Description

Technical Field

[0001] The present application relates to the technical field, and in particular to a controller housing, a controller and a vehicle. Background Art

[0002] The structure of automotive controllers is designed based on the controller's function, environment, assembly, and heat dissipation requirements. The structure of the controller, the shape and size of the casing are basically defined based on the function, environment, assembly, and space requirements. Under the requirements of a controller with limited space and high power, it is very difficult to take into account the appearance, heat dissipation, and functional practicality. Utility Model Content

[0003] In order to overcome the problems existing in the related art, the present application provides a controller housing, a controller and a vehicle.

[0004] According to a first aspect of an embodiment of the present application, a controller housing is provided, comprising: a surface of the controller housing having raised heat dissipation fins; the controller housing including a first surface, a label area for placing a label on the first surface, the heat dissipation fins being located away from the label area; on the first surface, areas on both sides of the label area along a first direction are designated as first areas; and areas on both sides of the label area along a second direction are designated as second areas; the first direction is perpendicular to the second direction; a plurality of heat dissipation fins are provided in both the first and second areas, and the distribution of the heat dissipation fins in the first area is different from the distribution of the heat dissipation fins in the second area. The heat dissipation fins provided in the controller housing can provide a larger heat dissipation surface by having a surface area greater than the cross-sectional area of ​​the heat dissipation fins when viewed from above, thereby increasing the heat dissipation area, speeding up heat dissipation, and achieving maximum heat dissipation for the controller. The heat dissipation fins on the first surface are distributed in the first and second areas, with the distribution of the heat dissipation fins in the first area being different from the distribution of the heat dissipation fins in the second area. This arrangement optimizes air flow and heat exchange efficiency, and can achieve higher heat dissipation efficiency when the air flow angles are different.

[0005] Furthermore, the heat dissipation fins located in the first area and the heat dissipation fins located in the second area are distributed differently, including at least one of the following: different shapes of the heat dissipation fins, different spacing between adjacent heat dissipation fins, and different extension directions of the heat dissipation fins. The different shapes, spacing, and extension directions of the heat dissipation fins can affect the flow of air between the heat dissipation fins, resulting in different heat dissipation areas and heat dissipation rates, thereby achieving a comprehensive balance for optimal heat dissipation efficiency.

[0006] Furthermore, each of the heat sink fins in the second region includes a first portion and a second portion. There are two second portions, each connected to the ends of the first portion. The first portion is parallel to the heat sink fins in the first region. The two second portions of the heat sink fins in the second region expand outward away from the label region. The second portion and the first portion form an angle greater than 30° and less than 90°. The heat sink fins in the second region are trapezoidal in shape. The provision of the second portion increases the total surface area of ​​the heat sink fins in the second region, resulting in a larger heat dissipation area and better heat dissipation.

[0007] Furthermore, the controller housing includes an upper housing and a lower housing that are fixedly connected; the lower housing includes mounting feet, the mounting feet are provided with mounting holes for fixing, and the mounting holes extend through the lower housing in the thickness direction; the upper housing is provided with a relief portion at one end near the mounting feet, which is recessed away from the mounting feet; the edge of the relief portion is provided with a heat dissipation fin; the surface area of ​​the heat dissipation fin located at the edge of the relief portion is greater than the surface area of ​​the heat dissipation fin away from the relief portion. The controller housing includes an upper housing and a lower housing, the mounting feet and mounting holes of the lower housing are used to fix the controller to the device to be installed, and the relief portion provided on the upper housing is used to leave space for fasteners installed in the mounting holes. At the same time, the edge of the relief portion is located on the heat dissipation fin, so that the surface area of ​​the heat dissipation fin located at the edge of the relief portion is greater than that of other heat dissipation fins, thereby obtaining a higher heat dissipation area and heat dissipation efficiency.

[0008] Furthermore, the controller housing includes an upper housing and a lower housing that are fixedly connected; the lower housing includes a second surface away from the upper housing, the second surface also being provided with the heat dissipation fins, the heat dissipation fins on the second surface being parallel to each other; the length of the heat dissipation fins located at the edge of the lower housing is less than the length of the heat dissipation fins located at the edge of the lower housing; and / or the lower housing further includes mounting feet; the plane on which the end surface of the mounting feet away from the first surface lies is a first plane, and the plane on which the end surface of the heat dissipation fins located at the second surface away from the first surface lies is a second plane, the first plane being farther away from the first surface than the second plane. The second surface is also provided with heat dissipation fins, so that the portion away from the first surface can also dissipate heat. Specifically, because the lower housing is a rounded cylinder, the length of the lower housing edge is less than the length of the lower housing middle portion, so the length of the heat dissipation fins located at the edge of the lower housing is less than the length of the heat dissipation fins located at the edge of the lower housing, thereby adapting to the shape of the lower housing. This arrangement ensures that, after installation, there is a gap between the heat dissipation fins located on the second surface and the mounting position, facilitating heat dissipation and improving heat dissipation performance.

[0009] Furthermore, the controller housing includes an upper housing and a lower housing that are fixedly connected. The lower housing is provided with a fixing hole for fixing the upper housing. The diameter of the fixing hole is less than or equal to the spacing between adjacent heat sink fins. The fixing hole is located between two adjacent heat sink fins. The fixing hole is used to accommodate a fixing member to securely connect the upper and lower housings. To ensure the heat dissipation area of ​​the heat sink fins, the fixing hole is located between the spaces between adjacent heat sink fins.

[0010] Furthermore, the controller housing includes an upper housing and a lower housing that are fixedly connected. A first stopper is provided on the surface of the upper housing near the lower housing, and a second stopper is provided on the surface of the lower housing near the upper housing, the second stopper being shaped to match the first stopper. The edge of the heat sink fin on the upper housing is spaced apart from the edge of the first stopper. The second stopper of the upper housing and the first stopper of the lower housing cooperate with each other to provide an embedded fit when the upper and lower housings are fixed together. This also facilitates user confirmation of installation direction and reduces the possibility of reverse installation.

[0011] Furthermore, the controller housing includes an upper housing and a lower housing that are fixedly connected. The upper housing is provided with a raised thickened portion, located at the edge of the upper housing facing the lower housing, and at least a portion of the heat sink fins located on the upper housing are connected to the thickened portion. The thickened portion is connected to the heat sink fins to provide stability in the direction of extension of the heat sink fins, thereby reducing the possibility of accidents such as the heat sink fins tilting due to collisions.

[0012] According to a second aspect of an embodiment of the present application, a controller is provided, including:

[0013] A control element and a controller housing as described above, wherein the control element is arranged in the controller housing.

[0014] According to a third aspect of an embodiment of the present application, a vehicle is provided, comprising:

[0015] A front fixing plate and the controller as described above, wherein the controller is fixed to the front fixing plate.

[0016] The technical solutions provided by the embodiments of the present application may have the following beneficial effects:

[0017] In the embodiments of the present application, the heat dissipation fins provided on the controller housing can increase the heat dissipation area, speed up heat dissipation, and achieve maximum heat dissipation for the controller. Furthermore, the heat dissipation fins on the first surface are distributed in a first region and a second region. The distribution of the heat dissipation fins in the first region is different from that in the second region. This arrangement optimizes air flow and heat exchange efficiency. When the air flow angles differ, higher heat dissipation efficiency can be achieved.

[0018] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0026] Next, the embodiments of the present application are described in detail.

[0027] The inventors noted the difficulty of balancing appearance, heat dissipation, and practical functionality in automotive controllers, which require a compact footprint and high power. Conventional designs are typically horizontal and vertical, and some areas lack heat dissipation design. This results in low overall heat dissipation efficiency, potentially insufficient to meet the cooling requirements during use. Therefore, the inventors proposed a controller that balances appearance, heat dissipation, and practical functionality. The controller includes a housing and a control element mounted within it.

[0028] like Figure 1 As shown, Figure 1 This is a structural diagram of the controller housing 1. The controller housing 1 comprises an upper housing 10 and a lower housing 20, which are connected and fixed to each other. Control components are secured within the space enclosed by the upper and lower housings 10, 20. These two housings limit and protect the control components within them.

[0029] During actual operation, the control components generate a lot of heat. To prevent the temperature from being too high and affecting the normal operation, the inventors have provided heat dissipation fins 30 on the controller housing 1 for dissipating heat.

[0030] Specifically, raised heat dissipation fins 30 are provided on the surface of the controller housing 1, so that the controller housing has a larger surface area in contact with the outside world, and a larger heat dissipation area is obtained through the larger surface area, thereby achieving a better heat dissipation effect.

[0031] like Figure 1 As shown, the controller housing 1 includes a first surface 100, on which a label area 110 for placing a label is provided. The heat dissipation fins 30 are disposed away from the label area 110. It should be noted that, as mentioned above, the heat dissipation fins 30 are disposed away from the label area 110, that is, the heat dissipation fins 30 are disposed outside the label area 110, and the area where the heat dissipation fins 30 are located does not overlap with the label area 110.

[0032] In the above configuration, the heat dissipation fins 30 are disposed outside the label area 110 to ensure that the label area 110 is a flat area for easy label attachment. In addition, the heat dissipation fins 30 can also dissipate heat from the first surface 100 .

[0033] Specifically, on the first surface 100, along the first direction X, the areas on both sides of the label area 110 are second areas 120. Along the second direction Y, the areas on both sides of the label area 110 are first areas 130. The first direction X is perpendicular to the second direction Y. In other words, the first direction X and the second direction Y divide the area of ​​the first surface 100 excluding the label area 110 into four sections. The number of second areas 120 and the number of first areas 130 are symmetrically distributed in the four sections.

[0034] A plurality of the heat dissipating fins 30 are provided in both the second area 120 and the first area 130 , and the distribution of the heat dissipating fins 30 located in the second area 120 is different from the distribution of the heat dissipating fins 30 located in the first area 130 . The heat dissipating fins 30 in the second area 120 and the heat dissipating fins 30 in the first area 130 have different distributions.

[0035] In the above arrangement, the heat dissipation fins 30 in the second area 120 and the heat dissipation fins 30 in the first area 130 are distributed differently, which not only accelerates heat dissipation by generating different air flow directions, but also can adapt to different usage environments and expand the scope of application.

[0036] Furthermore, the heat dissipating fins 30 located in the second area 120 are distributed differently from the heat dissipating fins 30 located in the first area 130, including at least one of the following: the shapes of the heat dissipating fins 30 are different, the spacing distances between adjacent heat dissipating fins 30 are different, and the extension directions of the heat dissipating fins 30 are different.

[0037] In this embodiment, the heat sink fins 30 in the second region 120 and the heat sink fins 30 in the first region 130 extend in different directions and have different shapes. The different extension directions break the convection bottleneck of air flow, improve heat transfer, and enhance heat dissipation efficiency. Furthermore, the different shapes provide a larger surface area, which results in higher heat dissipation efficiency.

[0038] like Figure 1 As shown, each heat sink fin 30 in the first region 130 includes a first portion 121 and a second portion 122. There are two second portions 122, each connected to the ends of the first portion 121. The first portion 121 is parallel to the heat sink fins 30 in the second region 120. The two second portions 122 of the heat sink fins 30 in the first region 130 expand outward in a direction away from the label region 110.

[0039] As configured above, the heat dissipation fins 30 in the first region 130 are distributed in a trapezoidal shape, which has a larger surface area and heat dissipation area, can achieve a better heat dissipation effect, and is aesthetically pleasing.

[0040] Specifically, an angle is formed between the second portion 122 and the first portion 121, the angle being greater than 30° and less than 90°. When the angle is greater than 30°, the length of the heat dissipation fins 30 in the first region 130 in the second direction Y can adapt to the size of the controller and will not be so long as to extend beyond or be cut off by the frame of the controller housing 1. When the angle is less than 90°, the heat dissipation fins 30 in the first region 130 can remain extended, facilitating air circulation to remove heat and improving heat dissipation efficiency.

[0041] like Figure 1 and Figure 2 As shown, the lower housing 20 includes mounting feet 21, each of which is provided with a mounting hole 22 for fixing. The mounting hole 22 extends through the lower housing 20 along its thickness. During the actual assembly process, the controller housing 1 needs to be fixed to the front fixing plate of the vehicle body. In this case, fasteners can be used to achieve a fixed connection between the controller housing 1 and the front fixing plate of the vehicle body. Specifically, the fasteners pass through the mounting hole 22 and the fixing holes in the front fixing plate of the vehicle body to achieve a fixed connection between the two. In other words, the mounting feet 21 are used to install the controller housing 1 in a designated position. When the controller housing 1 is fixedly installed using fasteners, the mounting hole 22 is used to accommodate the fasteners passing through the mounting feet 21.

[0042] The upper housing 10 is provided with a relief portion 11 at one end thereof close to the mounting foot 21 and recessed in a direction away from the mounting foot 21. The relief portion 11 is configured to accommodate a mounting tool for driving the fastener to move.

[0043] Furthermore, a heat sink 30 is disposed on an edge of the escape portion 11. The surface area of ​​the heat sink 30 located on the edge of the escape portion 11 is greater than the surface area of ​​the heat sink 30 located further away from the escape portion 11. The edge of the escape portion 11 is located on the heat sink 30, and the surface area of ​​the heat sink 30 located on the edge of the escape portion 11 is greater than that of other heat sink fins 30, thereby preventing heat from accumulating in corners (i.e., the edge), thereby improving the heat dissipation area and heat dissipation efficiency.

[0044] like Figure 2As shown, the lower housing 20 includes a second surface 200 away from the first surface 100. The second surface 200 is also provided with heat dissipation fins 30. The heat dissipation fins 30 located on the second surface 200 are parallel to each other. In addition, the length H1 of the heat dissipation fins 30' located at the edge of the lower housing 20 is less than the length H2 of the heat dissipation fins 30" away from the edge of the lower housing 20. The second surface 200 is also provided with heat dissipation fins 30, so that the portion away from the first surface 100 can also dissipate heat. Specifically, other components are arranged around the front fixing plate. By reducing the length of the heat dissipation fins 30' located at the edge, it is possible to avoid other surrounding components.

[0045] The plane where the end face of the mounting foot 21 away from the first surface 100 is located is the first plane 201, and the plane where the end face of the heat dissipation fin 30 located on the second surface 200 away from the first surface 100 is located is the second plane 202. The first plane 201 is farther away from the first surface than the second plane 202.

[0046] In the above configuration, mounting feet 21 protrude beyond the cooling fins 30. Because mounting feet 21 are secured to the front mounting plate via fasteners, the first flat surface of the mounting feet must align with the front mounting plate. This arrangement creates a gap between the cooling fins and the front mounting plate, facilitating heat dissipation and improving heat dissipation performance. This also prevents direct contact between the cooling fins and the front mounting plate, eliminating a rigid connection and extending product life. It also avoids unusual noises caused by collisions between the cooling fins and the front mounting plate during vehicle operation.

[0047] In this embodiment, the minimum distance between the first plane 201 and the second plane 202 is greater than or equal to 2 mm. The above configuration not only improves the heat dissipation capacity and increases the product life, but also effectively avoids abnormal noise caused by collision between the heat dissipation fins and the front fixing plate.

[0048] The lower shell 20 is provided with a fixing hole 24 for fixing the upper shell 10. Specifically, the fixing hole 24 can accommodate a fixing member for fixing the upper shell 10 and the lower shell 20.

[0049] In this embodiment, the fixing hole 24 spans across the locations of the two heat dissipation fins 30 located on the second surface 200 .

[0050] Of course, in other embodiments, in order not to affect the distribution of the upper heat sink fins 30, the following design can be made: the diameter of the fixing hole 24 is less than or equal to the spacing between adjacent heat sink fins 30, and the fixing hole 24 is arranged between two adjacent heat sink fins 30 to ensure the heat dissipation area of ​​the heat sink fins 30.

[0051] In this embodiment, each heat dissipation fin 30 has a height of 2 mm and a width of 1 mm, and a distance between two adjacent heat dissipation fins 30 is 2 mm.

[0052] Of course, in other embodiments, the height of the heat sink fins 30 may also be any other value between 1 mm and 3 mm. When the height of the heat sink fins 30 is greater than or equal to 1 mm, the heat dissipation rate of the heat sink fins 30 can be increased by increasing the surface area of ​​the heat sink fins 30, thereby achieving a better heat dissipation effect. Heat sink fins 30 that are more than 3 mm away from the second surface 200 have low heat dissipation efficiency. When the height of the heat sink fins 30 is less than or equal to 3 mm, production costs can be reduced and the average heat dissipation efficiency of the heat sink fins 30 can be improved.

[0053] The width of the heat sink fins 30 can also be any other value between 1 mm and 3 mm. When the width of the heat sink fins is greater than or equal to 0.5 mm, the heat dissipation rate of the heat sink fins can be increased by increasing the surface area of ​​the heat sink fins, thereby achieving better heat dissipation effect. If the width of the heat sink fins 30 is too large, the heat dissipation efficiency in the middle of the heat sink fins 30 will decrease. When the width of the heat sink fins 30 is less than or equal to 1.5 mm, a higher average heat dissipation efficiency can be achieved.

[0054] The distance between two adjacent heat sink fins 30 can also be any other value between 1 mm and 3 mm. A spacing of 1 mm or greater between adjacent heat sink fins can reduce the mutual influence of heat dissipation between adjacent heat sink fins. A spacing of 3 mm or less between adjacent heat sink fins is to increase the number of heat sink fins without affecting the heat dissipation efficiency of a single heat sink fin, thereby obtaining a larger total heat dissipation area and improving the overall heat dissipation efficiency.

[0055] Of course, different sizes of heat dissipation fins 30 can also be used. As long as the ratio of the height of the heat dissipation fins 30 to the width of the heat dissipation fins 30 is between 1:1 and 3:1, the best comprehensive heat dissipation efficiency can be obtained, that is, the highest heat dissipation efficiency can be obtained under the same material.

[0056] like Figure 3As shown, the upper housing 10 is provided with a first retaining member 12 on a surface adjacent to the lower housing 20, and the lower housing 20 is provided with a second retaining member 23 on a surface adjacent to the upper housing 10. The second retaining member 23 matches the shape of the first retaining member 12. The edge of the heat dissipating fins 30 on the upper housing 10 is spaced from the edge of the first retaining member 12, i.e., a certain gap distance d exists between the edge of the heat dissipating fins 30 on the upper housing 10 and the edge of the first retaining member 12. The second retaining member 23 of the upper housing 10 and the first retaining member 12 of the lower housing 20 cooperate with each other to provide a locking fit when securing the upper and lower housings 10, 20. This also facilitates user identification of the installation direction and reduces the possibility of reverse installation. In this embodiment, the first retaining member 12 is recessed and the second retaining member 23 is raised. However, in other embodiments, the first retaining member 12 may be raised and the second retaining member 23 recessed.

[0057] In addition, the upper housing 10 is provided with a raised thickened portion 13, located at the edge of the upper housing 10 facing the lower housing 20. At least a portion of the heat sink fins 30 located on the upper housing 10 is connected to the thickened portion 13. The thickened portion 13 is connected to the heat sink fins 30, providing a fixed position for the heat sink fins 30 in the extension direction, reducing the possibility of accidents such as the heat sink fins 30 tilting due to collisions. At the same time, the provision of the thickened portion 13 increases the contact area between the upper housing 10 and the lower housing 20, and increases the thickness at the contact point, thereby improving the stability of the connection between the upper housing 10 and the lower housing 20 and ensuring the structural strength of the upper housing 10.

[0058] Accordingly, the present application provides a vehicle, comprising a front fixing plate and the controller as described above, wherein the controller is fixed to the front fixing plate.
