[0036] Example 1

[0037] Combined with Figure 1-4 , this embodiment provides a rotary reciprocating motor, comprising:

[0038] A stator unit 1 and a rotor unit 2 that cooperate with each other;

[0039] A first limit block 31 and a second limit block 32 both connected to the stator unit 1;

[0040] A first limiting groove 41 formed between one end of the first limiting block 31 and one end of the second limiting block 32;

[0041] A first limiting rod 51 connected to the rotor unit 2;

[0042] A first trigger switch 61 connected to the first limit block 31;

[0043] A second trigger switch 62 connected to the second limit block 32;

[0044] A controller electrically connected to the stator unit 1, the first trigger switch 61 and the second trigger switch 62;

[0045] The first limiting rod 51 is movably located in the first limiting groove 41 .

[0046] Specifically, during operation, the controller controls the stator unit 1, thereby controlling the rotor unit 2 to rotate in a first direction. When the first limit rod 51 and the first trigger switch 61 are in contact, the first trigger switch 61 transmits a first trigger signal to the controller, and the controller controls the stator unit 1, thereby controlling the rotor unit 2 to rotate in a second direction. When the first limit rod 51 and the second trigger switch 62 are in contact, the second trigger switch 62 transmits a second trigger signal to the controller, and the controller controls the stator unit 1, thereby controlling the rotor unit 2 to rotate in the first direction again to achieve rotational reciprocating motion; when the first trigger switch 61 and / or the second trigger switch 62 fail, one end of the first limit block 31 and one end of the second limit block 32 facilitate the production of double-sided mechanical limiting of the first limit rod 51, thereby making the limiting reliability high.

[0047] The first limiting groove 41 is used to accommodate the first limiting rod 51 .

[0048] Further, such as Figure 2 , also includes:

[0049] A second limiting groove 42 formed between the other end of the first limiting block 31 and the other end of the second limiting block 32;

[0050] The second limiting rod 52 is connected to the rotor unit 2 and is movably located in the second limiting groove 42 .

[0051] Specifically, when the first trigger switch 61 and / or the second trigger switch 62 fails, the other end of the first limit block 31 and the other end of the second limit block 32 facilitate the double-sided mechanical limiting of the second limit rod 52, further improving the limiting reliability; the second limit groove 42 is used to accommodate the second limit rod 52.

[0052] Further, such as Figure 2 The first limiting rod 51 and the second limiting rod 52 are integrally formed and connected.

[0053] Specifically, the one-piece connection facilitates increasing the integrity of the first limiting rod 51 and the second limiting rod 52 .

[0054] Further, such as Figure 2 The cross-sectional shape of the first limiting rod 51 and the cross-sectional shape of the second limiting rod 52 are both non-rotational.

[0055] Specifically, the non-rotatable shape facilitates preventing the first limiting rod 51 and the second limiting rod 52 from rotating around the rotor unit 2 .

[0056] Further, such as Figure 2 The first limiting groove 41 and the second limiting groove 42 are arranged axially symmetrically with respect to the rotor unit 2 .

[0057] Specifically, the first limiting block 31 and the second limiting block 32 are axially symmetrically arranged with respect to the rotor unit 2 , so as to facilitate good force symmetry of the first limiting rod 51 and the second limiting rod 52 .

[0058] Further, such as Figure 2 , and also includes a planar portion 53 that passes through the first limiting rod 51 and the second limiting rod 52.

[0059] Specifically, the plane portion 53 located on the first limiting rod 51 facilitates good contact between the first limiting rod 51 and the first trigger switch 61 and the second trigger switch 62 ; the plane portion 53 located on the second limiting rod 52 facilitates preventing the second limiting rod 52 from rotating.

[0060] Further, such as Figure 2 The first limiting rod 51 includes a limiting part 1 511 and a limiting part 2 512 which are connected to each other. The limiting part 1 511 and the limiting part 2 512 are both connected to the rotor unit 2. The limiting part 1 511 and the limiting part 2 512 are both movably located in the first limiting groove 41. The limiting part 1 511 and the first limiting block 31 and the second limiting block 32 are correspondingly arranged. The limiting part 2 512 and the first trigger switch 61 and the second trigger switch 62 are correspondingly arranged.

[0061] Specifically, since the limit part 1 511 and the first limit block 31 and the second limit block 32 are all arranged correspondingly, the first limit block 31 and the second limit block 32 are used to produce bilateral mechanical limiting for the limit part 1 511; since the limit part 2 512 and the first trigger switch 61 and the second trigger switch 62 are all arranged correspondingly, the limit part 2 512 is used to trigger the first trigger switch 61 and the second trigger switch 62.

[0062] Further, such as Figure 4 , also includes:

[0063] A gear reducer 71, wherein an input end of the gear reducer 71 is connected to the rotor unit 2;

[0064] An output shaft 72 connected to the output end of the gear reducer 71;

[0065] The first limiting rod 51 is connected to the output shaft 72 .

[0066] Specifically, the gear reducer 71 is used to connect the rotor unit 2 and the output shaft 72, thereby facilitating speed reduction and increasing torque.

[0067] Further, such as Figure 4 , and also includes a shell 73, one end of the shell 73 is connected to the stator unit 1, the first limit block 31 and the second limit block 32 are both connected to the other end of the shell 73, and the gear reducer 71 is located in the shell 73.

[0068] Specifically, the housing 73 is used to protect the gear reducer 71 .

[0069] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
