Description

Technical Field

[0001] The utility model relates to the field of power generation starters, in particular to a support structure and a Hall component for positioning a Hall element. Background Art

[0002] In the field of brushless motors, the brushless motor Hall component is an electrical control device, whose main function is to change the direction of current at a certain position, so that the motor coil produces opposite magnetic poles to realize the commutation operation of the motor. In the rotor structure of the generator starter, a magnet is arranged. Combined with the corresponding magnetic pole setting, the phase position of the rotor rotation can be obtained through the Hall sensor, and the differentially set magnetic poles are used as the signal to trigger ignition. Therefore, it is necessary to position the Hall sensor; in order to achieve positioning, it is necessary to put a positioning sleeve on the Hall sensor, but because a Hall sensor has 3 pins, a Hall component corresponding to 4 Hall sensors needs to be put on 12 sleeves. Since the Hall sensor pin spacing is small, the size of the sleeve is also limited, which increases the difficulty of processing operations. The production cost and efficiency are relatively high. Therefore, it is necessary to make improvements. Utility Model Content

[0003] The utility model provides a support structure and a Hall component for positioning a Hall element, so as to facilitate the rapid insertion and positioning of the Hall element, ensure the consistency of the position and installation quality of the Hall element, and thus improve the reliability and stability of the product.

[0004] To achieve the purpose of the utility model, a support structure for positioning a Hall element is provided herein, comprising: an integrally formed base and a plurality of support columns; the support columns are perpendicular to the base as a whole, and are provided with pin guide grooves for inserting the pins of the Hall element to support and position the Hall element, and enable the pins of the Hall element to pass through the base for welding.

[0005] Furthermore, the base is in an arc-shaped strip; correspondingly, the support columns are distributed on the same arc, or on concentric arcs.

[0006] Furthermore, the number of the support columns is no less than 4.

[0007] Furthermore, among the plurality of support columns, at least one support column has a height different from that of the other support columns.

[0008] The utility model also proposes a Hall component, comprising a support structure for positioning a Hall element as described above, and also comprising the same number of Hall elements as the supporting columns, and a circuit board, wherein the pins of the Hall elements pass through the pin guide grooves of the supporting columns and are welded and fixed on the circuit board.

[0009] Furthermore, it also includes a protective shell, which is used to accommodate the circuit board, the support column and the Hall element. The protective shell is provided with a pin socket, which is used to connect with the signal of the circuit board and facilitate the transmission of the sensor signal to the outside.

[0010] Furthermore, the circuit board is provided with a mounting hole to facilitate the fixing of the circuit board to the base and / or the protective shell; the protective shell is also provided with a fixing hole to facilitate the fixed installation of the protective shell.

[0011] Through the support structure for positioning the Hall element, the action of plugging multiple sleeves for one Hall element can be simplified to only one plugging action, and because the support column itself is integrally formed with the base and relatively fixed, it also avoids the sleeve plugging error or sleeve falling off during the process, thereby improving production efficiency and reliability. The Hall assembly provided by this solution integrates the Hall element, support structure, circuit board and other components to form an integrated structure, which simplifies the assembly process and improves the overall stability and reliability of the product.

[0019] The embodiments of the utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The example implementation methods can be implemented in various forms and should not be construed as being limited to the examples set forth herein; on the contrary, these implementation methods are provided so that the utility model will be more comprehensive and complete, and the concept of the example implementation methods will be fully conveyed to those skilled in the art. Wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be construed as limiting the present invention. In the description of the present invention, it should be understood that, unless otherwise specified, the meaning of "multiple" and "several" is two or more.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" 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 mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of 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.

[0021] This embodiment provides a support structure for positioning a Hall element, such as Figure 1 As shown, it includes: an integrally formed base 1, a plurality of support columns 2 and a clamping column 3 for clamping and fixing; the support column 2 is perpendicular to the base 1 as a whole, and a pin guide groove is provided on the support column 2 for inserting the pins of the Hall element to support and position the Hall element, and enable the pins of the Hall element to pass through the base for welding. The base 1 is in the shape of an arc strip, and correspondingly, each support column is distributed on the same arc, or on concentric arcs, thereby enabling the Hall element to adapt to the magnetic pole position of the rotor. The number of the support columns 2 is not less than 4. In this embodiment, there are 4 support columns, corresponding to fixing the four Hall elements A, B, C, and D, as shown in FIG. Figure 2As shown. On the same support column 2, at least three pin guide grooves are included. On the cross section of the same support column 2, the opening directions of adjacent pin guide grooves are opposite. Since the general Hall element has three pins, the three pin guide grooves can fix the Hall element relatively stably. The opening directions of adjacent pin guide grooves are opposite, so that it can prevent deflection. Especially when wave soldering is performed during the production process, it is ensured that the Hall element will not deflect like the sleeve support, or it is necessary to use additional tape to keep its position fixed. At the same time, when the size adjustment is required, this structure can also be compatible. Whether it is to reduce the corresponding height of the formed support column structure or adjust the mold, it is more convenient. Among the several support columns, at least one support column has a different height from the other support columns. The clamping column 3 of the base 1 for clamping and fixing is connected to the circuit board 4. In this embodiment, the height of the three support columns is the same, and the height of the other support column is different. The Hall element fixed by the support columns with different heights is used to obtain the sensor signal of the corresponding magnetic pole of the trigger ignition of the generator starter. A clamping column 3 is provided on one side of the base away from the supporting column, so as to facilitate the base to be clamped and fixed with the corresponding structure of the circuit board.

[0022] This embodiment also provides a Hall component, comprising the above-mentioned support structure for positioning the Hall element, and also comprising the same number of Hall elements as the support column, and a circuit board, wherein the pins of the Hall element pass through the pin guide grooves of the support column 2 and are welded and fixed on the circuit board. Figure 3 As shown, correspondingly, the circuit board 4 is provided with a mounting hole 6 so that the circuit board can be fixedly connected with the clamping column 3 of the base 1. When viewed from the bottom of the circuit board, Figure 2 As shown in the figure, the exposed clamping column 3 is shown in the figure; therefore, during processing, the support structure can be directly clamped and fixed on the circuit board, and then the Hall element can be plugged into the support column and soldered by wave soldering. The circuit board 4 is provided with a pin socket 7, which is used to connect with the signal of the circuit board and facilitate the transmission of the sensor signal to the outside. The pins of the Hall element are welded as shown in the figure. Figure 2 5. Compared with the prior art, the multiple insertion of the pin sleeve is omitted, the pin sleeve is prevented from falling off, and the necessary fixing means such as tape pasting to avoid the tilt of the Hall element during wave soldering are saved, the production process efficiency is improved, and the quality of the product is guaranteed.

[0023] In this embodiment, Figure 4-Figure 7 As shown, the Hall component also includes a protective housing 8, which is used to accommodate the circuit board 4, the support column 2 and the Hall element. The protective housing is also provided with fixing holes 9 to facilitate the fixed installation of the protective housing 8, that is, the protective housing is connected to the stator coil of the motor with screws, and the Hall component is fixed by fixing the protective housing. Figure 7As shown, a protective cover 8-1 corresponding to the support column 2 is provided on the protective housing 8. Due to the integrated structure and unified assembly method of the Hall component, the consistency of the position and installation quality of the Hall element can be guaranteed, thereby improving the reliability and stability of the product; the integrated design makes the component easier to maintain and replace, reducing the time and cost of maintenance and increasing the service life of the product.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
