Description

Technical Field

[0001] The present invention belongs to the technical field of light-emitting devices, and in particular relates to a light-emitting module based on side interference reinforcement. Background Art

[0002] The light-emitting module is a key component widely used in electronic devices such as LED lamps. However, as the power of the module increases, the heat dissipation problem becomes increasingly prominent. At present, cast heat sinks are generally used to improve the heat dissipation performance of the light-emitting module. However, due to the draft angle of the fins of the cast heat sink, the fin length of the cast heat sink is small and the fin spacing is large, which cannot effectively increase the heat dissipation area, limiting the improvement of the heat dissipation effect.

[0003] Compared with cast heat sinks commonly used in light-emitting modules, heat sinks made of profiles do not have a draft angle, so the heat sink can have longer and smaller fins, thereby effectively improving the heat dissipation performance. However, due to processing reasons, the profile heat sink cannot produce an annular groove structure, making it difficult to ensure the sealing effect between the heat sink and the lens.

[0004] A module sealing structure is proposed in a light-emitting module based on an enveloping lens cover with application number "2023210129418", in which a plug-in structure is provided on the lens, and the lens and the radiator are assembled and fixed by interference fit in the slot on the profile radiator. The peripheral side of the lens is provided with a downward flange. When the lens cover is on the radiator, the flange wraps around the peripheral side of the radiator and cooperates with the side wall of the radiator to form a sealing groove structure, and a sealant is injected into the sealing groove to form a seal. However, the structure of the above module is closely connected to the plug-in structure on the lens and the heat dissipation is realized, and the connection strength is still relatively low. Summary of the invention

[0005] The object of the present invention is to provide a light emitting module based on side interference reinforcement.

[0006] The present invention provides a light-emitting module based on side interference reinforcement, comprising a lens cover, a heat sink, and a light-emitting board located between the lens cover and the heat sink. The bottom surface of the lens cover is provided with an edge fastening structure. The edge fastening structure comprises one or more groups of snap-fitting convex strips. Each group of snap-fitting convex strips comprises two snap-fitting convex strips respectively arranged on a group of opposite sides of the bottom surface of the lens cover. The heat sink is located between the two snap-fitting convex strips and forms an interference fit.

[0007] Preferably, a guide structure for guiding the heat sink to be inserted between the two clamping convex strips is provided on one side of the bottom of the clamping convex strip close to the middle position of the lens cover.

[0008] Preferably, the guide structure is a bevel chamfered structure.

[0009] Preferably, the snap-fitting convex strip is provided with a plurality of fractures which are sequentially spaced along its length direction.

[0010] Preferably, the bottom edge of the lens cover is provided with a flange structure that is folded downward and surrounds the lens cover. A first sealing groove that surrounds the lens cover is formed between the inner side of the flange structure, the snap-fitting convex strip, and the side wall of the heat sink. The first sealing groove is filled with sealant.

[0011] Preferably, the inner side surface of the flange structure is provided with one or more glue containing spaces recessed inwardly away from the middle position of the lens cover.

[0012] Preferably, the bottom surface of the lens cover is further provided with one or more plug-in structures; the heat sink is provided with slots corresponding to the plug-in structures. The plug-in structures are inserted into the corresponding slots to form an interference fit.

[0013] Preferably, a notch structure aligned with the plug-in structure is provided on the snap-fitting convex strip extending along the length direction of the vertical slot. The first sealing groove is connected to the slot through the notch structure. The sealant in the first sealing groove enters the slot through the notch structure.

[0014] Preferably, the edge fastening structure only includes a set of snap-fitting convex strips arranged on the length edge of the bottom surface of the lens cover; the two snap-fitting convex strips are located on the inner side of the flange structure; and each plug-in structure is located between the two snap-fitting convex strips.

[0015] Preferably, the plurality of plug-in structures are sequentially arranged at intervals, and each plug-in structure comprises one or a plurality of fasteners sequentially arranged at intervals along the extending direction of the corresponding slot.

[0016] Preferably, a groove is provided on one or two sides of the plug-in structure; and a protrusion matching the groove is provided on the side wall of the slot; Preferably, the plug-in structure has a groove on only one side surface; the plug-in structure has a first chamfered structure at the bottom of the side surface without the groove; the slot has a second chamfered structure at the bottom of the side wall without the protrusion. The shapes of the first chamfered structure and the second chamfered structure match each other; Preferably, the bottom surface of the lens cover is provided with a second sealing groove which surrounds the lens cover, the clamping convex strip is located outside the second sealing groove, and the second sealing groove is filled with sealant.

[0017] The present invention has the following beneficial effects: The present invention arranges snap-fitting convex strips in pairs on the lens cover, and snaps the tops of the two opposite side surfaces of the heat sink between the two snap-fitting convex strips, and realizes interference fit through the elastic bending deformation of the two snap-fitting convex strips, thereby improving the stability of the connection between the lens cover and the heat sink at the edge, strengthening the overall connection strength between the lens cover and the heat sink, and effectively reducing the possibility of the lens cover falling off the heat sink.

[0018] The present invention provides a guide structure at the bottom of the clamping convex strip; the guide structure improves the guiding effect when the radiator is inserted between the two clamping convex strips, so that the radiator can be smoothly inserted between the two clamping convex strips.

[0019] The present invention provides multiple fractures at intervals on the snap-fitting convex strips, which facilitates the deformation of the snap-fitting convex strips so that the heat sink can be smoothly inserted between the two snap-fitting convex strips and achieves an interference fit. At the same time, the present invention provides a flange structure on the peripheral side of the lens cover, and a first sealing groove is formed between the flange structure and the side wall of the heat sink. The first sealant is injected into the first sealing groove to achieve sealing. Since the fastener is provided with multiple fractures at intervals, the first sealant flows through the fractures and contacts the heat sink, thereby enhancing the bonding effect of the first sealant on the lens cover and the heat sink, and while achieving the sealing function, it also plays a role in strengthening the connection.

[0020] The present invention provides a notch structure aligned with the plug-in structure on the snap-fit ​​convex strip, so that the first sealing groove and the slot separated by the snap-fit ​​convex strip are connected through the notch structure, so that the first sealant flows into the slot for sealing and bonds the plug-in structure and the slot.

[0021] The present invention arranges an outward convex structure on the flange structure, and the outward convex structure forms an additional glue-containing space on the inner side of the flange structure; when injecting sealant into the first sealing groove, the sealant can be injected from the glue-containing space, and the excess sealant can be accumulated in the glue-containing space.

[0022] The present invention provides an annular second sealing groove on the bottom surface of the lens cover, and a second sealant can be injected into the second sealing groove. The second sealing groove cooperates with the first sealing groove to form a double-layer seal, and the sealing effect is better, and the second sealant also has a bonding effect on the lens and the heat sink. At the same time, the fluidity of the second sealant is lower than that of the first sealant. The sealant with low fluidity has strong bonding force. The lens and the heat sink are bonded by the second sealant to strengthen the connection between the two.

[0023] The present invention has a groove on the side of the plug-in structure, and a protrusion matching the groove on the side wall of the slot; the connection between the lens cover and the heat sink is more stable through the nesting cooperation of the protrusion and the groove.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] In the following embodiments, the direction from the lens cover 1 to the heat sink 2 is taken as the direction from top to bottom. The top, top, and bottom surface of the structure all represent the topmost position of the structure; the bottom, bottom, and bottom surface of the structure represent the bottommost position of the structure; the arrangement direction of the heat sink fins in the heat sink 2 is taken as the front-to-back direction. The lateral extension direction of the heat sink fins in the heat sink 2 is taken as the left-right direction.

[0038] Example 1 like Figure 1 As shown, a light-emitting module based on side interference reinforcement includes a lens cover 1, a light-emitting board and a heat sink 2. The light-emitting board is clamped and fixed between the lens cover 1 and the mounting surface of the heat sink 2. Lamp beads for emitting light are installed on the light-emitting board.

[0039] In this embodiment, the arrangement direction of the heat dissipating fins in the radiator 2 is the arrangement direction between the two width sides of the radiator 2; the lateral extension direction of the heat dissipating fins in the radiator 2 is the arrangement direction between the two length sides of the radiator 2.

[0040] The bottom surface of the lens cover 1 is provided with an edge fastening structure 3 and a plurality of plug-in structures 4; the edge fastening structure 3 is used to clamp the side of the mounting surface of the radiator 2 to improve the connection fastening between the lens cover 1 and the edge of the radiator 2. The plurality of plug-in structures 4 are arranged in sequence and spaced apart in the front-to-back direction. The mounting surface of the radiator 2 is provided with a plurality of slots 21 corresponding to the plug-in structures 4 one by one. The slots 21 extend along the left and right width directions of the radiator 2 and penetrate the left and right edges of the radiator 2 to form a slot structure open at both ends. The plug-in structure 4 is inserted into the corresponding slot 21 to form an interference fit; a through-slot structure matching the plug-in structure 4 is provided on the light-emitting board to prevent the plug-in structure 4 from being blocked by the light-emitting board.

[0041] In this embodiment, the edge fastening structure 3 is only provided on the two length edges of the bottom surface of the lens cover 1, and forms an interference fit with the top of the left and right side surfaces of the heat sink 2, so as to strengthen the structural strength on the left and right sides (i.e., the two length edges) of the light-emitting module. The structural strength on the front and rear sides (i.e., the two width edges) of the light-emitting module is ensured by the plug-in structure 4 located at the front and rear ends of the bottom surface of the lens cover 1.

[0042] The bottom edge of the lens cover 1 is provided with a flange structure 11 that is folded downward and surrounds the periphery. The edge fastening structure 3 includes two snap-fitting convex strips 31. The two snap-fitting convex strips 31 are located on the inner side of the flange structure 11 and are respectively close to the two length sides of the flange structure 11. Each plug-in structure 4 is located between the two snap-fitting convex strips 31.

[0043] The initial spacing between the two snap-fitting ridges 31 (i.e., the spacing when the lens cover 1 and the heat sink 2 are not assembled together) is smaller than the width of the mounting surface of the heat sink 2. The opposite sides of the two snap-fitting ridges 31 are in contact with the left and right sides of the heat sink 2, respectively, and are elastically bent and deformed outwards under the push of the left and right sides of the heat sink 2 to form an interference fit. The interference fit between the two snap-fitting ridges 31 and the left and right sides of the heat sink can strengthen the connection strength between the lens cover 1 and the heat sink 2 on the basis of the interference plug-in structure 4, making the connection more stable and making it difficult for the lens cover 1 to fall off from the heat sink 2.

[0044] In order to facilitate the smooth insertion of the heat sink 2 between the two snap-fitting ridges 31, a concave guide structure 34 is provided on one side of the bottom of the snap-fitting ridge 31 near the middle of the lens cover 1. The guide structure 34 is specifically a chamfered structure, which can guide the two snap-fitting ridges 31 to gradually bend and deform elastically outward when the top of the heat sink 2 is inserted between the two snap-fitting ridges 31, thereby ensuring a stable connection between the lens cover 1 and the heat sink 2.

[0045] In some preferred embodiments, the two snap-fitting convex strips 31 are provided with a plurality of breakouts 32 arranged in sequence along the front-to-back direction. The snap-fitting convex strips 31 separated by the breakouts 32 are separated into mutually independent snap-fitting plates. By breaking the snap-fitting convex strips 31, the snap-fitting convex strips 31 can be more easily deformed, thereby ensuring that the radiator 2 can be smoothly inserted between the two snap-fitting convex strips 31 and achieve interference fit.

[0046] When the lens cover 1 is placed on the heat sink 2, a first sealing groove 5 is formed around the inner side of the flange structure 11, the snap-fitting convex strip 31, and the side wall of the heat sink 2. A first sealant is injected into the first sealing groove 5 to achieve sealing. Since a plurality of cutouts 32 are arranged at intervals on the snap-fitting convex strip 31, the first sealant can flow through the cutouts 32 and contact the heat sink 2. The first sealant bonds the lens cover 1 and the heat sink 2, and while achieving the sealing function, it also plays a role in strengthening the connection.

[0047] The snap-fitting convex strip 31 is also provided with a notch structure 33 aligned with the multiple plug-in structures 4 located in the middle. When the plug-in structure 4 is inserted into the corresponding slot 21, the first sealing groove 5 separated by the snap-fitting convex strip 31 is connected with the slot 21 through the notch structure 33, so that the first sealant flows into the slot 21 for sealing and bonds the plug-in structure 4 with the slot 21.

[0048] The bottom surface of the lens cover 1 is provided with a surrounding heightening strip. The heightening strip is disconnected at the turning point; the heightening strip is located between the two snap-fitting convex strips 31. The heightening strip surrounds the light-emitting board. The heightening strip is used to raise the middle part of the bottom surface of the lens cover 1 to leave installation space for the light-emitting board. The outer side of the heightening strip is provided with a concave and surrounding second sealing groove 12. The second sealing groove 12 is located between the two snap-fitting convex strips 31.

[0049] The second sealant can be injected into the second seal groove 12. The second seal groove 12 cooperates with the first seal groove 5 to form a double-layer seal, which has a better sealing effect, and the second sealant also has a bonding effect on the lens 1 and the heat sink 2. In this solution, the fluidity of the second sealant is lower than that of the first sealant. The sealant with low fluidity has strong bonding force. The lens 1 and the heat sink 2 are bonded by the second sealant to strengthen the connection between the two.

[0050] The flange structure 11 is provided with one or more convex structures 13 protruding away from the middle of the lens cover 1. The thickness of the convex structure 13 is consistent with the thickness of the rest of the flange structure 11, and an additional glue-containing space is formed on the inner side of the flange structure 11; when injecting sealant into the first sealing groove 5, the sealant can be injected from the glue-containing space formed by the convex structure 13, and the excess sealant can be accumulated in the glue-containing space.

[0051] The plug-in structure 4 includes a plurality of fasteners arranged in sequence and spaced apart along the left-right direction (ie, the width direction of the lens cover); all the fasteners are inserted into the corresponding slots 21 on the heat sink to form an interference fit.

[0052] The two fasteners arranged at both ends of the same plug-in structure 4 overlap with the heightening strips located on the two length sides of the lens cover 1 respectively.

[0053] In all the plug-in structures 4, the fasteners of the plug-in structures 4 arranged at both ends overlap the padding strips located on the two width sides of the lens cover 1. In some embodiments, a groove 41 is provided on one side wall of the fastener; a protrusion 22 is provided on a side wall of the slot 21 corresponding to the groove 41. Of the front and rear side walls of the fastener, the side wall with the groove 41 is called the first clamping side, and the side wall without the groove 41 is called the yielding side; of the two groove walls of the slot 21, the groove wall with the protrusion 22 is called the second clamping side, and the side wall without the groove 41 is called the compensation side.

[0054] In some embodiments, the longitudinal section profile of the protrusion 22 is an arc with a radius of 0.8 mm to 1.2 mm (preferably 1 mm). The protrusion 22 has a convex height of 0.3 mm to 0.4 mm (preferably 0.3 mm); the convex height is the distance between the point of the protrusion 22 farthest from the plane where the slot side wall is located and the plane where the slot side wall is located.

[0055] In some embodiments, the protrusion 22 is in a continuous long strip shape, with two ends extending to two side surfaces of the heat sink 2 respectively.

[0056] The bottom of the yielding side of the fastener is provided with a concave first chamfered structure 42; the bottom of the compensating side of the slot 21 is provided with a second chamfered structure 23. The shapes of the first chamfered structure 42 and the second chamfered structure 23 match each other; during the process of inserting the fastener into the groove 41, the bottom of the first clamping side of the fastener contacts the protrusion 22 on the second clamping side of the slot 21 and causes the fastener to bend and deform; the concave first chamfered structure 42 on the yielding side of the fastener forms an avoidance, so that the fastener can be smoothly bent and deformed and inserted into the slot 21. After the fastener is fully inserted into the corresponding slot, the first chamfered structure 42 and the second chamfered structure 23 fit together to avoid forming a sealing structure with too large a gap.

[0057] In some further embodiments, the first chamfered structure 42 and the second chamfered structure 23 are both inclined plane structures; in some other embodiments, the first chamfered structure 42 and the second chamfered structure 23 may also be curved surface structures.

[0058] In some embodiments, the heat sink 2 is made of profiles obtained by extrusion molding of aluminum alloy.

[0059] In some embodiments, the light-emitting board includes a PCB board and a plurality of lamp beads distributed on the PCB board. A plurality of lens units are integrally formed on the lens cover 1. The position of each lens unit corresponds to the position of each lamp bead on the light-emitting board, and is used to distribute the light emitted by the lamp bead. The mounting surface of the heat sink 2 is in contact with the light-emitting board; the power supply line of the light-emitting board is led out through the wire hole in the middle of the heat sink 2.

[0060] In some embodiments, in order to facilitate the insertion of the fastener into the slot 21 , a circular arc chamfer is provided at the edge of the top notch of the slot 21 .

[0061] Example 2 A light-emitting module based on side interference reinforcement, the difference between this embodiment and embodiment 1 is that: the structure of the edge fastening structure 3 is different; In this embodiment, the edge fastening structure 3 includes four snap-fitting convex strips 31. The four snap-fitting convex strips 31 are respectively located on the inner sides of the two length edges and the two width edges of the flange structure 11; after the heat sink is inserted, the four snap-fitting convex strips 31 respectively press against the top of the four side surfaces of the heat sink and bend and deform, thereby comprehensively improving the fastening of the lens cover and the heat sink around.

[0062] Example 3 A light-emitting module based on side interference reinforcement, the difference between this embodiment and embodiment 1 is that there is no plug-in structure 4 and slot 21. In this embodiment, screws are used instead of fasteners and slot 21 to fasten the middle part of the lens cover to the heat sink.

[0063] Example 4 A light-emitting module based on side interference reinforcement, the difference between this embodiment and embodiment 1 is that the structures of the fasteners of the plug-in structure 4 and the slot 21 are different.

[0064] like Fig. 9 and Fig.10 As shown, in this embodiment, the fastener of the plug structure 4 is not provided with the first chamfer structure 42; the slot wall of the slot 21 is not provided with the second chamfer structure 23. Both sides of the fastener are provided with grooves 41; both slot walls of the slot 21 are provided with protrusions 22.

[0065] In some embodiments, the bottom of the fastener is provided with a slot 43 that provides space for the fastener to shrink and deform inward; the slot 43 extends from the bottom of the fastener (specifically, the end away from the lens cover 1) to the top. In some further embodiments, in the same plug-in structure 4, on the two fasteners arranged at the left and right ends of the lens cover 1, a closing structure is provided at the opening of the slot 43 on one side away from the middle position of the lens cover 1, so that the two fasteners arranged at the left and right ends play the role of a closed slot.

[0066] In this embodiment, the depth of the fasteners of the slot 21 and the plug-in structure 4 is Example 5 A light-emitting module based on side interference reinforcement, the difference between this embodiment and embodiment 4 is that the structures of the plug-in structure 4 and the slot 21 are different.

[0067] like Fig.11 As shown, in this embodiment, the fastener of the plug-in structure 4 is not provided with a groove 41, and the slot wall of the slot 21 is not provided with a protrusion 22. The bottom of the fastener is provided with an intermediate groove 43 to provide space for the fastener to shrink and deform inward.
