[0027] See also Figure 1 to Figure 2 , Figure 1 It is a schematic diagram of the overall structure of a controller according to an embodiment of the present application; Figure 2 It is a structural schematic diagram of a control board of an embodiment of a controller of the present application.

[0028] An embodiment of the present application provides a controller 10. The controller 10 includes a control board 11, a Hall chip 12 and a connection component 13. The Hall chip 12 is mounted on the control board 11. The connection component 13 includes a connector 131 and an iron core 132 formed in one piece, and the Hall chip 12 is accommodated in a receiving groove 133 formed by the iron core 132. The connection component 13 is used to transmit current.

[0029] As can be seen from the above structure, the connection component 13 is used to transmit current, and at this time, the current can be transmitted to the external structure for controlling the external structure. The Hall chip 12 is installed on the control board 11. At this time, the control board 11 and the Hall chip 12 are integrated, and there is no need to use additional wiring harnesses or pins to connect the two, so that the number of structural parts can be reduced to reduce costs. Due to the integrated setting between the Hall chip 12 and the control board 11, it is also possible to avoid wasting area on the control board 11, providing sufficient space for the setting of the remaining structural parts integrated on the control board 11. Furthermore, the Hall chip 12 is accommodated in the accommodating groove 133 formed by the iron core 132. On the one hand, since there will be a magnetic field around the iron core 132 during the use of the controller 10, the Hall chip 12 can determine the magnitude of the current transmitted by the connecting component 13 by measuring the magnitude of the magnetic field. The Hall chip 12 is accommodated in the accommodating groove 133 formed by the iron core 132, which can improve the accuracy of the current measured by the Hall chip 12. When the accuracy of the current measured by the Hall chip 12 is higher, the controller 10 can also improve the accuracy of the controller 10 controlling other external structures when applied to other external structures. On the other hand, it can also realize the integration between the Hall chip 12 and the iron core 132, and the competitiveness of the controller 10 can be effectively improved through the highly integrated and low-cost setting. Further, the connector 131 is integrally formed, and the connector 131 can have better structural strength at this time, so as to ensure the stability of the electrical signal transmission of the controller 10 during use.

[0030] Furthermore, the connection component 13 is arranged on the control board 11 and is used to transmit current. At this time, the connection component 13 can realize the electrical connection between the control board 11 and other external structures, so that the control board 11 can control the external structure through the connection component 13.

[0031] It should be noted that, in the embodiment of the present application, the iron core 132 is a C-shaped iron core 132, which has the advantages of small size, light weight, and high material utilization. Optionally, in some other embodiments, other iron cores 132 may also be used, which is not limited here.

[0032] In one embodiment of the present application, the two ends of the iron core 132 are bent relative to each other to form a receiving cavity (not shown in the figure), the connector 131 passes through the receiving cavity, and the portion of the connector 131 located in the receiving cavity and the iron core 132 is filled with a first injection molded part 134. The end surfaces at both ends are spaced apart to form a receiving groove 133 that is connected to the receiving cavity, and the Hall chip 12 is disposed in the receiving groove 133. Specifically, the two ends of the iron core 132 are bent relative to each other to form a receiving cavity, and the connector 131 passes through the receiving cavity. At this time, the connector 131 is partially located in the iron core 132, which can make the connection between the connector 131 and the iron core 132 more stable, so as to ensure the stability of the structure of the connecting component 13, so that during the later use of the controller 10, the connecting component 13 ensures the transmission of electrical signals due to its own stable structure. Furthermore, the first injection molded part 134 is filled between the part of the connector 131 located in the accommodating cavity and the iron core 132. On the one hand, the first injection molded part 134 can play a certain sealing role on the accommodating cavity to prevent debris from entering the control board 11 through the accommodating cavity and affecting the service life of other structural parts integrated on the control board 11; on the other hand, the provision of the first injection molded part 134 can also make the connection strength between the connector 131 and the iron core 132 higher, so as to better ensure the structural strength of the connecting component 13 itself. The end surfaces at both ends are spaced to form an accommodating groove 133 connected to the accommodating cavity, and the Hall chip 12 is accommodated in the accommodating groove 133. On the one hand, since there will be a magnetic field around the iron core 132 during the use of the controller 10, the Hall chip 12 can determine the magnitude of the current transmitted by the connecting component 13 by measuring the magnetic field, and the Hall chip 12 is accommodated in the accommodating groove 133 formed by the iron core 132, which can ensure the accuracy of the current measured by the Hall chip 12. When the current measured by the Hall chip 12 is more accurate, the controller 10 can improve the accuracy of controlling other external structures when applied to other external structures. On the other hand, the Hall chip 12 and the iron core 132 can be integrated, and the competitiveness of the controller 10 can be effectively improved through a highly integrated and low-cost setting.

[0033] See also Figures 1 to 3 , Figure 3 It is a partial structural diagram of a controller embodiment of the present application;

[0034] Furthermore, in order to protect the safety of the Hall chip 12 during use, in one embodiment of the present application, the controller 10 also includes a protective cover 111. One side of the protective cover 111 is set on the control board 11, and the other side extends into the accommodating cavity, wherein the Hall chip 12 is set in the protective cover 111. At this time, the protective cover 111 can protect the safety of the Hall chip 12 during the assembly of the controller 10, and prevent the Hall chip 12 from being bumped and deformed during the assembly process, thereby affecting the normal use of the controller 10 in the later stage. At the same time, the setting of the protective cover 111 can also make the Hall chip 12 play a certain fixing role, so that the controller 10 has a higher structural stability during the later use. Furthermore, since the other side of the protective cover 111 extends into the accommodating cavity, the Hall chip 12 can be located in the accommodating cavity, so that the accuracy of the Hall chip 12 in measuring the current can be greatly improved.

[0035] Specifically, the protective cover 111 includes a first cover body 112 and a second cover body 113 which are arranged opposite to each other, wherein the first cover body 112 and the second cover body 113 are integrally formed. At this time, the first cover body 112 and the second cover body 113 are integrally formed, and there is no need to use other fasteners to achieve connection and fixation, which can effectively reduce the number of structural parts. At the same time, the integral molding setting can also ensure the overall structural strength of the protective cover 111. The first cover body 112 is arranged on the control board 11, and the second cover body 113 is arranged in the receiving groove 133 of the iron core 132. Since the Hall chip 12 is arranged in the receiving groove 133, by setting the first cover body 112 on the control board 11 and the second cover body 113 in the receiving groove 133, the Hall chip 12 can be enclosed at this time to provide better protection for the Hall chip 12.

[0036] Furthermore, the first cover 112 has a first limit portion 114 connected to the control board 11, and the second cover 113 has a second limit portion 115 at one end away from the control board 11, and the projections of the first limit portion 114 and the second limit portion 115 on the control board 11 do not overlap at least partially. At this time, when the staff assembles the controller 10, the first cover 112 and the second cover 113 can be judged according to the projection positions of the first limit portion 114 and the second limit portion 115 on the control board 11, so as to avoid the first cover 112 and the second cover 113 being installed reversely during assembly. Therefore, the projections of the first limit portion 114 and the second limit portion 115 on the control board 11 are staggered, which can ensure the success rate of the staff in assembling the controller 10 and can also effectively improve the efficiency of assembly.

[0037] Specifically, there is no symmetry axis between the first limit portion 114 and the second limit portion 115, that is, the first limit portion 114 and the second limit portion 115 are an asymmetric structure. At this time, a through hole (not shown in the figure) is provided on the control board 11 corresponding to the first limit portion 114, so that during the assembly process by the staff, only the first limit portion 114 can be inserted into the through hole. Therefore, the asymmetric arrangement of the first limit portion 114 and the second limit portion 115 can effectively prevent the staff from inserting the second limit portion 115 into the through hole during the assembly process, thereby causing the first cover body 112 and the second cover body 113 to be installed upside down, thereby effectively improving the assembly success rate and assembly efficiency of the controller 10.

[0038] In one embodiment of the present application, a first notch 117 is provided on the end surface of the first cover 112 away from the second cover 113. Specifically, during the assembly of the controller 10, the staff can intuitively determine the positions of the first cover 112 and the second cover 113 according to the position of the first notch 117, and quickly set the first cover 112 on the control board 11. Therefore, the setting of the first notch 117 can facilitate the staff to visually identify the first cover 112 and the second cover 113, thereby playing a good fool-proof role to ensure the success rate and efficiency of assembly.

[0039] Furthermore, the controller 10 also includes a drive circuit (not shown in the figure) and a control circuit (not shown in the figure). The drive circuit and the control circuit are integrated on the control board 11. The drive circuit is used to drive other external structures, and the control circuit is used to control other external structures. The drive circuit and the control circuit are integrated on the control board 11. At this time, there is no need to use a wiring harness to connect the drive circuit and the control circuit to the control board 11, which can not only achieve a higher degree of integration, but also has the advantage of lower cost.

[0040] See also Figures 1 to 4 , Figure 4 It is a structural diagram of the connection components of a controller embodiment of the present application.

[0041] In one embodiment of the present application, the connecting member 131 includes a first end 1311 and a second end 1312, wherein the first end 1311 is connected to the control board 11 in the first direction X. The second end 1312 extends toward the second direction Y. The first direction X and the second direction Y are perpendicular. The connecting component 13 includes a support seat 1313. A limiting groove 1314 is formed on the support seat 1313. The connecting member 131 passes through the limiting groove 1314 to be plugged into the support seat 1313. The first end 1311 and the second end 1312 are respectively located at two ends of the support seat 1313. Specifically, when the controller 10 is in the working state, the first end 1311 is connected to the control board 11 in the first direction X, and the connection strength between the control board 11 and the connecting component 13 can be guaranteed at this time. The second end 1312 extends toward the second direction Y, which can also better ensure the connection between the connecting component 13 and other external structures. Furthermore, the connection component 13 is provided with a support seat 1313, and the support seat 1313 can play a certain supporting role for the connection component 13. On the one hand, it can prevent the connection member 131 from sinking due to its own gravity, which affects the transmission of current by the connection component 13. On the other hand, it can also prevent the Hall chip 12 and the receiving groove 133 from being separated, resulting in the Hall chip 12 not accurately detecting the current. Therefore, the setting of the support seat 1313 can play a good supporting role for the connection component 13, not only ensuring the transmission of current by the connection component 13, but also improving the accuracy of the detection result of the Hall chip 12 on the current. Secondly, a limiting groove 1314 is formed on the support seat 1313, and the connection member 131 passes through the limiting groove 1314 to be plugged into the support seat 1313, and the first end 1311 and the second end 1312 are respectively located at the two ends of the support seat 1313. The setting of the limiting groove 1314 can play a certain auxiliary role in the insertion of the connecting member 131 into the supporting seat 1313, thereby improving the efficiency of the connecting member 131 when being inserted into the supporting seat 1313, and further improving the assembly efficiency of the entire controller 10.

[0042] It should be noted that in the embodiment of the present application, the first end 1311 of the connector 131 is connected to the control circuit, and the second end 1312 of the connector 131 is connected to other external structures, so that the control circuit can accurately control other external structures.

[0043] In the embodiment of the present application, the limiting groove 1314 is a strip-shaped groove. Optionally, in some other embodiments, the limiting groove 1314 may also be a groove of some other shapes, which is not limited here.

[0044] Preferably, the first direction X is perpendicular to the second direction Y. Of course, in some other embodiments, the first direction X and the second direction Y may only intersect but not be perpendicular, which is not limited here.

[0045] Further, in an embodiment of the present application, a sealing ring 1315 is provided on one side of the limiting groove 1314 in the extension direction toward the second end 1312. The provision of the sealing ring 1315 can effectively prevent dust, debris, etc. from falling into the control board 11 from the gap between the support seat 1313 and the connecting member 131. Therefore, the provision of the sealing ring 1315 can play a good sealing role in the gap between the support seat 1313 and the connecting member 131, thereby effectively protecting the control board 11 and the other structural parts integrated on the control board 11, thereby effectively improving the service life of the control board 11 and the other structural parts integrated on the control board 11.

[0046] It should be noted that in the embodiment of the present application, the sealing ring 1315 is made of oil-resistant HNBR material, that is, hydrogenated nitrile rubber material. Of course, in some other embodiments, the sealing ring 1315 can also be made of other materials, which is not limited here.

[0047] In one embodiment of the present application, the connection component 13 is further provided with a glue dispensing groove 1316. The glue dispensing groove 1316 is provided at the plug-in position between the second end 1312 of the connection member 131 and the support seat 1313, and extends toward the extension direction of the second end 1312. The provision of the glue dispensing groove 1316 can improve the air tightness of the connection member 131 itself, thereby effectively preventing the oil and gas on the side of the second end 1312 of the connection member 131 from entering the interior of the control board 11 and affecting other components integrated on the control board 11.

[0048] It should be noted that the glue dispensing groove 1316 is made of a silicone material with excellent oil resistance and temperature shock resistance. At this time, it can effectively prevent the high-temperature oil and gas from corroding the glue dispensing groove 1316, thereby affecting the air tightness of the connector 131. Of course, in some other embodiments, the glue dispensing groove 1316 can also be made of other materials, which will not be repeated here.

[0049] See also Figures 1 to 5 , Figure 5 It is a schematic diagram of the overall structure of another embodiment of the controller of the present application.

[0050] In an embodiment of the present application, the controller 10 further includes a housing 16, and the control board 11 and the connecting component 13 are disposed in the housing 16. The provision of the housing 16 can provide a certain degree of protection for the control board 11 and the connecting component 13, so as to prevent the connecting component 13 and the control board 11 from being worn during the assembly process and the later use of the controller 10. Therefore, the provision of the housing 16 can provide a good protection for the control board 11 and the connecting component 13, so as to better improve the service life of the controller 10.

[0051] In one embodiment of the present application, the connector 131 is a three-phase connector 131, and the three-phase connector 131 includes a U copper bar 135, a V copper bar 136, and a W copper bar 137. Specifically, the U copper bar 135, the V copper bar 136, and the W copper bar 137 are arranged side by side, and each copper bar has a first end 1311 and a second end 1312. The first end 1311 of each copper bar is connected to the control board 11, and the second end 1312 is used to connect with other external structures. At this time, the control board 11 can be connected to other external structures through the U copper bar 135, the V copper bar 136, and the W copper bar 137, thereby realizing the output of electrical signals.

[0052] Furthermore, the U copper bar 135, the V copper bar 136 and the W copper bar 137 have the characteristics of strong transmission capacity and low loss. Therefore, the use of the U copper bar 135, the V copper bar 136 and the W copper bar 137 can improve the current transmission capacity and reduce the current loss, thereby making the current measured by the Hall chip 12 and the current transmitted to other external structures through the connector more consistent, thereby improving the control accuracy of the controller on other external structures. In addition, the use of the U copper bar 135, the V copper bar 136 and the W copper bar 137 has a simple structure, which can also make the entire controller 10 more convenient during assembly, thereby improving the assembly efficiency of the staff.

[0053] Optionally, in some other embodiments, the connecting member 131 may also be other connecting members 131 , which is not limited here.

[0054] It should be noted that in one embodiment of the present application, a power module 15 is also integrated on the control board 11. The power module 15 can convert direct current into three-phase electricity. The three-phase electricity flows into the external structure from the U copper bus 135, the V copper bus 136 and the W copper bus 137 in sequence, thereby realizing current transmission.

[0055] Another embodiment of the present application provides a vehicle (not shown in the figure). The vehicle includes the above-mentioned controller 10. Specifically, when the vehicle adopts the above-mentioned controller 10, the Hall chip 12 is installed on the control board 11 and is accommodated in the accommodating groove 133 formed by the iron core 132. At this time, during the use of the controller 10, there will be a magnetic field around the iron core 132. Therefore, the Hall chip 12 can determine the magnitude of the current transmitted by the connecting component 13 by measuring the magnetic field, so that the control circuit on the controller 10 can better control the operation of the vehicle. At the same time, since the Hall chip 12 is installed on the control board 11, at this time, the Hall chip 12 is integrated with the control board 11, and the Hall chip 12 and the control board 11 can be connected without the need for additional wiring harnesses or pins, etc., which can reduce the number of structural parts such as wiring harnesses or pins, and reduce the production cost of the controller 10 while also reducing the production cost of the vehicle. The connecting component 13 can also realize the electrical connection between the vehicle body and the control board 11. The first end 1311 of the connecting component 13 is connected to the control circuit, and the second end 1312 is connected to the vehicle body. Thus, the control circuit on the control board 11 can control the vehicle body to better control the operation of the vehicle.

[0056] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation.

In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does 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 to the present application.

[0057] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
