[0030] The utility model integrates the motor 2, the battery 3 and the control board 4 into the housing 1, and adopts a structure in which the motor 2, the battery 3 and the control board 4 are arranged in parallel with each other. The overall length is short, the structure is compact, and the space occupancy is small. It can be adapted to the top rail 11 of the existing manual dimming venetian blinds. The dimming motor can be quickly inserted from the top of the top rail 11 into the top rail 11 for clamping, and then the dimming rod 14 and the dimming motor can be plugged in to complete the assembly. The utility model has a small size and fast assembly, so that the traditional manual dimming venetian blinds can be converted into electric dimming venetian blinds, reducing resource waste.

[0031] Among them, see Figure 5 At least one transition gear 7 is provided between the first gear 5 and the second gear 6. When the distance between the first gear 5 and the second gear 6 is large, power can be transmitted through the transition gear 7, thereby playing the role of auxiliary transmission.

[0032] Among them, see Figure 2 , 3 , 4, a channel 1.5 for the dimming rod 14 to pass through is provided in the shell 1, and the channel 1.5 is arranged in parallel with the motor 2, the battery 3, and the control board 4. The second gear 6 and the channel 1.5 are located on the same straight line, which is convenient for the quick insertion of the dimming rod 14, and the setting of the channel 1.5 can protect the dimming rod 14 from hitting other components in the shell 1 when passing through, thereby playing a good protective role and having good guiding properties. In addition, the channel 1.5 is arranged in parallel with the motor 2, the battery 3, and the control board 4, with high space utilization and compact structure, and at the same time, it is convenient for the motor 2 to transmit power to the dimming rod 14 in parallel.

[0033] Among them, see Figure 2 , 3 The shell 1 includes a front cover 1.1, a rear cover 1.2 and a main body 1.3. The front cover 1.1 and the rear cover 1.2 are detachably connected to the two ends of the main body 1.3. A cavity 1.4 is provided in the main body 1.3 and passes through the two ends along the length direction of the main body 1.3. This structural arrangement facilitates the assembly and disassembly of the shell 1, and also facilitates subsequent maintenance and inspection. The detachable connection can be a snap connection, a screw connection, etc.

[0034] Among them, see Figure 2 , 3 , 4, 5, the channel 1.5, motor 2, battery 3, control board 4 are all arranged along the length direction of the shell 1, the motor 2 and battery 3 are located on both sides of the channel 1.5, and the control board 4 is located below the battery 3. The channel 1.5, motor 2, battery 3, control board 4 are arranged in parallel along the length direction of the shell 1, so that the overall length of the shell 1 is short, and the control board 4 is located parallel to the battery 3 below, with high space utilization and compact structure.

[0035] Among them, see Figure 1 The back cover 1.2 is exposed with a switch key 8, a setting key 9 and a power cord 10 electrically connected to the control board 4. The switch key 8 is used to switch the dimming motor, the setting key 9 is used for coding, reversing, and restoring factory settings, and the power cord 10 is used for charging. The back cover 1.2 is also provided with a line clamping position 1.6 for limiting the direction of the power cord 10. The line clamping position 1.6 can clamp the power cord 10 to prevent the power cord 10 from being placed arbitrarily and interfering with the transmission rod 12, the dimming rod 14 and other components in the top rail 11, making it safer to use.

[0036] Among them, see Figure 1 , 4 5. The bottom of the shell 1 is provided with a U-shaped groove 1.7 which is recessed inwards for avoiding the transmission rod 12. The U-shaped groove 1.7 runs through both ends of the shell 1 along the length direction. When the dimming motor is assembled with the top rail 11, the setting of the U-shaped groove 1.7 can avoid the transmission rod 12 in the top rail 11, so that the dimming motor will not press the transmission rod 12 when it is vertically inserted into the top rail 11, thereby ensuring that the transmission rod 12 can work normally. The dimming motor can be well adapted to the internal structure of the top rail 11 and is easy to assemble.

[0037] The battery 3 is a lithium battery, which can be charged and does not need to be replaced periodically, making it more convenient to use.

[0038] A Venetian blind, see Figure 6 , including a top rail 11, in which a transmission rod 12, a transmission driver 13, a dimming rod 14, a dimming driver, and a rope reel 15 are arranged. A louver 16 is connected to the bottom of the top rail 11. The rope reel 15 drives the louver 16 to open and close up and down through a rope reel 17. The dimming rod 14 drives the louver 16 to dim through a rope ladder 18. The transmission driver 13 drives the transmission rod 12 to drive the rope reel 15 to rotate, and the dimming driver drives the dimming rod 14 to rotate. The dimming driver is any of the dimming motors described above.

[0039] During assembly, the dimming motor can be vertically inserted from the top of the top rail 11, and the insertion position can avoid the rope reel 15 and the transmission drive member 13. The U-shaped groove 1.7 on the dimming motor can be inserted into the transmission rod 12 to avoid the transmission rod 12, and then the dimming rod 14 is connected with the dimming motor. Specifically, the dimming rod 14 is connected with the channel 1.5 on the dimming motor and the second gear 6 at the same time. After completing the above two steps, the manual dimming Venetian blinds can be quickly converted into electric dimming Venetian blinds, and the dimming motor drives the dimming rod 14 to rotate. The electric dimming is realized by the automatic operation. The overall size of the dimming motor is short and the assembly is fast. The traditional manual dimming Venetian blinds can be converted into electric dimming Venetian blinds, which reduces resource waste and meets market demand. It should also be noted that the dimming motor provided by the utility model is also suitable for manual Venetian blinds in which the dimming rod and the transmission rod are the same structure. When modifying, the dimming motor is vertically inserted into the top rail, and then the dimming rod and the dimming motor are connected. The dimming rod can both transmit the rope winder and dim the light, thereby converting the manual Venetian blinds into electric Venetian blinds.

[0040] Unless otherwise specified, the materials, reagents and experimental equipment involved in the embodiments of the present invention are all commercially available products in the field of blinds technology.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
