Instead, they are only examples of methods and devices consistent with some aspects of the utility model as detailed in the attached claims.

[0048] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here, for example, can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations 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 necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0049] At present, the all-in-one controller used in some new energy vehicle models integrates multiple different functional modules such as MCU (Motor Control Unit), OBC (On-Board Charger), DCDC (DC-DC converter), PDU (Power Distribution Unit), VCU (Vehicle Control Unit), etc. The amount of data for internal and external signal interaction is huge, so connectors with more than 100 pins are generally used for communication connection. Since the connector itself does not have a sealing structure, it is currently sealed with an overall wet glue when it is packaged with the shell. During assembly, the glue is still in liquid state. After assembly and curing, the controller shell, connector, and cover plate will be bonded, and the bonding strength is relatively large. Therefore, after curing, it needs to be destructively dismantled in order to repair or replace it, which is not convenient for disassembly and assembly, affecting the cost of using the vehicle. In addition, the above-mentioned wet glue packaging has high process requirements, is easily affected by the environment, and is not convenient for assembly and rework.

[0050] In view of the above problems existing in the prior art, the utility model provides a controller and a vehicle.

The connector is inserted in the notch, and the circuit board is provided in the housing cavity, so as to facilitate the exchange of internal and external information. The crimping piece is covered on the connector and detachably connected to the shell, and the peripheral side of the connector and the notch corresponding to it and the crimping piece are sealed by a sealing part. The cover body is detachably covered on the shell, and the cover body and the shell corresponding to the cover body and the crimping piece are sealed by a sealing piece. That is, the periphery of the connector is enclosed and sealed by cooperating with the crimping part and the notch, and a sealing part is arranged between the cover body, the shell and the crimping part, and the seal is compressed by the sealing part, thereby facilitating the disassembly and assembly between the cover body, the shell and the crimping part, so as to maintain the functional modules on the circuit board.

[0051] Hereinafter, exemplary application scenarios of the embodiments of the present utility model are introduced.

[0052] The controller provided by the utility model can be applied to new energy vehicles, hybrid vehicles, traditional fuel vehicles and mechanical equipment with controllers, wherein new energy vehicles and hybrid vehicles include light vehicles such as sedans, pickup trucks, multi-purpose vehicles (MPVs), and off-road vehicles (SUVs) with battery packs. By setting the above controller, when the controller fails, it can be easily disassembled and maintained to reduce the cost of using the vehicle.

[0053] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0054] First, refer to Figure 1-Figure 4 As shown, the controller provided in this embodiment includes a circuit assembly 100 and a housing assembly 200. The circuit assembly 100 includes a circuit board 110 and a plug-in connector 120 connected to the circuit board 110. The housing assembly 200 includes a housing 210, a crimping member 220, and a cover 230. The housing 210 has a receiving cavity 211. One side of the housing 210 has a notch 212, and the notch 212 is connected to the receiving cavity 211.

[0055] The plug connector 120 is inserted in the slot 212, and the circuit board 110 is located in the accommodating cavity 211. The crimping part 220 is covered on the plug connector 120 and is detachably connected to the housing 210. The peripheral side of the plug connector 120 and the corresponding slot 212 and the crimping part 220 are sealed by the sealing part 201. The cover 230 is detachably covered on the housing 210, and the cover 230 and the housing 210 corresponding to the cover 230 and the crimping part 220 are sealed by the sealing part 202.

[0056] In this embodiment, the circuit board 110 can be a PCB board, the connector 120 can be a plug with 100 pins or more, the plug can be one or multiple plugs arranged side by side, and the connector 120 can be connected to the circuit board 110 by welding, clamping, screwing, etc.

[0057] The shell 210 is used to install the circuit board 110 and the connector 120. The shell 210 has a housing 211 with an opening at the top. One side of the shell 210 has a slot 212 that matches a portion of the peripheral wall of the connector 120. The slot 212 is roughly U-shaped and is connected to the housing 211 so that the connector 120 can pass through the slot 212.

[0058] The plug-in connector 120 is inserted into the slot 212, and the circuit board 110 is installed in the accommodating cavity 211. Multiple functional modules can be integrated on the circuit board 110. The crimping connector 220 is used to fix the peripheral wall of the plug-in connector 120 that is not matched with the slot 212. It can be a plate-shaped, block-shaped structure, etc., and can be detachably connected to the housing 210 on both sides of the opening of the slot 212 by screwing, clamping, etc., so as to facilitate disassembly and assembly. The plug-in connector 120 is pressed tightly into the slot 212 by the crimping connector 220 to prevent loosening.

[0059] The sealing part 201 is used to seal the peripheral side of the plug connector 120 and the notch 212 and the crimping part 220. The sealing part 201 can be a sealant, a sealing ring, a sealing pad, etc. It should be noted that if the sealing part 201 is a sealant, in some cases, the functional module on the circuit board 110 can be repaired without removing the sealant there. In other cases, even if the sealant there is destructively removed, only a small area of ​​the sealant needs to be removed and sealed, and the damaged sealing surface is greatly reduced.

[0060] The cover body 230 is used to cover the shell 210 to seal the top opening of the accommodating cavity 211. The cover body 230 can be detachably connected to the side of the shell 210 by screwing, snapping, etc., which is convenient for disassembly and assembly. A sealing member 202 is also provided between the cover body 230, the shell 210 and the crimping member 220.

[0061] One side of the seal 202 can be pre-fixed on the side of the cover 230 facing the housing 210 and the crimping member 220, and the other side of the seal 202 is sealed by abutting and pressing against the housing 210 and the crimping member 220. Alternatively, one side of the seal 202 is pressed and sealed against the side of the cover 230 facing the housing 210 and the crimping member 220, and the other side of the seal 202 is also pressed and sealed against the housing 210 and the crimping member 220, so that when disassembling, the integrity of the seal 202 can be guaranteed without damaging the sealing surface.

[0062] It is understandable that the controller provided in this embodiment uses the crimping piece 220 to cooperate with the notch 212 to enclose and seal the peripheral side of the plug-in component 120, thereby facilitating the disassembly and assembly of the plug-in component 120. A sealing piece 202 is provided between the cover 230, the housing 210, and the crimping piece 220, and the sealing piece 202 is used to compress and seal, thereby facilitating the disassembly and maintenance of the cover 230, the housing 210, and the crimping piece 220.

[0063] It should be noted that a threading hole may be left on the housing 210 to facilitate the connection of the cable to the circuit board 110. Of course, the cable and the threading hole may be sealed by wet glue bonding or by a sealing ring.

[0064] In a possible design, the peripheral side of the plug connector 120 has a first sealing surface 2011, and the inner wall of the notch 212 has a second sealing surface 2012. The side of the crimping piece 220 facing the plug connector 120 has a third sealing surface 2013, and the first sealing surface 2011, the second sealing surface 2012 and the third sealing surface 2013 are bonded and cured by a first adhesive to form a sealing portion 201.

[0065] Specifically, Figure 4 As shown, the first adhesive can be a sealing wet glue, such as SLD-8791 series adhesive sealing silica gel, etc. The sealing wet glue can be first applied to the first sealing surface 2011, or the sealing wet glue can be applied to the second sealing surface 2012, or the sealing wet glue can be applied to the third sealing surface 2013, and then the plug-in 120 is installed in the notch 212, and the crimping piece 220 is connected to the housing 210 on both sides of the notch 212. Finally, the sealing wet glue is cured to bond the plug-in 120 to the gap between the notch 212 and the crimping piece 220 to seal, and the sealing performance is good. The type of the sealing wet glue can be selected according to actual needs, and is not specifically limited in this embodiment.

[0066] It should be noted that even if the circuit board 110 and the connector 120 need to be removed from the notch 212, only this part of the sealing wet glue needs to be destroyed. The damaged sealing surface is small, which is convenient for re-applying glue and has a relatively low cost.

[0067] Furthermore, in this embodiment, at least one of the connector 120 , the notch 212 and the crimping member 220 has a first receiving groove 121 , and the first receiving groove 121 is used to receive the first adhesive on the first sealing surface 2011 , the second sealing surface 2012 or the third sealing surface 2013 .

[0068] For example, Figure 4 As shown, a first receiving groove 121 is provided on the peripheral side of the connector 120 , and the sealing wet glue can be applied to a specified position on the first sealing surface 2011 . On the other hand, the first receiving groove 121 can also cooperate with the notch 212 to limit the connector 120 .

[0069] Of course, the first receiving groove 121 can also be opened on the notch 212 and the side of the crimping piece 220 facing the plug-in piece 120, which is not shown in the figure, and the sealing wet glue can be applied to a designated position on the second sealing surface 2012 or the third sealing surface 2013. The specific width of the first receiving groove 121 can be determined according to actual needs and is not specifically limited in this embodiment.

[0070] In some embodiments, the sealing member 202 is a sealing gasket formed by bonding and curing the second adhesive on the side of the cover 230 facing the housing 210 .

[0071] Specifically, not shown in the figure, the second adhesive can also be a sealing wet glue, such as SLD-8791 series adhesive sealing silicone rubber.

[0072] The wet sealant can be first applied to the sealing surface of the cover 230 facing the shell 210, so that the wet sealant is bonded to the cover 230 and cured to form a sealing gasket. The sealing gasket after pre-curing is in a soft rubber state. The cover 230 is then packaged on the shell 210. The cured sealing gasket on the cover 230 is compressed and sealed with the shell 210 and the crimping piece 220, and there is no bonding effect. The sealing gasket does not need to be destroyed during disassembly. The type of wet sealant can be selected according to actual needs, and is not specifically limited in this embodiment.

[0073] In some other embodiments, the sealing member 202 is a sealing ring, one side of which is pressed and sealed with the housing 210 and the crimping member 220 , and the other side of which is pressed and sealed with the cover 230 .

[0074] Specifically, Figure 4 As shown, the sealing ring can be made of rubber, silicone, etc. In this way, the cover 230 is tightly sealed with the housing 210 and the crimping member 220 through the sealing ring, which is more convenient for disassembly and assembly without damaging the sealing ring. The specific model and installation position of the sealing ring are not specifically limited in this embodiment.

[0075] Further, in this embodiment, the housing 210 and the crimping member 220 are provided with a second receiving groove 213 for receiving the sealing member 202 on one side facing the cover 230. And / or, the cover 230 is provided with a second receiving groove 213 for receiving the sealing member 202 on one side facing the housing 210 and the crimping member 220.

[0076] Specifically, Figure 2 , Figure 3 , Figure 4 As shown, a second receiving groove 213 is opened on the side of the housing 210 and the crimping member 220 facing the cover body 230, so that the sealing wet glue can be quickly applied to the specified position on the housing 210 and the crimping member 220, or it is convenient to position the sealing ring.

[0077] Of course, the second accommodating groove 213 can also be opened on the sealing surface of the cover body 230 facing the shell 210 and the crimping piece 220, which is not shown in the figure. The specific width of the second accommodating groove 213 can be determined according to actual needs and is not specifically limited in this embodiment.

[0078] In order to facilitate assembly and disassembly between the crimping member 220 and the housing 210 , in this embodiment, the housing assembly 200 further includes at least two first fasteners 240 , and the crimping member 220 is respectively connected to the housing 210 at the notch 212 through the two first fasteners 240 .

[0079] For example, Figure 2 , Figure 4 As shown, the first fastener 240 can be a fastening screw, a fastening bolt, etc. The two first fasteners 240 pass through the two sides of the crimping member 220 respectively and are connected to the housing 210 on both sides of the opening of the slot 212 respectively.

[0080] Of course, the first fastener 240 may also be replaced by other components with fastening functions, such as rivets, etc. Therefore, the specific type, quantity, etc. of the first fastener 240 are not specifically limited in this embodiment.

[0081] In order to facilitate the disassembly and assembly between the shell 210 and the cover body 230, in this embodiment, the shell assembly 200 also includes a plurality of second fasteners 250, the cover body 230 is connected to the shell 210 through the plurality of second fasteners 250, and the plurality of second fasteners 250 are arranged at intervals on the peripheral sides of the shell 210 and the cover body 230.

[0082] For example, Figure 1 , Figure 2 , Figure 4 As shown, the second fastener 250 may also be a fastening screw, a fastening bolt, etc., and a plurality of second fasteners 250 respectively pass through the peripheral side of the cover body 230 and are respectively connected to the peripheral side of the housing 210. Alternatively, a plurality of second fasteners 250 respectively pass through the peripheral side of the housing 210 and are respectively connected to the peripheral side of the cover body 230, which facilitates disassembly and assembly while also ensuring the balance of the connection force between the housing 210 and the cover body 230.

[0083] Of course, the second fastener 250 may also be replaced by other components with fastening functions, such as rivets, etc. Therefore, the specific type, quantity, etc. of the second fastener 250 are not specifically limited in this embodiment.

[0084] Furthermore, in this embodiment, the housing 210 has a partial flange 214 on one side facing the cover 230, and the second fastener 250 is connected to the partial flange 214. Figure 2 As shown, the housing 210 has a partial flange 214 turned outward at the periphery of the opening of the accommodating cavity 211, that is, there is no flange at the notch 212, and the flange is used to increase the contact surface with the cover 230, thereby ensuring the reliability of the connection. The specific size of the partial flange 214 can be determined according to actual needs and is not specifically limited in this embodiment.

[0085] It should be noted that the end surface of the crimping member 220 and the part of the flange 214 facing the cover body 230 are flush. Figure 2As shown, after the crimping piece 220 is installed on the shell 210, the side of the crimping piece 220 and part of the flange 214 facing the cover body 230 is a flat surface. Correspondingly, the contact surface on the side of the cover body 230 facing the shell 210 can be made flat, which is convenient for manufacturing, assembly, etc.
