Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent furniture, and particularly relates to a multi-modal environment adaptive intelligent photo frame. BACKGROUND

[0002] In homes, offices and commercial spaces, people generally hope to display multiple photos to record life, create a specific atmosphere or carry out brand promotion. However, the traditional static photo frame has natural limitations in display capacity and dynamic effect, and cannot meet the growing demand for dynamic, personalized and intelligent display experience.

[0003] The traditional multi-photo photo frame switches photos by manually flipping or rotating a mechanical structure (such as a leaf type or a rotating wheel type) containing multiple photos. It completely relies on manual operation of the user and cannot achieve automatic cycle display, resulting in poor experience. Limited by the physical structure, the number of photos that can be accommodated is usually very limited (usually several to dozens of photos). The digital electronic photo frame uses a liquid crystal display screen, stores digital photos through a storage chip, and displays them in the form of a slide show. It lacks physical entity: the display effect is essentially a combination of pixels, and cannot restore the texture, luster and stereoscopic effect of real photos, and has weak emotional carrying capacity.

[0004] Therefore, it is necessary to provide a multi-modal environment adaptive intelligent photo frame to solve the problems in the background art. SUMMARY

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a multi-modal environment adaptive intelligent photo frame, comprising a shell, the front of the shell is a transparent display window, both sides of the shell inside are provided with a connecting belt, a plurality of pairs of clamping assemblies are evenly distributed and connected in each connecting belt;

[0006] A pair of lower pulley sets are arranged at the bottom of each side shell, an upper pulley set is arranged at a certain distance above the lower pulley set, and a top pulley is arranged above the display window;

[0007] A square storage box is arranged in the shell at the height position between the lower pulley sets and the upper pulley sets between the two connecting belts, a side door is opened on the side surface of the shell and communicates with the storage box, a plurality of display sheets are placed in the storage box, and photos are attached to both sides of the display sheets.

[0008] Further, the shell is further provided with a light module, an environment sensing module and a controller;

[0009] The environment sensing module is used for collecting environment parameters and sending them to the controller;

[0010] The controller drives the connecting belt driving mechanism, and controls the operation of the driving mechanism according to the environmental parameters, so as to adaptively switch the display sheet.

[0011] Further, a multi-modal interaction module is arranged on the shell.

[0012] The multi-modal interaction module comprises at least two of a voice recognition unit, a touch sensing unit and a wireless communication unit; the multi-modal interaction module is in signal connection with a controller, and the controller is configured to control the connecting belt to perform corresponding operations, including switching the display sheet, pausing the display or positioning to a specific display sheet, according to instructions from different interaction units.

[0013] Further, the clamping assembly comprises two fixed blocks symmetrically fixed on two sides of the connecting belt, a clamping rod is hingedly arranged in each fixed block, a clamping block made of rubber is fixed at the end of the clamping rod, and a spring is arranged between the two clamping rods.

[0014] Further, a guide rod is fixed on the side of each clamping rod away from the connecting belt.

[0015] Further, the connecting belt is provided with guide plates fixed on the inner wall of the shell at the upper and lower positions of the connecting belt between the lower pulley set and the upper pulley set, the guide plates are arc-shaped plates protruding towards the side wall of the shell, and the positions of the back surfaces of the two ends of the guide plates are tangent to the positions of the corresponding guide rods.

[0016] Further, an outlet capable of allowing the display sheet to move out is arranged at the bottom of the storage box in the direction close to the display window, and a roller strip is rotatably arranged below the outlet.

[0017] Further, outwardly inclined inclined plates are fixed on the upper four walls of the storage box.

[0018] Further, a rubber baffle is fixed above the outlet in the storage box.

[0019] Further, one or more pulleys in the lower pulley set, the upper pulley set and the top pulley are connected to a servo motor, and the roller strip is connected to the servo motor.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] In the present application, the design of the storage box, the core of the device, enables a single photo frame to have the capacity of an album, capable of accommodating dozens or even hundreds of photos, and continuously displaying the photos through an automatic circulation system, solving the pain points of limited display quantity and the need for manual replacement of the traditional photo frame. The display sheet with double-sided photo display enables the display sheet to be flipped after each circulation, directly doubling the effective display content under the condition that the physical space remains basically unchanged.

[0022] In the present application, the clamping assembly uses a spring to provide a constant clamping force, ensuring that the display sheet does not accidentally fall off during transportation and display, and its reliability is much higher than that of the electromagnetic clamping scheme which relies on electricity. Through the cooperation of the fixed arc-shaped guide plate and the guide rod, precise and automatic clamping and releasing actions are realized at the upper and lower positions of the storage box. The entire "picking-display-returning" process is driven by a single motor, and there is no need to equip each clamp with an independent drive source. The system structure is simple, the failure rate is low, the operation is stable, and the noise is small. By placing the used display sheet back on the top of the storage box, a circular queue is naturally formed, ensuring that all photos can be displayed in an orderly manner.

DETAILED DESCRIPTION

[0030] Please refer to Figures 1-6 In the embodiment of the present application, a multi-modal environment adaptive intelligent photo frame includes an outer shell 1, the front of the outer shell 1 is a transparent display window 2, both sides of the outer shell 1 are provided with a connecting belt 4, and a plurality of pairs of clamping assemblies 5 are evenly distributed in each connecting belt 4.

[0031] A pair of lower belt wheel sets 41 are arranged at the bottom of each side of the outer shell 1, an upper belt wheel set 42 is arranged at a certain distance above the lower belt wheel set 41, and a top belt wheel 43 is arranged above the display window 2.

[0032] A square storage box 6 is arranged in the shell 1 between the height position of the lower pulley set 41 and the upper pulley set 42 between the two connecting belts 4, a side door 3 is arranged on the side of the shell 1 to communicate with the storage box 6, and a plurality of display sheets 8 are placed in the storage box 6, and photos are attached to both sides of the display sheets 8.

[0033] The clamping assemblies 5 distributed in the two connecting belts 4 sequentially clamp both sides of the display sheets 8 from the storage box 6, so that the display sheets 8 move with the connecting belts 4.

[0034] The connecting belts 4 between the lower pulley set 41 and the top pulley 43 are parallel to the display window 2, so that the photos on the display sheets 8 can be displayed outward when the display sheets 8 move to this section, the connecting belts 4 between a pair of lower pulley sets 41 are horizontally arranged at the bottom of the storage box 6, and the clamping assemblies 5 clamp the display sheets 8 in the storage box 6, and the connecting belts 4 between a pair of upper pulley sets 42 are horizontally arranged at the upper part of the storage box 6, and the clamping assemblies 5 at this position release the display sheets 8 in the connecting belts 4 back into the storage box 6, so that the photos in the storage box 6 are sequentially displayed on both sides.

[0035] The device integrates all photos in a photo frame unit, the storage box 6 can compactly stack a large number of display sheets, so that a single photo frame has an album-level capacity, and is suitable for places with limited space but want to display a large number of photos.

[0036] In the embodiment, the shell 1 is also provided with a light module, an environment sensing module and a controller.

[0037] The environment sensing module is used for collecting environment parameters and sending them to the controller.

[0038] The controller drives the driving mechanism of the connecting belts 4, and is used for controlling the operation of the driving mechanism according to the environment parameters, so as to adaptively switch the display sheets 8.

[0039] Through the environment sensing module (which can be a light sensor, a human body infrared sensor, a clock module, etc.), the photo frame can perceive the change of the surrounding environment and intelligently respond.

[0040] Application scenarios are as follows:

[0041] Light self-adaptation: The environment light sensor detects that the environment becomes dark (night), and the controller can instruct the driving mechanism to pause switching photos, or dim the backlight of the display window, so as to save energy and avoid light pollution.

[0042] User presence detection: The human body sensor detects that the user has left for a period of time, and the controller can instruct to pause the cycle, and the user returns to restore, so as to realize energy saving and privacy protection.

[0043] Time adaptation: According to the internal clock, automatically switch to the photos of a specific theme (such as family photos) at a specific time (such as morning), realize the scene display.

[0044] In this embodiment, a multi-modal interaction module is also arranged on the shell 1.

[0045] The multi-modal interaction module includes at least two of voice recognition unit, touch sensing unit and wireless communication unit; the multi-modal interaction module is signal connected with a controller, and the controller is configured to control the connecting belt 4 to perform corresponding operations according to the instructions from different interaction units, including switching the display piece, pausing the display or positioning to a specific display piece.

[0046] By integrating at least two different interaction modes (such as voice, touch, mobile phone APP remote control), the user can interact with the photo frame in the way he is most used to. The user can say "next photo", and after the voice recognition unit receives the instruction, the controller commands the drive mechanism to switch to the next display piece. Touching a specific area can achieve switching or pausing. Through the wireless communication unit, the user can select a specific photo from the gallery of the storage box on the mobile phone APP, and the controller will command the transmission system to quickly position and display the photo.

[0047] In this embodiment, the clamping assembly 5 includes two fixed blocks 51 symmetrically fixed on both sides of the connecting belt 4, a clamping rod 52 is hinged in each fixed block 51, a rubber clamping block 53 is fixed at the end of the clamping rod 52, and a spring 54 is arranged between the two clamping rods 52.

[0048] Under the action of the spring 54, the two clamping rods 52 will approach each other, and the two clamping blocks 53 will clamp the side edges of the display piece 8.

[0049] In this embodiment, a guide rod 55 is fixed on one side of each clamping rod 52 away from the connecting belt 4.

[0050] By turning the guide rod 55, the two clamping rods 52 can overcome the elastic force of the spring 54 and move away from each other to loosen the clamping block 53 and release the side edges of the display piece 8.

[0051] In this embodiment, the connecting belt 4 between the lower pulley set 41 and the upper pulley set 42 is provided with a guide plate 7 fixed on the inner wall of the shell 1, the guide plate 7 is an arc-shaped plate protruding towards the side wall of the shell 1, and the positions of the back surfaces of the two ends of the guide plate 7 are tangent to the positions of the corresponding guide rods 55.

[0052] When the clamping assembly 5 in the connecting belt 4 moves to the position of the guide plate 7, the guide rod 55 will be attached to the back of the guide plate 7, and as the clamping assembly 5 moves to the middle of the guide plate 7, the guide plate 7 guides the guide rod 55 to move close to the side wall of the housing 1, at this time, the two clamping rods 52 corresponding to the clamping assembly 5 overcome the elastic force of the spring 54 and move away from each other to make the clamping block 53 loose the side edge of the display sheet 8;

[0053] That is, the clamping assembly 5 will be opened when passing above and below the storage box 6, so that the clamping assembly 5 passing above the storage box 6 is loose and the display sheet 8, and the clamping assembly 5 passing below the storage box 6 is opened and ready to clamp the new display sheet 8.

[0054] The guide plate 7 is designed as a center-protruding arc-shaped plate, and is tangent to the guide rod 55, and the smooth transition makes the opening action gradual and soft, reduces the impact, noise and wear of the parts, makes the whole operation process more stable, and the whole "clamping-transporting-releasing" process can be realized by driving the connecting belt 4 by one motor, without needing to equip each clamping assembly 5 with an independent driver or electromagnet, greatly simplifying the circuit design and control system, and significantly reducing the manufacturing cost and complexity.

[0055] In the embodiment, the bottom of the storage box 6 is provided with an outlet 61 capable of moving the display sheet 8 out, and the roller 62 is rotatably arranged below the outlet 61.

[0056] The display sheet 8 located at the lowermost part of the storage box 6 will be taken out of the outlet 61 by the rotation of the roller 62, and the display sheet 8 moved out of the outlet 61 will be clamped by the clamping block 53 of the clamping assembly 5 away from the guide plate 7, and as the display sheet 8 gradually leaves the storage box 6, it will be clamped by multiple clamping assemblies 5 and moved to the display window 2 for display.

[0057] In the embodiment, the upper four walls of the storage box 6 are fixed with outwardly inclined inclined plates 63.

[0058] The inclined plates 63 make the upper part of the storage box 6 funnel-shaped, ensuring that the display sheet 8 can smoothly and accurately fall into the storage box 6.

[0059] In the embodiment, the rubber baffle 64 is fixed above the outlet 61 in the storage box 6.

[0060] The friction force of the baffle 64 on the display sheet 8 is less than the friction force of the roller 62 on the display sheet 8 and greater than the friction force between the upper and lower display sheets 8, ensuring that the display sheet 8 located at the lowermost part can be taken out of the storage box 6 by the roller 62, and the upper display sheet 8 is blocked in the storage box 6 by the baffle 64.

[0061] In this embodiment, one or more of the pulleys in the lower pulley set 41, the upper pulley set 42 and the top pulley 43 are connected to servo motors, and the roller strip 62 is connected to a servo motor.

[0062] By controlling the operation of the servo motors, the connecting belt 4 and the roller strip 62 can be synchronized to work, ensuring that the display sheet 8 is continuously clamped by the clamping assembly 5.

[0063] In particular implementation, the working process of the intelligent photo frame is an efficient circulation system integrating orderly automatic control and intelligent human-computer interaction.

[0064] A large number of display sheets with photos pasted on both sides are vertically stacked in the storage box. At the bottom of the storage box, a set of roller strips driven by servo motors rotate slowly. The display sheet at the bottom is driven by the friction of the roller strips and tries to move towards the outlet. At this time, the friction of the soft rubber stopper above the outlet on the display sheet is just greater than the friction between the two adjacent display sheets, but less than the friction of the roller strips on the bottom display sheet, so that the bottom display sheet can be smoothly pushed out, and the display sheets above are effectively blocked by the stopper, ensuring that only one display sheet is taken out each time, avoiding multiple display sheets sticking together. When the front end of the display sheet slowly moves out of the outlet, a pair of passing clamping assemblies directly below are driven by the connecting belt and just leave the control area of the guide plate. Under the action of the spring, the two clamping rods quickly close inward, and the rubber clamping blocks at the ends accurately and firmly clamp the two side edges of the display sheet. Subsequently, the subsequent clamping assemblies clamp the display sheet in turn, so that it smoothly leaves the storage box and starts to rise.

[0065] The reliably clamped display sheet moves upwards along the parallel path with the connecting belt, enters the stage of vertically crossing the display window after passing through the lower pulley set, and in the display window area, the connecting belt is parallel to the glass, and the display sheet can be clearly front-facing to the audience. During this period, the light sensor in the environment perception module will monitor the ambient brightness, and the controller will automatically adjust the light module in the display window accordingly to ensure that the photo can obtain the best display effect under any light.

[0066] After the display sheet reaches the top pulley with the connecting belt, it turns and starts to move downward, and then enters the area above the storage box. When the clamping assembly runs to the guide plate near the upper pulley set, the guide rod contacts the arc-shaped guide plate. As the connecting belt continues to move, the guide rod slides along the arc-shaped back of the guide plate and is gradually pushed outward, so that the clamping rod overcomes the spring force and opens outward, and the rubber clamping block releases the display sheet. The released display sheet naturally falls under the action of gravity. Since the top of the storage box is provided with an outwardly inclined "funnel type" inclined plate, the display sheet is guided and smoothly slides to the top of the photo stack in the storage box, ensuring that the photo displayed later always falls on the photo displayed earlier, thereby realizing the circulation queue of all photos and ensuring that each photo has a chance to be displayed.

[0067] The above merely provides the preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
