FIG. 1 is an exemplary block diagram of an intelligent wheelchair according to some embodiments of the present application. The smart wheelchair 170 includes a body, a driving wheel, and a guide wheel. The smart wheelchair 170 may include one or a combination of electric, mechanical, wooden, and hybrid wheelchairs. The temperature adjusting apparatus 100 may be installed on a smart wheelchair 170 for adjusting the ambient temperature of the smart wheelchair. The temperature adjusting apparatus 100 is configured to acquire a set temperature, sense the temperature of a portion of the wheelchair in contact with the body of the user in real time, and intelligently adjust the ambient temperature of the wheelchair based on the set temperature and the real-time temperature. In some embodiments, thermoregulation device 100 may include insulation blanket 110, display 120, temperature sensor 130, temperature control device 140, input device 150, and thermoregulation device 160.

The insulating blanket 110 may be used to regulate the ambient temperature for the user's body tissue. The insulating blanket 110 may further include a bracket (not shown) and a flexible material (not shown). The stent may have two states, a collapsed state and/or an expanded state. In the folded state, the support may fold the flexible material and house the support and flexible material at the top, bottom or armrest of the wheelchair. The stand may be automatically folded. For example, when the user needs to leave the wheelchair, a leaving command may be input through the input device 150, and all the racks are automatically folded. The stand may be manually folded. In the deployed state, the stent may be deployed and support a flexible material covering the body tissue of the user (e.g., head, abdomen, legs, and/or hands). The stent may be automatically deployed. For example, when the input device 150 receives a user's hand heating request, the hand support is automatically deployed. The stent may be manually deployed. The flexible material can be covered on the limbs, the trunk and the head of a user for heat preservation and insulation. The flexible material can contain a temperature sensor for sensing the temperature of the part of the wheelchair contacted with the body of the user in real time. The temperature sensor may be a contact sensor or a non-contact sensor. Heating means may be included in the flexible material for increasing the temperature of the portion of the wheelchair in contact with the user's body.

In some embodiments, insulating blanket 110 may further include abdominal insulating blanket 110-8, leg insulating blanket 110-6, head insulating blanket 110-4, and hand insulating blanket 110-2. In the non-use state, the abdomen warming blanket 110-8 may be stored at the backrest in a folded state. In a use state (e.g., a heating or cooling state, a warming state), the abdomen warming blanket 110-8 may be automatically or manually opened to wrap the abdomen of the user. Leg warming blanket 110-6 may include a left leg warming blanket and a right leg warming blanket, and in a non-use state, leg warming blanket 110-6 may be stored at the leg struts in a folded state. In use, the leg warming blanket 110-6 may be automatically or manually opened to wrap the left and/or right leg of the user. In the non-use state, head thermal blanket 110-4 may be stored in a folded state at the back of the wheelchair. In use, head warming blanket 110-4 may be automatically or manually deployed over the user's head to regulate the ambient temperature of the user's head. Hand insulating blanket 110-2 may include a left hand insulating blanket and a right hand insulating blanket, and in a non-use state, hand insulating blanket 110-2 may be stored at the armrest in a folded state. In use, hand insulating blanket 110-2 may be automatically or manually opened to wrap the left and/or right hand of the user.

The display 120 may display real-time temperature sensed by the temperature sensor 130 and prompting information. The display 120 may be coupled to the temperature control device 140 and the temperature sensor 130. In some embodiments, the display 120 may display the location and the corresponding real-time temperature of the location. The display 120 may display the location and the real-time temperature in a dialog box, may inform the user in a voice manner, or may be a combination thereof. In some embodiments, the display 120 may display a prompt for a user (e.g., a wheelchair user, a caregiver, etc.). The display 120 may prompt the user by displaying a dialog box, by prompting a voice or speech, or a combination thereof. The user can select whether to reply to the prompt, and the reply mode can comprise one or a combination of manual input, voice input and the like. For example, when prompting the user whether to stop heating, the user may click "OK" on the display 120, and the user chooses to stop heating; otherwise, the user may click "Cancel" on the display 120, and the user selects to continue heating. In some embodiments, the display 120 may display the location that needs to be heated (e.g., left hand, right leg). In some embodiments, display 120 may send instructions to temperature control device 140. For example, the user may set the temperature of a portion of the wheelchair in contact with the user's body, i.e., a set temperature, via the display 120, which may be sent to the temperature control device 140. The temperature setting instruction of the portion of the wheelchair in contact with the user's body may include setting a temperature and a portion (e.g., a portion of the wheelchair in contact with the user's left hand, a portion of the wheelchair in contact with the user's right leg), and the like.

In some embodiments, temperature control device 140 may control display 120. For example, temperature control device 140 may control display related parameters. The parameters may include display size, display scale, display order, number of displays, and the like. By way of example, the display of all or part of the real-time temperature of various parts of the user may be controlled. For example, hand, head, leg temperatures are displayed simultaneously or only head temperatures are displayed.

In some embodiments, the display 120 may include a voice prompt device. The voice prompt device is used for prompting the temperature control condition of a user. For example, the voice prompting device may prompt the user for the current real-time temperature. The current real-time temperature may include one or a combination of leg real-time temperature, head real-time temperature, abdomen real-time temperature, hip real-time temperature, hand real-time temperature, back real-time temperature, and the like. As another example, the voice prompting device may prompt the user for the presence of an undeployed insulation blanket and ask if the insulation blanket needs to be deployed. For another example, the voice prompt device may prompt the user whether to stop heating or cooling when the real-time temperature is significantly above or significantly below the optimal temperature for the human body (e.g., the difference between the real-time temperature and the optimal temperature for the human body is greater than 3 ℃).

In some embodiments, the voice prompting device may be independent of the display 120. For example, a voice prompt may be coupled to temperature control device 140. The voice prompt may receive a voice prompt signal from the temperature control device 140. The voice prompt signal includes a temperature control condition.

The temperature sensor 130 is used to sense the real-time temperature of the portion of the wheelchair in contact with the user's body. Temperature sensor 130 transmits the sensed real-time temperature to display 120 and/or temperature control device 140. The temperature sensor 130 may be a contact temperature sensor disposed on a surface of the wheelchair (e.g., at the back of the chair, at the seat cushion). Temperature sensor 130 may be a non-contact temperature sensor located in abdomen thermal blanket 110-8, leg thermal blanket 110-6, head thermal blanket 110-4, and hand thermal blanket 110-2. In some embodiments, the non-contact temperature sensor may be located in the flexible material on a side of the flexible material proximate to the user.

The temperature control device 140 is used for maintaining the body temperature of the user near the set temperature by heating or cooling the part of the wheelchair, which is in contact with the body of the user, based on the real-time temperature and the set temperature. The temperature control device 140 may receive the real-time temperature sensed by the temperature sensor 130. The temperature control device 140 may receive a set temperature received by the input device 150 and/or the display 120. The temperature control device 140 may control the temperature adjustment device 160 to heat or cool based on the real-time temperature and the set temperature. In some embodiments, the temperature control device 140 determines a temperature difference between the real-time temperature and the set temperature, and determines whether to heat or cool based on the temperature difference. For example, when the real-time temperature is higher than the set temperature by more than the first set value, the temperature control device 140 performs cooling by controlling the temperature adjustment device 160 until the difference is equal to or less than the first set value. The first set value may be set by the temperature adjustment device 100 or may be adjusted according to actual conditions. The first set value may be 2 ℃, 3 ℃, 5 ℃, etc. For another example, when the difference between the real-time temperature and the set temperature is greater than the second set value, the temperature control device 140 performs heating by controlling the temperature adjustment device 160 until the difference is equal to or less than the second set value. The second set value may be set by the temperature adjustment device 100 or may be adjusted according to actual conditions. The second set value may be 2 ℃, 3 ℃, 5 ℃, etc. The second set point may be the same as or different from the first set point. Specific embodiments of temperature control device 140 can be found in the description elsewhere in this application.

The input device 150 may be used to receive user input. The input device 150 may be present independently, and may include, for example, a keyboard, a mouse, a microphone, and the like, or any combination thereof. The input device 150 may also be implemented by the display 120 with a touch screen. The user input can comprise one or a combination of a plurality of temperature setting, leaving instruction, prompt message reply, support unfolding instruction, user basic information, weather information and the like. For example, the input device 150 may be used to receive a set temperature input by a user. The set temperature may include a set temperature value and a portion (e.g., left leg) to which the temperature value corresponds. For another example, the input device 150 may be used to receive a leave instruction input by a user. The instruction indicates that the user needs to leave the wheelchair. According to the instructions, the thermoregulation device 100 can automatically fold the holder of the insulation blanket.

The temperature adjusting device 160 is used for heating or cooling the part of the wheelchair in contact with the body of the user based on the instruction of the temperature control device 140. The temperature conditioning device 160 may include gas flow pores. Wherein, the airflow micropores can be made of porous materials, mesh materials or reticular foam materials. The airflow micropores can lead out cold and hot airflow, thereby realizing the adjustment of the temperature of the part of the wheelchair, which is in contact with the body of a user. In some embodiments, thermostat 160 may further include a heating device (not shown) and a cooling device (not shown). The heating device may be used to increase the ambient temperature of the part of the wheelchair that is in contact with the user's body. The heating device may be arranged in a flexible material. The cooling device can be used for reducing the ambient temperature of the part of the wheelchair, which is in contact with the body of a user. The cooling device may be located on the back of the wheelchair on the side not in contact with the back of the user.

In some embodiments, the temperature regulation device 100 may include a communication module (not labeled in the figures). The temperature adjustment device 100 may be connected to a network through a communication module. The network may include wired connections or wireless connections. In some embodiments, the network may be a single network or a combination of networks. For example, the network may include one or a combination of local area networks, wide area networks, public networks, private networks, wireless local area networks, virtual networks, metropolitan area networks, public switched telephone networks, and the like. The network may include a variety of network access points, such as wired or wireless access points, base stations, or network switching points. The components in the temperature adjustment device 100 can be connected to the network through the above access points, so as to realize information interaction. For example, the temperature adjustment device 100 may be connected to a public medical system via the network to obtain historical medical information of the user or to synchronize medical data of the user. For another example, the temperature adjustment device 100 may be connected to a weather website via the network to obtain weather information of the user's location.

In some embodiments, the thermostat 100 may be interconnected and communicate with an external server, database, or terminal device through the network. The server or database may be used for information storage and retrieval. The server can be one or a combination of a plurality of file servers, database servers, FTP servers, application program servers, proxy servers, mail servers and the like. In some embodiments, the server may be a cloud server. The database can be one or a combination of a hierarchical database, a network database, a relational database and the like. The terminal device may receive information output by the temperature adjustment device 100, including a set temperature, a real-time temperature, or other information requested to be viewed by a user. In some embodiments, the terminal device may include one or a combination of a laptop, a mobile phone, a tablet, a console, a smart wearable device (e.g., a smart watch, etc.), and the like.

FIG. 2 is an exemplary block diagram of a temperature control device according to some embodiments of the present application. The temperature control device 140 may include an acquisition module 210, a temperature adjustment curve determination module 220, and a temperature adjustment module 230. The connections between the modules within the system may be wired, wireless, or a combination of both. Any one of the modules may be local, remote, or a combination of the two. The correspondence between the modules may be one-to-one, or one-to-many. For example, the temperature control device 140 may include a plurality of acquisition modules 210 and a plurality of temperature adjustment modules 230. Each of the temperature adjustment modules 230 may communicate with one of the acquisition modules 210, respectively, to acquire corresponding temperature information (e.g., real-time temperature and set temperature) of a portion of the wheelchair in contact with the user's body. For another example, the temperature adjustment device 100 may include a plurality of acquisition modules 210 and one temperature adjustment module 230. The temperature adjustment module 230 may communicate with the plurality of acquisition modules 210 to acquire corresponding temperature information of the target site.

The obtaining module 210 is configured to obtain temperature information. The temperature information may include information related to temperature adjustment, such as real-time temperature of a portion of the wheelchair in contact with the user's body, set temperature, parameter information of a temperature adjustment curve, and/or set value information of temperature adjustment. The obtaining module 210 may obtain the temperature information via the display 120, the input device 150, and/or a network.

The obtaining module 210 is configured to obtain a real-time temperature and a set temperature of a portion of the wheelchair in contact with a body of the user. The site may include a site on the wheelchair that is in contact with tissue of the hands, legs, head, back, abdomen, buttocks, etc. The real-time temperature of the site may be sensed in real-time by a temperature sensor 130 placed at the site. When the user is in the wheelchair, the temperature sensor 130 may sense the ambient temperature of the tissue of the user's body corresponding to the location. The tissue may include one or more of hand, leg, head, back, abdomen, hip, etc. For example, the temperature sensor 130 may be disposed on a surface of the wheelchair (e.g., at the back of the chair, at the seat cushion) for sensing the ambient temperature around the back and buttocks of the user. As another example, temperature sensors 130 may be located in insulating blanket 110, leg insulating blanket 110-6, head insulating blanket 110-4, and hand insulating blanket 110-2 for sensing the ambient temperature of the user's abdomen, legs, head, and hands.

The set temperature of the part may be the ambient temperature of the part desired by the user or may be the optimum temperature of the human body. At the optimum temperature of human body, the human body has no cold and heat feeling, and the capillary vessels in the body are in diastolic equilibrium. The set temperature of the site may be set by the user or determined by a temperature regulation curve. In some embodiments, the user may self-set the ambient temperature that the site is desired to achieve via the display 120 and/or the input device 150. In some embodiments, the obtaining module 210 may determine the set temperature of the location based on the temperature adjustment curve according to the location of the location and the user information. The temperature regulation curve reflects the relationship between different parts of the wheelchair and the set temperature. The set temperature of the temperature regulation curve may be the optimum temperature of the human body for different body tissues. The obtaining module 210 may obtain the temperature adjustment curve from the temperature adjustment curve determining module 220.

In some embodiments, the obtaining module 210 may also be configured to obtain parameter information of the temperature adjustment curve. The parameters of the temperature regulation curve may include user parameters and weather parameters. The user parameters may include one or a combination of gender, age, medical information, etc. The weather parameters may include one or a combination of air temperature, wind power level, air humidity, and the like. In some embodiments, the obtaining module 210 may obtain the user parameter and the weather parameter from the display 120 and/or the input device 150. In some embodiments, the obtaining module 210 may determine the location of the user from the network, and further determine weather information of the location of the user. Based on the weather information, the obtaining module 210 may obtain weather parameters of the temperature adjustment curve.

In some embodiments, the obtaining module 210 may also be configured to obtain temperature adjusted set point information. The set value information is used to determine whether the thermostat 160 needs to be driven for heating or cooling. The setting value information may include a first setting value and a second setting value. The first set value is used for judging whether refrigeration is needed or not when the real-time temperature is higher than the set temperature. The second set value is used for judging whether heating is needed or not when the real-time temperature is lower than the set temperature. The first setting value and the second setting value may be set by a user through the display 120 and/or the input device 150.

A temperature adjustment curve determination module 220 for determining a temperature adjustment curve. The temperature regulation curve reflects the relationship between different parts of the wheelchair and the set temperature. For example, the temperature adjustment curve may be represented by an x-y coordinate system, where the x-coordinate represents different locations of the wheelchair and the y-coordinate represents corresponding set temperatures for the different locations of the wheelchair. Each point of the temperature regulation curve represents a location of the wheelchair and a corresponding set temperature for that location. The set temperature corresponding to the location may be a human optimum temperature of a human tissue corresponding to the location.

In some embodiments, the temperature adjustment curve may be obtained based on a machine learning model. The machine learning model may include one or a combination of several of a neural network model, a support vector machine model, a random forest model, and a logistic regression model. The temperature adjustment curve determination module 220 may determine a temperature adjustment curve based on the user parameter and the weather parameter. The temperature adjustment curve determination module 220 may acquire the user parameter and the weather parameter through the acquisition module 210. In some embodiments, the temperature adjustment profile may be determined based on a combination of one or more characteristics of the user's gender, the user's age, air temperature, wind direction, wind level, air humidity, and the like. For example, in winter when the wind level is large (for example, when the wind level is 6 or more), a temperature adjustment curve adapted to the climate can be obtained by learning the relevant features by the machine learning model. For another example, in summer when the air humidity is high (for example, when the relative humidity is greater than 65%), the temperature regulation curve adapted to the summer weather can be obtained through the learning of the relevant features by the machine learning model.

The thermostat module 230 may provide thermostat information to the thermostat 100 and generate related control commands to drive the thermostat 160 to heat or cool. The temperature adjustment module 230 may receive the real-time temperature and the set temperature of the same portion acquired by the acquisition module 210, and generate a difference value between the real-time temperature and the set temperature. The temperature difference may be positive, negative, or zero. When the temperature difference is positive, indicating that the real-time temperature is higher than the set temperature, cooling by thermostat 160 may be required. When the temperature difference is negative, indicating that the real-time temperature is lower than the set temperature, heating by the thermostat 160 may be required. When the temperature difference is zero, it indicates that the temperature is right, and temperature adjustment by the temperature adjustment device 160 is not necessary. For example, temperature adjustment module 230 may receive a head set temperature input by a user via input device 150 and a real-time head temperature sensed by temperature sensor 130 located on head warming blanket 110-4, and determine a head temperature difference. The temperature difference of the head may indicate whether the real-time temperature of the user's head needs to be adjusted.

The temperature adjustment module 230 may receive the first set value and the second set value obtained by the obtaining module 210, make a decision by comparing the difference, and generate a control command to drive the temperature adjustment device 160 to heat or cool the corresponding portion. In some embodiments, when the real-time temperature is higher than the set temperature by more than the first set value, the thermostat module 230 controls the thermostat 160 to cool until the difference is equal to or less than the first set value; when the real-time temperature is lower than the set temperature by a difference greater than the second set value, the thermostat module 230 controls the thermostat 160 to heat until the difference is equal to or less than the second set value. In some embodiments, the temperature adjustment module 230 may be implemented by one or more control elements or devices.

FIG. 3 is a schematic diagram of an exemplary process for regulating temperature, shown in some embodiments according to the present application. The process 300 for adjusting the temperature can be applied to the temperature adjustment apparatus shown in fig. 1. For example, the process may be stored in a non-transitory memory in the form of a set of instructions and invoked and executed by temperature control device 140.

At step 310, the temperature control device 140 (e.g., the obtaining module 210 in the temperature control device 140) may obtain the real-time temperature of the portion of the wheelchair in contact with the user's body from the temperature sensor 130. In some embodiments, the portion of the wheelchair that contacts the user's body may include a portion of the wheelchair that contacts tissue such as hands, legs, head, back, abdomen, hips, and the like. Such as at the seat back, at the seat cushion, at the armrests, etc. The real-time temperature of the site may be sensed in real-time by a temperature sensor 130 placed at the site. In some embodiments, the temperature sensor 130 may sense the ambient temperature of the tissue of the user's body corresponding to the location when the user is located on the wheelchair. The tissue may include one or more of hand, leg, head, back, abdomen, hip, etc. For example, the temperature sensor 130 may be disposed on a surface of the wheelchair (e.g., at the back of the chair, at the seat cushion) for sensing the ambient temperature around the back and buttocks of the user. As another example, temperature sensors 130 may be located in abdomen warming blanket 110-8, leg warming blanket 110-6, head warming blanket 110-4, and hand warming blanket 110-2 for sensing the ambient temperature of the abdomen, legs, head, and hands of the user.

At step 320, the temperature control device 140 (e.g., the obtaining module 210 in the temperature control device 140) may obtain a set temperature of a portion of the wheelchair in contact with the user's body. The location may be the same as the location in step 310. The set temperature of the site may be set by the user or determined by a temperature regulation curve. In some embodiments, the temperature control device 140 may obtain the set temperature of the portion input by the user from the display 120 and/or the input device 150. The set temperature of the portion input by the user may refer to an ambient temperature that the user desires the portion to reach. In some embodiments, the temperature control device 140 may obtain the set temperature of the site from the temperature adjustment curve determination module 220. For example, the temperature control device 140 may obtain a temperature adjustment curve currently corresponding to the user from the temperature adjustment curve determining module 220, and obtain a set temperature corresponding to the location from the temperature adjustment curve based on the location of the location. The temperature regulation curve reflects the relationship between different parts of the wheelchair and the set temperature or recommended temperature. The recommended temperature in the temperature regulation curve may mean that the ambient temperature of a certain part and/or its corresponding body tissue is the optimum temperature of the human body. At the optimum temperature of human body, the human body has no cold and heat feeling, and the capillary vessels in the body are in diastolic equilibrium. The optimum temperature of different tissues of human body can be same or different.

In step 330, the temperature control device 140 (e.g., the temperature adjustment module 230 in the temperature control device 140) may drive the temperature adjustment device 160 to heat or cool according to the temperature difference between the real-time temperature and the set temperature of the portion of the wheelchair in contact with the user's body. The temperature difference may be positive, negative, or zero. When the temperature difference is positive, indicating that the real-time temperature is higher than the set temperature, cooling by thermostat 160 may be required. When the temperature difference is negative, indicating that the real-time temperature is lower than the set temperature, heating by the thermostat 160 may be required. When the temperature difference is zero, it indicates that the temperature is right, and temperature adjustment by the temperature adjustment device 160 is not necessary. The temperature control device 140 may determine whether the thermostat 160 needs to be driven for heating or cooling based on the difference, the first set value, and the second set value. When the real-time temperature is higher than the set temperature, the temperature control device 140 determines whether the thermostat 160 needs to be driven for cooling based on the first set value. The first set value may be set by the temperature adjustment device 100 or may be adjusted according to actual conditions. The first set value may be 2 ℃, 3 ℃, 5 ℃, etc. When the real-time temperature is lower than the set temperature, the temperature control device 140 determines whether the temperature adjustment device 160 needs to be driven for heating based on the second set value. The second set value may be set by the temperature adjustment device 100 or may be adjusted according to actual conditions. The second set value may be 2 ℃, 3 ℃, 5 ℃, etc. The second set point may be the same as or different from the first set point.

In some embodiments, when the difference between the real-time temperature and the set temperature is greater than the first set value, the temperature control device 140 drives the temperature adjustment device 160 to perform cooling until the difference is equal to or less than the first set value; when the difference between the real-time temperature and the set temperature is greater than the second set value, the temperature control device 140 drives the temperature adjustment device 160 to heat until the difference is equal to or less than the second set value.
