Description

Technical Field

[0001] The utility model relates to the technical field of automobile window testing, and particularly relates to a device for testing the anti-pinch force of an automobile window. Background Art

[0002] With the mandatory requirements of automobile safety regulations and the improvement of consumers' safety needs, the window anti-pinch function has become one of the core safety configurations of passenger cars. Its performance directly relates to the personal safety of passengers (especially children) during the window closing process. When the window detects an obstacle, it needs to stop closing or reverse running through the control of the anti-pinch force threshold. Therefore, a special device is required to accurately measure the anti-pinch force of the window to verify whether it meets the safety standards. However, the existing window anti-pinch force testing devices have obvious technical shortcomings: most devices rely on complex structures such as bolts and suction cups for fixation, and need to be repeatedly adjusted to align with the window, which is cumbersome to operate; and it is easy to shift due to window vibration or closing impact force after fixation, resulting in the deviation of the contact position of the pressure sensor, and the test data has a large deviation. In addition, the window is easily damaged during the installation tightening and test extrusion processes, increasing the test cost. Summary of the Invention

[0003] The purpose of the utility model is to provide a device for testing the anti-pinch force of an automobile window to overcome the above defects in the prior art.

[0004] A device for testing the anti-pinch force of an automobile window includes a mounting frame, a pressure sensor and an extrusion block. A rubber pressing pad is provided on the inner wall of the mounting frame. A plurality of threaded rods are threadedly connected to the side surface of the mounting frame. A rubber pressing head is provided at the inner end of the threaded rod. The fixed end of the pressure sensor is fixed to the top of the mounting frame. The extrusion block is arranged at the measuring end of the pressure sensor. A groove for contacting the top wall of the window is provided at the top of the extrusion block. A rubber buffer pad is provided in the groove.

[0005] Preferably, the mounting frame is of a "U" - shaped structure with the opening facing downwards.

[0006] Preferably, the rubber pressing pad is of an "L" - shaped structure.

[0007] Preferably, the groove is of an arc - shaped structure, and the rubber buffer pad is adhered in the groove.

[0008] Preferably, there are two threaded rods, which are symmetrically arranged on both sides of the mounting frame.

[0009] Preferably, a turning handle is provided at the outer end of the threaded rod.

[0010] Preferably, a handle is provided on the outer side of the mounting frame.

[0011] The beneficial effects achieved by the utility model are as follows: The mounting bracket of this application adopts a U-shaped opening facing downwards, which, together with the outer handle, can be quickly snapped into the corresponding position on the vehicle window without complicated assembly. The threaded rod on the side allows the operator to flexibly adjust the clamping force of the inner rubber pressure head, ensuring a stable fit between the device and the vehicle window, avoiding displacement problems during testing, and improving installation efficiency. The rubber pressure pad on the inner wall of the mounting bracket and the rubber buffer pad in the groove of the extrusion block form a double protection: the former, through elastic cushioning, isolates the metal mounting bracket from hard contact with the vehicle window glass, preventing scratches on the glass; the latter can absorb the impact stress when the vehicle window is closed, preventing the device from colliding with the top wall of the vehicle window and causing damage, extending the service life of the device and reducing the maintenance cost of the vehicle window.

[0019] As Figure 1-3 shown, the utility model provides a clamping force test device for automobile windows, which includes a mounting frame 1, a pressure sensor 3 and a pressing block 4; In addition, the mounting frame 1 is of a "U" - shaped structure with the opening facing downwards, and can be directly sleeved onto the window glass from above the window glass, without complex disassembly or assembly steps, thus improving the operation efficiency; Furthermore, a handle 12 is provided on the outer side of the mounting frame 1, which is convenient for operators to pick up and move the device. Especially during multi - window tests, it can be quickly transferred. During installation, the position of the device can be finely adjusted through the handle 12. A rubber gasket 11 with an "L" - shaped structure is provided on the inner wall of the mounting frame 1. The rubber material is soft, which can avoid hard contact between the inner wall of the mounting frame 1 and the window glass, preventing scratches or indentations; However, threaded rods 2 are symmetrically connected to both sides of the mounting frame 1. A rubber pressing head 21 is provided at the inner end of the threaded rod 2. The rubber pressing head 21 replaces the metal end of the threaded rod 2 to directly contact the frame, preventing metal scratching and damaging the window glass. A turning handle 22 is provided at the outer end of the threaded rod 2. The turning handle 22 provides a convenient force - applying point. Without the need to use tools such as wrenches or pliers, the tightness of the threaded rod 2 can be quickly adjusted manually, improving the operation convenience. The fixed end of the pressure sensor 3 is fixed to the top of the mounting frame 1, In addition, the pressing block 4 is arranged at the measuring end of the pressure sensor 3. An arc - shaped groove 41 for contacting the top wall of the window is provided at the top of the pressing block 4. A rubber buffer pad 42 is adhered in the groove 41. The rubber buffer pad 42 can buffer the collision force between the top wall of the window and the pressing block 4, avoiding scratches caused by hard contact. The rubber material has a certain elasticity, which can make the window and the pressing block 4 fit tightly, reducing the pressure loss caused by gaps, and improving the authenticity of the measured force data. Specific implementation method and principle: Installation and positioning: The operator uses the handle 12 on the outer side of the mounting frame 1 to clamp the mounting frame 1 through its opening at the corresponding position of the automobile window glass, and rotates the threaded rod 2 on the side of the mounting frame 1. The threaded rod 2 pushes the rubber pressing head 21 at its inner end to press tightly against the window glass. At the same time, the rubber gasket 11 on the inner wall of the mounting frame 1 fits the surface of the window glass. On the one hand, it enhances the friction between the mounting frame 1 and the window glass, avoiding the displacement of the device during the test. On the other hand, through the buffering of the rubber material, it prevents the mounting frame 1 or the window glass from being damaged due to hard contact; Anti-pinch force test: After installation and fixation, control the window glass to rise according to the normal closing process. When the groove 41 on the squeezing block 4 contacts the top wall of the window, it will apply pressure to the rubber buffer pad 42 in the groove 41. The pressure is transmitted to the squeezing block 4, and then the squeezing block 4 transmits the force to the measuring end of the pressure sensor 3, and converts the pressure signal into an electrical signal or a readable value. Finally, the pressure data applied to the window is obtained through the matching data acquisition equipment. This data is the measured value of the window anti-pinch force, and one anti-pinch force test is completed.

[0020] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
