Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a motor lead-out structure and a motor. Background Technology

[0002] With the rapid development of various automated equipment, the requirements for motors, which serve as the power source for these devices, in terms of performance, electrical parameters, and structure are also increasing. Currently, most motors on the market have power outlet boxes that are independent of the motor housing. These boxes are relatively large and fixed in position, which may not meet the needs of some devices with specific installation requirements, such as robots with limited installation space and compact structural layouts.

[0003] Therefore, the inventors propose a motor cable outlet structure and a motor. The cable outlet structure is designed to reduce the size while achieving adjustability of the cable outlet position, which can fully adapt to the installation requirements of various devices with limited space and possible changes in installation position. Summary of the Invention

[0004] To address the problem that existing motors have fixed and unchangeable power output structures, making them unsuitable for devices with limited installation space or potentially changing installation locations, this invention proposes a motor output structure and a motor.

[0005] In a first aspect, the present invention provides a motor lead-out structure, comprising:

[0006] A conductive plate, wherein the conductive plate is disposed in an assembly groove constructed on the outer surface of the motor housing, and the conductive plate is electrically connected to a lead-out terminal of the motor formed at the assembly groove; and

[0007] The cable outlet connector is detachably mounted on the surface of the conductive plate to adjust its position on the conductive plate surface. The conductive part of the cable outlet connector is in contact with and electrically connected to the surface of the conductive plate.

[0008] In one embodiment, the outgoing connector is magnetically connected to the surface of the conductive plate, and the conductive plate is made of magnetic material or has multiple magnetically attached parts made of magnetic material embedded on its surface.

[0009] In one embodiment, the system further includes a sealing cover disposed on the assembly groove. The sealing cover is used to close the assembly groove. The sealing cover has multiple connection ports that correspond to different positions on the surface of the conductive plate. The outgoing connector is connected to the surface of the conductive plate through the connection ports.

[0010] In one embodiment, the sealing cap includes a plurality of sub-caps that can be placed over the connection port to seal the corresponding connection port that does not mate with the outgoing connector.

[0011] In one embodiment, the plurality of the connection ports are arranged in an array on the sealing cover.

[0012] In one embodiment, the outgoing terminal is located inside the assembly slot and at one end of the assembly slot, and the outgoing terminal is electrically connected to the side or bottom surface of the conductive plate via a connecting wire.

[0013] In one embodiment, the bottom of the assembly groove is provided with a terminal groove at the location of the outgoing terminal, and the outgoing terminal is disposed in the terminal groove and is completely located within the terminal groove.

[0014] In one embodiment, the conductive plate has a filling hole for injecting filler into the assembly groove. The filler is used to seal the gap between the conductive plate and the assembly groove and to connect the conductive plate and the assembly groove as a whole.

[0015] In one embodiment, a positioning platform is provided around the perimeter of the assembly slot, the positioning platform being used to support and position the perimeter edges of the conductive plate.

[0016] In one embodiment, the peripheral edges of the conductive plate are covered with an insulating layer that isolates the conductive plate from contact with the mounting groove and the sealing cap.

[0017] In one embodiment, the sealing cover is provided with a heat dissipation mechanism, which includes one or more of the following: heat dissipation ribs formed on the outer surface of the sealing cover, an air-cooling component disposed on the sealing cover, and a liquid-cooling component disposed on the sealing cover.

[0018] Secondly, the present invention proposes a motor that includes the aforementioned motor lead-out structure, thereby possessing all of its technical effects.

[0019] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0020] The present invention provides a motor lead-out structure and a motor, which, compared with the prior art, at least have the following characteristics.

[0021] Beneficial effects:

[0022] The present invention discloses a motor cable outlet structure and a motor, which utilizes a conductive plate to provide a mounting surface for the cable outlet connector.

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] Example 1

[0034] An embodiment of the present invention provides a motor lead-out structure, comprising:

[0035] Conductive plate 1 is disposed in an assembly groove 41 constructed on the outer surface of motor housing 4, and conductive plate 1 is electrically connected to the output terminal 5 of the motor formed at the assembly groove 41; and

[0036] The cable outlet connector 2 is detachably mounted on the surface of the conductive plate 1 so that its position on the surface of the conductive plate 1 can be adjusted. The conductive part of the cable outlet connector 2 is in contact with and electrically connected to the surface of the conductive plate 1.

[0037] Specifically, the conventional motor's cable exit structure is located at the top of the motor, meaning a connector is fixed to the top of the motor housing 4 using bolts or welding. This method often results in a relatively large size because it requires sufficient assembly space for the bolts or welds. Furthermore, this connection method is limited by the position of the internal cable exit terminal 5 of the motor; the position of the connector that needs to connect to terminal 5 cannot be adjusted. Therefore, the application of motors with conventional cable exit structures is restricted in some scenarios. For example, servo motors are widely used in various compact robotic devices, but the current size and relative position of the servo motor's cable exit structure may not meet the assembly requirements of some robots with limited assembly space.

[0038] To address the above problems, this embodiment proposes a motor cable output structure, as shown in the attached drawings. Figures 1 to 5 First, a mounting slot 41 is made on the top of the motor housing 4, as shown in the attached diagram. Figure 3 As shown, the size of the area covered by the assembly slot 41 is preferably matched with the area of ​​the top region of the motor housing 4, and the original position of the motor's output terminal 5 also corresponds to the position within the assembly slot 41. Then, a conductive plate 1 matching the size of the assembly slot 41 is installed in the assembly slot 41, and the terminals 12 on the conductive plate 1 are electrically connected to the output terminal 5 via cables. Finally, an output connector 2 is installed on the surface of the conductive plate 1, and the output connector 2 is detachably connected to the surface of the conductive plate 1; in the connected state, the conductive part of the output connector 2 contacts the surface of the conductive plate 1 and achieves electrical connection.

[0039] The cable outlet structure of the present invention utilizes a conductive plate 1 to provide a mounting surface for the cable outlet connector 2. In this way, the cable outlet connector 2 can adjust its relative position on the conductive plate 1 surface at any time according to the assembly space conditions of the corresponding equipment through a detachable connection method, thereby meeting the assembly requirements of the corresponding equipment.

[0040] Preferably, the cable outlet connector 2 is magnetically connected to the surface of the conductive plate 1, and the conductive plate 1 is made of magnetic material or has multiple magnetically attached parts 11 made of magnetic material embedded on its surface.

[0041] Specifically, there are various ways to detachably connect the cable outlet connector 2 to the surface of the conductive plate 1. For example, snap-fit ​​structures can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through the snap-fit ​​structures; alternatively, screw holes can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through bolts. In this embodiment, a magnetic connection is preferably used between the cable outlet connector 2 and the surface of the conductive plate 1, which allows for convenient adjustment of the connection position; furthermore, the magnetic connection eliminates the need for additional connecting components, significantly reducing the volume of the cable outlet connector 2 and the entire cable outlet structure.

[0042] For magnetic connections, the entire conductive plate 1 can be supported by a conductive magnetic material, and the part of the wire connector 2 that contacts the conductive plate 1 can also be made of magnetic material. This allows the wire connector 2 to be positioned arbitrarily on the surface of the conductive plate 1. Alternatively, considering the influence of magnetic materials on conductivity, multiple magnetic suction parts 11 made of magnetic material can be embedded in various locations on the non-magnetic conductive plate 1 (e.g., multiple magnetic blocks distributed in a copper plate). The part of the wire connector 2 that contacts the conductive plate 1 can also be made of magnetic material. This allows the wire connector 2 to be positioned between multiple predetermined areas (the areas where the magnetic suction parts 11 are distributed) on the surface of the conductive plate 1. (See attached figure.) Figure 1 As shown, four magnetic suction parts 11 are provided in an area corresponding to the outgoing connector 2.

[0043] Furthermore, the output terminal 5 is located inside the assembly groove 41 and at one end of the assembly groove 41, and the output terminal 5 is electrically connected to the side or bottom surface of the conductive plate 1 through a connecting wire.

[0044] Specifically, as shown in the attached diagram. Figure 2 and Figure 3 As shown, the output terminal 5 is located at one end inside the assembly slot 41. When the output terminal 5 is connected to the conductive plate 1, it can be connected to the side of the conductive plate 1 or to the bottom surface of the conductive plate 1 (the conductive plate 1 covers the output terminal 5). In this embodiment, it is preferred to connect the output terminal 5 to the bottom surface of the conductive plate 1. Corresponding terminals 12 are provided on the bottom surface of the conductive plate 1, as shown in the attached figure. Figure 4 As shown; compared to connecting to the side and the output terminal 5, the bottom connection method allows the conductive plate 1 to have a larger area, thus providing more options for the output connector 2.

[0045] Furthermore, the bottom of the assembly groove 41 is constructed with a terminal groove 411 at the location of the outgoing terminal 5, and the outgoing terminal 5 is disposed in the terminal groove 411 and is completely located within the terminal groove 411.

[0046] Specifically, as shown in the attached diagram. Figure 3As shown, the outgoing terminal 5 is disposed within the terminal slot 411, thus the outgoing terminal 5 does not actually occupy the space of the assembly slot 41, thereby leaving space for the connecting cable between the outgoing terminal 5 and the conductive plate 1. Furthermore, the size of the conductive plate 1 can be designed to match the assembly slot 41, increasing the area of ​​the conductive plate 1, and thus allowing the bottom surface of the conductive plate 1 to be connected to the outgoing terminal 5.

[0047] Furthermore, the conductive plate 1 is provided with a filling hole for injecting filler into the assembly groove 41. The filler is used to seal the gap between the conductive plate 1 and the assembly groove 41 and to connect the conductive plate 1 and the assembly groove 41 into one piece.

[0048] Specifically, after the conductive plate 1 is installed into the assembly groove 41, there is only a relative positional constraint between the two, but they are not completely fixed, and there are some gaps between them. Therefore, further fixing and electrical sealing are required. In this embodiment, filler (such as epoxy resin) is injected into the assembly groove 41 through the filling hole on the conductive plate 1. After the filler enters the assembly groove 41, it will further fill the gaps between the conductive plate 1 and the assembly groove 41. After the filler cures, the conductive plate 1 and the assembly groove 41 are connected as one unit, and the corresponding gaps are sealed.

[0049] Furthermore, a positioning platform is provided around the perimeter of the assembly slot 41, which is used to support and position the perimeter edges of the conductive plate 1.

[0050] Specifically, the positioning platform in the assembly groove 41 is used to support the conductive plate 1 and raise the conductive plate 1 relative to the bottom of the assembly groove 41. On the one hand, this is to avoid large-area contact between the conductive plate 1 and the assembly groove 41, which would affect the conductivity of the conductive plate 1. On the other hand, it is to form a space between the bottom surface of the conductive plate 1 and the bottom of the assembly groove 41, which is used to facilitate the wiring of the cable connecting the conductive plate 1 and the output terminal 5 and to provide sufficient space for the injection of filler.

[0051] Example 2

[0052] An embodiment of the present invention provides a motor lead-out structure, comprising:

[0053] Conductive plate 1 is disposed in an assembly groove 41 constructed on the outer surface of motor housing 4, and conductive plate 1 is electrically connected to the output terminal 5 of the motor formed at the assembly groove 41; and

[0054] The cable outlet connector 2 is detachably mounted on the surface of the conductive plate 1 so that its position on the surface of the conductive plate 1 can be adjusted. The conductive part of the cable outlet connector 2 is in contact with and electrically connected to the surface of the conductive plate 1.

[0055] Specifically, the conventional motor's cable exit structure is located at the top of the motor, meaning a connector is fixed to the top of the motor housing 4 using bolts or welding. This method often results in a relatively large size because it requires sufficient assembly space for the bolts or welds. Furthermore, this connection method is limited by the position of the internal cable exit terminal 5 of the motor; the position of the connector that needs to connect to terminal 5 cannot be adjusted. Therefore, the application of motors with conventional cable exit structures is restricted in some scenarios. For example, servo motors are widely used in various compact robotic devices, but the current size and relative position of the servo motor's cable exit structure may not meet the assembly requirements of some robots with limited assembly space.

[0056] To address the above problems, this embodiment proposes a motor cable output structure, as shown in the attached drawings. Figures 1 to 5 First, a mounting slot 41 is made on the top of the motor housing 4, as shown in the attached diagram. Figure 3 As shown, the size of the area covered by the assembly slot 41 is preferably matched with the area of ​​the top region of the motor housing 4, and the original position of the motor's output terminal 5 also corresponds to the position within the assembly slot 41. Then, a conductive plate 1 matching the size of the assembly slot 41 is installed in the assembly slot 41, and the terminals 12 on the conductive plate 1 are electrically connected to the output terminal 5 via cables. Finally, an output connector 2 is installed on the surface of the conductive plate 1, and the output connector 2 is detachably connected to the surface of the conductive plate 1; in the connected state, the conductive part of the output connector 2 contacts the surface of the conductive plate 1 and achieves electrical connection.

[0057] The cable outlet structure of the present invention utilizes a conductive plate 1 to provide a mounting surface for the cable outlet connector 2. In this way, the cable outlet connector 2 can adjust its relative position on the conductive plate 1 surface at any time according to the assembly space conditions of the corresponding equipment through a detachable connection method, thereby meeting the assembly requirements of the corresponding equipment.

[0058] Preferably, the cable outlet connector 2 is magnetically connected to the surface of the conductive plate 1, and the conductive plate 1 is made of magnetic material or has multiple magnetically attached parts 11 made of magnetic material embedded on its surface.

[0059] Specifically, there are various ways to detachably connect the cable outlet connector 2 to the surface of the conductive plate 1. For example, snap-fit ​​structures can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through the snap-fit ​​structures; alternatively, screw holes can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through bolts.

[0060] For magnetic connections, the entire conductive plate 1 can be supported by a conductive magnetic material, and the part of the wire connector 2 that contacts the conductive plate 1 can also be made of magnetic material. This allows the wire connector 2 to be positioned arbitrarily on the surface of the conductive plate 1.

(See attached figure.) Figure 1 As shown, four magnetic suction parts 11 are provided in an area corresponding to the outgoing connector 2.

[0061] Furthermore, the output terminal 5 is located inside the assembly groove 41 and at one end of the assembly groove 41, and the output terminal 5 is electrically connected to the side or bottom surface of the conductive plate 1 through a connecting wire.

[0062] Specifically, as shown in the attached diagram. Figure 2 and Figure 3 As shown, the output terminal 5 is located at one end inside the assembly slot 41. When the output terminal 5 is connected to the conductive plate 1, it can be connected to the side of the conductive plate 1 or to the bottom surface of the conductive plate 1 (the conductive plate 1 covers the output terminal 5). In this embodiment, it is preferred to connect the output terminal 5 to the bottom surface of the conductive plate 1. Corresponding terminals 12 are provided on the bottom surface of the conductive plate 1, as shown in the attached figure. Figure 4 As shown; compared to connecting to the side and the output terminal 5, the bottom connection method allows the conductive plate 1 to have a larger area, thus providing more options for the output connector 2.

[0063] Furthermore, the bottom of the assembly groove 41 is constructed with a terminal groove 411 at the location of the outgoing terminal 5, and the outgoing terminal 5 is disposed in the terminal groove 411 and is completely located within the terminal groove 411.

[0064] Specifically, as shown in the attached diagram. Figure 3 As shown, the outgoing terminal 5 is disposed within the terminal slot 411, thus the outgoing terminal 5 does not actually occupy the space of the assembly slot 41, thereby leaving space for the connecting cable between the outgoing terminal 5 and the conductive plate 1. Furthermore, the size of the conductive plate 1 can be designed to match the assembly slot 41, increasing the area of ​​the conductive plate 1, and thus allowing the bottom surface of the conductive plate 1 to be connected to the outgoing terminal 5.

[0065] Furthermore, the conductive plate 1 is provided with a filling hole for injecting filler into the assembly groove 41. The filler is used to seal the gap between the conductive plate 1 and the assembly groove 41 and to connect the conductive plate 1 and the assembly groove 41 into one piece.

[0066] Specifically, after the conductive plate 1 is installed into the assembly groove 41, there is only a relative positional constraint between the two, but they are not completely fixed, and there are some gaps between them. Therefore, further fixing and electrical sealing are required. In this embodiment, filler (such as epoxy resin) is injected into the assembly groove 41 through the filling hole on the conductive plate 1. After the filler enters the assembly groove 41, it will further fill the gaps between the conductive plate 1 and the assembly groove 41. After the filler cures, the conductive plate 1 and the assembly groove 41 are connected as one unit, and the corresponding gaps are sealed.

[0067] Furthermore, a positioning platform is provided around the perimeter of the assembly slot 41, which is used to support and position the perimeter edges of the conductive plate 1.

[0068] Specifically, the positioning platform in the assembly groove 41 is used to support the conductive plate 1 and raise the conductive plate 1 relative to the bottom of the assembly groove 41. On the one hand, this is to avoid large-area contact between the conductive plate 1 and the assembly groove 41, which would affect the conductivity of the conductive plate 1. On the other hand, it is to form a space between the bottom surface of the conductive plate 1 and the bottom of the assembly groove 41, which is used to facilitate the wiring of the cable connecting the conductive plate 1 and the output terminal 5 and to provide sufficient space for the injection of filler.

[0069] Furthermore, the cable outlet structure also includes a sealing cover 3 covering the assembly groove 41. The sealing cover 3 is used to close the assembly groove 41. The sealing cover 3 has multiple connection ports 31 that correspond to different positions on the surface of the conductive plate 1. The cable outlet connector 2 is connected to the surface of the conductive plate 1 through the connection ports 31.

[0070] Specifically, as shown in the attached diagram. Figure 1 and Figure 2 As shown, the cable outlet structure in this embodiment further includes a sealing cover 3. The sealing cover 3 is used to seal the assembly groove 41 after the conductive plate 1 is installed into the assembly groove 41, thereby isolating the assembly groove 41, the conductive plate 1, and the outside environment. The sealing cover 3 has multiple connection ports 31, and the bottom of the cable outlet connector 2 can be placed in the corresponding connection port 31 to connect with the surface of the conductive plate 1. The distribution and number of the connection ports 31 are consistent with the detachable connection structures provided on the conductive plate 1. For example, in this embodiment, a magnetic connection is used, and the number and distribution of the connection ports 31 are the same as the number and distribution of the magnetic areas formed by the magnetic attraction part 11 on the conductive plate 1.

[0071] Furthermore, since the conductive plate 1 generates heat during use, the sealing cover 3 is made of a high-temperature resistant insulating material, such as PC engineering plastic. The temperature rise during motor operation is 91K (taking a 180 model motor as an example, insulation class F, room temperature 23℃), which translates to a temperature of 114℃. PC engineering plastic has a usable temperature range of -40℃ to 135℃, therefore, PC engineering plastic can meet the motor's operating conditions and is relatively lightweight, thus enhancing the motor's lightweight characteristics to a certain extent.

[0072] Preferably, the multiple connection ports 31 are arranged in an array on the sealing cover 3.

[0073] Furthermore, the sealing cover 3 includes a plurality of sub-covers 32, which can be placed on the connection port 31 to seal the corresponding connection port 31 that is not mated with the outgoing connector 2.

[0074] Specifically, as shown in the figure Figure 1 As shown, the sub-cover 32 can seal the connection port 31, isolating the connection port 31 from the external environment. All connection ports 31 that do not mate with the outlet connector 2 are sealed by the sub-cover 32. The sub-cover 32 can be fixed to the connection port 31 by hinged one side of the sub-cover 32 to one side of the edge of the connection port 31, so that the sub-cover 32 is always connected to the connection port 31 and the corresponding connection port 31 can be opened and closed by flipping it; or the sub-cover 32 can be magnetically connected to the edge of the connection port 31 by a magnetic strip, so that when the corresponding connection port 31 needs to mate with the outlet connector 2, the sub-cover 32 can be directly removed from the connection port 31.

[0075] Furthermore, the conductive plate 1 is covered with an insulating layer around its perimeter, which isolates the conductive plate 1 from contact with the assembly groove 41 and the sealing cover 3.

[0076] Specifically, since the conductive plate 1 is the intermediate conductor of the motor output structure, its conductivity directly affects the motor performance. Therefore, in order to avoid short circuits caused by direct contact between the conductive plate 1 and the assembly groove 41 and the sealing cover 3, an insulating layer (for example, formed by wrapping with thin rubber) is covered around the edges of the conductive plate 1 to isolate the conductive plate 1 from direct contact with other components.

[0077] Example 3

[0078] This embodiment is an improvement on embodiment 2. Some of the same content is the same as in embodiment 2, and will not be repeated in this embodiment.

[0079] An embodiment of the present invention provides a motor lead-out structure, comprising:

[0080] Conductive plate 1 is disposed in an assembly groove 41 constructed on the outer surface of motor housing 4, and conductive plate 1 is electrically connected to the output terminal 5 of the motor formed at the assembly groove 41; and

[0081] The cable outlet connector 2 is detachably mounted on the surface of the conductive plate 1 so that its position on the surface of the conductive plate 1 can be adjusted. The conductive part of the cable outlet connector 2 is in contact with and electrically connected to the surface of the conductive plate 1.

[0082] Specifically, the conventional motor's cable exit structure is located at the top of the motor, meaning a connector is fixed to the top of the motor housing 4 using bolts or welding. This method often results in a relatively large size because it requires sufficient assembly space for the bolts or welds. Furthermore, this connection method is limited by the position of the internal cable exit terminal 5 of the motor; the position of the connector that needs to connect to terminal 5 cannot be adjusted. Therefore, the application of motors with conventional cable exit structures is restricted in some scenarios. For example, servo motors are widely used in various compact robotic devices, but the current size and relative position of the servo motor's cable exit structure may not meet the assembly requirements of some robots with limited assembly space.

[0083] To address the above problems, this embodiment proposes a motor cable output structure, as shown in the attached drawings. Figures 1 to 5 First, a mounting slot 41 is made on the top of the motor housing 4, as shown in the attached diagram. Figure 3 As shown, the size of the area covered by the assembly slot 41 is preferably matched with the area of ​​the top region of the motor housing 4, and the original position of the motor's output terminal 5 also corresponds to the position within the assembly slot 41. Then, a conductive plate 1 matching the size of the assembly slot 41 is installed in the assembly slot 41, and the terminals 12 on the conductive plate 1 are electrically connected to the output terminal 5 via cables. Finally, an output connector 2 is installed on the surface of the conductive plate 1, and the output connector 2 is detachably connected to the surface of the conductive plate 1; in the connected state, the conductive part of the output connector 2 contacts the surface of the conductive plate 1 and achieves electrical connection.

[0084] The cable outlet structure of the present invention utilizes a conductive plate 1 to provide a mounting surface for the cable outlet connector 2. In this way, the cable outlet connector 2 can adjust its relative position on the conductive plate 1 surface at any time according to the assembly space conditions of the corresponding equipment through a detachable connection method, thereby meeting the assembly requirements of the corresponding equipment.

[0085] Furthermore, the cable outlet structure also includes a sealing cover 3 covering the assembly groove 41. The sealing cover 3 is used to close the assembly groove 41. The sealing cover 3 has multiple connection ports 31 that correspond to different positions on the surface of the conductive plate 1. The cable outlet connector 2 is connected to the surface of the conductive plate 1 through the connection ports 31.

[0086] Specifically, as shown in the attached diagram. Figure 1 and Figure 2As shown, the cable outlet structure in this embodiment further includes a sealing cover 3. The sealing cover 3 is used to seal the assembly groove 41 after the conductive plate 1 is installed into the assembly groove 41, thereby isolating the assembly groove 41, the conductive plate 1, and the outside environment. The sealing cover 3 has multiple connection ports 31, and the bottom of the cable outlet connector 2 can be placed in the corresponding connection port 31 to connect with the surface of the conductive plate 1. The distribution and number of the connection ports 31 are consistent with the detachable connection structures provided on the conductive plate 1. For example, in this embodiment, a magnetic connection is used, and the number and distribution of the connection ports 31 are the same as the number and distribution of the magnetic areas formed by the magnetic attraction part 11 on the conductive plate 1.

[0087] Furthermore, since the conductive plate 1 generates heat during use, the sealing cover 3 is made of a high-temperature resistant insulating material, such as PC engineering plastic. The temperature rise during motor operation is 91K (taking a 180 model motor as an example, insulation class F, room temperature 23℃), which translates to a temperature of 114℃. PC engineering plastic has a usable temperature range of -40℃ to 135℃, therefore, PC engineering plastic can meet the motor's operating conditions and is relatively lightweight, thus enhancing the motor's lightweight characteristics to a certain extent.

[0088] Furthermore, the sealing cover 3 is provided with a heat dissipation mechanism, which includes one or more of the following: heat dissipation ribs 33 constructed on the outer surface of the sealing cover 3, air-cooling components disposed on the sealing cover 3, and liquid-cooling components disposed on the sealing cover 3.

[0089] Specifically, as shown in the attached diagram. Figure 1 As shown, in this embodiment, multiple heat dissipation ribs 33 are machined on the outer surface of the sealing cover 3 to increase the contact area with air and thus achieve heat dissipation. Alternatively, other heat dissipation components such as air cooling or liquid cooling can be used or added.

[0092] Conductive plate 1 is disposed in an assembly groove 41 constructed on the outer surface of motor housing 4, and conductive plate 1 is electrically connected to the output terminal 5 of the motor formed at the assembly groove 41; and

[0093] The cable outlet connector 2 is detachably mounted on the surface of the conductive plate 1 so that its position on the surface of the conductive plate 1 can be adjusted. The conductive part of the cable outlet connector 2 is in contact with and electrically connected to the surface of the conductive plate 1.

[0094] Specifically, the conventional motor's cable exit structure is located at the top of the motor, meaning a connector is fixed to the top of the motor housing 4 using bolts or welding. This method often results in a relatively large size because it requires sufficient assembly space for the bolts or welds. Furthermore, this connection method is limited by the position of the internal cable exit terminal 5 of the motor; the position of the connector that needs to connect to terminal 5 cannot be adjusted. Therefore, the application of motors with conventional cable exit structures is restricted in some scenarios. For example, servo motors are widely used in various compact robotic devices, but the current size and relative position of the servo motor's cable exit structure may not meet the assembly requirements of some robots with limited assembly space.

[0095] To address the above problems, this embodiment proposes a motor cable output structure, as shown in the attached drawings. Figures 1 to 5 First, a mounting slot 41 is made on the top of the motor housing 4, as shown in the attached diagram. Figure 3 As shown, the size of the area covered by the assembly slot 41 is preferably matched with the area of ​​the top region of the motor housing 4, and the original position of the motor's output terminal 5 also corresponds to the position within the assembly slot 41. Then, a conductive plate 1 matching the size of the assembly slot 41 is installed in the assembly slot 41, and the terminals 12 on the conductive plate 1 are electrically connected to the output terminal 5 via cables. Finally, an output connector 2 is installed on the surface of the conductive plate 1, and the output connector 2 is detachably connected to the surface of the conductive plate 1; in the connected state, the conductive part of the output connector 2 contacts the surface of the conductive plate 1 and achieves electrical connection.

[0096] The cable outlet structure of the present invention utilizes a conductive plate 1 to provide a mounting surface for the cable outlet connector 2. In this way, the cable outlet connector 2 can adjust its relative position on the conductive plate 1 surface at any time according to the assembly space conditions of the corresponding equipment through a detachable connection method, thereby meeting the assembly requirements of the corresponding equipment.

[0097] Preferably, the cable outlet connector 2 is magnetically connected to the surface of the conductive plate 1, and the conductive plate 1 is made of magnetic material or has multiple magnetically attached parts 11 made of magnetic material embedded on its surface.

[0098] Specifically, there are various ways to detachably connect the cable outlet connector 2 to the surface of the conductive plate 1. For example, snap-fit ​​structures can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through the snap-fit ​​structures; alternatively, screw holes can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through bolts. In this embodiment, a magnetic connection is preferably used between the cable outlet connector 2 and the surface of the conductive plate 1, which allows for convenient adjustment of the connection position; furthermore, the magnetic connection eliminates the need for additional connecting components, significantly reducing the volume of the cable outlet connector 2 and the entire cable outlet structure.

[0099] For magnetic connections, the entire conductive plate 1 can be supported by a conductive magnetic material, and the part of the wire connector 2 that contacts the conductive plate 1 can also be made of magnetic material. This allows the wire connector 2 to be positioned arbitrarily on the surface of the conductive plate 1. Alternatively, considering the influence of magnetic materials on conductivity, multiple magnetic suction parts 11 made of magnetic material can be embedded in various locations on the non-magnetic conductive plate 1 (e.g., multiple magnetic blocks distributed in a copper plate). The part of the wire connector 2 that contacts the conductive plate 1 can also be made of magnetic material. This allows the wire connector 2 to be positioned between multiple predetermined areas (the areas where the magnetic suction parts 11 are distributed) on the surface of the conductive plate 1. (See attached figure.) Figure 1 As shown, four magnetic suction parts 11 are provided in an area corresponding to the outgoing connector 2.

[0100] Furthermore, the output terminal 5 is located inside the assembly groove 41 and at one end of the assembly groove 41, and the output terminal 5 is electrically connected to the side or bottom surface of the conductive plate 1 through a connecting wire.

[0101] Specifically, as shown in the attached diagram. Figure 2 and Figure 3 As shown, the output terminal 5 is located at one end inside the assembly slot 41. When the output terminal 5 is connected to the conductive plate 1, it can be connected to the side of the conductive plate 1 or to the bottom surface of the conductive plate 1 (the conductive plate 1 covers the output terminal 5). In this embodiment, it is preferred to connect the output terminal 5 to the bottom surface of the conductive plate 1. Corresponding terminals 12 are provided on the bottom surface of the conductive plate 1, as shown in the attached figure. Figure 4 As shown; compared to connecting to the side and the output terminal 5, the bottom connection method allows the conductive plate 1 to have a larger area, thus providing more options for the output connector 2.

[0102] Furthermore, the bottom of the assembly groove 41 is constructed with a terminal groove 411 at the location of the outgoing terminal 5, and the outgoing terminal 5 is disposed in the terminal groove 411 and is completely located within the terminal groove 411.

[0103] Specifically, as shown in the attached diagram. Figure 3 As shown, the outgoing terminal 5 is disposed within the terminal slot 411, thus the outgoing terminal 5 does not actually occupy the space of the assembly slot 41, thereby leaving space for the connecting cable between the outgoing terminal 5 and the conductive plate 1. Furthermore, the size of the conductive plate 1 can be designed to match the assembly slot 41, increasing the area of ​​the conductive plate 1, and thus allowing the bottom surface of the conductive plate 1 to be connected to the outgoing terminal 5.

[0104] Furthermore, the conductive plate 1 is provided with a filling hole for injecting filler into the assembly groove 41. The filler is used to seal the gap between the conductive plate 1 and the assembly groove 41 and to connect the conductive plate 1 and the assembly groove 41 into one piece.

[0105] Specifically, after the conductive plate 1 is installed into the assembly groove 41, there is only a relative positional constraint between the two, but they are not completely fixed, and there are some gaps between them. Therefore, further fixing and electrical sealing are required. In this embodiment, filler (such as epoxy resin) is injected into the assembly groove 41 through the filling hole on the conductive plate 1. After the filler enters the assembly groove 41, it will further fill the gaps between the conductive plate 1 and the assembly groove 41. After the filler cures, the conductive plate 1 and the assembly groove 41 are connected as one unit, and the corresponding gaps are sealed.

[0106] Furthermore, a positioning platform is provided around the perimeter of the assembly slot 41, which is used to support and position the perimeter edges of the conductive plate 1.

[0107] Specifically, the positioning platform in the assembly groove 41 is used to support the conductive plate 1 and raise the conductive plate 1 relative to the bottom of the assembly groove 41. On the one hand, this is to avoid large-area contact between the conductive plate 1 and the assembly groove 41, which would affect the conductivity of the conductive plate 1. On the other hand, it is to form a space between the bottom surface of the conductive plate 1 and the bottom of the assembly groove 41, which is used to facilitate the wiring of the cable connecting the conductive plate 1 and the output terminal 5 and to provide sufficient space for the injection of filler.

[0109] An embodiment of the present invention provides an electric motor, which includes a motor cable outlet structure, the motor cable outlet structure comprising:

[0110] Conductive plate 1 is disposed in an assembly groove 41 constructed on the outer surface of motor housing 4, and conductive plate 1 is electrically connected to the output terminal 5 of the motor formed at the assembly groove 41; and

[0111] The cable outlet connector 2 is detachably mounted on the surface of the conductive plate 1 so that its position on the surface of the conductive plate 1 can be adjusted. The conductive part of the cable outlet connector 2 is in contact with and electrically connected to the surface of the conductive plate 1.

[0113] To address the above problems, this embodiment proposes a motor cable output structure, as shown in the attached drawings. Figures 1 to 5 First, a mounting slot 41 is made on the top of the motor housing 4, as shown in the attached diagram. Figure 3 As shown, the size of the area covered by the assembly slot 41 is preferably matched with the area of ​​the top region of the motor housing 4, and the original position of the motor's output terminal 5 also corresponds to the position within the assembly slot 41.

[0114] The cable outlet structure of the present invention utilizes a conductive plate 1 to provide a mounting surface for the cable outlet connector 2. In this way, the cable outlet connector 2 can adjust its relative position on the conductive plate 1 surface at any time according to the assembly space conditions of the corresponding equipment through a detachable connection method, thereby meeting the assembly requirements of the corresponding equipment.

[0115] Preferably, the cable outlet connector 2 is magnetically connected to the surface of the conductive plate 1, and the conductive plate 1 is made of magnetic material or has multiple magnetically attached parts 11 made of magnetic material embedded on its surface.

[0116] Specifically, there are various ways to detachably connect the cable outlet connector 2 to the surface of the conductive plate 1. For example, snap-fit ​​structures can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through the snap-fit ​​structures; alternatively, screw holes can be provided at different positions on the surface of the conductive plate 1, and the cable outlet connector 2 can be connected to the conductive plate 1 through bolts.

(See attached figure.) Figure 1As shown, four magnetic suction parts 11 are provided in an area corresponding to the outgoing connector 2.

[0118] Furthermore, the output terminal 5 is located inside the assembly groove 41 and at one end of the assembly groove 41, and the output terminal 5 is electrically connected to the side or bottom surface of the conductive plate 1 through a connecting wire.

[0119] Specifically, as shown in the attached diagram. Figure 2 and Figure 3 As shown, the output terminal 5 is located at one end inside the assembly slot 41. When the output terminal 5 is connected to the conductive plate 1, it can be connected to the side of the conductive plate 1 or to the bottom surface of the conductive plate 1 (the conductive plate 1 covers the output terminal 5). In this embodiment, it is preferred to connect the output terminal 5 to the bottom surface of the conductive plate 1. Corresponding terminals 12 are provided on the bottom surface of the conductive plate 1, as shown in the attached figure. Figure 4 As shown; compared to connecting to the side and the output terminal 5, the bottom connection method allows the conductive plate 1 to have a larger area, thus providing more options for the output connector 2.

[0120] Furthermore, the bottom of the assembly groove 41 is constructed with a terminal groove 411 at the location of the outgoing terminal 5, and the outgoing terminal 5 is disposed in the terminal groove 411 and is completely located within the terminal groove 411.

[0121] Specifically, as shown in the attached diagram. Figure 3 As shown, the outgoing terminal 5 is disposed within the terminal slot 411, thus the outgoing terminal 5 does not actually occupy the space of the assembly slot 41, thereby leaving space for the connecting cable between the outgoing terminal 5 and the conductive plate 1. Furthermore, the size of the conductive plate 1 can be designed to match the assembly slot 41, increasing the area of ​​the conductive plate 1, and thus allowing the bottom surface of the conductive plate 1 to be connected to the outgoing terminal 5.

[0122] Furthermore, the conductive plate 1 is provided with a filling hole for injecting filler into the assembly groove 41. The filler is used to seal the gap between the conductive plate 1 and the assembly groove 41 and to connect the conductive plate 1 and the assembly groove 41 into one piece.

[0123] Specifically, after the conductive plate 1 is installed into the assembly groove 41, there is only a relative positional constraint between the two, but they are not completely fixed, and there are some gaps between them. Therefore, further fixing and electrical sealing are required. In this embodiment, filler (such as epoxy resin) is injected into the assembly groove 41 through the filling hole on the conductive plate 1. After the filler enters the assembly groove 41, it will further fill the gaps between the conductive plate 1 and the assembly groove 41. After the filler cures, the conductive plate 1 and the assembly groove 41 are connected as one unit, and the corresponding gaps are sealed.

[0124] Furthermore, a positioning platform is provided around the perimeter of the assembly slot 41, which is used to support and position the perimeter edges of the conductive plate 1.

[0125] Specifically, the positioning platform in the assembly groove 41 is used to support the conductive plate 1 and raise the conductive plate 1 relative to the bottom of the assembly groove 41. On the one hand, this is to avoid large-area contact between the conductive plate 1 and the assembly groove 41, which would affect the conductivity of the conductive plate 1. On the other hand, it is to form a space between the bottom surface of the conductive plate 1 and the bottom of the assembly groove 41, which is used to facilitate the wiring of the cable connecting the conductive plate 1 and the output terminal 5 and to provide sufficient space for the injection of filler.

[0126] Furthermore, the cable outlet structure also includes a sealing cover 3 covering the assembly groove 41. The sealing cover 3 is used to close the assembly groove 41. The sealing cover 3 has multiple connection ports 31 that correspond to different positions on the surface of the conductive plate 1. The cable outlet connector 2 is connected to the surface of the conductive plate 1 through the connection ports 31.

[0127] Specifically, as shown in the attached diagram. Figure 1 and Figure 2 As shown, the cable outlet structure in this embodiment further includes a sealing cover 3. The sealing cover 3 is used to seal the assembly groove 41 after the conductive plate 1 is installed into the assembly groove 41, thereby isolating the assembly groove 41, the conductive plate 1, and the outside environment. The sealing cover 3 has multiple connection ports 31, and the bottom of the cable outlet connector 2 can be placed in the corresponding connection port 31 to connect with the surface of the conductive plate 1. The distribution and number of the connection ports 31 are consistent with the detachable connection structures provided on the conductive plate 1. For example, in this embodiment, a magnetic connection is used, and the number and distribution of the connection ports 31 are the same as the number and distribution of the magnetic areas formed by the magnetic attraction part 11 on the conductive plate 1.

[0128] Furthermore, since the conductive plate 1 generates heat during use, the sealing cover 3 is made of a high-temperature resistant insulating material, such as PC engineering plastic. The temperature rise during motor operation is 91K (taking a 180 model motor as an example, insulation class F, room temperature 23℃), which translates to a temperature of 114℃. PC engineering plastic has a usable temperature range of -40℃ to 135℃, therefore, PC engineering plastic can meet the motor's operating conditions and is relatively lightweight, thus enhancing the motor's lightweight characteristics to a certain extent.

[0129] Preferably, the multiple connection ports 31 are arranged in an array on the sealing cover 3.

[0130] Furthermore, the sealing cover 3 includes a plurality of sub-covers 32, which can be placed on the connection port 31 to seal the corresponding connection port 31 that is not mated with the outgoing connector 2.

[0131] Specifically, as shown in the figure Figure 1As shown, the sub-cover 32 can seal the connection port 31, isolating the connection port 31 from the external environment. All connection ports 31 that do not mate with the outlet connector 2 are sealed by the sub-cover 32. The sub-cover 32 can be fixed to the connection port 31 by hinged one side of the sub-cover 32 to one side of the edge of the connection port 31, so that the sub-cover 32 is always connected to the connection port 31 and the corresponding connection port 31 can be opened and closed by flipping it; or the sub-cover 32 can be magnetically connected to the edge of the connection port 31 by a magnetic strip, so that when the corresponding connection port 31 needs to mate with the outlet connector 2, the sub-cover 32 can be directly removed from the connection port 31.

[0132] Furthermore, the conductive plate 1 is covered with an insulating layer around its perimeter, which isolates the conductive plate 1 from contact with the assembly groove 41 and the sealing cover 3.

[0133] Specifically, since the conductive plate 1 is the intermediate conductor of the motor output structure, its conductivity directly affects the motor performance. Therefore, in order to avoid short circuits caused by direct contact between the conductive plate 1 and the assembly groove 41 and the sealing cover 3, an insulating layer (for example, formed by wrapping with thin rubber) is covered around the edges of the conductive plate 1 to isolate the conductive plate 1 from direct contact with other components.

[0134] Furthermore, the sealing cover 3 is provided with a heat dissipation mechanism, which includes one or more of the following: heat dissipation ribs 33 constructed on the outer surface of the sealing cover 3, air-cooling components disposed on the sealing cover 3, and liquid-cooling components disposed on the sealing cover 3.

[0135] Specifically, as shown in the attached diagram. Figure 1 As shown, in this embodiment, multiple heat dissipation ribs 33 are machined on the outer surface of the sealing cover 3 to increase the contact area with air and thus achieve heat dissipation. Alternatively, other heat dissipation components such as air cooling or liquid cooling can be used or added.
