Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1-3 As shown, this utility model provides a connecting bracket for a three-moving motor, including an integrally formed bracket body 1. The bracket body 1 is provided with two baffles 2 formed by bending upwards and two crossbeams 3 located between and connecting the two baffles 2. A moving part groove 11 for moving the inner moving part 4 is provided between the two crossbeams 3. At least one of the crossbeams 3 is provided with a connecting block 31 formed by bending upwards, and the connecting block 31 is provided with a positioning hole 313. In the application of a three-movement motor, the two outer movers need to swing synchronously. In order to ensure that the swing frequency of the two outer movers is consistent, reduce the resistance of the inner mover 4 swing, and improve the installation efficiency, the two outer movers are connected to the same connecting bracket. However, the existing connecting bracket has a relatively complex structure, resulting in low processing efficiency and high production cost. Therefore, this utility model improves the connecting bracket. In this embodiment, the connecting bracket is made of a thin sheet metal material through cutting, stamping, and bending processes, so that the main body 1 of the bracket after forming is a whole. The structure is simple and the overall weight is lighter, making the swing of the mover smoother and more accurate.

[0027] Specifically, the sheet metal is a galvanized iron sheet or stainless steel sheet with a uniform thickness of 0.5 to 2.5 mm, preferably 0.8 mm.

[0028] Specifically, the support body 1 is provided with two baffles 2 formed by bending upwards, and each of the two baffles 2 is provided with a positioning platform 21 formed by stamping. The two positioning platforms 21 are arranged opposite to each other. The positioning platform 21 is used to limit the spring and prevent the spring from deviating. Due to the elastic force of the spring itself, the inner moving part 4 can be kept in balance when it moves back and forth in the moving part groove 11, providing a certain buffering effect so as to prevent the inner moving part 4 from colliding with the support body 1 when subjected to external interference. In this embodiment, the positioning platform 21 is formed by stamping the support body 1, which not only has a limiting function, but also saves raw materials and reduces production costs.

[0029] Furthermore, the support body 1 is also provided with two crossbeams 3 connected to both ends of the two baffles 2. There is a cavity between the two crossbeams 3 and the two baffles 2, forming the moving part groove 11, so that the inner moving part 4 swings in the moving part groove 11, while the two outer moving parts are connected to the two crossbeams 3 and swing synchronously. At least one of the crossbeams 3 is provided with a connecting block 31 formed by bending upwards. The connecting block 31 is located at the middle position of the crossbeam 3 to ensure that the weight of the two ends of the support body 1 is balanced. The connecting block 31 is provided with a positioning hole 313, which is used to install the outer swing shaft of the outer moving part. Compared with the traditional technology of setting an additional swing column on the connecting support, the structure of setting the connecting block 31 and the positioning hole 313 on the support body 1 in this embodiment is simpler and saves more materials. The connecting block 31 on one of the crossbeams 3 includes a first bending portion 311 and a second bending portion 312. The second bending portion 312 is disposed toward the other crossbeam 3. The positioning hole 313 is disposed on the second bending portion 312. The first bending portion 311 and the two baffles 2 are perpendicular to the two crossbeams 3, while the second bending portion 312 is disposed parallel to the crossbeam 3. That is, the connecting block 31 is formed by two bends, each bend being 90°.

[0030] Furthermore, such as Figure 4 As shown, the two crossbeams 3 are provided with a plurality of screw holes 32, which are also integrally cut. Below the two crossbeams 3, an external connector 5, an external magnetic yoke 6, and an external magnet 7 fixedly connected to the external magnetic yoke 6 are also provided in sequence. Both the external connector 5 and the external magnetic yoke 6 are provided with fixing holes 51 corresponding to the screw holes 32. During installation, the screw holes 32 correspond to the fixing holes 51, and screws are sequentially passed through the screw holes 32 of the crossbeam 3 and connected to the fixing holes 51 of the external connector 5 and the external magnetic yoke 6, thereby fixing the three together. This makes the assembly more convenient and efficient. In this embodiment, there are two screw holes 32 on the same crossbeam 3, respectively located at both ends of the crossbeam 3. In application, a stator that generates electromagnetic induction with the external magnet 7 is also provided below the external magnet 7. Under the action of electromagnetic induction, the external magnet 7 will move back and forth, thereby driving the mover to move back and forth.

[0031] Furthermore, such as Figure 4 , Figure 5As shown, the two crossbeams 3 are also provided with downwardly pressed protrusions 33, which are disposed between the two screw holes 32. The outer connector 5 is provided with a groove 52 that matches the protrusions 33. The protrusions 33 and the grooves 52 engage to prevent the crossbeams 3 and the outer connector 5 from shifting, further enhancing the stability of the connection between the support body 1 and the outer actuator. In this embodiment, there are also two protrusions 33 under the same crossbeam 3.

[0032] Furthermore, each end of the two baffles 2 is provided with a positioning groove 12 at the connection point with the two crossbeams 3. The positioning groove 12 is rectangular, and after bending, both the baffles 2 and the crossbeams 3 have a portion of the groove of the positioning groove 12. That is, in the bending process, the bending point is set in the positioning groove 12, so that after bending, both the baffles 2 and the crossbeams 3 have a portion of the groove. During installation, other components can pass through from the bottom of the crossbeams 3 and the side of the baffles 2, making assembly more convenient.

[0033] Preferably, such as Figure 6 As shown, the bottom end of the baffle 2 is provided with two inclined sides 22 at the connection between it and the moving part groove 11. The two inclined sides 22 are inclined inward and upward from both ends of the baffle 2, so that the bottom end of the baffle 2 forms a clearance opening 23. When the inner moving part 4 moves in the positioning groove 12, part of it will pass through the bottom end of the baffle 2. Therefore, the setting of the clearance opening 23 can ensure that the inner moving part 4 has enough room to move during operation and will not collide with the baffle 2.

[0034] Preferably, the top edge of the baffle 2 is designed with an arc shape, which makes the edge of the baffle 2 smoother, safer to install, and more aesthetically pleasing.

[0035] The innovation of this utility model lies in the provision of an integrally formed bracket body that connects to the two external movers, which simplifies the entire motor structure, makes it lighter, and greatly improves assembly efficiency. In terms of processing, the bracket body is first cut to form positioning grooves, mover grooves, and screw holes for assembly and positioning, then stamped to form positioning platforms and protrusions for limiting and fixing, and finally bent to form baffles and connecting blocks. The processing is convenient, thereby improving production efficiency.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
