Description

Technical Field

[0001] This utility model specifically relates to a projection robot projection screen adjustment system. Background Technology

[0002] Currently, projection equipment is widely used in home theaters, educational presentations, and commercial displays. Traditional projectors typically require users to manually adjust the position and angle to achieve the best projection effect, which is cumbersome and inefficient. Furthermore, most existing projection devices lack autonomous mobility, making them difficult to adapt to complex and changing application environments.

[0003] In recent years, with the development of robotics technology, some projection devices have begun to integrate mobile platforms, but they still have the following problems: the projection direction cannot be automatically corrected, which easily leads to skew or distortion; the image quality adjustment depends on manual intervention; and it is difficult to adapt to complex projection environments.

[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a projection robot projection screen adjustment system that is automatically adjustable and more applicable.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a projection robot projection screen adjustment system, including a robot for placement on a support. The robot includes a shell, and the shell is equipped with a projection device for projecting the image forward onto the object being projected. The bottom of the shell is equipped with a drive mechanism that enables it to move and rotate horizontally. The front of the shell is equipped with at least three distance sensors: a front-facing distance sensor, a left-facing distance sensor, and a right-facing distance sensor. The shell also contains a control module that is electrically connected to the drive mechanism and each sensor, thereby collecting distance information and controlling the operation of the drive mechanism.

[0008] As described above, the projection robot projection screen adjustment system includes a drive mechanism comprising two drive wheels rotatably connected to the bottom of the housing and correspondingly arranged thereon, and a drive device disposed inside the housing for individually driving the drive wheels to rotate.

[0009] As described above, the projection robot projection screen adjustment system also includes a rotatable auxiliary universal wheel at the bottom of the housing. The auxiliary universal wheel is located in front of the drive wheel and between the two drive wheels.

[0010] In the projection robot projection screen adjustment system described above, the left front distance sensor and the right front distance sensor are symmetrically arranged.

[0011] As described above, the projection robot projection screen adjustment system also includes an image collection device inside the housing that faces forward and is used to collect image information of the projected object.

[0012] As described above, the projection robot projection screen adjustment system also includes an energy storage battery inside the casing for power supply.

[0013] As described above, in the projection robot projection image adjustment system, the projection device is connected to a heat dissipation device for heat dissipation, and the side wall of the housing is provided with a heat dissipation area for heat dissipation, and the heat dissipation area is provided with several through holes.

[0014] As described above, the projection robot projection screen adjustment system also includes a cooling fan and a speaker that are positioned close to the heat dissipation area and are used to play sound.

[0015] As described above, the projection robot projection screen adjustment system has an anti-slip structure on the drive wheel column surface.

[0016] As described above, the projection robot projection screen adjustment system has a shield on the front side of the casing. The shield has a projection window for the projection device to emit light and a sensing window for the distance sensor signal to pass through. The projection window is covered with a light-transmitting projection cover plate, and the sensing window is covered with a light-transmitting sensing cover plate.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This system achieves fully automatic adjustment of the projected image, enhancing ease of use and intelligence. By setting up multiple distance sensors and image acquisition devices, combined with the control module, it can perceive and analyze environmental information in real time, automatically identify the position and direction of the projected object, and complete functions such as autonomous robot movement, alignment, distance adjustment, and image quality adjustment without user intervention, significantly improving the intelligence and ease of operation of the projection equipment.

[0019] 2. The structural design is compact and reasonable, taking into account both functionality and aesthetics. The system's structural design fully considers space utilization and product practicality. For example, the cooling fan and speaker share the same heat dissipation area through hole, the shielding plate protects the internal components while enhancing the overall appearance, and the drive wheels are equipped with an anti-slip structure to enhance movement stability. This makes the whole machine have a good sense of industrial design and market competitiveness while ensuring functional integrity.

[0020] 3. Adaptable to various application scenarios, with good environmental adaptability and expansion potential, this projection robot is not only suitable for various indoor scenarios such as home, education, and commerce, but can also further expand its functional boundaries through algorithm upgrades and module expansion (such as adding voice interaction, SLAM navigation, AR fusion, etc.), with strong versatility and scalability to meet the diverse needs of different users.

[0027] The utility model will be further described below with reference to the accompanying drawings:

[0028] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0029] This embodiment describes a projection robot projection image adjustment system, such as... Figure 1 As shown, it includes a robot 1 for placement on a support A. The robot 1 is placed on the support A with its front facing the object to be projected, which is generally a screen, but can also be a flat wall free of debris.

[0030] like Figure 2As shown, the system includes a robot 1 placed on a support. The robot 1 includes a housing 11, on which a projection device 12 is provided for projecting an image forward onto a projected object. The projection device 12 is an optical device that projects images or videos onto a flat surface such as a screen or wall using a light source and an optical system. For details, please refer to the patent scheme with patent number CN201820273153.7 and title "Projector and Projection Device".

[0031] like Figures 1 to 3 As shown, the bottom of the housing 11 is equipped with a drive mechanism 13 that enables it to move and rotate horizontally. Specifically, the drive mechanism 13 includes two drive wheels 131 rotatably connected to the bottom of the housing 11 and correspondingly arranged, and a drive device 132 disposed inside the housing 11 for individually driving the drive wheels 131 to rotate. The two drive devices 132 independently drive the two drive wheels 131 to rotate, thereby achieving horizontal movement by the two drive wheels 131 rotating in the same direction and achieving horizontal rotation by the two drive wheels 131 rotating in opposite directions, thus enabling the robot 1 to move to any position on the support A. Structural principle explanation: The differential drive method (i.e., independent dual-wheel drive) is one of the most widely used drive structures in mobile robots. When the speeds of the two wheels are the same, the robot moves forward in a straight line; when the speeds of the two wheels are opposite, the robot rotates around its own center. This structure is not only simple and fast-responding, but also facilitates the implementation of control algorithms.

[0032] The front of the housing 11 is provided with at least three distance sensors 14, namely a front-facing distance sensor 141 facing directly forward, a left-front distance sensor 142 facing to the left front, and a right-front distance sensor 143 facing to the right front. The housing 11 is also provided with a control module 15 that is electrically connected to the drive mechanism 13 and each sensor, thereby collecting distance information and controlling the operation of the drive mechanism 13.

[0033] Its working principle is as follows: Figure 6As shown, robot 1 moves on a flat support A by rotating two drive wheels 131, and can identify and avoid obstacles through three distance sensors 14. After reaching the front of the projected object B, robot 1 rotates horizontally and identifies the projected object B. The distance D1 between the projected object B and robot 1 is identified by the front distance sensor 141. Robot 1 moves to a distance closer to the front of the projected object B (e.g., 1-1.5 meters). Robot 1 rotates horizontally until the distance D2 identified by the left front distance sensor 142 and the distance D3 identified by the right front distance sensor 143 are the same, so that robot 1 is facing the projected object B. Then robot 1 moves away from the projected object B. During the process, when the reading of the left front distance sensor 142 changes abruptly, robot 1 moves to the right to adjust. When the reading of the right front distance sensor 143 changes abruptly, robot 1 moves to the left to adjust, until robot 1 moves to a suitable projection distance (a preset suitable projection distance, such as between 1.5 meters and 3 meters), so that robot 1 can automatically adjust to a more suitable projection position. By forming a triangular perception area through a three-sensor layout, the accuracy of environmental perception is improved, enabling automatic obstacle avoidance, automatic alignment, and automatic distance adjustment, reducing manual intervention. By using the left and right distance sensors to provide feedback on differences, precise direction correction is achieved, ensuring that the projected image is directly facing the target surface. It can adapt to projection surfaces of different sizes and positions, and has strong environmental adaptability.

[0034] Preferably, the position information of the projected object B can be preset in the control module 15 of robot 1, enabling robot 1 to move in front of the projected object B. In this embodiment, the housing 11 is also equipped with an image collection device 16 facing forward for collecting image information of the projected object. An identifier can be set on the projected object B. When robot 1 rotates, it recognizes the corresponding identifier to determine the position of the projected object B. Simultaneously, the image collection device 16 can collect image information projected onto the projected object B, and then analyze and calculate the projected image information to perform adjustments such as focus adjustment, keystone correction, and boundary fine-tuning. The image acquisition device can be a camera or other imaging device, combined with image processing algorithms to obtain the distortion of the projected image in real time. For example, if blurred edges are detected, autofocus is activated; if keystone distortion is detected, digital correction is enabled; if the image does not completely cover the target area, the projection angle is adjusted or the robot position is moved.

[0035] As a preferred option, such as Figure 1As shown, the bottom of the housing 11 is also equipped with a rotatable auxiliary caster wheel 133. The auxiliary caster wheel 133 is located in front of the drive wheel 131 and between the two drive wheels 131, so that the horizontal movement and rotation of the robot 1 are smoother and more stable. The auxiliary caster wheel plays a supporting and guiding role, reducing frictional resistance during robot movement, especially reducing energy loss and wear caused by sliding when turning.

[0036] For ease of identification and calculation, the left front distance sensor 142 and the right front distance sensor 143 are symmetrically arranged. Of course, asymmetry is also acceptable; given the angle of their tilt, correction can be made through calculation.

[0037] Preferably, the housing 11 is also provided with an energy storage battery 17 for power supply.

[0038] Preferably, the projection device 12 is connected to a heat dissipation device 18. The side wall of the housing 11 has a heat dissipation area 111 with several through holes 112. Furthermore, the housing 11 also contains a cooling fan 113 positioned against the heat dissipation area 111 and a speaker 114 positioned against the heat dissipation area 111 for sound transmission. The cooling fan 113 and speaker 114 share the same through holes 112 in the heat dissipation area 111, enhancing both the product's compactness and overall aesthetics. The cooling fan 113 draws in cool air and exhausts hot air through the through holes 112, achieving active cooling; while the speaker 114 uses the same set of through holes for sound transmission, avoiding the need for additional openings that could compromise the housing's sealing and structural strength.

[0039] Preferably, the drive wheel 131 has an anti-slip structure 134 on its cylindrical surface. The anti-slip structure can be a rubber coating, raised texture, or groove design, designed to enhance the friction between the tire and the ground and prevent slippage, especially on smooth floors or slopes.

[0040] Preferably, a baffle plate 115 is provided on the front side of the housing 11. The baffle plate 115 has a projection window 116 for light to be emitted from the projection device 12 and a sensing window 117 for the distance sensor signal to pass through. A light-transmitting projection cover plate 118 is provided on the projection window 116, and a light-transmitting sensing cover plate 119 is provided on the sensing window 117. The projection cover plate 118 and the sensing cover plate 119 can be made of high-strength transparent material, which can protect the internal components from dust and impact without affecting the penetration of light and sensing signals.

[0041] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
