[0071] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0072] This application proposes a controller, Figures 1 to 9 As shown in the drawings, the Z direction in the drawings is a first direction, and the first direction Z is used in the following description.

[0073] See also Figure 1 In some embodiments of the present application, the controller includes a shell 1, the shell 1 includes a shell body 10, the shell body 10 includes a first sub-shell 101 and a second sub-shell 102, the second sub-shell 102 is integrated on the first sub-shell 101, it can be understood that the second sub-shell 102 is integrated on the first sub-shell 101 means that the second sub-shell 102 is fixedly connected to the first sub-shell 101, or the second sub-shell 102 is integrally formed with the first sub-shell 101; wherein, the first sub-shell 101 is the controller shell in the related art, and the second sub-shell 102 is the connector shell in the related art, that is, in the embodiments of the present application, the controller shell and the connector shell in the related art are integrated together to reduce the production difficulty and manufacturing cost of the controller.

[0074] In some embodiments of the present application, the housing body 10 is formed by injection molding.

[0075] In some embodiments of the present application, the controller also includes an electronic component 20, which includes a circuit board 2 and a connecting terminal 3. The circuit board 2 is accommodated in a first sub-shell 101, one end of the connecting terminal 3 is connected to the circuit board 2 and accommodated in the first sub-shell 101, and the other end of the connecting terminal 3 away from the circuit board 2 is accommodated in a second sub-shell 102; wherein a part of the connecting terminal 3 accommodated in the second sub-shell 102 and the second sub-shell 102 together constitute a connector in the related technology, and the circuit board 2 is connected to an external device through the connecting terminal 3 to collect vehicle body acceleration and signal changes of the inertial measurement unit.

[0076] In some embodiments of the present application, the connection terminal 3 and the second sub-housing 102 are clearance-matched, that is, the connection terminal 3 and the second sub-housing 102 are assembled separately, thereby forming a connector in the related art.

[0077] In the technical solution of the present application, the first sub-shell 101 and the second sub-shell 102 are integrated, that is, the connector shell and the controller shell in the related art are integrated together, and then the circuit board 2 and a part of the connecting terminal 3 are respectively arranged in the first sub-shell 101 and the second sub-shell 102, so that a part of the connecting terminal 3 is combined with the second sub-shell 102 to form the connector in the related art; that is, in the embodiment of the present application, by connecting the circuit board 2 and the connecting terminal 3 and assembling them into the shell body 10, the controller with the connector in the related art can be directly combined to form, and there is no need to separately arrange the connector in the related art on the shell body 10 of the present application, so as to simplify the production difficulty of the controller in the embodiment of the present application and reduce the manufacturing cost of the controller.

[0078] It is understandable that the connector in the related art is integrally formed and needs to be fixed to the controller housing by bolts or injection molding when assembled to the controller housing. However, in the present application, the connector can be formed when the circuit board 2 and the connecting terminal 3 are assembled with the housing 1, thereby reducing the production difficulty and manufacturing cost of the controller.

[0079] See also Figure 2 In some embodiments of the present application, a first cavity 1A and a second cavity 1B are respectively disposed on both sides of the housing body 10, the first cavity 1A is located on the first sub-housing 101, and the second cavity 1B is located on the second sub-housing 102; wherein the first cavity 1A and the second cavity 1B are interconnected, the circuit board 2 is located in the first cavity 1A, a part of the connection terminal 3 is located in the first cavity 1A, and the other part is located in the second cavity 1B. Such a configuration reduces the possibility of liquid entering the first cavity 1A from the second cavity 1B.

[0080] It should be noted that, since the controller is installed in the central channel of the vehicle and is located below the air conditioning duct, the air conditioning duct is easily offset during installation, resulting in air leakage, which puts the controller in a low temperature and high humidity environment, so that liquid is easy to drip on the shell body 10, and then accumulate on the shell body 10. In the related art, the position of the connector is located on the side of the controller housing, and it is not easy to drain when the liquid is deposited on the controller housing, making the controller easy to get water in. The second cavity 1B in the present application is located at the top of the shell body 10, thereby reducing the possibility of water intrusion into the controller due to liquid deposition.

[0081] In some embodiments of the present application, the female end wiring harness can be connected to the connection terminal 3 located in the second cavity 1B to achieve the connection between the controller and the external device.

[0082] In addition, the first cavity 1A and the second cavity 1B may be connected to each other in the first direction Z; or may be connected to each other in any direction intersecting with the first direction Z.

[0083] Similarly, the connection point between the first cavity 1A and the second cavity 1B can be located on the first sub-shell 101 or on the second sub-shell 102; it can also be set at the connection position between the first sub-shell 101 and the second sub-shell 102; there is no limitation here.

[0084] In some embodiments of the present application, the first cavity 1A and the second cavity 1B are connected to each other in the first direction Z.

[0085] See also Figures 2 to 3 In some embodiments of the present application, an opening 1C is provided on the second sub-shell 102, and the opening 1C connects the first cavity 1A and the second cavity 1B; wherein the connecting terminal 3 and the circuit board 2 are assembled together into the first cavity 1A, and a part of the connecting terminal 3 is inserted into the second cavity 1B from the opening 1C after the circuit board is assembled in place, so as to cooperate with the second sub-shell 102 to form a connector in the related art.

[0086] In some embodiments of the present application, at least a portion of the second sub-shell 102 is recessed on a side of the housing 1 away from the circuit board 2 in the first direction Z. The second sub-shell 102 includes a side wall 1021 and a bottom wall 1022 that enclose and form a second cavity 1B.

[0087] See also Figure 2 In some embodiments of the present application, in the first direction Z, the first cavity 1A, the opening 1C and the second cavity 1B are connected in sequence; in this embodiment, the opening 1C is arranged on the bottom wall 1022 of the second sub-shell 102, and when the female-end wiring harness is installed in the second cavity 1B, the connecting part of the female-end wiring harness and the connecting terminal 3 is oriented toward the opening 1C in the first direction Z and assembled with the connecting terminal 3.

[0088] It is understandable that the opening 1C can also be set on the side wall of the second sub-shell 102; on this basis, when the female end wiring harness is installed in the second cavity 1B, the connection part between the female end wiring harness and the connecting terminal 3 faces the side wall of the second sub-shell 102.

[0089] In some embodiments of the present application, the size of the opening 1C is smaller than the size of the second cavity 1B; that is, it is configured such that a sink 16 is formed at the connecting position of the opening 1C and the second cavity 1B, and the sink 16 is arranged on the bottom wall 1022. On the one hand, when the female-end wiring harness is inserted into the second cavity 1B, it will be limited by the sink 16 to avoid damage to the female-end wiring harness or the connecting terminal 3 due to excessive force when the female-end wiring harness is connected to the connecting terminal 3 in the first direction Z; on the other hand, it also makes the protection of the connecting terminal 3 by the second sub-shell 102 more reliable.

[0090] In some embodiments of the present application, the second cavity 1B passes through the second sub-shell 102 in the first direction Z; in the first direction Z, one of the two opposite ends of the second cavity 1B is provided with an opening 1C for insertion of the connecting terminal 3, and the other end is used for insertion of the female end wiring harness; the first direction Z is the height direction, that is, after the connecting terminal 3 is inserted into the second cavity 1B, it can be directly exposed at the other end of the second cavity 1B, so that the plug-in direction of the wiring harness is the first direction Z, which makes it easy to plug in the female end wiring harness; at the same time, after the female end wiring harness and the connecting terminal 3 are assembled, they are located within the covering range of the side wall 1021 of the second sub-shell 102 to provide protection for the female end wiring harness and the connecting terminal 3.

[0091] In some embodiments of the present application, a stop portion 4 is provided on the side of the shell body 10 facing away from the circuit board 2, and the stop portion 4 is used to block the liquid from entering the second cavity 1B, that is, the stop portion can limit the liquid falling on the side of the shell facing away from the circuit board 2 from entering the second cavity 1B from the position where the stop portion 4 is provided, so as to improve the waterproof ability of the controller.

[0092] See also Figure 3 to Figure 4 In some embodiments of the present application, a stopper 4 is provided on the side of the shell body 10 away from the circuit board 2, and the stopper 4 is provided around the second cavity 1B; by providing the stopper 4, the stopper 4 has a certain size in the first direction Z and is provided around the second cavity 1B, thereby limiting the liquid falling on the side of the shell away from the circuit board 2 from entering the second cavity 1B, so as to improve the waterproof ability of the controller.

[0093] In some embodiments of the present application, the housing body 10 is provided with a stopper 4 on the side facing away from the circuit board 2, and at least a portion of the stopper 4 is located on one side of the second cavity 1B. That is, in this embodiment, by providing the stopper 4 on the peripheral portion of the second cavity 1B, the liquid falling on the side of the housing facing away from the circuit board 2 is restricted from entering the second cavity 1B from the position where the stopper 4 is provided, so as to improve the waterproof capability of the controller.

[0094] The stopper 4 may be connected to the first sub-shell 101 or the second sub-shell 102; the stopper 4 may also be connected to both the first sub-shell 101 and the second sub-shell 102. In one embodiment of the present application, the stopper 4 and the housing body 10 are integrally injection molded; in another embodiment of the present application, the stopper 4 and the housing body 10 are separately molded and assembled with each other.

[0095] In some embodiments of the present application, at least one first guide groove 5 is provided on the side of the shell body 10 facing away from the circuit board 2. The first guide groove 5 is located on one side of the second sub-shell 102 and extends from the second sub-shell 102 to the edge of the shell body 10. The first guide groove 5 is used to guide the liquid to flow away from the shell body 10; wherein, the setting of the first guide groove 5 can prevent the liquid from accumulating on the shell body 10 to cause liquid deposition.

[0096] It should be supplemented that the first guide groove 5 can guide the liquid located on one side of the second sub-shell 102 out of the housing body 10 to prevent the liquid from being deposited in the second cavity 1B.

[0097] See also Figure 5 In some embodiments of the present application, the shell body 10 has a first surface 11A, and the first surface 11A is located on the side of the shell body 10 away from the circuit board 2; the first surface 11A is inclined; that is, in this embodiment, the first surface 11A is located at the top of the shell body 10, and the inclined first surface 11A can speed up the speed at which the liquid flows down from the shell.

[0098] In some embodiments of the present application, the shell body 10 is recessed from the first surface 11A to the interior of the shell body 10 to form at least one first guide groove 5 to guide the liquid to flow away from the shell body 10; wherein the first guide groove 5 is provided on the first surface 11A, so that the first surface 11A can guide the liquid to enter the first guide groove 5 and then flow out of the first guide groove 5, thereby avoiding the accumulation of liquid on the shell body 10 to improve the waterproof ability of the controller.

[0099] In some embodiments of the present application, the controller also includes a waterproof cover 7, which is arranged on the shell body 10 and covers the side of the second sub-shell 102 away from the circuit board 2, that is, the waterproof cover 7 can cover the connecting terminal 3, thereby preventing liquid from contacting the connecting terminal 3 and causing damage to the connecting terminal 3.

[0101] In some embodiments of the present application, a stopper 4 is arranged around the second cavity 1B to prevent liquid from flowing into the second cavity 1B. When the controller is installed on the vehicle, the female wiring harness is plugged into the second cavity 1B, and then the waterproof cover 7 is installed on the stopper 4 to improve the waterproof ability of the controller.

[0102] In some embodiments of the present application, the waterproof cover 7 and the stopper 4 are interference fit to prevent liquid from entering the second cavity 1B through the gap between the waterproof cover 7 and the stopper 4, so as to further improve the waterproof capability of the controller.

[0103] There is no limitation on the connection method between the waterproof cover 7 and the stopper 4. In one embodiment, the waterproof cover 7 is mounted on the stopper 4. In another embodiment, the waterproof cover 7 can be slidably mounted on the stopper 4 to open or seal the second cavity 1B. In another embodiment, the waterproof cover 7 can be flipped on the stopper 4 to open or seal the second cavity 1B.

[0106] There are two first guide grooves 5 , and the two first guide grooves 5 are respectively located at two opposite ends of the stopper 4 .

[0107] In addition, a portion of the stopper 4 is disposed near the periphery of the housing body 10 , so that the liquid can flow down from the top of the housing body 10 along the stopper 4 under the influence of gravity to avoid accumulation of liquid on the top of the housing body 10 .

[0108] See also Figures 4 to 5 In some embodiments of the present application, the housing 1 also includes a bottom plate 11, which is fixedly connected to the housing body 10; that is, in this embodiment, the bottom plate 11 and the housing body 10 jointly protect the circuit board, and the bottom plate 11 and the housing body 10 jointly seal the circuit board 2.

[0115] In some embodiments of the present application, the first guide groove 5 and the second guide groove 6 are staggered in the first direction Z, that is, part of the liquid on the top of the shell body 10 can flow directly away from the controller through the first guide groove 5, and the other part flows into the second guide groove 6 of the bottom plate 11 and then flows away from the controller.

[0116] It is understandable that the liquid on the bottom plate 11 can also flow away from the controller through the second guide groove 6 .

[0117] In some embodiments of the present application, the controller further includes a limiting structure 8, which is used to limit the movement of the circuit board 2 in the housing 1; that is, the limiting structure 8 can fix the circuit board 2 in the controller.

[0118] In some embodiments of the present application, the limiting structure 8 is located in the first cavity 1A to fix the circuit board 2 .

[0119] In one embodiment of the present application, a portion of the limiting structure 8 is located inside the circuit board 2 and cooperates with the circuit board 2, thereby limiting the movement of the circuit board 2; in another embodiment of the present application, a portion of the limiting structure 8 is located on one side of the circuit board 2 and cooperates with the circuit board 2, thereby limiting the movement of the circuit board 2; in yet another embodiment of the present application, a portion of the limiting structure 8 is located on one side of the circuit board 2 and the other portion is located inside the circuit board 2, so as to cooperate with the circuit board 2, thereby limiting the movement of the circuit board 2.

[0120] See also Figure 6 and Figure 8 In some embodiments of the present application, the limiting structure 8 includes at least one limiting member 81, which is arranged on the housing 1; a through hole 9 is also provided through the circuit board 2, and the limiting member 81 is provided through the through hole 9; in this embodiment, the limiting member 81 is provided to limit the position of the circuit board 2 in the controller.

[0121] It can be understood that since the circuit board 2 is also connected to the connecting terminal 3, when the circuit board 2 is assembled into the first cavity 1A, the limit member 81 is inserted into the via hole 9 on the circuit board 2, thereby ensuring the accuracy of the alignment of the connecting terminal 3 and the opening 1C in the first direction Z, so as to avoid the connecting terminal 3 and the shell body 10 from abutting against each other during assembly, thereby causing damage or tilting of the connecting terminal 3.

[0122] The stopper 81 can be disposed on the housing body 10 or on the bottom plate 11; this is not limited here. In some embodiments of the present application, the stopper 81 is disposed on the housing body 10. This is because the circuit board 2 is assembled with the housing body 10 first during the assembly of the controller to ensure the accuracy of the alignment of the connection terminal 3 and the opening 1C in the first direction Z.

[0123] In some embodiments of the present application, two limiting members 81 are provided and the two limiting members 81 are spaced apart from each other; such a configuration is used to prevent the circuit board 2 from rotating when it is assembled onto the housing body 10 .

[0124] In some embodiments of the present application, the via hole 9 of the circuit board 2 is interference fit with at least a portion of the limit member 81; this configuration is used to reduce the gap between the via hole 9 of the circuit board 2 and the limit member 81, thereby ensuring that the circuit board 2 does not move when assembled to the shell body 10, thereby ensuring the accuracy of the alignment of the connecting terminal 3 and the opening 1C in the first direction Z.

[0125] It can be understood that, due to the interference fit between the through hole 9 of the circuit board 2 and at least a portion of the limit member 81, when the circuit board 2 is assembled to the shell body 10, the circuit board 2 will not easily fall off the shell body 10 when subjected to external force, so that the operator or the operating tool can further assemble the controller.

[0126] In some embodiments of the present application, the size of the first end of the limit member 81 connected to the shell 1 is larger than the size of the second end of the limit member 81 away from the shell 1; this arrangement facilitates the assembly of the circuit board 2 to the shell body 10 or the bottom plate 11 in the first direction Z.

[0127] The through hole 9 of the circuit board 2 is interference-fitted with an end of the limiting member 81 close to the housing 1 .

[0128] In some embodiments of the present application, the limit member 81 includes a main body 811 and at least one convex rib 812, the main body 811 is arranged on the housing 1; the convex rib 812 is located on the circumferential side of the main body 811; the size of the main body 811 and / or the convex rib 812 gradually decreases in the direction from the first end to the second end; in this embodiment, by setting the size change of the main body 811 and / or the convex rib 812, the circuit board 2 is interference fit with the limit member 81 when assembled into the controller.

[0129] In some embodiments of the present application, the size of the main body 811 and / or the rib 812 in the first direction Z gradually decreases, that is, the direction from the first end to the second end of the limit member 81 is the first direction Z. By setting the size change of the main body 811 and / or the rib 812, the circuit board 2 is interference fit with the limit member 81 when assembled into the controller in the first direction Z.

[0130] In some embodiments of the present application, the main body 811 is arranged on the shell body 10, and the size of the end of the main body 811 away from the shell body 10 is smaller than the size of the end of the main body 811 close to the shell body 10; at the same time, the size of the rib 812 gradually decreases in the direction away from the shell body 10, thereby facilitating the assembly of the circuit board 2 onto the limit member 81 until the via 9 on the circuit board 2 is interference fit with the limit member 81.

[0131] In some embodiments of the present application, the limiting structure 8 includes at least one abutment member, which is provided on the outer shell 1, and the end of the abutment member facing away from the outer shell 1 is in contact with the circuit board 2; that is, by providing the abutment member, the circuit board 2 is in close contact with the abutment member after being assembled to the outer shell 1, thereby preventing the circuit board 2 from being deformed due to the influence of the assembly gap after assembly, thereby causing stress damage to the circuit board 2.

[0132] The abutting member can be disposed on the housing body 10 or the bottom plate 11 , which is not limited herein.

[0133] In some embodiments of the present application, the abutment member includes a first abutment member 82, which is arranged on the outer shell 1; wherein, the end of the first abutment member 82 facing away from the outer shell 1 is in contact with the circuit board 2; in this embodiment, by setting the first abutment member 82 to be in contact with the circuit board 2 in the first direction Z, deformation of the circuit board 2 due to the influence of the assembly gap after assembly is avoided, thereby causing stress damage to the circuit board 2; at the same time, the setting of the first abutment member 82 can limit the circuit board 2 to the corresponding installation position in the first direction Z.

[0134] In some embodiments of the present application, the first abutment member 82 is disposed on the housing body 10 , thereby limiting the movement of the circuit board 2 in the first direction Z toward the housing body 10 .

[0135] The number of the first abutment member 82 is one or more. Figure 8 In some embodiments of the present application, four first abutting members 82 are provided and are all mounted on the housing body 10 .

[0136] In some embodiments of the present application, the abutment member also includes at least one second abutment member 83, which is arranged on the base plate 11, and one end of the second abutment member 83 facing away from the base plate 11 is in contact with the circuit board 2; wherein the second abutment member 83 can support the circuit board 2 in the first direction Z and limit the circuit board 2 to the corresponding installation position, and the second abutment member 83 can also limit the movement of the circuit board 2 in the first direction Z toward the base plate 11.

The first abutment member 82 and the second abutment member 83 respectively abut against two sides of the circuit board 2 in the first direction Z to jointly limit the movement of the circuit board 2 in the first direction Z.

[0138] In some embodiments of the present application, the first abutment member 82 and the second abutment member 83 are relatively arranged in the first direction Z; this arrangement is to avoid the situation where the position where the circuit board 2 is abutted by the first abutment member 82 or the second abutment member 83 is only subjected to a force in a single direction in the first direction Z, causing the circuit board 2 to be deformed, thereby causing the circuit board 2 to be deformed.

[0139] In some embodiments of the present application, at least one through groove 12 is provided through the circuit board 2, and the controller includes at least one fastener 13, which passes through the first abutment 82, the through groove 12 and the second abutment 83 in sequence, so that the shell body 10, the bottom plate 11 and the circuit board 2 are relatively fixed; in this embodiment, the first abutment 82, the circuit board 2 and the second abutment 83 are connected by the fastener 13 to realize the fixed assembly between the shell body 10 and the bottom plate 11, and at the same time, the fixed assembly between the circuit board 2 and the shell 1 is also realized.

[0140] In some embodiments of the present application, the fastener 13 is a screw, which passes through the second abutment 83 and the groove 12 in sequence from the side of the bottom plate 11 away from the shell body 10 and is screwed to the first abutment 82 to achieve fixed assembly between the shell body 10 and the bottom plate 11 and fixed assembly between the circuit board 2 and the shell 1.

[0141] In some embodiments of the present application, the limiting structure 8 also includes at least one third abutment member 84, which is arranged on the shell body 10 and close to the opening 1C; wherein, the end of the third abutment member 84 facing away from the shell body 10 is in contact with the circuit board 2; wherein, when the female end wiring harness is separated from the connecting terminal 3, a force away from the bottom plate 11 in the first direction Z is applied to the circuit board 2 through the connecting terminal 3, and the setting of the third abutment member 84 can abut against the part of the circuit board 2 opposite to the opening 1C in the first direction Z, so as to avoid deformation of the circuit board 2 when the female end wiring harness is separated from the connecting terminal 3.

[0142] In some embodiments of the present application, a plurality of third abutment members 84 are provided; the plurality of third abutment members 84 are arranged around the opening 1C; such arrangement is used to increase the contact area between the circuit board 2 and the third abutment members 84, thereby preventing the circuit board 2 from deforming when the female end wiring harness is separated from the connecting terminal 3.

[0143] In some embodiments of the present application, a plurality of third abutment members 84 are located between two limit members 81; wherein, the two limit members 81 are respectively located on both sides of the connection position between the circuit board 2 and the connecting terminal 3, so as to better position the installation of the circuit board 2 in the housing 1, and avoid the connecting terminal 3 from abutting against the housing body 10 during assembly of the controller, thereby causing damage or tilting of the connecting terminal 3.

[0144] In some embodiments of the present application, four first abutment members 82 and two limiting members 81 are spaced apart along the periphery of the circuit board 2 to ensure that the circuit board 2 is firmly fixed in the housing 1 and to prevent the circuit board 2 from being damaged by stress after assembly.

[0150] In some embodiments of the present application, the second abutment member 83 is located in the enclosed space of the first rib 14; this configuration is due to the fact that at least a portion of the second abutment member 83 is opposite to the circuit board 2 in the first direction Z, which ensures that the periphery of the circuit board 2 will not exceed the first rib 14, thereby ensuring waterproof protection of the circuit board 2.

[0151] In some embodiments of the present application, the second guide groove 6 is located on one side of the first rib 14 and is arranged close to the first rib 14, so that the liquid located on the peripheral side of the first rib 14 can flow into the second guide groove 6 to avoid liquid accumulation on the peripheral side of the second guide groove 6.

[0152] In some embodiments of the present application, one end of the second abutment 83 facing the circuit board 2 and one end of the fourth abutment 85 facing the circuit board 2 are located on the same horizontal plane.
