electronic devices
[0001] This embodiment relates to an electronic device.
[0002]
[0003] While engine electrical systems (starting system, ignition system, charging system) and lighting systems are common electronic devices in automobiles, there is a recent trend toward most systems, including chassis electrical systems, becoming electrified as vehicles become more electronically controlled.
[0004] The external shape of the electronic device is formed by a housing. A plurality of electronic components for operation are arranged inside the housing. For example, the housing may have a shape with an open top surface, and a cover may be attached to the housing so that the space inside the housing is covered through the cover.
[0005] The housing and the cover may be joined by fastening means such as screws or by a hook method. Among these, the hook method is a joining method in which a protrusion is formed on one of the housing and the cover, and a hole is formed on the other that engages with said protrusion.
[0006] To seal the space within the housing, a sealing member may be placed between the housing and the cover. In this case, if a tolerance occurs in the physical fastening area between the housing and the cover, an overflow of the sealing liquid used to form the sealing member may occur, resulting in a problem of reduced sealing power of the space within the housing.
[0007]
[0008] The present invention provides an electronic device capable of improving the sealing power of the space within the housing and ensuring a robust connection with the cover.
[0009]
[0010] The electronic device according to the present embodiment comprises: a housing including a lower plate and a first side plate protruding upward from the lower plate; and a cover including an upper plate and a second side plate protruding downward from the upper plate. The device includes a sealing member disposed between the first side plate and the second side plate, wherein the first side plate comprises a first side plate, a second side plate disposed inside the first side plate, and a coupling groove disposed between the first side plate and the second side plate to which the sealing member and the second side plate are coupled, and the housing comprises a plurality of vertical portions protruding upward from the first side plate, a horizontal portion connecting the upper ends of the plurality of vertical portions, and a coupling portion in which a coupling hole is formed by the first surface of each of the plurality of vertical portions and the lower surface of the horizontal portion, and the cover protrudes from the outer surface of the second side plate and includes a projection that hook-couples to the coupling hole, and the vertical length from the bottom surface of the coupling groove to the upper surface of the first side plate is greater than or equal to the sum of the vertical lengths of the coupling hole and the horizontal portion.
[0011] The horizontal width of the above coupling hole may be at least twice the horizontal width of the above projection.
[0012] The horizontal width of the above coupling hole may be less than five times the horizontal width of the above projection.
[0013] Each of the above plurality of vertical sections includes a second surface opposite to the first surface, and the horizontal length between the second surfaces of the plurality of vertical sections may be at least 1.5 times the horizontal width of the coupling hole.
[0014] The horizontal length between the second surfaces of the plurality of vertical parts may be less than four times the horizontal width of the coupling hole.
[0015] The first side plate includes a first region and a second region whose upper surface is stepped downward from the upper surface of the first region, and the coupling portion may be disposed in the second region.
[0016] The above vertical part may be spaced apart from the above first region in the horizontal direction.
[0017] The horizontal width of the second region may be at least 1.2 times the horizontal length between the second surfaces of the plurality of vertical parts.
[0018] The vertical length of the above coupling hole may be 2 mm or more and 3.5 mm or less.
[0019] The sum of the vertical lengths of the coupling hole and the horizontal part may be at least 2 times and less than 5 times the vertical length of the coupling hole.
[0020]
[0021] Through this embodiment, the connection between the housing and the cover can be firmly established through the connecting part and the protrusion, and damage to the connecting part can be prevented during the hook connection process or in the connected state.
[0022] In addition, due to the shape of the second area and the joint part considering the placement area of the sealing member, the sealing member within the joint groove is firmly connected, thereby improving the sealing force of the space within the housing.

[0042] Referring to FIGS. 1 to 6, an electronic device (10) according to an embodiment of the present invention may include a housing (100), a cover (200), a substrate (300), and a sealing member (400).
[0043] The electronic device (10) may include a housing (100). The housing (100) may form the external shape of the electronic device (10) by being combined with a cover (200). A space (102) for arranging at least one electronic component may be formed within the housing (100). For example, a substrate (300) may be arranged in the space (102). The space (102) may be opened upward from the housing (100).
[0044] In detail, the housing (100) may be formed in a box shape with an open top surface. The housing (100) may include a bottom plate (110) and a first side plate (120). The bottom plate (110) may form the bottom surface of the electronic device (10). The top surface of the bottom plate (110) may form the bottom surface of the space (102). A protrusion (112) with a shape that protrudes upward from other areas may be disposed on the top surface of the bottom plate (110). Heat dissipation efficiency may be improved by increasing the surface area of the bottom plate (110) through the protrusion (112).
[0045] The first side plate (120) may have a shape that protrudes upward from the edge of the bottom plate (110). The outer surface of the first side plate (120) may form the side of the housing (100). The first side plate (120) may include two or more stepped regions with different cross-sectional areas. For example, the first side plate (120) may include a lower region having a first cross-sectional area and an upper region disposed on the lower region having a second cross-sectional area larger than the first cross-sectional area. The outer surface of the first side plate (120) may include a stepped region in the horizontal direction (X) formed by the upper region and the lower region. The inner surface of the space (102) formed by the inner surface of the first side plate (120) may include a stepped region in the horizontal direction (X) formed by the upper region and the lower region.
[0046] A connector outlet (190) may be disposed on the side of the housing (100). The connector outlet (190) may have a shape that protrudes outward from the outer surface of the first side plate (120). A space for disposing of a connector terminal may be formed inside the connector outlet (190). An external terminal is coupled to the connector outlet (190), and depending on the electrical and physical coupling between the external terminal and the connector terminal, power may be supplied to the electronic device (10), or an electrical signal for driving the electronic device (10) may be transmitted or received. One end of the connector terminal may be coupled to a substrate (300) disposed in the space (102) inside the housing (100).
[0047] A coupling groove (130) may be disposed on the upper surface of the first side plate (120). A sealing member (400), to be described later, may be disposed in the coupling groove (130). The coupling groove (130) may have a concave groove shape that extends downward from the upper surface of the first side plate (120) compared to other areas.
[0048] The coupling groove (130) may be formed by a plurality of side plates (122, 128). The first side plate (120) may include a first side plate (122) and a second side plate (128) disposed inside the first side plate (122). The lower region of the first side plate (120) is implemented through a single side plate, and at least a portion of the upper region of the first side plate (120) may be implemented in the first side plate (122) and the second side plate (128). The coupling groove (130) may be disposed between the first side plate (122) and the second side plate (128). The upper surface of the first side plate (122) and the upper surface of the second side plate (128) may be arranged to form the same height, but are not limited thereto, and the upper surface of the first side plate (122) may be arranged higher than the upper surface of the second side plate (128). When the sealing member (400) is coupled within the coupling groove (130), the sealing member (400) may be positioned between the inner surface of the first side plate (122) and the outer surface of the second side plate (128).
[0049] The first side plate (122) may include multiple regions with different vertical heights. Here, the vertical height may be the height protruding from the lower region of the first side plate (120). The upper surfaces of the multiple regions of the first side plate (122) may be arranged with a step difference in the vertical direction relative to each other. For example, the multiple regions of the first side plate (122) may include a first region (121), a second region (123), and a third region (124). The upper surface of the first region (121) may be positioned above the upper surface of the second region (123). The upper surface of the third region (124) may be positioned above the upper surface of the first region (121) and the upper surface of the second region (123). As shown in FIG. 5, the upper surface of the second region (123) may be positioned with a step difference downward from the upper surface of the second side plate (128).
[0050] As described above, the housing (100) may have a rectangular cross-sectional shape. For example, the housing (100) may include a plurality of short sides facing each other and a plurality of long sides connecting the cross-sections and facing each other. The length of each of the long sides may be longer than the length of each of the short sides. A first region (121) may be placed on each of the short sides. A second region (123) may be placed on each of the short sides. A third region (124) may be placed on each of the long sides. A plurality of second regions (123) may be placed based on a single short side. At least a portion of the third region (124) may be placed in a corner area connecting the short side and the long side.
[0051] The housing (100) may include a coupling portion (150). The coupling portion (150) may include a coupling hole (160) for hooking with the cover (200). The coupling portion (150) may be placed on the first side plate (120). The coupling portion (150) may have a shape that protrudes from the outer surface of the first side plate (120). The coupling portion (150) may have a shape in which at least a portion protrudes upward from the top of the first side plate (120). The coupling portion (150) may have a shape that protrudes upward from the first side plate (122). The coupling portion (150) may be placed in the second area (123) of the first side plate (122). The coupling portion (150) may be placed on the short side. For example, the connecting parts (150) may be provided in multiple numbers and arranged two at a time on the short side of the housing (100).
[0052] The connecting portion (150) may include a plurality of vertical portions (152) and a horizontal portion (156). The plurality of vertical portions (152) may be arranged parallel to each other. At least a portion of the plurality of vertical portions (152) may be arranged to overlap the first side plate (122) in the horizontal direction (X), and the remaining portion may be arranged to protrude upward from the first side plate (122) and offset from the first side plate (122) in the horizontal direction (X). The area of the vertical portion (152) that overlaps the first side plate (122) in the horizontal direction (X) may have a shape that protrudes outward from the outer surface of the first side plate (122). Each of the plurality of vertical portions (152) may have a predetermined width in the horizontal direction (X). A connecting hole (160) may be arranged between the plurality of vertical portions (152). The plurality of vertical portions (152) may be arranged in the second area (123). One of the plurality of vertical sections (152) may be spaced apart from the first area (121) by a predetermined distance in the horizontal direction (Y). Another of the plurality of vertical sections (152) may be spaced apart from the third area (124) by a predetermined distance in the horizontal direction (Y).
[0053] A horizontal section (156) may be arranged to connect a plurality of vertical sections (152). The horizontal section (156) may connect the upper ends of the plurality of vertical sections (152) to each other. Accordingly, a coupling hole (160) may be formed by the lower surface of the horizontal section (156) and the mutually opposing inner surfaces of the plurality of vertical sections (152). The horizontal section (156) may have a plate shape. A chamfered inclined surface (158) is arranged on the outer surface of the coupling section (150) connecting the vertical section (152) and the horizontal section (156), so that the vertical section (152) and the horizontal section (156) can be connected through the inclined surface (158). On the inner surface of the horizontal portion (156) facing the space (102) inside the housing (100), an inclined surface (156a, see FIG. 5) is arranged such that the width of the horizontal portion (156) increases as it goes downward, thereby easily guiding the connection with the protrusion (250) of the cover (200) to be described later.
[0054] The coupling hole (160) formed by the inner surface of a plurality of vertical sections (152) on the lower surface of the horizontal section (156) may have a hole shape that penetrates from the outer surface of the coupling section (150) to the inner surface. The upper surface of the second region (123) may form a part of the inner surface of the coupling hole (160).
[0055] The material of the housing (100) may be plastic.
[0056] A cover (200) can be attached to a housing (100). By attaching the cover (200), the upper surface of the space (102) of the housing (100) can be covered. The cover (200) may include an upper plate (210) and a second side plate (220). The upper plate (210) may form the upper surface of the electronic device (10). The cross-sectional area of the upper plate (210) may be larger than the cross-sectional area of the space (102) within the housing (100).
[0057]
[0058] *43 The cover (200) may include an electronic device coupling part (290) having a shape that protrudes outward from the side of the upper plate (210). The electronic device coupling part (290) may be provided in multiple numbers and arranged opposite each other with respect to the center of the cover (200). The electronic device coupling part (290) includes a screw hole (292), and the electronic device (10) may be coupled to the coupling area by fastening a screw within the screw hole (292). The electronic device coupling part (290) may be placed between multiple coupling parts (150). The electronic device coupling part (290) may be placed on the first area (121) of the housing (100).
[0059] The second side plate (220) may have a shape that protrudes downward from the edge of the top plate (210). The second side plate (220) may be positioned vertically with respect to the top plate (210). At least a portion of the second side plate (220) may be coupled within the coupling groove (130) of the housing (100). As shown in FIG. 5, when the second side plate (220) is coupled to the coupling groove (130), at least a portion of the second side plate (220) may be positioned to overlap the first side plate (122) and the second side plate (128) in the horizontal direction (X).
[0060] The cover (200) may include a projection (250) for hook coupling with the housing (100). The projection (250) may be hook-coupled with the coupling portion (150). The projection (250) may have a shape that protrudes outward in the horizontal direction (X) from the outer surface of the second side plate (220). The projection (250) may be coupled to the coupling hole (160).
[0061] A catch surface (254) that engages with the lower surface of the horizontal portion (156) of the coupling portion (150) may be disposed on the upper surface of the projection (250). The catch surface (254) may be disposed perpendicular to the outer surface of the second side plate (220). An inclined surface (252) having a shape in which the height of the horizontal direction (X) protrusion from the second side plate (220) decreases as it goes downward may be disposed on the lower surface of the projection (250). Accordingly, during the coupling process between the projection (250) and the coupling portion (150), the projection (250) may be guided toward the coupling hole (160) through the inclined surface (252).
[0062] The electronic device (10) may include a sealing member (400). The sealing member (400) may be positioned between the first side plate (120) and the second side plate (220). The sealing member (400) may be positioned within the coupling groove (130). The sealing member (400) may be coupled with the second side plate (220). The sealing member (400) may be positioned to cover the inner surface, lower surface, and a portion of the outer surface of the second side plate (220). The sealing member (400) may be an area where a liquid sealant has cured. Through the sealing member (400), external foreign substances containing moisture may be prevented from entering the space (102) inside the housing (100) through the space between the housing (100) and the cover (200). The sealing member (400) has adhesive strength, and accordingly, the connection between the housing (100) and the cover (200) can be made more firmly.
[0063] Below, the hook coupling structure of the housing (100) and the cover (200) will be described in more detail.
[0064] As illustrated in FIG. 6, the coupling portion (150) of the housing (100) may generate maximum stress at the upper end of the second region (123), the connecting region of the vertical portion (152), and the horizontal center of the horizontal portion (156) according to the hook coupling with the projection (250). Accordingly, the coupling portion (150) within the housing (100) and the projection (250) of the cover (200) according to the embodiment may have the following structure and shape.
[0065] As illustrated in FIGS. 3 and 4, the horizontal width (L1) of the coupling hole (160) may be at least twice the horizontal width (L0) of the protrusion (250). If the horizontal width (L1) of the coupling hole (160) is less than twice the horizontal width (L0) of the protrusion (250), damage to the coupling part (150) may occur during the hook coupling process due to an increase in the pressurization force of the protrusion (250) within the coupling hole (160). Therefore, by forming the horizontal width (L1) of the coupling hole (160) to be at least twice the horizontal width (L0) of the protrusion (250), damage to the coupling part (150) due to coupling of the protrusion (250) within the coupling hole (160) can be prevented.
[0066] However, if the horizontal width (L0) of the protrusion (250) has a range below the set range, there is a concern that the bonding force with the coupling part (150) may not be sufficient. Therefore, the horizontal width (L0) of the protrusion (250) may be within the range of 4 mm or more and 6 mm or less, and may be less than or equal to 1 / 2 of the horizontal width (L1) of the coupling hole (160).
[0067] Additionally, if the horizontal width (L1) of the coupling hole (160) is excessively large compared to the horizontal width (L0) of the protrusion (250), there is a risk that the sealing member (400) will be exposed in the exposed area of the coupling hole (160) excluding the placement area of the protrusion (250). Therefore, the horizontal width (L1) of the coupling hole (160) may be less than five times the horizontal width (L0) of the protrusion (250).
[0068] When the side surface of the vertical part (152) that forms the inner surface of the coupling hole (160) is called the first surface and the side opposite to the first surface is called the second surface, the horizontal (Y) length (L2) between the second surfaces of the plurality of vertical parts (152) based on a single coupling part (150) may be at least 1.5 times the horizontal width (L1) of the coupling hole (160). If the horizontal (Y) length (L2) between the second surfaces of the plurality of vertical parts (152) is less than 1.5 times the horizontal width (L1) of the coupling hole (160), the horizontal (Y) width of the vertical part (152) itself is insufficient, and damage to the vertical part (152) may occur during the coupling process with the protrusion (250) or in the state of coupling with the protrusion (250). However, if the horizontal width of the vertical part (152) is excessively large, the connection with the protrusion (250) is not easy due to the increase in rigidity, so the horizontal length (Y) (L2) between the second surfaces of the multiple vertical parts (152) may be less than four times the horizontal width (L1) of the coupling hole (160).
[0069] The horizontal (Y) width (L3) of the second area (123), which is the placement area of the joint part (150), may be at least 1.2 times the horizontal (Y) length (L2) between the second surfaces of the plurality of vertical parts (152). If the spacing between the second surface of the vertical part (152) and the first area (121), or between the second surface of the vertical part (152) and the third area (124), is insufficient, there is a risk of damage to the joint part (150) due to contact occurring between the vertical part (152) and the first area (121), or between the vertical part (152) and the third area (124), during the joining process of the protrusion (250) within the joint part (150). Accordingly, in the embodiment, in order to secure a horizontal (Y) distance between the vertical section (152) and the first area (121), and between the vertical section (152) and the third area (124), the horizontal (Y) width (L3) of the second area (123) may be at least 1.2 times the horizontal (Y) length (L2) between the second surfaces of the plurality of vertical sections (152).
[0070] The vertical direction (Z) length (H0) of the coupling hole (160) may be 2 mm or more and 3.5 mm or less. If the vertical direction (Z) length (H0) of the coupling hole (160) is less than 2 mm, the engagement area with the protrusion (250) inside the coupling hole (160) is insufficient, so the coupling force between the housing (100) and the cover (200) may be reduced. However, if the vertical direction (Z) length (H0) of the coupling hole (160) exceeds 3.5 mm, the vertical direction (Z) length of the protrusion (250) also increases, thereby increasing the possibility of damage to the coupling part (150) and causing the sealing member (400) to detach through the coupling hole (160).
[0071] The sum of the lengths (H1) in the vertical direction (Z) of the coupling hole (160) and the horizontal part (156) may be more than twice the length (H0) in the vertical direction (Z) of the coupling hole (160). If the sum of the lengths (H1) in the vertical direction (Z) of the coupling hole (160) and the horizontal part (156) is less than twice the length (H0) in the vertical direction (Z) of the coupling hole (160), there is a possibility that the coupling part (150) may be damaged due to a decrease in the durability of the horizontal part (156) itself caused by a reduction in the width (Z) in the vertical direction of the horizontal part (156). However, if the sum of the lengths (H1) in the vertical direction (Z) of the coupling hole (160) and the horizontal part (156) is excessively large, the connection process with the protrusion (250) is not easy due to the increase in rigidity of the horizontal part (156) itself, so the sum of the lengths (H1) in the vertical direction (Z) of the coupling hole (160) and the horizontal part (156) may be less than 5 times the length (H0) in the vertical direction (Z) of the coupling hole (160).
[0072] As illustrated in FIG. 5, the vertical length (H2) from the bottom surface of the coupling groove (130) to the top surface of the second area (123) may be greater than or equal to the sum of the lengths in the vertical direction (Z) of the coupling hole (160) and the horizontal section (156) (H1). If the vertical length (H2) from the bottom surface of the coupling groove (130) to the top surface of the second area (123) is less than the sum of the lengths in the vertical direction (Z) of the coupling hole (160) and the horizontal section (156) (H1), the sealant for forming the sealing member (400) may overflow beyond the top of the second area (123). Therefore, due to the vertical height (Z) of the second area (123) described above, a dam function for forming the sealing member (400) within the coupling groove (130) can be implemented through the second area (123).
[0073] However, if the vertical length (H2) from the bottom surface of the coupling groove (130) to the top surface of the second region (123) is excessively large, the hook coupling force may be weakened by the reduction in the vertical width (Z) of the coupling hole (160). Therefore, the vertical length (H2) from the bottom surface of the coupling groove (130) to the top surface of the second region (123) may be 1.5 times or less of the sum of the lengths (H1) in the vertical direction (Z) of the coupling hole (160) and the horizontal part (156).
[0074] According to the embodiment, the connection between the housing and the cover can be firmly formed through the connecting part and the protrusion, and damage to the connecting part can be prevented during the hook connection process or in the connected state.
[0075] In addition, due to the shape of the second area and the joint part considering the placement area of the sealing member, the sealing member within the joint groove is firmly connected, thereby improving the sealing force of the space within the housing.
[0076] In the foregoing, although all components constituting an embodiment of the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways. Furthermore, terms such as "include," "constitute," or "have" described above, unless specifically stated otherwise, mean that the relevant component may be inherent; thus, they should be interpreted as allowing for the inclusion of additional components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains, unless otherwise defined. Terms commonly used, such as those defined in advance, should be interpreted in accordance with their meaning in the context of the relevant technology and should not be interpreted in an ideal or overly formal sense unless explicitly defined in the present invention.
[0077] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
