Description

Technical Field

[0001] This disclosure relates to a display case. Background Technology

[0002] Display cases are used to display various items, such as beverages and food. To better manage the goods displayed in the display cases, most products on the market currently use camera modules with gyroscopes installed on the doors of the display cases. The angle for the camera to capture images is selected by setting the tilt variable of the gyroscope when the door is opened. However, due to different opening forces, the instantaneous tilt of the gyroscope is also different, resulting in different angles when capturing photos. Furthermore, if the display case door is not closed for a long time after it has been opened, or if the door rotates back and forth slightly, the gyroscope will not be able to find the best angle for the camera to capture images, and thus the camera will not be able to capture the display of goods inside the case when the door is closed.

[0048] like Figures 1 to 5 As shown, this disclosure provides a display cabinet 100. In some embodiments, the display cabinet 100 includes:

[0049] The cabinet has an interior space for storing the displayed items and has an opening.

[0050] Cabinet door 1 is configured as a closed opening, and cabinet door 1 is rotatably connected to the cabinet body via mounting shaft 2;

[0051] The triggering mechanism 3 is connected to the end of the mounting shaft 2 near the outside of the cabinet door 1, and the triggering mechanism 3 rotates together with the cabinet door 1;

[0052] Position switch 4, fixedly installed in the cabinet, is configured to be triggered when trigger mechanism 3 rotates to a preset angle; and

[0053] The camera component 5 is located on the side wall of the cabinet door 1 facing the storage space and is signal-connected to the position switch 4. The camera component 5 is configured to photograph the placement of items inside the cabinet when the position switch 4 is in the triggered state.

[0054] The cabinet contains items for display or sale, including beverages, food, and other items. It has an opening, which can be located at the front. A cabinet door 1 is rotatably connected to the cabinet via a mounting shaft 2, for example, mounted on the edge of the left or right side wall. One or two doors 1 can be installed, forming a double door. A handle can be installed on the outer wall of the door 1 near the open end. A camera component 5 is installed on the inner wall of the door 1, for example, near the handle. The camera component 5 can be a camera or similar device used to capture images or videos of the items within the storage space.

[0055] Both the trigger mechanism 3 and the position switch 4 are located on the outside of the cabinet door 1. The trigger mechanism 3 rotates together with the cabinet door 1, and the rotation center of the trigger mechanism 3 is aligned with the central axis of the mounting shaft. For example, both the trigger mechanism 3 and the position switch 4 can be located in the area below or above the cabinet door 1. During the rotation of the cabinet door 1, when the cabinet door 1 rotates to a preset angle suitable for shooting, the trigger mechanism 3 applies external force to the position switch 4, thereby triggering the position switch 4. The position switch 4 then sends a signal to the shooting component 5 to initiate the shooting.

[0056] This embodiment, by setting up a mechanical mechanism, can accurately determine the optimal shooting angle for the shooting component 5 inside the cabinet, so as to capture the image at the optimal shooting angle position. It can monitor the items inside the cabinet. The structure is simple, has a lower cost and higher reliability compared with gyroscopes, and allows users to grasp the display situation inside the display cabinet more quickly and accurately.

[0057] In some embodiments, the triggering mechanism 3 includes:

[0058] Connecting part 33 is connected to mounting shaft 2;

[0059] The guide portion 31 is connected to the outside of the connecting portion 33, and the outer wall of the guide portion 31 has an arc-shaped guide surface;

[0060] The trigger part 32 is connected to the guide surface, and the trigger part 32 protrudes relative to the guide surface;

[0061] The position switch 4 includes an external force receiving part. The position switch 4 is configured to be in a triggered state when the external force receiving part is located on the triggering part 32, and in a non-triggered state when the external force receiving part is located in a region of the guide surface other than the triggering part 32.

[0062] For example, the connecting part 33 can be a cylindrical structure and can be coaxially connected to the bottom of the mounting shaft 2. The guide part 31 is radially connected to the outside of the connecting part 33, and the radially outer side wall of the guide part 31 has an arc-shaped guide surface.

[0063] In this embodiment, the triggering mechanism 3 allows the external force receiving part of the position switch 4 to move along the guide surface (excluding the triggering part 32) when the cabinet door 1 is not at a suitable preset shooting angle. The guide surface guides the movement of the external force receiving part, preventing it from being subjected to pressure. When the cabinet door 1 is at a suitable preset shooting angle, the external force receiving part of the position switch 4 reaches the position of the triggering part 32. Because the triggering part 32 protrudes outward, the external force receiving part is triggered by pressure, thereby transmitting the trigger signal to the shooting component 5 for shooting. This structure can accurately, reliably, and effectively obtain the optimal shooting position.

[0064] In some embodiments, the guide surface is arc-shaped.

[0065] Since cabinet door 1 rotates along an arc-shaped trajectory, and the triggering mechanism 3 is on the same axis of rotation as cabinet door 1, the guide surface is designed to be arc-shaped. This ensures that when cabinet door 1 rotates to a non-optimal shooting angle, the external force receiving part of position switch 4 is not subjected to force, preventing accidental triggering in areas outside the optimal shooting angle, thereby ensuring a suitable shooting angle.

[0066] In some embodiments, the guide portion 31 has a fan-shaped structure, and the trigger portion 32 is located in the middle region of the guide surface in the circumferential direction.

[0067] This embodiment takes into account that the rotation angle of the cabinet door 1 is generally less than 180°. The guide part 31 is designed as a fan-shaped structure, and the fan angle is not less than the maximum rotation angle of the cabinet door 1, which can meet the usage requirements and reduce the space occupied by the triggering mechanism 3. Moreover, when the cabinet door 1 is opened to about half of its maximum angle, the cabinet door 1 is tilted relative to the plane where the opening is located, which is more conducive to the shooting component 5 to take pictures from all directions, so as to accurately obtain the image of the displayed items.

[0068] In some embodiments, the sidewall of the trigger portion 32 is arc-shaped, and the sidewall of the trigger portion 32 is connected to the guide surface by an arc-shaped transition.

[0069] This embodiment enables the external force receiving part of the position switch 4 to smoothly switch positions between the trigger part 32 and the guide surface when the cabinet door 1 reaches a preset angle suitable for shooting and when it leaves the preset angle suitable for shooting, preventing jamming and unreliable triggering of the shooting component 5 to perform actions, and improving the service life of the position switch 4.

[0070] In some embodiments, the position switch 4 includes a micro switch, the micro switch includes a body part 41, the external force receiving part includes a spring 42 and a roller 43, the first end of the spring 42 is connected to the body part 41, the second end of the spring 42 is provided with the roller 43, and the roller 43 contacts the guide surface or the trigger part 32.

[0071] For example, the first end of the spring 42 is connected to the body part 41, the body part 41 is provided with an elastic element on the side facing the spring 42, and the body part 41 is provided with a pin 44.

[0072] like Figure 2 As shown, when the roller 43 slides on the guide surface on one side, no pressure is applied to the spring 42. Under the action of the elastic element, the spring 42 makes the roller 43 contact the guide surface, the micro switch is in a free state, and the internal circuit is in an open state.

[0073] like Figure 3 As shown, when the roller 43 moves from the guide surface to the trigger part 32, the cabinet door 1 just reaches the preset angle suitable for shooting. The trigger part 32 presses the roller 43 to drive the spring 42 closer to the body part 41. During this process, the spring 42 overcomes the force of the elastic element and approaches the body part 41. At this time, the micro switch is activated, and the two pins 44 change from the disconnected state to the connected state.

[0074] like Figure 4 As shown, when the cabinet door 1 continues to rotate, and the roller 43 moves from the trigger part 32 to the guide surface on the other side, the elastic element returns to its initial form, forcing the spring piece 42 away from the body part 41, so that the roller 43 re-contacts the guide surface, the micro switch returns to the free state, and the internal circuit is in the disconnected state.

[0075] In this embodiment, the position switch 4 is easy to cooperate with the triggering mechanism 3, and the triggering of the position switch 4 is reliably and sensitively realized, thereby enabling shooting at a suitable preset angle.

[0076] In some embodiments, such as Figure 1 As shown, the mounting shaft 2 is set vertically, the trigger mechanism 3 is located at the bottom of the cabinet door 1, and there is a gap between the trigger mechanism 3 and the bottom of the cabinet door 1. The position switch 4 is located on the side of the trigger mechanism 3 away from the opening of the cabinet door 1. This arrangement makes it easy to install the position switch 4 and provides enough space for disassembly and maintenance.

[0077] In some embodiments, when the triggering mechanism 3 rotates to a preset angle, the cabinet door 1 is in a partially open state during the opening or closing process, and the shooting component 5 is tilted relative to the plane where the opening is located to take pictures.

[0078] This embodiment can accurately take a picture every time cabinet door 1 is opened and every time cabinet door 1 is closed. Since the arrangement of items inside the display cabinet does not change until the door is closed next time, the pictures obtained before cabinet door 1 is closed can more accurately reflect the arrangement of items.

[0079] In some embodiments, the display case further includes a locking element, wherein the circumferential position of the triggering mechanism 3 relative to the mounting shaft 2 is adjustable, and the locking element is configured to lock the position of the triggering mechanism 3 relative to the mounting shaft 2. For example, the locking element may be a locking screw or a locking member, etc.

[0080] This embodiment allows for easy adjustment of the circumferential position of the trigger mechanism 3 relative to the mounting shaft 2, so as to obtain the best preset angle for shooting through position adjustment. Alternatively, for different areas where items are placed inside the cabinet, the installation angle of the trigger mechanism 3 can be adjusted to focus on and clearly shoot the areas where items are placed. After adjustment, the position can be locked by the locking mechanism.

[0081] In some embodiments, such as Figure 5 As shown, the display case also includes:

[0082] Industrial control computer 6, connected to the imaging component 5 via signal, is configured to receive image information transmitted by the imaging component 5 during the opening or closing of cabinet door 1; and

[0083] Remote server 7 is connected to industrial control computer 6 via a signal and is configured to receive image information sent by industrial control computer 6.

[0084] For example, position switch 4 is connected to the imaging component 5 via a wire. When the external force receiving part of position switch 4 is in a free state, its internal circuit is disconnected and it will not send an imaging signal to the imaging component 5. When the external force receiving part of position switch 4 is under pressure, its internal circuit is connected, and it sends an imaging signal to the imaging component 5. At this time, the opening angle of cabinet door 1 is just right so that the imaging component 5 can completely capture the complete display inside the cabinet. The captured image is transmitted through industrial control computer 6 and then uploaded to remote server 7 via network for backend viewing. Industrial control computer 6 can be installed inside the display cabinet.

[0085] This embodiment, by setting up an industrial control computer 6 and a remote server 7, can upload images captured by the imaging component 5 in real time for real-time viewing or saving, making it convenient for operators to understand the items inside the display case from a distance.

[0086] Each time cabinet door 1 is opened or closed, it will take an image at the optimal preset angle and upload it to the remote server 7. The changes in the items can be judged by comparing the images obtained during the opening or closing of cabinet door 1.

[0087] While this disclosure has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this disclosure. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This disclosure is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
