Embodiment Construction

[0023] figure 1 A longitudinal sectional view of an actuating device according to a first embodiment of the invention is shown. A first elastic body 3, an actuating member 5 and a second elastic body 4 are sequentially installed in the housing 2, which is preferably designed as a sleeve, wherein one end of the actuating member 5 protrudes from the housing 2 in the longitudinal direction. The upper groove 7 and the transmission member 6 are movably connected. The first and second elastic body 3, 4 are preferably designed as springs, the first elastic body 3 is located between the top surface of the housing 2 and the actuator 5 under pressure; the second elastic body 4 is located in the housing under pressure 2 and the actuator 5, so the actuator 5 can be fixedly clamped between the first and second elastic bodies 3, 4. exist figure 1 Among them, the first elastic body 3 applies a vertically downward first elastic force F1 to the actuating member 5 , and the second elastic bo...

Abstract

The invention relates to an actuating device (1) used for devices with a heat source (10), which comprises a casing (2), a first elastomer (3) and a second elastomer (4) that are accommodated in the casing (2), an actuating part (5), as well as a transmission part (6), wherein the actuating part (5) is arranged between the first elastomer (3) and the second elastomer (4); and one end of the actuating part (5) is movably connected with one end of the transmission part (6). The actuating device (1) is characterized in that the elastic force of the first elastomer (3) and / or the second elastomer (4) can be changed by means of temperature and the actuating part (5) is prompted to move linearly in the casing (2) to control the position of the transmission part (6). The actuating device (1) has the advantages of small size, high reliability, simple structure, low cost, and less noise produced during the working. Besides, the invention further provides a cover plate component provided with the actuating device, as well as a lighting device equipped with the cover plate component.

Description

technical field [0001] The invention relates to an actuation device for a device with a heat source, a cover assembly with the actuation device and a lighting device equipped with the cover assembly. Background technique [0002] As electronic devices, especially lighting devices, are more and more widely used in people's daily life, heat dissipation has also become an important factor affecting the development of this field. The quality of the heat dissipation effect can directly affect the life and light effect of the lighting device. Usually, some lighting devices, such as high-power LED lighting devices, have an external heat sink, but this heat sink is limited by ID (industrial design) or external contour design, and is not easy to maintain. Another part of the lighting device has a cooling body integrated inside the casing, but the casing will hinder air convection at the same time, reducing the heat dissipation effect. [0003] In order to solve the above problems, ...
