Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a motor. Background Art

[0002] In the related art, the servo motor used in the robot is provided with a power interface and an encoder feedback interface respectively, and a pair of opposing aviation plugs are used to transmit the power signal and the encoder feedback signal respectively.

[0003] However, the dual aviation plugs invisibly increase a lot of manufacturing costs, and the overall size of the dual connectors after matching is not conducive to the current increasingly smaller application scenario requirements.

[0004] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the utility model provides a motor.

[0007] In view of this, in the motor provided by the utility model, the motor includes: a shell; an electrical component, which is arranged in the shell; a line connector, which is connected to the shell, and the line connector includes a first mounting position and a second mounting position; a power supply line, which is arranged at the first mounting position, the power supply line is connected to the electrical component, and the power supply line is used to supply power to the electrical component; a signal line, which is arranged at the second mounting position, the signal line is connected to the electrical component, and the signal line is used to transmit feedback electrical signals.

[0008] In this technical solution, the motor includes a casing, which is used to shield and protect the working structure inside the motor, and the casing forms the outer surface of the motor.

[0009] The motor also includes a power supply circuit and a signal circuit. The first end of the power supply circuit is connected to the power supply outside the shell, and the second end of the power supply circuit penetrates into the inside of the shell and is connected to the electrical components inside the shell. The power supply circuit is used to transmit electrical energy to the electrical components inside the shell to drive the electrical components and the power components to work and realize the conversion of electrical energy and mechanical energy. The first end of the signal circuit is connected to the electrical components inside the shell, and the second end of the signal circuit extends to the outside of the shell. The signal circuit is used to transmit feedback electrical signals to the outside of the shell. The feedback electrical signals can reflect the working status of the motor, which is convenient for users to control the working conditions of the motor in real time. The control circuit can also control the operation of the motor through feedback electrical signals to ensure that the working status of the motor meets user needs. In order to ensure the stability and reliability of the electrical connection, the power supply circuit and the signal circuit need to be fixed to the shell.

[0010] On this basis, the motor also includes a line connector, which is fixed on the housing, and the line connector includes a first mounting position and a second mounting position, the power supply line is arranged on the first mounting position, and the first mounting position can provide positioning for the power supply line, and the signal line is arranged on the second mounting position, and the second mounting position can provide positioning for the signal line. During the assembly process, the power supply line is first initially positioned on the line connector through the first mounting position, and the signal line is initially positioned on the line connector through the second mounting position, and then the line connector is connected to the housing to synchronously complete the installation of the power supply line on the housing and the installation of the signal line on the housing.

[0011] It can be seen that the present application sets the first installation position and the second installation position on the line connector at the same time, so that a single line connector can simultaneously meet the positioning and installation requirements of the power supply line and the signal line. Compared with the dual-interface solution in the related art, eliminating a line connection structure is conducive to reducing the manufacturing cost of the motor, and compared with the dual-interface solution, the space occupied by a single line connector is smaller, which can reduce the overall size of the motor, which is conducive to achieving the miniaturization and lightweight requirements of the motor. This solves the technical defects of high manufacturing cost and large overall size of dual aviation plugs in the related art, and further achieves the technical effect of optimizing the motor structure, improving the compactness of the motor structure, reducing the motor production cost, and improving the market competitiveness of the motor.

[0012] Specifically, the line connector not only meets the positioning requirements of the power supply line and the signal line, but also meets the sealing requirements between the power supply line and the housing, and between the signal line and the housing, to prevent liquid and dust from entering the interior of the housing. At the same time, the line connector can also meet the signal shielding requirements of the power supply line and the signal line, to ensure that the power supply signal in the power supply line and the feedback electrical signal in the signal line are not interfered with. In this regard, the technical solution does not limit the specific structure of the line connector, and it is sufficient to meet the above-mentioned positioning, sealing and shielding requirements.

When the opening is not covered, the user can complete the connection between the power supply line and the electrical component, and the connection between the signal line and the electrical component at the opening.

After the cover is assembled, the cover covers the opening to provide protection for the electrical component, the power supply line and the signal line.

[0016] Specifically, the cover body can be fixed on the housing by a plurality of screws.

[0017] Through holes are arranged on the peripheral side of the electrical component, and the power supply line and the signal line need to pass through the through holes to enter the shell. Arranging the through holes around the electrical component can, on the one hand, provide convenient conditions for the wiring of the power supply line and the signal line on the inside of the shell, and on the other hand, it can cooperate with the opening to reduce the difficulty of electrical connection of the power supply line and the signal line.

[0018] Specifically, during the assembly process, the power supply line and the signal line are first installed on the line connector, and the line connector is fixed on the housing, wherein the power supply line and the signal line need to reserve a certain length inside the housing to facilitate the connection of the electrical components. Afterwards, the user performs the connection operation between the power supply line and the electrical components, and the connection operation between the signal line and the electrical components at the opening. Finally, after completing the electrical connection operation of the power supply line and the signal line, the cover body is closed on the opening to complete the assembly process.

[0019] It can be seen that by providing openings and through holes, the technical effect of reducing the complexity of motor assembly and improving the compactness of the motor structure can be achieved.

[0022] The mounting plate is attached to the outer side of the housing, and the shape of the mounting plate can be adjusted to improve the fit between the mounting plate and the housing, thereby improving the sealing effect at the through hole and preventing liquid or dust from entering the through hole through the gap between the housing and the mounting plate. At the same time, by opening mounting holes of different shapes and sizes on the mounting plate, the mounting plate can be adapted to line connectors of different models, so that the motor can be adapted to line connectors of different models by replacing the mounting plate without changing the shape and size of the through hole.

[0023] Specifically, the connecting component is a screw, and a screw hole is provided on the housing. The screw passes through the mounting plate and is screwed into the screw hole to fix the mounting plate to the outside of the housing. There are multiple screws, and the positioning stability of the mounting plate and the sealing reliability between the mounting plate and the housing can be improved by providing multiple screws.

[0024] In some technical solutions of the present utility model, optionally, the motor further includes: a first sealing component, which is arranged between the mounting plate and the housing; and a second sealing component, which is arranged between the hole wall of the mounting hole and the line connector.

[0025] In this technical solution, the motor also includes a first sealing component, which is arranged between the mounting plate and the shell.

[0027] The motor also includes a second sealing component, which is arranged between the hole wall of the through hole and the line connector. After the line connector is plugged in and installed, the second sealing component is pressed between the outer surface of the line connector and the hole wall of the through hole, so as to seal the gap between the through hole and the line connector by the second sealing component that is deformed under pressure, thereby preventing liquid and dust from entering the housing through the gap between the line connector and the through hole, and cooperating with the first sealing component to achieve double sealing, thereby improving the sealing reliability of the motor, improving the safety of the motor, and reducing the failure rate of the motor.

[0028] Specifically, the second sealing component is a sealing ring, and the sealing ring is sleeved on the peripheral side of the line joint.

[0029] In some technical solutions of the utility model, optionally, the motor also includes: a power assembly, which is arranged in the shell, and the power assembly includes a transmission shaft, which passes through the shell from the side of the shell facing away from the opening, and the electrical assembly is located between the opening and the power assembly.

[0030] In this technical solution, the motor also includes a power component, which is arranged in the shell, and the power component is located on the side of the electrical component facing away from the opening. By arranging the electrical component between the opening and the power component, on the one hand, interference between the transmission shaft and the power supply line and the signal line can be avoided, and on the other hand, the power component can be avoided from blocking the electrical component on the inside of the opening, thereby providing convenient conditions for users to connect the power supply line and the electrical component, as well as to connect the signal line and the electrical component.

[0032] Specifically, the power assembly includes a stator, a rotor and a transmission shaft. The end of the transmission shaft passes through the side of the shell facing away from the opening to the outside of the shell. A keyway is provided on the peripheral side of the transmission shaft, and the transmission shaft outputs mechanical energy outward through the keyway.

The first connector is provided with a power input terminal, and the power supply line is connected to the power input terminal. The power supply line supplies power to the power component and the brake respectively through the first connector. The brake user performs emergency braking on the power component to improve the safety and reliability of the motor.

[0038] On this basis, the first connector and the second connector are respectively located on opposite sides of the encoding disk, so that the encoding disk is located between the first connector and the second connector. By arranging the first connector and the second connector on opposite sides of the encoding disk, the wiring of the power supply line and the signal line can be optimized, so that the signal line and the power supply line are separated to the two sides of the encoding disk after entering the shell, thereby avoiding the power supply line and the signal line from being entangled with each other inside the shell on the one hand, and reducing the signal interference between the power supply line and the signal line on the other hand. This achieves the technical effect of optimizing the motor structure layout, improving the motor working reliability, and reducing the motor failure rate.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0069] Refer to the following Figures 1 to 3 A motor according to some embodiments of the present invention is described.

[0070] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a motor 100, which includes: a housing 110; an electrical component 120, which is arranged in the housing 110; a line connector 130, which is connected to the housing 110, and the line connector 130 includes a first mounting position 1302 and a second mounting position 1304; a power supply line 140, which is arranged at the first mounting position 1302, the power supply line 140 is connected to the electrical component 120, and the power supply line 140 is used to supply power to the electrical component 120; a signal line 150, which is arranged at the second mounting position 1304, the signal line 150 is connected to the electrical component 120, and the signal line 150 is used to transmit feedback electrical signals.

[0071] In this embodiment, the motor 100 includes a housing 110 . The housing 110 is used to shield and protect the working structure inside the motor 100 . The housing 110 forms the outer surface of the motor 100 .

[0072] The motor 100 also includes a power supply line 140 and a signal line 150. The first end of the power supply line 140 is connected to the power supply outside the housing 110. The second end of the power supply line 140 penetrates into the inner side of the housing 110 and is connected to the electrical component 120 in the housing 110. The power supply line 140 is used to transmit electric energy to the electrical component 120 in the housing 110 to drive the electrical component 120 and the power component 170 to work and realize the conversion of electric energy and mechanical energy. The first end of the signal line 150 is connected to the electrical component 120 inside the housing 110. The second end of the signal line 150 extends to the outer side of the housing 110. The signal line 150 is used to transmit feedback electrical signals to the outer side of the housing 110. The feedback electrical signals can reflect the working state of the motor 100, which is convenient for users to control the working condition of the motor 100 in real time. The control circuit can also control the motor 100 through feedback electrical signals to ensure that the working state of the motor 100 meets the user's needs. In order to ensure the stability and reliability of the electrical connection, the power supply line 140 and the signal line 150 need to be fixed to the housing 110.

[0073] On this basis, the motor 100 further includes a line connector 130, which is fixed on the housing 110. The line connector 130 includes a first mounting position 1302 and a second mounting position 1304. The power supply line 140 is arranged on the first mounting position 1302, and the first mounting position 1302 can provide positioning for the power supply line 140. The signal line 150 is arranged on the second mounting position 1304, and the second mounting position 1304 can provide positioning for the signal line 150. During the assembly process, the power supply line 140 is first initially positioned on the line connector 130 through the first mounting position 1302, and the signal line 150 is initially positioned on the line connector 130 through the second mounting position 1304, and then the line connector 130 is connected to the housing 110 to synchronously complete the installation of the power supply line 140 on the housing 110 and the installation of the signal line 150 on the housing 110.

[0074] It can be seen that, by setting the first installation position 1302 and the second installation position 1304 on the line connector 130 at the same time, the present application enables a single line connector 130 to simultaneously meet the positioning and installation requirements of the power supply line 140 and the signal line 150. Compared with the dual interface solution in the related art, the omission of a line connection structure is conducive to reducing the manufacturing cost of the motor 100, and compared with the dual interface solution, the space occupied by the single line connector 130 is smaller, which can reduce the overall size of the motor 100, which is conducive to achieving the miniaturization and lightweight requirements of the motor 100. Thus, the technical defects of high manufacturing cost and large overall size of the dual aviation plug existing in the related art are solved, and the technical effects of optimizing the structure of the motor 100, improving the compactness of the motor 100 structure, reducing the production cost of the motor 100, and improving the market competitiveness of the motor 100 are achieved.

[0075] Specifically, the line connector 130 not only meets the positioning requirements of the power supply line 140 and the signal line 150, but also meets the sealing requirements between the power supply line 140 and the housing 110, and the sealing requirements between the signal line 150 and the housing 110, so as to prevent liquid and dust from entering the interior of the housing 110. At the same time, the line connector 130 can also meet the signal shielding requirements of the power supply line 140 and the signal line 150, so as to ensure that the power supply signal in the power supply line 140 and the feedback electrical signal in the signal line 150 are not interfered. In this regard, this embodiment does not limit the specific structure of the line connector 130, and it is sufficient to meet the above positioning, sealing and shielding requirements.
