Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a folding companion chair with an Internet of Things (IoT) locking function. Background Technology

[0002] Currently, hospital wards are widely equipped with companion chairs to facilitate caregivers' companionship and nursing of patients. Due to limited ward space and the need for a quiet environment, these chairs are typically folded up during the day and used as companion beds at night. This presents management challenges for medical institutions. Some institutions opt to install padlocks or chain locks, requiring staff to patrol and unlock them at night, and then remind patients to fold up and lock them before morning rounds. This entire process is cumbersome and inconvenient for management and use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a folding companion chair with IoT locking function that is unattended, accepts mobile payment, can be used as a chair after being folded down, has a lock body that is suitable for most current models of companion chairs, and is easy to install and disassemble.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a folding companion chair with IoT locking function, comprising a support frame, a back frame hinged to one end of the support frame, a back panel on the back frame, a backrest frame connected to one end of the back frame via a rotating connector, a backrest panel on the backrest frame, a seat frame hinged to the other end of the backrest frame, a chair leg support below the seat frame, a seat panel on the seat frame, a lock body connected to the lower part of the seat frame via a fixing device, a cord fixing end on the back frame that cooperates with the lock body, the lock body comprising an elastic cord reel, a drive motor, a one-way locking device, a control chip, a power supply device, and a cord guide block, wherein the elastic cord reel contains an elastic steel wire. The lock body includes a rope and coil sensor. The elastic steel wire rope extends to the outside of the lock body and is fixedly connected to the fixed end of the rope. The output end of the drive motor is equipped with a phase block. The other end of the phase block is connected to a push rod. The other end of the push rod is equipped with a spring device. The one-way locking device is fixedly connected to the lock body via a rotating shaft. One end of the one-way locking device is equipped with a tooth that fits against the elastic steel wire rope, and the other end abuts against the phase block. A return spring is provided on the side wall of the one-way locking device near the push rod. The other end of the return spring is connected to a spring fixing block. The spring fixing block is fixedly connected to the lock body. The lock body is equipped with a power supply device, which is electrically connected to the elastic wire reel, the control chip, and the drive motor.

[0005] The one-way locking device has teeth that control the extension and retraction of the elastic steel wire rope. When the drive motor causes the push rod to move to the right via the phase block, the teeth of the one-way locking device are tilted downwards, allowing the elastic steel wire rope to stretch inwards or outwards. Conversely, when the teeth of the one-way locking device are tilted upwards, the elastic steel wire rope can only retract inwards. The control chip includes a control module, a communication module, a motor drive module, and a clock module. The control module is the core control brain of the device, used to receive, process, and output commands to control the normal operation of other modules. The communication module is connected to the control module and is used to receive and transmit command data with the cloud service platform and mobile terminal. The motor drive receives commands from the control module and outputs commands to the drive motor. The clock module triggers the time commands from the control module to control the timed rotation of the drive motor and uploads the phase information of the drive motor, the coil size data of the coil sensor, and the power supply information of the power supply device to the cloud server. The drive motor receives instructions from the control chip and controls the position of the push rod by rotating the phase. The power supply device is connected to the control chip, the drive motor, and the coil sensor. The cord guide block is used to limit the position of the elastic steel wire rope. The fixing device is used to fix the position of the lock body on the companion chair, ensuring that the lock body is not easily removed or moved, thus allowing it to be easily installed on ordinary companion chairs.

[0006] Furthermore, the lock body controls the phase of the drive motor to enable the companion chair to achieve controllable extension and retraction and one-way locking functions. When the lock body is in the locked state, the drive motor phase block moves to the left to accommodate the push rod, thereby causing the return spring to press against the one-way locking device. In this state, the elastic steel wire rope cannot be stretched outward due to the restriction of the wheel teeth, but it can be contracted inward with the contraction force of the spring plate built into the elastic winding device. Thus, the companion chair can only be folded up and cannot be unfolded for use. During the process of folding up to the fully folded backrest position, the companion chair is in a locked state that can be folded up but cannot be unfolded for use in any position. When the lock body is in the unlocked state, the drive motor phase block moves to the right to press against the push rod, thereby causing the top wheel teeth of the one-way locking device to be in a loose state. In this state, the elastic steel wire rope can be stretched freely in both directions, so that the companion chair can be used freely by the caregiver.

[0007] Furthermore, the lock body can accurately determine the folded and extended state of the companion chair through the wire rope coil sensor. When the coil is at a large value, it means that the companion chair is in the folded state; conversely, when the coil is at a small value, it means that the companion chair is in the extended state.

[0008] Furthermore, the lock body will have an external unique identification code to identify its uniqueness, and this code will be stored and recorded in the cloud service platform for the mobile terminal to scan and interact with.

[0009] Furthermore, the lock body can be easily installed on and replaced with different models of companion chairs from various manufacturers, thereby enabling ordinary companion chairs to have the ability for users to scan codes for self-service use and to accurately manage the extension status of the companion chair.

[0010] The cloud service platform includes a device management module, an order management module, a user login module, a scheduled task module, a billing module, a fault maintenance module, a statistical analysis module, and an SMS module. The device management module registers information such as the lock body's device information, location, status, battery level, and wire rope coil size. The order module handles business orders sent from the mobile terminal, processes them according to business logic, and returns the processing result.

[0011] Furthermore, the timed task module can be customized according to the individual needs of medical institutions. At the task time points set by the medical institution, it sends an unlocking command to the lock body based on the usage information pre-registered by the user through the mobile terminal, thereby facilitating care for the elderly.

[0012] Furthermore, the billing module is used to set different billing modes for different devices, which facilitates the self-service operation, charging, and settlement of the companion chair, so that the companion chair equipped with the lock body can adapt to the operational needs of different operating entities and scenarios.

[0013] Furthermore, the fault maintenance module is used to manage and handle various faults that occur in the device and respond to user emergency fault alarms. It is also equipped with an intelligent maintenance terminal for the operating entity, which enables the operating entity to keep track of the status information of the lock body, power information, and the status information of the companion chair in real time, thereby enhancing the intelligent maintenance capabilities of the equipment.

[0014] Furthermore, the SMS module will send timely and accurate reminders to users who have not put away their companion chairs on time, based on the time restrictions set by the medical institution.

[0015] The mobile terminal includes a user login module, a device scanning module, a usage registration module, and a payment settlement module. After the user identifies the unique identification code of the lock body by using the device scanning module, a two-way communication connection is established with the lock body and the cloud service platform.

[0016] Furthermore, the usage registration module allows selection of the start date and number of days of use, enabling the lock to be opened immediately during unrestricted use periods or scheduled for a future time slot. The advantages of this invention compared to existing technologies are: when the lock is engaged, the backrest and seat frame fit snugly together, allowing it to be used as a chair; when the lock is open, it allows the caregiver to lie down and rest, functioning as a bed.

[0017] The present invention has the following beneficial effects: (1) The present invention can control the extension and retraction and one-way locking of the companion chair through the one-way locking device in the lock body, which has the characteristics of high stability and convenient installation, and is suitable for addition to the existing ordinary companion chair.

[0018] (2) By setting up a lock control chip, a companion chair status sensor, a cloud service platform and a mobile terminal, the present invention can know the extension status of the companion chair in real time, thereby achieving the purpose of saving manual management costs in the unattended mode, as well as precise intelligent management and convenient use.

The lock body 1 includes an elastic cord reel 2, a drive motor 6, a one-way locking device 3, a control chip 5, a power supply device 10, and a cord guide block 13. The elastic cord reel 2 contains an elastic steel wire rope 14 and a coil. Sensor 4; the elastic steel wire rope 14 extends to the outside of the lock body 1 and is fixedly connected to the rope fixing end 15; the output end of the drive motor 6 is provided with a phase block 16; the other end of the phase block 16 is connected to a push rod 8; the other end of the push rod 8 is provided with a spring device 9; the one-way locking device 3 is fixedly connected to the lock body 1 through a rotating shaft 27; one end of the one-way locking device 3 is provided with a wheel tooth 26 that fits against the elastic steel wire rope 14; the other end abuts against the phase block 16; a return spring 7 is provided on the side wall of the one-way locking device 3 near the push rod 8; the other end of the return spring 7 is connected to a spring fixing block 12; the spring fixing block 12 is fixedly connected to the lock body 1; a power supply device 10 is provided inside the lock body 1; the power supply device 10 is electrically connected to the elastic winding device 2, the control chip 5, and the drive motor 6 respectively.

[0025] The back frame 17 is mounted on the support frame 24, and the rotating connector 22 is located away from the hinge point between the support frame 24 and the back frame 17. Rollers 28 are provided below the chair leg support 20. The spring device 9 is fixedly connected to the lock body 1.

[0026] In a specific implementation, this invention provides a controllable telescopic and one-way locking device for a companion chair, comprising a lock body 1, a cloud service platform, and a mobile terminal. The lock body 1 includes an elastic reel 2, a one-way locking device 3, a control chip 5, a drive motor 6, a power supply device 10, a cord guide block 13, and a fixing device 11. The elastic reel 2 includes a coil sensor 4, an elastic steel wire rope 14, and a cord fixing end 15. The coil sensor 4 is connected to the control chip 5 and is used to capture data on the size of the coil of the elastic steel wire rope 14 as it contracts. The elastic steel wire rope 14 passes through a guide tube between the one-way locking device 3 and the cord guide block 13. The cord fixing end 15 is used to fix the position of the elastic steel wire rope 14 on the companion chair. The one-way locking device 3 has teeth that control the extension and retraction of the elastic steel wire rope 14. When the drive motor 6 causes the push rod 8 to move to the right through the phase block 16, the teeth of the one-way locking device 3 are in a downward tilted state, so that the elastic steel wire rope 14 can be stretched inward or outward. Conversely, when the teeth of the one-way locking device 3 are in an upward pressing state, the elastic steel wire rope 14 can only retract inward. The control chip 5 includes a control module, a communication module, a motor drive module, and a clock module. The control module is the core control brain of the device, used to receive, process, and output instructions to control the normal operation of other modules. The communication module is connected to the control module and is used to receive and transmit instruction data with the cloud service platform and mobile terminal. The motor drive module receives instructions from the control module and outputs instructions to the drive motor 6. The clock module triggers the time instructions from the control module to control the timed rotation of the drive motor 6 and uploads the phase information of the drive motor 6, the coil size data of the coil sensor 4, and the power information of the power supply device 10 to the cloud server. The drive motor 6 receives instructions from the control chip 5 and controls the position of the push rod 8 by rotating its phase. The power supply device 10 is connected to the control chip 5, the drive motor 6, and the coil sensor 4. The rope guide block 13 is used to limit the position of the elastic steel wire rope 14. The fixing device 11 is used to fix the position of the lock body 1 on the companion chair, ensuring that the lock body 1 is not easily removed or moved, so that it can be easily installed on an ordinary companion chair.

[0027] Furthermore, the lock body 1 controls the phase of the drive motor 6 to enable the companion chair to achieve controllable extension and retraction and one-way locking functions. When the lock body 1 is in the locked state, the phase block 16 of the drive motor 6 accommodates the push rod 8 to the left, thereby causing the return spring 7 to press against the one-way locking device 3. In this state, the elastic steel wire rope 14 cannot be stretched outward due to the restriction of the wheel teeth, but it can be contracted inward with the contraction force of the spring plate built into the elastic reel 2. Thus, the companion chair can only be folded up and cannot be unfolded for use. During the process of folding up to the fully folded backrest position, the companion chair is in a locked state that can be folded up but cannot be unfolded for use in any position. When the lock body is in the unlocked state, the phase block 16 of the drive motor 6 presses against the push rod 8 to the right, thereby causing the top wheel teeth of the one-way locking device 3 to be in a loose state. In this state, the elastic steel wire rope 14 can be stretched freely in both directions, so that the companion chair can be used freely by the caregiver.

[0028] Furthermore, the lock body 1 can accurately determine the folded and extended state of the companion chair through the wire rope coil sensor 4. When the coil is at a large value, it means that the companion chair is in the folded state; conversely, when the coil is at a small value, it means that the companion chair is in the extended state.

[0029] Furthermore, the lock body 1 will have an external unique identification code to identify the uniqueness of the lock body 1, and the code will be stored and recorded in the cloud service platform for the mobile terminal to scan and interact with.

[0030] Furthermore, the lock body 1 can be easily installed on and replaced with different models of companion chairs from various manufacturers, thereby enabling ordinary companion chairs to have the ability for users to scan codes for self-service use and to accurately manage the extension status of the companion chair.

[0031] The cloud service platform includes a device management module, an order management module, a user login module, a scheduled task module, a billing module, a fault maintenance module, a statistical analysis module, and an SMS module. The device management module registers information such as the device information, location, status, battery level, and wire rope coil size of the lock body 1. The order module handles business orders sent by the mobile terminal, processes them according to business logic, and returns the processing result.

[0032] Furthermore, the timed task module can be customized according to the individual needs of medical institutions. At the task time set by the medical institution, it sends an unlocking command to the lock body 1 based on the usage information pre-registered by the user through the mobile terminal, thereby facilitating the care of the elderly.

[0033] Furthermore, the billing module is used to set different billing modes for different devices, which facilitates the self-service operation, charging, and settlement of the companion chair, so that the companion chair equipped with the lock body 1 can adapt to the operational needs of different operating entities and scenarios.

[0034] Furthermore, the fault maintenance module is used to manage and handle various faults that occur in the device and respond to user emergency fault alarms. It is also equipped with an intelligent maintenance terminal for the operating entity, so that the operating entity can keep track of the status information, power information and companion chair status information of the lock body 1 in real time, thereby enhancing the intelligent maintenance capability of the equipment.

[0035] Furthermore, the SMS module will send timely and accurate reminders to users who have not put away their companion chairs on time, based on the time restrictions set by the medical institution.

[0036] The mobile terminal includes a user login module, a device scanning module, a usage registration module, and a payment settlement module. After the user identifies the unique identification code of the lock body 1 by using the device scanning module, a two-way communication connection is established with the lock body 1 and the cloud service platform.

[0037] Furthermore, the usage registration module can select the start date and number of days of use, so that it can be opened immediately during the unrestricted use period of the companion chair, or it can be scheduled to open the lock body 1 at a later time.
