[0002] A vehicle controller is a device that integrates multiple system functional modules, such as DC / DC (direct current converter), DC / AC (integrated inverter), and OBC (on-board charger), to achieve centralized control of the vehicle. As vehicles become increasingly feature-rich, the integration of controllers also increases, leading to significant heat generation and electromagnetic interference issues. Prolonged exposure to high temperatures can shorten the lifespan of functional modules, and electromagnetic interference can easily disrupt surrounding electronic components, causing vehicle malfunctions. Furthermore, prolonged exposure to high-voltage radiation can negatively impact the health of occupants and compromise vehicle safety. Utility Model Content

The cavity can then be sealed by installing the cover onto the main body, offering convenient assembly and disassembly with high flexibility. The use of plastic or resin components reduces the overall weight of the housing, improving vehicle handling and facilitating the arrangement of functional modules within the cavity. A cooling assembly dissipates heat from the functional modules within the cavity, ensuring their normal operation and extending their lifespan. The cooling assembly is detachably installed within the cavity, allowing for adjustment of its size and position based on the location of the functional modules.

Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0034] Combined with appendix Figure 1 and attached Figure 2 The vehicle controller housing proposed in this utility model includes a main body 10 and a cover 20, which are detachably connected. Both the main body 10 and the cover 20 are made of plastic or resin. The main body 10 includes a functional cavity 101, which is an open cavity at the top for accommodating vehicle functional modules. The functional modules are used to control the vehicle. A cooling assembly 30 is provided inside the functional cavity 101. The cooling assembly 30 is detachably installed inside the functional cavity 101 for heat dissipation and cooling of the functional modules. Both the main body 10 and the cover 20 include an electromagnetic shielding layer 40 for electromagnetic shielding to prevent electromagnetic interference between the functional modules inside the functional cavity 101 and surrounding devices.

[0035] The main body 10 and the cover 20 are detachably connected. Functional modules can be arranged in the functional cavity 101 according to actual needs. The cover 20 can then be installed on the main body 10 to close the functional cavity 101. This design is convenient and flexible. The use of plastic or resin components reduces the overall weight of the housing, which helps improve the vehicle's handling performance and facilitates the arrangement of functional modules in the functional cavity 101. The cooling assembly 30 can dissipate heat and cool the functional modules arranged in the functional cavity 101 to ensure the normal operation of the functional modules and extend their service life. The cooling assembly 30 is detachably installed in the functional cavity 101 so that its size and installation position can be adjusted according to the position of the functional modules in the functional cavity 101. The electromagnetic shielding layer 40 enables electromagnetic shielding between the inside and outside of the functional cavity 101, which can improve the housing's resistance to electromagnetic interference and ensure the stability of the vehicle controller's operation.

[0036] See attached document Figure 1 The coordinate system in this invention defines the length direction of the main body 10 along the D1 direction, the width direction along the D2 direction, and the height direction (i.e., the up-down direction) along the D3 direction. This coordinate system is intended to illustrate the approximate positional, connection, or movement relationships of the components. It does not imply that the components in this invention must be strictly set or connected according to the above coordinate system; those skilled in the art can adjust it flexibly according to actual needs.

[0037] In one example, combined with appendix Figure 3 and attached Figure 4 The main body 10 includes a base plate 102 and a side plate 103. The side plate 103 is connected to the base plate 102 in a vertical direction, and the base plate 102 and the side plate 103 together form a functional cavity 101. At least one of the base plate 102 and the side plate 103 has a reinforcing member 11 at one end near the functional cavity 101. The reinforcing member 11 protrudes from the base plate 102 and / or the side plate 103, and is used to increase the overall strength of the main body 10. Compared with the metal controller in the prior art, this design can reduce the overall weight and ensure structural stability.

[0038] For example, the base plate 102 is a rectangular piece, and the number of side plates 103 is set to four.

[0039] For example, the base plate 102 and the side plate 103 are integrally formed.

[0040] For example, as shown in the appendix Figure 4As shown, the reinforcing member 11 includes a first reinforcing rib 111 and a second reinforcing rib 112 disposed on the base plate 102. At least one first reinforcing rib 111 extends along the length direction of the base plate 102, and at least one second reinforcing rib 112 extends along the width direction of the base plate 102. The first reinforcing rib 111 and the second reinforcing rib 112 are staggered to form a grid structure, which can increase the structural stability of the base plate 102.

[0041] Optionally, at least one end of the first reinforcing rib 111 in the length direction of the base plate 102 is connected to the side plate 103 in the length direction of the base plate 102.

[0042] Optionally, at least one end of the second reinforcing rib 112 in the width direction of the base plate 102 is connected to the side plate 103 in the width direction of the base plate 102.

[0043] For example, as shown in the appendix Figure 4 As shown, the reinforcing member 11 includes at least one third reinforcing rib 113 disposed on the side plate 103. The third reinforcing rib 113 extends along the height direction of the main body 10 and is used to increase the structural stability of the side plate 103.

[0044] Optionally, the lower end of the third reinforcing rib 113 is connected to the base plate 102, or the third reinforcing rib 113 is connected to the first reinforcing rib 111 and / or the second reinforcing rib 112.

[0045] In one example, the cover 20 is detachably connected to the body 10, as shown in the attached figure. Figure 4 As shown, the upper end of the side plate 103 is provided with a connecting edge 104, which is used to connect with the cover 20, and the connecting edge 104 extends protruding away from the functional cavity 101 along its own width direction. In another example, the side plate 103 is detachably connected to the cover 20 directly.

[0046] For example, the connecting edge 104 is screwed to the cover 20 to achieve a detachable connection. By providing a detachable cover 20 on the main body 10, it is convenient for subsequent maintenance and repair, and it is also convenient to replace the internal functional modules of the main body 10 to adjust the integrated functions of the controller according to actual needs. It is highly flexible. The setting of the connecting edge 104 helps to increase the contact and connection area between the main body 10 and the cover 20, which helps to ensure the stability of the connection.

[0047] In one example, as shown in the attached document Figure 4 As shown, a mounting member 12 protrudes from one end of the side panel 103 away from the functional cavity 101. The mounting member 12 is used to install the main body 10 into the vehicle. Exemplarily, the mounting member 12 is integrally formed with the side panel 103.

[0048] In one example, as shown in the attached document Figure 2As shown, the functional cavity 101 is provided with a partition 105, which is used to divide the functional cavity 101 into at least two cavities so as to adjust the arrangement space of the functional modules according to the functional requirements of the controller.

[0049] For example, as shown in the appendix Figure 4 As shown, the partition 105 includes a first partition 106 and a second partition 107. The first partition 106 extends along the length direction of the main body 10, and the second partition 107 extends along the width direction of the main body 10. One end of the first partition 106 is connected to a side plate 103 of the main body 10 in the length direction, and the other end is connected to the second partition 107. One end of the second partition 107 is connected to a side plate 103 of the main body 10 in the width direction. The first partition 106, the second partition 107 and the side plate 103 cooperate to form a cooling cavity, and the cooling assembly 30 is detachably installed in the cooling cavity.

[0050] For example, at least one of the first partition 106 and the second partition 107 is provided with a fixing member 108. The fixing member 108 protrudes from the side of the first partition 106 and / or the second partition 107 away from the cooling cavity. The upper end of the fixing member 108 is provided with a fixing hole for installing a functional module, such as a DC / DC module, a DC / AC module, an OBC module, etc.

[0051] In one example, as shown in the attached document Figure 1 As shown, the cover 20 includes a protrusion 21, which is combined with the attached... Figure 5 The protrusion 21 extends outward toward the end away from the main body 10, and the protrusion 21 includes an expansion cavity 22 located at the end of the protrusion 21 close to the main body 10. When the cover 20 is connected to the main body 10, the expansion cavity 22 communicates with the functional cavity 101 to increase the capacity of the functional cavity 101 and avoid functional modules, thereby improving the integration of the controller.

[0052] For example, the protrusion 21 is integrally formed with the cover 20.

[0053] For example, as shown in the appendix Figure 5 As shown, a plurality of positioning posts 221 are protruding inside the expansion cavity 22. The positioning posts 221 are used to cooperate with the functional modules located inside the functional cavity 101. By cooperating with the positioning holes on the functional modules, the installation quality of the functional modules is improved.

[0054] In one example, as shown in the attached document Figure 2As shown, the cooling assembly 30 includes a first cooling plate 31 and a second cooling plate 32. The first cooling plate 31 and the second cooling plate 32 are sealed together in the vertical direction, and the second cooling plate 32 is arranged below the first cooling plate 31. The upper end of the second cooling plate 32 is provided with a medium flow channel 321. The first cooling plate 31 and the second cooling plate 32 cooperate to enable the cooling medium to flow in the medium flow channel 321, thereby realizing the cooling and heat dissipation of the functional modules inside the functional cavity 101.

[0055] For example, the first cooling plate 31 is used to connect to the functional module, such as by directly attaching it to the bottom of the OBC, or by contacting it through a thermal pad or thermal adhesive, so as to provide good heat dissipation for the OBC.

[0056] For example, both the first cooling plate 31 and the second cooling plate 32 are made of aluminum alloy plates, which have good thermal conductivity and can improve the cooling effect.

[0057] For example, the first cooling plate 31 and the second cooling plate 32 are connected as one unit by welding.

[0058] For example, the medium flow channel 321 is formed on the second cooling plate 32 by a stamping process. Preferably, the medium flow channel 321 is formed by splicing together a number of S-shaped flow channels to arrange the medium flow channel 321 as long as possible on the second cooling plate 32, which is beneficial to improving the uniformity and efficiency of cooling.

[0059] For example, as shown in the appendix Figure 4 As shown, the main body 10 includes a first medium connector 13 and a second medium connector 14. The first medium connector 13 and the second medium connector 14 are disposed on the side plate 103 of the main body 10 and are used to connect the medium flow channel 321 and the outside of the main body 10. The cooling medium can enter the medium flow channel 321 through one of the first medium connector 13 and the second medium connector 14, and flow out of the medium flow channel 321 through the other, so as to form a circulation of the cooling medium. Optionally, the cooling medium is a coolant.

[0060] For example, the cooling assembly 30 is installed in the functional cavity 101 by screwing; more specifically, the cooling assembly 30 is detachably installed on the base plate 102 by screwing, as shown in the attached figure. Figure 2 As shown, the first cooling plate 31 and / or the second cooling plate 32 are provided with mounting edges 311. The mounting edges 311 are connected to the base plate 102 by fasteners 312, thereby completing the installation of the cooling assembly 30. Optionally, the fasteners 312 are bolts, which facilitates subsequent maintenance and replacement of the cooling assembly 30.

[0061] In one example, the electromagnetic shielding layer 40 includes a metal mesh layer disposed on the outer wall of the main body 10 and the outer wall of the cover 20. Both the main body 10 and the cover 20 are made of PA6 (Polyamide 6) or epoxy resin. The metal mesh layer is integrally formed with the main body 10 and the cover 20 by PCM (Press and Cure Molding) process, which saves processing steps, helps to reduce processing costs, meets the needs of integrated design, and reduces the overall weight compared with the metal controller in the prior art, which helps to lower the center of gravity of the vehicle and improve the handling and stability performance of the vehicle. In addition, the metal mesh layer can increase the structural strength of the main body 10 and the cover 20.

[0062] For example, both the main body 10 and the cover 20 are made of PA6 + metal fiber composite materials. These composite materials possess good strength, corrosion resistance, and insulation properties, and can also provide thermal insulation. When cooled by the cooling assembly 30, each functional module can operate at a suitable temperature for an extended period. The low modulus of the composite material also reduces the risk of the shell intruding into the passenger compartment during a collision, thus improving vehicle collision safety. During the processing of the main body 10 and the cover 20, the metal mesh layer is pre-treated by impregnation and then placed in an appropriate position in the mold. Under specific temperature, pressure, and time conditions, it is cured and formed with the PA6 raw material.

[0063] In one example, the main body 10 and the cover 20 are sealed together, combined with the attached... Figure 2 and attached Figure 6 A sealing element 50 is provided between the main body 10 and the cover 20, combined with the attached Figure 6 The sealing element 50 includes a first sealing protrusion 51 and a second sealing protrusion 52. The first sealing protrusion 51 and the second sealing protrusion 52 are located on the side close to the cover 20 and extend protruding towards the side close to the cover 20. The first sealing protrusion 51 is located on the side of the second sealing protrusion 52 close to the functional cavity 101 in the length or width direction of the main body 10. When the main body 10 and the cover 20 are connected, the first sealing protrusion 51 and the second sealing protrusion 52 can increase the sealing of the connection, thereby ensuring the electromagnetic shielding performance of the controller housing.

[0064] For example, the first sealing protrusion 51 and the second sealing protrusion 52 are distributed at intervals along the length or width direction of the body 10.

[0065] For example, the first sealing protrusion 51 and the second sealing protrusion 52 are integrally formed.

[0066] For example, the lower end of the seal 50 is bonded to the body 10 to prevent the seal 50 from shifting and affecting the sealing effect when the cover 20 is connected. More specifically, the lower end of the seal 50 is bonded to the connecting edge 104.

[0067] For example, the sealing element 50 is made of conductive foam, which has good conductivity and shielding effect, is lightweight, has good flexibility and compression resistance, and can achieve good gap shielding effect, thereby improving the sealing performance of the connection between the main body 10 and the cover 20.

[0068] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
