[0050] In the related art, the functional module 20 of the lamp body module 100 is usually installed on the lamp body 10 by bolt fixing. At present, when the lamp body module 100 needs to be maintained or replaced, maintenance personnel are usually required to carry corresponding disassembly tools to perform high-altitude operations to remove the functional module 20 from the lamp body 10 of the lamp body module 100. Not only is the operation more complicated and the work efficiency is low, but there is also a safety risk of the disassembled workpiece falling from a high altitude. The utility model proposes a lamp body module 100.

[0051] See also Figures 1 to 6 In one embodiment of the present invention, the lamp body module 100 includes:

[0052] A lamp body 10, wherein the lamp body 10 has a mounting position 11;

[0054] A lock release member 30, one end of which is disposed on the lamp body 10, and the other end of which is located on the peripheral side of the functional module 20, the lock release member 30 has a movably disposed lock release structure 321, and the lock release structure 321 has a locked position and an unlocked position in its movable travel;

[0055] When the lock-release structure 321 is in the locked position, the lock-release structure 321 abuts against the outer peripheral wall of the functional module 20 and cooperates with the functional module 20 to lock the functional module 20 in the installation position 11;

[0056] When the lock-release structure 321 is at the unlocking position, the lock-release structure 321 is separated from the outer peripheral wall of the functional module 20 , so that the functional module 20 is unlocked at the installation position 11 .

[0057] The technical solution of the utility model is that a lock release member 30 is arranged on the peripheral side of the installation position 11 of the lamp body 10, and the lock release member 30 has a lock release structure 321 that can be movably arranged, so as to have a locking position and an unlocking position on the movable stroke. When the functional module 20 needs to be fixed at the installation position 11, it is only necessary to move the lock release structure 321 to the locking position, so that the lock release structure 321 and the outer peripheral wall of the functional module 20 can be limitedly matched, thereby the functional module 20 can be locked at the installation position 11 by the lock release member 30. When the functional module 20 needs to be unlocked at the installation position 11, it is only necessary to move the lock release structure 321 to the unlocking position, so that the lock release structure 321 and the outer peripheral wall of the functional module 20 can be separated from each other, thereby the functional module 20 can be directly removed from the installation position 11. In this way, the lock release member 30 can realize the quick disassembly and assembly of the functional module 20, improve the convenience of disassembly and assembly of the lamp body module 100, and help improve the maintenance efficiency of the lamp body 10 module.

[0058] See also Figure 2 In an embodiment of the present utility model, the lock release member 30 comprises:

[0059] A mounting portion 31 detachably connected to the lamp body 10 ; and

[0060] A lock release portion 32, the lock release portion 32 is bent and connected to one end of the mounting portion 31 and arranged side by side with the functional module 20, and the lock release structure 321 is movably provided at one end of the lock release portion 32 away from the mounting portion 31;

[0061] The lock-release structure 321 is provided with one of the plug hole 321c and the plug block 221, and the outer peripheral wall of the functional module 20 is provided with the other of the plug hole 321c and the plug block 221, and the plug hole 321c and the plug block 221 are arranged opposite to each other;

[0062] The lock-release structure 321 is used to move away from the functional module 20 under external force so that the plug block 221 is separated from the plug hole 321c, or to move toward the functional module 20 so that the plug block 221 is limited in the plug hole 321c.

[0063] In some embodiments, the bottom wall of the functional module 20 is arranged at the installation position 11, the plug block 221 is arranged at the outer peripheral wall of the functional module 20 and extends in a direction perpendicular to the outer peripheral wall of the functional module 20, and the locking and releasing structure 321 is provided with a plug hole 321c on the side facing the functional module 20, which is used to be arranged opposite to the plug block 221. In this way, when the locking and releasing structure 321 moves to the locking position and the plug block 221 and the plug hole 321c are plugged and matched, the hole wall of the plug hole 321c located in the locking and releasing structure 321 can limit the plug block 221 on the functional module 20, so as to limit the functional module 20 from leaving the installation position 11 in the direction away from the lamp body 10 through the locking and releasing structure 321 fixed to the lamp body 10. Of course, the technical solution of the utility model is not limited to this. In some embodiments, the plug hole 321c can also be provided on the outer peripheral wall of the functional module 20, and the plug block 221 can be protruded on the side of the locking and releasing structure 321 facing the functional module 20, which will not be described in detail here.

[0064] See also Figure 2 and Figure 3 In an embodiment of the present utility model, a mounting structure 12 is provided on a side of the lamp body 10 facing the functional module 20 . The mounting structure 12 is provided on a peripheral side of the mounting position 11 and is threadedly connected to the mounting portion 31 .

[0065] The mounting structure 12 may be provided in the form of a base, and a first connection hole is provided on the mounting surface of the base; the outer surface of the mounting portion 31 may be fitted with the mounting surface of the base, and a second connection hole is provided on the outer surface of the mounting portion 31. In this way, the second connection hole and the first connection hole may be sequentially penetrated by a fastener and connected to the base, so as to realize the fixed installation of the lock release member 30 on the lamp body 10.

[0066] See also Figure 5 and Figure 6 In an embodiment of the present utility model, the lock-release structure 321 includes:

[0067] a first elastic section 321a, one end of which is fixedly disposed on a side of the lamp body 10 facing the functional module 20, and the other end of which is inclined in a direction away from the lamp body 10 and close to the functional module 20; and

[0068] The second elastic segment 321 b has one end connected to one end of the first elastic segment 321 a away from the lamp body 10 , and the other end thereof is tilted in a direction away from the lamp body 10 and away from the functional module 20 .

[0069] The end of the first elastic section 321a away from the lamp body 10 is arranged in an inclined direction away from the lamp body 10 and close to the functional module 20, and the first elastic section 321a is provided with the plug block 221 or the plug hole 321c in the above-mentioned embodiment on the side facing the functional module 20. In this way, the plug block 221 or the plug hole 321c on the first elastic section 321a can be arranged close to the outer peripheral wall of the functional module 20, so as to facilitate the limited cooperation between the first elastic section 321a and the functional module 20, thereby realizing the locking operation between the lock release member 30 and the functional module 20.

[0070] Furthermore, one end of the second elastic segment 321b is connected to the end of the first elastic segment 321a, and the other end is tilted away from the lamp body 10 and away from the functional module 20. In this way, when the lock-release structure 321 moves to the locked position, at least a portion of the second elastic segment 321b can be separated from the outer peripheral wall of the functional module 20 and form a gap with the outer peripheral wall of the functional module 20. In this way, it is convenient for the user to move the second elastic segment 321b through the gap between the second elastic segment 321b and the outer peripheral wall of the functional module 20, so as to drive the second elastic segment 321b to drive the first elastic segment 321a to move away from the functional module 20, so that the lock-release structure 321 moves to the unlocking position, thereby realizing the unlocking operation of the lock-release structure 321.

[0071] See also Figure 2 In the embodiment of the utility model, the insert block 221 is provided with a plurality of insert blocks 221, and the plurality of insert blocks 221 are arranged in sequence at intervals;

[0072] There are a plurality of inserting blocks 221 , and each inserting block 221 is disposed corresponding to one of the inserting holes 321 c .

[0073] In this way, by plugging and matching multiple groups of plug blocks 221 and plug holes 321c, it is beneficial to improve the connection stability between the lock release structure 321 and the functional module 20, so that the functional module 20 can be stably locked at the installation position 11 of the lamp body 10. Among them, the multiple plug blocks 221 can be arranged in sequence in a direction away from the lamp body 10, or can be arranged in an array, or in other arrangements. The specific implementation method can be set according to actual needs and is not limited here.

[0074] See also Figures 1 to 6 In the embodiment of the utility model, a mounting block 222 is protruded from one side of the functional module 20 facing the lock release member 30, and the mounting block 222 defines a limiting groove 222a;

[0075] The lock release portion 32 further includes a limiting structure 322 . The limiting structure 322 and the lock release structure 321 are arranged side by side and are disposed opposite to the limiting groove 222 a . The limiting structure 322 is used for plugging and matching with the limiting groove 222 a .

[0076] In this way, the connection stability between the locking part 32 of the locking member 30 and the functional module 20 can be improved by plugging and matching between the limiting structure 322 and the limiting groove 222a on the mounting block 222, so that the locking structure 321 and the functional module 20 can be accurately docked and matched. In addition, by providing the limiting groove 222a and the limiting structure 322, the inner wall of the limiting groove 222a can also be used to limit the limiting structure 322, thereby reducing the risk of the functional module 20 being offset relative to the mounting position 11 of the lamp body 10.

[0077] In addition, since the extension direction of the limiting groove 222a is the same as the arrangement direction of the lamp body 10 and the functional module 20, during the disassembly and assembly of the functional module 20, the limiting groove 222a can also move relative to the limiting structure 322 to guide the limiting structure 322.

[0078] See also Figure 5 In the embodiment of the present utility model, the end of the limiting structure 322 away from the lamp body 10 has a guide surface 322a, and the guide surface 322a is inclined.

[0079] In this way, when the limiting structure 322 is inserted into the limiting groove 222a, the guide surface 322a can play a guiding role, so as to facilitate accurate alignment between the limiting structure 322 and the limiting groove 222a.

[0080] See also Figures 1 to 6 In the embodiment of the present utility model, at least two of the limiting structures 322 are provided, and at least two of the limiting structures 322 are provided on both sides of the locking and releasing structure 321;

[0081] At least two mounting blocks 222 are provided, and each mounting block 222 is provided with a limiting groove 222 a corresponding to a limiting structure 322 .

[0082] This helps to further improve the connection stability between the locking portion 32 of the locking member 30 and the functional module 20 .

The heat dissipation assembly 22 may be limitedly matched with the locking release 30 to be fixedly covered above the notch of the slot structure, so that the slot assembly may be limited in the slot structure by the heat dissipation assembly 22.

[0087] In some embodiments, the light source assembly 21 and the heat dissipation assembly 22 may also be detachably connected or integrally arranged, so that when the locking structure 321 and any one of the light source assemblies 21 and the locking structure 321 of the locking member 30 are limitedly engaged, the light source assembly 21 and the heat dissipation assembly 22 can be simultaneously limited at the installation position 11 of the lamp body 10.
