[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0039] The following is a reference appendix. Figure 1-9 A control device 100 according to an embodiment of the present invention is described.
[0040] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 According to an embodiment of the present invention, the control device 100 includes: a housing 10, a circuit board 20, and a conductive element 30.
[0041] Specifically, the housing 10 has a receiving cavity; the circuit board 20 is disposed in the receiving cavity, and the circuit board 20 has multiple solder points, that is, the circuit board 20 has two, three, four or more solder points, which constitute a first solder point group 21 and a second solder point group 22. In the direction from the center of the circuit board 20 toward the periphery, the first solder point group 21 and the second solder point group 22 are arranged at intervals and cooperate to define a groove 23 extending circumferentially along the circuit board 20; the conductive element 30 is connected to the housing 10 and located in the receiving cavity, and at least a part of the conductive element 30 is fitted in the groove 23, that is, either a part of the conductive element 30 is fitted in the groove 23, or the entire conductive element 30 is fitted in the groove 23, and is connected to multiple solder points of the first solder point group 21 and the second solder point group 22, so that the circuit board 20 is grounded through the conductive element 30 and the housing 10.
[0042] For example, such as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the circuit board 20 has multiple solder joints. A portion of these solder joints form a first solder joint group 21, with the solder joints of the first solder joint group 21 arranged at intervals along the circumference of the circuit board 20 and extending in a ring. A portion of these solder joints form a second solder joint group 22, with the solder joints of the second solder joint group 22 arranged at intervals along the circumference of the circuit board 20 and extending in a ring. In the arrangement direction of the first solder joint group 21 and the second solder joint group 22, a groove 23 is defined between adjacent solder joints of the first solder joint group 21 and the second solder joint group 22, so that the groove 23 is formed as a ring extending circumferentially along the circuit board 20. A conductive element 30 is adapted to the extension shape of the groove 23, and a portion of the conductive element 30 fits within the groove 23, so that the conductive element 30 is electrically connected to both the solder joints of the first solder joint group 21 and the solder joints of the second solder joint group 22. Preferably, both the conductive element 30 and the housing 10 are metal parts, thereby enabling the circuit board 20 to be grounded through the conductive element 30 and the housing 10.
[0043] It should be noted that the control device 100 can be applied to intelligent driving systems, air conditioning systems and battery pack thermal management systems. Since there is electromagnetic interference between adjacent control devices 100, the circuit board 20 needs to be grounded through the housing 10 to form a Faraday cage inside the housing 10, thereby reducing electromagnetic interference between adjacent control devices 100.
[0044] The control device 100 of the present invention is provided with a conductive element 30. The conductive element 30 abuts against the first solder joint group 21 and the second solder joint group 22 in the conductive groove and is electrically connected to the first solder joint group 21 and the second solder joint group 22, thereby enabling the circuit board 20 to be grounded and preventing electromagnetic interference from adjacent control devices 100. At the same time, the conductive element 30 is in abutting contact with the first solder joint group 21 and the second solder joint group 22, and the conductive element 30 will not crush the solder joints on the circuit board 20. Therefore, even if the housing 10 is disassembled and the circuit board 20 is reassembled, the conductive element 30 will not lose contact with the solder joints. This avoids the electromagnetic shielding effect being affected by maintenance operations, thereby ensuring that the control device 100 can be maintained normally and reducing the operating cost of the control device 100.
[0045] Furthermore, compared to the existing technology where copper sheets are placed in contact with solder joints, ensuring that the copper sheet can contact each solder joint requires a high-precision plane, which leads to processing difficulties. However, with the matching form of the conductive element 30 and the groove 23 in this application, the conductive element 30 is easy to process, and the groove 23 is formed by the solder joints of the adjacent first solder joint group 21 and the second solder joint group 22. Therefore, the processing difficulty can be reduced, and the connection stability between the conductive element 30 and the solder joints of the first solder joint group 21 and the second solder joint group 22 can be effectively ensured, thereby ensuring the electromagnetic shielding effect of the control device 100.
[0046] Furthermore, the groove 23 guides the conductive component 30, facilitating quick positioning of the conductive component 30 and thus improving the installation and positioning efficiency of the conductive component 30 and the groove 23.
[0047] According to an embodiment of the present invention, the control device 100 is provided with a conductive element 30. The conductive element 30 abuts against the first solder joint group 21 and the second solder joint group 22 in the conductive groove. The conductive element 30 will not crush the solder joints on the circuit board 20, which can avoid the electromagnetic shielding effect being affected by maintenance operations, thereby ensuring that the control device 100 can be maintained normally. At the same time, the groove 23 guides the conductive element 30, which facilitates the quick positioning of the mating position of the conductive element 30, thereby improving the installation and positioning efficiency of the conductive element 30 and the groove 23.
[0048] According to some embodiments of the present invention, with reference to Figure 5 and Figure 6The multiple solder joints include first solder joints 211 and second solder joints 221. The first solder joint group 21 includes multiple first solder joints 211 arranged at intervals along the circumference of the circuit board 20. That is, the first solder joint group 21 includes two, three, four or more first solder joints 211 arranged at intervals along the circumference of the circuit board 20. The second solder joint group 22 includes multiple second solder joints 221 arranged at intervals along the circumference of the circuit board 20. That is, the second solder joint group 22 includes two, three, four or more second solder joints 221 arranged at intervals along the circumference of the circuit board 20. In the circumference of the circuit board 20, at least some of the first solder joints 211 and the second solder joints 221 are staggered. That is, some of the first solder joints 211 and the second solder joints 221 may be staggered, or all of the first solder joints 211 and all of the second solder joints 221 may be staggered.
[0049] In this way, multiple first solder points 211 form a first solder point group 21, which ensures the electromagnetic shielding effect of the first solder point group 21 on the circuit board 20. Multiple second solder points 221 form a second solder point group 22, which ensures the electromagnetic shielding effect of the second solder point group 22 on the circuit board 20. At the same time, the cooperation of the first solder points 211 and the second solder points 221 can further enhance the electromagnetic shielding effect on the circuit board 20. In addition, the staggered arrangement of the first solder points 211 and the second solder points 221 can facilitate the positioning of the conductive component 30 in the groove 23, and at the same time, prevent the conductive component 30 from sliding out of the groove 23, ensuring the stability of the conductive component 30 in the groove 23, and thus effectively ensuring that the circuit board 20 is stably grounded through the conductive component 30.
[0050] For example, such as Figure 5 and Figure 6 As shown, the first solder joint group 21 includes multiple first solder joints 211, which are arranged in a ring along the circumference of the circuit board 20. The second solder joint group 22 includes multiple second solder joints 221, which are arranged in a ring along the circumference of the circuit board 20. Adjacent first solder joints 211 and second solder joints 221 are arranged at intervals in both the front-back direction and the left-right direction, so that adjacent first solder joints 211 and second solder joints 221 are staggered.
[0051] According to some optional embodiments of the present invention, refer to Figure 5 and Figure 6 In the circumferential direction of the circuit board 20, multiple first solder points 211 and multiple second solder points 221 are arranged alternately. As a result, the density of contact between the conductive component 30 and the solder points can be increased in the circumferential direction of the circuit board 20, thereby effectively ensuring the electromagnetic shielding effect. At the same time, the conductive component 30 can be stably confined within the groove 23, effectively preventing the conductive component 30 from detaching from the groove 23.
[0052] For example, with Figure 6Taking the partial groove 23 shown as an example, the first solder point 211 is arranged on the right side in front of the second solder point 221, and the first solder point 211 and the second solder point 221 define a groove 23 extending in the front-back direction.
[0053] According to some optional embodiments of the present invention, refer to Figure 5 and Figure 6 In the circumferential direction of the circuit board 20, the spacing between the first solder joint 211 and the two adjacent second solder joints 221 is not equal. Therefore, the distance between the first solder joint 211 and the two adjacent second solder joints 221 can be adjusted according to actual needs, thereby ensuring the versatility of the control device 100.
[0054] For example, such as Figure 5 As shown, the distance between the first solder point 211 at position A and the second solder point 221 on the left rear side is less than the distance between the second solder point 221 on the left front side.
[0055] According to some embodiments of the present invention, with reference to Figure 5 , Figure 7 and Figure 8 In the direction from the opening of the groove 23 toward the bottom wall, the width of at least a portion of the conductive element 30 gradually decreases; that is, either a portion of the conductive element 30 gradually decreases in width, or the entire width of the conductive element 30 gradually decreases. This ensures that the conductive element 30 can abut against the first solder joint 211 and the second solder joint 221 within the groove 23, thereby guaranteeing the electromagnetic shielding effect. Furthermore, the conductive element 30 can adapt to grooves 23 of various widths, thus improving its versatility.
[0056] For example, such as 5. Figure 7 and Figure 8 As shown, the overall width of the conductive element 30 gradually decreases from top to bottom.
[0057] According to some optional embodiments of the present invention, refer to Figure 6 , Figure 8 and Figure 9 In the thickness direction of circuit board 20 (e.g.) Figure 8 On the vertical direction shown, the side surface of the conductive element 30 facing the bottom wall of the groove 23 (e.g., in the vertical direction shown) Figure 8 The lower surface shown is the first surface 31. The width of the first surface 31 is less than the width of the groove 23, and the maximum width of the conductive element 30 is greater than the width of the groove 23.
[0058] In this way, limiting the width of the first surface 31 ensures that the end of the conductive element 30 facing the bottom wall of the groove 23 can extend into the groove 23. At the same time, limiting the maximum width of the conductive element 30 ensures that both sides of the conductive element 30 can abut against the first solder joint 211 and the second solder joint 221 on both sides, thereby enabling the circuit board 20 to be grounded through the conductive element 30 and the housing 10.
[0059] For example, such as Figure 6 , Figure 8 and Figure 9 As shown, d1 represents the distance between the first solder joint 211 and the second solder joint 221 in the left-right direction. The lower surface of the conductive component 30 is the first surface 31. d2 represents the width of the first surface 31 in the left-right direction. d2 is less than d1. The upper end of the conductive component 30 is the position where the conductive component 30 has the maximum width. This ensures that the left and right sides of the conductive component 30 can respectively abut against the first solder joint 211 and the second solder joint 221.
[0060] According to some optional embodiments of the present invention, refer to Figure 6 , Figure 8 and Figure 9 In the direction from the bottom wall of the groove 23 toward the opening, the conductive element 30 is in the width direction (e.g. Figure 9 The conductive component 30 shown extends at an angle in the left-right direction, with both sides inclined away from each other. This ensures that the two sides of the conductive component 30 in the width direction can abut against the first solder joint 211 and the second solder joint 221 on both sides, thereby effectively ensuring that the circuit board 20 can be stably grounded and ensuring electromagnetic shielding effect.
[0061] For example, such as Figure 6 , Figure 8 and Figure 9 As shown, in the direction from bottom to top, the left side surface of the conductive element 30 extends to the left at an angle, and the right side surface of the conductive element 30 extends to the right at an angle.
[0062] According to some optional embodiments of the present invention, refer to Figure 6 , Figure 8 and Figure 9 The conductive element 30 is in the width direction (e.g. Figure 9 The conductive component 30 shown has two curved surfaces on its left and right sides (in the left and right direction) that bulge in opposite directions. Therefore, during the contact between the conductive component 30 and the solder joint, the curved surfaces prevent the conductive component 30 from damaging the solder joint, thus protecting it. Therefore, even when repeatedly disassembling and reassembling the housing 10 and the circuit board 20, the conductive component 30 can still maintain normal contact with the solder joint.
[0063] For example, such as Figure 6 , Figure 8 and Figure 9As shown, in the direction from bottom to top, the left surface of the conductive element 30 is formed as an arc surface extending to the left at an angle, and the right surface of the conductive element 30 is formed as an arc surface extending to the right at an angle.
[0064] Furthermore, such as Figure 6 , Figure 8 , Figure 9 As shown, the height of the conductive component 30 in the vertical direction is greater than the height of the solder joint in the vertical direction, thus ensuring that the conductive component 30 can properly abut against the solder joints on both sides of the groove 23.
[0065] According to some embodiments of the present invention, with reference to Figure 1 and 5 Multiple solder joints of the first solder joint group 21 and multiple solder joints of the second solder joint group 22 are arranged in a ring along the circumference of the circuit board 20, and the first solder joint group 21 is located inside the second solder joint group 22. Electrical components (not shown in the figure) are provided on the circuit board 20, and the electrical components are located inside the first solder joint group 21.
[0066] In this way, the first solder joint group 21 and the second solder joint group 22 shield the electrical components on the inside, thereby effectively shielding the electromagnetic signals of the electrical components on the radial inside of the first solder joint group 21 and the second solder joint group 22. Therefore, it can prevent the electromagnetic interference of the control device 100 from affecting the adjacent control device 100. At the same time, the first solder joint group 21 and the second solder joint group 22 work together to prevent the electromagnetic interference of the adjacent control device 100 from affecting the control device 100 of this application.
[0067] For example, such as Figure 1 and Figure 5 As shown, the first solder joint group 21 has multiple first solder joints 211 extending in a ring along the circumference of the circuit board 20, and the second solder joint group 22 has multiple second solder joints 221 extending in a ring along the circumference of the circuit board 20. The first solder joint group 21 is located radially inside the second solder joint group 22, and the electrical components on the circuit board 20 are located radially inside the first solder joint group 21.
[0068] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 5 The circuit board 20 is also provided with a connector 24 connected to the circuit board 20. The connector 24 is arranged outside the second solder joint group 22. This prevents the Faraday cage formed between the conductive component 30 and the solder joint from affecting the connection between the connector 24 and the external structure, thereby ensuring that the circuit board 20 can be electrically connected to the external structure normally, and thus ensuring that the control device 100 can work normally.
[0069] For example, such as Figure 1 and Figure 5As shown, a connector 24 is provided on the front side of the circuit board 20. The connector 24 is located on the radial outer side of the second solder joint group 22. The circuit board 20 is electrically connected to the external structure through the connector 24.
[0070] According to some embodiments of the present invention, with reference to Figure 1 and Figure 5 The housing 10 includes a cover plate 11 and a bottom shell 12, wherein the bottom shell 12 is located in the thickness direction of the circuit board 20 (e.g., ...). Figure 1 On one side of the circuit board 20 shown in the vertical direction (e.g.) Figure 1 The bottom shell 12 shown is open on its lower side, and the cover plate 11 covers the open side of the bottom shell 12 and cooperates with the bottom shell 12 to define the receiving cavity. Thus, the housing 10 is a split part, which not only facilitates the installation of the circuit board 20 with the housing 10, but also facilitates the processing of the housing 10. At the same time, the split cover plate 11 facilitates the maintenance of the circuit board 20, thereby effectively improving the service life of the control device 100.
[0071] For example, such as Figure 1 and Figure 5 As shown, the lower side of the bottom shell 12 is open, and the cover plate 11 is located on the lower side of the bottom shell 12 and covers the open side of the bottom shell 12. The cover plate 11 and the bottom shell 12 cooperate to define the receiving cavity. The circuit board 20 extends in the horizontal direction and is disposed in the receiving cavity.
[0072] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 3 and Figure 4 The conductive element 30 is integrally formed with the bottom shell 12 or the cover plate 11. This ensures the strength of the conductive element 30 and prevents it from being damaged. At the same time, the conductive element 30 directly transmits current to the bottom shell 12 or the cover plate 11, thereby improving the conductivity and ensuring the electromagnetic shielding effect.
[0073] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the conductive component 30 and the bottom shell 12 are integrally formed, thereby ensuring the strength of the conductive component 30. Preferably, the conductive component 30 and the bottom shell 12 are integrally cast, which can ensure both the structural strength of the conductive component 30 and the processing efficiency.
[0074] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The bottom shell 12 has a support edge 121 extending outward from the receiving cavity around its open periphery. The circuit board 20 is supported on the support edge 121, and the conductive element 30 is disposed on the support edge 121. In the direction perpendicular to the thickness of the circuit board 20 (e.g., ...), Figure 1In the projection plane of the circuit board 20 (vertical direction), at least some of the solder joints and at least some of the conductive parts 30 are located within the projection range of the support edge 121. That is, it is possible that some of the solder joints and some of the conductive parts 30 are located within the projection range of the support edge 121, or it is possible that the overall projection of the solder joints and the overall projection of the conductive parts 30 are both located within the projection range of the support edge 121.
[0075] In this way, the support edge 121 can support the periphery of the circuit board 20, thereby saving the parts for fixing the circuit board 20 and reducing production costs. At the same time, when the bottom shell 12 is engaged with the circuit board 20, the conductive component 30 can directly engage with the groove 23 of the circuit board 20, thereby enabling quick positioning and installation, and thus improving assembly efficiency.
[0076] For example, such as Figure 1 and Figure 2 As shown, the lower periphery of the bottom shell 12 is provided with a support edge 121 extending outward from the receiving cavity. The periphery of the circuit board 20 is supported on the support edge 121. The overall projection of the solder joint and the overall projection of the conductive component 30 are both located within the projection range of the support edge 121. When the shell 10 and the circuit board 20 are engaged, the conductive component 30 can be directly engaged in the groove 23.
[0077] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The cover plate 11, circuit board 20, and bottom shell 12 are fastened together by threaded fasteners 40. This ensures that the circuit board 20 is stably fixed to the cover plate 11 and bottom shell 12, preventing the cover plate 11 from shaking within the cavity and thus protecting the circuit board 20. Furthermore, the fasteners 40 provide a detachable connection, facilitating maintenance of the circuit board 20 and the shell 10.
[0078] For example, such as Figure 1 As shown, the cover plate 11 is located on the lower side of the bottom shell 12, the circuit board 20 is located between the bottom shell 12 and the cover plate 11, and the fastener 40 passes through the cover plate 11, the circuit board 20 and the bottom shell 12 from bottom to top to fix the cover plate 11, the circuit board 20 and the bottom shell 12.
[0079] According to a second aspect embodiment of the vehicle, referring to Figure 1 , Figure 2 and Figure 3 This includes the control device 100 of the first aspect of this embodiment.
[0080] According to an embodiment of the present invention, the vehicle is equipped with a control device 100 as described in the first aspect embodiment, and a conductive element 30 is provided. The conductive element 30 abuts against the first solder joint group 21 and the second solder joint group 22 in the conductive groove. The conductive element 30 will not crush the solder joints on the circuit board 20, which can avoid the electromagnetic shielding effect being affected by maintenance operations. This ensures that the control device 100 can be maintained normally. At the same time, the groove 23 guides the conductive element 30, which facilitates quick positioning of the mating position of the conductive element 30, thereby improving the installation and positioning efficiency of the conductive element 30 and the groove 23.
