Description

Technical Field

[0001] The present application relates to the technical field of structural protection, and in particular to a protective structure and a vehicle-mounted control box. Background Art

[0002] To ensure balanced air pressure inside and outside the control box (MCU, DCDC, OBC, etc.), new energy vehicle onboard control boxes typically require at least one vent valve. This precision component, often made of plastic, can be easily damaged during product distribution if not properly protected. This can disrupt the pressure balance inside and outside the control box, leading to numerous product failures.

[0003] In the related art, although some vent valves are provided with a protective structure, while protecting the vent valve, when the car is exposed to rain or soaked in water, water will accumulate in the protective structure. Long-term accumulation of water may cause the vent valve seal to fail, and may also corrode the control box housing, and the control box will also face the risk of failure. Utility Model Content

[0004] Based on this, it is necessary to provide a protective structure and a vehicle-mounted control box that can protect the vent valve and reduce water accumulation in order to address the above-mentioned problems.

[0005] A protective structure is used to protect a breathable valve arranged on the installation surface of a vehicle-mounted control box. The protective structure includes a protective wall, which is arranged around the breathable valve and has a drainage portion formed thereon for draining water outward.

[0006] In one embodiment, the drainage portion is constructed as a drainage outlet, and the drainage outlet is provided through the protective wall from a side facing the ventilation valve to a side facing away from the ventilation valve.

[0007] In one embodiment, the end of the protective wall connected to the mounting surface is the bottom end, and the end away from the mounting surface is the top end, and the drain outlet extends from the bottom end of the protective wall to the top end.

[0008] In one embodiment, the protective structure further includes an outer protective wall, and the outer protective wall is spaced apart and arranged on the outer side of the protective wall away from the breathable valve.

[0009] In one embodiment, the outer protective wall is arranged in a one-to-one correspondence with the drain outlet.

[0010] In one embodiment, at least a portion of the outer protective wall has a guide groove on a side facing the drain outlet, and the guide groove is connected to an outer edge of the outer protective wall away from the installation surface.

[0011] In one embodiment, the surface of the outer protective wall facing the guard wall is configured to be inclined away from the guard wall in a direction away from the installation surface.

[0012] In one embodiment, the protective structure further includes a second reinforcing rib, and the second reinforcing rib is connected between the mounting surface and the outer protective wall.

[0013] In one embodiment, the protective wall comprises at least two sections of sub-protective walls, and all of the sub-protective walls are sequentially arranged around the breathable valve;

[0014] Wherein, the drainage outlet is formed between each two adjacent sub-protection walls.

[0015] In one embodiment, the surface of the protective wall facing the breathable valve is configured to be inclined in a direction away from the mounting surface and away from the breathable valve.

[0016] In one embodiment, the height of the protective wall relative to the installation surface is higher than the height of the air valve relative to the installation surface.

[0017] In one embodiment, the protective structure further includes a first reinforcing rib, wherein the first reinforcing rib connects the mounting surface and the protective wall.

[0018] A vehicle-mounted control box comprises a vent valve and the protective structure as described above.

[0019] The aforementioned protective structure and onboard control box, while surrounding and protecting the vent valve with a protective wall, also include a drainage portion capable of draining water from within the protective structure. This protects the vent valve while also preventing water from accumulating in the protective structure after the vehicle is exposed to rain or water, thereby reducing the risk of vent valve seal failure and onboard control box failure.

[0034] See also Figures 1 to 3The protective structure 10 provided in one embodiment of the present application is used to protect the breathable valve 30 provided on the mounting surface 51 of the vehicle-mounted control box 100, and includes a protective wall 11. The protective wall 11 is provided around the breathable valve 30 and has a drainage portion 112 formed thereon for draining water outward.

[0035] The air valve 30 provides both ventilation and waterproofing, maintaining pressure balance inside and outside the vehicle control box 100 during normal operation. The air valve 30 is mounted on the housing 50 of the vehicle control box 100, which is provided with a mounting hole for the air valve 30. The surface of the vehicle control box 100 where the air valve 30 is mounted is also known as the mounting surface 51 of the air valve 30. The protective wall 11 is also located on this mounting surface 51 and surrounds the air valve 30. As will be understood, the protective wall 11 has a bottom end connected to the mounting surface 51 and a top end away from the mounting surface 51.

[0036] The protective wall 11 can be spaced apart from the air valve 30 and can be manufactured as a whole with the vehicle control box 100 by die casting or injection molding. The side facing the air valve 30 can also be called the inner wall 115 of the air valve 30, and the side facing away from the air valve 30 can also be called the outer wall 117 of the air valve 30.

[0037] The drainage portion 112 drains water from the inner side of the protective wall 11 to the outer side of the protective wall 11. The inner side of the protective wall 11 is the side facing the vent valve 30. The outer side of the protective wall 11 includes the side facing away from the vent valve 30 and any areas not enclosed by the protective wall 11, such as the top. In other words, the drainage portion 112 drains water away from the vent valve 30.

[0038] The protective structure 10, while surrounding and protecting the vent valve 30 with the protective wall 11, also includes a drainage portion 112, which can drain water from the interior of the protective structure 10. This protects the vent valve 30 while also preventing water from accumulating in the protective structure 10 after the vehicle is exposed to rain or flooding, thereby reducing the risk of sealing failure of the vent valve 30 and the resulting failure of the onboard control box 100.

[0039] In some embodiments, the drainage portion 112 is configured as a drainage port 113 that penetrates from the side of the protective wall 11 facing the ventilation valve 30 to the side facing away from the ventilation valve 30. In other words, the drainage port 113 penetrates and connects the inner and outer sides of the protective wall 11.

[0040] In this way, the accumulated water inside the protective wall 11 can directly pass through the protective wall 11 through the drainage port 113 and be discharged to the outside thereof.

[0041] In some embodiments, the drain port 113 extends from the bottom end to the top end of the protective wall 11. In this way, the drain port 113 can fully cover the entire protective wall 11, reducing dead corners where water accumulates.

[0042] Specifically, the drain opening 113 extends from the bottom to the top of the protective wall 11. In other words, the protective wall 11 is discontinuously formed with the drain opening 113 in the direction surrounding the vent valve 30. That is, the protective wall 11 is discontinuous in the direction surrounding the vent valve 30, and the discontinuity forms the drain opening 113. There is at least one drain opening 113.

[0043] In this way, the drainage port 113 is formed in a simple manner and can fully cover the entire protection wall 11 in the height direction of the protection wall 11, which is conducive to sufficient drainage of the protection structure 10 and prevents water accumulation.

[0044] Furthermore, the protective wall 11 includes at least two sections of sub-protective walls 111, and the sub-protective walls 111 are sequentially arranged around the breathable valve 30. A drainage port 113 is formed between each two adjacent sub-protective walls 111.

[0045] In other words, the protective wall 11 is broken in the direction surrounding the vent valve 30 to form at least two sections of sub-protective walls 111. The break is the gap between adjacent sub-protective walls 111, which is the drain opening 113. Accordingly, the number of drain openings 113 is at least two. From another perspective, the protective wall 11 is interrupted to form at least two drain openings 113, which divide the protective wall 11 into at least two sections of sub-protective walls 111. The number of sub-protective walls 111 is the same. Each section of sub-protective walls 111 can be of the same shape and size, and the drain openings 113 are evenly spaced.

[0046] Thus, on the one hand, during the manufacture of the protective wall 11, the sub-protective walls 111 can be formed separately by die-casting or injection molding. After all the sub-protective walls 111 are manufactured, the protective wall 11 having the drain openings 113 is obtained. On the other hand, the provision of multiple drain openings 113 can improve the drainage capacity of the protective wall 11, allowing the protective structure 10 to drain water at different angles.

[0047] In some embodiments, in a direction surrounding the vent valve 30 , the ratio of the total length of the protective wall 11 to the sum of the widths of all the drain openings 113 is 10:1-2:1.

[0048] The total length of the protective wall 11, i.e., the extended length of the entire protective wall 11, includes the total extended length of all sub-protective walls 111 and the total width of all drainage openings 113. The ratio of the extended length of a single sub-protective wall 111 to the width of a single drainage opening 113 can be 10:1 to 1:1, and specifically can be 10:1, 7:1, 4:1, 1:1, etc.

[0049] It is understood that, provided the width of the drain outlet 113 remains unchanged, the greater the number of sub-protective walls 111 in the protective wall 11, the more the protective wall 11 can be in the form of a grid, and the smaller the ratio of the total length of the protective wall 11 to the width of the drain outlet 113. When the number of sub-protective walls 111 is sufficient, the ratio of the total length of the protective wall 11 to the width of the drain outlet 113 can also be less than 2:1, and can specifically be 1.5:1, 1:1, 0.5:1, etc., without specific limitation herein.

[0050] In this way, the protective wall 11 can fully protect the breathable valve 30 under the cavity that meets the drainage requirements.

[0051] In some embodiments, the width of each drain port 113 is no greater than 1 cm, and may specifically be, but not limited to, 1 cm, 8 mm, 6 mm, 4 mm, etc., which is not specifically limited here.

[0052] Within this width range, the drain outlet 113 can effectively drain water, meet the drainage needs of the protective structure 10 in its use environment, reduce the occurrence of water accumulation, and prevent the drain outlet 113 from being too large, meet the protection needs of the protective structure 10 in its use environment, and fully protect the air valve 30.

[0053] It is understood that in other embodiments, the drainage portion 112 may also be constructed as a water channel, a water guide slope, etc. The drainage port 113 may also be a through hole constructed on the protective wall 11, etc., as long as it can achieve the drainage function inside and outside the protective structure 10, and is not specifically limited here.

[0054] In some embodiments, the protective wall 11 surrounds the breathable valve 30 in a circular shape, and the sub-protective walls 111 are all arc-shaped and can be uniformly arranged with equal lengths.

[0055] The overall outline of the protective wall 11 is a circle, and its total length is the circumference of the circle. Each section of the sub-protective wall 111 formed discontinuously by the protective wall 11 is a part of the circle, in the shape of an arc, and the curvature can be consistent.

[0056] In this way, the circular protective wall 11 can better fit the shape of the air valve 30 and fully protect the air valve 30.

[0057] In some embodiments, the protective wall 11 includes at least four drain openings 113. The number of drain openings 113 can be, but is not limited to, 4, 5, 6, etc. The protective wall 11 can have four drain openings 113, facing in four directions: up, down, left, and right.

[0058] Considering that the vehicle-mounted control box 100 is generally in the shape of a cube or a rectangular parallelepiped, one side thereof serves as the mounting surface 51, allowing for at least four possible placement angles for the protective structure 10. When configuring the protective structure 10, a drainage opening 113 is formed at the bottom of the protective wall 11 at each placement angle. In other words, the protective wall 11 includes at least the same number of drainage openings 113 as the side surfaces of the vehicle-mounted control box 100.

[0059] In this way, the protective structure 10 can fully exert its drainage effect at different angles, which helps to solve the problem of water accumulation at certain angles.

[0060] In some embodiments, the surface of the protective wall 11 facing the breathable valve 30 is configured to be inclined in a direction away from the mounting surface 51 and away from the breathable valve 30 .

[0061] In other words, the surface of the protective wall 11 facing the vent valve 30 is configured to gradually face away from the vent valve 30 as it moves away from the mounting surface 51. Specifically, the surface of the protective wall 11 facing the vent valve 30, i.e., the inner wall 115 of the protective wall 11, can be configured to extend in an inclined or arcuate manner as it moves away from the mounting surface 51 and away from the vent valve 30. When the protective wall 11 circularly surrounds the vent valve 30, the inner wall 115 of the protective wall 11 has a trumpet-like shape.

[0062] In this way, the moisture in the protective structure 10 can not only be discharged from the drain port 113 , but can also easily flow along the inner wall 115 of the protective wall 11 under the action of gravity and be discharged to the outside.

[0063] In some embodiments, the protective structure 10 further includes a first reinforcing rib 13, which connects the mounting surface 51 and the protective wall 11. The first reinforcing rib 13 supports the protective wall 11, and each sub-wall 111 may be provided with a first reinforcing rib 13. The first reinforcing rib 13 may be located on the outer periphery of the protective wall 11 and connect the mounting surface 51 to the outer wall 117 of the protective wall 11. The first reinforcing rib 13 is a contoured reinforcing rib.

[0064] Thus, the first reinforcing rib 13 can improve the structural strength, rigidity, and stability of the protective wall 11, reduce the probability of damage from collisions, and thus improve its protection performance for the breathable valve 30. In addition, the design of the first reinforcing rib 13 can also increase the flow channel during die casting and injection molding, facilitating the molding process.

[0065] In some embodiments, the height of the protective wall 11 relative to the installation surface 51 is higher than the height of the air valve 30 relative to the installation surface 51 .

[0066] In this way, the protective wall 11 can protect the vent valve 30 from a higher angle, preventing the vent valve 30 from being damaged by an impact from the top of the protective wall 11 .

[0067] In some embodiments, the protective structure 10 may further include a protective cap, which is disposed on the top of the protective wall 11 and covers the air valve 30 to protect the air valve 30 .

[0068] In some embodiments, the protective structure 10 includes at least two layers of protective walls 11 , and the drainage openings 113 of adjacent protective walls 11 are staggered.

[0069] All protective walls 11 are spaced apart in a direction away from the vent valve 30. For two adjacent layers of protective walls 11, one is located on the inner layer, and the other on the outer layer. The drain openings 113 of adjacent protective walls 11 are at least partially staggered, ensuring that the vent valve 30 cannot be viewed inward through the drain opening 113 of the outermost protective wall 11. In other words, along the radial projection of the vent valve 30, the drain opening 113 of one protective wall 11 is completely covered by the sub-protective walls 111 of the remaining protective walls 11. For a protective structure 10 with two layers of protective walls 11, the drain openings 113 of the two layers are completely staggered.

[0070] In this way, the protective structure 10 can drain water through the drain port 113 while completely surrounding and protecting the vent valve 30 through the layers of protective walls 11 .

[0071] See also Figures 4 to 6 In some embodiments, the protective structure 10 further includes an outer protective wall 70 , which is spaced apart and arranged on the outer side of the protective wall 11 away from the breathable valve 30 .

[0072] It can be understood that, in the direction away from the breathable valve 30 , the outer protective wall 70 and the protective wall 11 are spaced apart to form a double-layer spacer structure.

[0073] In this way, the outer protective wall 70 can provide further protection on the outer layer of the protective wall 11 , thereby achieving double-layer protection for the breathable valve 30 .

[0074] In some embodiments, the outer protective wall 70 and the drain outlet 113 are arranged in a one-to-one correspondence.

[0075] In other words, the number of protective structures 10 matches the number of drain openings 113, and each drain opening 113 is oriented in a corresponding direction with an outer protective wall 11. Specifically, the protective wall 11 may have four drain openings 113, facing upward, downward, leftward, and rightward directions. Accordingly, the protective structure 10 may include four outer protective walls 70, located in the upward, downward, leftward, and rightward directions.

[0076] In this way, the outer protective wall 70 can block the drain port 113 without affecting the drainage of the drain port 113, so as to prevent small wires, rods and other foreign objects from entering through the drain port 113 of the protective wall 11 and damaging the air valve 30, thereby protecting the air valve 30 360 degrees.

[0077] Furthermore, at least a portion of the outer protective wall 70 has a diversion groove 71 on a side facing the drain outlet 113 , and the diversion groove 71 is connected to the outer edge of the outer protective wall 70 away from the installation surface 51 .

[0078] The diversion groove 71 communicates with the outer edge of the end of the outer protective wall 70 away from the mounting surface 51. This means that the diversion groove 71 extends and penetrates the end of the outer protective wall 70 away from the mounting surface 51, allowing water to flow along the diversion groove 71 to the end of the outer protective wall 70 and out. Each outer protective wall 70 can be arc-shaped, with the diversion groove 71 located at the bottom of the arc and extending from the mounting surface 51 to the end of the outer protective wall 70. Furthermore, the diversion groove 71 can be configured to be inclined away from the protective wall 11 in a direction away from the mounting surface 51.

[0079] Preferably, among all the outer protective walls 70 , at least the outer protective walls 70 corresponding to the downward drainage outlets 113 are constructed with diversion grooves 71 .

[0080] In this way, water falling into the outer protective wall 70 from the drain port 113 can flow into the guide groove 71 and, under the guidance of the guide groove 71, flow out from the end of the outer protective wall 70, avoiding a small amount of accumulated water forming a water film remaining on the inner side of the outer protective wall 70.

[0081] In some embodiments, the surface of the outer protective wall 70 facing the protective wall 11 is configured to be inclined away from the protective wall 11 in a direction away from the installation surface 51 .

[0082] In other words, the surface of the outer protective wall 70 facing the protective wall 11 is configured to gradually diverge from the protective wall 11 as it moves away from the mounting surface 51. Specifically, the surface of the outer protective wall 70 facing the protective wall 11, i.e., the inner surface of the outer protective wall 70, can be configured to extend in an inclined or arcuate manner as it moves away from the mounting surface 51 and away from the protective wall 11. When the protective wall 11 circularly surrounds the vent valve 30, the inner surface of the entire outer protective wall 70 forms a trumpet shape.

[0083] In this way, the water falling upward on the outer protective wall 70 can flow along the inner surface of the outer protective wall 70 under the action of gravity and be discharged outward.

[0084] In some embodiments, the protective structure 10 further includes a second reinforcing rib 73 , which connects the mounting surface 51 and the outer protective wall 70 .

[0085] The second reinforcing rib 73 is a contour-type reinforcing rib. On the premise that the second reinforcing rib 73 is provided between the mounting surface 51 and the outer protective wall 70 , the first reinforcing rib 13 may be omitted from the mounting surface 51 and the protective wall 11 .

[0086] Thus, the second reinforcing ribs 73 can improve the structural strength, rigidity, and stability of the outer protective wall 70, reduce the probability of damage from collisions, and thus improve its protection of the breathable valve 30. In addition, the design of the second reinforcing ribs 73 can also increase the flow path during die casting and injection molding, facilitating the molding process.

[0087] The protective structure 10 comprises a protective wall 11, which is interrupted to form at least four sub-walls 111. The interruptions form drains 113 for draining accumulated water. The protective wall 11 has at least four drainage openings 113 oriented vertically, horizontally, and vertically, enabling the protective structure 10 to effectively drain water regardless of the orientation of the vehicle control box 100. Reinforcing ribs are provided at each sub-wall 111 to enhance its structural strength and facilitate molding during manufacturing. The inner wall 115 of the protective wall 11 is shaped like a trumpet to facilitate the drainage of water along the inner wall 115 under the action of gravity. In addition, an outer protective wall 70 is provided on the outside of the protective wall 11. The outer protective wall 70 is arranged in a one-to-one correspondence with the drain outlet 113, and has a guide groove 71 facing the drain outlet 113, which can prevent small wires, rods and other foreign objects from entering through the drain outlet 113 of the protective wall 11 and damaging the air valve 30, and guide the water discharged from the drain outlet 113 to be discharged outward through the guide groove 71.

[0088] In this way, the protective structure 10 has the following advantages: 1. Good protection effect: 360° double-layer all-round protective ventilation valve 30 avoids blind spots in protection; 2. Reduces water accumulation: drain outlets 113 are formed in the upper, lower, left and right directions of the protective wall 11. The drain outlets 113 can guide the accumulated water to flow out. It has a trumpet-shaped inclined inner wall 115 structure. Rainwater will flow down under gravity and cannot be retained. The diversion groove 71 of the outer protective wall 70 makes it easier to divert the accumulated water to the outside, avoiding a small amount of accumulated water from forming a water film; 3. High reliability: the outer side surface of the outer protective wall 70 is evenly and symmetrically arranged with second reinforcing ribs 73, which improve the strength, rigidity and stability of the outer protective wall 70 and prevent the protective structure 10 from being damaged; 4. Good processability: the reinforcing ribs can increase the number of flow channels during die-casting, which is beneficial to die-casting; 5. Simple structure.

[0089] The present application also provides a vehicle-mounted control box 100 , comprising the above-mentioned protective structure 10 .

[0090] It is understandable that, in order to realize its normal function, the vehicle control box 100 may include a housing 50 and a control unit disposed in the housing 50. The housing 50 may include a box body 53 and a box cover 55, wherein the box body 53 has a fixing ear 531, and the box cover 55 is used to close the box body 53.

[0091] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-described embodiments merely represent several implementation methods of the present application.
