Description

Technical Field

[0001] This application relates to the field of controller technology, and more particularly to a controller and a vehicle. Background Technology

[0002] In vehicle electronic control systems, controllers, as core components, are widely distributed in various locations within the vehicle. Controllers located in wet areas or other areas prone to water immersion, if not designed with a waterproof structure, are susceptible to short circuits in their internal circuit boards due to water ingress, leading to functional failure.

[0003] In related technologies, in order to make the controller waterproof and breathable, a vent is usually made on the controller housing, and a waterproof and breathable membrane is placed at the vent.

[0004] However, the breathable membrane has limited water pressure resistance, making it difficult for the controller to meet higher waterproof ratings, such as the 9K waterproof rating in the IP69K rating. Utility Model Content

[0005] This application provides a controller and a vehicle, which aims to at least solve the technical problem that controllers in the related art are unable to meet higher waterproof ratings.

[0006] In a first aspect, embodiments of this application provide a controller, including a first housing and a waterproof and breathable membrane. A vent is provided on a first plate of the first housing to communicate with the inside and outside of the first housing. The waterproof and breathable membrane is disposed on the inner side of the first plate and is located on the side of the vent facing the inside of the first housing. The ventilation hole includes a first hole segment and a second hole segment that are connected to each other. The first hole segment and the second hole segment are arranged sequentially along the thickness direction of the first plate. The center line of the first hole segment is parallel to the center line of the second hole segment and is not on the same straight line.

[0007] Optionally, the vent further includes a connecting hole section, one end of which is connected to the first hole section and the other end of which is connected to the second hole section; The centerline of the connecting hole segment is not on the same straight line as the centerline of the first hole segment, and the centerline of the connecting hole segment is not on the same straight line as the centerline of the second hole segment 1. The cross-sectional area of ​​the connecting hole segment is smaller than the cross-sectional area of ​​the first hole segment and smaller than the cross-sectional area of ​​the second hole segment.

[0008] Optionally, the first plate is a side plate of the first housing.

[0009] Optionally, the inner surface of the first plate is provided with at least two fixing structures, and the waterproof and breathable membrane is welded to at least two of the fixing structures; At least one of the fixing structures is a ring-shaped rib; multiple fixing structures are arranged sequentially from the center of the waterproof and breathable membrane to the edge.

[0010] Optionally, each of the fixing structures has a first inclined surface and a second inclined surface, the first inclined surface intersecting the second inclined surface, and the intersection is located at the end of the fixing structure used for welding to the waterproof and breathable membrane.

[0011] Optionally, the maximum wall thickness of the fixing structure is 0.5mm-1mm in the direction from the center of the waterproof and breathable membrane to the edge; Along the thickness direction of the first plate, the height of the fixing structure is 0.2mm-0.4mm.

[0012] Optionally, the controller further includes a second housing, which is connected to the lower part of the first housing, and the first housing and the second housing together form an accommodating cavity; The controller also includes a circuit board located in the accommodating cavity, and the circuit board is thermally riveted to the first housing.

[0016] In this embodiment, the center line of the first hole segment in the vent is parallel to the center line of the second hole segment, but not on the same straight line, thus forming a staggered ventilated structure. For high-pressure water washing scenarios, the staggered part of the staggered ventilated structure, that is, the end of the first hole segment close to the second hole segment, can reduce some water pressure, thereby reducing the water pressure at the waterproof ventilated membrane, improving the overall waterproof effect, and enabling the controller to achieve a higher waterproof rating.

[0017] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application, it can be implemented according to the contents of the specification.

Detailed Implementation

[0020] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0021] In related technologies, to enable controllers to be waterproof and breathable, ventilation holes are typically made in the controller housing, and a waterproof and breathable membrane is installed at these holes. However, the water pressure resistance of the breathable membrane is limited, making it difficult for the controller to meet higher waterproof ratings, such as the 9K waterproof rating in IP69K. To solve the above problems, embodiments of this application provide a controller and a vehicle, which are described in detail below.

[0022] Firstly, referring to Figures 1 to 6 This application provides a controller, including a first housing 10 and a waterproof and breathable membrane 20. The first plate 11 of the first housing 10 has a vent 12 that connects the inside and outside of the first housing 10. The waterproof and breathable membrane 20 is disposed on the inner side of the first plate 11 and is located on the side of the vent 12 facing the inside of the first housing 10. The vent 12 includes a first hole segment 121 and a second hole segment 122 that are connected. The first hole segment 121 and the second hole segment 122 are arranged sequentially along the thickness direction of the first plate 11. The center line of the first hole segment 121 is parallel to the center line of the second hole segment 122 and is not on the same straight line.

[0023] The controller can be installed inside a vehicle. The waterproof and breathable membrane 20 is breathable but waterproof, preventing liquid water from entering the controller while allowing air to pass through. The waterproof and breathable membrane 20 has several micropores to allow air to pass through; the diameter of the micropores can be less than or equal to 0.5 μm. The materials of the waterproof and breathable membrane 20 include, but are not limited to, PE (Polyethylene), PTFE (Polytetrafluoroethylene), ePTFE (expanded PTFE), and hydrophobic PVDF (Polyvinylidene fluoride).

[0024] The controller has a vent hole 12 on its first housing 10 and a waterproof and breathable membrane 20 covering the side of the vent hole 12 facing the inside of the first housing 10. This not only provides waterproof and dustproof protection but also allows for air circulation. Furthermore, the vent valve is eliminated, which reduces the number of controller components and lowers costs.

[0025] The number of vent holes 12 can be one or more. When there is only one vent hole 12, the waterproof and breathable membrane 20 completely covers that single vent hole 12. When there are multiple vent holes 12, the waterproof and breathable membrane 20 completely covers all the vent holes 12. When there are multiple vent holes 12 and the size of the vent holes 12 is small, it can prevent larger dust particles from entering between the first plate 11 and the waterproof and breathable membrane 20, thus preventing the waterproof and breathable membrane 20 from becoming clogged and affecting the breathability.

[0026] The first housing 10 can be the upper housing of the controller. As an example, the first plate 11 is the side plate of the first housing 10, and the thickness direction of the first plate 11 and the width direction of the controller can be referenced. Figure 1 and Figure 4 The direction indicated by arrow E, that is, the thickness direction of the first plate 11, is parallel to the width direction of the controller. The length direction of the controller can be referenced. Figures 1 to 3 , Figure 7 The height direction of the direction controller indicated by the arrow D can be referenced. Figure 2 and Figure 3The direction indicated by the arrow Z1 in the middle.

[0027] The centerlines of the first hole segment 121 and the second hole segment 122 can be parallel to the thickness direction of the first plate 11. The first hole segment 121 and the second hole segment 122 can be square, circular, triangular, elliptical, oblong, or irregularly shaped holes, etc. The cross-sectional shapes of the first hole segment 121 and the second hole segment 122 can be the same. The cross-section of the first hole segment 121 and the second hole segment 122 refers to the section perpendicular to its respective centerline.

[0028] As an example, refer to Figure 3 The first plate 11 is the side plate of the first housing 10. The thickness direction of the first plate 11 is parallel to the width direction of the controller. There are four vent holes 12. Two of the four vent holes 12 are opposite each other along the height direction of the controller. The center lines of the first hole segment 121 and the second hole segment 122 of the two vent holes 12 are misaligned along the height direction of the controller. The other two vent holes 12 are opposite each other along the length direction of the controller. The center lines of the first hole segment 121 and the second hole segment 122 of the two vent holes 12 are misaligned along the length direction of the controller.

[0029] In this embodiment, the center line of the first hole segment 121 in the vent 12 is parallel to the center line of the second hole segment 122 and is not on the same straight line, thus forming a staggered ventilated structure. For high-pressure water washing scenarios, the staggered part of the staggered ventilated structure, that is, the end of the first hole segment 121 that is close to the second hole segment 122, can reduce some of the water pressure, thereby reducing the water pressure at the waterproof breathable membrane 20, improving the overall waterproof effect, and enabling the controller to achieve a higher waterproof rating.

[0030] This controller can achieve protection levels such as IP67, TP68, and IP69K. In IP67, TP68, and IP69K, 6 refers to the dustproof level, and 7, 8, and 9K refer to the waterproof level. This controller can be installed anywhere in the vehicle.

[0031] In some embodiments, refer to Figure 5 The vent 12 also includes a connecting hole segment 123, one end of which is connected to the first hole segment 121, and the other end of which is connected to the second hole segment 122. The center line of the connecting hole segment 123 is not on the same straight line as the center line of the first hole segment 121, and the center line of the connecting hole segment 123 is not on the same straight line as the center line of the second hole segment 122. The cross-sectional area of ​​the connecting hole segment 123 is smaller than the cross-sectional area of ​​the first hole segment 121 and smaller than the cross-sectional area of ​​the second hole segment 122.

[0032] In this context, the cross-sectional areas of the first hole segment 121, the connecting hole segment 123, and the second hole segment 122 refer to the area at their respective cross-sections. The cross-sections of the first hole segment 121, the connecting hole segment 123, and the second hole segment 122 refer to the sections perpendicular to their respective centerlines. The cross-sectional area of ​​the first hole segment 121 can be equal to or unequal to the cross-sectional area of ​​the second hole segment 122.

[0033] The cross-sectional shape of the connecting hole segment 123 can be the same as that of the first hole segment 121 and the second hole segment 122. The centerline of the connecting hole segment 123 is not collinear with the centerline of the first hole segment 121, and the centerline of the connecting hole segment 123 is not collinear with the centerline of the second hole segment 122. Along the thickness direction of the first plate 11, the depth of the connecting hole segment 123 can be less than the depth of the first hole segment 121, and the depth of the connecting hole segment 123 can be equal to the depth of the second hole segment 122.

[0034] Preferably, when the cross-sectional shape of the first hole segment 121, the connecting hole segment 123, and the second hole segment 122 are all square, the first hole segment 121, the connecting hole segment 123, and the second hole segment 122 each have four sidewalls. Along the misalignment direction of the center lines of the first hole segment 121 and the second hole segment 122, the connecting hole segment 123 has two opposing first sidewalls. One of the first sidewalls of the connecting hole segment 123 can be flush with one sidewall of the first hole segment 121, and the other first sidewall of the connecting hole segment 123 can be flush with one sidewall of the second hole segment 122.

[0035] In this embodiment, by setting the first hole segment 121, the connecting hole segment 123, and the second hole segment 122 whose center lines are not on a straight line, a three-segment staggered structure can be formed, which can further improve the effect of water pressure relief, thereby further improving the overall waterproof effect.

[0036] In some embodiments, refer to Figure 1 , Figure 2 and Figure 7 The first plate 11 is a side plate of the first housing 10. The thickness direction of the first plate 11 can be the same as the width direction of the controller, that is... Figure 1 and Figure 7 The direction indicated by the arrow E in the middle is parallel, or it can be parallel to the length direction of the controller, that is... Figure 1 , Figure 2 , Figure 3 and Figure 7 The direction indicated by the arrow D is parallel. The thickness direction of the first plate 11 is preferably parallel to the width direction of the controller. In this embodiment, the first plate 11 is a side plate of the first housing 10, which can prevent foreign objects from blocking the vent hole 12 and ensure the air permeability.

[0037] In some embodiments, refer to Figures 4 to 6 The inner surface of the first plate 11 is provided with at least two fixing structures, and the waterproof and breathable membrane 20 is welded to at least two fixing structures; at least one fixing structure is an annular rib 13; multiple fixing structures are arranged in sequence from the center of the waterproof and breathable membrane 20 to the edge.

[0038] The waterproof and breathable membrane 20 can be welded to the fixed structure using methods such as hot-melt welding or ultrasonic welding. The direction from the center of the waterproof and breathable membrane 20 to the edge can be referenced... Figure 4 The direction indicated by arrow Z2. The waterproof and breathable membrane 20 is a circular membrane. Preferably, there are two fixing structures. One fixing structure is a circular annular rib 13, and the other fixing structure includes multiple arc-shaped ribs 14. The multiple arc-shaped ribs 14 are arranged in a ring around the circumference of the waterproof and breathable membrane 20, with adjacent arc-shaped ribs 14 spaced apart. The number of arc-shaped ribs 14 in the fixing structure can be 2, 3, 4, etc. Figure 6 From this perspective, the outermost ring consists of multiple curved ribs 14, and the innermost ring rib 13 can be seen through the gap between two adjacent curved ribs 14.

[0039] In this embodiment, the welding strength of the waterproof and breathable membrane 20 can be improved by setting at least two fixing structures, thereby improving the fixing effect of the waterproof and breathable membrane 20 and effectively preventing the waterproof and breathable membrane 20 from falling off under high-pressure water washing. In addition, the setting of the annular rib 13 can ensure the sealing performance and prevent water from entering the controller through the gaps in the fixing structures.

[0040] In some embodiments, refer to Figure 5 Each fixing structure has a first inclined surface 15 and a second inclined surface 16, the first inclined surface 15 and the second inclined surface 16 intersect, and the intersection is located at the end of the fixing structure used for welding with the waterproof and breathable membrane 20.

[0041] In this design, the first inclined surface 15 and the second inclined surface 16 intersect to form a sharp angle, the angle of which can be less than 90 degrees. In different fixing structures, the heights of the first inclined surface 15 and the second inclined surface 16 can be different, the angles of inclination of the first inclined surface 15 and the second inclined surface 16 relative to the inner surface of the first plate 11 can be different, and the angle of the sharp angle formed by the intersection of the first inclined surface 15 and the second inclined surface 16 can be different. For example, for the annular rib 13, along the thickness direction of the first plate 11, the heights of the first inclined surface 15 and the second inclined surface 16 can be equal to the height of the annular rib 13, meaning the cross-sectional shape of the annular rib 13 is triangular. For the arc-shaped rib 14, along the thickness direction of the first plate 11, the heights of the first inclined surface 15 and the second inclined surface 16 can be less than the height of the arc-shaped rib 14, meaning the arc-shaped rib 14 only has a sharp angle at the end used for welding to the waterproof and breathable membrane 20.

[0042] It should be noted that the sharp angle formed by the intersection of the first inclined plane 15 and the second inclined plane 16 refers to the shape of the fixing structure before welding to the waterproof and breathable membrane 20. After welding, the shape of the sharp angle of the fixing structure may change.

[0043] In this embodiment, by setting the first inclined plane 15 and the second inclined plane 16 to intersect, and the intersection point to be located at the end of the fixed structure used for welding with the waterproof and breathable membrane 20, the welding penetration effect when the waterproof and breathable membrane 20 is welded to the fixed structure can be improved, thereby improving the welding reliability of the waterproof and breathable membrane 20.

[0044] In some embodiments, the maximum wall thickness of the fixing structure is 0.5mm-1mm in the direction from the center of the waterproof and breathable membrane 20 to the edge; and the height of the fixing structure is 0.2mm-0.4mm along the thickness direction of the first plate.

[0045] The maximum wall thickness of the fixing structure can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 1mm, etc. The maximum wall thickness of the fixing structure is preferably 0.7mm. The height of the fixing structure can be 0.2mm, 0.3mm, 0.4mm, etc. The height of the fixing structure is preferably 0.3mm. In this embodiment, when the maximum wall thickness and height of the fixing structure are within the above ranges, the welding strength of the waterproof and breathable membrane 20 can be guaranteed.

[0046] In some embodiments, refer to Figure 7 and Figure 9 The controller also includes a second housing 60, which is connected to the lower part of the first housing 10, and the first housing 10 and the second housing 60 form a receiving cavity; the controller also includes a circuit board 50, which is located in the receiving cavity and is thermally riveted to the first housing 10.

[0047] The second housing 60 can be a lower housing. The connection between the second housing 60 and the first housing 10 can be welding, such as laser welding, ultrasonic welding, hot plate welding, etc., to ensure the airtightness of the controller and to make the connection strength between the first housing 10 and the second housing 60 high, thereby improving the durability of the controller.

[0048] The first housing 10 may include a hot-riveting post. Before hot riveting, the diameter of the hot-riveting post can be 3.5 mm. After hot riveting, it forms a mushroom-shaped structure with a maximum outer diameter of 6.3 mm. In this embodiment, the circuit board 50 is connected to the first housing 10 by hot riveting, eliminating the need for screws and clips, and the connection performance is better than that of screw connections and clip connections.

[0049] It should be noted that, in the description of this embodiment, the upper and lower positions of the controller are consistent with the upper and lower positions of the vehicle.

[0050] In some embodiments, refer to Figure 7 and Figure 8 The controller also includes multiple connector pins 30, which are integrally injection molded with the first housing 10.

[0051] The first housing 10 includes a connector housing 18 and two second plates 17 facing each other along the length of the first housing 10. The two first plates 18 and the two second plates 17 form an inner cavity of the first housing 10. The connector housing 18 is disposed on the second plates 17, and the connector pins 30 are partially located inside the connector housing 18. There can be multiple connector housings 18, and each connector housing 18 corresponds to multiple connector pins 30.

[0052] The first housing 10 is made of plastic. Multiple connector pins 30 are integrally molded with the first housing 10 using an injection molding process. The integral injection molding process involves pre-placing multiple connector pins 30 into a mold, and then injecting molten plastic into the mold to form the first housing 10.

[0053] In this embodiment, multiple connector pins 30 and the first housing 10 are integrally injection molded, which reduces the height of the controller by at least 5mm, achieving weight reduction and space optimization, thus enabling the controller to be installed in narrow spaces inside a vehicle. Furthermore, compared to manufacturing multiple connectors separately and assembling them with the housing, this reduces the number of parts and assembly steps, improves structural strength, increases production efficiency, and lowers costs.

[0054] In some embodiments, the connector pin 30 has a fisheye portion, the circuit board 50 has a metallized through hole 51, the fisheye portion is interference-fitted with the metallized through hole 51, and the connector pin 30 forms an electrical connection with the hole wall of the metallized through hole 51 through the fisheye portion.

[0055] The connector pin 30 is L-shaped and includes a horizontal section and a vertical section. The horizontal section is located inside the connector housing 18, and the vertical section is located outside the connector housing 18. The vertical section has a fisheye portion. The fisheye portion of the connector pin 30 can be pressed into the metallized through-hole 51 using the Press-Fit physical crimping process to achieve an interference fit with the metallized through-hole 51. Compared with the method of soldering the connector pin 30 onto the circuit board 50, there is no soldering defect or thermal stress, and it can achieve automated production.

[0056] In some embodiments, refer to Figure 7 The controller also includes a pin fixing plate 40 and a circuit board 50. The pin fixing plate 40 is located between the first housing 10 and the circuit board 50. The pin fixing plate 40 has a limiting hole 41 for the connector pin 30 to pass through.

[0057] Specifically, the limiting hole 41 is used for the vertical section of the connector pin 30 to pass through. Multiple connector housings 18 are located on both sides of the controller along its length direction. Correspondingly, there are two pin fixing plates 40, with the length direction of the pin fixing plates 40 parallel to the width direction of the controller. The pin fixing plates 40 are connected to the first housing 10, and the connection method can be snap-fit. The limiting hole 41 is a through hole penetrating the pin fixing plate 40 along its thickness direction. The multiple limiting holes 41 on the pin fixing plate 40 correspond one-to-one with the multiple metallized through holes 51 on the circuit board 50. In this embodiment, the limiting holes 41 can limit the position of the connector pin 30 to ensure that the position of the connector pin 30 corresponds to the position of the metallized through hole 51 on the circuit board 50, thereby ensuring the connection effect between the connector pin 30 and the metallized through hole 51.

[0058] Secondly, embodiments of this application provide a vehicle including the controller provided in the first aspect. The vehicle can be a sedan, commercial vehicle, SUV, SUV, heavy truck, etc. The vehicle can be a new energy vehicle, such as a pure electric vehicle or a hybrid electric vehicle. The vehicle can also be a gasoline-powered vehicle.

[0059] Since the vehicle includes the aforementioned controller, it also possesses the beneficial effects of the aforementioned controller, which will not be elaborated upon here.
