[0036] Embodiment 2
[0037] Refer to Figures 3-8For the second embodiment of the utility model, the embodiment is based on the previous embodiment.
[0038] Specifically, the rotating shaft 2014 is provided with a spiral groove 2014-1, the moving block 2013 is sleeved outside the rotating shaft 2014, the clamping block 2015 is fixed on the moving block 2013, the clamping block 2015 slides in the spiral groove 2014-1, when the rotating shaft 2014 rotates, the clamping block 2015 will slide in the spiral groove 2014-1, and then drive the moving block 2013 to move along the direction of the rotating shaft 2014, so that the baffle 2012 is driven to move.
[0039] Specifically, the trigger piece 202 includes a rotating disc 2021 fixed on the rotating shaft 2014, the rotating disc 2021 is fixed with a rotating plate 2022, the rotating plate 2022 rotates to drive the rotating disc 2021 to rotate, so that the rotating shaft 2014 rotates.
[0040] The shell 101 is provided with a first moving groove 101-2, the first moving groove 101-2 is provided with an expansion block 2023, one end of the expansion block 2023 is fixed to the inner wall of the first moving groove 101-2, the other end is fixed with a moving plate 2024, the thickness of the shell 101 close to the fixed block 2011 is thicker, so as to set the expansion block 2023, and the inner wall of the first moving groove 101-2 is close to the inner surface of the shell 101, so as to ensure that the temperature inside the shell 101 can be conducted to the shell 101 in time.
[0041] The expansion block 2023 has the characteristics of thermal expansion and cold contraction, when the temperature in the shell 101 rises, when the expansion trigger temperature of the expansion block 2023 is reached, the expansion block 2023 will expand, and push the moving plate 2024 to move along the first moving groove 101-2, so as to open the ventilation groove 101-1 and form an additional heat dissipation channel.
[0042] When it rains, raindrops fall on the surface of the spotlight, which helps the spotlight to dissipate heat, and the temperature in the shell 101 will not reach the expansion trigger temperature of the expansion block 2023, so the ventilation groove 101-1 will not be opened, and the rainwater will not enter the inside of the shell 101 through the ventilation groove 101-1.
[0043] The pitch of the spiral groove 2014-1 is large, so that the expansion block 2023 expands to push the moving plate 2024 to move a small distance, under the cooperation of the spiral groove 2014-1 and the clamping block 2015, the moving block 2013 can move a large distance, so as to realize the opening and closing of the ventilation groove 101-1.
[0044] In the initial case, the card block 2015 is located in the spiral groove 2014-1 and is attached to the inner wall near the side of the rotating disc 2021. At this time, the rotating plate 2022 does not contact the moving plate 2024. Only when the expansion block 2023 expands to a certain extent, the moving plate 2024 will contact the rotating plate 2022, and then press the rotating plate 2022, so that the rotating plate 2022 rotates.
[0045] Specifically, the heat dissipation assembly 200 further comprises a locking piece 203, which is used to lock the position of the baffle 2012, so as to ensure that the baffle 2012 will not be accidentally moved due to external force, and the ventilation groove 101-1 is opened.
[0046] One end of the moving plate 2024 is fixed with an extension plate 2031, and the extension plate 2031 is fixed with a lifting plate 2032. When the temperature is too high, the expansion block 2023 drives the moving plate 2024, which can simultaneously drive the extension plate 2031 and the lifting plate 2032 to move.
[0047] The fixed block 2011 is provided with a second moving groove 2011-3, and the shell 101 can also be provided with a second moving groove 2011-3. The second moving groove 2011-3 is provided with a locking block 2033, and the baffle 2012 is provided with a locking groove 2012-1. The locking block 2033 is used to lock the position of the baffle 2012. When the locking block 2033 is engaged with the locking groove 2012-1, the position of the baffle 2012 in the sliding groove 2011-1 is locked. At this time, the baffle 2012 blocks the ventilation groove 101-1, and impurities and rainwater cannot enter the inside of the shell 101 from the ventilation groove 101-1.
[0048] Specifically, the locking block 2033 is provided with a stress groove 2033-1, and the lifting plate 2032 is inserted into the stress groove 2033-1.

[0050] When the temperature is too high, the expansion block 2023 expands to drive the moving plate 2024, which can simultaneously drive the extension plate 2031 and the lifting plate 2032 to move upward. The inclined surface 2032-1 of the lifting plate 2032 will press the stress groove 2033-1, so that the locking block 2033 moves along the second moving groove 2011-3 away from the locking groove 2012-1, and then separates from the locking groove 2012-1, so as to release the locking of the baffle 2012. The position of the baffle 2012 can be changed, so that the ventilation groove 101-1 is gradually opened.
[0051] The lifting plate 2032 is divided into two parts due to the existence of the inclined surface 2032-1, one part has a large cross-sectional area and the other part has a smaller cross-sectional area, and the part with a larger area has a longer length, thereby ensuring that it can adapt to the expansion of the expansion block 2023 and ensuring that the lifting plate 2032 can always be located in the stress groove 2033-1 during the expansion process.
[0052] Embodiment 3
[0053] With reference to Figures 1-8 As a third embodiment of the utility model, the embodiment is based on the previous two embodiments.
[0054] Specifically, the locking block 2033 is fixed on one side with the first spring 2034, and the other end of the first spring 2034 is fixed to the inner wall of the second moving groove 2011-3 on the shell 101, so as to exert a continuous pushing force on the locking block 2033 and ensure that the locking block 2033 can be engaged with the locking groove 2012-1.
[0055] When the expansion block 2023 expands, the lifting plate 2032 moves upward, so that the locking block 2033 is separated from the locking groove 2012-1, and at this time the first spring 2034 will be compressed.
[0056] When the temperature gradually decreases, the expansion block 2023 shrinks back to the initial state, driving the moving plate 2024, the extension plate 2031 and the lifting plate 2032 to move downward, and when the inclined surface 2032-1 no longer presses the stress groove 2033-1, the first spring 2034 restores, so that the locking block 2033 can be engaged with the locking groove 2012-1 again.
[0057] Specifically, the baffle 2012 is fixed on one side with the second spring 2016, and the other end of the second spring 2016 is fixed to the inner wall of the sliding groove 2011-1, so as to exert a continuous pushing force on the baffle 2012 and ensure that the baffle 2012 can block the ventilation groove 101-1. Under the action of no other external force, the second spring 2016 makes the baffle 2012 adhere to one of the end faces of the sliding groove 2011-1, at this time the ventilation groove 101-1 is blocked and will not assist in heat dissipation, and the baffle 2012 will also hinder impurities and rainwater from entering the inside of the projection lamp from the ventilation groove 101-1.
[0058] When the temperature in the shell 101 rises, when it reaches the expansion trigger temperature of the expansion block 2023, the expansion block 2023 will expand and push the moving plate 2024 to move along the first moving groove 101-2, while driving the extension plate 2031 and the lifting plate 2032 to move upward, so as to drive the baffle 2012 to move and open the ventilation groove 101-1 under the cooperation of the spiral groove 2014-1 and the clamping block 2015, at this time the second spring 2016 will be compressed.
[0059] When the temperature of the shell 101 gradually decreases, the expansion block 2023 will shrink until it returns to the initial state, in the process, the moving plate 2024, the extension plate 2031 and the lifting plate 2032 are driven to move downward, the moving plate 2024 no longer extrudes the rotating plate 2022, the second spring 2016 restores, and the rotating shaft 2014 reversely rotates, the baffle 2012 reversely moves, and the air passage 101-1 is closed, when the air passage 101-1 is completely closed, the rotating shaft 2014 no longer rotates, at this time, the locking block 2033 and the locking groove 2012-1 will be coaxial, but under the action of the lifting plate 2032, the two will not be engaged, and the expansion block 2023 has not returned to the initial position, the lifting plate 2032 can still continue to move downward, with the continuous movement of the lifting plate 2032, when the inclined surface 2032-1 of the lifting plate 2032 no longer extrudes the stress groove 2033-1, the first spring 2034 restores to make the locking block 2033 engaged with the locking groove 2012-1, thereby avoiding that the air passage 101-1 is accidentally opened under the action of external force.
[0060] Specifically, the shell 101 is provided with a cavity 101-3, the cavity 101-3 is communicated with the first moving groove 101-2 and the chamber 2011-2, the extension plate 2031 and the lifting plate 2032 are slidably arranged in the cavity 101-3, and when the rotating plate 2022 rotates with the rising of the moving plate 2024, the rotating plate 2022 will pass through the first moving groove 101-2, the cavity 101-3 and the chamber 2011-2, so as to ensure that the rotating plate 2022 can normally rotate.
[0061] Specifically, the shell 101 is movably connected with a cover plate 104, the cover plate 104 is connected with the shell 101 through bolts, the shell 101 is provided with a support frame 105, the support frame 105 is hinged with the shell 101, so as to adjust the irradiation angle, the two can be fixed through bolts, the shell 101 is fixed with a heat sink 204, the heat sink 204 improves the heat dissipation effect by increasing the heat dissipation area, which is prior art, and the working principle of the present scheme will not be described in detail, and those skilled in the art can clearly know the working principle.
[0062] In use, when the temperature in the shell 101 rises and reaches the expansion trigger temperature of the expansion block 2023, the expansion block 2023 will expand and push the moving plate 2024 to move along the first moving groove 101-2, while driving the extension plate 2031 and the lifting plate 2032 to move upward, the inclined surface 2032-1 of the lifting plate 2032 will extrude the stress groove 2033-1, so that the locking block 2033 moves along the second moving groove 2011-3 in a direction away from the locking groove 2012-1, and then separates from the locking groove 2012-1, so as to release the locking of the baffle 2012.
[0063] Afterwards, as the expansion block 2023 continues to expand, the moving plate 2024 moves upward, contacts the rotating shaft 2014, and pushes the rotating shaft 2014 to rotate, the rotating shaft 2014 drives the rotating disc 2021 to rotate, thereby making the rotating shaft 2014 rotate, when the rotating shaft 2014 rotates, the clamping block 2015 will slide in the spiral groove 2014-1, thereby driving the moving block 2013 to move along the direction of the rotating shaft 2014, thereby driving the baffle 2012 to move, thereby opening the ventilation groove 101-1, and assisting heat dissipation.
[0064] When the temperature in the shell 101 decreases, the expansion block 2023 shrinks, in the process, the moving plate 2024, the extension plate 2031 and the lifting plate 2032 are driven to move downward synchronously, the moving plate 2024 no longer extrudes the rotating plate 2022, the second spring 2016 restores, and the rotating shaft 2014 reversely rotates, the baffle 2012 reversely moves to the initial position, the ventilation groove 101-1 is closed again, and the lifting plate 2032 moves downward, when the inclined surface 2032-1 no longer extrudes the stressed groove 2033-1, the first spring 2034 restores, and the locking block 2033 and the locking groove 2012-1 can be clamped again, thereby locking the position of the baffle 2012, and avoiding that the ventilation groove 101-1 is accidentally opened under external force.
