[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example
[0028] See Figures 1 to 5 As shown, a novel spotlight heat sink module includes a heat sink body 1. The heat sink body has a cavity 2 for mounting a light source module 13. A pressure cover 3 for limiting the position of the light source module is provided in the cavity. In this embodiment, the heat sink body is a conventional material structure component of the prior art, specifically an aluminum structure component. The depth of the cavity can be processed and set as needed. The pressure cover can be a plastic structure component or an aluminum structure component.
[0029] Furthermore, in this embodiment, the lower part of the inner wall of the accommodating cavity is integrally formed with a plurality of snap-fit protrusions 4, and the middle part of the snap-fit protrusions is radially provided with a relief groove 5; the setting of snap-fit protrusions and the relief groove in the middle part can improve the strength of the overall structure, and the outer wall of the pressure cover is provided with an L-shaped snap-fit groove 6; the lower part refers to the part near the opening of the accommodating cavity.
[0030] During assembly, the pressure cap is inserted into the accommodating cavity, and the snap-fit protrusion engages with the L-shaped snap-fit groove from the vertical groove and rotates, causing the snap-fit strip below the clearance groove to engage with the transverse groove of the L-shaped snap-fit groove. Simultaneously, the side of the transverse groove in the L-shaped snap-fit groove engages with the clearance groove. This dual connection and limiting mechanism, achieved through the clearance groove and the transverse groove of the L-shaped snap-fit groove, improves the stability and reliability of the connection and prevents the pressure cap from loosening, shaking, or shifting.
[0031] In this embodiment, since the cover and the heat sink body are connected by a screw fastener, the cover can be quickly disassembled as needed to replace the internal lens structure 14, such as replacing the lens structure with a different beam angle to meet the lighting needs of different situations, thus improving the ease of lens structure replacement.
[0032] Furthermore, in this embodiment, a spring piece 7 is provided in the transverse groove of the L-shaped snap-fit groove, and an abutment protrusion 8 is fixed to the end of the spring piece. During assembly, the lower part of the snap-fit protrusion is located in the transverse groove of the L-shaped snap-fit groove and is abutted and limited by the abutment protrusion. The distance between the abutment protrusion and the end wall of the transverse groove of the L-shaped snap-fit groove is greater than or equal to the width of the snap-fit protrusion. Through the above structure, the snap-fit protrusion can be prevented from loosening or falling off, improving the stability and reliability of installation. Moreover, the abutment protrusion is a hemispherical structure, which allows the snap-fit protrusion to be separated from the L-shaped snap-fit groove when the external force is greater than the frictional force between the abutment protrusion and the snap-fit protrusion, facilitating maintenance operations.
[0033] In this embodiment, a spare support through-hole column 9 is provided on the upper part of the inner wall of the accommodating cavity; a spare through-hole 10 is provided on the pressure cap. In practical applications, spare screws or the like can also be used for connection and positioning to meet the installation requirements of different situations.
[0034] In this embodiment, the number of the buckle protrusions is two or three.
[0035] In practical applications, heat dissipation fins 11 are integrally formed on the outer wall of the heat sink body. Furthermore, in this embodiment, some of the heat dissipation fins are shaped similarly to the product logo. This ensures overall heat dissipation while also enhancing the decorative effect.
[0036] In this embodiment, the outer wall of the pressure cap is provided with a screw-on protrusion 12 for installing the face ring. This facilitates quick connection with components such as the face ring. By rotating the protrusion, the face ring can be quickly installed and removed. Furthermore, different light source color temperatures, lamp body shapes, and various face ring colors can be changed as needed. The face ring can be installed and removed directly without disassembling the heat sink body and pressure cap, improving the ease of installation and removal and significantly reducing the cost of manual installation and removal.
[0037] This utility model has positive effects: The structure of this utility model is reasonably designed. It has a snap-fit protrusion on the inner wall of the cavity, and a relief groove in the radial direction of the middle of the snap-fit protrusion. At the same time, it cooperates with the L-shaped snap-fit groove on the outer wall of the cover. During assembly, the snap-fit protrusion below the relief groove is engaged in the transverse groove of the L-shaped snap-fit groove, and the side of the transverse groove of the L-shaped snap-fit groove is engaged in the relief groove. This can improve the convenience and effectiveness of assembly. The relief groove can also prevent the cover from shaking or shifting, improve the stability and reliability of the connection, and make disassembly and assembly convenient and easy to assemble and maintain.
[0038] Furthermore, a spring piece is provided in the transverse groove of the L-shaped buckle groove, and the end of the spring piece is fixed with a buckling protrusion. When the buckle protrusion is inserted into the transverse groove of the L-shaped buckle groove, the buckling protrusion achieves a limit to prevent loosening or falling off, thereby improving the stability and reliability of use.
[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
