Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a sun visor flipping durability test fixture. Background Technology

[0002] The primary function of a car sun visor is to shield the driver and passengers from direct sunlight and prevent glare. The rotational durability of the sun visor determines its lifespan. If the sun visor fails to rotate properly, it may wobble, sag, or detach, obstructing the driver's view and affecting driving safety. Therefore, it is necessary to conduct rotational durability tests to verify the lifespan of car sun visors.

[0003] For example, Chinese patent application number CN202022216482.8, patent title: Side rollover durability test device for automobile sun visor. The technical solution described in this embodiment, "The side-flipping durability testing device for automotive sun visors includes a base frame and a drive mechanism. The base frame has a rotating hole for inserting a shaft at one end of the sun visor, and a slot for securing the other end of the sun visor. The drive mechanism includes a first drive assembly, a second drive assembly, and a third drive assembly, respectively mounted on the base frame. The first drive assembly drives the sun visor to rotate, the second drive assembly drives the sun visor to disengage from the slot, and the third drive assembly drives the sun visor to engage in the slot. When the second drive assembly drives the sun visor to disengage from the slot, the first drive assembly drives the sun visor to side-flip. When the sun visor reaches its maximum side-flipping position, the first drive assembly drives the sun visor back to the slot, and the third drive assembly drives the sun visor to engage in the slot, completing one side-flipping cycle," achieves the technical effect of "automatically testing the durability of automotive sun visors, thus reasonably testing the side-flipping durability of automotive sun visors, replacing manual operation, and reducing labor intensity."

[0004] This structure, which requires a first drive component, a second drive component, and a third drive component, is relatively complex and has a high manufacturing cost. Utility Model Content

The clamping head is provided with an elastic clamping piece for clamping the fixing shaft of the car sun visor. The alignment of the elastic clamping piece is the arc-shaped part of the clamping head. The purpose of this design is that the structure of the elastic clamping piece and the arc-shaped part allows the fixing shaft of the car sun visor to be inserted and fixed, thereby fixing the other end of the car sun visor.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example 1 Please refer to Figure 1 -7.

[0024] This embodiment provides a sun visor flipping durability test fixture, including a base 1 as the complete fixture, a frame 2 mounted on the base 1, a horizontal support 3 mounted on the frame 2, and a clamping part 4 mounted under the horizontal support 3. The clamping part 4 is used to clamp the car sun visor 5. The clamping part 4 includes a right clamping block 7 that is inserted into the base 6 of the car sun visor 5, and a left clamping block 9 that is inserted into the fixing shaft 8 of the car sun visor 5. The right clamping block 7 and the left clamping block 9 are fixed on a connecting plate 10, and the connecting plate 10 is fixed on the horizontal support 3 by a connecting block 11.

[0025] This suspended installation simulates the actual installation of a car sun visor on a car, making the experimental environment closer to the real-world usage situation.

[0026] A drive unit 12 is mounted on the frame 2. The function of the drive unit 12 is to flip the car sun visor 5, simulating the rotation of the car sun visor 5. The drive unit 12 includes a drive element 13 as a power source. A rack 14 is connected to the front end of the drive element 13. A gear 15 meshes on the rack 14. A transmission shaft 16 for transmitting power is mounted on the gear 15. The transmission shaft 16 is fixed by a fixed baffle 38.

[0027] Furthermore, the fixed baffle 33 is provided with an angled arc-shaped slot 37, which, in conjunction with the stop pin, can control the test rotation angle range of the car sun visor 5.

[0028] A rocker arm 17 is fixed on the drive shaft 16, and a clamping rod 19 for clamping the sun visor body 18 of the car sun visor 5 is fixed on the rocker arm 17.

[0029] Furthermore, the rocker arm 17 is provided with a rocker arm slot 36, which can adjust the up and down position of the clamping rod 19, thereby satisfying the flipping clamping and fixing of car sun visors 5 of different widths.

[0030] It should be noted that the driving element 13 is a cylinder, or it can be a motor, etc. Since the control principle of this driving element 13 (such as PLC control) is existing technology, it will not be described in detail here.

[0031] In the embodiments of this utility model application, please refer to Figure 4The right clamping block 7 is provided with a first mounting hole 21 for interlocking with the fixing pin 20 on the base 6 of the car sun visor 5, and a second mounting hole 23 for interlocking with the intermediate pin 22 on the base 6 of the car sun visor 5. Taking advantage of the existing two fixing pins 20 and one intermediate pin 22 on the base 6 of the car sun visor 5, two first mounting holes 21 and one second mounting hole 23 are adaptively provided to achieve interlocking, fix the base 6, and thus fix one end of the car sun visor 5.

[0032] In the embodiments of this utility model application, please refer to Figure 5 The left clamping block 9 consists of a left clamping seat 24 and a clamping head 25. The clamping head 25 is provided with an elastic clamping piece 26 for clamping the fixing shaft 8 of the car sun visor 5. The alignment of the elastic clamping piece 26 is the arc-shaped portion 34 of the clamping head 25. The structure of the elastic clamping piece 26 and the arc-shaped portion allows the fixing shaft 8 of the car sun visor 5 to be inserted and fixed, thereby fixing the other end of the car sun visor 5.

[0033] In the embodiments of this utility model application, please refer to Figure 6 The chuck 25 is provided with a threaded pin 27 and a square block 28. The left clamp 24 is provided with a third mounting hole 29 for interlocking with the threaded pin 27. The left clamp 9 is provided with a fourth mounting hole 30 for interlocking with the square block 28. The left clamp 24 and the chuck 25 are combined to form a left clamp 9.

[0034] In the embodiments of this utility model application, please refer to Figure 3 The connecting plate 10 is provided with a long slot 31, and the connecting block 11 is provided with a short slot 35. By changing the fixed positions of the left clamping block 9 and the right clamping block 7 on the long slot 31, the experimental installation and fixing of car sun visors 5 of different lengths can be satisfied.

[0035] In the embodiments of this utility model application, please refer to Figure 7 The clamping rod 19 is U-shaped. The U-shaped clamping rod 19 can easily clamp and remove the car sun visor 5.

[0036] This embodiment provides a fixture for a sunshade flipping durability test. Please refer to [reference needed]. Figure 1 In normal use, the car sun visor 5 is first clamped in the clamping part 4. Under the action of the drive element 13, the gear 15 rotates about 90 degrees (simulating the working state), which drives the rocker arm 17 to rotate. The rocker arm 17 drives the flip cover 32 to rotate. Under the reset of the drive element 13, the flip cover 32 also resets synchronously. The test is repeated continuously.

[0037] Compared with the prior art, the advantages of this utility model are: it only requires one driving element 13 to achieve flipping, the whole structure is relatively simple, the manufacturing cost is low, and it can be suitable for flipping durability tests of sunshades of different lengths and widths.

[0038] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
