The average pressure of the multiple pressure plates is compared with the set threshold to determine whether the folding force of the rearview mirror needs to be adjusted.

[0006] Further, the folding drive seat comprises a semi-enclosed frame, a positioning block and a clamping shaft; The positioning block is arranged on the lower supporting surface of the semi-enclosed frame, and the upper surface of the positioning block is provided with a contoured surface that fits the bottom of the rearview mirror; The clamping shaft is arranged above the semi-enclosed frame, and the end portion thereof extends into the semi-enclosed frame and is clamped with the contoured rearview mirror mounting frame.

[0007] Furthermore, it also includes a support sleeve coaxially arranged with the rotating shaft; The support sleeve is arranged on the second sliding seat, one end of the rotating shaft is fixed on the folding driving seat, and the other end is rotatably connected with the support sleeve through a bearing group.

[0008] Furthermore, the driving assembly includes a transmission seat, a screw nut group and a driving motor; The screw nut assembly is used to drive the transmission seat to move in a straight line; The transmission seat is fixedly connected to the first sliding seat by bolts, and an adjustment hole for the bolts to pass through is provided on the first sliding seat, and the adjustment hole is arranged along the first direction.

[0010] Furthermore, an angle sensor is arranged at one end of the rotating shaft away from the folding driving seat.

[0011] Furthermore, two groups of supporting components are provided between the folding drive seat and the second sliding seat; The two groups of support components are symmetrically arranged around the center of the rotating shaft, and include guide wheels and arc-shaped guide rails for guiding the guide wheels to roll around the rotating shaft.

[0012] Furthermore, a limiting protrusion is provided on the inner side of the support arm, and a limiting groove is provided on the slide groove corresponding to the limiting protrusion; The distance between the end surfaces of the two limiting protrusions is greater than the distance between the bottoms of the two limiting grooves.

[0013] Furthermore, the fixing frame includes two bases and a mounting seat mounted on the two bases; A calibration mounting block is provided on one side of the mounting seat, and a positioning pressing plate and a clamping arm are provided on one side of the calibration mounting block; A plurality of locking bolts are arranged on the other side of the mounting seat.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 10 The vehicle rearview mirror detection device shown in the figure comprises: a fixing frame 1, and a test assembly 2 arranged on one side of the fixing frame 1; the test assembly 2 comprises a folding drive seat 21, a second sliding seat 22, a first sliding seat 23 and a driving assembly 24 arranged in sequence from top to bottom, the driving assembly 24 is used to drive the first sliding seat 23 to slide along a first direction 2a, the second sliding seat 22 to slide along a second direction 2b perpendicular to the first direction 2a, and the folding drive seat 21 is rotatably arranged on the second sliding seat 22 via a rotating shaft 25; Two support arms 221 are provided at the bottom of the second sliding seat 22, two slide grooves 231 for the two support arms 221 to slide are provided above the first sliding seat 23, a needle row 26 is provided at the bottom of the support arms 221, and at least two spring plungers 27 and a plurality of pressure sheets 28 are provided on the side walls of the support arms 221 facing the slide grooves 231; During the test, the side wall of the slide groove 231 on one side of the first sliding seat 23 squeezes the multiple spring plungers 27 on the support arm 221 on the same side, so that the ball of the spring plunger 27 is compressed. At this time, the end of the spring plunger 27 is lower than the plane of the pressure plate 28, and the side wall of the slide groove 231 contacts the pressure plate 28, and the first sliding seat 23 is continuously driven until the rearview mirror starts to move initially, which is the maximum folding force required by the rearview mirror. At this time, the pressure of multiple pressure plates 28 is synchronously obtained, and the average pressure of multiple pressure plates 28 is obtained by calculation, and it is compared with the set threshold value to determine whether the folding force of the rearview mirror needs to be adjusted. It should be noted that the first direction 2a refers to the direction tangent to the circumference set by the folding radius of the rearview mirror, and is parallel to the mounting surface on the mounting frame of the rearview mirror, while the second direction 2b refers to the radial direction of the circumference when the rearview mirror is opened or folded, and is set perpendicular to the first direction 2a. In addition, the rearview mirror used in the test of the present invention is a semi-finished product, that is, the internal parts are not installed, and it is only a combination of a base and a mounting frame.

[0024] In the present invention, a fixing frame 1 is installed on a test platform, and the fixing frame 1 is used to support and install a rearview mirror to simulate the installation state of the rearview mirror; a first sliding seat 23, a second sliding seat 22, a folding drive seat 21 and a drive assembly 24 are installed on the test platform in sequence, the second sliding seat 22 is located at the bottom of a groove between two support arms 221 and does not contact the top surface of the first sliding seat 23, the second sliding seat 22 utilizes the needle rows 26 on the two support arms 221 to roll with the first sliding seat 23, the folding drive seat 21 is connected to the second sliding seat 22 via a rotating shaft 25, and the rearview mirror is positioned in the folding drive seat 21 by adjusting the rotation angle of the folding drive seat 21 and the sliding position of the second sliding seat 22.

[0025] The testing process of the present invention is as follows: in the initial state, the spring plungers 27 on both sides make the second sliding seat 22 float and support on the first sliding seat 23 along the first direction 2a, and the end of the spring plunger 27 protrudes from the pressure plate 28. At this time, the pressure plates 28 on both sides are not in contact with the side walls of the slide groove 231, so as to avoid the pressure plates 28 from contacting the side walls of the slide groove 231 in the initial position, thereby reducing unnecessary friction and wear; the driving assembly 24 is started to drive the first sliding seat 23 to slide, and the sliding of the first sliding seat 23 is realized by the guide rail and the slider; when the first sliding seat 23 slides, pressure is applied to the support arm 221 on one side of the second sliding seat 22, so that the multiple spring plungers 27 on the support arm 221 are squeezed until the end of the spring plunger 27 When flush with the force-bearing surface of the pressure plate 28, the side wall of the slide groove 231 abuts against multiple pressure plates 28, and the first sliding seat 23 and the second sliding seat 22 cooperate to make the folding drive seat 21 drive the rearview mirror to fold. When the folding starts, the controller records the pressure values ​​of multiple pressure plates 28, and calculates the average pressure value of multiple pressure plates 28, and compares the average pressure value with the set threshold value. The set threshold value includes a maximum set threshold value and a minimum set threshold value. When the average pressure value is greater than the maximum set threshold value, the folding force is too large, and the unlocking direction of the hinge shaft needs to be adjusted; when the average pressure value is less than the minimum set threshold value, the folding force is insufficient, and the locking direction of the locking shaft needs to be adjusted, thereby ensuring that the folding force of the rearview mirror meets the usage requirements.

[0026] The present invention realizes the automatic test of the folding force of the rearview mirror by setting the folding drive seat 21, the first sliding seat 23, the second sliding seat 22 and the driving assembly 24, completely replacing the traditional manual folding and unfolding operations, reducing labor intensity, and improving the test efficiency. The folding force can be measured in real time and accurately by setting the spring plunger 27 and the pressure plate 28, avoiding the subjectivity of manual testing and effectively ensuring the consistency of product quality. The folding force is evaluated by using the average pressure value of multiple pressure plates 28, which further improves the reliability and stability of the measurement data and ensures the high accuracy of the folding force measurement.

[0027] In the present invention, the folding drive seat 21 includes a semi-enclosed frame 211, a positioning block 212 and a clamping shaft 213; the positioning block 212 is arranged on the lower supporting surface of the semi-enclosed frame 211, and the upper surface of the positioning block 212 is provided with a contoured surface that fits with the bottom of the rearview mirror; the clamping shaft 213 is arranged above the semi-enclosed frame 211, and its end extends into the semi-enclosed frame 211, and is clamped to the rearview mirror mounting frame with the contoured surface.

[0028] Specifically, the folding drive seat 21 adopts a split design. When testing rearview mirrors of different models, it is only necessary to replace the appropriate positioning block 212 without replacing the entire folding drive seat 21, which reduces the equipment update and maintenance costs and improves the adaptability and flexibility of the folding drive seat 21. In another preferred embodiment, the positioning block 212 is located at the opening of the semi-enclosed frame 211, and a bar hole is provided on the positioning block 212, allowing the positioning block 212 to move within a certain range, and the position of the positioning block 212 relative to the inside of the semi-enclosed frame 211 can be adjusted so that the contoured surface better fits the bottom shape of the rearview mirror, ensuring the stability and reliability of the clamping. In addition, the clamping shaft 213 is driven in the vertical direction by a cylinder, and a rubber head is provided at the end of the clamping shaft 213 to avoid damage to the rearview mirror.

[0029] In a preferred embodiment, the testing device also includes a support sleeve 29 coaxially arranged with the rotating shaft 25; the support sleeve 29 is arranged on the second sliding seat 22, one end of the rotating shaft 25 is fixed on the folding drive seat 21, and the other end is rotatably connected to the support sleeve 29 through a bearing group 30.

[0030] Specifically, the bearing group 30 disposed in the support sleeve 29 is a combination of an end bearing and a deep groove ball bearing or a combination of multiple deep groove ball bearings, so that the rotating shaft 25 rotates smoothly and flexibly, further improving the stability and reliability of the movement of the folding drive seat 21; In addition, in the preferred structure, during the installation of the rearview mirror to the folding drive seat 21, the support sleeve 29 can be lifted upward, further raising the support surface of the folding drive seat 21, so that the rearview mirror can fit better in the folding drive seat 21, effectively ensuring the positioning accuracy of the rearview mirror. Preferably, the lifting of the support sleeve 29 can be driven by a gasket or a power structure.

[0031] In a preferred embodiment of the present invention, the driving assembly 24 includes a transmission seat 241, a screw nut group 242 and a driving motor 243; the screw nut group 242 is used to drive the transmission seat 241 to move in a straight line; the transmission seat 241 is fixedly connected to the first sliding seat 23 by bolts, and an adjustment hole 232 for the bolt to pass through is provided on the first sliding seat 23, and the adjustment hole 232 is arranged along the first direction 2a.

[0032] During the process of installing the rearview mirror to the folding drive seat 21, the multiple bolts connected to the transmission seat 241 are in an unlocked state. The folding drive seat 21 is rotated to a suitable angle position, and the folding drive seat 21 is manually pushed toward the rearview mirror. At this time, through the setting of the adjustment hole 232, the first sliding seat 23 and the second sliding seat 22 cooperate to clamp the rearview mirror. Through the separate setting of the first sliding seat 23 and the driving assembly 24, the first sliding seat 23 can slide autonomously along the first direction 2a to facilitate the adjustment of the initial test position of the second sliding seat 22.

[0033] On the basis of the above embodiments, in order to reduce the influence of manual operation errors on the test accuracy, the first sliding seat 23 is provided with a centering and correcting component on both sides along the second direction 2b; the centering and correcting component includes two adjusting cylinders 33 and a distance sensor, and the two adjusting cylinders 33 are arranged at the front end and the rear end of the support arm 221; the driving rod end of the adjusting cylinder 33 is provided with a ball for adjusting the distance between the support arm 221 and the side wall of the slide groove 231.

[0034] When testing the folding force, the driving rod of the adjusting cylinder 33 is in a retracted state, at which point only the spring plunger 27 is in contact with the side wall of the slide groove 231. After the folding force test is completed and before the folding angle test of the rearview mirror is performed, the two adjusting cylinders 33 adjust the extension distance of the driving rod according to the sensing signal of the distance sensor, and perform centering adjustment on the second sliding seat 22. After the centering adjustment is completed, the multiple bolts on the transmission seat 241 are manually tightened. At this point, the second sliding seat 22 is in a centering state along the second direction 2b. The adjusted ball and spring plunger 27 are in rolling contact with the side wall of the slide groove 231, while the pressure plate 28 is not in contact with the side wall of the slide groove 231. The driving assembly 24 drives the first sliding seat 23 to slide back and forth. Based on the change of the folding radius of the rearview mirror, the second sliding seat 22 will slide on the first sliding seat 23, so that the folding driving seat 21 drives the rearview mirror to fold or open.

[0035] During the folding or opening process, the folding drive seat 21 rotates around the hinge axis following the rearview mirror, and at the same time rotates around the rotation axis 25, so that the rotation angle of the folding drive seat 21 around the rotation axis 25 is equal to the folding angle of the rearview mirror driven by the folding drive seat 21. Therefore, in a preferred embodiment, an angle sensor 31 is set at the end of the rotation axis 25 away from the folding drive seat 21 to realize the testing of the folding angle.

[0036] Specifically, two protrusions are formed on the upper surface of the first sliding seat 23 facing the second sliding seat 22, and the outer sides of the two protrusions form the sliding groove 231. An avoidance groove is formed between the two protrusions. When the second sliding seat 22 slides on the first sliding seat 23, the avoidance groove can allow the angle sensor 31 to pass smoothly. Through the setting of the angle sensor 31, the rotation angle of the folding drive seat 21 can be measured in real time and accurately, providing high-precision angle feedback, thereby determining the folding position of the rearview mirror, and further being able to test the folding angle of the rearview mirror, directly obtaining the folding angle of the rearview mirror, so as to fully verify the folding performance of the rearview mirror.

[0037] In another preferred embodiment, in order to prevent the folding drive seat 21 from tilting when testing the rearview mirror, two groups of support components 32 are provided between the folding drive seat 21 and the second sliding seat 22; the two groups of support components 32 are symmetrically arranged around the center of the rotating shaft 25, including a guide wheel 321, and an arc-shaped guide rail 322 for guiding the guide wheel 321 to roll around the rotating shaft 25.

[0038] Specifically, in the present invention, the guide wheel 321 is fixed on the folding drive seat 21, and the arc-shaped guide rail 322 is fixed on the second drive seat. A V-shaped protrusion is provided on the outer ring surface of the guide rail, and a guide groove for the V-shaped protrusion to be embedded is provided in the circumferential direction of the guide roller. When the folding drive seat 21 rotates around the rotating shaft 25, the movement trajectory of the folding drive seat 21 is accurately guided by the cooperation of the guide wheel 321 and the arc-shaped guide rail 322 to ensure the accuracy of the folding angle; and the trajectory of the arc-shaped guide rail 322 can completely cover the maximum folding angle of the rearview mirror. During the folding angle test, the guide wheel 321 is always moved along the trajectory of the guide rail, which supports the folding drive seat 21 and ensures that the movement trajectory of the folding drive seat 21 is accurate, further improving the test accuracy of the folding angle.

[0039] In the present invention, when the folding drive seat 21 drives the rearview mirror to fold or open, the folding resistance of the rearview mirror will form a reaction force on the second sliding seat 22, causing the support arm 221 on one side of the second sliding seat 22 to be lifted, and the gap between the support arm 221 and the side wall of the slide groove 231 changes, making it difficult for the sensor sheet to contact the side wall of the slide groove 231, resulting in the inability to obtain the pressure value. Therefore, in order to solve this problem, the inner side edge of the support arm 221 is provided with a limiting protrusion 221a, and the slide groove 231 is provided with a limiting groove corresponding to the limiting protrusion 221a; when the support arm 221 is lifted by the reaction force, the limiting protrusion 221a will contact the upper surface of the limiting groove, thereby preventing the support arm 221 from further lifting, limiting the displacement of the second sliding seat 22 in the vertical direction, ensuring that it always remains on the predetermined path during the sliding process, and reducing the movement deviation. In addition, the distance between the end faces of the two limiting protrusions 221a is greater than the distance between the bottoms of the two limiting grooves. The limiting protrusion 221a is completely embedded in the limiting groove. At this time, there is still a gap between the limiting protrusion 221a and the limiting groove, so that the side wall of the slide groove 231 can fully abut against the multiple pressure plates 28 to ensure the accuracy of the folding force test.

[0040] In a preferred embodiment of the present invention, the fixing frame 1 includes two bases 11 and a mounting seat 12 mounted on the two bases 11; a calibration mounting block 13 is provided on one side of the mounting seat 12, and a positioning clamping plate 14 and a clamping arm 15 are provided on one side of the calibration mounting block 13, and a plurality of locking bolts 16 are provided on the other side of the mounting seat 12. The positioning clamping plate calibrates the base of the rearview mirror at a set position to reduce the debugging time, a plurality of the clamping arms 15 are provided, and the clamping arms 15 are hinged on the mounting seat 12, and the rearview mirror base is clamped by folding, and the locking bolts 16 lock the base from the other side, and the double clamping method ensures the stability of the rearview mirror base during the test.

[0041] The present invention also provides a vehicle rearview mirror detection method, which uses a vehicle rearview mirror detection device and includes the following steps: Install the rearview mirror on the folding drive seat 21 to ensure that the folding part of the rearview mirror is tightly matched with the folding drive seat 21; prevent the rearview mirror from loosening during the folding process and reduce the test error caused by improper installation.

[0042] Adjust the position of the second sliding seat 22 so that the pressure plates 28 on both sides do not contact the side walls of the slide groove 231, ensuring that the spring plungers 27 on both sides provide floating support for the second sliding seat 22; avoid contact between the pressure plate 28 and the side walls of the slide groove 231 in the initial position to reduce unnecessary friction and wear.

[0043] Start the driving assembly 24 to drive the first sliding seat 23 to move along the first direction 2a. The movement of the first sliding seat 23 will apply pressure to the support arm 221 on one side of the second sliding seat 22, so that the multiple spring plungers 27 on the support arm 221 are squeezed until the end of the spring plunger 27 is flush with the force-bearing surface of the pressure plate 28, and the side wall of the slide groove 231 abuts against the multiple pressure plates 28; by gradually applying pressure to simulate the folding force in actual use, the contact between the spring plunger 27 and the pressure plate 28 ensures the accuracy of pressure transmission, reduces the measurement error caused by poor contact, and further ensures the smoothness of the test process.

[0044] When the folding drive seat 21 drives the rearview mirror to start moving, the pressure values ​​of multiple pressure plates 28 are recorded, and the average pressure value of the multiple pressure plates 28 is obtained by calculation and compared with the set threshold value. If the average pressure value is greater than the maximum set threshold value, the folding force is too large and the unlocking direction of the hinge axis needs to be adjusted; if the average pressure value is less than the minimum set threshold value, the folding force is insufficient and the locking direction of the locking axis needs to be adjusted to ensure that the folding force of the rearview mirror meets the usage requirements.

[0045] Through the above optimized steps, the folding force of the rearview mirror can be effectively evaluated to ensure that it meets the design requirements and improve product quality and consistency.

[0046] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
