Description

Technical Field

[0001] This invention relates to the field of automotive safety products technology, and more specifically, to a temperature regulation system, its control method and device, and a child safety seat. Background Technology

[0002] With the increasing popularity of cars, children are spending more time riding in them, leading to more frequent use of child safety seats. Improving the comfort of child safety seats has become a key factor influencing their sales.

[0003] Currently, car air conditioning systems cannot quickly and effectively regulate the temperature of the passenger compartment to children in car seats. For example, in summer, the lining and protective materials can cause the backrest of the car seat to become stuffy and poorly ventilated between the seat and the passenger; in winter, even with the car heater on, the car seat remains cold. To address this issue, existing technology incorporates a temperature control system within the car seat. This system includes heating and / or cooling components, a fan, and air vents. When the temperature control system is off, the heating and / or cooling components, fan, and air vents are all off. When the system is on, the heating components heat the seat / the cooling components cool it, and the fan and air vents are on. The fan delivers hot or cold air from the air vents to the surface of the car seat, thus heating or cooling it.

[0004] However, as a safety product, child safety seats need to meet electrical safety standards. Their power should not exceed the power threshold specified in the standard. Within this power range, due to the air heat conduction effect, after the fan sends hot or cold air out of the air outlet, the air heat conduction effect causes heat or cold to dissipate, resulting in poor heating or cooling effect of the child safety seat. Summary of the Invention

[0005] To address at least one of the aforementioned problems, the present invention first provides a temperature regulation system control method, comprising the following steps: when the temperature regulation system meets a first preset switching condition, controlling the temperature regulation system to switch from an energy storage state to an energy release state; wherein, the energy storage state includes: temperature regulation function on, fan and air outlet off; the energy release state includes: temperature regulation function on, fan and air outlet on; when the temperature regulation system meets a second preset switching condition, controlling the temperature regulation system to switch from the energy release state to the energy storage state.

[0006] Optionally, the first preset switching condition includes: the duration for which the temperature regulation system is in the energy storage state is greater than or equal to the first preset duration.

[0007] Optionally, the first preset switching condition further includes: the temperature within the temperature regulation system exceeds the safe temperature range; the temperature regulation system control method further includes:

[0008] Determine whether the temperature within the temperature control system exceeds the safe temperature range;

[0009] If so, the temperature regulation system is determined to meet the first preset switching condition;

[0010] If not, then determine whether the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration. If the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration, then determine that the temperature regulation system meets the first preset switching condition.

[0011] Optionally, the second preset switching condition includes: the duration of the temperature regulation system in the energy release state is greater than or equal to the second preset duration, and the ambient temperature at the air outlet has not reached the target temperature.

[0012] Optionally, the temperature regulation system control method further includes: when the duration of the temperature regulation system in the energy release state is greater than or equal to a third preset duration, acquiring the ambient temperature of the air outlet, wherein the third preset duration is less than or equal to the second preset duration; determining whether the ambient temperature of the air outlet has reached the target temperature; if so, returning to the step of acquiring the ambient temperature of the air outlet.

[0013] Optionally, the temperature regulation system control method further includes: when the ambient temperature at the air outlet reaches the target temperature, controlling the temperature regulation system to standby; when the temperature regulation system is in standby mode, if it is detected that the ambient temperature at the air outlet has not reached the target temperature, and the difference between the ambient temperature at the air outlet and the target temperature is greater than or equal to a preset difference, controlling the temperature regulation system to enter the energy storage state.

[0014] Optionally, the temperature regulation system control method further includes: starting the temperature regulation system; and controlling the temperature regulation system to enter the energy storage state.

[0015] Compared to existing technologies, the temperature regulation system control method in this invention controls the temperature regulation system to cycle between energy storage and energy release states after startup. In the energy storage state, heating is turned on while the fan and air outlet are closed, allowing heat to accumulate within the sealed space of the temperature regulation system and raising the temperature of the air inside. After switching from the energy storage state to the energy release state, the hot air that has undergone energy storage in the sealed space is blown out and acts on the environment around the air outlet, quickly adjusting the ambient temperature around the air outlet to the target temperature required by the user. This achieves the goal of increasing the outlet temperature under limited power, thereby achieving the heating, heat dissipation, ventilation, or cooling effects that meet the user's needs under power constraints.

[0016] In addition, the present invention also provides a control device for a temperature regulation system, including a readable storage medium storing a computer program and a processor, wherein the computer program is read and executed by the processor to implement the temperature regulation system control method described above.

[0017] In addition, the present invention also provides a temperature regulation system, including temperature regulating components, a fan, an air outlet, and a control device for the temperature regulation system as described above.

[0018] In addition, the present invention also provides a child safety seat, including a control device for the temperature regulation system as described above, or including the temperature regulation system as described above.

[0019] Compared to existing technologies, the child safety seat described in this invention and the temperature regulation system control method described above have the same advantages over existing technologies, which will not be repeated here. Attached Figure Description

[0023] Figure 4 This is a schematic diagram of the temperature control system of the present invention. Detailed Implementation

[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0025] This invention provides a temperature regulation system control method. The temperature regulation system includes temperature-regulating components, a fan, and an air outlet. The temperature-regulating components include heating components and / or cooling components. The heating components are used for heating, and the cooling components are used for cooling. The temperature regulation function in this document refers to either a heating or cooling function. The fan delivers warm / cool air from the air outlet to the surface of the child safety seat, thereby heating or cooling the child safety seat. For ease of description, heating is used as an example to explain the steps and effects of the temperature regulation system control method in various embodiments of this invention. Cooling is similar to heating and will not be described in detail. Figure 1 As shown, based on the temperature regulation system, the temperature regulation system control method includes:

[0026] When the temperature regulation system meets the first preset switching condition, the temperature regulation system is controlled to switch from the energy storage state to the energy release state; wherein, the energy storage state includes: the temperature regulation function is turned on, and the fan and air outlet are turned off; the energy release state includes: the temperature regulation function is turned on, and the fan and air outlet are turned on; when the temperature regulation system meets the second preset switching condition, the temperature regulation system is controlled to switch from the energy release state to the energy storage state.

[0027] After the temperature regulation system is started, during the execution of the temperature regulation system control method of this embodiment of the invention, the temperature regulation system cyclically switches between an energy storage state and an energy release state. During the switching between the energy storage state and the energy release state, the temperature regulation function remains unchanged. For example, if the energy storage state is for heating, the heating function remains active when switching to the energy release state; if the energy storage state is for cooling, the cooling function remains active when switching to the energy release state. After the temperature regulation system is started, it can first enter the energy storage state for energy storage, or it can first enter the energy release state and then switch to the energy storage state.

[0028] When the temperature control system is in energy storage mode, heating is on, and the fan and air outlet are closed. At this time, the interior of the temperature control system is a closed space. The system continuously heats the air, accumulating heat within this closed space and storing energy in the airflow. As the heat increases, the air temperature within the closed space also rises. The temperature change of the hot air within the closed space can be calculated using the following formula:

[0029] △T1=Q / cm=P·t1 / cm

[0030] Where △T1 refers to the temperature change of the hot air in the enclosed space, t1 is the duration of the temperature regulation system in the energy storage state, c is the specific heat capacity, m is the mass, Q is the actual energy generated by the temperature regulation system within t1, P is the actual power, P=r·P0, r is the conversion rate, P0=U·I, U is the voltage, and I is the current.

[0031] When the temperature control system meets the first preset switching condition, it switches from an energy storage state to an energy release state. That is, heating continues, but the fan and air outlet are activated, turning the enclosed space inside the system into an open space. The warmer air from the enclosed space is blown out by the fan from the air outlet, affecting the surrounding environment and regulating its temperature. When the energy release state is short-lived, the air blown out is warmer air that has undergone energy storage in the enclosed space. When the energy release state is long-lived, over time, the warmer air that has undergone energy storage in the enclosed space is blown out, gradually becoming cooler air that has not undergone energy storage in the enclosed space. Clearly, the temperature of the air that has undergone energy storage in the enclosed space is higher than that of the air that has not.

[0032] When the temperature control system meets the second preset switching condition, it switches from an energy release state to an energy storage state. That is, heating continues, but the fan and air vents are turned off, and the space inside the temperature control system becomes a closed space again. This cyclical switching ensures that the temperature control system regulates the ambient temperature to meet the user's actual application needs.

[0033] Given the actual usage scenarios, the heating function of child safety seats does not need to be long-term or continuous. Therefore, this embodiment of the invention adopts intermittent heating control, using a cycle of "energy storage and heat preservation - heat release" to achieve incremental temperature control under limited power. Incremental temperature control means that a certain temperature rise is obtained in each "energy storage and heat preservation - heat release" cycle, and the temperature rise of each cycle is accumulated after multiple cycles until the target temperature is reached.

[0034] In existing technologies, temperature control systems typically turn heating, fan, and air vents on or off simultaneously. During normal operation after the temperature control system is started, only heating can be turned on, while the fan and air vents are open. The heat generated by the heating elements is directly proportional to their power; the power determines the amount of heat generated. Because child safety seats are safety products for children and are affected by the automotive environment, they generally require a voltage of ≤24V and a current of ≤10A. In practice, they are usually made of 12V and a current of ≤5A, meaning the actual power is ≤60W, which is low and generates little heat. Furthermore, the installation environment, structural characteristics, and fabric covering of child safety seats can also affect the temperature control system, making it difficult to provide sufficient and continuous heating. Therefore, the above-mentioned approach in existing technologies cannot quickly adjust the ambient temperature at the air vent to the user's desired target temperature. In this embodiment of the invention, after the temperature regulation system is started, it cycles between an energy storage state and an energy release state. In the energy storage state, heating is turned on while the fan and air outlet are closed, allowing heat to accumulate within the sealed space inside the temperature regulation system and raising the temperature of the air inside the system. After switching from the energy storage state to the energy release state, a portion of the hot air that had undergone energy storage in the sealed space and the hot air generated during the energy release state are combined and blown out, acting on the environment around the air outlet. This can quickly adjust the ambient temperature around the air outlet to the target temperature actually required by the user, achieving an increase in air outlet temperature under limited power, thereby achieving a heating effect that meets the user's heating needs under power constraints.

[0035] Optionally, the first preset switching condition includes the duration during which the temperature regulation system is in energy storage state being greater than or equal to the first preset duration.

[0036] The first preset duration can be the factory default value of the temperature control system, or it can be set by the developers based on experiments.

[0037] In energy storage mode, the temperature control system continuously operates for heating, while the fan and air outlet are closed. If the energy storage mode is short-lived, insufficient heat accumulation within the system results in a low internal air temperature, limiting its effectiveness in regulating the air outlet temperature. Therefore, when the energy storage mode lasts less than a preset duration, it remains in this state to continue accumulating energy. As the energy storage mode continues longer, the temperature within the enclosed space of the system rises. If this temperature exceeds a certain threshold, it can damage components, reduce system reliability, and increase safety risks. Furthermore, in energy storage mode, the system cannot blow out hot air to regulate the air outlet temperature. If the system remains in energy storage mode, the air outlet temperature may drop significantly, increasing the time required to adjust the air outlet temperature to the target temperature. Therefore, when the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration, it indicates that the duration of the energy storage state has reached the critical value. At this time, controlling the temperature regulation system to switch from the energy storage state to the energy release state can, on the one hand, prevent the temperature in the temperature regulation system from becoming too high, avoid damage to components, ensure high system reliability, and ensure safety. On the other hand, it can also blow out hot air in time to regulate the ambient temperature of the air outlet, avoid the "cooling time" being too long, and adjust the ambient temperature of the air outlet to the target temperature as soon as possible.

[0038] Further optionally, the first preset switching condition also includes the temperature within the temperature regulation system exceeding the safe temperature range; the temperature regulation system control method further includes:

[0039] Determine whether the temperature inside the temperature control system exceeds the safe temperature range;

[0040] If so, the temperature control system is determined to meet the first preset switching condition;

[0041] If not, determine whether the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration. If the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration, determine that the temperature regulation system meets the first preset switching condition.

[0042] The safe temperature range can be the factory default value for the temperature control system, or it can be set by developers based on experiments. By using the temperature within the temperature control system as a criterion for state switching, and first determining whether the temperature within the temperature control system exceeds the safe temperature range, and then determining the duration of the temperature control system in energy storage mode, dangerous critical states of the temperature control system can be resolved in a timely manner, preventing component damage, ensuring high system reliability, and ensuring safety.

[0043] Optionally, the second preset switching condition includes: the duration of the temperature regulation system being in the energy release state is greater than or equal to the second preset duration, and the ambient temperature at the air outlet has not reached the target temperature.

[0044] The second preset duration can be the factory default setting. The target temperature can be the factory default setting or set by the user.

[0045] The air vent can be installed on the surface of the child safety seat, specifically on the backrest surface. A temperature sensor can be installed at the air vent location, or in a nearby location, such as at a distance less than a preset threshold between the backrest surface and the air vent. The temperature measured by the sensor is taken as the ambient temperature at the air vent.

[0046] The ambient temperature at the air outlet can be acquired in real time after the temperature control system enters the energy release state to determine whether the target temperature has not been reached. Alternatively, the ambient temperature at the air outlet can be acquired at a certain point in time after the temperature control system enters the energy release state, for example, when the duration of the energy release state of the temperature control system is equal to a second preset duration, to determine whether the target temperature has not been reached.

[0047] Therefore, by limiting the second preset switching condition to include the duration of the energy release state being greater than or equal to the second preset duration, it is possible to avoid the inability to effectively regulate the outlet ambient temperature due to the short duration of the energy release state. At the same time, the second preset switching condition also includes the outlet ambient temperature not reaching the target temperature. When the outlet ambient temperature reaches the target temperature, there is no need to increase the outlet temperature, that is, there is no need to switch to the energy storage state. However, when the outlet ambient temperature does not reach the target temperature, the outlet temperature needs to be increased. When the duration of the energy release state is simultaneously greater than or equal to the second preset duration, the system switches to the energy storage state.

[0048] This invention, through limiting a first preset switching condition including the duration of the temperature regulation system in energy storage state being greater than or equal to a first preset duration, and a second preset switching condition including the duration of the temperature regulation system in energy release state being greater than or equal to a second preset duration, and the ambient temperature at the air outlet not reaching the target temperature, divides time into time blocks and performs energy storage and energy release switching at different times, thereby achieving incremental temperature control by superimposing energy to meet the actual application needs of users.

[0049] Optionally, the temperature regulation system control method further includes:

[0050] When the duration of the temperature control system in the energy release state is greater than or equal to the third preset duration, the ambient temperature at the air outlet is obtained, wherein the third preset duration is less than or equal to the second preset duration;

[0051] Determine whether the ambient temperature at the air outlet has reached the target temperature;

[0052] If so, return to the step of obtaining the ambient temperature of the air outlet, and after obtaining the ambient temperature of the air outlet, continue to execute the steps following that step;

[0053] If not, determine whether the duration of the temperature regulation system in the energy release state is greater than or equal to the second preset duration. If so, determine that the temperature regulation system meets the second preset switching condition.

[0054] By acquiring the outlet ambient temperature only when the duration of the energy release state is greater than or equal to the third preset duration, the outlet ambient temperature can be acquired after the temperature regulation system has adjusted the outlet ambient temperature for a period of time. This reduces invalid temperature judgment operations and wastes operating resources.

[0055] Optionally, when the ambient temperature at the air outlet reaches the target temperature, the temperature control system continues to operate in the energy release state, thereby continuously regulating the ambient temperature at the air outlet. This reduces the situation where the temperature changes from reaching the target temperature to not reaching the target temperature due to a decrease in the ambient temperature at the air outlet during heating, or the situation where the temperature changes from reaching the target temperature to not reaching the target temperature due to an increase in the ambient temperature at the air outlet during cooling.

[0056] Optionally, the temperature regulation system control method further includes:

[0057] When the ambient temperature at the air outlet reaches the target temperature, the temperature control system will be put into standby mode.

[0058] When the temperature control system is in standby mode, if it detects that the ambient temperature at the air outlet has not reached the target temperature, and the difference between the ambient temperature at the air outlet and the target temperature is greater than or equal to a preset difference, the temperature control system will be controlled to enter the energy storage state.

[0059] When the ambient temperature at the air outlet reaches the target temperature, the temperature control system can be put into standby mode to stop heating and save energy. While in standby mode, the system monitors the ambient temperature at the air outlet in real-time or periodically, determining its relationship to the target temperature. If the ambient temperature at the air outlet drops below the target temperature (i.e., has not reached the target temperature), and the difference between the ambient temperature at the air outlet and the target temperature is greater than or equal to a preset difference, it indicates that reheating is needed. At this point, the temperature control system enters an energy storage state, initiating a new cycle of "energy storage and heat preservation - heat release" to adjust the ambient temperature at the air outlet to the user's desired temperature.

[0060] Optionally, the temperature regulation system control method further includes: starting the temperature regulation system; controlling the temperature regulation system to enter the energy storage state.

[0061] Specifically, after the temperature regulation system is started, it is first controlled to enter the energy storage state, so that heat can accumulate in the closed space inside the temperature regulation system as soon as possible, and the internal temperature of the temperature regulation system can be raised to obtain a warmer temperature than that of normal heating in existing technologies. This achieves the goal of increasing the outlet air temperature of the temperature regulation system under limited power conditions, so as to obtain a better temperature regulation effect.

[0062] In one implementation, such as Figure 2 As shown, the temperature regulation system control method includes:

[0063] S1, activate the temperature control system;

[0064] S2, control the temperature regulation system to enter the energy storage state, wherein the energy storage state includes: temperature regulation function is turned on, fan and air outlet are turned off;

[0065] S3, control the temperature regulation system to remain in the energy storage state for a first preset duration, or control the temperature regulation system to remain in the energy storage state until the temperature within the temperature regulation system exceeds the safe temperature range. When the duration of the temperature regulation system in the energy storage state is greater than or equal to the first preset duration, or when the temperature within the temperature regulation system exceeds the safe temperature range, control the temperature regulation system to switch to the energy release state, wherein the energy release state includes: temperature regulation function on, fan and air outlet on;

[0066] S4: Control the temperature regulation system to remain in the energy release state for a second preset duration, then determine whether the ambient temperature at the air outlet has reached the target temperature. If so, continue working or standby until the ambient temperature at the air outlet does not reach the target temperature, then return to execute S2-S4; otherwise, return to execute S2-S4. Alternatively, if the duration of the temperature regulation system in the energy release state is greater than or equal to the second preset duration, and the ambient temperature at the air outlet has not reached the target temperature, return to execute S2-S4; if the duration of the temperature regulation system in the energy release state is less than the second preset duration, and the ambient temperature at the air outlet has not reached the target temperature, the temperature regulation system continues to maintain the energy release state; if the duration of the temperature regulation system in the energy release state is greater than or equal to the second preset duration, but the ambient temperature at the air outlet has reached the target temperature, control the temperature regulation system to continue working until the ambient temperature at the air outlet does not reach the target temperature, then return to execute S2-S4.

[0067] For ease of understanding, the following is a heating control example: (Reference) Figure 3 ,exist Figure 3 In the coordinate system shown, the horizontal axis represents time t, and the vertical axis represents the ambient temperature at the air outlet T. t1, t3, and t5 represent the time periods of the energy storage state, and t2, t4, and t6 represent the time periods of the energy release state. The safe temperature range is less than 45℃, and the target temperature T is... 目=20℃, initial ambient temperature is T0=5℃, and the power of the heating element is 60W. Heating begins at 60W and continues until the outlet ambient temperature reaches the target temperature of 20℃. Specifically, the first cycle t1-t2 begins, initially in energy storage mode, then switching to energy release mode. During time period t1, the temperature rise of the outlet ambient temperature corresponding to time period t1 is recorded as △T1, and the temperature rise of the outlet ambient temperature corresponding to the newly generated heat during time period t2 is recorded as △Tr1. During time period t1, heat accumulates in the enclosed space. The outlet and fan are only turned on after switching to energy release mode. The high heat accumulated during time period t1 acts on the outlet environment, resulting in a larger temperature rise of the outlet ambient temperature corresponding to time period t1. During time period t2, the newly generated heat continues to heat at 60W power because the power remains unchanged. However, since it is in an open space, heat dissipation is achieved through air conduction, so the temperature rise of the outlet ambient temperature △T1 > △Tr1. At the end of time period t2, the temperature rise of the outlet ambient temperature is △T1 + △Tr1. Assuming △T1 is 4℃ and △Tr1 is 3℃, the ambient temperature at the air outlet at the end of the first cycle is T0 + △T1 + △Tr1 = 5℃ + 4℃ + 3℃ = 12℃. Assign 12℃ to T0.

[0068] At this point, the ambient temperature at the air outlet has not yet reached the target temperature of 20℃. Therefore, the next cycle t3-t4 continues, switching from the energy release state to the energy storage state, continuing heating, and turning off the air outlet and fan. During the time period t3, the temperature rise of the ambient temperature at the air outlet corresponding to the time period t3 is recorded as △T3. After the switching condition is met, the state switches from energy storage to energy release, continuing heating, and turning on the air outlet and fan. The temperature rise of the ambient temperature at the air outlet corresponding to the newly generated heat during the time period t4 is recorded as △Tr2. Assuming that △T3 is 4℃ and △Tr2 is 3℃, the ambient temperature at the end of the second cycle is T0+△T3+△Tr2=12℃+4℃+3℃=19℃. 19℃ is assigned to T0.

[0069] At this point, the ambient temperature at the air outlet is 19℃, which is still below the target temperature of 20℃. Therefore, the next cycle t5-t6 continues, switching from the energy release state to the energy storage state to continue heating, while the air outlet and fan are turned off. The temperature rise of the ambient temperature at the air outlet during time period t5 is recorded as △T5. After the switching conditions are met, the system switches from the energy storage state to the energy release state to continue heating, while the air outlet and fan are turned on. The temperature rise of the ambient temperature at the air outlet corresponding to the newly generated heat during time period t6 is recorded as △Tr3. Assuming △T5 is 4℃ and △Tr3 is 3℃, if all the warm air output this time acts on the air outlet environment, it can raise the air outlet environment temperature by 7℃. Therefore, during the process of the warm air output during time period t6 acting on the air outlet environment, the air outlet environment temperature will be raised to 20℃, reaching the target temperature. Subsequently, the temperature regulation system can be controlled to standby, waiting for the air outlet environment temperature to drop to the preset start-up temperature before restarting, or it can remain in the energy release state, waiting for the air outlet environment temperature to meet the switching conditions before switching back to the energy storage state.

[0070] It is important to note that at the beginning of time period t2, when the system is just switching from energy storage to energy release, the high heat accumulated during time period t1 is just released from the temperature control system. At this time, the temperature of the released hot air is relatively high, causing the temperature sensor measuring the ambient temperature at the air outlet to instantly reach the highest value of time period t2. Subsequently, due to thermal conduction, the heat dissipates into the air, and the temperature measured by the temperature sensor decreases until it reaches a relatively stable value, i.e., the ambient temperature at the air outlet at the end of the first cycle is T0 + ΔT1 + ΔTr1 = 12℃. The subsequent cycles are similar, and will not be elaborated here.

[0071] Another embodiment of the present invention provides a control device for a temperature regulation system, including a readable storage medium storing a computer program and a processor. The computer program is read and executed by the processor to implement the temperature regulation system control method described above.

The cavity 3 has an inlet and an outlet. An inlet baffle 4 is movably connected to the inlet for closing or opening the inlet, and an outlet baffle 5 is movably connected to the outlet for closing or opening the outlet. Both the inlet baffle 4 and the outlet baffle 5 can be driven by a motor. When in the energy storage state, the outlet baffle 5 closes the outlet, and the inlet baffle 4 closes the inlet, making the cavity 3 fully closed. When in the energy release state, the outlet baffle 5 opens the outlet, and the inlet baffle 4 opens the outlet. The opening mechanism allows the cavity 3 to be in an open state, enabling heat exchange between the air inside and outside the cavity 3. A temperature sensor 2 is installed at the air outlet 1 to detect the ambient temperature of the air outlet 1. The temperature sensor 2 can also be installed near the air outlet. The temperature control component 8, fan 7, temperature sensor 2, and motor are all electrically connected to the control board 6. The fan 7 is used to blow the air inside the cavity 3 to the air outlet 1 when the energy is released. The temperature control component 8 is a heating component and / or a cooling component. The cavity 3 is also wrapped with an insulation layer to keep the air inside the cavity 3 warm.

[0074] The heating element can be a PTC heater or a resistance wire. The cooling element can be a semiconductor refrigeration chip.

[0075] The fan 7 is used to deliver hot or cold air from the air outlet 1 to the surface of the child safety seat, thereby heating or cooling the child safety seat.

[0076] The temperature regulation system control device is used to control the heating element to heat, or to control the cooling element to cool, and also to control the fan 7 to turn on or off, and the motor connected to the air outlet baffle 5 to control the opening / closing of the air outlet 1.

[0077] The temperature regulation system of this invention has the same beneficial effects as the control device of the temperature regulation system described above compared with the prior art, and will not be repeated here.
