Description

Technical Field

[0001] This utility model relates to the field of projection equipment technology, specifically to an immersive panoramic projection device. Background Technology

[0002] A projector is a device that projects images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc., through different interfaces to play corresponding video signals. A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can use transmitted light for outline measurement, and it can also use reflected light to measure the surface shape of blind holes and observe the surface of parts. Immersive projection is a surrounding projection system that is an extension of holographic stereoscopic projection system. It generally consists of a cube structure composed of four projection surfaces, giving the audience the feeling of being inside.

[0003] Publication No. CN215596808U discloses an immersive panoramic projection device. The device is activated via an external remote control. An infrared remote control module starts the motor, which drives a transmission gear to rotate. Simultaneously, the transmission gear drives a driven gear, which in turn drives a lead screw via a connecting rod. The lead screw, passing through a threaded groove, causes a moving rod to move upwards within a support column. The moving rod also drives a sliding sleeve to move along a slide rail within a groove, thus moving the projector. Disassembly is simple: a tool is used to manually loosen the mounting screw, allowing the projector, along with its mounting slot, to be manually removed for maintenance. However, this patent has the following problems in practical use:

[0004] Although this immersive panoramic projection device allows for height adjustment of the projector via a motor and infrared remote control module, and can be disassembled using mounting screws, it does not allow for multi-angle adjustment of the projector, thus affecting the projection effect. In some special environments, it is necessary to adjust the angle of the projector to improve the clarity of the projected image. Furthermore, prolonged rotation of the mounting screws may damage the threads, which would prevent the projector from being fixed in place, affecting the installation effect.

[0005] Therefore, an immersive panoramic projection device is proposed to solve the problems mentioned above. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: an immersive panoramic projection device, including a projection protection mechanism and a projector installed inside the projection protection mechanism;

[0008] The top of the projection protection mechanism is provided with an adjustment mechanism, and the top of the adjustment mechanism is provided with a sliding bracket.

[0009] Also includes:

[0010] The projection protection mechanism includes a protective box, inside which a clamping base plate is fixedly installed, and clamping rotating rods are symmetrically rotatably connected to both sides of the clamping base plate.

[0011] The clamping rotating rod has a clamping sliding sleeve rotatably connected to its end, and the clamping sliding sleeve has a clamping sliding rod slidably connected inside it.

[0012] A clamping bracket is fixedly installed on the outer side of the clamping sliding rod, and a clamping spring is fixedly installed on one side of the clamping sliding sleeve.

A compression spring is rotatably connected to the end of the clamping threaded rod, and a clamping fixing plate is fixedly installed at the end of the compression spring. The projector is in close contact with the clamping fixing plate.

[0014] Preferably, the protective box has protective windows symmetrically installed on its front side. An unfolding motor is fixedly installed on the inner side of the protective box near the protective window. A sprocket drive assembly is fixedly connected to the output end of the unfolding motor. Two unfolding bidirectional threaded rods are symmetrically installed at both ends of the sprocket drive assembly.

[0018] Preferably, a locking bracket is fixedly installed on the top inner side of the sliding bracket, a locking knob is rotatably connected to the bottom center position of the locking bracket, a locking gear is fixedly installed on the top of the locking knob, locking pins are meshed on both sides of the locking gear, a pin limiting slide rail is slidably connected to the outer side of the locking pin, the pin limiting slide rail is fixedly installed inside the locking bracket, and the locking pin is engaged with the sliding bracket through a fixed insertion hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This immersive panoramic projection device, by pressing the clamping bracket under the action of the clamping rotating rod, causes the clamping rotating rod to rotate, thereby driving the clamping sliding sleeve and the clamping bracket to move relative to each other. This allows the clamping fixing plate to be unfolded and the projector to be placed in the middle of the clamping fixing plate. Through the elastic force of the clamping spring, the relative movement of the clamping sliding plate can be achieved when the clamping bracket is released, thus clamping and fixing the projector.

[0020] 1. By setting up a projection protection mechanism, not only can the projector be safely protected by the protective box, extending its service life, but also, by pressing the clamping bracket and rotating the clamping rod, the clamping rotating rod rotates, causing the clamping sliding sleeve and clamping bracket to move relative to each other. This unfolds the clamping fixing plate, allowing the projector to be placed in the center of the clamping fixing plate. Through the elastic force of the clamping spring, the relative movement of the clamping sliding plate is achieved when the clamping bracket is released, thus clamping and fixing the projector. By rotating the clamping threaded rod, the spacing of the clamping fixing plate can be adjusted, and the clamping stability of the projector is achieved through the elastic force of the compression spring. By starting the unfolding motor, the sprocket transmission assembly and the unfolding bidirectional threaded rod rotate, causing the unfolding threaded sleeve to move relative to the unfolding plate, realizing the unfolding and closing of the protective box, facilitating the placement and protection of the projector.

[0021] 2. By setting up an adjustment mechanism, not only can the horizontal rotation angle of the projector be adjusted by using a rotating motor to drive the adjustment base to rotate, but the adjustment motor also drives the adjustment threaded rod to rotate, which in turn drives the adjustment rotating rod to rotate. Under the action of the connecting hinge, the vertical angle of the projector can be adjusted. Through the sliding connection between the sliding bracket and the fixed bracket, the height of the projector can be adjusted. Through multi-angle and height adjustments, the projection clarity of the projector can be improved. By rotating the locking knob, the locking gear is driven to rotate. Utilizing the meshing connection between the locking pin and the locking gear, the locking pin slides relative to the pin limit slide rail. Utilizing the engaging connection between the locking pin and the fixed socket, the sliding bracket can be fixed. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6This utility model provides a technical solution: an immersive panoramic projection device, including a projection protection mechanism 1 and a projector 112 installed inside the projection protection mechanism 1. An adjustment mechanism 2 is provided on the top of the projection protection mechanism 1, and a sliding bracket 209 is provided on the top of the adjustment mechanism 2. The projection protection mechanism 1 includes a protective box 101, and a clamping base plate 102 is fixedly installed inside the protective box 101. Clamping rotating rods 103 are symmetrically rotatably connected to both sides of the clamping base plate 102. A clamping sliding sleeve 104 is rotatably connected to the end of each clamping rotating rod 103, and a clamping sliding rod 105 is slidably connected inside the clamping sliding sleeve 104. A clamping bracket 106 is fixedly installed on the outer side of the protective box 101. A clamping spring 107 is fixedly installed on one side of the clamping sliding sleeve 104. A clamping sliding plate 108 is fixedly installed on the outer side of the clamping sliding sleeve 104.

Symmetrically mounted on both ends of the sprocket drive assembly 115 are two unfolding bidirectional threaded rods 116. Expanding threaded sleeves 117 are symmetrically threaded onto the outer sides of each of the two unfolding bidirectional threaded rods 116. An unfolding plate 118 is fixedly installed between the two unfolding threaded sleeves 117. The protective box 101 provides safety protection for the projector 112, improving its service life. Simultaneously, by pressing the clamping bracket 106, under the action of the clamping rotating rod 103, the clamping rotating rod 103 rotates, causing the clamping sliding sleeve 104 and the clamping bracket 106 to move relative to each other. This unfolds the clamping fixing plate 111, allowing the projector 112 to be deployed. Placed in the middle of the clamping and fixing plate 111, the projector 112 is clamped and fixed by the relative movement of the clamping sliding plate 108 when the clamping bracket 106 is released due to the elastic force of the clamping spring 107. The distance between the clamping and fixing plates 111 can be adjusted by rotating the clamping threaded rod 109, and the projector 112 is clamped and fixed by the elastic force of the compression spring 110. The projector 112 is clamped and fixed by the relative movement of the clamping and fixing plate 118 driven by the expansion motor 114, which drives the sprocket transmission assembly 115 and the expansion bidirectional threaded rod 116 to rotate, so that the expansion threaded sleeve 117 drives the expansion plate 118 to move relative to each other, thereby realizing the expansion and closing of the protective box 101, which facilitates the placement and protection of the projector 112.

[0031] The adjustment mechanism 2 includes an adjustment fixing plate 201. A rotary motor 202 is fixedly installed at the top center of the adjustment fixing plate 201. An adjustment base 203 is fixedly connected to the output end of the rotary motor 202. An adjustment motor 204 is fixedly installed on one side of the adjustment base 203.

An adjustment rotating rod 207 is rotatably connected to the outer side of the adjustment threaded sleeve 206. A connecting hinge 208 is fixedly installed on one side of the bottom of the adjustment base 203. The connecting hinge 208 and the adjustment rotating rod 207 are connected together. All 07 are rotatably connected to the protective box 101. The sliding bracket 209 is fixedly installed on the top of the adjusting plate 201. The sliding bracket 209 is slidably connected to the fixed bracket 210. The fixed bracket 210 has a fixed insertion hole 211 on its inner side. The fixed top plate 212 is fixedly installed on the top of the fixed bracket 210. The fixed top plate 212 is symmetrically threaded with fixing bolts 213. The top inner side of the sliding bracket 209 is fixedly installed with a locking bracket 214. The bottom center of the locking bracket 214 is rotatably connected with a locking knob 215. The top of the locking knob 215 is fixedly installed with a locking gear 21. 6. Locking pins 217 are meshed on both sides of locking gear 216. A pin-limiting slide rail 218 is slidably connected to the outer side of locking pin 217. The pin-limiting slide rail 218 is fixedly installed inside locking bracket 214. Locking pin 217 is engaged with sliding bracket 209 through fixed insertion hole 211. The rotating motor 202 drives the adjusting base 203 to rotate, adjusting the horizontal rotation angle of projector 112. Simultaneously, the adjusting motor 204 drives the adjusting threaded rod 205 to rotate, causing the adjusting threaded sleeve 206 to drive the adjusting rotating rod 207 to rotate. Under the action of connecting hinge 208, the projector 112 can be adjusted. The vertical angle adjustment of the projector 112 is achieved by sliding the sliding bracket 209 and the fixed bracket 210. This allows for height adjustment of the projector 112, thereby improving the projection clarity of the projector 112 through multi-angle and height adjustments. By rotating the locking knob 215, the locking gear 216 is rotated. Utilizing the meshing connection between the locking pin 217 and the locking gear 216, the locking pin 217 slides relative to the pin limiting slide rail 218. By utilizing the engaging connection between the locking pin 217 and the fixed socket 211, the sliding bracket 209 can be fixed.

[0032] Working principle: Before using this immersive panoramic projection device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, firstly, the protective case 101 is used to protect the projector 112 and improve its service life. Simultaneously, by pressing the clamping bracket 106, the clamping rotating rod 103 rotates, causing the clamping sliding sleeve 104 and the clamping bracket 106 to move relative to each other. This unfolds the clamping fixing plate 111, allowing the projector 112 to be placed in the center of the clamping fixing plate 111. Then, through the elastic force of the clamping spring 107, the clamping bracket is released. At position 106, the relative movement of the clamping sliding plate 108 can be achieved, thereby clamping and fixing the projector 112. By rotating the clamping threaded rod 109, the spacing of the clamping fixing plate 111 can be adjusted, and the clamping stability of the projector 112 is achieved under the elastic force of the compression spring 110. By starting the unfolding motor 114, the sprocket transmission assembly 115 and the unfolding bidirectional threaded rod 116 are driven to rotate, causing the unfolding threaded sleeve 117 to drive the unfolding plate 118 to move relative to each other, thus realizing the clamping and fixing of the protective box 101. The opening and closing mechanism facilitates the placement and protection of the projector 112. Secondly, the rotating motor 202 drives the adjusting base 203 to rotate, adjusting the horizontal rotation angle of the projector 112. Simultaneously, the adjusting motor 204 drives the adjusting threaded rod 205 to rotate, causing the adjusting threaded sleeve 206 to drive the adjusting rotating rod 207 to rotate. Under the action of the connecting hinge 208, the vertical angle of the projector 112 can be adjusted. Through the sliding connection between the sliding bracket 209 and the fixed bracket 210, the height of the projector 112 can be adjusted. Through multi-angle and height adjustments, the projection clarity of the projector 112 is improved. Rotating the locking knob 215 drives the locking gear 216 to rotate. Utilizing the meshing connection between the locking pin 217 and the locking gear 216, the locking pin 217 slides relative to the pin limiting slide rail 218. Utilizing the engaging connection between the locking pin 217 and the fixed socket 211, the sliding bracket 209 can be fixed.
