[0056] With the development of transportation technology, manned aircraft are becoming more and more popular. Manned aircraft, electric vehicles and other transportation tools usually use motor equipment such as drive motors to provide power. During the operation of the drive motor, it is usually necessary to use motor sensors such as temperature sensors and eddy current sensors to detect parameters such as temperature and eddy current.

[0057] The related technology usually uses binding ropes to bind the motor sensor, and further fixes the motor sensor through insulating paint; among them, the method of using binding ropes requires high skills of workers, and the assembly of the motor sensor is relatively cumbersome.

[0060] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the motor device includes a drive motor 300 and a sensor assembly as described below. Figure 1 ,in Figure 1Only part of the structure of the drive motor 300 is shown; the drive motor 300 includes a rotor 310, a stator 320 and a winding 330, the stator 320 includes a connected yoke body 321 and a plurality of spaced teeth 322, the yoke body 321 and the tooth body 322 can be configured to be integrally formed; of course, the yoke body 321 and the tooth body 322 can also be connected after being separately formed by means of a slot structure or the like.

[0061] In addition, tooth grooves 323 are formed between adjacent tooth bodies 322; the winding 330 includes a straight section 331 and a bent section 332 connected to each other, the straight section 331 is accommodated in the tooth groove 323, and the bent section 332 is arranged opposite to the tooth body 322 to form an accommodating recess 301. Further, the accommodating recess 301 in this embodiment includes a first opening and a second opening arranged opposite to each other, for example, the first opening is arranged at Figure 2 The second opening is located at the left end of the Y axis direction. Figure 2 In this embodiment, the straight section 331, the bent section 332 and the tooth body 322 constitute the outer periphery of the first opening and the second opening, which can be understood as the straight section 331, the bent section 332 and the tooth body 322 forming the first opening and the second opening.

[0062] Of course, the driving motor 300 may also form the above-mentioned accommodating recess 301 through structures such as the inner surface of the motor housing, and the accommodating recess may also have only one opening, which is not limited in this embodiment.

[0063] The winding 330 may include a plurality of winding wires, and the winding wires may be round wires or flat wires; it is understood that the straight section 331 and the bent section 332 may be understood as a part of the winding wire. When the winding wire is a flat wire, the cross-sections of the winding wire, the straight section 331 and the bent section 332 may be set to a rectangular or rounded rectangular shape. In addition, the winding 330 may further include an insulating film 333, which is arranged between the straight section 331 and the tooth body 322, so as to improve the insulation performance between the winding wire and the tooth body 322.

[0064] Among them, the sensing component of the motor equipment includes a motor sensor 200 and a fixing device 100 described below. It can be understood that the motor sensor 200 can be stored, transported or assembled as a whole by fixing it on the fixing device 100. In addition, the fixing device 100 is used to fix the motor sensor 200 to the drive motor 300. The motor sensor 200 may include a temperature sensor, an eddy current sensor, etc. The following mainly introduces the structure of the fixing device 100, etc., taking the temperature sensor as the motor sensor 200. In the absence of obvious conflicts, the structure described below can also be applied to other motor sensors except the temperature sensor.

[0065] In some embodiments, reference Figure 3 and Figure 4 The motor sensor 200 includes a sensor body 210 and a wire 220 connected to each other, wherein the sensor body 210 can be understood as a structure that converts temperature signals and other signals into electrical signals, such as a thermistor, etc. The wire 220 is connected to the sensor body 210, so that the converted electrical signal can be transmitted. In some embodiments, the cross-section of the sensor body 210 can be set to a rectangular or rounded rectangular shape, so as to increase the contact area with the winding wire in the form of a flat wire, thereby further improving the installation stability.

[0066] The fixing device 100 includes a mounting seat 110, and the mounting seat 110 is used to be clamped in the receiving recess 301 of the drive motor 300. It can be understood that the mounting seat 110 can be clamped in the receiving recess 301, for example, by interference fit, snap connection, threaded connection, etc. The mounting seat 110 has a mounting slot 111 and a harness slot 113, and the wall surface of the mounting slot 111 includes an abutment surface section 112; the mounting slot 111 is used to accommodate at least part of the sensor body 210, including accommodating a part of the sensor body 210 and accommodating the entire sensor body 210. The abutment surface section 112 is used to abut against one end of the sensor body 210 facing the wire 220, for example, abutting Figure 2 , Figure 3 In some embodiments, the mounting slot 111 may be rectangular as a whole, and the abutting surface section 112 may be understood as a side surface of the mounting slot 111, for example Figure 3 , Figure 4 of course, the abutment surface segment 112 may be a part of the wall of the mounting slot 111.

[0067] The harness groove 113 is connected to the abutment surface section 112, and the cross-sectional area of ​​one end of the harness groove 113 facing the abutment surface section 112 is smaller than the area of ​​the abutment surface section 112, so that the harness groove 113 and the abutment surface section 112 form a step structure, so that the above-mentioned wire 220 can continue to be laid outward through the harness groove 113, but the sensor body 210 stops at the abutment surface section 112 and at the formed step structure due to the abutment of the abutment surface section 112.

[0068] Reference Figure 3 and Figure 4 , at least part of the extension direction of the harness groove 113 intersects with the normal direction of the abutment surface segment 112; for example, the left part of the harness groove 113 in the figure extends along the Y-axis direction, and the abutment surface segment 112 is parallel to the YZ plane so that its normal direction is set along the X-axis direction, which can be understood as Figure 3 and Figure 4The extension direction of the middle harness groove 113 is perpendicular to the normal direction of the abutting surface segment 112. Of course, the extension direction of the harness groove 113 can also be set to form an angle greater than 0 degrees and less than 90 degrees with the normal direction of the abutting surface segment 112, and this embodiment is not limited to this.

[0069] The harness groove 113 is used to accommodate the wire 220, so that the wire 220 can be bent through the portion of the harness groove 113 where the extending direction intersects with the normal direction of the abutting surface segment 112, so that the bent portion of the wire 220 can be limited on one side of the sensor body 210, for example, Figure 3 The left side of the sensing body 210 is limited. It can be understood that the extension direction of the harness groove 113 can be parallel to the axial direction of the rotor 310, and the extension direction of the harness groove 113 can also be parallel to the cross section of the rotor 310 or be inclined to the cross section of the rotor 310. In addition, the harness groove 113 can also include more than two slot segments arranged at intervals, and the extension direction of the slot segment intersects with the normal direction of the abutting surface segment 112. It can be understood that the harness groove 113 can include at least two bending areas, so that the corresponding wire 220 forms at least two bent conductor segments.

[0070] In this embodiment, the fixing device 100 can fix the motor sensor 200 to the mounting seat 110 by abutting the sensor body 210 against the abutment surface segment 112 and accommodating the wire 220 in the harness groove 113 intersecting the normal direction of the abutment surface segment 112; the fixing device 100 can also be clamped in the accommodating recess 301 of the drive motor 300 through the mounting seat 110, thereby achieving fixation of the motor sensor 200 and the drive motor 300, which is beneficial to improving the assembly convenience of the motor sensor 200.

[0071] In some embodiments, reference Figure 3 and Figure 4 , the side wall surface of the harness groove 113 extends to the surface of the mounting seat 110, so that the harness groove 113 forms a notch 114 in the circumferential direction, which can be understood as the harness groove 113 is a non-enclosed groove structure. The fixing device 100 also includes a harness cover 120, which is clamped to the mounting seat 110 and at least partially covers the notch 114. Specifically, the clamping can be achieved by a buckle structure, a slot structure, etc.; wherein the harness cover 120 is used to abut the side wall surface of the wire 220, thereby reducing the risk of the wire 220 being loosened due to the vibration of the drive motor 300 and other reasons, and improving the connection stability of the motor sensor 200 on the drive motor 300.

[0072] In some embodiments, reference Figure 4The mounting seat 110 includes an embedded portion 115 and an extended portion 116. The extending direction of the embedded portion 115 and the extending direction of the extended portion 116 form an angle, which can be understood as the embedded portion 115 and the extended portion 116 are not parallel. The embedded portion 115 is used to be embedded in the receiving recess 301 of the drive motor 300, and the extended portion 116 is used to be arranged outside the receiving recess 301; it can be understood that the embedded portion 115 is the portion of the mounting seat 110 embedded in the receiving recess 301, and the extended portion 116 is the portion located outside the receiving recess 301.

[0073] The mounting slot 111 is disposed on the embedded portion 115 , and the harness slot 113 is at least partially disposed on the extended portion 116 , so that the sensor body 210 can extend into the accommodating recess 301 along with the embedded portion 115 , and at least part of the wire 220 can be located outside the accommodating recess 301 .

[0074] The harness cover 120 is provided with at least one cover arm 121, and the at least one cover arm 121 is used to be arranged between the side wall surface of the protruding portion 116 and the surface of the peripheral entity of the receiving recess 301, for example, referring to Figure 2 At least one cover arm 121 is arranged between the protruding portion 116 and the straight section 331 or the bent section 332 of the above-mentioned winding 330, so that the cover arm 121 can be limited between the protruding portion 116 and the peripheral entity of the accommodating recess 301, reducing the risk of accidental loosening of the wiring harness cover 120.

[0075] In some embodiments, reference Figure 3 and Figure 4 , one of the sidewalls of the cover arm 121 and the overhanging portion 116 is provided with a first buckle body 117, and the other of the sidewalls of the cover arm 121 and the overhanging portion 116 is provided with a first buckle groove 122, and the first buckle body 117 is buckled with the first buckle groove 122. The cover arm 121 may be provided with the first buckle body 117 and the overhanging portion 116 may be provided with the first buckle groove 122; or the overhanging portion 116 may be provided with the first buckle body 117 and the cover arm 121 may be provided with the first buckle groove 122, and this embodiment is not limited thereto.

[0076] In this embodiment, the cover arm 121 and the protruding portion 116 can be quickly buckled together through the first buckle body 117 and the first buckle groove 122, reducing assembly interference caused by the peripheral entity between the protruding portion 116 and the accommodating recess 301, thereby improving assembly efficiency.

[0077] In some embodiments, reference Figure 3 and Figure 4The side wall surface of the protruding portion 116 is provided with an engaging groove 118, and the engaging groove 118 is used to face the wall surface of the accommodating recess 301 and is provided with a first buckle body 117 or a first buckle groove 122. The cover arm 121 is at least partially accommodated in the engaging groove 118, thereby reducing the protrusion of the cover arm 121 relative to the protruding portion 116, further reducing the risk of the cover arm 121 being interfered with by the peripheral entity of the accommodating recess 301, and further improving the assembly efficiency.

[0078] In some embodiments, reference Figure 4 The mounting seat 110 includes two inwardly extending sections 130 arranged at intervals, and the inwardly extending sections 130 are used to extend in a direction from the first opening to the second opening, for example, along the X direction in the figure; it can be understood that the above-mentioned embedded part 115 can be composed of various inwardly extending sections 130.

[0079] Reference Figure 2 The two inner extension sections 130 are used to extend from the first opening into the receiving recess 301, and at least one inner extension section 130 is used to extend from the receiving recess 301 to the second opening, for example, Figure 2 The device is inserted into the left opening of the receiving recess 301 and exits from the right opening. Figure 2 and Figure 4 , at least one end of the inner extension section 130 extending out of the second opening is provided with a limiting buckle body 131, and the limiting buckle body 131 is used to abut against the surface of the peripheral entity of the second opening, such as the surface of the straight section 331 or the bending section 332, so as to achieve the right side limit. Correspondingly, a limiting plate 140 is provided on the side of the mounting seat 110 away from the limiting buckle body 131, for example, the limiting plate 140 is provided on the side of the overall left side in the figure, and the limiting plate 140 is used to abut against the surface of the peripheral entity of the second opening formed by the driving motor 300, such as the surface of the straight section 331 or the bending section 332, so as to achieve the left side limit. It can be understood that the mounting seat 110 can be provided with two spaced limiting plates 140, so as to form a gap to connect the above-mentioned mounting slot 111 and the harness slot 113, thereby improving the structural compactness of the fixing device 100; in addition, the above-mentioned abutting surface section 112 can be provided on the limiting plate 140, thereby further improving the structural compactness of the fixing device 100.

[0080] In this embodiment, the mounting seat 110 can be fixed to the accommodating recess 301 having a first opening and a second opening through the limiting buckle body 131 and the limiting plate 140, thereby further improving the installation stability of the motor sensor 200 on the driving motor 300, and further improving the assembly convenience of the motor sensor 200.

[0081] In some embodiments, reference Figure 4, the height direction of the position-limiting buckle body 131 faces away from the inner extending interval 132 between two adjacent inner extending sections 130, the ratio of the height (L11 or L12) of the position-limiting buckle body 131 to the width L2 of the inner extending interval 132 is less than or equal to 0.5, and the width direction of the inner extending interval 132 is arranged along the arrangement direction of the inner extending sections 130, for example, along the Y-axis direction in the figure. Among them, the heights of the two position-limiting buckles 131 on both sides of the inner extending interval 132 can be made equal, that is, L11=L12; or, the sum of the height of the position-limiting buckle body 131 on one side of the inner extending interval 132 and the height of the position-limiting buckle body 131 on the other side can be further made less than or equal to the width L2 of the inner extending interval 132, that is, L11+L12≤L2.

[0082] In this embodiment, the ratio of the height (L11 or L12) of the limiting buckle body 131 to the width L2 of the inwardly extending gap 132 is less than or equal to 0.5. The limiting buckle body 131 can extend inwardly into the gap 132 to reduce friction during movement during the process of penetrating into the accommodating recess 301, and can stably hook after passing through the accommodating recess 301.

[0083] In some embodiments, reference Figure 2 and Figure 3 , the first device side 211 of the sensor body 210 is used to abut against the entity part forming the accommodating recess 301, for example, the upper side of the sensor body 210 abuts against the straight section 331 or the bent section 332 of the winding 330; the second device side 212 of the sensor body 210 is used to abut against the wall surface of the mounting slot 111, for example, the upper side of the sensor body 210 abuts against the wall surface of the mounting slot 111; the first device side 211 and the second device side 212 are arranged opposite to each other, for example, they are respectively arranged as the upper side and the lower side of the sensor body 210; refer to Figure 5 , Figure 6 and Figure 7 The fixing device 100 further includes an elastic plate 150, which can be understood as an elastic plate member; the elastic plate 150 is used to abut against the second device side 212, for example Figure 7 The elastic plate 150 is used to make the first device side 211 abut against the solid part forming the accommodating recess 301. It can be understood that the elastic plate 150 is used to provide elastic force to the sensor body 210 so that the sensor body 210 remains abutted against the solid part forming the accommodating recess 301 (for example, the upper side of the sensor body 210 abuts against the straight section 331 or the bent section 332 of the winding 330). Figure 7 The following is a comparison diagram showing the use of the elastic plate 150 of the fixing device 100 in this embodiment. Figure 7As shown in the upper side diagram, when the sensor body 210 is not installed, the right end of the elastic plate 150 is tilted higher; in some embodiments, the right end of the elastic plate 150 can form an interference amount with the sensor body 210 that is greater than or equal to 1.2 mm and less than or equal to 1.5 mm. It can be understood that installing the sensor body 210 will cause the right end of the elastic plate 150 to drop by 1.2 to 1.5 mm, so that the interference amount can be absorbed through the elastic deformation of the elastic plate 150, so that the elastic force acting on the sensor body 210 is more moderate.

[0084] Reference Figure 7 As shown in the lower side diagram, when the sensor body 210 is installed, the right end of the elastic plate 150 is squeezed by the sensor body 210, thereby forming elastic deformation and providing elastic force, thereby improving the connection stability of the sensor body 210.

[0085] In some embodiments, the mounting base 110 is provided with an avoidance groove 133, and at least a portion of the elastic plate 150 is accommodated in the avoidance groove 133. The elastic plate 150 and the wall of the avoidance groove 133 are separately arranged and fixedly connected, so that after the mounting base 110 and the sensor body 210 are inserted from the first opening of the accommodating recess 301, the elastic plate 150 is inserted from the second opening of the accommodating recess 301, thereby reducing the risk of hard extrusion between the mounting base 110 or the elastic plate 150 and the accommodating recess 301, and further improving the convenience of installation.

[0086] In some embodiments, reference Figure 7 The first plate end 151 of the elastic plate 150 is used to face the first opening, for example, Figure 7 The first plate end 151 is fixedly connected to the avoidance groove 133, including a detachable fixed connection and a non-detachable fixed connection. The second plate end 152 of the elastic plate 150 is used to face the second opening, for example, toward Figure 7 the second plate end 152 is bent in a direction toward the second device side 212, for example, bent toward the upper side, and the second plate end 152 is used to abut the second device side 212, so as to provide a greater elastic force through the bend, which is beneficial to further improve the connection stability of the sensor body 210.

[0087] In some embodiments, the thickness of the elastic plate 150 on the side facing the second plate end 152 may be set to be greater than or equal to 1.2 mm and less than or equal to 1.4 mm, so as to avoid excessive rigidity of the elastic plate 150 .

[0088] In some embodiments, reference Figure 6 and Figure 7The first plate end 151 is fixedly connected to the wall of the avoidance groove 133 in a direction parallel to the second device side 212, for example, in the left-right direction in the figure; the first plate end 151 is movably connected to the avoidance groove 133 in a direction perpendicular to the second device side 212, for example, in Figure 6 The direction perpendicular to the drawing plane, Figure 7 the first plate end 151 is used to be spaced apart from the second device side 212, and the first plate end 151 is used to abut the second plate end 152 with the second device side 212 and move toward the second device side 212.

[0089] Continue to refer to Figure 7 In this embodiment, the right end of the elastic plate 150 is squeezed by the sensor body 210, so that the second plate end 152 drops and the first plate end 151 rises, which is beneficial for the first plate end 151 and the second plate end 152 to abut against the sensor body 210 at the same time, thereby helping to further improve the connection stability of the sensor body 210.

[0090] In some embodiments, reference Figure 8 and Fig. 9 The first seat body side of the mounting seat 110 is used to abut against the side wall surface of the accommodating recess 301, and the second seat body side of the mounting seat 110 is provided with the above-mentioned card slot 111, and the first seat body side is arranged opposite to the second seat body side; for example, Fig. 9 The upper side of the middle mounting seat 110 is provided with a slot 111 to accommodate the sensor body 210. Fig. 9 The lower side of the middle mounting seat 110 abuts against the side wall surface of the accommodating recess 301. In addition, the thickness direction of the first plate end 151 is arranged along the direction from the first seat body side to the second seat body side, for example, along Fig. 9 the thickness of the first plate end 151 is smaller than the distance from the mounting slot 111 for abutting the side of the sensor body 210 to the side of the first seat body, thereby facilitating the first plate segment 151 to swing with the second plate end 152.

[0091] In some embodiments, reference Fig. 9 The end of the mounting slot 111 and the end of the inward extension section 130 facing the second opening are spaced apart. For example, the end of the mounting slot 111 and the right end of the inward extension section 130 are spaced apart. It can be understood that one end of the sensor body 210 is accommodated in the mounting slot 111 and the other end is suspended relative to the mounting slot 111. The elastic plate 150 is provided with a support slot 153 at one end facing the second opening, and the end of the sensor body 210 away from the mounting slot 111 abuts against the wall of the support slot 153; for example Fig. 9A support groove 153 is provided at the right end of the middle elastic plate 150 , and the right end of the sensor body 210 abuts against the wall of the support groove 153 , so that the elastic plate 150 can provide elastic force by changing its shape and improve the support stability of the sensor body 210 through the support groove 153 .

[0092] In some embodiments, reference Figure 6 or Fig.10 A second buckle body 134 is provided on one of the outer wall surface of the elastic plate 150 and the wall surface of the avoidance groove 133, and a second buckle groove 154 is provided on the other of the outer wall surface of the elastic plate 150 and the wall surface of the avoidance groove 133. The second buckle body 134 is buckled and connected with the second buckle groove 154, thereby improving the installation convenience of the elastic plate 150, and also realizing that the first plate end 151 and the wall surface of the avoidance groove 133 are fixedly connected in a direction parallel to the second device side 212, and the first plate end 151 and the avoidance groove 133 are movably connected in a direction perpendicular to the second device side 212.

[0093] For example, the outer wall surface of the elastic plate 150 may be provided with a second buckle body 134, and the wall surface of the avoidance groove 133 may be provided with a second buckle groove 154; or the wall surface of the avoidance groove 133 may be provided with a second buckle body 134, and the outer wall surface of the elastic plate 150 may be provided with a second buckle groove 154, and this embodiment is not limited to this.

[0094] In some embodiments, reference Figure 6 The inward extension interval 132 between two adjacent inward extension sections 130 forms the above-mentioned avoidance groove 133, which can be understood as the two inward extension sections 130 are respectively cantilever structures, thereby improving the elasticity of the inward extension sections 130; the second buckle body 134 is arranged on the side of the inward extension section 130 facing the avoidance groove 133, thereby improving the structural strength of the inward extension section 130.

[0095] In some embodiments, reference Figure 4 or Figure 6 The second buckle body 134 is used to form a first angle with the wall of the inner extension section 130 facing the second opening, and the first angle is greater than 90 degrees, so as to facilitate the installation of the elastic plate 150; the second buckle body 134 is used to form a second angle with the wall of the inner extension section 130 facing away from the second opening, and the second angle is less than or equal to 90 degrees, so as to facilitate the fixing of the installed elastic plate 150.

[0096] In some embodiments, reference Figure 6 , Fig.10 and Fig.11 The side of the inner extension section 130 facing away from the avoidance groove 133 is used to be spaced apart from the side wall surface of the accommodating recess 301, for example, spaced apart from the surface of the winding 330, thereby forming Fig.10 Gap G in the reference Figure 6During the installation process of the elastic plate 150, the inner extension section 130 will bend outward due to the compression of the second buckle body 134. At this time, the above-mentioned gap G can not only accommodate the deformation of the inner extension section 130 to bend outward and improve the installation convenience of the elastic plate 150; it can also prevent the inner extension section 130 from excessively bending, thereby reducing the risk of damage to the inner extension section 130.

[0097] In some embodiments, the distance between the side of the inner extension section 130 facing away from the avoidance groove 133 and the side wall surface of the accommodating recess 301 can be set to be greater than 0 and less than or equal to 0.1 mm, thereby improving installation convenience and reducing the risk of looseness.

[0098] In some embodiments, reference Figure 6 and Fig.10 The elastic plate 150 further includes two elastic arms 155 spaced apart from each other. The elastic arms 155 are used to face the first opening, for example, toward the left side in the figure; the elastic arms 155 are used to extend from the second opening to the first opening, for example, along Figure 6 The second buckle body 134 or the second buckle groove 154 is arranged on the elastic arm 155 and is extended to the left and right sides of the elastic arm 155.

[0099] In this embodiment, the two elastic arms 155 arranged at intervals can be relatively retracted, thereby reducing the squeezing force on the extending section 130 during the installation of the elastic plate 150, which not only further improves the installation convenience of the elastic plate 150, but also can further prevent the extending section 130 from excessive bending and further reduce the risk of damage to the extending section 130.

[0100] In some embodiments, the fixing device 100 may be made of plastic, for example, the mounting seat 110, the wiring harness cover plate (120), the inner extension section 130, the limiting plate 140, and the elastic plate 150 may be respectively made of plastic.

[0105] Step 4: insert the elastic plate 150 from the second opening of the accommodating recess 301 and fix the elastic plate 150 to the wall surface of the avoiding groove 133 .

[0106] Among them, the above step three is performed before the above step four, which can be understood as first inserting the motor sensor 200 and the mounting base 110 into the accommodating recess 301, and then inserting the above elastic plate 150, thereby reducing the risk of assembly interference formed by the mounting base 110 or the elastic plate 150, which is conducive to improving installation efficiency.
