[0032] The die-cast bottom shell body 1 is made of aluminum alloy die casting, which has better waterproof performance and better resistance to ultraviolet aging. The back of the die-cast bottom shell body 1 is provided with a mounting bracket assembly 5 for mounting internal components such as PCB boards. The die-cast bottom shell body 1 is provided with a handle mounting platform 12, which is connected to the handle base 21, so that the handle 2 can be installed on the die-cast bottom shell body 1, which facilitates the handling and operation of the bottom shell.
[0033] The upper end of the die-cast bottom shell body 1 is provided with a waterproof assembly mounting seat 13 symmetrically left and right, and the waterproof assembly 3 is fitted in the waterproof assembly mounting seat 13, which ensures the waterproof performance of the bottom shell; the waterproof assembly 3 is provided with a waterproof base 31, the bottom of the waterproof base 31 is provided with an N-shaped waterproof ring 32 in the contact surface with the die-cast bottom shell body 1 to prevent penetration, the waterproof base 31 is provided with a middle waterproof ring 33 around the contact surface with the side of the die-cast bottom shell body 1, the upper surface of the waterproof base 31 is provided with an upper waterproof ring 34, and a waterproof cover 35 is covered above the waterproof base 31 and tightly combined with the upper waterproof ring, so that the multiple waterproof structures ensure good waterproof effect; the middle waterproof ring 33 is provided with a ring wall 331, and the ring wall 331 is provided with a first sealing ring 332, a second sealing ring 333 and a third sealing ring 334 to enhance the waterproof capacity. The upper waterproof ring 34 is provided with an inner sealing ring 341, an outer sealing ring 342 and a sealing hole 343, the screw for fixing the waterproof cover 35 passes through the sealing hole 343, and the overall waterproof capacity is further enhanced.
[0034] The die-cast bottom shell body 1 is also provided with a rotary knob lock mounting seat 14, and the rotary knob lock 4 is installed in the rotary knob lock mounting seat 14, and the position of the rotary knob lock 4 relative to the die-cast bottom shell body 1 can be changed by rotating the rotary knob lock 4, so that the locking and unlocking functions are realized. The rotary knob lock mounting seat 14 comprises a pressing sheet 41, a column rotary knob 42 and a screw 43. The pressing sheet 41 is fixed to the rotary knob lock mounting seat 14 by the screw, the pressing sheet 41 is provided with a notch 411, the lower end of the column rotary knob 42 is provided with a lock tongue 422, the column rotary knob 42 passes through the middle part of the pressing sheet 41 and can rotate relatively, and the upper end of the column rotary knob 42 is provided with locking side wings 421 on both sides. The shape and size of the locking side wings 421 are smaller than those of the notch 411, after the column rotary knob 42 is rotated, the locking side wings 421 are fitted with the notch 411, so that the column rotary knob can be disassembled, which is convenient for maintenance and replacement, and the application scenarios are expanded.
[0035] The mounting bracket assembly 5 can correspond to different products by changing the size and model of the mounting bracket assembly 5, so as to save the cost of mold opening.
[0036] When the die-cast bottom shell body 1 and the mounting bracket assembly 5 need to be separated, the fastening and separation of the bottom shell and the LED module can be realized by operating the rotary knob lock 4, and the column rotary knob 42 is rotated. Since the shape and size of the locking side wings 421 are smaller than those of the notch 411 on the pressing sheet 41, the locking side wings 421 gradually fit with the notch 411 during the rotation process. When the two are completely fitted, the column rotary knob 42 can be taken out of the pressing sheet 41, and then the whole rotary knob lock 4 is disassembled from the rotary knob lock mounting seat 14, so that the unlocking operation is realized. When locking is needed, reverse operation can be performed.
[0037] Working principle: the fastening and separation of the bottom shell and the LED module can be realized by operating the knob lock 4, the rotating column rotating knob 42 is rotated, and because the shape and size of the locking side wing 421 is smaller than the size of the notch 411 on the pressing plate 41, the locking side wing 421 gradually fits with the notch 411 during rotation. When the two are completely fitted, the rotating column rotating knob 42 can be taken out of the pressing plate 41, and then the entire rotating knob lock 4 is detached from the rotating knob lock mounting seat 14, realizing the unlocking operation. When locking is required, reverse operation can be performed.
[0038] The LED module generates heat during operation, and the heat is first transmitted to the die-cast bottom shell body 1 in close contact with the lamp group. Because the aluminum alloy die-cast bottom shell body 1 has good heat conduction performance, the heat can be rapidly conducted inside the bottom shell, and heat exchange with the outside air through the bottom shell surface is performed, so that the heat is dissipated to the surrounding environment, thereby realizing the heat dissipation function of the LED module and ensuring that the LED module works in an appropriate temperature range.
