The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Please see Figures 1-2 As shown, Figure 1 This is a schematic diagram of the structure of one embodiment of the encoder fixing component provided in this application; Figure 2 This is a front view schematic diagram of an embodiment of the motor rear end cover provided in this application. The encoder fixing assembly 100 of this embodiment includes a motor rear end cover 10 and a positioning member 20.

[0029] The motor rear end cover 10 has a through hole (not shown in the figure) for accommodating one end of the motor shaft 40.

[0030] Optionally, the through hole is a circular through hole, and one end of the motor shaft 40 passes through the through hole and is installed in the rear end cover 10 of the motor.

[0031] The positioning element 20 is disposed on the rear end cover 10 of the motor. The positioning element 20 is disposed around the through hole and is integrally disposed with the rear end cover 10 of the motor. The positioning element 20 is used to install the circuit board 30 of the encoder.

[0032] In some embodiments, the positioning member 20 and the motor rear end cover 10 are integral structures made by the same processing technology (such as casting). In this case, the positioning member 20 is disposed on the motor rear end cover 10 and the positioning member 20 is disposed around the through hole, that is, the positioning member 20 is disposed around the motor shaft 40, so as to ensure the coaxiality and positional accuracy of the encoder circuit board 30 mounted on the positioning member 20 and the motor shaft 40.

[0033] In this embodiment, by integrating the positioning element 20 with the rear end cover 10 of the motor, a precise and stable mounting position can be provided for the encoder circuit board 30. Compared with the existing mounting method, this application greatly reduces the number of parts and lowers the cost; and by surrounding the positioning element 20, the protection level of the encoder is improved.

[0034] According to some embodiments of this application, the positioning member 20 includes an annular boss, the center of which overlaps with the center of the through hole.

[0035] In some embodiments, the positioning member 20 is an annular boss that is not completely closed. The annular boss is arranged around the through hole, and the center of the annular boss overlaps with the center of the through hole. At this time, the annular boss and the through hole of the motor rear end cover 10 are concentrically arranged. When the motor shaft 40 passes through the through hole into the motor rear end cover 10, the annular boss, the through hole and the motor shaft 40 are coaxially arranged.

[0036] like Figure 2 As shown, the annular boss surrounding the outside of the through hole is C-shaped, meaning the annular boss is not completely closed, and the motor shaft 40, the through hole, and the annular boss are coaxially arranged.

[0037] In some embodiments, the positioning member 20 is a fully closed annular boss, which surrounds the through hole and the center of the annular boss overlaps with the center of the through hole. At this time, the annular boss and the through hole of the motor rear end cover 10 are concentrically arranged. When the motor shaft 40 passes through the through hole into the motor rear end cover 10, the annular boss, the through hole and the motor shaft 40 are coaxially arranged.

[0038] In this embodiment, by setting an annular boss, a relatively closed environment can be formed when the encoder circuit board 30 is installed on the annular boss, which improves the sealing performance between the motor rear end cover 10 and the encoder, thereby improving the protection level of the entire motor system.

[0039] According to some embodiments of this application, at least two positioning parts 21 are provided on the annular boss, and the at least two positioning parts 21 are spaced apart. The encoder circuit board 30 is fixed on the annular boss through the positioning parts 21.

[0040] Alternatively, the encoder circuit board 30 may be fixed to the annular boss by means including but not limited to screws, clips, or pins.

[0041] In some embodiments, the annular boss is provided with two positioning parts 21, which can be symmetrically arranged so that the encoder circuit board 30 is evenly stressed when it is fixed on the annular boss by the two positioning parts 21.

[0042] In some embodiments, the annular boss is provided with three positioning parts 21, which are spaced apart and the distance between the three positioning parts 21 is equal, so that when the encoder circuit board 30 is fixed on the annular boss through the three positioning parts 21, the force is uniform.

[0043] like Figure 2 As shown, the annular boss has three positioning parts 21, which can form an equilateral triangle.

[0044] This embodiment ensures the stable fixing of the encoder circuit board 30 on the annular boss by setting at least two positioning parts 21 on the annular boss, reducing the loosening or displacement that may be caused by single-point fixing.

[0045] According to some embodiments of this application, the side wall of the annular boss is also provided with an opening for accommodating the light source of the encoder (not shown in the figure) so that the light source of the encoder is fixed on the rear end cover 10 of the motor.

[0046] In some embodiments, when the encoder is a photoelectric encoder, an opening is provided on the side wall of the annular boss to form an incompletely closed annular boss; the encoder circuit board 30 is fixed on the annular boss, and the encoder's light source is fixed on the motor rear end cover 10; at this time, the opening of the annular boss is used to accommodate the encoder's light source.

[0047] According to some embodiments of this application, the encoder fixing assembly 100 further includes at least two fixing members 50, which are correspondingly disposed with at least two positioning portions 21. Each positioning portion 21 includes a mounting hole, through which the fixing members 50 fix the encoder circuit board 30 to the annular boss.

[0048] Among them, the fastener 50 includes, but is not limited to, screws; the mounting hole includes, but is not limited to, threaded hole.

[0049] In some embodiments, the annular boss has two mounting holes, and the encoder circuit board 30 has two corresponding mounting holes. Two fasteners 50 are used to fix the encoder circuit board 30 onto the annular boss through the mounting holes of the circuit board 30 and the mounting holes of the annular boss, respectively.

[0050] In some embodiments, the annular boss has three mounting holes, and the encoder circuit board 30 has correspondingly three mounting holes. Three fasteners 50 pass through the mounting holes of the circuit board 30 and the mounting holes of the annular boss, respectively, to fix the encoder circuit board 30 to the annular boss. For example, as... Figure 1 As shown, the encoder circuit board 30 is fixed to the annular boss by three screws.

[0051] According to some embodiments of this application, see Figures 3-5 As shown, Figure 3 This is a schematic diagram of another embodiment of the encoder fixing component provided in this application; Figure 4 yes Figure 3 A front view schematic diagram of another embodiment of the encoder fixing assembly; Figure 5 This is a schematic diagram of another embodiment of the motor rear end cover provided in this application. The positioning member 20 in this embodiment includes at least two positioning bosses, which are arranged around the through hole.

[0052] This embodiment, by setting at least two positioning bosses, can ensure that the circuit board 30 is subjected to uniform force on the positioning member 20, reduce the displacement or damage of the circuit board 30 caused by mechanical stress and vibration, and ensure that the encoder maintains a stable working state during motor operation.

[0053] According to some embodiments of this application, each positioning boss is provided with a positioning part 21, and the encoder circuit board 30 is fixed to the positioning boss through the positioning part 21.

[0054] In some embodiments, the positioning member 20 includes at least two positioning bosses, each positioning boss having a positioning part 21; at this time, with at least two positioning parts 21, the encoder circuit board 30 is fixed to at least two positioning bosses by at least two positioning parts 21.

[0055] According to some embodiments of this application, the encoder fixing assembly 100 further includes at least two fixing members 50, which are correspondingly disposed with at least two positioning bosses. The positioning part 21 includes mounting holes, through which the fixing members 50 fix the encoder circuit board 30 to the at least two positioning bosses.

[0056] Among them, the fastener 50 includes, but is not limited to, screws; the mounting hole includes, but is not limited to, threaded hole.

[0057] In some embodiments, the positioning member 20 includes at least two positioning bosses, each positioning boss having a mounting hole, and the encoder circuit board 30 having at least two corresponding mounting holes. The encoder circuit board 30 is fixed to the at least two positioning bosses by at least two fixing members 50 passing through the mounting holes of the circuit board 30 and the mounting holes of the positioning bosses.

[0058] According to some embodiments of this application, the positioning member 20 includes three positioning bosses, which are arranged around the through hole, and the distance between the three positioning bosses is equal. For example, Figure 4 As shown, there are three equidistant positioning bosses arranged around the through hole.

[0059] This embodiment further improves the stability of encoder installation by setting three equidistant positioning bosses.

[0060] Another embodiment of this application provides an electronic device, including a motor and the encoder fixing assembly 100 of the above embodiments.

[0061] Optionally, the motor is a rotary motor. The electronic equipment includes, but is not limited to, automotive electronic equipment, smart home equipment, or industrial equipment.

[0062] By integrating the positioning element 20 with the rear end cover 10 of the motor, this application provides a precise and stable mounting position for the encoder circuit board 30. Compared with existing mounting methods, this application greatly reduces the number of parts and lowers costs; and by surrounding the positioning element 20, the protection level of the encoder is improved.
