Description

Technical Field

[0001] The present invention relates to the technical field of circuit detection equipment, and in particular to a current detection component and a carrier. Background Art

[0002] With the continuous development of new energy technology, the technical content of related new energy products is getting higher and higher. Taking electric vehicles as an example, the motor controller of electric vehicles needs to sample the current, and the demand for current sensors is extremely high.

[0003] For electric vehicles using three-phase motors, current monitoring is required for each phase of the circuit. By connecting the conductive bus in series to the circuit to be tested, based on the principle of electromagnetic induction, when current flows through the conductive bus, a magnetic field will be generated. The current sensor can detect the magnitude of the magnetic field and obtain the current value. However, since the three conductive buses of three-phase electricity are often arranged in parallel with each other, all three conductive buses will generate a magnetic field, which makes it easy for magnetic field crosstalk to occur between the conductive buses, making the current detection results prone to deviations. Summary of the invention

[0004] In view of this, the present invention provides a current detection component and a carrier to solve the problem that magnetic field crosstalk is likely to occur between conductive bars arranged in parallel with each other, resulting in deviation in current detection results.

[0005] In a first aspect, the present invention provides a current detection component, comprising:

[0006] At least two conductive bars, at least two conductive bars are arranged side by side and at intervals along the third direction; the conductive bars include a main body section and a detection section, the main body section extends along the first direction, the detection section is connected to the main body section and extends along the second direction; wherein the second direction is arranged non-parallel to the first direction;

[0007] The detection chip and the circuit board are installed on the circuit board, and the detection chip and the detection section are opposite and spaced apart.

[0008] Beneficial effect: The conductive bar includes a main section and a detection section, and the extension direction of the detection section and the main section is set at an angle. At this time, the magnetic field generated by the main section is not parallel to the detection plane of the Hall detection element, and even the magnetic field generated by the main section is perpendicular to the detection plane of the Hall detection element. This makes the main section of the conductive bar not cause magnetic field crosstalk to the adjacent Hall detection element, thereby ensuring the detection accuracy. For application scenarios where multiple conductive bars are set parallel to each other, current detection can be performed more accurately.

[0009] In an optional implementation, the detection chip is arranged on a side of the circuit board facing the conductive bar.

[0010] Beneficial effect: By arranging the detection chip on the side of the circuit board facing the conductive bar, the detection chip can be brought closer to the detection section of the conductive bar, thereby reducing crosstalk between different phases as much as possible while meeting the detection requirements.

[0011] In an optional embodiment, a portion of the detection segment shrinks along a third direction to form a neck portion, and in a plane perpendicular to the second direction, the cross-sectional area of ​​the neck portion is smaller than the cross-sectional area of ​​a region of the detection segment outside the neck portion; the detection chip is opposite to the neck portion and is spaced apart.

[0012] Beneficial effect: By shrinking the detection section along the third direction to form a neck portion, and making the detection chip opposite to the neck portion and arranged at a distance, when the current on the conductive row flows completely through the neck portion, the magnetic field generated by the neck portion can completely pass through the detection plane of the Hall detection element of the detection chip, thereby ensuring the accuracy of the detection.

[0013] In an optional embodiment, at least one conductive bar further includes: a turning section, the turning section is connected between the main section and the detection section, and the angle between the extending direction of the turning section and the third direction is less than 90°;

[0014] Along the third direction, the distance between the detection segments of two adjacent conductive bars is M1, and the distance between the main segments of two adjacent conductive bars is M2; the turning segment is suitable for making M1 larger than M2.

[0015] Beneficial effect: By increasing the spacing between the detection segments of adjacent conductive rows, the detection chip can be moved further away from the detection segments of adjacent conductive rows, thereby reducing the magnetic field crosstalk between the conductive rows and improving the accuracy of current detection of multiple lines at the same time.

[0016] In an optional implementation, M1 satisfies: M1>21 mm.

[0017] In an optional implementation, the detection chip includes a Hall detection element, and a detection plane of the Hall detection element is parallel to the second direction.

[0018] In an optional embodiment, there are three conductive bars, the conductive bars on both sides along the third direction are provided with turning sections, and the turning sections of the conductive bars on both sides along the third direction extend away from the conductive bar in the middle.

[0019] Beneficial effect: By increasing the spacing between the detection segments of adjacent conductive rows, the detection chip can be moved further away from the detection segments of adjacent conductive rows, thereby reducing the magnetic field crosstalk between the conductive rows and improving the accuracy of current detection of multiple lines at the same time.

[0020] In an optional implementation, the second direction is perpendicular to the first direction.

[0021] Beneficial effect: By making the second direction perpendicular to the first direction, that is, the main section and the detection section are perpendicular to each other, the magnetic field generated by the main section is perpendicular to the detection plane of the Hall detection element. When multiple conductive rows are arranged parallel to each other, the main section of the conductive row will not cause magnetic field crosstalk to the adjacent Hall detection element, thereby improving the accuracy of current detection in multiple lines at the same time.

[0022] In an optional embodiment, at least two detection chips are arranged on the circuit board, and the number of the detection chips corresponds to the number of the conductive bars;

[0023] The conductive bar is provided with at least one mounting hole.

[0024] Beneficial effect: In order to prevent the deformation of the circuit board as the temperature rises, which causes the distance parameters to change and thus causes the current accuracy to deteriorate, the conductive bus of this embodiment is provided with at least one mounting hole. By fixing the conductive bus, the deformation of the circuit board is reduced, thereby effectively ensuring the current detection accuracy.

[0025] In a second aspect, the present invention further provides a carrier, including a carrier body, and the above-mentioned current detection component disposed on the carrier body.

[0026] Because the carrier includes a current detection component, it has the same effect as the current detection component and is not described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] With the continuous development of new energy technology, the technical content of related new energy products is getting higher and higher. Taking electric vehicles as an example, the motor controller of electric vehicles needs to sample the current, and the demand for current sensors is extremely high.

[0043] Current sensors are also undergoing a transformation from the previous Hall module to C-type magnetic core current sensors, U-type magnetic core current sensors, and then to coreless current sensors. The Hall module uses the Hall effect to pass the wire of the current to be measured through the magnetic core, and uses the Hall chip to measure the change in magnetic flux at the closed part of the magnetic core to detect the size of the measured current. The traditional Hall module has the defect of poor accuracy. The U-type magnetic core current sensor, its magnetic core is proportional to the current peak value. The larger the peak current, the larger and heavier the required magnetic core volume. Current sensors with magnetic cores are easily affected by external magnetic fields or due to the irreversible characteristics of the magnet itself under special working conditions, which can easily lead to a decrease in measurement accuracy.

[0044] The coreless current sensor has the advantages of high precision and compact size. In the device using the coreless current sensor, the conductive bus is first connected in series to the circuit to be measured. Based on the principle of electromagnetic induction, when current flows through the conductive bus, a magnetic field is generated. The Hall unit integrated in the chip of the coreless current sensor is used to directly detect the magnetic field generated by the current passing through the conductive bus. Therefore, the measurement accuracy is significantly improved, and the obtained current value is also the current value of the circuit to be measured.

[0045] Although the coreless current sensor has high detection accuracy for a single line, since the three conductive bars of the three-phase electricity are often arranged in parallel with each other, the three conductive bars will generate magnetic fields, which makes it easy for magnetic field crosstalk to occur between the conductive bars, resulting in deviations in the detection results.

[0046] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0047] According to an embodiment of the present invention, on the one hand, a current detection component is provided, comprising:

[0048] At least two conductive bars 1 are arranged side by side and spaced apart along a third direction; the conductive bars 1 include a main section 11 and a detection section 13, the main section 11 extends along a first direction, and the detection section 13 is connected to the main section 11 and extends along a second direction; wherein the second direction is arranged non-parallel to the first direction;

[0049] The detection chip 3 and the circuit board 2 are installed on the circuit board 2 , and the detection chip 3 and the detection section 13 are opposite and spaced apart.

[0050] Both ends of the conductive bar 1 are connected to the circuit to be tested respectively, so that the current of the circuit to be tested is guided to the conductive bar 1 for detection.

[0051] In this embodiment, the number of the conductive bars 1 may be three, and the three conductive bars 1 are respectively connected to the three lines to be tested of the three-phase electricity, so as to facilitate the separate detection of the currents of the three lines to be tested of the three-phase electricity.

[0052] In some embodiments, the detection chip 3 includes a Hall detection element, and a detection plane of the Hall detection element is parallel to the second direction.

[0053] When the conductive row 1 is only a flat plate, since the three conductive rows 1 are arranged parallel to each other, the three conductive rows 1 will generate a magnetic field. Since the detection chip 3 is provided with a Hall detection element inside, the detection plane of the Hall detection element is arranged parallel to the three conductive rows 1. At this time, the magnetic field generated by the conductive rows 1 close to each other causes magnetic field crosstalk between the conductive rows 1, which easily leads to deviations in the detection results.

[0054] The conductive bar 1 of this embodiment includes a main section 11 and a detection section 13, and the detection section 13 is set at an angle to the extension direction of the main section 11. At this time, the magnetic field generated by the main section 11 is not parallel to the detection plane of the Hall detection element, and even the magnetic field generated by the main section 11 is perpendicular to the detection plane of the Hall detection element. This makes the main section 11 of the conductive bar not cause magnetic field crosstalk to the adjacent Hall detection element, thereby ensuring the detection accuracy. For application scenarios where multiple conductive bars are set parallel to each other, current detection can be performed more accurately.

[0055] The current detection component provided in the embodiment of the present invention can reduce the crosstalk between different phases to a greater extent and improve the accuracy of current detection of multiple lines at the same time by reasonably setting the structural form of the conductive bar 1 so that the conductive bar 1 adopts a special-shaped structural design.

[0056] After testing, it can meet the requirement that the crosstalk between different phases is less than 1.5%.

[0057] In some embodiments, the second direction is perpendicular to the first direction.

[0058] By making the second direction perpendicular to the first direction, that is, the main segment 11 and the detection segment 13 are perpendicular to each other, the magnetic field generated by the main segment 11 is perpendicular to the detection plane of the Hall detection element. When multiple conductive rows are arranged parallel to each other, the main segment 11 of the conductive row will not cause magnetic field crosstalk to the adjacent Hall detection element, thereby improving the accuracy of current detection in multiple lines at the same time.

[0059] In this embodiment, the detection chip 3 may be in the form of a coreless current sensor. When the chip is soldered to the circuit board 2, the power input terminal and the signal output terminal of the chip are each connected in parallel with a bypass capacitor to the ground.

[0060] In some embodiments, the detection chip 3 is disposed on a side of the circuit board 2 facing the conductive bar 1 .

[0061] By arranging the detection chip 3 on the side of the circuit board 2 facing the conductive bar 1 , the detection chip 3 can be brought closer to the detection section 13 of the conductive bar 1 , thereby reducing crosstalk between different phases as much as possible while meeting the detection requirements.

[0062] In some embodiments, in combination Figure 2 As shown, a portion of the detection segment 13 contracts along the third direction to form a neck portion 131. In a plane perpendicular to the second direction, the cross-sectional area of ​​the neck portion 131 is smaller than the cross-sectional area of ​​the detection segment 13 outside the neck portion 131. The detection chip 3 is opposite to the neck portion 131 and is spaced apart.

[0063] A constricted portion 131 is formed by contracting the detection section 13 partially along the third direction, and the detection chip 3 is arranged opposite to the constricted portion 131 and spaced apart, so that when the current on the conductive bar 1 completely flows through the constricted portion 131, the magnetic field generated by the constricted portion 131 can completely pass through the detection plane of the Hall detection element of the detection chip 3, thereby ensuring the accuracy of the detection.

[0064] In some embodiments, in combination Figure 2 As shown, at least one conductive bar 1 further includes: a turning section 12, the turning section 12 is connected between the main section 11 and the detection section 13, and the angle between the extending direction of the turning section 12 and the third direction is less than 90°;

[0065] Along the third direction, the distance between the detection segments 13 of two adjacent conductive bars 1 is M1, and the distance between the main segments 11 of two adjacent conductive bars 1 is M2; the turning segment 12 is suitable for making M1 larger than M2.

[0066] Since the turning section 12 is connected between the main section 11 and the detection section 13, and the angle between the extension direction of the turning section 12 and the third direction is less than 90°, that is, when the turning section 12 of one of the adjacent conductive bars 1 is bent, the spacing between the detection sections 13 of the adjacent conductive bars 1 will become larger, that is, the spacing M1 between the detection sections 13 of two adjacent conductive bars 1 along the third direction will be greater than the spacing M2 between the main sections 11 of the two adjacent conductive bars 1.

[0067] In some embodiments, M1 satisfies: M1>21 mm.

[0068] Optionally, the interval M1 between the detection segments 13 of two adjacent conductive bars 1 in this embodiment may be 21.5 mm, 22 mm, 25 mm, 28 mm, 30 mm, 32 mm, etc., or may be an interval formed by any two of the above values.

[0069] In some embodiments, along the third direction, the distance between the neck portions 131 of the detection segments 13 of two adjacent conductive bars 1 is M3, satisfying: M3>32 mm.

[0070] By increasing the spacing between the detection segments 13 of adjacent conductive bars 1 , the detection chip 3 can be moved further away from the detection segments 13 of adjacent conductive bars 1 , thereby reducing the magnetic field crosstalk between the conductive bars 1 and improving the accuracy of current detection of multiple lines at the same time.

[0071] In this embodiment, the included angle between the extending direction of the turning section 12 and the third direction is 0°, that is, the extending direction of the turning section 12 is parallel to the third direction.

[0072] In some embodiments, in combination Figure 2 As shown, there are three conductive bars 1 , and the conductive bars 1 on both sides along the third direction are provided with turning sections 12 , and the turning sections 12 of the conductive bars 1 on both sides along the third direction extend away from the conductive bar 1 in the middle.

[0073] There are three conductive bars 1 , which are a first conductive bar 101 , a second conductive bar 102 and a third conductive bar 103 along the third direction, wherein the second conductive bar 102 is located in the middle.

[0074] At this time, the second conductive bar 102 may not be provided with a turning section 12, and the turning section 12 of the first conductive bar 101 extends in a direction away from the second conductive bar 102 located in the middle, and the turning section 12 of the third conductive bar 103 also extends in a direction away from the second conductive bar 102 located in the middle. Thus, the distance between the detection section 13 of the first conductive bar 101 and the detection section 13 of the second conductive bar 102 becomes larger, and at the same time, the distance between the detection section 13 of the third conductive bar 103 and the detection section 13 of the second conductive bar 102 becomes larger, which can make the detection chip 3 further away from the detection section 13 of the adjacent conductive bar 1, thereby reducing the magnetic field crosstalk between the conductive bars 1 and improving the accuracy of current detection when multiple lines are simultaneously performed.

[0075] The conductive bar 1 of this embodiment further comprises a mounting section 14 , which is connected to one end of the detection section 13 away from the main section 11 . In this embodiment, the extending direction of the mounting section 14 may be parallel to the extending direction of the main section 11 .

[0076] The current detection assembly of this embodiment further includes a support 4 , which is connected to the mounting section 14 , so that the support 4 can be used to support and fix the conductive bar 1 .

[0077] In some embodiments, the distance A between the detection chip 3 and the detection section 13 satisfies: 0.5 mm≤A≤3 mm.

[0078] In this embodiment, the detection plane of the Hall detection element of the detection chip 3 is parallel to the second direction. Furthermore, the detection plane of the Hall detection element is parallel to the plane where the detection segment 13 is located.

[0079] The distance A between the detection chip 3 and the detection segment 13 may specifically be a vertical distance between the detection chip 3 and the detection segment 13 along the first direction.

[0080] Optionally, the distance A between the detection chip 3 and the detection segment 13 of the present embodiment can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc., or can be an interval formed by any two of the above values.

[0081] Preferably, in this embodiment, the distance A between the detection chip 3 and the detection section 13 may be 1.5 mm.

[0082] In some embodiments, the width of the constricted portion 131 along the third direction is NW, which satisfies: NW≤4mm; the extension length of the constricted portion 131 along the second direction is NL, which satisfies: 3mm≤NL; wherein the extension length NL of the constricted portion 131 along the second direction needs to be greater than the extension length of the detection chip 3 along the second direction. The width of the detection section 13 outside the constricted portion 131 along the third direction is BW, which satisfies: 11mm≤BW≤19mm; the thickness of the conductive bar 1 is BT, which satisfies 1mm≤BT≤5mm.

[0083] Optionally, the width NW of the neck portion 131 along the third direction of the embodiment can be 2 mm, 2.5 mm, 3.5 mm, 4 mm, etc., or can be an interval formed by any two of the above values.

[0084] Preferably, in this embodiment, the width NW of the neck portion 131 along the third direction may be 4 mm.

[0085] Optionally, the extension length NL of the neck portion 131 along the second direction of the present embodiment may be 3 mm, 3.5 mm, 4 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, etc., or may be an interval formed by any two of the above values.

[0086] Preferably, in this embodiment, the extension length NL of the neck portion 131 along the second direction may be 5 mm.

[0087] Optionally, the width BW along the third direction of the detection section 13 of this embodiment outside the necking portion 131 can be 11 mm, 11.5 mm, 12 mm, 13.5 mm, 15 mm, 15.5 mm, 16 mm, 16.5 mm, 17 mm, 18 mm, 19 mm, etc., or it can be an interval range formed by any two of the above values.

[0088] Preferably, in this embodiment, the width BW of the detection section 13 outside the neck portion 131 along the third direction may be 15 mm.

[0089] Optionally, the thickness BT of the conductive bar 1 of the present embodiment may be 1 mm, 1.5 mm, 2.5 mm, 3 mm, 4 mm, 4.5 mm, 5 mm, etc., or may be an interval formed by any two of the above values.

[0092] The conductive bar 1 defines at least one mounting hole 21 .

[0093] In order to prevent the deformation of the circuit board 2 as the temperature rises, which causes the distance parameters to change and thus causes the current accuracy to deteriorate, the conductive bar 1 of this embodiment is provided with at least one mounting hole 21.
