Description

Technical Field

[0001] This utility model specifically relates to a movable shell structure for a projection robot. Background Technology

[0002] With the continuous development of smart projection devices, users have placed higher demands on the functionality, portability, and interactive experience of projection robots. In recent years, various projection devices with angle adjustment functions have emerged on the market to adapt to projection needs at different heights and angles. The applicant has also developed a projection robot that can adjust the projection angle by rotating the stand up and down, thereby improving projection flexibility and ease of use.

[0003] However, in practical use, ensuring the overall appearance, internal structural sealing, and multi-module integration of the device while achieving projection angle adjustment has become a pressing technical challenge. Traditional projection devices typically employ a fixed outer shell structure, which can easily lead to gaps and structural exposure when the projection angle changes, affecting the product's aesthetics and protective performance. Furthermore, projection robots, when integrating projection, display, sensing, heat dissipation, and audio output modules, often suffer from complex structural layouts, low space utilization, and inconvenient assembly and maintenance, limiting the product's intelligent development and the improvement of user experience.

[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 compact, protective movable shell structure for projection robots.

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

[0007] This utility model provides a movable shell structure for a projection robot, including a robot. The robot includes a shell, and a projection bracket that can rotate around a pivot P is provided inside the shell. The projection bracket is provided with a projection device for projecting an image forward. A drive device for driving the projection bracket to rotate is provided between the shell and the projection bracket. An arc-shaped sliding window is provided at the front of the shell. An arc-shaped sliding cover plate that can cover the sliding window is connected to the projection bracket. The centers of the sliding cover plate and the sliding window are both located on the pivot P, so that the sliding cover plate slides against the edge of the sliding window when the projection bracket rotates. A projection window for the projection device to emit light is provided on the sliding cover plate.

[0008] As described above, the movable outer shell structure of the projection robot is composed of a bottom shell and an upper shell. The bottom shell has a lower recess, and the upper shell has an upper recess. The lower recess and the upper recess are connected to form the sliding window.

[0009] As described above, the movable outer shell structure of the projection robot has a first limiting plate located on both sides of the sliding cover on the inner side of the bottom shell, and a second limiting plate located on both sides of the sliding cover on the inner side of the upper shell.

[0010] As described above, the movable outer shell structure of the projection robot has a lower arc recess on the bottom shell and an upper arc recess on the upper shell. A display component is provided between the bottom shell and the upper shell to cover the lower arc recess and the upper arc recess. The display component, the bottom shell, and the upper shell together form a spherical shell. The display component is provided with a display device that can display light or images.

[0011] As described above, the movable outer shell structure of the projection robot has an overall spherical shape, the sliding window has a spherical arc surface, and the sliding cover is a spherical arc shape that matches the shape of the sliding window.

[0012] As described above, the movable outer shell structure of the projection robot has a light-transmitting projection cover plate on the projection window.

[0013] As described above, the movable shell structure of the projection robot is provided with a distance sensor on the front side of the projection bracket for sensing distance. A sensing window for the distance sensor is opened on the sliding cover plate, and a light-transmitting sensing cover plate is provided on the sensing window.

[0014] As described above, the movable outer shell structure of the projection robot has an opening area on the side wall of the shell, and several through holes are provided in the opening area. A cooling fan and a speaker are provided inside the shell and are attached to the opening area.

[0015] As described above, the movable outer shell structure of the projection robot has a mounting groove on the inner side wall of the shell for accommodating a cooling fan. When the cooling fan is located in the mounting groove, the cooling fan is close to the opening area.

[0016] As described above, the movable outer shell structure of the projection robot has an opening area that is a ring-shaped band surrounding the shell.

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

[0018] 1. Achieving a dynamic sealing and integrated design enhances both the product's protective performance and aesthetics. This structure features a sliding cover that rotates synchronously with the projection bracket and is concentrically positioned with the arc-shaped sliding window at the front of the casing. This ensures that the sliding cover remains flush against the window edge during projection angle adjustments, achieving a dynamic sealing effect. This design not only effectively prevents dust and foreign objects from entering the interior, protecting critical components (such as the projection device and sensors), but also avoids the casing gaps caused by angle adjustments in traditional projection equipment, significantly improving the product's structural sealing and lifespan. Furthermore, the sliding cover's shape matches the window, resulting in a spherical or arc-shaped appearance that enhances the product's design aesthetics and technological feel, achieving a unity of function and aesthetics.

[0019] 2. The integrated multi-functional modules and compact structural layout enhance product intelligence and space utilization. Within a limited space, this structure achieves a high degree of integration of multiple functional modules, including projection, display, sensing, heat dissipation, and audio output. The rear-mounted display component enables information prompts and human-computer interaction; the sensing window and light-transmitting cover ensure the proper functioning of the distance sensor; and the shared annular opening area for the cooling fan and speaker not only saves space but also improves the overall compactness and functionality. Furthermore, the rational layout and modular structure of the functional components facilitate assembly and maintenance, making it suitable for various applications such as smart homes, education, and commercial displays, and possessing excellent scalability and promising prospects for intelligent applications.

[0026] The utility model will be further described below with reference to the accompanying drawings:

[0027] 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.

[0028] This embodiment describes a movable shell structure for a projection robot, such as... Figures 1 to 4 As shown, the system includes a robot 1, which comprises a housing 11. Inside the housing 11 is a projection bracket 12 capable of rotating around a pivot P. The projection bracket 12 is equipped with a projection device 13 for projecting an image forward. A drive device 14 is located between the housing 11 and the projection bracket 12 to drive the projection bracket 12 to rotate, allowing the projection device 13 to adjust its angle vertically to suit different projection needs. The projection device 13 is an optical device that projects images or videos onto a screen, wall, or other flat surface using a light source and optical system. For details, refer to the patent application CN201820273153.7 entitled "Projector and Projection Device". The drive device 14 can be a small motor, such as a micro DC motor or a stepper motor, to achieve precise control of the projection angle. The front of the housing 11 has an arc-shaped sliding window 100, and the projection bracket 12 is connected to an arc-shaped sliding cover 15 that can cover the sliding window 100. The centers of the sliding cover plate 15 and the sliding window 100 are both located on the rotation axis P, allowing the sliding cover plate 15 to slide against the edge of the sliding window 100 when the projection bracket 12 rotates. The sliding cover plate 15 has a projection window 151 for the projection device 13 to emit light. Through this structure, the sliding cover plate 15 rotates along with the projection bracket 12, and the centers of the sliding cover plate 15 and the sliding window 100 correspond to the rotation axis P, allowing the sliding cover plate 15 to slide along the sliding window 100. The sliding cover plate 15 and the sliding window 100 have the same center, which coincides with the rotation axis (rotation axis P) of the projection bracket 12. Therefore, when the projection bracket 12 rotates around the rotation axis P, the sliding cover plate 15, as its extension, also moves with the same center, achieving a gapless sliding contact between the cover plate and the window. This design ensures that the sliding cover 15 always completely covers the sliding window 100 during changes in projection angle, thus maintaining the airtightness of the casing and preventing dust and foreign objects from entering, while also improving the overall appearance of the product. The cover always slides in close contact with the window, avoiding seal failure due to angle changes. It eliminates the need for additional slide rails or complex transmission mechanisms, resulting in a simple and reliable structure. The matching design between the cover and the window enhances the product's aesthetics.

[0029] Furthermore, when the sliding cover 15 rotates upward until the projection window 151 moves to the upper end of the sliding window 100, the lower end of the sliding cover 15 still covers the sliding window 100; when the sliding cover 15 rotates downward until the projection window 151 moves to the lower end of the sliding window 100, the upper end of the sliding cover 15 still covers the sliding window 100. The sliding cover 15 can always cover the sliding window 100, keeping the product relatively sealed, protecting internal components, and enhancing the overall integrity of the product's appearance.

[0030] To be more specific, such as Figures 1 to 4 As shown, the housing 11 is composed of a bottom shell 111 and an upper shell 112. The bottom shell 111 is provided with a lower recess 113, and the upper shell 112 is provided with an upper recess 114. The lower recess 113 and the upper recess 114 are connected to form the sliding window 100. The bottom shell 111 and the upper shell 112 are combined to form a cavity for installing functional components.

[0031] To make the sliding cover 15 slide more smoothly, such as Figure 5 and Figure 6 As shown, the inner side of the bottom shell 111 is provided with a first limiting plate 115 located on both sides of the sliding cover plate 15, and the inner side of the upper shell 112 is provided with a second limiting plate 116 located on both sides of the sliding cover plate 15. The first limiting plate 115 and the second limiting plate 116 are arranged on both sides of the sliding cover plate 15 to guide and improve the sealing performance. The design of the limiting plates provides precise guidance for the movement of the sliding cover plate 15, so that it maintains a stable trajectory when rotating around the pivot P, avoiding deviation or jamming. At the same time, the gap design between the limiting plates can accommodate the edge of the sliding cover plate 15, which plays an auxiliary sealing role and prevents dust from entering from the side. The limiting plates provide guidance to ensure the stability of the sliding cover plate's movement trajectory, reduce side gaps through the limiting structure to improve dustproof performance, and the modular design facilitates assembly and maintenance.

[0032] As a preferred option, such as Figures 1 to 3 As shown, the bottom shell 111 has a lower arc-shaped notch 117, and the upper shell 112 has an upper arc-shaped notch 118. A display component 16 is provided between the bottom shell 111 and the upper shell 112, covering the lower arc-shaped notch 117 and the upper arc-shaped notch 118. The display component 16, the bottom shell 111, and the upper shell 112 together form a spherical shell. The display component 16 is provided with a display device 161 capable of displaying lights or images, wherein the display device 161 can be an LED light capable of displaying lights or a display screen capable of displaying images. The front of the robot 1 is used for projection, and the rear of the robot 1 can display some prompt lights or images through the display device 161 to enhance the interactivity with the user.

[0033] Meanwhile, the casing 11 is spherical in shape, the sliding window 100 is shaped like a spherical arc, and the sliding cover 15 is also spherical, matching the shape of the sliding window 100, making the entire product casing appear spherical. This spherical structure not only has excellent visual appeal but also facilitates 360-degree projection and display functions. The rear display component adopts an arc-shaped notch design, consistent with the overall spherical outline, ensuring a compact structure and unified appearance. The spherical appearance has a strong modern feel, conforming to the aesthetic trends of smart home products. The rear display component can realize functions such as information prompts and facial feedback, enhancing the user experience. The matching shapes of each component improve the overall assembly precision and aesthetics.

[0034] As a preferred option, such as Figures 1 to 4 As shown, the projection window 151 is covered with a light-transmitting projection cover 152 to prevent the lamp head of the projection device 13 from being exposed, thereby improving the stability and overall appearance of the product. The lamp head and sensor are protected, preventing direct exposure. The cover and the outer shell are the same color and material, enhancing the overall look and improving protection without affecting the projection and ranging functions.

[0035] Similarly, such as Figures 1 to 4 As shown, the projection bracket 12 is also equipped with a distance sensor 17 for sensing distance on its front side. The sliding cover 15 has a sensing window 153 for exposing the distance sensor 17, and the sensing window 153 is covered with a light-transmitting sensing cover 154. The design of the light-transmitting cover not only meets the normal working requirements of the optical sensor and the projection device, but also effectively prevents external dust and foreign objects from entering, while maintaining the consistency of the product's appearance.

[0036] As a preferred option, such as Figures 1 to 4 As shown, the side wall of the housing 11 is provided with an opening area 101. In order to improve the overall integrity of the product, the opening area 101 is an annular strip surrounding the housing 11.

[0037] The opening area 101 is provided with a plurality of through holes 102, and the housing 11 is provided with a cooling fan 103 and a speaker 104 disposed in close proximity to the opening area 101.

[0038] The cooling fan 103 and the speaker 104 share the same through hole 102 in the same opening area 101, which not only enhances the compactness of the product, but also improves the overall aesthetics of the appearance.

[0039] To allow the cooling fan 103 to be installed inside the opening area 101, the inner wall of the housing 11 is provided with a mounting groove 105 for accommodating the cooling fan 103. When the cooling fan 103 is located in the mounting groove 105, it is in close contact with the opening area 101. The design of the annular opening area 101 balances heat dissipation and audio output functions, reduces structural redundancy through a unified layout, and maintains a simple product appearance. The cooling fan 103 is installed in the mounting groove 105, ensuring a tight fit with the opening area and improving heat dissipation efficiency. The shared through-hole area reduces the number of openings, improves product compactness, ensures a reasonable fan installation position and clear airflow path, and the surrounding design of the opening area enhances the overall visual appeal while meeting the needs of heat dissipation and audio output, resulting in structural optimization.

[0040] 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.
