[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0024] This utility model embodiment provides an automotive ambient cabin temperature acquisition and regulation system. Please refer to [link / reference]. Figure 1 , Figure 2It mainly includes a heat engine for regulating the temperature inside the environmental chamber 1 and a data acquisition module for detecting the temperature inside the environmental chamber 1. The output port 2 of the heat engine is located inside the environmental chamber 1, and the output port 2 includes multiple branch ports facing different directions. The data acquisition module includes multiple data acquisition components, and at least one data acquisition component is set in the space facing each branch port. The data acquisition component contains multiple data acquisition units, and the multiple data acquisition units are arranged in a three-dimensional structure in the space facing each branch port. The data acquisition module is electrically connected to the heat engine, and the heat engine is used to regulate the output temperature of the corresponding branch port according to the detection results of the data acquisition components, so that the temperature in the space facing each branch port is consistent.

[0025] In this application, each data acquisition component corresponds to a heating direction of the heat engine. The detection results of the data acquisition components characterize the temperature of the space in that direction. The data acquisition components can specifically be thermocouple sensors or other temperature sensors. Based on the comparison between the real-time temperature detected by the data acquisition components and the set temperature, the outlet air temperature of the heat engine is adjusted to make the temperature in various parts of the environmental chamber 1 more uniform. This not only makes the temperature in the environmental chamber 1 closer to the set value, but also makes the perceived temperature of the vehicle in the environmental chamber 1 more uniform, providing a good testing environment.

[0026] Understandably, the heat engine can be externally controlled by a main unit for setting and regulating the temperature, monitoring the ambient temperature inside the cabin, etc.

[0027] Each acquisition component may contain multiple acquisition units, which are arranged in a three-dimensional structure in the heating direction corresponding to the acquisition component. This allows the multiple acquisition units to collect as much temperature data as possible within the space, so as to adjust the heating effect of the heat engine and achieve the goal of making the temperature inside the cabin more uniform.

[0028] The heat engine can be a self-heating / cooling device that can directly generate heat or cold energy and input it into the environmental chamber 1; or it can be a blower box that is connected to external heating / cooling equipment to deliver heat or cold energy into the environmental chamber 1.

[0029] In the embodiments of this application, heat can be transferred to the output port 2 through structures such as air ducts, and then distributed to various parts of the environmental chamber 1 from the output port, so that the temperature in various parts of the chamber tends to be uniform.

[0030] The output port can be located on the top of the environmental chamber 1, and can be fixed or rotating between the environmental chamber 1 and the output port.

[0031] When the output port 2 and the environmental chamber 1 are fixedly installed, the air duct can be directly connected to the output port 2, and the orientation of each branch port of the output port 2 can be adjusted to be relative to the corresponding acquisition component. At this time, each branch port corresponds to a different direction, which can uniformly heat the environmental chamber 1 and ensure that the temperature inside the environmental chamber 1 tends to be uniform.

[0032] When the output port 2 and the environmental chamber 1 are rotatably connected, a rotatable joint can be added between the duct and the output port 2 so that the output port 2 is not affected by the duct when rotating, and the normal airflow is maintained. At this time, the correspondence between the branch port and the acquisition component is variable. Based on the symmetrical layout of the acquisition component, bidirectional verification can be implemented. Even if a local acquisition component fails, normal operation can still be maintained, and the current test can continue normally.

[0033] Specifically, the rotatable output port 2 can rotate at an angle equal to the included angle of the branch port or the sum of several included angles, so that the rotated branch port still forms an effective correspondence with the symmetrically arranged acquisition components, thereby adjusting the correspondence between the acquisition components and the branch ports.

[0034] In this application, multiple data acquisition components are installed inside the cabin. The average temperature collected by these components is taken as the cabin temperature, which is then compared with the set temperature before temperature control is applied. Temperature control can be achieved by adjusting the airflow, heating power, cooling power, etc.

[0035] For example, taking a usage scenario that requires heating as an example, when the average temperature inside the cabin is lower than the set temperature, the heat input should be increased; when the average temperature inside the cabin is higher than the set temperature, the heat input should be reduced.

[0036] In this application, the environmental chamber 1 is a rectangular parallelepiped structure, with doors at both ends or one end for easy vehicle entry and exit. In a specific implementation, the heat engine in the environmental chamber 1 may include air outlets in two directions, corresponding to the front and rear of the vehicle respectively, to heat the environment on both sides, thereby homogenizing the temperature inside the environmental chamber 1 and making the perceived temperature in the vehicle approximately uniform.

[0037] In one specific embodiment, the heat engine includes two branch ports facing forward and backward. The branch port facing forward is the first air outlet 21, and the branch port facing backward is the second air outlet 22. The heat engine is located at the top center of the environmental chamber 1. The orientation of the first air outlet 21 corresponds to the front half of the environmental chamber 1, and the orientation of the second air outlet 22 corresponds to the rear half of the environmental chamber 1.

[0038] Correspondingly, the data acquisition module may include a first data acquisition component 3 and a second data acquisition component 4. The first data acquisition component 3 is located in the front half of the compartment facing the first air outlet 21; the second data acquisition component 4 is located in the rear half of the compartment facing the second air outlet 22; and the temperature data of the front half of the compartment and the temperature data of the rear half of the compartment are acquired respectively.

[0039] With the layout of the two acquisition components described above, the collected temperature data can represent the ambient temperature at the front and rear of the vehicle, respectively. The average value of the two can then be compared with the set temperature.

[0040] However, in real-world environments, the temperature differences between the bottom and sides of a vehicle are more pronounced than those between the two ends of the vehicle. Therefore, a third data acquisition component 5 can be installed at the bottom of the vehicle to characterize the ambient temperature at the bottom of the vehicle after it enters the environmental chamber 1. The average value of the temperature data from the three regions is calculated and then compared with the set temperature.

[0041] Of course, when calculating the average value, a weighted average method can be used, and the weights can be allocated according to the degree of impact on each region.

[0042] In one specific embodiment, the acquisition module further includes a third acquisition component 5, which is located at the bottom center of the environmental chamber 1 or directly below the heat engine, and is electrically connected to the heat engine.

[0043] In practice, if an environmental chamber 1 can only accommodate one car for testing, the position of the third acquisition component 5 can be determined according to the length of the vehicle; if an environmental chamber 1 can accommodate multiple cars for testing at the same time, multiple third acquisition components 5 can be set according to the vehicle spacing and vehicle length, so that there is a third acquisition component 5 at the bottom of each vehicle.

[0044] In the embodiments of this application, the environmental chamber 1 has a large space. If each acquisition component contains only one acquisition point, the data may have a large deviation. Therefore, each acquisition component may include multiple acquisition units to collect temperature data at multiple points in the space.

[0045] For example, the first acquisition component 3 includes multiple acquisition units, which can be arranged as follows: at least one acquisition unit is located at the upper left corner of the front half of the cabin, at least one acquisition unit is located at the upper right corner of the front half of the cabin, at least one acquisition unit is located at the lower left corner of the front half of the cabin, and at least one acquisition unit is located at the lower right corner of the front half of the cabin.

[0046] Correspondingly, the second acquisition component 4 includes multiple acquisition units, which can be arranged as follows: at least one acquisition unit is located in the upper left corner of the rear half-cabin, at least one acquisition unit is located in the upper right corner of the rear half-cabin, at least one acquisition unit is located in the lower left corner of the rear half-cabin, and at least one acquisition unit is located in the lower right corner of the rear half-cabin.

[0047] Of course, the acquisition units contained in the acquisition components in the front and rear compartments can be arranged in a matrix based on the compartment structure, so that the heating effect of the heat engine can be reflected in the data, thereby facilitating the adjustment of the heating effect and obtaining the desired vehicle temperature.

[0048] It should be clarified that the third acquisition component 5 may also include multiple acquisition units, and the arrangement of the multiple acquisition units may be as follows: at least one acquisition unit is located on the inside of the left front wheel, at least one acquisition unit is located on the inside of the right front wheel, at least one acquisition unit is located on the inside of the left rear wheel, and at least one acquisition unit is located on the inside of the right rear wheel.

[0049] Please see Figure 1 , Figure 2 Taking each acquisition component as an example, which includes four acquisition units, the acquisition units can be located in the corners near the ends of the cabin, i.e., the eight corners of the environmental cabin 1, to collect boundary temperature values ​​that are relatively far from the heat engine.

[0050] To demonstrate the difference between the boundary temperature value and the heating temperature value of the heat engine, a temperature sensor can be installed at the output port / air outlet of the heat engine to verify the stability of the heating effect of the heat engine.

[0051] In one specific embodiment, the acquisition module further includes a first temperature control sensor 11 and a second temperature control sensor 12. The first temperature control sensor 11 is located at the first air outlet 21, and the second temperature control sensor 12 is located at the second air outlet 22. Both the first temperature control sensor 11 and the second temperature control sensor 12 are electrically connected to the thermoelectric generator.

[0052] When the environmental chamber 1 is heated by the heat engine, the temperature is set to the desired value, and the detection values ​​of the first temperature control sensor 11 and the second temperature control sensor 12 are the actual values. By comparing the actual value with the desired value, the control effect of the heat engine on the temperature inside the environmental chamber 1 can be effectively adjusted.

[0053] In the embodiments of this application, the heat engine includes multiple branch ports, each branch port corresponding to a direction, and the control of each branch port can be realized by an on / off valve. An on / off valve is provided on the pipe connected to the branch port, and the opening degree, air flow rate, etc. of the branch port can be controlled by the on / off valve.

[0054] Correspondingly, taking the opening degree as an example, the heat engine can also be equipped with a control module for adjusting the opening degree of each branch port. The opening and closing valve of each branch port is electrically connected to the control module and is independently controlled by the control module.

[0055] Meanwhile, the control module is electrically connected to the acquisition module. The control module adjusts the opening degree of each branch port according to the detection results of the acquisition module, so as to achieve independent control of the output temperature of each branch port.

[0056] For example, when the temperature value detected by the first acquisition component 3 is too low, the control module adjusts the opening degree of the valve used to control the opening and closing of the first air outlet 21 to increase the amount of heat input, so that the temperature of the front half of the compartment meets the standard and is consistent with the temperature of the rear half of the compartment.

[0057] In embodiments of this application, the first air outlet 21 may include multiple front ports, which simultaneously supply air. In this case, the first temperature control sensor 11 may be suspended at the center of the multiple front ports. Taking two front ports as an example, the first temperature control sensor 11 is positioned between them, suspended in front of the front ports, and at a certain distance from them. Figure 1 , Figure 2 As shown, at this distance, the airflows of the two front ports have initially merged and have already merged, that is, the first temperature sensor 11 is located in the airflow fusion area of ​​the two front ports.

[0058] Of course, multiple front ports can also supply air to different directions. In this case, each front port can be equipped with a first temperature control sensor 11 so that the control module can control the air volume of each port in a targeted manner. The first temperature control sensor 11 can be placed in multiple ports to detect the temperature.

[0059] Since multiple front ports receive heat input through pipes connected by a branch port, the on / off valves mounted on the main branch port are no longer sufficient to control the flow rate in each front port. Therefore, a core on / off valve can be added to each front port, allowing the control module to adjust the opening degree of each front port and optimize the temperature control effect in all directions of the front compartment.

[0060] Multiple temperature sensors installed at the ports can be numbered so that they correspond to each port, allowing the control module to perform independent temperature regulation.

[0061] Similarly, the second air outlet 22 includes multiple rear ports, and the second temperature control sensor 12 is suspended at the center of the multiple rear ports or each rear port is provided with a corresponding second temperature control sensor 12.

[0062] According to the embodiments of this application, the branch ports correspond to the acquisition components. The acquisition components are preferably arranged symmetrically in the cabin, which requires that the branch ports are also arranged symmetrically. The first air outlet 21 and the second air outlet 22 mentioned above are arranged symmetrically, located at the front end and rear end of the output port, respectively. Similarly, a left air outlet and a right air outlet can be provided on both sides of the output port 2. Based on these four basic air outlets, since the acquisition components are relatively fixed in the cabin, when the output port 2 is rotated and adjusted, the first air outlet 21 can be rotated to the original position of the second air outlet 22. The first acquisition component 3 corresponds to the second air outlet 22, and the second acquisition component 4 corresponds to the first air outlet 21. At the same time, the left air outlet and the right air outlet are synchronously swapped. The heat output and wind force of each air outlet can remain unchanged, only the orientation changes.

[0063] Based on this, the heating effect of the air outlet can be verified and controlled bidirectionally by symmetrically distributed acquisition components. Even if the acquisition component in a certain direction fails, the temperature in the environmental chamber 1 can be kept uniform by continuously adjusting and resetting the branch ports and collecting data from the acquisition components in the symmetrical direction.

[0064] Based on the structural characteristics of the environmental chamber 1, the orientation of the heat engine's air outlet can be adjusted so that the outlet faces the four corners of the environmental chamber 1. For example, if four air outlets are provided, two are provided for each of the front and rear half-chambers. The two air outlets in the front half-chamber correspond to the middle of the left front edge and the middle of the right front edge of the environmental chamber 1, respectively, so that the working range of the two air outlets is located between the two collection units in the first collection component 3. For example, the working range of the air outlet corresponding to the middle of the left front edge is located between the collection unit in the upper left corner and the collection unit in the lower left corner. The two air outlets in the rear half-chamber correspond to the middle of the left rear edge and the middle of the right rear edge of the environmental chamber 1, respectively, so that the working range of the two air outlets is located between the two collection units in the second collection component 4. For example, the working range of the air outlet corresponding to the middle of the right rear edge is located between the collection unit in the upper right corner and the collection unit in the lower right corner. This optimizes the temperature collection effect and better reflects the average temperature of various parts of the chamber.
