[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A drive motor for rotating an electric children's stroller ornament includes a housing 1 and a connection port 2. An outer cover 3 is fixedly connected to the housing 1 on the outside of the connection port 2. A front plate 13 is fixedly connected to the outer cover 3. The front plate 13 includes an upper plate 1301 and a lower plate 1302. A sealing plate 6 is slidably connected to the inner surface of the upper plate 1301. The sealing plate 6 has a T-shaped structure, and an elastic component for maintaining the vertical position of the sealing plate 6 is provided on the outer surface of the outer cover 3.

[0025] Pulling the sealing plate 6 upward by lifting the ring 9 stretches the spring 8. At this time, the external connector can be inserted into the connection port 2 through the opening of the upper plate 1301. Then, align the wire harness on the connection port 2 with the inside of the semi-circular slot 12 and gradually release the sealing plate 6 until the sealing plate 6 is fitted onto the outside of the wire harness through the semi-circular slot 10. At this time, the front plate 13 and the outer cover 3 form a closed chamber on the outside of the connection between the external connector and the connection port 2, which improves the dustproof and waterproof performance of the drive motor. The spring 8 maintains the position of the sealing plate 6, and the sealing plate 6 restricts the position of the external connector by limiting the range of motion, thereby preventing the external connector from becoming loose from the connection port 2, thus improving the stability of the drive motor for the rotation of the electric children's stroller.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the outer cover 3 has two sets of symmetrically distributed side pieces 4 fixedly connected to its outer wall. The two sets of side pieces 4 are fixedly connected to the housing 1 by two sets of locking rods 5. The outer cover 3 is fixed to the housing 1 by the cooperation of the side pieces 4 and the locking rods 5. This ensures the stability of the position of the outer cover 3 and the convenience of disassembling and assembling the outer cover 3 and the housing 1. The outer cover 3 can be selected and disassembled according to the needs, thereby improving the convenience of using the drive motor of the electric children's car ornament rotation.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the elastic component includes an outer block 7 fixedly connected to the outer wall of the outer cover 3. A spring 8 is fixedly connected between the outer block 7 and the bottom of the horizontal end of the sealing plate 6, so as not to affect the vertical movement characteristics of the sealing plate 6, while maintaining the position of the sealing plate 6 through elastic force. The sealing plate 6 and the upper plate 1301 have semi-circular slot 10 and semi-circular slot 2 12 respectively on their opposite surfaces, and the semi-circular slot 10 and semi-circular slot 2 12 are vertically aligned. The interior of the semi-circular slot 10 and semi-circular slot 2 12 is filled with rubber pads 11 to fit the outline of the external wire harness. With the rubber pads 11, the tightness of the connection with the wire harness can be ensured. A lifting ring 9 is fixedly connected to the top of the sealing plate 6 to facilitate the pulling of the sealing plate 6. The outer cover 3 and the front plate 13 are integrally formed to ensure the structural strength between the two. The outer wall of the vertical end of the sealing plate 6 is slidably connected to the inner wall of the upper plate 1301 through a rectangular groove to ensure the stability of the vertical movement of the sealing plate 6.

[0028] Working principle: By pulling the sealing plate 6 upward by the lifting ring 9, the spring 8 is stretched. At this time, the external connector can be inserted into the connection port 2 through the opening of the upper plate 1301. Then, the wire harness on the connection port 2 is aligned with the inside of the semi-circular slot 12. The sealing plate 6 is gradually released until it is fitted onto the outside of the wire harness through the semi-circular slot 10. At this time, the front plate 13 and the outer cover 3 form a closed chamber on the outside of the connection between the external connector and the connection port 2, which improves the dustproof and waterproof performance of the drive motor. The spring 8 maintains the position of the sealing plate 6, and the sealing plate 6 restricts the position of the external connector by limiting the range of motion, thereby preventing the external connector from loosening with the connection port 2. This improves the stability of the drive motor of the electric children's stroller. The outer cover 3 is fixed to the housing 1 by the cooperation of the side plate 4 and the locking rod 5. This ensures the stability of the outer cover 3 and the ease of disassembly and assembly of the outer cover 3 and the housing 1. The outer cover 3 can be selected and disassembled according to the needs, thereby improving the ease of use of the drive motor of the electric children's stroller.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
