Description

Technical Field

[0001] This utility model relates to the field of seal technology, and in particular to a manual-automatic cloud-based intelligent seal device. Background Technology

[0002] In recent years, a new type of Internet of Things (IoT) product—the cloud-based smart seal terminal—has emerged and gained widespread use. By configuring a high-performance CPU, multiple (three or more) cameras, a 4G module, a security module, a fingerprint sensor, and a position sensor, it can monitor the use of built-in physical seals. Through cooperation with a smart seal management platform (cloud platform server + management terminal (PC or mobile), it can achieve functions such as seal application, approval, pre-seal document comparison, authorized unlocking, seal use evidence snapshot, automatic generation of seal use records (user, time, location, frequency, etc.), intelligent seal use auditing, real-time monitoring and recording of seal use, and uploading encrypted videos to the management platform for storage and decryption for retrieval.

[0003] This cloud-based intelligent seal, based on the Internet of Things (IoT), revolutionizes the traditional human-managed seal control model, providing a high-security, networked, digital, and intelligent management solution for the entire seal usage process. Due to its high security, efficiency, and intelligence, it has been widely welcomed by the market. However, because of its important position and role in the market, coupled with its widespread use, potential seal usage control risks have also emerged, which may cause certain economic losses to users. The main potential risks are as follows:

[0004] Potential Risk: When a user is authorized to use the smart stamp, the method of manually pressing down on the stamp handle can lead to a situation where, after pressing the handle to the paper and completing the stamping, if the user continues to press the handle and then quickly moves the stamp to another sheet of paper to stamp or make a rubbing, more than one stamp mark may be generated within a single stamping press window. Because the dwell time of the smart stamp on the paper after authorization is difficult to predict precisely, there is a subjective element of manual control, leading to the risk of unauthorized stamping or rubbing. Although the smart stamp can be set with a time limit and an alarm for exceeding the time limit, the lower limit is limited (subject to various detection and processing time constraints), so there is still a risk of being stamped more than twice. Therefore, this still poses a certain risk to the user.

[0005] To avoid the potential occurrence of multiple stamp marks within a single stamping time window, this patent provides a technical solution to manage this potential risk: a manual / automatic cloud-based intelligent stamp device. Utility Model Content

[0006] The purpose of this utility model is to provide a manual-automatic cloud-based intelligent stamp device, which solves the problem of malicious behavior that may occur when manually stamping with a cloud-based intelligent stamp, namely, the undesirable consequence of producing more than two stamp marks with a single manual press.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] A manual / automatic cloud-based intelligent stamp device includes a control system and a stamp motion control assembly. The stamp motion control assembly includes a drive mechanism, a stamp handle, a stamp outer sleeve, a stamp inner sleeve disposed within the stamp outer sleeve, a stamp clamp, a conversion device, and a compression spring sleeved on the outer wall of the stamp inner sleeve. The lower end of the compression spring is fixed to the central partition of the stamp outer sleeve, and the upper end of the compression spring is fixed to the upper end of the stamp inner sleeve via a compression spring stop. The stamp handle passes through sliding grooves on both sides of the stamp outer sleeve and is connected to two fixed ears of the compression spring stop. The control system is used to control the stamping.

[0009] Preferably, a motor fixing device is provided inside the inner sleeve of the seal. The motor fixing device includes a motor fixing plate, and the motor fixing plate has a through hole for the output shaft of the motor to pass through.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this utility model is to provide a manual-automatic cloud-based intelligent stamp device, which solves the problem of malicious behavior that may occur when manually stamping with a cloud-based intelligent stamp, namely, the undesirable consequence of producing more than two stamp marks with a single manual press.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figures 1 to 2 A manual / automatic cloud-based intelligent stamp device includes a control system, a stamp handle, a stamp outer sleeve, a central partition with a central hole inside the stamp outer sleeve, a stamp inner sleeve above the central partition, a physical stamp clamp located below a motor fixing plate in the stamp inner sleeve, a motor located inside the stamp inner sleeve, a conversion device located at the motor output end, and a compression spring sleeved on the outer wall of the stamp inner sleeve. The lower end of the compression spring is fixed to the central partition, and the upper end of the compression spring is fixed to the upper end of the stamp inner sleeve via a compression spring stop. The stamp handle passes through sliding grooves on both sides of the stamp outer sleeve and is connected to two fixed ears of the compression spring stop. The control system is used to control the stamping. This invention solves the problem of potential malicious behavior when manually stamping with a cloud-based intelligent stamp, namely, the undesirable consequence of producing more than one stamped mark with a single manual press.

[0029] refer to Figures 1 to 2 The inner sleeve of the seal is provided with a motor fixing device, which includes a motor fixing plate and a through hole for the output shaft of the motor to pass through.

[0030] refer to Figure 1 The driving mechanism includes a motor and a conversion device disposed at the output end of the motor. The conversion device is connected to the physical stamp holder, and the motor is used to drive the movement of the physical stamp holder.

[0031] refer to Figures 6 to 7 The conversion device includes a mounting sleeve for connecting to the output end of the motor and two sets of impellers arranged vertically and with opposite arc surfaces around the mounting sleeve. The surfaces of the two sets of impellers are arc surfaces, and the two sets of impellers are used to hang or push the hooks of the physical stamp holder.

[0032] refer to Figure 2 The control system includes a CPU circuit board, a DC motor driver chip, a manual travel detection switch, and a power supply. The CPU circuit board is located in the circuit board slot opened in the outer sleeve of the seal, and the DC motor driver chip is connected to the motor wire.

[0033] Furthermore, it also includes a battery power supply and fast charging module, a safety module, a 4G module, a video acquisition module, a display module, and a storage module.

[0034] A method for using a manual / automatic cloud-based intelligent stamp device includes the following steps:

[0035] 1) Press the power button on the cloud smart seal terminal and wait for the cloud smart seal to power on;

[0036] 2) Obtaining the Seal Authorization Code (After the seal application document is approved, the management platform will issue a seal authorization code to the user's APP or PC client software). This manual / automatic cloud-based intelligent seal obtains the seal authorization code by using a built-in video or fingerprint collection device to collect the user's face or fingerprint. This data is encrypted and stored locally, and then uploaded to the server for comparison with registered data. If the comparison matches, the seal authorization code is issued to the user, authorizing them to use the seal. Simultaneously, the electronic certificate containing the user's collected data is encrypted, timestamped, and uploaded to the server to ensure the user's identity is verified.

[0037] 3) The user enters the obtained authorization code into the authorization interface of the cloud smart seal to open the smart lock of the cloud smart seal.

[0038] 4) After hearing the voice prompt that the smart seal has been successfully unlocked, the user should quickly place the smart seal on the paper to be stamped and press down on the seal handle. The seal handle will compress the spring and drive the seal motion control assembly to move towards the paper, completing the manual downward stroke H1 (see...). Figure 6 (As shown).

[0039] 5) After the manual downward stroke H1 is completed, continue pressing the handle of the cloud smart seal in place for about 2 to 4 seconds. During this period, the cloud smart seal CPU motherboard program will read the position sensor detection data to see if the manual stroke H1 is completed. Once the manual stroke is detected to be completed, i.e., switch K1 is closed, the program will immediately call the vision module and OCR recognition module to analyze and determine whether the conditions for using the seal are met.

[0040] If the conditions are met (i.e., no fraudulent visual behavior, and the OCR comparison of the stamped document and the application document matches), the automatic security step H2 is executed. Specifically, the DC motor is output with forward rotation data, driving it to rotate forward. When the DC motor rotates forward, the rotational motion is converted into vertical motion via a conversion device, causing the physical stamp holder to push downwards inside the stamp sleeve. The physical stamp holder then presses the stamp onto the document to be stamped. Figure 7 As shown, Figure 7A schematic diagram of the automatic security stroke H2 section of the cloud-based smart seal is provided. Simultaneously, the cloud-based smart seal's CPU motherboard program collects the document data via a document acquisition camera, timestamps and encrypts it before uploading it to the server to ensure the "real text" authentication of the document. After stamping, the motor immediately starts to reverse to the maximum reverse position, stopping the stamping process and achieving seal security protection. Simultaneously, the cloud-based smart seal's CPU motherboard program collects the stamp imprint data via a stamp imprint acquisition camera, timestamps and encrypts it before uploading it to the server to ensure the "real seal" authentication of the stamp imprint. After one stamping cycle, this cloud-based smart seal has achieved the authentication, encryption, and uploading of "real person, real document, real seal" three-real electronic credentials to the cloud server. The "three-real" electronic credential data uploaded to the cloud server can be further uploaded to a blockchain server for blockchain storage, ensuring the "three-real" electronic credential data cannot be tampered with.

[0041] If there is a discrepancy (i.e., either there is visual evidence of fraud or the OCR comparison between the stamped document and the application document is inconsistent), the stamping will be deemed invalid, and the user will be instructed to release the manual press of the stamp handle. After release, the stamp handle, the physical stamp holder, and the physical stamp will automatically return to their initial positions under the action of the spring. (Note: Visual evidence of fraud includes, but is not limited to, malicious stamping behaviors such as obstructing the stamping data acquisition camera, removing or inserting stamping paper, or transferring stamping paper.)

[0042] Furthermore, for practical stamping scenarios, the following implementation methods and steps can be derived from the use of a manual / automatic cloud-based intelligent stamp device:

[0043] 1) Example 1 of the control method for a single stamp application with N stamp imprints

[0044] The method of using the seal is as follows: N seal impressions are generated by N*H1 travel + N*H2 automatic safety travel. After unlocking with the seal authorization code, each seal impression requires one H1 travel + one H2 travel; N seal impressions are formed by N*(one H1 + one H2).

[0045] 2) Example 2 of a method for controlling the use of N imprint scenarios with a single stamp application.

[0046] The method of using the seal is as follows: the generation of N seal impressions consists of 1*H1 travel + N*H2 automatic security travel. After unlocking with the seal authorization code, manually pressing the H1 travel once will trigger the corresponding N*H2 automatic security travel at each of the N seal positions.

[0047] 3) Example 3 of a method for controlling the use of N imprint scenarios with a single stamp application.

[0048] The method of using this stamp is as follows: N stamps are generated by an automatic safety stroke consisting of (N+X)*H1 stroke + X*H2 stroke (1≤X≤M, M can be greater than N, X is the number of fraudulent acts). Specifically for mode 3, during the generation of N stamps, the H2 stroke is performed first, followed by the N*H1 stroke. If a fraudulent act is detected, an H2 reversal is performed, and an H1 reversal is also required. If X fraudulent acts occur during the N stamp generation, an X*H2 compression / retraction operation and a (N+X)*press operation are required.

[0049] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
