[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the contour of the corresponding component itself. One side of the circuit board body refers to the side of the body facing the metal shell or the side away from the metal shell. In addition, the terms "first", "second", "third", etc. used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0024] The circuit board in the exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0025] refer to Figures 1 to 3 As shown, in the first aspect of the present disclosure, a circuit board is provided, comprising a body 1 and a filling unit 3, wherein the body 1 comprises a connection portion 2 for connecting to a metal shell 7; the filling unit 3 is arranged on at least one side of the body 1, and the filling unit 3 comprises a plurality of filling portions 31 of different heights, which are used to fill at least part of the gap generated after the body 1 is connected to the metal shell 7. After the body 1 is connected to the metal shell 7 through the connection portion 2, the metal shell 7 will be deformed to a certain extent, so that there are gaps of different sizes between the metal shell 7 and the body 1. At this time, the filling portions 31 of different heights can fill these gaps. For example, the filling portion 31 with a lower height can be arranged in an area with a smaller gap, while the filling portion 31 with a higher height can be arranged in an area with a larger gap, so as to fill at least part of the gap between the body 1 and the metal shell 7. In this way, the gap between the body 1 and the metal shell 7 can be reduced, the shielding performance of the metal shell 7 can be improved, and the interference of the outside world to the electronic and electrical modules on the body 1 can be reduced or even avoided, thereby ensuring the normal operation of the circuit board.

[0026] It should be noted that the connection portion 2 can be constructed to be adapted to a connection hole of a fastener 9 such as a bolt or a screw, and the fastener 9 can connect the body 1 and the metal shell 7 together through the connection hole.

[0027] In some embodiments of the present disclosure, the filling unit 3 can be configured to be softly overlapped with the metal shell 7, that is, one end of the filling portion 31 is connected to the body 1, and the other end can be against the metal shell 7. The soft overlap between the filling unit 3 and the metal shell 7 can ensure the shielding effect of the metal shell 7, reduce electromagnetic interference, reduce the vibration of the circuit board and the metal shell 7, and prevent the vibration from damaging the circuit board. In addition, it can also reduce the noise generated by the vibration of the circuit board and the metal shell 7, thereby improving its quiet performance.

[0028] Specifically, the filling portion 31 can be constructed as a tin dot 32, that is, the main body 1 and the metal shell 7 are softly overlapped together through the tin dot 32. The tin dot 32 is used as the filling portion 31. On the one hand, because the tin dot 32 is relatively soft, it can reduce the damage to the circuit board caused by vibration. On the other hand, the tin dot 32 is formed faster and can be quickly formed on the main body 1, which can improve production efficiency.

[0029] In some embodiments, Figure 3 As shown, the filling unit 3 includes a first tin point group 4 arranged outside the connection part 2; the first tin point group 4 includes a plurality of tin points 32 whose heights gradually increase along the direction away from the connection part 2. Since the connection between the body 1 and the metal shell 7 on the side close to the connection part 2 is relatively tight, the gap on the side close to the connection part 2 is relatively small, and accordingly, the height of the tin points 32 on the side close to the connection part 2 can be relatively low, while on the side away from the connection part 2, since the metal shell 7 may be deformed to a certain extent after being connected to the body 1, the gap on the side away from the connection part 2 will be relatively large, so the tin points 32 with higher heights can be arranged on the side away from the connection part 2.

[0030] Among them, the first tin point group 4 includes a plurality of tin points 32 whose heights gradually increase along the direction away from the connecting portion 2. It can be understood that the tin points 32 of the first tin point group 4 in the direction away from the connecting portion 2 have a tendency of gradually increasing heights. Specifically, the height of the tin point 32 on the side close to the connecting portion 2 of two adjacent tin points 32 in the first tin point group 4 can be less than or equal to the height of the tin point 32 on the side away from the connecting portion 2, and the height of at least one of the plurality of tin points 32 located on the side away from the connecting portion 2 is greater than the height of the tin point 32 on the side close to the connecting portion 2. For example, the first tin point group 4 can include a first tin point position, a second tin point position and a third tin point position, each of which has a plurality of tin points 32, wherein the first tin point position The heights of the multiple tin points 32 can be the same, or the height of the tin point 32 close to the connecting part 2 is smaller than the height of the tin point 32 away from the connecting part 2; the heights of the multiple tin points 32 in the second tin point position can all be higher than the height in the first tin point position, and the heights of the multiple tin points 32 in the second tin point position can be the same, or the height of the tin point 32 close to the connecting part 2 is smaller than the height of the tin point 32 away from the connecting part 2. Similarly, the heights of the multiple tin points 32 in the third tin point position can all be higher than the height of the tin points 32 in the second tin point position, and the heights of the multiple tin points 32 in the third tin point position can be the same, or the height of the tin point 32 close to the connecting part 2 is smaller than the height of the tin point 32 away from the connecting part 2.

[0031] In some embodiments of the present disclosure, Figure 3As shown, there are multiple first tin point groups 4, and the multiple first tin point groups 4 are arranged at circumferential intervals along the connecting part 2. The arrangement of the multiple first tin point groups 4 can make the outer side of the connecting part 2 have more tin points 32, so as to further reduce the gap between the main body 1 and the metal shell 7, so as to improve the shielding performance of the metal shell 7 and ensure the normal operation of the circuit board.

[0032] In some embodiments, Figure 1 and Figure 2 As shown, since the body 1 of the circuit board is generally a rectangular sheet structure, the area near the four corners of the body 1 can be provided with a connection part 2, so that the filling unit 3 can also include a second tin point group 5 arranged between two adjacent connection parts 2, and the second tin point group 5 includes a plurality of tin points 32, and the heights of at least two tin points in the second tin point group 5 are different. After one of the two connection parts 2 first connects the body 1 and the metal shell 7 together, the other connection part 2 connects the body 1 and the metal shell 7 again, which will cause a certain amount of deformation of the metal shell 7, so a gap of different sizes can be formed between the two connection parts 2. Therefore, the higher tin point 32 of the two tin points 32 can be set in the area with a larger gap, and the lower tin point 32 can be set in the area with a smaller gap.

[0033] Among them, since the farthest position relative to the two adjacent connecting parts 2 is located at the center of the two, that is, the gap at the center position is the largest, and the gap is smaller as the position is closer to the connecting part 2, based on this, the height of the tin point 32 gradually decreases as the middle of the two connecting parts 2 moves toward the two connecting parts 2.

[0034] Of course, the gradual decrease in height of the tin point 32 from the middle of the two connecting parts 2 toward the two connecting parts 2 means that the height of the tin point 32 has a decreasing trend, that is, the heights of the tin points 32 may be consistent among the multiple tin points 32 .

[0035] In other embodiments of the present disclosure, Figure 3As shown, the filling unit 3 may also include a third tin point group 6 arranged at the edge of the body 1 and arranged along the extension direction of the side of the body 1. The third tin point group 6 is extended along the side of the body 1 to reduce the gap on the side of the body 1, so that the connection between the metal shell 7 and the body 1 is tighter, ensuring the shielding effect of the metal shell 7. Specifically, the side of the body 1 may include a plurality of connecting edges connected in sequence, and the third tin point group 6 is at least adjacent to one connecting edge. In order to facilitate the arrangement of electrical components on the body 1, the connecting portion 2 on the body 1 is generally located on the side of the connecting edge. Therefore, the center position of the connecting edge is far from the connecting portion 2, and the gap is large, and the two sides of the connecting edge are close to the connecting portion 2, and the gap is small. Therefore, the height of the adjacent two tin points 32 in the plurality of tin points 32 in the third tin point group 6, the tin points 32 close to the two sides of the connecting edge are not greater than the height of the tin points 32 close to the center of the connecting edge, and the height of at least one tin point 32 close to the center of the connecting edge among the plurality of tin points 32 is greater than the height of the tin points 32 close to the two sides of the connecting edge.

[0036] Among them, there can also be multiple third tin point groups 6, and the multiple third tin point groups 6 can be spaced apart in the direction away from the connecting edge. In addition, the multiple tin points 32 of the spaced third tin point group 6 can be staggered and / or spaced apart in the direction perpendicular to the connecting edge adjacent to it to increase the density of the tin points 32, reduce the gap between the metal shell 7 and the main body 1, ensure the shielding effect of the metal shell 7, and reduce the electromagnetic interference to the main body 1.

[0037] The second aspect of the present disclosure provides a controller, including a metal shell 7 and the above-mentioned circuit board, the metal shell 7 is provided with a matching portion 8 corresponding to the connecting portion 2, and the fastener 9 can connect the circuit board and the metal shell 7 through the connecting portion 2 and the matching portion 8. It should be noted that the controller may also include a matching metal shell connected to the body 1, the metal shell 7 and the matching metal shell are respectively located on both sides of the body 1, and the controller of the present disclosure may be a vehicle domain controller. In addition, the controller has all the beneficial effects of the circuit board, which will not be repeated in this disclosure.

[0038] A third aspect of the present disclosure provides a vehicle including the above-mentioned controller, and the vehicle has all the beneficial effects of the above-mentioned controller, which will not be elaborated in the present disclosure.

[0039] In summary, the present disclosure exemplarily illustrates the process of matching the circuit board and the metal shell 7 .

[0040] The tin dots 32 arranged around a single connection part 2 on the main body 1 of the present disclosure can gradually increase in height in the direction away from the connection part 2; the tin dots 32 arranged between two adjacent connection parts 2 on the main body 1 can gradually decrease in height from the middle of the two connection parts 2 toward the two connection parts 2; and a plurality of tin dots 32 with different heights can also be arranged near the edge of the main body 1. The tin dots 32 with lower heights can fill smaller gaps, and the tin dots 32 with higher heights can fill larger gaps, that is, the tin dots 32 arranged on the main body 1 can offset the metal shell 7, so as to reduce the gap between the main body 1 and the metal shell 7, thereby improving the shielding performance of the metal shell 7, reducing or even avoiding external interference with the electronic and electrical modules on the main body 1, and ensuring the normal operation of the circuit board.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
