Abstract
Description
Technical Field
[0001] This utility model belongs to the field of durability testing technology, and specifically relates to a durability testing device for automotive sun visors. Background Technology
[0002] Most automotive interior parts are irregularly shaped components, consisting of numerous parts and made of relatively soft materials, such as sun visors on cars, vans, buses, and trucks. Sun visors are designed to prevent sunlight from entering the vehicle. They effectively cool the windshield and rear window area, especially in summer, reducing the heat inside the car and protecting the dashboard.
[0003] During the design phase, sun visors typically undergo durability testing to verify that their rotation opening can withstand a certain number of rotations. Existing automotive sun visors come in various types, such as those connected to the vehicle via a single L-shaped axis, allowing rotation along both the vertical and horizontal axes, or those connected via a horizontal axis that can only rotate vertically. Therefore, different types and sizes of sun visors require specialized testing equipment, resulting in high costs. Furthermore, testing sun visors with a single L-shaped axis necessitates the use of two drive components (X-axis and Y-axis) to rotate the visor along different axes, further increasing testing costs. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a vehicle sun visor durability testing device, which aims to solve the problem of the lack of a highly versatile and low-cost vehicle sun visor durability testing device in the prior art.
[0005] The automobile sun visor durability testing device proposed in this utility model includes a fixed base, a fixing component disposed on one side of the fixed base, and a driving component disposed on the fixed base adjacent to the fixing component. The driving component includes a driving part disposed on the fixed base, a lifting part disposed on the driving part, and a clamping part disposed on the lifting part. The fixing component is used to fix the rotating shaft of the sun visor to be tested. The driving part is used to adjust the distance between the clamping part and the fixing component. The lifting part drives the clamping part to move up and down, so that the clamping part drives the sun visor to be tested to rotate around the rotating shaft.
[0006] The aforementioned automotive sun visor durability testing device clamps the shaft to be tested for rotation using a fixed clamping mechanism. A drive component adjusts the distance between the clamping and fixing components, allowing for adjustments based on the different rotation shafts and the varying positions and orientations of the sun visor. The clamping component holds the end of the sun visor furthest from the rotation shaft, and a lifting component moves the clamping component up and down, allowing the upper and lower clamping parts to respectively push the sun visor upwards or downwards, thus achieving the sun visor durability test. After testing the shaft, the device re-fixes and adjusts the position of the clamping component for the shaft to be tested. This allows the device to test sun visors of different types and sizes, and a single lifting component can drive tests on two shafts in different directions, reducing the cost of the automotive sun visor durability testing device. Therefore, this invention solves the problem of the lack of a highly versatile and low-cost automotive sun visor durability testing device in the prior art.

[0027]
[0028] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation
[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.
[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] Please see Figures 1 to 8 The image shows a car sun visor durability testing device according to an embodiment of the present invention, including a fixed base 10, a fixing component 20 disposed on one side of the fixed base 10, and a driving component 30 disposed on the fixed base 10 adjacent to the fixing component 20, wherein:
[0033] The drive assembly 30 includes a drive component 31 mounted on the fixed base 10, a lifting component 32 mounted on the drive component 31, and a clamping component 33 mounted on the lifting component 32. The fixed assembly 20 is used to fix the rotating shaft of the sun visor to be tested. The drive component 31 is used to adjust the distance between the clamping component 33 and the fixed assembly 20. The lifting component 32 drives the clamping component 33 to move up and down, so that the clamping component 33 drives the sun visor to be tested to rotate around the rotating shaft.
[0034] Understandably, by setting a fixed clamp for the shaft to be rotated and then adjusting the distance between the clamping component 33 and the fixing component 20 via the drive component 31, adjustments can be made according to the different rotation shafts being tested and the different positions and postures of the sun visor. The clamping component 33 holds the end of the sun visor away from the rotation shaft, and the lifting component 32 drives the clamping component 33 to move up and down, so that the upper and lower clamping parts of the clamping component 33 are used to push the sun visor to rotate upwards or downwards, thereby achieving the durability test of the sun visor. After testing the shaft, the clamping component 33 is re-fixed and its position adjusted according to the shaft to be tested. This allows the automotive sun visor durability testing device to test sun visors of different types and sizes, and a single lifting component 32 can drive the testing of two shafts in different directions, reducing the cost of the automotive sun visor durability testing device. Therefore, this utility model solves the problem of the lack of a highly versatile and low-cost automotive sun visor durability testing device in the prior art.
[0035] It should be noted that the lifting component can be any existing lifting platform, telescopic cylinder, or other device or equipment. Since the specific structure of the lifting component is not the main point of protection in this solution, any structure or device that can drive the clamping component to lift is acceptable. Therefore, it will not be elaborated on here.
[0036] Specifically, the driving component 31 includes a first guide block 311 and a first slider 312 disposed on the fixed base 10. The first slider 312 has a groove 313 adapted to the first guide block 311, and the lifting component 32 is disposed on the first slider 312. By setting the cooperation of the guide block and the slider, the driving component 30 can slide on the fixed base 10, thereby adjusting the distance between the clamping component 33 and the fixed component 20. In addition, in specific implementation, the driving component 30 can be manually pushed to slide, and the fastener 26 can be used to fix the driving component 30 after sliding to a preset position to ensure the stable operation of the driving component 30. Moreover, by manually pushing the driving component 30, the additional power device is avoided, reducing the cost of the automotive sun visor durability testing device.
[0037] Additionally, the fixing assembly 20 includes a mounting bracket 21 mounted on the fixing base 10, a second guide block 22 and a second slider 23 mounted on the mounting bracket 21, and a fixed plate 24 and a movable plate 25 mounted on the second slider 23. The second slider 23 has a groove 313 adapted to the second guide block 22. Both the movable plate 25 and the fixed plate 24 have semi-circular holes 241. The two semi-circular holes 241 cooperate to form a clamping space for fixing the rotating shaft. The movable plate 25 is fixed to the second slider 23 by fasteners 26, so that the distance between the movable plate 25 and the fixed plate 24 is adjustable. In specific implementation, by adjusting the distance between the fixed plate 24 and the movable plate 25, the fixing assembly 20 can clamp and fix the rotating shaft of different sun visors to be tested. In addition, in specific implementation, a wear-resistant layer can also be provided between the two semi-circular holes 241 to reduce the friction loss between the semi-circular holes 241 and the rotating shaft during rotational durability testing, thereby improving the service life of the automotive sun visor durability testing device.
[0038] Specifically, the cross-sectional shape of the first guide block 311 and the second guide block 22 is T-shaped, or the cross-sectional area of the first guide block 311 and the second guide block 22 gradually decreases from one side near the groove 313 to the other side. In specific implementation, by adjusting the cross-sectional shape of the first guide block 311 and the second guide block 22, the first guide block 311 and the second guide block 22 will not fall out of the groove 313, but can only move along the length direction of the groove 313, so that the first guide block 311 and the second guide block 22 can move stably.
[0039] Additionally, the movable plate 25 has a first elongated hole 251, and the second slider 23 has a mounting hole 231 that matches the first elongated hole 251. A fastener 26 passes through the first elongated hole 251 and engages with the mounting hole 231, allowing the distance between the movable plate 25 and the fixed plate 24 to be adjustable. In practice, by providing the first elongated hole 251, the movable plate 25 adjusts the distance between itself and the fixed plate 24. After the distance adjustment is complete, the fastener 26 secures the movable plate 25 to the second slider 23.
[0040] Specifically, the mounting hole 231 penetrates the second slider 23, and the mounting hole 231 has a pin hole on the side near the mounting bracket 21 and a screw hole on the other side. The fastener 26 includes a top 261, a screw portion 262 adapted to the screw hole, and an elastic portion 263 disposed below the screw portion 262. When the top 261 abuts against the movable plate 25, the elastic portion 263 is deformed by the mounting bracket 21. In actual use, by providing the through mounting hole 231 and the elastic portion 263 at the bottom of the fastener 26, when the second slider 23 moves to the preset position, tightening the fastener 26, thereby using the compressive force of the elastic portion 263, fixes the second slider 23 to the preset position of the second guide block 22.
[0041] Additionally, the clamping component 33 includes a horizontal plate 331 connected to the lifting component, a vertical plate 332 disposed on the horizontal plate 331, and an L-shaped plate 333. The vertical portion of the L-shaped plate 333 and the vertical plate 332 are provided with multiple cooperating second elongated holes 334. Screws pass through the second elongated holes 334 and engage with nuts, allowing the distance between the horizontal portion of the L-shaped plate 333 and the horizontal plate 331 to be adjustable. The horizontal plate 331 and the horizontal portion cooperate to drive the sun shade under test to rotate around the axis of rotation under the action of the lifting component 32. The second elongated holes 334 allow for adjustable distance between the L-shaped plate 333 and the horizontal plate 331, thus achieving the clamping function. In practical use, the L-shaped plate 333 and the horizontal plate 331 are respectively disposed on the upper and lower sides of the sun shade under test. The up-and-down movement of the lifting component drives the sun shade under test to rotate around the axis of rotation, thereby achieving durability testing. It should be noted that the L-shaped plate 333 and the horizontal plate 331 do not clamp the sunshade under test tightly, but rather clamp the sunshade under test in the middle, and move the sunshade under test through contact to prevent the sunshade under test from detaching from the two, so as to ensure that the sunshade under test can be rotated normally for durability testing.
[0042] Specifically, the mounting bracket 21 is equipped with multiple second sliders 23. By setting multiple second sliders 23, sun visors of different sizes can be clamped and fixed using the movable plates 25 and fixed plates 24 on the multiple second sliders 23. This allows the automotive sun visor durability testing device to be adapted to various specifications and types of sun visors with a single device, improving versatility and reducing testing costs.
[0043] Additionally, the mounting bracket 21 includes a support plate 211 and a mounting plate 212 disposed on the support plate 211, with a second guide block 22 disposed on the mounting plate 212. By setting the support plate 211, the mounting plate 212 is suspended on the fixing base 10, thereby ensuring that the fixing assembly 20 is at a certain height and has sufficient space to fix sunshades of different specifications.
[0044] Specifically, a buffer layer is provided on both the L-shaped plate 333 and the opposite side of the horizontal section. The buffer layer can be made of elastic, wear-resistant materials such as nylon, rubber, and sponge to prevent damage to the sun visor and clamping component 33 during durability testing. This allows the sun visor to remain usable after testing and increases the lifespan of the automotive sun visor durability testing device, thereby indirectly reducing costs.
[0045] Specifically, such as Figures 6 to 7 The diagram illustrates the use of an L-shaped sun visor during durability testing. Different rotating shafts are fixed to the fixing assembly 20, and the position of the driving assembly 30 is adjusted to drive the L-shaped sun visor to rotate along these shafts for durability testing. Figure 8 The diagram shown illustrates the use of a single horizontal axis sunshade during durability testing. By fixing multiple exposed pivots of the single horizontal axis sunshade between different movable plates 25 and fixed plates 24, and then adjusting the position of the drive assembly 30, the single horizontal axis sunshade is driven to rotate along different pivots to conduct the durability test.
[0046] In summary, the automotive sun visor durability testing device in the above embodiments of this utility model clamps the shaft to be rotated for testing by setting a fixed clamp, and then adjusts the distance between the clamping component 33 and the fixing component 20 by the driving component 31. This allows for corresponding adjustments based on the different rotation shafts being tested and the different positions and postures of the sun visor. The clamping component 33 holds the end of the sun visor away from the rotation shaft, and the lifting component 32 drives the clamping component 33 to move up and down, so that the upper and lower clamping parts of the clamping component 33 are used to push the sun visor to rotate upward or downward, thereby realizing the durability test of the sun visor. After testing the rotation shaft, the clamping component 33 is re-fixed and the position of the clamping component 33 is adjusted according to the rotation shaft to be tested. This allows the automotive sun visor durability testing device to test sun visors of different types and sizes, and the testing of two shafts in different directions can be driven by a single lifting component 32, reducing the cost of the automotive sun visor durability testing device. Therefore, this invention solves the problem of the lack of a universal and low-cost automotive sun visor durability testing device in the prior art.
