[0001] This utility model relates to the field of puncture resistance testing devices, specifically a puncture resistance testing device for automotive glass films. Background Technology

[0002] Automotive window film is a multi-layered functional polyester film applied to the inside of automotive glass. It is made by laminating layers of different materials (such as dyed layers, metal layers, ceramic layers, etc.) together through a special process to achieve various effects. Different types of films have different tensile and elongation properties. To test their performance, specialized instruments are used in manufacturing to perform puncture tests on the films. By measuring the length of the film's elongation during puncture, the film's performance is accurately determined.

[0003] Patent application number 202420671799.6 discloses a membrane puncture testing device, comprising: a housing; a membrane fixing plate connected to the housing, wherein the membrane fixing plate has a through hole in the middle in a horizontal direction, and the number of membrane fixing plates is not less than two; a translation device disposed on the housing, wherein the translation device is drivenly connected to a pusher, and the translation device can drive the pusher to move closer to or away from the membrane fixing plate, wherein a puncture rod is connected to the pusher at a position opposite to the multiple through holes.

[0004] The aforementioned membrane puncture test device uses a plate-shaped membrane fixing plate to position the membrane to be tested. However, when the puncture rod applies pressure to the surface of the glass membrane, the glass membrane slides on the side wall of the membrane fixing plate, resulting in poor stability of the glass membrane during the puncture resistance test.

[0008] The present invention is further configured such that the outer wall of the base plate is integrally formed with protrusions in a ring array, and a through hole is provided at the center of the protrusions.

[0009] The present invention is further configured such that the movable end of the electric push rod protrudes from the top of the mounting plate, and a piercing rod is fixedly sleeved on the movable end of the electric push rod.

[0010] The present invention is further configured such that a pressure groove is provided at the top of the top plate, and a protrusion that fits into the pressure groove is integrally formed at the bottom of the top plate.

[0011] The present invention is further configured such that fastening bolts are installed in a rectangular array at the bottom end of the convex plate, and multiple fastening bolts are threaded into the top plate.

[0012] The present invention is further configured such that screw holes are provided on both sides of the bottom end face of the top plate, and the top end of the knob bolt is threaded into the screw hole.

[0013] The present invention is further configured such that the knob bolt is slidably engaged in the convex plate, and the knob bolt abuts against the bottom end of the convex plate.

[0014] In summary, the present invention has the following advantages: By installing a pressure ring at the top of the top plate, the automotive window film is placed at the top of the top plate during testing.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] A puncture resistance testing device for automotive window film, such as Figure 1-5 As shown, the device includes a mounting plate 2 and a top plate 4 fixed above the mounting plate 2. A support mechanism is provided below the mounting plate 2, and an electric push rod 6 is fixedly installed at the bottom end of the mounting plate 2. A puncture groove is provided at the center of the top plate 4, and a pressure ring 3 for fixing the automotive window film is sleeved on the top of the top plate 4. Both sides of the bottom end face of the top plate 4 are fixed with protruding plates 12, and the bottom end of the protruding plates 12 is equipped with a knob bolt 11 for fixing the pressure ring 3. By installing the pressure ring 3 at the top of the top plate 4, the automotive window film is placed on the top of the top plate 4 during testing. The knob bolt 11 is threaded into the screw hole 14 at the bottom end of the pressure plate, so that the pressure ring 3 presses and fixes the automotive window film, which facilitates the pressing and fixing of the automotive window film under test and improves the stability of the automotive window film during the puncture resistance test.

[0023] The support mechanism includes a base plate 1 and support rods 5 arranged in a ring array and fixed to the top of the base plate 1. Multiple support rods 5 are respectively fixedly inserted into the mounting plate 2 and the base plate 1. The outer wall of the base plate 1 has protrusions 13 integrally formed in a ring array. A through hole 8 is opened at the center of the protrusions 13. Multiple support rods 5 keep the mounting plate 2 and the top plate 4 fixed above the base plate 1. When in use, screws are installed at the top of the protrusions 13 and threaded into the table through the through hole 8 to keep the base stable during use.

[0024] Furthermore, a pressure groove 10 is provided at the top of the top plate 4, and a protrusion 13 that fits into the pressure groove 10 is integrally formed at the bottom of the top plate 4. The pressure groove 10 increases the contact area between the top plate 4 and the glass film, and improves the stability of the glass film being pressed and fixed after the pressure ring 3 is pressed downward.

[0025] Furthermore, fastening bolts 15 are installed in a rectangular array at the bottom end of the convex plate 12. Multiple fastening bolts 15 are threaded into the top plate 4. Screw holes 14 are provided on both sides of the bottom surface of the top plate 4. The top of the knob bolt 11 is threaded into the screw hole 14. The knob bolt 11 is slidably engaged in the convex plate 12, and it abuts against the bottom end of the convex plate 12. When the knob bolt 11 is threaded into the screw hole 14, it contacts the bottom end of the convex plate 12, and during continuous tightening, it drives the pressure plate downwards. The pressure plate moves downwards, pressing and fixing the glass film at the top of the top plate 4. The moving end of the electric push rod 6 protrudes from the top of the mounting plate 2, and a puncture rod 16 is fixedly sleeved on the moving end of the electric push rod 6. After the glass film is pressed and fixed, the electric push rod 6 is activated to drive the puncture rod 16 to move upwards. During the upward movement of the electric push rod 6, it passes through the puncture hole 9 at the center of the top plate 4 and applies pressure to the surface of the glass film. The puncture resistance of the glass film is tested by observing the state of the glass film.
