[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] First of all, it should be noted that some directional words involved in the following description to clearly illustrate the technical solution of the utility model are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The utility model provides an eddy current sensor stator, comprising a housing 2, a circuit board 4, a wiring harness 5 and a transfer terminal 1, wherein one end of the transfer terminal 1 is connected to the circuit board 4 in the housing 2, and the other end is welded to the wiring harness 5.

[0046] It should be noted that the stator of the eddy current sensor of the present invention, see Figure 1 and Fig. 9 As shown, the adapter terminal 1 is embedded in the injection mold and is integrally formed with the shell 2 through a molding process. A circuit board 4 is installed in the shell 2. One end of the adapter terminal 1 is welded to the circuit board 4, and the other end is connected to the wiring harness 5 by welding. The sealing performance is good, which can prevent foreign matter from entering the circuit board 4 inside the eddy current sensor, thereby extending the service life of the circuit board 4 and ensuring its working stability.

[0047] In some embodiments of the present invention, Figure 1 and Figure 8 As shown, the adapter terminal 1 is L-shaped, and one end of the adapter terminal 1 is inserted into the through hole in the circuit board 4 and welded to the circuit board 4. It should be noted that the adapter terminal 1 is L-shaped, with a bent portion, and one end of the bent portion is vertically inserted into the through hole in the circuit board 4, and the adapter terminal 1 and the circuit board 4 are fixed by welding, thereby realizing the transmission of electrical signals.

[0048] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the housing 2 includes a disk body 21, and a plurality of equally spaced disk body mounting holes 211 are arranged on the circumference of the disk body 21. It should be noted that a circuit board mounting groove is formed in the disk body 21 for mounting the circuit board 4. The top of the circuit board mounting groove is higher than the highest electronic component on the circuit board 4 and the height difference with the highest electronic component is not less than 1 mm. The flatness of the bottom surface of the circuit board mounting groove is within 0.1 mm, so as to ensure the relative position relationship between the circuit board 4 and the rotor blade 3. The distances between adjacent mounting holes 211 are equal, so as to ensure that the fasteners can uniformly apply preload along the circumference of the housing 2 during the process of mounting the housing 2 to the motor end cover.

[0049] In some embodiments of the present invention, Figure 2As shown, a protective sleeve 6 is provided in the mounting hole 211 of the disk body, and the hardness of the protective sleeve 6 is greater than the hardness of the disk body 21. It should be noted that since the material of the shell 2 is generally plastic, when bolts are directly used for fastening, it is easy to cause the mounting hole 211 to deform. Therefore, the protective sleeve 6 installed in the mounting hole 211 can play a protective role. The hardness of the protective sleeve 6 is greater than the hardness of the disk body 21, so as to ensure that the mounting hole 211 does not deform during the application of the pre-tightening force. At least one axial end of the protective sleeve 6 protrudes from the mounting hole 211 of the disk body, and the specific size can be designed and adjusted according to the axial installation requirements of the stator of the eddy current sensor.

[0050] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the back of the housing 2 is provided with a plurality of evenly distributed weight-reducing grooves 213 along the outer circumference. It should be noted that the provision of the weight-reducing grooves 213 can reduce the deadweight of the disc portion 21 and reduce the production cost. In addition, the housing 2 is also provided with at least one disc protrusion 212, which extends along the axial direction of the housing 2. The housing 2 can be quickly installed on the motor end cover by aligning the disc protrusion 212 with the positioning hole on the motor end cover.

[0051] In some embodiments of the present invention, Figure 4 As shown, the housing 2 also includes an extension portion 22, and the extension portion 22 includes a plurality of extension blocks 221 arranged in parallel, and a mounting groove is formed between two adjacent extension blocks 221, and the wiring harness 5 and the adapter terminal 1 are welded in the mounting groove. It should be noted that the extension portion 22 and the disk body portion 21 are integrally formed during injection molding, and are arranged along the edge of the disk body portion 21, and the extension block 221 can be strip-shaped, and a mounting groove is formed between adjacent extension blocks 221, and the wiring harness 5 and the adapter terminal 1 are installed in the mounting groove. When the wiring harness 5 and the adapter terminal 1 need to be connected, the two can be connected by welding.

[0052] In some embodiments of the present invention, Figure 7As shown, it also includes a clamping member 7, on which a plurality of clamping teeth 71 are arranged at intervals, and the clamping teeth 71 are arranged in the installation groove to clamp the wire harness 5. It should be noted that the edges of the clamping teeth 71 need to be chamfered to prevent the wire harness 5 from causing significant wear to the wire harness sheath when it is vibrated, and a wire harness installation groove is formed between adjacent clamping teeth 71, and the wire harness 5 is installed inside it. It should be emphasized that a clamping protrusion 2212 is provided on the extension blocks 221 on both sides, and a clamping groove 72 is also provided on the outer side of the clamping member 7, and the clamping protrusion 2212 and the clamping groove 72 are connected by clamping. It should also be emphasized that a guide groove 2211 is provided on the extension blocks 221 on both sides, and a guide strip 73 adapted to the guide groove 2211 is provided on both sides of the clamping member 7, and the guide strip 73 is arranged in the guide groove 2211, and the guide strip 73 can be quickly aligned with the guide groove 2211, so that the clamping member 7 can be quickly installed.

[0053] In some embodiments of the utility model, the bottom of the installation groove is provided with a welding hole 2213 that passes through the bottom of the groove, and the adapter terminal 1 is provided with a positioning hole 9, and the positioning hole 9 and the welding hole 2213 are staggered. It should be noted that the arrangement of the welding holes 2213 corresponds to the adapter terminal 1 one by one, and the setting of the positioning holes 9 facilitates the injection molding of the adapter terminal 1 and the housing 2 together. Before injection molding, one end of the adapter terminal 1 is fixed by setting the positioning holes 9, and the other end of the adapter terminal 1 can be fixed in the same or different positioning methods; the setting of the welding holes 2213 can make the wiring harness 5 and the adapter terminal 1 accurately welded, and the positioning holes 9 and the welding holes 2213 are staggered, which can improve the welding quality.

[0054] In some embodiments of the present invention, the circuit board 4 is filled with a packaging layer 8. It should be noted that the material of the packaging layer 8 can be a curing glue, and the packaging layer 8 can press the circuit board 4 tightly against the mounting groove of the housing 2 on the one hand, and prevent some external foreign matter from entering the circuit board mounting groove and affecting the service life of the circuit board 4 on the other hand.

[0055] The second aspect of the utility model provides an eddy current sensor, including the eddy current sensor stator and rotor blades 3 of the above technical solution. It should be noted that the magnetic field on the circuit board 4 changes by rotating the rotor blades 3, and the rotation angle of the motor shaft can be measured. During operation, when the motor shaft rotates, the rotor blades 3 can be driven to cut the magnetic field generated by the circuit board 4, causing the magnetic field to change. After the circuit board 4 detects the change in the magnetic field, it converts the received magnetic field signal into an electrical signal and transmits it to the display measurement device through the adapter terminal 1 and the wiring harness 5, and the rotation angle of the motor shaft is reflected by the specific waveform characteristics of the electrical signal.

[0056] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the inner circumference of the rotor blade 3 is provided with a block protrusion 31, and the outer circumference of the rotor blade 3 is provided with a plurality of leaf bends 32, and the outer edge of the leaf bend 32 exceeds the outer contour of the circuit board 4. It should be noted that the block protrusion 31 cooperates with the positioning groove on the motor shaft, and can drive the rotor blade 3 to rotate under the drive of the motor shaft. The block protrusion 31 can improve the assembly reliability of the rotor blade 3 of the eddy current sensor and the stability of signal transmission. The rotor blades of the existing eddy current sensor are mostly made of plastic material, and the metal that cuts the magnetic field is the copper-coated area inside the rotor blade. A protective cover needs to be installed on the outside of the rotor blade to prevent damage and splashing due to insufficient strength of the rotor blade, which indirectly increases the production cost of the rotor blade. The rotor blade 3 of the utility model is made of metal material, the process is relatively mature, the assembly is simple, and the cost is relatively low. It should be emphasized that the outer edge of the leaf bend 32 exceeds the outer contour of the circuit board 4, that is, the extension length of the leaf bend 32 exceeds and covers the transmitting coil and the receiving coil on the circuit board 4, and the number of leaf bends 32 is consistent with the number of coil pole pairs on the circuit board 4. The number of coil pole pairs can divide a period of sine function or cosine function into several parts corresponding to the number of poles, so that when the rotor blade 3 rotates, the rotation speed and position information of the rotor blade 3 can be obtained according to the periodic change of the signal, and then the rotation angle of the motor shaft can be obtained. The flatness of the front and back surfaces of the rotor blade 3 is less than 0.1mm, so as to meet the relative position relationship between the disc body 21 and the rotor blade 3, and ensure that the output signal can accurately reflect the rotation angle of the motor shaft.

[0057] As a relatively preferred embodiment of the eddy current sensor of the utility model, it includes a housing 2, a circuit board 4, a wiring harness 5, an adapter terminal 1 and a rotor blade 3. The adapter terminal 1 is L-shaped, one end of the adapter terminal 1 is inserted into the through hole in the circuit board 4 and welded to the circuit board 4, and the other end is welded to the wiring harness 5. The housing 2 includes a disk body 21, and a plurality of equidistantly distributed disk body mounting holes 211 are arranged on the circumferential side of the disk body 21. A protective sleeve 6 is arranged in the disk body mounting hole 211, and the hardness of the protective sleeve 6 is greater than that of the disk The hardness of the body 21, at least one axial end of the protective sleeve 6 protrudes from the disc mounting hole 211, the back of the shell 2 is provided with a plurality of uniformly distributed weight reduction grooves 213 along the outer peripheral side, the shell 2 is also provided with a disc protrusion 212, the disc protrusion 212 extends along the axial direction of the shell 2, the shell 2 also includes an extension 22, the extension 22 includes a plurality of parallelly arranged extension blocks 221, a mounting groove is formed between two adjacent extension blocks 221, the bottom of the mounting groove is provided with a welding hole 2213 that penetrates the bottom of the groove, the transfer terminal 1 is provided with a positioning hole 9, the positioning hole 9 and the welding hole 2213 are staggered, the wiring harness 5 and the transfer terminal 1 are welded in the installation groove, and also includes a clamping member 7, the clamping member 7 is provided with a plurality of clamping teeth 71 at intervals, the clamping teeth 71 are arranged in the installation groove to clamp the wiring harness 5, and the extension blocks 221 located on both sides are provided with clamping protrusions 2212, and the outer side of the clamping member 7 is also provided with a clamping groove 72 adapted to the clamping protrusion 2212, and the clamping protrusion 2212 is clamped with the clamping groove 72, and the extension blocks 221 located on both sides are provided with A guide groove 2211, guide strips 73 adapted to the guide groove 2211 are arranged on both sides of the clamping piece 7, the guide strips 73 are arranged in the guide groove 2211, the circuit board 4 is filled with a packaging layer 8, a block protrusion 31 is arranged on the inner peripheral side of the rotor blade 3, and a plurality of blade bends 32 are arranged on the outer peripheral side of the rotor blade 3. The outer edge of the blade bend 32 exceeds the outer contour of the circuit board 4, and the flatness of the front and back surfaces of the rotor blade 3 is less than 0.1mm, so as to satisfy the relative position relationship between the disk body 21 and the rotor blade 3.

[0058] The working principle is: when the transmitting coil of the circuit board 4 is energized, a magnetic field is generated, and the rotating rotor blades 3 cut the magnetic field, causing the magnetic field to change. After the receiving coil on the circuit board 4 detects the change in the magnetic field, the magnetic field signal is converted into an electrical signal and transmitted to the measurement and display system through the adapter terminal 1 and the wiring harness 5. The periodic change of the signal generated according to the number of coil pole pairs on the circuit board 4 can be used to obtain the rotation speed and position information of the rotor blades 3, and then the rotation angle of the motor shaft can be obtained.
