[0034] Next, the technical solutions of the present application will be further described in conjunction with the embodiments and the drawings.

[0035] Please refer to Figures 1 to 4 In a first aspect, an embodiment of the present application provides an installation mechanism 1, including a base 10, a fixing bracket 20, and a functional component 30. The base 10 is provided with a receiving cavity 11 having an opening. The fixing bracket 20 is installed in the receiving cavity 11. The fixing bracket 20 includes a first buckle portion 21 and a first connecting portion 22. The functional component 30 includes a main body portion 31, a mounting portion 32, and a threaded fastener 33. The mounting portion 32 is connected to the main body portion 31. The mounting portion 32 includes a second buckle portion 321 and a second connecting portion 322. The first buckle portion 21 is used for snap connection with the second buckle portion 321. The first connecting portion 22 or the threaded fastener 33 passes through the second connecting portion 322, and the second connecting portion 322 is located between the first connecting portion 22 and the threaded fastener 33 in the opening direction of the receiving cavity 11 (see Figures 1 to 4 the x direction in

[0036] ). The first connecting portion 22 is used for threaded connection with the threaded fastener 33, and the axial direction of the threaded fastener 33 is parallel to the opening direction of the receiving cavity 11.

[0037] In this way, by providing the detachable connection between the mounting portion 32 of the functional component 30 and the fixing bracket 20, the functional component 30 can be removed or installed from the receiving cavity 11 of the base 10. The mounting portion 32 and the fixing bracket 20 adopt a connection method combining snap connection and threaded connection. The first buckle portion 21 and the second buckle portion 321 are snap-connected to assist in limiting the mounting portion 32, so as to facilitate the positioning of the first connecting portion 22 and the second connecting portion 322, which is beneficial to the threaded connection between the functional component 30 and the fixing bracket 20. The first connecting portion 22 is used for threaded connection with the threaded fastener 33, and the axial direction of the threaded fastener 33 is parallel to the opening direction of the receiving cavity 11, so that the threaded fastener 33 locks and connects the functional component 30 and the fixing bracket 20 along the direction parallel to the opening direction of the receiving cavity 11, that is, the functional component 30 is installed along the direction parallel to the opening direction of the receiving cavity 11, so that the operator does not need to occupy the space inside the receiving cavity 11 during installation. Thus, it can not only reduce the structural interference of the components or structural parts inside the receiving cavity 11 to the functional component 30 when installing the functional component, facilitating the assembly of the functional component 30 and the fixing bracket 20, but also enable the receiving cavity 11 not to reserve the moving space for the mounting portion 32 during threaded connection, which is beneficial to reducing the volume of the lamp, and further improving the convenience of disassembly and assembly while meeting the miniaturization design. Optionally, the functional component 30 can be a power module, a ballast, or other structures with a high replacement frequency, which can be specifically set according to actual needs and is not limited here.

[0038] It should be noted that the threaded fastener 33 can be a screw, a stud or a nut. When the threaded fastener 33 is a screw or a stud, the axial direction of the screw (or bolt) is the axial direction of the threaded fastener 33, and the axial direction of the screw (or bolt) is parallel to the opening direction of the accommodating cavity 11. When the threaded fastener 33 is a nut, the axial direction of the above-mentioned threaded fastener 33 refers to the center line direction of the threaded hole of the nut. At this time, the center line direction of the threaded hole of the nut is parallel to the opening direction of the accommodating cavity 11.

[0039] In some embodiments, the fixing bracket 20 includes a first supporting portion 23 extending along the opening direction of the accommodating cavity 11. The first clamping portion 21 is located at one end of the first supporting portion 23, and the first connecting portion 22 is connected to the other end of the first supporting portion 23. The functional component 30 further includes a second supporting portion 323. The second clamping portion 321 is located at one end of the second supporting portion 323, and the second connecting portion 322 is connected to the other end of the second supporting portion 323.

[0040] In this way, the first clamping portion 21 and the first connecting portion 22 are respectively located at both ends of the first supporting portion 23, and the second clamping portion 321 and the second connecting portion 322 are respectively located at both ends of the second supporting portion 323, so that one end of the functional component 30 and the fixing bracket 20 are connected by clamping, and the other end is connected by threading. This is beneficial to improving the connection stability between the functional component 30 and the fixing bracket 20. At the same time, it can also make the fitting area between the functional component 30 and the fixing bracket 20 larger, which is beneficial to the conduction of the heat generated by the functional component 30 and improves the heat dissipation efficiency of the functional component 30.

[0041] Optionally, the first connecting portion 22 and the first clamping portion 21 are respectively arranged on both sides of the first supporting portion 23 and extend away from each other. Thus, the fixing bracket 20 forms a Z-shaped structure, which is beneficial to increasing the contact area between the functional component 30 and the fixing bracket 20, thereby improving the reliability of the structure. At the same time, the first clamping portion 21 and the first connecting portion 22 are respectively located on both sides of the first supporting portion 23, which can facilitate the movement of the functional component 30 in the opening direction of the accommodating cavity 11 when it is disconnected, and avoid the interference of the first connecting portion 22 and the second connecting portion 322 on the functional component 30 during the process of switching from disconnection to clamping connection between the first clamping portion 21 and the second clamping portion 321, so as to facilitate the assembly and disassembly of the functional component 30 and the fixing bracket 20.

[0042] In some embodiments, the first connecting portion 22 is located on a side of the fixing bracket 20 close to the opening. Thus, the position where the first connecting portion 22 is connected to the second connecting portion 322 is located on a side close to the opening of the accommodating cavity 11, which is conducive to enabling an operator to operate outside the accommodating cavity 11 or at a position close to the outside of the accommodating cavity 11 when connecting the first connecting portion 22 and the second connecting portion 322, so that the first connecting portion 22 and the second connecting portion 322 have a larger operable space during connection, thereby reducing the installation influence of the components or structural members located inside the accommodating cavity 11 on the functional component 30, facilitating the connection between the first connecting portion 22 and the second connecting portion 322, and further improving the disassembly and assembly convenience of the components inside the lamp.

[0043] Optionally, the first connecting portion 22 is provided with a first threaded hole 220, the second connecting portion 322 is provided with an installation hole 3220 penetrating therethrough, and the threaded fastener 33 is used to sequentially pass through the installation hole 3220 and the first threaded hole 220, and the threaded fastener 33 is threadedly connected to the first threaded hole 220. At this time, the threaded fastener 33 can be any one of a bolt, a stud, a screw, etc., which is convenient for the disassembly and replacement of the threaded fastener 33 and is conducive to improving the reliability of the installation mechanism 1. In this way, when the functional component 30 is installed, it first extends into the accommodating cavity 11 through the opening and is snap-connected by the first snap portion 21 and the second snap portion 321. At this time, the installation hole 3220 and the first threaded hole 220 are correspondingly communicated, and then the threaded fastener 33 passes through the installation hole 3220 and is threadedly connected to the first threaded hole 220, so that the installation portion 32 is locked and installed on the fixing bracket 20 under the threaded cooperation between the threaded fastener 33 and the first threaded hole 220. Since the installation hole 3220 provided on the second connecting portion 322 is smooth, it is conducive to the second connecting portion 322 adapting to different sizes of threaded fasteners 33, enabling the second connecting portion 322 to be used in cooperation with different sizes of the first connecting portion 22, which is conducive to improving the versatility of the functional component 30.

[0044] It can be understood that in some other embodiments, the installation hole 3220 can also be provided with internal threads to form a second threaded hole to improve the connection reliability between the first connecting portion 22 and the second connecting portion 322. Optionally, the center line directions of the first threaded hole 220 and the installation hole 3220 are perpendicular to the buckling direction of the first snap portion 21 and the second snap portion 321, so as to improve the stability of the installation structure while facilitating the installation of the functional component 30, and is conducive to making the functional component 30 fit against the heat dissipation component of the lamp to improve the heat dissipation efficiency.

[0045] It can be understood that in some other embodiments, the center line directions of the first threaded hole 220 and the installation hole 3220 can also be parallel to the buckling direction of the first snap portion 21 and the second snap portion 321.

[0046] Optionally, the threaded fastener 33 may be a bolt, a screw, a screw rod, etc., which can be specifically set according to actual requirements and are not limited here.

[0047] It can be understood that in some other embodiments, the threaded fastener 33 may also be an internally threaded nut. The first connecting portion 22 is provided with a stud, and the second connecting portion 322 is provided with an installation hole 3220 penetrating therethrough. The stud is inserted through the installation hole 3220 to limit the position of the installation portion 32, so as to facilitate the installation of the threaded fastener 33. Finally, the threaded fastener 33 is threadedly connected to the stud, so that the second connecting portion 322 is clamped and locked by the first connecting portion 22 and the threaded fastener 33. Since the smooth installation hole 3220 is provided on the second connecting portion 322, it is beneficial for the stud to pass through the second connecting portion 322, which can not only facilitate the installation of the functional component 30, but also be beneficial to improving the versatility of the functional component 30.

[0048] Please refer to Figure 3 and Figure 4 , in some embodiments, the first snap portion 21 is inserted into the second snap portion 321 along the opening direction of the accommodating cavity 11, so that the first snap portion 21 is snap-connected to the second snap portion 321 to limit the movement of the installation portion 32 in a direction perpendicular to the opening direction of the accommodating cavity 11.

[0049] In this way, the functional component 30 only needs to be inserted along the opening direction of the accommodating cavity 11 and snap-connected to the first snap portion 21, and then locked by the threaded fastener 33, and the installation of the functional component 30 can be completed. The movement path of the functional component 30 is a linear movement, which can make the installation of the functional component 30 simpler and more convenient, so as to improve the installation convenience of the functional component 30.

[0050] Refer to Figure 4 , Figure 6 and Figure 8 , optionally, one of the first snap portion 21 and the second snap portion 321 is a protruding structure protruding relative to the first support portion 23 or the second support portion 323, the protruding structure extends along the opening direction of the accommodating cavity 11, and the other of the first snap portion 21 and the second snap portion 321 is a through notch structure. The protruding structure passes through the notch structure, and the notch structure extends along a direction parallel to the opening direction of the accommodating cavity 11 and a direction perpendicular to the opening direction of the accommodating cavity 11.

[0051] In this way, it is not only convenient for the convex structure to be inserted into the notch structure, but also enables the bottom of the functional component 30 to be closer to the bottom wall of the accommodation cavity 11 after the first buckle portion 21 and the second buckle portion 321 are buckled and connected, which is beneficial to the bottom of the functional component 30 abutting against the bottom wall of the accommodation cavity 11, thereby facilitating heat transfer and improving the heat dissipation efficiency. At the same time, it can also make reasonable use of space, which is beneficial to the miniaturization design of the lamp and improves the structural reliability of the installation mechanism 1.

[0052] Optionally, the notch structure can be a through hole or an edge notch, and the convex structure can be a T-shaped structure (see Figure 3 and Figure 4 ), an L-shaped structure (see Figure 5 and Figure 6 ), or a Z-shaped structure (see Figure 7 and Figure 8 ), etc. Specifically, it can be set according to actual needs and is not limited here.

[0053] Please refer to Figure 1 and Figure 2 again. In some embodiments, the number of the fixing brackets 20 can be two, and the number of the mounting portions 32 is two. The two mounting portions 32 are respectively connected to both sides of the main body portion 31, so as to improve the connection reliability between the functional component 30 and the fixing brackets 20.

[0054] Optionally, the fixing bracket 20 further includes a fixing portion 24. The fixing portion 24, the first connecting portion 22, and the first supporting portion 23 are perpendicular to each other in pairs, and the fixing portion 24 is detachably connected to the base 10. Thus, it can not only cooperate with the structural design of the base 10 to improve the connection reliability between the fixing bracket 20 and the base 10 and the functional component 30, but also improve the structural reliability of the fixing bracket 20 and avoid structural interference between different connection structures.

[0055] Optionally, the fixing portion 24 and the first buckle portion 21 are respectively connected to both sides of the first supporting portion 23 and extend away from each other, so as to ensure that the assembly of the fixing bracket 20 and the functional component 30 is not affected after the fixing portion 24 is connected to the base 10, and it is also convenient for the replacement and maintenance of the fixing bracket 20.

[0056] In some embodiments, the main body portion 31 is disposed in close fit with the inner wall of the accommodation cavity 11. This can facilitate the heat transfer of the functional component 30 to the side wall of the base 10, so as to be dissipated to the external environment through the housing of the base 10, thereby improving the heat dissipation efficiency.

[0057] Optionally, the installation mechanism 1 further includes a heat conducting member, and the heat conducting member is disposed between the base 10 and the main body portion 31. By transferring the heat generated by the functional component 30 during operation to the side wall of the base 10 through the heat conducting member, the heat transfer efficiency can be improved, so as to improve the heat dissipation efficiency of the lamp.

[0058] Optionally, the material of the heat conducting member may be any one of heat conducting silica gel, heat conducting silicone grease, graphite, phase change material, etc., which can be specifically set according to actual requirements and will not be limited here.

[0059] In a second aspect, the present application also provides a lamp (not shown), including the mounting mechanism 1 described in the first aspect above.

[0060] It can be understood that since the lamp includes the mounting mechanism 1 described in the first aspect above, the lamp has the beneficial effects of the mounting mechanism 1 described in the first aspect above, which will not be elaborated here.

[0061] The embodiments of the present application have been described in detail above with reference to the drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present application.
