The main body has a card slot for installing a memory card. The card cover is connected to the main body in a closed manner, covering the card slot when the card cover is closed. The main body also has a photosensitive hole located within the area covered by the card cover. The main board has a photosensitive circuit configured such that there is no current when the photosensitive hole is blocked, and there is current when the photosensitive hole is not blocked.

Description

Technical Field

[0001] This application relates to the field of security monitoring technology, and in particular to card cover installation detection devices and imaging equipment. Background Technology

[0002] In the field of security monitoring, IPCs (Internet Protocol Cameras) are the core devices for video acquisition and transmission. Their stability and data security directly affect the overall performance of the monitoring system, and the market demand for their functional completeness and reliability continues to rise. With the increasing demand for local storage, it has become a common practice to install SD cards (Secure Digital Cards) during the installation and commissioning phase of IPC network cameras, according to specific customer needs. The design of SD cards and related protection structures has become a key aspect in ensuring the stable outdoor operation of the equipment.

[0003] To address the potential damage or theft of SD cards during outdoor use due to an improperly installed SD card cover, and the data loss that may result from directly opening the SD card cover and removing the SD card while the device is running, the industry has developed corresponding technical solutions. The current mainstream approach involves adding specific structural components that use clips to press and engage with the inner wall of the device to secure the SD card cover. A tumbler lock spring-triggered detection mechanism is then employed to relay the lock status of the card cover to the motherboard, thereby monitoring the SD card cover's installation status and protecting the data read / write process.

[0004] However, existing technical solutions have significant limitations in practical applications. On the one hand, the addition of numerous structural components to achieve the aforementioned functions results in a substantial difference from the original structure of the equipment. This not only increases the complexity of the structural design but may also adversely affect the overall layout and space utilization of the equipment. On the other hand, the SD card cover is connected to the entire machine via a hinge, which requires high precision machining and specialized hinge components, significantly increasing the manufacturing cost of the equipment. Furthermore, the insufficient compatibility of the newly added structural components with the original structure may lead to loosening of the fit due to vibration, environmental corrosion, and other factors during long-term use, affecting detection accuracy and protection effectiveness, and further reducing the reliability of the equipment. Utility Model Content

[0005] Therefore, it is necessary to provide a card cover installation detection device and a shooting device to address the problems of high cost and poor reliability in monitoring the card cover installation status of SD cards in shooting equipment.

[0006] A card cover installation detection device includes a main body, a card cover, and a main board. The main body has a card slot for installing a memory card. The card cover is connected to the main body in a cover-like manner, and when the card cover is closed on the main body, it can cover the card slot. The main body also has a photosensitive hole located in the area covered by the card cover. The main board has a photosensitive circuit, which is configured such that there is no current when the photosensitive hole is blocked, and there is current when the photosensitive hole is not blocked.

[0007] In one embodiment, the photosensitive circuit includes a photosensitive element located at the photosensitive aperture with the photosensitive surface of the photosensitive element facing the photosensitive aperture, and the photosensitive element is configured to generate a current when it receives light.

[0008] In one embodiment, the photosensitive hole is formed on the end face of the body perpendicular to the closing direction of the card cover, and the photosensitive hole is located within the projection of the card cover in the closing direction of the card cover.

[0009] In one embodiment, the card cover installation detection device includes a signal processing unit configured to monitor whether there is current in the photosensitive circuit and output an alarm signal when there is current in the photosensitive circuit.

[0010] In one embodiment, the card cover installation detection device includes a response module, which is communicatively connected to the signal processing unit and configured to trigger when an alarm signal is received from the signal processing unit.

[0011] In one embodiment, the response module is configured to emit an alarm sound and / or light.

[0012] In one embodiment, the response module is configured to generate a visual pop-up.

[0013] In one embodiment, the response module is configured to send alarm messages to the associated remote management platform.

[0014] In one embodiment, the response module is configured to trigger the saving of data within the memory card.

[0015] A shooting device includes a card cover installation detection device as described in any of the above embodiments.

[0016] The card cover installation detection device provided in the above solution sets a photosensitive hole in the coverage area of ​​the card cover and configures a photosensitive circuit that is affected by whether the photosensitive hole is blocked. By detecting whether there is current in the photosensitive circuit, it can determine whether the card cover is blocking the photosensitive hole, and thus infer whether the card cover is closed to the main body. Its structure is simple, with few changes compared to the original structure, and is compatible with most of the original structural components. Only one photosensitive hole needs to be added at the card slot of the machine body, thereby reducing costs. At the same time, the use of a photosensitive circuit to realize the card cover closure detection is low in cost, highly sensitive, and not affected by the service life, thus having high reliability.

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0027] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0028] One embodiment of this application provides a shooting device, which may be a camera, but is not limited thereto. The shooting device includes a card cover installation detection device as described in any of the following embodiments. The card cover installation detection device is used to detect whether the card cover is closed, to avoid problems such as damage or theft of the memory card during outdoor use due to the card cover not being installed, and to avoid data loss problems that may be caused by directly opening the memory card cover and removing the memory card during device operation.

[0029] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the structure of a card cover in a card cover installation detection device according to an embodiment of this application. The card cover installation detection device provided in this embodiment can be applied to the aforementioned imaging equipment, but is not intended to limit its application. The card cover installation detection device includes a main body 100, a card cover, and a main board. Figure 1 As shown, the main body 100 has a card slot 110 for installing a memory card.

[0030] In some implementations, such as Figure 1 As shown, the main body 100 also has fastening holes 130 for mounting the main body 100 to other components of the shooting device. For example... Figure 1 As shown, the main body 100 also has a reset button 140 for resetting the shooting equipment.

[0031] The card cover is connected to the main body 100 in a closed manner, and when the card cover is closed on the main body 100, it can cover the card slot 110 to prevent the memory card from being damaged or stolen when used outdoors. Figure 1 As shown, the main body 100 also has a photosensitive hole 120 located within the area covered by the card cover. It can be understood that the photosensitive hole 120 can be inside the card slot 110 or located on the outer periphery of the card slot 110. However, since the photosensitive hole 120 is located within the area covered by the card cover, when the card cover is closed to the main body 100, the card cover blocks the photosensitive hole 120. The motherboard has... Figure 2 The photosensitive circuit 200 shown is configured such that there is no current when the photosensitive hole 120 is blocked, and there is current when the photosensitive hole 120 is not blocked. The presence or absence of current in the photosensitive circuit 200 determines whether the card cover is blocking the photosensitive hole 120, and further infers whether the card cover is closed on the main body 100. It is understood that in other embodiments, the current may be smaller when the photosensitive hole 120 is blocked, below a set current value, and larger when the photosensitive hole 120 is not blocked, not lower than the set current value. The set current value is obtained based on monitoring when the card cover is closed on the main body 100, and is applicable when the card cover cannot completely block the photosensitive hole 120 when closed on the main body 100.

[0032] Combination Figure 2 As shown, in one embodiment, the photosensitive circuit 200 includes a photosensitive element located at the photosensitive aperture 120, with the photosensitive surface of the photosensitive element facing the photosensitive aperture 120. The photosensitive element is configured to generate a current when it receives light, and converts the received light signal into an electrical signal, realizing the mutual conversion between light and electrical signals. In other embodiments, the photosensitive circuit 200 can also be configured in other ways. For example, the photosensitive element can also be a photoresistor, whose resistance decreases when exposed to light. In this case, the change in current of the photosensitive circuit 200 can be used to infer whether the card cover is blocking the photosensitive aperture 120, and thus whether the card cover is closed on the main body 100.

[0033] Combination Figure 1 As shown, in one embodiment, the photosensitive hole 120 is opened on the end face of the main body 100 perpendicular to the closing direction of the card cover, and the photosensitive hole 120 is located within the projection of the card cover in the closing direction of the card cover, so that when the card cover is closed on the main body 100, the card cover completely blocks the photosensitive hole 120, and the photosensitive element in the photosensitive circuit 200 cannot receive light, or receives very little light, and a current is generated in the middle of the photosensitive circuit 200.

[0034] In one embodiment, the card cover installation detection device includes a signal processing unit configured to monitor whether there is current in the photosensitive circuit 200 and output an alarm signal when there is current in the photosensitive circuit 200. Based on the current in the photosensitive circuit 200, the device infers that the card cover is not closed or is not fully closed to the body 100, thereby issuing an alarm signal.

[0035] In one embodiment, the card cover installation detection device includes a response module, which is communicatively connected to the signal processing unit and configured to trigger upon receiving an alarm signal from the signal processing unit to alert the user when the card cover is not closed or not fully closed to the body 100.

[0036] In one embodiment, the response module is configured to emit an alarm sound and / or light to alert the user that the card cover is at risk of not being closed.

[0037] In one embodiment, the response module is configured to generate a visual pop-up, for example, a visual pop-up that can appear on the screen of the shooting device to remind the user that there is a risk that the card cover is not closed.

[0038] In one embodiment, the response module is configured to send alarm messages to the associated remote management platform. For example, it encapsulates the alarm signal into an HTTP (Hypertext Transfer Protocol) / MQTT (Message Queuing Telemetry Transport) protocol message through a built-in network module (such as WiFi / Ethernet), and transmits the message to a cloud server or local management platform. The alarm message then pops up in the management interface accessed through a browser or a mobile APP (application).

[0039] In one embodiment, the response module is configured to trigger the saving of data in the memory card, thereby eliminating the risk of data loss caused by removing the card while the device is running.

[0040] Combination Figure 3As shown, the imaging device with a card cover installation detection device, after installation and power-on, will detect whether the card cover is open by checking for current in the photosensitive circuit 200. If there is current in the photosensitive circuit 200, the card cover is open, the signal processing unit will issue an alarm signal, the response module will respond to the alarm, and data will be stored. If there is no current in the photosensitive circuit 200, the card cover is closed.

[0041] The card cover installation detection device provided in the above solution sets a photosensitive hole 120 in the coverage area of ​​the card cover and configures a photosensitive circuit 200 that is affected by whether the photosensitive hole 120 is blocked. By detecting whether there is current in the photosensitive circuit 200, it can determine whether the card cover is blocking the photosensitive hole 120, and then infer whether the card cover is closed to the main body 100. Its structure is simple, with few changes compared to the original structure, and is compatible with most of the original structural components. Only one photosensitive hole 120 needs to be added at the card slot 110 of the body, thereby reducing costs. At the same time, the use of the photosensitive circuit 200 to realize the card cover closure detection is low in cost, highly sensitive, and not affected by the service life, thus having high reliability.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
