Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and in particular to a transmission component, a drive component, a drive device, and an electric curtain. Background Technology

[0002] Electric curtains generally include a drive unit, curtain rails, belts, and trolleys. The drive unit provides power to drive the belts and trolleys to move on the curtain rails, and the trolleys in turn drive the curtain body to move, thereby controlling the opening and closing of the curtain.

[0003] Current drive units are generally cylindrical in shape, with components such as the drive motor, reducer, clutch assembly, and output gear stacked vertically within the housing (i.e., all components are coaxial). This results in a relatively high overall height for the drive unit. When installed on a curtain track, the drive unit protrudes significantly, affecting the aesthetics of the motorized curtains. Furthermore, it may interfere with other surrounding components (e.g., cabinets or inward-opening windows near the curtains), thus compromising installation convenience and limiting its application. Utility Model Content

[0004] The purpose of this invention is to provide a transmission component that can reduce the height of the drive component and drive device, making the drive device more compact, which is beneficial to improving the aesthetics of electric curtains, reducing the risk of interference between the drive device and other surrounding components, and improving the convenience of installation.

[0005] This utility model provides a transmission component, including a first gear and a second gear, wherein the first gear is pulsatorically connected to the second gear, the first gear is pulsatorically connected to one of an input component and an output component, and the second gear is pulsatorically connected to the other of the input component and the output component; the first gear and the second gear are configured on different axes, so that the input component and the output component are configured on different axes.

[0006] In one possible implementation, the first gear and the second gear are arranged side by side, with the rotation axis of the first gear being parallel to the rotation axis of the second gear.

[0007] In one possible implementation, the transmission assembly further includes an intermediate transmission element through which the first gear and the second gear are connected.

[0009] And / or, the intermediate transmission component includes a timing belt that is wound around both the first gear and the second gear.

[0010] This utility model also provides a drive assembly, including an input assembly, an output assembly, and a transmission assembly as described above. The input assembly includes a drive motor. One of the drive motor and the output assembly is connected to the first gear, and the other of the drive motor and the output assembly is connected to the second gear. The drive motor can drive the output assembly to rotate through the transmission assembly. The drive motor and the output assembly are arranged on different axes.

[0011] In one possible implementation, both the drive motor and the output component are located above the transmission component.

[0012] In one possible implementation, the end of the output component on the side away from the transmission component does not extend beyond the end of the drive motor on the side away from the transmission component.

[0013] In one possible implementation, the first gear is coaxially arranged with the drive motor, and the second gear is coaxially arranged with the output component.

[0014] In one possible implementation, the rotation axis of the first gear is parallel to the rotation axis of the second gear, and the rotation axis of the drive motor is parallel to the rotation axis of the output component.

[0015] In one possible implementation, the drive assembly further includes a reduction mechanism disposed between the drive motor and the transmission assembly, the reduction mechanism being connected to both the drive motor and the first gear transmission.

[0016] In one possible implementation, the drive assembly further includes a clutch assembly disposed between the output assembly and the transmission assembly, the clutch assembly being connected to the output assembly and the second gear respectively; the clutch assembly has a first state and a second state;

[0017] When the clutch assembly is in the first state, the clutch assembly is coupled to the output assembly so that the clutch assembly and the output assembly are connected in a transmission manner; when the clutch assembly is in the second state, the clutch assembly is decoupled from the output assembly so that there is no transmission between the clutch assembly and the output assembly.

[0018] In one possible implementation, the drive assembly further includes a drive shaft disposed between the clutch assembly and the transmission assembly, with both ends of the drive shaft connected to the clutch assembly and the second gear, respectively.

[0019] In one possible implementation, the drive assembly further includes an electronic control assembly and a power supply assembly, the power supply assembly being electrically connected to the electronic control assembly, and the electronic control assembly being electrically connected to the drive motor; both the electronic control assembly and the power supply assembly are disposed on the side of the transmission assembly closer to the output assembly.

[0020] This utility model also provides a driving device, including a housing and a driving component as described above, wherein the driving component is disposed within the housing.

[0021] In one possible implementation, the housing has a support structure, on which at least a portion of the drive assembly is disposed.

[0022] This utility model also provides an electric curtain, including a curtain box assembly and a drive device as described above, wherein the drive device is disposed on the curtain box assembly.

The opening / closing assembly is used to connect to the curtain body. A curtain box assembly is disposed at the end of the guide rail. An output assembly is drivenly connected to the linkage assembly. The drive motor can drive the output assembly to rotate through the transmission assembly, thereby driving the opening / closing assembly to slide along the guide rail through the linkage assembly, and thus driving the curtain body to open and close.

[0025] The transmission assembly provided by this utility model, because the first gear and the second gear are set with different shafts, allows the input assembly and the output assembly to be set with different shafts. This reduces the height of the drive assembly and the drive device, making the drive device more compact, which is beneficial to improving the aesthetics of the electric curtains, reducing the risk of interference between the drive device and other surrounding components, and improving the convenience of installation.

Detailed Implementation

[0042] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0043] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and claims of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0044] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this utility model.

[0045] like Figures 4 to 6As shown, this embodiment of the present invention provides a driving device 1, including a housing 17 and a driving assembly 10 disposed within the housing 17. The driving assembly 10 includes an input assembly, a transmission assembly 12, and an output assembly 13. The input assembly includes a drive motor 11, and the transmission assembly 12 is connected to both the drive motor 11 and the output assembly 13. The drive motor 11 provides a power source and can drive the output assembly 13 to rotate via the transmission assembly 12. The rotation axis of the input assembly and the rotation axis of the output assembly 13 are not on the same straight line, that is, the input assembly and the output assembly 13 are arranged with different axes. Specifically, the rotation axis of the drive motor 11 and the rotation axis of the output assembly 13 are not on the same straight line, that is, the drive motor 11 and the output assembly 13 are arranged with different axes.

[0046] Specifically, in this embodiment, the drive assembly 10, since the drive motor 11 and the output assembly 13 are set with different axes, that is, the drive motor 11 and the output assembly 13 do not need to be stacked one on top of the other, thereby reducing the height of the drive assembly 10 and the drive device 1, making the drive device 1 more compact, which is beneficial to improving the aesthetics of the electric curtain, reducing the risk of interference between the drive device 1 and other surrounding components, and improving the convenience of installation.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the drive motor 11 has an output shaft 110, which is connected to the transmission assembly 12. The rotation axis of the output shaft 110 and the rotation axis of the output assembly 13 are not on the same straight line, that is, the output shaft 110 and the output assembly 13 are set with different axes.

[0048] like Figure 5 and Figure 6 As shown, in one embodiment, along the direction of the rotation axis of the drive motor 11 (that is, the extension direction of the output shaft 110), the drive motor 11 and the output component 13 are located on the same side of the transmission component 12 (in this embodiment, the drive motor 11 and the output component 13 are both located above the transmission component 12), thereby reducing the height of the drive component 10 and the drive device 1.

[0049] like Figure 5 and Figure 6 As shown, in one embodiment, along the rotation axis of the drive motor 11, the end of the output component 13 away from the transmission component 12 does not extend beyond the end of the drive motor 11 away from the transmission component 12, so as to avoid the height of the output component 13 being too large and increasing the height of the drive component 10 and the drive device 1.

[0050] like Figure 5 , Figure 6 and Figure 14 As shown, in one embodiment, the transmission assembly 12 includes a first gear 121 and a second gear 122, with the first gear 121 and the second gear 122 being drive-connected. The first gear 121 is drive-connected to one of the input assembly (drive motor 11) and the output assembly 13, and the second gear 122 is drive-connected to the other of the input assembly (drive motor 11) and the output assembly 13. Specifically, in this embodiment, the drive motor 11 is drive-connected to the first gear 121, and the output assembly 13 is drive-connected to the second gear 122. The rotation axis of the first gear 121 and the rotation axis of the second gear 122 are not on the same straight line, that is, the first gear 121 and the second gear 122 are set with different axes, so that the input assembly (drive motor 11) and the output assembly 13 are set with different axes, that is, the rotation axis of the input assembly (drive motor 11) and the rotation axis of the output assembly 13 are not on the same straight line. The first gear 121 and the second gear 122 can be the same size or different size.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment, the first gear 121 and the second gear 122 are arranged side by side, with the rotation axis of the first gear 121 and the rotation axis of the second gear 122 parallel to each other. The drive motor 11 and the output component 13 are arranged side by side, with the first gear 121 and the drive motor 11 coaxially arranged, and the second gear 122 and the output component 13 coaxially arranged, with the rotation axis of the drive motor 11 and the rotation axis of the output component 13 parallel to each other.

[0052] like Figure 5 , Figure 6 and Figure 14 As shown, in one embodiment, the transmission assembly 12 further includes an intermediate transmission member 123, through which the first gear 121 and the second gear 122 are connected.

[0053] like Figure 5 , Figure 6 and Figure 14 As shown, in one embodiment, the intermediate transmission member 123 includes a transmission gear 1231, which meshes with a first gear 121 and a second gear 122, respectively. The first gear 121 and the second gear 122 can transmit power through the transmission gear 1231. In this embodiment, there is one transmission gear 1231; in other embodiments, there may be multiple transmission gears 1231, that is, the first gear 121 and the second gear 122 transmit power through a multi-stage gear system.

[0054] like Figure 15As shown, in another embodiment, the intermediate transmission member 123 includes a timing belt 1232, which is wound around both the first gear 121 and the second gear 122. The first gear 121 and the second gear 122 can transmit power through the timing belt 1232. Of course, in other embodiments, the intermediate transmission member 123 can also take other forms, for example, the intermediate transmission member 123 may include both the transmission gear 1231 and the timing belt 1232. In other embodiments, the intermediate transmission member 123 may not be provided, and the first gear 121 and the second gear 122 may directly mesh for transmission.

[0055] like Figure 5 and Figure 6 As shown, in one embodiment, the drive assembly 10 further includes a reduction mechanism 14, which is disposed between the drive motor 11 and the transmission assembly 12. The reduction mechanism 14 is driveably connected to both the drive motor 11 and the transmission assembly 12. Specifically, the reduction mechanism 14 is driveably connected to the output shaft 110 of the drive motor 11 and the first gear 121. The reduction mechanism 14 is used to convert the high speed and low torque of the drive motor 11 into low speed and high torque, that is, the reduction mechanism 14 plays the role of speed reduction and torque increase. The reduction mechanism 14 is generally a gear system, that is, the reduction mechanism 14 adopts the form of multiple gear meshing. Specifically, the reduction mechanism 14 can be a planetary reduction mechanism, a parallel shaft gear reduction mechanism, a harmonic reduction mechanism, etc.

[0056] like Figure 5 , Figure 6 and Figures 10 to 12 As shown, in one embodiment, the drive assembly 10 further includes a clutch assembly 15, which is disposed between the output assembly 13 and the transmission assembly 12. The clutch assembly 15 is connected to both the output assembly 13 and the transmission assembly 12. Specifically, the clutch assembly 15 is connected to the output assembly 13 and the second gear 122 for transmission. The clutch assembly 15 functions as a disengagement mechanism, enabling transmission between the output assembly 13 and the transmission assembly 12, or preventing transmission altogether.

[0057] The clutch assembly 15 has a first state and a second state. When the clutch assembly 15 is in the first state, the clutch assembly 15 is coupled to the output assembly 13 so that the clutch assembly 15 and the output assembly 13 are connected for transmission. At this time, the output assembly 13 and the transmission assembly 12 can be transmitted through the clutch assembly 15. When the clutch assembly 15 is in the second state, the clutch assembly 15 is decoupled from the output assembly 13 so that the clutch assembly 15 and the output assembly 13 are not transmitted. At this time, the output assembly 13 and the transmission assembly 12 cannot be transmitted through the clutch assembly 15.

[0058] By setting the clutch assembly 15, the electric opening and closing of the electric curtain can be switched between electric and manual operation. Specifically, when the clutch assembly 15 is in the first state, the curtain (not shown) can be opened and closed by the drive motor 11, thus achieving electric opening and closing of the electric curtain; when the clutch assembly 15 is in the second state, the curtain can be opened and closed manually without driving the drive motor 11 to rotate (that is, when the curtain is manually pulled open and closed, since the clutch assembly 15 is decoupled from the output assembly 13, the opening and closing movement of the curtain will not cause the transmission assembly 12 to rotate, and therefore will not drive the drive motor 11 to rotate), thus achieving manual opening and closing of the electric curtain.

[0059] like Figure 5 , Figure 6 and Figures 10 to 12 As shown, in one embodiment, the drive assembly 10 further includes a drive shaft 150, which is disposed between the clutch assembly 15 and the transmission assembly 12. Both ends of the drive shaft 150 are connected to the clutch assembly 15 and the transmission assembly 12, respectively. Specifically, both ends of the drive shaft 150 are connected to the clutch assembly 15 and the second gear 122 for transmission.

[0060] like Figures 4 to 9 As shown, in one embodiment, a support structure (not labeled) is fixedly provided inside the housing 17, and at least a portion of the drive assembly 10 is disposed on the support structure.

[0061] like Figures 4 to 9 As shown, in one embodiment, the housing 17 includes a top cover 17A, a main housing 17B, and a bottom housing 17C. The main housing 17B has openings at both its top and bottom (not labeled). The top cover 17A is connected to the top opening of the main housing 17B, and the bottom housing 17C is connected to the bottom opening of the main housing 17B. The support structure includes a mounting portion 173 and a support base 174 disposed within the housing 17. The mounting portion 173 is an integral structure with the housing 17; the support base 174 is located below the mounting portion 173 and is fixedly connected to the mounting portion 173.

[0062] The drive motor 11 and the clutch assembly 15 are both mounted on the mounting part 173, the reduction mechanism 14 is mounted on the support base 174 (specifically, the support base 174 is provided with a mounting groove 175, and the reduction mechanism 14 is mounted in the mounting groove 175), the transmission assembly 12 is mounted on the bottom shell 17C, the output assembly 13 is mounted between the top cover 17A and the mounting part 173, and the transmission shaft 150 passes through the mounting part 173 and the support base 174.

[0063] The base shell 17C is equipped with a first bearing 161, a second bearing 162, and a third bearing 163. A first gear 121 is rotatably connected to the base shell 17C via the first bearing 161, a second gear 122 is rotatably connected to the base shell 17C via the second bearing 162, and a transmission gear 1231 is rotatably connected to the base shell 17C via the third bearing 163, allowing the first gear 121, the second gear 122, and the transmission gear 1231 to rotate smoothly. A fourth bearing 164 is provided between the drive shaft 150 and the mounting portion 173 to ensure stable and smooth rotation of the drive shaft 150. A clearance hole 172 is provided on the top cover 17A corresponding to the position of the output component 13, allowing the output component 13 to protrude through the clearance hole 172 for easy connection to external devices. A fifth bearing 165 is provided between the output component 13 and the top cover 17A to ensure stable and smooth rotation of the output component 13.

[0064] like Figure 5 , Figure 6 and Figures 9 to 12 As shown, in one embodiment, the output assembly 13 includes an integrally connected output gear part 131 and a clutch disc 132. The output gear part 131 is used to connect to an external device. The clutch disc 132 has a groove 133, and the inner sidewall of the groove 133 has a slot 134. The clutch assembly 15 includes a cam 151, a magnetic ball 152, a magnetic ring 153, and a pressure cover 154. The cam 151 and the magnetic ball 152 are both located in the groove 133. The cam 151 can rotate within the groove 133. The cam 151 is connected to the drive shaft 150. The cam 151 has a spindle-shaped structure, and the magnetic ball 152 is located between the outer wall of the cam 151 and the inner sidewall of the groove 133. The magnetic ring 153 and the pressure cap 154 ​​are located on the side of the cam 151 away from the output assembly 13. The pressure cap 154 ​​serves two purposes: firstly, to cover the opening of the groove 133 to prevent the magnetic ball 152 from falling out of the groove 133; secondly, to fix the magnetic ring 153 to the mounting part 173. Both the magnetic ball 152 and the magnetic ring 153 are made of magnetic material, and the magnetic ring 153 can attract the magnetic ball 152 through magnetic force.

[0065] Specifically, when the drive motor 11 is running, the drive motor 11 drives the cam 151 to rotate in the groove 133 in sequence through the reduction mechanism 14, the transmission component 12 and the transmission shaft 150. Due to the special shape of the cam 151, the cam 151 will push the magnetic ball 152 to move during the rotation, so that the magnetic ball 152 is stuck in the slot 134. When the magnetic ball 152 is stuck in the slot 134, the magnetic ball 152 will prevent the cam 151 from moving relative to the clutch disc 132. That is, at this time, the cam 151-magnetic ball 152-clutch disc 132 are connected as a whole, that is, the clutch component 15 is coupled with the output component 13, so that when the cam 151 continues to rotate, it can drive the output component 13 to rotate together. When the drive motor 11 stops operating (or the drive motor 11 rotates in the opposite direction by a small angle), the magnetic ball 152 will reset under the magnetic attraction of the magnetic ring 153, that is, the magnetic ball 152 will disengage from the slot 134, and the clutch assembly 15 will be decoupled from the output assembly 13. At this time, the rotation of the output assembly 13 cannot be transmitted to the clutch assembly 15. For the specific structure and working principle of the clutch assembly 15, please refer to the prior art, which will not be elaborated here.

[0066] like Figure 5 and Figure 6 As shown, in one embodiment, the drive assembly 10 further includes an electronic control assembly 191, a power supply assembly 192, and a power cord 193. Both the electronic control assembly 191 and the power supply assembly 192 are located within the housing 17. The power supply assembly 192 is electrically connected to the electronic control assembly 191, and the electronic control assembly 191 is electrically connected to the drive motor 11. Both the electronic control assembly 191 and the power supply assembly 192 are disposed on the side of the transmission assembly 12 near the output assembly 13. One end of the power cord 193 is located outside the housing 17, and the other end of the power cord 193 passes through the housing 17 (specifically, through the bottom shell 17C) and connects to the power supply assembly 192.

[0067] Specifically, in this embodiment, both the electronic control component 191 and the power supply component 192 are mounted on the support base 174. The electronic control component 191 includes a control circuit board (not labeled) and electronic components mounted on the control circuit board. The electronic control component 191 is used to wirelessly connect to external devices to receive remote commands and control the operation of the drive motor 11. The power supply component 192 includes a power circuit board (not labeled) and electronic components mounted on the power circuit board. The power supply component 192 is used to supply power to the entire drive device 1. The power cord 193 includes a plug and a wire (not labeled). The plug is used to connect to mains power, and the wire is electrically connected between the plug and the power supply component 192.

[0068] like Figures 1 to 6 As shown, this utility model embodiment also provides an electric curtain, including a curtain box assembly 3 and the aforementioned drive device 1, with the drive device 1 disposed on the curtain box assembly 3.

[0069] like Figures 1 to 6 As shown, in one embodiment, along the direction of the rotation axis of the drive motor 11, both the drive motor 11 and the output component 13 are located on the side of the transmission component 12 close to the curtain box component 3.

[0070] like Figures 1 to 6 As shown, in one embodiment, the electric curtain also includes a curtain rod assembly 2. The curtain rod assembly 2 includes a guide rail 21, an opening / closing assembly 22 that can slide along the guide rail 21, and a linkage assembly 23 connected to the opening / closing assembly 22. The opening / closing assembly 22 is used to connect to the curtain body (not shown). The curtain box assembly 3 is disposed at the end of the guide rail 21, and the output assembly 13 is connected to the linkage assembly 23 for transmission. The drive motor 11 can drive the output assembly 13 to rotate through the transmission assembly 12, thereby driving the opening / closing assembly 22 to slide along the guide rail 21 through the linkage assembly 23, and thus driving the curtain body to open and close.

[0071] Specifically, in this embodiment, the guide rail 21 is provided with a sliding groove 211, and the opening and closing component 22 is slidably connected to the guide rail 21, allowing the opening and closing component 22 to slide along the sliding groove 211. The opening and closing component 22 includes a trolley 221 and a lug 222, both of which are used to connect to the curtain body. Both the trolley 221 and the lug 222 are connected to the linkage component 23, and the drive motor 11 can drive the trolley 221 and the lug 222 to slide along the guide rail 21 through the linkage component 23, thereby driving the curtain body to open and close. For the specific structure and working principle of the opening and closing component 22, please refer to the prior art, which will not be elaborated here.

[0072] like Figures 1 to 6 As shown, in one embodiment, the curtain box assembly 3 includes a first curtain box 31 and a second curtain box 32. The first curtain box 31 and the second curtain box 32 are respectively fixedly disposed at both ends of the guide rail 21, and the driving device 1 is disposed on the first curtain box 31 or the second curtain box 32.

[0073] The linkage assembly 23 includes a drive wheel 231, a driven wheel 232, and a transmission belt 233. The drive wheel 231 is disposed in one of the first curtain box 31 and the second curtain box 32, and the driven wheel 232 is disposed in the other of the first curtain box 31 and the second curtain box 32. The transmission belt 233 passes through the guide rail 21, and the two ends of the transmission belt 233 are respectively wound around the drive wheel 231 and the driven wheel 232. The opening and closing assembly 22 is connected to the driven wheel 232.

[0074] The output component 13 is connected to the drive wheel 231 via a transmission; the drive motor 11 can drive the output component 13 to rotate through the transmission component 12, thereby driving the drive wheel 231, the transmission belt 233 and the driven wheel 232 to rotate, and thus driving the opening and closing component 22 to slide along the guide rail 21.

[0075] Specifically, in this embodiment, the drive device 1 is disposed on the first curtain box 31, the drive wheel 231 is disposed inside the first curtain box 31 and rotatably connected to the first curtain box 31, and the driven wheel 232 is disposed inside the second curtain box 32 and rotatably connected to the second curtain box 32. The drive wheel 231 includes a first gear part 2311 and a second gear part 2312 integrally connected, and the two ends of the transmission belt 233 are respectively wound around the first gear part 2311 and the driven wheel 232; the second gear part 2312 extends into the housing 17 through the clearance hole 172 on the top cover 17A and meshes with the output component 13 (specifically meshing with the output gear part 131).

[0076] like Figures 1 to 6 and Figure 13 As shown, in one embodiment, the drive device 1 further includes a snap-fit ​​assembly 18, which is connected to the housing 17. The snap-fit ​​assembly 18 includes a snap-fit ​​portion 181, and the curtain box assembly 3 is provided with a mating portion 311. The snap-fit ​​portion 181 can engage with the mating portion 311 to fix the housing 17 to the curtain box assembly 3. Specifically, in this embodiment, the mating portion 311 is disposed on the first curtain box 31, and the housing 17 can be fixed to the first curtain box 31 by snap-fitting the snap-fit ​​portion 181.

[0077] like Figures 1 to 6 and Figure 13 As shown, in one embodiment, the housing 17 is provided with a protrusion 171 (in this embodiment, the protrusion 171 is provided on the top cover 17A), and at least part of the drive motor 11 is located inside the protrusion 171. The curtain box assembly 3 is provided with a receiving groove 312, and the protrusion 171 is located inside the receiving groove 312; a snap-fit ​​part 181 is provided on the protrusion 171, and a mating part 311 is provided on the inner wall of the receiving groove 312.

[0078] Specifically, in this embodiment, the receiving groove 312 is provided on the first curtain box 31. A first through hole 176 is provided on the side wall of the protrusion 171, and the engaging part 181 protrudes from the protrusion 171 through the first through hole 176, thereby enabling the engaging part 181 to engage with the mating part 311. By providing the receiving groove 312, the protrusion 171 can extend into the receiving groove 312, thereby reducing the height of the drive device 1 after it is installed on the curtain box assembly 3, further improving aesthetics and further reducing the risk of interference between the drive device 1 and other surrounding components.

[0079] like Figures 1 to 6 and Figure 13As shown, in one embodiment, the latching part 181 has a locked state and an unlocked state; when the latching part 181 is in the locked state, the latching part 181 engages with the docking part 311, and the drive device 1 is fixed on the curtain box assembly 3; when the latching part 181 is in the unlocked state, the latching part 181 disengages from the docking part 311, and the drive device 1 can be removed from the curtain box assembly 3. This arrangement facilitates the installation and removal of the drive device 1.

[0080] like Figures 1 to 6 and Figure 13 As shown, in one embodiment, the latching assembly 18 further includes an unlocking part 183 and an elastic member 184, both of which are connected to the latching part 181. The elastic member 184 is used to drive the latching part 181 from the unlocked state to the locked state by elastic force. The latching part 181 can be changed from the locked state to the unlocked state by manipulating the unlocking part 183.

[0081] Specifically, in this embodiment, the snap-fit ​​assembly 18 further includes a connecting portion 182. Both the connecting portion 182 and the elastic element 184 are located within the housing 17. The unlocking portion 183 and the snap-fit ​​portion 181 are respectively connected to both ends of the connecting portion 182. The elastic element 184 is a spring, and its two ends abut against the connecting portion 182 and the top cover 17A, respectively. The unlocking portion 183 is an unlocking button. A second through hole 177 is provided on the housing 17 (specifically, on the main housing 17B), and the unlocking portion 183 extends out of the housing 17 through the second through hole 177. When the unlocking part 183 is pressed, it pushes the engaging part 181 to move away from the unlocking part 183, thereby disengaging the engaging part 181 from the mating part 311. That is, the engaging part 181 changes from a locked state to an unlocked state, while the elastic member 184 compresses and stores force. When the unlocking part 183 is no longer pressed, the engaging part 181 moves towards the unlocking part 183 under the elastic force of the elastic member 184, allowing it to engage with the mating part 311. That is, the engaging part 181 changes from an unlocked state to a locked state. Of course, in other embodiments, the engaging assembly 18 can have other structures.
