Description
Technical Field
[0001] The utility model relates to the technical field of projection equipment, in particular to a vehicle-mounted projection platform. Background Art
[0002] With the development of multimedia technology, projection equipment has been widely used in various occasions. However, most projection equipment is fixed or handheld, which is not suitable for use in vehicles. In some special cases, such as outdoor performances, vehicle-mounted advertising displays, etc., a projection device that can be used stably in a vehicle is required, so a pan / tilt head is used to provide better stability for the projection equipment, making the use of the projection equipment better.
[0003] The traditional projection PTZ is characterized by its large size and heavy mass, which requires special attention and measures when installing and fixing it. Therefore, in existing vehicle-mounted applications, the projection PTZ is often fixed on the top of the vehicle, based on its weight and volume considerations to ensure stability and safety during vehicle driving.
[0004] However, due to the particularity of the structure and design of the top of the vehicle, its spatial layout is often compact and has limited height. Under such conditions, the installation team needs to use special tools or equipment, such as lifts, professional clamps, etc., when installing the projection device to ensure the accurate placement and fixation of the equipment. This specific installation measure not only increases the technical complexity of the entire installation process, but also places higher requirements on the professional skills and operating experience of the installers. In addition, the operating space on the top of the vehicle is small and the height is high. When the installers are working, they need to be in a high and narrow operating environment for a long time, which increases the risk of the operation. Utility Model Content

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-5 The utility model provides a technical solution for a vehicle-mounted projection platform:
[0031] The invention comprises a stabilizing device 1 and a projection device 2. The projection device 2 and the stabilizing device 1 are rotatably mounted with four support rods 302 at the bottom of the stabilizing device 1. A support leg 301 is inserted into the support rod 302. A guide line groove is provided on the surface of the support leg 301. A joint rod 308 is provided at the lower end of the support leg 301. A connecting seat 313 is provided at the lower end of the joint rod 308. A suction cup 316 is fixedly mounted on the connecting seat 313. By sucking the suction cup 316 on the inner wall of the trunk of the vehicle, the projection gimbal can be raised by the suction cup 316. The stability after fixation, and the vehicle will not be damaged during the process of fixing the projection gimbal, the support rod 302 is rotatably connected with a second threaded sleeve 307, the second threaded sleeve 307 is threadedly connected with the surface of the support leg 301, the second threaded sleeve 307 can make the support leg 301 extend from the inside of the support rod 302, so that the support leg 301 is against the inner wall of the trunk of the vehicle, so as to fix the projection gimbal, without fixing the projection gimbal on the top of the vehicle, improving the convenience and safety of using the projection gimbal;
[0032] Among them, both ends of the joint rod 308 are provided with spheres, and the two spheres on the joint rod 308 respectively form a ball-and-socket structure with the support foot 301 and the connecting seat 313. Through the joint rod 308 and the ball-and-socket assembly composed of the support foot 301 and the connecting seat 313, the suction cup 316 can be rotated at multiple angles. When facing an uneven vehicle trunk, the angle of the suction cup 316 can be adjusted so that the suction cup 316 can be better adsorbed on the vehicle trunk. The connecting seat 313 is fixedly connected to the second connecting frame 3 14, a bearing 309 is installed on the connecting seat 313, and a first connecting frame 310 is fixedly connected to the surface of the bearing 309. An extension frame 311 is inserted into the short arm ends of the first connecting frame 310 and the second connecting frame 314. A steel wire 312 is fixedly connected to the lower end of the extension frame 311. By pulling and tightening the steel wire 312, the steel wire 312 can be squeezed into the gap between the suction cup 316 and the trunk of the vehicle, so that one side of the suction cup 316 is tilted, so that air enters the suction cup 316, which can achieve the suction cup 316. The purpose of the plate 316 being quickly detached from the trunk of the vehicle is to achieve the rapid disassembly of the projection pan head. The position of the steel wire 312 is parallel to the bottom surface of the suction cup 316. A drooping rod is fixedly connected to the first connecting frame 310. Two springs 315 are fixedly connected to the drooping rod on the first connecting frame 310. Two blocking rods are fixedly connected to the connecting seat 313. The two springs 315 are located between the drooping rod on the first connecting frame 310 and the two blocking rods on the connecting seat 313. In the process of tightening the steel wire 312 rope through the first connecting frame 310, the spring 315 located in the rotation direction will be in a compressed state, and the spring 315 located in the opposite rotation direction will be in a stretched state. Therefore, when the suction cup 316 is detached from the first connecting frame 310, the first connecting frame 310 is released, and the spring 315 can be used to drive the first connecting frame 310 back to its original position and the steel wire 312 is returned to its original position at the same time, so as to prevent the steel wire 312 from being located below the suction cup 316 and affecting the use of the suction cup 316 when the suction cup 316 is used next time.
[0033] Among them, a thread groove 304 is provided on the surface of the support foot 301, and a first thread sleeve 306 is provided on the surface of the thread groove 304. The forked bracket 303 can be pushed by the first thread sleeve 306. Two forked brackets 303 are welded on the first thread sleeve 306. The forked bracket 303 can play a supporting role when the projection gimbal is placed on the ground to prevent the suction cup 316 from contacting the ground and causing the suction cup 316 to be worn or stained, thereby affecting the use of the suction cup 316. The lower end of the forked bracket 303 is rotatably connected to a supporting foot pad 305. The rotatable supporting foot pad 305 can make the projection gimbal better fit with the ground when it is placed on the ground, thereby improving the stability of the projection gimbal and providing better anti-slip performance.
[0034] When in use, the projection platform is placed in the trunk of the vehicle, and then the two corresponding support rods 302 and the support legs 301 are extended in parallel, and then the second threaded sleeve 307 is rotated to gradually extend the support legs 301 from the inside of the support rods 302, until the high-viscosity suction cups 316 on the two support legs 301 are tightly attached to the two sides of the inner wall of the trunk of the vehicle, which not only ensures that the projection platform can be firmly fixed in the trunk, but also avoids any potential damage to the vehicle caused by improper fixing methods. The suction cups 316 can ensure that they can provide strong adsorption force, thereby improving the stability of the projection platform fixation and effectively preventing the projection platform from shifting or falling off.
[0035] When the projection head needs to be disassembled, the first connecting frame 310 is rotated to accurately pull the steel wire 312 on the corresponding side until it is smoothly pulled into the gap under the suction cup 316, so that the suction cup 316 can be quickly detached, thereby greatly simplifying the disassembly process. The entire fixing and disassembly process reflects a high degree of professionalism and precision, ensuring the stable fixing and convenient disassembly of the projection head in the trunk of the vehicle, providing users with an excellent user experience.
[0036] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
