Description

Technical Field

[0001] This utility model relates to the field of rearview mirror technology, specifically to a car folding rearview mirror that is adjustable in three directions (XYZ) for experimental verification. Background Technology

[0002] As the automotive industry continues to evolve, consumers have increasingly higher expectations for vehicle performance. They demand not only excellent handling and flexible space adaptability in urban conditions, but also outstanding energy efficiency and driving stability at high speeds. However, given the relatively fixed body structure design of traditional automobiles, the rearview mirror, as a protruding component, has a significant impact on the overall vehicle's drag coefficient.

[0003] Traditional rearview mirrors typically employ a simple, fixed structure, offering only basic vision assistance. Furthermore, their adjustment functions are limited, mostly manual and restricted to a limited plane angle, making them unsuitable for complex and ever-changing driving scenarios. Secondly, during automotive R&D and testing, engineers struggle to accurately control the rearview mirror's posture and obtain reliable data when testing its performance under different conditions, such as simulating wind noise and airflow stability at high speeds, as the mirror's inflexible adjustment hinders product improvement.

[0004] To address the aforementioned issues, existing technologies provide a rearview mirror that can be adjusted in one or two directions. However, the adjustment method is mostly manual, limited to horizontal or vertical plane angle adjustments. In the automotive R&D and testing phase, relying solely on one-way or two-way adjustment of the rearview mirror makes it difficult to comprehensively verify the wind resistance when the rearview mirror is in different positions. Furthermore, when testing the wind resistance of rearview mirrors, in order to verify the impact of rearview mirrors on the vehicle's drag coefficient under different orientations, different rearview mirror schemes are usually used for testing. In this process, different rearview mirror schemes need to be changed to verify the vehicle's wind resistance. However, each time a different rearview mirror scheme is changed, it is necessary to consume manpower and resources to remake a new rearview mirror model, which not only increases the time for verifying the vehicle's wind resistance, but also the models made each time are not universally applicable, increasing cost waste. Utility Model Content

[0005] This invention provides a car folding rearview mirror that is adjustable in three directions (XYZ) for testing and verification, in order to solve the problem that the position of the rearview mirror is difficult to adjust, which makes it inconvenient to verify the vehicle's wind resistance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A car folding rearview mirror for experimental verification and adjustable in three XYZ directions includes: a first slider, a second slider, a third slider, a base, and a lens; the first slider is slidably mounted on the base and configured to slide along a first direction on the base; the second slider is slidably mounted on the first slider and configured to slide along a second direction on the first slider; a first through hole is formed on the first slider, a second through hole is formed on the second slider, and a third through hole is formed on the base; the third slider is slidably mounted on the second slider and is capable of sliding along a third direction through the first through hole, the second through hole, and the third through hole; the lens is detachably mounted on the third slider; the first direction, the second direction, and the third direction are perpendicular to each other.

[0008] Based on the aforementioned technical means, by setting a first slider, a second slider, and a third slider, the rearview mirror can be adjusted in three different directions. Since the first slider, the second slider, and the third slider are all independent components, these three sliders can adjust the rearview mirror independently, enabling rapid adjustment of the rearview mirror to different positions. This satisfies the need to verify the impact of the rearview mirror's position on the vehicle's wind resistance. Secondly, by adjusting the rearview mirror in three different directions, models of the rearview mirror in different positions can be simulated, reducing unnecessary manufacturing of rearview mirror orientation models and thus reducing cost waste. In addition, during the testing of the impact of different rearview mirror lens shapes on vehicle wind resistance, only the rearview mirror lens needs to be removed from the third slider to replace the rearview mirror lens, eliminating the need to disassemble the entire rearview mirror assembly. This facilitates the verification of the impact of different lens shapes on vehicle wind resistance and reduces the time required to replace the rearview mirror.

[0009] Furthermore, the base is provided with a first sliding groove, which is arranged along the first direction. The first sliding groove is adapted to the first slider, which is slidably mounted on the first sliding groove and can slide along the first direction on the first sliding groove.

[0010] According to the above technical means, in order to facilitate the sliding of the first slider on the base, a first groove adapted to the first slider is provided between the base and the first slider. The first groove can facilitate the sliding of the first slider on the base, and can also fix the first slider on the base, thereby limiting the first slider during the sliding process and preventing the first slider from sliding out of the area formed by the first groove.

[0011] Furthermore, a first scale is provided on the first groove, and the first scale is set along the first direction.

[0012] Based on the above technical means, in order to further determine the specific sliding length of the first slider, a scale with graduations is set between the first groove and the first slider, so that after sliding the first slider, it can be clearly determined how much distance the first slider has slid on the first groove (or can be considered as on the base). In the verification work of the rearview mirror, effective data can be obtained so as to record the range of the sliding distance of the first slider when the vehicle's wind resistance is reduced.

[0013] Furthermore, it also includes a first positioning pin; a plurality of first positioning holes are formed on the first slide groove, and the plurality of first positioning holes are equidistantly distributed along the first direction; a second positioning hole is formed on the first slider; the first positioning pin can pass through the first positioning hole and the second positioning hole to position the first slider on the first slide groove.

[0014] According to the above technical means, in order to fix the position of the first slider after it slides, so that the first slider can be used to verify the wind resistance of the vehicle after it is fixed, a first positioning pin is provided that can pass through the first positioning hole on the first slide groove and the second positioning hole on the first slider. This pin can fix the position of the first slider after it slides on the first slide groove.

[0015] Furthermore, the first slider is provided with a second slide groove, which is arranged along the second direction. The second slide groove is adapted to the second slider, and the second slider is slidably mounted on the second slide groove, and the second slider can slide along the second direction on the second slide groove.

[0016] According to the above technical means, in order to facilitate the sliding of the second slider on the first slider, a second slide groove adapted to the second slider is provided between the second slider and the first slider. The second slide groove can facilitate the sliding of the second slider on the first slider, and can also fix the second slider on the first slider, thereby limiting the second slider during the sliding process and preventing the second slider from sliding out of the area formed by the second slide groove.

[0017] Furthermore, a second scale is provided on the second slide, and the second scale is set along the second direction.

[0018] Based on the above technical means, in order to further determine the specific sliding length of the second slider, a scale with graduations is set between the second slide groove and the second slider, so that after sliding the second slider, it can be clearly determined how far the second slider has slid on the second slide groove. In the verification work of the rearview mirror, effective data can be obtained so as to record the range of sliding distance of the second slider when the vehicle's wind resistance is reduced.

[0019] Furthermore, it also includes a second positioning pin; a plurality of third positioning holes are formed on the second slide groove, and the plurality of third positioning holes are equidistantly distributed along the second direction; a fourth positioning hole is formed on the second slider; the second positioning pin can pass through the third positioning hole and the fourth positioning hole to position the second slider on the second slide groove.

[0020] According to the above technical means, in order to fix the position of the second slider after it slides, so that the second slider can be used to verify the vehicle's wind resistance after it is fixed, a second positioning pin is provided that can pass through the third positioning hole on the second slide groove and the fourth positioning hole on the second slider. This pin can fix the position of the second slider after it slides on the second slide groove.

[0021] Furthermore, a third scale is provided on the third slider, and the third scale is set along the third direction.

[0022] Based on the aforementioned technical means, in order to further determine the specific sliding length of the third slider, a scale with graduations is set on the third slider so that after sliding the third slider, it can be clearly determined how much distance the third slider has slid in the third direction. In the verification work of the rearview mirror, effective data can be obtained so as to record the range of sliding distance of the third slider when the vehicle's wind resistance is reduced.

[0023] Furthermore, it also includes a third positioning pin, a fifth positioning hole is formed on the third slider, the fifth positioning hole extends along the third direction, a sixth positioning hole is provided on the second slider, and the third positioning pin can pass through the fifth positioning hole and the sixth positioning hole to position the third slider on the second slider.

[0024] According to the above technical means, in order to fix the position of the third slider after it slides, so that the third slider can be used to verify the vehicle's wind resistance after it is fixed, a third positioning pin is set that can pass through the fifth positioning hole on the third slider and the sixth positioning hole on the second slider. This pin can fix the position of the third slider after it slides in the through hole.

[0025] Furthermore, it also includes a rotating connecting shaft and a fourth positioning pin. The third slider has a first connecting hole and a seventh positioning hole, and the lens has an eighth positioning hole and a second connecting hole. The seventh positioning hole extends in a fourth direction. The rotating connecting shaft can pass through the first connecting hole and the second connecting hole to rotatably mount the lens on the third slider. The lens is configured to rotate in a fourth direction. The fourth positioning pin can pass through the seventh positioning hole and the eighth positioning hole to position the lens on the third slider during rotation.

[0026] According to the aforementioned technical means, the lens is connected to the third slider via a rotating connecting shaft through a first connecting hole on the third slider and a second connecting hole on the lens. The lens can rotate around this rotating fixed shaft, and by setting the maximum rotation angle, the lens can be folded. Simultaneously, during the lens rotation process, to fix the lens's position and facilitate vehicle wind resistance verification after fixation, a fourth positioning pin passes through the seventh positioning hole on the third slider and the eighth positioning hole on the lens. When fixation is required, the fourth positioning pin is tightened.

[0027] The beneficial effects of this invention are as follows: By setting a first slider, a second slider, and a third slider, the rearview mirror can be adjusted in three different directions. Since the first slider, the second slider, and the third slider are all independent components, these three sliders can adjust the rearview mirror independently, enabling rapid adjustment of the rearview mirror to different positions, thereby satisfying the verification of the impact of the rearview mirror in different positions on vehicle wind resistance. Secondly, by adjusting the rearview mirror in three different directions, a model of the rearview mirror in different positions can be simulated, reducing unnecessary manufacturing of rearview mirror orientation models and thus reducing cost waste. In addition, during the testing of the impact of different rearview mirror lens shapes on vehicle wind resistance, it is only necessary to remove the rearview mirror lens from the third slider to replace the rearview mirror lens, without having to disassemble the entire rearview mirror device. This facilitates the verification of the impact of different lens shapes on vehicle wind resistance and reduces the time required to replace the rearview mirror. Attached Figure Description

[0050] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0051] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0052] In the embodiments of this application, 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 technical features indicated. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0053] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0054] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0055] This utility model provides a car folding rearview mirror that is adjustable in three XYZ directions for experimental verification, such as... Figure 1As shown, the system includes: a first slider 1, a second slider 2, a third slider 3, a base 4, and a lens 5. The first slider 1 is slidably mounted on the base 4 and is configured to slide along a first direction on the base 4, thus allowing the first slider 1 to move along the first direction on the base 4. The second slider 2 is slidably mounted on the first slider 1 and is configured to slide along a second direction on the first slider 1. A first through-hole 101 is formed on the first slider 1, a second through-hole 201 is formed on the second slider 2, and a third through-hole 401 is formed on the base 4. The through-hole areas of the first through-hole 101, the second through-hole 201, and the third through-hole 401 decrease sequentially. The third slider 3 is slidably mounted on the second slider 2, and the third slider 3 can slide along a third direction through the first through hole 101, the second through hole 201, and the third through hole 401. In this embodiment, the size of the through hole area of ​​the first through hole 101, the second through hole 201, and the third through hole 401 is not limited. For example, the area of ​​the third through hole 401 can be set to just accommodate the passage of the third slider. The lens 5 is detachably mounted on the third slider 3. The first direction, the second direction, and the third direction are perpendicular to each other.

[0056] It is worth noting that, in actual use, the base 4 can be embedded into the vehicle body. For example, when verifying the effect of the rearview mirror provided in this embodiment on the vehicle's wind resistance on a test vehicle, the base 4, which carries the first slider 1, the second slider 2, the third slider 3 and the lens 5, can be embedded into the vehicle body of the test vehicle, thereby reducing the overall volume of the rearview mirror exposed outside the vehicle body and reducing the vehicle's wind resistance during the test vehicle's operation.

[0057] By using the first slider 1 mounted on the base 4, the second slider 2 connected to the first slider 1 and all components connected to the second slider 2 can be treated as a whole. That is, the mirror body of the rearview mirror, except for the base, can slide on the base. When it is necessary to adjust the position of the rearview mirror, the position of the rearview mirror can be adjusted on the base 4 using the first slider 1, so as to verify the vehicle's wind resistance when the first slider 1 is slid to different positions. Of course, in this embodiment, the direction of sliding of the first slider 1 is not limited. In the following description, the first slider 1 slides in the X-axis direction (first direction), the second slider 2 slides in the Z-axis (second direction), and the third slider 3 slides in the Y-axis (third direction).

[0058] Therefore, in this embodiment, the components connected to the second slider 2 can be considered as a whole. This whole includes the crucial rearview mirror lens 5. By sliding this whole via the second slider 2, it can be moved along the Z-axis, and the position of the second slider 2 can be continuously adjusted to verify the vehicle's wind resistance at different sliding positions. Similarly, for the third slider 3 connecting the lens 5, the first through hole 101, the second through hole 201, and the third through hole 401 are precisely designed for the third slider 3 to pass through, facilitating its movement. The lens 5 can be slid along a direction perpendicular to the base 4 via the third slider 3. By sliding to different positions, the impact of different sliding lengths on the vehicle's wind resistance can be tested and verified.

[0059] In this embodiment, the above structure enables the rearview mirror to move in a first direction, a second direction, and a third direction. Specifically, when sliding in the first direction is required, the first slider 1 on the base 4 can be pushed along the first direction, causing the first slider 1 to slide on the base 4. Furthermore, the first slider 1 can slide back and forth on the base 4, repeatedly adjusting the rearview mirror's position in the first direction. Similarly, when sliding in the second direction is required, since the second slider 2 is slidably mounted on the first slider 1, pushing the second slider 2 along the second direction allows the second slider 2 to slide on the first slider 1. The second slider 2 can also slide back and forth on the first slider 1, repeatedly adjusting the rearview mirror's position in the second direction. Of course, when sliding in a third direction is required, the third slider 3, slidably mounted on the second slider 2, can be pushed to slide along a third direction passing through the first through hole 101, the second through hole 201, and the third through hole 401. The third slider 3 can also repeatedly slide back and forth within the first through hole 101, the second through hole 201, and the third through hole 401 to adjust the position in the third direction. It is worth noting that when the first slider 1, the second slider 2, and the third slider 3 slide, they not only slide themselves in the corresponding direction to adjust their orientation, but also drive the rearview mirror components they support to slide in the corresponding direction.

[0060] This embodiment, by setting a first slider, a second slider, and a third slider, allows the rearview mirror to be adjusted in three different directions. Since the first slider, the second slider, and the third slider are all independent components, these three sliders can adjust the rearview mirror independently, enabling rapid adjustment of the rearview mirror to different positions. This satisfies the requirement to verify the impact of the rearview mirror's position on vehicle wind resistance. Secondly, by adjusting the rearview mirror in three different directions, models of the rearview mirror in different positions can be simulated, reducing unnecessary manufacturing of rearview mirror orientation models and thus reducing cost waste. In addition, when testing the impact of different rearview mirror lens shapes on vehicle wind resistance, the rearview mirror lens only needs to be removed from the third slider to replace it, without disassembling the entire rearview mirror assembly. This facilitates the verification of the impact of different lens shapes on vehicle wind resistance and reduces the time required to replace the rearview mirror.

[0061] Preferably, the rearview mirror provided in this embodiment is as follows: Figure 2 As shown, a first sliding groove 6 is provided on the base 4. The first sliding groove 6 is arranged along a first direction, and the maximum length of the first sliding groove 6 can be aligned with the base 4. The first sliding groove 6 is adapted to the first slider 1, which facilitates the sliding of the first slider 1 on the base 4. Subsequently, the first slider 1 is slidably mounted on the first sliding groove 6, and the first slider 1 can slide along the first direction on the first sliding groove 6, and can also achieve the effect of the first slider 1 not sliding out of the area formed by the first sliding groove 6 during the sliding process.

[0062] Preferably, in order to further determine the specific sliding length of the first slider 1, the same applies... Figure 2 As shown, a first scale 601 can also be provided on the first slide groove to clearly indicate the exact distance that the first slider 1 has slid on the first slide groove 6 (or, as can be considered, on the base 4). This allows for the acquisition of effective data during the verification of the rearview mirror, facilitating the recording of the sliding distance range of the first slider 1 when the vehicle's wind resistance decreases. Furthermore, for ease of reading, the first scale 601 is set along a first direction.

[0063] To determine the specific sliding length of the first slider 1, a first ruler 601 can be mounted on the first slide groove 6, for example, by using four M6 screws. Alternatively, the first ruler 601 can be engraved on the first slide groove 6. This method further reduces the overall thickness and volume of the rearview mirror, thereby reducing vehicle wind resistance during aerodynamic testing. Therefore, this embodiment does not limit the way the first ruler 601 is positioned on the first slide groove 6; it can be set according to actual conditions.

[0064] It is worth noting that the first scale 601 can also be mounted on the base 4, for example, by using four M6 screws. The first slider 1 is mounted on the first scale 601. As the first slider 1 moves along the length of the base 4, the length of movement of the first slider 1 can be recorded using the first scale 601. This allows for a clear determination of the exact distance the first slider 1 slides on the base 4, providing effective data for verifying rearview mirrors, such as recording the range of sliding distances of the first slider 1 when vehicle wind resistance is reduced. Of course, in this method, the scale of the first scale 601 can also be engraved on the base 4, further reducing the overall thickness and volume of the rearview mirror, and further reducing vehicle wind resistance during wind resistance tests using this rearview mirror.

[0065] In this instruction manual, such as Figure 2 As shown in the bottom view, the first slider 1 can slide along the X-axis direction, i.e., the first direction. During the sliding process, the sliding distance of the first slider 1 can be determined by the first scale 601 on the first slide groove 6.

[0066] Preferred, also as Figure 2 As shown, the rearview mirror provided in this embodiment also includes a first positioning pin 7. Furthermore, a plurality of first positioning holes 602 are formed on the first sliding groove 6. These plurality of first positioning holes 602 are equidistantly distributed along a first direction. Of course, in this embodiment, the distribution of the plurality of first positioning holes 602 on the first sliding groove 6 is not limited; they can be equidistantly distributed, or, according to the needs of vehicle testing, a plurality of first positioning holes 602 adapted to the test plan can be pre-drilled. Simultaneously, a second positioning hole 102 is formed on the first slider 1. The first positioning pin 7 can pass through the first positioning hole 602 and the second positioning hole 102 to position the first slider 1 on the first sliding groove 6. After the first slider 1 slides on the first sliding groove 6, the position of the first slider 1 is fixed.

[0067] Preferably, to facilitate the sliding of the second slider 2 on the first slider 1, the first slider 1 provided in this embodiment is further provided with a second sliding groove 8. The second sliding groove 8 is arranged along a second direction and is adapted to the second slider 2. The second slider 2 is slidably mounted on the second sliding groove 8 and can slide along the second direction on the second sliding groove 8. The second sliding groove 8 can facilitate the sliding of the second slider 2 on the first slider 1, and can also fix the second slider 2 on the first slider 1, thereby limiting the second slider 2 during sliding and preventing it from sliding out of the area formed by the second sliding groove 8.

[0068] Preferably, to further determine the specific sliding length of the second slider 2, a second scale 801 is also provided on the second slide groove 8, wherein the second scale is set along a second direction. This allows for the determination of the specific distance the second slider 2 has slid along the second slide groove 8 after sliding the second slider 2, providing effective data for recording the sliding distance range of the second slider 2 when the vehicle's wind resistance is reduced, for example.

[0069] Preferred, such as Figure 3 As shown, after the second slider 2 slides, in order to fix the position of the second slider 2, the rearview mirror provided in this embodiment also includes a second positioning pin 9. A plurality of third positioning holes 802 are formed on the second slide groove 8, and the plurality of third positioning holes 802 are equidistantly distributed along the second direction. A fourth positioning hole 202 is formed on the second slider 2. The second positioning pin 9 can pass through the third positioning hole 802 and the fourth positioning hole 202 to position the second slider 2 on the second slide groove 8. Of course, in this embodiment, the distribution of the plurality of third positioning holes 802 on the second slide groove 8 is not limited; they can be equidistantly distributed, or, according to the needs of vehicle testing, a plurality of third positioning holes 802 adapted to the test plan can be pre-drilled.

[0070] In this instruction manual, such as Figure 3 As shown, the second slider 2 can slide along the Z-axis direction, i.e., the second direction. During the sliding process, the sliding distance of the second slider 2 can be determined by the second scale 801 on the second slide groove 8.

[0071] Preferably, in order to further determine the specific sliding length of the third slider 3, such as Figure 4 As shown, a third scale 301 is also provided on the third slider 3, which is set along the third direction. This allows the distance that the third slider 3 has slid in the third direction to be clearly determined after sliding the third slider 3. In the verification work of the rearview mirror, effective data can be obtained to record the range of sliding distance of the third slider 3 when the vehicle's wind resistance is reduced.

[0072] In this instruction manual, such as Figure 4 As shown, the second slider 2 can slide in the through hole along the Y-axis direction, i.e., the third direction. During the sliding process, the sliding distance of the third slider 3 can be determined by the third scale 301 on the third slider 3.

[0073] Preferred, such as Figure 5 and Figure 6As shown, the rearview mirror provided in this embodiment also includes a third positioning pin 10, a fifth positioning hole 302 is formed on the third slider 3, the fifth positioning hole 302 extends along the third direction, a sixth positioning hole 203 is provided on the second slider 2, and the third positioning pin 10 can pass through the fifth positioning hole 302 and the sixth positioning hole 203 to position the third slider 3 on the second slider.

[0074] Specifically, after the third slider 3 slides, in order to fix the third slider 3, the third positioning pin 10 can be inserted into the fifth positioning hole 302 through the sixth positioning hole 203 provided on the second slider 2. As the third positioning pin 10 is continuously screwed in, the friction between the third positioning pin 10 and the third slider 3 increases, and the third positioning pin 10 is connected to the second slider 2 through the sixth positioning hole 203. Therefore, with the help of the second slider 2 fixed on the first slider 1, the third positioning pin 10 is also fixed. So, as the friction between the third positioning pin 10 and the third slider 3 increases, the third slider 3 is fixed by the frictional force between the third positioning pin 10 and the third slider 3.

[0075] Preferred, such as Figure 7 and Figure 8 As shown, the rearview mirror provided in this embodiment also includes a rotating connecting shaft 11 and a fourth positioning pin 12. The third slider 3 is provided with a first connecting hole 303 and a seventh positioning hole 304, and the lens 5 is provided with an eighth positioning hole 501 and a second connecting hole 502. The seventh positioning hole 304 extends along a fourth direction. The rotating connecting shaft 11 can pass through the first connecting hole 303 and the second connecting hole 502 to connect the lens to the third slider 3. The fourth positioning pin 12 can pass through the seventh positioning hole 304 and the eighth positioning hole 501, positioning the lens 5 on the third slider during the rotation of the lens 5 around the rotating connecting shaft 11 in the fourth direction.

[0076] Specifically, lens 5 is provided with an eighth positioning hole 501 and a second connecting hole 502, while the third slider 3 is provided with a first connecting hole 303 and a seventh positioning hole 304. Through the second connecting hole 502 and the first connecting hole 303, a rotating connecting shaft 11 can connect lens 5 and the third slider 3 together. Furthermore, the selected rotating connecting shaft 11 does not firmly fix lens 5 to the third slider 3; lens 5 can rotate around the rotating connecting shaft 11. Depending on the set rotatable angle, lens 5 can be rotated to a corresponding angle. When the preset angle is reached, lens 5 can be brought into contact with the third slider 3, achieving the folding function of lens 5. Of course, Figure 8 The rotary connecting shaft 11 shown is only a schematic diagram. In actual testing, the rotary connecting shaft 11 can be set according to the actual situation.

[0077] In addition, as the lens 5 rotates around the rotating connecting shaft 11, the fourth positioning pin 12 can be passed through the seventh positioning hole 304 and the eighth positioning hole 501. As the fourth positioning pin is tightened, the friction that causes the lens 5 to rotate increases, thus fixing the lens 5 in place.

[0078] It is worth noting that the lens 5 can rotate around the rotating connecting shaft 11 by a certain angle, and the direction of rotation is the fourth direction. If the rotation angle of the lens 5 around the rotating connecting shaft 11 is set to 180 degrees, then the fourth direction is a semicircle with the length of the lens 5 as the radius and the connection point between the lens 5 and the third slider 3 as the center.

[0079] In addition, in this embodiment, the sliding distance of each slider can be recorded by the corresponding scale, the sliding position can be fixed by the corresponding positioning pin, and the accuracy of the sliding distance of each slider can be adjusted to 1mm. Of course, this embodiment does not limit this, and the accuracy range can be set according to the actual situation.

[0080] The rearview mirror structure provided in this embodiment allows for convenient adjustment of its position on the vehicle body, with independent adjustment in the X, Y, and Z directions. In vehicle aerodynamic performance testing, multiple rearview mirror-related schemes can be tested within a limited test time, significantly saving testing time and more efficiently verifying the impact of rearview mirrors in different positions and shapes on the overall vehicle aerodynamic performance. Furthermore, this structure is easy to assemble, disassemble, and adjust, reducing the workload of relevant personnel during testing. Besides its application in aerodynamic performance testing, it can also serve as a universal rearview mirror platform for various vehicle models; different models only require changing the mirror handle (third slider) or lens, thus saving on testing costs.

Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
