[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a motor protective housing structure for an electric folding device, referring to... Figure 1 and Figure 2 It includes a motor cover 1, a motor 2 and an outer cover 3. The motor 2 is installed in the outer cover 3. The motor cover 1 and the outer cover 3 are detachably connected to form a complete protective shell to protect the motor 2.

[0036] The outer cover 3 includes a base 31, a top plate 32, and multiple first side plates 33. The multiple first side plates 33 are vertically fixed to the base 31 and are interconnected. The top plate 32 is fixedly connected to the end of the first side plates 33 away from the base 31. The top plate 32 is parallel to the base 31 and, together with the multiple first side plates 33, forms a first mounting cavity 34 for accommodating the motor 2. The base 31, top plate 32, and multiple first side plates 33 are integrally formed. In this embodiment, three first side plates 33 are provided, and the included angle between two adjacent first side plates 33 is 120°.

[0037] A circular mounting hole 311 is provided on the base 31. The mounting hole 311 is located inside the first mounting cavity 34, and the axis of the mounting hole 311 is perpendicular to the plane of the base 31. The rotating shaft of the motor 2 extends out from the mounting hole 311 and is used to cooperate with the gear transmission below the base 31 to provide driving force for the electric folding device.

[0038] A circular limiting block 321 protrudes from the top plate 32, located at the center of the end of the top plate 32 closest to the motor cover 1; a circular locking hole 322 is formed at the center of the limiting block 321. A circular locking protrusion 21 protrudes from the end of the motor 2 away from the rotating shaft, with the axis of the locking protrusion 21 aligned with the axis of the rotating shaft of the motor 2. When the motor 2 is installed in the first mounting cavity 34, the locking protrusion 21 extends from below the top plate 32 and engages with the locking hole 322, effectively limiting the installation position of the upper end of the motor 2, reducing vibration during motor 2 operation, making the motor 2 more stable during operation, and enhancing overall stability.

[0039] Two snap-fit ​​strips 323 are provided at one end of the top plate 32 near the outer cover 3, and the two snap-fit ​​strips 323 are respectively located at both ends of the limiting block 321; in this embodiment, the included angle between the two snap-fit ​​strips 323 is 120°. In order to further enhance the deformation resistance of the top plate 32, a reinforcing rib 324 is also provided on the top plate 32. The reinforcing rib 324 extends from the side wall of the limiting block 321 to the periphery of the top plate 32, and the included angle between the reinforcing rib 324 and the two snap-fit ​​strips 323 is equal, that is, the included angle between the reinforcing rib 324 and the snap-fit ​​strips 323 is 60°. In this embodiment, the limiting block 321, the snap-fit ​​strips 323 and the reinforcing rib 324 are integrally formed.

[0040] Reference Figure 2 and Figure 3 The motor cover 1 includes a cover plate 11 and a plurality of second side plates 12. The plurality of second side plates 12 are respectively vertically fixed to the periphery of the cover plate 11 and connected to each other to form a second mounting cavity 13 for accommodating the motor 2. In this embodiment, three second side plates 12 are provided, and the included angle between two adjacent second side plates 12 is 120°; the cover plate 11 and the plurality of second side plates 12 are integrally formed.

[0041] The first side plate 33 has a first mating part 331 at the end near the motor cover 1, and the second side plate 12 has a second mating part 121 at the end near the outer cover 3. The shapes and positions of the first mating part 331 and the second mating part 121 correspond one-to-one. When the motor cover 1 and the outer cover 3 are fastened together, the end of the second side plate 12 away from the cover plate 11 abuts against the top of the base 31, and the first mating part 331 abuts against the second mating part 121, ensuring the precise alignment of the motor cover 1 and the outer cover 3 when fastened together, thereby forming a complete protective shell.

[0042] A circular cover block 111 protrudes from one end of the cover plate 11 near the outer cover 3, and the plane of the end of the cover block 111 near the second mounting cavity 13 is higher than the plane of the cover plate 11. When the motor cover 1 and the outer cover 3 are fastened together, the cover block 111 extends from above the top plate 32 and engages in the engagement hole 322, thereby achieving precise positioning of the cover plate 11 and the top plate 32.

[0043] The two ends of the cover block 111 are respectively provided with first buckles 112. The first buckles 112 are L-shaped. The two first buckles 112 are respectively connected to two snap-fit ​​strips 323, which further enhances the connection stability between the motor cover 1 and the top of the outer cover 3 and effectively reduces the situation of the cover plate 11 and the top plate 32 separating due to vibration.

[0044] A fixing strip 113 is fixedly connected to the end of the cover plate 11 away from the outer cover 3. The fixing strip 113 is located at the end of the second side plate 12 near the second mounting cavity 13. The length of the fixing strip 113 is longer than the length of the second side plate 12, and a second buckle 114 is provided outward at the end of the fixing strip 11 away from the cover plate 11. A fixing groove 312 is provided at the end of the base 31 near the motor cover 1. The fixing strip 113 is engaged in the fixing groove 312 by the second buckle 114, thereby realizing the fixed connection between the motor cover 1 and the base 31.

[0045] During installation, the second buckle 114 is moved toward the second mounting cavity 13 and inserted into the fixing groove 312. The fixing strip 113 has a force toward the second side plate 12, so that the second buckle 114 and the groove wall of the fixing groove 312 are engaged with each other, thereby achieving a stable connection between the motor cover 1 and the bottom of the outer cover 3.

[0046] The implementation principle of the motor protective shell structure of the electric folding device disclosed in this application is as follows: the rotating shaft of the motor 2 is inserted into the mounting hole 311, and the snap-fit ​​protrusion 21 is snapped into the snap-fit ​​hole 322, thereby fixing the motor 2 in the first mounting cavity 34 of the outer cover 3; then the second snap 114 of the motor cover 1 is inserted into the fixing groove 312, so that the first mating part 331 and the second mating part 121 abut against each other; finally, the cover assembly block 111 is snapped into the snap-fit ​​hole 322 from the upper end of the top plate 32, and the two first snaps 112 are respectively snapped into the snap-fit ​​strip 323, thereby realizing the assembly of the motor cover 1 and the outer cover 3, and the motor 2 is firmly fixed in the protective shell; when the protective shell needs to be disassembled, the motor cover 1 can be lifted up to achieve quick separation of the motor cover 1 and the outer cover 3, which is convenient to disassemble and simple to operate.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
