[0047] According to a first aspect of this application, a driving device is provided.

[0048] like Figures 1 to 14As shown, the driving device provided in the embodiments of this application includes a base assembly 10 and a driving assembly 20. The base assembly 10 includes a base 11 and a first connector 13. The base 11 is fixedly installed on the lamp housing 100 by screws 101. The first connector 13 is detachably connected to the base 11, and the connecting wire 133 of the first connector 13 extends into the lamp housing 100. The base 11 has a surrounding wall 111 protruding away from the lamp housing 100. The driving assembly 20 includes a housing 21, a driving circuit 22, and a second connector 23. The housing 21 has a receiving space 211 and an opening end 212 communicating with the receiving space 211. The driving circuit 22 is disposed in the receiving space 211. The second connector 23 is detachably connected to the opening end 212 and electrically connected to the driving circuit 22. The second connector 23 is used for electrical connection with the first connector 13. In some embodiments of the drive device, the inner sidewall of the enclosure 111 is provided with a first mounting structure 112, and the outer sidewall of the second connector 23 or the outer sidewall of the housing 21 is provided with a second mounting structure 213. The open end 212 is abutted against the enclosure 111, and the second mounting structure 213 is detachably connected to the first mounting structure 112. In other embodiments of the drive device, the drive device further includes a locking ring 41, which is movably sleeved on the housing 21. The outer sidewall of the housing 21 is provided with a first stop surface 42, and the locking ring 41 is provided with a second stop surface 43. The outer sidewall of the enclosure 111 is provided with the first mounting structure 112, and the inner sidewall of the locking ring 41 is provided with the second mounting structure 213. The second mounting structure 213 is detachably connected to the first mounting structure 112, so that the first stop surface 42 and the second stop surface 43 abut against each other, and the end face of the open end 212 abuts against the base 11.

[0049] The base 11 of the base assembly 10 of the driving device in this application is fixedly installed on the lamp housing 100. The first mounting structure 112 on the base assembly 10 is detachably connected to the second mounting structure 213 on the driving assembly 20, or the first mounting structure 112 on the base assembly 10 is detachably connected to the second mounting structure 213 of the locking ring 41. The second connector 23 of the driving assembly 20 and the first connector 13 of the base assembly 10 are simultaneously electrically connected. Thus, the entire driving assembly 20 is located outside the lamp housing 100. This assembly structure can improve assembly efficiency. When the driving device needs to be repaired or replaced, generally only the driving assembly 20 needs to be repaired or replaced. Since the entire driving assembly 20 is located outside the lamp housing 100, and the first mounting structure 112 and the second mounting structure 213 are detachably connected, the driving assembly 20 can be quickly removed from the base assembly 10 simply by disassembling and separating the first mounting structure 112 and the second mounting structure 213, thus improving the efficiency of disassembling and repairing the driving device. After the drive unit is repaired, the entire drive unit can be quickly assembled onto the lamp housing, or the new drive unit can be quickly assembled onto the lamp housing.

[0050] In some embodiments of the driving device of this application, such as Figures 2 to 5 As shown, the second mounting structure 213 is disposed on the outer side wall of the second connector 23. Figure 3 and Figure 5 As shown, the first mounting structure 112 includes a plurality of first helical ribs 113, which are spaced apart circumferentially, such as... Figure 6 As shown, the second mounting structure 213 includes a plurality of second helical ribs 217, which are spaced apart circumferentially. Combined with Figure 3 , Figure 5 and Figure 6 As shown, the enclosure 111 is inserted into the opening end 212. The end of the enclosure 111 is located between the inner wall of the outer shell 21 and the outer wall of the second connector 23, and the three are sealed together. Multiple first spiral ribs 113 cooperate with multiple second spiral ribs 217 one by one when the drive assembly 20 rotates relative to the base 11 at a predetermined angle, so as to restrict the drive assembly 20 from disengaging from the base 11 along the axial direction of the drive device. When the end of the enclosure 111 is inserted into the opening 212, multiple first spiral ribs 113 are inserted at multiple intervals corresponding to multiple second spiral ribs 217. After the first spiral ribs 113 and the second spiral ribs 217 move and intersect along the axial direction of the drive device, the drive assembly 20 is rotated relative to the base assembly 10. At this time, the multiple first spiral ribs 113 and the multiple second spiral ribs 217 rotate relative to each other, and the multiple first spiral ribs 113 block the multiple second spiral ribs 217 in the axial direction, thereby restricting the drive assembly 20 from detaching from the base 11 along the axial direction of the drive device, thus completing the quick assembly operation between the base assembly 10 and the drive assembly 20.

[0051] like Figure 5 As shown, the first mounting structure 112 also includes a plurality of first anti-loosening ribs 114, each corresponding to a plurality of first helical ribs 113, and the first anti-loosening ribs 114 extend along the axial direction of the driving device. Figure 3 and Figure 5 As shown, the second mounting structure 213 also includes a plurality of first locking ribs 218, which are alternately spaced with a plurality of second spiral ribs 217 in a circumferential manner. After the drive assembly 20 is rotated relative to the base assembly 10, the first anti-loosening rib 114 will engage in the gap between the first locking ribs 218 and the second spiral ribs 217, thereby preventing the drive assembly 20 from easily rotating in the opposite direction relative to the base 11 and causing the drive assembly 20 to detach from the base 11, ensuring that the drive assembly 20 can be stably mounted on the base assembly 10.

[0052] In order for the second helical rib 217 to be rotated quickly and accurately to form a restrictive fit with the first helical rib 113, such as Figure 5 and Figure 6 As shown, the first mounting structure 112 also includes a guide rib 117, which is used to rotate and guide the second spiral rib 217.

[0053] In other embodiments of the driving device of this application, such as Figures 7 to 11 As shown, the second mounting structure 213 is disposed on the outer side wall of the housing 21. Figure 10 As shown, the first mounting structure 112 includes a plurality of first helical ribs 113, which are spaced apart circumferentially, such as... Figure 8 , Figure 10 and Figure 11 As shown, the second mounting structure 213 includes a plurality of second helical ribs 217, which are spaced apart circumferentially, and, as... Figures 7 to 11 As shown, the outer side wall of the outer casing 21 is also provided with an annular protrusion 219. When the drive assembly 20 is assembled onto the base assembly 10, the open end 212 is inserted into the enclosure 111, and the end of the enclosure 111 abuts against the annular protrusion 219 and is sealed. When the drive assembly 20 rotates relative to the base 11 by a predetermined angle, the multiple first helical ribs 113 correspond one-to-one with the multiple second helical ribs 217 to restrict the drive assembly 20 from disengaging from the base 11 along the axial direction of the drive device. When the end of the enclosure 111 is inserted into the opening 212, multiple first spiral ribs 113 are inserted at multiple intervals corresponding to multiple second spiral ribs 217. After the first spiral ribs 113 and the second spiral ribs 217 move and intersect along the axial direction of the drive device, the drive assembly 20 is rotated relative to the base assembly 10. At this time, the multiple first spiral ribs 113 and the multiple second spiral ribs 217 rotate relative to each other, and the multiple first spiral ribs 113 block the multiple second spiral ribs 217 in the axial direction, thereby restricting the drive assembly 20 from detaching from the base 11 along the axial direction of the drive device, thus completing the quick assembly operation between the base assembly 10 and the drive assembly 20.

[0054] like Figure 10 As shown, the first mounting structure 112 also includes a plurality of second locking ribs 115, which are alternately spaced with the plurality of first spiral ribs 113 in a circumferential direction. Figure 8 , Figure 10 and Figure 11As shown, the second mounting structure 213 also includes a plurality of second anti-loosening ribs 220, each corresponding to a second spiral rib 217, and the second anti-loosening ribs 220 extend along the axial direction of the drive device. When the drive assembly 20 rotates relative to the base 11 by a predetermined angle, the second anti-loosening ribs 220 are engaged in the gap between the second locking rib 115 and the first spiral rib 113, thereby preventing the drive assembly 20 from easily rotating in the opposite direction relative to the base 11 and causing the drive assembly 20 to detach from the base 11, ensuring that the drive assembly 20 can be stably mounted on the base assembly 10.

[0055] Furthermore, such as Figure 8 , Figure 10 and Figure 11 As shown, the second mounting structure 213 also includes a plurality of third helical ribs 222, which are spaced apart circumferentially. Each of the third helical ribs 222 corresponds to a plurality of second locking ribs 115, and the second locking ribs 115 slide along the third helical ribs 222. That is, when the drive assembly 20 rotates relative to the base 11 by a predetermined angle, the third helical ribs 222 guide the second locking ribs 115, thereby ensuring that the second locking ribs 115 slide along the third helical ribs 222 until the second anti-loosening ribs 220 are engaged in the gap between the second locking ribs 115 and the first helical ribs 113. This restricts the drive assembly 20 from easily rotating in the opposite direction relative to the base 11, which could cause the drive assembly 20 to detach from the base 11, thus ensuring that the drive assembly 20 can be stably mounted on the base assembly 10.

[0056] In some embodiments, such as Figure 13 and Figure 14 As shown, when the locking ring 41 is connected to the base 11 via the first mounting structure 112 and the second mounting structure 213, the first mounting structure 112 has an external thread, and the second mounting structure 213 has an internal thread that is adapted to the external thread for screwing. When assembling the drive assembly 20 onto the base assembly 10, simply rotate the locking ring 41 so that the second stop surface 43 of the locking ring 41 abuts against the first stop surface 42, and pushes the drive assembly 20 until the end face of the opening end 212 of the housing 21 abuts against the base 11, thereby securely fixing the drive assembly 20 to the base 11. Furthermore, during the rotation of the locking ring 41, the first connector 13 and the second connector 23 are electrically connected by contact, and the first connector 13 and the second connector 23 remain relatively stationary at all times, preventing the connection wire or connector pin between the first connector 13 and the second connector 23 from disconnecting due to relative rotation between the first connector 13 and the second connector 23, thus ensuring the effectiveness of the drive device.

[0057] And, as Figure 12 and Figure 13As shown, the cross-sectional profile of the locking ring 41 perpendicular to its central axis is a regular polygon. This allows the operator to rotate the locking ring 41 by hand or by using a tool (such as a wrench). This is particularly convenient for operators using tools to rotate the locking ring 41 to disassemble the drive assembly 20, protecting their hands from burns caused by the overheated surface of the drive assembly 20 after prolonged use. Of course, when the operator rotates the locking ring 41 by hand, their hands do not come into contact with the overheated surface of the drive assembly 20, thus preventing burns.

[0058] In some embodiments of this application, the base 11 of the drive device is provided with a central hole 116, and the first connector 13 is provided with a stepped surface 131 and a plurality of hooks 132 spaced circumferentially. The circumferential edge region of the central hole 116 is detachably snapped between the stepped surface 131 and the plurality of hooks 132. The first connector 13 is quickly assembled onto the base 11 by snap-fit ​​assembly, resulting in high assembly efficiency.

[0059] In some embodiments of this application, the inner wall of the housing 21 of the drive device is provided with a plurality of first snap-fit ​​portions 223 along the circumferential direction, and the second connector 23 is provided with a second snap-fit ​​portion 231 corresponding to the plurality of first snap-fit ​​portions 223. The first snap-fit ​​portions 223 and the second snap-fit ​​portions 231 are detachably snap-fitted together. The second connector 23 is quickly assembled into the receiving space 211 of the housing 21 by means of snap-fit ​​assembly, which has high assembly efficiency.

[0060] In the driving device of this application, such as Figure 3 , Figure 5 and Figure 6 As shown, the base 11 has a central hole 116, the first connector 13 has a stepped surface 131 and a plurality of hooks 132 spaced circumferentially, the circumferential edge area of ​​the central hole 116 is detachably snapped between the stepped surface 131 and the plurality of hooks 132, and the inner sidewall of the housing 21 has a plurality of first snap-fit ​​parts 223 circumferentially, the second connector 23 has a second snap-fit ​​part 231 corresponding to the plurality of first snap-fit ​​parts 223, and the first snap-fit ​​parts 223 and the second snap-fit ​​parts 231 are detachably snapped together.

[0061] In some embodiments of the driving device of this application, such as Figure 8 and Figure 11 As shown, the inner wall of the outer casing 21 is provided with a plurality of first protrusions 224 and second protrusions 225, with the plurality of first protrusions 224 corresponding one-to-one with the plurality of second protrusions 225 and spaced apart along the axial direction of the driving device. In this way, the circumferential edge of the driving circuit 22 can be engaged in the gap between the first protrusions 224 and the second protrusions 225, and the driving circuit 22 is thus fixedly engaged within the receiving space 211.

[0062] In some embodiments of the driving device of this application, such as Figures 3 to 5 , Figures 8 to 11 As shown, the drive assembly 20 also includes a light-transmitting element 25, and the housing 21 includes an integrally formed circumferential sidewall 215 and a top wall 216. The circumferential sidewall 215 and / or the top wall 216 are provided with mounting windows 214, and the light-transmitting element 25 is mounted in the mounting window 214, as shown. Figure 5 and Figure 10 As shown, the driving circuit 22 is equipped with a light sensor 221, which is used to receive light transmitted from the light-transmitting element 25 into the receiving space 211. In the driving device of this embodiment, light can be transmitted from the light-transmitting element 25 into the receiving space 211 of the housing 21. The light sensor 221 located in the receiving space 211 can receive the light transmitted into the receiving space 211, thereby controlling the LED light source of the LED lamp to automatically light up or turn off by means of photosensing, which greatly facilitates the user and improves the user experience. In addition, the driving device also includes a third sealing member 33, which is disposed between the light-transmitting element 25 and the hole wall of the mounting window 214 to form a seal.

[0063] like Figures 1 to 3 , Figures 7 to 10 As shown, the driving device of this application also includes a first sealing element 31 and a second sealing element 32. The first sealing element 31 is disposed between the base 11 and the outer surface of the lamp housing 100. When the screw 101 locks the base 11 and the lamp housing 100, the base 11 and the lamp housing 100 compress the first sealing element 31 to deform and form a seal.
