It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

With the adoption of the household and multi-purpose projectors, users often change the physical positions and angles of hardware of the projection equipment, and the inventor finds that the behaviors are highly correlated with the startup and shutdown behaviors of the users, but the existing projection equipment still needs the users to independently execute the operation of controlling the startup and shutdown of the projectors, so that the startup and shutdown processes of the users are complicated, the operation is inconvenient, and the time and the energy of the users are wasted.

Based on this, an aspect of the embodiments of the present application provides a projection apparatus, as shown in fig. 1, including: the projection device comprises a mounting assembly 100, a projection device main body 200, a detection assembly 300 and a control module 400, wherein the projection device main body 200 is mounted on a base body 500 through the mounting assembly 100. The detection assembly 300 is used to detect pose information of the projection apparatus main body 200. The control module 400 determines whether the projection apparatus main body 200 satisfies the start-up timing according to the pose information, and controls the projection apparatus main body 200 to start up to project a projection onto a projection surface when it is determined that the projection apparatus main body 200 satisfies the start-up timing.

The base 500 is an object that can be used for installation work, and may be, for example, a headboard, a wall 900, a desk, or the like. The mounting assembly 100 is a device capable of mounting the projection apparatus main body 200 on the base 500, and may be, for example, the mounting assembly 100 that can be clamped on a headboard, or a magnetic adsorption base that can be adsorbed on a magnetic object, and the mounting assembly 100 having a different shape structure may be selected according to the actual needs of a user.

The pose information is information that can represent the relative positional relationship between the components of the projection apparatus, the relative positional relationship between the projection apparatus and the surrounding environment, or the positional change information of the projection apparatus main body 200 with respect to a reference, and the like, i.e., the pose information is information that can represent the projection apparatus intended by the user to turn on or off the projection apparatus. For example, the pose information may include angle information such as position information of the projection apparatus main body 200 and a projection angle of the projection apparatus main body 200, but is not limited thereto, and may include acceleration data reflecting a current movement pose of the projection apparatus main body 200, and the like. The pose information may be coordinate information of an object around the projection apparatus main body 200 in a coordinate system constructed with a point on the projection apparatus main body 200 as an origin, and coordinate information of the installation component 100 or other components in the projection apparatus in the coordinate system, and the pose information may be direct distance values, etc., and data that can reflect the pose of the projection apparatus main body 200 is within the scope of the present application.

The control module 400 may be a single component, an integrated circuit integrating various chips and devices, or a functional component with information processing capability integrated with the projection apparatus itself, and the specific form of the control module 400 is determined according to specific products, as long as the components capable of implementing the above method steps are all forms of the control module 400 claimed in this application. The starting time refers to the time when the current pose information is enough to represent that the user needs to start the projection equipment. It is understood that the pictures referred to in this application may be images or video, etc. The projection surface may be a projection screen, a wall surface on which a projection picture can be displayed, a floor, a ceiling or other projectable plane, and so on.

According to the application, when a user needs to use the projection device to project a picture, the projection effect is optimized by adjusting the position, the lens angle and the like of the projection device, so that the current position, angle and other posture information of the projection device is closely related to the intention of the user to start or shut down the projection device, based on this, the projection device provided by the embodiment of the application installs the projection device main body 200 on the base 500 through the installation component 100, the base 500 can be a headboard, a desk and the like, the posture information of the projection device main body 200 is detected through the detection component 300 and is transmitted to the control module 400, the control module 400 can judge whether the user currently has the intention of using the projection device to project according to the posture information, that is, judge whether the current projection device main body 200 meets the start opportunity, if the start opportunity is judged to be met, the projection device main body 200 is controlled to be started to emit projection to the projection surface, and in the whole process, a user does not need to execute additional starting operation through a starting button or a remote controller on the projection device, so that the method is fast and convenient, the preparation time of the user before projection is shortened, and the user experience is improved.

For the mode of automatically turning on and turning off the projector lens cap by detecting the on-off state of the projector lens cap in the traditional technology, the process of turning on and off the projector lens cap is similar to the process of using a key switch, and the user needs to operate a specific component of the projection equipment to turn on and off the projector lens cap, that is, when the user adjusts or changes the physical position and angle of the hardware of the projection equipment to adjust the projection direction, the operation needs to be executed additionally to turn on and turn off the projector lens cap, which is not simple, convenient and intelligent enough.

In one embodiment, as shown in fig. 2, the detecting assembly 300 includes a position sensor 310, and the position sensor 310 is used for detecting distance data between the projection apparatus main body 200 and an object around the base 500 and uploading the distance data to the control module 400; when determining that the distance data falls within the target distance set, the control module 400 determines that the projection apparatus main body 200 meets the start-up timing, and controls the projection apparatus main body 200 to start up.

The position sensor 310 may be a proximity sensor, an infrared sensor, or other devices capable of detecting a distance to another object, and the specific type may be selected according to an actual application scenario. The object around the base 500 is an object that can be detected in the detection range of the position sensor 310 in the current installation environment.

The target distance set is a range formed by a set of distance data of the projection apparatus main body 200 and objects around the base 500 in the state acquired when the user starts to use the projection apparatus. Taking the case that the projection device is installed on the headboard through the installation component 100 as an example, the headboard is arranged close to the wall 900, when the user needs to see the image, the projection device is required to be pulled out from the position close to the wall so that the projection direction is projected to the wall 900 opposite to the bed, and the projection direction is further adjusted to be projected to the ceiling by adjusting the position of the projection device main body 200 relative to the installation component 100 after being pulled out, in both cases, the projection device is required to be pulled out from the position of the wall 900 close to the headboard first, in this case, the target distance set can be determined by collecting the distance data between the projection device main body 200 and the wall 900 (the wall 900 is the wall 900 close to the headboard) when the user normally uses the projector to see the image in the earlier stage, and determining a set by using the data sample (in the process of determining the set, abnormality can be screened first), the distance data falling within the set can be used as a condition for determining that the user has a power-on demand (i.e., meets the power-on opportunity).

When a user needs to use the projection equipment, the posture of the projection equipment is adjusted to adjust the projection direction of the projection equipment to the position which is customary in daily viewing, in the process, the position sensor 310 continuously detects the distance data between the projection equipment main body 200 and the objects around the base body 500 and uploads the distance data to the control module 400, once the control module 400 judges that the distance data falls into the target distance set, the intention of the user to use the projection equipment when starting is indicated, namely the starting time is met currently, the control module 400 immediately controls the projection equipment main body 200 to start, the whole process does not need the user to execute independent starting operation, the user can be automatically started according to the behavior habit of the user, the use is convenient, and the user experience is good.

In one embodiment, the control module 400 is further configured to determine whether the projection apparatus main body 200 meets the closing timing according to the pose information, and is configured to control the projection apparatus main body 200 to shut down when it is determined that the projection apparatus main body 200 meets the closing timing.

The closing time refers to the time when the current pose information is enough to represent that the user needs to shut down the projection equipment. For example, when the projection apparatus main body 200 is installed on a headboard through the installation assembly 100, a user does not need to use a projector after finishing watching an image, in order to avoid that the projector is in a pulled-out state for a long time, that is, located above a pillow, and affecting the user's activities in such a state, at this time, the projection apparatus main body 200 needs to be retracted towards the wall 900 close to the headboard, so that the projection apparatus main body 200 is as close to the wall as possible, in this scene, the pose information of the projection apparatus main body 200 after the user is powered off and the projection apparatus main body 200 is retracted can be used as a reference value, in the subsequent use process, once the control module 400 matches the pose information uploaded by the detection assembly 300 with the pose information that the projection apparatus main body 200 is usually located after the power off, it is indicated that the current user has an intention to power off, and at this time, it can be determined that the projection apparatus main body 200 meets the power off timing, the control module 400 controls the projection apparatus main body 200 to power off, and the power on/off operation is performed without a user through a remote controller, and the intention of the user to power on/off is determined by combining the pose of the projection apparatus main body 200 and the behavior habit of the user, so that the automatic control of the power on/off is realized. The shutdown control scheme in this embodiment and the startup control scheme in the above embodiments may be used simultaneously or separately, that is, the embodiments in this application may be combined reasonably.

In one embodiment, the control module 400 is configured to determine that the projection apparatus main body 200 meets the shutdown timing and control the projection apparatus main body 200 to shut down when the distance data is determined to be outside the target distance set.

Similarly, since the distance data may be used as a data basis for determining the power-on, or as a data basis for determining the power-off timing, or as an example of the scenario that the projection apparatus main body 200 is installed on the headboard as mentioned in the above example, when the user finishes watching the image, the user wants to push the projection apparatus main body 200 to a position close to the wall 900 so as to avoid colliding with the user, and in the process of pushing the projection apparatus main body 200 to rotate toward the wall 900, the position of the projection apparatus main body 200 relative to the wall 900 (the object around the base 500) is changed until the distance between the two is small enough to depart from the target distance set, which indicates that the user has the intention to power off, and then the control module 400 controls the projection apparatus main body 200 to power off.

In one embodiment, the detection assembly 300 includes an inertial sensor 320, the inertial sensor 320 is used for detecting acceleration data of the projection apparatus main body 200; the control module 400 receives the acceleration data, determines that the projection apparatus main body 200 meets the closing timing when it is detected that the acceleration data is greater than a preset acceleration threshold, and controls the projection apparatus main body 200 to shut down.

Inertial sensors 320 refer to devices capable of detecting and measuring acceleration, tilt, shock, vibration, rotation, and multiple degree of freedom (DoF) motion parameters. The acceleration threshold is a minimum acceleration value sufficient for judging that the user rapidly moves the projection device due to the fact that the application scene needs to be changed, and therefore, when the acceleration threshold is larger than the acceleration threshold, namely, the application scene needs to be changed currently by the user, the projection device needs to be reset. At this moment, when monitoring that the acceleration data is greater than the preset acceleration threshold, the controller controls the theme of the projection equipment to shut down, on one hand, energy consumption can be saved, on the other hand, the situation that the projection equipment is collided in the moving process to cause short circuit of an electronic circuit or a device in the projection equipment to burn out the whole projection equipment is also prevented, and at this moment, the danger can be further prevented through active shutdown control.

In one embodiment, as shown in fig. 3-11, the mounting assembly 100 includes: the clamping structure 110, the support 120 and the rotating mechanism 130, wherein the clamping structure 110 is matched with the base body 500 in shape and is used for being clamped and installed on the base body 500; one end of the support 120 is connected to the clamping structure 110; one end of the rotating mechanism 130 is connected to the support 120, and the other end of the rotating mechanism 130 is used to connect to the projection apparatus main body 200.

The holding structure 110 is used for carrying and mounting, and is used for holding a substrate 500 such as a bed head, and is connected to the projection apparatus main body 200 through the support 120 and the rotating mechanism 130. It is understood that the substrate 500 may be a bed head, a table top, a bookcase arm, a tree trunk, or a portion of an object; correspondingly, the projection surface mentioned above may be a wall surface, a floor surface, a ceiling surface, or a projection surface formed by a surface of a component.
