[0033] The following is for reference. Figures 1-6 The description of the housing structure 100 of the controller according to an embodiment of the present invention allows at least two housings 1 to form a multi-layer structure along the inner and outer directions at the insertion mating points of the insertion groove 12 and the insertion protrusion 11. This lengthens the path for particles such as salt spray to enter the housing 1, reducing the possibility of salt spray particles entering the housing 1. Furthermore, a first sealing structure 2 is provided at the insertion mating points of the insertion groove 12 and the insertion protrusion 11, which further reduces the possibility of salt spray particles entering the housing 1 through sealing. This effectively reduces corrosion of the housing 1, internal PCB boards, and other electronic components, thereby improving the corrosion resistance of the controller housing structure 100 and extending the service life of the controller.

[0034] like Figures 1-6 As shown, the housing structure 100 of the controller according to one embodiment of the present invention includes at least two housings 1.

[0035] At least two housings 1 are connected sequentially along a first direction. One of the two adjacent housings 1 is provided with a plug-in protrusion 11 and the other housing 1 is provided with a plug-in groove 12. The plug-in protrusion 11 and the plug-in groove 12 are plugged into each other. That is to say, in two adjacent housings 1, one can be provided with a plug-in protrusion 11 and the other with a plug-in groove 12, or one can be provided with a plug-in groove 12 and the other with a plug-in protrusion 11. Both of these arrangements can achieve the connection of the two adjacent housings 1 through the plug-in engagement of the plug-in protrusion 11 and the plug-in groove 12. Moreover, the arrangement methods are diverse and can be flexibly selected.

[0036] Specifically, the insertion direction of the insertion protrusion 11 and the insertion groove 12 is consistent with the connection direction of at least two housings 1. That is, the insertion protrusion 11 and the insertion groove 12 can be inserted and engaged along the first direction. In this way, when at least two housings 1 are close to each other along the first direction, the insertion protrusion 11 and the insertion groove 12 can be inserted and connected, realizing the insertion connection of at least two housings 1. After the at least two housings 1 are inserted, they can also be detachably connected by multiple bolts or other fasteners, which can improve the connection strength between the at least two housings 1, thereby improving the overall strength of the controller housing structure 100, so as to ensure the reliability and stability of the controller operation. Its connection method is simple, easy to install, and facilitates subsequent disassembly and maintenance, reducing maintenance costs.

[0037] Among them, shell 1 can be two, three, four, etc.

[0038] It should be noted that the first direction can be the vertical direction or the horizontal direction. In this embodiment, the first direction is described as the vertical direction, that is, at least two shells 1 are connected in sequence along the vertical direction, and the insertion protrusion 11 and the insertion groove 12 are inserted and engaged along the vertical direction.

[0039] The insertion groove 12 and the insertion protrusion 11 are provided with a first sealing structure 2, which is made of an elastic material.

[0040] Specifically, the first sealing structure 2 has a sealing function. Since there will be a gap between the insertion groove 12 and the insertion protrusion 11, placing the first sealing structure 2 at the insertion point of the insertion groove 12 and the insertion protrusion 11 can seal this connection. The first sealing structure 2 can be made of rubber or other elastic materials, giving it good elasticity. This elasticity allows the insertion point of the insertion groove 12 and the insertion protrusion 11 to be reliably pressed together, improving the sealing effect and effectively reducing the possibility of external particles entering.

[0041] It should be noted that the controller housing 100 houses various electronic components, enabling the controller to perform control and monitoring functions. The controller housing 100 protects these internal electronic components and must meet an IP5K2 protection rating, providing some dust and water resistance. Especially in stringent salt spray tests, where the housing 1 and internal PCB board typically suffer corrosion and functional impairment, the controller housing 100 in this embodiment, through a plug-in connection, increases the path for salt spray particles to enter the housing 100. Furthermore, the sealing effect of the first sealing structure 2 further reduces the likelihood of salt spray particles entering.

[0042] According to the embodiment of the present invention, the housing structure 100 of the controller is provided with at least two housings 1 connected by insertion protrusions 11 and insertion grooves 12. This allows the at least two housings 1 to form a multi-layer structure along the inner and outer directions at the insertion mating points of the insertion grooves 12 and insertion protrusions 11, which lengthens the path for salt spray and other particles to enter the housing 1 and reduces the possibility of salt spray particles entering the housing 1. Furthermore, a first sealing structure 2 is provided at the insertion mating point of the insertion grooves 12 and insertion protrusions 11. Through the sealing effect, the possibility of salt spray particles entering the housing 1 is further reduced, which can effectively reduce the corrosion of the housing 1, internal PCB boards and other electronic components, and improve the corrosion resistance of the controller housing structure 100. This enhances the adaptability of the controller housing structure 100, extends the service life of the controller, and has a simple structure and good performance.

[0043] In some embodiments, there are three housings 1, namely a first housing 13, a second housing 14 and a third housing 15. The first housing 13, the second housing 14 and the third housing 15 together define an installation cavity. A first sealing structure 2 is provided between the first housing 13 and the second housing 14 and between the second housing 14 and the third housing 15.

[0044] Specifically, such as Figure 1As shown, the controller housing structure 100 is divided into three parts: a first housing 13, a second housing 14, and a third housing 15. The first housing 13, the second housing 14, and the third housing 15 are connected sequentially along the first direction and together define a mounting cavity for mounting electronic components. The electronic components can be PCB boards, chips, resistors, etc. Mounting multiple electronic components in the mounting cavity can protect multiple electronic components and ensure the reliability and stability of the controller operation.

[0045] In the actual design, the first housing 13 and the second housing 14 can be connected by a plug-in protrusion 11 and a plug-in groove 12, and a first sealing structure 2 is provided between the first housing 13 and the second housing 14 to ensure the sealing of the connection between the first housing 13 and the second housing 14, thereby reducing the possibility of external particles such as salt spray entering the mounting cavity from the connection between the first housing 13 and the second housing 14. Similarly, the second housing 14 and the third housing 15 can be connected by a plug-in protrusion 11 and a plug-in groove 12, and a first sealing structure 2 is provided between the second housing 14 and the third housing 15 to ensure the sealing of the connection between the second housing 14 and the third housing 15, thereby reducing the possibility of external particles such as salt spray entering the mounting cavity from the connection between the second housing 14 and the third housing 15. This effectively protects the various electronic components in the mounting cavity and improves the service life of each electronic component.

[0046] Therefore, when there are any number of housings 1, a first sealing structure 2 can be provided between two adjacent housings 1, which can enhance the sealing between the connected housings 1, thereby improving the overall sealing of the housing structure 100 of the controller.

[0047] Furthermore, the controller housing structure 100 can be completely sealed, which can prevent the controller housing structure 100 from directly contacting the environment, reduce the impact of salt spray particles in the environment on the controller housing structure 100, and thus reduce the corrosion of the controller housing structure 100 and the internal structure of the housing 1.

[0048] In some embodiments, the second housing 14 is formed with a housing cavity 141 extending along a first direction, the first housing 13 is closed at one end of the housing cavity 141, and the third housing 15 is closed at the other end of the housing cavity 141.

[0049] Specifically, such as Figures 3-5As shown, the first housing 13, the second housing 14, and the third housing 15 are distributed sequentially along the first direction. The second housing 14 forms a housing cavity 141 that extends through the first direction. That is, the housing cavity 141 has open sides on both sides along the first direction. During installation, the first housing 13 is connected to one end of the housing cavity 141 to close one end of the housing cavity 141, and the third housing 15 is connected to the other end of the housing cavity 141 to close the other end of the housing cavity 141. In this way, the housing cavity 141 is closed by the first housing 13 and the third housing 15 to form an installation cavity. Electronic components can be installed in the installation cavity from one open side of the housing cavity 141. The installation process is simple and facilitates the maintenance of electronic components.

[0050] Furthermore, by setting the second housing 14 to extend through the first direction, setting the first housing 13 to connect one end of the second housing 14, and setting the third housing 15 to connect the other end of the second housing 14, the connection of the three can be made simpler and more convenient, and the processing process can be made simpler and more convenient.

[0051] A sealing gap 121 is formed between the insertion protrusion 11 and the insertion groove 12. The sealing gap 121 extends in multiple bends between the inner cavity 141 of the housing and the external space. The first sealing structure 2 fills the sealing gap 121.

[0052] Specifically, such as Figure 2 As shown, a two-layer structure can be formed on the inner and outer sides of the insertion groove 12 at the connection position of the housing 1. After the insertion groove 12 and the insertion protrusion 11 are inserted and engaged, a sealing gap 121 is formed between them. The sealing gap 121 extends in multiple bends at the engagement point of the insertion groove 12 and the insertion protrusion 11, that is, multiple gaps are bent and connected. The distance between the insertion groove 12 and the insertion protrusion 11 is the size of the sealing gap 121. In this way, after the insertion protrusion 11 is inserted into the insertion groove 12, the external space will be connected to the inner cavity 141 of the housing through the sealing gap 121. The sealing gap 121 extends in multiple bends, which allows external particles to be transmitted along the path of multiple bends. Compared with a straight path, the distance of external particles from the external space to the inner cavity 141 of the housing is increased, which can reduce the possibility of external particles such as salt spray entering the inner cavity 141 of the housing.

[0053] Furthermore, by filling the sealing gap 121 with the first sealing structure 2, the sealing gap 121 can be sealed by the first sealing structure 2, thereby sealing the insertion joint of the insertion protrusion 11 and the insertion groove 12, thus isolating the external space from the inner cavity 141 of the housing, reducing the entry of particles such as salt spray into the inner cavity 141 of the housing, thereby reducing the corrosion of the structure in the inner cavity 141 of the housing, and improving the safety of the structure in the inner cavity 141 of the housing.

[0054] Furthermore, the first sealing structure 2 can fill the entire sealing gap 121, or it can only fill the area between the outer wall structure of the insertion groove 12 and the mating surface of the housing 1. The outermost part of the sealing gap 121 can be sealed. All these sealing methods can reduce the possibility of particles such as salt spray entering the inner cavity 141 of the housing.

[0055] The sealing gap 121 is constructed with multiple bends and extensions. For example, the sealing gap 121 can be constructed as a U-shape, a Z-shape, etc.

[0056] Furthermore, by providing a sealing fit gap 121 between the insertion protrusion 11 and the insertion groove 12, the insertion protrusion 11 and the insertion groove 12 can be in a clearance fit. The clearance fit makes the installation process easier and more convenient, and saves assembly time.

[0057] In some embodiments, there are multiple insertion grooves 12, which are spaced apart along the circumference of the housing 1, and multiple insertion protrusions 11, which are distributed in a one-to-one correspondence with the multiple insertion grooves 12.

[0058] In the specific design, the number of insertion grooves 12 and insertion protrusions 11 are matched. There are multiple insertion grooves 12 and multiple insertion protrusions 11. The multiple insertion grooves 12 are distributed circumferentially around the housing 1. The insertion grooves 12 are recessed on the surface of one housing 1 in a direction away from the insertion protrusions 11, and the insertion protrusions 11 are protruded on the surface of the other housing 1 in a direction close to the insertion grooves 12. In this way, the insertion protrusions 11 and insertion grooves 12 can be inserted and matched. After the insertion protrusions 11 and insertion grooves 12 are connected, the two housings 1 can fit tightly together, which improves the sealing between the two housings 1.

[0059] Furthermore, by having multiple insertion protrusions 11 and multiple insertion grooves 12 distributed one-to-one, the multiple insertion protrusions 11 can be inserted into the insertion grooves 12 one-to-one, allowing the two housings 1 to be connected at multiple positions in the circumferential direction. This improves the uniformity of the connection between the two housings 1 in the circumferential direction, and further improves the tightness of the connection between the two housings 1 in the circumferential direction. This prevents salt spray particles from the external space from entering the housings 1 from the connection points, thereby reducing the corrosion of electronic components inside the housings 1 by salt spray particles.

[0060] The multiple insertion grooves 12 can be evenly spaced apart in the circumference of the housing 1, or they can be non-uniformly distributed in the circumference of the housing 1. The distribution method is diverse and can be flexibly selected according to actual needs.

[0061] In this embodiment, there are three housings 1, namely a first housing 13, a second housing 14, and a third housing 15. Multiple sets of insertion grooves 12 and insertion protrusions 11 are provided between the first housing 13 and the second housing 14 to improve the tightness and reliability of the connection between the first housing 13 and the second housing 14. Multiple sets of insertion grooves 12 and insertion protrusions 11 are provided between the second housing 14 and the third housing 15 to improve the tightness and reliability of the connection between the second housing 14 and the third housing 15.

[0062] In some embodiments, the first sealing structure 2 is constructed as a sealant or a heat dissipation adhesive, and the first sealing structure 2 is coated on the outer surface of the insertion protrusion 11 and / or the inner surface of the insertion groove 12.

[0063] Specifically, the first sealing structure 2 can be constructed as a sealant. The sealant is used for sealing, waterproofing, dustproofing, sound insulation, etc. The sealant is located between the insertion protrusion 11 and the insertion groove 12. The sealant can be applied only to the outer surface of the insertion protrusion 11, or only to the inner surface of the insertion groove 12, or the sealant can be applied to both the outer surface of the insertion protrusion 11 and the inner surface of the insertion groove 12. All three of these arrangements can seal the insertion protrusion 11 and the insertion groove 12 with the sealant after the insertion protrusion 11 is inserted into the insertion groove 12. The assembly process is simple, and the arrangement methods are diverse and can be flexibly selected.

[0064] Furthermore, the first sealing structure 2 can also be constructed as a heat-dissipating adhesive, which is used for heat dissipation, sealing, and waterproofing. The heat-dissipating adhesive is located between the insertion protrusion 11 and the insertion groove 12. The heat-dissipating adhesive can be applied only to the outer surface of the insertion protrusion 11, or only to the inner surface of the insertion groove 12, or the heat-dissipating adhesive can be applied to both the outer surface of the insertion protrusion 11 and the inner surface of the insertion groove 12. In all three configurations, after the insertion protrusion 11 is inserted into the insertion groove 12, the heat-dissipating adhesive can seal the insertion protrusion 11 and the insertion groove 12. This allows the controller housing structure 100 to simultaneously have the functions of heat dissipation and sealing. The assembly process is simple, and the configuration methods are diverse and can be flexibly selected.

[0065] Therefore, by using sealant and heat dissipation adhesive, the gap between the plug protrusion 11 and the plug groove 12 can be effectively sealed to prevent salt spray particles from the external space from entering the housing 1 from the connection point of the housing 1, thereby reducing the corrosion of electronic components inside the housing 1 by salt spray particles and improving the corrosion resistance of the controller housing structure 100.

[0066] In some embodiments, at least one housing 1 is provided with an electrical connection slot 16 for interlocking with an external electrical connector 3, and a second sealing structure 4 is provided between the inner wall of the electrical connection slot 16 and the electrical connector 3.

[0067] Specifically, the electrical connection slot 16 is used for connecting the electrical connector 3. The electrical connection slot 16 can be provided on one housing 1 or on multiple housings 1. Through the electrical connection slot 16 provided on the housing 1, the external electrical connector 3 can be inserted into the electrical connection slot 16. Through the electrical connector 3, the electronic components inside the housing 1 can be electrically connected to external circuits or external devices to achieve control of external devices and to monitor or receive external signals. Its connection method is simple and assembly is convenient.

[0068] Electrical connector 3 is connected to housing 1 via electrical connector slot 16. A gap exists between electrical connector 3 and electrical connector slot 16. A second sealing structure 4 is provided between the inner wall of electrical connector slot 16 and electrical connector 3 to seal the mating area. The second sealing structure 4 can be made of rubber or other elastic materials, giving it good elasticity. This elasticity allows the mating area between the inner wall of electrical connector slot 16 and electrical connector 3 to be reliably pressed, improving the sealing effect and effectively reducing the possibility of external particles entering.

[0069] By providing an electrical connection slot 16 for connecting an electrical connector 3 in one or more housings 1, multiple circuits can be formed between the internal electronic components of the housing 1 and the external structure to realize the input and output of various control signals. Furthermore, a second sealing structure 4 is provided between the inner wall of the electrical connection slot 16 and the electrical connector 3 for sealing, which can improve the sealing performance between the electrical connector 3 and the electrical connection slot 16.

[0070] Among them, electrical connector 3 can be different types of connectors.

[0071] In some embodiments, the second sealing structure 4 is configured as a contour ring, and the contour ring is distributed around the electrical connector 3 after the electrical connector 3 is inserted into the electrical connector slot 16.

[0072] Specifically, the second sealing structure 4 can be made of materials such as silicone. Silicone has a strong sealing effect and can play a good role in dust prevention and waterproofing. The second sealing structure 4 is constructed as a contour ring. The outer wall of the contour ring is connected to the inner wall of the electrical connection slot 16, so that the contour ring and the electrical connection slot 16 are integrated. During installation, after the electrical connector 3 is inserted into the electrical connection slot 16, the contour ring surrounds the electrical connector 3, and the inner peripheral wall of the contour ring is tightly connected to the outer peripheral wall of the electrical connector 3. This allows the contour ring to wrap around the outer periphery of the electrical connector 3. The contour ring can fill the gap between the electrical connector 3 and the electrical connection slot 16 to achieve a seal at the connection between the electrical connector 3 and the electrical connection slot 16.

[0073] Therefore, by setting a contour ring, the gap between the electrical connector 3 and the electrical connection slot 16 can be effectively sealed to prevent salt spray particles from the external space from entering the housing 1 from the connection between the electrical connector 3 and the electrical connection slot 16, thereby reducing the corrosion of electronic components inside the housing 1 by salt spray particles and improving the corrosion resistance of the housing structure 100 of the controller.

[0074] The shape of the contour ring is matched with that of the electrical connector 3. The internal structure of the contour ring is different for different types of electrical connectors 3, which facilitates the tight connection between the contour ring and different types of electrical connectors 3 to seal the different types of electrical connectors 3.

[0075] In some embodiments, there are multiple electrical connection slots 16, which are spaced apart and distributed on the outer periphery of the housing 1, and each electrical connection slot 16 is provided with a second sealing structure 4.

[0076] In specific design, such as Figure 1 As shown, multiple electrical connection slots 16 are spaced apart on the outer periphery of the housing 1. The electrical connection slots 16 can penetrate the housing 1 along the inner and outer directions on one side of the housing 1. The multiple electrical connection slots 16 can be provided on the outer periphery of only one housing 1, or they can be provided on the outer periphery of multiple housings 1. Each electrical connection slot 16 is provided with a second sealing structure 4. The second sealing structure 4 can be glued to the electrical connection slot 16 as a whole, and the second sealing structure 4 forms a through hole. The electrical connector 3 is installed in the electrical connection slot 16 through the through hole. In this way, the second sealing structure 4 can press against the electrical connector 3 and the electrical connection slot 16 respectively, so that the multiple electrical connectors 3 are more tightly connected to the electrical connection slot 16.

[0077] Furthermore, by providing multiple electrical connection slots 16 in the housing 1, the connection between different circuits inside and outside the housing 1 can be achieved through multiple electrical connectors 3, enabling the input and output of various signals. In addition, a second sealing structure 4 is provided between the inner wall of each electrical connection slot 16 and each electrical connector 3, which can improve the sealing performance between each electrical connector 3 and each electrical connection slot 16, so as to prevent salt spray particles from the external space from entering the housing 1 from the connection between the electrical connector 3 and the electrical connection slot 16, thereby reducing the corrosion of electronic components inside the housing 1 by salt spray particles.

[0078] The multiple electrical connection slots 16 can be evenly spaced apart in the circumference of the housing 1, or they can be non-uniformly distributed in the circumference of the housing 1. The distribution method is diverse and can be flexibly selected according to actual needs.

[0079] In this embodiment, there are three housings 1, namely a first housing 13, a second housing 14, and a third housing 15. Multiple electrical connection slots 16 can be provided in only one of the first housing 13, the second housing 14, and the third housing 15, or multiple electrical connection slots 16 can be provided in two of the first housing 13, the second housing 14, and the third housing 15, or multiple electrical connection slots 16 can be provided in all of the first housing 13, the second housing 14, and the third housing 15. The arrangement methods are diverse and can be flexibly selected.

[0080] It should be noted that the housing structure in this embodiment has good sealing performance and low requirements for the corrosion resistance of the metal raw materials. Magnesium alloy, which has poor corrosion resistance, can be used to manufacture the housing structure, allowing for a wide range of material choices. Furthermore, electrical connectors 3, which have lower protection properties, can be used, resulting in wider applicability and lower cost. Alternatively, electrical connectors 3 with higher protection can be used, thereby improving the overall protection level of the controller's housing structure 100, while also using metals with excellent corrosion resistance, such as stainless steel.

[0081] In some embodiments, the housing 1 is configured to include a conductive region 17 and a non-conductive region 18, both of which are coated with a conductive oxide layer, and a corrosion-resistant layer is coated on the outside of the conductive oxide layer in the non-conductive region 18.

[0082] Specifically, the housing 1 includes a conductive region 17 and a non-conductive region 18. The conductive region 17 can meet the requirement of conductivity, and the non-conductive region 18 can meet the requirement of non-conductivity. By distinguishing between the conductive region 17 and the non-conductive region 18 of the housing 1, it is beneficial to perform different surface treatments on the housing 1.

[0083] In the specific processing, the surface of the housing 1 requires multiple surface treatment steps. First, the entire surface of the housing 1 undergoes conductive oxidation treatment. Then, the conductive area 17 is masked. Finally, the non-conductive area 18 undergoes a surface treatment with stronger corrosion resistance. After the surface treatment is completed, the masked conductive area 17 becomes conductive, and the corrosion resistance of the non-conductive area 18 is increased. In addition to conductive oxidation surface treatment, other surface treatments with conductive properties can also be used.

[0084] The conductivity requirement here can be understood as the ability to conduct interference current within the controller's housing structure 100 through the conductive area 17, thereby reducing the impact of interference current on the operation of electronic components inside the housing 1, ensuring stable operation and high safety of the controller.

[0085] Therefore, by distinguishing between conductive and non-conductive surfaces on the housing 1, the housing 1 can simultaneously meet the requirements for corrosion resistance and conductivity after surface treatment, thus satisfying the performance requirements of the controller's housing structure 100.

[0086] And such as Figure 6 The example shown is a conductive region 17 and a non-conductive region 18 of the housing 1, but the arrangement of the conductive region 17 and the non-conductive region 18 can be selected according to actual needs.

[0087] This utility model also proposes a vehicle.

[0088] According to the vehicle of the present invention, a housing structure 100 of the controller of any of the above embodiments is provided. The housing structure is a support, fixing and protective structure of the controller. The housing structure includes at least two housings 1. The at least two housings 1 are connected by a plug-in protrusion 11 and a plug-in groove 12. The at least two housings 1 can form a multi-layer structure along the inside and outside direction at the plug-in mating point of the plug-in groove 12 and the plug-in protrusion 11, which lengthens the path for salt spray and other particles to enter the housing 1 and can reduce the possibility of salt spray particles entering the housing 1. A first sealing structure 2 is provided at the plug-in mating point of the plug-in groove 12 and the plug-in protrusion 11. Through the sealing effect, the possibility of salt spray particles entering the housing 1 is further reduced. In addition, an electrical connection slot 16 for connecting an electrical connector 3 is provided in the housing 1. A second sealing structure 4 is provided between the electrical connection slot 16 and the electrical connector 3. The second sealing structure 4 can make the connection between the electrical connection slot 16 and the electrical connector 3 tighter and achieve a sealing effect.

[0089] Therefore, it can effectively reduce the entry of salt spray particles from the external space into the housing 1, thereby reducing the corrosion of the housing 1 and electronic components such as the PCB board inside the housing 1, improving the corrosion resistance of the housing structure 100 of the controller, enhancing the adaptability of the housing structure 100 of the controller, extending the service life of the controller, and making the controller suitable for use in vehicles, thereby improving the control stability and reliability of the controller for other structures of the vehicle.
