Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a connection structure between a motor and an electronic control, and a suspension motor. Background Art

[0002] In existing chassis and suspension systems, the motor is a key power output component, and its three-phase terminals typically need to establish a stable electrical connection with the motor windings to achieve motor control and power transmission. These terminals are typically made of steel-clad copper, with the copper core providing conductivity and the steel shell providing mechanical strength and protection. The circuit board that connects to the motor windings typically has wiring holes made of copper or other conductive materials. During assembly, the wiring holes are typically soldered to the three-phase terminals to ensure good contact.

[0003] However, when welding three-phase terminal blocks and copper terminal holes made of steel-clad copper, on the one hand, the welding assembly process is inefficient. Welding not only requires precise control of temperature and time, but also requires professional welding equipment and well-trained operators, which increases production costs and assembly time. On the other hand, due to the differences in melting points, thermal expansion coefficients and electrochemical properties of steel and copper, defects such as cracks, pores and incomplete penetration are easily generated during the welding process. These defects will reduce the mechanical strength and conductive properties of the connection, affecting the reliability and efficiency of the motor. Utility Model Content

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The present invention provides a connection structure 100 between a motor and an electronic control.

[0041] See also Figures 1 to 3 In one embodiment of the present invention, the electric control has a three-phase output terminal 1, the winding 8 of the motor is electrically connected to the circuit board 2, and the connection structure 100 between the motor and the electric control also includes a conductive component 3, which is electrically connected to the circuit board 2. The three-phase output terminal 1 is plugged into the conductive component 3 to achieve circuit connectivity between the three-phase output terminal 1 and the winding 8.

[0042] The present invention adopts a plug-in matching method so that the three-phase terminal 7 of the motor can be plugged into the conductive component 3 through the three-phase outlet terminal 1 of the electric control. Specifically, during the assembly process, the conductive component 3 is first installed on the circuit board 2 to ensure its accurate position so that the three-phase terminal 7 of the motor can be introduced into the three-phase outlet terminal 1 of the electric control and positioned next to the conductive component 3 on the circuit board 2. Finally, the three-phase outlet terminal 1 of the electric control is plugged into the conductive component 3. The above assembly method, on the one hand, eliminates the need for precise control of temperature and time in the traditional welding process, simplifies the assembly steps, and thus significantly improves the connection efficiency between the motor and the controller. On the other hand, because plug-in matching does not require expensive welding equipment and professional welding operators, it can reduce production costs and dependence on professional skills.

[0043] The motor includes a casing 4, a cavity 41 is formed inside the casing 4, an outer wall of the casing 4 is provided with an opening connected to the cavity 41, and the winding 8 and the conductive component 3 are accommodated in the cavity 41; part of the structure of the three-phase output terminal 1 extends into the cavity 41 from the opening; the circuit board 2 is electrically connected to the winding 8; the connection structure 100 between the motor and the electronic control also includes an insulating seal 5, which is arranged between the cavity wall of the cavity 41 and the three-phase output terminal 1, and is used to seal the gap between the casing 4 and the three-phase output terminal 1.

[0044] In motor design, to isolate the stator and rotor to enhance insulation, a lining is often added to the inner diameter of the stator and the rotor is immersed in hydraulic fluid. This design improves motor cooling efficiency, but it also increases the electromagnetic air gap (the gap or distance between the motor's rotor and stator), thereby affecting motor output. To address this issue, a common approach is to increase the stack height—increasing the axial length of the motor—to maintain the electromagnetic air gap within an acceptable range. However, this approach increases the motor's size, potentially making it unsuitable for space-constrained applications. To address the above-mentioned issues, in one embodiment of the present application, a motor includes a housing 4, wherein a cavity 41 is formed within the housing 4. An opening is formed on the outer wall of the housing 4, communicating with the cavity 41. The winding 8 and the conductive component 3 are accommodated within the cavity 41. Part of the structure of the three-phase output terminal 1 extends from the opening into the cavity 41. The circuit board 2 is electrically connected to the winding 8. The connection structure 100 between the motor and the electronic control further includes an insulating seal 5, which is disposed between the cavity wall of the cavity 41 and the three-phase output terminal 1 and is used to seal the gap between the housing 4 and the three-phase output terminal 1. In the above-mentioned embodiment, the three-phase output terminal 1 and the housing 4 are sealed by the insulating seal 5. That is, the oil inside the motor is isolated from the outside by the insulating seal 5, so that both the stator and rotor of the motor are immersed in hydraulic oil. This eliminates the need for a liner design, allowing the rotor to be closer to the stator winding 8 of the motor, thereby reducing the stack height of the motor, shortening the axial length of the motor, and thus reducing the total volume of the motor.

[0045] Furthermore, in one embodiment of the present application, the insulating seal 5 is a glass sinter 5a. The glass sinter 5a material has excellent insulation properties and can maintain stable electrical insulation properties under high temperature and high pressure environments. The sintering process can form a very stable structure that is not easy to deform, which is crucial for maintaining accurate air gap size and motor performance. During actual production and processing, the sintered glass can be pre-processed into a sleeve-shaped structure with a plug-in channel. During assembly, the sleeve-shaped glass sinter 5a is inserted into the cavity 41 through the opening, and the three-phase output terminal 1 of the electric control is inserted into the plug-in channel of the glass sinter 5a to extend into the cavity 41 of the housing 4. The plug-in process needs to ensure that the connection between the output terminal and the glass sinter 5a is tight and stable to ensure good electrical connection and insulation performance, thereby ensuring the isolation of the oil inside the motor from the external environment, thereby improving the reliability and service life of the motor. In other embodiments, there are multiple options for the material and structure of the insulating seal 5, such as ceramic materials or silicone rubber materials, etc. However, it should be noted that when selecting the material of the insulating seal 5, the following conditions must be met: the insulating seal 5 must be able to maintain its performance within the normal operating temperature range of the motor, and the sealing material must be compatible with the oil and other chemicals used in the motor. In addition, the insulating seal 5 needs to have a certain strength to withstand mechanical stress and vibration, and its material must have good electrical insulation properties to prevent leakage.

[0046] In the motor structure, the end caps are usually located at both ends of the motor, opposite to the shaft end of the motor, and are used to seal the non-drive end or the drive end of the motor and protect internal components such as the stator, rotor, bearings and coils; while the base plate 6 is usually located at the bottom of the motor, mainly used to support the weight of the entire motor and serve as the basis for installing the motor on the equipment or bracket. Based on the above structure, in one embodiment of the present application, the motor also includes a base plate 6, which is provided on the side of the housing 4 where the opening is provided, and the base plate 6 has a through hole, which is connected to the opening; part of the structure of the three-phase outlet terminal 1 extends from the through hole into the cavity 41; the insulating seal 5 is also provided between the hole wall of the through hole and the outer wall of the three-phase outlet terminal 1, and is used to seal the gap between the base plate 6 and the three-phase outlet terminal 1. In the above embodiment, the base plate 6 is glass-sintered 5a because it is heat-resistant, resistant to expansion and leakage, and maintains a stable seal. However, the end caps are generally less heat-resistant and easily expand, leading to leakage. Of course, if the end caps are made of a high-temperature-resistant material, the three-phase outlet terminals 1 and the end caps can also be glass-sintered 5a to achieve the same sealing and insulation effect. This design takes into account the performance requirements of the motor under different operating conditions and ensures the reliability and long-term stable operation of the motor.

[0047] In one embodiment of the present application, the motor further comprises a sealing pad, which is arranged between the base plate 6 and the casing 4. In the design of the motor, the sealing pad is an important component, which is used to ensure the sealing inside the motor, prevent the external environment (such as dust, moisture, etc.) from entering the inside of the motor, and also prevent the internal grease or cooling medium from leaking. The sealing pad is usually located on the joint surface between the base plate 6 and the casing 4. When the motor is assembled, the sealing pad is pressed between the base plate 6 and the casing 4 to form a sealing barrier to prevent the internal oil or coolant and other media from leaking to the outside of the motor. It should be noted that the shape and material of the sealing pad can be selected according to its specific application and required function in the motor. For example, the sealing pad can be a flat pad or an O-type pad, and its material selection can be rubber or a composite material with rubber or other materials that can be used for sealing and are resistant to high temperatures.

[0048] Since the dimension chain between the three-phase power terminal of the motor and the three-phase wiring hole 312 of the circuit board 2 is long, this leads to a large centering deviation, resulting in poor performance of direct mounting, and prone to poor contact or unstable connection, affecting the reliability and durability of the entire system. Therefore, in one embodiment of the present application, the conductive component 3 includes a base 31 and a conductive member 32, the base 31 is formed with a wiring hole 312 inside, the outer wall of the base 31 is provided with a wiring port connected to the wiring hole 312, and the three-phase output terminal 1 is plugged into the wiring hole 312 from the wiring port; the conductive member 32 is accommodated in the wiring hole 312, and the conductive member 32 includes a copper terminal 321a, an elastic member 322a and a contact piece 323a; one end of the copper terminal 321a is electrically connected to the circuit board 2; the elastic member 322a is electrically connected to the copper terminal 321a; the contact piece 323a is arranged near the wiring port and is electrically connected to the elastic member 322a, and the contact piece 323a is in contact with the three-phase output terminal 1. By using a spring member 322a with a contact piece 323a to electrically connect to the copper terminal 321a, the reliability and stability of the wiring connection are ensured. Specifically, the contact piece 323a and the three-phase output terminal 1 are connected in a top-to-top manner. The spring can provide a compressive force during the top-to-top contact process, allowing the conductive component 3 to provide a higher connection stability. This improvement not only improves the reliability of the electrical connection, but also enhances the stability and durability of the entire connection structure.

[0049] In one embodiment of the present application, the wiring hole 312 includes a mounting slot 3121 and a countersunk slot 3122 communicating with the mounting slot 3121. The wiring port communicates with the mounting slot 3121. A portion of the copper terminal 321a is positioned and inserted within the countersunk slot 3122, and the elastic member 322a is connected to the end of the copper terminal 321a away from the countersunk slot 3122. A portion of the copper terminal 321a is designed to be inserted and retained within the countersunk slot 3122, ensuring the terminal's correct position within the mounting slot 3121, thereby ensuring a stable and reliable electrical connection. It should be noted that the size and shape of the mounting groove match the copper terminal 321a to ensure that the copper terminal 321a can be firmly installed therein. The function of the countersunk groove 3122 is to limit the vertical movement of the copper terminal 321a, thereby maintaining its correct position in the mounting groove 3121. When designing these structures, it is necessary to ensure the dimensional accuracy of the mounting groove 3121 and the countersunk groove 3122 to adapt to the size of the copper terminal 321a. The selection and installation position of the elastic member 322a need to ensure sufficient pressure to maintain the connection, but not to cause damage to the terminal or wire.

[0050] In one embodiment of the present application, a copper terminal 321a includes an insertion section 3211, a retaining section 3212, and a mounting section 3213, which are sequentially connected. The insertion section 3211 is retained and inserted into the countersunk groove 3122, while the mounting section 3213 and the retaining section 3212 are accommodated in the mounting groove 3121. The retaining section 3212 has a larger cross-sectional area than the insertion section 3211. An elastic member 322a is connected to the mounting section 3213. It should be noted that the size and shape of the insertion section 3211 must precisely match the countersunk groove 3122 to ensure a stable mechanical connection, while the retaining section 3212 prevents the copper terminal 321a from excessive movement or falling out of the countersunk groove 3122. The above structure of the copper terminal 321a enables the copper terminal 321a to form a stable and reliable mechanical connection with the countersunk groove 3122, while the elastic member 322a provides additional electrical connection reliability.

[0051] In one embodiment of the present application, the elastic member 322a includes a conductive spring, one end of which is sleeved on the outside of the copper terminal 321a and fixedly connected to the copper terminal 321a. The conductive spring can maintain good contact even in the case of vibration or impact, reducing the direct impact of the docking between the contact piece 323a and the contact terminal. In other embodiments, the elastic member 322a can also be a conductive material such as conductive rubber, conductive silicone or conductive polymer, etc., with good elastic and conductive properties. In different environments, the elastic member 322a can be made of different materials. For example, a conductive spring has advantages in applications that require high mechanical strength, good electrical properties and wide temperature adaptability, while conductive rubber is more suitable in applications that require good flexibility, sealing performance and cost-effectiveness.

[0052] In one embodiment of the present application, the connection structure 100 between the motor and the electronic control further includes a welding layer, which is disposed between the conductive spring and the contact piece 323a. Specifically, the contact piece 323a is a conductive steel sheet, which can provide a stable electrical connection and withstand certain mechanical stresses. The welding layer can be made of tin, silver, or other conductive welding materials. The use of the conductive steel sheet and the welding material can provide a stable electrical connection, ensuring good contact between the contact points. By using the welding material between the conductive spring and the conductive steel sheet, a more stable electrical connection and higher mechanical strength can be achieved between the three-phase terminal 7 and the circuit press.

[0053] Furthermore, in one embodiment of the present application, the cross-sectional area of the contact piece 323a is larger than the cross-sectional area of the copper terminal 321a. The larger contact area between the contact piece 323a and the copper terminal 321a provides a more stable electrical connection. On the one hand, the larger contact area and the combination of the elastic member 322a enable the conductive component 3 to provide greater alignment redundancy and connection stability. On the other hand, it can also reduce the increase in resistance and arcing caused by poor contact.

[0054] In one embodiment of the present application, the conductive assembly 3 includes a base 31 and a conductive member 32. A wiring hole 312 is formed within the base 31. A wiring port connected to the wiring hole 312 is defined on the outer wall of the base 31. The three-phase output terminal 1 is plugged into the wiring hole 312 from the wiring port. A pin portion 311 is defined on the outer wall of the base 31 for electrical connection to the circuit board 2. The conductive member 32 is received within the wiring hole 312. One end of the conductive member 32 defines a snap-in slot for snapping onto the three-phase output terminal 1. It should be noted that the size and shape of the snap-in slot must match those of the three-phase output terminal 1 to ensure stable insertion and a good electrical connection. The function of the lead adhesive is to contact the circuit board 2, thereby transmitting the motor's electrical signals to other electronic components or a control system on the circuit board 2, thereby achieving electrical connection with the motor winding 8. The pin portion 311 may be designed with a spring contact, solder point, pin, or other contact element to form a reliable electrical connection with a corresponding contact point (e.g., a pad, jack, etc.) on the circuit board 2.

[0055] In one embodiment, the conductive member 32 includes multiple elastic arms, each of which is connected at one end and together forms a snap-fitting slot. The design of the elastic arms allows the conductive member 32 to accommodate three-phase terminals 7 of varying sizes and shapes, facilitating abutment and locking the three-phase terminals 7 within the snap-fitting slot. The elastic arms also facilitate easy insertion and removal, simplifying installation and maintenance.

[0056] The present application also provides a suspension motor 1000, including the above-mentioned motor and electronic control connection structure 100, wherein the specific structure of the motor and electronic control connection structure 100 refers to the above-mentioned embodiment. Since the suspension motor 1000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
