[0026] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0028] Please refer to Figure 1-Figure 3 An embodiment of the utility model provides a snap-fit ​​structure 100, which includes a cover body and a bottom plate; the cover body has a containing chamber 101, the bottom plate and the cover body are snap-fitted to each other, and there is a gap 12 between the bottom plate and the cover body; wherein the bottom plate includes a water-flowing step 111, the water-flowing step 111 is close to the gap 12, and the water-flowing step 111 is used to guide the flow direction of the fluid to prevent the fluid from entering the containing chamber 101 through the gap 12.

[0029] It is worth noting that the buckle structure 100, through the setting of the water-draining step 111, allows the fluid to flow smoothly from the water-draining step 111 instead of flowing into the circuit board in the accommodating chamber 101 through the gap 12 at the connection, thereby improving the waterproof performance while ensuring economic costs.

[0030] like Figure 2 As shown, the water-dipping step 111 has an inclined groove surface 1111 with a circular arc transition.

[0031] It is worth noting that the beveled groove surface 1111 with a circular arc transition can more effectively guide the flow direction of the fluid, thereby reducing the time that the fluid stays on the surface of the water-flowing step 111 and preventing the risk of the fluid entering the gap 12. At the same time, the beveled groove surface 1111 with a circular arc transition can reduce sharp edges and protrusions, reducing the possibility of accidental injuries. Compared with a right-angle transition, the arc transition is smoother and can enhance the overall aesthetics of the water-flowing step 111. In addition, the beveled groove surface 1111 with a circular arc transition can allow the water to flow more smoothly and reduce the impact force of the water on the step surface. This helps to reduce wear and damage to the step surface.

[0032] Please refer again Figure 1 The bottom plate also includes a snap-on buckle 112, and the outer surface of the cover body has a snap-on boss 102 adapted to the snap-on buckle 112. The bottom plate and the cover body are snap-oned to each other through the snap-on buckle 112 and the snap-on boss 102. The design of the snap-on buckle 112 and the snap-on boss 102 provides a firm connection method, so that the bottom plate and the cover body can be tightly combined and not easy to loosen or separate. At the same time, the assembly process of the snap-on structure is simpler and faster, and no additional tools or complicated operations are required. After assembly, it has high visibility, which is convenient for checking whether it is assembled in place.

[0033] Please refer again Figure 2 The snap-fit ​​buckle 112 includes a guiding portion 1121 and abutting portion 1122 . The guiding portion 1121 and the abutting portion 1122 cooperate with each other to form a snap-fit ​​buckle 112 with a “U”-shaped cross section. The abutting portion 1122 abuts against the snap-fit ​​boss 102 .

[0034] It is worth noting that the design of the snap-fit ​​buckle 112 with a "U"-shaped cross section formed by the guide portion 1121 and the abutment portion 1122, and the abutment with the snap-fit ​​boss 102, can achieve the technical effects of precise alignment, stable connection, simple installation and enhanced sealing. Depending on the specific implementation environment, the guide portion 1121 and the abutment portion 1122 can also form other structures such as "V" shape and "H" shape. This embodiment is only an example of its structural type and does not constitute a limitation on the specific type.

[0035] Please refer again Figure 2 The outer surface of the abutment portion 1122 has a reinforcing boss 1123. It is understandable that by reinforcing the weld mark on the outer surface of the abutment portion 1122 (i.e., forming the reinforcing boss 1123), the strength, durability and safety of the snap buckle 112 can be effectively enhanced, while improving its appearance, enhancing the user experience and aesthetics.

[0036] In this embodiment, the outer surface of the cover body further has a guide rib 103 , and the extending direction of the guide rib 103 is the same as the extending direction of the guide portion 1121 .

[0037] It is worth noting that the extension direction of the guide rib 103 is the same as the extension direction of the guide portion 1121, which can ensure that the cover can be accurately aligned with the bottom plate during the assembly process, which helps to simplify the assembly process and ensure the correct docking between components, thereby improving the accuracy and efficiency of assembly. At the same time, the design of the guide rib 103 can increase the mechanical strength of the cover, making it more resistant to external impact and vibration, thereby extending the service life of the product, reducing the frequency of maintenance and replacement, and reducing the cost of use.

[0038] Please refer again Figure 3 The cover body includes an outer shell 104 and an inner wall 105. The outer shell 104 cooperates with itself to enclose a receiving chamber 101. The inner wall 105 is located in the receiving chamber 101. The bottom plate also includes a positioning wall 113 extending into the receiving chamber 101, and the positioning wall 113 is located between the inner wall 105 and the outer shell 104.

[0039] It is worth noting that, through the combination of the outer shell 104 and the inner wall 105 and the positioning wall 113 of the bottom plate, a stable structure can be formed to effectively support and protect the internal circuit board and prevent it from being affected by external impact or vibration. At the same time, since the positioning wall 113 of the bottom plate is located between the inner wall 105 and the outer shell 104, the structure can provide an additional protective layer to protect the circuit board inside the accommodating chamber 101 from the influence of the external environment, such as further preventing dust or moisture from intruding.

[0040] In this embodiment, the end surface of the inner wall 105 has an upper cover pressure point 106, and the inner surface of the positioning wall 113 has a bottom plate pressure point 107. The upper cover pressure point 106 and the bottom plate pressure point 107 are arranged opposite to each other and can cooperate with each other for installing the circuit board.

[0041] It is worth noting that the cooperation between the upper cover pressure point 106 and the bottom plate pressure point 107 can ensure that the circuit board remains firmly fixed during the installation process, preventing circuit failure or other problems caused by loosening or displacement of the circuit board. In addition, the design of the upper cover pressure point 106 and the bottom plate pressure point 107 makes the installation process of the circuit board easier, and the installer only needs to correctly place the circuit board in the corresponding position without the need for additional tools or complicated operations.

[0042] In this embodiment, the number of the upper cover pressure points 106 is multiple, and the multiple upper cover pressure points 106 are arranged at intervals on the end surface of the inner wall 105. It can be understood that in one implementation of this embodiment, the number of the upper cover pressure points 106 is two (such as Figure 3As shown in FIG. 1 , two upper cover pressure points 106 are respectively located on both sides of the bottom plate pressure point 107. In this embodiment, since the upper cover pressure points 106 are located on both sides of the bottom plate pressure point 107, the circuit board is supported evenly, which can reduce uneven pressure distribution, thereby protecting the circuit board and improving its stability. At the same time, the upper cover pressure points 106 on both sides can effectively prevent the circuit board from being twisted or deformed during the installation process, which helps to ensure the normal working state of the circuit board and reduce the occurrence rate of failures. Depending on the specific implementation environment, the number of upper cover pressure points 106 can also be 3, 4, etc., and this embodiment does not constitute a limitation on the number of upper cover pressure points 106.

[0043] The embodiment of the utility model further provides a vehicle body controller, including the buckle structure 100 as described above, having all the beneficial effects thereof.
