[0002] With the improvement of urban beautification and the quality of life of residents, garden lights are widely used as outdoor lighting equipment in private residential areas, parks and green spaces, and various public spaces. When the common garden lights on the market are being repaired, it is usually required to open the upper cover of the lamp to inspect the internal components. After opening, the upper cover tends to close automatically due to its own gravity. This requires maintenance personnel to allocate some energy and physical strength to manually support the upper cover when performing maintenance work to ensure that it remains in an open state. This operation method not only significantly increases the workload of maintenance personnel and reduces work efficiency, but also limits their freedom to operate tools because their hands are occupied, further affecting the accuracy and comfort of maintenance work.

[0003] When garden lights are installed at a higher position, maintenance personnel need to manually support the upper cover while performing high-altitude operations to repair the lamps. The complex working conditions greatly increase the difficulty of operation, making maintenance personnel face higher labor intensity and safety risks. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Example 1

[0034] Combination Figure 1 , Figure 6 and Figure 7 As shown, the automatic cover opening mechanism of the utility model is schematically shown, including a first shell 10, a second shell 20, a support assembly 30 and an elastic member 40. The first shell 10 and the second shell 20 are movably connected, so that the first shell 10 and the second shell 20 can be opened or closed, and the two move toward each other or rotate forward to close, and the two move away from each other or rotate backward to open. Taking this embodiment as an example, the first shell 10 is hinged to the second shell 20.

[0035] Specifically, the support assembly 30 includes a first support member 31 and a second support member 32 that are movably connected. The first support member 31 is connected to the first housing 10, and the second support member 32 is connected to the second housing 20. Both ends of the elastic member 40 are connected to the first support member 31 and the second support member 32, respectively.

[0036] The first support member 31 and the second support member 32 are driven by the elastic force of the elastic member 40 so that the first shell 10 and the second shell 20 have a tendency to move in opposite directions. Therefore, when the first shell 10 and the second shell 20 are opened, the elastic force of the elastic member 40 can keep the first shell 10 and the second shell 20 open without the need for maintenance personnel to manually support the first shell 10 and the second shell 20 to keep them open. When the first shell 10 and the second shell 20 need to be closed, the first shell 10 and the second shell 20 are manually pressed to rotate them in opposite directions, and the elastic force of the elastic member 40 needs to be overcome. Of course, an existing buckle can be provided between the first shell 10 and the second shell 20 as needed to keep the first shell 10 and the second shell 20 closed.

[0037] In this embodiment, the first support member 31 and the second support member 32 can be rotatably connected, that is, one end of the first support member 31 is connected to the first shell 10, and the other end of the first support member 31 is rotatably connected to one end of the second support member 32, and the other end of the second support member 32 is connected to the second shell 20. The elastic member 40 can preferably be a torsion spring, and the two ends of the elastic member 40 are respectively connected to the first support member 31 and the second support member 32. The elastic torsion force of the torsion spring drives the first support member 31 and the second support member 32 to rotate relative to each other and forces the first shell 10 and the second shell 20 to rotate in opposite directions to open.

[0038] Example 2

[0039] Combination Figure 1 and Figure 5As shown, the difference between this embodiment and embodiment 1 is that the second support member 32 is a cylindrical structure, the first support member 31 is slidably arranged in the second support member 32, the first support member 31 is rotatably connected to the first shell 10, the second support member 32 is rotatably connected to the second shell 20, and the elastic member 40 is preferably a spring. When the first shell 10 and the second shell 20 rotate in the opposite direction to open, the first support member 31 extends from the second support member 32, that is, the support assembly 30 extends, and when the first shell 10 and the second shell 20 rotate forward to close, the first support member 31 shrinks into the second support member 32, and at this time, the elastic force of the elastic member 40 needs to be overcome, that is, the support assembly 30 shrinks. This structure can also achieve support for the first shell 10 and the second shell 20.

[0040] It should be noted that the first support member 31 can be directly slidably connected to the second support member 32, or the first support member 31 can be indirectly slidably connected to the second support member 32. In other words, several levels of slide rail and slider mechanisms can be set between the first support member 31 and the second support member 32 to achieve an indirect sliding connection between the first support member 31 and the second support member 32. For example, a two-level slide rail and slider mechanism is set, and each level of the slide rail and slider mechanism includes a slide rail and a slider that are slidably connected, wherein the slider of the first level of the slide rail and slider mechanism is set on the first support member 31, and the slide rail is fixedly connected to the slider of the other level of the slide rail and slider mechanism, and the slide rail of the other level of the slide rail and slider mechanism is set on the second support member 32, so as to achieve an indirect sliding connection between the first support member 31 and the second support member 32.

[0041] Example 3

[0042] Combination Figure 3 As shown, the difference between this embodiment and embodiment 2 is that the support assembly 30 further includes a third support member 33 of a cylindrical structure, the third support member 33 is located between the first support member 31 and the second support member 32, the inner diameter of the second support member 32 is larger than the outer diameter of the third support member 33, and the outer diameter of the third support member 33 is larger than the inner diameter of the first support member 31. The third support member 33 is slidably disposed in the second support member 32, and the first support member 31 is slidably disposed in the third support member 33. The multi-stage telescopic cylinder structure composed of the first support member 31, the second support member 32 and the third support member 33 can achieve a longer telescopic stroke of the support assembly 30.

[0043] The first support member 31 is a cylindrical structure, one end of the elastic member 40 is located in the first support member 31, and the other end of the elastic member 40 is located in the second support member 32. Of course, the elastic member 40 is inserted into the third support member 33. The elastic member 40 is built into each support member to protect the elastic member 40. In other optional embodiments, the elastic member 40 can also be sleeved outside the first support member 31 and the second support member 32.

[0044] like Figure 4 and Figure 5 In order to limit the travel between the support members, a first limit block 311 is provided on the outer wall surface of the first support member 31, a second limit block 331 is provided on the inner wall surface of the third support member 33 and is arranged opposite to the first limit block 311, a third limit block 332 is provided on the outer wall surface of the third support member 33, and a fourth limit block 321 is provided on the inner wall surface of the second support member 32 and is arranged opposite to the third limit block 332. When the support assembly 30 switches to the extended state, the first limit block 311 and the second limit block 331 abut against each other, and the third limit block 332 and the fourth limit block 321 abut against each other, so as to prevent the first support member 31 from falling out of the third support member 33 and the third support member 33 from falling out of the second support member 32.

[0045] Furthermore, the first support member 31 can be slidably inserted into one end of the second support member 32, and the other end of the second support member 32 is detachably connected to the base 34. Preferably, the second support member 32 and the base 34 are connected by a threaded connection, and the end of the elastic member 40 abuts against the base 34. The base 34 can be removed from the second support member 32 to remove the elastic member 40, so as to facilitate the inspection and replacement of the elastic member 40.

[0046] In order to make the first shell 10 and the second shell 20 open more smoothly under the elastic force of the elastic member 40, the automatic cover opening mechanism also includes a damper, the two ends of which are respectively connected to the first shell 10 and the second shell 20. After the damper is set, the first shell 10 and the second shell 20 rotate in opposite directions to open under the elastic force of the elastic member 40, and the damper provides resistance to make the rotation between the first shell 10 and the second shell 20 smoother.

[0047] Example 3

[0048] In order to solve the same technical problem, this embodiment discloses a lamp, including the automatic cover opening mechanism as described above, and a light-emitting element can be arranged in the first shell 10 or the second shell 20 to provide a lighting function.

[0049] To summarize, the first support member 31 and the second support member 32 are movably connected, and the two are respectively connected to the first shell 10 and the second shell 20, and the two ends of the elastic member 40 are respectively connected to the first support member 31 and the second support member 32. The elastic force of the elastic member 40 drives the first shell 10 and the second shell 20 to move away from each other through the first support member 31 and the second support member 32, so that the first shell 10 and the second shell 20 remain open, and there is no need for maintenance personnel to manually support the first shell 10 and the second shell 20, which improves the user experience and greatly reduces the safety risks faced by maintenance personnel.
