.

[0042] In some embodiments of this application, such as Figure 2 As shown, the transmission mechanism 9 includes a third gear and a fourth gear. Both the third gear and the fourth gear are located in region B. The third gear is mounted on the output shaft 4, and the fourth gear is mounted on the second input shaft 8. Both the third gear and the fourth gear are bevel gears and mesh with each other. The end of the second input shaft 8 located outside the housing 1 has a square structure and is used to insert a connecting rod with a square hole. When the output shaft 4 is disconnected from the first input shaft 2, the connecting rod is manually driven to rotate, thereby driving the second input shaft 8 to rotate.

[0043] In operation, this clutch uses a first input shaft 2 to input electric drive force and a second input shaft 8 to input manual drive force. The operator rotates the turntable 709 as needed. When the lever 702 contacts the engagement part 703, the driving member 3 engages with the driven member 5 under the push of the elastic member 6, thus transmitting power to the output shaft 4 via the first input shaft 2. When the lever 702 contacts the disengagement part 704, the driving member 3 disengages from the driven member 5 under the push of the lever 702, thus transmitting power to the output shaft 4 via the second input shaft 8. Therefore, it achieves the function of separately outputting electric and manual power through the clutch.
