[0036] Referring to Figures 1 to 4, this utility model proposes a motor 100, which includes a housing 1, an end cover assembly, a drive component 6, and a gearbox 7. The housing 1 has a mounting cavity 13 and a first opening 11 communicating with the mounting cavity 13. The first opening 11 is located at one end of the mounting cavity 13. The end cover assembly includes a front cover 2, which is detachably fitted onto the first opening 11 and a second opening 12. The drive component 6 is disposed in the mounting cavity 13. The gearbox 7 is disposed between the drive component 6 and the front cover 2, and the gearbox 7 is detachably connected to the front cover 2. The output end of the drive component 6 is connected to the gearbox 7. The gearbox 7 has an output shaft, which at least partially penetrates the front cover 2 and extends out of the mounting cavity 13.

[0037] In this embodiment, the housing 1 serves as the supporting frame for the entire motor 100, and its interior has a mounting cavity 13 for accommodating core components such as the drive unit 6 and the gearbox 7. One end of the mounting cavity 13 has a first opening 11, and the front cover 2 is detachably fitted onto the first opening 11, thereby securely encapsulating the drive unit 6 and the gearbox 7 inside the housing 1. The drive unit 6 is located within the mounting cavity 13, and its output end is connected to the gearbox 7, converting electrical energy into mechanical energy. Through the transmission action of the gearbox 7, the power is transmitted to the output shaft, which is used to connect to an external load device to drive the load device. The front cover 2 and the housing 1 are detachably connected, and the gearbox 7 is also detachably connected to the front cover 2. This allows the front cover 2 to be removed from the housing 1 and a different level of gearbox 7 to be replaced when the gearbox 7 needs to be replaced to adapt to different workloads or speed requirements. Furthermore, different lengths of the housing 1 can be used to adapt the length of the housing 1 to the size of the gearbox 7, thereby improving the adaptability of the motor 100.

[0038] In actual implementation, a cross coupling can be installed on the portion of the output shaft extending out of the mounting cavity 13, and the cross coupling is connected to the output shaft via a pin. Optionally, the drive component 6 is a motor. Optionally, the drive component 6 is detachably disposed in the mounting cavity 13, so that the motor 100 can be replaced with any drive component 6.

[0039] In an embodiment of this utility model, as shown in Figures 1 and 2, the front cover 2 is provided with a first peripheral sidewall 21, which at least partially extends into the mounting cavity 13 and abuts against the housing 1.

[0040] In this embodiment, the first peripheral sidewall 21 extends into the mounting cavity 13 of the housing 1 and abuts tightly against the inner wall of the housing 1, further enhancing the sealing effect and strengthening the connection between the housing 1 and the front cover 2.

[0041] In an embodiment of this utility model, as shown in Figures 1 and 2, the first peripheral sidewall 21 is provided with a first step 211, which abuts against the end face of the first opening 11.

[0042] In this embodiment, a first step 211 is provided on the first peripheral sidewall 21. The first step 211 abuts tightly against the end face of the first opening 11 of the housing 1 to facilitate the positioning and installation of the front cover 2. The first step 211 is arranged in a ring shape and abuts tightly against the end face of the first opening 11.

[0043] Optionally, the first peripheral sidewall 21 is provided with a first protrusion 212, and the housing 1 is provided with a first groove 111, with the first protrusion 212 confined within the first groove 111. In this embodiment, the cooperation between the first protrusion 212 and the first groove 111 not only serves a positioning function but also effectively prevents the relative rotation of the front cover 2 during the operation of the motor 100, ensuring the reliability of the connection between the front cover 2 and the housing 1. Multiple sets of the first protrusion 212 and the first groove 111 can be provided, with multiple sets of the first protrusion 212 and the first groove 111 spaced apart circumferentially along the first peripheral sidewall 21 and the housing.

[0044] Optionally, the first peripheral sidewall 21 is provided with a first connecting hole 213, the housing 1 is provided with a second connecting hole 14, and the end cap assembly includes a first connector 4, which passes through the first connecting hole 213 and the second connecting hole 14. In this embodiment, the first connecting hole 213 and the second connecting hole 14 are correspondingly arranged, and the front end cap 2 is firmly fixed to the housing 1 by the first connector 4 (such as bolts, screws, etc.). This connection method not only provides sufficient mechanical strength but also facilitates disassembly and maintenance operations when needed. The first connector 4 is arranged radially towards the motor 100.

[0045] Optionally, a first sealing ring 22 is also provided on the outer periphery of the first peripheral sidewall 21, and the first sealing ring 22 abuts against the housing 1. In this embodiment, the first sealing ring 22 abuts tightly against the inner wall of the housing 1, forming an effective sealing barrier to prevent the intrusion of external impurities. Optionally, the first peripheral sidewall 21 is provided with a first limiting groove, and the first sealing ring 22 is limited in the first limiting groove.

[0046] In an embodiment of this utility model, as shown in Figures 1 to 3, the front cover 2 is further provided with a through hole 23 for the output shaft to extend through, the output shaft passes through the through hole 23, and the end cover assembly also includes an oil seal 24, which is sleeved on the output shaft and abuts against the hole wall of the through hole 23.

[0047] In this embodiment, a through hole 23 is provided in the central region of the front end cover 2 for the output shaft of the gearbox 7 to pass through. To ensure the sealing of the output shaft during rotation, the end cover assembly also includes an oil seal 24, which is sleeved on the output shaft and tightly abuts against the wall of the through hole 23 in the front end cover 2, thereby effectively preventing the leakage of lubricating oil and the entry of external impurities.

[0048] Optionally, the gearbox 7 has a positioning protrusion at the end facing the front cover 2, and the cross-section of the through hole 23 at the end facing the gearbox 7 is the same as the cross-section of the positioning protrusion, but not circular. The positioning protrusion extends into the through hole 23 to prevent the front cover 2 and the gearbox 7 from rotating relative to each other.

[0049] In the embodiments of this utility model, as shown in Figures 1 to 3, the front end cover 2 is provided with a third connecting hole 25, the gearbox 7 is provided with a fourth connecting hole 71, and the end cover assembly also includes a second connecting member 5, which passes through the third connecting hole 25 and the fourth connecting hole 71.

[0050] In this embodiment, the front cover 2 has a third connecting hole 25, while the gearbox 7 has a corresponding fourth connecting hole 71. The gearbox 7 is securely mounted on the front cover 2 by passing a second connecting piece 5 (such as a bolt or screw) through the third connecting hole 25 and the fourth connecting hole 71. This detachable connection method allows the gearbox 7 to be easily removed from the front cover 2 for replacement simply by removing the second connecting piece 5, without requiring extensive disassembly of the entire motor 100, thus greatly improving replacement efficiency.

[0051] In actual implementation, the second connecting member 5 is set along the axial direction of the motor 100.

[0052] In an embodiment of this utility model, as shown in Figures 1 to 3, the front cover 2 is also provided with a receiving groove 26, and the third connecting hole 25 connects to the bottom of the receiving groove 26, and the receiving groove 26 is filled with sealant.

[0053] In this embodiment, when installing the front cover 2, the groove 26 is filled with sealant. This sealant can fill the tiny gap between the second connector 5 and the front cover 2, forming a reliable sealing barrier. This not only enhances the sealing performance at the connection between the second connector 5 and the front cover 2, but also provides a certain buffering effect on the minor vibrations of the gearbox 7 during operation, extending the service life of the gearbox 7.

[0054] In the embodiments of this utility model, as shown in Figures 1 and 2, the end of the housing 1 opposite to the first opening 11 is provided with a second opening 12. The end cover assembly also includes a rear end cover 3. The rear end cover 3 is detachably covered on the second opening 12. The rear end cover 3 is provided with a second peripheral sidewall 31. The second peripheral sidewall 31 extends at least partially into the mounting cavity 13 and abuts against the housing 1.

[0055] In this embodiment, the design of the rear end cover 3 is similar to that of the front end cover 2. The rear end cover 3 and the front end cover 2 complement each other and together complete the sealing of the mounting cavity 13. The second peripheral sidewall 31 of the rear end cover 3 extends at least partially into the mounting cavity 13 of the housing 1 and abuts tightly against the inner wall of the housing 1, further enhancing the sealing effect and strengthening the connection between the housing 1 and the rear end cover 3.

[0056] In the embodiments of this utility model, as shown in Figures 1 to 4, the motor 100 further includes a magnetic angle sensor 8, which is located on the side of the rear end cover 3 facing the mounting cavity 13. The drive member 6 is provided with a detection shaft 61 that rotates synchronously with the output end. The detection shaft 61 is provided with a magnetic element 62, and the magnetic angle sensor 8 is used to detect the movement of the magnetic element 62.

[0057] In this embodiment, the detection shaft 61 rotates synchronously with the drive component 6, and the magnetic component 62 on the detection shaft 61 also rotates with the detection shaft 61. The magnetic angle sensor 8 can detect the rotation of the output shaft of the drive component 6 by detecting the change in the magnetic field of the magnetic component 62 as it rotates with the detection shaft 61. Specifically, by detecting the movement of the magnetic component 62, the magnetic angle sensor 8 can accurately measure parameters such as the rotation angle and speed of the output shaft of the drive component 6, and convert these parameters into electrical signals, which are then fed back to the control system of the motor 100 in real time. Based on the received signals, the control system precisely controls the operating state of the motor 100, such as adjusting the speed and torque output of the motor 100, to meet the process requirements under different working scenarios.

[0058] Understandably, when motor 100 is a brushless DC motor 100, the magnetic angle sensor 8 can replace the three Hall elements used for three-phase six-state operation, achieving electronic commutation. This significantly saves material and manufacturing costs, greatly enhancing the commercial value of motor 100. In practical implementation, the magnetic angle sensor 8 is a differential Hall sensor. The magnetic component 62 is a sensing bead with a pair of magnetic poles. The sensor chip senses the magnetic changes of the magnetic component 62 during rotation, outputting different pulse signals, which are transmitted to an external control board for data acquisition to detect the rotational position angle of motor 100 from 0° to 360°, while simultaneously generating signals in three different directions: X, Y, and Z.

[0059] Optionally, the detection axis 61 is coaxially arranged with the output end of the drive unit 6.

[0060] Optionally, a magnetic seat is fitted onto the detection shaft 61, the magnetic seat has a fixing groove, and the magnetic component 62 is fixed in the fixing groove.

[0061] Optionally, the magnetic angle sensor 8 is mounted on the circuit board, the rear cover 3 has a latch, and the circuit board has a locking hole. The latch is confined within the locking hole to allow for detachable installation of the circuit board and the rear cover 3. The circuit board and the rear cover 3 can also be connected by screws or bolts.

[0062] Optionally, the rear end cover 3 is provided with a through hole communicating with the mounting space to allow the connecting wires of the circuit board and the drive unit 6 to extend. The rear end cover 3 is also provided with a reserved connection hole for mounting the power supply 100. Sealant can be filled between the connection hole and the connecting wire to effectively improve the sealing.

[0063] In embodiments of this invention, the magnetic component 62 and the magnetic angle sensor 8 are eccentrically positioned.

[0064] In this embodiment, the eccentric arrangement of the magnetic component 62 and the magnetic angle sensor 8 enables the magnetic angle sensor 8 to more sensitively detect changes in the magnetic properties of the magnetic component 62, generating unique signal characteristics and thus improving the resolution and accuracy of the detection signal. This not only optimizes the control effect of the motor 100 but also allows the motor 100 to maintain high-precision control performance even when running at low speeds, further expanding the application range of the motor 100.

[0065] In an embodiment of this utility model, as shown in Figures 1 to 3, the second peripheral sidewall 31 is provided with a second step 311, which abuts against the end face of the second opening 12. In this embodiment, the second peripheral sidewall 31 is provided with a second step 311, which abuts tightly against the end face of the second opening 12 of the housing 1 to facilitate the positioning and installation of the rear end cover 3. The second step 311 is annularly arranged and abuts tightly against the end face of the second opening 12.

[0066] Optionally, the second peripheral sidewall 31 is provided with a second protrusion 312, and the housing 1 is provided with a second groove 121, with the second protrusion 312 confined within the second groove 121. In this embodiment, the cooperation between the second protrusion 312 and the second groove 121 not only serves a positioning function but also effectively prevents the relative rotation of the rear end cover 3 during the operation of the motor 100, ensuring the reliability of the connection between the rear end cover 3 and the housing 1. Multiple sets of the second protrusion 312 and the second groove 121 can be provided, with multiple sets of the second protrusion 312 and the second groove 121 spaced apart circumferentially along the second peripheral sidewall 31 and the housing.

[0067] Optionally, the second peripheral sidewall 31 is provided with a fifth connecting hole 313, the housing 1 is provided with a sixth connecting hole 15, and the end cap assembly includes a third connecting member 9, which passes through the fifth connecting hole 313 and the sixth connecting hole 15. In this embodiment, the fifth connecting hole 313 and the sixth connecting hole 15 are correspondingly arranged, and the rear end cap 3 is firmly fixed to the housing 1 by the third connecting member 9 (such as a bolt, screw, etc.). This connection method not only provides sufficient mechanical strength, but also facilitates disassembly and maintenance operations when needed. The direction of the third connecting member 9 is radial to the motor 100.

[0068] Optionally, a second sealing ring 32 is also provided on the outer periphery of the second peripheral sidewall 31, and the second sealing ring 32 abuts against the housing 1. In this embodiment, the second sealing ring 32 abuts tightly against the inner wall of the housing 1, forming an effective sealing barrier, effectively preventing external impurities from entering the motor 100 from the connection between the rear end cover 3 and the housing 1, protecting the internal components of the motor 100 from contamination and damage, and extending the service life of the motor 100. Optionally, the second peripheral sidewall 31 is provided with a second limiting groove, and the second sealing ring 32 is limited in the second limiting groove.
