Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure to fall within the scope of this application.

[0038] An inverter can convert variable direct current into alternating current of a certain frequency, reduce the volatility and randomness of the voltage, and maintain the stability of the output voltage of the cable.

[0039] When the circuit structure in the inverter needs to be connected to the cable, it is usually necessary to install a connecting piece (also called a connector), and connect and fix the cable to the circuit structure in the inverter through the connecting piece. However, the traditional connecting piece cannot meet the current usage requirements and urgently needs to be improved.

[0040] In view of the deficiencies in the related art, the present application provides a connection structure and an electromechanical device, which can solve the problem of inability to determine the rotation angle in the related art and can maintain a relatively fixed state at a specified angle. The detailed content will be described in the following embodiments.

[0041] According to some embodiments, the present application provides a connection structure. Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of the connection structure 100. The connection structure 100 may specifically include, for example, Figure 2 the spherical joint rotor 110 shown in Figure 3 , and, for example, Figure 4 the joint stator 120 shown in Figure 4 . Among them, at least a part of the outer surface of the spherical joint rotor 110 is provided with a plurality of protruding stop clamping points 110a; the internal shape of the joint stator 120 is configured as a spherical inner surface, and the spherical inner surface is matched with the shape of the spherical joint rotor 110 to enable the spherical joint rotor 110 to rotate in all directions within the joint stator 120. Please refer to

[0042] Specifically, please continue to refer to Figure 2 and Figure 3 , the spherical inner surface may be provided with a stop clamping groove 120a that cooperates with the stop clamping point 110a, and the stop clamping groove 120a is used for snap-fit connection with the stop clamping point 110a to keep the spherical joint rotor 110 and the joint stator 120 relatively fixed.

[0043] By adopting the above connection structure 100, by providing a plurality of protruding stop clamping points 110a on the outer surface of the spherical joint rotor 110 and corresponding stop clamping grooves 120a on the spherical inner surface of the joint stator 120, it is realized that the spherical joint rotor 110 can have an obvious jamming position after rotating a certain angle, so that the operator can judge whether the current spherical joint rotor 110 has reached a specific rotation angle by feeling the jamming.

[0044] When the spherical joint rotor 110 rotates to a certain specific angle, the stop point 110a will enter the stop slot 120a, thereby generating an obvious resistance. The reaction force of this resistance can be used as the docking force of the connection structure 100. If further rotation is continued, a greater torque is required to overcome this docking force. Therefore, during the operation process, the operator can intuitively feel that the spherical joint rotor 110 has reached a specific rotation angle through the change of this resistance, thus solving the problem in the related art that the rotation angle cannot be determined.

[0045] For example, when the stop point 110a enters the stop slot 120a, an obvious sense of jamming or clicking will be generated. This perception feedback is very intuitive and enables the operator to immediately judge whether the spherical joint rotor 110 has reached the predetermined rotation angle.

[0046] It can be understood that by arranging a plurality of stop points 110a on the outer surface of the spherical joint rotor 110 and corresponding stop slots 120a on the spherical inner surface of the joint stator 120, multi-point position limitation can be achieved; that is: multiple jamming points will be generated within the rotatable range of the spherical joint rotor 110, and each jamming point can correspond to a specific rotation angle. The operator can determine and remember different rotation angles through these jamming points to help achieve precise positioning during the operation.

[0047] In addition, by adopting the above-mentioned connection structure 100, when the stop point 110a is engaged with the stop slot 120a, the spherical joint rotor 110 and the joint stator 120 can be relatively fixed and held, thereby preventing the spherical joint rotor 110 from rotating unnecessarily without external force, not only improving the reliability of angle adjustment, but also avoiding failures or damages caused by accidental rotation.

[0048] The embodiment of the present application does not specifically limit the shape of the stop point 110a. Please refer to Figure 5 , in some embodiments, the stop point 110a can be configured as a convex hemispherical shape; correspondingly, the shape of the stop slot 120a is configured as a spherical socket shape that matches the aforementioned hemispherical shape.

[0049] The above-mentioned connection structure 100 adopts the design of a convex hemispherical stop point 110a and a spherical socket-shaped stop slot 120a, which can achieve more precise mechanical matching, ensure the stable engagement of the stop point 110a in the stop slot 120a, and prevent loosening and sliding. The cooperation mode of the hemispherical protrusion and the spherical socket-shaped depression can provide a more distinct sense of jamming, enabling the operator to more clearly perceive the position of the jamming point during the operation process. Moreover, the cooperation mode of the hemispherical protrusion and the spherical socket-shaped depression can also effectively reduce the wear between the contact surfaces of the two, thereby improving the durability and service life of the connection structure 100.

[0050] Please continue reading Figure 2 In some embodiments, a plurality of stop points 110 a may be horizontally distributed around a portion of the outer surface of the spherical joint rotor 110 .

[0051] In the above connection structure 100, the stop points 110a are horizontally and circumferentially distributed, so that the spherical joint rotor 110 is subjected to uniform force when rotating in the joint stator 120, reducing local stress concentration, thereby extending the service life of the connection structure 100. In addition, the horizontally circumferentially distributed method can ensure that the spherical joint rotor 110 has a consistent stop feeling when rotating in any direction, thereby improving the stability and accuracy of the angle adjustment operation, so that the operator can more easily perceive and control the rotation angle.

[0052] As an example, Figure 2 As shown, a plurality of protruding stop points 110 a cover at least 1 / 2 of the outer surface of the spherical joint rotor 110 .

[0053] Please combine Figure 2 It is understood that the plurality of stop points 110a cover at least 1 / 2 of the outer surface of the spherical joint rotor 110 means that: among the plurality of stop points 110a, the area of ​​the strip-shaped figure surrounded by the plurality of stop points 110a located at the top layer and the plurality of stop points 110a located at the bottom layer is greater than or equal to 1 / 2 of the outer surface area of ​​the spherical joint rotor 110.

[0054] In the above-mentioned connection structure 100, several stop points 110a cover 1 / 2 of the outer surface of the spherical joint rotor 110, so as to provide rotation angle limitation in a larger range, meet the requirements of multi-angle positioning, and enhance the scene compatibility of the connection structure 100. The stop points 110a covering a larger area can provide stable point positioning at more positions, ensuring the reliability and operational stability of the connection structure 100 at different angles. The design of the stop points 110a with a wider coverage range can provide a sense of stuttering at more rotation angles, allowing operators to flexibly adjust and position during operation, further improving the user experience of the connection structure 100.

[0055] In some embodiments, a wear-resistant pad 120b may be provided on the stop slot 120a. When the stop slot 120a is engaged with the stop point 110a, the wear-resistant pad 120b may be located between the stop slot 120a and the stop point 110a and contact the stop point 110a.

[0056] The connection structure 100, through the provision of the wear-resistant liner 120b, effectively reduces the direct contact wear between the stop point 110a and the stop slot 120a, prolongs the service life of both, and further improves the durability of the connection structure 100. The wear-resistant liner 120b can absorb and disperse part of the mechanical stress between the stop point 110a and the stop slot 120a, protect the stop slot 120a and the stop point 110a from excessive mechanical stress, thereby preventing the connection structure 100 from being damaged.

[0057] According to some embodiments, the present application also provides another connection structure. The connection structure may specifically include a spherical joint rotor and a joint stator; wherein at least part of the outer surface of the spherical joint rotor is provided with a plurality of recessed stop slots; the internal shape of the joint stator is configured as a spherical inner surface, and the spherical inner surface matches the shape of the spherical joint rotor, so that the spherical joint rotor can rotate universally in the joint stator.

[0058] Specifically, a stop point that matches the stop slot may be provided on the spherical inner surface, and the stop point is used to engage with the stop slot so that the spherical joint rotor and the joint stator are relatively fixed.

[0059] The above-mentioned connection structure is provided with a plurality of recessed stop grooves on the outer surface of the spherical joint rotor, and corresponding stop points are provided on the spherical inner surface of the joint stator. In this way, the spherical joint rotor can have an obvious stop position after rotating to a certain angle, so that the operator can judge whether the current spherical joint rotor has reached a specific rotation angle by feeling the stop, so that the operator can perceive the current position of the spherical joint rotor more intuitively, thereby solving the problem of being unable to determine the rotation angle in related technologies.

[0060] When the stop slot of the above-mentioned connecting structure is engaged with the stop point, the spherical joint rotor and the joint stator can also be relatively fixed, thereby preventing the spherical joint rotor from unnecessary rotation without external force, which not only improves the reliability of angle adjustment, but also avoids failure or damage caused by accidental rotation.

[0061] The embodiment of the present application does not specifically limit the shape of the stop slot. In some embodiments, the stop slot can be configured as a concave ball socket; correspondingly, the shape of the stop point is configured as a hemispherical shape that matches the aforementioned ball socket.

[0062] In some embodiments, a plurality of stop grooves are horizontally distributed around a portion of the outer surface of the spherical joint rotor.

[0063] As an example, a plurality of recessed stop grooves cover at least 1 / 2 of the outer surface of the spherical joint rotor.

[0064] It should be noted that the fact that several recessed stop slots cover at least 1 / 2 of the outer surface of the spherical joint rotor means that: among several stop slots, the area of the strip-shaped figure formed by the multiple stop slots at the top layer and the multiple stop slots at the bottom layer is greater than or equal to 1 / 2 of the outer surface area of the spherical joint rotor.

[0065] It can be understood that the technical effects achievable by the connection structure provided in the above embodiments can be understood by referring to the relevant content of the foregoing connection structure 100, and will not be elaborated herein. It can be understood that through the design of the stop points and stop slots in the embodiments of the present application, the angle adjustment operation of the spherical joint rotor is simple and easy to implement, and the operator can make the spherical joint rotor dock at the specified position during actual operation. Therefore, the connection structure provided in the embodiments of the present application is particularly suitable for application scenarios that require frequent angle adjustment, improving the operation efficiency and user experience of the connection structure.

[0066] According to some embodiments, on the other hand, the present application also provides an electromechanical device. The electromechanical device may include the connection structure provided in any of the foregoing embodiments, such as Figure 1 the connection structure 100 shown. Therefore, the technical effects achievable by the foregoing connection structure can also be achieved by this electromechanical device, and will not be elaborated herein.

[0067] That is to say, the connection structure provided in any of the foregoing embodiments can be applied to many types of electromechanical devices, such as inverters; in addition, it may also include, for example, motors, electric power steering gears, electric compressors, electric air pumps, and the like.

[0068] It should be noted that the electromechanical device may also include other component structures such as a housing, a circuit board, and cables. Other possible component structures are not the focus of the present application, and other component structures can also be understood by referring to related technologies, and will not be further elaborated herein.

[0069] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features of the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0070] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
