Description

Technical Field

[0001] This utility model relates to the field of automotive domain controller technology, specifically to a waterproof housing for an automotive domain controller. Background Technology

[0002] Automotive domain controllers are mostly installed in the front and rear compartments or under the passenger compartment of a car, which poses certain external environmental risks. For example, if a car drives through a road with deep water or at high speed in the rain, there is a risk that water droplets may enter the relevant connected devices on the automotive domain controller in the front and rear compartments or under the passenger compartment. As a core component of the automotive electronic system, the protection performance of the automotive domain controller is very important, and dustproof and waterproof requirements need to be considered.

[0003] Currently, automotive domain controller housings typically rely on tight contact between housings or the use of ordinary adhesives to prevent liquid ingress. However, because automotive domain controller housings have space reserved for mounting connectors, the waterproofing of connectors on the housings is not ideal. Utility Model Content

[0004] In view of this, the present invention provides a waterproof housing for an automotive domain controller to solve the problem that the waterproof effect of the connectors on the housing of the automotive domain controller is not ideal.

[0005] In a first aspect, this utility model provides a waterproof housing for an automotive domain controller, the waterproof housing comprising:

[0006] The outer casing is composed of a first housing and a second housing; the first housing and the second housing surround a mounting cavity suitable for mounting a circuit board;

[0007] A connector is provided on the first housing; the connector is provided in correspondence with the plug-in port of the circuit board;

[0008] A water-blocking component is vertically disposed on the top of the housing and extends toward the side where the plug is located, so that the water-blocking component blocks water droplets that fall obliquely into the plug.

[0009] Beneficial effects: In this embodiment, a water-blocking component is provided. When the vehicle domain controller is installed in the front or rear compartments or under the passenger compartment of a vehicle, it can effectively prevent the interface and the connectors mating with the interface from being intruded by moisture, thereby meeting the waterproof requirements of the connectors on the housing. Furthermore, this embodiment can integrate the first housing and the second housing into a single structural design, thereby further simplifying the overall structure of the housing, making the structure more compact, and improving the protection performance of the domain controller.

[0010] In one optional embodiment, the water-blocking assembly includes:

[0011] A first water-blocking edge is disposed on the top of the second housing; and the first water-blocking edge is inclined upward, so that the extension direction of the first water-blocking edge and the plane on which the first housing is located are provided with a first included angle A.

[0012] In one alternative implementation, the first included angle A is between 92° and 95°.

[0013] Beneficial effects: In this embodiment, by providing a first water-retaining edge on the top of the second housing, water droplets can be prevented from entering the domain controller's interfaces and connectors. Furthermore, by changing the tilt angle of the first water-retaining edge, water droplets with a vertical tilt angle of up to 15° can be prevented from entering the domain controller's interfaces and connectors, thus meeting the waterproof requirements of the connectors on the housing and improving the protection performance of the domain controller. Simultaneously, a certain tilt angle allows the first water-retaining edge to smoothly discharge blocked water droplets, preventing water droplets from entering the housing.

[0014] In one optional embodiment, the water-blocking assembly further includes:

[0015] The second water-blocking edge is disposed on both sides of the first water-blocking edge; the second water-blocking edge extends downward and tilts outward, so that the extension direction of the second water-blocking edge is provided with a second included angle B between it and the vertical direction.

[0016] In one alternative implementation, the second included angle B is between 2° and 5°.

[0017] Beneficial effects: In this embodiment, by providing second water-retaining edges on both sides of the first water-retaining edge, water droplets can be prevented from entering the domain controller's interfaces and connectors from both sides. Furthermore, by changing the tilt angle of the second water-retaining edges, water droplets with a vertical tilt angle of up to 15° can be prevented from entering the domain controller's interfaces and connectors from both sides, thus meeting the waterproof requirements of the connectors on the housing and improving the protection performance of the domain controller. Simultaneously, a certain tilt angle allows the second water-retaining edges to smoothly discharge the blocked water droplets, preventing water droplets from entering the housing.

[0018] In one alternative embodiment, the second water-blocking edge is connected to the first water-blocking edge by an arc-shaped plate.

[0019] Beneficial effects: In this embodiment, the second water-retaining edge and the first water-retaining edge are smoothly transitioned through an arc-shaped plate. When the first water-retaining edge blocks water droplets, they can flow along the arc-shaped plate onto the second water-retaining edge and then be smoothly discharged outwards. Furthermore, the arc-shaped plate can prevent technicians from being accidentally cut at the connection point between the first and second water-retaining edges during installation, thus providing a certain degree of protection.

[0020] In one optional embodiment, the first housing is provided with a first screw hole, and the second housing is provided with a second screw hole. The screw passes through the first screw hole and the second screw hole to fix the first housing and the second housing. The outer end face of the first housing is provided with an annular boss, which is corresponding to the first screw hole.

[0021] Beneficial effects: In this embodiment, an annular boss is provided. When water droplets splash or intrude into the first housing, the water droplets can flow directly down along the edge of the annular boss due to the obstruction of the annular boss. This can prevent water droplets from flowing into the first screw hole to a certain extent, thus playing a certain role in drainage and improving the protective effect of the housing.

[0022] In one alternative embodiment, the thickness of the annular boss is between 1.5 mm and 2.5 mm.

[0023] In one optional embodiment, a drain hole is provided at the bottom of the second housing, and the drain hole communicates with the mounting cavity.

[0024] Beneficial effects: In this embodiment, a drain hole is provided. When the water-blocking component does not block the water droplets, the water droplets may enter the inside of the housing. Or, due to the influence of the domain controller's working environment, condensation may occur inside the housing. Under the action of gravity, the water droplets will collect at the bottom of the housing and then be discharged outward from the drain hole, thereby preventing the water droplets from accumulating and damaging the circuit boards inside the domain controller's housing.

[0025] In one alternative embodiment, the waterproof housing further includes:

[0026] A pair of lugs are provided on the second housing; the drain hole is provided between the two lugs. Attached Figure Description

[0041] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] Automotive domain controllers are mostly installed in the front and rear compartments or under the passenger compartment of a car, which poses certain external environmental risks. For example, if a car drives through a road with deep water or at high speed in the rain, there is a risk that water droplets may enter the relevant connected devices on the automotive domain controller in the front and rear compartments or under the passenger compartment. As a core component of the automotive electronic system, the protection performance of the automotive domain controller is very important, and dustproof and waterproof requirements need to be considered.

[0043] Currently, automotive domain controller housings typically rely on tight contact between housings or the use of ordinary adhesives to prevent liquid ingress. However, because automotive domain controller housings have space reserved for mounting connectors, the waterproofing of connectors on the housings is not ideal.

[0044] In view of this, the present invention provides a waterproof housing for an automotive domain controller to solve the problem that the waterproof effect of the connectors on the housing of the automotive domain controller is not ideal.

[0045] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a waterproof housing for an automotive domain controller is provided, the waterproof housing including an outer shell 1, a plug interface 111, and a water-blocking component 3.

[0047] Specifically, in this embodiment, the outer casing 1 is composed of a first housing 11 and a second housing 12, which together form a mounting cavity suitable for mounting the circuit board 2. That is, space is reserved in the first housing 11 and the second housing 12 to mount the circuit board 2. The first housing 11 and the second housing 12 can be fixed using snap-fit ​​or clip-on methods, or they can be sealed with sealant while simultaneously bonding the components. Alternatively, a sealing strip can be embedded between the first housing 11 and the second housing 12 to further improve the overall sealing performance of the outer casing 1.

[0048] Furthermore, in this embodiment, the insertion interface 111 is formed on the first housing 11, and the insertion interface 111 is correspondingly provided with the insertion port 21 of the circuit board 2. During normal use, since the insertion interface 111 is in direct contact with the external environment, the insertion interface 111 and the connector that mates with the insertion interface 111 are easily affected by external water droplets.

[0049] Furthermore, in this embodiment, the water-blocking component 3 is vertically disposed on the top of the outer casing 1, and the water-blocking component 3 extends towards the side where the insertion interface 111 is located, so that the water-blocking component 3 blocks water droplets that fall obliquely into the insertion interface 111. Since the water-blocking component 3 can cover the surrounding part of the outer casing 1 to a certain extent after extending, it can partially shield the first outer casing 1 and play a protective role.

[0050] In this embodiment, a water-blocking component 3 is provided. When the vehicle domain controller is installed in the front or rear compartments or under the passenger compartment of a vehicle, it can effectively prevent the interface 111 and the connector mating with the interface 111 from being intruded by moisture, thereby meeting the waterproof requirements of the connectors on the housing. Furthermore, this embodiment can integrate the first housing 11 and the second housing 12 into a single structural design, further simplifying the overall structure of the outer shell 1, making the structure more compact, and improving the protection performance of the domain controller. Finally, the water-blocking component 3 provides waterproofing without interfering with the interface 111 and the connector, facilitating the insertion and removal of the connector.

[0051] Further, in an optional embodiment, the water-blocking assembly 3 includes a first water-blocking edge 31, which is disposed on the top of the second housing 12. For example... Figure 1 and Figure 5 As shown, the first water-blocking edge 31 is inclined upward, so that the extension direction of the first water-blocking edge 31 and the plane where the first housing 11 is located are provided with a first included angle A.

[0052] Furthermore, in an optional embodiment, the first included angle A is between 92° and 95°. For example, it can be 92°, 93°, 94°, or 95°. Of course, this embodiment is merely an example of the specific value of the first included angle A, but it is not a limitation. Those skilled in the art can make changes according to the actual situation to achieve the same technical effect.

[0053] In this embodiment, by providing a first water-retaining edge 31 on the top of the second housing 12, water droplets can be prevented from entering the domain controller's interface 111 and connectors. Furthermore, by changing the tilt angle of the first water-retaining edge 31, water droplets with a vertical tilt angle of up to 15° can be prevented from entering the domain controller's interface 111 and connectors, thus meeting the waterproof requirements of the connectors on the housing and improving the protection performance of the domain controller. Simultaneously, a certain tilt angle allows the first water-retaining edge 31 to smoothly discharge blocked water droplets, preventing water droplets from entering the outer casing 1.

[0054] Furthermore, in an optional embodiment, the water-blocking assembly 3 further includes a second water-blocking edge 32, which is disposed on both sides of the first water-blocking edge 31. Figure 1 and Figure 4 As shown, the second water-blocking edge 32 extends downward and tilts outward, so that a second included angle B is set between the extension direction of the second water-blocking edge 32 and the vertical direction.

[0055] Furthermore, in an alternative embodiment, the second included angle B is between 2° and 5°.

[0056] For example, it could be 2°, 3°, 4°, or 5°. Of course, this embodiment is merely an example of the specific value of the second included angle B, but it is not a limitation. Those skilled in the art can make changes according to the actual situation to achieve the same technical effect.

[0057] With this configuration, in this embodiment, after providing second water-blocking edges 32 on both sides of the first water-blocking edge 31, water droplets can be prevented from entering the domain controller's interface 111 and connectors from both sides. Furthermore, by changing the tilt angle of the second water-blocking edges 32, water droplets with a vertical tilt angle of up to 15° can be prevented from entering the domain controller's interface 111 and connectors from both sides, thereby meeting the waterproof requirements of the connectors on the housing and improving the protection performance of the domain controller. Simultaneously, a certain tilt angle allows the second water-blocking edges 32 to smoothly discharge the blocked water droplets, preventing water droplets from entering the housing 1.

[0058] Furthermore, in an optional embodiment, the second water-blocking edge 32 and the first water-blocking edge 31 are connected by an arc-shaped plate 33.

[0059] In this configuration, the second water-blocking edge 32 and the first water-blocking edge 31 are smoothly transitioned by an arc-shaped plate 33. When the first water-blocking edge 31 blocks water droplets, the water can flow along the arc-shaped plate 33 onto the second water-blocking edge 32 and then be smoothly discharged outwards. Furthermore, the arc-shaped plate 33 can prevent technicians from being accidentally cut at the connection point between the first water-blocking edge 31 and the second water-blocking edge 32 during installation, thus providing a certain degree of protection.

[0060] Furthermore, in an optional embodiment, the circuit board 2 is positioned on the first housing 11 by two positioning posts 113. The first housing 11 is provided with a first screw hole, and the second housing 12 is provided with a second screw hole. The screw 6 passes through the first screw hole and the second screw hole to fix the first housing 11 and the second housing 12. An annular boss 112 is provided on the outer end face of the first housing 11, and the annular boss 112 is correspondingly provided with the first screw hole.

[0061] With this configuration, in this embodiment, an annular boss 112 is provided. When water droplets splash or intrude into the first housing 11, the water droplets can flow directly down along the edge of the annular boss 112 due to the obstruction of the annular boss 112. This can prevent water droplets from flowing into the first screw hole to a certain extent, thus playing a certain role in drainage and improving the protective effect of the housing 1.

[0062] Furthermore, in an optional embodiment, the thickness of the annular boss 112 is between 1.5 mm and 2.5 mm. For example, the thickness of the annular boss 112 can be 1.5 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, or 2.5 mm. Of course, this embodiment is merely an example illustrating the specific value of the thickness of the annular boss 112, but it is not intended to limit the application. Those skilled in the art can modify it according to actual circumstances to achieve the same technical effect.

[0063] Furthermore, in an optional embodiment, the bottom of the second housing 12 is provided with a drain hole 4, which communicates with the mounting cavity.

[0064] With this configuration, in this embodiment, a drain hole 4 is provided. When the water-blocking component 3 does not block the water droplets, the water droplets may enter the interior of the housing 1. Or, due to the influence of the domain controller's working environment, condensation may occur inside the housing 1. Under the action of gravity, the water droplets will collect at the bottom of the housing 1 and then be discharged outward from the drain hole 4, thereby preventing the water droplets from accumulating and damaging the circuit board 2 inside the housing 1 of the domain controller.

[0065] Furthermore, in an optional embodiment, the waterproof housing further includes a pair of lugs 5 disposed on the second housing 12, and the drain hole 4 is disposed between the two lugs 5.

[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
