[0039] In the embodiments of the present application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of the features.
[0040] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.
[0041] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.
[0042] In the embodiments of the present application, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.
[0043] During the vehicle development process, if there are changes to the vehicle's interior, dashboard, air-conditioning ducts, air outlets and other components, the performance of the air-conditioning will be affected and changed, and experiments will be needed to verify whether its performance meets the requirements.
[0044] In the past, to verify the performance of air conditioners, a real vehicle modification method was used for real vehicle evaluation. This method required first removing the original vehicle parts and then installing the newly developed parts into the original vehicle for testing.
[0045] Vehicle disassembly and reassembly takes a long time and can cause irreversible damage to the original vehicle, increasing both time and production costs. During vehicle disassembly and reassembly, working space is limited, and the complex structures of some parts make operation difficult, potentially posing a risk of operator injury. Furthermore, the structure and shape of newly developed parts differ from those of the original, potentially interfering with the original vehicle during reassembly, making installation accuracy difficult to guarantee.
[0046] Based on this, an embodiment of the present application provides a test bench that can simulate the actual state of the cabin through different modular structures, thereby testing and verifying the performance of the air conditioner. In this way, the test bench can eliminate the process of disassembling and reinstalling the vehicle, quickly confirm the vehicle's air conditioning performance, and save production costs.
[0047] For details, please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a test bench 100 provided in an embodiment of the present application. The test bench 100 includes a supporting platform 1, a first door panel structure 2, and a second door panel structure 3. The first door panel structure 2 and the second door panel structure 3 are arranged on the supporting platform 1 at intervals along a first direction, wherein the first direction is parallel to the supporting platform 1.
[0048] The supporting platform 1 can simulate the floor of the vehicle's cabin, the first door panel structure 2 and the second door panel structure 3 can simulate the two side door panels of the vehicle, and the first door panel structure 2 and the second door panel structure 3 can also be used to connect the vehicle's dashboard and roof.
[0049] In this way, the supporting platform 1, the first door panel structure 2, the second door panel structure 3, and the instrument panel and top panel connected thereto can enclose a simulated driving space, providing an environment close to the actual vehicle usage scenario for related tests.
[0050] The installation positions of the first door panel structure 2 and the second door panel structure 3 on the supporting platform 1 are adjustable to adjust the volume of the simulated driving space. In this way, the positions of the first door panel structure 2 and the second door panel structure 3 can be adjusted according to the width and volume of the test vehicle model, so that the simulation environment of the test bench 100 fits the actual vehicle model and the test structure is more accurate.
[0051] In addition, the test bench 100 may further include an air-conditioning support frame 4 , which is used to support an air conditioner. The air-conditioning support frame 4 is connected to the supporting platform 1 , and its position on the supporting platform 1 is adjustable.
[0052] Since the installation positions of air conditioners in vehicle cabins of different models vary, the position of the air conditioner support frame 4 on the carrying platform 1 is adjustable, which allows the test bench 100 to flexibly adapt to various air conditioner layout requirements. There is no need to disassemble or redesign the test bench 100 due to different air conditioner positions, thereby improving the flexibility and versatility of the test bench 100.
[0053] When testing the air conditioning performance of different vehicle models, the test bench 100 only needs to adjust the positions of different components on the support platform 1 to simulate the operating environment of a newly developed vehicle model. This eliminates the need for vehicle modification or reinstallation, simplifying assembly and reducing operational difficulty, time and labor costs, and improving work efficiency. Furthermore, the test bench 100 allows for component adjustments to accommodate various vehicle models, making it reusable for testing multiple vehicle models, thereby reducing development costs.
[0054] At the same time, the positions of the first door panel structure 2 and the second door panel structure 3 relative to the supporting platform 1 can be adjusted, and the volume of the simulated driving space can be adjusted. In this way, not only can simulation experiments be conducted on small cars, but it can also be suitable for the development and testing of compact, medium and large cars, sports utility vehicles (SUVs) and multi-purpose vehicles (MPVs), which can improve the versatility of the test bench 100.
[0055] Please refer to Figure 1 and Figure 2 , Figure 2 for Figure 1 As shown in the structural schematic diagram of the supporting platform 1, in some embodiments, the supporting platform 1 is provided with a plurality of first connection holes 11, and the plurality of first connection holes 11 are distributed in a square array, and the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4 are respectively connected to different first connection holes 11 to adjust the connection positions of the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4 on the supporting platform 1.
[0056] In this way, the first connection holes 11 distributed in a square array can provide a variety of position options for the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4, so as to adjust the position of each component according to different vehicle models, thereby improving the flexibility and versatility of the test bench 100.
[0057] In addition, multiple connection holes are provided to facilitate the connection of different components to the carrier platform 1, without the need to punch holes again according to the positions of different components, which can make the assembly process simpler and more convenient and save testing costs.
[0058] In some embodiments, a plurality of first scale lines 12 and a plurality of second scale lines 13 may be provided on the supporting platform 1, and the plurality of first scale lines 12 extend along the first direction and are spaced apart along the second direction, and are used as a reference for adjusting the position of the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4 on the supporting platform 1 along the second direction, where the second direction is perpendicular to the first direction and parallel to the supporting platform 1; the plurality of second scale lines 13 extend along the second direction and are spaced apart along the first direction, and are used as a reference for adjusting the position of the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4 on the supporting platform 1 along the first direction.
[0059] In this way, the operator can quickly measure and determine the position of the component in the first direction and the second direction based on the first scale line 12 and the second scale line 13, and the assembly and adjustment operations are more intuitive and simple, thereby reducing the assembly difficulty and cost, improving the test efficiency, and the accuracy and reliability of the test bench 100.
[0060] In some embodiments, a plurality of first scale lines 12 and a plurality of second scale lines 13 are intersected to form a plurality of grids distributed in a square array, and each grid is provided with at least one first connection hole 11 .
[0061] The first scale line 12 and the second scale line 13 intersect to form a square array of grids, each grid being provided with at least one first connecting hole 11. In this way, the grid can provide coordinate positioning for the first connecting hole 11, so that the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4 and other components have precise positioning references, thereby reducing errors during the installation process, thereby improving the accuracy and stability of the test bench 100.
[0062] When the operator installs the first door panel structure 2, the second door panel structure 3 and the air-conditioning support frame 4, the components can be connected to the first connection holes 11 in the corresponding grid according to the installation position and size of the components, which reduces the measurement and calibration process and thus improves assembly efficiency.
[0063] For example, the intervals between the plurality of first scale lines 12 along the second direction are 100 mm, and the intervals between the plurality of second scale lines 13 along the first direction are 100 mm, so that the first scale lines 12 and the second scale lines 13 can form a 100 mm*100 mm grid.
[0064] A first connecting hole 11 is provided at the center point of each square, and the distance between the first connecting hole 11 and the two adjacent first scale lines 12 and the two adjacent second scale lines 13 is 50 mm. In this way, when the first door panel structure 2, the second door panel structure 3 and the air-conditioning support 52 are connected to the supporting platform 1 through the first connecting hole 11, the size and distance of different components on the supporting platform 1 can be quickly determined, thereby improving the efficiency and accuracy of assembly.
[0065] Please continue to refer to Figure 1 In some embodiments, the first door panel structure 2 may include a first door panel body 21 and a first support arm 22 connected to the first door panel body 21; the second door panel structure 3 may include a second door panel body 31 and a second support arm 32 connected to the second door panel body 31. The position of the first support arm 22 on the first door panel is adjustable, and the position of the second support arm 32 on the second door panel is adjustable, so that the first support arm 22 and the second support arm 32 can support instrument panels of different heights and lengths.
[0066] Since the dashboards of different vehicle models may differ in height and length, the first support arm 22 and the second support arm 32 are used to connect the vehicle's dashboard. By making the positions of the first support arm 22 and the second support arm 32 adjustable on the door panel body, the test bench 100 can be flexibly adapted to dashboards of various specifications without the need to customize special door panel structures for different dashboards, thereby improving the versatility and adaptability of the test bench 100.
[0067] Specifically, the height, length and width of the instrument panel can be based on the height, length and width of the vehicle where the instrument panel is located, so that the first door panel structure 2, the second door panel structure 3 and the instrument panel can form a cabin space that matches the test vehicle model.
[0068] In some embodiments, the first support arm 22 may be provided in plurality, and the plurality of first support arms 22 are arranged along the first direction. The second support arm 22 may also be provided in plurality, and the plurality of second support arms 32 are also arranged along the first direction.
[0069] In this way, the plurality of first support arms 22 and the second support arms 32 can all support and connect the instrument panel, thereby making the connection of the instrument panel more stable, thereby improving the stability and reliability of the test bench 100 .
[0070] In some embodiments, the first door panel body 21 is provided with a plurality of second connection holes 211, and the plurality of second connection holes 211 are distributed in a square array. The first support arm 22 is connected to different second connection holes 211 to adjust the connection position of the first support arm 22 in the second direction and / or height direction on the first door panel body 21. The second direction is perpendicular to the first direction and parallel to the supporting platform 1.
[0071] In this way, the position of the first support arm 22 can be flexibly adjusted so that it can accurately adapt to dashboards of different heights and widths, meet the testing requirements of a variety of different vehicle models, and improve the versatility of the test bench 100.
[0072] Multiple second connection holes 211 are arranged in a square array, which can provide precise positioning points for the first support arm 22. The operator can accurately connect the first support arm 22 to the second connection hole 211 at the corresponding position according to the actual size and installation requirements of the instrument panel to ensure installation accuracy.
[0073] In some embodiments, the second door panel body 31 is provided with a plurality of second connection holes 211 , the plurality of second connection holes 211 are distributed in a square array, and the second support arms 32 are connected to different second connection holes 211 .
[0074] In some embodiments, scale lines spaced along the first direction and the second direction may also be provided on the first door panel body 21 and the second door panel body 31 to form a plurality of squares distributed in a square array, and each square is provided with at least one second connection hole 211 .
[0075] Please refer to Figure 1 and Figure 3 , Figure 3 for Figure 1 As shown in the structural schematic diagram of the first support arm 22, in some embodiments, the first support arm 22 may include a fixed section 221 and a telescopic section 222, the fixed end is connected to the first door panel body 21, the telescopic section 222 is connected to the fixed section 221, and can move relative to the fixed section 221 along the arrangement direction of the first door panel structure 2 and the second door panel structure 3 to support dashboards of different widths.
[0076] Since the positions of the first door panel structure 2 and the second door panel structure 3 determine the width of the vehicle cabin, if there is a difference between the width of the instrument panel and the width of the vehicle cabin, the fixed section 221 and the telescopic section 222 of the first support arm 22 can be flexibly adjusted to adapt to the size of the instrument panel, thereby improving the adaptability of the test bench 100.
[0077] The retractable first support arm 22 can reduce the need for customized components, lower production costs, and improve testing efficiency.
[0078] In some embodiments, the telescopic section 222 is provided with a plurality of third connection holes 224 along the first direction. The instrument panel can be connected to different third connection holes 224 according to the width of the instrument panel. In this way, the adaptability range of the instrument panel along the width direction can be further improved, thereby further improving the adaptability of the test bench 100.
[0079] In some embodiments, a bending portion 223 is provided at one end of the first support arm 22 away from the first door panel structure 2. Along the height direction, the bending portion 223 is bent in a direction away from the supporting platform 1. In this way, the instrument panel can be further positioned and the stability of the instrument panel can be improved.
[0080] In some embodiments of the present application, the second support arm 32 may have the same structure as the first support arm 22 in any of the above embodiments, and will not be described in detail here.
[0081] In some embodiments, the first door panel structure 2 may further include a first positioning pin 23 . The first positioning pin 23 is connected to the upper end of the first door panel body 21 and is used for cooperating with the top panel for positioning.
[0082] Through the precise cooperation of the first positioning pin 23, the position deviation between the first door panel structure 2 and the top panel during installation can be effectively reduced, thereby avoiding test errors caused by improper installation and improving the reliability of the test results.
[0083] In some embodiments, the first positioning pin 23 can be set to multiple, and the multiple first positioning pins 23 are arranged at intervals along the second direction, and the multiple first positioning pins 23 can all cooperate with the top plate for positioning. In this way, the accuracy and stability of the connection between the top plate and the first door panel structure 2 can be further improved, thereby improving the reliability of the test bench 100.
[0084] In some embodiments, the second door panel structure 3 may further include a second positioning pin 33 . The second positioning pin 33 is connected to the upper end of the second door panel body 31 and is used for cooperating with the top panel for positioning.
[0085] Through the precise cooperation of the second positioning pins 33, the position deviation between the second door panel structure 3 and the top plate during installation can be reduced, thereby avoiding test errors caused by improper installation and improving the reliability of the test results.
[0086] In some embodiments, the second positioning pin 33 can also be set to multiple, and the multiple second positioning pins 33 are arranged at intervals along the second direction, and the multiple second positioning pins 33 can all cooperate with the top plate for positioning. In this way, the accuracy and stability of the connection between the top plate and the second door panel structure 3 can be further improved, thereby improving the reliability of the test bench 100.
[0087] Please refer to Figure 1 and Figure 4 , Figure 4 for Figure 1As shown in the structural schematic diagram of the air-conditioning support frame 4, in some embodiments, the air-conditioning support frame 4 may include a support base 41 and a support platform structure 42, the support base 41 is fixed to the supporting platform 1, the support platform structure 42 is used to support the air conditioner, and the support platform structure 42 is connected to the support base 41 and can move in the height direction relative to the support base 41.
[0088] The installation position of the air conditioner may be different in different vehicle models or test scenarios. The support platform structure 42 can move in the height direction relative to the support base 41, so that the air conditioner support frame 4 can flexibly adapt to the installation height requirements of different air conditioners without the need to customize support frames of different heights, thereby improving the versatility and flexibility of the air conditioner support frame 4.
[0089] During the test process, if the height of the air conditioner needs to be adjusted to optimize the test effect or meet specific test conditions, the operator can easily achieve it by adjusting the support platform structure 42 without the need for complicated disassembly and reinstallation processes, thereby improving test efficiency.
[0090] In some embodiments, the support platform structure 42 may include a first support platform 421, a second support platform 422 and a third support platform 423. The first support platform 421 is transmission-connected to the support base 41. The second support platform 422 is connected to the first support platform 421 and can move along a first direction relative to the second support platform 422. The third support platform 423 is connected to the second support platform 422 and can move along a second direction relative to the second support platform 422. The second direction is perpendicular to the first direction and parallel to the supporting platform 1.
[0091] In this way, through the first support platform 421, the second support platform 422 and the third support platform 423, the air conditioner can be adjusted along the first direction, the second direction and the height direction respectively, so that the air conditioner support frame 4 can accurately adapt to the installation position requirements of the air conditioner under different vehicle models and different test scenarios, thereby improving the versatility and adaptability of the air conditioner support frame 4.
[0092] In addition, since the air-conditioning support frame 4 can also be connected to different first connection holes 11 on the supporting platform 1, the simulated position of the air conditioner can be made more accurate by adjusting the first connection hole 11, as well as the first support platform 421, the second support platform 422 and the third support platform 423, thereby improving the accuracy of the test results.
[0093] In some embodiments, the first support platform 421 may include a first support panel and a first power structure. The first support panel can be adjusted in height relative to the support base 41 through the first power structure.

[0111] In addition, since the seat support frame 5 can also be connected to different first connecting holes 11 on the supporting platform 1, the simulated position of the seat can be made more precise by adjusting the first connecting hole 11, as well as the guide rail structure 51, the support member 52 and the supporting member 53, thereby improving the accuracy of the test results.

[0122] In some embodiments, a roller 14 is provided on the side of the supporting platform 1 facing the ground. Through the provision of the roller 14, the test bench 100 can be easily moved to the vicinity of tooling equipment such as air conditioners and seats, so that the test bench 100 can be conveniently assembled with components such as air conditioners and seats, thereby improving assembly efficiency.
[0123] In addition, the test bench 100 is movable and can be moved to different working environments to simulate vehicle conditions in different working environments, making the test results more realistic and accurate.

[0126] Then, through the coordination of the guide rail structure 51, support member 52, and bearing member 53, the assembled seat can meet the vehicle's seating position requirements. The first, second, and third power structures are used to adjust the distance between the air conditioner support frame 4 and the seat position, ensuring that the assembled air conditioner meets the vehicle's required air conditioning position. The seat, air conditioner, and air conditioning ducts are then assembled onto the corresponding seat support frame 5 and air conditioner support frame 4.
[0127] Afterwards, the instrument panel is mounted on the first support arm 22 and the second support arm 32. The steering wheel is mounted on the steering wheel support frame 6.
