Description

Technical Field

[0001] This utility model belongs to the field of outdoor decoration, and in particular relates to a ground projection device with protective function. Background Technology

[0002] In modern outdoor decoration, the demand for personalization and customization is increasing day by day. In order to improve the visual appeal of outdoor walls, carving is often carried out on the walls. However, carving is not only complex and expensive, but also has a poor viewing effect at night. Therefore, existing technology has proposed to use projection to project corresponding landscape images on the wall to be decorated. However, projectors are often affected by complex weather conditions in outdoor environments, which can lead to damage or malfunction.

[0003] In existing technologies, the projector is placed inside a protective housing and the projected image is displayed through a transparent window. However, the protective housing is quite conspicuous in many environments, affecting the overall aesthetics of the landscape. Furthermore, the transparent window is easily covered with dust and dirt, which leads to a decrease in the projection effect. Therefore, there is a need for a structure that can protect the projector, blend into the landscape environment, and does not require frequent cleaning. Utility Model Content

[0004] In view of this, the present invention aims to provide a ground projection device with protective function in order to solve at least one of the above-mentioned technical problems.

[0006] A ground projection device with protective function includes:

[0007] The housing is located at the installation position of the projection device, and a drive component for driving the protective components to rotate is fixed on the outside of the housing.

[0008] A protective assembly is located inside the housing and is hinged to the housing via a rotating shaft, which is fixedly connected to the power output end of the drive assembly. A projection device is located inside the protective assembly. A top cover corresponding to the housing is fixedly mounted on the protective assembly.

[0009] A transmission assembly is disposed inside the protection assembly and transmits the torque provided by the drive assembly to the opening and closing mechanism within the protection assembly.

[0010] Furthermore, the opening and closing mechanism includes:

[0011] The blades are provided in multiples, and an annular baffle with a variable inner diameter is formed between the multiple blades; each blade is fixed with a pair of limiting pins and a hinge shaft.

[0012] The driven disk has multiple limiting holes corresponding to the limiting pins, and a driven gear is fixed on the end face of the driven disk away from the blade.

[0013] The clamping ring has two clamping rings. The blade and the driven disk are located between the two clamping rings. The edge portion of the clamping ring is evenly provided with multiple connecting shafts along the circumference. Each connecting shaft is hinged to a drive rod. The end of the drive rod away from the connecting shaft is hinged to the hinge shaft.

[0014] Furthermore, the driven gear is fixedly connected to the driven disc by a connecting ring, and the outer wall of the connecting ring is in contact with the inner wall of the clamping ring.

[0015] Furthermore, the protection component is provided with a drive gear that meshes with the driven gear, and the drive gear is fixedly connected to the output end of the transmission component.

[0016] Furthermore, the blade is a triangular structure with a sliding groove on its sidewall and a sliding block fixed on an adjacent sidewall; the sliding block of the blade is located in the sliding groove of the adjacent blade.

[0017] Furthermore, the transmission assembly includes:

[0018] An output shaft is connected to an opening and closing mechanism to transmit the torque applied by the input shaft to the opening and closing mechanism. A first bevel gear is fixed at one end of the output shaft away from the opening and closing mechanism.

[0019] An input shaft is provided with a second bevel gear that meshes with a first bevel gear at one end and a sliding gear at the other end; the sliding gear receives the torque applied by the drive assembly and transmits it to the input shaft.

[0020] Furthermore, the protective component rotates along the rotation direction of the rotating shaft, the sliding gear moves along the moving direction of the protective component, and an arc-shaped rack is fixed on the inner wall of the housing. The arc-shaped rack meshes with the sliding gear and drives the sliding gear to rotate. The sliding gear transmits the torque generated by the rotation to the input shaft.

[0021] Furthermore, both the output shaft and the input shaft are rotatably connected to the protection assembly.

[0022] Compared with the prior art, the ground projection device with protective function described in this utility model has the following beneficial effects:

[0023] By submerging the housing into the installation location, the projection device can be integrated into the landscape environment. The housing and protective components provide protection for the projector.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] A ground projection device with protective function includes:

[0038] The housing 1 is located at the installation position of the projection device, and a drive component for driving the protective component 2 to rotate is fixed on the outside of the housing 1.

[0039] Protection component 2 is located inside housing 1 and is hinged to housing 1 via rotating shaft 201, which is fixedly connected to the power output end of the drive component. A projection device is located inside protection component 2. A top cover 4 corresponding to housing 1 is fixedly mounted on protection component 2.

[0040] The transmission component 3 is disposed inside the protection component 2 and transmits the torque provided by the drive component to the opening and closing mechanism 5 inside the protection component 2.

[0041] The opening and closing mechanism 5 includes:

[0042] The blades 501 are provided in multiple ways, and an annular baffle with a variable inner diameter is formed between the multiple blades 501; each blade 501 is fixed with a pair of limiting pins 502 and a hinge shaft 509.

[0043] Driven disk 503, the driven disk 503 has a plurality of limiting holes 504 corresponding to the limiting pin 502, and a driven gear 505 is fixed on the end face of the driven disk 503 away from the blade 501;

[0044] Clamping ring 506, two clamping rings 506 are provided, the blade 501 and the driven disk 503 are located between the two clamping rings 506, the edge portion of the clamping ring 506 is evenly provided with a plurality of connecting shafts 507 along the circumference, each connecting shaft 507 is hinged to a drive rod 508, and the end of the drive rod 508 away from the connecting shaft 507 is hinged to the hinge shaft 509.

[0045] In this embodiment, the opening and closing mechanism 5 is specifically an iris mechanism. This mechanism can also be replaced by other components that can realize the opening and closing function and correspond to the projector lens.

[0046] The driven gear 505 is fixedly connected to the driven disk 503 by a connecting ring, and the outer wall of the connecting ring is in contact with the inner wall of the clamping ring 506.

[0047] The protection component 2 is provided with a drive gear 202 that meshes with the driven gear 505, and the drive gear 202 is fixedly connected to the output end of the transmission component 3.

[0048] The blade 501 is a triangular structure. A sliding groove 511 is opened on the side wall of the blade 501, and a sliding block 510 is fixed on the adjacent side wall. The sliding block 510 of the blade 501 is located in the sliding groove 511 of the adjacent blade 501.

[0049] The transmission assembly 3 includes:

[0050] Output shaft 301 is connected to the opening and closing mechanism to transmit the torque applied by input shaft 302 to the opening and closing mechanism 5. A first bevel gear is fixed at one end of output shaft 301 away from the opening and closing mechanism 5.

[0051] An input shaft 302 is provided with a second bevel gear that meshes with a first bevel gear at one end and a sliding gear 303 at the other end; the sliding gear 303 receives the torque applied by the drive assembly and transmits it to the input shaft 302.

[0052] The protective component 2 rotates along the rotation direction of the rotating shaft 201, and the sliding gear 303 moves along the moving direction of the protective component 2. An arc-shaped rack 101 is fixed on the inner wall of the housing 1. The arc-shaped rack 101 meshes with the sliding gear 303 and drives the sliding gear 303 to rotate. The sliding gear 303 transmits the torque generated by the rotation to the input shaft 302.

[0053] Both the output shaft 301 and the input shaft 302 are rotatably connected to the protection component 2.

[0054] Work process:

[0055] When the ground projection device is turned on, the drive component drives the rotating shaft 201 to rotate, and the rotating shaft 201 drives the protection component 2 to rotate. At this time, the sliding gear 303 moves along the direction of motion of the rotating shaft 201 under the drive of the protection component 2. Because the sliding gear 303 meshes with the arc-shaped rack 101, the sliding gear 303 can move along the direction set by the arc-shaped rack 101 while completing axial rotation, thereby transmitting the torque generated by the axial rotation to the input shaft 302. The input shaft 302 further transmits the torque to the output shaft 301 that meshes with it. On the upper part, the output shaft 301 drives the drive gear 202 to rotate, the drive gear 202 drives the driven gear 505 meshing with it to rotate, the driven gear 505 drives the driven disk 503 to rotate, and the limiting pin 502 slides in the limiting hole 504 due to the rotation of the driven disk 503. At the same time, the drive rod 508 rotates around the connecting shaft 507 and restricts the movement of the blade 501 through the hinge shaft 509. As the driven disk 503 rotates, the distance between the multiple blades 501 increases or decreases, thereby completing the opening and closing of the opening and closing mechanism 5.
