Detailed Implementation

[0024] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model 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. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] like Figures 1 to 4As shown, this utility model provides a dual-output device, which includes a housing 10, an inner housing 20 detachably installed inside the housing 10, a power mechanism 30 installed in the inner housing 20, and a power output mechanism 50. Both the housing 10 and the inner housing 20 are shell structures. The housing 10 is used to connect a track device, a rope winding device, or other actuators, while the inner housing 20 is used to install and fix the power mechanism 30 and the power output mechanism 50, etc., transmission structures.

[0026] The power output mechanism 50 includes a power unit 56, an input shaft 53 with its central axis aligned, a first output component 54, and a second output component 55. The input shaft 53 is drive-connected to the power mechanism 30, and both the first output component 54 and the second output component 55 are rotatably connected to the inner housing 20. The first output component 54 and the second output component 55 serve as two power output structures of the power switching output mechanism. The input shaft 53 is connected to the power mechanism 30, which serves as a single power source for the dual-output device. By switching the power, one of the first output component 54 and the second output component 55 can be output.

[0027] The input shaft 53 passes through at least the first output member 54. A switching member 52 is drivenly connected to the input shaft 53. The power unit 56 drives the switching member 52 to move along the axial direction of the input shaft 53, so that the switching member 52 engages with the first output member 54 or the second output member 55. The switching member 52 moves under the drive control of the power unit 56. The input shaft 53, the first output member 54, and the second output member 55 are coaxially arranged. The switching member 52 can move along the axial direction of the input shaft 53 to perform power output position switching.

[0028] For example, when the switching element 52 moves to engage with the first output element 54, the input shaft 53, the switching element 52, and the first output element 54 form a power transmission path, and the second output element 55 is in a non-powered state. When the switching element 52 moves to engage with the second output element 55, the input shaft 53, the switching element 52, and the second output element 55 form a power transmission path, and the first output element 54 is in a non-powered state.

[0029] The power switching output mechanism uses a single input shaft 53 to input driving force, and the power unit 56 drives the switching element 52 to move. By controlling the meshing transmission position of the switching element 52, the input shaft 53 drives the first output element 54 or the second output element 55 to switch the power output, thereby optimizing the power output path and reducing costs.

[0030] The inner shell 20 has multiple partitions, and both the first output component 54 and the second output component 55 are rotatably connected to the partitions. The first output component 54 is partially inserted into one of the partitions, and the two are rotatably connected. The first output component 54 and the partition can be directly connected; alternatively, the first output component 54 and the partition can be connected via bearings. The second output component 55 is rotatably mounted on another partition and is positioned opposite to the first output component 54. The input shaft 53 passes through both the first output component 54 and the second output component 55.

[0031] The switching element 52 slides on the input shaft 53 and is located inside the inner housing 20. The switching element 52 moves between the first output element 54 and the second output element 55 and engages with them accordingly. During the engagement process, the first output element 54 and the second output element 55 maintain a stable engagement position.

[0032] The power unit 56 drives the switching member 52 to slide, thereby adjusting the engagement position of the switching member 52. The power unit 56 includes a motor 562 and a screw 561 connected to the output end of the motor 562. A moving member 51 is slidably connected to the upper limit of the inner shell 20. The inner shell 20 prevents the moving member 51 from deflecting, maintains linear sliding, and improves sliding smoothness. Optionally, the inner shell 20 forms a switching cavity, with the two sides of the moving member 51 slidingly abutting against the cavity wall, and the switching member 52 moving within the switching cavity.

[0033] Preferably, the movable component 51 includes a movable wall and sliding walls distributed on both sides of the movable wall, forming an approximately "I" or "U" shaped structure. The sliding walls slide against the switching cavity, increasing the contact area between the movable component 51 and the switching cavity.

[0034] The moving part 51 is movably connected to the switching part 52, wherein the moving part 51 performs linear movement, and at least the meshing transmission part of the switching part 52 can rotate relative to the moving part 51.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment, the switching member 52 has an annular groove 521, and at least a portion of the moving member 51 is located within the annular groove 521. The annular groove 521 is a circular groove structure, which can be formed by a recess in the surface of the switching member 52; or, the annular groove 521 is a space formed by two spaced-apart protruding ribs on the surface of the switching member 52. At least a portion of the moving member 51 is located within the annular groove 521, and during the movement of the moving member 51, it abuts against the corresponding side wall of the annular groove 521, thereby driving the switching member 52 to move.

[0036] Motor 562 is mounted on inner housing 20, and screw 561 is rotatably connected to inner housing 20 and connected to the output end of motor 562. Screw 561 and moving part 51 are helically connected. When motor 562 drives screw 561 to rotate, moving part 51 moves back and forth linearly along screw 561. Preferably, the center line of screw 561 is parallel to input shaft 53.

[0037] The sliding wall is provided with a threaded hole, and the screw 561 is screwed into the threaded hole. The switching element 52 and the moving wall are rotatably connected to drive the switching element 52 to move.

[0038] The switching transmission method of the switching element 52: One end of the switching element 52 is engaged with the first output element 54. The first output element 54 has a concave transmission groove on the side facing the switching element 52. The transmission groove can be a spline groove or a square hole groove. A spline shaft is formed by protruding from the end of the switching element 52 facing the first output element 54. The spline shaft and the transmission groove are inserted and engaged to enable the switching element 52 and the transmission groove to be engaged and transmitted, so that the power of the input shaft 53 can be transmitted to the first output element 54 through the switching element 52.

[0039] In one embodiment, the first output member 54 is a bevel gear, and the power output mechanism 50 includes a first power end 11 that meshes with the first output member 54, the first power end 11 extending through the wall of the outer casing 10. The first output member 54 is a bevel gear, and a second bevel gear can also be rotatably mounted on the inner casing 20. The first output member 54 and the second bevel gear engage in bevel gear meshing transmission, and the rotation center of the first output member 54 intersects with the rotation center of the second bevel gear. The portion of the second bevel gear extending through the outer casing 10 constitutes the first power end 11.

[0040] Preferably, the first output member 54 and the second bevel gear have a small rotational gap during meshing. During the process of the switching member 52 being inserted into the first output member 54, the first output member 54 can be finely rotated to form an aligned connection.

[0041] The other end of the switching component 52 is engaged with the second output component 55. The switching component 52 has a spline hole on the side facing the second output component 55, and the spline hole communicates with the through hole. The spline hole is recessed from the end of the switching component 52 and is coaxial with the through hole. The second output component 55 and the spline hole are inserted and engaged for transmission connection.

[0042] In this embodiment, the switching component 52 and the second output component 55 are directly connected for transmission, which can form a direct-drive transmission.

[0043] In one embodiment, the second output member 55 has a spline groove at one end facing the input shaft 53. A connector 553 is engaged and slidably connected within the spline groove, and a compression spring 552 is provided between the connector 553 and the bottom wall of the spline groove. The connector 553 and the spline groove are slidably connected, and the compression spring 552 can provide the elastic preload required for the connector 553 to extend and retract.

[0044] The connector 553 extends elastically under the compression force of the spring 552. When the spline of the connector 553 and the spline hole of the switching piece 52 coincide, they are inserted into each other. When the spline of the connector 553 and the spline hole of the switching piece 52 do not coincide, the connector 553 and the switching piece 52 experience a slight impact. The connector 553 then overcomes the elastic force and compresses. The chamfered part of the spline hole presses against the connector 553 and rotates until they are aligned. The connector 553 then inserts into the spline hole, maintaining smooth docking.

[0045] The connector 553 is slidably connected to the second output member 55, and the second output member 55 limits the sliding range of the connector 553. The second output member 55 has an oblong hole, and a positioning pin 551 is fixedly connected to the connector 553, passing through the oblong hole. The oblong hole intersects and communicates with the spline groove. The oblong hole is an elongated hole structure to limit the maximum compression and extension of the connector 553 to the spline groove and the maximum length extending out of the second output member 55.

[0046] like Figures 3 to 5 As shown, the positioning pin 551 is inserted into the fixing connector 553 and confined in the waist-shaped hole, and can slide within a preset range without disengaging from the second output member 55.

[0047] In one embodiment, at least one stage planetary reduction gear 41 and a brake assembly 40 are coaxially mounted on a brake housing 43. A second output component 55 is connected to at least one stage planetary reduction gear 41 for power input reduction adjustment. The brake assembly 40 includes an input component 44, which is connected to the planetary gears of the final stage planetary reduction gear 41. The brake housing 43 and the inner housing 20 are assembled and connected.

[0048] The input component 44 serves as the power input point for connecting the brake assembly 40. At the same time, the planetary gears are rotatably mounted on the input component 44, forming the output part of the final stage planetary reduction gear 41. That is, the input component 44 integrates the brake assembly 40 and the final stage planetary reduction gear 41, reducing the number of transmission connection points while enabling each part to function independently, greatly reducing the size of the device and simplifying the structure.

[0049] Preferably, the brake assembly 40 further includes an output member 42, which is used to connect to the actuator, thereby enabling the brake assembly 40 to brake the actuator. The output member 42, as the second power end 12 of the dual-output device, can be connected to the actuator to achieve power output.

[0050] In one embodiment, the planetary reduction gear 41 includes an internal gear groove 431 formed within a brake seat 43. The internal gear groove 431 and the brake seat 43 are integrally formed, and the planetary gears of the planetary reduction gear 41 are meshed with the internal gear groove 431. The brake seat 43 forms part of the planetary reduction gear 41, and the planetary reduction gear 41 is assembled to the brake seat 43, reducing the number of components in the planetary reduction gear 41.

[0051] Furthermore, a positioning cavity 432 communicating with the internal tooth groove 431 is formed within the brake seat 43. The internal tooth groove 431 and the positioning cavity 432 are arranged side by side, and the positioning cavity 432 is recessed from one end of the brake seat 43. The positioning cavity 432 and the internal tooth groove 431 are located in the same communicating space within the brake seat 43. The brake assembly 40 is installed in the positioning cavity 432, and the brake assembly 40 and the planetary reduction gear 41 are easily assembled and connected.

[0052] The brake housing 45 separates the movable part of the brake assembly 40 from the brake seat 43. Simultaneously, the planetary gears mesh with the internal gear groove 431 to form the brake assembly 40. The input member 44 extends into the brake housing 45, and a speed reduction section is formed between the brake housing 45 and the input member 44. The brake housing 45 is inserted into the positioning cavity 432 and surrounds the input member 44, allowing the input member 44 to rotate relative to the brake housing 45.

[0053] The deceleration unit connects the input component 44 and the brake housing 45. The brake assembly 40 also includes an output component 42 and rollers 46. The input component 44 has a deceleration chamber with multiple slots on its wall and multiple protrusions on its inner side, with the slots and protrusions alternating. The outer peripheral wall of the output component 42 has alternating deceleration planes and moving grooves; preferably, three deceleration planes are provided, with a moving groove between every two adjacent deceleration planes.

[0054] The output component 42 is inserted into the reduction chamber, and the protrusion extends into the corresponding moving groove. The roller 46 is located in the space formed by the groove opening, the reduction plane, and the inner wall of the brake housing 45. The working principle of the brake assembly 40 can be found in CN222654968U, and will not be repeated here. The difference is that the input component 44, as part of the planetary reduction group 41, constitutes the power input part, and the output component 42 is used to connect the actuator. The planetary reduction group 41 can first reduce speed, and then brake the actuator through the brake assembly 40.

[0055] like Figure 2 , Figure 3 and Figure 6 As shown, in the above embodiment, the power mechanism 30 includes a transmission component 32 connected to the motor 31, the motor 31 being a power source, and preferably, the motor 31 is a brushless motor 31.

[0056] The transmission assembly 32 is used to adjust the output parameters of the motor 31, particularly the output torque and speed. The transmission assembly 32 includes a first planetary gear set 321 and a second planetary gear set 322 that are connected in a transmission manner. The first planetary gear set 321 includes a first internal gear sleeve 3211, and the second planetary gear set 322 includes a second internal gear sleeve 3221. The first internal gear sleeve 3211 and the second internal gear sleeve 3221 are detachably connected and form a transmission cavity. The transmission assembly 32 is installed in the inner housing 20 and connected to the input shaft 53.

[0057] The planet gears of the first planetary gear set 321 are meshed with the first tooth groove 3214. Similarly, the second planetary gear set 322 includes a second internal tooth sleeve 3221, which is provided with a second tooth groove 3226. The planet gears of the second planetary gear set 322 are meshed with the second tooth groove 3226.

[0058] The first planetary gear set 321 is connected to the motor 31, wherein the motor 31 is connected to the sun gear of the first planetary gear set 321, and the output part of the first planetary gear set 321 is connected to the sun gear of the second planetary gear set 322; or, the output part of the first planetary gear set 321 is configured with a toothed structure to form the sun gear of the second planetary gear set 322. The first planetary gear set 321 and the second planetary gear set 322 are a two-stage reduction transmission, which can reduce the speed and increase the torque.

[0059] The first inner gear sleeve 3211 and the second inner gear sleeve 3221 are detachably connected to form a housing portion, and the internal spaces of the first inner gear sleeve 3211 and the second inner gear sleeve 3221 form a transmission cavity. By disassembling and assembling the first inner gear sleeve 3211 and the second inner gear sleeve 3221, the first planetary gear set 321 and the second planetary gear set 322 can be disassembled and assembled.

[0060] In one embodiment, a positioning hole is formed on the first inner gear sleeve 3211, and a threaded hole corresponding to the positioning hole is formed on the motor 31. A fastener passes through the positioning hole and connects to the threaded hole, thereby connecting the first inner gear sleeve 3211 and the motor 31, shortening the length between the motor 31 and the transmission assembly 32, and improving structural compactness. After the first inner gear sleeve 3211 and the second inner gear sleeve 3221 are assembled, the connecting end of the fastener is located inside the transmission assembly 32.

[0061] In one embodiment, the first inner gear sleeve 3211 has a protruding insertion rib 3216 at its end, and the second inner gear sleeve 3221 has a recessed insertion groove 3222 at its end. The insertion rib 3216 and the insertion groove 3222 are engaged to assemble the first inner gear sleeve 3211 and the second inner gear sleeve 3221 into a single unit, forming a transmission cavity. When the insertion rib 3216 and the insertion groove 3222 are in place, the first planetary gear set 321 and the second planetary gear set 322 are connected in a transmission manner.

[0062] Preferably, the insertion parts of the insertion protrusion 3216 and the insertion groove 3222 are provided with complementary matching limiting protrusion 3215 and limiting groove 3223.

[0063] Specifically, the first inner toothed sleeve 3211 includes at least one limiting protrusion 3215 radially protruding from the self-inserting rib 3216, and the second inner toothed sleeve 3221 includes a limiting groove 3223 recessed in the inner wall of the self-inserting groove 3222. The self-inserting rib 3216 and the self-inserting groove 3222 are inserted into each other, and the limiting protrusion 3215 is inserted into the limiting groove 3223 to form a complementary fit, which can restrict circumferential rotation, improve the insertion positioning accuracy, and make the insertion direction controllable.

[0064] The transmission assembly 32 is mounted on the inner housing 20, and at least one of the first inner gear sleeve 3211 and the second inner gear sleeve 3221 is locked to the inner housing 20 by fasteners to form a fixed installation. Preferably, the inner housing 20 is provided with a mounting groove, and the second inner gear sleeve 3221 is mounted in the mounting groove.

[0065] The first inner gear sleeve 3211 has a locking hole, and the second inner gear sleeve 3221 has a clearance notch corresponding to the locking hole. A locking screw passes through the mounting hole on the inner housing 20, then through the clearance notch, and locks into the locking hole to secure the first inner gear sleeve 3211 and the inner housing 20. The first inner gear sleeve 3211 defines the position of the second inner gear sleeve 3221 within the mounting groove, thereby fixing the mounting position of the transmission assembly 32 and the inner housing 20.

[0066] The clearance notch is a notch located at the end of the second inner toothed sleeve 3221 to reduce the difficulty of aligning the locking screw with the locking hole and improve assembly convenience.

[0067] In one embodiment, the first planetary gear set 321 and the first internal gear sleeve 3211 constitute a planetary reduction mechanism. Preferably, the first internal gear sleeve 3211 is provided with a first tooth groove 3214, and the groove wall of the first tooth groove 3214 is configured with helical teeth. The first planetary gear set 321 includes a first planet carrier, at least one first planetary gear 3213 mounted on the first planet carrier, and a first gear 3212. The first tooth groove 3214 adopts helical teeth, and correspondingly, the first planetary gear 3213 adopts a helical tooth structure to reduce noise and improve transmission efficiency.

[0068] In one embodiment, the second inner gear sleeve 3221 is provided with a second tooth groove 3226, and the groove wall of the second tooth groove 3226 is configured as straight teeth. The second planetary gear set 322 includes a second planet carrier 3225, at least one second planet gear 3224 mounted on the second planet carrier 3225, and a transmission component. The second planet gear 3224 meshes with the first gear 3212 and the second tooth groove 3226 respectively.

[0069] Both the first gear 3212 and the second planetary gear 3224 adopt a spur gear structure. The first gear 3212 forms the sun gear located in the central area formed by the three second planetary gears 3224.

[0070] like Figure 3 and Figure 4 As shown, in one embodiment, the output end of the transmission component 32 is connected to a clutch mechanism 323, which controls the on / off control of the output power of the transmission component 32, and can control the power of the actuator.

[0071] In one optional embodiment, the clutch mechanism 323 is disposed within the second inner gear sleeve 3221, and the clutch mechanism 323 is assembled and connected to the second inner gear sleeve 3221. The second inner gear sleeve 3221 has a receiving cavity that communicates with the transmission cavity, and the clutch mechanism 323 is located within the receiving cavity.

[0072] Specifically, the transmission component of the second planetary gear set 322 passes through the receiving cavity and is connected to the clutch mechanism 323. The clutch mechanism 323 controls the engagement and disengagement of the power input to the transmission component. The first planetary gear set 321 and the second planetary gear set 322 constitute a two-stage reduction mechanism and are connected to the clutch mechanism 323, which can shorten the overall size and provide stable torque output.

[0073] In another embodiment, the transmission assembly 32 further includes a clutch housing, on which a clutch mechanism 323 is mounted, and the clutch housing is detachably connected to a second inner gear sleeve 3221.

Optionally, the clutch housing and the second inner gear sleeve 3221 are connected by fasteners.

[0074] In the above embodiment, the clutch mechanism 323 includes an iron part 3233, a clutch part 3231, a clutch output part 3234, and two magnetic beads 3232. The output end of the transmission assembly 32 is fixedly connected to the clutch part 3231. A clutch cavity is formed in the clutch output part 3234, and the two magnetic beads 3232 are located in the clutch cavity and are respectively located on both sides of the clutch part 3231. The inner wall of the clutch cavity is provided with grooves that are adapted to the magnetic beads 3232.

[0075] The clutch element 3231 has an approximately elliptical structure, and a space is formed between the clutch element 3231 and the cavity wall of the clutch chamber to accommodate the movement of the magnetic bead 3232. After the clutch element 3231 moves the magnetic bead 3232 into the groove, the clutch output element 3234 outputs power. When the magnetic bead 3232 disengages from the groove, the power to the clutch output element 3234 and the second planetary gear set 322 is disconnected.

[0076] The clutch output component 3234 has a partial protrusion to form an output shaft with a shaft-like protrusion. The output shaft passes through the second inner gear sleeve 3221 to form the power output part of the transmission assembly 32.

[0077] Furthermore, a connecting hole is provided on the clutch output component 3234, and the output end of the transmission assembly 32 extends into the connecting hole. The clutch component 3231 is fixed to the output end of the transmission assembly 32, and the output end of the transmission assembly 32 and the clutch output component 3234 are coaxially arranged, which improves the tightness of the connection between the transmission assembly 32 and the clutch mechanism 323, and improves the compactness in space.

[0078] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
