[0002] At present, most of the existing electric curtains drive the curtain motor by directly connecting the electric wire to the socket. However, when a power outage or other conditions occur, users cannot use the electric curtain; for this reason, curtain motors with batteries have emerged on the market. However, most of the existing curtain motors are connected to the battery by using an external wire or by setting the battery inside the motor housing. However, using the external wire method affects the aesthetics and has potential safety hazards; and setting the battery inside the motor housing is not convenient for replacing and maintaining the battery, and the loading and unloading efficiency of the battery is relatively low. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems and provide a clamping structure between a motor and a lithium battery.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A clamping structure between a motor and a lithium battery, including a motor housing and a battery housing. One end face of the motor housing is provided with a positioning groove, and a male terminal or a female terminal is arranged inside the positioning groove. One end face of the battery housing is provided with a positioning convex part inserted into the positioning groove and capable of being radially movable relative to the positioning groove. A female terminal or a male terminal is arranged on one side of the positioning convex part. A clamping and positioning structure is arranged between the positioning convex part and the positioning groove, which can make the male terminal and the female terminal be inserted into each other and axially position the positioning convex part and the positioning groove when the positioning convex part moves radially relative to the positioning groove. And an elastic clamping structure capable of making the side part of the positioning convex part and the side part of the positioning groove abut against each other is further arranged between the positioning convex part and the positioning groove. Through the elastic clamping structure, when the clamping and positioning structure is clamped and connected, the connection stability between the battery housing and the motor housing is further improved, and the connection effect is ensured.

[0005] In the above-mentioned clamping structure between a motor and a lithium battery, the positioning groove is quadrilateral. A male terminal is arranged in the positioning groove, and the male terminal is located inside the positioning groove and close to one side of the positioning groove. A female terminal corresponding to the male terminal is arranged on one side of the positioning convex part. The size of the positioning convex part is smaller than that of the positioning groove, and the male terminal and the female terminal are inserted and connected to ensure the power supply effect of the motor in the battery housing.

[0006] In the above-mentioned clamping structure between a motor and a lithium battery, the length of the positioning convex part is smaller than that of the positioning groove, and the height of the positioning convex part is not greater than the depth of the positioning groove, which is convenient for the positioning convex part to be arranged in the positioning groove and improves the installation efficiency.

[0007] In the above-mentioned clamping structure between the motor and the lithium battery, the clamping and positioning structure includes two groups of clamping grooves respectively arranged on two opposite sides of the positioning groove.

There are elastic arms made of elastic materials in the deformation notches, and one side of the elastic arms abuts against both sides of the clamping groove. Through the deformation notches, it is convenient for users to press the elastic arms to ensure that the elastic arms can be elastically abutted on the sides of the clamping groove, further improving the connection effect between the battery housing and the motor housing.

[0011] In the above-mentioned clamping structure between the motor and the lithium battery, a radial guiding component is arranged between the positioning convex part and the positioning groove. Through the radial component, the sliding direction of the positioning convex part in the positioning groove can be ensured, and the insertion effect between the male terminal and the female terminal can also be ensured.

[0012] In the above-mentioned clamping structure between a motor and a lithium battery, the radial guiding component includes a guiding groove provided on the upper side of one end of the positioning convex portion away from the female terminal. The guiding groove extends along the length direction of the positioning convex portion, and one end of the guiding groove forms an opening on the side of the positioning convex portion. The width of the end of the guiding groove with the opening is smaller than the width of the other end. A guiding block slidably arranged in the guiding groove is provided in the positioning groove. The opening facilitates the sliding arrangement of the guiding block in the guiding groove, thereby improving the installation efficiency of the guiding block.

[0013] In the above-mentioned clamping structure between a motor and a lithium battery, an elastic top bead protruding from the bottom of the guiding groove is provided in the guiding groove, and a limiting shallow groove cooperating with the elastic top bead is provided on the guiding block.
