Description

Technical Field

[0001] The utility model relates to the technical field of bond strength testing, in particular to a bond strength testing device for a frameless side window assembly structure. Background Technique

[0002] Vehicles of multiple brands and models have adopted the frameless glass design. This design not only improves the aesthetics of the vehicle but also enhances the openness of the field of vision, bringing a more transparent and open driving and riding experience to drivers and passengers.

[0003] The frameless glass assembly structure includes a door clip and glass, and the two are connected by means of adhesive bonding, clamping fixtures or other hidden bolt fixing methods. Taking the frameless glass assembly structure fixed by adhesive bonding as an example, it uses glass glue to directly bond the glass to the door clip, which is applicable to flat and curved glass and has the advantages of high transparency and overall beauty.

[0004] The frameless glass assembly structure fixed by adhesive bonding needs to meet a certain bond strength to cope with some harsh environments (for vehicles with frameless glass in cold environments, the glass and the sealing strip are frozen for a long time, resulting in cracking or breaking of the glass when the door is opened). It is very necessary to test the bond strength of the frameless glass assembly structure, which is closely related to the driving and riding safety of drivers and passengers.

[0005] At present, the bond strength test of the frameless glass assembly structure is carried out manually. The frameless glass assembly structure is fixed on a simple fixture, and the operator shakes the assembly structure to observe the bonding situation. This test method has the disadvantages of uneven structural stress and few test cycle times, and there is also a safety problem of glass breaking and injuring people.

[0006] Therefore, it is necessary to improve the existing technology. Content of the Utility Model

[0026] Please refer to Figures 1 to 3 , the first embodiment of the present invention provides a device for testing the bond strength of a frameless side window assembly structure, including: a frame 1, on which a first horizontal bracket 2 and a second horizontal bracket 3 are arranged in parallel;

[0027] A door clip fixing assembly 4 is provided on the first horizontal bracket 2 for clamping the door clip 8 of the frameless side window assembly structure, so that the side window glass 9 is in an upright state, simulating the position of the side window glass 9 during use.

[0028] A column 5 is provided on the second horizontal bracket 3. An electric motor drive assembly 6 and a push rod 7 are provided on the column 5. The push rod 7 points to the side window glass 9. The electric motor drive assembly 6 drives the push rod 7 to move in a straight line direction, applying pressure to the side window glass 9, and using the reciprocating movement of the push rod 7 to simulate the stress condition of the side window glass 9 when opening the car door in a frozen environment.

[0029] Specifically, a rubber head is provided at the end of the push rod 7 for contacting the side window glass 9 to avoid damaging the glass.

[0030] The first horizontal bracket 2 is made of a square tube and has a first horizontal groove. The door clip fixing assembly 4 includes a door clip fixing block 41 and a locking screw 42. The door clip fixing block 41 is arranged on the first horizontal bracket 2 and is detachably connected. The door clip fixing block 41 has an embedding groove for placing the door clip 8. The locking screw 42 penetrates through one side of the door clip fixing block 41 to lock the door clip 8 in the embedding groove.

[0031] The door clip fixing block 41 has two flanks. Waist-shaped holes are provided on the flanks. Screws pass through the waist-shaped holes and are screwed into the first horizontal groove and tightened to fix the door clip fixing block 41 to the first horizontal bracket 2. By removing the screws, the distance between the two door clip fixing blocks 41 can be adjusted to adapt to different frameless side window assembly structures. The position of the screws relative to the waist-shaped holes can also be adjusted to change the distance between the side window glass 9 and the push rod 7.

[0032] Specifically, a locking guide block 65 is further provided on one side of the door clip fixing block 41. The locking screw 42 sequentially penetrates through the locking guide block 65 and one side of the door clip fixing block 41, and then locks the door clip in the embedding groove.

[0033] Specifically, a handle is provided at the end of the locking screw 42 for easy operation.

[0034] The electric motor drive assembly 6 includes an installation platform 61, an electric motor, a transmission gearbox, a rotating shaft 62, a rocker 63, a connecting rod 64 and a guide block 65. The installation platform 61 is arranged on the upper section of the column 5. The rotating shaft 62 penetrates through the installation platform 61 and is vertically arranged. The lower end is driven by the electric motor through the transmission gearbox, and the upper end is fixedly connected to one end of the rocker 63. Both ends of the connecting rod 64 are respectively rotatably connected to the other end of the rocker 63 and one end of the push rod 7. The guide block 65 is arranged on the installation platform 61 and has a linear through hole. The push rod 7 is arranged in the linear through hole. When the electric motor drives the rotating shaft 62 to rotate, the rocker 63 rotates around the fixed end, driving the push rod 7 to reciprocate in the linear through hole. When the rocker 63 rotates one circle, the push rod 7 pushes the side window glass 9 once.

[0035] Specifically, the side of the installation platform 61 has an installation section, and installation holes are provided on the installation section. The side of the column 5 has a vertical groove. The installation screw passes through the installation hole and is screwed into the vertical groove and tightened, fixing the installation platform 61 to the side of the column 5. By adjusting the height of the installation platform 61, it can adapt to different sizes of the side window glass 9.

[0036] In order to test the bonding strength of multiple points on the upper edge of the frameless side window, the column 5 needs to be set to be detachable and adjustable:

[0037] The second horizontal bracket 3 has a second horizontal groove. The bottom of the column 5 has a connection section, and connection holes are provided on the connection section. The screw passes through the connection hole and is screwed into the second horizontal groove and tightened, fixing the column 5 to the second horizontal bracket 3. By adjusting the position of the column 5 on the second horizontal bracket 3, different positions of the side window glass 9 can be tested.

[0038] Specifically, a scale is also provided on one side of the second horizontal bracket 3, which is beneficial for adjusting to the set test points.

[0039] A method for testing the bonding strength of the frameless side window assembly structure using this bonding strength testing device:

[0040] Adjust the two door clip fixing components to a suitable distance and clamp the frameless side window assembly structure; determine multiple test points according to the width of the side window, and adjust and fix the column according to the position of the first test point;

[0041] Adjust the motor drive component so that the time for the push rod to act once is 20 s and the thrust is 100 N; start the motor to test the test point for 10 minutes (the number of actions is 30 times), observe whether the side window glass and the door clip are separated. If they are separated, the bonding strength is insufficient and the product is defective; adjust the position of the column in turn and test the remaining test points, and finally judge whether the product is qualified.

[0042] In the second embodiment of the present invention, only the adjustment method of the column is changed, and the rest of the design is the same as that of the first embodiment:

[0043] The second horizontal bracket is provided with a horizontal guide rail. The bottom of the column is slidably arranged on the horizontal guide rail through a slider. The position of the slider is adjusted by a driving unit to make the push rod reach the set test point, and the bonding strength of multiple test points can be tested without manually adjusting the position of the column, and the test efficiency is higher.
