[0031] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the specification and drawings are only for clearly describing a certain embodiment, and do not mean that they are essential components and / or sequences.

For the terms "connection" and "coupling" used in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0033] The encoder assembly can be used to monitor position information such as the rotational speed and angle of a motor. The encoder assembly is usually provided with a bracket for mounting a circuit board. The bracket is installed inside the encoder cover to fix the circuit board inside the encoder cover. Due to the setting of the bracket, the overall volume of the encoder assembly is relatively large, and an encoder cover with a relatively large installation space inside needs to be provided, which is not conducive to the miniaturization design of the product.

[0034] To address the above problems, this application provides an encoder assembly and a motor to optimize the structural design, thereby reducing the cost and overall volume of the encoder assembly.

[0035] This embodiment provides an encoder assembly for a motor to monitor position information such as the rotational speed and angle of the motor. Refer to Figures 1 - 7 As shown, the encoder assembly 100 provided in this embodiment includes a circuit board 20 and an electrical connection mechanism 30.

[0036] The electrical connection mechanism 30 includes a conductive fixing component 31 and a connector 32. The connector 32 is fixedly arranged on the encoder cover 10. One end of the conductive fixing component 31 is electrically connected to the connector 32, and the other end of the conductive fixing component 31 is electrically connected to the circuit board 20 to fix the circuit board 20 on one side of the connector 32.

[0037] In this embodiment, the encoder cover 10 is the mounting structure of this encoder assembly 100. The encoder cover 10 has a receiving cavity 11. One end of the conductive fixing component 31 is electrically connected to the connector 32, and when the circuit board 20 is fixed on one side of the connector 32, the circuit board 20 is located inside the receiving cavity 11, thereby fixing the circuit board 20 inside the encoder cover 10.

[0038] As Figure 1As shown, an encoder rotor 40 is further provided inside the accommodation cavity 11. The motor 200 includes an encoder cover 10, an encoder rotor 40, and a motor body 50. The motor body 50 is composed of a stator (not shown in the figure) and a rotor 51. The rotating shaft 52 of the rotor 51 is connected to the center of the encoder rotor 40, so that the encoder rotor 40 can rotate synchronously with the rotor 51 through the rotating shaft 52. A photodetector 21 is provided on the circuit board 20. A plurality of grating holes (not shown in the figure) surrounding the center of the encoder rotor 40 are provided on the encoder rotor 40. The plurality of grating holes are arranged in the radial direction of the encoder rotor 40. During the rotation of the encoder rotor 40 with the rotor 51 through the rotating shaft 52, the photodetector 21 can detect the light passing through the grating holes. The photodetector 21 can output corresponding pulse signals under the action of the processor, and the rotational speed and angular position information of the current motor can be reflected by calculating the number of pulses output per unit time (for example, second, s).

[0039] In an embodiment of the present application, a flange 12 is further provided on the encoder cover 10, and the flange 12 is connected to the motor body 50 of the motor 200. In a preferred embodiment, a first bolt hole 121 is provided on the flange 12, and a first threaded hole is provided at a preset position of the motor body 50. The encoder cover 10 is fixed to the motor body 50 by passing a first bolt through the first bolt hole 121 and screwing it into the first threaded hole.

[0040] It can be understood that both ends of the conductive fixing component 31 are electrically connected to the connector 32 and the circuit board 20 respectively to indirectly electrically connect the connector 32 and the circuit board 20. The connector 32 can be connected to a motor control device (such as a driver) through structures such as wires, so as to transmit the collected position information to the motor control device, thereby more accurately controlling the motor 200. Since one end of the conductive fixing component 31 is used to connect to the connector 32, the conductive fixing component 31 can be fixed on the encoder cover 10, and the circuit board 20 is connected to the other end of the conductive fixing component 31, so that the circuit board 20 can be fixed inside the accommodation cavity 11 of the encoder cover 10. Thus, the conductive fixing component 31 has the function of electrically connecting the circuit board 20 and the connector 32, and can also fix the circuit board 20. Compared with the related art, there is no need to provide a bracket, which can reduce costs, reduce the space of the accommodation cavity 11 of the encoder cover 10, and reduce the overall volume of the present encoder assembly 100.

[0041] It should be noted that since the conductive fixing component 31 needs to have both conductive and fixing functions, in one embodiment, the conductive fixing component 31 can be composed of an insulating shell wrapping a conductive member of an electrical connector. The insulating shell can be made of a high-strength injection molding material. The conductive member can electrically connect the circuit board 20 and the connector 32. The insulating shell can endow the conductive fixing component 31 with a certain strength, so as to fix the circuit board 20 inside the accommodating cavity 11 of the encoder cover 10. In another embodiment, the conductive fixing component 31 can directly adopt a conductive member with strength, and can also fix the circuit board 20 in the accommodating cavity 11 of the encoder cover 10.

[0042] As Figures 2 - 6 shown, mounting holes 13 are provided on the encoder cover 10, second threaded holes 131 are provided around the mounting holes 13, through holes are provided on the connector 32, and the second bolts 33 pass through the through holes and are screwed into the second threaded holes 131 to fix the connector 32 on the outer wall of the encoder cover 10. And the conductive fixing component 31 is connected to the connector 32 through the mounting holes 13.

[0043] As one of the embodiments of the conductive fixing component 31, referring to Figures 3 - 7 shown, the conductive fixing component 31 includes a conductive fixing connector 311 and a plug 312. One end of the conductive fixing connector 311 is used for electrically connecting to the connector 32, and the other end of the conductive fixing connector 311 is fixedly connected to the plug 312. The circuit board 20 is provided with a first socket 22, and the plug 312 is used for plugging into the first socket 22.

[0044] It can be understood that the conductive fixing connector 311 can have a certain strength and has a conductive function, so that after the plug 312 is plugged into the first socket 22, the connector 32 and the circuit board 20 can be electrically connected through the conductive fixing connector 311.

[0045] As Figure 7 shown, a plurality of first connection terminals 221 are provided on the inner side wall of the first socket 22. As Figure 5 and Figure 6 shown, a plurality of second connection terminals 313 are provided on the outer side wall of the plug 312. The plurality of second connection terminals 313 and the plurality of first connection terminals 221 are respectively in one-to-one correspondence. The plug 312 is plugged into the first socket 22 so that the corresponding first connection terminals 221 and the second connection terminals 313 are electrically connected. Through the electrical connection of the corresponding first connection terminals 221 and the second connection terminals 313, the other end of the conductive fixing connector 311 can be electrically connected to the circuit board 20.

[0046] In a preferred embodiment, the first connection terminals 221 and the second connection terminals 313 can be made of one or a mixture of materials such as iron, aluminum, copper, etc. to endow them with conductivity.

[0047] In this application, when the plug 312 is inserted into the first socket 22, the first socket 22 is in interference fit connection with the end where the plug 312 is inserted, so as to fixedly connect the circuit board 20 through the interference fit between the first socket 22 and the plug 312.

[0048] In order to enable the conductive fixing connector 311 to have strength and conductive function, as Figure 5 and Figure 6 shown, the conductive fixing connector 311 in this embodiment includes a rigid housing 3111 and a plurality of electrical connectors (not shown in the figure). The plurality of electrical connectors are arranged inside the rigid housing 3111, and both ends of the plurality of electrical connectors can be exposed outside the rigid housing 3111. The connector 32 includes a connector housing 321 and a plurality of third connection terminals 322. A through hole is provided on the connector housing 321, that is, the second bolt 33 can pass through the through hole and then be screwed into the second threaded hole 131 to fix the connector 32 on the outer wall of the encoder cover 10. The plurality of third connection terminals 322 are arranged on the connector housing 321, and the plurality of electrical connectors correspond to the plurality of third connection terminals 322 one by one. One end of the rigid housing 311 is arranged inside the encoder cover 10, that is, the rigid housing 311 is connected to the connector housing 321 through the mounting hole 131. For example, the rigid housing 311 can be in a tight fit with the mounting hole 131. After the rigid housing 311 is connected to the connector housing 321 through the mounting hole 131, one end of the electrical connector can be connected to the third connection terminal 322, and the plug 312 is arranged at the other end of the rigid housing 311, so that the other end of the electrical connector is connected to the second connection terminal 313 on the plug 312.

[0049] The rigid housing 311 has a certain structural strength. After the plug 312 is inserted and connected to the first socket 22, the circuit board 20 can be fixed inside the receiving cavity 11 through the strength provided by the rigid housing 311.

[0050] In some embodiments, in order to make the product integrated and facilitate the production of the product, the rigid housing 311 and the connector housing 321 can be integrally formed, for example, by injection molding in an integral injection molding manner, so that the rigid housing 311 has insulation.

[0051] In this embodiment, multiple first connection terminals 221 are non-uniformly distributed on opposite side walls of the first socket 22, and multiple second connection terminals 313 are non-uniformly distributed on opposite side surfaces in the circumferential direction of the plug 312. For example, if seven first connection terminals 221 and seven second connection terminals 313 are provided, four first connection terminals 221 and three first connection terminals 221 are respectively provided on opposite side walls of the first socket 22, and four second connection terminals 313 and three second connection terminals 313 are respectively provided on opposite side surfaces in the circumferential direction of the plug 312. When the plug 313 is inserted into the first socket 22, the anti-fooling function can be achieved through the multiple first connection terminals 221 and multiple second connection terminals 313 in the non-uniform setting, so that the corresponding first connection terminals 221 and second connection terminals 313 can be connected to each other.

[0052] As one embodiment of the conductive fixing component 31, refer to Figures 8 - 10 and Figure 13 As shown, the conductive fixing component 31 includes multiple hard steel needles 314. One end of the multiple hard steel needles 314 is used for fixedly connecting with the connector 32. The circuit board 20 is provided with multiple second sockets 23. The multiple second sockets 23 respectively correspond to the multiple hard steel needles 314 one by one. The other ends of the multiple hard steel needles 314 are respectively inserted into the multiple second sockets 23, so that the hard steel needles 314 electrically connect the circuit board 20 and the connector 32 through the plug-in connection with the second sockets 23.

[0053] After the other end of the hard steel needle 314 is inserted into the second socket 23, to improve the firmness of the connection between the hard steel needle 314 and the second socket 23, refer to Figure 11 and Figure 12 As shown, multiple conductive clamping structures 24 are provided in the second socket 23. Among them, Figure 11 and Figure 12 exemplarily show a schematic diagram of setting one of the conductive clamping structures 24 in the second socket 23. The multiple conductive clamping structures 24 respectively correspond to the multiple hard steel needles 314 one by one, that is, the other ends of the multiple hard steel needles 314 are respectively inserted into the multiple conductive clamping structures 24 of the second socket 23, and the conductive clamping structure 24 is used for clamping and fixing the other end of the hard steel needle 314.

[0054] Here, it should be noted that the conductive clamping structure 24 is electrically connected to the circuit board 20. While clamping and fixing the hard steel needle 314, the conductive clamping structure 24 can electrically connect the hard steel needle 314 and the circuit board 20.

[0055] Refer to Figure 12As shown, the conductive clamping structure 24 has a conductive base portion 241, a first conductive clamping portion 242, and a second conductive clamping portion 243. The conductive base portion 241 is fixed inside the second socket 23. Both the first conductive clamping portion 242 and the second conductive clamping portion 243 are connected to the conductive base portion 241. The first conductive clamping portion 242 and the second conductive clamping portion 243 are used to generate a clamping force that approaches each other when the hard steel needle 314 is inserted into the second socket 23, so as to clamp the other end of the hard steel needle 314 inserted into the second socket 23 between the first conductive clamping portion 242 and the second conductive clamping portion 243.

[0056] In an embodiment of the present application, the conductive base portion 241 is provided with an elastic limiting portion 244, and a limiting groove 231 is further provided inside the second socket 23. The elastic limiting portion 244 can be snapped into the limiting groove 231, thereby fixing the conductive base portion 241 inside the second socket 23.

[0057] In the present application, as Figure 9 shown, an installation post 111 can also be provided in the accommodating cavity 11. An internal threaded hole 112 is provided in the installation post 111. A bolt hole 25 is provided on the circuit board 20. Then, by means of a bolt passing through the bolt hole 25 and being screwed into the internal threaded hole 112, the circuit board 20 can be secondarily fixed. Embodiment

[0058] As Figure 1 shown, this embodiment provides a motor 200, which includes the encoder assembly 100 in the first embodiment, and further includes an encoder cover 10, an encoder rotor 40, and a motor body 50. The encoder cover 10 is fixed to the motor body 50. When the circuit board 20 is fixed to one side of the connector 32, it is located inside the accommodating cavity.

[0059] In a specific embodiment, the motor body 50 is composed of a stator (not shown in the figure) and a rotor 51. The rotating shaft 52 of the rotor 51 is connected to the center of the encoder rotor 40 inside the accommodating cavity 11 of the encoder cover 10, so that the encoder rotor 40 can rotate synchronously with the rotor 51 through the rotating shaft 52. A photodetector 21 is provided on the circuit board 20. A plurality of grating holes (not shown in the figure) are provided on the encoder rotor 40 and surround the center of the encoder rotor 40. The plurality of grating holes are arranged along the radial direction of the encoder rotor 40. During the rotation of the encoder rotor 40 with the rotor 51 through the rotating shaft 52, the photodetector 21 can detect the light passing through the grating holes. Thus, the photodetector 21 can output corresponding pulse signals under the action of the processor, and the rotational speed and other position information of the current motor can be reflected by calculating the number of pulses output per unit time (for example, second, s).

[0060] The encoder cover 10 is further provided with a flange 12, and the flange 12 is connected to the motor body 50 of the motor 200. In a preferred embodiment, the flange 12 is provided with a first bolt hole 121, and a first threaded hole is provided at a preset position of the motor body 50. The encoder cover 10 is fixed to the motor body 50 by passing a first bolt through the first bolt hole 121 and screwing it into the first threaded hole.

[0061] In summary, in the encoder assembly and the motor provided by the present application, since the connector is fixedly arranged on the encoder cover, one end of the conductive fixing component is electrically connected to the connector, and the other end of the conductive fixing component is electrically connected to the circuit board, and the circuit board can be fixed on one side of the connector. Since the conductive fixing component can be fixed inside the accommodating cavity of the encoder cover, and the circuit board is connected to the other end of the conductive fixing component, the circuit board can be fixed inside the accommodating cavity of the encoder cover. In this way, the conductive fixing component has the function of electrically connecting the circuit board and the connector, and at the same time can also fix the circuit board. Compared with the related art, there is no need to provide a bracket, which can reduce the cost and reduce the space of the accommodating cavity of the encoder cover, thereby reducing the overall volume of the present encoder assembly.

[0062] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention.
