The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.
[0032] Reference will be made below Figures 1-5 to describe a controller assembly 10 for a vehicle according to an embodiment of the present application. The controller assembly 10 includes a circuit board, a first housing 11 and a second housing 12. The circuit board has a body area and a communication area. The first housing 11 is disposed at the bottom of the circuit board and corresponds to the body area in the thickness direction. At least one mounting notch 111 is formed on the first housing 11. The second housing 12 is located at the mounting notch 111 and is detachably connected to the first housing 11. At least a part of the second housing 12 is configured as a plastic part, and the second housing 12 corresponds to the communication area in the thickness direction.
[0033] Currently, the controller housing is an important part of the new energy vehicle domain controller. The controller housing can meet the requirements of fixing the printed circuit board and protecting the circuit board while also meeting the requirements of the new energy vehicle domain controller for wireless networks. The main part of the existing controller housing uses a single material. In order to meet the requirement of the vehicle domain controller for wireless network communication with the outside world, the material selection of the controller housing can only be a plastic material without electromagnetic shielding effect. Compared with metal materials, plastic materials have poor thermal conductivity and are difficult to meet the heat dissipation requirements.
[0034] Specifically, the controller assembly 10 includes a circuit board and a controller housing. The circuit board assembly can be disposed inside the controller housing. The controller housing can include a controller upper housing and a controller lower housing. The controller upper housing and the controller lower housing are arranged and connected in sequence in the thickness direction. Among them, the controller upper housing and the controller lower housing can be detachably connected by screws or bolts, or the controller upper housing and the controller lower housing can be detachably connected by snap connection or plug connection. The controller lower housing can include a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are connected.
[0035] As Figure 1 and Figure 2As shown, further, the circuit board has a body area and a communication area. The communication area can be a wireless communication area. The first housing 11 can be located at the bottom of the circuit board, and the first housing 11 can be disposed opposite to the body area in the thickness direction. The size of the first housing 11 can be set according to the size of the body area. At least one mounting notch 111 can be formed on the first housing 11. The second housing 12 can be located at the mounting notch 111, and the second housing 12 is detachably connected to the first housing 11. Optionally, the second housing 12 and the first housing 11 are detachably connected by screws or bolts, or the second housing 12 and the first housing 11 are detachably connected by snap connection or plug connection. Disassembling the second housing 12 from the first housing 11 facilitates the repair of the circuit board. It can be disassembled separately according to the damaged position of the circuit board, improving the repair efficiency.
[0036] The second housing 12 can be arranged corresponding to the communication area in the thickness direction, and the second housing 12 can be configured as a plastic part, such as a plastic material like ABS material, etc. The plastic part can ensure the shielding of the transmission of electromagnetic signals, thus meeting the requirements of the circuit board for antenna emission signals. The size of the second housing 12 is larger than the size of the communication area to ensure that the second housing 12 can support the communication area. The first housing 11 can be configured as a metal part, and the metal part can ensure the normal heat dissipation of the circuit board. Thus, while ensuring that the controller assembly 10 can effectively dissipate heat from the circuit, it meets the requirements of the wireless network communication function of the circuit board. Among them, the first housing 11 and the second housing 12 can be formed by molding.
[0037] In short, the controller assembly 10 of the embodiment of the present application has a circuit board, a first housing 11 and a second housing 12. A body area and a communication area are formed on the circuit board. The first housing 11 can be disposed opposite to the body area in the thickness direction and dissipate heat from the body area. The second housing 12 can be arranged on the first housing 11 and opposite to the communication area. At least part of the second housing 12 is configured as a plastic part to meet the requirements of the wireless network communication function of the circuit board. Therefore, the controller assembly 10 can dissipate heat from the circuit board while ensuring the requirements of the wireless network communication function of the circuit board.

The first fastener 13 can be configured as a plurality of ones and respectively pass through the corresponding first mounting hole 112 and the second mounting hole 121. Using the plurality of first mounting holes 112 and the plurality of second mounting holes 121 can further improve the mating strength between the first housing 11 and the second housing 12.

A third mounting hole 115 can be formed on the fixing member 114, and a fourth mounting hole can be formed on the body area. The fourth mounting hole can be correspondingly arranged with the third mounting hole 115. The controller can include a second fastener. The second fastener can pass through the third mounting hole 115 and the fourth mounting hole to fix the body area on the first housing 11. Among them, the fixing member 114 can be configured as a plurality of ones, and the plurality of fixing members 114 can be spaced apart on the first housing 11. Using the plurality of fixing members 114 can improve the stability of the cooperation between the circuit board and the first housing 11.
[0041] As Figure 3As shown, in some embodiments of the present application, a support post 116 extending towards the circuit board is further formed on the first housing 11. The free end of the support post 116 can abut against the circuit board. Among them, the support post 116 can be configured as a metal part, and the circuit board can achieve the effect of grounding through the support post 116. Compared with the prior art, no additional grounding device is required, realizing the miniaturization, lightweight and integrated design of the controller assembly 10.
[0042] As Figure 3 shown, in some embodiments of the present application, a first side wall 117 is further formed on the outer periphery of the side of the first housing 11 facing the body area.

A second side wall 123 is further formed on the side of the second housing 12 facing the communication area. The second side wall 123 and the second housing 12 can define another partial receiving groove for receiving the communication area. A buckle 124 for engaging with the upper housing can be formed on the outer periphery of the second side wall 123. A limiting rib 1171 is further formed on the side of the first side wall 117 facing the body area. The limiting rib 1171 can ensure that the body area is spaced from the first side wall 117, preventing contact and wear between the body area and the first side wall 117. During actual installation, a clearance margin of 0.1 mm to 0.2 mm is reserved between the body area and the limiting rib 1171.
