When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0022] The present utility model provides a short curtain motor structure.

[0023] The short curtain motor structure of this embodiment includes a housing 1 and a driving motor, a gear set, a control circuit board 4, and a power supply circuit board 5 installed inside the housing; the upper and lower ends of the housing are open and are detachably connected with a top cover 6 and a base 7, and a vertically arranged partition 11 is installed inside the housing; in addition, a casing 8 is installed inside the housing, the driving motor and the gear set are installed inside the casing, the control circuit board is vertically arranged and is detachably installed on the side of the casing, and the control circuit board is adjacent to one side of the partition, and the power supply circuit board is vertically arranged and installed inside the housing adjacent to the other side of the partition.

[0024] As Figures 1-4 shown, the inside of the housing is divided into three installation spaces from left to right, which are used to install the casing, the control circuit board, and the power supply circuit board in sequence. The power supply circuit board is electrically connected to the control circuit board, and the control circuit board is electrically connected to the driving motor inside the casing, so as to control the rotation of the driving motor. The driving motor then drives the track to move through the gear set and other transmission parts.

[0025] For the described short - type curtain motor structure, the cross - sectional shape of the outer shell 1 is a racetrack shape with arc - shaped ends and a straight middle section. The housing is circular, and the housing 8 and the power circuit board 5 are respectively arranged at the two racetrack - shaped ends of the outer shell. This can make the internal structure of the motor more compact, and can further reduce the volume and improve the aesthetics of the motor. At the same time, reinforcing ribs 12 are provided at the intersections of the arc - shaped section and the straight section of the racetrack - shaped outer shell 1. The reinforcing ribs opposite to the housing 8 extend along the inner wall of the arc - shaped section to form arc - shaped reinforcing ribs; while the reinforcing ribs 12 opposite to the power circuit board 5 can be strip - shaped or block - shaped, and a vertically - arranged reinforcing plate 13 is provided on the inner wall of the arc - shaped section opposite to the power circuit board 5. This is because the intersections of the arc - shaped section and the straight section of the racetrack - shaped structure are stress - concentration positions, where the force is large and the structural strength is low. Therefore, the structural strength of the outer shell can be effectively improved by setting the reinforcing ribs, and the safety and stability of the motor operation are ensured. Also, the reinforcing ribs 12 opposite to the power circuit board 5 are also vertically arranged. The adjacent side of this reinforcing rib and the partition 11 is a positioning groove 14. The side of the power circuit board 5 is arranged in the positioning groove, so as to position the power circuit board. Then, the power circuit board is clamped and fixed by the top cover and the base at the upper and lower ends, which can effectively improve the installation stability of the power circuit board. And a positioning strip 15 protruding towards the side of the control circuit board 4 is provided at the position opposite to the side of the control circuit board 4 inside the outer shell 1, which can also position the control circuit board. In addition, the height of the top surface of the partition 11 is lower than that of the control circuit board 4 and the power circuit board 5, so as to leave enough space for the electronic components connecting the control circuit board and the power circuit board to be arranged above the partition 11, thus ensuring electrical connection and structural compactness; at the same time, the electronic components are connection ends connected by plug - in. And the connection ends are in contact with the top surface of the partition 11. By using plug - in components, problems such as difficult connection and high space requirements caused by wire connection can be avoided. And making the top surface of the partition in contact with the plug - in components can support the plug - in components and improve the installation strength of the plug - in components, the control circuit board, and the power circuit board. In addition, the middle part of the partition 11 protrudes towards the control circuit board 4, and the side of the partition is bent towards the reinforcing rib 12, so that it can both cooperate with the reinforcing rib to position the power circuit board and leave a space for accommodating various electronic components on the power circuit board, making the space layout more compact.

[0026] For the described short - type curtain motor structure, there is a transmission component 9 for connecting the electric curtain track assembly and the gear set. The transmission component is installed on the top of the housing 8 and protrudes above the top surface of the outer shell 1, so that the transmission component is inserted into the transmission box installation groove of the electric curtain track assembly to form a connection; a protrusion is provided at the position on the top cover 6 opposite to the transmission component, so that it can also cover the transmission component and leave a through - hole for the transmission component to connect the electric curtain track assembly.

[0027] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
