Description

Technical Field

[0001] This utility model relates to the technical field of controllers, and in particular to an automotive controller. Background Technology

[0002] With the development of intelligent vehicles, intelligent electrical boxes have also emerged. The car controller has eliminated traditional fuses and relays, replacing them with electronic devices such as HSD, E-Fuse, and MOSFET for modular integration. The advantage of this integration is that the product structure is simpler and the car functions are more intelligent, but it also brings new problems.

[0003] Compared to traditional circuit boards, control boards in smart electrical boxes are more prone to short circuits and malfunctions in humid environments, potentially leading to safety accidents. Therefore, customers often require IP67 and IP69K protection ratings for controllers located in wet automotive areas such as the front compartment and chassis. This means the product must not malfunction after a short-term immersion in water to a depth of 1 meter and subjected to high pressure or steam injection. However, existing controllers have low protection ratings and cannot meet customer requirements. Therefore, further improving the protection level of controllers is an urgent issue that needs to be addressed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, an automotive controller, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a plastic housing 1 and an aluminum housing 8, which are detachably connected. A circuit board 9 connects the plastic housing 1 and the aluminum housing 8. A first sealing structure 6 and a second sealing structure 7 are provided between the plastic housing 1 and the aluminum housing 8. The first sealing structure 6 is located on the transverse end face of the aluminum housing 8, and the second sealing structure 7 is located on the longitudinal side face of the aluminum housing 8. A vent valve is connected to the aluminum housing 8. The top of the plastic housing 1 has a socket, and a conductive sheet 3 is embedded in the socket. The conductive sheet 3 is embedded in the socket at the top of the plastic housing 1 by injection molding. A press-fit bolt 2 is riveted to the conductive sheet 3. The plastic housing 1 has a sealing groove 1-7 that communicates with the socket. The bottom of the conductive sheet 3 is embedded along the socket and the sealing groove in sequence and connected to the circuit board 9. A first sealing layer is provided on the sealing groove 1-7. A first sealing structure 6 and a second sealing structure 7 are provided on the vehicle controller. The first sealing structure 6 is located on the transverse end face of the plastic housing 1, and the second sealing structure 7 is located on the longitudinal side face of the aluminum housing 8. The first sealing structure 6 and the second sealing structure 7 seal the vehicle controller in two vertical directions. The vehicle controller is also equipped with a vent valve, which balances the internal and external air pressure of the vehicle controller to ensure its stability. In addition, the gap between the conductive sheet 3 and the plastic housing 1 is sealed by the first sealing layer, further improving the protection level of the controller and greatly enhancing its protection level. This solves the technical problem of low protection level of controllers in the prior art. The crimping bolt 2 on the controller is connected to the external power harness terminal.

[0030] The first sealing layer is formed by applying sealant to the sealing groove 1-7 and bonding the sealant together. The sealant is bonded to the sealing groove 1-7 and the contact surface of the conductive sheet 3 to form a seal.

[0031] Example 2, based on Example 1, is an automotive controller, such as... Figure 1 , Figure 5 and, Figure 7 and Figure 8As shown, the conductive sheet 3 has a U-shaped longitudinal section. The top of the plastic housing 1 has two insertion holes, each of which connects to a sealing groove 1-7. The two ends of the conductive sheet 3 are sequentially embedded along the insertion holes and sealing grooves and connected to the circuit board 9. Both ends of the conductive sheet 3 are embedded in the insertion holes at the top of the plastic housing 1 through injection molding. The first sealing layer is provided on both sealing grooves 1-7. The press-fit bolt 2 is riveted to the middle of the conductive sheet 3. After the conductive sheet 3 is integrally formed, it is bent to form a conductive sheet 3 with a U-shaped longitudinal section. The top surface of the middle part of the conductive sheet 3 is the bonding surface 3-1, which is used to connect with the external wire harness terminal to transmit power to the circuit board 9. The bottom surface of the middle part of the conductive sheet 3 is the riveting surface 3-3, which is the plane used to rivet the press-fit bolt 2. After the two ends of the conductive sheet 3 are bent, they respectively form two pins 3-2 of the conductive sheet 3. The first sealing layer seals the gap between the conductive sheet 3 and the plastic housing 1, further improving the protection level of the controller and greatly enhancing its protection level.

[0032] Example 3, based on Example 2, a car controller, such as... Figure 4 , Figure 5 and Figure 6 As shown, the plastic housing 1 has a first U-shaped groove 1-6, and the first sealing structure 6 is located within the first U-shaped groove 1-6. The aluminum housing 8 has an annular rib 8-2. One end of the first sealing structure 6 extends out of the first U-shaped groove 1-6, and the extended end of the first sealing structure 6 has a groove. The annular rib 8-2 engages with the groove. The first U-shaped groove 1-6 is designed to limit and fix the first sealing structure 6. The first sealing structure 6 seals the lateral gap between the plastic housing 1 and the aluminum housing 8. After the bolt 4 presses the plastic housing 1 onto the aluminum housing 8, the first sealing structure 6 is pressed onto the aluminum housing 8 by the bolt 4 for sealing. The groove at the extended end of the first sealing structure 6, with the annular rib 8-2 engaging with it, further ensures the sealing effect of the first sealing structure 6.

[0033] Example 4, based on Example 3, a car controller, such as... Figure 4 and Figure 6 As shown, a boss 8-3 is vertically connected to the top of the aluminum shell 8. The second sealing structure 7 is a sealing ring, which is fitted onto the longitudinal side of the boss 8-3. The second sealing structure 7 is located between the boss 8-3 and the plastic shell 1. The second sealing structure 7 seals the longitudinal gap between the plastic shell 1 and the aluminum shell 8. The boss 8-3 provides support for the second sealing structure 7. Bolts 4 press the plastic shell 1 onto the aluminum shell 8. After the plastic shell 1 and the aluminum shell 8 are interlocked, the longitudinal end face of the plastic shell 1 presses against the second sealing structure 7 to achieve a seal.

[0034] Example 5, based on Example 4, a car controller, such as... Figure 5 and Figure 6 As shown, the first sealing structure 6 is either a sealing ring or a sealant layer. When the first sealing structure 6 is a sealing ring, the sealing ring is installed in the first U-shaped groove 1-6. When the first sealing structure 6 is a sealant layer, sealant is sprayed into the first U-shaped groove 1-6 to form a sealant layer. The controller uses either a sealant solution or a sealing ring solution. Preferably, the first sealing structure 6 is a sealing ring because using a sealant solution requires investment in automatic dispensing equipment, and the production cost of the first sealing structure 6 being a sealing ring is lower.

[0035] When the first sealing structure 6 is a sealant, the second sealing structure 7 can be fitted onto the boss 8-3 of the vehicle controller, or the second sealing structure 7 can be left unfitted onto the boss 8-3 of the vehicle controller. When the first sealing structure 6 is a sealant and the second sealing structure 7 is fitted onto the vehicle controller, the protection level of the vehicle controller is further improved. However, when the first sealing structure 6 is a sealant and the second sealing structure 7 is not fitted onto the boss 8-3 of the vehicle controller, it has been found in actual use that the protection level required by the vehicle controller of this application can still be achieved, and it is still within the design scope of this application.

[0036] Example 6, based on Example 5, a car controller, such as... Figure 1 and Figure 7 As shown, the top of the plastic housing 1 is provided with a U-shaped sidewall 1-5, and the conductive sheet 3 is located inside the U-shaped sidewall 1-5. A power cover 5 is snapped onto the U-shaped sidewall 1-5. The U-shaped sidewall 1-5 and the power cover 5 form a housing that surrounds and protects the conductive sheet 3, thereby improving the protection level of the vehicle controller.

[0037] Example 7, based on Example 6, a car controller, such as... Figure 1 , Figure 7 , Figure 9 and Figure 10 As shown, the power cover 5 has a second U-shaped groove 5-4, and the U-shaped sidewall 1-5 has a third U-shaped groove 1-2. The second U-shaped groove 5-4 and the third U-shaped groove 1-2 are inserted into each other. The corresponding insertion of the second U-shaped groove 5-4 and the third U-shaped groove 1-2 makes the connection between the power cover 5 and the U-shaped sidewall 1-5 more airtight, which can effectively prevent dust and water. The power cover 5 has an upper cable outlet 5-3, and a lower cable outlet 1-3 is also provided at the position corresponding to the plastic shell 1. Both the upper cable outlet 5-3 and the lower cable outlet 1-3 are semi-circular, forming a circular cable outlet hole to match the power cable harness.

[0038] Example 8, based on Example 7, a car controller, such as... Figure 9 and Figure 10 As shown, a mounting platform 1-4 is provided on the U-shaped sidewall 1-5, and a hanging nose 5-2 is provided on the groove wall of the second U-shaped groove 5-4. The mounting platform 1-4 and the hanging nose 5-2 are engaged. The engagement of the mounting platform 1-4 and the hanging nose 5-2 secures the power cover 5 to the U-shaped sidewall 1-5, thereby achieving a detachable connection between the power cover 5 and the U-shaped sidewall 1-5. The power cover 5 is provided with a handle 5-1, which is designed to facilitate its removal from the plastic housing 1.

[0039] Example 9, based on any one of Examples 1 to 8, a car controller, such as Figure 2 and Figure 4 As shown, the bottom of the aluminum housing 8 is provided with a heat sink 8-1, and the top surface of the boss 8-3 is provided with a thermally conductive adhesive layer 8-5. The heat generated by the controller is quickly transferred to the aluminum housing 8 through the thermally conductive adhesive layer 8-5, and finally dissipated by the heat sink 8-1.

[0040] Example 10, based on Example 9, a car controller, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the plastic housing 1 and the aluminum housing 8 are detachably connected by bolts 4; the plastic housing 1 is fixedly connected to the circuit board 9 by self-tapping screws 10; the top of the plastic housing 1 is provided with a connector adapter structure 1-1 that snaps into the waterproof connector. The plastic housing 1 has multiple through holes 1-8, and the aluminum housing 8 has a corresponding number of threaded portions 8-4. The bolts 4 pass through the through holes 1-8 and connect with the threaded portions 8-4 to achieve a detachable connection between the plastic housing 1 and the aluminum housing 8. The connector adapter structure 1-1 is designed to snap into the waterproof connector, thereby achieving the connection between the automotive controller and the waterproof connector. Several connector adapter structures 1-1 are distributed on the top of the plastic housing 1.

[0041] In Example 10, the rivet bolt 2 and the conductive sheet 3 are riveted together, with part of the bolt embedded inside the plastic housing 1. The conductive sheet 3 has pins 3-2 that extend from the inside of the plastic housing 1. After the circuit board 9 is installed inside the plastic housing 1, it is welded to the pins 3-2 of the conductive sheet 3. At other positions of the circuit board 9, multiple self-tapping screws 10 fix the circuit board 9 to the plastic housing 1. The plastic housing 1 has an annular groove 1-7 for holding sealant. The sealant is bonded to the annular groove 1-7 and the contact surface of the conductive sheet 3 to form a seal. Outside the plastic housing 1, around the rivet bolt 2, there is a U-shaped groove 1-2 and a mounting platform 1-4. Correspondingly, the power cover 5 is provided with a U-shaped groove 5-4 and a hanging nose 5-2. When the power cover 5 is assembled with the plastic shell 1, the second U-shaped groove 5-4 and the third U-shaped groove 1-2 are inserted into each other, and the hanging nose 5-2 is hung on the mounting plate 1-4. The power cover 5 is provided with an upper cable outlet 5-3, and a lower cable outlet 1-3 is also provided at the corresponding position of the plastic shell 1. The two together form a circular cable outlet hole, which matches the power harness. When the controller power supply needs to be repaired, the handle 5-1 of the power cover makes it easy to remove it from the plastic shell 1. The aluminum shell 8 is integrally provided with a boss 8-3, and on the boss 8 A second sealing structure 7 is fitted onto the longitudinal side of the -3. The first sealing structure 6 is arranged in the first U-shaped groove 1-6 on the transverse end face of the plastic shell 1. Then, the plastic shell 1 and the aluminum shell 8 are connected by a bolt 4 through the through hole 1-8 and the threaded part 8-4. The bolt 4 presses the plastic shell 1 onto the aluminum shell 8, and the sealing ring 6 is compressed, thereby achieving a seal between the first sealing structure 6 and the transverse end face of the aluminum shell 8. After the plastic shell 1 and the aluminum shell 8 are interlocked, the longitudinal end face of the plastic shell 1 squeezes the second sealing structure 7 to achieve a seal.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
